TECHNICAL FIELD

[0003] Aspects of the present disclosure relate generally to wireless communication, and more specifically to techniques and apparatuses for identification and utilization of assisting nodes. 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 communication from the BS to the UE, and “uplink” (or “reverse link”) refers to 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] The above multiple access technologies have been adopted in various telecommunication standards to provide common protocol that enables different wireless devices to communicate on the same frequency. 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 OFDM with a cyclic prefix (CP) (CP-OFDM) on the downlink (DL), using CP- OFDM and / or SC-FDM (e.g., also known as discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-s-OFDM)) on the uplink (UL), as well as supporting beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation. However, as the demand for mobile broadband access continues to increase, there exists a need for further improvements in LTE, NR, and other radio access technologies. SUMMARY

[0045] Various aspects of the disclosure are described more fully below. However, the disclosure may be implemented in any of numerous ways, 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 that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. The scope of the disclosure is intended to cover any aspect of the disclosure disclosed herein, whether implemented independently of or in combination 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 apparatus or method which

[0046] 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.

[0047] 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).

[0048] Figure 1is a diagram illustrating an example of a wireless network 100 in accordance with the present disclosure. The wireless network 100 can be or can include elements of a 5G (NR) network and / or a LTE network, among other examples. The 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 NodeB, 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.

[0049] BSs can be macro BSs, pico BSs, femto BSs, and / or other types of BSs. A macro BS can cover a relatively large geographic area (e.g., 100s of feet to 10s of kilometers in radius) and can allow unrestricted access to users with service subscriptions. A pico BS can cover a relatively small geographic area (e.g., a home) and can allow restricted access to users with service subscriptions. A femto BS can cover a relatively small geographic area (e.g., a home) and can allow restricted access to users with service subscriptions. Figure 1 In the example shown in FIG. 1, the BSs 110a can be macro BSs for the macro cells 102a, the BS 1 lOb can be a pico BS for the pico cell 102b, and the BS 1 lOc can be a femto BS for the 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.

[0050] In some aspects, a cell can not necessarily be stationary, and the geographic area of the cell can move according to the location of a mobile BS. In some aspects, the BSs can be interconnected to one another and / or to one or more other BSs or network nodes (not shown) in the wireless network 100 through various types of backhaul interfaces (such as a direct physical connection or a virtual network, using any suitable transmission medium) using any suitable transmission network.

[0051] 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 FIG. 1, relay BS 1 lOd can communicate with macro BS 110a and UE 120d in furtherance of communication 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.

[0052] 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 lower transmit power levels (e.g., 0.1 to 2 Watts).

[0053] A network controller 130 can couple to a set of BSs and can provide coordination and control for these BSs. Network controller 130 can communicate with the BSs via a backhaul. The BSs can also communicate with one another directly or indirectly via a wireless or wireline backhaul.

[0054] UEs 120 (e.g., 120a, 120b, 120c) can be dispersed throughout 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, medical equipment or devices, biometric sensors / devices, wearable devices (smart watches, smart clothing, smart glasses, smart wrist bands, smart jewelry (e.g., smart rings, smart bracelets)), 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.

[0055] 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 Internet-of-Things (IoT) UEs, and / or can be implemented as NB-IoT (narrowband

[0056] In general, any number of wireless networks can be deployed in 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, and / or the like. Frequencies can also be referred to as carriers, frequency channels, and / or the like. 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.

[0057] 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 one another). For example, UE 120 can perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by base station 110. Some communications between UEs 120 can be referred to as “vehicle-to- everything” (V2X) communications. For example, V2X communications can include

[0058] Devices of wireless network 100 can communicate using the electromagnetic spectrum, which can be subdivided by frequency or wavelength into various classes, bands, channels, and so on. 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 (30 GHz - 300 GHz) identified by the International Telecommunications Union (ITU) as a “millimeter wave” band. Thus, unless specifically stated otherwise, it will be understood that the term “sub-6 GHz” or the like means frequencies less than 6 GHz, frequencies within FR1, and / or mid-band frequencies (e.g., greater than 7.125 GHz), as applicable. Similarly, unless specifically stated otherwise, it will be understood that, where “millimeter wave” or the like is used, this term means frequencies within FR2, frequencies within the EHF band (e.g., less than 24.25 GHz), and / or mid-band frequencies (e.g., greater than 52.6 GHz), as applicable. It is contemplated that the frequencies included in FR1 and FR2 can be modified, and thus the techniques described herein are applicable to those modified frequency ranges.

[0059] As indicated above, Figure 1 are provided as examples. Other examples can differ from what is described with respect to at least one of the following. Figure 1

[0060] Figure 2 is a diagram illustrating an example 200 in which a base station 110 is in communication with a UE 120 in a wireless network 100, in accordance with the present disclosure. The base station 110 can be equipped with T antennas 234a through 234t, and the UE 120 can be equipped with R antennas 252a through 252r, where in general T > 1 and R > 1.

[0061] ​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 the 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., for semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper layer signaling) and provide overhead symbols and control symbols. 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.

[0062] 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. A 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. A 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, received 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.

[0063] 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.

[0064] Antennas (e.g., antennas 234a through 234t and / or antennas 252a through 252r) can include or be included in one or more antenna panels, antenna groups, antenna element sets, and / or antenna arrays, among other examples. An antenna panel, antenna group, antenna element set, and / or antenna array can include one or more antenna elements.

[0065] 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.

[0074] Although Figure 2 The blocks in FIG. 13 are illustrated as distinct components, but the functionality described above in relation to these blocks can be implemented in a single hardware, software, or combined component or a combination of various components.

[0075] As indicated above, Figure 2 are provided by way of example. Other examples can differ from what is described Figure 2 without departing from the spirit of the disclosure.

[0076] Figure 3 is a diagram illustrating an example 300 of a radio access network, in accordance with the present disclosure.

[0077] As shown by reference number 305, a legacy (e.g., 3G, 4G, LTE, etc.) 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.

[0078] As shown by reference number 330, a radio access network can include a wireless backhaul network, sometimes referred to as an 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 link(s) 350 can be wireless links. The anchor base station(s) 335 or the non-anchor base station(s) 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 station 335 and / or the non-anchor base station 345 shown in FIG. 3 can be the base station 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.

