Description

Technical Field

[0001] This disclosure relates to the field of communications, and more specifically, to a transmission method and apparatus, storage medium, and electronic device based on interference coordination. Background Technology

[0002] Integrated Access Backhaul (IAB) technology is one of the key technologies in 5G mobile communication systems and an important research direction. IAB technology allows 5G base stations to connect directly to the internet wirelessly, instead of via fiber optic connections, without requiring any additional equipment. That is, both the backhaul link between IAB nodes and the access link between user equipment and IAB nodes use wireless links for transmission. This significantly reduces backhaul and deployment costs for operators, helping them solve the problem of insufficient coverage. At the same time, IAB technology is also based on multi-hop technology using mobile relays. Utilizing multi-hops for service access and backhaul can greatly improve network deployment flexibility and reduce network construction costs.

[0003] In 5G communication networks, with the widespread adoption of smart terminals and the enrichment of mobile broadband services, network traffic is constantly increasing. To meet the rapid development of mobile data services, it is necessary to deploy many low-power IAB integrated small base stations as a key technology for achieving ultra-dense network deployment. How to efficiently allocate IAB node resources is a primary consideration for flexible IAB deployment and an effective method to improve spectrum utilization. In IAB technology, backhaul links and access links share wireless spectrum resources through time-division or frequency-division multiplexing, using the same wireless transmission technology, thereby reducing hardware and spectrum costs, lowering deployment costs, effectively ensuring the transmission quality of wireless backhaul links, and improving transmission reliability and effectiveness. However, wireless link transmission is a major factor affecting the performance of mobile communication networks. For 5G ultra-dense wireless access networks based on wireless self-backhaul technology, the transmission quality of both access and backhaul links directly affects the 5G user experience. Therefore, when allocating wireless resources, it is necessary to comprehensively consider user service needs, transmission link quality, and other factors, and to jointly consider access and backhaul links when allocating resources.

[0004] To address the aforementioned issues, this publication studies the interference management resource allocation problem based on the IAB system under 5G ultra-dense networking and proposes a transmission method based on interference coordination. Summary of the Invention

[0064] The following section will explain the above-mentioned transmission method based on interference coordination in conjunction with specific content.

[0065] In 5G ultra-dense network architectures, macro cells and micro cells collaborate in network deployment, where interference has become a key factor limiting user service quality and coverage. To address cross-link interference issues between users, macro base stations (MBS), and integrated access backhaul (IAB) nodes in 5G millimeter-wave high-order MIMO IAB network systems, including sidelobe interference suppression techniques and models for high-order multiple-in multiple-out (MIMO) technology and cross-link interference models, this application proposes a 5G-oriented wireless backhaul interference management and resource allocation scheme. Aiming to minimize the signal-to-interference-plus-noise ratio (SINR) of interfering links, and under optimal bandwidth resource allocation for backhaul and access links, beams are combined and matched according to limited beam directions. Through beam scanning, the optimal SINR beam pair is found, thereby minimizing the overall system interference while ensuring the communication quality of each link. This application also combines high-order MIMO beamforming technology with IAB technology. In terms of interference coordination, time division multiplexing (TDM) technology is used in the time slot configuration of macro base stations and small base stations to avoid interference between macro base stations and small base stations. Through high-order MIMO bidirectional beam training, design and selection, combined with time slot planning, beam domain scheduling and resource allocation, interference is managed and suppressed.

[0066] This application's embodiments achieve the determination of the physical layer beam model for high-order MIMO. Firstly, this application's embodiments focus on beam matching for millimeter-wave MIMO IAB systems. Based on the characteristics of the performance impact of different beam models, the performance bounds of millimeter-wave IAB systems are discussed. It is found that sidelobe interference has a significant impact on the system's maximum throughput, with lower sidelobe interference resulting in a more significant advantage for the IAB system. When using high-order MIMO in millimeter-wave IAB systems, beamforming sidelobe interference and cross-link interference are the most critical factors affecting the system's spectral efficiency. This application's embodiments propose a simplified bidirectional beam scanning scheme, effectively finding the optimal beam pair set in the beam space. In this embodiment, the transmitter beams are first trained to obtain the optimal transmitter set, and then the beams in the optimal transmitter set are sequentially matched with the receiver beams to obtain the optimal beam pairs for the transmitter and receiver. While meeting the system's information transmission requirements, the total system interference is minimized. This application's embodiments aim to minimize the total system interference while meeting the minimum system information transmission requirements, and design an optimal multi-beam pair selection algorithm. The algorithm first initializes relevant parameters based on the antenna panel orientation and finite beam direction, calculates the SINR (or transmission rate) of the IAB node's backhaul and access links, and then determines whether the SINR of each link meets the minimum channel requirements and can guarantee communication quality. With the goal of minimizing interference, it selects the optimal beam combination corresponding to the maximum SINR.

