Method and system for controlling downlink transmit power
Aspects of the subject disclosure may include, for example, obtaining channel cross correlation data relating to multiple user equipment (UEs) being served in a cell, wherein the channel cross correlation data comprises a correlation coefficient associated with a first UE of the multiple UEs and a second UE of the multiple UEs, identifying that the first UE is experiencing decreasing throughput, responsive to the identifying that the first UE is experiencing decreasing throughput, determining whether the correlation coefficient associated with the first UE and the second UE satisfies a correlation threshold, and, based on a first determination that the correlation coefficient does not satisfy the correlation threshold, adjusting a downlink (DL) transmit power allocation for transmissions directed to the first UE. Other embodiments are disclosed.

CHANNEL ESTIMATION USING COMPOSITE SUBCARRIERS AND COMBINED PILOTS
Techniques for minimum-mean-square-error (MMSE) channel estimator using channel-dependent composite subcarriers and combined pilots reduce computational complexity and memory usage while still achieving near optimum performance. A set of interpolation filters, that are pre-calculated for different radio propagation environments, e.g., channel state information, are stored in look up tables at the receiver and used to interpolate channel estimates for combined pilots to obtain channel estimates for individual subcarriers.
