Technical Field

[0001] The following relates to wireless communication, including subchannel allocation for polarization decoding of ambient wireless devices. 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] Wireless communication in communication devices may include polar coding techniques. In some examples, communication devices implementing polar coding techniques may include encoder devices and decoder devices, which may be implemented in ambient wireless devices, network entities, and user-defined devices (UEs).

[0038] As different systems and applications for wireless technology evolve, ambient wireless devices are likely to become increasingly relevant. Applications may include asset management, logistics, warehousing, and manufacturing, which may include supporting ambient wireless devices. Such devices may include passive Internet of Things (IoT) devices, such as radio frequency identification (RFID) type sensors. Network entities and user equipment (UEs), as well as other wireless devices, may be required to interact with ambient wireless devices. For example, wireless devices may read and write information stored on ambient wireless devices and may provide power to them. In some examples, wireless devices may receive information transmitted by ambient wireless devices.

[0039] Environmental wireless devices have certain limitations, such as little or no energy storage. Communication with another wireless device (such as transmitting signals carrying information) requires resources or increases complexity, leading to higher power consumption. One such communication scheme could be polar decoding, which can increase the reliability of transmission. In a polar decoding scheme, the environmental wireless device may perform multiple steps to encode the message before transmission, which can be resource-intensive and complex. For example, an encoder device (such as an environmental wireless device) may perform polar decoding on a set of information bits. Polar encoding may include: ordering the information bits according to the reliability associated with a subchannel of the polar code sequence; reordering the information bits according to the associated bit index; and inputting the resulting reordered bits into the polar code. Such processes can be resource-intensive for environmental wireless devices, leading to limitations associated with performing polar decoding.

[0040] The techniques described herein provide a simplified polarization decoding process at an ambient wireless device. As part of polarization coding, the ambient wireless device (e.g., an encoder device) maps a set of information bits to the corresponding reliability of a subchannel (e.g., a channel) of the polarization code sequence and inputs the resulting mapped set of information bits into the polarization code. The output can be transmitted as a codeword to another wireless device (e.g., a decoder device). The wireless device can receive the codeword and perform polarization decoding. Polarization decoding may include inputting the codeword into a codeword decoding operation and outputting a decoded bit sequence. The decoded bit sequence can be ordered according to the mapped reliability of the subchannels of the polarization code sequence. The decoder device can demap or reorder the decoded bit sequence according to the bit index associated with each information bit in the set of information bits. Therefore, the wireless device, rather than the ambient wireless device, can perform reordering based on the bit index, resulting in reduced complexity and resource usage at the ambient wireless device.

[0041] The aspects of this disclosure are first described in the context of a wireless communication system. The aspects of this disclosure are further illustrated and described with reference to a wireless communication system, a polarization decoding diagram, and a process flowchart. The aspects of this disclosure are further illustrated and described with reference to apparatus diagrams, system diagrams, and flowcharts relating to sub-channel allocation for polarization decoding of an environmental wireless device.

[0042] Figure 1An example of a wireless communication system 100 supporting sub-channel allocation for polarization decoding of an ambient wireless device, according to one or more aspects of this disclosure, is shown. The wireless communication system 100 may include one or more network entities 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.

[0043] 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, among other designations. In some examples, network entity 105 and UE 115 may wirelessly communicate via one or more communication links 125 (e.g., radio frequency (RF) access links). For example, network entity 105 may support coverage area 110 (e.g., a geographical coverage area) within which UE 115 and network entity 105 may establish one or more communication links 125. Coverage area 110 may be an example of a geographical area within which network entity 105 and UE 115 may support the transmission of signals according to one or more radio access technologies (RATs).

[0044] 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 can be able to support various types of devices (such as, e.g., ...). Figure 1 It communicates with other UEs (115 or network entity 105) as shown.

[0045] As described herein, nodes of the wireless communication system 100 (which may be referred to as network nodes or wireless nodes) may be network entity 105 (e.g., any network entity described herein), UE 115 (e.g., any UE described herein), 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. Alternatively, a node may be network entity 105. Furthermore, a first node may be configured to communicate with a second or 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.

[0046] 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 one or more backhaul communication links 120 (e.g., according to S1, N2, N3, or other interface protocols). In some examples, network entities 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 links 120 (e.g., according to X2, Xn, or other interface protocols). In some examples, network entities 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. Backhaul communication link 120, midhaul communication link 162, or fronthaul communication link 168 may be or 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 can communicate with core network 130 via communication link 155.

