Dynamic ASBR scheduler

A system that facilitates dynamic active set based restricted (ASBR) frequency scheduling in a wireless network environment, comprising:

• an ASBR scheduling component that determines an overall scheduling metric for each user device in the wireless network environment;
• a peak component that determines an overall channel peak desirability metric for each user device, wherein the overall channel peak desirability metric reflects the instant channel desirability on the user device's best available frequency set relative to the user device's average channel quality;
• a delay component that determines a channel delay desirability metric for each user device, wherein the channel delay desirability metric is the ratio between the maximum instant spectral efficiency over all free frequency sets, and the maximum instant spectral efficiency over all unavailable frequency sets;
• and
• a processor that controls at least one of the ABR scheduling component, the peak component, and the delay component.

An apparatus that facilitates scheduling frequency assignments for user devices in a wireless communication environment, the apparatus comprising:

• means for determining a fairness metric for each user device in the communication environment;
• means for determining an overall channel peak desirability metric for each user device, wherein the overall channel peak desirability metric reflects the instant channel desirability on the user device's best available frequency set relative to the user device's average channel quality;
• means for determining a channel delay desirability metric for each device, wherein the channel delay desirability metric is the ratio between the maximum instant spectral efficiency over all free frequency sets, and the maximum instant spectral efficiency over all unavailable frequency sets;
• and
• means for determining an overall scheduling metric score for each device, the scheduling metric score is a product of the fairness metric and one or both of the overall channel peak desirability metric and the channel delay desirability metric.

A computer-readable medium having stored thereon computer-executable instructions for:

• determining a fairness metric for each user device in a wireless network environment;
• determining an overall channel peak desirability metric for each user device, wherein the overall channel peak desirability metric reflects the instant channel desirability on the user device's best available frequency set relative to the user device's average channel quality;
• and
• determining a channel delay desirability metric for each user device, wherein the channel delay desirability metric is the ratio between the maximum instant spectral efficiency over all free frequency sets, and the maximum instant spectral efficiency over all unavailable frequency sets.

A microprocessor that executes instructions for dynamic frequency set scheduling in a wireless communication network region, the instructions comprising:

• assessing each of a fairness metric, an overall channel peak desirability metric, and a channel delay desirability metric for each of a plurality of user devices in the network region, wherein the channel delay desirability metric is the ratio between the maximum instant spectral efficiency over all free frequency sets and the maximum instant spectral efficiency over all unavailable frequency sets;
• determining an overall scheduling metric score for each user device that is based on the fairness metric and at least one of the overall channel peak desirability metric and the channel delay desirability metric;
• and
• awarding a frequency set to a user device with a highest overall scheduling metric relative to the other user devices in the network region.
