There are folowing AMC strategies are available:

• Normal - represents a balance between the error rate and throughput values.
• Conservative - assumes using higher CINR thresholds in order to minimize the error rate.
• Agressive - lowers the thresholds in order to use higher modulation levels and thus increase the throughput.

Frame period affects the following wireless link metrics:

• The greater frame period the more payload will be transmitted in one frame. Greater values increase latency.
• The lower frame period the less payload will be transmitted in one frame. Lower values decrease latency.

Please note that frame period value is strongly depends on interference conditions. If larger frames will be dropped then larger payload is lost and system performance is decreased significantly. If smaller frames will be dropped then smaller payload is lost and system performance is decreased not so significantly.

Guard interval is intended for intersymbol interference elimination. One of the causes of intersymbol interference is multipath propagation in which a wireless signal from a transmitter reaches the receiver via multiple paths. Guard interval affects payload size. So it should be increased only in case of intersymbol interference.
