CHANNEL SELECTION RULES FOR SUB-1-GHz BASIC SERVICE SETS

摘要

Certain aspects of the present disclosure provide methods and apparatus for the coexistence of 1 MHz and 2 MHz operation modes within a wireless communication system in accordance with IEEE 802.11ah, for example. One example method generally includes scanning a plurality of channel pairs, wherein each of the channel pairs comprises a first channel having a first channel designation and a second channel having a second channel designation; determining, based on the scan, a set of open channels from the plurality of channel pairs in which no other apparatus is operating; selecting a primary channel based on the determination; and transmitting using the selected primary channel. The selection of the primary channel involves channel selection rules disclosed herein.

主权项

1. A first apparatus for wireless communications, comprising:
a transmitter configured to transmit a first transmission using a first channel of a channel pair, the channel pair comprising the first channel and a second channel; and a receiver configured to receive a second transmission from a second apparatus, wherein the second transmission is received on both the first and second channels of the channel pair, wherein one of the first and second channels is designated as a primary channel for the second apparatus, and wherein the receiver is configured to receive the second transmission regardless whether the first channel or the second channel is designated as the primary channel.
