[0003] All aspects of this disclosure relate to wireless communication, and to techniques and apparatus for broadband interference measurement.

[0004] Related technical descriptions

[0005] Wireless communication systems are widely deployed to provide a variety of telecommunications services, such as telephone, video, data, messaging, and broadcasting. Typical wireless communication systems employ multiple access technologies that can support communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access technologies include Code Division Multiple Access (CDMA) systems, Time Division Multiple Access (TDMA) systems, Frequency Division Multiple Access (FDMA) systems, Orthogonal Frequency Division Multiple Access (OFDMA) systems, Single Carrier Frequency Division Multiple Access (SC-FDMA) systems, Time Division Synchronous Code Division Multiple Access (TD-SCDMA) systems, and Long Term Evolution (LTE). LTE / LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard issued by the 3rd Generation Partnership Project (3GPP).

[0006] A wireless network may include one or more network nodes that support communication for wireless communication devices, such as user equipment (UE) or multiple UEs. A UE may communicate with network nodes via downlink and uplink communication. A "downlink" (or "DL") refers to the communication link from the network node to the UE, and an "uplink" (or "UL") refers to the communication link from the UE to the network node. Some wireless networks may support device-to-device communication, such as via local links (e.g., sidelinks (SL), wireless local area network (WLAN) links, and / or wireless personal area network (WPAN) links, etc.).

[0007] These multiple access technologies have been adopted in various telecommunications standards to provide a common protocol that enables different UEs to communicate at the city, country, region, or global level. New Radio (NR) (also known as 5G) is a set of enhancements to the LTE mobile standard issued by 3GPP. NR is designed to better support mobile broadband internet access by: improving spectrum efficiency; reducing costs; improving service; utilizing new spectrum; and using Orthogonal Frequency Division Multiplexing (OFDM) with Cyclic Prefix (CP) (CP-OFDM) on the downlink and CP-OFDM or Single Carrier Frequency Division Multiplexing (SC-FDM) (also known as Discrete Fourier Transform Extended OFDM (DFT-s-OFDM)) on the uplink to better integrate with other open standards; and supporting beamforming, multiple-input multiple-output (MIMO) antenna technologies and carrier aggregation.

[0030] Figure 12 This is a diagram of an example device for wireless communication according to the present disclosure. Detailed Implementation

[0031] In some examples, the User Equipment (UE) can estimate an Orthogonal Frequency Division Multiplexing (OFDM) channel based on one or more received signals to improve the reliability and throughput of transmission and reception performed by the wireless device. In some examples, the UE can receive OFDM signals via an OFDM channel. The UE can use an analog-to-digital converter (ADC) to convert the received analog OFDM signal into a digital signal. The received signal can be a time-domain signal. The UE can then perform a Fast Fourier Transform (FFT) on the time-domain digital signal to convert it into one or more frequency-domain signals. The UE can use the frequency-domain signals to estimate the OFDM channel in the frequency domain. In some examples, the sampling rate of the ADC at the UE can be relatively high to accurately convert the analog OFDM signal into digital form. Additionally or alternatively, performing an FFT to convert the time-domain signal to the frequency domain is relatively complex.

[0032] Therefore, in some cases, the UE can use a Frequency Modulated Continuous Waveform (FMCW) signal to perform OFDM channel estimation. The transmitting device can transmit a first FMCW signal for channel estimation via an OFDM channel. The UE can receive the first FMCW signal and can use a set of FMCW parameters associated with the first FMCW signal to generate a second (e.g., local) FMCW signal. The UE can combine the first and second FMCW signals and can filter the combined signal (e.g., using a low-pass filter (LPF) or some other type of filter). The UE can estimate the frequency-domain OFDM channel by sampling the combined FMCW signal using a relatively low sampling rate. The sampling rate used by the UE can be based on one or more parameters of the OFDM channel, such as the bandwidth of the OFDM channel and / or the subband frequency size.

[0033] In some examples, wireless communication devices can measure interference on OFDM channels. As described above, using an analog receiver (e.g., an FMCW-based receiver) to measure interference on OFDM channels can be beneficial (e.g., to reduce the ADC sampling rate and / or save power). However, using an analog receiver and / or an FMCW-based receiver to measure interference on OFDM channels can introduce one or more problems (e.g., these problems may not exist when performing FMCW-based channel estimation on OFDM channels). For example, for FMCW-based channel estimation, the transmitting device and the UE can be configured and / or instructed to use one or more parameters to generate an FMCW signal (e.g., for transmission or local use at the receiving device for FMCW-based channel estimation). However, for interference measurement, different devices can use different waveforms and / or different parameters to transmit different signals for measurement by the receiving device. For example, to measure interference on a wireless channel, the receiving device can measure signals transmitted by devices from neighboring cells and / or devices within the same cell using different waveforms and / or different transmission parameters. Therefore, it may be difficult to identify the parameters that the UE can use to perform interference measurements on the OFDM channel using an FMCW-based receiver (e.g., because it may be difficult to predict the waveform type and / or parameters of the signal measured by a receiving device that uses an analog receiver or an FMCW receiver to measure interference on the OFDM channel).

[0034] The various aspects generally relate to wireless communication, and more specifically to wideband interference measurements of OFDM channels. Some aspects more specifically relate to wideband interference measurements of OFDM channels performed by the UE using an analog receiver and / or an FMCW-based receiver. As used herein, "wideband" interference measurement can refer to measuring interference measurement resources associated with a frequency domain range that is greater than the frequency domain range of the UE's narrowband baseband capabilities (e.g., the baseband capabilities of the UE's digital receiver or OFDM-based receiver). In some aspects, the UE may transmit, and network nodes may receive, a capability report indicating one or more capability parameters that the UE 120 uses to perform wideband interference measurements of OFDM channels.

[0035] These one or more capability parameters enable a network node to configure interference measurement resources for the UE, allowing the UE to perform wideband interference measurements on OFDM channels using an FMCW-based receiver (e.g., regardless of the transmitting device and / or the waveform type associated with the signal causing the interference). For example, these one or more capability parameters may include a supported wideband bandwidth for wideband interference measurements, a supported ADC sampling rate for wideband interference measurements, and / or a supported interference measurement granularity for wideband interference measurements.

[0036] Network nodes may send, and UEs may receive, configuration information indicating interference measurement resources associated with a frequency domain resource set. In some aspects, the frequency domain resource set includes a larger number of frequency domain resources than the supporting subband size (e.g., the supporting subband size for OFDM communication and / or the supporting baseband size). In other words, the interference measurement resources may be wideband resources. In some aspects, the configuration information may instruct the UE to use an analog receiver and / or an FMCW-based receiver to measure interference on the OFDM channel via the interference measurement resources. In other aspects, the UE 120 may determine, based on, in response to, or otherwise associated with the interference measurement resources being wideband resources, that the analog receiver and / or FMCW-based receiver will be used to measure interference on the OFDM channel via the interference measurement resources. The UE may (e.g., using an analog receiver and / or an FMCW-based receiver) measure the interference measurement resources to obtain interference measurement information associated with the OFDM channel. The UE may send, and network nodes may receive, measurement reports indicating the interference measurement information.

[0037] Specific aspects of the subject matter described in this disclosure can be implemented to achieve one or more of the following potential advantages. In some aspects, by measuring interference on an OFDM channel via broadband interference measurement, the UE can reduce the ADC sampling rate used to measure the interference and / or save power associated with performing interference measurements on the OFDM channel. For example, by using an analog receiver and / or an FMCW-based receiver, the UE 120 can perform interference measurements on an OFDM channel while also saving processing resources and / or power resources, etc.

[0038] In some respects, by sending capability reports, the UE can be configured using broadband interference measurement resources to enable it to measure interference on OFDM channels (e.g., using an analog receiver and / or an FMCW-based receiver), regardless of the transmitting device and / or the waveform type of the signal causing the interference. For example, there may be a relationship between the measured broadband bandwidth, ADC sampling rate, and subband granularity. By having the UE report the supported broadband bandwidth, supported ADC sampling rate, and supported granularity for broadband interference measurement, the network node can ensure that the configured interference measurement resources and / or the measurement reporting granularity configured by the UE are actually supported by the UE (e.g., regardless of the transmitting device and / or the waveform type associated with the signal causing the interference).

[0039] Various aspects of this disclosure are described more fully below with reference to the accompanying drawings. However, this disclosure may be embodied in many different forms and should not be construed as limited to any particular structure or function presented throughout this disclosure. Rather, these aspects are provided so that this disclosure will be comprehensive and complete, and will fully convey the scope of this disclosure to those skilled in the art. Those skilled in the art will appreciate that the scope of this disclosure is intended to cover any aspect of this disclosure disclosed herein, whether implemented independently or in combination with any other aspect of this disclosure. For example, any number of aspects set forth herein may be used to implement an apparatus or method of practice. Furthermore, the scope of this disclosure is intended to cover such apparatuses or methods implemented using structures, functionalities, or structures and functionalities other than or different from the various aspects of the disclosure set forth herein. It should be understood that any aspect of the disclosure herein may be embodied by one or more elements of these claims.

[0040] Various devices and techniques will now be used to illustrate several aspects of a telecommunications system. These devices and techniques will be described in detail below and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, or algorithms (collectively, “elements”). These elements may be implemented using hardware, software, or a combination thereof. Whether these elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the system as a whole.

[0041] Although terms generally associated with 5G or New Radio (NR) Radio Access Technology (RAT) may be used herein to describe aspects, aspects of this disclosure may be applied to other RATs, such as 3G RAT, 4G RAT and / or 5G and later (e.g., 6G) RATs.

[0042] Figure 1This is an illustration of an example of a wireless network 100. Wireless network 100 can be a 5G (e.g., NR) network or a 4G (e.g., LTE) network, or may include elements of a 5G (e.g., NR) network or elements of a 4G (e.g., LTE) network, etc. Wireless network 100 may include one or more network nodes 110 (shown as network nodes 110a, 110b, 110c, and 110d), one or more UEs 120 (shown as UEs 120a, 120b, 120c, 120d, and 120e), or other entities. Network node 110 is an example of a network node communicating with UE 120. As shown, network node 110 may include one or more network nodes. For example, network node 110 can be an aggregated network node, meaning that the aggregated network node is 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). As another example, network node 110 can be a decomposed network node (sometimes referred to as a decomposed base station), meaning that network node 110 is configured to utilize a protocol stack that is physically or logically distributed among two or more nodes (such as one or more central units (CUs), one or more distributed units (DUs), or one or more radio units (RUs)).

[0043] In some examples, network node 110 is a network node (such as RU) that communicates with UE 120 via a radio access link, or includes network nodes (such as RU) that communicate with the UE via a radio access link. In some examples, network node 110 is a network node (such as DU) that communicates with other network nodes 110 via a fronthaul link or a midhaul link, or includes network nodes (such as DU) that communicate with other network nodes 110 via a fronthaul link or a midhaul link. In some examples, network node 110 is a network node (such as CU) that communicates with other network nodes 110 via a midhaul link or with the core network via a backhaul link, or includes network nodes (such as CU) that communicate with other network nodes 110 via a midhaul link or with the core network via a backhaul link. In some examples, network node 110 (such as aggregated network node 110 or decomposed network node 110) may include multiple network nodes, such as one or more RUs, one or more CUs, and / or one or more DUs. For example, network node 110 may include NR base stations, LTE base stations, node Bs, eNBs (e.g., in 4G), gNBs (e.g., in 5G), access points, transmit / receive points (TRPs), DUs, RUs, CUs, network mobility elements, core network nodes, network elements, network equipment, RAN nodes, or combinations thereof. In some examples, network nodes 110 may interconnect with each other or with one or more other network nodes 110 in the wireless network 100 using any suitable transport network through various types of fronthaul interfaces, midhaul interfaces, and / or backhaul interfaces (such as direct physical connections, air interfaces, or virtual networks).

