[Technical field]

[0002] Aspects of the present disclosure relate generally to wireless communications and to techniques and apparatus for simultaneous communication capability signaling in integrated access and backhaul networks. [Background technology]

[0003]

[0003] Wireless communication systems have been widely deployed to provide various telecommunication services, such as telephone, video, data, messaging, and broadcast. A typical wireless communication system may employ multiple access technologies capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access technologies include Code Division Multiple Access (CDMA) systems, Time Division Multiple Access (TDMA) systems, Frequency Division Multiple Access (FDMA) systems, Orthogonal Frequency Division Multiple Access (OFDMA) systems, Single Carrier Frequency Division Multiple Access (SC-FDMA) systems, Time Division Synchronous Code Division Multiple Access (TD-SCDMA) systems, and Long Term Evolution (LTE). LTE / LTE-Advanced is a set of extensions to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the 3rd Generation Partnership Project (3GPP).

[0004] A wireless communication network may include several base stations (BSs) that can support communication for several user equipments (UEs). The user equipments (UEs) may communicate with the base stations (BSs) via a downlink and an uplink. The downlink (or forward link) refers to the communication link from the BS to the UE, and the uplink (or reverse link) refers to the communication link from the UE to the BS. As described in more detail herein, a BS may be referred to as a Node B, a gNB, an access point (AP), a radio head, a transmit / receive point (TRP), a new radio (NR) BS, a 5G Node B, etc.

[0005]

[0005] The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that allows different user equipment to communicate on a city, national, regional, or even global scale. New Radio (NR), sometimes referred to as 5G, is a set of extensions to the LTE mobile standard promulgated by the Third Generation Partnership Project (3GPP). NR is designed to better support mobile broadband Internet access by improving spectral efficiency, lowering costs, improving services, utilizing new spectrum, and better integrating with other open standards using Orthogonal Frequency Division Multiplexing (OFDM) with Cyclic Prefix (CP) (CP-OFDM) on the downlink (DL) and CP-OFDM and / or SC-FDM (also known as Discrete Fourier Transform Spread OFDM (DFT-s-OFDM) on the uplink (UL), as well as supporting beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation. However, as demand for mobile broadband access continues to grow, further improvements to LTE and NR technologies are needed, and preferably these improvements should be applicable to other multiple access technologies and the telecommunications standards that employ these technologies.

[0018]

[0024] Various aspects of the present disclosure are described more fully below 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 particular structure or function presented throughout the present disclosure. Instead, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. Based on the teachings herein, one skilled in the art should appreciate that the scope of the present disclosure encompasses any aspect of the present disclosure disclosed herein, whether implemented independently of or in combination with other aspects of the present disclosure. For example, an apparatus may be implemented or a method may be practiced using any number of the aspects described herein. In addition, the scope of the present disclosure encompasses an apparatus or method practiced using other structures, functions, or structures and functions in addition to or other than the various aspects of the present disclosure described herein. It should be understood that any aspect of the disclosure disclosed herein may be embodied by one or more elements of a claim.

[0019]

[0025] Several aspects of a telecommunications system are now presented with reference to various apparatus and techniques that are described in the detailed description that follows and illustrated in the accompanying 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 such elements are implemented as hardware or software depends on the particular application and design constraints imposed on the overall system.

[0020]

[0026] It should be noted that although aspects may be described herein using terminology commonly associated with 3G and / or 4G wireless technology, aspects of the present disclosure may be applied in other generation-based communication systems, such as 5G and beyond, including NR technology.

[0021]

[0027] FIG. 1 illustrates a wireless network 100 in which aspects of the disclosure may be practiced. The wireless network 100 may be an LTE network or some other wireless network, such as a 5G or NR network. The wireless network 100 may include several BSs 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d) and other network entities. A BS is an entity that communicates with user equipment (UE) and may also be referred to as a base station, NR BS, Node B, gNB, 5G Node B (NB), access point, transmit / receive point (TRP), etc. Each BS may provide communication coverage for a particular geographic area. In 3GPP, the term "cell" can refer to a coverage area of ​​a BS and / or a BS subsystem serving this coverage area, depending on the context in which the term is used.

[0022]

[0028] A BS may provide communication coverage for a macro cell, a pico cell, a femto cell, and / or another type of cell. A macro cell may cover a relatively large geographic area (e.g., a few kilometers in radius) and may allow unrestricted access by UEs with a service subscription. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs with a service subscription. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by UEs having an association with the femto cell (e.g., UEs in a Closed Subscriber Group (CSG)). A BS for a macro cell may be referred to as a macro BS. A BS for a pico cell may be referred to as a pico BS. A BS for a femto cell may be referred to as a femto BS or a home BS. 1, BS 110a may be a macro BS for a macro cell 102a, BS 110b may be a pico BS for a pico cell 102b, and BS 110c may be a femto BS for a femto cell 102c. A BS may support one or multiple (e.g., three) cells. The terms “eNB,” “base station,” “NR BS,” “gNB,” “TRP,” “AP,” “Node B,” “5G NB,” and “cell” may be used interchangeably herein.

[0023]

[0029] In some aspects, the cells may not necessarily be fixed and the geographic area of ​​the cells may move according to the location of the mobile BS. In some aspects, the BSs may be interconnected to each other and / or to one or more other BSs or network nodes (not shown) in wireless network 100 through various types of backhaul interfaces, such as direct physical connections, virtual networks, etc., using any suitable transport network.

[0024]

[0030] The wireless network 100 may also include relay stations. A relay station is an entity that can receive a transmission of data from an upstream station (e.g., a BS or a UE) and send the transmission of the data to a downstream station (e.g., a UE or a BS). A relay station may also be a UE that can relay a transmission for another UE. In the example shown in FIG. 1, a relay BS 110d may communicate with a macro BS 110a and a UE 120d to enable communication between the BS 110a and the UE 120d. A relay BS may also be referred to as a relay station, a relay base station, a relay, etc.

[0025]

[0031] The wireless network 100 may be a heterogeneous network including different types of BSs, e.g., macro BSs, pico BSs, femto BSs, relay BSs, etc. These different types of BSs may have different transmit power levels, different coverage areas, and different impacts on interference in the wireless network 100. For example, a macro BS may have a high transmit power level (e.g., 5-40 watts), while a pico BS, femto BS, and relay BS may have a lower transmit power level (e.g., 0.1-2 watts).

[0026]

[0032] A network controller 130 may couple to a set of BSs and provide coordination and control for these BSs. The network controller 130 may communicate with the BSs via a backhaul. The BSs may also communicate with each other directly or indirectly, for example, via a wireless or wireline backhaul.

[0027]

[0033] The UEs 120 (e.g., 120a, 120b, 120c) may be dispersed 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, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device or equipment, a biometric sensor / device, a wearable device (smart watch, 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 global positioning system device, or any other suitable device configured to communicate over a wireless or wired medium.

[0028]

[0034] Some UEs may be considered as machine type communication (MTC) UEs or evolved or enhanced machine type communication (eMTC) UEs. MTC UEs and eMTC UEs include, for example, a robot, a drone, a remote device, a sensor, a meter, a monitor, a location tag, etc., that may communicate with a base station, another device (e.g., a remote device), or some other entity. A wireless node may provide, for example, connectivity for or to a network (e.g., a wide area network such as the Internet or a cellular network) via a wired or wireless communication link. Some UEs may be considered as Internet of Things (IoT) devices and / or implemented as NB-IoT (narrowband Internet of Things) devices. Some UEs may be considered as customer premises equipment (CPE). The UE 120 may be included in a housing that stores components of the UE 120, such as a processor component, a memory component, etc.

[0029]

[0035] Generally, any number of wireless networks may be deployed in a given geographic area. Each wireless network may support a particular radio access technology (RAT) and may operate on one or more frequencies. The RAT may also be referred to as a radio technology, an air interface, etc. The frequencies may also be referred to as a carrier, a frequency channel, etc. Each frequency may support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed.

[0030]

[0036] In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly (e.g., without using a base station 110 as an intermediary to communicate with each other) using one or more sidelink channels. For example, the UEs 120 may communicate using peer-to-peer (P2P) communications, device-to-device (D2D) communications, vehicle-to-everything (V2X) protocols (which may include, e.g., vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, etc.), mesh networks, etc. In this case, the UEs 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by the base station 110.

[0031]

[0037] As noted above, Figure 1 is provided as an example. Other examples may differ from those described with respect to Figure 1.

