Algorithm 2

Downlink adaptive adjustment for different traffic profiles.
Downlink Adaptive Adjustment
IF user burst profile = 64-QAM 3/4
 Allocate or adjust the bandwidth multiplied by adjust value of 𝑄 6 4 - Q A M 3 / 4
 based on the downlink adaptive bandwidth scheme
ELSE IF user burst profile = 64-QAM 2/3
 Allocate or adjust the bandwidth multiplied by adjust value of 𝑄 6 4 - Q A M 2 / 3
 based on the downlink adaptive bandwidth scheme
ELSE IF user burst profile = 16-QAM 3/4
 Allocate or adjust the bandwidth multiplied by adjust value of 𝑄 1 6 - Q A M 3 / 4
  based on the downlink adaptive bandwidth scheme
ELSE IF user burst profile = 16-QAM 1/2
 Allocate or adjust the bandwidth multiplied by adjust value of 𝑄 1 6 - Q A M 1 / 2
  based on the downlink adaptive bandwidth scheme
ELSE IF user burst profile = QPSK 3/4
 Allocate or adjust the bandwidth multiplied by adjust value of 𝑄 Q P S K 3 / 4
 based on the downlink adaptive bandwidth scheme
ELSE IF user burst profile = QPSK 3/4
 Allocate or adjust the bandwidth multiplied by adjust value of 𝑄 Q P S K 1 / 2
 based on the downlink adaptive bandwidth scheme
