[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to U.S. Provisional Patent Application No. 62 / 706,178, filed on August 4, 2020, entitled “TECHNIQUES FOR FEEDBACK REPORTING BY A REPEATER,” and U.S. Non-Provisional Patent Application No. 17 / 443,112, filed on July 21, 2021, entitled “TECHNIQUES FOR FEEDBACK REPORTING BY A REPEATER,” which are hereby expressly incorporated herein by reference. Technical Field

[0003] Aspects of the present disclosure generally relate to wireless communications and techniques and apparatus for feedback reporting by repeaters. Background Art

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

[0005] A wireless network may include multiple base stations (BSs) that can support communications for multiple user equipment (UEs). User equipment (UEs) can communicate with a base station (BS) via downlinks and uplinks. A "downlink" (or forward link) refers to the communication link from the BS to the UE, while an "uplink" (or reverse link) refers to the communication link from the UE to the 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] These multiple access technologies have been adopted across various telecommunications standards to provide a common protocol that enables diverse user devices to communicate at the city, national, regional, and even global levels. New Radio (NR), also known as 5G, is a set of enhancements to the LTE mobile standard released by the Third Generation Partnership Project (3GPP). NR is designed to better support mobile broadband internet access by increasing spectral efficiency, reducing costs, improving service, leveraging new spectrum, and integrating better with orthogonal frequency division multiplexing (OFDM) with a cyclic prefix (CP) (CP-OFDM) on the downlink (DL), CP-OFDM and / or SC-FDM (e.g., also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink (UL), as well as other open standards 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 valuable. Summary of the Invention

[0061] 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. On the contrary, these aspects are provided so that the present disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art. Based on the teachings herein, it should be understood by those skilled in the art that the scope of the present disclosure is intended to cover any aspect of the present disclosure disclosed herein, whether the aspect of the present disclosure is implemented independently of any other aspect of the present disclosure or implemented in combination with any other aspect of the present disclosure. For example, any number of aspects set forth herein can be used to implement a device or practice method. In addition, the scope of the present disclosure is intended to cover such a device or method, that is, the device or method uses other structures, functions, or structures and functions in addition to or different from the various aspects of the present disclosure set forth herein to be put into practice. It should be understood that any aspect of the present disclosure disclosed herein can be implemented by one or more elements of the claims.

[0062] Several aspects of telecommunications 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.

[0063] It should be noted that while 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 RATs beyond 5G (e.g., 6G).

[0064] Figure 1 is a diagram illustrating an example of a wireless network 100 according to the present disclosure. The wireless network 100 may be or may include elements of a 5G (NR) network and / or an LTE network, etc. The wireless network 100 may include multiple base stations 110 (shown as BS110a, 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 NRBS, 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 that coverage area, depending on the context in which the term is used.

[0065] A BS may provide communication coverage for macro cells, pico cells, femto cells, and / or other types of cells. A macro cell may cover a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access by UEs with service subscriptions. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs with service subscriptions. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by UEs associated with the femto cell (e.g., UEs in a closed subscriber group (CSG)). A BS for a macro cell may be referred to as a macro BS. A BS for a pico cell may be referred to as a pico BS. A BS for a femto cell may be referred to as a femto BS or a home BS. In Figure 1 In the example shown, BS 110a may be a macro BS for macrocell 102a, BS 110b may be a pico BS for picocell 102b, and BS 110c may be a femto BS for femtocell 102c. A BS may support one or more (e.g., three) cells. The terms "eNB," "base station," "NR BS," "gNB," "TRP," "AP," "Node B," "5G NB," and "cell" may be used interchangeably herein.

[0066] In some aspects, the cells may not necessarily be fixed, and the geographic area of ​​the cells may move depending on 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 via various types of backhaul interfaces (such as direct physical connections, virtual networks, etc.) using any suitable transport network.

[0067] 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, relay BS 110d may communicate with macro BS 110a and UE 120d to facilitate communication between BS 110a and UE 120d. A relay BS may also be referred to as a relay station, relay base station, relay, etc.

[0068] The wireless network 100 may be a heterogeneous network including different types of BSs, such as macro BSs, pico BSs, femto BSs, relay BSs, etc. These different types of BSs may have different transmit power levels, different coverage areas, and different impacts on interference in the wireless network 100. For example, a macro BS may have a higher transmit power level (e.g., 5 watts to 40 watts), while a pico BS, a femto BS, and a relay BS may have a lower transmit power level (e.g., 0.1 watt to 2 watts).

[0069] The network controller 130 may be coupled to a group 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.

[0070] UEs 120 (e.g., 120a, 120b, 120c) may be dispersed throughout the wireless network 100, and each UE may be fixed or mobile. A UE may also be referred to as an access terminal, terminal, mobile station, subscriber unit, station, etc. A UE 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 or instrument, a biometric sensor / device, a wearable device (e.g., a smart watch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring, a smart bracelet)), an entertainment device (e.g., a music or video device, or satellite radio, etc.), a vehicle component or sensor, a smart meter / sensor, industrial manufacturing equipment, a global positioning system device, or any other suitable device configured to communicate via a wireless or wired medium.

[0071] Some UEs may be considered machine type communication (MTC) or evolved or enhanced machine type communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, and / or location tags that can communicate with a base station, another device (e.g., a remote device), or some other entity. A wireless node may provide, for example, a connection to or to a network (e.g., a wide area network such as the Internet or a cellular network) via a wired or wireless communication link. Some UEs may be considered Internet of Things (IoT) devices and / or may be implemented as NB-IoT (Narrowband Internet of Things) devices. Some UEs may be considered customer premises equipment (CPE). UE 120 may be included within 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, the processor component (e.g., one or more processors) and the memory component (e.g., memory) may be operably coupled, communicatively coupled, electronically coupled, and / or electrically coupled, etc.

[0072] In general, 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. RATs can also be referred to as radio technologies, air interfaces, etc. Frequencies can also be referred to as carriers, frequency channels, 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.

[0073] In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) can communicate directly using one or more sidelink channels (e.g., without using base station 110 as an intermediary to communicate with each other). For example, UE 120 can communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which can include vehicle-to-vehicle (V2V) protocols or vehicle-to-infrastructure (V2I) protocols), and / or mesh networks. 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.

[0074] 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 an operating frequency band with a first frequency range (FR1), which can range from 410 MHz to 7.125 GHz, and / or using an operating frequency band with a second frequency range (FR2), which can range from 24.25 GHz to 52.6 GHz. Frequencies between FR1 and FR2 are sometimes referred to as mid-band frequencies. Although a portion of FR1 is greater than 6 GHz, FR1 is often referred to as the "sub-6 GHz" band. Similarly, FR2 is often referred to as the "millimeter wave" band, although it is different from the extremely high frequency (EHF) band (30 GHz–300 GHz), which is designated as a "millimeter wave" band by the International Telecommunication Union (ITU). Therefore, if used herein, unless otherwise explicitly stated, it should be understood that the term "sub-6 GHz" or the like 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, if used herein, unless otherwise expressly stated, it should be understood that the term "millimeter wave" or the like 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 may be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0075] As pointed out above, Figure 1 are provided as examples. Other examples may be related to Figure 1 Different than described.

