Technical Field

[0003] 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 Art

[0004] Wireless communication systems are widely deployed to provide a variety of telecommunication services, such as telephony, video, data, messaging, and broadcasting. Typical wireless communication systems may employ multiple access technologies that can support communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single carrier frequency division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and long term evolution (LTE). LTE / LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP).

[0005] A wireless communication network may include multiple base stations (BS) that can support communications for multiple user equipments (UEs). User equipments (UEs) may communicate with base stations (BSs) via downlinks and uplinks. Downlinks (or forward links) refer to the communication link from a BS to a UE, while uplinks (or reverse links) refer to the communication link from a UE to a BS. As will be described in more detail herein, a BS may be referred to as a Node B, gNB, access point (AP), radio head, transmit receive point (TRP), new radio (NR) BS, 5G Node B, etc.

[0006] The above-mentioned multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different user equipment to communicate at municipal, national, regional and even global levels. The new radio (NR), which can also be referred to as 5G, is an enhancement set 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 spectrum efficiency, reducing costs, improving services, utilizing new spectrum, and using orthogonal frequency division multiplexing (OFDM) (CP-OFDM) with cyclic prefix (CP) on the downlink (DL), using CP-OFDM and / or SC-FDM (e.g., also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink (UL) Better integration, and support beamforming, multiple input multiple output (MIMO) antenna technology and carrier aggregation. However, as the demand for mobile broadband access continues to grow, further improvements in LTE and NR technologies are needed. Preferably, these improvements should be applicable to other multiple access technologies and telecommunication standards that adopt these technologies. Summary of the invention

[0026] The various aspects of the present disclosure are described more fully below with reference to the accompanying drawings. However, the present disclosure can be embodied in many different forms and should not be interpreted as being limited to any specific structure or function presented throughout the present disclosure. On the contrary, these aspects are provided so that the present disclosure will be comprehensive and complete, and the scope of the present disclosure will be fully conveyed to those skilled in the art. Based on the teachings herein, it should be understood by those skilled in the art that the scope of the present disclosure is intended to cover any aspect of the present disclosure disclosed herein, whether they are implemented independently of any other aspect of the present disclosure or combined with any other aspect of the present disclosure to be implemented. For example, any number of aspects set forth herein can be used to implement a device or practice method. In addition, the scope of the present disclosure is intended to cover such a device or method, that is, the device or method is practiced using other structures, functions, or structures and functions other than the various aspects of the present disclosure set forth herein or different from the various aspects of the present disclosure set forth herein. It should be understood that any aspect of the present disclosure disclosed herein can be embodied by one or more elements of the claims.

[0027] Several aspects of telecommunication systems will now be presented with reference to various devices and techniques. These devices and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms and / or the like (collectively referred to as "elements"). These elements may be implemented using hardware, software, or a combination thereof. Whether these elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0028] It should be noted that although various aspects may be described herein using terms generally associated with 3G and / or 4G wireless technologies, various aspects of the present disclosure may be applied to other generation-based communication systems (such as 5G and subsequent versions, including NR technology).

[0029] Figure 1 1 is a diagram illustrating a wireless network 100 in which various aspects of the present disclosure may be implemented. 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 a plurality of 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 a 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" may refer to a coverage area of ​​a BS and / or a BS subsystem serving the coverage area, depending on the context in which the term is used.

[0030] A BS may provide communication coverage for macro cells, pico cells, femto cells, and / or other types of cells. A macro cell may cover a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access to UEs with service subscriptions. A pico cell may cover a relatively small geographic area and may allow unrestricted access to UEs with service subscriptions. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access to UEs associated 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. In Figure 1 In the example shown, BS 110a may be a macro BS for macro cell 102a, BS 110b may be a pico BS for pico cell 102b, and BS 110c may be a femto BS for femto cell 102c. A BS may support one or more (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.

[0031] In some aspects, a cell may not necessarily be fixed, and the geographic area of ​​the cell may move according to the location of the mobile BS. In some aspects, the BSs may be interconnected with each other and / or with one or more other BSs or network nodes (not shown) in the wireless network 100 through various types of backhaul interfaces (such as direct physical connections, virtual networks, etc.) using any suitable transmission network.

[0032] The wireless network 100 may also include a relay station. A relay station is an entity that can receive transmissions of data from an upstream station (e.g., a BS or a UE) and transmit transmissions of data to a downstream station (e.g., a UE or a BS). A relay station may also be a UE that can relay transmissions for other UEs. Figure 1 In the example shown, relay BS 110d may communicate with macro BS 110a and UE 120d to facilitate communication between BS 110a and UE 120d. A relay BS may also be referred to as a relay station, relay base station, relay, or the like.

[0033] The wireless network 100 may be a heterogeneous network including different types of BSs, such as 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 effects on interference in the wireless network 100. For example, a macro BS may have a higher transmit power level (e.g., 5 watts to 40 watts), while a pico BS, a femto BS, and a relay BS may have a lower transmit power level (e.g., 0.1 watt to 2 watts).

[0034] A network controller 130 may be coupled to a set of BSs and may 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 wired backhaul.

[0035] UE 120 (e.g., 120a, 120b, 120c) may be dispersed throughout the wireless network 100, and each UE may be fixed or mobile. UE may also be referred to as an access terminal, terminal, mobile station, subscriber unit, station, etc. UE may be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device or instrument, a biosensor / 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 satellite radio, etc.), a vehicle component or sensor, a smart meter / sensor, an industrial manufacturing device, a global positioning system device, or any other suitable device configured to communicate via a wireless or wired medium.

[0036] Some UEs may 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, location tags, etc. that can communicate with a base station, another device (e.g., a remote device), or some other entity. A wireless node may provide, for example, a connection 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 Internet of Things (IoT) devices, and / or may be implemented as NB-IoT (narrowband Internet of Things) devices. Some UEs may be considered customer premises equipment (CPE). UE 120 may be included inside a housing that houses components of UE 120 (such as a processor component, a memory component, etc.).

[0037] Typically, any number of wireless networks can be deployed in a given geographic area. Each wireless network can support a specific radio access technology (RAT) and can operate on one or more frequencies. RAT can also be referred to as radio technology, air interface, etc. Frequency can also be referred to as carrier, frequency channel, etc. Each frequency can 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 can be deployed.

[0038] In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly (e.g., without using base station 110 as an intermediary to communicate with each other) using one or more sidelink channels. For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, etc.), mesh networks, etc. In this case, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by base station 110.

[0039] As pointed out above, Figure 1 is provided as an example. Other examples may be related to Figure 1 Different than described.

[0040] Figure 2 A block diagram 200 is shown showing a design of a base station 110 and a UE 120, which may be Figure 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.

[0041] At the base station 110, the transmit processor 220 may receive data for one or more UEs from the data source 212, 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) data for each UE based at least in part on the (one or more) MCS selected for the 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, upper 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)). If applicable, 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, and can provide T output symbol streams to T modulators (MOD) 232a to 232t. Each modulator 232 can process a corresponding output symbol stream (e.g., for OFDM, etc.) to obtain an output sample stream. Each modulator 232 can further 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. According to various aspects described in more detail below, position coding can be used to generate synchronization signals to convey additional information.

[0042] At UE 120, antennas 252a to 252r may receive downlink signals from base station 110 and / or other base stations, and may provide received signals to demodulators (DEMODs) 254a to 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 to 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 UE 120 to a data sink 260, and provide decoded control information and system information to a controller / processor 280. The channel processor may determine reference signal received power (RSRP), received signal strength indicator (RSSI), reference signal received quality (RSRQ), channel quality indicator (CQI), etc. In some aspects, one or more components of UE 120 may be included in a housing.

[0043] 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 including RSRP, RSSI, RSRQ, CQI, etc.) from a 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 through 254r (e.g., for DFT-s-OFDM, CP-OFDM, etc.), and transmitted to the base station 110.

