Abstract:
Technologies described herein provide mechanisms for a legacy UE traveling at a high speed (e.g., in a high speed train) to estimate the opposite Doppler shifts separately for different RRHs in an SFN so that the UE can more effectively receive a payload assigned by the SFN. In addition, the present disclosure provides UE signal process mechanisms to improve HST receiver performance such that good demodulation performance can be achieved without significant impacts on UE implementation. The present disclosure provides a specific framework to improve cellular SFN system operation using a combination of an SFN data signal transmissions from different RRHs and orthogonal non-SFN reference signal transmissions from different RRHs. A UE may estimate a propagation channel for each RRH using a reference signal and use this information to improve the demodulation of the combined SFN data signal.

Claim (Index 39):
The non-transitory computer-readable medium of  claim 38 , further containing instructions thereon that, when executed by the one or more processors, perform the following:\n determining that a channel link to the first RRH has a higher received power level than a channel link to the second RRH based on the one or more channel parameters for the first physical-channel transmission and based on the one or more channel parameters for the second physical-channel transmission; suppressing the channel link to the second RRH as interference; and demodulating the payload using the one or more channel parameters for the first physical-channel transmission.
