Abstract: The present disclosure provides method and device in a User Equipment (UE) and a base station used for wireless communication. 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.

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.

The UE receives a first signaling, the first signaling being used to determine a first time-frequency resource; receives a second signaling, the second signaling being used to determine a second time-frequency resource; and transmits a first bit block in the first time-frequency resource, or, transmits a first bit block in the second time-frequency resource. Time domain resource occupied by the first time-frequency resource and time domain resource occupied by the second time-frequency resource are non-orthogonal; the first signaling carries a first identifier or a second identifier; whether the first signaling carries the first identifier or the second identifier is used to determine whether the first bit block is transmitted in the first time-frequency resource or transmitted in the second time-frequency resource.

Abstract: The disclosure provides a method and a base station device for wireless communication. A RRC signaling having reference signal resource set(s) and second-type bit field(s) is transmitted, each of the second-type bit field(s) for indicating one power offset and corresponding to one of a plurality of indexes related to the reference signal resource set(s), the second-type bit field(s) including only one second-type bit field corresponding to a first index of the indexes. A PHY signaling having a first bit for determining a first reference signal resource set associated to the plurality of indexes is transmitted. Then a first radio signal at a first power value that is only related to power offsets indicated by all second-type bit fields among the second-type bit field(s) that correspond to the first index is received, the first radio signal being Quasi Co-located with one of the reference signal resource set(s).

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 disclosure establishes an association between the frequency domain position of the first time-frequency resource and the first information group, thereby simplifying the reception of the first-type information group, improving the flexibility of scheduling of frequency domain resources on unlicensed spectrum, and improving the overall performance of the system.

Abstract: The disclosure provides a method and a device in a User Equipment (UE) and a base station for multi-antenna transmission. The UE transmits a first radio signal in a first time interval, and receives a second radio signal in a second time interval; and then monitors a third radio signal in a third time interval. The first radio signal includes first information, and the second radio signal includes second information. Target information is used for receiving the third radio signal. A time-domain position of the second time interval is used for determining whether the target information is the first information or the second information.
