[0016] Referring to FIG. 1, this figure illustrates a block diagram of one possible, non-limiting example in which embodiments may be implemented. Shown is a user equipment (UE) 110, a radio access network (RAN) node 170, and a network element 190. In the example of FIG. 1, the user equipment (UE) 110 wirelessly communicates with a wireless network 100. The UE is a wireless device capable of accessing the wireless network 100. The UE 110 includes one or more processors 120, one or more memories 125, and one or more transceivers 130 interconnected via one or more buses 127. Each of the one or more transceivers 130 includes a receiver Rx 132 and a transmitter Tx 133. The one or more transceivers 130 may include at least a low-power wake-up receiver and a main receiver. The one or more buses 127 may be an address bus, a data bus, or a control bus, and may include any interconnection mechanism, such as a series of lines on a motherboard or integrated circuit, optical fiber, or other optical communication equipment. A "circuit" may include dedicated hardware or hardware associated with software executable on that hardware. One or more transceivers 130 are connected to one or more antennas 128. One or more memories 125 include computer program code 123. The UE 110 includes a module 140 including one or both of portions 140-1 and / or 140-2, which may be implemented in many ways. The module 140 may be implemented in hardware, for example, as module 140-1 implemented as part of one or more processors 120. The module 140-1 may also be implemented as an integrated circuit or through other hardware such as a programmable gate array. In other examples, the module 140 may be implemented as computer program code 123 and as module 140-2 executed by one or more processors 120. For example, the one or more memories 125 and the computer program code 123 may be configured, by one or more processors 120, to cause the user equipment 110 to perform one or more of the operations described herein.The UE 110 communicates with the RAN node 170 via a wireless link 111 .

[0017] The UE 110 may be capable of sidelink communication with other UEs in addition to network communication or when wireless communication with the network is unavailable or impossible. For example, the UE 110 may perform sidelink communication with other UEs that may include some or all of the features of the UE 110 and / or may include additional features. The UE 110 may communicate with other UEs via short-range communication technologies such as Bluetooth®.

[0018] The RAN node 170 in this example is a base station that provides access to the wireless network 100 by wireless devices such as the UE 110. The RAN node 170 may be, for example, a base station for 5G, also known as New Radio (NR). In 5G, the RAN node 170 may be an NG-RAN node, which is defined as either a gNB or an ng-eNB. A gNB is a node that provides NR user plane and control plane protocol terminations to UEs and connects to the 5GC (e.g., network element 190) via an NG interface. An ng-RAN node may include multiple gNBs, which may also include a central unit (CU) (gNB-CU) 196 and distributed units (DUs) (gNB-DUs), of which the DU 195 is shown. Note that a DU may include a radio unit (RU) or may be coupled to and control the RU. The gNB-CU is a logical node that hosts the RRC, SDAP, and PDCP protocols of a gNB or the RRC and PDCP protocols of an en-gNB, controlling the operation of one or more gNB-DUs. The gNB-CU terminates the F1 interface connected to the gNB-DU. The F1 interface is shown as reference numeral 198, which also denotes a link between a remote element of the RAN node 170 and a central element of the RAN node 170, e.g., between the gNB-CU 196 and the gNB-DU 195. The gNB-DU is a logical node that hosts the RLC, MAC, and PHY layers of a gNB or en-gNB, and its operation is partially controlled by the gNB-CU. One gNB-CU supports one or more cells. A cell is supported by only one gNB-DU. The gNB-DU terminates the F1 interface 198 connected to the gNB-CU. It should be noted that while the DU 195 is considered to include the transceiver 160, for example as part of an RU, some examples of this may have the transceiver 160 as part of a separate RU, for example under the control of the DU 195 and connected to the DU 195.RAN node 170 may also be an evolved NodeB (eNB) base station for Long Term Evolution (LTE), or any other suitable base station, access point, access node, or node.

