Electronic device, communication method and storage medium

An electronic device on side of a UE, comprising:

• a processing circuitry configured to:
• receive, from a base station, a dynamic signaling including beam indication information on a first beam which is determined to be used for a first transport channel between the UE and the base station;
• update a beam for the first transport channel to the first beam;
• and
• in a case where the updating of the beam for the first transport channel is successful, update a beam for a second transport channel and/or a reference signal between the UE and the base station to the first beam.

A communication method, comprising:

• determining a first beam for a first transport channel between a base station and a UE;
• sending, to the UE, a dynamic signaling including beam indication information on the first beam, such that a beam for the first transport channel is updated to the first beam;
• and
• in a case where the updating of the beam for the first transport channel is successful, updating a beam for a second transport channel and/or a reference signal between the base station and the UE to the first beam.
