Abstract:
The transmitter maps an antenna port to a logical antenna port through a first virtualization. The transmitter maps the logical antenna port to a transceiver unit (TXRU) through a first operation. The transmitter maps the TXRU to a logical TXRU through a second operation. The transmitter maps the logical TXRU to a physical antenna element through a second virtualization.
