The method may comprise the steps of: receiving, from a base station, first downlink control information (DCI) for activating a configured sidelink (SL) grant, wherein the first DCI includes information related to a physical uplink control channel (PUCCH) resource for reporting SL hybrid automatic repeat request (HARD) feedback to the base station; transmitting a medium access control protocol data unit (MAC PDU) to a second device through a physical sidelink shared channel (PSSCH) on the basis of the configured SL grant; receiving, from the base station, second DCI for deactivating the configured SL grant; transmitting, to the base station, an SL confirmation medium access control (MAC) control element (CE) in response to the second DCI; and determining whether the PUCCH resource related to at least one SL resource allocated by the configured SL grant is valid on the basis of the time at which the SL confirmation MAC CE was transmitted.

The present application relates to a method for determining transmission resources and a terminal device. The method includes: determining, by a terminal device, a time domain position of a time unit; and determining, by the terminal device, a time domain position of a sidelink configured grant transmission resource according to the determined time domain position of the time unit and a first resource pool. The first resource pool is a resource pool associated with the sidelink configured grant.

According to at least one of the embodiments disclosed herein, a user equipment (UE) may transmit a configured grant (CG) based physical uplink shared channel (PUSCH). However, based on that the CG-based PUSCH is transmitted in a radio resource control (RRC) Inactive state and that the CG-based PUSCH is associated with a specific synchronization signal block (SSB) among broadcast SSBs, the UE may monitor a physical downlink control channel (PDCCH) based on the specific SSB while maintaining the RRC Inactive state.

The method includes: A terminal device obtains one or more measurement results respectively corresponding to one or more reference signals, and determines a CEL of the terminal device based on the one or more measurement results and at least one of N thresholds, where the N thresholds are a threshold 0, a threshold 1, . . . , and a threshold (N−1) in descending order. If there is a measurement result greater than or equal to the threshold 0 in the one or more measurement results, the CEL of the terminal device is a CEL 0. If the one or more measurement results are less than a threshold i, and there is a measurement result greater than or equal to a threshold (i+1), the CEL of the terminal device is a CEL (i+1), and a value of i is an integer from 0 to (N−2).
