20140241258 | COORDINATED DIGITAL RADIO DISTRIBUTION ARCHITECTURE - A communication system architecture is provided, having an aggregator, arranged to centralize the access units and coordinate the radio signals of access units of different types digitally, and remote radio units configured to be modularly connectable to different types of radio elements that correspond to the access units and arranged to communicate with the aggregator digitally. Radio signals are scheduled and delivered with respect to the types of the access units and of the radio elements, and the aggregator is further arranged to handle distribution and combining of the radio signals digitally. The aggregator further comprises a controller arranged to continuously optimize communication with respect to the access units and user mobile communication devices by applying a decision process to cost functions that depends on communication parameters to derive specified dynamically changing parameters, and to manage the aggregator dynamically with respect thereto. | 08-28-2014 |
20140242999 | COORDINATING DISTRIBUTED RADIO VIA REMOTE UNITS - Provided herein is a dynamically coordination of a distribution of radio signals via distributed remote radio units, with respect to changing numbers and locations of user equipment. A distributing and combining unit combines uplink radio signals from the remote radio units and distributes downlink radio signals from the access unit according to dynamically changing specified criteria. A measurement unit measures performance indicators of the communication between the remote radio units and the mobile communication devices into a matrix of performance indicator values, calculates cost functions therefrom and generates output execution parameters by applying a decision process based on the calculated cost function. Communication criteria are dynamically updated according to the generated output execution parameters and the process is continuously iterative. The invention allows incorporating “smart” capabilities into legacy networks without any major physical changes of the network. | 08-28-2014 |