[0076] Figure 2is a diagram illustrating an example 200 of a base station 110 communicating with a UE 120 in a wireless network 100 according to the present disclosure. The base station 110 may be equipped with T antennas 234a through 234t, and the UE 120 may be equipped with R antennas 252a through 252r, where in general T≥1 and R≥1.

[0077] At the base station 110, a transmit processor 220 may receive data for one or more UEs from a data source 212, select one or more modulation and coding schemes (MCS) for each UE based at least in part on a channel quality indicator (CQI) received from the UE, process (e.g., encode and modulate) data for each UE based at least in part on the MCS selected for the UE, and provide data symbols for all UEs. The transmit processor 220 may also process system information (e.g., for semi-static resource partitioning information (SRPI)) 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)). If applicable, the transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on ​​the data symbols, control symbols, overhead symbols, and / or reference symbols, and may provide T output symbol streams to T modulators (MODs) 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 upconvert) 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.

[0078] At UE 120, antennas 252a through 252r may receive downlink signals from base station 110 and / or other base stations and may provide received signals to demodulators (DEMODs) 254a through 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 through 254r, perform MIMO detection on the received symbols if applicable, and provide detected symbols. A receive processor 258 may process (e.g., demodulate and decode) the detected symbols, provide decoded data for UE 120 to a data sink 260, and provide decoded control information and system information to a controller / processor 280. The 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 channel quality indicator (CQI) parameter, etc. In some aspects, one or more components of the UE 120 may be included in the housing 284.

The transmit processor 264 may also generate reference symbols for one or more reference signals. If applicable, the symbols from the transmit processor 264 may be precoded by a TX MIMO processor 266, 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.

In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 232) of base station 110 may be included in a modem of base station 110. In some aspects, base station 110 includes a transceiver.

[0083] The controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2Any other components of the system may perform one or more techniques associated with feedback reporting by a repeater, as described in more detail elsewhere herein.

[0086] As pointed out above, Figure 2 are provided as examples. Other examples may be related to Figure 2 Different than described.

[0087] Figure 3 300 is a diagram illustrating an example of a repeater node that forwards communications between a first wireless node and a second wireless node according to the present disclosure. As shown, example 300 includes a first wireless node 305 (e.g., an integrated access and backhaul (IAB) node, an IAB donor, a base station 110, a UE 120, etc.), a repeater node 310 (e.g., a repeater device, a base station 110 and a UE 120, a millimeter wave repeater, a digital repeater, an analog repeater, etc.), and a second wireless node 315 (e.g., an IAB node, an IAB donor, a base station 110 and a UE 120, another repeater node 310, etc.). In example 300, the first wireless node 305 and / or the second wireless node 315 may be aware of the repeater node 310. In some aspects, the first wireless node 305 and / or the second wireless node 315 may be unaware of the repeater node 310.

[0088] like Figure 3 As shown, a first wireless node 305 may desire to send a communication 320 (e.g., a data communication, a control communication, etc.) to the second wireless node 315 using a direct link 325 (e.g., an access link, etc.) between the first wireless node 305 and the second wireless node 315. However, the first wireless node 305 may not be able to send the communication 320 to the second wireless node 315 using the direct link 325. For example, the second wireless node 315 may be out of range of the first wireless node 305, the direct link 325 may be blocked, etc. Therefore, the first wireless node 305 may communicate with the second wireless node 315 using an indirect link 330.

[0089] For example, the first wireless node 305 may send a communication 320 (e.g., as a wireless signal) to the repeater node 310. In some aspects, the first wireless node 305 may send the communication 320 directly to the repeater node 310 (e.g., when the first wireless node 305 is aware of the repeater node 310). In some aspects, the repeater node 310 may be configured (e.g., by a control node, by a second wireless node 315, etc.) to receive the communication 320 from the first wireless node 305 (e.g., when the first wireless node 305 is not aware of the repeater node 310).

[0090] like Figure 3 As shown, communication 320 may pass through and be forwarded by repeater node 310. For example, repeater node 310 may receive a wireless signal carrying communication 320 and may regenerate the wireless signal based at least in part on communication 320, the wireless signal, analog processing operations, digital processing operations, etc. Repeater node 310 may transmit the regenerated version of the wireless signal.

[0091] In some cases, the indirect link 330 may be an access link, a side link, or a fronthaul link. For example, if the first wireless node 305 is a base station 110 and the second wireless node 315 is a UE 120, the indirect link 330 between the first wireless node 305 and the repeater node 310 may be a fronthaul link. The indirect link 330 between the repeater node 310 and the second wireless node 315 may be an access link. Figure 3 The communication scheme shown in may improve network performance and reliability by providing link diversity for communication to the first wireless node 305 and / or the second wireless node 315, by expanding the communication coverage area of ​​the first wireless node 305 and / or the second wireless node 315, and the like.

[0092] In a typical scenario, an analog repeater node may be deployed. An analog repeater node may facilitate an indirect link by forwarding communications from a first wireless node to a second wireless node. However, an analog repeater node does not store signals (e.g., communications). Instead, an analog repeater node simply receives a signal and retransmits it without performing any digital processing on the signal. Therefore, an analog repeater node may not provide control over the timing of signal retransmission, may generate self-interference, and may become unstable. To address these issues, some repeater nodes may facilitate digitizing the signal and storing the digitized signal, thereby providing a certain degree of control over timing. In a typical scenario, such a digital repeater may be wired (e.g., via Ethernet), which is limited to retransmitting communications at a specific protocol layer, etc. Therefore, typical analog and digital repeaters may not provide a flexible solution that can be controlled to adapt to various scenarios, channel conditions, etc.

[0093] As pointed out above, Figure 3 are provided as examples. Other examples may be related to Figure 3 Different than described.

[0094] Figure 4 4 is a diagram illustrating an example 400 associated with forwarding wireless signals using a repeater node according to the present disclosure.

In some aspects, the repeater node 405 can include Figure 3 In some aspects, the control node 410, the wireless node 415 and / or the wireless node 420 may be wireless nodes, e.g., Figure 3 The first wireless node 305 shown in Figure 3 The second wireless node 315, IAB node, IAB donor, Figure 1 The base station 110 shown in Figure 1 UE 120 shown in FIG.

[0095] In some aspects, the repeater node 405 may include a millimeter wave repeater configured to receive a millimeter wave signal and transmit a regenerated version of the millimeter wave signal. Figure 4 As shown, the repeater node 405 may include a control component 425 and a retransmission component 430. In some aspects, the control component 425 may facilitate establishing a wireless control interface 435 between the repeater node 405 and the control node 410. In some aspects, the control component 425 may include one or more components and / or functions that are or are similar to a base station (e.g., Figure 1 and Figure 2 ), UE (e.g., Figure 1 and Figure 2 One or more components of the UE 120 shown in FIG.

