Abstract: The present disclosure presents a method and an apparatus for network cognizant uplink transmissions during inter radio access technology (IRAT) handovers. For example, the method may include skipping inter radio access technology (IRAT) measurements during one or more dedicated channel (DCH) measurement occasion (DMO) or idle interval gaps of a transmission timing interval (TTI). The method further includes transmitting data on an uplink from a user equipment (UE) to a network entity during the entire duration of the TTI and determining whether the network entity is decoding the data transmitted on the uplink based on a response received from the network entity. As such, network cognizant uplink transmissions during inter radio access technology (IRAT) handovers may be achieved.

Abstract: A user equipment (UE) enables reselection by supplementing dedicated priority information received from a network with proprietary priority-based reselection parameters stored in a UE memory. The reselection is performed when a currently camped-on cell does not broadcast priority-based reselection parameters. The proprietary priority-based reselection parameters include threshold parameters such as high priority thresholds, low priority thresholds, signal strength thresholds and related reselection timers.

Abstract: A method of wireless communication determines whether the timing of a non-serving RAT is known. When the timing is known and it is time to report on the non-serving RAT, the UE clears enough consecutive time slots to verify the identity of the base station in the non-serving RAT. During the cleared time slots the identity of the base station is verified. When the timing is unknown and it is time to report on the non-serving RAT, a UE clears enough consecutive time slots to measure the timing of the non-serving RAT and to verify the identity of a base station in the non-serving RAT. During the cleared time slots, the timing is acquired and the identity of the base station is verified.

Abstract: A method of wireless communication includes recording an absolute system frame number (SFN) of a target radio access technology (RAT) and/or recording a relative system frame number (SFN) difference between a serving radio access technology (RAT) and the target RAT. A transmission time interval (TTI) boundary, is determined after redirection, based at least in part on the recorded absolute frame number (SFN) and/or the recorded relative system frame number (SFN) difference.

Abstract: A user equipment (UE) may scale down a signal strength of a radio access technology (RAT) cell in a report to a serving cell to avoid multiple connection attempts to the same radio access technology cell. The UE may initiate a predefined timer, called a target cell timer, on which the scaling down of the reported signal strength of the particular RAT cell is based. The timer is initiated when the UE returns back to the serving cell after failure to access a top ranked RAT neighbor cell.

Abstract: The present disclosure presents a method and an apparatus for inter radio access technology (IRAT) cell reselection. For example, the method may include identifying that a user equipment (UE) in an idle or a discontinuous reception (DRX) mode is camped on a cell of a first RAT, determining that the cell the UE is camped on is not broadcasting any neighbor cell of a second RAT, scanning for one or more frequencies of the second RAT based on the determination, and triggering a cell reselection to a cell of the second RAT, wherein the cell of the second RAT is associated with a frequency identified during the scanning. As such, an autonomous IRAT cell reselection may be achieved.