[0067] Figure 4 This is a system model diagram of an embodiment of this application. The system is a single-user MIMO IAB network system model, deploying a multi-antenna macro base station (MBS), a multi-antenna IAB node, and a single-antenna user (UE1). Both the MBS and IAB are configured with single-panel (8 4 2 1 1) antenna arrays. Using TDM technology, interference between the data transmission of the IAB backhaul link and the access link is avoided. The transmit power of the MBS is Pm = 46dBm, and the transmit power of the small base station is Ps = 33dBm. For TDM, assuming the total transmission time is T, and the time allocation factor between the backhaul link and the access link is η (0 ≤ η); then the backhaul link allocation time between the MBS and IAB is T1 = ηT, and the access link allocation time between the IAB and UE1 is T2 = (1-η)T. Here, Rb represents the backhaul link... For access links.

[0068] Figure 5This is a system flowchart of an embodiment of this application. The flowchart describes the process of solving the problem of minimizing system interference, performing beam selection, and obtaining the optimal beam combination. The process includes: setting the antenna panel direction and a limited number of beam directions; initializing relevant system parameters and calculating the SINR (or transmission rate) of the IAB node backhaul and access links; S506: calculating the beam gain for the target based on the target direction and beam direction, and selecting different beam combinations; S508: calculating the signal-to-noise ratio (SNR) of each link based on scene parameters and beam gain; S510: determining whether the SINR of each link meets the minimum channel requirement and can guarantee communication quality. If the conditions are met, proceed to S512; otherwise, abandon the beam combination and continue the loop in S506; S512: selecting an effective beam pair; S514: calculating and storing the SINR and system throughput of each link under the beam pair; S516: determining whether the system throughput has increased; if it has increased, then S518: updating the maximum system throughput and saving the corresponding beam pair information. S520: With the goal of minimizing interference, select the optimal beam combination corresponding to the maximum SINR to obtain the optimal beam combination. If the system throughput does not increase, then S512.

[0069] This application provides a wireless backhaul interference management and resource allocation scheme. The specific implementation steps are as follows:

[0070] Step 1: Obtain the specific location information and configuration parameter information of MBS, IAB nodes, and UE in the network. For example, taking the example above, obtain the specific location information and configuration parameter information of UE1.

[0071] Step 2: Calculate the transmission rates of the IAB node's backhaul link and access link.

[0072] Calculate the path gain between MBS, IAB, and UE1. The path loss model is as follows:

[0073] L(R)[dB]=A+20log 10 (f c )+10nlog 10 (R) (1)

[0074] Where f c The carrier frequency is in GHz, R represents the distance between the two communicating parties in meters (m), A is the attenuation value, and n is the path loss exponent.

[0075] Calculate the SINR of the IAB node backhaul link:

[0076]

[0077] SINR of the access link to the IAB node:

[0078]

[0079] Where hb represents the small-scale fading gain of the channel between MBS and IAB, hu represents the small-scale fading gain of the channel between IAB and UE1, Pm is the transmit power of MBS, Gx is the average gain of the antenna main lobe, PN is the noise power, d1 represents the distance between IAB and MBS, and d2 represents the distance between UE1 and IAB.

[0081]

[0082] Where B represents the communication bandwidth. Therefore, the throughput of the backhaul link and the access link can be obtained as follows:

[0083] C b =T1Blog2(1+SLNR) b (5)

[0084] and

[0086] Construct an optimization problem with the goal of minimizing the total system disturbance while satisfying the minimum requirements for Cb and Cu.

[0087]

[0088] Where st refers to satisfying a certain constraint condition.

