Method for service data transmission, a receiver, a mobile terminal, a transmitter and a base station

A receiver, comprising:

• a radio frequency module, configured to receive a control signal sent from a base station which a mobile terminal accesses, and output the same to a receiver control module, and configured to receive subsequent service data from the base station, wherein the control signal is used for indicating more than one subcarriers allocated to the mobile terminal and the more than one subcarriers are used for transmitting service data;
• and
• the receiver control module, configured to judge whether the different between the highest frequency FREhigh and the lowest frequency FRELow in the more than one subcarriers exceeds a threshold value THB, if the difference does not exceed the threshold value THB, then receive the service data using a narrowband mode, otherwise receive the service data using a broadband mode;
• the receiver further comprising:
• a low pass filter module, an analog digital converter module, a Fourier transform module, a low power consumption control module, a de-mapping module, a channel estimation module, a demodulation module, and a decoding module, wherein
• the low power consumption control module is respectively in connection with the radio frequency module, the low pass filter module, the analog digital converter module and the Fourier transform module and is configured to respectively configure, under the control of the receiver control module, working parameters for the radio frequency module, the low pass filter module, the analog digital converter module and the Fourier transform module under a narrowband working mode.

A transmitter, comprising:

• an encoding mode, a debugging module, a mapping and multiplexing module, an inverse Fourier transform module, a digital analog converter module, a radio frequency module and a scheduling module, wherein the scheduling module comprises:
• a mode confirming submodule, configured to judge whether a current service of a mobile terminal which accesses a base station is a non-high speed transmission service, if yes, then trigger a configuring submodule to configure corresponding frequency resource of a narrowband mode for the mobile terminal;
• and
• the configuring submodule, configured to allocate more than one subcarriers to the mobile terminal, generate a control signal which indicates the more than one subcarriers, and control the radio frequency module to send the control signal to the mobile terminal, wherein the more than one subcarriers are used for service data transmission and the difference between the highest frequency FREhigh and the lowest frequency FRELow in the more than one subcarriers does not exceed a threshold value THB.
