Description

[0001] Cross-reference to related applications

[0002] This patent application claims priority to Greek Patent Application No. 20230100941, filed on November 14, 2023, entitled “INTEGRATED COMMUNICATIONS AND SENSING WITH INTERFERENCE MITIGATION AND CANCELLATION”, which is expressly incorporated herein by reference. Technical Field

[0003] All aspects of this disclosure relate to wireless communication in general, and to techniques and apparatus for integrated communication and sensing with interference mitigation and elimination. Background Technology

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

[0005] A wireless network may include one or more network nodes that support communication for wireless communication devices, such as user equipment (UE) or multiple UEs. UEs may communicate with network nodes via downlink and uplink communication. A "downlink" (or "DL") refers to the communication link from the network node to the UE, and an "uplink" (or "UL") refers to the communication link from the UE to the network node. Some wireless networks may support device-to-device communication, such as via local links (e.g., sidelinks (SL), wireless local area network (WLAN) links, and / or wireless personal area network (WPAN) links).

[0006] The aforementioned multiple access technologies have been adopted in various telecommunications standards to provide a common protocol that enables different UEs to communicate at the city, country, region, and / or global levels. New Radio (NR) (which may be referred to as 5G) is an enhancement set to the LTE mobile standard issued by 3GPP. NR is designed to better support mobile broadband internet access by: improving spectrum efficiency; reducing costs; improving service; utilizing new spectrum; and better integrating with other open standards by using Orthogonal Frequency Division Multiplexing (OFDM) with Cyclic Prefix (CP) on the downlink (CP-OFDM), and CP-OFDM and / or Single Carrier Frequency Division Multiplexing (SC-FDM) (also known as Discrete Fourier Transform Extended OFDM (DFT-s-OFDM)) on the uplink; and supporting beamforming, Multiple-Input Multiple-Output (MIMO) antenna technologies and carrier aggregation. Further improvements to LTE, NR, and other radio access technologies remain useful as the demand for mobile broadband access continues to increase. Summary of the Invention

[0025] Extensions to next-generation (NG) radio access technologies (RATs) such as fifth-generation (5G) (also known as new radio (NR)) and / or sixth-generation (6G) may include adding sensing processes and / or sensing services in conjunction with communication services. Example sensing services may include long-range radar (e.g., radio detection and ranging) sensing processes configured to sense objects more than 250 meters away and / or short-range radar sensing processes configured to sense objects less than 50 meters away. The coexistence of communication transmissions and radar transmissions in a radio access network (RAN) can lead to various types of interference. Some non-limiting examples may include radar-to-radar (Rad-Rad) interference, radar-to-comm (Rad-Comm) interference, and / or communication-to-comm (Comm-Comm) interference. In some aspects, Rad-Rad interference and Rad-Comm interference can affect radar sensing processes in ways different from the effects of Comm-Comm interference on communication processes (e.g., modulation, coding, transmission, reception, demodulation, and / or decoding). Therefore, interference management techniques used to mitigate the effects of Comm-Comm interference may be ineffective in mitigating Rad-Rad interference and / or Rad-Comm interference during radar sensing, and may lead to increased errors and / or inaccuracies during radar sensing. Alternatively or additionally, interference management techniques used to mitigate the effects of Comm-Comm interference may be ineffective in mitigating Rad-Comm interference during communication, and may lead to increased recovery errors, reduced data throughput, and / or increased data transmission latency in wireless networks.

[0026] The various aspects described herein generally relate to Integrated Communications and Sensing (ICS) with Interference Mitigation and Cancellation (IMC). Some aspects more specifically relate to a sensing UE performing a sensing procedure using an ICS conflict detection configuration. The UE can obtain an ICS conflict detection configuration indication associated with the interference sensing procedure. In one example, the UE can obtain the ICS conflict detection configuration indication by receiving it from another UE and / or a network node. In a second example, the UE can obtain the ICS conflict detection configuration indication by generating the ICS conflict detection configuration. The ICS conflict detection configuration indication can specify one or more parameters that can be used to configure the interference sensing procedure. Thus, the UE can perform the interference sensing procedure at least in part based on the use of the ICS conflict detection configuration indication, such as configuring the interface sensing procedure by using parameters. The UE can send ICS interference messages at least in part based on the interference sensing procedure, such as by sending an ICS measurement report indicating one or more ICS measurement metrics generated by the interference sensing procedure and / or by sending inter-UE coordination messages indicating auxiliary information that can mitigate interference detected by the interference sensing procedure.

[0027] A sensing UE receiving an indication of ICS collision detection configuration can mitigate radar-based interference (e.g., Rad-Rad interference and / or Rad-Comm interference) during radar sensing and / or communication processes, as described below. For example, the sensing UE can use the ICS collision detection configuration to identify air interface resources (such as sidelink air interface resources) associated with potential collisions between communication transmissions and radar transmissions, and avoid using those air interface resources. Alternatively or additionally, the sensing UE can forward ICS messages indicating transmission configurations (e.g., radar transmission configurations) and / or air interface resources associated with potential collisions, enabling other devices to avoid using those air interface resources. Using the ICS collision detection configuration and / or ICS messages enables the sensing device and / or another wireless communication device to mitigate radar-based interference, thereby achieving reliable monostation radar sensing and / or bistation communication in the sidelink. For illustration, mitigating radar-based interference can improve radar sensing accuracy in monostation radar sensing, reduce bit errors in bistation communication, increase data throughput in bistation communication, and / or reduce data transmission latency in bistation communication.

[0028] Various aspects of this disclosure are described more fully below with reference to the accompanying drawings. However, this disclosure may be embodied in many different forms and should not be construed as limited to any particular structure or function presented throughout this disclosure. Rather, these aspects are provided so that this disclosure will be comprehensive and complete, and will fully convey the scope of protection of this disclosure to those skilled in the art. Those skilled in the art will appreciate that the scope of this disclosure is intended to cover any aspect of this disclosure disclosed herein, whether implemented independently or in combination with any other aspect of this disclosure. For example, any number of aspects set forth herein may be used to implement an apparatus or method of practice. Furthermore, the scope of this disclosure is intended to cover such apparatuses or methods implemented using structures, functions, or structures and functions other than or different from the various aspects of the disclosure set forth herein. It should be understood that any aspect of the disclosure herein may be embodied by one or more elements of the claims.

[0029] Various devices and techniques will now be used to illustrate several aspects of a telecommunications system. These devices and techniques will be described in detail below and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, or algorithms (collectively, “elements”). These elements can be implemented using hardware, software, or a combination thereof. Whether these elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the system as a whole.

[0030] Although terms generally associated with 5G or New Radio (NR) Radio Access Technology (RAT) may be used herein to describe aspects, aspects of this disclosure may be applied to other RATs, such as 3G RAT, 4G RAT and / or 5G and later (e.g., 6G) RATs.

[0031] Figure 1 This is a diagram illustrating an example of a wireless network 100 according to the present disclosure. The wireless network 100 may be a 5G (e.g., NR) network and / or a 4G (e.g., Long Term Evolution (LTE)) network, or may include elements of a 5G (e.g., NR) network and / or elements of a 4G (e.g., LTE) network, etc. The wireless network 100 may include one or more network nodes 110 (shown as network node 110a, network node 110b, network node 110c, and network node 110d), one or more UEs 120 (shown as UE 120a, UE 120b, UE 120c, UE 120d, and UE 120e), and / or other entities. Network node 110 is a network node that communicates with UE 120. As shown, network node 110 may include one or more network nodes. For example, network node 110 can be an aggregated network node, meaning that an aggregated network node is configured to utilize a radio protocol stack that is physically or logically integrated within a single radio access network (RAN) node (e.g., within a single device or unit). As another example, network node 110 can be a decomposed network node (sometimes referred to as a decomposed base station), meaning that network node 110 is configured to utilize a protocol stack that is physically or logically distributed among two or more nodes (such as one or more central units (CUs), one or more distributed units (DUs), or one or more radio units (RUs)).

[0032] In some examples, network node 110 is or includes network nodes (such as RUs) that communicate with UE 120 via a radio access link. In some examples, network node 110 is or includes network nodes (such as DUs) that communicate with other network nodes 110 via a fronthaul or midhaul link. In some examples, network node 110 is or includes network nodes (such as CUs) that communicate with other network nodes 110 via a midhaul link or with the core network via a backhaul link. In some examples, network node 110 (such as aggregated network node 110 or decomposed network node 110) may include multiple network nodes, such as one or more RUs, one or more CUs, and / or one or more DUs. Network node 110 may include, for example, NR base stations, LTE base stations, Node Bs, eNBs (e.g., in 4G), gNBs (e.g., in 5G), access points, Transmit / Receive Points (TRPs), DUs, RUs, CUs, network mobility elements, core network nodes, network elements, network equipment, RAN nodes, or combinations thereof. In some examples, network nodes 110 can interconnect with each other or with one or more other network nodes 110 in the wireless network 100 using any suitable transport network through various types of fronthaul interfaces, midhaul interfaces, and / or backhaul interfaces (such as direct physical connections, air interfaces, or virtual networks).

