Description

[0001] A WIRELESS DEVICE, FIRST NETWORK NODE, AND METHODS PERFORMED THEREBY, FOR HANDLING REPORTING

[0002] TECHNICAL FIELD

[0003] The present disclosure relates generally to a wireless device and methods performed thereby for handling reporting. The present disclosure also generally relates to a network node and methods performed thereby for handling reporting.

[0004] BACKGROUND

[0005] Wireless devices within a wireless communications network may be e.g., User Equipments (UEs), stations (STAs), mobile terminals, wireless terminals, terminals, and / or Mobile Stations (MS). Wireless devices are enabled to communicate wirelessly in a cellular communications network or wireless communication network, sometimes also referred to as a cellular radio system, cellular system, or cellular network. The communication may be performed e.g., between two wireless devices, between a wireless device and a regular telephone and / or between a wireless device and a server via a Radio Access Network (RAN) and possibly one or more core networks, comprised within the wireless communications network. Wireless devices may further be referred to as mobile telephones, cellular telephones, laptops, or tablets with wireless capability, just to mention some further examples. The wireless devices in the present context may be, for example, portable, pocket-storable, hand-held, computer-comprised, or vehicle-mounted mobile devices, enabled to communicate voice and / or data, via the RAN, with another entity, such as another terminal or a server.

[0006] The wireless communications network covers a geographical area which may be divided into cell areas, each cell area being served by a network node, which may be an access node such as a radio network node, radio node or a base station, e.g., a Radio Base Station (RBS), which sometimes may be referred to as e.g., gNB, evolved Node B (“eNB”), “eNodeB”, “NodeB”, “B node”, Transmission Point (TP), or BTS (Base Transceiver Station), depending on the technology and terminology used. The base stations may be of different classes such as e.g., Wide Area Base Stations, Medium Range Base Stations, Local Area Base Stations, Home Base Stations, pico base stations, etc... , based on transmission power and thereby also cell size. A cell is the geographical area where radio coverage is provided by the base station or radio node at a base station site, or radio node site, respectively. One base station, situated on the base station site, may serve one or several cells. Further, each base station may support one or several communication technologies. The base stations communicate over the air interface operating on radio frequencies with the terminals within range of the base stations. The wireless communications network may also be a non-cellular system, comprising network nodes which may serve receiving nodes, such as wireless devices, with serving beams. In 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE), base stations, which may be referred to as eNodeBs or even eNBs, may be directly connected to one or more core networks. In the context of this disclosure, the expression Downlink (DL) may be used for the transmission path from the base station to the wireless device. The expression Uplink (UL) may be used for the transmission path in the opposite direction i.e., from the wireless device to the base station.

[0007] The standardization organization 3GPP is currently in the process of specifying a New Radio Interface called NR or 5G-UTRA, as well as a Fifth Generation (5G) Packet Core Network (CN), which may be referred to as Next Generation (NG) Core Network, abbreviated as NG-CN, NGC, 5G CN or 5G Core (5GC). NG may be understood to refer to the interface / reference point between the Radio Access Network (RAN) and the CN in 5G / NR. In a 5G System (5GS), a radio base station in NR may be referred to as a gNB or 5G Node B. An NR UE may be referred to as an nUE.

[0008] Internet of Things (loT)

[0009] The Internet of Things (loT) may be understood as an internetworking of communication devices, e.g., physical devices, vehicles, which may also be referred to as "connected devices" and "smart devices", buildings and other items — embedded with electronics, software, sensors, actuators, and network connectivity that may enable these objects to collect and exchange data. The loT may allow objects to be sensed and / or controlled remotely across an existing network infrastructure.

[0010] "Things," in the loT sense, may refer to a wide variety of devices such as heart monitoring implants, biochip transponders on farm animals, electric clams in coastal waters, automobiles with built-in sensors, DNA analysis devices for environmental / food / pathogen monitoring, or field operation devices that may assist firefighters in search and rescue operations, home automation devices such as the control and automation of lighting, heating, e.g. a “smart” thermostat, ventilation, air conditioning, and appliances such as washer, dryers, ovens, refrigerators or freezers that may use telecommunications for remote monitoring. These devices may collect data with the help of various existing technologies and then autonomously flow the data between other devices.

[0011] It is expected that in a near future, the population of loT devices will be very large. Various predictions exist, among which one assumes that there will be >60000 devices per square kilometer, and another assumes that there will be 1000000 devices per square kilometer. A large fraction of these devices are expected to be stationary, e.g., gas and electricity meters, vending machines, etc.