[0032]

[0038] 2 shows a block diagram of a design 200 of a base station 110, which may be one of the base stations in FIG. 1, and a UE 120, which may be one of the UEs in FIG. 1. Base station 110 may be equipped with T antennas 234a through 234t, and UE 120 may be equipped with R antennas 252a through 252r, where in general, T≧1 and R≧1.

[0033]

[0039] At the base station 110, the transmit processor 220 may receive data from a data source 212 for one or more UEs, select one or more modulation and coding schemes (MCS) for each UE based at least in part on a channel quality indicator (CQI) received from the UE, process (e.g., encode and modulate) the data for each UE based at least in part on the MCS selected for that UE, and provide data symbols for all UEs. The transmit processor 220 may also process system information (e.g., for semi-static resource partitioning information (SRPI), etc.) and control information (e.g., CQI requests, grants, higher layer signaling, etc.) and provide overhead symbols and control symbols. The transmit processor 220 may also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS)) and synchronization signals (e.g., primary synchronization signals (PSS) and secondary synchronization signals (SSS)). A 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 T output symbol streams to T modulators (MODs) 232a through 232t. Each modulator 232 may process a respective output symbol stream (e.g., for OFDM, etc.) to obtain an output sample stream. Each modulator 232 may further process (e.g., convert to analog, amplify, filter, and upconvert) the output sample stream to obtain a downlink signal. The T downlink signals from the modulators 232a through 232t may be transmitted via T antennas 234a through 234t, respectively. According to various aspects described in more detail below, a synchronization signal may be generated using location coding to convey additional information.

[0034]

[0040] At the UE 120, the antennas 252a-252r may receive downlink signals from the base station 110 and / or other base stations and may provide received signals to demodulators (DEMODs) 254a-254r, respectively. Each demodulator 254 may condition (e.g., filter, amplify, downconvert, and digitize) the received signal to obtain input samples. Each demodulator 254 may further process the input samples (e.g., for OFDM, etc.) to obtain received symbols. A MIMO detector 256 may obtain received symbols from all R demodulators 254a-254r, perform MIMO detection on the received symbols if applicable, and provide detected symbols. A receive processor 258 may process (e.g., demodulate and decode) the detected symbols, provide decoded data for the UE 120 to a data sink 260, and provide decoded control and system information to the controller / processor 280. The channel processor may determine a reference signal received power (RSRP), a received signal strength indicator (RSSI), a reference signal received quality (RSRQ), a channel quality indicator (CQI), etc. In some aspects, one or more components of the UE 120 may be included in a housing.

[0035]

[0041] On the uplink, at the UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information (e.g., for reports comprising RSRP, RSSI, RSRQ, CQI, etc.) from the controller / processor 280. The transmit processor 264 may also generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be precoded by a TX MIMO processor 266 if applicable, further processed by modulators 254a-254r (e.g., for DFT-s-OFDM, CP-OFDM, etc.), and transmitted to the base station 110. At the base station 110, uplink signals from the UE 120 and other UEs may be received by antennas 234, processed by a demodulator 232, detected by a MIMO detector 236 if applicable, and further processed by a receive processor 238 to obtain decoded data and control information sent by the UE 120. The receive processor 238 may provide the decoded data to a data sink 239 and may provide the decoded control information to the controller / processor 240. The base station 110 may include a communication unit 244 and may communicate to the network controller 130 via the communication unit 244. The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292.

[0036]

[0042] The controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or any other components of FIG. 2 may implement one or more techniques related to simultaneous communication capability signaling in an integrated access and backhaul (IAB) network, as described in more detail elsewhere herein. Additionally or alternatively, a node in an IAB network (e.g., an IAB node, an IAB donor, a control node, a child node, a parent node, etc.) and / or a node in another type of wireless multi-hop network may implement one or more techniques related to simultaneous communication capability signaling in an IAB network. As described in more detail elsewhere herein, such a node may include a mobile termination or mobile terminal (MT) component and a distributed unit (DU) component. Additionally or alternatively, a node (e.g., an IAB donor) may include a central unit (CU) component and a DU component. The MT component may perform one or more functions of the UE 120 described herein (e.g., with respect to FIGS. 1-3) and / or may include one or more components of the UE 120 described herein (e.g., with respect to FIG. 2). The DU component may perform one or more functions of the base station 110 described herein (e.g., with respect to FIGS. 1-3) and / or may include one or more components of the base station 110 described herein (e.g., with respect to FIG. 2), such as scheduling. The CU component may perform one or more functions of the base station 110 described herein (e.g., with respect to FIGS. 1-3) and / or may include one or more components of the base station 110 described herein (e.g., with respect to FIG. 2), such as configuration for other nodes.

[0037]

[0043] In some aspects, the controller / processor 240 of the base station 110 and / or the node, the controller / processor 280 of the UE 120 and / or the node, and / or any other components of FIG. 2 may perform or direct operations, for example, of process 1000 of FIG. 10, process 1100 of FIG. 11, and / or other processes described herein. The memories 242 and 282 may store data and program codes for the base station 110 and the UE 120, respectively. In some aspects, the memory 242 and / or the memory 282 may comprise a non-transitory computer-readable medium that stores one or more instructions for wireless communication. For example, the one or more instructions, when executed by one or more processors of the base station 110 and / or the UE 120, may perform or direct operations, for example, of process 1000 of FIG. 10, process 1100 of FIG. 11, and / or other processes described herein. The scheduler 246 may schedule UEs for data transmission on the downlink and / or uplink.

[0038]

[0044] In some aspects, a node may include means for transmitting an indication of the node's capabilities for simultaneous communication with respect to at least one of the node's parent nodes, the node's mobile termination components, the node's transmission / reception points, the node's cells, or a combination thereof, and means for communicating with another node in a wireless network based at least in part on the capabilities, etc. In some aspects, such means may include one or more components of a UE 120 and / or a base station 110 (which may be included in the node) described with respect to FIG.

[0039]

[0040]

[0046] As noted above, Figure 2 is provided as an example. Other examples may differ from those described with respect to Figure 2.

[0041]

[0047] FIG. 3 is a diagram illustrating an example wireless access network 300 in accordance with various aspects of the present disclosure.

[0042]

[0048] As indicated by reference numeral 305, a conventional (e.g., 3G, 4G, LTE, etc.) wireless access network may include multiple base stations 310 (e.g., access nodes (ANs)), where each base station 310 communicates with a core network via a wired backhaul link 315, such as a fiber connection. The base stations 310 may communicate with a UE 320 via an access link 325, which may be a wireless link. In some aspects, the base station 310 shown in FIG. 3 may be the base station 110 shown in FIG. 1. In some aspects, the UE 320 shown in FIG. 3 may be the UE 120 shown in FIG. 1.

[0043]

[0049] As indicated by reference numeral 330, the radio access network may include a wireless backhaul network, which may be referred to as an IAB network. In an IAB network, at least one base station is an anchor base station 335 that communicates with a core network via a wired backhaul link 340, such as a fiber 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, which may be referred to as relay base stations or IAB nodes (or IAB-nodes). The non-anchor base stations 345 may communicate directly or indirectly with the anchor base station 335 (e.g., via one or more non-anchor base stations 345) via one or more backhaul links 350 to form a backhaul path to the core network for carrying backhaul traffic. The backhaul link 350 may be a wireless link. The anchor base station(s) 335 and / or the non-anchor base station(s) 345 may communicate with one or more UEs 355 via an access link 360, which may be a wireless link for carrying access traffic. In some aspects, the anchor base station 335 and / or the non-anchor base station 345 shown in Figure 3 may be the base station 110 shown in Figure 1. In some aspects, the UE 355 shown in Figure 3 may be the UE 120 shown in Figure 1 and / or Figure 2.

[0044]

[0050] As indicated by reference numeral 365, in some aspects, a radio access network including an IAB network may utilize millimeter wave technology and / or directional communications (e.g., beamforming, etc.) for communications 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 may use millimeter wave signals to carry information and / or may be directed toward a target base station using beamforming, etc. Similarly, a wireless access link 375 between a UE and a base station may use millimeter wave signals and / or may be directed toward a target wireless node (e.g., a UE and / or a base station). In this manner, interlink interference may be reduced.

[0045]

[0051] The configuration of base stations and UEs in Figure 3 is shown as an example, and other examples are contemplated. For example, one or more base stations shown in Figure 3 may be replaced with one or more UEs that communicate via a UE-to-UE access network (e.g., a peer-to-peer network, a device-to-device network, etc.). In this case, an anchor node may refer to a UE that is in direct communication with a base station (e.g., an anchor base station or a non-anchor base station).