[0079] As shown by reference number 365, in some aspects, a radio access network including an IAB network can utilize millimeter wave technology and / or directional communications (e.g., beamforming, etc.) for communications between base stations and / or UEs (e.g., between two base stations, between two UEs, and / or between a base station and a UE). For example, a wireless backhaul link 370 between base stations can use millimeter wave signals to carry information and / or can be directed to a target base station using beamforming, etc. Similarly, a wireless access link 375 between a UE and a base station can use millimeter wave signals and / or can be directed to a target wireless node (e.g., a UE and / or a base station). In this way, inter-link interference can be reduced.

[0080] Figure 3 The configuration of the base stations and UEs in FIG. 4 is shown as an example and other examples are contemplated. For example, Figure 3 One or more of the base stations illustrated in FIG. 4 can be replaced with one or more UEs that communicate via a UE-to-UE access network (e.g., a peer-to-peer network, a device-to-device network, etc.). In this case, an “anchor node” can refer to a UE that communicates directly with a base station (e.g., an anchor base station or a non-anchor base station).

[0081] As indicated above, Figure 3 is provided as an example. Other examples can differ from what is described with respect to FIG. 4. Figure 3 is provided as an example. Other examples can differ from what is described with respect to FIG. 4.

[0082] Figure 4 is a diagram illustrating an example 400 of an IAB network architecture, in accordance with the present disclosure.

[0083] As shown in FIG. 4, Figure 4 The IAB network can include an IAB donor 405 (shown as an IAB donor) that connects to a core network via a wired connection (shown as a wired backhaul). For example, an Ng interface of the IAB donor 405 can terminate at the core network. Additionally, or alternatively, the IAB donor 405 can connect to one or more devices of the core network that provide a core access and mobility management function (e.g., an AMF). In some aspects, the IAB donor 405 can include a base station 110, such as described above in connection with FIG. 1. Figure 3The described anchor base station. As shown, the IAB donor 405 can include a central unit (CU) that can perform access node controller (ANC) functions, AMF functions, and / or the like. The CU can configure a distributed unit (DU) of the IAB donor 405 and / or can configure one or more IAB nodes 410 (e.g., a mobile termination (MT) unit and / or a DU of an IAB node 410) connected to the core network via the IAB donor 405. Thus, the CU of the IAB donor 405 can control and / or configure the entire IAB network connected to the core network via the IAB donor 405, such as by using control messages and / or configuration messages (e.g., radio resource control (RRC) configuration messages, Fl application protocol (Fl-AP) messages, and / or the like).

[0084] As further shown in Figure 4 the IAB network can include IAB nodes 405 (shown as IAB node 1, IAB node 2, and IAB node 3) connected to the core network via an IAB donor 410. As shown, an IAB node 410 can include MT functions (sometimes also referred to as UE functions (UEF)) and can include DU functions (sometimes also referred to as access node functions (ANF)). The MT functions of an IAB node 410 (e.g., a child node) can be controlled and / or scheduled by another IAB node 410 (e.g., a parent node of the child node) and / or by the IAB donor 405. The DU functions of an IAB node 410 (e.g., a parent node) can control and / or schedule other IAB nodes 410 (e.g., child nodes of the parent node) and / or UEs 120. Thus, a DU can be referred to as a scheduling node or scheduling component, and an MT can be referred to as a scheduled node or scheduled component. In some aspects, the IAB donor 405 can include DU functions without including MT functions. That is, the IAB donor 405 can configure, control, and / or schedule communications of the IAB nodes 410 and / or UEs 120. A UE 120 can include only MT functions without including DU functions. That is, communications of the UE 120 can be controlled and / or scheduled by the IAB donor 405 and / or an IAB node 410 (e.g., a parent node of the UE 120).

[0085] When a first node controls and / or schedules communications for a second node (e.g., when the first node provides DU functions for MT functions 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, the DU functions of a parent node can control and / or schedule communications for child nodes 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 the MT functions of a child node can be controlled and / or scheduled by a parent node of the child node.

[0086] As Figure 4 As further illustrated in FIG. 4, a link between a UE 120 (e.g., with only MT functionality and no DU functionality) and the 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 The network illustrated in FIG. 4 can be referred to as a multi-hop network or a wireless multi-hop network.

[0087] As Figure 4 As further illustrated in FIG. 4, a link between a UE 120 (e.g., with only MT functionality and no DU functionality) and the 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,

[0088] In some aspects, an IAB node 410 (e.g., a parent node) can not be able to communicate with another IAB node 410 (e.g., a child node) using a direct access link. For example, IAB node 2 can be outside of a communication range of IAB node 1 (e.g., IAB node 3), the direct access link between IAB node 1 and IAB node 2 can be blocked, and / or the like. IAB node 1 can utilize a remote unit (RU) node 425 (e.g., an assisting node, a relay node, a repeater node, and / or a reflector node, among other examples) to communicate with IAB node 2. IAB node 1 (e.g., a DU of IAB node 1) can communicate with RU node 425 using a front-haul link 430. For example, IAB node 1 can transmit a communication to RU node 425 using front-haul link 430. RU node 425 can forward the communication to IAB node 2 using access link 415 between IAB node 2 and RU node 425. In this way, IAB node 1 can extend a coverage area of IAB node 1 and communicate with IAB node 2 when IAB node 1 is not able to directly communicate using a direct access link between IAB node 1 and IAB node 2.

[0089] As described above, Figure 4 are provided by way of example. Other examples can differ Figure 4 from the described examples.

[0090] Figure 5 FIG. 1 illustrates an example 100 of a wireless communication system that supports forwarding communications between a first wireless node and a second wireless node, in accordance with some aspects of the present disclosure. As shown, example 100 includes a first wireless node 105 (e.g., an IAB node, an IAB donor, a base station 110, or a UE 120, among other examples), a second wireless node 115 (e.g., an IAB node, an IAB donor, a base station 110, or a UE 120, among other examples), and an assisting node 110 (e.g., a repeater device, a relay device, a reflector device, a reflective intelligent surface (RIS), an intelligent reflecting surface (IRS), or an RU, among other examples). In example 100, first wireless node 105 and / or second wireless node 115 can know assisting node 110. In some aspects, first wireless node 105 and / or second wireless node 115 can not know assisting node 110.

