[0002] This Patent Application claims priority to U.S. Provisional Patent Application No. 62 / 706,858, filed September 14, 2020, entitled “PRIORITY-BASED RESOURCE PLANNING IN INTEGRATED ACCESS AND BACKHAUL RADIO ACCESS NETWORK SHARING,” and U.S. Non-Provisional Patent Application No. 17 / 447,523, filed September 13, 2021, entitled “PRIORITY-BASED RESOURCE PLANNING IN INTEGRATED ACCESS AND BACKHAUL RADIO ACCESS NETWORK SHARING,” which are expressly incorporated by reference herein. TECHNICAL FIELD

[0003] Aspects of the disclosure relate generally to wireless communication, and to techniques and apparatuses for priority-based resource planning in integrated access and backhaul radio access network sharing. BACKGROUND

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

[0005] A wireless network can include a number of base stations (BSs) that can support communication for a number of user equipment (UEs). A UE can communicate with a BS via the downlink and uplink. “Downlink” (or “forward link”) refers to the communication from the BS to the UE, and “uplink” (or “reverse link”) refers to the communication from the UE to the BS. As will be described in more detail herein, a BS can be referred to as a Node B, a gNB, an access point (AP), a radio head, a transmit receive point (TRP), a New Radio (NR) BS, a 5G Node B, and / or the like.

[0006] These multiple access technologies have been adopted in various telecommunication standards to provide common protocols that enable different wireless devices to communicate on a municipal, national, regional, and even global level. NR, which can also be referred to as 5G, is a set of enhancements to the LTE mobile standard promulgated by 3GPP. NR is designed to better support mobile broadband Internet access by improving spectral efficiency, lowering costs, improving services, making use of new spectrum, and better integrating with other open standards using orthogonal frequency division multiplexing (OFDM) with a cyclic prefix (CP) (CP-OFDM) on the downlink (DL) and using CP-OFDM and / or SC-FDM (e.g., also known as discrete Fourier transform spread ODFM (DFT-s-OFDM)) on the uplink (UL). NR supports beamforming, multiple input multiple output (MIMO) antenna technology, and carrier aggregation. These refinements in LTE and other radio access technologies (RATs) continue to help meet the growing demand for mobile data SUMMARY

[0007] In some aspects, a method of wireless communication performed by a network node includes transmitting, to a first integrated access and backhaul (IAB) donor central unit (CU), an indication of a first priority level associated with a first communication resource served by a distributed unit (DU) of the network node and a second priority level associated with a second communication resource served by the DU, wherein the first priority level is higher than the second priority level; and receiving, from the first IAB donor CU, a first resource configuration for the first communication resource based at least in part on the indication of the first priority level.

[0008] In some aspects, a network node for wireless communication includes a memory and one or more processors coupled to the memory, the memory and the one or more processors configured to: transmit, to a first IAB donor CU, an indication of a first priority level associated with a first communication resource served by a DU of the network node and a second priority level associated with a second communication resource served by the DU, wherein the first priority level is higher than the second priority level; and receive, from the first IAB donor CU, a first resource configuration for the first communication resource based at least in part on the indication of the first priority level.

[0009] In some aspects, a non-transitory computer-readable medium storing a set of instructions for wireless communication includes one or more instructions that, when executed by one or more processors of a network node, cause the network node to: send to a first IAB donor CU an indication of a first priority level associated with a first communication resource served by a DU of the network node and an indication of a second priority level associated with a second communication resource served by the DU, wherein the first priority level is higher than the second priority level; and receive from the first IAB donor CU a first resource configuration for the first communication resource, at least in part based on the indication of the first priority level.

[0010] In some aspects, an apparatus for wireless communication includes means for sending to a first IAB donor CU an indication of a first priority level associated with a first communication resource served by a distributed unit (DU) of the apparatus and an indication of a second priority level associated with a second communication resource served by the DU, wherein the first priority level is higher than the second priority level; and means for receiving from the first IAB donor CU a first resource configuration for the first communication resource based at least in part on the indication of the first priority level.

[0011] The aspects generally include methods, apparatus, systems, computer program products, non-transitory computer-readable media, user equipment, base stations, wireless communication equipment and / or processing systems as described herein with reference to the accompanying drawings and description.

[0025] Various aspects of the disclosure will be described more fully with reference to the accompanying drawings. The disclosure may, however, be embodied in many different forms and should not be construed as limited to any specific structure or function presented throughout this disclosure. Rather, these aspects are provided as illustrative examples so as to convey the scope of the disclosure to those skilled in the art. Based on the teachings provided herein, one skilled in the art should appreciate that the scope of the disclosure is intended to cover any aspect of the disclosure disclosed herein, whether implemented independently of or combined with any other aspect of the disclosure. For example, an apparatus can be implemented or a method can be practiced using any number of the aspects set forth herein. In addition, the scope of the disclosure is intended to cover such an apparatus or method which is practiced using, as alternative to, in combination with, or in addition to, any of the aspects of the disclosure set forth herein. It should be understood that any aspect of the disclosure disclosed herein can be embodied by one or more elements of a claim.

[0026] Several aspects of telecommunication systems will now be presented with reference to various apparatus and methods. These apparatus and methods will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements can be implemented using hardware, software, or combinations thereof. Whether such elements are implemented as hardware or software depends on the particular application and design constraints imposed on the overall system.

[0027] It should be noted that while aspects can be described herein using terminology commonly associated with a 5G or NR radio access technology (RAT), aspects of the present disclosure can be applied to other RATs, such as a 3G RAT, a 4G RAT, and / or a RAT subsequent to 5G (e.g., 6G).