[0046]

[0052] As noted above, Figure 3 is provided as an example. Other examples may differ from those described with respect to Figure 3.

[0047]

[0053] FIG. 4 is a diagram illustrating an example IAB network architecture 400 in accordance with various aspects of the present disclosure.

[0048]

[0054] As shown in FIG. 4, the IAB network may include an IAB donor 405 (depicted as IAB-donor) that connects to a core network via a wired connection (depicted as wireline 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 of the core network that provide core access and mobility management functions (e.g., AMF). In some aspects, the IAB donor 405 may include a base station 110, such as an anchor base station, as described above with respect to FIG. 3. As shown, the IAB donor 405 may include a central unit (CU), which may perform access node controller (ANC) functions, AMF functions, and the like. The CU may configure a distributed unit (DU) of the IAB donor 405 and / or one or more IAB nodes 410 (e.g., MTs and / or DUs of the IAB node 410) that connect to the core network via the IAB donor 405. Thus, the CU of the IAB donor 405 may control and / or configure the entire IAB network that connects 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, F1 Application Protocol (F1AP) messages, etc.).

[0049]

[0055] As further illustrated in FIG. 4, the IAB network may include IAB nodes 410 (shown as IAB-node 1, IAB-node 2, and IAB-node 3) that connect to a core network via an IAB donor 405. As illustrated, the IAB nodes 410 may include a mobile terminated (MT) function (sometimes referred to as a UE function (UEF)) and a DU function (sometimes referred to as an access node function (ANF)). The MT function of an IAB node 410 (e.g., a child node) may be controlled and / or scheduled by another IAB node 410 (e.g., a parent node of a child node) and / or by the IAB donor 405. The DU function of an IAB node 410 (e.g., a parent node) may control and / or schedule other IAB nodes 410 (e.g., a child node of a parent node) and / or UEs 120. Thus, a DU may be referred to as a scheduling node or scheduling component, and a MT may be referred to as a scheduled node or scheduled component. In some aspects, the IAB donor 405 may include DU functionality but not MT functionality. That is, the IAB donor 405 may configure, control, and / or schedule communications of the IAB node 410 and / or the UE 120. The UE 120 may include only MT functionality and not DU functionality. That is, communications of the UE 120 may be controlled and / or scheduled by the IAB donor 405 and / or the IAB node 410 (e.g., a parent node of the UE 120).

[0050]

[0056] When a first node controls and / or schedules communications for a second node (e.g., when the first node provides a DU function for the MT function of the second node), the first node may be referred to as a parent node of the second node, and the second node may be referred to as a child node of the first node. The child node of the second node may be referred to as a grandchild node of the first node. Thus, the DU function of the parent node may control and / or schedule communications for the child node of the parent node. The parent node may be an IAB donor 405 or an IAB node 410, and the child node may be an IAB node 410 or a UE 120. The communications of the MT function of the child node may be controlled and / or scheduled by the parent node of the child node.

[0051]

[0057] 4, the link between the UE 120 (e.g., having only MT capabilities and no DU capabilities) and the IAB donor 405, or the link between the UE 120 and the IAB node 410, may be referred to as an access link 415. The access link 415 may be a wireless access link that provides the UE 120 with wireless access to the core network via the IAB donor 405 and possibly via one or more IAB nodes 410. Thus, the network illustrated in FIG. 4 may be referred to as a multi-hop network or a wireless multi-hop network.

[0052]

[0058] As further illustrated in FIG. 4, a link between an IAB donor 405 and an IAB node 410, or a link between two IAB nodes 410, may be referred to as a backhaul link 420. The backhaul link 420 may be a wireless backhaul link that provides the IAB node 410 with wireless access to a core network via the IAB donor 405 and possibly via one or more other IAB nodes 410. In some aspects, the backhaul link 420 may be a primary backhaul link or a secondary backhaul link (e.g., a backup backhaul link). In some aspects, the secondary backhaul link may be used in cases where the primary backhaul link does not function, becomes congested, becomes overloaded, etc. For example, if the primary backhaul link between IAB-node 2 and IAB-node 1 does not function, the backup link 425 between IAB-node 2 and IAB-node 3 may be used for backhaul communication. As used herein, a node or a wireless node may refer to an IAB donor 405 or an IAB node 410.

[0053]

[0059] In an IAB network, network resources (e.g., time resources, frequency resources, spatial resources, etc.) for wireless communications may be shared between the access link 415 and the backhaul link 420. In some cases, a CU of an IAB donor 405 may configure a resource pattern for an IAB node 410 in an IAB network. For example, a time resource may be configured as downlink only, uplink only, flexible, unavailable (e.g., unavailable). When a time resource is configured as downlink only for a wireless node, the time resource may be available only for downlink communications of the wireless node, but not available for uplink communications. Similarly, when a time resource is configured as uplink only for a wireless node, the time resource may be available only for uplink communications of the wireless node, but not available for downlink communications. When a time resource is configured as flexible for a wireless node, the time resource may be available for both downlink and uplink communications of the wireless node. When a time resource is configured as unavailable for a wireless node, the time resource may not be used for any communications of the wireless node.

[0054]

[0060] A time resource in an IAB network configured as downlink-only, uplink-only, or flexible may be further configured as a hard resource or a soft resource. When a time resource is configured as a hard resource for a wireless node, the time resource is always available for the wireless node's communications. For example, a hard downlink-only time resource is always available for the wireless node's downlink communications only, a hard uplink-only time resource is always available for the wireless node's uplink communications only, and a hard flexible time resource is always available for the wireless node's uplink and downlink communications.

[0055]

[0061] When a time resource is configured as a soft resource for a wireless node, the availability of the time resource is controlled by the parent node of the wireless node (e.g., by the DU of the parent node). For example, the parent node may indicate (e.g., explicitly or implicitly) whether the soft time resource is available for the wireless node's communication. Thus, the soft time resource may be in one of two states: a schedulable state (e.g., the soft time resource is available for the wireless node's scheduling and / or communication) and a non-schedulable state (e.g., the soft time resource is not available for scheduling and is not available for the wireless node's communication). For example, when the parent node of the wireless node indicates that a soft downlink-only time resource is available, the soft downlink-only time resource is available only for the wireless node's downlink communication. Similarly, when the parent node of the wireless node indicates that a soft uplink-only time resource is available, the soft uplink-only time resource is available only for the wireless node's uplink communication. When a parent node of a wireless node indicates that a soft flexible time resource is available, the soft flexible time resource is available only for uplink and downlink communications of the wireless node.

[0056]

[0062] In some cases, nodes of an IAB network are subject to a half-duplex constraint, meaning that a particular node cannot transmit and receive information at the same time (e.g., cannot communicate concurrently or simultaneously over the node's access link 415 and the node's backhaul link 420). This constraint may lead to high latency of communication. To enable communication over both the node's access link 415 and backhaul link 420, the node may be configured with resource allocations using time division multiplexing (TDM), where communications on the access link 415 and backhaul link 420 are scheduled to occur at different times. However, this may increase the latency of communication as compared to simultaneous communication over the access link 415 and backhaul link 420.

[0057]

[0063] In some cases, to reduce latency and / or improve reliability, an IAB node (e.g., a child node) may communicate with multiple parent nodes via corresponding multiple backhaul links 420. In some cases, multiple backhaul links 420 are actively used to communicate, and if one of the backhaul links 420 does not function, none of the backhaul links 420 are used as a backup link 425. However, if TDM is used across multiple backhaul links 420 and one or more access links 415, latency may increase if simultaneous communication is not enabled across the multiple links. Some techniques and apparatus described herein enable an IAB node to communicate simultaneously over multiple links, such as multiple backhaul links 420, multiple access links 415, or one or more backhaul links 420 and one or more access links 415.

[0058]

[0064] However, different IAB nodes may have different capabilities for simultaneous communication depending on the architecture and / or hardware configuration of the IAB node, such as whether the IAB node supports full-duplex communication, the level of self-interference generated by the IAB node's transmissions, the IAB node's ability to mitigate and / or cancel such self-interference (e.g., using filtering), the number of transmit and / or receive chains of the IAB node, whether such transmit and / or receive chains are shared by multiple antennas of the IAB node, the operating frequency or bandwidth of the IAB node, the beamforming capability or configuration of the IAB node, etc. Additionally, different IAB nodes may have different capabilities for simultaneous communication depending on the network conditions and / or transmission parameters of the simultaneous communication, such as a beamforming direction associated with the simultaneous communication, the transmit power of the simultaneous communication, whether such simultaneous communication is synchronized, the frequency of cells through which the IAB node may communicate, etc. Some techniques and apparatus described herein enable an IAB node to signal its capability for simultaneous communication over multiple links, which may be subject to one or more conditions. In this manner, the IAB nodes can reduce latency, improve reliability, improve spectral efficiency, etc. by utilizing the IAB nodes' capabilities for simultaneous communication.

