Abstract: This application discloses a paging indication transmission method, including: sending, by a network device, a first paging indication to a terminal device; and sending, by the network device, a second paging indication to the terminal device, where the first paging indication and the second paging indication form a complete paging indication of the terminal device. According to the foregoing paging indication transmission method and apparatus, the network device delivers the paging indication at two times, to reduce a payload for a single transmission of the paging indication.

Abstract: An information sending and receiving method and an apparatus are disclosed. In an embodiment an information sending apparatus includes a processor configured to determine, based on a physical broadcast channel (PBCH) period or a synchronization signal block burst set (SS block burst set) period, a period in which remaining minimum system information (RMSI) is to be sent and a sender configured to send the RMSI to a terminal device by using X as the period, wherein X is a multiple of the PBCH period, or X and the PBCH period are in a one-to-one correspondence or a one-to-many relationship, and wherein a network device is configured to send at least one piece of RMSI by using at least one beam or antenna port.

Abstract: This application discloses a communications method and apparatus. The method includes: obtaining, by a terminal device, downlink synchronization signal block index information; receiving, by the terminal device, information used to indicate an association relationship between a random access resource RO and a synchronization signal block; and accessing, by the terminal device, a network device based on the information on an RO corresponding to the synchronization signal block index information. This application further discloses a corresponding apparatus. A time-frequency location of a random access resource associated with each downlink synchronization signal is indicated, so that the terminal device obtains, through downlink synchronization, a time-frequency location for sending an uplink random access signal, to avoid a blind attempt of the terminal device and a beam mismatch of the network device occurring when the network device receives a random access signal, thereby improving efficiency.

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. This avoids a conflict between receiving of the downlink signal and sending of an uplink random access preamble.

Abstract: This application provides a random access preamble transmission method and an apparatus. In one example method, a terminal receives indication information, and may indicate, with reference to the indication information, whether a first path loss is the same as a second path loss, and determine the first path loss based on the second path loss. Then, the terminal may set, based on a path loss for transmitting a random access preamble between the terminal and a network device, a transmit power for sending the random access preamble.

Abstract: A method includes a transmitting end sending a first signal that includes a data signal and a reference signal. A first imaginary reference signal in the reference signal is located at a real signal location of the first signal, and/or a first real reference signal in the reference signal is located at an imaginary signal location of the first signal; and the reference signal is used for phase noise estimation.
