Scalable architecture for long term evolution (LTE) multiple user equipment (multi-UE) simulation

摘要

A system for scalably simulating multiple LTE UE devices includes an LTE multi-UE simulator. The simulator includes a common public radio interface (CPRI) module for receiving downlink data from an evolved node B (eNode B) under test and a downlink signal chain processing module including a common section for performing UE agnostic processing of the downlink data and a UE specific section for performing UE specific processing of the downlink data. The simulator further includes a control digital signal processor (DSP) for receiving the downlink data from the common section of the downlink signal chain processing module, for processing downlink data to obtain control information, and for forwarding the control information to the downlink signal chain processing module. The UE specific portion of the downlink signal chain processing module performs the UE specific processing using the control information.

1. A system for scalably simulating multiple long term evolution (LTE) user equipment (UE) devices, the system comprising:
an LTE multi-UE simulator distinct from an evolved node B and user equipment, the LTE multi-UE simulator comprising:
a common public radio interface (CPRI) module for receiving downlink data associated with multiple UEs simulated by the LTE multi-UE simulator from an evolved node B (eNode B) under test;a downlink signal chain processing module including a common section for performing UE agnostic processing of the downlink data and a UE specific section for performing UE specific processing of the downlink data for each of the multiple UEs simulated by the LTE multi-UE simulator; anda control digital signal processor (DSP) for receiving the downlink data from the common section of the downlink signal chain processing module, for processing the downlink data to obtain control information, and for forwarding the control information to the downlink signal chain processing module, wherein the UE specific section performs the UE specific processing using the control information.
