Description

Frequency hopping method and device for multi-hop network

Technical field

This application relates to the field of wireless communication technology, and in particular to a frequency hopping method and device for a multi-hop network.

Background technique

Frequency-hopping spread spectrum (FHSS) is a kind of spread spectrum technology, which refers to a technology in which both ends of a signal send and receive signals simultaneously and synchronously using a narrow-band carrier whose carrier frequency is constantly hopping. Frequency hopping technology is mainly used in military communications, which can effectively resist interference and exert communication efficiency.

In frequency hopping transmission, the hopping of the carrier frequency is controlled by a pseudo-random code. Specifically, the signal sending end is under the control of the clock, the pseudo-random sequence generated by the continuous change of the pseudo-random code to control the continuous change of the carrier frequency generated by the control frequency synthesizer of the transmitter, forming a time-varying frequency hopping Carrier series (also called frequency hopping pattern); at the receiving end of the signal, the receiving frequency of the receiver's frequency synthesizer is also controlled by the pseudo-random code, then, if the frequency hopping carrier series received by the receiver and the receiver If the generated frequency hopping patterns are consistent, the signal can be effectively output after demodulation.

Figure 1 is a schematic diagram of frequency hopping transmission and narrowband interference in a current multi-hop network. As shown in Figure 1, at present, the cell-level frequency hopping scheme is commonly used in multi-hop networks. In the cell-level frequency hopping scheme, node equipment and its sub-link devices use the available carrier resources of the sub-link to perform Frequency hopping. However, in a multi-hop network, sub-links can usually only be allocated a few available frequency resources by the base station. For example, the available frequency resources of the three relay nodes T0, T1, and T2 shown in Figure 1 are P0, P1 and P2, when narrowband interference occurs, because the available frequency resources of the relay node are less, the frequency hopping range of the relay node's sub-links is very small, and the narrowband interference cannot be effectively resisted, especially when the narrowband interference appears in more With more frequency points, the resistance to narrowband interference will be further reduced.

In the description of this application, unless otherwise stated, "/" means or, for example, A/B can mean A or B; "and/or" in this application is merely an association relationship describing associated objects , Indicates that there can be three kinds of relationships, for example, A and/or B, which can indicate: A alone exists, A and B exist at the same time, and B exists alone. In addition, in the description of this application, "a plurality of" means two or more.

Before describing the technical solutions of the embodiments of the present application, first, the technical scenarios of the embodiments of the present application will be described with reference to the drawings.

The technical solution of this application can be applied to various application communication systems, such as: vehicle to everything (V2X), vehicle LTE technology (LTE-vehicle, LTE-V), wireless data transmission between vehicles Technology (vehicle-to-vehicle communication, V2V), machine type communications (MTC), Internet of things (IoT), LTE-based machine type communication LTE-M, machine-to-machine communication (machine-to-machine communication) machine, MTM) and so on.

Figure 2 is a schematic diagram of network element connections in a multi-hop network, including: a base station (source node), user equipment (destination node), and at least one relay node on the link between the base station and the user equipment. Among them, the multi-hop network can be eLTE discrete spectrum aggregation (eLTE-DSA), mesh network, and other new air interface technologies (5th generation mobile networks, 5G NR) based on the fifth generation mobile communication system. Long term evolution (LTE), global system for mobile communication (GSM) and universal mobile telecommunications system (UMTS) are multi-hop networks established by air interface technologies.

Based on the aforementioned multi-hop network, the base stations in this application may include, for example, evolved base stations (eNB) and 5G base stations (gNB). Further, the base station of the present application may be a fixed base station, or a mobile base station installed on various transportation equipment, a ground base station, or a high-altitude base station installed on artificial earth satellites and high-altitude aircraft.

The user equipment (UE) in this application may include, for example, routing equipment, access point equipment (access point, AP), mobile phones, tablet computers, portable laptops, virtual\hybrid\augmented reality devices, and navigation devices. For electronic devices with wireless transceiver functions, user equipment can provide users with network communication services through wireless network connections with relay devices and base stations.

The relay node in this application refers to other node devices on the link of the multi-hop network except for the source node and the destination node, including routing devices with wireless relay capabilities and access point AP devices. For example, when the multi-hop network is an eLTE-DSA or 5G NR network, the relay node may be an integrated access and backhaul (IAB) node. In a multi-hop network, a relay node can be connected to child nodes including other relay nodes and user equipment to provide access to the child nodes. At the same time, the relay node can also be connected to other parent nodes or base stations to provide Information return function.

This application provides a frequency hopping method for a multi-hop network.

Fig. 3 is a flowchart of a frequency hopping method for a multi-hop network provided by this application. As shown in Figure 3, the method includes the following steps:

Step S101: The first device obtains a first message from a base station, where the first message is used to indicate a frequency hopping resource to the first device. The frequency hopping resource includes a set of frequency hopping carriers configured by the base station and a set of available frequency hopping carriers of the current sub-cell.

Among them, the first device may be any relay node in a multi-hop network. For example, the first device may be a routing device and an access point AP device with wireless relay capabilities, and integrated access and backhaul. backhaul, IAB) node equipment, etc. For example, the first device may implement corresponding functions through software, hardware, or a combination of software and hardware. It is easy to understand that, in order to achieve these functions, the first device may include a memory for storing a program corresponding to the function, and for executing the program. The memory, and the transceiver (such as: network card, radio frequency antenna, etc.) for sending and receiving data with the base station and the second device.

The first message of the base station may be, for example, radio resource control (RRC) of the base station. Therefore, the base station may indicate the frequency hopping resource to the first device through the RRC signaling. When the first device is a child node of the base station, the indication of RRC signaling can be directly sent to the first device. When the first device is another relay node, the indication of RRC signaling can be sent through the relay node on the link. The data is relayed and sent to the first device.

