Figure 6A DETAILED DESCRIPTION Figure 6B

[0022] ​In example embodiments of the invention, at least one new method and at least one apparatus for the new method are presented, in which in case of a common paging cause such as an emergency, the network can transmit an indication of paging arrival to all or a maximum number of user equipments in a single low power wake-up signal (LP-WUS) occasion.

[0023] Example embodiments of the invention relate to enhancements in 5G NR for UE energy saving, and in particular focus on UEs / devices with time targets for battery life of weeks or even years.

[0024] This includes devices without continuous energy source, e.g. UEs using small single coin cell rechargeable and non-rechargeable batteries such as those used for vertical use cases including sensors and actuators widely deployed for monitoring, measurement, charging, etc. Typically, their batteries are non-rechargeable and the battery is expected to last for at least several years. In addition, this also includes wearable devices such as smart watches, rings, electronic health related devices and medical monitoring devices for which it is challenging to maintain up to 1-2 weeks as needed with typical battery capacity.

[0025] Some of the UE types mentioned above (e.g. sensors, actuators and wearable devices) not only require long battery life but also require delay critical services such as sensors for fire detection and extinguishing as an example. Therefore, solutions such as eDRX (allowing extension of UE wake-up to monitor paging periodicity which in turn reduces average power consumption) are not applicable as eDRX would result in unacceptable communication delay.

[0026] In 3GPP 4G / LTE and 5G / NR wireless communication systems, a UE in idle (e.g. radio resource control (RRC) IDLE) or inactive (e.g. RRC_INACTIVE) state can be paged. If the UE receives a page, the UE can decide to transition to active state and wait for further communication from RAN or CN.

[0027] A UE in idle or inactive state can periodically wake up according to a paging cycle and monitor paging occasions (e.g. during one or more time and frequency resources) to determine whether it has been paged. In addition, the UE can monitor paging occasions associated with a paging subgroup that has been assigned to the UE. The paging cycle is measured according to radio frames.

[0028] Whenever a UE wakes up to monitor a paging occasion (PO), the UE consumes relatively more power than when it is sleeping, i.e., in a low power state. For a battery driven UE, greater power consumption reduces the UE’s remaining battery life. This sometimes provides a less than satisfactory user experience for the user. There is a desire for methods and apparatuses that can reduce the power consumed by a UE. In particular, the described systems, methods, and apparatuses enable a wireless communication device, e.g., a UE, to be assigned to a paging subgroup, which in some cases can allow the UE to wake up to monitor a paging occasion relatively less frequently, thereby reducing the UE’s power consumption.

[0029] One standardization project on low power wake-up signals has been approved at the time of this application to enable further UE power saving for devices such as the device types described above, and includes the following listed objectives. The present invention relates to the highlighted objectives, which aim to study and evaluate the procedure changes needed to support WUS.

[0030] The study project includes the following objectives: Identify evaluation methodology (including use cases) and KPIs [RAN1]: Primarily for power sensitive low power WUS / WUR, miniaturized devices including IoT use cases such as industrial sensors, controllers, and wearable devices, Other use cases are not precluded; Study and evaluate low power wake-up receiver architecture [RAN1, RAN4]; Study and evaluate wake-up signal design to support wake-up receiver [RAN1, RAN4]; L1 procedures and higher layer protocol changes needed to support wake-up signal [RAN2, RAN1]; Study potential UE power saving gains compared to existing standard UE power saving mechanisms and their coverage availability as well as latency impact. System impacts such as network power consumption, coexistence with non-low power WUR UEs, network coverage / capacity / resource overhead should be included in the study project.

[0031] Note: The need for RAN2 evaluation will be triggered by RAN1 if necessary.

[0032] The study will consider the use of a separate low power wake-up receiver at the UE and evaluate how power consumption at the UE can be reduced. The intention is that the main radio of the UE can be in sleep mode (or even switched off) for power saving and only activated when a wake-up signal is received from the network.

[0033] It is assumed that the low power wake-up receiver can operate with very low power consumption in always-on or duty cycle fashion. In fact, by designing a simple (WUS) signal and using dedicated hardware for its monitoring (which is only able to receive WUS), it is expected to consume significantly less power compared to the NR transceiver.

