Abstract: An apparatus and method, the method including receiving, by a terminal device, first configuration information from a network device, where the first configuration information indicates a second reporting mode, and the second reporting mode indicates to feed back hybrid automatic repeat request (HARQ-ACK) information based on a negative acknowledgment only (NACK-only), and when determining that a resource set overlaps a unicast uplink resource, sending, by the terminal device, the HARQ-ACK information for a multicast service to the network device in a first reporting mode, where the first reporting mode indicates to feed back the HARQ-ACK information based on an acknowledgment (ACK) or a NACK, the resource set comprises a plurality of multicast physical uplink control channel (PUCCH) resources, and the unicast uplink resource comprises a unicast PUCCH resource or a unicast physical uplink shared channel (PUSCH) resource, and the HARQ-ACK information comprises an ACK value or a NACK value.

Abstract: A wireless communication method and apparatus for improving communication failure recovery efficiency. The method is applied to a terminal or a chip used in a terminal, and includes: upon detecting that downlink communication of the first serving cell fails, determining that downlink communication of the second serving cell is normal; sending a communication failure recovery request on an uplink channel of the second serving cell, where the communication failure recovery request is used to request to recover from a downlink communication failure of the first serving cell; and detecting a communication failure recovery response on a downlink channel of the second serving cell, where the communication failure recovery response is used to indicate a downlink communication resource of the first serving cell.

Abstract: This application provides a method and an apparatus for determining transmit power. The method includes: A terminal device determines a first bit rate of channel state information part 1 CSI-1, where the first bit rate is a bit quantity of the CSI-1 carried on each resource element for transmitting the CSI-1; and the terminal device adjusts transmit power of a physical uplink shared channel PUSCH based on the first bit rate, where the PUSCH is used to carry the CSI-1.
