Abstract
A system and method for partial bandwidth communication. The system includes a device that has a transceiver configured to connect to a network, a memory storing an executable program and a processor. The program causes the processor to perform operations including receiving data to be transmitted to second device, determining if the data uses less than a predetermined bandwidth used as a unit for a carrier aggregation, determining a plurality of sub-bands in the predetermined bandwidth, each sub-band including at least one pilot and a plurality of frequency tones, receiving network information from the second device, the network information indicating a preferred sub-band of the sub-bands, assigning one of the sub-bands to the second device based upon the network information, generating a packet including an indication, the indication indicating the assigned sub-band; transmitting the packet to the second device and transmitting the data in the assigned sub-band.
