Abstract: A method and apparatus for triggering of transmission carrier or resource reselection in a wireless communication system is provided. A first wireless device reserves a set of resources comprising at least a first resource and a second resource for sidelink transmission. When (i) the sidelink transmission using the first resource overlaps with an uplink transmission, and (ii) a priority of the uplink transmission is higher than a threshold, the first wireless device clears the first resource from the set of resources, and adds a third resource to the set of resources.

Abstract: A method and apparatus for logical channel prioritization (LCP) based on hybrid automatic repeat request (HARQ) feedback in a wireless communication system is provided. A wireless device selects a first logical channel with a highest priority among multiple logical channels having data available for transmission. When the first logical channel is configured with a hybrid automatic repeat request (HARQ) feedback, the wireless device selects one or more second logical channels configured with the HARQ feedback among the multiple logical channels. When the first logical channel is not configured with HARQ feedback, the wireless device selects one or more second logical channels not configured with the HARQ feedback among the multiple logical channels. The wireless device creates a data unit based on the first logical channel and the one or more second logical channels.

Abstract: A method and apparatus for transmission based on QoS requirement in a wireless communication system is provided. A wireless device sets a priority level of a logical channel. A wireless device detects that Quality of Service (QoS) requirement of the logical channel is not met. A wireless device de-prioritizes the priority level of the logical channel. A wireless device performs the SL transmission and/or the UL transmission for the logical channel with the de-prioritized priority level.

Abstract: The present disclosure relates to channel state reporting in wireless communications. According to an embodiment of the present disclosure, a method performed by a first wireless device in a wireless communication system comprises: establishing a PC5 radio resource control (RRC) connection between the first wireless device and a second wireless device; receiving sidelink control information (SCI) from the second wireless device, wherein the SCI instructs the first wireless device to perform sidelink (SL)-channel state information (CSI) reporting for the PC5 RRC connection; triggering the SL-CSI reporting; and based on that a sidelink resource for the SL-CSI reporting is unavailable and the first wireless device is configured with a mode in which sidelink resources are scheduled by a network, transmitting a signal related to the SL CSI reporting for requesting the sidelink resource to the network.
