INTEGRATED COMMUNICATIONS AND SENSING WITHINTERFERENCE MITIGATION AND CANCELLATIONCROSS-REFERENCE TO RELATED APPLICATION

[0001] 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 hereby expressly incorporated by reference herein.FIELD OF THE DISCLOSURE

[0002] Aspects of the present disclosure generally relate to wireless communication and to techniques and apparatuses for integrated communications and sensing with interference mitigation and cancellation.BACKGROUND

[0003] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasts. Typical wireless communication systems may employ multiple-access technologies capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, or the like). Examples of such multiple-access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single -carrier frequency division multiple access (SC- FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and Long Term Evolution (LTE). LTE / LTE- Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP).

[0004] A wireless network may include one or more network nodes that support communication for wireless communication devices, such as a user equipment (UE) or multiple UEs. A UE may communicate with a network node via downlink communications and uplink communications. “Downlink” (or “DL”) refers to a communication link from the network node to the UE, and “uplink” (or “UL”) refers to a communication link from the UE to the network node. Some wireless networks may support device-to-device communication, such as via a local link (e.g., a sidelink (SL), a wireless local area network (WLAN) link, and / or a wireless personal area network (WPAN) link, among other examples).

[0005] The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different UEs tocommunicate on a municipal, national, regional, and / or global level. New Radio (NR), which may be referred to as 5G, is a set of enhancements to the LTE mobile standard promulgated by the 3GPP. NR is designed to better support mobile broadband internet access by improving spectral efficiency, lowering costs, improving services, making use of new spectrum, and better integrating with other open standards using orthogonal frequency division multiplexing (OFDM) with a cyclic prefix (CP) (CP-OFDM) on the downlink, using CP-OFDM and / or single-carrier frequency division multiplexing (SC-FDM) (also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink, as well as supporting beamforming, multiple-input multiple -output (MIMO) antenna technology, and carrier aggregation. As the demand for mobile broadband access continues to increase, further improvements in LTE, NR, and other radio access technologies remain useful.SUMMARY

[0006] Some aspects described herein relate to a method of wireless communication performed by a user equipment (UE). The method may include obtaining an integrated communication and sensing (ICS) collision detection configuration indication that is associated with an interference sensing procedure.

[0024] The expansion of next generation (NG) radio access technologies (RATs), such as fifth-generation (5G) (also referred to as New Radio (NR)) and / or sixth-generation (6G), may include the addition of sensing procedures and / or sensing services in combination with communication services. Example sensing services may include a long-range radar (e.g., radiodetection and ranging) sensing procedure configured to sense objects that are more than 250 meters away and / or a short-range radar sensing procedure configured to objects that are less than 50 meters away. The co-existence of communication transmissions and radar transmissions in a radio access network (RAN) may result in multiple types of interference. Some non-limiting examples may include radar-to-radar (Rad-Rad) interference, radar-to- communication (Rad-Comm) interference, and / or communication-to-communication (Comm- Comm) interference. In some aspects, Rad-Rad interference and Rad-Comm interference may affect a radar sensing procedure in a different manner than the effects of Comm-Comm interference on communication procedures (e.g., modulation, encoding, transmission, reception, demodulation, and / or decoding). Accordingly, interference management techniques used to mitigate the effects of Comm-Comm interference may be ineffective for mitigating the effects of Rad-Rad interference and / or Rad-Comm interference in a radar sensing procedure, and may result in increased errors and / or increased inaccuracies in the radar sensing procedure. Alternatively, or additionally, the interference management techniques used to mitigate the effects of Comm-Comm interference may be ineffective for mitigating the effects of Rad-Comm interference in a communication procedure, and may result in increased recovery errors, reduced data throughput, and / or increased data transfer latencies in a wireless network.

[0025] Various aspects described herein generally relate to integrated communications and sensing (ICS) with interference mitigation and cancellation (IMC). Some aspects relate more specifically to a sensing UE performing a sensing procedure using an ICS collision detection configuration. A UE may obtain an ICS collision detection configuration indication that is associated with an interference sensing procedure. In one example, the UE may obtain the ICS collision detection configuration indication by receiving the ICS collision detection configuration indication from another UE and / or a network node. In a second example, the UE may obtain the ICS collision detection configuration indication by generating the ICS collision detection configuration. The ICS collision detection configuration indication may specify one or more parameters that may be used to configure the interference sensing procedure. Accordingly, the UE may perform the interference sensing procedure based at least in part on using the ICS collision detection configuration indication, such as by configuring the interface sensing procedure using the parameter(s). The UE may transmit an ICS interference message that is based at least in part on the interference sensing procedure, such as by transmitting an ICS measurement report that indicates one or more ICS measurement metrics generated by the interference sensing procedure and / or by transmitting an inter-UE coordination message that indicates assistance information that may mitigate interference detected by the interference sensing procedure.

[0026] A sensing UE receiving an indication of an ICS collision detection configuration may mitigate radar-based interference (e.g., Rad-Rad interference and / or Rad-Comm interference) ina radar sensing procedure and / or a communication procedure as described below. For example, the sensing UE may use the ICS collision detection configuration to identify an air interface resource that is associated with a potential collision between a communication transmission and a radar transmission, such as a sidelink air interface resource, and avoid use of the air interface resource. Alternatively, or additionally, the sensing UE may forward an ICS message that indicates the air interface resource that is associated with the potential collision and / or a transmission configuration (e.g., a radar transmission configuration) to enable other devices to avoid use of the air interface resource. The use of an ICS collision detection configuration and / or an ICS message may enable the sensing device and / or the other wireless communication device to mitigate radar-based interference, resulting in reliable monostatic radar sensing and / or bistatic communication in a sidelink. To illustrate, mitigating the radar-based interference may increase a radar sensing accuracy of the monostatic radar sensing, reduce bit errors in the bistatic communication, increase data throughput in the bistatic communication, and / or reduce data transfer latencies in the bistatic communication.

[0027] Various aspects of the disclosure are described more fully hereinafter with reference to the accompanying drawings. This disclosure may, however, be embodied in many different forms and should not be construed as limited to any specific structure or function presented throughout this disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. One skilled in the art should appreciate that the scope of the disclosure is intended to cover any aspect of the disclosure disclosed herein, whether implemented independently of or combined with any other aspect of the disclosure. For example, an apparatus may be implemented or a method may be practiced using any number of the aspects set forth herein. In addition, the scope of the disclosure is intended to cover such an apparatus or method which is practiced using other structure, functionality, or structure and functionality in addition to or other than the various aspects of the disclosure set forth herein. It should be understood that any aspect of the disclosure disclosed herein may be embodied by one or more elements of a claim.

[0028] Several aspects of telecommunication systems will now be presented with reference to various apparatuses and techniques. These apparatuses and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, or the like (collectively referred to as “elements”). These elements may be implemented using hardware, software, or combinations thereof. Whether such elements are implemented as hardware or software depends upon the particular application and design constraints imposed on the overall system.

[0029] While aspects may be described herein using terminology commonly associated with a 5G or New Radio (NR) radio access technology (RAT), aspects of the present disclosure canbe applied to other RATs, such as a 3G RAT, a 4G RAT, and / or a RAT subsequent to 5G (e.g., 6G).

[0030] Fig. 1 is a diagram illustrating an example of a wireless network 100, in accordance with the present disclosure. The wireless network 100 may be or may include elements of a 5G (e.g., NR) network and / or a 4G (e.g., Long Term Evolution (LTE)) network, among other examples. The wireless network 100 may include one or more network nodes 110 (shown as a network node 110a, a network node 110b, a network node 110c, and a network node 1 lOd), a UE 120 or multiple UEs 120 (shown as a UE 120a, a UE 120b, a UE 120c, a UE 120d, and a UE 120e), and / or other entities. A network node 110 is a network node that communicates with UEs 120. As shown, a network node 110 may include one or more network nodes. For example, a network node 110 may be an aggregated network node, meaning that the 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, a network node 110 may be a disaggregated network node (sometimes referred to as a disaggregated base station), meaning that the 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)).

