Description

Technical Field

[0001] The present disclosure relates to an electronic device for receiving a paging message and an operating method thereof. Background Art

[0002] Efforts are underway to develop improved fifth-generation (5G) communication systems, or pre-5G communication systems, to meet the growing demand for wireless data services following the commercialization of fourth-generation (4G) communication systems. For this purpose, 5G communication systems, or pre-5G communication systems, are referred to as beyond-4G network communication systems or post-Long Term Evolution (post-LTE) systems.

[0003] To achieve high data transmission rates, 5G communication systems are being considered for implementation in very high frequency (millimeter wave) bands, such as the 60 GHz band. To reduce radio wave path loss and increase the propagation distance of radio waves in the very high frequency band, beamforming, massive MIMO, full-dimensional MIMO (FD-MIMO), array antennas, analog beamforming, and massive antenna technologies are being discussed in 5G communication systems.

[0004] 5G-enabled electronic devices can use discontinuous reception (DRX) in the RRC_INACTIVE state or the RRC_IDLE state to reduce battery consumption. The electronic device can monitor one paging opportunity (PO) for each DRX cycle (or paging cycle). The electronic device can wake up during at least a portion of the PO to monitor the physical downlink control channel (PDCCH) and can remain in a sleep state (or inactive state) during the remaining opportunities, thereby reducing battery consumption and / or resource consumption.

[0005] In a multi-beam environment, the network needs to send a paging message for each of the multiple beam indices. For example, when the electronic device is in DRX mode, the network may not be able to identify which beam index the electronic device has selected. The network can send a paging message for each beam index in each of the multiple time slots in a PO.

[0006] There is no recommendation on which paging message an electronic device must select when a paging message is sent in each of multiple time slots. The Third Generation Partnership Project (3GPP) Technical Specification (TS) 38.304 stipulates that in a multi-beam environment, the user equipment assumes that the same paging message and the same short message are repeated in all transmitted beams, and the selection of beams for receiving paging messages and short messages depends on the implementation of the user equipment. Summary of the Invention

[0007] Embodiments of the present disclosure may determine a time slot in which monitoring is to be performed in a current period based on signal strength measured in a previous period.

[0008] According to an example embodiment, an electronic device may include: a memory; a communication module; and at least one processor, wherein the at least one processor is configured to: receive a plurality of synchronization signal (SS) / physical broadcast channel (PBCH) blocks (SSBs) from a network via the communication module, identify a plurality of time slots corresponding to the plurality of SSBs, respectively, select at least one time slot to be monitored in a current period based on a measurement result of a signal measured in at least one of the plurality of time slots in a previous period in a discontinuous reception (DRX) mode, and wake up and monitor a physical downlink control channel (PDCCH) in the selected at least one time slot.

[0009] According to an example embodiment, an electronic device may include: a memory; a communication module; and at least one processor, wherein the at least one processor is configured to receive a plurality of synchronization signal (SS) / physical broadcast channel (PBCH) blocks (SSBs) from a network via the communication module, identify a plurality of time slots corresponding to the plurality of SSBs, respectively, select at least one time slot to be monitored in a current period based on information associated with movement of the electronic device in a discontinuous reception (DRX) mode, wake up in the selected at least one PDCCH monitoring opportunity, and monitor a physical downlink control channel (PDCCH).

[0010] According to an example embodiment, a method of operating an electronic device may include: receiving a plurality of synchronization signal (SS) / physical broadcast channel (PBCH) blocks (SSBs) from a network; identifying a plurality of time slots corresponding to the plurality of SSBs, respectively; selecting at least one time slot to be monitored in a current period based on a measurement result of a signal measured in at least one of the plurality of time slots in a previous period in a discontinuous reception (DRX) mode; and waking up and monitoring a physical downlink control channel (PDCCH) in the selected at least one time slot.

[0011] According to an example embodiment, a method of operating an electronic device may include: receiving a plurality of synchronization signal (SS) / physical broadcast channel (PBCH) blocks (SSBs) from a network; identifying a plurality of time slots corresponding to the plurality of SSBs, respectively; selecting at least one time slot in which to perform monitoring in a current period based on information associated with movement of the electronic device in a discontinuous reception (DRX) mode; and waking up in at least one selected physical downlink control channel (PDCCH) monitoring opportunity and monitoring the PDCCH.

[0012] Example embodiments may provide an electronic device and an operating method thereof, wherein the electronic device is capable of determining a time slot to perform monitoring in a current time slot based on the strength of a signal measured in a previous time slot. Therefore, the electronic device may not wake up in all time slots to perform monitoring, thereby saving power and / or resources. BRIEF DESCRIPTION OF THE DRAWINGS

Figure 1 , the electronic device 101 in the network environment 100 can communicate with the electronic device 102 via the first network 198 (e.g., a short-range wireless communication network), or can communicate with at least one of the electronic device 104 or the server 108 via the second network 199 (e.g., a long-range wireless communication network). According to an embodiment, the electronic device 101 can communicate with the electronic device 104 via the server 108. According to an embodiment, the electronic device 101 may include a processor 120, a memory 130, an input module 150, a sound output module 155, a display module 160, an audio module 170, a sensor module 176, an interface 177, a connection terminal 178, a haptic module 179, a camera module 180, a power management module 188, a battery 189, a communication module 190, a subscriber identification module (SIM) 196, or an antenna module 197. In an embodiment, at least one of the above components (e.g., the connection terminal 178) may be omitted from the electronic device 101, or one or more other components may be added to the electronic device 101. In embodiments, some of the above-described components (eg, sensor module 176, camera module 180, or antenna module 197) may be implemented as a single integrated component (eg, display module 160).

[0034] The processor 120 may run, for example, software (e.g., program 140) to control at least one other component of the electronic device 101 connected to the processor 120 (e.g., a hardware component or a software component), and may perform various data processing or calculations. According to an embodiment, as at least part of the data processing or calculation, the processor 120 may store a command or data received from another component (e.g., the sensor module 176 or the communication module 190) in the volatile memory 132, process the command or data stored in the volatile memory 132, and store the resultant data in the non-volatile memory 134. According to an embodiment, the processor 120 may include a main processor 121 (e.g., a central processing unit (CPU) or an application processor (AP)) or an auxiliary processor 123 (e.g., a graphics processing unit (GPU), a neural processing unit (NPU), an image signal processor (ISP), a sensor hub processor, or a communication processor (CP)) that is operationally independent of or combined with the main processor 121. For example, when the electronic device 101 includes a main processor 121 and an auxiliary processor 123, the auxiliary processor 123 may be adapted to consume less power than the main processor 121 or be adapted to be dedicated to a specific function. The auxiliary processor 123 may be implemented separately from the main processor 121 or as part of the main processor 121.

[0035] When the main processor 121 is inactive (e.g., sleeping), the auxiliary processor 123 (rather than the main processor 121) may control at least some of the functions or states associated with at least one of the components of the electronic device 101 (e.g., the display module 160, the sensor module 176, or the communication module 190). Alternatively, when the main processor 121 is active (e.g., running an application), the auxiliary processor 123 may work together with the main processor 121 to control at least some of the functions or states associated with at least one of the components of the electronic device 101 (e.g., the display module 160, the sensor module 176, or the communication module 190). Depending on the embodiment, the auxiliary processor 123 (e.g., an image signal processor or a communication processor) may be implemented as part of another component functionally related to the auxiliary processor 123 (e.g., the camera module 180 or the communication module 190). Depending on the embodiment, the auxiliary processor 123 (e.g., a neural processing unit) may include a hardware structure dedicated to artificial intelligence model processing. The artificial intelligence model may be generated through machine learning. For example, such learning may be performed by the electronic device 101 where the artificial intelligence is executed or via a separate server (e.g., server 108). The learning algorithm may include, but is not limited to, supervised learning, unsupervised learning, semi-supervised learning, or reinforcement learning. The artificial intelligence model may include multiple artificial neural network layers. The artificial neural network may be a deep neural network (DNN), a convolutional neural network (CNN), a recurrent neural network (RNN), a restricted Boltzmann machine (RBM), a deep belief network (DBN), a bidirectional recurrent deep neural network (BRDNN), or a deep Q network or a combination of two or more thereof, but is not limited thereto. Additionally or alternatively, the artificial intelligence model may include a software structure in addition to a hardware structure.

The various data may include, for example, software (e.g., the program 140) and input data or output data for commands related thereto. The memory 130 may include a volatile memory 132 or a non-volatile memory 134.

[0037] The program 140 may be stored as software in the memory 130 , and may include, for example, an operating system (OS) 142 , middleware 144 , or applications 146 .

[0038] The input module 150 may receive commands or data from outside the electronic device 101 (e.g., a user) to be used by other components of the electronic device 101 (e.g., the processor 120). The input module 150 may include, for example, a microphone, a mouse, a keyboard, keys (e.g., buttons), or a digital pen (e.g., a stylus).

