Abstract:

 For cell outage problem due to various faults in wireless access networks，an distributed time division-synchronous code division multiple access (TD-SCDMA) high load cell outage compensation algorithm is presented based on uplink target receiving power adjustment in open loop power control. In the presented algorithm, the parameters of cells neighboring failed cells can be automatically adjusted such that the coverage is maximized the given constrains on quality defined by cell-edge user throughput. Simulation shows that up to 78% of the user can be recovered at the cost of an acceptably reduced quality in the compensating cells.

Key words:  cell outage compensation, uplink target receive power, power control iteration, time division-synchronous code division multiple access
