[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This patent application claims priority to U.S. Provisional Patent Application No. 62 / 993,447, filed on March 23, 2020, entitled “ACCESS PROCEDURE CONFIGURATION OF A MILLIMETER WAVE REPEATER,” and U.S. Non-Provisional Patent Application No. 17 / 188,944, filed on March 1, 2021, entitled “ACCESS PROCEDURE CONFIGURATION OF A MILLIMETER WAVE REPEATER,” which are hereby expressly incorporated herein by reference. Technical Field

[0003] Aspects of the present disclosure relate generally to wireless communications and techniques and apparatus for access procedure configuration for millimeter wave (mmW) repeaters. Background Art

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

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

[0006] The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different user devices to communicate at municipal, national, regional and even global levels. NR (which may also be referred to as 5G) is a collection of enhancements to the LTE mobile standard promulgated by 3GPP. NR is designed to better support mobile broadband Internet access by improving spectrum efficiency, reducing costs, improving services, utilizing new spectrum, and using orthogonal frequency division multiplexing (OFDM) (CP-OFDM) with cyclic prefix (CP) on the downlink (DL), using CP-OFDM and / or SC-FDM (e.g., also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink (UL) to better integrate with other open standards, as well as supporting beamforming, multiple input multiple output (MIMO) antenna technology and carrier aggregation. As the demand for mobile broadband access continues to increase, further improvements to LTE, NR and other radio access technologies remain useful. Summary of the invention

[0011] In some aspects, a non-transitory computer-readable medium may store one or more instructions for wireless communication. The one or more instructions, when executed by one or more processors of a repeater, may cause the one or more processors to receive configuration information associated with configuring the repeater's participation in an access procedure; receive a signal associated with the access procedure from a first wireless communication device; and forward the signal associated with the access procedure to a second wireless communication device based at least in part on the configuration information and other information associated with the access procedure received by the repeater.

[0012] In some aspects, a non-transitory computer-readable medium may store one or more instructions for wireless communication.

[0030] The various aspects of the present disclosure are described more fully below with reference to the accompanying drawings. However, the present disclosure can be implemented in many different forms and should not be interpreted as being limited to any specific structure or function presented throughout the present disclosure. Instead, these aspects are provided so that the present disclosure will be thorough and complete, and the scope of the present disclosure will be fully conveyed to those skilled in the art. Based on the teachings of this article, it should be understood by those skilled in the art that the scope of the present disclosure is intended to cover any aspect of the present disclosure disclosed herein, whether it is implemented independently of any other aspect of the present disclosure or implemented in combination with them. For example, any number of aspects set forth herein can be used to implement a device or practice method. In addition, the scope of the present disclosure is intended to cover such a device or method, which is practiced using other structures, functions, or structures and functions other than or different from the various aspects of the present disclosure set forth herein. It should be understood that any aspect of the present disclosure disclosed herein can be embodied by one or more elements of the claims.

[0031] Several aspects of telecommunication systems will now be presented with reference to various devices and techniques. These devices and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements can be implemented using hardware, software, or a combination thereof. Whether these elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0032] It should be noted that although various aspects may be described herein using terminology generally associated with 5G or NR radio access technologies (RATs), various aspects of the present disclosure may be applied to other RATs, such as 3G RATs, 4G RATs, and / or post-5G (e.g., 6G) RATs.

[0033] Figure 1 is a diagram showing an example of a wireless network 100 according to the present disclosure. Among other examples, the wireless network 100 may be or may include elements of a 5G (NR) network and / or an LTE network. The wireless network 100 may include a plurality of base stations 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d) and other network entities. A base station (BS) is an entity that communicates with a user equipment (UE) and may also be referred to as an NR BS, Node B, gNB, 5G node B (NB), access point, transmit receive point (TRP), etc. Each BS may provide communication coverage for a specific geographic area. In 3GPP, the term "cell" may refer to a coverage area of ​​a BS and / or a BS subsystem serving the coverage area, depending on the context in which the term is used.

[0034] A BS may provide communication coverage for a macro cell, a pico cell, a femto cell, and / or another type of cell. A macro cell may cover a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access to UEs with service subscriptions. A pico cell may cover a relatively small geographic area and may allow unrestricted access to UEs with service subscriptions. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access to UEs associated with the femto cell (e.g., UEs in a closed subscriber group (CSG)). A BS for a macro cell may be referred to as a macro BS. A BS for a pico cell may be referred to as a pico BS. A BS for a femto cell may be referred to as a femto BS or a home BS. In Figure 1 In the example shown in , BS 110a may be a macro BS for macro cell 102a, BS 110b may be a pico BS for pico cell 102b, and BS 110c may be a femto BS for femto cell 102c. A BS may support one or more (e.g., three) cells. The terms "eNB", "base station", "NR BS", "gNB", "TRP", "AP", "node B", "5GNB", and "cell" may be used interchangeably herein.

[0035] In some aspects, the cells are not necessarily stationary, and the geographic area of ​​the cells may move according to the location of the mobile BS. In some aspects, the BSs may be interconnected with each other and / or with one or more other BSs or network nodes (not shown) in the wireless network 100 through various types of backhaul interfaces (such as direct physical connections or virtual networks) using any suitable transport network.

[0036] The wireless network 100 may also include a relay station. A relay station is an entity that can receive data transmissions from an upstream station (e.g., a BS or a UE) and send data transmissions to a downstream station (e.g., a UE or a BS). A relay station may also be a UE that can relay transmissions for other UEs. Figure 1 In the example shown in FIG. 1 , a relay BS 110 d may communicate with a macro BS 110 a and a UE 120 d to facilitate communication between the BS 110 a and the UE 120 d. A relay BS may also be referred to as a relay station, a relay base station, a relay, or the like.

