Description

小区发现方法和装置
技术领域
本发明涉及移动通信领域, 尤其涉及一种小区发现方法和装置。 背景技术
随着无线多媒体业务的发展, 人们对高数据速率和用户体验的需求日益 增长, 从而对传统蜂窝网络的系统容量和覆盖提出了较高要求。 在传统 LTE 蜂窝网络中, 宏基站作为唯一的接入侧网元为 UE提供接入服务。 而为了满 足用户对较高数据速率的需求并提高蜂窝网络频谱效率, 3GPP 引入了低功 率节点 (LPN )作为宏基站的补充为 UE提供接入服务。 LPN具有低成本, 低功率, 方便部署等特点, 通常有热点部署和增强覆盖两种部署场景, 能有 效的提高室内或室外热点区域高速率数据业务的数据速率, 改善边远地区或 小区边缘覆盖。 通常 LPN也可称为小基站, 包括家庭基站(HeNB ) , 微微 基站(pico ) , 射频拉远单元 /头 (RRU/RRH ) , 中继节点 (RN )等。 而小 基站下的小区通常称为小小区 ( small cell ) 。
为了使 UE获得更高的数据速率和减少 UE耗电,需要 UE能及时有效的 发现附近的小基站节点, 以便于网络节点能及时将 UE分流至附近的小基站 以获得高数据速率, 并同时分流宏基站负荷, 并且不同地理区域的小基站可 以复用相同频语资源, 以较大提高频谱效率。 另一方面, UE 的耗电也是用 户最为关心的问题。 UE 分流至小基站后由距离较近的小基站服务, 能很好 的节省 UE的耗电。 另夕卜, UE的电量消耗 4艮大一部分还体现在对相邻小区的 发现及测量上。 特别是小基站与宏基站釆用不同的频点情况下需执行异频测 量以完成小区发现。 LTE中 UE执行异频测量需由基站为 UE配置测量间隙, 在测量间隙期间 UE与服务基站通信中断以测量异频小区。 而 UE可同时测 量的异频载频有限, 若需要测量的异频数量较多, 则为 UE配置更多的测量 间隙, UE执行异频测量需消耗的电量也越多。 另外, LTE中针对连接态 UE 可釆用 s-measure机制控制 UE开启 /关闭包括异频测量在内的对相邻小区的 测量行为。 基站可为 UE配置 s-measure值(也即服务小区 RSRP门限值 ) , 若 UE的服务小区 RSRP值高于门限值, 则不需要开启对相邻小区的测量。 在热点部署场景下, 为了达到较高的数据速率和频谱效率, 需要在区域 内密集大量部署小基站, 并且宏基站与小基站有可能釆用不同频点, 小基站 之间也有可能釆用不同频点。 特别的, 在室内部署场景, 如办公室, 商场等 通常为多楼层建筑, 不同楼层均可能有小基站部署, 而不同楼层的小基站工 作载频可能并不相同, 也即进入该区域的 UE为了发现相邻的小小区需针对 大量的异频频点执行异频测量, 进而造成大量的 UE耗电。
并且在热点部署场景下, 小基站有可能靠近宏基站部署, 即位于宏基站 小区中心区域, 而不是部署于宏基站小区边缘。 釆用 s-measure机制情况下, 由宏小区服务的 UE位于宏小区中心区域的小小区范围内时测量得到的服务 小区 RSRP值仍然较好,且有很大可能高于 s-measure值,导致不能及时触发 开启对相邻小区的测量, 进而不能有效的发现附近的小小区。 釆用相关 s-measure机制并不适用于小基站热点区域部署下的小小区发现。
