A communication method includes that a first device deletes a first data packet. The first device sends first signaling to a second device, where the first signaling includes or indicates a first buffer, the first buffer is used to compress a second data packet or used to decompress a compressed second data packet, a serial number of the first data packet and a serial number of the second data packet are consecutive, the serial number of the second data packet follows the serial number of the first data packet, and the second device is a receiving device of the compressed second data packet.

Method and device to decompress data packets

A communication method includes a first device configuring a plurality of buffers to compress data packets. Each of the plurality of buffers is used to compress one or more data packets for transmission. If a compressed data packet is lost during transmission, a receive end cannot decompress a data packet corresponding to a same buffer as the lost data packet, but the receive end can continue to decompress a data packet that does not correspond to the same buffer as the lost data packet.

Communication method and apparatus

A method includes: determining, by a terminal device, that assistance information of the terminal device can be sent to a first network device through a signaling radio bearer (SRB) 3, wherein the terminal device is connected to at least two network devices, and the first network device is a secondary network device in the at least two network devices; and sending, by the terminal device, the assistance information to the first network device through the SRB3, wherein the assistance information is used to indicate a configuration expected by the terminal device or service information of the terminal device.

Communications method and device

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.

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.

Pending SR cancellation method and apparatus
