The present disclosure provides a method and a device in a communication node for wireless communications. The communication node first receives first information; then receives a first signaling in X time windows; and transmits a first radio signal; wherein the first information is used to determine the X time windows, time-domain resources occupied by the first signaling are first time-domain resources, the X being a positive integer greater than 1; a start time for a transmission of the first radio signal is related to a first transmission timing adjustment and a second transmission timing adjustment; the first signaling is used to determine the first transmission timing adjustment, and the second transmission timing adjustment is related to a position of the first time-domain resources in the X time windows; the first information. The method in the present disclosure ensures uplink synchronous transmissions and improves link-level and system-level performance.

A method and device in a User Equipment (UE) and a base station low latency communication are disclosed. UE determines a first power, and transmits a first radio signal with the first power on a first carrier, and determines R power value(s), and transmits R low latency radio signal(s) on a second carrier with the R power value(s) respectively. When the first power and the R power value(s) have a value of zero, the UE drops the corresponding radio signals transmission. The present disclosure, according to carrying information of the first radio signal and the R low latency radio signal value(s) respectively, and time domain relations of occupied time intervals, determines the first power and the R power value(s), and then in a scenario that the UE supports both low latency communication and carrier aggregation, properly configures transmission powers of different carriers, and guarantees correct reception of uplink channels.

Embodiments of the present invention provide a method, device, and system for processing uplink interference. The method includes that after the first network device receives the information of the second UE sent by the second network device and receives the first uplink air interface data, when the first UE's When the uplink air interface data is parsed incorrectly, reconstruct the uplink air interface data of the second UE according to the information of the second UE, obtain the reconstructed uplink air interface data of the second UE, and eliminate the reconstruction of the second UE from the first uplink air interface data Uplink air interface data to obtain second uplink air interface data, and then analyze the second uplink air interface data according to the information of the first UE to obtain an analysis result of the first UE's uplink air interface data. Compared with the existing technology, the number of interactions between network devices is reduced, thereby reducing the bandwidth and delay requirements. When the bandwidth and delay of the interaction channel between network devices are constrained, the uplink transmission performance of the UE can also be improved.