[0047] One or more network entities in network entity 105 described herein 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, node B, eNodeB (eNB), next-generation node B or gigabit node B (any of which may be referred to as gNB), 5G NB, next-generation eNB (ng-eNB), home node B, home evolution node B, 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 105 (e.g., a single RAN node, such as base station 140).

[0048] 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 two or more network entities 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) 160, a distributed unit (DU) 165, a radio unit (RU) 170, a RAN intelligent controller (RIC) 175 (e.g., a near real-time RIC, a non-real-time RIC), a service management and orchestration (SMO) 180 system, or any combination thereof. 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 105 in a decomposed RAN architecture may be implemented as virtual units (e.g., virtual CU (VCU), virtual DU (VDU), virtual RU (VRU)).

[0049] 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, and 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 can connect to one or more DU 165 or RU 170, and one or more DU 165 or RU 170 can 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 each can be at least partially controlled by CU 160. Additionally or alternatively, a protocol stack functional split can be employed between DU 165 and RU 170, such that DU 165 can support one or more layers of the protocol stack, and RU 170 can support one or more different layers of the protocol stack. DU 165 can support one or more different cells (e.g., via one or more RU 170). 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) and CU user plane (CU-UP) functions. CU 160 can be connected to one or more DU 165 via midhaul communication link 162 (e.g., F1, F1-c, F1-u), and DU 165 can be connected to one or more 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 the corresponding network entities 105 communicating via such communication links.

[0050] In some wireless communication systems (e.g., wireless communication system 100), the infrastructure and spectrum resources for radio access may 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 105 (e.g., IAB node 104) may be partially controlled by each other. One or more IAB nodes 104 may be referred to as donor entities or IAB donors. One or more DU 165s or one or more RU 170s may be partially controlled by one or more CU 160s associated with donor network entity 105 (e.g., donor base station 140). One or more donor network entities 105 (e.g., IAB donors) may communicate with one or more additional network entities 105 (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 a DU 165 of a coupled IAB donor. The IAB-MT may include 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 a DU 165 that supports 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., one or more IAB nodes 104 or components of IAB node 104) may be configured to operate according to the techniques described herein.

[0051] For example, the access network (AN) or RAN may include communication between an access node (e.g., an IAB donor), IAB node 104, and one or more UEs 115. The IAB donor may facilitate connectivity between the core network 130 and the AN (e.g., via a wired or wireless connection to the core network 130). That is, an IAB donor may refer to a RAN node having a wired or wireless connection to the core network 130. The IAB donor may include a CU 160 and at least one DU 165 (e.g., and RU 170), where the CU 160 may communicate with the core network 130 via an interface (e.g., a backhaul link). The IAB donor and IAB node 104 may communicate via an F1 interface according to a protocol defining the signaling messages (e.g., the F1 AP protocol). Additionally or alternatively, the CU 160 may communicate with the core network via an interface (which may be part of a backhaul link) and may communicate with other CU 160s (e.g., CU 160 associated with an alternative IAB donor) via an Xn-C interface (which may be part of a backhaul link).

[0052] IAB node 104 may refer to a RAN node that provides IAB functionality (e.g., access for UE 115, radio self-backhaul capability, etc.). DU 165 may act as a distributed scheduling node toward child nodes associated with IAB node 104, and IAB-MT may act as a scheduled node toward a parent node associated with IAB node 104. That is, an IAB donor may be referred to as a parent node communicating with one or more child nodes (e.g., an IAB donor may relay UE transmissions through one or more other IAB nodes 104). Additionally or alternatively, depending on the AN's relay chain or configuration, IAB node 104 may also be referred to as a parent or child node of other IAB nodes 104. Therefore, the IAB-MT entity of IAB node 104 can provide a Uu interface for child IAB node 104 to receive signaling from parent IAB node 104, and the DU interface (e.g., DU 165) can provide a Uu interface for parent IAB node 104 to send signaling notifications to child IAB node 104 or UE 115.