[0089] Step 3: Set the antenna panel orientation and a limited beam direction. Based on the panel orientation and beam direction, calculate the beam gain to the target, select different beam combinations, and calculate the SINR of the IAB node's backhaul link and access link.

[0090] Step 4: Based on the SINR of the IAB node's backhaul link and access link, determine whether they meet the corresponding minimum requirements to ensure communication quality.

[0091] Step 5: With the goal of minimizing total system interference, select the optimal beam combination that meets the minimum SINR requirements of the IAB node's backhaul and access links, thus obtaining the optimal beam combination. The flowchart is as described above. Figure 5 .

[0092] The above is an example of an embodiment of this application and is not intended to limit this application.

[0093] This application's embodiments explore the interference problem experienced by the downlink IAB in multi-user MIMO multi-IAB scenarios, focusing on both one-hop and two-hop scenarios. It also investigates downlink interference coordination mechanisms in one-hop or multi-hop scenarios. Figure 6 This is a multi-user MIMO IAB system model according to this embodiment. The multi-user MIMO IAB system model is as follows: Figure 6 As shown. The multi-user IAB model is built on the basis of the single IAB model. 1 represents the link from MBS to IAB1, 2 represents the link from IAB1 to MBS, 3 represents the link from IAB1 to UE1, 4 represents the link from UE1 to IAB1, 5 represents the link from MBS to IAB2, 6 represents the link from IAB2 to MBS, 7 represents the link from IAB2 to UE2, and 8 represents the link from UE2 to IAB2.

[0094] The first step is to analyze the specific situation.

[0095] Case 1, such as Figure 7 As shown, in time slot T1, the MBS transmits signals to IAB1 and IAB2 respectively, mainly affecting links 1 and 5. Interference in IAB1 primarily originates from the MBS's transmission to IAB2, while interference in IAB2 originates from the MBS's transmission to IAB1. Figure 8 As shown, in time slot T2, IAB1 transmits a signal to UE1 and IAB2 transmits a signal to UE2. At this time, the main links are links 3 and 7. The interference of UE1 mainly comes from the signal transmitted from IAB2 to UE2, and the interference of UE2 comes from the signal transmitted from IAB1 to UE1.

[0096] Scenario 2, such as Figure 9 As shown, in time slot T1, MBS transmits signals to IAB1, and IAB2 transmits signals to UE2, mainly affecting links 1 and 7. Interference in IAB1 originates from the transmission of signals from IAB2 to UE2, while interference in UE2 originates from the transmission of signals from MBS to IAB1. Figure 10 As shown, in time slot T2, IAB1 transmits a signal to UE1, and MBS transmits a signal to IAB2. At this time, the main links are links 3 and 5. The interference of UE1 mainly comes from the signal transmitted by MBS to IAB2, and the interference of IAB2 comes from the signal transmitted by IAB1 to UE1.

[0097] In a multi-hop scenario of an IAB network, one example is as follows:

[0098] like Figure 11As shown, in time slot T1, MBS transmits signals to IAB1 and UE3, corresponding to links 1 and 3. The interference in IAB1 originates from the signal transmitted by MBS to UE3, and the interference in UE3 originates from the signal transmitted by MBS to IAB1. Figure 12 As shown, in time slot T2, IAB1 transmits signals to UE1 and IAB2, and MBS transmits signals to UE3, corresponding to links 3, 5, and 9. The interference to UE1 mainly comes from the signals transmitted by MBS to UE3 and from IAB1 to IAB2. The interference to IAB2 comes from the signals transmitted by IAB1 to UE1 and from MBS to UE3. The interference to UE3 mainly comes from the signals transmitted by IAB1 to both UE1 and IAB2. Figure 13 As shown, in time slot T3, IAB2 transmits a signal to UE2, and MBS transmits a signal to IAB1 and UE3. The corresponding links are links 1, 3, and 7. The interference in IAB1 mainly comes from the signal transmitted from MBS to UE3 and the signal transmitted from IAB2 to UE2. The interference in UE3 mainly comes from the signal transmitted from IAB2 to UE2 and the signal transmitted from MBS to IAB1. Since UE2 is far away from MBS, UE2 experiences less interference.

