[0001] This patent application claims priority to U.S. Patent Application No. 18 / 362,783, filed July 31, 2023, entitled “MULTIPLE ELECTROMAGNETICRADIATION REFLECTION RELAY NETWORK NODE OPERATIONS”, assigned to the assignee of this application. The disclosure of the earlier application is considered part of this patent application and is incorporated herein by reference. Technical Field

[0002] All aspects of this disclosure relate to wireless communication, and specifically to techniques and apparatus for operating nodes in a multi-electromagnetic-radiation-reflection relay network. Background Technology

[0003] Wireless communication systems are widely deployed to provide a variety of telecommunications services, such as telephone, video, data, messaging, and broadcasting. Typical wireless communication systems employ multiple access technologies that enable 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 issued by the 3rd Generation Partnership Project (3GPP).

[0004] A wireless network may include one or more network nodes that support communication for wireless communication devices, such as user equipment (UE) or multiple UEs. A UE may communicate with network nodes via downlink and uplink communication. A "downlink" (or "DL") refers to the communication link from the network node to the UE, and an "uplink" (or "UL") refers to the communication link from the UE to the network node. Some wireless networks may support device-to-device communication, such as via local links (e.g., sidelinks (SL), wireless local area network (WLAN) links, and / or wireless personal area network (WPAN) links, etc.).

[0005] The aforementioned multiple access technologies have been adopted in various telecommunications standards to provide a common protocol that enables different UEs to communicate at the city, country, region, and / or global levels. New Radio (NR) (which may be referred to as 5G) is a set of enhancements to the LTE mobile standard issued by 3GPP. NR is designed to better support mobile broadband internet access by: improving spectrum efficiency; reducing costs; improving service; utilizing new spectrum; and using Orthogonal Frequency Division Multiplexing (OFDM) with Cyclic Prefix (CP) on the downlink (CP-OFDM), and using CP-OFDM and / or Single Carrier Frequency Division Multiplexing (SC-FDM) (also known as Discrete Fourier Transform Extended OFDM (DFT-s-OFDM)) on the uplink, as well as supporting beamforming, multiple-input multiple-output (MIMO) antenna technologies and carrier aggregation to better integrate with other open standards. Further improvements to LTE, NR, and other radio access technologies remain useful as the demand for mobile broadband access continues to increase. Summary of the Invention

[0037] In some cases, obstacles may obstruct line-of-sight (LoS) communication between network nodes and user equipment (UE). To facilitate communication with the UE, network nodes may utilize electromagnetic reflection relay network nodes, which include, for example, radio frequency reflection arrays configured to perform radio frequency reflection services (e.g., anomalous reflection) in a desired direction. Electromagnetic reflection relay network nodes can be, for example, reconfigurable smart surfaces (RIS) (also referred to as smart reflective surfaces (IRS)). Electromagnetic reflection relay network nodes can change the direction of reflection (e.g., guide reflection in a specific direction) and / or perform intentional refraction (e.g., using transmissive-reflective surfaces). In some cases, low deployment costs may lead to a surge in electromagnetic reflection relay network node deployment. However, without efficient coordination among electromagnetic reflection relay network nodes, their parallel deployment can result in interference, reduced link stability, and / or inefficient use of network resources.

[0038] Some aspects of the technology described herein may include multi-route (e.g., multi-hop) reflective relay network node strategies and associated signaling aspects for operating multiple electromagnetic radiation reflective relay network nodes while serving a UE. In some aspects, for example, a network node may communicate with the UE through a first (e.g., primary) electromagnetic radiation reflective relay network node and at least one additional (e.g., secondary) electromagnetic radiation reflective relay network node. In some aspects, one or more of the at least one additional electromagnetic radiation reflective relay network node may be directly reachable from the network node, and in some aspects, one or more of the at least one additional electromagnetic radiation reflective relay network node may not be directly reachable from the network node. In some aspects, for example, the primary electromagnetic radiation reflective relay network node (in some cases, it may be referred to as an "auxiliary node") may facilitate the discovery of at least one additional electromagnetic radiation reflective relay network node. Electromagnetic radiation reflective relay network nodes can be used to increase signal reception power at the UE and / or suppress interference.

[0039] In this way, some aspects may include using one or more secondary electromagnetic reflection relay network nodes to avoid link failures without any additional delay due to multiple network nodes, since reflection itself does not introduce any delay (e.g., for Ultra-Reliable and Low-Latency Communication (URLLC)). Therefore, some aspects can positively impact network performance. In some aspects, using one or more secondary electromagnetic reflection relay network nodes can reduce interference to locations around the primary communication path. In some aspects, network nodes can use electromagnetic reflection relay network nodes to multiplex UE data (e.g., via spatial division multiplexing (SDM), time division duplex (TDD), and / or frequency division multiplexing (FDM)) and / or operate to form a primary and secondary communication path for robust operation (e.g., to mitigate link failures and / or minimize latency to support URLLC schemes).

[0040] Various aspects of this disclosure are described more fully below with reference to the accompanying drawings. However, this disclosure can be embodied in many different forms and should not be construed as limited to any particular structure or function presented throughout this disclosure. Rather, these aspects are provided so that this disclosure will be comprehensive and complete, and will fully convey the scope of protection of this disclosure to those skilled in the art.

[0042] This disclosure can be readily used as the basis for modifying or designing other structures for performing the same purposes as this disclosure. Such equivalent constructions do not depart from the scope of the appended claims. The characteristics of the concepts disclosed herein (both their organization and manner of operation) and their associated advantages are better understood in conjunction with the accompanying drawings, based on the following description. Each figure provided in the drawings is for illustrative and descriptive purposes and not as a definition of limitation of the claims.

[0043] While aspects are described herein by way of example, such aspects can be implemented in many different arrangements and scenarios. The techniques described herein can be implemented using different platform types, devices, systems, shapes, sizes, and / or package arrangements. For example, some aspects can be implemented via integrated chip implementations or other devices based on non-modular components (e.g., end-user equipment, vehicles, communication equipment, computing devices, industrial equipment, retail / shopping devices, medical devices, and / or artificial intelligence devices). Aspects can be implemented in chip-level components, modular components, non-modular components, non-chip-level components, device-level components, and / or system-level components. Devices incorporating the described aspects and features may include additional components and features for implementing and practicing the claimed and described aspects.

[0044] Various devices and techniques will now be used to illustrate several aspects of a telecommunications system. These devices and techniques will be described in detail below and illustrated in the accompanying drawings by various boxes, modules, components, circuits, steps, processes, or algorithms (collectively, “elements”). These elements can be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the system as a whole.

[0045] Although terms generally associated with 5G or New Radio (NR) Radio Access Technology (RAT) may be used herein to describe aspects, aspects of this disclosure may be applied to other RATs, such as 3G RAT, 4G RAT and / or 5G and later (e.g., 6G) RATs.

[0046] Figure 1This is a diagram illustrating an example of a wireless network 100 according to the present disclosure. The wireless network 100 may be a 5G (e.g., NR) network and / or a 4G (e.g., Long Term Evolution (LTE)) network, or may include elements of a 5G (e.g., NR) network and / or elements of a 4G (e.g., LTE) network, etc. The wireless network 100 may include one or more network nodes 110 (shown as network node 110a, network node 110b, network node 110c, and network node 110d), one or more UEs 120 (shown as UE 120a, UE 120b, UE 120c, UE 120d, and UE 120e), and / or other entities. Network node 110 is a network node that communicates with UE 120. As shown, network node 110 may include one or more network nodes. For example, network node 110 can be an aggregated network node, meaning that the aggregated network node is configured to utilize a radio protocol stack that is physically or logically integrated within a single radio access network (RAN) node (e.g., within a single device or unit). As another example, network node 110 can be a decomposed network node (sometimes referred to as a decomposed base station), meaning that network node 110 is configured to utilize a protocol stack that is physically or logically distributed among two or more nodes (such as one or more central units (CUs), one or more distributed units (DUs), or one or more radio units (RUs)).

