Description

Technical Field

[0001] All aspects of this disclosure relate to wireless communication in general, and more specifically to techniques, apparatus and methods associated with communication of feedback information from environmental Internet of Things (IoT) devices. Background Technology

[0002] Wireless communication systems are widely deployed to provide a variety of services, including voice, text, messaging, video, data, and / or other services. Services may include unicast, multicast, and / or broadcast services, etc. Typical wireless communication systems employ multiple access radio access technologies (RATs) capable of supporting communication with multiple users by sharing available system resources (e.g., time-domain resources, frequency-domain resources, spatial-domain resources, and / or device transmit power, etc.). Examples of such multiple access RATs 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, and Time Division Synchronous Code Division Multiple Access (TD-SCDMA) systems.

[0003] The aforementioned Multiple Access RATs have been adopted in various telecommunications standards to provide a common protocol enabling different wireless communication devices to communicate at the city, national, regional, or global level. An example telecommunications standard is New Radio (NR). NR (also known as 5G) is part of the continuous evolution of mobile broadband announced by the 3rd Generation Partnership Project (3GPP). NR (and other mobile broadband evolutions beyond NR) can be designed to better support the Internet of Things (IoT) and reduced-capacity device deployments, industrial connectivity, millimeter-wave (mmWave) expansion, licensed and unlicensed spectrum access, non-terrestrial network (NTN) deployments, sidelinks and other device-to-device direct communication technologies (e.g., cellular vehicle-to-everything (CV2X) communications), massive MIMO, decomposed network architectures and network topology expansion, multi-subscriber implementations, high-precision positioning and / or radio frequency (RF) sensing, and more. As the demand for mobile broadband access continues to grow, further improvements to NR can be implemented, and other radio access technologies (such as 6G) can be introduced to further advance mobile broadband evolution.

[0004] For environmental Internet of Things (IoT) communications, the physical forward link (FL) data channel can be used to transmit FL (or downlink (DL)) data from a wireless communication device acting as a reader (e.g., network node 110 or UE 120) to the environmental IoT device. In practice, feedback information associated with a given FL communication (e.g., acknowledgment (ACK) or negative acknowledgment (NACK) messages, etc.) should be provided by the environmental IoT device. Generally, the purpose of such feedback information is to indicate the transmission status of a given FL communication (e.g., ACK messages indicating that the FL communication was successfully received and processed by the environmental IoT device; NACK messages; retransmission requests; or retransmission requests, etc.). Therefore, it is necessary to define the manner in which feedback information associated with one or more FL communications is conveyed so that such feedback information supports data integrity and reliable communication for the environmental IoT device.

[0036] Various aspects of this disclosure are described below with reference to the accompanying drawings. However, aspects of this disclosure may be embodied in many different forms and should not be construed as limited to any specific aspect illustrated or described with reference to the drawings or otherwise presented in this disclosure. Rather, these aspects are provided so that this disclosure will be comprehensive and complete, and will fully convey the scope of protection of this disclosure to those skilled in the art. Those skilled in the art will understand that the scope of this disclosure is intended to cover any aspect of this disclosure disclosed herein, whether implemented independently of or in combination with any other aspect of this disclosure. For example, various combinations or numbers of aspects set forth herein may be used to implement an apparatus or a practice. Furthermore, the scope of this disclosure is intended to cover apparatuses having structures and / or functionalities other than those available for practicing the various aspects of this disclosure set forth herein, or methods practiced using these other structures and / or functionalities. Any aspect of this disclosure disclosed herein may be embodied by one or more elements of the claims.

[0037] Various methods, operations, apparatuses, and techniques will now be presented with reference to them. These methods, operations, apparatuses, and techniques will be described in detail below and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, or algorithms (collectively, “elements”). These elements may be implemented using hardware, software, or a combination of hardware and software. Whether such elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the system as a whole.

[0038] Environmental Internet of Things (IoT) devices may include endpoints such as radio frequency identification (RFID) devices, tags, or similar devices. Environmental IoT devices can be classified into at least three types: Device 1, Device 2a, and Device 2b. Device 1 type environmental IoT devices may have a peak power consumption of approximately 1 (a) milliwatt (μW), support energy storage, and use up to 1 / 10,000,000 of their capacity. X Initial sampling frequency offset (SFO) (ppm) (e.g., where X (It can be any suitable value), and uplink (UL) or reverse link (BL) transmission is communicated via backscattering of an externally provided carrier (CW). Both "Device 2a" and "Device 2b" type environmental IoT devices can have peak power consumption of less than or equal to several hundred μW, support energy storage, and use up to 10 X The initial SFO in ppm. Environmental IoT devices of type "Device 2a" can transmit UL / BL link transmissions via backscattering of externally provided CW. Environmental IoT devices of type "Device 2b" can transmit UL / BL transmissions by generating UL / BL transmissions internally.

[0039] For environmental IoT communications, the physical forward link (FL) data channel can be used to transmit DL / FL data from a wireless communication device acting as a reader (e.g., network node 110 or UE 120) to the environmental IoT device. In practice, feedback information associated with a given DL / FL communication (e.g., acknowledgment (ACK) or negative acknowledgment (NACK) messages, etc.) should be provided by the environmental IoT device. Generally, the purpose of such feedback information is to indicate the transmission status of a given DL / FL communication (e.g., ACK messages indicating that the DL / FL communication was successfully received and processed by the environmental IoT device; NACK messages; retransmission requests; or retransmission requests, etc.). Therefore, it is necessary to define the manner in which feedback information associated with one or more DL / FL communications is conveyed so that such feedback information supports data integrity and reliable communication for the environmental IoT device.

[0040] The overall scope involves the communication of feedback information from environmental IoT devices. Some aspects are more specifically related to the reception and transmission of feedback information that supports environmental IoT communication. In some aspects, environmental IoT devices generate feedback information associated with one or more DL / FL communications to be transmitted by the environmental IoT devices and send the feedback information to wireless communication devices.

[0041] In some examples, feedback information is conveyed independently of the UL / BL data associated with the physical UL / BL data channel. In some such aspects, feedback information may include ACK-only information, NACK-only information, or some combination of ACK and NACK information. In some aspects, feedback information is based on per TB transmitted per UL / BL. That is, in some aspects, the environmental IoT device may generate feedback information per TB of per UL / BL communication. In some aspects, feedback information transmitted per TB per UL / BL may include (units or multiple bits) a payload-based indication or a sequence-based indication. Alternatively, in some aspects, feedback information may be based on multiple TBs transmitted per UL / BL. That is, in some aspects, the environmental IoT device may generate feedback information for multiple TBs of per UL / BL communication. In some aspects, feedback information transmitted per multiple TB per UL / BL may include a single feedback information item associated with those multiple TBs. Alternatively, feedback information transmitted per multiple TB per UL / BL may include multiple feedback information items, each of which corresponds to a corresponding TB within those multiple TBs. That is, in some respects, feedback information can independently include confirmation information for each TB.

