Abstract
Methods, systems, and devices are provided for dynamically adapting the bandwidth of flexible bandwidth carriers. Adapting the bandwidth of a flexible bandwidth carrier may be achieved through changing the scale factor of the flexible bandwidth signal. Information such as traffic patterns, interference measurements, etc., may be utilized to determine the adapted scaling factors. In macrocellular deployments, for example, dynamically adjusting the bandwidth of a flexible bandwidth system may be utilized in order to increase network capacity, mitigate interference caused to other carriers, avoid adjacent carrier interference, and/or save energy on the network. Traffic pattern and other information may also be utilized to dynamically adjust uplink and downlink bandwidths of a flexible bandwidth carrier, either jointly or independently.
