Abstract: A method for sending a physical layer protocol data unit (PPDU) may be applied to some scenarios in which PPDU alignment is implemented. For example, in multi-link transmission of non-simultaneous transmit and receive, it is ensured that a time error of simultaneous ending of a plurality of PPDUs does not exceed 8 microseconds. In the method, a transmitter controls duration of one or more fields of a packet extension (PE) field, an Extremely High Throughput (EHT)-signal (SIG) field, and an EHT-long training field (LTF) field of the PPDU, and/or delays a sending time of the PPDU so that an error between an end time of the PPDU and a specific time (for example, a first time) is not greater than an error threshold, thereby implementing PPDU alignment.

Abstract: The present disclosure relates to inter-cell beam coordination scheduling methods and related devices. One example inter-cell beam coordination scheduling method includes receiving, by a first wireless access device serving a coordinated cell, a coordination scheduling request specific to an edge user terminal of a serving cell, where the coordination scheduling request carries an indication of a downlink narrow-transmission beam set DX1, and the downlink narrow-transmission beam set DX1 is a downlink narrow-transmission beam set that satisfies a principle of minimal interference and that is determined by the edge user terminal through beam training, and in a slot in which downlink scheduling is performed on the edge user terminal in the serving cell, preferably using, by the first wireless access device, a narrow-transmission beam in the downlink narrow-transmission beam set DX1 to schedule a camping user terminal of the coordinated cell in downlink.

Abstract: Embodiments of this application disclose a data transmission method and a communications apparatus. A method in an embodiment includes: sending, by a network device, first data to a terminal in a first subframe through a first channel, where the first channel is a channel occupied in a channel system by a service between the network device and the terminal; performing, by the network device, channel listening on a channel that is not occupied in the channel system by the service; and when there is a second channel in an idle state, sending, by the network device, second data of the service to the terminal in a second subframe through the first channel and the second channel, where the second subframe is after the first subframe. The service includes the first data and the second data, and a data frame of the service includes the first subframe and the second subframe.
