Abstract: The present invention relates to the field of communications network technologies, and discloses a data processing method and apparatus. In embodiments of the present invention, stream channel quality information is obtained, and then port mapping of a to-be-transmitted data stream is determined according to the stream channel quality information. The port mapping is used to make channel quality of data streams distributed in a same code word satisfy the following: a sum of fluctuation values that is used to represent channel quality of data streams in all code words is less than a sum of fluctuation values that is used to represent channel quality of data streams in all code words under original port mapping.

Abstract: Example communication methods and apparatus are described. One example method includes generating a first signal and sending a first signal, where the first signal includes an orthogonal frequency division multiplexing (OFDM) symbol, a first-type cyclic prefix (CP), and a second-type CP. CP resources of the first-type CP include two types of CP resources: a first CP resource and a second CP resource. CP resources of the second-type CP include one type of CP resource, that is, the second CP resource. The first CP resource may be used to carry data that is different from data carried on the OFDM symbol. The second CP resource may be used to carry data that is the same as the data carried on the OFDM symbol.

Abstract: This disclosure provides a beam information indication method and an apparatus. The terminal device obtains reference domain information of a plurality of beams and a first offset corresponding to each moment, to update beam domain information, where the first offset indicates an offset of domain information of the plurality of beams relative to the reference domain information of the plurality of beams. In technical solutions provided in this disclosure, domain information of the plurality of beams can be updated with low signaling overheads. The technical solutions may be applied to a satellite communication system, to implement interference management of satellite beams.

Abstract: Example communication methods and apparatus are described. In one example method, a terminal receives a first information by using a serving beam, where the first information indicates a delay compensation parameter corresponding to a target beam. The target beam and the serving beam are different beams. The terminal determines, based on a full timing advance and the delay compensation parameter corresponding to the target beam, a differential timing advance corresponding to the target beam.

Abstract: The disclosure provides transmission methods and apparatuses. One example includes sending control signaling to a terminal device, to indicate the terminal device to send a physical uplink shared channel (PUSCH) on a first frequency band; and receiving the PUSCH sent by the terminal device on the first frequency band. The first frequency band includes at least one guard subcarrier. A quantity of the at least one guard subcarrier is determined based on a Doppler frequency shift of a beam covering the terminal device. The first frequency band is located on a frequency band corresponding to the beam.
