Description

Technical Field

[0001] Aspects of the present disclosure relate generally to wireless communications and to techniques and apparatus for reporting cross-link interference associated with electromagnetic radiation reflection relay services. Background Art

[0002] Wireless communication systems are widely deployed to provide a variety of telecommunication services, such as telephony, video, data, messaging, and broadcasting. Typical wireless communication systems may employ multiple access technologies that can support 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 / LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP).

[0003] A wireless network may include one or more base stations that support communications for a user equipment (UE) or multiple UEs. A UE may communicate with a base station via downlink communications and uplink communications. A "downlink" (or "DL") refers to the communication link from a base station to a UE, and an "uplink" (or "UL") refers to the communication link from a UE to a base station.

[0004] The above-mentioned multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different UEs to communicate at a city, country, region and / or global level. New Radio (NR), which may be referred to as 5G, is a set of enhancements to the LTE mobile standard promulgated by 3GPP. NR is designed to better support mobile broadband Internet access by improving spectrum efficiency, reducing costs, improving services, utilizing new spectrum, and using orthogonal frequency division multiplexing (OFDM) with cyclic prefix (CP) (CP-OFDM) on the downlink, using CP-OFDM and / or single carrier frequency division multiplexing (SC-FDM) (also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink to better integrate with other open standards, as well as supporting beamforming, multiple input multiple output (MIMO) antenna technology and carrier aggregation. As the demand for mobile broadband access continues to increase, further improvements in LTE, NR and other radio access technologies remain useful. Summary of the invention

[0037] In general, any number of networks 108 may be deployed in a given geographic area. Each network 108 may support a specific radio access technology (RAT) and may operate on one or more frequencies. RAT may be referred to as a radio technology, air interface, etc. Frequency may be referred to as a carrier, frequency channel, etc. Each frequency may support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, an open RAT, new radio (NR) or 5G RAT network may be deployed.

[0038] In some aspects, environment 100 may include one or more non-terrestrial network (NTN) deployments, where non-terrestrial wireless communication devices may include network nodes.

[0039] One or more of network nodes 102, 104 and 106 may be any number of non-terrestrial wireless communication devices, include any number of non-terrestrial wireless communication devices, or be included in any number of non-terrestrial wireless communication devices.

Additionally or alternatively, network node 102 and / or network node 106 may include one or more apparatuses 200 and / or one or more components of apparatus 200. For example, in some aspects, apparatus 200 may include an apparatus (e.g., a device, a device component, a modem, a chip, and / or a collection of device components, etc.) configured to perform a wireless communication method at a network node, as described herein. Figure 2 As shown, device 200 may include components such as bus 205, processor 210, memory 215, input component 220, output component 225, communication interface 230, communication manager 235, and reference signal processing component 240. Any one or more of components 205, 210, 215, 220, 225, 230, 235, and / or 240 may be implemented in hardware, software, or a combination of hardware and software.

[0048] The bus 205 includes components that permit communication between the components of the device 200. The processor 210 includes a central processing unit (CPU), a graphics processing unit (GPU), an accelerated processing unit (APU), a digital signal processor (DSP), a microprocessor, a microcontroller, a field programmable gate array (FPGA), an application specific integrated circuit (ASIC), and / or another type of processing component. In some aspects, the processor 210 includes one or more processors that can be programmed to perform functions.

[0049] The memory 215 includes random access memory (RAM), read-only memory (ROM), and / or another type of dynamic or static storage device (e.g., flash memory, magnetic memory, and / or optical memory) that stores information and / or instructions for use by the processor 210. The memory 215 may store other information and / or software related to the operation and use of the device 200. For example, the memory 215 may include a hard disk (e.g., a magnetic disk, an optical disk, a magneto-optical disk, and / or a solid-state disk), a compact disk (CD), a digital versatile disk (DVD), a floppy disk, a cassette, a magnetic tape, and / or another type of non-transitory computer-readable medium.

[0050] Input component 220 includes components that allow device 200 to receive information, such as via user input. For example, input component 220 may be associated with a user interface as described herein (e.g., to allow a user to interact with one or more features of device 200). Input component 220 may include a capacitive touch screen display that can receive user input. Input component 220 may include a keyboard, a keypad, a mouse, a button, a switch, and / or a microphone, etc. Additionally or alternatively, input component 220 may include a sensor for sensing information (e.g., a visual sensor, a position sensor, an accelerometer, a gyroscope, and / or an actuator, etc.). In some aspects, input component 220 may include a camera (e.g., a high-resolution camera and / or a low-resolution camera, etc.). Output component 225 may include a component that provides an output from device 200 (e.g., a display, a speaker, and / or one or more light-emitting diodes (LEDs), etc.).

[0051] The communication interface 230 may include a transmitting component and / or a receiving component. For example, the communication interface 230 includes a transceiver and / or one or more separate receivers and transmitters that enable the device 200 to communicate with other devices (such as via a wired connection, a wireless connection, or a combination of a wired connection and a wireless connection). In some aspects, the communication interface may include one or more radio frequency reflective elements and / or one or more radio frequency refractive elements. The communication interface 230 may allow the device 200 to receive information from another device and / or provide information to another device. For example, the communication interface 230 may include an Ethernet interface, an optical interface, a coaxial interface, an infrared interface, an RF interface, a universal serial bus (USB) interface, a Wi-Fi interface, a cellular network interface, a wireless modem, an integrated circuit bus (ICB), or a wireless bus. 2 C) and / or Serial Peripheral Interface (SPI), etc.