[0037] The wireless network 100 may be a heterogeneous network including different types of BSs, such as a macro BS, a pico BS, a femto BS, a relay BS, etc. These different types of BSs may have different transmit power levels, different coverage areas, and different effects on interference in the wireless network 100. For example, a macro BS may have a high transmit power level (e.g., 5 to 40 watts), while a pico BS, a femto BS, and a relay BS may have a lower transmit power level (e.g., 0.1 to 2 watts).

[0038] A network controller 130 may be coupled to a set of BSs and may provide coordination and control for these BSs. The network controller 130 may communicate with the BSs via a backhaul. The BSs may also communicate with each other directly or indirectly, for example, via a wireless or wired backhaul.

[0039] UE 120 (e.g., 120a, 120b, 120c) can be dispersed throughout the wireless network 100, and each UE can be stationary or mobile. UE can also be referred to as an access terminal, terminal, mobile station, subscriber unit, station, etc. 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, a cordless phone, a wireless local loop (WLL) station, a tablet, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device or equipment, a biometric sensor / device, a wearable device (smart watch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet)), an entertainment device (e.g., a music or video device, or a satellite radio), a vehicle component or sensor, a smart meter / sensor, an industrial manufacturing equipment, a global positioning system device, or any other suitable device configured to communicate via a wireless or wired medium.

[0040] Some UEs may be considered as 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, which may communicate with a base station, another device (e.g., a remote device) or some other entity. For example, a wireless node may provide a connection to a network (e.g., a wide area network, such as the Internet or a cellular network) or provide a connection to a network via a wired or wireless communication link. Some UEs may be considered as Internet of Things (IoT) devices, and / or may be implemented as NB-IoT (narrowband Internet of Things) devices. Some UEs may be considered as customer premises equipment (CPE). UE 120 may be included in a housing that houses components of UE 120 (such as a processor component and / or a memory component). In some aspects, the processor component and the memory component may be coupled together. For example, a processor component (e.g., one or more processors) and a memory component (e.g., a memory) may be operably coupled, communicatively coupled, electronically coupled and / or electrically coupled.

[0041] Generally, any number of wireless networks can be deployed in a given geographic area. Each wireless network can support a specific RAT and can operate on one or more frequencies. RAT can also be referred to as radio technology, air interface, etc. Frequency can also be referred to as carrier, frequency channel, etc. Each frequency can support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks can be deployed.

[0042] In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) can communicate directly (e.g., without using base station 110 as an intermediary for communicating with each other) using one or more side link channels. For example, UE 120 can communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocol (e.g., which may include vehicle-to-vehicle (V2V) protocol or vehicle-to-infrastructure (V2I) protocol) and / or mesh network. In this case, UE 120 can perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by base station 110.

[0043] In some aspects, a millimeter wave (mmW) repeater 140 (sometimes referred to herein as repeater 140) can receive an analog mmW signal from a base station 110, can amplify the analog mmW signal, and can send the amplified mmW signal to one or more UEs 120 (e.g., shown as UE 120f). In some aspects, the mmW repeater 140 can be an analog mmW repeater, sometimes also referred to as a layer 1 mmW repeater. Additionally or alternatively, the mmW repeater 140 can be a wireless TRP acting as a distributed unit (e.g., a 5G access node) that communicates wirelessly with a base station 110 acting as a central unit or access node controller (e.g., a 5G access node). The mmW repeater can receive, amplify, and send analog mmW signals without performing analog-to-digital conversion of the analog mmW signal and / or without performing any digital signal processing on the mmW signal. In this way, latency can be reduced and the cost of producing the mmW repeater 140 can be reduced. Additional details about the mmW repeater 140 are provided elsewhere herein.

[0044] In some aspects, the base station 110 may determine configuration information associated with configuring the mmW repeater 140 to participate in forwarding signals in an access procedure, and may send configuration information associated with configuring the mmW repeater 140 to participate in the access procedure, as described herein. In some aspects, the mmW repeater 140 may receive configuration information associated with configuring the mmW repeater 140 to participate in the access procedure, and may receive and forward signals associated with the access procedure based at least in part on the configuration information, as described herein.

[0045] Devices of the wireless network 100 may communicate using an electromagnetic spectrum, which may be subdivided into various categories, bands, channels, etc. based on frequency or wavelength. For example, devices of the wireless network 100 may communicate using an operating band having a first frequency range (FR1) (which may span from 410 MHz to 7.125 GHz), and / or may communicate using an operating band having a second frequency range (FR2) (which may span from 24.25 GHz to 52.6 GHz). Frequencies between FR1 and FR2 are typically referred to as mid-band frequencies. Although a portion of FR1 is greater than 6 GHz, FR1 is typically referred to as a "sub-6 GHz" band. Similarly, FR2 is typically referred to as a "millimeter wave" band, although it is different from the extremely high frequency (EHF) band (30 GHz–300 GHz) identified by the International Telecommunication Union (ITU) as a "millimeter wave" band. Therefore, unless otherwise specifically stated, it should be understood that the terms "sub-6 GHz", etc., if used herein, can broadly refer to frequencies less than 6 GHz, frequencies within FR1, and / or mid-band frequencies (e.g., greater than 7.125 GHz). Similarly, unless otherwise specifically stated, it should be understood that the terms "millimeter wave", etc., if used herein, can broadly refer to frequencies within the EHF band, frequencies within FR2, and / or mid-band frequencies (e.g., less than 24.25 GHz). It is contemplated that the frequencies included in FR1 and FR2 can be modified, and the techniques described herein are applicable to these modified frequency ranges.

[0046] As mentioned above, providing Figure 1 As an example. Other examples can be related to Figure 1 Different than described.

[0047] Figure 2 is a diagram illustrating an example 200 of base station 110 communicating with UE 120 in wireless network 100 according to the present disclosure. Base station 110 may be equipped with T antennas 234a through 234t, and UE 120 may be equipped with R antennas 252a through 252r, where in general T≥1 and R≥1.

