摘要： This application relates to the wireless communications field, for example, is applicable to a wireless local area network supporting the 802.11be standard, and in particular, to a PPDU uplink bandwidth indication method and a related apparatus. The method includes: An AP generates and sends a trigger frame. The trigger frame carries first indication information, where the first indication information directly indicates or jointly indicates an EHT TB PPDU bandwidth or an uplink PPDU total transmission bandwidth. The trigger frame carries second indication information, where the second indication information indicates distribution of an HE TB PPDU and/or an EHT TB PPDU in the uplink PPDU total transmission bandwidth, or directly indicate whether an EHT station transmits an HE TB PPDU or an EHT TB PPDU.

摘要： This application provides a method and an apparatus for sensing measurement. In a technical solution of this application, a transmit end of data may send an indication frame to a receive end of the data, where the indication frame may indicate a spatial mapping matrix used by the transmit end of the data to send the data to the receive end of the data. In this way, the receive end of the data can eliminate impact of spatial mapping on channel state information based on the spatial mapping matrix, to obtain actual channel state information, thereby completing sensing, positioning, and the like on an ambient environment or a passive target by using the obtained actual channel state information.

摘要： This disclosure provides data sending and receiving methods and apparatuses. In an implementation, a device performs a non-replication operation on a frequency domain sequence on subcarriers of a first bandwidth, to obtain a frequency domain sequence on subcarriers of a second bandwidth in a transmission bandwidth, transforms the frequency domain sequence on the subcarriers of the first bandwidth and the frequency domain sequence on the subcarriers of the second bandwidth into a time domain, and performs radio frequency processing on time domain data and then sends the processed time domain data.
