[0001] Cross - Reference to Related Applications

[0002] This patent application claims priority to PCT Patent Application No. PCT / CN2020 / 089108, titled "RADIO RESOURCE CONFIGURATION FOR SELF - INTERFERENCE MEASUREMENT", filed on May 8, 2020, and assigned to the assignee of the present application. The disclosure of the prior application is considered to be a part of this patent application and is incorporated herein by reference. Technical Field

[0003] Aspects of the present disclosure generally relate to wireless communication and relate to techniques and apparatuses for radio resource configuration for self - interference measurement. Background Art

[0004] Wireless communication systems have been widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasting. A typical wireless communication system may employ a multiple access technology 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 an enhanced set for the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP).

[0005] A wireless network may include multiple Base Stations (BSs) that can support communication of multiple User Equipments (UEs). The UE can communicate with the BS via the downlink and the uplink. The "downlink" (or "forward link") refers to the communication link from the BS to the UE, while the "uplink" (or "reverse link") refers to the communication link from the UE to the BS. As will be described in more detail herein, the BS may be referred to as Node B, gNB, Access Point (AP), Radio Head, Transmission and Reception Point (TRP), New Radio (NR) BS, 5G Node B, etc.

[0006] The above various multiple access technologies have been adopted in telecommunication standards to provide a common protocol that enables different user devices to communicate at the urban, national, regional, or even global level. New Radio (NR), which can also be referred to as 5G, is an enhanced set for the LTE mobile standard promulgated by 3GPP. NR is designed to better support mobile broadband Internet access by improving spectral efficiency, reducing costs, enhancing services, leveraging new spectrums, and better integrating with other open standards. These open standards use Orthogonal Frequency Division Multiplexing (OFDM) with Cyclic Prefix (CP) (CP-OFDM) on the Downlink (DL), and CP-OFDM and / or Single Carrier - Frequency Division Multiplexing (SC - FDM) (e.g., also referred to as Discrete Fourier Transform Spread OFDM (DFT - s - OFDM)) on the Uplink (UL), and support beamforming, Multiple - Input Multiple - Output (MIMO) antenna technology, and carrier aggregation. With the continuous growth of the demand for mobile broadband access, further improvements to LTE, NR, and other radio access technologies remain useful. SUMMARY OF THE INVENTION

[0028] Aspects of the present disclosure will be described more fully hereinafter with reference to the accompanying drawings. However, the present disclosure may be embodied in many different forms and should not be construed as limited to any specific 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 the present disclosure to those skilled in the art. Based on the teachings herein, those skilled in the art should understand that the scope of the present disclosure is intended to cover any aspect of the disclosure disclosed herein, whether implemented independently or in combination with any other aspect of the present disclosure. For example, any number of the aspects set forth herein may be used to implement an apparatus or practice a method. In addition, the scope of the present disclosure is intended to cover such an apparatus or method practiced using other structures, functions, or combinations of structures and functions in addition to or different from the aspects of the present disclosure set forth herein. It should be understood that any aspect of the present disclosure disclosed herein may be embodied by one or more elements of a claim.

[0029] Certain aspects of a telecommunications system will now be presented with reference to various apparatuses and techniques. These apparatuses and techniques will be described in the following detailed description and illustrated in the drawings by various boxes, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements may be implemented using hardware, software, or a combination thereof. Whether the elements are implemented in hardware or software form depends on the particular application and the design constraints imposed on the overall system.

[0030] It should be noted that although terms commonly associated with 5G or NR radio access technology (RAT) may be used herein to describe aspects, aspects of the present disclosure may be applied to other RATs, such as 3G RAT, 4G RAT, and / or post-5G RATs (e.g., 6G RAT).

[0031] Figure 1FIG. is a diagram illustrating an example of a wireless network 100 in accordance with the present disclosure. The wireless network 100 may be or may include elements of a 5G (NR) network and / or an LTE network, etc. The wireless network 100 may include a plurality of base stations 110 (shown as BS110a, 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, transmit receive point (TRP), etc. Each BS may provide communication coverage for a specific geographic area. In 3GPP, depending on the context in which the term is used, the term "cell" may refer to the coverage area of a BS and / or the BS subsystem serving that coverage area.

[0032] The BS may provide communication coverage for macro cells, picocells, femtocells, and / or other types of cells. A macro cell may cover a relatively large geographic area (e.g., with a radius of several kilometers) and may allow unrestricted access by UEs having a service subscription. A picocell may cover a relatively small geographic area and may allow unrestricted access by UEs having a service subscription. A femtocell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by UEs associated with the femtocell (e.g., UEs in a closed subscriber group (CSG)). The BS of a macro cell may be referred to as a macro BS. The BS of a picocell may be referred to as a pico BS. The BS of a femtocell may be referred to as a femto BS or a home BS. In Figure 1 the example shown, BS 110a may be a macro BS of macro cell 102a, BS 110b may be a pico BS of picocell 102b, and BS 110c may be a femto BS of femtocell 102c. A BS may support one or more (e.g., three) cells. Herein, the terms "eNB", "base station", "NR BS", "gNB", "TRP", "AP", "Node B", "5G NB", and "cell" may be used interchangeably.

