SYSTEMS AND METHODS FOR IMPLEMENTING AN OFDMA LTF DESIGN FOR WIRELESS NETWORK COMMUNICATION

摘要

Systems, methods, and apparatuses are disclosed herein for aligning HE-LTFs corresponding to a plurality of users by determining a respective number of spatial streams corresponding to each user, determining a highest respective number of spatial streams of the spatial streams, and setting an alignment number of HE-LTF symbols to be equal to or larger than the highest respective number of spatial streams. For each respective user, a respective matrix of HE-LTF symbols corresponding to the respective number of spatial streams of the respective user is selected, and it is determined whether the respective matrix of HE-LTF symbols has fewer symbols than the alignment number. In response to determining that the respective matrix of HE-LTF symbols has fewer symbols than the alignment number, padding symbols may be added to the respective matrix to yield a number of HE-LTF symbols in the respective matrix that corresponds to the alignment number.

1. A method for aligning high efficiency long training fields (“HE-LTF”) for data corresponding to a plurality of users, the method comprising:
determining a respective number of spatial streams corresponding to each user of a plurality of users; determining a highest respective number of spatial streams of the spatial streams corresponding to the plurality of users; setting an alignment number of HE-LTF symbols to be equal to or larger than the highest respective number of spatial streams; for each respective user, selecting a respective matrix of HE-LTF symbols corresponding to the respective number of spatial streams of the respective user; determining whether the respective matrix of HE-LTF symbols has fewer symbols than the alignment number; and in response to determining that the respective matrix of HE-LTF symbols has fewer symbols than the alignment number, adding padding symbols to the respective matrix to yield a number of HE-LTF symbols in the respective matrix that corresponds to the alignment number.
