Abstract: The present disclosure provides a method and apparatus for communicating data packets in a cloud cell. In one embodiment, a network node from which data packets are received is identified by the BS. If the data packets are received from a data gateway, a network node to which the data packets to be sent is identified. If the data packets are to be sent to a slave BS, partial processing is performed on the data packets by the master BS. Furthermore, partially processed data packets are transmitted to the slave BS so that the slave BS performs complete processing on the partially processed data packets and transmits the completely processed data packets to the MS. If the data packets are to be sent to the MS, then complete processing of the data packets is performed by the BS and transmitted to the MS.