[0091] In some aspects, assisting node 510 can be a non-configurable assisting node 510. For example, assisting node 510 can be pre-configured with one or more parameters for forwarding communications. In some aspects, non-configurable assisting node 510 can be able to determine or reconfigure one or more parameters based at least in part on forwarding one or more communications. For example, non-configurable assisting node 510 can be able to autonomously adjust one or more pre-configured parameters for forwarding communications based at least in part on forwarding one or more communications.

[0092] In some aspects, the secondary node 510 can be a configurable secondary node 510. For example, the secondary node 510 can be configured by a controlling node (e.g., a CU of an IAB donor, a DU of an IAB node, or a base station, etc.). The secondary node 510 can communicate with the controlling node using a control interface. The controlling node can indicate one or more parameters for forwarding communications, one or more wireless nodes (e.g., the first wireless node 505 and the second wireless node 515, as shown) with which the secondary node 510 is to communicate, or one or more resource allocations for the secondary node 510, etc. The one or more parameters for forwarding communications can include a transmit power setting or configuration, a transmit beam configuration, a receive beam configuration, a forwarding communication direction (e.g., uplink or downlink), a reflection coefficient, or a reflection direction or angle, etc. Figure 5

[0093] As shown in FIG. 5, the first wireless node 505 can attempt to transmit a communication 520 (e.g., a data communication, a control communication, etc.) to the second wireless node 515 using a direct link 525 (e.g., an access link or a sidelink) between the first wireless node 505 and the second wireless node 515. However, the first wireless node 505 can not be able to transmit the communication 520 to the second wireless node 515 using the direct link 525. For example, the second wireless node 515 can be outside of a transmission range of the first wireless node 505, or the direct link 525 can be blocked, etc. In some aspects, the first wireless node 505 can not be able to transmit the communication 520 to the second wireless node 515 using the direct link 525 due to a direction of the communication 520. For example, a regulatory agency can limit a direction (e.g., an angle) that the first wireless node 505 is allowed to transmit (e.g., the regulatory agency can indicate that the first wireless node 505 cannot transmit at an upward angle, etc.). Figure 5

[0094] In some aspects, the first wireless node 505 can utilize the secondary node 510 to transmit the communication 520 to the second wireless node 515 to utilize an alternative communication path (e.g., different from the direct link 525) to the second wireless node 515. For example, the direct link 525 can be associated with poor reliability or can be limited due to a maximum permissible exposure (MPE) limit. The alternative communication path to the second wireless node 515 (e.g., an indirect link 530 through the secondary node 510) can provide increased reliability, provide increased spatial diversity, allow for higher order MIMO operation, allow for full duplex communication, and / or can enable the first wireless node 505 to transmit the communication 520 to the second wireless node 515 when use of the direct link 525 is limited (such as due to an MPE limit), etc.

[0095] ​​Accordingly, the first wireless node 505 can communicate with the second wireless node 515 using the indirect link 530. For example, the first wireless node 505 can transmit a communication 520 to the assisting node 510. In some aspects, the first wireless node 505 can transmit the communication 520 directly to the assisting node 510 (e.g., when the first wireless node 505 knows the assisting node 510). In some aspects, the assisting node 510 can be configured (e.g., by a control node or by the second wireless node 515) to receive the communication 520 from the first wireless node 505 (e.g., when the first wireless node 505 does not know the assisting node 510).

[0096] As shown, the communication 520 can pass to the assisting node 510 and be forwarded by the assisting node 510. For example, the assisting node 510 can receive the communication 520 and can repeat the communication 520 (e.g., can receive the communication 520, perform analog processing of the communication 520, apply a beamforming gain to the communication 520, and transmit the communication 520 to the second wireless node 515). In some aspects, the assisting node 510 can receive the communication 520 and can reflect the communication 520 to the second wireless node 515. Figure 5

[0097] In some cases, the indirect link 530 can be an access link, a sidelink, or a fronthaul link. For example, if the first wireless node 505 is a base station 110 and the second wireless node 515 is a UE 120, the indirect link 530 between the first wireless node 505 and the assisting node 510 can be a fronthaul link. The indirect link 530 between the assisting node 510 and the second wireless node 515 can be an access link. Using the communication scheme shown can improve network performance and increase reliability by providing the first wireless node 505 and / or the second wireless node 515 with link diversity for communication, or by extending a communication coverage area of the first wireless node 505 and / or the second wireless node 515, among other examples. Figure 5

[0098] ​​As described above, in some cases a wireless node (e.g., the first wireless node 505 and / or the second wireless node 515) can not be aware of the assistance node 510 (e.g., the assistance node 510 can be transparently deployed in the wireless network such that wireless nodes within the wireless network are not aware of the presence of the assistance node 510). In some cases, the wireless node can not be aware of the assistance node 510 prior to the assistance node 510 initiating establishment of a communication link (e.g., a communication interface such as a control interface) between the wireless node and the assistance node 510. For example, the assistance node 510 can initiate initial establishment of a communication interface between the wireless node and the assistance node 510 (e.g., in a manner similar to an initial access procedure performed between a UE and a base station). However, the wireless node can not be aware of the assistance node 510 prior to the assistance node 510 initiating initial establishment of the communication interface between the wireless node and the assistance node 510. Further, when the assistance node 510 is transparently deployed in the wireless network (e.g., when the assistance node 510 is an unconfigurable assistance node), the wireless node can never become aware of the assistance node 510. Thus, the wireless node can not be able to identify the assistance node 510 and can not be able to determine when and / or how to utilize the assistance node 510 to assist communications transmitted and / or received by the wireless node.

[0099] Some techniques and apparatuses described herein can efficiently identify and utilize assistance nodes. For example, a wireless node can receive identification information of one or more assistance nodes deployed within a wireless network. The identification information of an assistance node can include an identifier associated with the assistance node, location information associated with the assistance node, capability information associated with the assistance node, a receive direction associated with the assistance node, or a forwarding direction associated with the assistance node, among other examples. In some aspects, the wireless node can transmit an indication of the identification information of one or more assistance nodes acquired by the wireless node to another wireless node.

[0100] In some aspects, a wireless node can determine one or more relevant assistance nodes (e.g., assistance nodes located within a coverage area associated with the wireless node) and can transmit an indication of the one or more relevant nodes (e.g., and associated identification information) to one or more other wireless nodes. In some aspects, a wireless node can transmit an indication of one or more assistance nodes assigned to the wireless node (e.g., assistance nodes used by the wireless node and / or assistance nodes dedicated to the wireless node) to one or more other wireless nodes.

