Abstract
A random access method includes: when initiating random access, determining a measurement result of channel state information measurement reference signals (CSI-RS) of a plurality of beams; determining a target beam corresponding to a target CSI-RS having a measurement result greater than a preset threshold value; determining a target Synchronization Signal Block (SSB) corresponding to the target CSI-RS; determining a random access preamble and random access timing associated with the target SSB; and initiating random access on the target beam based on the random access preamble and the random access timing. A beam can be determined according to the measurement result of an CSI-RS, without determining the beam according to the measurement result of an SSB, thereby preventing the problem of user equipment (UE) being unable to select a suitable beam for random access due to a measurement result of an SSB not being obtained for a downlink BWP by UE.
