Cross Indication of Queue Size in a Reverse Direction Protocol

摘要

This disclosure describes systems, methods, and computer-readable media related to cross indication of queue size in a reverse direction protocol. In some embodiments, a reverse direction (RD) grantor may transmit a frame to an RD responder. The RD responder may identify data to be transmitted to the RD grantor based on the received frame. The RD responder may generate a frame that may comprise a plurality of sub-frames. The RD responder may set a sub-field in each of the sub-frames indicating whether there is data to transmit. The RD responder may also set a second sub-field that may indicate a priority or traffic stream associated with the data to be transmitted. The RD responder may transmit the frame (and associated sub-frames) to the RD grantor.

主权项

1. A computer-readable medium storing computer-executable instructions which, when executed by a processor, cause the processor to perform operations comprising:
receiving, by a first user device comprising one or more processors, a first frame from a second user device; determining, by the first user device, a value of a reverse direction grant (RDG) field of the first frame is indicative of the second user device initiating a grant of time to the first user device during a transmission opportunity (TxOP) to initiate a frame exchange sequence with the first device in a wireless medium; identifying, by the first user device, data to be transmitted to the second user device; generating, by the first user device, a second frame comprising a plurality of sub-frames, wherein each of the plurality of sub-frames is associated with a portion of the data to be transmitted; setting, by the first user device, a first value of a subfield of at least one of the plurality of sub-frames to indicate that there is data to be transmitted; setting, by the first user device, a second value of a second subfield to indicate a user priority or a traffic stream identifier associated with the portion of the data to be transmitted by the first user device; and transmitting, by the first user device, the second frame comprising the plurality of frames to the second user device.