[0048] At the base station 110, the transmit processor 220 may receive data for one or more UEs from the data source 212, select one or more modulation and coding schemes (MCS) for each UE based at least in part on a channel quality indicator (CQI) received from the UE, process (e.g., encode and modulate) data for the UE based at least in part on the (multiple) MCS selected for each UE, and provide data symbols for all UEs. The transmit processor 220 may also process system information (e.g., for semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper layer signaling), and provide overhead symbols and control symbols. The transmit processor 220 may also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signals (PSS) or secondary synchronization signals (SSS)). A transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, if applicable, and may provide T output symbol streams to T modulators (MOD) 232a through 232t. Each modulator 232 may process a corresponding output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modulator 232 may further process (e.g., convert to analog, amplify, filter, and up-convert) the output sample stream to obtain a downlink signal. The T downlink signals from modulators 232a through 232t may be transmitted via T antennas 234a through 234t, respectively.

[0049] At the UE 120, antennas 252a to 252r may receive downlink signals from the base station 110 and / or other base stations, and may provide received signals to demodulators (DEMODs) 254a to 254r, respectively. Each demodulator 254 may condition (e.g., filter, amplify, downconvert, and digitize) the received signal to obtain input samples. Each demodulator 254 may further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector 256 may obtain received symbols from all R demodulators 254a to 254r, perform MIMO detection on the received symbols (if applicable), and provide detected symbols. A receive processor 258 may process (e.g., demodulate and decode) the detected symbols, provide decoded data for 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" may refer to one or more controllers, one or more processors, or a combination thereof. The channel processor may determine a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, and / or a CQI) parameter, etc. In some aspects, one or more components of the UE 120 may be included in the housing 284.

[0050] The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292. The network controller 130 may include, for example, one or more devices in a core network. The network controller 130 may communicate with the base station 110 via the communication unit 294.

[0051] Antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include, or may be included within, one or more antenna panels, antenna groups, antenna element sets, and / or antenna arrays, etc. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include one or more antenna elements. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include coplanar antenna element sets and / or non-coplanar antenna element sets. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include antenna elements within a single housing and / or antenna elements within multiple housings. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include one or more antenna elements coupled to one or more transmit and / or receive components, such as Figure 2 One or more components of a

[0052] On the uplink, at the UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information from a controller / processor 280 (e.g., for reports including RSRP, RSSI, RSRQ, and / or CQI). The transmit processor 264 may also generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be precoded by a TX MIMO processor 266 (if applicable), further processed by modulators 254a through 254r (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to the base station 110. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 254) of the UE 120 may be included in a modem of the UE 120. In some aspects, the UE 120 includes a transceiver. The transceiver may include any combination of antenna(s) 252, modulators and / or demodulators 254, MIMO detectors 256, receive processors 258, transmit processors 264, and / or TX MIMO processors 266. The transceiver may be used by a processor (e.g., controller / processor 280) and memory 282 to perform aspects of any of the methods described herein, for example, as described with reference to Figure 6-Figure 8 described.

[0053] At the base station 110, uplink signals from the UE 120 and other UEs may be received by the antenna 234, processed by the demodulator 232, detected by the MIMO detector 236 (if applicable), and further processed by the receive processor 238 to obtain decoded data and control information sent by the UE 120. The receive processor 238 may provide the decoded data to the data sink 239 and the decoded control information to the controller / processor 240. The base station 110 may include a communication unit 244 and communicate with the network controller 130 via the communication unit 244. The base station 110 may include a scheduler 246 to schedule the UE 120 for downlink and / or uplink communications. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 232) of the base station 110 may be included in a modem of the base station 110. In some aspects, the base station 110 includes a transceiver. The transceiver may include any combination of antenna(s) 234, modulators and / or demodulators 232, MIMO detectors 236, receive processors 238, transmit processors 220, and / or TX MIMO processors 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to perform aspects of any of the methods described herein, for example, as described with reference to Figure 6-Figure 8 described.

[0054] The controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other (multiple) components of the base station 110 may perform one or more techniques associated with the access procedure configuration of the mmW relay, as described in more detail elsewhere herein. For example, the controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component(s) of may perform or direct e.g. Figure 8 800 and / or other processes described herein. Memories 242 and 282 may store data and program codes for base station 110 and UE 120, respectively. In some aspects, memory 242 and / or memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, the one or more instructions, when executed by one or more processors of base station 110 and / or UE 120 (e.g., directly, or after compilation, conversion, and / or interpretation), may cause one or more processors, UE 120, and / or base station 110 to perform or direct, for example, Figure 8 The operations of process 800 and / or other processes described herein. In some aspects, executing instructions may include running instructions, converting instructions, compiling instructions, and / or interpreting instructions, etc.

[0055] In some aspects, the base station 110 may include a component for determining configuration information associated with configuring the mmW repeater 140 to participate in forwarding a signal received from a first wireless communication device (e.g., the base station 110, the UE 120, etc.) to a second wireless communication device (e.g., the UE 120, the base station 110, etc.) during an access procedure; and a component for sending the configuration information associated with configuring the mmW repeater 140 to participate in the access procedure and other information associated with the access procedure to the repeater; etc. In some aspects, such a component may include a component for configuring the mmW repeater 140 to participate in the access procedure in conjunction with the base station 110. Figure 2 One or more components of base station 110 are depicted, such as antenna 234, DEMOD 232, MIMO detector 236, receive processor 238, controller / processor 240, transmit processor 220, TX MIMO processor 230, MOD 232, antenna 234, and the like.

[0056] Although Figure 2 The blocks in the 200 and 210 are shown as distinct components, but the functionality described above with respect to the blocks may be implemented in a single hardware, software, or combined component or various combinations of components. For example, the functionality described with respect to the transmit processor 264, the receive processor 258, and / or the TX MIMO processor 266 may be performed by or under the control of the controller / processor 280.