[0042] In some examples, feedback information is multiplexed with UL / BL data associated with the physical UL / BL data channel. In some aspects, feedback information may be multiplexed with UL / BL data based on a predefined number of bits of feedback information permitted to be multiplexed with UL / BL data. That is, in some aspects, the number of bits of feedback information that can be multiplexed with UL / BL data may be predefined. In some aspects, feedback information may be multiplexed with UL / BL data based on the number of bits of feedback information permitted to be multiplexed with UL / BL data, wherein the indication of the number of bits is received in DL / FL communication. That is, in some aspects, DL / FL communication can be used to dynamically indicate the number of bits of feedback information that can be multiplexed with UL / BL data. In some aspects, feedback information may be multiplexed with UL / BL data at least in part based on the number of DL / FL communications for which feedback information is to be provided. Therefore, in some aspects, the number of bits available for feedback information may be implicitly indicated at least in part based on the number of DL / FL communications that need to be acknowledged. In some such aspects, the number of DL / FL communications for which feedback information is to be provided may be determined using a minimum time interval and a counter.

[0043] Specific aspects of the subject matter described in this disclosure can be implemented to achieve one or more of the following potential advantages. In some examples, by implementing the transmission and reception of feedback information associated with one or more DL / FL communications, the described techniques can be used to convey feedback information (e.g., ACK information, NACK information, or retransmission requests, etc.) to support reliable and efficient DL / FL communication for IoT devices in an environment.

[0044] Transmitting environmental IoT feedback information associated with one or more DL / FL communications independently of the UL / BL data associated with the physical UL / BL data channel improves reliability, efficiency, and network performance. For example, transmitting environmental IoT feedback information independently of UL / BL data enhances transmission reliability by ensuring clear and rapid reception of feedback information even when the UL / BL data is experiencing interference or poor signal quality, thereby improving data transmission reliability by allowing for faster detection and retransmission of lost or corrupted data. As another example, transmitting environmental IoT feedback information independently of UL / BL data reduces latency by decreasing the time required to receive feedback information, thus reducing overall latency. As yet another example, transmitting environmental IoT feedback information independently of UL / BL data improves transmission success rate by allowing different modulation and decoding schemes compared to the UL / BL data to be used for feedback information, which in turn improves the success rate of feedback information reception.

[0045] Multiplexing environmental IoT feedback information associated with one or more DL / FL communications with UL / BL data associated with the physical UL / BL data channel can improve spectrum efficiency, reduce overhead, and improve the data transmission process. For example, multiplexing environmental IoT feedback information associated with one or more DL / FL communications with UL / BL data can improve spectrum efficiency by enabling the network to utilize available spectrum more efficiently. As another example, multiplexing environmental IoT feedback information associated with one or more DL / FL communications with UL / BL data can reduce overhead by, for example, eliminating the need for headers and other information that consume network resources. As another example, multiplexing environmental IoT feedback information associated with one or more DL / FL communications with UL / BL data can enhance resource allocation by allowing the network to allocate resources for a single transmission that includes both data and feedback information, thereby simplifying the scheduling process and potentially reducing latency in providing feedback information. As another example, multiplexing environmental IoT feedback information associated with one or more DL / FL communications with UL / BL data can improve the power efficiency of environmental IoT devices by reducing the number of transmissions by environmental IoT devices, thereby saving battery life.

[0046] Multiple access radio access technology (RAT) has been adopted in various telecommunications standards to provide a common protocol that enables different wireless communication devices to communicate at the city, national, regional, or global level. For example, 5G New Radio (NR) is part of the continuous mobile broadband evolution program released by the 3rd Generation Partnership Project (3GPP). 5G NR supports a variety of technologies and use cases, including enhanced mobile broadband (eMBB), ultra-reliable low-latency communication (URLLC), massive machine-type communication (mMTC), millimeter wave (mmWave) technology, beamforming, network slicing, edge computing, IoT connectivity and management, and network function virtualization (NFV).

[0047] With increasing demand for broadband access and the evolution of technologies supported by wireless communication networks, further technological improvements can be adopted or implemented in 5G NR or future RATs (such as 6G) to further advance the evolution of wireless communication for a variety of existing and new use cases and applications. Such technological improvements can be associated with new frequency band extensions, licensed and unlicensed spectrum access, overlapping spectrum use, small cell deployments, non-terrestrial network (NTN) deployments, decomposed network architectures and network topology extensions, device aggregation, advanced duplex communication, sidelinks and other device-to-device direct communication, IoT (including passive or ambient IoT) networks, reduced-capacity (RedCap) UE functionality, industrial connectivity, multi-subscriber implementations, high-precision positioning, radio frequency (RF) sensing and / or artificial intelligence or machine learning (AI / ML), and more. Such technological improvements can support use cases such as wireless backhaul, wireless data centers, extended reality (XR) and metaverse applications, meta-services for supporting vehicle connectivity, holographic and mixed reality communications, autonomous and collaborative robots, vehicle platooning and collaborative manipulation, sensor networks, posture monitoring, brain-computer interfaces, digital twin applications, asset management, and general coverage applications using off-ground and / or aerial platforms, etc. The methods, operations, apparatuses, and techniques described herein can implement one or more of the foregoing technologies and / or support one or more of the foregoing use cases.

[0048] Figure 1 This is an illustration of an example of a wireless communication network 100. The wireless communication network 100 may be a 5G (or NR) network or a 6G network, or may include elements of a 5G (or NR) network or a 6G network, etc. The wireless communication network 100 may include multiple network nodes 110, shown as network node (NN) 110a, network node 110b, network node 110c, and network node 110d. Network nodes 110 may support communication with multiple UEs 120 (shown as UE 120a, UE 120b, UE 120c, UE 120d, and UE 120e).

[0049] Network nodes 110 and UEs 120 of wireless communication network 100 can communicate using the electromagnetic spectrum, which can be subdivided into various categories, frequency bands, carriers, and / or channels according to frequency or wavelength. For example, devices of wireless communication network 100 can communicate using one or more operating frequency bands. In some aspects, multiple wireless communication networks 100 can be deployed in a given geographical area. Each wireless communication network 100 can support a specific RAT (which may also be referred to as an air interface) and can operate on one or more carrier frequencies in one or more frequency ranges. Examples of RATs include 4G RATs, 5G / NRRATs, and / or 6G RATs, etc. In some examples, when multiple RATs are deployed in a given geographical area, each RAT in that geographical area can operate on a different frequency to avoid interference with each other.

