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.

Method and apparatus for maintaining reachability of a user equipment in idle state

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.

Method to improve public land mobile network search

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.
