Hereinafter, 5G communication (5th generation mobile communication) required by an apparatus requiring AI processed information and/or an AI processor will be described through sections A through G. Further, communication generation(s) above/below 5G communication may be used alone or in conjunction with 5G communication if applicable.

Three major requirement areas of 5G include (1) an enhanced mobile broadband (eMBB) area, (2) a massive machine type communication (mMTC) area, and (3) ultra-reliable and low latency communications (URLLC) area.
Some use cases can require multiple areas for optimization, and other use cases can be focused to only one key performance indicator (KPI). 5G supports these various use cases in a flexible and reliable manner.
The EMBB enables far beyond basic mobile Internet access and covers media and entertainment applications in rich interactive work, cloud or augmented reality. Data is one of key dynamic power of 5G, and in a 5G era, a dedicated voice service may not be seen for the first time. In 5G, a voice is expected to be treated as an application program using data connection simply provided by a communication system. Main reasons for an increased traffic volume are increase in content size and increase in the number of applications requiring a high data transmission rate. Streaming services (audio and video), interactive video, and mobile Internet connections will be used more widely as more devices connect to Internet. These many application programs require always-on connectivity in order to push real-time information and notifications to a user. Cloud storage and applications are growing rapidly in mobile communication platforms, which can be applied to both work and entertainment. Cloud storage is a special use case that drives growth of uplink data transmission rates. 5G is also used for remote tasks in cloud and requires much lower end-to-end delays so as to maintain excellent user experience when tactile interfaces are used. Entertainment, for example, cloud gaming and video streaming is another key factor in increasing the need for mobile broadband capabilities. Entertainment is essential in smartphones and tablets at anywhere including in high mobility environments such as trains, cars and airplanes. Another use case is augmented reality and information search for entertainment. Here, augmented reality requires very low latency and instantaneous amount of data.
Further, one of most anticipated 5G use cases relates to a function, i.e., mMTC that can smoothly connect embedded sensors in all fields. By 2020 year, potential IoT devices are expected to reach 20.4 billion. Industrial IoT is one of areas in which 5G plays a major role in enabling smart cities, asset tracking, smart utilities, and agriculture and security infrastructure.
URLLC includes new services to transform an industry through ultra-reliable/available low latency links, such as remote control of major infrastructure and self-driving vehicles. A level of reliability and latency is essential for smart grid control, industrial automation, robotics, drone control, and coordination.
Hereinafter, a number of use cases are described in more detail.
5G can complement fiber-to-the-home (FTTH) and cable-based broadband (or DOCSIS) as a means of providing streams that are rated at hundreds of megabits per second to gigabits per second. Such a high speed is required to deliver televisions with a resolution of 4K or more (6K, 8K, and more) as well as virtual reality and augmented reality. Virtual Reality (VR) and Augmented Reality (AR) applications include nearly immersive sporting events. A specific application program can require a special network setting. For example, for VR games, in order to minimize latency, game companies can need to integrate core servers with an edge network server of a network operator.
An automotive is expected to become important new dynamic power for 5G together with many use cases for mobile communication to vehicles. For example, entertainment for passengers requires simultaneous high capacity and high mobility mobile broadband. This is because future users continue to expect high quality connections regardless of a position and speed thereof. Another use case of an automotive sector is an augmented reality dashboard. This identifies objects in the dark above what a driver views through a front window and overlays and displays information that notifies the driver about a distance and movement of the object. In the future, wireless modules enable communication between vehicles, exchange of information between a vehicle and a supporting infrastructure, and exchange of information between a vehicle and other connected devices (e.g., devices carried by pedestrians). A safety system guides alternative courses of an action to enable drivers to safer drive, thereby reducing the risk of an accident. The next step will be a remotely controlled or self-driven vehicle. This requires very reliable and very fast communication between different self-driving vehicles and between automobiles and infrastructure. In the future, self-driving vehicles will perform all driving activities and the driver will focus on traffic anomalies that the vehicle itself cannot identify. The technical requirements of self-driving vehicles require ultra-low latency and ultra-fast reliability so as to increase traffic safety to an unachievable level.
Smart cities and smart homes, referred to as smart societies, will be embedded in a high density wireless sensor network. A distributed network of intelligent sensors will identify conditions for a cost and energy-efficient maintenance of a city or a home. Similar settings can be made for each family. Temperature sensors, window and heating controllers, burglar alarms and home appliances are all connected wirelessly. These many sensors are typically low data rates, low power and low cost. However, for example, real-time HD video can be required in a specific type of device for surveillance.
Consumption and distribution of energy including a heat or a gas is highly decentralized, thereby requiring automated control of distributed sensor networks. Smart grids interconnect these sensors using digital information and communication technology so as to collect information and act accordingly. The information can include a behavior of suppliers and consumers, allowing smart grids to improve distribution of fuels such as electricity in efficiency, reliability, economics, sustainability of production, and in an automated manner. Smart grid can be viewed as another sensor network with low latency.
A health sector has many application programs that can benefit from mobile communication. The communication system can support telemedicine that provides clinical care at a far distance. This can help reduce barriers to distance and improve access to healthcare services that are not consistently available in remote rural areas. It is also used for saving lives in important care and emergency situations. A mobile communication based wireless sensor network can provide remote monitoring and sensors for parameters such as a heart rate and a blood pressure.
Wireless and mobile communication is becoming gradually important in an industrial application field. A wiring requires a highly installing and maintaining cost. Therefore, the possibility of replacing with a wireless link that can reconfigure a cable is an attractive opportunity in many industry fields. However, achieving this requires that a wireless connection operates with reliability, capacity, and delay similar to a cable and that management is simplified. Low latency and very low error probability are new requirements that need to be connected in 5G.
Logistics and freight tracking are important use cases for mobile communication that enable tracking of inventory and packages at anywhere using a position-based information system. A use case of logistics and freight tracking typically requires a low data rate, but requires reliable position information and a wide range.
