Abstract
A discontinuous reception (DRX) parameter configuration method includes a first communication apparatus that sends data to a second communication apparatus on a sidelink based on a DRX parameter. The second communication apparatus determines an active time and a sleep period of the second communication apparatus based on the DRX parameter, and receives the data in the active time.
Claims20
A sidelink discontinuous reception (DRX) parameter configuration method implemented by a first communication apparatus, wherein the sidelink DRX parameter configuration method is applied to a device-to-device (D2D) communication scenario, and wherein the sidelink DRX parameter configuration method comprises:
- obtaining a sidelink DRX parameter, wherein the sidelink DRX parameter is used by the first communication apparatus to send data, on a sidelink based on the sidelink DRX parameter, to at least one second communication apparatus connected to the first communication apparatus;
- sending, to the at least one second communication apparatus, the sidelink DRX parameter;
- receiving sidelink resource information;
- determining based on the sidelink DRX parameter, the sidelink resource information, and a logical channel priority, a third communication apparatus in an active time of sidelink, which is one of the at least one second communication apparatus;
- and
- performing, based on the sidelink resource information, communication with the third communication apparatus.
A sidelink discontinuous reception (DRX) parameter configuration method implemented by a network device, wherein the sidelink DRX parameter configuration method is applied to a device-to-device (D2D) communication scenario, and wherein the sidelink DRX parameter configuration method comprises:
- determining a sidelink DRX parameter, wherein the sidelink DRX parameter is used by a first communication apparatus to send data, on a sidelink based on the sidelink DRX parameter, to at least one second communication apparatus connected to the first communication apparatus;
- sending, to the first communication apparatus, the sidelink DRX parameter;
- and
- sending, to the first communication apparatus, sidelink resource information,
- wherein the sidelink resource information enables the first communication apparatus based on the sidelink DRX parameter, the sidelink resource information, and a logical channel priority, to determine a third communication apparatus that is in an active time of sidelink, which is one of the at least one second communication apparatus and to perform communication with the third communication apparatus based on the sidelink resource information.
A first communication apparatus applied to a device-to-device (D2D) communication scenario and comprising:
- a memory configured to store instructions;
- and
- a processor coupled to the memory and configured to execute the instructions to cause the first communication apparatus to:
- obtain a sidelink discontinuous reception (DRX) parameter, wherein the sidelink DRX parameter is used by the first communication apparatus to send data, on a sidelink based on the sidelink DRX parameter, to at least one second communication apparatus connected to the first communication apparatus;
- send, to the at least one second communication apparatus, the sidelink DRX parameter;
- receive sidelink resource information;
- determine, based on the sidelink DRX parameter the sidelink resource information, and a logical channel priority, a third communication apparatus in an active time of sidelink, which is one of the at least one second communication apparatus;
- and
- perform, based on the sidelink resource information, communication with the third communication apparatus.