[0096] In some aspects, the retransmission component 430 can perform one or more retransmission operations. The retransmission operation can be a process that includes receiving a first signal 440, performing one or more digital processing operations on the first signal to generate a second signal 445, and transmitting the second signal 445. The second signal 445 can be the result of the repeater node 405 attempting to regenerate the first signal (e.g., through one or more digital processing operations). In some aspects, the first signal 440 can include a communication sent from the control node 410 and addressed to the wireless node 415 (e.g., Figure 3320 shown in FIG. ). In some aspects, as shown, a first signal 440 may be sent from a control node 410 and addressed to a wireless node 415. In some aspects, the first signal 440 may be sent from a wireless node 415 or a wireless node 420 and addressed to the control node 410, to another wireless node 415 or to the wireless node 420, and so on. In some aspects, the first signal 440 may be addressed to multiple wireless nodes (e.g., the wireless node 415, the wireless node 420, the control node 410, and so on). In some aspects, the first signal 440 may include a physical downlink control channel (PDCCH) transmission, a physical downlink shared channel (PDSCH) transmission, a physical uplink control channel (PUCCH) transmission, a physical uplink shared channel (PUSCH) transmission, a physical sidelink channel transmission, an acknowledgement (ACK) or negative acknowledgement (NACK) (ACK / NACK) feedback message, and so on.

[0097] In some aspects, retransmission component 430 can perform one or more retransmission operations based at least in part on a configuration established using control component 425. For example, in some aspects, control node 410 can transmit configuration 450 using control message 455, and wireless node 420 can receive control message 450 using control component 425.

[0098] The control node 410 may send the configuration 450 in a control message 455 via the control interface 435. The configuration 450 may be carried in at least one control message 455. In some aspects, control messages may be specified for communication between the repeater node 405 and the control node 410 according to a specification of the control interface 435. In some aspects, the configuration 450 may be carried in a lower layer control message (e.g., a control message associated with the physical layer and / or the medium access control (MAC) layer), an upper layer control message (e.g., a control message associated with the network layer), an application layer control message (e.g., a control message associated with the application layer), etc. For example, the control message may be carried using a radio resource control (RRC) message, a downlink control information (DCI), a MAC control element (MAC-CE), etc.

[0099] In some aspects, the control message may be included within the first signal 440. In some aspects, the configuration 450 may be carried in a fronthaul physical downlink control channel (FH-PDCCH) control message. In some aspects, the FH-PDCCH control message may include DCI scrambled by a fronthaul radio network temporary identifier (FH-RNTI). The FH-RNTI may be associated with the control component.

[0100] In some aspects, the retransmission component 430 may communicate using millimeter waves, while the control component 425 may communicate using frequencies below millimeter wave frequencies. For example, in some aspects, the control component 425 may communicate using sub-6 (sub-6GHz) frequencies. In some aspects, the control node 410 may send and the repeater node 405 may receive a configuration of the control interface 435 or one or more aspects thereof. In some aspects, for example, the control node 410 may send a configuration of a frequency, bandwidth, bandwidth part (BWP), etc. In some aspects, the retransmission component 430 may communicate using a first RAT (e.g., NR) and the control component 425 may communicate using a second RAT (e.g., LTE, Bluetooth, WiFi, etc.). In some aspects, the control interface 435 may include an access link between the control component 425 and the control node 410.

[0101] In some aspects, the control message 455 can configure any number of different types of settings, configurations, digital processing operations, receiving operations, buffering operations, forwarding (sending) operations, etc. In some aspects, the repeater node 405 can send and the control node 410 can receive one or more control messages. For example, in some aspects, the repeater node 405 can use the control component 425 to send control messages to the control node via the control interface 435. The control messages sent by the digital repeater can indicate the configuration of the digital repeater, the capabilities of the digital repeater, the status of the digital repeater, etc.

[0102] As noted above, in some aspects, the control node 410 can configure the repeater node 405 for a particular retransmission operation by sending a configuration 450 to the repeater node 405. In some aspects, the configuration 450 can indicate a digital processing operation. The digital processing operation can include selecting from a plurality of digital processing options (e.g., Figure 5 In some aspects, configuration 450 may include one or more information elements (IEs) indicating receive configuration, buffer configuration, forwarding configuration, information request, etc.

[0103] In some aspects, the receive configuration may be used to configure various aspects of the receive operation of the retransmit component 430 with respect to receiving the first signal 440. For example, the receive configuration may indicate a receive analog beamforming configuration, time domain resources associated with the first signal, frequency domain resources associated with the first signal, a parameter set associated with the first signal, a digital receiver beamforming configuration, resource element (RE) mapping information associated with the first signal, a channel estimation configuration, a scrambling identifier associated with the first signal, a coding configuration associated with the first signal, and the like.

[0104] In some aspects, the buffer configuration can be used to configure various aspects of the buffering operation of the retransmission component 430 with respect to buffering the digitized form of the first signal 440. In some aspects, the buffer configuration can indicate analog-to-digital converter (ADC) settings, digital-to-analog converter (DAC) settings, in-phase and quadrature (IQ) sample compression settings, IQ sample decompression settings, etc.

[0105] In some aspects, the forwarding configuration can be used to configure various aspects of the forwarding operation of the retransmission component 430 with respect to transmitting the second signal 445, which can be a regenerated version of the first signal 440. In some aspects, the forwarding configuration can include a transmit beamforming configuration, time domain resources associated with transmitting the second signal, a transmit power setting, a transmit amplification setting, a transmit center frequency, a parameter set associated with transmitting the second signal, a digital transmitter beamforming configuration, RE mapping information associated with transmitting the second signal, a layer mapping configuration, a precoding configuration, a scrambling identifier associated with transmitting the second signal, a coding configuration associated with transmitting the second signal, and the like.

[0107] As pointed out above, Figure 4 are provided as examples. Other examples may be related to Figure 4 Different than described.

[0108] Figure 5 5 is a diagram illustrating an example 500 of forwarding wireless signals using a repeater node according to the present disclosure. As shown, the example 500 includes a repeater node 505 that can communicate with a control node 510 and a wireless node 515. In some aspects, the repeater node 505 can communicate with one or more additional wireless nodes (not shown).

[0109] In some aspects, the repeater node 505 may include Figure 4 The repeater node 405 shown in Figure 3 In some aspects, the control node 510 may include Figure 4 The control node 410 shown in Figure 3 The first wireless node 305 shown in Figure 3 The second wireless node 315, IAB node, IAB donor, Figure 1 The base station 110 shown in Figure 1 In some aspects, the wireless node 515 may include a UE 120, etc. Figure 4 The wireless node 415 shown in Figure 4 The wireless node 420 shown in Figure 3 The first wireless node 305 shown in Figure 3 The second wireless node 315, IAB node, IAB donor, Figure 1 The base station 110 shown in Figure 1 UE 120 shown in FIG.

