Description

transmission device, system and method based on frequency hopping

Technical Field

the present invention relates to the field of wireless communications technologies, and in particular, to a transmission device, system, and method based on frequency hopping.

background

with the rapid expansion of Machine-to-Machine (M2M) communication applications, market demands and scale have seen explosive growth in recent years. The M2M communication system may adopt the form of co-frequency networking or inter-frequency networking during spectrum planning. The same-frequency networking refers to sharing of the same section of frequency spectrum resources among different cells; inter-frequency networking refers to neighboring cells each using different frequency resources. Due to the requirements of the M2M market application for deep coverage performance, low power consumption, and the like, the use of narrow bandwidth for data communication becomes an extremely effective technical means. From the aspect of spectrum resource utilization, for M2M communication, the requirement of a narrow bandwidth scene is better met by adopting a same-frequency networking mode. Furthermore, in order to meet the requirements of the application of M2M communication on the coverage performance, the signal is usually repeatedly transmitted in the time domain. At this time, the coverage performance is improved by the energy accumulation of the repeated signals at the receiving end. However, in the same-frequency networking mode, because frequency spectrum resources are shared among cells, the interference of neighboring cells may also be accumulated while the receiving end accumulates signal energy. Therefore, how to reduce the interference between different cells of the same-frequency networking becomes especially important.

For the interference elimination mechanism among cells in the same-frequency networking mode, the prior art scrambles and interleaves signals by adopting different scrambling codes and interleaving patterns aiming at different cells. However, the prior art has certain randomness, and the effect of interference cancellation is influenced by many random factors such as relative time delay among cells, and particularly in a communication system with signal repetition, the influence may be amplified along with the repetition. Therefore, the quality of signal transmission in the same-frequency networking mode is reduced.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

in view of the above-mentioned problems in the prior art, the following embodiments of the present invention provide a transmission scheme based on frequency hopping, and the purpose of the transmission scheme is as follows: in a same-frequency networking mode, for any two cells sharing spectrum resources, in any continuous N frequency hopping periods during one data transmission period, the number of times of conflict of using frequency points of sending end equipment in the two cells is at most 1, wherein N is the number of available frequency points of any one cell in the two cells, and the available frequency points are all frequency points in a frequency band range which can be used by the sending end equipment in the cell.

fig. 1 is a schematic deployment diagram of a transmission system based on frequency hopping according to an embodiment of the present invention, where the system may include a plurality of communication networks, such as a wide area network (wireless mobile communication network, satellite communication network, internet, etc.), a local area network (ethernet, wireless local area network, bluetooth, etc.), a personal area network (zigbee protocol network, sensor network, etc.).

referring to fig. 1, the system includes: cell 1, cell 2, cell 3; a sending terminal device 1, a sending terminal device 2, and a sending terminal device 3; the system comprises a receiving end device 1, a receiving end device 2 and a receiving end device 3;

It should be noted that cells 1 to 3 share spectrum resources, and the transmitting end device 1 and the receiving end device 1 are located in the cell 1; the sending end device 2 and the receiving end device 2 are in a cell 2; the sending end device 3 and the receiving end device 3 are in a cell 3;

the sending end device may be a user device, such as a smart phone, a tablet computer, a vehicle-mounted communication device, and the like; or may be an access device, such as a base station, an evolved base station, a hotspot device, a relay device, and the like.

Similarly, the receiving end device may be a user device, for example, a smart phone, a tablet computer, a vehicle-mounted communication device, or the like; or may be an access device, such as a base station, an evolved base station, a hotspot device, a relay device, and the like.

