Abstract: This application provides a network device-based communication method, where channel resources are divided according to a specific rule. The method includes: determining, by a network device, at least two channels, where a spacing between center frequencies of two adjacent channels in the at least two channels is a positive integer multiple of a subcarrier spacing or a positive integer multiple of a resource block RB spacing; and communicating, by the network device, by using at least one of the at least two channels. Channel resource division is determined based on the spacing between center frequencies of two adjacent channels, implementing adaptation to an application scenario in which a bandwidth is flexible.

Abstract: This application discloses a beam training method, a communication device, a chip system, and a storage medium. The method includes: performing, by a transmit device, clear channel assessment on sectors corresponding to an antenna of the transmit device; and sending, by the transmit device in a sector whose result of clear channel assessment is idle, a training signal to a receive device, where the training signal is used to perform beamforming training on the antenna. With this solution, beamforming training efficiency can be improved and resource utilization can be increased.

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: This application discloses a communication method. The method includes: comparing, by a second transmit end device, a second bandwidth carrying at least one second service transmission and a first bandwidth, wherein the first bandwidth is used by a first transmit end device within a first specified time period on an unlicensed frequency band to complete first service transmission, the at least one second service transmission started in a remaining time period of the first specified time period after the first service transmission is completed; performing channel listening on the second bandwidth based on a result of the comparison; and performing, by the second transmit end device, the second service transmission on the second bandwidth if the second bandwidth is found to be in an idle state. In addition, a corresponding transmit end device is disclosed. This application discloses a channel listening mechanism applicable to a flexible-bandwidth scenario.

Abstract: A HARQ information transmission method and apparatus, to resolve a problem that HARQ information is not fed back in a timely manner. When a first device cannot successfully send first hybrid automatic repeat request (HARQ) information on a first time-frequency resource, or a second device cannot successfully receive the first HARQ information on the first time-frequency resource, the first device retransmits the first HARQ information on a second time-frequency resource for transmitting second HARQ information corresponding to second data. First data and the second data may be data with different priorities and/or in different groups. In this way, HARQ retransmission flexibility can be improved, and the first HARQ information is transmitted in a timelier manner, so that a data processing latency is reduced as much as possible.

Abstract: An apparatus and method for determining a control information indication are provided, wherein resource usage efficiency of physical broadcast channels can be improved. First information, which is sent by a network device, is received for indicating control information. The first information is used to indicate the number of symbols occupied by a control resource set (CORESET 0) in a time domain and a first offset of the CORESET 0 in a frequency domain. A time-frequency resource position of the CORESET 0 is determined based on the first information and a preset subcarrier spacing. Downlink control information at the time-frequency resource position of the CORESET 0 is received.

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.