[0101] A wireless node (and / or another wireless node attempting to initiate a communication link with it) may receive an auxiliary node (and associated identification information) and an indication of the resources the wireless node will use for initial access with the auxiliary node (e.g., for establishing a communication link). This enables the wireless node and other wireless nodes attempting to initiate a communication link with it to utilize the auxiliary node and associated resources to perform initial access procedures to establish a communication link using the auxiliary node.

[0102] Therefore, wireless nodes can utilize auxiliary nodes to transmit or receive communication with other wireless nodes. In some aspects, wireless nodes can use the identification information associated with auxiliary nodes for interference management, beam management, power control, resource allocation, scheduling, mobility and handover procedures, or location, etc. Thus, wireless nodes can make better decisions about how or when to utilize auxiliary nodes for communication. Furthermore, the availability of identification information of auxiliary nodes within a wireless network can at least partially improve communication efficiency.

[0103] As mentioned above, Figure 5 Provided as an example. Other examples may be related to... Figure 5 The descriptions are different.

[0104] Figure 6 This is a diagram illustrating example 600 associated with the identification of auxiliary nodes according to this disclosure. (See diagram 600 for example.) Figure 6 As shown, the first wireless node 605, the second wireless node 610, and the third wireless node 615 can communicate with each other in a wireless network (e.g., wireless network 100). In some aspects, the first wireless node 605 can be a control node or an intermediate wireless node, such as base station 110, the CU of an IAB donor, the DU of an IAB node, a parent IAB node, UE 120, a roadside unit (RSU), a core network device, or an operation, management, and maintenance (OAM) module, etc. In some aspects, the second wireless node 610 and / or the third wireless node 615 can be the CU of an IAB donor, the DU of an IAB node, the MT component of an IAB node, UE 120, or base station 110, etc.

[0105] As shown by reference numeral 620 in the accompanying drawings, the second wireless node 610 can transmit and the first wireless node 605 can receive requests for available auxiliary nodes (e.g., repeater nodes, reflector nodes, configurable auxiliary nodes, and / or non-configurable auxiliary nodes) deployed in the wireless network. A request for an available auxiliary node may be a request for identification information associated with the auxiliary node (e.g., information that enables the second wireless node 610 to identify, locate, and / or utilize the auxiliary node).

[0106] As shown by reference number 625, the first wireless node 605 can transmit and the second wireless node 610 can receive an indication of one or more available assisting nodes deployed in the wireless network. The indication can include identification information for each of the one or more assisting nodes. For example, the first wireless node 605 can transmit a list of one or more available assisting nodes deployed in the wireless network. For each assisting node included in the list, the list can indicate identification information associated with the assisting node.

[0107] In some aspects, the identification information for an assisting node can include identification information and / or configuration information associated with the assisting node. For example, the identification information for an assisting node can include an identifier associated with the assisting node (e.g., a unique identifier associated with the assisting node and / or an index value associated with the assisting node), location information associated with the assisting node, a type associated with the assisting node (e.g., whether the assisting node is a repeater device, a reflector device, a configurable assisting node, or a non-configurable assisting node, etc.), capability information associated with the assisting node, a receive direction (or angle) associated with the assisting node, or a forward (or reflect) direction (or angle) associated with the assisting node, etc.

The capability information associated with an assisting node can include one or more current configurations of the assisting node and / or one or more allowed configurations of the assisting node. For example, the capability information associated with an assisting node can indicate one or more parameters used by the assisting node for forwarding communications, such as a transmit power setting or configuration, a transmit beam configuration, a receive beam configuration, a forward communication direction (e.g., uplink or downlink), a reflection coefficient, or a reflection direction or angle, etc.

[0109] In some aspects, the first wireless node 605 can transmit the indication of one or more available assisting nodes deployed in the wireless network via an interface between the first wireless node 605 and the second wireless node 610. For example, the interface can be an OAM interface, an Fl application protocol (Fl-AP) interface, a direct link interface (e.g., a Uu interface) or a sidelink interface (e.g., a PC5 interface), etc.

[0110] For example, the first wireless node 605 can be an OAM module, and the OAM module can transmit an indication of one or more available secondary nodes deployed in a wireless network to the second wireless node 610, which can be a CU of an IAB donor, a DU of an IAB node, an IAB node, or a UE 120, among other examples.

In some aspects, the first wireless node 605 can be a CU of an IAB donor, and the CU can transmit an indication of one or more available secondary nodes deployed in a wireless network to the second wireless node 610, which can be a DU of an IAB node (e.g., where the indication is transmitted via an Fl-AP interface), an MT component of an IAB node, or a UE 120.

[0111] In some aspects, the first wireless node 605 can be a DU of a parent IAB node, and the DU can transmit an indication of one or more available secondary nodes deployed in a wireless network to the second wireless node 610, which can be an MT component of a child IAB node (e.g., where the indication is transmitted via a Uu interface), among other examples. In some aspects, the first wireless node 605 can be a DU of an IAB node, and the DU can transmit an indication of one or more available secondary nodes deployed in a wireless network to the second wireless node 610, which can be a UE 120, among other examples. In some aspects, the first wireless node 605 can be a UE 120 or RSU, and the UE 120 or RSU can transmit an indication of one or more available secondary nodes deployed in a wireless network to the second wireless node 610, which can be a UE 120 (e.g., where the indication is transmitted via a PC5 interface), among other examples.

[0112] In some aspects, the first wireless node 605 can transmit the indication of one or more available secondary nodes deployed in a wireless network via a RRC message (e.g., when the first wireless node 605 is a CU or a base station 110, among other examples). In some aspects, the first wireless node 605 can transmit the indication of one or more available secondary nodes deployed in a wireless network via a medium access control (MAC) control element (MAC-CE) message (e.g., when the first wireless node 605 is a DU, among other examples). While the above examples have been described with respect to an indication of one or more available secondary nodes, the above examples can apply to other communications between the first wireless node 605 and the second wireless node 610 (or the first wireless node 605 and the third wireless node 615) described herein.

