Abstract: Apparatus and methods are provided for LWA PDU routing. In one novel aspect, LTE PDU packets are routed through a WLAN AP to a UE by encapsulation of the data packets. An adaption layer encapsulate the whole packet as an Ethernet frame by appending the Ethernet MAC header to the payload. In other embodiments, the adaption layer encapsulates LTE PDU as GRE packet, configures VLAN for WLAN AP. In another novel aspect, the LTE PDU is identified by at least one of methods comprising the EtherType value, the source address, the GRE header, and the GTP header. In another embodiment, the default path is always used for LWA routing. In yet another novel aspect, the LTE PDU is forwarded by the MAC address, by the GRE tunnel configuration, or by the GTP tunnel configuration.

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: 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 collecting and providing traffic statistics in a cellular network in accordance is proposed. A UE establishes an RRC connection with a base station. The UE starts to collect traffic statistics that comprises a CDF curve or a PDF diagram for packet inter-arrival time. The UE may receive a measurement configuration from the base station for the traffic statistics collection. The UE then reports a representation of the traffic statistics to the base station for RRC reconfiguration. The UE may also receive a reporting request from the base station that specifies a representation format. The representation format includes one or more probability values at corresponding inter-arrival time points, at least one slope of the CDF, one or more steep events in the CDF, or a PDF range.

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。

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 uplink shaping and scheduling request (SR) prohibition in RRC Connected Mode is proposed. A UE applies DRX operation in a wireless network, the UE is in RRC Connection mode. 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 transmits a scheduling request (SR) to the network. If the data packet belongs to a background traffic type, then the UE buffers the data packet and is prohibited from sending the SR to the network until a triggering condition is satisfied. By reducing the activity of uplink transmission, UE power consumption is improved and signaling overhead is reduced.
