Abstract:
A multi-point transmission system comprising a plurality of slave nodes (300) for transmitting data to a wireless receiver is described herein. An outer feedback loop and a plurality of inner feedback loops (100) connecting the plurality of slave nodes (300) to a master node (200) controls the timing skew of each slave node (300) using measurements provided by the slave nodes (300) to substantially synchronize the receipt of the transmitted data at the wireless receiver. In so doing, the solution presented herein provides improved multi-point control for any number of transmission points, which improves capacity, and solves the potential flow control problems associated with ultra-lean transmissions.