The present disclosure to be described later in the present specification can be implemented by combining or changing each embodiment so as to satisfy the requirements of the above-described 5G.

B. Signal Transmission/Reception Method in Wireless Communication System
In a wireless communication system, a UE (user equipment) receives information from a base station through downlink (DL), and the UE transmits information to the base station through uplink (UL). The information transmitted and received by the base station and the UE includes data and various control information, and various physical channels exist according to a kind/use of information in which the base station and the UE transmit and receive.
When power of the UE is turned on or when the UE newly enters to a cell, the UE performs an initial cell search operation of synchronizing with the base station (S201). For this reason, the UE can receive a primary synchronization signal (PSS) and a secondary synchronization signal (SSS) from the base station to be synchronized with the base station and obtain information such as cell ID. Thereafter, the UE can receive a physical broadcast channel (PBCH) from the base station to obtain broadcast information within the cell. The UE can receive a downlink reference signal (DL RS) in an initial cell search step to check a downlink channel status.
The UE, having finished initial cell search can receive a physical downlink shared channel (PDSCH) according to a physical downlink control channel (PDCCH) and information loaded in the PDCCH to obtain more specific system information (S202).
When the UE first accesses to the base station or when there is no radio resource for signal transmission, the UE can perform a random access procedure (RACH) to the base station (S203 to S206). For this reason, the UE can transmit a specific sequence to a preamble through a physical random access channel (PRACH) (S203 and S205) and receive a random access response (RAR) message to the preamble through the PDCCH and the PDSCH corresponding thereto. In the case of a contention-based RACH, the UE can additionally perform a contention resolution procedure (S206).
The UE, having performed the above process can perform PDCCH/PDSCH reception (S207) and physical uplink shared channel (PUSCH)/physical uplink control channel (PUCCH) transmission (S208) as a general uplink/downlink signal transmission procedure. In particular, the UE receives downlink control information (DCI) through the PDCCH. Here, the DCI includes control information such as resource allocation information for the UE and can be applied in different formats according to a use purpose.
Control information transmitted by the UE to the base station through uplink or received by the UE from the base station can include a downlink/uplink ACK/NACK signal, a channel quality indicator (CQI), a precoding matrix index (PMI), and a rank indicator (RI). The UE can transmit control information such as the above-described CQI/PMI/RI through a PUSCH and/or a PUCCH.
The UE monitors a set of PDCCH candidates at monitoring occasions set to at least one control element sets (CORESETs) on a serving cell according to the corresponding search space configurations. A set of PDCCH candidates to be monitored by the UE is defined in terms of search space sets, and the search space sets can be a common search space set or a UE-specific search space set. The CORESET is configured with a set of (physical) resource blocks having time duration of 1 to 3 OFDM symbols. The network can set the UE to have a plurality of CORESETs. The UE monitors PDCCH candidates in at least one search space sets. Here, monitoring means attempting to decode the PDCCH candidate(s) in the search space. When the UE succeeds in decoding one of PDCCH candidates in a search space, the UE determines that the PDCCH has been detected in the corresponding PDCCH candidate, and performs PDSCH reception or PUSCH transmission based on DCI in the detected PDCCH. The PDCCH can be used for scheduling DL transmissions on the PDSCH and UL transmissions on the PUSCH. Here, DCI on the PDCCH includes a downlink assignment (i.e., downlink grant (DL grant)) including at least modulation and coding format and resource allocation information related to a downlink shared channel or uplink grant (UL grant) including modulation and coding format and resource allocation information related to an uplink shared channel.
An initial access (IA) procedure in a 5G communication system will be additionally described with reference to
The UE can perform cell search, system information acquisition, beam alignment for initial access, and DL measurement on the basis of an SSB (synchronization signal block). The SSB is interchangeably used with a synchronization signal/physical broadcast channel (SS/PBCH) block.
The SSB includes a PSS, an SSS and a PBCH. The SSB is configured in four consecutive OFDM symbols, and a PSS, a PBCH, an SSS/PBCH or a PBCH is transmitted for each OFDM symbol. Each of the PSS and the SSS includes one OFDM symbol and 127 subcarriers, and the PBCH includes 3 OFDM symbols and 576 subcarriers.
Cell search refers to a process in which a UE acquires time/frequency synchronization of a cell and detects a cell identifier (ID) (e.g., physical layer cell ID (PCI)) of the cell. The PSS is used to detect a cell ID in a cell ID group and the SSS is used to detect a cell ID group. The PBCH is used to detect an SSB (time) index and a half-frame.
There are 336 cell ID groups and there are 3 cell IDs per cell ID group. A total of 1008 cell IDs are present. Information on a cell ID group to which a cell ID of a cell belongs is provided/acquired through an SSS of the cell, and information on the cell ID among 336 cell ID groups is provided/acquired through a PSS.
The SSB is periodically transmitted in accordance with SSB periodicity. A default SSB periodicity assumed by a UE during initial cell search is defined as 20 ms. After cell access, the SSB periodicity can be set to one of {5 ms, 10 ms, 20 ms, 40 ms, 80 ms, 160 ms} by a network (e.g., a BS).
Next, acquisition of system information (SI) will be described.
SI is divided into a master information block (MIB) and a plurality of system information blocks (SIBs). SI other than the MIB can be referred to as remaining minimum system information. The MIB includes information/parameter for monitoring a PDCCH that schedules a PDSCH carrying SIB1 (SystemInformationBlockl) and is transmitted by a BS through a PBCH of an SSB. SIB1 includes information related to availability and scheduling (e.g., transmission periodicity and SI-window size) of the remaining SIBs (hereinafter, SIBx, x is an integer equal to or greater than 2). SiBx is included in an SI message and transmitted over a PDSCH. Each SI message is transmitted within a periodically generated time window (i.e., SI-window).
