1. A method of reducing a time delay between an application output at a subscriber station and uplink resource allocation for the subscriber station, comprising:
- scheduling, between periodic uplink resource allocations, one or more probe uplink resource allocations for the subscriber station;
receiving, at an access point, respective information in at least one of the one or more probe uplink resource allocations and wherein the respective information corresponding to respective reported queue sizes of a queue of the subscriber station at different times; and
adjusting a period of a subsequent periodic uplink resource allocation based on receiving information in the at least one of the one or more probe uplink resource allocations wherein adjusting the period of subsequent periodic uplink resource allocations being based on the respective queue sizes to substantially minimize an average size of the queue.

Abstract
A technique for reducing a time delay between an application output at a subscriber station and uplink resource allocation for the subscriber station includes scheduling, between periodic uplink resource allocations, one or more probe uplink resource allocations for the subscriber station. Next, respective information in at least one of the one or more probe uplink resource allocations is received at an access point. Finally, subsequent periodic uplink resource allocations are scheduled based on at least one of the one or more probe uplink resource allocations.
