Abstract
A method and information processing system for wirelessly transmitting at least one of a downlink channel descriptor and an uplink channel descriptor for reception by at least one wireless device (104). The method comprises selecting at least one transmission time for transmitting a pointer that indicates a transmission time for a DCD and/or a UCD. The pointer is transmitted at a time between a first transmission and a second transmission of the at least one of downlink channel descriptor and uplink channel descriptor. The transmission time is selected to reduce a time interval for the at least one wireless device (104) to search for the at least one of the DCD and UCD. Also, a message that includes DCD information and/or UCD information associated with at least one neighboring cell can also be chosen to transmit at specifically chosen times to the at least one wireless device (104).
Claims
1. /v mexnoα, witn a wireless communication system, for wireJessly transmitting at least one of a downlink channel descriptor and an uplink channel descriptor for reception by at least one wireless device, the method comprising: selecting at least one transmission time for transmitting, for reception by at least one wireless device, at least one of:
a pointer indicating a transmission time for at least one of a downlink channel descriptor and an uplink channel descriptor, wherein the pointer is transmitted at a time, between a first transmission and a second transmission of the at least one of downlink channel descriptor and uplink channel descriptor, selected to reduce a time interval for the at least one wireless device to search for the at least one of the downlink channel descriptor and uplink channel descriptor; and a message including downlink channel descriptor information and uplink channel descriptor information associated with at least one neighboring cell, wherein the message is transmitted during the time between the first transmission and the second transmission of the at least one of downlink channel descriptor and uplink channel descriptor.
2. The method of claim 1, wherein the time between the first transmission and the second transmission of the at least one of downlink channel descriptor and uplink channel
descriptor corresponds to a paging listening interval associated with a home paging group.
i
3. The method of claim 1, wherein choosing specific transmission time of the message further comprises: transmitting the message during a paging listening interval associated with a home paging group.
4. The method of claim 1, wherein the message is transmitted between the first transmission and the second transmission of the at least one of downlink channel descriptor and uplink channel descriptor, at substantially any of the following times: a 1/3 point in time between the first transmission and the second transmission of the at least one of downlink channel descriptor and uplink channel descriptor; a mid-point in time therebetween; and a 2/3 point in time therebetween.
5. The method of claim 1 , further comprising: determining at least one of offset parameters and cycle parameters for at least one neighboring paging group.
6. A method, with a wireless device, for receiving at least one of a downlink channel descriptor and an uplink channel descriptor, the method comprising, receiving a pointer indicating a transmission time of at least one of a downlink channel descriptor and an uplink channel descriptor; ceasing to monitor for the at least one of the downlink channel descriptor and uplink channel descriptor in response to receiving the pointer; determining if the transmission time for the least one of the downlink channel descriptor and the uplink channel descriptor has occurred; monitoring, in response to the transmission time being determined to have occurred, for reception of the at least one of the downlink channel descriptor and the uplink channel descriptor; determining, in response to receiving the at least one of the downlink channel descriptor and the uplink channel descriptor, a new time interval between transmissions of the at least one of the downlink channel descriptor and the uplink channel descriptor; and receiving a message including at least one of a downlink channel descriptor and uplink channel descriptor information at a time of transmission of the at least one of the downlink channel descriptor and the uplink channel descriptor associated with a neighboring paging group.
7. A method, with a wireless device, for receiving at least one of a downlink channel descriptor and an uplink channel descriptor, the method comprising, receiving a pointer indicating a transmission time of at least one of a downlink channel descriptor and an uplink channel descriptor; ceasing to monitor for the at least one of the downlink channel descriptor and uplink channel descriptor in response to receiving the pointer; determining if the transmission time for the least one of the downlink channel descriptor and the uplink channel descriptor has occurred; monitoring, in response to the transmission time being determined to have occurred, for reception of the at least one of the downlink channel descriptor and the uplink channel descriptor; determining, in response to receiving the at least one of the downlink channel descriptor and the uplink channel descriptor, a new time interval between transmissions of the at least one of the downlink channel descriptor and the uplink channel descriptor; and entering into at least one neighboring cell; determining, based on the channel descriptor and uplink channel descriptor information received in the message, that a location update function needs to be performed; and performing the location update function in response to the determination.
8. An information processing system in a wireless communication system for wirelessly transmitting at least one of a downlink channel descriptor and an uplink channel descriptor for reception by at least one wireless device, the information processing system comprising: at least one processing unit; a memory communicatively coupled to the at least one processing unit; and a transmitter communicatively coupled to the memory and the at least one processing unit, the transmitter for selecting at least one transmission time, whereupon the transmitter transmits, for reception by at least one wireless device, at least one of: a pointer indicating a transmission time for at least one of a downlink channel descriptor and an uplink channel descriptor, wherein the pointer is transmitted at a time, between a first transmission and a second transmission of the at least one of downlink channel descriptor and uplink channel descriptor, selected to reduce a time interval for the at least one wireless device to search for the at least one of the downlink channel descriptor and uplink channel descriptor; and a message including downlink channel descriptor information and uplink channel descriptor information associated with at least one neighboring cell, wherein the message is transmitted during the time between the first transmission and the second transmission of the at least one of downlink channel descriptor and uplink channel descriptor.
9. The information processing system of claim 8, wherein the transmitter transmits the pointer during a paging listening interval associated with a home paging group.
10. The information processing system of claim 8, wherein the transmitter transmits the message during a paging listening interval associated with at least one neighboring paging group.
