Abstract: Methods and apparatus for communicating with a multimode mobile station supporting multiple radio access technologies (RATs) are provided. For certain embodiments, when a paging request (824) is received via a first RAT network, paging requests may be broadcast on all RATs supported by the mobile device. As a result, the mobile device may receive the paging request regardless of which RAT (820) it used for a current network connection.

Abstract: A method for efficiently performing ranging in a wireless communication network may be implemented by a mobile station. The method may include sending a ranging code to a base station. The method may also include receiving a ranging response message from the base station. The method may also include determining whether a ranging failure condition is satisfied. The ranging failure condition may relate to something other than a duration of time. The method may further include re-sending the ranging code to the base station if the ranging failure condition is satisfied.

Abstract: Methods and apparatus for decoding MAP information elements (MAP IEs) in an orthogonal frequency-division multiplexing (OFDM) or orthogonal frequency division multiple access (OFDMA) frame, even when the received downlink (DL) or uplink (UL) MAP message cyclic redundancy check (CRC) fails, may be provided. By continuing to parse the MAP IEs in the MAP message despite a CRC failure in the MAP message or a data burst, the packet error rate may be reduced, and the wireless system throughput may be increased.

Abstract: Certain embodiments of the present disclosure provide a method for scanning for paging messages in a second radio access technology (RAT) network, such as a CDMA network, while connected to a first RAT network, such as a WiMAX network. For certain embodiments, an enhanced scanning request message may facilitate establishing a scanning cycle in the first RAT that aligns with a paging cycle of the second RAT.

Abstract: Methods and apparatus for base-station-assisted handover between WiMAX (Worldwide Interoperability for Microwave Access) and CDMA (Code Division Multiple Access) EVDO (Evolution-Data Optimized) or 1xRTT (one times Radio Transmission Technology, or 1x) networks during normal operation of a dual-mode mobile station (MS) are provided. By having a base station (BS) using one radio access technology (RAT) broadcast information about a BS in a neighboring cell employing a different RAT, the methods and apparatus may improve service continuity during handover.

Abstract: This disclosure provides systems, methods, and apparatus for wireless communications that support fast user equipment (UE) handover between base stations. A UE may receive, from a source base station, a configuration for reference signal transmission at a set of uplink transmit power levels. The UE may transmit multiple uplink reference signal repetitions based on the configuration. The source base station may transmit a request message to a target base station to measure the multiple uplink reference signal repetitions. The target base station may select an uplink reference signal and measure a transmit power correction. The target base station may transmit an indication to the source base station of the selection and transmit power correction. The source base station may evaluate the indications and select the target base station. The source base station may forward to the indicated contents, and the UE may switch and synchronize with the target base station.

Abstract: Aspects directed towards Quality of Service (QoS) flow remapping are disclosed. In an example, upon detecting a mapping reconfiguration of a first QoS flow from a first data radio bearer (DRB) to another DRB, a Service Data Adaptation Protocol (SDAP) control protocol data unit (PDU) is generated indicating that a final SDAP data PDU associated with the first QoS flow has been transmitted on the first DRB. The SDAP control PDU is then transmitted via the first DRB. In another example, upon detecting a mapping reconfiguration of a first QoS flow from a first DRB to another DRB, an end marker parameter is set in an SDAP header of a first SDAP data PDU received from an upper layer after the mapping reconfiguration indicating that the first SDAP data PDU is a final SDAP data PDU associated with the first QoS flow transmitted on the first DRB.
