Adaptive augmented reality transmission for ultra-wideband communications

Abstract

Ultra-wideband frequencies for augmented reality (XR) services operate as unlicensed spectrum, which may lead to accidental interference. Although some link adaptation procedures may be used, uncertain link quality may result in sub-optimal utilization of spectrum resources, which may result in poor performance of XR services. Some aspects described herein enable a fixed number of retransmissions to be used for data for XR frames, wherein each of the retransmissions has a different XR frame quality or a different number of parity bits. The XR device may transmit a feedback message indicating whether the first transmission is successful, and may receive a second transmission with additional data for the XR frame. In this manner, the XR device may ensure more efficient use of network resources.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This patent application claims priority to U.S. non-provisional patent application No. 18 / 158,187, filed on January 23, 2023, entitled “ADAPTIVE EXTENDED REALITY TRANSMISSIONS FOR ULTRA-WIDE BAND COMMUNICATIONS,” and assigned to the assignee of the present application. The disclosure of the prior application is considered a part of and incorporated by reference into the present patent application. Technical Field

[0003] Aspects of the present disclosure relate generally to wireless communications, and to techniques and apparatus for adaptive extended reality (XR) transmission for ultra-wideband communications. Background Art

[0004] Wireless communication systems are widely deployed to provide a variety of telecommunication services, such as telephony, video, data, messaging, and broadcasts. Typical wireless communication systems 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), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency division multiple access (OFDMA), single-carrier frequency division multiple access (SC-FDMA), time division synchronous code division multiple access (TD-SCDMA), 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 one or more network nodes that support communication for wireless communication devices, such as user equipment (UE) or multiple UEs. A UE may communicate with a network node via downlink and uplink communications. A "downlink" (or "DL") refers to the communication link from a network node to a UE, and an "uplink" (or "UL") refers to the communication link from a UE to a network node. Some wireless networks may support device-to-device communication, such as via a local link (e.g., a sidelink (SL), a wireless local area network (WLAN) link, and / or a wireless personal area network (WPAN) link, etc.).

[0006] These multiple access technologies have been adopted in various telecommunications standards to provide a common protocol that enables diverse user equipment (UEs) to communicate at the city, national, regional, and / or global levels. 5G, also referred to as New Radio (NR), is a set of enhancements to the LTE mobile standard promulgated by 3GPP. 5G is designed to better support mobile broadband internet access by using orthogonal frequency division multiplexing (OFDM) with a cyclic prefix (CP) (CP-OFDM) on the downlink and CP-OFDM and / or single-carrier frequency division multiplexing (SC-FDM) (also known as discrete Fourier transform-spread OFDM (DFT-s-OFDM)) on the uplink, as well as supporting beamforming, multiple-input, multiple-output (MIMO) antenna technology, and carrier aggregation. This improves spectral efficiency, reduces costs, improves services, utilizes new spectrum, and better integrates with other open standards. As demand for mobile broadband access continues to increase, further improvements to 4G, 5G, and other radio access technologies remain valuable. Summary of the Invention

[0007] An extended reality (XR) device may communicate with a network node and / or user equipment (UE) to obtain data associated with providing XR functionality, which may include XR data, frame data, or another type of data. The XR device may communicate with the UE on a side link to obtain data, which may reduce power consumption of the XR device relative to communicating with the network node on an access link. When communicating on the side link, the XR device and the UE may use ultra-wideband frequencies, such as frequencies in the range of approximately 6 gigahertz (GHz) to 10 GHz. These ultra-wideband frequencies may correspond to a portion of the frequency range designated as FR3, as described in more detail below. Ultra-wideband frequencies may enable the use of relatively large bandwidths, such as bandwidths of up to approximately 3 GHz, which may facilitate data transfer of large amounts of data associated with providing XR services.

[0008] However, these ultra-wideband frequencies operate as unlicensed spectrum, which can lead to unintended interference. While some link adaptation processes can be used, uncertain link quality can lead to suboptimal utilization of spectrum resources, potentially resulting in poor performance for XR services. Some aspects described herein enable the use of a fixed number of retransmissions for data for an XR frame, where each of these retransmissions has a different XR frame quality or a different number of parity bits. For example, an XR device may receive (e.g., from a UE) a first transmission comprising first data for an XR frame with a first frame quality (e.g., a first resolution) and a first number of parity bits. The XR device may send a feedback message indicating whether the first transmission was successful and may receive a second transmission with additional data for the XR frame. In this case, when the feedback message indicates successful reception of the first transmission, the additional data can be used to achieve a second frame quality (e.g., a second resolution) that is better than the first frame quality. Conversely, when the feedback message indicates failure of the first transmission, the additional data can be used to achieve a second number of parity bits. Overall, the first and second transmissions have a greater number of parity bits than the first transmission alone, thereby improving reliability. In this way, XR devices, UEs, and / or network nodes may ensure more efficient use of network resources and enable higher resolution XR services without introducing unpredictable delays in data delivery for the XR services.

[0009] Some aspects described herein relate to a method of wireless communication performed by an XR device.

[0030] The detailed description set forth below in conjunction with the accompanying drawings is intended as a description of various configurations and is not intended to represent configurations in which the concepts described herein may be practiced. The detailed description includes specific details for the purpose of providing a thorough understanding of the various concepts. However, it will be apparent to those skilled in the art that these concepts may be practiced without these specific details. In some instances, well-known structures and components are shown in block diagram form to avoid obscuring such concepts.

[0031] Several aspects of telecommunications systems will now be presented with reference to various apparatus and methods. These apparatus and methods are described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively, "elements"). These elements can be implemented using electronic hardware, computer software, or any 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] By way of example, a "processing system" that may include one or more processors implements an element, or any part of an element, or any combination of elements. Examples of processors include microprocessors, microcontrollers, digital signal processors (DSPs), field programmable gate arrays (FPGAs), programmable logic devices (PLDs), state machines, gated logic components, discrete hardware circuits, and other suitable hardware configured to perform the various functionalities described throughout this disclosure. One or more processors in a processing system can execute software. Software should be broadly interpreted to mean instructions, instruction sets, codes, code segments, program codes, programs, subroutines, software modules, applications, software applications, software packages, routines, subroutines, objects, executables, threads of execution, processes, functions, etc., regardless of whether they are referred to as software, firmware, middleware, microcode, hardware description languages, or other names.

[0033] Thus, in one or more example embodiments, the functions described may be implemented in hardware, software, firmware, or any combination thereof. If implemented in software, the functions may be stored or encoded as one or more instructions or codes on a computer-readable medium. Computer-readable media include computer storage media. A storage medium may be any available medium that can be accessed by a computer. By way of example, and not limitation, such computer-readable media may include random access memory (RAM), read-only memory (ROM), electrically erasable programmable ROM (EEPROM), compact disc ROM (CD-ROM), or other optical disc storage, magnetic disc storage, or other magnetic storage devices, combinations of the foregoing types of computer-readable media, or any other medium that can be used to store computer-executable code in the form of instructions or data structures that can be accessed by a computer.

[0034] Although various aspects may be described herein using terminology generally associated with 5G or New Radio (NR) radio access technology (RAT), various aspects of the present disclosure may be applicable to other RATs, such as 3G RATs, 4G RATs, and / or post-5G (e.g., 6G) RATs.

