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： A power control method to mitigate in-device coexistence (IDC) interference is provided. A wireless communication device (UE) is equipped with a first LTE radio module and a second co-located WiFi/BT/GSNN radio module. Upon detecting coexistence or IDC interference, the UE applies power control method to mitigate the interference. In a first embodiment, the LTE radio module adjusts its power parameters locally without informing the serving eNB. In a second embodiment, the LTE radio module adjusts its power parameters and implicit informs the eNB through existing PHR reporting. In a third embodiment, the LTE radio module changes its power or power class and explicitly informs the eNB through UE capability or new RRC message or MAC CE. Power control can be used as a low cost and lightweight solution before applying other heavyweight solutions that either require more resource or control overhead, or have higher impact on throughput.

摘要： Various methods for wireless communication in a device with co-existed/co-located radios are provided. Multiple communication radio transceivers are co-existed/co-located in a user equipment (UE) having in-device coexistence (IDC) capability, which may result in IDC interference. For example, the UE is equipped with both LTE radio and some ISM band applications such as Wi Fi and Bluetooth modules. In a first method, the network identifies IDC capability by UE identification (e.g., UE ID). In a second method, the UE intentionally performs cell selection or reselection to cells in non-ISM frequency bands. In a third method, the UE signals the existence of ISM band applications via capability negotiation. In a fourth method, the UE signals the activation of ISM band applications by signaling messages (e.g., RRC message or MAC CE). Under the various methods, the UE and its serving eNB can apply FDM or TDM solutions to mitigate the IDC interference.

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 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.
