Abstract:
1. A method for altering a channel bandwidth in a wireless system, the method comprising: sending a report request message to a wireless device from an access node, the report request message comprising a request for an indicator of an ability of the wireless device to change the channel bandwidth from a first channel bandwidth to a second channel bandwidth, wherein information is transmitted between the wireless device and the access node over the channel bandwidth; receiving a report response message from the wireless device at the access node, wherein the report response message comprises a channel condition for the wireless device; determining a change in the channel condition for the wireless device at the access node based on the report response message; and sending a bandwidth alteration message from the access node to the wireless device directing the wireless device to adjust the channel bandwidth from the first channel bandwidth to the second channel bandwidth when a change in the channel condition for the wireless device is determined, wherein the second channel bandwidth comprises a different number of subcarriers than the first channel bandwidth and wherein the number of subcarriers of the second channel bandwidth is less than the number of subcarriers of the first channel bandwidth when the change in the channel condition for the wireless device is indicative of a channel condition deterioration.
