MULTI-USER AGGREGATION OVER FREQUENCY

摘要

Embodiments describe mechanisms for an Access Point (AP) to aggregate multiple devices (e.g., stations (STA)) across frequency during a single time period. STAs will be considered for frequency aggregation only if they have a measured SNR at the AP below a threshold. Methods are described that select STAs for aggregation based on associated SNR and other criteria and then assign frequency slots to the selected STAs. Selection for aggregation and assignment to frequency slots can also be balanced across time, so that different STAs are selected for aggregation over time. Mechanisms are also described that increase the opportunities for frequency aggregation.

1. An access point comprising hardware processing circuitry configured to:
receive a message from a station; evaluate a signal measurement for the message; compare the signal measurement to a signal threshold, above which aggregation will not be considered; responsive to the signal measurement being above the threshold, send a first message to the station clearing the station to transmit using a full bandwidth; and responsive to the signal measurement being equal to or less than the threshold, send a second message to a plurality of stations to aggregate at least one additional station with the station, the message clearing the aggregated stations to transmit during the same time period, each on a different frequency slot occupying a portion of the full bandwidth.
