Abstract: The present disclosure provides a method and a device in nodes for wireless communication. A first node receives first control information, the first control information being used for indicating a first radio resource group, and the first control information being used for indicating a first priority; chooses a target radio resource from a target resource pool; and transmits a first radio signal in the target radio resource; the first radio signal corresponds to a second priority; if the second priority is lower than the first priority, the target resource pool is orthogonal with the first radio resource group. The method adopted in the present disclosure allows part of reserved resources to be released temporarily to meet abrupt service requirements, so as to achieve timely transmission of aperiodic and emergent service data, and thereby realizing efficient utilization of radio resources.

Abstract: 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 signaling, receives a first radio signal in a first time window, and then transmits a feedback on the first radio signal in a second time window. The first signaling is used for determining time-domain resources occupied by the first radio signal; a first time-domain deviation is a deviation in time domain between the second time window and the first time window; when the first signaling carries a first identifier, the first time-domain deviation is one of K1 first-type candidate deviation(s), and K1 is a positive integer; when the first signaling carries a second identifier, the first time-domain deviation is one of K2 second-type candidate deviation(s), and K2 is a positive integer.

Abstract: The disclosure discloses a method and device in a communication node for wireless communication. The communication node receives first information, and performs Q energy detections respectively in Q time sub-pools within a first sub-band, and if energy detected by each energy detection of the Q energy detections is lower than a first threshold, starts to transmit a first radio signal at a first time-instant; the first information is used to determine K candidate time-instant subsets; a target time-instant subset is one of the K candidate time-instant subsets, the first time-instant belongs to the target time-instant subset; a frequency-domain bandwidth of the first sub-band is used to determine the target time-instant subset out of the K candidate time-instant subsets, and frequency-domain resources occupied by the first radio signal belong to the first sub-band. The disclosure can improve access fairness.

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.
