A method and a device are provided in a User Equipment (UE) and a base station for wireless communication. The UE receives a first signaling and transmits a first radio signal. The first signaling includes K first field(s) and K second field(s), the K first field(s) is(are) used for determining K first-type vector(s) respectively, and the K first-type vector(s) is(are) one-to-one corresponding to K second-type vector group(s) or K second field(s); a correlation between any one second-type vector in each second-type vector group(s) and a corresponding first-type vector is related to a corresponding second field; the first radio signal includes a second radio signal and a third radio signal; the K first-type vector(s) and the K second-type vector group(s) are used for determining multi-antenna related transmissions of the second radio signal and the third radio signal respectively; the second radio signal and the third radio signal occupy orthogonal frequency-domain resources.
