[0002] Currently, with the continuous development of communication technology, network application scenarios and user needs are becoming increasingly diversified, and the underlying system network architecture is also becoming more complex. In order to adapt to the increasingly complex network structure and enable communication networks to meet the needs of large-scale dense networking and high-bandwidth, high-frequency communication, the Integrated Access and Backhaul (IAB) technology can be used to achieve flexible deployment of millimeter-wave bands in 5G New Radio (5G NR) without proportionally increasing the density of fiber optic communication networks. This technology features low cost, rapid deployment, and easy maintenance.

[0003] However, in the above methods, since the allocation of wireless resources involves various wireless resources such as antennas, power, and spatial beams, and the relevant parameters such as time slots, frequency bands, and code domains of different systems are also different, it is impossible to allocate the resources of wireless backhaul and access links in a balanced manner, which affects network performance and results in poor rationality of the existing wireless resource allocation. Summary of the Invention

[0031] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0032] In the description of this application, unless otherwise stated, " / " means "or". For example, A / B can mean A or B. "And / or" in this document is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, and B alone. Furthermore, "at least one" and "multiple" refer to two or more. The terms "first," "second," etc., do not limit the quantity or order of execution, and "first," "second," etc., do not necessarily imply differences.

[0033] Currently, in related technologies, millimeter-wave radio frequency bands are typically used and densely deployed in wireless access networks to increase capacity and solve network coverage issues in 5G New Radio (5G NR). However, due to the ultra-dense wireless network deployment, the backhaul problem between base stations, especially small cells, and the core network becomes more prominent, posing a significant challenge to traditional backhaul solutions that rely on fiber optic communication networks. To address these issues, integrated access backhaul (IAB) technology has emerged. This technology uses wireless backhaul and relay communication to achieve dense and flexible deployment of millimeter-wave 5G NR cells without proportionally increasing the density of fiber optic communication networks. It is a low-cost, quick-to-deploy, and easy-to-maintain backhaul solution.

[0034] IAB (Integrated Access Bypass) technology was included as a feasibility study item in Release 15 of the 3rd Generation Partnership Project (3GPP) protocol. Preliminary standards and specifications were developed in Release 16, and further refinement was achieved in Release 17 by expanding application scenarios. However, current research on IAB technology, especially full-duplex (FD) IAB, is still incomplete. Furthermore, in the 5G era, diverse application scenarios and user demands have led to more complex network architectures. Existing research on wireless self-backhaul small cell resource allocation includes admission control, handover control, power control, and joint resource scheduling technologies for wireless access and backhaul, involving time slots, frequency bands, code domains, and various wireless resources such as antennas, power, and spatial beams. This has resulted in a lack of a unified standard and rationality in the allocation of wireless resources within these technologies.

[0035] The wireless resource allocation method provided in this application embodiment can be applied to a wireless resource allocation system. Figure 1 A schematic diagram of one structure of this wireless resource allocation system is shown. Figure 1 As shown, the wireless resource allocation system 20 includes: a macro base station 21, an IAB device 22, a first terminal device 23, and a second terminal device 24.

[0036] The wireless resource allocation system 20 can be used in the Internet of Things. The wireless resource allocation system 20 may include hardware such as multiple central processing units (CPUs), multiple memories, and storage devices storing multiple operating systems.

[0037] The macro base station 21 is connected to the IAB device 22 and the first terminal device 23 respectively, and is used to provide communication services for the IAB device 22 and the first terminal device 23.

[0038] The IAB device is connected to the macro base station 21 and the second terminal device 24 respectively, and is used to provide communication services to the second terminal device 24.

[0039] The first terminal device 23 is a terminal device connected to the macro base station 21, and can directly realize communication services through the macro base station 21.

[0040] The second terminal device 24 is a terminal device connected to the IAB device 22, and can directly realize communication services through the IAB device 22.

[0041] Optional, such as Figure 1 As shown, there can be multiple first terminal devices 23.

[0042] In one possible implementation, there can be multiple IAB devices, and there can also be multiple second terminal devices 24.