[0053] For example, IAB node 104 may be referred to as a parent node supporting communication to child IAB nodes, or as a child IAB node associated with an IAB donor, or both. An IAB donor may include a CU 160 having a wired or wireless connection to core network 130 (e.g., backhaul communication link 120) and may act as a parent node of IAB node 104. For example, the IAB donor's DU 165 may relay transmissions to UE 115 via IAB node 104, or may signal transmissions directly to UE 115, or both. The IAB donor's CU 160 may signal the establishment of a communication link to IAB node 104 via an F1 interface, and IAB node 104 may schedule transmissions via DU 165 (e.g., transmissions relayed from the IAB donor to UE 115). That is, data may be relayed to and from IAB node 104 via signaling through the NR Uu interface of the MT to IAB node 104. Communication with IAB node 104 can be scheduled by DU 165 of the IAB donor, and communication with IAB node 104 can be scheduled by DU 165 of IAB node 104.

[0054] In the context of applying the techniques described herein to a decomposed RAN architecture, one or more components of the decomposed RAN architecture can be configured to support subchannel allocation for polarization decoding of environmental radio devices as 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., IAB node 104, DU 165, CU 160, RU 170, RIC 175, SMO 180).

[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 other UEs 115 that sometimes act as relays, network entities 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 one or more communication links 125 (e.g., access links) using resources associated with one or more carriers. The term "carrier" can refer to a set of RF spectrum resources having a physical layer structure defined 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 physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling coordinating carrier operation, user data, or other signaling. Wireless communication system 100 may support communication with UE 115 using carrier aggregation or multi-carrier operation. Depending on the carrier aggregation configuration, UE 115 may be configured with multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation may 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 refer to any part of the RAN’s network entity 105 (e.g., base station 140, CU160, DU 165, RU 170) communicating with another device (e.g., directly or via one or more other network entities 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, in which case 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 may 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, of which It can represent the supported subcarrier spacing, and This can represent the supported Discrete Fourier Transform (DFT) size. The time interval of the communication resources can be organized according to 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 certain 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 certain number of symbol periods (e.g., depending on the length of the cyclic prefix appended to each symbol period). In some wireless communication systems 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 can be defined by a set of symbol periods and can 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 can monitor or search for control regions to obtain control information based on one or more search space sets, and each search space set can 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 can 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 common search space set configured to transmit control information to multiple UEs 115, and a UE-specific search space set used to transmit control information to a specific UE 115.

[0063] In some examples, network entity 105 (e.g., base station 140, RU 170) may be mobile, and thus provide communication coverage to mobile coverage areas 110. In some examples, different coverage areas 110 associated with different technologies may overlap, but the different coverage areas 110 may be supported by the same network entity 105. In some other examples, overlapping coverage areas 110 associated with different technologies may be supported by different network entities 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 radio access technologies to provide coverage for various coverage areas 110.

[0064] Some UE 115s (such as MTC or IoT devices) can be 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 meters 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 115s 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 geographic event monitoring, queue management and tracking, remote security sensing, physical access control, and transaction-based commercial 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 or 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 prioritization of 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 UE 115s via device-to-device (D2D) communication link 135 (e.g., according to peer-to-peer (P2P), D2D, or sidelink protocols). In some examples, one or more UE 115s performing D2D communication in a group 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 UE 115s in such a 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, the group of UE 115s communicating via D2D communication may support a one-to-many (1:M) system, where each UE 115 transmits to each of the other UE 115s in the group. In some examples, network entity 105 may facilitate the scheduling of resources used for D2D communication. In other examples, D2D communication may be performed between UEs 115 without involving network entity 105.

[0067] In some systems, the D2D communication link 135 may be an example of a communication channel (such as a sidelink communication channel) between vehicles (e.g., UE 115). In some examples, vehicles may communicate using vehicle-to-vehicle (V2X) communication, vehicle-to-vehicle (V2V) communication, or some combination of these. Vehicles may signal information related to traffic conditions, signaling, weather, safety, emergencies, or any other information relevant to the V2X system. In some examples, vehicles in a V2X system may communicate with roadside infrastructure (such as roadside units), or communicate with the network via one or more network nodes (e.g., network entity 105, base station 140, RU 170) using vehicle-to-network (V2N) communication, or both.

[0068] Core network 130 provides user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. Core network 130 may be an evolved packet core (EPC) or a 5G core (5GC), and 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 delivered through user plane entities, which provide IP address allocation and other functions. User plane entities may 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.