[0044] In some examples, network node 110 may provide communication coverage for a specific geographic area. In the 3rd Generation Partnership Project (3GPP), depending on the context in which the term is used, the term "cell" may refer to the coverage area of ​​network node 110 or a network node subsystem serving that coverage area. Network node 110 may provide communication coverage for macrocells, picocells, femtocells, or another type of cell. A macrocell may cover a relatively large geographic area (e.g., with a radius of several kilometers) and may allow unrestricted access by UE 120 with a service subscription. A picocell may cover a relatively small geographic area and may allow unrestricted access by UE 120 with a service subscription. A femtocell may cover a relatively small geographic area (e.g., a residential area) and may allow restricted access by UE 120 associated with that femtocell (e.g., UE 120 in a Closed Subscriber Group (CSG)). Network node 110 used for macrocells may be referred to as a macro network node. Network node 110 used for picocells may be referred to as a pico network node. The network node 110 used for femtocells can be referred to as a femtocell network node or a home network node. Figure 1 In the example shown, network node 110a may be a macro network node for macro cell 102a, network node 110b may be a pico network node for pico cell 102b, and network node 110c may be a femto network node for femto cell 102c. Network nodes may support one or more (e.g., three) cells. In some examples, the cells may not necessarily be stationary, and the geographical area of ​​the cells may move depending on the location of the mobile network node 110 (e.g., a mobile network node).

[0045] In some aspects, the term "base station" or "network node" may refer to an aggregated base station, a decomposed base station, an integrated access and backhaul (IAB) node, a relay node, or one or more components thereof. For example, in some aspects, "base station" or "network node" may refer to a CU, DU, RU, a near real-time (near RT) RAN intelligent controller (RIC), or a non-real-time (non-RT) RIC, or a combination thereof. In some aspects, the term "base station" or "network node" may refer to a device configured to perform one or more functions (such as those described herein in conjunction with network node 110). In some aspects, the term "base station" or "network node" may refer to multiple devices configured to perform one or more functions. For example, in some distributed systems, each of multiple different devices (which may be located in the same geographical location or different geographical locations) may be configured to perform at least a portion of a function, or to repeatedly perform at least a portion of that function, and the term "base station" or "network node" may refer to any one or more of these different devices. In some aspects, the term "base station" or "network node" may refer to one or more virtual base stations or one or more virtual base station functions. For example, in some aspects, two or more base station functions can be instantiated on a single device. In some aspects, the term "base station" or "network node" may refer to one base station function rather than another. In this way, a single device can include more than one base station.

[0046] Wireless network 100 may include one or more relay stations. A relay station is a network node that receives data transmissions from an upstream node (e.g., network node 110 or UE 120) and transmits data to a downstream node (e.g., UE 120 or network node 110). A relay station may be a UE 120 that can relay transmissions to other UE 120s. Figure 1 In the example shown, network node 110d (e.g., a relay network node) can communicate with network node 110a (e.g., a macro network node) and UE 120d to facilitate communication between network node 110a and UE 120d. The network node 110 for relay communication may be referred to as a relay station, relay base station, relay network node, relay node, or relay, etc.

[0047] The wireless network 100 can be a heterogeneous network, comprising different types of network nodes 110, such as macro network nodes, pico network nodes, femto network nodes, or relay network nodes. These different types of network nodes 110 may have different transmit power levels, different coverage areas, or different effects on interference in the wireless network 100. For example, macro network nodes may have high transmit power levels (e.g., 5 watts to 40 watts), while pico network nodes, femto network nodes, and relay network nodes may have lower transmit power levels (e.g., 0.1 watts to 2 watts).

[0048] Network controller 130 may be coupled to or communicate with a group of network nodes 110, and may provide coordination and control for these network nodes 110. Network controller 130 may communicate with network nodes 110 via a backhaul or midhaul link. Network nodes 110 may also communicate directly with each other, or indirectly via a wireless or wired backhaul link. In some aspects, network controller 130 may be a CU or core network device, or may include a CU or core network device.

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

[0050] Some UEs 120 may be considered machine-type communication (MTC) or evolved or enhanced machine-type communication (eMTC) UEs. MTC UEs or eMTC UEs may include, for example, robots, unmanned aerial vehicles, remote devices, sensors, meters, monitors, or location markers that can communicate with network nodes, another device (e.g., a remote device), or some other entity. Some UEs 120 may be considered Internet of Things (IoT) devices or may be implemented as NB-IoT (Narrowband IoT) devices. Some UEs 120 may be considered customer premises equipment. UEs 120 may be included within a housing that houses the components of the UE 120, such as processor components or memory components. In some examples, the processor components and memory components may be coupled together. For example, the processor components (e.g., one or more processors) and memory components (e.g., memory) may be operatively coupled, communicatively coupled, electronically coupled, or electrically coupled.

[0051] Generally, any number of wireless networks 100 can be deployed in a given geographical area. Each wireless network 100 can support a specific RAT and can operate on one or more frequencies. A RAT can also be referred to as a radio technology or air interface. A frequency can also be referred to as a carrier or frequency channel. Each frequency can support a single RAT in a given geographical area to avoid interference between wireless networks using different RATs. In some cases, NR or 5G RAT networks can be deployed.

[0052] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more sidelink channels (e.g., without using network node 110 as an intermediary for communication with each other). For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, or vehicle-to-pedestrian (V2P) protocols), or mesh networks. In such examples, UE 120 may perform scheduling operations, resource selection operations, or other operations described elsewhere herein as being performed by network node 110.

[0053] Devices in Wireless Network 100 can communicate using the electromagnetic spectrum, which can be subdivided into various categories, bands, or channels by frequency or wavelength. For example, devices in Wireless Network 100 can communicate using one or more operating bands. In 5G NR, two initial operating bands have been designated as frequency ranges FR1 (410MHz to 7.125GHz) and FR2 (24.25GHz to 52.6GHz). Although a portion of FR1 is greater than 6GHz, in various documents and articles, FR1 is often (interchangeably) referred to as the “sub-6GHz” band. Similar naming issues sometimes occur with FR2, which is often (interchangeably) referred to in documents and articles as the “millimeter wave” band, although this is different from the Extremely High Frequency (EHF) band (30GHz–300GHz) designated as a “millimeter wave” band by the International Telecommunication Union (ITU).

[0054] The frequencies between FR1 and FR2 are generally referred to as mid-band frequencies. Recent 5G NR studies have designated the operating bands for these mid-band frequencies as the frequency range designation FR3 (7.125 GHz – 24.25 GHz). Bands falling within FR3 can inherit FR1 or FR2 characteristics, thus effectively extending the features of FR1 or FR2 into the mid-band frequencies. Furthermore, higher frequency bands are currently being explored to extend 5G NR operation beyond 52.6 GHz. For example, three higher operating frequency bands have been designated as the frequency range designations FR4a or FR4-1 (52.6 GHz to 71 GHz), FR4 (52.6 GHz to 114.25 GHz), and FR5 (114.25 GHz to 300 GHz). Each of these higher frequency bands falls within the EHF band.

[0055] In light of these examples, unless otherwise specifically stated, the term "below 6 GHz" as used herein can broadly refer to frequencies less than 6 GHz, frequencies within FR1, or frequencies that may include intermediate frequency bands. Furthermore, unless otherwise specifically stated, the term "millimeter wave" as used herein can broadly refer to frequencies that may include intermediate frequency bands, frequencies within FR2, FR4, FR4-a, FR4-1, or FR5, or frequencies within the EHF band. It is conceivable that the frequencies included in these operating frequency bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, or FR5) can be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0056] In some aspects, UE 120 may include a communication manager 140. As described in more detail elsewhere herein, the communication manager 140 may send a capability report to a network node indicating one or more capability parameters associated with wideband interference measurements of an OFDM channel and a support subband size for the OFDM channel; receive configuration information from the network node based on sending the capability report, the configuration information indicating interference measurement resources associated with a set of frequency domain resources, wherein the set of frequency domain resources includes a number of frequency domain resources larger than the support subband size; measure the interference measurement resources based on receiving the configuration information to obtain interference measurement information associated with the OFDM channel; and send a measurement report to the network node indicating the interference measurement information. Additionally or alternatively, the communication manager 140 may perform one or more other operations described herein.

[0057] In some aspects, network node 110 may include communication manager 150. As described in more detail elsewhere herein, communication manager 150 may receive a capability report associated with a UE, indicating one or more capability parameters related to wideband interference measurements of an OFDM channel and a support subband size for the OFDM channel; send configuration information to the UE based on receiving the capability report, indicating interference measurement resources associated with a set of frequency domain resources, wherein the set of frequency domain resources includes a larger number of frequency domain resources than the support subband size; and receive a measurement report associated with the UE, indicating interference measurement information associated with the interference measurement resources and the OFDM channel. Additionally or alternatively, communication manager 150 may perform one or more other operations described herein.

[0058] As indicated above, Figure 1 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 1 The examples described are different.

[0059] Figure 2 This is a diagram illustrating example 200 of communication between network node 110 and UE 120 in wireless network 100. Network node 110 may be equipped with a set of antennas 234a to 234t, such as... T One antenna ( T ≥1). The UE 120 may be equipped with a set of antennas 252a to 252r, such as R One antenna ( R ≥1). Network node 110 of Example 200 includes one or more radio frequency components, such as antenna 234 and modem 232. In some examples, network node 110 may include an interface, communication components, or another component that facilitates communication with UE 120 or another network node. Some network node 110 may not include radio frequency components that facilitate direct communication with UE 120, such as one or more CUs or one or more DUs.

[0060] At network node 110, transmitting processor 220 can receive data from data source 212 intended for use by UE 120 (or a group of UEs 120). Transmitting processor 220 can use one or more Channel Quality Indicators (CQIs) received from UE 120 to select one or more modulation and decoding schemes (MCSs) for that UE 120. Network node 110 can use the MCS selected for UE 120 to process (e.g., encode and modulate) the data for UE 120 and can provide data symbols to UE 120. Transmitting processor 220 can process system information (e.g., semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, or upper-layer signaling) and provide overhead symbols and control symbols. Transmitting processor 220 can generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signal (PSS) or secondary synchronization signal (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 can perform spatial processing (e.g., pre-decoding) on ​​data symbols, control symbols, overhead symbols, or reference symbols (if applicable), and can direct to a corresponding set of modems 232 shown as modems 232a to 232t (e.g., T A set of output symbol streams (e.g., modems) is provided by a modem. T Each output symbol stream can be provided to a modulator component (shown as MOD) of modem 232. Each modem 232 can use a corresponding modulator component to process the corresponding output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modem 232 can also use a corresponding modulator component to process (e.g., convert to analog, amplify, filter, or upconvert) the output sample stream to obtain a downlink signal. Modems 232a to 232t can be connected via a corresponding set of antennas 234 (e.g., T Each antenna (shown as antennas 234a to 234t) is used to transmit a set of downlink signals (e.g., T (One downlink signal).

[0061] At UE 120, the set of antennas 252 (shown as antennas 252a to 252r) can receive downlink signals from network node 110 or other network nodes 110, and can transmit signals to the set of modems 254 (e.g., R Each modem (shown as modems 254a to 254r) provides a set of received signals (e.g., REach received signal may be provided to a demodulator component (shown as DEMOD) of modem 254. Each modem 254 may use a corresponding demodulator component to condition (e.g., filter, amplify, down-convert, or digitize) the received signal to obtain an input sample. Each modem 254 may use a demodulator component to further process the input sample (e.g., for OFDM) to obtain a received symbol. MIMO detector 256 may obtain the received symbols from modem 254, perform MIMO detection on the received symbols where applicable, and provide the detected symbols. Receiver processor 258 may process (e.g., demodulate and decode) the detected symbols, provide the decoded data for UE 120 to data sink 260, and provide the decoded control information and system information to controller / processor 280. The term "controller / processor" may refer to one or more controllers, one or more processors, or a combination thereof. Channel processor may determine Reference Signal Received Power (RSRP) parameters, Received Signal Strength Indicator (RSSI) parameters, Reference Signal Received Quality (RSRQ) parameters, or CQI parameters, etc. In some examples, one or more components of UE 120 may be included in housing 284.