[0034] Figure 1 UE operation with low power wake-up receiver (WUR) is shown. As Figure 1 shown, on the left side is the wake-up signal (off) signal to the ultra-low power wake-up receiver, then the signal is sent to the off or deep sleep main radio. As Figure 1 shown, on the right side is the wake-up signal (on) signal to the ultra-low power wake-up receiver, then the trigger is sent to the on main radio.

[0035] Under the operation of the LP-WUS mode: in the idle / active state, the UE is expected to wake up occasionally to detect / decode the indication of paging arrival, i.e., LP-WUS. In order to increase power saving and optimize the LP-WUS resource, the NW will categorize the UEs in different groups, and the UE will be configured to monitor only certain LP-WUS occasions to detect / decode the associated LP-WUS. Therefore, the NW will only send the LP-WUS in certain LP-WUS occasions (associated with this particular UE group) to the UE as an indication of paging arrival, and the UE is expected to only monitor those specific occasions as an indication of paging arrival.

[0036] Considering the above LP-WUS paging mechanism, if the NW wants to page all UEs for any common purpose (such as emergency reasons), the NW must transmit the LP-WUS on at least one occasion of each group as an indication of paging arrival with common reasons (such as emergency).

[0037] As Figure 2 shown, the NW has categorized the UEs into 4 LP-WUS groups, group 1, group 2, group 3 and group 4. At time t1, the NW wants to schedule the LP-WUS as an indication of paging arrival for (common reason) emergency. In the traditional way, the NW must schedule the LP-WUS as an indication of paging arrival, i.e., the NW must schedule the LP-WUS on at least one occasion of each LP-WUS group.

[0038] As Figure 2 shown in step 210 of FIG. 2, there is a paging arrival for a common reason (for example, but not limited to, an emergency common reason) at T1. As Figure 2As shown in step 220, the network (NW) schedules LP-WUS across all groups (e.g., group-1, group-2, and group-3) as an indication of paging arrival for common causes (such as, but not limited to, urgent common causes). Figure 2 As shown in step 230, for different groups of UEs, the LP-WUS paging timing is received up to T2. Then, as... Figure 2 As shown in step 240, note that the delay involved in sending LP-WUS for public causes (such as emergency public causes) to all UEs is T2-T1.

[0039] One objective of the proposed invention is to enable the network (NW) to send a paging arrival indication to all or a maximum number of UEs in a single LP-WUS moment in the event of a public paging reason (such as, but not limited to, an emergency).

It is noted that the virtualized entities resulting from network virtualization are still implemented to some extent using hardware such as the processors DP 10, DP 12A, DP 13A, and / or DP 14A and the memories MEM 10B, MEM 12B, MEM 13B, and / or MEM 14B, and such virtualized entities also create technical effects.

[0052] ​The computer readable memories MEM 12B, MEM 13B and MEM 14B can be of any type suitable to the local technical environment, and can 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 MEM 12B, MEM 13B and MEM 14B can be means for performing storage functions. By way of non-limiting example, the processors DP 10, DP 12A, DP 13A and DP 14A can be of any type suitable to the local technical environment, and can include one or more of general purpose computers, special purpose computers, microprocessors, digital signal processors (DSPs) and processors based on multi-core processor architectures, as examples. The processors DP 10, DP 12A, DP 13A and DP 14A can be means for performing functions, such as controlling the UE 10, the NN 12, the NN 13, and other functions described herein.

[0053] In general, the various embodiments of any of these devices can include, but are not limited to, cellular telephones such as smart phones, tablets, personal digital assistants (PDAs) having wireless communication capabilities, portable computers having wireless communication capabilities, image capture devices such as digital cameras having wireless communication capabilities, gaming devices having wireless communication capabilities, music storage and playback appliances having wireless communication capabilities, Internet appliances permitting wireless Internet access and browsing, tablets with wireless communication capabilities, as well as portable units or terminals that incorporate combinations of such functions.

[0054] In addition, the various embodiments of any of these devices can be used in a UE vehicle, a high altitude platform station, or any other such type node associated with a terrestrial network, or any drone type radio, or radios in aerial vehicles or other airborne vehicles, or in waterborne vessels such as ships.

