- BSR buffer status report
- D-SR dedicated scheduling request
- the base station 310 may set a D-SR transmission resource to the terminal 305.
- the D-SR transmission resource is a resource allocated by the base station to the terminal to transmit the D-SR to the base station.
- the base station 310 may allocate a predetermined period to the terminal 305. Accordingly, in step 315, the base station 310 transmits a control message including the D-SR transmission resource configuration information to the terminal 305.
- the terminal 305 may know, through the control message, which transmission resource the D-SR transmission resource for the terminal 305 is set to and which subframe is available for use.
- step 320 it is assumed that a regular BSR is triggered in the terminal 305 at a point in time after step 315.
- a scheduling request (SR) transmission process is also triggered.
- the SR transmission process refers to a process of transmitting a D-SR to the base station until the terminal is allocated a radio resource for BSR transmission from the base station. That is, when the SR transmission process is triggered, the terminal 305 transmits the D-SR to the base station 310 until the SR transmission process is cancelled.
- the terminal 305 Since the terminal 305 knows the subframe allocated to its D-SR transmission resource through the control message received in step 315, the terminal 305 transmits the D-SR in the allocated subframe. . The terminal 305 repeatedly transmits the D-SR to the base station until the resource for BSR transmission is allocated. If it is assumed in step 345 that the terminal 305 has been allocated the resource for BSR transmission, in step 350 transmits the BSR to the base station 310 by using the BSR transmission resources.
- the terminal 305 When the terminal 305 transmits the BSR to the base station, the terminal 305 cancels the SR transmission process triggered in step 325 and no longer transmits the D-SR.
- the base station 310 may not be able to receive the D-SR transmitted by the terminal 305 due to some cause, such as incorrectly setting a reverse transmission power value during the D-SR transmission.
- the terminal 305 repeatedly transmits the D-SR to the base station indefinitely. In this case, problems such as increased power consumption and backward interference of the terminal 305 occur.
- the current LTE standard limits the number of D-SR transmissions of a UE to a predetermined threshold or less (dsr-transmax), and the UE sets the D-SR to the threshold value (dsr-transmax). Even after transmitting the number of times, if the base station does not receive a resource for BSR transmission, the UE stops D-SR transmission and starts a random access procedure for BSR transmission.
- the terminal transmits the D-SR to the base station by the threshold (dsr-transmax)
- the base station did not receive the reverse grant, that is, the terminal did not receive the resource for BSR transmission is the reverse of the terminal This may indicate a serious error in the transmission settings. Therefore, in this case, the terminal releases the dedicated uplink transmission resource including the D-SR transmission resource.
- the terminal transmits the D-SR to the base station by the number of times of the threshold (dsr-transmax) but fails to receive the reverse grant from the base station is referred to as "D-SR transmission failure".
- the terminal operates a predetermined counter in which a variable called SR_COUNTER is set to determine whether the D-SR transmission has failed.
- the SR_COUNTER value is initialized to zero when the SR is triggered and incremented by 1 each time the D-SR is sent.
- the UE determines that a D-SR transmission failure has occurred, releases a dedicated backward transmission resource including the D-SR transmission resource and performs a random access procedure. Perform.
- a series of operations of releasing a dedicated uplink transmission resource including a D-SR transmission resource and starting a random access process will be referred to as a "following procedure of a D-SR transmission failure".
- the terminal performs the D-SR transmission failure follow-up immediately after confirming whether the reverse grant is received after transmitting the dsr-transmax th D-SR. That is, after the terminal transmits the last D-SR and before the base station receives the last D-SR and allocates the reverse grant, the terminal performs a follow-up action of the D-SR transmission failure.
- the transmission of the last D-SR is a waste of unnecessary resources and backwards. There is a problem that causes only increased interference and waste of power of the terminal. This problem is described in more detail in FIG. 4.
- FIG. 4 is a diagram showing the problems of the prior art related to the first embodiment of the present invention.
- one rectangle represents a subframe having a size of 1 msec.
- Subframes for the D-SR transmission resources allocated to the UE are indicated by arrows 405, 410, 415, 420, 430.
- an SR transmission process is triggered at an arbitrary time point. In FIG. 4 this is indicated by reference numeral 435.
- the UE initializes SR_COUNTER to 0 in step 440 and waits until a subframe allocated for the available D-SR transmission resource.
- step 445 the UE compares SR_COUNTER with dsr-transmax, which is the maximum allowable number of transmissions of D-SR, to determine whether to perform D-SR transmission in the surf frame 410 allocated to be available as a D-SR transmission resource. If SR_COUNTER is smaller than dsr-transmax, that is, if the number of transmissions of the SR has not reached the maximum number of transmission allowances, the UE increases the SR_COUNTER by 1 in step 450 and transmits the D-SR in step 455.
- the UE repeats the operation of increasing the SR_COUNTER by 1 and comparing the SR_COUNTER and the dsr-transmax for each subframe where the D-SR transmission resource is available, and increasing the SR_COUNTER by 1 when the SR_COUNTER is small. For example, if dsr-transmax is set to 3, since the SR_COUNTER at the corresponding time is 2 in subframe 420, the SR is transmitted and the SR_COUNTER is increased by one.