[0062] Network controller 130 may include communication unit 294, controller / processor 290, and memory 292. Network controller 130 may include one or more devices, for example, in a core network. Network controller 130 may communicate with network node 110 via communication unit 294.

[0063] One or more antennas (e.g., antennas 234a to 234t or antennas 252a to 252r) may include or be included in the following: one or more antenna panels, one or more antenna groups, one or more collections of antenna elements, or one or more antenna arrays, etc. Antenna panels, antenna groups, collections of antenna elements, or antenna arrays may include one or more antenna elements (within a single housing or multiple housings), coplanar antenna element collections, non-coplanar antenna element collections, or coupled to one or more transmitting or receiving components (such as...). Figure 2 One or more antenna elements (one or more components).

[0064] On the uplink, at UE 120, transmit processor 264 can receive and process data from data source 262 and control information (e.g., reports including RSRP, RSSI, RSRQ, or CQI) from controller / processor 280. Transmit processor 264 can generate reference symbols for one or more reference signals. Symbols from transmit processor 264 may be pre-decoded by TX MIMO processor 266 where applicable, further processed by modem 254 (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to network node 110. In some examples, modem 254 of UE 120 may include a modulator and demodulator. In some examples, UE 120 includes a transceiver. The transceiver may include antenna 252, modem 254, MIMO detector 256, receive processor 258, transmit processor 264, or any combination of TX MIMO processor 266. The transceiver may be used by processor (e.g., controller / processor 280) and memory 282 to perform textual (e.g., reference) functions. Figures 7 to 12 ( ) any aspect of the process described in the process.

[0065] At network node 110, uplink signals from UE 120 or other UEs may be received by antenna 234, processed by modem 232 (e.g., demodulator component of modem 232, shown as DEMOD), detected by MIMO detector 236 where applicable, and further processed by receiver processor 238 to obtain decoded data and control information transmitted via UE 120. Receiver processor 238 may provide the decoded data to data sink 239 and the decoded control information to controller / processor 240. Network node 110 may include communication unit 244 and may communicate with network controller 130 via communication unit 244. Network node 110 may include scheduler 246 to schedule one or more UEs 120 for downlink or uplink communication. In some examples, modem 232 of network node 110 may include modulator and demodulator. In some examples, network node 110 includes transceiver. The transceiver may include any combination of antenna 234, modem 232, MIMO detector 236, receive processor 238, transmit processor 220, or TX MIMO processor 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to execute this document (e.g., reference). Figures 7 to 12 ( ) any aspect of the process described in the process.

[0066] In some respects, the controller / processor 280 may be a component of a processing system. A processing system can typically be a system or a series of machines or components that receive input and process it to produce output (which may be passed to other systems or components, such as UE 120). For example, the processing system of UE 120 may be a system that includes various other components or sub-components of UE 120.

[0067] The processing system of UE 120 can interface with one or more other components of UE 120, and can process information (such as input or signals) received from one or more other components, or can output information to one or more other components. For example, the chip or modem of UE 120 may include: a processing system, a first interface for receiving or acquiring information, and a second interface for outputting, transmitting, or providing information. In some examples, the first interface may be an interface between the processing system of the chip or modem and a receiver, allowing UE 120 to receive information or signal input and to pass information to the processing system. In some examples, the second interface may be an interface between the processing system of the chip or modem and a transmitter, allowing UE 120 to transmit information output from the chip or modem. Those skilled in the art will readily recognize that the second interface may also acquire or receive information or signal input, and the first interface may also output, transmit, or provide information.

[0068] In some respects, the controller / processor 240 may be a component of a processing system. A processing system can typically be a system or a series of machines or components that receive input and process it to produce output (which may be passed to other systems or components, such as network node 110). For example, the processing system of network node 110 may be a system that includes various other components or sub-components of network node 110.

[0069] The processing system of network node 110 can interface with one or more other components of network node 110, and can process information (such as input or signals) received from one or more other components, or can output information to one or more other components. For example, the chip or modem of network node 110 may include: a processing system, a first interface for receiving or acquiring information, and a second interface for outputting, transmitting, or providing information. In some examples, the first interface may be an interface between the processing system of the chip or modem and a receiver, allowing network node 110 to receive information or signal input and to pass information to the processing system. In some examples, the second interface may be an interface between the processing system of the chip or modem and a transmitter, allowing network node 110 to transmit information output from the chip or modem. Those skilled in the art will readily recognize that the second interface may also acquire or receive information or signal input, and the first interface may also output, transmit, or provide information.

[0070] The controller / processor 240 of network node 110, the controller / processor 280 of UE 120, or Figure 2 Any other component may perform one or more techniques associated with broadband interference measurement, as described in more detail elsewhere herein. For example, the controller / processor 240 of network node 110, the controller / processor 280 of UE 120, or... Figure 2 Any other component (or combination of components) may perform or direct, for example, as described herein. Figure 9 The process 900 Figure 10 The operation of process 1000 and / or other processes. Memory 242 and memory 282 may store data and program code for network node 110 and UE 120, respectively. In some examples, memory 242 and memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code or program code) for wireless communication. For example, the one or more instructions may cause the one or more processors, UE 120, or network node 110 to perform or direct, for example, when executed by one or more processors of network node 110 or UE 120 (e.g., directly, or after compilation, transformation, or interpretation). Figure 9 The process 900 Figure 10 The operation of process 1000 and / or other processes as described herein. In some examples, the execution instructions may include run instructions, transform instructions, compile instructions and / or interpret instructions, etc.

[0071] In some aspects, UE 120 includes components for sending a capability report to a network node, the capability report indicating one or more capability parameters associated with broadband interference measurements of an OFDM channel and a support subband size for the OFDM channel; components for receiving configuration information from the network node based on sending the capability report, the configuration information indicating interference measurement resources associated with a set of frequency domain resources, wherein the set of frequency domain resources includes a number of frequency domain resources larger than the support subband size; components for measuring the interference measurement resources based on receiving the configuration information to obtain interference measurement information associated with the OFDM channel; and / or components for sending a measurement report indicating the interference measurement information to the network node. Components enabling UE 120 to perform the operations described herein may include, for example, one or more of a communication manager 140, an antenna 252, a modem 254, a MIMO detector 256, a receive processor 258, a transmit processor 264, a TXMIMO processor 266, a controller / processor 280, or a memory 282.

[0072] In some aspects, network node 110 includes components for receiving a capability report associated with a UE, the capability report indicating one or more capability parameters associated with broadband interference measurements of an OFDM channel and a support subband size for the OFDM channel; components for transmitting configuration information to the UE based on receiving the capability report, the configuration information indicating interference measurement resources associated with a set of frequency domain resources, wherein the set of frequency domain resources includes a larger number of frequency domain resources than the support subband size; and / or components for receiving a measurement report associated with the UE, the measurement report indicating interference measurement information associated with the interference measurement resources and the OFDM channel. Components for network node 110 to perform the operations described herein may include, for example, one or more of a communication manager 150, a transmit processor 220, a TX MIMO processor 230, a modem 232, an antenna 234, a MIMO detector 236, a receive processor 238, a controller / processor 240, a memory 242, or a scheduler 246.

[0073] Although Figure 2 The boxes in the diagram are illustrated as different components, but the functions described above with respect to these boxes may be implemented in a single hardware, software, or combined component, or in various combinations of components. For example, the functions described for transmit processor 264, receive processor 258, and / or TX MIMO processor 266 may be performed by or under the control of controller / processor 280.

[0074] In some respects, a single processor can perform all the functions described as being performed by that one or more processors. In other respects, the one or more processors can jointly perform a set of functions. For example, a first group(s) of the one or more processors can perform a first function described as being performed by that one or more processors, and a second group(s) of the one or more processors can perform a second function described as being performed by that one or more processors. The first group and the second group of processors can be the same group of processors or can be different groups of processors. The reference to "one or more processors" should be understood as referring to a combination of functions. Figure 2 Any one or more processors described. The reference to "one or more memories" should be understood to refer to any one or more memories of the corresponding device, such as those in conjunction with... Figure 2 The memory described. For example, a function described as being performed by one or more memories can be performed by the same subset of the one or more memories or by different subsets of the one or more memories.

[0075] As indicated above, Figure 2 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 2 The examples described are different.

[0076] The deployment of communication systems such as 5G NR systems can be arranged in a variety of ways using various components or parts. In a 5G NR system or network, network nodes, network entities, network mobility elements, RAN nodes, core network nodes, network elements, base stations, or network equipment can be implemented in either a converged or decomposed architecture. For example, a base station (such as a Node B (NB), evolved NB (eNB), NR base station, 5G NB, access point (AP), TRP, or cell, etc.) or one or more units (or components) performing base station functionality can be implemented as a converged base station (also known as a standalone base station or monolithic base station) or a decomposed base station. A "network entity" or "network node" can refer to a decomposed base station or one or more units of a decomposed base station (such as one or more CUs, one or more DUs, one or more RUs, or combinations thereof).

[0077] Aggregated base stations (e.g., aggregated network nodes) can be configured to utilize a radio protocol stack that is physically or logically integrated within a single RAN node (e.g., within a single device or cell). Decomposed base stations (e.g., decomposed network nodes) can be configured to utilize a protocol stack that is physically or logically distributed across two or more cells (such as one or more CUs, one or more DUs, or one or more RUs). In some examples, the CU may be implemented within a network node, and one or more DUs may be co-located with the CU, or alternatively, may be geographically or virtually distributed across one or more other network nodes. DUs may be implemented to communicate with one or more RUs. Each of the CU, DU, and RU can also be implemented as a virtual cell, such as a Virtual Central Unit (VCU), a Virtual Distributed Unit (VDU), or a Virtual Radio Unit (VRU), etc.

[0078] Base station type operation or network design can take into account the aggregation characteristics of base station functionality. For example, decomposed base stations can be utilized in IAB networks, Open Radio Access Networks (O-RAN (such as network configurations initiated by the O-RAN Alliance)), or Virtualized Radio Access Networks (vRAN, also known as Cloud Radio Access Networks (C-RAN)) to facilitate the scaling of communication systems by separating base station functionality into one or more units that can be deployed independently. Decomposed base stations can include functionality implemented across two or more units at various physical locations, as well as functionality virtually implemented for at least one unit, which enables flexibility in network design. Each unit of a decomposed base station can be configured for wired or wireless communication with at least one other unit of the decomposed base station.

[0079] In some respects, this document describes actions performed by network node 110 that can be performed by multiple different network nodes. For example, configuration actions may be performed by a first network node (e.g., CU or DU), and radio communication actions may be performed by a second network node (e.g., DU or RU). As used herein, network node 110 “outputting” or “transmitting” communication to UE 120 can refer to direct transmission (e.g., from network node 110 to UE 120) or indirect transmission via one or more other network nodes or devices. For example, if network node 110 is a DU, indirect transmission to UE 120 may include the DU outputting or transmitting communication to an RU and the RU transmitting communication to UE 120, or may include causing the RU to transmit communication (e.g., triggering the transmission of a physical layer reference signal). Similarly, UE 120 “transmitting” communication to network node 110 can refer to direct transmission (e.g., from UE 120 to network node 110) or indirect transmission via one or more other network nodes or devices. For example, if network node 110 is a DU, indirect transmissions to network node 110 may include UE 120 sending communication to RU and RU sending communication to the DU. Similarly, network node 110 “receiving” communication may refer to directly receiving a transmission carrying communication (e.g., from UE 120 to network node 110) or receiving communication (or information derived from receiving communication) via one or more other network nodes or devices.

[0080] Figure 3 This is an illustration of an example disaggregated base station architecture 300 according to the present disclosure. The disaggregated base station architecture 300 may include a CU 310, which may communicate directly with the core network 320 via a backhaul link, or indirectly with the core network 320 via one or more disaggregated control units (such as near-RT RIC 325 via an E2 link, or a non-RT RIC 315 associated with a Service Management and Orchestration (SMO) framework 305, or both). The CU 310 may communicate with one or more DUs 330 via a corresponding midhaul link (such as via an F1 interface). Each DU 330 may communicate with one or more RUs 340 via a corresponding fronthaul link. Each RU 340 may communicate with one or more UEs 120 via a corresponding radio frequency (RF) access link. In some implementations, a UE 120 may be served simultaneously by multiple RUs 340.

