Description

[0001] Cross-reference to related applications

[0002] This patent application claims priority to U.S. Provisional Patent Application No. 63 / 138,209, filed January 15, 2021, entitled “Enhanced Duplexing Capability Indication in Integrated Access and Backhaul Networks,” and U.S. Non-Provisional Patent Application No. 17 / 647,806, filed January 12, 2022, entitled “Enhanced Duplexing Capability Indication in Wireless Networks,” which are expressly incorporated herein by reference. Technical Field

[0003] This disclosure relates generally to wireless communication, and specifically to techniques and apparatus for indicating enhanced duplex capability in wireless networks. Background Technology

[0004] Wireless communication systems are widely deployed to provide a variety of telecommunications services, such as telephone, video, data, messaging, and broadcasting. Typical wireless communication systems may employ multiple access technologies capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth and / or transmit power). 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).

[0005] A wireless network may include multiple base stations (BSs) capable of supporting communication for multiple user equipments (UEs). UEs may communicate with the BS via downlinks and uplinks. A "downlink" (or "forward link") refers to the communication link from the BS to the UE, and an "uplink" (or "backlink") refers to the communication link from the UE to the BS. As will be described in more detail herein, a BS may be referred to as a Node B, gNB, Access Point (AP), Radio Headend, Transmit / Receive Point (TRP), New Radio (NR) BS, and / or 5G Node B, etc.

[0006] The aforementioned multiple access technologies have been adopted in various telecommunications standards to provide a common protocol enabling different user equipment to communicate at the city, country, region, and even global levels. 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 better integrating with other open standards that use Orthogonal Frequency Division Multiplexing (OFDM) with a Cyclic Prefix (CP) on the downlink (DL) and CP-OFDM and / or SC-FDM (e.g., also known as Discrete Fourier Transform Spread Spectrum OFDM (DFT-s-OFDM)) on the uplink (UL), as well as supporting beamforming, multiple-input multiple-output (MIMO) antenna technologies, and carrier aggregation. Further improvements to LTE, NR, and other wireless access technologies remain useful as the demand for mobile broadband access continues to grow. Summary of the Invention

[0028] Various aspects of this disclosure are described more fully below with reference to the accompanying drawings. However, this disclosure may be embodied in many different forms and should not be construed as being limited to any particular structure or function presented throughout this disclosure. Rather, these aspects are provided to make this disclosure thorough and complete, and to fully convey the scope of this disclosure to those skilled in the art. Based on the teachings herein, those skilled in the art should understand that the scope of this disclosure is intended to cover any aspect disclosed herein, whether implemented independently of 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 practice. Furthermore, the scope of this disclosure is intended to cover an apparatus or method practiced using a structure, function, or structure and function other than or different from the aspects of this disclosure set forth herein. It should be understood that any aspect of this disclosure may be embodied by one or more elements of the claims.

[0029] Several aspects of a telecommunications system will now be presented with reference to various devices and techniques. These devices and techniques will be described in detail below and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes and / or algorithms, and other examples (collectively, “elements”). These elements can be implemented using hardware, software, or a combination thereof. Whether these elements are implemented in hardware or software depends on the specific application and the design constraints on the overall system.

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

[0031] Figure 1 This is a diagram illustrating an example of a wireless network 100 according to this disclosure. The wireless network 100 may be or may include elements of a 5G (NR) network and / or an LTE network, etc. The wireless network 100 may include multiple base stations 110 (shown as BS110a, BS 110b, BS 110c, and BS 110d) and other network entities. A base station (BS) is an entity that communicates with a user equipment (UE) and may also be referred to as an NR BS, Node B, gNB, 5G Node B (NB), access point, Transmit / Receive Point (TRP), etc. Each BS may provide communication coverage for a specific geographic area. In 3GPP, the term "cell" may refer to the coverage area of ​​a BS and / or the BS subsystem serving that coverage area, depending on the context in which the term is used.

[0032] A Base Station (BS) can provide communication coverage for macrocells, picocells, femtocells, and / or another type of cell. A macrocell can cover a relatively large geographic area (e.g., a radius of several kilometers) and allow unrestricted access for UEs with service subscriptions. A picocell can cover a relatively small geographic area and allow unrestricted access for UEs with service subscriptions. A femtocell can cover a relatively small geographic area (e.g., a home) and allow restricted access for UEs associated with that femtocell (e.g., UEs in a Closed Subscriber Group (CSG)). A BS for a macrocell can be referred to as a macro BS. A BS for a picocell can be referred to as a pico BS. A BS for a femtocell can be referred to as a femtocell BS or a home BS. Figure 1 In the example shown, BS 110a can be a macro BS of macro cell 102a, BS 110b can be a pico BS of pico cell 102b, and BS 110c can be a femto BS of femto cell 102c. A BS can support one or more (e.g., three) cells. The terms “eNB,” “base station,” “NR BS,” “gNB,” “TRP,” “AP,” “Node B,” “5G NB,” and “cell” are used interchangeably herein.

