Abstract: Embodiments of this application provide a multicast transmission control method. A terminal side device gives a feedback to an access network side device for a received multicast service, the feedback indicating that the terminal side device successfully receives the multicast service or fails to receive the multicast service, so that the access network side device can learn a status of the sent multicast service. This facilitates optimization of transmission of the multicast service.

Abstract: A bandwidth part processing method and apparatus is provided. The method includes: when an inactivity timer corresponding to an active first bandwidth part BWP expires, determining whether a carrier in which the first BWP is located includes a second BWP in an active state; and when the carrier includes the second BWP in the active state, deactivating the first BWP. According to this method, an unnecessary BWP switch procedure can be avoided.

Abstract: A communications method and apparatus. The communications method includes: transmitting a first request to a network device through a first resource, where the first request is used to request beam failure recovery of a first cell or is used to request system information of the first cell, the first resource is a resource of a second cell, and the first cell and the second cell are serving cells of a same terminal; and receiving a first response corresponding to the first request from the network device. Therefore, when a terminal has a plurality of serving cells, the terminal may transmit a request across cells (or across carriers), to improve transmission reliability.

Abstract: A communication method is provided. In the method, if a first logical channel of a terminal device does not have an uplink resource for carrying a scheduling request (SR) and the terminal device is in a first SR state, remaining, by the terminal device, in the first SR state and/or a first buffer status report (BSR) state until data of the first logical channel and/or a BSR are/is sent, where the BSR is used to indicate buffer status information of a logical channel group including the first logical channel. When a logical channel of the terminal device does not have an uplink resource for carrying the scheduling request, a problem that the terminal device cannot obtain an uplink transmission resource can be resolved.

Abstract: A communication method and apparatus resolves a problem that a resource usage status reported by a network device is inaccurate. The method includes: a first network device receives resource status information from a second network device, where the resource status information includes LBT-related resource information; and the first network device determines a resource usage status of the second network device based on the resource status information. In the foregoing manner, the first network device may determine a resource that is to be released by the second network device, a resource that may be occupied, and the like. In this way, the first network device may perform conversion on the resource usage status of the second network device, to obtain an accurate resource usage status, and in particular, have more accurate estimation on an estimated future resource usage status.

Abstract: A communication method and apparatus. A terminal device determines a priority of a first hybrid automatic repeat request HARQ process. The terminal device determines a target HARQ process from the first HARQ process based on the priority, to transmit data to a network device on a target configured grant by using the target HARQ process. The first HARQ process includes at least one HARQ process corresponding to the target configured grant thereby reducing a latency of transmitting data by using the target HARQ process.

Abstract: This application provides a communication method and apparatus. In an example method, when a first access network device performs unsuccessful listen before talk (LBT) for channel detection on an unlicensed channel, the first access network device sends first indication information to a second access network device. The first indication information indicates that the first access network device performs unsuccessful LBT for channel detection on the unlicensed channel.