[0031] In some examples, a network node 110 is or includes a network node that communicates with UEs 120 via a radio access link, such as an RU. In some examples, a network node 110 is or includes a network node that communicates with other network nodes 110 via a fronthaul link or a midhaul link, such as a DU. In some examples, a network node 110 is or includes a network node that communicates with other network nodes 110 via a midhaul link or a core network via a backhaul link, such as a CU. In some examples, a network node 110 (such as an aggregated network node 110 or a disaggregated network node 110) may include multiple network nodes, such as one or more RUs, one or more CUs, and / or one or more DUs. A network node 110 may include, for example, an NR base station, an LTE base station, a Node B, an eNB (e.g., in 4G), a gNB (e.g., in 5G), an access point, a transmission reception point (TRP), a DU, an RU, a CU, a mobility element of a network, a core network node, a network element, a network equipment, a RAN node, or a combination thereof. In some examples, the network nodes 110 may be interconnected to one another or to one or more other network nodes 110 in the wireless network 100 through various types of fronthaul, midhaul, and / or backhaul interfaces, such as a direct physical connection, an air interface, or a virtual network, using any suitable transport network.

[0032] In some examples, a network node 110 may provide communication coverage for a particular geographic area. In the Third Generation Partnership Project (3GPP), the term “cell” can refer to a coverage area of a network node 110 and / or a network node subsystem servingthis coverage area, depending on the context in which the term is used. A network node 110 may provide communication coverage for a macro cell, a pico cell, a femto cell, and / or another type of cell. A macro cell may cover a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by UEs 120 with service subscriptions. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs 120 with service subscriptions. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by UEs 120 having association with the femto cell (e.g., UEs 120 in a closed subscriber group (CSG)). A network node 110 for a macro cell may be referred to as a macro network node. A network node 110 for a pico cell may be referred to as a pico network node. A network node 110 for a femto cell may be referred to as a femto network node or an in-home network node. In the example shown in Fig. 1, the network node 110a may be a macro network node for a macro cell 102a, the network node 110b may be a pico network node for a pico cell 102b, and the network node 110c may be a femto network node for a femto cell 102c. A network node may support one or multiple (e.g., three) cells. In some examples, a cell may not necessarily be stationary, and the geographic area of the cell may move according to the location of a network node 110 that is mobile (e.g., a mobile network node).

[0033] In some aspects, the terms “base station” or “network node” may refer to an aggregated base station, a disaggregated 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, a DU, an 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 terms “base station” or “network node” may refer to one device configured to perform one or more functions, such as those described herein in connection with the network node 110. In some aspects, the terms “base station” or “network node” may refer to a plurality of devices configured to perform the one or more functions. For example, in some distributed systems, each of a quantity of different devices (which may be located in the same geographic location or in different geographic locations) may be configured to perform at least a portion of a function, or to duplicate performance of at least a portion of the function, and the terms “base station” or “network node” may refer to any one or more of those different devices. In some aspects, the terms “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 may be instantiated on a single device. In some aspects, the terms “base station” or “network node” may refer to one of the base station functions and not another. In this way, a single device may include more than one base station.

[0034] The wireless network 100 may include one or more relay stations. A relay station is a network node that can receive a transmission of data from an upstream node (e.g., a network node 110 or a UE 120) and send a transmission of the data to a downstream node (e.g., a UE120 or a network node 110). A relay station may be a UE 120 that can relay transmissions for other UEs 120. In the example shown in Fig. 1, the network node 1 lOd (e.g., a relay network node) may communicate with the network node 110a (e.g., a macro network node) and the UE 120d in order to facilitate communication between the network node 110a and the UE 120d. A network node 110 that relays communications may be referred to as a relay station, a relay base station, a relay network node, a relay node, a relay, or the like.

[0035] The wireless network 100 may be a heterogeneous network that includes network nodes 110 of different types, such as macro network nodes, pico network nodes, femto network nodes, relay network nodes, or the like. These different types of network nodes 110 may have different transmit power levels, different coverage areas, and / or different impacts on interference in the wireless network 100. For example, macro network nodes may have a high transmit power level (e.g., 5 to 40 watts) whereas pico network nodes, femto network nodes, and relay network nodes may have lower transmit power levels (e.g., 0.1 to 2 watts).

[0036] A network controller 130 may couple to or communicate with a set of network nodes 110 and may provide coordination and control for these network nodes 110. The network controller 130 may communicate with the network nodes 110 via a backhaul communication link or a midhaul communication link. The network nodes 110 may communicate with one another directly or indirectly via a wireless or wireline backhaul communication link. In some aspects, the network controller 130 may be a CU or a core network device, or may include a CU or a core network device.

[0037] The UEs 120 may be dispersed throughout the wireless network 100, and each UE 120 may be stationary or mobile. A UE 120 may include, for example, an access terminal, a terminal, a mobile station, and / or a subscriber unit. A UE 120 may be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device, a biometric device, a wearable device (e.g., a smart watch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring or a smart bracelet)), an entertainment device (e.g., a music device, a video device, and / or a satellite radio), a vehicular component or sensor, a smart meter / sensor, industrial manufacturing equipment, a global positioning system device, a UE function of a network node, and / or any other suitable device that is configured to communicate via a wireless or wired medium.

[0038] Some UEs 120 may be considered machine-type communication (MTC) or evolved or enhanced machine-type communication (eMTC) UEs. An MTC UE and / or an eMTC UE may include, for example, a robot, an unmanned aerial vehicle, a remote device, a sensor, a meter, a monitor, and / or a location tag, that may communicate with a network node, another device (e.g., a remote device), or some other entity. Some UEs 120 may be considered Intemet-of-Things(loT) devices, and / or may be implemented as NB-IoT (narrowband loT) devices. Some UEs 120 may be considered a Customer Premises Equipment. A UE 120 may be included inside a housing that houses components of the UE 120, such as processor components and / or memory components. In some examples, the processor components and the memory components may be coupled together. For example, the processor components (e.g., one or more processors) and the memory components (e.g., a memory) may be operatively coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0039] In general, any number of wireless networks 100 may be deployed in a given geographic area. Each wireless network 100 may support a particular RAT and may operate on one or more frequencies. A RAT may be referred to as a radio technology, an air interface, or the like. A frequency may be referred to as a carrier, a frequency channel, or the like. Each frequency may support a single RAT in a given geographic area in order to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed.

[0040] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more side link channels (e.g., without using a network node 110 as an intermediary to communicate with one another). For example, the UEs 120 may communicate using peer-to-peer (P2P) communications, device-to-device (D2D) communications, a vehicle-to-everything (V2X) protocol (e.g., which may include a vehicle-to- vehicle (V2V) protocol, a vehicle -to-infrastructure (V2I) protocol, or a vehicle-to-pedestrian (V2P) protocol), and / or a mesh network. In such examples, a UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by the network node 110.

[0041] Devices of the wireless network 100 may communicate using the electromagnetic spectrum, which may be subdivided by frequency or wavelength into various classes, bands, channels, or the like. For example, devices of the wireless network 100 may communicate using one or more operating bands. In 5G NR, two initial operating bands have been identified as frequency range designations FR1 (410 MHz - 7.125 GHz) and FR2 (24.25 GHz - 52.6 GHz). It should be understood that although a portion of FR1 is greater than 6 GHz, FR1 is often referred to (interchangeably) as a “Sub-6 GHz” band in various documents and articles. A similar nomenclature issue sometimes occurs with regard to FR2, which is often referred to (interchangeably) as a “millimeter wave” band in documents and articles, despite being different from the extremely high frequency (EHF) band (30 GHz - 300 GHz) which is identified by the International Telecommunications Union (ITU) as a “millimeter wave” band.

[0042] The frequencies between FR1 and FR2 are often referred to as mid-band frequencies. Recent 5G NR studies have identified an operating band for these mid-band frequencies as frequency range designation FR3 (7.125 GHz - 24.25 GHz). Frequency bands falling withinFR3 may inherit FR1 characteristics and / or FR2 characteristics, and thus may effectively extend features of FR1 and / or FR2 into mid-band frequencies. In addition, higher frequency bands are currently being explored to extend 5G NR operation beyond 52.6 GHz. For example, three higher operating bands have been identified as frequency range designations FR4a or FR4-1 (52.6 GHz - 71 GHz), FR4 (52.6 GHz - 114.25 GHz), and FR5 (114.25 GHz - 300 GHz).Each of these higher frequency bands falls within the EHF band.

[0043] With the above examples in mind, unless specifically stated otherwise, it should be understood that the term “sub-6 GHz” or the like, if used herein, may broadly represent frequencies that may be less than 6 GHz, may be within FR1, or may include mid-band frequencies. Further, unless specifically stated otherwise, it should be understood that the term “millimeter wave” or the like, if used herein, may broadly represent frequencies that may include mid-band frequencies, may be within FR2, FR4, FR4-a or FR4-1, and / or FR5, or may be within the EHF band. It is contemplated that the frequencies included in these operating bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, and / or FR5) may be modified, and techniques described herein are applicable to those modified frequency ranges.