[0081] Each unit in the clusters (including CU 310, DU 330, RU 340), as well as the near-RT RIC 325, non-RT RIC 315, and SMO frame 305, may include or be coupled to one or more interfaces configured to receive or transmit signals, data, or information (collectively, signals) via wired or wireless transmission media. Each unit in the cluster, or an associated processor or controller providing instructions to one or more communication interfaces of the corresponding unit, may be configured to communicate with one or more units in other clusters via transmission media. In some examples, each unit in the cluster may include a wired interface and a wireless interface configured to receive signals or transmit signals to one or more units in other clusters via a wired transmission media, and the wireless interface may include a receiver, transmitter, or transceiver (such as an RF transceiver) configured to receive signals or transmit signals to one or more units in other clusters via a wireless transmission media, or both.

[0082] In some aspects, the CU 310 can host one or more higher-level control functions. Such control functions may include Radio Resource Control (RRC) functions, Packet Data Convergence Protocol (PDCP) functions, or Service Data Adaptation Protocol (SDAP) functions, etc. Each control function can be implemented using an interface configured to signal to other control functions hosted by the CU 310. The CU 310 can be configured to handle user plane functions (e.g., Central Unit-User Plane (CU-UP) functions), control plane functions (e.g., Central Unit-Control Plane (CU-CP) functions), or combinations thereof. In some implementations, the CU 310 can be logically divided into one or more CU-UP units and one or more CU-CP units. When implemented in an O-RAN configuration, the CU-UP units can communicate bidirectionally with the CU-CP units via an interface such as an E1 interface. The CU 310 can be implemented to communicate with the DU 330 for network control and signaling purposes, as needed.

[0083] Each DU 330 may correspond to a logical unit that includes one or more base station functions for controlling the operation of one or more RU 340s. In some aspects, the DU 330 may host one or more of the Radio Link Control (RLC) layer, the Media Access Control (MAC) layer, and one or more high physical (PHY) layers, at least in part, according to functional splits (such as those defined by 3GPP). In some aspects, the one or more high PHY layers may be implemented by one or more modules for forward error correction (FEC) encoding and decoding, scrambling, and modulation and demodulation, etc. In some aspects, the DU 330 may also host one or more low PHY layers, such as those implemented by one or more modules for FFT, inverse FFT (iFFT), digital beamforming, or physical random access channel (PRACH) extraction and filtering, etc. Each layer (which may also be referred to as a module) may be implemented using an interface configured to communicate signals with other layers (and modules) hosted by the DU 330 or with control functions hosted by the CU 310.

[0084] Each RU 340 can implement lower-layer functionality. In some deployments, an RU 340 controlled by a DU 330 can correspond to a logical node that hosts RF processing functions or low-PHY layer functions, such as performing FFT, performing iFFT, digital beamforming, or PRACH extraction and filtering, based on function splitting (e.g., function splitting defined by 3GPP) (such as lower-layer function splitting). In such architectures, each RU 340 can be operated to handle over-the-air (OTA) communications with one or more UEs 120. In some specific implementations, the real-time and non-real-time aspects of control plane and user plane communications with the RU 340 can be controlled by the corresponding DU 330. In some scenarios, this configuration allows each DU 330 and CU 310 to be implemented in a cloud-based RAN architecture, such as a vRAN architecture.

[0085] The SMO framework 305 can be configured to support RAN deployment and provisioning of both non-virtualized and virtualized network elements. For non-virtualized network elements, the SMO framework 305 can be configured to support the deployment of dedicated physical resources for RAN coverage requirements, which can be managed via operation and maintenance interfaces such as the O1 interface. For virtualized network elements, the SMO framework 305 can be configured to interact with cloud computing platforms such as the Open Cloud (O-Cloud) platform 390 to perform network element lifecycle management (such as instantiating virtualized network elements) via cloud computing platform interfaces such as the O2 interface. Such virtualized network elements may include, but are not limited to, CU 310, DU 330, RU 340, non-RT RIC 315, and near-RTTRIC 325. In some specific implementations, the SMO framework 305 may communicate with the hardware aspects of the 4G RAN, such as the Open eNB (O-eNB) 311, via the O1 interface. Additionally, in some implementations, the SMO framework 305 can communicate directly with each of one or more RUs 340 via a corresponding O1 interface. The SMO framework 305 may also include a non-RT RIC 315 configured to support the functionality of the SMO framework 305.

[0086] The non-RT RIC 315 can be configured to include logical functions enabling non-real-time control and optimization of RAN elements and resources, including AI / ML workflows for model training and updates, or policy-based guidance for applications / features in the near-RT RIC 325. The non-RT RIC 315 can be coupled to or communicate with the near-RT RIC 325, such as via an A1 interface. The near-RT RIC 325 can be configured to include logical functions enabling near real-time control and optimization of RAN elements and resources via an interface, such as an E2 interface, connecting one or more CU 310s, one or more DU 330s, or both, and O-eNBs to the near-RT RIC 325.

[0087] In some implementations, to generate AI / ML models to be deployed in the near-RT RIC 325, the non-RT RIC 315 may receive parameters or external enrichment information from an external server. This information can be utilized by the near-RT RIC 325 and can be received from non-network data sources or network functions at the SMO framework 305 or the non-RT RIC 315. In some examples, the non-RT RIC 315 or near-RT RIC 325 may be configured to tune RAN behavior or performance. For example, the non-RT RIC 315 may monitor long-term trends and patterns in performance and employ AI / ML models to perform corrective actions via the SMO framework 305 (such as reconfiguration via the O1 interface) or via the creation of RAN management policies (such as A1 interface policies).

[0088] As indicated above, Figure 3 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 3 The examples described are different.

[0089] Figure 4 This is a diagram illustrating Example 400 associated with OFDM channel measurements according to this disclosure. In some examples, the OFDM channel estimation scheme can be combined with... Figures 1 to 5 The aspects described. For example... Figure 4 As shown, transmitting device 405 (e.g., network node 110, UE 120, base station, RU, DU, CU, and / or IAB node) and receiving device 410 (e.g., network node 110, UE 120, base station, RU, DU, CU, and / or IAB node) can exchange OFDM signals via wireless channel 435 (which may be an OFDM channel). Receiving device 410 can use frequency domain signal processing to measure wireless channel 435. Measurements performed by receiving device 410 (e.g., measurements of wireless channel 435) may be channel estimation measurements and / or interference measurements.

[0090] Transmitting device 405 and receiving device 410 may establish a wireless communication connection via wireless channel 435. Transmitting device 405 may generate an OFDM signal to be transmitted to receiving device 410 via wireless channel 435. To generate the OFDM signal, transmitting device 405 may identify data scheduled to be transmitted to receiving device 410. This data may include or be converted into a set of frequency domain signals 415 (e.g., {X(0), X(1), ... X(N_c-1)}). Transmitting device 405 may perform an iFFT 420 on the frequency domain signals 415 to convert the frequency domain signals 415 into a time domain signal (e.g., X(m)).

[0091] Transmitting device 405 may perform a cyclic prefix addition 425 on the time-domain signal. For example, transmitting device 405 may add a cyclic prefix to the time-domain signal to generate an OFDM signal. Transmitting device 405 may then use a digital-to-analog converter (DAC) 430 to convert the time-domain signal from a digital signal to an analog signal. In some examples, transmitting device 405 may convert the real and imaginary parts of the digital time-domain signal to the analog domain, respectively. Transmitting device 405 may transmit the analog time-domain OFDM signal to receiving device 410 via wireless channel 435. In other examples, transmitting device 405 may not transmit the signal via wireless channel 435 during interference measurement resources (e.g., configured time-domain and / or frequency-domain allocations), and receiving device 410 may perform interference measurements on wireless channel 435 in a manner similar to that described below.

[0092] Receiver 410 can receive analog time-domain OFDM signals (signals and / or interference signals transmitted by transmitter 405) and convert the received signals to the digital domain using ADC 440 at receiver 410. In some examples, receiver 410 can convert the real and imaginary parts of the analog signal to the digital domain respectively. Receiver 410 can perform cyclic prefix removal 445 after using ADC 440 to remove the cyclic prefix from the time-domain digital signal. After removing the cyclic prefix, receiver 410 can perform an FFT 450 on the digital time-domain signal. FFT 450 can convert the time-domain signal to the frequency domain. That is, FFT 450 can generate a set of frequency-domain signals 455.

[0093] Receiver 410 can use a set of frequency-domain signals 455 generated by FFT 450 to estimate a frequency-domain OFDM channel (e.g., the frequency domain of radio channel 435). In some examples, to estimate a frequency-domain OFDM channel based on OFDM signals, the ADC 440 at receiver 410 can be a relatively high-rate ADC 440. That is, the sampling rate of ADC 440 can be relatively high to accurately convert analog OFDM signals into digital OFDM signals. The sampling rate can be defined in megasamples per second (Msps). The sampling rate can be calculated based on the subcarrier spacing (SCS) value and the corresponding FFT size, and can be associated with the number of corresponding subcarriers (sc) (e.g., in terms of the number of physical resource blocks (PRBs)). For example, the sampling rate can be equal to the product of SCS and FFT size (NFFT) (e.g., 15 kHz). 2048 = 30.72MHz).

[0094] In some examples, performing the FFT 450 by the receiving device 410 may be associated with relatively high processing and complexity. Additionally or alternatively, the ADC 440 at the receiving device 410 may be a relatively high-rate ADC 440. The sampling rate used to convert the received analog signal into digital form may be relatively high for the receiving device 410 to accurately convert the OFDM signal and subsequently perform the FFT 450.

[0095] As indicated above, Figure 4 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 4 The examples described are different.

[0096] Figure 5 This is a diagram of Example 500 related to FMCW-based channel estimation of OFDM channels according to this disclosure.

[0097] In some examples, FMCW-based channel estimation schemes can achieve a combination of... Figures 1 to 4 The aspects described. For example... Figure 5 As shown, transmitting device 505 (e.g., network node 110, UE 120, base station, RU, DU, CU, and / or IAB node) and receiving device 510 (e.g., network node 110, UE 120, base station, RU, DU, CU, and / or IAB node) can exchange FMCW signals via OFDM channel 515. The FMCW signals can be used to facilitate channel estimation of the frequency-domain OFDM channel by the receiving device 510. The FMCW signals may also be referred to as "FMCW chirps".

[0098] In some examples, FMCW-based channel estimation of the OFDM channel can be used to mitigate one or more of the problems described above. For example, transmitting device 505 and receiving device 510 can exchange FMCW signals via radio channel 435. The FMCW signal can be configured for channel estimation of the OFDM channel 515 and can support reduced processing complexity at receiving device 510. For example, the FMCW signal can be sampled at a lower sampling rate compared to the OFDM signal and can be used to estimate the frequency-domain OFDM channel using time-domain signal processing, allowing receiving device 510 to avoid performing an FFT (e.g., the frequency-domain OFDM channel can be directly estimated via time-domain signaling processing without performing an FFT), which reduces complexity compared to estimating the OFDM channel using the OFDM signal.

[0099] Transmitting device 505 and receiving device 510 may establish a connection for wireless communication via OFDM channel 515. In some examples, the devices may exchange one or more capability messages, control messages, or both to initiate the FMCW-based OFDM channel estimation process described herein. After initiating the FMCW-based OFDM channel estimation process, transmitting device 505 may generate an FMCW signal 520 (e.g., a first FMCW signal). In some examples, transmitting device 505 may use a voltage-controlled oscillator (VCO) 545 to generate the FMCW signal 520 in the analog domain. Transmitting device 505 may use at least one antenna element at transmitting device 505 to transmit the FMCW signal 520 via OFDM channel 515. In some aspects, VCO 545 and / or the at least one antenna element may be included in one or more communication interfaces of transmitting device 505. The analog domain FMCW signal 520 generated and transmitted by transmitting device 505 may be represented by Equation 1. express.

