    Abstract: Executing a FOTA (firmware over the air) method in a LoRa network having low throughput and low power. the transceivers used in the end nodes and in the LoRa gateway are capable of selecting a certain frequency channel and deactivating the LoRa mode. If the spread-spectrum LoRa mode is deactivated, both transceivers at the end node and the gateway function instead using a basic FSK (frequency-shift keying) modulation scheme. This modulation scheme is capable of providing a higher data rate at the expense of reducing the “path balance,” which indicates how much attenuation the transmitted signal may sustain while still being able to be decoded at the receiver. When using the FSK modulation scheme at a high data rate, a FOTA method may be easily carried out, since the end node must have its receiver activated only for a short time.

    Abstract: A radio receiving apparatus according to the present invention receives a preamble signal through one frequency band and also detects a periodic symbol timing in a receiving period of a part of a symbol that composes the preamble signal. A frequency correction circuit includes a generating unit, a detecting unit, and a correction unit. The generating unit generates a detection window of a predetermined time width including each of a first and a second symbol timing that are previously determined among the periodic symbol timings in the receiving period of a remaining symbol that composes the preamble signal. The detecting unit sequentially receives a correlation value between the preamble signal and a reference signal and detects a maximum value from the correlation value input during a period when the detection window is opened. The correction unit corrects a frequency deviation of the one frequency band based on the maximum value.

    Abstract: A method of allocating communication resources for a communication between a transmitter and a receiver in a communication system, the communication resources being divided in time periods and frequency sub-bands. The transmitter receives a channel quality measurement sent by the receiver. The transmitter performs allocation of a first part of the communication resources to the receiver according to the channel quality measurement if allocation of the first part is selected, or allocation of a second part of the communication resources to the receiver if allocation of the first part is not selected. The transmitter informs the receiver of allocated communication resources, and the allocated communication resources being designated for frequency localized channels or for frequency distributed channels.