[0035] Figure 1 is a diagram illustrating an example of a wireless network 100. Wireless network 100 may be a 5G (e.g., NR) network or a 4G (e.g., Long Term Evolution (LTE)) network, or may include elements of a 5G (e.g., NR) network or a 4G (e.g., Long Term Evolution (LTE)) network, or the like. Wireless network 100 may include one or more network nodes 110 (illustrated as network node 110a, network node 110b, network node 110c, and network node 110d), user equipment (UE) 120 or multiple UEs 120 (illustrated as UE 120a, UE 120b, UE 120c, UE 120d, and UE 120e), or other entities. Network node 110 is an example of a network node that communicates with UE 120. As shown, network node 110 may include one or more network nodes. For example, the network node 110 may be a converged network node, meaning that the converged network node is configured to utilize a radio protocol stack that is physically or logically integrated within a single RAN node (e.g., within a single device or unit). As another example, the network node 110 may be a disaggregated network node (sometimes referred to as a disaggregated base station), meaning that the network node 110 is configured to utilize a protocol stack that is physically or logically distributed across two or more nodes (such as one or more central units (CUs), one or more distributed units (DUs), or one or more radio units (RUs)).

[0036] In some examples, network node 110 is or includes a network node (such as a RU) that communicates with UE 120 via a radio access link. In some examples, network node 110 is or includes a network node (such as a DU) that communicates with other network nodes 110 via a fronthaul link or a midhaul link. In some examples, network node 110 is or includes a network node (such as a CU) that communicates with other network nodes 110 via a midhaul link or with a core network via a backhaul link. In some examples, network node 110 (such as a converged network node 110 or a decomposed network node 110) may include multiple network nodes, such as one or more RUs, one or more CUs, and / or one or more DUs. For example, network node 110 may include an NR base station, an LTE base station, a Node B, an eNB (e.g., in 4G), a gNB (e.g., in 5G), an access point, a transmit receive point (TRP), a DU, a RU, a CU, a mobility element of a network, a core network node, a network element, network equipment, a RAN node, or a combination thereof. In some examples, network nodes 110 may be interconnected to each other or to one or more other network nodes 110 in wireless network 100 via various types of fronthaul interfaces, midhaul interfaces, and / or backhaul interfaces (such as direct physical connections, air interfaces, or virtual networks) using any suitable transport network.

[0037] In some examples, network node 110 may provide communication coverage for a particular geographic area. In the Third Generation Partnership Project (3GPP), the term "cell" can refer to the coverage area of network node 110 or a network node subsystem serving that coverage area, depending on the context in which the term is used. Network node 110 may provide communication coverage for a macrocell, a picocell, a femtocell, or another type of cell. A macrocell may cover a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by UEs 120 with service subscriptions. A picocell may cover a relatively small geographic area and may allow unrestricted access by UEs 120 with service subscriptions. A femtocell may cover a relatively small geographic area (e.g., a residence) and may allow restricted access by UEs 120 associated with the femtocell (e.g., UEs 120 in a Closed Subscriber Group (CSG)). A network node 110 for a macrocell may be referred to as a macro network node. A network node 110 for a picocell may be referred to as a pico network node. The network node 110 for a femto cell may be referred to as a femto network node or a home network node. Figure 1In the example shown, network node 110a may be a macro network node for macro cell 102a, network node 110b may be a pico network node for pico cell 102b, and network node 110c may be a femto network node for femto cell 102c. A network node may support one or more (e.g., three) cells. In some examples, the cells may not necessarily be stationary, and the geographic area of the cells may move depending on the location of a mobile network node 110 (e.g., a mobile network node).

[0038] In some aspects, the term "base station" or "network node" may refer to a converged base station, a disaggregated base station, an integrated access and backhaul (IAB) node, a relay node, or one or more components thereof. For example, in some aspects, a "base station" or "network node" may refer to a CU, DU, RU, a near real-time (near-RT) RAN intelligent controller (RIC), a non-real-time (non-RT) RIC, or a combination thereof. In some aspects, the term "base station" or "network node" may refer to a device configured to perform one or more functions, such as those described herein in conjunction with network node 110. In some aspects, the term "base station" or "network node" may refer to multiple devices configured to perform one or more functions. For example, in some distributed systems, each of multiple different devices (which may be located in the same or different geographic locations) may be configured to perform at least a portion of a function, or to perform at least a portion of the function repeatedly, and the term "base station" or "network node" may refer to any one or more of these different devices. In some aspects, the term "base station" or "network node" may refer to one or more virtual base stations or one or more virtual base station functions. For example, in some aspects, two or more base station functions may be instantiated on a single device. In some aspects, the term "base station" or "network node" may refer to one of the base station functions but not another base station function. In this way, a single device may include more than one base station.

[0039] The wireless network 100 may include one or more relay stations. A relay station is a network node that receives transmissions of data from an upstream node (e.g., a network node 110 or a UE 120) and transmits the transmissions of data to a downstream node (e.g., a UE 120 or a network node 110). A relay station may be a UE 120 that can relay transmissions for other UEs 120. Figure 1 In the illustrated example, a network node 110 d (e.g., a relay network node) may communicate with a network node 110 a (e.g., a macro network node) and a UE 120 d to facilitate communications between the network node 110 a and the UE 120 d. A network node 110 that relays communications may be referred to as a relay station, a relay base station, a relay network node, a relay node, a relay, or the like.

[0040] The wireless network 100 may be a heterogeneous network that includes different types of network nodes 110, such as macro network nodes, pico network nodes, femto network nodes, or relay network nodes. These different types of network nodes 110 may have different transmit power levels, different coverage areas, or different impacts on interference in the wireless network 100. For example, a macro network node may have a high transmit power level (e.g., 5 watts to 40 watts), while a pico network node, a femto network node, and a relay network node may have a lower transmit power level (e.g., 0.1 watt to 2 watts).

[0041] The network controller 130 may be coupled to or in communication with a set of network nodes 110 and may provide coordination and control for the network nodes 110. The network controller 130 may communicate with the network nodes 110 via a backhaul communication link or a midhaul communication link. The network nodes 110 may also communicate directly with each other or indirectly via a wireless backhaul communication link or a wired backhaul communication link. In some aspects, the network controller 130 may be or may include a CU or a core network device.

[0042] UEs 120 may be dispersed throughout wireless network 100, and each UE 120 may be stationary or mobile. UEs 120 may include, for example, access terminals, terminals, mobile stations, or subscriber units. UEs 120 may be cellular phones (e.g., smartphones), personal digital assistants (PDAs), wireless modems, wireless communication devices, handheld devices, laptop computers, cordless phones, wireless local loop (WLL) stations, tablet devices, cameras, gaming devices, netbooks, smartbooks, ultrabooks, medical devices, biometric devices, wearable devices (e.g., smart watches, smart clothing, smart glasses, smart wristbands, smart jewelry (e.g., smart rings or smart bands)), entertainment devices (e.g., music devices, video devices, or satellite radios), in-vehicle components or sensors, smart meters / sensors, industrial manufacturing equipment, global positioning system equipment, UE functionality of a network node, or any other suitable device configured to communicate via a wireless or wired medium.

[0043] Some UEs 120 may be considered machine-type communication (MTC) or evolved or enhanced machine-type communication (eMTC) UEs. MTC UEs or eMTC UEs may include, for example, robots, drones, remote devices, sensors, meters, monitors, or location tags, which may communicate with a network node, another device (e.g., a remote device), or some other entity. Some UEs 120 may be considered Internet of Things (IoT) devices or implemented as NB-IoT (Narrowband IoT) devices. Some UEs 120 may be considered customer premises equipment. UE 120 may be included within a housing that houses components of UE 120, such as a processor component or a memory component. In some examples, 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 operatively coupled, communicatively coupled, electronically coupled, or electrically coupled.

