[0089] A UE and one or more base stations in a wireless communication system (such as an NR system) may support a broadcast relay method. The wireless communication system may include a broadcast transmitter that sends one or more broadcast signals. In some examples, the broadcast transmitter may be referred to as an NR broadcast transmitter. In one example, the broadcast signal may include one or more multi-resolution messages. For example, the broadcast signal may include multiple messages, each associated with a resolution level. In some instances, the UE may receive one or more broadcast transmissions (such as a broadcast signal including one or more multi-resolution messages) from the broadcast transmitter. In some cases, the UE may not be able to successfully decode the broadcast signal. For example, if the UE is located at a position that exceeds a threshold distance from the broadcast transmitter, the UE may not be able to decode one or more multi-resolution messages. In one instance, the UE may be able to decode low-resolution messages (e.g., low-resolution broadcast content) in one or more multi-resolution messages. In some embodiments, the wireless communication system may support improved broadcast procedures in NR.

[0090] According to one or more aspects of the present disclosure, a UE may be connected to a nearby base station when receiving a broadcast signal from a broadcast transmitter, and may determine whether the base station includes the ability to relay a broadcast signal. In some embodiments, the UE may receive a broadcast signal from a broadcast transmitter. After receiving the broadcast signal, the UE may attempt to decode the broadcast signal. For example, the UE may decode at least one of the one or more multi-resolution messages included in the broadcast signal. In one example, the UE may determine that the data rate associated with the broadcast signal is less than a threshold based on decoding at least one of the one or more multi-resolution messages. If the UE determines that the decoded message includes low data content, the UE may send a signal to query the broadcast reception capability of a nearby base station. For example, the UE may determine that the UE is connected to a base station. After identifying the connected base station, the UE may query the base station to determine whether the base station has the ability to receive a broadcast signal. The base station may receive the query signal and may determine whether the base station includes the ability to receive a broadcast transmission from a broadcast transmitter. If the base station determines that the base station has the ability to receive a broadcast signal, the base station may indicate the broadcast reception capability to the UE. In some embodiments, after receiving the indication from the base station, the UE may determine the link quality between the base station and the UE. In some cases, if the link quality exceeds a threshold, the UE may select a base station for relaying a broadcast signal.

[0091] According to some aspects of the present disclosure, after selecting a base station for receiving a relay signal, the UE may receive a configuration signal indicating the transmission mode of the base station. For example, the UE may receive a radio resource control signal from the selected base station. In some embodiments, a configuration signal may be used to indicate to the UE the start time of the base station transmission mode. Alternatively, the start time of transmitting the relay signal may be flexible. In such cases, the UE may be configured to monitor multiple instances of receiving a relay signal from the base station. In some cases, the relay signal is a relay of a broadcast signal sent from a broadcast transmitter. The base station may receive a broadcast signal from a broadcast transmitter, and may send a broadcast signal to the UE according to the transmission mode of the base station.

[0092] Aspects of the present disclosure are initially described in the context of a wireless communication system. Aspects of the present disclosure are further illustrated and described with reference to apparatus diagrams, system diagrams, and flow charts related to broadcast relay methods in NR.

[0093] Figure 1An example of a wireless communication system 100 supporting a broadcast relay method in NR according to one or more aspects of the present disclosure is shown. The wireless communication system 100 includes a base station 105 (e.g., a gNodeB (gNB) and / or a radio head (RH)), a UE 115, and a core network 130. In some examples, the wireless communication system 100 can be an LTE network, an LTE-A network, an LTE-APro network, or an NR network. In some cases, the wireless communication system 100 can support enhanced broadband communication, ultra-reliable (e.g., mission-critical) communication, low-latency communication, or communication with low-cost and low-complexity devices.

[0094] The base station 105 may communicate wirelessly with the UE 115 via one or more base station antennas. The base station 105 described herein may include or may be referred to by those skilled in the art as a base station transceiver, a radio base station, an access point, a radio transceiver, a NodeB, an eNodeB (eNB), a next generation NodeB or a giga-NodeB (any of which may be referred to as a gNB), a home NodeB, a home eNodeB, or some other suitable term. The wireless communication system 100 may include different types of base stations 105 (e.g., macro cell base stations or small cell base stations). The UE 115 described herein may be able to communicate with various types of base stations 105 and network devices, including macro eNBs, small cell eNBs, gNBs, and relay base stations, among others.

[0095] Each base station 105 may be associated with a particular geographic coverage area 110 in which communications with various UEs 115 are supported. Each base station 105 may provide communications coverage for a respective geographic coverage area 110 via a communications link 125, and the communications link 125 between the base station 105 and the UE 115 may utilize one or more carriers. The communications link 125 shown in the wireless communication system 100 may include an uplink transmission from the UE 115 to the base station 105, or a downlink transmission from the base station 105 to the UE 115. Downlink transmissions may also be referred to as forward link transmissions, and uplink transmissions may also be referred to as reverse link transmissions.

[0096] The geographic coverage area 110 of the base station 105 can be divided into sectors that constitute a portion of the geographic coverage area 110, and each sector can be associated with a cell. For example, each base station 105 can provide communication coverage for a macro cell, a small cell, a hotspot, or other type of cell, or various combinations thereof. In some examples, the base station 105 can be mobile and thus provide communication coverage for a mobile geographic coverage area 110. In some examples, different geographic coverage areas 110 associated with different technologies can overlap, and the same base station 105 or different base stations 105 can support overlapping geographic coverage areas 110 associated with different technologies. The wireless communication system 100 may include, for example, a heterogeneous LTE / LTE-A / LTE-A Pro or NR network, in which different types of base stations 105 provide coverage for various geographic coverage areas 110.

[0097] The term "cell" refers to a logical communication entity used for communication with a base station 105 (e.g., via a carrier), and may be associated with an identifier (e.g., a physical cell identifier (PCID), a virtual cell identifier (VCID)) used to distinguish adjacent cells operating via the same or different carriers. In some examples, a carrier may support multiple cells, and different cells may be configured according to different protocol types that may provide access to different types of devices (e.g., machine type communication (MTC), narrowband Internet of Things (NB-IoT), enhanced mobile broadband (eMBB), or other protocol types). In some cases, the term "cell" may refer to a portion (e.g., a sector) of a geographic coverage area 110 on which the logical entity operates.

[0098] UE 115 may be dispersed throughout the wireless communication system 100, and each UE 115 may be fixed or mobile. UE 115 may also be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, or some other suitable term, where "device" may also be referred to as a unit, a station, a terminal, or a client. UE 115 may also be a personal electronic device, such as a cellular phone, a personal digital assistant (PDA), a tablet computer, a laptop computer, or a personal computer. In some examples, UE 115 may also refer to a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or an MTC device, etc., and the UE may be implemented in various articles such as electrical appliances, vehicles, meters, etc.

