摘要： The invention provides methods, a network device and radio station for spectrum resource allocation in a network employing spectrum sharing among at least a primary and secondary system, including scanning, by a network device of the secondary system, a specific frequency range of a candidate band of the primary system, estimating, by the network device, interference level on the scanned candidate band of the primary system, determining position of the network device, and transmitting the estimation result to a radio station of the secondary system.

摘要： A method, apparatus, and computer program for continuing transmission during handover are presented. A communication connection is established between a source base station and a mobile relay base station comprising a distributed antenna system (DAS). The DAS includes multiple spatially distributed antenna units (DAUs), wherein at least part of the DAUs are used for forming a cluster of sub-cells within a coverage area of the mobile relay base station and at least part of the DAUs are used for communicating with a fixed cellular network infrastructure over multiple backhaul links. A first backhaul link is then handed over from the source base station to a target base station. After the handover, data transfer between the source base station and at least one backhaul link still linked to the source base station is continued, and remaining backhaul link(s) are released from the source base station according to a determined criterion.
