Problems solved by technology

[0004] In the existing standard, there is no definition for 802.11ax PPDU working in the channel bandwidth below 20MHz. If the existing PPDU format is used for data transmission, this is contrary to the vision of 802.11ax. Therefore, , it is necessary to provide a technology that can work in a channel with a bandwidth less than 20MHz, and can improve the spectrum utilization in wireless communication

Abstract

The embodiment of the invention provides a method and equipment for data transmission in a wireless local area network. The method comprises the steps of generating a PLCP protocol data unit (PPDU), wherein the bandwidth of a channel bearing the PPDU is less than 20MHZ, the PPDU comprises M high-efficiency short training fields (HE-STFs) and a data field and does not comprises a legacy-short training field (L-STF) with a backward compatibility function, a legacy-long training field with the backward compatibility function or a legacy-signal (L-SIG) with the backward compatibility function; and sending the PPDU. The PPDU in the embodiment of the invention does not comprises the L-STF with the backward compatibility function, the L-LTF with the backward compatibility function or the L-SIG with the backward compatibility function, and the bit of the PPDU is reduced, thereby saving spectrum resources used for transmitting the PPDU, and improving the spectrum utilization ratio.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and equipment for data transmission in a wireless local area network. Background technique [0002] In May 2013, 802.11 established the next-generation Wireless Fidelity (Wireless Fidelity, Wi-Fi) technology research group High Efficiency Wireless Local Area Network (High Efficiency WLAN, HEW). Throughput: improve the effective use of spectrum and improve user experience (Quality of Experience, QoE). The existing Wi-Fi technology only improves the quality of service and adapts to a denser communication environment than the existing Wi-Fi technology. [0003] In order to improve the efficiency of spectrum utilization, the 802.11ax (HEW) task group will use Orthogonal Frequency Division Multiple Access (OFDMA) technology for data transmission, and stipulate the physical The layer protocol data unit frame, that is, the frame format of the physical layer convergence procedure (phy...