[0033] In some examples, network node 110 may provide communication coverage for a specific geographic area. In the 3rd Generation Partnership Project (3GPP), the term "cell" may refer to the coverage area of ​​network node 110 and / or the network node subsystem serving that coverage area, depending on the context in which the term is used. Network node 110 may provide communication coverage for macrocells, picocells, femtocells, and / or another type of cell. A macrocell may cover a relatively large geographic area (e.g., with a radius of several kilometers) and may allow unrestricted access by UE 120 with a service subscription. A picocell may cover a relatively small geographic area and may allow unrestricted access by UE 120 with a service subscription. A femtocell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by UE 120 associated with the femtocell (e.g., UE 120 in a Closed Subscriber Group (CSG)). Network node 110 used for macrocells may be referred to as a macro network node. Network node 110 used for picocells may be referred to as a pico network node. The network node 110 used for femtocells can be referred to as a femtocell network node or a home network node. Figure 1In the example shown, network node 110a can be a macro network node for macro cell 102a, network node 110b can be a pico network node for pico cell 102b, and network node 110c can be a femto network node for femto cell 102c. Network nodes can support one or more (e.g., three) cells. In some examples, the cells may not necessarily be stationary, and the geographical area of ​​the cells may move depending on the location of the mobile network node 110 (e.g., a mobile network node).

[0034] In some aspects, the term "base station" or "network node" may refer to an aggregated base station, a decomposed base station, an integrated access and backhaul (IAB) node, a relay node, or one or more components thereof. For example, in some aspects, "base station" or "network node" may refer to a CU, DU, RU, a near real-time (near RT) RAN intelligent controller (RIC), or a non-real-time (non-RT) RIC, or a combination thereof. In some aspects, the term "base station" or "network node" may refer to a device configured to perform one or more functions (such as those described herein in conjunction with network node 110). In some aspects, the term "base station" or "network node" may refer to multiple devices configured to perform one or more functions. For example, in some distributed systems, each of multiple different devices (which may be located in the same geographical location or different geographical locations) may be configured to perform at least a portion of a function, or to repeatedly perform at least a portion of that function, and the term "base station" or "network node" may refer to any one or more of these different devices. In some aspects, the term "base station" or "network node" may refer to one or more virtual base stations or one or more virtual base station functions. For example, in some aspects, two or more base station functions can be instantiated on a single device. In some aspects, the term "base station" or "network node" may refer to one base station function rather than another. Thus, a single device can include more than one base station.

[0035] Wireless network 100 may include one or more relay stations. A relay station is a network node that can receive data transmissions from upstream nodes (e.g., network node 110 or UE 120) and transmit data to downstream nodes (e.g., UE 120 or network node 110). A relay station may be a UE 120 that can relay transmissions for other UE 120s. Figure 1 In the example shown, network node 110d (e.g., a relay network node) can communicate with network node 110a (e.g., a macro network node) and UE 120d to facilitate communication between network node 110a and UE 120d. The network node 110 for relay communication may be referred to as a relay station, relay base station, relay network node, relay node, or repeater, etc.

[0036] The wireless network 100 can be a heterogeneous network, comprising different types of network nodes 110, such as macro network nodes, pico network nodes, femto network nodes, or relay network nodes. These different types of network nodes 110 may have different transmit power levels, different coverage areas, and / or different effects on interference in the wireless network 100. For example, macro network nodes may have high transmit power levels (e.g., 5 watts to 40 watts), while pico network nodes, femto network nodes, and relay network nodes may have lower transmit power levels (e.g., 0.1 watts to 2 watts).

[0037] Network controller 130 may be coupled to or communicate with network node set 110, and may provide coordination and control for these network nodes 110. Network controller 130 may communicate with network nodes 110 via a backhaul or midhaul link. Network nodes 110 may also communicate directly with each other, or indirectly via a wireless or wired backhaul link. In some aspects, network controller 130 may be a CU or core network device, or may include a CU or core network device.

[0038] UE 120 may be distributed throughout the wireless network 100, and each UE 120 may be stationary or mobile. UE 120 may include, for example, access terminals, terminals, mobile stations, and / or subscriber units. UE 120 may be a cellular phone (e.g., a smartphone), 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 smartwatch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring or 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, industrial manufacturing equipment, a GPS device, a UE function of a network node, and / or any other suitable device configured to communicate via wireless or wired media.

[0039] Some UEs 120 may be considered machine-type communication (MTC) or evolved or enhanced machine-type communication (eMTC) UEs. MTC UEs and / or eMTC UEs may include, for example, robots, unmanned aerial vehicles, remote devices, sensors, instruments, monitors, and / or location tags that can communicate with network nodes, another device (e.g., a remote device), or some other entity. Some UEs 120 may be considered Internet of Things (IoT) devices and / or may be implemented as NB-IoT (Narrowband IoT) devices. Some UEs 120 may be considered customer premises equipment. UEs 120 may be included within a housing that houses the components of the UE 120, such as processor components and / or memory components. In some examples, the processor components and memory components may be coupled together. For example, the processor components (e.g., one or more processors) and memory components (e.g., memory) may be operatively coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0040] Generally, any number of wireless networks 100 can be deployed in a given geographical area. Each wireless network 100 can support a specific RAT and can operate on one or more frequencies. A RAT may be referred to as a radio technology or air interface, etc. A frequency may be referred to as a carrier or frequency channel, etc. Each frequency in a given geographical area can support a single RAT to avoid interference between wireless networks using different RATs. In some cases, NR or 5G RAT networks can be deployed.

[0041] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more sidelink channels (e.g., without using network node 110 as an intermediary device to communicate with each other). For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, or vehicle-to-pedestrian (V2P) protocols) and / or mesh networks. In such examples, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by network node 110.

[0042] Devices in Wireless Network 100 can communicate using the electromagnetic spectrum, which can be subdivided into various categories, bands, or channels based on frequency or wavelength. For example, devices in Wireless Network 100 can communicate using one or more operating bands. In 5G NR, two initial operating bands have been designated as frequency ranges FR1 (410MHz to 7.125GHz) and FR2 (24.25GHz to 52.6GHz). It should be understood that although a portion of FR1 is greater than 6GHz, FR1 is often (interchangeably) referred to as the “sub-6GHz” band in various documents and articles. Similar naming issues sometimes occur with FR2, which is often (interchangeably) referred to as the “millimeter wave” band in documents and articles, although this is different from the Extremely High Frequency (EHF) band (30GHz to 300GHz) designated as a “millimeter wave” band by the International Telecommunication Union (ITU).

[0043] The frequencies between FR1 and FR2 are generally referred to as intermediate frequency (IF) bands. Recent 5G NR studies have designated the operating bands for these IF bands as the frequency range designation FR3 (7.125 GHz – 24.25 GHz). Bands falling within FR3 can inherit FR1 and / or FR2 characteristics, thus effectively extending the features of FR1 and / or FR2 to IF band frequencies. Additionally, higher frequency bands are currently being explored to extend 5G NR operation beyond 52.6 GHz. For example, three higher operating bands have been designated as the frequency range designations FR4a or FR4-1 (52.6 GHz to 71 GHz), FR4 (52.6 GHz to 114.25 GHz), and FR5 (114.25 GHz to 300 GHz). Each of these higher frequency bands falls within the EHF band.

[0044] Considering the examples above, unless otherwise specifically stated, it should be understood that when the term "below 6 GHz" is used herein, it can broadly refer to frequencies below 6 GHz, within FR1, or including intermediate frequency band frequencies. Furthermore, unless otherwise specifically stated, it should be understood that when the term "millimeter wave" is used herein, it can broadly refer to frequencies that can include intermediate frequency band frequencies, within FR2, FR4, FR4-a, or FR4-1 and / or FR5, or within the EHF band. Modifications to frequencies included in these operating frequency bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, and / or FR5) are contemplated, and the techniques described herein are applicable to those modified frequency ranges.

[0045] In some aspects, the UE (e.g., UE 120) may include a communication manager 140. As described in more detail elsewhere herein, the communication manager 140 may obtain an ICS conflict detection configuration indication associated with an interference sensing procedure; use the ICS conflict detection configuration indication to perform the interference sensing procedure; and send ICS interference messages based at least in part on the interference sensing procedure. Additionally or alternatively, the communication manager 140 may perform one or more other operations described herein.

[0046] As indicated above, Figure 1 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 1 The examples described are different.