[0044] In some examples, wireless network 100 may include extended reality (XR) devices 170. For example, XR devices 170 may communicate with network node 110 (e.g., via an access link) and / or UE 120 (e.g., via a side link). In some examples, XR devices 170 may be examples of UE 120. In other words, some UEs 120 may be XR devices 170. XR functionality may include augmented reality (AR), virtual reality (VR), mixed reality (MR), and the like. For example, when providing XR services, XR devices 170 may provide rendering data via a display (e.g., a screen, a set of VR goggles, a heads-up display, or another type of display).

[0045] Generally speaking, any number of wireless networks 100 may be deployed in a given geographic area. Each wireless network 100 may support a specific RAT and may operate on one or more frequencies. A RAT may also be referred to as a radio technology or air interface. A frequency may also be referred to as a carrier or frequency channel. Each frequency in a given geographic area may support a single RAT to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed.

[0046] In some examples, 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 network node 110 as an intermediary for communicating with each other). For example, UEs 120 can communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, or vehicle-to-pedestrian (V2P) protocols), or mesh networks. In such examples, UEs 120 can perform scheduling operations, resource selection operations, or other operations described elsewhere herein as being performed by network node 110.

[0047] Devices of the wireless network 100 may communicate using an electromagnetic spectrum, which may be subdivided into various categories, bands, or channels by frequency or wavelength. For example, devices of the wireless network 100 may communicate using one or more operating frequency bands. In 5G NR, two initial operating frequency bands have been identified as frequency range designations FR1 (410 MHz–7.125 GHz) and FR2 (24.25 GHz–52.6 GHz). Although a portion of FR1 is greater than 6 GHz, FR1 is often (interchangeably) referred to as the “sub-6 GHz” band in various documents and articles. A similar naming issue sometimes occurs with respect to FR2, which is often (interchangeably) referred to as the “millimeter wave” band in documents and articles, although it is distinct from the extremely high frequency (EHF) band (30 GHz–300 GHz) identified as the “millimeter wave” band by the International Telecommunication Union (ITU).

[0048] Frequencies between FR1 and FR2 are generally referred to as mid-band frequencies. Recent 5G NR research has identified the operating band for these mid-band frequencies as frequency range designation FR3 (7.125 GHz–24.25 GHz). Frequency bands falling within FR3 may inherit either FR1 characteristics or FR2 characteristics, and thereby effectively extend the features of FR1 or FR2 to mid-band frequencies. In addition, higher frequency bands are currently being explored to extend 5G NR operation beyond 52.6 GHz. For example, three higher operating bands have been identified as frequency range designations FR4a or FR4-1 (52.6 GHz–71 GHz), FR4 (52.6 GHz–114.25 GHz), and FR5 (114.25 GHz–300 GHz). Each of these higher frequency bands falls within the EHF band.

[0049] With these examples in mind, unless otherwise specified, if the term "sub-6 GHz" is used herein, it may broadly refer to frequencies that may be less than 6 GHz, frequencies that may be within FR1, or frequencies that may include mid-band frequencies. Furthermore, unless otherwise specified, if the term "millimeter wave" is used herein, it may broadly refer to frequencies that may include mid-band frequencies, frequencies that may be within FR2, FR4, FR4-a, FR4-1, or FR5, or frequencies that may be within the EHF band. It is contemplated that the frequencies included in these operating bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, or FR5) may be modified, and that the techniques described herein are applicable to those modified frequency ranges.

[0050] In some aspects, the XR device 170 may include a communication manager 172. As described in greater detail elsewhere herein, the communication manager 172 may receive, via an ultra-wideband connection, a first transmission conveying first data for a frame, the first data associated with a first XR frame quality and a first number of parity bits; send a feedback message based at least in part on receiving the first transmission; and receive, via the ultra-wideband connection and based at least in part on sending the feedback message, a second message conveying second data for the frame, the second data associated with a second XR frame quality and a second number of parity bits. Additionally or alternatively, the communication manager 172 may perform one or more other operations described herein.

[0051] In some aspects, UE 120 may include a communications manager 140. As described in greater detail elsewhere herein, communications manager 140 may transmit, via an ultra-wideband connection, a first message conveying first data for a frame, the first data associated with a first XR frame quality and a first number of parity bits; receive a feedback message based at least in part on transmitting the first message; and transmit, via the ultra-wideband connection and based at least in part on receiving the feedback message, a second transmission conveying second data for the frame, the second data associated with a second XR frame quality and a second number of parity bits. Additionally or alternatively, communications manager 140 may perform one or more other operations described herein.

[0052] In some aspects, the network node 110 may include a communication manager 150. As described in greater detail elsewhere herein, the communication manager 150 may transmit, via an ultra-wideband connection, a first message conveying first data for a frame, the first data associated with a first XR frame quality and a first number of parity bits; receive a feedback message based at least in part on transmitting the first message; and transmit, via the ultra-wideband connection and based at least in part on receiving the feedback message, a second message conveying second data for the frame, the second data associated with a second XR frame quality and a second number of parity bits. Additionally or alternatively, the communication manager 140 may perform one or more other operations described herein.

[0053] As indicated above, Figure 1 are provided as examples. Other examples can be found in the Figure 1 The examples described are different.

[0054] Figure 2 2 is a diagram illustrating example 200 of a network node 110 communicating with a UE 120 or an XR device 170 in a wireless network 100. The network node 110 may be equipped with a set of antennas 234a through 234t, such as T antennas (T ≥ 1). The UE 120 or XR device 170 may be equipped with a set of antennas 252a through 252r, such as R antennas (R ≥ 1). The network node 110 of example 200 includes one or more radio frequency components, such as antennas 234 and a modem 232. In some examples, the network node 110 may include an interface, a communication component, or another component that facilitates communication with the UE 120, the XR device 170, or another network node. Some network nodes 110 may not include radio frequency components, such as one or more CUs or one or more DUs, that facilitate direct communication with the UE 120 or XR device 170.

[0055] At the network node 110, the transmit processor 220 may receive data intended for a UE 120 or an XR device 170 (or a set of UEs 120 or a set of XR devices 170) from a data source 212. The transmit processor 220 may use one or more channel quality indicators (CQIs) received from the UE 120 or XR device 170 to select one or more modulation and coding schemes (MCSs) for the UE 120 or XR device 170. The network node 110 may process (e.g., encode and modulate) the data for the UE 120 or XR device 170 using the MCS selected for the UE 120 or XR device 170 and may provide data symbols for the UE 120 or XR device 170. The transmit processor 220 may process system information (e.g., for semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, or upper layer signaling) and provide overhead symbols and control symbols. The transmit processor 220 may 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)). The transmit (TX) multiple-input, multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on data symbols, control symbols, overhead symbols, or reference symbols, as applicable, and may provide a set of output symbol streams (e.g., T output symbol streams) to a corresponding set of modems 232 (e.g., T modems) (shown as modems 232a through 232t). For example, each output symbol stream may be provided to a modulator component (shown as MOD) of the modem 232. Each modem 232 may process a corresponding output symbol stream (e.g., for OFDM) using a corresponding modulator component to obtain an output sample stream. Each modem 232 may also process (e.g., convert to analog, amplify, filter, or upconvert) the output sample stream using a corresponding modulator component to obtain a downlink signal. The modems 232a through 232t may transmit a set of downlink signals (eg, T downlink signals) via a corresponding set of antennas 234 (eg, T antennas) (shown as antennas 234a through 234t).