[0050] Various operating frequency bands have been defined as frequency ranges designated FR1 (410 MHz to 7.125 GHz), FR2 (24.25 GHz to 52.6 GHz), FR3 (7.125 GHz to 24.25 GHz), FR4a or FR4-1 (52.6 GHz to 71 GHz), FR4 (52.6 GHz to 114.25 GHz), and FR5 (114.25 GHz to 300 GHz). Although a portion of FR1 is greater than 6 GHz, in some documents and articles, FR1 is often (interchangeably) referred to as the “sub-6 GHz” band. Similarly, in some documents and articles, FR2 is often (interchangeably) referred to as the “millimeter wave” band, but this is different from the Very High Frequency (EHF) band (30 GHz to 300 GHz) identified as the “millimeter wave” band by the International Telecommunication Union (ITU). The frequencies between FR1 and FR2 are often referred to as the mid-band frequencies, including FR3. Frequency bands falling within FR3 can inherit FR1 or FR2 characteristics, thereby effectively extending the characteristics of FR1 or FR2 into mid-band frequencies. Therefore, "below 6 GHz" (if used herein) can broadly refer to frequencies less than 6 GHz, within FR1, and / or included in mid-band frequencies. Similarly, the term "millimeter wave" (if used herein) can broadly refer to frequencies included in mid-band frequencies, within FR2, FR4, FR4-a, FR4-1, or FR5, and / or within the EHF band. Higher frequency bands can extend 5G NR operation, 6G operation, and / or other RATs above 52.6 GHz. For example, each of FR4a, FR4-1, FR4, and FR5 falls within the EHF band. In some examples, wireless communication network 100 can implement dynamic spectrum sharing (DSS), where multiple RATs (e.g., 4G / LTE and 5G / NR) are implemented within a single frequency band using dynamic bandwidth allocation (e.g., based on user demand). It is conceivable that the frequencies included in these operating frequency bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1 and / or FR5) can be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0051] Network node 110 may include one or more devices, components, or systems that enable communication between UE 120 and one or more devices, components, or systems of wireless communication network 100. Network node 110 may be, may include, or may be referred to as: NR network node, 5G network node, 6G network node, node B, eNB, gNB, access point (AP), transmit / receive point (TRP), mobility element, core, network entity, network element, network equipment, and / or another type of device, component, or system included in the radio access network (RAN).

[0052] Network node 110 may be implemented as a single physical node (e.g., a single physical structure) or as two or more physical nodes (e.g., two or more different physical structures). For example, network node 110 may be a device or system implementing a portion of a radio protocol stack, a device or system implementing a complete protocol stack (such as a complete gNB protocol stack), or a collection of devices or systems collectively implementing a complete protocol stack. For example, and as shown, network node 110 may be an aggregated network node, meaning that network node 110 can implement a complete radio protocol stack physically and logically integrated within a single node (e.g., a single physical structure) in the wireless communication network 100. For example, aggregated network node 110 may consist of a single standalone base station or a single TRP that uses a complete radio protocol stack to implement or facilitate communication between UE 120 and the core network of wireless communication network 100.

[0053] Alternatively, and also as shown, network node 110 may be a decomposed network node (sometimes referred to as a decomposed base station), meaning that network node 110 may use protocol stacks that are physically distributed and / or logically distributed across two or more nodes in the same or different geographic locations. For example, a decomposed network node may have a decomposed architecture. In some deployments, decomposed network node 110 may be used in integrated access and backhaul (IAB) networks, in open radio access networks (O-RAN) (such as network configurations compliant with the O-RAN Alliance), or in virtualized radio access networks (vRAN) (also referred to as cloud radio access networks (C-RAN)) to facilitate scaling by decomposing base station functionality into multiple individually deployable units.

[0054] Network nodes 110 of the wireless communication network 100 may include one or more central units (Cu), one or more distributed units (Du), and / or one or more radio units (RU). CUs may host one or more higher-layer control functions, such as Radio Resource Control (RRC) functions, Packet Data Convergence Protocol (PDCP) functions, and / or Service Data Adaptation Protocol (SDAP) functions, etc. DUs may host one or more of the Radio Link Control (RLC) layer, Media Access Control (MAC) layer, and / or one or more higher physical (PHY) layers, at least in part, according to functional splits (such as those defined by 3GPP). In some examples, DUs may also host one or more low-PHY layer functions, such as Fast Fourier Transform (FFT), Inverse FFT (iFFT), beamforming, Physical Random Access Channel (PRACH) extraction and filtering, and / or scheduling of resources for one or more UEs 120, etc. RUs may host RF processing functions or low-PHY layer functions, such as FFT, iFFT, beamforming, or PRACH extraction and filtering, etc., according to functional splits (such as lower-layer functional splits). In this type of architecture, each RU can be operated to handle over-the-air (OTA) communications with one or more UE 120s.

[0055] In some aspects, a single network node 110 may include a combination of one or more Cu, one or more Du, and / or one or more RU. Additionally or alternatively, network node 110 may include one or more near real-time (near RT) RAN Intelligent Controllers (RICs) and / or one or more non-real-time (non-RT) RICs. In some examples, the CU, DU, and / or RU may be implemented as virtual units, such as Virtual Central Units (VCUs), Virtual Distributed Units (VDUs), or Virtual Radio Units (VRUs), etc. Virtual units may be implemented as virtual network functions, such as those associated with cloud deployments.

[0056] Some network nodes 110 (e.g., base stations, RUs, or TRPs) can provide communication coverage for specific geographic areas. In 3GPP, the term "cell" can refer to the coverage area of ​​network node 110 or to network node 110 itself, depending on the context in which the term is used. Network node 110 can support one or more (e.g., three) cells. In some examples, network node 110 can provide communication coverage for macro cells, pico cells, femto cells, or another type of cell. A macro cell can cover a relatively large geographic area (e.g., a radius of several kilometers) and can allow unrestricted access by UE 120 with a service subscription. A pico cell can cover a relatively small geographic area and can allow unrestricted access by UE 120 with a service subscription. A femto cell can cover a relatively small geographic area (e.g., a residential area) and can allow restricted access by UE 120 associated with that femto cell (e.g., UE 120 in a Closed Subscriber Group (CSG)). The network node 110 used for a macro cell may be referred to as a macro network node. The network node 110 used for a picocell can be referred to as a pico network node. The network node 110 used for a femtocell can be referred to as a femto network node or a home network node.

