Patent ID: 8781008

Claim:
A method performed in a first electronic device, the method comprising: mapping, using a modulation constellation, each of C′ bit sequences to a respective one of C′ symbols, where C′ is a number greater than one; processing said C′ symbols to generate C′ inter-carrier correlated virtual subcarrier values; decimating said C′ virtual subcarrier values down to C physical subcarrier values, C being an number less than C′; transmitting said C physical subcarrier values on C orthogonal frequency division multiplexed (OFDM) subcarriers; receiving a first message from a second electronic device; in response to said first message, ceasing transmission of data on a particular one of said OFDM subcarriers; receiving a second message from said second electronic device; and in response to said second message, resuming transmission of data on said particular one of said OFDM subcarriers.