- SR_COUNTER becomes 3, and this time is equal to the value of SR_COUNTER and dsr-transmax. Therefore, when the SR_COUNTER is greater than or equal to dsr-transmax, the UE performs a D-SR transmission failure subsequent procedure, that is, a D-SR transmission resource. Release and perform random access for resources for BSR transmission. That is, the subframe 420 results in the subsequent follow-up of the D-SR transmission failure even before the base station responds to the SR transmitted by the UE.
- the first embodiment of the present invention is to solve the problem described in the description of FIG. Previously, after transmitting D-SR, SR_COUNTER was increased and SR_COUNTER and dsr-transmax were compared, and when SR_COUNTER was greater than or equal to dsr-transmax, the follow-up action was performed.
- the SR_COUNTER is increased before the time of transmitting the D-SR before the predetermined time. Thereafter, SR_COUNTER is compared with dsr-transmax, and when the result of the comparison is greater than dsr-transmax, the D-SR failure follow-up is performed.
- the first embodiment of the present invention solves the above problems by changing the start time point of the D-SR failure follow-up action.
- the UE transmits the D-SR when the SR_COUNTER value and the dsr-transmax value are the same, but does not start the D-SR failure follow-up.
- the terminal increases the SR_COUNTER by 1 at a point in time before the next available subframe for the D-SR transmission resource, so that the condition that the SR_COUNTER is greater than dsr-transmax is established, and the terminal does not transmit the D-SR. D-SR failure follow-up can be performed.
- FIG. 5 is a diagram illustrating a scheduling request signal transmission operation of a terminal according to the first embodiment of the present invention.
- the UE When the SR transmission process is triggered in step 505, for example, a normal BSR occurs and the SR transmission process is triggered in step 510, the UE initializes the SR_COUNTER to zero. In step 515, the UE waits until a predetermined time point close to the available subframe for the D-SR transmission resource to determine whether to transmit the D-SR or the like.
- the predetermined time point may be set to a time point earlier than the available subframe for the D-SR transmission resource by the processing delay of the terminal required to determine whether to transmit the SR or perform a subsequent operation according to the SR transmission failure. Can be changed.
- step 520 the UE first increases SR_COUNTER by 1 before determining whether to transmit D-SR. As described above, by increasing the SR_COUNTER prior to the process of determining whether to perform D-SR transmission or follow-up on D-SR transmission failure, the UE does not transmit unnecessary D-SR before performing follow-up on D-SR transmission failure. You may not.
- the UE updates SR_COUNTER to 4 at a point in time preceding the subframe 430 and closes to the subframe 430, and compares the SR_COUNTER with dsr-transmax.
- SR_COUNTER is larger than dsr-transmax
- the UE performs subsequent operations in subframe 430. That is, instead of transmitting the last D-SR immediately after taking the next operation, the terminal waits until the available subframe time point for the D-SR transmission resource and takes the subsequent operation.
- step 525 the UE compares SR_COUNTER and dsr-transmax. If SR_COUNTER is less than or equal to dsr-transmax, the process proceeds to step 545. If SR_COUNTER is greater than dsr-transmax, the process proceeds to step 530. Step 530 is for follow-up of D-SR transmission failure and step 545 is for D-SR transmission.
- step 530 is performed. However, in the present invention, if SR_COUNTER is greater than dsr-transmax, step 530 is performed. On the other hand, if dsr-transmax is set to a value larger than that of the prior art, the conventional determination procedure may be used as it is. That is, in this case, if SR_COUNTER is less than dsr-transmax in step 525, the process proceeds to step 545. If SR_COUNTER is equal to or greater than dsr-transmax, the process may proceed to step 530. In this case, however, since the (dsr-transmax-1) th D-SR transmission is the last D-SR transmission, dsr-transmax should be set to a value larger by 1 than the conventional scheme.
- Step 530 means that the D-SR transmission has been performed up to a predetermined maximum number of times, but the terminal has not received a response, that is, a reverse grant. Therefore, the UE performs the follow-up action of the D-SR transmission failure. That is, in step 530, various dedicated uplink transmission resources including SR transmission resources are released. In step 535, a random access process is started, and in step 540, all SR transmission processes in progress are canceled.
- Step 545 means that the number of D-SR transmissions does not reach a predetermined maximum number of times, and thus the UE transmits D-SRs.
- step 550 it is checked whether the SR transmission process continues.
- the ongoing SR transmission process means that the SR transmission process is not canceled after being triggered.
- the SR transmission process may be canceled by a D-SR failure follow-up as in step 540, or may be canceled by transmitting a regular BSR.
- step 515 the UE proceeds to step 515 to continue the SR transmission process. If the SR transmission process is not in progress, that is, the SR transmission process is canceled by transmitting the BSR after the SR transmission process is triggered. If so, the terminal proceeds to step 555 to terminate the SR transmission process.
