Abstract
Messages transmitted between a receiver and a transmitter are used to maximize a communication data rate. In particular, a multicarrier modulation system uses messages that are sent from the receiver to the transmitter to exchange one or more sets of optimized communication parameters. The transmitter then stores these communication parameters and when transmitting to that particular receiver, the transmitter utilizes the stored parameters in an effort to maximize the data rate to that receiver. Likewise, when the receiver receives packets from that particular transmitter, the receiver can utilize the stored communication parameters for reception.
Claims30
A multicarrier packet communication transceiver comprising:
- a receiver adapted to receive a packet including a header portion and a data portion, wherein the header portion indicates one or more communications parameters that were used for the data portion of the packet and includes a receiver station identifier, and the data portion was used for communication of a number of data bytes at a data rate, the receiver station identifier usable to determine whether the receiver is an intended recipient of the packet, the receiver entering a low power mode when it 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.
A method in a multicarrier packet communication transceiver comprising:
- receiving, by a receiver, a packet including a header portion and a data portion, wherein the header portion indicates one or more communications parameters that were used for the data portion of the packet and includes a receiver station identifier, and the data portion was used for communication of a number of data bytes at a data rate, the receiver station identifier usable to determine whether the 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.
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 transceiver comprising:
- receiving, by a receiver, a packet including a header portion and a data portion, wherein the header portion indicates one or more communications parameters that were used for the data portion of the packet and includes a receiver station identifier, and the data portion was used for communication of a number of data bytes at a data rate, the receiver station identifier usable to determine whether the 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.
