Abstract

A method of wireless communication includes determining denial rates for first and second communication attempts of a packet using a first communication resource (e.g., an LTE radio). The method also includes allowing a second communication resource (e.g., a Bluetooth radio) to communicate when communication attempts from the first communication resource are denied. The denial rates are chosen to achieve threshold levels of performance for the first and second communication resources. The second denial rate may be set and the first denial rate adjusted in a looped manner to achieve desired Bluetooth performance. The denial rates may be set to deny all first communication attempts but to allow all second communication attempts. Final attempts to transmit Bluetooth packets may be given priority regardless of the first and second denial rates.