[0100] (1)

[0101] As shown in Equation 1, the FMCW signal 520 can be a time-domain signal (e.g., a function of time(t)). In the example of Equation 1, This can represent the starting frequency of the FMCW signal 520 as 590. This can represent the slope of the FMCW signal 520 as 585, and It can represent the phase of the transmitting device 505.

[0102] like Figure 5 As shown, the FMCW signal 520 may be associated with a waveform signal transmitted via a symbol 580 in the time domain and a bandwidth 570 (e.g., BW) in the frequency domain of the OFDM channel 515 (e.g., the FMCW signal 520 may be a wideband signal). The bandwidth 570 may include one or more resource blocks 575 in the frequency domain. In some examples, each resource block 575 may include a set of resource elements in the frequency domain. The OFDM channel 515 may include one or more symbols 580 in the time domain. The duration or length of each symbol 580 may correspond to the length of an OFDM symbol, or the length of an OFDM symbol and the corresponding cyclic prefix duration, or a partial length of an OFDM symbol, or a partial length of an OFDM symbol and the corresponding cyclic prefix duration, or some other length longer than the length of an OFDM symbol and the length of an OFDM symbol and the cyclic prefix duration, or some other symbol duration, or any combination thereof. The FMCW signal 520 may span a frequency between a starting frequency 590 and the sum of the starting frequency 590 and the bandwidth 570 (e.g., , ).

[0103] The FMCW signal 525 (e.g., a radio frequency signal) received by the receiving device 510 via the OFDM channel 515 in response to the FMCW signal 520 transmitted by the transmitting device 505 can be represented by Equation 2. express.

[0104] (2)

[0105] In the example of equation 2, This can represent the number of channel delay paths (e.g., the number of multipaths) associated with OFDM channel 515, and It can represent having an index The given channel delay. That is, the FMCW signal 525 can be used at various channel delays (e.g., =0 to The sample was taken from the sample. This can represent the conditions of OFDM channel 515, and This can represent channel noise. In some examples, the channel noise may be associated with a relatively small value relative to other values ​​of the radio frequency FMCW signal 525 received by the receiving device 510 as defined in Equation 2.

[0106] As described herein, receiving device 510 can generate an FMCW signal 530 at receiving device 510. The FMCW signal 530 generated at receiving device 510 may be referred to as a second FMCW signal or a local FMCW signal. Receiving device 510 can generate the FMCW signal 530 in the analog domain using VCO 555 at receiving device 510. Receiving device 510 can generate the FMCW signal 530 simultaneously with or after receiving FMCW signal 525. The FMCW signal 530 generated by receiving device 510 can be represented by Equation 3. express.

[0107] (3)

[0108] As shown in Equation 3, receiving device 510 can generate FMCW signal 530 based on a set of FMCW parameters associated with FMCW signal 520 transmitted by transmitting device 505. The set of FMCW parameters may include, for example, the starting frequency 590 of FMCW signal 520. The slope of the FMCW signal 520 is 585 ( ), and / or the initial phase of the transmitting device (e.g., (or any combination thereof). That is, the FMCW signal 530 generated by the receiving device 510 may have the same starting frequency 590 and slope 585 as the FMCW signal 520 generated by the transmitting device 505. In the example of Equation 3, This can represent the phase of the receiving device 510. In some examples, the phase of the receiving device 510 may be the same as the phase of the transmitting device 505 (e.g., ).

[0109] The FMCW signal 520 transmitted by transmitting device 505 and the FMCW signal 530 generated at receiving device 510 may have similar FMCW structures. For example, both signals (e.g., FMCW signal 520 and FMCW signal 530) may be wideband signals (e.g., spanning the full bandwidth 570 of OFDM channel 515), spanning the duration of symbols 580 in OFDM channel 515, associated with a starting frequency 590, and associated with a slope 585. In some examples, the FMCW signal 520 transmitted by transmitting device 505 may be a real signal. For example, FMCW signal 520 may include a single stream (e.g., a cosine stream, as shown in Equation 1). The FMCW signal 530 generated by receiving device 510 may include two streams (e.g., a sine stream and a cosine stream) for channel estimation. That is, the exponential function in the FMCW signal 530 generated by receiving device 510 may be designed for channel estimation. In some examples, the receiving device 510 may be configured with the function of generating the FMCW signal 530 for channel estimation, or the receiving device 510 may receive a control message indicating the function of generating the FMCW signal 530 for channel estimation.

[0110] After generating the FMCW signal 530 configured for channel estimation, the receiving device 510 can generate a combined FMCW signal 535 (e.g., To generate the combined FMCW signal 535, receiving device 510 may use mixer 550 to combine the FMCW signal 525 received at receiving device 510 with the locally generated FMCW signal 530. Mixer 550 may represent an example of receiving device 510 configured to combine one or more components (e.g., hardware, software, or both) of two or more time-domain FMCW signals. In some examples, combining may include multiplying the FMCW signals (e.g., ...). ).

[0111] The receiving device 510 can use the LPF 560 at the receiving device 510 to filter the combined FMCW signal 535. The LPF 560 can generate a combined and filtered FMCW signal 540 (e.g., LPF 560 may represent an example of a component of receiving device 510 configured to filter a signal, and / or a function supported by receiving device 510. For example, receiving device 510 may apply the LPF function to the combined FMCW signal 535 (e.g., ).

[0112] After combining and filtering the FMCW signals, the receiving device 510 can perform frequency-domain OFDM channel estimation using time-domain signal processing based on sampling of the combined and filtered FMCW signals 540. The receiving device 510 can use an ADC 565 to sample the combined and filtered FMCW signals 540 in the time domain. The sampling rate used to sample the combined and filtered FMCW signals 540 can be based on one or more parameters associated with the OFDM channel 515. For example, the sampling rate can be based on the frequency range of one or more sub-bands in the OFDM channel 515 (e.g., sampling rate). Can be equal to (The reciprocal of the value). Subband frequency range This indicates that the receiving device 510 can estimate the granularity of the OFDM channel 515 in the frequency domain.

[0113] The sampling performed by the receiving device 510 as part of the OFDM channel estimation can generate a sampling sequence. This sampling sequence can represent a set of values ​​associated with OFDM channel estimation. The sampling sequence can have granularity. .For example, Each value can represent an example of an estimate of the corresponding frequency subband of OFDM channel 515.

[0114] The receiving device 510 can thus perform time-domain signal processing and granular processing based on the FMCW signal 525 received at the receiving device 510 and the FMCW signal 530 generated by the receiving device 510. The frequency-domain OFDM channel 515 is estimated using FMCW-based OFDM channel estimation. The described FMCW-based OFDM channel estimation technique can be performed in the time domain by the receiving device 510 using time-domain signal processing. That is, when using an FMCW signal to estimate the frequency-domain OFDM channel 515, the receiving device 510 can avoid applying FFT or other frequency transforms. By performing OFDM channel estimation in the time domain, compared to other OFDM channel estimation schemes performed at least partially in the frequency domain (e.g., using FFT) (such as combining...),... Figure 4 Compared to the described OFDM channel estimation scheme, receiver 510 can reduce processing complexity, latency, and / or power consumption. Additionally or alternatively, receiver 510 can use both wideband and narrowband RF processing to estimate the frequency-domain OFDM channel 515. For example, the FMCW signal 525 received at receiver 510 can be a wideband signal in RF, and the combined and filtered FMCW signal 540 after LPF 560 can be a narrowband signal for baseband processing.

[0115] The receiving device 510 uses the FMCW signal to estimate the frequency domain OFDM channel 515, and the sampling rate used can be relatively low. The sampling rate described herein can be based on the slope 585 of the FMCW signal and the frequency granularity. For example, the sampling rate can be equal to... ,in This represents the number of resource elements in each frequency subband (e.g., each sampled portion of a frequency-domain OFDM channel 515). Some OFDM channel estimation schemes (e.g., as referenced...) Figure 6 The sampling rate (as described) can be equal to the FFT size. With SCS The product (e.g., Therefore, the ratio of the sampling rate of the FMCW-based OFDM channel estimation described in this paper to that of the OFDM-based OFDM channel estimation technique can be expressed by Equation 4. express.

[0116] (4)

[0117] As shown in Equation 4, the ratio between the sampling rate of the FMCW-based OFDM channel estimation scheme and the sampling rate of the OFDM channel estimation scheme can be relatively low. For example, the sampling rate of the FMCW-based OFDM channel estimation scheme can be relatively low compared to the OFDM-based OFDM channel estimation scheme. In one example, if there are 273 in a bandwidth of 570... 12 resource elements (e.g., ), and each subband includes a single resource element (e.g., This ratio can be equal to 0.8. For example, FMCW-based OFDM channel estimation techniques can produce approximately 20% ADC sampling gain. The FMCW-based channel estimation scheme described herein can reduce the sampling rate by a relatively large amount compared to OFDM-based channel estimation. For example, when the channel bandwidth 570 is 50 MHz and an FMCW signal is used, the sampling rate used by the receiving device 510 to estimate the OFDM channel 515 at a granularity of four resource blocks 575 can be approximately 1.69% of the sampling rate available to the receiving device 510 when performing OFDM-based channel estimation in the same scenario.

[0118] The FMCW-based OFDM channel estimation described in this paper reliably estimates the frequency-domain OFDM channel 515 using a reduced sampling rate. For example, the accuracy of the FMCW-based OFDM channel estimation technique is relatively similar to that of OFDM-based OFDM channel estimation techniques using a frequency-domain reference signal when compared to a reference value, across a range of packet delay protocols, SCS values, and bandwidths. In other words, the FMCW-based OFDM channel estimation maintains or improves the accuracy and reliability of estimating the frequency-domain OFDM channel 515 while reducing processing and power consumption.

[0119] The receiving device 510 can thereby estimate the frequency-domain OFDM channel 515 using time-domain signal processing and with granularity based on the FMCW signal 525 received at the receiving device 510 and the FMCW signal 530 generated by the receiving device 510. The described FMCW-based OFDM channel estimation technique can be performed by the receiving device 510 in the time domain using time-domain signal processing. That is, when using the FMCW signal to estimate the frequency-domain OFDM channel 515, the receiving device 510 can avoid applying FFT or other frequency transforms. By performing OFDM channel estimation in the time domain, the receiving device 510 can reduce processing complexity, latency, and power consumption compared to other OFDM channel estimation techniques performed at least partially in the frequency domain (e.g., using FFT). Additionally or alternatively, the receiving device 510 can use narrowband radio frequency processing to estimate the frequency-domain OFDM channel 515. In other words, the FMCW signal 525 received at the receiving device 510 can be a broadband signal in radio frequency, and the combined and filtered FMCW signal 540 after LPF 560 can be a narrowband signal for baseband processing.

[0120] In some examples, receiving device 510 may select one or more bandwidth portions (BWPs) (e.g., BWPs with higher channel quality than those configured for receiving device 510) from a set of BWPs associated with (e.g., wideband) and / or included within bandwidth 570, based on an FMCW-based OFDM channel estimation. For example, using an FMCW-based OFDM channel estimation of OFDM channel 515, receiving device 510 may (e.g., from a single FMCW signal, such as FMCW signal 525) identify one or more BWPs within bandwidth 570 that are associated with higher channel quality compared to other BWPs within bandwidth 570. Receiving device 510 may send an indication of one or more second BWPs to transmitting device 505 or network node 110 via a report.

[0121] The transmitting device 505 or network node 110 can receive the report and can configure the receiving device 510 to communicate via at least one of one or more BWPs selected by the receiving device 510. In other words, the transmitting device 505 or network node 110 can select at least one BWP from one or more BWPs indicated by the report. The transmitting device 505 or network node 110 can send control signals (e.g., RRC signals, MAC control element (MAC-CE) signals, and / or downlink control information (DCI) signals) to the receiving device 510 indicating the at least one BWP. Therefore, the receiving device 510 can switch to the at least one BWP (e.g., one or more preferred BWPs).

[0122] As indicated above, Figure 5 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 5 The examples described are different.

[0123] Figure 6 This is a diagram of example 600 associated with a radio frequency architecture for different waveform types according to this disclosure.

