METHOD FOR CONFIGURING ORTHOGONAL CHANNEL NOISE GENERATION OVER L2-L1 INTERFACE
A method of implementing Orthogonal Channel Noise (OCN) testing in a wireless network for fully loaded conditions in the absence of actual user equipment (UE) loads, said wireless network including a radio unit (RU), a Layer 1 module, and a Layer 2 module connected to the Layer 1 module over a message-based interface, the method comprising: sending, by the Layer 2 module, OCN parameters to the Layer 1 module via a Downlink Transmission Time Interval request (DL_TTI.request) message; and configuring, by the Layer 1 module, the RU using the OCN parameters. In the method, i) the DL_TTI.request message contains isOCNsConfigured parameter; and ii) in the case the isOCNsConfigured parameter is set to TRUE, then the DL_TTI.Request message additionally contains OCNs configuration (OCNsConfig) information.