[0044] In some aspects, a UE (e.g., a UE 120) may include a communication manager 140. As described in more detail elsewhere herein, the communication manager 140 may obtain an ICS collision detection configuration indication that is associated with an interference sensing procedure; perform the interference sensing procedure using the ICS collision detection configuration indication; and transmit an ICS interference message that is 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.

[0045] As indicated above, Fig. 1 is provided as an example. Other examples may differ from what is described with regard to Fig. 1.

[0046] Fig. 2 is a diagram illustrating an example 200 of a network node 110 in communication with a UE 120 in a wireless network 100, in accordance with the present disclosure. The network node 110 may be equipped with a set of antennas 234a through 234t, such as T antennas (T> 1). The UE 120 may be equipped with a set of antennas 252a through 252r, such as R antennas (R > 1). The network node 110 of example 200 includes one or more radio frequency components, such as antennas 234 and a modem 232. In some examples, a network node 110 may include an interface, a communication component, or another component that facilitates communication with the UE 120 or another network node. Some network nodes 110 may not include radio frequency components that facilitate direct communication with the UE 120, such as one or more CUs, or one or more DUs.

[0047] At the network node 110, a transmit processor 220 may receive data, from a data source 212, intended for the UE 120 (or a set of UEs 120). The transmit processor 220 mayselect one or more modulation and coding schemes (MCSs) for the UE 120 based at least in part on one or more channel quality indicators (CQIs) received from that UE 120. The network node 110 may process (e.g., encode and modulate) the data for the UE 120 based at least in part on the MCS(s) selected for the UE 120 and may provide data symbols for the UE 120. The transmit processor 220 may process system information (e.g., for semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper layer signaling) and provide overhead symbols and control symbols. The transmit processor 220 may generate reference symbols for reference signals (e.g., a cell-specific reference signal (CRS) or a demodulation reference signal (DMRS)) and synchronization signals (e.g., a primary synchronization signal (PSS) or a secondary synchronization signal (SSS)). A transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on the data symbols, the control symbols, the overhead symbols, and / or the reference symbols, if applicable, and may 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 through 232t. For example, each output symbol stream may be provided to a modulator component (shown as MOD) of a modem 232. Each modem 232 may use a respective modulator component to process a respective output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modem 232 may further use a respective modulator component to process (e.g., convert to analog, amplify, fdter, and / or upconvert) the output sample stream to obtain a downlink signal. The modems 232a through 232t may 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 through 234t.

[0048] At the UE 120, a set of antennas 252 (shown as antennas 252a through 252r) may receive the downlink signals from the network node 110 and / or other network nodes 110 and may provide a set of received signals (e.g., R received signals) to a set of modems 254 (e.g., R modems), shown as modems 254a through 254r. For example, each received signal may be provided to a demodulator component (shown as DEMOD) of a modem 254. Each modem 254 may use a respective demodulator component to condition (e.g., filter, amplify, downconvert, and / or digitize) a received signal to obtain input samples. Each modem 254 may use a demodulator component to further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector 256 may obtain received symbols from the modems 254, may perform MIMO detection on the received symbols if applicable, and may provide detected symbols. A receive processor 258 may process (e.g., demodulate and decode) the detected symbols, may provide decoded data for the UE 120 to a data sink 260, and may provide decoded control information and system information to a controller / processor 280. The term “controller / processor” may refer to one or more controllers, one or more processors, or a combination thereof. A channel processor may determine a reference signal received power(RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, and / or a CQI parameter, among other examples. In some examples, one or more components of the UE 120 may be included in a housing 284.

[0049] The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292. The network controller 130 may include, for example, one or more devices in a core network. The network controller 130 may communicate with the network node 110 via the communication unit 294.

[0050] One or more antennas (e.g., antennas 234a through 234t and / or antennas 252a through 252r) may include, 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, among other examples. An antenna panel, an antenna group, a set of antenna elements, and / or an antenna array may include one or more antenna elements (within a single housing or multiple housings), a set of coplanar antenna elements, a set of non-coplanar antenna elements, and / or one or more antenna elements coupled to one or more transmission and / or reception components, such as one or more components of Fig. 2.

[0051] On the uplink, at the UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information (e.g., for reports that include RSRP, RSSI, RSRQ, and / or CQI) from the controller / processor 280. The transmit processor 264 may generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be precoded by a TX MIMO processor 266 if applicable, further processed by the modems 254 (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to the network node 110. In some examples, the modem 254 of the UE 120 may include a modulator and a demodulator. In some examples, the UE 120 includes a transceiver. The transceiver may include any combination of the antenna(s) 252, the modem(s) 254, the MIMO detector 256, the receive processor 258, the transmit processor 264, and / or the TX MIMO processor 266. The transceiver may be used by a processor (e.g., the controller / processor 280) and the memory 282 to perform aspects of any of the methods described herein (e.g., with reference to Figs. 6-9).

[0052] At the network node 110, the uplink signals from UE 120 and / or other UEs may be received by the antennas 234, processed by the modem 232 (e.g., a demodulator component, shown as DEMOD, of the modem 232), detected by a MIMO detector 236 if applicable, and further processed by a receive processor 238 to obtain decoded data and control information sent by the UE 120. The receive processor 238 may provide the decoded data to a data sink 239 and provide the decoded control information to the controller / processor 240. The network node 110 may include a communication unit 244 and may communicate with the network controller 130 via the communication unit 244. The network node 110 may include a scheduler 246 to schedule one or more UEs 120 for downlink and / or uplink communications. In some examples, the modem 232 of the network node 110 may include a modulator and a demodulator. In someexamples, the network node 110 includes a transceiver. The transceiver may include any combination of the antenna(s) 234, the modem(s) 232, the MIMO detector 236, the receive processor 238, the transmit processor 220, and / or the TX MIMO processor 230. The transceiver may be used by a processor (e.g., the controller / processor 240) and the memory 242 to perform aspects of any of the methods described herein (e.g., with reference to Figs. 6-9.

[0053] The controller / processor 240 of the network node 110, the controller / processor 280 of the UE 120, and / or any other component(s) of Fig. 2 may perform one or more techniques associated with ICS with IMC, as described in more detail elsewhere herein. For example, the controller / processor 240 of the network node 110, the controller / processor 280 of the UE 120, and / or any other component(s) of Fig. 2 may perform or direct operations of, for example, process 800 of Fig. 8, and / or other processes as described herein. The memory 242 and the memory 282 may store data and program codes for the network node 110 and the UE 120, respectively. In some examples, the memory 242 and / or the memory 282 may include a non- transitory computer-readable medium storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, the one or more instructions, when executed (e.g., directly, or after compiling, converting, and / or interpreting) by one or more processors of the network node 110 and / or the UE 120, may cause the one or more processors, the UE 120, and / or the network node 110 to perform or direct operations of, for example, process 800 of Fig. 8, and / or other processes as described herein. In some examples, executing instructions may include running the instructions, converting the instructions, compiling the instructions, and / or interpreting the instructions, among other examples.

[0054] In some aspects, a UE (e.g., a UE 120) includes means for obtaining an ICS collision detection configuration indication that is based at least in part on an interference sensing procedure; means for performing the interference sensing procedure using the ICS collision detection configuration indication; and / or means for transmitting an ICS interference message that is based at least in part on the interference sensing procedure. The means for the UE to perform operations described herein may include, for example, one or more of communication manager 140, antenna 252, modem 254, MIMO detector 256, receive processor 258, transmit processor 264, TX MIMO processor 266, controller / processor 280, or memory 282.

[0055] In some aspects, an individual processor may perform all of the functions described as being performed by the one or more processors. In some aspects, one or more processors may collectively perform a set of functions. For example, a first set of (one or more) processors of the one or more processors may perform a first function described as being performed by the one or more processors, and a second set of (one or more) processors of the one or more processors may perform a second function described as being performed by the one or more processors. The first set of processors and the second set of processors may be the same set of processors or may be different sets of processors. Reference to “one or more processors” shouldbe understood to refer to any one or more of the processors described in connection with Fig. 2. Reference to “one or more memories” should be understood to refer to any one or more memories of a corresponding device, such as the memory described in connection with Fig.2. For example, functions described as being performed by one or more memories can be performed by the same subset of the one or more memories or different subsets of the one or more memories.

[0056] While blocks in Fig. 2 are illustrated as distinct components, the functions described above with respect to the blocks may be implemented in a single hardware, software, or combination component or in various combinations of components. For example, the functions described with respect to the transmit processor 264, the receive processor 258, and / or the TX MIMO processor 266 may be performed by or under the control of the controller / processor 280.