[0124] like Figure 6 As shown, a wireless communication device (e.g., UE 120, network node 110, or another wireless communication device) may include a first transmitter 602, a second transmitter 604, a first receiver 606, and / or a second receiver 608. The first transmitter 602 may be a digital transmitter. A transmitter may be or may include a transmission chain.

A receiver may be or may include a receive chain. A receive chain may include one or more radio frequency components (e.g., an RFFE component) configured to receive and / or process received signals. In some examples, the terms "transmitter," "transmission chain," and / or "transmission architecture" are used interchangeably herein. In some examples, the terms "receiver," "receive chain," and / or "receive architecture" are used interchangeably herein. In some aspects, one or more components of a transmitter (e.g., the first transmitter 602 and / or the second transmitter 604) may be combined as described above. Figure 2 The described transmit processor 264, TX MIMO processor 266, modem 254, and / or controller / processor 280 are implemented therein.

Figure 2 Implemented in the described receiver processor 258, MIMO detector 256, modem 254 and / or controller / processor 280.

[0125] The first transmitter 602 may be configured to generate a signal using digital domain processing (e.g., it may be a digital transmitter). In some examples, the first transmitter 602 may be configured to be used in conjunction with other parts of this document (such as in combination with...). Figure 4 The OFDM signal is generated in a similar manner to that described in the previous section. The first transmitter 602 may include a Discrete Fourier Transform (DFT) component 610, a frequency domain (FD) spectrum shaping component 612, an iFFT component 614, a parallel-to-serial (P / S) converter 616, a cyclic prefix (CP) addition component 618, a DAC 620, and / or a mixer 622, etc. For example, the signal... x (t) can be input to DFT component 610 to perform DFT operations. FD spectrum shaping component 612 can be configured to obtain N Parallel data streams and N A parallel data stream is mapped to N At each constellation point. Therefore, the FD spectrum shaping component 612 can output... N 614 parallel symbol streams, each symbol stream corresponding to (iFFT) component 614. N One of the orthogonal subcarriers. These N A parallel symbol stream is represented in the frequency domain and can be converted by the iFFT component 614. N A parallel time-domain sample stream. N A parallel time-domain sample stream can be converted into an OFDM symbol stream by a P / S converter 616. A CP adding component 618 can add or insert CPs into each OFDM symbol stream. A DAC 620 can convert the digital OFDM symbol stream into an analog symbol stream. The analog symbol stream can be up-converted to the desired transmission frequency by an RFFE (e.g., via mixer 622). f c Frequency band. One or more antennas can transmit the obtained signal (e.g., broadband signal and / or OFDM signal).

[0126] The second transmitter 604 can be configured to generate a signal using analog domain processing (e.g., the second transmitter 604 can be an analog transmitter). The second transmitter 604 can be configured to generate an FMCW signal. For example, the second transmitter 604 can be combined with... Figure 5 The described transmitting device 505 generates a signal in a similar manner (e.g., using a VCO 624). One or more antennas can transmit the resulting signal (e.g., a broadband signal or an FMCW signal).

[0127] The first receiver 606 may be configured to process the received signal in the digital domain (e.g., the first receiver 606 may be a digital receiver). For example, the first receiver 606 may be configured to receive and / or process OFDM signals. The first receiver 606 may include a mixer 626, an LPF 628, an ADC 630, a CP removal component 632, a serial-to-parallel (S / P) converter 634, an FFT component 636, and / or a channel estimation component 638, etc. The signal may be received by one or more antennas of the first receiver 606. The received signal may be down-converted to a baseband signal by an RFFE (e.g., via mixer 626, LPF 628, and / or ADC 630). The CP may be removed from the received signal via the CP removal component 632. The baseband signal may be provided to the S / P converter 634. For example, the baseband signal may include an OFDM symbol stream, and the S / P converter 634 may divide the OFDM symbol stream into... N A parallel time-domain symbol stream. N Each of the parallel time-domain symbol streams can correspond to... N One orthogonal subcarrier among orthogonal subcarriers. The FFT component 636 can... N A parallel time-domain symbol stream is converted to the frequency domain and output. N A parallel frequency domain symbol stream. The channel estimation component 638 can use the frequency domain symbol stream to combine with other parts of this paper (such as...). Figure 4 Channel estimation is performed on the wireless channel in a manner similar to that described in the previous section.

[0128] The second receiver 608 may be configured to process the received signal in the analog domain (e.g., the second receiver 608 may be an analog receiver). For example, the second receiver 608 may be configured to be used in conjunction with other parts of this document (such as in combination). Figure 5 The second receiver 608 may receive and / or process FMCW signals in a manner similar to that described in receiving device 510 (e.g., the second receiver 608 may be an FMCW receiver). For example, the second receiver 608 may include a VCO 640 (e.g., configured to generate a local FMCW signal), a mixer 642 (e.g., for combining the received signal and the local FMCW signal), an LPF 644, an ADC 646, and / or a symbol timing alignment component 648, etc. After combining and filtering these signals, the second receiver 608 may perform frequency-domain OFDM channel estimation based on sampling the combined and filtered signal using time-domain signal processing. The second receiver 608 may use the ADC 646 to sample the combined and filtered signal in the time domain.

[0129] like Figure 6As shown, in some examples, a transmitter (e.g., a first transmitter 602 or a second transmitter 604) may transmit signals via a wireless channel, and a receiver (e.g., a first receiver 606 or a second receiver 608) may receive signals via a wireless channel. For example, as indicated by reference numeral 650, a first transmitter 602 may transmit via a wireless channel and a first receiver 606 may receive signals via a wireless channel. As another example, as indicated by reference numeral 652, a first transmitter 602 may transmit via a wireless channel and a second receiver 608 may receive signals via a wireless channel. This example can save processing overhead for downlink signals (e.g., enabling network node 110 to use a digital transmitter while enabling UE 120 to use the second receiver 608, thus saving processing and / or power resources). As another example, as indicated by reference numeral 654, a second transmitter 604 may transmit via a wireless channel and a second receiver 608 may receive signals via a wireless channel. This example can save processing overhead for sensing operations (e.g., enabling both the transmitting and receiving devices to use analog domain processing and / or time domain processing of the signal to save processing and / or power resources). As another example, as shown by reference numeral 656, the second transmitter 604 can transmit via a wireless channel and the first receiver 606 can receive the signal via a wireless channel. This example can save processing overhead for uplink signals (e.g., enabling network node 110 to use a digital receiver while enabling UE 120 to use the second transmitter 604 to save processing and / or power resources).

[0130] In some examples, the wireless communication device may include either a first transmitter 602 or a second transmitter 604. In other examples, the wireless communication device may include both a first transmitter 602 and a second transmitter 604. In such examples, the wireless communication device may be able to switch between transmitting signals using the first transmitter 602 and transmitting signals using the second transmitter 604. In some examples, the wireless communication device may be either a first receiver 606 or a second receiver 608. In other examples, the wireless communication device may include both a first receiver 606 and a second receiver 608. In such examples, the wireless communication device may be able to switch between receiving signals using the first receiver 606 and receiving signals using the second receiver 608.

[0131] As described elsewhere in this document, the second receiver 608 may use a lower sampling rate than the first receiver 606. For example, for a 100 MHz bandwidth and 30 kHz SCS, the number of samples per symbol may be 4,096 (e.g., for the first receiver 606). This could result in the first receiver 606 using a sampling rate of 122.88 MHz (e.g., for the ADC 630). However, in the same scenario, the second receiver 608 may use a sampling rate of 8.19 MHz (e.g., for the ADC 646) (e.g., assuming a channel estimation granularity of one (1) resource block). As another example, for a 400 MHz bandwidth and 30 kHz SCS, the number of samples per symbol may be 16,384 (e.g., for the first receiver 606). This could result in the first receiver 606 using a sampling rate of 491.52 MHz. However, in the same scenario, the second receiver 608 may use a sampling rate of 32.76 MHz. As another example, for a 400MHz bandwidth and 120kHz SCS, the number of samples per symbol could be 4,096 (e.g., for the first receiver 606). This would result in the first receiver 606 using a sampling rate of 491.52MHz. However, in the same scenario, the second receiver 608 could use a sampling rate of 32.76MHz. As another example, for a 1600MHz bandwidth and 120kHz SCS, the number of samples per symbol could be 16,384 (e.g., for the first receiver 606). This would result in the first receiver 606 using a sampling rate of 1966.08MHz. However, in the same scenario, the second receiver 608 could use a sampling rate of 131.04MHz. In some cases, the second receiver 608 can be enabled to use a sampling rate (e.g., for the ADC 646) that is approximately 6.67% of the sampling rate used by the first receiver 606 (e.g., for the ADC 630). Therefore, using the second receiver 608 to measure the wireless channel saves power resources for wireless communication devices compared to using the first receiver 606 to measure the wireless channel.

[0132] For example, to combine with Figure 5Measuring wireless channels in a similar manner to that described (e.g., describing FMCW-based channel estimation) can be beneficial. In some examples, wireless communication devices may use analog receivers (such as the second receiver 608) to measure interference on OFDM channels. However, using analog receivers and / or FMCW-based receivers to measure interference on OFDM channels may introduce one or more problems (e.g., these problems may not exist for FMCW-based channel estimation on OFDM channels). For example, for FMCW-based channel estimation, transmitting and receiving devices may be configured and / or instructed to use one or more parameters to generate FMCW signals (e.g., for transmission or local use at the receiving device for FMCW-based channel estimation). However, for interference measurement, different devices may use different waveforms and / or different parameters to transmit different signals for measurement by the receiving device. For example, to measure interference on a wireless channel, the receiving device may measure signals transmitted by devices from neighboring cells and / or devices within the same cell using different waveforms and / or different transmission parameters. Therefore, it may be difficult to identify the parameters that the receiving device is capable of performing interference measurements (e.g., because it may be difficult to predict the waveform type and / or parameters of the signal measured by a receiving device that uses an analog receiver or an FMCW receiver to measure interference in an OFDM channel).

[0133] As indicated above, Figure 6 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 6 The examples described are different.

[0134] Figure 7 This is a diagram illustrating example 700 related to broadband interference measurements according to this disclosure. Figure 7 As shown, network node 110 (e.g., base station, CU, DU, and / or RU) can communicate with UE 120. In some aspects, network node 110 and UE 120 can be part of a wireless network (e.g., wireless network 100). UE 120 and network node 110 can... Figure 7 The operation shown has been performed after a wireless connection has been established.

[0135] In some respects, UE 120 may be a narrowband UE. For example, UE 120 may support communication via the OFDM channel using frequency domain resources less than the total bandwidth of the OFDM channel. This narrowband may be associated with the baseband capability of UE 120. For example, the OFDM channel may be associated with a bandwidth comprising a set of subbands and / or a set of bandwidth portions. UE 120 may support communication via one or more subbands and / or one or more bandwidth portions, but may not support communication via the total bandwidth of the OFDM channel.

[0136] In some aspects, UE 120 may include one or more receivers (e.g., one or more receive chains and / or one or more receiver architectures). UE 120 may include receivers associated with analog domain processing and / or time domain processing of received signals (e.g., such as a second receiver 608). For example, UE 120 may include receivers configured to receive FMCW signals (e.g., such as a second receiver 608). Receivers associated with analog domain processing and / or time domain processing and / or receivers configured to receive FMCW signals may be referred to as "FMCW-based receivers" or "FMCW-based receiver architectures," etc. For example, the FMCW-based receiver of UE 120 may include one or more VCOs, one or more LPFs, and / or ADCs, etc. In some aspects, UE 120 may be configured to receive and / or measure signals via an OFDM channel using an FMCW-based receiver. For example, as described in more detail elsewhere herein, UE 120 may use an FMCW-based receiver to receive and / or process signals transmitted via an OFDM channel.

