Abstract
A control entity in a wireless communications system obtains discontinuous reception information for a plurality of wireless terminals and configures one or more of said wireless terminals, based on the obtained discontinuous reception information, to harmonise the awake periods of the plurality of wireless terminals. The control entity determines a common reception period for the plurality of wireless terminals such that a broadcast or multicast transmission during the common reception period is received simultaneously by the wireless terminals.
Claims29
A method for managing discontinuous reception operation in a communications system wherein the communications system comprises a plurality of wireless terminals each supporting a discontinuous reception operation wherein each wireless terminal discontinuously receives data transmissions, the method comprising:
- obtaining discontinuous reception information for each of said wireless terminals wherein the discontinuous reception information comprises one or more of:
- a reception period, a sleep period, a DRX cycle, and a DRX cycle start period;
- an
- generating, based on the obtained discontinuous reception information, a discontinuous reception configuration for one or more of said wireless terminals to produce a common reception period, wherein the common reception period is a period during which the plurality of wireless terminals are able to receive a data transmission at the same time;
- and the discontinuous reception configuration comprises modifying one or more of the reception period, the sleep period, the DRX cycle, and the DRX cycle start period;
- and
- signalling the discontinuous reception configuration for the one or more wireless terminals to produce the common reception period.
(canceled)
A control entity for use in a communications system wherein the communications system comprises a plurality of wireless terminals each supporting a discontinuous reception operation wherein each wireless terminal discontinuously receives data transmissions, wherein the control entity is configured to:
- obtain discontinuous reception information for each of said wireless terminals wherein the discontinuous reception information comprises one or more of a reception period, a sleep period, a DRX cycle, and a DRX cycle start period;
- generate, based on the obtained discontinuous reception information, a discontinuous reception configuration for one or more of said wireless terminals to produce a common reception period, wherein the common reception period is a period during which the plurality of wireless terminals are able to receive a data transmission at the same time and the discontinuous reception configuration comprises modifying one or more of the reception period, the sleep period, the DRX cycle, and the DRX cycle start period and
- signal the discontinuous reception configuration for the one or more wireless terminals to produce the common reception period.
(canceled)
A method of discontinuous reception operation in a wireless terminal in a communications system, wherein the communications system comprises a plurality of wireless terminals, the method comprising:
- reporting discontinuous reception information, wherein the discontinuous reception information comprises one or more of:
- a reception period, a sleep period, a DRX cycle, and a DRX cycle start period;
- receiving a discontinuous reception configuration wherein the discontinuous reception configuration produces a common reception period for the plurality of wireless terminals and the discontinuous reception configuration comprises modifying one or more of the reception period, the sleep period, the DRX cycle, and the DRX cycle start period;
- and
- adapting the discontinuous reception operation based on the received discontinuous reception configuration.
(canceled)
A wireless terminal for use in a communications system, wherein the communications system comprises of a plurality of wireless terminals, wherein the wireless terminal is configured to support a discontinuous reception operation, the wireless terminal is further configured to:
- report discontinuous reception information, wherein the discontinuous reception information comprises one or more of:
- a reception period, a sleep period, a DRX cycle, and a DRX cycle start period;
- receive a discontinuous reception configuration wherein the discontinuous reception configuration produces a common reception period for the plurality of wireless terminals and the discontinuous reception configuration comprises modifying one or more of the reception period, the sleep period, the DRX cycle, and the DRX cycle start period;
- and
- adapt the discontinuous reception operation based on the received discontinuous reception configuration.
