Description

Technical Field

[0001] The present invention relates to the technical field of multi-antenna communications, and in particular to a communication method, device, and medium based on multi-antenna discrete narrowband aggregation. Background Art

[0002] For communications in certain industries, spectrum resources are fixed, narrow, and discrete. Conventional transmission systems use continuous bandwidth for broadband services, making it difficult to utilize the discrete spectrum resources allocated to certain industries. Existing discrete narrowband communication systems can only support low-rate services. Using continuous bandwidth for service transmission is likely to interfere with spectrum resources allocated to other industries.

[0003] Existing broadband transmission systems based on discrete narrowband aggregation are suitable for narrowband planned frequency bands. They can flexibly aggregate narrowband resources and achieve broadband transmission without changing existing frequency usage, thus meeting the industry's broadband service needs. However, they lack reliable downlink reception and result in low transmission resource utilization.

[0004] For example, a Chinese patent document titled "A Communication Method and Apparatus," published under the publication number CN109275190A, discloses a method that includes sending a first indication to a terminal to determine the frequencies of all discrete subbands in a cell; the terminal then receives a second indication to determine the available subbands within the discrete subbands. This solution also suffers from issues such as a lack of downlink reception reliability and low transmission resource utilization. Summary of the Invention

[0005] In order to solve the problems of low transmission resource utilization and poor downlink reception reliability in narrowband aggregation in the prior art, the present invention provides a communication method, device and medium based on discrete narrowband aggregation with multiple antennas, which improves transmission resource utilization through alternating communication of multiple antennas and improves downlink reception reliability through multi-signal determination communication.

[0006] In order to achieve the above object, the present invention provides the following technical solutions:

[0007] A communication method based on discrete narrowband aggregation using multiple antennas includes the following steps: a first antenna transmits a first signal, the first signal providing availability information; a second antenna transmits a second signal, the second signal providing second availability information; a third antenna receives a third signal, the third signal including occupancy information; the second signal is transmitted after receiving the third signal; and the second signal is determined by the first and third signals. Multiple nodes are divided into communication resources based on signal source characteristics, and an on / off signal is set for each node to determine whether the node is occupied. The node number is prepended to the on / off signal to obtain a code for the communication resource; the on / off signal at the end of the communication resource code is reviewed to determine availability information, and the availability information and a first time are transmitted to a terminal as a first signal. The received narrowband signals are aggregated into communication resources, which communicate the narrowband signals through different nodes, indicating that the on / off signal status of the node receiving narrowband communication is busy. Upon receiving the third signal, the occupancy information indicates that the on / off signal of the desired node is busy. The remaining nodes that are not busy are reviewed and the remaining nodes and the second time are sent as the second available information. After receiving the first signal and the second signal, the terminal sends a third signal. The communication resources can be utilized simultaneously through multiple antennas, which can improve the reliability of downlink reception.

[0008] Preferably, the first antenna is located at a transmission node, and transmitting the first signal includes counting available communication resources and transmitting the available communication resources along with modulation information. The transmission node is provided with a communication resource library, which includes multiple subbands. Each subband includes a first transmission area and a second transmission area, with an isolation interval between the first and second transmission areas. When both the first and second transmission areas are occupied, the on / off signal of the node in the subband indicates busy. The first and second transmission areas are of fixed length, and the subband includes multiple subframes, which are sequentially arranged within the first and second transmission areas. The isolation interval is located within a subframe, and the subframe containing the isolation interval is connected to the first, isolation, and second transmission areas simultaneously. When the on / off signal is within the isolation interval within a subframe, the state is indicated as unblocked. When the on / off signal is within the first or second transmission area within a subframe, the state is indicated as busy. Subbands with unblocked on / off signals are designated as available communication resources, and the available communication resources and corresponding modulation information are transmitted to the terminal as the first signal. This provides information on available communication resources for narrowband aggregation communication.

