Abstract: A method and apparatus are provided. The method includes receiving a reference signal from a transceiver, estimating a time offset (TO) of the reference signal in the frequency domain based on an accumulation of subcarriers before cross-correlation, providing a TO compensated signal of the reference signal based on the estimated TO in the frequency domain, transforming the TO compensated signal into the time domain, and estimating a frequency offset (FO) based on the time domain TO compensated signal.

Abstract: A method and apparatus are provided. The method includes receiving a reference signal from a transceiver, estimating a time offset (TO) of the reference signal in the frequency domain based on a spectral phase ramp introduced by the TO, compensating the TO of the reference signal based on the estimated TO in the frequency domain by applying the spectral phase ramp to the received reference signal, and providing a TO compensated signal of the reference signal.

Abstract: Methods and apparatuses are provided in which a signal is received at a receiver. A processor of the receiver computes frequency offset (FO) inter-carrier interference (ICI) compensation, based on a real matrix part of an approximate ICI matrix and an FO estimated from the received signal. The processor applies the FO ICI compensation to the received signal in a frequency domain to produce an ICI compensated output. The processor applies a phase rotation to the ICI compensated output.

Abstract: A method and an apparatus are provided for determining whether an enhanced physical downlink control channel (ePDCCH) transmission exists for a user equipment (UE) in a subframe. The UE receives a transmission on physical downlink control channel (PDCCH) resources of the subframe. Downlink control information (DCI) is extracted from the PDCCH resources. The DCI includes at least one bit indicating whether the ePDCCH transmission exists for the UE in the subframe. The UE determines whether the ePDCCH transmission exists using the at least one bit. Additional symbols of the subframe are buffered and decoded when the ePDCCH transmission exists.