Wherein, when the base station indicates frequency hopping resources, it can indicate the same set of frequency hopping carriers for each first device (that is, each relay node in the multi-hop network), or it can indicate frequency hopping carriers with different ranges for the first device Set, the frequency hopping carrier set indicated by the base station may include all the carrier frequencies that can be used for frequency hopping transmission allocated by the base station for the multi-hop network, and may also include some carrier frequencies that can be used for frequency hopping transmission. Therefore, on the one hand, the number of carrier frequencies included in the frequency hopping carrier set can be much greater than the number of available carrier frequencies for the subcells of the first device, so that the first device subcells can use more carrier frequencies for frequency hopping. Transmission, to obtain a larger frequency hopping range, and improve the ability of sub-cells to fight against narrowband interference; on the other hand, when narrowband interference only occurs at a relatively certain carrier frequency point, the carrier frequency point pair included in the carrier frequency point set can exist The carrier frequency of narrowband interference is avoided, thereby improving the ability of the sub-cell to fight against narrowband interference.

Further, after the base station indicates the frequency hopping carrier set for the first device, it also indicates the available frequency hopping carrier set of the current sub-cell of the first device. For the first device, the available frequency hopping carrier set indicated by the base station may include all carrier frequencies in the frequency hopping carrier set, or may include some carrier frequencies in the frequency hopping carrier set.

Step S102: The first device generates a frequency hopping pattern according to the frequency hopping carrier set and the available frequency hopping carrier set.

Among them, the first device may obtain the frequency hopping switch, frequency hopping period, and frequency hopping formula from the system information of the cell or sub-cell that it accesses, such as system information block (SIB), to determine the frequency hopping pattern Therefore, it is possible to determine whether to perform frequency hopping transmission according to the frequency hopping switch, and determine the carrier frequency used for transmission after each frequency hopping from the set of available frequency hopping carriers according to the frequency hopping formula, thereby generating a frequency hopping pattern . Since the available frequency hopping carrier set includes all or part of the carrier frequency points of the frequency hopping carrier set, the base station can obtain a larger and adjustable frequency hopping range for the subcell of the first device by configuring the range of the available frequency hopping carrier set , So as to enhance the sub-cell's anti-narrowband interference ability, and improve the sub-cell's frequency domain diversity gain.

Step S103: The first device sends a second message to the second device, the second message includes the frequency hopping resource, and the second message is used to indicate the frequency hopping pattern to the second device.

In this application, the second device includes a relay node or user equipment that is connected to a sub-cell of the first device. For example, the second device may be a routing device with wireless relay capability and an access point AP device, and access back Integrated access and backhaul (IAB) node devices, mobile phones, personal computers, tablet computers, smart home devices, and transportation tools with network connectivity (such as cars, airplanes, trains, etc.), machinery and equipment, aerospace Devices, and other devices that can be defined as "things" in the Internet of Things (IoT) field.

Since the second device accesses the sub-cell of the first device, it needs to use the same frequency hopping pattern as the first device for frequency hopping transmission. Therefore, in order for the second device to obtain the frequency hopping pattern of the sub-cell, the first device The second device sends the second message carrying the frequency hopping resource, so that the second device obtains information such as the set of frequency hopping carriers and the set of available frequency hopping carriers required to generate the frequency hopping pattern. For example, the second device may implement corresponding functions through software, hardware, or a combination of software and hardware. It is easy to understand that, in order to achieve these functions, the second device may include a memory for storing programs corresponding to the functions and for executing programs. , And a transceiver (for example: network card, radio frequency antenna, etc.) for sending and receiving data with the first device.

As an achievable implementation, the second message may be a sub-cell system message broadcast by the first device to the sub-cell, such as the system information block SIB of the sub-cell. The first device may carry the sub-cell’s information in the sub-cell system message. Frequency hopping resources, as well as frequency hopping configuration information such as frequency hopping switch, frequency hopping cycle, and frequency hopping formula, so that any relay node device or user equipment connected to the sub-cell can obtain the frequency hopping resource from the sub-cell system message And frequency hopping configuration information, and then generate a frequency hopping pattern according to the frequency hopping resource and frequency hopping configuration information.

Further, in a multi-hop network such as eLTE-DSA, the sub-cell system message of the relay node usually contains only one system information block SIB1. In order to broadcast the frequency hopping resource and frequency hopping configuration information of the sub-cell of the present application, the SIB2 can be scheduled through the scheduling information (SchedulingInfoList) carried by SIB1, and the frequency hopping resources and frequency hopping configuration information can be configured in SIB2 for transmission.

Thus, in the method provided by the embodiment of the present application, the first device obtains the frequency hopping resource indicated by the base station through the first message of the base station; then, the first device generates the frequency hopping carrier set and the available frequency hopping carrier set included in the frequency hopping resource Frequency hopping pattern; finally, the first device sends frequency hopping resources to the second device to instruct the second device to obtain the same frequency hopping pattern, so that the first device and the second device can use the same frequency hopping pattern for frequency hopping transmission . Since the frequency range and number of the frequency hopping carrier set and the available frequency hopping carrier set indicated by the base station for the first device may not be limited by the carrier resources of the sub-cell, compared with the current cell-level frequency hopping scheme, this The applied method can make the sub-cells of the first device use more carrier frequency points for frequency hopping, thereby obtaining a larger frequency hopping range, and improving the ability of the sub-cells to resist narrowband interference.

Fig. 4 is a method for the base station to indicate frequency hopping resources to the first device shown in this application.

As shown in FIG. 4, in one embodiment, the first message includes first indication information, and the first indication information instructs the first device to obtain the frequency hopping carrier set from the third message of the third device. The first message further includes third indication information, the third indication information includes carrier index information, and the first device determines an available frequency hopping carrier set from the frequency hopping carrier set according to the carrier index information.