[0033] In some aspects, the cell is not necessarily fixed, and the geographic area of the cell may move according to the location of the mobile BS. In some aspects, the BSs may be interconnected with each other and / or with one or more other BSs or network nodes (not shown) in the wireless network 100 using any suitable transport network via various types of backhaul interfaces such as direct physical connections or virtual networks.

[0034] The wireless network 100 may also include relay stations. A relay station is an entity that can receive a transmission of data from an upstream station (e.g., a BS or a UE) and send a transmission of the data to a downstream station (e.g., a UE or a BS). A relay station may also be a UE that can relay transmissions for other UEs. InFigure 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. The relay BS can also be referred to as a relay station, relay base station, relay, etc.

[0035] Wireless network 100 can be a heterogeneous network including different types of BSs (such as macro BSs, pico BSs, femto BSs, relay BSs, etc.). These different types of BSs can have different transmission power levels, different coverage areas, and different impacts on interference in wireless network 100. For example, a macro BS can have a high transmission power level (e.g., 5 to 40 watts), while pico BSs, femto BSs, and relay BSs can have lower transmission power levels (e.g., 0.1 to 2 watts).

[0036] Network controller 130 can be coupled to a set of BSs and can provide coordination and control for these BSs. Network controller 130 can communicate with the BSs via a backhaul. The BSs can also communicate with each other directly or indirectly via a wireless or wired backhaul.

[0037] UEs 120 (e.g., 120a, 120b, 120c) can be dispersed throughout wireless network 100, and each UE can be fixed or mobile. The UE can also be referred to as an access terminal, terminal, mobile station, subscriber unit, station, etc. The UE can also be a mobile phone (smartphone), personal digital assistant (PDA), wireless modem, wireless communication device, handheld device, laptop computer, cordless phone, wireless local loop (WLL) station, tablet, camera, gaming device, netbook, smartbook, ultrabook, medical device or instrument, 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, etc.), vehicle component or sensor, smart meter / sensor, industrial manufacturing instrument, global positioning system device, or any other suitable device configured to communicate via a wireless or wired medium.

[0038] Some UEs can be considered as 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, meters, monitors, and / or location tags, which can communicate with a base station, other devices (such as remote devices), or some other entity. A wireless node can provide, for example, a connection to or for a network (such as a wide area network such as the Internet or a cellular network) via a wired or wireless communication link. Some UEs can be considered as Internet of Things (IoT) devices, and / or can be implemented as NarrowBand IoT (NB-IoT) devices. Some UEs can be considered as Customer Premises Equipment (CPE). UE 120 can be included within an enclosure that houses components of UE 120, such as a processor component and / or a memory component. In some aspects, the processor component and the memory component can be coupled together. For example, the processor component (e.g., one or more processors) and the memory component (e.g., a memory) can be operably coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0039] Generally, 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. The RAT can also be referred to as a radio technology, an air interface, etc. The frequency can also be referred to as a carrier, a channel, etc. Each frequency can support a single RAT within a given geographical area to avoid interference between wireless networks of different RATs. In some cases, an NR or 5G RAT network can be deployed.

[0040] In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) can communicate directly using one or more sidelink channels (e.g., without using the base station 110 as an intermediary for communicating with each other). For example, UE120 can communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which can include vehicle-to-vehicle (V2V) protocols or vehicle-to-infrastructure (V2I) protocols), and / or a mesh network. In such cases, UE120 can perform scheduling operations, resource selection operations, and / or other operations performed by the base station 110 described elsewhere herein.

[0041] Devices of the wireless network 100 can communicate using the electromagnetic spectrum, which can be subdivided into various categories, frequency bands, channels, etc. based on frequency or wavelength. For example, devices of the wireless network 100 can communicate using an operating band having a first frequency range (FR1) that can span from 410 MHz to 7.125 GHz, and / or can communicate using an operating band having a second frequency range (FR2) that can span from 24.25 GHz to 52.6 GHz. The frequencies between FR1 and FR2 are sometimes referred to as mid-band frequencies. Although part of FR1 is above 6 GHz, FR1 is generally referred to as the "sub-6 GHz" band. Similarly, FR2 is also often referred to as the "millimeter wave" band, although it is different from the extremely high frequency (EHF) band (30 GHz - 300 GHz) defined as the "millimeter wave" band by the International Telecommunication Union (ITU). Thus, unless otherwise specified, it should be understood that if used herein, terms such as "sub-6 GHz" can broadly represent frequencies below 6 GHz, frequencies within FR1, and / or mid-band frequencies (e.g., above 7.125 GHz). Similarly, unless otherwise specified, it should be understood that if used herein, terms such as "millimeter wave" can broadly represent frequencies within the EHF band, frequencies within FR2, and / or mid-band frequencies (e.g., below 24.25 GHz). It is contemplated that the frequencies included in FR1 and FR2 can be modified, and the techniques described herein apply to those modified frequency ranges.

[0042] As described above, Figure 1 is provided as an example. Other examples may be different from Figure 1 that described with reference to

[0043] Figure 2 FIG. 200 is a diagram illustrating an example 200 of communication between a base station 110 and a UE 120 in the 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, where generally, T≥1 and R≥1.

