Abstract: A beam failure recovery BFR method and an apparatus are provided. The method includes: A terminal receives indication information of a first threshold and a second threshold, where the second threshold is used to determine that a beam failure occurs on an access network device. The terminal collects statistics on quantities of beam failure instance times of one or more access network devices that communicate with the terminal based on beams in a cell; and performs beam recovery on an access network device whose quantity of beam failure instance times is greater than or equal to the first threshold and less than the second threshold. The method and the apparatus in this application can further reduce a possibility of the beam failure, improve network reliability, and avoid beam failures on a plurality of devices in the cell at the same time.

Abstract: A communication method includes determining, by a terminal side device, that a consistent uplink listen before talk (LBT) failure occurs in a first bandwidth part (BWP) of a cell. The communication method also includes canceling, by the terminal side device, a consistent uplink LBT failure status of the cell in response to a determination by the terminal side device to switch to a second BWP of the cell.

Abstract: This application provides a random access method and apparatus. The method includes: A terminal device receives first information sent by a network device, where the first information includes a priority value of a first parameter used for a random access procedure. The terminal device initiates the random access procedure based on the priority value. In this way, the terminal device can preferentially select, based on the priority value of the first parameter, a two-step random access procedure or send a message in the random access procedure by using high power, to quickly access a network and reduce an access delay.

Abstract: A communication method and an apparatus are provided, to resolve a problem of low data transmission efficiency. The method includes: in response to receiving a paging message from a terminal device, a terminal device determines, based on a preconfiguration and/or the paging message, a first physical uplink shared channel (PUSCH) resource used to transmit a paging response, and sends the paging response to the access network device on the first PUSCH resource, where the paging response carries identity authentication information of the terminal device. After the access network device or a core network successfully performs identity authentication on the terminal device, downlink data transmission can be performed. Compared with a manner in which downlink data transmission can be performed only after a radio resource control (RRC) connection is set up or resumed, this manner can improve data transmission efficiency.