Further, the scheme provided by the present invention is described by taking the deployment scenario of fig. 1 as an example. Firstly, taking the sending end device 1 of the cell 1 as an example, the sending end device 1 numbers available frequency points that can be used, for example, five frequency points are respectively numbered as {0, 1, 2, 3, 4 }; the embodiment of the invention does not limit the specific rule of the frequency point number, as long as the frequency point number can be ensured to be a continuous natural number; and the sending end equipment 1 maps the frequency point numbers to the available frequency points and establishes a one-to-one corresponding relation. Similarly, the sending-end device 2 and the sending-end device 3 perform similar processing. Optionally, the numbering process of the available frequency points may also be completed by the network control device, and the frequency point numbers and the mapping relationship with the frequency points are directly sent to the sending end device. It should be noted that the frequency point numbers are usually consistent for different cells.

further, taking the sending end device 1 and the sending end device 2 as an example for explanation, the sending end device 1 obtains the initial frequency point used in the first frequency hopping period. Optionally, the initial frequency point may be obtained by calculation of the sending end device 1, or obtained by a preset table entry, or obtained by receiving a signaling message sent by the network control device. The sending end device 2 also obtains the initial frequency point used in the first frequency hopping period. It should be noted that the initial frequency obtained by the sending end device 1 may be the same as or different from the initial frequency obtained by the sending end device 2.

Further, the transmitting-end device 1 obtains the frequency hopping interval value Δ₁similarly, the transmitting-end device 2 obtains the frequency hopping interval value Δ₂in order to achieve the effect that the number of times of collision of the frequency points used by the sending end devices in the two cells is at most 1, Δ is set₁and delta₂The absolute value of the difference is relatively prime to the number of available frequency points. Transmitting end equipment 1 according to delta₁And the initial frequency point performs frequency hopping processing on the frequency points used in each frequency hopping period, and continues to perform the frequency hopping processing on the five frequency points as the example, if the initial frequency point of the sending end device 1 is 0, delta is₁if the frequency point number is 1, the frequency point numbers corresponding to the frequency points used by the sending end device 1 in five frequency hopping periods are in the following order: 0, 1, 2, 3, 4; if the initial frequency point of the sending end device 2 is 0, delta₂for 2, the sequence of the frequency point numbers corresponding to the frequency points used by the sending end device 2 is: 0. 2, 4, 1, 3; it can be seen that due to Δ₂And delta₁The absolute value of the difference is 1, and 1 and 5 are relatively prime, so that for the sending end device 1 and the sending end device 2, only the conflicting frequency points are the initial frequency points, that is, the frequency points with the frequency point number of 0. Therefore, the effect that the number of times of conflict of the use frequency points of the sending end equipment in the two cells is at most 1 time is realized.

in addition, if the initial frequency points used by the sending end device 1 and the sending end device 2 are different, then the occurrence of collision can be completely avoided. For example, the sequence of the frequency point numbers corresponding to the frequency points used by the sending end device 1 still is: 0, 1, 2, 3, 4; at this time, the initial frequency point of the sending end device 1 is 2, Δ₂and 2, the sequence of the frequency point numbers corresponding to the frequency points used by the sending end device 2 is: 2. 4, 1, 3, 0; it can be seen that the sending end device 1 and the sending end device 2 completely avoid the conflict of using frequency points.

It should be noted that the sending end device 1 and the sending end device 3, and the sending end device 2 and the sending end device 3 may all adopt the above-mentioned manner to avoid conflicts when using frequency points. The above system only takes three cells, three sending end devices and three receiving end devices as an example for explanation.

optionally, how to determine the frequency point number corresponding to the frequency point of each frequency hopping period by the sending end device may have multiple implementation manners, and a feasible implementation manner is given below for description. Taking a sending terminal device as an example, the sending terminal device is located in a first cell, and a second cell is any cell sharing spectrum resources with a cell to which the sending terminal device belongs; the frequency point number corresponding to the frequency point of each frequency hopping period can be obtained by the following formula:

index_i+1＝(index_i+Δ)mod N

Wherein the index_i+1The frequency point number corresponding to the frequency point of the (i + 1) th frequency hopping period, the index_iNumbering frequency points corresponding to the frequency points of the ith frequency hopping period, wherein delta is the frequency hopping interval value of the first cell, and delta is a positive integer; and the absolute value of the difference between the frequency hopping interval value of the first cell and the frequency hopping interval value of the second cell is relatively prime to N. The i is a natural number greater than or equal to 1; index₁And numbering the frequency points corresponding to the initial frequency points used by the sending end equipment in the first frequency hopping period.