[0012] Machine Type Communication (MTC)

[0013] Machine Type Communication (MTC) has in recent years, especially in the context of the Internet of Things (loT), shown to be a growing segment for cellular technologies. An MTC device may be a communication device, typically a wireless communication device or simply user equipment, that is a self and / or automatically controlled unattended machine and that is typically not associated with an active human user in order to generate data traffic. An MTC device may be typically simpler, and typically associated with a more specific application or purpose, than, and in contrast to, a conventional mobile phone or smart phone. MTC involves communication in a wireless communication network to and / or from MTC devices, which communication typically may be of quite different nature and with other requirements than communication associated with e.g. conventional mobile phones and smart phones. In the context of and growth of the loT, it is evident that MTC traffic will be increasing and thus needs to be increasingly supported in wireless communication systems.

[0014] Wake-up receiver (WUR), sometimes also referred to as ‘wake-up radio’, may be understood to relate to enabling a low power receiver in UEs, which, in case of the detection of a ‘Wake-up signal’ (WUS), may wake up the main, e.g., baseband / higher power, receiver to detect an incoming message, typically paging, e.g., the Physical Downlink Control Channel (PDCCH) in paging occasions (PCs), scheduling the paging message on the Physical Downlink Shared Channel (PDSCH). The main benefit of employing WUR may be understood to be lowering energy consumption and longer device battery life, or at a fixed energy consumption, the downlink latency may be reduced, there may be shorter Discontinued Reception (DRX) / duty-cycles, and more frequent checks for incoming transmissions.

[0015] Figure 1 is a schematic diagram illustrating location of a WUS and the paging occasion (PO) to which it is associated. In Figure 1 , white blocks indicate possible WUS, and PO positions, whereas the black boxes indicate actual WUS and PO positions.

[0016] WUS for NB-loT and LTE-M

[0017] Release 15

[0018] In Rel-15, WUS was specified for NarrowBand loT (NB-loT) and Long Term Evolution for Machines (LTE-M). The main motivation was UE energy consumption reduction since, with the coverage enhancement, PDCCH may be repeated many times and the WUS may be relatively much shorter and hence may require less reception time for the UE. The logic may be understood to be that a UE may check for a WUS a certain time before its PO, and only if a WUS is detected, the UE may continue to check for PDCCH in the PO, and if not, which is most of the time, the UE may go back to a sleep state to conserve energy. Due to the coverage enhancements, the WUS may be of variable length depending on the coverage of the UE, see Figure 2.

[0019] Figure 2 is a schematic diagram illustrating WUS for NB-loT and LTE-M. As depicted in Figure 2, where the horizontal axis represents time, the WUS may have a duration, which may be a fraction of a configured maximum WUS duration. Between the end of the configured maximum WUS duration and the beginning of the associated paging occasion (PO) there may be a gap. A gap may be understood as a time offset between the WUS monitoring occasion and the paging occasion. A gap may also be referred to as an offset.

[0020] A WUS may be based on the transmission of a short signal that may indicate to the UE that it may need to continue to decode the Downlink (DL) control channel e.g., the full Narrowband PDCCH (NPDCCH) for NB-loT. If such signal is absent, e.g., in Discontinuous Transmission (DTX) that is, if the UE does not detect it, then the UE may go back to sleep without decoding the DL control channel. The decoding time for a WUS may be considerably shorter than that of the full NPDCCH since it may only need to contain one bit of information, whereas the NPDCCH may contain up to 35 bits of information. This, in turn, may be understood to reduce UE power consumption and lead to longer UE battery life. The WUS would be transmitted only when there may be paging for the UE. But if there is no paging for the UE, then the WUS may be understood to not be transmitted, implying a discontinuous transmission (DTX) and the UE may go back to deep sleep e.g., upon detecting DTX instead of WUS. This is illustrated in Figure 1 , where white blocks indicate possible WUS, and PO positions whereas the black boxes indicate actual WUS and PO positions.

[0021] The specification of Rel-15 WUS is spread out over several parts of the LTE 36-series standard, e.g., 36.211 , 36.213, 36.304 and 36.331.

[0022] A UE may report its WUS capability to the network, and WUS gap capability, that is, the minimum time required for the UE to start up its main receiver, see below. Further WUS information was added in the specification to the paging message / request from Mobility Management Entity (MME) to an eNB, see UE radio paging capabilities. An eNB may use WUS for paging the UE if and only if (IFF) 1) WUS is enabled in the cell, e.g., WUS-Config may be present in System Information (SI), and 2) the UE may support WUS according to the wakeUpSignal-r15 UE capability, see also the description of WUS gap below.

[0023] WUS was introduced for both LTE-M and NB-loT with support for both DRX and extended DRX (eDRX), the former with a 1 -to-1 mapping between the WUS and the PO, and for the latter in an addition with the possible configuration of 1-to-N, many, POs. An eNB may configure one WUS gap for UEs using DRX, and another one for UEs using eDRX, see e.g., TS 36.331 , version 16.6.0, examples are given for NB-loT, LTE-M is similar:

[0024] The UE capabilities may also indicate the minimum WUS gaps required for the UE to be able to decode PDCCH in the associated PO, for DRX and eDRX, respectively, see TS 36.331 , version 16.6.0:

[0025] UE-RadioPaginglnfo-NB information element wakeUpSignalMinGap-eDRX wakeUpSignalMinGap-eDRX may be understood to indicate the minimum gap the UE may support between WUS or Group WUS (GWUS) and associated PO in case of eDRX in Frequency Division Duplexing (FDD), as specified in TS 36.304, version 16.5.0. Value ms40 corresponds to 40 ms, value ms240 corresponds to 240 ms and so on. If this field is included, the UE may be required to also indicate support for WUS or GWUS for paging in DRX.

