Patent ID: 8467818

Claim:
A communication system, comprising: a radio transceiving layer, comprising one or multiple radio transceiving node combinations, wherein a radio transceiving node in each radio transceiving node combination comprises at least one type of the following: a macro cell radio unit, a Pico cell radio remote unit, and a Pico cell baseband and radio unit; a local computing layer, comprising one or multiple local computing nodes, wherein each local computing node is connected to radio transceiving nodes in one or multiple neighboring radio transceiving node combinations, and configured to execute all communication processing or a first part of communication processing of a first cell corresponding to a first radio transceiving node combination connected to one of the local computing nodes; and a centralized computing layer, comprising one or multiple centralized computing nodes, wherein each centralized computing node is connected to the one or multiple local computing nodes in the local computing layer, and configured to execute a second part of the communication processing of a second cell corresponding to a second radio transceiving node combination connected to the one or multiple local computing nodes if the local computing node executes the first part of the communication processing, wherein the all communication processing comprises the first part of the communication processing and the second part of the communication processing.