[0059]

[0065] As noted above, Figure 4 is provided as an example. Other examples may differ from those described with respect to Figure 4.

[0060]

[0066] FIG. 5 illustrates an example 500 of simultaneous communication capability signaling in an IAB network, according to various aspects of the disclosure. As illustrated in FIG. 5, the IAB network may include an IAB donor 405 and one or more IAB nodes 410, illustrated as a first IAB node 410-1, which is a child node of both a second IAB node 410-2 and a third IAB node 410-3. Hereinafter, the first IAB node 410-1 is referred to as a child node, the second IAB node 410-2 is referred to as a first parent node (illustrated as parent node 1 or P1), and the third IAB node 410-3 is referred to as a second parent node (illustrated as parent node 2 or P2). Although the child nodes are illustrated as IAB nodes, in some aspects, the child nodes may be UEs 120.

[0061]

[0067] As indicated by reference numeral 505, the child node may determine the child node's capability for simultaneous communication. The capability may be the capability for simultaneous communication with multiple parent nodes of the child node, multiple MT components of the child node, and / or multiple TRPs of the child node. For example, in some aspects, the capability may include the capability for simultaneous communication with multiple parent nodes of the child node, as described in more detail below with respect to FIG. 6. Additionally or alternatively, the capability may be the capability for simultaneous communication using multiple MT components of the child node, as described in more detail below with respect to FIG. 7. Additionally or alternatively, the capability may be the capability for simultaneous communication using multiple TRPs of the child node, as described in more detail below with respect to FIG. 8.

[0062]

[0068] In some aspects, the capability is for simultaneous communication using different or multiple RATs. For example, a child node may indicate capability for simultaneous communication using a dual connectivity mode using two RATs, such as an Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access (E-UTRA) New Radio (NR) Dual Connectivity (EN-DC) mode or an NR E-UTRA Dual Connectivity (NE-DC) mode. Additionally or alternatively, the capability may be for simultaneous communication using a single RAT. For example, the capability may be for simultaneous communication using only the NR RAT.

[0063]

[0069] In some aspects, the capability for simultaneous communication may be subject to conditions. In some aspects, the child node may determine and / or identify the conditions. Additionally or alternatively, the child node may determine whether the capability for simultaneous communication is conditional (e.g., subject to conditions) or unconditional (e.g., not subject to conditions). In some aspects, the conditions may depend on the architecture and / or hardware configuration of the child node, such as whether the child node supports full-duplex communication, the level of self-interference generated by the transmission of the child node, the ability of the child node to mitigate and / or cancel such self-interference, the number of transmit and / or receive chains of the child node, whether such transmit and / or receive chains are shared by multiple antennas of the child node, etc. Additionally or alternatively, the conditions may depend on network conditions and / or transmission parameters associated with the simultaneous communication, such as beamforming directions associated with the simultaneous communication, transmit powers of the simultaneous communication, whether such simultaneous communication is synchronized, etc.

[0064]

[0070] In some aspects, the condition may depend on a transmit power associated with the one or more simultaneous communications, a receive power associated with the one or more simultaneous communications, a transmit timing associated with the one or more simultaneous communications, a receive timing associated with the one or more simultaneous communications, a resource allocation (e.g., a time domain resource allocation, a frequency domain resource allocation, a spatial domain resource allocation, etc.) of the one or more simultaneous communications, a transmit frequency associated with the one or more simultaneous communications, a receive frequency associated with the one or more simultaneous communications, a resource block separation between or among the multiple simultaneous communications, a frequency separation between or among the multiple simultaneous communications, a beam direction associated with the one or more simultaneous communications, a channel type (e.g., a physical downlink control channel (PDCCH), a physical downlink shared channel (PDSCH), a physical uplink shared channel (PUSCH), a physical uplink control channel (PUCCH), etc.) associated with the one or more simultaneous communications, an MCS associated with the one or more simultaneous communications, a rank (e.g., as an indication by a rank indication) associated with the one or more simultaneous communications, etc.

[0065]

[0071] As indicated by reference numeral 510, a child node may transmit an indication of the child node's capabilities (sometimes referred to as a capability indication) for simultaneous communication. In some aspects, the child node may transmit the capability indication to the child node's parent node or to multiple parent nodes of the child node, as shown in FIG. 5. Additionally or alternatively, the child node may transmit the capability indication to the IAB donor 405 (e.g., a CU of the IAB donor 405) via an F1 interface (e.g., an F1 application protocol (F1-AP) interface), etc. In some aspects, the child node's parent node may transmit or relay the capability indication towards or to the IAB donor 405. A child node may send capability indications periodically (e.g., according to a reporting configuration), semi-statically (e.g., in an RRC message), dynamically (e.g., in uplink control information), based at least in part on a dynamic request (e.g., in downlink control information), based at least in part on detecting a triggering event (e.g., a change in the child node's capability for simultaneous communication), etc.

[0066]

[0072] In some aspects, a child node may transmit an indication of capabilities based at least in part on receiving a reporting configuration from a control node (e.g., the child node's parent node, the IAB donor 405, etc.). The reporting configuration may request a capability indication, may indicate one or more resources for transmission of the capability indication, may indicate a periodicity for transmission of the capability indication, may indicate one or more parameters to be included in the capability indication, may indicate a combination of parent nodes, MT components, and / or TRPs for which capabilities for simultaneous communication should be reported, etc. The reporting configuration may be transmitted semi-statically (e.g., in an RRC message) and / or dynamically (e.g., in downlink control information).

[0067]

[0073] In some aspects, a child node may transmit an indication of a capability for simultaneous communication for all combinations of parent nodes with which the child node is in communication (e.g., for all combinations of parent nodes to which the child node is connected, for which an RRC connection is established, etc.). Similarly, in some aspects, a child node may transmit an indication of a capability for simultaneous communication for all combinations of MT components included in the child node. Similarly, in some aspects, a child node may transmit an indication of a capability for simultaneous communication for all combinations of TRPs included in the child node.

[0068]

[0074] Alternatively, a child node may transmit an indication of capabilities for simultaneous communication for a subset of parent nodes with which the child node is in communication, for a subset of MT components included in the child node, and / or for a subset of TRPs included in the child node. In some aspects, the subset (or each subset) may be indicated in a reporting configuration.

[0069]

[0075] In some aspects, a child node may transmit (e.g., along with the capability indication) an indication of whether the child node's capability for simultaneous communication is subject to a condition (e.g., whether the capability is conditional or unconditional). In some aspects, the indication of whether the capability for simultaneous communication is conditional or unconditional is a single bit. A first value of the bit (e.g., 0) may indicate that the capability is not subject to a condition (e.g., unconditional), and a second value of the bit (e.g., 1) may indicate that the capability is subject to a condition (e.g., conditional). In some aspects, the indication of whether the capability for simultaneous communication is conditional or unconditional includes an indication of the condition under which the simultaneous communication by the child node is subject. Exemplary conditions are described above.

[0070]

[0076] As indicated by reference numeral 515, a child node may communicate with another node in the IAB network based at least in part on the child node's capabilities for simultaneous communication. The other nodes may include control nodes that configure and / or schedule resources for the child node, such as, for example, the child node's parent node (e.g., the parent node's DU), the IAB donor 405 (e.g., the CU and / or DU of the IAB donor 405), etc. For example, the control node may send a configuration to the child node and / or schedule resources for the child node (e.g., by sending a resource allocation to the child node) based at least in part on the capabilities. In some aspects, a capability indication may be sent to and received by the CU of the IAB donor 405, which may send or relay the capability indication to or towards one or more parent nodes of the child node. Additionally or alternatively, the CU may send configuration and / or resource allocations to or towards the child node's parent node, which may send or relay the configuration and / or resource allocations to or towards the child node.

[0071]

[0077] As an example, if a child node is capable of communicating with multiple parent nodes simultaneously, the control node may schedule resources for the first parent node as well as for the second parent node. Additionally, the child node may transmit simultaneous communications in the scheduled resources. In some aspects, the child node may communicate with multiple parent nodes of the child node simultaneously using multiple MT components of the child node and / or using multiple TRPs of the child node based at least in part on capabilities, as described in further detail with respect to FIGS. 6-9.