Among them, the third device may be the parent node of the second device. According to the position of the second device in the multi-hop network, the third device may be a base station or a relay node. Therefore, the third message may be a cell system message of the base station. It can be the sub-cell system message of the relay node.

The first indication information may be RRC signaling of the base station, and the base station may configure an indication message of a specified subsection length (for example: 1 bit) in the first indication information to instruct the first device to send a third message from the third device. Get the set of frequency hopping carriers. The third indication information may be RRC signaling of the base station, and the carrier index information carried in the third indication information may be a logical channel identifier (LCI), for example, it may include at most n (n is the carrier in the frequency hopping carrier set) The number of frequency points) index value, each index value is mapped to a carrier frequency point in the frequency hopping carrier set. Therefore, the base station can indicate through the carrier index information to use all or part of the carrier frequency points in the frequency hopping carrier set as the available frequency hopping carrier set of the first device sub-cell.

For example, the frequency hopping carrier set contains n carrier frequency points, which are respectively expressed as:

f0,f1,f2,…,fn-1

Among them, n is the number of carrier frequency points; then, the logical carrier index corresponding to the frequency hopping carrier set can be:

I0,I1,I2,…,In-1

Among them, Ii (0≤i<n) can correspond to the i-th carrier frequency point in the frequency hopping carrier set.

Therefore, by configuring part or all of the index values in the logical carrier index, any subset set can be determined from the frequency hopping carrier set.

Further referring to Fig. 4, after the first device obtains the frequency hopping carrier set and the available frequency hopping carrier set, it further broadcasts the frequency hopping carrier set and the available frequency hopping carrier set to the second device (sub-node) through the sub-cell system message, thereby The second device obtains the frequency hopping carrier set and the available frequency hopping carrier set from the sub-cell system message, and generates a frequency hopping pattern, so that the frequency hopping pattern can be used for frequency hopping transmission with the first device.

Fig. 5 is another method for the base station to indicate the frequency hopping resource to the first device shown in this application.

As shown in FIG. 5, in one embodiment, the first message includes second indication information, and the second indication information includes a set of frequency hopping carriers. The first message further includes third indication information, the third indication information includes carrier index information, and the first device determines an available frequency hopping carrier set from the frequency hopping carrier set according to the carrier index information.

The second indication information may be RRC signaling of the base station, and the base station may configure the frequency hopping carrier set by directly indicating the carrier frequency point in the second indication information. The third indication information may be RRC signaling of the base station, and the carrier index information carried in the third indication information may be a logical channel identifier (LCI). In this way, the base station can indicate through the carrier index information to use all or part of the carrier frequency points in the frequency hopping carrier set as the available frequency hopping carrier set of the first device sub-cell.

The method shown in Figure 5 can be applied to scenarios where available carrier frequencies are scarce, narrowband interference is infrequent, or narrowband interference only occurs in relatively certain carrier frequencies, so that the limited carrier frequencies can be fully utilized during frequency hopping transmission. Reasonable evasion of narrowband interference is carried out, so as not to occupy more frequency bandwidth and signaling overhead, but also to improve the ability of sub-cells to resist narrowband interference.

Fig. 6 is another method for the base station to indicate frequency hopping resources to the first device shown in this application.

As shown in FIG. 6, in one embodiment, the first message includes second indication information, and the second indication information includes a set of frequency hopping carriers. The first message further includes fourth indication information, where the fourth indication information is used to instruct the first device to determine the frequency hopping carrier set as an available frequency hopping carrier set.

The second indication information may be RRC signaling of the base station. The base station may configure the frequency hopping carrier set by directly indicating the carrier frequency in the second indication information, and then instruct the first device to perform frequency hopping through the fourth indication information. The carrier set serves as the available frequency hopping carrier set of the current sub-cell.

Therefore, the base station does not need to configure carrier index information (for example, logical carrier index LCI) in the third indication information, nor does it require the third device to broadcast the available frequency hopping carrier set of the first device subcell in the subcell system message. Thus, the signaling overhead when the base station configures frequency hopping resources is reduced.

Fig. 7 is another method for the base station to indicate the frequency hopping resource to the first device shown in this application.

As shown in FIG. 7, in an embodiment, the first message includes third indication information, and the third indication information includes a set of available frequency hopping carriers. The first message further includes fourth indication information, where the fourth indication information is used to instruct the first device to determine the available frequency hopping carrier set as the frequency hopping carrier set.

The third indication information may be RRC signaling of the base station, and the base station may configure the available frequency hopping carrier set of the first device sub-cell by directly indicating the carrier frequency in the third indication information, and then pass the fourth indication information Instruct the first device to use the frequency hopping carrier set as the frequency hopping carrier set of the current sub-cell.

Therefore, the base station does not need to configure carrier index information (for example, logical carrier index LCI) in the third indication information, nor does it require the third device to broadcast the available frequency hopping carrier set of the first device sub-cell in the sub-cell system message. Therefore, the signaling overhead when the base station configures frequency hopping resources is reduced.

As an achievable implementation manner, in the method in which the base station indicates the frequency hopping resource to the first device shown in FIG. 6 and FIG. 7, the base station may indicate the frequency hopping of the first device through an explicit indication or an implicit indication. Carrier set or available carrier set. Specifically, in the explicit indication, the base station may configure an indication field of a specified subsection length (for example: 1 bit) in the fourth indication information, so that the first device determines the frequency hopping carrier set according to the explicit indication message Is the available frequency hopping carrier set of the current sub-cell, or the available frequency hopping carrier set of the current sub-cell is determined as the frequency hopping carrier set. In the implicit indication, the fourth indication information of the base station has no indication field. In this case, the base station actually performs the default configuration on the first device through implicit indication, so that the first device sets the frequency hopping carrier Determine as the set of available frequency hopping carriers of the current sub-cell, or determine the set of available frequency hopping carriers of the current sub-cell as the set of frequency hopping carriers, or make the historical configuration of the first device base station determine the set of hopping carriers or available frequency hopping Carrier collection.

