Abstract: This application provides a cell access method, a communication apparatus, and a computer storage medium. The method includes: A network device sends one or more reference signals to a terminal. The terminal sends corresponding first indication information to the network device based on a first reference signal in the received one or more reference signals, where the first indication information indicates the network device to send a downlink common signal, so that the terminal may access a target cell based on the downlink common signal.

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.

Abstract: A response information transmission method and an apparatus are provided. After receiving first downlink data from a network device, a terminal device transmits the first downlink data in a semi-persistent scheduling manner, and determines, based on a transmission status of first response information of the first downlink data, whether to send the first response information to the network device. The transmission status may include two states: One state represents that the first response information and first uplink information are to be simultaneously transmitted in a first time unit, and the other state represents that the first response information is to be separately transmitted in the first time unit. When the first response information is to be separately transmitted in the first time unit, the network device determines, based on the transmission status of the first response information, whether to receive the first response information.

Abstract: This application provides a method for multiplexing uplink control information, and relates to the wireless communications field. When a resource of a first uplink control channel that carries first HARQ-ACK information does not overlap a resource of a second uplink control channel that carries second HARQ-ACK information in time domain, but a resource of a third uplink control channel that carries an SR/CSI overlaps both the resource of the first uplink control channel and the resource of the second uplink control channel in time domain, a base station and UE determine, based on a format of the first uplink control channel, a format of the second uplink control channel, and a format of the third uplink control channel, that third HARQ-ACK information and first UCI are multiplexed for transmission, where the third HARQ-ACK information is the first HARQ-ACK information or the second HARQ-ACK information.
