Abstract: In some aspects, the disclosure is directed to methods and systems for intelligent transmit power management. Output power levels may be dynamically determined responsive to REM measurements, user equipment (UE) signal reports, information received from other cells (e.g. via X2 application protocol (X2AP) or other such communication protocols), or any combination of these or other information in an iterative level conditioning and limit checking process.

Abstract: Code detection to assist a symbol-level equalizer in a receiver is described. In an embodiment, code detection uses adaptive Infinite Impulse Response (IIR) filtering to determine spreading code usage information and active code channels in a received signal. The spreading code usage information indicates if a spreading code associated with a code channel is among spreading codes used in the received signal. In another embodiment, the spreading code usage information is determined based on a forgetting factor associated with the filtering of a symbol power associated with the code channel.

Abstract: Techniques are described herein that receive communications transmitted according to different operation modes at a multi-mode, programmable receiver system. The multi-mode, programmable receiver system may receive communication signals from transmit antennas in “cells” (e.g., base station transceivers and/or the like) according to one or more operation modes, using receive antennas. The received signals may be converted and processed by various modules of the multi-mode, programmable receiver system to produce an output signal. The multi-mode, programmable receiver system includes modules that are programmable to be selectively enabled or disabled according to an operation mode in accordance with which the multi-mode, programmable receiver system operates.

Abstract: A communication device, such as a smart phone, includes logic to determine a noise power estimate. In an example, a frequency domain calculation may be used to determine noise components within the noise power estimate. Further, a product of a channel estimate and equalizer effect may be used in the determination of the levels noise components, such as, inter-symbol interference power and neighbor cell interference power.
