Abstract: This application provides a measurement method and apparatus, and relates to the field of communications technologies. The method includes: measuring a currently camped cell in Δt, to obtain {Si|i is a positive integer, i≤N}; if any Si in {Si|i is a positive integer, i≤N} satisfies that SREF−Si greater than or equal to a first threshold, updating SREF so that SREF is equal to SN; and measuring one or more neighboring cells of the currently camped cell if SREF−Si is greater than or equal to the first threshold. To be specific, when determining that a cell state variable in Δt is always less than a cell state reference variable, a terminal may start measurement on the neighboring cells, and update the cell state variable from SREF to a cell state variable SN obtained through the last measurement in Δt.

Abstract: An inter-frequency cell measurement operation in described. The operation includes: performing, by a terminal, when receiving a measurement command of a network side device, inter-frequency cell measurement, in different cases, based on the time specified in different measurement time parameters or based on measurement time parameters corresponding to the information about an inter-frequency band. As different measurement time parameters specify different time actually used for measurement. Not only can an inter-frequency cell that meets a measurement event be measured, but also the time for measurement by the terminal can be reduced, thereby reducing the power consumption of the terminal and enhancing the performance of the terminal.

Abstract: The present invention relates to a beam-based multi-connection communication method, a terminal device, and a network device. In the beam-based multi-connection communication method, after a terminal device establishes an RRC connection to a terminal, a base station or the terminal device may trigger a random access process to establish at least one beam connection, or when the terminal device is idle, establishment of at least one beam connection may be completed as a random access process is performed, to reduce system overheads for performing beam communication restoration by the terminal device after communication on a single beam is interrupted, and avoid a data transmission interruption between the base station and the terminal device, thereby ensuring normal communication between the base station and the terminal device.

Abstract: Embodiments of the present disclosure provide a communication method, and a communications apparatus and system. User equipment can communicate with the network device by using a plurality of beams, the plurality of beams include a first beam and at least one second beam, the first beam is a serving beam used by the user equipment to listen to control information, and the second beam is a beam other than the serving beam. The method includes: determining, by the user equipment, that the serving beam is blocked; and obtaining, by the user equipment, a first message from the network device by using the first beam or the second beam. According to the method, the UE may determine that the serving beam is blocked, and further obtain the first message sent by the network device, thereby eliminating an adverse effect caused by the blocking of the serving beam. Correspondingly, the network device may also determine that the serving beam is blocked, and further send the first message, thereby eliminating an adverse effect caused by the blocking of the serving beam.
