Abstract: A communication device includes a wireless transceiver circuit and a processor. The wireless transceiver circuit transmits and receives wireless signals. The processor processes the wireless signals to obtain information regarding a first period configured by a serving network device in order to measure signal strength of the serving network device and obtain information regarding a second period configured by the serving network device in order to detect a neighbor network device. The processor further determines whether an event related to low communication delay is triggered. When determining that the event related to low communication delay is not triggered, the processor performs a detection operation to detect the neighbor network device according to the second period. When determining that the event related to the low communication delay is triggered, the processor performs the detection operation to detect the neighbor network device according to a third period shorter than the second period.

Abstract: A scheduling method and a method for establishing a schedule list for user equipment (UE) of NB-IoT are provided. The method for establishing the schedule list includes the following steps: synchronizing to a cell; receiving at least one system information parameter from the cell, the at least one system information parameter including at least one system information type and a narrowband system information block type; establishing multiple sub-lists according to the distributions of the at least one system information type and the narrowband system information block type, each element of the sub-lists representing an available subframe; assigning a sub-list code to each sub-list; calculating the number of elements for each sub-list; and establishing a list according to the at least one system information parameter, the sub-list codes, and the numbers of the elements.

Abstract: A scheduling method for user equipment (UE) of NB-IoT is provided. The scheduling method includes: synchronizing to a cell; receiving from the cell at least one system information parameter that includes a maximum number of repetitions, periods, and offsets of NPDCCH search spaces; establishing a list according to the at least one system information parameter, the list recording multiple available subframes and each available subframe being labeled with an index; calculating a numeral of a start subframe of target NPDCCH repetitions according to a numeral of a target subframe, the period, and the offset; searching the list for a start index corresponding to the start subframe using the numeral of the start subframe; searching the list for a target index corresponding to the target subframe; determining whether the target subframe is within the interval of the target NPDCCH repetitions; and determining whether the target subframe is an NPDCCH candidate subframe.
