[0020] Some aspects of this disclosure relate to systems, apparatus, and methods for implementing paging warning designs for a UE operating in an NTN for wireless communication. For example, systems, apparatus, and methods are provided for notifying a user of the UE that the UE has physically moved to prepare to receive a paging message.

[0021] In some respects, the UE is battery-powered and therefore has limited energy when not recharged. One way to reduce energy consumption is to enter a power-saving mode or sleep mode when no data transmission or very little data transmission is expected. For example, when no phone calls are expected for a period of time, the UE can enter sleep mode for that period. In some respects, data transmission includes phone calls. The UE consumes much less energy in sleep mode. When a call is scheduled, the base station serving or monitoring the UE can send a paging message to the UE, and the UE can wake up and prepare to receive a phone call upon receiving the paging message. In some respects, the UE is configured with one or more paging times and receives a paging message during at least one of the one or more paging times. One or more paging times are time periods during which a paging message can be received. Therefore, the UE can wake up during each of the one or more paging times to attempt to receive a paging message. If a paging message is received during a paging time, the UE can wake up based on the paging message. For example, the UE can remain awake to receive additional communications, such as phone calls and / or data transmissions. For example, the UE can return to sleep mode and wake up again later to receive additional communication. If no paging message is received during a paging session, the UE can return to sleep mode and wake up again during the next paging session. In this case, the UE conserves energy by remaining in sleep mode outside of one or more paging sessions.

[0022] In some respects, the UE may need to maintain synchronization with the base station in order to receive paging messages. For example, the UE needs to maintain synchronization with the base station to know when one or more paging times arrive and to receive paging messages at at least one of the paging times. In some respects, the UE can maintain synchronization by receiving a Synchronization Signal Block (SSB) signal from the base station. For example, the UE may need to periodically wake up to receive the SSB signal to synchronize with the base station. Alternatively, the UE may not need to be fully awake to receive the SSB signal. Specifically, the UE may be equipped with a primary transceiver and a secondary transceiver. The secondary transceiver may consume less power than the primary transceiver. In this case, the UE can use the secondary transceiver to receive the SSB signal and thus save power.

[0023] In some aspects, the base station can send an Early Paging Indication (PEI) to the UE to indicate whether a paging message should be sent during the next paging time. For example, the base station can send the PEI after the SSB signal. When the PEI indicates that a paging message should be sent during the next paging time, the UE can continue to receive the SSB signal and synchronize with the base station. Otherwise, when the PEI indicates that a paging message should not be sent during the next paging time, the UE can ignore the SSB signal until the next paging time. In this case, when a paging message is not expected, the UE saves energy by not receiving the SSB signal.

[0024] In some respects, the UE may be served by an NTN wireless communication network. For example, the UE may connect to a base station via satellite. In some respects, the satellite allocates a tight link budget to the UE. For example, when the UE is placed in a pocket or backpack, or when the UE is in a location where its line of sight (LoS) to the satellite is blocked, the UE may not be able to receive signals from the satellite. Therefore, the UE may occasionally fail to receive paging messages or subsequent telephone calls. In some respects, the base station may send a paging alert (PA) to the UE via satellite to trigger a notification to the UE's user. Compared to other signals sent to the UE (e.g., PEI), the base station can send the PA with a higher link budget. For example, the PA can be sent at a higher power, resulting in higher received signal power or a higher signal-to-noise ratio (SNR). Alternatively, the PA can be sent with a lower-order modulation and / or a lower decoding rate, making the signal carrying the PA more robust. In either case, the UE can receive the PA even when it is placed in a pocket or in a location without a LoS to the satellite. The base station may send the PA in place of the PEI or in addition to the PEI. In some respects, the PA (Power Aspect) may instruct the UE to prepare to receive an upcoming paging message. In other respects, the notification may instruct the user to physically move the UE to obtain better signal reception. For example, the UE may determine that the signal strength of the received signal from the base station is too low to detect and receive a paging message, and thus generate a notification for the user. The notification may prompt the user to remove the UE from their pocket or backpack. The notification may also prompt the user to physically move the UE to higher ground, making the Loss of Signal (LoS) available. In some respects, the notification may indicate that the signal strength is too low and action is required. In other respects, the notification may indicate that the UE needs to physically move to a different location to obtain better signal reception. In either case, the notification may at least prompt the user to remove the UE from their pocket or backpack to check the notification. The notification may be an audio message, a series of vibrations, and / or a text message. After the user physically moves the UE, the UE may receive a subsequent paging message and wake up to receive further communications.

[0025] Figure 1 An example system 100 for implementing paging alerts in an NTN wireless network is illustrated according to some aspects of this disclosure. The example system 100 is provided for illustrative purposes only and is not intended to limit the aspects disclosed. The example system 100 may include, but is not limited to, a UE 102 and a base station 104. At least a portion of the base station 104 is implemented as a satellite, such as... Figure 1As shown. Additionally, in this embodiment, base station 104 may also include a ground station (not shown) for communication to the backhaul network. UE 102 may be implemented as an electronic device configured to operate based on a variety of wireless communication technologies. These technologies may include, but are not limited to, technologies based on 3GPP standards. For example, UE 102 may be configured to operate using one or more 3GPP versions (such as version 15 (Rel-15), version 16 (Rel-16), version 17 (Rel-17), version 18 (Rel-18), and / or other 3GPP versions). UE 102 may include, but is not limited to, wireless communication devices, smartphones, laptops, desktop computers, tablets, personal assistants, monitors, televisions, wearable devices, Internet of Things (IoT) devices, and vehicle communication devices. Base station 104 may include one or more nodes configured to operate based on a variety of wireless communication technologies (such as, but not limited to, technologies based on 3GPP standards). For example, base station 104 may include nodes configured to operate using Rel-15, Rel-16, Rel-17, Rel-18, or other 3GPP versions. Base station 104 may include, but is not limited to, satellites, high-altitude platforms (HAPs) (such as hot air balloons), airborne base stations, unmanned aerial vehicles (UAVs), NodeBs, eNodeBs, gNBs, new radio base stations (NR BSs), access points (APs), remote radio heads, relay stations, etc.

