Abstract: A method and apparatus for sidelink connection suspension or release based on different target qualities of different services in a wireless communication system is provided. A first wireless device determines a first target cell quality for a first service related to a first bearer and a second target cell quality for a second service related to a second bearer. The first wireless device suspends at least one of the first bearer and/or the second bearer based on that a result of the measurement on a sidelink connection does not meet at least one of the first target cell quality and/or the second target cell quality. The first wireless device releases the sidelink connection if there is no more service using the sidelink connection.

Abstract: The present invention relates to a wireless access system that supports an unlicensed band, and provides various methods for adjusting a contention window size, methods for determining the time when the adjusted contention window size is applied, methods for distinguishing between a collision and a channel error, and devices for supporting the same. As an embodiment of the present invention, a method for adjusting a contention window size in a wireless access system supporting an unlicensed band may comprise the steps of: performing a channel access procedure; when it is determined through the performed channel access procedure that a serving cell (Scell) in the unlicensed band is in an idle state, transmitting a transmission burst including a downlink signal through the unlicensed band; receiving hybrid automatic repeat and request acknowledgment (HARQ-ACK) information corresponding to the transmission burst; and adjusting the CWS using the number of DTX states in the HARQ-ACK information when the transmission burst is scheduled in a self-carrier scheduling scheme.

Abstract: A method and apparatus for activation and retransmissions for a pool of resources is provided. A first device autonomously selects a set of resources on a pool of resources for N number of transmissions of a Transport Block (TB) stored in a process. The first device transmits, to the network, a request for a retransmission grant for the process based on i) the N number of transmission being completed and ii) retransmission of the TB being required. The request includes a Hybrid Automatic Repeat request (HARQ) process identifier (ID) associated to the process.

Abstract: Provided herein is a method for performing, by a first apparatus, wireless communication and an apparatus for supporting the same. The method may include the steps of generating a Phase Tracking-Reference Signal (PT-RS), transmitting a Physical Sidelink Control Channel (PSCCH) to a second apparatus, mapping, based on a Cyclic Redundancy Check (CRC) on the PSCCH, the PT-RS to a subcarrier on a Physical Sidelink Shared Channel (PSSCH) resource related to the PSCCH, and transmitting the PT-RS to the second apparatus.

Abstract: The present invention relates to a resource allocation method of a vehicle-to-everything (V2X) transmission terminal in a wireless communication system and an apparatus therefor. More specifically, the method comprises the steps of: transmitting, to a V2X receiving terminal, a first V2X signal for a V2X service; receiving, from the V2X receiving terminal, an acknowledgment/negative-acknowledgment (ACK/NACK) for a V2X signal; and, if the NACK is received from the V2X receiving terminal, allocating, for a second V2X signal, a second time-frequency resource reserved in association with a first time-frequency resource for the first V2X signal.

Abstract: Proposed is a method of performing wireless communication by a first apparatus. The method may include receiving first control information on a first search space related to the first control information, and receiving second control information on a second search space related to the second control information. For example, the first search space related to the first control information may overlap with the second search space related to the second control information, based on that a base station allocates a resource related to sidelink transmission to the first apparatus in a carrier in which Uu communication is performed.