[0039] The sound output module 155 can output sound signals to the outside of the electronic device 101. The sound output module 155 may include, for example, a speaker or a receiver. The speaker can be used for general purposes such as playing multimedia or playing records. The receiver can be used to receive incoming calls. Depending on the embodiment, the receiver can be implemented separately from the speaker or as part of the speaker.

The display module 160 may include, for example, a display, a holographic device, or a projector, and a control circuit for controlling a corresponding one of the display, the holographic device, and the projector. Depending on the embodiment, the display module 160 may include a touch sensor adapted to detect a touch or a pressure sensor adapted to measure the strength of the force caused by the touch.

[0041] The audio module 170 can convert sound into an electrical signal, and vice versa. According to an embodiment, the audio module 170 can obtain sound via the input module 150, or output sound via the sound output module 155 or an earphone of an external electronic device (e.g., electronic device 102) directly (e.g., wired) or wirelessly connected to the electronic device 101.

[0042] The sensor module 176 can detect an operating state (e.g., power or temperature) of the electronic device 101 or an environmental state (e.g., a user's state) outside the electronic device 101, and then generate an electrical signal or data value corresponding to the detected state. Depending on the embodiment, the sensor module 176 may include, for example, a gesture sensor, a gyro sensor, an atmospheric pressure sensor, a magnetic sensor, an acceleration sensor, a grip sensor, a proximity sensor, a color sensor, an infrared (IR) sensor, a biometric sensor, a temperature sensor, a humidity sensor, or an illumination sensor.

[0043] The interface 177 may support one or more specific protocols to be used to connect the electronic device 101 directly (e.g., wired) or wirelessly to an external electronic device (e.g., the electronic device 102). Depending on the embodiment, the interface 177 may include, for example, a High-Definition Multimedia Interface (HDMI), a Universal Serial Bus (USB) interface, a Secure Digital (SD) card interface, or an audio interface.

[0044] The connection end 178 may include a connector, wherein the electronic device 101 can be physically connected to an external electronic device (e.g., the electronic device 102) via the connector. Depending on the embodiment, the connection end 178 may include, for example, an HDMI connector, a USB connector, an SD card connector, or an audio connector (e.g., a headphone connector).

[0045] The haptic module 179 may convert the electrical signal into mechanical stimulation (eg, vibration or motion) or electrical stimulation that can be recognized by the user via his sense of touch or kinesthetic sense. According to an embodiment, the haptic module 179 may include, for example, a motor, a piezoelectric element, or an electrical stimulator.

[0046] The camera module 180 may capture still images or moving images. Depending on the embodiment, the camera module 180 may include one or more lenses, image sensors, image signal processors, or flashes.

[0047] The power management module 188 may manage power supply to the electronic device 101. According to an embodiment, the power management module 188 may be implemented as, for example, at least a part of a power management integrated circuit (PMIC).

[0048] The battery 189 may power at least one component of the electronic device 101. According to an embodiment, the battery 189 may include, for example, a non-rechargeable primary battery, a rechargeable secondary battery, or a fuel cell.

[0049] The communication module 190 may support establishing a direct (e.g., wired) communication channel or a wireless communication channel between the electronic device 101 and an external electronic device (e.g., electronic device 102, electronic device 104, or server 108), and perform communication via the established communication channel. The communication module 190 may include one or more communication processors capable of operating independently from the processor 120 (e.g., application processor (AP)) and support direct (e.g., wired) communication or wireless communication. According to an embodiment, the communication module 190 may include a wireless communication module 192 (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module 194 (e.g., a local area network (LAN) communication module or a power line communication (PLC) module). A corresponding one of these communication modules may communicate via a first network 198 (e.g., a short-range communication network such as Bluetooth TM , Wireless Fidelity (Wi-Fi) Direct, or Infrared Data Association (IrDA)) or a second network 199 (for example, a long-distance communication network such as a traditional cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (for example, a LAN or a wide area network (WAN)))). These various types of communication modules may be implemented as a single component (for example, a single chip), or may be implemented as multiple components separated from each other (for example, multiple chips). The wireless communication module 192 may identify and authenticate the electronic device 101 in a communication network (such as the first network 198 or the second network 199) using user information (for example, an International Mobile Subscriber Identity (IMSI)) stored in the user identification module 196.

[0050] The wireless communication module 192 can support 5G networks after 4G networks and next-generation communication technologies (e.g., new radio (NR) access technology). NR access technology can support enhanced mobile broadband (eMBB), massive machine type communication (mMTC), or ultra-reliable low-latency communication (URLLC). The wireless communication module 192 can support high-frequency bands (e.g., millimeter wave bands) to achieve, for example, high data transmission rates. The wireless communication module 192 can support various technologies for ensuring performance on high-frequency bands, such as, for example, beamforming, massive multiple-input multiple-output (massive MIMO), full-dimensional MIMO (FD-MIMO), array antennas, analog beamforming, or massive antennas. The wireless communication module 192 can support various requirements specified in the electronic device 101, an external electronic device (e.g., electronic device 104), or a network system (e.g., a second network 199). According to an embodiment, the wireless communication module 192 may support peak data rates for implementing eMBB (e.g., 20 Gbps or greater), loss coverage for implementing mMTC (e.g., 164 dB or less), or U-plane latency for implementing URLLC (e.g., 0.5 ms or less for each of the downlink (DL) and uplink (UL), or 1 ms or less round trip).

[0051] Antenna module 197 can transmit or receive signals or power to or from the outside of electronic device 101 (e.g., an external electronic device). Depending on the embodiment, antenna module 197 may include an antenna comprising a radiating element formed of a conductive material or conductive pattern formed in or on a substrate (e.g., a printed circuit board (PCB)). Depending on the embodiment, antenna module 197 may include multiple antennas (e.g., an array antenna). In this case, at least one antenna suitable for the communication scheme used in a communication network (such as first network 198 or second network 199) may be selected from the multiple antennas by, for example, communication module 190 (e.g., wireless communication module 192). Signals or power can then be transmitted or received between communication module 190 and the external electronic device via the selected at least one antenna. Depending on the embodiment, additional components other than the radiating element (e.g., a radio frequency integrated circuit (RFIC)) may also be formed as part of antenna module 197.

[0052] According to an embodiment, antenna module 197 may form a millimeter wave antenna module. According to an embodiment, the millimeter wave antenna module may include a printed circuit board, a radio frequency integrated circuit (RFIC), and a plurality of antennas (e.g., array antennas), wherein the RFIC is disposed on a first surface (e.g., the bottom surface) of the printed circuit board, or adjacent to the first surface and capable of supporting a specified high frequency band (e.g., the millimeter wave band), and the plurality of antennas are disposed on a second surface (e.g., the top surface or the side surface) of the printed circuit board, or adjacent to the second surface and capable of transmitting or receiving signals in the specified high frequency band.

[0053] At least some of the above components can be connected to each other via an inter-peripheral communication scheme (e.g., a bus, general-purpose input output (GPIO), serial peripheral interface (SPI), or mobile industry processor interface (MIPI)) and communicatively transmit signals (e.g., commands or data) therebetween.

[0054] According to an embodiment, commands or data may be transmitted or received between the electronic device 101 and the external electronic device 104 via the server 108 connected to the second network 199. Each of the electronic device 102 or the electronic device 104 may be a device of the same type as the electronic device 101, or a device of a different type than the electronic device 101. According to an embodiment, all or some operations to be executed on the electronic device 101 may be executed on one or more of the external electronic device 102, the external electronic device 104, or the server 108. For example, if the electronic device 101 should automatically execute a function or service or should execute a function or service in response to a request from a user or another device, the electronic device 101 may request the one or more external electronic devices to execute at least part of the function or service instead of executing the function or service, or the electronic device 101 may request the one or more external electronic devices to execute at least part of the function or service in addition to executing the function or service. The one or more external electronic devices that receive the request may execute at least part of the function or service requested, or execute another function or service related to the request, and transmit the result of the execution to the electronic device 101. The electronic device 101 may provide the result as at least a partial reply to the request, with or without further processing the result. To this end, cloud computing technology, distributed computing technology, mobile edge computing (MEC) technology, or client-server computing technology, for example, may be used. The electronic device 101 may use, for example, distributed computing or mobile edge computing to provide ultra-low latency services. In an embodiment, the external electronic device 104 may include an Internet of Things (IoT) device. The server 108 may be an intelligent server using machine learning and / or neural networks. According to an embodiment, the external electronic device 104 or the server 108 may be included in the second network 199. The electronic device 101 may be applied to intelligent services (e.g., smart homes, smart cities, smart cars, or healthcare) based on 5G communication technology or IoT-related technologies.