[0026] In some aspects, UE 102 is connected to base station 104 via communication link 106. Communication link 106 may include uplink (UL) and downlink (DL) connections. In some aspects, UE 102 may enter sleep mode to conserve power and wake up when communication from base station 104 is desired. For example, base station 104 may send a paging message to UE 102 via communication link 106. The paging message may indicate subsequent communication, such as telephone calls and / or data transmission. Therefore, when UE 102 receives a paging message, UE 102 may wake up to receive additional communication via communication link 106. In some aspects, UE 102 may wake up during paging times to check whether paging messages have been sent and received. Furthermore, UE 102 may need to wake up periodically to receive SSB signals to keep UE 102 synchronized with base station 104 so that UE 102 can receive signals during paging times.

[0027] In some respects, to further conserve energy for receiving SSB signals and checking the paging time when there is no paging message to be sent by base station 104, base station 104 may send a PEI to UE 102 indicating whether to send a paging message in the next paging time. When the PEI indicates that there is no paging message to be sent in the next paging time, UE 102 can further conserve energy by avoiding receiving SSB signals and avoiding checking the next paging time.

[0028] In some respects, UE 102 is served by an NTN wireless network (such as System 100). Base station 104 may allocate a tight link budget to UE 102 because base station 104 has limited energy and serves multiple UEs, including UE 102. For example, base station 104 may include a battery-powered satellite that can be charged by solar panels. To transmit to each of the multiple UEs, the satellite may need to form a beam to point at each of the multiple UEs, which consumes energy. Therefore, the satellite may allocate a tight link budget to each of the multiple UEs, including UE 102. Thus, the signal power of the communication signal from BS 104 can be reduced to conserve energy. In some respects, UE 102 can be placed in a pocket or backpack. For example, the user of UE 102 may be traveling in mountainous areas, and the user may place UE 102 inside a pocket or backpack to prevent damage to UE 102. Furthermore, terrestrial networks provided by cell towers may be unavailable in mountainous areas, and therefore UE 102 connects to the NTN wireless network via base station 104. However, due to the limited link budget assigned to UE 102, the UE may be unable to receive signals from base station 104 when placed in a pocket or backpack. For example, due to signal degradation caused by the pocket or backpack, the signal carrying the paging message may be too weak for UE 102 to decode. In this case, base station 104 can send a paging warning to UE 102 before sending the paging message, allowing UE 102 to notify the user to physically remove UE 102 from the bag or backpack. For example, base station 104 can use higher power to send the paging warning, allowing the paging warning to penetrate the pocket or backpack. Alternatively, base station 104 can use a more robust modulation and decoding configuration to send the paging warning, allowing UE 102 to recover and decode the paging warning with weak signal strength. After receiving the paging warning, the UE can determine that it is in a location where the signal strength of the received signal from the base station is too low to receive the paging message. In this case, the UE can generate a notification to the user, allowing the user to physically move the UE to a different location to improve signal strength. In some cases, a notification may indicate that the signal strength is too low and action is required. In others, a notification may indicate that the UE needs to physically move to a different location to obtain better signal reception. In either case, the notification should at least prompt the user to remove the UE from their pocket or backpack to check the notification. The notification can be an audio message, a series of vibrations, and / or a text message. After the user physically moves the UE, the UE may receive a subsequent paging message and wake up to receive further communications.

[0029] Figure 2A block diagram illustrating an electronic device 200 implementing paging warnings according to some aspects of this disclosure is shown. Electronic device 200 can be any electronic device in the electronic devices of system 100 (e.g., UE 102 and base station 104).

Moreover, although the system of electronic device 200 is illustrated as a separate component, aspects of this disclosure may include any combination of these components (e.g., fewer or more components).

[0030] Memory 250 may include random access memory (RAM) and / or cache, and may include control logic (e.g., computer software) and / or data. Memory 250 may include other storage devices or memories. According to some examples, operating system 252 may be stored in memory 250. Operating system 252 can manage data transfer from memory 250 and / or one or more applications 254 to processor 210 and / or transceiver 220. In some examples, operating system 252 holds one or more network protocol stacks (e.g., Internet Protocol stack and cellular protocol stack, etc.) that may include multiple logical layers. At the corresponding layer of the protocol stack, operating system 252 includes control mechanisms and data structures to perform the functions associated with that layer.

[0031] According to some examples, application 254 may be stored in memory 250. Application 254 may include applications used by electronic device 200 and / or users of electronic device 200 (e.g., user applications). Applications in application 254 may include, but are not limited to, applications such as, but not limited to, wireless streaming, video streaming, remote control applications, and / or other user applications. In some aspects, device capability 256 may be stored in memory 250.

[0032] Electronic device 200 may also include communication infrastructure 240. Communication infrastructure 240 provides communication between, for example, processor 210, transceiver 220, and memory 250. In some embodiments, communication infrastructure 240 may be a bus.

[0033] Transceiver 220 transmits and receives communication signals, including conventional reference signals and other data communication signals. Additionally, transceiver 220 transmits and receives communication signals that support mechanisms for measuring communication links, generating and transmitting system information, and receiving system information. According to some aspects, transceiver 220 may be coupled to antenna 260 to wirelessly transmit and receive these communication signals. Antenna 260 may include one or more antennas, which may be of the same or different types and may form one or more antenna ports. Transceiver 220 enables electronic device 200 to communicate with other devices, which may be wired and / or wireless. In some examples, transceiver 220 may include a processor, controller, radio component, socket, plug, buffer, and similar circuitry / devices for connecting to and communicating over a network. According to some examples, transceiver 220 includes one or more circuitry for connecting to and communicating over wired and / or wireless networks.

[0034] Additionally, transceiver 220 may include one or more circuits (including a cellular transceiver) for connecting to and communicating over a cellular network. The cellular network may include, but is not limited to, 3G / 4G / 5G networks, such as Universal Mobile Telecommunications System (UMTS) and Long Term Evolution (LTE). For example, transceiver 220 may be configured to operate according to one or more of the 3GPP standards Rel-15, Rel-16, Rel-17, Rel-18, or other versions.