A random access (RA) procedure in a 5G communication system will be additionally described with reference to
A random access procedure is used for various purposes. For example, the random access procedure can be used for network initial access, handover, and UE-triggered UL data transmission. A UE can acquire UL synchronization and UL transmission resources through the random access procedure. The random access procedure is classified into a contention-based random access procedure and a contention-free random access procedure. A detailed procedure for the contention-based random access procedure is as follows.
A UE can transmit a random access preamble through a PRACH as Msg1 of a random access procedure in UL. Random access preamble sequences having different two lengths are supported. A long sequence length 839 is applied to subcarrier spacings of 1.25 kHz and 5 kHz and a short sequence length 139 is applied to subcarrier spacings of 15 kHz, 30 kHz, 60 kHz and 120 kHz.
When a BS receives the random access preamble from the UE, the BS transmits a random access response (RAR) message (Msg2) to the UE. A PDCCH that schedules a PDSCH carrying a RAR is CRC masked by a random access (RA) radio network temporary identifier (RNTI) (RA-RNTI) and transmitted. Upon detection of the PDCCH masked by the RA-RNTI, the UE can receive a RAR from the PDSCH scheduled by DCI carried by the PDCCH. The UE checks whether the RAR includes random access response information with respect to the preamble transmitted by the UE, that is, Msg1. Presence or absence of random access information with respect to Msg1 transmitted by the UE can be determined according to presence or absence of a random access preamble ID with respect to the preamble transmitted by the UE. If there is no response to Msg1, the UE can retransmit the RACH preamble less than a predetermined number of times while performing power ramping. The UE calculates PRACH transmission power for preamble retransmission on the basis of most recent pathloss and a power ramping counter.
The UE can perform UL transmission through Msg3 of the random access procedure over a physical uplink shared channel on the basis of the random access response information. Msg3 can include an RRC connection request and a UE ID. The network can transmit Msg4 as a response to Msg3, and Msg4 can be handled as a contention resolution message on DL. The UE can enter an RRC connected state by receiving Msg4.
C. Beam Management (BM) Procedure of 5G Communication System
A BM procedure can be divided into (1) a DL MB procedure using an SSB or a CSI-RS and (2) a UL BM procedure using a sounding reference signal (SRS). In addition, each BM procedure can include Tx beam swiping for determining a Tx beam and Rx beam swiping for determining an Rx beam.
The DL BM procedure using an SSB will be described.
Configuration of a beam report using an SSB is performed when channel state information (CSI)/beam is configured in RRC_CONNECTED.
When a CSI-RS resource is configured in the same OFDM symbols as an SSB and ‘QCL-T eD’ is applicable, the UE can assume that the CSI-RS and the SSB are quasi co-located (QCL) from the viewpoint of ‘QCL-TypeD’. Here, QCL-TypeD can mean that antenna ports are quasi co-located from the viewpoint of a spatial Rx parameter. When the UE receives signals of a plurality of DL antenna ports in a QCL-TypeD relationship, the same Rx beam can be applied.
Next, a DL BM procedure using a CSI-RS will be described.
An Rx beam determination (or refinement) procedure of a UE and a Tx beam swiping procedure of a BS using a CSI-RS will be sequentially described. A repetition parameter is set to ‘ON’ in the Rx beam determination procedure of a UE and set to ‘OFF’ in the Tx beam swiping procedure of a BS.
First, the Rx beam determination procedure of a UE will be described.
Next, the Tx beam determination procedure of a BS will be described.
Next, the UL BM procedure using an SRS will be described.
The UE determines Tx beamforming for SRS resources to be transmitted on the basis of SRS-SpatialRelation Info included in the SRS-Config IE. Here, SRS-SpatialRelation Info is set for each SRS resource and indicates whether the same beamforming as that used for an SSB, a CSI-RS or an SRS will be applied for each SRS resource.
Next, a beam failure recovery (BFR) procedure will be described.
In a beamformed system, radio link failure (RLF) can frequently occur due to rotation, movement or beamforming blockage of a UE. Accordingly, NR supports BFR in order to prevent frequent occurrence of RLF. BFR is similar to a radio link failure recovery procedure and can be supported when a UE knows new candidate beams. For beam failure detection, a BS configures beam failure detection reference signals for a UE, and the UE declares beam failure when the number of beam failure indications from the physical layer of the UE reaches a threshold set through RRC signaling within a period set through RRC signaling of the BS. After beam failure detection, the UE triggers beam failure recovery by initiating a random access procedure in a PCell and performs beam failure recovery by selecting a suitable beam. (When the BS provides dedicated random access resources for certain beams, these are prioritized by the UE). Completion of the aforementioned random access procedure is regarded as completion of beam failure recovery
D. URLLC (Ultra-Reliable and Low Latency Communication)
URLLC transmission defined in NR can refer to (1) a relatively low traffic size, (2) a relatively low arrival rate, (3) extremely low latency requirements (e.g., 0.5 and 1 ms), (4) relatively short transmission duration (e.g., 2 OFDM symbols), (5) urgent services/messages, etc. In the case of UL, transmission of traffic of a specific type (e.g., URLLC) needs to be multiplexed with another transmission (e.g., eMBB) scheduled in advance in order to satisfy more stringent latency requirements. In this regard, a method of providing information indicating preemption of specific resources to a UE scheduled in advance and allowing a URLLC UE to use the resources for UL transmission is provided.
NR supports dynamic resource sharing between eMBB and URLLC. eMBB and URLLC services can be scheduled on non-overlapping time/frequency resources, and URLLC transmission can occur in resources scheduled for ongoing eMBB traffic. An eMBB UE may not ascertain whether PDSCH transmission of the corresponding UE has been partially punctured and the UE may not decode a PDSCH due to corrupted coded bits. In view of this, NR provides a preemption indication. The preemption indication can also be referred to as an interrupted transmission indication.
