Problems solved by technology

The impact of such inter-network interference on radio link quality may not be negligible, and becomes more serious when a large number of TD moves across different UDN overlapping regions belonging to different operators

Abstract

Methods and apparatuses for coordinating resource scheduling between wireless networks are provided. The method comprises receiving a resource coordination request message from at least one wireless network, wherein the resource coordination request message includes identifiers of at least one pair of wireless links which include an interfered wireless link in the at least one wireless network and an interfering wireless link in a second wireless network. The method also comprises performing coordination about schedulable resources for the interfered wireless link and the interfering wireless link based on the resource coordination request message. The method further comprises transmitting a coordinated schedulable resource message to the at least one wireless network and the second wireless network such that at least one of the interfered wireless link and the interfering wireless link is scheduled according to the coordinated schedulable resource message. With the methods and apparatuses of the present disclosure, the interference taking place between wireless networks can be avoided or at least reduced by coordinating resource scheduling.

Description

technical field [0001] The disclosed non-limiting and exemplary embodiments of the present invention relate to the field of wireless communications. In particular, embodiments of the invention relate to methods and apparatus for coordinated resource scheduling between two or more networks operating on the same or overlapping radio resources. Background technique [0002] With the rapid development of wireless communication technology and increasing traffic demands, a new network architecture is proposed, also known as ultra-dense network (“UDN”). UDN is mainly expected to be deployed in the form of "covered islands", serving relatively small areas (such as office buildings, shopping malls, etc.). In general, a specific area will be served by only one UDN, i.e., while possible, parallel deployment of multiple UDNs is considered impossible. Adjacent or spatially separated UDN deployments are expected to have relatively good isolation due to the high wave propagation loss. T...