[0035] Furthermore, one or more transceivers may include one or more circuits for connecting to and communicating with a satellite network. Such satellite networks may include, but are not limited to, wireless communication networks such as 3G / 4G / 5G networks, Universal Mobile Telecommunications System (UMTS), Long Term Evolution (LTE), and specific satellite communication network protocols for gateway and control functions from satellite ground stations. For example, one or more transceivers 220 may be configured to operate according to one or more of the 3GPP standards Rel-15, Rel-16, Rel-17, Rel-18, or other versions. Additionally, for LEO (Low Earth Orbit) type satellites, the additional capability of directing the beam to a fixed point on the Earth's surface via beamforming or mechanically steerable beaming methods is provided.

[0036] The following text is about Figures 3 to 8 In more detail, processor 210 can implement different mechanisms for paging alerts, such as those related to... Figure 1The system 100 discussed herein. For example, in some embodiments, memory 250 may store instructions that, when executed by processor 210, cause processor 210 to perform or cause electronic device 200 to perform the operations described herein, such as supporting a paging alert mechanism in an NTN wireless network. Alternatively, processor 210 may be "hard-decoded" to perform or cause to perform the operations described herein. In some embodiments, processor 210 may be configured to perform or cause to perform Figures 3 to 7 The operations described in [the document].

[0037] Figure 3 Example 300 illustrates a paging warning mechanism. Example method 300 is provided for illustrative purposes only and does not limit the aspects disclosed. For convenience, not limitation, Figure 3 About Figure 1 , Figure 2 and Figure 8 The elements are used to describe it. Example 300 may represent an electronic device that implements a paging warning mechanism (e.g., Figure 1 The operation of UE 102 and base station 104. Example 300 can also be provided by Figure 2 Electronic device 200 (controlled or implemented by processor 210) and / or Figure 8 The computer system 800 executes the method. However, the example method 300 is not limited to the specific aspects depicted in the figures, and other systems can be used to execute the method, as those skilled in the art will understand. It should be understood that not all operations may be necessary, and these operations may not be performed in accordance with the instructions provided. Figure 3 Perform them in the same order as shown.

[0038] In some respects, Example 300 illustrates, from left to right, the timer sequence that can be generated by the UE (such as...) Figure 1 UE 102) from base station (such as Figure 1The signals received by the base station 104. For example, the signals include SSB signals 302a, 302b, and 302c, paging signal 304, Physical Downlink Control Channel (PDCCH) signal 306, and Physical Data Sharing Channel (PDSCH) signal 308. In some aspects, paging signal 304 may include a PEI, a paging warning, or both. When paging signal 304 includes a PEI, the PEI indicates whether the paging message should be received in the next paging time. For example, the next paging time may be the period when PDSCH signal 308 is received. When the PEI indicates that the paging message should be received in PDSCH signal 308, UE 102 may detect and receive information about the paging message in PDCCH signal 306. In some aspects, this information includes the time position of the paging message within PDSCH signal 308. This information may also include decoding configurations for the paging message, such as modulation configurations, decoding configurations, and other configurations of the paging message, to enable the UE to decode the paging message. In some respects, paging messages can indicate additional communications from the base station, such as telephone calls and additional data transmissions. The UE can be woken up based on the paging message to receive these additional communications.

[0039] In some respects, the PEI can indicate a group of UEs for which it is expected. For example, the PEI may include a group indicator corresponding to a group of UEs that includes that UE. When a UE receives a PEI, it can determine whether the PEI includes a group indicator. If it does not include a group indicator, the UE can determine that no paging message will be received in the next PDSCH signal 308 and can return to power-saving mode or sleep mode. If the UE determines that the PEI includes a group indicator, the UE can maintain synchronization by receiving SSB signals 302b and 302c and receive PDCCH signal 306. In this case, the information included in PDCCH signal 306 can indicate which UE in the group should receive the paging message. For example, this information can indicate the UE identifier (ID). If the UE ID corresponds to the UE, the UE can receive PDSCH signal 308 and detect the paging message based on this information. Otherwise, the UE can return to power-saving mode or sleep mode. When a UE is not the intended recipient of a paging message, it has already expended energy receiving SSB signals 302b and 302c to maintain synchronization when no paging message is to be received in PDSCH signal 308. Therefore, a PEI may be a false alarm. In summary, when a UE in a group expects a paging message, other UEs in that group may expend additional energy without receiving the paging message. In some respects, a PEI can indicate a UE subgroup with fewer UEs compared to the main group. In this case, the UE is less likely to expend energy when no paging message is to be received.

[0040] In some aspects, the UE can maintain synchronization with the base station during period 310 when a paging message is to be received. For example, the UE can synchronize its time with the base station's time based on SSB signals 302a, 302b, and 302c. By receiving SSB signal 302a, the UE can correctly receive paging signal 304. Furthermore, when paging signal 304 includes a PEI indicating an upcoming paging message in PDSCH signal 308, the UE can maintain synchronization by receiving SSB signals 302b and 302c to correctly receive information about the paging message in PDCCH signal 306, and subsequently correctly receive the paging message in PDSCH signal 308. In some aspects, the UE is configured with period 312, which indicates the time interval between the first frame of paging signal 304 and the first frame of PDCCH signal 306. In this case, when the UE is synchronized, the UE knows the time position of PDCCH signal 306. Period 312 may also be referred to as frame offset and is configured based on the number of frames. For example, period 312 can be configured for up to 16 frames, such as 160 ms. In other respects, when the PEI indicates that no paging message is to be received in the subsequent PDSCH signal (such as PDSCH signal 308), the UE can avoid performing synchronization and does not need to receive at least SSB signals 302b and 302c. In this case, the UE can save energy that would otherwise be used to detect and receive SSB signals and perform synchronization during period 312.