[0044] At base station 110, transmit processor 220 may receive data for one or more UEs from data source 212, select one or more modulation and coding schemes (MCSs) for each UE at least in part based on channel quality indicators (CQIs) received from the UEs, process (e.g., encode and modulate) the data for each UE at least in part based on the MCSs selected for the UEs, and provide data symbols for all UEs. Transmit processor 220 may also 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. Transmit processor 220 may also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRSs) or demodulation reference signals (DMRSs)) and synchronization signals (e.g., primary synchronization signals (PSSs) or secondary synchronization signals (SSSs)). If applicable, transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on the data symbols, control symbols, overhead symbols, and / or reference symbols, and may provide T output symbol streams to T modulators (MODs) 232a through 232t. Each modulator 232 may process its respective output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modulator 232 may also process (e.g., convert to analog, amplify, filter, and upconvert) the output sample stream to obtain a downlink signal. The T downlink signals from modulators 232a through 232t may be transmitted via T antennas 234a through 234t, respectively.

[0045] At the UE 120, antennas 252a through 252r may receive downlink signals from the base station 110 and / or other base stations and may respectively provide the received signals to demodulators (DEMOD) 254a through 254r. Each demodulator 254 may condition (e.g., filter, amplify, down-convert, and digitize) the received signal to obtain input samples. Each demodulator 254 may also process the input samples (e.g., for OFDM) to obtain received symbols. The MIMO detector 256 may obtain received symbols from all R demodulators 254a through 254r, perform MIMO detection on the received symbols if applicable, and provide the detected symbols. The receive processor 258 may process (e.g., demodulate and decode) the detected symbols, provide the decoded data for the UE 120 to the data sink 260, and provide the decoded control information and system information to the controller / processor 280. The term "controller / processor" may refer to one or more controllers, one or more processors, or a combination thereof. The channel processor may determine reference signal received power (RSRP) parameters, received signal strength indicator (RSSI) parameters, reference signal received quality (RSRQ) parameters, and / or channel quality indicator (CQI) parameters, etc. In some aspects, one or more components of the UE 120 may be included in a housing.

[0046] The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292. The network controller 130 may include, for example, one or more devices in a core network. The network controller 130 may communicate with the base station 110 via the communication unit 294.

[0047] Antennas (e.g., antennas 234a through 234t and / or antennas 252a through 252r) may include one or more antenna panels, antenna groups, collections of antenna elements, and / or antenna arrays, etc., or may be included in one or more antenna panels, antenna groups, collections of antenna elements, and / or antenna arrays, etc. The antenna panel, antenna group, collection of antenna elements, and / or antenna array may include one or more antenna elements. The antenna panel, antenna group, collection of antenna elements, and / or antenna array may include a collection of coplanar antenna elements and / or a collection of non-coplanar antenna elements. The antenna panel, antenna group, collection of antenna elements, and / or antenna array may include antenna elements within a single housing and / or antenna elements within multiple housings. The antenna panel, antenna group, collection of antenna elements, and / or antenna array may include one or more antenna elements coupled to one or more transmit and / or receive components (such as Figure 2 one or more components) of

[0048] On the uplink, at the UE 120, the transmit processor 264 can receive and process data from the data source 262 and control information from the 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. If applicable, the symbols from the transmit processor 264 can be precoded by the TX MIMO processor 266, further processed by the modulators 254a through 254r (e.g., for DFT-s-FDM or CP-OFDM), and transmitted to the base station 110. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 254) of the UE 120 can be included in the modem of the UE 120. In some aspects, the UE 120 includes a transceiver. The transceiver can include any combination of the antenna 252, the modulator and / or demodulator 254, the MIMO detector 256, the receive processor 258, the transmit processor 264, and / or the TX MIMO processor 266. The processor (e.g., the controller / processor 280) and the memory 282 can use the transceiver to perform aspects of any of the methods described herein, e.g., as described with reference to Figures 3 to 9 as described.

[0049] At the base station 110, the uplink signals from the UE 120 and other UEs can be received by the antenna 234, processed by the demodulator 232, detected by the MIMO detector 236 if applicable, and further processed by the receive processor 238 to obtain the decoded data and control information transmitted by the UE 120. The receive processor 238 can provide the decoded data to the data sink 239 and the decoded control information to the controller / processor 240. The base station 110 can include a communication unit 244 and communicate with the network controller 130 via the communication unit 244. The base station 110 can include a scheduler 246 for scheduling the UE 120 for downlink and / or uplink communication. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 232) of the base station 110 can be included in the modem of the base station 110. In some aspects, the base station 110 includes a transceiver. The transceiver can include any combination of the antenna 234, the modulator and / or demodulator 232, the MIMO detector 236, the receive processor 238, the transmit processor 220, and / or the TX MIMO processor 230. The processor (e.g., the controller / processor 240) and the memory 242 can use the transceiver to perform aspects of any of the methods described herein, e.g., as described with reference to Figures 3 to 9 as described.

[0050] The controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2Any other component of may perform one or more techniques associated with the configuration of self-interference, as described in more detail elsewhere herein. For example, the controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component of may perform or direct, for example Figure 8 Process 800 of Figure 9 Process 900 of and / or the operation of other processes as described herein. The memories 242 and 282 may store data and program code for the base station 110 and the UE 120, respectively. In some aspects, the memory 242 and / or the memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, when run by one or more processors of the base station 110 and / or the UE 120 (e.g., directly executed or after compilation, conversion, and / or interpretation), the one or more instructions may cause the one or more processors, the UE 120, and / or the base station 110 to perform or direct, for example Figure 8 Process 800 of Figure 9 Process 900 of and / or the operation of other processes as described herein. In some aspects, running the instructions may include running instructions, conversion instructions, compilation instructions, and / or interpretation instructions, etc.

