DISTRIBUTED BASE STATION WITH FREQUENCY DOMAIN INTERFACE ON WHICH SIGNAL SUBSPACE VARIES ACCORDING TO FREQUENCY BIN |
摘要 |
A method and apparatus is disclosed for determining a signal subspace in a communications system. A remote apparatus obtains signal streams from antenna elements or signal streams from antenna beams. Based on the obtained signal streams, the apparatus selects a signal subspace for a user, the signal sub-space having a dimension M. Based on the selected signal subspace, the apparatus transmits, via an interface to a central apparatus, M streams of post-fast-Fourier-transform data, the interface being capable of transmitting a different sub-space for different frequency bins. |
