Method and device in ue and base station for wireless communication

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

• transmitting first information, the first information being used to indicate N Channel Status Information (CSI) Reporting Settings, the N CSI Reporting Settings respectively being associated with N radio resources, and N being a positive integer greater than 1;
• transmitting second information, the second information being used to indicate J radio resource(s), and J being a positive integer;
• and
• receiving M piece(s) of CSI in a first radio resource, the M piece(s) of CSI respectively corresponding to M CSI Reporting Setting(s) among the N CSI Reporting Settings, the first radio resource being one of the J radio resource(s), and M being a positive integer no greater than the N;
• wherein the first radio resource corresponds to a first antenna port group, the N radio resources respectively correspond to N antenna port groups, and whether the N antenna port groups are spatially associated with the first antenna port group is used to determine the M CSI Reporting Setting(s) out of the N CSI Reporting Settings.

A UE for wireless communications, comprising:

• a first receiver, which receives first information, the first information being used to indicate N Channel Status Information (CSI) Reporting Settings, the N CSI Reporting Settings respectively being associated with N radio resources, and N being a positive integer greater than 1;
• and receives second information, the second information being used to indicate J radio resource(s), and J being a positive integer;
• and
• a first transmitter, which transmits M piece(s) of CSI in a first radio resource, the M piece(s) of CSI respectively corresponding to M CSI Reporting Setting(s) among the N CSI Reporting Settings, the first radio resource being one of the J radio resource(s), and M being a positive integer no greater than the N;
• wherein the first radio resource corresponds to a first antenna port group, the N radio resources respectively correspond to N antenna port groups, and whether the N antenna port groups are spatially associated with the first antenna port group is used to determine the M CSI Reporting Setting(s) out of the N CSI Reporting Settings.
