Abstract
The communication system is provided, where the communication system comprises multiple cluster distributed antenna system (MC-DAS) network and a controller. Each cluster in the MC-DAS comprises a cluster master (CM) and remote radio units (RRU), which are in the coverage area of the controller. The controller and the DAS clusters are synchronized using a hierarchical precision time protocol (HPTP). Each DAS cluster is configured to transmit messages independently from other DAS clusters in the plurality of DAS clusters using a distributed cyclic delay diversity (CDD) scheme with a determined length of a cyclic prefix. The controller further comprises a controller configured to transmit a message from the controller to a receiver through one or more DAS clusters of the plurality of the DAS clusters.