[0026] At the end of Rel-15, a longer WUS gap of 1s or 2s was introduced to enable the use of a Wake-Up receiver (WUR), since, starting up the main baseband receiver if a WUR is used for the detection of WUS may take longer time. If this is supported in the cell, an eNB may include timeOffset-eDRX-Long in the WUS-Config in SI, see above. In TS 36.304, version 16.5.0, the UE behavior for monitoring paging with WUS is specified, and in Table 7.4-1 it is indicated which WUS time gap the UE and the eNB may be required to apply depending on the reported UE capability.

[0027] Paging with Wake Up Signal

[0028] Section 7.4 of TS 36.304, version 16.5.0 describes a specification of paging with wake up signal. According to this specification, paging with Wake Up Signal may only be used in the cell in which the UE most recently entered RRCJDLE triggered by: a) reception of RRCEarlyDataComplete, or b) reception of RRCConnectionRelease not including noLastCell Update, or c) reception of RRCConnectionRelease including noLastCell Update and the UE was using (G)WUS in this cell prior to this Radio Resource Control (RRC) connection attempt.

[0029] If the UE is in RRCJDLE, the UE may not be using GWUS according to clause 7.5 and the UE supports WUS, and WUS configuration may be provided in system information, the UE may be required to monitor WUS using the WUS parameters provided in System Information. When DRX is used and the UE detects WUS, the UE may be required to monitor the following PO. When extended DRX is used and the UE detects WUS, the UE may be required to monitor the following numPOs POs or until a paging message including the UE's Non-Access Stratum (NAS) identity may be received, whichever may be earlier. If the UE does not detect WUS, the UE may not be required to monitor the following PO(s). If the UE missed a WUS occasion, e.g., due to cell reselection, it may monitor every PO until the start of the next WUS or until the paging time window (PTW) ends, whichever may be earlier. A PTW may be understood as a time window containing one or more paging occasions (POs) which may be required to be monitored by the UE in eDRX operation. numPOs = Number of consecutive Paging Occasions (PO) mapped to one WUS provided in system information where (numPOs^V).

[0030] The WUS configuration, provided in system information, may include a time-offset between the end of WUS and the start of the first PO of the numPOs POs the UE may be required to monitor. The timeoffset in subframes, used to calculate the start of a subframe gO, see TS 36.213, version 16.7.1 , may be defined as follows. For a UE using DRX, it may be the signalled timeoffsetDRX. For a UE using eDRX, it may be the signalled timeoffset-eDRX-Short if timeoffset-eDRX-Long is not broadcasted. And for a UE using eDRX, it may be the value determined according to Table 7.4-1 if timeoffset-eDRX-Long is broadcasted. Table 7.4-1 : Determination of GAP between end of WUS and associated PO

[0031] The timeoffset may be used to determine the actual subframe gO as follows, taking into consideration resultant System Frame number (SFN) and / or Hyper Frame SFN (H-SFN) wraparound of this computation: gO = PO - timeoffset, where PO is the Paging Occasion subframe as defined in clause 7.1.

[0032] For a UE using eDRX, the same timeoffset may apply between the end of WUS and associated first PO of the numPOs POs for all the WUS occurrences for a PTW.

[0033] The timeoffset, gO, may be used to calculate the start of the WUS as defined in TS 36.213, version 16.7.1.

[0034] In essence, the UE may only use WUR, or timeOffset-eDRX-Long, if it may be capable of starting up the main receiver as quickly as indicated by the value used in SI. If not, it may fall back to using timeOffset-eDRX-Short, without WUR.

[0035] Since UEs may share PO, the eNB may, in the worst case, have to transmit up to 3 WUSs for one PO, for example, corresponding to timeoffsetDRX, timeoffset-eDRX-Short, and timeoffset-eDRX-Long.

[0036] Figure 3 is a schematic diagram illustrating the use of eDRX and DRX WUS gaps for NB- loT and LTE-M. In the non-limiting example depicted in Figure 3, a first WUS is transmitted having a timeoffset-eDRX-Long between its transmission and that of the PDCCH in the PO. A second WUS is transmitted having a shorter, timeoffsetDRX, between the transmission of the second WUS and that of the PDCCH in the PO. After the PDCCH, the PDSCH may be transmitted.

