blocks with the considered modulation scheme in the kth subframe and Ndl is the number of allocated downlink subframes in one frame. The EVM measurements start on the third symbol of a slot, when the first symbol of that slot is a downlink symbol. The unwanted emissions consist of OOB emissions and spurious emissions according to ITU-R definitions. In ITU-R definition, OOB emissions are unwanted emissions immedi- ately outside the BS channel bandwidth resulting from the modulation process and nonline- arity in the transmitter analog components but excluding spurious emissions. Spurious emissions are emissions which are caused by unwanted transmitter effects, such as harmo- nics, parasitic, intermodulation products, and frequency conversion products, but exclude OOB emissions [5]. The ITU-R defines the boundary between the OOB and spurious emission domains as a fre- quency separation relative to the center of the carrier by 2.5 X (or 250%) of the NR channel bandwidth. Any emission outside the channel bandwidth which occurs in the frequency range separated from the assigned frequency of the emission by less than 2.5 times the channel bandwidth of the emission will generally be considered an emission in the OOB domain. However, this frequency separation may be dependent on the type of modulation, the maximum symbol rate in the case of digital modulation, the type of transmitter, and fre- quency coordination factors. For example, in the case of some digital, broadband, or pulse- modulated systems, the frequency separation may need to differ from the 2.5 factor. The transmitter nonlinearities may also spread in-band signal components into the frequency band of the OOB frequency range. Furthermore, the transmitter oscillator sideband noise also may extend into that frequency range. Since it may not be practical to isolate these emissions, their level will tend to be included during OOB power measurements. All emissions, including intermodulation products, conversion products, and parasitic emis- sions, which fall withi
