Definitions
- the exemplary and non-limiting embodiments of this invention relate generally to wireless communication systems, methods, devices and computer programs and, more specifically relate to cross scheduling from one component carrier or cell to another during a random access procedure.
- LTE E-UTRAN evolved UTRAN
- Figure 1A is exemplary; in practice there may be more or less than five CCs, they may not have equal bandwidths, they may be frequency non-adjacent, and LTE-A is considering the case where one or more secondary CCs are in unlicensed spectrum.
- the CCs could be aggregated in both time division duplex TDD and frequency division duplex FDD systems.
- FIGS 1 A-B ill ustrate d ifferent exemplary scenarios in wh ich CA may be employed.
- a macro cell F1 e.g., a traditional cellular base station
- RRHs remote radio heads
- F2 RRHs cells can be aggregated with the underlying F1 macro cells.
- a U E would communicate with the F1 cell on one CC (typically the PCC) and with the F2 cells on different CCs (SCCs). These different CCs are seen by the U E as different cells.
- Figure 1 C illustrates a different CA scenario, similar to that of Figure 1 B but in which frequency selective repeaters are deployed so that coverage is extended for one of the carrier frequencies. It is expected that F1 and F2 cells of the same eN B can be aggregated where coverage overlaps. In this case also the UE will see the different CCs as different cells where the F1 and F2 cells are operating on different frequencies/different CCs.
- the PDCCH which informs the individual U Es which radio resources are allocated for their traffic could only be used to indicate a PDSCH/PUSCH sent on its own DL CC or its paired UL CC (since using the hindsight of CA the Release 8 spectrum can be considered as only one CC).
- "cross-scheduling" can be available, which means the PDCCH could be used to indicate PDSCH/PUSCH resources sent on other CCs other than its own DL CC and/or its paired UL CC. From the perspective of the transmitted PDCCH this cross-scheduling is useful for distributing traffic loads among the multiple carriers.
- the eNB signals a timing advance (TA) to the UE as detailed at 3GPP TS 36.321 v10.1 .0 (201 1 -03) at section 5.2.
- TA timing advance
- the UE adjusts its uplink transmission timing as detailed at 3GPP TS 36.213 v10.0.1 (2010-12) section 6.1 .1.
- a timing advance command can be received in a random access response or in a MAC control element. The validity of a timing advance command is controlled by the TA timer in the UE.
- the timing advance remains valid and uplink transmissions can take place on the shared channel .
- the TA timer is restarted .
- uplink synchronization is required and no uplink transmission can take place on the shared channel.
- 3GPP Release 10 specifies that cross carrier scheduling may be used to schedule resources on a cell from another cell.
- the carrier indicator field (CIF) allows the PDCCH of a serving cell addressed to a UE's C-RNTI to identify another cell in which the scheduled resources lie, but 3GPP 36.300 v10.3.0 (201 1 -03) at section 1 1.1 sets forth the following restrictions:
- PCell is always scheduled via its PDCCH
- each CA-capable UE is configured with one PCell and optionally one or more SCells as its Serving Cell(s) but regardless the UE will have only one RRC connection with the network.
- the PCell is the one which provides the U E with its network access stratum mobility information, which is done at RRC connection establishment, re-establishment or handover.
- the PCell is the one the UE uses for PUCCH transmissions, and unlike SCells once established the PCell can be changed only with a handover procedure and cannot be de-activated.
- the UE would not perform blind decoding in common search space of the SCells, as it is not expected to receive system information (scheduled by PDCCH addressed to S I-RNTI), nor paging (scheduled by PDCCH addressed to P-RNTI), nor random access response (scheduled by PDCCH addressed to RA-RNTI) on SCells. If supporting RACH procedure on SCell and the RAR of the SCell is scheduled from SCells, it would increase the number of blind decoding the UE needs to support. From this perspective, even if cross scheduling of the SCell is not configured, it would be beneficial if the RAR can be signaled from the PCell so that the UE only needs to decode the common search space of the PCell.
- an apparatus comprising at least one processor and at least one memory including computer program code.
- the at least one memory and the computer program code are configured, with the at least one processor, cause the apparatus at least to: perform a random access procedure in which a downlink random access response from a network node to a user equipment indicates a timing advance for a component carrier or cell of a plurality of component carriers or cells, or a group of component carriers or cells, to which the timing advance applies; and thereafter to operate a wireless radio on the indicated one or group of component carriers or cells synchronous with the timing advance.
- a method comprising: performing a random access procedure in which a downlink random access response from a network node to a user equipment indicates at least a timing advance for a component carrier or cell of a plurality of component carriers or cells, or a group of component carriers or cells, to which the timing advance applies; and thereafter operating a wireless radio on the indicated one or group of component carriers or cells synchronous with the timing advance.