[0110] As shown at reference numeral 520, the control node 510 may send and the repeater node 505 may receive a configuration. In some aspects, the configuration may be, be similar to, or include Figure 4 In some aspects, the configuration 450 shown in or included therein can be controlled via a control interface (e.g., Figure 4 ) uses the control components of the repeater node 505 (e.g., Figure 4 The configuration may be received by a control component 425 shown in FIG. In some aspects, the configuration may be received using a wireless fronthaul link. The configuration may indicate a digital processing operation. The digital processing operation may be a retransmission operation that includes at least obtaining a plurality of digital samples from the first signal and storing the plurality of digital samples.

[0111] The retransmission operation may include a repeater receiving a first signal from a first wireless node, processing the signal to generate a second signal, and transmitting the second signal to a second wireless node. In some aspects, processing the first signal may include regenerating the first signal based at least in part on digital processing of the first signal (by generating a regenerated version of the first signal, which is interchangeably referred to herein as a "regenerated signal"). In this manner, the repeater node 505 may retransmit a signal received from the first wireless node to the second wireless node. Transmitting the regenerated signal may be referred to as forwarding the regenerated signal, performing a forwarding operation, performing a retransmission operation, etc.

[0112] like Figure 5 As shown, the processing operation indicated by the configuration may include processing options selected from a plurality of processing options. The plurality of processing options may include a first processing option 525 (shown as a processing block and associated intermediate output "Analog Signal" located to the right of the first vertical dashed line from the right), which may be based at least in part on analog processing of the received signal. The plurality of processing options may include a second processing option 530 (shown as a processing block and associated intermediate output "Analog Signal" and "TD IQ Samples" located to the right of the second vertical dashed line from the right), which may be based at least in part on determining and buffering time domain (TD) IQ samples.

[0113] The plurality of processing options may include a third processing option 535 (shown as a processing block and associated intermediate outputs "Analog Signal," "TD IQ Samples," and "FD IQ Samples," located to the right of the third vertical dashed line from the right), which may be based at least in part on tone extraction. Tone extraction may include determining frequency domain (FD) IQ samples. The plurality of processing options may include a fourth processing option 540 (shown as a processing block and associated intermediate outputs "Analog Signal," "TD IQ Samples," "FD IQ Samples," and "Symbol / Antenna," located to the right of the fourth vertical dashed line from the right), which may be based at least in part on resource element (RE) extraction. Extraction of REs may include determining symbols and antenna elements, antenna configuration, etc.

[0114] The plurality of processing options may include a fifth processing option 545 (shown as processing blocks and associated intermediate outputs "Analog Signal," "TD IQ Samples," "FD IQ Samples," "Symbol / Antenna," and "Codeword," located to the right of the fifth vertical dashed line from the right), which may be based at least in part on channel estimation and equalization.

[0115] According to various aspects, the second, third, fourth, fifth and sixth processing options 530-550 can be referred to as digital processing options, because they comprise the processing of digital information. The repeater node that can perform and / or be configured to only perform the first processing option can be referred to as analog repeater. The repeater node that can perform and / or be configured to perform any one or more options in the second, third, fourth, fifth or sixth processing options 530-550 can be referred to as digital repeater (for example, repeater node 505). Therefore, this configuration can indicate the digital processing option selected from the second, third, fourth, fifth and sixth processing options 530-550. In some aspects, configuration can include that repeater node 505 can use to be conducive to the information of performing processing option, as discussed below in conjunction with various processing options.

[0116] As shown at reference numeral 555, the control node 510 may send and the repeater node 505 may receive a first signal. In some aspects, the first signal may be, be similar to, or include Figure 4 The first signal 440 shown in or included therein may be received by the control node 510, the wireless node 515 or Figure 5 As shown in reference numeral 560, the repeater node 505 can perform digital processing operations on the first signal to generate a second signal. As described above, the second signal can be a regenerated version of the first signal.

[0117] In some aspects, the repeater node 505 may perform digital processing operations as indicated by the configuration. In addition to performing digital processing operations, or as an alternative to performing digital processing operations, the digital repeater may also be configured to perform analog processing operations, as indicated by the first processing option 525. In the first processing option 525, the repeater node 505 may receive a first signal and may perform an analog beamforming process to obtain a second analog signal associated with the first signal. The repeater node 505 may extract the analog signal and may regenerate the analog signal in a transmit (Tx) chain of the repeater node 505. For example, the repeater node 505 may perform an analog beamforming process on the analog signal to form an output signal (e.g., the repeater node 505 may enhance the analog signal, apply analog beamforming gain, etc.).

[0118] In accordance with some aspects, to support the first processing option 525, the repeater node 505 may receive one or more control messages from the control node 510 (e.g., in the configuration shown by reference numeral 520) indicating a receive beamforming configuration associated with the first signal, a transmit beamforming configuration associated with transmitting the second signal, and the like. In some aspects, the receive beamforming configuration may indicate an index associated with a beamforming codebook. In some aspects, the repeater node 505 may send a control message to the control node 510 indicating beamforming codebook characteristics. The beamforming codebook characteristics may indicate, for example, the number of available transmitter beams, the number of available receiver beams, spatial quasi-co-location characteristics associated with the beams, the number of antenna arrays, the number of antenna panels, associations between beams and antenna arrays, associations between beams and antenna panels, and the like.

[0119] In some aspects, the receive beamforming configuration may indicate phase settings of antenna elements of the repeater node 505, amplitude settings of antenna elements of the repeater node 505, etc. In some aspects, the repeater node 505 may send a control message to the control node 510 indicating the beamforming capabilities of the repeater node 505, and the receive beamforming configuration may be based at least in part on the beamforming capabilities.

[0120] In some aspects, the repeater node 505 may send a control message indicating a transmitter power configuration to the control node 510, and the configuration received from the control node 510 may indicate one or more transmitter power and / or amplification settings based at least in part on the transmitter power configuration. In some aspects, the transmitter power configuration may indicate a power headroom, a maximum transmitter power, a maximum gain level, a current gain setting, a current transmitter power, etc.

[0121] In the second processing option 530, in some aspects, the repeater node 505 can perform digital signal processing (which also includes the first processing option). As shown, after receiving the incoming signal and performing the analog beamforming process associated with the incoming signal, the repeater node 505 can convert the incoming signal from the analog domain to the digital domain using an analog-to-digital converter (ADC). After converting the incoming signal from the analog domain to the digital domain, the repeater node 505 can determine one or more time domain IQ samples associated with the incoming signal (shown as "TD IQ samples"). The repeater node 505 can extract the time domain IQ samples and can store the time domain IQ samples in a buffer of the repeater node. The repeater node 505 can use the time domain IQ samples to regenerate the incoming signal in the Tx chain of the repeater node 505 (e.g., immediately after extracting the time domain IQ samples or at a later time). For example, the repeater node 505 can use a digital-to-analog converter (DAC) to convert the time domain IQ samples from the digital domain to the analog domain. Before sending the second signal to the wireless node 515 , the repeater node 505 may perform an analog beamforming process on the analog signal according to the first processing option 525 to form the second signal.

