Abstract
Spatial reuse is provided. A device can identify first symbols orthogonal to second symbols, responsive to a receipt of an indication, from a second device, of a transmission of a second message including the second symbols. The device can transmit a first message including the first symbols, simultaneously with the transmission of the second message.
Claims20
A device, comprising:
- a circuit configured to:
- identify, from a first signal, a first long training field (LTF) symbol set associated with a first source and a second LTF symbol set associated with a second source;
- determine, using an orthogonality between the first LTF symbol set and the second LTF symbol set, a characteristic of a signal path;
- and
- determine a content of a second signal using the characteristic of the signal path.

A system, comprising:
- a first access point (AP) of a first basic service set (BSS) configured to:
- identify a quantity of spatial streams for communication with a first station of the first BSS;
- identify a first plurality of symbols based at least on the quantity of spatial streams, responsive to a receipt of an indication, from a second AP of a second BSS, of a transmission of a second message comprising a second plurality of symbols;
- and
- transmit a first message comprising the first plurality of symbols synchronized to the transmission of the second message.

A method, comprising:
- receiving, by a first access point (AP) from a second AP, an indication of a transmission of a second message, comprising:
- a quantity of spatial streams associated with the second AP;
- and
- a transmission time of the second message;
- identifying, by the first AP, a quantity of first LTF symbols orthogonal to second LTF symbols associated with the second AP using the quantity of spatial streams;
- and
- transmitting a first message comprising the first LTF symbols, based at least on the transmission time of the second message.