[0137] As indicated by reference numeral 705, UE 120 can send and network node 110 can receive capability reports. UE 120 can send capability reports via capability signaling, UE Assisted Information (UAI) communication, RRC signaling, uplink MAC-CE signaling, uplink control information signaling, physical uplink control channel (PUCCH), and / or physical uplink shared channel (PUSCH). Capability reports can indicate whether UE 120 supports one or more operations described herein. For example, capability reports can indicate one or more capability parameters. In some aspects, one or more capability parameters can be information elements indicating whether UE 120 supports a given feature or operation. In some aspects, the one or more capability parameters can be associated with broadband interference measurements on OFDM channels.

[0138] Additionally or alternatively, the one or more capability parameters may be associated with the support subband size for the OFDM channel. The support subband size for the OFDM channel may be the supporting (e.g., maximum) frequency domain range for communication via the OFDM channel. In some aspects, the support subband size for the OFDM channel may be based on the baseband processing capabilities of the UE 120 (e.g., for the digital receiver and / or OFDM-based receiver of the UE 120).

[0139] For example, a capability report may indicate whether UE 120 supports and / or includes an FMCW-based receiver (e.g., capability parameters may indicate that UE 120 supports FMCW-based reception, analog domain processing of the received signal, and / or time domain processing of the received signal for channel measurement). In some aspects, the capability report may indicate whether UE 120 supports using an FMCW-based receiver to measure OFDM channels. In some aspects, the capability report may indicate whether UE 120 supports using an FMCW-based receiver to measure interference associated with OFDM channels (e.g., the capability report may indicate whether UE 120 supports an FMCW Rx architecture for measuring OFDM interference). For example, one or more capability parameters may indicate that the UE supports broadband interference measurement of OFDM channels using an FMCW-associated receive chain.

[0140] In some aspects, the capability report may indicate one or more capability parameters associated with measurements (e.g., interference measurements) performed by an FMCW-based receiver on an OFDM channel. For example, the one or more capability parameters may indicate the supported broadband bandwidth for broadband interference measurements. As used herein, “broadband interference measurement” may refer to an interference measurement performed using a broadband receiver (e.g., configured to measure and / or process the full bandwidth of the channel). In some aspects, “broadband interference measurement” may refer to an interference measurement performed by a device on a band or bandwidth of the channel that is greater than the supported bandwidth for communication (e.g., data communication and / or control communication) via the channel by the device. For example, UE 120 may support a first bandwidth for data or control communication via an OFDM channel and a second bandwidth for FMCW-based interference measurements on the OFDM channel, wherein the second bandwidth is greater than the first bandwidth. In some aspects, UE 120 may use an FMCW-based receiver to perform broadband interference measurements on the OFDM channel (e.g., by measuring the OFDM channel in a manner similar to that of the second receiver 608). For example, a capability parameter may indicate the maximum supported broadband bandwidth (e.g., for OFDM channels) that can be measured using the FMCW receive architecture of the UE 120. In some aspects, the capability report may indicate a first (maximum) supported broadband bandwidth for interference measurements of the OFDM channel and / or a second (maximum) supported broadband bandwidth for channel estimation measurements of the OFDM channel using the FMCW receive architecture. The first and second supported broadband bandwidths may be the same or different.

[0141] In some aspects, the one or more capability parameters indicate the supported analog-to-digital sampling rate (e.g., the ADC for the FMCW-based receiver of UE 120) used for broadband interference measurements. For example, the capability report may indicate the maximum supported ADC sampling rate that can be used in the FMCW receiver architecture of UE 120. For example, one or more ADC sampling rate levels may be defined or otherwise fixed (e.g., by network node 110 and / or by wireless communication standards such as 3GPP). UE 120 may select an ADC sampling rate level from the one or more ADC sampling rate levels (e.g., the highest sampling rate level from the one or more ADC sampling rate levels, which is also less than the maximum supported ADC sampling rate of the FMCW receiver architecture of UE 120). The one or more capability parameters may indicate the selected ADC sampling rate level.

[0142] In some aspects, the one or more capability parameters include the granularity of supported interference measurements for broadband interference measurements. For example, the one or more capability parameters may indicate the minimum granularity of supported interference measurements that can be measured using the FMCW receiver architecture of UE 120. This granularity may be in the form of frequency domain resources and / or subband size. For example, a capability report may indicate that UE 120 is capable of measuring interference using... X MHz wideband (e.g., supporting wideband bandwidth for wideband interference measurements) uses an FMCW-based receiver to perform interference measurements on the OFDM channel and is capable of targeting... X Within MHz broadband bandwidth Y The MHz (e.g., granularity) band size report provides individual interference measurement information. For example, a capability report may indicate that the UE 120 is capable of reporting interference measurements for band sizes greater than or equal to the indicated granularity.

[0143] For example, there may be a relationship between the measured broadband bandwidth, ADC sampling rate, and subband granularity. For instance, the ADC sampling rate can be expressed as... ,in It is the slope of the FMCW signal. It refers to broadband bandwidth. It can represent SCS, and This refers to the sub-band granularity of the measurement. By reporting the supported broadband bandwidth, supported ADC sampling rate, and supported granularity for broadband interference measurements using UE 120, network node 110 can ensure that the configured interference measurement resources and / or the measurement reporting granularity configured by UE 120 are actually supported by UE 120.

[0144] In some aspects, network node 110 may instruct UE 120 to send an indication of one or more timing gaps associated with broadband interference measurement. For example, configuration information may instruct UE 120 to send an indication of one or more minimum timing gaps for broadband interference measurement. In some aspects, the one or more timing gaps may include a first timing gap associated with a first supporting timing gap between receiving configuration information and measuring interference measurement resources. For example, the first timing gap may be associated with a supporting (e.g., minimum) amount of time between CSI-IM scheduling or configuration (or the last OFDM data transmission) and the time associated with CSI-IM resources. For example, the first timing gap may be associated with the amount of time (e.g., Rx handover time) for UE 120 to switch from using an OFDM-based receiver to using an FMCW-based receiver. UE 120 may send, and network node 110 may receive, a first timing gap parameter (e.g., in a capability report) indicating the supporting amount of time for the first timing gap.

[0145] Additionally, the one or more timing gaps may include a second timing gap associated with a supporting timing gap between measuring the IMR (e.g., CSI-IM resource) and transmitting a measurement report. For example, the second timing gap may be associated with a minimum amount of time between CSI-IM transmission (e.g., the time associated with the measured CSI-IM resource) and an FMCW-based interference measurement report. The second timing gap may be based on the amount of time associated with the UE 120 (e.g., using an FMCW-based receiver) performing interference measurements, and on the amount of time the UE 120 switches from using an FMCW-based receiver to using an OFDM-based receiver. The UE 120 may transmit, and the network node 110 may receive, a second timing gap parameter (e.g., in a capability report) indicating the supporting time (e.g., minimum time) of the second timing gap. In some aspects, the UE 120 may indicate a single timing gap parameter (e.g., indicating the minimum time of both the first and second timing gaps). The network node 110 may configure the CSI-IM resource and the transmission of interference measurement reports to ensure that the timing gaps satisfy the supporting timing gaps indicated by the UE 120.

[0146] As indicated by reference numeral 710, network node 110 can send and UE 120 can receive configuration information. In some aspects, UE 120 can receive configuration information via one or more of system information signaling, RRC signaling, one or more MAC-CEs and / or DCIs, etc. In some aspects, configuration information may include indications of one or more configuration parameters for UE 120 to select, and / or explicit configuration information for UE 120 to configure itself, etc.

[0147] In some respects, configuration information may be based on, in response to, or otherwise associated with a capability report (e.g., and / or one or more capability parameters). For example, network node 110 may be configured to perform one or more operations as described herein by instructing UE 120 to support one or more operations based on, in response to, or otherwise associated with a capability report. As an example, configuration information may be based on, in response to, or otherwise associated with a capability report instructing UE 120 to support performing broadband interference measurements by instructing UE 120 to use an FMCW-based receiver to perform broadband interference measurements on the OFDM channel.

[0148] In some aspects, the configuration information may instruct UE 120 to perform wideband interference measurements on the OFDM channel. In other aspects, the configuration information may instruct UE 120 to use an FMCW-based receiver to perform wideband interference measurements on the OFDM channel. For example, the configuration information may instruct UE 120 to use a receiver chain associated with FMCW (e.g., an FMCW-based receiver) to measure the Interference Measurement Resource (IMR). In other aspects, the configuration information may configure the wideband IMR (e.g., without indicating the type of receiver or receiver architecture that UE 120 will use to measure the IMR to obtain wideband interference measurements on the OFDM channel). UE 120 may determine that the IMR is a wideband resource (e.g., the frequency domain resource based on the IMR is greater than the bandwidth of OFDM communication supported by UE 120 for the OFDM channel, or the frequency domain resource based on the IMR is equal to the total bandwidth of the OFDM channel). As used herein, "wideband resource" can refer to a resource associated with a frequency domain resource that is greater than the supported bandwidth for UE 120 to communicate via a channel (e.g., data communication and / or control communication). For example, UE 120 may support narrowband OFDM communication via an OFDM channel (e.g., where the narrowband has a size of one or more subbands based on or equal to the bandwidth of the OFDM channel). UE 120 may determine, based on, in response to, or otherwise associated with the IMR being a wideband resource, that an FMCW-based receiver will be used to perform wideband interference measurements on the OFDM channel (e.g., using an IMR).

[0149] For example, configuration information may indicate IMR configuration. IMR configuration may be or be associated with Channel State Information (CSI) Reference Signal (CSI-RS) resource configuration. IMR configuration may also be referred to as CSI-RS resource configuration for interference management. IMR may be a CSI Interference Measurement (CSI-IM) resource. In some aspects, IMR may be a zero-power (ZP) resource (e.g., a ZP CSI-RS resource for interference management). In other aspects, IMR may be a non-zero-power (NZP) resource (e.g., an NZP CSI-RS resource). For example, configuration information may indicate CSI reporting settings or CSI-RS resource configuration. For example, network node 110 may use CSI reporting settings (e.g., CSI reporting configuration) to configure a set of CSI-RS resources. CSI reporting settings may indicate resources and / or parameters associated with CSI reports to be sent by UE 120 to network node 110. IMR configuration may indicate ZP resources associated with UE 120 performing interference measurements (e.g., resources where network node 110 does not send CSI-RS to UE 120). More specifically, the IMR configuration can indicate the set of CSI-IM resources that will be used to perform interference measurements.

[0150] For example, in Example 600, the IMR configuration indicates the CSI-IM resource set. m This should be used to perform interference measurements. A CSI-IM resource set may include one or more CSI-IM resources. CSI reporting settings can associate each CSI-RS resource with a corresponding CSI-IM resource. More specifically, each CSI-RS resource can be associated with a CSI-IM resource in terms of resource availability through the ordering of the CSI-RS resource and its corresponding CSI-IM resource within the corresponding resource set. In this respect, the number of CSI-RS resources indicated by the CSI reporting settings may be equal to the number of CSI-IM resources indicated by the CSI reporting settings. Furthermore, CSI-RS resources and associated CSI-IM resources may occur within the same time slot.

[0151] For example, configuration information may indicate the configuration of CSI-IM resources (e.g., in the serving cell of UE 120) used for measuring OFDM interference (e.g., in other cells). CSI-IM resources may be ZP CSI-IM resources. CSI-IM resources may be wideband resources (e.g., associated with frequency domain resources spanning the full bandwidth of the OFDM channel). In some aspects, CSI-IM resources may be configured as periodic resources (e.g., interference measurement resources may be periodic resources). In other aspects, CSI-IM resources may be configured as non-periodic resources (e.g., interference measurement resources may be non-periodic resources). This may trigger UE 120 to report interference measurement results periodically or non-periodically. For example, configuration information (e.g., CSI reporting settings or CSI reporting configuration) may indicate that CSI reports (e.g., indicating wideband interference measurements on the OFDM channel) are configured to be sent periodically by UE 120. In other respects, configuration information (e.g., CSI report settings or CSI report configuration) may indicate that CSI reports are configured to be sent non-periodically by UE 120 (e.g., in response to a request or trigger sent by network node 110).