[0047] In some examples, network node 110 is a network node (such as RU) that communicates with UE 120 via a radio access link, or includes network nodes (such as RU) that communicate with UE 120 via a radio access link. In some examples, network node 110 is a network node (such as DU) that communicates with other network nodes 110 via a fronthaul link or a midhaul link, or includes network nodes (such as DU) that communicate with other network nodes 110 via a fronthaul link or a midhaul link. In some examples, network node 110 is a network node (such as CU) that communicates with other network nodes 110 via a midhaul link or with the core network via a backhaul link, or includes network nodes (such as CU) that communicate with other network nodes 110 via a midhaul link or with the core network via a backhaul link. In some examples, network node 110 (such as aggregated network node 110 or decomposed network node 110) may include multiple network nodes, such as one or more RUs, one or more CUs, and / or one or more DUs. Network node 110 may include, for example, NR base stations, LTE base stations, Node Bs, eNBs (e.g., in 4G), gNBs (e.g., in 5G), access points, Transmit / Receive Points (TRPs), DUs, RUs, CUs, network mobility elements, core network nodes, network elements, network equipment, RAN nodes, or combinations thereof. In some examples, network nodes 110 may interconnect with each other or with one or more other network nodes 110 in the wireless network 100 using any suitable transport network through various types of fronthaul interfaces, midhaul interfaces, and / or backhaul interfaces (such as direct physical connections, air interfaces, or virtual networks).

[0048] In some examples, network node 110 may provide communication coverage for a specific geographic area. In the 3rd Generation Partnership Project (3GPP), depending on the context in which the term is used, the term "cell" may refer to the coverage area of ​​network node 110 and / or the network node subsystem serving that coverage area. Network node 110 may provide communication coverage for macrocells, picocells, femtocells, and / or another type of cell. A macrocell may cover a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access by UE 120 with a service subscription. A picocell may cover a relatively small geographic area and may allow unrestricted access by UE 120 with a service subscription. A femtocell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by UE 120 associated with the femtocell (e.g., UE 120 in a Closed Subscriber Group (CSG)). Network node 110 used for macrocells may be referred to as a macro network node. Network node 110 used for picocells may be referred to as a pico network node. The network node 110 used for femtocells can be referred to as a femtocell network node or a home network node. Figure 1 In the example shown, network node 110a may be a macro network node for macro cell 102a, network node 110b may be a pico network node for pico cell 102b, and network node 110c may be a femto network node for femto cell 102c. Network nodes may support one or more (e.g., three) cells. In some examples, the cells may not necessarily be stationary, and the geographical area of ​​the cells may move depending on the location of the mobile network node 110 (e.g., a mobile network node).

[0049] In some aspects, the term "base station" or "network node" may refer to an aggregated base station, a decomposed base station, an integrated access and backhaul (IAB) node, a relay node, or one or more components thereof. For example, in some aspects, "base station" or "network node" may refer to a CU, DU, RU, a near real-time (near RT) RAN intelligent controller (RIC), or a non-real-time (non-RT) RIC, or a combination thereof. In some aspects, the term "base station" or "network node" may refer to a device configured to perform one or more functions (such as those described herein in conjunction with network node 110). In some aspects, the term "base station" or "network node" may refer to multiple devices configured to perform one or more functions. For example, in some distributed systems, each of multiple different devices (which may be located in the same geographical location or different geographical locations) may be configured to perform at least a portion of a function, or to repeatedly perform at least a portion of that function, and the term "base station" or "network node" may refer to any one or more of these different devices. In some aspects, the term "base station" or "network node" may refer to one or more virtual base stations or one or more virtual base station functions. For example, in some aspects, two or more base station functions can be instantiated on a single device. In some aspects, the term "base station" or "network node" may refer to one base station function rather than another. In this way, a single device may include more than one base station.

[0050] Wireless network 100 may include one or more relay stations. A relay station is a network node that can receive data transmissions from upstream nodes (e.g., network node 110 or UE 120) and transmit data to downstream nodes (e.g., UE 120 or network node 110). A relay station may be a UE 120 that can relay transmissions to other UE 120s. Figure 1 In the example shown, network node 110d (e.g., a relay network node) can communicate with network node 110a (e.g., a macro network node) and UE 120d to facilitate communication between network node 110a and UE 120d. The network node 110 for relay communication may be referred to as a relay station, relay base station, relay network node, relay node, relay, etc.

[0051] Wireless network 100 can be a heterogeneous network, comprising different types of network nodes 110, such as macro network nodes, pico network nodes, femto network nodes, relay network nodes, etc. These different types of network nodes 110 may have different transmit power levels, different coverage areas, and / or different effects on interference in wireless network 100. For example, macro network nodes may have high transmit power levels (e.g., 5 watts to 40 watts), while pico network nodes, femto network nodes, and relay network nodes may have lower transmit power levels (e.g., 0.1 watts to 2 watts).

[0052] Network controller 130 may be coupled to or communicate with a group of network nodes 110, and may provide coordination and control for these network nodes 110. Network controller 130 may communicate with network nodes 110 via a backhaul or midhaul link. Network nodes 110 may also communicate directly with each other, or indirectly via a wireless or wired backhaul link. In some aspects, network controller 130 may be a CU or core network device, or may include a CU or core network device.

[0053] UE 120 may be distributed throughout the wireless network 100, and each UE 120 may be stationary or mobile. UE 120 may include, for example, access terminals, terminals, mobile stations, and / or subscriber units. UE 120 may be a cellular phone (e.g., a smartphone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet computer, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device, a biometric device, a wearable device (e.g., a smartwatch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring or smart bracelet)), an entertainment device (e.g., a music device, a video device, and / or a satellite radio), a vehicle component or sensor, a smart meter / sensor, industrial manufacturing equipment, a GPS device, a UE function of a network node, and / or any other suitable device configured to communicate via wireless or wired media.

[0054] Some UEs 120 may be considered machine-type communication (MTC) or evolved or enhanced machine-type communication (eMTC) UEs. MTC UEs and / or eMTC UEs may include, for example, robots, unmanned aerial vehicles, remote devices, sensors, instruments, monitors, and / or location tags that can communicate with network nodes, another device (e.g., a remote device), or some other entity. Some UEs 120 may be considered Internet of Things (IoT) devices and / or may be implemented as NB-IoT (Narrowband IoT) devices. Some UEs 120 may be considered customer premises equipment. UEs 120 may be included within a housing that houses the components of the UE 120, such as processor components and / or memory components. In some examples, the processor components and memory components may be coupled together. For example, the processor components (e.g., one or more processors) and memory components (e.g., memory) may be operatively coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0055] Generally, any number of wireless networks 100 can be deployed in a given geographical area. Each wireless network 100 can support a specific RAT and can operate on one or more frequencies. A RAT may be referred to as a radio technology, air interface, etc. A frequency may be referred to as a carrier, frequency channel, etc. Each frequency in a given geographical area can support a single RAT to avoid interference between wireless networks using different RATs. In some cases, NR or 5G RAT networks can be deployed.

[0056] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more sidelink channels (e.g., without using network node 110 as an intermediary device to communicate with each other). For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, or vehicle-to-pedestrian (V2P) protocols) and / or mesh networks. In such examples, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by network node 110.

[0057] Devices in Wireless Network 100 can communicate using the electromagnetic spectrum, which can be subdivided into various categories, bands, channels, etc., based on frequency or wavelength. For example, devices in Wireless Network 100 can communicate using one or more operating frequency bands. In 5G NR, two initial operating frequency bands have been designated as frequency ranges FR1 (410MHz to 7.125GHz) and FR2 (24.25GHz to 52.6GHz). It should be understood that although a portion of FR1 is greater than 6GHz, FR1 is generally (interchangeably) referred to as the “sub-6GHz” band in various documents and articles. Similar naming issues sometimes occur with FR2, which is generally (interchangeably) referred to as the “millimeter wave” band in documents and articles, although this is different from the Extremely High Frequency (EHF) band (30GHz to 300GHz) designated as a “millimeter wave” band by the International Telecommunication Union (ITU).