[0009] Preferably, the second antenna is located at the transmission node. The second signal is sent after the first signal is sent and after the third signal and after the third signal is received. The second available information includes the modified communication resources and modulation information. The transmission node is connected to a communication resource library, which is connected to both the first and second antennas. The first antenna is used to provide available communication resources to the terminal, while the second antenna is used to provide the terminal with real-time available communication resources. The first antenna reviews the on / off signal, while the second antenna reviews the isolation interval. The first antenna packages and transmits all available modulation information, while the second antenna transmits the modulation information for the optimal subband. After the third antenna receives the third signal, the second antenna again reviews available subbands, with the review criteria including reviewing the length of the second transmission zone. This re-review of communication resources before downlink signal transmission and transmission to the terminal improves communication efficiency.

[0010] Preferably, the third antenna is located at the transmission node, and the third signal is received after the first signal is transmitted. The occupancy information includes communication resource demand information. The third antenna, along with the first and second antennas, is located on the transmission node simultaneously. The demand information includes communication information and a second permission signal. The second permission signal is an admission mark after the terminal receives the second signal. This admission mark is transmitted to the terminal via the second signal and then returned to the transmission node via the third signal. The second permission signal shifts the on / off signal within the subframe. The duration of the second permission signal is controlled by a timer. The second permission signal disappears after the communication ends, equal to the difference between the first time and the second time. The second permission signal provides a transient shift instruction for the on / off signal. The transient shift instruction disappears after the second permission signal disappears, and the on / off signal returns to the isolation interval. This ensures the transmission reliability of downlink signals.

[0011] Preferably, the third signal is transmitted by a terminal, and the second signal is received and the third signal is transmitted at different terminals. The terminal transmits the third signal while simultaneously transmitting the communication information. After communicating with the first antenna, the terminal communicates with the third antenna, and finally connects with the second antenna to complete the communication. This allows the terminal to connect to different antennas to represent different communication progress, segmenting the communication process and performing it through different antennas. This allows multi-terminal communication to be controlled and performed independently by each terminal, allowing the transmission node to use different locations of communication resources through different antennas, thereby improving communication efficiency, processing efficiency, and communication reliability.

[0012] Preferably, determining the second signal includes adding the isolation interval to the third signal and subtracting the added result from the first signal; the second signal and the first signal each acquire and modulate communication resources. The communication resource requirement information includes the required length of the second transmission zone; the length of the isolation interval and the required length of the second transmission zone are added together, and the result of the addition is used as the target position of the transient movement instruction; the first signal acquires the status indication of the on-off signal, which is located at the beginning of the first transmission zone, while the subband coding is located within the first transmission zone, and the length information of the second transmission zone is located within the first transmission zone; the second signal acquires the position of the on-off signal within the isolation interval; the modulation information is information that allows devices with the same modulation information to connect during operation. The first and second signals can be used to separately process information at different locations of the communication resource, thereby improving resource utilization.

[0013] A communication device based on discrete narrowband aggregation of multiple antennas includes a processor, a storage medium, and a computer program. When executed, the computer program implements the aforementioned communication method based on discrete narrowband aggregation of multiple antennas. The processor is connected to the storage medium and includes a multifunctional processor. The computer program is located in the multifunctional processor or the storage medium, and the program is executed through the combination of the processor and the storage medium.

[0014] A computer-readable storage medium stores a computer program that, when executed by a processor, implements the aforementioned communication method based on discrete narrowband aggregation of multiple antennas. This method can be implemented by executing the computer-readable storage medium, or by another processor reading and executing the program from the computer-readable storage medium. The program implementing this method can be transferred and executed to achieve mobile operation.

[0015] The present invention has the following advantages:

[0016] (1) Improve the utilization rate of transmission resources through multi-antenna alternating communication, and improve the reliability of downlink reception through multi-signal determination communication; (2) Real-time update of available communication resources in narrowband transmission through multiple antennas, and improve the efficiency of narrowband aggregation communication by utilizing information at different locations in the communication resources; (3) Change the status of communication resources through transient movement instructions, reduce the tediousness of re-detection of communication resources, and improve communication efficiency.

[0023] The following describes the implementation methods of the present invention through specific embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection of the present invention.

