Non-alloc (NB-IoT)

There is a difference between Non-alloc signals for Frame Summary and Non-Alloc signals for the rest of the traces.

In the Frame Summary trace, the Non-alloc row calculations include only subcarriers that could be allocated to NPDSCH, but are not currently allocated. This is in contrast with other traces, which include any unused subcarrier (whether in control or shared channels) in the Non-alloc category.

Any subcarriers contained by a user channel which is present in the Composite Include list are considered allocated, regardless of whether the user channel has been selected for analysis and display.

For more information about Non-alloc for the other traces, see the Non-alloc section in the Composite Include topic.
