Abstract: Certain aspects of the present disclosure propose techniques for resolving paging interval conflicts between two different radio access technology (RAT) paging intervals and for avoiding missing paging messages for a multimode terminal (MMT). Certain aspects provide a method for detecting messages associated with paging, by an MMT supporting multiple-input multiple-output (MIMO), from first and second networks using first and second RATs, such as Time Division Synchronous Code Division Multiple Access (TD-SCDMA) and Code Division Multiple Access (CDMA) IxRTT (Radio Transmission Technology), Evolution-Data Optimized (EVDO), or Wideband CDMA (WCDMA). The method generally includes using a first MIMO receive chain of the MMT to detect a first message associated with paging from the first network and simultaneously using a second MIMO receive chain of the MMT, different from the first receive chain, to detect a second message associated with paging from the second network.

Abstract: Avoidance of uplink synchronization oscillation in TD-SCDMA systems begins when a user equipment receives a downlink SS command from a Node B. The user equipment obtains a previous uplink timing, which may be from a previous sub-frame associated with the downlink SS command. The user equipment would obtain this previous sub-frame associated with the SS command directly from the Node B as an identification of the Node B's sub-frame delay. The user equipment will then calculate the uplink timing for its next updated uplink signal by combining the previous uplink timing with the synchronization adjustment associated with the SS command. The user equipment then transmits its next uplink signal using the new uplink timing.

Abstract translation: 当用户设备从节点B接收到下行链路SS命令时，TD-SCDMA系统的上行链路同步振荡的避免开始。用户设备获得可能来自与下行链路SS命令相关联的先前子帧的先前的上行链路定时。 用户设备将直接从节点B获得与SS命令相关联的该先前子帧作为节点B的子帧延迟的标识。 然后，用户设备将通过将先前的上行链路定时与与SS命令相关联的同步调整组合来计算其下一个更新的上行链路信号的上行链路定时。 用户设备然后使用新的上行链路定时发送其下一个上行链路信号。

Abstract: Open loop power control in Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) multi-carrier systems is facilitated through the determination of a value for open loop control on a primary carrier frequency which is then used to perform open loop control on at least one secondary carrier frequency in the multi-carrier system. This determined open loop control value may be applied using the value determined on the primary carrier frequency, or may be further adjusted using an estimated difference between received power of the primary carrier frequency and the secondary carrier frequencies, in selected aspects. When the pilot signals in the secondary carrier frequencies are transmitted at different power levels, this open loop control value may be further adjusted with a transmit power level offset.

Abstract: Certain embodiments of the present disclosure proposes a flexible method for scheduling of an uplink transmission simultaneously considering all active connections of a mobile station. A decision on scheduling priority can be made based on a metric that comprises QoS parameters and current traffic measurements. The weight factors may be applied for every QoS parameter per schedule type providing flexibility of the scheduling algorithm. The proposed scheduling algorithm may be applied to satisfy different QoS requirements for each service provider and application by changing weight factors if required.

Abstract: A mobile device capable of communicating on multiple radio access networks simultaneously may concurrently operate calls of a first call type on a first network and a second call type on the second network. As the mobile device approaches the limits of the service area of the second network it may take measurements to result in the call of the second call type to be serviced by the serving cell of the first network which is serving the mobile device for the first call type. In this manner the mobile device may ensure that when it leaves the service area of the second network, the calls of the first call type and second call type are served by the same serving cell in the first network.
