Technical Field

[0003] In summary, various aspects of this disclosure relate to wireless communication, and to techniques and apparatus for measuring and reporting distributed inter-cell (DU) cross-link interference (CLI). Background Technology

[0004] Wireless communication systems are widely deployed to provide a variety of telecommunications services such as telephone, video, data, messaging, and broadcasting. Typical wireless communication systems employ multiple access technologies that enable communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access technologies include Code Division Multiple Access (CDMA) systems, Time Division Multiple Access (TDMA) systems, Frequency Division Multiple Access (FDMA) systems, Orthogonal Frequency Division Multiple Access (OFDMA) systems, Single Carrier Frequency Division Multiple Access (SC-FDMA) systems, Time Division Synchronous Code Division Multiple Access (TD-SCDMA) systems, and Long Term Evolution (LTE). LTE / Improved LTE is an enhanced set of the Universal Mobile Telecommunications System (UMTS) mobile standard released by the 3rd Generation Partnership Project (3GPP).

[0005] A wireless network may include multiple base stations (BSs) capable of supporting communication for multiple user equipments (UEs). UEs can communicate with the BS via downlinks and uplinks. A "downlink" (or "forward link") refers to the communication link from the BS to the UE, while an "uplink" (or "backlink") refers to the communication link from the UE to the BS. As will be described in more detail herein, a BS may be referred to as a Node B, gNB, Access Point (AP), Radio Headend, Transmitter-Receiver Point (TRP), New Radio (NR) BS, 5G Node B, etc.

[0006] The above multiple access technologies have been adopted in various telecommunications standards to provide a common protocol that enables different user equipment to communicate at the city, country, region, and even global levels. NR (which can also be referred to as 5G) is an enhancement set of the LTE mobile standard released by 3GPP. NR is designed to better integrate with other open standards by improving spectrum efficiency, reducing costs, improving service, utilizing new spectrum, and using Orthogonal Frequency Division Multiplexing (OFDM) with Cyclic Prefix (CP) (CP-OFDM) on the downlink (DL) and CP-OFDM and / or SC-FDM (e.g., also known as Discrete Fourier Transform Spread Spectrum OFDM (DFT-s-OFDM)) on the uplink (UL), thereby better supporting mobile broadband internet access, as well as beamforming, multiple-input multiple-output (MIMO) antenna technologies, and carrier aggregation. As the demand for mobile broadband access continues to grow, further improvements to LTE, NR, and other radio access technologies remain useful. Summary of the Invention

[0040] The various aspects of this disclosure are described more fully below with reference to the accompanying drawings. However, this disclosure may be embodied in many different forms and should not be construed as limited to any particular structure or function presented throughout this disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of this disclosure to those skilled in the art. Based on the teachings herein, those skilled in the art will understand that the scope of this disclosure is intended to cover any aspect of this disclosure disclosed herein, whether implemented independently of or in combination with any other aspect of this disclosure. For example, an apparatus or method may be implemented using any number of the aspects set forth herein. Furthermore, the scope of this disclosure is intended to cover such apparatus or methods implemented using structures, functions, or structures and functions other than or different from the aspects of this disclosure set forth herein. It should be understood that any aspect of this disclosure disclosed herein may be embodied by one or more elements of the claims.

[0041] Several aspects of a telecommunications system will now be described with reference to various devices and techniques. These devices and techniques will be described in detail below by various boxes, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"), and illustrated in the accompanying drawings. These elements can be implemented using hardware, software, or a combination thereof. Whether such an element is implemented as hardware or software depends on the specific application and the design constraints imposed on the entire system.

[0042] It should be noted that while the terms commonly associated with 5G or NR radio access technology (RAT) may be used to describe the aspects, the aspects of this disclosure may be applied to other RATs, such as 3G RAT, 4G RAT, and / or RATs after 5G (e.g., 6G).

[0043] Figure 1This is a diagram illustrating an example of a wireless network 100 according to this disclosure. Wireless network 100 may be or may include elements of a 5G (NR) network, and / or an LTE network, etc. Wireless network 100 may include multiple base stations 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d) and other network entities. A base station (BS) is an entity that communicates with user equipment (UE) and may also be referred to as an NR BS, Node B, gNB, 5G Node B (NB), access point, Transmitter Receiver Point (TRP), etc. Each BS can provide communication coverage for a specific geographic area. In 3GPP, the term "cell" may refer to the coverage area of ​​a BS and / or the BS subsystem serving that coverage area, depending on the context in which the term is used.

[0044] A BS can provide communication coverage for macrocells, picocells, femtocells, and / or another type of cell. A macrocell can cover a relatively large geographic area (e.g., a radius of several kilometers) and can allow unrestricted access by UEs with service subscriptions. A picocell can cover a relatively small geographic area and can allow unrestricted access by UEs with service subscriptions. A femtocell can cover a relatively small geographic area (e.g., a residential area) and can allow restricted access by UEs associated with that femtocell (e.g., UEs in a Closed User Group (CSG)). A BS used for macrocells can be referred to as a macro BS. A BS used for picocells can be referred to as a pico BS. A BS used for femtocells can be referred to as a femtocell BS or a home BS. Figure 1 In the examples shown, BS 110a can be a macro BS for macro cell 102a, BS 110b can be a pico BS for pico cell 102b, and BS 110c can be a femto BS for femto cell 102c. A BS can support one or more (e.g., three) cells. The terms “eNB,” “base station,” “NR BS,” “gNB,” “TRP,” “AP,” “Node B,” “5G NB,” and “cell” are used interchangeably herein.

[0045] In some respects, the cell may not be stationary, and the geographical area of ​​the cell may move depending on the location of the mobile BS. In some respects, BSs may interconnect with each other and / or with one or more other BSs or network nodes (not shown) in the wireless network 100 via various types of backhaul interfaces (e.g., direct physical connections or virtual networks, similar interfaces using any suitable transport network).

[0046] The wireless network 100 may also include a relay station. A relay station is an entity that can receive data transmissions from an upstream station (e.g., a BS or a UE) and transmit the data transmissions to a downstream station (e.g., a UE or a BS). A relay station can also be a UE capable of relaying transmissions for other UEs. Figure 1 In the example shown, relay BS 110d can communicate with macro BS 110a and UE 120d to facilitate communication between BS 110a and UE 120d. A relay BS can also be referred to as a relay station, relay base station, relay, etc.

[0047] Wireless network 100 can be a heterogeneous network comprising different types of Base Stations (BSs) (e.g., macro BSs, pico BSs, femto BSs, relay BSs, etc.). These different types of BSs can have different transmit power levels, different coverage areas, and different effects on interference in wireless network 100. For example, macro BSs can have high transmit power levels (e.g., 5 to 40 watts), while pico BSs, femto BSs, and relay BSs can have lower transmit power levels (e.g., 0.1 to 2 watts).

[0048] Network controller 130 can be coupled to a group of base stations (BSs) and can provide coordination and control for these BSs. Network controller 130 can communicate with the BSs via backhaul. BSs can also communicate with each other directly or indirectly via wireless or wired backhaul.

[0049] UE 120 (e.g., 120a, 120b, 120c) may be distributed throughout the wireless network 100, and each UE may be stationary or mobile. UE may also be referred to as an access terminal, terminal, mobile station, user unit, station, etc. UE may be a cellular phone (e.g., a smartphone), personal digital assistant (PDA), wireless modem, wireless communication device, handheld device, laptop computer, cordless phone, wireless local loop (WLL) station, tablet device, camera, gaming device, netbook, smartbook, ultrabook, medical device or apparatus, biometric sensor / device, wearable device (smartwatch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet, etc.)), entertainment device (e.g., music or video device, or satellite radio unit, etc.), vehicle component or sensor, smart meter / sensor, industrial manufacturing equipment, GPS device, or any other suitable device configured to communicate via wireless or wired media.