[0122] In some aspects, to facilitate the repeater node 505 to perform the second processing option, the configuration can indicate a reception configuration, a buffering configuration, a forwarding configuration, an information request, etc. In some aspects, for example, the configuration can indicate a timing configuration. The timing configuration can include various aspects of the reception configuration, the buffering configuration, the forwarding configuration, etc.

[0123] In some aspects, for example, the receive configuration may indicate a receive analog beamforming configuration, time domain resources associated with the first signal, frequency domain resources associated with the first signal, etc. In some aspects, the frequency domain resources associated with the first signal may include a center frequency, a bandwidth, a BWP, etc.

[0124] In some aspects, the buffer configuration may indicate ADC settings (e.g., ADC resolution, sampling rate, etc.), DAC settings, IQ sample compression settings, IQ sample decompression settings, buffer status (e.g., available memory, maximum buffer size, buffer overflow, etc.), ADC configuration, DAC configuration, IQ capabilities, IQ settings, etc.

[0125] In some aspects, the forwarding configuration may indicate a transmit beamforming configuration, a time domain resource associated with transmitting the second signal, a transmit power setting, a transmit amplification setting, a transmit center frequency, and the like. In some aspects, the transmit time domain resource may be indicated relative to the receive time domain resource. The transmit time domain resource may be based at least in part on a synchronization characteristic corresponding to a synchronization pattern between the digital repeater and the control node. For example, the synchronization characteristic may indicate a synchronization pattern between the digital repeater and the control node, and the transmit time domain resource may be based at least in part on an indication of the receive time domain resource (e.g., a symbol identifier, a time slot identifier, a frame identifier, etc.).

[0126] In a third processing option 535, in some aspects, the repeater node 505 may perform further digital processing (which may also include the second processing option and the first processing option). As shown, for example, after converting the incoming signal from the analog domain to the digital domain, the repeater node 505 may remove a cyclic prefix (CP) associated with the incoming signal and may perform a fast Fourier transform (FFT) on the incoming signal. Based at least in part on removing the CP and performing the FFT, the repeater node 505 may determine one or more frequency domain IQ samples (shown as "FD IQ samples") associated with the incoming signal. The frequency domain IQ samples may correspond to tones (e.g., OFDM tones). The repeater node 505 may extract the frequency domain IQ samples and may store the frequency domain IQ samples in a buffer of the repeater node 505. The repeater node 505 may use the frequency domain IQ samples to regenerate the incoming signal in the Tx chain of the repeater node 505 (e.g., immediately after extracting the frequency domain IQ samples or at a later time). For example, the repeater node 505 may perform an inverse FFT (iFFT) operation on the frequency domain IQ samples to generate regenerated time domain IQ samples. The repeater node 505 may add a CP to the regenerated time domain IQ samples. The repeater node 505 may use a DAC to convert the digital signal (e.g., the regenerated digital samples) from the digital domain to the analog domain. The repeater node 505 may perform an analog beamforming process on the analog signal to form a second signal.

[0127] In some aspects, the configuration may indicate other IEs associated with the receive configuration and / or transmit configuration to facilitate repeater node 505 in performing third processing option 535. These other IEs may be in addition to the IEs described above in conjunction with second processing option 530, first processing option 525, etc.

[0128] In some aspects, for example, the receive configuration may indicate a parameter set associated with the first signal, and the forward configuration may indicate a parameter set associated with transmitting the second signal. In some aspects, the parameter set associated with the first signal may be the same as the parameter set associated with transmitting the second signal. In some aspects, the parameter set associated with the first signal may be different from the parameter set associated with transmitting the second signal. In some aspects, the parameter set associated with the first signal and / or the parameter set associated with transmitting the second signal may include at least one of a cyclic prefix size, a subcarrier spacing, a fast Fourier transform size, and the like.

[0129] In the fourth processing option 540, in some aspects, the repeater node 505 may perform further digital processing (which may also include the third processing option, the second processing option, and the first processing option). In some aspects, in the fourth processing option 540, after removing the CP and performing the FFT associated with the incoming signal, the repeater node 505 may perform a digital beamforming process associated with the incoming signal. The repeater node 505 may perform an RE demapping operation associated with the incoming signal to extract REs based at least in part on the determined tones. After performing the digital beamforming process and the RE demapping process, the repeater node 505 may determine one or more IQ samples (e.g., the number of symbols per antenna element) of the occupied tones associated with the incoming signal. The repeater node 505 may extract the IQ samples of the occupied tones and may store the IP samples of the occupied tones in a buffer of the repeater node 505. The repeater node 505 can use the IQ samples of the occupied tones to regenerate the incoming signal in the Tx chain of the repeater node 505 (e.g., immediately after extracting the IQ samples of the occupied tones or at a later time). For example, the repeater node 505 can perform an RE mapping process associated with the IQ samples of the occupied tones (e.g., the inverse of the RE demapping process). The repeater node 505 can perform a digital beamforming process associated with the IQ samples of the occupied tones. After performing the digital beamforming process, the repeater node 505 can perform an iFFT process and add a CP to the signal. As noted above, the repeater node 505 can use a DAC to convert the digital signal from the digital domain to the analog domain.

[0130] In some aspects, the configuration may indicate other IEs associated with the receive configuration and / or transmit configuration in order to facilitate the repeater node 505 in performing the fourth processing option 540. These other IEs may be in addition to the IEs described above in conjunction with the third processing option 535, the second processing option 530, the first processing option 525, etc.

[0131] In some aspects, for example, the receive configuration may indicate a digital receiver beamforming configuration, and the forwarding configuration may indicate a digital transmitter beamforming configuration. In some aspects, the receive configuration may indicate RE mapping information associated with a first signal, and the forwarding configuration may indicate RE mapping information associated with transmitting a second signal. In some aspects, the RE mapping information associated with the first signal may include a plurality of indices corresponding to a plurality of occupied tones associated with the first signal. In some aspects, the RE mapping information associated with forwarding the first signal may include a plurality of indices corresponding to a plurality of occupied tones associated with transmitting the second signal.

[0132] In the fifth processing option 545, in some aspects, the repeater node 505 may perform further digital processing (which may also include the fourth processing option, the third processing option, the second processing option, and the first processing option). In some aspects, in the fifth processing option 545, after performing the digital beamforming process and the RE demapping operation, the repeater node may perform channel estimation and equalization associated with the incoming signal (e.g., determining and / or removing noise and radio channel variations associated with the incoming signal). For example, the first signal may include a source signal attenuated by the radio channel characteristics of the radio channel carrying the first signal. The channel estimation may be performed at least in part based on one or more reference signals transmitted by the control node 510, the wireless node 515, etc. In some aspects, performing the fifth digital processing option 545 may include stabilizing the radio channel characteristics associated with the extracted set of REs (extracted during the execution of the fourth processing option 540) based at least in part on the channel estimation to generate a stabilized set of REs. The repeater node 505 may generate the second signal based at least in part on the stabilized REs.

