A communication method and apparatus are provided, and relate to the field of wireless communication technologies, to resolve a problem in a conventional technology that communication quality during communication between a satellite and a communication apparatus cannot be ensured, and to ensure security of high-accuracy location information of the satellite. In the method, the communication apparatus may perform random access to the satellite based on first location information. The communication apparatus may perform uplink communication with the satellite based on obtained second location information. Accuracy of a location obtained based on the second location information is higher than accuracy of a location obtained based on the first location information. Based on this solution, required accuracy of location information of the satellite is different.

One example method includes: generating a neighboring cell status function identifier by a satellite, where the neighboring cell status function identifier can be used to indicate an inactive state of at least one neighboring cell of a satellite cell. The satellite sends neighboring cell relationship configuration information that includes the neighboring cell status function identifier to a communications device, and the communications device determines a configuration status of a corresponding neighboring cell based on the neighboring cell relationship configuration information.

Embodiments of this application provide a data transmission method and related device. The method includes: A receive end receives data from a transmit end; and sends a first response message to the transmit end at a triggering moment of a first preset condition. The first response message comprises acknowledgement (ACK) or negative acknowledgement (NACK) determined based on a channel quality evaluation result obtained by the receive end after evaluating channel quality of a first channel of the transmit end. The first response message is used by the transmit end to determine, based on the ACK or NACK carried in the first response message, whether to resend the data. The receive end may estimate the channel quality in advance, to predetermine a data receiving status before the data is actually received, and return the channel quality to the transmit end at preset moments. This effectively shortens a data transmission delay.
