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： 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 for paging transmission and reception for UEs requiring coverage extension/coverage enhancement. In one novel aspect, the UE reports the CE status to the MME. CE level related information and the corresponding cell ID are provided from eNB to MME. MME sends paging information including the repetition number to all eNBs in the corresponding tracking area when paging the UE. In another novel aspect, a paging area is used for CE UEs. The UE receives paging area information, notifies the network, and updates the stored paging area information upon detecting changes between the received and the stored paging areas. In another embodiment, the UE reports its CE status upon detecting CE status changes. The eNB stores UE CE information and forwards it to neighboring eNBs in the same paging area. The eNB pages UEs on its CE UE list with repetition while paging other UEs normally.

摘要： Aspects of the disclosure provide a method of beam failure handling. The method can include performing beam quality measurement of one or more beams transmitted from a base station (BS) at a user equipment (UE) in a beamformed wireless communication system, determining a beam failure occurs based on the beam quality measurement, and performing a beam recovery process that includes at least one of a contention-free beam recovery process or a contention-based beam recovery process. The one or more beams are used for transmitting physical downlink control channels (PDCCHs).