[0052] The communication manager 235 may include hardware, software, or a combination of hardware and software configured to cause the apparatus 200 to perform one or more communication tasks associated with the communication manager 110, the transceiver 112, the communication manager 114, and / or the transceiver 116. In some aspects, the communication manager 235 may be Figure 1 In some aspects, the communication manager 235 may include the processor 210, the memory 215, the input component 220, the output component 225, the communication interface 230, and / or the reference signal processing component 240, and / or one or more aspects thereof.

[0053] As indicated above, Figure 2 are provided as examples. Other examples can be found in the Figure 2 Different than described.

[0054] As mentioned above, in some aspects, Figure 1 The network 108 depicted in the figure may include a cellular network that includes a RAT. Although some aspects may be described herein using terms generally associated with 5G or NR RAT, aspects of the present disclosure may be applied to other RATs, such as 3G RAT, 4G RAT, and / or RATs beyond 5G (e.g., 6G).

[0055] Figure 3 3 is a diagram illustrating an example of a wireless network 300 according to the present disclosure. The wireless network 300 may be or may include elements of a 4G (e.g., LTE) network, a 5G (e.g., NR) network, and / or a 6G network, etc. The wireless network 300 may include one or more base stations 310 (individually illustrated as BS 310a, BS 310b, BS 310c, and BS 310d), one UE 320 or multiple UEs 320 (individually illustrated as UE 320a, UE 320b, UE 320c, UE 320d, and UE 320e), and / or other network entities. The base station 310 is an entity that communicates with the UE 320. The base station 310 may include, for example, an NR base station, an LTE base station, a Node B, an eNB (e.g., in 4G), a gNB (e.g., in 5G), an access point, and / or a transmit receive point (TRP). Each base station 310 may provide communication coverage for a specific geographic area. In the 3rd Generation Partnership Project (3GPP), the term "cell" can refer to the coverage area of ​​a base station 310 and / or a base station subsystem serving the coverage area, depending on the context in which the term is used.

[0056] The base station 310 may provide communication coverage for a macro cell, a pico cell, a femto cell, and / or another type of cell. A macro cell may cover a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access by a UE 320 with a service subscription. A pico cell may cover a relatively small geographic area and may allow unrestricted access by a UE 320 with a service subscription. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by a UE 320 associated with the femto cell (e.g., a UE 320 in a closed subscriber group (CSG)). A base station 310 for a macro cell may be referred to as a macro base station. A base station 310 for a pico cell may be referred to as a pico base station. A base station 310 for a femto cell may be referred to as a femto base station or a home base station. In Figure 3In the example shown, BS 310a may be a macro base station for macro cell 302a, BS 310b may be a pico base station for pico cell 302b, and BS 310c may be a femto base station for femto cell 302c. A base station may support one or more (eg, three) cells.

[0057] In some examples, the cell may not necessarily be stationary, and the geographic area of ​​the cell may move depending on the location of the mobile base station 310 (e.g., a mobile base station). In some examples, the base stations 310 may be interconnected with each other and / or to one or more other base stations 310 or network nodes (not shown) in the wireless network 300 using any suitable transport network through various types of backhaul interfaces (such as direct physical connections or virtual networks).

[0058] The wireless network 300 may include one or more relay stations. A relay station is an entity that can receive transmissions of data from an upstream station (e.g., a base station 310 or a UE 320) and transmit transmissions of data to a downstream station (e.g., a UE 320 or a base station 310). A relay station may be a UE 320 that is capable of relaying transmissions for other UEs 320. Figure 3 In the example shown, BS 310d (eg, a relay base station) can communicate with BS 310a (eg, a macro base station) and UE 320d to facilitate communication between BS 310a and UE 320d. A base station 310 that relays communications may be referred to as a relay station, relay base station, relay, or the like.

[0059] The wireless network 300 may be a heterogeneous network including different types of base stations 310, such as macro base stations, pico base stations, femto base stations, relay base stations, etc. These different types of base stations 310 may have different transmit power levels, different coverage areas, and / or different impacts on interference in the wireless network 300. For example, a macro base station may have a high transmit power level (e.g., 5 watts to 40 watts), while a pico base station, a femto base station, and a relay base station may have a lower transmit power level (e.g., 0.1 watt to 2 watts).

[0060] The network controller 330 may be coupled to or communicate with a set of base stations 310, and may provide coordination and control for the base stations 310. The network controller 330 may communicate with the base stations 310 via a backhaul communication link. The base stations 310 may also communicate directly with each other, or indirectly via a wireless or wired backhaul communication link. For example, in some aspects, the wireless network 300 may be, include, or be included in a wireless backhaul network, which is sometimes referred to as an IAB network. In an IAB network, at least one base station (e.g., base station 310) may be an anchor base station that communicates with a core network via a wired backhaul link (such as a fiber optic connection). An anchor base station may also be referred to as an IAB donor (or IAB-donor), a central entity, a central unit, and the like. An IAB network may include one or more non-anchor base stations (sometimes referred to as relay base stations or IAB nodes (or IAB-nodes)). The non-anchor base station may communicate directly or indirectly with the anchor base station via one or more backhaul links (e.g., via one or more non-anchor base stations) to form a backhaul path to the core network for carrying backhaul traffic. The backhaul link may be a wireless link. The anchor base station and / or the non-anchor base station may communicate with one or more UEs (e.g., UE 320) via an access link (which may be a wireless link for carrying access traffic).