[0043] Optionally, the number of IAB devices 22, the number of first terminal devices 23, and the number of second terminal devices 24 will differ under different deployment schemes, and the corresponding data transmission links will also differ.

[0044] The following description, in conjunction with the accompanying drawings, describes a wireless resource allocation method provided by an embodiment of this application.

[0045] like Figure 2 As shown, an embodiment of this application provides a wireless resource allocation method, including steps S201-S204:

[0046] S201. Obtain the first parameter corresponding to the target wireless access backhaul integrated IAB system.

[0047] The IAB system includes: a macro base station, IAB equipment, and multiple terminal devices. The first parameter includes at least one of the following: sidelobe gain, first distance, second distance, fading gain, transmit power of the macro base station, average gain of the main lobe of the macro base station antenna, noise power, path loss, preset time allocation factor, and preset power optimization factor. The first distance is used to indicate the distance between the macro base station and the terminal devices, and the second distance is used to indicate the distance between the IAB equipment and the terminal devices.

[0048] Optionally, the first parameter can be obtained from the macro base station's log file.

[0049] Optionally, the fading gain can be the small-scale fading gain corresponding to the channel.

[0050] Optionally, a preset time allocation factor is used to implement time allocation between backhaul links and access links, and a preset power optimization factor is used to implement power allocation for each transmission link.

[0051] S202. Based on the first parameter, determine the signal-to-noise ratio (SNR) of each link among the multiple links included in the target IAB system.

[0052] These multiple links include: the link between the macro base station and the IAB device, the link between the macro base station and the terminal device, and the link between the IAB device and the terminal device.

[0053] Optionally, the specific links included in the IAB system under different deployment schemes can be determined based on information such as the relevant parameter files of the IAB system.

[0054] Optionally, the signal-to-noise ratio (SNR) is used to indicate the ratio of the signal power (useful signal) to the noise power (interference signal) of a link.

[0055] It should be noted that the parameters required for the signal power and noise power corresponding to the SNR of the link can be determined according to specific usage requirements.

[0056] Optionally, a link can be understood as a communication channel (channel) deployed in the target IAB system to realize communication services, such as the access link between the terminal device and the macro base station, and the backhaul link between the macro base station and the IAB device.

[0057] S203. Based on the SNR of each link in the multiple links, determine the throughput corresponding to each link using the Shannon formula.

[0058] Optionally, as shown in Formula 1, the throughput of each link can be determined based on the communication bandwidth of the target IAB system and the SNR of each link:

[0059] Formula 1

[0060] in, For the throughput corresponding to link i, Let B be the time slot corresponding to link i, and let B be the communication bandwidth corresponding to the target IAB system. Let be the signal-to-noise ratio corresponding to link i.

[0061] For example, in a Time Division Duplex (TDD) mode IAB system, when the backhaul link between the MBS and the IAB device only transmits data in the T1 time slot, and the signal-to-noise ratio corresponding to the backhaul link between the MBS and the IAB device is... At that time, the throughput of the backhaul link between MBS and IAB devices .

[0062] S204. Based on the throughput of each link, determine the second parameter corresponding to the target IAB system, and allocate resources to multiple terminal devices based on the macro base station according to the second parameter.

[0063] The second parameter includes the target time allocation factor and the target power optimization factor.

[0064] Optionally, a time allocation factor can be used to allocate the proportion of each time slot within the transmission time, and a power optimization factor can be used to allocate resources for each link within a single time slot, thereby achieving the allocation of wireless resources for each link.

[0065] In this embodiment, firstly, a first parameter corresponding to the target IAB system is obtained, including sidelobe gain, first distance, second distance, fading gain, macro base station transmit power, macro base station antenna main lobe average gain, noise power, path loss, preset time allocation factor, and preset power optimization factor. Based on the first parameter, the signal-to-noise ratio (SNR) of each link in the target IAB system, including the link between the macro base station and IAB devices, the link between the macro base station and terminal devices, and the link between the IAB devices and terminal devices, is determined. Then, based on the SNR of each link, the throughput of each link is determined using the Shannon formula. Based on the throughput of each link, a second parameter corresponding to the target IAB system, including the target time allocation factor and the target power optimization factor, is determined. Finally, resources are allocated to multiple terminal devices based on the macro base station according to the second parameter. Using the above method, the signal-to-noise ratio (SNR) of each link in the target IAB system can be determined based on multiple first parameters corresponding to the target IAB system. The throughput of each link can then be determined based on the SNR of each link. Furthermore, the second parameters of the target IAB system can be determined based on the throughput of each link, thereby enabling the allocation of wireless resources. By maximizing the total capacity of the target IAB system, the second parameters for wireless resource allocation are determined, thus improving the rationality of wireless resource allocation.

