Abstract: A method for performing wireless communication by a first device and an apparatus for supporting same are provided. The method may comprise: receiving, from a base station, information related to a first sidelink (SL) resource and information related to a first physical uplink control channel (PUCCH) resource; transmitting, to a second device, a medium access control (MAC) packet data unit (PDU) by using the first SL resource, wherein the MAC PDU includes a packet related to a logical channel for which hybrid automatic repeat request (HARQ) feedback is disabled, and wherein the MAC PDU includes no packet related to a logical channel for which HARQ feedback is enabled; determining that retransmission of the MAC PDU is required; and transmitting, to the base station, NACK information by using the first PUCCH resource based on no SL grant available for retransmission of the MAC PDU.

Abstract: The present disclosure provides a method of receiving a physical downlink shared channel (PDSCH) by a user equipment (UE) in a wireless communication system. The method may include: receiving a parameter related to discontinuous reception (DRX) operation through a higher layer; receiving first downlink control information (DCI) including information related to physical downlink control channel (PDCCH) monitoring adaptation; receiving second DCI for scheduling the PDSCH within a DRX active time of the DRX operation, based on the information related to the PDCCH monitoring adaptation; and receiving the PDSCH based on the second DCI. The PDCCH monitoring adaptation may be determined based on jitter related to the PDSCH.

Abstract: A user equipment (UE) receives a SPS resource configuration from an eNodeB (eNB), and transmits information related to a semi-persistent scheduling (SPS) activation for a specific logical channel to the eNB. The information may include timing information for the specific logical channel which indicates when a SPS resource for the specific logical channel should be activated. The specific logical channel may correspond to a vehicle-to-everything (V2X) communication.

Abstract: Performing a random-access channel procedure (RACH procedure) by a terminal in an unlicensed band. Specifically, a method may include: transmitting message A including a first physical random-access channel (PRACH) and a first physical uplink shared channel (PUSCH) to a base station; and receiving contention resolution-related message B from the base station in response to message A, wherein a power ramping counter is used to configure transmission power of message A, and the power ramping counter has a value which increases based on that a transmission spatial beam for transmission of message A is configured to be identical to a transmission spatial beam related to transmission of a PRACH preceding message A.

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 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.