[0061] In some aspects, a radio access network including an IAB network may utilize millimeter wave technology and / or directional communication (e.g., beamforming, precoding, 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 wireless backhaul link between base stations may use millimeter waves to carry information and / or may use beamforming, precoding, etc. to be directed toward a target base station. Similarly, a wireless access link between a UE and a base station may use millimeter waves and / or may be directed toward a target wireless node (e.g., a UE and / or a base station). In this way, inter-link interference may be reduced.

[0062] The IAB network may include an IAB donor connected to the core network via a wired connection (e.g., wired backhaul). For example, the Ng interface of the IAB donor may terminate at the core network. Additionally or alternatively, the IAB donor may be connected to one or more devices of the core network, which provide a core access and mobility management function (AMF). In some aspects, the IAB donor may include a base station 310 (such as an anchor base station). The IAB donor may include a central unit that may perform access node controller (ANC) functions and / or AMF functions. The central unit may configure the DU of the IAB donor and / or may configure one or more IAB nodes (e.g., mobile terminal (MT) functions and / or DU functions of IAB nodes) connected to the core network via the IAB donor. Therefore, the central unit of the IAB donor may control and / or configure the entire IAB network (or a portion thereof) connected to the core network via the IAB donor, such as by using control messages and / or configuration messages (e.g., radio resource control (RRC) configuration messages or F1 application protocol (F1AP) messages).

[0063] The MT function of an IAB node (e.g., a child node) may be controlled and / or scheduled by another IAB node (e.g., a parent node of the child node) and / or by an IAB donor. The DU function of an IAB node (e.g., a parent node) may control and / or schedule other IAB nodes (e.g., child nodes of the parent node) and / or UE 320. Therefore, DU may be referred to as a scheduling node or a scheduling component, and MT may be referred to as a scheduled node or a scheduled component. In some aspects, an IAB donor may include a DU function without an MT function. That is, an IAB donor may configure, control and / or schedule the communication of an IAB node and / or UE 320. UE 320 may include only an MT function without a DU function. That is, the communication of UE 320 may be controlled and / or scheduled by an IAB donor and / or an IAB node (e.g., a parent node of UE 320).

[0064] When a first node controls and / or schedules the communication of a second node (e.g., when the first node provides a DU function for the MT function of the second node), the first node may be referred to as the parent node of the second node, and the second node may be referred to as the child node of the first node. The child node of the second node may be referred to as the grandchild node of the first node. Thus, the DU function of the parent node may control and / or schedule the communication of the child node of the parent node. The parent node may be an IAB donor or an IAB node, and the child node may be an IAB node or a UE 320. The communication of the MT function of the child node may be controlled and / or scheduled by the parent node of the child node.

[0065] The link between UE 320 and the IAB donor or between UE 320 and the IAB node may be referred to as an access link. The access link may be a wireless access link that provides radio access to the core network to UE 320 via the IAB donor and optionally via one or more IAB nodes. Therefore, wireless network 300 may be referred to as a multi-hop network or a wireless multi-hop network.

[0066] The link between an IAB donor and an IAB node or between two IAB nodes may be referred to as a backhaul link. The backhaul link may be a wireless backhaul link, which provides radio access to a core network to the IAB node via the IAB donor and optionally via one or more other IAB nodes. In an IAB network, network resources (e.g., time resources, frequency resources, and / or space resources) for wireless communication may be shared between an access link and a backhaul link. In some aspects, the backhaul link may be a primary backhaul link or an auxiliary backhaul link (e.g., a standby backhaul link). In some aspects, if the primary backhaul link fails, becomes congested and / or becomes overloaded, etc., an auxiliary backhaul link may be used.

[0067] UE 320 can be dispersed throughout the wireless network 300, and each UE 320 can be stationary or mobile. UE 320 can include, for example, access terminals, terminals, mobile stations and / or subscriber units. UE 320 can be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet computer, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device, a biometric device, a wearable device (e.g., a smart watch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring or a smart bracelet)), an entertainment device (e.g., a music device, a video device and / or a satellite radio), a vehicle component or sensor, a smart meter / sensor, an industrial manufacturing equipment, a global positioning system device and / or any other suitable device configured to communicate via a wireless medium.

[0068] Some UE 320 may be considered as machine type communication (MTC) or evolved or enhanced machine type communication (eMTC) UE. MTC UE and / or eMTC UE may include, for example, a robot, a drone, a remote device, a sensor, a meter, a monitor and / or a location tag, which may communicate with a base station, another device (e.g., a remote device) or some other entity. Some UE 320 may be considered as an Internet of Things (IoT) device and / or may be implemented as a NB-IoT (narrowband IoT) device. Some UE 320 may be considered as customer site equipment. UE 320 may be included in a housing that houses components of UE 320, such as a processor component and / or a memory component. In some examples, the processor component and the memory component may be coupled together. For example, a processor component (e.g., one or more processors) and a memory component (e.g., a memory) may be operationally coupled, communicatively coupled, electronically coupled and / or electrically coupled.

[0069] Generally speaking, any number of wireless networks 300 may be deployed in a given geographic area. Each wireless network 300 may support a specific RAT and may operate on one or more frequencies. RAT may be referred to as a radio technology, air interface, etc. Frequency may be referred to as a carrier, frequency channel, etc. Each frequency may support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed.

[0070] In some examples, two or more UEs 320 (e.g., shown as UE 320a and UE 320e) may communicate directly (e.g., without using base station 310 as an intermediary to communicate with each other) using one or more side link channels. For example, UE 320 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, vehicle-to-infrastructure (V2I) protocols, or vehicle-to-pedestrian (V2P) protocols) and / or mesh networks. In such examples, UE 320 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by base station 310.

