Abstract
A network device for implementing high-rate greenfield transmission in a mixed mode frame structure. The network device is configured to transmit a mixed mode frame on two adjacent channels. The mixed mode frame comprises at least two backward compatible portions of a first frequency and a greenfield portion of a second frequency.
Claims20
A communication device, comprising:
- a backward compatible portion generator configured to:
- generate a backward compatible portion of a mixed mode frame, and
- generate a copy of the backward compatible portion;
- and
- a greenfield generator configured to:
- generate a greenfield portion of the mixed mode frame, and
- generate a dummy length and a dummy rate for the backward compatible portion and the copy of the backward compatible portion based on the greenfield portion.
4 more elements
A communication device, comprising:
- a backward compatible portion generator configured to:
- generate a backward compatible portion of a mixed mode frame based on a dummy length and a dummy rate, wherein the backward compatible portion contains timing information to instruct a receiver to ignore a transmission of a greenfield portion of the mixed mode frame, and
- generate a copy of the backward compatible portion;
- and
- a transmitter configured to:
- transmit the backward compatible portion over a first channel,
- transmit the copy of the backward compatible portion over a second channel, and
- transmit the greenfield portion.
5 more elements
A method, comprising:
- generating, using a first communication device, a backward compatible portion of a mixed mode frame based on a dummy length and a dummy rate, wherein the backward compatible portion contains timing information to instruct a second communication device to ignore a transmission of a greenfield portion of the mixed mode frame;
- transmitting, using the first communication device, the backward compatible portion over a first channel;
- transmitting, using the first communication device, the copy of the backward compatible portion over a second channel;
- and
- transmitting, using the first communication device, a greenfield portion of the mixed mode frame.