[0033] In some respects, the cell is not necessarily stationary, and the geographical area of ​​the cell can move depending on the location of the mobile BS. In some respects, BSs can use any suitable transport network to interconnect with each other and / or interconnect to one or more other BSs or network nodes (not shown) in the wireless network 100 via various types of backhaul interfaces, such as direct physical connections or virtual networks.

[0034] The wireless network 100 may also include relay stations. A relay station is an entity that can receive data transmissions from an upstream station (e.g., a BS or a UE) and send data transmissions to a downstream station (e.g., a UE or a BS). A relay station can also be a UE capable of relaying transmissions for other UEs. Figure 1 In the example shown, relay BS 110d can communicate with macro BS 110a and UE 120d to facilitate communication between BS 110a and UE 120d. A relay BS can also be referred to as a relay station, relay base station, relay, etc.

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

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

[0037] UEs 120 (e.g., 120a, 120b, 120c) may be distributed throughout the wireless network 100, and each UE may be fixed or mobile. A UE may also be referred to as an access terminal, terminal, mobile station, subscriber unit, station, etc. A UE 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 or equipment, a biosensor / device, a wearable device (smartwatch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet)), an entertainment device (e.g., a music or video device, or a satellite radio), a vehicle component or sensor, a smart meter / sensor, industrial manufacturing equipment, a GPS device, or any other suitable device configured to communicate via wireless or wired media.

[0038] Some UEs can be considered Machine-Type Communication (MTC) or Evolved or Enhanced Machine-Type Communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, and / or location tags that can communicate with base stations, another device (e.g., a remote device), or some other entity. For example, a wireless node can provide connectivity to or from a network (e.g., a wide area network such as the Internet or cellular networks) via wired or wireless communication links. Some UEs can be considered Internet of Things (IoT) devices and / or can be implemented as NB-IoT (Narrowband Internet of Things) devices. Some UEs can be considered Customer Premises Equipment (CPE). UE 120 can be included within a housing housing the components of UE 120, such as processor components and / or memory components. In some respects, the processor components and memory components can be coupled together. For example, the processor components (e.g., one or more processors) and memory components (e.g., memory) can be operatively coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0039] Typically, any number of wireless networks can be deployed in a given geographical area. Each wireless network can support a specific Radio Access Platform (RAT) and can operate on one or more frequencies. A RAT can also be referred to as a radio technology, air interface, etc. A frequency can also be referred to as a carrier, channel, etc. 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.

[0040] In some respects, 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 base station 110 as a medium for communication with each other). For example, UEs 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 or vehicle-to-infrastructure (V2I) protocols) and / or mesh networks. In this case, UEs 120 may perform scheduling operations, resource selection operations, and / or other operations performed by base station 110 as described elsewhere herein.

[0041] Devices of wireless network 100 may communicate using the electromagnetic spectrum, which may be subdivided into various classes, bands, channels, etc., based on frequency or wavelength. For example, devices of wireless network 100 may communicate using an operating band having a first frequency range (FR1) spanning from 410 MHz to 7.125 GHz, and / or may communicate using an operating band having a second frequency range (FR2) spanning from 24.25 GHz to 52.6 GHz. Frequency between FR1 and FR2 is sometimes referred to as intermediate frequency (IF) band. Although a portion of FR1 is greater than 6 GHz, FR1 is generally referred to as the “below 6 GHz” band. Similarly, FR2 is often referred to as the “millimeter wave” band, although it differs from the extremely high frequency (EHF) band (30 GHz–300 GHz) identified as the “millimeter wave” band by the International Telecommunication Union (ITU). Therefore, unless specifically stated otherwise, it should be understood that the use of the terms “below 6 GHz”, etc., herein can broadly refer to frequencies less than 6 GHz, frequencies within FR1, and / or intermediate frequency (e.g., greater than 7.125 GHz). Similarly, unless otherwise stated, it should be understood that when the term "millimeter wave" or similar terms is used herein, it can broadly refer to frequencies within the EHF band, frequencies within FR2, and / or intermediate frequency band frequencies (e.g., less than 24.25 GHz). It is contemplated that the frequencies included in FR1 and FR2 can be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0042] As indicated above, Figure 1 This is provided as an example. Other examples may differ from those provided. Figure 1 As described. For example, network 100 may include any number of other types of devices and / or device arrangements, etc.

