Abstract
A base station can communicate with a plurality of subscriber stations in a Multi-User (MU) Multiple-Input Multiple-Output (MIMO) system. The base station includes a transmitter and plurality of antenna configured to transmit control information. The base station can transmit a resource block to a first subscriber station. The resource block includes at least two downlink reference signal (DRS) patterns. The base station can assign a first DRS pattern for use by the first subscriber station. The base station informs the subscriber station regarding the assignment by reserving a state in a downlink grant. In response, the subscriber station can utilize the first DRS pattern as a pilot resource element and, optionally, avoid other DRS patterns.
