Abstract
This disclosure describes systems, methods, and devices related to signaling and use of multiple transmission chains. A device may determine bits indicative of eight or fewer spatial streams. The device may encode the bits by generating an indication of more than eight spatial streams. The device may determine one or more fields of a frame, the one or more fields including the encoded bits. The device may send the frame.
Claims20
A device, the device comprising storage coupled to processing circuitry, the processing circuitry configured to:
- determine four bits indicative of spatial streams;
- encode the four bits, wherein to encode the four bits comprises to generate a first indication of a first number of spatial streams up to eight spatial streams using three of the four bits, and a second indication of a second number of either zero or eight additional spatial streams using a fourth bit of the four bits, wherein the first indication of the first number of spatial streams is encoded in a Control Information subfield of an Operating Mode Control Field, the Control Information subfield comprising a Channel Width indication and a Disable Uplink Multi-User indication;
- determine one or more fields of a frame, wherein the one or more fields comprise the Operating Mode Control Field;
- and
- cause to send the frame, the frame comprising the four encoded bits.
A non-transitory computer-readable medium storing computer-executable instructions which when executed by one or more processors result in performing operations comprising:
- determining four bits indicative of spatial streams;
- encoding the four bits, wherein encoding the four bits comprises generating a first indication of a first number of spatial streams up to eight spatial streams using three of the four bits, and a second indication of a second number of either zero or eight additional spatial streams using a fourth bit of the four bits, wherein the first indication of the first number of spatial streams is encoded in a Control Information subfield of an Operating Mode Control Field, the Control Information subfield comprising a Channel Width indication and a Disable Uplink Multi-User indication;
- determining one or more fields of a frame, wherein the one or more fields comprise the Operating Mode Control Field;
- and
- causing to send the frame, the frame comprising the four encoded bits.
A method comprising:
- determining, by processing circuitry of a device, four bits indicative of spatial streams;
- encoding the four bits, by the processing circuitry, wherein encoding the four bits comprises generating a first indication of a first number of spatial streams up to eight spatial streams using three of the four bits, and a second indication of a second number of either zero or eight additional spatial streams using a fourth bit of the four bits, wherein the first indication of the first number of spatial streams is encoded in a Control Information subfield of an Operating Mode Control Field, the Control Information subfield comprising a Channel Width indication and a Disable Uplink Multi-User indication;
- determining, by the processing circuitry, one or more fields of a frame, wherein the one or more fields comprise the Operating Mode Control Field;
- and
- causing to send, by the processing circuitry, the frame, the frame comprising the four encoded bits.
