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: A method and apparatus for managing SCells during a conditional PCell handover in a wireless communication system is provided. A wireless device receives, from the source PCell, a handover command including a PCell condition for a target PCell. The handover command includes at least one of Secondary Cell (SCell) conditions for target SCells. A wireless device evaluates the SCell conditions for the target SCells upon determining that the PCell condition for the target PCell is met. A wireless device transmits, to the target PCell, a handover complete message including result of the evaluation of the SCell conditions for the target SCells.
