Abstract: A method and apparatus for Sidelink (SL) Discontinuous Reception (DRX) operation based on resource allocation is provided. A first wireless device, e.g., receiving user equipment (RX UE), monitors first Physical Sidelink Control Channel (PSCCH) transmissions from a second wireless device, e.g., transmitting UE (TX UE), in a Sidelink (SL) active time for SL Discontinuous Reception (DRX). The first wireless device receives, from the second wireless device, an indication to reselection of sidelink resources, and adjusts the SL active time based on the indication. The first wireless device monitors second PSCCH transmissions from the second wireless device in the adjusted SL active time.

Abstract: A method and apparatus for triggering a transmission carrier reselection procedure for deactivated duplication in a wireless communication is provided. A wireless device selects a first carrier carrying a data unit, and selects a second carrier carrying a duplication of the data unit based on activation of the duplication of the data unit. The wireless device triggers a carrier reselection procedure based on deactivation of the duplication of the data unit.

Abstract: Provided are a method for a user equipment (UE) to transmit a medium access control protocol data unit (MAC PDU) in a wireless communication system, and an apparatus supporting the same. The method may include: receiving information on priorities of semi persistent scheduling (SPS) configurations, from a base station; selecting a first carrier among the multiple carriers, based on the information on priorities of the SPS configurations; allocating a resource of the selected first carrier to a logical channel with the highest priority; and transmitting the MAC PDU, by using the resource of the selected first carrier.

Abstract: A method of operating a first apparatus 100 in a wireless communication system is proposed. The method may include: receiving a value related to priority of first data and the first data from a second apparatus 200; determining data to be transmitted based on a first resource, by comparing a threshold related to relay communication and the value related to the priority of the first data; and transmitting the determined data to a base station 300.

Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for transmitting assistance information to a network/base station when a condition is satisfied. Whether the condition is satisfied or not is determined based on scheduling information from the network/base station and control information from another device.

Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for handling of a RRC connection request message of a remote UE by a Relay UE in wireless communication system, the method comprising: receiving NAS information for establishing RRC connection of the remote UE from a remote UE which is configured to connect to the relay UE via sidelink in state that both of the remote UE and the relay UE are in RRC idle states, transmitting a RRC connection request message with an identity of the remote UE to an eNB, when a NAS layer of the relay UE triggers only service request for the remote UE; transmitting a RRC connection setup message for the remote UE to the remote UE; and transmitting a RRC connection setup complete message with the received NAS information of the remoter UE to the eNB.

Abstract: A user equipment (UE) (first UE) receives setting information about a plurality of transmission (Tx) resource pools and a plurality of reception (Rx) resource pools for a cell. On the basis of the setting information, and the identity (ID) of the first UE (first UE ID) or the ID of another UE (second UE) (second UE ID) connected for proximity-based wireless communication with the first UE, the first UE determines a portion (Tx resource group) of the plurality of Tx resource pools and a portion (Rx resource group) of the plurality of Rx resource pools. The first UE performs sidelink transmission to the second UE by using a Tx resource pool which belongs to the Tx resource group. The first UE performs sidelink reception from the second UE by using an Rx resource pool which belongs to the plurality of Rx resource groups.