[0041] In some respects, paging signal 304 may include a paging warning instead of PEI. A paging warning can similarly indicate whether the paging message in PDSCH 308 should be received. Furthermore, a paging warning can trigger the UE to notify the user of the UE's physical movement. For example, the UE may be operating in an NTN wireless network, and the base station communicates with the UE via satellite. In this case, the UE may be assigned a tight link budget, and any additional signal degradation besides path loss may render the signal undetectable to the UE. For example, the UE may be placed in a pocket or backpack when the signal is sent to it. After experiencing path loss, a signal that is otherwise detectable by satellite may be further degraded by the pocket or backpack and become undetectable to the UE. The signal may include PDCCH signal 306 and PDSCH signal 308. In this case, the UE may be unable to receive the paging message and therefore unable to wake up to receive further communication, as discussed above. To address this issue, a paging warning can trigger the UE to notify the user of the UE's physical movement. For example, compared to PDCCH signal 306 and PDSCH signal 308, a higher power and / or a more robust modulation and decoding scheme can be used to transmit the paging signal 304, which includes a paging warning. Therefore, the UE can still receive the paging signal 304 even when it is placed in a pocket or backpack. When the UE receives a paging warning included in the paging signal 304, and the paging warning indicates that the paging message should be received in the PDSCH signal 308, the UE can notify the user to physically move the UE, for example, outside a pocket or backpack, so that the UE can receive PDCCH signal 306 and PDSCH signal 308 to retrieve the paging message. For example, after receiving the paging warning, the UE can determine that it is in a location where the signal strength of the received signal from the base station is too low to receive the paging message. In this case, the UE can generate a notification to the user, allowing the user to physically move the UE to a different location to improve signal strength. In some aspects, the notification may indicate that the signal strength is too low and action is needed. In other aspects, the notification may indicate that the UE needs to physically move to a different location to obtain better signal reception. In either case, the notification should at least prompt the user to remove the UE from their pocket or backpack to check it. In some respects, the notification can be sound, a series of vibrations, and / or a text message.

[0042] In some respects, the PDCCH signal 306 may be repeatedly transmitted before the PDSCH signal 308. For example, the base station may periodically transmit the PDCCH signal 306 N times. In this case, the UE is more likely to detect information about the paging message in at least one of the N transmissions. For example, as mentioned above, the UE may be assigned a tight link budget, and therefore the UE may not be able to receive one or more of the N transmissions of the PDCCH signal 306. However, if the UE can receive at least one of the N transmissions of the PDCCH signal 306, the UE can use this information to receive the paging message carried in the PDSCH signal 308. Furthermore, the base station may repeatedly transmit paging warnings. For example, the UE may be in an area with weak signal reception, and the UE may fail to detect a paging warning. In this case, the UE may request the base station to repeatedly transmit the paging warning so that the UE can detect the paging warning.

[0043] In some respects, when paging signal 304 includes a paging warning, the period 312 is longer than when paging signal 304 includes a PEI. For example, as discussed above, period 312 can be as long as 16 frames or 160 ms. Therefore, when paging signal 304 includes a PEI, the UE has up to 160 ms to prepare to receive PDCCH signal 306. However, when paging signal 304 includes a paging warning, the UE requires more time. This is because a paging warning allows the UE to notify the user of the physical movement of the UE. For example, the UE may be placed in a pocket or backpack. In this case, period 312 needs to be long enough for the user to find and physically move the UE, which could be several seconds. As another example, the UE may be in a location where the LosS to the satellite is blocked by trees or other obstacles. Therefore, the user may need to physically move to a new location where there are no leaves on a hillside or mountaintop. In this case, the user may need several minutes to move the UE to the new location. In some respects, the base station may configure the UE with period 312. In addition, the UE can report the length of period 312 to the base station, and the base station can grant or adjust the reported length.

[0044] In some respects, paging warnings can be configured to be received in addition to, rather than replacing, the PEI. For example, the base station can send one or more repeated paging warnings after the PEI. In this case, the UE can receive both the PEI and one or more paging warnings. As discussed above, the period 312 can be configured differently for the PEI and the paging warnings. Thus, the PEI and the paging warning can correspond to their respective PDCCH signals 306. For example, the PEI can correspond to the PDCCH signal 306 to be received 100ms after the PEI is received. Thus, the UE can check and receive information about the paging message in the PDCCH signal 306 100ms after receiving the PEI. If the PEI indicates that no paging message is to be received, the UE does not immediately return to power-saving mode or sleep mode. Instead, the UE continues to receive one or more paging warnings. One or more paging warnings can correspond to the PDCCH signal 306 to be received 10 seconds after the one or more paging warnings are received. If one or more paging warnings indicate that a paging message is to be received, the UE triggers a notification to the user to physically move the UE, and maintains synchronization after 10 seconds to receive PDCCH signal 306. Otherwise, if one or more paging warnings indicate that no paging message is to be received, the UE returns to power-saving mode or sleep mode. In summary, when both PEI and paging warnings are configured, the UE can check both before returning to power-saving mode or sleep mode.

[0045] In some respects, a base station may send more than one paging message to a UE over a prolonged period, such as 10 seconds. For example, if the base station configures the UE with a PEI and one or more paging warnings as discussed above, the base station may send a first paging message corresponding to the PEI and a second paging message corresponding to one or more paging warnings. The UE may receive the first paging message based on the PEI and may also receive the second paging message based on at least one of the one or more paging warnings. In some respects, the base station may send the second paging message over a prolonged period, such as 10 seconds, after sending the first paging message. This may be because it may take a long time, such as 10 seconds, for the user to physically move the UE based on one or more paging warnings. In some respects, the first paging message and the second message may be similar or identical. For example, both the first paging message and the second message may indicate the same additional communication, such as an incoming call. Therefore, even if the UE misses the first paging message, the UE can still wake up to receive additional communication based on the second paging message. In other respects, the first paging message and the second message may be different. For example, a first paging message may correspond to a first telephone call, and a second paging message may correspond to a second telephone call.

[0046] Figure 4Example method 400 illustrates an example method for a UE to operate based on a paging warning according to various aspects of this disclosure. Example method 400 is provided for illustrative purposes only and does not limit the aspects disclosed. It is provided for convenience, not limitation. Figure 4 About Figure 1 , Figure 2 and Figure 8 The elements are used to describe it. Example method 400 represents an electronic device that implements paging alert operations (e.g., Figure 1 The operation of UE 102). Example method 400 can also be performed by Figure 2 Electronic device 200 (controlled or implemented by processor 210) and / or Figure 8 The example method 400 is executed by a computer system 800. However, the example method 400 is not limited to the specific aspects depicted in the figures, and other systems can be used to execute the method, as those skilled in the art will understand. It should be understood that not all operations may be necessary, and these operations may not be performed in accordance with... Figure 4 Perform them in the same order as shown.