[0058] The frequencies between FR1 and FR2 are generally referred to as mid-band frequencies. Recent 5G NR studies have identified the operating bands used for these mid-band frequencies as the frequency range designation FR3 (7.125 GHz to 24.25 GHz). Bands falling within FR3 can inherit FR1 and / or FR2 characteristics, thus effectively extending the features of FR1 and / or FR2 to mid-band frequencies. Furthermore, higher frequency bands are currently being explored to extend 5G NR operation beyond 52.6 GHz. For example, three higher operating bands have been identified as the frequency range designations FR4a or FR4-1 (52.6 GHz to 71 GHz), FR4 (52.6 GHz to 114.25 GHz), and FR5 (114.25 GHz to 300 GHz). Each of these higher frequency bands falls within the EHF band.

[0059] Considering the examples above, unless otherwise specifically stated, it should be understood that if the term "below 6 GHz" is used herein, it can broadly refer to frequencies below 6 GHz, within FR1, or including intermediate frequency bands. Furthermore, unless otherwise specifically stated, it should be understood that if the term "millimeter wave" is used herein, it can broadly refer to frequencies that can include intermediate frequency bands, within FR2, FR4, FR4-a, or FR4-1 and / or FR5, or within the EHF band. Modifications to frequencies included in these operating frequency bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, and / or FR5) are contemplated, and the techniques described herein are applicable to those modified frequency ranges.

[0060] In some aspects, the UE (e.g., UE 120) may include a communication manager 140. As described in more detail elsewhere herein, the communication manager 140 may communicate with a network node for a period of time via a primary communication path, the primary communication path including a link between the network node and a first electromagnetic radiation reflection relay network node and a link between the first electromagnetic radiation reflection relay network node and the UE; and during the same period of time, communicate with the network node via at least one secondary communication path, the at least one secondary communication path including a link between the UE and a second electromagnetic radiation reflection relay network node. Additionally or alternatively, the communication manager 140 may perform one or more other operations described herein.

[0061] In some aspects, a network node (e.g., network node 110) may include a communication manager 150. As described in more detail elsewhere herein, the communication manager 150 may communicate with the UE for a period of time via a primary communication path, which includes a link between the network node and a first electromagnetic radiation reflection relay network node and a link between the first electromagnetic radiation reflection relay network node and the UE; and during the same period of time, communicate with the UE via at least one secondary communication path, which includes a link between the UE and a second electromagnetic radiation reflection relay network node.

[0062] In some aspects, the communication manager 150 may receive configuration information from the network node indicating configurations for communicating with the UE; and communicate with the UE via a main communication path for a period of time, the main communication path including a link between the network node and the first electromagnetic radiation reflection relay network node and a link between the first electromagnetic radiation reflection relay network node and the UE.

[0063] In some aspects, the communication manager 150 may receive configuration information from a network node indicating a configuration for communicating with the UE; and communicate with the UE for a period of time via a secondary communication path, the secondary communication path including a link between the network node and a first electromagnetic radiation reflection relay network node and a link between the first electromagnetic radiation reflection relay network node and the second electromagnetic radiation reflection relay network node. Additionally or alternatively, the communication manager 150 may perform one or more other operations described herein.

[0064] As indicated above, Figure 1 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 1 The examples described are different.

[0065] Figure 2 This is a diagram illustrating example 200 of communication between network node 110 and UE 120 in a wireless network 100 according to this disclosure. Network node 110 may be equipped with a set of antennas 234a to 234t, such as... T One antenna ( T ≥1). The UE 120 may be equipped with a set of antennas 252a to 252r, such as R One antenna ( R ≥1). Network node 110 of Example 200 includes one or more radio frequency components, such as antenna 234 and modem 232. In some examples, network node 110 may include an interface, communication components, or another component that facilitates communication with UE 120 or another network node. Some network node 110 may not include radio frequency components that facilitate direct communication with UE 120, such as one or more CUs or one or more DUs.

[0066] At network node 110, transmitting processor 220 can receive data from data source 212 intended for use by UE 120 (or a group of UEs 120). Transmitting processor 220 can select one or more modulation and decoding schemes (MCS) for UE 120, at least in part, based on one or more Channel Quality Indicators (CQIs) received from UE 120. Network node 110 can process (e.g., encode and modulate) the data for UE 120, at least in part, based on the MCS selected for UE 120, and can provide data symbols for UE 120. Transmitting processor 220 can process system information (e.g., for Semi-Static Resource Allocation Information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper-layer signaling), and provide overhead symbols and control symbols. Transmitting processor 220 can generate reference symbols for reference signals (e.g., Cell-Specific Reference Signal (CRS) or Demodulation Reference Signal (DMRS)) and synchronization signals (e.g., Primary Synchronization Signal (PSS) or Secondary Synchronization Signal (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 can perform spatial processing (e.g., pre-decoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols where applicable, and can transmit a set of output symbol streams (e.g., T Each output symbol stream is provided to a corresponding set of modems 232 (e.g., ...). T Each modem 232a to 232t may be used to process a corresponding output symbol stream (e.g., for OFDM) to obtain an output sample stream. For example, each output symbol stream may be provided to a modulator component (shown as MOD) of modem 232. Each modem 232 may use a corresponding modulator component to process the corresponding output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modem 232 may also use a corresponding modulator component to process the output sample stream (e.g., convert to analog, amplify, filter, and / or up-convert) to obtain a downlink signal. Modems 232a to 232t may be used via a set of corresponding antennas 234 (e.g., T Each antenna (shown as antennas 234a to 234t) is used to transmit a set of downlink signals (e.g., ...). T (One downlink signal).

[0067] At UE 120, a set of antennas 252 (shown as antennas 252a to 252r) can receive downlink signals from network node 110 and / or other network nodes 110 and can transmit a set of received signals (e.g., R The received signals are provided to a group of modems 254 (e.g., RA modem 254 (shown as modems 254a to 254r). For example, each received signal may be provided to a demodulator component (shown as DEMOD) of modem 254. Each modem 254 may use a corresponding demodulator component to condition the received signal (e.g., filter, amplify, down-convert, and / or digitize) to obtain an input sample. Each modem 254 may use the demodulator component to further process the input sample (e.g., for OFDM) to obtain a received symbol. MIMO detector 256 may obtain the received symbols from modem 254, perform MIMO detection on the received symbols where applicable, and provide the detected symbols. Receiver processor 258 may process (e.g., demodulate and decode) the detected symbols, provide the decoded data for UE 120 to data sink 260, and provide the decoded control information and system information to controller / processor 280. The term "controller / processor" may refer to one or more controllers, one or more processors, or a combination thereof. The channel processor can determine parameters such as the Reference Signal Received Power (RSRP), Received Signal Strength Indicator (RSSI), Reference Signal Received Quality (RSRQ), and / or CQI. In some examples, one or more components of the UE 120 may be included in the housing 284.

[0068] Network controller 130 may include communication unit 294, controller / processor 290, and memory 292. Network controller 130 may include one or more devices, for example, in a core network. Network controller 130 may communicate with network node 110 via communication unit 294.

[0069] One or more antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include one or more antenna panels, one or more antenna groups, one or more sets of antenna elements and / or one or more antenna arrays, etc., or may be included within one or more antenna panels, one or more antenna groups, one or more sets of antenna elements and / or one or more antenna arrays, etc. Antenna panels, antenna groups, sets of antenna elements and / or antenna arrays may include one or more antenna elements (within a single housing or multiple housings), a set of coplanar antenna elements, a set of non-coplanar antenna elements and / or be coupled to one or more transmitting and / or receiving components (such as...). Figure 2 One or more antenna elements (one or more components in a )

[0070] Each antenna element may include one or more sub-elements for radiating or receiving radio frequency signals. For example, a single antenna element may include a first sub-element that is cross-polarized with a second sub-element, which can be used to independently transmit cross-polarized signals. Antenna elements may include patch antennas, dipole antennas, or other types of antennas arranged in a linear pattern, a two-dimensional pattern, or another pattern. The spacing between antenna elements allows signals transmitted individually by the antenna elements at desired wavelengths to interact or interfere with each other (e.g., to form a desired beam). For example, given a desired wavelength or frequency range, the spacing may provide a quarter wavelength, half wavelength, or other fraction of the wavelength between adjacent antenna elements to allow interaction or interference of signals transmitted by individual antenna elements within that desired range.

