摘要： Apparatus and methods are provided to handle the intermittent disconnections in an mmW system. In one novel aspect, the beam tracking failure is determined upon detection of one or more tracking failure conditions. In one embodiment, the UE further considers potential recoveries to avoid frequent triggering of the beam-tracking failure condition. In another novel aspect, the UE performs one or more recovery procedures based on one or more recovery conditions. In one embodiment, the UE performs the initial alignment procedure to recover the connection. In another embodiment, the UE performs the beam-switching request procedure before triggers the initial alignment procedure. In one embodiment, timers are used to supervise the recovery procedures. In another embodiment, macro-assisted procedures are used for the beam-switching request procedure. In yet another novel aspect, the UE performs reestablishment of a new connection at the upper layer upon receiving the beam-tracking failure indicator.

摘要： Methods and apparatus are provided to measure, estimate throughput of wireless network for traffic offload. In one novel aspect, the UE determines the association status of a radio access network (RAN). The UE measures or estimates the end-to-end throughput of the RAN. In one embodiment, non-intrusive estimation by QoS probing request is used. In another embodiment, direct measurement with modeling is used. The modeling uses admission control/scheduling. In another embodiment, estimation or probing the metrics with or without modeling is used with either in-band probing or non-intrusive probing. In yet another embodiment, the throughput is obtained based on network signaling messages. In another novel aspect, the UE selects a dynamic measurement or estimation algorithm based on the association status and the QoS type of the traffic. Admission control procedure or binary admission procedure is used with the initial bandwidth request based on association status.

摘要： Apparatus and methods are provided to handle idle mode operation in the heterogeneous network with conventional macro cell and millimeter wave (mmW) small cells. In one novel aspect, the UE camps on both the macro cell and the mmW small cell. The UE receives system information that includes information of mmW small cells and paging messages from the macro cell and establishes RRC connection with one of the mmW small cell. In one embodiment, the UE performs mmW small cell discovery upon obtaining mmW small cell information. In another embodiment, the UE performs the mmW small cell discovery if the mobility status indicates low mobility and/or the traffic type is suitable for the mmW small cell. In another novel aspect, the UE receives the paging request from the macro cell and sends the paging response to the mmW small cell base station who forwards the paging response to the MME.

摘要： Methods are provided to perform multiple-connectivity operation in the heterogeneous network. In one novel aspect, multiple-connectivity is configured with one microwave macro cell and multiple small cells. UE establishes control plane connectivity with the microwave macro cell, where the S1-MME interface is terminated. Multiple small-cell base stations provide traffic data together to the UE and are connected with Xn interfaces. One small-cell base station in the set of the configured small base stations is an UP anchor small-cell base station, where S1-U interface is terminated. Other small base stations are UP assistance small base station. In one embodiment, the set of small base stations and the UP anchor small base stations can be changed based on the measurement report/results of the different cells as well as the cell loading status. The anchor base station can be changed either by the UE or through network configuration.

摘要： Methods and apparatus are provided for UE-centric measurement and connectivity control in macro-assisted heterogeneous network. In one novel aspect, the UE establishes a connection with a macro base station in a heterogeneous wireless network. The UE collects and analyzes UE status information locally. Subsequently, the UE autonomously initiates access to a small cell base station if access criteria are met based on the locally collected UE status information. In one embodiment, the UE informs the macro base station and the one or more small-cell base stations of the small-cell base station. In another embodiment, the UE starts a supervise timer before initiating access the one or more small-cell base stations and autonomously initiates a subsequent accessing procedure to another small cell base station upon detecting an access failure until the supervising timer expires. The UE stops the access procedure upon the supervise timer expires.