[0099] Some UEs 115, such as MTC or IoT devices, may be low-cost or low-complexity devices and may provide automated communication between machines (e.g., via machine-to-machine (M2M) communication). M2M communication or MTC may refer to data communication technology that allows devices to communicate with each other or with a base station 105 without human intervention. In some examples, M2M communication or MTC may include communication from devices that integrate sensors or meters to measure or capture information and relay the information to a central server or application that may utilize the information or present the information to humans interacting with the program or application. Some UEs 115 may be designed to collect information or implement automated behavior of machines. 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 business billing.

[0100] Some UEs 115 may be configured to employ a reduced power consumption mode of operation, such as half-duplex communication (e.g., a mode that supports one-way communication via transmission or reception but not simultaneous transmission and reception). In some examples, half-duplex communication may be performed at a reduced peak rate. Other power saving techniques for UE 115 include entering a power saving "deep sleep" mode when not engaged in active communication, or operating over a limited bandwidth (e.g., in accordance with narrowband communication). In some cases, UE 115 may be designed to support critical functions (e.g., mission-critical functions), and the wireless communication system 100 may be configured to provide ultra-reliable communication for these functions.

[0101] In some cases, UE 115 may also be able to communicate directly with other UE 115 (e.g., using a peer-to-peer (P2P) or device-to-device (D2D) protocol). One or more of a group of UEs 115 utilizing D2D communication may be within the geographic coverage area 110 of the base station 105. Other UEs 115 in the group may be outside the geographic coverage area 110 of the base station 105 or unable to receive transmissions from the base station 105. In some cases, multiple groups of UEs 115 communicating via D2D communication may utilize a one-to-many (1:M) system, in which each UE 115 transmits to each other UE 115 in the group. In some cases, the base station 105 facilitates the scheduling of resources for D2D communication. In other cases, D2D communication is performed between UEs 115 without the involvement of the base station 105.

[0102] The base stations 105 can communicate with the core network 130 and each other. For example, the base stations 105 can interface with the core network 130 via a backhaul link 132 (e.g., via S1, N2, N3, or other interfaces). The base stations 105 can communicate with each other directly (e.g., directly between the base stations 105) or indirectly (e.g., via the core network 130) via a backhaul link 134 (e.g., via X2, Xn, or other interfaces). The UE 115 can communicate with the core network 130 via a communication link 135.

[0103] The core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network 130 may be an evolved packet core (EPC), which may include at least one mobility management entity (MME), at least one serving gateway (S-GW), and at least one packet data network (PDN) gateway (P-GW). The MME may manage non-access stratum (e.g., control plane) functions such as mobility, authentication, and bearer management for UE 115 served by a base station 105 associated with the EPC. User IP packets may be delivered through the S-GW, which itself may be connected to the P-GW. The P-GW may provide IP address allocation and other functions. The P-GW may be connected to a network operator IP service. Operator IP services may include access to the Internet, an intranet, an IP multimedia subsystem (IMS), or a packet switched (PS) streaming service.

[0104] At least some network devices, such as base stations 105, may include subcomponents, such as access network entities, which may be examples of access node controllers (ANCs). Each access network entity may communicate with UE 115 through multiple other access network transmission entities, which may be referred to as radio heads, smart radio heads, or transmit / receive points (TRPs). In some configurations, the various functions of each access network entity or base station 105 may be distributed across various network devices (e.g., radio heads and access network controllers) or merged into a single network device (e.g., base station 105).

[0105] The wireless communication system 100 can operate using one or more frequency bands that can be in the range of 300 megahertz (MHz) to 300 gigahertz (GHz). Because the length of the wavelength ranges from about one decimeter to one meter, the region of 300MHz to 3GHz can be referred to as the ultra-high frequency (UHF) region or decimeter band. Buildings and environmental features may block or redirect UHF waves. However, the waves can penetrate the structure sufficiently so that the macrocell provides services to the UE 115 located indoors. Compared with the transmission of smaller frequencies and longer waves using the high frequency (HF) or very high frequency (VHF) portion of the spectrum below 300MHz, the transmission of UHF waves can be associated with smaller antennas and shorter ranges (e.g., less than 100km).

[0106] The wireless communication system 100 may also operate in the Super High Frequency (SHF) region using a frequency band from 3 GHz to 30 GHz, also known as the centimeter band. The SHF region includes bands such as the 5 GHz Industrial, Scientific, and Medical (ISM) band, which may be used opportunistically by devices that may be able to tolerate interference from other users.

[0107] The wireless communication system 100 may also operate in the extremely high frequency (EHF) region of the spectrum also referred to as the millimeter band (e.g., from 30 GHz to 300 GHz). In some examples, the wireless communication system 100 may support millimeter wave (mmW) communications between the UE 115 and the base station 105, and the EHF antennas of the corresponding devices may be smaller and more closely spaced than the UHF antennas. In some cases, this may facilitate the use of antenna arrays within the UE 115. However, the propagation of EHF transmissions may be affected by greater atmospheric attenuation and shorter distances than SHF or UHF transmissions. The technology disclosed herein may be employed across transmissions using one or more different frequency regions, and the designated use of bands across these frequency regions may vary from country to country or regulatory agency.

[0108] The electromagnetic spectrum is typically subdivided into various classes, bands, channels, etc. based on frequency / wavelength. In 5G NR, the two initial operating bands have been identified as FR1 (410 MHz to 7.125 GHz) and FR2 (24.25 GHz to 52.6 GHz). The frequencies between FR1 and FR2 are typically referred to as mid-band frequencies. Although a portion of FR1 is greater than 6 GHz, FR1 is typically (interchangeably) referred to as the "Sub-6 GHz" band in various literature and articles. Sometimes a similar naming problem occurs with FR2, which is typically (interchangeably) referred to as the "millimeter wave" band in literature and articles, although it is different from the extremely high frequency (EHF) band (30 GHz to 300 GHz), which is identified as the "millimeter wave" band by the International Telecommunication Union (ITU).

[0109] In view of the above, unless otherwise specifically stated, it should be understood that the term "sub-6 GHz" and the like when used herein can broadly represent frequencies that can be less than 6 GHz, can be within FR1, or can include mid-band frequencies. In addition, unless otherwise specifically stated, it should be understood that the term "millimeter wave" and the like when used herein can broadly represent frequencies that can include mid-band frequencies, can be within FR2, or can be within the EHF band.