FIG. 8 is an example diagram of a base station provided by this application for configuring frequency hopping resources, showing a base station in a multi-hop network and a relay node 1 as a first device. As shown in Figure 8, the base station instructs the relay node 1 to indicate a frequency hopping carrier set, which specifically includes an uplink frequency hopping carrier used for uplink frequency hopping transmission, and a downlink frequency hopping carrier used for downlink frequency hopping transmission Carrier. Then, by indicating the logical carrier index to the relay node 1, the set of available frequency hopping carriers for the relay node 1 sub-cell is configured to include all or part of the remaining carrier frequency points after the set of frequency hopping carriers available for the base station cell is removed from the set of frequency hopping carriers , Make the available frequency hopping carrier set of the base station cell and the available frequency hopping carrier set of the relay node 1 sub-cell disjoint, and ensure that the base station cell and the relay node 1 sub-cell will not cause channel conflict during frequency hopping transmission.

As shown in FIG. 8, as an example, the frequency hopping carrier set configured by the base station includes the following carrier frequencies:

{f0,f1,f2,f3,f4,f7,f8,f9,f10,f11,f12}

The available frequency hopping carrier set of the base station cell configured by the base station includes the following frequency points:

{f0,f1,f2,f3,f4,f7,f8}

Then, if the base station configures the available hopping carrier set of the relay node 1 sub-cell, the available hopping carrier set of the relay node 1 sub-cell may include carrier frequencies, for example:

{f9,f10,f11,f12}

It should be supplemented that, in the scenario shown in Figure 8, the parent node of relay node 1 is the base station, and the base station configures the available frequency hopping carrier set of the relay node 1 sub-cell, so that the available hops of the relay node sub-cell 1 are The frequency carrier set does not intersect with the available frequency hopping carrier set of the base station cell; then, it is easy to understand that when the parent node of the relay node 1 is another relay node (not shown in Figure 8), the base station is the relay node 1. The configured available frequency hopping carrier set should not intersect with the available frequency hopping carrier set of the parent node child cell, so as to ensure that the relay node 1 child cell and its parent node child cell will not cause channel conflicts during frequency hopping transmission.

FIG. 9 is another example diagram of the base station configuration of frequency hopping resources shown in this application. Specifically, FIG. 9 shows the base station, the relay node 1 and the relay node 2 in a multi-hop network. Among them, the base station configures a part of the carrier frequencies of all available carrier frequencies of the multi-hop network as the hopping carrier set of the base station cell; then, select all or all of the remaining carrier frequencies from the hopping carrier set of the base station cell. Part of the carrier frequency points are configured to relay node 1 and relay node 2, as the hopping carrier set of relay node 1 sub-cell and relay node 2 sub-cell, and the relay node 1 sub-cell and medium are configured through the logical carrier index. Following the set of available hopping carriers in the sub-cell of node 2, the set of available hopping carriers in the sub-cell of relay node 1 and the set of available hopping carriers in the sub-cell of relay node 2 do not intersect, avoiding relay node 1’s sub-cell and intermediate The subsequent node 2 subcell produces channel conflicts during frequency hopping transmission.

In addition, as an achievable implementation, the base station can also configure a different set of frequency hopping carriers for each relay node sub-cell in the multi-hop network, and use the logical carrier index to configure the availability of each relay node sub-cell. The frequency hopping carrier set makes the available frequency hopping carrier sets of two adjacent relay node sub-cells disjoint and avoids channel conflicts.

As further shown in Figure 9, as an example, the frequency hopping carrier set configured by the base station includes the following carrier frequencies:

{f0,f1,f2,f3,f4,f7,f8,f9,f10,f11,f12}

Then, when the base station indicates the frequency hopping resources, it can select all or part of the carrier frequencies from the remaining available carrier frequencies {f5, f6, f13, f14, f15, f16,...} of the multi-hop network as the relay node 1 The frequency hopping carrier set of the cell. For example, the base station configures the frequency hopping carrier set of the relay node 1 sub-cell as:

{f5,f6,f13,f14}

Further, the logical carrier index indicated by the base station for the relay node 1 may correspond to all or part of the carrier frequency points in {f5, f6, f13, f14}, so that all or part of the carriers in {f5, f6, f13, f14} The frequency point is configured as the available frequency hopping carrier resource of the sub-cell of the relay node 1. For example, the available frequency hopping carrier set of the relay node 1 is configured as {f5, f6} or {f5, f6, f13, f14}, etc.

As further shown in Figure 9, for other relay nodes in a multi-hop network, taking relay node 2 as an example, the base station can configure relay node 2 with the same set of frequency hopping carriers as relay node 1, and then use logical carriers The index configures the available hopping carrier set of the relay node 2 sub-cell so that the available hopping carrier set of the relay node 2 sub-cell and the available hopping carrier set of the relay node 1 sub-cell do not intersect.

For example, the set of frequency hopping carriers configured by the base station for relay node 1 and relay node 2 is:

{f5,f6,f13,f14}

Then, if the base station configures the available frequency hopping carrier set of the relay node 1 subcell as {f5, f6}, it can configure the available frequency hopping carrier set of the relay node 2 subcell as {f13, f14}.

