Abstract: The disclosure provides a method and device in communication node used for wireless communication. A first node receives a first signaling, transmits a first bit block set in a first air interface resource block, receives a second signal in a second air interface resource block, and transmits a third signal in a third air interface resource block. The first signaling is used for determining the first air interface resource block, and the first air interface resource block is used for determining the second air interface resource block; the second signal and the third signal indicate whether the first bit block set is correctly received respectively; the first signaling indicates a first time interval. The above method simplifies the design of downlink signalings for allocation of sidelink resources and reduces signaling overheads.

Abstract: The present disclosure provides a method and device in nodes for wireless communication. A first node receives first information; and receives a first signaling. The first information is used for determining K resource blocks; the K resource blocks respectively correspond to K reference-signal resource groups; any reference-signal resource in the K reference-signal resource groups corresponds to one of M first-type indexes; the first signaling is used for activating a first index in the M first-type indexes; a first resource block is any of the K resource blocks, a first reference-signal resource is used for determining a spatial relation of the first resource block, and the first reference-signal resource is one reference-signal resource corresponding to the first index in a reference-signal resource group corresponding to the first resource block. The above method employs information selected by TRP/panel, thus reducing a signaling overhead and delay of beam management.

Abstract: 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.

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.

Abstract: The present disclosure provides a method and a device in a node used for wireless communications. A first node receives a first reporting configuration and a first signaling; and transmits a first information block. The first signaling indicates a first transmission configuration state; the first information block comprises a reporting for the first reporting configuration; the first reporting configuration comprises N resource configurations; the N resource configurations respectively correspond to N first-type indexes; the first transmission configuration state corresponds to a first index; the first index is used to determine a first resource configuration; a measurement on reference signal resource(s) only in the first resource configuration among the N resource configurations is used to generate the first information block. The above method ensures that a TCI state of reference signals constantly matches with configuration information with the beams being dynamically updated.

Abstract: The present disclosure discloses a method and a device in a node for wireless communication. The first node transmits first information; receives second information; transmits a first bit-block set on a first time-frequency-resource block; transmits or drops transmission of a third bit-block set on a third time-frequency-resource block; and receives a second signal on a fourth time-frequency-resource block; the first information is used for indicating that the fourth time-frequency-resource block is associated with the third time-frequency-resource block; the second information indicates that the fourth time-frequency-resource block is associated with the first time-frequency-resource block; the second signal is used for indicating whether a target bit-block set is correctly received; when the first node transmits the third bit-block set on the third time-frequency-resource block, the target bit-block set is the third bit-block set, otherwise the target bit-block set is the first bit-block set.