[0133] After performing channel estimation and equalization, the repeater node 505 may perform a demodulation operation to determine a set of codewords associated with the incoming signal. The repeater node 505 may extract the codeword and may store the codeword in a buffer of the repeater node 505. The repeater node 505 may use the codeword to regenerate the incoming signal in the Tx chain of the repeater node 505 (e.g., immediately after extracting the codeword or at a later time). For example, the repeater node 505 may perform a modulation operation, a layer mapping operation, a precoding operation, an RE mapping operation, and / or a digital beamforming process associated with the codeword.

[0134] In some aspects, the configuration may indicate other IEs associated with the receive configuration and / or transmit configuration in order to facilitate the repeater node 505 in performing the fifth processing option 545. These other IEs may be in addition to the IEs described above in conjunction with the fourth processing option 540, the third processing option 535, the second processing option 530, the first processing option 525, etc.

[0135] For example, in some aspects, a receive configuration may indicate a channel estimation configuration. In some aspects, a channel estimation configuration may indicate resources associated with a reference signal, a configuration associated with a reference signal, etc. In some aspects, a forwarding configuration may indicate a layer mapping configuration, a precoding configuration, etc.

[0136] In the sixth processing option 550, in some aspects, the repeater node 505 can perform the sixth digital processing option (which can also include the fifth processing option, the fourth processing option, the third processing option, the second processing option, and the first processing option). In some aspects, for example, in the sixth processing option 550, the repeater node 505 can extract a transport block (or multiple transport blocks) based at least in part on a stable set of REs. In some aspects, the repeater node 505 can perform a descrambling operation (e.g., using a scrambling identifier associated with the incoming signal) to generate a descrambled set of REs. The repeater node 505 can decode the descrambled set of REs based on a network coding scheme associated with the incoming signal to determine one or more transport blocks. The repeater node 505 can extract the transport block and can store the transport block in a buffer of the repeater node 505.

[0137] The repeater node 505 may use the transport block to regenerate an incoming signal in the Tx chain of the repeater node 505 (e.g., immediately after extracting the transport block or at a later time). For example, the repeater node 505 may encode the transport block (e.g., according to a network coding scheme) to generate a set of recoded REs. The repeater node 505 may scramble the recoded REs to create a regenerated version of the first signal. The repeater node 505 may perform modulation operations, layer mapping operations, precoding operations, RE mapping operations, and / or digital beamforming processes associated with the scrambled transport block.

[0138] In some aspects, the configuration may indicate other IEs associated with the receive configuration and / or transmit configuration in order to facilitate the repeater node 505 in performing the sixth processing option 550. These other IEs may be in addition to the IEs described above in conjunction with the fifth processing option 545, the fourth processing option 540, the third processing option 535, the second processing option 530, the first processing option 525, etc.

[0139] In some aspects, for example, the reception configuration may indicate a scrambling identifier associated with the first signal, a coding configuration associated with the first signal, and the like. In some aspects, the scrambling identifier may include an FH-RNTI. The FH-RNTI may correspond to the repeater node 505. In some aspects, the coding configuration may indicate a modulation and coding scheme (MCS), a coding technique, and the like. In some aspects, the forwarding configuration may indicate a scrambling identifier (e.g., a radio network temporary identifier (RNTI)) associated with transmitting the second signal, a coding configuration associated with transmitting the second signal, and the like.

[0140] As described above, the repeater node 505 may generate a second signal based at least in part on digital processing operations. As shown at 565, the repeater node 505 may send and the wireless node 515 may receive the second signal. In some aspects, the repeater node 505 may send a signal to the control node 510, another wireless node ( Figure 5 ) etc. to send a second signal.

[0141] As described above, different processing operations for a retransmission operation are described. A retransmission operation can differ from a relay operation in that a retransmission operation attempts to regenerate a received signal. In contrast, a relay operation can determine information (e.g., payload) included in a first communication by fully decoding the communication. A relay operation can include generating a second communication to be relayed that is based at least in part on the payload of the first communication (e.g., the second communication is different from the first communication, and the retransmission operation attempts to regenerate or recreate the first communication).

[0142] As pointed out above, Figure 5 are provided as examples. Other examples may be related to Figure 5 Different than described.

[0143] In some cases, a repeater node may provide feedback related to communications received from a control node (e.g., a wireless node that controls, configures, and / or schedules the repeater node) or another wireless node. For example, a repeater node may provide feedback related to communications from a control node indicating the configuration of the repeater node. In some cases, a repeater node may receive communications, decode the communications to determine information included in the communications (e.g., payload), and provide feedback to a sending node (e.g., a wireless node that sent the communications) indicating the quality of the decoded communications. However, as discussed above with respect to Figure 3 、 Figure 4 and Figure 5 As described above, when performing digital retransmission operations, the repeater node may not be able to fully decode the communication to be forwarded by the repeater node. For example, the repeater node may perform a certain level of processing on the signals associated with the communication (e.g., the above description of Figure 5The repeater node may use one of the processing options described above to extract some information related to the signal, regenerate the signal, and transmit the regenerated signal. As a result, the control node and / or the transmitting node (e.g., a wireless node transmitting a communication to be forwarded by the repeater node) may not be aware of the quality of the communication received by the repeater node. This may result in poor network performance because the repeater node may regenerate signals for communications associated with poor channel conditions (e.g., poor quality, poor power, etc.).

[0144] Some of the techniques and devices described herein enable a repeater to provide feedback reporting on signals of communications to be forwarded by a repeater node. For example, a repeater node may receive communications to be forwarded by the repeater node as part of a digital retransmission operation. The repeater node may perform measurements associated with the communications. The repeater node may send feedback communications to a control node that are based, at least in part, on the measurements associated with the communications. Thus, the control node may be enabled to determine channel conditions associated with the communications received by the repeater node. The feedback communications enable the control node to make improved configuration and / or scheduling decisions for the repeater node. Thus, network performance is improved because the control node may ensure that the repeater node is scheduled and / or configured to forward communications based, at least in part, on feedback associated with the communications.

[0145] Figure 6 6 is a diagram illustrating an example 600 associated with a feedback report of a repeater according to the present disclosure. Figure 6 As shown, a control node 605, a repeater node 610, and one or more wireless nodes 615 may communicate with each other in a wireless network (eg, wireless network 100).

[0146] In some aspects, the control node 605 may be Figure 3 The first wireless node 305 or the second wireless node 305 depicted in Figure 4 The control node 410 depicted in Figure 5 The control node 510, base station 110, central unit (CU) of IAB donor, distributed unit (DU) of IAB node, IAB node, etc. are depicted in FIG. In some aspects, the repeater node 610 can be Figure 3 The repeater node 310 depicted in Figure 4 The repeater node 405 depicted in Figure 5 Repeater node 505, repeater device, remote unit of IAB node, repeater station, layer 1 repeater device, millimeter wave repeater device, digital repeater device, base station 110, UE 120, IAB node, etc. depicted in FIG. In some aspects, one or more wireless nodes 615 may include Figure 3 The first wireless node 305 or the second wireless node 305 depicted in Figure 4 The wireless node 415 depicted in Figure 5 5. In some aspects, the repeater node 610 may communicate with multiple wireless nodes 615. In some aspects, the repeater node 610 may communicate with multiple control nodes 605.