[0044] At the base station 110, uplink signals from the UE 120 and other UEs may be received by the antenna 234, processed by the demodulator 232, detected by the MIMO detector 236 (if applicable), and further processed by the receive processor 238 to obtain decoded data and control information sent by the user equipment 120. The receive processor 238 may provide the decoded data to the data sink 239 and the decoded control information to the controller / processor 240. The base station 110 may include a communication unit 244 and communicate with 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.

[0045] The controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2Any other (multiple) components of may perform one or more techniques associated with 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 perform one or more techniques associated with simultaneous communication capability signaling in an IAB network. As described in more detail elsewhere herein, such a node may include a mobile terminal 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 the techniques described herein (e.g., with Figures 1 to 3 ) and / or may include one or more functions of the UE 120 described herein (e.g., with Figure 2 The DU component may perform one or more components of the UE 120 described herein (e.g., in conjunction with Figures 1 to 3 One or more functions of the base station 110 described herein (e.g., in conjunction with) such as scheduling, and / or may include the following: Figure 2 The CU component may perform one or more components of the base station 110 described herein (e.g., in conjunction with Figures 1 to 3 One or more functions of the base station 110 described herein (e.g., in conjunction with) such as configuration for other nodes, and / or may include the present invention (e.g., in conjunction with Figure 2 One or more components of the base station 110 described in combination).

[0046] In some aspects, Figure 2 The controller / processor 240 and / or node of the base station 110, the controller / processor 280 and / or node of the UE 120, and / or any other component(s) may execute or direct, for example Fig.10 Processing 1000, Fig.11 1100 and / or other processes as described herein. Memories 242 and 282 may store data and program codes for 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 for wireless communication. For example, when executed by one or more processors of base station 110 and / or UE 120, the one or more instructions may execute or direct, for example, Fig.10 Processing 1000, Fig.11 The operations of process 1100 and / or other processes as described herein. Scheduler 246 may schedule UEs for data transmission on the downlink and / or uplink.

[0047] In some aspects, a node may include: a component for sending an indication of the node's ability to communicate simultaneously relative to at least one of: multiple parent nodes of the node, multiple mobile terminal components of the node, multiple transmit-receive points of the node, multiple cells of the node, or a combination thereof; a component for communicating with another node in a wireless network based at least in part on the ability, etc. In some aspects, such components may include Figure 2 One or more components of the UE 120 and / or base station 110 (which may be included in a node) are described in conjunction.

[0048] In some aspects, the control node may include: a component for receiving an indication of a node's capability for simultaneous communication in a wireless network relative to at least one of: multiple parent nodes of the node, multiple mobile terminal components of the node, multiple transmit / receive points of the node, multiple cells of the node, or a combination thereof; a component for communicating with the node based at least in part on the capability, etc. In some aspects, such a component may include a Figure 2 One or more components of the UE 120 and / or base station 110 (which may be included in a control node) are described in conjunction.

[0049] As indicated above, Figure 2 are provided as examples. Other examples may differ from those described in Figure 2 An example of description.

[0050] Figure 3 is a diagram illustrating an example 300 of a radio access network in accordance with various aspects of the present disclosure.

[0051] As shown by reference numeral 305, a conventional (e.g., 3G, 4G, LTE, etc.) radio access network may include multiple base stations 310 (e.g., access nodes (ANs)), each of which communicates with a core network via a wired backhaul link 315 such as a fiber optic connection. The base stations 310 may communicate with UEs 320 via access links 325, which may be wireless links. In some aspects, Figure 3 The base station 310 shown may be Figure 1 The base station 110 is shown. In some aspects, Figure 3 The UE 320 shown may be Figure 1 UE 120 is shown.

[0052] As shown in the reference numeral 330, the radio access network may include a wireless backhaul network, sometimes referred to as an IAB network. In the IAB network, at least one base station is an anchor base station 335 that 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). The non-anchor base station 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 traffic. The backhaul link 350 may be a wireless link. The (multiple) anchor base stations 335 and / or the (multiple) non-anchor base stations 345 may communicate with one or more UEs 355 via an access circuit 360, which may be a wireless link for carrying access traffic. In some aspects, Figure 3 The anchor base station 335 and / or the non-anchor base station 345 shown may be Figure 1 The base station 110 is shown. In some aspects, Figure 3 The UE 355 shown may be Figure 1 and / or Figure 2 UE 120 is shown.

[0053] As shown in the figure numeral 365, in some aspects, the radio access network including the IAB network may utilize millimeter wave technology and / or directional communication (e.g., beamforming, etc.) to communicate 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, the wireless backhaul link 370 between base stations may use millimeter wave signals to carry information and / or may be directed to a target base station using beamforming, etc. Similarly, the wireless access circuit 375 between the UE and the base station may use millimeter wave signals and / or may be directed to a target wireless node (e.g., a UE and / or a base station). In this way, inter-link interference may be reduced.

[0054] Figure 3 The configuration of the base station and UE in is shown as an example, and other examples are contemplated. For example, Figure 3 The one or more base stations illustrated in the figure may be replaced by one or more UEs communicating via a UE-to-UE access network (e.g., a point-to-point network, a device-to-device network, etc.). In this case, the anchor node may refer to a UE that directly communicates with a base station (e.g., an anchor base station or a non-anchor base station).

[0055] As indicated above, Figure 3 are provided as examples. Other examples may differ from those described in Figure 3 An example of description.

[0056] Figure 4 is a diagram illustrating an example 400 of an IAB network architecture in accordance with various aspects of the present disclosure.

[0057] 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 at the core network. Additionally or alternatively, the IAB donor 405 may be connected 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 in conjunction with Figure 3 As described. As shown in the figure, the IAB donor 405 may include a central unit (CU) that may perform an access node controller (ANC) function, an AMF function, etc. The CU may configure a distributed unit (DU) of the IAB donor 405 and / or may configure one or more IAB nodes 410 (e.g., an MT and / or DU of the IAB node 410) connected to the core network via the IAB donor 405. Therefore, the CU of the IAB donor 405 may control and / or configure the entire IAB network connected to the core network via the IAB donor 405, such as by using a control message and / or a configuration message (e.g., a radio resource control (RRC) configuration message, an F1 application protocol (F1AP) message, etc.).

[0058] like Figure 4As further shown in FIG. 4 , 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 an IAB Donor 405 . As shown, the IAB node 410 may include a mobile terminal (MT) function (sometimes also referred to as a UE function (UEF), and may include a DU function (sometimes also 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 the child node) and / or an 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 the parent node) and / or a UE 120. Thus, the DU may be referred to as a scheduling node or a scheduling component, and the MT may be referred to as a scheduling node or a scheduling component. In some aspects, the IAB donor 405 may include the DU function without the MT function. That is, the IAB donor 405 may configure, control and / or schedule the communication of the IAB node 410 and / or the UE 120. The UE 120 may include only the MT function without the DU function. That is, the UE Communications of UE 120 may be controlled and / or scheduled by IAB donor 405 and / or IAB node 410 (eg, a parent node of UE 120).

[0059] When the first node controls and / or schedules the second node to communicate (for example, when the first node provides the DU function for the MT function of the second node), the first node may be referred to as the parent node of the second node, and the second node may be referred to as the child node of the first node. The child node of the second node may be referred to as the grandchild node of the first node. Therefore, the DU function of the parent node may control and / or schedule the communication of the child node of the parent node. The parent node may be the IAB donor 405 or the IAB node 410, and the child node may be the IAB node 410 or the UE 120. The communication of the MT function of the child node may be controlled and / or scheduled by the parent node of the child node.

[0060] like Figure 4 As further shown in FIG. 4 , the link between UE 120 (e.g., which has only MT functionality but not DU functionality) and IAB donor 405, or the link between UE 120 and IAB node 410 may be referred to as access circuit 415. Access circuit 415 may be a wireless access circuit that provides radio access to the core network to UE 120 via IAB donor 405 and optionally via one or more IAB nodes 410. Thus, Figure 4 The network shown may be referred to as a multi-hop network or a wireless multi-hop network.