[0113] As shown by reference number 630, the second wireless node 610 can transmit, to one or more other wireless nodes (e.g., the first wireless node 605, the second wireless node 610, and / or other wireless nodes), an indication of the identification information of one or more assisting nodes that has been acquired (e.g., received and / or determined) by the second wireless node 610. For example, the second wireless node 610 can receive, such as from the first wireless node 605 as described above, an indication of one or more wireless nodes and associated identification information. In some aspects, the second wireless node 610 can determine the identification information associated with an assisting node based at least in part on a communication with the assisting node. In some aspects, a child node of the second wireless node 610 or a node served by the second wireless node 610 can detect an assisting node. The child node and / or the served node can transmit, to the second wireless node 610, an indication of the assisting node (e.g., and associated identification information). The second wireless node 610 can compile and / or store a list of assisting nodes (e.g., and associated identification information). In some aspects, the second wireless node 610 can transmit, to another wireless node, an indication of the identification information of one or more assisting nodes that has been acquired by the second wireless node 610 based at least in part on receiving a request from the other wireless node for the identification information associated with the assisting nodes.

[0114] In some aspects, the second wireless node 610 can be a CU, and the CU can transmit, to another CU, a core network device, and / or an OAM module, and / or the like, an indication of the identification information of one or more assisting nodes that has been acquired by the CU. In some aspects, the second wireless node 610 can be a DU, and the DU can transmit, to a CU and / or an OAM module, and / or the like, an indication of the identification information of one or more assisting nodes that has been acquired by the DU. In some aspects, the second wireless node 610 can be an IAB node, and the IAB node can transmit, to a parent node of the IAB node, a CU, and / or a core network device, and / or the like, an indication of the identification information of one or more assisting nodes that has been acquired by the IAB node. In some aspects, the second wireless node 610 can be a UE 120, and the UE 120 can transmit, to a DU, a CU, a core network device, an OAM module, another UE 120, and / or a RSU, and / or the like, an indication of the identification information of one or more assisting nodes that has been acquired by the UE 120.

[0115] In some aspects, the second wireless node 610 can broadcast an indication of the identification information of the one or more assisting nodes that have been acquired by the second wireless node 610. For example, the second wireless node 610 can broadcast an indication of the identification information of the one or more assisting nodes that have been acquired by the second wireless node 610 in a system information block (SIB) (e.g., when the second wireless node 610 is a DU, etc.). In some aspects, the second wireless node 610 can broadcast an indication of the identification information of the one or more assisting nodes that have been acquired by the second wireless node 610 over a sidelink channel (e.g., when the second wireless node 610 is a UE 120, etc.).

[0116] As shown by reference number 635, the second wireless node 610 can determine one or more relevant assisting nodes. For example, the second wireless node 610 can determine one or more assisting nodes that are within a coverage area associated with the second wireless node 610. Thus, the one or more relevant assisting nodes can be used or can be able to assist in communications with the second wireless node 610. In some aspects, the second wireless node 610 can determine the one or more relevant assisting nodes based at least in part on the identification information of the one or more assisting nodes that have been acquired by the second wireless node 610.

[0117] As shown by reference number 640, the second wireless node 610 can transmit an indication of the identification information of the one or more relevant assisting nodes to one or more other wireless nodes (e.g., the first wireless node 605, the second wireless node 610, and / or other wireless nodes). In some aspects, the second wireless node 610 can transmit the indication of the identification information of the one or more relevant assisting nodes based at least in part on receiving a request for an indication of relevant assisting nodes associated with the second wireless node 610. In some aspects, the second wireless node 610 can transmit the indication of the identification information of the one or more relevant assisting nodes to a wireless node that transmitted the request. In some aspects, the second wireless node 610 can transmit the indication of the identification information of the one or more relevant assisting nodes to a different wireless node than the wireless node that transmitted the request (e.g., the first wireless node 605 can request that the second wireless node 610 transmit the indication of the identification information of the one or more relevant assisting nodes to the third wireless node 615).

[0118] The second wireless node 610 can transmit the indication of the identification information of the one or more relevant assisting nodes in a similar manner as described above with respect to reference number 630. In some aspects, the second wireless node 610 can broadcast (e.g., in a SIB or over a sidelink channel) the indication of the identification information of the one or more relevant assisting nodes.

[0119] As shown in FIG. 6, the first wireless node 605 can receive an indication of identification information of one or more related assisting nodes associated with the second wireless node 610 and can transmit, to the third wireless node 615, the indication of the identification information of the one or more related assisting nodes associated with the second wireless node 610. This can enable the second wireless node 610 to establish a communication connection with the second wireless node 610 using an assisting node of the one or more related assisting nodes.

[0120] As shown in FIG. 6, the second wireless node 610 can transmit, and the first wireless node 605 can receive, a request for one or more assisting nodes (e.g., and associated identification information) to be assigned to the second wireless node 610 (e.g., available for use by the second wireless node 610 and / or dedicated to the second wireless node 610). As shown in FIG. 6, the first wireless node 605 can transmit, and the second wireless node 610 can receive, an indication of the one or more assisting nodes assigned to the second wireless node 610. For example, the first wireless node 605 can be a controlling node. The first wireless node 605 can determine the one or more assisting nodes to be assigned to the second wireless node 610. The first wireless node 605 can transmit, to the second wireless node 610 and / or one or more other wireless nodes, an indication of the one or more assisting nodes (e.g., and associated identification information) assigned to the second wireless node 610.

[0121] As shown in FIG. 6, in some aspects, the second wireless node 610 can determine the one or more assisting nodes assigned to the second wireless node 610. In some aspects, the second wireless node 610 can determine the one or more assisting nodes assigned to the second wireless node 610 based at least in part on an indication received from a controlling node, such as from the first wireless node 605 as described above. In some aspects, the second wireless node 610 can autonomously determine the one or more assisting nodes assigned to the second wireless node 610.

[0122] As shown in FIG. 6, the second wireless node 610 can transmit, to one or more other wireless nodes (e.g., the first wireless node 605, the third wireless node 615, and / or other wireless nodes), an indication of the one or more assisting nodes (e.g., and associated identification information) assigned to the second wireless node 610. The other wireless nodes can utilize the indication of the one or more assisting nodes assigned to the second wireless node 610 to communicate with the second wireless node 610 to determine which assisting nodes deployed in the wireless network are available (e.g., unassigned) for beam management purposes or for signal interference management purposes, among other examples.

