摘要： The disclosure provides a method and a device in a User Equipment (UE) and a base station for wireless communication. The UE receives a first signaling and a first radio signal, and transmits first information; only X1 bit(s) in a first bit block is(are) used for generating the first radio signal, the first bit block is obtained as an output of channel coding of a first code block; the first signaling is used for determining that the X1 bit(s) cannot be used for decoding of the first code block with combining when channel decoding for the X1 bit(s) fails. Through the design of the first information, the disclosure implements the update of a state of buffer occupation of the UE or a state of channel decoding, to facilitate a base station to adjust a transmission policy in real time, thereby improving overall performances.

摘要： The disclosure provides a method and device in User Equipment (UE) and base station. The UE receives first configuration information, and then receives a first radio signal and a second radio signal in first time domain resources and second time domain resources respectively. A first bit block is used for generating the first radio signal and the second radio signal. The first configuration information is applied to the first radio signal and the second radio signal. According to the disclosure, the first configuration information is used for configuring both the first radio signal and the second radio signal, and the first radio signal and the second radio signal are received on different time domain resources respectively; therefore, data corresponding to one same bit block can be transmitted through different modes, air interface resources can be fully utilized and the overall spectrum efficiency of the system can be improved.

摘要： The present disclosure discloses a method and a device in nodes used for wireless communications. A first node first receives a first radio signal and a second radio signal; and then determines that transmitting power of first control information in a first time window is a first power value and transmitting power of second control information in a second time window is a second power value; and transmits the first control information in the first time window with the first power value; the first power value is unrelated to the second power value, and the second power value is relevant to whether the first time window overlaps with the second time window. The present disclosure designs power allocation priorities of first control information and second control information to optimize both transmission performance and efficiency of a feedback channel in sidelink.

摘要： The disclosure provides a method and a device in a node for wireless communication. A first node first receives a first radio signal and a second radio signal, and transmits first information when a trigger condition is met. The first radio signal and the second radio signal are used for determining a channel quality of a first link and a channel quality of a second link respectively, the channel quality of the first link and the channel quality of the second link are used together for determining the trigger condition. The first information comprises a first parameter, and the first parameter is applied only to the first link of the first link and the second link. According to the above design, the triggering of PHR for a sidelink in V2X systems is associated with both the channel quality of the sidelink and the channel quality of a cellular link.
