Abstract: Example communication methods and apparatus are described. One example method includes performing first listen before talk (LBT) and sending a first data packet on a first uplink burst after the first LBT succeeds. A second contention window size is determined based on the first contention window size and a first reference time unit. Second LBT is performed based on the second contention window size. The first contention window size is used for a LBT previous to the second LBT, the first reference time unit is later than the second reference time unit corresponding to the first uplink burst. The first reference time unit is a time unit for determining the second contention window size, or a starting time unit of a second uplink burst corresponding to the second LBT. The second reference time unit corresponding to the first uplink burst is a time unit in the first uplink burst.

Abstract: Embodiments of this application provide a communication method and an apparatus, relate to the communication field, and in particular, are applicable to a broadcast system. The method includes: A terminal device receives a first downlink channel from an access network device, where the first downlink channel is scrambled by using a first identifier and is used to carry first data. The terminal device receives a second downlink channel from the access network device, where the second downlink channel is scrambled by using a second identifier and is used to retransmit the first data. The first identifier and the second identifier are identifiers configured by the access network device. This method can implement a feedback retransmission mechanism combining broadcast initial transmission and partial retransmission, to further improve spectral efficiency of a communication system.