[0061] like Figure 4As further shown in , the link between the IAB donor 405 and the IAB node 410 or 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 radio access to the core network to the IAB node 410 via the IAB donor 405 and optionally via one or more other IAB nodes 410. In some aspects, the backhaul link 420 may be a primary backhaul link or an auxiliary backhaul link (e.g., a backup backhaul link). In some aspects, the auxiliary backhaul link may be used if the primary backhaul link fails, becomes congested, becomes overloaded, etc. For example, if the primary backhaul link between the IAB-node 2 and the IAB-node 1 fails, the backup link 425 between the IAB-node 2 and the IAB-node 3 may be used for backhaul communication. As used herein, a node or a wireless node may refer to the IAB donor 405 or the IAB node 410.

[0062] In the IAB network, network resources (e.g., time resources, frequency resources, space resources, etc.) used for wireless communication can be shared between the access circuit 415 and the backhaul link 420. In some cases, the CU of the IAB donor 405 can configure the resource mode for the IAB node 410 in the IAB network. For example, the time resource can be configured as downlink only, uplink only, flexible or unavailable (e.g., non-available). When the time resource is configured to be used only for the downlink of the wireless node, the time resource can be used only for the downlink communication of the wireless node, but not for the uplink communication. Similarly, when the time resource is configured to be used only for the uplink of the wireless node, the time resource can be used only for the uplink communication of the wireless node, but not for the downlink communication. When the time resource is configured to be flexible for the wireless node, the time resource can be used for both the downlink communication and the uplink communication of the wireless node. When the time resource is configured to be unavailable for the wireless node, the time resource may not be used for any communication of the wireless node.

[0063] The time resources configured as downlink-only, uplink-only, or flexible in the IAB network may be further configured as hard resources or soft resources. When a time resource is configured as a hard resource for a wireless node, the time resource is always available for communication by the wireless node. For example, a hard downlink-only time resource is always available for downlink-only communication of the wireless node, a hard uplink-only time resource is always available for uplink-only communication of the wireless node, and a hard flexible time resource is always available for uplink and downlink communication of the wireless node.

[0064] 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 (e.g., explicitly or implicitly) indicate whether the soft time resource is available for communication of the wireless node. Therefore, the soft time resource may be in one of the following two states: a schedulable state (e.g., when the soft time resource is available for scheduling and / or communication of the wireless node) and an unschedulable state (e.g., when the soft time resource is not available for scheduling of the wireless node and is not available for communication of the wireless node). For example, the soft downlink-only time resource is available for downlink communication of the wireless node only when the parent node of the wireless node indicates that the soft downlink-only time resource is available. Similarly, the soft uplink-only time resource is available for uplink communication of the wireless node only when the parent node of the wireless node indicates that the soft uplink-only time resource is available. The soft flexible time resource is available for uplink and downlink communication of the wireless node only when the parent node of the wireless node indicates that the soft flexible time resource is available.

[0065] In some cases, the nodes of the IAB network are subject to half-duplex constraints, which means that a particular node cannot send and receive information at the same time (e.g., cannot communicate synchronously or simultaneously via the node's access circuit 415 and the node's backhaul link 420). This constraint may result in high latency for communication. In order to allow communication via both the node's access circuit 415 and the backhaul link 420, the node may be configured with resource allocation using time division multiplexing (TDM), where the access circuit 415 and the communication on the backhaul link 420 are scheduled to occur at different times. However, this may increase the latency of the communication compared to simultaneous communication via the access circuit 415 and the backhaul link 420.

[0066] 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 for communication, and in the event that one of the backhaul links 420 fails, none of the backhaul links 420 is used as a backup link 425. However, if TDM is used across multiple backhaul links 420 and one or more access circuits 415, latency may increase if simultaneous communication across multiple links is not enabled. Some techniques and devices described herein enable an IAB node to communicate simultaneously via multiple links, such as multiple backhaul links 420, multiple access circuits 415, or one or more backhaul links 420 and one or more access circuits 415.

[0067] However, depending on the architecture and / or hardware configuration of the IAB node, different IAB nodes may have different capabilities for simultaneous communication, such as whether the IAB node supports full-duplex communication, the level of self-interference generated by the transmission of the IAB node, the ability of the IAB node to suppress and / or eliminate such self-interference (e.g., using filtering), the number of transmit chains and / or receive chains of the IAB node, whether multiple antennas of the IAB node share such transmit chains and / or receive chains, the operating frequency or bandwidth of the IAB node, the beamforming capability or configuration of the IAB node, etc. In addition, depending on the network conditions and / or transmission parameters of the simultaneous communication, different IAB nodes may have different capabilities for simultaneous communication, such as the beamforming direction associated with the simultaneous communication, the transmission power of the simultaneous communication, whether such simultaneous communication is synchronized, the frequency of the cell via which the IAB node can communicate, etc. Some techniques and devices described herein enable the IAB node to signal that the IAB node is capable of simultaneous communication via multiple links, which may be subject to the constraints of one or more conditions. In this way, the IAB node can reduce latency, improve reliability, improve spectrum efficiency, etc. by utilizing simultaneous communication according to the capabilities of the IAB node.

[0068] As indicated above, Figure 4 are provided as examples. Other examples may differ from those described in Figure 4 An example of description.

[0069] Figure 5 5 is a diagram illustrating an example 500 of simultaneous communication capability signaling in an IAB network according to various aspects of the present disclosure. Figure 5 As shown, the IAB network may include an IAB donor 405 and one or more IAB nodes 410, the one or more IAB nodes 410 being shown as a first IAB node 410-1, the first IAB node being a child node of both a second IAB node 410-2 and a third IAB node 410-3. Below, the first IAB node 410-1 will be referred to as a child node, the second IAB node 410-2 will be referred to as a first parent node (which is shown as parent node 1 or P1), and the third IAB node 410-3 will be referred to as a second parent node (which is shown as parent node 2 or P2). Although the child node is shown as an IAB node, in some aspects, the child node may be a UE 120.

[0070] As shown at reference numeral 505, the child node may determine the ability of the child node to communicate simultaneously. The ability may be the ability to communicate simultaneously with respect to 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 ability may include the ability to communicate simultaneously with multiple parent nodes of the child node, as described below in conjunction with Figure 6Additionally or alternatively, the capability may be the ability to use multiple MT components of a subnode to communicate simultaneously, as described below in conjunction with Figure 7 Additionally or alternatively, the capability may be the ability to communicate simultaneously using multiple TRPs of a child node, as described below in conjunction with Figure 8 Described in more detail.

[0071] In some aspects, the capability may be to communicate simultaneously using different or multiple RATs. For example, the child node may indicate the capability for simultaneous communication using a dual connectivity mode utilizing 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 to communicate using a single RAT. For example, the capability may be to communicate simultaneously using only NRRAT.

[0072] In some aspects, the ability to communicate simultaneously may be subject to the constraints of one or more conditions. In some aspects, the child node may determine and / or identify the condition. Additionally or alternatively, the child node may determine whether the ability to communicate simultaneously is conditional (e.g., subject to the constraints of the condition) or unconditional (e.g., not subject to the constraints of the condition). In some aspects, the condition 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 suppress and / or eliminate such self-interference, the number of transmission chains and / or receiving chains of the child node, whether such transmission chains and / or receiving chains are shared by multiple antennas of the child node, etc. Additionally or alternatively, the condition may depend on network conditions and / or transmission parameters associated with simultaneous communication, such as beamforming directions associated with simultaneous communication, transmission power of simultaneous communication, whether such simultaneous communication is synchronized, etc.

