Abstract
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.

39. A method in a network node for supporting compensation of cell outage in a cellular communications network, the cellular communications network comprising a compensating cell for compensating the cell outage and a supporting cell neighboring the compensating cell, wherein the method comprises:
-
obtaining a sub-band of a system bandwidth for uplink scheduling of resources for the compensating cell; scheduling, in response to the cell outage, resources for the supporting cell with restricted uplink scheduling within the sub-band; and applying the scheduled resources in the supporting cell, thereby supporting the compensation of cell outage by causing less interference within the sub-band in the compensating cell. - View Dependent Claims (40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57)