With regard to the preemption indication, a UE receives DownlinkPreemption IE through RRC signaling from a BS. When the UE is provided with DownlinkPreemption IE, the UE is configured with INT-RNTI provided by a parameter int-RNTI in DownlinkPreemption IE for monitoring of a PDCCH that conveys DCI format 2_1. The UE is additionally configured with a corresponding set of positions for fields in DCI format 2_1 according to a set of serving cells and positionInDCI by INT-ConfigurationPerServing Cell including a set of serving cell indexes provided by servingCellID, configured having an information payload size for DCI format 2_1 according to dci-Payloadsize, and configured with indication granularity of time-frequency resources according to timeFrequencySect.
The UE receives DCI format 2_1 from the BS on the basis of the DownlinkPreemption IE.
When the UE detects DCI format 2_1 for a serving cell in a configured set of serving cells, the UE can assume that there is no transmission to the UE in PRBs and symbols indicated by the DCI format 2_1 in a set of PRBs and a set of symbols in a last monitoring period before a monitoring period to which the DCI format 2_1 belongs. For example, the UE assumes that a signal in a time-frequency resource indicated according to preemption is not DL transmission scheduled therefor and decodes data on the basis of signals received in the remaining resource region.
E. mMTC (Massive MTC)
mMTC (massive Machine Type Communication) is one of 5G scenarios for supporting a hyper-connection service providing simultaneous communication with a large number of UEs. In this environment, a UE intermittently performs communication with a very low speed and mobility. Accordingly, a main goal of mMTC is operating a UE for a long time at a low cost. With respect to mMTC, 3GPP deals with MTC and NB (NarrowBand)-IoT.
mMTC has features such as repetitive transmission of a PDCCH, a PUCCH, a PDSCH (physical downlink shared channel), a PUSCH, etc., frequency hopping, retuning, and a guard period.
That is, a PUSCH (or a PUCCH (particularly, a long PUCCH) or a PRACH) including specific information and a PDSCH (or a PDCCH) including a response to the specific information are repeatedly transmitted. Repetitive transmission is performed through frequency hopping, and for repetitive transmission, (RF) returning from a first frequency resource to a second frequency resource is performed in a guard period and the specific information and the response to the specific information can be transmitted/received through a narrowband (e.g., 6 resource blocks (RBs) or 1 RB).
F. Basic Operation of AI Using 5G Communication
The UE transmits specific information to the 5G network (S1). The 5G network can perform 5G processing related to the specific information (S2). Here, the 5G processing can include AI processing. And the 5G network can transmit response including AI processing result to UE(S3).
G. Applied Operations Between UE and 5G Network in 5G Communication System
Hereinafter, the operation of an AI using 5G communication will be described in more detail with reference to wireless communication technology (BM procedure, URLLC, mMTC, etc.) described in
First, a basic procedure of an applied operation to which a method proposed by the present disclosure which will be described later and eMBB of 5G communication are applied will be described.
As in steps S1 and S3 of
More specifically, the UE performs an initial access procedure with the 5G network on the basis of an SSB in order to acquire DL synchronization and system information. A beam management (BM) procedure and a beam failure recovery procedure can be added in the initial access procedure, and quasi-co-location (QCL) relation can be added in a process in which the UE receives a signal from the 5G network.
In addition, the UE performs a random access procedure with the 5G network for UL synchronization acquisition and/or UL transmission. The 5G network can transmit, to the UE, a UL grant for scheduling transmission of specific information. Accordingly, the UE transmits the specific information to the 5G network on the basis of the UL grant. In addition, the 5G network transmits, to the UE, a DL grant for scheduling transmission of 5G processing results with respect to the specific information. Accordingly, the 5G network can transmit, to the UE, information (or a signal) related to remote control on the basis of the DL grant.
Next, a basic procedure of an applied operation to which a method proposed by the present disclosure which will be described later and URLLC of 5G communication are applied will be described.
As described above, an UE can receive DownlinkPreemption IE from the 5G network after the UE performs an initial access procedure and/or a random access procedure with the 5G network. Then, the UE receives DCI format 2_1 including a preemption indication from the 5G network on the basis of DownlinkPreemption IE. The UE does not perform (or expect or assume) reception of eMBB data in resources (PRBs and/or OFDM symbols) indicated by the preemption indication. Thereafter, when the UE needs to transmit specific information, the UE can receive a UL grant from the 5G network.
Next, a basic procedure of an applied operation to which a method proposed by the present disclosure which will be described later and mMTC of 5G communication are applied will be described.
Description will focus on parts in the steps of
In step S1 of
The above-described 5G communication technology can be combined with methods proposed in the present disclosure which will be described later and applied or can complement the methods proposed in the present disclosure to make technical features of the methods concrete and clear.

The output unit 150 generates an output related to sight, hearing, or tactile sense, and can include at least one of a display unit 151, an audio output unit 152, a haptic module 153, and a light output unit 154. The display unit 151 can form a mutual layer structure with the touch sensor or can be integrally formed with the touch sensor, thereby implementing a touch screen. The touch screen can provide an output interface between the mobile terminal 100 and the user while functioning as the user input unit 123 that provides an input interface between the mobile terminal 100 and the user.
The interface unit 160 serves as a path to various types of external devices connected to the mobile terminal 100.

In the mobile terminal 100, the appropriate control related to a connected external device can be performed according to the external device connected to the interface unit 160.
Further, the memory 170 stores data that support various functions of the mobile terminal 100. The memory 170 can store a plurality of application programs or applications driven in the mobile terminal 100, data for operating the mobile terminal 100, and instructions. At least some of these application programs can be downloaded from an external server through wireless communication. Further, at least some of these application programs can exist on the mobile terminal 100 from the time of launching for basic functions (e.g., a call receiving or transmitting function, a message receiving or transmitting function) of the mobile terminal 100. The application program can be stored in the memory 170, installed on the mobile terminal 100, and driven by the controller 180 to perform an operation (or function) of the mobile terminal.
