# Energy Saving Algorithm Pseudocode

## Energy Saving Algorithm
### On Saving Model - turn off cell?

1. Initial network environment(Random Access).
2. Collect and analyse all cell measurements/parameters.
3. If　the number of RRC connection establishment attempts < Threshold? then ??
4. If fitness on booster cells < Low threshold and candidate cell will take.
5. Set a turn off cell configuration.
6. Send configuration (action??) to RIC platform.
7. Follow configuration state of switch cell(s).
8. Repeat step2-step8.

### On Non-Saving Model

1. Initial network environment(Random Access).
2. Collects and analyse all cell measurements.
3. If　number of RRC connection establishment attempts > Threshold?
4. If **traffic** fitness on macro cell > High Threshold.4. If **traffic** fitness on macro cell > High Threshold.
5. Sets an activation configuration.
6. Send configuration
7. Follow Configurations to active cell(s) state.
8. Repeat step2-step8.

ps. Traffic fitness is a score about the DL Total PRB Usage , RRC connection establishment, and so on.

#### Threshold design

1. Be standard "DL Total PRB Usage". *Ld*
2. Calculate Standard Deviation σ1.
3. Be RRC connection establishment attempts standardizing. *Rce*
4. Calculate Standard Deviation σ2.
5. FITNESS $`FT= \alpha\times Ld_u^c+ \beta \times Rce_u^c`$
6. User={1,2,3...,*u*} ,Cell={1,2,3...,*c*}
7. High Threshold is $` \alpha[Ld_{avg}+ σ1]+ \beta \times [Rce_{avg}+σ2] `$
8. Low Threshold is $` \alpha[Ld_{avg}- σ1]+ \beta \times [Rce_{avg}-σ2] `$
9. $` \alpha , \beta `$ are weight parameters.

### NEW
1. *Ld* is "DL Total PRB Usage".
2. Calculate "DL Total PRB Usage" standard deviation σ1.
3. *Rce* is the number of RRC connection establishment attempts is
4. Calculate "the number of RRC connection establishment attempts" standard deviation σ2.
5. High threshold of RRC connection establishment attempts is $[Rce_{avg}+σ2]$ ,Low Threshold of RRC connection establishment attempts is $[Rce_{avg}-σ2]$
6. High Threshold of
