Claim Text:
1. 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; obtaining a Low Interference Bandwidth Center (LIBC) to be comprised in the sub-band; scheduling, in response to the cell outage, resources for the supporting cell with restricted uplink scheduling within the sub-band, wherein scheduling the resources for the supporting cell comprises selecting resources from one or both ends of the system bandwidth of the supporting cell and gradually towards the LIBC, thereby obtaining the sub-band as a bandwidth adjoining the LIBC and with the restricted uplink scheduling within the sub-band; and applying the scheduled resources in the supporting cell, thereby supporting the compensation of the cell outage by causing less interference within the sub-band in the compensating cell.
