Abstract: This application provides a feedback information transmission method and a related apparatus. When the first PUCCH resource overlaps the downlink symbol or the flexible symbol in time domain, the terminal device may switch the HARQ feedback information to another time unit for sending. This resolves low data transmission reliability because the HARQ feedback information cannot be sent and is discarded when the first PUCCH resource overlaps the downlink symbol or the flexible symbol.

Abstract: This application discloses a communication method, apparatus, and system. A network device sends a first downlink common signal (for example, an SSB) to a terminal device. The terminal device receives system information from the network device based on the SSB. The system information carries information indicating a first frequency domain resource and a second frequency domain resource. The first frequency domain resource and the second frequency domain resource may be two carriers or two BWPs, and the two frequency domain resources correspond to different uplink-downlink configurations. The terminal device selects a first random access resource from a random access resource set based on an association relationship between an SSB and a random access resource to send a random access preamble. The random access resource set includes a random access resource on the first frequency domain resource and a random access resource on the second frequency domain resource.

Abstract: This application discloses a power control method for an uplink control channel, and an apparatus. Based on a time-frequency resource of a first physical uplink control channel (PUCCH) for carrying first uplink control information (UCI) and a time-frequency resource of a second PUCCH for carrying second UCI overlapping, a terminal sends the first UCI and the second UCI over a third PUCCH by using first power. The first power is determined based on a quantity of bits of the first UCI and/or a quantity of bits of the second UCI, to improve UCI transmission reliability in this scenario.