In addition, the base station can configure different frequency hopping carrier sets for each relay node. For example, the base station can also configure the frequency hopping carrier set of relay node 2 as: {f5, f6, f13, f14, f15, f16}, and Configure the available frequency hopping carrier set of the relay node 2 as {f15, f16} or {f13, f14, f15, f16}, etc. Therefore, during frequency hopping transmission, the frequency hopping resources of each sub-cell can be reasonably allocated according to the narrow-band interference faced by the sub-cells, avoiding the frequency points with narrow-band interference, making full use of the limited carrier frequency points, and improving sub-cell resistance. Narrowband interference capability.

FIG. 10 is another example diagram of the base station configuration of frequency hopping resources shown in this application. Specifically, FIG. 10 shows the base station, the relay node 1 and the relay node 2 in a multi-hop network. Among them, the base station configures part of the carrier frequency points of all available carrier frequencies of the multi-hop network as the frequency hopping carrier set of the base station cell, and then selects the remaining carrier frequency points from the frequency hopping carrier set of the base station cell. A part of the carrier frequency points are allocated to the relay node 1 and the relay node 2 as the frequency hopping carrier set and the available frequency hopping carrier set of the relay node 1 subcell and the relay node 2 subcell.

As further shown in FIG. 10, as an example, the frequency hopping carrier set configured by the base station includes the following carrier frequencies:

{f0,f1,f2,f3,f4,f7,f8}

Then, when the base station indicates frequency hopping resources, it can select a part of the carrier frequencies from the remaining available carrier frequencies {f5, f6, f9, f10, f11, f12, f13, f14, f15, f16,...} in the multi-hop network. The point serves as the set of frequency hopping carriers and the set of available frequency hopping carriers of the relay node 1 subcell and the relay node 2 subcell.

For example, the base station can configure the hopping carrier set and available hopping carrier set of the relay node 1 sub-cell as: {f5, f6, f9, f10}, configure the hopping carrier set and available hopping carrier set of the relay node 2 sub-cell The carrier set is: {f11, f12, f13, f14}.

In some embodiments, the base station or relay node indicating the set of frequency hopping carriers and the set of available frequency hopping carriers of its cell/subcell can be implemented in the following ways:

In the first achievable manner, the base station or relay node can configure the logical carrier index by directly indicating the index value, as an example:

Carrier frequency points include: {f0, f1, f2, f3, f4, f5, f6, f7, f8, f9, f10, f11, f12}

The corresponding index value is: {0,1,2,3,4,7,8,9,10,11,12}

Then, if the base station wants to configure {f0, f5, f6, f10, f11} as the available frequency hopping carrier set of the first device, then the logical carrier index indicated by the base station to the first device may include the following index values: {0,5 ,6,10,10}.

In the second achievable manner, the base station or relay node can configure the logical carrier index in a differential manner, for example:

Then, if the base station wants to configure {f0, f5, f7, f10} as the available frequency hopping carrier set of the first device, the logical carrier index indicated by the base station to the first device can be {1,5,2,3}, where , The first node f0 in the carrier frequency point set can be determined by "1", 5 represents the fifth node f5 after f0, 2 represents the second node f7 after f5, and 3 represents the third node after f7 f10. Therefore, the first device can determine the set of available frequency hopping carriers according to the logical carrier index using the above-mentioned differential method.

In the third achievable way, the base station or relay node can use the bitmap to indicate the set of frequency hopping carriers or the set of available frequency hopping carriers, where the frequency map can be defined by two values of 0 and 1. The selected state of each carrier frequency point, for example:

Then, if the base station wants to configure {f0, f5, f7, f10, f11, f12} as the frequency hopping carrier set of the first device, the frequency map that the base station can configure is: {1,0,0,0,0, 1,0,1,0,0,1,1,1}, therefore, the first device can determine the available carrier set according to the frequency map.

In an embodiment, the frequency hopping carrier set of the sub-cell of the first device may include non-hopping frequency points in the multi-hop network, and these non-hopping carrier frequency points may be, for example, primary synchronization signal (PSS). ), secondary synchronization signal (SSS), physical broadcast channel (physical broadcast channel, PBCH), system information block (system information block, SIB) and other common channel frequencies used. In order to avoid conflicts between the carrier frequency used for frequency hopping transmission of the sub-cell and the common channel frequency, the first device may generate a frequency hopping pattern that does not include the common channel frequency. In order to generate a frequency hopping pattern that does not include common channel frequency points, the first device first needs to know which carrier frequency points are common channel frequency points.

This application provides two implementation ways for the first device to acquire the frequency of the common channel:

In the first achievable manner, based on the method shown in FIG. 4, as shown in FIG. 11, the third message of the third device also includes frequency configuration information, and the frequency configuration information includes non-frequency hopping carrier frequency. . The third device may be the parent node of the second device. According to the position of the second device in the multi-hop network, the third device may be a base station or a relay node. Therefore, the third message may be a cell system message of the base station or a medium Follow the node’s sub-cell system message. The frequency point configuration information can be configured by the base station, and broadcast to the first device through the cell system message of the base station and the sub-cell system message of the relay node.

In the second achievable manner, based on the method shown in FIG. 4, as shown in FIG. 12, the first message further includes fifth indication information, the fifth indication information includes frequency point configuration information, and the fifth indication information may be In the RRC signaling of the base station, the frequency point configuration information includes the frequency point of the non-frequency hopping carrier.

Further, as shown in FIGS. 11 and 12, after the first device obtains the frequency point configuration information, it is further used to send the frequency point configuration information to the second device through a second message.

Based on the frequency point configuration information obtained by the first device through the above two methods, this application also provides two implementation ways for the first device to generate frequency hopping patterns that do not include non-frequency hopping carrier frequency points:

In the first achievable manner, the first device determines the hop number parity with the base station according to its own hop number in the multi-hop network; if the hop number parity is the same, the frequency hopping pattern generated by the first device is The downlink frequency hopping carrier set does not include non-frequency hopping carrier frequency points; if the hop number parity is different, the uplink frequency hopping carrier set of the frequency hopping pattern generated by the first device does not include the non-frequency hopping carrier frequency points.

