    Abstract: A method for simultaneous Reception (Rx) or Transmission (Tx) associated with dual subscriber numbers using a single RF device in a User Equipment (UE) is provided. The UE determines whether a trigger condition for enabling simultaneous Rx or Tx operation associated with two separate subscriber numbers is met. In response to the trigger condition being met, the UE reports a first value representing an aggregated bandwidth or a number of CCs or MIMO layers for one of the two separate subscriber numbers to a mobile communication network via the single RF device, so as to enable simultaneous Rx or Tx operation associated with the two separate subscriber numbers. In particular, the first value is less than a second value representing a maximum aggregated bandwidth or a maximum number of CCs or MIMO layers supported by the UE's capability.

    Abstract: A User Equipment (UE) including a wireless transceiver and a controller is provided. The wireless transceiver performs wireless transmission and reception to and from a mobile communication network. The controller determines whether a trigger condition is met. In response to the trigger condition being met, the controller reports a first value representing a first Rank Indicator (RI) or a second value representing the UE's capability of Multiple-Input-Multiple-Output (MIMO) layers to the mobile communication network via the wireless transceiver. In particular, the first value is less than a third value representing a second RI derived from a measurement by the UE, or the second value is less than a fourth value representing a number of maximum MIMO layers supported by the UE.

    Abstract: A mobile communication device including a wireless transceiver and a controller is provided. The wireless transceiver performs wireless transmission and reception to and from a 3rd Generation Partnership Project (3GPP) network using a first Radio Access Technology (RAT). The controller establishes one or more radio bearers with the first 3GPP network via the wireless transceivers, and establishes a secure tunnel with a non-3GPP interworking gateway of a second 3GPP network via the radio bearers. The second 3GPP network utilizes a second RAT. Also, the controller registers, via the secure tunnel, an IP Multimedia Subsystem (IMS) service with an IMS server communicatively connected to the second 3GPP network, so as to make a voice call over the first 3GPP network.

    Abstract: A mobile communication device including a first RF device, a second RF device, and a controller is provided. The first and second RF devices perform wireless transmission and reception utilizing a first RAT and a second RAT, respectively. The controller detects, during a communication with a first cell using a first subscriber identity, an incoming event for making a voice call or conducting a data session using a second subscriber identity via the second RF device, and switches the communication associated with the first subscriber identity to a second cell which utilizes the first RAT in a frequency band on which dual connectivity over the first and second RATs is supported, or enables the voice call associated with the second subscriber identity to be made via the first RF device when the communication associated with the first subscriber identity is performed via the second RF device.

    Abstract: A wireless communication method and Multi-SIM user equipment are provided. The wireless communication method for Multi-SIM dual standby (DSDS) technology is applied on Multi-SIM user equipment (UE) which is capable of carrier aggregation (CA) or dual connectivity (DuCo). The wireless communication method includes the steps of determining whether a packet switch (PS) or circuit switch (CS) paging is received on a second SIM card when a first PS call is ongoing in a first SIM card; and suspending the first PS call which is ongoing on the first SIM card if the packet switch (PS) or circuit switch (CS) paging is received on the second SIM card.