[0071] The devices of the wireless network 300 may communicate using an electromagnetic spectrum, which may be subdivided into various categories, bands, channels, etc., according to frequency or wavelength. For example, the devices of the wireless network 300 may communicate using one or more operating bands. In 5G NR, two initial operating bands have been identified as frequency ranges designated FR1 (410 MHz–7.125 GHz) and FR2 (24.25 GHz–52.6 GHz). It should be understood that, although a portion of FR1 is greater than 6 GHz, FR1 is often (interchangeably) referred to as a “below 6 GHz” band in various documents and articles. A similar naming problem sometimes occurs with respect to FR2, which is often (interchangeably) referred to as a “millimeter wave” band in documents and articles, although different from the extremely high frequency (EHF) band (30 GHz–300 GHz) identified as a “millimeter wave” band by the International Telecommunication Union (ITU).

[0072] Frequencies between FR1 and FR2 are generally referred to as mid-band frequencies. Recent 5G NR research has identified the operating bands for these mid-band frequencies as frequency range designation FR3 (7.125 GHz–24.25 GHz). The bands falling within FR3 can inherit FR1 characteristics and / or FR2 characteristics, and thus the features of FR1 and / or FR2 can be effectively extended to mid-band frequencies. In addition, higher frequency bands are currently being explored to extend 5G NR operations to more than 52.6 GHz. For example, three higher operating bands have been identified as frequency range designations FR4a or FR4-1 (52.6 GHz–71 GHz), FR4 (52.6 GHz–114.25 GHz), and FR5 (114.25 GHz–300 GHz). Each of these higher frequency bands falls within the EHF band.

[0073] Considering the above examples, unless otherwise explicitly stated, it should be understood that if the term "below 6 GHz" or the like is used herein, the term may broadly refer to frequencies that may be lower than 6 GHz, may be within FR1, or may include mid-band frequencies. In addition, unless otherwise explicitly stated, it should be understood that if the term "millimeter wave" or the like is used herein, the term may broadly refer to frequencies that may include mid-band frequencies, may be within FR2, FR4, FR4-a or FR4-1, and / or FR5, or may be within the EHF band. It is contemplated that the frequencies included in these operating bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, and / or FR5) may be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0074] As described above, in some aspects, a network node (e.g., Figure 1The network nodes 102, 104, and / or the network nodes 106 depicted in the figure may be implemented in a wireless communication environment. For example, in some aspects, the network nodes may be implemented as UEs (e.g., UE 320a), base stations (e.g., base station 310a), relay devices, and / or TRPs, etc. In some such aspects, as Figure 3 As shown, UE 320a may include a communication manager 340 and / or a transceiver 345, and base station 310a may include a communication manager 350 and / or a transceiver 355. In some aspects, communication managers 340 and / or 350 may be Figure 1 The communication manager 110 and / or 114 and / or Figure 2 235, similar to, including, or included in the communications manager 235 depicted in FIG. 236. In some aspects, transceivers 345 and / or 355 may be Figure 1 In some aspects, transceivers 345 and / or 355 may be similar to, include, or be included in transceivers 112 and / or 116 depicted in FIG. Figure 2 The communication interface 230 depicted in , is similar to, includes, or is included in the communication interface.

[0075] As indicated above, Figure 3 are provided as examples. Other examples can be found in the Figure 3 Different than described.

[0076] Figure 4 is an example of a method according to the present disclosure including wireless communication with network node 404 (eg, via a communication device such as Figure 1 The network 108 depicted in FIG. 1 and / or Figure 3 3. The wireless network 300 depicted in FIG. 2 is a diagram of an environment 400 of a network node 402 of the wireless network 300 depicted in FIG. 2. The network node 402 may be equipped with a set of antennas 406a to 406t, such as T antennas (T ≥ 1). The network node 404 may be equipped with a set of antennas 408a to 408r, such as R antennas (R ≥ 1).

[0077] At the network node 402, a transmit processor 410 may receive data intended for the network node 404 (or a set of network nodes 404) from a data source 412. The transmit processor 410 may select one or more modulation and coding schemes (MCS) for the network node 404 based on one or more channel quality indicators (CQIs) received from the network node 404. The network node 402 may process (e.g., encode and modulate) the data for the network node 404 based on the MCS selected for the network node 404 and provide data symbols for the network node 404. The transmit processor 410 may process system information (e.g., for semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper layer signaling), and provide overhead symbols and control symbols. The transmit processor 410 may 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 signals (PSS) or secondary synchronization signals (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 414 may perform spatial processing (e.g., pre-coding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, where applicable, and may provide a set of output symbol streams (e.g., T output symbol streams) to a corresponding set of modems 416a to 416t (e.g., T modems). For example, each output symbol stream may be provided to a modulator component (shown as MOD) of a modem in the set of modems 416a to 416t. Each modem in the set of modems 416a to 416t may process a corresponding output symbol stream (e.g., for OFDM) using a corresponding modulator component to obtain an output sample stream. Each modem in the set of modems 416a to 416t may further process the output sample stream (e.g., convert to analog, amplify, filter, and / or upconvert) using a corresponding modulator component to obtain a signal. One or more modems in the set of modems 416a to 416t may transmit a set of signals (e.g., T signals) via a corresponding antenna in the set of antennas 406a to 406t. The signal may include, for example, a downlink signal.

