摘要： A method and a device in a UE and a base station for wireless communication are disclosed. The UE monitors a first sequence in a first time window. If the first sequence is detected in the first time window, performs a blind detection of a first signaling on K1 alternative RE set(s); the first signaling occupies one of K1 alternative RE set(s) in time-frequency domain, each RE included in K1 alternative RE set(s) belongs to an alternative time-frequency resource pool in a second time window in time domain. The first sequence is used for determining a start time of the alternative time-frequency resource pool in the second time window. The disclosure determines the start time of the alternative time-frequency resource pool by using the first sequence, increasing transmitting opportunities of control signalings without increasing number of times of blind detections, improving spectrum efficiency and overall system performance on unlicensed spectrum.

摘要： The disclosure provides a method and a device in a User Equipment (UE) and a base station for multi-antenna communication. The UE first monitors a first signaling set in a first time-frequency resource set, then transmits a first radio signal, and finally monitors a second signaling set and a third signaling set in a second time-frequency resource set and a third time-frequency resource set respectively; the first radio signal is used for triggering a monitoring of the second signaling set; and the first radio signal is used for determining that a number of maximum blind decoding times for the third signaling set in the third time-frequency resource set changes from X1 to X3. Anew blind decoding mechanism is designed through transmitting the first radio signal, thus the number of blind decoding times of the UE is reassigned, the reception complexity and power consumption of the UE are reduced.

摘要： 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.
