Abstract: This application relates to the field of communication technologies, and discloses a communication method and apparatus. The method includes: A terminal device receives an identifier of a filtering protocol version from an access network device, and then sends first capability information of the terminal device to the access network device based on the filtering protocol version. In this method, the terminal device may report capability information based on the filtering protocol version sent by the access network device. Compared with a manner in which the terminal device directly reports the capability information, this method can effectively reduce a communication problem caused by mismatch between a protocol version supported by the terminal device and a protocol version supported by the access network device and/or a protocol version supported by a core network device.

Abstract: Example information transmission methods, and apparatus are described. One example information transmission method includes determining resources for carrying N pieces of uplink control information (UCI) that partly overlap or completely overlap in time domain. The N pieces of UCI comprise at least one piece of beam channel quality information and at least one of a piece of channel state information or an acknowledgement (ACK)/a negative acknowledgement (NACK). A priority of the beam channel quality information is higher than a priority of the channel state information. A priority of the beam channel quality information is lower than a priority of the ACK/NACK.

Abstract: Example hybrid automatic repeat request (HARQ) feedback methods and apparatus are provided. One example method includes a network device obtains first indication information used to instruct a terminal device to feed back HARQ feedback information. The first indication information is obtained based on information amounts corresponding to a data channel and/or information amounts corresponding to a control channel that are in a reference slot and at least one first slot. The reference slot and the at least one first slot each correspond to a different component carrier of a plurality of component carriers serving the terminal. The reference slot and the at least one first slot have a same start moment, and at least two of the plurality of component carriers have different slot lengths. The network device sends, to the terminal device, indication information used to indicate at least the first indication information.