- a computer readable memory storing a program of computer readable instructions that when executed by a processor result in actions comprising: performing a random access procedure in which a downlink random access response from a network node to a user equipment indicates at least a timing advance for a component carrier or cell of a plurality of component carriers or cells, or a group of component carriers or cells, to which the timing advance applies; and thereafter operating a wireless radio on the indicated one or group of component carriers or cells synchronous with the timing advance.
- Figure 1 A is a schematic diagram of a radio spectrum in which cross-scheduling can be employed, in which five component carrier bandwidths are aggregated into a single LTE-Advanced bandwidth.
- Figures 1 B-C illustrate different scenarios in which a U E would need multiple independent timing advances for different cells/component carriers, and are two exemplary environments in which embodiments of the invention may be practiced to advantage.
- Figures 2A-B illustrate two MAC subheaders of size one octet as detailed at 3GPP TS 36.321 V10.1 .0 (201 1 -03).
- Figure 2C illustrates a MAC random access response of size six octets as detailed at 3GPP TS 36.321 v10.1 .0 (201 1 -03).
- Figure 2D illustrates the MAC subheaders and MAC random access response of Figures 2A-C assembled with optional padding bits into a MAC PDU for random access as detailed at 3GPP TS 36.321 v10.1.0 (201 1 -03).
- Figure 3A illustrates a random access response message according to first and second exemplary implementations as detailed further herein.
- Figures 3B-C illustrate a random access response message according to respective third and fourth exemplary implementations as detailed further herein
- Figure 4 is an exemplary flow diagram illustrating various embodiments of the invention from the perspective of the UE and of the eNB/network node.
- FIG. 5 is a simplified block diagram of a UE and an eNB which are exemplary electronic devices suitable for use in practicing the exemplary embodiments of the invention.
- the non-contention RACH procedure in LTE and LTE-A is as follows. First, the eNB assigns a RACH preamble to the UE via dedicated signaling. Second, the UE then sends its assigned preamble on the RACH , followed by the eN B's random access response on a DL shared channel (which maps from the UE's message containing the preamble) scheduled by PDCCH and addressed to a RA-RNTI .
- a DL shared channel which maps from the UE's message containing the preamble
- That random access response assigns U L resources to the U E and gives the absolute timing for the UE to synchronize against.
- the U E randomly selects the preamble.
- Figures 2A-D detail the network's conventional random access response in more detail.
- Figures 2A-D are taken from 3GPP TS 36.321 v10.1 .0 (201 1 -03) at section 6.1 .5 describing the MAC PDU for random access, which carries the network's random access response message (to one or multiple UEs).
- the MAC PDU consists of a MAC header and zero or more MAC random access responses, optionally with padding bits as will be shown.
- the MAC PDU header itself consists of one or more sub-headers of one octet (8- bits) each .
- Figures 2A-C are arranged in a MAC PDU for random access as shown at Figure 2D. The various subheaders are arranged seriatim followed by the various MAC random access responses (RARs in Figure 2D), with padding bits (if present) following the last MAC random access response. Each individual UE gets one subheader and one MAC random access response, identified by the same index [1 ,2,...n] in Figure 2D.
- a U E's different configured CCs/Cells may be arranged into TA groups; all CCs/Cells in an individual group can apply the same TA. So for example if there is configured for a UE a PCell, SCell#1 and SCell#2, in one case the PCell and SCell#1 may be in one TA group while SCell#3 is in a different TA group, and in another case each of the three configured Cells have their own timing and none two of them are grouped under the same TA.
- a first implementation assumes that there are only at most two TA groups.
- U E knows how its configured Cells are grouped TA-wise, and so identifying the TA group for the U E also identifies the group of CCs/Cells which are the members of that TA group.
- This first implementation is shown at Figure 3A, in which the first bit position 302A of the first octet of the random access response 300A is used to indicate which TA group applies for the TA command .
- bits labeled cell index 308 shown at Figure 3A are used for that purpose in the second implementation , but for this first implementation for the case that there is no U L resource grant 306A in the random access response 300A (or if there is only one CC/Cell in the U E's TA group indicated at bit 302A) those bits 308A are reserved bits 31 0 and not used to signal information.
- the random access response 300A does include an UL resource grant 306A and/or if there is more than one CC/Cell in the indicated TA group, then those bits 308A indicate the index of the specific CC/Cell within the TA group identified at the first bit position 302A to which the U L resource grant 306A applies.
