Method of channel access in wireless local area network and apparatus for the same

摘要

A method for channel access in a wireless local area network is provided. The method includes: transmitting, a plurality of Request To Send (RTS) frames over a plurality of subchannels to a receiver, each RTS frame being transmitted over each of the plurality of subchannels; receiving at least one Clear To Send (CTS) frame over at least one subchannel among the plurality of subchannels from the receiver; each CTS frame being transmitted over each of the at least one subchannel, transmitting a data unit to the receiver. The data unit includes at least one data frame. The at least one data frame is transmitted over at least one selected subchannel among the at least one subchannel, each data frame being transmitted over each selected subchannel.

1. A method for channel access in a wireless local area network, comprising:
transmitting, by an apparatus, at least one Request To Send (RTS) frame over at least one first subchannel to a receiver, each of the at least one RTS frame being transmitted over a corresponding one of the at least one first subchannel; receiving, by the apparatus, at least one Clear To Send (CTS) frame as a response to the at least one RTS frame over at least one second subchannel from the receiver, each of the at least one CTS frame being received over a corresponding one of the at least one second subchannel, wherein the at least one second subchannel is identified by the at least one RTS frame, and wherein the at least one CTS frame is scrambled with a scrambling sequence initialized with a scrambler initialization value, the scrambler initialization value being determined based on a parameter of the at least one RTS frame.