[0147] As shown in reference numeral 620, the control node 605 may send and the repeater node 610 may receive a configuration for a retransmission operation. As described above, the configuration may indicate a digital processing operation. The digital processing operation may include a digital processing option selected from a plurality of digital processing options, as described above in conjunction with Figure 5 Explained.

[0148] The configuration for the retransmission operation may include a feedback configuration. The feedback configuration may indicate the resources used by the repeater node 610 to send feedback communications, the configuration of transmission parameters associated with sending feedback communications used by the repeater node 610 when sending feedback communications (e.g., transmit power, beamforming configuration, etc.). In some aspects, the feedback configuration may indicate the type of feedback to be provided by the repeater node 610 (e.g., acknowledgement or negative acknowledgement (ACK / NACK) feedback, measurement report, etc.). In some aspects, the feedback configuration may indicate a measurement configuration associated with performing measurements of communications to be forwarded by the repeater node 610. The measurement configuration may indicate the beams, signals, reference signals, etc. that the repeater node is to measure to determine channel condition values ​​associated with the received communications.

[0149] In some aspects, the feedback configuration may be provided together with the configuration for the retransmission operation. In some aspects, the feedback configuration may be provided separately from the configuration for the retransmission operation. The control node 605 may send the feedback configuration semi-statically and / or dynamically. The feedback configuration may be carried using an RRC message, a DCI, a MAC-CE, or the like.

[0150] As shown by reference numeral 625, the control node 605 can send and the repeater node 610 can receive the communication signal. Alternatively, the wireless node 615 can send the communication signal to the repeater node 610. The communication can be associated with a digital retransmission operation. That is, the repeater node 610 can be configured and / or scheduled to forward the communication (e.g., to the control node 605, the wireless node 615, etc.).

[0151] In some aspects, the communication may be a PDCCH communication, a PDSCH communication, a PUCCH communication, a PUSCH communication, a physical sidelink channel communication, or the like.

[0152] As shown in reference numeral 630, the repeater node 610 can perform measurements associated with the communication. The repeater node 610 can perform measurements associated with the signal of the communication based on the feedback configuration received from the control node 605. For example, the repeater node 610 can determine a channel condition value associated with the signal of the communication. The channel condition value may include a measured received power value, a measured received quality value, a signal-to-noise ratio (SNR) value, etc. In some aspects, the repeater node 610 can measure the signal of the communication to determine the channel condition value. In some aspects, the repeater node 610 can measure a reference signal associated with the communication (e.g., a synchronization signal block (SSB), a channel state information (CSI) reference signal (CSI-RS), a DMRS, a phase tracking reference signal (PTRS), a sounding reference signal (SRS), etc.). For example, the channel condition value may include a channel quality indicator (CQI) value, a CSI-RS resource indicator (CRI) value, an RSRP value, an RSSI value, an RSRQ value, an SNR value, a signal to interference plus noise ratio (SINR) value, etc.

[0153] In some aspects, the repeater node 610 may determine whether to provide feedback for a communication based at least in part on measurements associated with the communication. In some aspects, for example, if a channel condition value for a communication meets a threshold, the repeater node 610 may not provide feedback to the control node 605.

[0154] As shown by reference numeral 635, the repeater node 610 may send, and the control node 605 may receive, feedback communications associated with communications to be forwarded by the repeater node 610. The feedback communications may be based, at least in part, on measurements associated with the communications. For example, the feedback communications may be ACK / NACK feedback indicating the quality of the communications. That is, if the channel condition value of the communications meets a threshold, the feedback communications may be ACK feedback, or if the channel condition value of the communications does not meet the threshold, the feedback communications may be NACK feedback.

[0155] In some aspects, the feedback communication may include a measurement report. The measurement report may indicate one or more channel condition values ​​associated with the communication. In some aspects, the repeater node 610 may send the measurement report to the control node 605 based at least in part on the channel condition value. For example, if the channel condition value does not meet a threshold, the repeater node 610 may send the measurement report to the control node 605. If the channel condition value does meet the threshold, the repeater node 610 may not send the measurement report to the control node 605. In this way, when the channel condition value meets the threshold (e.g., when the communicated signal has good quality or power), the repeater node 610 can save resources that would otherwise be used to send the measurement report to the control node 605.

[0156] In some aspects, the repeater node 610 may send a feedback communication (e.g., as Figure 6 In some aspects, the repeater node 610 may send the feedback communication after forwarding the communication according to the retransmission operation (e.g., after the operation explained below with respect to reference numeral 655).

[0157] In some aspects, the repeater node 610 may send feedback communications to the control node 605 and one or more other wireless nodes 615. For example, if the control node 605 did not send a communication, the repeater node 610 may send feedback communications to the control node 605 and the wireless node 615 that sent the communication.

[0158] The control node 605 can receive feedback communications from the repeater node 610, and can use the feedback communications to make improved configuration and / or scheduling decisions for the repeater node 610. As shown in reference numeral 640, the control node 605 can determine the updated configuration for the retransmission operation based at least in part on the feedback communications. For example, the control node 605 can determine that the repeater node 610 should not forward the communication (e.g., at least in part based on receiving NACK feedback from the repeater node 610, at least in part based on receiving an indication of a channel condition value that does not meet a threshold value from the repeater node 610, etc.). The control node 605 can send an indication of not forwarding the received communication to the repeater node 610. Alternatively, the control node 605 can cause the communication to be retransmitted to the repeater node 610 (e.g., the control node 605 can retransmit the communication to the repeater node 610, the control node 605 can instruct the wireless node 615 that originally sent the communication to retransmit the communication to the repeater node 610, etc.). In some aspects, the control node 605 may cause the communication to be retransmitted using a different transmit configuration (e.g., using a different transmit power, a different transmit beam, a different rate, etc.) to adapt to the channel conditions indicated by the feedback communication.

[0159] In some aspects, the control node 605 may determine, based at least in part on the feedback communication, an updated configuration for a retransmission operation to be performed by the repeater node 610. For example, the control node 605 may determine an updated transmit configuration for the repeater node 610 to use when forwarding the communication, an updated transmit power for the repeater node 610 to use when forwarding the communication, an updated beamforming setting for the repeater node 610 to use when forwarding the communication, etc. In some aspects, the control node 605 may determine that the retransmission operation should include forwarding one or more retransmissions of the communication (e.g., the repeater node 610 should transmit a regenerated signal of the communication in the one or more retransmissions).

[0160] In some aspects, the control node 605 may determine an updated configuration for retransmission operations for upcoming communications based at least in part on the feedback communications.For example, the control node 605 may determine updated configuration or scheduling information that the repeater node 610 will use for retransmission operations for future communications.

