Patent ID: 7924841

Claim:
A packet communication method for multicarrier communications comprising: transmitting or receiving, by a transceiver, a first packet that includes a header portion and a data portion, wherein: the header portion includes information indicating a first allocation of data bits to subcarriers for the data portion of the first packet, and the first allocation of data bits to subcarriers allocates more data bits to at least one subcarrier, used for transmitting or receiving the first packet, than to at least one other subcarrier, used for transmitting or receiving the first packet; transmitting or receiving a second packet, wherein the second packet includes information indicating a second modified allocation of data bits to subcarriers to be used for transmitting or receiving a third packet, wherein the second modified allocation of data bits is different than the first allocation of data bits; and transmitting or receiving the third packet which includes a header portion and a data portion, wherein: the header portion of the third packet includes information indicating the second modified allocation of data bits to subcarriers for the data portion of the third packet, and the second modified allocation of data bits to subcarriers allocates more data bits to at least one subcarrier, used for transmitting or receiving the third packet, than to at least one other subcarrier, used for transmitting or receiving the third packet.
