[0001] Cross - reference to related applications

[0002] This patent application claims priority to U.S. Non - Provisional Patent Application No. 18 / 050,844, filed on October 28, 2022, entitled "USER EQUIPMENT (UE) - TO - UE CROSS LINK INTERFERENCE REPORTING", and assigned to the assignee of the present application. The disclosure of the prior application is considered to be a part of this patent application and is incorporated herein by reference. Technical field

[0003] Aspects of the present disclosure generally relate to wireless communication and relate to techniques and apparatuses for user equipment (UE) - to - UE cross - link interference reporting. Background art

[0004] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasting. A typical wireless communication system may employ multiple access techniques capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access techniques 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 / Advanced LTE is an enhanced set of the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the 3rd Generation Partnership Project (3GPP).

[0005] A wireless network may include one or more network nodes that support communication for wireless communication devices such as user equipment (UE) or multiple UEs. A UE may communicate with a network node via downlink communication and uplink communication. "Downlink" (or "DL") refers to the communication link from the network node to the UE, and "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 a local link (e.g., sidelink (SL), Wireless Local Area Network (WLAN) link, and / or Wireless Personal Area Network (WPAN) link, etc.).

[0006] The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different UEs to communicate at the urban, national, regional, and / or global levels. New Radio (NR) (which may be referred to as 5G) is an enhanced set of the LTE mobile standard promulgated by 3GPP. NR is designed to improve spectral efficiency, reduce costs, enhance services, utilize new spectra, and better integrate with other open standards by using Orthogonal Frequency Division Multiplexing (OFDM) with Cyclic Prefix (CP) (CP-OFDM) on the downlink, CP-OFDM and / or Single Carrier Frequency Division Multiplexing (SC-FDM) (also known as Discrete Fourier Transform Spread OFDM (DFT-s-OFDM)) on the uplink, and supporting beamforming, Multiple Input Multiple Output (MIMO) antenna technology, and carrier aggregation, thereby better supporting mobile broadband Internet access. With the continuous increase in the demand for mobile broadband access, further improvements to LTE, NR, and other radio access technologies remain useful. SUMMARY OF THE INVENTION

[0037] Aspects of the present disclosure are described more fully hereinafter with reference to the accompanying drawings. However, the present disclosure may be embodied in many different forms and should not be construed as limited to any specific structure or function presented throughout this disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art. Those skilled in the art should understand that the scope of the present disclosure is intended to cover any aspect of the present disclosure disclosed herein, whether implemented independently of or in combination with any other aspect of the present disclosure. For example, any number of the aspects set forth herein may be used to implement an apparatus or practice a method. In addition, the scope of the present disclosure is intended to cover such apparatus or methods implemented using other structures, functions, or a combination of structures and functions in addition to or different from the aspects of the present disclosure set forth herein. It should be understood that any aspect of the present disclosure disclosed herein may be embodied by one or more elements of the claims.

[0038] Several aspects of a telecommunications system will now be presented with reference to various apparatuses and techniques. These apparatuses and techniques will be described in the following detailed description and illustrated in the drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements may be implemented using hardware, software, or a combination thereof. Whether these elements are implemented as hardware or software depends on the particular application and design constraints imposed on the overall system.

[0039] Although terms generally associated with 5G or New Radio (NR) radio access technology (RAT) may be used herein to describe aspects, aspects of the present disclosure may be applied to other RATs, such as 3G RAT, 4G RAT, and / or post-5G RAT (e.g., 6G).

[0040] Figure 1FIG. is an illustration of an example of a wireless network 100 in accordance with the present disclosure. The wireless network 100 may be a 5G (e.g., NR) network and / or a 4G (e.g., Long Term Evolution (LTE)) network, or may include elements of a 5G (e.g., NR) network and / or elements of a 4G (e.g., Long Term Evolution (LTE)) network, among other examples. The wireless network 100 may include one or more network nodes 110 (shown as network nodes 110a, network nodes 110b, network nodes 110c, and network nodes 110d), user equipment (UE) 120 or multiple UEs 120 (shown as UEs 120a, UEs 120b, UEs 120c, UEs 120d, and UEs 120e), and / or other entities. The network nodes 110 are network nodes that communicate with the UEs 120. As shown, the network nodes 110 may include one or more network nodes. For example, the network nodes 110 may be integrated network nodes, which means that the integrated network nodes are configured to utilize a radio protocol stack that is physically or logically integrated within a single radio access network (RAN) node (e.g., within a single device or unit). As another example, the network nodes 110 may be decomposed network nodes (sometimes referred to as decomposed base stations), which means that the network nodes 110 are 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).

[0041] In some examples, the network nodes 110 are or include network nodes that communicate with the UEs 120 via radio access links, such as RUs. In some examples, the network nodes 110 are or include network nodes that communicate with other network nodes 110 via fronthaul links or midhaul links, such as DUs. In some examples, the network nodes 110 are or include network nodes that communicate with other network nodes 110 via midhaul links or communicate with a core network via a backhaul link, such as CUs. In some examples, the network nodes 110 (such as integrated network nodes 110 or decomposed network nodes 110) may include multiple network nodes, such as one or more RUs, one or more CUs, and / or one or more DUs. The network nodes 110 may include, for example, NR base stations, LTE base stations, Node Bs, eNBs (e.g., in 4G), gNBs (e.g., in 5G), access points, transmit receive points (TRPs), DUs, RUs, CUs, mobility elements of the network, core network nodes, network elements, network equipment, RAN nodes, or combinations thereof. In some examples, the network nodes 110 may be interconnected with each other or with one or more other network nodes 110 in the wireless network 100 using any suitable transport network via various types of fronthaul, midhaul, and / or backhaul interfaces, such as direct physical connections, air interfaces, or virtual networks.

[0042] In some examples, the network node 110 may provide communication coverage for a specific geographical 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 the network node 110 and / or the network node subsystem serving that coverage area. The network node 110 may provide communication coverage for macro cells, pico cells, femto cells, and / or another type of cell. A macro cell may cover a relatively large geographical area (e.g., with a radius of several kilometers) and may allow unrestricted access by UEs 120 with a service subscription. A pico cell may cover a relatively small geographical area and may allow unrestricted access by UEs 120 with a service subscription. A femto cell may cover a relatively small geographical area (e.g., a home) and may allow restricted access by UEs 120 associated with the femto cell (e.g., UEs 120 in a Closed Subscriber Group (CSG)). The network node 110 for a macro cell may be referred to as a macro network node. The network node 110 for a pico cell may be referred to as a pico network node. The network node 110 for a femto cell may be referred to as a femto network node or a home network node. In Figure 1 the example shown, the network node 110a may be a macro network node for the macro cell 102a, the network node 110b may be a pico network node for the pico cell 102b, and the network node 110c may be a femto network node for the femto cell 102c. A network node may support one or more (e.g., three) cells. In some examples, a cell may not necessarily be stationary, and the geographical area of the cell may move according to the location of the mobile network node 110 (e.g., a mobile network node).

[0043] In some aspects, the term "base station" or "network node" may refer to a centralized base station, a distributed base station, an integrated access and backhaul (IAB) node, a relay node, or one or more components thereof. For example, in some aspects, a "base station" or "network node" may refer to a CU, a DU, an RU, a near real-time (near-RT) RAN intelligent controller (RIC), or a non-real-time (non-RT) RIC, or a combination thereof. In some aspects, the term "base station" or "network node" may refer to a single device configured to perform one or more functions, such as those described herein in connection 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 at 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 the 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 may be instantiated on a single device. In some aspects, the term "base station" or "network node" may refer to one base station function among base station functions, rather than another base station function. In this way, a single device may include more than one base station.