The number of hops involved in this application is determined in the following way: In a multi-hop network, the base station at the top of the link can be regarded as the 0th hop node, and the child nodes of the base station can be shown as the 1st hop node, and the children of the 1st hop node The node can be regarded as the second hop node, and so on. Then, it is easy to understand that, based on the above definition of the number of hops, the hop number parity of the 0th hop node and the 2nd hop node are the same, and the hop number parity of the 0th hop node and the 1st hop node are different.

The first implementation of the first device of the present application to generate a frequency hopping pattern that does not include non-frequency hopping carrier frequencies can be used in a time division duplex (TDD) mode multi-hop network.

In TDD mode, because each node transmits uplink carrier and downlink carrier time-sharing, in a certain time sequence, if the base station is using the common channel frequency in the downlink carrier to transmit common channel messages such as PSS, SSS, PBCH, and SIB, then The odd-hop node (for example, the first hop node) is using the uplink carrier to receive the common channel message, and the even-hop node (for example, the second hop node) is using the downlink carrier to send the common channel message. In this sequence, if the uplink frequency hopping carrier set of the odd-hop node contains the common channel frequency, the common channel frequency may be used for uplink frequency hopping transmission, resulting in failure to receive the common channel message correctly. Similarly, if the first The downlink frequency hopping carrier set of even-hop nodes contains common channel frequency points, and the common channel frequency points may be used for downlink frequency hopping transmission, resulting in failure to send common channel messages correctly. Therefore, in order to ensure that the frequency used for frequency hopping transmission of each node does not conflict with the frequency of the common channel, and to enable each node to obtain the largest possible frequency hopping range, this application is based on the number of node hops and base station hopping. The parity between the numbers removes the common channel frequency points from the node's uplink frequency hopping carrier set or downlink frequency hopping carrier set, so that the corresponding frequency hopping pattern does not include the above common channel frequency points.

Illustratively, Fig. 13 is a schematic diagram of time-sharing transmission of multi-hop network nodes in TDD mode, showing the uplink frequency hopping carrier set, downlink frequency hopping carrier set and timing of the base station, the first hop node and the second hop node. With reference to Figure 13, in sequence 1, the base station uses two carrier nodes f3 and f5 in the downlink frequency hopping carrier set to transmit common channel messages. Therefore, these two carrier frequencies need to be removed from the downlink frequency hopping carrier set of the base station. At this time, the first hop node is an odd hop node, and f3 and f5 need to be removed from the uplink frequency hopping carrier set; the second hop node is an even hop node, and f3 and f5 need to be removed from the downlink frequency hopping carrier set; and so on . Thus, it is ensured that the carrier frequency used by each node for frequency hopping transmission does not conflict with the common channel frequency.

In the second achievable manner, the frequency point configuration information configured by the base station further includes frequency point removal indication information, and the uplink frequency hopping carrier set of the frequency hopping pattern generated by the first device according to the frequency point removal indication information does not include non- Frequency hopping carrier frequency; or, the downlink frequency hopping carrier set of the frequency hopping pattern generated by the first device according to the frequency removal indication information does not include the non-frequency hopping carrier frequency. Therefore, each node in the multi-hop network does not need to determine the number of hops in the multi-hop network, and it can also ensure that the carrier frequency used for frequency hopping transmission does not conflict with the common channel frequency.

In another embodiment, in order to avoid conflicts between the carrier frequency used for frequency hopping transmission and the frequency of the common channel, the first device may also determine the frequency point set used in the current frequency hopping period according to the frequency hopping pattern during frequency hopping transmission, and Determine whether the frequency point set contains common channel frequency points. If it includes common channel frequency points, the first device will delay the transmission behavior of the current frequency hopping cycle to the next frequency hopping cycle, or discard the transmission behavior of the current frequency hopping cycle, or download A frequency hopping cycle repeats the transmission behavior of the current frequency hopping cycle. Therefore, when the carrier frequency used for frequency hopping transmission and the common channel frequency are about to conflict, the transmission of the common channel frequency is prioritized to avoid conflicts.

This application also provides a frequency hopping method for a multi-hop network.

Fig. 14 is a flowchart of a frequency hopping method for a multi-hop network provided by this application. As shown in Figure 14, the method includes the following steps:

Step S201: The second device obtains a second message of the first device, the second message includes frequency hopping resources, and the frequency hopping resources include a set of frequency hopping carriers configured by the base station and a set of available frequency hopping carriers of the current sub-cell.

The first device may be any relay node in a multi-hop network, and the second device includes a relay node or user equipment that accesses a sub-cell of the first device. The second message may be the sub-cell system message of the first device, such as the system information block SIB of the sub-cell. The first device may carry the sub-cell frequency hopping resource, as well as the frequency hopping switch, frequency hopping period, and Frequency hopping formula and other frequency hopping configuration information, so that any relay node equipment or user equipment connected to the sub-cell can obtain the frequency hopping resource and frequency hopping configuration information from the sub-cell system message, and then according to the frequency hopping resource and hopping The frequency configuration information generates a frequency hopping pattern.

Step S202: The second device generates a frequency hopping pattern according to the frequency hopping carrier set and the available frequency hopping carrier set.