[0071] Antenna elements and / or sub-elements can be used to generate a beam. A “beam” can specify a wireless signal to be transmitted, such as in the direction of a receiving device. A beam may include a directional signal, a direction associated with the signal, a set of directional resources associated with the signal (e.g., angle of arrival, horizontal direction, vertical direction), and / or a set of parameters indicating one or more aspects of the directional signal, the direction associated with the signal, and / or the set of directional resources associated with the signal.

[0072] As indicated above, antenna elements and / or sub-elements can be used to generate beams. For example, antenna elements can be individually selected or deselected for the transmission of signals (or multiple signals) by controlling the amplitude of one or more corresponding amplifiers. Beamforming involves generating a beam using multiple signals on different antenna elements, wherein one or more or all of these signals are phase-shifted relative to each other. The formed beam can carry physical or higher-level reference signals or information. As each of the multiple signals is radiated from its respective antenna element, the radiated signals interact with, interfere with (constructive and destructive interference), and are amplified to form the resulting beam. The shape (such as amplitude, width, and / or the presence of sidelobes) and orientation (such as the angle of the beam relative to the surface of the antenna array) can be dynamically controlled by modifying the phase shifts or phase offsets of the multiple signals relative to each other.

[0073] Beamforming can be used for communication between a UE and a network node, such as for millimeter-wave communication. In such cases, the network node can provide the UE with a Transmit Configuration Indicator (TCI) state configuration, which indicates the beams that the UE can use, for example, to receive the Physical Downlink Shared Channel (PDSCH). The TCI state indicates the spatial parameters used for communication. For example, the TCI state for communication can identify the source signal (such as a synchronization signal block, channel state information reference signal, etc.) and the spatial parameters to be derived from the source signal for the purpose of transmitting or receiving communication. For example, the TCI state can indicate a Quasi-Co-location (QCL) type. The QCL type can indicate one or more spatial parameters to be derived from the source signal. The source signal can be referred to as a QCL source. The network node can indicate an active TCI state to the UE, which the UE can use to select the beam for receiving the PDSCH.

[0074] Beam indication can be or includes TCI status information elements, beam identifier (ID), spatial relationship information, TCI status ID, closed-loop index, panel ID, TRP ID, and / or sounding reference signal (SRS) set ID, etc. TCI status information elements (referred to herein as TCI status) can indicate information associated with the beam, such as a downlink beam. For example, a TCI status information element can indicate a TCI status identifier (e.g., tci-StateID ), QCL type (e.g., qcl-Type1 , qcl-Type2 , qcl-TypeA , qcl-TypeB , qcl-TypeC , qcl-TypeD etc.), community signage (e.g., ServCellIndex ), bandwidth identifier ( bwp-Id ), reference signal identifiers (such as CSI-RS (e.g., NZP-CSI-RS-ResourceId , SSB-Index Spatial relationship information can similarly indicate information associated with the uplink beam.

[0075] Beam indication can be a combined or separate downlink (DL) / uplink (UL) beam indication within a unified TCI framework. In some cases, the network may use at least UE-specific (unicast) downlink control information (DCI) to indicate a combined or separate DL / UL beam indication from an active TCI state, thereby supporting Layer 1 (L1) based beam indication. In some cases, existing DCI formats 1_1 and / or 1_2 may be reused for beam indication. The network may include support mechanisms for UE confirmation of successful decoding of the beam indication. For example, acknowledgment / negation acknowledgment (ACK / NACK) of a PDSCH scheduled via a DCI carrying the beam indication may also be used as an ACK for the DCI.

[0076] Beam indication can be provided for carrier aggregation (CA) scenarios. Within a unified TCI framework, the network can support public TCI state ID updates and activations to provide public QCL information and / or one or more public UL transmit spatial filters across a set of configured component carriers (CCs). This type of beam indication can be applied to in-band CA as well as joint DL / UL beam indication and individual DL / UL beam indication. The public TCI state ID can refer to a reference signal (RS) determined based on the TCI state indicated by the public TCI state ID, used to provide QCL type D indication and to determine the UL transmit spatial filters across that set of configured CCs.

[0077] On the uplink, at UE 120, the transmit processor 264 can receive and process data from data source 262 and control information from controller / processor 280 (e.g., for reporting including RSRP, RSSI, RSRQ, and / or CQI). The transmit processor 264 can generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 can be pre-decoded by the TX MIMO processor 266 where applicable, further processed by the modem 254 (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to network node 110. In some examples, the modem 254 of UE 120 may include a modulator and demodulator. In some examples, UE 120 includes a transceiver. The transceiver may include any combination of antenna 252, modem 254, MIMO detector 256, receive processor 258, transmit processor 264, and / or TX MIMO processor 266. The transceiver may be used by a processor (e.g., controller / processor 280) and memory 282 to execute this document (e.g., reference). Figures 5 to 11 ( ) any aspect of the methods described in the method.

[0078] At network node 110, uplink signals from UE 120 and / or other UEs may be received by antenna 234, processed by modem 232 (e.g., demodulator component of modem 232 (shown as DEMOD)), detected by MIMO detector 236 (where applicable), and further processed by receive processor 238 to obtain decoded data and control information transmitted by UE 120. Receive processor 238 may provide the decoded data to data sink 239 and the decoded control information to controller / processor 240. Network node 110 may include communication unit 244 and may communicate with network controller 130 via communication unit 244. Network node 110 may include scheduler 246 to schedule one or more UEs 120 for downlink and / or uplink communication. In some examples, modem 232 of network node 110 may include modulator and demodulator. In some examples, network node 110 includes transceiver. The transceiver may include any combination of antenna 234, modem 232, MIMO detector 236, receive processor 238, transmit processor 220, and / or TX MIMO processor 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to execute this document (e.g., reference). Figures 5 to 11 ( ) any aspect of the methods described in the method.

[0079] The controller / processor 240 of network node 110, the controller / processor 280 of UE 120 and / or Figure 2 Any other components may perform one or more techniques associated with the operation of a multi-electromagnetic radiation reflection relay network node, as described in more detail elsewhere herein. For example, the controller / processor 240 of network node 110, the controller / processor 280 of UE 120, and / or Figure 2 Any other component that can execute or direct, for example Figure 6 Process 600 Figure 7 Process 700 Figure 8 The process 800 Figure 9 The operation of process 900 and / or other processes as described herein. Memory 242 and memory 282 may store data and program code for network node 110 and UE 120, respectively. In some examples, memory 242 and / or memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, when executed by one or more processors of network node 110 and / or UE 120 (e.g., directly executed, or executed after compilation, transformation, and / or interpretation), these one or more instructions may cause the one or more processors, UE 120, and / or network node 110 to perform or direct, for example... Figure 6 Process 600 Figure 7 Process 700 Figure 8 The process 800 Figure 9 The operation of process 900 and / or other processes as described herein. In some examples, the execution instructions may include run instructions, transform instructions, compile instructions and / or interpret instructions, etc.

[0080] In some aspects, the UE (e.g., UE 120) includes components for communicating with a network node via a primary communication path during a time period, the primary communication path including a link between the network node and a first electromagnetic radiation reflection relay network node and a link between the first electromagnetic radiation reflection relay network node and the UE; and / or components for communicating with the network node via at least one secondary communication path during the time period, the at least one secondary communication path including a link between the UE and a second electromagnetic radiation reflection relay network node. Components for the UE to perform the operations described herein may include, for example, one or more of the following: a communication manager 140, an antenna 252, a modem 254, a MIMO detector 256, a receive processor 258, a transmit processor 264, a TX MIMO processor 266, a controller / processor 280, or a memory 282.

[0081] In some aspects, a network node (e.g., network node 110) includes components for communicating with the UE via a primary communication path during a time period, the primary communication path including a link between the network node and a first electromagnetic radiation reflection relay network node and a link between the first electromagnetic radiation reflection relay network node and the UE; and / or components for communicating with the UE via at least one secondary communication path during the time period, the at least one secondary communication path including a link between the UE and a second electromagnetic radiation reflection relay network node.