[0057] The wireless communication network 100 can be a heterogeneous network, comprising different types of network nodes 110, such as macro network nodes, piconet nodes, femtonet nodes, relay network nodes, aggregation network nodes, and / or decomposition network nodes, etc. Figure 1 In the example shown, network node 110a can be a macro network node for macro cell 130a, network node 110b can be a pico network node for pico cell 130b, and network node 110c can be a femto network node for femto cell 130c. Compared to other types of network nodes 110, the various types of network nodes 110 typically transmit at different power levels, serve different coverage areas, and / or have different effects on interference in the wireless communication network 100. For example, macro network nodes may have high transmit power levels (e.g., 5 watts to 40 watts), while pico network nodes, femto network nodes, and relay network nodes may have lower transmit power levels (e.g., 0.1 watts to 2 watts).

[0058] In some examples, network node 110 may be, may include, or may operate as a RU, TRP, or base station communicating with one or more UEs 120 via a radio access link (which may be referred to as a "Uu" link). The radio access link may include a downlink and an uplink. A "downlink" (or "DL") refers to the communication direction from network node 110 to UE 120, and an "uplink" (or "UL") refers to the communication direction from UE 120 to network node 110.

[0059] In some examples, any network node 110 relaying communication may be referred to as a relay network node, a relay station, or simply a repeater. A repeater may receive communications from an upstream station (e.g., another network node 110 or UE 120) and transmit communications to a downstream station (e.g., UE 120 or another network node 110). In this case, the wireless communication network 100 may include or be referred to as a "multi-hop network." Figure 1 In the example shown, network node 110d (e.g., a relay network node) can communicate with network node 110a (e.g., a macro network node) and UE 120d to facilitate communication between network node 110a and UE 120d. Additionally or alternatively, UE 120 can be a relay station capable of relaying transmissions to or from other UE 120s, or can operate as such a relay station. UE 120 relaying communication can be referred to as a UE repeater or relay UE, etc.

[0060] UE 120 may be physically distributed throughout the wireless communication network 100, and each UE 120 may be stationary or mobile. UE 120 may be, may include, an access terminal, another terminal, a mobile station, or a subscriber unit, or may be included in an access terminal, another terminal, a mobile station, or a subscriber unit. UE 120 may be, or may include, a cellular phone (e.g., a smartphone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet computer, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device, a biometric device, a wearable device (e.g., a smartwatch, smart clothing, smart glasses, a smart wristband and / or smart jewelry (such as a smart ring or smart bracelet)), an entertainment device (e.g., a music device, a video device and / or a satellite radio), an XR device, a vehicle component or sensor, a smart meter or sensor, industrial manufacturing equipment, a Global Navigation Satellite System (GNSS) device (such as a Global Positioning System device or another type of positioning device), a UE function of a network node, and / or any other suitable device or function that can communicate via a wireless medium, or may be coupled to them.

[0061] UE 120 and / or network node 110 may include one or more chips, system-on-a-chip (SoC), chipsets, packages, or devices that individually or collectively constitute or include a processing system. The processing system includes processor (or “processing”) circuitry in the form of one or more processors, microprocessors, processing units (such as central processing units (CPUs), graphics processing units (GPUs), neural processing units (NPUs), and / or digital signal processors (DSPs)), processing blocks, application-specific integrated circuits (ASICs), programmable logic devices (PLDs) (such as field-programmable gate arrays (FPGAs)), or other discrete gate or transistor logic components or circuits (all of which are generally referred to herein individually as “processors” or collectively as “processors” or “processor circuitry”). One or more of these processors may be individually or collectively configured to perform the various functions or operations described herein. A group of processors that can be configured or configured to perform a set of functions may include a first processor that can be configured or configured to perform a first function in the set, and a second processor that can be configured or configured to perform a second function in the set, or may include the entire group of processors that are configured or configured to perform the set of functions.

[0062] The processing system may also include memory circuitry in the form of one or more memory devices, memory blocks, memory elements, or other discrete gate or transistor logic components or circuits, each of which may include tangible storage media such as random access memory (RAM) or read-only memory (ROM) or combinations thereof (all of which are generally referred to herein individually as "memory" or collectively as "memory" or "memory circuitry"). One or more of these memories may be coupled to one or more processors in the processor (e.g., operatively coupled, communicatively coupled, electronically coupled, or electrically coupled) and may store processor-executable code (such as software) individually or collectively, which, when executed by one or more processors in the processor, may configure one or more processors in the processor to perform the various functions or operations described herein. Additionally or alternatively, in some examples, one or more processors in the processor may be pre-configured to perform the various functions or operations described herein without being configured by software. The processing system may also include or be coupled to one or more modems (such as Wi-Fi (e.g., IEEE compliant) modems or cellular (e.g., 3GPP 4G LTE, 5G, or 6G compliant) modems). In some embodiments, one or more processors of the processing system include or implement one or more modems among the modems. The processing system may also include, or be coupled to, multiple radio components (collectively, “radio components”), multiple RF chains, or multiple transceivers, each of which may in turn be coupled to one or more antennas among a plurality of antennas. In some embodiments, one or more processors of the processing system include or implement one or more of the radio components, RF chains, or transceivers. UE 120 may be included or may be contained in a housing that houses components associated with UE 120, including the processing system.

[0063] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) can communicate directly with each other using sidelink communication (e.g., without communicating through a network node 110 acting as an intermediary). As an example, UE 120a can directly send data, control information, or other signaling to UE 120e as sidelink communication. This contrasts with, for example, UE 120a first sending data to network node 110 in UL communication, and then that network node sending data to UE 120e in DL communication.

[0064] In some respects, the environmental IoT device 135 can be configured to communicate with network node 110 and / or UE 120. The environmental IoT device 135 is further described elsewhere in this document.

The transceiver may be under the control of and used by one or more processors (such as controller / processor 240), and in some respects, may perform aspects of the methods, procedures and / or operations described herein in conjunction with processor-readable code stored in memory 242. In some respects, network node 110 may include one or more interfaces, communication components and / or other components that facilitate communication with UE 120 or another network node.

[0071] The terms “processor,” “controller,” or “controller / processor” can refer to one or more controllers and / or one or more processors.

The reference to "one or more memories" should be understood to refer to any one or more memories of the corresponding device, such as those in conjunction with… Figure 2 The memory described. For example, an operation described as being performed by one or more memories can be performed by the same subset of the one or more memories or by different subsets of the one or more memories.

