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.

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: 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.

Abstract: The present disclosure provides a method and device in a node for wireless communications. A first node receives a first information block; receives a first signaling; and as a response to a behavior of receiving the first signaling, stops a first behavior; the first information block indicates a first reference signal set, and the first reference signal set comprises at least one reference signal; the first signaling comprises DCI, the first signaling is used to determine a first transmission state, and the first transmission state indicates a first reference signal; the first transmission state is applied to a first channel and a second channel. The above method temporarily stops the beam failure discovery and/or recovery request for the mismatched reference signals when a reference signal configured by RRC for beam failure monitoring does not match a beam used by a downlink control channel, thus avoiding the waste of resources.