[0123] In some aspects, the second wireless node 610 can transmit an indication of one or more secondary nodes assigned to the second wireless node 610 (e.g., and associated identification information) based at least in part on receiving a request for an indication of secondary nodes assigned to the second wireless node 610. In some aspects, the second wireless node 610 can transmit the indication of one or more secondary nodes assigned to the second wireless node 610 to a wireless node that transmitted the request. In some aspects, the second wireless node 610 can transmit the indication of one or more secondary nodes assigned to the second wireless node 610 to a different wireless node than the wireless node that transmitted the request (e.g., the first wireless node 605 can request that the second wireless node 610 transmit the indication of one or more secondary nodes assigned to the second wireless node 610 to the third wireless node 615).

[0124] As described above, the first wireless node 605 can receive an indication of one or more secondary nodes assigned to the second wireless node 610 and / or can determine one or more secondary nodes assigned to the second wireless node 610. As shown by reference number 670, the first wireless node 605 can transmit and the third wireless node 615 can receive an indication of one or more secondary nodes assigned to the second wireless node 610 (e.g., and associated identification information). The third wireless node 615 can utilize the one or more secondary nodes assigned to the second wireless node 610 to communicate with the second wireless node 610. For example, the third wireless node 615 can establish a communication connection with the second wireless node using a secondary node of the one or more secondary nodes assigned to the second wireless node 610. The third wireless node 615 can transmit a link establishment request to the second wireless node 610 via a secondary node of the one or more secondary nodes assigned to the second wireless node 610.

[0125] In some aspects, the third wireless node 615 can utilize the one or more secondary nodes assigned to the second wireless node 610 to determine one or more available secondary nodes for use by the third wireless node 615. In some aspects, the third wireless node 615 can utilize the one or more secondary nodes assigned to the second wireless node 610 to perform an interference and / or beam management procedure. For example, the third wireless node 615 can perform an interference and / or beam management procedure based at least in part on identification information associated with a secondary node assigned to the second wireless node 610.

[0126] In some aspects, the third wireless node 615 can utilize one or more secondary nodes assigned to the second wireless node 610 for a handover procedure. For example, the third wireless node 615 can determine that one or more child nodes associated with the third wireless node 615 are to be handed over to the second wireless node 610. The third wireless node 615 can transmit, to the second wireless node 610 via a secondary node of the one or more secondary nodes assigned to the second wireless node 610, a message initiating a handover procedure with the second wireless node 610.

[0127] In some aspects, the identification information of a secondary node can be associated with conditional information that restricts the identification information. For example, the conditional information can include a time interval associated with using the secondary node for communication, a periodic time interval associated with using the secondary node for communication, a transmission direction of the secondary node, a reception direction of the secondary node, one or more allowed configurations of the secondary node (e.g., a transmit power configuration, and / or the like), a frequency band associated with the secondary node, one or more resource blocks (RBs) associated with the secondary node, a communication direction associated with the secondary node (e.g., uplink only, downlink only, or both uplink and downlink), a reference signal resource allocation associated with the secondary node, a reference signal configuration associated with the secondary node, a transmission timing reference associated with the secondary node, or a numerology associated with the secondary node (e.g., a subcarrier spacing used by the secondary node or a cyclic prefix used by the secondary node), and / or the like.

[0128] For example, the conditional information of an assigned secondary node can indicate an amount of time (or a periodic amount of time) that the assigned secondary node is assigned to a wireless node. In some aspects, the conditional information of a secondary node can indicate available and / or unavailable frequency domain resources (e.g., frequency bands and / or RBs) and / or time domain resources associated with the secondary node. A wireless node (e.g., the first wireless node 605, the second wireless node 610, and / or the third wireless node 615) can use the conditional information of a secondary node to make a determination to use the secondary node for communication. For example, the wireless node can determine a transmission configuration to use when using the secondary node for communication, a numerology to use when using the secondary node for communication, and / or a transmission timing reference to use when using the secondary node for communication, and / or the like.

[0129] Thus, wireless nodes within a wireless network can be enabled to identify secondary nodes deployed within the wireless network. As such, the wireless nodes can make improved determinations associated with using secondary nodes deployed within the wireless network for communication. This can improve communication efficiency within the wireless network by enabling the wireless nodes to better utilize secondary nodes deployed within the wireless network.

[0130] As described above, Figure 6 Provided by way of example. Other examples can be provided.Figure 6 The descriptions are different.

[0131] Figure 7 This is a diagram illustrating example 700 related to the utilization of auxiliary nodes according to this disclosure. (See diagram 700.) Figure 7 As shown, control node 705, first wireless node 710, auxiliary node 715, and second wireless node 720 can communicate with each other in a wireless network (e.g., wireless network 100). In some aspects, control node 705 can be base station 110, CU of an IAB donor, DU of an IAB node, IAB node, OAM module, RSU, or first wireless node 605, etc. In some aspects, first wireless node 710 can be base station 110, UE 120, IAB donor, IAB node, CU, DU, UE 120, RSU, second wireless node 610, or third wireless node 615, etc. In some aspects, auxiliary node 715 can be a repeater device, remote unit of an IAB node, relay device, reflector device, or auxiliary node 710, etc. In some aspects, second wireless node 720 can be base station 110, UE 120, IAB donor, IAB node, CU, DU, UE 120, RSU, second wireless node 610, or third wireless node 615, etc. In some respects, the auxiliary node 715 can communicate with multiple first wireless nodes 710. In some respects, the auxiliary node 715 can communicate with multiple second wireless nodes 720.

[0132] As described above, the first wireless node 710 and the second wireless node 720 can communicate with each other using the auxiliary node 715. In some aspects, the first wireless node 710 and / or the second wireless node 720 can utilize identification information associated with the auxiliary node 715 (such as the identification information mentioned above). Figure 6 (Described identification information) to perform interference management, beam management, power control, resource allocation, scheduling, mobility determination, handover procedures and / or location, etc.

[0133] As indicated by reference numeral 725 in the accompanying drawings, control node 705 may transmit instructions for an auxiliary node (e.g., auxiliary node 715) for use by first wireless node 710 and second wireless node 720 in communication between the first wireless node 710 and second wireless node 720 (e.g., for establishing a communication connection). In some aspects, control node 705 may transmit instructions for resources (e.g., time-domain resources, frequency-domain resources, and / or spatial-domain resources) to be used for establishing a communication connection between the first wireless node 710 and second wireless node 720 using auxiliary node 715. For example, resources may indicate one or more resources for the first wireless node 710 to use for transmitting communication to auxiliary node 715 (e.g., communication to be forwarded by auxiliary node 715 to second wireless node 720) and / or one or more resources for the first wireless node 710 to use for receiving communication from auxiliary node 715 (e.g., communication already forwarded by auxiliary node 715 from second wireless node 720). Similarly, resources may indicate one or more resources that the second wireless node 720 will use to transmit communications to the auxiliary node 715 and / or one or more resources that the second wireless node 720 will use to receive communications from the auxiliary node 715.