[0047] Figure 2 This is a diagram illustrating example 200 of communication between network node 110 and UE 120 in a wireless network 100 according to this disclosure. Network node 110 may be equipped with antenna sets 234a to 234t, such as T antennas (T≥1). UE 120 may be equipped with antenna sets 252a to 252r, such as R antennas (R≥1). Network node 110 of example 200 includes one or more radio frequency components, such as antenna 234 and modem 232. In some examples, network node 110 may include an interface, communication components, or another component facilitating communication with UE 120 or another network node. Some network nodes 110 may not include radio frequency components facilitating direct communication with UE 120, such as one or more CUs or one or more DUs.

[0048] At network node 110, transmitting processor 220 can receive data from data source 212 intended for use by UE 120 (or UE set 120). Transmitting processor 220 can select one or more modulation and decoding schemes (MCS) for UE 120 based at least in part on one or more channel quality indicators (CQIs) received from UE 120. Network node 110 can process (e.g., encode and modulate) the data for UE 120 based at least in part on the MCS selected for UE 120 and can provide data symbols for UE 120. Transmitting processor 220 can process system information (e.g., for semi-static resource allocation information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper-layer signaling) and provide overhead symbols and control symbols. Transmitting processor 220 can generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signal (PSS) or secondary synchronization signal (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 can perform spatial processing (e.g., pre-decoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, where applicable, and can provide a set of output symbol streams (e.g., T output symbol streams) to a corresponding set of modems 232 (e.g., T modems) (shown as modems 232a to 232t). For example, each output symbol stream can be provided to a modulator component (shown as MOD) of modem 232. Each modem 232 can use a corresponding modulator component to process the corresponding output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modem 232 can also use a corresponding modulator component to process the output sample stream (e.g., convert to analog, amplify, filter, and / or up-convert) to obtain a downlink signal. Modems 232a to 232t can transmit a set of downlink signals (e.g., T downlink signals) via a corresponding set of antennas 234 (e.g., T antennas) (shown as antennas 234a to 234t).

[0049] At UE 120, antenna set 252 (shown as antennas 252a to 252r) can receive downlink signals from network node 110 and / or other network nodes 110 and can provide a set of received signals (e.g., R received signals) to modem set 254 (e.g., R modems) (shown as modems 254a to 254r). For example, each received signal can be provided to a demodulator component (shown as DEMOD) of modem 254. Each modem 254 can use a corresponding demodulator component to condition (e.g., filter, amplify, downconvert, and / or digitize) the received signal to obtain an input sample. Each modem 254 can use the demodulator component to further process the input sample (e.g., for OFDM) to obtain a received symbol. MIMO detector 256 can obtain the received symbols from modem 254, perform MIMO detection on the received symbols where applicable, and provide the detected symbols. The receiver processor 258 can process (e.g., demodulate and decode) the detected symbols, provide the decoded data for UE 120 to data sink 260, and provide the decoded control information and system information to controller / processor 280. The term "controller / processor" can refer to one or more controllers, one or more processors, or a combination thereof. The channel processor can determine Reference Signal Received Power (RSRP) parameters, Received Signal Strength Indicator (RSSI) parameters, Reference Signal Received Quality (RSRQ) parameters, and / or CQI parameters, etc. In some examples, one or more components of UE 120 may be included in housing 284.

[0050] Network controller 130 may include communication unit 294, controller / processor 290, and memory 292. Network controller 130 may include one or more devices, for example, in a core network. Network controller 130 may communicate with network node 110 via communication unit 294.

[0051] One or more antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include 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., or may 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), coplanar antenna element sets, non-coplanar antenna element sets, and / or be coupled to one or more transmitting and / or receiving components (such as...). Figure 2 One or more antenna elements (one or more components in a )

[0052] On the uplink, at UE 120, the transmit processor 264 can receive and process data from data source 262 and control information from controller / processor 280 (e.g., for reporting including RSRP, RSSI, RSRQ, and / or CQI). The transmit processor 264 can generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 can be pre-decoded by the TX MIMO processor 266 where applicable, further processed by the modem 254 (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to network node 110. In some examples, the modem 254 of UE 120 may include a modulator and demodulator. In some examples, UE 120 includes a transceiver. The transceiver may include any combination of antenna 252, modem 254, MIMO detector 256, receive processor 258, transmit processor 264, and / or TX MIMO processor 266. The transceiver may be used by a processor (e.g., controller / processor 280) and memory 282 to execute this document (e.g., reference). Figures 6 to 9 ( ) any aspect of the methods described in the method.

[0053] At network node 110, uplink signals from UE 120 and / or other UEs may be received by antenna 234, processed by modem 232 (e.g., demodulator component of modem 232 (shown as DEMOD)), detected by MIMO detector 236 (where applicable), and further processed by receive processor 238 to obtain decoded data and control information transmitted by UE 120. Receive processor 238 may provide the decoded data to data sink 239 and the decoded control information to controller / processor 240. Network node 110 may include communication unit 244 and may communicate with network controller 130 via communication unit 244. Network node 110 may include scheduler 246 for scheduling one or more UEs 120 for downlink and / or uplink communication. In some examples, modem 232 of network node 110 may include modulator and demodulator. In some examples, network node 110 includes transceiver. The transceiver may include any combination of antenna 234, modem 232, MIMO detector 236, receive processor 238, transmit processor 220, and / or TX MIMO processor 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to execute this document (e.g., reference). Figures 6 to 9 ( ) any aspect of the methods described in the method.

[0054] The controller / processor 240 of network node 110, the controller / processor 280 of UE 120 and / or Figure 2 Any other component may perform one or more technologies associated with an ICS having an IMC, as described in more detail elsewhere herein. For example, the controller / processor 240 of network node 110, the controller / processor 280 of UE 120, and / or Figure 2 Any other component that can execute or direct, for example Figure 8 The operation of process 800 and / or other processes as described herein. Memory 242 and memory 282 may store data and program code for network node 110 and UE 120, respectively. In some examples, memory 242 and / or 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, the one or more instructions may cause the one or more processors, UE 120 and / or network node 110 to perform or direct, for example, when executed by one or more processors of network node 110 and / or UE 120 (e.g., directly, or after compilation, transformation and / or interpretation). Figure 8 The operation of process 800 and / or other processes as described herein. In some examples, the execution instructions may include run instructions, transformation instructions, compilation instructions, and / or interpretation instructions, etc.

[0055] In some aspects, the UE (e.g., UE 120) includes: components for obtaining an ICS conflict detection configuration indication at least in part based on the interference sensing process; components for performing the interference sensing process using the ICS conflict detection configuration indication; and / or components for transmitting an ICS interference message at least in part based on the interference sensing process. Components for the UE to perform the operations described herein may include, for example, one or more of the following: a communication manager 140, an antenna 252, a modem 254, a MIMO detector 256, a receive processor 258, a transmit processor 264, a TX MIMO processor 266, a controller / processor 280, or a memory 282.

[0056] In some respects, a single processor can perform all functions described as being executed by the one or more processors. In other respects, the one or more processors can jointly execute a set of functions. For example, a first set of processors(s) of the one or more processors can perform a first function described as being executed by the one or more processors, and a second set of processors(s) of the one or more processors can perform a second function described as being executed by the one or more processors. The first set of processors and the second set of processors can be the same set of processors or they can be different sets of processors. The reference to "one or more processors" should be understood as referring to a combination of processors. Figure 2 Any one or more processors described. The reference to "one or more memories" should be understood to refer to any one or more memories of the corresponding device, such as those in conjunction with... Figure 2 The memory described. For example, a function described as being performed by one or more memories may be performed by the same one or more subsets of memories or by different one or more subsets of memories.

[0057] Although Figure 2 The boxes in the diagram are illustrated as different components, but the functions described above with respect to these boxes may be implemented in a single hardware, software, or combined component, or in various combinations of components. For example, the functions described with respect to transmit processor 264, receive processor 258, and / or TX MIMO processor 266 may be performed by or under the control of controller / processor 280.

[0058] As indicated above, Figure 2 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 2 The examples described are different.

[0059] The deployment of communication systems such as 5G NR systems can be arranged in a variety of ways using various components or parts. In a 5G NR system or network, network nodes, network entities, network mobility elements, RAN nodes, core network nodes, network elements, base stations, or network equipment can be implemented in either a converged or decomposed architecture. For example, a base station (such as a Node B (NB), evolved NB (eNB), NR base station, 5G NB, access point (AP), TRP, or cell, etc.) or one or more units (or components) performing base station functionality can be implemented as a converged base station (also known as a standalone base station or monolithic base station) or a decomposed base station. A "network entity" or "network node" can refer to a decomposed base station or one or more units of a decomposed base station (such as one or more CUs, one or more DUs, one or more RUs, or combinations thereof).

