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.
