    Abstract: PROBLEM TO BE SOLVED: To provide a method of reverse link (RL) data rate allocation in a high data rate system such as 1xEV-DO.
    SOLUTION: Rate shaping of a throughput profile for multiple access terminals (ATs) is performed by adjusting transition probabilities associated with a data rate allocation algorithm. The RL maximum data rate per AT is adjusted to reduce the loading in a designated area and result in rate shaping of the cell and/or sector. The maximum data rates are adjusted as a function of the FL signal to Interference and Noise Ratio (SINR), such as measured per serving sector or as a captured sum total of FL SINR. Further, the maximum data rates are adjusted as a function of differences in rise over thermal values between neighboring sectors.

    Abstract: PROBLEM TO BE SOLVED: To provide systems and methodologies that facilitate quality of service (QoS) differentiation and/or prioritization across a plurality of base stations included in wireless communication systems.SOLUTION: The system can include components and/or devices that: obtain resource allocations for cells controlled by a local base station; ascertain whether or not the resource allocations satisfy quality of service targets associated with data flows traversing through cells controlled by the local base station; and dispatch inter cell interference coordination indicators to remote base stations that have a proximate relationship defined by an X2 channel between the local base station and the remote base stations.

    Abstract: PROBLEM TO BE SOLVED: To improve operation of a media access control (MAC) layer of an access terminal.
    SOLUTION: An access terminal includes: a transmitter that transmits a reverse traffic channel to an access network; an antenna that receives a signal from the access network; a processor that performs electronic communication with a processor; and a memory. An instruction stored in the memory determines whether the current electric power allocation permission 1374 in a flow of the access terminal is the one received from the access network or not. If the current electric power allocation permission 1374 is still active, the current electric power allocation 1338a for the flow is set equally to the current electric power allocation permission 1374. If the current electric power allocation permission 1374 is not received yet, the current electric power allocation 1338a for the flow is decided.

    Abstract: Reverse Link (RL) data rate allocation in a High Data Rate (such as 1xEV-DO) system as a function of Forward Link (FL) channel quality. Rate shaping of a throughput profile for multiple Access Terminals (ATs) is performed by adjusting transition probabilities associated with a data rate allocation algorithm. The RL maximum data rate per AT is adjusted to reduce the loading in a designated area and result in rate shaping of the cell and/or sector. In one embodiment, the maximum data rates are adjusted as a function of the FL Signal to Interference and Noise Ratio (SINR), such as measured per serving sector or as a captured sum total of FL SINR. In still another embodiment, the maximum data rates are adjusted as a function of differences in rise~over-thermal values between neighboring sectors.