[0072]

[0078] In some aspects, a child node may receive a configuration or resource allocation based at least in part on a capability indication and may not be capable of supporting the configuration or resource allocation. For example, simultaneous communication by a child node may be subject to a condition and the configuration or resource allocation may violate this condition (e.g., because the child node did not indicate that the simultaneous communication is subject to this condition, because the child node did not indicate this condition, or due to an error, among other examples). In this case, the child node may transmit an indication that the child node does not support the configuration or resource allocation. In some aspects, if the child node supports the configuration or resource allocation, the child node may transmit an indication that the child node supports the configuration or resource allocation. The child node may transmit an indication of whether the child node supports the configuration or resource allocation to a parent node or a control node, such as an IAB donor 405.

[0073]

[0079] As a further specific example, a child node may receive downlink control information (DCI) indicating a first set of resources scheduled for the child node (e.g., for communication with a first parent node of the child node, for communication using a first MT component of the child node, and / or for communication using a first TRP of the child node). The child node may determine that the first set of resources conflicts with a second set of resources scheduled for the child node (e.g., for communication with a second parent node of the child node, for communication using a second MT component of the child node, and / or for communication using a second TRP of the child node). For example, the first set of resources and the second set of resources may conflict due to a condition related to the ability for simultaneous communication. Based at least in part on this determination, the child node may transmit an indication (e.g., in uplink control information (UCI)) that the child node is not capable of communicating using the first set of resources.

[0074]

[0080] By enabling an IAB node to signal its capability for simultaneous communication over multiple links and then communicate simultaneously using multiple links, some techniques and apparatus described herein can reduce latency, improve throughput, improve reliability, improve spectral efficiency, etc. by utilizing the IAB node's capability for simultaneous communication. Additionally, by using the capability to configure the IAB node and / or schedule resources for the IAB node, configuration errors and / or resource scheduling conflicts may be reduced.

[0075]

[0081] As noted above, Figure 5 is provided as an example. Other examples may differ from those described with respect to Figure 5.

[0076]

[0082] FIG. 6 illustrates an example 600 of simultaneous communication capability signaling in an IAB network according to various aspects of the disclosure. The example 600 pertains to capability signaling for simultaneous communication with multiple parent nodes. As in FIG. 5, the IAB network may include an IAB donor 405 and one or more IAB nodes 410, shown as a first IAB node 410-1, which is a child node of both a second IAB node 410-2 and a third IAB node 410-3. Hereinafter, the first IAB node 410-1 is referred to as a child node, the second IAB node 410-2 is referred to as a first parent node (shown as parent node 1 or P1), and the third IAB node 410-3 is referred to as a second parent node (shown as parent node 2 or P2). Although the child nodes are shown as IAB nodes, in some aspects, the child nodes may be UEs 120.

[0077]

[0083] As indicated by reference numeral 605, a child node may determine a capability of the child node for simultaneous communication. In example 600, the capability is a capability for simultaneous communication with multiple parent nodes of the child node. For example, the capability may be the capability for the child node to communicate with multiple parent nodes of the child node simultaneously. As described above with respect to FIG. 5, the capability for simultaneous communication with multiple parent nodes may be for a single RAT, may be for multiple RATs (e.g., a first RAT for a first parent node and a second RAT for a second parent node), and / or may be subject to conditions.

[0078]

[0084] As indicated by reference numeral 610, a child node may transmit an indication of the child node's capability for simultaneous communication with multiple parent nodes, as described above with respect to FIG. 5. For example, the capability indication may indicate whether the child node supports simultaneous transmission to multiple parents of the child node, such as simultaneous transmission from the child node's MT to a first parent node and from the child node's MT to a second parent node, shown as MT-TX to P1 & MT-TX to P2. Additionally or alternatively, the capability indication may indicate whether the child node supports simultaneous reception from multiple parent nodes of the child node, such as simultaneous reception by the child node's MT from a first parent node and by the child node's MT from a second parent node, shown as P1 to MT-RX & P2 to MT-RX. Additionally or alternatively, the capability indication may indicate whether the child node supports simultaneously transmitting to the child node's first parent and receiving from the child node's second parent, such as transmitting by the child node's MT to a first parent node and receiving by the child node's MT from a second parent node simultaneously (shown as MT-TX to P1 & MT-RX to P2), or transmitting by the child node's MT to a second parent node and receiving by the child node's MT from the first parent node simultaneously (shown as MT-RX to P1 & MT-TX to P2).

[0079]

[0085] In some aspects, the capability indication may be a bitmap, where each bit corresponds to a combination of simultaneous transmissions and / or receptions for the combination of parent nodes. Alternatively, the capability indication may be an index value, where different index values ​​map to different combinations of simultaneous transmissions and / or receptions for the combination of parent nodes. In some aspects, the capability indication may identify parent nodes with which the node is able to communicate simultaneously (e.g., shown as P1 and P2, but which may include cell identifiers, node identifiers, IAB node identifiers, base station identifiers, etc.).

[0080]

[0086] In some aspects, a child node's capability for simultaneous communication may apply to two parent nodes of the child node, as shown in FIG. 6. Alternatively, a child node's capability for simultaneous communication may apply to more than two parent nodes of the child node, such as the child node's three parent nodes P1, P2, and P3 (not shown). In this case, the child node may report simultaneous combined capabilities for multiple pairs of parent nodes, such as P1 and P2 (described above and shown in FIG. 6), P1 and P3 (as above and in FIG. 6, but with P2 replaced with P3), and P2 and P3 (as above and in FIG. 6, but with P1 replaced with P3). Additionally or alternatively, a child node may indicate capability for simultaneous communication with more than two parents. For example, a child node may indicate that the child node has the capability to simultaneously transmit to a first parent node using the child node's MT, transmit to a second parent node using the child node's MT, and receive from a third parent node using the child node's MT (e.g., MT-TX to P1 & MT-TX to P2 & P3 to MT-RX).

[0081]

[0087] In some aspects, a child node may indicate capabilities for simultaneous communication for all combinations of parent nodes (e.g., all combinations of simultaneous transmit and receive capabilities for all combinations of parent nodes). For example, in the case of three parent nodes (P1, P2, and P3), a child node may indicate one or more of the following capabilities: MT-TX to P1&MT-TX to P2&MT-TX to P3, MT-TX to P1&MT-TX to P2&P3 to MT-RX, MT-TX to P1&P2 to MT-RX&MT-TX to P3, P1 to MT-RX&MT-TX to P2&MT-TX to P3, MT-TX to P1&P2 to MT-RX&P3 to MT-RX, P1 to MT-RX&P2 to MT-RX&MT-TX to P3, P1 to MT-RX&MT-TX to P2&P3 to MT-RX, and / or P1 to MT-RX&P2 to MT-RX&P3 to MT-RX. Alternatively, a child node may indicate a capability for simultaneous communication for a subset of parent nodes of three or more parent nodes. In some aspects, the subset may include only combinations of parent nodes with which the child node is capable of simultaneous communication (and not include any combinations of parent nodes with which the child node is not capable of simultaneous communication). Additionally or alternatively, the subset may be indicated and / or required in the reporting configuration.

[0082]

[0088] As indicated by reference numeral 615, a child node may communicate with another node (e.g., a parent node or a control node such as a CU) in the IAB network based at least in part on the child node's capability for simultaneous communication, as described above with respect to FIG. 5. For example, the control node may send a configuration to the child node and / or schedule resources for the child node (e.g., by sending a resource allocation to the child node) based at least in part on the capability. As an example, if a child node is capable of communicating with multiple parent nodes simultaneously, the control node may schedule resources (e.g., time resources, frequency resources, or space resources, among other examples) for a first parent node that are also scheduled for a second parent node. Furthermore, the child node may transmit simultaneous communications in the scheduled resources. For example, a child node may communicate with multiple parent nodes of the child node simultaneously.

[0083]

[0089] By enabling an IAB node to signal its capability for simultaneous communication with multiple parent nodes and then communicate with multiple parent nodes simultaneously, some techniques and apparatus described herein can reduce latency, improve throughput, improve reliability, improve spectral efficiency, etc. by utilizing the IAB node's capability for simultaneous communication. Additionally, by using the capability to configure the IAB node and / or schedule resources for the IAB node, configuration errors and / or resource scheduling conflicts may be reduced.

[0084]

[0090] As noted above, Figure 6 is provided as an example. Other examples may differ from those described with respect to Figure 6.