[0037] WUS UE grouping objective in Rel-16

[0038] In the Rel-16 WID, it was agreed that WUS should be further developed to also include UE grouping, such that the number of UEs that may be triggered by a WUS may be further narrowed down to a smaller subset of the UEs that may be associated with a specific paging occasion (PO). The objective was to specify the following set of improvements for machinetype communications for Bandwidth reduced Low complexity / Coverage Enhancement (BL / CE) UEs: Improved DL transmission efficiency and / or UE power consumption. Particularly, to specify support for UE-group wake-up signal (WUS) [RAN1, RAN2, RAN4],

[0039] The purpose may be understood to be to reduce the false paging rate, that is, to avoid that that a given UE may be unnecessarily woken up by a WUS transmission intended for another UE. This feature may be referred to as Rel-16 group WUS, or GWUS. However, this is not directly related to WUR and will not further be explained here.

[0040] Rel-17 NR PEI

[0041] In Rel-17, discussions started on introducing a WUS for NR, then called ‘Paging Early Indication’ (PEI). However, since at the time no coverage enhancement was specified for NR, the only gain for Rel-17 PEI was for scenarios where the small fraction of UEs are in bad coverage and with large synchronization error due to the use of longer DRX cycles. The gain for such UEs was that, with the use of PEI, they would typically only have to acquire one Synchronisation Signal Block (SSB) before decoding PEI, instead of up to 3 SSBs if PEI was not used, value according to UE vendors. Accordingly, for most UEs, Rel-17 PEI may not result in gains or increased performance.

[0042] Rel-17 PEI may also support UE grouping for false paging reduction, similar to the Rel-16 GWUS above, which may have some gains at higher paging load.

[0043] In RAN#93e it was agreed that PEI may be PDCCH-based, as seen in from the next subsection, making it much less interesting for WUR, since the main baseband receiver may be understood to be required for decoding PEI. That is, the main baseband received may be understood to not be able to be in sleep state, and therefore there may be no WUR gains.

[0044] IEEE WUR

[0045] In IEEE, the support for WUR has been specified to a greater extent than in 3GPP. That is, the focus was on low power WUR from the start, and the design may use WUR not only for receiving the WUS but also other control signals and signaling, such as synchronization and mobility information. This may be understood to allow the stations, corresponding to UEs in 3GPP, to only use the WUR when there may be no user-plane data transmission ongoing.

[0046] Similar to the 3GPP solution, the use of WUR may only be enabled in stations and not in access points (APs), that is, for downlink communication only. The AP may advertise that it has WUR operation capability, along with WUR configuration parameters, among other info, in which band / channel WUR may be operational, which may be different from the band / channel used for data transmission using the main receiver, e.g., WUR in 2.4 GHz band but data communication in 5 GHz band. Also, it may be noted that the WUR operating channel may be advertised in the legacy beacon, and that the WUR discovery operating channel may be different from the WUR operating channel. Stations may then request to be configured with WUR mode of operation. This request may have to be granted by the AP, and in case it is granted, the station may be further configured / setup for WUR mode of operation, that is, the configuration may be only valid for the connection to the associated AP, and further, the configuration may have to be torn down / de-configured if WUR is not to be used anymore. Both continuous WUR, that is, the receiver open all the time, and duty-cycled WUR, that is, receiver only open during preconfigured time slots, mode of operations may be supported. For the latter, the length of the duty-cycles and on-time during wake up may be part of the WUR configuration.

[0047] Unlike the 3GPP solution, the WUR operation mode may be understood to be a “substate” of the regular operation and upon the detection of a WUS transmission from the AP, the station may resume the power saving mechanism it may have been configured with before entering the WUR operation mode. That is, IEEE has specified a number of different power saving mechanisms, and for example if duty-cycled monitoring of the downlink has been configured for the station, it may switch to that upon detection of the WUS, unlike the specified 3GPP mechanism which may only cover paging, and the UE may continue to monitor PDCCH if WUS is detected.

[0048] A station receiving the IEEE WUS may be required to synchronize to the wireless medium prior to performing any transmissions, that is, using sync info in the beacon from the AP, typically transmitted every 100ms, or from the transmission to another station. Synchronization to the wireless medium may be understood to refer to the following in IEEE 802.11; a station changing from sleep to awake in order to transmit may have to perform channel clear assessment until it may receive one or more frames that may allow it to correctly set the virtual carrier sensing. This may be understood to be to prevent collisions with transmissions from hidden nodes. In short, the virtual carrier sensing may tell a station to defer for a time period even if the wireless medium may appear to be idle, and may be set by receiving frames that may indicate the duration of an ongoing frame exchange. It may be noted that in WiFi technology and typically, one beacon transmission may be enough to sync for the station, that is, no need to acquire several transmissions due to poor coverage. Unlike operation in licensed bands, the station may also have to apply carrier sensing, and also possibly re-acquire channel sensing parameters, before uplink transmission.

