Abstract

The invention discloses a service data transmission method, a receiver, a mobile terminal, a transmitter and a base station. The method comprises the following steps of: receiving a control signal from the base station by the receiver of the mobile terminal, wherein the control signal is used for indicating a plurality of sub-carriers distributed for the terminal and used for transmitting service data; and judging whether the difference between the highest frequency FREHigh and the lowest frequency FRELow in the plurality of sub-carriers exceeds a threshold value THB, if not, receiving the service data by the receiver in a narrow-band mode, or else, receiving the data service in a broadband mode. According to the technical scheme provided by the invention, the signal bandwidth processed by the receiver can be narrowed, the digital sampling rate can be lowered, the calculated quantity and the relative storage of an FFT (Fast Fourier Transform) module can be reduced, and the effect of reducing power consumption of the mobile terminal can be further reduced.

Description

technical field

[0001] The present invention relates to the communication field, in particular to a service data transmission method, a receiver, a mobile terminal, a transmitter and a base station. Background technique

[0002] With the increasing demands of mobile communication users, high spectral efficiency is becoming one of the main requirements of mobile communication systems, and Orthogonal Frequency Division Multiplexing (OFDM) is just one of the main supporting physical layer technologies. The corresponding multi-user access technology in a multi-user environment is OFDMA, multiple mobile users can multiplex spectrum resources at the sub-carrier resource level, for example, the downlink of Long-Term Evolution (LTE) The road uses such OFDMA technology.

[0003] figure 1 Shows the block diagram of the wideband wireless OFDMA base station transmitter. The data of each user is coded and modulated, and the base station maps the signal to the broadband frequency band ...
