Description

Technical Field

[0001] The following content relates to wireless communication, including conflict management for on / off keying (OOK) signals and reference signals. Background Technology

[0002] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, message sending and receiving, broadcasting, and so on. These systems can support communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple access systems include fourth-generation (4G) systems (such as Long Term Evolution (LTE) systems, LTE-A Advanced (LTE-A) systems, or LTE-A Pro systems) and fifth-generation (5G) systems (which may be referred to as New Radio (NR) systems). These systems may employ technologies such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal FDMA (OFDMA), or Discrete Fourier Transform Extended Orthogonal Frequency Division Multiplexing (DFT-S-OFDM). A wireless multiple access communication system may include one or more base stations, each supporting wireless communication of communication devices, which may be referred to as User Equipment (UE).

[0003] The on / off keying (OOK) signal can be a signal using a simple amplitude shift keying (ASK) modulation scheme, which causes the power level of the OOK signal to vary between two or more discrete power levels. Summary of the Invention

[0004] The described technology relates to improved methods, systems, devices, and apparatuses supporting conflict management for on / off keying (OOK) signals and reference signals. For example, the described technology allows a wireless device to transmit one or more reference signals in bursts of reference signals according to a reference signal configuration. The wireless device can transmit an OOK signal during a portion of the time duration allocated for transmitting the reference signal burst, as indicated by the reference signal configuration as usable for OOK signal transmission. In some examples, according to the reference signal configuration, one or more reference signals can be transmitted via a first resource frequency-division multiplexed (FDMed) with a second resource used for OOK signal transmission. In some examples, the wireless device can send control signaling to an energy harvesting device indicating multiple timings. The control signaling can indicate that a first subset of the multiple timings is one or more OOK timings and a second subset of the multiple timings is a reference signal timing. The wireless device can transmit one or more OOK signals during one or more OOK timings and can transmit one or more reference signals during one or more reference signal timings. The wireless device can monitor messages in response to one or more reference signals, in response to OOK signals, or both.

[0041] The various aspects generally relate to wireless communication, and more specifically to on / off keying (OOK) signal transmission and reference signal transmission. Some aspects more specifically relate to techniques for collision management between the OOK signal and one or more reference signals in a reference signal burst. In some examples, the wireless device can implement a time-domain based collision management process, a frequency-domain based collision management process, or both. To implement the collision management process, the wireless device can send a configuration message to the user equipment (UE) indicating the reference signal configuration. The reference signal configuration can indicate the duration of the reference signal burst and indicate that a portion of the duration can be used for OOK signal transmission. The wireless device can also indicate one or more other parameters to be used in the collision management process via the reference signal configuration, such as OOK signal length, OOK signal periodicity, an index of a lookup table indicating both OOK signal length and OOK signal periodicity, a reduction in the number of reference signals in the reference signal burst, a first resource for transmitting the reference signal, a second resource for transmitting the OOK signal, one or more guard bands between the OOK signal and one or more other signals, the size of the guard band, or another parameter. The wireless device can then send one or more reference signals and OOK signals of the reference signal burst to the second device according to the reference signal configuration, and monitor the response from the second device.

[0042] The conflict management process can also be implemented in an environment-based Internet of Things (A-IoT) scenario where the second device is an energy harvesting device. The wireless device can send control signaling to the energy harvesting device indicating the number of OOK (Out of Memory) timings and the number of reference signal timings. The wireless device can send OOK signals during OOK timings, send reference signals during reference signal timings, and monitor responses from the energy harvesting device.

[0043] Specific aspects of the subject matter described in this disclosure can be implemented to achieve one or more of the following potential advantages. In some examples, by transmitting an OOK signal and one or more reference signals according to a reference signal configuration, the described techniques can be used to reduce or prevent collisions between the OOK signal and one or more reference signals. More specifically, when the wireless device can also transmit the OOK signal, the reference signal transmitted according to the reference signal configuration may be more likely to be successfully received at the second device compared to a reference signal transmitted according to a different reference signal configuration or without a reference signal configuration. By reducing collisions between one or more reference signals and the OOK signal, aspects of this disclosure can achieve more reliable and efficient wireless communication.

[0044] The various aspects of this disclosure are first described in the context of a wireless communication system. These aspects are further described with reference to resource diagrams and process flow diagrams. The various aspects of this disclosure are further illustrated by apparatus diagrams, system diagrams, and flowcharts relating to collision management for OOK signals and reference signals, and are described with reference to these diagrams.

[0045] Figure 1 An example of a wireless communication system 100 supporting collision management for OOK signals and reference signals according to one or more aspects of this disclosure is shown. The wireless communication system 100 may include one or more devices, such as one or more network devices (e.g., network entity 105), one or more UEs 115, and a core network 130. In some examples, the wireless communication system 100 may be a Long Term Evolution (LTE) network, an Advanced LTE (LTE-A) network, an LTE-A Pro network, a New Radio (NR) network, or a network operating under other systems and radio technologies, including future systems and radio technologies not explicitly mentioned herein.

[0046] Network entity 105 may be distributed across a geographical area to form wireless communication system 100, and may include devices employing different forms or having different capabilities. In various examples, network entity 105 may be referred to as a network element, mobility element, radio access network (RAN) node, or network equipment, etc. In some examples, network entity 105 and UE 115 may wirelessly communicate via communication link 125 (e.g., a radio frequency (RF) access link). For example, network entity 105 may support a coverage area 110 (e.g., a geographical coverage area) over which UE 115 and network entity 105 can establish communication link 125. Coverage area 110 may be an example of a geographical area in which network entity 105 and UE 115 may support the transmission of signals according to one or more radio access technologies (RATs).

[0047] UE 115 can be distributed throughout the coverage area 110 of wireless communication system 100, and each UE 115 can be stationary or mobile, or stationary and mobile at different times. UE 115 can be devices in different forms or with different capabilities. Figure 1 Some example UE 115s are illustrated herein. The UE 115 described herein may be able to support, for example, Figure 1 Communication of various types of devices (e.g., including UE 115 or other wireless communication devices of network entity 105) in the wireless communication system 100 shown.

[0048] As described herein, a node in the wireless communication system 100 (which may be referred to as a network node or wireless node) may be a network entity 105 (e.g., any network entity described herein), a UE 115 (e.g., any UE described herein), a network controller, apparatus, device, computing system, one or more components, or another suitable processing entity configured to perform any of the techniques described herein. For example, a node may be UE 115. As another example, a node may be network entity 105. As another example, a first node may be configured to communicate with a second node or a third node. In one aspect of this example, the first node may be UE 115, the second node may be network entity 105, and the third node may be UE 115. In another aspect of this example, the first node may be UE 115, the second node may be network entity 105, and the third node may be network entity 105. In other aspects of this example, the first node, the second node, and the third node may be different from these examples. Similarly, references to UE 115, network entity 105, device, equipment, computing system, etc., may include disclosures of UE 115, network entity 105, device, equipment, computing system, etc., as nodes. For example, a disclosure that UE 115 is configured to receive information from network entity 105 also discloses that a first node is configured to receive information from a second node.

[0049] In some examples, network entity 105 may communicate with core network 130, communicate with each other, or both. For example, network entity 105 may communicate with core network 130 via backhaul communication link 120 (e.g., according to S1, N2, N3, or other interface protocols). In some examples, network entity 105 may communicate with each other directly (e.g., directly between network entities 105) or indirectly (e.g., via core network 130) via backhaul communication link 120 (e.g., according to X2, Xn, or other interface protocols). In some examples, network entity 105 may communicate with each other via midhaul communication link 162 (e.g., according to midhaul interface protocol) or fronthaul communication link 168 (e.g., according to fronthaul interface protocol) or any combination thereof. The backhaul communication link 120, midhaul communication link 162, or fronthaul communication link 168 may be one or more wired links (e.g., electrical links, fiber optic links), one or more wireless links (e.g., radio links, wireless optical links), etc., or various combinations thereof, or may include one or more wired links (e.g., electrical links, fiber optic links), one or more wireless links (e.g., radio links, wireless optical links), etc., or various combinations thereof. UE 115 may communicate with the core network 130 via communication link 155.

[0050] One or more network entities or network equipment described herein as network entity 105 or network equipment may include or be referred to as base station 140 (e.g., transceiver base station, radio base station, NR base station, access point, radio transceiver, NodeB, eNodeB (eNB), next-generation NodeB or gigabit NodeB (any of which may be referred to as gNB), 5G NB, next-generation eNB (ng-eNB), home NodeB, home eNodeB, or other suitable terms). In some examples, network entity 105 (e.g., base station 140) may be implemented in an aggregated (e.g., monolithic, standalone) base station architecture that may be configured to utilize a protocol stack that is physically or logically integrated within a single network entity (e.g., network entity 105 or a single RAN node, such as base station 140).

