摘要： The disclosure provides a method and a device in a User Equipment (UE) and a base station for wireless communication. UE transmits first information, the first information being used for determining a first reference signal, then the UE receives second information in a first frequency subband in a first time window and detects third information in a second frequency subband in a second time window; the first time window is related to time-domain resources occupied by the first information; a first antenna port is used for transmitting the first reference signal, each antenna port used for transmitting the second information is spatially related to the first antenna port, and each antenna port used for transmitting the third information is spatially related to the first antenna port. The disclosure simplifies the processes of beam link failure judgement and beam management for a UE, 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 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. The UE transmits M2 first type radio signal(s) in M2 time block(s) of M1 time blocks respectively, and transmits a second type radio signal; the second type radio signal is used to determine at least the former of the M2 time block(s) and M2 first type carrier(s); the M2 first type radio signal(s) is(are) transmitted on the M2 first type carrier(s) respectively; a first bit block is used to generate the M2 first type radio signal(s); the present disclosure designs the second type radio signal, which helps the base station determine a position of a carrier where transmission is actually performed and corresponding time block when narrowband UE performs uplink data transmission on unlicensed frequency spectrum. This further streamlines base station reception and improves uplink transmission performance.

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.

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 a first reference signal in a first time-frequency resource set, and transmits first information and second information; the first information indicates the first time-frequency resource set from Q candidate time-frequency resource sets; at least two of the Q candidate time-frequency resource sets correspond to a first type and a second type respectively; a channel measurement for the first reference signal is used for determining the second information; and a type of channel state information included in the second information is related to a type corresponding to the first time-frequency resource set. A relationship is established between the type corresponding to the first time-frequency resource set and the content of the second information, thus improving the feedback precision and efficiency of channel state information.
