Cross-reference to related applications

[0001] This patent application claims priority to U.S. Patent Application No. 18 / 469,663, filed September 19, 2023, entitled “FREQUENCY DIVERSITY FORHELPER TONE-BASED TRANSMISSION”, assigned to the assignee of this application. The disclosure of the earlier application is considered part of this patent application and is incorporated herein by reference. Technical Field

[0002] All aspects of this disclosure relate to wireless communication and to techniques and apparatus for frequency diversity for auxiliary tone-based transmission. Background Technology

[0003] Wireless communication systems are widely deployed to provide a variety of telecommunications services, such as telephone, video, data, messaging, and broadcasting. Typical wireless communication systems employ multiple access technologies that enable communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access technologies include Code Division Multiple Access (CDMA) systems, Time Division Multiple Access (TDMA) systems, Frequency Division Multiple Access (FDMA) systems, Orthogonal Frequency Division Multiple Access (OFDMA) systems, Single Carrier Frequency Division Multiple Access (SC-FDMA) systems, Time Division Synchronous Code Division Multiple Access (TD-SCDMA) systems, and Long Term Evolution (LTE). LTE / LTE-Advanced is a collection of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard issued by the 3rd Generation Partnership Project (3GPP).

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

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

[0029] Figure 12 This is a diagram of an example device for wireless communication according to the present disclosure. Detailed Implementation

[0030] In some examples, envelope tracking can be used by user equipment (UE) (e.g., network entities, lower-level devices, and / or tag devices) to decode radio signals. For example, envelope tracking can be used as a technique to detect and extract information from modulated signals. Envelope tracking can be used by the UE as a form of signal demodulation, which can recover baseband signals from modulated radio frequency (RF) signals. For example, the UE can receive signals with a received voltage that varies over time, and the amplitude of the signal can differ over time.

[0031] The UE may provide a signal (or information associated with the signal) to an envelope detector. The envelope detector may be configured to detect the envelope associated with the signal. As used herein, the “envelope” of a signal may refer to the amplitude or magnitude of the signal, since the amplitude or magnitude varies over time. The envelope may be a function of modulation applied to the signal. The envelope may be associated with an envelope voltage that indicates the voltage of the envelope over time. The UE may determine information about the signal (e.g., bit values) based on the envelope voltage, according to the envelope voltage, or otherwise associated with the envelope voltage (referred to herein as “at least partially based on the envelope voltage”). For example, the UE may be configured to determine, at least partially based on the envelope voltage at a given time, whether the voltage of the signal at a given time will be associated with “1” or “0” (e.g., for information bits of the signal). For example, the UE may compare the voltage of the envelope to one or more thresholds. As an example, if the value of the voltage at a given time meets a threshold, the UE may determine that the bit corresponding to the given time is associated with “1”. If the value of the voltage at a given time does not meet a threshold, the UE may determine that the bit corresponding to the given time is associated with “0”.

[0032] Therefore, the decoding operation performed by the UE can be simplified and / or associated with reduced complexity. For example, the UE can obtain the value of the information bits of the signal without using one or more active RF components. Additionally, the UE can obtain the value of the information bits of the signal without down-converting the signal to a baseband signal. As another example, envelope tracking decoding operation allows the UE to obtain the value of the information bits of the signal without performing carrier frequency offset and / or frequency synchronization. Therefore, less complex circuitry or components (or fewer components) can be included in the UE, and the UE can still decode the modulated signal by using envelope tracking.

[0033] However, in some examples, more than one transmitter (e.g., a network node or an attached UE) may transmit signals toward the UE in a spatial direction at a given time. For example, a first transmitter may transmit a first signal intended for use by the UE. A second transmitter may transmit a second signal toward the UE in a spatial direction, such that the UE receives, in addition to the first signal, a second signal that may not be intended for reception by the UE. In this way, the second signal may interfere with the first signal, which can cause the amplitude of the signal received at the UE to differ from the amplitude of the first signal. Therefore, the second signal may affect or modify the envelope of the first signal, causing the UE to be unable to accurately decode the first signal using the envelope tracking decoding operation described herein. For example, the received signal may be the sum of data transmitted via the first and second signals. Therefore, the UE may be unable to use envelope tracking to extract or recover the individual signals (e.g., because the envelope includes items as the sum of data transmitted via the first and second signals). Therefore, the communication performance and / or decoding performance associated with the UE may be degraded because the UE may incorrectly use envelope tracking to decode a signal when it receives one or more other signals at a time that at least partially overlaps with the time when the signal was received by the UE.

[0034] In some networks, the UE and transmitter may use envelope tracking-based decoding. For example, the signal to be decoded via envelope tracking may include communications (e.g., data or control information) and auxiliary signals. As used herein, "auxiliary signal" may refer to signaling transmitted on a single tone (e.g., a subcarrier or other frequency domain resource). For example, an auxiliary signal may include an entity "1" signal that can be located by the UE and used as a reference in the frequency domain to identify the portion of the frequency domain to be used for receiving communications. The communications and auxiliary signals may be separated in the frequency domain by a frequency offset. The UE may improve the isolation of information associated with communications from interfering signals and / or noise by modifying the received signal (or the envelope of the received signal) at least in part based on the frequency offset. Based at least in part on isolated communications, the UE can use envelope tracking with improved accuracy to decode communications.

[0035] In some networks, channel effects (e.g., fading) can negatively impact the performance of received signals. In some networks, frequency hopping or pilot signals (e.g., phase tracking reference signals (PT-RS)) can be used to avoid or correct these channel effects. However, decoding based on auxiliary signals may not be suitable for frequency hopping, and the UE may not be able to use pilot signals to correct channel effects, at least in part, based on factors such as whether the UE is low-power, RedCap, or a low-level device (such as a tag). In such cases, channel fading can lead to an increased error rate, which may consume network, processing, power, and / or communication resources to detect and / or correct errors via, for example, retransmission of communications, until the interference is low enough for the UE to identify the information in the communication.

[0036] The various aspects generally relate to wireless communication, and more specifically to decoding wireless communication signals via envelope tracking. Some aspects more specifically involve decoding based on auxiliary signals via envelope tracking of communication that includes data signals at multiple different frequencies.

[0037] In some aspects, communication may include a single auxiliary tone (e.g., on a single subcarrier or other frequency domain resource) and data signals on at least two frequency domain resources offset from that single auxiliary tone. For example, the data signals may include a first data signal offset from the auxiliary tone in a negative direction (e.g., lower than the auxiliary tone) and a second data signal offset from the auxiliary tone in a positive direction (e.g., higher than the auxiliary tone). The second data signal may be a repetition of the first data signal, such that the UE can receive the data signals with improved accuracy based at least in part on the frequency diversity of the repetition.

[0038] In some aspects, communication may include auxiliary tones (e.g., a first auxiliary tone and a second auxiliary tone) on two frequency resources spaced apart from each other in the frequency domain. In some aspects, communication may include a first data signal offset from a first frequency resource of the auxiliary tone (e.g., offset from a first auxiliary tone) by a first frequency offset and a second data signal offset from a second frequency resource of the auxiliary tone (e.g., offset from a second auxiliary tone) by a second frequency offset. In some aspects, the second data signal may be a repetition of the first data signal (e.g., carrying the same payload). In some aspects, the second data signal may carry a different payload than the first data signal. In some aspects, the first frequency offset and the second frequency offset may be the same offset (e.g., distance in the frequency domain) or may be different offsets.

[0039] 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 aspects, by transmitting data signals at different frequencies simultaneously using an auxiliary tone, the described techniques can be used to enable the UE to decode communications with improved accuracy using envelope tracking. For example, by using an auxiliary signal, the UE can decode communications with improved accuracy, at least in part, based on improved isolation of the associated data signals, and by using data signals at different frequencies, the UE can benefit from frequency diversity to reduce channel fading effects and other negative channel effects. In this way, the UE can receive communications with a reduced error rate, which saves network, processing, power, and / or communication resources that might otherwise have been consumed, for example, by retransmission of communications for error detection and / or correction until interference is low enough for the UE to identify the information in the communication.

[0040] Various aspects of this disclosure are described more fully below with reference to the accompanying drawings. However, this disclosure may be embodied in many different forms and should not be construed as limited to any particular structure or function presented throughout this disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of this disclosure to those skilled in the art. Those skilled in the art will appreciate that the scope of this disclosure is intended to cover any aspect of this disclosure disclosed herein, whether implemented independently or in combination with any other aspect of this disclosure. For example, any number of aspects set forth herein may be used to implement an apparatus or practice. Furthermore, the scope of this disclosure is intended to cover such apparatuses or methods practiced using structures, functionalities, or structures and functionalities other than or different from the various aspects of the disclosure set forth herein. It should be understood that any aspect of the disclosure herein may be embodied by one or more elements of the present claims.

[0041] Various devices and techniques will now be used to illustrate several aspects of a telecommunications system. These devices and techniques will be described in detail below and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, or algorithms (collectively, “elements”). These elements can be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the system as a whole.

[0042] Although terms generally associated with 5G or New Radio (NR) Radio Access Technology (RAT) may be used herein to describe aspects, aspects of this disclosure may be applied to other RATs, such as 3G RAT, 4G RAT and / or 5G and later (e.g., 6G) RATs.