[0024] like Figure 1 As shown, in a preferred embodiment, the present invention discloses a communication method based on discrete narrowband aggregation of multiple antennas, including the following steps: the first antenna sends a first signal, and the first signal is used to provide available information; the first antenna is located at a transmission node, and the transmission of the first signal includes counting available communication resources, and sending the available communication resources and modulation information together. A transmission node is connected to a communication resource library, which includes multiple subbands 5. Each subband 5 has a first transmission area 6 and a second transmission area 7, with an isolation interval 8 between them. When both the first transmission area 6 and the second transmission area 7 are occupied, the on / off signal of the node in that subband is considered busy. The first transmission area 6 and the second transmission area 7 are of fixed length. Subband 5 has multiple consecutive subframes 9, which are sequentially arranged within the first transmission area 6 and the second transmission area 7. The isolation interval 8 is located within a subframe 9. The subframe 9 containing the isolation interval 8 is connected to the first transmission area 6, the isolation interval 8, and the second transmission area 7 simultaneously. When the on / off signal is within the isolation interval 8 within a subframe 9, the state is considered unblocked. When the on / off signal is within the first transmission area 6 or the second transmission area 7 within a subframe 9, the state is considered busy. Subbands with unblocked on / off signals are considered available communication resources, and the available communication resources and corresponding modulation information are sent to the terminal as a first signal.

[0025] When in use, the transmission node sends the first signal to the first terminal through the first antenna. At the same time, the transmission node is also connected to other terminals through other antennas. The communication resources are stored in the communication resource library as a mapping relationship, and the transmission node processes the first signal and channel through the mapping relationship.

[0026] The second antenna transmits a second signal, which provides second available information. Determining the second signal includes adding the isolation interval to the third signal and subtracting the added result from the first signal. The second antenna is located at the transmission node, and the second signal is transmitted after the first signal is transmitted and after the third signal is received. The second available information includes modified communication resources and modulation information. A communication resource library is provided within the transmission node, connected to both the first and second antennas. The first antenna provides available communication resources to the terminal, while the second antenna provides real-time available communication resources to the terminal. The first antenna reviews the on / off signal, while the second antenna reviews the isolation interval. The first antenna packages and transmits all available modulation information, while the second antenna transmits the modulation information for the optimal subband. After receiving the third signal from the third antenna, the second antenna again reviews the available subbands, using criteria including the length of the second transmission zone.

[0027] During use, the transmitting node determines whether it has received the third signal. After determining that the third signal has been received, the transmitting node uses communication resources based on the information carried by the third signal. The transmitting node uses the built-in processing module of the second antenna to screen subbands that meet the requirements of the third signal. Communication is then carried out using the modulation information sent by the first signal.

[0028] The third antenna receives a third signal, which includes occupancy information. The second signal is transmitted after receiving the third signal. The second signal is determined by the first and third signals. The third antenna is located at the transmission node, and the third signal is received after the first signal is transmitted. The occupancy information includes communication resource demand information. The third antenna, along with the first and second antennas, is located at the transmission node. The demand information includes communication information and a second grant signal. The second grant signal is an admission tag issued by the terminal after receiving the second signal. This admission tag reaches the terminal via the second signal and then returns to the transmission node via the third signal. The second grant signal shifts the on / off signal within the subframe. The duration of the second grant signal is controlled by a timer. The second grant signal disappears after the communication ends, equal to the difference between the first time and the second time. The second grant signal provides a transient shift instruction for the on / off signal. The transient shift instruction disappears after the second grant signal disappears, at which point the on / off signal returns to the isolation interval.

[0029] When in use, the second antenna sends a second grant signal to the first terminal, and the first terminal converts the second grant signal into a grant tag and adds the tag to the third signal.

[0030] The third signal is sent by the terminal, the receiving of the second signal and the sending of the third signal are located in different terminals, and the terminal sends the third signal while sending the communication information. The terminal communicates with the first antenna, then communicates with the third antenna, and finally communicates with the second antenna to complete the communication. The terminal can be connected to different antennas to represent different communication progress, and the communication process is divided into different segments through different antennas, which realizes the control and implementation of each terminal in multi-terminal communication, so that the transmission node can use different positions of the communication resource through different antennas.