In addition to the operation related to the application program, the controller 180 typically controls an overall operation of the mobile terminal 100. By processing signals, data, information, and the like, which are input or output through the above-described components or by driving an application program stored in the memory 170, the controller 180 can provide or process information or a function appropriate to a user.
Further, in order to drive an application program stored in the memory 170, the controller 180 can control at least some of the components described with reference to
The power supply unit 190 receives power from an external power source and an internal power source under the control of the controller 180 to supply power to each component included in the mobile terminal 100. The power supply unit 190 includes a battery, which can be a built-in battery or a replaceable battery.
In order to implement an operation, control, or control method of the mobile terminal according to various embodiments described below, at least some of the components can operate in cooperation with each other. Further, the operation, control, or control method of the mobile terminal can be implemented on the mobile terminal by driving at least one application program stored in the memory 170.
The display unit 151 displays (outputs) information processed by the mobile terminal 100. For example, the display unit 151 can display execution screen information of an application program driven in the mobile terminal 100 or user interface (UI) and graphical user interface (GUI) information according to the execution screen information.
The display unit 151 can include at least one of a liquid crystal display (LCD), a thin film transistor-liquid crystal display (TFT LCD), an organic light-emitting diode (OLED), a flexible display, a three-dimensional display (3D display), and an e-ink display.
Further, there can be two or more display units 151 according to an implementation form of the mobile terminal 100. In this case, in the mobile terminal 100, a plurality of display units can be separated at one surface or can be integrally disposed, and at different surfaces, each display unit can be disposed.
In order to receive a control command by a touch method, the display unit 151 can include a touch sensor that detects a touch on thereon. Using this, when a touch is performed on the display unit 151, the touch sensor can detect the touch, and the controller 180 can generate a control command corresponding to the touch based on the touch. The content input by the touch method can be texts or numbers or menu items that can be instructed or designated in various modes.
The touch sensor can be configured in a form of a film having a touch pattern and be disposed between a window and a display on a rear surface of the window or can be a metal wire directly patterned on the rear surface of the window. Alternatively, the touch sensor can be formed integrally with the display. For example, the touch sensor can be disposed on a substrate of the display or can be provided inside the display.
In this way, the display unit 151 can form a touch screen together with the touch sensor, and in this case, the touch screen can function as the user input unit 123. In some cases, the touch screen can replace at least some functions of a first manipulation unit.
The first sound output unit can be implemented into a receiver for transmitting a call sound to the user's ear, and the second sound output unit can be implemented in the form of a loud speaker that outputs various alarm sounds or reproduction sounds of multimedia.
A sound hole for emitting a sound generated from the first sound output unit can be formed in the window of the display unit 151. However, the present disclosure is not limited thereto, and the sound can be emitted along an assembly gap between the structures (e.g., a gap between the window and the front case). In this case, an independently formed hole for sound output can be externally invisible or hidden, thereby more simplifying an external shape of the mobile terminal 100.
The light output unit 154 can be configured to output light for notifying when an event occurs. Examples of the event can include message reception, call signal reception, missed call, alarm, schedule notification, email reception, information reception through an application, and the like. When the user's event check is detected, the controller 180 can control the light output unit 154 so as to end the light output.
The first camera processes an image frame of still pictures or moving pictures obtained by image sensors in an audiovisual call mode or a photographing mode. The processed image frames can be displayed on the display unit 151 and be stored in the memory 170.
The first to third manipulation units can be collectively referred to as a manipulating portion as an example of the user input unit 123 manipulated to receive a command for controlling an operation of the mobile terminal 100. The first to third manipulation units can be employed in any manner as long as the user manipulates with a tactile feeling such as touch, push, scroll, and the like. Further, the first and second manipulation units can be employed in such a manner that the first and second manipulation units operate without a tactile feeling of the user through a proximity touch, a hovering touch, or the like. The third manipulation unit can include a fingerprint recognition sensor to obtain a user's fingerprint. The obtained fingerprint information can be provided to the controller 180.
In the drawing, the first manipulation unit is illustrated as being a touch key, but the present disclosure is not limited thereto. For example, the first manipulation unit can be a mechanical key or can be configured with a combination of a touch key and a mechanical key.
The contents input by the first and second manipulation units can be variously set. For example, the first manipulation unit can receive a command such as a menu, a home key, a cancellation, a search, etc., and the second manipulation unit can receive adjustment in a volume of a sound output from the first or second sound output unit and a command such as switching to a touch recognition mode of the display unit 151.
As another example of the user input unit 123, a third manipulation unit can be provided at the rear surface of the terminal body. The third manipulation unit is manipulated to receive a command for controlling an operation of the mobile terminal 100, and the input content can be variously set.
For example, commands such as power on/off, start, end, and scrolling and commands such as adjustment in a volume of a sound output from the first and second sound output units, switching to a touch recognition mode of the display unit 151, and fingerprint information acquisition can be received. The rear input unit can be implemented in a form of a touch input, a push input, or an input by a combination thereof.
The rear input unit can be disposed to overlap with the front display unit 151 in a thickness direction of the terminal body. For example, the rear input unit can be disposed at the upper end of a rear surface of the terminal body so that the user can easily manipulate the terminal using an index finger when the user grips the terminal body with one hand. However, the present disclosure is not necessarily limited thereto, and a position of the rear input unit can be changed.
In this way, when the rear input unit is provided at the rear surface of the terminal body, a new type user interface using the rear input unit can be implemented. Further, when the above-described touch screen or rear input unit replaces at least some functions of the first manipulation unit provided in the front surface of the terminal body and the first manipulation unit is not disposed at the front surface of the terminal body, the display unit 151 can be configured in a larger surface.
The mobile terminal 100 can be provided with a fingerprint recognition sensor for recognizing a user's fingerprint, and the controller 180 can use fingerprint information detected through the fingerprint recognition sensor as an authentication means. The fingerprint recognition sensor can be embedded in the display unit 151 or the user input unit 123.
