Abstract: A random access preamble sending method and an apparatus is provided. The method includes sending, by user equipment, a first random access preamble to a network device, where the first random access preamble is used by the user equipment to access the network device; and when the user equipment fails in accessing the network device by using the first random access preamble, sending at least one second random access preamble to the network device, where access characteristic information of each second random access preamble is different from that of the first random access preamble, the access characteristic information includes at least one of a time length, a transmit beam, and a random access resource, and the at least one second random access preamble is used by the user equipment to access the network device.

Abstract: This application provides a method for transmitting a paging message, a terminal device, and a network device. The method includes: determining, by a terminal device, a target paging resource, where the target paging resource includes at least one of the following types of information: position information of a target paging occasion, position information of a target paging frame, and position information of a target monitoring window; and receiving, by the terminal device, a target paging message on the target paging resource, where the target paging message is a paging message sent by a network device to the terminal device. The terminal device and the network device can be used in a communications system applying a beamforming technology, so that the terminal device can receive a paging message sent by the network device to the terminal device.

Abstract: A communication method and a related apparatus. The communication method includes determining, based on a starting location of a first remaining minimum system information RMSI detection window and a time index of a synchronization signal (SS)/physical broadcast channel (PBCH) block, a starting location of an RMSI detection window corresponding to a terminal device, where a value of the starting location of the RMSI detection window is one of four possible values of the starting location of the RMSI detection window, and receiving the RMSI based on the starting location of the RMSI detection window.

Abstract: This application provides a random access method, a terminal, and a network device. The random access method includes: determining, by a terminal, whether a resource used for random access conflicts with a resource used for receiving a downlink signal; and if the resource used for the random access conflicts with the resource used for the downlink signal, preferentially using the conflicting random access resource for receiving the downlink signal but not for the random access.