[0028] Figure 1 is a diagram illustrating an example of a wireless network 100, in accordance with the present disclosure. Wireless network 100 can be or include elements of a 5G (NR) network and / or an LTE network, among other examples. Wireless network 100 can include a number of base stations 110 (shown as BS 110a, BS 110b, BS 110c, and BS 1 lOd) and other network entities. A base station (BS) is an entity that communicates with user equipment (UEs) and can also be referred to as an NR BS, a Node B, a gNB, a 5G node B (NB), an access point, a transmit receive point (TRP), and / or the like. Each BS can provide communication coverage for a particular geographic area. In 3GPP, the term“cell” can refer to a coverage area of a BS and / or a BS subsystem serving the coverage area, depending on the context in which the term is used.

[0029] BSs can be referred to as macro BS, small cell, femto cell, and / or the like. A macro cell can cover a relatively large geographic area (e.g., 5-10 miles in radius) and can allow unrestricted access by UEs with service subscriptions. A small cell can cover a relatively small geographic area and can allow restricted access by UEs such as UEs in a specific Figure 1 In an example shown in FIG. 1, BS 110a can be a macro BS for a macro cell 102a, BS 110b can be a small cell for a small cell 102b, and BS 110c can be a femto cell for a femto cell 102c. A BS can support one or multiple (e.g., three) cells. The terms“eNB,”“base station,”“NR BS,”“gNB,”“TRP,”“AP,”“Node B,”“5G NB,” and“cell” can be used interchangeably herein.

[0030] In some aspects, a cell can not necessarily be stationary, and the geographic area of the cell can move with a mobile BS. In some aspects, BSs can be interconnected to one another and / or to one or more other BSs or network nodes (not shown) in wireless network 100 through various types of backhaul interfaces such as a direct physical connection or a virtual network using any suitable transport network.

[0031] Wireless network 100 can also include relay stations. A relay station is an entity that can receive a transmission of data from an upstream station (e.g., a BS or a UE) and send a transmission of the data to a downstream station (e.g., a UE or a BS). A relay station can also be a UE that can relay transmissions for other UEs. Figure 1 In the example shown in Figure 1, a relay BS 1 lOd can communicate with macro BS 110a and a UE 120d in order to facilitate communications between BS 110a and UE 120d. A relay BS can also be referred to as a relay station, a relay base station, a relay, or the like.

[0032] Wireless network 100 can be a heterogeneous network that includes BSs of different types, such as macro BSs, pico BSs, femto BSs, relay BSs, or the like. These different types of BSs can have different transmit power levels, different coverage areas, and different impacts on interference. For example, macro BSs can have a high transmit power level (e.g., 5 to 40 watts) whereas pico BSs, femto BSs, and relay BSs can have relatively lower transmit power levels (e.g., 0.1 to 2 watts).

[0033] A network controller 130 can couple to a set of BSs and can provide coordination and control for these BSs. Network controller 130 can be

[0034] The UEs 120 (e.g., 120a, 120b, 120c) can be dispersed throughout the wireless network 100, and each UE can be stationary or mobile. A UE can also be referred to as an access terminal, a terminal, a mobile station, a subscriber unit, a station, etc. A UE can 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 equipment, a biometric sensor / device, a wearable device such as a smart watch, smart clothing, smart glasses, a smart wrist band, a smart jewelry (e.g., a smart ring, a smart bracelet), an entertainment device (e.g., a music or video device, or a satellite radio), a vehicular component or sensor, a smart meter / sensor, industrial manufacturing equipment, a global positioning system device, or any other suitable device that is configured to communicate via a wireless or wired medium.

[0035] Some UEs can be considered machine-type communication (MTC) or evolved or enhanced machine-type communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, and / or location tags, that can communicate with a base station, another device (e.g., remote device), or some other entity. A wireless node can provide, for example, connectivity for or to a network (e.g., a wide area network such as the Internet or a cellular network) via a wired or wireless communication link. Some UEs can be considered Intemet-of-Things (IoT) devices, and / or can be implemented as NB-IoT (narrowband

[0036] In general, any number of wireless networks can be deployed within a given geographic area. Each wireless network can support a particular RAT and can operate on one or more frequencies. A RAT can also be referred to as a radio technology, an air interface, etc. A frequency can also be referred to as a carrier, a frequency channel, etc. Each frequency can support a single RAT in a given geographic area in order to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks can be deployed.

[0037] In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) can communicate directly using one or more sidelink channels (e.g., without using base station 110 as an intermediary to communicate with each other). For example, UE s 120 can communicate using peer-to-peer (P2P) communications, device-to-device (D2D) communications, vehicle-to-everything (V2X) protocols (which can include vehicle-to- vehicle (V2V) protocols or vehicle-to-infrastructure (V2I) protocols), and / or netw ork d str ibuted (ND) communications. In this case, UE 120 can perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by base station 110.

[0038] Devices of wireless network 100 can use electromagnetic spectrum for communications, which can be subdivided, based on frequency or wavelength, into various classes, bands, channels, and / or the like. For example, devices of wireless network 100 can communicate using an operating band having a first frequency range (FR1), which can span from 410 MHz to 7.125 GHz, and / or can communicate using an operating band having a second frequency range (FR2), which can span from 24.25 GHz to 52.6 GHz. The frequencies between FR1 and FR2 are sometimes referred to as mid-band frequencies. Although a portion of FR1 is greater than 6 GHz, FR1 is often referred to as a “sub-6 GHz” band. Similarly, FR2 is often referred to as a “millimeter wave” band despite being different from the extremely high frequency (EHF) band, which the International Telecommunications Union (ITU) has identified as spanning from 30 GHz to 300 GHz. Thus, unless specifically stated otherwise, the term “sub-6 GHz” or the like can refer broadly to frequencies less than 6 GHz, frequencies within FR1, and / or mid-band frequencies (e.g., greater than 7.125 GHz). Similarly, unless specifically stated otherwise, the term “millimeter wave” or the like can refer broadly to frequencies within the EHF band, frequencies within FR2, and / or mid-band frequencies (e.g., less than 24.25 GHz). It is contemplated that the frequencies included in FR1 and FR2 can be modified, and that the techniques described herein apply to those modified frequency ranges.