[0069] Wireless communication system 100 can operate using one or more frequency bands in the range of 300 MHz to 300 GHz. Generally, the area from 300 MHz to 3 GHz is referred to as the Ultra High Frequency (UHF) band 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 waves in the High 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 100 km).

[0070] Wireless communication system 100 may utilize licensed and unlicensed RF spectrum bands. For example, wireless communication system 100 may use unlicensed frequency bands (such as the 5 GHz Industrial, Scientific, and Medical (ISM) band) to employ licensed assisted access (LAA), LTE unlicensed (LTE-U) radio access technology, or NR technology. When operating with unlicensed RF spectrum bands, 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 combined with component carriers operating with licensed frequency bands based on carrier aggregation configurations (e.g., LAA). Operation using unlicensed spectrum may include downlink transmission, uplink transmission, P2P transmission, or D2D transmission, etc.

[0071] 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.

[0072] 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).

[0073] UE 115, network entity 105, and other radio devices can communicate with ambient radio devices. Some communications may employ polar decoding, which can increase the reliability of transmission. In a polar decoding scheme, the ambient radio device may perform multiple steps to encode the message before transmission, which can be resource-intensive and complex. For example, an encoder device (such as the ambient radio device) may perform polar decoding on a set of information bits. Polar encoding may include: ordering the information bits according to the reliability associated with the subchannels of the polar code sequence; reordering the information bits according to the associated bit index; and inputting the resulting reordered bits into the polar code. Such processes can be resource-intensive for the ambient radio device, leading to limitations associated with performing polar decoding.

[0074] The techniques described herein provide a simplified polarization decoding process at an ambient wireless device. As part of polarization coding, the ambient wireless device (e.g., an encoder device) maps a set of information bits to the corresponding reliability of a subchannel (e.g., a channel) of the polarization code sequence and inputs the resulting mapped set of information bits into the polarization code. The output can be transmitted as a codeword to another wireless device (e.g., a decoder device, UE 115, network entity 105). The wireless device can receive the codeword and perform polarization decoding. Polarization decoding may include inputting the codeword into a codeword decoding operation and outputting a decoded bit sequence. The decoded bit sequence can be ordered according to the mapped reliability of the subchannels of the polarization code sequence. The decoder device can demap or reorder the decoded bit sequence according to the bit index associated with each information bit in the set of information bits. Therefore, the wireless device, rather than the ambient wireless device, can perform reordering based on the bit index, resulting in reduced complexity and resource usage at the ambient wireless device. Reference Figures 2 to 4 The technology is further described and illustrated.

[0075] Figure 2 An example of a wireless communication diagram 200 supporting sub-channel allocation for polarization decoding of an ambient wireless device is shown, according to one or more aspects of this disclosure. Wireless communication diagram 200 depicts communication between an ambient wireless device 210 and a wireless device 205, wherein the communication may include polarization coding information. For example, the ambient wireless device 210 may send or otherwise indicate polarization-coded codewords 220 to the wireless device 205.

[0076] Environmental wireless device 210 may be an environmental Internet of Things (IoT) wireless device, an encoder device, or an encoding device. Wireless device 205 may be a UE supporting environmental wireless device 210, or it may be another device such as a network entity. In some examples, wireless device 205 may be an environmental IoT wireless device, an environmental wireless device, or an encoder device. Communication between environmental wireless device 210 and wireless device 205 may be via communication link 215, which may be an uplink, a downlink, or another communication link. In some examples, environmental wireless device 210 may be an encoding device, and wireless device 205 may be a decoding device. In some examples, environmental wireless device 210 may be a decoding device, and wireless device 205 may be an encoding device. For example, the wireless device may encode and transmit polar-coded codeword 220.

[0077] Devices can convey polar-coded information by implementing a polar-coding scheme, which may include encoding and polar-decoding. For example, ambient wireless device 210 may transmit a polar-coded codeword 220 to wireless device 205 via communication link 215. To create the polar-coded codeword 220, ambient wireless device 210 may perform polar-coding operations on one or more information bits in a set of information bits. The information bits may be associated with a message for wireless device 205. Wireless device 205 may receive the polar-coded codeword 220 and perform a polar-decoding operation. As part of the decoding operation, wireless device 205 may reorder the information bits according to a reliability order.

