摘要： Disclosed in the present application are a resource reselection method and apparatus, a device, and a storage medium, which relate to the technical field of communications. The method comprises: a terminal device determining a target selection slot and a target listen slot; according to a non-listen slot and/or a listen result within the target listen slot, excluding available resources within the target selection slot, so as to obtain a candidate resource set; and if it is determined that a first resource that has been selected by the terminal device is re-selected, selecting, from the candidate resource set, a second resource used for replacing the first resource. When the terminal device executes partial listen and performs semi-persistent transmission or periodic transmission, if it is determined, by executing a Pre-emption mechanism, that a resource is pre-empted, or it is determined, by executing a Re-evaluation mechanism, that a resource conflict occurs, communication reliability is improved by means of triggering resource reselection to avoid a resource collision.

摘要： Provided are a communication method and a communication apparatus. The method comprises: a terminal device determines that a first physical downlink control channel (PDCCH) is a group-common physical downlink control channel (GC-PDCCH); the terminal device determines that data carried in a first PDSCH scheduled by a first PDCCH is initial transmission of new data of multicast. In the method in embodiments of the present application, it may be determined that the current data (i.e., the data transmitted by the first PDSCH) is initial transmission of new data of an MBS service, without using a new data indicator (NDI) carried in the first PDCCH, thereby improving the communication efficiency.
