Abstract: A method for inter-radio access technology (inter-RAT) performance enhancement in a mobile communications device is provided. First, a first RAT is camped on to perform a first service. Thereafter, it is moved/fallen back to a second RAT from the first RAT to perform a second service. Cell information of the first RAT is then measured and collected during the performance of the second service in the second RAT. A first cell to return to the first RAT is determined according to the collected cell information of the first RAT after a call connection of the second RAT is released.

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.