[0110] In some cases, the wireless communication system 100 can utilize both licensed radio spectrum bands and unlicensed radio spectrum bands. For example, the wireless communication system 100 can adopt licensed assisted access (LAA), unlicensed LTE (LTE-U) radio access technology, or NR technology in unlicensed bands such as the 5GHz ISM band. When operating in an unlicensed radio frequency spectrum band, wireless devices such as base stations 105 and UE 115 can adopt a listen-before-talk (LBT) procedure to ensure that the channel is idle before sending data. In some cases, operations in unlicensed bands can be based on a combination of carrier aggregation configurations and component carriers operating in licensed bands (e.g., LAA). Operations in unlicensed spectrum can include downlink transmissions, uplink transmissions, peer-to-peer transmissions, or a combination of these. Duplexing in unlicensed spectrum can be based on frequency division duplexing (FDD), time division duplexing (TDD), or a combination of both.

[0111] In some examples, the base station 105 or the UE 115 may be equipped with multiple antennas, which may be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communications, or beamforming. For example, the wireless communication system 100 may use a transmission scheme between a transmitting device (e.g., a base station 105) and a receiving device (e.g., a UE 115), wherein the transmitting device is equipped with multiple antennas and the receiving device is equipped with one or more antennas. MIMO communications may employ multipath signal propagation to improve spectral efficiency by transmitting or receiving multiple signals via different spatial layers, which may be referred to as spatial multiplexing. Multiple signals may be transmitted, for example, by a transmitting device via different antennas or different combinations of antennas. Similarly, multiple signals may be received by a receiving device via different antennas or different combinations of antennas. Each of the multiple signals may be referred to as a separate spatial stream and may carry bits associated with the same data stream (e.g., the same codeword) or different data streams. Different spatial layers may be associated with different antenna ports for channel measurement and reporting. MIMO technology includes single-user MIMO (SU-MIMO) that transmits multiple spatial layers to the same receiving device and multi-user MIMO (MU-MIMO) that transmits multiple spatial layers to multiple devices.

[0112] Beamforming (which may also be referred to as spatial filtering, directional transmission, or directional reception) is a signal processing technique that can be used in a transmitting device or a receiving device (e.g., a base station 105 or a UE 115) to shape or steer an antenna beam (e.g., a transmit beam or a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming can be achieved by combining signals communicated via antenna elements of an antenna array so that signals propagating in a particular orientation relative to the antenna array experience constructive interference, while other signals experience destructive interference. Adjustments to signals communicated via antenna elements can include the transmitting device or the receiving device applying certain amplitude and phase offsets to signals carried via each of the antenna elements associated with the device. The adjustments associated with each of the antenna elements can be defined by a set of beamforming weights associated with a particular orientation (e.g., relative to the antenna array of the transmitting device or the receiving device, or relative to some other orientation).

[0113] In one example, the base station 105 may use multiple antennas or antenna arrays to perform beamforming operations for directional communication with the UE 115. For example, some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be sent multiple times by the base station 105 in different directions, which may include signals sent according to different beamforming weight sets associated with different transmission directions. The transmissions in different beam directions may be used to identify (e.g., by the base station 105 or a receiving device such as the UE 115) the beam direction for subsequent transmission and / or reception by the base station 105.

[0114] The base station 105 may transmit some signals, such as data signals associated with a particular receiving device, in a single beam direction (e.g., a direction associated with a receiving device such as the UE 115). In some examples, the beam direction associated with transmission along the single beam direction may be determined based at least in part on signals transmitted in different beam directions. For example, the UE 115 may receive one or more of the signals transmitted by the base station 105 in different directions, and the UE 115 may report an indication of the signals it received to the base station 105 at the highest signal quality or another acceptable signal quality. Although these techniques are described with reference to signals transmitted by the base station 105 in one or more directions, the UE 115 may employ similar techniques to transmit signals multiple times in different directions (e.g., to identify a beam direction for subsequent transmission or reception by the UE 115) or to transmit signals in a single direction (e.g., to transmit data to a receiving device).

[0115] A receiving device (e.g., a UE 115, which may be an example of a mmW receiving device) may try multiple receive beams when receiving various signals such as synchronization signals, reference signals, beam selection signals, or other control signals from a base station 105. For example, a receiving device may try multiple receive directions by receiving via different antenna subarrays, processing received signals according to different antenna subarrays, receiving according to different receive beamforming weighting groups applied to signals received in multiple antenna elements of an antenna array, or processing received signals according to different receive beamforming weighting groups applied to signals received in multiple antenna elements of an antenna array, any of which may be referred to as "listening" according to different receive beams or receive directions. In some examples, a receiving device may use a single receive beam to receive along a single beam direction (e.g., when receiving a data signal). A single receive beam may be aligned in a beam direction determined at least in part based on listening according to different receive beam directions (e.g., a beam direction determined to have the highest signal strength, the highest signal-to-noise ratio, or at least in part based on otherwise acceptable signal quality based on listening according to multiple beam directions).

[0116] In some cases, the antennas of a base station 105 or a UE 115 may be located within one or more antenna arrays that may support MIMO operations or may transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located in an antenna assembly such as an antenna tower. In some cases, the antennas or antenna arrays associated with a base station 105 may be located in different geographic locations. A base station 105 may have an antenna array with rows and columns of multiple antenna ports that the base station 105 may use to support beamforming for communications with a UE 115. Likewise, a UE 115 may have one or more antenna arrays that may support various MIMO or beamforming operations.

[0117] In some cases, the wireless communication system 100 can be a packet-based network that operates according to a layered protocol stack. In the user plane, the communication on the bearer or packet data convergence protocol (PDCP) layer can be IP-based. The radio link control (RLC) layer can perform packet segmentation and reorganization to communicate through logical channels. The medium access control (MAC) layer can perform priority processing and multiplex logical channels into transport channels. The MAC layer can also use hybrid automatic repeat request (HARQ) to provide retransmission in the MAC layer to improve link efficiency. In the control plane, the radio resource control (RRC) protocol layer can provide the establishment, configuration and maintenance of the RRC connection between the UE 115 and the base station 105 or the core network 130 that supports the radio bearer for user plane data. In the physical layer, the transport channel can be mapped to the physical channel.

[0118] In some cases, UE 115 and base station 105 can support retransmission of data to increase the possibility of data being successfully received. HARQ feedback is a technique to increase the possibility of correctly receiving data through communication link 125. HARQ can include a combination of error detection (e.g., using cyclic redundancy check (CRC)), forward error correction (FEC) and retransmission (e.g., automatic repeat request (ARQ)). Under poor radio conditions (e.g., signal-to-noise ratio conditions), HARQ may improve the throughput in the MAC layer. In some cases, a wireless device can support HARQ feedback for the same time slot, where the device can provide HARQ feedback for data received in a previous symbol in the time slot in a specific time slot. In other cases, the device can provide HARQ feedback in a subsequent time slot or according to some other time interval.