[0055] Figure 2A 2 is a block diagram illustrating an example configuration of an electronic device 101 for supporting network communication and 5G network communication according to an embodiment. Figure 2A, the electronic device 101 may include a first communication processor (e.g., including a processing circuit) 212, a second communication processor (e.g., including a processing circuit) 214, a first radio frequency integrated circuit (RFIC) 222, a second RFIC 224, a third RFIC 226, a fourth RFIC 228, a first radio frequency front end (RFFE) 232, a second RFFE 234, a first antenna module (e.g., including at least one antenna) 242, a second antenna module (e.g., including at least one antenna) 244, a third antenna module (e.g., including at least one antenna) 246, and an antenna 248. The electronic device 101 may further include a processor (e.g., including a processing circuit) 120 and a memory 130. The second network 199 may include a first network 292 and a second network 294. According to an embodiment, the electronic device 101 may further include Figure 1 The first communication processor 212, the second communication processor 214, the first RFIC 222, the second RFIC 224, the fourth RFIC 228, the first RFFE 232, and the second RFFE 234 may form at least a portion of the wireless communication module 192. Depending on the embodiment, the fourth RFIC 228 may be omitted or may be included as part of the third RFIC 226.

[0056] The first communication processor 212 may include various processing circuits and establish a communication channel for a frequency band used for wireless communication with the first network 292, and may support traditional network communication through the established communication channel. According to an embodiment, the first network may be a traditional network, including a 2G, 3G, 4G or long term evolution (LTE) network. The second communication processor 214 may include various processing circuits and establish a communication channel corresponding to a specified frequency band (e.g., from about 6 GHz to about 60 GHz) in the frequency band to be used for wireless communication with the second network 294, and may support 5G network communication through the established communication channel. According to an embodiment, the second network 294 may be a 5G network defined in 3GPP. In addition, according to an embodiment, the first communication processor 212 or the second communication processor 214 may establish a communication channel corresponding to another specified frequency band (e.g., about 6 GHz or lower) in the frequency band to be used for wireless communication with the second network 294, and may support 5G network communication through the established communication channel.

[0057] The first communication processor 212 may transmit and receive data to and from the second communication processor 214. For example, data that has been classified as being transmitted through the second cellular network 294 may be transmitted through the first cellular network 292. In this case, the first communication processor 212 may receive transmission data from the second communication processor 214.

[0058] For example, the first communication processor 212 can transmit and receive data to and from the second communication processor 214 through the inter-processor interface 213. The inter-processor interface 213 can be implemented as, for example, a universal asynchronous receiver / transmitter (UART) (e.g., a high-speed UART (HS-UART) or a peripheral component interconnect express (PCIe) interface), but its type is not limited. Alternatively, the first communication processor 212 and the second communication processor 214 can exchange control information and packet data information using, for example, a shared memory. The first communication processor 212 can transmit and receive various types of information, such as sensing information, information about output strength, and resource block (RB) allocation information, to and from the second communication processor 214.

[0059] Depending on the implementation, the first communication processor 212 may not be directly connected to the second communication processor 214. In this case, the first communication processor 212 can send data to the second communication processor 214 and receive data from the second communication processor 214 through the processor 120 (e.g., application processor). For example, the first communication processor 212 and the second communication processor 214 can send data to the processor 120 (e.g., application processor) and receive data from the processor 120 through an HS-UART interface or a PCIe interface, but the type of interface is not limited. Alternatively, the first communication processor 212 and the second communication processor 214 can use a shared memory to exchange control information and packet data information with the processor 120 (e.g., application processor).

[0060] According to an embodiment, the first communication processor 212 and the second communication processor 214 may be implemented in a single chip or a single package. According to an embodiment, the first communication processor 212 or the second communication processor 214 may be arranged in a single chip or a single package together with the processor 120, the auxiliary processor 123 or the communication module 190. For example, Figure 2B As shown, the integrated communication processor 260 may support the functionality of communicating with both a first cellular network 292 and a second cellular network 294 .

[0061] During transmission, the first RFIC 222 may convert the baseband signal generated by the first communication processor 212 into a radio frequency (RF) signal of approximately 700 MHz to approximately 3 GHz for the first network 292 (e.g., a legacy network). During reception, the RF signal may be acquired from the first network 292 (e.g., a legacy network) via an antenna (e.g., the first antenna module 242) and may be pre-processed by an RFFE (e.g., the first RFFE 232). The first RFIC 222 may convert the pre-processed RF signal into a baseband signal that can be processed by the first communication processor 212.

[0062] During transmission, the second RFIC 224 can convert the baseband signal generated by the first communication processor 212 or the second communication processor 214 into an RF signal in the Sub-6 frequency band (e.g., approximately 6 GHz or lower) for the second network 294 (e.g., a 5G network) (hereinafter referred to as a 5G Sub-6 RF signal). During reception, the 5G Sub-6 RF signal can be obtained from the second network 294 (e.g., a 5G network) via an antenna (e.g., the second antenna module 244) and can be pre-processed by the RFFE (e.g., the second RFFE 234). The second RFIC 224 can convert the pre-processed 5G Sub-6 RF signal into a baseband signal, which can be processed by the corresponding communication processor of the first communication processor 212 or the second communication processor 214.

[0063] The third RFIC 226 may convert the baseband signal generated by the second communication processor 214 into an RF signal (hereinafter referred to as a 5G Above 6 RF signal) in the 5G Above 6 frequency band (e.g., from about 6 GHz to about 60 GHz) to be used in the second network 294 (e.g., a 5G network). During reception, the 5G Above 6 RF signal may be acquired from the second network 294 (e.g., a 5G network) via an antenna (e.g., antenna 248) and may be pre-processed by the third RFFE 236. The third RFIC 226 may convert the pre-processed 5G Above 6 RF signal into a baseband signal that can be processed by the second communication processor 214. According to an embodiment, the third RFFE 236 may be formed as part of the third RFIC 226.

[0064] According to an embodiment, the electronic device 101 may include a fourth RFIC 228 that is separate from or at least part of the third RFIC 226. The fourth RFIC 228 may convert the baseband signal generated by the second communication processor 214 into an RF signal (hereinafter referred to as an IF signal) in an intermediate frequency band (e.g., from about 9 GHz to about 11 GHz), and then transmit the IF signal to the third RFIC 226. The third RFIC 226 may convert the IF signal into a 5G Above 6 RF signal. Upon reception, the 5G Above 6 RF signal may be received from the second network 294 (e.g., a 5G network) via an antenna (e.g., antenna 248) and may be converted into an IF signal by the third RFIC 226. The fourth RFIC 228 may convert the IF signal into a baseband signal that can be processed by the second communication processor 214.

[0065] According to an embodiment, the first RFIC 222 and the second RFIC 224 may be implemented as at least part of a single package or a single chip. Figure 2A or Figure 2B When the first RFIC 222 and the second RFIC 224 are implemented as a single chip or a single package, the first RFIC 222 and the second RFIC 224 may be implemented as an integrated RFIC. In this case, the integrated RFIC may be connected to the first RFFE 232 and the second RFFE 234, and the integrated RFIC may convert the baseband signal into a signal of a frequency band supported by the first RFFE 232 and / or the second RFFE 234, and may transmit the converted signal to one of the first RFFE 232 and the second RFFE 234. Depending on the embodiment, the first RFFE 232 and the second RFFE 234 may be implemented as at least a portion of a single package or a single chip. Depending on the embodiment, at least one of the first antenna module 242 or the second antenna module 244 may be omitted, or may be combined with another antenna module to process RF signals of multiple frequency bands corresponding thereto.

[0066] According to an embodiment, the third RFIC 226 and the antenna 248 can be arranged on the same substrate to form a third antenna module 246. For example, the wireless communication module 192 or the processor 120 can be provided on a first substrate (e.g., a main PCB). In this case, the third antenna module 246 can be formed by providing the third RFIC 226 in a partial area (e.g., a lower surface) of a second substrate (e.g., a sub-PCB) different from the first substrate, and providing the antenna 248 in another partial area (e.g., an upper surface) of the second substrate. Providing the third RFIC 226 and the antenna 248 on the same substrate can reduce the length of the transmission line between them. This can reduce the loss (e.g., attenuation) of signals in the high-frequency band (e.g., from about 6 GHz to about 60 GHz) used for 5G network communications due to the transmission line. Therefore, the electronic device 101 can enhance the quality or speed of communication with the second network 294 (e.g., a 5G network).

[0067] According to an embodiment, the antenna 248 can be formed as an antenna array including a plurality of antenna elements that can be used for beamforming. In this case, for example, as part of the third RFFE 236, the third RFIC 226 may include a plurality of phase shifters 238 corresponding to the plurality of antenna elements. When transmitting, each of the plurality of phase shifters 238 can shift the phase of the 5G Above 6 RF signal to be transmitted from the electronic device 101 to the outside (e.g., a base station of a 5G network) through the corresponding antenna element. When receiving, each of the plurality of phase shifters 238 can shift the phase of the 5G Above 6 RF signal received from the outside through the corresponding antenna element to the same or substantially the same phase. This enables transmission or reception through beamforming between the electronic device 101 and the outside.