[0047] At position 402, the UE receives data from the base station (such as...). Figure 1 Base station 104 in the cell receives configuration messages. In some respects, the configuration messages are cell-specific. Therefore, UEs (including UEs) within the same cell share the same configuration messages. In other respects, the configuration messages are UE-specific. In either case, the configuration message may indicate the number of times the paging warning is repeated and the number of times the PDCCH signal is repeated. As mentioned above... Figure 3 As discussed herein, the base station may repeatedly transmit paging warnings and / or PDCCH signals to increase the chances of the UE receiving paging messages during subsequent transmissions (such as PDSCH signals). In some aspects, paging warning repetitions may occur in consecutive time slots or in time slots separated by constant intervals. For example, time slots separated by constant intervals may occur in a common CORESET within Control Resource Set #0 (CORESET #0) or System Information Block 1 (SIB1). In some aspects, each paging warning repetition in a paging warning repetition includes the same content of the paging warning.

[0048] In some aspects, the configuration message can also indicate a first reference signal received power (RSRP) threshold for triggering paging warning repetition. For example, the UE can continuously monitor the RSRP of signals received from the base station (such as SSB signals). When the RSRP is below the first RSRP threshold, the UE can determine that paging warning repetition is needed so that the UE can successfully receive the paging warning. In this case, the UE can report the need for paging warning repetition to the base station, and the base station can configure the UE to have paging warning repetition enabled. Furthermore, the UE can determine whether the number of paging warning repetitions indicated by the configuration message is appropriate. For example, the RSRP may be so low that the UE may need at least X paging warning repetitions to successfully receive the paging warning, where X could be, for example, 20. Alternatively, when the RSRP is within a range, the UE can determine that at least X paging warning repetitions are needed. This range can be between the first RSRP threshold and a lower limit of RSRP below the first RSRP threshold. In this example, the configuration message could indicate 10 paging warning repetitions, meaning the base station will repeatedly send the paging warning 10 times instead of 20 times. In this case, the UE can report to the base station to adjust the number of paging warning repetitions to 20. In some respects, the UE may report the need for repeated paging warnings and the number of times a paging warning is repeated via Radio Resource Control (RRC) signaling and / or MAC Control Element (MACCE) signaling.

[0049] In some aspects, the configuration message can also indicate a second RSRP threshold to trigger the UE to notify the user of physically moving the UE. As discussed above, the UE can be placed in a pocket or backpack, thus blocking signals from the base station. This is in contrast to other signals (such as...) Figure 3 Compared to the PDCCH signal 306 and PDSCH signal 308, the UE can use higher power or a more robust modulation and decoding scheme to send paging warnings. When the RSRP is below the second RSRP threshold, the UE can receive paging warnings, but cannot receive other signals. In this case, the UE triggers a notification to the user to physically move the UE, which allows the RSRP to be increased and other signals to be received.

[0050] In some respects, configuration messages can also indicate the time interval between paging warnings and PDCCH signals carrying information about paging messages, such as Figure 3The period 312 in the configuration message. In some aspects, the UE can determine whether the time interval indicated by the configuration message is appropriate. For example, the UE can determine that the RSRP is so low that it may take at least 20 seconds for the user to physically move the UE to a location where the RSRP is higher than a second RSRP threshold. However, the configuration message indicates a time interval of 10 seconds. In this case, the UE can report to the base station that a 20-second time interval is needed. In other words, the UE can report to the base station that a second time interval longer than the pre-configured first time interval is needed. The base station can adjust the time interval to 20 seconds. As another example, the UE can monitor the user's behavior to determine the time interval to a user-specific value. Specifically, the UE can record the historical period required for the user to physically move the UE. For example, the first user may be alert and constantly pay attention to the UE and its various notifications. Therefore, the historical period may be small because the first user may be able to react quickly to notifications from the UE. In this case, the UE can determine the required time interval to be a smaller value. The second user may be easily distracted and therefore will not pay close attention to notifications from the UE, or will not react immediately even after noticing the notification. Therefore, the historical period may be large. In this case, the UE can determine the required time interval to be a larger value. In some respects, the time gap can be the period between a paging warning and a paging message. In this case, the time gap also includes the period of the PDCCH signal (such as PDCCH signal 306).

[0051] In some aspects, configuration messages can indicate time intervals as the number of frames. For example, a configuration message could indicate a time interval of 200 frames, or 2 seconds. In some aspects, configuration messages can indicate time intervals using absolute time. For example, a configuration message could indicate a time interval of 2 seconds. In some aspects, configuration messages can also indicate time intervals by adding an additional period to the predetermined maximum interval period of the PEI. For example, as discussed above, time intervals for the PEI (such as...) Figure 3 The period (312) has a maximum gap period of 16 frames or 160 ms. The paging warning time interval is longer than the maximum gap period. Therefore, the configuration message can indicate an additional period based on the maximum gap period. For example, the configuration message can indicate 500 ms. Therefore, the paging warning time interval is 160ms + 500ms = 660ms.

[0052] In some respects, time gaps can be predefined values ​​rather than indicated by configuration messages. For example, a time gap can be predetermined to be 10 seconds. In some respects, time gaps can be configured via signaling from the base station, such as configuration messages. For example, the base station can send configuration messages via cell-specific signals, such as SIB signals and RRC signals. Alternatively, the base station can send configuration messages via UE-specific signals, such as dedicated RRC signals and MAC CE signals. In some respects, the base station can dynamically indicate time gaps. For example, the base station can configure one or more candidate time gaps via downlink signaling, such as UE-specific signals including SIB signals. Each of the one or more candidate time gaps can correspond to an index. In this case, paging warnings can indicate time gaps by including or indicating the index. For example, when a paging warning is a new downlink control information (DCI) format, DCI form 2_7, or other DCI formats discussed below, the paging warning can include an index in the payload. When a paging warning is a sequence as discussed above, the index can be part of the sequence generation initialization value. In either case, the UE can determine the time interval based on the index after extracting the index from the paging warning.