The microphone 122 can be configured to receive a user's voice, other sounds, and the like. The microphone 122 can be provided at a plurality of positions and be configured to receive a stereo sound.
The interface unit 160 serves as a path for connecting the mobile terminal 100 to an external device. For example, the interface unit 160 can be at least one of a connection terminal for connecting to another device (e.g., an earphone or an external speaker), a port (e.g., infrared port (IrDA Port), Bluetooth port, or a wireless LAN port) for short-range communication, or a power supply terminal for supplying power to the mobile terminal 100. The interface unit 160 can be implemented in the form of a socket for receiving an external card such as a subscriber identification module (SIM), a user identity module (UIM), or a memory card for storing information.
The second camera can be disposed at the rear surface of the terminal body. In this case, a second camera 121b has a photographing direction substantially opposite to that of the first camera.
The second camera can include a plurality of lenses arranged along at least one line. The plurality of lenses can be arranged in a matrix format. Such a camera can be referred to as an “array camera.” When the second camera is configured as an array camera, the plurality of lenses can be used to photograph images in various ways, and images of a better quality can be obtained.
A flash 124 can be disposed adjacent to the second camera. When a subject is photographed by the second camera, the flash 124 emits light toward the subject.
The second sound output unit can be additionally disposed in the terminal body. The second sound output unit can implement a stereo function together with the first sound output unit, and can be used for implementing a speakerphone mode during a call.
The terminal body can be provided with at least one antenna for wireless communication. The antenna can be built in the terminal body or can be formed in the case. For example, an antenna that forms part of the broadcast receiving module 111 (see
The terminal body is provided with the power supply unit 190 (see
The battery 191 can be configured to receive power through a power cable connected to the interface unit 160. Further, the battery 191 can be configured to enable wireless charging through a wireless charger. The wireless charging can be implemented by a magnetic induction method or a resonance method (magnetic resonance method).
Next, referring to
Then, the UE performs a random access procedure with the 5G network for UL synchronization acquisition and/or UL transmission (S41).
Then, the UE transmits the specific information to the 5G network based on a configured grant (S42). A procedure for configuring the grant in place of receiving the UL grant from the 5G network will be described in more detail below.
Then, the UE receives a DL grant for receiving a response to the specific information from the 5G network (S43).
Then, the UE receives the response including the AI processing result from the 5G network based on the DL grant (S44).
Referring to

The AI processor 21 is a computing device that can learn a neural network and can be implemented into various electronic devices such as a server, a desktop PC, a notebook PC, and a tablet PC.
The AI processor 21 can learn a neural network using a program stored in the memory 25. In particular, the AI processor 21 can learn a neural network for recognizing data related to the mobile terminal 100. Here, the neural network for recognizing data related to the mobile terminal 100 can be designed to simulate a human brain structure on a computer and include a plurality of network nodes having a weight and simulating a neuron of the human neural network. The plurality of network modes can give and receive data according to each connection relationship so as to simulate a synaptic activity of neurons that send and receive signals through a synapse. Here, the neural network can include a deep learning model developed in the neural network model. In the deep learning model, while a plurality of network nodes is positioned in different layers, the plurality of network nodes can send and receive data according to a convolution connection relationship. An example of the neural network model includes various deep learning techniques such as deep neural networks (DNN), convolutional deep neural networks (CNN), Recurrent Boltzmann Machine (RNN), Restricted Boltzmann Machine (RBM), deep belief networks (DBN), and a deep Q-network and can be applied to the field of computer vision, speech recognition, natural language processing, and voice/signal processing.
The processor for performing the above-described functions can be a general-purpose processor (e.g., central processing unit (CPU)), but can be an AI dedicated processor (e.g., graphics processing unit (GPU)) for learning AI.
The memory 25 can store various programs and data necessary for an operation of the AI device 200. The memory 25 can be implemented into a non-volatile memory, a volatile memory, a flash memory, a hard disk drive (HDD), or a solid state drive (SDD) and the like. The memory 25 can be accessed by the AI processor 21 and read/write/modify/delete/update of data can be performed by the AI processor 21. Further, the memory 25 can store a neural network model (e.g., a deep learning model 26) generated through learning algorithm for data classification/recognition according to an embodiment of the present disclosure.
The AI processor 21 can include a data learning unit 22 for learning a neural network for data classification/recognition. The data learning unit 22 can learn learning data to use in order to determine data classification/recognition and a criterion for classifying and recognizing data using learning data. By obtaining learning data to be used for learning and applying the obtained learning data to a deep learning model, the data learning unit 22 can learn a deep learning model.
The data learning unit 22 can be produced in at least one hardware chip form to be mounted in the AI device 200. For example, the data learning unit 22 can be produced in a dedicated hardware chip form for artificial intelligence (AI) and can be produced in a part of a general-purpose processor (e.g., CPU) or a graphic dedicated processor (e.g., GPU) to be mounted in the AI device 200. Further, the data learning unit 22 can be implemented into a software module. When the data learning unit 22 is implemented into a software module (or program module including an instruction), the software module can be stored in non-transitory computer readable media. In this case, at least one software module can be provided by an Operating System (OS) or can be provided by an application.
The data learning unit 22 can include a learning data acquisition unit 23 and a model learning unit 24.
The learning data acquisition unit 23 can obtain learning data necessary for a neural network model for classifying and recognizing data. For example, the learning data acquisition unit 23 can obtain data and/or sample data of the mobile terminal 100 for inputting as learning data to the neural network model.
The model learning unit 24 can learn to have a determination criterion in which a neural network model classifies predetermined data using the obtained learning data. In this case, the model learning unit 24 can learn a neural network model through supervised learning that uses at least a portion of the learning data as a determination criterion. Alternatively, the model learning unit 24 can learn the neural network model through unsupervised learning that finds a determination criterion by self-learning using learning data without supervision. Further, the model learning unit 24 can learn the neural network model through reinforcement learning using feedback on whether a result of situation determination according to learning is correct. Further, the model learning unit 24 can learn the neural network model using learning algorithm including error back-propagation or gradient decent.
