Description
Technical Field
The application relates to the field of wireless transmission, in particular to a wireless transmission data packet length conversion system.
Background
Frequency division duplex, FDD, communication is one of the primary modes of wireless transmission. The FDD mode is characterized in that the wireless communication system receives and transmits on two separate symmetric frequency channels, and the reception and transmission channels are separated by a guard band.
The frequency division duplex communication adopts packet switching and other technologies, can break through the bottleneck of second generation development, realize high-speed data service, improve the frequency spectrum utilization rate and increase the system capacity. But frequency division duplex communication must employ paired frequencies, i.e. provide third generation services within a bandwidth of every 2x5 MHz. The method can fully utilize the uplink and downlink frequency spectrum when supporting symmetric service, but greatly reduces the frequency spectrum utilization rate when operating asymmetric packet switching (Internet) (about 40% of the frequency spectrum utilization rate is reduced due to low uplink load).
The application discloses a technical scheme of a frequency division duplex communication system and a method (application publication number: CN 111049632A), which comprises the following steps: at the wireless communication device, downlink data is received within a plurality of downlink subframes and a hybrid automatic repeat request acknowledgement message (HARQ-ACK) is sent on the uplink. The HARQ-ACK corresponds to downlink data received in at least two of the downlink subframes, and is transmitted in one uplink subframe.
The application discloses a technical scheme of a communication method (application publication number: CN 107294685A) when the TTI length of UL transmission and the TTI length of DL transmission are asymmetric, which comprises the following steps: determining at least one of a timing relationship between a downlink DL transmission and a corresponding uplink UL transmission and a timing relationship between a UL transmission and a corresponding DL transmission; performing at least one of UL transmission corresponding to the DL transmission and DL transmission corresponding to the UL transmission according to the determined timing relationship; wherein the transmission time interval, TTI, length of UL transmissions and the TTI length of DL transmissions in the frequency division duplex communication are set to be asymmetric.
In the actual use process of the frequency division duplex communication, a file or an image to be transmitted is generally divided uniformly to obtain multiple sub-data, each sub-data is packed into a data packet with a fixed packet length to obtain multiple data packets, and the multiple data packets are modulated onto a frequency division duplex communication channel successively to perform wireless transmission so as to complete wireless transmission of the file or the image.
Obviously, the above-mentioned transmission mechanism that is too solidified does not consider the characteristics of the object to be transmitted, for example, if the signal-to-noise ratio is low for a single picture to be transmitted wirelessly, and still uses a relatively long data packet for transmission, on one hand, error correction codes easily affect the error correction performance because of a large number of bits to be corrected, resulting in a decrease in error correction capability, and on the other hand, a relatively long data packet requires a relatively long transmission duration, resulting in a greater probability of introducing more channel interference under long-time transmission of the data packet, and further degrading the quality of the picture signal that is originally not high in signal-to-noise ratio.
Disclosure of Invention

wherein determining a wireless transmission data packet length in positive association with an overall signal-to-noise ratio corresponding to the single picture to be wirelessly transmitted for wireless transmission of the single picture to be wirelessly transmitted comprises: the lower the overall signal-to-noise ratio corresponding to the single picture to be wirelessly transmitted is, the shorter the determined wireless transmission data packet length positively correlated with the overall signal-to-noise ratio corresponding to the single picture to be wirelessly transmitted is.
The wireless transmission data packet length conversion system is intelligent in design and wide in application. On the basis of analyzing the overall signal-to-noise ratio of the single picture to be wirelessly transmitted by adopting a targeted analysis mechanism, the packet length of the data packet for wirelessly transmitting the single picture to be wirelessly transmitted is determined based on the overall signal-to-noise ratio obtained by analysis, so that the transmission speed and the transmission performance of wireless communication are both considered.
