用于高效能ＷＩ－ＦＩ环境的经缩短之训练栏位前置码结构;SHORTENED TRAINING FIELD PREAMBLE STRUCTURE FOR HIGH EFFICIENCY WI-FI ENVIRONMENT

摘要

本文揭示大致上系有关于用于高效能Wi-Fi环境的经缩短之训练栏位前置码结构。于一个实施例中，本文揭示系有关于一通讯系统具有一发射器发射由固定式及行动接收器所接收的一主机-同步封包。该主机-同步封包含有用于在一HEW环境中通讯之资讯。当接收时，各个接收器解码该主机-同步封包以(i)估计一频率偏位及/或一自动增益控制(AGC)设定值；(ii)设定与该频率偏位符合一致的一发射频率；及/或(iii)决定与该AGC符合一致的一新发射功率；(iv)调谐至一新频率偏位及增益控制设定值以接收来自该发射器之接续封包。; (ii) select a transmission frequency consistent with the frequency offset; and/or (iii) determine a new transmission power consistent with the AGC; (iv) tune to a new frequency offset and gain control setting to receive subsequent packets from the transmitter.