[0050] Some UEs can be considered Machine-Type Communication (MTC) or Evolved or Enhanced Machine-Type Communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, instruments, monitors, and / or location tags, which can communicate with a base station, another device (e.g., a remote device), or some other entity. Wireless nodes can provide connectivity to or to a network (e.g., a wide area network such as the Internet or cellular networks) via wired or wireless communication links, for example. Some UEs can be considered Internet of Things (IoT) devices, and / or can be implemented as NB-IoT (Narrowband Internet of Things) devices. Some UEs can be considered Customer Premises Equipment (CPE). UE 120 can be included within a housing that houses the components of UE 120 (e.g., processor components and / or memory components). In some aspects, the processor components and memory components can be coupled together. For example, the processor components (e.g., one or more processors) and memory components (e.g., memory) can be operatively coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0051] Typically, any number of wireless networks can be deployed in a given geographical area. Each wireless network can support a specific RAT and can operate on one or more frequencies. A RAT can also be referred to as a radio technology, air interface, etc. A frequency can also be referred to as a carrier, frequency channel, etc. Each frequency can support a single RAT in a given geographical area to avoid interference between wireless networks using different RATs. In some cases, NR or 5G RAT networks can be deployed.

[0052] In some respects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more sidelink channels (e.g., without using base station 110 as an intermediary for communication with each other). For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols or vehicle-to-infrastructure (V2I) protocols), and / or mesh networks. In this case, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described herein as being performed by base station 110.

[0053] Devices of wireless network 100 may communicate using the electromagnetic spectrum, which may be subdivided into various categories, bands, channels, etc., based on frequency or wavelength. For example, devices of wireless network 100 may communicate using an operating band having a first frequency range (FR1) spanning from 410 MHz to 7.125 GHz, and / or may communicate using an operating band having a second frequency range (FR2) spanning from 24.25 GHz to 52.6 GHz. The frequencies between FR1 and FR2 are sometimes referred to as intermediate frequency (IF) bands. Although a portion of FR1 is greater than 6 GHz, FR1 is generally referred to as the “sub-6 GHz” band. Similarly, FR2 is generally referred to as the “millimeter wave” band, although it differs from the Extremely High Frequency (EHF) band (30 GHz–300 GHz) designated as “millimeter wave” by the International Telecommunication Union (ITU). Therefore, unless explicitly stated otherwise, the terms “sub-6 GHz”, etc., should be understood to broadly refer to frequencies less than 6 GHz, frequencies within FR1, and / or intermediate frequency (e.g., greater than 7.125 GHz) if used herein. Similarly, unless otherwise explicitly stated, the terms "millimeter wave," etc., when used herein, can broadly refer to frequencies within the EHF band, frequencies within FR2, and / or intermediate frequency band frequencies (e.g., less than 24.25 GHz). It is anticipated that the frequencies contained in FR1 and FR2 can be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0054] As pointed out above, Figure 1 This is provided as an example. Other examples may differ from the one provided. Figure 1 The example described.

[0055] Figure 2 This is a diagram illustrating an example 200 of communication between a base station 110 and a UE 120 in a wireless network 100 according to the present disclosure. The base station 110 may be equipped with T antennas 234a to 234t, and the UE 120 may be equipped with R antennas 252a to 252r, wherein typically, T ≥ 1 and R ≥ 1.

[0056] At base station 110, transmitting processor 220 can receive data for one or more UEs from data source 212, select one or more modulation and coding schemes (MCS) for each UE based at least in part on channel quality indicators (CQI) received from each UE, process (e.g., code and modulate) the data for each UE based at least in part on the MCS selected for each UE, and provide data symbols for all UEs. Transmitting processor 220 can also process system information (e.g., semi-static resource allocation information (SRPI)) and control information (e.g., CQI requests, permission, and / or upper-layer signaling), and provide overhead symbols and control symbols. Transmitting processor 220 can also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signal (PSS) or secondary synchronization signal (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 can perform spatial processing (e.g., precoding, if applicable) on data symbols, control symbols, overhead symbols, and / or reference symbols, and can provide T output symbol streams to T modulators (MODs) 232a to 232t. Each modulator 232 can (e.g., for OFDM) process its corresponding output symbol stream to obtain an output sample stream. Each modulator 232 can further process (e.g., convert to analog, amplify, filter, and up-convert) the output sample stream to obtain a downlink signal. The T downlink signals from modulators 232a to 232t can be transmitted via T antennas 234a to 234t respectively.

[0057] At UE 120, antennas 252a to 252r can receive downlink signals from base station 110 and / or other base stations, and can provide the received signals to demodulators (DEMODs) 254a to 254r respectively. Each demodulator 254 can adjust (e.g., filter, amplify, down-convert, and digitize) the received signal to obtain an input sample. Each demodulator 254 can further process the input sample (e.g., for OFDM) to obtain a received symbol. MIMO detector 256 can obtain the received symbols from all R demodulators 254a to 254r, perform MIMO detection on the received symbols (if applicable), and provide the detected symbols. Receive processor 258 can process (e.g., demodulate and decode) the detected symbols, provide decoded data for UE 120 to data sink 260, and provide decoded control information and system information to controller / processor 280. The term "controller / processor" can refer to one or more controllers, one or more processors, or a combination thereof. The channel processor can determine parameters such as the Received Reference Signal Power (RSRP), Received Signal Strength Indicator (RSSI), Received Reference Signal Quality (RSRQ), and CQI. In some aspects, one or more components of the UE 120 may be included in the housing 284.

[0058] Network controller 130 may include communication unit 294, controller / processor 290, and memory 292. Network controller 130 may include one or more devices, such as those in a core network. Network controller 130 may communicate with base station 110 via communication unit 294.

[0059] Antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include or be included within the following: one or more antenna panels, antenna groups, antenna element sets, and / or antenna arrays, etc. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include one or more antenna elements. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include coplanar antenna element sets and / or non-coplanar antenna element sets. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include antenna elements within a single housing and / or antenna elements within multiple housings. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include one or more antenna elements coupled to one or more transmitting and / or receiving components (e.g., one or more components of 2).

[0060] On the uplink, at UE 120, the transmit processor 264 can receive and process data from data source 262 and control information from controller / processor 280 (e.g., for reports including RSRP, RSSI, RSRQ, and / or CQI). The transmit processor 264 can also generate reference symbols for one or more reference signals. Symbols from the transmit processor 264 can be pre-coded (if applicable) by TX MIMO processor 266, further processed by modulators 254a to 254r (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to base station 110. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 254) of UE 120 can be included in the modem of UE 120. In some aspects, UE 120 includes a transceiver. The transceiver may include any combination of antenna 252, modulator and / or demodulator 254, MIMO detector 256, receiver processor 258, transmitter processor 264, and / or TX MIMO processor 266. The processor (e.g., controller / processor 280) and memory 282 may be used to perform aspects of any of the methods described herein (e.g., as referenced). Figure 8-19 (Described).

[0061] At base station 110, uplink signals from UE 120 and other UEs can be received by antenna 234, processed by demodulator 232, detected by MIMO detector 236 (if applicable), and further processed by receiver processor 238 to obtain decoded data and control information transmitted by UE 120. Receiver processor 238 can provide decoded data to data sink 239 and decoded control information to controller / processor 240. Base station 110 may include communication unit 244 and communicate with network controller 130 via communication unit 244.

