摘要：
A base station is provided. The base station comprises:
a downlink transmit path comprising circuitry configured to transmit at least one reference signal in one or more subframes, each subframe comprising two slots, each slot comprising S OFDM symbols, each of the S OFDM symbols comprising N resource elements; and
a reference signal controller configured to:
apply one orthogonal code of two orthogonal codes to an antenna port of a first set of antenna ports, if the number of layers is less than or equal to a predetermined number of layers, and
apply one orthogonal code of four orthogonal codes to an antenna port of a second set of antenna ports, if the number of layers is greater than the predetermined number of layers,
wherein total number of antenna ports is based on the number of layers.
The invention also provides a subscriber station and methods for transmitting and receiving reference signals.
