Systems and methods for managing on-time of wireless receivers

A method of wireless communication, comprising:

• receiving, at a receiver, at least a portion of a data unit comprising one or more first training field sequences, the one or more first training field sequences encoded with a pseudo-random spreading code based on an addressee of a data unit;
• determining whether the pseudo-random spreading code is associated with the receiver;
• and
• refraining from decoding a portion of the data unit when the pseudo-random spreading code is not associated with the receiver.

A method of wireless communication, comprising:

• receiving, at a receiver, a data unit comprising one or more first training field sequences;
• determining whether the data unit comprises one or more differentially encoded symbols;
• and
• receiving one or more second training field sequences when the data unit does not comprise one or more differentially encoded symbols.

A wireless device comprising:

• a processor configured to:
• generate a data unit comprising one or more first training field sequences;
• and
• encode each of the first training field sequences with a pseudo-random spreading code based on an addressee of the data unit;
• and
• a transmitter configured to transmit the data unit over a wireless channel.

A wireless device comprising:

• a receiver configured to receive at least a portion of a data unit comprising one or more first training field sequences, the one or more first training field sequences encoded with a pseudo-random spreading code based on an addressee of a data unit;
• and
• a processor configured to:
• determine whether the pseudo-random spreading code is associated with the receiver;
• and
• refrain from decoding a portion of the data unit when the pseudo-random spreading code is not associated with the receiver.

A wireless device comprising:

• a receiver configured to receive data unit comprising one or more first training field sequences;
• and
• a processor configured to:
• determine whether the data unit comprises one or more differentially encoded symbols,
• wherein the receiver is further configured to receive one or more second training field sequences when the data unit does not comprise one or more differentially encoded symbols.

An apparatus for wireless communication comprising:

• processing means for:
• generating a data unit comprising one or more first training field sequences;
• and
• encoding each of the first training field sequences with a pseudo-random spreading code based on an addressee of the data unit;
• and
• transmitting means for transmitting the data unit over a wireless channel.

An apparatus for wireless communication comprising:

• receiving means for receiving at least a portion of a data unit comprising one or more first training field sequences, the one or more first training field sequences encoded with a pseudo-random spreading code based on an addressee of a data unit;
• and
• processing means for:
• determining whether the pseudo-random spreading code is associated with the receiver;
• and
• refraining from decoding a portion of the data unit when the pseudo-random spreading code is not associated with the receiver.

An apparatus for wireless communication comprising:

• receiving means for receiving a data unit comprising one or more first training field sequences;
• and
• processor means for:
• determining whether the data unit comprises one or more differentially encoded symbols,
• the receiving means further for receiving one or more second training field sequences when the data unit does not comprise one or more differentially encoded symbols.

A non-transitory computer-readable medium comprising code that, when executed, causes an apparatus to:

• generate a data unit comprising one or more first training field sequences;
• encode each of the first training field sequences with a pseudo-random spreading code based on an addressee of the data unit;
• and
• transmit the data unit over a wireless channel.

A non-transitory computer-readable medium comprising code that, when executed, causes an apparatus to:

• receive at least a portion of a data unit comprising one or more first training field sequences, the one or more first training field sequences encoded with a pseudo-random spreading code based on an addressee of a data unit;
• determine whether the pseudo-random spreading code is associated with the apparatus;
• and
• refrain from decoding a portion of the data unit when the pseudo-random spreading code is not associated with the apparatus.