[0053] In some respects, the number of paging warning repetitions can be predefined or configured, similar to the time intervals discussed above. For example, the number of paging warning repetitions can be a predefined value, such as 10 times. Alternatively, the number of paging warning repetitions can be configured via UE-specific signals (such as SIB and RRC signals) and / or via UE-specific signals (such as dedicated RRC and MAC CE signals). In some respects, the UE can report its ability to receive paging warning repetitions. For example, the UE can report whether it can monitor and receive paging warning repetitions. If the UE reports that it cannot receive paging warning repetitions, the base station can choose not to configure paging warning repetitions for the UE. Otherwise, the base station can configure paging warning repetitions for the UE.

[0054] In some respects, the number of times the PDCCH signal is repeated can be predefined or configured, similar to the time intervals discussed above. For example, the number of times the PDCCH signal is repeated can be a predefined value, such as 10 times. As another example, the number of times the PDCCH signal is repeated can be configured via UE-specific signals (such as SIB signals and RRC signals) and / or via UE-specific signals (such as dedicated RRC signals and MAC CE signals). In some respects, the number of times the PDCCH signal is repeated can be dynamically indicated. For example, the base station can preconfigure the UE with multiple possible repetition values. The base station can preconfigure the UE via SIB signals. In some respects, each possible repetition value can correspond to an index. Therefore, the base station can indicate to the UE the selected repetition value from the possible repetition values ​​for use, without having to include the selected repetition value itself in the signaling. For example, a paging warning can include the index of the selected repetition value. In other respects, a paging warning can include the selected repetition value itself in the paging warning payload. When paging warnings are sequential, the base station can also generate paging warnings based on a selected repetition value as part of the sequence generation initialization value. In some aspects, the number of PDCCH signals can be implicitly indicated. For example, the number of PDCCH signals can be the same as the number of paging warning repetitions. For instance, when the base station configures 10 paging warning repetitions, the UE can assume that 10 PDCCH signal repetitions are also configured. Furthermore, the number of PDCCH signal repetitions can correspond proportionally to the number of paging warning repetitions. For example, the number of PDCCH signal repetitions can be twice the number of paging warning repetitions. In some aspects, the UE can be configured with a mapping table indicating the mapping rules between the number of PDCCH signal repetitions and the number of paging warning repetitions. The UE can use the mapping table to look up the number of PDCCH signal repetitions based on the number of paging warning repetitions.

[0055] At position 404, the UE receives a paging warning. The UE may receive a paging warning without any paging warning repetitions, or in at least one of the paging warning repetitions. In some aspects, the paging warning may indicate the number of times the PDCCH signal is repeated, in addition to or instead of the configuration message. The paging warning may be a new DCI format. For example, the paging warning may be UE-specific. In some aspects, the paging warning may include at least a portion of the UE's ID. For example, the paging warning may include at least a portion of the UE's 5G-S-Temporary Mobile Subscription Identifier (5G-S-TMSI). In some aspects, the paging warning may include Cyclic Redundancy Check (CRC) scrambled with at least a portion of the UE's ID. For example, the UE's ID may be 5G-S-TMSI or a new ID, such as the Paging Warning Radio Network Temporary Identifier (PA-RNTI).

[0056] In some respects, paging warnings can be DCI format 2_7. For example, a paging warning can be a group common DCI, in which a group of UEs share the paging warning. UEs can use their UE IDs to obtain the paging time and UE subgroup based on the paging warning. In some respects, paging warnings may also include CRC scrambled using the Paging Early Indication Radio Network Temporary Identifier (PEI-RNTI).

[0057] In some aspects, paging warnings can be sent based on sequences. For example, the UE's ID can be used to generate the sequence. Specifically, the sequence can be generated based on a modulo operation of the ID. In some aspects, the ID may include 5G-S-TMSI.

[0058] At 406, the UE may generate a notification for the user of the UE. The notification may include sound, a series of vibrations, or a text message. In some aspects, the UE generates the notification when a paging warning received in step 404 instructs the UE. For example, the paging warning may be a new DCI format, and the paging warning indicates the ID of the UE. Alternatively, the paging warning may be a DCI format 2_7 indicating a group of UEs, and this group of UEs includes UE 2_7. Specifically, the paging warning may include a bit corresponding to the group of UEs, and this bit is set to 1. Again, the paging warning may be a sequence indicating the ID of the UE. In some aspects, when a paging warning instructs the UE, the UE further considers whether other conditions are met to notify the user. For example, other conditions may include RSRP measurement. Specifically, the UE may monitor and measure the RSRP of received signals (such as demodulation reference signals (DMRS) or SSB signals). If the RSRP is below a trigger threshold, similar to the second RSRP threshold discussed above, the UE may determine to trigger a notification to the user. In some aspects, the trigger threshold may correspond to the aggregation level of the PDCCH. The aggregation level defines the granularity of PDCCH resource allocation. Specifically, one or more Physical Resource Blocks (PRBs) are aggregated together as Control Channel Elements (CCEs) and assigned together. Therefore, the aggregation level of a PDCCH corresponds to the number of PRBs aggregated to be assigned together by the PDCCH. Here, the base station or UE can determine that a higher aggregation level results in a higher trigger threshold. The trigger threshold can be configured by the base station via signaling (such as the configuration message in 402). In some aspects, in addition to or instead of RSRP measurement, other conditions may include the UE's elevation angle. For example, the UE can measure and determine its elevation angle to the base station. If the elevation angle is less than a threshold angle, the UE can determine to trigger a notification to the user. This is because when the elevation angle is small, path loss is large, and the UE may need to physically move to a different location to correctly receive paging messages. Similar to the trigger threshold, the threshold angle can also be configured by the base station via signaling (such as the configuration message in 402).

[0059] At 408, the UE receives information about the paging message. In some aspects, the UE receives this information via PDCCH signals (such as...). Figure 3 The UE receives information via the PDSCH signal 306. In some aspects, this information includes the time position of the paging message within the PDSCH signal (such as PDSCH signal 308). This information may also include the decoding configuration of the paging message, such as the modulation configuration, decoding configuration, and other configurations of the paging message, to enable the UE to decode the paging message.