[0044] Wireless network 100 may include one or more relay stations. A relay station is a network node that can receive a transmission of data from an upstream node (e.g., network node 110 or UE 120) and forward the transmission of data to a downstream node (e.g., UE 120 or network node 110). A relay station may be a UE 120 capable of relaying transmissions for other UEs 120. In Figure 1 the example shown, network node 110d (e.g., a relay network node) may communicate with network node 110a (e.g., a macro network node) and UE 120d to facilitate communication between network node 110a and UE 120d. A network node 110 that relays communication may be referred to as a relay station, a relay base station, a relay network node, a relay node, a repeater, etc.

[0045] Wireless network 100 may be a heterogeneous network that includes different types of network nodes 110, such as macro network nodes, pico network nodes, femto network nodes, relay network nodes, etc. These different types of network nodes 110 may have different transmission power levels, different coverage areas, and / or different impacts on interference in wireless network 100. For example, a macro network node may have a high transmission power level (e.g., 5 watts to 40 watts), while pico network nodes, femto network nodes, and relay network nodes may have lower transmission power levels (e.g., 0.1 watt to 2 watts).

[0046] The network controller 130 can be coupled to or communicate with a set of network nodes 110, and can provide coordination and control for these network nodes 110. The network controller 130 can communicate with the network nodes 110 via a fronthaul communication link or a midhaul communication link. The network nodes 110 can also communicate directly with each other, or indirectly via a wireless fronthaul communication link or a wired fronthaul communication link. In some aspects, the network controller 130 can be a CU or a core network device, or can include a CU or a core network device.

[0047] UEs 120 can be distributed throughout the wireless network 100, and each UE 120 can be stationary or mobile. The UEs 120 can include, for example, access terminals, terminals, mobile stations, and / or subscriber units. The UEs 120 can be cellular phones (e.g., smartphones), personal digital assistants (PDAs), wireless modems, wireless communication devices, handheld devices, laptop computers, cordless phones, wireless local loop (WLL) stations, tablet computers, cameras, gaming devices, netbooks, smartbooks, ultrabooks, medical devices, biometric devices, wearable devices (e.g., smartwatches, smart clothing, smart glasses, smart wristbands, smart jewelry (e.g., smart rings or smart bracelets)), entertainment devices (e.g., music devices, video devices, and / or satellite radios), vehicle components or sensors, smart meters / sensors, industrial manufacturing equipment, global positioning system devices, UE functions of network nodes, and / or any other suitable devices configured to communicate via wireless or wired media.

[0048] Some UEs 120 can be considered machine type communication (MTC) or evolved or enhanced machine type communication (eMTC) UEs. The MTC UEs and / or eMTC UEs can include, for example, robots, drones, remote devices, sensors, meters, monitors, and / or location tags, which can communicate with network nodes, another device (e.g., a remote device), or some other entity. Some UEs 120 can be considered Internet of Things (IoT) devices, and / or can be implemented as narrowband IoT (NB-IoT) devices. Some UEs 120 can be considered customer premises equipment. The UEs 120 can be included inside a housing that houses components of the UE 120, such as processor components and / or memory components. In some examples, the processor components and the memory components can be coupled together. For example, the processor components (e.g., one or more processors) and the memory components (e.g., memory) can be operatively coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0049] 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. The RAT can be referred to as radio technology, air interface, etc. The frequency can be referred to as carrier, frequency channel, etc. In a given geographical area, each frequency can support a single RAT to avoid interference between wireless networks of different RATs. In some cases, an NR or 5G RAT network can be deployed.

[0050] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) can communicate directly using one or more sidelink channels (e.g., communicate with each other without using the network node 110 as an intermediate device). For example, the UE 120 can use peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which can include vehicle-to-vehicle (V2V) protocol, vehicle-to-infrastructure (V2I) protocol, or vehicle-to-pedestrian (V2P) protocol) and / or mesh network to communicate. In such examples, the UE 120 can perform scheduling operations, resource selection operations, and / or other operations described elsewhere in this document as being performed by the network node 110.

[0051] The devices of the wireless network 100 can communicate using the electromagnetic spectrum, which can be subdivided into various categories, bands, channels, etc. according to frequency or wavelength. For example, the devices of the wireless network 100 can communicate using one or more operating bands. In 5G NR, two initial operating bands have been identified as frequency range designations FR1 (410 MHz – 7.125 GHz) and FR2 (24.25 GHz – 52.6 GHz). It should be understood that although a part of FR1 is greater than 6 GHz, in various documents and articles, FR1 is often (interchangeably) referred to as the “sub-6 GHz” band. Regarding FR2, a similar naming issue sometimes occurs, which is usually (interchangeably) referred to as the “millimeter wave” band in documents and articles, although it is different from the extremely high frequency (EHF) band (30 GHz – 300 GHz) identified by the International Telecommunication Union (ITU) as the “millimeter wave” band.

[0052] The frequency between FR1 and FR2 is generally referred to as the mid-band frequency. Recent 5G NR studies have identified the operating bands for these mid-band frequencies as frequency range designations FR3 (7.125 GHz – 24.25 GHz). Bands falling within FR3 can inherit FR1 characteristics and / or FR2 characteristics, and thus can effectively extend the features of FR1 and / or FR2 to the mid-band frequencies. Additionally, higher frequency bands are currently being explored to extend 5G NR operation beyond 52.6 GHz. For example, three higher operating bands have been identified as frequency range designations FR4a or FR4-1 (52.6 GHz – 71 GHz), FR4 (52.6 GHz – 114.25 GHz), and FR5 (114.25 GHz – 300 GHz). Each of these higher frequency bands falls within the EHF band.

[0053] Considering the above examples, unless otherwise specifically stated, it should be understood that if terms such as "below 6 GHz" are used herein, such terms can generally represent frequencies that can be below 6 GHz, can be within FR1, or can include mid-band frequencies. Additionally, unless otherwise specifically stated, it should be understood that if terms such as "millimeter wave" are used herein, such terms can generally represent frequencies that can include mid-band frequencies, can be within FR2, FR4, FR4-a or FR4-1, and / or FR5, or can be within the EHF band. It is contemplated that the frequencies included in these operating bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, and / or FR5) may be modified, and the techniques described herein apply to those modified frequency ranges.

[0054] In some aspects, UE 120 may include a communication manager 140. As described in more detail elsewhere herein, the communication manager 140 may measure the characteristics of a UE-to-UE cross-link interference (CLI) reference signal in an uplink sub-band (SB) of a network node sub-band full-duplex (SBFD) symbol; and transmit a report including information associated with the characteristics of the UE-to-UE CLI reference signal in the uplink SB. Additionally or alternatively, the communication manager 140 may perform one or more other operations described herein.

[0055] In some aspects, UE 120 may include a communication manager 140.

[0059] Figure 2 FIG. 200 is a diagram illustrating an example 200 of communication between network node 110 and UE 120 in a wireless network 100 in accordance with the present disclosure. Network node 110 may be equipped with a set of antennas 234a through 234t, such as T antennas (T≥1). UE 120 may be equipped with a set of antennas 252a through 252r, such as R antennas (R≥1). Network node 110 of example 200 includes one or more radio frequency components, such as antennas 234 and modem 232. In some examples, network node 110 may include an interface, a communication component, or another component that facilitates communication with UE 120 or another network node. Some network nodes 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, transmit processor 220 may receive data destined for UE 120 (or a set of UEs 120) from data source 212. Transmit processor 220 may select one or more modulation and coding schemes (MCSs) for UE 120 based at least in part on one or more channel quality indicators (CQIs) received from UE 120. Network node 110 may process (e.g., encode and modulate) the data for UE 120 based at least in part on the MCS selected for UE 120 and may provide data symbols for UE 120. Transmit processor 220 may process system information (e.g., for semi-static resource allocation information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper layer signaling) and provide overhead symbols and control symbols. Transmit processor 220 may generate reference symbols for reference signals (e.g., cell-specific reference signal (CRS) or demodulation reference signal (DMRS)) and synchronization signals (e.g., primary synchronization signal (PSS) or secondary synchronization signal (SSS)). Transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on the data symbols, control symbols, overhead symbols, and / or reference symbols, if applicable, and may provide a set of output symbol streams (e.g., T output symbol streams) to a corresponding set of modems 232 (e.g., T modems) (shown as modems 232a through 232t). For example, each output symbol stream may be provided to the modulator component (shown as MOD) of modem 232. Each modem 232 may process the corresponding output symbol stream (e.g., for OFDM) using the corresponding modulator component to obtain an output sample stream. Each modem 232 may also process the output sample stream (e.g., convert to analog, amplify, filter, and / or upconvert) using the corresponding modulator component to obtain a downlink signal. Modems 232a through 232t may transmit a set of downlink signals (e.g., T downlink signals) via a corresponding set of antennas 234 (e.g., T antennas) (shown as antennas 234a through 234t).