[0060] Aggregated base stations (e.g., aggregated network nodes) can be configured to utilize a radio protocol stack that is physically or logically integrated within a single RAN node (e.g., within a single device or cell). Decomposed base stations (e.g., decomposed network nodes) can be configured to utilize a protocol stack that is physically or logically distributed across two or more cells (such as one or more CUs, one or more DUs, or one or more RUs). In some examples, the CU may be implemented within a network node, and one or more DUs may be co-located with the CU, or alternatively, may be geographically or virtually distributed across one or more other network nodes. DUs may be implemented to communicate with one or more RUs. Each of the CU, DU, and RU may also be implemented as a virtual cell, such as a Virtual Central Unit (VCU), Virtual Distributed Unit (VDU), or Virtual Radio Unit (VRU), etc.

[0061] Base station type operation or network design can take into account the aggregation characteristics of base station functionality. For example, decomposed base stations can be utilized in IAB networks, Open Radio Access Networks (O-RAN (such as network configurations initiated by the O-RAN Alliance)), or Virtualized Radio Access Networks (vRAN, also known as Cloud Radio Access Networks (C-RAN)) to facilitate the scaling of communication systems by separating base station functionality into one or more units that can be deployed independently. Decomposed base stations can include functionality implemented across two or more units at various physical locations, as well as functionality virtually implemented for at least one unit, which enables flexibility in network design. Each unit of a decomposed base station can be configured for wired or wireless communication with at least one other unit of the decomposed base station.

[0062] Figure 3 This is an illustration of an example disaggregated base station architecture 300 according to this disclosure. The disaggregated base station architecture 300 may include a CU 310, which may communicate directly with the core network 320 via a backhaul link, or indirectly with the core network 320 via one or more disaggregated control units (such as near-RT RIC 325 via an E2 link, or a non-RT RIC 315 associated with a Service Management and Orchestration (SMO) framework 305, or both). The CU 310 may communicate with one or more DUs 330 via a corresponding midhaul link (such as via an F1 interface). Each DU 330 may communicate with one or more RUs 340 via a corresponding fronthaul link. Each RU 340 may communicate with one or more UEs 120 via a corresponding radio frequency (RF) access link. In some implementations, a UE 120 may be served simultaneously by multiple RUs 340.

[0063] Each unit in the cells (including CU 310, DU 330, RU 340), as well as the near-RT RIC 325, non-RT RIC 315, and SMO frame 305, may include or be coupled to one or more interfaces configured to receive or transmit signals, data, or information (collectively, signals) via wired or wireless transmission media. Each unit in the cell, or an associated processor or controller providing instructions to one or more communication interfaces of the corresponding unit, may be configured to communicate with one or more units in other cells via transmission media. In some examples, each unit in the cell may include a wired interface and a wireless interface configured to receive signals or transmit signals to one or more units in other cells via a wired transmission media, and the wireless interface may include a receiver, transmitter, or transceiver (such as an RF transceiver) configured to receive signals or transmit signals to one or more units in other cells via a wireless transmission media, or both.

[0064] In some aspects, the CU 310 can host one or more higher-level control functions. Such control functions may include Radio Resource Control (RRC) functions, Packet Data Convergence Protocol (PDCP) functions, or Service Data Adaptation Protocol (SDAP) functions, etc. Each control function can be implemented using an interface configured to signal to other control functions hosted by the CU 310. The CU 310 can be configured to handle user plane functions (e.g., Central Unit-User Plane (CU-UP) functions), control plane functions (e.g., Central Unit-Control Plane (CU-CP) functions), or combinations thereof. In some implementations, the CU 310 can be logically split into one or more CU-UP units and one or more CU-CP units. When implemented in an O-RAN configuration, the CU-UP units can communicate bidirectionally with the CU-CP units via an interface such as an E1 interface. The CU 310 can be implemented to communicate with the DU 330 for network control and signaling purposes, as needed.

[0065] Each DU 330 may correspond to a logical unit comprising one or more base station functions for controlling the operation of one or more RU 340s. In some aspects, the DU 330 may host one or more of the Radio Link Control (RLC) layer, Medium Access Control (MAC) layer, and one or more high physical (PHY) layers, at least in part, according to functional splits (such as those defined by 3GPP). In some aspects, the one or more high PHY layers may be implemented by one or more modules for forward error correction (FEC) encoding and decoding, scrambling, and modulation and demodulation. In some aspects, the DU 330 may also host one or more low PHY layers, such as those implemented by one or more modules for Fast Fourier Transform (FFT), Inverse FFT (iFFT), Digital Beamforming, or Physical Random Access Channel (PRACH) extraction and filtering. Each layer (which may also be referred to as a module) may be implemented using an interface configured to communicate signals with other layers (and modules) hosted by the DU 330 or with control functions hosted by the CU 310.

[0066] Each RU 340 can implement lower-layer functionality. In some deployments, an RU 340 controlled by a DU 330 can correspond to a logical node that hosts RF processing functions or low-PHY layer functions, such as performing FFT, performing iFFT, digital beamforming, or PRACH extraction and filtering, based on function splitting (e.g., function splitting defined by 3GPP) (such as lower-layer function splitting). In such architectures, each RU 340 can be operated to handle over-the-air (OTA) communications with one or more UEs 120. In some specific implementations, the real-time and non-real-time aspects of control plane and user plane communications with the RU 340 can be controlled by the corresponding DU 330. In some scenarios, this configuration allows each DU 330 and CU 310 to be implemented in a cloud-based RAN architecture, such as a vRAN architecture.

[0067] The SMO framework 305 can be configured to support RAN deployment and provisioning of both non-virtualized and virtualized network elements. For non-virtualized network elements, the SMO framework 305 can be configured to support the deployment of dedicated physical resources for RAN coverage requirements, which can be managed via operation and maintenance interfaces such as the O1 interface. For virtualized network elements, the SMO framework 305 can be configured to interact with cloud computing platforms such as the Open Cloud (O-Cloud) platform 390 to perform network element lifecycle management (such as instantiating virtualized network elements) via cloud computing platform interfaces such as the O2 interface. Such virtualized network elements may include, but are not limited to, CU 310, DU 330, RU 340, non-RT RIC 315, and near-RTTRIC 325. In some specific implementations, the SMO framework 305 may communicate with 4G RAN hardware aspects such as the Open eNB (O-eNB) 311 via the O1 interface. Additionally, in some implementations, the SMO framework 305 can communicate directly with each of one or more RUs 340 via a corresponding O1 interface. The SMO framework 305 may also include a non-RT RIC 315 configured to support the functionality of the SMO framework 305.

[0068] The non-RT RIC 315 can be configured to include logical functions that enable non-real-time control and optimization of RAN elements and resources, including artificial intelligence / machine learning (AI / ML) workflows for model training and updates, or policy-based guidance for applications / features in the near-RT RIC 325. The non-RT RIC 315 can be coupled to or communicate with the near-RT RIC 325, such as via an A1 interface. The near-RT RIC 325 can be configured to include logical functions that enable near real-time control and optimization of RAN elements and resources via an interface, such as an E2 interface, through data collection and actions, connecting one or more CU 310s, one or more DU 330s, or both, and O-eNBs to the near-RT RIC 325.

[0069] In some implementations, to generate AI / ML models to be deployed in the near-RT RIC 325, the non-RT RIC 315 may receive parameters or external enrichment information from an external server. This information can be utilized by the near-RT RIC 325 and can be received from non-network data sources or network functions at the SMO framework 305 or the non-RT RIC 315. In some examples, the non-RT RIC 315 or near-RT RIC 325 may be configured to tune RAN behavior or performance. For example, the non-RT RIC 315 may monitor long-term trends and patterns in performance and employ AI / ML models to perform corrective actions via the SMO framework 305 (such as reconfiguration via the O1 interface) or via the creation of RAN management policies (such as A1 interface policies).

[0070] As indicated above, Figure 3 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 3 The examples described are different.

[0071] Figure 4 This is an illustration of Example 400 of the Joint Communications Radar (JCR) system according to this disclosure.

[0072] In some examples, network devices (e.g., UE 120, network node 110, or similar network devices) may include JCR capabilities and / or include a JCR system. A JCR system may be a system capable of sharing a frequency band between radar and communication systems within the network device. In some instances, a JCR system may be classified as a collaborative JCR system (as schematically shown by reference numeral 402) or a co-designed JCR system (as schematically shown by reference numeral 404).

[0073] In a cooperative JCR system, network devices such as the first device 406 and the second device 408 may include separate radar and communication systems. For example, the first device 406 may include radar system 410 and communication system 412, and the second device 408 may similarly include radar system 414 and communication system 416. In such cases, information can be shared between radar systems 410, 414 and their corresponding communication systems 412, 416 to improve system performance without altering the core operations of the respective systems. In some cases, the benefits of implementing a cooperative JCR system compared to other JCR systems include spectrum reuse and ease of implementation.

