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 of operating a remote node in a wireless communication system includes: determining each of instantaneous channel states between host nodes and the remote node based on reference signals received from the host nodes during some of time intervals for a channel estimation; determining a host node for random access among the host nodes based on the determined instantaneous channel states; and when a value indicating a state of a channel between the determined host node and the remote node is larger than a threshold value, transmitting a signal for the random access to the host node.
