METHODS OF PDCCH CAPACITY ENHANCEMENT IN LTE SYSTEMS BASED ON A TP-SPECIFIC REFERENCE SIGNAL

摘要

A method is provided for providing reference signal information in a cell including a plurality of transmission points in a wireless telecommunication system. The method comprises transmitting, by one of a subset of transmission points in the cell, at least one reference signal for demodulating a PDCCH, wherein transmitting the at least one reference signal comprises transmitting the at least one reference signal in at least one CCE reserved in a PDCCH region for transmission of the at least one reference signal.