[0056] At the UE 120 or XR device 170, a set of antennas 252 (shown as antennas 252a through 252r) may receive downlink signals from the network node 110 or other network nodes 110 and may provide a set of received signals (e.g., R received signals) to a set of modems 254 (e.g., R modems) (shown as modems 254a through 254r). For example, each received signal may be provided to a demodulator component (shown as DEMOD) of the modem 254. Each modem 254 may use a corresponding demodulator component to condition (e.g., filter, amplify, downconvert, or digitize) the received signal to obtain input samples. Each modem 254 may use the demodulator component to further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector 256 may obtain received symbols from the modem 254, perform MIMO detection on the received symbols where applicable, and provide detected symbols. The receive (RX) processor 258 may process (e.g., demodulate and decode) the detected symbols, may provide decoded data for the UE 120 or XR device 170 to the data sink 260, and may provide decoded control information and system information to the 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, or a CQI parameter, among other parameters. In some examples, one or more components of the UE 120 or XR device 170 may be included in a housing.

[0057] 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 network node 110 via the communication unit 294.

[0058] One or more antennas (e.g., antennas 234a to 234t or antennas 252a to 252r) may include or may be included within one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, or one or more antenna arrays. An antenna panel, antenna group, set of antenna elements, or antenna array may include one or more antenna elements (in a single housing or multiple housings), a set of coplanar antenna elements, a set of non-coplanar antenna elements, or may be coupled to one or more transmit or receive components (such as a Figure 2 One or more antenna elements of one or more components).

[0059] On the uplink, at the UE 120 or XR device 170, the transmit processor 264 may receive and process data from a data source 262 and control information (e.g., for reports including RSRP, RSSI, RSRQ, or CQI) from the controller / processor 280. The transmit processor 264 may generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be pre-decoded by the TX MIMO processor 266, if applicable, further processed by the modem 254 (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to the network node 110. In some examples, the modem 254 of the UE 120 or XR device 170 may include a modulator and a demodulator. In some examples, the UE 120 or XR device 170 may include a transceiver. The transceiver may include any combination of an antenna 252, a modem 254, a MIMO detector 256, a receive processor 258, a transmit processor 264, or a TX MIMO processor 266. The transceiver may be used by a processor (eg, controller / processor 280 ) and memory 282 to perform aspects of any of the processes described herein.

[0060] At the network node 110, uplink signals from a UE 120 or XR device 170 or other UEs may be received by an antenna 234, processed by a modem 232 (e.g., a demodulator component (shown as DEMOD) of the modem 232), detected by a MIMO detector 236 (if applicable), and further processed by a receive processor 238 to obtain decoded data and control information transmitted by the UE 120 or XR device 170. The receive processor 238 may provide the decoded data to a data sink 239 and the decoded control information to a controller / processor 240. The network node 110 may include a communication unit 244 and may communicate with the network controller 130 via the communication unit 244. The network node 110 may include a scheduler 246 to schedule one or more UEs 120 for downlink or uplink communications. In some examples, the modem 232 of the network node 110 may include a modulator and a demodulator. In some examples, the network node 110 includes a transceiver. The transceiver may include any combination of antenna 234, modem 232, MIMO detector 236, receive processor 238, transmit processor 220, or TX MIMO processor 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to perform aspects of any of the processes described herein.

[0061] The controller / processor 240 of the network node 110, the controller / processor 280 of the UE 120 or the XR device 170, and / or Figure 2Any other component of the controller / processor 240 of the network node 110, the controller / processor 280 of the UE 120 or the XR device 170, and / or Figure 2 Any other component of the may perform or direct e.g. Figure 6 Method 600, Figure 7 700 and / or operations of other processes as described herein. Memory 242 and memory 282 may store data and program codes for network node 110 and UE 120 or XR device 170, respectively. In some examples, memory 242 and / or memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, the one or more instructions, when executed (e.g., directly or after compilation, conversion, and / or interpretation) by one or more processors of network node 110, UE 120, and / or XR device 170, may cause the one or more processors, UE 120, XR device 170, and / or network node 110 to perform or direct, for example, Figure 6 Method 600, Figure 7 The method 700 and / or operations of other processes as described herein. In some examples, executing instructions may include running instructions, converting instructions, compiling instructions, and / or interpreting instructions, among other things.

[0062] In some aspects, the XR device 170 includes: means for receiving, via an ultra-wideband connection, a first transmission conveying first data for a frame, the first data associated with a first XR frame quality and a first number of parity bits; means for sending a feedback message based at least in part on receiving the first transmission; and / or means for receiving, via the ultra-wideband connection and based at least in part on sending the feedback message, a second transmission conveying second data for the frame, the second data associated with a second XR frame quality and a second number of parity bits. In some aspects, means for the XR device 170 to perform the operations described herein may include, for example, one or more of the communication manager 172, the antenna 252, the modem 254, the MIMO detector 256, the receive processor 258, the transmit processor 264, the TX MIMO processor 266, the controller / processor 280, or the memory 282.

[0063] In some aspects, the UE 120 includes: means for transmitting, via an ultra-wideband connection, a first message conveying first data for a frame, the first data associated with a first XR frame quality and a first number of parity bits; means for receiving a feedback message based at least in part on transmitting the first message; and / or means for transmitting, via the ultra-wideband connection and based at least in part on receiving the feedback message, a second message conveying second data for the frame, the second data associated with a second XR frame quality and a second number of parity bits. Means for the UE 120 to perform the operations described herein may include, for example, one or more of the communications manager 140, the antenna 252, the modem 254, the MIMO detector 256, the receive processor 258, the transmit processor 264, the TX MIMO processor 266, the controller / processor 280, or the memory 282.

[0064] In some aspects, the network node 110 includes: means for transmitting, via an ultra-wideband connection, a first message conveying first data for a frame, the first data associated with a first XR frame quality and a first number of parity bits; means for receiving a feedback message based at least in part on transmitting the first message; and / or means for transmitting, via the ultra-wideband connection and based at least in part on receiving the feedback message, a second message conveying second data for the frame, the second data associated with a second XR frame quality and a second number of parity bits. In some aspects, means for the network node 110 to perform the operations described herein may include, for example, one or more of the communication manager 150, the transmit processor 220, the TX MIMO processor 230, the modem 232, the antenna 234, the MIMO detector 236, the receive processor 238, the controller / processor 240, the memory 242, or the scheduler 246.

[0065] Although Figure 2 The blocks in FIG. 2 are illustrated as distinct components, but the functionality described above with respect to these blocks may be implemented in a single hardware, software, or combined component or in various combinations of components. For example, the functionality described with respect to the transmit processor 264, the receive processor 258, and / or the TX MIMO processor 266 may be performed by or under the control of the controller / processor 280.

[0066] As indicated above, Figure 2 are provided as examples. Other examples can be found in the Figure 2 The examples described are different.

[0067] The deployment of a communication system (such as a 5G NR system) can be arranged in a variety of ways with various components or parts. In a 5G NR system or network, a network node, a network entity, a mobility element of the network, a RAN node, a core network node, a network element, a base station, or network equipment can be implemented in a converged architecture or a disaggregated architecture. For example, a base station (such as a Node B (NB), an evolved NB (eNB), an NR base station, a 5G NB, an access point (AP), a TRP, or a cell, etc.) or one or more units (or one or more components) performing base station functionality can be implemented as a converged base station (also known as a standalone base station or a single-chip base station) or a disaggregated base station. A "network entity" or "network node" can refer to a disaggregated base station or one or more units of a disaggregated base station (such as one or more CUs, one or more DUs, one or more RUs, or a combination thereof).

[0068] A converged base station (e.g., a converged network node) can be configured to utilize a radio protocol stack that is physically or logically integrated within a single RAN node (e.g., within a single device or unit). A decomposed base station (e.g., a decomposed network node) can be configured to utilize a protocol stack that is physically or logically distributed between two or more units (such as one or more CUs, one or more DUs, or one or more RUs). In some examples, the CU can be implemented within a network node, and one or more DUs can be co-located with the CU, or alternatively, can be geographically or virtually spread across one or more other network nodes. The DU can be implemented to communicate with one or more RUs. Each of the CU, DU, and RU can also be implemented as a virtual unit, such as a virtual central unit (VCU), a virtual distributed unit (VDU), or a virtual radio unit (VRU), among others.

