TECHNICAL FIELD

The present application relates to the field of communications, and in particular, to a data segmentation method, a data segmentation apparatus, and a data segmentation terminal.

BACKGROUND

In mobile communication systems, due to the time-varying characteristics of wireless fading channels, there is significant uncertainty in the communication process. In order to improve the throughput of the system, high-order modulation with a high transmission rate and less redundant error correction codes can be used for communication, so that when the signal-to-noise ratio of the wireless fading channel is ideal, the throughput of the system can be greatly improved, but when the channel is in deep fading, it cannot be ensured to perform communication reliably and stably. In addition, in order to ensure the reliability of communication, low-order modulation with a low transmission rate and large redundant error correction codes can be used for communication, that is, to ensure that the communication is reliably and stably performed when the wireless channel is in deep fading. However, when the signal-to-noise ratio of the channel is relatively high, the transmission rate is rather low, it may limit the improvement of the throughput of the system, and cause waste of resources. In the early development of mobile communication technology, people can only resist against the time-varying characteristics of wireless fading channels, and can only guarantee the communication quality of the system during deep fading of the channel by increasing the transmission power of the transmitter and employing a modulation coding method with low-order and large redundancy, and cannot consider how to improve the throughput of the system. With the advancement of the technology, there has been a technology that can adaptively adjust its transmission power, a modulation and coding scheme and a frame length of data according to the channel state to overcome the time-varying characteristics of the channel, thereby obtaining the best communication effect, which is called self adaptive code modulation technology and belongs to the most typical link adaptation technology.
