Abstract

A method for communication in a telecommunications cell is provided. The method includes transmitting, by an eNB, a UE-specific SRS to a specific UE in the cell via at least one TP. The method further includes receiving, by the eNB, a message from the UE, wherein the message includes information on a downlink channel from the TP to the UE, based on a measurement by the UE of the UE-specific SRS.