[0043] Figure 2This is a diagram illustrating an example 200 of a base station 110 communicating with a UE 120 in a wireless network 100 according to the present disclosure. The base station 110 may be equipped with T antennas 234a to 234t, and the UE 120 may be equipped with R antennas 252a to 252r, wherein typically T ≥ 1 and R ≥ 1.

[0044] At base station 110, transmitting processor 220 can receive data from one or more UEs from data source 212, select one or more modulation and coding schemes (MCS) for each UE based at least in part on channel quality indicators (CQI) received from the UE, process (e.g., encode and modulate) the UE's data based at least in part on the MCS selected for each UE, and provide data symbols for all UEs. Transmitting processor 220 can also process system information (e.g., for semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper-layer signaling), and provide overhead symbols and control symbols. Transmitting processor 220 can also 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., precoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols (if applicable), and can provide T output symbol streams to T modulators (MODs) 232a to 232t. Each modulator 232 can process its corresponding output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modulator 232 can also process (e.g., convert to analog, amplify, filter, and up-convert) the output sample stream to obtain a downlink signal. The T downlink signals from modulators 232a to 232t can be transmitted via T antennas 234a to 234t, respectively.

[0045] At UE 120, antennas 252a to 252r can receive downlink signals from base station 110 and / or other base stations, and can provide the received signals to demodulators (DEMODs) 254a to 254r respectively. Each demodulator 254 can adjust (e.g., filter, amplify, downconvert, and digitize) the received signal to obtain an input sample. Each demodulator 254 can also process the input sample (e.g., for OFDM) to obtain the received symbols. MIMO detector 256 can obtain the received symbols from all R demodulators 254a to 254r, perform MIMO detection on the received symbols (if applicable), and provide the detected symbols. Receive processor 258 can process (e.g., demodulate and decode) the detected symbols, provide the decoded data of UE 120 to data sink 260, and provide the decoded control information and system information to controller / processor 280. The term "controller / processor" can refer to one or more controllers, one or more processors, or a combination thereof. The channel processor can determine parameters such as the Received Reference Signal Power (RSRP), Received Signal Strength Indicator (RSSI), Received Reference Signal Quality (RSRQ), and / or CQI. In some respects, one or more components of the UE 120 may be included in the housing 284.

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

[0047] Antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include or be included within one or more antenna panels, antenna groups, antenna element sets, and / or antenna arrays. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include one or more antenna elements. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include coplanar antenna element sets and / or non-coplanar antenna element sets. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include antenna elements within a single housing and / or antenna elements within multiple housings. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include antenna elements coupled to one or more transmitting and / or receiving components (such as...) Figure 2 One or more antenna elements (one or more components).

[0048] On the uplink, at UE 120, the transmitting processor 264 can receive and process data from data source 262 and control information from controller / processor 280 (e.g., for reporting RSRP, RSSI, RSRQ, and / or CQI). The transmitting processor 264 can also generate reference symbols for one or more reference signals. Symbols from the transmitting processor 264 can be pre-coded (if applicable) by TX MIMO processor 266, and can also be processed by modulators 254a to 254r (e.g., for DFT-s-OFDM or CP-OFDM) and transmitted to base station 110. In some aspects, the modulator and demodulator of UE 120 (e.g., MOD / DEMOD 254) can be included in the modem of UE 120. In some aspects, UE 120 includes a transceiver. The transceiver may include any combination of antenna 252, modulator and / or demodulator 254, MIMO detector 256, receive processor 258, transmit processor 264 and / or TX MIMO processor 266. The processor (e.g., controller / processor 280) and memory 282 may be used with the transceiver to perform aspects of any of the methods described herein (e.g., as referenced). Figures 6-9 (As described).

[0049] At base station 110, uplink signals from UE 120 and other UEs can be received by antenna 234, processed by demodulator 232, detected by MIMO detector 236 (if applicable), and further processed by receiver processor 238 to obtain decoded data and control information transmitted by UE 120. Receiver processor 238 can provide decoded data to data sink 239 and decoded control information to controller / processor 240. Base station 110 may include communication unit 244 and communicate with network controller 130 via communication unit 244. Base station 110 may include scheduler 246 to schedule UE 120 for downlink and / or uplink communication. In some aspects, modulators and demodulators (e.g., MOD / DEMOD 232) of base station 110 may be included in the modem of base station 110. In some aspects, base station 110 includes transceivers. The transceiver may include any combination of antenna 234, modulator and / or demodulator 232, MIMO detector 236, receive processor 238, transmit processor 220, and / or TXMIMO processor 230. The processor (e.g., controller / processor 240) and memory 242 may be used with the transceiver to perform aspects of any of the methods described herein (e.g., as referenced). Figures 6-9 (As described).