[0069] Base station type operation or network design may take into account the aggregated nature of base station functionality. For example, a disaggregated base station may be utilized in an IAB network, an open radio access network (O-RAN (such as the network configuration initiated by the O-RAN Alliance)), or a virtualized radio access network (vRAN, also known as a cloud radio access network (C-RAN)) to facilitate scalability of the communication system by separating base station functionality into one or more independently deployable units. A disaggregated base station may include functionality implemented across two or more units at various physical locations, as well as functionality implemented virtually for at least one unit, which enables flexibility in network design. Each unit of the disaggregated base station may be configured for wired or wireless communication with at least one other unit of the disaggregated base station.

[0070] Figure 3FIG2 is a diagram illustrating an example disaggregated base station architecture 300 according to the present disclosure. The disaggregated base station architecture 300 may include a CU 310, which may communicate directly with a core network 320 via a backhaul link, or indirectly with the core network 320 through one or more disaggregated control units (such as a near-RT RIC 325 via an E2 link, a non-RT RIC 315 associated with a service management and orchestration (SMO) framework 305, or both). The CU 310 may communicate with one or more DUs 330 via respective midhaul links (such as via an F1 interface). Each of the DUs 330 may communicate with one or more RUs 340 via respective fronthaul links. Each of the RUs 340 may communicate with one or more UEs 120 or XR devices 170 via respective radio frequency (RF) access links. In some implementations, a UE 120 may be served simultaneously by multiple RUs 340.

[0071] Each of the units (including the CU 310, DU 330, and RU 340), as well as the near-RT RIC 325, the non-RT RIC 315, and the SMO framework 305, may include or be coupled to one or more interfaces configured to receive or transmit signals, data, or information (collectively, signals) via a wired or wireless transmission medium. Each of the units, or an associated processor or controller that provides instructions to the one or more communication interfaces of the corresponding unit, may be configured to communicate with one or more of the other units via the transmission medium. In some examples, each of the units may include a wired interface configured to receive signals or transmit signals to one or more of the other units via the wired transmission medium, and a wireless interface that may include a receiver, transmitter, or transceiver (such as an RF transceiver) configured to receive signals or transmit signals to one or more of the other units via the wireless transmission medium, or both.

[0072] In some aspects, the CU 310 may host one or more higher-layer control functions. Such control functions may include radio resource control (RRC) functions, packet data convergence protocol (PDCP) functions, or service data adaptation protocol (SDAP) functions, among others. Each control function may be implemented using an interface configured to communicate signals with other control functions hosted by the CU 310. The CU 310 may be configured to handle user plane functionality (e.g., central unit-user plane (CU-UP) functionality), control plane functionality (e.g., central unit-control plane (CU-CP) functionality), or a combination thereof. In some implementations, the CU 310 may be logically split into one or more CU-UP units and one or more CU-CP units. When implemented in an O-RAN configuration, the CU-UP units may communicate bidirectionally with the CU-CP units via an interface, such as the E1 interface. As needed, the CU 310 may be implemented to communicate with the DU 330 for network control and signaling.

[0073] Each DU 330 may correspond to a logical unit that includes one or more base station functions for controlling the operation of one or more RUs 340. In some aspects, a DU 330 may host one or more of a radio link control (RLC) layer, a medium access control (MAC) layer, and one or more higher physical (PHY) layers, at least in part according to a functional split (such as that defined by 3GPP). In some aspects, the one or more higher PHY layers may be implemented by one or more modules for forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, and the like. In some aspects, a DU 330 may also host one or more lower PHY layers, such as those implemented by one or more modules for fast Fourier transform (FFT), inverse FFT (iFFT), digital beamforming, or physical random access channel (PRACH) extraction and filtering. Each layer (which may also be referred to as a module) may be implemented using an interface configured to communicate signals with other layers (and modules) hosted by the DU 330 or with control functions hosted by the CU 310.

[0074] Each RU 340 may implement lower layer functionality. In some deployments, the RU 340 controlled by the DU 330 may correspond to a logical node that hosts RF processing functions or low PHY layer functions such as performing FFT, performing iFFT, digital beamforming, or PRACH extraction and filtering, etc. based on a functional split (e.g., a functional split defined by 3GPP) (such as a lower layer functional split). In such an architecture, each RU 340 may be operated to handle over-the-air (OTA) communications with one or more UEs 120 or XR devices 170. In some implementations, the real-time and non-real-time aspects of communicating with the control plane and user plane of the RU 340 may be controlled by the corresponding DU 330. In some scenarios, this configuration may enable each DU 330 and CU 310 to be implemented in a cloud-based RAN architecture (such as a vRAN architecture).

[0075] The SMO framework 305 can be configured to support RAN deployment and provisioning of both non-virtualized and virtualized network elements. For non-virtualized network elements, the SMO framework 305 can be configured to support the deployment of dedicated physical resources for RAN coverage requirements, which can be managed via an operations and maintenance interface (such as the O1 interface). For virtualized network elements, the SMO framework 305 can be configured to interact with a cloud computing platform (such as the Open Cloud (O-Cloud) platform 390) to perform network element lifecycle management (such as instantiating virtualized network elements) via cloud computing platform interfaces (such as the O2 interface). Such virtualized network elements may include, but are not limited to, the CU 310, DU 330, RU 340, non-RT RIC 315, and near-RT RIC 325. In some implementations, the SMO framework 305 can communicate with hardware aspects of the 4G RAN (such as the Open eNB (O-eNB) 311) via the O1 interface. Additionally, in some implementations, the SMO framework 305 can communicate directly with each of the one or more RUs 340 via a corresponding O1 interface. The SMO framework 305 can also include a non-RT RIC 315 configured to support the functionality of the SMO framework 305.

[0076] The non-RT RIC 315 can be configured to include logic that enables non-real-time control and optimization of RAN elements and resources, artificial intelligence / machine learning (AI / ML) workflows including model training and updating, or policy-based guidance of applications / features in the near-RT RIC 325. The non-RT RIC 315 can be coupled to or in communication with the near-RT RIC 325 (e.g., via an A1 interface). The near-RT RIC 325 can be configured to include logic that enables near-real-time control and optimization of RAN elements and resources through data collection and actions via an interface (e.g., via an E2 interface) that connects one or more CUs 310, one or more DUs 330, or both, and the O-eNB with the near-RT RIC 325.

[0077] In some implementations, to generate AI / ML models to be deployed in the near-RT RIC 325, the non-RT RIC 315 may receive parameters or external enrichment information from an external server. Such information may be utilized by the near-RT RIC 325 and may be received from non-network data sources or from network functions at the SMO framework 305 or the non-RT RIC 315. In some examples, the non-RT RIC 315 or the near-RT RIC 325 may be configured to tune RAN behavior or performance. For example, the non-RT RIC 315 may monitor long-term trends and patterns in performance and employ AI / ML models to perform corrective actions through the SMO framework 305 (such as via reconfiguration of the O1 interface) or through the creation of RAN management policies (such as A1 interface policies).

[0078] As indicated above, Figure 3 are provided as examples. Other examples can be found in the Figure 3 The examples described are different.

[0079] Figure 4 is a diagram illustrating an example 400 of sidelink and access link communications according to the present disclosure.