[0152] For example, configuration information may indicate that the IMR (e.g., a CSI-IM resource) is a periodic resource and that CSI reports (e.g., interference measurement reports) will be sent periodically. As another example, configuration information may indicate that the IMR (e.g., a CSI-IM resource) is a periodic resource and that CSI reports (e.g., interference measurement reports) will be sent aperiodically. As yet another example, configuration information may indicate that the IMR (e.g., a CSI-IM resource) is a non-periodic resource and that CSI reports (e.g., interference measurement reports) will be sent aperiodically.

[0153] In some respects, network node 110 may determine that multiple UEs (e.g., including UE 120) will be configured using an IMR (e.g., the same CSI-IM resource). For example, the CSI-IM resource could be a ZP CSI-IM resource. Therefore, network node 110 can configure multiple UEs using the same CSI-IM (e.g., because network node 110 does not actually use the CSI-IM resource for transmission). For example, the IMR (e.g., CSI-IM) configured for UE 120 may be associated with multiple UEs. Multiple UEs can each use the CSI-IM resource to measure interference on the OFDM channel (e.g., interference caused by transmissions from other cells), as described in more detail elsewhere herein. This improves network resource utilization because network node 110 configures a single resource to enable multiple UEs to perform wideband interference measurements on the OFDM channel (e.g., instead of configuring a separate CSI-IM resource for each UE). In other words, the CSI-IM resource can be reused for multiple UEs to improve the resource utilization efficiency of the wireless network.

[0154] In some aspects, the configuration information may indicate the subband size associated with interference measurements of the OFDM channel. The subband size may be the measurement granularity. For example, the configuration information may indicate that interference measurement results will be reported for one or more subbands (e.g., where the one or more subbands are associated with corresponding reported interference measurement values). In some aspects, the configuration information may indicate the subband (e.g., within the bandwidth of the OFDM channel) that the UE 120 will report its interference measurement information for. For example, the configuration information may indicate one or more subbands used for interference measurements of the OFDM channel (e.g., whose interference measurement information will be included in the interference measurement report) and / or the subband size. The one or more subbands may not overlap in the frequency domain. In some aspects, the one or more subbands may overlap in the frequency domain.

[0155] For example, an IMR (e.g., a CSI-IM resource) may be associated with one or more subbands, and interference measurement information (e.g., sent by UE 120 as described elsewhere herein) may indicate one or more measurements in a corresponding subband within those one or more subbands (e.g., configuration information may instruct UE 120 to report interference measurements to network nodes in a per-subband average manner). In some aspects, the interference measurement of a subband may be an average interference measurement of the subband.

[0156] In some aspects, configuration information may indicate one or more time-domain resources (e.g., one or more symbols, one or more time slots, and / or one or more other time-domain resources) associated with an IMR (e.g., a CSI-IM resource). For example, UE120 may be indicated to have one or more symbols (e.g., one or more OFDM symbols) for wideband interference measurements of the OFDM channel. In other words, configuration information (e.g., configuration of CSI-IM resources) may indicate one or more OFDM symbols during which UE120 will perform wideband interference measurements of the OFDM channel. In some aspects, configuration information may indicate that UE120 will report one or more measurements of the corresponding time-domain resources among the one or more time-domain resources. For example, configuration information may indicate that UE120 will report interference measurements for each of the one or more symbols configured for the CSI-IM resource (e.g., UE120 may be configured to report interference measurements per symbol). In other aspects, configuration information may indicate that UE120 will report measurements of one or more time-domain resources (e.g., the average interference measurement of all symbols configured for the one or more symbols of the CSI-IM resource).

[0157] In some respects, the configuration information may instruct UE 120 to report one or more interference measurements. For example, the configuration information may instruct UE 120 to send an indication of one or more interference plus noise values ​​(e.g., one or more signal-to-interference-plus-noise ratio (SINR) values). Additionally or alternatively, the configuration information may instruct UE 120 to send an indication of one or more subbands. UE 120 may select these one or more subbands based on, in response to, or otherwise associated with interference measurements on the OFDM channel. For example, the one or more subbands may be associated with the lowest interference measurement value. Additionally or alternatively, the one or more subbands may be associated with interference measurements that do not meet an interference threshold. In other words, UE 120 may send an indication of one or more subbands associated with low-measurement interference in the OFDM channel (e.g., which may be commonly referred to as UE 120's "preferred" subbands).

[0158] UE 120 can configure itself at least in part based on configuration information. In some respects, UE 120 can be configured to perform one or more of the operations described herein, at least in part based on configuration information.

[0159] As shown by reference numeral 715, UE 120 can perform interference measurements using an analog receiver (e.g., an FMCW-based receiver) via an IMR (e.g., CSI-IM resource) configured for UE 120. In some aspects, UE 120 can (e.g., based on receive configuration information) measure the configured interference measurement resources to obtain interference measurement information associated with the OFDM channel. For example, UE 120 can use an FMCW-based receiver to measure interference on the OFDM channel (e.g., using resources associated with the CSI-IM resource). In some aspects, UE 120 can (e.g., using an FMCW-based receiver) perform broadband interference measurements on the OFDM channel. For example, UE 120 can use an FMCW-based receiver to perform interference estimation for data OFDM symbols. In some respects, UE 120 may measure the interference measurement resource based on, in response to, or otherwise associated with (e.g., from network node 110) receiving a trigger for measuring the interference measurement resource (e.g., CSI-IM resource) (e.g., included in communications such as MAC-CE communications or DCI communications) (e.g., where the interference measurement resource is configured as an aperiodic resource).

[0160] As an example, UE 120 can use an FMCW-based receiver to estimate the received signal associated with the IMR (e.g., CSI-IM resource). For example, UE 120 can use an FMCW-based receiver to receive a wideband signal. UE 120 can generate a local FMCW signal (e.g., based on the estimated signal received via the channel, which may be a low-power signal or no signal). UE 120 can combine the received signal with the locally generated FMCW signal and provide the combined signal to the LPF (e.g., to generate a narrowband signal from the received wideband signal in the time domain). Therefore, (e.g., compared to UE 120 using a digital receiver to measure interference in the OFDM channel) the sampling rate of the ADC used for the FMCW-based receiver (e.g., for measuring interference in the OFDM channel) can be reduced. UE 120 can measure the energy level or power spectral density (PSD) associated with the CSI-IM resource based on the time-domain processing of the received signal.

[0161] Therefore, UE 120 can estimate and / or measure interference on the OFDM channel that may be caused by transmissions from other cells. Transmissions from other cells can be FMCW signal transmissions and / or OFDM-based transmissions. By estimating the received signal at the FMCW-based receiver and obtaining the PSD of the CSI-IM resource, UE 120 can estimate the interference on the OFDM channel (e.g., regardless of the waveform type of the signal causing the interference). Additionally, UE 120 can obtain interference measurement information for all frequency domain resources in the CSI-IM resource in a single measurement (e.g., instead of obtaining it in multiple measurements and / or multiple samples, as might be the case when UE 120 uses a digital receiver with a baseband capability smaller than the frequency domain size of the CSI-IM resource). This reduces the latency associated with obtaining interference measurement information for the OFDM channel. Additionally, this can save UE 120 power when performing interference measurements on the OFDM channel. Figure 8 The estimated interference using the OFDM channel based on FMCW receiver measurements is described in more detail.

[0162] In some aspects, UE 120 can estimate interference measurements (e.g., SINR) for one or more subbands associated with CSI-IM resources. In some aspects, UE 120 can estimate the average interference measurement for a given subband. In some aspects, UE 120 can estimate the average interference measurement for a given subband during a given OFDM symbol. In other aspects, UE 120 can estimate the average interference measurement for a given subband across multiple OFDM symbols.

[0163] As shown by reference numeral 720, UE 120 can determine one or more subbands based on broadband interference measurements. For example, UE 120 can select one or more subbands based on broadband interference measurements. As an example, UE 120 can select one or more subbands associated with the lowest interference measurement value from a set of subbands associated with CSI-IM resources. As another example, UE 120 can select a single subband associated with the lowest interference measurement value. As yet another example, UE 120 can select one or more subbands associated with interference measurements that meet an interference threshold. In other words, UE 120 can determine the subbands in the bandwidth of the OFDM channel that are associated with a low (or lowest) interference level observed by UE 120.

[0164] In some respects, as indicated by reference numeral 725, network node 110 may send and UE 120 may receive triggers for interference measurement reports (e.g., CSI reports associated with interference management). For example, network node 110 may send the trigger based on the fact that the interference measurement report is an aperiodic measurement report. The trigger may be included in MAC-CE communications and / or DCI communications, etc. The trigger may cause UE 120 to generate and / or send interference measurement reports, as described elsewhere herein.

[0165] As indicated by reference numeral 730, UE 120 may transmit and network node 110 may receive interference measurement reports. For example, UE 120 may transmit and network node 110 may receive measurement reports indicating interference measurement information (e.g., obtained by UE 120 based on measurement broadband interference measurement resources, as described in more detail elsewhere herein). The interference measurement report may be a CSI report. The interference measurement report may indicate one or more interference measurements for a corresponding subband of an OFDM channel. For example, the interference measurement report may indicate the average interference measurement value for a given subband during a given OFDM symbol. In other aspects, the interference measurement report may indicate the average interference measurement value for a given subband across multiple OFDM symbols. In some aspects, the interference measurement report may indicate one or more subbands determined and / or selected by UE 120 (e.g., as described above).

[0166] Network node 110 may perform one or more actions based on, in response to, or otherwise associated with an interference measurement report. For example, network node 110 may determine and / or (e.g., to UE 120) indicate subbands for communication (e.g., OFDM communication) between network node 110 and UE 120 via an OFDM channel. For example, network node 110 may determine subbands of the OFDM channel associated with relatively low interference (e.g., as observed and / or measured by UE 120). Network node 110 may send, and UE 120 may receive, an indication to use the subbands for OFDM communication between UE 120 and network node 110.

[0167] As indicated above, Figure 7 This is provided as an example. Other examples may be provided relative to... Figure 7 The examples described are different.

[0168] Figure 8 This is a diagram of Example 800 related to broadband interference measurement according to this disclosure. Figure 8 Broadband interference measurement resources are described (e.g., by UE 120 in conjunction with other parts of this document, such as...). Figure 7 A more detailed description is given, similar to the method used to perform the estimation of the disturbance level plot. For example, Figure 8The estimated interference level described herein may be for an OFDM channel (e.g., one or more OFDM symbols) obtained by UE 120 using an analog receiver (such as an FMCW-based receiver). For example, UE 120 may use time-domain processing of the estimated signal to an interference measurement resource (e.g., a CSI-IM resource) to estimate the PSD (e.g., measured in dBm) of the received signal across a wideband frequency range.

[0169] like Figure 8 As shown, UE 120 can obtain frequency domain measurement information across a wide frequency range using an analog receiver and / or an FMCW-based receiver (e.g., as described in more detail elsewhere herein). For example, UE 120 can obtain the PSD of the received signal across a wide frequency range. This allows UE 120 to identify sub-bands (e.g., portions of the wide frequency range) associated with lower interference levels while also using a relatively low ADC sampling rate. For example, UE 120 can identify a first sub-band 805 associated with a relatively low interference level (e.g., because the PSD on the first sub-band 805 is lower compared to the PSD of the rest of the wide frequency range). Additionally, UE 120 can identify a second sub-band 810 associated with a relatively high interference level (e.g., because the PSD on the second sub-band 810 is higher compared to the PSD of the rest of the wide frequency range). UE 120 can estimate the interference plus noise level of a given sub-band based on the measured PSD on that sub-band.

[0170] As an example, UE 120 may determine that the first subband 805 is a "preferred" subband due to its relatively low interference level. Additionally, UE 120 may determine that the second subband 810 should not be used for OFDM communication due to its relatively high interference level. For example, UE 120 may indicate the first subband 805 (e.g., as a "preferred" subband) in its interference measurement report. UE 120 may (e.g., in its interference measurement report) indicate that the second subband 810 should not be used. UE 120 may determine the interference measurement value for each subband based on the PSD value measured by UE 120.

[0171] As indicated above, Figure 8 This is provided as an example. Other examples may be provided relative to... Figure 8 The examples described are different.