[0039] As described above, Figure 1 are provided by way of example only. Other examples can differ from what is described. Figure 1 without limitation.

[0040] Figure 2is a diagram illustrating an example 200 of a base station 110 in communication with a UE 120 in a wireless network 100, in accordance with the present disclosure. Base station 110 can be equipped with T antennas 234a through 234t, and UE 120 can be equipped with R antennas 252a through 252r, where in general T > 1 and R > 1.

[0041] At base station 110, a transmit processor 220 can receive data from a data source 212 for one or more UEs, select one or more modulation and coding schemes (MCSs) for each UE based at least in part on channel quality indicators (CQIs) received from that UE, process (e.g., encode and modulate) the data for each UE based at least in part on the MCS(s) selected for the UE, and provide data symbols for all UEs. Transmit processor 220 can also process system information (e.g., semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper layer signaling) and provide overhead symbols and control symbols. Transmit processor 220 can also generate reference symbols for reference signals (e.g., a cell-specific reference signal (CRS) or a demodulation reference signal (DMRS)) and synchronization signals (e.g., a primary synchronization signal (PSS) or a secondary synchronization signal (SSS)). A transmit (TX) multiple-input multiple-output (MIMO) processor 230 can perform spatial processing (e.g., precoding) on the data symbols, the control symbols, the overhead symbols, and / or the reference symbols, if applicable, and can provide T output symbol streams to T modulators (MODs) 232a through 232t. Each modulator 232 can process a respective output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modulator 232 can further process (e.g., convert to analog, amplify, filter, and upconvert) the output sample stream to obtain a downlink signal. T downlink signals from modulators 232a through 232t can be transmitted via T antennas 234a through 234t, respectively.

[0042] At the UE 120, the antennas 252a through 252r can receive the downlink signals from the base station 110 and / or other base stations and can provide received signals to the demodulators (DEMODs) 254a through 254r, respectively. Each demodulator 254 can condition (e.g., filter, amplify, downconvert, and digitize) a received signal to obtain input samples. Each demodulator 254 can further process the input samples (e.g., for OFDM) to obtain received symbols. The MIMO detector 256 can obtain received symbols from all R demodulators 254a through 254r, perform MIMO detection on the received symbols if applicable, and provide detected symbols. The receive processor 258 can process (e.g., demodulate and decode) the detected symbols, provide decoded data for the UE 120 to a data sink 260, and provide decoded control information and system information to a controller / processor 280. The term “controller / processor” can refer to one or more controllers, one or more processors, or combinations thereof. A channel processor can determine reference signal received power (RSRP) parameters, receive signal strength indicator (RSSI) parameters, reference signal received quality (RSRQ) parameters, and / or CQI parameters, among other examples. In some aspects, one or more components of UE 120 can be included in a housing 284.

[0043] The network controller 130 can include a communication unit 294, a controller / processor 290, and a memory 292. The network controller 130 can include, for example, one or more devices in a core network. The network controller 130 can communicate with the base station 110 via the communication unit 294.

[0044] Antennas (e.g., antennas 234a through 234t and / or antennas 252a through 252r) can include or be included within one or more antenna panels, antenna groups, sets of antenna elements, and / or antenna arrays, among other examples. An antenna panel, antenna group, set of antenna elements, and / or antenna array can include one or more antenna elements. An antenna panel, antenna group, set of antenna elements, and / or antenna array can include a set of co-planar antenna elements and / or a set of non-co-planar antenna elements. An antenna panel, antenna group, set of antenna elements, and / or antenna array can include antenna elements within a single housing and / or antenna elements within multiple housings. An antenna panel, antenna group, set of antenna elements, and / or antenna array can include one or more antenna elements coupled to one or more transmit and / or receive components (such as one or more components of a transceiver 288). Figure 2 An antenna panel, antenna group, set of antenna elements, and / or antenna array can include one or more antenna elements coupled to one or more transmit and / or receive components (such as one or more components of a transceiver 288).

[0045] On the uplink, at UE 120, a transmit processor 264 can receive and process data from a data source 262 and control information (e.g., for reports comprising RSRP, RSSI, RSRQ, and / or CQI) from controller / processor 280. Transmit processor 264 can also generate reference symbols for one or more reference signals. The symbols from transmit processor 264 can be precoded by a TX MIMO processor 266 if applicable, further processed by modulators 254a through 254r (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to base station 110. In some aspects, a modulator and a demodulator (e.g., MOD / DEMOD 254) of the UE 120 can be included in a modem of the UE 120. In some aspects, the UE 120 includes a transceiver. The transceiver can include any combination of antenna(s) 252, modulators and / or demodulators 254, MIMO detector 256, receive processor 258, transmit processor 264, and / or TX MIMO processor 266. The transceiver can be used by a processor (e.g., controller / processor 280) and memory 282 to perform aspects of any of the methods described herein (for example, as described with reference to Figures 8-11 the description).