[0051] In some examples, network entity 105 may be implemented in a decomposed architecture (e.g., a decomposed base station architecture, a decomposed RAN architecture) that can be configured to utilize protocol stacks physically or logically distributed across multiple network entities (e.g., network entity 105) such as an Integrated Access Backhaul (IAB) network, an Open RAN (O-RAN) (e.g., a network configuration sponsored by the O-RAN Alliance), or a Virtualized RAN (vRAN) (e.g., a Cloud RAN (C-RAN)). For example, network entity 105 may include one or more of the following: a Central Unit (CU) such as CU 160, a Distributed Unit (DU) such as DU 165, a Radio Unit (RU) such as RU 170, a RAN Intelligent Controller (RIC) such as RIC 175 (e.g., a near real-time RIC (near RT RIC), a non-real-time RIC (non-RT RIC)), a Service Management and Orchestration (SMO) system such as SMO system 180, or any combination thereof. RU 170 may also be referred to as a radio headend, intelligent radio headend, remote radio headend (RRH), remote radio unit (RRU), or transmit / receive point (TRP). One or more components of network entity 105 in a decomposed RAN architecture may be co-located, or one or more components of network entity 105 may be located in distributed locations (e.g., separate physical locations). In some examples, one or more network entities in network entity 105 of a decomposed RAN architecture may be implemented as virtual units (e.g., virtual CU (VCU), virtual DU (VDU), virtual RU (VRU)).

[0052] The functional splitting among CU 160, DU 165, and RU 170 is flexible and can support different functionalities depending on which functions (e.g., network layer functions, protocol layer functions, baseband functions, RF functions, or any combination thereof) are performed at CU 160, DU 165, or RU 170. For example, a protocol stack functional splitting can be used between CU 160 and DU 165, allowing CU 160 to support one or more layers of the protocol stack, and DU 165 to support one or more different layers of the protocol stack. In some examples, CU 160 can host higher protocol layer (e.g., Layer 3 (L3), Layer 2 (L2)) functionalities and signaling (e.g., Radio Resource Control (RRC), Serving Data Adaptation Protocol (SDAP), Packet Data Convergence Protocol (PDCP)). CU 160 (e.g., one or more CUs) may connect to DU 165 (e.g., one or more DUs) or RU 170 (e.g., one or more RUs) or some combination thereof, and DU 165, RU 170, or both may host lower protocol layers, such as Layer 1 (L1) (e.g., Physical (PHY) layer) or L2 (e.g., Radio Link Control (RLC) layer, Medium Access Control (MAC) layer) functionality and signaling, and may each be at least partially controlled by CU 160. Additionally or alternatively, a functional split of the protocol stack may be employed between DU 165 and RU 170, such that DU 165 may support one or more layers of the protocol stack, and RU 170 may support one or more different layers of the protocol stack. DU 165 may (e.g., via one or more different RUs, such as RU 170) support one or more different cells. In some cases, functional decomposition between CU 160 and DU 165, or between DU 165 and RU 170, can be performed within the protocol layer (e.g., some functions of the protocol layer can be performed by one of CU 160, DU 165, or RU 170, while other functions of the protocol layer can be performed by different of CU 160, DU 165, or RU 170). CU 160 can be further functionally decomposed into CU control plane (CU-CP) functions and CU user plane (CU-UP) functions. CU 160 can be connected to DU 165 via midhaul communication link 162 (e.g., F1, F1-c, F1-u), and DU 165 can be connected to RU 170 via fronthaul communication link 168 (e.g., open fronthaul (FH) interface). In some examples, the midhaul communication link 162 or the fronthaul communication link 168 may be implemented based on the interfaces (e.g., channels) between the layers of the protocol stack, which are supported by corresponding network entities (e.g., one or more network entities in network entity 105) that communicate via such communication links.

[0053] In some wireless communication systems (e.g., wireless communication system 100), the infrastructure and spectrum resources for radio access can support wireless backhaul link capabilities to supplement wired backhaul connections, thereby providing an IAB network architecture (e.g., to core network 130). In some cases, in an IAB network, one or more network entities in network entity 105 (e.g., network entity 105 or IAB node 104) may be partially controlled by each other. IAB node 104 may be referred to as a donor entity or IAB donor. DU 165 or RU 170 may be partially controlled by CU 160 associated with network entity 105 or base station 140 (such as a donor network entity or donor base station). One or more donor entities (e.g., IAB donors) may communicate with one or more additional devices (e.g., IAB node 104) via supported access and backhaul links (e.g., backhaul communication link 120). IAB node 104 may include an IAB mobile terminal (IAB-MT) controlled (e.g., scheduled) by one or more DUs (e.g., DU 165) of a coupled IAB donor. The IAB-MT may be equipped with a separate set of antennas for relaying communication with UE 115, or may share the same antennas (e.g., those of RU 170) for access to IAB node 104 via DU 165 of IAB node 104. (e.g., referred to as a virtual IAB-MT (vIAB-MT)). In some examples, IAB node 104 may include one or more DUs (e.g., DU 165) that support communication links with additional entities (e.g., IAB node 104, UE 115) within a relay chain or configuration (e.g., downstream) of the access network. In such cases, one or more components of the decomposed RAN architecture (e.g., IAB node 104 or components of IAB node 104) may be configured to operate according to the techniques described herein.

[0054] When the techniques described herein are applied in the context of a decomposed RAN architecture, one or more components of the decomposed RAN architecture can be configured to support the tests described herein. For example, some operations described as being performed by UE 115 or network entity 105 (e.g., base station 140) may additionally or alternatively be performed by one or more components of the decomposed RAN architecture (e.g., components such as IAB node, DU 165, CU 160, RU 170, RIC 175, SMO system 180, etc.).

[0055] UE 115 may include or be referred to as a mobile device, wireless device, remote device, handheld device, or subscriber device, or any other suitable term, wherein "device" may also be referred to as a cell, station, terminal, or client, etc. UE 115 may also include or be referred to as a personal electronic device, such as a cellular phone, personal digital assistant (PDA), tablet computer, laptop computer, or personal computer. In some examples, UE 115 may include or be referred to as a wireless local loop (WLL) station, Internet of Things (IoT) device, Internet of Everything (IoE) device, or machine-type communication (MTC) device, etc., which may be implemented in various objects such as appliances or vehicles, meters, etc.

[0056] The UE 115 described herein can communicate with various types of devices, such as the UE 115 which sometimes operates as a relay, and network entity 105 and network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, etc. Figure 1 As shown.

[0057] UE 115 and network entity 105 can wirelessly communicate with each other via communication link 125 (e.g., one or more access links) using resources associated with one or more carriers. The term "carrier" can refer to a set of RF spectrum resources having a defined PHY layer structure for supporting communication link 125. For example, a carrier for communication link 125 may include a portion of the RF spectrum band (e.g., a bandwidth portion (BWP)) operating according to one or more PHY layer channels for a given RAT (e.g., LTE, LTE-A, LTE-A Pro, NR). Each PHY layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling coordinating operation for the carrier, user data, or other signaling. Wireless communication system 100 can support communication with UE 115 using carrier aggregation or multi-carrier operation. Depending on the carrier aggregation configuration, UE 115 can be configured to utilize multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation can be used in conjunction with both frequency division duplex (FDD) component carriers and time division duplex (TDD) component carriers. Communication between network entity 105 and other devices can refer to communication between these devices and any part of network entity 105 (e.g., entity, sub-entity). For example, the terms “send,” “receive,” or “communicate” when referring to network entity 105 can mean that any part of network entity 105 of the RAN (e.g., base station 140, CU 160, DU 165, RU 170) communicates with another device (e.g., directly or via one or more other network entities, such as one or more network entities in network entity 105).

[0058] The signal waveform transmitted via a carrier may include multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques, such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform extended OFDM (DFT-S-OFDM)). In a system employing MCM, a resource element may refer to a resource of one symbol period (e.g., the duration of one modulation symbol) and one subcarrier, where the symbol period and subcarrier spacing may be inversely related. The number of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme, the decoding rate of the modulation scheme, or both), such that a relatively high number of resource elements (e.g., in the transmission duration) and a relatively high modulation scheme order correspond to a relatively high communication rate. Wireless communication resources may refer to a combination of RF spectrum resources, temporal resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial resources may increase the data rate or data integrity used for communication with UE 115.

[0059] The time interval for network entity 105 or UE 115 can be expressed as a multiple of a basic time unit, such as the sampling period. seconds, in response This can represent the supported subcarrier spacing, while This can represent the supported Discrete Fourier Transform (DFT) size. The time interval for organizing communication resources can be based on radio frames, each with a specified duration (e.g., 10 milliseconds (ms)). Each radio frame can be identified by a System Frame Number (SFN) (e.g., ranging from 0 to 1023).

[0060] Each frame may include multiple consecutively numbered subframes or time slots, and each subframe or time slot may have the same duration. In some examples, a frame may (e.g., in the time domain) be divided into subframes, and each subframe may be further divided into a number of time slots. Alternatively, each frame may include a variable number of time slots, and the number of time slots may depend on the subcarrier spacing. Each time slot may include a number of symbol periods (e.g., depending on the length of the cyclic prefix appended to each symbol period). In some wireless communication systems, such as wireless communication system 100, time slots may be further divided into multiple micro-time slots associated with one or more symbols. Excluding the cyclic prefix, each symbol period may be associated with one or more (e.g., The duration of a symbol period is associated with a (number) sampling period. The duration of a symbol period can depend on the subcarrier spacing or the operating frequency band.

[0061] A subframe, time slot, micro-time slot, or symbol can be the smallest scheduling unit of the wireless communication system 100 (e.g., in the time domain) and can be referred to as a transmission time interval (TTI). In some examples, the duration of the TTI (e.g., the number of symbol periods in the TTI) can be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 can be dynamically selected (e.g., in a burst of shortened TTIs (sTTIs)).

