Abstract: A beam training method includes: determining, by a terminal device, to send n pilot sequences to a network device by using n beams in n timeslots within one uplink beam training period, where the n pilot sequences are at least partially different, and n is a positive integer greater than 1; and sending, by the terminal device, the determined n pilot sequences to the network device by using the n beams in the n timeslots within the uplink beam training period.

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: Embodiments of the present application relate to a method and apparatus for implementing high-frequency communication. The method includes: receiving, by a high-frequency base station, a scan request message sent by a base station originally connected to user equipment (UE); sending, by the high-frequency base station, a scan acknowledgment message to the base station originally connected to the UE, receiving, by the high-frequency base station, information about the UE sent by the base station originally connected to the UE; and scanning the UE, by the high-frequency base station, according to the information about the UE, so as to re-establish a high-frequency connection between the UE and the high-frequency base station.

Abstract: Embodiments of the present application relate to the field of communications technologies, and provide a wireless communication method, a device, and a system, so as to cancel or reduce inter-cell interference, to a terminal, between neighboring cells. The method includes: sending, by a terminal, uplink information to a first network side device in a first time period; and receiving, by the terminal in a second time period, downlink information sent by a second network side device, where the first time period and the second time period are a same time period. The embodiments of the present application are used for wireless communication.
