Abstract: A communications method and apparatus are provided. A network device determines whether a first capability of a terminal device is less than or equal to a second capability of the terminal device. The first capability is a capability of the terminal device of working at a first frequency when the terminal device supports only a first radio access technology, and the second capability is a capability of the terminal device corresponding to the first frequency in a first frequency combination. When the first capability is less than or equal to the second capability, the network device sends a first message to the terminal device. The first message is used to indicate the terminal device to measure a second frequency, the first message does not include a configuration of a first measurement gap, and the first measurement gap is used to measure the second frequency.

Abstract: This application provides a data transmission method and an apparatus, and relates to the field of communication technologies. According to the method, a first network device sends a first message including first information to a remote terminal device. The first message indicates the remote terminal device to switch from being connected to the first network device through a first path to being connected to a second network device through a second path. The first path includes at least one relay terminal device. The second path includes at least one relay terminal device or does not include a relay terminal device. The first information indicates a receiving status of a first PDCP entity of the first network device. The first information is carried in a switch command, so that the remote terminal device can receive the first information as soon as possible.

Abstract: This application provides a communication method and a communications device. The method includes: A first device receives a first message sent by a second device. The first message is used to indicate a bearer configuration of a bearer of the first device and an initial status of the bearer configuration, and the bearer configuration includes a first bearer configuration and/or a second bearer configuration. The first device determines the bearer configuration and the initial status of the bearer configuration based on the first message. According to the technical solutions in embodiments of this application, a bearer configuration of a terminal device and an initial status of the bearer configuration of the terminal can be indicated. Because both the bearer configuration of a bearer of the terminal and the initial status of the bearer configuration of the terminal are indicated, communication efficiency is improved.

Abstract: This application provides a pending SR cancellation method and an apparatus. In the method, when a specific condition is met, a terminal cancels a pending SR triggered by an uplink BSR, and when some other conditions are met, the terminal cancels a pending SR triggered by a sidelink BSR. In other words, the terminal may independently cancel the SR triggered by the uplink BSR and the SR triggered by the sidelink BSR. When canceling the SR triggered by the uplink BSR, the terminal may not cancel the SR triggered by the sidelink BSR, so that when sidelink data has a relatively high latency requirement.
