Beam determining method and apparatus, and storage medium

A beam determining method, applied to a terminal, comprising:

• acquiring beam configuration information, wherein the beam configuration information at least comprises parameters configured to indicate receiving beams corresponding to at least two of N repeated transmissions of a downlink channel, where N is a natural number;
• and
• determining receiving beams corresponding to the at least two of the N repeated transmissions according to the beam configuration information,
• wherein the receiving beams corresponding to the at least two of the N repeated transmissions of the downlink channel are all activated;
• the beam configuration information further comprises:
• time granularity configured to indicate beam switching between candidate beams, wherein the time granularity is determined by at least one of:
• granularity of frequency hopping,
• granularity of variation of a pre-coded matrix in a time domain,
• granularity of redundant version (RV) transformation, or
• a number of repeated transmissions for the terminal;
• and
