Recognition and utilization of auxiliary error control transmissions

摘要

A method and apparatus for determining if useful auxiliary information in an auxiliary time slot is available for subscriber unit use. The present invention includes a receiver that receives data from both an auxiliary time slot and a dedicated time slot. Data from the receiver is coupled to a computation function that calculates a metric comparing the data from the auxiliary time slot and the dedicated time slot. The calculated metric is coupled to a threshold comparator that compares the calculated metric to a threshold. Based on the results of the comparison, a determination is made on the presence or absence of useful auxiliary data in an auxiliary time slot.
