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: A first node receives a first signaling and transmits a first signal. The first signaling indicates scheduling information of the first signal; the first signal comprises a first sub-signal and a second sub-signal; a first field and a second field of the first signaling are respectively used to determine antenna ports for transmitting the first sub-signal and the second sub-signal; a payload of bit(s) in the second field of the first signaling is related to K1 candidate integers; the relationship between the payload of the bit(s) in the second field of the first signaling and the K1 candidate integers is related to whether a time-domain resource occupied by the first sub-signal overlaps with a time-domain resource occupied by the second sub-signal. The above method meets different requirements for the number of bits in the first field and the second field for different multiplexing methods.

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.