[0019] The RAN node 170 includes one or more processors 152, one or more memories 155, one or more network interfaces (N / WI / F) 161, and one or more transceivers 160, interconnected via one or more buses 157. Each of the one or more transceivers 160 includes a receiver Rx 162 and a transmitter Tx 163. The one or more transceivers 160 are connected to one or more antennas 158. The one or more memories 155 include computer program code 153. The CU 196 may include the processor 152, memory 155, and network interface 161. Note that the DU 195 may also include its own memory / memories and processors and / or other hardware, which are not shown.

[0020] The RAN node 170 includes a module 150 including one or both of portions 150-1 and / or 150-2, which can be implemented in many ways. The module 150 may be implemented in hardware, for example, as module 150-1 implemented as part of one or more processors 152. The module 150-1 may also be implemented as an integrated circuit or through other hardware such as a programmable gate array. In other examples, the module 150 may be implemented as module 150-2 implemented as computer program code 153 and executed by one or more processors 152. For example, the one or more memories 155 and the computer program code 153 are configured by the one or more processors 152 to cause the RAN node 170 to perform one or more of the operations described herein. It should be noted that the functionality of the module 150 may be distributed, for example, distributed between the DU 195 and the CU 196, or implemented solely in the DU 195.

[0021] One or more network interfaces 161 communicate over a network, such as via links 176 and 131. Two or more gNBs 170 may communicate, for example, using link 176. Link 176 may be wired, wireless, or both, and may implement, for example, an Xn interface for 5G, an X2 interface for LTE, or other suitable interface for other standards.

[0022] The one or more buses 157 may be an address bus, a data bus, or a control bus and may include any interconnection mechanism, such as a series of lines on a motherboard or integrated circuit, optical fiber or other optical communication equipment, a radio channel, etc. For example, the one or more transceivers 160 may be implemented as a remote radio head (RRH) 195 for LTE or a distributed unit (DU) 195 for a gNB implementation for 5G, and other elements of the RAN node 170 may be in a physically different location from the RRH / DU, and the one or more buses 157 may be implemented in part as, for example, optical fiber cables or other appropriate network connections for connecting the other elements of the RAN node 170 (e.g., a central unit (CU), gNB-CU) to the RRH / DU 195. Reference numeral 198 also indicates those appropriate network links.

[0023] It should be noted that while the description herein refers to a "cell" performing a function, it should be clear that the equipment forming the cell performs the function. A cell constitutes part of a base station; that is, there can be multiple cells per base station. For example, there can be three cells for a single carrier frequency and associated bandwidth, with each cell covering one-third of a 360-degree area, so that the coverage area of ​​a single base station covers approximately an ellipse or circle. Furthermore, each cell can support a single carrier, and a base station may use multiple carriers. Thus, if there are three 120-degree cells per carrier and two carriers, the base station has a total of six cells.

[0024] The wireless network 100 may include one or more network elements 190, which may include core network functions and provide connectivity to additional networks, such as a telephone network and / or a data communication network (e.g., the Internet), via one or more links 181. Such core network functions for 5G may include an Access and Mobility Management Function (AMF), a User Plane Function (UPF), and / or a Session Management Function (SMF). Such core network functions for LTE may include an MME (Mobility Management Entity) / SGW (Serving Gateway) function. Note that these are merely example functions that may be supported by the network element 190, and both 5G and LTE functions may be supported. The RAN node 170 is coupled to the network element 190 via a link 131. The link 131 may be implemented, for example, as an NG interface for 5G, an S1 interface for LTE, or other appropriate interface for other standards. Network element 190 includes one or more processors 175, one or more memories 171, and one or more network interfaces (N / WI / F) 180 interconnected via one or more buses 185. The one or more memories 171 include computer program code 173. The one or more memories 171 and the computer program code 173 are configured by the one or more processors 175 to cause network element 190 to perform one or more operations.

