METHOD AND APPARATUS FOR ALLOCATING REFERENCE SIGNAL PORT IN WIRELESS COMMUNICATION SYSTEM

摘要

Provided are a method and apparatus for allocating a DMRS(DeModulation Reference Signal) port in a wireless communication system. A base station: respectively allocates the DMRS port to a plurality of nodes by the number of layers used in each node; maps the DMRS port allocated to each node to a resource element within a RB (Resource Block); and transmits DMRS through the DMRS port allocated to each node. The plurality of nodes have the same cell ID(identifier) and the DMRS ports allocated to neighboring nodes in the plurality of nodes do not overlap each other.
