摘要： A method of throughput and data volume measurement for minimization of drive test (MDT) is proposed. A base station establishes a radio resource control (RRC) connection with a user equipment (UE) in a mobile communication network. The base station or UE measures transmitted or received data volume during a transmission time of a data burst between the base station and the UE. When the data burst spans multiple measurement periods and the data burst is split at each measurement period boundary. For each measurement period, data volume during the measurement period is measured to generate a measurement result. When throughput measurement is performed by the network, the base station receives location information that is available during the transmission time of the data burst. The data volume measurement is logged with time stamp such that each measurement result can correlated with the location information.

摘要： A method of UE RSRQ measurement precaution for interference coordination is provided. The UE receives radio signals of a neighbor cell under measurement. The neighbor cell applies a TDM silencing pattern for inter-cell interference coordination (TDM ICIC). The UE determines a measurement pattern that includes multiple subframes. The UE performs RSRQ measurements of the cell over multiple subframes and obtains multiple RSRQ measurement samples. The UE derives RSRQ measurement result by estimating the multiple RSRQ samples and applying a weighted average. RSRQ samples estimated to be more applicable are taken into account to more extent (e.g., applied with more weight), and/or RSRQ samples estimated to be less applicable are taken into account to less extent (e.g., applied with less weight, or discarded with zero weight). With UE precaution, a more predictable RSRQ measurement result is produced.

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 inter-cell interference coordination is provided for UE measurements and network access procedure.In a first embodiment, a UE in idle mode performs measurements on received radio signals applying a simplified radio resource restriction for interference coordination. The UE determines the restricted radio resource without receiving explicit measurement configuration. In a second embodiment, during various phases of a network access procedure, the UE indicates its interference status and/or additional interference information to its serving base station to enhance interference coordination. In a third embodiment, the UE in connected mode performs measurements on both interference-protected transmission resources and non-interference-protected transmission resources. The UE measurement results are used for scheduling, radio link monitoring, and/or mobility management to increase radio spectrum efficiency and to improve user experience.

摘要： Methods for enhanced heterogeneous network mobility are proposed. In a first novel aspect, the cell size of a target cell is considered when determining the TTT value. In one embodiment, pico-specific Time-to-Trigger (TTT) value is configured. When the target cell to be measured is a picocell, pico-specific TTT value is applied. In a second novel aspect, precise mobility state estimation (MSE) is achieved by considering the effect of cell size. In one embodiment, when counting cell changes, a cell change to/from a small cell would be counted to lesser extent than a cell change between large cells. UE uses effective parameters for measurement evaluation, by applying better speed state estimation with speed scaling and by applying parameter differentiation that can be dependent on cell size.

摘要： Methods for small cell discovery in heterogeneous networks are proposed for efficient cell search and better power saving. In one novel aspect, a user equipment (UE) measures small cells only when the UE enters into the vicinity of the small cells. For example, the UE detects the proximity of small cells and reports proximity indication information to the network. Based on the vicinity indication, the network provides suitable measurement configuration for small cells. In a second novel aspect, the UE performs guided search for small cell discovery. In a third novel aspect, the UE increases search rate for small cells when it is in the vicinity of small cells, and decreases search rate for small cells when it is not in the vicinity of small cells. The detection may be based on location information provided by the network or based on vicinity detection information autonomously stored by the UE.

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.
