MCS - Modulation and Coding Scheme
SINR - Signal-to-Interference-plus-Noise Ratio
RE - Resource Element
MIMO - Multiple Input Multiple Output
UE - User equipment
CA - Carrier aggregation
CC - Component carrier
Defines how many radio resources are available to transmit data. All values standardized by 3GPP are supported.
Defines MCS which depends on channel quality (e.g. SINR) and defines how many bits can be carried by a single RE. Different signal quality leads to a different modulation. QPSK, 16QAM, 64QAM and 256QAM are supported.
Results should be considered "outdoor" speeds. Uplink speeds could be much lower indoor, especially on higher bands (≥1400MHz) due to higher path loss, lower UE RF power, smaller UE antenna, etc.
64QAM in UL
Only Cat.5, Cat.8 and Cat.13-20UL devices are capable of using 64QAM modulation in uplink. All other devices are limited to 16QAM.
Sets MIMO scheme. This parameter is taken with some inaccuracy, i.e. initial throughput is multiplied by 2 or 4 either MIMO 2x2 or MIMO 4x4 selected, respectively. In reality throughput will be a bit lower due to increased number of pilot signals. * MIMO 8x8 is available to Cat.8 UE only.
Using LTE Advanced carrier aggregation, it is possible to utilise more than one carrier and in this way increase the overall transmission bandwidth. These channels or carriers may be in contiguous elements of the spectrum, or they may be in different bands. Each aggregated carrier is referred to as a component carrier (CC). You can select additional bandwidths for up to three CCs.
CA CCs on higher bands
Check this if CCs for CA are on higher bands (>1800MHz). This setting will try to estimate a more "real world" results based on the higher path loss on higher frequencies used for the aggregation. It will recalculate the MCS for the CCs according to the selected signal strength.