[0062] Depending on the technology, carriers can be used to multiplex physical channels for communication. For example, one or more of Time Division Multiplexing (TDM), Frequency Division Multiplexing (FDM), or hybrid TDM-FDM techniques can be used to multiplex physical control channels and physical data channels for signaling via a downlink carrier. The control region (e.g., control resource set (CORESET)) of the physical control channel may be defined by a set of symbol periods and may extend across the system bandwidth of the carrier or a subset of that bandwidth. One or more control regions (e.g., CORESET) can be configured for a set of UEs 115. For example, one or more UEs in UE 115 may monitor or search for control regions to obtain control information based on one or more search space sets, and each search space set may include one or more control channel candidates in one or more aggregation levels arranged in a concatenated manner. The aggregation level of control channel candidates may refer to the amount of control channel resources (e.g., control channel elements (CCEs)) associated with coded information for a control information format having a given payload size. The search space set may include a public search space set configured to transmit control information to UE115 (e.g., one or more UEs), or it may include a UE-specific search space set configured to transmit control information to UE115 (e.g., a particular UE).

[0063] In some examples, network entity 105 (e.g., base station 140, RU 170) can be mobile, and thus provide communication coverage to mobile coverage areas (such as coverage area 110). In some examples, coverage areas 110 associated with different technologies (e.g., different coverage areas) can overlap, but coverage areas 110 (e.g., different coverage areas) can be supported by the same network entity (e.g., network entity 105). In some other examples, overlapping coverage areas (such as coverage area 110) associated with different technologies can be supported by different network entities (e.g., network entity 105). The wireless communication system 100 may include, for example, a heterogeneous network in which different types of network entities 105 use the same or different RATs to support communication for coverage area 110 (e.g., different coverage areas).

[0064] Some UE 115 devices (such as MTC or IoT devices) can be relatively low-cost or low-complexity devices and can provide automated communication between machines (e.g., via machine-to-machine (M2M) communication). M2M communication or MTC can refer to data communication technologies that allow devices to communicate with each other or with network entity 105 (e.g., base station 140) without human intervention. In some examples, M2M communication or MTC may include communication from devices with integrated sensors or instruments to measure or acquire information and relay such information to a central server or application that uses the information or presents it to people interacting with the application. Some UE 115 devices may be designed to collect information or enable automated behavior of machines or other devices. Examples of applications for MTC devices include smart metering, inventory monitoring, water level monitoring, equipment monitoring, healthcare monitoring, wildlife monitoring, weather and geological event monitoring, fleet management and tracking, remote security sensing, physical access control, and transaction-based service charging.

[0065] Wireless communication system 100 may be configured to support ultra-reliable communication or low-latency communication, or various combinations thereof. For example, wireless communication system 100 may be configured to support ultra-reliable low-latency communication (URLLC). UE 115 may be designed to support ultra-reliable, low-latency, or critical functions. Ultra-reliable communication may include private or group communication and may be supported by one or more services, such as push-to-talk, video, or data. Support for ultra-reliable, low-latency functions may include prioritizing services, and such services may be used for public safety or general business applications. The terms “ultra-reliable,” “low-latency,” and “ultra-reliable low-latency” are used interchangeably herein.

[0066] In some examples, UE 115 may be configured to support direct communication with other UEs (e.g., one or more UEs in UE 115) via a device-to-device (D2D) communication link (such as D2D communication link 135) (e.g., according to a peer-to-peer (P2P), D2D, or sidelink protocol). In some examples, one or more UEs 115 in a group performing D2D communication may be within the coverage area 110 of network entity 105 (e.g., base station 140, RU 170), which may support aspects of such D2D communication configured (e.g., scheduled by network entity 105). In some examples, one or more UEs 115 in this group may be outside the coverage area 110 of network entity 105, or may otherwise be unable or not configured to receive transmissions from network entity 105. In some examples, a group of UEs 115 communicating via D2D communication can support a one-to-many (1:M) system, in which each UE 115 transmits to one or more UEs in the group. In some examples, network entity 105 can facilitate the scheduling of resources used for D2D communication. In some other examples, D2D communication can be performed between UEs 115 without involving network entity 105.

[0067] Core network 130 provides user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. Core network 130 can be an evolved packet core (EPC) or a 5G core (5GC), which may include at least one control plane entity (e.g., a mobility management entity (MME), access and mobility management function (AMF)) for managing access and mobility, and at least one user plane entity (e.g., a serving gateway (S-GW), packet data network (PDN) gateway (P-GW), or user plane function (UPF)) for routing packets or interconnecting to external networks. The control plane entity manages non-access stratum (NAS) functions, such as mobility, authentication, and bearer management of UE 115 served by network entity 105 (e.g., base station 140) associated with core network 130. User IP packets can be transferred through user plane entities, which provide IP address allocation and other functions. User plane entities can connect to one or more network operator IP services 150. IP services 150 may include access to the Internet, intranets, IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0068] Wireless communication system 100 can operate using one or more frequency bands in the range of 300 MHz to 300 GHz. Generally, the region from 300 MHz to 3 GHz is referred to as the Ultra High Frequency (UHF) region or decimeter band because the wavelength range is approximately one decimeter to one meter in length. UHF waves may be blocked or redirected by buildings and environmental features (which may be referred to as clusters), but these waves are sufficient to penetrate structures so that macrocells can provide service to UE 115 located indoors. Compared to communication using smaller frequencies and longer wavelengths in the lower frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz, communication using UHF waves can be associated with smaller antennas and shorter ranges (e.g., less than one hundred kilometers).

[0069] Wireless communication system 100 may utilize both licensed and unlicensed RF spectrum bands. For example, wireless communication system 100 may employ licensed assisted access (LAA), LTE-Unlicensed (LTE-U) RAT, or NR technology using unlicensed frequency bands (such as the 5 GHz Industrial, Scientific, and Medical (ISM) band). When operating with unlicensed RF spectrum, devices such as network entity 105 and UE 115 may employ carrier sensing for collision detection and avoidance. In some examples, operation using unlicensed frequency bands may be based on carrier aggregation configurations combined with component carriers operating with licensed frequency bands (e.g., LAA). Operation using unlicensed spectrum may include downlink transmission, uplink transmission, P2P transmission, or D2D transmission, etc.

[0070] Network entity 105 (e.g., base station 140, RU 170) or UE 115 may be equipped with multiple antennas that can be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communication, or beamforming. The antennas of network entity 105 or UE 115 may be located within one or more antenna arrays or antenna panels, which can support MIMO operation or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly (such as an antenna tower). In some examples, the antennas or antenna arrays associated with network entity 105 may be located at different geographical locations. Network entity 105 may include an antenna array having a collection of multiple rows and columns of antenna ports that network entity 105 can use to support beamforming for communication with UE 115. Similarly, UE 115 may include one or more antenna arrays that can support various MIMO or beamforming operations. Additionally or alternatively, the antenna panel may support RF beamforming for signals transmitted via the antenna ports.

[0071] Beamforming (also known as spatial filtering, directional transmission, or directional reception) is a signal processing technique that can be used at a transmitting or receiving device (e.g., network entity 105, UE 115) to shape or guide an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting and receiving devices. Beamforming can be achieved by combining signals transmitted via antenna elements of an antenna array such that some signals propagating along a specific orientation relative to the antenna array experience constructive interference, while other signals experience destructive interference. Adjustments to the signals transmitted via the antenna elements may include applying amplitude shifts, phase shifts, or both to the signals carried via the antenna elements associated with the device. The adjustments associated with each of these antenna elements may be defined by a beamforming weight set associated with a specific orientation (e.g., relative to the antenna array of the transmitting or receiving device or relative to some other orientation).

[0072] In wireless communication system 100, a wireless device (e.g., network entity 105) may transmit one or more OOK signals (e.g., synchronization signals (SS), wake-up signals (WUS), and forward link SS or forward link packets via communication link 125) to UE 115. The OOK signal may be a signal employing a simple amplitude shift keying (ASK) modulation scheme that varies the power level of the OOK signal between two or more discrete power levels. However, in some examples, the transmission of the OOK signal may interfere with important New Radio (NR) and Long Term Evolution (LTE) signals, such as one or more synchronization signal blocks (SSBs), cell-specific reference signals (CRS), tracking reference signals (TRS), positioning reference signals (PRS), channel state information reference signals (CSI-RS), and other reference signals (RS). Interference caused by the OOK signal may prevent the reception of these important reference signals, for example, at UE 115, thereby reducing the reliability and efficiency of wireless communication.

[0073] In some implementations, network entity 105 may transmit multiple reference signals for a reference signal burst according to a reference signal configuration. The reference signal configuration may indicate the duration of the reference signal burst and may indicate that a portion of the duration can be used for OOK signal transmission. Network entity 105 may transmit an OOK signal during the portion of the reference signal burst that can be used for OOK signal transmission, and monitor messages (e.g., from UE 115) in response to one or more reference signals, OOK signals, or both of the multiple reference signals in the reference signal burst. In some examples, the wireless device may transmit a configuration message indicating the reference signal configuration; identifying the length and periodicity of the OOK signal (e.g., by indicating an index in a lookup table); indicating a reduction in the number of reference signals in the reference signal burst relative to a second reference signal configuration (e.g., a previous reference signal configuration); indicating a reduction in the length, periodicity, or both of the OOK signal relative to the second reference signal configuration; or any combination thereof.