[0073] In some aspects, the condition may depend on the transmit power associated with one or more simultaneous communications, the receive power associated with one or more simultaneous communications, the transmit timing associated with one or more simultaneous communications, the receive timing associated with one or more simultaneous communications, the resource allocation of one or more simultaneous communications (e.g., time domain resource allocation, frequency domain resource allocation, spatial domain resource allocation, etc.), the transmit frequency associated with one or more simultaneous communications, the receive frequency associated with one or more simultaneous communications, the resource block separation between multiple simultaneous communications, the frequency separation between multiple simultaneous communications, the beam direction associated with one or more simultaneous communications, the channel type associated with one or more simultaneous communications (e.g., physical downlink control channel (PDCCH), physical downlink shared channel (PDSCH), physical uplink shared channel (PUSCH), physical uplink control channel (PUCCH), etc.), the MCS associated with one or more simultaneous communications, the rank associated with one or more simultaneous communications (e.g., as indicated by a rank indication), etc.

[0074] As shown at 510, a child node may send an indication of the child node's ability to communicate simultaneously (sometimes referred to as a capability indication). In some aspects, the child node may send the indication of the capability to a parent node or multiple parent nodes of the child node, such as Figure 5 As shown. Additionally or alternatively, the child node may send an indication of the capability to the IAB donor 405 (e.g., a CU of the IAB donor 405), such as via an F1 interface (e.g., an F1 application protocol (F1-AP) interface). In some aspects, the parent node of the child node may send or relay the indication of the capability to the IAB donor 405, or send or relay the indication of the capability to the IAB donor 405. The child node may send the indication of the capability 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.

[0075] In some aspects, the child node may send an indication of the capability based at least in part on receiving a reporting configuration from a control node (e.g., a parent node of the child node, IAB donor 405, etc.). The reporting configuration may request the capability indication, may indicate one or more resources for sending the indication of the capability, may indicate a periodicity for sending the indication of the capability, 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 the capability of simultaneous communication is to be reported, etc. The reporting configuration may be sent semi-statically (e.g., in an RRC message) and / or dynamically (e.g., in a downlink control message).

[0076] In some aspects, a child node may send an indication of the capability for simultaneous communication for all combinations of parent nodes with which the child node is communicating (e.g., all combinations of parent nodes to which the child node is connected, which parent nodes have established RRC connections, etc.). Similarly, in some aspects, a child node may send an indication of the capability for simultaneous communication for all combinations of MT components included in the child node. Similarly, in some aspects, a child node may send an indication of the capability for simultaneous communication for all combinations of TRPs included in the child node.

[0077] Alternatively, the child node may send an indication of the capability for simultaneous communication for a subset of the parent node with which the child node is communicating, for a subset of the MT components included in the child node, and / or for a subset of the TRPs included in the child node. In some aspects, a subset (or a corresponding subset) may be indicated in a report configuration.

[0078] In some aspects, a child node may send (e.g., using a capability indication) an indication of whether the child node's capability for simultaneous communication is subject to a conditional constraint (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 conditional constraint (e.g., is unconditional), and a second value of the bit (e.g., 1) may indicate that the capability is subject to a conditional constraint (e.g., is conditional). In some aspects, the indication of whether the capability for simultaneous communication is conditional or unconditional includes an indication of the condition to which the simultaneous communication performed by the child node is subject. Exemplary conditions are as described above.

[0079] As shown in reference numeral 515, the child node may communicate with another node in the IAB network based at least in part on the child node's ability to communicate simultaneously. The other node may include, for example, a control node that configures and / or schedules resources for the child node, such as a parent node of the child node (e.g., a DU of the parent node), an IAB donor 405 (e.g., a CU and / or DU of the IAB donor 405), etc. For example, the control node may send a configuration to the child node based at least in part on the ability and / or may schedule resources for the child node (e.g., by sending a resource allocation to the child node). In some aspects, a capability indication may be sent to and received by a CU of the IAB donor 405, and the CU may send or relay the capability indication to one or more parent nodes of the child node, or send or relay the capability indication to one or more parent nodes of the child node. Additionally or alternatively, the CU may send the configuration and / or resource allocation to the parent node of the child node, or send the configuration and / or resource allocation to the parent node of the child node, and the parent node may send or relay the configuration and / or resource allocation to the child node, or send or relay the configuration and / or resource allocation to the child node.

[0080] For example, if the child node is capable of communicating with multiple parent nodes simultaneously, the control node may schedule resources for the first parent node that are also scheduled for the second parent node. In addition, the child node may send simultaneous communications in the scheduled resources. In some aspects, the child node may communicate with multiple parent nodes of the child node simultaneously based at least in part on the capabilities using multiple MT components of the child node and / or using multiple TRPs of the child node, such as in conjunction with Figures 6 to 9 Described in more detail.

[0081] In some aspects, the child node may receive configuration or resource allocation based on capability indication at least in part, and may not be able to support the configuration or resource allocation. For example, the simultaneous communication performed by the child node may be subject to the constraint of the condition, and the configuration or resource allocation may violate the condition (for example, because the child node does not indicate that the simultaneous communication is subject to the constraint of the condition, because the child node does not indicate the condition, or because of error, etc.). In this case, the child node may send the indication that the child node does not support configuration or resource allocation. In some aspects, if the child node does support configuration or resource allocation, the child node may send the indication that the child node supports configuration or resource allocation. The child node may send the indication that the child node supports configuration or resource allocation to the control node, such as a parent node or an IAB donor 405.

[0082] As a more 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 communicating with a first parent node of the child node, for communicating using a first MT component of the child node, and / or for communicating 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 communicating with a second parent node of the child node, for communicating using a second MT component of the child node, and / or for communicating 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 conditions associated with a capability for simultaneous communication. Based at least in part on this determination, the child node may send (e.g., in uplink control information (UCI)) an indication that the child node is unable to communicate using the first set of resources.

[0083] By enabling an IAB node to signal an IAB node for simultaneous communication via multiple links, and thereafter using the capability of the multiple links for simultaneous communication, some techniques and apparatuses described herein may reduce latency, improve throughput, increase reliability, improve spectral efficiency, etc. by utilizing simultaneous communication according to the capability of the IAB node. In addition, 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] As indicated above, Figure 5 are provided as examples. Other examples may differ from those described in Figure 5 An example of description.

[0085] Figure 6 600 is a diagram illustrating an example of simultaneous communication capability signaling in an IAB network according to various aspects of the present disclosure. Example 600 relates to capability signaling for simultaneous communication with multiple parent nodes. Figure 5 , the IAB network may include an IAB donor 405 and one or more IAB nodes 410, the one or more IAB nodes 410 are shown as a first IAB node 410-1, the first IAB node 410-1 is a child node of both a second IAB node 410-2 and a third IAB node 410-3. Below, the first IAB node 410-1 will be referred to as a child node, the second IAB node 410-2 will be referred to as a first parent node (which is shown as parent node 1 or P1), and the third IAB node 410-3 will be referred to as a second parent node (which is shown as parent node 2 or P2). Although the child node is shown as an IAB node, in some aspects, the child node can be a UE 120.

[0086] As shown in reference numeral 605, the child node may determine the child node's ability to communicate simultaneously. In example 600, the ability is the ability to communicate simultaneously with multiple parent nodes of the child node. For example, the ability may be the ability of the child node to communicate simultaneously with multiple parent nodes of the child node. Figure 5 As described, the capability to communicate simultaneously with multiple parent nodes may be available on a single RAT, available on multiple RATs (eg, a first RAT for a first parent node and a second RAT for a second parent node), and / or may be subject to conditional constraints.

[0087] As shown at 610, a child node may send an indication of the child node's ability to communicate with multiple parent nodes simultaneously, as described above in conjunction with Figure 5 For example, the capability indication may indicate whether the child node supports simultaneous transmission to multiple parent nodes of the child node, such as simultaneous transmission from the MT of the child node to a first parent node and simultaneous transmission from the MT of the child node to a second parent node, which is shown as MT-TX to P1 and 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 from a first parent node through the MT of the child node and simultaneous reception from a second parent node through the MT of the child node, which is shown as MT-RX from P1 and MT-RX from P2. Additionally or alternatively, the capability indication may indicate whether the child node supports simultaneous transmission to a first parent node of the child node and simultaneous reception from a second parent node of the child node, such as simultaneous transmission to the first parent node by the child node's MT and simultaneous reception from the second parent node by the child node's MT (which is shown as MT-TX to P1 and MT-RX from P2) or simultaneous reception from the first parent node by the child node's MT and simultaneous transmission to the second parent node by the child node's MT (which is shown as MT-RX from P1 and MT-TX to P2).