[0046] At base station 110, the uplink signals from UE 120 and other UEs can be received by antennas 234, processed by demodulators 232, detected by a MIMO detector 236 if applicable, and further processed by a receive processor 238 to obtain decoded data and control information sent by UE 120. Receive processor 238 can provide the decoded data to a data sink 239 and to controller / processor 240 for control information. Base station 110 can include communication unit 244 and communicate to network controller 130 via communication unit 244. Base station 110 can include a scheduler 246 to schedule UEs 120 for downlink and / or uplink communications. In some aspects, a modulator and a demodulator (e.g., MOD / DEMOD 232) of the base station 110 can be included in a modem of the base station 110. In some aspects, the base station 110 includes a transceiver. The transceiver can include any combination of antenna(s) 234, modulators and / or demodulators 232, MIMO detector 236, receive processor 238, transmit processor 220, and / or TX MIMO processor 230. The transceiver can be used by a processor (e.g., controller / processor 240) and memory 242 to perform aspects of any of the methods described herein (for example, as described with reference to Figures 8-11 the description).

[0047] Controller / processor 240 of base station 110, controller / processor 280 of UE 120, and / or Figure 2Any of the other components of Figure 2 may perform one or more techniques associated with priority-based resource planning in integrated access and backhaul (IAB) radio access network (RAN) sharing, as described in more detail elsewhere herein. For example, the controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or any other component of Figure 10 may perform or direct operations of, for example, the process 1000 of Figure 10 and / or other processes as described herein. The memories 242 and 282 can store data and program codes for the base station 110 and UE 120, respectively. In some aspects, the memory 242 and / or the memory 282 can include a non-transitory computer-readable medium storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, the one or more instructions, when executed by one or more processors of the base station 110 and / or the UE 120, can cause the one or more processors, the UE 120, and / or the base station 110 to perform or direct operations of, for example, the process 1000 of and / or other processes as described herein. In some aspects, executing instructions can include, among other examples, running the instructions, converting the instructions, compiling the instructions, and / or interpreting the instructions.

[0048] In some aspects, a network node (e.g., a base station 110, an IAB node, etc.) can include means for transmitting, to a first IAB donor central unit (CU), an indication of a first priority level associated with a first communication resource served by a distributed unit (DU) of the network node and a second priority level associated with a second communication resource served by the DU, where the first priority level is higher than the second priority level; means for receiving, from the first IAB donor CU, a first resource configuration for the first communication resource based at least in part on the indication of the first priority level; and / or the like. In some aspects, such means can include one or more components of the base station 110 described in connection with Figure 2 , such as the antenna 234, the DEMOD 232, the MIMO detector 236, the receive processor 238, the controller / processor 240, the transmit processor 220, the TX MIMO processor 230, the MOD 232, the antenna 234, and / or the like.

[0049] Although the blocks in Figure 2 are illustrated as distinct components, the functionality described above with respect to the blocks can be implemented in a single hardware, software, or combined component or in various combinations of components. For example, the functionality described with respect to the transmit processor 264, the receive processor 258, and / or the TX MIMO processor 266 can be performed by or under the control of the controller / processor 280.

[0050] As described above, Figure 2 are provided by way of example only. Other examples can differ from what is described. Figure 2 without limitation.

[0051] Figure 3 is a diagram illustrating an example 300 of a radio access network, in accordance with the present disclosure.

[0052] As shown in FIG. 3, a legacy (e.g., 3G, 4G, or LTE) radio access network can include a plurality of base stations 310 (e.g., access nodes (ANs)), where each base station 310 communicates with a core network via a wired backhaul link 315, such as a fiber connection. The base stations 310 can communicate with UEs 320 via access links 325, which can be wireless links. In some aspects, Figure 3 The base stations 310 shown in FIG. 3 can be the base stations 110 shown in FIG. 1. In some aspects, Figure 1 The UEs 320 shown in FIG. 3 can be the UEs 120 shown in FIG. 1. Figure 3 The UEs 320 shown in FIG. 3 can be the UEs 120 shown in FIG. 1. Figure 1 The UEs 320 shown in FIG. 3 can be the UEs 120 shown in FIG. 1.

[0053] As shown in FIG. 3, a radio access network can include a wireless backhaul network, sometimes referred to as an integrated access and backhaul (IAB) network. In an IAB network, at least one base station is an anchor base station 335, which communicates with a core network via a wired backhaul link 340, such as a fiber connection. The anchor base station 335 can also be referred to as an IAB donor (or IAB-donor). The IAB network can 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 stations 345 can 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 links 350 can be wireless links. The anchor base station 335 and / or the non-anchor base stations 345 can communicate with one or more UEs 355 via access links 360, which can be wireless links for carrying access traffic. In some aspects, Figure 3 The anchor base stations 335 and / or the non-anchor base stations 345 shown in FIG. 3 can be the base stations 110 shown in FIG. 1. In some aspects, Figure 1 The UEs 355 shown in FIG. 3 can be the UEs 120 shown in FIG. 1. Figure 3 The UEs 355 shown in FIG. 3 can be the UEs 120 shown in FIG. 1. Figure 1 The UEs 355 shown in FIG. 3 can be the UEs 120 shown in FIG. 1.

[0054] As indicated by reference numeral 365 in the accompanying drawings, in some aspects, radio access networks, including IAB networks, can utilize millimeter-wave technology and / or directional communication (e.g., beamforming) for communication between base stations and / or UEs (e.g., between two base stations, between two UEs, and / or between a base station and a UE). For example, a radio backhaul link 370 between base stations can use millimeter-wave signals to carry information and / or can be beamformed toward a target base station. Similarly, a radio access link 375 between a UE and a base station can use millimeter-wave signals and / or can be beamformed toward a target radio node (e.g., between a UE and / or a base station). In this way, inter-link interference can be reduced.