[0068] The second network 294 (e.g., a 5G network) can operate independently of the first network 292 (e.g., a traditional network) (e.g., standalone (SA)) or can operate while connected to the first network (e.g., non-standalone (NSA)). For example, the 5G network may include only an access network (e.g., a 5G radio access network (RAN) or a next-generation RAN (NG RAN)) and may not include a core network (e.g., a next-generation core (NGC)). In this case, the electronic device 101 can access the access network of the 5G network and then access an external network (e.g., the Internet) under the control of the core network (e.g., evolved packet core (EPC)) of the traditional network. Protocol information for communicating with the traditional network (e.g., LTE protocol information) or protocol information for communicating with the 5G network (e.g., new radio (NR) protocol information) can be stored in the memory 130 and can be accessed by another component (e.g., the processor 120, the first communication processor 212, or the second communication processor 214).

[0069] exist Figure 2A and 2B In the embodiment, the processor 120 is shown as being separate from the first communication processor 212, the second communication processor 214, or the integrated communication processor 260, but this is merely a non-limiting example. In an embodiment, the electronic device 101 may include an integrated system-on-chip (SoC) that supports the functions of the processor 120, the first network communication functions of the first communication processor 212, and the second network communication functions of the second communication processor 214. Those skilled in the art will appreciate that the operations of the processor 120, the first communication processor 212, or the second communication processor 214 may also be performed by an integrated SoC.

[0070] Although not shown, the embodiments of the present disclosure may also be applied to an electronic device 101 that supports only LTE communication. In this case, the electronic device 101 may be implemented to include the processor 120 and / or the first communication processor 212, the first RFIC 222, the first RFFE 232, and the first antenna module 242, but not include elements associated with 5G communication (e.g., at least one of the second RFIC 224, the second RFFE 234, the second antenna module 244, the second communication processor 214, the fourth RFIC 238, and the third antenna module 246).

[0071] Figure 3 is a signal flow diagram illustrating an example paging procedure in a wireless communication system according to an embodiment.

[0072] The paging procedure can be used to notify an electronic device 101 in the IDLE or INACTIVE state of an incoming call and initiate a network connection with the electronic device 101, or to notify an electronic device 101 in the CONNECTED state that system information has changed. The paging procedure can be controlled by the Mobility Management Entity (AMF) 303, and paging messages can be sent via multiple cells in a Tracking Area (TA). The paging message can be sent from the AMF 303 to the electronic device 101 via a base station (e.g., gNB 301). For efficient paging procedures, a discontinuous reception (DRX) mode can be supported. In DRX mode, the electronic device 101 can be in a sleep state most of the time without performing a receiving operation. The electronic device 101 should be able to wake up only at predetermined (e.g., specified) time intervals to observe paging information from the network. To this end, Paging Occasions (POs) and Paging Frames (PFs) are defined in NR. A paging occasion may be defined as a subframe or time point in which there is information for receiving a paging message. A paging frame may be defined as a radio frame that includes one or more paging occasions. Figure 3 In the embodiment, the electronic device 101 may observe one paging occasion (PO) per DRX cycle 313 and 317 .

[0073] According to an embodiment, the electronic device 101 may monitor the physical downlink control channel (PDCCH) in the configured paging occasions 311, 315 and 323. Monitoring of the PDCCH may mean an operation of determining whether there is downlink control information (DCI) by performing decoding using a paging radio network temporary identifier (P-RNTI) in the PDCCH, but is not limited thereto. For example, the DCI for scheduling a physical downlink shared channel (PDSCH) for a paging message may be scrambled with the P-RNTI. The electronic device 101 may detect the DCI as a result of decoding based on the P-RNTI, and may obtain time domain resource allocation information of the PDSCH based on the DCI. The electronic device 101 may identify the resources to which the paging message will be sent, and may receive the paging message from the identified resources of the PDSCH.

[0074] The intervals between the paging occasions 311, 315, and 323 may be DRX cycles 313 and 317. The electronic device 101 may not be able to detect the DCI indicating the paging message based on the result of monitoring the PDCCH at the paging occasions 311 and 315, and may enter the sleep state again. The sleep state is not restricted and is any state that consumes less power and / or fewer resources than the normal state (or active state). In one example, in the sleep state, at least one of the RFIC, RFFE, or antenna module may be turned off. In one example, in the sleep state, blocks that need to be always on in a communication processor (e.g., a modem) may be in a clock-gated state, and the remaining blocks may be in an off state. The sleep state may be referred to as an inactive state or an abnormal state.

[0075] According to an embodiment, in operation 319, the AMF 303 may transmit a paging message to the gNB 301 via S1 Application Protocol (S1AP) signaling. In operation 321, the gNB 301 may transmit DCI scrambled with the P-RNTI on the PDCCH. At paging occasion 323, the electronic device 101 may monitor the PDCCH based on the P-RNTI and detect the DCI. In operation 325, the electronic device 101 may receive the paging message via radio resource control (RRC) signaling on the PDSCH identified by the DCI. The paging message may include the identifier (UE ID) of the user equipment that the gNB 301 wants to wake up.

[0076] Figure 4A is a signal flow diagram illustrating an example method of operating an electronic device and a gNB according to an embodiment. Figure 4B Describe in more detail Figure 4A In the embodiment. Figure 4B 2 is a diagram illustrating a synchronization signal block (SSB) in a multi-beam environment according to an embodiment.

[0077] According to an embodiment, in operation 401, the gNB 301 may periodically transmit an SSB. For example, Figure 4B As shown, gNB 301 can send SSBs 411, 412, 413, 414, 415, 416, 417, 418, 419, and 420. For example, Figure 4BIn the example shown, gNB 301 is shown as transmitting two SSBs in one time slot, i.e., 14 symbols. However, those skilled in the art will appreciate that there is no limit to the number of SSBs in one time slot. gNB 301 can transmit L SSBs, and these L SSBs can be referred to as an SSB burst set. The length of an SSB burst set can be 5 ms, and the transmission period of an SSB burst set can be 20 ms, but is not limited thereto. gNB 301 can form the L SSBs of the SSB burst set into different beams, which can be represented as beam scanning performed by gNB 301. gNB 301 can form the SSBs of the SSB burst set in different directions based on digital beamforming and / or analog beamforming.

[0078] The beam scanning of the gNB 301 can increase the transmission coverage of the SSB. The first symbol 421 of the SSB 411 can include a primary synchronization signal (PSS) 431, the second symbol 422 can include a first part 432 of the physical broadcast channel (PBCH), the third symbol 423 can include a second part 433 of the PBCH, a secondary synchronization signal (SSS) 434, and a third part 435 of the PBCH, and the fourth symbol 424 can include a fourth part 436 of the PBCH.

[0079] According to an embodiment, in operation 403, the electronic device 101 (e.g., at least one of the processor 120, the first communication processor 212, the second communication processor 214, the integrated communication processor 260, or the integrated SoC) may select the best SSB. The electronic device 101 may measure the reception strength of each of the SSBs 411, 412, 413, 414, 415, 416, 417, 418, 419, and 420 formed by the gNB 301. Since the SSBs 411, 412, 413, 414, 415, 416, 417, 418, 419, and 420 are formed into different beams, the strengths measured by the electronic device 101 may be different. The electronic device 101 may select, for example, the SSB with the greatest reception strength among the SSBs. The electronic device 101 may identify, for example, the index of the SSB measured as having the greatest reception strength, and the SSB index may be used interchangeably with the beam index. In operation 405, the electronic device 101 may receive system information from the gNB 301. In operation 407, the electronic device 101 may identify a paging opportunity and a PDCCH monitoring opportunity based on the system information identified from the SSB and / or the received system information. Although not shown, the electronic device 101 may report information about the selected beam index to the gNB 301.

[0080] Hereinafter, detailed operations of the electronic device 101 identifying the paging occasion and the PDCCH monitoring occasion will be described in more detail.

[0081] According to an embodiment, the electronic device 101 may assume that the same paging message or the same short message is repeated in all transmission beams during multi-beam operation. In this case, the beam selected to receive the paging message or short message may be determined by the implementation of the electronic device. The paging message may be exactly the same with respect to paging initiated by the RAN radio access network (RAN) and paging initiated by the core network (CN). If the electronic device 101 receives a paging initiated by the RAN, the electronic device 101 may start the RRC connection recovery process. If the electronic device 101 receives a paging initiated by the CN in the RRC_INACTIVE state, the electronic device 101 may switch to the RRC_IDLE mode and may notify the network attached storage (NAS) of the switch to the RRC_IDLE mode.

[0082] The paging frame (PF) and paging occasion (PO) used for paging may be determined by the following equations. The system frame number (SFN) corresponding to the paging frame may be determined by the following equation 1. In the following equation 1, A mod B may mean a modulo operation that outputs a remainder of A divided by B.

