    Abstract: Methods and apparatuses are provided that include providing transmit diversity for data channel transmissions. Different precoding vectors can be used over different slots of a given subframes to precode corresponding signals. The precoding vectors, in one example, can be orthogonal. In addition, using the different precoding vectors can be determined based on a user equipment receiving an indicator from a base station receiving the data channel transmissions of whether to use frequency hopping over the slots. Moreover, precoding vectors used to precode data channel transmissions can additionally or alternatively vary across subframes.

    Abstract: The present invention relates to a method for allocating communication resources in a multi-user cellular communication system, wherein communication resources are divided in time periods and frequency sub-bands, wherein part of the communication resources are used for frequency-localized communication channels, and part of the communication resources are used for frequency distributed channels. The method further comprises the steps of classifying part of the frequency sub-bands as frequency sub-bands carrying frequency-distributed channels, classifying the remaining part of the frequency sub-bands as frequency sub-bands carrying frequency-localized channels. The present invention also relates to a system, a transmitter and a communication system.

    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.