[0025] The wireless network 100 may implement network virtualization, which is the process of aggregating hardware and software network resources and network functions into a single software-based management entity: a virtual network. Network virtualization includes platform virtualization and is often combined with resource virtualization. Network virtualization is classified as external virtualization, which aggregates multiple networks or portions of networks into a virtual unit, and internal virtualization, which provides network-like functionality to software containers on a single system. For example, a network may be deployed in a telecommunications cloud, with virtualized network functions (VNFs) running on data center servers, etc. For example, network core functions and / or radio access networks (e.g., Cloud RAN, O-RAN, edge cloud) may be virtualized. Note that the resulting virtualized entities of network virtualization are still implemented at some level using hardware, such as processor 152 or 175 and memory 155 and 171, and such virtualized entities also produce technical effects.

[0026] It will also be noted that the operations of the exemplary embodiments of the present disclosure may be performed by multiple cooperating devices (e.g., cRANs).

[0027] The computer-readable memories 125, 155, and 171 may be of any type suitable for the local technology environment and may be implemented using any suitable data storage technology, such as semiconductor-based memory devices, flash memory, magnetic memory devices and systems, optical memory devices and systems, fixed memory, and removable memory. The computer-readable memories 125, 155, and 171 may be means for performing storage functions. The processors 120, 152, and 175 may be of any type suitable for the local technology environment and may include, by way of non-limiting example, one or more of a general-purpose computer, a special-purpose computer, a microprocessor, a digital signal processor (DSP), and a processor based on a multi-core processor architecture. The processors 120, 152, and 175 may be means for performing functions such as control of the UE 110, the RAN node 170, and other functions described herein.

[0028] In general, various exemplary embodiments of user equipment 110 may include, but are not limited to, mobile phones such as smartphones, tablets, personal digital assistants (PDAs) with wireless communication capabilities, portable computers with wireless communication capabilities, image capture devices such as digital cameras with wireless communication capabilities, gaming devices with wireless communication capabilities, music storage and playback devices with wireless communication capabilities, internet appliances enabling wireless internet access and browsing, tablets with wireless communication capabilities, and portable units or terminals incorporating a combination of such functionality. Additionally, various embodiments of user equipment 110 may include, but are not limited to, devices integrated into vehicles, infrastructure associated with vehicular movement, wearable devices used by pedestrians or other non-vehicle users of the roadway, user equipment unrelated to transportation users, and user equipment configured to participate in sidelink scenarios, such as public safety user equipment and / or other commercial user equipment.

[0029] Having thus introduced one suitable, but non-limiting, technical context for the practice of exemplary embodiments of the present disclosure, the exemplary embodiments will now be described in more detail.

[0030] The features described herein generally relate to enhancing UE energy conservation in 5G NR. More specifically, the features described herein generally relate to UEs / devices with battery life targets of weeks or even years. For example, the features described herein may relate to devices without a continuous energy source, such as UEs that use a small, rechargeable or non-rechargeable, single coin-cell battery, such as those used for vertical use cases (e.g., including sensors and actuators widely deployed for monitoring, measurement, charging, etc.). Typically, these batteries are not rechargeable and are expected to last at least several years, as described in TR38.875. Furthermore, the features described herein may relate to wearables, such as smart watches, rings, e-health-related devices, industrial IoT devices, and / or medical monitoring devices, where typical battery capacities struggle to last up to one to two weeks as desired.

[0031] Some of the UE types named above (e.g., sensors, actuators, wearables, etc.) not only require long battery life, but also latency-critical services (e.g., sensors for fire detection and extinguishing). Therefore, solutions such as enhanced discontinuous reception (eDRX) (i.e., allowing the UE to extend the period at which it wakes up to monitor paging, thereby reducing average power consumption) may not be applicable, as eDRX introduces unacceptable communication latency.