it should be noted that the above formula is only a specific implementation form, and the final purpose is to ensure that when the sending end devices of different cells perform frequency hopping processing, the change intervals of corresponding frequency point numbers are the same and are specific to the sending end device of each cell, so that implementation manners that can meet such requirements all belong to the protection scope of the present invention.

In summary, the scheme provided by the embodiment of the present invention can reduce inter-cell interference to the greatest extent, especially when the signal has repetition in the time domain. Specifically, in order to enable the transmitted signal to cover some far or more biased environments, the signal needs to be repeatedly transmitted in the time domain to improve the signal-to-noise ratio when the signal arrives, fig. 9 is a schematic diagram of the repetition of the time domain position provided by the embodiment of the present invention, referring to fig. 9, a piece of data is repeatedly transmitted in the time domain N times (for convenience of analysis, the repetition times are not set to be equal to the number of available frequency points), the signal-to-noise ratio of the received signal can be improved by the receiving end device performing coherent combination on the repeated data, and in an ideal state, the signal-to-noise ratio can be improved by₁₀n dB, due toFor the purpose of combining, the signal power is increased by N²and the Gaussian noise power is improved by N times.

Considering that there is interference, that is, there is data repeatedly transmitted N times in a second cell sharing spectrum resources with a first cell, assuming that a signal and the interference overlap in a time domain, fig. 10 is a schematic diagram of overlapping of the signal and the interference in the time domain, and referring to fig. 10, a shaded portion represents the interference. Assuming that the interference power is the same as the signal power, the interference is the most severe when the signal completely collides with the frequency used by the interference at each repetition position. At this time, let s be the signal and interference power, n be the noise, and the signal-to-interference ratio after the received signals are combined benamely, the interference energy in the received signal is the same as the signal energy, and the interference is serious; when the frequency points used by the signal and the interference at each repeated position are different, namely in an ideal state, no interference exists, and the signal-to-noise ratio is equal to the signal-to-noise ratio of

for the scenario shown in fig. 10, when the above scheme of the present invention is adopted, that is, the cells use equal-interval frequency hopping, the absolute value of the difference between the frequency hopping interval value of the first cell and the frequency hopping interval value of the second cell is relatively prime with the number of available frequency points, and the frequency hopping period is the repetition time of the repetition position of one data, that is, the duration of one data block in fig. 10.

Therefore, in the scenario shown in fig. 10, all N frequency points are used for signal and interference, and the use time of each frequency point is the duration of a repeat position of one data, fig. 11 is a schematic frequency hopping diagram provided in the embodiment of the present invention, and refer to fig. 11. The interference size depends on the number of frequency points of the signal and interference conflict.

It can be proved that the number of the frequency points of the two cells where the conflict occurs is: the absolute value of the difference between the frequency hopping interval value of the first cell and the frequency hopping interval value of the second cell and the greatest common divisor of the numerical values N of the available frequency points. That is, the number k of frequency points where two cells collide is equal to (| Δ ═ Δ |)₁-Δ₂l, N), whichmiddle delta₁、Δ₂the hop interval value used for both cells. And this equation is not affected by the take-off position, i.e. when the signal and interference use any frequency point from 0 to N-1 at the repetition position 0 using the frequency point u0, the above equation holds.

