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.

Abstract: Embodiments of the present disclosure provide a data transmission method. The method includes: sending, by a network device, first indication information, where the first indication information includes N bits, the N bits are corresponding to M time units, the M time units are corresponding to at least one time length, a value of each bit is used to indicate whether a corresponding time unit is used to transmit data of a terminal device, M is an integer greater than or equal to 1, and N is an integer greater than or equal to 1; and sending, by the network device, downlink data in a time unit that is used to transmit the data of the terminal device, where the time unit is indicated by the N bits. Therefore, a unified time domain resource indication manner can be used in different scenarios to reduce complexity of a signaling design.

Abstract: In a data receiving method, a terminal receives first indication information, where the first indication information indicates a target frequency domain position. The terminal determines a first time-frequency resource based on a time domain position of a control resource set and the target frequency domain position, where a frequency domain position of the first time-frequency resource is the same as the target frequency domain position. The terminal receives data on a target time-frequency resource, where the target time-frequency resource includes a second time-frequency resource and a part of resources in the first time-frequency resource; or the target time-frequency resource includes a second time-frequency resource but does not include the first time-frequency resource, where N is a positive integer.
