APPARATUS AND METHOD FOR ALLOCATING COMMON REFERENCE SIGNAL PORTS IN WIRELESS COMMUNICATION SYSTEMS

摘要

The present invention relates to a method for allocating, by a central server, a common reference signal port to a plurality of transmitting units in a wireless communication system in which the central server controls the plurality of transmitting units. A combination of common reference signal ports is set for each case where at least two common reference signal ports can be allocated to each of the plurality of transmitting units. The combination of common reference signal ports is selected for the case where a terminal does not distinguish a common reference signal received from the different transmitting units from the combinations of common reference signal ports for all the cases, in consideration of actual information measured by the terminal or location information on the transmitting units. At least two common reference signal ports are allocated to each of the plurality of the transmitting units according to the selected combination of common reference signal ports. One common signal port from among the two or more common reference signal ports is commonly allocated to each of the plurality of transmitting units.
