Abstract

Embodiments of a system and methods for distributed adaptive resource allocation to enhance cell edge throughput are generally described herein. Other embodiments may be described and claimed.

Claims

1. A device, comprising a wireless communications unit configured to:

determine that the device is a cell edge user and to transmit a first signal to a serving station to notify the serving station that a status of the device is a cell edge user; and

receive a second signal from the serving station allocating resources to the device, wherein the resources are allocated to the device based on the cell edge user status.

2. The device of claim 1, wherein the device is further configured to determine a preferred interference mitigation technique to provide a highest transmission throughput for the device.

3. The device of claim 2, wherein the device is further configured to determine interference mitigation techniques available to the device and to calculate a channel quality indicator (CQI) for each interference mitigation technique available to the device.

4. The device of claim 3, wherein the wireless communication unit is configured to transmit a signal to indicate a preferred interference mitigation technique if the highest transmission throughput is greater than a previous transmission throughput.

5. The device of claim 3, wherein the wireless communication unit is configured to transmit a signal to indicate that no interference mitigation technique will be applied by the device if the highest transmission throughput is provided without enabling any interference mitigation technique.

6. The device of claim 1, wherein the device is selected from the group consisting of a platform, user equipment (UE), subscriber station (SS), station (STA), mobile station (MS), advanced mobile station (AMS), high throughput (HT) station (STA), and a very HT STA (VHT STA).
