Summary:
Cell outage is the total loss of radio services in the coverage area of a cell. Aiming at mitigating the coverage problems caused by a sudden outage, this paper proposed a concrete cell outage compensation scheme based on immune algorithm. Taking into account the two objectives, coverage and quality, the scheme constructs a mathematical model which adjusts the uplink target received power in surrounding cells, and generates a specific solution by adopting immune algorithm. The reported simulation results show that the proposed algorithm is able to recover a large proportion of unserved users and mitigate the performance degradation.
