Claim of US Patent No. 9,167,586

1. A method of operating a Long Term Evolution (LTE) wireless communication network to communicate with User Equipment (UE),
the method comprising:
wirelessly exchanging first voice data using a resource block allocation;
receiving a Received Signal Strength Indication (RSSI) and a Signal to Interference-plus-Noise Ratio (SINR) for the UE;
determining if the RSSI for the UE is above a cell-edge proximity threshold;
if the RSSI for the UE is above the cell-edge proximity threshold, then determining if the SINR for the UE is above a resource
element allocation threshold;

if the SINR for the UE is determined to be above the resource element allocation threshold, then switching the UE from the
resource block allocation to a resource element allocation; and

in response to the switch to the resource element allocation for the UE, allocating individual resource elements to the UE
and wirelessly exchanging second voice data using the allocated individual resource elements.
