Scheduling Type UL RMC
UL reference measurement channels are intended for UL RF tests, specified in 3GPP
TS 36.521, chapter 6. You can use them for the NB-IoT multi-evaluation measurement.
The UL RMCs are defined in 3GPP TS 36.521, Annex A.2.4. The signaling application
uses the UL scheduling patterns defined there. A pattern determines which subframes
are scheduled.
In the signaling application, a UL RMC can be defined via the following set of parame-
ters:
●
Number of subcarriers (no of SC)
●
Position of the first subcarrier (start SC)
●
MCS index, determining the modulation scheme and the transport block size
●
Number of resource units (no of RU)
●
Number of repetitions
The parameter combinations supported by the R&S
CMW for NPUSCH format 1 are
listed in the following table, depending on the SC spacing.