[0085]

[0091] FIG. 7 illustrates an example 700 of simultaneous communication capability signaling in an IAB network according to various aspects of the disclosure. The example 700 pertains to capability signaling for simultaneous communication using multiple MT components (e.g., multiple MTs or multiple MT functions) of a child node. As in FIG. 5, the IAB network may include an IAB donor 405 and one or more IAB nodes 410, shown as a first IAB node 410-1, which is a child node of both a second IAB node 410-2 and a third IAB node 410-3. Hereinafter, the first IAB node 410-1 is referred to as a child node, the second IAB node 410-2 is referred to as a first parent node (shown as parent node 1 or P1), and the third IAB node 410-3 is referred to as a second parent node (shown as parent node 2 or P2). Although the child nodes are shown as IAB nodes, in some aspects, the child nodes may be UEs 120.

[0086]

[0092] 7, a child node may include multiple MT components, shown as a first MT component MT1 and a second MT component MT2. As shown, the first MT component may be used to communicate with a first parent node, and the second MT component may be used to communicate with a second parent node. Thus, different MT components of a child node may communicate with different parent nodes of the child node.

[0087]

[0093] As indicated by reference numeral 705, a child node may determine a capability of the child node for simultaneous communication. In example 700, the capability is a capability for simultaneous communication for multiple MT components of the child node. For example, the capability may be an ability for the child node to communicate simultaneously using multiple MT components of the child node. As described above with respect to FIG. 5, the capability for simultaneous communication using multiple MT components may be for a single RAT, may be for multiple RATs (e.g., a first RAT for a first MT component and a second RAT for a second MT component), and / or may be subject to conditions.

[0088]

[0094] As indicated by reference numeral 710, a child node may transmit an indication of the child node's capability for simultaneous communication using multiple MT components, as described above with respect to FIG. 5. For example, the capability indication may indicate whether the child node supports simultaneous transmission by multiple MT components of the child node, such as simultaneous transmission by a first MT component of the child node and by a second MT component of the child node, shown as MT1-TX&MT2-TX. Additionally or alternatively, the capability indication may indicate whether the child node supports simultaneous reception by multiple MT components of the child node, such as simultaneous reception by a first MT component of the child node and by a second MT component of the child node, shown as MT1-RX&MT2-RX. Additionally or alternatively, the capability indication may indicate whether the child node supports transmission by a first MT component of the child node and reception by a second MT component of the child node simultaneously, such as transmission by a first MT component of the child node and reception by a second MT component of the child node simultaneously (shown as MT1-TX & MT2-RX), or transmission by a second MT component of the child node and reception by the first MT component of the child node simultaneously (shown as MT1-RX & MT2-TX).

[0089]

[0095] In some aspects, the capability indication may be a bitmap, where each bit corresponds to a combination of simultaneous transmission and / or reception for a combination of MT components. Alternatively, the capability indication may be an index value, where different index values ​​map to different combinations of simultaneous transmission and / or reception for a combination of MT components. In some aspects, the capability indication may identify MT components (e.g., shown as MT1 and MT2, but which may include cell identifiers, node identifiers, IAB node identifiers, base station identifiers, etc.) that a node may use to communicate with simultaneously.

[0090]

[0096] In some aspects, a child node's capability for simultaneous communication may apply to two MT components of the child node, as shown in FIG. 7. Alternatively, a child node's capability for simultaneous communication may apply to three or more MT components of the child node. In this case, the child node may report simultaneous combined capabilities for multiple pairs of MT components, such as MT1 and MT2 (described above and shown in FIG. 7), MT1 and MT3 (as above and in FIG. 7, but replacing MT2 with MT3), and MT2 and MT3 (as above and in FIG. 7, but replacing MT1 with MT3). Additionally or alternatively, the child node may indicate a capability for simultaneous communication using three or more MT components. For example, the child node may indicate that the child node has the capability to simultaneously transmit using a first MT component of the child node, transmit using a second MT component of the child node, and receive using a third MT component of the child node (e.g., MT1-TX&MT2-TX&MT3-RX).

[0091]

[0097] In some aspects, a child node may indicate capabilities for simultaneous communication for all combinations of MT components (e.g., all combinations of simultaneous transmit and receive capabilities for all combinations of MT components). For example, in the case of three MT components (MT1, MT2, and MT3), a child node may indicate one or more of the following capabilities: MT1-TX&MT2-TX&MT3-TX, MT1-TX&MT2-TX&MT3-RX, MT1-TX&MT2-RX&MT3-TX, MT1-RX&MT2-TX&MT3-TX, MT1-TX&MT2-RX&MT3-RX, MT1-RX&MT2-RX&MT3-TX, MT1-RX&MT2-TX&MT3-RX, and / or MT1-RX&MT2-RX&MT3-RX. Alternatively, a child node may indicate capabilities for simultaneous communication for a subset of MT components of three or more MT components. In some aspects, the subset may be a subset that includes only combinations of MT components with which the child node is capable of communicating simultaneously (and does not include any combinations of MT components with which the child node is not capable of communicating simultaneously). Additionally or alternatively, the subset may be indicated and / or required in the reporting configuration.

[0092]

[0098] As indicated by reference numeral 715, a child node may communicate with another node in the IAB network (e.g., a parent node or a control node such as a CU) based at least in part on the child node's capability for simultaneous communication, as described above with respect to FIG. 5. For example, the control node may send a configuration to the child node and / or schedule resources for the child node (e.g., by sending a resource allocation to the child node) based at least in part on the capability. As an example, if a child node is capable of communicating using multiple MT components simultaneously, the control node may schedule resources (e.g., time resources, frequency resources, or space resources, among other examples) for a first MT component of the child node that are also scheduled for a second MT component of the child node. Furthermore, the child node may transmit simultaneous communications in the scheduled resources. For example, a child node may communicate simultaneously using multiple MT components of the child node.

[0093]

[0099] By enabling an IAB node to signal its capability for simultaneous communication with multiple MT components and then communicate simultaneously using multiple MT components, some techniques and apparatus described herein can reduce latency, improve throughput, improve reliability, improve spectral efficiency, etc. by utilizing the IAB node's capability for simultaneous communication. Additionally, by using the capability to configure the IAB node and / or schedule resources for the IAB node, configuration errors and / or resource scheduling conflicts may be reduced.

[0094]

[0100] As noted above, Figure 7 is provided as an example. Other examples may differ from those described with respect to Figure 7.

[0095]

[0101] FIG. 8 illustrates an example 800 of simultaneous communication capability signaling in an IAB network according to various aspects of the disclosure. The example 800 pertains to capability signaling for simultaneous communication using multiple TRPs (or multiple panels) of a child node. As in FIG. 5, the IAB network may include an IAB donor 405 and one or more IAB nodes 410, shown as a first IAB node 410-1, which is a child node of both a second IAB node 410-2 and a third IAB node 410-3. Hereinafter, the first IAB node 410-1 is referred to as a child node, the second IAB node 410-2 is referred to as a first parent node (shown as parent node 1 or P1), and the third IAB node 410-3 is referred to as a second parent node (shown as parent node 2 or P2). Although the child nodes are shown as IAB nodes, in some aspects, the child nodes may be UEs 120.

[0096]

[0102] As shown in FIG. 8, the MT component of the child node may include multiple TRPs, shown as a first TRP of the MT component (e.g., MT-TRP1) and a second TRP of the MT component (e.g., MT-TRP2). Additionally or alternatively, the DU component of the child node may include multiple TRPs, shown as a first TRP of the DU component (e.g., DU-TRP1) and a second TRP of the DU component (e.g., DU-TRP2). In some aspects, the first MT-TRP may be used to communicate with a first parent node and the second MT-TRP may be used to communicate with a second parent node. Thus, different MT-TRPs of the child node may communicate with different parent nodes of the child node. Additionally or alternatively, the first DU-TRP may be used to communicate with a first child node and the second DU-TRP may be used to communicate with a second child node. Thus, different DU-TRPs of the child node may communicate with different child nodes for a child node.

[0097]

[0103] As indicated by reference numeral 805, a child node may determine a capability of the child node for simultaneous communication. In example 800, the capability is a capability for simultaneous communication on multiple TRPs of the child node. For example, the capability may be a capability for the child node to communicate simultaneously using multiple TRPs of the child node. As described above with respect to FIG. 5, the capability for simultaneous communication using multiple TRPs may be for a single RAT, may be for multiple RATs (e.g., a first RAT for a first MT component and a second RAT for a second MT component), and / or may be subject to conditions.