[0049] The physical wake-up signal (WUS) in IEEE may contain complete frames which may have to be processed by the station. The drawback with this design may be understood to be that it may require more processing and handling and processing in the station, that is, compared to a simple WUR design, which may trigger one pre-defined activity in case WUS may be detected. The benefit may be that it may contain more information and the solution may be more general. The IEEE WUS may contain information to indicate if the WUS may be a WUR sync beacon, see below, a WUR discovery beacon, see below, or a regular WUS, intended to wake the station up. The WUS may also contain proprietary frames, which may e.g., be used to directly turn actuators on / off. The transmission may use on / off keying (OOK) modulation, using Manchester coding, but may be using multi-carrier OOK which may be generated by an Orthogonal Frequency Division Multiplexing (OFDM) transmitter, that is, WUR may be enabled as a software upgrade in APs. The WUS may be 4 MHz wide, but a whole 20 MHz channel may be reserved. The WUS may start with a 20 MHz legacy preamble, to allow other stations to perform carrier sense, followed by 4 MHz Manchester coded OOK. Two data rates may be supported: 62.5 kilobits per second (kbps) and 250 kbps, and link adaptation may be up to the AP, each packet may be self-contained and include the data rate, that is, in the WUR there may be two possible sync words used to signal the data rate.

[0050] The WUS may contain the following information: a) Station Identifier (ID), or group ID, grouping of stations may be supported, b) payload up to 22 bytes, c) short frames may contain only basic information; which WUS frame type + addressing, d) ordinary frames may contain control information, and in addition proprietary information, e) WUR beacons may contain Basic Service Set Identifier (BSS-ID), sync information, time counter, f) similar structure for WUS and WUR beacons, sync words may indicate the data rate, the station may then detect the header, from this, the station may tell if it is WUS or beacon, then check body, and g) WUR discovery frames may contain mobility related information to allow for lower power scan, see below.

[0051] Regarding mobility, both WUR sync beacons and WUR discovery beacons have been specified, which may only require the WUR to be used for reception, such that stations may stay in the WUR operation mode unless there is data transmission for the station. That is, stations may only need to switch back to legacy Power Saving Mode (PSM) upon WUS detection, or when moving to a new AP. WUR sync beacons may be used by stations to obtain rough synchronization, for data transmission the legacy beacon may be required to still be acquired, and WUR discovery beacons may be used to carry (legacy) mobility information to enable quick / low energy scanning, allowing stations, only using the WUR, to get information related to local and roaming scans for nearby APs, e.g., Service Set Identity (SSID) and main radio operating channels, if the channel quality should deteriorate.

[0052] That is, in the WUR discovery beacon, the AP may indicate one or more Basic Service Set (BSS), and the BSS-ID may have a one-to-one mapping with the assigned SSID name, in which WUR may be supported such that stations may not have to scan all frequencies / channels. Since the WUR discovery beacon may contain the legacy mobility information, there may be some duplication / redundancy in the broadcasted information. This may allow for low power scanning, using only the WUR. Note however that mobility in IEEE may be restricted to the same AP, and that hand-over between APs etc. may not be supported in the same way as in 3GPP. If a station in WUR operation mode moves to a new AP, it may have to move out of WUR operation mode and use the main receiver to obtain the beacon, sync, configuration, and associate to the new AP.

[0053] NR WUR

[0054] In Rel-18, WUR has been studied for NR. The output of the Rel-18 study item on “low-power wake-up signal and receiver for NR” is collected in technical report TR 38.869, “Study on low- power Wake-up Signal and Receiver for NR”. According to the outcome of this study, one important aspect of designing WUR / WUS may be understood to be synchronization, called Low- Power Synchronization Signal (LP-SS) as highlighted below 3:

[0055] RAN1 studied synchronization of Low-Power Wake-Up Radio (LP-WUR). At least for LP- WUR that may not be able to receive existing Primary Synchronization Signal (PSS) / Secondary Synchronization Signal (SSS), periodic LP-SS signal may be beneficial for the following functionalities: (a) Radio Resource Management (RRM) measurements by LP-WUR, if supported; (b) At least coarse time synchronization of LP-WUR; (c) At least coarse frequency synchronization of LP-WUR. Additional periodic LP-SS system overhead may depend on LP-SS periodicity, system Bandwidth (BW), number of beams, and resource required to fulfil the target functionality, etc. Periodic signal if used for coarse synchronization may reduce the overhead of signal preceding Low-Power Wake-Up Signal (LP-WUS), if any. LP-SS may be designed to be common among UE groups, cell-specific, and further reduce system overhead. For LP-WUR that may receive existing PSS / SSS potentially assisted by Physical Broadcast Channel (PBCH) Demodulation Reference Signal (DM RS) / T racking Reference Signal (TRS) for synchronization, existing PSS / SSS potentially assisted by PBCH DMRS / TRS may be used for the above functionality. Periodic LP-SS coverage may be required to be equal or better than that of LP-WUS. For fine time and frequency synchronization, a signal, e.g., preamble, preceding or part of LP- WUS may be used.

