Description

无线局域网通信方法和设备 WLAN communication method and apparatus

技术领域 FIELD

[0001] 本发明涉及通信领域,尤其涉及无线局域网通信方法和设备。 [0001] The present invention relates to communication field, and particularly relates to methods and apparatus for wireless LAN communication.

背景技术 Background technique

[0002] 在2013年5月,802. 11成立了下一代无线保真(Wireless Fidelity,简称"Wi-Fi")技术的研究组高效无线局域网(High Efficiency WLAN,简称"HEW"),主要的研究点是提高比现有Wi-Fi技术更高的吞吐量;提高频谱的有效利用效率、提高用户体验(Quality of Experience,简称"QoE"),现有的Wi-Fi技术只是提高服务质量以及比现有的Wi-Fi技术适应更加密集的通信环境。 [0002] In May 2013, 802.11 establishment of the next generation of wireless fidelity (Wireless Fidelity, referred to as "Wi-Fi") technical study group efficient wireless local area network (High Efficiency WLAN, referred to as "HEW"), the main studies point is to improve the throughput higher than the current Wi-Fi technology; improve the efficient use of spectrum efficiency, improve the user experience (quality of experience, referred to as "QoE"), an existing Wi-Fi technology is only improving the quality of service and adapt to more intensive communication environment than existing Wi-Fi technology.

[0003] 为了提高频谱的利用效率,802. I lax (HEW)任务组将采用正交频分多址(Orthogonal Frequency Division Multiple Access,简称"0FDMA")技术进行数据的传输,并且规定了在20ΜΗΖ、40ΜΗζ、80ΜΗζ以及160MHz分别使用子载波的个数,在不同的信道带宽下,子载波(tone)的集合可以为26-tones、52-tones、106-tones、242_tones、 484-tones 及996-tones〇 [0003] In order to improve the utilization efficiency of the spectrum, 802. I lax (HEW) Task will use orthogonal frequency division multiple access (Orthogonal Frequency Division Multiple Access, referred to as "0FDMA") technology to transmit data, and specifies the 20ΜΗΖ , 40ΜΗζ, 80ΜΗζ 160MHz were used and the number of sub-carriers, at different channel bandwidth, the set of sub-carriers (Tone) may be 26-tones, 52-tones, 106-tones, 242_tones, 484-tones and 996- tones〇

[0004] 在现有的标准中,由于没有使用OFDM技术,即设备独占信道,所以只规定了在不同的信道带宽下子载波的个数(由某个设备独自使用),所以现有标准中的子载波分配机制不能满足802. Ilax中的同一信道带宽下将不同的子载波分配给不同的用户来提高区域内吞吐量的需求。 [0004] In the conventional standards, since no OFDM technology, i.e., the exclusive channel device, so only a different predetermined channel bandwidth lower sub-carrier number (by the use of a device alone), the existing standards subcarrier allocation scheme can not meet the same channel bandwidth 802. Ilax in the different sub-carriers assigned to different user needs to increase the region of throughput.