[0073] Although Figure 2 The boxes in the diagram are shown as different components, but the functions described above with respect to these boxes can be implemented in a single hardware, software, or combined component, or in various combinations of components.

[0074] As pointed out above, Figure 2 This is provided as an example. Other examples may differ from the one provided. Figure 2 The example described.

[0075] Figure 3 An example logical architecture of a distributed RAN 300 according to various aspects of this disclosure is shown. A 5G access node 306 may include an access node controller (ANC) 302. The ANC may be a base station CU of the distributed RAN 300. The backhaul interface to the next-generation core network (NG-CN) 304 may terminate at the ANC. The backhaul interface to the adjacent next-generation access node (NG-AN) 310 may terminate at the ANC. The ANC may include one or more TRPs 308 (which may also be referred to as BS, NR BS, Node B, 5G NB, AP, gNB, or some other term). As mentioned above, "TRP" can be used interchangeably with "cell".

[0076] TRP 308 can be a base station DU. The TRP can be connected to one ANC (ANC 302) or more ANCs (not shown). For example, for RAN sharing, Radio as a Service (RaaS), and service-specific ANC deployments, the TRP can be connected to more than one ANC. The TRP can include one or more antenna ports. The TRP can be configured to provide services to the UE individually (e.g., dynamically selected) or jointly (e.g., jointly transmitted).

[0077] The local architecture of RAN 300 can be used to illustrate fronthaul communication. This architecture can be defined to support fronthaul solutions across different deployment types. For example, the architecture can be at least in part based on the sending network capabilities (e.g., bandwidth, latency, and / or jitter).

[0078] This architecture can share features and / or components with LTE. Depending on various aspects, the NG-AN 310 can support dual connectivity with NR. The NG-AN310 can share common fronthaul for both LTE and NR.

[0079] This architecture enables collaboration between and within TRPs 308. For example, collaboration can be pre-configured within and / or across TRPs via ANC 302. Depending on the circumstances, inter-TRP interfaces may be unnecessary or nonexistent.

[0080] Depending on various factors, the dynamic configuration of the split logical functions can exist within the RAN 300 architecture. Packet Data Convergence Protocol (PDCP), Radio Link Control (RLC), or Media Access Control (MAC) protocols can be adaptively placed at the ANC or TRP.

[0081] Depending on the aspects, a base station may include a CU (e.g., ANC 302) and / or one or more DUs (e.g., one or more TRP 308).

[0082] As pointed out above, Figure 3 This is provided as an example. Other examples may differ from the one provided. Figure 3 The example described.

[0083] Figure 4 An example physical architecture of a distributed RAN 400 according to various aspects of this disclosure is shown. A centralized core network unit (C-CU) 402 can host core network functions. The C-CU can be deployed centrally. To handle peak capacity, C-CU functions can be offloaded (e.g., to Advanced Wireless Services (AWS)).

[0084] A centralized RAN Unit (C-RU) 404 (which may also be referred to as a base station CU) can host one or more ANC functions. Optionally, the C-RU can host core network functions locally. The C-RU can be deployed in a distributed manner. The C-RU can be located closer to the network edge.

[0085] Base station DU 406 can host one or more TRPs. Base station DU 406 can be located at the edge of a network with radio frequency (RF) capabilities.

[0086] As pointed out above, Figure 4 This is provided as an example. Other examples may differ from the one provided. Figure 4 The example described.

[0087] Figure 5 This is a schematic diagram illustrating example 500 of a radio access network according to this disclosure.

[0088] As shown by reference numeral 505 in the attached figure, a conventional (e.g., 5G, 4G, LTE, etc.) radio access network may include multiple base stations 510 (e.g., access nodes (ANs)), wherein each base station 510 communicates with the core network via a wired backhaul link 515 (such as a fiber optic connection). Base station 510 may communicate with UE 520 via an access link 525 (which may be a radio link). In some aspects, Figure 5 The base station 510 shown in the figure can be Figure 1 Base station 110 is shown in the image. In some aspects, Figure 5 The UE 520 shown in the figure can be Figure 1 The UE 120 shown in the image.

[0089] As indicated by reference numeral 550 in the attached figure, the radio access network may include a radio backhaul network, sometimes referred to as an IAB network. In an IAB network, at least one base station is an anchor base station 535 that communicates with the core network via a wired backhaul link 540 (such as a fiber optic connection). The anchor base station 535 may also be referred to as an IAB donor (or IAB-donor). The IAB network may include one or more non-anchor base stations 545, sometimes referred to as relay base stations or IAB nodes (or IAB-nodes). Non-anchor base stations 545 may communicate directly or indirectly with the anchor base station 535 via one or more backhaul links 550 (e.g., directly with the anchor base station 535 or via one or more non-anchor base stations 545) to form a backhaul path to the core network to carry backhaul services. The backhaul link 550 may be a radio link. The anchor base station 535 and / or the non-anchor base station 545 may communicate with one or more UEs 555 via an access link 560, which may be a radio link used to carry access services. In some aspects, Figure 5 The anchor base station 535 and / or non-anchor base station 545 shown in the diagram can be Figure 1 Base station 110 is shown in the image. In some aspects, Figure 5 The UE 555 shown in the figure can be Figure 1 The UE 120 shown in the image.

[0090] As indicated by reference numeral 565 in the accompanying drawings, in some aspects, radio access networks including IAB networks can use millimeter-wave technology and / or directional communication (e.g., beamforming, etc.) for communication between base stations and / or UEs (e.g., between two base stations, between two UEs, and / or between a base station and a UE). For example, a radio backhaul link 570 between base stations can use millimeter-wave signals to carry information and / or can use beamforming, etc., to be directed toward a target base station. Similarly, a radio access link 575 between a UE and a base station can use millimeter-wave signals and / or can be directed toward a target radio node (e.g., the UE and / or the base station). In this way, inter-link interference can be reduced.

[0091] Figure 5 The configuration of the base station and UE in the example is shown, and other examples are expected. For example, Figure 5 The one or more base stations shown can be replaced by one or more UEs communicating via a UE-to-UE access network (e.g., peer-to-peer network, device-to-device network, etc.). In this case, the anchor node can refer to a UE that communicates directly with a base station (e.g., an anchor base station or a non-anchor base station).

[0092] As pointed out above, Figure 5 This is provided as an example. Other examples may differ from the one provided. Figure 5 The example described.

[0093] Figure 6 This is a schematic diagram illustrating an example 600 of an IAB network architecture according to this disclosure.

[0094] like Figure 6 As shown, the IAB network may include an IAB donor 605 (shown as an IAB-donor) connected to the core network via a wired connection (shown as a wired backhaul). For example, the Ng interface of the IAB donor 605 may terminate at the core network. Additionally or alternatively, the IAB donor 605 may connect to one or more devices of the core network providing core access and mobility management functions (e.g., AMF). In some aspects, the IAB donor 605 may include a base station 110, such as an anchor base station, as described above. Figure 5As described, as shown in the figure, IAB donor 605 may include a CU, which can perform ANC functions, AMF functions, etc. The CU can configure the DU of IAB donor 605 and / or can configure one or more IAB nodes 610 (e.g., the MT and / or DU of IAB node 610) connected to the core network via IAB donor 605. Therefore, the CU of IAB donor 605 can control and / or configure the entire IAB network connected to the core network via IAB donor 605, for example, by using control messages and / or configuration messages (e.g., Radio Resource Control (RRC) configuration messages, F1 Application Protocol (F1AP) messages, etc.).

