In the existing technology, the data transmitted between the mobile terminal and the base station based on full-duplex technology uses full duplex mode, that is, using the uplink frequency channel to transmit the data emitted from the mobile terminal to the base station, using the downlink frequency channel to transmit the data sent from the base station to the mobile terminal, the specific definition is as shown in FIG. 1a. According to the 3GPP standard, the frequency of the uplink frequency channel of the full duplex mobile terminal is lower than the frequency of the downlink frequency channel, that is, the uplink frequency channel is at the lower end of the frequency axis, and the downlink frequency channel is at the upper end of the frequency axis, there is a frequency guard band between the downlink frequency channel and the uplink frequency channel, to increase the isolation of emitting and receiving at the same time of the uplink and the downlink, decrease the mutual interference between emitting and receiving at the same time.

The uplink emitting the data and the downlink receiving the data of the full duplex mobile terminal can be performed at the same time, which is in full duplex mode, that is, the downlink frequency channel receives the data, while the uplink frequency channel emits the data at the same time, as shown in FIG. 1b, a diagram of the allocation of the frequency channel, wherein the full duplex mobile terminal can emit and receive at the same time. It can be seen from FIG. 1b, the uplink frequency channel and the downlink frequency channel can emit and receive the data at the same time, however, if the uplink frequency channel has no data to emit, then the frequency channel is idle, in this way, the uplink frequency channel is wasted, and the data amount received by the downlink frequency channel is usually larger, thus using full-duplex technology to transmit the data causes the low utilization of the frequency channel.

The present invention provides a wireless communication data transmission method, as shown in FIG. 2, the method includes:

S1, receiving a data sent from a base station to a mobile terminal with a downlink frequency channel by using full-duplex technology.

In the step, the traditional full-duplex technology is used, the downlink frequency channel is used to receive the data emitted from the base station, and transmit the data to the mobile terminal, and the downlink frequency channel is only used to receive the data emitted from the base station.

S2, emitting a data emitted from the mobile terminal to the base station, and receiving the data sent from the base station to the mobile terminal by using time division multiplexing technology through an uplink frequency channel.

But for the uplink frequency channel of the traditional full-duplex technology, then time division multiplexing is used to transmit the data, specifically, to allocate time duty cycles of emitting the data and receiving the data in the uplink frequency channel, according to a size of the data amount to be emitted. The data is emitted and received according to the allocated time duty cycle.

The uplink frequency channel of the traditional mobile station is used for the mobile station to emit the data to the base station, the aforementioned method is using the uplink frequency channel to receive the data emitted from the base station, when the uplink frequency channel of the mobile station is idle, and the uplink frequency channel of the mobile station is changed from receiving to emitting, when the mobile station emits the data, that is, the uplink frequency channel of the mobile station using time division multiplexing mobile station realizes that the mobile station uses the uplink frequency channel to emit and receive the data in divided time.

FIG. 3 illustrates a timing diagram of the uplink frequency channel of the specific embodiment of the method, the mobile station using the uplink frequency channel to emit and receive the data in divided time is realized through time division multiplexing. It can be seen from FIG. 3, when the downlink frequency channel of the mobile station receives the data, the uplink frequency channel of the mobile station can receive and emit the data in divided time, the uplink frequency channel is fully used.

Specifically, as shown in FIG. 4a-FIG. 4c, the uplink frequency channel of the mobile station uses time division multiplexing to receive the data sent from the base station, and to emit the data transmitted from the mobile terminal to the base station, the time duty cycle of receiving and emitting the data can be determined according to the emitted and received data amount. In the specific process of the embodiment, a data amount to be emitted from the mobile terminal to the base station is acquired first; then the time duty cycles of emitting the data and receiving the data in the uplink frequency channel are allocated, according to a size of the data amount to be emitted, wherein the time duty cycle of emitting the data in the uplink frequency channel is proportional to the data amount to be emitted, the time duty cycle of receiving the data in the uplink frequency channel equals to the time duty cycle of transmitting the data minus the time duty cycle of emitting the data in the uplink frequency channel.

In the specific transmission process, case 1, as depicted in FIG, 4a, when the emitted data amount is large, the duration of emitting is increased, and the duration of the receiving is decreased. Case 2, as shown in FIG. 4b, when the emitted data amount is small, the duration of the emitting is short, and the duration of the receiving is correspondingly extended. Case 3, as shown in FIG. 4c, if there is no data emitted during a period of time, then the uplink frequency channel can be used for receiving the data sent from the base station to the mobile terminal during the period of time.

Based on the aforementioned method, the present invention further provides a wireless communication data transmission system, as shown in FIG. 5, the system includes: the first control transmission module 110 and the second control transmission module 120.

The first control transmission module 110 is used for receiving a data sent from a base station to a mobile terminal with a downlink frequency channel by using full-duplex technology.

The second control transmission module 120 is used for using time division multiplexing technology, emitting a data emitted from the mobile terminal to the base station, and receiving the data sent from the base station to the mobile terminal by using time division multiplexing technology through the uplink frequency channel.