[0031] In use, the transmission node obtains the third signal from the second terminal through the third antenna, before which the transmission node sends the second signal to the second terminal through the second antenna, and after the transmission node obtains the third signal from the second terminal, the transmission node sends the second signal to the first terminal through the second antenna. Thus, different progress communication of multiple devices is realized.

[0032] The second signal and the first signal obtain communication resources and are modulated respectively. The demand information of the communication resource includes the demand second transmission zone length, the length of the isolation zone interval is added to the demand second transmission zone length, and the addition result is taken as the target position of the transient movement instruction; the first signal obtains the state representation of the on-off signal, the state representation of the on-off signal is located at the beginning of the first transmission zone 6, and the sub-band coding is located in the first transmission zone 6, and the length information of the second transmission zone 7 is located in the first transmission zone 6; the second signal obtains the position of the on-off signal in the isolation zone interval; and the modulation information is information for connecting devices with the same modulation information during work.

[0033] A communication device based on multi-antenna time discrete narrowband aggregation includes a processor 1, a storage medium 2, and a computer program 3. When the computer program 3 is executed, the above-mentioned communication method based on multi-antenna time discrete narrowband aggregation is realized. The processor 1 is connected with the storage medium 2, the processor 1 includes a multifunctional processor, the computer program 3 is located in the multifunctional processor or the storage medium 2, and the running of the program is realized through the combination of the processor 1 and the storage medium 2.

[0034] In use, the processor 1 is connected with a communication bus 4 or a wireless signal transmitter, and the processor 1 communicates in the above-mentioned mode according to the program.

[0035] A computer readable storage medium has a computer program stored thereon. When the computer program is executed by a processor, the above-mentioned communication method based on multi-antenna time discrete narrowband aggregation is realized. The method can be realized by running the computer readable storage medium, or by reading and running the program in the computer readable storage medium through other processors. The program that can realize the method can be transferred and run to realize mobile operation.

[0036] When in use, the readable storage medium stores a program that can implement the method, and the method can be implemented by connecting the readable storage medium to a communication bus or a wireless signal transmitter.

[0037] In the second embodiment, a reference signal is obtained before the first signal is transmitted. Communication resources are screened based on the reference signal, which includes characteristic information of the information to be transmitted. Communication resources matching this characteristic are selected, and unobstructed subband 5 is also selected within these matching communication resources. In use, a transmitting node is connected to multiple subbands, and narrowband aggregation transmission is achieved by combining these multiple subbands.

[0038] In a third embodiment, subband data is fused into node numbers, and the node numbers and on / off signals are combined to form a communication resource code. Multiple nodes are divided within the communication resource based on signal source characteristics, and an on / off signal is set for each node. The on / off signal is used to determine whether the node is occupied. The node number is prepended to the on / off signal to obtain the communication resource code. The on / off signal at the end of the communication resource code is reviewed to determine availability information, and the availability information and the first time are sent to the terminal as a first signal. Received narrowband signals are aggregated into the communication resource, which communicates the narrowband signals through different nodes. The on / off signal status of the nodes receiving narrowband communication is indicated as busy. Upon receiving the third signal, the occupancy information indicates that the on / off signal of the desired node is busy. The remaining nodes that are not busy are reviewed, and the remaining nodes and the second time are sent as the second availability information. After receiving the first and second signals, the terminal transmits the third signal.

[0039] When in use, the transmission node manages multiple narrowbands by numbering, and the first antenna judges the on / off signal at the communication resource encoding location, but does not judge the on / off signal at the front end of the first transmission area.

[0040] Although the present invention has been described in detail above using general descriptions and specific embodiments, it will be apparent to those skilled in the art that modifications and improvements may be made thereto. Therefore, such modifications and improvements, without departing from the spirit of the present invention, are intended to be within the scope of protection claimed herein.