[0055] As mentioned above, one object of the proposed invention is to enable the NW to send an indication of paging arrival to all or a maximum number of UEs in a single LP-WUS occasion in case of a common paging cause, like an emergency.

[0056] Transmission of low power reference signals (so called LP-Beacons) is being discussed to keep the LR synchronized with the NW. These LP-reference signals / LP-Beacons are common for all UEs. Hence, all UEs are expected to detect / decode these LP-reference signals. Hence, this LP-reference signal is an opportunity for the NW to address all UEs once for a common cause (like emergency). Hence, the proposed solution by the invention is to use the LP-reference signals / LP-Beacons to schedule the LP-WUS for a common cause like emergency. As an alternative solution, a dedicated LP-WUS can be sent on the location of the LP-Beacon with the content of the emergency information.

[0057] Figure 5 It is clearly depicted that one of the LP-Beacons (first occasion) has been constructed with an indication of a paging arrival with an emergency cause. Since all UEs are expected to detect / decode the LP-reference / LP-Beacons, the LP-WUS can be conveyed to all UEs at one occasion of the LP-Beacons. The NW can (optionally) repeat the indication of the paging arrival on other LP-SS / LP-Beacons and also schedule the LP-SS / LP-Beacons on all occasions of all groups.

[0058] There can be an occasion where any one (or more) LP-WUS group paging occurs earlier than the LP-WUS-SS / Beacon, the NW can still choose to send an indication for the paging arrival on these occurrences. It will give the indication to the UEs belonging to that group faster. The NW can also send the indication for the paging arrival on the nearest LP-SS / Beacon to reach all / maximum number of UEs earliest.

[0059] As shown in step 310 of Figure 3 There is an LP-Beacon carrying an indication of a paging arrival for a common cause such as but not limited to an emergency common cause. As shown in step 320 of Figure 3 There is a paging arrival for a common cause such as but not limited to an emergency common cause at T1. As shown in step 330 of Figure 3 Note the reduced latency involved in sending the LP-WUS for a common cause such as an emergency common cause to all UEs. As shown in step 340 of Figure 3 There are LP-WUS paging occasions for different groups of UEs. Then, as shown in step 350 of Figure 3 The network (NW) schedules the LP-WUS across all group occasions as an indication of a paging arrival for a common cause such as but not limited to an emergency common cause.

[0060] Figure 3 It is clearly shown that the latency involved in addressing the LP-WUS as an indication of a paging arrival to all UEs has been significantly reduced.

[0061] The proposed idea provides an easily detectable LP-reference signal (LP-SS / P Beacon / LP-reference signal) which can be used as an indication of a paging arrival in the LP-WUS operation mode in RRC idle / inactive state.

[0062] Figure 3 It is clear that the proposed idea "LP-reference signal (beacon) for indicating a paging arrival for a common purpose (like emergency) to all UEs" can improve the overall latency to address all UEs in a single instant.

[0063] Figure 3 A possible structure of the LP-reference signal / beacon with optional fields for a common purpose (like emergency) is depicted.

[0064] As Figure 4 shown, there is an optional field in the LP-SS / Beacon which can contain a unique PN sequence which is an indication of a paging arrival for a common purpose (like emergency).

[0065] M-sequence or Walsh code will be adapted with OOK and FSK (different FSK) modulation and its construction is simple and has high detection reliability which can be applicable for emergency paging indication sequence.

[0066] Binary sequence with high Hamming distance will enable the LR to detect the expected sequence even with few errors (non-perfect correlation can also serve this purpose).

[0067] Keeping a common unique sequence across NW or cell specific for a common purpose (like "emergency") is implementation dependent on the NW.

[0068] Alternatively, the NW can configure a dedicated time and frequency location for the device to monitor for this specific emergency LP-SS / Beacon signal.

[0069] The NW can inform the device about the unique sequence for a common purpose via SIB or dedicated signaling.

[0070] Alternatively, the LP-SS / Beacon for a common purpose (like emergency indication) can be a dedicated LP-WUS with only emergency indication.
