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.

Abstract: A method and apparatus are disclosed from the perspective of a first device. In one embodiment, the method includes the first device receiving a configuration, from a network node, of a first sidelink resource pool without any Physical Sidelink Feedback Channel (PSFCH) resource. The method further includes the first device receiving a first sidelink grant transmitted, configured, or scheduled by the network node, wherein the first sidelink grant schedules or indicates at least a first sidelink resource in the first sidelink resource pool. Furthermore, the method includes the first device expecting or considering that the first sidelink grant provides no Physical Uplink Control Channel (PUCCH) resource for reporting Sidelink (SL) Hybrid Automatic Repeat Request (HARD) feedback.

Abstract: A method and apparatus are disclosed from the perspective of an User Equipment (UE). In one embodiment, the method includes the UE deriving a first pathloss value from a first pathloss reference of a serving cell, wherein the first pathloss value is used for deriving a power headroom value included in a first power headroom report. The method also includes the UE deriving a second pathloss value from a second pathloss reference of the serving cell after deriving the first pathloss value, wherein the second pathloss reference is used for power control for a first Physical Uplink Shared Channel (PUSCH) transmission on the serving cell. The method further includes the UE deriving the pathloss change based on the first pathloss value and the second pathloss value. In addition, the method includes the UE determining whether a second power headroom report is triggered based on whether the pathloss change is more than a threshold.