[0057] As mentioned above, providing Figure 2As an example. Other examples can be related to Figure 2 Different than described.

[0058] Figure 3 is a diagram illustrating an example 300 of a radio access network according to the present disclosure.

[0059] As shown by reference numeral 305, a conventional (e.g., 3G, 4G, LTE, etc.) radio access network may include multiple base stations 310 (e.g., access nodes (ANs)), each of which communicates with a core network via a wired backhaul link 315 (such as a fiber optic connection). The base stations 310 may communicate with UEs 320 via access links 325 (which may be wireless links). In some aspects, Figure 3 The base station 310 shown in FIG. 3 may correspond to Figure 1 Similarly, Figure 3 The UE 320 shown in FIG. 3 may correspond to Figure 1 UE 120 shown in .

[0060] As shown in the reference numeral 330, the radio access network may include a wireless backhaul network, sometimes referred to as an integrated access and backhaul (IAB) network. In an IAB network, at least one base station is an anchor base station 335 that communicates with a core network via a wired backhaul link 340 (such as a fiber optic connection). The anchor base station 335 may also be referred to as an IAB donor (or IAB-donor). The IAB network may include one or more non-anchor base stations 345, sometimes referred to as relay base stations or IAB nodes (or IAB-nodes). The non-anchor base station 345 may communicate directly or indirectly (e.g., via one or more non-anchor base stations 345) with the anchor base station 335 via one or more backhaul links 350 to form a backhaul path to the core network for carrying backhaul traffic. The backhaul link 350 may be a wireless link. The anchor base station(s) 335 and / or the non-anchor base station(s) 345 may communicate with one or more UEs 355 via an access link 360 (which may be a wireless link for carrying access traffic). In some aspects, Figure 3 The anchor base station 335 and / or the non-anchor base station 345 shown in FIG. 3 may correspond to Figure 1 Similarly, Figure 3 The UE 355 shown in FIG. 3 may correspond to Figure 1 UE 120 shown in .

[0061] As shown in the reference numeral 365, in some aspects, the radio access network including the IAB network can utilize millimeter wave technology and / or directional communication (e.g., beamforming, precoding, etc.) for communication between base stations and / or UEs (e.g., between two base stations, between two UEs, and / or between a base station and a UE). For example, a wireless backhaul link 370 between base stations can use millimeter waves to carry information and / or can be directed toward a target base station using beamforming, precoding, etc. Similarly, a wireless access link 375 between a UE and a base station can use millimeter waves and / or can be directed toward a target wireless node (e.g., a UE and / or a base station). In this way, inter-link interference can be reduced.

[0062] In some aspects, the IAB network may support multi-hop wireless backhaul. Additionally or alternatively, the nodes of the IAB network may use the same radio access technology (e.g., 5G / NR). Additionally or alternatively, the nodes of the IAB network may share resources for access links and backhaul links, such as time resources, frequency resources, space resources, etc. In addition, various architectures of IAB nodes and / or IAB donors may be supported.

[0063] Figure 3 The configuration of the base station and UE in is shown as an example, and other examples are considered. For example, Figure 3 The one or more base stations shown in the figure may be replaced by one or more UEs communicating via a UE-to-UE access network (e.g., a peer-to-peer network, a device-to-device network, etc.). In this case, the anchor node may refer to a UE that directly communicates with a base station (e.g., an anchor base station or a non-anchor base station).

[0064] As shown above, provide Figure 3 As an example. Other examples can be related to Figure 3 Different than described.

[0065] Figure 4 is a diagram illustrating an example 400 of communicating using an analog millimeter wave repeater according to the present disclosure.

[0066] Because millimeter wave communications have higher frequencies and shorter wavelengths than other types of radio waves used for communication (e.g., communications below 6 GHz), millimeter wave communications can have shorter propagation distances and can be more easily blocked by obstacles than other types of radio waves. For example, wireless communications using radio waves below 6 GHz may be able to penetrate the walls of a building or structure to provide coverage to an area on the opposite side of the wall from a base station 110 that communicates using radio waves below 6 GHz. However, millimeter waves may not be able to penetrate the same wall (e.g., depending on the thickness of the wall, the material that makes up the wall, etc.). Some techniques and devices described herein use millimeter wave repeaters 140 to increase the coverage area of ​​a base station 110 to expand coverage to a UE 120 in the absence of a line of sight to the base station 110 (e.g., due to an obstacle), etc. In addition, the millimeter wave repeater 140 described herein may be a layer 1 or analog millimeter wave repeater, which is associated with lower costs, less processing, and lower latency than a layer 2 or layer 3 repeater.

[0067] like Figure 4 As shown in , the millimeter wave repeater 140 can perform directional communication by using beamforming to communicate with the base station 110 via a first beam (e.g., a backhaul beam on a backhaul link with the base station 110) and communicate with the UE 120 via a second beam (e.g., an access beam on an access link with the UE 120). In order to achieve a long propagation distance and / or meet a required link budget, the millimeter wave repeater can use a narrow beam (e.g., a beam width less than a threshold) for such communication.

[0068] However, compared to wider beams, using narrower beams requires the use of more resources of the millimeter wave repeater 140 (e.g., processing resources, memory resources, power, battery power, etc.) and more network resources (e.g., time resources, frequency resources, space resources, etc.) to perform beam training (e.g., to determine a suitable beam), beam maintenance (e.g., to find a suitable beam when conditions change due to mobility, etc.), beam management, etc. Compared to using wider beams, this may waste resources of the millimeter wave repeater 140 and / or network resources, and may result in increased production costs for the millimeter wave repeater 140, which may be widely deployed throughout the radio access network.