[0074] In a collaboratively designed JCR system, network devices such as the first device 418 and the second device 420 may include a common transmitter and / or receiver for both communication and radar functions. For example, the first device 418 may include a JCR transmitter / receiver 422, and the second device 420 may similarly include a JCR transmitter / receiver 424. In such respects, the JCR transmitters / receivers 422, 424 may include functionality for generating various transmitted waveforms (e.g., waveforms applicable to radar functionality and waveforms applicable to communication functionality) and / or functionality for processing received waveforms for radar and / or communication systems. In some cases, the benefits achieved by implementing a collaboratively designed JCR system include spectrum reuse and hardware reuse.

[0075] In some cases, the communication capability of a JCR system can utilize one type of waveform (such as CP-OFDM waveform), and the radar capability of a JCR system can utilize another type of waveform (such as Time Division Multiplexing (TDM) waveform). However, in other cases, both the communication capability and radar capability of a JCR system can utilize the same waveform (such as CP-OFDM waveform).

[0076] As indicated above, Figure 4 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 4 The examples described are different.

[0077] Figure 5 This is a diagram illustrating example 500 of sensing performed by a UE according to this disclosure.

[0078] In some aspects, the UE may perform a sensing process to detect the presence of an object. Alternatively or additionally, the sensing process may detect one or more characteristics of the object, such as shape, size, and / or velocity. An example of a sensing process may include a radar sensing process. The UE performing the radar sensing process (e.g., UE 120) may transmit an RF signal reflected from the object. The UE may receive the reflected RF signal and apply one or more signal processing techniques (e.g., radar signal processing techniques) to the reflected signal to calculate and / or obtain information (e.g., characteristics) about the object. That is, the UE may sense characteristics about the object at least in part based on processing the reflected RF signal.

[0079] Figure 5An example is illustrated of a vehicle-type UE (e.g., a vehicle UE) capable of performing sensing processes (e.g., radar sensing processes) to sense and / or detect surrounding objects. For example, the UE can perform sensing processes as part of automotive applications, such as collision detection applications and / or collision avoidance applications. For illustration, a first vehicle UE 502 can travel in a first direction at a first rate and / or speed of 12 m / s, and a second vehicle UE 504 can also travel in the first direction at a second rate of 20 m / s. The first vehicle UE 502 and the second vehicle UE 504 can be separated by a distance of X meters. Figure 5 (Not shown in the image). For example... Figure 5 As shown, the third vehicle UE 506 can travel at a third speed of 20 m / s in a second direction (e.g., in a direction substantially opposite to the first direction).

[0080] In some respects, the first vehicle UE 502 can send data to field 510 (by... Figure 5 The CP-OFDM signal 508 (shown as having a triangular shape) is associated with the field 510. Field 510 may represent the field of view (FOV) associated with an instantaneous area that can be sensed at a point in time by a radar sensing process and / or the CP-OFDM signal 508, and / or at least partially based on a sweeping process (such as those described below). Figure 6 The described sweeping process is a field of interest (FOR) of the total area that can be sensed by the radar sensing process and / or the CP-OFDM signal 508. Based at least in part on the transmission of the CP-OFDM signal 508, the first vehicle UE 502 can detect radar echo 512 associated with the second vehicle UE 504. In some aspects, the radar echo 512 may be based at least in part on a CP-OFDM signal, such as a reflection of a CP-OFDM signal from the second vehicle UE 504. Alternatively or additionally, the first vehicle UE 502 can detect radar echo 514 associated with the third vehicle UE 506, and the radar echo 514 may be based at least in part on a CP-OFDM signal (e.g., a second reflection of a CP-OFDM signal from the third vehicle UE 506). Based at least in part on radar echo 512 and / or radar echo 514, the first vehicle UE 502 may be able to detect the second vehicle UE 504 and / or the third vehicle UE 506. For example, the first vehicle UE 502 may calculate, at least in part, the corresponding presence, corresponding speed, and / or corresponding distance associated with the second vehicle UE 504 and / or the third vehicle UE 506 based on applying one or more radar signal processing techniques to radar echo 512 and / or radar echo 514, respectively.

[0081] In some aspects, one or more uplink resources can be reused for sensing procedures performed by the UE as at least part of JCR sensing performed by the UE (e.g., UE-side JCR sensing). For example, uplink resources can be shared between a communication mode performed by a first UE and a radar mode performed by a second UE. As an example, uplink resources can be shared between the communication mode and the radar mode, at least in part based on the use of Time Division Multiplexing (TDM). In some aspects, and at least in part based on the use of TDM, a Sounding Reference Signal (SRS) can be used as a sensing waveform (e.g., a waveform used to detect the presence and / or characteristics of an object). As a second example, the same resources can be used for both communication and radar with jointly designed waveforms (e.g., waveform types that can be used as communication and radar waveforms). That is, the communication waveform and the radar waveform can share the same air interface resources, at least in part based on the jointly designed waveform.

[0082] As indicated above, Figure 5 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 5 The examples described are different.

[0083] Figure 6 This is a diagram illustrating example 600 of an uplink sensing process according to the present disclosure.

[0084] Some use cases (such as about) Figure 5 The described automotive use case may involve a relatively high density of radar systems operating at a higher resolution and / or a higher update rate compared to other radar systems. For example, a vehicle radar system may use a first resolution and / or a first update rate that enables it to detect approaching objects (e.g., range accuracy within 180 meters and / or up to 0.725 meters), and an over-the-horizon radar system may operate at a second resolution and / or a second update rate to detect objects beyond line of sight (e.g., range accuracy within 20-40 km and / or up to 2-4 km). Alternatively or additionally, the vehicle radar system may operate in an environment that includes a higher density of radar systems (e.g., three or more radar systems) compared to other radar systems (e.g., fixed radar systems). For example, the mobile nature of the vehicle radar system may cause multiple vehicle radar systems to operate near each other, resulting in the vehicle radar system observing more interference originating from other radar systems.

[0085] In some respects, a single-stage uplink sensing configuration can utilize more communication overhead compared to a two-stage uplink sensing configuration. For example, for the same update rate, a single-stage uplink sensing configuration can allocate 10% of the air interface resources per beam and / or per user (e.g., during sensing) to signaling communication overhead, while a two-stage sensing configuration can allocate 9% of the air interface resources per user to signaling communication overhead. Therefore, a first radar system configured with a single-stage uplink sensing configuration can utilize more air interface resources compared to a second radar system configured with a two-stage uplink sensing configuration. Thus, two-stage uplink sensing may be more suitable for multi-radar sensing using shared uplink communication resources. That is, at least in part, based on the fact that a two-stage uplink sensing configuration uses fewer air interface resources for overhead compared to single-stage uplink sensing, two-stage uplink sensing can better achieve JCR sensing using shared uplink resources compared to single-stage uplink sensing.

[0086] For illustration, a single-stage uplink sensing process, as shown by reference numeral 602, may be based at least in part on a coherent processing interval (CPI) 606, where the CPI may be a radar frame, and each radar frame may be associated with one or more operating conditions and / or one or more configuration boundaries. Example CPI (per beam) conditions may include a CPI duration of 5.1 milliseconds (msec) associated with a bandwidth of 0.5 GHz and a subcarrier spacing (SCS) of 120 kHz for a use case associated with sensing at a carrier frequency of 73 GHz with a velocity resolution of 0.4 m / s and a range resolution of 30 cm.

[0087] like Figure 6 As shown, a single-stage uplink sensing process can sweep through multiple beams, shown as beams 608-1, 608-2 to 608-n, where n is an integer, and each beam can be associated with a corresponding CPI. That is, the single-stage uplink sensing process can be at least partially based on multiple CPIs, and each CPI can be associated with a corresponding beam among the multiple beams. Therefore, for an update rate of 20 frames per second (fps) associated with a 50 ms sensing cycle used for the single-stage sensing process, each beam and each user can use approximately 10% of the system resources.

[0088] The two-stage uplink sensing process, as shown by reference numeral 604 in the accompanying drawings, may include a scanning phase 610 and a tracking phase 612. The scanning phase 610 may be at least partially based on a scanning CPI 614 and a low-resolution beam 616. That is, the low-resolution beam 616 may have a first configuration associated with detecting the presence of a target, but does not detect high-resolution characteristics associated with the target (e.g., velocity resolution of 0.4 m / s and / or range resolution of 30 cm). Therefore, the scanning phase 610 may be used by a device (e.g., a UE) to detect the presence of a target. Figure 6 As shown, scanning phase 610 may include multiple scanning CPIs and beam sweeps, such that each CPI can be associated with a corresponding beam. Example operating conditions and / or configuration boundaries associated with scanning phase 610 may include a scanning CPI with a duration of 1 msec associated with a 150 MHz bandwidth and a 120 kHz SCS, producing a velocity resolution of 2 m / s and a range resolution of 1 meter.