[0032] Additionally or alternatively, exemplary embodiments of the present disclosure may be applicable to sidelink UEs, for example, in scenarios where a network or cell goes off / on for a UE configured to perform sidelink (SL) operations. NR SL methods may be implemented to provide communication between a vehicle and a network, infrastructure, other vehicles, or other road users in a surrounding / neighboring area. Such communication may enable proximity services (ProSe), i.e., the transmission of information about the surrounding environment between nearby devices, e.g., device-to-device (D2D) communication technologies. Such direct communication may be available even when network coverage is unavailable. Additionally or alternatively, NR SL methods may relate to the Internet of Things (IoT) and the automotive industry (e.g., reducing accident risk and a safer driving experience). These use cases may include vehicle-to-vehicle (V2V), vehicle-to-pedestrian (V2P), vehicle-to-infrastructure (V2I), and / or vehicle-to-network (V2N) message exchanges, which may be referred to as vehicle-to-everything (V2X). The allocation of V2V resources, i.e., time and frequency resources, in cellular can be controlled by the cellular network structure or performed autonomously by individual vehicles (e.g., their UE devices). The sidelink may use the same or a different carrier frequency or frequency band as the cellular communications.

[0033] To enable further UE power savings for device types such as those listed above, a new Rel. 18 study on low-power wake-up signaling (Working Item RP-213645) was recently adopted, which includes the following goals: "...Identify evaluation methods (including use cases) & KPIs [RAN1] Primarily targets low-power WUS / WUR for power-sensitive small form factor devices, including IoT use cases (e.g., industrial sensors, controllers) and wearables Other use cases are not excluded Consider and evaluate low-power wake-up receiver architectures [RAN1, RAN4] Consider and evaluate wake-up signal designs to support wake-up receivers [RAN1, RAN4] Consider and evaluate modifications to L1 procedures and higher layer protocols required to support wake-up signaling [RAN2, RAN1] Consider potential UE power savings compared to existing Rel-15 / 16 / 17 UE power saving mechanisms, as well as coverage availability and latency impacts. System impacts such as network power consumption, coexistence with non-low-power WUR UEs, and network coverage / capacity / resource overhead should also be considered [RAN1]. NOTE: The need for RAN2 evaluation is triggered as needed by RAN1..."

[0034] A technical effect of example embodiments of the present disclosure may be to address goals related to modifying L1 procedures and upper layer protocols to support wake-up signaling, for example, goals related to modifying procedures to support wake-up signaling (WUS).

[0035] The study [RP-213645] considers the use of a separate low-power wake-up receiver in the UE and evaluates how its use can reduce UE power consumption. The intention is that the UE's main radio can be in sleep mode (even powered off) to save power and can only be activated upon receiving a wake-up signal from the network. Essentially, the network can trigger the UE to wake up only when necessary in an event-driven manner by sending a special WUS to the UE that is monitored by a dedicated low-power WUS receiver in the UE. When the UE receives the WUS, the WUS receiver can trigger the wake-up of the normal NR transceiver and communication can begin. In this way, the ultra-low-power receiver (i.e., the WUS receiver) can wake up the main radio, which can otherwise be turned off or remain in (deep) sleep mode, as shown in Figure 2, which shows an example of UE operation using a low-power wake-up receiver (WUR). For example, the UE (210) may be off or in a sleep mode (e.g., RRC_IDLE, RRC_INACTIVE). A wake-up signal (240) may be received by the ultra-low power wake-up receiver (220). The ultra-low power wake-up receiver (220) may turn on the main radio (230) in response to the received wake-up signal (240). The UE (250) may be in an on mode (e.g., RRC_CONNECTED). A wake-up signal (280) may be received by the ultra-low power wake-up receiver (260). The ultra-low power wake-up receiver (260) may trigger the main radio (270) to remain on.

[0036] It is conceivable that a low-power wake-up receiver can be operated in a constantly "on" state with very low power consumption. By designing a simple (WUS) signal and using dedicated hardware that can only receive the WUS for monitoring, it is indeed expected that a WUS can consume significantly less power than an NR transceiver.

[0037] You will notice that there is a trade-off between power consumption and RF sensitivity (coverage) for WUS receivers, and that the sensitivity of WUS receivers is typically significantly worse than that of main (e.g., LTE / WIFI) receivers. For example, according to RWS-210168, for a main receiver in NR idle mode, RF sensitivity of -100 dBm is associated with an average power consumption of 30–50 mW. Typically, NR receivers can operate at approximately -100 dBm. In contrast, for a low-power WUS receiver (i.e., a near-zero-power receiver using passive circuits with an envelope detector), RF sensitivity is approximately -70 / 80 dBm and average power consumption is 7.4 nW. This represents a slight reduction in sensitivity, but a 100-fold power savings. A further example of the trade-off for a near-zero-power receiver (using a CMOS RF front-end with on-off keyed OOK energy detection) is shown in Figure 3. The power consumption row (320) shows the Moody ISSCC'18 power consumption of 7.4 nW at 310. The sensitivity row (340) shows that the Moody ISSCC'18 sensitivity is -76 dBm and -71 dBm at 330.