[0095] like Figure 6 As further illustrated, the IAB network may include IAB nodes 610 (shown as IAB-Node 1, IAB-Node 2, and IAB-Node 3) connected to the core network via IAB donor 605. As shown, IAB node 610 may include MT functionality (sometimes referred to as UE functionality (UEF)) and may include DU functionality (sometimes referred to as Access Node Function (ANF)). The MT functionality of IAB node 610 (e.g., a child node) may be controlled and / or scheduled by another IAB node 610 (e.g., the parent node of the child node) and / or by IAB donor 605. The DU functionality of IAB node 610 (e.g., the parent node) may control and / or schedule other IAB nodes 610 (e.g., the child nodes of the parent node) and / or UE 120. Therefore, DU may be referred to as a scheduling node or scheduling component, and MT may be referred to as a scheduled node or scheduled component. In some aspects, IAB donor 605 may include DU functionality but not MT functionality. That is, the IAB donor 605 can configure, control, and / or schedule the communication of the IAB node 610 and / or the UE 120. The UE 120 may include only the MT function and not the DU function. That is, the communication of the UE 120 can be controlled and / or scheduled by the IAB donor 605 and / or the IAB node 610 (e.g., the parent node of the UE 120).

[0096] When the first node controls and / or schedules communication for the second node (e.g., when the first node provides DU functionality for the second node's MT function), the first node can be referred to as the parent node of the second node, and the second node can be referred to as the child node of the first node. The child node of the second node can be referred to as the grandchild node of the first node. Therefore, the parent node's DU functionality can control and / or schedule communication for the parent node's child nodes. The parent node can be IAB donor 605 or IAB node 610, and the child node can be IAB node 610 or UE 120. Communication for the child node's MT function can be controlled and / or scheduled by the child node's parent node.

[0097] like Figure 6 As further illustrated, the link between UE 120 (e.g., which only has MT functionality and not DU functionality) and IAB donor 605, or between UE 120 and IAB node 610, can be referred to as access link 615. Access link 615 can be a radio access link that provides radio access to the core network to UE 120 via IAB donor 605 and optionally via one or more IAB nodes 610. Therefore, Figure 6 The network shown can be referred to as a multi-hop network or a wireless multi-hop network.

[0098] like Figure 6 As further illustrated, the link between IAB donor 605 and IAB node 610, or between two IAB nodes 610, can be referred to as backhaul link 620. Backhaul link 620 can be a wireless backhaul link that provides radio access to the core network to IAB node 610 via IAB donor 605 and optionally via one or more other IAB nodes 610. In the IAB network, network resources used for wireless communication (e.g., time resources, frequency resources, spatial resources, etc.) can be shared between access link 615 and backhaul link 620. In some aspects, backhaul link 620 can be a primary backhaul link or a secondary backhaul link (e.g., a backup backhaul link). In some aspects, if primary backhaul link 620 fails, becomes congested, becomes overloaded, etc., secondary backhaul link 625 can be used. For example, if the primary backhaul link between IAB node 2 and IAB node 1 fails, secondary backhaul link 625 between IAB node 2 and IAB node 3 can be used for backhaul communication. As used herein, a node or wireless node may refer to IAB donor 605 or IAB node 610.

[0099] As pointed out above, Figure 6 This is provided as an example. Other examples may differ from the one provided. Figure 6 The example described.

[0100] Figure 7 This is a schematic diagram illustrating an example 700 related to DU CLI according to the present disclosure.

[0101] In dynamic TDD, the allocation of network resources for uplink and downlink can be dynamically modified based on traffic load. For example, when a base station DU has uplink data to transmit, a base station CU can configure a TDD configuration (e.g., TDD mode) with more uplink transmission time intervals (TTIs) (e.g., frames, subframes, time slots, mini-time slots, symbols, etc.) for the base station DU, and when a base station DU has downlink data to receive, a TDD configuration with more downlink TTIs can be configured for the base station DU. The TDD configuration can be dynamically configured to modify the allocation of uplink and downlink TTIs for communication between the base station DU and its associated IAB child nodes, UE 120, IAB parent nodes, and / or base station CU.

[0102] like Figure 7 As shown, when adjacent base stations DU 705 communicate with upstream node 710 and / or downstream node 715 using different TDD configurations, this may cause the reception at base station DU 705-1 to overlap at least partially with the transmission at adjacent base station DU 705-2 in the time domain (e.g., occurring within the same TTI). These communications within the same TTI can interfere with each other, which may be referred to as inter-DU CLI 720.

[0103] As an example, inter-DU CLI 720 can occur at base station DU 705-1, where the reception of downlink communication 725 from upstream node 710-1 (e.g., an IAB parent node, a base station CU, or a DU of another type of upstream node) at base station DU 705-1 at least partially overlaps in the time domain with the transmission at base station DU 705-2. The transmission can be uplink communication 735 to upstream node 710-2 (which can be the same node as upstream node 710-1 or a different node, such as another IAB parent node, another base station CU, or a DU of another type of upstream node) and / or downlink communication 740 to downstream node 715-2 (e.g., an IAB child node, a UE, or a DU of another type of downstream node).

[0104] As another example, inter-DU CLI 720 can occur at base station DU 705-1, wherein uplink communication 745 received at base station DU 705-1 from downstream node 715-1 (e.g., IAB sub-node, UE, or DU of another type of upstream node) at base station DU 705-1 at least partially overlaps in the time domain with transmissions at base station DU 705-2 (e.g., transmissions of uplink communication 735 and / or downlink communication 740).

[0105] The inter-DU CLI 720, which receives downlink communication 725 and / or uplink communication 745, may cause reception problems for these communications, such as reduced receive power for downlink communication 725 and / or uplink communication 745, difficulties in demodulating downlink communication 725 and / or uplink communication 745, decoding errors in downlink communication 725 and / or uplink communication 745, and / or other problems. These and other reception problems may cause communication interruption or unreceivability at base station DU 705-1, which may result in reception delay, reduced reliability, and / or increased retransmissions (which consume additional power, memory, processing, and radio resources of base station DU 705-1 and the node performing retransmissions).

[0106] As pointed out above, Figure 7 This is provided as an example. Other examples may differ from the one provided. Figure 7 The example described.

[0107] The aspects described herein provide techniques and apparatus for inter-DU CLI measurement and reporting. A first base station DU (which may be a standalone base station DU or an IAB node DU) is capable of performing CLI measurements against one or more cells of a second base station DU (which may be a standalone base station DU or an IAB node DU) to detect, measure, report, and / or mitigate inter-DU CLI caused by the second base station DU. In some aspects, the first base station DU is capable of identifying resources (e.g., time-domain resources, frequency-domain resources) for performing CLI measurements against the second base station DU, at least in part, based on information associated with the second base station DU. The information associated with the second base station DU may include information implicitly indicating one or more resources (e.g., TDD configuration for the second base station DU), information explicitly indicating one or more resources (e.g., system information associated with the second base station DU, CLI measurement objects associated with the second base station DU, and / or other explicit indications) or a combination thereof.

[0108] In this manner, the first base station DU can identify one or more resources and perform one or more CLI measurements on one or more cells of the second base station DU. This enables the first base station DU to report information associated with the one or more CLI measurements to the associated base station CU in an attempt to mitigate the effects of inter-DU CLI between the first and second base station DUs, and / or to perform other actions based at least in part on the one or more CLI measurements. Accordingly, the one or more CLI measurements enable the first base station DU and / or other nodes (e.g., the second base station DU, the associated base station CU) to reduce, mitigate, and / or avoid reception delays, reduced reliability, and / or increased retransmissions that may otherwise result from inter-DU CLI. This reduces the power, memory, processing, and radio resources of the first base station DU, the second base station DU, and / or other nodes.