[0050] The controller / processor 240 of base station 110, the controller / processor 280 of UE 120 and / or Figure 2Any other component may perform one or more techniques associated with enhanced duplex capability indication in integrated access and backhaul networks, as described in more detail elsewhere herein.

In some respects, the IAB node described herein is UE 120, is included in UE 120, or comprises... Figure 2 One or more components of the UE 120 shown herein, as described in more detail elsewhere. For example, the controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component can execute or direct, for example Figure 7 The process 700 Figure 8 The operation of process 800 and / or other processes described herein. Memory 242 and 282 may store data and program code of base station 110 and UE 120, respectively. In some aspects, memory 242 and / or memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, when one or more instructions are executed by one or more processors of base station 110 and / or UE 120 (e.g., directly, or after compilation, translation, and / or interpretation), they may cause one or more processors, UE 120, and / or base station 110 to perform or direct, for example...

[0053] In some aspects, an IAB node includes components for receiving an enhanced duplex capability indication indicating an enhanced duplex capability state associated with one or more resources; or for performing a wireless communication action at least in part based on the enhanced duplex capability indication. In some aspects, an IAB node includes components for receiving an access indication indicating an STC index associated with network access in one or more STC indices. In some aspects, an IAB node includes components for receiving an indication that the STC index associated with network access corresponds to a CD-SSB. In some aspects, an IAB node includes components for receiving a CD-SSB indicator indicating a CD-SSB associated with at least one of one or more configured SSB resources. In some aspects, an IAB node includes components for receiving a RACH indication indicating an STC index associated with RACH configuration in one or more STC indices.

[0054] In some aspects, components of an IAB node performing the operations described herein may include one or more of, for example, a transmit processor 220, a TX MIMO processor 230, a modulator 232, an antenna 234, a demodulator 232, a MIMO detector 236, a receive processor 238, a controller / processor 240, a memory 242, or a scheduler 246. In some aspects, components of an IAB node performing the operations described herein may include one or more of, for example, an antenna 252, a demodulator 254, a MIMO detector 256, a receive processor 258, a transmit processor 264, a TX MIMO processor 266, a modulator 254, a controller / processor 280, or a memory 282.

[0055] Although Figure 2 The blocks are shown as different components, but the functions described above for the blocks can be implemented in a single hardware, software, or combined component, or in various combinations of components. For example, the functions described for the transmit processor 264, receive processor 258, and / or TX MIMO processor 266 can be executed by or under the control of the controller / processor 280.

[0056] As indicated above, Figure 2 This is provided as an example. Other examples may differ from those provided. Figure 2 As described. For example, the UE and / or base station may include Figure 2Any number of other components not described in the text.

[0057] Figure 3 This is a diagram illustrating example 300 of a radio access network according to this disclosure.

[0058] As shown by reference numeral 305 in the accompanying drawings, a conventional (e.g., 3G, 4G, or LTE) radio access network may include multiple base stations 310 (e.g., access nodes (ANs)), each base station 310 communicating with the core network via a wired backhaul link 315 (such as a fiber optic connection). Base stations 310 may communicate with a UE 320 via an access link 325, which may be a radio link. In some aspects, Figure 3 The base station 310 shown can be Figure 1 The base station 110 is shown. In some respects, Figure 3 The UE 320 shown can be Figure 1 The UE 120 shown.

[0059] As indicated by reference numeral 330 in the attached figure, the radio access network may include a radio backhaul network, sometimes also referred to as an IAB network. In an IAB network, at least one base station is an anchor base station 335, which communicates with the core network via a wired backhaul link 340 (such as a fiber optic connection). The anchor base station 335 may also be referred to as an IAB donor (or IAB-donor). The IAB network may include one or more non-anchor base stations 345, sometimes referred to as relay base stations or IAB nodes (or IAB-nodes). Non-anchor base stations 345 may communicate directly or indirectly with the anchor base station 335 via one or more backhaul links 350 (e.g., via one or more non-anchor base stations 345) to form a backhaul path to the core network for carrying backhaul services. The backhaul link 350 may be a radio link. The anchor base station 335 and / or the non-anchor base station 345 may communicate with one or more UEs 355 via an access link 360, which may be a radio link for carrying access services. In some aspects, Figure 3 The anchor base station 335 and / or non-anchor base station 345 shown can be Figure 1 The base station 110 is shown. In some respects, Figure 3 The UE 355 shown can be Figure 1 The UE 120 shown.

