Abstract
This application provides a communication method and apparatus. The method may be applied to a WLAN system supporting 802.11 series protocols such as a next-generation Wi-Fi protocol of IEEE 802.11ax like 802.11be, Wi-Fi 7, or EHT, and a next-generation protocol of 802.11be like Wi-Fi 8, and may also be applied to a UWB-based wireless personal area network system, a sensing system, and the like. In the solutions of this application, a channel estimation sequence corresponding to a bandwidth greater than 320 MHz is designed, to support signal transmission in a large-bandwidth (for example, 640 MHz or 480 MHz) scenario.
Claims12
A transmit end, comprising a processor, wherein the processor is configured to execute a computer program or instructions stored in a memory, to enable the transmit end to perform a method as below:
- generating a physical layer protocol data unit (PPDU), wherein the PPDU comprises a first field, the first field is used to carry a first sequence, the first sequence is used by a receive end to perform channel estimation, the first sequence corresponds to a first bandwidth, and the first bandwidth is greater than 320 MHz;
- and
- sending the PPDU to the receive end.
A receive end, comprising a processor, wherein the processor is configured to execute a computer program or instructions stored in a memory, to enable the receive end to perform a method as below:
- receiving a physical layer protocol data unit (PPDU), wherein the PPDU comprises a first field, the first field carries a first sequence that passes through a wireless channel, the first sequence that passes through the wireless channel corresponds to a first bandwidth, and the first bandwidth is greater than 320 MHz;
- and
- performing channel estimation based on the first sequence that passes through the wireless channel and a preset first sequence.