- FIG. 6 is a view illustrating a problem of the prior art related to the second embodiment of the present invention and a process of transmitting a scheduling request signal of a terminal according to the second embodiment of the present invention.
- the SR transmission process is also triggered in order to be allocated resources for regular BSR transmission.
- an exceptional situation may occur in which a D-SR is not transmitted.
- the D-SR is transmitted. If the SR is successfully transmitted and received, the UE receives a reverse grant in an arbitrary subframe in step 615. Meanwhile, in step 625, the UE performs backward transmission after four subframes from the subframe in which the reverse grant is received.
- the terminal configures a MAC PDU to be transmitted in the reverse direction when the reverse grant is received, and the MAC PDU includes a BSR.
- the MAC PDU includes a BSR.
- a new normal BSR occurs 635 between the time 620 when the configuration of the MAC PDU is completed and the time 625 when the MAC PDU of the configuration is actually transmitted.
- the new normal BSR cannot be included in the MAC PDU transmitted at the time point 625.
- the SR transmission process triggered at 605 is canceled at step 630.
- the SR transmission process for the newly generated regular BSR in step 635 is canceled without starting the D-SR transmission.
- the current LTE standard stipulates that the existing SR transmission process is canceled only when the BSR reflecting the most recent buffer state is transmitted.
- This solution is connected to the SR transmission process for the newly generated normal BSR in step 635 without canceling the SR transmission process triggered for the previous BSR in step 605 in the situation described with reference to FIG. 6. Therefore, the SR_COUNTER value is not initialized and the SR_COUNTER used in the SR transmission process of the previous step 605 for the BSR is used as it is. This may result in the D-SR transmission failure follow-up being executed too soon because the maximum number of allowable transmissions of the D-SR for the new BSR in step 635 is reduced.
- the SR transmission process (that is, the SR transmission process of step 605 in FIG. 6) being canceled is canceled at the moment of transmitting the MAC PDU in which the BSR is stored. If there is no SR transmission currently in progress even though the BSR is triggered, a new SR transmission process is triggered.
- the UE cancels the SR transmission process in progress.
- a BSR ie, BSR in step 635
- BSR BSR in step 635
- a new SR transmission process is triggered. That is, the terminal newly triggers the SR transmission process for transmission of the newly generated regular BSR after canceling the existing SR transmission process in step 630 (635).
- FIG. 7 is a diagram illustrating a scheduling request signal transmission operation of a terminal according to a second embodiment of the present invention.
- the UE triggers an SR transmission process in step 710. That is, the UE transmits the D-SR when the SR transmission resource is available and generates and transmits a MAC PDU including the BSR when the reverse grant is received and retransmits the D-SR if the reverse grant is not received. Do this.
- the UE monitors whether the BSR triggered in step 715 is canceled while performing the above operation. For example, the UE may monitor whether the triggered BSR has not been canceled for each transmission time interval (TTI). On the other hand, if the BSR reflecting the most recent buffer state after the BSR is triggered is included in the MAC PDU (for transmission), the triggered BSR process is canceled. If the triggered BSR is canceled, the operation ends.
- TTI transmission time interval
- the terminal proceeds to step 720 and checks whether there is an SR transmission process currently in progress. For reference, when the triggered BSR process is not canceled, the BSR reflecting the most recent buffer state is not yet included in the MAC PDU, or the BSR is included in the MAC PDU but the BSR reflects the current buffer state of the UE. If not, the triggered BSR is not canceled.
- step 720 if there is a SR transmission process currently in progress, the UE proceeds to step 715 and continues monitoring SR cancellation while continuing the SR transmission process. If there is no SR transmission process currently in operation 720, the UE proceeds to operation 725 to trigger a new SR transmission process. The process returns to step 715 to monitor whether the BSR is canceled. If the BSR is canceled in step 715, the terminal terminates the operation.
- FIG. 8 is a block diagram illustrating a terminal device according to the first and second embodiments of the present invention.
- the terminal apparatus includes a multiplexing and demultiplexing apparatus 805, an HARQ processor 810, an SR / BSR controller 815, a MAC controller 820, and a transceiver 825.
- the SR / BSR control unit 815 monitors whether upper layer data is generated or the like and determines whether to trigger a BSR.
- the SR / BSR controller 815 according to the first embodiment of the present invention triggers an SR transmission process and operates SR_COUNTER and dsr-transmax to perform D-SR transmission and follow-up action of D-SR transmission failure.
- the control unit 825 transmits the D-SR or performs a random access operation according to the determination result.
- the SR / BSR controller 815 determines whether to cancel the BSR, and triggers a new SR transmission process if there is no SR transmission process in progress even though there is a BSR that has not been cancelled.
- the MAC controller 820 interprets scheduling information received through the forward and reverse control channels and controls the transceiver 825 to receive forward data or transmit reverse data.
- the multiplexing and demultiplexing apparatus 805 controls to generate data to be transmitted in the reverse direction.
- the SR / BSR controller 815 notifies the SR / BSR controller 815 when the reverse grant is received so that the SR / BSR controller 815 can determine the cancellation of the SR transmission process and the BSR cancellation.
