Abstract: Certain embodiments of the present disclosure provide a method for communicating by a multi-mode mobile station (MS) with first and second networks via first and second radio access technologies (RATs). The method generally includes measuring a time offset between frames of the first RAT and frames of the second RAT while maintaining a connection with the first network via the first RAT, sending a request to a base station of the first network to establish scan periods during which the MS may switch to the second network to monitor for paging messages, and switching to the second network to monitor for paging messages during a scan period without terminating the connection with the first network. The first RAT may comprise, for example, WiMAX, while the second RAT may comprise, for example, CDMA.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided for prioritizing the performance of measurements during measurement gaps and the reception of multicast/broadcast content. The apparatus receives a configuration from a serving cell to perform a measurement during a measurement gap of a unicast service while in a connected mode. In addition, the apparatus determines whether to refrain from leaving the serving cell on a first frequency and performing the measurement on a second frequency of a neighboring cell in order to receive multicast/broadcast content associated with a multicast/broadcast service during the measurement gap.

Abstract: Uplink synchronization processes in multi-carrier time division-synchronous code division multiple access (TD-SCDMA) systems include determining uplink transmission timing for a first carrier frequency and performing uplink synchronization on the other carrier frequencies based on the transmission timing of the first carrier frequency. The transmission timing may be adjusted based on a timing offset that is measured between the received downlink pilot signals of the various carrier frequencies. User equipment may perform uplink synchronization individually with each of the carriers serviced by a particular Node B after receiving synchronization information regarding those carrier frequencies.

Abstract: In geographical areas with incomplete Time Division Synchronous Code Division Multiple Access (TD-SCDMA) coverage, it may be beneficial for a multimode User Equipment (UE) to handover to a GSM network, a WCDMA network, a CDMA 1x RTT network, or an LTE network. When multiple networks are available to the UE and a poor signal quality is detected in the TD-SCDMA network, one of the available networks may be selected for inter-RAT handover based on a service type of the active call on the UE. For example, when a circuit-switched call, such as a voice call, is in progress on the UE, an inter-RAT handover to a GSM network occurs. In another example, when a packet-switched call, such as a data call, is in progress on the UE, an inter-RAT handover to a WCDMA network occurs. Selecting a network for inter-RAT handover based on an active call service type improves the service provided to the UE.

Abstract: Methods and apparatuses are provided that pausing transmission control protocol (TCP) transmissions during or following handover to prevent unwarranted duplicated acknowledgement transmission, which can cause decrease in TCP window size. During handover, transmission on-hold commands can be sent to a TCP layer that indicate to prepare to pause TCP transmissions, immediately pause TCP transmissions, and/or the like. Transmission resume commands can be sent to the TCP layer following handover. In addition, TCP transmissions can be paused following handover to allow data forwarding data to be provisioned to a device from a target base station without duplicated acknowledgement transmission.