[0038] The cell size (coverage area) differs between low-power WUS and conventional DCI-based paging. Specifically, the WUS coverage area is typically smaller than the entire cell area where conventional DCI-based paging is supported. This is due to lower WUS receiver sensitivity and the use of different modulation / coding and possibly different carrier frequencies for WUS compared to conventional paging. A technical effect of example embodiments of the present disclosure may be to address this difference in UE receiver sensitivity and / or cell coverage area.

[0039] In conventional DCI-based paging, the DCI indicates the presence of a paging and the scheduling information of the paging. In other words, the DCI may indicate that the paging will be transmitted on the radio resource indicated in the scheduling information.

[0040] Referring now to Figure 4, an example is shown in which the wireless coverage area of ​​the WUS (420) is different (i.e., smaller) than the wireless coverage area of ​​the traditional paging (430). In the example of Figure 4, the wireless coverage area of ​​the traditional paging (430) encompasses at least the wireless coverage area of ​​the WUS (420) and an additional area. UEs (450) near the edge of the cell may be able to receive only the traditional paging (430), while UEs (440) near the center of the cell (410) may be able to receive both the WUS (420) and the traditional paging (430).

[0041] In this disclosure, the terms "coverage area" and "radio coverage area" may be used interchangeably to refer to an area where a UE can receive signals above a certain threshold / quality. The coverage area may have any shape and may be shorter / smaller in some directions than in other directions. This may be a function of transmitter characteristics, receiver characteristics, and / or environmental characteristics. For example, even if the UE is near a base station, it may be blocked by an obstacle and the UE may be out of the radio coverage area of ​​the WUS. In such a scenario, the UE may not be able to receive the WUS and may only be able to receive DCI-based paging.

[0042] It will be noted that the coverage area of ​​the WUS (420) can be the coverage area of ​​the WUS or the WUS beacon. The WUS is used to wake up one UE or a group of UEs so that they can monitor DCI-based paging. The WUS can be dedicated to that / those UEs, for example, in terms of dedicated resources in the time / frequency domain or by using a specific signal sequence / scrambling ID. The WUS beacon is used by any UE monitoring the dedicated WUS to determine whether the UE is still in radio coverage. Therefore, it can be a signal known to all UEs in terms of resources / sequence / scrambling, because the UE does not necessarily determine radio coverage based on the WUS, which is transmitted only when the UE needs to monitor DCI-based paging. If there are long periods without paging, the WUS may not be transmitted, and the UE may not know whether it is still in WUS coverage. However, constantly transmitting the WUS beacon can enable the UE to continuously monitor its WUS coverage status.

[0043] In a cell where both mechanisms (WUS and DCI-based paging) coexist, the UE may be able to determine if it is located in an area within the cell where it can receive WUS, in which case it may monitor WUS to save energy. If the UE cannot receive WUS, the UE may instead monitor regular paging for reachability at the expense of higher power consumption, because if the UE monitors WUS but cannot receive it, the paging will fail. In an example embodiment of the present disclosure, the UE may be able to determine whether to monitor WUS or regular paging based on network configuration.

[0044] In example embodiments of the present disclosure, a UE may be able to handle such coexistence of low-power WUS operation and non-WUS operation in a cell and appropriately determine when to monitor WUS and when not to monitor. Note that to avoid UE unreachability and unnecessary resource / energy costs for paging escalation on the network side, the network is assumed to always send both WUS and conventional paging, which is similar to WUS in NB-IoT.