[0119] The time interval in LTE or NR can be expressed as a multiple of the basic time unit, which can be, for example, T s =1 / 30,720,000 second sampling period. The time intervals of the communication resources may be organized according to radio frames each having a duration of 10 milliseconds (ms), where the frame period may be expressed as T f =307,200T s . A radio frame can be identified by a system frame number (SFN) ranging from 0 to 1023. Each frame can include 10 subframes numbered from 0 to 9, and each subframe can have a duration of 1 millisecond. The subframe can be further divided into 2 time slots, each time slot has a duration of 0.5 ms, and each time slot can contain 6 or 7 modulation symbol periods (e.g., depending on the length of the cyclic prefix before each symbol period). In addition to the cyclic prefix, each symbol period can contain 2048 sampling periods. In some cases, a subframe can be the minimum scheduling unit of the wireless communication system 100 and can be referred to as a transmission time interval (TTI). In other cases, the minimum scheduling unit of the wireless communication system 100 can be shorter than a subframe or can be dynamically selected (e.g., in a burst of a shortened TTI (sTTI) or in a selected component carrier using sTTI).

[0120] In some wireless communication systems, a time slot may be further divided into a plurality of mini-slots containing one or more symbols. In some instances, a symbol of a mini-slot or a mini-slot may be a minimum scheduling unit. For example, the duration of each symbol may vary depending on the subcarrier spacing or the operating frequency band. In addition, some wireless communication systems may implement time slot aggregation, in which a plurality of time slots or mini-slots are aggregated together and used for communication between UE 115 and base station 105.

[0121] The term "carrier" refers to a collection of radio spectrum resources having a defined physical layer structure for supporting communications performed over the communication link 125. For example, a carrier of the communication link 125 may include a portion of a radio frequency spectrum that operates according to a physical layer channel for a given radio access technology. Each physical layer channel may carry user data, control information, or other signaling. A carrier may be associated with a predefined frequency channel (e.g., an Evolved Universal Mobile Telecommunications System Terrestrial Radio Access (E-UTRA) Absolute Radio Frequency Channel Number (EARFCN)) and may be located according to a channel grid for discovery by a UE 115. A carrier may be a downlink or uplink (e.g., in FDD mode), or may be configured to carry downlink and uplink communications (e.g., in TDD mode). In some examples, a signal waveform transmitted over a carrier may be composed of multiple subcarriers (e.g., using a multi-carrier modulation (MCM) technique such as orthogonal frequency division multiplexing (OFDM) or DFT-s-OFDM).

[0122] The organization structure of the carrier can be different for different radio access technologies (e.g., LTE, LTE-A, LTE-A Pro, NR). For example, communications through the carrier can be organized according to TTIs or time slots, each of which can include user data and control information or signaling to support decoding of the user data. The carrier can also include dedicated acquisition signaling (e.g., synchronization signals or system information, etc.) and control signaling to coordinate the operation of the carrier. In some examples (e.g., in a carrier aggregation configuration), the carrier may also have acquisition signaling or control signaling to coordinate the operation of other carriers.

[0123] Physical channels may be multiplexed on a carrier according to various techniques. Physical control channels and physical data channels may be multiplexed on a downlink carrier, for example, using a time division multiplexing (TDM) technique, a frequency division multiplexing (FDM) technique, or a hybrid TDM-FDM technique. In some examples, control information sent in a physical control channel may be distributed in a cascaded manner between different control regions (e.g., between a common control region or common search space and one or more UE-specific control regions or UE-specific search spaces).

[0124] A carrier can be associated with a particular bandwidth of a radio frequency spectrum, and in some examples, the carrier bandwidth can be referred to as the "system bandwidth" of the carrier or wireless communication system 100. For example, the carrier bandwidth can be one of a plurality of predetermined bandwidths of a carrier for a particular radio access technology (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 MHz). In some examples, each serviced UE 115 can be configured to operate on part or all of the carrier bandwidth. In other examples, some UEs 115 can be configured to operate using a narrowband protocol type associated with a predefined portion or range (e.g., a group of subcarriers or resource blocks (RBs)) within a carrier (e.g., an "in-band" deployment of a narrowband protocol type).

[0125] In a system using MCM technology, a resource element may consist of a symbol period (e.g., the duration of a modulation symbol) and a subcarrier, where the symbol period and the subcarrier spacing are 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). Therefore, the more resource elements received by UE 115 and the higher the order of the modulation scheme, the higher the data rate of UE 115. In a MIMO system, wireless communication resources may refer to a combination of radio frequency spectrum resources, time resources, and space resources (e.g., space layers), and the use of multiple space layers may further increase the data rate of communication with UE 115.

[0126] A device (e.g., base station 105 or UE 115) of wireless communication system 100 may have a hardware configuration that supports communication on a specific carrier bandwidth, or may be configured to support communication on one carrier bandwidth in a set of carrier bandwidths. In some examples, wireless communication system 100 may include base stations 105 and / or UEs 115 that support simultaneous communication via carriers associated with more than one different carrier bandwidths.

[0127] The wireless communication system 100 may support communication with the UE 115 on multiple cells or carriers, a feature that may be referred to as carrier aggregation or multi-carrier operation. Depending on the carrier aggregation configuration, the UE 115 may be configured with multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation may be used with both FDD and TDD component carriers.

[0128] In some cases, the wireless communication system 100 can utilize an enhanced component carrier (eCC). An eCC can be characterized by one or more features including a wider carrier or frequency channel bandwidth, a shorter symbol duration, a shorter TTI duration, or a modified control channel configuration. In some cases, an eCC can be associated with a carrier aggregation configuration or a dual connectivity configuration (e.g., when multiple serving cells have suboptimal or non-ideal backhaul links). An eCC can also be configured for use in an unlicensed spectrum or a shared spectrum (e.g., when more than one operator is allowed to use the spectrum). An eCC characterized by a wide carrier bandwidth can include one or more segments that a UE 115 can utilize that are unable to monitor the entire carrier bandwidth or are otherwise configured to use a limited carrier bandwidth (e.g., to save power).

[0129] In some cases, an eCC may utilize a different symbol duration than other component carriers, which may include using a shortened symbol duration compared to the symbol duration of other component carriers. A shorter symbol duration may be associated with an increased spacing between adjacent subcarriers. A device utilizing an eCC (such as a UE 115 or a base station 105) may transmit a wideband signal (e.g., based on a frequency channel or carrier bandwidth of 20, 40, 60, 80 MHz, etc.) in a shortened symbol duration (e.g., 16.67 microseconds). A TTI in an eCC may consist of one or more symbol periods. In some cases, the TTI duration (i.e., the number of symbol periods in a TTI) may be variable.