[0060] As indicated by reference numeral 365 in the accompanying drawings, in some aspects, radio access networks, including IAB networks, can utilize millimeter-wave technology and / or directional communication (e.g., beamforming) for communication between base stations and / or UEs (e.g., between two base stations, between two UEs, and / or between a base station and a UE). For example, a wireless backhaul link 370 between base stations can use millimeter-wave signals to carry information and / or can use beamforming to be directed toward a target base station. Similarly, a wireless access link 375 between a UE and a base station can use millimeter-wave signals and / or can be directed toward a target wireless node (e.g., between a UE and / or a base station). This reduces inter-link interference.

[0061] Figure 3 The configuration of the base station and UE in the example is shown as an example, and other examples can be envisioned. For example, Figure 3 The one or more base stations shown can be replaced by one or more UEs communicating via a UE-to-UE access network (e.g., a peer-to-peer network or a device-to-device network). In this case, "anchor node" can refer to a UE that communicates directly with a base station (e.g., an anchor base station or a non-anchor base station).

[0062] As indicated above, Figure 3 This is provided as an example. Other examples may differ from those provided. Figure 3 As described. For example, any number of additional types of access networks can be conceived as... Figure 3 The access network interconnection is shown.

[0063] Figure 4 This is a diagram illustrating an example 400 of the IAB network architecture according to this disclosure.

[0064] like Figure 4 As shown, the IAB network may include an IAB donor 405 (shown as an IAB-donor) connected to the core network via a wired connection (shown as a wired backhaul). For example, the Ng interface of the IAB donor 405 may terminate in the core network. Additionally or alternatively, the IAB donor 405 may connect to one or more devices in the core network that provide core access and mobility management functions. In some aspects, the IAB donor 405 may include a base station 110, such as those described above. Figure 3The anchor base station is described above. As shown, the IAB donor 405 may include a central unit (CU) that can perform Access Node Controller (ANC) functions and / or Access and Mobility Management (AMF) functions. The CU can configure the distributed units (DUs) of the IAB donor 405 and / or can configure one or more IAB nodes 410 (e.g., the MTs and / or DUs of IAB nodes 410) connected to the core network via the IAB donor 405. Therefore, the CU of the IAB donor 405 can control and / or configure the entire IAB network connected to the core network via the IAB donor 405, such as by using control messages and / or configuration messages (e.g., Radio Resource Control (RRC) configuration messages or F1 Application Protocol (F1AP) messages).

[0065] like Figure 4 As also shown, the IAB network may include IAB nodes 410 (shown as IAB node 1, IAB node 2, and IAB node 3) connected to the core network via IAB donor 405. As illustrated, IAB node 410 may include Mobile Terminal (MT) functions (sometimes also referred to as UE functions (UEF)) and may include DU functions (sometimes also referred to as Access Node (ANF)). The MT function of IAB node 410 (e.g., a child node) may be controlled and / or scheduled by another IAB node 410 (e.g., the parent node of the child node) and / or IAB donor 405. The DU function of IAB node 410 (e.g., the parent node) may control and / or schedule other IAB nodes 410 (e.g., the child node of the parent node) and / or UE 120. Therefore, DU may be referred to as a scheduling node or scheduling component, while MT may be referred to as a scheduled node or scheduled component. In some aspects, IAB donor 405 may include DU functions but not MT functions. In other words, IAB donor 405 can configure, control, and / or schedule the communication of IAB node 410 and / or UE 120. UE 120 may include only MT functionality and not DU functionality. That is, the communication of UE 120 can be controlled and / or scheduled by IAB donor 405 and / or IAB node 410 (e.g., the parent node of UE 120).

[0066] When a first node controls and / or schedules the communication of a second node (e.g., when the first node provides DU functionality for the MT function of the second node), the first node can be referred to as the parent node of the second node, and the second node can be referred to as the child node of the first node. The child node of the second node can be referred to as the grandchild node of the first node. Therefore, the DU functionality of the parent node can control and / or schedule the communication of the child node of the parent node. The parent node can be an IAB donor 405 or an IAB node 410 (e.g., a base station), and the child node can be an IAB node 410 or a UE 120. The communication of the MT function of the child node can be controlled and / or scheduled by the parent node of that child node.