When the neural network model is learned, the model learning unit 24 can store the learned neural network model in the memory. The model learning unit 24 can store the learned neural network model at the memory of the server connected to the AI device 200 by a wired or wireless network.
In order to improve an analysis result of a recognition model or to save a resource or a time necessary for generation of the recognition model, the data learning unit 22 can further include a learning data pre-processor and a learning data selecting unit.
The learning data pre-processor can pre-process obtained data so that the obtained data can be used in learning for situation determination. For example, the learning data pre-processor can process the obtained data in a predetermined format so that the model learning unit 24 uses obtained learning data for learning for image recognition.
Further, the learning data selection unit can select data necessary for learning among learning data obtained from the learning data acquisition unit 23 or learning data pre-processed in the pre-processor. The selected learning data can be provided to the model learning unit 24. For example, by detecting a specific area of an image obtained through a camera of the mobile terminal 100, the learning data selection unit can select only data of an object included in the specified area as learning data.
Further, in order to improve an analysis result of the neural network model, the data learning unit 22 can further include a model evaluation unit.
The model evaluation unit inputs evaluation data to the neural network model, and when an analysis result output from evaluation data does not satisfy predetermined criteria, the model evaluation unit can enable the model learning unit 24 to learn again. In this case, the evaluation data can be data previously defined for evaluating a recognition model. For example, when the number or a proportion of evaluation data having inaccurate analysis results exceeds a predetermined threshold value among analysis results of a learned recognition model of evaluation data, the model evaluation unit can evaluate evaluation data as data that do not satisfy predetermined criteria.
The communication unit 27 can transmit an AI processing result by the AI processor 21 to an external electronic device.
It has been described that the AI device 200 of
Recently, with the development of information and communication technology, diversification and functions of smartphones have been much improved. Accordingly, spread of smartphones has been rapidly progressed, and more than one smartphone per person is being distributed.
With the spread of smartphones, in a specific situation, a situation has occurred in which notification providing is required through a notification setting appropriate to the situation, and there has been inconvenience in that a user should change a notification setting each time in a specific situation for an appropriate notification setting and there was a problem that a case occurs in which the user does not change the notification setting by an error.
In the present specification, in order to solve the above-described inconvenience and problem, a method is proposed in which the smartphone recognizes a surrounding situation to provide a notification through notification setting appropriate to the surrounding situation.
Hereinafter, the smartphone described in the present specification can be used interchangeably with the terminal.
Referring to
The smartphone can recognize a surrounding situation based on the detection result of such a situation. In this case, in order to recognize the surrounding situation, the smartphone can detect a sound, an image, a position, an external signal, and the like through a plurality of sensors installed therein and recognize the surrounding situation through the detected result.
In other words, the smartphone can recognize/identify a surrounding situation of a position in which the smartphone is currently positioned based on the detected surrounding situation using a plurality of sensors.
For example, when a smartphone detects a movie screen, a plurality of seats, a plurality of people, a dark environment, etc. using a plurality of sensors, the smartphone can recognize that the current situation is inside a movie theater.
As another example, when the smartphone detects a plurality of books using a plurality of sensors and detects a very small sound or cannot detect ambient noise, the smartphone can recognize that the current situation is inside the library.
Thereafter, the smartphone can change the notification setting of the smartphone based on a preset notification setting and provide a notification according to the changed notification setting.
In this case, the notification setting can include one or more of silence, a vibration, a smart watch notification, always on display (AOD), minimum brightness, and high contrast screen.
For example, when the smartphone recognizes that the current surrounding situation is inside the library, the inside of the library is sensitive to noise and thus silence or a vibration notification can be set.
Further, when the smartphone recognizes that the current surrounding situation is inside a movie theater, at the inside of the movie theater, the smartphone is sensitive to brightness at a position other than the screen and is sensitive to ambient noise and thus silence or a vibration notification can be set and a minimum brightness setting can be additionally performed.
Therefore, the smartphone recognizes a surrounding situation by itself and sets a notification operation mode, thereby enabling the user to observe the rules of etiquette by setting the notification operation mode so as not to disturb the surroundings.
Hereinafter, a method in which information collection for recognizing a surrounding situation is performed through the sensor unit will be described with reference to
Various sensors built into the smartphone can be used for detecting a surrounding situation of a position in which the smartphone is positioned. The surrounding situation can be recognized based on the detected surrounding situation.
In consideration of the recognized surrounding situation, a notification setting to provide a notification can be determined.
In this case, a detection object to be detected by various sensors will be described.
The sensor installed in the smartphone can detect position information, and when the smartphone is positioned at a periphery of a specific place through the detected position information, the smartphone can provide a notification setting appropriate to the specific place. In this case, the position information can periodically, i.e., at specific time intervals detect position (place) information and recognize a surrounding environment.
Further, by collecting/detecting position information and payment information related to a current time, the sensor installed in the smartphone can recognize a surrounding environment.
For example, the smartphone can detect payment information in which a user of the smartphone paid a movie ticket at a movie theater and compare a present time and position information with a movie running time, movie theater (place), etc. included in the payment information to recognize that a surrounding environment, i.e., the user of the smartphone is inside the movie theater. Additionally, in order to determine whether the user is inside a movie theater, the smartphone can use a sensor for detecting a sound and/or a sensor for detecting an image.
For example, by recognizing a position of a current user (smartphone) by comparing payment information with a current time and position information, the smartphone can additionally recognize a more accurate position (surrounding situation) of a user (smartphone) using a sensor for detecting a sound and/or a sensor for detecting an image.
Further, the sensor installed in the smartphone can detect schedule information input by the user with an application installed in the smartphone to identify position information and recognize a current surrounding situation.
