Abstract: A method and apparatus for media access control (MAC) reset for radio resource control (RRC) connection between wireless devices is provided. A wireless device operating in a wireless communication system triggers a scheduling request (SR) based on a triggered sidelink (SL) buffer status report (BSR) and/or SL channel state information (CSI) reporting. Based on a media access control (MAC) reset being requested, by an upper layer of the wireless device, for one PC5-RRC connection among one or more PC5-RRC connections, the wireless device cancels any SR only associated to the one PC5-RRC connection.

Abstract: A method and apparatus for hybrid automatic repeat request (HARQ) transmissions for configured grants (CGs) in a wireless communication system is provided. A first wireless device receives a retransmission resource for a HARQ process identifier (ID) for a CG. When a number of transmissions of a media access control (MAC) protocol data unit (PDU) does not reach to a maximum number of transmissions, the first wireless device performs retransmission of the MAC PDU to a second wireless device by using the retransmission resource. When the number of transmissions of the MAC PDU reaches to the maximum number of transmissions, the first wireless device flushes a HARQ buffer in a sidelink process.

Abstract: A method and apparatus for indicating sidelink (SL) radio link failure (RLF) in a wireless communication system is provided. A first wireless device may initialize the counter to zero upon 1) establishing the PC5-RRC connection with the second wireless device, or 2) configuring or reconfiguring the maximum number of the counter. A first wireless device may increase the counter based on no reception of any acknowledgement to the transmission of the MAC PDU. A first wireless device may indicate Sidelink (SL) Radio Link Failure (RLF) for the PC5-RRC connection based on that the counter reaches the maximum number of the counter.

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: According to an embodiment of the present disclosure, provided is a method by which a first apparatus performs sidelink communication. The method may comprise the steps of: transmitting a first transport block to a second apparatus, on a resource allocated by a first SL grant received from a base station; transmitting, to the base station, a system information request message requesting system information; transmitting, on an exceptional resource pool, a second transport block to the second apparatus, on the basis of the transmission of the system information request message to the base station; and receiving, from the base station, first system information related to the system information request message.