[0057] As indicated above, Fig. 2 is provided as an example. Other examples may differ from what is described with regard to Fig. 2.

[0058] Deployment of communication systems, such as 5G NR systems, may be arranged in multiple manners with various components or constituent parts. In a 5G NR system, or network, a network node, a network entity, a mobility element of a network, a RAN node, a core network node, a network element, a base station, or a network equipment may be implemented in an aggregated or disaggregated architecture. For example, a base station (such as a Node B (NB), an evolved NB (eNB), an NR base station, a 5G NB, an access point (AP), a TRP, or a cell, among other examples), or one or more units (or one or more components) performing base station functionality, may be implemented as an aggregated base station (also known as a standalone base station or a monolithic base station) or a disaggregated base station. “Network entity” or “network node” may refer to a disaggregated base station, or to one or more units of a disaggregated base station (such as one or more CUs, one or more DUs, one or more RUs, or a combination thereof).

[0059] An aggregated base station (e.g., an aggregated network node) may 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 unit). A disaggregated base station (e.g., a disaggregated network node) may be configured to utilize a protocol stack that is physically or logically distributed among two or more units (such as one or more CUs, one or more DUs, or one or more RUs). In some examples, a 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 throughout one or multiple other network nodes. The DUs may be implemented to communicate with one or more RUs. Each of the CU, DU, and RU also can be implemented as virtual units, such as a virtual central unit (VCU), a virtual distributed unit (VDU), or a virtual radio unit (VRU), among other examples.

[0060] Base station-type operation or network design may consider aggregation characteristics of base station functionality. For example, disaggregated base stations may be utilized in an IAB network, an open radio access network (0-RAN (such as the network configuration sponsored by the 0-RAN Alliance)), or a virtualized radio access network (vRAN, also known as a cloud radio access network (C-RAN)) to facilitate scaling of communication systems by separating base station functionality into one or more units that can be individually deployed. A disaggregated base station may include functionality implemented across two or more units at various physical locations, as well as functionality implemented for at least one unit virtually, which can enable flexibility in network design. The various units of the disaggregated base station can be configured for wired or wireless communication with at least one other unit of the disaggregated base station.

[0061] Fig. 3 is a diagram illustrating an example disaggregated base station architecture 300, in accordance with the present disclosure. The disaggregated base station architecture 300 may include a CU 310 that can communicate directly with a core network 320 via a backhaul link, or indirectly with the core network 320 through one or more disaggregated control units (such as a 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). A CU 310 may communicate with one or more DUs 330 via respective midhaul links, such as through Fl interfaces. Each of the DUs 330 may communicate with one or more RUs 340 via respective fronthaul links. Each of the RUs 340 may communicate with one or more UEs 120 via respective radio frequency (RF) access links. In some implementations, a UE 120 may be simultaneously served by multiple RUs 340.

[0062] Each of the units, including the CUs 310, the DUs 330, the RUs 340, as well as the Near-RT RICs 325, the Non-RT RICs 315, and the SMO Framework 305, may include one or more interfaces or be coupled with one or more interfaces configured to receive or transmit signals, data, or information (collectively, signals) via a wired or wireless transmission medium. Each of the units, or an associated processor or controller providing instructions to one or multiple communication interfaces of the respective unit, can be configured to communicate with one or more of the other units via the transmission medium. In some examples, each of the units can include a wired interface, configured to receive or transmit signals over a wired transmission medium to one or more of the other units, and a wireless interface, which may include a receiver, a transmitter or transceiver (such as an RF transceiver), configured to receive or transmit signals, or both, over a wireless transmission medium to one or more of the other units.

[0063] In some aspects, the CU 310 may host one or more higher layer control functions. Such control functions can include radio resource control (RRC) functions, packet data convergence protocol (PDCP) functions, or service data adaptation protocol (SDAP) functions,among other examples. Each control function can be implemented with an interface configured to communicate signals with other control functions hosted by the CU 310. The CU 310 may be configured to handle user plane functionality (for example, Central Unit - User Plane (CU-UP) functionality), control plane functionality (for example, Central Unit - Control Plane (CU-CP) functionality), or a combination 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. A CU-UP unit can communicate bidirectionally with a CU-CP unit via an interface, such as the El interface when implemented in an O-RAN configuration. The CU 310 can be implemented to communicate with a DU 330, as necessary, for network control and signaling.

[0064] Each DU 330 may correspond to a logical unit that includes one or more base station functions to control the operation of one or more RUs 340. In some aspects, the DU 330 may host one or more of a radio link control (RLC) layer, a medium access control (MAC) layer, and one or more high physical (PHY) layers depending, at least in part, on a functional split, such as a functional split defined by the 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, among other examples. In some aspects, the DU 330 may further host one or more low PHY layers, such as implemented by one or more modules for a fast Fourier transform (FFT), an inverse FFT (iFFT), digital beamforming, or physical random access channel (PRACH) extraction and filtering, among other examples. Each layer (which also may be referred to as a module) can be implemented with an interface configured to communicate signals with other layers (and modules) hosted by the DU 330, or with the control functions hosted by the CU 310.

[0065] Each RU 340 may implement lower-layer functionality. In some deployments, an RU 340, controlled by a DU 330, may correspond to a logical node that hosts RF processing functions or low-PHY layer functions, such as performing an FFT, performing an iFFT, digital beamforming, or PRACH extraction and filtering, among other examples, based on a functional split (for example, a functional split defined by the 3GPP), such as a lower layer functional split. In such an architecture, each RU 340 can be operated to handle over the air (OTA) communication with one or more UEs 120. In some implementations, real-time and non-real- time aspects of control and user plane communication with the RU(s) 340 can be controlled by the corresponding DU 330. In some scenarios, this configuration can enable each DU 330 and the CU 310 to be implemented in a cloud-based RAN architecture, such as a vRAN architecture.

[0066] The SMO Framework 305 may be configured to support RAN deployment and provisioning of non-virtualized and virtualized network elements. For non-virtualized network elements, the SMO Framework 305 may be configured to support the deployment of dedicated physical resources for RAN coverage requirements, which may be managed via an operations and maintenance interface (such as an 01 interface). For virtualized network elements, theSMO Framework 305 may be configured to interact with a cloud computing platform (such as an open cloud (O-Cloud) platform 390) to perform network element life cycle management (such as to instantiate virtualized network elements) via a cloud computing platform interface (such as an 02 interface). Such virtualized network elements can include, but are not limited to, CUs 310, DUs 330, RUs 340, non-RT RICs 315, and Near-RT RICs 325. In some implementations, the SMO Framework 305 can communicate with a hardware aspect of a 4G RAN, such as an open eNB (O-eNB) 311, via an 01 interface. Additionally, in some implementations, the SMO Framework 305 can communicate directly with each of one or more RUs 340 via a respective 01 interface. The SMO Framework 305 also may include a Non-RT RIC 315 configured to support functionality of the SMO Framework 305.

[0067] The Non-RT RIC 315 may be configured to include a logical function that enables non-real-time control and optimization of RAN elements and resources, Artificial Intelligence / Machine Learning (AI / ML) workflows including model training and updates, or policy-based guidance of applications / features in the Near-RT RIC 325. The Non-RT RIC 315 may be coupled to or communicate with (such as via an Al interface) the Near-RT RIC 325. The Near-RT RIC 325 may be configured to include a logical function that enables near-realtime control and optimization of RAN elements and resources via data collection and actions over an interface (such as via an E2 interface) connecting one or more CUs 310, one or more DUs 330, or both, as well as an O-eNB, with the Near-RT RIC 325.

[0068] 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 external servers. Such information may be utilized by the Near-RT RIC 325 and may be received at the SMO Framework 305 or the Non-RT RIC 315 from non-network data sources or from network functions. In some examples, the Non-RT RIC 315 or the 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 for performance and employ AI / ML models to perform corrective actions through the SMO Framework 305 (such as reconfiguration via an 01 interface) or via creation of RAN management policies (such as Al interface policies).

[0069] As indicated above, Fig. 3 is provided as an example. Other examples may differ from what is described with regard to Fig. 3.

[0070] Fig. 4 is a diagram illustrating an example 400 of joint communication-radar (JCR) systems, in accordance with the present disclosure.

[0071] In some examples, a network device (e.g., a UE 120, a network node 110, or a similar network device) may include JCR capability and / or include a JCR system. JCR systems may be systems that are capable of sharing frequency bands between radar and communication systems in a network device. In some instances, JCR systems may be categorized as cooperative JCRsystems, as schematically shown by reference number 402, or co-design JCR systems, as schematically shown by reference number 404.

