LTE-A中一种小区无线网络临时标识的分配方案

An allocation scheme of cell-radio network temporary identifier in LTE-A

LTE-A系统中,在为UE分配C-RNTI时,必须同时满足具有载波聚合能力的UE在主小区和辅小区使用相同的C-RNTI以及单个小区服务一定数量的UE这两个要求。针对这一需求,结合目前常用的静态预留法,在此基础上提出了一种改进型方案,通过预先为UE主小区和辅小区设置C-RNTI共享数据段并为此C-RNTI共享数据段内的每个C-RNTI增加相应的标识信息的方法,以期实现对LTE-A系统中C-RNTI的分配。

The Cell-Radio Network Temporary Identifier （C-RNTI） is allocated to UE in LTE-advanced（LTE-A） system must also meet with carrier aggregation ability of UE in primary cell and secondary cell using the same C-RNTI and single cell service a certain number of UE.In response to this demand, and combined with the static reservation method which is commonly used, an improved method is proposed in this paper so that the allocation of C-RNTI in LTE-A system was realized by pre-setting primary cell and secondary cell sharing C-RNTI data segment and increasing some marked information for sharing C-RNTI data segment of carrier aggregation cell.
