Abstract: A method and a device in nodes used for wireless communications are disclosed in the present disclosure. A first node receives a first signaling; the first signaling is used to indicate a first priority, a first parameter and a first radio resource block; the first parameter is used to indicate whether the first radio resource block is to be reserved for an initial transmission; and the first priority and the first parameter are jointly used to determine whether the first radio resource block can be occupied. The present disclosure improves the success rate of correct reception of retransmitted data, thereby ensuring the requests for delay in sidelink transmission.

Abstract: The present disclosure discloses a method and a device in a node for wireless communication. The first node transmits first information; receives second information; transmits a first bit-block set on a first time-frequency-resource block; transmits or drops transmission of a third bit-block set on a third time-frequency-resource block; and receives a second signal on a fourth time-frequency-resource block; the first information is used for indicating that the fourth time-frequency-resource block is associated with the third time-frequency-resource block; the second information indicates that the fourth time-frequency-resource block is associated with the first time-frequency-resource block; the second signal is used for indicating whether a target bit-block set is correctly received; when the first node transmits the third bit-block set on the third time-frequency-resource block, the target bit-block set is the third bit-block set, otherwise the target bit-block set is the first bit-block set.

Abstract: The present disclosure provides a method and a device in a node used for wireless communication. A first node receives a first information element, the first information element being used for indicating a first reference power value; and receives a second information set, the second information set comprising a second information element, the second information element being used for indicating a second limit power value; and transmits a first radio signal with a first power value; a target receiver of the first radio signal includes a transmitter of the first information element, the first power value is related to a smaller value between the first reference power value and the second limit power value. Taking into account restrictions resulted from interference when adjusting a transmitting power of a desired signal, the present disclosure can address interferences that may occur in V2X system in unicast or groupcast transmission.

Abstract: The present application discloses a method and device for positioning. A first node receives first configuration information; receives a first candidate signal on a first candidate time-domain resource block; and transmits a first positioning reference signal; the first configuration information is used to indicate a first time-domain resource group, the first time-domain resource group comprising at least one time-domain resource block; a measurement result of the first candidate signal is greater than a first threshold; whether the first candidate time-domain resource block belongs to the first time-domain resource group is used to determine whether a transmitter of the first candidate signal is selected as a synchronization reference for the first positioning reference signal. This application helps enhance the positioning accuracy by addressing the synchronization of multiple SL PRS.

Abstract: The present disclosure method and device in node used for wireless communication. A first node receives first information, the first information being used for indicating a first time-unit format; determines second information; and determines a first resource pool; herein, a first time window comprises Q first-type time-domain-resource blocks, the Q being a positive integer greater than 1; a first symbol is one of the positive integer number of multicarrier symbol(s) comprised in any of the Q first-type time-domain-resource blocks; the first time-unit format is used for indicating whether the first symbol is a first-type symbol; the second information is used for indicating a positive integer number of first-type time-domain-resource block(s) out of a first time-domain-resource-block subset. A flexible slot format has been taken into account in the process of V2X resource pool configuration in the present disclosure, thus ensuring that the resource pool can effectively meet traffic requirements.

Abstract: A method and device in a node for wireless communications. A first node transmits a first signaling; transmits a first reference signal and a second signal through a first antenna port in a first time-frequency resource set; the first signaling is used to indicate a number of time-frequency resource(s) used for the first reference signal in the first time-frequency resource set; the first reference signal is used to demodulate the second signal; the first antenna port conforms to a first Quasi Co-Located (QCL) relation, and the first QCL relationship is one of Q candidate QCL relationships; the number of time-frequency resource(s) used for the first reference signal in the first time-frequency resource set is used to indicate the first QCL relationship out of the Q candidate QCL relationships, Q being a positive integer greater than 1. The application effectively solves the signaling overhead problem of transmission configuration indication.

Abstract: The present disclosure provides a method and a device in a node for wireless communications. A first node receives a first signaling; transmits a second signaling; and transmits a first signal in a second time-frequency resource set; the second time-frequency resource set belongs to a target resource sub-pool; the first signaling is used to determine a first identifier, a first priority and a reference time-frequency resource set; a first time-frequency resource set is related to the reference time-frequency resource set; the second signaling is used to indicate a second identifier, a second priority and the second time-frequency resource set; a relationship between a first transmission node identified by the first identifier and a second transmission node identified by the second identifier. The present disclosure offers an effective way of addressing the resource wastes and transmission delay resulting from PSFCH conflicts in the NR V2X system.
