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: Various schemes are provided to improve SR resource utilization by adapting SR resource allocation to traffic pattern. In a first Scheme, SR resource allocation is configured more accurately. In one example, UE provides assistant information for eNB to determine or adjust SR configuration based on the received assistant information. In a second Scheme, multiple SR periods are configured and adapted to traffic pattern. In one example, eNB configures a set of SR resources with multiple SR periods, and UE applies different SR periods based on predefined events. Unused SR resources could be recycled by eNB for PUSCH data transmission. In a third Scheme, multiple SR allocations are configured and adapted to concerned applications. In one example, eNB configures multiple sets of SR resources adapted to predefined applications, and UE applies SR configurations based on corresponding applications. The additional SR configurations could be activated and/or deactivated.

Abstract: A method of triggering and reporting traffic statistics in a cellular network is proposed. A UE establishes an RRC connection with a base station. The UE collects traffic statistics upon detecting a trigger event. The traffic statistics comprises packet inter-arrival time. The trigger event may be detected by the UE or by the base station. The UE then determines a representation of the traffic statistics and report the result to the base station. The report may be triggered by the UE or by the base station based on another trigger event. Upon receiving the traffic statistics, the base station determines RRC reconfiguration parameters. In one example, DRX timer values are determined based on intra-burst packet inter-arrival time. In another example, RRC release timer is determined based on inter-burst packet inter-arrival time.

Abstract: LWA (LTE/WLAN Aggregation) is a tight integration at radio level which allows for real-time channel and load aware radio resource management across WLAN and LTE to provide significant user perceived throughput (UPT) improvement. When enabling LWA, packets are routed to a base station (eNB) for performing PDCP functionalities as an LTE PDU. Afterwards, the eNB can dispatch the PDU either delivered over LTE link or WLAN link. The UPT improvement depends on how the eNB dispatches the PDU over LTE link or WLAN link. In one novel aspect, the eNB can acquire channel information, load information, and throughput estimation regarding with WLAN link and LTE link. As a result, the eNB can optimize UPT and LWA PDU dispatching algorithm.

Abstract: LTE-WLAN aggregation (LWA) at the radio access network level promises significant gain in system capacity and user quality of experience (QoE). In order to support QoS over LWA, there is a need to develop mechanisms to ensure that the access category (AC) classification chosen by a wireless device (AP in the case of downlink, and UE in case of uplink) is consistent with the QoS requirements of the EPS bearer/DRB and/or subscriber profile to which the traffic belongs. The cellular LTE network can provision QoS for both downlink and uplink data flows that are transferred using LWA access.

Abstract: A UE establishes an RRC connection with a base station for an application in a mobile communication network. The UE acquires a barring indication that indicates whether scheduling request (SR) barring is applicable for the application. The UE then acquires prioritized barring parameters for SR barring if applicable. The prioritized barring parameters is associated with a priority of the application. Finally, the UE determines whether to send a scheduling request for an arrived packet based on the prioritized barring parameters. In one embodiment, the application is associated with a quality of service (QoS) class indicator (QCI), and the priority of the application is based on the QCI. The prioritized SR barring mechanism based on QCI can be applied for RRC Connected mode with finer granularity.

Abstract: A method of uplink shaping and extending UE in RRC Idle Mode is proposed. The UE processes a data packet to be sent to the network. The data packet is associated with a traffic type. If the data packet belongs to a normal traffic type, then the UE enters RRC Connected mode and thereby transmitting the data packet to the network. If the data packet belongs to a background traffic type, then the UE buffers the data packet and the UE is prohibited from entering RRC Connected mode until a triggering condition is satisfied for uplink transmission. The proposed mechanism achieves power saving by reducing the activity of uplink transmission. In addition, the proposed mechanism also reduces signaling overhead to enhance network efficiency.

Abstract translation: 提出了一种在RRC空闲模式下上行整形和扩展UE的方法。 UE处理要发送到网络的数据包。 数据包与流量类型相关联。 如果数据包属于正常流量类型，则UE进入RRC连接模式，从而将数据包发送到网络。 如果数据包属于后台流量类型，则UE缓存数据包，并且禁止UE进入RRC连接模式，直到满足上行链路传输的触发条件为止。 提出的机制通过减少上行传输的活动实现节电。 此外，所提出的机制还减少了信令开销以提高网络效率。
