Abstract: Aspects for pruning a spurious cell are provided for a user equipment (UE). At the UE, based in part on transmission gap pattern sequence (TGPS) information received from a serving cell of the UE, a search period for measurement events for cells in a database different from the serving cell is determined. Among the cells in the database in the UE, a candidate cell is selected. Among a plurality of measurement reporting event time-to-triggers (TTTs) associated with the candidate cell, a smallest measurement reporting event TTT is determined. Further, based at least in part on the search period and the smallest measurement reporting event TTT value associated with the candidate cell, a cell age pruning threshold for the candidate cell may be determined. The cell age pruning threshold may be used to determine whether to prune the candidate cell from the database.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for implementing one or more ECCE index determinations for MPDCCH in special subframes in eMTC using communications systems operating according to new radio (NR) technologies. For example, a method for wireless communications may include determining a type of channel is scheduled to be transmitted across multiple subframes, determining a first subframe of the multiple subframes is of a first subframe type that is different than a second subframe type of one or more other subframes of the multiple subframes, and determining resources for a decoding candidate of a channel based, at least in part, on the first subframe type and the second subframe type.

Abstract: A method for reacquiring a cell after tune-away for an MSMS mobile communication device includes: measuring pilot signal energy of a cell on which a data call was suspended on a first subscription before tune-away; determining whether the measured pilot signal energy is less than a high threshold RSSI value; determining whether a difference between a measured cell timing and a pre-tune-away cell timing is less than a first threshold timing value; determining whether a strongest pilot signal energy received on one of a plurality of rake fingers is greater than a low threshold RSSI value; decreasing the low threshold RSSI value for reacquiring the cell; and in response to determining that the measured RSSI for the strongest pilot signal energy received on one of the plurality of the receiver rake fingers is not less than the decreased minimum threshold RSSI value, reacquiring the cell and resuming the data call.

Abstract: The present disclosure describes a method and an apparatus for pruning false peaks during slot synchronization at a user equipment (UE). For example, a method is provided to identify a plurality of first peaks associated with a primary-synchronization channel (P-SCH) received at the UE and a plurality of second peaks from the plurality of first peaks. Further, one or more pruning locations along with associated energy thresholds for each of the plurality of the second peaks may be determined and whether a peak of the plurality of the first peaks is a false peak is identified based on whether the peak is located at one of the one or more pruning locations of the peak and an associated energy value of the peak does not satisfy the associated energy threshold of the pruning location. Furthermore, the peak identified as the false peak is discarded.

Abstract: The present disclosure provides a mechanism that may allow a UE to determine whether PBCH repetition is enabled in the target cell without performing a hypothesis test. For example, the apparatus may receive a handover message from a serving cell. In an aspect, the handover message may be associated with a handover procedure to a target cell. In addition, the apparatus may determine whether to perform a hypothesis test to determine if a PBCH repetition is enabled in the target cell based on the handover message. In one example, the apparatus may determine not to perform the hypothesis test when the handover message includes information that indicates if the PBCH repetition is enabled in the target cell. In another example, the apparatus may determine to perform the hypothesis test when the handover message does not include information that indicates if the PBCH repetition is enabled in the target cell.

Abstract: Methods and apparatus for wireless communication for improving back to back cell reselection that includes establishing that cell reselection to a primary candidate cell has failed. Afterwards, a UE determines if a set of predetermined conditions have been triggered and schedules cell reselection to a secondary candidate based on whether the set of predetermined conditions have been triggered.