[0045] RWS-210168 addressed the issue of ensuring UE reachability and noted that events such as keep-alive signals may be sent to the UE, which may trigger the UE's normal idle mode. Based on network / UE bidirectional confirmation, the UE may enter a near-zero power mode. In this mode, the UE may still be able to receive keep-alive signals such as WUS.

[0046] LTE eMTC and NB-IoT Release 15 defined WUS for paging monitoring in idle mode. LTE WUS can be a Zadoff-Chu sequence-based signal. Both WUS and PDCCH-based paging can be received by the same normal receiver. Such WUS can be transmitted constantly to avoid UE unreachability.

[0047] In 5G NR, Rel. 16 DCI-based WUS (DCP) during RRC connection is defined to control whether the UE should wake up to monitor the C-DRX on period (see, for example, TS38.331 and TS38.213).

[0048] In 5G NR, Rel-17 DCI-based WUS (Early Paging Notification, PEI) during RRC idle / inactivity is defined to control whether the UE should wake up to monitor for DCI-based paging (see, for example, TS38.331 and TS38.304).

[0049] In one exemplary embodiment, a UE that supports low-power wake-up signal monitoring may determine whether to monitor for WUS or DCI-based paging indications based on whether the UE is in WUS coverage (i.e., out of WUS coverage). In one exemplary embodiment, WUS coverage (or out of WUS coverage) may be determined based on network information (e.g., rules and / or parameters). In one exemplary embodiment, UE-specific monitoring operations may be performed for each of the cases where the UE is in WUS coverage and not in WUS coverage.

[0050] In a first exemplary embodiment, a UE supporting WUS may be configured via RRC signaling (e.g., RRC release / SIB) with a WUS configuration that includes network information for the UE to determine (non-)WUS coverage. In one exemplary embodiment, the network may be configured to define these rules / thresholds based on, for example, network conditions and the receiver sensitivity of a given UE.

[0051] In one exemplary embodiment, the network information for the UE to determine WUS coverage may include rules and / or parameters defining WUS coverage. The parameters may be set per cell and may include a WUS threshold and / or a WUS beacon threshold. Additionally or alternatively, the network information for the UE to determine WUS coverage may include rules and / or parameters defining non-WUS coverage. The parameters may be set per cell and may include an SSB-based RSRP and / or RSRQ threshold. Additionally or alternatively, the network information for the UE to determine WUS coverage may include radio conditions that may or may not allow the UE to use / monitor WUS. Such radio conditions may relate to at least one of NR (e.g., SSB), WUS, or WUS beacon signal power / quality, each of which may be monitored and / or measured by the UE. In one example, if the signal power / quality of NR or WUS or WUS beacon is sufficiently good (e.g., better than a threshold), the UE may monitor WUS. Additionally or alternatively, measurements of received power other than RSRP and corresponding thresholds may be used. In other words, the determination of whether the UE is in a WUS or non-WUS coverage area or whether the monitoring behavior should be changed may be based on measurements of received power of signals other than WUS, including but not limited to reference signals.

[0052] In one exemplary embodiment, the NW may UE-specifically configure NW information (e.g., parameters such as thresholds) based on the UE's location (in terms of channel conditions, radio signal strength) and / or UE-specific WUS receiver performance. The UE-specific WUS receiver performance may be obtained by the network based on a minimum Rx level defined in the UE capabilities. For example, the UE-specific parameter may be an offset to the minimum Rx level (e.g., x dB better than the minimum Rx level defined in the UE capabilities). It will be noted that 3GPP-defined test cases may ensure compliance with the minimum Rx level. Additionally or alternatively, the UE-specific WUS receiver performance may be based on UE assistance information regarding its WUS RF sensitivity, and the NW may use this assistance information to assist, for example, in defining RSRP / RSRQ thresholds for determining coverage areas and, therefore, the monitoring behavior the UE should adopt. The determination of WUS sensitivity may include a UE-based offset to apply to the RSRP threshold based on the supported WUS RF sensitivity level. Additionally or alternatively, the UE assistance information may include an indication of the UE's location within one or more coverage areas.