[0089] Tracking phase 612 may be based at least in part on tracking CPI 618 and high-resolution beam 620. In some aspects, high-resolution beam 620 may have a second configuration associated with the detection of refined and / or high-resolution characteristics associated with targets detected at least in part based on those detected in scanning phase 610. That is, relative to the first configuration associated with low-resolution beam 616, the second configuration of high-resolution beam 620 can be used to calculate higher-resolution characteristics associated with targets. Example operating conditions and / or configuration boundaries associated with tracking phase 612 may include tracking CPI with a duration of 5 msec associated with a bandwidth of 0.5 GHz, comb-5 decimation in time (e.g., one in every fifth symbol decimation), and comb-4 decimation in frequency (e.g., one in every fourth resource element (RE) decimation). For a 20 fps update rate associated with the two-stage sensing process, assuming two targets are within the field of view, each user and each detected target can use approximately 4.5% of system resources, and each user can use approximately 9% of system resources. Because two-stage sensing uses less communication overhead compared to single-stage sensing, it may be more suitable for multi-radar sensing that is at least partially based on shared uplink communication resources.

[0090] The expansion of 5G and 6G may include adding sensing processes and / or sensing services, such as adding long-range and / or short-range sensing processes as described above. The coexistence of communication transmissions and radar transmissions in the RAN can lead to various types of interference, such as Rad-Rad interference, Rad-Comm interference, and / or Comm-Comm interference. In some respects, Rad-Rad interference and Rad-Comm interference can affect radar sensing processes in ways different from the impact of Comm-Comm interference on communication processes. For example, radar waveforms may differ in time-frequency grids relative to communication waveforms; radar sensing processes may be more sensitive to bidirectional path loss and receive processing gain relative to communication processes; monostation radar sensing processes may rely on more accurate synchronization relative to communication processes (e.g., information transmission and / or recovery processes); and / or radar interference may reduce the accuracy and / or resolution of radar performance metrics (e.g., velocity accuracy and / or range accuracy) relative to the impact of the communication interface on communication performance metrics (e.g., bit error metrics and / or spectral efficiency metrics). Therefore, interference management techniques used to mitigate the effects of Comm-Comm interference may be ineffective in mitigating Rad-Rad interference and / or Rad-Comm interference, leading to increased errors and / or inaccuracies in radar sensing. Alternatively or additionally, interference management techniques used to mitigate the effects of Comm-Comm interference may be ineffective in mitigating Rad-Comm interference during communication, leading to increased recovery errors, reduced data throughput, and / or increased data transmission delays.

[0091] Some of the technologies and apparatus described herein provide IMC for ICS. The UE can obtain an ICS conflict detection configuration indication that is at least partially based on the interference sensing process. In one example, the UE can obtain the ICS conflict detection configuration indication by receiving it from another UE and / or a network node. In a second example, the UE can obtain the ICS conflict detection configuration indication by generating an ICS conflict detection configuration. The ICS conflict detection configuration indication may specify one or more parameters that can be used to configure the interference sensing process. Therefore, the UE can perform the interference sensing process at least partially based on the ICS conflict detection configuration indication, such as configuring the interface sensing process by using parameters. The UE can send ICS interference messages that are at least partially based on the interference sensing process, such as by sending an ICS measurement report indicating one or more ICS measurement metrics generated by the interference sensing process and / or by sending inter-UE coordination messages indicating auxiliary information that can mitigate interference detected by the interference sensing process.

[0092] A sensing UE (e.g., radar UE 120 and / or communication UE 120) receiving an indication of an ICS conflict detection configuration can mitigate radar-based interference (e.g., Rad-Rad interference and / or Rad-Comm interference) during radar sensing and / or communication processes, as described below. For example, the sensing UE can use the ICS conflict detection configuration to identify air interface resources (such as sidelink air interface resources) associated with potential conflicts between communication and radar transmissions, and avoid using those air interface resources. In some aspects, the sensing UE can forward ICS messages (e.g., IMC measurement reports and / or auxiliary information) to another wireless communication device (e.g., another UE 120 and / or network node 110) indicating air interface resources associated with potential conflicts and / or transmission configurations (e.g., radar transmission configurations). Using the ICS conflict detection configuration and / or ICS messages enables the sensing device and / or the other wireless communication device to mitigate radar-based interference, such as by avoiding the use of air interface resources that may be associated with radar-based interference (e.g., in current transmissions and / or future reservations). Mitigating radar-based interference enables more reliable monostation radar sensing (e.g., increased accuracy) and / or reliable bistation communication (e.g., reduced bit errors, increased data throughput, and / or reduced data transmission latency) in the side link.

[0093] As indicated above, Figure 6 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 6 The examples described are different.

[0094] Figure 7 This is an illustration of example 700 of a wireless communication process between a first UE 702 (e.g., first UE 120) and a second UE 704 (e.g., second UE 120) according to this disclosure. In some aspects, the first UE 702 may be a radar UE including radar sensing capabilities, and the second UE 704 may be a communication UE including communication capabilities. Alternatively or additionally, the first UE 702 may include communication capabilities, and / or the second UE 704 may include radar capabilities.

[0095] As shown by reference numeral 710 in the attached figure, the first UE 702 and the second UE 704 may establish a side link. In some aspects, the side link may use a PC5 interface and / or may operate in a high-frequency band (e.g., the 5.9 GHz band). Additionally or alternatively, the first UE 702 and / or the second UE 704 may use Global Navigation Satellite System (GNSS) timing to synchronize the timing of transmission time intervals (TTIs) (e.g., frames, subframes, time slots, or symbols).

[0096] In some aspects, sidelinks can be based on one or more sidelink channels, such as the Physical Sidelink Control Channel (PSCCH), Physical Sidelink Shared Channel (PSSCH), and / or Physical Sidelink Feedback Channel (PSFCH). The PSCCH can be used to convey control information, similar to the Physical Downlink Control Channel (PDCCH) and / or Physical Uplink Control Channel (PUCCH) used for cellular communication with network node 110 via an access link or access channel. The PSSCH can be used to convey data, similar to the Physical Downlink Shared Channel (PDSCH) and / or Physical Uplink Shared Channel (PUSCH) used for cellular communication with network node 110 via an access link or access channel. For example, the PSCCH can carry sidelink control information (SCI), which can indicate various control information for sidelink communication, such as one or more resources (e.g., time resources, frequency resources, and / or spatial resources), wherein transport blocks (TBs) can be carried on the PSSCH. PSFCH can be used to convey sidelink feedback, such as Hybrid Automatic Repeat Request (HARQ) feedback (e.g., Acknowledgment or Negative Acknowledgment (ACK / NACK) information), Transmit Power Control (TPC), and / or Schedule Request (SR).

[0097] In some aspects, one or more sidelink channels may use resource pools. For example, time-specific resource blocks (RBs) may be used to transmit scheduling assignments in a subchannel (e.g., included in the SCI). In some aspects, data transmissions associated with scheduling assignments (e.g., on the PSSCH) may occupy adjacent RBs in the same subframe as the scheduling assignment (e.g., using frequency division multiplexing). In some aspects, scheduling assignments and associated data transmissions are not transmitted on adjacent RBs.

[0098] In some aspects, the UE (e.g., the first UE 702 and / or the second UE 704) may operate using a sidelink transmission mode (e.g., mode 1), where resource selection and / or scheduling is performed by network node 110 (e.g., a base station, CU, or DU). For example, the UE may receive permission for sidelink channel access and / or scheduling (e.g., in downlink control information (DCI) or in radio resource control (RRC) messages, such as permission for configuration) from network node 110 (e.g., directly or via one or more network nodes). In some aspects, the UE may operate using a transmission mode (e.g., mode 2), where resource selection and / or scheduling is performed by the UE (e.g., not network node 110). In some aspects, the UE may perform resource selection and / or scheduling by sensing the availability of channels for transmission. For example, the UE can measure Received Signal Strength Indicator (RSSI) parameters (e.g., sidelink RSSI (S-RSSI) parameters) associated with various sidelink channels, can measure Reference Signal Received Power (RSRP) parameters (e.g., PSSCH-RSRP parameters) associated with various sidelink channels, and / or can measure Reference Signal Received Quality (RSRQ) parameters (e.g., PSSCH-RSRQ parameters) associated with various sidelink channels, and can select the transmission channel for sidelink communication based at least in part on the measurements.

[0099] As shown by reference numeral 720 in the accompanying drawings, the first UE 702 may obtain an ICS conflict detection configuration, and the ICS conflict detection configuration may indicate one or more parameters that can be used by a UE (e.g., the first UE 702 and / or the second UE 704) to detect and / or predict radar-based interference (e.g., in future time-frequency spatial resources). In some aspects, the first UE 702 may generate the ICS conflict detection configuration. In other aspects, the first UE 702 may receive an ICS conflict detection configuration indication from another device (e.g., the second UE 704, a centralized controller (e.g., a management UE for a group of UEs), and / or network node 110). For illustration, the first UE 702 may be configured to perform a radar sensing process (e.g., a radar UE), and in some aspects, the ICS conflict detection configuration may be at least partially based on the configuration of the radar sensing process. As an example, the ICS conflict detection configuration may include, indicate, and / or be at least partially based on any combination of time-frequency spatial resources, radar UE location, radar UE trajectory, and / or radar transmission parameters.