[0043] Figure 1This is a diagram illustrating an example of a wireless network 100 according to the present disclosure. The wireless network 100 may be a 5G (e.g., NR) network and / or a 4G (e.g., LTE) network, or may include elements of a 5G (e.g., NR) network and / or elements of a 4G (e.g., LTE) network, etc. The wireless network 100 may include one or more network nodes 110 (shown as network node 110a, network node 110b, network node 110c, and network node 110d), one or more UEs 120 (shown as UE 120a, UE 120b, UE 120c, UE 120d, and UE 120e), and / or other entities. Network node 110 is a network node that communicates with UE 120. As shown, network node 110 may include one or more network nodes. For example, network node 110 can be an aggregated network node, meaning that an aggregated network node is configured to utilize a radio protocol stack that is physically or logically integrated within a single radio access network (RAN) node (e.g., within a single device or unit). As another example, network node 110 can be a decomposed network node (sometimes referred to as a decomposed base station), meaning that network node 110 is configured to utilize a protocol stack that is physically or logically distributed among two or more nodes (such as one or more central units (CUs), one or more distributed units (DUs), or one or more radio units (RUs)).

[0044] In some examples, network node 110 is or includes network nodes (such as RUs) that communicate with UE 120 via a radio access link. In some examples, network node 110 is or includes network nodes (such as DUs) that communicate with other network nodes 110 via a fronthaul or midhaul link. In some examples, network node 110 is or includes network nodes (such as CUs) that communicate with other network nodes 110 via a midhaul link or with the core network via a backhaul link. In some examples, network node 110 (such as aggregated network node 110 or decomposed network node 110) may include multiple network nodes, such as one or more RUs, one or more CUs, and / or one or more DUs. Network node 110 may include, for example, NR base stations, LTE base stations, Node Bs, eNBs (e.g., in 4G), gNBs (e.g., in 5G), access points, Transmit / Receive Points (TRPs), DUs, RUs, CUs, network mobility elements, core network nodes, network elements, network equipment, RAN nodes, or combinations thereof. In some examples, network nodes 110 can interconnect with each other or with one or more other network nodes 110 in the wireless network 100 using any suitable transport network through various types of fronthaul interfaces, midhaul interfaces, and / or backhaul interfaces (such as direct physical connections, air interfaces, or virtual networks).

[0045] In some examples, network node 110 may provide communication coverage for a specific geographic area. In the 3rd Generation Partnership Project (3GPP), depending on the context in which the term is used, the term "cell" may refer to the coverage area of ​​network node 110 and / or the network node subsystem serving that coverage area. Network node 110 may provide communication coverage for macrocells, picocells, femtocells, and / or another type of cell. A macrocell may cover a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access by UE 120 with a service subscription. A picocell may cover a relatively small geographic area and may allow unrestricted access by UE 120 with a service subscription. A femtocell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by UE 120 associated with the femtocell (e.g., UE 120 in a Closed Subscriber Group (CSG)). Network node 110 used for macrocells may be referred to as a macro network node. Network node 110 used for picocells may be referred to as a pico network node. The network node 110 used for femtocells can be referred to as a femtocell network node or a home network node. Figure 1 In the example shown, network node 110a can be a macro network node for macro cell 102a, network node 110b can be a pico network node for pico cell 102b, and network node 110c can be a femto network node for femto cell 102c. Network nodes can support one or more (e.g., three) cells. In some examples, cells may not necessarily be stationary, and the geographical area of ​​the cell may move depending on the location of a mobile network node 110 (e.g., a mobile network node).

[0046] In some aspects, the term "base station" or "network node" may refer to an aggregated base station, a decomposed base station, an integrated access and backhaul (IAB) node, a relay node, or one or more components thereof. For example, in some aspects, "base station" or "network node" may refer to a CU, DU, RU, a near real-time (near RT) RAN intelligent controller (RIC), or a non-real-time (non-RT) RIC, or a combination thereof. In some aspects, the term "base station" or "network node" may refer to a device configured to perform one or more functions (such as those described herein in conjunction with network node 110). In some aspects, the term "base station" or "network node" may refer to multiple devices configured to perform one or more functions. For example, in some distributed systems, each of multiple different devices (which may be located in the same geographical location or different geographical locations) may be configured to perform at least a portion of a function, or to repeatedly perform at least a portion of that function, and the term "base station" or "network node" may refer to any one or more of these different devices. In some aspects, the term "base station" or "network node" may refer to one or more virtual base stations or one or more virtual base station functions. For example, in some aspects, two or more base station functions can be instantiated on a single device. In some aspects, the term "base station" or "network node" may refer to one base station function rather than another. In this way, a single device may include more than one base station.

[0047] Wireless network 100 may include one or more relay stations. A relay station is a network node that can receive data transmissions from upstream nodes (e.g., network node 110 or UE 120) and transmit data to downstream nodes (e.g., UE 120 or network node 110). A relay station may be a UE 120 that can relay transmissions for other UE 120s. Figure 1 In the example shown, network node 110d (e.g., a relay network node) can communicate with network node 110a (e.g., a macro network node) and UE 120d to facilitate communication between network node 110a and UE 120d. The network node 110 for relay communication may be referred to as a relay station, relay base station, relay network node, relay node, relay, etc.

[0048] The wireless network 100 can be a heterogeneous network, comprising different types of network nodes 110, such as macro network nodes, pico network nodes, femto network nodes, relay network nodes, etc. These different types of network nodes 110 may have different transmit power levels, different coverage areas, and / or different effects on interference in the wireless network 100. For example, macro network nodes may have high transmit power levels (e.g., 5 watts to 40 watts), while pico network nodes, femto network nodes, and relay network nodes may have lower transmit power levels (e.g., 0.1 watts to 2 watts).

[0049] Network controller 130 may be coupled to or communicate with network node set 110, and may provide coordination and control for these network nodes 110. Network controller 130 may communicate with network nodes 110 via a backhaul or midhaul link. Network nodes 110 may also communicate directly with each other, or indirectly via a wireless or wired backhaul link. In some aspects, network controller 130 may be a CU or core network device, or may include a CU or core network device.

[0050] UE 120 may be distributed throughout the wireless network 100, and each UE 120 may be stationary or mobile. UE 120 may include, for example, access terminals, terminals, mobile stations, and / or subscriber units. UE 120 may be a cellular phone (e.g., a smartphone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet computer, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device, a biometric device, a wearable device (e.g., a smartwatch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring or smart bracelet)), an entertainment device (e.g., a music device, a video device, and / or a satellite radio), a vehicle component or sensor, a smart meter / sensor, industrial manufacturing equipment, a GPS device, a UE function of a network node, and / or any other suitable device configured to communicate via wireless or wired media.

[0051] Some UEs 120 may be considered machine-type communication (MTC) or evolved or enhanced machine-type communication (eMTC) UEs. MTC UEs and / or eMTC UEs may include, for example, robots, unmanned aerial vehicles, remote devices, sensors, instruments, monitors, and / or location tags that can communicate with network nodes, another device (e.g., a remote device), or some other entity. Some UEs 120 may be considered Internet of Things (IoT) devices and / or may be implemented as NB-IoT (Narrowband IoT) devices. Some UEs 120 may be considered customer premises equipment. UEs 120 may be included within a housing that houses the components of the UE 120, such as processor components and / or memory components. In some examples, the processor components and memory components may be coupled together. For example, the processor components (e.g., one or more processors) and memory components (e.g., memory) may be operatively coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0052] Generally, any number of wireless networks 100 can be deployed in a given geographical area. Each wireless network 100 can support a specific RAT and can operate on one or more frequencies. A RAT may be referred to as a radio technology, air interface, etc. A frequency may be referred to as a carrier, frequency channel, etc. Each frequency in a given geographical area can support a single RAT to avoid interference between wireless networks using different RATs. In some cases, NR or 5G RAT networks can be deployed.

[0053] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more sidelink channels (e.g., without using network node 110 as an intermediary device to communicate with each other). For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, or vehicle-to-pedestrian (V2P) protocols) and / or mesh networks. In such examples, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by network node 110.

[0054] Devices in Wireless Network 100 can communicate using the electromagnetic spectrum, which can be subdivided into various categories, bands, channels, etc., based on frequency or wavelength. For example, devices in Wireless Network 100 can communicate using one or more operating frequency bands. In 5G NR, two initial operating frequency bands have been designated as frequency ranges FR1 (410MHz to 7.125GHz) and FR2 (24.25GHz to 52.6GHz). It should be understood that although a portion of FR1 is greater than 6GHz, FR1 is often (interchangeably) referred to as the “sub-6GHz” band in various documents and articles. Similar naming issues sometimes occur with FR2, which is often (interchangeably) referred to as the “millimeter wave” band in documents and articles, although this is different from the Extremely High Frequency (EHF) band (30GHz to 300GHz) designated as a “millimeter wave” band by the International Telecommunication Union (ITU).

[0055] The frequencies between FR1 and FR2 are generally referred to as mid-band frequencies. Recent 5G NR studies have identified the operating bands used for these mid-band frequencies as the frequency range designation FR3 (7.125 GHz to 24.25 GHz). Bands falling within FR3 can inherit FR1 and / or FR2 characteristics, thus effectively extending the features of FR1 and / or FR2 to mid-band frequencies. Furthermore, higher frequency bands are currently being explored to extend 5G NR operation beyond 52.6 GHz. For example, three higher operating bands have been identified as the frequency range designations FR4a or FR4-1 (52.6 GHz to 71 GHz), FR4 (52.6 GHz to 114.25 GHz), and FR5 (114.25 GHz to 300 GHz). Each of these higher frequency bands falls within the EHF band.

