Abstract:
Apparatuses and methods of advertising antenna ports to UEs is provided. In an aspect, a device may receive an advertisement regarding transmit antenna ports for legacy UE operation and transmit antenna ports for advanced UE operation. The advertisement may indicate a number of transmit antenna ports set for legacy UE operation and a different number of transmit antenna ports set for advanced UE operation. The device may also receive all control channels for legacy and advanced UE operation via the transmit antenna ports for legacy UE operation, and receive first reference signals via the transmit antenna ports for legacy UE operation and second reference signals via the transmit antenna ports for advanced UE operation. The first reference signals are received in all subframes, and the second reference signals are received in a subset of all the subframes based at least in part on a subframe configuration.