[0061] At the UE 120, a set of antennas 252 (shown as antennas 252a through 252r) may receive downlink signals from the network node 110 and / or other network nodes 110 and may provide a set of received signals (e.g., R received signals) to a set of modems 254 (e.g., R modems) (shown as modems 254a through 254r). For example, each received signal may be provided to a demodulator component (shown as DEMOD) of the modem 254. Each modem 254 may use the corresponding demodulator component to condition (e.g., filter, amplify, down-convert, and / or digitize) the received signal to obtain input samples. Each modem 254 may use the demodulator component to further process the input samples (e.g., for OFDM) to obtain received symbols. The MIMO detector 256 may obtain the received symbols from the modems 254, may perform MIMO detection on the received symbols if applicable, and may provide the detected symbols. The receive processor 258 may process (e.g., demodulate and decode) the detected symbols, may provide the decoded data for the UE 120 to the data sink 260, and may provide the decoded control information and system information to the controller / processor 280. The term "controller / processor" may refer to one or more controllers, one or more processors, or a combination thereof. The channel processor may determine reference signal received power (RSRP) parameters, received signal strength indicator (RSSI) parameters, reference signal received quality (RSRQ) parameters, and / or CQI parameters, etc. In some examples, one or more components of the UE 120 may be included in the housing 284.

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

[0063] One or more antennas (e.g., antennas 234a through 234t and / or antennas 252a through 252r) may include one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, and / or one or more antenna arrays, etc., or may be included within one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, and / or one or more antenna arrays, etc. The antenna panel, antenna group, set of antenna elements, and / or antenna array may include one or more antenna elements (within a single housing or multiple housings), a set of coplanar antenna elements, a set of non-coplanar antenna elements, and / or one or more antenna elements coupled to one or more transmit and / or receive components (such as Figure 2 one or more components) of

[0064] On the uplink, at the UE 120, the transmit processor 264 may receive and process data from the data source 262 and control information from the controller / processor 280 (e.g., for reports including RSRP, RSSI, RSRQ, and / or CQI). The transmit processor 264 may generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be pre-decoded by the TX MIMO processor 266, where applicable, further processed by the modem 254 (e.g., for DFT-s-OFDM or CP-OFDM), and sent to the network node 110. In some examples, the modem 254 of the UE 120 may include a modulator and a demodulator. In some examples, the UE 120 includes a transceiver. The transceiver may include any combination of an antenna 252, a modem 254, a MIMO detector 256, a receive processor 258, a transmit processor 264, and / or a TX MIMO processor 266. The transceiver may be used by a processor (eg, controller / processor 280) and memory 282 to perform the functions described herein (eg, with reference to Figures 7 to 14 ) or any aspect of any of the methods described herein.

[0065] At the network node 110, uplink signals from the UE 120 and / or other UEs may be received by the antenna 234, processed by the modem 232 (e.g., a demodulator component (shown as DEMOD) of the modem 232), detected by the MIMO detector 236 (where applicable), and further processed by the receive processor 238 to obtain decoded data and control information transmitted by the UE 120. The receive processor 238 may provide the decoded data to the data sink 239 and the decoded control information to the controller / processor 240. The network node 110 may include a communication unit 244 and may communicate with the network controller 130 via the communication unit 244. The network node 110 may include a scheduler 246 to schedule one or more UEs 120 for downlink communication and / or uplink communication. In some examples, the modem 232 of the network node 110 may include a modulator and a demodulator. In some examples, the network node 110 includes a transceiver. The transceiver may include any combination of antenna 234, modem 232, MIMO detector 236, receive processor 238, transmit processor 220, and / or TX MIMO processor 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to perform operations described herein (e.g., with reference to Figures 7 to 14 ) or any aspect of any of the methods described herein.

[0066] The controller / processor 240 of network node 110, the controller / processor 280 of UE 120, and / or Figure 2 any other component of may perform one or more techniques associated with cross-link interference (CLI) reporting, as described in more detail elsewhere herein. For example, the controller / processor 240 of network node 110, the controller / processor 280 of UE 120, and / or Figure 2 any other component of may execute or direct, for example, Figure 9 process 900 of, Figure 10 process 1000 of, Figure 11 process 1100 of, Figure 12 process 1200 of, and / or the operations of other processes as described herein. Memory 242 and memory 282 may store data and program code for network node 110 and UE 120, respectively. In some examples, memory 242 and / or memory 282 may include non-transitory computer-readable media storing one or more instructions for wireless communication (e.g., code and / or program code). For example, when the one or more instructions are executed by one or more processors of network node 110 and / or UE 120 (e.g., executed directly, or after compilation, transformation, and / or interpretation), the one or more processors, UE 120, and / or network node 110 may execute or direct, for example, Figure 9 process 900 of, Figure 10 process 1000 of, Figure 11 process 1100 of, Figure 12 process 1200 of, and / or the operations of other processes as described herein. In some examples, executing the instructions may include running the instructions, transforming the instructions, compiling the instructions, and / or interpreting the instructions, etc.

[0067] In some aspects, UE 120 includes components for measuring characteristics of a UE-to-UE CLI reference signal in an uplink SB of network node SBFD symbols; and / or components for transmitting a report including information associated with the characteristics of the UE-to-UE CLI reference signal in the uplink SB. The components for UE 120 to perform the operations described herein may include, for example, one or more of communication manager 140, antenna 252, modem 254, MIMO detector 256, receive processor 258, transmit processor 264, TX MIMO processor 266, controller / processor 280, or memory 282.

[0068] In some aspects, UE 120 includes components for measuring characteristics of the UE-to-UE CLI reference signal in a first plurality of sub-SBs of a symbol, the first plurality of sub-SBs being included in a first SB of the symbol; and / or for transmitting a report including information associated with the characteristics of the UE-to-UE CLI reference signal in the first plurality of sub-SBs. Components for the UE to perform the operations described herein may include, for example, one or more of the following: communication manager 140, antenna 252, modem 254, MIMO detector 256, receive processor 258, transmit processor 264, TX MIMO processor 266, controller / processor 280, or memory 282.

[0069] In some aspects, network node 110 includes components for sending a configuration to UE 120, the configuration being associated with measuring or reporting characteristics of the UE-to-UE CLI reference signal in an uplink SB of a network node SBFD symbol; and / or for receiving a report from the UE including information associated with the characteristics of the UE-to-UE CLI reference signal in the uplink SB. Components for network node 110 to perform the operations described herein may include, for example, one or more of communication manager 150, transmit processor 220, TX MIMO processor 230, modem 232, antenna 234, MIMO detector 236, receive processor 238, controller / processor 240, memory 242, or scheduler 246.

