METHOD AND APPARATUS FOR REDUCING INTERFERENCE BETWEEN WIRELESS DEVICES OPERATING AT DIFFERENT DATA RATES IN A WIRELESS NETWORK

摘要

An access point including a transceiver having first and second physical layers to communicate at first and second data rates, respectively. The transceiver receives a request from a first client station to reserve first or second sub-channel of a channel for transmitting data at the first or second data rate. In response to receiving the request from the first client station, the transceiver transmits a response to allow the first client station to transmit data and prevent a second client station from transmitting data while the first client station transmits data to the access point. In response to the first client station receiving the response, the first physical layer receives data from the first client station without interference from the second client station.

1. An access point comprising:
a transceiver including
a first physical layer configured to communicate at a first data rate via a first sub-channel and a second sub-channel of a channel; anda second physical layer configured to communicate at a second data rate via the first sub-channel or the second sub-channel of the channel, wherein the first data rate is greater than the second data rate, wherein the transceiver is configured to receive, from a first client station, a request to reserve (i) the first sub-channel, (ii) the second sub-channel, or (iii) the channel for transmitting data from the first client station to the access point at the first data rate or the second data rate, wherein in response to receiving the request from the first client station, the transceiver is configured to transmit a response to (i) allow the first client station to transmit data to the access point, and (ii) prevent a second client station from transmitting data to the access point while the first client station transmits data to the access point, and wherein in response to the first client station receiving the response, the first physical layer is configured to receive data from the first client station without interference from the second client station.
