Abstract

Certain aspects of the present disclosure provide techniques and apparatus for transmitting, receiving, and acknowledging MAC protocol data units (MPDUs), allowing single bits in a Block Acknowledgment (BA) bitmap to acknowledge receipt of multiple MPDUs. As a result, a greater number of MPDUs may be acknowledged than if each bit acknowledged only a single MPDU. By reducing the overhead associated with a re-transmission bitmap, a greater number of MPDUs may be aggregated, thereby increasing overall throughput.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Patent Application No. 61 / 374,885 (Attorney Docket No. 102596P1 ), filed September 3, 2010, which is incorporated herein by reference. technical field [0003] In general, certain aspects of the invention relate to wireless communications, and in particular, to sending, receiving and acknowledging Media Access Control (MAC) Protocol Data Units (MPDUs). Background technique [0004] To address the ever-increasing bandwidth demand required by wireless communication systems, different schemes are being developed to enable multiple user terminals to communicate with a single access point by sharing channel resources while achieving high data throughput. Multiple-Input Multiple-Output (MIMO) technology represents one such scheme that has recently emerged as a popular technique for next-generation communication systems. MIMO technology has been adopted in several emerging w...