[0161] In some aspects, the control node 605 can utilize feedback communications when the communication to be forwarded by the repeater node 610 is a semi-static communication that is not accompanied by a dynamic PDCCH communication from the control node 605 to the repeater node 610. For example, the control node 605 can send an initial PDCCH communication to the repeater node 610 indicating that the repeater node 610 will forward the communication to a destination node (e.g., a wireless node 615, the control node 605, etc.) according to the semi-static schedule. Future communications to be forwarded by the repeater node 610 to the destination node following the semi-static schedule may not be triggered or accompanied by a PDCCH communication from the control node 605 to the repeater node 610. Thus, the feedback communications can enable the control node 605 to evaluate channel conditions associated with future communications to make improved configuration and / or scheduling decisions for the repeater node 610.

[0162] In some aspects, the control node 605 can utilize feedback communications when the communications to be forwarded by the repeater node 610 are periodic communications to be stored by the repeater node 610. For example, the control node 605 can instruct the repeater node 610 to receive the communications, digitally process the communications (e.g., in accordance with the above description of Figure 5 In some aspects, the communication received by the repeater node 610 may be associated with poor channel conditions. Thus, the feedback communication may enable the control node 605 to replace (e.g., overwrite) the stored signal with a new signal associated with the communication (e.g., the control node 605 may retransmit the new signal to replace the stored signal, the control node 605 may instruct the wireless node 615 to retransmit the new signal to replace the stored signal, etc.). Therefore, the feedback communication may improve the performance of such periodic communications to be forwarded by the repeater node 610 by ensuring that the repeater node 610 does not store signals associated with poor channel conditions.

[0163] In some aspects, the control node 605 may utilize feedback communications to select a repeater node 610 from a plurality of repeater nodes 610. For example, a communication may be sent to a plurality of candidate repeater nodes 610. Each candidate repeater node 610 may send a feedback communication to the control node 605 indicating the quality or power of a signal received by the candidate repeater node 610. The control node 605 may utilize the feedback communications to select the candidate repeater node 610 indicating the highest channel condition value in the feedback communications. In some aspects, the control node 605 may utilize the feedback communications to select a candidate repeater node 610 from one or more candidate repeater nodes 610 that provided ACK feedback.

[0164] As shown in reference numeral 645, control node 605 can send and repeater node 610 can receive the updated configuration for retransmitting operation based at least in part on feedback communication.As mentioned above, in some respects, control node 605 can send the indication of continuing to forward communication or the indication of not continuing to forward communication to repeater node 610.In some respects, control node 605 can send the indication of the updated configuration that repeater node 610 will use when forwarding communication to repeater node 610.In some respects, control node 605 can send the indication of the updated configuration that repeater node 610 will use when forwarding future communication to repeater node 610.In some respects, control node 605 can send the indication of the updated configuration that repeater node 610 will use when forwarding future communication to repeater node 610 and have selected repeater node 610 to forward communication from one or more other candidate repeater nodes 610 to repeater node 610.

[0165] As shown at reference numeral 650, the repeater node 610 may perform digital processing operations to regenerate a communicated signal (e.g., as described above with respect to Figure 5 As shown in FIG. 6A , the repeater node 610 may transmit and the wireless node 615 may receive the regenerated signal of the communication. Alternatively, the repeater node 610 may transmit the regenerated signal of the communication to the control node 605 .

[0166] Thus, when a communication is received by the repeater node 610, the control node 605 may be enabled to determine channel conditions associated with the communication. The feedback communication enables the control node 605 to make improved configuration and / or scheduling decisions for the repeater node 610. Thus, network performance is improved because the control node 605 can ensure that the repeater node 610 is scheduled and / or configured to forward the communication based at least in part on feedback associated with the communication.

[0167] As pointed out above, Figure 6 are provided as examples. Other examples may be related to Figure 6 Different than described.

[0168] Figure 7 is a diagram illustrating an example 700 associated with a feedback report of a repeater according to the present disclosure. Figure 7 As shown, a control node, a repeater node, and one or more wireless nodes can communicate with each other in a wireless network, such as the wireless network 100. In some aspects, the control node can be the control node 605, the control node 510, the control node 410, the first wireless node 305, the second wireless node 315, etc. In some aspects, the repeater node can be the repeater node 610, the repeater node 505, the repeater node 405, the repeater node 310, etc. In some aspects, the wireless node can be the wireless node 615, the wireless node 515, the wireless node 415, the first wireless node 305, the second wireless node 315, etc.

[0169] Figure 7 A situation is depicted in which a control node sends a downlink signal to be forwarded by a repeater node in accordance with a retransmission operation. In some aspects, the downlink signal may be sent by another wireless node that is aware of the repeater node (e.g., the repeater node may be a wireless node that is aware of the repeater node). Figure 7 (Controlled by a third device not shown in FIG).

[0170] As indicated by reference numeral 705, the control node may transmit a PDCCH communication. The PDCCH communication may be a forward PDCCH communication (e.g., a PDCCH communication transmitted using a forward link). The PDCCH communication may schedule a downlink signal (e.g., a forward downlink signal) to be forwarded by the repeater node. In some aspects, the PDCCH communication may indicate a configuration of a retransmission operation to be performed by the repeater node (e.g., may indicate resources associated with the retransmission operation, a transmission configuration, a beamforming configuration, etc.). In some aspects, the PDCCH communication may indicate a feedback configuration that indicates how the repeater node provides feedback to the control node.

[0171] As shown in reference numeral 710, the control node (or another wireless node) may transmit and the repeater node may receive a downlink signal to be forwarded by the repeater node. The repeater node may perform measurements associated with the received downlink signal. For example, the repeater node may determine one or more channel condition values ​​associated with the received downlink signal.

[0172] As shown by reference numeral 715, the repeater node may send, and the control node may receive, feedback communications associated with the downlink signal. The feedback communication may be ACK / NACK feedback indicating a channel condition associated with the received downlink signal. In some aspects, the feedback communication may include a measurement report indicating at least one of a measured received power, a measured received quality, or one or more channel condition values ​​associated with the received downlink signal.

Figure 7 In some aspects, the repeater node may send the feedback communication after forwarding the uplink signal to the control node or another wireless node (e.g., after the operations described below with respect to reference numeral 850).

[0184] As shown in reference numeral 840, the control node may send a PDCCH communication based at least in part on the feedback communication. For example, the PDCCH communication may indicate to the repeater node whether to continue or not to forward the uplink signal. In some aspects, the PDCCH communication may indicate an updated configuration for the retransmission operation (e.g., an updated configuration that the repeater node will use when sending the regenerated uplink signal, an updated configuration that the repeater node will use for future communications, etc.). In some aspects, the PDCCH communication may schedule and / or configure the repeater node to transmit the regenerated uplink signal. In some aspects, the control node may not send the PDCCH communication after receiving the feedback communication. For example, if the feedback communication indicates that the received uplink signal is associated with good channel conditions (e.g., ACK feedback, etc.), the control node may not send the PDCCH communication, and the repeater node may continue the retransmission operation normally.
