    摘要: The disclosure provides a method and device in User Equipment (UE) and base station. The UE receives first configuration information, and then receives a first radio signal and a second radio signal in first time domain resources and second time domain resources respectively. A first bit block is used for generating the first radio signal and the second radio signal. The first configuration information is applied to the first radio signal and the second radio signal. According to the disclosure, the first configuration information is used for configuring both the first radio signal and the second radio signal, and the first radio signal and the second radio signal are received on different time domain resources respectively; therefore, data corresponding to one same bit block can be transmitted through different modes, air interface resources can be fully utilized and the overall spectrum efficiency of the system can be improved.

    摘要: The present disclosure provides a method and a device in a first node for wireless communication. The first node first performs a monitoring on first-type signalings, in which K1 first-type signalings are detected; and then transmits a first radio signal in a first time-frequency resource set; each of the K1 first-type signalings is associated to the first time-frequency resource set; a first signaling is a last first-type signaling of the K1 first-type signaling; the first radio signal is used for determining the receiving of first-type signaling(s) associated to the first time-frequency resource set before the first signaling; or is used for determining the decoding of bit blocks scheduled by the K1 first-type signalings. With the above-mentioned designs, the present disclosure manages to address missed detection of sidelink scheduling signaling caused when a data receiver sends NACK-only feedback in V2X, thereby further improving the entire system performance.

    摘要: The disclosure provides a method and a device in a User Equipment (UE) and a base station for wireless communication. UE transmits first information, the first information being used for determining a first reference signal, then the UE receives second information in a first frequency subband in a first time window and detects third information in a second frequency subband in a second time window; the first time window is related to time-domain resources occupied by the first information; a first antenna port is used for transmitting the first reference signal, each antenna port used for transmitting the second information is spatially related to the first antenna port, and each antenna port used for transmitting the third information is spatially related to the first antenna port. The disclosure simplifies the processes of beam link failure judgement and beam management for a UE, thereby improving the overall performance of the system.

    摘要: The present disclosure provides a method and a device in a node used for wireless communications. A first node performs channel detection in a first time window to determine a candidate time-frequency resource pool and then receives a first signaling, the first signaling being used to determine a first time-frequency resource set; and transmits a target signaling, the target signaling being used for reserving a candidate time-frequency resource set; the candidate time-frequency resource pool comprises the candidate time-frequency resource set; the candidate time-frequency resource set is reserved for transmission of a first TB; the channel detection is related to the first TB's type. Through designing the present disclosure manages to associate time-frequency resources covered by the channel detection with the first TB's type or duration, thus enhancing the performance of channel detection, which further optimizes sidelink transmission performance and efficiency.

    摘要: The disclosure provides a method and a device in a User Equipment (UE) and a base station for wireless communication. The UE receives first information, and transmits a first radio signal using a first antenna port group; the first information is used for indicating a first offset set, and the first offset set includes K1 first-type offset(s); time domain resources occupied by the first radio signal start from a first time, a time interval between the first time and a second time is equal to a target offset; the UE selects the target offset from the K1 first-type offset(s) autonomously. The disclosure establishes a relationship between the first offset set and the first antenna port group, thus improving opportunities of beamforming based grant-free data transmission on unlicensed spectrum and reducing probability of collision, thereby improving spectrum efficiency and overall performances of the system.

    摘要: The present disclosure discloses a method and a device in nodes used for wireless communications. A first node first receives a first radio signal and a second radio signal; and then determines that transmitting power of first control information in a first time window is a first power value and transmitting power of second control information in a second time window is a second power value; and transmits the first control information in the first time window with the first power value; the first power value is unrelated to the second power value, and the second power value is relevant to whether the first time window overlaps with the second time window. The present disclosure designs power allocation priorities of first control information and second control information to optimize both transmission performance and efficiency of a feedback channel in sidelink.

    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.