[0074] In some implementations, the reference signal configuration may indicate that a first resource used for transmitting reference signal bursts is frequency-division multiplexed with a second resource used for transmitting OOK signals. For example, network entity 105 may transmit multiple reference signals for reference signal bursts via the first resource and transmit the OOK signal via the second resource. In some cases, the subcarrier spacing may be the same for both the OOK signal and the multiple reference signals. In other cases, the subcarrier spacing may be different for both the OOK signal and the multiple reference signals. In such cases, the reference signal configuration may indicate a guard band between the first and second resources, wherein the size of the guard band may be based on a power boost of the OOK signal. Additionally or alternatively, the power spectral density of the OOK signal may be less than or equal to the power spectral density of the multiple reference signals.

[0075] In some implementations, network entity 105 can wirelessly communicate with UE 115, which may be an energy harvesting device (e.g., an A-IoT device). For example, network entity 105 can send control signaling indicating one or more time points (e.g., consecutive time points). The control signaling may indicate that a first subset of the one or more time points is an OOK time point and a second subset of the one or more time points is a reference signal time point. The wireless device may transmit one or more OOK signals during the one or more OOK time points, transmit one or more reference signals during the one or more reference signal time points, and monitor responses from UE 115.

[0076] Figure 2Examples of a wireless communication system 200 supporting collision management for OOK signals and reference signals according to one or more aspects of this disclosure are shown. In some examples, the wireless communication system 200 may implement aspects of the wireless communication system 100. For example, the wireless communication system 200 includes UE 115-a, UE 115-b, and UE 115-c (which may be reference signals). Figure 1 Examples of the corresponding devices described) and wireless device 205 (which may be a reference) Figure 1 Examples of network entity 105 described herein. Additionally or alternatively, UE 115-a, UE 115-b, and UE 115-c, as well as wireless device 205, may each be examples of other types of wireless devices, such as IAB nodes, energy harvesting devices, reader devices, A-IoT devices, low-power wake-up radios (LP-WUR), or other types of transmitters or receivers. Therefore, although aspects of this disclosure are described with reference to UE 115 and wireless device 205, it should be understood that the described techniques may be performed by wireless devices other than UE 115 and network entity 105. As described herein, operations performed by UE 115 and wireless device 205 may be performed by UE 115, network entity 105, or another wireless device, respectively, and the examples shown should not be construed as limiting.

[0077] Devices in wireless communication system 200 may support the transmission and reception of one or more OOK signals 220 (e.g., signals used for synchronization using OOK waveforms), one or more reference signals 215, and one or more other signals. The one or more OOK signals may include low-power synchronization signals (LP-SS), low-power wake-up signals (LP-WUS), A-IoT forward link (FL) SS (e.g., low-power SS), A-IoT FL regular packets, or any combination thereof. Low-power signals may be transmitted via a low-power architecture that may not have a power amplifier (PA), an inverse fast Fourier transform (IFFT), or a phase-locked loop (PLL), and operate at approximately 100 watts. The one or more reference signals may include SSB, CRS, TRS, PRS, CSI-RS, or any combination thereof. For example, the one or more reference signals may be OFDM reference signals. The one or more other signals may include PDCCH, PDSCH, configuration message 210, response message 225, control message 230, another NR or LTE signal, or any combination thereof. In some examples, one or more OOK signals 220 may interfere with one or more reference signals 215 (or one or more other signals). For example, the OOK signal 220 (e.g., LP-SS) may be transmitted at 4.32 MHz at the center of the spectrum, with a duration of 28 OFDM symbols and a period of 320 ms. The reference signal 215 (e.g., SSB) may be transmitted in a 5 ms half-frame with a period of 5 ms between 3 GHz and 6 GHz. The duration of the 16 OFDM symbol reference signal burst may not be long enough to transmit the reference signal without persistent interference (e.g., time-domain interference) between the reference signal 215 and the OOK signal 220, thereby interfering with the reception of the reference signal 215 and reducing the reliability and efficiency of wireless communication.

[0078] In some implementations, wireless device 205 may support a time-domain-based conflict management process. For example, wireless device 205 may transmit (e.g., output) and UE 115-a may receive (e.g., obtain) a configuration message 210 that may indicate a reference signal configuration. In some examples, configuration message 210 may identify the length of OOK signal 220-a (e.g., the number of OFDM symbols), the periodicity of OOK signal 220-a (e.g., in ms), or both. For example, configuration message 210 may indicate an index of a lookup table (e.g., Table 1) that indicates both the length and periodicity of OOK signal 220-a. In one case, configuration message 210 may indicate index '10', which indicates that the length of OOK signal 220-a is 14 OFDM symbols and the periodicity of OOK signal 220-a is 160 ms. In some examples, the lookup table may be configured by RRC, while in others, it may be predefined (e.g., in the standard), and the configuration message 210 (e.g., an RRC message) may indicate the index of the lookup table (e.g., a row index). In some examples (e.g., because the signaling overhead may be small), the payload of the OOK signal 220-a may indicate the decreasing length and decreasing periodicity of the OOK signal 220-a (e.g., by indicating the index of the lookup table).

[0079]

[0080] Table 1: Example Lookup Table

[0081] In some examples, configuration message 210 may indicate a reduction in the number of reference signals 215-a in the reference signal burst relative to the second reference signal configuration (e.g., by indicating the absolute number or relative number of reference signals 215-a) to avoid conflicts between reference signals 215-a and OOK signals 220-a, such as reference... Figure 3 In a more detailed description, additionally or alternatively, configuration message 210 may indicate a reduction in the length of the OOK signal 220-a relative to the second signal configuration (e.g., by indicating the absolute length or relative length of the OOK signal 220-a), a reduction in the periodicity of the OOK signal 220-a (e.g., by indicating the absolute periodicity or relative periodicity of the OOK signal 220-a), or both. That is, configuration message 210 may indicate an increase in the density of OOK signal transmission in the time domain, as referenced... Figure 4To describe in more detail. For example, configuration message 210 may indicate an index of a lookup table that indicates the length and periodicity of the OOK signal 220-a, wherein the second configuration message 210 indicates an index of a lookup table that indicates a relatively long length and a relatively short periodicity of the OOK signal 220-a. In the example, the OOK signal 220-a (e.g., LP-SS) may be shortened from 28 OFDM symbol duration to 14 OFDM symbol duration, the period may be shortened from 320 ms to 160 ms, and the density may be doubled (e.g., 14 OFDM symbol OOK signals are sent every 160 ms instead of 28 OFDM symbol OOK signals every 320 ms).

[0082] According to a reference signal configuration (e.g., as indicated by configuration message 210), wireless device 205 can transmit and UE 115-a can receive one or more reference signals 215-a in a reference signal burst. In some examples, configuration message 210 may indicate the duration of the reference signal burst (e.g., the number of OFDM symbols) and indicate that a portion of the reference signal burst duration can be used to transmit the OOK signal 220-a. In some examples, the portion of the reference signal burst duration that can be used to transmit the OOK signal 220-a may not overlap with one or more reference signals 215-a in the reference signal burst. During the portion of the reference signal burst duration that can be used to transmit the OOK signal 220-a, wireless device 205 can transmit and UE 115-a can receive the OOK signal 220-a. Wireless device 205 may monitor a response message 225-a in response to one or more of the reference signals 215-a, in response to the OOK signal 220-a, or in response to both. In some examples, UE 115-a can send and wireless device 205 can receive a response message 225-a in response to one or more of reference signals 215-a, in response to OOK signal 220-a, or in response to both.

[0083] Additionally or alternatively, in some implementations, wireless device 205 may support a frequency-domain-based conflict management process. For example, configuration message 210 may indicate that a first resource for transmitting a reference signal burst can be frequency-division multiplexed with a second resource for transmitting an OOK signal. According to configuration message 210 (e.g., at a period of 320ms), wireless device 205 may transmit one or more reference signals 215-a of the reference signal burst via the first resource and transmit one or more OOK signals 220 (e.g., OOK signal 220-a) via the second resource, and UE 115-a may receive one or more reference signals 215-a of the reference signal burst via the first resource and receive one or more OOK signals 220 (e.g., OOK signal 220-a) via the second resource, wherein the first and second resources are frequency-division multiplexed, as in the case of a reference signal burst. Figure 5 A more detailed description.

[0084] In some examples, frequency-domain-based collision management processes may lead to persistent time-domain collisions between one or more reference signals 215-a and the OOK signal 220-a. In some examples, inter-parameter set interference may occur when the subcarrier spacing differs for the OOK signal 220-a and one or more reference signals 215-a, resulting in reduced reliability and efficiency of wireless communication. To mitigate such interference, in some examples, the subcarrier spacing may be the same for the OOK signal 220-a and one or more reference signals 215-a. Alternatively, when the subcarrier spacing may differ for the OOK signal 220-a and one or more reference signals 215-a, one or more other measures may be taken to limit inter-parameter set interference.

[0085] In the example, when the subcarrier spacing differs for the OOK signal 220-a (e.g., LP-SS) and one or more reference signals 215-a (e.g., SSB), the reference signal configuration indicated by configuration message 210 can indicate a guard band between the first resource and the second resource. The guard band (e.g., a gap in the frequency domain) can protect one or more reference signals 215-a from interference caused by collisions with the OOK signal 220-a. In some examples, the guard band can be pre-configured (e.g., in the standard). In some examples, configuration message 210 can indicate a second guard band between another signal (e.g., PDSCH or PDCCH) and the OOK signal 220-a, as described in more detail with reference to Figure 6B. In some examples, the downlink PDSCH or PDCCH can be transmitted in the guard band between one or more reference signals 215-a and the OOK signal 220-a, as described in more detail with reference to Figure 6A. In some examples, configuration message 210 can indicate the size of the guard band. In some cases, the size of the guard band can be based on the power boost of the OOK signal 220-a. For example, a relatively large power boost of the OOK signal 220-a can be associated with a relatively large guard band size.

