Abstract: The present application discloses a method and device in a node for wireless communications. A first node receives a reference signal in a first reference signal resource sub-pool; determines a first function according to the receiving behavior in the first reference signal resource sub-pool; transmits a first information block, the first information block being used to determine the first function; receives a second information block, the second information block being used to determine whether a target reference signal resource is associated with the first function; and transmits a third information block, the third information block indicating a first compressed CSI, the first compressed CSI being an input to the first function for generating a first CSI. The method above can configure relations between reference signals and AI algorithms/parameters flexibly to choose an optimal AI algorithm/parameter for compressing/decompressing CSI based on a reference signal, thus optimizing the CSI feedback performance.

Abstract: The disclosure provides a method and a device in a node for wireless communication. A first node receives a first signal and a second signal, and the first node transmits a first information block and a second information block in a first time window. The first information block and the second information block are used for determining whether the first signal and the second signal are correctly received respectively; transmit power values of physical layer channels carrying the first information block and the second information block are both a first power value. Through the design in the disclosure, a transmit power of a feedback channel on a sidelink is associated with a priority; and when multiple feedback channels are transmitted in one same time window, a proper transmit power can be determined to optimize performances of the feedback channels on the sidelink.

Abstract: A method and a device in a node for wireless communications. A first node monitors or drops monitoring a first signal in a first resource block; and transmits a second signal in a second resource block. The second resource block corresponds to a first index; the first resource block is reserved for a HARQ-ACK for a bit block set transmitted in a third resource block; when a first condition set is fulfilled, a spatial relation of the second signal is unrelated to the first index; when the first condition set is unfulfilled, the first index is used for determining the spatial relation of the second signal; the first condition set relates to whether the first signal is conveyed in the first resource block. The method above provides an easy implementation of beamforming in a V2X system, which optimizes gains of beamforming and also prevents complicated signaling interaction.

Abstract: The present application discloses a method and a device in a node for wireless communications. A first node receives a first reference signal group to determine a first-type received quality group; maintains a second counter according to the first-type received quality group; and transmits a first signal. The first signal indicates a first reference signal; when a first counter is no larger than a first threshold, the first reference signal belongs to a first reference signal subset; when the first counter is larger than the first threshold, the first reference signal belongs to a second reference signal subset; a reference signal in the second reference signal subset does not belong to the first reference signal subset; as a response to a first condition set being satisfied, the first signal is triggered. The method above achieves rapid cross-cell beam switch, thus guaranteeing the service quality and avoiding ping-pong effect.

Abstract: Present disclosure discloses method and device in a node used for wireless communication. A first node receives a first information block and a first signaling; and operates a first signal. The first information block is used for determining M first-type indexes out of N first-type indexes; the M first-type indexes are used for determining M1 information elements out of N1 information elements, and for determining M2 information elements out of N2 information elements; the first signaling comprises scheduling information of the first signal, and a first information element is used for determining Rx/Tx parameters of the first signal; when the operating is receiving, the first signaling indicates the first information element out of the M1 information elements; when the operating is transmitting, the first signaling indicates the first information element out of the M2 information elements. The above method streamlines beam management and improves the performance of uplink data transmission.

Abstract: The present disclosure provides a method and a device in a User Equipment (UE) and a base station used for wireless communications. The UE receives first information; determines first sub-information out of the M piece(s) of sub-information; receives a first radio signal in a first time-frequency resource set; the first information comprises the M piece(s) of sub-information, each of the M piece(s) of sub-information indicates a reference signal group, and a reference signal group comprises at least one reference signal. The first sub-information indicates a first reference signal group. A reference signal in a reference signal group indicated by at least one of the M piece(s) of sub-information is transmitted by a first serving cell, and the first serving cell is not added by the UE. The above method not only obtains performance advancement brought by serving cell handover, but also avoid time delay and service interrupt.

Abstract: The present disclosure provides a method and a device in a node for wireless communications. A first node receives a first signaling and a first signal in a first time-frequency resource pool; the first signaling comprises scheduling information of the first signal; the first signal carries a first bit block, the first bit block comprising a positive integer number of binary bits; a first value is used for determining a number of binary bits comprised in the first bit block, and the first value is related to the first time-frequency resource pool. The above method helps prevent both sides of communications from different interpretations of Transport Block Size in V2X communications, thus ensuring communication quality and avoiding extra signaling overhead.

Abstract: The present disclosure provides a method and a device in a node for wireless communications. A first node determines a first resource set and a first resource set group from M resource sets; and monitors a first-type channel in the first resource set group in a first time window. Any two of the M resource sets are overlapping in time domain, and the first resource set group comprises the first resource set; any of the M resource sets is linked to one or two spatial states; a second resource set is any of the M resource sets different from the first resource set; whether a first condition is fulfilled is used to determine whether the second resource set belongs to the first resource set group. The above method avoids performance loss resulting from the UE's unnecessary abandonment of monitoring over some PDCCH candidates.
