Abstract:
1. A packet communication method in a multicarrier communications environment 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 the same number of data bits on a plurality of subcarriers, used for transmitting or receiving the first packet; receiving or transmitting a second packet, wherein the second packet includes information indicating a second allocation of data bits to subcarriers to be used for transmitting or receiving a third packet, wherein the second allocation is different than the first allocation; and transmitting or receiving the third packet that includes a header portion and a data portion, wherein: the header portion of the third packet includes information indicating the second allocation of data bits to subcarriers for the data portion of the third packet, and the second 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.
