Comments

It will boost serving sector & delay IRAT

SIB19

Per cell relation, from neighbor cell towards the loaded cells. To Speed HO in case of fading

(Highway,terrain,etc..)

We change it to FALSE in case of low HOSR due to large distance & overshooting

Can be changed to 320 if customer approves it for hi-cap. To reduce the blocking and lead to

less re-attempts .

Can be changed to 590 if customer approves it for hi-cap. To reduce the blocking and lead to

DL Throughput in such conditions is affected by several factors: • Cell range. (Site-To-Site Distance) • Radio conditions (signal power, path loss, SINR). Low received signal degrades the SINR in absence of a strong dominant server at edges of large cell which becomes more & more noise limited • Position of users in the cell (implies path loss, fading … etc). Location of the mobile terminal in the cell will strongly influences the data rate that can be experienced by the user. In low SINR and bad RF conditions the DL throughput will be low as a robust modulation scheme QPSK and a high amount of error correction bits is used to overcome errors introduced by the air interface
