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 a long term evolution (LTE). Various examples of the present disclosure provide a method of allocating sounding reference signal (SRS) resources. A base station of a target cell receives information of first cell edge terminals in an adjacent cell transmitted by the adjacent cell. The base station allocates SRS resources for a terminal in the target cell according to information of second cell edge terminals in the target cell and the information of the first cell edge terminals, and transmits information of the allocated SRS resources to the terminal. According to the mechanism, when there are cell edge terminals in both the target cell and the adjacent cell, it can be guaranteed that all SRS resources allocated to cell edge devices in the target cell are orthogonal to those allocated to cell edge devices in the adjacent cell. Thus, the impact of pilot contamination on system performances may be remarkably reduced.
