RADIO ACCESS NETWORK SHARING

摘要

The present invention relates to wireless systems, and in particular provides a method of sharing radio resources between a first cell of a first cellular network and a second cell of a second cellular network. Each cell transmits using a respective carrier of a different frequency and each cell uses a respective scheduler to allocate transmissions to a respective plurality of radio resources. The method comprises identifying a transmission for a user attached to the first cell that is available for radio resource allocation by the scheduler of the first cell, where the transmission could be made over the second carrier; and interfacing between the scheduler of the first cell and the scheduler of the second cell, so as to allocate radio resources for use by the second cell to the transmission for the user attached to the first cell.
