Antenna beam management method and related device

A method for managing an antenna beam, comprising:

• receiving, by a base station, downlink beam related information transmitted by a UE;
• determining, by the base station, at least one first downlink transmission beam based upon the downlink beam related information;
• transmitting, by the base station, a notification related to the first downlink transmission beam to the UE, so that the UE determines at least one first downlink reception beam based upon the notification, wherein the notification comprises an indicator for the UE to determine the at least one first downlink reception beam;
• and
• transmitting, by the base station, a downlink signal to the UE using the first downlink transmission beam.

A UE, comprising a processor, a memory, and a transceiver, wherein the transceiver receives and transmits data under a control of the processor, the memory stores preset program, and the processor reads and executes the program in the memory:

• to transmit downlink beam related information of the UE to a base station, so that the base station determines at least one first downlink transmission beam based upon the downlink beam related information;
• to receive a notification related to the first downlink transmission beam, transmitted by the base station;
• to determine at least one first downlink reception beam based upon the notification;
• and to receive a downlink signal using the at least one first downlink reception beam;
• wherein the notification comprises an indicator for the UE to determine the at least one first downlink reception beam.