[0086] Additionally or alternatively, when the subcarrier spacing differs for the OOK signal 220-a (e.g., LP-SS) and one or more reference signals 215-a (e.g., SSB), the power spectral density (e.g., energy per resource element (EPRE)) of the OOK signal 220-a may be less than or equal to the power spectral density of one or more reference signals 215-a, in order to reduce inter-parameter set interference when the subcarrier spacing may differ for the frequency division multiplexed OOK signal 220-a and one or more reference signals 215-a.

[0087] Wireless device 205 can monitor response message 225-a in response to one or more of reference signals 215-a, in response to OOK signal 220-a, or in response to both. In some examples, UE 115-a can send and wireless device 205 can receive response message 225-a in response to one or more of reference signals 215-a, in response to OOK signal 220-a, or in response to both.

[0088] Additionally or alternatively, in some implementations, when UE 115-a can be LP-WUS, radio device 205 may support a collision management procedure. For example, a single paging opportunity may include multiple PDCCH monitoring opportunities, which may be discontinuous in the time domain. The number of PDCCH monitoring opportunities may be equal to the number of reference signals transmitted in a reference signal burst. The TF of the Early Paging Indication (PEI) (e.g., via DCI) may be in the corresponding coreset search space (e.g., 1 to 3 symbols in the time domain). In such LP-WUS scenarios, time-domain based collision management procedures and frequency-domain based collision management procedures can be applied to reduce collisions between one or more reference signals and the OOK signal.

[0089] Additionally or alternatively, in some implementations, wireless device 205 may support conflict management procedures for A-IoT scenarios (e.g., when the signal is aperiodic or semi-periodic). For example, wireless device 205 may communicate with UE 115-b (which may be an energy harvesting device) (e.g., via a forward link packet), and UE 115-b may communicate with UE 115-c (which may be a reader device) (e.g., via a backscatter link or reverse link). The forward link packet may contain hundreds of bits, and UE 115-b may monitor aperiodic responses from reader UE 115-c. Therefore, UE 115-b may continuously monitor hundreds of symbols.

[0090] In some examples, wireless device 205 can transmit and UE 115-b can receive control signaling indicating multiple timings (e.g., consecutive timings, A-IoT timings). The control signaling may indicate that a first subset of the multiple timings is one or more OOK timings and a second subset of the multiple timings is one or more reference signal timings.

[0091] In some examples, control signaling may be a single control message 230-a indicating one or more OOK timings and one or more reference signal timings. For example, control message 230-a may indicate an index of a bitmap that indicates one or more OOK timings and one or more reference signal timings. In some examples, control signaling may include more than one control message 230. For example, wireless device 205 may transmit and UE 115-b may receive a first control message 230-a indicating multiple timings and a second control message 230-b indicating one or more reference signal timings. In such examples, UE 115-b may assume that the remaining timings among the multiple timings not indicated as reference signal timings are OOK timings.

[0092] During one or more OOK time opportunities, radio device 205 may transmit and UE 115-b may receive one or more OOK signals 220 (e.g., OOK signal 220-b). In some examples, radio device 205 may suppress transmission during one or more OOK time opportunities based on the occurrence of two or more reference signal time opportunities within a defined time duration, such as reference... Figure 7 A more detailed description. The defined time duration can be the number of time slots and can be indicated via control signaling (e.g., control message 230-a or control message 230-b).

[0093] During one or more reference signal timing periods, wireless device 205 may transmit and UE 115-b may receive one or more reference signals 215-b. Wireless device 205 may monitor response messages 225-b (e.g., OOK signal 220-b) from UE 115-b in response to one or more OOK signals 220 (e.g., OOK signal 220-b), in response to one or more reference signals 215-b, or in response to both. In some examples, UE 115-b may transmit and wireless device 205 may receive response messages 225-b in response to OOK signal 220-b, in response to one or more reference signals 215-b, or in response to both.

[0094] Figure 3 An example of resource diagram 300 supporting conflict management for OOK signals and reference signals according to one or more aspects of this disclosure is shown. Resource diagram 300 can implement separate references. Figure 1 and Figure 2 The described wireless communication system 100 and wireless communication system 200 may be one or more aspects thereof, or implemented therein. For example, resource diagram 300 may be derived from, as referenced... Figure 1 and Figure 2 The described wireless device 205 (e.g., network entity 105) and UE 115 are implemented to support the conflict management process.

[0095] For example, resource map 300 can be utilized during a time-domain-based conflict management process. A wireless device (e.g., wireless device 205) can transmit (e.g., output) and a UE (e.g., UE 115-a) can receive (e.g., acquire) a first configuration message indicating a first reference signal configuration. The first reference signal configuration can indicate a first reference signal burst 305-a, a reference signal burst duration 310, and a first number (e.g., 8 reference signals) of reference signals 315 within the first reference signal burst 305-a. In some examples, the first configuration message can indicate that a portion of the reference signal burst duration 310 can be used to transmit a first OOK signal 320 within the reference signal burst 305-a (e.g., a portion that does not overlap with reference signals 315). The first reference signal configuration can identify a first OOK signal length 325-a (e.g., 14 OFDM symbols). According to the first reference signal configuration indicated by the first configuration message (e.g., having a first reference signal burst duration 310 and a first OOK signal length 325-a), the wireless device can transmit and the UE can receive the reference signal 315 and the OOK signal 320 in the first reference signal burst 305-a.

[0096] In some examples, a wireless device (e.g., wireless device 205) can transmit and a UE (e.g., UE 115-a) can receive a second configuration message indicating a second reference signal configuration. The second reference signal configuration may indicate a second reference signal burst 305-b, a second reference signal burst duration 310, and a second number (e.g., 6 reference signals) of reference signals 315 in the second reference signal burst 305-b. In some examples, the second configuration message may indicate that a portion of the reference signal burst duration 310 can be used to transmit a second OOK signal 320 in the reference signal burst 305-b (e.g., a portion that does not overlap with reference signal 315). The second reference signal configuration may identify a second OOK signal length 325-b (e.g., 28 OFDM symbols). Based on the second reference signal configuration indicated by the second configuration message (e.g., having a second reference signal burst duration 310 and a second OOK signal length 325-b), the wireless device can transmit and the UE can receive reference signals 315 and OOK signals 320 in the second reference signal burst 305-b.

[0097] In some examples, the second configuration message may indicate a reduction in the number of reference signals 315 in reference signal burst 305-b relative to the number of reference signals 315 in reference signal burst 305-a indicated by the first configuration message. In some examples, the second configuration message may indicate the absolute number of reference signals 315 (e.g., 6 reference signals), while in other examples, the second configuration message may indicate the relative number of reference signals 315 relative to the second configuration message (e.g., 2 reference signals 315, i.e., 2 fewer reference signals 315 than the number indicated by the first configuration message). Additionally or alternatively, the second configuration message may indicate a change in the OOK signal length 325-b relative to the OOK signal length 325-a indicated by the first configuration message. In some examples, the second configuration message may indicate an absolute OOK signal length of 325-b (e.g., 28 OFDM symbols), while in other examples, the second configuration message may indicate a relative OOK signal length of 325-b relative to the second configuration message (e.g., 14 more OFDM symbols than the first OOK signal length of 325-a, or twice the first OOK signal length of 325-a indicated by the first configuration message). In some examples, the OOK signal length of 325-a may be the same as the OOK signal length of 325-b, as indicated by the second configuration message.

[0098] By reducing the number of reference signals 315 transmitted in reference signal burst 305-b, the wireless device can reduce or prevent collisions between reference signals 315 and OOK signals 320, thereby improving the reliability and efficiency of wireless communication with UE 115.

[0099] In some examples, the second configuration message (e.g., second reference signal configuration) may indicate a decrease in the OOK signal length 325-b and a periodic decrease in the OOK signal, as in the reference... Figure 4 A more detailed description.

[0100] Figure 4 An example of a resource diagram 400 supporting conflict management for OOK signals and reference signals according to one or more aspects of this disclosure is shown. Resource diagram 400 can implement separate references... Figure 1 and Figure 2 The described wireless communication system 100 and wireless communication system 200 may be one or more aspects thereof, or implemented therein. For example, resource diagram 400 may be derived from, as referenced Figure 1 and Figure 2 The described wireless device 205 (e.g., network entity 105) and UE 115 are implemented to support the conflict management process.

[0101] For example, resource map 400 can be utilized during a time-domain-based conflict management process. A wireless device (e.g., wireless device 205) can transmit (e.g., output) and a UE (e.g., UE 115-a) can receive (e.g., acquire) a first configuration message indicating a first reference signal configuration. The first reference signal configuration can indicate a first set of reference signal bursts 405-a, the duration of the first reference signal burst, and a first number of reference signals 415 in reference signal burst 405-a (e.g., 6 reference signals). In some examples, the first configuration message can indicate that a portion of the reference signal burst duration can be used to transmit a first OOK signal 420 in reference signal burst 405-a (e.g., a portion that does not overlap with reference signal 415). The first reference signal configuration can identify a first OOK signal length 425-a (e.g., 28 OFDM symbols) and a first OOK signal periodicity 410-a (e.g., 320 ms). According to the first reference signal configuration indicated by the first configuration message (e.g., having a first OOK signal periodicity 410-a and a first OOK signal length 425-a), the wireless device can transmit and the UE can receive the reference signal 415 and the OOK signal 420 in the first reference signal burst 405-a. According to the first reference signal configuration indicated by the first configuration message (e.g., having a first OOK signal length 425-a and a first OOK signal periodicity 410-a), the wireless device can transmit and the UE can receive the reference signal 415 and the OOK signal 420 in the first set of reference signal bursts 405-a.