[0073] For downlink communication from network node 110 to UE 120, transmitting processor 214 may receive data (“downlink data”) intended for use by UE 120 (or a set of UEs including UE 120) from data source 212 (such as a data pipeline or data queue). In some examples, transmitting processor 214 may select one or more MCSs for UE 120 based on one or more Channel Quality Indicators (CQIs) received from UE 120. Network node 110 may process the data (e.g., including encoding the data) based on the MCS selected for UE 120 for transmission to UE 120 on the downlink, thereby generating data symbols. Transmitting processor 214 may process system information (e.g., semi-static resource partitioning information (SRPI)) and / or control information (e.g., CQI requests, grants, and / or upper-layer signaling) and provide overhead symbols and / or control symbols. The transmitting processor 214 can generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS), demodulation reference signals (DMRS), or channel state information (CSI) reference signals (CSI-RS)) and / or synchronization signals (e.g., primary synchronization signal (PSS) or secondary synchronization signal (SSS)).

For example, a single antenna element may include a first sub-element cross-polarized with a second sub-element that can be used to independently transmit cross-polarized signals. Antenna elements may include patch antennas, dipole antennas, and / or other types of antennas arranged in a linear pattern, a two-dimensional pattern, or another pattern. The spacing between antenna elements can allow signals with desired wavelengths transmitted individually by the antenna elements to interact or interfere (e.g., to form desired beams) in various directions. For example, given a desired wavelength or frequency range, the spacing may provide a quarter wavelength, half a wavelength, or another fraction of the wavelength of the spacing between adjacent antenna elements to allow desired constructive and destructive interference patterns of signals transmitted by individual antenna elements within that desired range. The amplitude and / or phase of signals transmitted via antenna elements and / or sub-elements may be modulated and (e.g., by manipulating phase shifts, phase offsets, and / or amplitudes) shifted relative to each other to generate one or more beams, a process known as beamforming. The term "beam" can refer to the directional transmission of a wireless signal toward a receiving device or otherwise in a desired direction. "Beam" can also typically refer to the direction associated with such directional signal transmission, the set of directional resources associated with the signal transmission (e.g., angle of arrival, horizontal direction and / or vertical direction), and / or a set of parameters indicating one or more aspects of the directional signal, the direction associated with the signal, and / or the set of directional resources associated with the signal.

[0093] Figure 3 This is a diagram illustrating example 300 associated with backscatter communication.

[0094] Some wireless communication devices can be considered IoT devices, such as environmental IoT devices (sometimes called ultralight IoT devices) or similar IoT devices. In environmental IoT, the terminal (e.g., RFID device, tag, or similar device) may not include a battery, and the terminal can accumulate energy from radio signaling. To achieve further cost reduction and zero-power communication, wireless networks can utilize a type of environmental IoT device known as an "environmental backscattering device" or "backscattering device".

[0095] like Figure 3 As shown, a backscattering device 305 (e.g., a tag or sensor, etc.), which may be an example of an environmental IoT device, can employ a simplified hardware design (e.g., including a power divider, energy harvester, and microcontroller). This hardware design does not include a battery, allowing the backscattering device 305 to rely on energy harvesting for power, and does not include radio wave generation circuitry, enabling the backscattering device 305 to transmit information solely by reflecting radio waves. More specifically, the backscattering device 305 communicates with a reader 308 (e.g., UE 120, network node 110, or another network device) by modulating reflected radio signals from an RF source 310 (e.g., network node 110, UE 120, or another network device). In some examples, the RF source 310 and the reader 308 may be the same device and / or may be co-located. For example, in some instances, the reader 308 and the RF source 310 may be associated with the same network node 110.

[0096] To facilitate communication with backscattering device 305, RF source 310 may send an energy harvesting wave to backscattering device 305. The energy harvesting wave may be sent for a sufficient duration to achieve a target range communication phase between reader 308 and backscattering device 305. Additionally or alternatively, in some instances, the range between RF source 310 and backscattering device 305 may be limited by a minimum received power, such as -20 dBm, to trigger energy harvesting at backscattering device 305.

[0097] Once sufficient energy has accumulated at backscattering device 305, backscattering device 305 can begin reflecting radio waves radiated to it via backscattering link 315. For example, RF source 310 can initiate a communication session with a query (sometimes referred to as query-response communication), where the query can be a modulated envelope of a carrier wave (CW). Backscattering device 305 can respond by backscattering the CW. The communication session can include multiple rounds, such as for contention resolution purposes when multiple backscattering devices respond to a query. The channel between RF source 310 and backscattering device 305 on backscattering link 315 can be compared with a first backscattering link channel response value (sometimes referred to as a first backscattering link channel coefficient or first backscattering link gain value), h BD Related to this, as described below, the backscattering device 305 may have a reflection on-time and reflection off-time that follow at least in part based on the pattern of information bit transmission by the backscattering device 305. The reader 308 may detect the reflection pattern of the backscattering device 305 and obtain backscattering communication information via the backscattering link 315. The channel between the reader 308 and the backscattering device 305 of the backscattering link 315 may be correlated with a second backscattering link channel response value (sometimes referred to as the second backscattering link channel coefficient or the second backscattering link channel gain value) h. DU Relatedly, RF source 310 and reader 308 can be communicated via direct link 320 (e.g., reference signals and / or data signals). The channel between RF source 310 and reader 308 of direct link 320 can be correlated with the direct link channel response value (sometimes referred to as the direct link channel coefficient or direct link channel gain value). BU Related.

[0098] The backscattering device 305 can use information modulation schemes such as amplitude shift keying (ASK) modulation or on-off keying (OOK) modulation. For ASK or OOK modulation, the backscattering device 305 can enable reflection when transmitting an information bit "1" and disable reflection when transmitting an information bit "0". In backscatter communication, the RF source 310 can transmit a specific radio wave (e.g., a reference signal or data signal, such as a physical downlink shared channel (PDSCH)), which can be represented as x(n). The reader 308 can receive the radio wave x(n) directly from the RF source 310 via a direct link 320, and receive the radio wave from the backscattering device 305, which modulates the radio wave and reflects it to the reader 308, via a backscattering link 315. The signal received at the reader 308 via the direct link 320 (indicated by reference numeral 325) is the radio wave x(n) transmitted by the RF source 310 multiplied by the direct link channel response value h. BU The product of these factors plus any signal noise. The information bit signal of the backscattering device 305 can be represented as s(n), where s(n) {0,1}. Therefore, the signal received at reader 308 via backscatter link 315 (indicated by reference numeral 330) is the signal x(n) transmitted by RF source 310 multiplied by the first backscatter link channel response value h. BD Second backscatter link channel response value h DU The product of the information bit signal s(n) from the backscattering device 305 and the reflection coefficient associated with the backscattering device 305, plus any noise.