[0078] At the network node 404, one or more antennas in the set of antennas 408a to 408r may receive signals from the network node 402 and / or multiple network nodes, and may provide a set of received signals (e.g., R received signals) to one or more modems in the set of modems 418a to 418r (e.g., R modems). For example, each received signal may be provided to a modulator component (shown as DEMOD) of a corresponding modem in the set of modems 418a to 418r. Each modem in the set of modems 418a to 418r may use a corresponding demodulator component to condition (e.g., filter, amplify, downconvert and / or digitize) the received signal to obtain input samples. Each modem in the set of modems 418a to 418r may use a demodulator component to further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector 420 may obtain received symbols from each one or more modems in the set of modems 418a to 418r, may perform MIMO detection on the received symbols where applicable, and may provide detected symbols.

[0079] The receive processor 422 may process (e.g., demodulate and decode) the detected symbols, may provide decoded data for the network node 404 to a data sink 424, and may provide decoded control information and system information to a controller / processor 426. The term "controller / processor" may refer to one or more controllers, one or more processors, or a combination thereof. The controller / processor 426 may be a processor that is operable to receive and transmit signals to the network node 404. Figure 2 Controller / processor 426 may be configured to include, be similar to, include, or be included in processor 210 depicted in . Controller / processor 426 may determine, among other things, a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, and / or a CQI parameter.

[0080] The network controller 428 may include a communication unit 430, a controller / processor 432, and a memory 434. The network controller 428 may be Figure 3 4. The network controller 428 may be similar to, include, or be included in the network controller 330 depicted in FIG. 4. The network controller 428 may include, for example, one or more devices in a core network. The network controller 428 may communicate with the network node 402 via a communication unit 430.

[0081] One or more antennas (e.g., antennas 406a to 406t and / or antennas 408a to 408r) may include or be included within one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, and / or one or more antenna arrays, etc. Antenna panels, antenna groups, sets of antenna elements, and / or antenna arrays may include one or more antenna elements (within a single housing or multiple housings), sets of coplanar antenna elements, sets of non-coplanar antenna elements, and / or coupled to one or more transmit and / or receive components (such as, Figure 4 One or more antenna elements of one or more components in.

[0082] Similarly, at the network node 404, a transmit processor 436 may receive and process data from a data source 438 and control information from a controller / processor 426 (e.g., for reports including RSRP, RSSI, RSRQ, and / or CQI). The transmit processor 436 may generate reference symbols for one or more reference signals. The symbols from the transmit processor 436 may be pre-decoded by the TX MIMO processor 440, where applicable, and further processed by one or more modems in the set of modems 418a to 418r (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to the network node 402. In some examples, each modem in the set of modems 418a to 418r of the network node 404 may include a modulator and a demodulator. In some examples, the network node 404 includes a transceiver.

[0088] Although Figure 4 The blocks in the 4000 are illustrated as distinct components, but the functionality described above for these blocks may be implemented in a single hardware, software, or combined component or in various combinations of components. For example, the functionality described for the transmit processor 436, the receive processor 422, and / or the TX MIMO processor 440 may be performed by or under the control of the controller / processor 426. Figure 4 Any number of other combinations of the various combinations of components depicted are possible within the scope of the present disclosure.

[0089] As indicated above, Figure 4 are provided as examples. Other examples can be found in the Figure 4 Different than described.

[0090] Figure 5 5 is a diagram illustrating an example 500 of an O-RAN architecture according to the present disclosure. Figure 5As shown, the O-RAN architecture may include a CU 510 that communicates with a core network 520 via a backhaul link. In addition, the CU 510 may communicate with one or more DUs 530 via corresponding midhaul links. The DUs 530 may each communicate with one or more RUs 540 via corresponding fronthaul links, and the RUs 540 may each communicate with a corresponding UE 320 via an RF access link. The DU 530 and the RU 540 may also be referred to as O-RAN DU (O-DU) 530 and O-RAN RU (O-RU) 540, respectively.

[0091] In some aspects, the DU 530 and the RU 540 may be implemented according to a functional split architecture, wherein the functionality of a base station 310 (e.g., an eNB or gNB) is provided by the DU 530 and one or more RUs 540 that communicate via a fronthaul link. Thus, as described herein, a base station 310 may include a DU 530 and one or more RUs 540 that may be co-located or geographically distributed. In some aspects, the DU 530 and associated RUs 540 may communicate via a fronthaul link to exchange real-time control plane information via a lower layer split (LLS) control plane (LLS-C) interface, non-real-time management information via an LLS management plane (LLS-M) interface, and / or user plane information via an LLS user plane (LLS-U) interface.

[0092] Thus, the DU 530 may correspond to a logical unit that includes one or more base station functions to control the operation of one or more RUs 540. For example, in some aspects, the DU 530 may host a radio link control (RLC) layer, a medium access control (MAC) layer, and one or more higher-level physical (PHY) layers (e.g., forward error correction (FEC) encoding and decoding, scrambling, and / or modulation and demodulation) based on the lower-layer functional separation. Higher-layer control functions such as packet data convergence protocol (PDCP), RRC, and / or service data adaptation protocol (SDAP) may be hosted by the CU 510. Based on the lower-layer functional split, the RU 540 controlled by the DU 530 may correspond to a logical node that hosts RF processing functions and low PHY layer functions (e.g., fast Fourier transform (FFT), inverse FFT (iFFT), digital beamforming, and / or physical random access channel (PRACH) extraction and filtering). Thus, in the O-RAN architecture, the RU 540 handles all over-the-air (OTA) communications with the UE 320, and the real-time and non-real-time aspects of the control plane and user plane communications with the RU 540 are controlled by the corresponding DU 530, which enables the DU 530 and the CU 510 to be implemented in a cloud-based RAN architecture.

[0093] As indicated above, Figure 5are provided as examples. Other examples can be found in the Figure 5 Different than described.

