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 provides a method and a device in a communication node for wireless communications. The communication node in the present disclosure first receives first information, and then transmits a first radio signal; a length of a time interval between a start time for transmitting the first radio signal and a first reference time is equal to a sum of a first timing adjustment and a second timing adjustment, the first timing adjustment being one of X candidate timing adjustments, the X being a positive integer greater than 1; the second timing adjustment is used for determining a transmission timing of a radio signal transmitted before the first radio signal in time domain; a transmitter of the first radio signal determines the first timing adjustment out of the X candidate timing adjustments by itself. The present disclosure can improve uplink synchronization performance.

摘要： The present disclosure provides a method and a device in nodes for wireless communication. A first node receives first control information, the first control information being used for indicating a first radio resource group, and the first control information being used for indicating a first priority; chooses a target radio resource from a target resource pool; and transmits a first radio signal in the target radio resource; the first radio signal corresponds to a second priority; if the second priority is lower than the first priority, the target resource pool is orthogonal with the first radio resource group. The method adopted in the present disclosure allows part of reserved resources to be released temporarily to meet abrupt service requirements, so as to achieve timely transmission of aperiodic and emergent service data, and thereby realizing efficient utilization of radio resources.

摘要： The present disclosure discloses a method and device in UE and base station used for wireless communications. A UE transmits a first radio signal, the first radio signal indicating a first reference signal out of M reference signals; and monitors a first signaling in each of W time-frequency resource block(s). Herein, at least one reference signal of the M reference signals is transmitted by a first serving cell, and the first serving cell is not added by the UE; the UE assumes that a transmission antenna port of the first signaling is Quasi-Co-Located with a transmission antenna port of the first reference signal; W is a positive integer, and M is a positive integer greater than 1. Such method can be employed to avoid delay and service interruption brought about by cell handover.

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.