[0053] In one exemplary embodiment, the NW information may depend on the UE's last serving beam when in RRC_CONNECTED mode. In one exemplary embodiment, the NW information may exist per beam, and the UE may accordingly perform monitoring using the NW information associated with the beam that the UE used while in RRC_CONNECTED mode.

[0054] In a second exemplary embodiment, the UE may determine whether to monitor WUS or DCI-based paging based on the received WUS configuration, which may help determine whether the UE is in (non-)WUS coverage or parked.

[0055] Referring now to FIG. 5, an example of a UE monitoring operation based on whether the UE is in “WUS coverage” (520) or “non-WUS coverage” (530) is shown. The UE coverage may or may not be determined based on the distance between the UE and the base station or other network device (510), and / or network conditions, and / or UE WUR sensitivity. The UE may perform monitoring operation “A” when it is in “WUS coverage” (520), i.e., the UE may monitor the WUS and may sporadically monitor DCI-based paging indications. The UE may also detect whether it has moved out of “WUS coverage” (520) based on network information. The UE may perform monitoring operation “B” when it is in “non-WUS coverage” (530), i.e., the UE may monitor DCI-based paging indications and detect whether it has moved out of “non-WUS coverage” (530) based on network information. It will be appreciated that the example of Figure 5 is not limiting and the size of the coverage areas and / or their relationship to each other and / or to the network nodes may vary.

[0056] In one exemplary embodiment, if the UE is in "WUS coverage" (520) when it transitions to RRC_IDLE mode or RRC_INACTIVE mode, the UE may monitor only the WUS, or may monitor the WUS and paging DCI sparsely in time (i.e., less frequently than the normal paging cycle). The sparse monitoring of paging DCI may be performed according to a second paging cycle (e.g., defined / configured by the network), which may be a longer cycle (i.e., less frequent monitoring) than the conventional paging cycle. The UE may periodically check whether it has gone out of WUS coverage based on NW information (i.e., rules / parameters). This coverage check may be performed based on comparing the received WUS beacon with a threshold or based solely on the presence of a WUS beacon. When the UE detects that it has gone out of WUS coverage, it may switch on its main Rx and apply monitoring behavior when the UE is in "non-WUS coverage," which will be further described below. During sparse monitoring of the paging DCI, a coverage check may be performed based on SSB-based RSRP measurements and corresponding thresholds. The UE may consider the offset between the WUS beacon RSRP and the SSB-based RSRP (i.e., when both signals are received by the UE). For example, the UE may compare the most recent WUS beam received power / level with the current SSB-based RSRP (which may be received less frequently). The UE may revert to conventional paging based on failure to receive the WUS beacon, a WUS counter (e.g., after a certain number of (consecutive) failed WUS reception attempts), and / or satisfaction of the WUS beacon threshold and / or RSRP threshold.

[0057] In one exemplary embodiment, if the UE is in "non-WUS coverage" (530) when it transitions to RRC_IDLE mode or RRC_INACTIVE mode (i.e., sleep mode), the UE may only monitor normal paging DCI. The UE may periodically check whether it has left non-WUS coverage (entered WUS coverage) based on rules / parameters (e.g., meeting an RSRP / RSRQ threshold may trigger monitoring of a WUS beacon), and if it detects a WUS beacon, it may switch to operation when it is in "WUS coverage." The UE may monitor the WUS infrequently and return to WUS monitoring upon detecting a WUS. More rules may be defined (e.g., the WUS reception power / reception level may need to exceed a threshold, or WUS reception may be successful more than a certain number of times in a row). As an example, the UE may need to consider how often the UE is paged to determine whether to switch WUS monitoring operation. For example, if paged frequently, the UE may need to power on its main transceiver frequently, so there may not be much benefit in switching to WUS.

[0058] Referring now to Figure 6, a signaling flowchart between a UE (610) and a gNB (620) is shown. The UE (610) may perform monitoring operations according to exemplary embodiments of the present disclosure. It will be noted that paging from the network side (e.g., transmission of a WUS followed by a DCI-based paging) is not shown in Figure 6. In one exemplary embodiment, upon receiving the paging, the UE may respond to the paging in the same manner as in a conventional procedure.

