    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.