[0078] Polar decoding can be used for channel decoding in many applications, such as NR. Polar decoding is a technique that protects data from errors that occur during transmission. In some examples, polar decoding can be performed based on various parameters, such as transmission parameters. A sequence of one or more bits (e.g., ...) ) can be interleaved to create another sequence for polarization decoding (e.g., In some examples, the bit sequence may be data to be transmitted to another device (such as wireless device 205). Polar decoding may be implemented via a polar decoding scheme that may include steps such as polar code encoding (e.g., polar coding), polar code decoding (e.g., polar decoding), and sub-channel allocation, as well as elements such as polar code sequences (e.g., polar sequences).

[0079] A polarization sequence can be one or more polarization sub-channels (e.g., channels). The polarization sequence can be used to encode a bit sequence, which can be one or more interleaved bits. Each bit of the information bit sequence can be associated with a bit index, and each sub-channel of the polarization sequence can correspond to a reliability. Sub-channel allocation can include assigning each bit of the bit information sequence to a sub-channel of the polarization sequence. The assignment can be based on the reliability of each sub-channel and the priority of each information bit. For example, information bits ordered according to bit indices can be mapped and reordered according to sub-channel assignment.

[0080] Polarization sequences can be derived from It means that among them Indicating targeting and Bit index before polarization decoding, where Indicates information bits. Polarization sequence. It is ordered in ascending order of reliability. ,in Indicates each sub-channel Reliability. For encoding to Any code block of bits, sequence It is a polarization sequence (e.g., a sub-channel). A subset of [a subset], everything else is the same, using polarization sequences. Polarization sequence The value is less than Sort by reliability in ascending order Sort. It can be represented as a polarization sequence The set of sub-channel indices in, where The length is , Information bits and One parity bit. (Used in sub-channel allocation).

[0081] In sub-channel allocation, express The most reliable information bit index in, and Each input information bit is mapped to In this type of mapping, Sequences can be derived from reliability Reorder in ascending order to the index The ascending order. That is, the transmitting device can reorder the mapped information bits, which are sorted according to the subchannel reliability, to be sorted according to the information bit index. The transmitting device (e.g., an encoding device) can continue with the polarization decoding scheme and create codewords. Creating codewords may include encoding (e.g., combining) the information bits with polar codes. The receiver (e.g., a decoding device) can receive and decode the codewords, which can generate the information bits sequentially according to the index order. Decoding the information bits sorted according to the information bit order may be simpler for the receiver because the receiver does not need to reorder them after decoding.

[0082] As various systems and applications for wireless technology evolve, ambient wireless device 210 may become increasingly relevant. Applications may include asset management, logistics, warehousing, and manufacturing, as well as supporting passive IoT devices, such as RFID-type sensors. Passive IoT devices may be referred to as ambient wireless devices (e.g., ambient wireless device 210) or ambient IoT devices. Network entities, UEs, and other devices may be required to interact with ambient wireless device 210. For example, wireless device 205 (such as network entities and UEs) may read and write information stored on ambient wireless device 210. Wireless device 205 may provide power to ambient wireless device 210. Signals carrying information may be reflected back to the wireless device, and the wireless device may read the signals reflected by ambient wireless device 210 to decode the information transmitted by ambient wireless device 210.

[0083] Environmental wireless device 210 has certain limitations, such as little or no energy storage. Energy harvesting from the environment may be limited. For uplink communication or communication from environmental wireless device 210 to another wireless device 205, reducing power consumption at environmental wireless device 210 may be advantageous. Receiving devices (such as UEs or network entities) or wireless device 205 may not experience the same limitations (e.g., storage capacity). Implementing various parts of the polarization decoding scheme at environmental wireless device 210 may add complexity, resulting in more power consumption. For example, determining subchannel allocation (such as mapping subchannels to information bits) requires utilizing... The complexity can be categorized, or a bitmap of length 𝑁 with complexity 𝑂(𝑁). Techniques and methods for reducing complexity at the environmental wireless device 210 and thus reducing power consumption (especially when related to polarization decoding) may be advantageous.

[0084] The techniques described herein provide simplified subchannel allocation for polarization decoding of ambient wireless device 210. Such techniques reduce complexity at ambient wireless device 210 and thus reduce power consumption. Simplified subchannel allocation can be applied to the uplink, where the uplink can extend from ambient wireless device 210 to wireless device 205. The simplified subchannel allocation may include reordering information bits according to bit indices at the decoder device. That is, reordering that may have previously been performed at ambient wireless device 210 after mapping information bits to subchannels can be removed from ambient wireless device 210 and instead performed at wireless device 205. References Figure 3 and Figure 4 The technology is described further.