[0082] In some aspects, the first electromagnetic radiation reflection relay network node (e.g., network node 110) includes components for receiving configuration information from the network node indicating a configuration for communicating with the UE; and / or components for communicating with the UE via a main communication path over a period of time, the main communication path including a link between the network node and the first electromagnetic radiation reflection relay network node and a link between the first electromagnetic radiation reflection relay network node and the UE.

[0083] In some aspects, the second electromagnetic radiation reflection relay network node (e.g., network node 110) includes components for receiving configuration information from the network node indicating a configuration for communicating with the UE; and / or components for communicating with the UE via a secondary communication path over a period of time, the secondary communication path including a link between the network node and the first electromagnetic radiation reflection relay network node and a link between the first electromagnetic radiation reflection relay network node and the second electromagnetic radiation reflection relay network node. Components for the second electromagnetic radiation reflection relay network node to perform the operations described herein may include, for example, one or more of the following: a communication manager 150, a transmit processor 220, a TX MIMO processor 230, a modem 232, an antenna 234, a MIMO detector 236, a receive processor 238, a controller / processor 240, a memory 242, or a scheduler 246.

[0084] In some respects, a single processor can perform all the functions described as being performed by that one or more processors. In other respects, the one or more processors can jointly perform a set of functions. For example, a first group(s) of the one or more processors can perform a first function described as being performed by that one or more processors, and a second group(s) of the one or more processors can perform a second function described as being performed by that one or more processors. The first group and the second group of processors may be the same group of processors or may be different groups of processors. The reference to "one or more processors" should be understood as referring to a combination of functions. Figure 2 Any one or more processors described. The reference to "one or more memories" should be understood to refer to any one or more memories of the corresponding device, such as those in conjunction with... Figure 2 The memory described. For example, a function described as being performed by one or more memories can be performed by the same subset of the one or more memories or by different subsets of the one or more memories.

[0085] Although Figure 2 The boxes in the diagram are illustrated as different components, but the functions described above with respect to these boxes may be implemented in a single hardware, software, or combined component, or in various combinations of components. For example, the functions described with respect to transmit processor 264, receive processor 258, and / or TX MIMO processor 266 may be performed by or under the control of controller / processor 280.

[0086] As indicated above, Figure 2 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 2 The examples described are different.

[0087] The deployment of communication systems such as 5G NR systems can be arranged in a variety of ways using various components or constituent parts. In a 5G NR system or network, network nodes, network entities, network mobility elements, RAN nodes, core network nodes, network elements, base stations, or network equipment can be implemented in either a converged or decomposed architecture. For example, a base station (such as a Node B (NB), evolved NB (eNB), NR base station, 5G NB, access point (AP), TRP, or cell, etc.) or one or more units (or components) performing base station functionality can be implemented as a converged base station (also known as a standalone base station or monolithic base station) or a decomposed base station. A "network entity" or "network node" can refer to a decomposed base station or one or more units of a decomposed base station (such as one or more CUs, one or more DUs, one or more RUs, or combinations thereof).

[0088] Aggregated base stations (e.g., aggregated network nodes) can be configured to utilize a radio protocol stack that is physically or logically integrated within a single RAN node (e.g., within a single device or cell). Decomposed base stations (e.g., decomposed network nodes) can be configured to utilize a protocol stack that is physically or logically distributed across two or more cells (such as one or more CUs, one or more DUs, or one or more RUs). In some examples, the CU may be implemented within a network node, and one or more DUs may be co-located with the CU, or alternatively, may be geographically or virtually distributed across one or more other network nodes. DUs may be implemented to communicate with one or more RUs. Each of the CU, DU, and RU may also be implemented as a virtual cell, such as a Virtual Central Unit (VCU), a Virtual Distributed Unit (VDU), or a Virtual Radio Unit (VRU), etc.

[0089] Base station type operation or network design can take into account the aggregation characteristics of base station functionality. For example, decomposed base stations can be utilized in IAB networks, Open Radio Access Networks (O-RAN (such as network configurations initiated by the O-RAN Alliance)), or Virtualized Radio Access Networks (vRAN, also known as Cloud Radio Access Networks (C-RAN)) to facilitate the scaling of communication systems by separating base station functionality into one or more units that can be deployed independently. Decomposed base stations can include functionality implemented across two or more units at various physical locations, as well as functionality virtually implemented for at least one unit, which enables flexibility in network design. Each unit of a decomposed base station can be configured for wired or wireless communication with at least one other unit of the decomposed base station.

[0090] Figure 3This is an illustration of an example disaggregated base station architecture 300 according to this disclosure. The disaggregated base station architecture 300 may include a CU 310, which may communicate directly with the core network 320 via a backhaul link, or indirectly with the core network 320 via one or more disaggregated control units (such as near-RT RIC 325 via an E2 link, or a non-RT RIC 315 associated with a Service Management and Orchestration (SMO) framework 305, or both). The CU 310 may communicate with one or more DUs 330 via a corresponding midhaul link (such as via an F1 interface). Each DU 330 may communicate with one or more RUs 340 via a corresponding fronthaul link. Each RU 340 may communicate with one or more UEs 120 via a corresponding radio frequency (RF) access link. In some implementations, a UE 120 may be served simultaneously by multiple RUs 340.

[0091] Each unit in the clusters (including CU 310, DU 330, RU 340), as well as the near-RT RIC 325, non-RT RIC 315, and SMO frame 305, may include or be coupled to one or more interfaces configured to receive or transmit signals, data, or information (collectively, signals) via wired or wireless transmission media. Each unit in the cluster, or an associated processor or controller providing instructions to one or more communication interfaces of the corresponding unit, may be configured to communicate with one or more units in other clusters via transmission media. In some examples, each unit in the cluster may include a wired interface and a wireless interface configured to receive signals via a wired transmission media or transmit signals to one or more units in other clusters, and the wireless interface may include a receiver, transmitter, or transceiver (such as an RF transceiver) configured to receive signals via a wireless transmission media or transmit signals to one or more units in other clusters, or both.

[0092] In some aspects, the CU 310 can host one or more higher-level control functions. Such control functions may include Radio Resource Control (RRC) functions, Packet Data Convergence Protocol (PDCP) functions, or Service Data Adaptation Protocol (SDAP) functions, etc. Each control function can be implemented using an interface configured to signal to other control functions hosted by the CU 310. The CU 310 can be configured to handle user plane functions (e.g., Central Unit-User Plane (CU-UP) functions), control plane functions (e.g., Central Unit-Control Plane (CU-CP) functions), or combinations thereof. In some implementations, the CU 310 can be logically split into one or more CU-UP units and one or more CU-CP units. When implemented in an O-RAN configuration, the CU-UP units can communicate bidirectionally with the CU-CP units via an interface such as an E1 interface. The CU 310 can be implemented to communicate with the DU 330 for network control and signaling purposes, as needed.

[0093] Each DU 330 may correspond to a logical unit comprising one or more base station functions for controlling the operation of one or more RU 340s. In some aspects, the DU 330 may host one or more of the Radio Link Control (RLC) layer, Medium Access Control (MAC) layer, and one or more high physical (PHY) layers, at least in part, according to functional splits (such as those defined by 3GPP). In some aspects, the one or more high PHY layers may be implemented by one or more modules for forward error correction (FEC) encoding and decoding, scrambling, and modulation and demodulation, etc. In some aspects, the DU 330 may also host one or more low PHY layers, such as those implemented by one or more modules for Fast Fourier Transform (FFT), Inverse FFT (iFFT), Digital Beamforming, or Physical Random Access Channel (PRACH) extraction and filtering, etc. Each layer (which may also be referred to as a module) may be implemented using an interface configured to communicate signals with other layers (and modules) hosted by the DU 330 or with control functions hosted by the CU 310.