[0109] Figure 8 This is a schematic diagram illustrating one or more examples 800 associated with DU-to-CLI measurements and reporting according to this disclosure. Figure 8 As shown, Example 800 includes communication between multiple wireless network nodes, such as multiple base stations DU 805 (e.g., base station DU805-1 and base station DU 805-2), base station CU 810, base station MT 815, and / or OAM component 820. In some aspects, the nodes may be included in a wireless network (e.g., wireless network 100).

[0110] Base station DU 805 can implement, can be implemented by, and / or can be associated with: base station 110, TRP 308, DU 406, DU of non-anchor base station 545, DU of IAB node 610, DU 705, upstream node 710, downstream node 715, and / or Figure 12 The device 1200. The base station CU 810 can realize, can be realized by, and / or can be associated with: base station 110, ANC 302, C-RU 404, anchor base station 535, IAB donor 605, upstream node 710, and / or Figure 13 The device 1300. Base station MT 815 may implement, be implemented by, and / or be associated with: base station 110, non-anchor base station 545, and / or IAB node 610. OAM component 820 may implement, be implemented by, and / or be associated with network controller 130. OAM component 820 may be a component for managing and coordinating processes, tools, and standards involved in operating, managing, and maintaining a wireless network.

[0111] In some aspects, base stations DU 805 and CU 810 are non-IAB nodes. In other aspects, base stations DU 805, CU 810, and MT 815 are included in the IAB network (as described above). Figure 5 and / or Figure 6 In one or more IAB networks shown and described. In these examples, base station DU 805-1 and base station MT 815 may be associated with the same IAB node, base station DU 805-1 and base station DU 805-2 may be associated with different IAB nodes, and base station CU 810 may be associated with an IAB donor. In some aspects, base station DU 805-1 is associated with an IAB child node of an IAB parent node, which is associated with base station DU 805-2. In some aspects, base station DU 805-2 is associated with an IAB child node of an IAB parent node, which is associated with base station DU 805-1.

[0112] Base station DU 805-1 can be located near base station DU 805-2, such that transmissions of base station DU 805-2 in one or more cells of base station DU 805-2 can cause inter-DU CLIs with receptions of base station DU 805-1 in one or more cells of base station DU 805-1. Therefore, base station DU 805-1 can be configured to perform CLI measurements (e.g., inter-DU CLI measurements) of transmissions of base station DU 805-2. In some aspects, base station CU 810 configures base station DU 805-1 to perform CLI measurements. In some aspects, base station DU 805-1 performs CLI measurements autonomously.

[0113] As in Figure 8 As shown by reference numeral 825 in the accompanying drawings, base station DU 805-1 can receive information associated with base station DU 805-2 from one or more nodes (such as base station DU 805-2, base station CU 810, base station MT 815, and / or OAM component 820).

Base station DU 805-1 may identify one or more resources, at least in part, based on indications of one or more resources in the system information.

[0117] In some aspects, the information associated with base station DU 805-2 includes one or more CLI measurement objects of one or more cells associated with base station DU 805-2. In these examples, base station DU 805-1 may receive one or more CLI measurement objects from base station CU 810.

[0118] CLI measurement objects may include one or more parameters for performing one or more CLI measurements between DUs, one or more parameters from base station DU 805-2 for measuring CLI measurements to be performed against base station DU 805-2, and / or configuration of other parameters. One or more CLI measurement objects may identify one or more resources (e.g., one or more time-domain resources, and / or one or more frequency-domain resources), and may identify the measurement window in which base station DU 805-1 will perform CLI measurements of one or more cells of base station DU 805-2 (e.g., start time-domain resource, end time-domain resource, duration, period, and / or other parameters for the measurement window), the subcarrier spacing (SCS) of one or more cells of base station DU 805-2 in which base station DU 805-1 will perform CLI measurements, the reference signal configuration for one or more cells of base station DU 805-2, the cell identifier associated with each cell in one or more cells of base station DU 805-2 in which CLI measurements will be performed, and the index of the SSB transmitted from base station DU 805-2, and / or other parameters.

The type of reference signal can include SSB, Channel State Information Reference Signal (CSI-RS), Remote Interference Management Reference Signal (RIM-RS), Phase Tracking Reference Signal (PTRS), DMRS, and / or other types of reference signals. In some aspects, one or more CLI measurement objects can also identify one or more transmit beams that base station 805-2 will use for transmission in one or more resources. In these examples, the indication can be an explicit indication of one or more transmit beams, an implicit indication of one or more beams by indicating a quasi-co-location (QCL) reference to one or more SSB indices, or an indication of one or more transmit beams using another type of indication.

[0122] As noted above, in some aspects, base station DU 805-1 is a DU associated with an IAB node. Base station MT 815 can be an MT associated with an IAB node and can be co-located with base station DU 805-1. In these examples, base station DU 805-1 can receive information associated with base station DU 805-2 from base station MT 815. In some aspects, base station MT 815 receives information associated with base station DU 805-2 in an SSB Measurement Timing Configuration (SMTC) for base station DU 805-2 for use in Radio Resource Management (RRM) measurements for one or more cells of base station DU 805-2. In some aspects, base station MT 815 can acquire information associated with base station DU 805-2 by performing inter-node discovery to detect and / or measure one or more cells of base station DU 805-2. Therefore, base station MT 815 can provide information associated with base station DU 805-2 via a local connection with base station DU 805-1.

[0123] Additionally and / or alternatively, base station DU 805-2 may also be a DU associated with another IAB node. In these examples, the IAB node associated with base station DU 805-1 may be an IAB parent node or an IAB child node of the IAB node associated with base station DU 805-2. IAB nodes may exchange resource and / or configuration information as part of an IAB child-parent configuration, which may include information associated with base station DU 805-2 as well as other information, such as allocated DU cell resources (e.g., indicating hard, soft, unavailable and / or uplink, downlink, flexible resources), SSB resources and / or configuration, reference signals, control resource set (CORESET), and / or other types of information.

[0124] As in Figure 8Furthermore, as shown by reference numeral 835, base station DU 805-1 can perform one or more CLI measurements for a cell associated with base station DU 805-2, at least in part, based on one or more resources identified in the information associated with base station DU 805-2.

The one or more CLI measurements may include RSSI measurement, RSRP measurement, RSRQ measurement, CQI measurement, signal-to-noise ratio (SNR) measurement, signal-to-interference-plus-noise (SINR) measurement, and / or other types of signal measurements.

[0125] Base station DU 805-1 can perform one or more CLI measurements of one or more communications transmitted using one or more resources. The one or more communications may include CLI-RSSI transmissions (e.g., Physical Downlink Shared Channel (PDSCH) transmissions, Physical Downlink Control Channel (PDCCH) transmissions, Physical Uplink Shared Channel (PUSCH) transmissions, Physical Uplink Control Channel (PUCCH) transmissions), reference signal transmissions (e.g., SSB, CSI-RS, RIM-RS, PTRS, DMRS), and / or other types of transmissions. The one or more communications may be transmitted in one or more time-domain resources, one or more frequency-domain resources, on one or more transmit beams, and / or may be transmitted according to other parameters indicated in and / or by information associated with base station DU 805-2.

[0126] In some aspects, base station DU 805-1 may transmit the results of one or more CLI measurements and / or other information associated with one or more CLI measurements to base station DU 805-2, base station CU 810, OAM component 820, and / or other nodes. Additionally and / or alternatively, base station DU 805-1 may automatically perform one or more actions to reduce, mitigate, and / or eliminate inter-DU CLI between base station DU 805-1 and base station DU 805-2. For example, base station DU 805-1 may align its transmission schedule with the transmission schedule of cells associated with base station DU 805-1 that has performed one or more CLI measurements. As another example, base station DU 805-1 may align its reception schedule with the reception schedule of cells associated with base station DU 805-2 that has performed one or more CLI measurements. As another example, base station DU 805-1 can align its TDD configuration with the TDD configuration of the cell associated with base station DU 805-2 that has performed one or more CLI measurements, so that base station DU 805-1 and base station DU 805-2 transmit and / or receive at similar times.

