Abstract
The present application relates to a Common Public Radio Interface, CPRI, lane controller and a method of operating thereof. The CPRI lane controller comprises a transaction counter, a symbol counter and a comparator. The transaction counter is provided for maintaining a current aggregated transactions' size, Size, representative of an accumulated size of DMA transactions performed by a DMA controller in response to symbols transferred on a CPRI link from or to the CPRI lane controller. The symbol counter is provided for maintaining a current aggregated expected symbols' size, Size, representative of an accumulated size of a sequence of transferred symbols and a currently transferred symbol. The comparator is configured to issue a symbol awareness signal, SAS, in case the current aggregated transactions' size, Size, exceeds the current aggregated expected symbols' size, Size.
