Various embodiments of the present disclosure disclose a method for transmitting and receiving a signal in a wireless communication system and an apparatus supporting the same.

Provided are a method and apparatus for controlling sidelink communication. The method for performing, by a terminal, sidelink communication, may include the steps of: for a sidelink HARQ operation, receiving, from a base station, sidelink discontinuous HARQ configuration information used for monitoring a physical downlink control channel (PDCCH); transmitting sidelink data; and monitoring, in a PDCCH discontinuous monitoring section, the PDCCH configured on the basis of discontinuous reception (DRX) parameters included in the sidelink discontinuous HARQ configuration information.

A method and apparatus for clearing a part of a sidelink grant 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 to a second wireless device, and receives, from a third wireless device, sidelink control information (SCI) which schedules sidelink transmission from the third wireless device. When (i) priority of the sidelink transmission from the third wireless device is higher than priority of the sidelink transmission to the second wireless device, (ii) reference signal received power (RSRP) measurement for the received SCI is higher than a threshold, and (iii) a resource for the sidelink transmission from the third wireless device overlaps with the first resource, the first wireless device clears the first resource from the set of resources, and adds a third resource to the set of resources.

Proposed is a method by which a first device performs wireless communication. The method may comprise the steps of: receiving information related to a configured grant (CG) resource from a base station; and performing sidelink transmission to a second device on the basis of the information related to the CG resource. For example, the information related to the CG resource may include information related to a period of the CG resource, information related to a time domain of the CG resource, information related to a frequency domain of the CG resource, and information related to a time offset of the CG resource. For example, a first CG resource may be allocated after a time offset of the CG resource from a first time point. For example, a second CG resource may be allocated after the period of the CG resource from the first CG resource. For example, the period of the CG resource may be in units of logical slots.

The present disclosure relates to a method and apparatus for applying logical channel restriction in a wireless communication system. According to an embodiment of the present disclosure, an operation method of a terminal in a wireless communication system includes: receiving configuration information associated with restrictions for logical channels; and identifying, based on the configuration information, an uplink resource allocated with a configured scheduling-radio network temporary identifier (CS-RNTI), wherein when a value of a new data indicator (NDI) of the CS-RNTI is 0, the uplink resource is considered as a configured grant.

Disclosed are an information processing method and apparatus, a storage medium, a processor and an electronic device. Said method comprises: receiving configuration information from a network side device, the configuration information being used for configuring a sidelink configured grant transmission resource, and the sidelink configured grant transmission resource being a transmission resource in a resource pool; determining, on the basis of the configuration information, time-domain information corresponding to the sidelink configured grant transmission resource; and according to the time-domain information corresponding to the sidelink configured grant transmission resource, determining a first hybrid automatic repeat request process ID. The present disclosure solves the technical problem in the related art of lacking a method for determining the HARQ process ID for sidelink configured grant.

A method for receiving downlink transmission by a terminal comprises the steps of: performing uplink transmission, which is related to channel occupancy shared between a base station and the terminal, to the base station; and receiving, from the base station, downlink transmission performed after a gap from a time point at which the base station has received the uplink transmission, wherein the downlink transmission is performed on the basis of channel access performed by the base station, the channel access is performed on the basis of the gap, and information included in the downlink transmission and a resource through which the downlink transmission is performed are determined on the basis of whether the base station has configured, for the terminal, a threshold value of energy detection for the channel occupancy.

According to an embodiment of the present disclosure, provided is a method for performing wireless communication by a first apparatus. The method may comprise the steps of: receiving, from a base station, RRC configuration information about sidelink CG resources; transmitting a PSCCH to a second apparatus via a sidelink transmission resource determined on the basis of the RRC configuration information; and transmitting, to the second apparatus via the sidelink transmission resource, a PSSCH associated with the PSCCH.

Apparatus, methods, and computer-readable media for facilitating support for an increased quantity of sidelink configured grants are disclosed herein. An example method for wireless communication at a user equipment (UE) includes receiving scheduling information corresponding to a first quantity of sidelink configured grants, the first quantity of sidelink configured grants being greater than eight sidelink configured grants. The example method also includes receiving, from a base station, an activation of a sidelink configured grant of the first quantity of sidelink configured grants. The example method also includes transmitting sidelink traffic to a second UE based on the sidelink configured grant.

Techniques described herein include solutions for enabling NR sidelink (SL) communications by using radio resource control (RRC) to provide ser equipment (UEs) with grant configuration (CGs) for unidirectional and/or bidirectional SL communications. These techniques also include solutions for UEs to obtain channel occupation times (COTs) for SL communications, and procedures for sharing COTs with other UEs, and procedures for CG uplink control information (UCI) of physical uplink shared channels (PUSCH) transmissions for NR in the unlicensed spectrum (NR-U). The techniques described herein also include solutions for channel state information (CSI) feedback for CGs of SL in the unlicensed spectrum (CG-Sidelink-U). Also described herein are SL techniques for transmission power control of SL communications and clear channel assessment (CCA) procedures.
