Abstract
Adaptive modulation and priority-based flow control in wireless communications are disclosed. Ingress communication traffic is modulated for transmission over a wireless communication link. A modulation rate of modulation to be applied to the ingress communication traffic is controlled by adaptive modulation. A rate at which the ingress communication traffic is received is controlled through Priority-based Flow Control (PFC), but the PFC is based on the adaptive modulation. Adaptive modulation and PFC are thus linked together. PFC messaging could be sent when a change in modulation rate due to the adaptive modulation would not meet the rate at which the ingress communication traffic is received. If a change in modulation rate due to the adaptive modulation would still meet the rate at which the ingress communication traffic is received, then PFC messaging might not be sent.
