Abstract
A method and apparatus for transmission in a trunked radio communication system comprises a first mobile radio subscriber unit receiving identity data from one or more other mobile radio subscriber units. The first mobile radio subscriber unit detects the distance from the first mobile radio subscriber unit to each of the one or more other mobile radio subscriber units. This information is transmitted to the infrastructure of the system, which selects a communication channel for the first mobile radio subscriber unit, so as to reduce close proximity interference between the mobile radio subscriber units. The mobile radio subscriber units may check for blocking conditions prior to initiating communication, and when necessary may delay transmission. The check may be based on information received via Bluetooth from other mobile radio subscriber units, and Bluetooth signal strength information.