[0098]

[0104] As indicated by reference numeral 810, the child node may transmit an indication of the child node's capability for simultaneous communication using multiple TRPs, as described above with respect to FIG. 5. For example, the capability indication may indicate whether the child node supports simultaneous transmission by multiple TRPs of the child node, such as simultaneous transmission by a first TRP of the child node and by a second TRP of the child node. Additionally or alternatively, the capability indication may indicate whether the child node supports simultaneous reception by multiple TRPs of the child node, such as simultaneous reception by a first TRP of the child node and by a second TRP of the child node. Additionally or alternatively, the capability indication may indicate whether the child node supports transmission by a first TRP of the child node and simultaneous reception by a second TRP of the child node, such as reception by a second TRP of the child node and simultaneous transmission by a first TRP of the child node, or reception by a second TRP of the child node and simultaneous reception by a first TRP of the child node.

[0099]

[0105] Additionally or alternatively, the capability indication may indicate whether the child node supports simultaneous communication by the TRP of the MT component of the child node and the TRP of the DU of the child node, shown as MT-TX&DU-TRP1-TX (e.g., for simultaneous transmission). Additionally or alternatively, the capability indication may indicate whether the child node supports simultaneous communication by the DU of the child node and the TRP of the MT component of the child node, shown as MT-TRP1-TX&DU-TX (e.g., for simultaneous transmission). Additionally or alternatively, the capability indication may indicate whether the child node supports simultaneous communication by the TRP of the DU of the child node and the TRP of the MT component of the child node, shown as MT-TRP1-TX&DU-TRP1-TX (e.g., for simultaneous transmission). Additionally or alternatively, the capability indication may indicate whether the child node supports simultaneous communication by a first TRP of the MT component of the child node and a second TRP of the MT component of the child node, shown as MT-TRP1-TX & MT-TRP2-TX (e.g., for simultaneous transmission). Additionally or alternatively, the capability indication may indicate whether the child node supports simultaneous communication by a first TRP of the DU of the child node and a second TRP of the DU of the child node, shown as DU-TRP1-TX & DU-TRP2-TX (e.g., for simultaneous transmission). Although these examples show an indication of support for simultaneous transmission, in a similar manner, the child node may indicate support for simultaneous reception, or support for simultaneous transmission and reception.

[0100]

[0106] In some aspects, the capability indication may be a bitmap, where each bit corresponds to a combination of simultaneous transmission and / or reception for the combination of TRPs. Alternatively, the capability indication may be an index value, where different index values ​​map to different combinations of simultaneous transmission and / or reception for the combination of TRPs. In some aspects, the capability indication may identify TRPs (e.g., shown as MT-TRP1, MT-TRP2, DU-TRP1, and DU-TRP2, but may include cell identifiers, node identifiers, IAB node identifiers, base station identifiers, TRP identifiers, etc.) that the node may use to communicate with simultaneously.

[0101]

[0107] In some aspects, the child node's capability for simultaneous communication may apply to two TRPs of the child node (e.g., per MT or per DU) as shown in FIG. 8. Alternatively, the child node's capability for simultaneous communication may apply to three or more TRPs of the child node (e.g., per MT or per DU). In this case, the child node may report simultaneous combined capabilities for multiple pairs of TRPs, such as MT-TRP1 and MT-TRP2, MT-TRP1 and MT-TRP3, and MT-TRP2 and MT-TRP3. Additionally or alternatively, the child node may indicate capability for simultaneous communication using three or more TRPs. For example, the child node may indicate that the child node has the capability to simultaneously transmit using the child node's first TRP, transmit using the child node's second TRP, and receive using the child node's third TRP (e.g., MT-TRP1-TX&MT-TRP2-TX&MT-TRP3-RX).

[0102]

[0108] In some aspects, a child node may indicate capabilities for simultaneous communication for all combinations of TRPs (eg, all combinations of simultaneous transmit and receive capabilities for all combinations of TRPs). For example, for three TRPs of an MT component (MT-TRP1, MT-TRP2, and MT-TRP3), a child node may indicate one or more of the following capabilities: MT-TRP1-TX&MT-TRP2-TX&MT-TRP3-TX, MT-TRP1-TX&MT-TRP2-TX&MT-TRP3-RX, MT-TRP1-TX&MT-TRP2-RX&MT-TRP3-TX, MT-TRP1-RX&MT-TRP2-TX&MT-TRP3-TX, MT-TRP1-TX&MT-TRP2-RX&MT-TRP3-RX, MT-TRP1-RX&MT-TRP2-RX&MT-TRP3-TX, MT-TRP1-RX&MT-TRP2-TX&MT-TRP3-RX, and / or MT-TRP1-RX&MT-TRP2-RX&MT-TRP3-RX. Alternatively, a child node may indicate a capability for simultaneous communication for a subset of the three or more TRPs. In some aspects, the subset may include only combinations of TRPs with which the child node is capable of simultaneous communication (and not include any combinations of TRPs with which the child node is not capable of simultaneous communication). Additionally or alternatively, the subset may be indicated and / or requested in the reporting configuration.

[0103]

[0109] As indicated by reference numeral 815, a child node may communicate with another node (e.g., a parent node or a control node such as a CU) in the IAB network based at least in part on the child node's capability for simultaneous communication, as described above with respect to FIG. 5. For example, the control node may send a configuration to the child node and / or schedule resources for the child node (e.g., by sending a resource allocation to the child node) based at least in part on the capability. As an example, if a child node is capable of communicating using multiple TRPs at the same time, the control node may schedule resources (e.g., time resources, frequency resources, or space resources, among other examples) for a first TRP of the child node, as well as for a second TRP of the child node. Furthermore, the child node may transmit simultaneous communication in the scheduled resources. For example, a child node may communicate simultaneously using multiple TRPs of the child node.

[0104]

[0110] By enabling an IAB node to signal its capability for simultaneous communication with multiple TRPs and then communicate simultaneously using multiple TRPs, some techniques and apparatus described herein can reduce latency, improve throughput, improve reliability, improve spectral efficiency, etc. by utilizing the IAB node's capability for simultaneous communication. Additionally, by using the capability to configure the IAB node and / or schedule resources for the IAB node, configuration errors and / or resource scheduling conflicts may be reduced.

[0105]

[0111] As described above with respect to Figure 5, in some aspects a child node may indicate a capability for simultaneous communication with multiple parent nodes of the child node, using multiple MT components of the child node, and / or using multiple TRPs of the child node. Thus, two or more techniques described in Figures 6, 7, and 8 may be combined to indicate a combination of capabilities, such as a capability for simultaneous communication with multiple parents and using multiple MT components, a capability for simultaneous communication with multiple parents and using multiple TRPs, a capability for simultaneous communication using multiple MT components and using multiple TRPs (e.g., where each MT component may include one or more TRPs), or a capability for simultaneous communication with multiple parents, using multiple MT components, and using multiple TRPs.

[0106]

[0112] As noted above, Figure 8 is provided as an example. Other examples may differ from those described with respect to Figure 8.

[0107]

[0113] FIG. 9 illustrates an example 900 of simultaneous communication capability signaling in an IAB network according to various aspects of the disclosure. The example 900 pertains to capability signaling for simultaneous communication using multiple cells of a child node, multiple TRPs of a child node (or multiple panels of a child node), etc. As in FIG. 5, the IAB network may include an IAB donor 405 and one or more IAB nodes 410, shown as a first IAB node 410-1, which is a child node of both a second IAB node 410-2 and a third IAB node 410-3. Hereinafter, the first IAB node 410-1 is referred to as a child node, the second IAB node 410-2 is referred to as a first parent node (shown as parent node 1 or P1), and the third IAB node 410-3 is referred to as a second parent node (shown as parent node 2 or P2). Although the child nodes are shown as IAB nodes, in some aspects, the child nodes may be UEs 120.

[0108]

[0114] As shown in FIG. 9, a DU component of a child node may be capable of communicating using multiple cells, shown as a first cell (e.g., cell 1 or DU-cell 1) and a second cell (e.g., cell 2 or DU-cell 2). In some aspects, the first cell may be used to communicate with a first child node, and the second cell may be used to communicate with a second child node. Alternatively, the first cell and the second cell may both be used to communicate with a single child node (e.g., using different component carriers). Thus, different cells of a child node may communicate with different child nodes for a child node, or with the same child node for a child node.

[0109]

[0115] Additionally or alternatively, a DU component of a child node may include multiple TRPs, shown as a first TRP of the DU component (e.g., first DU-TRP, TRP1, or DU-TRP1) and a second TRP of the DU component (e.g., second DU-TRP, TRP2, or DU-TRP2). In some aspects, the first DU-TRP may be used to communicate with a first child node and the second DU-TRP may be used to communicate with a second child node. Alternatively, both the first DU-TRP and the second DU-TRP may be used to communicate with a single child node (e.g., using multiple MIMO layers). Thus, different DU-TRPs of a child node may communicate with different child nodes for a child node or with the same child node for a child node.