[0056] Considering the examples above, unless otherwise specifically stated, it should be understood that when the term "below 6 GHz" is used herein, it can broadly refer to frequencies below 6 GHz, within FR1, or including intermediate frequency band frequencies. Furthermore, unless otherwise specifically stated, it should be understood that when the term "millimeter wave" is used herein, it can broadly refer to frequencies that can include intermediate frequency band frequencies, within FR2, FR4, FR4-a, or FR4-1 and / or FR5, or within the EHF band. Modifications to frequencies included in these operating frequency bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, and / or FR5) are contemplated, and the techniques described herein are applicable to those modified frequency ranges.

[0057] In some aspects, UE 120 may include a communication manager 140. As described in more detail elsewhere herein, the communication manager 140 may receive an indication of a frequency offset of an auxiliary tone associated with data communication, the auxiliary tone being associated with assisting the UE in filtering noise and / or interference from data signaling associated with the data communication; and receive the auxiliary tone and data communication, which includes data signals at different frequencies, these different frequencies being at least partially based on the frequency offset of the auxiliary tone. Additionally or alternatively, the communication manager 140 may perform one or more other operations described herein.

[0058] In some aspects, network node 110 may include communication manager 150. As described in more detail elsewhere herein, communication manager 150 may send an indication of a frequency offset of an auxiliary tone associated with data communication, the auxiliary tone being associated with assisting the UE in filtering noise and / or interference from data signaling associated with the data communication; and send the auxiliary tone and data communication, which includes data signals at different frequencies, these different frequencies being at least partially based on the frequency offset of the auxiliary tone. Additionally or alternatively, communication manager 150 may perform one or more other operations described herein.

[0059] As indicated above, Figure 1 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 1 The examples described are different.

[0060] Figure 2 This is a diagram illustrating example 200 of communication between network node 110 and UE 120 in a wireless network 100 according to this disclosure. Network node 110 may be equipped with a set of antennas 234a to 234t, such as... T One antenna ( T ≥1). UE 120 may be equipped with an array of antennas 252a to 252r, such as R One antenna ( R ≥1). Network node 110 of Example 200 includes one or more radio frequency components, such as antenna 234 and modem 232. In some examples, network node 110 may include an interface, communication components, or another component that facilitates communication with UE 120 or another network node. Some network node 110 may not include radio frequency components that facilitate direct communication with UE 120, such as one or more CUs or one or more DUs.

[0061] At network node 110, transmitting processor 220 may receive data from data source 212 intended for use by UE 120 (or a set of UEs 120). Transmitting processor 220 may select one or more modulation and decoding schemes (MCS) for UE 120 based at least in part on one or more channel quality indicators (CQIs) received from UE 120. Network node 110 may process (e.g., encode and modulate) the data for UE 120 based at least in part on the MCS selected for UE 120 and may provide data symbols for UE 120. Transmitting processor 220 may process system information (e.g., for semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper-layer signaling) and provide overhead symbols and control symbols. Transmitting 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 signal (PSS) or secondary synchronization signal (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 can perform spatial processing (e.g., pre-decoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols where applicable, and can process a set of output symbol streams (e.g., T The output symbol streams are provided to the corresponding set of modems 232 (e.g., 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19 ... T Each modem 232a to 232t can be used to process a corresponding output symbol stream (e.g., for OFDM) to obtain an output sample stream. For example, each output symbol stream can be provided to a modulator component (MOD) of modem 232. Each modem 232 can use a corresponding modulator component to process the corresponding output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modem 232 can also use a corresponding modulator component to process the output sample stream (e.g., convert to analog, amplify, filter, and / or up-convert) to obtain a downlink signal. Modems 232a to 232t can be used via a corresponding set of antennas 234 (e.g., T A collection of downlink signals (e.g., antennas 234a to 234t) is used to transmit downlink signals. T (One downlink signal).

[0062] At UE 120, the set of antennas 252 (shown as antennas 252a to 252r) can receive downlink signals from network node 110 and / or other network nodes 110 and can transmit the set of received signals (e.g., R The received signals) are provided to the set of modems 254 (e.g., REach modem 254 (shown as modems 254a to 254r) may receive a signal. For example, each received signal may be provided to a demodulator component (shown as DEMOD) of modem 254. Each modem 254 may use a corresponding demodulator component to condition (e.g., filter, amplify, down-convert, and / or digitize) the received signal to obtain an input sample. Each modem 254 may use a demodulator component to further process the input sample (e.g., for OFDM) to obtain a received symbol. MIMO detector 256 may obtain the received symbols from modem 254, perform MIMO detection on the received symbols where applicable, and provide the detected symbols. Receiver processor 258 may process (e.g., demodulate and decode) the detected symbols, provide the decoded data for UE 120 to data sink 260, and provide the decoded control information and system information to controller / processor 280. The term "controller / processor" may refer to one or more controllers, one or more processors, or a combination thereof. The channel processor can determine parameters such as Reference Signal Received Power (RSRP), Received Signal Strength Indicator (RSSI), Reference Signal Received Quality (RSRQ), and / or CQI. In some examples, one or more components of the UE 120 may be included in a housing.

[0063] Network controller 130 may include communication unit 294, controller / processor 290, and memory 292. Network controller 130 may include one or more devices, for example, in a core network. Network controller 130 may communicate with network node 110 via communication unit 294.

[0064] One or more antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include one or more antenna panels, one or more antenna groups, one or more collections of antenna elements, and / or one or more antenna arrays, etc., or may be included within one or more antenna panels, one or more antenna groups, one or more collections of antenna elements, and / or one or more antenna arrays, etc. Antenna panels, antenna groups, collections of antenna elements, and / or antenna arrays may include one or more antenna elements (within a single housing or multiple housings), collections of coplanar antenna elements, collections of non-coplanar antenna elements, and / or be coupled to one or more transmitting and / or receiving components (such as...). Figure 2 One or more antenna elements (one or more components in a )

[0065] On the uplink, at UE 120, the transmit processor 264 can receive and process data from data source 262 and control information from controller / processor 280 (e.g., for reporting including RSRP, RSSI, RSRQ, and / or CQI). The transmit processor 264 can generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 can be pre-decoded by the TX MIMO processor 266 where applicable, further processed by the modem 254 (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to network node 110. In some examples, the modem 254 of UE 120 may include a modulator and demodulator. In some examples, UE 120 includes a transceiver. The transceiver may include any combination of antenna 252, modem 254, MIMO detector 256, receive processor 258, transmit processor 264, and / or TX MIMO processor 266. The transceiver may be used by a processor (e.g., controller / processor 280) and memory 282 to execute this document (e.g., reference). Figures 7 to 12 ( ) describes aspects of any of the methods in the method.

[0066] At network node 110, uplink signals from UE 120 and / or other UEs may be received by antenna 234, processed by modem 232 (e.g., demodulator component of modem 232 (shown as DEMOD)), detected by MIMO detector 236, and further processed by receiver processor 238 to obtain decoded data and control information transmitted by UE 120. Receiver processor 238 may provide the decoded data to data sink 239 and the decoded control information to controller / processor 240. Network node 110 may include communication unit 244 and may communicate with network controller 130 via communication unit 244. Network node 110 may include scheduler 246 to schedule one or more UEs 120 for downlink and / or uplink communication. In some examples, modem 232 of network node 110 may include modulator and demodulator. In some examples, network node 110 includes transceiver. The transceiver may include any combination of antenna 234, modem 232, MIMO detector 236, receive processor 238, transmit processor 220, and / or TX MIMO processor 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to execute this document (e.g., reference). Figures 7 to 12 ( ) describes aspects of any of the methods in the method.

[0067] The controller / processor 240 of network node 110, the controller / processor 280 of UE 120 and / or Figure 2Any other component may perform one or more techniques associated with the auxiliary tone, as described in more detail elsewhere herein. For example, the controller / processor 240 of network node 110, the controller / processor 280 of UE 120, and / or Figure 2 Any other component that can execute or direct, for example Figure 9 The process 900 Figure 10 The operation of process 1000 and / or other processes as described herein. Memory 242 and memory 282 may store data and program code for network node 110 and UE 120, respectively. In some examples, memory 242 and / or memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, one or more instructions may cause one or more processors, UE 120 and / or network node 110 to perform or direct, for example, when executed by one or more processors of network node 110 and / or UE 120 (e.g., directly executed, or executed after compilation, transformation and / or interpretation). Figure 9 The process 900 Figure 10 The operation of process 1000 and / or other processes as described herein. In some examples, the execution instructions may include run instructions, transform instructions, compile instructions and / or interpret instructions, etc.

[0068] In some aspects, UE 120 includes components for receiving an indication of a frequency offset of an auxiliary tone associated with data communication, the auxiliary tone being associated with assisting UE 120 in filtering noise and / or interference from data signaling associated with the data communication; and / or components for receiving the auxiliary tone and data communication comprising data signals at different frequencies, these different frequencies being at least partially based on the frequency offset of the auxiliary tone. Components for enabling UE 120 to perform the operations described herein may include, for example, one or more of a communication manager 140, an antenna 252, a modem 254, a MIMO detector 256, a receive processor 258, a transmit processor 264, a TX MIMO processor 266, a controller / processor 280, or a memory 282.