[0088] In some aspects, the capability indication may be a bitmap where each bit corresponds to a combination of simultaneous transmissions and / or simultaneous receptions for a parent node. Alternatively, the capability indication may be an index value where different index values ​​map to different combinations of simultaneous transmissions and / or simultaneous receptions for a parent node. In some aspects, the capability indication may identify parent nodes with which a node can communicate simultaneously (e.g., shown as P1 and P2, but may include a cell identifier, a node identifier, an IAB node identifier, a base station identifier, etc.).

[0089] In some aspects, the ability of a child node to communicate simultaneously may be applied to both parent nodes of the child node, such as Figure 6Alternatively, the child node's ability to communicate simultaneously may apply to more than two parent nodes of the child node, such as three parent nodes of the child node: P1, P2, and P3 (not shown). In this case, the child node may report simultaneous communication for multiple pairs of parent nodes (such as for P1 and P2 (described above and Figure 6 as shown), for P1 and P3 (similar to the above and Figure 6 , but replace P2 with P3) and for P2 and P3 (similar to above and Figure 6 , but replacing P1 with P3)) simultaneously combined capability. Additionally or alternatively, a child node may indicate the capability to communicate simultaneously with more than two parent nodes. 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, to simultaneously transmit to a second parent node using the child node's MT, and to simultaneously receive from a third parent node using the child node's MT (e.g., MT-TX to P1 and MT-TX to P2 and MT-RX from P3).

[0090] In some aspects, a child node may indicate the capabilities of all combinations of parent nodes for simultaneous communication (eg, all combinations of simultaneous transmit and simultaneous receive capabilities of all combinations of parent nodes). For example, for three parent nodes (P1, P2 and P3), the child node may indicate one or more of the following capabilities: MT-TX to P1, MT-TX to P2 and MT-TX to P3, MT-TX to P1, MT-TX to P2 and MT-RX from P3, MT-TX to P1, MT-RX from P2 and MT-TX to P3, MT-RX from P1, MT-TX to P2 and MT-TX to P3, MT-TX to P1 and MT-RX from P2 and MT-RX from P3, MT-RX from P1, MT-RX from P2 and MT-TX to P3, MT-RX from P1, MT-RX from P2 and MT-TX to P3, MT-RX from P1, MT-RX from P2 and MT-TX to P3, MT-RX from P1, MT-TX to P2 and MT-RX from P3, and / or MT-RT from P1, MT-RX from P2 and MT-RX from P3. Alternatively, a child node may indicate a subset of parent nodes of more than two parent nodes for simultaneous communication capabilities. In some aspects, the subset may be a subset that includes only those combinations of parent nodes with which the child node can communicate simultaneously (rather than any combination of parent nodes with which the child node cannot communicate simultaneously). Additionally or alternatively, the subset may be indicated and / or requested in a report configuration.

[0091] As shown at 615, the child node may communicate with another node (eg, a control node, such as a parent node or a CU) in the IAB network based at least in part on the child node's ability to communicate simultaneously, as described above in conjunction with Figure 5Description. For example, the control node may send a configuration to the child node based at least in part on the capability and / or may schedule resources for the child node (e.g., by sending a resource allocation to the child node). For example, if the 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, etc.) for the first parent node, which are also scheduled for the second parent node. In addition, the child node may send simultaneous communications in the scheduled resources. For example, a child node may communicate with multiple parent nodes of the child node simultaneously.

[0092] By enabling an IAB node to signal the ability of the IAB node to communicate simultaneously with multiple parent nodes and thereafter communicate simultaneously with the multiple parent nodes, some techniques and apparatus described herein may reduce latency, improve throughput, increase reliability, improve spectral efficiency, etc. by utilizing simultaneous communications according to the capabilities of the IAB node. Additionally, by utilizing the ability to configure the IAB node and / or schedule resources for the IAB node, configuration errors and / or resource scheduling conflicts may be reduced.

[0093] As indicated above, Figure 6 are provided as examples. Other examples may differ from those described in Figure 6 An example of description.

[0094] Figure 7 700 is a diagram illustrating an example of simultaneous communication capability signaling in an IAB network according to various aspects of the present disclosure. Example 700 relates to capability signaling for simultaneous communication using multiple MT components (e.g., multiple MTs or multiple MT functions) of a child node. Figure 5 , the IAB network may include an IAB donor 405 and one or more IAB nodes 410, the one or more IAB 410 nodes are shown as a first IAB node 410-1, the first IAB node 410-1 is a child node of both a second IAB node 410-2 and a third IAB node 410-3. Below, the first IAB node 410-1 will be referred to as a child node, the second IAB node 410-2 will be referred to as a first parent node (which is shown as parent node 1 or P1), and the third IAB node 410-3 will be referred to as a second parent node (which is shown as parent node 2 or P2). Although the child node is shown as an IAB node, in some aspects, the child node can be a UE 120.

[0095] like Figure 7 As shown, the child node may include multiple MT components, which are shown as a first MT component MT1 and a second MT component MT2. As shown, the first MT component can be used to communicate with the first parent node, and the second MT component can be used to communicate with the second parent node. Therefore, different MT components of the child node can communicate with different parent nodes of the child node.

[0096] As shown in reference numeral 705, the child node may determine a capability of the child node for simultaneous communication. In example 700, the capability is an ability of multiple MT components of the child node to communicate simultaneously. For example, the capability may be an ability of the child node to communicate simultaneously using multiple MT components of the child node. Figure 5 As described, the capability to communicate simultaneously using multiple MT components may be used for a single RAT, may be used for multiple RATs (eg, a first RAT for a first MT component and a second RAT for a second MT component), and / or may be subject to conditions.

[0097] As shown at reference numeral 710, a subnode may send an indication of the subnode's ability to use multiple MT components for simultaneous communication, as described above in conjunction with Figure 5 Description. For example, the capability indication may indicate whether the subnode supports simultaneous transmission through multiple MT components of the subnode, such as simultaneous transmission through the first MT component of the subnode and simultaneous transmission through the second MT component of the subnode, which is shown as MT1-TX and MT2-TX. Additionally or alternatively, the capability indication may indicate whether the subnode supports simultaneous reception through multiple MT components of the subnode, such as simultaneous reception through the first MT component of the subnode and simultaneous reception through the second MT component of the subnode, which is shown as MT1-RX and MT2-RX. Additionally or alternatively, the capability indication may indicate whether the subnode supports simultaneous transmission through the first MT component of the subnode and simultaneous reception through the second MT component of the subnode, such as simultaneous transmission through the first MT component of the subnode and simultaneous reception through the second MT component of the subnode (which is shown as MT1-TX and MT2-RX), or simultaneous reception through the first MT component of the subnode and simultaneous transmission through the second MT component of the subnode (which is shown as MT1-RX and MT2-TX).

[0098] In some aspects, the capability indication may be a bitmap, where each bit corresponds to a combination of simultaneous transmission and / or simultaneous 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 simultaneous reception for a combination of MT components. In some aspects, the capability indication may identify MT components with which the node is capable of communicating simultaneously (e.g., shown as MT1 and MT2, but it may include a cell identifier, a node identifier, an IAB node identifier, a base station identifier, etc.).