[0099] Therefore, the signal received at reader 308 is a superposition of the signal received via direct link 320 and the signal received via backscatter link 315, which can be represented as y(n). This signal y(n) is indicated by reference numeral 335. As shown, when s(n) = 0 (indicated by reference numeral 340 in the graph shown at reference numeral 330), backscattering device 305 can turn off reflection, and therefore reader 308 receives only the direct link 320 signal. When s(n) = 1 (indicated by reference numeral 345 in the graph shown at reference numeral 330), backscattering device 305 can turn on reflection, and therefore reader 308 receives the superposition of both the direct link 320 signal and the backscatter link 315 signal. In order to receive the information bits transmitted by backscattering device 305, reader 308 can first treat the backscatter link 315 signal as interference, at least in part based on the direct link channel response value h. BUx(n) is decoded using (n). Then, the reader 308 can detect the presence of the signal components. In some instances, the backscatter device 305 may not maintain the state from communication session to communication session except for the contents stored in the memory of the backscatter device 305, such as the electronic product code (EPC) or similar information associated with the backscatter device 305.

[0100] In some respects, the techniques and apparatus described herein for feedback information communication in environmental IoT devices can be compared with, for example, those used in relation to, [other applications]. Figure 3 The described application combines control information for backscatter communication.

[0101] Figure 4 These are examples 400 to 440 illustrating a topology for an environmental IoT device.

[0102] Example 400 relates to a first topology, which may be referred to as Topology 1. In Topology 1, the environmental IoT device 450 can communicate directly and bidirectionally with one or more network nodes 110. For example, the environmental IoT device 450 and one or more network nodes 110 can exchange environmental IoT data and / or signaling. In some examples, a first network node 110 can send communication to the environmental IoT device 450, and a second network node 110 can receive communication from the environmental IoT device 450.

[0103] Example 410 relates to a second topology, which may be referred to as Topology 2. In Topology 2, the environmental IoT device 450 can communicate bidirectionally with an intermediate node 460 located between the environmental IoT device 450 and the network node 110. The intermediate node 460 can be any suitable device capable of implementing environmental IoT, such as a relay device, IAB node, UE 120, or repeater, etc. The intermediate node 460 can transmit environmental IoT data and / or signaling between the network node 110 and the environmental IoT device 450.

[0104] Example 420 relates to a third topology, which may be referred to as Topology 3. In some examples, in Topology 3, the environmental IoT device 450 may send environmental IoT data and / or signaling to network node 110 and receive environmental IoT data and / or signaling from auxiliary node 470. In some examples, in Topology 3, the environmental IoT device 450 may receive environmental IoT data and / or signaling from network node 110 and send environmental IoT data and / or signaling to auxiliary node 470. The auxiliary node may be any suitable device capable of implementing environmental IoT, such as a relay, IAB node, UE 120, or repeater, etc.

[0105] Example 430 relates to a fourth topology, which may be referred to as Topology 4. In Topology 4, the environmental IoT device 450 can communicate bidirectionally with the UE 120. For example, the environmental IoT device 450 and the UE 120 can exchange environmental IoT data and / or signaling.

[0106] In some respects, the techniques and apparatus described herein for feedback information communication in environmental IoT devices are applicable to, for example, relative to Figure 4 The described one or more topologies for communication between environmental IoT devices.

[0107] Figures 5A to 5C This is a diagram illustrating an example of communication associated with feedback information, where the feedback information is transmitted independently of the UL / BL data associated with the physical UL / BL data channel.

[0108] In Example 500, such as Figure 5A As shown, the wireless communication device (WCD) 502 and the environmental IoT device 504 can communicate with each other. The wireless communication device 502 can be a network node 110 or a UE 120, etc. The environmental IoT device 504 can be an environmental IoT device 135, etc. For example, the environmental IoT device 504 can be an environmental IoT device of type device 1, device 2a, or device 2b. The wireless communication device 502 and the environmental IoT device 504 can be configured as described above relative to... Figure 4 The described topology 1, topology 2, topology 3 or topology 4 communicate.

[0109] In the first operation 506, the wireless communication device 502 sends one or more DL / FL communications to the environmental IoT device 504. For example, the wireless communication device 502 may send one or more physical DL / FL data channel communications in a physical DL / FL data channel for the environmental IoT device 504 to receive. In some aspects, the environmental IoT device 504 may be configured to generate and send feedback information associated with the one or more DL / FL communications, as described below.

[0110] In the second operation 508, the environmental IoT device 504 may generate feedback information associated with the one or more DL / FL communications to be transmitted by the environmental IoT device 504. In some aspects, the environmental IoT device 504 may be configured to transmit the feedback information generated by the environmental IoT device 504 independently of the UL / BL data associated with the physical UL / BL data channel.

[0111] In some respects, the environmental IoT device 504 can generate feedback information such that the feedback information includes only ACK information (in other words, the feedback information can be ACK-only). In such respects, the feedback information generated by the environmental IoT device 504 will not include NACK information.

[0112] In some respects, the environmental IoT device 504 can generate feedback information such that the feedback information includes only NACK information (in other words, the feedback information can be NACK-only). In such respects, the feedback information generated by the environmental IoT device 504 will not include ACK information.

[0113] In some respects, the environmental IoT device 504 may generate feedback information such that the feedback information includes ACK information, NACK information, or some combination thereof. In such respects, the feedback information generated by the environmental IoT device 504 may include ACK-only information, NACK-only information, or both ACK and NACK information.

[0114] In some respects, the environmental IoT device 504 can generate feedback information on a per TB basis per UL / BL transmission. That is, in some respects, the environmental IoT device 504 can generate feedback information per TB per UL / BL communication.

[0115] In some aspects, the feedback information transmitted per TB per UL / BL may include a payload-based indication. In some aspects, the payload-based indication included in the feedback information may be a unit indication. In some such aspects, for NACK only, instead of using a single bit to indicate NACK and the device identifier (ID) or group ID (collectively referred to as device / group ID), the single bit may only indicate the device / group ID. Similarly, for ACK only, instead of using a single bit to indicate ACK and the device / group ID, the single bit may only indicate the device / group ID. For ACK / NACK, a single bit and the device / group ID are used, where the single bit indicates whether the feedback information is ACK or NACK. Additionally or alternatively, the payload-based indication included in the feedback information may be a multi-bit indication. In some such aspects, one or more bits in the multi-bit indication may be used to indicate the type of error associated with the NACK information item. The indicated error type may include, for example, a power error (e.g., a decoding error due to low power) or a memory error (e.g., the memory pointed to by the reader is locked or absent, or the memory is insufficient to buffer and decode data, etc.). Figure 5B Example structure 514 illustrates an example structure for feedback information, which includes a unit-based or multi-bit-based indication of the feedback information as described above. As shown, the feedback information may include a preamble, a device / group ID, one or more feedback information bits (ACK / NACK bits), and a set of cyclic redundancy check (CRC) bits.