[0134] In some aspects, the indication of the auxiliary node 715 and / or associated resources can indicate identification information associated with the auxiliary node 715. In some aspects, the first wireless node 710 and / or the second wireless node 720 can determine or receive the indication of identification information associated with the auxiliary node 715, as described above regarding... Figure 6 As described.

[0135] In some aspects, such as Figure 7 As shown, control node 705 can transmit instructions for auxiliary node 715 and / or associated resources to both the first wireless node 710 and the second wireless node 720. In some aspects, control node 705 can transmit instructions for auxiliary node 715 and / or associated resources to only one of the first wireless node 710 and the second wireless node 720.

[0136] As indicated by reference numeral 730 in the accompanying drawings, the first wireless node 710 may transmit indications of one or more auxiliary nodes (e.g., including auxiliary node 715) and associated resources currently used by the first wireless node 710 for the initial access procedure (e.g., a random access channel (RACH) procedure) with the first wireless node 710. In some aspects, the first wireless node 710 may broadcast indications of one or more auxiliary nodes (e.g., including auxiliary node 715) and associated resources currently used by the first wireless node 710 for the initial access procedure.

[0137] For example, in some aspects, the first wireless node 710 and / or the second wireless node 720 can be caused to establish a communication connection using the assisting node 715 without the control node 705. That is, the first wireless node 710 can determine one or more resources and / or an assisting node (e.g., the assisting node 715) to use to perform an initial access procedure with the first wireless node 710. As described above, the first wireless node 710 can transmit (e.g., broadcast) an indication of the one or more resources and / or the assisting node (e.g., the assisting node 715) to use to perform the initial access procedure with the first wireless node 710. In this way, the second wireless node 720 can be enabled to identify the assisting node 715 and / or the one or more resources, and can establish a communication connection with the first wireless node 710 using the one or more resources and the assisting node 715 (e.g., without needing to receive an indication of the assisting node 715 and / or the one or more resources from the control node 705).

[0138] In some aspects, the indication of the assisting node 715 and / or the associated resources (e.g., transmitted by the control node 705 or the first wireless node 710, as described above) can be transmitted using upper layer signaling or lower layer signaling. In some aspects, the indication of the assisting node 715 and / or the associated resources can be transmitted using different interfaces, such as an Fl-AP interface, a Uu interface, or a PC5 interface, among other examples. In some aspects, the indication of the assisting node 715 and / or the associated resources can be transmitted in an RRC message or a MAC-CE message, among other examples.

[0139] In some aspects, the indication of the assisting node 715 and / or the associated resources (e.g., transmitted by the control node 705 or the first wireless node 710, as described above) can indicate one or more periodic signals associated with the initial access procedure that the first wireless node 710 is transmitting (e.g., and the resources used by the first wireless node 710 to transmit the one or more periodic signals) and / or one or more resources monitored by the first wireless node 710 for signals associated with the initial access procedure.

[0140] In some aspects, the indication of the secondary node 715 and / or associated resources (e.g., transmitted by the controlling node 705 or the first wireless node 710, as described above) can indicate one or more beams to be used for communicating using the secondary node 715. In some aspects, the one or more beams can be indicated using different spatial references. The different spatial references can be used for non-reciprocal beam pairs, such as a quasi co-location (QCL) reference or a transmission configuration indicator (TCI) state used by the first wireless node 710 or the second wireless node 720 for beams used to communicate using the secondary node 715. For example, a QCL reference can be used to indicate one or more beams that the first wireless node 710 can use to transmit signals to or receive signals from the secondary node 715. Similarly, a QCL reference can be used to indicate one or more beams that the second wireless node 720 can use to transmit signals to or receive signals from the secondary node 715. The controlling node 705 can transmit one or more QCL references to the first wireless node 710 and / or the second wireless node 720 to indicate beams that can be used to communicate using the secondary node 715.

[0141] For example, as shown by reference number 735, the first wireless node can transmit one or more periodic signals to the secondary node 715. The secondary node 715 can forward (e.g., repeat, reflect, and / or relay, among other examples) the periodic signals. The periodic signals can include synchronization signal blocks (SSBs), channel state information reference signals (CSI-RSs), and / or discovery signals, among other examples. In some aspects, the first wireless node can transmit a first set of SSBs (or other reference signals, as described above) to the secondary node 715, and can transmit a second set of SSBs (or other reference signals, as described above) for use in not utilizing the secondary node 715 for an initial access procedure with the first wireless node 710. In this way, the reference signals (e.g., SSBs) used by the first wireless node 710 to establish a communication connection using the secondary node 715 can be different from the reference signals (e.g., SSBs) used by the first wireless node 710 to establish a communication connection without using the secondary node 715.

[0142] For example, a first set of SSBs can be associated with a first periodicity and a second set of SSBs can be associated with a second periodicity. In some aspects, the first periodicity can be a lower periodicity than the second periodicity to conserve resources associated with transmitting SSBs to the secondary node 715. In some aspects, the first set of SSBs can be transmitted using a first frequency and the second set of SSBs can be transmitted using a second frequency. For example, the second set of SSBs (for initial access procedures that do not utilize the secondary node 715) can be associated with a synchronization channel raster (e.g., that indicates frequencies and / or other numerologies associated with SSBs). The first set of SSBs (for initial access procedures that utilize the secondary node 715) can be associated with a different frequency and / or numerology than indicated by the synchronization channel raster.

[0143] As shown by reference number 740, the second wireless node 720 can monitor for periodic signals (e.g., SSBs, CSI-RSs, and / or discovery signals) transmitted by the first wireless node 710 via the secondary node 715. For example, the second wireless node 720 can monitor for the periodic signals on one or more resources (e.g., time-domain resources, frequency-domain resources, and / or spatial-domain resources) indicated by the controlling node 705 and / or the first wireless node 710.