[0094] Each RU 340 can implement lower-layer functionality. In some deployments, an RU 340 controlled by a DU 330 can correspond to a logical node that hosts RF processing functions or low-PHY layer functions, such as performing FFT, performing iFFT, digital beamforming, or PRACH extraction and filtering, based on function splitting (e.g., function splitting defined by 3GPP) (such as lower-layer function splitting). In such architectures, each RU 340 can be operated to handle over-the-air (OTA) communications with one or more UEs 120. In some specific implementations, the real-time and non-real-time aspects of communication with the control plane and user plane of the RU 340 can be controlled by the corresponding DU 330. In some scenarios, this configuration allows each DU 330 and CU 310 to be implemented in a cloud-based RAN architecture, such as a vRAN architecture.

[0095] The SMO framework 305 can be configured to support RAN deployment and provisioning of both non-virtualized and virtualized network elements. For non-virtualized network elements, the SMO framework 305 can be configured to support the deployment of dedicated physical resources for RAN coverage requirements, which can be managed via operation and maintenance interfaces such as the O1 interface. For virtualized network elements, the SMO framework 305 can be configured to interact with cloud computing platforms such as the Open Cloud (O-Cloud) platform 390 to perform network element lifecycle management (such as instantiating virtualized network elements) via cloud computing platform interfaces such as the O2 interface. Such virtualized network elements may include, but are not limited to, CU 310, DU 330, RU 340, non-RT RIC 315, and near-RTTRIC 325. In some specific implementations, the SMO framework 305 may communicate with the hardware aspects of the 4G RAN, such as the Open eNB (O-eNB) 311, via the O1 interface. Additionally, in some implementations, the SMO framework 305 can communicate directly with each of one or more RUs 340 via a corresponding O1 interface. The SMO framework 305 may also include a non-RT RIC 315 configured to support the functionality of the SMO framework 305.

[0096] The non-RT RIC 315 can be configured to include logical functions enabling non-real-time control and optimization of RAN elements and resources, including artificial intelligence / machine learning (AI / ML) workflows for model training and updates, or policy-based guidance for applications / features in the near-RT RIC 325. The non-RT RIC 315 can be coupled to or communicate with the near-RT RIC 325, such as via an A1 interface. The near-RT RIC 325 can be configured to include logical functions enabling near real-time control and optimization of RAN elements and resources via data collection and actions through an interface such as an E2 interface, connecting one or more CU 310s, one or more DU 330s, or both, and O-eNBs to the near-RT RIC 325.

[0097] In some implementations, to generate AI / ML models to be deployed in the near-RT RIC 325, the non-RT RIC 315 may receive parameters or external enrichment information from an external server. This information can be utilized by the near-RT RIC 325 and can be received from non-network data sources or network functions at the SMO framework 305 or the non-RT RIC 315. In some examples, the non-RT RIC 315 or near-RT RIC 325 may be configured to tune RAN behavior or performance. For example, the non-RT RIC 315 may monitor long-term trends and patterns in performance and employ AI / ML models to perform corrective actions via the SMO framework 305 (such as reconfiguration via the O1 interface) or via the creation of RAN management policies (such as A1 interface policies).

[0098] As indicated above, Figure 3 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 3 The examples described are different.

[0099] Figure 4 This is a diagram illustrating example 400 of MIMO communication according to this disclosure. As shown, example 400 includes network node 402, network node 404, and network node 406. Network nodes 402 and 404 are depicted as being installed on buildings 408 and 410, respectively. In some cases, one or more of network nodes 402, 404, and / or 406 may include any number of different types of network nodes, such as, for example, base stations, relay equipment, DUs, RUs, CUs, and / or UEs, etc., and may be self-contained, integrated with any number of other different structures and / or devices, and / or installed on any number of different types of structures (e.g., vehicles, poles, and / or off-ground network equipment, etc.).

[0100] As shown in the figure, for example, network node 402 can communicate with network node 406 (e.g., UE). In some cases, for example, network node 402 may include an antenna panel configured for MIMO communication, in which case network node 402 can communicate simultaneously with network node 406 and another network node. In some cases, multiple antenna elements of the antenna panel may be configured to direct beam 412 to network node 406. Because the MIMO antenna panel includes multiple antenna elements, beam 412 can be beamformed to direct it to a target (e.g., network node 406) at a specific distance away from network node 402.

[0101] In some cases, obstacle 414 may block line-of-sight (LoS) communication 416 between network node 402 and network node 406 (as indicated by the "X" on the arrow for communication 416). To facilitate communication with network node 406, network node 402 may utilize network node 404, which may be an electromagnetic radiation reflection relay network node 404, including, for example, a radio frequency reflection array 418 configured to perform radio frequency reflection services.

[0102] Electromagnetic radiation reflection relay network node 404 can be, for example, a reconfigurable smart surface (RIS) (which may also be referred to as a smart reflective surface (IRS)). The electromagnetic radiation reflection relay network node can change the direction of reflection (e.g., guide reflection in a specific direction) and / or perform intentional refraction (e.g., using a transmissive-reflective surface). As shown, for example, network node 402 can send a signal 420 toward network node 404, which can reflect the signal 422 back to network node 406. In some cases, the reflected signal 422 can be beamformed to be specifically directed to network node 406.

[0103] like Figure 4As shown, the RF reflector array 418 may include a set of reflective elements 424 arranged adjacent to a ground plane 426. Each reflective element 424 may be coupled to a phase shifter 428, and each phase shifter 428 may be coupled to a corresponding grounding element 430. In some aspects, each reflective element 424 may be coupled to two phase shifters 428, one phase shifter for each polarization. In some aspects, one or more reflective elements 424 may be driven by a power amplifier 432. The power amplifier 432 may be coupled to a power supply 434 and may be controlled by a controller 436. In some cases, for example, the power amplifier 432 may be configured to provide just enough power to offset energy losses due to signal reflection and / or phase adjustment. In some cases, the complexity of the controller 436 and / or the power consumption of the power amplifier 432 may be based at least in part on the selection of the phase shifter 428. In some cases, the radio frequency reflector array 418 may be configured to reflect the reflected signal 422 by beamforming the reflected signal 420 to guide the reflected signal 422 based on one or more beams 438.

[0104] In some cases, low deployment costs can lead to a surge in the deployment of electromagnetic reflection relay network nodes. However, without efficient coordination among these nodes, their parallel deployment can result in interference, reduced link stability, and / or inefficient use of network resources.

[0105] Some aspects of the technology described herein may include multi-route (e.g., multi-hop) reflective relay network node strategies and associated signaling aspects for operating multiple electromagnetic reflection relay network nodes while serving a UE. In some aspects, for example, a network node may communicate with the UE through a first (e.g., primary) electromagnetic reflection relay network node and at least one additional (e.g., secondary) electromagnetic reflection relay network node. In some aspects, one or more of the at least one additional electromagnetic reflection relay network node may be directly reachable from the network node, and in some aspects, one or more of the at least one additional electromagnetic reflection relay network node may not be directly reachable from the network node. In some aspects, for example, the primary electromagnetic reflection relay network node (which may be referred to as a "secondary node" in some cases) may facilitate the discovery of at least one additional electromagnetic reflection relay network node. Electromagnetic reflection relay network nodes may be used to increase signal reception power at the UE and / or suppress interference. In some aspects, one or more secondary electromagnetic reflection relay network nodes may be used to avoid link failures (e.g., for ultra-reliable and low-latency communication (URLLC)). Therefore, some aspects can positively influence network performance.

[0106] As indicated above, Figure 4This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 4 The examples described are different.

[0107] Figure 5 This is a diagram illustrating an example 500 associated with a radio frequency reflective array having at least one antenna element according to the present disclosure. Figure 5 As shown, UE 502 and network node 504 can communicate with each other via a first electromagnetic radiation reflection relay network node (shown as "reflection network node") 506 and / or a second electromagnetic radiation reflection relay network node (shown as "reflection network node") 508. In some aspects, each of the reflection network nodes 506 and 508 may include a radio frequency reflection array having at least one antenna element. In some aspects, UE 502 may be, similar to, or include Figures 1 to 3 The UE 120 and / or depicted Figure 4 The network nodes 406 depicted, or included therein, are described. In some respects, network node 504 may be, resemble, or include... Figure 1 and Figure 2 The network node 110 described Figure 3 One or more components of the described decomposed base station architecture 300 and / or Figure 4 The network nodes 402 depicted, or included therein, may be, or be similar to, network nodes 506 and / or 508 in some respects. Figure 1 and Figure 2 The network node 110 described Figure 3 One or more components of the described decomposed base station architecture 300 and / or Figure 4 The electromagnetic radiation reflection relay network node 404 is depicted, or is included in them.