[0083] [Equation 1]

[0084] (SFN+PF_offset)mod T=(T div N)*((UE_ID mod N)

[0085] [Equation 2]

[0086] i_s=floor(UE_ID / N)mod Ns

[0087] Parameters of [Equation 1] and [Equation 2] for determining the above-mentioned paging frame and paging occasion may be as follows.

[0088] T: DRX cycle configured in the electronic device 101 (The DRX cycle may be configured through higher layer signaling (e.g., RRC signaling, system information block (SIB), etc.)

[0089] N: total number of paging frames in T

[0090] Ns: number of paging occasions in a paging frame

[0091] PF_offset: offset value used to determine the time point of the paging frame

[0092] The UEID used to determine the paging frame and paging occasion can be determined according to the following [Equation 3].

[0093] [Equation 3]

[0094] UE_ID = 5G-S-TMSI mod 1024

[0095] 5G S-Temporary Mobile Subscription Identifier (5G-S-TMSI) may refer to a temporary terminal identifier provided by the core network to uniquely identify a terminal in a tracking area (TA). For example, the 5G-S-TMSI may be provided to the electronic device 101 through higher layer signaling. If the electronic device 101 has not yet registered in the network, the electronic device 101 may assume that the UE_ID is 0. The terminal ID used for paging may correspond to a parameter determined by an International Mobile Subscriber Identity (IMSI). In the present disclosure, the terminal ID used for paging is generalized and used as UE_ID. The UE_ID may include a value that can be configured based on the 5G-S-TMSI and a value that can be derived from the IMSI value.

[0096] The PDCCH monitoring occasion for paging may be determined by information about the configuration of the paging search space (e.g., the search space indicated by the higher layer signaling parameter pagingSearchSpace) and the configuration of the first PDCCH monitoring occasion of the paging occasion (e.g., the higher layer signaling parameter firstPDCCH-MonitoringOccasionOfPO), and by the number of PDCCH monitoring occasions per SSB in the paging occasion (e.g., the higher layer signaling parameter nrofPDCCH-MontiroingOccasionPerSSB-InPO). pagingSearchSpace, firstPDCCH-MonitoringOccasionOfPO, and nrofPDCCH-MontiroingOccasionPerSSB-InPO may be specifically defined as shown in Table 1 below.

[0097] [Table 1]

[0098]

[0099] When the paging search space is configured as a search space with a search space ID of 0, if the number of paging opportunities (Ns) of a paging frame is 1, one paging opportunity may exist in the paging frame, and if Ns is 2, two paging opportunities may exist in the paging frame, the first paging opportunity (i_s=0) may exist in the first half frame of the paging frame, and the second paging opportunity (i_s=1) may exist in the second half frame of the paging frame. The search space with a search space ID of 0 may correspond to the search space configured from the master information block (MIB).

[0100] If the paging search space is configured as a search space with a search space ID other than 0, the electronic device 101 may monitor the (i_s+1)th paging occasion. One paging occasion may be configured as a set of "S*X" consecutive PDCCH monitoring occasions, where "S" may correspond to the number of SSBs actually transmitted, and the corresponding information may be transmitted from the base station (e.g., gNB 301) to the electronic device 101 as a specific parameter (e.g., ssb-PositionsInBurst) value of the system information block (SIB). In addition, "X" may correspond to the number of PDCCH monitoring occasions per SSB in the paging occasion configured in the electronic device 101 from the base station (e.g., gNB 301) (e.g., higher layer signaling parameter nrofPDCCH-MonitoringOccasionPerSSB-InPO), and if there is no corresponding configuration information, the electronic device 101 may assume that X=1. The [x*S+K]th (here, x=0, 1, 2, ..., X-1, and K=1, 2, 3, ...S) PDCCH monitoring occasion in the paging occasion may correspond to the kth transmission SSB. Starting from the first PDCCH monitoring occasion in the paging frame, the PDCCH monitoring occasions that do not overlap with uplink (UL) symbols may be numbered sequentially starting from 0. At this time, if firstPDCCH-MonitoringOccasionOfPO has been configured through higher layer signaling, the starting PDCCH monitoring occasion number of the (i_s+1)th paging occasion may correspond to the (i_s+1)th value in the firstPDCCH-MonitoringOccasionOfPO parameter. If firstPDCCH-MonitoringOccasionOfPO is not configured through higher layer signaling, the starting PDCCH monitoring occasion number of the (i_s+1)th paging occasion may be the same as i_s*S*X. If X>1, when the electronic device 101 detects the PDCCH corresponding to the P-RNTI at the paging occasion, the electronic device 101 does not need to perform monitoring on the remaining or subsequent PDCCH monitoring occasions at the corresponding paging occasions. A paging occasion associated with a certain paging frame may start within the corresponding paging frame or after the corresponding paging frame. The PDCCH monitoring occasion of a predetermined paging occasion may exist over multiple radio frames. When the search space for paging is configured as a search space whose search space ID has a value other than 0, the PDCCH monitoring opportunity of one paging occasion may exist over multiple time periods of the paging search space.

[0101] Figure 5A is a flowchart illustrating an example method of operating an electronic device according to an embodiment. Figure 5B describe Figure 5A In the embodiment. Figure 5B is a diagram showing a correspondence relationship between time slots and SSBs according to an embodiment.

[0102] According to an embodiment, in operation 501, the electronic device 101 (e.g., at least one of the processor 120, the first communication processor 212, the second communication processor 214, the integrated communication processor 260, or the integrated SoC) may enter a DRX mode. In the DRX mode, as described above, the electronic device 101 may wake up for a predetermined duration to monitor the PDCCH, and when it is determined based on the monitoring result of the PDCCH that no paging message has been received, it may enter a sleep state again. The electronic device 101 may be in a sleep state in the DRX mode, and in operation 503, may wake up at a paging occasion (PO) to monitor the PDCCH.

[0103] In an embodiment, the electronic device 101 may receive a configured DRX cycle for paging from a base station (e.g., gNB 301). As described above, the electronic device 101 may identify a paging frame, a paging occasion, and at least one PDCCH monitoring occasion among the paging occasions based on Equations 1 and 2. For example, there may be S*X PDCCH monitoring occasions, and the PDCCH monitoring occasions may correspond to S SSBs, respectively. Here, the PDCCH monitoring occasion may be referred to as a time slot. For example, Figure 5B As shown, one paging opportunity (PO) may include S*X PDCCH monitoring opportunities 531, 532, 533, 534, 535, 536, 537, 538, 539, 540 (which may be referred to as monitoring opportunities 531 to 540). S may be the number of SSBs. The SSBs may correspond to corresponding beam indices 551, 552, 553, 554, 555, 556, 557, 558 (which may be referred to as beam indices 551 to 558). Figure 5B S is shown as 8, but this is merely a non-limiting example. For example, since the first PDCCH monitoring opportunity 531 corresponds to the first beam index 551 corresponding to the first SSB, PDCCH monitoring opportunities 531, 532, 533, 534, 535, 536, 537, and 538 (which may be referred to as monitoring opportunities 531 to 538) may correspond to the first beam index 551 to the eighth beam index 558, respectively. Since an SSB corresponds to a beam index, those skilled in the art will understand that the PDCCH monitoring opportunity may be expressed as corresponding to the SSB.

[0104] For example, in the first PDCCH monitoring opportunity 531 corresponding to the first beam index 551, the base station (e.g., gNB 301) may transmit DCI to the first beam index 551 and / or may transmit a paging message to the first beam index 551 in the PDSCH configured as the first PDCCH monitoring opportunity 531. The base station (e.g., gNB 301) may repeatedly transmit the same paging message in multiple beam indices 551 to 558. Thus, the electronic device 101 may identify at least one of the paging messages transmitted based on each of the multiple beam indices 551 to 558. The electronic device 101 may select any one of the paging messages based on the multiple beam indices 551 to 558, may select all of the paging messages, or may select some of the paging messages, as will be described later. When the electronic device 101 selects at least one paging message instead of all paging messages, the electronic device 101 may wake up only on the PDCCH monitoring opportunity corresponding to the corresponding beam index, thereby reducing the wake-up duration.

[0105] Figure 6A is a flowchart illustrating an example method of operating an electronic device according to an embodiment. Figure 6B describe Figure 6A Example of . Figure 6B is a diagram showing a correspondence relationship between time slots and SSBs according to an embodiment.

