Abstract: A communication method and apparatus are provided to reduce interference between different types of satellites. The method is: A terminal device determines a satellite type corresponding to a first area, and the terminal device determines, based on the satellite type, whether to access a network device covering the first area. The terminal device determines, based on the determined satellite type corresponding to the first area, whether the network device can be accessed, so that a type of the network device accessed by the terminal device is consistent with the satellite type of the first area, and the terminal device can access only one type of satellite. When a plurality of types of satellites reuse a same frequency, the terminal device may receive signals of the plurality of types of satellites in the first area.

Abstract: The present disclosure relates to priority flow control (PFC) storm detection and processing methods. In one example method, a first network node performs PFC detection on a first port queue of a first port, and determines that a first preset condition is met. The first preset condition includes: detection is performed in N consecutive first time segments, when the detection is performed in each first time segment, a quantity of first PFC frames sent by the first port queue to a second network node is greater than a first threshold, and a quantity of one or more data packets received by the first port queue from the second network node is less than a second threshold. The first PFC frame is used to indicate the second network node to suspend sending all data flows in the first port queue, and N is a positive integer.

Abstract: A wireless communication includes determining, by a satellite, at least one first signal, sending the at least one first signal to a terminal based on at least one first beam, and receiving a random access request from the terminal. Each first signal of the at least one first signal corresponds to one first beam of the at least one first beam. Each first signal of the at least one first signal includes information about a first geographical location of a center point of the one first beam of the at least one first beam corresponding to each first signal of the at least one first signal. The information about the first geographical location is useable to determine a second beam from the at least one first beam. The random access request includes an identifier of the second beam.

Abstract: This application provides an information indication method and apparatus for a non-terrestrial communication network. The method includes: A terminal receives first indication information, where the first indication information includes a bandwidth part BWP indication field, and the BWP indication field indicates a BWP identifier offset; the terminal determines a second bandwidth part identifier BWP_ID based on the BWP identifier offset, where the second BWP_ID corresponds to a target beam of the terminal; and the terminal switches to the target beam. The method extends indication of BWP identifiers on a premise of compatibility with indication based on conventional downlink control information DCI.

Abstract: A gateway station switching method and apparatus. When quality of a link from a terminal device to a source gateway station through a satellite is poor, the source gateway station sends third indication information to a target gateway station, so that the target gateway station feeds back second channel quality to the source gateway station, that is, quality of a link from the terminal device to the target gateway station through the satellite. The source gateway station determines, based on the second channel quality and first channel quality that represents the quality of the link from the terminal device to the source gateway station through the satellite, whether to switch the terminal device to the target gateway station.

Abstract: The disclosure provides information transmission methods and communication apparatuses. One example method includes that a receiving apparatus receives a synchronization signal and cell-specific information that are sent by a sending apparatus on a first beam, where the cell-specific information includes indication information which indicates whether there is beam-specific information, and the first beam comprises a plurality of second beams. In response to determining that the indication information indicates that there is the beam-specific information, the receiving apparatus receives beam-specific information of second beam of the plurality of second beams, where the beam-specific information is sent by the sending apparatus on the second beam, and the receiving apparatus is within coverage of the second beam. The receiving apparatus performs initial access using the synchronization signal, the cell-specific information, and the beam-specific information.

Abstract: The present disclosure relates to communication methods and apparatuses. In one example method, a terminal device receives first information from an access device, and determines a first bandwidth part (BWP) of an access beam of the terminal device based on the received first information and a second BWP configured for the access beam of the terminal device. Then, the terminal device communicates with the access device in the determined first BWP by using the access beam. The first information indicates a relationship between the first BWP and the second BWP. The second BWP is a dedicated BWP configured for the access beam of the terminal device.