[0110]

[0116] As indicated by reference numeral 905, the child node may determine the capability of the child node for simultaneous communication. In example 900, the capability is the capability for simultaneous communication for multiple cells and / or multiple TRPs of the child node. For example, the capability may be the capability of the child node to simultaneously communicate using multiple cells of the child node and a single DU, the capability of the child node to simultaneously communicate using a single cell of the child node and multiple TRPs, the capability of the child node to simultaneously communicate using multiple cells of the child node and multiple TRPs (e.g., with one TRP per cell, as shown), etc. The capability for simultaneous communication using multiple cells and / or multiple TRPs may be for a single RAT, may be for multiple RATs (e.g., a first RAT for a first cell and / or first TRP, a second RAT for a second cell and / or second TRP, etc.), and / or may be subject to conditions, as described elsewhere herein.

[0111]

[0117] As indicated by reference numeral 910, the child node may transmit an indication of the child node's capability for simultaneous communication using multiple cells and / or multiple TRPs, as described above with respect to FIG. 5. For example, the capability indication may indicate whether the child node supports simultaneous communication using multiple cells of the child node DU, shown as DU-cell1 & DU-cell2. Additionally or alternatively, the capability indication may indicate whether the child node supports simultaneous communication using multiple TRPs for a single cell of the child node DU, shown as DU-TRP1-cell1 & DU-TRP2-cell1. Additionally or alternatively, the capability indication may indicate whether the child node supports simultaneous communication using multiple TRPs for multiple cells of the child node DU, shown as DU-TRP1-cell1 & DU-TRP2-cell2.

[0112]

[0118] In the example described with reference to reference numeral 910, the capability indication for simultaneous communication is for both simultaneous transmission and simultaneous reception. In some aspects, the child node may specifically indicate whether the capability indication is for simultaneous transmission, simultaneous reception, or both. For example, the capability indication may indicate whether the child node supports simultaneous transmission using multiple cells of the child node DU (e.g., DU-cell1-TX&DU-cell2-TX), may indicate whether the child node supports simultaneous reception using multiple cells of the child node DU (e.g., DU-cell1-RX&DU-cell2-RX), or may indicate whether the child node supports simultaneous transmission and reception using multiple cells of the child node DU (e.g., DU-cell1&DU-cell2 as shown). Additionally or alternatively, the capability indication may indicate whether the child node supports simultaneous transmission using multiple TRPs for a single cell of the child node DU (e.g., DU-TRP1-Cell1-TX & DU-TRP2-Cell1-TX), may indicate whether the child node supports simultaneous reception using multiple TRPs for a single cell of the child node DU (e.g., DU-TRP1-Cell1-RX & DU-TRP2-Cell1-RX), or may indicate whether the child node supports simultaneous transmission and reception using multiple TRPs for a single cell of the child node DU (e.g., DU-TRP1-Cell1 & DU-TRP2-Cell1 as shown). Additionally or alternatively, the capability indication may indicate whether the child node supports simultaneous transmission using multiple TRPs for multiple cells of the child node DU (e.g., DU-TRP1-Cell 1-TX & DU-TRP2-Cell 2-TX), whether the child node supports simultaneous reception using multiple TRPs for multiple cells of the child node DU (e.g., DU-TRP1-Cell 1-RX & DU-TRP2-Cell 2-RX), or whether the child node supports simultaneous communication using multiple TRPs for multiple cells of the child node DU (e.g., DU-TRP1-Cell 1 & DU-TRP2-Cell 2 as shown).

[0113]

[0119] In some aspects, a control node may use a default capability (e.g., unsignaled capability) of a child node for configuring the child node, scheduling the child node, etc. The default capability may be that the child node supports simultaneous transmission and reception on different cells. For example, the default capability may be that the child node supports simultaneous transmission on a first cell and a second cell, and that the child node supports simultaneous reception on the first cell and a second cell. In some aspects, the control node may use the default capability unless the child node explicitly provides a capability indication indicating a capability of the child node that differs from the default capability.

[0114]

[0120] In some aspects, the child node may report only pairs or sets of cells for which simultaneous communication is not supported, and the control node may use default capabilities for other pairs or sets of cells. For example, for a child node supporting three cells, the child node may indicate that the child node is not capable of simultaneous communication using the first cell and the second cell. In this case, the control node may determine that the child node is capable of simultaneous communication using the first cell and the third cell, and the control may also be capable of simultaneous communication using the second cell and the third cell. In some aspects, the child node may indicate conditions associated with simultaneous communication, such as TDM requirements or conditions, indicating that a set or pair of cells and / or a set or pair of TRPs cannot operate simultaneously.

[0115]

[0121] In some aspects, the capability indication may be a bitmap, where each bit corresponds to a combination of simultaneous transmission and / or reception for a combination of cells and / or TRPs. Alternatively, the capability indication may be an index value, where different index values ​​map to different combinations of simultaneous transmission and / or reception for a combination of cells and / or TRPs. In some aspects, the capability indication may identify cells that the node is able to use to communicate with simultaneously.

[0116]

[0122] In some aspects, a child node's capability for simultaneous communication may apply to two cells of the child node, as shown in FIG. 9. Alternatively, a child node's capability for simultaneous communication may apply to three or more cells of the child node. In this case, the child node may report simultaneous combining capabilities for multiple pairs of cells. Additionally or alternatively, the child node may indicate a capability for simultaneous communication using three or more cells. For example, the child node may indicate that the child node has the capability to simultaneously transmit using a first cell of the child node, transmit using a second cell of the child node, and receive using a third cell of the child node.

[0117]

[0123] In some aspects, a child node may indicate a capability for simultaneous communication for all combinations of cells (e.g., all combinations of simultaneous transmit and receive capabilities for all combinations of cells). Alternatively, a child node may indicate a capability for simultaneous communication for a subset of cells of the three or more cells. In some aspects, the subset may be a subset that includes only combinations of cells with which the child node is capable of communicating simultaneously (and does not include any combinations of TRPs with which the child node is not capable of communicating simultaneously). Alternatively, the subset may be a subset that includes only combinations of cells with which the child node is not capable of communicating simultaneously (and does not include any combinations of TRPs with which the child node is capable of communicating simultaneously). Additionally or alternatively, the subset may be indicated and / or requested in the reporting configuration.

[0118]

[0124] As indicated by reference numeral 915, a child node may communicate with another node (e.g., a parent node or a control node such as a CU) in the IAB network based at least in part on the child node's capability for simultaneous communication, as described above with respect to FIG. 5. For example, the control node may send a configuration to the child node and / or schedule resources for the child node (e.g., by sending a resource allocation to the child node) based at least in part on the capability. As an example, if a child node is capable of communicating using multiple cells simultaneously, the control node may schedule resources (e.g., time resources, frequency resources, or space resources, among other examples) for a first cell of the child node, as well as for a second cell of the child node. Furthermore, the child node may transmit simultaneous communication in the scheduled resources. For example, a child node may communicate simultaneously using multiple cells of the child node (e.g., may communicate with one or more child nodes for the child node).

[0119]

[0125] By enabling an IAB node to signal its capability for simultaneous communication with multiple cells and then communicate simultaneously using multiple cells, some techniques and apparatus described herein can reduce latency, improve throughput, improve reliability, improve spectral efficiency, etc. by utilizing the IAB node's capability for simultaneous communication. Additionally, by using the capability to configure the IAB node and / or schedule resources for the IAB node, configuration errors and / or resource scheduling conflicts may be reduced.

[0120]

[0126] In some aspects, a child node may indicate a capability for simultaneous communication with multiple parent nodes of the child node, with multiple child nodes for the child node, using multiple MT components of the child node, using multiple TRPs of the child node, and / or using multiple cells of the child node. Thus, two or more techniques described in Figures 6, 7, 8, and 9 may be combined to indicate a combination of capabilities, such as a capability for simultaneous communication with multiple parents and using multiple MT components, a capability for simultaneous communication with multiple parents and / or children and using multiple TRPs, a capability for simultaneous communication using multiple MT components and using multiple TRPs (e.g., where each MT component may include one or more TRPs), a capability for simultaneous communication using multiple cells, using multiple TRPs, or a capability for simultaneous communication with multiple parents, using multiple MT components, and using multiple TRPs, among other examples.

[0121]

[0127] As noted above, Figure 9 is provided as an example. Other examples may differ from those described with respect to Figure 9.