[0099] In some aspects, the ability of a subnode to communicate simultaneously may be applied to two MT components of the subnode, such as Figure 7Alternatively, the subnode's ability to communicate simultaneously may apply to more than two MT components of the subnode. In this case, the subnode may report information for multiple pairs of MT components (such as for MT1 and MT2 (described above and Figure 7 ), for MT1 and MT3 (similar to the above and Figure 7 , but replace MT2 with MT3) and for MT2 and MT3 (similar to above and Figure 7 , but replacing MT1 with MT3)) simultaneous combination capability. Additionally or alternatively, a subnode may indicate the ability to use more than two MT components for simultaneous communication. For example, a subnode may indicate that the subnode has the ability to simultaneously transmit using the first MT component of the subnode, to simultaneously transmit using the second MT component of the subnode, and to simultaneously receive using the third MT component of the subnode (e.g., MT1-TX and MT2-TX and MT3-RX).

[0100] In some aspects, the subnode may indicate the capability of all combinations of MT components to communicate simultaneously (e.g., all combinations of simultaneous transmission and simultaneous reception capabilities of all combinations of MT components). For example, for three MT components (MT1, MT2, and MT3), the subnode may indicate one or more of the following capabilities: MT1-TX and MT2-TX and MT3-TX, MT1-TX and MT2-TX and MT3-RX, MT1-TX and MT2-RX and MT3-TX, MT1-RX and MT2-TX and MT3-TX, MT1-TX and MT2-RX and MT3-RX, MT1-RX and MT2-RX and MT3-TX, MT1-RX and MT2-RX and MT3-TX, MT1-RX and MT2-TX and MT3-RX, and / or MT1-RX and MT2-RX and MT3-RX. Alternatively, the subnode may indicate the capability of a subset of the MT components of the more than two MT components to communicate simultaneously. In some aspects, the subset may be a subset that includes only those combinations of MT components with which the child node can communicate simultaneously (rather than any combination of MT components with which the child node cannot communicate simultaneously). Additionally or alternatively, the subset may be indicated and / or requested in a report configuration.

[0101] As shown at 715, the child node may communicate with another node (eg, a control node, such as a parent node or a CU) in the IAB network based at least in part on the child node's ability to communicate simultaneously, as described above in conjunction with Figure 5Description. For example, the control node may send a configuration to the child node based at least in part on the capability and / or may schedule resources for the child node (e.g., by sending a resource allocation to the child node). As an example, if the child node is capable of using multiple MT components for communication simultaneously, the control node may schedule resources (e.g., time resources, frequency resources, or space resources, etc.) for the first MT component of the child node, which are also scheduled for the second MT component of the child node. In addition, the child node may send simultaneous communications in the scheduled resources. For example, the child node may use multiple MT components of the child node for simultaneous communication.

[0102] By enabling an IAB node to signal the ability of the IAB node to communicate with multiple MT components simultaneously and thereafter use the multiple MT components to communicate simultaneously, some techniques and apparatuses described herein may reduce latency, improve throughput, increase reliability, improve spectral efficiency, etc. by utilizing simultaneous communications according to the capabilities of the IAB node. Additionally, by using the ability to configure the IAB node and / or schedule resources for the IAB node, configuration errors and / or resource scheduling conflicts may be reduced.

[0103] As indicated above, Figure 7 are provided as examples. Other examples may differ from those described in Figure 7 An example of description.

[0104] Figure 8 8 is a diagram illustrating an example 800 of simultaneous communication capability signaling in an IAB network according to various aspects of the present disclosure. Example 800 relates to capability signaling using multiple TRPs of a subnode (or multiple panels of a subnode) for simultaneous communication. Figure 5 , the IAB network may include an IAB donor 405 and one or more IAB nodes 410, the one or more IAB nodes 410 are shown as a first IAB node 410-1, the first IAB node 410-1 is a child node of both a second IAB node 410-2 and a third IAB node 410-3. Below, the first IAB node 410-1 will be referred to as a child node, the second IAB node 410-2 will be referred to as a first parent node (which is shown as parent node 1 or P1), and the third IAB node 410-3 will be referred to as a second parent node (which is shown as parent node 2 or P2). Although the child node is shown as an IAB node, in some aspects, the child node may be a UE 120.

[0105] like Figure 8As shown, the MT component of the child node may include multiple TRPs, which are 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, which are 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 the first parent node, and the second MT-TRP may be used to communicate with the second parent node. Therefore, 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 the first child node, and the second DU-TRP may be used to communicate with the second child node. Therefore, different DU-TRPs of the child node may communicate with different child nodes of the child node.

[0106] As shown in reference numeral 805, the child node may determine a capability of the child node for simultaneous communication. In example 800, the capability is the capability of simultaneous communication relative to multiple TRPs of the child node. For example, the capability may be the capability of the child node to communicate simultaneously using multiple TRPs of the child node. Figure 5 As described, the ability to communicate simultaneously using multiple TRPs may be used for a single RAT, may be used 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.

[0107] As shown in reference numeral 810, a child node may send an indication of the child node's ability to use multiple TRPs for simultaneous communications, as described above in conjunction with Figure 5 Description. For example, the capability indication may indicate whether the subnode supports simultaneous transmission through multiple TRPs of the subnode, such as transmission through a first TRP of the subnode and through a second TRP of the subnode. Additionally or alternatively, the capability indication may indicate whether the subnode supports simultaneous reception through multiple TRPs of the subnode, such as simultaneous reception through a first TRP of the subnode and through a second TRP of the subnode. Additionally or alternatively, the capability indication may indicate whether the subnode supports simultaneous transmission through a first TRP of the subnode and simultaneous reception through a second TRP of the subnode, such as simultaneous transmission through the first TRP of the subnode and simultaneous reception through the second TRP of the subnode, or simultaneous reception through the first TRP of the subnode and simultaneous transmission through the second TRP of the subnode.

[0108] Additionally or alternatively, the capability indication may indicate whether the subnode supports simultaneous communication of a TRP through the MT component of the subnode and a TRP of the DU of the subnode, which is shown as (e.g., for simultaneous transmission) MT-TX and DU-TRP1-TX. Additionally or alternatively, the capability indication may indicate whether the subnode supports simultaneous communication of a TRP through the DU of the subnode and a TRP of the MT component of the subnode, which is shown as (e.g., for simultaneous transmission) MT-TRP1-TX and DU-TX. Additionally or alternatively, the capability indication may indicate whether the subnode supports simultaneous communication of a TRP through the DU of the subnode and a TRP of the MT component of the subnode, which is shown as (e.g., for simultaneous transmission) MT-TRP1-TX and DU-TRP1-TX. Additionally or alternatively, the capability indication may indicate whether the subnode supports simultaneous communication through a first TRP of the MT component of the subnode and a second TRP of the MT component of the subnode, which is shown as (e.g., for simultaneous transmission) MT-TRP1-TX and MT-TRP2-TX. Additionally or alternatively, the capability indication may indicate whether the subnode supports simultaneous communication through a first TRP of the DU of the subnode and a second TRP of the DU of the subnode, which is shown as (e.g., for simultaneous transmission) DU-TRP1-TX and DU-TRP2-TX. Although these examples show indications of support for simultaneous transmission, the subnode may indicate support for simultaneous reception, or simultaneous transmission and reception, in a similar manner.

[0109] In some aspects, the capability indication may be a bitmap where each bit corresponds to a combination of simultaneous transmission and / or simultaneous reception for a 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 simultaneous reception for a combination of TRPs. In some aspects, the capability indication may identify the TRPs with which the node is able to communicate simultaneously (e.g., shown as MT-TRP1, MT-TRP2, DU-TRP1, and DU-TRP2, but it may include a cell identifier, a node identifier, an IAB node identifier, a base station identifier, a TRP identifier, etc.).

[0110] In some aspects, the ability of a subnode to communicate simultaneously may be applied to two TRPs of the subnode (eg, each MT or each DU), such as Figure 8As shown. Alternatively, the subnode's capability for simultaneous communication may apply to more than two TRPs of the subnode (e.g., per MT or per DU). In this case, the subnode may report simultaneous combined capabilities for multiple pairs of TRPs (such as for MT-TRP1 and MT-TRP2, for MT-TRP1 and MT-TRP3, and for MT-TRP2 and MT-TRP3). Additionally or alternatively, the subnode may indicate the ability to communicate simultaneously using more than two TRPs. For example, the subnode may indicate that the subnode has the ability to simultaneously transmit using the subnode's first TRP, simultaneously transmit using the subnode's second TRP, and simultaneously receive using the subnode's third TRP (e.g., MT-TRP1-TX and MT-TRP2-TX and MT-TRP3-RX).

