Scalable architecture for long term evolution (lte) multiple user equipment (multi-ue) simulation

A method for scalably simulating multiple long term evolution (LTE) user equipment (UE) devices, the method comprising:

• at an LTE multi-UE simulator:
• at a common public radio interface (CPRI) module, receiving downlink data from an evolved node B (eNode B) under test;
• at a downlink signal chain processing module including a common section and a UE specific section performing, in the common section, UE agnostic processing of the downlink data and performing, in the UE specific section, UE specific processing of the downlink data;
• and
• at a control digital signal processor (DSP), receiving the downlink data from the common section of the downlink module, processing the downlink data to obtain control information, and forwarding the control information to the downlink signal chain processing module, wherein the UE-specific portion performs the UE-specific processing using the control information.

A non-transitory computer readable medium having stored thereon executable instructions that when executed by the processor of a computer controls the computer to perform steps comprising:

• at an LTE multi-UE simulator:
• at a common public radio interface (CPRI) module, receiving downlink data from an evolved node B (eNode B) under test;
• at a downlink signal chain processing module including a common section and a UE specific section performing, in the common section, UE agnostic processing of the downlink data and performing, in the UE specific section, UE specific processing of the downlink data;
• and
• at a control digital signal processor (DSP), receiving the downlink data from the common section of the downlink module, processing the downlink data to obtain control information, and forwarding the control information to the downlink module, wherein the UE specific portion performs the UE specific processing using the control information.