[0051] In some aspects, the UE 120 may include components for receiving configuration information indicating a resource set for self-interference measurement associated with the full-duplex communication mode, components for sending a signal according to the configuration information, components for determining a self-interference measurement based at least in part on the signal and the resource set, components for sending information indicating the self-interference measurement, etc. In some aspects, these components may include one or more components of the UE 120 described in connection with Figure 2 such as the controller / processor 280, the transmit processor 264, the TX MIMO processor 266, the MOD 254, the antenna 252, the DEMOD 254, the MIMO detector 256, the receive processor 258, etc.

[0053] Although Figure 2 the boxes in Figure 2 are shown as different components, the functions described above with reference to each box can be implemented in a single hardware, software, or combined component, or in various combinations of components. For example, the functions described with reference to the transmit processor 264, the receive processor 258, and / or the TX MIMO processor 266 can be performed by or under the control of the controller / processor 280.

[0054] As described above, Figure 2 is provided as an example. Other examples may be different from what is described with reference to Figure 2 Figure 2 .

[0055] Figure 3 FIG. 300 is a diagram illustrating an example of a radio access network in accordance with various aspects of the present disclosure.

[0056] As shown by reference numeral 305, a conventional (e.g., 3G, 4G, LTE, etc.) radio access network may include a plurality of base stations 310 (e.g., access nodes (AN)), where each base station 310 communicates with the core network via a wired backhaul link 315 (such as a fiber optic connection). The base station 310 may communicate with the UE 320 via an access link 325, which may be a wireless link. In some aspects, Figure 3 the base station 310 shown may be Figure 1 the base station 110 shown. In some aspects, Figure 3 the UE 320 shown may be Figure 1 the UE 120 shown.

[0057] As shown by reference numeral 330, a radio access network may include a wireless backhaul network, which is sometimes referred to as an integrated access and backhaul (IAB) network. In an IAB network, at least one base station is an anchor base station 335, which communicates with the core network via a wired backhaul link 340 (such as a fiber optic connection). The anchor base station 335 may also be referred to as an IAB donor (or IAB-donor). The IAB network may include one or more non-anchor base stations 345, which are sometimes referred to as relay base stations or IAB nodes (or IAB-nodes). The non-anchor base station 345 may communicate directly or indirectly with the anchor base station 335 via one or more backhaul links 350 (e.g., via one or more non-anchor base stations 345) to form a backhaul path to the core network for carrying backhaul traffic. The backhaul link 350 may be a wireless link. The anchor base station 335 and / or the non-anchor base station 345 may communicate with one or more UEs 355 via an access link 360, which may be a wireless link for carrying access traffic. In some aspects, Figure 3 the anchor base station 335 and / or the non-anchor base station 345 shown may beFigure 1 Base station 110 as shown. In some aspects, Figure 3 UE 355 as shown can be Figure 1 UE 120 as shown.

[0058] As shown by reference numeral 365, in some aspects, a radio access network including an IAB network can utilize millimeter wave technology and / or directional communication (e.g., beamforming, etc.) for communication between a base station and / or a UE (e.g., between two base stations, between two UEs, and / or between a base station and a UE). For example, the wireless backhaul link 370 between base stations can use millimeter wave signals to carry information and / or can be directed to a target base station using beamforming, etc. Similarly, the wireless access link 375 between a UE and a base station can use millimeter wave signals and / or can be directed to a target radio node (e.g., a UE and / or a base station). In this way, interference between links can be reduced.

[0059] Is shown as an example Figure 3 The configurations of the base station and the UE in Figure 3 One or more base stations as shown in can be replaced by one or more UEs that communicate via a UE-to-UE access network (e.g., a peer-to-peer network, a device-to-device network, etc.). In this case, a UE that communicates directly with a base station (e.g., an anchor base station or a non-anchor base station) can be referred to as an anchor node.

[0060] As described above, Figure 3 Is provided as an example. Other examples may be different from the content described with reference to Figure 3 What is described.

[0061] Figure 4 Is a diagram showing an example 400 of an IAB network architecture according to various aspects of the present disclosure.

[0062] As Figure 4As shown, the IAB network may include an IAB host 405 (shown as IAB-Host) connected to the core network via a wired connection (shown as wired backhaul). For example, the Ng interface of the IAB host 405 may terminate at the core network. Additionally or alternatively, the IAB host 405 may be connected to one or more devices of the core network that provide core access and mobility management functions (e.g., AMF). In some aspects, the IAB host 405 may include a base station 110 (such as an anchor base station), as described above in connection with 3. As shown, the IAB host 405 may include a central unit (CU), which may perform access node controller (ANC) functions, AMF functions, etc. In some aspects, the CU may be referred to as a central control node (CCN). The CU may configure the distributed unit (DU) of the IAB host 405 and / or may configure one or more IAB nodes 410 (e.g., the MT and / or DU of the IAB node 410) connected to the core network via the IAB host 405. Thus, the CU of the IAB host 405 may control and / or configure the entire IAB network connected to the core network via the IAB host 405 (such as by using control messages and / or configuration messages (e.g., radio resource control (RRC) configuration messages, F1 application protocol (F1AP) messages, etc.)).