[0111] In some aspects, a child node may indicate the capabilities of all combinations of TRPs to communicate simultaneously (e.g., all combinations of simultaneous transmit and simultaneous receive capabilities of all combinations of TRPs). For example, for the three TRPs of the MT component (MT-TRP1, MT-TRP2, and MT-TRP3), the subnode may indicate one or more of the following capabilities: MT-TRP1-TX and MT-TRP2-TX and MT-TRP3-TX, MT-TRP1-TX and MT-TRP2-TX and MT-TRP3-RX, MT-TRP1-TX and MT-TRP2-RX and MT-TRP3-TX, MT-TRP1-RX and MT-TRP2-TX and MT-TRP3-TX, MT-TRP1-RX and MT-TRP2-RX and MT-TRP3-TX, MT-TRP1-RX and MT-TRP2-RX and MT-TRP3-RX, MT-TRP1-RX and MT-TRP2-RX and MT-TRP3-TX, MT-TRP1-RX and MT-TRP2-TX and MT-TRP3-RX, and / or MT-TRP1-RX and MT-TRP2-RX and MT-TRP3-RX. Alternatively, the child node may indicate the ability of a subset of the more than two TRPs to communicate simultaneously. In some aspects, the subset may be a subset that includes only those combinations of TRPs with which the child node is able to communicate simultaneously (rather than any combination of TRPs with which the child node is not able to communicate simultaneously). Additionally or alternatively, the subset may be indicated and / or requested in a report configuration.

[0112] As shown at 815, the child node may communicate with another node (eg, a control node, such as a parent node or a CU) in the IAB network based at least in part on the child node's ability to communicate simultaneously, as described above in conjunction with Figure 5Description. For example, the control node may send a configuration to the child node based at least in part on the capability and / or may schedule resources for the child node (e.g., by sending a resource allocation to the child node). As an example, if the child node is capable of communicating using multiple TRPs simultaneously, the control node may schedule resources (e.g., time resources, frequency resources, or space resources, etc.) for the first TRP of the child node, which are also scheduled for the second TRP of the child node. In addition, the child node may send simultaneous communications in the scheduled resources. For example, the child node may communicate simultaneously using multiple TRPs of the child node.

[0113] By enabling an IAB node to signal the ability of the IAB node to communicate simultaneously with multiple TRPs and thereafter use the multiple TRPs for simultaneous communication, some techniques and apparatus described herein may reduce latency, improve throughput, increase reliability, improve spectral efficiency, etc. by utilizing simultaneous communications based on the capabilities of the IAB node. Additionally, by utilizing the ability to configure the IAB node and / or schedule resources for the IAB node, configuration errors and / or resource scheduling conflicts may be reduced.

[0114] As above combined Figure 5 Description, in some aspects, a child node may indicate the ability to communicate simultaneously 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. Figure 6 , Figure 7 and Figure 8 The invention may be described in conjunction with two or more of the techniques described in the specification to indicate a combination of capabilities, such as the ability to communicate simultaneously with multiple parent nodes using multiple MT components, the ability to communicate simultaneously with multiple parent nodes using multiple TRPs, the ability to communicate simultaneously with multiple MT components and using multiple TRPs (for example, where each MT component may include one or more TRPs), or the ability to communicate simultaneously with multiple parent nodes using multiple MT components and using multiple TRPs.

[0115] As indicated above, Figure 8 are provided as examples. Other examples may differ from those described in Figure 8 An example of description.

[0116] Fig. 9 900 is a diagram illustrating an example of simultaneous communication capability signaling in an IAB network according to various aspects of the present disclosure. Example 900 relates to capability signaling for simultaneous communication using multiple cells of a subnode, multiple TRPs of a subnode (or multiple panels of a subnode), etc. Figure 5, the IAB network may include an IAB donor 405 and one or more IAB nodes 410, the one or more IAB nodes 410 are shown as a first IAB node 410-1, the first IAB node 410-1 is a child node of both a second IAB node 410-2 and a third IAB node 410-3. Below, the first IAB node 410-1 will be referred to as a child node, the second IAB node 410-2 will be referred to as a first parent node (which is shown as parent node 1 or P1), and the third IAB node 410-3 will be referred to as a second parent node (which is shown as parent node 2 or P2). Although the child node is shown as an IAB node, in some aspects, the child node can be a UE 120.

[0117] like Fig. 9 As shown, the DU component of the subnode may be able to communicate using multiple cells (which are shown as a first cell (e.g., cell 1 or DU-Cell1) and a second cell (e.g., cell 2 or DU-Cell2)). In some aspects, the first cell can be used to communicate with the first subnode, and the second cell can be used to communicate with the second subnode. Alternatively, both the first cell and the second cell can be used to communicate with a single subnode (e.g., using different component carriers). Therefore, different cells of a subnode can communicate with different subnodes of the subnode or the same subnode of the subnode.

[0118] Additionally or alternatively, the DU component of the subnode may include multiple TRPs, which are shown as a first TRP of the DU component (e.g., a first DU-TRP, TRP1, or DU-TRP1) and a second TRP of the DU component (e.g., a second DU-TRP, TRP2, or DU-TRP2). In some aspects, the first DU-TRP may be used to communicate with the first subnode, and the second DU-TRP may be used to communicate with the second subnode. Alternatively, both the first DU-TRP and the second DU-TRP may be used to communicate with a single subnode (e.g., using multiple MIMO layers). Thus, different DU-TRPs of a subnode may communicate with different subnodes of the subnode or the same subnode of the subnode.

[0119] As shown in the reference numeral 905, the child node may determine the ability of the child node to communicate simultaneously. In example 900, the ability is the ability to communicate simultaneously with respect to multiple cells and / or multiple TRPs of the child node. For example, the ability can be the ability of the child node to use multiple cells and a single DU of the child node for simultaneous communication, the ability of the child node to use a single cell and multiple TRPs of the child node for simultaneous communication, the ability of the child node to use multiple cells and multiple TRPs of the child node (e.g., one TRP per cell, as shown) for simultaneous communication, etc. The ability to use multiple cells and / or multiple TRPs for simultaneous communication can be used for a single RAT, can be used for multiple RATs (e.g., a first RAT for a first cell and / or a first TRP, a second RAT for a second cell and / or a second TRP, etc.), and / or can be subject to conditional constraints, as described elsewhere herein.

[0120] As shown in reference numeral 910, the child node may send an indication of the ability of the child node to use multiple cells and / or multiple TRPs for simultaneous communication, as described above in conjunction with Figure 5 Description. For example, the capability indication may indicate whether the subnode supports simultaneous communication using multiple cells of the subnode DU (which are shown as DU-Cell1 and DU-Cell2). Additionally or alternatively, the capability indication may indicate whether the subnode supports simultaneous communication using multiple TRPs of a single cell for the subnode DU (which are shown as DU-TRP1-Cell1 and DU-TRP2-Cell1). Additionally or alternatively, the capability indication may indicate whether the subnode supports simultaneous communication using multiple TRPs of multiple cells for the subnode DU (which are shown as DU-TRP1-Cell1 and DU-TRP2-Cell2).