[0080] like Figure 4 As shown, UE 120 and XR device 170 can communicate with each other via a side link, as described above in conjunction with Figure 4As further shown, in some sidelink modes, the network node 110 may communicate with the UE 120 (e.g., directly or via one or more network nodes), such as via a first access link. Additionally or alternatively, in some sidelink modes, the network node 110 may communicate with the XR device 170 (e.g., directly or via one or more network nodes), such as via a second access link. Thus, the direct link between the UE 120 and the XR device 170 (e.g., via an interface) may be referred to as a sidelink, and the direct link between the network 110 and the UE 120 or XR device 170 (e.g., via a Uu interface) may be referred to as an access link. Sidelink communications may be sent via the sidelink, and access link communications may be sent via the access link. Access link communications may be downlink communications (from the network node 110 to the UE 120 or XR device 170) or uplink communications (from the UE 120 or XR device 170 to the network node 110).

[0081] As indicated above, Figure 4 are provided as examples. Other examples can be found in the Figure 4 The examples described are different.

[0082] When communicating on the sidelink, XR devices and UEs may use ultra-wideband (UWB) frequencies, such as those in the range of approximately 6 GHz to 10 GHz. These UWB frequencies may be part of FR3, as described above. UWB frequencies operate as unlicensed spectrum, which can result in unintended interference, uncertain link quality, and / or suboptimal utilization of spectrum resources. Considering the use of unlicensed spectrum for high-bandwidth communications (e.g., XR services), one technique for link adaptation is to adapt video quality based at least in part on channel conditions. In other words, the XR device may receive high-quality video when channel quality is high (e.g., from the UE) and low-quality video when channel quality is low. The "Shannon limit" or "Shannon bound" may refer to the maximum rate at which data can be transmitted given the channel bandwidth and noise characteristics of the channel. The Shannon limit provides a theoretical limit on video quality that varies depending on instantaneous channel conditions. Achieving a video quality indication closer to the Shannon limit results in more efficient utilization of available channel resources than when video quality is less close to the Shannon limit.

[0083] To achieve the aforementioned changes in video quality as channel quality varies, a communication system may have multiple streams with unequal error protection. For example, a UE may have a first level of protection for first video data having a first bitrate and a second level of protection for video data having a second bitrate. In this case, the granularity of the first video data may be lower than that of the second video data, and the first bitrate may be more robust than the second bitrate. In this case, the UE transmits multiple streams (e.g., to convey the first video data and the second video data). The XR device attempts to decode as many video streams as possible (e.g., a first video stream conveying the first data and a second video stream conveying the second data). When both the first data and the second data are decoded, the XR device can provide an XR service with relatively high frame quality (e.g., relatively high video quality). When only the first data can be decoded (e.g., based at least in part on the first data having more robust protection than the second data), the XR device can still provide an XR service, but with relatively lower frame quality. Although described with respect to two data streams, many data streams may have different levels of granularity corresponding to different video resolutions and / or XR frame qualities.

[0084] However, transmitting multiple streams with unequal error protection can result in suboptimal video quality (e.g., video quality that is relatively far from the Shannon limit across a set of different channel quality characteristics). Therefore, some aspects described herein implement adaptive XR transmission rates for ultra-wideband communication. For example, an XR device may receive a set of transmissions for an XR frame based at least in part on feedback transmissions, where the set of transmissions differ in XR frame quality and / or parity bits. In this case, the XR device may receive a first transmission with first data for the XR frame and transmit a feedback message indicating whether the first transmission was successfully received. In this case, if the first transmission is successful, the XR device receives second data for the XR frame with finer granularity (e.g., resulting in higher XR frame quality when combined with the first and second data than could be achieved from the first data alone). Alternatively, if the first transmission is unsuccessful, the XR device receives the second data with additional parity bits (e.g., to increase the likelihood that the XR device successfully decodes the second data and can provide the XR frame despite unsuccessful reception of the first transmission). In this case, the number of retransmissions of data associated with the same XR frame can be a fixed number, which can avoid unpredictable delays in providing XR frames (e.g., for display) compared to using an adaptively determined number of retransmissions. In this way, the XR device can provide XR frame quality that is closer to the Shannon limit than achieved through other techniques, thereby indicating a more efficient or optimal use of network resources.

[0085] Certain aspects described herein enable the use of a fixed number of retransmissions for data for an XR frame, where each of these retransmissions has a different XR frame quality or a different number of parity bits. For example, an XR device may receive (e.g., from a UE) a first transmission including first data for an XR frame with a first frame quality (e.g., a first resolution) and a first number of parity bits. The XR device may send a feedback message indicating whether the first transmission was successful and may receive a second transmission with additional data for the XR frame. In this case, when the feedback message indicates successful reception of the first transmission, the additional data may be used to achieve a second frame quality (e.g., a second resolution) that is better than the first frame quality. Conversely, when the feedback message indicates failure of the first transmission, the additional data may be used to achieve a second number of parity bits that is greater than the first number of parity bits. In this manner, the XR device, UE, and / or network node can ensure more efficient use of network resources and enable higher-resolution XR services without introducing unpredictable delays in the delivery of data for the XR services.

[0086] Figures 5A to 5C is a diagram illustrating an example 500 associated with adaptive XR transmission rate for ultra-wideband communication according to the present disclosure. Figure 5A As shown, example 500 includes communications between network node 110 , UE 120 , and XR device 170 .

[0087] like Figure 5A As further shown and at 505, UE 120 may receive frame data from network node 110. For example, UE 120 may receive information associated with providing an XR frame for display at XR device 170 in conjunction with an XR service. In some aspects, the frame data may be deconstructed or divided into multiple data sets associated with the frame. For example, network node 110 may process the XR frame to divide the data associated with the XR frame into multiple data sets having different granularities. The different granularities may refer to different characteristics of the XR frame that are conveyed with each transmission of each data set.

[0088] In other words, different granularities may refer to different resolutions, such as a first data set of first data representing a frame at a first, low resolution, a second data set of second data representing a frame at a second, medium resolution (alone or in combination with the first data), and a third data set of third data representing a frame at a third, high resolution (alone or in combination with the first data and / or the second data). In another example, different data sets may convey different fields of view, such as a first data set conveying first data associated with rendering an XR frame with a relatively narrow field of view, a second data set conveying second data associated with rendering an XR frame with a relatively medium field of view, and a third data set conveying third data associated with rendering an XR frame with a relatively wide field of view. Additionally or alternatively, the different data sets may differ in another attribute, such as shading, shading, depth of field, amount of information, or another attribute that can be divided into multiple granularities.

[0089] In some aspects, the network node 110 may transmit data associated with an XR frame without deconstructing or segmenting the data. For example, the network node 110 may transmit data to the UE 120, and the UE 120 may deconstruct the data for transmission across multiple transmissions to the XR device 170. In this case, the XR device 170 may deconstruct the data based at least in part on channel conditions, channel bandwidth, XR device 170 capabilities, subcarrier spacing, video rate, channel latency, feedback latency associated with feedback transmission (as described below), or latency requirements of the XR service, etc.

[0090] In some aspects, the network node 110 may transmit information identifying a configuration for the UE 120 and the XR device 170 to use for transmitting data associated with the XR service. For example, the network node 110 may transmit configuration information identifying the number of transmissions for each frame, the set of source redundancy versions for each frame, the size of the source redundancy versions, a reconstruction rule for reconstructing each frame, a set of channel redundancy versions (e.g., which may have equal or unequal sizes, may be adaptively determined, signaled, or fixed, or may be frequency band specific or applicable to multiple frequency bands), whether retransmissions may be intermixed with new information (e.g., whether a retransmission for a first frame may be included in the same transmission as a new transmission for a second frame), the type of gap to capacity feedback that may be used, or transmitter behavior for capacity gap signaling, etc., as described in more detail below. Additionally or alternatively, one or more parameters of the configuration information may be statically defined for the UE 120 and / or the XR device 170 (e.g., in a specification). Additionally or alternatively, UE 120 may select one or more parameters of the configuration information (eg, without network node 110 or based at least in part on some available parameter set identified by network node 110 ) and signal the one or more parameters to XR device 170 .