[0116] In some aspects, the feedback information transmitted per TB per UL / BL may include sequence-based indications. In some aspects, the sequence-based indications included in the feedback information may be sequence-only. In some such aspects, the sequence-based indications may use sequences specific to the environment IoT device 504. Figure 5B Example structure 516 illustrates an example structure for including feedback information with a sequence-based indication that uses a sequence specific to the environment IoT device 504. Alternatively, the sequence-based indication may use the result of overlay encoding the sequence using the device ID of the environment IoT device 504. Figure 5B Example structure 518 illustrates an example structure for feedback information including a sequence-based indication, which uses the result of overlay encoding the sequence using the device ID of the ambient IoT device 504. In some aspects, such as Figure 5B As illustrated, feedback information including sequence-based indications may include a preamble (e.g., which would be used for automatic gain control (AGC)).

[0117] In some respects, the environmental IoT device 504 can generate feedback information based on multiple TBs transmitted per UL / BL. That is, in some respects, the environmental IoT device 504 can generate feedback information for multiple TBs of communication per UL / BL.

[0118] In some aspects, transmitting multi-TB feedback information per UL / BL may include a single feedback information item associated with those multiple TBs. For example, the feedback information may include a single ACK / NACK for all TBs associated with the DL / FL communication. In such an example, if a decoding error exists for at least one TB, the ambient IoT device 504 may generate feedback information including NACK (when the ambient IoT device 504 is configured for NACK only or for ACK plus NACK). Conversely, if the ambient IoT device 504 is configured for ACK only, the ambient IoT device 504 may suppress the generation or transmission of feedback information associated with the DL / FL communication.

[0119] In some aspects, sending multi-TB feedback information per UL / BL may include multiple feedback messages, each of which corresponds to a specific TB within those multiple TBs. That is, in some aspects, the feedback information may independently include confirmation information for each TB.

[0120] In some aspects, sending multi-TB feedback information per UL / BL may indicate one or more TBs that were not successfully received or decoded. That is, in some aspects, the feedback may only indicate those TBs of DL / FL communication that were not successfully received or decoded by the ambient IoT device 504. Alternatively, in some aspects, sending multi-TB feedback information per UL / BL may indicate one or more TBs that were successfully received and decoded. That is, in some aspects, the feedback may only indicate those TBs of DL / FL communication that were successfully received and decoded by the ambient IoT device 504. In some such aspects, the feedback information may include a preamble indicating the number of TBs indicated in the feedback information (e.g., the number of TBs indicated as not successfully received or decoded, or the number of TBs indicated as successfully received and decoded). In some aspects, the maximum supported number of TBs indicated may be predefined. In some such aspects, the feedback information may include a bit field carrying a value indicating the number of TBs indicated in the feedback information.

[0121] In some respects, the feedback information may include a preamble and at least one of the following: an identifier associated with the environmental IoT device 504, a set of CRC bits, or the number of TBs associated with the feedback information.

[0122] Figure 5C Example structure 520 illustrates an example structure for sending feedback information per multi-TB. As shown in the figure, in example structure 520, the feedback information includes a preamble, a device / group ID associated with the environment IoT device 504, feedback information for each of the n (n>1) TBs, and a set of CRC bits.

[0123] Figure 5C Example structure 522 illustrates another example structure for sending feedback information per multi-TB. As shown in the figure, in example structure 522, the feedback information includes a preamble, feedback information for each of the n TBs, and a set of CRC bits overlaid by the device / group ID associated with the environment IoT device 504.

[0124] Figure 5C Example structure 524 illustrates another example structure for sending feedback information for each multi-TB. As shown in the figure, in example structure 524, the feedback information includes a preamble, a device / group ID associated with the environment IoT device 504, an indication of the number of TBs indicated by the feedback information (e.g., an indication of n), feedback information for each of the n TBs, and a set of CRC bits.

[0125] Figure 5CExample structure 526 illustrates another example structure for sending feedback information for each multi-TB transmission. As shown, in example structure 526, the feedback information includes a preamble, an indication of the number of TBs indicated by the feedback information (e.g., an indication of n), feedback information for each of the n TBs, and a set of CRC bits. In example structure 526, at least a portion of the feedback information and the set of CRC bits are overridden using a device / group ID associated with the environmental IoT device 504.

[0126] return Figure 5A In the third operation 510 and the fourth operation 512, respectively, the environmental IoT device 504 can send feedback information associated with the one or more DL / FL communications, and the wireless communication device 502 can receive the feedback information associated with the one or more DL / FL communications. In some aspects, such as Figure 5A As indicated, the environmental IoT device 504 transmits feedback information independently of the UL / BL data associated with the physical UL / BL data channel, and the wireless communication device 502 receives feedback information independently of the UL / BL data associated with the physical UL / BL data channel.

[0127] For example, environmental IoT device 504 may transmit feedback information in physical DL / FL control channel communication (e.g., a physical channel separate from the physical UL / BL data channel). As another example, environmental IoT device 504 may transmit feedback information in physical UL / BL data channel communication (e.g., physical UL / BL data channel communication that does not include any UL / BL data). As yet another example, environmental IoT device 504 may transmit feedback information in MAC-CE (e.g., MAC-CE that does not include any UL / BL data).

[0128] In this way, by implementing the sending and receiving of feedback information associated with one or more DL / FL communications, the described technology can be used to convey feedback information (e.g., ACK information, NACK information, or retransmission requests, etc.) to support reliable and efficient DL / FL communication for IoT devices in the environment.

[0129] Figures 6A to 6C An example is illustrated in connection with communication of feedback information, where the feedback information is multiplexed with UL / BL data associated with the physical UL / BL data channel.

[0130] In Example 600, such as Figure 6AAs shown, WCD 602 ​​and environmental IoT device 604 can communicate with each other. Wireless communication device 602 can be network node 110 or UE 120, etc. Environmental IoT device 604 can be environmental IoT device 135, etc. For example, environmental IoT device 604 can be an environmental IoT device of type device 1, device 2a, or device 2b. Wireless communication device 602 and environmental IoT device 604 can be configured as described above relative to... Figure 4 The described topology 1, topology 2, topology 3 or topology 4 communicate.

[0131] In the first operation 606, the wireless communication device 602 sends one or more DL / FL communications to the environmental IoT device 604. For example, the wireless communication device 602 may send one or more physical DL / FL data channel communications in a physical FL data channel for the environmental IoT device 604 to receive. In some aspects, the environmental IoT device 604 may be configured to generate and send feedback information associated with the one or more DL / FL communications, as described below.