[0070] In some aspects, network node 110 includes components for sending a configuration to UE 120, the configuration being associated with measuring or reporting characteristics of the UE-to-UE CLI reference signal in a first plurality of sub-SBs of a symbol, the first plurality of sub-SBs being included in a first SB of the symbol; and / or for receiving a report including information associated with the characteristics of the UE-to-UE CLI reference signal in the first plurality of sub-SBs. Components for network node 110 to perform the operations described herein may include, for example, one or more of communication manager 150, transmit processor 220, TX MIMO processor 230, modem 232, antenna 234, MIMO detector 236, receive processor 238, controller / processor 240, memory 242, or scheduler 246.

[0071] Although Figure 2 the boxes are illustrated as different components, the functions described above with respect to these boxes may be implemented in a single hardware, software, or combined component or in various combinations of components. For example, the functions described with respect to transmit processor 264, receive processor 258, and / or TX MIMO processor 266 may be performed by or under the control of controller / processor 280.

[0072] As indicated above, Figure 2 is provided as an example. Other examples may differ from the examples Figure 2 described.

[0073] The deployment of a communication system (such as a 5G NR system) can be arranged with various components or constituent parts in a variety of ways. In a 5G NR system or network, network nodes, network entities, mobility elements of the network, RAN nodes, core network nodes, network elements, base stations, or network equipment can be implemented in an aggregated or disaggregated 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 one or more components) performing base station functionality can be implemented as an aggregated base station (also referred to as a stand-alone base station or monolithic base station) or a disaggregated base station. A "network entity" or "network node" can refer to a disaggregated base station or one or more units of a disaggregated base station (such as one or more CUs, one or more DUs, one or more RUs, or a combination thereof).

[0074] An aggregated base station (e.g., an aggregated network node) can be configured to utilize a radio protocol stack physically or logically integrated within a single RAN node (e.g., within a single device or unit). A disaggregated base station (e.g., a disaggregated network node) can be configured to utilize a protocol stack physically or logically distributed among two or more units (such as one or more CUs, one or more DUs, or one or more RUs). In some examples, a CU can be implemented within a network node, and one or more DUs can be co-located with the CU, or alternatively, can be geographically or virtually spread across one or more other network nodes. A DU can be implemented to communicate with one or more RUs. Each of the CU, DU, and RU can also be implemented as a virtual unit, such as a virtual central unit (VCU), virtual distributed unit (VDU), or virtual radio unit (VRU), etc.

[0075] Base station type operations or network designs can consider the aggregation characteristics of base station functionality. For example, disaggregated base stations can be utilized in an IAB network, an open radio access network (O-RAN (such as a network configuration initiated by the O-RAN Alliance)), or a virtualized radio access network (vRAN, also known as a cloud radio access network (C-RAN)) to facilitate the scaling of a communication system by separating base station functionality into one or more units that can be deployed separately. A disaggregated base station can include functionality implemented across two or more units at various physical locations, as well as functionality implemented virtually for at least one unit, which can achieve flexibility in network design. The individual units of a disaggregated base station can be configured for wired or wireless communication with at least one other unit of the disaggregated base station.

[0076] Figure 3 FIG. is an illustration of an example disaggregated base station architecture 300 in accordance with the present disclosure. The disaggregated base station architecture 300 may include a CU 310 that may communicate directly with a core network 320 via a backhaul link, or indirectly with the core network 320 through one or more disaggregated control units (such as a near RT RIC 325 via an E2 link, or a non-RT RIC 315 associated with a service management and orchestration (SMO) framework 305, or both). The CU 310 may communicate with one or more DUs 330 via a respective midhaul link such as through an F1 interface. Each DU in the DUs 330 may communicate with one or more RUs 340 via a respective fronthaul link. Each RU in the RUs 340 may communicate with one or more UEs 120 via a respective radio frequency (RF) access link. In some embodiments, a UE 120 may be served simultaneously by multiple RUs 340.

[0077] Each unit (including the CU 310, DU 330, RU 340) and the near RT RIC 325, non-RT RIC 315, and SMO framework 305 may include or be coupled to one or more interfaces configured to receive or transmit signals, data, or information (collectively referred to as signals) via a wired or wireless transmission medium. Each unit or an associated processor or controller that provides instructions to one or more communication interfaces of a respective unit may be configured to communicate with one or more of the other units via the transmission medium. In some examples, each unit may include a wired interface configured to receive signals or transmit signals to one or more of the other units via a wired transmission medium, 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 of the other units or both via a wireless transmission medium.

[0078] In some aspects, the CU 310 may host one or more higher layer 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, among others. Each control function may be implemented using an interface that is configured to communicate signals with other control functions hosted by the CU 310. The CU 310 may be configured to handle user plane functionality (e.g., Central Unit - User Plane (CU-UP) functionality), control plane functionality (e.g., Central Unit - Control Plane (CU-CP) functionality), or a combination thereof. In some embodiments, the CU 310 may be logically split into one or more CU-UP units and one or more CU-CP units. When implemented in an O-RAN configuration, the CU-UP units may communicate bidirectionally with the CU-CP units via an interface such as the E1 interface. As needed, the CU 310 may be implemented to communicate with the DU 330 for network control and signaling.

[0079] 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 RUs 340. In some aspects, the DU 330 may host one or more of the Radio Link Control (RLC) layer, the Medium Access Control (MAC) layer, and one or more higher Physical (PHY) layers, at least partially according to a functional split (such as the functional split defined by 3GPP). In some aspects, one or more of the higher PHY layers may be implemented by one or more modules for forward error correction (FEC) encoding and decoding, scrambling, and modulation and demodulation, among others. In some aspects, the DU 330 may also host one or more lower PHY layers, such as those implemented by one or more modules for fast Fourier transform (FFT), inverse FFT (iFFT), digital beamforming, or physical random access channel (PRACH) extraction and filtering, among others. Each layer (which may also be referred to as a module) may be implemented using an interface that is configured to communicate signals with other layers (and modules) hosted by the DU 330 or with control functions hosted by the CU 310.

[0080] Each RU 340 can implement lower layer functionality. In some deployments, the RU 340 controlled by the 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, etc.) based on functional split (such as the functional split defined by 3GPP), such as lower layer functional split. In this architecture, each RU 340 can be operated to handle over-the-air (OTA) communication with one or more UEs 120. In some embodiments, the real-time aspects and non-real-time aspects of communicating with the control plane and user plane of the RU 340 can be controlled by the corresponding DU 330. In some scenarios, this configuration can enable each DU 330 and CU 310 to be implemented in a cloud-based RAN architecture such as a vRAN architecture.

[0081] The SMO framework 305 can be configured to support the deployment and orchestration of RAN for both non-virtualized network elements 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, and these dedicated physical resources can be managed via an operation and maintenance interface (such as the O1 interface). For virtualized network elements, the SMO framework 305 can be configured to interact with a cloud computing platform (such as the Open Cloud (O-Cloud) platform 390) to perform network element lifecycle management (such as instantiating virtualized network elements) via a cloud computing platform interface (such as the O2 interface). Such virtualized network elements can include, but are not limited to, CU 310, DU 330, RU 340, non-RT RIC 315, and near-RT RIC 325. In some embodiments, the SMO framework 305 can communicate with the hardware aspects of the 4G RAN (such as the Open eNB (O-eNB) 311) via the O1 interface. Additionally, in some embodiments, the SMO framework 305 can communicate directly with each RU in one or more RUs 340 via the corresponding O1 interface. The SMO framework 305 can also include a non-RT RIC 315 configured to support the functionality of the SMO framework 305.

[0082] The non-RT RIC 315 can be configured to include logic functions that enable non-real-time control and optimization of RAN elements and resources, artificial intelligence / machine learning (AI / ML) workflows including model training and updating, or policy-based guidance of 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 the A1 interface). The near-RT RIC 325 can be configured to include logic functions that enable near-real-time control and optimization of RAN elements and resources via data collection and actions through an interface (such as via the E2 interface), which connects one or more CUs 310, one or more DUs 330, or both, and the O-eNB to the near-RT RIC 325.