[0094] Figure 6 600 is a diagram illustrating an example of wireless communication according to the present disclosure. As shown, a first network node 602 and a second network node 604 may communicate via a communication channel 606. An electromagnetic radiation reflection relay network node 608 (shown as a "reflection network node") may be used to relay a signal from the network node 602 to the network node 604 via a communication channel 610. The electromagnetic radiation reflection relay network node 608 may include, for example, a radio frequency reflection array configured to perform a radio frequency reflection service. The electromagnetic radiation reflection relay network node 608 may be, for example, a reconfigurable intelligent surface (RIS) (which may also be referred to as an intelligent reflective surface (IRS)).

[0095] As shown, for example, network node 602 may send a signal to electromagnetic radiation reflection relay network node 608 via communication channel 612, and the electromagnetic radiation reflection relay network node may relay the signal to network node 604 via communication channel 610. In some cases, electromagnetic radiation reflection relay network node 608 may relay transmissions between network node 602 and network node 614. For example, as shown, network node 602 may send a signal to electromagnetic radiation reflection relay network node 608 via communication channel 612, and the electromagnetic radiation reflection relay network node may relay the signal to network node 614 via communication channel 616.

[0096] like Figure 6 As shown, the electromagnetic radiation reflection relay network node 608 may include a collection of reflective elements 618 disposed adjacent to a ground plane 620. Each reflective element 618 may be coupled to a phase shift component 622, and each phase shift component 622 may be coupled to a corresponding ground component 624. In some aspects, each reflective element 618 may be coupled to two phase shift components 622, one for each polarization. In some aspects, one or more reflective elements 618 may be driven by a power amplifier 626. The power amplifier 626 may be coupled to a power supply 628 and may be controlled by a controller 630. In some cases, for example, the power amplifier 626 may be configured to provide just enough power to offset the energy loss caused by the reflection of the signal and / or its phase adjustment. In some cases, the complexity of the controller 630 and / or the power consumption of the power amplifier 626 may be based on the selection of the phase shift component 622. In some cases, the electromagnetic radiation reflection relay network node 608 may be configured to reflect a signal 632 (e.g., a signal transmitted via the communication channel 612) by beamforming the reflected signal 634 (e.g., a signal transmitted via the communication channel 616) to direct the reflected signal 634 based on one or more beams 636.

[0097] In some cases, as shown, network node 602 may send a signal to network node 614 via communication channel 638 without using electromagnetic radiation reflection relay network node 608 as a relay. Network node 614 may send a signal to network node 604 via communication channel 640. In some cases, network node 614 may send a signal to electromagnetic radiation reflection relay network node 608 via communication channel 642, and the electromagnetic radiation reflection relay network node may relay the signal to network node 604 via communication channel 610. In some cases, network node 614 may send configuration information to electromagnetic radiation reflection relay network node 608 via communication channel 644 to configure one or more aspects of the operation of electromagnetic radiation reflection relay network node 608.

[0098] In such Figure 6 In the communication scenario of the scenario depicted in , CLI may hinder the efficiency and accuracy of communication. CLI is interference from one entity to another nearby entity. For example, when the network configures different time domain duplex (TDD) UL and DL time slot formats for nearby UEs, CLI may occur between two network nodes (such as UEs). When a network node (e.g., network node 602) (which may be referred to as an aggressor network node) is transmitting, if the UL symbol of the aggressor network node collides with at least one DL symbol of the victim network node, the other network node (e.g., network node 604) (which may be referred to as a victim network node) may receive the transmission as CLI in its DL symbol. Figure 6 As shown, the attacker network node 602 may communicate with the attacker via channel 638 (which may be indicated as “h A-g ”) communicates with network node 614. The attacker network node 602 may communicate with the network node 614 via channel 606 (which may be indicated as “h A-V ”) in the CLI interference victim network node 604. In some cases, the electromagnetic radiation reflection relay network node 608 may be configured to make the channel 616 (which may be indicated as “h A-I-g ”) to maximize the channel strength. The attacker network node 602 may also communicate with the reflected channel 610 (which may be indicated as “h A-I-V ”) interferes with the victim network node 604. In some cases, the victim network node 604 may measure the CLI from the aggressor network node 602. For example, if the network configures one or more CLI measurement resources to measure CLI, the victim network node 604 may measure CLI. CLI measurement is defined as a periodic measurement based on sounding reference signal (SRS) RSRP or RSSI. CLI may reduce the effectiveness of communication, thereby negatively affecting network performance.

[0099] Some techniques and apparatus described herein provide for the measurement of CLI associated with an electromagnetic radiation reflecting relay network node and the mitigation of CLI based on these measurements. For example, in some aspects, the network node 604 may receive a signal (which may be indicated as “y T1 ”), the signal includes a signal corresponding to the first communication channel h between the network node 604 and the network node 602 A-V (eg, communication channel 606) a first pre-coding vector c 11 The first signal characteristic associated with A-V c 11 s”), and a second pre-coding vector c corresponding to a second communication channel (eg, communication channel 610) between the network node 604 and the electromagnetic radiation reflection relay network node 12 The associated second signal characteristic (which may be indicated as “h A-I-V c 12 s”). The network node 604 may send channel estimation information corresponding to the signal, and the network node 614 may receive channel estimation information corresponding to the signal. The channel estimation information may include first channel estimation information and second channel estimation information. The first channel estimation information corresponds to the first communication channel and is based on the first precoding vector, and the second channel estimation information corresponds to the second communication channel and is based on the second precoding vector.

