Abstract: A communication apparatus is provided. A processor is coupled to a first radio access technology (RAT) module, a second RAT module and a radio transceiver shared by the first and second RAT modules. The first RAT module camps on a first serving cell belonging to a first wireless network and is in a packet transfer mode to perform data transfer in the first wireless network via the radio transceiver. The second RAT module camps on a second serving cell belonging to a second wireless network. The processor schedules the second RAT module to receive at least one neighbor cell's information in a portion of a plurality of predetermined frames during the data transfer of the first RAT module via the radio transceiver.

Abstract: A surrounding cell monitoring method is applied in a mobile terminal wirelessly communicating with a first cell through a first target channel. The surrounding cell monitoring method includes the steps of: determining whether adjacent channel interference (ACI) of the target channel exists; determining whether a first power level of the adjacent channel is greater than a second power level of the target channel by a threshold difference when the ACI exists, when the ACI does exist; determining whether an adjacent BSIC of the adjacent channel can be decoded when the first power level is greater than the second power level by the threshold difference; and skipping an operation of decoding a target BSIC of the target channel when the adjacent BSIC of the adjacent channel can be decoded successfully.
