Abstract:
1. A method for transmitting control information in a telecommunications cell, comprising: a subset of transmission points of a set of transmission points associated with an eNodeB (eNB) in the cell transmitting a unicast physical downlink control channel (PDCCH) intended only for a specific user equipment (UE) in the cell, wherein the unicast PDCCH contains at least one resource element in each resource element group, and wherein at least one resource element contains a UE-specific demodulation reference signal (DMRS) that can be used for decoding the unicast PDCCH, and wherein the decoding occurs without the use of a cell-specific reference signal broadcast by the eNB, and wherein a remainder of the set of transmission points does not transmit the unicast PDCCH.