[0091] like Figure 5A As further shown and at 510, the XR device 170 may receive a first transmission from the UE 120. For example, the XR device 170 may receive a first transmission conveying first data for a particular frame associated with the XR service. In some aspects, the first transmission may include first data associated with a first XR characteristic. For example, the first data may be associated with a first frame quality (such as a first resolution, a first field of view, first shading, first shading, first depth of field, or first information content, etc.).

[0092] like Figure 5A As further shown and at 520, the XR device 170 may send a feedback message to the UE 120. For example, the XR device 170 may send a hybrid automatic repeat request (HARQ) feedback message to convey information indicating whether the first transmission was successfully received and decoded (e.g., a HARQ acknowledgement (ACK)) or unsuccessfully received and decoded (e.g., a HARQ negative acknowledgement (NACK)).

[0093] like Figure 5A As further shown and at 530, the XR device 170 may receive a second transmission from the UE 120. For example, the XR device 170 may receive a second transmission conveying second data for a particular frame associated with the XR service. In some aspects, the second transmission may include second data associated with a second XR characteristic. For example, the second data may be associated with a second frame quality (such as a second resolution, a second field of view, a second shading, a second shading, a second depth of field, or a second information content, etc.). Additionally or alternatively, the second transmission may include second data associated with a second reliability level. For example, the first transmission may include a first number of parity bits for incremental redundancy (IR) HARQ (IR-HARQ), and the second transmission may include a second number of parity bits for IR-HARQ.

[0094] In some aspects, UE 120 may generate a second transmission that differs from the first transmission in a manner based at least in part on the content of the feedback message. For example, when UE 120 receives a HARQ ACK message, UE 120 may transmit a second transmission that includes additional bits in the second data for conveying finer granularity data for a particular frame (e.g., higher frame quality or resolution relative to the first data conveyed in the first transmission). Conversely, when UE 120 receives a HARQ NACK message, UE 120 may transmit a second transmission that includes additional bits in the second data for conveying additional parity bits for a particular frame (e.g., to increase the likelihood of successful reception and decoding relative to the first transmission).

[0095] Figure 5B and Figure 5C An example of the resending mentioned above is shown. Figure 5B As shown, a first transmission from UE 120 to XR device 170 may include content SORV0, where S represents the source redundancy version (e.g., the content of a particular frame being delivered) and RV represents the channel redundancy version (RV) of the particular frame. Figure 5B As further shown, when UE 120 receives a HARQ NACK as a response to the first transmission, UE 120 sends a second transmission with content S0RV1 (e.g., the same frame content, but a higher RV, which indicates more parity bits). Conversely, when UE 120 receives a HARQ ACK as a response to the first transmission, UE 120 sends a second transmission with content S1RV0, which indicates finer-grained data for a particular frame and the same redundancy version as the first transmission. Similarly, for the third transmission, UE 120 may send S2RV0 after receiving another HARQ ACK for the second transmission (which itself is based at least in part on the received HARQ ACK). Conversely, for the third transmission based on a NACK for the first transmission (Tx1) and an ACK for the second transmission (Tx2), UE 120 may send content S1RV0. 0+1 In this case, content S0 is not successfully delivered in Tx1, but is delivered in Tx2. In addition, Tx2 uses redundancy version RV1 based on the fact that Tx1 did not successfully use redundancy version RV0. In Tx3, UE 120 uses redundancy version RV1. 0+1 , which means that UE 120 uses both RV0 and RV1 for Tx3, where the number of source bits S is reduced to accommodate the additional parity bits.

[0096] Figure 5C An example of a feedback loop for decoding transmissions at the UE 120 is shown. For example, redundancy versions RV0, RV1, or RV2 are generated by channel decoding and stored in a buffer. RV0 is read from the buffer and transmitted, and if a HARQ NACK is received, RV1 is read from the buffer and transmitted. Conversely, when a HARQ ACK is received, S1 is encoded and replaces the contents of the buffer (e.g., the S0-related RV is removed and the S1-related RV is stored in the buffer as a replacement). In some aspects, as shown, RVs of unequal size may be used to represent different (unequal) amounts of channel adaptation performed after each consecutive HARQ feedback message. Although Figures 5A to 5C It is described in terms of two or three transmissions (which may also be referred to as "retransmissions" or "repeats"), but another number of transmissions are contemplated.

[0097] In some aspects, the UE 120 may combine the transmission of digital data with the transmission of analog data. For example, the UE 120 may split the channel bandwidth of the channel used for the second transmission into a first bandwidth of 1 / b and a second bandwidth of (b-1) / b, where b is based at least in part on channel conditions and / or a requested peak signal-to-noise ratio (pSNR), such as b = log(pSNR) / log(1+SNR). In this case, the UE 120 may use a first transmit chain (e.g., a digital transmit chain) to process and transmit a first portion of the second transmission, and a second transmit chain (e.g., an analog transmit chain) to process and transmit a second portion of the second transmission (e.g., using frequency division multiplexing (FDM) or another technique). By combining the use of combined digital and analog decoding with retransmissions of varying granularity, as described above, the UE 120 and the XR device 170 may use network resources more efficiently (e.g., closer to the Shannon limit).

[0098] In some aspects, UE 120 may include redundant versions of data at different granularities to fill the resources of a time slot. For example, for a second transmission, UE 120 may include a first redundant version of first data having a first frame quality and a second redundant version of second data having a second frame resolution to fill a data container (e.g., resources of one time slot for the second transmission). In this case, UE 120 may use a data code rate that matches the aggregate code rate of the retransmitted data. Additionally or alternatively, UE 120 may include data associated with multiple frames in a single transmission. For example, UE 120 may include, in a second transmission, a retransmission of first data for a first frame and a new transmission of first data for a second frame.

[0099] In some aspects, UE 120 may determine a capacity gap or decoding gap. The capacity gap or decoding gap may refer to the amount of redundancy transmitted to ensure decoder success (e.g., based at least in part on channel characteristics, such as normalized signal-to-noise ratio (SNR), which measures how close running a given coding scheme is to successful decoding). When the XR device 170 is about to send a HARQ NACK in response to a first transmission, the capacity gap may be calculated, for example, at the XR device 170 and signaled as feedback to the UE 120. In this case, the code rate for the next transmission (e.g., the second transmission) by the UE 120 may be based at least in part on the capacity gap. In some aspects, the code rate may be adaptively determined based at least in part on the capacity gap (e.g., based on a particular frequency band), thereby enabling adaptation to varying degrees of unknown channel conditions. By determining the code rate based at least in part on the capacity gap, the UE 120 may ensure that the XR device 170 has a relatively high probability of successfully decoding the second transmission. In this case, UE 120 may transmit a third transmission to provide a finer level of granularity for a particular frame, and may use the same code rate for the third transmission as achieved by the combination of the first and second transmissions.

