Abstract: A method and apparatus for allocation of lower identifier (ID) and upper identifier (ID) for sidelink transmission in a wireless communication system is provided. A first wireless device (e.g., receiving user equipment (UE)) receives, via upper layer signaling from a second wireless device (e.g., transmitting UE), a lower ID associated with an upper ID and monitors sidelink control information (SCI) based on the lower ID and the upper ID. The first wireless device receives, from the second wireless device, a data unit scheduled by the SCI.

Abstract: A user equipment (UE) receives, from a network, a semi-persistent scheduling (SPS) configuration and a physical uplink control channel (PUCCH) resource configuration. The PUCCH resource configuration may be included in the SPS configuration. When a change of an SPS operation is required, the user equipment transmits an SPS change request to the network and receives, from the network, an SPS resource grant activated according to the SPS change request. The user equipment changes allocation of a PUCCH resource allocated according to the PUCCH resource configuration, on the basis of the received SPS resource grant. For example, a timing at which or a period in which the PUCCH resource is allocated can be changed.

Abstract: A method and apparatus for dynamic configuration of a maximum number of sidelink retransmissions for a data unit in a wireless communication system is provided. A first wireless device in sidelink receives, from a network, information related to a first retransmission number for a first logical channel and a second retransmission number for a second logical channel. The first wireless device determines a retransmission number of a data unit among the first retransmission number and the second retransmission number, and performs sidelink transmission of the data unit to a second wireless device based on the retransmission number of the data unit.