Wherein, the second device obtains the frequency hopping resources of the sub-cell from the sub-cell system message of the first device, as well as frequency hopping configuration information such as the frequency hopping switch, the frequency hopping period, and the frequency hopping formula, and determines whether to perform according to the frequency hopping switch. Frequency hopping transmission and frequency hopping formula determine the carrier frequency used for transmission after each frequency hopping from the set of available frequency hopping carriers, and then generate frequency hopping patterns. Since the available frequency hopping carrier set includes all or part of the carrier frequency points of the frequency hopping carrier set, the sub-cell of the first device can obtain a larger and adjustable frequency hopping range, thereby enhancing the sub-cell's ability to resist narrowband interference, and Improve the frequency domain diversity gain of the sub-cell.

Therefore, in the method provided by the embodiment of the present application, the second device obtains the second message of the first device, the second message contains the frequency hopping resource, and the frequency hopping resource includes the frequency hopping carrier set configured by the base station and the available subcells of the first device. Frequency hopping carrier set, so that the second device generates the frequency hopping pattern of the sub-cell of the first device according to the frequency hopping carrier set and the available frequency hopping carrier set, so as to realize frequency hopping transmission with the first device. Since the frequency range and number of the frequency hopping carrier set and the available frequency hopping carrier set indicated by the base station for the first device may not be limited by the carrier resources of the sub-cell, compared with the current cell-level frequency hopping scheme, this The applied method can enable the sub-cell of the first device to use more carrier frequency points for frequency hopping, thereby obtaining a larger frequency hopping range, and improving the ability of the sub-cell to resist narrowband interference.

In an embodiment, the frequency hopping carrier set of the sub-cell of the first device may include non-hopping frequency points in the multi-hop network, and these non-hopping carrier frequency points may be, for example, primary synchronization signal (PSS). ), secondary synchronization signal (SSS), physical broadcast channel (physical broadcast channel, PBCH), system information block (system information block, SIB) and other common channel frequencies used.

In order to avoid conflict between the carrier frequency used for frequency hopping transmission of the sub-cell and the frequency of the non-hopping carrier, the first device generates a frequency hopping pattern that does not include the frequency of the non-hopping carrier according to the frequency configuration information configured by the base station. Then, in order that the frequency hopping pattern generated by the second device does not include non-frequency hopping carrier frequencies, the first device needs to send frequency configuration information to the second device. Referring to FIG. 11 and FIG. 12, the first device may send frequency point configuration information to the second device through a second message, and the frequency point configuration information includes non-frequency hopping carrier frequency points.

Based on the frequency configuration information obtained by the second device from the first device, the second device uses the same method as the first device to generate a frequency hopping pattern that does not include non-frequency hopping carrier frequencies, including:

In the first achievable manner, the second device determines the hop number parity with the base station according to its own hop count in the multi-hop network; if the hop number parity is the same, the frequency hopping pattern generated by the second device is The downlink frequency hopping carrier set does not include non-frequency hopping carrier frequency points; if the hop number parity is different, the uplink frequency hopping carrier set of the frequency hopping pattern generated by the second device does not include the non-frequency hopping carrier frequency point. Therefore, it can be ensured that the frequency used for frequency hopping transmission of the second device does not conflict with the frequency of the non-frequency hopping carrier, and each node can obtain the largest possible frequency hopping range.

In the second achievable manner, the frequency point configuration information configured by the base station further includes frequency point removal indication information, and the frequency point removal indication information is used to indicate that the uplink frequency hopping carrier set of the frequency hopping pattern generated by the first device is not Including non-hopping carrier frequencies, or the generated downlink frequency hopping pattern does not include non-hopping carrier frequencies. The first device sends the frequency removal information to the second device through the second message, so that the second device generates the frequency hopping pattern according to the frequency removal indication information obtained from the second message and does not include non-non-frequency hopping carriers in the uplink frequency hopping carrier set. The frequency hopping carrier frequency, or, the downlink frequency hopping carrier set of the generated frequency hopping pattern does not include the non-frequency hopping carrier frequency. Therefore, the second device does not need to determine its own hop count in the multi-hop network, and can also ensure that the carrier frequency used for frequency hopping transmission does not conflict with the common channel frequency.

In another embodiment, in order to avoid conflicts between carrier frequencies used for frequency hopping transmission and non-frequency hopping carrier frequencies, the second device may also determine the set of frequency points used in the current frequency hopping period according to the frequency hopping pattern during frequency hopping transmission , And determine whether the frequency point set contains non-frequency hopping carrier frequency points. If it contains non-frequency hopping carrier frequency points, the second device delays the transmission behavior of the current frequency hopping cycle to the next frequency hopping cycle, or discards the current frequency hopping cycle Or repeat the transmission behavior of the current frequency hopping cycle in the next frequency hopping cycle. Therefore, when the carrier frequency used for frequency hopping transmission and the common channel frequency are about to conflict, the transmission of the common channel frequency is prioritized to avoid conflicts.

In the above-mentioned embodiments provided in this application, the schemes of the frequency hopping method of the multi-hop network provided in this application are introduced from the perspective of the device itself and the interaction between the devices. It can be understood that, in order to realize the above functions, each device, such as the first device and the second device, includes hardware structures and/or software modules corresponding to each function. Those skilled in the art should easily realize that in combination with the units and algorithm steps of the examples described in the embodiments disclosed herein, the present application can be implemented in the form of hardware or a combination of hardware and computer software. Whether a certain function is executed by hardware or computer software-driven hardware depends on the specific application and design constraint conditions of the technical solution. Professionals and technicians can use different methods for each specific application to implement the described functions, but such implementation should not be considered beyond the scope of this application.

For example, the above-mentioned devices implement corresponding functions through software modules.