For example, when the user inputs information about a specific day of the week, a specific time, and a specific place as a schedule, the sensor installed in the smartphone can recognize a current surrounding situation in consideration of the schedule information, the time information, the day of the week information, etc. in a comprehensive manner. Specifically, when the user inputs a schedule such as “room 1 at 3 pm on Jul. 26, 2019” to a smartphone application for a meeting, the smartphone can identify the schedule information and change to the preset notification setting at 3 pm on Jul. 26, 2019. Further, additionally, in order to determine whether the user is actually positioned in a conference room at a designated time (3 pm on Jul. 26, 2019), the smartphone can additionally use a sensor for detecting a sound and/or a sensor for detecting an image.
For example, it can be determined whether a meeting is currently in progress using a sensor for detecting a sound, and it can be additionally determined whether a position is a conference room through a sensor for detecting an image. In this case, when it is determined that the user is not in a conference room, the smartphone can maintain an existing notification setting without changing.
Further, by detecting/collecting information of a Social Network Service (SNS) post related to a user account of the smartphone, the sensor installed in the smartphone can recognize a current surrounding situation.
For example, when the user of the smartphone uploads a post such as “Watching a movie at 2 pm on Jul. 27, 2019,” on an SNS, the smartphone can detect this and change a notification setting to a preset notification corresponding to a movie theater at “2 pm on Jul. 27, 2019.”
In this case, in order to additionally determine whether the user is positioned in a movie theater, a sensor for detecting a sound and/or a sensor for detecting an image can be used and a detailed description thereof is described as described above.
Further, the sensor installed in the smartphone can detect sound information, and the detected sound information can be classified into and detected to noise, space, and sound kind.
For example, it can be distinguished whether the detected sound is a sound detected in a closed space or a sound detected in an open space, and it can be distinguished whether the detected sound is an animal sound, a wind sound, or a human sound.
In this case, in order to distinguish the detected sound information into noise, space, and sound type, Deep Neural Network (DNN) learning can be used and only valid information can be extracted from the detected sound through the DNN learning and thus a sound can be distinguished.
Further, the sensor installed in the smartphone can detect image information, and identify and recognize brightness, a color, an object, and a place in the detected image.
DNN learning (e.g., see
Further, in order to detect the above-described position information, a GPS sensor can be used, and sensors can be triggered through position information and time information based on the GPS sensor.
Referring to
In this case, the detected information and information on the recognized surrounding situation can be fed back and stored in a smartphone internal device.
That is, the result of the detected information and the recognized surrounding situation can be added to a separate inference model in the form of feedback, and accuracy can be improved by learning the inference model.
In this case, the above DNN learning can be used as a learning method.
Therefore, there is an effect that an optimal notification setting is possible for each surrounding situation/environment.
For example, by inputting all information collected through a plurality of sensors, the smartphone can recognize and identify a current place and a surrounding situation.
The notification setting can be available according to the recognized surrounding situation. Table 1 shows an example of setting a notification considering the surrounding situation.
Referring to Table 1, when a surrounding situation of a current position of a smartphone is recognized as a movie theater using information detected using a plurality of sensors, a sound can be set to silence, a vibration notification can be set, screen brightness can be set to a minimum, and a screen can be set to a high contrast inversion mode. In this case, an always on display (AOD) screen mode can be used, and when a smartphone user is using a wearable device, the vibration notification setting can be set and applied only to the wearable device.
For example, when the user of the smartphone checks a notification of the smartphone while watching a movie, screen brightness can be set to a minimum and the smartphone can display a screen in a high contrast mode to enable the user to check the notification.
Further, when a surrounding situation of a current position of the smartphone is recognized as a library, a sound can be set to silence, a vibration may not be set or can be set to weakest vibration intensity, and screen brightness may not be adjusted and a screen may not be also adjusted. In this case, similarly, when the user of the smartphone is using a wearable device, a vibration setting can be set only to the wearable device.
Table 1 shows an example of a notification setting, and a notification setting appropriate to various surrounding situations can be defined.
The deep neural network (DNN) shown in

In this case, the terminal obtains second information through a plurality of sensors (S720).
The terminal recognizes a surrounding situation based on the first information and the second information (S730).
The terminal provides a notification according to a preset notification setting based on the recognized surrounding situation (S740).
The first information can include at least one of information about a specific time and information about a specific position, and the second information can include at least one of position information, sound information, image information, and external signal information.
In this case, the plurality of sensors can be a sensor for detecting at least one of the position information, sound information, image information, and the external signal information.
In this case, the preset notification setting of S740 can include at least one of a sound notification related setting, a screen brightness related setting, a vibration notification related setting, and a screen operation related setting. As shown in Table 1, the preset notification setting can be set in advance according to the surrounding situation, and the smartphone can recognize a surrounding situation detected by the plurality of sensors and provide a preset notification.
Further, the terminal can store the recognized surrounding situation information, and in this case, the preset notification setting can determine the stored recognized surrounding situation information by deep neural network (DNN) learning. In order to more accurately recognize the surrounding situation, the terminal can add a surrounding situation recognized using the surrounding situation detected through the plurality of sensors to a separate inference model in the form of feedback and learn the inference model to improve accuracy.
In this case, the vibration notification related setting can be applied to a wearable device.
Further, the screen operation related setting can be a setting related to an always on display (AOD) or a high contrast screen.
When the second information includes the sound information or the image information, valid information can be extracted through DNN learning of the sound information or the image information, and the recognized surrounding situation can be determined based on the valid information.

In this case, the preset notification setting can be set for each surrounding situation as shown in Table 1.
The storage unit 880 can store surrounding situation information recognized by the sensor unit 810. In this case, the preset notification setting can be determined by learning DNN of the surrounding situation information stored through the storage unit 880, and thus an optimum notification setting appropriate to each surrounding situation can be provided.
