Abstract:
Aspects describe utilizing a dedicated reference signal for supporting Network MIMO, distributed MIMO, Coordinated MultiPoint, and the like. A data modulation symbol is transmitting in the same direction as a pilot modulation symbol is transmitted. Two or more wireless devices can coordinate communications such that transmission of the same pilot modulation symbol and the same data modulation symbol are transmitted to a device in different directions, each direction associated with a wireless device and intended for a particular mobile device. Cluster-specific scrambling and/or user-group specific scrambling can be employed and a scrambling code can be communicated prior to transmission of the pilot modulation symbols and data modulation symbols.