[0066] In one design, the target IAB system operates in Time Division Duplex (TDD) mode, such as... Figure 3 As shown, in a wireless resource allocation method provided in this application embodiment, the above-mentioned S202 includes S301-S302:

[0067] S301. Based on the first parameter, determine the SNR corresponding to the link between the macro base station and the IAB device and the SNR corresponding to the link between the macro base station and the first type of terminal device in the first time slot.

[0068] Among them, the first type of terminal equipment is the terminal equipment that connects to the macro base station in the first time slot.

[0069] It should be noted that Time Division Duplexing (TDD) mode means that signal transmission and reception are separated in time and do not conflict with each other. For example, the signal is transmitted first (the first time slot is used for signal transmission) and then received (the second time slot is used for signal reception).

[0070] For example, an IAB device in TDD mode can connect to a macro base station in the first time slot and to a terminal device in the second time slot.

[0071] S302. Based on the first parameter, determine the SNR corresponding to the link between the macro base station and the second type of terminal equipment and the SNR corresponding to the link between the IAB equipment and the third type of terminal equipment in the second time slot.

[0072] Among them, the second type of terminal equipment is the terminal equipment that connects to the macro base station in the second time slot, and the third type of terminal equipment is the terminal equipment that connects to the IAB equipment in the second time slot. The first time slot and the second time slot are two adjacent time slots.

[0073] Optionally, the first and second time slots constitute a complete data transmission service.

[0074] It should be noted that when the macro base station corresponds to different beams and the number of terminal devices is different, the number of time slots may also be different, and the number of time slots depends on the deployment scheme of the target IAB system.

[0075] For example, a complete data transmission time may also include a third time slot, a fourth time slot, etc.

[0076] For example, such as Figure 4 As shown, the target IAB system in time-division duplex mode includes a mobile base station (MBS) (i.e., a macro base station), IAB equipment, a first terminal equipment, a second terminal equipment, and a third terminal equipment. Both the MBS and IAB are equipped with antenna arrays, and each terminal equipment is equipped with a single antenna. In each transmission time slot, the MBS uses dual beams for information transmission. Assuming the total transmission time is T, and the time allocation factor for the backhaul link and access link is η0 (0 ≤ η0 ≤ 1), that is, the first time slot T1 is η0T, and the second time slot T2 is (1-η0)T. In time slot T1, the two beams of the MBS serve the backhaul link and the access link of the third terminal equipment, respectively. In time slot T2, the two beams of the MBS serve the access links of the third terminal equipment and the first terminal equipment, respectively. Simultaneously, in time slot T2, data transmission also occurs between the IAB and the access link of the second terminal equipment.

[0077] For MBS, since two links are transmitting data simultaneously in the same time slot, there is also the issue of power allocation between the two links. In time slot T1, the power allocation factor between the access link between MBS and the third terminal device and the backhaul link between MBS and IAB can be set to ρ1. In time slot T2, the power allocation factor between the access link between MBS and the first terminal device and between MBS and the three terminal devices can be set to ρ2.

[0078] It should be noted that the same terminal device may belong to multiple types of terminal devices at the same time. For example, the aforementioned third terminal device is a first-type terminal device when it is connected to the macro base station (MBS) in the first time slot, and a third-type terminal device when it is still connected to the macro base station (MBS) in the second time slot.

