Abstract: A method and apparatus for handling BWP switching based on priority in a wireless communication system is provided. A wireless device receives configuration of multiple bandwidth parts (BWPs) on a cell, wherein the multiple BWPs includes at least one active uplink (UL) BWP for UL transmission and at least one active sidelink (SL) BWP for SL transmission. A wireless device detects a triggering condition for switching to a specific UL BWP which cannot be simultaneously active with the active SL BWP. A wireless device determines whether to switch to the specific UL BWP based on priority information, wherein the priority information includes at least one of UL priority and/or SL priority. A wireless device performs the switching to the specific UL BWP based on the determination.

Abstract: The present disclosure relates to transmission prioritization in wireless communications. According to an embodiment of the present disclosure, a method performed by a wireless device in a wireless communication system comprises: receiving, from a network, information for a threshold related to a buffer status report (BSR); prioritizing a logical channel group (LCG) for the BSR based on the threshold, wherein a highest priority of one or more logical channels having data available for transmission in the LCG is lower than the threshold; prioritizing the BSR based on the prioritized LCG; creating a media access control (MAC) protocol data unit (PDU) comprising at least the prioritized BSR; and transmitting the MAC PDU.

Abstract: Based on an embodiment of the present disclosure, provided is a method for performing sidelink communication by a first device. The method may comprise: receiving, from a second device, a CSI-RS; transmitting, to a base station, a SR or a BSR, based on triggering of sidelink CSI MAC CE transmission to the second device by channel-related information measured based on the CSI-RS; receiving, from the base station, a sidelink grant related to the SR or the BSR; and canceling the triggered sidelink CSI MAC CE transmission to the second device, based on a latency bound related to the sidelink CSI MAC CE transmission and a time period based on the sidelink grant for the sidelink CSI MAC CE transmission.
