Methods, systems, apparatuses, and devices are described for managing wireless communication at a user equipment (UE). An exemplary method includes adding an identifier of a cell to a sub-optimal cell list based at least in part on a cell classification determination made by the UE, and avoiding a cell access procedure for the cell based at least in part on inclusion of the identifier in the sub-optimal cell list. Another exemplary method includes maintaining a sub-optimal cell list and an associated priority service exception list, initiating a service on the priority service exception list, identifying inclusion of a cell on the sub-optimal cell list, where the cell is associated with a cell access procedure initiated for the service, and accessing the cell included in the sub-optimal cell list based at least in part on inclusion of the service in the priority service exception list.

Identifying, avoiding, and/or allowing limited access to sub-optimal cells

Information can transfer from a transmitter to a receiver; however, the transmission can consume valuable resources. Therefore, a number of times a transmission is attempted can be tracked and compared against a threshold value. If the transmission occurs too many times&#x2014;based upon the comparison&#x2014;then a reset can occur. Tracking can occur for a protocol data unit and/or a control protocol data unit to determine if a reset should occur.

Protocol data unit recovery

A method for supporting emergency cell broadcast (CB) messages on a multi-subscriber identity module (SIM) mobile communication device includes: waking up a first subscription from a sleep mode at a common traffic channel (CTCH) occasion; decoding a CB message header received during the CTCH occasion; determining whether a scheduling message (SM) is present based on the decoded CB message header; and in response to determining that the SM is present, granting resource priority to the first subscription to decode the complete SM.

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

Methods and apparatus of cell detection include determining whether communication between a user equipment and a serving cell satisfies a serving cell unsuitability condition. The methods and apparatus further include performing one or more autonomous search procedures based on whether the serving cell unsuitability condition has been satisfied. Moreover, the methods and apparatus include conducting cell reselection based on one or more results from the one or more autonomous search procedures, wherein the one or more results indicate at least one suitable cell for reselection.

Methods and apparatus for enhanced cell detection

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.