[0127] As another example, base station DU 805-1 can adjust the transmit power of one or more cells and / or one or more UE 120s and / or one or more IAB sub-nodes of IAB nodes associated with base station DU 805-1. As another example, base station DU 805-1 can coordinate with base station DU 805-2 for airspace resources associated with cells associated with base station DU 805-2 that have performed one or more CLI measurements. As another example, base station DU 805-1 can schedule URLLC uplink communication or URLLC downlink communication during scheduled transmission resources (e.g., scheduled uplink transmission resources or scheduled downlink transmission resources) for cells associated with base station DU 805-2 that have performed one or more CLI measurements. As another example, base station DU 805-1 can schedule one or more types of uplink communication, such as random access channel (RACH), service request (SR), sounding reference signal (SRS), and / or PDCCH, during the scheduling of transmission resources for cells associated with base station DU 805-2 that has performed one or more CLI measurements.

[0129] Figure 9This is a schematic diagram illustrating one or more examples 900 associated with DU-to-CLI measurements and reporting according to this disclosure. (See also...) Figure 9 As shown, Example 900 includes communication between multiple wireless network nodes (e.g., multiple base stations DU 905 (e.g., base station DU 905-1 and base station DU 905-2) and multiple base stations CU 910 (e.g., base station CU 910-1 and base station CU 910-2)). In some aspects, the nodes may be included in a wireless network (e.g., wireless network 100).

[0130] Base station DU 905 can, can be implemented by, and / or can be associated with: base station 110, TRP 308, DU 406, DU of non-anchor base station 545, DU of IAB node 610, DU 705, upstream node 710, downstream node 715, and / or Figure 12 The device 1200.

In some aspects, base station CU 910-1 is associated with the IAB donor of the IAB node used for base station DU 905-1, and base station CU 910-1 is associated with a different IAB donor of the IAB node used for base station DU 905-2.

[0132] Base station DU 905-1 may be located near base station DU 905-2, such that a transmission of base station DU 905-2 in one or more cells of base station DU 905-2 may cause inter-DU CLI with a reception of base station DU 905-1 in one or more cells of base station DU 902-1. Therefore, base station DU 905-1 may be configured to perform CLI measurements (e.g., inter-DU CLI measurements) of transmissions of base station DU 905-2. In some aspects, base station CU 910-1 configures base station DU 905-1 to perform CLI measurements. In some aspects, base station DU 905-1 performs CLI measurements autonomously. In some aspects, base station CU 910-1 and / or base station CU 910-2 configure base station DU 905-2 to perform transmissions for which base station DU 905-2 performs CLI measurements.

[0133] As in Figure 9 As shown by reference numeral 915 in the accompanying drawings, base stations CU 910-1 and CU 910-2 can coordinate one or more resources for CLI measurements. For example, base stations CU 910-1 and CU 910-2 can coordinate time-domain and / or frequency-domain resources, in which base station DU 905-2 will perform transmissions for CLI measurements, and base station DU 905-1 will perform CLI measurements for the transmissions.

The resource configuration may include a transmission resource configuration, which may be an STC or similar type of transmission configuration. In some aspects, base station CU 910-1 sends information identifying one or more resources directly to base station DU 905-2. In some aspects, base station CU 910-1 sends information identifying one or more resources to base station DU 905-2 through one or more intermediate nodes (such as one or more other base station DUs, base station CU 910-2 (e.g., via the Xn interface), and / or other nodes).

[0136] As in Figure 9 As further shown by reference numeral 930 in the accompanying drawings, the base station DU 905-2 can perform one or more transmissions (e.g., CLI measurement transmissions) in one or more resources. The one or more transmissions may include the one or more reference signal types described above, the one or more CLI-RSSI transmission types described above, and / or other types of transmissions.

[0137] As in Figure 9 As further shown by reference numeral 935, base station DU 905-1 can perform one or more CLI measurements for one or more transmissions, at least in part, based on information received from base station CU910-1. The one or more CLI measurements may include one or more of the aforementioned measurement types, such as RSSI measurement, RSRP measurement, CQI measurement, SNR measurement, SINR measurement, and / or other types of signal measurements. Base station DU 905-1 may send the results of one or more CLI measurements (and, in some examples, other information associated with the one or more CLI measurements) to base station CU 910-1 in a CLI measurement report.

[0171] The aspects described herein provide techniques and apparatus for CLI measurements and reporting between DUs. A base station CU may be able to provide a CLI measurement report configuration to a first base station DU (which may be a DU of a non-IAB base station or a DU of an IAB node). The CLI measurement report configuration may indicate one or more parameters for performing one or more CLI measurements associated with a second base station DU (which may be a DU of a non-IAB base station or a DU of an IAB node), one or more parameters for configuring CLI measurement reports for the one or more CLI measurements, and / or one or more parameters for sending CLI measurement reports.

[0172] In this manner, the first base station DU is capable of performing one or more CLI measurements, configuring CLI measurement reports for one or more CLI measurements, and / or transmitting CLI measurement reports at least in part based on CLI measurement report configuration. The base station CU can receive CLI measurement reports and can be configured for communication between the first base station DU, the second base station DU, and / or one or more other base stations to reduce, mitigate, and / or avoid reception delays; to improve reliability; and / or to reduce the number of retransmissions that may otherwise result from inter-DU CLI. This saves power, memory, processing, and radio resources for the first base station DU, the second base station DU, and / or other nodes.

[0173] Figure 14 This is a diagram illustrating one or more examples 1400 of CLI measurements and reporting between DUs in accordance with this disclosure. Figure 14 As shown, Example 1400 includes communication between multiple wireless network nodes (e.g., multiple base stations DU 1405 (e.g., base station DU 1405-1 and base station DU 1405-2), base station CU 1410, and / or OAM component 1415). In some aspects, nodes may be included in a wireless network (e.g., wireless network 100).

[0174] Base station DU 1405 can implement, can be implemented by, and / or can be associated with: base station 110, TRP 3014, DU 406, DU of non-anchor base station 545, DU of IAB node 610, DU 705, upstream node 710, downstream node 715, and / or Figure 18 The device 1800. The base station CU 1410 can implement, can be implemented by, and / or can be associated with: base station 110, ANC 302, C-RU 404, anchor base station 535, IAB donor 605, upstream node 710, and / or Figure 19The device 1900. The OAM component 1415 may be implemented by, be implemented by, or be associated with the network controller 130. The OAM component 1415 may be a component for managing and coordinating the processes, tools, and standards involved in operating, managing, and maintaining a wireless network.

[0175] In some respects, base stations DU 1405 and CU 1410 are non-IAB nodes. In other respects, base stations DU 1405 and CU 1410 are included in the IAB network (e.g., in conjunction with the above). Figure 5 and / or Figure 6 In one or more IAB networks shown and described. In these examples, base station DU 1405-1 and base station MT may be associated with the same IAB node, base station DU 1405-1 and base station DU 1405-2 may be associated with different IAB nodes, and base station CU 1410 may be associated with an IAB donor. In some aspects, base station DU 1405-1 is associated with an IAB child node of an IAB parent node, which is associated with base station DU 1405-2. In some aspects, base station DU 1405-2 is associated with an IAB child node of an IAB parent node, which is associated with base station DU 1405-1.