[0106] According to an embodiment, in operation 601, the electronic device 101 (e.g., at least one of the processor 120, the first communication processor 212, the second communication processor 214, the integrated communication processor 260, or the integrated SoC) may receive a plurality of SSBs. As described above, the gNB 301 may sequentially transmit a plurality of SSBs based on each of a plurality of beam indices, and the electronic device 101 may sequentially receive each of the SSBs transmitted by the gNB 301. In operation 603, the electronic device 101 may identify a plurality of time slots corresponding to the plurality of SSBs, respectively. For example, the electronic device 101 may identify a paging opportunity (PO) and a plurality of PDCCH monitoring opportunities 531, 532, 533, 534, 535, 536, 537, and 538 in the paging opportunity (PO) based on information contained in the received SSB and / or the received system information, such as Figure 5B and 6B The plurality of PDCCH monitoring opportunities 531, 532, 533, 534, 535, 536, 537, and 538 may correspond to a plurality of SSBs, respectively.

[0107] According to an embodiment, in operation 605, in the DRX mode, the electronic device 101 may select at least one time slot to be monitored in the current period based on a measurement result of a signal measured during at least one time slot among a plurality of time slots in the previous period. In one example, the electronic device 101 may identify the result of the measurement performed during the time slot corresponding to the beam index of the best beam in the previous period.

[0108] For example, reference Figure 6B , the electronic device 101 may identify the strength of the signal corresponding to the best beam index 553 in the previous period 630. For example, the electronic device 101 may identify the strength of the SSB during the time slot corresponding to the best beam index 553 (or during the time interval corresponding to the time slot). Those skilled in the art will understand that the SSB is merely a non-limiting example and is not limited as long as the SSB is a signal from the base station that can be measured during the time slot corresponding to the best beam index 553 (or the time interval corresponding to the time slot). Those skilled in the art will understand that the electronic device 101 may measure the strength of the signal without limitation as long as the signal is a signal having a QCL relationship with the SSB. The electronic device 101 may measure at least one of the reference signal received power (RSRP), the reference signal received quality (RSRQ), the signal to interference plus noise ratio (SINR), or the received signal strength indicator (RSSI) of the signal as the strength of the signal, but any parameter that can represent the strength of the signal is possible without limitation.

[0109] exist Figure 6B In the present embodiment, when the strength of the signal corresponding to the beam index 553 in the previous period 630 satisfies a specified condition, the electronic device 101 may select the time slot 533 corresponding to the corresponding beam index 553 as the time slot to be monitored in the current period 640. For example, when the strength of the signal corresponding to the beam index 553 in the previous period 630 exceeds a threshold value, the electronic device 101 may select the time slot 533 corresponding to the corresponding beam index 553 as the time slot to be monitored in the current period 640. When the strength of the signal corresponding to the beam index 553 in the previous period 630 is less than or equal to the threshold value, the electronic device 101 may select all time slots 531 to 538 corresponding to one SSB burst set as the time slots to be monitored in the current period 640.

[0110] According to an embodiment, in operation 607, the electronic device 101 may wake up in at least one selected time slot to monitor the PDCCH. Figure 6BWhen the time slot 533 is selected as the time slot to be monitored in the current period 640, the electronic device 101 may wake up in the time slot 533 to perform monitoring. When all the time slots 531 to 538 corresponding to one SSB burst set are selected as the time slots to be monitored in the period 640, the electronic device 101 may wake up during the time slots 531 to 538 to perform monitoring.

[0111] exist Figure 6A In the embodiment, it has been described that the electronic device 101 selects the time slot to be monitored in the current period based on the signal measurement result in a specific time slot in the previous period (for example, the time slot corresponding to the best beam index). However, it will be understood by those skilled in the art that the electronic device 101 can select any time interval in which the signal corresponding to the best beam index can be measured, and the time slot corresponding to the best beam index, without limitation. For example, when a signal has a QCL relationship with the signal of the best beam index, even if the signal is a signal other than SSB, the electronic device 101 can use the measurement result of the signal without limitation. For example, when the reference signal corresponding to the best beam index is measured in the previous period (or in the past), the electronic device 101 can select the time slot to be monitored in the current period based on the measurement result. In an embodiment, it will be understood by those skilled in the art that the determination by the electronic device 101 whether the strength of the signal measured in the time slot of the previous period meets the specified condition can be replaced by determining whether the strength of the predetermined signal associated with the specific beam index meets the specified condition at a predetermined past time point.

[0112] Figure 6C is a flowchart illustrating an example method of operating an electronic device according to an embodiment.

[0113] According to an embodiment, in operation 641, the electronic device 101 (e.g., at least one of the processor 120, the first communication processor 212, the second communication processor 214, the integrated communication processor 260, or the integrated SoC) may wake up in at least one selected time slot to decode the PDCCH. In operation 643, the electronic device 101 may determine whether a paging message from the gNB 301 exists based on the decoding result. In the at least one selected time slot, the electronic device 101 may determine whether a DCI for paging exists based on the P-RNTI. Upon identifying the DCI scheduling a paging message in the PDSCH, the electronic device 101 may determine that a paging message exists.

[0114] According to an embodiment, when it is determined that there is no paging message from the gNB 301 (643-No), the electronic device 101 may switch to the sleep state again in operation 645. In operation 647, the electronic device 101 may reselect the time slot to be monitored. The electronic device 101 may reselect the time slot to be monitored, for example, based on the result of measurement when awakened by operation 641 (or when awakened by another operation). Therefore, each time a DRX cycle passes, a time slot to be monitored (e.g., a PDCCH monitoring opportunity) may be selected, and a wake-up duration may be selected for each DRX cycle. When it is determined that there is a paging message (643-Yes), in operation 649, the electronic device 101 may receive the paging message in the PDSCH corresponding to at least one selected time slot.

[0115] Figure 7A is a flowchart illustrating an example method of operating an electronic device according to an embodiment. Figure 7B and Figure 7C describe Figure 7A In the embodiment. Figure 7B and Figure 7C is a diagram showing a correspondence relationship between time slots and SSBs according to an embodiment.

[0116] According to an embodiment, in operation 701, the electronic device 101 (e.g., at least one of the processor 120, the first communication processor 212, the second communication processor 214, the integrated communication processor 260, or the integrated SoC) may identify a plurality of time slots. Since the operation of the electronic device 101 to identify the time slot corresponding to each SSB based on the system information has been described in detail, its description will not be repeated here. In operation 703, the electronic device 101 may determine whether the strength of the first signal measured in the first time slot in the previous period meets a specified condition. For example, the specified condition may be whether the strength of the first signal exceeds a specified threshold, but any condition that can indicate that the channel state in the corresponding beam index is good may be a specified condition without limitation.

[0117] According to an embodiment, when it is determined that the strength of the first signal measured in the first time slot in the previous period meets the specified condition (703-Yes), the electronic device 101 may wake up and perform monitoring in the time slot of the first group in operation 705. When it is determined that the strength of the first signal measured in the first time slot in the previous period does not meet the specified condition (703-No), in operation 707, the electronic device 101 may wake up and perform monitoring in the time slot of the second group.

[0118] For example, reference Figure 7B, the electronic device 101 may measure the strength of a signal (e.g., SSB) corresponding to a beam index 713 among a plurality of beam indices 711, 712, 713, 714, 715, 716, 717, 718 (which may be referred to as indices 711 to 718) at a first time point T1. The electronic device 101 may select a time slot to be monitored at a current time point T2 based on whether the signal strength at the first time point T1 satisfies a specified condition. When the signal strength at the first time point T1 exceeds a threshold value Th, the electronic device 101 may select a time slot corresponding to the beam index 713 of the best beam as the time slot to be monitored. Therefore, the electronic device 101 may wake up only in the time slot corresponding to the beam index 713, and may be in a sleep state in the remaining time slots, thereby preventing / reducing power consumption and / or resource consumption. When the signal strength at the first time point T1 is less than or equal to the threshold Th, the electronic device 101 can select the time slots corresponding to all beam indices 711 to 718 corresponding to one SSB burst set as the time slots to be monitored. Therefore, when the channel environment deteriorates, the possibility of missing a paging message can be reduced by monitoring multiple time slots.

[0119] In another example, reference Figure 7C , when the signal strength at the first time point (T1) exceeds the threshold value Th, the electronic device 101 may select the time slot corresponding to the beam index 713 of the best beam as the time slot to be monitored. When the signal strength at the first time point T1 is less than or equal to the threshold value Th, the electronic device 101 may select the time slots corresponding to the plurality of beam indices 712, 713, and 714 among all beam indices 711 to 718 corresponding to one SSB burst set as the time slots to be monitored. For example, the plurality of beam indices 712, 713, and 714 may be candidate beam indices, but there is no limitation.

[0120] Figure 8 is a flowchart illustrating an example method of operating an electronic device according to an embodiment.

[0121] According to an embodiment, in operation 801, the electronic device 101 (e.g., at least one of the processor 120, the first communication processor 212, the second communication processor 214, the integrated communication processor 260, or the integrated SoC) may receive multiple SSBs. In operation 803, the electronic device 101 may identify multiple time slots corresponding to the multiple SSBs. As described above, the electronic device 101 may identify multiple time slots corresponding to the multiple SSBs based on the received system information.

