Abstract

Certain aspects of the present disclosure generally relate to apparatus and methods for managing acknowledgement messages from multiple destinations for multi-user multiple-input multiple-output (MU-MIMO) transmissions. According to certain aspects, a polled block acknowledgement (BA) mechanism can be considered mandatory to an acknowledgement protocol, and a sequential (or other type of scheduled / deterministic) mechanism can be considered optional.

Description

[0001] Claiming Priority Based on 35 U.S.C. §119 [0002] This patent application claims priority to U.S. Provisional Patent Application Serial No. 61 / 376,962, entitled "Managing acknowledgment messages from multiple destinations for MU-MIMO," filed August 25, 2010, which is assigned to this application assignee, is hereby expressly incorporated by reference. technical field [0003] In general terms, certain aspects of the invention relate to apparatus and methods for managing acknowledgment messages for multi-user multiple-input multiple-output (MU-MIMO) transmissions from multiple destinations. 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...