[0063] As Figure 4 As shown, the IAB network may include IAB nodes 410 (shown as IAB-Node 1, IAB-Node 2, and IAB-Node 3) connected to the core network via the IAB host 405. As shown, the IAB node 410 may include a mobile termination (MT) function (sometimes also referred to as UE function (UEF)) and may include a DU function (sometimes also referred to as access node function (ANF)). The MT function of the IAB node 410 (e.g., a child node) may be controlled and / or scheduled by another IAB node 410 (e.g., the parent node of the child node) and / or the IAB host 405. The DU function of the IAB node 410 (e.g., a parent node) may control and / or schedule other IAB nodes 410 (e.g., the child nodes of the parent node) and / or the UE 120. Thus, the DU may be referred to as a scheduling node or scheduling component, while the MT may be referred to as a scheduled node or scheduled component. In some aspects, the IAB host 405 may include a DU function but not an MT function. That is, the IAB host 405 may configure, control, and / or schedule the communication of the IAB nodes 410 and / or the UE 120. The UE 120 may only include an MT function and not a DU function. That is, the communication of the UE 120 may be controlled and / or scheduled by the IAB host 405 and / or the IAB nodes 410 (e.g., the parent node of the UE 120).

[0064] When the first node controls and / or schedules the communication of the second node (e.g., when the first node provides the DU function for the MT function of the second node), 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 DU function of the parent node can control and / or schedule the communication of the child nodes of the parent node. The parent node can be the IAB host 405 or the IAB node 410, and the child node can be the IAB node 410 or the UE 120. The communication of the MT function of the child node can be controlled and / or scheduled by the parent node of the child node.

[0065] As Figure 4 As further shown, the link between the UE 120 (e.g., which only has the MT function and does not have the DU function) and the IAB host 405, or the link between the UE 120 and the IAB node 410 can be referred to as the access link 415. The access link 415 can be a wireless access link that provides wireless access to the core network to the UE 120 via the IAB host 405 and optionally via one or more IAB nodes 410. Therefore, Figure 4 the network shown can be referred to as a multi-hop network or a wireless multi-hop network.

[0066] As Figure 4 As further shown, the link between the IAB host 405 and the IAB node 410 or between two IAB nodes 410 can be referred to as the backhaul link 420. The backhaul link 420 can be a wireless backhaul link that provides wireless access to the core network to the IAB node 410 via the IAB host 405 and optionally via one or more other IAB nodes 410. In the IAB network, network resources for wireless communication (e.g., time resources, frequency resources, spatial resources, etc.) can be shared between the access link 415 and the backhaul link 420. In some aspects, the backhaul link 420 can be a primary backhaul link or a secondary backhaul link (e.g., a standby backhaul link). In some aspects, if the primary backhaul link fails, becomes congested, becomes overloaded, etc., the secondary backhaul link can be used. For example, if the primary backhaul link between IAB-node 2 and IAB-node 1 fails, the standby link 425 between IAB-node 2 and IAB-node 3 can be used for backhaul communication. As used herein, the IAB host 405 or the IAB node 410 can be referred to as a node or a wireless node.

[0067] In some cases, the IAB node 410 may be subject to self-interference due to full-duplex operation. In such cases, the IAB node 410 may perform self-interference measurements to detect and / or mitigate self-interference. However, if other UEs or nodes near the IAB node 410 are performing data reception on the same time-frequency resources as the time-frequency resources used for self-interference measurements, the signals used for self-interference measurements may interfere with other UEs or nodes. Some of the techniques and apparatuses described herein provide scheduling and / or configuration of rules for the transmission of signals for self-interference management in order to reduce, eliminate, or avoid interference to nearby nodes and / or UEs.

[0068] As described above, Figure 4 is provided as an example. Other examples may be different from what is described with reference to Figure 4 what is described.

[0069] Figure 5 is a diagram of an example 500 showing communication links between IAB nodes and / or UEs of a network. As shown, example 500 includes a parent node 510, an IAB node 520, a child node 530, and a UE 120. Each of the parent node 510, the IAB node 520, and the child node 530 may be an IAB node (e.g., BS110, relay BS 110, wireless node, etc.). In some aspects, the parent node 510 may be an IAB host. The parent node 510 is the parent of the IAB node 520, and the child node 530 is the child of the IAB node 520. The child node 530 may be referred to as the grandchild of the parent node 510, and the parent node 510 may be referred to as the grandfather of the child node 530. The network may be associated with a CU (not shown in Figure 5 ).

[0070] The nodes 510, 520, 530, and UE 120 are associated with communication links with each other. Reference numerals 540, 550, and 560 illustrate downlink (DL) communication links. The DL parent backhaul (BH) link 540 provides a DL backhaul (i.e., a backhaul link) from the parent node 510 to the IAB node 520. The DL child BH link 550 provides a DL backhaul from the IAB node 520 to the child node 530. The DL access link 560 provides a DL access link from the IAB node 520 to the UE 120. Reference numerals 570, 580, and 590 illustrate uplink (UL) communication links. The UL parent backhaul (BH) link 570 provides a UL backhaul from the IAB node 520 to the parent node 510. The UL child BH link 580 provides a UL backhaul from the child node 530 to the IAB node 520. The UL access link 590 provides a UL access link from the UE 120 to the IAB node 520.

