Method and device in ue and base station used for wireless communication

A method in a base station for wireless communications, comprising:

• transmitting N groups of first configuration information, each group of the N groups of first configuration information being used for determining a corresponding antenna port group set, N being a positive integer greater than 1;
• transmitting Q piece(s) of indication information, Q being a positive integer;
• and
• transmitting first control information, the first control information being associated with first information, the first information being one of the Q piece(s) of indication information;
• wherein the first information is used for determining first target configuration information out of the N groups of first configuration information;
• the first target configuration information is one group of the N groups of first configuration information;
• the first target configuration information is used for determining a first antenna port group set, the first antenna port group set is composed of one or more antenna port groups, of which each antenna port group is composed of one or more antenna ports;
• a first reference antenna port group is an antenna port group in the first antenna port group set, a measurement on the first reference antenna port group is used for receiving the first control information.

A UE for wireless communications, comprising:

• a first receiver, receiving N groups of first configuration information, each group of the N groups of first configuration information is used for determining a corresponding antenna port group set, N is a positive integer greater than 1;
• receiving Q piece(s) of indication information, Q being a positive integer;
• receiving first control information, the first control information being associated with first information, the first information being one of the Q piece(s) of indication information;
• wherein the first information is used for determining first target configuration information out of the N groups of first configuration information;
• the first target configuration information is one group of the N groups of first configuration information;
• the first target configuration information is used for determining a first antenna port group set, the first antenna port group set is composed of one or more antenna port groups, of which each antenna port group is composed of one or more antenna ports;
• a first reference antenna port group is an antenna port group in the first antenna port group set, a measurement on the first reference antenna port group is used for receiving the first control information.