[0055] Figure 3 The configuration of the base station and UE in the example is shown, and other examples can be envisioned. For example, Figure 3 The one or more base stations shown can be replaced by one or more UEs communicating via a UE-to-UE access network (e.g., a peer-to-peer network or a device-to-device network). In this case, the anchor node can refer to a UE that communicates directly with a base station (e.g., an anchor base station or a non-anchor base station).

[0056] As mentioned above, Figure 3 This is provided as an example only. Other examples may differ from those provided. Figure 3 The content described.

[0057] Figure 4 This is a diagram illustrating an example 400 of an IAB network architecture according to the present disclosure.

[0058] 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 (e.g., the user plane interface between an NG-RAN node and user plane functions) may terminate at the core network. Alternatively or additionally, the IAB donor 405 may connect to one or more devices of the core network that provide core access and mobility management functions (e.g., AMF). In some aspects, the IAB donor 405 may include a base station 110, such as an anchor base station, as described above. Figure 3The. As shown, the IAB donor 405 can include a central unit (CU) that can perform access node controller (ANC) functions and / or AMF functions. The CU can configure distributed units (DUs) of the IAB donor 405 and / or can configure one or more IAB nodes 410 connected to the core network via the IAB donor 405 (e.g., MTs and / or DUs of the IAB nodes 410). Thus, the CU of the IAB donor 405 can control and / or configure an entire IAB network connected to the core network via the IAB donor 405, such as by using control messages and / or configuration messages (e.g., radio resource control (RRC) configuration messages or Fl application protocol (Fl-AP) messages, etc.). The IAB nodes can act as layer 2 relays of traffic transmitted via the CU-configured or -managed IAB network.

[0059] The CU (whether associated with an IAB donor or a gNB) can perform RRC layer functions and packet data convergence protocol (PDCP) functions. The DU can act as a scheduling node that schedules child nodes of the network node with which the DU is associated. For example, the DU can perform radio link control (RLC), medium access control (MAC), and physical (PHY) layer functions.

[0060] As further shown in Figure 4 As further shown in

[0061] When a first node controls and / or schedules communications of a second node (e.g., when the first node provides a DU functionality for an MT functionality of the second node), the first node can be referred to as a parent node of the second node, and the second node can be referred to as a child node of the first node. A child node of a second node can be referred to as a grandchild node of a first node. Thus, a DU functionality of a parent node can control and / or schedule communications of a child node of the parent node. The parent node can be an IAB donor 405 or an IAB node 410, and the child node can be an IAB node 410 or a UE 120. Communications of an MT functionality of the child node can be controlled and / or scheduled by a parent node of the child node.

[0062] As further shown in Figure 4 a link between a UE 120 (e.g., having only an MT functionality and no DU functionality) and an IAB donor 405, or between a UE 120 and an IAB node 410, can be referred to as an access link 415. The access link 415 can be a wireless access link that provides radio access to a core network to the UE 120 via the IAB donor 405 and, optionally, via one or more IAB nodes 410. Thus, Figure 4 a network as shown in

[0063] As further shown in Figure 4 a link between an IAB donor 405 and an IAB node 410, or between two IAB nodes 410, can be referred to as a backhaul link 420. The backhaul link 420 can be a wireless backhaul link that provides radio access to a core network to the IAB node 410 via the IAB donor 405 and, optionally, via one or more other IAB nodes 410. In an IAB network, network resources (e.g., time resources, frequency resources, and / or spatial resources) for wireless communications can be shared between the access links 415 and the backhaul links 420. In some aspects, the backhaul link 420 can be a primary backhaul link or a secondary backhaul link (e.g., a backup backhaul link). In some aspects, the secondary backhaul link can be used if, among other examples, the primary backhaul link fails, becomes congested, and / or becomes overloaded. For example, if the primary backhaul link between IAB node 2 and IAB node 1 fails, the backup link 425 between IAB node 2 and IAB node 3 can be used for backhaul communications. As used herein, a node or wireless node can refer to an IAB donor 405 or an IAB node 410.

[0064] As described above, Figure 4 are provided by way of example only. Other examples can differ from what is described. Figure 4

[0065] Figure 5 ​is a diagram illustrating an example 500 of resource types in an IAB network according to the present disclosure.

[0066] In an IAB network, time domain resources (sometimes referred to as time resources) can be configured as downlink only, uplink only, flexible, or unavailable (e.g., NA, not available). For example, time domain resources can be configured via a DU cell resource configuration, such as a gNB-DU cell resource configuration, as described in connection with Figure 6 In more detail, when a time resource is configured as downlink only for a wireless node, the time resource can be used only for downlink communications, and not uplink communications, of the wireless node. Similarly, when a time resource is configured as uplink only for a wireless node, the time resource can be used only for uplink communications, and not downlink communications, of the wireless node. When a time resource is configured as flexible for a wireless node, the time resource can be used for both downlink and uplink communications of the wireless node. When a time resource is configured as unavailable for a wireless node, the time resource is unavailable for any communications of the wireless node.

[0067] Examples of downlink communications include synchronization signal blocks (SSBs) (both cell-defining SSBs (CD-SSBs) and non-CD-SSBs), channel state information reference signals (CSI-RSs), physical downlink control channel (PDCCH) communications, physical downlink shared channel (PDSCH) communications, and the like. Examples of uplink communications include physical random access channel (PRACH) communications, physical uplink control channel (PUCCH) communications, physical uplink shared channel (PUSCH) communications, sounding reference signals (SRSs), and the like.

[0068] Time resources in an IAB network that are configured as downlink only, uplink only, or flexible can be 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 communications of the wireless node. For example, a hard downlink only time resource is always available only for downlink communications of the wireless node, a hard uplink only time resource is always available only for uplink communications of the wireless node, and a hard flexible time resource is always available for uplink and downlink communications of the wireless node.

