description: The Unwanted Emissions Mask (UEM) is a parameter used to define the limits for unwanted emissions in operating bands, as specified in 3GPP TS 37.809 and related specifications such as TS25.104 and TS36.104. The UEM values are determined based on the base station's maximum output power and bandwidth, with specific requirements defined for different scenarios, including LA (Licensed Assisted Access) MSR (Multi-Standard Radio) BC1 and BC2 configurations.
explanation: The context describes the UEM as a parameter used to regulate unwanted emissions in telecommunications systems. It is defined by technical specifications and its value depends on factors like base station power and bandwidth.