[0067] like Figure 4 As further illustrated, the link between UE 120 (e.g., having only MT functionality and not DU functionality) and IAB donor 405, or the link between UE 120 and IAB node 410, can be referred to as access link 415. Access link 415 can be a radio access link that provides radio access to the core network to UE 120 via IAB donor 405 and optionally via one or more IAB nodes 410. Therefore, Figure 4 The network shown can be called a multi-hop network or a wireless multi-hop network.

[0068] like Figure 4 As further illustrated, the link between IAB donor 405 and IAB node 410, or between two IAB nodes 410, can be referred to as backhaul link 420. Backhaul link 420 can be a wireless backhaul link that provides radio access to the core network to IAB node 410 via IAB donor 405 and optionally via one or more other IAB nodes 410. In the IAB network, network resources (e.g., time resources, frequency resources, and / or spatial resources) used for wireless communication can be shared between access link 415 and backhaul link 420. In some aspects, backhaul link 420 can be a primary backhaul link or a secondary backhaul link (e.g., a backup backhaul link). In some aspects, a secondary backhaul link can be used if the primary backhaul link fails, becomes congested, and / or becomes overloaded. For example, if the primary backhaul link between IAB node 2 and IAB node 1 fails, a backup link 425 between IAB node 2 and IAB node 3 can be used for backhaul communication. As used herein, and as indicated above, “node” or “wireless node” may refer to a base station, UE, IAB donor 405, or IAB node 410.

[0069] As indicated above, Figure 4 This is provided as an example. Other examples may differ from those provided. Figure 4As described. For example, an IAB network can include any number of levels and interconnections.

[0070] Figure 5 This is a diagram illustrating an example 500 of enhanced full-duplex in an IAB network according to the present disclosure. As shown, IAB node 510, IAB node 520, IAB node 530, and UE 540 can communicate within the IAB network. IAB node 510 can be the parent node of IAB node 520, and IAB node 520 can be the parent node of IAB node 530. UE 540 can be a child node of IAB node 520.

[0071] As shown by reference numeral 550, IAB node 520 can send communications to IAB node 510. As shown by reference numeral 560, IAB node 520 can send communications to IAB node 530, and as shown by reference numeral 570, IAB node 520 can send communications to UE 540. In some cases, IAB node 520 can send two or more communications simultaneously. In enhanced duplex mode, IAB node 520 can simultaneously operate as both the MT and DU of IAB node 520. For example, in enhanced duplex mode, the MT can send communications associated with reference numeral 550 to IAB node 510 while the DU sends communications associated with reference numeral 560 to IAB node 530 and / or communications associated with reference numeral 570 to UE 540. In cases where IAB node 520 is a base station such as a gNB (which may not have a co-located MT), the base station can support enhanced duplex mode. In such enhanced duplex mode, the base station can simultaneously transmit and / or receive two or more communications. For example, the base station can transmit communications to one UE and / or sub-node (e.g., UE 540) and simultaneously receive communications from another UE and / or sub-node (e.g., IAB node 530).

[0072] In another enhanced duplex configuration, the MT of IAB node 520 can simultaneously transmit communication (e.g., communication to IAB node 530 associated with reference numeral 560 and / or communication to UE 540 associated with reference numeral 570) and receive communication (e.g., from IAB node 510) at the same time as transmitting communication at the DU of IAB node 520 (e.g., communication to IAB node 530 and / or UE 540). In another enhanced duplex configuration, the MT of IAB node 520 can simultaneously receive communication (e.g., from IAB node 510) at the same time as receiving communication at the DU of IAB node 520 (e.g., from IAB node 530 and / or UE 540). In yet another enhanced duplex configuration, the MT of IAB node 520 can simultaneously transmit communication (e.g., to IAB node 510) at the same time as receiving communication at the DU of IAB node 520 (e.g., from IAB node 530 and / or UE 540).

[0073] In some cases, an IAB node can indicate to the CU whether it can support any of the four enhanced duplex scenarios. This information can also be provided by the CU to the parent node. However, this indication is typically static and unconditional. "Conditional enhanced duplex" can refer to the availability and / or capability of enhanced duplex with respect to one or more beams, the characteristics of one or more beams, the Random Access Channel (RACH) procedure, and / or aspects of the RACH procedure. Because the enhanced duplex indication does not take into account conditional enhanced duplex capability, devices may not be aware of such capability, and therefore enhanced duplex in an IAB network can be inefficient, potentially negatively impacting network performance.