[0056] Orthogonal Frequency Division Multiplexing Access (OFDMA) waveform may provide coverage for LP-WUS with lower resource overhead. LP-WUR receiving OFDMA waveform may reuse PSS / SSS to perform RRM measurement and synchronization avoiding the introduction of periodic LP-SS within the carrier. Timing error robustness may be further improved using a sliding window at the receiver.

[0057] For Rel-19, a work item has been agreed to specify the wake-up signal for both RRC Idle / lnactive and RRC Connected states: RP-234056, New WID: Low-power wake-up signal and receiver for NR (LP WUS / WUR). The objectives of the work item are the following. One objective is to specify an LP-WUS design commonly applicable to both IDLE / INACTIVE and CONNECTED modes (RAN1 , RAN4). Connected mode may be e.g., RRC connected mode. This objective may comprise to specify OOK, OOK-1 and / or OOK-4, based LP-WUS with overlaid OFDM sequence(s) over OOK symbol. The LP-WUS design may be required to ensure that for IDLE / INACTIVE operation, the same information may be delivered irrespective of LP-WUR type. The OFDM sequence may carry information. At least duty-cycled monitoring of LP-WUS may be supported. Another objective may be for IDLE / INACTIVE modes, to specify procedure and configuration of LP-WUS indicating paging monitoring triggered by LP-WUS, including at least configuration, sub-grouping and entry / exit condition for LP-WUS monitoring (RAN2, RAN1 , RAN3, RAN4). This may comprise to specify LP-SS with periodicity with Yms, that is, a number Y of milliseconds, for LP-WLIR, for synchronization and / or RRM for serving cell. (RAN1 , RAN4). LP- SS may be understood to be based on OOK-1 and / or OOK-4 waveform with or without overlaid OFDM sequences. Further down selection between with and without overlaid OFDM sequences may have to be done within the Work Item (Wl). It may be noted that, for LP-WLIR that may receive existing PSS / SSS, existing PSS / SSS may be used for synchronization and RRM instead of LP-SS. Y may be decided within Wl. 320ms may be the start point. This objective may also comprise to specify further RRM relaxation of UE main receiver (MR) for both serving and neighbor cell measurements, and UE serving cell RRM measurement offloaded from MR to LP- WUR, including the necessary conditions (RAN4, RAN2). Yet another objective may be for CONNECTED mode, to specify procedures to allow UE MR PDCCH monitoring triggered by LP- WUS including activation and deactivation procedure of LP-WUS monitoring (RAN2, RAN1). This objective may comprise to check in RAN#105 for potential Time Unit (TU) adjustment in RAN2. It may be noted that, in CONNECTED mode, UE MR ultra-deep sleep may be understood to not be considered, and UE RRM / Radio Link Monitoring (RLM) / Beam Failure Detection (BFD) / Channel State Information (CSI) measurements may be performed by the MR. It may be noted that the target coverage of LP-WUS and LP-SS may have to be the coverage of PUSCH for messages. It may also be noted that the optimization of LP-WUS signal design for idle / inactive mode may be prioritized over the optimization for connected mode. Yet another objective may be to specify the necessary RAN4 core requirement(s) to support the feature (RAN4). This objective may be further refined in RAN#103.

[0058] Harmonized LP-WUS design

[0059] The Wl objective on the LP-WUS design may be understood to refer to a “harmonized” WUS design which may allow the WUS to be decoded by either an envelope detection based, e.g., OOK, WUR, or and OFDM-based WUR, see Figure 4. Figure 4 is a schematic diagram depicting an illustration of unified LP-WUS design. This objective may comprise to specify OOK, OOK-1 and / or OOK-4, based LP-WUS with overlaid OFDM sequence(s) over OOK symbol.

[0060] This was introduced as a compromise for the opposing views of different parties. With the approach, the gNB may be required to always transmit a harmonized LP-WUS signal, where the On-periods for the OOK modulation may be understood to mean that OFDM subcarriers may be being transmitted and the Off-periods may be understood to mean that nothing may be being transmitted, but the LP-WUS signal may either be received by an OOK-based WUR or an OFDMbased WUR. In general, a UE may either implement one WUR type or both.

[0061] The OOK-based WUR may have somewhat lower energy consumption, but the OFDMbased WUR may have better link performance and coverage, see Figure 5. Figure 5 is a schematic diagram depicting an illustration of the different coverage for OOK-based WUR and OFDM-based WUR reception of the unified LP-WUS. As illustrated in Figure 5, the largest coverage is provided by the main receiver, which may receive the PDCCH, followed by the OFDM-based LP-WLIS coverage, and lastly by the OKK-based LP-WLIS coverage.