[0071] In some cases, the IAB node 520 may be subject to self-interference. For example, if the IAB node 520 is associated with a full-duplex communication mode, the signals transmitted in any transmit link may cause self-interference to the signals received in any receive link. As an example, the signals transmitted in the UL parent BH link 570 may cause self-interference to the signals received simultaneously in the UL child BH link 580 or the UL access link 590. When the interference intensity is large enough (e.g., greater than the thermal noise power level), the interference may degrade the reception performance of the corresponding channel or signal. Some of the techniques and apparatuses described herein provide configurations for self-interference measurement for one or more nodes, such as the IAB node 520 or the UE 120.

[0072] As described above, Figure 5 is provided as an example. Other examples may be different from those Figure 5 described with reference to

[0073] Figure 6 FIG. 600 is a diagram illustrating an example of self-interference in accordance with various aspects of the present disclosure. As shown, example 600 includes a BS 110 and a UE 120. The BS 110 is associated with a UL antenna set and a DL antenna set. In some aspects, the UL antenna set may include an antenna group, an antenna panel, an antenna array, an antenna sub-array, a TRP, etc. In some aspects, the DL antenna set may include an antenna group, an antenna panel, an antenna array, an antenna sub-array, a TRP, etc. In some aspects, the UL antenna set may be remote from the DL antenna set to reduce inter-talk interference between the UL antenna set and the DL antenna set. In some aspects, if the inter-antenna interference can be sufficiently mitigated, the UL antenna set may be located near the DL antenna set or may be integrated with the DL antenna set into a single antenna set.

[0074] The UE 120 is capable of transmitting signals (shown as UL data transfer) and receiving signals (shown as DL data transfer) on the same time-frequency radio resource. The simultaneous transmission and reception of signals on the same time-frequency resource is referred to herein as full-duplex communication. Full-duplex communication may be most efficient when the self-interference caused by the transmitted signals to the received signals (as indicated by reference numeral 610) can be mitigated such that both the DL data transfer and the UL data transfer are effective.

[0075] A full-duplex UE may not always operate in the full-duplex communication mode. For example, UE 120 can selectively operate in the full-duplex mode or the non-full-duplex mode based at least in part on factors such as whether the full-duplex mode can achieve a higher data rate than the non-full-duplex mode. Due to differences in product design and hardware / software implementation, the ability of some full-duplex UEs to mitigate self-interference may vary. The ability of a UE to mitigate self-interference can be fixed or can vary with the UE's transmit power, transmission bandwidth, transmission beamforming (precoding) weights, or other factors.

[0076] In some aspects, UE 120 can be configured with one or more channel state information interference measurement (CSI-IM) resource set configurations, as indicated by the higher layer parameter CSI-IM-ResourceSet. Each CSI-IM resource set can include K ≥ 1 CSI-IM resources. For a CSI-IM resource, parameters of "CSI-IM resource pattern", "period and offset", and "frequency band" can be configured. The CSI-IM resource pattern can indicate the frequency-domain and time-domain positions of resource elements in one occasion of the CSI-IM resource. In many cases, the serving gNB (e.g., BS 110) may not send data signals or reference signals on the CSI-IM resources, so that UE 120 can measure inter-cell interference on these resources and send a CSI report to the serving gNB. The gNB can configure periodic, semi-persistent, or aperiodic CSI-IM resources for UE120 corresponding to periodic, semi-persistent, or aperiodic CSI reports, respectively.

[0077] As described above, Figure 6 is provided as an example. Other examples may be different from the content described with reference to Figure 6 what is described.

[0078] The next generation of wireless networks (e.g., 5G / NR, etc.) is expected to provide ultra-high data rates and support a wide range of application scenarios. Wireless full-duplex (sometimes abbreviated as FD) communication can theoretically double the link capacity. In the wireless full-duplex communication mode, radio network nodes can transmit and receive simultaneously on the same frequency band and in the same time slot. This is in contrast to traditional half-duplex operation, where transmission and reception are different in time or frequency.

[0079] A full-duplex network node, such as a base station in a cellular network or an IAB node in an IAB network, can communicate with two half-duplex terminals using the same radio resources simultaneously in the uplink (UL) and the downlink (DL). Another typical wireless full-duplex application scenario is that a relay node can communicate with an anchor node and a mobile terminal simultaneously in a one-hop scenario or with two relay nodes simultaneously in a multi-hop scenario. It is expected that full duplex can significantly increase the system throughput of various applications in a wireless communication network by doubling the capacity of each single link and also reduce the transmission latency of time-critical services.

[0080] In some cases, a UE (referred to as an FD-capable UE) can have the ability to transmit and receive simultaneously using the same time-frequency radio resources. This can be referred to as operating in the self-FD mode or in the FD communication mode. Thus, the aggregated DL and UL throughput of a single UE can be greatly increased, which can be particularly beneficial when both DL and UL traffic are high for a single user.

[0081] Full-duplex communication can involve self-interference cancellation for in-band full-duplex transmission. Some full-duplex radio designs can suppress this kind of self-interference (e.g., uplink to downlink or downlink to uplink) to a certain extent by combining techniques such as beamforming, analog cancellation, digital cancellation, and antenna cancellation.