According to the embodiment of the invention, when the absolute value of the difference between the frequency hopping interval values of different cells and the number of available frequency points are relatively prime, namely the greatest common divisor k is equal to 1, namely the interference collides with the frequency point of at most one repetition position of the signal in N repetition positions, in other words, when the receiving end equipment carries out signal combination, the signal can complete energy accumulation, and the interference is randomized. When there is a cell interference of an equal power shared spectrum resource, the theoretical signal-to-interference-plus-noise ratio is

It should be noted that the anti-interference performance achieved by the scheme provided by the embodiment of the present invention is assumed that the number of signal repetitions is equal to the number N of frequency points. In fact, at this time, the performance achieved by the scheme is the optimal performance, that is, the number 1 of the coincident frequency points of the signal and the interference is the minimum. But the signal and the interference cannot coincide with each other. In an actual system, relative time delay exists among cells, and more than or equal to 1 superposed frequency point is inevitable. If the signal repetition times r is greater than the frequency point number N, the scheme ensures that the number of the coincident frequency points of the signal and the interference is not greater than the number of the coincident frequency points of the signal and the interference in r repeated resettingis the best performance that can be achieved. If the signal repetition times r is less than the number N of the available frequency points, the scheme ensures that the number of the superposed frequency points of the signals and the interference is not more than 1 in r repeated resetting processes, and the optimal performance can be achieved.

for example, referring to the same-frequency networking mode with three cells sharing spectrum resources in fig. 1, if N is 7, the interval value of 3 cells may be selected from {1, 2, 3, 4, 5, 6}, and it is only necessary to ensure that the frequency hopping interval values of different cells are different, which may be implemented by binding the frequency hopping interval value with the identifier of the cell.

In addition, m cells are set to share the N available frequency points, that is, each cell may use any one of the N frequency points at a certain time. At this time, in order to ensure that the time when the hopping pattern of different cells "hits" is minimum, the m cells are required to transmit data by using the above-mentioned equal-interval hopping method, and at the same time, the following requirements are met between any two cells: and the absolute value of the difference between the frequency hopping interval value of the first cell and the frequency hopping interval value of the second cell is relatively prime to N. Let the interval values of m cells be respectively delta₁，Δ₂，...，Δ_mI.e. the following equation needs to be satisfied. In addition, each interval value Δ needs to be relatively prime with N.

(|Δ_i-Δ_j|，N)＝1，(i≠j，i，j＝1，...，m)

in addition. For the solution provided in the embodiment of the present invention, if N is a prime number, implementation is easy, for example, a same-frequency networking including three cells, where N is 11, and the interval value of the three cells may take any one of 1 to 10; however, if N is a number with a large divisor, for example, 8, the co-prime constraint is not necessarily satisfied, for example, in the co-frequency networking of three cells, N is 8, and 3 different integers cannot be found, so that the absolute value of the difference between the hopping interval values of any two cells is co-prime with N. At this time, there are two solutions, first, some performance is sacrificed, i.e. the absolute value of the difference between the hopping interval values of any two cells and the greatest common divisor of N may not be 1, but 2, 3, etc.; secondly, searching for the maximum prime number in integers smaller than N, for example, when N is 8, the design is not easy, the frequency hopping scheme of the above embodiment is performed on 7 channels, so that the frequency hopping of the cell to which the transmitting end device belongs in the 7 channels is guaranteed to have good anti-interference performance, and then, for the remaining 1 channel, the cell can be shared and designed by using the anti-interference technology in the prior art, for example, scrambling, interleaving, spreading and the like of the cell characteristics are performed.

In the following, a scenario that N is not a prime number is described by a specific embodiment, and how the transmission method based on frequency hopping provided by the embodiment of the present invention is implemented is described.

optionally, the receiving end device determines the frequency point number corresponding to the frequency point of the frequency hopping period according to the frequency point number, and obtains the frequency point number through the following formula:

index_i+1＝(index_i+Δ)mod M

wherein M is the maximum prime number not greater than the number N of the available frequency points;

Further, the sending end device performs anti-interference processing on the data carried at the N-M frequency points by using scrambling codes and/or interleaving patterns for the remaining N-M frequency points.
