Abstract: Embodiments of this application provide a data transmission method, a network device, and a terminal device. The method includes: A network device sends resource indication information to a terminal device, so that the terminal device determines, based on the resource indication information, a resource allocated by the network device. The resource indication information is used to indicate location information of a resource in at least one BWP in a system bandwidth and bandwidth information of the at least one BWP. Further, the network device receives, on a resource corresponding to the resource indication information, uplink data sent by the terminal device. It can be learned that, in the embodiments, the network device may indicate a system bandwidth of any size and/or a resource in any BWP in the system bandwidth to the terminal device, so that the terminal device can perform data transmission on the indicated resource.

Abstract: Example hybrid automatic repeat request (HARQ) feedback methods and apparatus are described. One example method includes sending first indication information by a base station, where the first indication information is used to indicate a terminal to perform HARQ feedback. Second indication information is sent by the base station, where the second indication information includes second time information used to indicate the terminal to perform the HARQ feedback. The base station receives HARQ feedback information of the terminal. In one example method, the base station may send the first indication information within a first channel occupancy time (COT), and send the second indication information within a second COT.

Abstract: This application relates to the field of wireless communications technologies, and in particular, to a random access technology in an unlicensed frequency band. In a random access configuration method, a network device performs channel listening and obtains a channel occupancy time through contention. If a time-frequency resource used by a terminal device to transmit a random access preamble is configured in the channel occupancy time obtained by the network device through contention, the network device sends downlink control information to the terminal device, and the downlink control information is used to indicate configuration information for transmitting the random access preamble on the time-frequency resource. According to the solution provided in this application, the time-frequency resource for transmitting the random access preamble within the channel occupancy time may be dynamically configured, so as to flexibly use the channel occupancy time and improve communication efficiency in the unlicensed frequency band.

Abstract: Embodiments of the present invention provide a data transmission method and an apparatus. In the method, a communications node receives N spatial reuse parameters SRPs; the communications node determines, based on the received N SRPs, that the communications node can perform spatial reuse link transmission; and the communications node transmits data by using a spatial reuse link, and processes data transmission based on the spatial reuse link. Whether spatial reuse link transmission can be performed is determined based on the received SRPs, so as to reduce mutual interference between a primary link and the spatial reuse link during data transmission, and improve transmission quality.
