context: Inband emissions (co-channel) RAN4 has decided to use the IBE requirements from TS 38.101-2 clause 6.4.2.3.4 (power class 3 UE). It is understood these requirements are minimum performance requirements as opposed to typical requirements. RAN4 has agreed to use typical requirements for the UE parameters, however, no final conclusion has been made regarding typical values. Consequently, the formulation from the current specification is being utilized. It should also be assumed the LO location is in the center of the channel for the purposes of system studies in RAN4. The LO location is important as it allows placement of the image. Analysis indicates that the IBE interference is higher and dominates the sub-band in-channel selectivity, Apart from the selectivity, the degradation can be caused by transmitter leakage from the UL sub-band into the DL sub-band. For co-channel case, the leakage was agreed to be modelled using IBE based model. Additionally, the IQ image contribution for the
description: In-Band Emission (IBE) is a critical network attribute that describes the amount of power radiated by a transmitter within its own assigned frequency band. It's crucial for minimizing interference with other signals operating on the same frequency.
explanation: IBE directly impacts network performance and spectrum efficiency.  It's a measurable parameter used to evaluate transmitter compliance with regulatory limits and ensure smooth operation within the allocated frequency bands.