- the UE will apply the indicated TA 304A to all the CCs/Cells in the TA group identified by that TA-group identifier bit 302A.
- the first bit position 302A of the first octet at Figure 3A is particularly defined to indicate a TA group as opposed to its conventional purpose of being reserved/not used in Figure 2C.
- a second implementation dispenses with the assumption above for the second i mplementation , and so there may be more than two TA groups.
- This second implementation is also shown at Figure 3A and uses the first bit position 302A of the first octet as a flag to indicate that there is CC/cell/group information included in the random access response 300A (i.e. the TA and the UL resources identified in the random access response is for a CC/Cell different from that on which the random access response was sent).
- the cell index is indicated by some of the bit positions in the last two octets of the random access response, shown in Figure 3A within the fifth octet as the three cell index bits 308A.
- these bits 308A would all be reserved and not used.
- Figure 2C shows these last two octets (with bits 308A and 310) as being used for the temporary C-RNTI field.
- the second implementation re-defines bit meanings from their conventional understanding.
- the random access response 300A of Figure 3A may also be further adapted to support contention-based RACH by adding a seventh octet to give room for the CC/Cell index 308A, in case the Temporary C-RNTI at the fifth and sixth octets of Figure 2C cannot be omitted.
- the third implementation utilizes a new format for the random access response shown by example at Figure 3B.
- a leading bit 302B is a type flag indicating this random access response 300B has the new format, followed by a three-bit CC/Cell/group index 308C and an 1 1 -bit TA command 304A.
- the length of this new format random access response 300B is two octets there is no available space for signaling any U L granted resources; the UE can use this two-octet format random access response 300B in the non-contention based RACH procedure to get an updated TA value (e.g., if its TA timer has expired).
- the fourth implementation is also a new format for the random access response 300C shown at Figure 3C and can be used to signal a TA command 304C and CC/Cell index 308C with or without a granted UL resource.
- the network may use RRC signaling to explicitly configure the UE that this new format random access response 300C should be used.
- RRC signaling may be used to explicitly configure the UE that this new format random access response 300C should be used.
- its use may be implicit whenever cross scheduling is configured and RACH is configured on the Cell.
- the U E finds its matched preamble I D (RAPID in the subheader as in Figure 2A), it knows how to interpret the random access response.
- This configuring of the random access response format can be used for any of the above embodiments.
- the first bit 30-2A, 302B may then simply be reserved and not carry any information for the UE.
- first bit 302A may still identify the TA group, or instead it may be reserved in which case the UE knows implicitly to apply the TA 304A in that random access response 300A to all CCs/Cells that are members of the same TA group as the CC/Cell identified by the index 308A.
- the network can inform the UE of a granted UL resource using a normal PDCCH (addressed to the UE's C- RNTI) which has a carrier indication field, once the UE obtains UL synchronization on the new CC/Cell following the RACH procedure of which the random access response 300B, 300C is a part.
- a normal PDCCH addressed to the UE's C- RNTI
- the UE obtains UL synchronization on the new CC/Cell following the RACH procedure of which the random access response 300B, 300C is a part.
- contention-based or non-contention based each of the random access responses detailed above for the RACH procedure are addressed to the RA-RNTI.
- the third and fourth implementations it is convenient to put those new- format random access responses 300B, 300C as the last entry/entries in the MAC PDU (see Figure 2D) in order to facilitate backward compatibility with legacy user equipments reading their conventional random access responses in that same PDU.
- the first and second implementations are the same size as conventional random access responses and need not be segregated to assure backward compatibility in the same PDU.
- the network send the random access response always on the PCell, identifying the CC/Cell/TA group to which the TA (and UL resource if included) applies in that random access response.
- the UE then follows the RACH procedure for the indicated CC/Cell/Group, including apply the TA to the indicated CC/Cell/Group, start its TA timer for the CC/Cell/Group, transmit PUSCH on the granted U L resources on the indicated CC/Cell and transmit at a time which depends on the TA .
- One technical effect of these embodiments is that cross carrier scheduling during a RACH procedure is supported without impacting the physical layer blind decoding effort which the U E conducts.
- the random access responses detailed above are scheduled by a PDCCH addressed to the RA-RNTI in the U E's common search spaces and so there is no change for the PDCCH addressed to the RA-RNTI . Therefore these techniques reduce the number of blind decodings the UE needs to support as well as the PDCCH overhead since individual random access responses for different UEs for different Cells can be put in one Random Access Response PDU, the same as the existing random access responses for different UEs where cross scheduling is not allowed as was the conventional practice (and so all random access responses were for the same CC/Cell).