[0069] In some aspects, network node 110 includes components for transmitting an indication of a frequency offset of an auxiliary tone associated with data communication, the auxiliary tone being associated with assisting the UE in filtering noise and / or interference from data signaling associated with the data communication; and / or components for transmitting the auxiliary tone and data communication, the data communication comprising data signals at different frequencies, these different frequencies being at least partially based on the frequency offset of the auxiliary tone. Components for enabling network node 110 to perform the operations described herein may include, for example, one or more of a communication manager 150, a transmit processor 220, a TX MIMO processor 230, a modem 232, an antenna 234, a MIMO detector 236, a receive processor 238, a controller / processor 240, a memory 242, or a scheduler 246.

[0070] In some respects, a single processor can be described as performing all functions executed by the one or more processors. In other respects, the one or more processors can collectively perform a set of functions. For example, a first set of processors(s) of the one or more processors can be described as performing a first function executed by the one or more processors, and a second set of processors(s) of the one or more processors can be described as performing a second function executed by the one or more processors. The first set of processors and the second set of processors can be the same set of processors or can be different sets of processors. The reference to "one or more processors" should be understood as referring to a combination of functions. Figure 2 The processor described refers to any 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, a function described as being performed by one or more memories can be performed by the same subset of the one or more memories or by different subsets of the one or more memories.

[0071] Although Figure 2 The boxes in the diagram are illustrated as different components, but the functions described above with respect to these boxes may be implemented in a single hardware, software, or combined component, or in various combinations of components. For example, the functions described with respect to transmit processor 264, receive processor 258, and / or TX MIMO processor 266 may be performed by or under the control of controller / processor 280.

[0072] As indicated above, Figure 2 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 2 The examples described are different.

[0073] The deployment of communication systems such as 5G NR systems can be arranged in a variety of ways using various components or constituent parts. In a 5G NR system or network, network nodes, network entities, network mobility elements, RAN nodes, core network nodes, network elements, base stations, or network equipment can be implemented in either a converged or decomposed architecture. For example, a base station (such as a Node B (NB), evolved NB (eNB), NR base station, 5G NB, access point (AP), TRP, or cell, etc.) or one or more units (or components) performing base station functionality can be implemented as a converged base station (also known as a standalone base station or monolithic base station) or a decomposed base station. A "network entity" or "network node" can refer to a decomposed base station or one or more units of a decomposed base station (such as one or more CUs, one or more DUs, one or more RUs, or combinations thereof).

[0074] Aggregated base stations (e.g., aggregated network nodes) can be configured to utilize a radio protocol stack that is physically or logically integrated within a single RAN node (e.g., within a single device or cell). Decomposed base stations (e.g., decomposed network nodes) can be configured to utilize a protocol stack that is physically or logically distributed across two or more cells (such as one or more CUs, one or more DUs, or one or more RUs). In some examples, the CU may be implemented within a network node, and one or more DUs may be co-located with the CU, or alternatively, may be geographically or virtually distributed across one or more other network nodes. DUs may be implemented to communicate with one or more RUs. Each of the CU, DU, and RU may also be implemented as a virtual cell, such as a Virtual Central Unit (VCU), a Virtual Distributed Unit (VDU), or a Virtual Radio Unit (VRU), etc.

[0075] Base station type operation or network design can take into account the aggregation characteristics of base station functionality. For example, decomposed base stations can be utilized in IAB networks, Open Radio Access Networks (O-RAN (such as network configurations initiated by the O-RAN Alliance)), or Virtualized Radio Access Networks (vRAN, also known as Cloud Radio Access Networks (C-RAN)) to facilitate the scaling of communication systems by separating base station functionality into one or more units that can be deployed independently. Decomposed base stations can include functionality implemented by two or more units across various physical locations, as well as functionality virtually implemented for at least one unit, which enables flexibility in network design. The various units of a decomposed base station can be configured for wired or wireless communication with at least one other unit of the decomposed base station.

[0076] Figure 3This is an illustration of an example disaggregated base station architecture 300 according to this disclosure. The disaggregated base station architecture 300 may include a CU 310, which may communicate directly with the core network 320 via a backhaul link, or indirectly with the core network 320 via one or more disaggregated control units (such as near-RT RIC 325 via an E2 link, or a non-RT RIC 315 associated with a Service Management and Orchestration (SMO) framework 305, or both). The CU 310 may communicate with one or more DUs 330 via a corresponding midhaul link (such as via an F1 interface). Each DU 330 may communicate with one or more RUs 340 via a corresponding fronthaul link. Each RU 340 may communicate with one or more UEs 120 via a corresponding radio frequency (RF) access link. In some implementations, a UE 120 may be served simultaneously by multiple RUs 340.

[0077] Each unit in the cells (including CU 310, DU 330, RU 340), as well as the near-RT RIC 325, non-RT RIC 315, and SMO frame 305, may include or be coupled to one or more interfaces configured to receive or transmit signals, data, or information (collectively, signals) via wired or wireless transmission media. Each unit in the cell, or an associated processor or controller providing instructions to one or more communication interfaces of the corresponding unit, may be configured to communicate with one or more units in other cells via transmission media. In some examples, each unit in the cell may include a wired interface and a wireless interface configured to receive signals via a wired transmission media or transmit signals to one or more units in other cells, and the wireless interface may include a receiver, transmitter, or transceiver (such as an RF transceiver) configured to receive signals via a wireless transmission media or transmit signals to one or more units in other cells, or both.

[0078] In some aspects, the CU 310 can host one or more higher-level control functions. Such control functions may include Radio Resource Control (RRC) functions, Packet Data Convergence Protocol (PDCP) functions, or Service Data Adaptation Protocol (SDAP) functions, etc. Each control function can be implemented using an interface configured to signal to other control functions hosted by the CU 310. The CU 310 can be configured to handle user plane functions (e.g., Central Unit-User Plane (CU-UP) functions), control plane functions (e.g., Central Unit-Control Plane (CU-CP) functions), or combinations thereof. In some implementations, the CU 310 can be logically split into one or more CU-UP units and one or more CU-CP units. When implemented in an O-RAN configuration, the CU-UP units can communicate bidirectionally with the CU-CP units via an interface such as an E1 interface. The CU 310 can be implemented to communicate with the DU 330 for network control and signaling purposes, as needed.

[0079] Each DU 330 may correspond to a logical unit comprising one or more base station functions for controlling the operation of one or more RU 340s. In some aspects, the DU 330 may, at least in part, host one or more of the Radio Link Control (RLC) layer, Medium Access Control (MAC) layer, and one or more high physical (PHY) layers, depending on functional splits (such as those defined by 3GPP). In some aspects, the one or more high PHY layers may be implemented by one or more modules for forward error correction (FEC) encoding and decoding, scrambling, and modulation and demodulation, etc. In some aspects, the DU 330 may also host one or more low PHY layers, such as those implemented by one or more modules for Fast Fourier Transform (FFT), Inverse FFT (iFFT), Digital Beamforming, or Physical Random Access Channel (PRACH) extraction and filtering, etc. Each layer (which may also be referred to as a module) may be implemented using an interface configured to communicate signals with other layers (and modules) hosted by the DU 330 or with control functions hosted by the CU 310.

[0080] Each RU 340 can implement lower-layer functionality. In some deployments, an RU 340 controlled by a DU 330 can correspond to a logical node that hosts RF processing functions or low-PHY layer functions, such as performing FFT, performing iFFT, digital beamforming, or PRACH extraction and filtering, based on function splitting (e.g., function splitting defined by 3GPP) (such as lower-layer function splitting). In such architectures, each RU 340 can be operated to handle over-the-air (OTA) communications with one or more UE 120s. In some specific implementations, the real-time and non-real-time aspects of control plane and user plane communications with the RU 340 can be controlled by the corresponding DU 330. In some scenarios, this configuration allows each DU 330 and CU 310 to be implemented in a cloud-based RAN architecture, such as a vRAN architecture.

[0081] The SMO framework 305 can be configured to support RAN deployment and provisioning of both non-virtualized and virtualized network elements. For non-virtualized network elements, the SMO framework 305 can be configured to support the deployment of dedicated physical resources for RAN coverage requirements, which can be managed via operation and maintenance interfaces such as the O1 interface. For virtualized network elements, the SMO framework 305 can be configured to interact with cloud computing platforms such as the Open Cloud (O-Cloud) platform 390 to perform network element lifecycle management (such as instantiating virtualized network elements) via cloud computing platform interfaces such as the O2 interface. Such virtualized network elements may include, but are not limited to, CU 310, DU 330, RU 340, non-RT RIC 315, and near-RT RIC 325. In some specific implementations, the SMO framework 305 can communicate with the hardware aspects of the 4G RAN (such as the Open eNB (O-eNB) 311) via the O1 interface. Additionally, in some implementations, the SMO framework 305 can communicate directly with each of one or more RUs 340 via a corresponding O1 interface. The SMO framework 305 may also include a non-RTRIC 315 configured to support the functionality of the SMO framework 305.