[0074] The techniques and apparatus described herein can provide enhanced duplex capability indications that can indicate conditional capabilities. In some aspects, enhanced duplex capability indications can be transmitted using resource elements already specified in wireless communication standards. Therefore, these aspects can facilitate the provision of conditional enhanced duplex capability information between devices in an IAB network. Consequently, the techniques and apparatus described herein can improve the efficiency of enhanced duplexing in IAB networks, which can positively impact network performance.

[0075] For example, in some cases, STCs can be used to indicate SSB resources primarily used for configuration of inter-IAB node discovery and / or access procedures. For instance, a DU can send an STC indication to a CU or UE to indicate up to 5 STCs per serving cell (this can be indicated using the "IAB info IAB-DU" parameter in the "Served Cell Information" data field). A CU can send an STC indication to a DU to indicate up to 5 STCs per active cell of the IAB-DU (this can be indicated using the "IAB Info IAB-donor-CU" parameter in the "Cells to be Activated List" data field). A CU can send an STC indication to the parent node DU to indicate the STC configuration of the IAB node (this can be indicated using the "IAB STC Info" parameter in the "Child_Node Cells List" data field). Up to five STCs can be configured for a DU cell: one for access and four for backhaul. However, the usability of STCs for access is not yet defined. Therefore, the aspect described herein can utilize the STC designated for access to send enhanced duplex capability indications without unnecessarily increasing signaling overhead.

[0076] In some respects, the indication of SSB and / or STC indices can be used to refer to beams and / or beam-related characteristics, etc. In some respects, for example, the IAB DU can indicate to the CU one or more enhanced duplex capability states associated with one or more resources. One or more resources may include time resources, frequency resources, and / or spatial resources (e.g., beams, directions). The state can be indicated using a pair of values ​​(SSB index, STC index) associated with one of its serving cells. The state can indicate whether the IAB DU can support enhanced duplex scenarios, such as enhanced duplex scenarios with MT (e.g., UE) component carriers (CC). In some respects, for example, the above information can be shared by the CU and its parent node DU, or by the base station and the UE.

[0077] In some aspects, the IAB MT can use value pairs (SSB index, STC index) to indicate the status of one or more of its co-located DU cells (to the serving cell), which can indicate whether the IAB MT can support enhanced duplex with the parent node cell. In some aspects, the IAB node can use one or more status indicators (e.g., SSB index, STC index, DU cell index) of one or more beams in its beams to indicate the status. In some aspects, beams can be indicated using Transmission Configuration Indicator (TCI), TCI status, and / or Sounding Reference Signal Resource Indicator (SRI), etc.

[0078] In some respects, access STC indicators can be used to implicitly indicate a conditional enhanced duplex capability state. The identification of an access STC indicator can be explicit or implicit. For example, the first (or last) STC indicator in a list can be associated with access. In some respects, an STC indicator associated with access can be associated with one or more cell-defined SSBs (CD-SSBs). In some respects, an STC indicator with "SSB frequency information" matching one of the synchronization grid frequencies can be assumed to be associated with access and / or a CD-SSB.

[0079] In some respects, enhanced duplex capability indications can be associated with RACH capability. For example, when an IAB node reports its STC indicator to another IAB node (e.g., to the CU or UE), it can indicate which STC indicator is associated with RACH. In some respects, an IAB node can indicate which RACH timing (e.g., during a RACH period) can or cannot support enhanced duplex with MTCC.

[0080] As indicated above, Figure 5 This is provided as an example. Other examples may differ from those provided. Figure 5 As described. For example, any number of other devices and / or IAB nodes can participate in full-duplex simultaneously.

[0081] Figure 6 This is a diagram illustrating an example 600 associated with an enhanced duplex capability indication in an IAB network according to this disclosure. Figure 6 As shown, IAB nodes 605, 610, and 615 can communicate within the IAB network. In some aspects, IAB node 605 can represent the parent node of IAB node 610, and IAB node 615 can represent a CU. In some aspects, IAB node 605 can represent a base station (e.g., a gNB), IAB node 610 can represent a UE, and IAB node 615 can represent a CU. In some aspects, IAB node 605 can represent a UE, IAB node 610 can represent a base station (e.g., a gNB), and IAB node 615 can represent a CU.

[0082] As shown by reference numeral 620, IAB node 605 can transmit and IAB node 610 can receive an enhanced duplex capability indication indicating the enhanced duplex capability status associated with one or more resources. In some aspects, the one or more resources may include frequency resources, time resources, and / or spatial resources. In some aspects, the one or more resources may include one or more beams associated with a serving cell. As shown by reference numeral 625, IAB node 610 can transmit the enhanced duplex capability indication to IAB node 615. For example, IAB node 610 may be a CU and may transmit the enhanced duplex capability indication received from the DU (IAB node 605) to the parent node (IAB node 615) of the DU.

