Abstract: Embodiments of the present disclosure describe systems, devices, and methods that may provide channel estimation and compensation in high speed scenarios, which may include user equipment carried on a high speed train. Embodiments may employ cell-specific reference signal (CRS)-based time-domain channel estimation and compensation.

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: An apparatus of an evolved NodeB (eNB) comprises one or more baseband processors to encode measurement gap configuration information including a measurement gap configuration information element MeasGapConfig to configure a network controlled small gap (NCSG) pattern for a user equipment (UE) device if the UE requires an NCSG and the UE is not configured with a primary secondary cell (PSCELL), and a memory to store the measurement gap configuration information.

Abstract: A UE may estimate the power headroom value when using shortened Transmission Time Intervals (sTTI). In one implementation, the power headroom value may be calculated based on an estimation of the UE transmission power over two or seven OFDM symbols. Alternatively or additionally, the power headroom value may be calculated based on an estimation of the UE transmission power over the period of an sTTI. Alternatively or additionally, the power headroom value may be calculated based on an average of the UE transmission power over multiple sTTI periods in a subframe. Alternatively or additionally, the power headroom value may be calculated based on a maximum or minimum of the UE transmission power measured over multiple sTTI periods in a subframe. Alternatively or additionally, the power headroom value may be calculated based on UE transmission power measured in the first or the last sTTI period in a subframe.
