摘要： A method of dynamic resource transaction in wireless OFDMA systems is proposed. In macro-femto overlay network architecture, network and traffic condition varies dynamically. Dynamic resource transaction is a powerful mechanism to achieve effective interference mitigation and flexible radio resource management to enhance resource utilization as well as to improve link performance. Dynamic resource transaction can be performed by signaling or message exchange through backhaul network or air-interface connections. The signal or message through backhaul network can be directly exchanged among multiple base stations or be routed through a centralized self-organizing network (SON) server. In one embodiment, dynamic resource transaction is used to achieve adaptive reservation region configuration, a solution to avoid interference and frequent handover for highspeed mobile stations.

摘要： An adaptive RACH operation is proposed for machine-type communications (MTC) in a 3GPP wireless network. The adaptive RACH operation is based on context information to reduce RACH collision probability, to control network overload, and to enhance system performance. The context information includes device related information and network related information. Device related information includes device type and service or application type. Network related information includes network load information and historical statistics information. Based on the context information, an MTC device adjusts various network access and RACH parameters by applying adaptive RACH operation in different levels. For example, in the application level and the network level, the MTC device adjusts its access probability or RACH backoff time for RACH access. In the radio access network (RAN) level, the MTC device adjusts its access probability or RACH backoff time, or transmits RACH preambles using adjusted RACH radio resources and preambles.

摘要： A Femto Base Station (FBS) includes a communication functionality and a reliability functionality. A control entity within the reliability functionality detects an FBS reliability compromising event (for example, an unscheduled loss of external power to the FBS). As a result of detecting the FBS reliability compromising event, the control entity sends a message (an "FBS Reliability Compromising Event Compensation Message" or "FBSRCECM") to the communication functionality. The FBSRCECM initiates an action that compensates for the FBS reliability compromising event. In many examples, the action is the initiating of a handover from the FBS to another base station. The reliability functionality typically includes a rechargeable battery that powers the FBS for a time until the handover is completed gracefully. By performing a graceful handover, cellular network reliability is improved as compared to situations in which a conventional FBS simply stops working and connections handled by the conventional FBS are broken.
摘要翻译：毫微微基站（FBS）包括通信功能和可靠性功能。可靠性功能内的控制实体检测到FBS可靠性损害事件（例如，对FBS的外部功率的非计划丢失）。作为检测FBS可靠性破坏事件的结果，控制实体向通信功能发送消息（“FBS可靠性妥协事件补偿消息”或“FBSRCECM”）。 FBSRCECM启动一项补偿FBS可靠性破坏事件的动作。在许多示例中，动作是发起从FBS到另一个基站的切换。可靠性功能通常包括为FBS供电一段时间的可充电电池，直到切换顺利完成。通过执行优雅的切换，与常规FBS简单停止工作并且由传统FBS处理的连接断开的情况相比，提高了蜂窝网络的可靠性。

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.

摘要： Methods to manage multiple component carriers (CCs) efficiently in a mobile network with carrier aggregation (CA) enabled are proposed. For CC activation/deactivation, a single LCID value is used to represent both activation and deactivation command. A single command with multiple instructions is provided to activate and/or deactivate multiple CCs. In addition, unnecessary re-activation or re-inactivation of a CC is prevented, and explicit feedback for activation/deactivation is considered. For scheduling mechanism, a novel buffer status reporting (BSR) procedure is provided, where only one BSR is calculated after preparing all the transport blocks (TB) within one transmission time interval (TTI). Novel power headroom reporting (PHR) format and trigger are also provided. For DL-UL linking, various linking types are created based on whether there is carrier indicator field (CIF) in DL grant or UL grant. The various linking types are used in different applications to improve scheduling flexibility and load balancing.

摘要： A method of implicit signaling to support In-Device coexistence interference avoidance is provided. A UE sends an IDC interference indication to an eNB. The indication indicates that a serving frequency becomes unusable due to a coexistence interference problem. The indication does not explicitly indicate a frequency index or a frequency location of the unusable serving frequency. The eNB determines the serving frequency as unusable in an implicit manner. The eNB also determines an implied unusable frequency region based on the received IDC indication. The implied unusable frequency region is between the serving frequency and the ISM band. In one advantageous aspect, the eNB configures a condition for the UE, such that the UE is refrained from sending IDC interference indications unless the condition is satisfied.
摘要翻译：提供了一种支持In-Device共存干扰避免的隐式信令的方法。 UE向eNB发送IDC干扰指示。该指示表示由于共存干扰问题，服务频率变得不可用。该指示没有明确地指示不可用的服务频率的频率索引或频率位置。 eNB将服务频率以隐含的方式确定为不可用。 eNB还基于接收的IDC指示确定隐含的不可用频率区域。隐含的不可用频率区域在服务频率和ISM频带之间。在一个有利的方面，eNB配置UE的条件，使得除非满足条件，否则UE不会发送IDC干扰指示。

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： A method of providing Local IP Access (LIPA) indication is proposed. In one novel aspect, an enhanced cell selection method is proposed using LIPA capability information. Based on LIPA capability related information, a UE is able to prioritize LIPA-capable cells and establish a corresponding packet data network (PDN) connection accordingly. In one embodiment, LIPA information is informed to the UE via Non Access Stratum (NAS) signaling. The UE stores LIPA capability information when receiving a NAS message from a mobility management entity (MME). Later on, when the UE performs cell selection or reselection in idle mode, the UE can use the stored LIPA capability information to prioritize LIPA-capable cells.

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.
