The simulation algorithm is implemented according to the specification outlined in Rec. ITU-R M.2101 – section 3.4.1 for downlink and section 3.4.2 for uplink. This implementation addresses both cases of IMT-2020 as the interfering and victim system.
Flowcharts describing the specific SEAMCAT implementation are provided in Annex 15.
Note that the number of UEs per BS K is not set explicitly in SEAMCAT but is derived from the user parameters 'Max. RBs per BS' (parameter M in M.2101) and 'Number of RBs per MS' (parameter n in M.2101), i.e.:
| Mathinline | ||
|---|---|---|
|
...
|
The K users are distributed randomly within the sector of each BS.
Power control is implemented similarly to OFDMA systems (see section x9.y.z10), as recommended in M.2101 section 4.1.
