Abstract: A method and an apparatus for managing Sounding Reference Signal (SRS) resources in a wireless communication system are provided. A method of a base station for managing SRS resources includes receiving an allocation of SRS resources from a system controller, allocating SRS resources to connected terminals that are connected to the BS, determining a number of residual SRS resources varying according to the number of connected terminals, and transmitting one of an additional SRS resource allocation request and an allocated SRS resource return request to the system controller according to the number of residual SRS resources.

Abstract: Disclosed are a method and an apparatus for detecting a cell outage and controlling transmission power. The method of detecting the cell outage includes: receiving a Radio Link Failure (RLF) message from a User Equipment (UE) or an adjacent BS; acquiring Reference Signal Received Power (RSRP) and Reference Signal Received Quality (RSRQ) of the UE with respect to a serving cell and adjacent cells before RLF generation, which are included in the RLF message; calculating a Signal to Interference plus Noise Ratio (SINR) of the serving cell by using the acquired RSRP and RSRQ; calculating an SINR of a best adjacent cell having a largest RSRP among the adjacent cells of the UE by using the acquired RSRP and RSRQ; and comparing an SINR of a best cell having a largest SINR between the serving cell and the best adjacent cell with a preset reference value and determining whether the cell outage has been generated.