[0176] Base station DU 1405-1 may be located near base station DU 1405-2, such that transmissions of base station DU 1405-2 in one or more cells of base station DU 1405-2 may cause inter-DU CLIs with receptions of base station DU 1405-1 in one or more cells of base station DU 1405-1. Therefore, base station DU 1405-1 may be configured to perform CLI measurements (e.g., inter-DU CLI measurements) of transmissions of base station DU 1405-2. In some aspects, base station CU 1410 configures base station DU 1405-1 to perform CLI measurements. In some aspects, base station DU 1405-1 autonomously performs CLI measurements.

[0177] As in Figure 14As shown by reference numeral 1420 in the accompanying drawings, base station CU 1410 can send CLI measurement report configuration to base station DU 1405-1, and base station DU 1405-1 can receive CLI measurement report configuration. Alternatively or additionally, base station DU 1405-1 can receive CLI measurement report configuration from base station DU 1405-2 or OAM component 1415. Alternatively or additionally, base station DU 1405-1 can be configured with CLI measurement report configuration without signaling from other nodes. In these examples, base station DU 1405-1 can be configured with CLI measurement report configuration before or during deployment in the wireless network.

[0178] CLI measurement report configuration can indicate one or more parameters for performing one or more CLI measurements (e.g., for inter-DU CLI), one or more parameters for configuring CLI measurement reports for one or more CLI measurements, one or more parameters for transmitting CLI measurement reports, and / or one or more other CLI measurement parameters. For example, CLI measurement report configuration can instruct base station DU 1405-1 to perform one or more CLI measurements for the base station DU and associated cell. As another example, CLI measurement report configuration can instruct base station DU 1405-1 to use the receive beam for performing one or more CLI measurements. As another example, CLI measurement report configuration can instruct base station DU 1405-2 to use the transmit beam for transmitting reference signals or other CLI measurement transmissions for one or more CLI measurements (e.g., by indicating the SSB index, CSI-RS index, or CLI-RSSI resource identifier).

[0179] As another example, the CLI measurement report configuration may indicate the resources (e.g., time-domain resources, frequency-domain resources) in which base station DU 1405-1 will perform one or more CLI measurements (e.g., which may be indicated by one or more CLI measurement objects). As another example, the CLI measurement report configuration may indicate the resources (e.g., time-domain resources, frequency-domain resources) in which base station DU 1405-1 will use to send CLI measurement reports. As another example, the CLI measurement report configuration may include CLI measurement filtering parameters that indicate how base station DU 1405-1 will filter CLI measurements.

[0180] In some aspects, the CLI measurement report configuration instructs base station DU 1405-1 to report CLI measurements and associated information for all base station DUs and associated cells for which base station DU 1405-1 performs CLI measurements. In some aspects, the CLI measurement report configuration instructs base station DU 1405-1 to report CLI measurements and associated information for the K strongest aggressor cells among the base station DUs and associated cells for which base station DU 1405-1 performs CLI measurements (e.g., this may be determined at least in part based on RSSI or another signal strength CLI measurement). In some aspects, the CLI measurement report configuration instructs base station DU 1405-1 to report CLI measurements and associated information for the M weakest aggressor cells among the base station DUs and associated cells for which base station DU 1405-1 performs CLI measurements (e.g., this may be determined at least in part based on RSSI or another signal strength CLI measurement).

[0181] In some aspects, the CLI measurement report configuration instructs base station DU 1405-1 to report CLI measurement and association information for a specific number of base station DUs and associated cells for which base station DU 1405-1 will perform CLI measurements (e.g., where base station DU 1405-1 selects base station DUs and associated cells). As another example, the CLI measurement report configuration may instruct base station DU 1405-1 to report CLI measurement and association information for base station DUs and associated cells for which the corresponding CLI measurements meet measurement thresholds (e.g., RSSI threshold, RSRP threshold, CQI threshold, SNR threshold, SINR threshold, and / or another signal measurement or interference threshold).

[0182] In some aspects, the CLI measurement report configuration instructs base station DU 1405-1 to report the results of one or more CLI measurements performed against the base station DU and associated cells indicated in the CLI measurement report configuration. In some aspects, the CLI measurement report configuration indicates the type of CLI measurement to be performed, such as RSSI measurement, RSRP measurement, CQI measurement, SNR measurement, SINR measurement, and / or other types of signal measurement. In some aspects, the CLI measurement report configuration instructs base station DU 1405-1 to report propagation delay and / or round-trip time (RTT) information associated with the base station DU and associated cells against which base station DU 1405-1 will perform CLI measurements.

[0183] In some aspects, the CLI measurement report configuration instructs base station DU 1405-1 to report the interference level category (e.g., inter-DU CLI level) for each base station DU and associated cell for which base station DU 1405-1 will perform CLI measurements. Each interference level category (e.g., low, medium, high) may correspond to a corresponding signal measurement range or interference range. The interference level category for a particular base station DU and associated cell may be determined at least in part based on one or more CLI measurements for the cell and base station DU. In some aspects, the CLI measurement report configuration instructs the reporting frequency at which base station DU 1405-1 will send CLI measurement reports. For example, the CLI measurement report configuration may instruct base station DU 1405-1 to send periodic or semi-persistent CLI measurement reports (e.g., at specific time intervals), event-triggered CLI measurement reports (e.g., at least in part based on the occurrence of a specific event), or dynamic CLI measurement reports (e.g., one-off or non-repetitive CLI measurement reports).

[0184] As in Figure 14 As shown by reference numeral 1425 in the accompanying drawings, base station DU 1405-1 can identify the CLI measurement report configuration. In some aspects, base station DU 1405-1 identifies the CLI measurement report configuration at least in part based on receiving the CLI measurement report configuration from base station CU 1410. In some aspects, base station DU 1405-1 identifies the CLI measurement report configuration at least in part based on having a CLI measurement report configuration configured (e.g., without additional signaling from base station CU 1410).

[0185] As in Figure 14 As shown by reference numeral 1430, base station DU 1405-1 can configure CLI measurement reports for one or more CLI measurements associated with base station DU 1405-2, at least in part, based on CLI measurement report configuration. In some aspects, base station DU 1405-1 can also perform one or more CLI measurements, at least in part, based on CLI measurement report configuration. In these examples, base station DU 1405-1 performs one or more CLI measurements for the cell of base station DU 1405-2 identified in the CLI measurement report configuration, performs one or more CLI measurement types in one or more resources identified in the CLI measurement report configuration, performs one or more CLI measurement types identified in the CLI measurement report configuration, performs one or more CLI measurements using a receive beam and / or at least in part based on a transmit beam indicated in the CLI measurement report, and / or filters one or more CLI measurements at least in part based on CLI measurement filtering parameters in the CLI measurement report configuration.

[0186] In some aspects, base station DU 1405-1 configures its CLI measurement report to include the results of one or more CLI measurements, at least in part based on CLI measurement report configuration. In some aspects, base station DU 1405-1 configures its CLI measurement report to include indications of one or more measurement types (e.g., RSSI measurement, RSRP measurement, CQI measurement, SNR measurement, SINR measurement, and / or one or more other types of measurement) for one or more CLI measurements, at least in part based on CLI measurement report configuration. In some aspects, base station DU 1405-1 may configure its CLI measurement report to include an identifier (and an identifier of the associated measurement resource) of each cell associated with base station DU 1405-2 that satisfies a measurement threshold (e.g., RSSI measurement threshold, RSRP measurement threshold, CQI measurement threshold, SNR measurement threshold, SINR measurement threshold, and / or another type of measurement threshold) for the corresponding CLI measurement.