- FIG. 4 is a logic flow diagram that illustrates the operation of a method, and a result of execution of computer program instructions, in accordance with the exemplary embodiments of this invention .
- a random access procedure in which a downlink random access response from a network node to a user equipment indicates at least a timing advance and an explicit indication identifying one component carrier or cell of a plurality of component carriers or cells or a group of component carriers or cells, to which the timing advance applies.
- a wireless radio is operated on the indicated one or group of component carriers or cells synchronous with the timing advance of block 402.
- Stating in the manner of blocks 402 and 404 reads on both the network node/eNB and the UE (or one or more components therefore).
- the eNB which compiles and sends the DL random access response at block 402.
- the network node remains synchronized on the one or group of CCs/Cells throughout, it nonetheless receives the U E's U L transmission on the U L resources granted in the random access response (if such UL resources were granted, and if not still the network node transmits and receives on that one or group of CCs/Cells) and so its synchronization is consistent with the TA it provided to the UE in the random access response.
- the UE receives the DL random access response of block 402, applying the TA to the one or group of CCs/Cells as indicated in the random access response and transmit PUSCH on the indicated resource (if any).
- Remaining blocks of Figure 4 are optional particular embodiments, any of which may be combined with blocks 402 and 404 and any of which read on both the network side and the UE side of the wireless divide.
- Block 406 describes various implementations in which the DL random access response does grant an UL resource to the UE, in which case the UE transmits PUSCH on the uplink resource on the indicated one or group of component carriers or cells to which the timing advance is applied.
- the network node receives that same PUSCH.
- Block 408 describes the first implementation above; the random access response (300A) identifies the group of component carriers or cells by a single bit (302A) indicating a timing advance group. For the case in which there is more than one CC/Cell in the indicated group and there is also an UL resource grant in the random access response, then also the random access response includes an index (308A) identifying one component carrier or cell within that timing advance group. In this case the TA applies to all CCs/Cells in the group (regardless of whether any UL resource grant is included), and the UL resource grant applies only to the identified one CC/Cell within the TA group.
- Block 41 0 describes the second implementation above; the random access response (300A) identifies the one component carrier or cell or group by an index (308A), and the random access response further comprises a flag bit (302A) that indicates the index is included in the random access response.
- Block 412 describes the third implementation above; the random access response (300B) identifies the one component carrier or cell or group by an index (308B), and the random access response further comprises a flag bit (302B) that indicates a format of the random access response, the d ifferent formats either having or not havi ng the CC/Cell/group index included in the random access response.
- the two options whether or not this third implementation includes the UL resource grant are also summarized: if the random access response (300B) lacks any identification of an uplink resource granted to the U E it may be shorter (e.g.
- Block 414 describes the fourth implementation above where the format (whether or not the response includes a CC/Cell/group index) is explicitly indicated to the UE apart from the random access response itself; the random access response (300C) identifies the one or group of component carriers or cells by an index (308C), and the format of the random access response is identified in RRC signaling between the network node and the U E.
- the format (whether or not the response includes a CC/Cell/group index) is explicitly indicated to the UE apart from the random access response itself; the random access response (300C) identifies the one or group of component carriers or cells by an index (308C), and the format of the random access response is identified in RRC signaling between the network node and the U E.
- the two options whether or not this fourth implementation also includes the U L resource grant are the same as in block 412 but the RRC signaling indicates whether the CC/Cell/group index is included or not in the random access response.
- Block 416 describes the fourth implementation above where the format of the random access response is implicit; the random access response (300C) identifies the one or group of component carriers or cells by an index (308C), and the format whether the random access response includes such an index is implicit from a RACH and cross carrier sched uling being configured (where the RACH is used in the random access proceed u re fi rst stated at block 402 ).
- the two options wh eth er or n ot th i s fou rth implementation also includes the U L resource grant are the same as in block 412 but the implicit indication indicates whether the CC/Cell/group index is included or not in the random access response.
- the random access response of block 402 is considered a first RAR, then from the network's perspective it may schedule that first as well as other random access responses on a PCC/PCell (of the block 402 plurality of CCs/Cells), regardless of which CC/Cell the timing advance of the first and other random access responses applies.
- the network can send to the U E of block 402 as well as other UEs a MAC PDU which includes a plurality of random access responses. In this case the network would dispose the first random access response within the PDU to follow all other random access responses which lack an explicit indication identifying one or a group of CCs/Cells to which their respective TA applies.
- I n a particu lar embod i ment the network may use RRC signali ng to explicitly configu re the user equipment for the new format random access response which are detailed above.
- This configuring of the U E is different from the explicit or implicit format indication which identifies the format of a random access response as detailed in the above examples.
