User Manual 1173.9628.02 ─ 16
3GPP compliant RMCs allow only specific combinations of cell bandwidth, number
of allocated RBs, RB position and modulation type. User-defined channels provide
more flexibility concerning the allowed combinations.
For configuration, see
chapter 2.4.12.6, "User-Defined Channel Configuration"
on page 182.
Option R&S CMW-KS510 is required.
●
User-defined TTI-Based
Like "User-defined Channels", but settings can be configured individually per TTI
(subframe).
For configuration, see
chapter 2.4.1.7, "TTI-Based Channel Configuration"
on page 105.
Option R&S CMW-KS510 is required.
●
Fixed CQI
Provides a downlink signal with CQI index and RB allocation configurable individu-
ally per TTI. The uplink signal is the same as for "User-defined TTI-Based".
For configuration, see
chapter 2.4.1.7, "TTI-Based Channel Configuration"
on page 105.
Option R&S CMW-KS510 is required.
●
Follow WB CQI / PMI / CQI-RI / CQI-PMI-RI
The "Follow..." scheduling types provide a downlink signal configured according to
the values reported by the UE. The scheduling types are available depending on
the transmission mode:
–
Follow CQI (TM 1 to 7)
–
Follow PMI (TM 4 and 6)
–
Follow CQI and RI (TM 3)
–
Follow CQI, PMI and RI (TM 4)
The uplink signal is the same as for "User-defined TTI-Based".
For configuration, see
chapter 2.4.1.7, "TTI-Based Channel Configuration"
on page 105.
Selecting these scheduling types also sets the configured TDD UL-DL configura-
tion to 2 and enables CQI reporting.
The "Follow..." scheduling types can only work correctly, if the UE sends the corre-
sponding reports. For carrier aggregation, configure the CQI reporting settings, so
that reports for the individual carriers arrive in different subframes. Otherwise, the
"follow" mechanism will not work. See also
chapter 2.4.13, "CQI Reporting"
on page 184.
For "Follow CQI", option R&S CMW-KS510 is required. For the other "Follow..."
scheduling types, option R&S CMW-KS510/-KS512 is required (without CA/with
CA).
●
SPS
Semi-persistent scheduling (PCC only). A configured RB allocation is granted to
the UE every n
th
subframe.
Selecting this value disables HARQ and UL dynamic scheduling for connected
DRX.
For configuration, see
chapter 2.4.1.8, "SPS Configuration"
