Downlink flow control
First Claim
1. A method, comprising:
- detecting a level of resource utilization of a hardware resource on an access terminal;
determining, based upon the level of resource utilization, that the hardware resource cannot support a downlink data transmission rate;
generating a channel quality indicator report that includes a selected value selected as a function of the level of resource utilization of the hardware resource on the access terminal, wherein the channel quality indicator report comprises a request to reduce the downlink data transmission rate to temporarily mitigate hardware resource requirements for the access terminal;
selecting a first flow control code word for inclusion in the channel quality indicator report to reduce the downlink data transmission rate employed by a base station, the first flow control code word being reserved in a channel quality indicator code space;
selecting a second flow control code word for inclusion in the channel quality indicator report to increase the downlink data transmission rate employed by the base station, the second flow control code word being reserved in the channel quality indicator code space; and
transmitting the channel quality indicator report that includes the selected value to the base station.

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.