[0083] In some specific implementations, to generate an AI / ML model to be deployed in the near-RT RIC 325, the non-RT RIC 315 can receive parameters or external enrichment information from an external server. Such information can be utilized by the near-RT RIC 325 and can be received from non-network data sources or from network functions at the SMO framework 305 or at the non-RT RIC 315. In some examples, the non-RT RIC 315 or the near-RT RIC 325 can be configured to tune RAN behavior or performance. For example, the non-RT RIC 315 can monitor long-term trends and patterns of performance and employ an AI / ML model to perform corrective actions through the SMO framework 305 (such as reconfiguration via the O1 interface) or via the creation of RAN management policies (such as A1 interface policies).

[0084] As indicated above, Figure 3 is provided as an example. Other examples may be different from the examples Figure 3 described.

[0085] Figure 4 FIGS. 400, 405, and 410 are diagrams illustrating examples of full-duplex communication in a wireless network according to the present disclosure. "Full-duplex communication" in a wireless network refers to simultaneous two-way communication between devices in the wireless network. For example, a UE operating in full-duplex mode can simultaneously transmit uplink communication and receive downlink communication (e.g., in the same time slot or the same symbol). "Half-duplex communication" in a wireless network refers to one-way communication (e.g., only downlink communication or only uplink communication) between devices at a given time (e.g., in a given time slot or a given symbol).

[0086] As Figure 4As shown, Examples 400 and 405 illustrate examples of in-band full-duplex (IBFD) communication. In IBFD, a UE can transmit uplink communication to and receive downlink communication from a base station on the same time and frequency resources. As shown in Example 400, in a first example of IBFD, the time and frequency resources for uplink communication can completely overlap with the time and frequency resources for downlink communication. As shown in Example 405, in a second example of IBFD, the time and frequency resources for uplink communication can partially overlap with the time and frequency resources for downlink communication.

[0087] As Figure 4 Further shown, Example 410 illustrates an example of sub-band full-duplex (SBFD) communication, which can also be referred to as "sub-band frequency-division duplex (SBFDD)" or "flexible duplex". In SBFD, a UE can transmit uplink communication to and receive downlink communication from a base station at the same time but on different frequency resources. For example, the different frequency resources can be sub-bands of a frequency band such as a time-division duplex frequency band. In this case, the frequency resources for downlink communication can be separated from the frequency resources for uplink communication in the frequency domain by a guard band.

[0088] In some specific implementations, the techniques and apparatuses associated with UE-to-UE CLI reporting described herein can be implemented for full-duplex communication (e.g., SBFD communication), as described with respect to Figure 4 as described.

[0089] As indicated above, Figure 4 is provided as an example. Other examples can be different from those described with respect to Figure 4 described.

[0090] Figure 5 is a diagram illustrating Example 500 of SBFD activation according to the present disclosure. As Figure 5 shown, Example 500 includes a first configuration 502. In some aspects, the first configuration 502 can indicate a first time slot format mode (sometimes referred to as a TDD mode) associated with a half-duplex mode or a full-duplex mode. The first time slot format mode can include a certain number of downlink time slots (e.g., three downlink time slots 504a, 504b, and 504c as shown), a certain number of flexible time slots (not shown), and / or a certain number of uplink time slots (e.g., one uplink time slot 506 as shown). The first time slot format mode can repeat over time. In some aspects, network node 110 can use one or more time slot format indicators to indicate the first time slot format mode to UE 120. The time slot format indicator for a time slot can indicate whether the time slot is an uplink time slot, a downlink time slot, or a flexible time slot, etc.

[0091] The network node 110 may direct (e.g., using an indication such as a Radio Resource Control (RRC) message, a Medium Access Control (MAC) Control Element (CE) (MAC-CE), or Downlink Control Information (DCI)) the UE 120 to switch from the first configuration 502 to the second configuration 508. As an alternative, the UE 120 may indicate to the network node 110 that the UE 120 is switching from the first configuration 502 to the second configuration 508. The second configuration 508 may indicate a second time slot format pattern that repeats over time, similar to the first time slot format pattern. In any of the aspects described above, the UE 120 may switch from the first configuration 502 to the second configuration 508 during a period of time (e.g., a certain number of symbols and / or a certain amount of time (e.g., in ms)) at least partially based on an indication received from the network node 110 (e.g., before switching back to the first configuration 502). During this period of time, the UE 120 may communicate using the second time slot format pattern and may then resume using the first time slot format pattern after the end of this period of time. The period of time may be indicated by the network node 110 (e.g., in the instruction to switch from the first configuration 502 to the second configuration 508, as described above) and / or at least partially based on programmed and / or otherwise pre-configured rules. For example, the rule may be at least partially based on a table (e.g., defined in 3GPP specifications and / or another wireless communication standard) that associates different Subcarrier Spacings (SCSs) and / or parameter sets (e.g., represented by μ and associated with the corresponding SCS) with corresponding periods of time for the handover configuration.

[0092] In example 500, the second time slot format pattern includes two SBFD time slots instead of the downlink time slot in the first time slot format pattern. In example 500, each SBFD time slot includes a partial time slot for downlink (e.g., a portion or sub-band of the frequency allocated for use by the network node 110 and the UE 120) (e.g., partial time slots 512a, 512b, 512c, and 512d as shown) and a partial time slot for uplink (e.g., partial time slots 514a and 514b as shown). Thus, compared to operating using the first time slot format pattern (e.g., the fourth time slot in the sequence, shown as UL time slot 506), the UE 120 may operate using the second time slot format pattern to transmit uplink communication in an earlier time slot (e.g., the second time slot in the sequence, shown as partial UL time slot 514a). Other examples may include additional or alternative variations. For example, the second configuration 508 may indicate SBFD time slots instead of the uplink time slot (e.g., UL time slot 506) in the first configuration 502. In another example, the second configuration 508 may indicate a downlink time slot or an uplink time slot instead of the SBFD time slot in the first configuration 502 ( Figure 5(not shown in the figure). In yet another example, the second configuration 508 may indicate a downlink time slot or an uplink time slot to replace the uplink time slot or the downlink time slot in the first configuration 502, respectively. An "SBFD time slot" may refer to a time slot in which the SBFD format is used. The SBFD format may include a time slot format that supports full-duplex communication (e.g., for both uplink and downlink communications), where one or more frequencies for the uplink portion of the time slot are separated from one or more frequencies for the downlink portion of the time slot by a guard band. In some aspects, the SBFD format may include a single uplink portion and a single downlink portion separated by a guard band. In some aspects, the SBFD format may include multiple downlink portions and a single uplink portion, where the single uplink portion is separated from the multiple downlink portions by corresponding guard bands (e.g., as shown in Figure 5 ). In some aspects, the SBFD format may include multiple uplink portions and a single downlink portion, where the single downlink portion is separated from the multiple uplink portions by corresponding guard bands. In some aspects, the SBFD format may include multiple uplink portions and multiple downlink portions, where each uplink portion is separated from a downlink portion by a guard band. In some aspects, operating in the SBFD mode may include activating or using the FD mode in one or more time slots at least partially based on one or more time slots having the SBFD format. A time slot may support the SBFD mode if the UL BWP and the DL BWP are allowed to be active or simultaneously active in the time slot in the SBFD manner (e.g., by guard band separation).

[0093] By switching from the first configuration 502 to the second configuration 508, the network node 110 and the UE 120 may experience increased communication quality and / or reliability. For example, the network node 110 and the UE 120 may experience increased throughput (e.g., using the full-duplex mode), reduced latency (e.g., the UE 120 may be able to send uplink and / or downlink communications faster using the second configuration 508 instead of the first configuration 502), and increased network resource utilization (e.g., by using both the DL BWP and the UL BWP simultaneously instead of only using the DL BWP or the UL BWP).

[0094] In some specific implementations, the techniques and apparatuses described herein associated with UE-to-UE CLI reporting may be implemented in SBFD time slots, as described with respect to Figure 5 .