[0102] In some examples, a wireless device (e.g., wireless device 205) can transmit and a UE (e.g., UE 115-a) can receive a second configuration message indicating a second reference signal configuration. The second reference signal configuration may indicate a second set of reference signal bursts 405-b, a second reference signal burst duration, and a second number (e.g., 8 reference signals) of reference signals 415 in the second reference signal burst 405-b. In some examples, the second reference signal burst duration may be the same as the first reference signal burst duration, as indicated by the second configuration message. In some examples, the second configuration message may indicate that a portion of the reference signal burst duration can be used to transmit a second OOK signal 420 in reference signal burst 405-b (e.g., a portion that does not overlap with reference signal 415). The second reference signal configuration may identify a second OOK signal length 425-b (e.g., 14 OFDM symbols) and a second OOK signal periodicity 410-b (e.g., 160 ms). According to the second reference signal configuration indicated by the second configuration message (e.g., having a second OOK signal periodicity 410-b and a second OOK signal length 325-b), the wireless device can transmit and the UE can receive the reference signal 415 and the OOK signal 420 in the second set of reference signal bursts 405-b. According to the second reference signal configuration indicated by the second configuration message (e.g., having a second OOK signal length 425-b and a second OOK signal periodicity 410-b), the wireless device can transmit and the UE can receive the reference signal 415 and the OOK signal 420 in the second set of reference signal bursts 405-b.

[0103] In some examples, the second configuration message may indicate a reduction in the OOK signal length 425-b relative to the OOK signal length 425-a, a reduction in the OOK signal periodicity 410-b relative to the OOK signal periodicity 410-a, or both. In some examples, the second configuration message may indicate an absolute OOK signal length 425-b (e.g., 14 OFDM symbols), while in other examples, the second configuration message may indicate a relative OOK signal length 425-b relative to the second configuration message (e.g., 14 fewer OFDM symbols than the first OOK signal length 425-a, or half the first OOK signal length 425-a indicated by the first configuration message). Additionally or alternatively, the second configuration message may indicate an absolute OOK periodicity 410-b (e.g., 160 ms), while in other examples, the second configuration message may indicate a relative OOK periodicity 410-b relative to the second configuration message (e.g., 160 ms less than the first OOK periodicity 410-a, or half the number of ms indicated by the first configuration message).

[0104] Additionally or alternatively, the second configuration message may indicate a lookup table (e.g., reference). Figure 2 The index described in Table 1 indicates both the OOK signal length 425-b and the OOK signal periodicity 410-b. In one case, the second configuration message may indicate index '10', which indicates that the OOK signal length 425-b is 14 OFDM symbols and the OOK signal periodicity 410-b is 160 ms. In some examples, the lookup table may be RRC-configured, while in other examples, the lookup table may be predefined (e.g., in the standard), and the second configuration message (e.g., an RRC message) may indicate the index of the lookup table (e.g., the row index). In some examples (e.g., because the signaling overhead may be small), the OOK signal 420 payload may indicate a reduced OOK signal length 425-b and a reduced OOK signal periodicity 410-b (e.g., by indicating the index of the lookup table).

[0105] By reducing the OOK signal length 425-b and the OOK signal periodicity 410-b (e.g., increasing the OOK signal density in the time domain), the wireless device can reduce or prevent the collision between the reference signal 415 and the OOK signal 420, thereby improving the reliability and efficiency of wireless communication with the UE115.

[0106] Figure 5 An example of a resource diagram 500 supporting conflict management for OOK signals and reference signals according to one or more aspects of this disclosure is shown. Resource diagram 500 can implement separate references... Figure 1 and Figure 2 The described wireless communication system 100 and wireless communication system 200 may be one or more aspects thereof, or implemented therein. For example, resource diagram 500 may be derived from, as referenced Figure 1 and Figure 2 The described wireless device 205 (e.g., network entity 105) and UE 115 are implemented to support the conflict management process.

[0107] For example, resource map 500 can be utilized during a frequency-domain-based conflict management process. A wireless device (e.g., wireless device 205) can transmit (e.g., output) and a UE (e.g., UE 115-a) can receive (e.g., acquire) a configuration message indicating a reference signal configuration. In some examples, the configuration message may indicate that a first resource 505-a for transmitting a reference signal burst set 515 can be frequency-division multiplexed with a second resource 505-b for transmitting an OOK signal set 520. In some examples, the configuration message may indicate periodicity 510 (e.g., OOK signal periodicity, reference signal burst periodicity, or both). According to a configuration message (e.g., periodic 510 of 320ms), the wireless device can transmit one or more reference signals of reference signal burst set 515 via first resource 505-a and transmit one or more OOK signals of OOK signal set 520 via second resource 505-b, and the UE can receive one or more reference signals of reference signal burst set 515 via first resource 505-a and receive one or more OOK signals of OOK signal set 520 via second resource 505-b, wherein the first resource 505-a and the second resource 505-b are frequency-division multiplexed, as in the reference signal burst set 515. Figure 2 A more detailed description.

[0108] In some examples, frequency-domain-based collision management processes may lead to persistent time-domain collisions between one or more reference signals of reference signal burst set 515 and one or more OOK signals of OOK signal set 520. In some examples, inter-parameter set interference may occur when the subcarrier spacing differs for OOK signal set 520 and reference signal burst set 515, resulting in reduced reliability and efficiency of wireless communication. To mitigate such interference, in some examples, the subcarrier spacing may be the same for OOK signal set 520 and reference signal burst set 515. Alternatively, when the subcarrier spacing may differ for OOK signal set 520 and reference signal burst set 515, one or more other measures may be taken to limit inter-parameter set interference, as described in more detail with reference to Figures 6A and 6B.

[0109] Figures 6A and 6B illustrate examples of resource diagrams 601 and 602 supporting conflict management for OOK signals and reference signals according to one or more aspects of this disclosure. Resource diagrams 601 and 602 can implement separate reference signals. Figure 1 and Figure 2 The described wireless communication system 100 and wireless communication system 200 may be one or more aspects thereof, or implemented therein. For example, resource diagrams 601 and 602 may be derived from, as referenced... Figure 1 and Figure 2 The described wireless device 205 (e.g., network entity 105) and UE 115 are implemented to support the conflict management process.

[0110] For example, resource maps 601 and 602 can be utilized during a frequency-domain-based conflict management process. A wireless device (e.g., wireless device 205) can transmit (e.g., output) and a UE (e.g., UE 115-a) can receive (e.g., acquire) a configuration message indicating a reference signal configuration. In some examples, the configuration message can indicate that a first resource for transmitting one or more reference signals 615 of a reference signal burst can be frequency-division multiplexed with a second resource for transmitting an OOK signal 620. According to the configuration message, the wireless device can transmit one or more reference signals 615 of a reference signal burst via the first resource and transmit one or more OOK signals 620 via the second resource, and the UE can receive one or more reference signals 615 of a reference signal burst via the first resource and receive one or more OOK signals 620 via the second resource, wherein the first and second resources are frequency-division multiplexed, as in the reference... Figure 5 A more detailed description.

[0111] In some examples, frequency-domain-based collision management processes may lead to persistent time-domain collisions between one or more reference signals 615 and the OOK signal 620. In some examples, inter-parameter set interference may occur when the subcarrier spacing differs for the OOK signal 620 and one or more reference signals 615, resulting in reduced reliability and efficiency of wireless communication. To mitigate such interference, in some examples, the subcarrier spacing may be the same for the OOK signal 620 and one or more reference signals 615. Alternatively, when the subcarrier spacing may differ for the OOK signal 620 and one or more reference signals 615, one or more other measures may be taken to limit inter-parameter set interference.

[0112] In the example, when the subcarrier spacing differs for the OOK signal 620 and one or more reference signals 615, the reference signal configuration indicated by the configuration message can indicate a guard band 605-a between the first resource and the second resource, as illustrated in resource diagram 601. The guard band 605-a (e.g., a gap in the frequency domain) can protect one or more reference signals 615-a from interference caused by collisions with the OOK signal 620-a (rather than protecting the OOK signal 620-a for reception by the OOK receiver). Additionally or alternatively, the guard band 605-a can be pre-configured (e.g., in the standard). In some examples, another signal (e.g., PDSCH 610-a, PDCCH, or another downlink OFDM signal that may cause less interference than the OOK signal 620-a) can be transmitted in the guard band 605-a between one or more reference signals 615-a and the OOK signal 620-a (e.g., making the guard band not empty). In some examples, guard band 605-a may be used to protect reference signal 615-a (e.g., for SSB protection), which differs from the guard band used to receive OOK signals (e.g., different in size; in the guard band, only one side of the guard band, PDCCH, PDSCH, etc., may be transmitted). In some examples, configuration messages may indicate the size of guard band 605-a (or one or more other guard bands 605). In some cases, the size of guard band 605-a may be based on a power boost of OOK signal 620-a. For example, a relatively large power boost of OOK signal 620-a (e.g., LP-SS) may be associated with a relatively large size of guard band 605-a.