[0130] The wireless communication system 100 may be an NR system that may utilize any combination of licensed, shared, and unlicensed spectrum bands. The flexibility of eCC symbol duration and subcarrier spacing may allow the use of eCCs across multiple spectrums. In some examples, NR shared spectrum may improve spectrum utilization and spectrum efficiency, particularly through dynamic vertical sharing (e.g., across frequency domains) and horizontal sharing (e.g., across time domains) of resources.

[0131] Conventional wireless communication systems support broadcast reception from broadcast transmitters. Existing wireless communication systems may include broadcast transmitters that send one or more broadcast signals. In one example, the broadcast signal may include one or more multi-resolution messages. In some instances, the UE may receive one or more broadcast transmissions (such as broadcast signals) from the broadcast transmitter. If the UE is located at a position that exceeds a threshold distance from the broadcast transmitter, the UE may not be able to successfully decode one or more multi-resolution messages. Therefore, it may be necessary to improve broadcast technology.

[0132] According to one or more aspects of the present disclosure, UE 115 may include UE communication manager 102. Upon receiving a broadcast signal from a broadcast transmitter, UE communication manager 102 may connect to a nearby base station 105. UE communication manager 102 may determine whether base station 105 includes the ability to relay the broadcast signal. In some cases, UE communication manager 102 may send a signal to base station 105 to query the broadcast reception capability at base station 105. For example, UE communication manager 102 may determine that UE 115 is within the coverage of base station 105. After identifying base station 105, UE communication manager 102 may query base station 105 to determine whether base station 105 has the ability to receive the broadcast signal.

[0133] According to some aspects of the present disclosure, a base station communication manager 101 included in a base station 105 may determine the broadcast reception capability of the base station. In some cases, the broadcast reception capability may include the ability to receive a broadcast signal from a broadcast transmitter. The base station communication manager 101 may receive a signal from the UE communication manager 102 to query the broadcast reception capability. In response to receiving the signal, the base station communication manager 101 may determine the broadcast reception capability. In some cases, the base station communication manager 101 may send a signal indicating the broadcast reception capability of the base station based on determining the broadcast reception capability. The base station communication manager 101 may communicate with the UE 115 based on the broadcast reception capability at the base station 105.

[0134] Figure 2 An example of a wireless communication system 200 supporting a broadcast relay method in NR according to one or more aspects of the present disclosure is shown. In some examples, the wireless communication system 200 can implement aspects of the wireless communication system 100. The wireless communication system 200 may include one or more base stations 105, one or more UEs 115, and a broadcast transmitter 215. For example, the wireless communication system 200 may include base stations 105-a and 105-b and UE 115-a. Figure 2 The base station 105 described in Figure 1 105 - b may be referred to as a network device and / or gNB. UE 115 - a may be a reference Figure 1 An example of a UE 115 is depicted. Base station 105 - a may be an example of a serving base station 105 for UE 115 - a , while base station 105 - b may be an example of a neighboring base station 105 .

[0135] The wireless communication system 200 may illustrate the operation of the base station 105 and the UE 115 supporting the broadcast relay method in NR and the communication therebetween. Each base station 105 may provide a cell, wherein the base station 105 may provide services to the UE 115 within the coverage area of ​​the cell. Figure 2 In the example of , UE 115-a can move within the coverage area, and the cell can provide wireless communication to UE 115-a. In some instances, base station 105 can also be referred to as a small cell. In addition, the UE can receive one or more broadcast transmissions (e.g., broadcast signals) from broadcast transmitter 215. In the wireless communication system 200, broadcast transmitter 215 can send broadcast signals to one or more UEs 115 and one or more base stations 105. In some examples, broadcast transmitter 215 can be referred to as an NR broadcast transmitter. In some cases, broadcast transmitter 215 can be a micro base station, in which a small number of micro base stations cover a larger area. In some examples, broadcast transmitter 215 can transmit at high power. For example, broadcast transmitter 215 can transmit at a higher power than a macro cell.

[0136] In some embodiments, the broadcast transmitter 215 can use a low carrier frequency with a relatively small bandwidth to send NR broadcasts. In conventional wireless communication systems, NR broadcast transmitters cover larger geographic areas. In such cases, if UE 115-a is located at a certain distance from the broadcast transmitter 215 (e.g., NR broadcast transmitter), UE 115-a may not be able to successfully decode the broadcast signal. In one example, the broadcast signal may include one or more multi-resolution messages. For example, the broadcast signal may include multiple messages, each associated with a resolution level. The higher resolution of the message may be associated with a higher signal-to-noise ratio at UE 115-a. If UE 115-a is located at a certain distance from the broadcast transmitter 215, UE 115-a may determine that the signal-to-noise ratio of the broadcast signal is lower. As a result, UE 115-a is able to decode low-resolution messages (such as low-resolution broadcast content) in one or more multi-resolution messages. In one example, a low-resolution message is a message that can be received by a UE when the UE is far away from the transmitter and the SNR is lower than a threshold SNR level. The low-resolution message may be a message with the lowest resolution in a multi-resolution message. In another example, the low-resolution message may have a resolution below a threshold amount. In yet another example, the resolution of the low-resolution message may be lower than the standard resolution of the receiving device. In some embodiments, the UE 115 may receive a high signal-to-noise ratio by decoding multiple code layers in the broadcast signal (or multi-resolution message codewords mapped to each layer). However, if the signal-to-noise ratio is low (i.e., the location of the UE 115 is far from the location of the broadcast transmitter 215), the UE may decode the base layer of the broadcast signal (such as a message associated with a low signal-to-noise ratio threshold).

[0137] In the existing wireless communication system, there is no feedback mechanism for the broadcast transmitter 215. Therefore, if the UE 115 is located far away from the broadcast transmitter 215, the UE 115 is able to decode the base layer (i.e., the layer including low data content) associated with the broadcast signal. The low data content can be any amount of data below the threshold level. In addition, if the UE 115 is located closer to the broadcast transmitter 215, the UE 115 is able to decode the second layer associated with the broadcast signal (e.g., multiple messages included in the broadcast signal). In some cases, the second layer associated with the broadcast signal can be an enhancement layer with a higher modulation and decoding scheme. In some cases, the broadcast transmitter 215 may not know the number and location of the UEs within its coverage area 210-a. In addition, the UE 115 may not be able to indicate the decoding failure to the broadcast transmitter 215. Therefore, it may be necessary to improve the broadcast technology. Some examples of the wireless communication system 200 can support improving the broadcast procedure in NR. In some cases, the UE 115 and the base station 105 can support the broadcast relay method.