[0079] Optionally, in the first time slot, the signal-to-noise ratio (SNRb) of the link between MBS and IAB can be obtained using the following formula:

[0080] Formula 2

[0081] Wherein, SNRb is the signal-to-noise ratio corresponding to the link between MBS and IAB device in the first time slot, ρ1 is the power allocation factor between the access link between MBS and the third terminal device in the T1 time slot and the backhaul link between MBS and IAB device, Pm is the transmit power of macro base station, hb is the channel small-scale fading gain corresponding to MBS, G is the average gain of antenna main lobe, L(Rb) is the path loss corresponding to the link between MBS and IAB device, Rb is the distance between MBS and IAB device, PN is the noise power, h3 is the channel small-scale fading gain corresponding to the third terminal device, and z is the sidelobe gain.

[0082] Optionally, as shown in Formula 3, the path loss can be determined based on the attenuation value, carrier frequency, path loss exponent, and the distance between the communicating parties:

[0083] Formula 3

[0084] Where L is the path loss, A is the attenuation value, fc is the carrier frequency (in GHz), n is the path loss exponent, and R is the distance between the two communicating parties in the link.

[0085] Optionally, the distance between the two communicating parties corresponding to the link can be understood as the distance between the communicating devices corresponding to the link. For example, for the path loss L(Rb) corresponding to the link between MBS and IAB, Rb can be the distance between MBS and IAB devices.

[0086] Optionally, in the first time slot, the signal-to-noise ratio (SNRa31) of the link between the MBS and the third terminal device can be obtained using the following formula:

[0087] Formula 4

[0088] Wherein, SNRa31 is the signal-to-noise ratio corresponding to the link between the first time slot MBS and the third terminal device, L( The path loss is the link loss between the MBS and the third terminal device. denoted as , where is the distance between MBS and the third terminal device, and hb is the channel small-scale fading gain corresponding to MBS.

[0089] Optionally, for L( ), can be determined using Formula 3 above.

[0090] Optionally, in the second time slot, the signal-to-noise ratio (SNRa12) of the link between the MBS and the first terminal device can be obtained using the following formula:

[0091] Formula 5

[0092] Wherein, SNRa12 is the signal-to-noise ratio corresponding to the link between the MBS and the first terminal device in the second time slot, ρ2 is the power allocation factor between the access link between the MBS and the first terminal device in the T2 time slot and the access link between the MBS and the third terminal device, h1 is the channel small-scale fading gain corresponding to the first terminal device, and L( ) represents the path loss corresponding to the link between MBS and the first terminal device. L is the distance between MBS and the first terminal device. The path loss is the link loss between the IAB device and the first terminal device. denoted as , where is the distance between the IAB device and the first terminal device, and hs is the channel small-scale fading gain corresponding to the IAB device.

[0093] Optionally, for L( ) and L ( ), can be determined using Formula 3 above.

[0094] Optionally, in the second time slot, the signal-to-noise ratio (SNRa32) of the link between the MBS and the third terminal device can be obtained using the following formula:

[0095] Formula Six

[0096] Wherein, SNRa32 is the signal-to-noise ratio corresponding to the link between the second time slot MBS and the third terminal device, L( The path loss is the link loss between the MBS and the third terminal device. L is the distance between MBS and the third terminal device. The path loss is the link loss between the IAB device and the third-party terminal device. This refers to the distance between the IAB device and the third terminal device.

[0097] Optionally, for L( ), can be determined using Formula 3 above.

[0098] Optionally, in the second time slot, the signal-to-noise ratio (SNRa22) of the link between the IAB device and the second terminal device can be obtained using the following formula:

[0099] Formula 7

[0100] Wherein, SNRa22 is the signal-to-noise ratio corresponding to the link between the IAB device and the second terminal device in the second time slot, L( The path loss is the link loss between the IAB device and the second terminal device. L is the distance between the IAB device and the second terminal device. The path loss is the link loss between the MBS and the second terminal device.

[0109] It should be noted that, compared to half-duplex, full-duplex can transmit and receive data simultaneously on the same frequency band, significantly improving the capacity of the IAB system, but it also brings the problem of signal self-interference.

