5. The system of claim 1, wherein the number of data bytes communicated in the data portion of the packet is greater than the legacy number of data bytes indicated in the legacy header portion of the packet.
6. The system of claim 1, wherein the data rate used in the data portion of the packet is greater than the legacy data rate indicated in the legacy header portion of the packet.
7. The system of claim 1, wherein the transceiver is or includes one or more of: a wireless transceiver, a wireless 802.11 station, a wireless 802.11 access point, a wired transceiver, a DSL modem, an ADSL modem, an xDSL modem, a VDSL modem, a multicarrier transceiver, a general purpose computer, a special purpose computer, a programmed microprocessor, a microcontroller and peripheral integrated circuit element(s), an ASIC, a digital signal processor, a hard-wired electronic or logic circuit and a programmable logic device.
8. The system of claim 1, wherein power is saved by not decoding at least a portion of the packet.
9. A method in a multicarrier packet communication system comprising:
transmitting, by a transmitter, a packet including a header portion and a data portion, wherein the header portion indicates one or more communications parameters used for transmission of the data portion of the packet and includes a receiver station identifier, and the data portion is used for communication of a number of data bytes at a data rate, the receiver station identifier usable to determine whether a receiver is an intended recipient of the packet; and
entering a low power mode when the receiver is not an intended recipient of the packet, wherein the header portion also includes a legacy header portion containing a Rate field indicating a legacy data rate value and a Length field indicating a legacy number of data bytes, a number of data bytes communicated in the data portion of the packet is different than the legacy number of data bytes indicated in the legacy header portion of the packet, and a data rate used in the data portion of the packet is different than the legacy data rate value indicated in the legacy header portion of the packet, wherein the Rate field and Length field are used to defer transmission for a period of time and wherein station identifier bits in an extended header field are decoded to determine if the receiver is the intended recipient of the packet.
10. The method of claim 9, wherein the receiver decodes a portion of the packet when the receiver determines it is not the intended recipient of the packet.
11. The method of claim 9, wherein the Rate field and Length field are used to determine a duration of time.
12. The method of claim 9, wherein the Rate field and Length field are used to set a Network Allocation Vector (NAV).
13. The method of claim 9, wherein the number of data bytes communicated in the data portion of the packet is greater than the legacy number of data bytes indicated in the legacy header portion of the packet.
14. The method of claim 9, wherein the data rate used in the data portion of the packet is greater than the legacy data rate indicated in the legacy header portion of the packet.

17. A non-transitory computer readable information storage medium having stored thereon instructions, that when executed by a processor, cause to be performed a method in a multicarrier packet communication system comprising:
transmitting, by a transceiver, a packet including a header portion and a data portion, wherein the header portion indicates one or more communications parameters used for transmission of the data portion of the packet and includes a receiver station identifier, and the data portion used for communication of a number of data bytes at a data rate, the receiver station identifier usable to determine whether a receiver is an intended recipient of the packet; and
18. The medium of claim 17, wherein the receiver decodes a portion of the packet when the receiver determines it is not the intended recipient of the packet.
19. The medium of claim 17, wherein the Rate field and Length field are used to determine a duration of time.
