Abstract: A method and apparatus are disclosed for a device to perform sidelink communication. The device triggers or requests to perform partial sensing-based resource selection in a first Transmission Time Interval (TTI) in a sidelink resource pool. The device also derives or determines a set of candidate TTIs within a resource selection window in response to the trigger or request, wherein sidelink resources in the set of candidate TTIs are candidate sidelink resources. Furthermore, when the device does not perform sensing in a second TTI, the device excludes a number of candidate sidelink resources, from the candidate sidelink resources, associated with the second TTI, wherein the second TTI is after the first TTI and before the first candidate TTI of the set of candidate TTIs. The device further derives or determines a set of sidelink resources, from the candidate sidelink resources at least excluding the number of candidate sidelink resources.

In an example from the perspective of a first device, the first device performs sidelink communication with a first set of destinations, wherein one or more devices, associated with a destination of the first set of destinations, discontinuously monitor one or more sidelink control channels and/or one or more sidelink control informations (SCIs). The first device receives a sidelink grant from a network, wherein the sidelink grant is for performing a sidelink transmission at a first timing. The first device selects, from among a second set of destinations, a first destination for the sidelink transmission, wherein each destination of the second set of destinations is determined to have an active time for sidelink containing the first timing.

Abstract: Methods and apparatuses for handling partial sensing and discontinuous reception for sidelink communication to reduce potential latency due to additional sensing and to improve resource utilization efficiency. Various embodiments can comprise a first device performing sidelink communication to at least a second device, or a second device in a sidelink resource pool, and triggering to perform resource selection for a sidelink data at a timing, wherein the first device (already) receives or monitors sidelink control information for a (contiguous) time duration before the timing. The first device can perform sensing for a contiguous sensing duration after the timing, determine or select a first sidelink resource from a set of sidelink resources, and perform a first sidelink transmission on the first sidelink resource for transmitting the sidelink data to the second device.

Abstract: In an example, a second UE receives a first SCI and a second SCI from a first UE in a first slot. A groupcast sidelink transmission is scheduled by the first SCI and the second SCI. The second SCI indicates a location indication, associated with a location of the first UE, and a communication range. A PSFCH resource is determined based upon the first SCI. The second UE doesn't transmit a NACK indication on the PSFCH resource if location information of the second UE is available, the groupcast sidelink transmission isn't successfully decoded, and the second UE is outside the communication range. The second UE transmits the NACK indication on the PSFCH resource if the location information isn't available and the groupcast sidelink transmission isn't successfully decoded, or if the location information is available, the groupcast sidelink transmission isn't successfully decoded, and the second UE is within the communication range.

Abstract: In an example, a device receives a first sidelink control information in a first sidelink Transmission Time Interval (TTI) in a sidelink resource pool. The first sidelink control information is indicative of a first sidelink resource in a second sidelink TTI. The device determines a conflict associated with the first sidelink resource. The device determines a transmission occasion for a first sidelink transmission with conflict information. The device determines a plurality of sidelink transmissions in the transmission occasion. The plurality of sidelink transmissions comprises a first set of sidelink transmissions with conflict information, and/or a second set of sidelink transmissions with sidelink Hybrid Automatic Repeat Request (HARQ) feedback. The first set of sidelink transmissions comprise the first sidelink transmission. The device determines one or more sidelink transmissions of the plurality of the sidelink transmissions. Determining the one or more sidelink transmissions may comprise prioritizing the second set of sidelink transmissions with HARQ feedback over the first set of sidelink transmissions with conflict information. The device performs the one or more sidelink transmissions in the transmission occasion.