[0108] As shown in Example 500, network node 504 may communicate with UE 502 via primary communication path 510. Primary communication path 510 may include link 512 between network node 504 and electromagnetic radiation reflection relay network node 506, and link 514 between electromagnetic radiation reflection relay network node 506 (which may be referred to as the "primary electromagnetic radiation reflection relay network node" or "primary reflection network node") and UE 502. In some aspects, network node 504 may communicate with UE 502 via secondary communication path 516. Secondary communication path 516 may include link 518 between UE 502 and electromagnetic radiation reflection relay network node 508 (which may be referred to as the "primary electromagnetic radiation reflection relay network node" or "primary reflection network node"). In some aspects, secondary communication path 516 may include link 520 between electromagnetic radiation reflection relay network node 508 and electromagnetic radiation reflection relay network node 506, and link 512 between network node 504 and electromagnetic radiation reflection relay network node 506. In some other respects, the secondary communication path 516 may include a link 522 between electromagnetic radiation reflection relay network node 508 and network node 504.

[0109] In some aspects, for example, network node 504 can communicate with UE 502 via electromagnetic reflection relay network node 506. Network node 504 can reconfigure electromagnetic reflection relay network node 506 to transmit synchronization signal blocks (SSBs) associated with electromagnetic reflection relay network node 506 in order to find additional electromagnetic reflection relay network nodes that can utilize its currently active link 510 to assist electromagnetic reflection relay network node 506.

[0110] For example, as indicated by reference numeral 524, network node 504 can provide, and electromagnetic reflection relay network node 506 can obtain, configuration information that configures the first electromagnetic reflection relay network node 506 to transmit at least one synchronization signal block (SSB) associated with the first electromagnetic reflection relay network node 506. In some aspects, the configuration information indicates a time grating 526 for the timing transmission of the at least one SSB. In some aspects, network node 504 can (e.g., via control signals) transmit an indication of the time grating 526. As shown, for example, the time grating 526 can indicate, for each time slot (e.g., indicated as "time slot 1" and "time slot 2"), one or more sets 528 of symbols 530 to be transmitted to or from UE 502 during its period and one or more sets 532 of symbols 530 to be transmitted by the electromagnetic reflection relay network node 506 during its period. As shown by reference numeral 534 in the attached figure, electromagnetic radiation reflection relay network node 506 may send an SSB to facilitate the discovery of one or more additional electromagnetic radiation reflection relay network nodes (e.g., electromagnetic radiation reflection relay network node 508).

[0111] If network node 504 finds an additional electromagnetic reflection relay node (e.g., electromagnetic reflection relay node 508) via electromagnetic reflection relay node 506, network node 504 can reconfigure electromagnetic reflection relay node 506 with a suitable phase matrix, different from the phase matrix used to serve UE 502 only via electromagnetic reflection relay node 506. For example, as shown by reference numeral 536, electromagnetic reflection relay node 506 can communicate with UE 502 only via the main communication path 510 associated with a first phase matrix during an initial time period, which is associated with electromagnetic reflection relay node 506. As shown by reference numeral 538, network node 504 can provide, and electromagnetic reflection relay node 506 can obtain, configuration information indicating the main phase matrix used to communicate with UE 502 during the time period when electromagnetic reflection relay node 508 also communicates with UE 502.

[0112] Therefore, for example, when network node 504 sends data to UE 502, the data can be sent to electromagnetic reflection relay network node 506, which can then send the data to UE 502 and electromagnetic reflection relay network node 508 (which can also send data to UE 502). In this way, secondary communication path 516 can be used to assist primary communication path 510. In some aspects, secondary communication path 516 can be used to reduce interference to signals sent from network node 504 to UE 502 and / or increase the received power of signals sent from that network node to the UE. In some aspects, communication from UE 502 to network node 504 can also benefit from secondary communication path 516 in a similar manner. For example, secondary communication path 516 can be used to reduce interference to primary communication path 510, compensate for interference to primary communication path 510, and / or increase the received power at network node 504.

[0113] In some aspects, network node 504 can configure the phase matrix of electromagnetic radiation reflection relay network node 506 to generate a multi-lobed or wide-beam pattern to serve UE 502 via primary communication path 510 using link 514 and auxiliary link 518. In some aspects, any number of multi-hop node search algorithms (e.g., using upper layers) and their signaling mechanisms can be implemented in conjunction with the auxiliary communication path techniques described above, while building path redundancy for robustness (e.g., to mitigate link failures), which may also be useful in vehicle-to-X (V2X) applications (e.g., for cluster formation). As indicated by reference numeral 540, electromagnetic radiation reflection relay network node 506 can communicate with UE 502 using the primary phase matrix.

[0114] As indicated above, in some aspects, electromagnetic radiation reflection relay network node 506 may communicate via main communication path 510 with at least one of the following: a wide-beam radiation mode associated with electromagnetic radiation reflection relay network node 506 or a multi-lobed radiation mode associated with electromagnetic radiation reflection relay network node 506. In some aspects, electromagnetic radiation reflection relay network node 506 and / or electromagnetic radiation reflection relay network node 508 may communicate via secondary communication path 516 with at least one of the following: a wide-beam radiation mode associated with electromagnetic radiation reflection relay network node 506 or a multi-lobed radiation mode associated with electromagnetic radiation reflection relay network node 506.

[0115] In some aspects, network node 504 may communicate with UE 502 via a primary communication path 510, associated with a first power level of electromagnetic reflection relay network node 506 and a second power level of electromagnetic reflection relay network node 508. In some aspects, the second power level may be higher than the first power level. In this way, for example, network node 504 may preferably use a primary reflection network node beam pattern that directs less power toward link 514 between electromagnetic reflection relay network node 506 and UE 502 to reduce interference to the area surrounding link 514. In some aspects, network node 504 may configure electromagnetic reflection relay network node 506 to serve UE 502 only via secondary communication path 516 to further suppress interference caused by the first communication path 510.

[0116] In some aspects, network node 504 may find more than one electromagnetic reflection relay network node that can be configured to serve UE 502. In some aspects, network node 504 may use electromagnetic reflection relay network nodes to multiplex UE data (e.g., via spatial division multiplexing (SDM), time division duplex (TDD), and / or frequency division multiplexing (FDM)) and / or operate to form a primary communication path and a secondary communication path for robust operation (e.g., to mitigate link failures and / or minimize latency to support URLLC schemes). For example, in some aspects, network node 504 may communicate via secondary communication path 516 in association with URLLC schemes and / or link failure prediction.

[0117] In some aspects, network node 504 may select the electromagnetic radiation reflection relay network node that provides the highest received power and / or the least interference to the set of spatial directions of interest at UE 502. In some aspects, for example, network node 504 may utilize the found electromagnetic radiation reflection relay network node based on received power (at UE 502) or multiplexing gain being greater than a threshold or interference (to one or more directions of interest) being less than a threshold. In some aspects, network node 504 may utilize the electromagnetic radiation reflection relay network node to achieve multiplexing gain via multiplexing techniques such as SDM (e.g., if independent beams can be assigned to each electromagnetic radiation reflection relay network node at network node 504). If independent beams are not assigned or cannot be assigned to each electromagnetic radiation reflection relay network node at network node 504, network node 504 may use TDD and / or FDM. For example, in some aspects, TDD may be used when two or more electromagnetic radiation reflection relay network nodes have the same frequency band, while FDM may be used when the frequency bands are different.