[0069] For example, the millimeter wave repeater 140 may be deployed in a fixed location with limited or no mobility, similar to the base station 110. Figure 4As shown in , due to the limited or no mobility of the base station 110 and the millimeter wave repeater 140 (and / or due to the line-of-sight communication path between the base station 110 and the millimeter wave repeater 140), because the need for beam training, beam maintenance and / or beam management may be limited, the millimeter wave repeater 140 can use a narrower beam to communicate with the base station 110 without unnecessarily consuming network resources and / or resources of the millimeter wave repeater 140.

[0070] like Figure 4 As further shown in , the millimeter wave repeater 140 can use a wider beam (e.g., a pseudo-omnidirectional beam, etc.) to communicate with one or more UEs 120. The wider beam can provide wider coverage for the access link, thereby providing coverage to the mobile UE 120 without the need for frequent beam training, beam maintenance and / or beam management. In this way, network resources and / or resources of the millimeter wave repeater 140 can be saved. In addition, if the millimeter wave repeater 140 does not include digital signal processing capabilities, resources of the base station 110 (e.g., processing resources, memory resources, etc.) that would otherwise be used to perform such signal processing for the millimeter wave repeater 140 can be saved, and network resources that would otherwise be used to communicate between the base station 110 and the millimeter wave repeater 140 to the input of such processing or the output of such processing can be saved.

[0071] In this manner, mmWave repeater 140 may increase coverage area, provide access around obstacles (as shown), etc., while conserving resources of base station 110 , resources of mmWave repeater 140 , network resources, etc. Additional details are described below.

[0072] As shown above, provide Figure 4 As an example. Other examples can be related to Figure 4 Different than described.

[0073] Figure 5A and Figure 5B is a diagram illustrating an example of a millimeter wave repeater 500 according to the present disclosure. In some aspects, the millimeter wave repeater 500 may correspond to Figure 1 The millimeter wave repeater 140 shown in FIG.

[0074] like Figure 5A As shown in , in some aspects, the millimeter wave repeater 500 may include one or more phased array antennas 510-1 to 510-N (N≥1), a gain component 520, a controller 530, a communication component 540, and a multiplexer (MUX) and / or demultiplexer (DEMUX) (MUX / DEMUX) 550.

[0075] like Figure 5BAs shown in , in some aspects, the millimeter wave repeater 500 may include one or more metamaterial antennas 510 ′- 1 to 510 ′-N, a gain component 520 , a controller 530 , a communication component 540 , and one or more MUX / DEMUX 550 .

[0076] Antenna 510 / 510' includes one or more antenna elements that can be configured for beamforming. Figure 5A As shown in , the millimeter wave repeater 500 may include one or more phased array antennas 510, which may be referred to as a phased array because the phase values ​​and / or phase offsets of the antenna elements may be configured to form beams, where different phase values ​​and / or phase offsets are used for different beams (e.g., in different directions).

[0077] In some aspects, such as Figure 5B As shown in , the millimeter wave repeater 500 may include one or more metamaterial antennas 510'. In some aspects, the metamaterial antenna may include a synthetic material having a negative dielectric constant and / or magnetic permeability, which produces a negative refractive index. Due to the resulting superior antenna gain and electromagnetic lensing, the metamaterial antenna may not need to be used in a phased array configuration. However, if in a phased array configuration, the antenna spacing can be less than the commonly used λ / 2 spacing, where λ refers to the wavelength of the RF carrier signal. In some aspects, due to superior beamforming, the metamaterial antenna can reduce leakage back to the receive (RX) antenna and can reduce the chance of instability in the RF chain. Therefore, the use of metamaterial antennas can reduce or eliminate the need for feedback paths.

[0078] In some aspects, antenna 510 / 510' may be a fixed RX antenna that can only receive communications and not send communications. In some aspects, antenna 510 / 510' may be a fixed TX antenna that can only send communications and not receive communications. In some aspects, antenna 510 / 510' may be configured to act as an RX antenna or a TX antenna (e.g., via a TX / RX switch, MUX / DEMUX, etc.). Antenna 510 / 510' may be capable of communicating using millimeter waves.

[0079] The gain component 520 includes a component capable of amplifying an input signal and outputting an amplified signal. For example, the gain component 520 may include a power amplifier, a variable gain component, etc. In some aspects, the gain component 520 may have a variable gain control. The gain component 520 may be connected to an RX antenna (e.g., a first antenna 510 / 510'-1) and a TX antenna (e.g., a second antenna 510 / 510'-2) so that the analog millimeter wave signal received via the RX antenna can be amplified by the gain component 520 and output to the TX antenna for transmission. In some aspects, the amplification level of the gain component 520 may be controlled by a controller 530.

[0080] The controller 530 includes components capable of controlling one or more other components of the mmWave repeater 500. For example, the controller 530 may include a controller, a microcontroller, a processor, etc. In some aspects, the controller 530 may control the gain component 520 by controlling the gain or amplification level applied to the input signal by the gain component 520. Additionally or alternatively, the controller 530 may control the antenna 510 / 510' by controlling the beamforming configuration of the antenna 510 / 510' (e.g., one or more phase values ​​of the antenna 510 / 510', one or more phase offsets of the antenna 510 / 510', one or more power parameters of the antenna 510 / 510', one or more beamforming parameters of the antenna 510 / 510', TX beamforming configuration, RX beamforming configuration, etc.), by controlling whether the antenna 510 / 510' acts as an RX antenna or a TX antenna (e.g., by configuring the interaction and / or connection between the antenna 510 / 510' and the MUX / DEMUX 550), etc. Additionally or alternatively, controller 530 may turn on or off one or more components of mmWave repeater 500 (eg, when base station 110 does not need to use the mmWave repeater to serve UE 120). In some aspects, controller 530 may control the timing of one or more of the above configurations.

