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 present disclosure discloses a method and device used in wireless communication node. A first node first receives K1 first-type radio signals, and then transmits a first signaling, receives a second signaling and transmits a first radio signal in sequence; the first signaling is used to indicate K2 first-type radio signal(s) of the K1 first-type radio signals, while the second signaling is used to indicate K3 first-type radio signal(s) of the K1 first-type radio signals; the K3 first-type radio signal(s) is(are) respectively used to determine K3 pathloss(es). By designing a mechanism of interaction between a terminal and a base station, and the channel quality of sidelink detected by the terminal to determine a transmitting power of sidelink, the present disclosure manages to reduce interference to a cellular network while ensuring sidelink performance, thus improving the system's overall performance.

摘要： The present disclosure discloses a method and a device in a User Equipment (UE) and a base station for wireless communication. The UE receives a first signaling, the first signaling being used to determine a first time-frequency resource; receives a second signaling, the second signaling being used to determine a second time-frequency resource; and transmits a first bit block in the first time-frequency resource, or, transmits a first bit block in the second time-frequency resource. Time domain resource occupied by the first time-frequency resource and time domain resource occupied by the second time-frequency resource are non-orthogonal; the first signaling carries a first identifier or a second identifier; whether the first signaling carries the first identifier or the second identifier is used to determine whether the first bit block is transmitted in the first time-frequency resource or transmitted in the second time-frequency resource.
