Extended Contiguous Sensing during Sidelink Discontinuous Reception (SL-DRX)

A method performed by a user equipment (UE) configured for sidelink (SL) communication with one or more other UEs in a wireless network, the method comprising:

• while operating in SL discontinuous reception (SL-DRX) comprising a plurality of active times during which the UE's SL receiver is active and a plurality of inactive times during which the UE's SL receiver is inactive, receiving, at a time n, a trigger to select resources for a SL transmission;
• extending a contiguous partial sensing (CPS) window after the trigger at time n when a portion of an active time is less than a first duration, wherein:
• the portion of the active time corresponds to an overlap of the active time with a remaining packet delay budget (PDB) associated with the SL transmission, and
• the first duration comprises a minimum contiguous partial sensing window (CPSWmin) followed by a minimum resource selection window (RSWmin);
• and
• performing at least one of the following during the portion of the active time:
• CPS of resources;
• and selection of resources for the SL transmission.

A user equipment (UE) configured for sidelink (SL) communication with one or more other UEs in a wireless network, the UE comprising:

• communication interface circuitry configured to communicate via SL with other UEs and with the wireless network, wherein the communication interface circuitry include a SL receiver;
• and
• processing circuitry operably coupled to the communication interface circuitry, whereby the processing circuitry and the communication interface circuitry are configured to:
• while operating in SL discontinuous reception (SL-DRX) comprising a plurality of active times during which the SL receiver is active and a plurality of inactive times during which the SL receiver is inactive, receive, at a time n, a trigger to select resources for a SL transmission;
• extend a contiguous partial sensing (CPS) window after the trigger at time n when a portion of an active time is less than a first duration, wherein:
• the portion of the active time corresponds to an overlap of the active time with a remaining packet delay budget (PDB) associated with the SL transmission, and
• the first duration comprises a minimum contiguous partial sensing window (CPSWmin) followed by a minimum resource selection window (RSWmin);
• and
• perform at least one of the following during the portion of the active time:
• contiguous partial sensing (CPS) of resources;
• and selection of resources for the SL transmission.

A non-transitory, computer-readable medium storing computer-executable instructions that, when executed by processing circuitry of a user equipment (UE) configured for sidelink (SL) communication with one or more other UEs in a wireless network, configure the UE to:

• while operating in SL discontinuous reception (SL-DRX) comprising a plurality of active times during which the UE's SL receiver is active and a plurality of inactive times during which the UE's SL receiver is inactive, receive at a time n a trigger to select resources for a SL transmission;
• extend a contiguous partial sensing (CPS) window after the trigger at time n when a portion of an active time is less than a first duration, wherein:
• the portion of the active time corresponds to an overlap of the active time with a remaining packet delay budget (PDB) associated with the SL transmission, and
• the first duration comprises a minimum contiguous partial sensing window (CPSWmin) followed by a minimum resource selection window (RSWmin);
• and
• perform at least one of the following during the portion of the active time:
• CPS of resources;
• and selection of resources for the SL transmission.