[0187] In some aspects, base station DU 1405-1 configures its CLI measurement report, at least in part, to include indications of one or more receive beams used for one or more CLI measurements, based on CLI measurement report configuration. In some aspects, base station DU 1405-1 configures its CLI measurement report, at least in part, to include indications of one or more transmit beams associated with base station DU 1405-2 that were previously used for one or more transmissions associated with one or more CLI measurements. In some aspects, base station DU 1405-1 configures its CLI measurement report, at least in part, to include indications of estimated propagation delay between base station DU 1405-1 and base station DU 1405-2, based on CLI measurement report configuration.

[0188] In some aspects, base station DU 1405-1 configures its CLI measurement report, at least partially based on CLI measurement report configuration, to include an indication of the estimated RTT between base station DU 1405-1 and base station DU 1405-2. In some aspects, base station DU 1405-1 configures its CLI measurement report, at least partially based on CLI measurement report configuration, to include an indication of the interference level category (e.g., low, medium, or high) of base station DU 1405-2. In some aspects, base station DU 1405-1 configures its CLI measurement report, at least partially based on CLI measurement report configuration, to include an indication of a specific number of the strongest aggressor cells (e.g., K strongest aggressor cells) of base station DU 1405-2. In some aspects, base station DU 1405-1 configures its CLI measurement report, at least partially based on CLI measurement report configuration, to include an indication of a specific number of the weakest aggressor cells (e.g., M weakest aggressor cells) of base station DU 1405-2. In some respects, base station DU 1405-1 configures CLI measurement reports to include indications of a specific number of cells selected by base station DU 1405-2, at least in part based on CLI measurement report configuration.

[0189] In some aspects, base station DU 1405-1 configures its CLI measurement report to include indications of one or more recommended parameters for mitigating, reducing, and / or eliminating inter-DU CLI between base station DU 1405-1 and base station DU 1405-2 for itself and / or base station DU 1405-2. The one or more recommended parameters may include, for example, power adjustment parameters for itself and / or base station DU 1405-2 for various time-domain and / or frequency-domain resources and / or various spatial directions. As another example, the one or more recommended parameters may instruct base station DU 1405-2 to avoid transmitting communication in specific time-domain and / or frequency-domain resources and / or in specific spatial directions. As another example, the one or more recommended parameters may indicate specific time-domain and / or frequency-domain resources and / or specific spatial directions on which base station DU 1405-1 should avoid any communication. As another example, one or more recommended parameters may indicate the resources and / or configuration of one or more reference signals to be transmitted by base station DU 1405-1 and / or base station DU 1405-2 (e.g., to make the reference signals associated with different DUs orthogonal). As another example, one or more recommended parameters may indicate the timing adjustments associated with base station DU 1405-1 and / or base station DU 1405-2 (e.g., to align the timing of communications associated with the two base station DUs).

[0190] As another example, one or more recommended parameters may indicate a recommended reference signal configuration to make the reference signals transmitted by base stations DU 1405-1 and DU 1405-2 orthogonal. As another example, one or more recommended parameters may indicate timing adjustment suggestions to align the timing of multiple communications in the same direction for base stations DU 1405-1 and DU 1405-2 (e.g., to align uplink communications for base stations DU 1405-1 and DU 1405-2, and / or to align downlink communications for base stations DU 1405-1 and DU 1405-2).

[0191] As in Figure 14 As further shown by reference numeral 1435, base station DU 1405-1 can send CLI measurement reports to base station CU 1410 (and in some cases, to base station DU 1405-2 and / or OAM component 1415). In some aspects, base station DU 1405-1 sends periodic CLI measurement reports, event-triggered CLI measurement reports, semi-persistent CLI measurement reports, or dynamic CLI measurement reports, at least in part based on CLI measurement report configuration. In some aspects, base station DU 1405-1 can send CLI measurement reports from resources indicated in the CLI measurement report configuration used for sending CLI measurement reports.

[0192] As noted above, base stations DU 1405-1, DU 1405-2, and / or CU 1410 may be included in the IAB network. In some aspects, base station DU 1405-1 sends CLI measurement reports to base station CU 1410 (which may be part of an IAB donor associated with an IAB node that includes base station DU 1405-1). In some aspects, base station DU 1405-1 sends CLI measurement reports to base station CU associated with base station DU 1405-2. In some aspects, base station DU 1405-1 sends CLI measurement reports directly to base station DU 1405-2 between IAB nodes (e.g., between an IAB parent node and an IAB child node). In these examples, base station DU 1405-1 can be associated with the IAB parent node and base station DU 1405-2 can be associated with the IAB child node, or base station DU 1405-2 can be associated with the IAB parent node and base station DU 1405-1 can be associated with the IAB child node.

[0193] As in Figure 14As further shown by reference numeral 1440, base station CU 1410 can be configured for communication between base station DU 1405-1, base station DU 1405-2, and / or one or more other nodes in the wireless network to reduce, mitigate, and / or eliminate inter-DU CLI between base station DU 1405-1 and base station DU 1405-2. For example, base station CU 1410 can align the transmission schedule of base station DU 1405-1 with the transmission schedule of cells associated with base station DU 1405-2 that has performed one or more CLI measurements. As another example, base station CU 1410 can align the reception schedule of base station DU 1405-1 with the reception schedule of cells associated with base station DU 1405-2 that has performed one or more CLI measurements. As another example, base station CU 1410 can combine the TDD configuration of base station DU 1405-1 with the TDD configuration of the cell associated with base station DU1405-2 that has performed one or more CLI measurements, so that base station DU 1405-1 and base station DU 1405-2 transmit and / or receive at similar times.

[0194] As another example, base station CU 1410 may instruct base station DU 1405-1 to adjust the transmit power of one or more UEs 120 and / or one or more IAB sub-nodes of IAB nodes associated with base station DU 1405-1. As another example, base station CU 1410 may coordinate spatial resources for the cell of base station DU 1405-1 and base station DU 1405-2 that has performed one or more CLI measurements. As another example, base station CU 1410 may schedule base station DU 1405-1 to transmit URLLC as uplink communication or URLLC as downlink communication during scheduled transmit resources (e.g., scheduled uplink transmit resources or scheduled downlink transmit resources) of the cell associated with base station DU 1405-2 that has performed one or more CLI measurements.

[0195] As pointed out above, Figure 14 This is provided as one or more examples. Other examples may differ from those provided. Figure 14 The example described.

Figure 15As shown, Example 1500 includes communication between multiple wireless network nodes (e.g., multiple base stations DU 1505 (e.g., base station DU 1505-1 and base station DU 1505-2) and multiple base stations CU 1510 (e.g., base station CU 1510-1 and base station CU 1510-2)). In some aspects, the nodes may be included in a wireless network (e.g., wireless network 100).

[0197] Base station DU 1505 can implement, can be implemented by, and / or can be associated with: base station 110, TRP 308, DU 406, DU of non-anchor base station 545, DU of IAB node 610, DU 705, upstream node 710, downstream node 715, and / or Figure 18 The device 1800. The base station CU 1510 can implement, can be implemented by, and / or can be associated with: base station 110, ANC 302, C-RU 404, anchor base station 535, IAB donor 605, upstream node 710, and / or Figure 19 The device 1900.

[0198] In some respects, base stations DU 1505 and CU 1510 are non-IAB nodes. In other respects, base stations DU 1505 and / or CU 1510 are included in the IAB network (e.g., in conjunction with the above). Figure 5 and / or Figure 6 In one or more IAB networks shown and described. In these examples, base stations DU 1505-1 and DU 1505-2 may be associated with different IAB nodes, and base stations CU 1510-1 and CU 1510-2 may be associated with different IAB donors.