[0082] The non-RT RIC 315 can be configured to include logical functions that enable non-real-time control and optimization of RAN elements and resources, including artificial intelligence / machine learning (AI / ML) workflows for model training and updates, or policy-based guidance for applications / features in the near-RT RIC 325. The non-RT RIC 315 can be coupled to or communicate with the near-RT RIC 325, such as via an A1 interface. The near-RT RIC 325 can be configured to include logical functions that enable near real-time control and optimization of RAN elements and resources via an interface, such as an E2 interface, through data collection and actions, connecting one or more CU 310s, one or more DU 330s, or both, and O-eNBs to the near-RT RIC 325.

[0083] In some implementations, to generate AI / ML models to be deployed in the near-RT RIC 325, the non-RT RIC 315 may receive parameters or external enrichment information from an external server. This information can be utilized by the near-RT RIC 325 and can be received from non-network data sources or network functions at the SMO framework 305 or the non-RT RIC 315. In some examples, the non-RT RIC 315 or near-RT RIC 325 may be configured to tune RAN behavior or performance. For example, the non-RT RIC 315 may monitor long-term trends and patterns in performance and employ AI / ML models to perform corrective actions via the creation of the SMO framework 305 (such as reconfiguration via the O1 interface) or via RAN management policies (such as A1 interface policies).

[0084] As indicated above, Figure 3 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 3 The examples described are different.

[0085] Figure 4 This is a diagram illustrating example 400 associated with backscatter communication according to this disclosure.

[0086] Some network entities can be considered Internet of Things (IoT) devices, such as environmental IoT devices (sometimes referred to as ultralight IoT devices) or similar IoT devices. IoT technologies can include passive IoT (e.g., NR passive IoT for 5G advanced), semi-passive IoT, ultralight IoT, or environmental IoT, etc. In passive IoT, the terminal (e.g., a radio frequency identification (RFID) device, tag, or similar device) may not include a battery, and the terminal can accumulate energy from RF signaling. Additionally, the terminal can accumulate solar energy to supplement the accumulated energy from radio signaling. In passive IoT, the communication distance can be up to 30 meters (or longer) to facilitate feasible network coverage of large areas (e.g., 5000 square meters) such as in a warehouse. Furthermore, the power consumption of passive IoT terminals can be less than 0.1 milliwatts (mW) to support battery-free operation, and the terminals can be relatively inexpensive to facilitate cost-sensitive uses. The positioning accuracy of passive IoT terminals can be approximately 3 to 5 meters in both the horizontal and vertical directions.

[0087] Passive IoT combined with industrial sensors can be useful, for which battery replacement can be very difficult or undesirable (e.g., for security monitoring or fault detection in smart factories, infrastructure, or environments). Additionally, the characteristics of passive IoT devices, such as low cost, small size, maintenance-free operation, durability, and long lifespan, can facilitate smart logistics / warehousing (e.g., combined with automated asset management via RFID tag replacement). Furthermore, passive IoT can be combined with smart home networks for home appliance management, wearable devices (e.g., wearables for medical monitoring of patients that do not require battery replacement), and / or environmental monitoring. To achieve further cost reductions and zero-power communication, 5G and / or 6G wireless networks can utilize a type of passive IoT device known as an "ambient backscatter device" or "backscatter device."

[0088] Network entity 405 includes devices such as UEs, low-level devices (e.g., without active RF components), RedCap devices, tags (e.g., without active RF components), sensors, passive devices (such as passive IoT devices), semi-passive devices, low-power devices, and / or active devices, etc. Network entity 405 may be powered at least partially by receiving RF signals (e.g., from transmitter 410). In some examples, network entity 405 may be a UE, a low-level device, and / or a tag device. In some examples, network entity 405 may employ a simplified hardware design (e.g., including a power divider, energy harvester, and microcontroller) that does not include a battery and / or oscillator, allowing network entity 405 to be powered using energy harvesting, and that does not include radio wave generation circuitry, enabling network entity 405 to transmit information solely by reflecting radio waves. In some examples, network entity 405 may include a battery, capacitor, or another form of energy storage device. In some examples, network entity 405 may include a communication module, such as a Bluetooth Low Energy (BLE) module, a WiFi module, etc. The communication module may be at least partially powered by RF signals transmitted by transmitter 410, enabling network entity 405 to communicate with transmitter 410 or another device using a communication module powered by RF signals. In some examples, network entity 405 may include radio wave generation circuitry that may be powered by receiving RF signals and / or by energy storage in network entity 405. Transmitter 410 may be a network node or another UE.

[0089] In some examples, network entity 405 can communicate with reader 408 (e.g., which may include a UE, network node, base station, or other network device) by modulating reflected radio signals from transmitter 410 (referred to herein as a transmitter (e.g., a network node or another network device)). In some examples, transmitter 410 and reader 408 may be the same device and / or co-located. In some examples, transmitter may be referred to as exciter. In some examples, network entity 405 may not communicate with reader 408. For example, network entity 405 may communicate with another device (e.g., transmitter 410, RF energy harvesting device, or another network node). Reader 408 may be optional.

[0090] To facilitate communication with network entity 405, transmitter 410 may transmit an RF signal (e.g., an energy harvesting wave) to network entity 405. When facilitating communication with reader 408, the energy harvesting wave may be transmitted for a sufficient duration to achieve a communication phase within a target range between reader 408 and network entity 405. Additionally or alternatively, in some cases, the range between transmitter 410 and network entity 405 may be limited by a minimum received power (such as -20 dBm) required to trigger energy harvesting at network entity 405.

[0091] Once sufficient energy has been accumulated at network entity 405, network entity 405 can initiate communication or store energy. As an example, network entity 405 can reflect radio waves radiated onto itself via backscatter link 415. For instance, transmitter 410 can initiate a communication session with a query (sometimes referred to as query-response communication), which can be a modulated envelope of continuous wave (CW). Network entity 405 can respond via backscattering of 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 transmitter 410 and network entity 405 via backscatter link 415 can be correlated with a first backscatter link channel response value (sometimes referred to as a first backscatter link channel coefficient or a first backscatter link gain value). h BD Associated with, as described below, network entity 405 may have a reflection on-time and reflection off-time that follow at least in part based on the pattern of information bits transmitted by network entity 405. Reader 408 may detect the reflection pattern of network entity 405 and obtain backscatter communication information via backscatter link 415. The channel between reader 408 and network entity 405 of backscatter link 415 may be correlated with a second backscatter link channel response value (sometimes referred to as the second backscatter link channel coefficient or second backscatter link channel gain value). h DU Associated with each other. Furthermore, transmitter 410 and reader 408 may communicate (e.g., reference signals and / or data signals) via direct link 420. The channel between transmitter 410 and reader 408 on direct link 420 may be correlated with direct link channel response values ​​(sometimes referred to as direct link channel coefficients or direct link channel gain values). h BU Related. In some examples, network entity 405 may use the received energy to power active transmission (e.g., using an amplifier) ​​or other operations.

[0092] In some examples, transmitter 410 may include a power source (e.g., a portable power source, such as a battery or hardwired power supply). Transmitter 410 may include transmitting components, such as an RF chain including a power amplifier and one or more antennas. In some examples, the one or more antennas may be capable of some degree of beamforming (either based on a hardware configuration of the antenna array or via a dynamic beamforming method such as analog or digital beamforming) such that the RF signal transmitted by transmitter 410 is directed to a coverage area (e.g., an area such as a portion of a sphere, an azimuth angle, etc.) in which network entity 405 may be excited by the RF signal. In some examples, transmitter 410 may include one or more sensors, such as RF sensors, light sensors, motion sensors, etc. In some examples, transmitter 410 may be associated with (e.g., including, connected to, or communicating with) a BLE module, which is a module capable of transmitting and / or receiving BLE signaling (such as BLE communication). In some examples, the BLE module may include an RF sensor. As shown in the figure, transmitter 410 may include one or more processors that can perform the operations described herein, or are configured to perform the operations described herein.

[0093] If backscatter communication is performed, network entity 405 can use an information modulation scheme, such as amplitude shift keying (ASK) modulation, phase shift keying (PSK) modulation, or on / off keying (OOK) modulation. For the information modulation scheme, network entity 405 can enable reflection when transmitting an information bit "1" and disable reflection when transmitting an information bit "0". In backscatter communication, transmitter 410 can transmit specific radio waves (e.g., reference signals or data signals, such as the Physical Downlink Shared Channel (PDSCH)) (which can be represented as...). The reader 408 can receive the radio waves directly from the transmitter 410 via a direct link 420, and from the network entity 405 that modulates and reflects the radio waves to the reader 408 via a backscatter link 415. The signal received at reader 408 via direct link 420 (represented as...) (and indicated by reference numeral 425) are radio waves transmitted by transmitter 410. Multiply by the direct link channel response value h BU The product of the product and any signal noise. The information bit signal of network entity 405 can be represented as... ,in Therefore, the signal received at reader 408 via backscatter link 415 (denoted as...) (and indicated by reference numeral 430) is a signal transmitted by transmitter 410. Multiply by the first backscatter link channel response value h BD Second backscatter link channel response value h DU Information bit signal from network entity 405 and the reflection coefficient associated with network entity 405 The product plus any noise.