[0081] The communication component 540 may include a component capable of wirelessly communicating with the base station 110 using wireless technologies other than millimeter waves. For example, the communication component 540 may communicate with the base station 110 using a personal area network (PAN) technology (e.g., Bluetooth, Bluetooth low energy (BLE), etc.), 4G or LTE radio access technology, narrowband Internet of Things (NB-IoT) technology, visible light communication technology, etc. In general, the communication component 540 enables communication via a low frequency (LF) interface (e.g., an interface using a frequency lower than 6 GHz) (e.g., with the base station 110). In some aspects, the communication component 540 may use a low frequency communication technology, and the antenna 510 / 510' may use a higher frequency (HF) communication technology (e.g., millimeter waves, etc.). In some aspects, the antenna 510 / 510' may be used to transmit data between the millimeter wave repeater 500 and the base station 110, and the communication component 540 may be used to transmit control information (e.g., reports, configurations, instructions, etc. to turn on or off one or more components) between the millimeter wave repeater 500 and the base station 110.

[0082] MUX / DEMUX 550 may be used to multiplex and / or demultiplex communications received from and / or transmitted to antennas 510 / 510'. For example, MUX / DEMUX 550 may be used to switch an RX antenna to a TX antenna.

[0083] In some aspects, the millimeter wave repeater 500 does not include any components for digital signal processing. For example, the millimeter wave repeater 500 may not include a digital signal processor, a baseband processor, a digital-to-analog converter (DAC), an analog-to-digital converter (ADC), etc. In this way, the cost of producing the millimeter wave repeater 500 can be reduced. In addition, by eliminating digital processing of received millimeter wave signals before transmitting corresponding amplified millimeter wave signals, latency can be reduced.

[0084] In some aspects, one or more antennas 510 / 510', gain components 520, controller 530, communication components 540, MUX / DEMUX 550, etc. may perform one or more operations associated with access process configuration of the mmW repeater, as described in more detail elsewhere herein. For example, one or more components of the mmW repeater 500 may perform or direct e.g. Figure 7 Operations of process 700 and / or other processes as described herein.

[0085] In some aspects, the millimeter wave repeater 500 may include components for receiving configuration information associated with configuring the mmW repeater 500 to participate in an access procedure; components for receiving a signal associated with the access procedure from a first wireless communication device (e.g., a base station 110, a UE 120, etc.); components for forwarding the signal associated with the access procedure to a second wireless communication device (e.g., a UE 120, a base station, etc.) based at least in part on the configuration information and other information associated with the access procedure received by the mmW repeater 500; and so on. In some aspects, such components may include a combination of Figure 5A and Figure 5B One or more components of the millimeter wave repeater 500 are described.

[0086] As mentioned above, providing Figure 5A and Figure 5B As an example. Other examples can be related to Figure 5A and Figure 5B For example, Figure 5A and Figure 5B Compared to the components shown in , the millimeter wave repeater 500 may include additional components, fewer components, different components, or components arranged differently. In addition, Figure 5A and Figure 5B Two or more components shown in may be implemented in a single component, or Figure 5A and Figure 5B A single component shown in may be implemented as multiple components. Additionally or alternatively, a set of components (eg, one or more components) of the millimeter wave repeater 500 may perform one or more functions described as being performed by another set of components of the millimeter wave repeater 500.

[0087] In a wireless communication system, a backhaul link may be established between a base station (e.g., base station 110) and a repeater (e.g., mmW repeater 140). The backhaul link may be used, for example, as a control path for carrying signals (e.g., uplink signals and / or downlink signals) associated with configuring a repeater. A repeater that can configure its operation in this manner may also be referred to as an intelligent repeater or a hybrid node. In some cases, the backhaul link may use a relatively small bandwidth portion in the mmW frequency range (e.g., in FR2), and a relatively low data rate may be achieved. In addition, an access link may be established between a base station and a UE (e.g., UE 120), wherein the repeater is configured to act as a relay between the base station and the UE (e.g., so that the repeater receives and forwards signals on the access link). For example, an access link may be used as a data path for carrying signals (e.g., uplink signals and / or downlink signals) between a base station and a UE. In some cases, the access link may use a relatively large bandwidth in the mmW frequency range, and a relatively high data rate may be achieved. In some deployments, signals on the backhaul link may be multiplexed (eg, frequency domain multiplexing (FDM)) with signals on the access link.

[0088] The operation of the repeater with respect to the access link can be configured via the backhaul link. That is, the operation of the repeater associated with receiving and forwarding signals on the access link can be configured via the backhaul link. For example, the backhaul link can be used to configure the repeater with a beamforming configuration to be used on the access link (e.g., a configuration indicating that one or more beams will be used to receive or forward signals), a switching configuration to be used on the access link (e.g., a configuration indicating whether the repeater will receive and forward signals on the downlink or uplink), and a scheduling to be used on the access link (e.g., an indication of time resources in which the beamforming and switching configurations are employed). Additional examples of configurations that can be provided via the backhaul link include a transmit power configuration for the access link (e.g., a configuration indicating the transmit power to be used when forwarding a signal) and a switch configuration to be used on the access link (e.g., a configuration indicating whether the repeater is to forward a signal or to avoid forwarding a signal).

[0089] In some cases, such configuration of the repeater can be provided using a control signal on the backhaul link. For example, a downlink control information (DCI) format can be defined to enable information associated with one or more of the above configurations to be provided. In some cases, such a control signal can be a common control signal (e.g., DCI) that can be used to (e.g., dynamically and / or semi-statically) configure the operation of the repeater in the upcoming resource set. In general, a common control signal can be used to configure the operation of a repeater associated with any process associated with an access link. For example, a common control signal can be used to configure a repeater for receiving and forwarding cell-specific or broadcast communications (e.g., synchronization signal blocks (SSBs), remaining minimum system information (RMSI), random access channel (RACH) related messages, etc.) on an uplink or downlink. As another example, a common control signal can be used to configure a repeater for receiving and forwarding UE-specific uplink and downlink communications (e.g., semi-statically scheduled communications, dynamically scheduled communications, one-time communications, periodic communications, semi-persistent communications, etc.).