[0100] In some aspects, the time-frequency space resources indicated by the ICS collision detection configuration may be time-frequency space resources that UE 702 plans to use for radar transmission (and / or may be associated with future time-frequency space resources). The time-frequency space resources may be associated with UEs having Interference Mitigation and Cancellation (IMC) capabilities. That is, the time-frequency space resources may be used by IMC-capable UEs, including IMC capabilities, and the time-frequency space resources may be assigned to and / or classified as resources usable for both radar transmission and communication transmission. Therefore, the first UE 702 may select time-frequency space resources that can be used by UEs with IMC capabilities as time-frequency space resources for detecting and / or predicting interference. In other aspects, the time-frequency space resources indicated by the ICS collision detection configuration may not be associated with UEs with IMC capabilities. For example, the time-frequency space resources may be assigned to legacy UEs that do not have IMC capabilities, may be classified as being used only for radar transmission, and / or may be classified as being used only for communication transmission.

[0101] As shown by reference numeral 730 in the attached figure, the first UE 702 can send an ICS conflict detection configuration instruction, and the second UE 704 can receive an ICS conflict detection configuration instruction. Although Figure 7 An example is illustrated where a first UE 702 sends an ICS collision detection configuration indication to a second UE 704 via a sidelink. However, alternative or additional examples may include the first UE 702 sending an ICS collision detection indication to a network node 110 and / or a centralized controller. By sending the ICS collision detection configuration indication, the UE 702 may notify other wireless communication devices (e.g., the second UE 704, the centralized controller, and / or the network node) of one or more time-frequency space resources to be used in the interference sensing process and / or one or more time-frequency space resources that the first UE 702 plans to use for radar transmission. As described above, the ICS collision detection configuration indication may indicate any combination of time-frequency space resources, radar UE location, radar UE trajectory, and / or radar transmission parameters. Although Figure 7 An example is given of a second UE 704 obtaining an ICS conflict detection configuration by receiving an instruction from a first UE 702, but alternative or additional examples may include the second UE 704 obtaining an ICS conflict detection configuration instruction from a network node 110 and / or a centralized controller.

[0102] As shown by reference numeral 740-1, the first UE 702 may perform an interference sensing process (e.g., a radar interference sensing process and / or a radar interference detection process) that can be used to sense and / or detect interference (e.g., radar interference). Alternatively or additionally, the second UE 704 may perform an interference sensing process (e.g., a radar interference sensing process), as shown by reference numeral 740-2. Therefore, the sensing UE (e.g., the UE performing the interference sensing process) may be a radar UE and / or a communication UE as described above.

[0103] In some aspects, the first UE 702 and / or the second UE 704 may perform the interference sensing process at least in part based on operation in an enabled and / or active interference sensing mode. The enabled and / or active sensing mode may include the sensing UE (e.g., the UE performing the interference sensing process, the first UE 702, and / or the second UE 704) not transmitting signals (e.g., radar transmission and / or communication transmission). Based at least in part on operation in the enabled and / or active sensing mode, the sensing UE may be configured to receive signals and / or calculate interference measurement metrics (e.g., ICS measurement metrics). In some aspects, the sensing UE may be configured to not transmit signals and / or only receive signals when operating in the enabled sensing mode. Prior to operation in the enabled sensing mode, the sensing UE may operate in a disabled and / or inactive sensing mode. The disabled and / or inactive sensing mode may include the UE (e.g., the first UE 702 and / or the second UE 704) transmitting and / or receiving signals (e.g., radar transmission and / or communication transmission) instead of performing the interference sensing process. In some respects, interference sensing processes may not be allowed to be performed in disabled and / or inactive sensing modes.

[0104] As at least part of performing the interference sensing process, the sensing UE may calculate one or more interference measurement metrics (e.g., one or more ICS measurement metrics). As an example of an interference measurement metric, the sensing UE may calculate a received interference power metric, such as by using time-frequency spatial resources indicated by the ICS collision detection configuration. Alternatively or additionally, the sensing UE may calculate the received interference power metric based at least in part on one or more range-angle-Doppler cells. A “range-angle-Doppler cell” may represent a cell and / or sensing area having a specific range metric, a specific angle metric, and / or a specific Doppler metric. Therefore, a set of range-angle-Doppler cells may include cells and / or sensing areas having commensurate (e.g., within a threshold and / or within a range of values) range metrics, commensurate angle metrics, and / or commensurate Doppler metrics. In some aspects, the sensing UE may use one or more cells (and / or one or more sensing areas) to calculate the received interference power metric.

[0105] In some aspects, and as at least part of performing an interference sensing process, the sensing UE may detect the presence and / or absence of interference (e.g., radar interference) at least partially based on a power threshold. For example, the sensing UE may analyze the interference measurement metric generated via the interference sensing process by comparing the interference measurement metric with the power threshold. The sensing UE may detect the presence of interference at least partially based on the interference measurement metric satisfying the power threshold. In some aspects, the power threshold may be at least partially based on one or more factors, such as the UE type associated with the UE (e.g., the sensing UE), the UE's interference capability, the UE's IMC capability, the radar sensing type associated with the UE, and / or the type of IMC capability supported by the UE. For example, the radar UE type may have a different power threshold relative to the communication UE type, at least partially based on how the interference affects the radar process (e.g., radar accuracy) relative to the communication process (e.g., bit error rate). For example, in the presence of interference of a certain amount relative to the bit error rate of the communication process, the accuracy of the radar process may be more significantly affected (e.g., it may become less accurate) (or vice versa). Alternatively or additionally, the first power threshold of a radar UE (e.g., performing a monostation radar sensing procedure) may be higher for targets within the range threshold than a second power threshold associated with a communication UE and / or a second radar UE having targets outside the range threshold, due to better synchronization, higher transmit power, and / or more processing gain. In some aspects, a first sensing UE including IMC capabilities may be more tolerant of a certain amount of interference than a second sensing UE without IMC capabilities. Other examples may include the effectiveness of different radar sensing procedures and / or differences in different types of IMC capabilities. For illustration, a first interference mitigation technique (e.g., a first IMC technique) may include performing interference cancellation after perfect signal reconstruction based at least in part on the UE including communication decoding capabilities, and a second interference mitigation technique (e.g., a second IMC technique) may include zeroing out signals including communication interference (e.g., Comm-Comm interference) in overlapping resources. The first interference mitigation technique may support interference mitigation at a higher interference power level relative to the first interference mitigation technique. Therefore, the power level of a first UE supporting the first interference mitigation technique may be higher than the second power level of a second UE supporting the second interference technique (e.g., and not supporting the first interference technique).

[0106] Alternatively or additionally, as at least part of performing the interference sensing process, the sensing UE may calculate one or more sensing performance metrics. Some non-limiting examples of sensing performance metrics may include range metrics, velocity metrics, angular field of view metrics, sensing resolution metrics, range-velocity-angle domain sensing accuracy metrics, latency and update rate metrics, number of detected targets, intersection-over-union (IoU) metrics associated with target bounding boxes, and / or quality of service (QoS) metrics.

[0107] In some respects, a sensing UE may detect the presence (and / or absence) of interference based at least in part on a quality threshold. For illustration, and in a manner similar to that described above, a sensing UE may compare a calculated sensing performance metric with a quality threshold and / or a detection threshold. A sensing UE may detect the presence of interference based at least in part on a reduction in sensing performance (e.g., accuracy) and / or a reduction in QoS that satisfies a detection threshold.

[0108] The sensing UE (e.g., first UE 702 and / or second UE 704) may perform a single instance and / or multiple instances of an interference process. In some aspects, the sensing UE may perform the interference sensing process periodically and / or using a periodic configuration. That is, the sensing UE may perform the interference sensing process with a specific period and / or using a specific duration (e.g., sampling duration). In some aspects, the periodic configuration may be pre-configured (e.g., set by a communication standard and / or indicated by network node 110). Alternatively or additionally, the periodic configuration may be selected based on one or more operational factors. For example, the periodic configuration of the sensing UE may be based at least in part on any combination of sensing application type, sensing QoS conditions, radar target density, and / or the number of transmitting UEs within a distance threshold (e.g., indicated by channel busy rate (CBR) and / or channel occupancy rate (CR)). In some aspects, the sensing UE may determine the periodic configuration, while in other aspects, another wireless communication device (e.g., network node 110 and / or a centralized controller) may indicate the periodic configuration to the sensing UE. Alternatively or additionally, periodic configurations may be selected and / or coordinated by a group of UEs. For example, periodic configurations may be selected and / or coordinated by a group of UEs to form an interference sensing cluster that can better mitigate interference management compared to individual and / or autonomous interference transmissions by a single UE.