[0095] As indicated above, Figure 5 is provided as an example. Other examples may be different from those described with respect to Figure 5 .

[0096] Figure 6 FIG. is an illustration of example 600 related to cross-link interference (CLI) in accordance with the present disclosure.

[0097] As Figure 6 shown, when an adjacent network node 110 communicates with a UE 120 using an SBFD configuration or a different time-division duplex (TDD) configuration (e.g., when implementing dynamic TDD or flexible TDD), this can result in downlink communication 610 between a first network node 110-1 and a first UE 120-1 in the same transmission time interval (TTI) as uplink communication 620 between a second network node 110-2 and a second UE 120-2. These communications in different transmission directions (e.g., downlink versus uplink) in the same TTI may interfere with each other, which can be referred to as cross-link interference.

[0098] For example, as indicated by reference numeral 630, downlink communication 610 transmitted by the first network node 110-1 may be received by the second network node 110-2 and may interfere with the second network node 110-2 receiving uplink communication 620 from the second UE 120-2. This can be referred to as downlink-to-uplink (DL-to-UL) interference, network node-to-network node interference, or gNB-to-gNB interference.

[0099] In addition, as indicated by reference numeral 640, uplink communication 620 transmitted by the second UE 120-2 may be received by the first UE 120-1 and may interfere with the first UE 120-1 receiving downlink communication 610 from the first network node 110-1. This can be referred to as uplink-to-downlink (UL-to-DL) interference or UE-to-UE interference. This UE-to-UE interference may occur and / or may increase when the first UE 120-1 and the second UE 120-2 are in close proximity.

[0100] In some specific implementations, the techniques and apparatuses associated with UE-to-UE CLI reporting described herein may be implemented in connection with measuring and reporting UE-to-UE CLI, as described with respect to Figure 6 that which is described.

[0101] As indicated above, Figure 6 is provided as an example. Other examples are possible and may be different from that which is described with respect to Figure 6 that which is described.

[0102] A wireless communication system may support SBFD communication or dynamic TDD communication. However, as described above, UE-to-UE CLI (also referred to as inter-UE CLI) may occur during such communication.

[0103] For example, in the SBFD scenario, the first UE in a cell transmitting uplink communication on an uplink sub-band (SB) in an SBFD symbol may interfere with the second UE in the cell receiving downlink communication on a downlink SB in the SBFD symbol. This interference may be referred to as inter-SB intra-cell UE-to-UE CLI. As another example, in the SBFD scenario, the first UE in a first cell transmitting uplink communication on an uplink SB in an SBFD symbol may interfere with the second UE in a second cell receiving downlink communication on a downlink SB in the SBFD symbol. This interference may be referred to as inter-SB inter-cell UE-to-UE CLI.

[0104] As another example, in the dynamic TDD scenario, the first UE in a first cell transmitting uplink communication in a symbol may interfere with the second UE in a second cell receiving downlink communication in the symbol. This interference may be referred to as inter-cell UE-to-UE CLI.

[0105] If information associated with UE-to-UE CLI is available to the network, the network may improve the performance and reliability of SBFD communication or dynamic TDD communication.

[0106] Some of the techniques and apparatuses described herein implement UE-to-UE CLI reporting. In some specific implementations, a network node may send and a UE may receive a configuration associated with measuring or reporting characteristics of a UE-to-UE CLI reference signal in an uplink SB of a network node SBFD symbol. The UE may measure characteristics of the UE-to-UE CLI reference signal in the SB of the network node SBFD symbol (e.g., according to the configuration). Then, the UE may send and the network node may receive a report that includes information associated with the characteristics of the UE-to-UE CLI reference signal in the uplink SB (e.g., according to the configuration). In some specific implementations, a network node may send and a UE may receive a configuration associated with measuring or reporting characteristics of a UE-to-UE CLI reference signal in multiple sub-SBs of a symbol, the multiple sub-SBs being included in the SB of the symbol. The UE may measure characteristics of the UE-to-UE CLI reference signal in the multiple sub-SBs of the symbol (e.g., according to the configuration). Then, the UE may send and the network node may receive a report that includes information associated with the characteristics of the UE-to-UE CLI reference signal in the multiple sub-SBs.

[0107] In this way, the UE may determine and report information associated with UE-to-UE CLI, thereby providing the information associated with UE-to-UE to the network so that the network can adjust or control SBFD communication or dynamic TDD communication to improve performance or reliability. Additional details are provided below.

[0108] Figure 7is a diagram illustrating an example 700 associated with UE-to-UE CLI reporting according to the present disclosure. As Figure 7 shown, example 700 includes communications between network node 110, UE 120-1, and UE 120-2. In some aspects, network node 110, UE 120-1, and UE 120-2 may be included in a wireless network (such as wireless network 100). In some specific implementations, network node 110 and UE 120-1 may communicate via a wireless access link (which may include an uplink and a downlink).

[0109] As shown by reference numeral 702, network node 110 may send and UE 120-1 may receive a configuration associated with measuring or reporting characteristics of a UE-to-UE CLI reference signal in an uplink SB of a network node SBFD symbol. A network node SBFD symbol is a symbol configured such that network node 110 can simultaneously send and receive communications with multiple UEs 120 in different SBs. For example, a network node SBFD symbol may be a symbol configured to include an uplink SB and a downlink SB separated by a guard band. Here, network node 110 may simultaneously receive uplink communications from a first UE 120 in the uplink SB and send downlink communications to a second UE 120 in the downlink SB. In this example, the first UE 120 and / or the second UE 120 may be a half-duplex UE, and thus support SBFD operation on the network side (rather than the UE side).

[0110] In some specific implementations, the configuration includes information at least partially based on information that UE 120-1 is to measure characteristics of the UE-to-UE CLI reference signal or report information associated with the measured characteristics of the UE-to-UE CLI reference signal. For example, the configuration may indicate characteristics to be measured by UE 120-1. For example, the characteristics may be reference signal received power (RSRP) or received signal strength indicator (RSSI), etc. As another example, the configuration may indicate the uplink SB in which the characteristics are to be measured. As another example, the configuration may indicate the SBFD symbol in which the characteristics are to be measured. As another example, the configuration may indicate a resource set (e.g., one or more uplink SBs, one or more SBFD symbols) in which UE 120-1 may expect to receive the UE-to-UE CLI reference signal to receive the UE-to-UE CLI reference signal.

[0111] As shown by reference numeral 704, UE 120-2 may transmit a UE-to-UE CLI reference signal. In some specific implementations, the UE-to-UE CLI reference signal may be, for example, a sounding reference signal (SRS) transmitted by UE 120-2 on the uplink or another type of signal. In some specific implementations, UE 120-2 may transmit the UE-to-UE CLI reference signal at least partially based on a configuration from network node 110. For example, network node 110 may transmit and UE 120-2 may receive a configuration indicating a resource set (e.g., one or more SBs, one or more symbols) in which UE 120-2 is to transmit the UE-to-UE CLI reference signal, and UE 120-2 may transmit the UE-to-UE CLI reference signal in the indicated resource set.

[0112] As shown by reference numeral 706, UE 120-1 may measure characteristics of the UE-to-UE CLI reference signal in the uplink SB of the network node SBFD symbol. In some specific implementations, UE 120-1 measures the characteristics of the UE-to-UE CLI reference signal in the uplink SB in association with detecting a CLI within the SB that affects the dynamic range of the receiver or causes the automatic gain control (AGC) of the receiver to block. That is, in some specific implementations, UE 120-1 measures the characteristics of the UE-to-UE CLI reference signal in association with detecting whether there is a blocker in the uplink SB.

