context: and channel estimation algorithms. Figure A.2.1-2 shows the channel estimation error validation results in a single-user simulation case, for different channel conditions and DMRS types, where the solid curves show the statistics of collected normalized channel estimation error which is calculated is . It can be observed that the variance predicted by the error model matches well the variance of the actual estimation. Figure A.2.1-2: Channel estimation error model (TDL-C 300ns) So for PHY abstraction for realistic channel estimation, we can replace the channel by HR in Eq. (A.2.1-7), where the channel estimation error is modelled based on Eq. (A.2.1-8). Then we can use HR to calculate the weight of the linear MMSE receiver with Eq. (A.2.1-3). Finally the corresponding pp-SINR can be calculated based on Eq. (A.2.1-5), where ideal channel is still used for the target signal and the interfering signal. The HR should also be used in the interference cancellation(IC) procedure to model the
description: HR refers to a parameter representing Hand Right (Hand Phantom Only) in the context of channel estimation error modeling for MMSE-Hard IC receiver. It is used to calculate the weight of the linear MMSE receiver and pp-SINR.
explanation: The classification as a Parameter is based on its role in the provided context, where HR is described as an input for equations (A.2.1-7) and (A.2.1-8), used to model channel estimation error and calculate weights for the linear MMSE receiver.