[0083] In some aspects, one or more resources may include one or more configured SSB resources. For example, an enhanced duplex capability indication may indicate one or more configured SSB resources based at least in part on indications of one or more SSB indices associated with the serving cell. In some aspects, an enhanced duplex capability indication may indicate one or more configured SSB resources based at least in part on indications of one or more STC indices associated with at least one of the one or more SSB indices. For example, in some aspects, an IAB DU may indicate to a CU one or more indices (e.g., SSB index, STC index) associated with one of its serving cells to indicate whether it is able (or unable) to support enhanced duplex conditions.

[0084] In some aspects, IAB node 605 may send an access indication that refers to an STC index associated with network access in one or more STC indices. For example, the IAB node may be a DU, in which case sending the access indication may include sending the access indication to the CU. In some aspects, IAB node 605 may include a CU, wherein sending the access indication may include sending the access indication to the DU and / or the parent node. In some aspects, the access indication may include an implicit indication. For example, sending an implicit indication may include sending a list of one or more STC indices, wherein the STC index associated with network access may include the first STC index of the list or the last STC index of the list.

[0085] In some respects, the STC index associated with network access can correspond to a CD-SSB. For example, IAB node 605 can send an indication that the STC index associated with network access corresponds to a CD-SSB. In other respects, the STC index associated with network access can correspond to SSB frequency information that matches the synchronization grid frequency.

[0086] In some aspects, IAB node 605 can send a (RACH) indication that is associated with one or more STC indices in the RACH configuration. For example, IAB node 605 can be a DU and can send a RACH indication to a CU. In some aspects, IAB node 605 can be a DU and can send a RACH indication to a CU. In some aspects, IAB node 605 can be a CU and can send a RACH indication to the parent node of the DU. IAB node 605 can receive RACH indications from the DU.

[0087] In some aspects, IAB node 605 may include a DU, and the enhanced duplex capability indication may indicate one or more configured SSB resources associated with a serving cell for which the DU can support enhanced duplexing with the MT CC. IAB node 605 may also be a CU, and the enhanced duplex capability indication may indicate one or more configured SSB resources associated with a serving cell for which the DU can support enhanced duplexing with the MT CC. In some aspects, sending the enhanced duplex capability indication may include sending the enhanced duplex capability indication to the parent node DU of the DU.

[0088] IAB node 605 can be MT, and the enhanced duplex capability indication can indicate that the co-located DU is capable of supporting one or more configured SSB resources associated with the serving cell of the parent node of the MT for enhanced duplexing, wherein the co-located DU serves the serving cell. IAB node 605 can send this indication to the parent node.

[0089] In some respects, the enhanced duplex capability indicator can indicate that the co-located DU is capable of supporting enhanced duplexing with the MT's parent node, associated with one or more beams. The enhanced duplex capability indicator can indicate at least one of the following: an SSB index associated with one or more configured SSB resources, an STC index associated with one or more configured SSB resources, a DU cell index associated with the serving cell, a TCI state associated with one or more beams, and / or an SRI associated with one or more beams, etc.

[0090] In some aspects, IAB 605 can send a CD-SSB indicator that indicates a CD-SSB associated with at least one of one or more configured SSB resources. The one or more resources may include one or more RACH moments within a RACH period. In some aspects, an enhanced duplex capability indicator indicates one or more RACH moments within a RACH period that can support enhanced duplexing with MT CC.

[0091] As shown by reference numeral 630 in the attached figure, IAB node 605 and IAB node 610 can communicate via the IAB network, at least in part, based on resources in one or more of the resources.

[0092] As indicated above, Figure 6 This is provided as an example. Other examples may differ from those provided. Figure 6 As described. For example, enhanced duplex capability indicators can be associated with any number of other conditions and / or characteristics of the communication configuration.

[0093] Figure 7 This is a diagram illustrating an example process 700 performed, for example, by an IAB node according to this disclosure. Example process 700 is an example of an IAB node (e.g., IAB node 605) performing operations associated with an enhanced duplex capability indication in an IAB network.

[0094] like Figure 7 As shown, in some aspects, process 700 may include sending an enhanced duplex capability indication (box 710) that indicates the enhanced duplex capability status associated with one or more resources. For example, as described above, an IAB node (e.g., using...) Figure 9 The sending component 904 depicted in the figure can send an enhanced duplex capability indication that indicates the enhanced duplex capability status associated with one or more resources.