[0113] Additionally or alternatively, when the subcarrier spacing differs for the OOK signal 620 and one or more reference signals 615, the power spectral density (e.g., EPRE) of the OOK signal 620-a may be less than or equal to the power spectral density of one or more reference signals 615-a (e.g., the power difference between the OOK signal 620-a and one or more reference signals 615-a may be reduced by a certain number of dB or eliminated) to reduce inter-parameter set interference when the subcarrier spacing may differ for the frequency-division multiplexed OOK signal 620-a and one or more reference signals 615-a. In some examples, the configuration message may indicate a guard band 605 between another signal (e.g., PDSCH or PDCCH) and the OOK signal 620. For example, as illustrated in resource figure 602, in scenarios where the subcarrier spacing differs for the OOK signal 620 and one or more reference signals 615, the configuration message may indicate a first guard band 605-b between PDSCH 610-b and the OOK signal 620-b, and may indicate a second guard band 605-c between PDSCH 610-c and the OOK signal 620-b. In some examples, guard band 605-b or guard band 605-c can aid in the reception of the OOK signal 620, where such guard bands can be used to assist reception by the baseband low-pass filter (BB-LPF) of the OOK receiver.

[0114] By introducing one or more guard bands 605 between the OOK signal 620 and one or more other signals (e.g., PDSCH 610 and reference signal 615), wireless devices can reduce interference and improve the reliability and efficiency of wireless communication.

[0115] Figure 7 An example of resource diagram 700 supporting conflict management for OOK signals and reference signals according to one or more aspects of this disclosure is shown. Resource diagram 700 can implement separate references. Figure 1 and Figure 2 The described wireless communication system 100 and wireless communication system 200 may be one or more aspects thereof, or implemented therein. For example, resource diagram 700 may be derived from, as referenced Figure 1 and Figure 2 The described wireless device 205 (e.g., network entity 105) and UE 115 are implemented to support the conflict management process.

[0116] For example, resource graph 700 can be utilized during the conflict management process for A-IoT scenarios, which can be a reference. Figure 2This is an extension of the conflict management process described in Figure 6 for an OOK signal (e.g., LP-SS) and one or more reference signals. The conflict management process for A-IoT scenarios can differ from LP-SS or LP-WUS scenarios, which are primarily periodic. In contrast, A-IoT scenarios can involve aperiodic signals or semi-periodic symbols. For example, a wireless device can communicate with an energy harvesting UE (e.g., an energy harvesting device or an A-IoT device) (e.g., via a forward link packet). Additionally or alternatively, the UE can communicate with a reader UE (e.g., a reader device) (e.g., via a backscatter link or a reverse link). The forward link packet can contain up to hundreds of bits, and the energy harvesting UE (e.g., device type C) can monitor (e.g., wait for) one or more aperiodic responses from the reader UE. Thus, the energy harvesting UE can continuously monitor hundreds of symbols.

[0117] In some specific implementations, wireless devices can be based on references Figure 1 The time-domain conflict management process (e.g., time-domain solution) is implemented using the time-domain conflict management process (e.g., time-domain solution) described in Figure 6 for LP-SS and LP-WUS. For example, a wireless device can configure an energy harvesting UE (e.g., an A-IoT device) with A-IoT timings, where some symbols are excluded (e.g., occupied by important NR or LTE reference signals). That is, the wireless device can transmit and the energy harvesting UE can receive control signaling indicating multiple timings (e.g., consecutive timings, A-IoT timings). The control signaling can indicate that a first subset of the multiple timings is one or more OOK timings and a second subset of the multiple timings is one or more reference signal timings.

[0118] In some examples (e.g., the first option), the wireless device can select a specific timing (e.g., occupied by a reference signal such as an SSB) and allocate the remaining timings to the energy harvesting UE (e.g., an A-IoT device). That is, control signaling can be a single control message indicating one or more OOK timings and one or more reference signal timings. For example, the control message could indicate an index of a bitmap that indicates one or more OOK timings and one or more reference signal timings. The wireless device can reuse the reference... Figure 1 The solutions described in Figure 6 (e.g., conflict management processes) include a single configuration message and a bitmap or lookup table to indicate the length and periodicity of the OOK signal.

[0119] In some examples (e.g., the second option), the wireless device may configure the energy harvesting device with consecutive timings, and may configure a subset of these timings (e.g., timings occupied by a reference signal (such as an SSB)) to be selected. That is, control signaling may include more than one control message (e.g., two separate signaling messages). For example, the wireless device may send, and the energy harvesting UE may receive, a first control message indicating multiple timings and a second control message indicating one or more reference signal timings (e.g., a new time-domain mode configuration). In such examples, the energy harvesting UE may assume that the remaining timings among the multiple timings not indicated as reference signal timings are OOK timings.

[0120] The wireless device may transmit one or more OOK signals 720 (e.g., OOK signals 720-a, 720-b, and 720-c) during one or more OOK time periods, and the energy harvesting UE may receive one or more OOK signals 720 (e.g., OOK signals 720-a, 720-b, and 720-c) during one or more OOK time periods, and the wireless device may transmit one or more reference signals 715 (e.g., reference signals 715-a and 715-b) during one or more reference signal time periods.

[0121] In some examples, if two important reference signals are close together in the time domain, the wireless device can skip the time slot between the two important reference signals. The proximity of the two reference signals can be refined by a number of time slots of X (e.g., 2 time slots), such that if the distance between the two reference signals (e.g., two SSBs) is less than or equal to X time slots, the OOK signal can skip the time slot between the two SSBs. That is, control signaling can define a time duration of 725 (e.g., the number of time slots, such as 2 time slots). In some other examples, the time duration of 725 can be predefined (e.g., in the standard, or via other signaling). The wireless device can suppress transmission in one or more of the one or more OOK time slots based on the occurrence of two or more reference signal time slots within the defined time duration of 725. For example, a wireless device may suppress the transmission of OOK signal 720-b based on the occurrence of reference signal 715-a and reference signal 715-b within a time duration of 725 (e.g., the distance between reference signal 715-a and reference signal 715-b is less than or equal to the number of time slots indicated by the time duration of 725).

[0122] The wireless device can monitor response messages (e.g., backscatter response messages) from the energy harvesting UE in response to one or more OOK signals 720 (e.g., OOK signals 720-a and 720-b), one or more reference signals 715 (e.g., reference signals 715-a and 715-b), or both. In some examples, the energy harvesting UE can send and the wireless device can receive response messages in response to OOK signals 720, one or more reference signals 715, or both.

[0123] By suppressing the transmission of the OOK signal 720, the wireless device can reduce or prevent collisions between the OOK signal 720 and the reference signal 715. The energy harvesting UE can also monitor fewer resources. Therefore, wireless communication between the wireless device and the energy harvesting UE can be more efficient and reliable.

[0124] Figure 8 An example of a process flow 800 supporting conflict management for OOK signals and reference signals according to one or more aspects of this disclosure is shown. In some examples, process flow 800 may be implemented by wireless communication system 100 and wireless communication system 200, as well as resource diagrams 300, 400, 500, 601, 602, and 700, or aspects thereof. For example, process flow 800 includes wireless device 805 (which may be an example of network entity 105) and UE 115-d, which may be reference signals. Figure 1 and Figure 2 Examples of the corresponding devices described. After process flow 800, wireless device 805 can avoid collisions between the transmitted OOK signal and the reference signal. The following alternative examples can be implemented, some of which may be performed in a different order than described or not at all. In some cases, steps may include additional features not mentioned below, or other steps may be added. Although UE 115-d and wireless device 805 are shown as performing the operation of process flow 800, some aspects of some operations may also be performed by one or more other wireless devices.

[0125] In some examples, radio device 805 and UE 115-d can implement a time-domain-based collision management process. For example, at 810, radio device 805 can transmit (e.g., output) and UE 115-d can receive (e.g., acquire) a configuration message indicating a reference signal configuration. The reference signal configuration can identify the length of the OOK signal, the periodicity of the OOK signal, or both. In some examples, the configuration message can indicate an index of a lookup table. The index of the lookup table can indicate both the length of the OOK signal and the periodicity of the OOK signal. The configuration message can indicate a reduction in the number of reference signals in a reference signal burst relative to a second reference signal configuration. That is, the second reference signal configuration can indicate a second number of reference signals, and the first reference signal configuration can indicate a first number of reference signals, wherein the configuration message can indicate the first number of reference signals, and wherein the first number of reference signals is an absolute number less than or equal to the second number of reference signals. Additionally or alternatively, the configuration message can indicate a relative number of reference signals. In other words, if the second reference signal configuration indicates eight reference signals and the configuration message indicates that the relative number of reference signals is two, then the actual number of reference signals sent can be six (e.g., two less than eight).

[0126] In some examples, the configuration message may indicate the length of the OOK signal, the periodicity of the OOK signal, or a reduction of both relative to the second reference signal configuration. The configuration message may indicate: the absolute length of the OOK signal, which is less than or equal to the length of the OOK signal indicated by the second reference signal configuration; the relative length of the OOK signal relative to the second reference signal configuration; the absolute periodicity of the OOK signal, which is less than or equal to the periodicity of the OOK signal indicated by the second reference signal configuration; the relative periodicity of the OOK signal relative to the second reference signal configuration; or any combination thereof.