[0090] As a specific example, a common control signal may be used to configure a repeater for operations associated with an initial access procedure associated with an access link. From the perspective of the base station, the initial access procedure includes periodically sending one or more SSBs, and for each SSB, periodically sending a physical downlink control channel (PDCCH) that schedules RMSI, sending a physical downlink shared channel (PDSCH) carrying the scheduled RMSI, and having a RACH opportunity for receiving a RACH message (e.g., a RACH preamble). Here, in order to expand the coverage of the initial access procedure, the base station may need to configure the repeater to receive and forward at least a subset of the SSBs, RMSI PDCCH / PDSCH, and RACH messages associated with the initial access procedure. The base station may use a common control signal to configure the repeater operation on resources associated with these signals related to the initial access procedure. However, the configuration of the repeater using a common control signal may result in an undesirable amount of signaling overhead and / or inefficient resource usage (e.g., due to the number of common control signals required and / or the amount of information to be transmitted in the common control signal).

[0091] Some aspects described herein provide techniques and apparatus for access procedure configuration of a repeater, such as the mmW repeater 140. In some aspects, as described below, information available to the repeater (e.g., information previously received by the repeater) can be utilized to simplify the configuration of the repeater regarding the repeater's participation in the access procedure, which can reduce signaling overhead and / or improve resource usage efficiency when configuring the repeater's participation in the access procedure.

[0092] For example, with respect to an initial access procedure, a repeater using an in-band control path (e.g., a control path in the same frequency band as a data path) has previously detected a base station on the frequency band and acquired system information (SI) associated with the base station. As a result, the repeater will have information indicating the location (e.g., in the time domain) of SSBs transmitted by the base station (e.g., based on a bitmap received in system information block 1 (SIB1) and / or one or more radio resource control (RRC) messages indicating the location of the actual transmitted SSBs), the RMSI PDCCH configuration and resources associated with each SSB, the RACH message (e.g., MSG1) configuration and resources associated with each SSB, and the PDCCH configuration and resources for the RACH response. This information can be utilized to allow the number and / or size of control messages associated with configuring the repeater's participation in the initial access procedure to be reduced, thereby reducing the signaling overhead associated with configuring the repeater and / or improving resource usage efficiency.

[0093] In some aspects, the improved configuration of the repeater can utilize configuration information associated with configuring the repeater's participation in an access process (referred to herein as an access process configuration). In some aspects, the access process configuration may require a relatively small amount of information compared to the configuration provided via a typical common control message. In some aspects, as described in further detail below, the base station can determine the access process configuration and can send the access process configuration to the repeater. The repeater can receive the access process configuration, receive a signal associated with the access process from a first wireless communication device (e.g., a base station, a UE, etc.), and forward the signal associated with the access process to a second wireless communication device (e.g., a UE, a base station, etc.) based at least in part on the access process configuration.

[0094] Figure 6 is a diagram illustrating an example 600 associated with an access procedure configuration of a relay (eg, mmW relay 140) according to the present disclosure. In example 600, the relay will act as a relay between a base station (eg, base station 110) and a UE (eg, UE 120).

[0095] As shown by reference numeral 602 Figure 6 As shown in , the base station can determine configuration information associated with configuring the participation of the relay in forwarding signals during an access procedure (e.g., to / from a UE). Such configuration information is referred to herein as an access procedure configuration. The base station can determine the configuration information using, for example, the transmit processor 220, the receive processor 238, the controller / processor 240, the memory 242, the determining component 1106, etc.

[0096] In some aspects, the access process configuration may include an indication of whether the repeater will forward a signal in resources associated with an SSB set, a PDCCH associated with scheduling an RMSI associated with the SSB set, a RACH message carried in a RACH opportunity associated with the SSB set, a PDCCH associated with scheduling a RACH response, and the like.

[0097] In some aspects, the indication may be carried in a single bit. For example, a single bit may be used to indicate whether the repeater will forward signals (e.g., uplink signals and downlink signals) on resources associated with the SSB set, the PDCCH associated with scheduling the RMSI associated with the SSB set, the RACH message carried in the RACH opportunity associated with the SSB set, and the PDCCH associated with scheduling the response to the RACH message. Here, a first value of a single bit (e.g., 1) may be used to indicate that the repeater will forward signals in resources associated with each of the above-mentioned types of access procedure communications, and a second value of a single bit (e.g., 0) may be used to indicate that the repeater will not forward signals in resources associated with any of these types of access procedure communications.

[0098] Alternatively, in some aspects, the indication may be carried in a bitmap. For example, the bitmap may be used to indicate whether the repeater will forward a signal on resources associated with the SSB set, a PDCCH associated with scheduling an RMSI associated with the SSB set, a RACH message carried in a RACH opportunity associated with the SSB set, and / or a PDCCH associated with scheduling a response to a RACH message. Here, a first value (e.g., 1) in a first bit of the bitmap may be used to indicate that the repeater will forward a signal in resources associated with a first type of access procedure communication (e.g., the SSB set), and a second value (e.g., 0) in the first bit may be used to indicate that the repeater will not forward a signal in resources associated with the first type of access procedure communication. Similarly, a first value in a second bit in the bitmap may be used to indicate that the repeater will forward a signal in resources associated with a second type of access procedure communication (e.g., a PDCCH associated with scheduling an RMSI), and a second value in a second bit may be used to indicate that the repeater will not forward a signal in resources associated with the second type of access procedure communication.