[0122] According to an embodiment, in operation 805, in the DRX mode, the electronic device 101 may select the number of at least one time slot to be monitored in the current period based on the measurement result of the signal measured during at least one time slot among the plurality of time slots in the previous period. For example, the electronic device 101 may store the measurement result and related information, such as the number of time slots shown in Table 2.

[0123] [Table 2]

[0124] Signal strength Number of time slots First range 1 Second range 3 The third scope 5

[0125] For example, when it is determined that the strength of the signal measured in the previous time period falls within the first range, the electronic device 101 may determine that the number of time slots is one based on the relevant information shown in Table 1. In this case, the electronic device 101 may select the time slot corresponding to the beam index of the best beam as the time slot to be monitored. When it is determined that the number of time slots is three, the electronic device 101 may select three time slots corresponding to the beam index of the best beam and two beam indices adjacent to the beam index of the best beam. When it is determined that the number of time slots is five, the electronic device 101 may select five time slots corresponding to the beam index of the best beam and five consecutive beam indices including the beam index of the best beam. In operation 807, the electronic device 101 may wake up in at least one time slot whose number has been selected and perform monitoring.

[0126] Figure 9 is a flowchart illustrating an example method of operating an electronic device according to an embodiment.

[0127] exist Figure 9 In an embodiment, it is assumed that the electronic device 101 chooses to wake up in multiple time slots in the current time period based on the signal measurement results in the previous time period. According to an embodiment, in operation 901, in multiple selected time slots, the electronic device 101 (for example, at least one of the processor 120, the first communication processor 212, the second communication processor 214, the integrated communication processor 260, or the integrated SoC) may wake up and receive signals. In operation 903, the electronic device 101 may merge the signals received in the multiple time slots. For example, the electronic device 101 may merge the signals received in the multiple time slots based on chase combining. For example, chase combining may be a combining method used in a CC HARQ process and may be applied to the present disclosure. The electronic device 101 may store the bits received in the multiple time slots in a buffer and may combine (for example, sum) the bits.

[0128] According to an embodiment, in operation 905, the electronic device 101 may decode the result of the merging. For example, when using tracking merging, the electronic device 101 may use the P-RNTI to decode the result of summing the results stored in the buffer. In operation 907, the electronic device 101 may identify the DCI based on the decoding result. When it is determined based on the DCI that resources for the paging message are allocated to the PDSCH, the electronic device 101 may receive the paging message in each of a plurality of PDSCHs corresponding to a plurality of time slots, respectively. The electronic device 101 may receive the paging message in each of a plurality of PDSCHs. The electronic device 101 may merge the paging messages in each of the plurality of PDSCHs, and may determine whether the paging message is for the electronic device 101 based on the merging result.

[0129] Figure 10 is a flowchart illustrating an example method of operating an electronic device according to an embodiment.

[0130] According to an embodiment, in operation 1001, the electronic device 101 (e.g., at least one of the processor 120, the first communication processor 212, the second communication processor 214, the integrated communication processor 260, or the integrated SoC) may identify a plurality of time slots. As described above, the electronic device 101 may identify a plurality of time slots each corresponding to an SSB of an SSB burst set.

[0131] According to an embodiment, in operation 1003, the electronic device 101 may determine whether at least one condition related to the movement of the electronic device 101 is satisfied. For example, a communication processor of the electronic device 101 (e.g., at least one of the first communication processor 212, the second communication processor 214, or the integrated communication processor 260) may determine information about the movement of the electronic device 101 based on information sensed by the communication processor. The communication processor may determine the information about the movement of the electronic device 101 based on the stability of the measured signal strength. Whether the electronic device 101 has moved may be determined based on the stability of the signal strength.

[0132] Alternatively, as Figure 11As shown, a communication processor 1100 (e.g., at least one of the first communication processor 212, the second communication processor 214, or the integrated communication processor 260) may receive information 1102 about the movement of the electronic device 101 from a processor 120 (e.g., an application processor). The processor 120 may receive sensing data 1101 for motion measurement from at least one sensor (e.g., at least one of a linear accelerometer, a gyroscope sensor, or a geomagnetic sensor) of a sensor module (e.g., including at least one sensor) 176. The processor 120 may determine information about the movement of the electronic device 101 based on the sensing data 1101. The processor 120 may send the information 1102 about the movement to a communication processor (e.g., including a communication circuit) 1100. The information 1102 about the movement may be information about the actual movement of the electronic device 101, but in another example, may be implemented in the form of a flag indicating whether there is movement.

[0133] According to an embodiment, the electronic device (e.g., a communication processor) may determine whether at least one condition related to movement is satisfied based on information about movement. At least one condition related to movement may be determined so that it can be determined that the electronic device 101 can be determined to be in a non-moving state taking into account tolerance. When it is determined that at least one condition is satisfied (1003-Yes), in operation 1005, the electronic device 101 may wake up in the time slots of the first group and perform monitoring. When it is determined that at least one condition is not satisfied (1003-No), in operation 1007, the electronic device 101 may wake up in the time slots of the second group and perform monitoring. As described above, for example, the time slots of the first group may be time slots of the beam index corresponding to the best beam, but there is no limitation. The second group of time slots may be time slots of all beam indices corresponding to the SSBs of one SSB burst set, or may be time slots of beam indices corresponding to multiple candidate beams.

[0134] Although not shown, in an embodiment, the electronic device 101 may determine the degree of mobility of the electronic device 101. Similar to Table 1, the electronic device 101 may store, for example, information related to the degree of mobility and the number of time slots. The electronic device 101 may, for example, identify the number of time slots corresponding to the measured degree of mobility based on the information. The electronic device 101 may wake up and perform monitoring in the time slot corresponding to the number of identified beam indices, including the beam index of the optimal beam.

[0135] In an embodiment, the electronic device 101 may use both the condition of whether the measured signal strength exceeds a threshold and the condition of movement to select a time slot in which monitoring is to be performed.

[0136] Figure 12 is a flowchart illustrating an example method of operating an electronic device according to an embodiment.

[0137] According to an embodiment, in operation 1201, the electronic device 101 (e.g., at least one of the processor 120, the first communication processor 212, the second communication processor 214, the integrated communication processor 260, or the integrated SoC) may identify a plurality of time slots. As described above, the electronic device 101 may identify a plurality of time slots each corresponding to an SSB of an SSB burst set.

[0138] According to an embodiment, in operation 1203, the electronic device 101 may determine whether the intensity change in a specific time slot during the specified duration of the electronic device 101 is less than a threshold change. When the electronic device 101 is not moving, it may be efficient for the electronic device 101 to perform monitoring in some time slots (e.g., the time slot corresponding to the best SSB) rather than monitoring the time slots of all SSBs corresponding to the SSB burst set. On the other hand, when the electronic device 101 moves, the electronic device 101 may monitor the time slots corresponding to all SSBs of the SSB burst set rather than only monitoring the time slot corresponding to the existing best SSB, thereby achieving accurate decoding. This is because the reception conditions of the existing best SSB may deteriorate when the electronic device 101 moves. Therefore, when it is determined that the electronic device 101 has moved, the electronic device 101 may monitor all time slots and may newly identify the best beam index again later. When it is determined that the electronic device 101 enters a stable state again later, the electronic device 101 may monitor the newly identified time slot.

[0139] exist Figure 11In the embodiment of the invention, it has been described that the communication processor 1100 of the electronic device 101 receives the information 1102 about movement from the processor 120 (e.g., an application processor), but the communication processor 1100 can determine whether the electronic device 101 has moved without information from the outside. When the electronic device 101 does not move, there is a high possibility that the reception intensity of the signal of the specific beam index does not change. When the electronic device 101 moves, there is a high possibility that the reception intensity of the signal of the specific beam index changes. It can be determined based on whether the reception intensity of the signal of the specific beam index is stable. Therefore, in operation 1203, the electronic device 101 can determine whether the intensity change in a specific time slot during a specified duration is less than a threshold change, and can determine whether the electronic device 101 has moved based on the result of the determination. When the electronic device 101 has not moved in consideration of the tolerance, it will be determined that the intensity change in the specific time slot during the specified duration (which is the condition in operation 1203) is less than the threshold change. When it is determined that the intensity change in a specific time slot during the specified duration is less than the threshold change (1203-Yes), in operation 1205, the electronic device 101 may wake up in the time slots of the first group to perform monitoring. For example, the first group may be time slots corresponding to some SSBs (e.g., the best SSB) of an SSB burst set. When the electronic device 101 moves in consideration of tolerance, it will be determined that the intensity change in a specific time slot during the specified duration (which is the condition in operation 1203) is greater than or equal to the threshold change. When it is determined that the intensity change in a specific time slot during the specified duration is greater than or equal to the threshold change (1203-No), in operation 1207, the electronic device 101 may wake up in the time slots of the second group and perform monitoring. As described above, the second group of time slots may be time slots whose number enables stable decoding of the signal, and in one example, may be time slots corresponding to all SSBs in one SSB burst set or time slots corresponding to candidate beam indices.

