Method and Apparatus for Sidelink Resource Selection

A method performed by a transmitting (TX) user equipment (UE), the method comprising:

• obtaining at least one Discontinuous Reception (DRX) active time of at least one receiving (RX) UE;
• selecting one or more resources to create a sidelink (SL) grant based on the at least one DRX active time of the at least one RX UE;
• and
• selecting a destination based on the at least one DRX active time of at least one RX UE and at least one resource in a created SL grant,
• wherein a destination is associated with a single or multiple RX UEs,
• wherein selecting one or more resources to create a SL grant based on the at least one DRX active time of the at least one RX UE comprises:
• determining whether one or more available resources for creating the SL grant for data transmission fulfills at least one first condition, wherein the at least one first condition comprises:
• an overlapping in a time domain occurs between the at least one DRX active time of at least one RX UE and the one or more available resources identified by a resource identification procedure,
• selecting the one or more resources for creating a SL grant for data transmission from the one or more available resources identified by a resource identification procedure, based on the at least one DRX active time of the at least one RX UE.

A transmitting (TX) user equipment (UE) comprising:

• a processor;
• and
• a memory coupled to the processor, said memory containing instructions executable by said processor, whereby said TX UE is operative to:
• obtain at least one Discontinuous Reception (DRX) active time of at least one receiving (RX) UE;
• select one or more resources to create a sidelink (SL) grant based on the at least one DRX active time of the at least one RX UE, and
• select a destination based on the at least one DRX active time of at least one RX UE and at least one resource in a created SL grant,
• wherein a destination is associated with a single or multiple RX UEs,
• wherein select one or more resources to create a SL grant based on the at least one DRX active time of the at least one RX UE comprises:
• determine whether one or more available resources for creating the SL grant for data transmission fulfills at least one first condition, wherein the at least one first condition comprises:
• an overlapping in a time domain occurs between the at least one DRX active time of at least one RX UE and the one or more available resources identified by a resource identification procedure,
• select the one or more resources for creating a SL grant for data transmission from the one or more available resources identified by a resource identification procedure, based on the at least one DRX active time of the at least one RX UE.
