Abstract: Aspects of the disclosure provide a method that includes receiving a measurement configuration message indicating a predetermined number. A measurement event is defined based on the predetermined number of signal beams from a serving base station and the predetermined number of signal beams from a neighboring base station. The method also includes identifying a first number of best signal beams from the serving base station and a second number of best signal beams from the neighboring base station, where the first number and the second number are equal to or less than the predetermined number. The method further includes determining whether the measurement event occurs based on the first number of best signal beams from the serving base station and the second number of best signal beams from the neighboring base station, and sending a measurement report when the measurement event occurs.

Abstract: A method and apparatus for UE to report preference indication and other UE assistance information to the network is proposed. In a first embodiment, the UE transmits a power preference indication to the network with a prohibition mechanism for optimal DRX configuration. A first level of prohibition is applied if the UE indicates preferring power-saving mode, and a second level of prohibition is applied if the UE indicates preferring normal mode. In a second embodiment, the UE transmits two-level speed information to the network. The two-level speed information is mapped from MSE mobility states based on a mapping rule. In a third example, the UE transmits RRC release assistance information to the network. The assistance information is based on both cell change count and RRC state transition count so that RRC inactivity time can be determined to reduce signaling overhead.

Abstract: A method of reporting UE measurement state information in RLF report is provided. A UE performs radio measurements of a serving cell and neighbor cells in a mobile communication network. The UE evaluates a measurement reporting criteria and attempts to access the network to deliver a measurement report if the criteria is met. The UE then detects a radio link failure or a handover failure event and reconnects to the network by performing RRC reestablishment or RRC establishment. Finally, the UE transmits a failure event report to the network. The failure event report comprises UE measurement state information corresponds to the failure event. The UE measurement state information helps the network to determine whether to apply corrective actions to mitigate the failure.

Abstract: A method of inter-RAT failure event report is proposed. A UE detects a failure event in a first cell served by a first base station, and the first cell belongs to a first RAT. The failure event may include a radio link failure or a handover failure. The UE then performs an RRC establishment procedure with a second cell served by a second base station, and the second cell belongs to a second RAT. After the RRC establishment, the UE transmits a failure event report to the wireless network. The failure event can be a radio link failure, or be associated with a mobility command such as a handover command. By providing more reliable information in the failure event report than a network solution could provide, inter-RAT mobility performance can be improved.

Abstract: 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.

Abstract: A method of user equipment (UE) indication of traffic-related information to network is provided. The method comprises a UE determining a traffic indicator and transmitting the traffic indicator to a base station. In one embodiment, the traffic indicator indicates either that default power consumption is preferred or low power consumption is preferred. For example, when the UE is in background traffic or sparse traffic, low power consumption is preferred. In another embodiment, the traffic indicator indicates a time pattern of the traffic history. From the network perspective, upon receiving and evaluating information contained in the traffic indicator, the network triggers a QoS modification procedure by applying one or more QoS modification algorithms.

Abstract: An enhanced connection recovery upon lost RRC connection due to radio link failure (RLF) or handover failure (HOF) is proposed. A UE first establishes an RRC connection in a source cell in a mobile communication network. Later on, the UE detects a failure event and starts an RRC reestablishment procedure in a target cell to restore the RRC connection. In a first novel aspect, a fast NAS recovery process is applied to reduce the outage time in the target cell. In a second novel aspect, context fetching is used to reduce the outage time in the target cell. In a third novel aspect, a loss-less reestablishment procedure is proposed to reduce data loss during the connection recovery.

Abstract: Apparatus and methods are provided to enhance BSR and LCP procedures for the dual connectivity system. In one novel aspect, the BSR is handled for each MAC entity according to one or more allocation rules. In one embodiment, the allocation rule is configured by the network. In another embodiment, the allocation rule is determined by the UE based on historic statics. In yet another embodiment, the allocation rule is determined by the UE based on information from the network. In one embodiment, the allocation rule indicates percentage of traffic allocated to each MAC entity. In another novel aspect, LCP is performed independently for each MAC entity if the split bearer is configured and the prioritized bit rate (PBR) and the bucket size duration (BSD) are signaled for each eNB. In one embodiment, separate sets of LCG variables are maintained independently for each MAC entity.

Abstract: A method of providing location option control for Minimization of Drive Test (MDT) in LTE systems is provided. In one embodiment, a UE or an eNB receives an MDT location request that comprises an MDT location option configuration having one or more location options. The UE or eNB determines a first location option based on the MDT location option configuration and initiates positioning for MDT measurements, reporting, and logging according to the first location option. In one novel aspect, each location option is associated with a priority. In addition to MDT measurements, reporting, and logging, a UE determines the best positioning procedure from a list of available location options. In one novel aspect, under a specific positioning objective, the UE prioritizes the list of available location options based on the signal strength and/or quality of cellular and WLAN signals.