[0060] At 410, the UE receives the paging message based on the information in the paging message. For example, the paging message may be included in the PDSCH signal (such as...). Figure 3 In the PDSCH signal 308, the UE can determine the time and location of the paging message to receive it, and decode the paging message based on the decoding configuration included in the information of the paging message received via the PDCCH signal. In some aspects, the paging message indicates additional communication from the base station, including telephone calls and data transmissions. The UE can be woken up based on the paging message to receive additional communication.

[0061] Figure 5 Example method 500 for a UE to operate based on a short message according to various aspects of this disclosure is illustrated. In some aspects, the short message may be part of DCI signaling transmitted on the PDCCH. For example, a short message may be defined according to Section 6.5 of 3GPP TS 38.331v. 17.2.0. Example method 500 is provided for illustrative purposes only and is not intended to limit the aspects disclosed. For convenience and not limitation, Figure 5 About Figure 1 , Figure 2 and Figure 8 The elements are used to describe it. Example method 500 could represent an electronic device that receives a paging warning (e.g., Figure 1 The operation of UE 102). Example method 500 can also be performed by Figure 2 Electronic device 200 (controlled or implemented by processor 210) and / or Figure 8 The example method 500 is executed by a computer system 800. However, the example method 500 is not limited to the specific aspects depicted in the figures, and other systems can be used to execute the method, as those skilled in the art will understand. It should be understood that not all operations may be necessary, and these operations may not be performed in accordance with... Figure 5 Perform them in the same order as shown.

[0062] At position 502, the UE receives a configuration message from the base station. In some respects, the configuration message is similar to... Figure 4The configuration messages discussed in section 402. For example, the configuration messages here may indicate the number of times the PDCCH signal is repeated. The configuration messages may also indicate an RSRP threshold to trigger the UE to notify the user of physical UE movement. Furthermore, the configuration messages may indicate the time interval between the short message and the PDCCH signal carrying information about the paging message, such as... Figure 3 The cycle is 312. In some aspects, the UE can determine its ability to receive PDCCH signal repetitions and the desired number of PDCCH signal repetitions and report them to the base station, such as regarding... Figure 4 The ability to receive repeated paging warnings and the number of paging warning repetitions are discussed similarly in section 402. For example, the UE may report to the base station that it cannot detect and receive repeated PDCCH signals. In this case, the base station can avoid configuring multiple PDCCH signal repetitions for the UE. As another example, the UE may report to the base station that it can detect and receive repeated PDCCH signals and requires X repeated PDCCH signals. In this case, the base station can configure X repeated PDCCH signals for the UE.

[0063] At position 504, the UE receives a short message. In some aspects, the short message may include a CRC scrambled by the UE's ID. For example, the UE's ID may be the UE's PA-RNTI. Therefore, the UE can determine whether the short message indicates the UE. For example, if the UE determines that the CRC is scrambled by the UE's ID, the UE can determine that the short message indicates the UE. Otherwise, the UE ignores the short message. Furthermore, the short message may include bits indicating whether the short message serves as a paging warning. For example, this bit may be the fifth bit of the short message or some other bit in the short message. Therefore, when the UE determines that the short message indicates the UE and that the short message serves as a paging warning, the UE determines that the paging message should be received in the upcoming signal.

[0064] At position 506, the UE can generate notifications to its users. (As mentioned above...) Figure 4 As discussed in the article, the UE needs to receive PDCCH signals (such as...). Figure 3 PDCCH signal 306) and PDSCH signal (such as Figure 3The UE decodes the PDSCH signal (308) in the received signal to detect and receive subsequent paging messages. However, the UE may be placed in a pocket or backpack to prevent the UE from detecting and receiving the PDCCH and PDSCH signals. In this case, when the UE determines that a paging message is to be received in the upcoming signal (e.g., the PDCCH and PDSCH signals), the UE may generate a notification to the user to inform the user to physically move the UE. For example, the notification may inform the user to physically move the UE out of the pocket or backpack. Alternatively, the notification may inform the user to physically move to a different location with better signal reception. In some aspects, the UE may further determine whether to generate a notification based on the RSRP of the received signal and / or the elevation angle to the base station, as in... Figure 4 The same discussion is made in section 406.

[0065] At point 508, the UE receives information about the paging message. In some aspects, the UE receives this information via PDCCH signals (such as...). Figure 3 The UE receives information via the PDSCH signal 306. In some aspects, this information includes the time position of the paging message within the PDSCH signal (such as PDSCH signal 308). This information may also include the decoding configuration of the paging message, such as the modulation configuration, decoding configuration, and other configurations of the paging message, to enable the UE to decode the paging message.

[0066] At point 510, the UE receives and decodes the paging message based on its information. For example, the paging message may be included in the PDSCH signal (such as...). Figure 3 In the PDSCH signal 308, the UE can determine the time and location of the paging message to receive it, and decode the paging message based on the decoding configuration included in the information in the paging message. In some aspects, the paging message indicates additional communication from the base station, including telephone calls and data transmissions. The UE can be woken up based on the paging message to receive additional communication.

[0067] Figure 6 An example method 600 is illustrated for a UE to operate using paging warnings according to various aspects of this disclosure. The example method 600 is provided for illustrative purposes only and is not intended to limit the aspects disclosed. It is provided for convenience, not limitation. Figure 6 About Figure 1 , Figure 2 and Figure 8 The elements are used to describe it. Example method 600 can represent an electronic device (e.g., Figure 1 The operation of UE 102). Example method 600 can also be performed by Figure 2 Electronic device 200 (controlled or implemented by processor 210) and / or Figure 8The example method 600 is executed by a computer system 800. However, the example method 600 is not limited to the specific aspects depicted in the figures, and other systems can be used to execute the method, as those skilled in the art will understand. It should be understood that not all operations may be necessary, and these operations may not be performed in accordance with... Figure 6 Perform them in the same order as shown.

[0068] At point 602, the UE receives a paging warning from the base station. In some aspects, the paging warning may be directed to the UE. For example, the paging warning may include at least a portion of the UE's ID. Alternatively, the paging warning may include a CRC sequence scrambled based on at least a portion of the UE's ID. Yet another example is that the paging warning may be generated based on the UE's ID. In any of the above cases, the UE may determine that the paging warning is directed to the UE.

