Flexible spectrum sharing

摘要

Various example embodiments are disclosed. According to one example embodiment, a method may include receiving, by a first wireless node in a first wireless network, a request from a second wireless node in a second wireless network to borrow spectral resources from the first wireless network. The method may further include determining a cost of granting the request, the cost being based at least in part on a cost to a lending cell within the first wireless network from which the spectral resources will be borrowed and a cost to neighboring cells of the lending cell. The method may further include lending the spectral resources to the second wireless node based at least in part on the determined cost of granting the request.

主权项

1. An apparatus comprising: a controller; the apparatus being configured to:
receive, by a first wireless node in a first wireless network, a request from a second wireless node in a second wireless network to borrow spectral resources from the first wireless network; determine a cost of granting the request, the cost being based at least in part on: a cost to a lending cell within the first wireless network from which the spectral resources will be borrowed; and a cost to neighboring cells of the lending cell; and lend the spectral resources to the second wireless node based at least in part on comparing the determined cost of granting the request to a gain, the gain being based on an offered payment, wherein the determined cost depends at least on a current or predicted load of the lending cell and of the neighboring cells of the lending cell.
