Abstract: 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.

Abstract: A first node receives N CSI configuration information; updates a CSI reporting in a first CSI reporting subset; transmits a first information block; the N CSI configuration information is respectively used to determine N CSI reportings, and the first CSI reporting subset is a subset of the N CSI reportings; the first information block comprises at least one CSI reporting of the N CSI reportings; any Type I CSI reporting in the N CSI reportings corresponds to a first-type integer, and any Type II CSI reporting in the N CSI reportings corresponds to a second-type integer, the N CSI reportings respectively correspond to N priorities, and the N priorities are used to determine a number of CSI reporting(s) comprised in the first CSI reporting subset. The above method configures different processing units for CSI reportings with different CSI computing power requirements, thus avoiding the waste of computing power.

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 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 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: A first node receives a first signaling; transmits a first signal in a first transmission occasion in a first cell group; transmits or drops transmitting a second sub-signal in a second transmission occasion in a second serving cell. The first signaling is used to determine a first time-domain resource; transmit power of the first signal is equal to a first power value; transmit power of a second signal is equal to a second power value, and the second signal comprises the second sub-signal; whether a sum of the first power value and the second power value minus a first maximum transmit power is greater than a first threshold is used to determine whether the second sub-signal is transmitted in the second transmission occasion in the second serving cell. The above method satisfies the demands of different duplex modes for uplink transmit power.

Abstract: A method and a device in a node for wireless communications. A first node monitors or drops monitoring a first signal in a first resource block; and transmits a second signal in a second resource block. The second resource block corresponds to a first index; the first resource block is reserved for a HARQ-ACK for a bit block set transmitted in a third resource block; when a first condition set is fulfilled, a spatial relation of the second signal is unrelated to the first index; when the first condition set is unfulfilled, the first index is used for determining the spatial relation of the second signal; the first condition set relates to whether the first signal is conveyed in the first resource block. The method above provides an easy implementation of beamforming in a V2X system, which optimizes gains of beamforming and also prevents complicated signaling interaction.