[0121] In the example described in conjunction with reference numeral 910, the capability indication for simultaneous communication is for both simultaneous transmission and simultaneous reception. In some aspects, the subnode may specifically indicate whether the capability indication is for simultaneous transmission, simultaneous reception, or both. For example, the capability indication may indicate whether the subnode supports simultaneous transmission using multiple cells of the subnode DU (e.g., DU-Cell1-TX and DU-Cell2-TX), may indicate whether the subnode supports simultaneous reception using multiple cells of the subnode DU (e.g., DU-Cell1-RX and DU-Cell2-RX), or may indicate whether the subnode supports simultaneous transmission and simultaneous reception using multiple cells of the subnode DU (e.g., DU-Cell1 and DU-Cell2, as shown in the figure). Additionally or alternatively, the capability indication may indicate whether the subnode supports simultaneous transmission of multiple TRPs using a single cell for the subnode DU (e.g., DU-TRP1-Cell1-TX and DU-TRP2-Cell1-TX), may indicate whether the subnode supports simultaneous reception of multiple TRPs using a single cell for the subnode DU (e.g., DU-TRP1-Cell1-RX and DU-TRP2-Cell1-RX), or may indicate whether the subnode supports simultaneous transmission and simultaneous reception of multiple TRPs using a single cell for the subnode DU (e.g., DU-TRP1-Cell1 and DU-TRP2-Cell1, as shown). Additionally or alternatively, the capability indication may indicate whether the subnode supports simultaneous transmission using multiple TRPs for multiple cells of the subnode DU (e.g., DU-TRP1-Cell1-TX and DU-TRP2-Cell2-TX), whether the subnode supports simultaneous reception using multiple TRPs for multiple cells of the subnode DU (e.g., DU-TRP1-Cell1-RX and DU-TRP2-Cell2-RX), or whether the subnode supports simultaneous communication using multiple TRPs for multiple cells of the subnode DU (e.g., DU-TRP1-Cell1 and DU-TRP2-Cell2, as shown).

[0122] In some aspects, the control node may use the default capabilities (e.g., capabilities that are not signaled) of the child node to configure the child node, schedule the child node, etc. The default capability may be that the child node supports simultaneous transmission and simultaneous 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 the child node supports simultaneous reception on a first cell and a second cell. In some aspects, unless the child node explicitly provides a capability indication indicating that the capability of the child node is different from the default capability, the control node may use the default capability.

[0123] In some aspects, a subnode may report only cell pairs or cell sets that do not support simultaneous communication, and a control node may use default capabilities for other cell pairs or cell sets. For example, for a subnode that supports three cells, a subnode may indicate that the subnode cannot use the first cell and the second cell for simultaneous communication. In this case, the control node may determine that the subnode can use the first cell and the third cell for simultaneous communication, and the control node can also use the second cell and the third cell for simultaneous communication. In some aspects, a subnode may indicate conditions associated with simultaneous communication, such as TDM requirements or conditions, which indicate that a cell set or cell pair and / or a TRP set or TRP pair cannot operate simultaneously.

[0124] In some aspects, the capability indication may be a bitmap, where each bit corresponds to a combination of simultaneous transmission and / or simultaneous 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 simultaneous reception for a combination of cells and / or TRPs. In some aspects, the capability indication may identify cells that a node can use for simultaneous communication.

[0125] In some aspects, the ability of a subnode to communicate simultaneously may be applied to both cells of the subnode, such as Fig. 9 As shown. Alternatively, the capability of the subnode for simultaneous communication may apply to more than two cells of the subnode. In this case, the subnode may report the simultaneous combined capability for multiple pairs of cells. Additionally or alternatively, the subnode may indicate the capability of using more than two cells for simultaneous communication. For example, the subnode may indicate that the subnode has the capability of simultaneously transmitting using a first cell of the subnode, simultaneously transmitting using a second cell of the subnode, and simultaneously receiving using a third cell of the subnode.

[0126] In some aspects, the child node may indicate the capability of all combinations of cells for simultaneous communication (e.g., all combinations of simultaneous transmission and simultaneous reception capabilities of all combinations of cells). Alternatively, the child node may indicate the capability of a subset of cells of the more than two cells for simultaneous communication. In some aspects, the subset may be a subset that includes only those combinations of cells with which the child node can communicate simultaneously (rather than any combination of TRPs with which the child node cannot communicate simultaneously). Alternatively, the subset may be a subset that includes only those combinations of cells with which the child node cannot communicate simultaneously (rather than any combination of TRPs with which the child node can communicate simultaneously). Additionally or alternatively, the subset may be indicated and / or requested in a report configuration.

[0127] As shown at 915, the child node may communicate with another node (eg, a control node, such as a parent node or a CU) in the IAB network based at least in part on the child node's ability to communicate simultaneously, as described above in conjunction with Figure 5 Description. For example, the control node may send a configuration to the child node based at least in part on the capability and / or may schedule resources for the child node (e.g., by sending a resource allocation to the child node). As an example, if the child node is capable of using multiple cells simultaneously for communication, the control node may schedule resources (e.g., time resources, frequency resources, or space resources, etc.) for the first cell of the child node, which are also scheduled for the second cell of the child node. In addition, the child node may send simultaneous communications in the scheduled resources. For example, the child node may use multiple cells of the child node for simultaneous communication (e.g., may communicate with one or more child nodes of the child node).

[0128] By enabling an IAB node to signal the ability of the IAB node to communicate with multiple cells simultaneously and thereafter use the multiple cells for simultaneous communication, some techniques and apparatus described herein may reduce latency, improve throughput, increase reliability, improve spectrum efficiency, etc. by utilizing simultaneous communication according to the capabilities of the IAB node. Additionally, by using the ability to configure the IAB node and / or schedule resources for the IAB node, configuration errors and / or resource scheduling conflicts may be reduced.

[0129] In some aspects, a child node may indicate the ability to simultaneously communicate with multiple parent nodes of the child node and multiple child nodes of the child node using multiple MT components of the child node, multiple TRPs of the child node, and / or multiple cells of the child node. Figure 6 , Figure 7 , Figure 8 and Fig. 9 The ability to communicate simultaneously with multiple parent nodes using multiple MT components, the ability to communicate simultaneously with multiple parent nodes and / or child nodes using multiple TRPs, the ability to communicate simultaneously with multiple MT components and using multiple TRPs (for example, each MT component may include one or more TRPs), the ability to communicate simultaneously with multiple cells and using multiple TRPs, or the ability to communicate simultaneously with multiple parent nodes using multiple MT components and using multiple TRPs, etc.

[0130] As indicated above, Fig. 9 are provided as examples. Other examples may differ from those described in Fig. 9 An example of description.

[0131] Fig.101 is a diagram illustrating an exemplary process 1000 performed, for example, by a node in a wireless network (e.g., a wireless multi-hop network, an IAB network, etc.) in accordance with various aspects of the present disclosure. Exemplary process 1000 is an example of a node (e.g., IAB node 410, UE 120, child node, etc.) performing operations associated with simultaneous communication capability signaling in an IAB network.

[0132] like Fig.10 As shown, in some aspects, process 1000 may include sending an indication of the ability of a node to communicate simultaneously with respect to at least one of: multiple parent nodes of the node, multiple mobile terminal components of the node, multiple transmit-receive points of the node, multiple cells of the node, or a combination thereof (block 1010). For example, the node (e.g., using transmit processor 220, transmit processor 264, controller / processor 240, controller / processor 280, memory 242, memory 282, etc.) may send an indication of the ability of the node to communicate simultaneously with respect to at least one of: multiple parent nodes of the node, multiple mobile terminal components of the node, multiple transmit-receive points of the node, multiple cells of the node, or a combination thereof, as described above.

[0133] like Fig.10 As further shown in FIG. 1 , in some aspects, process 1000 may include communicating with another node in the wireless network based at least in part on the capability (block 1020). For example, the node (e.g., using transmit processor 220, transmit processor 264, receive processor 238, receive processor 258, controller / processor 240, controller / processor 280, memory 242, memory 282, etc.) may communicate with another node in the wireless network based at least in part on the capability, as described above.

[0134] Process 1000 may include additional aspects, such as any single aspect or any combination of aspects described below and / or in combination with one or more other processes described elsewhere herein.

[0135] In a first aspect, the capabilities are for simultaneous communications using a single radio access technology.