[0127] At 815, depending on the reference signal configuration, radio device 805 can transmit and UE 115-d can receive multiple reference signals in a reference signal burst. In some examples, the reference signal configuration transmitted at 805 can indicate the duration of the reference signal burst and indicate that a portion of the duration can be used for OOK signal transmission. The portion of the duration of the reference signal burst that can be used for OOK signal transmission may not overlap with the multiple reference signals. In some examples, the multiple reference signals may include SSB, CRS, TRS, PRS, CSI-RS, or combinations thereof. The OOK signal may be one of SS, WUS, forward link SS, or forward link packet.

[0128] At 820, during a portion of the duration of the reference signal burst that can be used for OOK signal transmission, wireless device 805 can transmit and UE 115-d can receive the OOK signal.

[0129] At 825, the wireless device 805 can monitor one or more of a plurality of reference signals in response to a reference signal burst, in response to an OOK signal, or in response to both.

[0130] At 830, UE 115-d can transmit (e.g., output) and wireless device 805 can receive (e.g., acquire) one or more reference signals in response to a reference signal burst, a response message in response to an OOK signal, or a response message in response to both.

[0131] In some examples, radio device 805 and UE 115-d can implement a frequency-domain-based conflict management process. For example, at 835, based on a reference signal configuration (e.g., a reference signal configuration sent via a configuration message at 810), radio device 805 can transmit multiple reference signals of a reference signal burst via a first resource, and UE 115-d can receive multiple reference signals of the reference signal burst via the first resource. The reference signal configuration can instruct the first resource used for reference signal burst transmission to be frequency-division multiplexed with a second resource used for OOK signal transmission.

[0132] At 840, radio device 805 can transmit an OOK signal via a second resource, and UE 115-d can receive the OOK signal via the second resource. In some examples, the subcarrier spacing can be the same for the OOK signal and one or more of the multiple reference signals. In some other examples, the subcarrier spacing can be different for the OOK signal and one or more of the multiple reference signals. In those cases, the reference signal configuration can indicate a guard band between the first resource and the second resource. The size of the guard band can be based on the power boost of the OOK signal (e.g., a relatively large power boost can be associated with a relatively large guard band size). In some examples, the power spectral density (e.g., EPRE) of the OOK signal can be less than or equal to the power spectral density (e.g., EPRE) of one or more of the multiple reference signals.

[0133] At 845, the wireless device 805 can monitor one or more of a plurality of reference signals in response to a reference signal burst, or in response to an OOK signal, or in response to both.

[0134] At 850, UE 115-d can transmit and wireless device 805 can receive response messages in response to one or more of a plurality of reference signals in response to a reference signal burst or in response to an OOK signal or both.

[0135] Figure 9An example of a process flow 900 supporting conflict management for OOK signals and reference signals according to one or more aspects of this disclosure is shown. In some examples, process flow 900 may be implemented by wireless communication systems 100 and 200, and resource diagrams 300, 400, 500, 601, 602, and 700, or aspects thereof. For example, process flow 900 includes wireless device 905 (e.g., network entity 105) and UE 115-e (e.g., energy harvesting device), which may be reference signals. Figure 1 , Figure 2 and Figure 8 Examples of the corresponding devices described. After process flow 900, wireless device 905 can avoid collisions between the transmitted OOK signal and the reference signal. The following alternative examples can be implemented, some of which may be performed in a different order than described or not at all. In some cases, steps may include additional features not mentioned below, or other steps may be added. Although UE 115-e and wireless device 905 are shown as performing the operation of process flow 900, some aspects of some operations may also be performed by one or more other wireless devices.

[0136] In some examples, wireless device 905 and UE 115-e can implement a conflict management process in an A-IoT scenario. For example, at 910, wireless device 905 can transmit (e.g., output) and UE 115-e (which may be an A-IoT device or an energy harvesting device) can receive (e.g., acquire) control signaling indicating multiple time points (e.g., consecutive time points). The control signaling may indicate that a first subset of the multiple time points is one or more OOK time points and a second subset of the multiple time points is one or more reference signal time points. In some examples, the control signaling may be a single control message indicating one or more OOK time points and one or more reference signal time points. In some examples, the control signaling may include more than one control message. For example, wireless device 905 can transmit and UE 115-e can receive a first control message indicating multiple time points and a second control message indicating one or more reference signal time points. In such examples, UE 115-e may assume that the remaining time points among the multiple time points that are not reference signal time points are OOK time points.

[0137] At 915, during one or more reference signal timing periods, wireless device 905 can transmit and UE115-e can receive one or more reference signal signals.

[0138] At 920, during one or more OOK time slots, radio device 905 may transmit and UE 115-e may receive one or more OOK signals. In some examples, radio device 905 may suppress transmission during one or more OOK time slots based on the occurrence of two or more reference signal time slots within a defined time duration. The defined time duration may be a number of time slots and may be indicated via control signaling at 905.

[0139] At 925, the wireless device 905 can monitor response messages (e.g., backscatter response messages) from UE 115-e in response to one or more OOK signals, one or more reference signals, or both.

[0140] At 930, UE 115-e can transmit (e.g., output) and wireless device 905 can receive (e.g., acquire) a response message in response to one or more OOK signals, in response to one or more reference signals, or in response to both.

A general-purpose processor may be a microprocessor, but in alternatives, a processor may be any processor, controller, microcontroller, or state machine. A processor may also be implemented as a combination of computing devices (e.g., a combination of a DSP and a microprocessor, multiple microprocessors, one or more microprocessors cooperating with a DSP core, or any other such configuration). Any function or operation described herein that can be performed by a processor may be performed by multiple processors capable of performing the described function or operation individually or jointly.

[0240] The functions described herein can be implemented using hardware, software executed by a processor, firmware, or any combination thereof. When implemented using software executed by a processor, the functions can be stored as one or more instructions or code on a computer-readable medium or transmitted using one or more instructions or code on a computer-readable medium. Other examples and specific implementations are within the scope of this disclosure and the appended claims. For example, due to the nature of software, the functions described herein can be implemented using software executed by a processor, hardware, firmware, hardwiring, or any combination of these. Features implementing the functions can also be physically located in various locations, including various portions distributed such that the functions are implemented in different physical locations.

[0241] Computer-readable media includes both non-transitory computer storage media and communication media, encompassing any medium that facilitates the transfer of a computer program from one location to another. Non-transitory storage media can be any available medium accessible by a general-purpose or special-purpose computer.

[0242] As used herein, the word "or" in a list of items (e.g., a list of items accompanied by phrases such as "at least one of" or "one or more of") in the claims indicates an inclusive list, such that a list of at least one of, for example, A, B, or C means A or B or C or AB or AC or BC or ABC (i.e., A and B and C). Furthermore, as used herein, the phrase "based on" should not be construed as a reference to a closed set of conditions. For example, an example step described as "based on condition A" could be based on both condition A and condition B without departing from the scope of this disclosure. In other words, as used herein, the phrase "based on" should be interpreted in the same manner as the phrase "at least partially based on".

[0243] As used herein, including in claims, the article “a” preceding a noun is open-ended and is understood to refer to “at least one” or “one or more” of those nouns. Therefore, the terms “a,” “at least one,” “one or more,” and “at least one of one or more” are interchangeable. For example, where a claim enumerates “components” performing one or more functions, each of the individual functions may be performed by a single component or by any combination of multiple components. Thus, the term “component” having a characteristic or performing a function may refer to “at least one of one or more components” having a particular characteristic or performing a particular function. Subsequent references to a component introduced with the article “a” using the terms “the” or “the” may refer to any or all of the one or more components. For example, a component introduced with the article “a” may be understood to mean “one or more components,” and subsequent reference to “the component” in a claim may be understood to be equivalent to referring to “at least one of the one or more components.” Similarly, subsequent references to a component introduced with the terms “the” or “the” as “one or more components” may refer to any or all of the one or more components. For example, reference to "the one or more components" in the subsequent claims can be understood as equivalent to reference to "at least one of the one or more components".

[0244] The term "determine" encompasses a variety of actions, and therefore, "determine" can include calculation, computation, processing, derivation, investigation, searching (such as by searching in a table, database, or other data structure), ascertainment, etc. Furthermore, "determine" can include receiving (e.g., receiving information), accessing (e.g., accessing data stored in memory), etc. Moreover, "determine" can include parsing, obtaining, selecting, choosing, creating, and other similar actions.

[0245] In the accompanying drawings, similar components or features may have the same reference numerals. Furthermore, various components of the same type can be distinguished by adding a dash after the reference numeral and a second reference numeral to differentiate between similar components. If only the first reference numeral is used in the description, the description applies to any one of the similar components having the same first reference numeral, regardless of the second or other subsequent reference numerals.

[0246] The description herein, illustrated with reference to the accompanying drawings, describes an example configuration and does not represent all achievable examples or those within the scope of the claims. The term "example" as used herein means "serving as an example, instance, or illustration," not "preferred" or "advantageous over other examples." The detailed description includes specific details used to provide an understanding of the described techniques. However, these techniques can be practiced without these specific details. In some of the drawings, known structures and devices are shown in block diagram form to avoid obscuring the concept of the described examples.

[0247] The description herein is provided to enable those skilled in the art to implement or use this disclosure. Various modifications to this disclosure will be apparent to those skilled in the art, and the general principles defined herein may be applied to other variations without departing from the scope of this disclosure. Therefore, this disclosure is not limited to the examples and designs described herein, but should be granted the widest scope consistent with the principles and novel features disclosed herein.