[0109] As indicated by reference numeral 750, a first UE 702 may send a first ICS interference message, and a second UE 704 may receive the first ICS interference message. Alternatively or additionally, as indicated by reference numeral 760, the second UE 704 may send a second ICS interference message, and the first UE 702 may receive the second ICS interference message. In some aspects, the ICS interference message may be and / or include an ICS measurement report indicating one or more interference measurement metrics (e.g., one or more ICS interference measurement metrics) (such as the interference measurement metrics described with reference numerals 740-1 and 740-2).

[0110] Alternatively or additionally, the ICS interference message may be and / or include an inter-UE coordination message indicating auxiliary information. For example, the auxiliary information may provide information about IMC and / or radar transmissions. For illustration, a first UE 702 (e.g., a radar UE) may detect a conflict and / or the presence of a conflict in the time-frequency spatial resources that the first UE 702 plans to use for radar transmissions (e.g., via an interference sensing process as described with respect to reference numeral 740-1). In some aspects, the first UE 702 may send an inter-UE coordination message as an ICS interference message indicating auxiliary information that can be used by the second UE 704 for IMC. As an example, auxiliary information may indicate the waveform type of the radar transmission (e.g., Frequency Modulated Continuous Wave (FMCW), Pulse Modulated Continuous Wave (PMCW), and / or OFDM), specifications of the specific waveform type (such as the chirp slope, bandwidth, and / or carrier frequency for FMCW), transmission power associated with the radar transmission, transmission radiation pattern associated with the radar transmission, and / or radar transmitter location (e.g., front of a vehicle, rear of a vehicle, passenger side of a vehicle, driver side of a vehicle, and / or bumper of a vehicle). In some aspects, the UE transmitting the auxiliary information (e.g., first UE 702 and / or second UE 704) may generate the auxiliary information. Alternatively or additionally, inter-UE coordination messages may include auxiliary information from multiple wireless communication devices. For example, first UE 702 may generate first auxiliary information associated with a first radar transmission and / or may receive second auxiliary information associated with a second radar transmission from another wireless communication device (e.g., third UE 120, another radar UE, and / or another communication UE). In some aspects, the first UE 702 may indicate first auxiliary information and second auxiliary information in an inter-UE coordination message. Alternatively or additionally, the second auxiliary information may include information that can be used by the communicating UE, such as arrival time measures that enable the communicating UE to mitigate synchronization errors and / or timing errors.

[0111] The auxiliary information may be based at least in part on a subset of interference measurement metrics. For illustration, and as described with respect to reference numerals 740-1 and 740-2, a sensing UE (e.g., a first UE 702 and / or a second UE 704) may calculate multiple interference measurement metrics, and a transmitting UE may use a subset of interference measurement metrics included in the multiple interference measurement metrics to generate auxiliary information. For example, as at least part of the interference sensing process, the sensing UE may calculate a corresponding conflict metric (e.g., conflict probability and / or conflict detection) for each of the multiple interference measurement metrics, and may use multiple conflict metrics to select a subset of interference metrics. For illustration, the sensing UE may generate a conflict metric for each time slot transmitted by a five-slot radar, indicating whether the sensing UE has detected interference in the corresponding time slot. Thus, the sensing UE may generate five conflict metrics. In some aspects, the sensing UE may include only information associated with the detection of a conflict in the auxiliary information. For example, the sensing UE may detect a potential conflict for a second of the five time slots (e.g., via a corresponding conflict metric) and / or may not detect a potential conflict in the other four time slots. Therefore, the sensing UE can indicate relevant auxiliary information (e.g., a subset of information) indicating potential conflicts (e.g., auxiliary information only about the second time slot).

[0112] Alternatively or additionally, auxiliary information may include transmission information. For example, auxiliary information may include first transmission information that a radar UE can use to transmit radar transmissions and / or second transmission information (e.g., timing advance information) that a communication UE can use to transmit communications, as described above. In some aspects, the transmission information may include security information such as a Radio Network Temporary Identifier (RNTI), a scrambling sequence, a security key, and / or an initial seed that can be used to encode and / or recover encrypted information. A receiving UE (e.g., a receiving communication UE) may use the security information to perform soft cancellation interference mitigation and / or process high-priority communications. Alternatively or additionally, the security key and / or the initial seed may be used by a transmitting UE (e.g., a transmitting communication UE) to use the same time-frequency space resources for communication transmissions, such as for transmitting high-priority communications. In some aspects, the identifier (ID) used for transmission may be a default ID and / or a public ID known to multiple UEs and / or wireless communication devices.

[0113] As indicated by reference numeral 770 in the accompanying drawings, the first UE 702 may perform a radar sensing process, such as by transmitting radar transmissions and / or processing received echoes as described above. In some aspects, the first UE 702 may use information indicated by one or more ICS interference messages to perform the radar sensing process. For example, the first UE 702 may generate radar transmissions at least in part based on the use of waveform type, transmission power level, and / or time-frequency space resources. As another example, the first UE 702 may avoid using time-frequency space resources, such as those that may overlap with communication transmissions.

[0114] As indicated by reference numeral 780 in the accompanying drawings, the second UE 704 may perform communication procedures, such as by transmitting and / or receiving communications (e.g., sidelink communications and / or access link communications). In some aspects, the first UE 702 may perform communication procedures using information indicated by one or more ICS interference messages. For example, the first UE 702 may transmit communications by avoiding the use of time-frequency space resources indicated by ICS interface messages (such as time-frequency space resources indicated to include interference). Alternatively or additionally, the first UE 702 may use transmission information to generate communications and / or perform soft cancellation as described above.

[0115] A sensing UE that receives an indication of ICS collision detection configuration can mitigate radar-based interference during radar sensing and / or communication processes. For example, the sensing UE can use the ICS collision detection configuration to identify air interface resources (such as sidelink air interface resources) associated with potential collisions between communication transmissions and radar transmissions, and avoid using those air interface resources. In some aspects, the sensing UE can forward ICS messages to another wireless communication device, indicating air interface resources associated with potential collisions and / or transmission configurations. Mitigating radar-based interference can enable more reliable monostation radar sensing (e.g., increased accuracy) and / or more reliable bistation communication in the sidelink (e.g., reduced bit errors, increased data throughput, and / or reduced data transmission latency).

[0116] As indicated above, Figure 7 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 7 The examples described are different.

[0117] Figure 8 This is a diagram illustrating an example process 800 performed, for example, at a UE or a device of a UE, according to this disclosure. Example process 800 is an example in which a device or UE (e.g., UE 120) performs operations associated with an ICS having an IMC.

[0118] like Figure 8As shown, in some aspects, process 800 may include obtaining an ICS conflict detection configuration indication associated with the interference sensing process (block 810). For example, the UE (e.g., using...) Figure 9 The receiving component 902 and / or communication manager 906 depicted herein may obtain ICS collision detection configuration instructions, at least in part, based on the interference sensing process, as described above. For illustration, the UE may obtain, as per [the description of the ICS collision detection configuration instructions]... Figure 7 The attached figure 720 describes the ICS conflict detection configuration.

[0119] like Figure 8 As further shown, in some aspects, process 800 may include performing an interference sensing process (block 820) using an ICS conflict detection configuration indication. For example, the UE (e.g., using...)

For illustration, the UE can perform actions such as regarding... Figure 7 The interference sensing process is described by reference numerals 740-1 and / or 740-2.

[0120] like Figure 8 As further shown, in some aspects, process 800 may include sending an ICS interference message (box 830) that is at least partially based on the interference sensing process. For example, the UE (e.g., using...) Figure 9 The transmitting component 904 and / or communication manager 906 depicted above can transmit ICS interference messages based at least in part on the interference sensing process. For illustration, the UE can transmit messages such as those related to... Figure 7 The ICS interference messages described by reference numerals 750 and / or 760.

[0121] Process 800 may include additional aspects, such as any single aspect or any combination of aspects described below and / or in conjunction with one or more other processes described elsewhere herein.

[0122] In the first aspect, the ICS conflict detection configuration indication indicates at least one of time-frequency space resources, radar UE location, radar UE trajectory, or radar transmission parameters.

[0123] In the second aspect, the time-frequency spatial resources are associated with a UE having IMC capabilities, which include IMC capabilities associated with radar transmission and communication transmission.

[0126] In the fifth aspect, process 800 includes sending an ICS collision detection configuration instruction to a wireless communication device in a wireless network.

[0127] In the sixth aspect, the UE is a communication UE, and obtaining the ICS conflict detection configuration indication includes receiving the ICS conflict detection configuration indication from the radar UE.
