Abstract: Apparatus and methods are provided for user-plane 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. In one embodiment, a bridge/VLAN architecture is used. The UE identifies one or more Ethernet Frames received the WLAN interface as containing the PDCP PDUs by decoding the EtherType. In another embodiment, the WLAN terminated tunneling is used by decoding the EtherType of indicating the PDCP type. In another novel aspect, an UE-terminated tunneling is created.

Abstract: Enhanced paging mechanisms are proposed for Machine Type Communication (MTC) devices in 3GPP networks. First, adaptive paging is proposed to adaptively allocate extra paging occasions for MTC devices with no extra procedure or power consumption on normal UEs. Second, group paging is proposed to simultaneously page a plurality of MTC devices with one paging. Group paging is controlled in different levels for optimized signaling and easier management. In one embodiment, group broadcasting and group release are used. Third, paging with response policy is proposed to pre-define or dynamically configure paging response policies for MTC devices.

Abstract: A method of supporting group communication over LTE MBMS is provided. A UE first establishes a unicast Evolved Packet Service (EPS) bearer in an LTE network for group communication. The UE belongs to a communication group having a communication group ID. The UE receives access information from the network for monitoring downlink (DL) multicast traffic of the DL group communication based on a multicast decision. The UE is then ready for monitoring a multicast Multimedia Broadcast Multicast Service (MBMS) bearer for receiving the DL multicast traffic. The multicast MBMS bearer is associated with a Temporary Mobile Group Identifier (TMGI), and wherein the TMGI is associated with the communication group ID. The UE later enters RRC_IDLE mode and releases a radio bearer of the unicast EPS bearer while keep monitoring the multicast MBMS bearer for the DL multicast traffic.

Abstract: In a heterogeneous network, enhanced handover and reestablishment procedures are proposed within a local area network. The enhanced procedures are more efficient, e.g., with less signaling and less data interruption than the legacy mobility mechanism. In a local area network, a UE is served by an anchor eNB in macro cell layer and one or more drift eNBs in small cell layer. When the UE moves within the local area network, the UE anchor does not need to change. For cell change within the same anchor, the enhanced procedures reduces signaling overhead and data interruption time.

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: Apparatus and methods are provided for selection and data aggregation for the LWA. In one novel aspect, the UE connected with a first RAN receives a LWA assistance configuration and selects a second RAN based on the LWA assistance configuration. The UE aggregates data traffic from the first RAN and the selected second RAN. In one embodiment, the information request-and-response procedure is used, which allows the first RAN to query the UE about its second RAN association status. In another embodiment, the selection request-and-response procedure is used, which allows the first RAN to exercise some control over which base station of the second RAN is selected by the UE and for the UE to send relevant information about its second RAN connectivity to the first RAN. In another novel aspect, the UE selects a DRB based on the LWA DRB configuration through either a NAS procedure or an operator configuration.

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: 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 WiFi 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.

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.