[0113] In some specific implementations, UE 120-1 measures the characteristics of the UE-to-UE CLI reference signal with a subcarrier spacing (SCS) configured for the uplink SB including the UE-to-UE CLI reference signal resource on the network node SBFD symbol. In some specific implementations, in association with measuring the characteristics of the UE-to-UE CLI reference signal, it is not expected that UE measures the characteristics with an SCS other than the SCS configured for the uplink SB including the UE-to-UE CLI reference signal resource on the network node SBFD symbol. For example, the UE-to-UE CLI reference signal may be an SRS, and the characteristic may be RSRP (e.g., SRS-RSRP). Here, in association with measuring SRS-RSRP, in some specific implementations, it is not expected that UE 120-1 measures SRS-RSRP with an SCS other than the SCS configured for the uplink SB limiting the SRS resource on the SBFD symbol.

[0114] In some specific implementations, UE 120-1 uses measurement resources within the uplink SB that are restricted to the network node SBFD symbols to measure the characteristics of the UE-to-UE CLI reference signal. In some specific implementations, associated with measuring the characteristics of the UE-to-UE CLI reference signal, it is not desired that the UE use measurement resources within the uplink SB that are not restricted to the network node SBFD symbols to measure the characteristics of the UE-to-UE CLI reference signal. For example, the UE-to-UE CLI reference signal can be an SRS, and the characteristic can be an RSRP (e.g., SRS-RSRP). Here, associated with measuring the SRS-RSRP, in some specific implementations, it is not desired that UE 120-1 use SRS-RSRP measurement resources within the uplink subband that are not fully restricted to the SBFD symbols to measure the SRS-RSRP.

[0115] In some specific implementations, when measuring the characteristics of the UE-to-UE CLI reference signal in the uplink SB of the network node SBFD, UE 120 can measure the characteristics of the UE-to-UE CLI reference signal in multiple sub-SBs of the uplink SB. The multiple sub-SBs can include, for example, the first edge sub-SB of the first SB, the central sub-SB of the first SB, and the second edge sub-SB of the first SB. In some specific implementations, the sub-SB measurement and reporting of the characteristics within the uplink SB report enables the identification of a subset of resource blocks (RBs) within the uplink SB that experience different CLIs. This information can allow the network node 110, for example, to reconfigure one or more SBs to provide or enhance CLI mitigation.

[0116] As shown by reference numeral 708, UE 120-1 can send and the network node 110 can receive a report that includes information associated with the characteristics of the UE-to-UE CLI reference signal in the uplink SB.

[0117] In some specific implementations, the information associated with the characteristics of the UE-to-UE CLI reference signal in the uplink SB includes an indication of whether there is an obstruction in the uplink SB. For example, in some specific implementations, UE 120-1 may determine whether the measured characteristics of the UE-to-UE CLI reference signal in the uplink SB meet a threshold. Here, if the characteristics meet the threshold (e.g., if the RSRP is greater than or equal to the threshold), then UE 120-1 may determine that there is an obstruction in the uplink SB (e.g., the CLI within the SB may affect the dynamic range of the receiver or cause AGC blocking of the receiver). In this example, the information associated with the characteristics includes an indication that the characteristics meet the threshold (e.g., there is an obstruction in the uplink SB). Conversely, if the characteristics do not meet the threshold (e.g., if the RSRP is less than the threshold), then UE 120-1 may determine that there is no obstruction in the uplink SB. In this example, the information associated with the characteristics includes an indication that the characteristics do not meet the threshold (e.g., there is no obstruction in the uplink SB).

[0118] In some specific implementations, the information associated with the characteristics of the UE-to-UE CLI reference signal in the uplink SB may include a one-bit indication associated with the characteristics. For example, the information associated with the characteristics may be a one-bit indication of whether there is an obstruction in the uplink SB (e.g., value 1 indicates an obstruction, value 0 indicates no obstruction).

[0119] In some specific implementations, the information associated with the characteristics may include another type of information associated with the characteristics, such as the value of the characteristics (e.g., the information may indicate the RSRP measured in the uplink SB). In some specific implementations, the information associated with the characteristics of the UE-to-UE CLI reference signal includes the information associated with the characteristics of the CLI reference signal measured in multiple sub-SBs (e.g., when UE 120-1 is configured to measure the characteristics in multiple sub-SBs, as described above).

[0120] As indicated above, Figure 7 is provided as an example. Other examples may be different from those Figure 7 described.

[0121] Figure 8 is a diagram illustrating Example 800 associated with UE-to-UE CLI reporting according to the present disclosure. As Figure 8As shown, Example 800 includes communication between network node 110, UE 120-1, and UE 120-2. In some aspects, network node 110, UE 120-1, and UE 120-2 may be included in a wireless network (such as wireless network 100). In some embodiments, network node 110 and UE 120-1 may communicate via a wireless access link (which may include an uplink and a downlink).

[0122] As shown by reference numeral 802, network node 110 may send and UE 120-1 may receive a configuration associated with characteristics of a UE-to-UE CLI reference signal in a plurality of sub-SBs of a measurement or reporting symbol, the plurality of sub-SBs being included in an SB of the symbol.

[0123] In some embodiments, the configuration includes information that is at least partially based on UE 120-1 measuring characteristics of the UE-to-UE CLI reference signal or reporting information associated with the measured characteristics of the UE-to-UE CLI reference signal. For example, the configuration may indicate the characteristics to be measured by UE 120-1. The characteristics may be, for example, RSRP, RSSI, or signal-to-interference-plus-noise ratio (SINR), etc. As another example, the configuration may indicate the SB in which the characteristics are to be measured. As another example, the configuration may indicate the symbol in which the characteristics are to be measured. As another example, the configuration may indicate a resource set (e.g., one or more uplink SBs, one or more downlink SBs, one or more symbols) in which UE 120-1 may expect to receive the UE-to-UE CLI reference signal to receive the UE-to-UE CLI reference signal.

[0124] As shown by reference numeral 804, UE 120-2 may send a UE-to-UE CLI reference signal. In some embodiments, the UE-to-UE CLI reference signal may be, for example, an SRS or another type of signal sent by UE 120-2 on the uplink. In some embodiments, UE 120-2 may send the UE-to-UE CLI reference signal at least partially based on a configuration from network node 110. For example, network node 110 may send and UE 120-2 may receive a configuration indicating a resource set (e.g., one or more SBs, one or more symbols) in which UE 120-2 is to send the UE-to-UE CLI reference signal, and UE 120-2 may send the UE-to-UE CLI reference signal in the indicated resource set.

[0125] As shown by reference numeral 806, UE 120-1 may measure characteristics of the UE-to-UE CLI reference signal in multiple sub-SBs of a symbol. In some specific implementations, the multiple sub-SBs may include a first edge sub-SB of a first SB, a central sub-SB of the first SB, and a second edge sub-SB of the first SB. In some specific implementations, the sub-SB measurement and reporting of characteristics within an SB report enables identification of a subset of RBs within the SB that experience different CLIs. This information may allow network node 110 to, for example, reconfigure one or more uplink SBs or one or more downlink SBs to provide or enhance CLI mitigation.

[0126] In some specific implementations, the SB in which UE 120-1 measures the characteristics of the UE-to-UE CLI reference signal in multiple sub-SBs may be an uplink SB. In some specific implementations, the characteristics of the UE-to-UE CLI reference signal are measured in the uplink SB in association with detecting a CLI within the SB that affects the dynamic range of the receiver or causes the automatic gain control (AGC) of the receiver to block. That is, in some specific implementations, UE 120-1 measures the characteristics of the UE-to-UE CLI reference signal in association with detecting whether there is a blocker in the uplink SB.

[0127] In some specific implementations, the SB in which UE 120-1 measures the characteristics of the UE-to-UE CLI reference signal in multiple sub-SBs may be a downlink SB. In some specific implementations, the characteristics of the UE-to-UE CLI reference signal are measured in the downlink SB in association with detecting inter-SB leakage (e.g., interference from different SBs).

