    Abstract: In geographical areas with incomplete coverage of Time Division Synchronous Code Division Multiple Access (TD-SCDMA) networks, it may be beneficial for a multimode User Equipment (UE) to handover to a Global System for Mobile Communications (GSM) network. Before handover, a multimode UE may receive an indication from a serving TD-SCDMA cell to enter a Discontinuous Reception (DRX) mode and perform measurement on a nearby GSM cell. After measurement, the UE receives a grant from the serving TD-SCDMA cell allowing the UE to transmit a measurement report to the serving TD-SCDMA cell. The TD-SCDMA cell may use the measurement report to determine if the multimode UE should handover to the GSM cell.

    Abstract: Certain embodiments of the present disclosure provide a unified scheme for selecting an operator and a radio access technology (RAT) by a multi-mode wireless device during a power-up or a handover process.

    Abstract: Aspects of the present disclosure allow a mobile station (MS) to maintain data activity while performing handover operations within the WiMAX network and listening to a CDMA 1x paging cycle. According to aspects, the MS maintains timing of a base station (BS) in a first radio access technology (RAT) and a BS in a second RAT. The MS may determine an expected timing of a paging cycle in the second RAT and send a sleep request to the BS in the first RAT such that the sleep interval coincides with the timing of the paging cycle in the second RAT. The MS may perform operations to ensure a sleep interval, after performing handover operations, coincides with the timing of the paging cycle in the second RAT.

    Abstract: Techniques for deriving message counts based at least in part on a locally stored message count and at least a portion of a message count received from a remote network node are disclosed. The message counts can relate to downlink (DL) non-access stratum (NAS) counts. In one aspect, a device can receive a number of least significant bits of the DL NAS count in a handover message. The device can derive a DL NAS count by utilizing a remaining portion of most significant bits of a locally stored DL NAS count, and can determine whether to increment or decrement the most significant bits based at least in part on a parameter to handle cases where the least significant bits of the locally stored DL NAS count have wrapped due to overflow and/or underflow.

    Abstract: Techniques for scheduling logical channels for data transmission are described. In one design, a user equipment (UE) is configured with a plurality of logical channels for sending data on the uplink. Each logical channel is associated with a priority and a data buffer size. The UE maintains a token bucket for each logical channel. In each scheduling interval or when an uplink grant is received, the UE determines a bucket level (which may be a positive value or a non-positive value) for each of the plurality of logical channels. The UE ascertains logical channels with bucket levels of the same polarity and then identifies logical channels of the same priority among all logical channels with the same bucket level polarity. The UE selects at least one identified logical channel for scheduling based on the data buffer size and/or the bucket level for each identified logical channel.

    Abstract: Wireless communication is implemented by a multi-mode user equipment (UE). The method includes selecting a continuous time period during a Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) voice call. The voice call is via a Node B. The selected continuous time period includes multiple subframes. The method also includes preventing the UE from communicating with the Node B during the selected continuous time period, or at least preventing downlink communications with the Node B. The method further includes acquiring a Global System for Mobile communications (GSM) signal from at least one GSM cell during the selected continuous time period. The UE can handover to a selected GSM cell based on the measurements of the acquired GSM cell(s).