[0082] To measure self-interference, a full-duplex UE or node can transmit a signal while measuring the downlink channel quality by receiving a reference signal (e.g., a channel state information reference signal (CSI-RS)). The full-duplex UE can transmit a signal to simulate the self-interference of an uplink signal (e.g., a physical uplink shared channel (PUSCH), a sounding reference signal (SRS), a physical random access channel (PRACH), etc.) on the downlink signal. However, if other UEs or nodes near the UE or node are performing data reception on the same time-frequency resource, this signal may interfere with them. For example, if a UE in the same cell is receiving a downlink signal (such as a physical downlink shared channel (PDSCH) or CSI-RS) or if a BS in an adjacent cell is receiving an uplink signal (such as a PUSCH or SRS), these nodes may be interfered with by the signal transmitted by the full-duplex UE or node.

[0083] Some of the techniques and apparatuses described herein provide a configuration of a radio resource set (e.g., time-frequency resources) for a full-duplex UE or node for self-interference measurement. "Self-interference measurement" refers to determining a measurement that indicates interference caused by a transmit beam of a UE to a receive beam of the UE. "Self-interference measurement" may also refer to a measurement value determined by performing a self-interference measurement. A self-interference measurement may be performed by transmitting a signal on a first (transmit) beam and determining a level of interference associated with transmitting a signal using a second (receive) beam. A self-interference measurement may be performed for a single transmit beam and a single receive beam, multiple transmit beams and a single receive beam, or multiple transmit beams and multiple receive beams. For example, the configuration of radio resources may involve the configuration of a maximum transmit power parameter, a set of allowed (or disallowed) beamforming directions, a transmission sequence, etc. A full-duplex UE or node may measure self-interference intensity at least in part based on these configurations. For example, a UE may transmit a signal on the configured time-frequency resources with the configured power and / or beamforming direction and may measure self-interference accordingly. A UE may report a self-interference intensity value or a CSI value calculated at least in part based on the self-interference intensity to a base station. Thus, as part of the self-interference measurement process, the base station may configure power levels, beamforming directions, resources, and / or signal sequences that mitigate or prevent interference from the full-duplex UE or node to another UE or node. Mitigating or preventing such interference improves the communication efficiency of other UEs or nodes, thereby improving network performance and saving computational and communication resources.

[0084] Figure 7 FIG. Figure 7 is a diagram illustrating an example 700 of resources configured for self-interference measurement in accordance with various aspects of the present disclosure. As shown, example 700 includes UE 120 and BS 110. In example 700, UE 120 may be a full-duplex UE, which means that UE 120 operates in a full-duplex communication mode. The operations described in example 700 may also be applied to an IAB node. In this case, UE 120 in example 700 may represent an IAB node, and BS 110 may represent an IAB host (e.g., the CU / CCN of the IAB host), a parent node of the IAB node, etc.

[0085] As shown by reference numeral 710, BS 110 may send configuration information to UE 120. The configuration information may be provided using downlink control information (DCI) signaling, media access control (MAC) signaling (e.g., MAC control element), radio resource control (RRC) signaling, etc. In some aspects, the configuration information may be provided in a CSI report configuration message. As shown, the configuration information may include one or more of information indicating a resource set for self-interference measurement associated with a full-duplex communication mode, information indicating a transmission power parameter of a signal, information indicating a beamforming direction parameter of a signal, or information indicating a transmission sequence of a signal. The signal may include any signal for self-interference measurement, as described in more detail elsewhere herein.

[0086] In some aspects, the configuration information may indicate the transmission sequence of the signal. For example, if the configuration information does not indicate a transmission sequence, UE 120 may send any arbitrary sequence (such as a sequence that may be used for CSI-IM resources). If the configuration information indicates a transmission sequence, UE 120 may use the indicated transmission sequence for the signal. For example, the transmission sequence may include NZP-CSI-RS for interference measurement, etc.

[0087] In some aspects, the configuration information may indicate a resource set for self-interference measurement. For example, if self-interference measurement is performed while UE 120 is receiving NZP-CSI-RS, the time-frequency position of the self-interference measurement may coincide with the resource elements (REs) of the NZP-CSI-RS resource associated with the NZP-CSI-RS. In such a case, in some aspects, BS110 may explicitly configure the RE position (e.g., symbol index, subcarrier index, etc.) for self-interference measurement to match the NZP-CSI-RS resource. If the NZP-CSI-RS resource is a periodic resource, BS 110 may also configure the period and / or offset that matches the periodic resource. In some aspects, BS 110 may implicitly configure the resource position of the self-interference measurement that matches the associated NZP-CSI-RS resource. For example, BS 110 may provide an indication that the NZP-CSI-RS resource will be used as a self-interference management resource. Explicit signaling may provide increased flexibility, while implicit signaling may reduce overhead.

[0088] In some aspects, the configuration information may indicate the transmission power parameter of the signal. For example, in order to reduce the interference to another UE or node (e.g., a base station or an IAB node) that receives the signal for self-interference measurement on the same time-frequency resources as the self-interference measurement, BS 110 may indicate the transmission power parameter to UE 120. In some aspects, the transmission power parameter may indicate the maximum transmission power of the signal. In this case, UE 120 may not be permitted to transmit the signal at a transmission power higher than the threshold defined by the maximum transmission power.