[0132] In the second operation 608, the environmental IoT device 604 may generate feedback information associated with the one or more DL / FL communications to be sent by the environmental IoT device 604. In some aspects, the environmental IoT device 604 may be configured to multiplex the feedback information generated by the environmental IoT device 604 with UL / BL data associated with the physical UL / BL data channel.

[0133] In some aspects, the environmental IoT device 604 generates feedback information such that the feedback information is multiplexed with UL / BL data according to a predefined number of bits of feedback information permitted to be multiplexed with UL / BL data. That is, in some aspects, the number of bits of feedback information that can be multiplexed with UL / BL data may be predefined. In some such aspects, to distinguish whether the feedback information is multiplexed with UL / BL data, when the environmental IoT device 604 has no feedback information to send, the bits configured to carry the feedback information may each be set to a specific value (e.g., 1). Alternatively, to distinguish whether the feedback information is multiplexed with UL / BL data, the environmental IoT device 604 may generate feedback information including a preamble indicating whether the bits used for the feedback information are present in the communication carrying UL / BL data.

[0134] In some aspects, the environmental IoT device 604 generates feedback information such that the feedback information is multiplexed with UL / BL data based on the number of bits of feedback information permitted to be multiplexed with UL / BL data, wherein the indication of the number of bits is received in DL / FL communication. That is, in some aspects, DL / FL communication can be used to dynamically indicate the number of bits of feedback information that can be multiplexed with UL / BL data.

[0135] In some aspects, the environmental IoT device 604 generates feedback information such that the feedback information is multiplexed with UL / BL data, at least in part, based on the number of DL / FL communications that need to provide feedback information. Therefore, in some aspects, the number of bits available for feedback information can be implicitly indicated, at least in part, based on the number of DL / FL communications that need to be acknowledged. In some such aspects, the number of DL / FL communications that need to provide feedback information can be determined using a minimum time interval and a counter. The minimum time interval can define the minimum amount of time between a DL / FL communication and a UL / BL communication that needs to carry the feedback information associated with the DL / FL communication. In some aspects, the minimum time interval can be (pre)configured, predefined, or dynamically indicated. A counter can be used to indicate the number of scheduled DL / FL communications.

[0136] Figure 6B Example 614 illustrates the association of feedback information with UL / BL data multiplexing based at least in part on the number of DL / FL communications for which feedback information is to be provided. Figure 6B In the example shown, the amount of time between DL / FL communication 616 and UL / BL communication 618 is less than the minimum time interval. Therefore, as shown, feedback information associated with DL / FL communication 616 needs to be provided in a later UL / BL communication (i.e., UL / BL communication 626). The amount of time between DL / FL communication 620 and UL / BL communication 626, and the amount of time between DL / FL communication 622 and UL / BL communication 626, is greater than the minimum time interval. Therefore, feedback information associated with DL / FL communication 620 and DL / FL communication 622 can be provided in UL / BL communication 626. Furthermore, the amount of time between DL / FL communication 624 and UL / BL communication 626 is less than the minimum time interval. Therefore, feedback information associated with DL / FL communication 624 needs to be provided in a later UL / BL communication (not shown). In this example, UL / BL communication 626 includes feedback information for three DL / FL communications (i.e., DL / FL communication 616, DL / FL communication 620, and DL / FL communication 622). In this example, the number of bits for feedback information in UL / BL communication 626 can be implicitly indicated, at least in part, based on the number (three) of DL / FL communications that need to be acknowledged in UL / BL communication 626.

[0137] In some aspects, feedback information may include an indication of the number of bits used for feedback information. In some aspects, communication including feedback information may include an identifier associated with the environmental IoT device 604, feedback information generated by the environmental IoT device 604, one or more sets of CRC bits, or UL / BL data.

[0138] Figure 6C Example structure 628 illustrates an example structure for communication including feedback information multiplexed with UL / BL data. As shown, in example structure 628, communication may include an ID associated with environmental IoT device 604, feedback information (ACK / NACK), a set of CRC bits associated with the identifier and feedback information, UL / BL data, and a set of CRC bits associated with the UL / BL data.

[0139] Figure 6C Example structure 630 illustrates another example structure for communication that includes feedback information multiplexed with UL / BL data. As shown, in example structure 630, communication may include an ID associated with environmental IoT device 604, feedback information (ACK / NACK), UL / BL data, and a set of CRC bits associated with the identifier, feedback information, and UL / BL data.

[0140] return Figure 6A In the third operation 610 and the fourth operation 612, respectively, the environmental IoT device 604 can send feedback information associated with the one or more DL / FL communications, and the wireless communication device 602 can receive feedback information associated with the one or more DL / FL communications. In some aspects, such as Figure 6A As indicated herein, the feedback information associated with the one or more DL / FL communications is multiplexed with the UL / BL data associated with the physical UL / BL data channel in the manner described above.

[0141] In some aspects, the chip duration used to transmit feedback information may be matched with the chip duration associated with transmitting UL / BL data. That is, in some aspects, the chip duration used for feedback information may be the same as the chip duration used for data transmission. Alternatively, the chip duration used to transmit feedback information may be different from the chip duration associated with transmitting UL / BL data. In some such aspects, the chip duration associated with transmitting feedback information may be calculated at least in part based on the chip duration associated with transmitting UL / BL data (e.g., the chip duration associated with transmitting feedback information may be X / 1 / X of the chip duration associated with transmitting UL / BL data). Alternatively, the chip duration associated with transmitting feedback information or the chip duration associated with transmitting UL / BL data may be (e.g., by wireless communication device 602) (dynamically).

[0142] In this way, by implementing the sending and receiving of feedback information associated with one or more DL / FL communications, the described technology can be used to convey feedback information (e.g., ACK information, NACK information, or retransmission requests, etc.) to support reliable and efficient DL / FL communication for IoT devices in the environment.

[0143] It is worth noting that the techniques and apparatus described herein can be used to transmit feedback information associated with UL or BL communication. For example, wireless communication devices 502 / 602 can use bitmaps to provide multi-TB feedback information, or a single bit can be used for multi-TB feedback information, as described above.

[0144] Figure 7 This is a flowchart of an example process 700 performed at an environmental IoT device or an apparatus that supports environmental IoT device feedback communication. Example process 700 is an example in which the apparatus or environmental IoT device (e.g., environmental IoT device 135 or environmental IoT device 504) performs operations associated with environmental IoT device feedback communication.

[0145] like Figure 7 As shown, in some aspects, process 700 may include: generating feedback information to be sent by an environmental IoT device, wherein the feedback information is associated with one or more DL / FL communications (box 710). For example, an environmental IoT device (such as by using...) Figure 12 The depicted communication manager 138 or feedback component 1208 can generate feedback information to be sent by the environmental IoT device, wherein the feedback information is associated with one or more DL / FL communications, as described above.
