摘要： The present disclosure provides a method and a device in a User Equipment (UE) and a base station used for wireless communications. The UE receives Q1 indication information groups, which correspond to Q1 time slices respectively; then the UE receives Q2 reference signals respectively in Q2 time slices of a first frequency sub-band, and transmits first information; wherein a channel measurement for the Q2 reference signals is used to generate the first information. The present disclosure simplifies the process of channel detection on unlicensed spectrum by limiting the channel measurement for generating the first information in the Q2 time slices, and improves the flexibility of the base station to configure multiple reference signal combinations, so as to optimize the process of beam management on the unlicensed spectrum and improve the overall transmission efficiency and performance of the system.

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 present disclosure provides a method and a device in a User Equipment (UE) and a base station used for power saving. The UE first determines a first time-frequency resource set and K1 signature sequences, and then monitors the K1 signature sequences in the first time-frequency resource set; if any one of the K1 signature sequences is found in the first time-frequency resource set, the UE is woken up; the K1 signature sequences are used for generating K1 radio signals respectively; the first time-frequency resource set is one of K2 candidate time-frequency resource sets; and at least one of K1 and K2 is greater than 1. According to the present disclosure, the design of the K1 signature sequences effectively reduces the complexity of the UE detecting a wakeup signal, meanwhile, the number of UEs associated with one wakeup signal is flexibly configured.

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.