[0100] In some aspects, the network node 614 sends reflection relay configuration information to the electromagnetic radiation reflection relay network node 608. The reflection relay configuration information may indicate one or more electromagnetic reflection parameters based on the channel estimation information. In some aspects, the electromagnetic radiation reflection relay network node 608 may be used to manipulate and / or add signal propagation paths to mitigate CLI effects. For example, in some aspects, the reflection relay configuration information may be used to configure the electromagnetic radiation reflection relay network node 608 to increase or maximize the transmission of signals transmitted via the communication channel 616h. A-I-g In some aspects, the reflection relay configuration information may be used to configure the electromagnetic radiation reflection relay network node 608 to reduce or minimize the transmission of electromagnetic radiation via the communication channel 616h. A-I-g The signal strength of the signal transmitted. In some aspects, the reflection relay configuration information can be used to configure the electromagnetic radiation reflection relay network node 608 to reduce or minimize the CLI in the communication channel 606. For example, the CLI in the communication channel 610 can invalidate (e.g., cancel) all or part of the CLI in the communication channel 606. In this way, the various aspects described herein can promote the mitigation of CLI using a joint estimate of two channels based on one or more resources configured for CLI measurement associated with the electromagnetic radiation reflection relay network node, thereby positively affecting network performance.

[0101] As indicated above, Figure 6 are provided as examples. Other examples can be found in the Figure 6 Different than described.

[0102] Figure 7 is a diagram illustrating an example 700 associated with nonlinear modeling for channel estimation according to the present disclosure. As shown, network node 702, network node 704, network node 706, and network node 708 may communicate with each other. Network nodes 702, 704, 706, and / or 708 may be or resemble Figure 1 The network node 702 may be or may be similar to the network node 102 and / or the network node 104 depicted in FIG. Figure 6 The network node 614 depicted in FIG. The network node 704 may be a victim network node and may be or be similar to Figure 6 604 as depicted in FIG. 606 may be an attacker network node and may be or be similar to Figure 6 The network node 602 depicted in FIG. The network node 708 may be an electromagnetic radiation reflection relay network node and may be or be similar to Figure 6 The electromagnetic radiation depicted in FIG. 6 is reflected by a relay network node 608 .

[0103] As shown by reference numeral 710, first network node 702, second network node 704, third network node 706, and / or fourth network node 708 may perform an attacker network node identification process to identify an attacker network node. For example, in some aspects, network node 702 may receive information from one or more of network nodes 704, 706, and / or 708. Network node 702 may determine that network node 706 is an attacker network node based on the received information. In some aspects, network node 704 may determine that network node 702 is an attacker network node.

[0104] As indicated by reference numeral 712, the network node 702 may send CLI configuration information, and the network node 704 may receive the CLI configuration information. Similarly, as indicated by reference numeral 714, the network node 702 may send CLI configuration information, and the network node 706 may receive the CLI configuration information. In some aspects, the CLI configuration information sent to the network node 704 may be the same as the CLI configuration information sent to the network node 706. In some other aspects, the CLI configuration information sent to the network node 704 may be at least partially different from the CLI configuration information sent to the network node 706. For example, the CLI configuration information may configure the network node 704 with CLI measurement resources and / or CLI measurement parameters that may be used by the network node 704 to measure the CLI. The CLI configuration information may configure the network node 706 with precoding information, CLI reference signal resources (e.g., SRS resources), and / or CLI reference signal transmission parameters.

[0105] In some aspects, the CLI configuration information sent to the network node 704 may specify the network node 706 and the network node 708 (e.g., an electromagnetic radiation reflection relay network node). In some aspects, the CLI configuration information sent to the network node 704 and / or the network node 706 may include first information indicating a reference signal resource. In some aspects, the CLI configuration information sent to the network node 704 and / or 706 may include second information indicating a plurality of pre-coding vectors corresponding to a pre-coding matrix. The plurality of pre-coding vectors may include a first pre-coding vector and a second pre-coding vector. In some aspects, the plurality of pre-coding vectors may include at least one additional pre-coding vector, the at least one additional pre-coding vector being associated with at least one additional network node configured to provide at least one additional electromagnetic radiation reflection relay service. In some aspects, the network node 704 may include a memory including non-signaling information stored thereon, wherein the non-signaling information includes a first pre-coding vector and a second pre-coding vector.

[0106] As indicated by reference numeral 716, the network node 704 may receive a signal. In some aspects, the signal may include a reference signal, such as, for example, an SRS. In some aspects, the signal may include a first signal characteristic 718 associated with a first precoding vector corresponding to a first communication channel between the network node 704 and the network node 702. In some aspects, the first signal characteristic may be referred to as a first “aggressor reference signal” and may be precoded by first precoding information (e.g., a first precoding vector). For example, the first signal characteristic may include a first aggressor reference signal sent by the network node 704 and may be denoted as h A-V c 11 s, where h A-V is the communication channel between network node 704 and network node 702, c 11 is the channel h A-V , and s is the configured CLI resource (e.g., SRS resource). In some aspects, the network node 704 may receive at least one additional signal. The at least one additional signal may include at least one additional signal characteristic associated with the first communication channel. For example, the at least one additional signal characteristic may include a second aggressor reference signal sent by the network node 704 and may be represented as h A-V c 21 s, where h A-V is a first communication channel between network node 704 and network node 702, c 21 is the channel h A-VThe associated second precoding information (eg, precoding), and s is the configured CLI resource (eg, SRS resource) associated with the second aggressor reference signal.

