Abstract: The present disclosure relates to communication methods and apparatuses. In one example method, a first access network device determines configuration information, and sends the configuration information to a terminal. The first access network device is connected to a first core network device, and the first core network device uses a first or second communication standard. The configuration information includes status indication information of a first protocol layer (for example, a service data adaptation protocol (SDAP) layer) of the second communication standard, and the status indication information indicates the terminal to perform or not to perform a function of the first protocol layer. The first access network device determines a state of the first protocol layer based on a protocol layer specified in a communication standard of the core network device.

Abstract: In a communication method disclosed in this application, a terminal device receives, from a network device, a synchronization signal and a system information signal that are generated based on a first subcarrier spacing. The terminal device sends a random access request signal to the network device based on a second subcarrier spacing and a first transmission resource, where a type of the first transmission resource corresponds to a third subcarrier spacing and/or a fourth subcarrier spacing. The terminal device further receives a random access response signal generated based on the fourth subcarrier spacing, where the random access response signal is used for instructing the terminal device to access a network or the random access response signal is used for instructing the terminal device to prepare to access network. Thereby, cell search for and random access to a network using a plurality of subcarrier spacings can be supported.

Abstract: A terminal receives downlink scheduling information of a downlink subframe F(i, j), where a set M of preconfigured downlink subframes in which the downlink subframe F(i, j) is located is divided into N subsets of preconfigured downlink subframes, a bit quantity of a hybrid automatic repeat request-acknowledgement HARQ-ACK that needs to be fed back for each downlink subframe in one subset of preconfigured downlink subframes is a predetermined value, and bit quantities of HARQ-ACKs that need to be fed back for any downlink subframes in different subsets of preconfigured downlink subframes are different. The terminal generates a HARQ-ACK codebook according to a receiving status of downlink data. And the terminal generates uplink control information after encoding the HARQ-ACK codebook; and a sending module sends the uplink control information.
