Problems solved by technology

In order to follow the design in 802.11ad, the existing EDMG Header design scheme divides the stuffing bits in the EDMG Header sequence into multiple 64-bit sequences, so as to use the Header design in 802.11ad for frame transmission, but this method is based on Each 64-bit unit is coded, modulated and sent, and the transmission performance is limited, especially under long-distance transmission conditions, it cannot meet the transmission performance requirements

Embodiment Construction

[0067] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0068] figure 1 It is a schematic diagram of the scene of the communication system to which the embodiment of the present invention can be applied. figure 1 The communication system includes one AP and three STAs. E.g, figure 1 STA1, STA2, and STA3 in . The AP can communicate with STA1, STA2 and STA3. In this system, the AP can schedule multiple STAs to perform signaling transmission and demodulation. It should be noted that the number of STAs is not ...

Abstract

Embodiments of the invention provide a frame transmission method and device. The method comprises the steps of performing filling operation and 1 / 2LDPC coding on an acquired EDMG Header sequence; constructing a first sequence and a second sequence according to a coding sequence obtained through coding, wherein each of the first sequence and the second sequence comprises all bits in the EDMG Headersequence, and comprises parity check coding bits of a part of or all coding sequences, and the first sequence and the second sequence are identical in length; modulating the first sequence and the second sequence, and inserting a guard interval between two modulated sequences so as to obtain a frame, and transmitting the frame. Through adoption of the frame transmission method and device, the frame transmission performance is improved.

Description

technical field [0001] The present invention relates to the field of communications, and more particularly, to methods and devices for transmitting frames. Background technique [0002] Standardization of wireless local area networks (Wireless Local Area Networks, WLAN) by the 802.11 series of standards greatly reduces the cost of the WLAN technology. Wireless Fidelity (Wireless Fidelity, Wi-Fi) is a brand of wireless network communication technology, held by the Wi-Fi Alliance, the purpose is to improve the interoperability between wireless network products based on the 802.11 standard, using the 802.11 series protocol A wireless local area network can be called a Wi-Fi network. [0003] At present, the 802.11 standard has undergone various versions such as 802.11a, 802.11b, 802.11g, 802.11n, and 802.11ac, and its technology has become more and more mature. 802.11ad is a branch of the Institute of Electrical and Electronics Engineers (IEEE) 802.11 (or WLAN, wireless local...
