Table 1 Simulation Parameters.

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.

Number of transmit antennas

Number of receive antennas

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)
