| 摘要 |
<p>The invention relates to a method for wireless cellular indoor communications, the method comprising at least one base station (Bs) connected to a cell management unit (CMU) through a first digital connection interface (M), the cell management unit connected to at least one RF hub (RFH. RFH2) through a second digital connection interface (i2), and the at least one RF hub connected to at least one remote radio head (RH1 to RH5) through a third digital connection interface (i3), the at least one remote radio head providing service in a certain cell area (C1, C2) inside a confined environment, and the cell management unit (CMU) comprising means for providing efficient load balancing at and between base stations through adaptive cell reconfiguration; means for mapping carriers, time, frequency or time-frequency allocations to individual radio heads; means for alignment of individual delays accumulated on the digital connections between the cell management unit and each of the radio heads; means for synchronization of the signals between the cell management unit and the individual remote radio heads; and means for failure detection of the individual digital links between the cell management unit and the remote radio heads.</p> |