[0100] like Figure 5A As further shown and at 540, the XR device 170 may reconstruct the frame. For example, the XR device 170 may reconstruct a particular frame using the first data from the first transmission, the second data from the second transmission, and / or the nth data from the nth transmission, and so on. In this case, the XR device 170 may combine the successfully decoded first data from the first transmission with the successfully decoded second data from the second transmission (which may be a residual of the first data from the first transmission) to provide a relatively high-resolution frame. Conversely, when the first transmission was not successfully decoded but the second transmission was successfully decoded, the XR device 170 may reconstruct the particular frame from the first data retransmitted in the second transmission to provide a relatively low-resolution frame. In some aspects, the XR device 170 may split the data by frame. For example, the XR device 170 may receive data for a first frame and data for a second frame in the same transmission, as described above, and may split the data to construct the first frame and the second frame, respectively.

[0101] As indicated above, Figures 5A to 5C are provided as examples. Other examples can be found in the Figures 5A to 5C The examples described are different.

[0102] Figure 6 6 is a flow diagram of an example method 600 of wireless communication. The method 600 may be performed, for example, by an XR device (eg, XR device 170).

[0103] At 610, the XR device may receive a first transmission conveying first data for a frame. For example, the XR device (e.g., using Figure 8 The communication manager 172 and / or receiving component 802 depicted in FIG may receive, via an ultra-wideband connection, a first transmission conveying first data for a frame, the first data being associated with a first XR frame quality and a first number of parity bits, as described above in connection with, for example Figure 5A and as described at 510. In some aspects, the number of retransmissions for a frame is a fixed number that applies to each frame in a set of frames that includes the frame.

[0104] At 620, the XR device may send a feedback message based at least in part on receiving the first transmission. For example, the XR device (e.g., using Figure 8 The communication manager 172 and / or sending component 804 depicted in FIG may send a feedback message based at least in part on receiving the first transmission, as described above in conjunction with, for example, Figure 5A and as described at 520. In some aspects, the feedback message is an acknowledgment message, and the first data is associated with a first XR frame quality and the second data is associated with a second XR frame quality, the second data being based at least in part on a residual of the first data. In some aspects, the feedback message is a negative acknowledgment message, and the first data is associated with a first number of parity bits and the second data is associated with a second number of parity bits.

[0105] At 630, the XR device may receive a second transmission conveying second data for the frame. For example, the XR device (e.g., using Figure 8 The communication manager 172 and / or receiving component 802 depicted in FIG may receive, via the ultra-wideband connection and based at least in part on transmitting the feedback message, a second transmission conveying second data for the frame, the second data being associated with a second XR frame quality and a second number of parity bits, as described above in connection with, for example Figure 5A and as described at 530 .

[0106] In some aspects, the first XR frame quality is different from the second XR frame quality. In some aspects, the first number of parity bits is different from the second number of parity bits. In some aspects, the second data includes more data than the first data, and the additional data of the second data relative to the first data is used to implement additional XR data associated with the second XR frame quality relative to the first XR frame quality or additional parity bits associated with the second number of parity bits relative to the first number of parity bits. In some aspects, the channel bandwidth of the ultra-wideband connection includes a first sub-bandwidth for transmitting digital data associated with the frame and a second sub-bandwidth for transmitting analog data associated with the frame, the digital data and the analog data associated with the frame including the first data and the second data. In some aspects, the second transmission includes a first set of resources for conveying the second data for the frame and a second set of resources for conveying third data associated with another frame.

[0107] In some aspects, the data code rate of the second transmission is based at least in part on an aggregate code rate of the first transmission and the second transmission. In some aspects, the size of the second transmission is based at least in part on a capacity gap associated with the first transmission. In some aspects, the third transmission that conveys third data for the frame is associated with a third XR frame quality and a combined data code rate of the first transmission and the second transmission. In some aspects, the one or more parameters associated with the configuration of the first transmission or the second transmission include predetermined parameters or signaled parameters associated with at least one of the following: a number of transmissions for a frame, a source redundancy version for a frame, a channel redundancy version for a frame, a number of frames for which data is conveyed in each transmission, or capacity gap feedback for a frame.

[0108] At 640, in some aspects, the XR device may reconstruct the frame based at least in part on the first data and the second data. For example, the XR device (e.g., using Figure 8 The communication manager 172 and / or receiving component 802 depicted in FIG may reconstruct the frame as described above in conjunction with, for example Figure 5A and as described at 540 .

[0109] although Figure 6 Example blocks of method 600 are shown, but in some aspects, method 600 may include Figure 6 The blocks depicted in the method 600 may include additional blocks, fewer blocks, different blocks, or blocks arranged in a different manner than those depicted in the method 600. Additionally or alternatively, two or more of the blocks in the method 600 may be executed in parallel.

[0110] Figure 77 is a flow chart of an example method 700 of wireless communication. The method 700 may be performed by, for example, a UE (eg, UE 120). In another example, the method 700 may be performed by another device (such as a network node (eg, network node 110)).

[0111] At 710, the UE may send a first message conveying first data for a frame. For example, the UE (e.g., using Figure 10 The communication manager 140 and / or the sending component 1004 depicted in FIG may send a first message conveying first data for a frame via an ultra-wideband connection, the first data being associated with a first XR frame quality and a first number of parity bits, as described above in connection with, for example Figure 5A and as described at 510. In some aspects, the number of retransmissions for a frame is a fixed number applicable to each frame in a set of frames that includes the frame. In some aspects, a channel bandwidth of the ultra-wideband connection includes a first sub-bandwidth for transmitting digital data associated with the frame and a second sub-bandwidth for transmitting analog data associated with the frame, the digital data and the analog data associated with the frame including first data and second data.

[0112] At 720, the UE may receive a feedback message based at least in part on sending the first message. Figure 10 The communication manager 140 and / or receiving component 1002 depicted in FIG may receive a feedback message based at least in part on sending the first message, as described above in conjunction with, for example, Figure 5A and as described at 520. In some aspects, the feedback message is an acknowledgment message, and the first data is associated with a first XR frame quality and the second data is associated with a second XR frame quality, the second data being based at least in part on a residual of the first data. In some aspects, the feedback message is a negative acknowledgment message, and the first data is associated with a first number of parity bits and the second data is associated with a second number of parity bits.

[0113] At 730, the UE may send a second message conveying second data for the frame. For example, the UE (e.g., using Figure 10 The communication manager 140 and / or transmitting component 1004 depicted in FIG may transmit, via the ultra-wideband connection and based at least in part on receiving the feedback message, a second message conveying second data for the frame, the second data being associated with a second XR frame quality and a second number of parity bits, as described above in connection with, for example Figure 5Aand as described at 530. In some aspects, the first XR frame quality is different from the second XR frame quality. In some aspects, the first number of parity bits is different from the second number of parity bits. In some aspects, the second data includes more data than the first data, and the additional data of the second data relative to the first data is used to implement additional XR data associated with the second XR frame quality relative to the first XR frame quality or additional parity bits associated with the second number of parity bits relative to the first number of parity bits.

[0114] In some aspects, the second message includes a first set of resources for conveying second data for the frame and a second set of resources for conveying third data related to another frame. In some aspects, the data code rate of the second message is based at least in part on the aggregate code rate of the first message and the second message. In some aspects, the size of the second message is based at least in part on the capacity gap associated with the first message. In some aspects, the third message conveying the third data for the frame is associated with the third XR frame quality and the combined data code rate of the first message and the second message. In some aspects, one or more parameters associated with the configuration of the first message or the second message include predetermined parameters or signaled parameters, the configuration being associated with at least one of: the number of messages for the frame, the source redundancy version for the frame, the channel redundancy version for the frame, the number of frames whose data is conveyed in each message, or capacity gap feedback for the frame.

Additionally or alternatively, two or more of the blocks in the method 700 may be executed in parallel.

[0122] Figure 9 is a diagram illustrating an example 900 of a hardware implementation for an apparatus 905 employing a processing system 910 according to the present disclosure. The apparatus 905 may be an XR device.
