Abstract: The technology of this application relates to a method for transmitting uplink control information. The method includes a network device sending first signaling in a first cell to a terminal device. The terminal device may send uplink control information in a second cell based on the first signaling. The uplink control information may be uplink control information corresponding to the first cell and/or uplink control information corresponding to a third cell. The third cell is a cell other than the first cell and the second cell. According to the method provided in this application, a cell for sending the uplink control information may be dynamically configured for the terminal device, and can improve communication efficiency.

Abstract: In a RA-RNTI processing method, after an LBT success, NR-U UE randomly selects a preamble preamble, and selects an available random access time-frequency resource RO; sends the preamble on the selected RO; and generates a RA-RNTI based on the RO. Specifically, a first indicator sent by a network apparatus may be received, where the first indicator is used to indicate time information or position information of a RAR; and the NR-U UE detects a PDCCH only within a time window (the RAR) indicated by the first indicator, where the PDCCH is scrambled by the gNB by using a same RA-RNTI.

Abstract: A signal transmission method and apparatus are described. A network device indicates an uplink transmission resource to a terminal by using first indication information, and the terminal transmits a PUCCH and a first signal on the uplink transmission resource indicated by the first indication information. The uplink transmission resource is within an unlicensed frequency band, and the first signal includes one or more of a PUSCH, an SRS, and a PRACH. Thus, if resources required for PUCCH transmission are fewer than resources included in one interlace in the unlicensed frequency band, a remaining resource in the interlace may be used to transmit the first signal.

Abstract: A tracking reference signal (TRS) burst transmission method and apparatus wherein a transmit end determines to send a first TRS burst in the first slot in a maximum channel occupancy time (MCOT), that is, the TRS burst is sent at a start moment of the MCOT, so that a receive end can obtain precise time-frequency synchronization as soon as possible. In addition, when a length of a first MCOT is greater than Y slots, in addition to sending the first TRS burst in the first slot in the MCOT, it is further determined to send a second TRS burst in a slot that is in the first MCOT and whose distance to a start slot of a previous TRS burst is Y slots, to improve effectiveness of the time-frequency synchronization and further improve the reliability of receiving the data at the receive end.