[0099] Step 2: Calculate the SINR (Signal Interference Rate) and interference for the corresponding link. Construct an optimization problem with the goal of minimizing the total system interference while satisfying the minimum transmission rate requirements of the relevant nodes.

[0100] Step 3: Set the antenna panel orientation and a limited beam direction. Based on the target direction and beam direction, calculate the gain of the multi-beam array on the target, select different beam combinations, and calculate the corresponding SINR.

[0101] Step 4: Based on the calculated SINR, determine whether it meets the corresponding minimum requirements to ensure communication quality.

[0102] Step 5: With the goal of minimizing the total system interference, select the optimal beam combination that meets the minimum SINR requirement of each link, and the optimal multi-beam pair combination is obtained.

[0103] The above is an example of an embodiment of this application and is not intended to limit this application.

[0104] As an example, the first node configures a measurement configuration for the second node. This measurement configuration includes a first measurement configuration and receives measurement results from the second node. The first measurement configuration refers to the second node performing link quality measurements within a corresponding configuration, indicating a link with minimal or no interference. The first node receives the measurement results fed back by the second node, indicating a link quality between the first node and the second node with minimal or no interference. The first node identifies the preferred link between the first and second nodes. In an IAB network, the first node is either the parent node or a CU node of the second node.

[0105] As an example, the first node configures a measurement configuration for the second node, including a second measurement configuration, and receives the measurement results from the second node. The second measurement configuration refers to the link quality measurement performed by the second node under a corresponding configuration, where the corresponding link experiences interference or significant interference. The first node receives the measurement results fed back by the second node, thus obtaining the link quality between the first and second nodes under interference conditions. The first node identifies the preferred link between the first and second nodes. In an IAB network, the first node is either the parent node or a CU node of the second node.

[0106] As an example, the first node configures a first reception pattern for the second node. This first reception pattern instructs the second node to perform reception on at least one of the following: time-domain resources, frequency-domain resources, and spatial-domain resources. For example, the first node uses a bitmap to indicate a time-domain pattern for the second node, where a bit of 0 represents state 1 and a bit of 1 represents state 2. State 1 indicates that the second node performs reception on the corresponding time resource, and state 2 indicates that the second node does not perform reception on the corresponding time resource; or, state 2 indicates that the second node performs reception on the corresponding time resource, and state 1 indicates that the second node does not perform reception on the corresponding time resource. The aforementioned time resource is one or a combination of OFDM symbols, time slots, subframes, and radio frames. For example, the first node uses a bitmap to indicate a frequency-domain pattern for the second node, where a bit of 0 represents state 1 and a bit of 1 represents state 2. State 1 indicates that the second node performs reception on the corresponding frequency-domain resource, and state 2 indicates that the second node does not perform reception on the corresponding frequency-domain resource; or, state 2 indicates that the second node performs reception on the corresponding frequency-domain resource, and state 1 indicates that the second node does not perform reception on the corresponding frequency-domain resource. The aforementioned frequency domain resources are one or a combination of subcarriers, resource blocks (RBs), bandwidth portions (BWPs), and carriers. For example, the first node uses a bitmap to indicate a spatial pattern for the second node, where a bit of 0 represents state 1 and a bit of 1 represents state 2. State 1 indicates that the second node performs reception on the corresponding spatial resource, and state 2 indicates that the second node does not perform reception on the corresponding spatial resource; or, state 2 indicates that the second node performs reception on the corresponding spatial resource, and state 1 indicates that the second node does not perform reception on the corresponding spatial resource. The aforementioned spatial resources are one or a combination of port indices, beam indices, pilot indices, and antenna panel indices. For another example, the first node uses multiple bitmaps to indicate two or more resource patterns in the time domain, frequency domain, and spatial domain respectively, or the first node uses a single multi-dimensional bitmap to uniformly indicate two or more resource patterns in the time domain, frequency domain, and spatial domain. In an IAB network, the first node is the parent node or CU node of the second node.