[0072] In cooperative JCR systems, network devices, such as a first device 406 and a second device 408, may include separate radar and communication systems. For example, the first device 406 may include a radar system 410 and a communication system 412, and the second device 408 may similarly include a radar system 414 and a communication system 416. In such cases, some information may be shared between the radar systems 410, 414 and the corresponding communication systems 412, 416 to improve the systems’ performance without altering the core operation of the respective systems. In some cases, benefits realized by implementing a cooperative JCR system include spectrum reuse and ease of implementation as compared to other JCR systems.

[0073] In co-design JCR systems, network devices, such as a first device 418 and a second device 420, may include a common transmitter and / or receiver used for both communication and radar functionalities. 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 aspects, the JCRtransmitter / receivers 422, 424 may include functionality to generate various transmit waveforms (e.g., waveforms applicable to radar functionality as well as waveforms applicable to communication functionality) and / or may include functionality to process received waveforms of radar and / or communication systems. In some cases, benefits realized by implementing a co-design JCR system include spectrum reuse and hardware reuse.

[0074] In some cases, communication capabilities of a JCR system may utilize one type of waveform, such as a CP-OFDM waveform, and radar capabilities of a JCR system may utilize another type of waveform, such as a time division multiplexing (TDM) waveform. However, in some other cases, both communication capabilities and radar capabilities of a JCR system may utilize the same waveform, such as a CP-OFDM waveform.

[0075] As indicated above, Fig. 4 is provided as an example. Other examples may differ from what is described with respect to Fig. 4.

[0076] Fig. 5 is a diagram illustrating an example 500 of sensing by a UE, in accordance with the present disclosure.

[0077] In some aspects, a UE may perform a sensing procedure that detects a presence of an object. Alternatively, or additionally, the sensing procedure may detect one or more characteristics about the object, such as a shape, a size, and / or a velocity. One example of a sensing procedure may include a radar sensing procedure. A UE (e.g., a UE 120) performing the radar sensing procedure may transmit an RF signal that reflects off an object. The UE may receive the reflected RF signal and apply one or more signal processing techniques (e.g., radarsignal processing techniques) to the reflected signal to calculate and / or obtain information (e.g., characteristics) about the object. That is, the UE may sense a characteristic about the object based at least in part on processing the reflected RF signal.

[0078] Fig. 5 illustrates a UE in the form of a vehicle (e.g., a vehicle UE) that may perform a sensing procedure (e.g., a radar sensing procedure) to sense and / or detect surrounding objects. For example, the UE may perform the sensing procedure as part of an automotive application, such as a collision detection application and / or collision avoidance application. To illustrate, a first vehicle UE 502 may travel in a first direction at a first rate and / or speed of 12 meters per second (m / s), and a second vehicle UE 504 may 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 may be separated by a distance of X meters (not shown in Fig. 5). As shown by Fig. 5, a third vehicle UE 506 may travel in a second direction (e.g., a direction that is generally opposite of the first direction) at a third rate of 20 m / s.

[0079] In some aspects, the first vehicle UE 502 may transmit a CP-OFDM signal 508 that is associated with a field 510, shown by Fig. 5 as having a triangular shape. The field 510 may represent a field of view (FOV) that is associated with an instantaneous area perceivable by a radar sensing procedure and / or the CP-OFDM signal 508 at a point in time and / or a field of regard (FOR) that is a total area perceivable by the radar sensing procedure and / or the CP- OFDM signal 508 based at least in part on a sweeping procedure, such as that described below with regard to Fig. 6. Based at least in part on transmission of the CP-OFDM signal 508, the first vehicle UE 502 may detect a radar echo 512 that is associated with the second vehicle UE 504. In some aspects, the radar echo 512 may be based at least in part on the CP-OFDM signal, such as a reflection of the CP-OFDM signal off the second vehicle UE 504. Alternatively, or additionally, the first vehicle UE 502 may detect a radar echo 514 that is associated with the third vehicle UE 506, and the radar echo 514 may be based at least in part on the CP-OFDM signal (e.g., a second reflection of the CP-OFDM signal off the third vehicle UE 506). Based at least in part on the radar echo 512 and / or the 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 a respective presence, a respective velocity, and / or a respective distance associated with the second vehicle UE 504 and / or the third vehicle UE 506 based at least part on applying one or more radar signal processing techniques to the radar echo 512 and / or the radar echo 514, respectively.

[0080] In some aspects, one or more uplink resources may be reused for a sensing procedure by a UE as at least part of JCR sensing by the UE (e.g., UE-side JCR sensing). To illustrate, an uplink resource may be shared between a communication mode by a first UE and a radar mode by a second UE. As one example, an uplink resource may be shared between the communication mode and the radar mode based at least in part on using time divisionmultiplexing (TDM) to share the uplink resources. In some aspects, and based at least in part on using TDM, a sounding reference signal (SRS) may be utilized as a sensing waveform (e.g., a waveform used to detect a presence and / or characteristics of an object). As a second example, a same resource may be used for communication and radar with a joint co-design waveform (e.g., a waveform type that may be used as a communication waveform and a radar waveform). That is, a communication waveform and a radar waveform may share a same air interface resource based at least in part on the communication waveform and the radar waveform being based at least in part on the joint co-design waveform.

[0081] As indicated above, Fig. 5 is provided as an example. Other examples may differ from what is described with regard to Fig. 5.

[0082] Fig. 6 is a diagram illustrating an example 600 of an uplink sensing procedure, in accordance with the present disclosure.

[0083] Some use cases, such as an automotive use case as described with regard to Fig. 5, may involve a relatively high density of radar systems that operate with higher resolution and / or a higher update rate relative to other radar systems. To illustrate, vehicular radar systems may use a first resolution and / or a first update rate that enables the vehicular radar system to detect approaching objects (e.g., within 180 meters and / or up to a range accuracy of 0.725 meters), and an over-the-horizon radar system may operating with a second resolution and / or a second update rate to detect objects located over a horizon (e.g., within 20-40 kilometers and / or up to a range accuracy of 2-4 kilometers). Alternatively, or additionally, a vehicular radar system may operate in an environment that includes a higher density of radar systems (e.g., three or more radar systems) relative to other radar systems (e.g., stationary radar systems). For example, the mobile nature of a vehicular radar system may result in multiple vehicular radar systems operating within proximity of one another, resulting in the vehicular radar system(s) observing more interference originating from the other radar systems.

[0084] In some aspects, a single-phase uplink sensing configuration may use more communication overhead relative to a two-phase uplink sensing configuration. To illustrate, for a same update rate, a single-phase uplink sensing configuration may use 10% of air interface resources per-beam and / or per-user (e.g., in the sensing procedure) for signaling communication overhead, while a two-phase sensing configuration may use 9% of air interface resources peruser for signaling communication overhead. Accordingly, a first radar system that is configured to use a single-phase uplink sensing configuration may use more air interface resources relative to a second radar system that is configured to use the two-phase uplink sensing configuration. Accordingly, two-phase uplink sensing may be more suitable for multi-radar sensing that uses shared uplink communication resources. That is, based at least in part on the two-phase uplink sensing configuration using fewer air interface resources for overhead relative to single phaseuplink sensing, two-phase uplink sensing may better enable JCR sensing that uses a shared uplink resource relative to single-phase uplink sensing.

[0085] To illustrate, a single-phase uplink sensing procedure as shown by reference number 602 may be based at least in part on a coherent processing interval (CPI) 606, a 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 bounds. Example CPI (per beam) conditions may include a CPI duration of 5. 1 milliseconds (msec) that is associated with a bandwidth of 0.5 GHz and a subcarrier spacing (SCS) of 120 kHz configuration bound for a use case that is associated with sensing based at least in part on a carrier frequency of 73 GHz with a velocity resolution of 0.4 meters per second (m / s) and range resolution of 30 centimeters (cm).

[0086] As shown by Fig. 6, a single-phase uplink sensing procedure may sweep through multiple beams, shown as beam 608-1, beam 608-2, to beam 608-M, where n is an integer, and each beam may be associated with a respective CPI. That is, the single-phase uplink sensing procedure may be based at least in part on a plurality of CPIs, and each CPI may be associated with a respective beam of the multiple beams. Accordingly, for a 20 frames per second (fps) update rate that is associated with a 50 msec sensing period for a single-phase sensing procedure, approximately 10% of system resources may be used per beam and per user.