[0085] Reordering operations in the mobile subchannel allocation process may involve operational changes, including code modifications. For example, moving the reordering step to wireless device 205 can result in reduced power consumption in the subchannel allocation process during polar coding, leading to a more favorable process for the energy constraints of the ambient wireless device 210. Additionally, such methods support changes to the number of thresholds in the polar decoding process (e.g., minimal changes) without altering other processes.

[0086] Figure 3 An example of a polarization decoding diagram 300 supporting sub-channel allocation for polarization decoding of an ambient wireless device is shown, according to one or more aspects of this disclosure. Polarization decoding diagram 300 describes a polarization decoding scheme for polarization decoding, including polarization coding 305 (e.g., encoding, polar code encoding) and polarization decoding 370 (e.g., decoding, polar code decoding).

[0087] Polar coding 305 can be performed by a device such as an environmental wireless device (e.g., an environmental IoT device) or an encoding device. As part of polar coding 305, the encoding device may input bit sequence 310 into polar code 320. In some examples, bit sequence 310 may include one or more freeze bits 325. Inputting bit sequence 310 (e.g., input 315) into polar code 320 may create or output codeword 330. The encoder device may send 335 to the decoder device or otherwise output or communicate codeword 330 for polar decoding 370. Polar coding 305 may include or may not include all the elements described herein, and may include additional elements. For example, interleaving may be included as part of polar coding 305, or input 315 may not be included as part of polar coding 305.

[0088] Polar decoding 370 can be performed by a device, such as a decoder device, a UE configured to support an environment of wireless devices, a network entity, or another wireless device. The decoder device can receive codeword 330 and perform polar decoding 370. Polar decoding 370 may include inputting codeword 330 into codeword decoding 340. Codeword decoding 340 may output 345 (e.g., creating, generating) a decoded bit sequence 350. The decoder device may reorder 360 of the decoded bit sequence 350 to create a reordered bit sequence 365. Polar encoding 305 may include or may not include all the elements described herein, and may include additional elements.

[0089] By performing reordering 360 as part of polarization decoding 370, complexity and power requirements can be reduced at the encoder device performing polarization coding 305. By not performing the reordering step (e.g., reordering 360) as part of polarization coding 305, the encoder device (e.g., an ambient wireless device) can have simplified polarization coding 305. For example, an ambient wireless device can have simplified subchannel allocation.

[0090] Bit sequence 310 can be one or more information bits, such as bit 1, bit 2, bit 3, ..., bit n. Bit sequence 310 may include one or more freeze bits 325, which may not be assigned and may increase reliability. Freeze bits may also not be reordered. Information bits may be associated with messages sent to encoder devices. Each bit in bit sequence 310 may be associated with a bit index and ordered according to the bit index order. Bit 1 may be the first bit, bit 2 may be the second bit, and so on. Bit n may indicate the nth bit, such that any number of bits can exist.

[0091] Polar coding may include mapping information bits to one or more subchannels (e.g., channels) of a polar code sequence. Each subchannel may be associated with a reliability. Information bits may be mapped to a subchannel (e.g., associated with or assigned to that subchannel). Mapping may include associating information bits with subchannels and ordering the information bits according to the subchannels. Subchannels may be ordered according to increasing reliability. By ordering the information bits according to the assigned subchannels, the information bits may also be ordered according to the reliability of the subchannels. After mapping, the information bits may no longer be in bit index order. For example, the information bits may no longer be ordered as bit 1, bit 2, bit 3, ... bit n. Instead, the bit sequence 310 and therefore bits 3, bit n, bit 1, and bit 2 may be ordered according to the reliability of the subchannels. Without a reference freeze bit, the order may be bit 3, bit n (e.g., any number of bits), bit 1, bit 2. In some examples, the reliability may be increasing reliability.

[0092] Each bit in bit sequence 310 can be mapped to a sub-channel (e.g., a polar channel) of the polar code sequence. Each sub-channel may have a corresponding reliability, but the sub-channels may not be ranked based on reliability. That is, the first sub-channel may not be the most reliable, the second sub-channel may not be the second most reliable, and so on.

