Abstract: The present disclosure provides a method and a device in a node for wireless communications. A first node receives a first signaling and a first signal in a first time-frequency resource pool; the first signaling comprises scheduling information of the first signal; the first signal carries a first bit block, the first bit block comprising a positive integer number of binary bits; a first value is used for determining a number of binary bits comprised in the first bit block, and the first value is related to the first time-frequency resource pool. The above method helps prevent both sides of communications from different interpretations of Transport Block Size in V2X communications, thus ensuring communication quality and avoiding extra signaling overhead.

Abstract: A method and a device in a UE and a base station for wireless communications are provided in the present disclosure. A UE first receives a first signaling, the first signaling is used for indicating M first-type time window(s) in a first sub-band, and the M first-type time window(s) in the first sub-band is(are) reserved for a first-type reference signal, M being a positive integer; the UE then determines that it is only needed to receive the first-type reference signal in M1 first-type time window(s) of the M first-type time window(s) in a first sub-band, M1 being a positive integer no greater than the M. The present disclosure is advantageous in avoiding possible loss of performance in Unlicensed Spectrum resulting from belated determination of beam link failure due to the fact that the reference signal is not transmitted on time.

Abstract: The present disclosure provides a method and a device in a User Equipment (UE) and a base station used for wireless communication. The UE receives a first signaling in a first time window in a first subband; monitors a second signaling in a second time window in a second subband; if successfully receives the second signaling in the second time window in the second subband, transmits a first radio signal in a third time window in a third subband, otherwise drops transmission of the first radio signal in the third time window in the third subband. Herein, the first signaling comprises first-type scheduling information of the first radio signal. The above method allows the base station to flexibly control a transmission time of each uplink transmission on unlicensed spectrum according to specific conditions, such as the result of LBT or the direction of beamforming.

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: Disclosure discloses method and device in a node used for wireless communication. A first node receives a first information block and a first signaling; and operates a first signal. The first information block is used for determining M first-type indexes out of N first-type indexes; the M first-type indexes are used for determining M1 information elements out of N1 information elements, and for determining M2 information elements out of N2 information elements; the first signaling comprises scheduling information of the first signal, and a first information element is used for determining Rx/Tx parameters of the first signal; when the operating is receiving, the first signaling indicates the first information element out of the M1 information elements; when the operating is transmitting, the first signaling indicates the first information element out of the M2 information elements. The above method streamlines beam management and improves the performance of uplink data transmission.

A first node receives a first signaling and a second signaling; transmits K first radio signals in K time-frequency resource blocks respectively; the K time-frequency resource blocks are orthogonal in time domain; the first signaling indicates the K time-frequency resource blocks; only K1 first radio signals in the K first radio signals respectively comprise K1 second sub-signals, the K1 second sub-signals carry a second bit block, and the second signaling is used to determine the second bit block; a total number of REs occupied by the K1 second sub-signals is not greater than a first value, and a first coefficient is used to determine the first value. When control information is carried on a repeatedly transmitted physical layer data channel, the above method ensures the reliability of data and the control information.

Abstract: The present disclosure discloses a method and a device for wireless communications in a UE and a base station. A first node transmits a first signal; and monitors a first-type signaling in a first resource block in a first time window. The first signal is used for determining a first reference signal; the first node assumes a QCL parameter identical to a target reference signal for monitoring the first-type signaling in the first resource block in the first time window; the target reference signal is either the first reference signal or a second reference signal; whether the first time window belongs to a first-type time window is used for determining the target reference signal between the first reference signal and the second reference signal. The method provided above raises the chance of a node being served and resource utilization ratio in Unlicensed Spectrum.

Abstract: The present disclosure provides a method and device used in UE and a base station for wireless communications. The UE receives a first signaling; and operates a first radio signal. The first radio signal comprises K first-type sub-signals and K first-type reference signals; the first signaling is used for determining time-frequency resources occupied by the first radio signal; time-domain resources occupied by the K first-type sub-signals are non-orthogonal, and frequency-domain resources occupied by each two of the K first-type reference signals are mutually orthogonal; the K first-type reference signals are respectively used for channel estimation of the K first-type sub-signals, and a reference signal port of each of the K first-type reference signals is associated with a target reference signal port. The above method is advantageous in improving efficiency of PTRSs in multi-TRP/panel transmissions.
