摘要： Briefly, in accordance with one or more embodiments, mobile station or user equipment receives pilot signals from two or more infrastructure nodes in a distributed antenna system, and calculates phase or timing information, or combinations thereof, from the pilot signals. The mobile station feeds back the phase or timing information, or combinations thereof, to the infrastructure nodes, and then receives one or more subsequent transmissions from the infrastructure nodes with phase shift or timing adjustments, or combinations thereof, calculated by the infrastructure nodes and applied to the spatial streams transmitted by the infrastructure nodes.

摘要： An apparatus includes a processor a channel state information (CSI) module operative on the processor to evaluate channel state information for a multiplicity of transmission points and to allocate a selection of channel state information reference signals (CSI-RS) to an uplink sub-frame allotted for transmitting channel quality/precoding matrix index/rank indicator (CQI/PMI/RI) information to a transmission point. The apparatus may further include a wireless transceiver operative to transmit the selection of CSI-RS in the uplink sub-frame to the transmission point in a wireless network, and receive information from the transmission point in response to the CSI-RS and a digital display operative to present the information received from the transmission point.