[0087] A two-phase uplink sensing procedure as shown by reference number 604 may include a scanning phase 610 and a tracking phase 612. The scanning phase 610 may be based at least in part on a scanning CPI 614 and a low-resolution beam 616. That is, the low- resolution beam 616 may have a first configuration that is associated with detecting a presence of a target, but not detecting high-resolution characteristics (e.g., a velocity resolution of 0.4 m / s and / or range resolution of 30 cm) associated with the target. Accordingly, the scanning phase 610 may be used by a device (e.g., a UE) to detect a target presence. As shown by Fig. 6, the scanning phase 610 may include multiple scanning CPIs and beam sweeping such that each CPI may be associated with a respective beam. Example operating conditions and / or configuration bounds associated with the scanning phase 610 may include a scanning CPI with a 1 msec duration being associated with a 150 MHz bandwidth and an SCS of 120 kHz, resulting in a velocity resolution of 2 m / s and a range resolution of 1 meter.

[0088] The tracking phase 612 may be based at least in part on a tracking CPI 618 and a high-resolution beam 620. In some aspects, the high-resolution beam 620 may have a second configuration that is associated with detecting refined and / or high-resolution characteristics associated with a target detected based at least in part on the scanning phase 610. That is, the second configuration of the high-resolution beam 620 may be used to calculate higher- resolution characteristics associated with the target relative to the first configuration associated with the low-resolution beam 616. Example operating conditions and / or configuration bounds associated with the tracking phase 612 may include a tracking CPI with a duration of 5 msecbeing associated with a bandwidth of 0.5 GHz, a comb-5 decimation in time (e.g., a one in every fifth symbol decimation) and a comb-4 decimation in frequency (e.g., a one in every fourth resource element (RE) decimation). For a 20 fps update rate associated with a two-phase sensing procedure, approximately 4.5% of system resources may be used per user and per detected target, and approximately 9% of system resources may be used per user assuming that two targets are within a field of view. Because two-phase sensing uses less communication overhead relative to single-phase sensing, two-phase sensing may be more applicable than single-phase sensing to use for multi-radar sensing that is based at least in part on shared uplink communication resources.

[0089] The expansion of 5G and 6G may include the addition of sensing procedures and / or sensing services, such as the addition of a long-range sensing procedure and / or a short-range sensing procedure as described above. The co-existence of communication transmissions and radar transmissions in a RAN may result in multiple types of interference, such as Rad-Rad interference, Rad-Comm interference, and / or Comm-Comm interference. In some aspects, Rad- Rad interference and Rad-Comm interference may affect a radar sensing procedure in a different manner than the effects of Comm-Comm interference on a communication procedure. For example, a radar waveform may differ in a time-frequency grid relative to a communication waveform, a radar sensing procedure may be more sensitive to two-way path loss and receive processing gain relative to a communication procedure, a monostatic radar sensing procedure may rely on more accurate synchronization relative to a communication procedure (e.g., an information transmission and / or recovery procedure), and / or radar interference may reduce an accuracy and / or resolution of a radar performance metric (e.g., a velocity accuracy and / or a range accuracy) relative to an effect of communication interface on a communication performance metric (e.g., a bit error metric and / or a spectral efficiency metric). Accordingly, interference management techniques used to mitigate the effects of Comm-Comm interference may be ineffective for mitigating the effects of Rad-Rad interference and / or Rad-Comm interference, resulting in increased errors and / or increased inaccuracies in radar sensing procedures. Alternatively, or additionally, the interference management techniques used to mitigate the effects of Comm-Comm interference may be ineffective for mitigating the effects of Rad-Comm interference in a communication procedure, resulting in increased recovery errors, reduced data throughput, and / or increased data transfer latencies.

[0090] Some techniques and apparatuses described herein provide ICS with IMC. A UE may obtain an ICS collision detection configuration indication that is based at least in part on an interference sensing procedure. In one example, the UE may obtain the ICS collision detection configuration indication by receiving the ICS collision detection configuration indication from another UE and / or a network node. In a second example, the UE may obtain the ICS collision detection configuration indication by generating the ICS collision detection configuration. TheICS collision detection configuration indication may specify one or more parameters that may be used to configure the interference sensing procedure. Accordingly, the UE may perform the interference sensing procedure based at least in part on the ICS collision detection configuration indication, such as by configuring the interface sensing procedure using the parameter(s). The UE may transmit an ICS interference message that is based at least in part on the interference sensing procedure, such as by transmitting an ICS measurement report that indicates one or more ICS measurement metrics generated by the interference sensing procedure and / or by transmitting an inter-UE coordination message that indicates assistance information that may mitigate interference detected by the interference sensing procedure.

[0091] A sensing UE (e.g., a radar UE 120 and / or a communication UE 120) receiving an indication of an ICS collision detection configuration may mitigate radar-based interference (e.g., Rad-Rad interference and / or Rad-Comm interference) in a radar sensing procedure and / or a communication procedure as described below. For example, the sensing UE may use the ICS collision detection configuration to identify an air interface resource that is associated with a potential collision between a communication transmission and a radar transmission, such as a sidelink air interface resource, and avoid use of the air interface resource. In some aspects, the sensing UE may forward an ICS message (e.g., an IMC measurement report and / or assistance information) to another wireless communication device (e.g., another UE 120 and / or a network node 110) that indicates the air interface resource that is associated with the potential collision and / or a transmission configuration (e.g., a radar transmission configuration). The use of an ICS collision detection configuration and / or an ICS message may enable the sensing device and / or the other wireless communication device to mitigate radar-based interference, such as by avoiding using an air interface resource (e.g., in a current transmission and / or a future reservation) that may be associated with the radar-based interference. Mitigating the radarbased interference enables more reliable monostatic radar sensing (e.g., an increased accuracy) and / or reliable bistatic communication (e.g., reduced bit errors, increased data throughput, and / or reduced data transfer latencies) in a sidelink.

[0092] As indicated above, Fig. 6 is provided as an example. Other examples may differ from what is described with regard to Fig. 6.

[0093] Fig. 7 is a diagram illustrating an example 700 of a wireless communication process between a first UE 702 (e.g., a first UE 120) and a second UE 704 (e.g., a second UE 120), in accordance with the present disclosure. In some aspects, the first UE 702 may be a radar UE that includes radar sensing capabilities, and the second UE 704 may be a communication UE that includes communication capabilities. Alternatively, or additionally, the first UE 702 may include communication capabilities and / or the second UE 704 may include radar capabilities.

[0094] As shown by reference number 710, the first UE 702 and the second UE 704 may establish a sidelink. In some aspects, the sidelink may use a PC5 interface and / or may operatein 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 synchronize timing of transmission time intervals (TTIs) (e.g., frames, subframes, slots, or symbols) using global navigation satellite system (GNSS) timing.

[0095] In some aspects, the sidelink may be based one or more sidelink channels, such as a physical sidelink control channel (PSCCH), a physical sidelink shared channel (PSSCH), and / or a physical sidelink feedback channel (PSFCH). The PSCCH may be used to communicate control information, similar to a physical downlink control channel (PDCCH) and / or a physical uplink control channel (PUCCH) used for cellular communications with a network node 110 via an access link or an access channel. The PSSCH may be used to communicate data, similar to a physical downlink shared channel (PDSCH) and / or a physical uplink shared channel (PUSCH) used for cellular communications with a network node 110 via an access link or an access channel. For example, the PSCCH may carry sidelink control information (SCI), which may indicate various control information used for sidelink communications, such as one or more resources (e.g., time resources, frequency resources, and / or spatial resources) where a transport block (TB) may be carried on the PSSCH. The PSFCH may be used to communicate sidelink feedback, such as hybrid automatic repeat request (HARQ) feedback (e.g., acknowledgement or negative acknowledgement (ACK / NACK) information), transmit power control (TPC), and / or a scheduling request (SR).

[0096] In some aspects, the one or more sidelink channels may use resource pools. For example, a scheduling assignment (e.g., included in SCI) may be transmitted in sub-channels using specific resource blocks (RBs) across time. In some aspects, data transmissions (e.g., on the PSSCH) associated with a scheduling assignment may occupy adjacent RBs in the same subframe as the scheduling assignment (e.g., using frequency division multiplexing). In some aspects, a scheduling assignment and associated data transmissions are not transmitted on adjacent RBs.