[0138] According to one or more aspects of the present disclosure, UE 115-a can utilize one or more base stations 105 to receive relays of broadcast signals. In an NR system, base stations 105 (referred to as NR small cells) can be deployed so that UE 115-a is located close to one or more base stations 105. In some cases, NR small cells (e.g., base stations 105) are powerful in terms of the number or performance of antennas. In addition, due to the smaller coverage area 210-b, UE 115-a can be located in a more strategic position from base station 105. In some cases, UE 115-a may be far away from the line of sight of broadcast transmitter 215. However, the NR small cell may be located on the top of a building or on the top of a lamppost, so there is a greater chance of entering the line of sight and less fading. According to one aspect, one or more base stations 105 can be in a better signal-to-noise ratio condition to receive broadcast signals from a broadcast transmitter 215 (e.g., an NR broadcast transmitter). In some cases, the one or more base stations 105 can then relay the received broadcast signal to UE 115-a. Relaying broadcast signals by an NR small cell (e.g., base station 105) can allow UE 115-a to receive high-resolution broadcast content.

[0139] According to one or more aspects of the present disclosure, UE 115-a may receive a broadcast signal 205 from a broadcast transmitter 215. In some cases, the broadcast signal 205 may include one or more multi-resolution messages. In some embodiments, the broadcast signal includes one or more system information bits and one or more redundant decoding bits. Upon receiving the broadcast signal 205, UE 115-a may attempt to decode the broadcast signal. For example, UE 115-a may decode at least one of the one or more multi-resolution messages based on receiving the broadcast signal 205 from the broadcast transmitter 215. In one example, UE 115-a determines that the data rate associated with the broadcast signal is less than a threshold based on decoding at least one of the one or more multi-resolution messages. For example, UE 115-a may determine that it is able to decode one of the multi-resolution messages included in the broadcast signal 205. In such cases, UE 115-a may determine that the decoded message includes low data content. In such cases, UE 115-a may send a signal 230 to query the broadcast reception capability of base station 105-a. In some embodiments, UE 115-a can determine that it is connected to a nearby small cell (i.e., base station 105-a), and UE 115-a can query base station 105-a to determine whether base station 105-a has the ability to receive and relay broadcast signals. Base station 105-a can receive signal 230 querying the broadcast reception capability of base station 105-a, and can determine whether base station 105-a includes the ability to receive broadcast transmissions from broadcast transmitter 215.

[0140] Different base stations may have different capabilities and conditions with respect to receiving broadcast signals and relaying broadcast signals to UE 115-a. In some cases, base station 105-a may indicate (via signal 230) that base station 105-a has the ability to receive broadcast signals from broadcast transmitter 215. Upon receiving the indication from base station 105-a, UE 115-a may determine the link quality between base station 105-a and UE 115-a. In some cases, if the link quality exceeds a threshold, UE 115-a may select base station 105-a for relaying broadcast signals. Therefore, unlike the conventional manner of selecting a base station (or small cell) (in the conventional manner, UE 115 selects the nearest base station), the techniques described in the present disclosure provide selection criteria for considering broadcast links and relay links associated with base stations. In some examples, instead of querying one base station (in this example, base station 105-a), UE 115-a may contact multiple base stations. In some cases, each of the multiple base stations may inform UE 115-a of the capability and conditions for receiving the broadcast signal. Upon receiving the capability information from each base station, UE 115-a may select a base station for receiving a relay of the broadcast signal.

[0141] According to some aspects of the present disclosure, the base station 105-a may receive a broadcast signal 220 from a broadcast transmitter 215. In some cases, the base station 105-a may relay the broadcast signal to the UE 115-a. In some examples, the base station 105-a may broadcast a signal 230 indicating a broadcast reception capability using a first frequency, and may receive the broadcast signal 220 from the broadcast transmitter 215 using a second frequency. Additionally or alternatively, the base station 105-a may determine that the base station 105-a cannot receive the broadcast signal from the broadcast transmitter 215. In some cases, the base station 105-a may send a signal indicating that the base station 105-a cannot receive the broadcast signal from the broadcast transmitter 215. After receiving an indication of the broadcast reception capability of the base station 105-a, the UE 115-a may send a signal to query the broadcast reception capability of the second base station 105-b.

[0142] In some examples, UE 115-a may receive an indication from a second base station 105-b that second base station 105-b includes the ability to receive broadcast signals from broadcast transmitter 215. In such cases, UE 115-a may determine a first link quality between UE 115-a and base station 105-a and a second link quality between UE 115-a and second base station 105-b. If the link quality between UE 115-a and second base station 105-b is greater than a threshold, UE 115-a may perform a handover procedure to connect to second base station 105-b (so that second base station 105-b may relay broadcast signals received from the broadcast transmitter). Alternatively, if the link quality between UE 115-a and second base station 105-b is less than a threshold, and if the link quality between UE 115-a and base station 105-a satisfies the threshold, UE 115-a may use a multi-hop technique to receive the broadcast signal. That is, the second base station 105-b may receive the broadcast signal 235 from the broadcast transmitter 215 and relay the broadcast signal to the base station 105-a. The base station 105-a may then relay the broadcast signal to the UE 115-a.

[0143] In some examples, base station 105-a may determine that base station 105-a does not include the capability to receive broadcast transmissions from broadcast transmitter 215. In such cases, base station 105-a may send signal 240 for querying the broadcast reception capability of second base station 105-b. Base station 105-a may receive an indication from second base station 105-b that second base station 105-b includes the capability to receive broadcast signals from broadcast transmitter 215. In some embodiments, base station 105-a may then indicate the broadcast reception capability of second base station 105-b to UE 115-a.

[0144] In one or more examples, a broadcast channel (e.g., a channel including a broadcast signal) may use a frequency band different from that of enhanced wireless broadband (e.g., a channel for wireless communication between base station 105 and UE 115). Because broadcast channels are associated with higher penetration rates, broadcast signals are typically associated with low carrier frequencies. On the other hand, the link between base station 105 and UE115-a may use mmW frequencies (such as 38 GHz). In some examples, the broadcast reception capability at base station 105 may be based on at least one of the following: circuits included in the base station, broadcast reception quality at the base station, current load at the base station, or a combination thereof. For example, one or more hardware (such as a radio frequency link) may limit the base station 105 to include the ability to receive broadcast signals from a broadcast transmitter. For example, base station 105 may be located in a dense deployment and may not support low carrier frequencies. Additionally or alternatively, base station 105 may support low carrier frequencies, but the current broadcast reception quality may be less than a threshold. In such cases, base station 105 may indicate that base station 105 cannot receive broadcast signals from broadcast transmitter 215.

