摘要： The present disclosure provides a method and device in a node for wireless communications. A first node transmits a first signal, and the first signal is used for random access; in response to transmitting the first signal, monitors a first-type channel in a first resource set to detect a first-type signaling; monitors the first-type channel in a second resource set to detect a second-type signaling; receives a target signaling, the target signaling is used to determine a target time; and when the target signaling is a third-type signaling, in response to receiving the target signaling, stops monitoring the first-type channel in the first resource set after the target time; when the target signaling is a fourth-type signaling, in response to receiving the target signaling. The above method can quickly recover a beam for unicast service and a beam for PTM/multicast groupcast service after beam failure.

摘要： 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.

摘要： The present disclosure discloses a method and device in UE and base station used for wireless communications. A UE transmits a first radio signal, the first radio signal indicating a first reference signal out of M reference signals; and monitors a first signaling in each of W time-frequency resource block(s). Herein, at least one reference signal of the M reference signals is transmitted by a first serving cell, and the first serving cell is not added by the UE; the UE assumes that a transmission antenna port of the first signaling is Quasi-Co-Located with a transmission antenna port of the first reference signal; W is a positive integer, and M is a positive integer greater than 1. Such method can be employed to avoid delay and service interruption brought about by cell handover.

摘要： The present disclosure a method and a device in a UE and a base station used for wireless communications. A first node performs Q energy detection(s) on a first sub-band to obtain Q detection value(s); and determines based on the Q detection value(s) that a first radio signal is transmitted on the first sub-band at a first instant of time; performs P energy detection(s) on a second sub-band to obtain P detection value(s); and transmits or drops transmitting a second radio signal on the second sub-band at the first instant of time; each of the Q energy detection(s) is associated with a first antenna port group; when each of the P energy detection(s) is associated with the first antenna port group, the P is P1, otherwise the P is P2. The present disclosure is advantageous in ensuring fairness in the contention for spectrum occupancy in multicarrier-supporting Unlicensed Spectrum communications.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： The present disclosure provides a method and a device in a UE and a base station used for wireless communications. The UE receives a first signaling, a second signaling and a third signaling, and receives or transmits a first radio signal in a first frequency sub-band. The first signaling is used for determining M information sets, any of the information sets comprises a positive integer number of information element(s), any information element comprises a first-type index and a second-type index set, the second-type index set comprises one second-type index or more second-type indices. The second signaling is used for determining a first information set out of the M information sets. The third signaling is associated with the second signaling. The above method reduces the signaling overhead of beam management and indication in each bust on the Unlicensed Spectrum.
