==BUFFER STATUS REPORT SIGNALING BOTH BUFFERED UPLINK TRAFFIC AND BUFFERED DIRECT LINK TRAFFIC - A simplified explanation of the abstract==


*This abstract for appeared for US patent application  number 18005036 Titled 'BUFFER STATUS REPORT SIGNALING BOTH BUFFERED UPLINK TRAFFIC AND BUFFERED DIRECT LINK TRAFFIC'

==Simplified Explanation==

The abstract describes how an 802.11ax access point (AP) manages the transmission opportunities for both uplink and downlink transmissions between the AP and non-AP stations. It also discusses the allocation of resources for direct link transmissions between non-AP stations. In order to efficiently schedule these transmissions, the AP needs to know the needs of the non-AP stations. The buffer status report (BSR) is used to provide information about the amount of buffered uplink traffic. The BSR is modified to include additional subfields that indicate the presence of buffered direct link traffic and provide more information about its quantity.


==Original Abstract Submitted==

An 802.11ax access point, AP, manage a granted transmission opportunity to schedule multi user uplink and downlink transmissions with non-AP stations. Resource units may also be allocated to non-AP stations for direct link, DiL, transmissions. To efficiently arbitrate between scheduling new MU UL transmissions or DiL transmissions, the AP must know the needs of the non-AP stations. The buffer status report, BSR, either solicited or unsolicited, provides an ACI Bitmap subfield and a Delta TID subfield to signal a number of TIDs for which buffered uplink traffic is declared. The BSR is amended so that these two subfields further signal, in addition to the buffered UL traffic, when there is buffered DiL traffic. Other subfields may provide more information on the amount of buffered DiL traffic.