[0145] According to one or more aspects, UE 115-a may send a signal to the central entity for querying the broadcast reception capability of base station 105-a. In some cases, UE 115-a may indicate to the central entity the link quality between base station 105-a and UE 115-a. In some examples, the central entity may know the capabilities and conditions for receiving broadcast signals of multiple base stations 105, and may make a selection determination for UE 115-a. That is, the central entity may select a base station 105 suitable for relaying the broadcast signal to UE 115-a. In some cases, the central entity may indicate that the base station includes the capability to receive broadcast signals from a broadcast transmitter.

[0146] According to one or more aspects of the present disclosure, UE 115-a may receive a configuration signal indicating a transmission mode of base station 105. For example, UE 115-a may receive the configuration signal (e.g., a radio resource control signal) from base station 105-a. In some cases, UE 115-a may select base station 105-a to receive a relay of a broadcast signal before receiving the configuration signal. In some cases, UE 115-a may monitor at least a portion of a time slot for receiving a relay signal from base station 105-a based on the transmission mode of base station 105-a. In some cases, the relay signal is a relay of a broadcast signal sent from a broadcast transmitter 215. Base station 105-a may receive a broadcast signal from broadcast transmitter 215, and may send a broadcast signal to UE 115-a based on the transmission mode of base station 105-a. For example, base station 105-a may indicate the start time of the transmission mode to UE 115-a. In some cases, the start time of the transmission mode coincides with the start time of the reception mode at UE 115-a.

[0147] In some embodiments, the start time of the transmission mode of the base station 105-a can be indicated to the UE 115-a based on the conditions for receiving the broadcast signal. In such cases, the UE can determine the start time for receiving the relay signal (i.e., the relay of the broadcast signal) in each frame. Alternatively, the timing of sending the relay signal can be flexible in the case where the UE 115-a monitors multiple predefined instances for receiving the relay signal from the base station 105-a. In some embodiments, the UE 115-a can identify the start time for receiving the relay signal from the base station 105-a based on the transmission mode of the base station 105-a. The UE 115-a can then initiate monitoring of the time slot at the identified start time to receive the relay signal from the base station 105-a. In some instances, the UE 115-a can receive a physical downlink control channel based on the transmission mode of the base station. The UE 115-a can initiate monitoring of at least part of the time slot for receiving the relay signal from the base station 105-a based on receiving the physical downlink control channel. In some cases, UE 115-a also monitors certain time instances for receiving a physical downlink control channel. The time instances may be based on at least one of a transmission mode of the base station, a configuration signal, or a combination thereof. In some cases, UE 115-a may monitor the physical downlink control channel when base station 105-a is in a receive mode (i.e., when base station 105-a is receiving a broadcast transmission from broadcast transmitter 215).

[0148] In some examples, UE 115-a may monitor one or more broadcast transmissions from broadcast transmitter 215 while monitoring a relay signal (or a relay or broadcast signal) from base station 105-a. Alternatively, UE 115-a may shut down a receive chain associated with a low carrier frequency (such as a receive chain intended for receiving a broadcast signal from broadcast transmitter 215) while monitoring the relay signal. In some cases, the timing boundary associated with receiving the relay signal may be equal to the timing boundary associated with receiving the broadcast signal. That is, both receiving the relay signal and receiving the broadcast signal may be completed before the frame is completed (e.g., 10ms). In some examples, the modulation and decoding scheme associated with the relay signal (i.e., the relay of the broadcast signal) may be greater than the modulation and decoding scheme associated with the broadcast signal. In some cases, the relay signal includes an in-band signal, an out-of-band signal, or both. Additionally or alternatively, the relay signal may be sent using mmW frequencies, and the broadcast signal may be sent using sub-6 frequencies (e.g., a frequency range below 6 GHz, in the range of 1 GHz to 6 GHz).

[0149] Therefore, the present disclosure provides a relay method for a broadcast signal, in which a UE attempts to connect to a nearby base station while receiving a broadcast signal from a broadcast transmitter, and checks whether the base station includes a capability of relaying the broadcast signal.

[0150] Figure 3 An example of a timing diagram 300 for supporting a broadcast relay method in NR according to one or more aspects of the present disclosure is shown. In some examples, the timing diagram 300 may implement aspects of the wireless communication system 100 and / or the wireless communication system 200. According to one or more aspects of the present disclosure, the UE 115 may determine that the data rate associated with the broadcast signal is less than a threshold level. When determining the data rate, the UE 115 may utilize one or more base stations 105 to receive a relay of the broadcast signal. In one example, the UE 115 may be connected to the base station 105 (or small cell) and may check whether the base station 105 includes the ability to relay the broadcast signal. In some cases, the UE 115 may receive an indication of the broadcast reception capability of the base station 105. For example, the base station 105 may indicate that it has the ability to receive a broadcast signal from a broadcast transmitter. In some cases, if the link quality between the base station 105 and the UE 115 meets the threshold, the UE 115 may select the base station 105 to receive the relay of the broadcast signal (or relay signal). When selecting the base station 105, the UE 115 may receive a configuration signal from the base station 105. In some examples, the configuration signal may include: a transmission mode for base station 105.

[0151] like Figure 3As described in the foregoing, the base station 105 may receive a broadcast signal from a broadcast transmitter. The broadcast signal may include system information bits 305 and redundant decoded bits 310. In some examples, the base station 105 may receive the broadcast signal at time t0 330. The base station 105 may start receiving the broadcast signal during the receiving mode 315 of the base station. The receiving mode 315 of the base station may also start at time t0 330. Upon receiving the broadcast signal, the base station 105 decodes the broadcast signal and re-encodes the broadcast signal. The base station 105 may then send the re-encoded broadcast signal to the UE 115. In some cases, the base station 105 may send the re-encoded broadcast signal during the transmission mode 320 of the base station 105. In some cases, the base station 105 may send a relay signal to the UE 115 in a unicast manner. In this example, the start time of the transmission mode 320 for the base station 105 is at time t1 335. UE 115 may receive the relay signal from base station 105 during the UE's receive mode 325. In one example, the UE's receive mode 325 is aligned with the base station 105's transmit mode 320. In some cases, a configuration signal may be used to indicate to UE 115 the start time of the base station 105's transmit mode (time t1 335). In some cases, the transmission of the relay signal is completed no later than the end of the frame of the original broadcast signal (i.e., time t2 340). Completing the reception of the relay signal at the end of the frame can ensure that the relay operation does not add any delay.

Alternatively, the timing of sending the relay signal may be flexible in the case where the UE 115 monitors multiple time instances for reception of the relay signal from the base station 105.