[0069] When a time resource is configured as a soft resource for a wireless node, the availability of the time resource is controlled by a parent node of the wireless node. For example, the parent node can indicate (e.g., explicitly or implicitly) whether a soft time resource is available for communications of the wireless node. Thus, a soft time resource can be in one of two states: a schedulable state (e.g., when the soft time resource is available for scheduling and / or communications of the wireless node) and a non-schedulable state (e.g., when the soft time resource is not available for scheduling and / or communications of the wireless node).

[0070] For example, when a parent node of a wireless node indicates that a soft downlink only time resource is available, the soft downlink only time resource is only available for downlink communications by the wireless node. Similarly, when a parent node of a wireless node indicates that a soft uplink only time resource is available, the soft uplink only time resource is only available for uplink communications by the wireless node. When a parent node of a wireless node indicates that a soft flexible time resource is available, the soft flexible time resource is only available for uplink and downlink communications by the wireless node.

[0071] As an example, and as shown by reference number 505, a time resource can be configured to be hard for a child node, and the time resource can be configured to be unavailable for a parent node of the child node. In this case, the parent node cannot use the time resource for communications, but the child node can schedule communications in the time resource and / or use the time resource for communications. This configuration can reduce interference between the parent node and the child node, can reduce scheduling conflicts between the parent node and the child node, and / or the like.

[0072] As another example, and as shown by reference number 510, a time resource can be configured to be unavailable for a child node, and can be configured to be hard, soft, or unavailable for a parent node (e.g., depending on network configuration, network conditions, configuration of a parent node of the parent node, and / or the like). In this case, the child node cannot schedule communications in the time resource, and cannot use the time resource for communications.

[0073] As another example, and as shown by reference number 515, a time resource can be configured to be soft for a child node, and can be configured to be hard, soft, or unavailable for a parent node (e.g., depending on network configuration, network conditions, configuration of a parent node of the parent node, and / or the like). In this case, the child node cannot use the time resource to schedule or communicate, unless the child node receives an indication (e.g., a release indication) from the parent node (e.g., explicitly or implicitly) that the time resource is available (i.e., released) for use by the child node. If the child node receives such an indication, the child node can schedule communications in the time resource and / or use the time resource for communications.

[0074] As described above, Figure 5 are provided by way of example only. Other examples are possible and can differ from those described. Figure 5 as described.

[0075] Figure 6is a diagram illustrating an example 600 of DU cell resource configuration for IAB, according to the present disclosure. The example 600 includes an IAB donor CU. The IAB donor CU can be associated with a gNB. The IAB donor CU can handle resource configuration for parent DUs and IAB nodes. Thus, the IAB donor CU can accommodate half-duplex constraints of parent DUs, IAB nodes, and / or other nodes of an IAB network.

[0076] The IAB donor CU can provide resource configuration via cell resource configuration (shown as “gNB-DU cell resource configuration”). In some aspects, as shown by reference number 605, the cell resource configuration can be specific to a cell. For example, the IAB donor CU can provide a respective cell resource configuration for each cell served by a DU. The cell resource configuration can indicate, among other things, Figure 5

[0077] The term “cell” can refer to a logical communication entity for communication (e.g., by a carrier) with a base station and can be associated with an identifier used to distinguish neighboring cells operating via a same or different carrier. In some examples, a cell can support different services and / or device types (e.g., machine type communication (MTC), narrowband Internet of Things (NB-IoT), enhanced mobile broadband (eMBB), ultra-reliable low-latency (URLLC) communication, etc.). In some cases, the term “cell” can refer to a portion of a geographic coverage area (e.g., a sector) over which a logical entity operates. If a DU handles scheduling for communication via a cell, the cell can be referred to as being “served” by the DU.

[0078] A cell can have a cell global identifier (CGI), such as an NR CGI (NCGI). The NCGI uniquely identifies a cell. The NCGI includes a public land mobile network (PLMN) identifier and an NR cell identifier. The PLMN identifier (which can include 24 bits) can include an MCC (e.g., 12 bits) and an MNC (e.g., 12 bits). The NCI (e.g., 36 bits in 5G) can include a gNB identifier (e.g., the leftmost 22 to 32 bits) and a local cell identifier (e.g., the remaining bits of the NCI). The gNB can be unique within a gNB and can be common to all cells (e.g., all IAB donor DUs and all IAB node DUs) served by a gNB with one IAB donor CU. Equivalently, the PLMN and gNB ID can globally identify a gNB.

[0079] As described above, Figure 6 is provided by way of example only. Other examples are possible and can differ from Figure 6 what is described.

[0080] ​Figure 7 is a diagram illustrating an example 700 of radio access network (RAN) sharing for IAB, in accordance with the present disclosure.

[0081] As Figure 7 shown, in a RAN sharing scenario, there can be two donor CUs: an IAB donor CU1 (referred to as CU1) and an IAB donor CU2 (referred to as CU2). CU1 and CU2 can be associated with an enhanced gNB that supports IAB functionality. In some cases, as Figure 7 shown, CU1 and CU2 can manage shared communication resources associated with IAB nodes. The communication resources can be used to serve one or more child nodes (e.g., UE1) associated with a first DU (referred to as DU1) of a parent DU, one or more child nodes (e.g., UE2) associated with a second DU (referred to as DU2) of the parent DU, and / or the like.

[0082] As Figure 7 shown, an IAB node can receive resource configurations for serving communication resources from CU1 and CU2. In some cases, a parent node and a child node can apply configurations from a CU for non-orthogonal resources to handle multiplexing constraints. However, in some cases, a parent node can apply configurations received from one CU and a child node can apply configurations received from another CU. In this case, the application of the two configurations can result in a failure to satisfy multiplexing constraints.

