ABSTRACT:
Systems and methodologies are described that facilitate providing auxiliary multiple-input, multiple-output (MIMO) pilot signals to MIMO user devices in a wireless communication environment. According to some aspects, a portion of data transmission power may be reallocated for auxiliary MIMO pilot transmission during a data segment in a time slot, in order to permit a MIMO user device to perform CQI and rank prediction. Additionally or alternatively, non-MIMO pilot transmission power may be reallocated in a pilot segment in the time slot for transmission of an auxiliary MIMO pilot signal to permit the MIMO user device to demodulate data transmitted in data segments of the time slot. MIMO pilot signals may additionally be time-division multiplexed within or across time slots and may be transmitted over available Walsh codes in data and control segments.
