Sending information at a band edge within an orthogonal frequency-division multiplexing (ofdm) symbol

A method for utilizing bandwidth at an Orthogonal Frequency-Division Multiplexing (OFDM) symbol band edge, comprising:

• transmitting, from a transmitter located in one of an evolved NodeB (eNodeB) and a User Equipment (UE), data in an inbound span of sub-carriers of an Orthogonal Frequency-Division Multiplexing (OFDM) symbol at a first power range, the OFDM symbol comprising at least the inbound span of sub-carriers and at least one edge span of sub-carriers, wherein:
• the inbound span occupies a range of frequencies with a low frequency boundary and a high frequency boundary, and the at least one edge span occupies a range of frequencies that is at least one of adjacent to and below the low frequency boundary and adjacent to and above the high frequency boundary;
• and
• transmitting data in a portion of the at least one edge span at a second power range that is lower than the first power range of the inbound span.

A transmitter, located in one of an evolved NodeB (eNodeB) and a User Equipment (UE), operable to utilize an Orthogonal Frequency-Division Multiplexing (OFDM) band edge, comprising:

• reducing spectral leakage from an inbound region of an Orthogonal Frequency-Division Multiplexing (OFDM) into an Out-Of-Band (OOB) region not designated for the OFDM symbol;
• provisioning additional information to a band edge of the OFDM for transmission;
• and
• transmitting the OFDM symbol with the additional information in the band edge.
