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.

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: Methods and apparatuses for handling discontinuous reception and partial sensing for sidelink communication to reduce potential latency due to additional sensing, and to improve resource utilization efficiency. A first device can perform sidelink communication to at least a second device, or a second device in a sidelink resource pool, and trigger to perform resource selection for a sidelink data at a timing. The first device can perform sensing for a first contiguous sensing duration before a sidelink on-duration active time of the second device, determine or select a first sidelink resource from a set of sidelink resources, derive or determine the set of sidelink resources based on at least a sensing result in the first contiguous sensing duration, and perform a first sidelink transmission on the first sidelink resource for transmitting the sidelink data to the second device.

Abstract: A method and apparatus are disclosed from the perspective of a device to perform sidelink communication. In one embodiment, the method includes the device receiving a sidelink grant from a network node, wherein the sidelink grant schedules or assigns multiple sidelink resources. The method further includes the device generating a data packet comprising or multiplexing sidelink data from Sidelink (SL) logical channel(s) with SL Hybrid Automatic Request (HARQ) feedback enabled. The method further includes the device performing two sidelink transmissions for the data packet on two adjacent, neighbor, or consecutive sidelink resources among the multiple sidelink resources if a time gap of the two adjacent, neighbor, or consecutive sidelink resources is larger than or equal to a minimum time gap. In addition, the method includes the device being allowed to drop, skip, or cancel a sidelink transmission on one sidelink resource of the two adjacent, neighbor, or consecutive sidelink resources among the multiple sidelink resources if the time gap of the two adjacent, neighbor, or consecutive sidelink resources is less than a minimum time gap.

In one embodiment, the first device has a configuration of the sidelink resource pool, wherein the sidelink resource pool is enabled with resource reservation for different Transport Blocks (TBs). The first device also has a configuration of a list of reserved periods. Furthermore, the first device selects or determines a first reserved period from the list of reserved periods, wherein the first selected or determined reserved period is within a first set of reserved periods. In addition, the first device randomly selects a first integer in a first interval, wherein the first interval is based on a scaling factor and a second interval, and the scaling factor is derived based on a largest reserved period in the first set of reserved periods, and wherein the first integer indicates a number of transmission opportunities of different TBs with the first reserved period. The first device further performs sidelink transmission of one TB on one transmission opportunity from the number of transmission opportunities.