[0099] In some aspects, an access procedure configuration may include a bitmap including a set of bits, wherein a given bit in the bitset indicates whether to forward signals in resources associated with a particular SSB and, optionally, one or more other types of access procedure communications associated with the particular SSB (e.g., a PDCCH associated with scheduling an RMSI associated with the particular SSB, a RACH message associated with the particular SSB, a PDCCH associated with scheduling a RACH response to a RACH message associated with the SSB, etc.). For example, a first value (e.g., 1) in a first bit of the bitmap may be used to indicate that the repeater will forward signals in resources associated with the first SSB and in resources associated with other types of access procedure communications associated with the first SSB, while a second value (e.g., 0) in the first bit of the bitmap may be used to indicate that the repeater will not forward signals in resources associated with the first SSB or in resources associated with other types of access procedure communications associated with the first SSB. Similarly, the first value in the second bit of the bitmap may be used to indicate that the repeater will forward the signal in resources associated with the second SSB and in resources associated with other types of access process communications associated with the second SSB, while the second value in the second bit of the bitmap may be used to indicate that the repeater will not forward the signal in resources associated with the second SSB or in resources associated with other types of access process communications associated with the second SSB. In some aspects, the number of bits in the bitmap may match the maximum number of SSBs for the frequency range in which the repeater is operating (e.g., the bitmap may have a size of 64 bits for FR2). Alternatively, in some aspects, the number of bits in the bitmap may match the number of SSBs actually sent by the base station (which may be pre-indicated to the repeater by the base station via, for example, an RRC message). Alternatively, in some aspects, the bitmap may be a compressed bitmap (e.g., such that the number of bits in the bitmap is less than the number of SSBs actually sent by the base station). In this case, the first bit of the bitmap may correspond to a first subset of SSBs, the second bit of the bitmap may correspond to a second subset of SSBs, and so on (e.g., such that the access process configuration for each subset of SSBs is the same).

[0100] In some aspects, the access procedure configuration may include a beamforming configuration. That is, in some aspects, the access procedure configuration may include beamforming configuration information indicating a beam direction to be used to forward signals in resources associated with the access procedure (e.g., on the serving side).

[0101] As shown in reference numeral 604, the base station may send an access procedure configuration, and the repeater may receive the access procedure configuration. In some aspects, the base station has a control interface to the repeater, and the base station may send the access procedure configuration via the control interface. In some aspects, the base station may send and the repeater may receive the access procedure configuration, via, for example, DCI, medium access control control element (MAC-CE), RRC signaling, etc. The base station may send the access procedure configuration using, for example, a transmit processor 220, an antenna 234, a controller / processor 240, a memory 242, a transmit component 1108, etc. The repeater may receive the access procedure configuration using, for example, an antenna 510, a controller 530, a communication component 540, a receive component 904, etc.

[0102] In some aspects, the base station may send the access procedure configuration in a dedicated control signal associated with configuring the participation of the relay in the access procedure, and the relay may receive the access procedure configuration in a dedicated control signal associated with configuring the participation of the relay in the access procedure. The dedicated control signal may be a signal using, for example, a DCI format configured differently than a common control signal (e.g., a different radio network temporary identifier (RNTI), different resources, etc.). In other words, in some aspects, the access procedure configuration may be communicated in a control signal defined for communicating the access procedure configuration.

[0103] Alternatively, in some aspects, the base station may send the access procedure configuration in a common control signal, and the repeater may receive the access procedure configuration in the common control signal, the common control signal including an indication that the common control signal is associated with configuring the repeater's participation in the access procedure. For example, the access procedure configuration may be provided in a common control signal (e.g., DCI) that includes a header indicating that the purpose of the common control signal is associated with configuring the repeater's participation in the access procedure.

[0104] In some aspects, a repeater receives a signal associated with an access process from a first wireless communication device and forwards the signal to a second wireless communication device. In some aspects, the repeater receives and / or forwards a signal based at least in part on an access process configuration and other information associated with the access process (e.g., information previously received by the repeater). Other information may include, for example, information indicating the location of an SSB set (e.g., in the time domain), an RMSI PDCCH configuration and resources associated with each SSB in the SSB set, a RACH message configuration and resources associated with the SSB in the SSB set, and / or information for a PDCCH configuration and resources for a RACH response associated with a RACH message. In some aspects, such other information may be received from a base station via a SIB, an RRC message, etc. (e.g., when the repeater acquires SI associated with a base station, as described above). The repeater may receive a signal using, for example, an antenna 510, a controller 530, a communication component 540, a receiving component 904, etc. The repeater can forward a signal using, for example, an antenna 510, a controller 530, a communication component 540, a forwarding component 906, a transmitting component 908, and the like.

[0105] As an example, as shown in reference numeral 606, the repeater may receive a first signal associated with an access procedure from a base station, and as shown in reference numeral 608, the first signal may be forwarded to the UE. The first signal may include, for example, a first SSB sent by the base station. Here, the access procedure configuration may indicate (e.g., via a bit indication, via a bitmap, etc.) that the repeater will forward the first SSB, and other information may identify the resources in which the base station will send the first SSB. In this example, the repeater may receive a signal in a resource associated with the first SSB based at least in part on the access procedure configuration and other information, and may forward the signal to the UE.

[0106] As another example, as shown in reference numeral 610, the repeater may receive a second signal associated with an access procedure from the UE, and as shown in reference numeral 612, the second signal may be forwarded to the base station. The second signal may include, for example, a RACH message associated with the first SSB. Here, the access procedure configuration may indicate (e.g., via a bit indication, via a bitmap, etc.) that the repeater will forward the RACH message associated with the first SSB, and other information may identify the resources in which the RACH message associated with the first SSB will be sent by the UE. In this example, the repeater may receive a signal in a resource associated with a RACH message associated with the first SSB based at least in part on the access procedure configuration and other information, and may forward the signal to the base station.

[0107] In some aspects, the repeater may further forward the signal based at least in part on a beamforming configuration received by the repeater (e.g., a beamforming configuration included in the access procedure configuration, a beamforming configuration received by the repeater at an earlier time, etc.).

[0108] As shown above, provide Figure 6 As an example. Other examples can be related to Figure 6 Different than described.