[0107] The signal may also include a second signal characteristic 720 associated with a second precoding vector corresponding to a second communication channel between network node 704 and network node 706. The second signal characteristic may be referred to as a "first reflected reference signal" and may be precoded by third precoding information (e.g., a third precoding vector). For example, the first reflected reference signal may be represented as h A-I-V c 12 s, where h A-I-V is a second communication channel between the network node 704 and the network node 706, c 12 The at least one additional signal may include a fourth reflected reference signal sent from the network node 708 (eg, as a reflection of a transmission from the network node 702). The fourth reflected reference signal may use the fourth precoding information c 22 to pre-decode and can be obtained by h A-I-V c 22 In some aspects, the first aggressor reference signal and the first reflected reference signal may overlap in time (e.g., partially overlap in time or completely overlap in time), and the second aggressor reference signal and the second reflected reference signal may overlap in time (e.g., partially overlap in time or completely overlap in time).

[0108] Thus, a signal (which may be a first transmission (T1) of a plurality of transmissions received by the network node 704) may be represented as y T1 =HC T1 =h A-V c 11 s+h A-I-V c 12 s, where H is the communication channel associated with the signal, s is the configured CLI resource, and C T1 ={c 11 , c 12} is the pre-coding vector associated with the communication channel H at the first transmission T1. At time T2, the network node 704 may receive at least one additional signal y T2 =HC T2 =h A-V c 21 s+h A-I-V c 22 s, where the pre-decoding vector is defined as C T2 ={c 21 , c 22}.

[0109] As indicated by reference numeral 722, the network node 704 may generate channel estimation information. The channel estimation information may include first channel estimation information and second channel estimation information. The first channel estimation information may correspond to a first communication channel and may be based on a first precoding vector, and the second channel estimation information may correspond to a second communication channel and may be based on a second precoding vector associated with the second communication channel. For example, the channel estimation information may be based on a plurality of aggressor reference signals and a plurality of reflected reference signals. The first channel information may indicate one or more channel characteristics corresponding to the first channel, and the second channel information may indicate one or more channel characteristics corresponding to the second channel. For example, in summary, Y={y T1 ,y T2}, where Y = HCs, and where C = {C T1 , C T2} is a 2×2 matrix and may be known to the network node 704 as a configuration, and s is the configured CLI SRS resource. Since both C and s may be known to the network node 704, H may generally be estimated as H via any number of different matrices and / or algebraic mathematical operations. est For example, in some aspects, H est =Y*Inverse(Cs).

[0110] As shown by reference numeral 724, network node 704 may send channel estimation information, and network node 702 may receive the channel estimation information. In some aspects, the channel estimation information may include first channel estimation information and second channel estimation information. In some aspects, the channel estimation information may be based on CLI configuration information. In some aspects, the channel estimation may be configured to be reported as channel estimation information based on each victim network node. For example, network node 704 may be configured (e.g., by network node 702) to report channels from an indicated aggressor network node and an indicated electromagnetic radiation reflection relay network node.

[0111] In some aspects, for example, the first channel estimation information may include first original channel estimation information, and the second channel estimation information may include second original channel estimation information. The first original channel estimation information and the second original channel estimation information may be non-differential information and non-quantized information. In some aspects, the first channel estimation information may indicate a first channel estimation value associated with the first communication channel, and the second channel estimation information may be a differential value indicating the second channel estimation value. The differential value may be relative to the first channel estimation value. For example, in some aspects, the differential value may correspond to h A-V-est With h A-I-V-est In some aspects, the first channel estimation information may include first quantized channel estimation information, and the second channel estimation information may include second quantized channel estimation information. For example, the channel estimation information may include hA-V-est and h A-I-V-est , which may include a single corresponding value indicative of a corresponding channel estimate.

[0112] As shown by reference numeral 726, the network node 702 may determine the reflection relay configuration information. For example, the reflection relay configuration information may include one or more electromagnetic reflection parameters based on the channel estimation information. In some aspects, the one or more electromagnetic reflection parameters may include at least one of a phase shift coefficient or an amplitude coefficient. In some aspects, the one or more electromagnetic reflection parameters may include one or more electromagnetic reflection parameters that are determined to mitigate the CLI associated with at least one of the first communication channel or the second communication channel. For example, in some aspects, the network node 702 may determine one or more electromagnetic reflection parameters to increase the signal strength associated with the second communication channel. In some aspects, the network node 702 may determine one or more electromagnetic reflection parameters to reduce the signal strength associated with the second communication channel.

[0113] The network node 702 may send the reflection relay configuration information and the network node 708 may receive the reflection relay configuration information, as indicated by reference numeral 728. The reflection relay configuration information may indicate one or more electromagnetic reflection parameters based on the channel estimation information.

[0114] As indicated above, Figure 7 are provided as examples. Other examples can be found in the Figure 7 For example, in some aspects, the aspects can be applied to scenarios involving two or more electromagnetic radiation reflection relay network nodes. For example, the dimensions of the pre-decoding matrix C can be expanded so that the number of columns corresponds to the number of reference signal transmissions, and the number of rows scales with the number of electromagnetic radiation reflection relay network nodes.

[0115] Figure 8 is a diagram illustrating an example process 800 performed, for example, by a first network node in accordance with the present disclosure. The example process 800 is an example in which a first network node (eg, network node 704) performs operations associated with reporting a CLI associated with an electromagnetic radiation reflection relay service.

[0116] like Figure 8 As shown, in some aspects, process 800 may include receiving CLI configuration information (block 810). For example, a first network node (e.g., using Fig.11 The communications manager 1108 and / or receiving component 1102 depicted in FIG. 10A may receive CLI configuration information as described above.
