Abstract

See full text

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.
