METHOD AND APPARATUS FOR MAPPING A PLURALITY OF LAYERS TO A PLURALITY OF ANTENNA PORTS IN A WIRELESS COMMUNICATION SYSTEM

摘要

Provided are a method and apparatus for allocating a plurality of layers to a plurality of antenna ports in a wireless communication system. The method comprises: mapping the plurality of layers to the respective antenna ports; and mapping demodulation reference signals (DMRS) of the plurality of layers to a first code division multiplexing (CDM) set or to a second CDM set, and transmitting the signals via the plurality of antenna ports.
