摘要： A method of managing access to problem event information collected by a User Equipment (UE). In one novel aspect, access to the problem event information is determined by a public land mobile network (PLMN) list stored in the UE. The UE collects problem event information, stores a PLMN list, and sends an indication that problem event information is available to a Radio Access Network (RAN) controller. In response, the RAN controller sends a request indicator to the UE requesting the event information. The UE transmits the requested event information when the requesting PLMN is included in the PLMN list stored in the UE. In one embodiment, the event information includes Minimization Drive Test (MDT) measurement information. In another embodiment, the event information includes radio link failure information. The solution enables managing access to problem event information with maximum simplicity and minimum impact to existing systems.

摘要： A method of radio link monitoring (RLM) and radio link failure (RLF) handling over a secondary serving cell (SCELL) is proposed. In a wireless network, a user equipment (UE) establishes a radio resource control (RRC) connection with a base station (eNB). The UE applies carrier aggregation for multiple component carriers (CCs) configured as multiple serving cells. The UE performs radio link monitoring over a primary serving cell (PCELL). The UE also performs radio link monitoring over a secondary serving cell (SCELL). The SCELL belongs to a CC group of one or more CCs, and used as a reference cell for the CC group. When SCELL performance is below pre-defined criteria, the UE and the eNB apply certain actions over the SCELL or all CCs in the CC group. The proposed SCELL RLM/RLF handling prevents spurious and uncontrollable uplink SCELL transmission and interference to other UEs.
摘要翻译：提出了一种在辅助服务小区（SCELL）上的无线电链路监测（RLM）和无线电链路故障（RLF）处理的方法。在无线网络中，用户设备（UE）建立与基站（eNB）的无线资源控制（RRC）连接。 UE为配置为多个服务小区的多个分量载波（CC）应用载波聚合。 UE在主服务小区（PCELL）上执行无线电链路监视。 UE还在辅助服务小区（SCELL）上执行无线电链路监视。 SCELL属于一个或多个CC的CC组，用作CC组的参考细胞。当SCELL性能低于预先定义的标准时，UE和eNB通过SCELL或CC组中的所有CC应用某些动作。所提出的SCELL RLM / RLF处理可防止对其他UE发生杂散和不可控的上行SCELL传输和干扰。

摘要： A method of managing multiple timing advance (TA) groups, maintaining multiple TA timers, and performing UL synchronization in a multi-carrier wireless system is provided. When a new component carrier (CC) is configured, it is assigned to a TA group having a TA group identifier. The TA groups are managed statically or dynamically. The TA group identifier is used to uniquely identify the TA group in the operations of uplink (UL) timing synchronization. Multiple TA timers are assigned to multiple TA groups. The TA timers may have different values for different TA group. Different embodiments of UL timing adjustments for multiple TA groups are provided.

摘要： A method of failure event report correlation is proposed. A UE detects a failure event in a first cell served by a first base station, and the UE is assigned with a previous C-RNTI. The failure event may include a radio link failure, a handover failure, or a RACH failure. The UE then performs an RRC establishment procedure with a second base, and the UE is assigned with a new C-RNTI. After the RRC establishment, the UE transmits a failure event report along with the correlation information to the second base station. The second base station then forwards the failure event report and the previous C-RNTI to the first base station. The first base station can correlate the failure event report with the previous failure event based on the previous C-RNTI to avoid double bookkeeping and improve MRO decision for SON.
摘要翻译：提出了一种故障事件报告相关的方法。 UE检测由第一基站服务的第一小区中的故障事件，并且向UE分配先前的C-RNTI。故障事件可能包括无线电链路故障，切换故障或RACH故障。然后，UE执行具有第二基站的RRC建立过程，并且向UE分配新的C-RNTI。在RRC建立之后，UE将故障事件报告与相关信息一起发送到第二基站。第二基站然后将故障事件报告和先前的C-RNTI转发到第一基站。第一个基站可以根据先前的C-RNTI将故障事件报告与先前的故障事件相关联，以避免双重记录，并改善SON的MRO决策。

摘要： A method of measurement gap reporting and configuration is provided. In a mobile network, a UE receives a capability enquiry message from a serving base station. The UE comprises one or more radio frequency modules that support a list of frequency bands and a list of carrier aggregation (CA) band combinations. In response to the enquiry, the UE transmits capability information containing measurement parameters to the base station. In one embodiment, the measurement parameters comprise need-for-gap parameters for each frequency band and each CA band combinations associated with a list of to-be-measured frequency bands of target cells. Based on the reported measurement parameters, the eNB transmits a measurement configuration message to the UE. Finally, the UE transmits a measurement gap application message back to the base station. The measurement gap application message indicates whether the UE applies MG for each configured component carrier.
