US 10,484,207 B2 · Method and apparatus for channel estimation in wireless communication system

Abstract

The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). The present disclosure provides a channel estimation method and apparatus by a reception end. The reception device includes a receiver and a controller. The receiver receives a reference signal. The controller identifies a first set of channel values for resources allocated for reference signals. The controller performs interpolation on the first set of channel values so as to identify second set of channel values for remaining resources. The interpolation method is determined based on at least one of Doppler frequency of a channel and channel quality. The controller processes received signals using the first set of channel values and the second set of channel values.

Dependent claims

A method for operating a reception device, the method comprising:

obtaining a basis expansion model (BEM) basis vector based on reference signals received from a transmission device;
obtaining at least one BEM coefficient corresponding to at least one non-zero entry of a channel impulse response (CIR) based on the BEM basis vector;
obtaining the CIR based on the at least one BEM coefficient and the BEM basis vector;
obtaining a channel frequency response (CFR) from the CIR;
and
processing received signals using the CFR.