[0093] However, the bits of bit sequence 310 can be mapped to a subchannel based on the reliability of the subchannel. Since bit sequence 310 is mapped according to the reliability of the subchannel, the encoder device can input bit sequence 310 into polar code 320 (315) and transmit the resulting codeword 330 (335). The decoder device can receive codeword 330, perform codeword decoding (340), and output the decoded bit sequence 350 (345). Similar to bit sequence 310, the decoded bit sequence 350 can be sorted according to the reliability of the subchannel. For example, the information bits of the decoded bit sequence 350 can be sorted as: bit 3, bit n, bit 1, bit 2. The decoder device can then reorder the decoded bit sequence 350 (360) to output a reordered bit sequence (365).

[0094] Reordering may include demapping each information bit from each of the corresponding sub-channels of the decoded bit sequence 350. The decoder device may reorder the decoded bit sequence 350 according to bit indices, as in the reordered bit sequence 365. For example, the information bits may be in the following order: bit 1, bit 2, bit 3, ..., bit n. Such reordering at the polar decoder, rather than at the polar encoder, reduces the complexity at the polar encoder. This reduces the complexity during the polar coding process, which may be advantageous when the polar encoder is located at an ambient wireless device.

Figure 2 An example of the described wireless device 205.

[0096] In the description of process flowchart 400, the operations between encoder device 405 and decoder device 410 may be performed in different orders or at different times. Some operations may also be excluded from process flowchart 400, or other operations may be added. Although encoder device 405 and decoder device 410 are shown performing the operations of process flowchart 400, some aspects of some operations may also be performed by one or more other wireless devices.

Decoder device 410 may be an example of a UE capable of supporting ambient IoT wireless devices, network entities, wireless devices, or another device capable of polarization decoding.

[0097] At 415, encoder device 405 may perform polarization coding on a set of information bits associated with a message sent by encoder device 405, wherein the set of information bits is ordered according to bit index order. The bit index order allows each bit in the set of information bits to be ordered in ascending consecutive order according to its corresponding bit index.

[0098] Performing polar coding operations may include mapping one or more information bits from a set of information bits to one or more corresponding polar channels (e.g., sub-channels) of the polar code sequence according to a reliability order. Mapping one or more information bits may include mapping each of the one or more information bits to a corresponding polar channel in the one or more corresponding polar channels based on the corresponding reliability of the corresponding polar channels. The reliability order may be a sorting based on ascending reliability.

[0099] Performing polar coding operations may include performing polar coding operations according to a polar decoding scheme, wherein the polar decoding scheme indicates one or more polar channels, a polar code sequence, a reliability order of the polar code sequence, one or more transmission parameters, a polar code sequence length, one or more coding operations associated with one or more polar channels, or a combination thereof.

[0100] Performing a polar coding operation may include outputting one or more mapped information bits in a reliability order according to the polar code sequence, such that the mapped one or more information bits are ordered according to the corresponding reliability of one or more polar channels of the polar code sequence.

[0101] At 420, encoder device 405 may send a codeword in a message, the codeword comprising one or more mapped information bits from a set of information bits encoded according to polarization coding operations and ordered according to reliability order. Encoder device 405 may send a message to decoder device 410, which may be a wireless device, user equipment supporting environmental IoT devices, or a network entity. Encoder device 405 may be an environmental wireless device or an environmental IoT wireless device.

[0102] At 425, decoder device 410 can perform a polarization decoding operation on the codeword. Performing the polarization decoding operation may include decoding a set of encoded information bits using one or more corresponding polarization channels of the polarization code sequence according to the reliability order of the polarization code sequence to obtain one or more decoded information bits. Decoder device 410 can decode the set of encoded information bits according to the reliability order of the polarization code sequence, wherein the reliability order is the ascending reliability order of the corresponding one or more polarization channels.

[0103] The polarization decoding operation may also include inputting a set of encoded information bits ordered according to the reliability of the polarization code sequence, such that, according to the polarization decoding scheme, the set of encoded information bits is ordered according to the corresponding reliability of one or more polarization channels.

[0104] Polarization decoding operations may include demapping each encoded information bit in the set of encoded information bits from the corresponding polarization channel in one or more corresponding polarization channels.

[0105] At 430, the decoder device can (as part of a polarization decoding operation) reorder one or more decoded information bits according to the bit index order. The bit index order allows each bit to be ordered in ascending consecutive order according to its corresponding bit index.

