Abstract: The disclosure provides a method and device in User Equipment (UE) and base station for wireless communication. The UE receives Q1 first-type information groups, and transmits or receives a first radio signal in a first time-frequency resource according to a configuration of a first information group; the first information group is one of the Q1 first-type information groups; a frequency domain position of the first time-frequency resource is used for determining the first information group from the Q1 first-type information groups; each of the Q1 first-type information groups includes at least one of relevant information to a subcarrier spacing.

The UE can select a beam direction corresponding to a downlink channel according to its measurement, thereby improving efficiency and performances of downlink transmission.

The UE receives a first signaling and a second signaling; and transmits first reporting information in a target time-frequency resource. The first signaling and the second signaling are respectively used to determine a first antenna port group and a second antenna port group; a first antenna port group and a second antenna port group are respectively applicable to a first time-frequency resource and a second time-frequency resource; at least one of the following is used to determine the target time-frequency resource from the first time-frequency resource and the second time-frequency resource: the first antenna port group, the second antenna port group. When uplink data and control information for different TRPs conflict in time domain, the above method guarantees the reception quality of the two and avoids an extra delay.

The UE first receives a first radio signal, and then monitors a first signaling set in a first time-frequency resource set; the first radio signal is used for determining that physical layer signaling(s) corresponding to the first signaling set may occupy any of X1 first-type RE sets.

Abstract: The disclosure provides a method and a device in a node for wireless communication. A first node first receives a first bit field and Q second-type bit field(s), and then transmits L radio signal(s) at a first power value; the first bit field is used for determining a first reference signal resource set; each of the Q second-type bit field(s) indicates one power offset; the first power value is only related to power offsets indicated by all second-type bit fields among the Q second-type bit field(s) that correspond to a first index, and the first index is one of K1 indexes associated to the first reference signal resource set; and the first index is related to the L reference signal resource set(s). Multiple times of repetition based uplink transmissions employ a uniform power control mechanism under multiple beams, which reduces hardware requirements at terminal side and improves transmission performance.