In an embodiment, as shown in FIG. 15, the frequency hopping device of the multi-hop network includes a receiving module 301, a processing module 302, and a sending module 303, which can be used to perform the operations of the above-mentioned first device, for example:

The receiving module 301 is configured to obtain a first message of the base station, the first message is used to indicate frequency hopping resources to the frequency hopping device, and the frequency hopping resources include the frequency hopping carrier set configured by the base station and the available frequency hopping carrier set of the current sub-cell. The processing module 302 is configured to generate a frequency hopping pattern according to the frequency hopping carrier set and the available frequency hopping carrier set. The sending module 303 is configured to send a second message to the second device, the second message includes the frequency hopping resource, and the second message is used to indicate the frequency hopping pattern to the second device.

Optionally, the first message includes first indication information. The receiving module 301 is configured to obtain the frequency hopping carrier set from the third message of the third device according to the indication of the first indication information. The third device may be the parent node of the second device, and the third message may be the cell/sub-cell system message of the parent node. Therefore, the base station may configure the first device to obtain the hop from the cell/sub-cell system message of the parent node. Frequency carrier collection.

Optionally, the first message includes third indication information, and the third indication information includes carrier index information. The processing module 302 is configured to determine an available frequency hopping carrier set from the frequency hopping carrier set according to the carrier index information. Therefore, the base station can configure the available frequency hopping carrier set of the first device sub-cell through the carrier index information (for example, logical carrier index LCI), so that the frequency range and number of the available frequency hopping carrier set of the first device sub-cell are not affected by The carrier resource of the sub-cell is limited, thereby obtaining a larger frequency hopping range and improving the ability of the sub-cell to fight against narrowband interference.

Optionally, the first message includes fourth indication information. The processing module 302 is configured to determine the frequency hopping carrier set as an available frequency hopping carrier set according to the indication of the fourth indication information. Therefore, the base station instructs the first device to obtain the set of frequency hopping carriers and the set of available frequency hopping carriers with the same carrier frequency range, without configuring carrier index information (for example: logical carrier index LCI), thereby reducing the base station to configure the first device subcell Signaling overhead during frequency hopping resources.

Optionally, the third message includes frequency point configuration information, and the frequency point configuration information includes non-frequency hopping carrier frequency points.

Optionally, the processing module 302 is configured to determine the parity of the number of hops with the base station according to the number of hops of the frequency hopping device in the multi-hop network. The processing module 302 is further configured to not include non-frequency hopping carrier frequency points in the downlink frequency hopping carrier set of the frequency hopping pattern generated when the hopping parity is the same. The processing module 302 is further configured to not include non-frequency hopping carrier frequency points in the uplink frequency hopping carrier set of the frequency hopping pattern generated when the hop number and parity are different. Thus, it can be ensured that the carrier frequency used by the frequency hopping transmission of the first device does not conflict with the non-frequency hopping carrier frequency, and the largest possible frequency hopping range can be obtained.

Optionally, the frequency point configuration information further includes frequency point removal indication information. The processing module 302 is configured to not include non-frequency hopping carrier frequencies in the uplink frequency hopping carrier set of the frequency hopping pattern generated according to the frequency point removal indication information; or, the processing module 302 is configured to generate hops according to the frequency point removal indication information The downlink frequency hopping carrier set of the frequency pattern does not include non-frequency hopping carrier frequencies. Therefore, the first device does not need to determine the number of hops in the multi-hop network, and can also ensure that the carrier frequency used for frequency hopping transmission does not conflict with the non-frequency hopping carrier frequency.

Optionally, the processing module 302 is configured to determine a set of frequency points used in the current frequency hopping period according to the frequency hopping pattern. The processing module 302 is also used to determine whether a non-frequency hopping carrier frequency point is included in the frequency point set. The processing module 302 is also used to delay the transmission behavior of the current frequency hopping period to the next frequency hopping period when the frequency point set contains non-frequency hopping carrier frequency points, or discard the transmission behavior of the current frequency hopping period, or in the next hop cycle. The frequency cycle repeats the transmission behavior of the current frequency hopping cycle. Therefore, when the carrier frequency used for frequency hopping transmission conflicts with the non-frequency hopping carrier frequency, the transmission of the non-frequency hopping carrier frequency is given priority to avoid conflict.

In another embodiment, as shown in FIG. 16, the frequency hopping device of the multi-hop network includes a receiving module 301 and a processing module 302, which can be used to perform the operations of the above-mentioned second device, for example:

The receiving module 301 is configured to obtain a second message of the first device. The second message includes a frequency hopping resource. The frequency hopping resource includes a hopping carrier set configured by the base station and an available hopping carrier set of the current sub-cell. The processing module 302 is configured to generate a frequency hopping pattern according to the frequency hopping carrier set and the available frequency hopping carrier set.

Optionally, the processing module 302 is configured to determine the parity of the number of hops with the base station according to the number of hops of the frequency hopping device in the multi-hop network. The processing module 302 is further configured to not include non-frequency hopping carrier frequency points in the downlink frequency hopping carrier set of the frequency hopping pattern generated when the hopping parity is the same. The processing module 302 is further configured to not include non-frequency hopping carrier frequency points in the uplink frequency hopping carrier set of the frequency hopping pattern generated when the hop number and parity are different. Therefore, it can be ensured that the carrier frequency used by the frequency hopping transmission of the second device does not conflict with the non-frequency hopping carrier frequency, and the largest possible frequency hopping range can be obtained.

Optionally, the frequency point configuration information further includes frequency point removal indication information. The processing module 302 is configured to not include non-frequency hopping carrier frequencies in the uplink frequency hopping carrier set of the frequency hopping pattern generated according to the frequency point removal indication information; or, the processing module 302 is configured to generate hops according to the frequency point removal indication information The downlink frequency hopping carrier set of the frequency pattern does not include non-frequency hopping carrier frequencies. Therefore, the second device does not need to determine the number of hops in the multi-hop network, and can also ensure that the carrier frequency used for frequency hopping transmission does not conflict with the non-frequency hopping carrier frequency.
