In the third embodiment, the unlicensed channel 12 has been occupied by the femtocell 17 (the channel shown in the figure is busy), therefore, the data transmission network device 11 needs to wait for the unlicensed channel 12 to be vacant.

In the fourth embodiment, the unlicensed channel 12 has been occupied by the femtocell 17 (the channel shown in the figure is busy), therefore, the data transmission network device 11 needs to wait for the unlicensed channel 12 to be vacant.

Next, when the processor 111 of the data transmission network device 11 judges that the unauthorized channel 12 is in the unused state through the transceiver 113 in the standby area LBT4 of the transmitting end, in other words, after judging that the femtocell 17 has not used the unauthorized channel 12 , it can further transmit a transmitter channel reservation signal 114 in the unauthorized channel 12 through the transceiver 113, so as to notify the nearby related network devices (ie, the micro base station 17) that the unauthorized channel 12 has been used, and avoid other network devices ( That is, the femto base station 17) utilizes the unlicensed frequency channel 12.

On the other hand, after the transceiver 133 of the data receiving network device 13 receives the control message 110, the processor 131 judges whether the unauthorized channel 12 is in an unused state in the receiving end standby interval LBR4 according to the control message 110.

It must be emphasized again that in the foregoing embodiments, the data transmitting network device 11 is a base station, and the data receiving network device 13 is a mobile station, and mainly describes the anti-interference method of downlink data transmission, but those skilled in the art can easily understand through the foregoing content The role reversal of the two (that is, the data transmitting network device 11 is a mobile station, and the data receiving network device 13 is a base station) and the anti-interference method for uplink data transmission will not be repeated here.

It should also be noted that in the aforementioned embodiments, both the data transmitting network device 11 and the data receiving network device 13 have the function of transmitting and receiving data at the same time, which can be mainly accomplished by full-duplex radio (Full-Duplex Radio, FRD) technology, However, those skilled in the art should be able to understand from the foregoing disclosure that the technology of the present invention is based on the utilization of simultaneously transmitting and receiving data, rather than limiting the manner in which a device simultaneously transmits and receives data.

Please refer to FIGS. 5A-5C, which are schematic diagrams of an LAA network system 5 according to a fifth embodiment of the present invention. The data transmitting network device 11 is a first base station, and the data receiving network device 13 is a mobile station. The LAA network system 5 is more A second base station 19 is included. Wherein, the structure of the fifth embodiment is similar to that of the foregoing embodiments, so components with the same symbols have the same functions, and details are not repeated here. The fifth embodiment is mainly to describe the anti-jamming communication technology in more detail.

It should also be noted that in the fifth embodiment, the second base station 19 belongs to a first base station group GP1, and the data transmission network device 11 (ie, the first base station) belongs to a second base station group GP2. The first base station group GP1 further includes a third base station 18 . Wherein, a group can be regarded as a telecommunication operator. Therefore, according to known technologies, base stations under the same group have an agreement to coordinate channel usage with each other, which will not be repeated here.

First, before performing the method of occupying the unauthorized channel described in the foregoing embodiments, a preliminary configuration can be performed according to the channel usage status of the surrounding network devices. Specifically, in the fifth embodiment, the second base station 19 may first scan an unlicensed channel segment (Unlicensed Bands, not shown). Wherein, the unauthorized channel section includes the unauthorized channel 12 .

Then, the second base station 19 receives a first message 180 from the third base station 18 on the unlicensed channel 12, so that the second base station 19 can judge that in the unlicensed channel 12, the third base station 18 has already transmitted data transmission. Subsequently, the second base station 19 sends a second message 190 on the unlicensed channel 12 according to the first message 180 , so as to notify other base stations that the unlicensed channel 12 has been used by devices.

In this way, when the data transmission network device 11 (ie, the first base station) scans the unlicensed channel segment, the data transmission network device 11 (ie, the first base station) can receive the second message 190 in the unlicensed channel 12, and Based on this, it is known that the existing device uses the unauthorized channel 12 . Subsequently, the data sending network device 11 (ie, the first base station) can decide whether to select the unlicensed channel 12 to transmit data with the data receiving network device 13 (ie, the mobile station) according to the second message 190 .

Please refer to Figure 5B. For example, when the first message 180 and the second message 190 are physical layer signals, the data transmission network device 11 (ie, the first base station) can know that an existing device uses the unlicensed channel 12 according to the second message 190, and accordingly Another unlicensed channel 14 in the unlicensed channel section is selected to transmit data with the data receiving network device 13 (ie, the mobile station). In this way, interference is directly avoided.

On the other hand, the first message 180 and the second message 190 can be system information block (SystemInformationBlock) messages, and include a location information (not shown) and a channel usage information (not shown) of the third base station 18 . Wherein, the channel usage information indicates that the third base station 18 uses the unlicensed frequency channel 12 . In this way, the data transmission network device 11 (that is, the first base station) can directly know that the third base station 18 uses the unlicensed channel 12 according to the second message 190, and select another unlicensed channel in the unlicensed channel section accordingly. The authorized channel 14 transmits data with the data receiving network device 13 (ie, the mobile station).

However, it must be specifically stated that preferably, the data transmitting network device 11 (i.e. the first base station) should avoid using the unauthorized frequency channel 12 to transmit data with the data receiving network device 13 (i.e. the mobile station), so as to reduce the third base station 18's concern for data. Interference that may be generated by the network device 13 (ie, the mobile station) is received. However, when the number of devices is too large, the supply of unauthorized channels will exceed the demand. Therefore, it is still possible to select unauthorized channels that have already been used.

Please refer to FIG. 5C, when there is no free unlicensed channel available in the unlicensed channel segment, the data transfer network device 11 (i.e., the first base station) can, according to the location information of the third base station 18 in the second message 190, It is determined that the distance between the third base station 18 and itself exceeds a preset threshold (the longer the distance, the lower the possibility of interference).

In this way, when the data transmission network device 11 (ie, the first base station) has a considerable distance from the third base station 18, it means that the probability of interference between the third base station 18 and the data transmission network device 11 (ie, the first base station) is relatively low. Low, therefore, the data transmitting network device 11 (ie, the first base station) can select the unlicensed channel 12 used by the third base station 18 to transmit data with the data receiving network device 13 (ie, the mobile station). And when there is a situation of repeated use of unauthorized channels, the method of the above-mentioned embodiment can be used for coordination, which will not be repeated here.

Please refer to FIGS. 6A-6C , which are schematic diagrams of an LAA network system 6 according to a sixth embodiment of the present invention. Wherein, the structure of the sixth embodiment is similar to that of the foregoing embodiments, so components with the same symbols have the same functions, and details are not repeated here. The sixth embodiment mainly illustrates another implementation aspect of the anti-jamming communication technology.

Likewise, before performing the method of occupying the unauthorized channel described in the foregoing embodiments, a preliminary configuration can be performed according to the channel usage status of the surrounding network devices. In the sixth embodiment, the data transmission network device 11 (ie, the first base station) directly retrieves a base station information DBinfo from a base station status database DB. The base station information DBinfo records location information (not shown) and channel usage information (not shown) of the third base station 18 , and the channel usage information records that the third base station 18 uses the unauthorized channel 12 to transmit data.

In this way, the data transmission network device 11 (that is, the first base station) can directly judge according to the base station information DBinfo that there is already a third base station 18 for data transmission in the unauthorized channel 12, and decide whether to select the unauthorized channel 12 accordingly.
