Abstract: The disclosure provides a method and a device in a User Equipment (UE) and a base station for wireless communication. A first node generates a first bit block, performs channel coding and then transmits a first radio signal. The first bit block comprising all bits in a second bit block and all bits in a third bit block is used for an input of the channel coding, and an output of the channel coding is used for generating the first radio signal. A Cyclic Redundancy Check (CRC) bit block of a fourth bit block is used for generating the third bit block. The fourth bit block comprises all bits in the second bit block and all bits in a fifth bit block, the bits in the fifth bit block are of fixed values, and the fifth bit block is composed of K bits, the K being a positive integer.

Abstract: 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.

Abstract: The present disclosure provides a method and device in a node for wireless communications. A first node transmits a first signal, and the first signal is used for random access; in response to transmitting the first signal, monitors a first-type channel in a first resource set to detect a first-type signaling; monitors the first-type channel in a second resource set to detect a second-type signaling; receives a target signaling, the target signaling is used to determine a target time; and when the target signaling is a third-type signaling, in response to receiving the target signaling, stops monitoring the first-type channel in the first resource set after the target time; when the target signaling is a fourth-type signaling, in response to receiving the target signaling. The above method can quickly recover a beam for unicast service and a beam for PTM/multicast groupcast service after beam failure.

Abstract: The present disclosure provides a method and a device in a node used for wireless communications. A first node receives a first reporting configuration and a first signaling; and transmits a first information block. The first signaling indicates a first transmission configuration state; the first information block comprises a reporting for the first reporting configuration; the first reporting configuration comprises N resource configurations; the N resource configurations respectively correspond to N first-type indexes; the first transmission configuration state corresponds to a first index; the first index is used to determine a first resource configuration; a measurement on reference signal resource(s) only in the first resource configuration among the N resource configurations is used to generate the first information block. The above method ensures that a TCI state of reference signals constantly matches with configuration information with the beams being dynamically updated.

Abstract: A first node receives N CSI configuration information; updates a CSI reporting in a first CSI reporting subset; transmits a first information block; the N CSI configuration information is respectively used to determine N CSI reportings, and the first CSI reporting subset is a subset of the N CSI reportings; the first information block comprises at least one CSI reporting of the N CSI reportings; any Type I CSI reporting in the N CSI reportings corresponds to a first-type integer, and any Type II CSI reporting in the N CSI reportings corresponds to a second-type integer, the N CSI reportings respectively correspond to N priorities, and the N priorities are used to determine a number of CSI reporting(s) comprised in the first CSI reporting subset. The above method configures different processing units for CSI reportings with different CSI computing power requirements, thus avoiding the waste of computing power.

Abstract: The present disclosure a method and a device in a UE and a base station used for wireless communications. A first node performs Q energy detection(s) on a first sub-band to obtain Q detection value(s); and determines based on the Q detection value(s) that a first radio signal is transmitted on the first sub-band at a first instant of time; performs P energy detection(s) on a second sub-band to obtain P detection value(s); and transmits or drops transmitting a second radio signal on the second sub-band at the first instant of time; each of the Q energy detection(s) is associated with a first antenna port group; when each of the P energy detection(s) is associated with the first antenna port group, the P is P1, otherwise the P is P2. The present disclosure is advantageous in ensuring fairness in the contention for spectrum occupancy in multicarrier-supporting Unlicensed Spectrum communications.

Abstract: The present disclosure discloses a method and a device for wireless communications in a UE and a base station. A first node transmits a first signal; and monitors a first-type signaling in a first resource block in a first time window. The first signal is used for determining a first reference signal; the first node assumes a QCL parameter identical to a target reference signal for monitoring the first-type signaling in the first resource block in the first time window; the target reference signal is either the first reference signal or a second reference signal; whether the first time window belongs to a first-type time window is used for determining the target reference signal between the first reference signal and the second reference signal. The method provided above raises the chance of a node being served and resource utilization ratio in Unlicensed Spectrum.
