摘要： In various aspects, the disclosure provides user equipment (UE) capable of conducting a public land mobile network (PLMN) search by determining a paging schedule for a serving cell of the UE, the serving cell being associated with a first PLMN and the paging schedule defining one or more paging occasions. The UE may initiate a search for a second PLMN between consecutive paging occasions, and may read information blocks on a broadcast channel of a cell of the second PLMN. The UE may discontinue reading a partially-read information block when the partially-read information block is scheduled for transmission at least partially concurrently with a paging occasion on the serving cell if the partially-read information block does not include information for identifying the second PLMN. The UE may ignore the first paging occasion when the partially-read information block includes the information for identifying the second PLMN.

摘要： Certain aspects of the present disclosure relate to apparatuses and methods for maintaining reachability at a user equipment (UE). In one aspect, the apparatuses and methods are configured to detect a change in a radio connection between the UE and a peer entity, wherein the change in the radio connection is associated with the UE entering an idle state, to communicate to the peer entity, in response to detecting the change in the radio condition, an indication that the UE is to enter the idle state and is reachable for a specified duration of time while in the idle state, and to enter the idle state after communicating the indication to the peer entity. In another aspect, the apparatuses and methods are configured to communicate to the peer entity an indication that the peer entity is not to attempt to reach the UE during the specified duration of time.

摘要： A method and apparatus for wireless communications are provided. A first cell on which a user equipment (UE) is camped may be identified as a visited Public Land Mobile Network (VPLMN) of the UE. Information of a second cell among neighboring cells of the first cell may be received via a broadcast message from the first cell. The second cell may be part of a home PLMN (HPLMN) and the HPLMN may not be an equivalent PLMN (EPLMN) to the VPLMN associated with the first cell. Alternatively, the second cell may belong to an Equivalent HPLMN (EPLMN). When the second cell is determined to be a best cell according to absolute priority reselection rules or a highest ranked cell among the neighboring cells of the first cell, the second cell may not be barred for a period of time from being considered or identified as a candidate for reselection.

摘要翻译： 在各方面，本公开提供能够通过确定UE的服务小区的寻呼调度来执行公共陆地移动网络（PLMN）搜索的用户设备（UE），所述服务小区与第一PLMN相关联，并且寻呼时间表 定义一个或多个寻呼场合。 UE可以在连续的寻呼时段之间发起对第二PLMN的搜索，并且可以读取第二PLMN的小区的广播信道上的信息块。 如果部分读取的信息块不包括用于识别第二PLMN的信息，则部分读取的信息块被调度用于至少部分地与服务小区上的寻呼时机同时发送，则UE可以停止读取部分读取的信息块 。 当部分读取的信息块包括用于识别第二PLMN的信息时，UE可以忽略第一寻呼时机。
