Abstract: 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.

Abstract: The present disclosure provides a method and a device in a communication node for wireless communications. The communication node first receives first information, the first information being used to determine a target time-frequency resource pool; and then monitors a first signaling; after that, when the first signaling is detected, the communication node receives a first radio signal; a first code block is used to generated the first radio signal; time-frequency resources occupied by the first signaling comprise a first time-frequency resource, while time-frequency resources occupied by the first radio signal comprise a second time-frequency resource; whether the first radio signal can be excluded from being used for combined decoding for the first code block is dependent on whether the first time-frequency resource belongs to the target time-frequency resource pool. The present disclosure manages to improve the flexibility of buffer configurations.

Abstract: The present disclosure provides a method and a device in a communication node for wireless communications. The communication node in the present disclosure first receives first information, and then transmits a first radio signal; a length of a time interval between a start time for transmitting the first radio signal and a first reference time is equal to a sum of a first timing adjustment and a second timing adjustment, the first timing adjustment being one of X candidate timing adjustments, the X being a positive integer greater than 1; the second timing adjustment is used for determining a transmission timing of a radio signal transmitted before the first radio signal in time domain; a transmitter of the first radio signal determines the first timing adjustment out of the X candidate timing adjustments by itself. The present disclosure can improve uplink synchronization performance.

Abstract: The present disclosure provides a method and a device in a UE and a base station for wireless communication. The UE receives a first signaling in a first resource element set and a first radio signal. The first resource element set determines a first information set out of M information sets; wherein M is equal to 2; the first resource element set comprises a positive integer number of resource element(s); any information set of the M information sets comprises a positive integer number of information element(s); any information element in the M information sets is a transmission configuration indication state; any information element of the integer number of information element(s) comprises a first type index and a second type index set, a second type index set comprises one second type index or multiple second type indices. The above method helps reduce overhead for scheduling signaling.

Abstract: The present disclosure provides a method and a device in a User Equipment (UE) and a base station for wireless communications. A UE receives first information, the first information being used for indicating M DCI blind decoding(s); monitors a first-type radio signal respectively on each of S sub-band(s) in a first time-domain resource; and performs at most M1 DCI blind decoding(s) of the M DCI blind decoding(s) on the S sub-band(s) in the first time-domain resource. Herein, the first-type radio signal detected on the S sub-band(s) is used for determining the M1 DCI blind decoding(s) out of the M DCI blind decoding(s). The above method allows the base station to make dynamic adjustments to the UE's blind decoding on PDCCH resources according to LBT results, ensuring that sufficient PDCCH resources are available and not too many PDSCH resources are preempted, and that excessive blind decodings can be avoided.
