Determining “fair share” of radio resources in radio access system with contention-based spectrum sharing

摘要

A method, apparatus, system, and computer program product example embodiments of the invention are disclosed to structure access to a wireless medium to reduce interference between nearby nodes. In example embodiments of the invention, a method includes the steps of determining an amount of available wireless communication resources in a reception area; determining a number of wireless communication nodes in the reception area; generating a reservation limit of the available wireless resources; determining an inability to allocate the reservation limit of the available wireless resources; transmitting a request for release of resources to at least one other wireless communication node. Another node receiving the request, performs a method including the steps of determining a threshold; comparing an allocated amount of wireless communication resources against the threshold; and releasing at least a part of the allocated amount of resources, if the reserved number is greater than the threshold.

主权项

1. A method comprising:
determining an amount of available wireless communication resources in a reception area; determining a number of wireless communication nodes in the reception area; generating a reservation limit of the available wireless communication resources; determining an inability to allocate the reservation limit of the available wireless communication resources; transmitting a request for release of resources to at least one other wireless communication node, the request for release including an indication of the reservation limit; attempting to allocate available wireless communication resources, resources that have been released by at least one other wireless node based on the reservation limit, and temporarily limiting the number of allocated resources to the reservation limit; and transmitting a release message to the at least one other wireless communication node, to enable at least one other wireless communication node to attempt to re-allocate resources that it released in response to the request for release of resources.
