Abstract
A method and apparatus for Sidelink (SL) Discontinuous Reception (DRX) operation based on multiple DRX configurations and prioritization is provided. A third wireless device receives, from a first wireless device, first Sidelink (SL) Discontinuous Reception (DRX) information, and receives, from a second wireless device, second SL DRX information. The third wireless device informs a network about the first and second SL DRX information, each of which is constructed for each pair of source and destination.
Claims13
A method performed by a third wireless device adapted to operate in a wireless communication system, the method comprising:
- establishing a first PC5-Radio Resource Control (RRC) connection with a first wireless device, wherein the first PC5-RRC connection is a logical connection between the first wireless device and the third wireless device for a first pair of source and destination;
- establishing a second PC5-RRC connection with a second wireless device, wherein the second PC5-RRC connection is a logical connection between the second wireless device and the third wireless device for a second pair of source and destination;
- receiving, from the first wireless device, a first Sidelink (SL) Discontinuous Reception (DRX) configuration;
- receiving, from the second wireless device, a second SL DRX configuration;
- and
- transmitting, to a network, an RRC message including the first SL DRX configuration and the second SL DRX configuration,
- wherein each of the first SL DRX configuration and the second SL DRX configuration is constructed for each destination in the RRC message.
A third wireless device adapted to operate in a wireless communication system, the third wireless device comprising:
- at least one transceiver;
- at least one processor;
- and
- at least one memory operably connectable to the at least one processor and storing instructions that, based on being executed by the at least one processor, perform operations comprising:
- establishing a first PC5-Radio Resource Control (RRC) connection with a first wireless device, wherein the first PC5-RRC connection is a logical connection between the first wireless device and the third wireless device for a first pair of source and destination;
- establishing a second PC5-RRC connection with a second wireless device, wherein the second PC5-RRC connection is a logical connection between the second wireless device and the third wireless device for a second pair of source and destination;
- receiving, from the first wireless device via the at least one transceiver, a first Sidelink (SL) Discontinuous Reception (DRX) configuration;
- receiving, from the second wireless device via the at least one transceiver, a second SL DRX configuration;
- and
- transmitting, to a network via the at least one transceiver, an RRC message including the first SL DRX configuration and the second SL DRX configuration,
- wherein each of the first SL DRX configuration and the second SL DRX configuration is constructed for each destination in the RRC message.
A base station adapted to operate in a wireless communication system, the base station comprising:
- at least one transceiver;
- at least one processor;
- and
- at least one memory operably connectable to the at least one processor and storing instructions that, based on being executed by the at least one processor, perform operations comprising:
- transmitting, via the at least one transceiver, system information;
- and
- receiving, from a third wireless device via the at least one transceiver, a radio resource control (RRC) message including a first Sidelink (SL) Discontinuous Reception (DRX) configuration and a second SL DRX configuration,
- wherein each of the first SL DRX configuration and the second SL DRX configuration is constructed for each destination in the RRC message,
- wherein the first SL DRX configuration is provided from a first wireless device to the third wireless device,
- wherein a first PC5-Radio Resource Control (RRC) connection is established between the first wireless device and the third wireless device for a first pair of source and destination,
- wherein the second SL DRX configuration is provided from a second wireless device to the third wireless device, and
- wherein a second PC5-RRC connection is established between the second wireless device and the third wireless device for a second pair of source and destination.