[0202] It should be noted that the methods described herein describe possible specific implementations, and the operations and steps can be rearranged or otherwise modified, and other specific implementations are also possible. Furthermore, aspects from two or more of these methods can be combined.

[0203] While aspects of LTE, LTE-A, LTE-A Pro, or NR systems may be described for illustrative purposes, and the terms LTE, LTE-A, LTE-A Pro, or NR may be used in most of the description, the techniques described herein are also applicable to networks other than LTE, LTE-A, LTE-A Pro, or NR networks. For example, the techniques described are applicable to a variety of other wireless communication systems, such as Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20, Flash-OFDM, and other systems and radio technologies not explicitly mentioned herein.

[0204] The information and signals described herein can be represented using any of a variety of different techniques and methods. For example, data, instructions, commands, information, signals, bits, symbols, and chips mentioned throughout the description can be represented by voltage, current, electromagnetic waves, magnetic fields or magnetic particles, light fields or optical particles, or any combination thereof.

[0205] The various exemplary blocks and components described herein can be implemented or performed using a general-purpose processor, DSP, ASIC, CPU, GPU, NPU, FPGA, or other programmable logic device, discrete gate or transistor logic unit, discrete hardware component, or any combination thereof designed to perform the functions described herein. A general-purpose processor may be a microprocessor, but in alternative embodiments, 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 working in conjunction 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.

[0206] The functionality described herein can be implemented using hardware, software executed by a processor, or any combination thereof. Software should be broadly interpreted as instructions, instruction sets, code, code segments, program code, programs, subroutines, software modules, applications, software applications, software packages, routines, subroutines, objects, executables, threads of execution, procedures, or functions, whether referred to as software, firmware, middleware, microcode, hardware description languages, or other terms. When implemented using software executed by a processor, the functionality 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 functionality described herein can be implemented using software executed by a processor, firmware, hardwired, or any combination thereof. Features implementing the functionality can also be physically located in various locations, including portions distributed such that the functionality is implemented at different physical locations.

[0207] 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. By way of example, and not limitation, non-transitory computer-readable media may include RAM, ROM, electrically erasable programmable ROM (EEPROM), flash memory, compressed optical disc (CD) ROM or other optical disc storage, disk storage or other magnetic storage devices, or any other non-transitory medium that can be used to carry or store desired program code components in the form of instructions or data structures, and accessible by a general-purpose or special-purpose computer or a general-purpose or special-purpose processor. Furthermore, any connection is appropriately referred to as computer-readable media. For example, if software is transmitted from a website, server, or other remote source using coaxial cable, fiber optic cable, twisted pair, digital subscriber line (DSL), or wireless technologies such as infrared, radio, and microwave, then coaxial cable, fiber optic cable, twisted pair, DSL, or wireless technologies such as infrared, radio, and microwave are included within the definition of computer-readable media. As used herein, disks and optical discs include CDs, laser discs, optical discs, digital multifunction discs (DVDs), floppy disks, and Blu-ray discs. Disks can magnetically reproduce data, and optical discs can optically reproduce data using lasers. Combinations of the above are also included within the scope of computer-readable media. Any function or operation described herein that can be performed by memory can be performed by multiple memories capable of performing the described function or operation individually or jointly.

[0208] 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".

[0209] 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” can refer to any or all of the one or more components. For example, a component introduced with the article “a” can be understood to mean “one or more components,” and subsequent reference to “the component” in a claim can be understood as 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” can 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".

[0210] The term "determine" encompasses a variety of actions, and therefore, "determine" can include calculation, computation, processing, derivation, investigation, lookup (such as by searching in a table, database, or other data structure), identification, and similar actions. Furthermore, "determine" can include receiving (e.g., receiving information), accessing (e.g., accessing data stored in memory), etc. Moreover, "determine" can include parsing, acquiring, selecting, choosing, building, and other similar actions.

[0211] 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 them. If only the first reference numeral is used in the description, the description can be applied to any of the similar components having the same first reference numeral, regardless of the second or other subsequent reference numerals.

[0212] The description herein, illustrated with reference to the accompanying drawings, describes an example configuration and does not represent all implementable or within the scope of the claims. The term "example" as used herein means "serving as an example, instance, or illustration," and 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 instances, known structures and devices are shown in block diagram form to avoid obscuring the concept of the described examples.

[0213] 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.
