Method, apparatus and system for uplink radio resource allocation in an LTE communication system

A LTE wireless communication system comprising:

• a user equipment (UE);
• and
• a base station including a subcarrier selection module, wherein:
• the subcarrier selection module is configured to select one or more frequency subcarriers within an LTE resource block for use by the UE, the selected one or more frequency subcarriers covering less than an entire frequency range of the LTE resource block, wherein the frequency range of the LTE resource block is 180 kHz, and wherein each of the one or more frequency subcarriers is selected from a contiguous range of 15 kHz subcarriers;
• the base station is configured to transmit a subcarrier selection message to the UE, the subcarrier selection message indicative of the selected one or more frequency subcarriers;
• the UE including a subcarrier selection message processing module implemented on a processor and configured to receive and process the subcarrier selection message;
• and
• the UE further includes a communication module implemented on a processor and configured to use the selected one or more frequency subcarriers for data communication from the UE to the base station,
• wherein one or more remaining frequency subcarriers within the LTE resource block are exclusively used by another UE to communicate to the base station in the uplink direction using OFDMA, in a manner that other UEs avoid simultaneously using the one or more remaining frequency subcarriers used by the another UE.
