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: Present application provides a method and device in a node for wireless communications. A first node receives a first signaling; executes channel sensing in a first resource pool; and transmits a third signaling; any first-type time-frequency resource block in the first resource pool occupies L frequency-domain resource unit(s) in frequency domain; the first signaling indicates L and a first priority; a first time-frequency resource block has an overlapping with time-frequency resources occupied by a first reference signal; the first priority and the second priority are used together to determine a first threshold; a measurement performed on the first reference signal and the first threshold are used together to determine whether a second time-frequency resource block belongs to a first candidate resource pool, and the second time-frequency resource block is associated with the first time-frequency resource block. The present application effectively implements inter-user coordination, which avoids continuous interference between users.

Abstract: The present disclosure provides a method and a device in a node used for wireless communication. A first node receives a first signal to determine a first channel quality; determines a first speed; and determines whether a first resource pool comprises a first time-frequency resource block; selects a target time-frequency resource block from the first resource pool; and transmits a second signal in the target time-frequency resource block; herein, the first speed is a speed of mobility of the first node; the first resource pool comprises multiple time-frequency resource blocks, whether the first resource pool comprises the first time-frequency resource block is dependent on the first speed. The present disclosure takes into account the speed of mobility of a user in resources sensing, thus ensuring that the channel quality which autonomously selects resources meets the current transmission requirements.

Abstract: The present application discloses a method and a device in a node for wireless communications. A first node receives a first signaling group, the first signaling group being used to indicate a first signature sequence group and a second signature sequence group; transmits a first signature sequence in a first time interval; and transmits a second characteristic sequence in a second time interval; whether the first signature sequence belongs to the first signature sequence group or the second signature sequence group is used for selecting the second signature sequence; any signature sequence in the first signature sequence group is associated with a shared channel resource unit in a first period. The present application avoids the situation where the first node persistently selects random access preambles without being associated with a shared channel resource unit, thus ensuring that the requirement on access delay for UE is satisfied.

Abstract: The present disclosure provides a method and device in nodes used for wireless communication. A first node receives a first signaling; transmits a second signaling, drops transmitting a first signal on a first radio resource block; or, drops transmitting a second signaling, transmits a first signal on a first radio resource block; the first signaling is used for a request for transmitting the first signal on the first radio resource block; and the first signaling is used to indicate a first radio resource block. Since a working status of the first node is timely informed, the present disclosure effectively solves the communication problems between peer nodes in the distributed system, thus reducing unnecessary signaling overhead and resource waste.
