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.

Abstract: A method for detecting a transmission from an interfering radio cell includes: receiving a signal comprising transmissions from a serving radio cell and from a plurality of interfering radio cells, wherein a reference symbol of a transmission from at least one interfering radio cell of the plurality of interfering radio cells is colliding with a reference symbol of a transmission from the serving radio cell; generating a set of transmission signal hypotheses, each of which is dependent on at least one interferer parameter of the at least one interfering radio cell; obtaining at least one interferer radio cell identifier; and detecting a transmission from at least one interfering radio cell of the plurality of interfering radio cells in the received signal based on the at least one interferer radio cell identifier and the set of transmission signal hypotheses.

Abstract: Embodiments can relate to transmitting or processing a demodulation reference signal; the method comprising generating a demodulation reference signal, spreading an instance of the demodulation reference signal using OCC-2 for a transmission associated antenna port 7, spreading an instance of the demodulation reference signal using OCC-4 for a transmission associated antenna port 11, and co-scheduling transmission or output of the spread instances of the demodulation reference signals.

Abstract: Embodiments of the present disclosure describe methods, apparatuses, storage media, and systems for UE baseband-demodulation-performance tests in new radio (NR). An over-the-air (OTA) test environment with optimized signaling over the test interface by enabling feedback in the test system may achieve adequate baseband emulation of multipath utilizing NR reference signals. Various embodiments describe how to realize a test loop initialization and achieve better test certainty and controllability over OTA tests.
