Abstract
Systems and methodologies are described that facilitate providing flow control feedback for controlling downlink data transmission rates. Various schemes can be utilized to send the flow control feedback from an access terminal to a base station. For example, a control PDU (e.g., MAC control PDU, PDCP control PDU) can be generated based upon a level of resource utilization of the access terminal, and sent to the base station for controlling the downlink data transmission rate. Following this example, a type of control PDU, a value included within the control PDU, etc. can be selected as a function of the level of resource utilization. By way of another illustration, a CQI report that includes a value selected as a function of the level of resource utilization associated with the access terminal can be generated and transmitted to the base station for controlling the downlink data transmission rate.