[0144] As shown by reference number 745, the second wireless node 720 can transmit a link establishment request to the first wireless node 710 via the secondary node 715 based at least in part on receiving one or more periodic signals transmitted by the first wireless node 710. The link establishment request can be a request to initiate an initial access procedure, such as a RACH procedure. For example, the link establishment request can be a random access preamble, such as a message A of a two-step RACH procedure, or a message 1 of a four-step RACH procedure, among other examples.

[0145] As shown by reference number 750, the first wireless node 710 can monitor one or more resources for signals from the secondary node 715. For example, the first wireless node 710 can periodically scan for incoming signals from the secondary node 715 during one or more RACH occasions. The first wireless node 710 can receive the link establishment request transmitted by the second wireless node 720 based at least in part on monitoring the one or more resources for signals from the secondary node 715.

[0146] In some aspects, the first wireless node 710 can not transmit the periodic signal as described above with respect to reference number 735. The first wireless node 710 can monitor one or more resources for a signal from the assisting node 715 (e.g., without transmitting the periodic signal). The second wireless node 720 can determine that the one or more resources are being monitored by the first wireless node 710 (e.g., based at least in part on an indication of the assisting node 715 and / or associated resources received from the controlling node 705 and / or the first wireless node 710, as described above). The second wireless node 720 can transmit the link establishment request (e.g., without receiving the periodic signal as described above) such that the assisting node 715 forwards the link establishment request during the one or more resources being monitored by the first wireless node 710.

[0147] As described above, the first wireless node 710 and the second wireless node 720 can perform an initial access procedure via the assisting node 715 based at least in part on the first wireless node 710 receiving the link establishment request. The first wireless node 710 and the second wireless node 720 can establish a communication connection (e.g., a communication link) via the assisting node 715 based at least in part on performing the initial access procedure. For example, the first wireless node 710 and / or the second wireless node 720 can determine one or more beams to use for communicating with each other via the assisting node 715.

[0148] In some aspects, the first wireless node 710 and / or the second wireless node 720 can reconfigure the assisting node 715 to improve end-to-end communication performance between the first wireless node 710 and the second wireless node 720. For example, as shown by reference number 755, the first wireless node 710 can transmit one or more reference signals to the assisting node 715, which are forwarded by the assisting node 715 using one or more different forwarding configurations (e.g., using different transmit powers, in different spatial directions (e.g., using different transmit beam directions and / or different receive beam directions), using different reflection directions, using different reflection configurations, and / or the like). In some aspects, the assisting node 715 can be configured (e.g., by the controlling node 705, the first wireless node 710, and / or the second wireless node 720) to forward the one or more reference signals using the one or more different forwarding configurations. The second wireless node 720 can receive the one or more reference signals using the different forwarding configurations.

[0149] As shown by reference number 760, the first wireless node 710 and / or the second wireless node 720 (and / or the control node 705) can determine a configuration of the auxiliary node 715 based at least in part on the one or more reference signals transmitted using the different forwarding configurations, the configuration for using the auxiliary node 715 to communicate between the first wireless node 710 and the second wireless node 720. For example, the second wireless node 720 can receive the one or more reference signals using the different forwarding configurations and can measure the one or more reference signals to determine one or more end-to-end measurements (e.g., reference signal received power (RSRP) measurements, reference signal received quality (RSRQ) measurements, and / or signal-to-noise (SNR) measurements, etc.) associated with the one or more reference signals. In some aspects, the second wireless node 720 can transmit an indication of the one or more end-to-end measurements to the first wireless node 710 and / or the control node 705.

[0150] The first wireless node 710 and / or the second wireless node 720 (and / or the control node 705) can determine a forwarding configuration of the auxiliary node 715 based at least in part on the one or more end-to-end measurements, the forwarding configuration for using the auxiliary node 715 to communicate between the first wireless node 710 and the second wireless node 720. For example, the first wireless node 710 and / or the second wireless node 720 (and / or the control node 705) can determine a reference signal associated with a best end-to-end measurement. The first wireless node 710 and / or the second wireless node 720 (and / or the control node 705) can determine a forwarding configuration of the auxiliary node 715 to use to forward the reference signal associated with the best end-to-end measurement. The first wireless node 710 and / or the second wireless node 720 (and / or the control node 705) can configure the auxiliary node 715 to use the auxiliary node 715 for one or more future communications between the first wireless node 710 and the second wireless node 720 using the forwarding configuration of the auxiliary node 715 to forward the reference signal associated with the best end-to-end measurement.

[0151] In some aspects, where the first wireless node 710 determines the forwarding configuration of the assisting node 715, the first wireless node 710 can transmit an indication of the forwarding configuration of the assisting node 715 to the assisting node 715, the second wireless node 720, and / or the controlling node 705. In some aspects, where the controlling node 705 determines the forwarding configuration of the assisting node 715, the controlling node 705 can transmit an indication of the forwarding configuration of the assisting node 715 to the assisting node 715, the first wireless node 710, and / or the first wireless node 710. In some aspects, where the second wireless node 720 determines the forwarding configuration of the assisting node 715, the second wireless node 720 can transmit an indication of the forwarding configuration of the assisting node 715 to the assisting node 715, the first wireless node 710, and / or the controlling node 705.

[0152] As shown by reference number 765, the first wireless node 710 and the second wireless node 720 can communicate using the assisting node 715 via the communication connection established as described above. For example, the first wireless node 710 can transmit a communication to the assisting node 715. The assisting node 715 can forward (e.g., transmit, repeat, reflect, and / or relay, among other examples) the communication to the second wireless node 720. In some aspects, the second wireless node 720 can transmit a communication to the assisting node 715. The assisting node 715 can forward (e.g., transmit, repeat, reflect, and / or relay, among other examples) the communication to the first wireless node 710.

[0153] Thus, a wireless node (e.g., the first wireless node 710 and / or the second wireless node 720) can be enabled to utilize the assisting node 715 to transmit or receive communications with another wireless node. In some aspects, a wireless node can be enabled to utilize identification information associated with the assisting node 715 for interference management, beam management, power control, resource allocation, scheduling, mobility and handover procedures, or positioning, among other examples. Thus, a wireless node can be enabled to make better determinations of how or when to utilize the assisting node 715 for communications. Moreover, communication efficiency within a wireless network can be improved based at least in part on availability of identification information of assisting nodes within the wireless network.

[0154] As described above, Figure 7 are provided by way of example. Other examples can differ Figure 7 from the described examples.