[0094] Therefore, if backscatter communication is performed, the signal received at reader 408 (which is the superposition of the signal received via direct link 420 and the signal received via backscatter link 415) can be represented as: ,in This signal As shown by reference numeral 435 in the figure. As illustrated, when (As indicated by reference numeral 440 in the graph shown at reference numeral 430), when network entity 405 can turn off reflection, the signal components... It equals zero, and therefore reader 408 only receives signals from direct link 420 (e.g., ).when (As indicated by reference numeral 445 in the graph shown at reference numeral 430) when network entity 405 can enable reflection, such that the signal components equal Therefore, reader 408 receives the superposition of the direct link 420 signal and the backscattered link 415 signal (e.g., In order to receive the information bits sent by network entity 405, reader 408 may first treat the backscattered link 415 signal as interference, at least in part based on the direct link channel response value. To decode Then, reader 408 can access the data from... minus To detect signal components The existence of [something]. In some cases, apart from the contents stored in the memory of network entity 405 (such as the electronic product code (EPC) or similar information associated with network entity 405), network entity 405 may not maintain the state from communication session to communication session.

[0095] Network entity 405 can detect or decode radio waves (e.g., reference signals or data signals, such as PDSCH) transmitted by transmitter 410. Network entity 405 can detect or decode radio waves via envelope tracker 450. Envelope tracker 450 can be a component or module of network entity 405 associated with decoding radio signals via envelope tracking. As used herein, the “envelope” of a signal can refer to the amplitude or magnitude of the signal, since the amplitude or magnitude varies over time. The envelope can be a function of modulation applied to the signal. The envelope can be represented as a waveform that captures the change in signal amplitude over time. When a modulation scheme is applied to the signal, the envelope of the signal varies according to the modulated waveform. Envelope tracking can be used as a technique for detecting and extracting modulated signals in a wireless communication system. For example, envelope tracking can be used by network entity 405 as a form of signal demodulation, which can recover the baseband signal from the modulated RF signal, as described in more detail elsewhere herein.

[0096] Some IoT devices can be termed semi-passive IoT devices, at least in part based on the fact that communication between the reader and the IoT device does not initially require an energy harvesting waveform. For example, a semi-passive IoT device may include a battery or similar energy source that can power the receiver and / or logic circuitry. For such devices, energy harvesting can still be triggered in some cases, such as for long-range communication. In such examples, the rectifier circuitry of the IoT device may have a hot-start capability from a battery or other energy source, and thus may be associated with a lower minimum receive power requirement than that of a passive IoT device (e.g., -30dBm instead of -20dBm). However, long-range communication may require battery power consumption to incentivize each decoding. More specifically, for long-range communication where the energy harvesting rate is lower than required by the decoding circuitry, such as when the energy harvesting rate is below -30dBm, a semi-passive IoT device may consume battery power to incentivize each decoding. Therefore, continuous IoT device monitoring (such as for receiving long-range query communications) can lead to excessive battery consumption at the IoT device.

[0097] In this respect, passive and semi-passive IoT devices can inherently limit their applications. For example, passive IoT devices can be associated with low cost and low form factor because no RF chain is required at the IoT device level. However, these devices require an energy harvesting waveform, thus limiting the application of such passive IoT devices to short-range communication. While semi-passive IoT devices can eliminate the need for an energy harvesting waveform and / or enable long-range communication, such devices increase cost and complexity because they require the use of batteries or similar power sources. Furthermore, because passive and semi-passive devices can be associated with communication sessions initiated by RF sources, these devices may inherently limit their use in sensing scenarios or similar latency-critical applications requiring non-periodic business, and these devices may not scale well for high IoT density applications.

[0098] In some cases, ambient IoT devices (sometimes called ultralight IoT devices) can be employed to overcome some of the limitations of passive and semi-passive IoT devices. Ambient IoT devices can be devices capable of transmitting uplink triggers and thus initiating communication sessions from the IoT device side. For example, an ambient IoT device may be associated with uplink transmissions that do not utilize a PA (e.g., transmissions in the 0dBm to 5dBm range), and for such uplink transmissions, there are limited transmission capabilities, such as the ability to simply send a preamble to indicate uplink traffic. Ambient IoT devices, passive devices, and semi-passive devices are referred to herein as RF energy harvesting devices (although RF energy harvesting devices may include another form of device capable of harvesting RF energy from RF signals to power the operation of the device).

[0099] As indicated above, Figure 4 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 4 The descriptions are different.

[0100] Figure 5 This is a diagram illustrating example 500 associated with envelope tracking according to this disclosure. (Combined) Figure 5 The described and depicted operations may be performed by network node 110 and / or UE 120, etc. In some examples, network entities may be tags (e.g., RFID tags), sensors, passive devices, passive IoT devices, semi-passive devices, active devices, RedCap devices, low-level devices, NR-Lite devices, and / or UEs, etc., associated with reduced RF capabilities. For example, network entities may not include active RF components such as oscillators, power amplifiers, low-noise amplifiers, mixers, and / or other RF components.

[0101] Envelope tracking can be used by network entities to decode wireless signals. For example, envelope tracking can be used as a technique for detecting and extracting modulated signals. Envelope tracking can also be used by network entities as a form of signal demodulation, which can recover the baseband signal from the modulated RF signal. For example, a network entity can receive a received voltage (V) with time. R The signal 505. For example, the amplitude of the signal may vary over time, such as... Figure 5 As shown.

[0102] A network entity may provide a signal (or information associated with the signal) to an envelope detector 510 (e.g., which may resemble an envelope tracker 450). The envelope detector 510 may be configured to detect the envelope 515 associated with the signal 505. In some examples, the envelope detector 510 may be configured to detect the upper envelope of the signal 505. The upper envelope may be a waveform indicating the upper limit of the amplitude of the signal 505 over time. For example, the envelope 515 of the signal 505 may be derived from... Figure 5The bold waveform shown is illustrated. Envelope 515 can be associated with an envelope voltage (V) indicating the voltage across envelope 515 over time. E (related to)

[0103] The network entity can provide the envelope 515 and / or envelope voltage (V) to the low-pass filter 520. E The low-pass filter 520 can be associated with a filtering frequency above a frequency threshold. For example, the low-pass filter 520 can allow signals with lower frequencies to pass through while blocking signals with higher frequencies (e.g., above a frequency threshold). The network entity can provide the low-pass filter 520 with an envelope 515 and / or an envelope voltage (V). E The baseband signal associated with signal 505 is extracted. Low-pass filter 520 removes high-frequency components of signal 505, leaving only the filtered signal 525 at the output of low-pass filter 520. Then, as described herein, the voltage (V) with time can be further processed. LP The filtered signal 525.

[0104] For example, a network entity can provide comparator 530 with a voltage (V) that varies with time. LP The filtered signal 525. Comparator 530 can be configured to determine the voltage (V) of a signal at a given time. O This is a component that will be associated with either "1" or "0" (e.g., for the information bits of signal 505). For example, comparator 530 can compare the voltage of filtered signal 525 to one or more thresholds. As an example, if the voltage value at a given time meets a threshold, comparator 530 can determine that filtered signal 525 is associated with "1" at that time. If the voltage value at a given time does not meet a threshold, comparator 530 can determine that filtered signal 525 is associated with "0" at that time. Comparator 530 can provide a voltage (V O The output 535 indicates a "1" or "0" for the corresponding information bit of signal 505.

[0105] like Figure 5As shown, a network entity can decode information bits (e.g., a series of "1"s and / or "0"s) based on the output of comparator 530. For example, for a time window (e.g., a given amount of time), the network entity can determine whether the comparator's output 535 indicates "0" or "1". The network entity can determine, based on the comparator 530's output 535, according to that output, or otherwise associated with that output (e.g., associated with a time window), whether a bit is associated with "0" or "1". Therefore, the decoding operation performed by the network entity can be simplified and / or associated with reduced complexity. For example, it enables the network entity to obtain the value of the information bits of signal 505 without using one or more active RF components. Additionally, it enables the network entity to obtain the value of the information bits of signal 505 without downconverting signal 505 to a baseband signal. As another example, envelope tracking decoding operations enable the network entity to obtain the value of the information bits of signal 505 without performing carrier frequency offset and / or frequency synchronization.

[0106] However, in some cases, more than one transmitter may send signals toward a network entity in a spatial direction at a given time. For example, a first transmitter may send a first signal (s1) toward a network node. The first signal may be a signal intended for use by the network node. Another transmitter may send a second signal (s2) toward the network node in a spatial direction, causing the network entity to receive the second signal. The second signal may or may not be intended for use by the network node. The first and second signals may at least partially overlap in the time domain. For example, the second signal may interfere with the first signal, causing the amplitude of the signal received at the network entity to differ from the amplitude of the first signal. Therefore, the second signal may affect or modify the envelope of the first signal, preventing the network entity from accurately decoding the first signal using the envelope tracking decoding operation described herein.

[0107] For example, the first signal can be represented as ,in It is necessary to be in time t The data (e.g., information bits) conveyed for the first signal, and This is the frequency associated with the first signal. The second signal can be represented as... ,in It is necessary to be in time t The data (e.g., information bits) conveyed for the second signal, and It is the frequency associated with the second signal. The signal received at the network entity can be the sum of the first and second signals, such as... The envelope of the received signal can be associated with the square of the received signal. For example, the envelope of the received signal can be represented as... After removing the higher frequency terms of the envelope (e.g., after performing a low-pass filter), the DC voltage of the envelope can be expressed as: Furthermore, the low-frequency term of the envelope can be expressed as Because the DC voltage of the received signal (e.g., the DC term of the envelope) is the sum of the data transmitted via the first and second signals, the network entity may be unable to use envelope tracking to extract or recover the individual signals (e.g., because the envelope includes terms that are the sum of the data transmitted via the first and second signals). Therefore, the communication performance and / or decoding performance associated with the network entity may be degraded because the network entity may incorrectly use envelope tracking to decode a signal when it receives one or more other signals at a time that at least partially overlaps with the time when the signal is received by the network node.

