发明名称 METHOD AND NETWORK NODE FOR SUPPORTING COMPENSATION OF CELL OUTAGE IN A CELLULAR COMMUNICATIONS NETWORK
摘要 A method in, and a network node (110, 140), for supporting compensation of cell outage in a cellular communications network (100). The cellular communications network (100) comprises a compensating cell (135) for compensating the cell outage and a supporting cell (115) neighbouring the compensating cell (135). The network node (110, 140) obtains (502, 1202) a sub-band of a system bandwidth for uplink scheduling of resources for the compensating cell (135). The network node (110, 140) schedules (503, 1203), in response to the cell outage, resources for the supporting cell (115) with restricted uplink scheduling within the sub-band. The network node applies (504, 1204) the scheduled resources in the supporting cell (115), thereby supporting the compensation of cell outage. As a result, higher Signal to Interference and Noise Ratio (SINR) is enabled in the uplink in the compensating cell. This may e.g. be utilized to let the compensating cell cover a larger area of an outage cell than else would be possible, and/or to serve user equipments located therein with improved performance.