[0110] For example, such as Figure 6 As shown, the target IAB system in full-duplex mode includes a Mobile Base Station (MBS) (macro base station), IAB equipment, a first terminal equipment, a second terminal equipment, and a third terminal equipment. Both the MBS and IAB are equipped with antenna arrays, and the terminal equipment is equipped with a single antenna. In each transmission time slot, the MBS uses dual beams for information transmission. Assuming the total transmission time is T, and the time allocation factor for the backhaul link and the access link is η0 (0≤η0≤1), that is, the first time slot T1 is η0T, and the second time slot T2 is (1-η0)T. In time slot T1, the two beams of the MBS serve the backhaul link and the access link of the third terminal equipment, respectively; in time slot T2, the two beams of the MBS serve the backhaul link and the access link of the first terminal equipment, respectively. At the same time, during the entire transmission time T, the IAB equipment simultaneously transmits data with the backhaul link of the MBS and the access link of the second terminal equipment.

[0111] For MBS, since two links are transmitting data simultaneously in the same time slot, there is also the issue of power allocation between the two links. In time slot T1, the power allocation factor between the access link between MBS and the third terminal device and the backhaul link between MBS and IAB is ρ1.

[0130] Wherein, SNRa12 is the signal-to-noise ratio corresponding to the link between the MBS in the second time slot and the first terminal device, L( The path loss is the link loss between the IAB device and the first terminal device.

[0136] In this embodiment, by classifying the terminal devices of the target IAB system in full-duplex FD mode, the terminal devices connected to the MBS and IAB devices in each time slot are determined, and then the signal-to-noise ratio corresponding to each link in the target IAB system is determined, so as to allocate the radio resources corresponding to each link according to the signal-to-noise ratio of each link.

[0137] In a design, such as Figure 7 As shown, the wireless resource allocation method provided in this application embodiment further includes S501, and the "determining the SNR corresponding to the link between the macro base station and the IAB device in the first time slot based on the first parameter" in S401 includes S502, and the "determining the SNR corresponding to the link between the macro base station and the IAB device in the second time slot based on the first parameter" in S402 includes S503.

[0138] S501. Determine the corresponding self-interference cancellation coefficient between the macro base station and the IAB equipment.

[0139] It should be noted that since full-duplex mode can introduce self-interference of the signal, a self-interference cancellation coefficient can be introduced to reduce the impact of self-interference.

[0140] Optionally, the self-interference cancellation coefficient can be determined based on the isolation between the receiver and transmitter of the IAB device and the self-interference cancellation capability of the IAB device.

[0141] S502. Based on the first parameter and the self-interference cancellation coefficient, determine the SNR corresponding to the link between the macro base station and the IAB device in the first time slot.

[0142] Optionally, when determining the SNR corresponding to the link between the macro base station and the IAB device in the first time slot based on the first parameter and the self-interference cancellation coefficient, the above formula eight can be replaced by the following formula fourteen:

[0143] Formula Fourteen

[0146] Optionally, when determining the SNR corresponding to the link between the macro base station and the IAB device in the second time slot based on the first parameter and the self-interference cancellation coefficient, the above formula eleven can be replaced by the following formula fifteen:

[0147] Formula Fifteen

[0148] In this embodiment, a self-interference cancellation coefficient is introduced to eliminate the self-interference problem that may occur in full-duplex mode, thereby improving the accuracy of the link signal-to-noise ratio and thus improving the rationality of wireless resource allocation.

[0149] In a design, such as Figure 8 As shown, in a wireless resource allocation method provided in this application embodiment, the "determining the second parameter corresponding to the target IAB system based on the throughput corresponding to each link" in S204 above includes S601-S603:

[0150] S601. Determine the throughput of the target IAB system based on the throughput of each link.

[0151] Optionally, the throughput optimization function for the target IAB system can be determined based on the throughput of each link.

[0152] Optionally, the throughput for each link can be understood as a functional relationship between the throughput for each link and the preset time slot allocation factor and preset power allocation factor for each link.

