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. A new 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 User Equipment (UE) and a base station for wireless communication. The UE receives first information, and transmits a first radio signal using a first antenna port group; the first information is used for indicating a first offset set, and the first offset set includes K1 first-type offset(s); time domain resources occupied by the first radio signal start from a first time, a time interval between the first time and a second time is equal to a target offset; the UE selects the target offset from the K1 first-type offset(s) autonomously. The disclosure establishes a relationship between the first offset set and the first antenna port group, thus improving opportunities of beamforming based grant-free data transmission on unlicensed spectrum and reducing probability of collision, thereby improving spectrum efficiency and overall performances of the system.

摘要： The present disclosure discloses a method and a device in nodes used for wireless communications. A first node first receives a first radio signal and a second radio signal; and then determines that transmitting power of first control information in a first time window is a first power value and transmitting power of second control information in a second time window is a second power value; and transmits the first control information in the first time window with the first power value; the first power value is unrelated to the second power value, and the second power value is relevant to whether the first time window overlaps with the second time window. The present disclosure designs power allocation priorities of first control information and second control information to optimize both transmission performance and efficiency of a feedback channel in sidelink.
