Mobile communication device for collecting system information and cell measurement using DRX gap and autonomous gap

A mobile communication device, comprising:

• a transceiver, configured to establish a connection to a serving cell, receive a measurement request for a first target cell, and receive a second measurement request for a second target cell, and wherein the transceiver is configured to take measurements for the first and second target cells in first and second frequencies, respectively;
• and wherein the first and second frequencies are proportional to first and second numbers of frequencies adopted by the first and second target cells, respectively;
• and
• a controller, coupled to the transceiver, configured to in response to the measurement request, acquire first timing information of first system information for a first target cell, schedule an autonomous gap corresponding to occurrence of the first system information according to the first timing information, and initiate the autonomous gap to receive the first system information from the first target cell, and;
• wherein when the first system information is absent from the portion of the DRX gap, the transceiver is configured to take measurements for the first and second target cells in a priority order;
• wherein the controller is further configured to determine whether the occurrence of the first system information coincides with a portion of a DRX gap;
• and
• when the occurrence of the first system information coincides with the portion of the DRX gap, the transceiver is configured to receive the first system information in the portion of the DRX gap.
