Abstract
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.
