摘要： The disclosure provides a method and a device in a node for wireless communication. A first node receives a first signal and a second signal, and the first node transmits a first information block and a second information block in a first time window. The first information block and the second information block are used for determining whether the first signal and the second signal are correctly received respectively; transmit power values of physical layer channels carrying the first information block and the second information block are both a first power value. Through the design in the disclosure, a transmit power of a feedback channel on a sidelink is associated with a priority; and when multiple feedback channels are transmitted in one same time window, a proper transmit power can be determined to optimize performances of the feedback channels on the sidelink.

摘要： The disclosure provides a method and device used for node in wireless communication. The first node first receives a first reference signal and a second reference signal, then determines a first power within a range not greater than a first maximum power, and finally transmits a first radio signal with the first power; wherein the first maximum power is related to a measurement result against the first reference signal and is not related to a measurement result against the second reference signal. Through determining an upper limit of a transmitting power on a sidelink using a measurement result against a cellular network link, the disclosure can reduce interferences to the cellular network while ensuring the sidelink performance, and can optimize the transmitting power on the sidelink to reduce the power consumption of the terminal, thereby improving the overall performance of the system.

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： A method and device for power adjustment in a user equipment and a base station are disclosed in the present disclosure. The user equipment receives first information which is used to trigger a first operation, and then receives K piece(s) of target information and transmits a first wireless signal. A transmission power value of the first wireless signal is a first power value; the first power value is irrelevant to all piece(s) of target information received prior to triggering the first operation. The K piece(s) of target information is(are) received after triggering the first operation. The sum of K power offset value(s) is used to determine the first power value. The K power offset value(s) are respectively indicated by the K piece(s) of target information.

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.
