摘要
小区初搜是指终端开机到驻留到一个小区的过程,其性能直接影响到UE进行后续的过程。鉴于常规的带BA表的UE小区初搜过程的效率不高,提出了一种利用相关的算法加快带BA表的UE小区初搜过程,仿真结果表明该方案能够缩短UE进行小区初搜的时间以及降低UE在错误频点上进行小区初搜的概率,从而提高了小区初搜效率。
Initial Cell Search is a process that User Equipment boots to reside to a cell. Its performance has a direct impact on the follow-up process of UE. In the view of conventional initial cell search, which UE has a BA table, the efficiency is low. A correlation algorithm is used to speed up the UE cell search with a BA table o The simulation results show that this scheme can reduce the UE time for initial cell and decrease the probability of error fre- quency points in the initial cell search, thereby improve the initial cell search efficiency.
