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: This application provides a random access method, apparatus, and device, and a storage medium. The method includes: A terminal device scrambles first identification information of the terminal device by using an OCC, and sends a first message to a network device. After receiving the first message sent by the terminal device, the network device sends a second message to the terminal device based on the first message, where the second message includes identification information of one or more terminal devices that succeed in random access, so that the terminal device can determine, based on the identification information of the one or more terminal devices the one or more terminal devices include the first identification information of this terminal device, whether this terminal device succeeds or fails in random access.

Abstract: This application provides a system information transmission method, and a related device and system. The method includes: receiving, by a network device, a system information request sent by one or more terminals; transmitting, by the network device, system information SI, where SI transmitted for one terminal has a quasi-co-location QCL with a portion of downlink signal blocks, and the portion of downlink signal blocks are a subset of all downlink signal blocks transmitted by the network device; and sending, by the network device, first indication information, where the first indication information indicates a mapping between a downlink signal block and SI, and the downlink signal block has a QCL with the SI corresponding to the downlink signal block. The foregoing solution can reduce system overheads and improve resource utilization.

Abstract: Embodiments of this application provide a contention window management method applied to an unlicensed band. The method includes sending, by a sending device, one or more data packets to one or more receiving devices in one reference time unit or a plurality of reference time units, where the one or more data packets occupy a first bandwidth. The method further includes receiving, by the sending device from the one or more receiving devices, a hybrid automatic repeat request HARQ or HARQs for the one or more data packets. The sending device determines a contention window (CW) size of a second bandwidth with reference to the HARQ or HARQs. The CW update based on HARQ feedback improves communication efficiency.