[0083] For example, as shown by reference number 720, a first resource configuration of resources at a first time (shown as time 1) and at a second time (shown as time 2) can have different availability than a second resource configuration of resources at time 1 and time 2. As shown, for example, the first resource configuration can be received from CU1 (indicated by CU1) and the second resource configuration can be received from CU2 (indicated by CU2). The top row of configuration information can be associated with a parent node (e.g., a parent DU) and the bottom row can be associated with a child node (e.g., an IAB node).

[0084] At time 1, if both the parent node and the child node apply the first resource configuration (CU1), the resource is shown as hard downlink (shown as “H-DL”) for the parent node, which means the resource is available for downlink. At time 1, under the first resource configuration, the resource is indicated as not available (shown as “NA”) for the child node. Thus, if both the child node and the parent node apply the first resource configuration, there is no conflict. However, if the parent node applies the first resource configuration and the child node applies the second resource configuration (indicated by CU2), the resource is indicated as hard downlink for both the parent node and the child node. If both the child node and the parent node use the resource at time 1, the communications can interfere with each other. Such interference can reduce throughput, cause radio link failure, and require active interference mitigation, consuming network resources and negatively impacting network performance.

[0085] Additionally, the child node can apply the first resource configuration at time 2, and the parent node can apply the second resource configuration at time 2. In this case, at time 2, the resource is indicated as not available for both the parent node and the child node. Thus, the resource can not be used, introducing inefficiency in resource allocation, which can negatively impact network performance.

[0086] Some techniques and apparatuses described herein provide signaling that enables an IAB donor CU to treat priority levels as an additional dimension in resource planning. By selecting a resource configuration based at least in part on a priority level associated with traffic, some techniques and apparatuses described herein can help provide resource configurations that can reduce interference, improve communication efficiency, and improve network resource utilization, positively impacting network performance.

[0087] As described above, Figure 7 are provided by way of example only. Other examples can differ from what is described. Figure 7 without departing from the spirit of the disclosure.

[0088] Figure 8 is a diagram illustrating an example 800 of signaling associated with resource configuration for IAB ARAN sharing, in accordance with the present disclosure. As shown, the example 800 includes a network node 805, a first CU 810 (e.g., an IAB donor CU), and a second CU 815 (e.g., a second IAB donor CU). The network node 805 can include, for example, an IAB node (e.g., similar to the IAB node 105). Figure 7 The first CU 810 can include an IAB donor CU (e.g., similar to the IAB donor CU1 110). Figure 7 The second CU 815 can include an IAB donor CU (e.g., similar to the IAB donor CU2 115). Figure 7the IAB donor CU 2). The network node 805 can communicate with the first CU 810 and / or the second CU 815 using a signaling connection. The signaling connection can be associated with at least one of an Fl control protocol or a radio resource control (RRC) control.

[0089] The first CU 810 can be associated with a first network and the second CU 815 can be associated with a second network. The first CU 810 can be associated with resource management for a first IAB topology and the second CU 815 can be associated with resource management for a second IAB topology that overlaps with the first IAB topology. The network node 805 can provide one or more cells based at least in part on one or more resource configurations provided by the first CU 810 and / or the second CU 815.

[0090] As shown by reference number 820, the network node 805 can transmit and the first CU 810 can receive an indication of a first communication resource and a second communication resource. The first communication resource and the second communication resource can be served by a DU of the network node 805. The first communication resource and / or the second communication resource can include a cell, a frequency resource, a time resource, a spatial region, or a combination thereof, served by the network node 805. As shown by reference number 825, the network node 805 can transmit and the first CU 810 can receive an indication of a first priority level associated with the first communication resource and a second priority level associated with the second communication resource. In some aspects, the first priority level can be higher than the second priority level.

[0091] As shown by reference number 830, the network node 805 can transmit and the second CU 815 can receive an indication of the first communication resource and a third priority level associated with the first communication resource. The third priority level can be different than the first priority level. In some aspects, the network node 805 can transmit and the first CU 810 can receive an indication that the network node 805 transmitted the indication of the first communication resource and / or the third priority level associated with the first communication resource to the second CU 815.

[0092] In some aspects, the network node 805 can select at least one of the first priority level, the second priority level, or the third priority level based at least in part on at least one of the associated communication resource, the CU to which the associated resource is reported, the CU to which at least one of the first priority level, the second priority level, or the third priority level is reported, a network identifier associated with the CU to which the associated resource is reported, a network identifier associated with the CU to which at least one of the first priority level, the second priority level, or the third priority level is reported, or a combination thereof.

[0093] As shown by reference number 835, the first CU 810 can transmit and the network node 805 can receive an indication of a first resource configuration for the first communication resource. As shown, the first CU 810 can also transmit an indication of a second resource configuration for the second communication resource. In some aspects, the first CU 810 can transmit the first resource configuration based at least in part on the indication of the first priority level. The first resource configuration and / or the second resource configuration can indicate availability of the communication resource (e.g., available, unavailable, conditionally available), direction of the resource (e.g., downlink, uplink, flexible), and / or the like.

[0094] In some aspects, the network node 805 can determine whether to apply the second resource configuration. For example, the network node 805 can refrain from applying the second resource configuration based at least in part on determining that the first priority level is higher than the second priority level. In this way, resources can be prioritized for higher priority traffic. In some aspects, the network node 805 can apply the second resource configuration based at least in part on determining that a condition is satisfied, even if the second priority level can be lower than the first priority level. For example, as described in connection with Figure 9 As described, the network node 805 can determine that there is no traffic at the parent DU associated with the communication resource. The network node 805 can apply the second resource configuration to utilize the communication resource that would otherwise not be used. Accordingly, some aspects can facilitate more efficient use of resources, positively impacting network performance.

