Abstract:
A network element in a first cell in a wireless telecommunication network is provided. The network element comprises a processor configured such that the network element provides uplink and downlink grants in the first cell, wherein the first cell is a low-power cell within the coverage area of a second, high-power cell, and wherein the first cell acts as a secondary cell and the second cell acts as a primary cell in a carrier aggregation mode, and wherein at least one uplink control signal is received by one of only the first cell or both the first cell and the second cell.