[0153] For example, for a target IAB system in Time Division Duplex (TDD) mode, the corresponding throughput optimization function can be shown in Equation Sixteen:

[0154] Formula Sixteen

[0155] in, This represents the maximum capacity of the target IAB system in Time Division Duplex (TDD) mode. This represents the throughput of the link between the first time slot MBS and the third terminal device. This refers to the throughput of the link between the second time slot MBS and the third terminal device. This represents the throughput corresponding to the link between the second time slot MBS and the first terminal device. This refers to the throughput of the link between the MBS and IAB devices. This refers to the throughput of the link between the second time slot IAB device and the second terminal device. refer to and The minimum value between.

[0156] For example, for a target IAB system in full-duplex FD mode, the corresponding throughput optimization function can be shown in Equation 17:

[0157] Formula 17

[0158] in, The maximum capacity of the target IAB system in full-duplex FD mode. This represents the throughput of the link between the first time slot MBS and the third terminal device. This refers to the throughput corresponding to the link between the second time slot MBS and the first terminal. This refers to the throughput of the link between the MBS and IAB devices. This refers to the throughput of the link between the IAB device and the second terminal device. refer to and The minimum value between.

[0159] Optionally, since the IAB device is simultaneously connected to both the MBS and the second terminal device throughout the entire transmission time in full-duplex mode, the throughput corresponding to the link between the IAB device and the MBS needs to consider the throughput corresponding to the link between the IAB device and the MBS in both the first and second time slots, as shown in Formula 18; the throughput corresponding to the link between the IAB device and the second terminal device also needs to consider the throughput corresponding to the link between the IAB device and the second terminal device in both the first and second time slots, as shown in Formula 19.

[0160] Formula 18

[0161] Formula 19

[0162] S602. Adjust the preset time allocation factor and preset power optimization factor to determine the maximum throughput corresponding to the target IAB system.

[0163] Optionally, when adjusting the preset time allocation factor and preset power optimization factor, it is necessary to ensure that... .

[0164] S603. When the throughput corresponding to the target IAB system is the maximum throughput, the value of the preset time allocation factor is determined as the target time allocation factor, and the value of the preset power optimization factor is determined as the target power optimization factor.

[0165] In one design, the IAB system architecture within the target area can be obtained first. This IAB system architecture includes multiple target IAB systems. Then, the transmission method of each target IAB system is determined, and the capacity of each target IAB system is calculated. Based on the capacity of the target IAB system, a second parameter is optimized to determine the optimal allocation strategy for the radio resources of the target IAB system.

[0166] For example, such as Figure 9 As shown, when a Multiple-Input Multiple-Output (MIMO) IAB system includes only IAB systems in Time Division Multiplexing (TDM) TDD mode and TDM FD mode, the data transmission scheme of the target IAB system under different transmission modes can be determined first, and then the capacity of the target IAB system can be calculated. By using an optimization function, the capacity of the target IAB system can be maximized, and the radio resource allocation strategy with maximized capacity can be obtained. This radio resource allocation strategy is then determined as the optimal radio resource allocation strategy.

[0167] It should be noted that due to the use of large-scale antenna arrays and high communication bandwidth (especially in the millimeter-wave band), 5G NR macro base stations possess abundant frequency and spatial resources. While serving users within the same cell, they can use the NR air interface to provide wireless backhaul access to small base stations within the macro base station's coverage area that lack priority backhaul connections. This allows small base stations to establish backhaul links with the core network through multi-hop routing via the macro base station. Using this method, only high-speed fiber optic connections need to be deployed at the macro base station in the 5G access network, significantly reducing the difficulty and cost of laying fiber optic networks.

[0168] The basic architecture of IAB technology in the embodiments of this application is as follows: Figure 10As shown, macro base station A serves as a relay node (rTRP), IAB donor node (DN), and anchor node, enabling user access and small cell backhaul link utilization in the time, frequency, or spatial (e.g., beam-based operation) domains. Small base stations B or C become IAB nodes (IAB devices). According to relevant protocols (such as 3GPP), IAB nodes can serve users (second terminal devices) or act as parent IAB nodes cascading child IAB nodes to create multi-hop backhaul routes.

[0169] It should be noted that, in the embodiments of this application, the optimal allocation strategy of radio resources in TDM TDD / FD modes of MIMO IAB system is obtained by using the classical continuous convex approximation. This strategy has theoretical guarantees.
