---|---|---|
Number of eNBs (3 sectored) | 19 | 19 eNBs in a hexagonal pattern, each with 3 cells and wrap-around was used for full-buffer simulations and to generate the geometry (average SINR) distributions for the QoS simulations |
Propagation Model (BTS Ant Ht  = 32 m, MS  = 1.5 m) | dB, in meters | Modified Hata Urban Prop. Model @1.9 GHz (COST 231 ([59])). Modified means that pathloss is reduced by 3 dB in comparison to COST 231. This is a standard assumption (see, e.g., [58]). |
Minimum separation between eNB and UE | 35 meters | — |
Log-Normal Shadowing | Standard Deviation  = 8.9 dB | This shadowing is constant for each UE in each simulation run. The same shadowing amount will be used for all the sector antennas of a BS to a given UE. The correlation coefficient between the eNB's Tx antennas and a given UE and the eNB's RX antennas and a given UE is 1. |
Shadowing correlation across cells in an eNB | 1 | — |
Shadowing correlation across eNBs to a UE | 0.5 | — |
Number of transmit antennas | 1 | — |
Number of receive antennas | 1 | — |
Number of resource blocks | 64 | This number slightly exceeds the 10 MHz bandwidth and was selected since powers of 2 are convenient when hopping is introduced. It does not change the conclusions about the schedulers. The reader can scale the numbers down to infer exact 10 MHz bandwidth performance. |
Number of OFDM symbols per subframe | 14 | This is for normal cyclic prefix (CP). Of the 14, the first 3 are assigned to control transmissions (PDCCH, PCFICH and PHICH) |
eNB transmit power per cell | 20 Watts (43 dBm) | — |
Thermal Noise density | −174 dBm/Hz | — |
eNB and UE antenna gains | 0 dBi | — |
Site-to-site distance | 2.0 km | — |
HARQ | Synchronous, non-adaptive, incremental redundancy | — |
