Abstract:
1. A method of operating a wireless communication system that uses multiple frequency bands to control carrier aggregation, the method comprising: monitoring intermodulation distortion in orthogonal frequency division multiplexing frequencies in the multiple frequency bands; receiving a communication service request for a wireless communication device; if the communication service request is Voice over Long Term Evolution (VoLTE), scheduling the wireless communication device to use intra-band contiguous carrier aggregation; if the communication service request is not VoLTE, and the intermodulation distortion is below a distortion threshold, scheduling the wireless communication device to use intra-band non-contiguous carrier aggregation; and if the communication service request is not VoLTE, and the intermodulation distortion is above the distortion threshold, scheduling the wireless communication device to use inter-band non-contiguous carrier aggregation.
