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.

Abstract: A channel estimation method includes receiving signals at Resource Elements (REs) designated for reference signals, converting the received signals to time-domain entries using a matched filter, organizing the entries output from the matched filter into groups by delay, determining whether an energy sum of the entries of each group is greater than a predetermined threshold, and selecting the entries belonging to the group of which the energy sum is greater than the threshold value into a candidate group for channel estimation.

Abstract: Disclosed is a 5th generation (5G) or pre-5G communication system for supporting a data transmission rate higher than that of a 4th generation (4G) communication system, such as long term evolution (LTE). The purpose of the disclosure is to detect interference between base stations in a wireless communication system, and a base station operating method can comprise the steps of: receiving signals through a resource allocated for reference signals (RSs) for interference measurement; detecting at least one RS on the basis of the signals; and determining that at least one among the RSs has been received on the basis of cross-correlation values between candidate RSs.

Abstract: The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The present invention relates to a method and an apparatus for estimating an uplink channel of a base station in a wireless communication system, comprising the steps of: estimating a position of a wireless channel tap on the basis of a sounding reference signal (SRS) received from a terminal; determining an average power value of the wireless channel tap for each link between a transmitting antenna and a receiving antenna from and to which the SRS is transmitted; and estimating an effective channel frequency response (effective CFR) of a physical uplink shared channel (PUSCH) on the basis of the position of the wireless channel tap and the average power value of the wireless channel tap.

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). A method and an apparatus for channel estimation in a wireless communication system are provided. According to various embodiments of the present disclosure, an method of a receiving apparatus in a wireless communication system includes: estimating channel tap values by using a first reference signal; and estimating an effective channel regarding a second reference signal, based on channel tap indexes corresponding to values greater than or equal to a threshold from among the channel tap values. According to various embodiments of the present disclosure, the receiving apparatus can more exactly estimate an effective channel, and can achieve a lower BLER even in a high SNR region.