[0062] The OFDM-based WUS may also be more efficient than the OOK-based WUS, allowing for e.g., a) a larger WUS payload, b) more redundancy bits for improved decoding performance, c) multiple WUS monitoring occasions during one WUS monitoring occasion for OOK-based WUS, etc., see Figure 6. Figure 6 is a schematic diagram depicting an illustration of unified LP-WUS content. Figure 6 particularly illustrates a unified LP-WUS specified in 3GPP Release 19, with OOK modulation overlaid with OFDM symbols. The ‘ON’ periods of the OOK modulation may be achieved by transmission of an OFDM signal. Manchester coding is used in the figure.

[0063] Self-organizing network (SON) and Minimization of Drive Tests (MDT) UE reporting

[0064] Drive tests may be understood to be one of the more costly activities for mobile network operators. Drive tests may involve driving vehicles and measuring network performance using test UEs and may be traditionally used to optimize network planning by mapping measurement data to location information. MDT reporting may provide a remote approach to achieve the same in a much more cost-efficient way. With MDT reporting regular UEs may be requested to instead provide the measurement data needed, including Global Navigation Satellite Systems (GNSS) location information, if available. Based on the measurement reports, the network deployment and configuration may be modified to work better, e.g., discovering and removing coverage holes.

[0065] There may be two types of UE reporting, immediate MDT reporting, e.g., using the RRM measurement framework in RRC Connected state, or logged MDT, where a UE may store multiple measurements or reports in RRC IDLE or RRC Inactive state to be reported later, e.g., upon later successful connection to the network.

[0066] Self-organizing networks (SON) may be understood to be systems that may automatically configure, optimize, and fix problems that may arise themselves without human intervention, in order to reduce the complexity of managing large cellular networks. MDT measurement reports from UEs may be used as input for the automatic SON configuration of the network (NW).

[0067] Existing methods may result in underlying issues leading to an SHR being unresolved, and degrade the performance of a network.

[0092] DETAILED DESCRIPTION

[0093] As part of the development of embodiments herein, one or more challenges with the existing technology will first be identified and discussed.

[0094] As described above, MDT may be understood to be a commonly used tool to reduce the mobile network operator cost for deployment planning, network coverage and configuration optimization. For the Rel-19 Wake-Up Receiver (WUR), it may be unclear if the MDT report from the UE may be referring to measurements made using the WUR or the main receiver (MR).

[0095] Using WUR, a different receiver may be understood to be used for downlink monitoring and at a given time it may not be known to the network if the UE is using the main receiver (MR) or the wake-up receiver (WUR) for measurements and downlink monitoring. If WUR is enabled for the UE, it may likely be the case for all RRC states that the gNB may transmit both the LP-WUS and legacy PDCCH, and it may be understood to be up to the UE to monitor for LP-WUS using WUR or directly monitor PDCCH using MR. Therefore, using the legacy MDT reporting format may not be sufficient since the network may not be able to determine if the report was produced based on WUR use or MR use. Additionally, it may not be possible for the network to configure the UE to perform measurements for the MDT reporting only when it may be operating with WUR, which may be beneficial in the case in which the network may want to optimize network performances and configurations for UEs operating with WUR, or only when it may be operating with MR, which may be beneficial in case the network may want to filter out UE measurements performed while the UE was operating with WUR, or both when it may be operating with MR and WUR.

[0096] Further, WUR link performance, e.g., sync and RRM measurements on LP-SS, and LP- WUS reception upon paging, may most likely be worse than legacy MR performance, e.g., synchronization and RRM measurements on SSB, and PDCCH reception upon paging. The Rel- 19 WUR work item description states the LP-WUS reception may be required to match Msg3 PUSCH performance, which may be several decibels (dB) worse than paging PDCCH performance. Therefore, WUR coverage holes may be expected to be larger and WUR may therefore be required to be handled separately. For example, one use of MDT / SON may be to spot and remove coverage holes. WUR link performance may be worse than regular paging PDCCH performance, therefore the problem with coverage holes may be more prominent for WUR, see Figure 7. Figure 7 is a schematic diagram depicting an example of main receiver coverage and LP-WLIS coverage. As illustrated in Figure 7, the coverage provided by the main receiver, which may receive the PDCCH, may be understood to be larger than that of LP-WLIS coverage. For the network to avoid such coverage holes, to the extent possible, by adapting the WUR configuration parameters, the network may be required to be aware of WUR performance that UEs may experience and therefore WUR-specific MDT reporting may be required.

[0097] In some deployment scenarios, a UE may detect WUS, either OOK- or OFDM-based, or LP-SS from neighboring cells. Such information, together with the location information, may be useful for the network e.g., for network radio planning and configuration planning. It may further be beneficial for setting up hardware-based beam forming.

