Solving exposed terminal problems in wireless networks

摘要

Methods, apparatus and program products are disclosed for allowing wireless devices in two wireless access networks whose coverage areas overlap to communicate with their respective access nodes. Groups may be assigned to wireless devices in the access networks and the groups may be used by wireless devices in the access networks to determine whether to access a communication medium or not. Received powers may also be used by wireless devices in the access networks to determine whether or not to access a communication medium. A wireless device in a first access network can determine whether to access (e.g., compete for access to) the communication medium by comparing a measured power of transmission from a second access node with an indication of a minimum received power above which wireless devices in a second access network formed by a second access node are allowed to contend for access to the communication medium.