[0118] For example, in some aspects, communication via secondary communication path 516 between network node 504 and / or electromagnetic radiation reflection relay network node 506 includes: communicating according to a spatial division multiplexing scheme in which a first beam is associated with a first electromagnetic radiation reflection relay network node and a second beam is associated with a second electromagnetic radiation reflection relay network node. In some aspects, network node 504 and / or electromagnetic radiation reflection relay network node 506 may communicate via secondary communication path 516 according to a time division multiplexing scheme (e.g., TDD) based on the association of electromagnetic radiation reflection relay network node 506 and electromagnetic radiation reflection relay network node 508 with a common frequency band. In some aspects, network node 504 and / or electromagnetic radiation reflection relay network node 506 may communicate via secondary communication path 516 according to an FDM scheme based on the association of electromagnetic radiation reflection relay network node 506 with a first frequency band and electromagnetic radiation reflection relay network node 508 with a different second frequency band. In some aspects, network node 504 and / or electromagnetic radiation reflection relay network node 506 may communicate via secondary communication path 516 in association with low-latency communication schemes (e.g., URLLC schemes). In some aspects, network node 504 and / or electromagnetic radiation reflection relay network node 506 may communicate via secondary communication path 516 in association with link failure prediction.

[0119] In some aspects, for example, UE 502 can provide, and electromagnetic reflection relay network node 506 can obtain, channel state information (CSI) indicating a first value of channel parameters associated with link 518 between UE 502 and electromagnetic reflection relay network node 508, and a second value of channel parameters associated with link 542 between UE 502 and third electromagnetic reflection relay network node 544. Network node 504 and electromagnetic reflection relay network node 506 can communicate via secondary communication path 516 based on link conditions satisfied by the CSI. In some aspects, the channel parameters include at least one of the following: received power at UE 502, multiplexing gain at UE 502, or interference level at UE 502. In some aspects, the CSI can satisfy a channel parameter threshold based on a first value to satisfy the link conditions. In some aspects, the CSI can satisfy the link conditions based on a first value being greater than a second value. In some respects, network node 504 may communicate with UE 502 via a third communication path (e.g., an additional secondary communication path), which includes link 542 as a supplement or alternative to secondary communication path 516.

[0120] In some aspects, network node 504 may designate electromagnetic radiation reflection relay network node 506 as the primary electromagnetic radiation reflection relay network node and electromagnetic radiation reflection relay network node 508 as the secondary electromagnetic radiation reflection relay network node. In some aspects, network node 504 may utilize only the secondary electromagnetic radiation reflection relay network node in the event of a failure of the primary communication path 510. In some aspects, network node 504 may keep the secondary electromagnetic radiation reflection relay network node occupied (e.g., in a state preventing its utilization by other network nodes) for use in the event of a failure of the primary communication path 510. In some aspects, network node 504 may keep the secondary electromagnetic radiation reflection relay network node occupied based on whether the communication with UE 502 is URLLC communication and / or based on link failure prediction. In this way, some aspects can facilitate the availability of electromagnetic radiation reflection relay network nodes for secondary communication paths without introducing unnecessary network inefficiencies by occupying electromagnetic radiation reflection relay network nodes without using them (except in certain scenarios). In some aspects, network node 504 may keep the secondary electromagnetic radiation reflection relay network node occupied only for a defined amount of time (e.g., within a predetermined number of symbols, time slots, or frames). In some aspects, network node 504 may provide other network nodes with an indication of the defined amount of time, allowing other network nodes to attempt to use unoccupied time resources associated with the electromagnetic radiation reflection relay network node. In some aspects, a time raster may be used to dynamically (e.g., using download control information) or semi-statically (e.g., using RRC messages) indicate occupied (and / or unoccupied) time resources. In some aspects, network node 504 (and / or any other network node controlling the secondary electromagnetic radiation reflection relay network node) may notify the network of start and / or stop times associated with the use of the electromagnetic radiation reflection relay network node, start and / or stop times associated with the selection process for selecting the secondary electromagnetic radiation reflection relay network node, and / or start and / or start times associated with using the electromagnetic radiation reflection relay network node as the primary electromagnetic radiation reflection relay network node.

[0121] In some aspects, for example, network node 504 and / or electromagnetic radiation reflection relay network node 506 may communicate via secondary communication path 516 in association with a time resource set. This time resource set may include at least one of symbols, time slots, or frames. In some aspects, network node 504 and / or electromagnetic radiation reflection relay network node 506 may send communications indicating the time resource set. This communication may include at least one of RRC messages or dynamic control communications. In some aspects, network node 504 and / or electromagnetic radiation reflection relay network node 506 may send communications to at least one additional network node. In some aspects, network node 504 and / or electromagnetic radiation reflection relay network node 506 may receive from at least one additional network node an indication of a selection window associated with at least one additional electromagnetic radiation reflection relay network node.

[0122] In some aspects, network node 504 and / or electromagnetic radiation reflection relay network node 506 receive from at least one additional network node an instruction to designate electromagnetic radiation reflection relay network node 508 as the primary electromagnetic radiation reflection relay network node associated with at least one additional network node. Network node 504 and / or electromagnetic radiation reflection relay network node 506 may provide at least one additional network node with an instruction to a selection window associated with at least one additional electromagnetic radiation reflection relay network node. In some aspects, network node 504 and / or electromagnetic radiation reflection relay network node 506 may provide at least one additional network node with an instruction to designate a second electromagnetic radiation reflection relay network node as the primary electromagnetic radiation reflection relay network node associated with that network node.

[0123] As indicated above, Figure 5 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 5 The examples described are different.

[0124] Figure 6 This is a diagram illustrating an example procedure 600 performed by a UE according to this disclosure. Example procedure 600 is an example of an operation performed by a UE (e.g., UE 502) associated with the operation of a multi-electromagnetic radiation reflection relay network node.

[0125] like Figure 6 As shown, in some aspects, process 600 may include: communicating with a network node via a main communication path over a period of time, the main communication path including a link between the network node and a first electromagnetic radiation reflection relay network node and a link between the first electromagnetic radiation reflection relay network node and the UE (block 610). For example, the UE (e.g., using...) Figure 10The described receiving component 1002, transmitting component 1004, and / or communication manager 1006 can communicate with network nodes via a main communication path for a period of time. This main communication path includes a link between the network node and a first electromagnetic radiation reflection relay network node and a link between the first electromagnetic radiation reflection relay network node and the UE, as described above.

[0126] like Figure 6 Further shown, in some aspects, process 600 may include: communicating with the network node via at least one secondary communication path during the time period, the at least one secondary communication path including a link between the UE and a second electromagnetic radiation reflection relay network node (box 620). For example, the UE (e.g., using...) Figure 10 The described receiving component 1002, transmitting component 1004 and / or communication manager 1006 can communicate with the network node via at least one secondary communication path during the time period, the at least one secondary communication path including the link between the UE and the second electromagnetic radiation reflection relay network node, as described above.

[0127] Process 600 may include additional aspects, such as any single aspect or any combination of aspects described below and / or in conjunction with one or more other processes described elsewhere in this document.

[0128] In a first aspect, the at least one auxiliary communication path further includes a link between the second electromagnetic radiation reflection relay network node and the first electromagnetic radiation reflection relay network node, and a link between the first electromagnetic radiation reflection relay network node and the network node.

[0129] In a second aspect, communication via the main communication path, either alone or in combination with the first aspect, includes: transmitting data associated with a primary phase matrix, which is associated with the first electromagnetic radiation reflection relay network node; and communication via the at least one secondary communication path includes: transmitting the data associated with at least one secondary phase matrix, which is associated with at least one of the following: the second electromagnetic radiation reflection relay network node or at least one additional electromagnetic radiation reflection relay network node. In a third aspect, communication via the main communication path, either alone or in combination with one or more of the first and second aspects, includes communicating in association with at least one of the following: a wide-beam radiation mode associated with the first electromagnetic radiation reflection relay network node or a multi-lobe radiation mode associated with the first electromagnetic radiation reflection relay network node. In the fourth aspect, communication via the at least one auxiliary communication path, either alone or in combination with one or more of the first to third aspects, includes communication associated with at least one of the following: a wide-beam radiation mode associated with the first electromagnetic radiation reflection relay network node or a multi-lobe radiation mode associated with the first electromagnetic radiation reflection relay network node.
