UE频间测量控制命令触发的测量报告；l UE内部测量控制命令触发的测量报告；l Inter-RAT测量控制命令触发的测量报告；l 业务量测量控制命令触发的测量报告；l UE质量测量控制命令触发的测量报告；讨论UE测量报告。UE测量控制的相关背景参见UE测量控制过程研究报告。本文研究UE测量报告，用于对UE的测量报告库的维护、指导RRM V2开发，并供后续研究参考。对于V2实现，本文档作如下假设：l 只考虑1.28 Mcps TDD的情况；l 目前Node B带GPS接收机，暂不支持小区同步过程；l 不考虑与FDD模式和3.84Mcps TDD的兼容性；l 不支持上下行共享信道；l 不采用分层小区结构（HCS）；l 不支持系统间测量（Inter-RAT）及定位测量；1.2预期读者和阅读建议本文档适合RRM项目组成员、项目经理、系统测试人员。1.3文档约定a)

on RACH测量准则上报：MEASUREMENT REPORT除了这两个IE上报测量结果；还有下列消息可上报测量值：PUSCH CAPACITY REQUEST如果在CELL_FACH状态下一个正在进行的业务量测量满足报告准则，并且与其MEASUREMENT_IDENTITY相关的RB是映射在USCH传输信道上，则UE将在SHCCH发送"PUSCH CAPACITY REQUEST"（包含测量结果），而不是在上行DCCH发送"MEASUREMENT REPORT"。上报内容取决于消息PHYSICAL SHARED CHANNEL ALLOCATION中设置。第二阶段不使用共享信道，故在此不予分析。UE直接上报测量结果时又分为周期上报、事件上报（见附录1）。l 测量报告消息处理流程a) 根据报告消息使用的物理信道找到对应的UE ID；根据UE ID判断其当前服务小区Id。b) 根据Measurement ID判断报告值对应的报告类型及测量类型：事件上报时，则UE同时需要上报相应的Event results。周期上报时，则UE只需要上报测量结果。在此参考附录2的UE Measurement ID映射表。c) 利用下列信息在当前服务小区Id对应的报告库中搜索测量值存储位置：l 频内测量：【Cell parameters Id】l 频间测量:【频率ID, Cell parameters Id】l 业务量测量：【RB ID】l 质量测量：【传输信道ID】l UE内部测量：【报告量】UE具体报告量见附录4。d) 在相应位置存储此测量报告值。周期上报时，只需要将测量值存储在报告库中；事件上报时，先将测量值与触发事件发给被触发的RRM算法，然后将测量值存储在报告库中。下面将具体描述测量上报特性。2.1 附加上报（Measured Results on RACH）附加上报是利用IE"Measured results on RACH"上报测量结果。此上报方式相当于NodeB侧测量的立即上报（On Demand）。SIB11/12中的IE"Intra-frequency reporting quantity for RACH Reporting"与IE "Maximum number of reported cells on RACH "对IE"Measured results on RACH"如何上报哪些测量量进行了具体设置。此IE上报的测量值不进行L3滤波。UE可上报IE"Measured results on RACH"的消息如下： CELL UPDATE：小区更新采用: CCCH（RLC-SAP: TM） INITIAL DIRECT TRANSFER：采用: DCCH（RLC-SAP: AM） MEASUREMENT REPORT：报告准则满足时采用: DCCH（RLC-SAP: AM or UM） RRC CONNECTION REQUEST：用户连接请求时采用: CCCH（RLC-SAP: TM） UPLINK DIRECT TRANSFER：采用: DCCH（RLC-SAP: AM）以上消息什么条件下可上报IE"Measured results on RACH"？上报必须满足条件：包含测量结果的消息长度不能超过最大允许消息长度。INITIAL DIRECT TRANSFER，CELL UPDATE，UPLINK DIRECT TRANSFER三个消息只能上报CELL_FACH状态下的测量值。RRC CONNECTION REQUEST只能上报空闲模式的测量值。MEASUREMENT REPORT在CELL_FACH状态下只能在报告业务量（traffic volume）测量或UE定位测量结果时上报此IE对应的测量值。测量结果上报列表应该按照测量量的大小排序（第一个小区为最佳小区）。测量量设为"RSCP"的最佳小区为测量值最大的小区；而测量量设为" Pathloss "的最佳小区为测量值最小的小区。2.2 直接上报（MEASUREMENT REPORT）UE直接上报测量结果的消息为MEASUREMENT REPORT。此报告方式基于测量报告准则。MEASUREMENT REPORT结构如下：Information Element/Group nameNeedMultiType and reference参数说明Message TypeMPMessage TypeUE information elementsIntegrity
