A method and a device in a User Equipment (UE) and a base station for wireless communication are disclosed. The UE transmits a first radio signal including M first-type radio signals transmitted by M antenna port groups and a second-type radio signal transmitted by a target antenna port group; the second-type radio signal carries uplink control information; and at least one of the following is used for determining the target antenna port group from the M antenna port groups: a first antenna port group, wherein a reception for a radio signal transmitted by the first antenna port group is used for generating the uplink control information; M time-frequency resources, wherein the M first-type radio signals are scheduled by M downlink signalings respectively, and the M downlink signalings are searched for in the M time-frequency resources respectively; and, first information, wherein the first information indicates explicitly the target antenna port group.

Method and device in UE and base station USD for wireless communication

The present disclosure provides a method and a device in a User Equipment (UE) and a base station for wireless communication. The UE transmits first information including at least the former two of {K first-type indexes, K1 first-type indexes, K first-type numerical values}. The K1 first-type indexes are a subset of the K first-type indexes. The K first-type indexes are used for determining K antenna port groups. The UE receives simultaneously radio signals from K1 antenna port groups. The K1 first-type indexes are used for determining the K1 antenna port groups. The K first-type numerical values are used for determining K channel qualities. The K1 first-type indexes include at least one given first-type index, and a position of the given first-type index in the K first-type indexes is used for determining whether an antenna port group corresponding to the given first-type index belongs to the K1 antenna port groups.
