Patent ID: 10779315

Abstract:
A wireless station may buffer data associated with one or more traffic identifiers (TIDs), and generate a media access control (MAC) protocol data unit (MPDU) including TID-specific buffer status report (BSR) information. A BSR control field may include an Access Category Identifier (ACI) bitmap and a delta TID parameter indicating a mapping of TID-specific buffer status information to a first and second queue size indicated by the BSR. In some cases, the MPDU may also include a quality of service (QoS) control field, and queue sizes indicated by the BSR control field and QoS control field may be accumulated for reporting buffer status for a TID. Additionally or alternatively, a transmitting wireless station may generate an aggregated MPDU (A-MPDU) including multiple MPDUs with different A-control fields based on a receiving a capabilities information field indicating a number of different aggregated control (A-Control) fields the receiving wireless station supports.