[0097] In some aspects, a 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 a network node 110 (e.g., a base station, a CU, or a DU). For example, a UE may receive a grant (e.g., in downlink control information (DCI) or in a radio resource control (RRC) message, such as for configured grants) from a network node 110 (e.g., directly or via one or more network nodes) for sidelink channel access and / or scheduling. In some aspects, a UE may operate using a transmission mode (e.g., Mode 2) where resource selection and / or scheduling is performed by the UE (e.g., rather than a network node 110). In some aspects, the UE may perform resource selection and / or scheduling by sensing channel availability for transmissions. For example, the UE may measure a received signal strength indicator (RS SI) parameter (e.g., a sidelink-RSSI (S-RSSI) parameter) associated with various sidelink channels, may measure areference signal received power (RSRP) parameter (e.g., a PSSCH-RSRP parameter) associated with various sidelink channels, and / or may measure a reference signal received quality (RSRQ) parameter (e.g., a PSSCH-RSRQ parameter) associated with various sidelink channels, and may select a channel for transmission of a sidelink communication based at least in part on the measurement(s).

[0098] As shown by reference number 720, the first UE 702 may obtain an ICS collision detection configuration, and the ICS collision detection configuration may indicate one or more parameters that may 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 a future time -frequency-space resource). In some aspects, the first UE 702 may generate the ICS collision detection configuration. In other aspects, the first UE 702 may receive the ICS collision detection configuration indication from another device (e.g., the second UE 704, a centralized controller (e.g., a managing UE for a group of UEs), and / or a network node 110). To illustrate, the first UE 702 may be configured to perform a radar sensing procedure (e.g., a radar UE) and, in some aspects, the ICS collision detection configuration may be based at least in part on a configuration of the radar sensing procedure. As one example, the ICS collision detection configuration may include, indicate, and / or be based at least in part on any combination of a time-frequency-space resource, a radar UE location, a radar UE trajectory, and / or a radar transmission parameter.

[0099] In some aspects, the time-frequency-space resource indicated by an ICS collision detection configuration may be a time-frequency-space resource (and / or may be associated with a future time-frequency-space resource) that the UE 702 plans to use for a radar transmission. The time-frequency-space resource may be associated with an interference mitigation and cancellation (IMC) capable UE. That is, the time-frequency-space resource may be used by an IMC capable UE that includes an IMC capability, and the time-frequency-space resource may be assigned to and / or categorized as a resource that may be used for both a radar transmission and a communication transmission. Accordingly, the first UE 702 may select, as a time- frequency-space resource to use for detecting and / or predicting interference, a time-frequency- space resource that may be used by an IMC capable UE. In other aspects, the time-frequency- space resource indicated by an ICS collision detection configuration may not be associated with an IMC capable UE. For instance, the time-frequency-space resource may be assigned to a legacy UE that does not include an IMC capability, may be categorized for only radar transmissions, and / or may be categorized for only communication transmissions.

[0100] As shown by reference number 730, the first UE 702 may transmit, and the second UE 704 may receive, an ICS collision detection configuration indication. While Fig. 7 illustrates the first UE 702 transmitting the ICS collision detection configuration indication to the second UE 704 via a sidelink, alternate or additional examples may include the first UE 702 transmitting the ICS collision detection indication to a network node 110 and / or a centralizedcontroller. By transmitting 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 use for an interference sensing procedure and / or one or more time-frequency-space resources that the first UE 702 plans to use for a radar transmission. As described above, the ICS collision detection configuration indication may indicate any combination of a time-frequency-space resource, a radar UE location, a radar UE trajectory, and / or a radar transmission parameter. While Fig. 7 illustrates the second UE 704 obtaining the ICS collision detection configuration by receiving an indication from the first UE 702, alternate or additional examples may include the second UE 704 obtaining the ICS collision detection configuration indication from a network node 110 and / or a centralized controller.

[0101] As shown by reference number 740-1, the first UE 702 may perform an interference sensing procedure (e.g., a radar interference sensing procedure and / or a radar interference detection procedure) that may be used to sense and / or detect interference (e.g., radar interference). Alternatively, or additionally, the second UE 704 may perform an interference sensing procedure (e.g., a radar interference sensing procedure) as shown by reference number 740-2. Accordingly, a sensing UE (e.g., a UE that performs the interference sensing procedure) may be a radar UE and / or a communication UE as described above.

[0102] In some aspects, the first UE 702 and / or the second UE 704 may perform the interference sensing procedure based at least in part on operating in an enabled and / or active interference sensing mode. An enabled and / or active sensing mode may include a sensing UE (e.g., a UE performing the interference sensing procedure, the first UE 702, and / or the second UE 704) not transmitting a signal (e.g., a radar transmission and / or a communication transmission). Based at least in part on operating in an enabled and / or active sensing mode, the sensing UE may be configured to receive a signal and / or calculate an interference measurement metric (e.g., an ICS measurement metric). In some aspects, the sensing UE may be configured to not transmit a signal when operating with the enabled sensing mode and / or to only receive a signal. Prior to operating in the enabled sensing mode, the sensing UE may operate in a disabled and / or an inactive sensing mode. A 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., a radar transmission and / or a communication transmission) instead of performing an interference sensing procedure. In some aspects, performing the interference sensing procedure may be disallowed in the disabled and / or inactive sensing mode.

[0103] As at least part of performing an interference sensing procedure, the sensing UE may calculate one or more interference measurement metrics (e.g., one or more ICS measurement metrics). As one example of an interference measurement metric, the sensing UE may calculate a receive interference power metric, such as by calculating the receive interference power metricusing a time-frequency-space resource indicated by the ICS collision detection configuration. Alternatively, or additionally, the sensing UE may calculate the receive interference power metric based at least in part on one or more range-angle-Doppler cells. “Range-angle-Doppler cell” may denote a cell and / or sensing area with a particular range metric, a particular angle metric, and / or a particular Doppler metric. Accordingly, a set of range-angle-Doppler cells may include cells and / or sensing areas that have 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 calculate the receive interference power metric using one or more cells (and / or one or more sensing areas).

[0104] In some aspects, and as at least part of performing the interference sensing procedure, the sensing UE may detect a presence of interference (e.g., radar interference) and / or a lack of interference based at least in part on a power threshold. For example, the sensing UE may analyze an interference measurement metric generated via the interference sensing procedure by comparing the interference measurement metric to the power threshold. Based at least in part on the interference measurement metric satisfying the power threshold, the sensing UE may detect the presence of interference. In some aspects, the power threshold may be based at least in part on one or more factors, such as a UE type associated with the UE (e.g., the sensing UE), an interference capability of the UE, an IMC capability of the UE, a radar sensing type associated with the UE, and / or an IMC capability type supported by the UE. To illustrate, a radar UE type may have a different power threshold relative to a communication UE type based at least in part on how interference affects a radar procedure (e.g., a radar accuracy) relative to a communication procedure (e.g., a bit error rate). For instance, an accuracy of a radar procedure may be more impacted (e.g., may become more inaccurate) in the presence of a particular amount of interference relative to a bit error rate of a communication procedure (or vice versa). Alternatively, or additionally, a first power threshold for a radar UE (e.g., that performs a monostatic radar sensing procedure) may be higher for a target that is within a distance threshold due to better synchronization, higher transmit power, and / or more processing gain relative to a second power threshold that is associated with a communication UE and / or a second radar UE that has a target outside of the distance threshold. In some aspects, a first sensing UE that includes an IMC capability may be more tolerant to the particular amount of interference relative to a second sensing UE that does not include IMC capability. Other examples may include differences in an efficacy of different radar sensing procedures and / or different types of IMC capabilities. To illustrate, a first interference mitigation technique (e.g., a first IMC technique) may include performing interference cancellation after perfect signal reconstruction that is based at least in part on the UE including a communication decode capability, and a second interference mitigation technique (e.g., a second IMC technique) that includes zeroing a signal that includes communication interference (e.g., Comm-Comminterference) in overlapping resources. The first interference mitigation technique may support interference mitigation at higher interference power levels relative to the first interference mitigation technique. Accordingly, a power level for a first UE that supports the first interference mitigation technique may be higher relative to a second power level for a second UE that supports the second interference technique (e.g., and does not support the first interference technique).

[0105] Alternatively, or additionally, as at least part of performing an interference sensing procedure, the sensing UE may calculate one or more sensing performance metrics. Some nonlimiting examples of a sensing performance metric may include a range metric, a velocity metric, an angular field of view metric, a sensing resolution metric, a range-velocity-angle domain sensing accuracy metric, a latency and update rate metric, a number of detected targets, an intersection over union (loU) metric that is associated with a target bounding box, and / or a quality-of-service (QoS) metric.

