Abstract: A method and apparatus are disclosed from the perspective of a first device for performing sidelink transmission in a sidelink resource pool. 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.

Abstract: Methods and apparatuses for handling collision between sidelink feedback and sidelink data in a wireless communication system are disclosed herein. In one method, a User Equipment (UE) is (pre-)configured to perform one or more sidelink transmissions on multiple carriers, wherein the UE is able to transmit a first number of carriers among the multiple carriers at the same time. The UE selects a first resource for transmitting a first sidelink transmission in a first slot on a first carrier. The UE derives a second resource for transmitting a PSFCH delivering a feedback in a second slot on a second carrier, wherein the second slot is at least partly overlapping with the first slot in a time domain. The UE determines whether to prioritize either the PSFCH or the first sidelink transmission based on a rule when the number of carriers which the UE identifies to transmit in the overlapped slot exceeds the first number of carriers.

Abstract: A method and apparatus are disclosed. In an example, a first device receives a configuration and/or an information, wherein the configuration and/or the information is indicative of a DRX pattern, of the second device, associated with monitoring the sidelink resource pool. The first device transmits a signal to at least the second device on a first opportunity of a plurality of opportunities, wherein the signal indicates the second device to perform monitoring and/or sensing for a first duration. The first device selects a first candidate resource in the sidelink resource pool, wherein the first candidate resource is in a sleep time of the DRX pattern of the second device. The first device transmits a first sidelink transmission, including a sidelink data and/or a sidelink traffic, on the first candidate resource to the second device.
