摘要
Disclosed herein are various embodiments that include a method and a passive optical network (PON) for supporting a mobile network. In various embodiments, a baseband unit (BBU) is configured to measure an optical path delay from each remote radio unit (RRU) of a plurality of RRUs to the BBU during an initialization phase. The BBU synchronizes all the RRUs in the mobile system by adjusting the timing of each path based on the optical path delay between each RRU and the BBU. The BBU determines a mapping rule that maps each resource block assigned to each RRU of the plurality of RRUs to a different PON transport block. The BBU transmits the mapping rule to each RRU of the plurality of RRUs. In certain embodiments, the mapping rule may be recalculated dynamically after the initialization phase.