[0108] As indicated above, Figure 5 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 5 The descriptions are different.

[0109] As described elsewhere in this document, an auxiliary signal can be a single tone occupying a subcarrier, a resource element (RE), or another frequency domain resource. An auxiliary signal may occupy a single tone (e.g., a single subcarrier) and may have a fixed or known value or amplitude. In some respects, an auxiliary signal may occupy a single RE. In other respects, an auxiliary signal may be associated with a fixed frequency and / or amplitude.

[0110] Figure 6 This is a diagram illustrating an example of transmission 600, including communication and auxiliary signals, according to this disclosure. Figure 6 As shown, transmission 600 may include data 605 and auxiliary signal 610.

[0111] Data 605 may be associated with data communication or control communication. Data 605 may be associated with IoT communication. For example, transmission 600 may be transmitted via an IoT channel. Transmission 600 may be similar to the above combination. Figure 8 The first signal and / or second signal are described. Data 605 may occupy one or more frequency domain resources (e.g., one or more subcarriers or REs). Data 605 may be associated with frequency locations. Related. Frequency location The auxiliary signal 610 can be the center frequency of one or more frequency domain resources associated with data 605. The auxiliary signal 610 can be a single tone, a single subcarrier, and / or a single RE in the frequency domain, having a constant amplitude or a periodic amplitude that does not transmit information. The auxiliary signal 610 can be used by network entities to isolate received signals (e.g., the envelope of the received signal) from noise or interference signals. In this way, network entities can decode data 605 when multiple transmissions occur simultaneously or at partially overlapping times.

[0112] like Figure 6 As shown, data 605 and auxiliary signal 610 can be separated in the frequency domain by a frequency offset 615. For example, auxiliary signal 610 can be separated from frequency... Related. and The difference can be a frequency offset of 615. The value of the frequency offset of 615 can be selected and / or determined by the network entity (e.g., a network node) that transmits 600. For example, the network entity can determine and / or negotiate the value of the frequency offset of 615 based at least in part on one or more conditions. One or more conditions can increase the value of the frequency offset of 615 to a level sufficient to make items of the received signal (e.g., items of the envelope of the received signal) assist the UE in isolating data 605 signaling from noise and / or interference.

[0113] As indicated above, Figure 6 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 6 The descriptions are different.

[0114] In some aspects described in this paper, network nodes can place two data signals (e.g., repetitions of the same data) at frequencies. At this point, the auxiliary tone is in the middle frequency. In the middle (i.e., The signal sent from a network node can be written as: The envelope at the UE (e.g., after removing higher frequency terms) can be approximated as: ,in , and They are frequencies and Channel gain at that location. The UE (e.g., a tag) can... Frequency shifting application This is followed by low-pass filtering to recover the signal. The detected signal (e.g., )include and Both, and if the channel If it is independent, diversity gain can be implemented at the UE.

[0115] In some aspects, communication may include two auxiliary tones (e.g., auxiliary tones at two different frequency positions). In other aspects, network nodes may place two data signals at frequencies... In the place, the auxiliary tone is place, making In some respects, the frequency offset (e.g., the frequency increment) can be positive at the first or second signal, and negative at the other signal. The signal transmitted from the network node can be written as: The envelope at the UE (e.g., after removing higher frequency terms) can be approximated as: ,in , and They are frequencies and Channel gain at that location. The UE can... Frequency shifting application This is followed by low-pass filtering to recover the signal. The detected signal (e.g., ) may include and Both, and if the channel If it is independent, diversity gain can be implemented at the UE.

[0116] In some cases, in in-band / protected-band deployment scenarios, two IoT data transmissions can be allocated near the two ends of the allocated bandwidth (e.g., 20MHz) to maximize diversity gain.

[0117] In some respects, network nodes can place multiple data signals at different frequencies, each with a corresponding auxiliary tone, such that each auxiliary tone is placed relative to the associated data signal. In these examples, frequency diversity gain can be achieved if the frequency difference between consecutive data tones is greater than the coherence bandwidth of the channel. .

[0118] In some aspects of signals arriving at the UE from multiple network nodes, the UE may be affected by cross-interference at the tag. This can occur, for example, if a neighboring network node's data transmission is closer to the auxiliary tone of the transmission from that network node than the data transmission from the network node. In the example, if the data transmission from the neighboring network node is also closer to the auxiliary tone of the transmission from that network node... If data transmissions from adjacent network nodes occur at a certain location, interference may occur at the UE. Furthermore, if a network node uses multiple data transmissions, the interference will increase.

[0119] To reduce the likelihood of interference from neighboring network nodes, network nodes and their neighbors can communicate with each other to select the transmission frequencies for data and auxiliary tones. However, this choice to reduce interference may introduce an overall constraint on data transmission across all network nodes for a given bandwidth (e.g., minimizing the interval between data and auxiliary tones).

[0120] Network nodes can select the amount of data transmission for each network node based at least in part on the channel gain between the network node and the UE communicating with it. Channel gain can be measured using the backscattered signal from the UE. More data transmission can be allocated to network nodes with lower channel gain (e.g., to increase processing gain at the UE). In some respects, the amount of data transmission can also depend on… Value. After selection among network nodes, each network node can send a value to the associated UE using System Information Block (SIB), Master Information Block (MIB), and / or Physical Broadcast Channel (PBCH), etc. and / or The UE can use the instructions. and / or The value is used to perform data inspection.

[0121] Based at least in part on transmitting data signals at different frequencies while using auxiliary tones, the described techniques can be used to enable the UE to decode communications with improved accuracy using envelope tracking. For example, by using data signals at different frequencies, the UE can benefit from frequency diversity to reduce channel fading effects and other negative channel effects. In this way, the UE can receive communications with a reduced error rate, which saves network, processing, power, and / or communication resources that might otherwise have been consumed by, for example, retransmission of communications for error detection and / or correction until interference is low enough for the UE to identify the information in the communication.

[0122] Figure 7 This is a diagram illustrating example 700 associated with communication using auxiliary tones according to this disclosure. Figure 7 As shown, network nodes (e.g., transmitters, IoT devices, network node 110, CU, DU, and / or RU) can communicate with UEs (e.g., UE 120, tag devices, low-level devices, and / or RedCap devices, etc.). Additionally or alternatively, network nodes can communicate with neighboring network nodes to coordinate the use of auxiliary tones and / or parameters associated with the use of auxiliary tones. In some aspects, transmissions from neighboring network nodes may cause interference and / or noise at the UE's location. In some aspects, network nodes and UEs can be part of a wireless network (e.g., wireless network 100 and / or an IoT network). UEs and network nodes can... Figure 7 The operation shown has been performed with a wireless connection already established.

[0123] As shown by reference numeral 705 in the attached figure, a network node may send configuration information, and a UE may receive such configuration information. In some aspects, the UE may receive the configuration information via one or more of the following: system information (e.g., MIB and / or SIB, etc.), radio resource control (RRC) signaling, one or more media access control (MAC) control elements (CE) and / or downlink control information (DCI), etc.

[0124] In some aspects, the configuration information may indicate one or more candidate configuration and / or communication parameters. In some aspects, these one or more candidate configuration and / or communication parameters may be selected, activated, and / or deactivated by subsequent indications. For example, a subsequent indication may select a candidate configuration and / or communication parameter from the one or more candidate configuration and / or communication parameters. In some aspects, subsequent indications (e.g., the indications described herein) may include dynamic indications, such as one or more MAC CEs and / or one or more DCI messages, etc.

[0125] In some aspects, configuration information may instruct the UE to provide capability reports. In some aspects, configuration information may instruct the UE to use auxiliary tones to receive communication from the network node. In some aspects, configuration information may indicate one or more parameters for using auxiliary tones. For example, one or more parameters may indicate whether data signals are transmitted on different frequencies, whether the same frequency offset is used for data signals on different frequencies, whether the data signals are offset from the same auxiliary signal (e.g., at a single frequency resource), whether the data signals are offset from different auxiliary signals (e.g., the same auxiliary signal on multiple frequency resources), and / or whether the data signals are a repetition of the same data signal or different data signals, etc. In some aspects, the network node may broadcast configuration information.

[0126] The UE can configure itself, at least in part, based on configuration information. In some respects, the UE can be configured to perform one or more of the operations described herein, at least in part, based on configuration information.

[0127] As shown by reference numeral 710 in the attached figure, the UE can send and the network node can receive a capability report. The capability report may indicate whether the UE supports a feature and / or one or more parameters associated with that feature. For example, capability information may indicate the capability and / or parameters for receiving data signals for communication using auxiliary tones. In some aspects, the capability report may indicate whether the UE supports multiple data signals at different frequencies and / or the same data signals at different frequencies. In some aspects, the capability report may indicate whether the UE supports multiple auxiliary tone positions. One or more operations described herein may be based on the capability information in the capability report. For example, the UE may perform communication based on the capability information, or may receive configuration information based on the capability information.

