摘要： Certain aspects of the present disclosure relate to techniques for improving a transmission throughput of communications based on IEEE 802.11af physical (PHY) layer in television white space (TVWS) spectrum. In one aspect, a transmission preamble with a Legacy Signal (L-SIG) field is constructed, wherein the L-SIG field comprises a code indicating duration of a cyclic prefix (CP) of a packet following the preamble. The transmissions can be performed using 5 MHz bandwidth of the TVWS spectrum.

摘要： Systems, methods, and devices for communicating and detecting training sequences are described herein. In one aspect, a method of wireless communication is provided. The method comprises receiving one or more short training field (STF) sequences comprising sixty-four values or less. The STF sequences comprise zero and non-zero values. The non-zero values are located at one or more indices of the STF that are separated by a multiple of at least four. The method further comprises determining a first correlation between the STF and the STF shifted by a first shift length. The method further comprises determining a second correlation between the STF and the STF shifted by a second shift length. The method further comprises determining a fast Fourier transform (FFT) size based on the first correlation and the second correlation. The method further comprises decoding one or more data symbols based at least in part on the determined FFT size.
