Uplink control information sending and receiving method and communications apparatus
This application provides a UCI sending and receiving method and a communications apparatus. In the method, an association relationship between a PUCCH and a PUSCH is established, so that when resources of the PUSCH and the PUCCH overlap, a terminal device can determine UCI on which PUCCHs can be transmitted by multiplexing the resource of the PUSCH. A network device may receive the UCI on the PUSCH. Because the network device may know in advance which PUCCHs and PUSCHs are sent to the network device, the network device can demodulate and decode a signal on the received PUSCHs, to successfully obtain UCI. The network device can make a proper decision based on the UCI.