[0128] In some aspects, the configuration information and / or capability report described in conjunction with reference to reference numeral 705 may include information transmitted via multiple communications. Additionally or alternatively, the network node may transmit the configuration information or communications including at least a portion of the configuration information before and / or after the UE transmits the capability report. For example, the network node may transmit a first portion of the configuration information before the capability report, the UE may transmit at least a portion of the capability report, and the network node may transmit a second portion of the configuration information after receiving the capability report.

[0129] As shown by reference numeral 715 in the accompanying drawings, a network node and neighboring network nodes may communicate configurations of one or more auxiliary tones and / or data signals (e.g., associated with communication with the UE). In some aspects, a network node may receive indications of one or more parameters of the configuration from a neighboring network node. Additionally or alternatively, a network node may send indications of one or more parameters of the configuration to a neighboring network node. In some aspects, a network node may indicate a configuration for its own transmissions, and a neighboring network node may indicate a configuration for its own transmissions.

[0130] In some respects, one or more configurations are associated with one or more parameters, such as one or more frequency positions of the data signal, one or more frequency offsets associated with auxiliary tones or one or more additional auxiliary tones, and / or the number of transmissions that the network node and / or neighboring network nodes are permitted to use.

[0131] In some aspects, bandwidth may be at least partially based on cooperation to support a limited number of transmissions to avoid data signals from neighboring network nodes being on frequency resources that are closer to the auxiliary tones of the network nodes than data signals from the network nodes themselves. In some aspects, the number of transmissions supported for transmissions to the network node and neighboring network nodes may be at least partially based on the width of the bandwidth associated with transmissions made by the network node and neighboring network nodes, the frequency offset of the network node, the frequency offset associated with transmissions made by neighboring network nodes, a first channel gain associated with transmissions made by the network node, and / or a second channel gain associated with transmissions made by neighboring network nodes. For example, if the first channel gain is lower than the second channel gain, the higher portion of the total number of transmissions supported for the first network node and neighboring network nodes may be allocated to the first network node. Similarly, if the second channel gain is lower than the first channel gain, the higher portion of the total number of transmissions supported for the first network node and neighboring network nodes may be allocated to the second network node.

[0132] In some aspects, network nodes and neighboring network nodes may negotiate parameters for the corresponding configuration of transmissions by the network node and neighboring network nodes. In some aspects, network nodes and / or neighboring network nodes may identify a first number of data signals permitted for transmission by the network node and / or a second number of adjacent data signals permitted for transmission by the neighboring network node, etc.

[0133] As indicated by reference numeral 720, the UE can receive, and the network node can transmit, an indication of frequency offset for the secondary tone. In some aspects, the network node can transmit the indication of frequency offset in one or more of the SIB, MIB, or PBCH. In this way, the network node can indicate the frequency offset without establishing a link between the network node and the UE. For example, the network node can transmit the indication of frequency offset for the secondary tone without receiving the capability report described in conjunction with reference numeral 710.

[0134] In some respects, an auxiliary tone may be associated with one or more communications (e.g., a single communication or multiple communications separated in the time domain, etc.). An auxiliary tone may be configured to assist the UE in filtering noise (e.g., ambient noise and / or interference from other signals) from data signals associated with data communications. For example, an auxiliary tone may be configured to assist the UE in isolating data signals transmitted by network nodes from data signals transmitted from neighboring network nodes (e.g., interference signals).

[0135] In some aspects, network nodes may transmit indications of frequency offsets via broadcast communication, unicast communication, and / or multicast communication, etc. In some aspects, network nodes may further indicate whether auxiliary tones are to be transmitted at a single location or at multiple locations (e.g., using a first auxiliary tone and a second auxiliary tone).

[0136] As shown by reference numeral 725, the UE can receive and the network node can transmit data communications consisting of one or more auxiliary tones and data signals at different frequencies. In some aspects, the network node can transmit one or more auxiliary tones and data communications within one or more of the SIB, MIB, or PBCH. In this way, the network node can transmit one or more auxiliary tones and data communications without establishing a link between the network node and the UE. For example, the network node can transmit one or more auxiliary tones and data communications without receiving a capability report as described in conjunction with reference numeral 710.

[0137] In some respects, if the UE receives a communication, the network node may send one or more auxiliary tones and data communications as control information to trigger an action by the UE. For example, the communication may instruct the UE to initiate an alarm (e.g., where the UE is a tag or RFID device, etc.).

[0138] In some respects, different frequencies can be based at least in part on the frequency offset of the auxiliary tone. In some respects, the UE can identify the data signal by using the frequency offset and the position of the auxiliary tone. For example, the UE can identify the position of the data signal at least in part based on locating the auxiliary tone and adding and / or subtracting a frequency offset from the position of the auxiliary tone.

[0139] In some aspects, the data signal comprises repetitions of the same set of one or more data signals. For example, the data signal at a first position may be the same as the data signal at a second position. In some aspects, the data signal may be offset from the auxiliary pitch in a positive direction and offset from the auxiliary pitch in a negative direction. For example, the data signal may include a first set of one or more repetitions of one or more data signals at a first frequency offset from the auxiliary pitch offset frequency in a positive direction, and a second set of one or more repetitions of one or more data signals at a second frequency offset from the auxiliary pitch offset frequency in a negative direction.

[0140] In some aspects, the UE may receive one or more repeated first sets of data signals at a first frequency offset from a first auxiliary tone frequency offset carrying an auxiliary tone. The UE may also receive one or more repeated second sets of data signals at a second frequency offset from a second auxiliary tone frequency offset carrying an auxiliary tone (e.g., where the second auxiliary tone frequency is different from the first auxiliary tone frequency). In this way, the UE can use a single frequency offset to isolate different data signals using different locations of the auxiliary signal (e.g., a first auxiliary signal at a first location and a second auxiliary signal at a second location).

[0141] In some aspects, the UE may receive one or more repeated first sets of data signals at a first frequency offset from a first auxiliary tone and a first frequency offset. The UE may also receive one or more repeated second sets of data signals at a second frequency offset from a second auxiliary tone and a second frequency offset (e.g., the second auxiliary tone is located at a different frequency than the first auxiliary tone). In this way, auxiliary tones at different locations may support different signaling, but this is not necessary. For example, a constant "1" auxiliary signal may be associated with the first set of data signals, and alternating "1" and "0" auxiliary signals may be associated with the second set of data signals. The first set of data signals may be the same as or different from the second set of data signals. Additionally or alternatively, the first frequency offset may be the same as or different from the second frequency offset. In this way, the offset of the first set of data signals from the first auxiliary tone may be different from the offset of the second set of data signals from the second auxiliary tone.

[0142] Based at least in part on transmitting data signals at different frequencies while using auxiliary tones, the described techniques can be used to enable the UE to decode communication data signals with improved accuracy. For example, by using data signals at different frequencies, the UE can benefit from frequency diversity to reduce channel fading effects and other negative channel effects. In this way, the UE can receive communications with a reduced error rate, which saves network, processing, power, and / or communication resources that might otherwise have been consumed by, for example, retransmission of communications for error detection and / or correction until interference is low enough for the UE to identify the information in the communication.

Figure 8 In this context, network nodes (e.g., transmitters, IoT devices, network node 110, CU, DU, and / or RU) can communicate with UEs (e.g., UE120, tag devices, low-level devices, and / or RedCap devices, etc.). In some aspects, network nodes and UEs can be part of a wireless network (e.g., wireless network 100 and / or an IoT network). UEs and network nodes can...

[0145] like Figure 8 As shown in Example 800, communication may include a data signal 805 and an auxiliary signal 810. The data signal 805 may be related to frequency position. and Related. For example, the first part of data signal 805 can be... The data is sent from the location, and the second part of the data signal 805 can be sent from there. The first and second parts may include the same signaling (e.g., a repetition of the same set of data signals).

[0146] In some respects, the first part may be offset from the auxiliary signal 810 by an amount equal to the frequency offset 815. The second part may be offset from the auxiliary signal 810 by an amount equal to the frequency offset 825. In some respects, the frequency offset 815 may be equal to the frequency offset 825 (e.g., equal in amplitude and opposite in direction). In some respects, the frequency offset 815 and the frequency offset 825 may be different.

[0147] like Figure 8As shown in Example 830, communication may include a data signal 835 and an auxiliary signal 840. The data signal 835 may be positioned at a frequency offset 845 from the frequency offset of the auxiliary signal 840. Associated. Communication may include a data signal 850 and an auxiliary signal 855. The data signal 850 may be associated with a frequency position offset by 860 from the frequency offset of the auxiliary signal 855. Related.

[0148] In some aspects, frequency offset 845 may be the same value as frequency offset 860. In some aspects, frequency offset 845 and frequency offset 860 may have different values. In some aspects, data signal 835 may be the same data signal as data signal 850. In some aspects, data signal 835 and data signal 850 may be different. In some aspects, auxiliary signal 840 and auxiliary signal 855 may include the same signal at different frequency positions.

[0149] In some respects, the auxiliary signal 840 may be separated from the most recent signal that is not the data signal 835 (e.g., the data signal 850 or the auxiliary signal 855) by a gap 865 greater than the frequency offset 845. In some respects, this amount is at least a threshold amount greater than the frequency offset 845.