In some examples, the timing diagram 400 may implement aspects of the wireless communication system 100 and / or the wireless communication system 200. According to one or more aspects of the present disclosure, the UE 115 may utilize one or more base stations 105 to receive a relay of a broadcast signal. In order to receive the relay of the broadcast signal, the UE 115 may be connected to a first base station 105 (or a small cell) and may check whether the first base station 105 includes the ability to relay the broadcast signal. In some cases, the UE 115 may receive an indication of the broadcast reception capability of the first base station 105. In some examples, the first base station 105 may indicate that it cannot receive a broadcast signal from a broadcast transmitter. In some cases, the UE 115 may send a query to the second base station 105. For example, the UE 115 may query the broadcast reception capability of the second base station 105. In some cases, the UE 115 may determine that the second base station has the ability to receive the broadcast signal from the broadcast transmitter. However, the link quality between the second base station 105 and the UE 115 may be less than a threshold. In addition, the link quality between the first base station 105 and the UE 115 may meet a threshold. In such cases, the UE 115 may use a multi-hop technique to receive a relay of a broadcast signal. Specifically, the second base station 105 may receive a broadcast signal from a broadcast transmitter and relay the broadcast signal to the first base station 105. The first base station 105 may then relay the broadcast signal to the UE 115. In some embodiments, the UE 115 may receive a configuration signal from the first base station 105. In some examples, the configuration signal may include a transmission mode for the first base station 105.

The broadcast signal may include system information bits 405 and redundant decoding bits 410. In some examples, the second base station 105 may begin receiving the broadcast signal at time t0 440. The second base station 105 may receive the broadcast signal during a second base station reception mode 415, where the second base station reception mode 415 may start at time t0 440. In some cases, the second base station 105 decodes the broadcast signal and re-encodes the broadcast signal within the second base station reception mode 415. The second base station 105 may then send the re-encoded broadcast signal to the first base station 105. In some cases, the second base station 105 may send the re-encoded broadcast signal during the second base station 105 transmission mode 420. In Figure 4445. In some examples, the first base station 105 may receive a relay signal from the second base station 105 during the receive mode 425 of the first base station 105. The first base station 105 may then send the relay signal during the transmission mode 430 of the first base station 105. In this example, the start time of the transmission mode 430 of the first base station 105 is at time t2 450. The UE 115 may receive the relay signal from the first base station 105 during the receive mode 435 of the UE. Figure 4 As depicted in the example of , the UE's reception mode 435, the first base station 105's transmission mode 430, and the second base station 105's transmission mode 420 may be completed no later than the end of the frame of the original broadcast signal (ie, time t3 440).

[0384] The wireless communication systems described herein may support synchronous or asynchronous operation. For synchronous operation, base stations may have similar frame timings, and transmissions from different base stations may be approximately aligned in time. For asynchronous operation, base stations may have different frame timings, and transmissions from different base stations may have different timelines. The techniques described herein may be used for synchronous or asynchronous operation.

[0385] The information and signals described herein may be represented using any of a variety of different technologies and techniques. For example, data, instructions, commands, information, signals, bits, symbols, and chips that may be mentioned throughout the description may be represented by voltage, current, electromagnetic waves, magnetic fields or particles, optical fields or particles, or any combination thereof.

[0386] The various illustrative blocks and modules described in conjunction with the disclosure herein may be implemented or performed with a general purpose processor, a DSP, an ASIC, an FPGA, or other programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof designed to perform the functions described herein. A general purpose processor may be a microprocessor, but optionally, the processor may be any conventional processor, controller, microcontroller, or state machine. The processor may also be implemented as a combination of computing devices (e.g., a combination of a DSP and a microprocessor, a plurality of microprocessors, one or more microprocessors in combination with a DSP core, or any other such configuration).

[0387] The functions described herein may be implemented in hardware, software executed by a processor, firmware, or any combination thereof. If implemented in software executed by a processor, the functions may be stored on or sent via a computer-readable medium as one or more instructions or codes. Other examples and implementations are within the scope of the present disclosure and the appended claims. For example, due to the nature of software, the functions described herein may be implemented using software executed by a processor, hardware, firmware, hard wiring, or any combination of these. Features that implement the functions may also be physically located in a variety of locations, including being distributed so that parts of the functions are implemented at different physical locations.

[0388] Computer-readable media include both non-transitory computer storage media and communication media (including any media that facilitates the transfer of computer programs from one place to another). Non-transitory storage media can be any available media that can be accessed by a general or special computer. For example and without limitation, non-transitory computer-readable media can include RAM, ROM, electrically erasable programmable ROM (EEPROM), compact disc (CD) ROM, flash memory, or other optical disc storage devices, magnetic disk storage devices or other magnetic storage devices, or can be used to carry or store the required program code method in the form of instructions or data structures and can be accessed by a general or special computer, or a general or special processor. Any other non-transitory medium. Moreover, any connection is appropriately referred to as a computer-readable medium. For example, if software is sent from a website, server or other remote source using coaxial cable, optical cable, twisted pair, digital subscriber line (DSL) or wireless technologies such as infrared, radio and microwave, coaxial cable, optical fiber cable, twisted pair, DSL or wireless technologies such as infrared, radio and microwave are included in the definition of the medium. Disk and disc, as used herein, includes CD, laser disc, optical disc, digital versatile disc (DVD), floppy disk and Blu-ray disc, where disks usually reproduce data magnetically, while discs reproduce data optically with the aid of lasers. Combinations of the above are also included within the scope of computer-readable media.

[0389] Moreover, as used herein (including in the claims), "or" as used in a list of items (e.g., a list of items beginning with a phrase such as "at least one of..." or "one or more") indicates an inclusive list, so that, for example, at least one of 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). Moreover, as used herein, the phrase "based on" should not be interpreted as a reference to a closed set of conditions. For example, an exemplary operation described as "based on condition A" can be based on both condition A and condition B without departing from the scope of the present disclosure. In other words, as used herein, the phrase "based on" should be interpreted in the same manner as the phrase "based at least in part on."

[0390] In the drawings, similar components or features may have the same reference label. In addition, various components of the same type may be distinguished by following the reference label with a dash and a second label that distinguishes the similar components. If only the first numerical reference label is used in the specification, the description applies to any of the similar components having the same first reference label, regardless of the second or other subsequent reference labels.

[0391] The descriptions set forth herein in conjunction with the accompanying drawings describe exemplary configurations and do not represent all examples that may be implemented or within the scope of the claims. The term "exemplary" as used herein means "used as an example, paradigm, or illustration," rather than "preferred" or "superior to other examples." In order to provide an understanding of the described techniques, the detailed description includes specific details. However, these techniques may be practiced without these specific details. In some examples, well-known structures and devices are shown in block diagram form in order to avoid making the concepts of the described examples unclear.

[0392] The description herein is provided to enable those skilled in the art to make or use the present disclosure. Various modifications to the present 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 the present disclosure. Therefore, the present disclosure is not limited to the examples and designs described herein, but should be given the broadest scope consistent with the principles and novel features disclosed herein.