[0089] In some aspects, the transmission power parameter may indicate the allowed received power level. The allowed received power level may indicate a threshold of the expected received power (e.g., per resource block (RB), etc.) at the receiver of the signal. UE 120 may not be permitted to transmit the signal at a transmission power that causes the signal to exceed the allowed received power level at the receiver. In this case, UE 120 may determine the path loss value of the downlink transmission from BS 110, and may use the path loss value and the allowed received power level to determine the transmission power of the signal. In some aspects, the allowed received power level may be equal to or at least partially based on the expected received power level per RB of the PUSCH, physical uplink control channel, SRS, etc. In some aspects, the configuration information may indicate a combination of the transmission power parameter (e.g., the maximum transmission power) and the allowed received power level. For example, UE 120 may be permitted to transmit a signal at a power level lower than the maximum transmission power and expected to be received at a power level that meets the allowed received power level. Thus, the interference at other nodes or UEs is reduced compared to transmitting the signal at full power or without reduced power.

[0090] In some aspects, the configuration information may indicate the beamforming direction parameter of the signal. For example, BS 110 may configure the beamforming direction parameter to reduce the interference at the UE or node in the spatial direction. In some aspects, BS 110 may indicate the set of allowed beamforming directions. Additionally or alternatively, BS 110 may indicate the set of disallowed beamforming directions to UE 120. UE 120 may be permitted to transmit the signal in the configured resource set according to the beamforming direction parameter.

[0091] In some aspects, the beamforming direction can be represented by a codeword in a spatial precoding codebook (such as a transmission precoding matrix indicator (TPMI) value from a TPMI codebook). In some aspects, the beamforming direction can be associated with a reference signal. For example, the beamforming direction can be represented by a downlink reference signal resource (such as a synchronization signal block (SSB) resource or a CSI-RS resource), which means that the beamforming direction is the direction that can be used to achieve the highest signal-to-interference-plus-noise ratio (SINR) in reception on a given reference signal resource, at least partially based on DL-UL reciprocity. As another example, the beamforming direction can be represented by an uplink reference signal resource (such as an SRS resource), which means that the beamforming direction matches the direction used to transmit a signal in this UL reference signal resource.

[0092] In some aspects, BS 110 can indicate the transmit power parameter of the beamforming direction. For example, BS 110 can indicate a beamforming direction parameter and the corresponding transmit power parameter to be used for the beamforming direction. The transmit power parameter can include any of the above transmit power parameters, and the beamforming direction parameter can include any of the above beamforming direction parameters. Thus, BS 110 can configure UE 120 to reduce the transmit power in a given direction, which can reduce the interference at a UE or a node located in the given direction relative to UE 120.

[0093] As described above, in some aspects, BS 110 can provide configuration information to an IAB node to configure the IAB node to measure self-interference. In this case, BS 110 (e.g., the CCN) can configure resources for self-interference measurement for the IAB node as well as the parent node of the IAB node. Thus, the parent node can avoid scheduling transmissions on the parent backhaul link during the resources used for self-interference measurement without interference or scheduling issues. In other aspects, BS 110 (e.g., the parent node of the IAB node) can configure resources for self-interference measurement for the IAB node. For example, for an IAB node that performs MT reception and DU transmission, the parent node can configure resources on the downlink parent backhaul link for self-interference measurement of the IAB node. In this case, the parent node can transmit CSI-RS on the configured resources. As another example, for an IAB node that performs MT transmission and DU reception, the parent node can configure resources on the uplink parent backhaul link for self-interference measurement of the IAB node. In this case, the parent node can schedule SRS on the configured resources.

[0094] As shown by reference numeral 720, the UE 120 may send a signal according to configuration information. For example, depending on the content of the configuration information, the UE 120 may use a specified transmission sequence in a resource set indicated by the configuration information according to a transmission power parameter, and / or send a signal using a beam specified by the configuration information (e.g., in one direction). Therefore, the UE 120 may reduce interference at other UEs or nodes at least partially based on the configuration information. As shown by reference numeral 730, the UE 120 may determine a self-interference measurement at least partially based on the signal. For example, the UE 120 may measure the interference at the resource set indicated by the configuration information and may determine the self-interference measurement at least partially based on the signal. As shown by reference numeral 740, the UE 120 may send information indicating the self-interference measurement to the BS 110. For example, the information indicating the self-interference measurement may indicate a self-interference intensity value (e.g., a value indicating the power level of self-interference), a CSI value calculated at least partially based on the self-interference intensity value, etc.

[0095] As described above, Figure 7 is provided as an example. Other examples may be different from Figure 7 what is described with reference to

[0096] Figure 8 FIG. is a diagram illustrating an example process 800, such as may be performed by a node, in accordance with various aspects of the present disclosure. Example process 800 is an example of operations performed by a node (e.g., UE 120, IAB node 410, etc.) associated with radio resource configuration for self-interference measurement.

[0097] As Figure 8 shown, in some aspects, process 800 may include receiving configuration information indicating a resource set for self-interference measurement associated with a full-duplex communication mode (block 810). For example, as described above, a node (e.g., using antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, controller / processor 280, etc.) may receive configuration information indicating a resource set for self-interference measurement associated with a full-duplex communication mode. In some aspects, the configuration information may include any indication described above in connection with Figure 7 reference numeral 710.

[0098] As Figure 8As shown, in some aspects, process 800 may optionally include determining the transmit power of a signal (block 820) based at least in part on the allowed received power level and at least in part on the path loss value.
