METHODS AND APPARATUS FOR SCHEDULING A NARROWBAND RESPONSE TO WIDEBAND DATA IN A HIGH-EFFICIENCY WIRELESS LOCAL AREA NETWORK

摘要

Methods and apparatus are disclosed for scheduling a narrowband uplink transmission from a wireless station to a wireless access point in response to a station-specific wideband downlink transmission from the access point to the station. A station-specific downlink frame includes a station identifier associated with the station, and further includes resource allocation information associated with an uplink transmission channel over which the station is to transmit an uplink frame. The station-specific downlink frame is transmitted from the access point to the station over a downlink transmission channel having an associated downlink bandwidth. Based on the resource allocation information, the access point receives the uplink frame from the station over the uplink transmission channel. The uplink transmission channel has an associated uplink bandwidth that is narrower than the downlink bandwidth of the downlink transmission channel. In some disclosed examples, the uplink transmission channel is a sub-channel of the downlink transmission channel.

主权项

1. A wireless access point to schedule a narrowband response to wideband data, the wireless access point comprising:
a communication manager to identify (a) a station identifier associated with a wireless station and (b) resource allocation information associated with an uplink transmission channel over which the wireless station is to transmit an uplink frame; a transmitter to transmit a station-specific downlink frame from the wireless access point to the wireless station over a downlink transmission channel, the downlink transmission channel having an associated downlink bandwidth, the station-specific downlink frame including the station identifier and the resource allocation information; and a receiver to, based on the resource allocation information, receive the uplink frame at the wireless access point from the wireless station over the uplink transmission channel, the uplink transmission channel having an associated uplink bandwidth that is narrower than the downlink bandwidth of the downlink transmission channel, the uplink transmission channel being a sub-channel of the downlink transmission channel.
