Abstract: A mobile terminal device includes a receiver circuit and a processing circuit. The receiver circuit is configured to receive a plurality of reference signal patterns from a plurality of transmission locations, wherein each of the plurality of reference signal patterns corresponds to a respective transmission location of the plurality of transmission locations. The processing circuit is configured to determine a synchronization offset estimate for each of the plurality of transmission locations based on the plurality of reference signal patterns to generate a plurality of synchronization offset estimates; determine if a minimum-valued synchronization offset estimate of the plurality of synchronization offset estimates satisfies predefined criteria; and determine a reception time window for processing data based on the minimum-valued synchronization offset estimate if the minimum-valued synchronization offset estimate satisfies the predefined criteria.

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.