[0106] In some aspects, the sensing UE may detect a presence of interference (and / or a lack of presence) based at least in part on a quality threshold. To illustrate, and in a similar manner as described above, the sensing UE may compare a calculated sensing performance metric to the quality threshold and / or a detection threshold. The sensing UE may detect a presence of interference based at least in part on calculating a decrease in sensing performance (e.g., accuracy) and / or a decrease in a QoS that satisfies the detection threshold.

[0107] A sensing UE (e.g., the first UE 702 and / or the second UE 704) may perform a single instance of the interference procedure and / or multiple instances of the interference procedure. In some aspects, the sensing UE may perform the interference sensing procedure periodically and / or using a periodic configuration. That is, the sensing UE may perform the interference sensing procedure at a particular periodicity and / or using a particular duration (e.g., a sampling duration). In some aspects, the periodic configuration may be preconfigured (e.g., set by a communication standard and / or indicated by a network node 110). Alternatively, or additionally, the periodic configuration may be selected based on one or more operating factors. To illustrate, the periodic configuration of the sensing UE may be based at least in part on any combination of a sensing application type, a sensing QoS condition, a radar target density, and / or a number of transmitting UEs within a distance threshold (e.g., indicated by a channel busy ratio (CBR) and / or a channel occupancy ratio (CR)). In some aspects, the sensing UE may determine the periodic configuration, while in other aspects, another wireless communication device (e.g., a network node 110 and / or a centralized controller) may indicate the periodic configuration to the sensing UE. Alternatively, or additionally, the periodic configuration may be selected and / or coordinated by a group of UEs. For instance, the periodic configuration may be selected and / or coordinated by the group of UEs to form an interference sensing cluster thatmay mitigate interference management better relative to single and / or autonomous interference sending by a singular UE.

[0108] As shown by reference number 750, the first UE 702 may transmit, and the second UE 704 may receive, a first ICS interference message. Alternatively, or additionally, as shown by reference number 760, the second UE 704 may transmit, and the first UE 702 may receive, a second ICS interference message. In some aspects, the ICS interference message may be and / or include an ICS measurement report that indicates one or more interference measurement metrics (e.g., one or ICS interference measurement metrics), such as an interference measurement metric described with regard to reference number 740-1 and reference number 740-2.

[0109] Alternatively, or additionally, the ICS interference message may be and / or include an inter-UE coordination message that indicates assistance information. For example, the assistance information may provide information about a radar transmission and / or IMC of the radar transmission. To illustrate, the first UE 702 (e.g., a radar UE) may detect a conflict and / or a presence in a time-frequency-space resource (e.g., via the interference sensing procedure as described with regard to reference number 740-1) that the first UE 702 plans to use for a radar transmission. In some aspects, the first UE 702 may transmit, as the ICS interference message, an inter-UE coordination message that indicates assistance information that may be used by the second UE 704 for IMC. As one example, the assistance information may indicate a waveform type (e.g., a frequency modulated continuous wave (FMCW) type, a pulse modulated continuous wave (PMCW) type and / or an OFDM type) of a radar transmission, specifications of a particular waveform type, such as a chirp slope, a bandwidth, and / or a carrier frequency of an FMCW type, a transmission power associated with the radar transmission, a transmission radiation pattern associated with the radar transmission, and / or a radar transmitter location (e.g., a front of a vehicle, a back of a vehicle, a passenger side of a vehicle, a driver side of a vehicle, and / or a bumper of a vehicle). In some aspects, the UE transmitting the assistance information (e.g., the first UE 702 and / or the second UE 704) may generate the assistance information. Alternatively, or additionally, the inter-UE coordination message may include assistance information from multiple wireless communication devices. For example, the first UE 702 may generate first assistance information associated with a first radar transmission, and / or may receive, from another wireless communication device (e.g., a third UE 120, another radar UE, and / or another communication UE), second assistance information associated with a second radar transmission. In some aspects, the first UE 702 may indicate the first assistance information and the second assistance information in the inter-UE coordination message. Alternatively, or additionally, the second assistance information may include information that may be used by a communication UE, such as a time-of-arrival metric that enables a communication UE to mitigate synchronization errors and / or timing errors.

[0110] The assistance information may be based at least in part on a subset of interference measurement metrics. To illustrate, and as described with regard to reference number 740-1 and reference number 740-2, a sensing UE (e.g., the first UE 702 and / or the second UE 704) may calculate multiple interference measurement metrics, and the sending UE may generate the assistance information using a subset of interference measurement metrics that are included in the multiple interference measurement metrics. For instance, as at least part of an interference sensing procedure, a sensing UE may calculate a respective collision metric for each of the multiple interference measurement metrics (e.g., a probability of a collision and / or a collision detection), and may select the subset of interference metrics using the multiple collision metrics. To illustrate, a sensing UE may generate a collision metric for each slot of a five-slot radar transmission that indicates whether the sensing UE has detected interference in the respective slot. Accordingly, the sensing UE may generate five collision metrics. In some aspects, the sensing UE may only include, in the assistance information, information that is associated with detecting a collision. For instance, the sensing UE may detect a potential collision (e.g., via a respective collision metric) for a second slot of the five slots and / or may detect no potential collision in the other four slots. Accordingly, the sensing UE may indicate relevant assistance information (e.g., a subset of information) that indicates a potential collision (e.g., only assistance information about the second slot).

[0111] Alternatively, or additionally, the assistance information may include transmit information. To illustrate, the assistance information may include first transmit information that may be used by a radar UE to transmit a radar transmission and / or second transmit information (e.g., timing advance information) that may be used by a communication UE to transmit a communication as described above. In some aspects, the transmit 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 may be used to encode and / or recover encrypted information. The security information may be used by a receiving UE (e.g., a receiving communication UE) to perform a soft cancellation interference mitigation and / or to process high priority communications. Alternatively, or additionally, a security key and / or initial seed may be used by a transmitting UE (e.g., a transmitting communication UE) to use a same time-frequency-space resource for a communication transmission, such as for transmitting the high priority communications. In some aspects, an identifier (ID) used for the transmission may be a default ID and / or a common ID that is known to multiple UEs and / or wireless communication devices.

[0112] As shown by reference number 770, the first UE 702 may perform a radar sensing procedure, such as by transmitting a radar transmission and / or processing a received echo as described above. In some aspects, the first UE 702 may perform the radar sensing procedure using information indicated by one or more ICS interference messages. For example, the firstUE 702 may generate a radar transmission based at least in part on using a waveform type, a transmission power level, and / or a time-frequency-space resource. As another example, the first UE 702 may refrain from using the time-frequency-space resource, such as a time-frequency- space resource that may overlap with a communication transmission.

[0113] As shown by reference number 780, the second UE 704 may perform a communication procedure, such as by transmitting and / or receiving a communication (e.g., a sidelink communication and / or an access link communication). In some aspects, the first UE 702 may perform the communication procedure using information indicated by one or more ICS interference messages. For example, the first UE 702 may transmit the communication by refraining from using a time -frequency-space resource indicated by the ICS interface message, such as a time-frequency-space resource indicated as including interference. Alternatively, or additionally, the first UE 702 may use transmit information to generate the communication and / or to perform soft cancellation as described above.

[0114] A sensing UE receiving an indication of an ICS collision detection configuration may mitigate radar-based interference in a radar sensing procedure and / or a communication procedure. For example, the sensing UE may use the ICS collision detection configuration to identify an air interface resource that is associated with a potential collision between a communication transmission and a radar transmission, such as a sidelink air interface resource, and avoid use of the air interface resource. In some aspects, the sensing UE may forward an ICS message to another wireless communication device that indicates the air interface resource that is associated with the potential collision and / or a transmission configuration. Mitigating the radar-based interference may result in more reliable monostatic radar sensing (e.g., an increased accuracy) and / or more reliable bistatic communication (e.g., reduced bit errors, increased data throughput, and / or reduced data transfer latencies) in a sidelink.

[0115] As indicated above, Fig. 7 is provided as an example. Other examples may differ from what is described with regard to Fig. 7.

[0116] Fig. 8 is a diagram illustrating an example process 800 performed, for example, at a UE or an apparatus of a UE, in accordance with the present disclosure. Example process 800 is an example where the apparatus or the UE (e.g., UE 120) performs operations associated with ICS with IMC.

[0117] As shown in Fig. 8, in some aspects, process 800 may include obtaining an ICS collision detection configuration indication that is associated with an interference sensing procedure (block 810). For example, the UE (e.g., using reception component 902 and / or communication manager 906, depicted in Fig. 9) may obtain an ICS collision detection configuration indication that is based at least in part on an interference sensing procedure, asdescribed above. To illustrate, the UE may obtain the ICS collision detection configuration as described with regard to reference number 720 of Fig. 7.
