CSI-RS based cell discovery signal

摘要

A method of small cell discovery in a wireless network deployment using a Channel State Information Reference System (CSI-RS) is proposed. First, a wireless communication system allocates pairs of resource elements in each resource block of a subframe to a CSI-RS configuration. A first of two orthogonal cover codes is applied to the first CSI-RS. The CSI-RS is transmitted by a small cell to a user equipment (UE). The UE utilizes the CSI-RS to perform small cell discovery and measurement of the small cell.