[0128] In some specific implementations, the symbol in which UE 120-1 measures the characteristics of the UE-to-UE CLI reference signal is a network node SBFD symbol. Alternatively, the symbol in which UE 120-1 measures the characteristics of the UE-to-UE CLI reference signal may be configured as an SBFD symbol and may be an old-fashioned downlink symbol or an old-fashioned flexible symbol. For example, in a TDD common slot format, a slot or symbol may be configured as downlink, uplink, or flexible. However, for SBFD operation, an old-fashioned downlink symbol or slot may be indicated or configured as an SBFD symbol or slot for SBFD operation (e.g., for some UEs 120 to transmit uplink communication in an uplink SB of an SBFD symbol for SBFD operation, and for other UEs 120 to receive downlink communication in a downlink SB of the SBFD symbol). Thus, in some specific implementations, the symbol may be an old-fashioned downlink symbol or an old-fashioned flexible symbol configured as an SBFD symbol.

[0129] In some specific implementations, UE 120-1 can measure the characteristics of the UE-to-UE CLI reference signal in multiple symbols associated with multiple SBs. For example, UE 120-1 can measure the characteristics of the UE-to-UE CLI reference signal in the first multiple sub-SBs of a symbol (e.g., the multiple sub-SBs included in the first SB), can measure the characteristics of the UE-to-UE CLI reference signal in the second multiple sub-SBs of a symbol (e.g., the multiple sub-SBs included in the second SB), and so on. As a specific example, UE 120-1 can measure the RSRP of the SRS in the multiple sub-SBs of the downlink SB of the SBFD symbol, and can measure the RSRP of the SRS in the multiple sub-SBs of the uplink SB of the SBFD symbol (e.g., when the SBFD symbol has a D / U configuration). As another specific example, UE 120-1 can measure the RSRP of the SRS in the multiple sub-SBs of the first downlink SB of the SBFD symbol, can measure the RSRP of the SRS in the multiple sub-SBs of the uplink SB of the SBFD symbol, and can measure the RSRP of the SRS in the multiple sub-SBs of the second downlink SB of the SBFD symbol (e.g., when the SBFD symbol has a D / U / D configuration).

[0130] As shown by reference numeral 808, UE 120-1 can send and network node 110 can receive a report that includes information associated with the characteristics of the UE-to-UE CLI reference signal in multiple sub-SBs.

[0131] In some specific implementations, if the SB is an uplink SB, the information associated with the characteristics of the UE-to-UE CLI reference signal in multiple sub-SBs includes an indication of whether there is an obstruction in a given sub-SB of the uplink SB. For example, in some specific implementations, UE 120-1 can determine whether the measured characteristics of the UE-to-UE CLI reference signal in a given sub-SB of the uplink SB meet a threshold. Here, if the characteristics meet the threshold, UE 120-1 can determine that there is an obstruction in the sub-SB of the uplink SB (e.g., the CLI within the SB may affect the dynamic range of the receiver or cause AGC blocking of the receiver). In this example, the information associated with the characteristics includes an indication that the characteristics meet the threshold. On the contrary, if the characteristics fail to meet the threshold, UE 120-1 can determine that there is no obstruction in the sub-SB of the uplink SB. In this example, the information associated with the characteristics includes an indication that the characteristics fail to meet the threshold.

[0132] In some specific implementations, if the SB is a downlink SB, the information associated with the characteristics of the UE-to-UE CLI reference signal in a plurality of sub-SBs includes an indication of whether there is a threshold amount of inter-SB CLI leakage in a given sub-SB of the downlink SB. For example, in some specific implementations, UE 120-1 may determine whether the measured characteristics of the UE-to-UE CLI reference signal in a given sub-SB of the downlink SB meet a threshold. Here, if the characteristics meet the threshold, UE 120-1 may determine that there is a threshold amount of inter-SB CLI leakage in the sub-SB of the downlink SB. In this example, the information associated with the characteristics includes an indication that the characteristics meet the threshold. Conversely, if the characteristics fail to meet the threshold, UE 120-1 may determine that there is a non-substantial amount of inter-SB leakage in the sub-SB of the downlink SB. In this example, the information associated with the characteristics includes an indication that the characteristics fail to meet the threshold.

[0133] In some specific implementations, the information associated with the characteristics of the UE-to-UE CLI reference signal in a given sub-SB may include a one-bit indication associated with the characteristics. For example, the information associated with the characteristics may be a one-bit indication of whether there is an obstruction in a given sub-SB of the uplink SB (e.g., value 1 indicates an obstruction, value 0 indicates no obstruction). As another example, the information associated with the characteristics may be a one-bit indication of whether there is inter-SB leakage in a given sub-SB of the downlink SB (e.g., value 1 indicates inter-SB CLI leakage, value 0 indicates no inter-SB CLI leakage or no substantial inter-SB CLI leakage).

[0134] In some specific implementations, the information associated with the characteristics of a given sub-SB may include another type of information associated with the characteristics, such as the value of the characteristics (e.g., the information may indicate the RSRP as measured in the sub-SB). In some embodiments, the information associated with the characteristics of the UE-to-UE CLI reference signal includes the information associated with the characteristics of the CLI reference signal measured in each of the plurality of sub-SBs (e.g., for one SB or for more than one SB).

[0135] As indicated above, Figure 8 is provided as an example. Other examples may be different from those Figure 8 described.

[0136] Figure 9 is a diagram illustrating an example process 900 performed, for example, by a UE in accordance with the present disclosure. Example process 900 is an example in which a UE (e.g., UE 120) performs operations associated with UE-to-UE CLI reporting.

[0137] As Figure 9As shown, in some aspects, process 900 may include measuring the characteristics of the UE-to-UE CLI reference signal in the uplink SB of the network node SBFD symbols (block 910). For example, a UE (e.g., using Figure 13 the communication manager 140 and / or the measurement component 1308 depicted in

[0138] As Figure 9 further shown, in some aspects, process 900 may include transmitting a report including information associated with the characteristics of the UE-to-UE CLI reference signal in the uplink SB (block 920). For example, a UE (e.g., using Figure 13 the communication manager 140 and / or the transmission component 1304 depicted in

[0139] Process 900 may include additional aspects, such as any single aspect or any combination of aspects described below and / or in combination with one or more other processes described elsewhere herein.

[0140] In a first aspect, the characteristic includes RSRP, RSSI, or some combination thereof.

[0141] In a second aspect, either alone or in combination with the first aspect, the information associated with the characteristic of the UE-to-UE CLI reference signal in the uplink SB includes an indication of whether an obstruction is present in the uplink SB.

[0142] In a third aspect, either alone or in combination with one or more of the first and second aspects, the characteristic of the UE-to-UE CLI reference signal in the uplink SB is measured in association with detecting an SB-in-CLI that affects the dynamic range of the receiver or causes AGC blocking in the receiver.

[0143] In a fourth aspect, either alone or in combination with one or more of the first to third aspects, the information associated with the characteristic of the UE-to-UE CLI reference signal in the uplink SB includes a one-bit indication associated with the characteristic.

[0144] In a fifth aspect, either alone or in combination with one or more of the first to fourth aspects, process 900 includes determining whether the characteristic of the UE-to-UE CLI reference signal in the uplink SB meets a threshold, where the information associated with the characteristic includes an indication of whether the characteristic meets the threshold.

[0145] In a sixth aspect, either alone or in combination with one or more of the first to fifth aspects, in association with measuring the characteristic of the UE to the UE CLI reference signal, it is not expected that the UE measures the characteristic through a SCS other than the SCS configured for the uplink SB including the UE to UE CLI reference signal resource on the network node SBFD symbol.

[0146] In a seventh aspect, either alone or in combination with one or more of the first to sixth aspects, measure the characteristic of the UE to the UE CLI reference signal through the SCS configured for the uplink SB including the UE to UE CLI reference signal resource on the network node SBFD symbol.
