    摘要: The present disclosure provides a method and a device in a User Equipment (UE) and a base station for wireless communications. The UE receives a first signaling, and then transmits a first radio signal in a first subband. The first signaling comprises scheduling information of the first radio signal; the first signaling comprises a first field, the first field in the first signaling being used for determining a first reference-signal-resource group or the first subband, the first reference-signal-resource group comprising K1 first-type reference signal resource(s); whether the scheduling information of the first radio signal is non-codebook-based or codebook-based is related to the first field in the first signaling; the first subband is one of M subbands. The above method allows UE to flexibly switch between non-codebook-based and codebook-based uplink transmissions, thus avoiding the problem that a single uplink transmission mode cannot work on Unlicensed Spectrum.

    摘要: A method and a device in a UE and a base station for wireless communication are disclosed. The UE monitors a first sequence in a first time window. If the first sequence is detected in the first time window, performs a blind detection of a first signaling on K1 alternative RE set(s); the first signaling occupies one of K1 alternative RE set(s) in time-frequency domain, each RE included in K1 alternative RE set(s) belongs to an alternative time-frequency resource pool in a second time window in time domain. The first sequence is used for determining a start time of the alternative time-frequency resource pool in the second time window. The disclosure determines the start time of the alternative time-frequency resource pool by using the first sequence, increasing transmitting opportunities of control signalings without increasing number of times of blind detections, improving spectrum efficiency and overall system performance on unlicensed spectrum.

    摘要: The present disclosure discloses a method and a device used for wireless communication in a User Equipment (UE) and a base station. The UE receives a first radio signal and a second radio signal, and then transmits K first-type bit sequence(s) respectively in K time-frequency resource(s). A first bit block is used for indicating whether the first radio signal is correctly received, the first bit block comprises a positive integer number of bit(s); a second bit block comprises feedback to the second radio signal, the second bit block comprises a positive integer number of bit(s); each first-type bit sequence of the K first-type bit sequences comprises a positive integer number of bit(s); the first bit block and the second bit block are used for generating each first-type bit sequence of the K first-type bit sequence(s); the K is a positive integer. The above method improves transmission reliability of control information.

    摘要: The disclosure provides a method and a device in a communication node for wireless communication. The communication node performs signaling monitoring in a first time window, X1 signaling(s) being detected in the signaling monitoring process, determines Y1 candidate resource set(s) from a first candidate resource pool, transmits a first signaling, and receives first feedback information in a target resource set, the target resource set being one of the Y1 candidate resource set(s); the X1 signaling(s) is(are) used for determining Y2 candidate resource set(s), any one of the Y2 candidate resource set(s) belongs to the first candidate resource pool, any one of the Y1 candidate resource set(s) is one candidate resource set in the first candidate resource pool other than the Y2 candidate resource set(s); and the first signaling is used for indicating the target resource set. The disclosure avoids or reduces feedback collision.

    摘要: The present disclosure provides a method and a device in a UE and a base station used for wireless communication. A first node operates first information; and transmits a first radio signal in M1 out of M frequency sub-band(s). Herein, the first information is used for determining S candidate integers; K1 of K bit block group(s) is(are) used for generating the first radio signal, any of the K bit block group(s) comprises a positive integer number of code block(s); K is a candidate integer of the S1 candidate integer(s), M is used for determining the S1 candidate integer(s) out of the S candidate integers; the first node is a base station, the operating action is transmitting; or the first node is a UE, the operating action is receiving. The above method helps reduce the amount of data retransmitted due to LBT failure of partial frequency sub-bands.

    摘要: The present disclosure provides a method and device in UE and base station used for wireless communications. The UE receives first information, the first information being used for indicating a first precoding matrix; and transmits a first radio signal through a first antenna port group within a first time-domain resource in a first sub-band, or, drops wireless transmission through a first antenna port group within a first time-domain resource in a first sub-band. The first precoding matrix is used for determining K transmission parameter groups, K being a positive integer greater than 1; a first transmission parameter group is one of the K transmission parameter groups, and the first transmission parameter group is used for generating the first antenna port group, the first antenna port group comprising a positive integer number of antenna port(s). The method helps enhance the chance of uplink channel access, thereby improving the system capacity.

    摘要: The disclosure provides a method and a device in a node for wireless communication. A first node first receives a first radio signal, the first radio signal indicating a second index, then transmits a first signaling, and finally transmits a second radio signal; a first index and the second index are used for generating the first signaling and the second radio signal respectively; the first signaling is unrelated to the second index; and the first signaling includes configuration information for the second radio signal. Through establishing relationships between the first index and the first signaling and between the second index and the second radio signal respectively, the disclosure improves the efficiency of transmission of data and corresponding feedbacks between terminals in Internet of Things (IoT) and Vehicle-to-Everything (V2X) systems, thereby improving the spectrum efficiency and flexibility of systems.