[0107] As an example, the second node acquires the measurement configuration of the first node. This measurement configuration includes a first measurement configuration. The second node performs the measurement and reports the measurement results. The first measurement configuration refers to the second node performing link quality measurements within the corresponding configuration, assuming the corresponding link is free of interference. No interference means that no other node besides the serving node is performing transmission operations on the same time and frequency domain resources. The second node feeds back the measurement results to the first node. The feedback quantity can be at least one of the following: Link Quality Index (CQI), Pilot Received Power (RSRP), Signal-to-Noise Ratio (SNR), or Received Signal Strength Indication (RSSI). The feedback granularity can be wideband or narrowband. In an IAB network, the second node is either a relay node or a UE (User Equipment). When the second node is a relay node, the link measurement performed by the second node refers to the relay node's Mobile Terminal Unit (MT) performing the link quality measurement. In NR, one type of relay node is the Integrated Access and Radio Backhaul (IAB) node.

[0108] As an example, the second node acquires the measurement configuration of the first node. This measurement configuration includes a second measurement configuration, the second node's measurements, and the reporting of the measurement results. The second measurement configuration refers to the second node performing link quality measurements within the corresponding configuration, assuming interference exists on the corresponding link. Interference exists because other nodes besides the serving node are performing transmission operations on the same time and frequency domain resources. The second node feeds back the measurement results to the first node, allowing the first node to obtain the link quality between the first and second nodes under conditions of interference or significant interference. The feedback quantity can be Link Quality Index (CQI) or Signal-to-Interference-plus-Noise Ratio (SINR). The feedback granularity can be broadband or narrowband. In an IAB network, the second node is either a relay node or a UE (User Equipment). When the second node is a relay node, the link measurement performed by the second node refers to the relay node's mobile terminal unit (MT) performing the link quality measurement. In NR, one type of relay node is the Integrated Access and Radio Backhaul (IABnode).

[0109] As an example, the second node acquires a first reception pattern. The second node determines at least one of the time-domain resources, frequency-domain resources, and spatial-domain resources corresponding to the reception. For example, the second node acquires a bitmap indicating a time-domain pattern, where bits 0 represent state 1 and bits 1 represent state 2. State 1 indicates that the second node performs reception on the corresponding time resource, and state 2 indicates that the second node does not perform reception on the corresponding time resource; or, state 2 indicates that the second node performs reception on the corresponding time resource, and state 1 indicates that the second node does not perform reception on the corresponding time resource. The aforementioned time resources are one or a combination of OFDM symbols, time slots, subframes, and radio frames. The second node determines the time resource corresponding to performing reception or not performing reception. For example, the second node acquires a bitmap indicating a frequency-domain pattern, where bits 0 represent state 1 and bits 1 represent state 2. State 1 indicates that the second node performs reception on the corresponding frequency-domain resource, and state 2 indicates that the second node does not perform reception on the corresponding frequency-domain resource; or, state 2 indicates that the second node performs reception on the corresponding frequency-domain resource, and state 1 indicates that the second node does not perform reception on the corresponding frequency-domain resource. The aforementioned frequency domain resources are one or a combination of subcarriers, resource blocks (RBs), bandwidth portions (BWPs), and carriers. The second node determines whether to perform reception on the corresponding frequency domain resources or not. For example, the second node acquires a bitmap indicating a spatial pattern, where bits 0 represent state 1 and bits 1 represent state 2. State 1 indicates that the second node performs reception on the corresponding spatial domain resources, and state 2 indicates that the second node does not perform reception on the corresponding spatial domain resources; or, state 2 indicates that the second node performs reception on the corresponding spatial domain resources, and state 1 indicates that the second node does not perform reception on the corresponding spatial domain resources. The aforementioned spatial domain resources are one or a combination of port indices, beam indices, pilot indices, and antenna panel indices. The second node determines the spatial domain resources for which reception is performed or not.

[0110] For example, the second node may acquire multiple bitmaps indicating two or more resource patterns in the time domain, frequency domain, and spatial domain, or the second node may acquire a single multi-dimensional bitmap indicating two or more resource patterns in the time domain, frequency domain, and spatial domain. The second node determines to receive at least one of the corresponding time-frequency resources, frequency domain resources, and spatial domain resources. In an IAB network, the second node is either a relay node or a UE (User Equipment). When the second node is a relay node, performing link measurement refers to the relay node's mobile terminal unit (MT) performing link quality measurement. In NR (Radio Networking), one type of relay node is the Integrated Access and Radio Backhaul (IAB) node.
