Abstract: This application provides a data transmission method and an apparatus, to resolve a problem of high multicast transmission control signaling overheads. The method includes: receiving first multicast data using a multicast based semi-persistent scheduling SPS transmission; receiving first downlink control information DCI, where the first DCI is scrambled by a configured scheduling radio network temporary identifier CS-RNTI; and receiving first data based on the first DCI, where the first data is retransmitted data of the first multicast data.

Abstract: This application provides an interference reporting method. A terminal device performs interference measurement on a first time-frequency resource, to obtain an autocorrelation matrix of an interference signal, further determines a first interference parameter based on the autocorrelation matrix of the interference signal, and reports the first interference parameter to a network device. Therefore, the network device can restore the autocorrelation matrix of the interference signal on the terminal device side. This helps the network device perform more accurate downlink data scheduling.

Abstract: Embodiments of this application provide a communication method, apparatus, and system. In an example method, in response to determining that a first condition is met, a terminal device determines a target physical uplink control channel (PUCCH) resource, and sends an acknowledgment codebook to a network device on the target PUCCH resource. The first condition includes: a first PUCCH resource overlaps a second PUCCH resource, or a first PUCCH resource and a second PUCCH resource are in a same time unit. The first PUCCH resource carries first feedback information corresponding to first downlink data. The first feedback information includes first negative acknowledgement (NACK) information of the first downlink data but does not include first positive acknowledgement (ACK) information.

Abstract: This application provides an uplink control information transmission method and an apparatus. In the method, a terminal device obtains first physical uplink control channel PUCCH configuration information corresponding to multicast data and second PUCCH configuration information corresponding to unicast data. When first hybrid automatic repeat request-acknowledgment HARQ-ACK information corresponding to received multicast data and second HARQ-ACK information corresponding to received unicast data have a same priority and are to be fed back in a same time unit, the terminal device may determine a PUCCH resource based on the first PUCCH configuration information or the second PUCCH configuration information, and then send uplink control information on the PUCCH resource. The uplink control information includes the first HARQ-ACK information and the second HARQ-ACK information.

Abstract: In an interference control method, a first network device sends first indication information to a first terminal device, where the first indication information indicates a first reference signal (RS). The first terminal device obtains, based on measurement on the first RS, first interference information corresponding to the first RS, determines a first transmission parameter based on the first interference information, and sends uplink information to the first network device on a first time-frequency resource based on the first transmission parameter.
