Abstract

The invention discloses a data transmission method, and belongs to the technical field of communication. The data transmission method comprises the following steps of: generating a PPDU; transmittingthe PPDU to at least one receiving end, wherein the PPDU comprises a channel estimation domain CEF, and the CEF comprises a plurality of sub-sequences; for each sub-sequence in the plurality of sub-sequences, enabling a part of elements or all elements in the sub-sequence to be basic elements, and arranging the basic elements into a Gray sequence or a ZC sequence in the sub-sequences. The data transmission method is used for data transmission.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a data transmission method, device and system. Background technique [0002] The standards adopted by the wireless local area network (Wireless Local Area Networks, WLAN) are the 802.11 series standards of the Institute of Electrical and Electronics Engineers (IEEE). Among them, IEEE802.11ay is a WLAN standard capable of achieving a relatively high data transmission rate among the existing IEEE802.11 series standards, and the operating frequency band of IEEE802.11ay is 60 gigahertz (GigaHertz, GHz). [0003] IEEE802.11ay adopts Orthogonal frequency division multiplexing (OFDM) technology. In IEEE802.11ay, the sending end can send a physical protocol data unit (Protocol data unit, PPDU) to a receiving end in one spectrum resource, so as to realize data transmission. Among them, the PPDU is divided into multiple sequence fields according to different functi...