[0069] At 604, the UE generates a notification to its user. In some aspects, the UE generates a notification when it determines that a paging warning is instructing the UE, as discussed above at 602. Furthermore, the UE may further generate the notification based on the RSRP and / or elevation angle of the signal. For example, the UE may generate a notification for the user when it determines that the RSRP of the signal received from the base station is below a threshold and / or the elevation angle to the base station is less than a threshold angle. In some aspects, the notification may inform the UE's user to physically move the UE. For example, the notification may inform the user to physically move the UE out of a pocket or backpack. As another example, the notification may inform the user to physically move to a location with better signal reception, such as high ground with a LoS to a satellite connected to the base station. In some aspects, the notification may be an audio notification to the UE's user, a vibration notification to the UE's user, and / or a text notification to the UE's user.

[0070] At position 604, the UE receives and decodes the paging message. (As mentioned above...) Figure 4 and Figure 5 Similarly discussed in the text, the UE can detect and receive information about PDCCH signals (such as...). Figure 3 The paging message is contained in the PDSCH signal (such as PDSCH signal 306). This information may include the time position of the paging message within the PDSCH signal (such as PDSCH signal 308). This information may also include the decoding configuration of the paging message, such as the modulation configuration, decoding configuration, and other configurations of the paging message, to enable the UE to decode the paging message. The UE can then receive the paging message based on the information in the paging message. For example, the paging message may be contained in the PDSCH signal (such as PDSCH signal 308). Figure 3In the PDSCH signal 308, the UE can determine the time and location of the paging message to receive it, and decode the paging message based on the decoding configuration included in the information in the paging message. In some aspects, the paging message indicates additional communication from the base station, including telephone calls and data transmissions. The UE can be woken up based on the paging message to receive additional communication.

[0071] Figure 7 An example method 700 for a base station to operate using paging warnings according to various aspects of this disclosure is illustrated. The example method 700 is provided for illustrative purposes only and is not intended to limit the aspects disclosed. It is for convenience, not limitation. Figure 7 About Figure 1 , Figure 2 and Figure 8 The elements are used to describe it. Example method 700 can represent an electronic device (e.g., Figure 1 The operation of base station 104). Example method 700 can also be performed by Figure 2 Electronic device 200 (controlled or implemented by processor 210) and / or Figure 8 The example method 700 is executed by a computer system 800. However, the example method 700 is not limited to the specific aspects depicted in the figures, and other systems can be used to execute the method, as those skilled in the art will understand. It should be understood that not all operations may be necessary, and these operations may not be performed in accordance with... Figure 7 Perform them in the same order as shown.

[0072] At point 702, the base station generates a paging warning. The paging warning may be directed to a UE served by the base station. For example, the paging warning may include at least a portion of the UE's ID. Alternatively, the paging warning may include a CRC sequence scrambled based on at least a portion of the UE's ID. Yet another example is that the paging warning may be generated based on the UE's ID. In any of the above cases, the UE may determine that the paging warning is directed to the UE.

[0073] At point 704, the base station sends a paging warning to the UE. In some aspects, the base station may repeatedly send the paging warning multiple times. Additionally, the base station may send a configuration message to the UE. The configuration message may indicate the number of times the paging warning is repeated. In some aspects, the base station may receive a report from the UE indicating whether the UE can receive repeated paging warnings and / or the desired number of repeated paging warnings. When the report indicates that the UE cannot receive repeated paging warnings, the base station may send a paging warning once instead of multiple times. When the report indicates that the UE can receive repeated paging warnings and requests a certain number of repeated paging warnings, the base station uses the configuration message to configure the UE with the number of repeated paging warnings and sends the paging warning for that number of times.

[0074] At point 706, the base station can utilize PDCCH signals (such as...) before sending paging messages. Figure 3 The PDCCH signal 306 in the PDCCH is used to transmit information for the paging message in the PDCCH. For example, the information may include the paging message in the PDSCH signal (such as...). Figure 3 The time position within the PDSCH signal 308. This information may also include decoding configurations for paging messages, such as modulation configurations, decoding configurations, and other configurations for the paging message, enabling the UE to decode the paging message.

[0075] At point 708, the base station sends a paging message to the UE. In some cases, the base station waits a certain period of time after sending a paging warning before sending the paging message. This period of time can be... Figure 4 The time intervals discussed in the middle and Figure 3 The period 312 in the PDSCH. The base station can send a paging message along with the PDSCH signal in the PDSCH. After sending information about the paging message in the PDCCH in step 706, the base station can subsequently send a PDSCH signal including the paging message based on that information. In some aspects, this period (such as Figure 4 The time intervals discussed in the middle and Figure 3 The period 312 in the PDCCH signal can be the time difference between the first frame of the paging warning and the first frame of the PDCCH signal.

[0076] The computer system 800 may also include one or more secondary storage devices or memories 810. Secondary storage 810 may include, for example, a hard disk drive 812 and / or a removable storage device or drive 814. The removable storage drive 814 may be a floppy disk drive, a magnetic tape drive, an optical disk drive, an optical storage device, a magnetic tape backup device, and / or any other storage device / drive.

[0077] Removable storage drive 814 can interact with removable storage unit 818. Removable storage unit 818 includes a computer-usable or readable storage device on which computer software (control logic) and / or data are stored. Removable storage unit 818 can be a floppy disk, magnetic tape, optical disc, DVD, optical storage disk, and / or any other computer data storage device. Removable storage drive 814 reads from and / or writes to removable storage unit 818 in a well-known manner.

[0078] According to some aspects, secondary storage 810 may include other components, tools, or other methods for allowing computer system 800 to access computer programs and / or other instructions and / or data. Such components, tools, or other methods may include, for example, removable storage unit 822 and interface 820. Examples of removable storage unit 822 and interface 820 may include a program box and box interface (such as an interface present in video game devices), a removable memory chip (such as EPROM or PROM) and associated socket, a memory stick and USB port, a memory card and associated memory card slot, and / or any other removable storage unit and associated interface.