[0095] As shown by reference number 840, the second CU 815 can transmit and the network node 805 can receive an indication of a third resource configuration for the first communication resource. As shown by reference number 845, the network node 805 can apply one of the first resource configuration, the second resource configuration, or the third resource configuration based at least in part on determining which of the first priority level, the second priority level, and the third priority level is the highest level. In some aspects, an initial priority level associated with a particular type of traffic can be configured on the network node 805. The initial priority level can be configured, for example, by an operations, administration, and maintenance module.

[0096] In some aspects, for example, the network node 805 can determine that the first priority level is higher than the third priority level, and can apply the first resource configuration based at least in part on determining that the first priority level is higher than the third priority level. The first resource configuration can indicate that the first communication resource is available, and the third resource configuration can indicate that the first communication resource is unavailable. Accordingly, in this case, the network node 805 can use the first communication resource.

[0097] In some aspects, the network node 805 can use the first communication resources for uplink, where the first resource configuration indicates that the first communication resources are usable for uplink, and the third resource configuration indicates that the first communication resources are usable for downlink. In some aspects, the network node 805 can determine that the third priority level is higher than the first priority level, and can apply the third resource configuration based at least in part on determining that the third priority level is higher than the first priority level.

[0098] The network node 805 can determine that the first priority level is higher than the third priority level, and can communicate traffic corresponding to the first CU 810 or a network associated with the first CU 810 using the first communication resources based at least in part on determining that the first priority level is higher than the third priority level. The network node 805 can be, for example, a child node associated with the first CU 810 or a child node associated with a network associated with the first CU 810.

[0099] In some aspects, the network node 805 can determine that the third priority level is higher than the first priority level, and can communicate traffic corresponding to the second CU 815 or a network associated with the second CU 815 using the first communication resources based at least in part on determining that the third priority level is higher than the first priority level. The network node 805 can determine that the first priority level is higher than the third priority level, determine that there is no traffic associated with the first communication resources and corresponding to the first CU 810 or a network associated with the first CU 810, and apply the third resource configuration to the first communication resources based at least in part on determining that there is no traffic associated with the first communication resources.

[0100] In some aspects, the network node 805 can determine that the first priority level is higher than the third priority level, that there is no traffic associated with the first communication resources and corresponding to the first CU 810 or a network associated with the first CU 810, and communicate traffic corresponding to the second CU 815 or a network associated with the second CU 815 using the first communication resources based at least in part on determining that there is no traffic associated with the first communication resources. In some aspects, a first set of traffic associated with the first CU 810 can have a first associated traffic priority level, and a second set of traffic associated with the second CU 815 can have a second associated traffic priority level. The network node 805 can determine that the first priority level is higher than the third priority level, determine that the second traffic priority level is higher than the first traffic priority level, and communicate the second set of traffic using the first communication resources based at least in part on determining that the second traffic priority level is higher than the first traffic priority level. In some aspects, the second set of traffic can include ultra-reliable low-latency communication traffic.

[0101] As described above, Figure 8are provided by way of example only. Other examples can differ from what is described Figure 8 The described content. According to some examples, the first CU 810, the second CU 815, and / or another device can request a particular priority level from the network node 805. The network node 805 can provide the requested priority level, such as if one or more conditions are met.

[0102] Figure 9 is a diagram illustrating an example 900 of using priority levels associated with resource configurations shared with IAB ARAN, in accordance with the present disclosure. Aspects of the example 900 can be implemented by a network node (e.g., the network node 805 shown in Figure 8 FIG. 1), a first CU (e.g., the first CU 810 shown in Figure 8 FIG. 1), a second CU (e.g., the second CU 815 shown in Figure 8 FIG. 1), and / or the like.

[0103] As shown, a set of resources configured for high priority traffic of a first CU and / or a network associated with the first CU (CU1 / PLMN1 / NPN1) can be configured for a cell served by a first parent node DU1 and a first child node DU1 using a first resource configuration. Similarly, a set of resources configured for high priority traffic of a second CU and / or a network associated with the second CU (CU2 / PLMN2 / NPN2) can be configured for a cell served by a second parent node DU2 and a second child node DU2 using a second resource configuration. As shown, in a first example, if there is no traffic associated with CU1 / PLMN1 / NPN1, a hard resource configured for high priority resources of CU1 / PLMN1 / NPN1 can be used by parent DU2 for traffic associated with CU2 / PLMN2 / NPN2. As shown, in a second example, if there is no traffic associated with CU1 / PLMN1 / NPN1 and a soft resource configured for high priority resources of CU1 / PLMN1 / NPN1 is released by a parent node of child DU2, the resource can be used by child DU2 for traffic associated with CU2 / PLMN2 / NPN2.

[0104] Different variations can apply to the use of high priority resources configured for CU1 / PLMN1 / NPN1 when there is no traffic associated with CU1 / PLMN1 / NPN1. In a first variation, the resources can be used to carry traffic associated with CU2 / PLMN2 / NPN2 after the resource configuration of CU1. In a second variation, the resources can be used to carry traffic associated with CU2 / PLMN2 / NPN2 after the resource configuration of CU2.

[0105] Any number of various scenarios can be implemented in connection with assigning priority levels to traffic and allowing unused resources from other resource configurations to be used. As a result, some aspects can increase network reliability and efficiency, which positively impacts network performance.

[0106] As described above, Figure 9 are provided by way of example only. Other examples can differ from what is described Figure 9 in connection with what is described.

[0107] Figure 10 is a diagram illustrating an example process 1000 performed, for example, by a network node, in accordance with the present disclosure.