[0059] At 622, the UE may be in an RRC_CONNECTED mode / state. At 624, the UE (610) may receive a system information block (SIB) and / or a radio resource control (RRC) release with a suspend configuration (optional) from the gNB (620). The RRC release message may be signaling dedicated to the delivery of network information. The SIB and / or RRC release may include a WUS configuration. For example, the WUS configuration may include network information such as rules / parameters related to WUS coverage. The WUS configuration may also include additional paging period information, such as a period for monitoring the WUS during each of monitoring operations "A" and "B" and a period for monitoring DCI-based paging. At 626, the UE may enter an RRC_INACTIVE mode, an RRC_IDLE mode, or a sleep mode.

[0060] In the first case, the UE (610) may be within WUS coverage and may perform monitoring operation "A" (630). At 632, the UE may monitor the WUS and may further monitor DCI-based paging indications according to additional paging period information (e.g., less frequently / longer periodicity than WUS monitoring). The monitoring may be performed using a low-power wake-up receiver / transceiver. The UE may monitor whether it remains within WUS coverage based on WUS coverage parameters / rules and / or WUS failure. At 634, 636, and 638, the UE (610) may detect a WUS beacon / WUS. Although FIG. 6 shows the detection of three WUS beacons / WUS, fewer or more WUS beacons / WUS may be detected by the UE (610). At 640, the UE may detect that it has moved out of WUS coverage based on the WUS configuration and may switch to monitoring operation "B." For example, the detected WUS at 638 may not meet a threshold, which may trigger a switch in monitoring operation. For example, the UE may determine that the power / level of the received WUS or WUS beacon is below a threshold. For example, the UE may determine that the quality of the received WUS or WUS beacon is below a threshold. For example, the UE may determine that the RSRP of the SSB is below a threshold. At 642, the UE (610) may detect the SSB after transitioning to monitoring operation "B".

[0061] At 644, regardless of the UE monitoring operation, if the UE (610) needs to be paged, the NW may trigger the transmission of a WUS and DCI-based paging indication to the UE (610). This may occur in case 1 (630) and / or case 2 (650).

[0062] In a second case, the UE (610) may not be within WUS coverage (e.g., may be out of WUS coverage) and may perform monitoring operation "B" (650). At 652, the UE may monitor DCI-based paging indications according to the paging period and may monitor the WUS infrequently (i.e., less frequently) (e.g., according to additional paging period information). Monitoring may be performed using the main receiver / transceiver. The UE may monitor whether it remains out of WUS coverage based on WUS coverage parameters / rules (e.g., SSB-based RSRP, or WUS receive power / level). At 654, 656, and 658, the UE may detect SSBs. Although FIG. 6 shows the detection of three SSBs, fewer or more SSBs may be detected by the UE (610). At 660, the UE may detect that it has entered WUS coverage based on the WUS configuration and may switch to monitoring operation "A." For example, the UE may determine that the power / level of the received WUS or WUS beacon meets or exceeds a threshold. For example, the UE may determine that the quality of the received WUS or WUS beacon meets or exceeds a threshold. For example, the UE may determine that the RSRP of the SSB meets or exceeds a threshold. At 662, the UE (610) may detect a WUS beacon / WUS after transitioning to monitoring operation "A".

[0063] Note that in Figure 6, each of Case 1 (630) and Case 2 (650) is optional, and the UE may experience these cases in a different order or may experience only one of these cases. The sequence shown in Figure 6 is not limiting.

[0064] A technical effect of the exemplary embodiments of the present disclosure may be to enable a network control mechanism for when a UE should perform WUS monitoring in a cell. A technical effect of the exemplary embodiments of the present disclosure may be to enable a trade-off between UE energy saving (which is increased when the UE monitors the WUS rather than DCI-based paging) and UE reachability (if the UE monitors the WUS when it cannot detect the WUS, the UE becomes unreachable, which leads to undesired paging escalation on the network side).