[0140] The electronic device 101 according to the embodiment may use whether the strength of the received signal satisfies a specified condition (such as Figure 7A ) and whether at least one condition related to the movement of the electronic device 101 is satisfied (as shown in Figure 10 as shown) to select the time slot to be monitored.

[0141] Figure 13 is a flowchart illustrating an example method of operating an electronic device according to an embodiment.

[0142] According to an embodiment, in operation 1301, the electronic device 101 (e.g., at least one of the processor 120, the first communication processor 212, the second communication processor 214, the integrated communication processor 260, or the integrated SoC) may identify a plurality of time slots. In operation 1303, the electronic device 101 may determine whether the strength of the first signal measured in the first time slot in the previous period satisfies a specified condition. For example, the electronic device 101 may determine whether the strength of the first signal exceeds a specified threshold as whether the specified condition is satisfied, but the condition is not limited thereto.

[0143] According to an embodiment, when it is determined that the strength of the first signal meets a specified condition (1303-Yes), in operation 1305, the electronic device 101 may wake up in a first group of time slots and perform monitoring based on the first group of antennas. For example, the first group of antennas may be a group including at least one of the antennas included in the second antenna module 244 and the third antenna module 246. When it is determined that the strength of the first signal does not meet the specified condition (1303-No), in operation 1307, the electronic device 101 may wake up in a second group of time slots different from the first group and perform monitoring based on a second group of antennas. For example, the second group of antennas may be a group including at least one of the antennas included in the second antenna module 244 and the third antenna module 246, and may include more antennas than the first group. Compared to using the first group of antennas, using the second group of antennas can increase antenna diversity and increase the probability of successful decoding. Therefore, when it is determined that the channel environment has deteriorated, the electronic device 101 can use more antennas to perform monitoring and perform monitoring in more time slots, thereby increasing the probability of successful decoding.

[0144] In this example, when the electronic device 101 is monitoring based on the first group of antennas, the electronic device 101 may detect that the strength of the first signal does not meet a specified condition. In this case, the electronic device 101 may determine whether there are idle antennas. If it is determined that there are idle antennas, the electronic device 101 may be configured to perform monitoring by additionally using at least some of the idle antennas.

[0145] Although not shown, in operation 1303, the electronic device 101 according to an embodiment may select an antenna group based on whether the electronic device 101 has moved rather than whether the signal strength satisfies a specified condition. When it is determined that the electronic device 101 has not moved significantly, as in operation 1305, the electronic device 101 may wake up in the time slot of the first group and perform monitoring based on the first group of antennas. When it is determined that the electronic device 101 has moved significantly, as in operation 1307, the electronic device 101 may wake up in the time slot of the second group and perform monitoring based on the second group of antennas.

[0146] According to an example embodiment, an electronic device may include: a memory; a communication module; and at least one processor, wherein the at least one processor is configured to receive a plurality of synchronization signal / PBCH blocks (SSBs) from a network via the communication module, identify a plurality of time slots corresponding to the plurality of SSBs, respectively, select at least one time slot to be monitored in a current period based on a measurement result of a signal measured in at least one of the plurality of time slots in a previous period in a discontinuous reception (DRX) mode, and wake up and monitor a physical downlink control channel (PDCCH) in the selected at least one time slot.

[0147] According to an example embodiment, the at least one processor may be configured to select at least a portion of at least one time slot in which monitoring is to be performed in a current time period from a plurality of time slots in a previous time period as a function of whether the strength of a signal corresponding to an optimal beam index satisfies a specified condition.

[0148] According to an example embodiment, the at least one processor may be configured to, as at least part of selecting at least one time slot in which to perform monitoring in a current period: select a first group of time slots based on a strength of a signal corresponding to the best beam index being determined to exceed a threshold, and select a second group of time slots different from the first group based on a strength of a signal corresponding to the best beam index being determined to be equal to or less than a threshold.

[0150] According to an example embodiment, the at least one processor may further be configured to detect downlink control information (DCI) indicating whether a paging message exists in a time slot corresponding to an optimal beam index, and based on detecting the DCI, receive the paging message in a physical downlink shared channel (PDSCH) reserved based on the DCI via the communication module.

[0152] According to an example embodiment, the at least one processor may also be configured to detect multiple pieces of downlink control information (DCI) indicating whether a paging message is present in each of a plurality of time slots, and based on detecting the multiple pieces of DCI, receive, via the communication module, a paging message in each physical downlink shared channel (PDSCH) reserved based on the DCI.

[0153] According to an example embodiment, as at least a part of detecting multiple DCIs indicating whether a paging message is present in each of a plurality of time slots, at least one processor may be configured to: merge signals received in each of the plurality of time slots, and detect the multiple DCIs based on a result of decoding the merged result according to a paging radio network temporary identifier (P-RNTI) assigned to the electronic device.

[0154] According to an example embodiment, as at least part of waking up and monitoring the PDCCH in at least one selected time slot, the at least one processor may be configured to: wake up in a time slot of a first group and perform monitoring based on a first group of antennas of the electronic device based on the strength of the signal corresponding to the best beam index being determined to be greater than a threshold, and wake up in a time slot of a second group and perform monitoring based on a second group of antennas different from the first group based on the strength of the signal corresponding to the best beam index being determined to be equal to or less than a threshold.

[0155] According to an example embodiment, as at least a part of selecting at least one time slot to be monitored in a current time period based on a measurement result of a signal measured in at least one time slot among a plurality of time slots in a previous time period, the at least one processor may be configured to: measure the reception strength of the SSB corresponding to the optimal beam index, and based on the reception strength, select at least one time slot to be monitored in the current time period.

[0156] According to an example embodiment, the at least one processor may be further configured to wake up in the selected at least one PDCCH monitoring opportunity, monitor the PDCCH, and enter a sleep state when there is no paging message as a result of the monitoring.

[0157] According to an example embodiment, the at least one processor may be further configured to, after entering the sleep state, reselect a time slot in which monitoring is to be performed in a next period based on a measurement result of another signal measured during wake-up.

[0158] According to an example embodiment, an electronic device may include: a memory; a communication module; and at least one processor, wherein the at least one processor is configured to receive a plurality of synchronization signal (SS) / physical broadcast channel (PBCH) blocks (SSBs) from a network via the communication module, identify a plurality of time slots corresponding to the plurality of SSBs, respectively, select at least one time slot to be monitored in a current period based on information associated with movement of the electronic device in a discontinuous reception (DRX) mode, wake up in at least one selected physical downlink control channel (PDCCH) monitoring opportunity, and monitor the PDCCH.

[0159] According to an example embodiment, the at least one processor may be configured to, as at least part of selecting at least one time slot in which to perform monitoring in the current time period, select at least one time slot in which to perform monitoring in the current time period from a plurality of time slots in a previous time period based on whether a change in the strength of a signal corresponding to an optimal beam index during a specified time duration is less than a threshold change.

[0160] According to an example embodiment, as at least part of selecting at least one time slot in which to perform monitoring in a current time period, the at least one processor may be configured to: select a first group of time slots based on a change in the strength of a signal corresponding to the best beam index being determined to be less than a threshold change, and select a second group of time slots different from the first group based on a change in the strength of a signal corresponding to the best beam index being determined to be equal to or greater than the threshold change.

[0161] According to an example embodiment, the electronic device may further include at least one sensor configured to sense data associated with the movement of the electronic device, wherein the at least one processor is configured to select at least one time slot in which to perform monitoring in a current time period based on information associated with the movement of the electronic device identified based on the sensing data identified by the at least one sensor.

[0162] According to an example embodiment, a method of operating an electronic device may include: receiving a plurality of synchronization signal / PBCH blocks (SSBs) from a network; identifying a plurality of time slots corresponding to the plurality of SSBs, respectively; selecting at least one time slot to be monitored in a current period based on a measurement result of a signal measured in at least one of the plurality of time slots in a previous period in a discontinuous reception (DRX) mode; and waking up and monitoring a physical downlink control channel (PDCCH) in the selected at least one time slot.

[0163] According to an example embodiment, when selecting at least one time slot for performing monitoring in a current time period, at least one time slot for performing monitoring in the current time period may be selected from a plurality of time slots in a previous time period based on whether the strength of a signal corresponding to an optimal beam index satisfies a specified condition.

[0164] According to an example embodiment, selecting at least one time slot in which monitoring is to be performed in the current period may include: selecting a first group of time slots based on the strength of the signal corresponding to the best beam index being determined to exceed a threshold, and selecting a second group of time slots different from the first group based on the strength of the signal corresponding to the best beam index being determined to be equal to or less than a threshold.

[0165] According to an embodiment, when the time slots of the first group are selected based on the strength of the signal corresponding to the best beam index being determined to exceed a threshold, the time slot corresponding to the best beam index may be selected as the time slot of the first group.
