Abstract

System and method of cooperative multi-band wireless STA communication that enables full duplex operations. Frames are configured to carry band information and are selected to be transmitted simultaneously in multiple bands based on various constraints to avoid out-of-order delivery. For frames under a block ACK agreement, a transmit STA can specify the transmission bands for the frames in an ADDBA request frame. While a first band is transmitting a first frame under a block ACK agreement, the second band can be used to transmit a frame under the same block ACK agreement as, and from the same traffic flow with, the first frame. Otherwise, the second band can only be used to transmit a frame with a different TID than the first frame.

Claims16

Dependent claims

A method of wireless communication performed by a first wireless station (STA) comprising at least a first transceiver and a second transceiver respectively associated with a first band and a second band, the method comprising:

transmitting a first frame in said first band, wherein said first frame is associated with a traffic identifier (TID);
scheduling a first plurality of frames for transmission;
during transmission of said first frame, selecting a first next frame from said first plurality of frames for transmission in said second band, wherein said selecting comprises at least one of:
responsive to a determination that the first frame is under a block acknowledgment (ACK) agreement, selecting a frame with a same or different TID as said first frame as said first next frame;
and
responsive to a determination that the first frame is not under a block ACK agreement, selecting a frame with a same or different TID than said first frame as said first next frame;
and
transmitting said first next frame in said second band.

5 more elements

A wireless stations (STA), comprising:

a processor;
a first transceiver associated with a first band;
and
a second transceiver associated with a second band,
wherein the processor performs a method for transmitting data wirelessly over the first band and the second band, the method comprising:
transmitting a first frame in said first band, wherein said first frame is associated with a traffic identifier (TID);
scheduling a first plurality of frames for transmission;
during transmission of said first frame, selecting a first next frame from said first plurality of frames for transmission in said second band, wherein said selecting comprises at least one of:
response to a determination that the first frame is under a block acknowledgment (ACK) agreement, selecting a frame with a same or different TID as said first frame as said first next frame;
and
responsive to a determination that the first frame is not under a block ACK agreement, selecting a frame with a same or different TID than said first frame as said first next frame;
and;
and
transmitting said first next frame in said second band.