[0098] Certain aspects of the present disclosure and their embodiments may provide solutions to these or other challenges. Embodiments herein may be generally understood relate to WUR specific reporting for Self-Organizing Networks (SON) and Minimization of Drive Tests (MDT). Particularly, embodiments herein may relate to WUR-specific MDT logging and reporting, to enable both adaptation and / or optimization of the network deployment and planning, coverage and configuration optimization, for improving WUR performance. For example, with the WUR- specific MDT logging, reporting and / or measurements, UE LP-WUS misdetection may be discovered and the WUR configuration may be modified to remedy the problem, e.g., by increasing the Reference Signal Received Power (RSRP) threshold for WUR operation entry or increasing the LP-WUS duration or power, e.g., to achieve better link performance such that LP- WUS reception is not missed.

[0099] The WUR-specific MDT logging, reporting, measurements may include e.g., if the UE was in WUR operation, RSRP from WUR measurement, on LP-SS, LP-WUS, or SSB, if LP-WUS was detected but not the associated paging PDCCH+PDSCH, e.g., LP-WUS false alarm or PDCCH misdetection, etc..

[0100] Some of the embodiments contemplated will now be described more fully hereinafter with reference to the accompanying drawings, in which examples are shown. In this section, the embodiments herein will be illustrated in more detail by a number of exemplary embodiments. Other embodiments, however, are contained within the scope of the subject matter disclosed herein. The disclosed subject matter should not be construed as limited to only the embodiments set forth herein; rather, these embodiments are provided by way of example to convey the scope of the subject matter to those skilled in the art. It should be noted that the exemplary embodiments herein are not mutually exclusive. Components from one embodiment may be tacitly assumed to be present in another embodiment and it will be obvious to a person skilled in the art how those components may be used in the other exemplary embodiments.

[0101] Figure 8 depicts two non-limiting examples, in panel a) and panel b), respectively, of a wireless network or wireless communications network 100, sometimes also referred to as a wireless communications system, cellular radio system, or cellular network, in which embodiments herein may be implemented. The wireless communications network 100 may be a 5G system, 5G network, or Next Gen System or network. In other examples, the wireless communications network 100 may in addition, support other technologies such as, for example, Long-Term Evolution (LTE), e.g. LTE-M, LTE Frequency Division Duplex (FDD), LTE Time Division Duplex (TDD), LTE Half-Duplex Frequency Division Duplex (HD-FDD), LTE operating in an unlicensed band, such as LTE LAA, eLAA, feLAA and / or MulteFire. Yet in other examples, the wireless communications network 100 may further support other technologies such as, for example Wideband Code Division Multiple Access (WCDMA), Universal Terrestrial Radio Access (UTRA) TDD, Global System for Mobile communications (GSM) network, GSM / Enhanced Data Rates for GSM Evolution (EDGE) Radio Access Network (GERAN) network, Ultra-Mobile Broadband (UMB), EDGE network, network comprising of any combination of Radio Access Technologies (RATs) such as e.g. Multi-Standard Radio (MSR) base stations, multi-RAT base stations etc., any 3rd Generation Partnership Project (3GPP) cellular network, WiFi networks, Worldwide Interoperability for Microwave Access (WiMax), or any cellular network or system. The wireless communications network 100 may typically support MTC, eMTC, loT and / or NB-loT. Thus, although terminology from 5G / NR and LTE may be used in this disclosure to exemplify embodiments herein, this should not be seen as limiting the scope of the embodiments herein to only the aforementioned system.

[0102] The wireless communications network 100 may comprise a plurality of network nodes, whereof a first network node 111 is depicted in the non-limiting example of panel a) and panel b) of Figure 8. In some embodiments, the wireless communications network 100 may comprise other network nodes, such as for example, a second network node 112, as depicted in the non-limiting example of panel b) in Figure 8.

[0103] Any of the first network node 111 and the second network node 112 may be a radio network node. That is, a transmission point such as a radio base station, for example a gNB, or any other network node with similar features capable of serving a user equipment, such as a wireless device or a machine type communication device, in the wireless communications network 100. In some examples, any of the first network node 111 and the second network node 112 may be a distributed node, and may partially perform its functions in collaboration with a virtual node in a cloud 115.

[0104] In some embodiments, any of the first network node 111 and the second network node 112 may be another network node, such as e.g., and operation and management system (GAM) or Service Management and Orchestration (SMO) or from the core network node, e.g., Access and Mobility Management Function (AMF). In particular examples, the first network node 111 may be a radio network node, e.g., a gNB, and the second network node 112 may be an SMO, and OAM or a core network node, e.g., an AMF.

[0105] In yet other examples, one of the first network node 111 and the second network node 112 may be a gNB-Centralized Unit (CU) and the other of the first network node 111 and the second network node 112 may be a gNB-Distributed Unit (DU).

[0106] The wireless communications network 100 may cover a geographical area, which in some embodiments may be divided into cell areas, wherein each cell area may be served by a radio network node, although, one radio network node may serve one or several cells. In the example of Figure 8, the first network node 111 serves a cell 121 or first cell 121. In some examples, the wireless communications network 100 may comprise at least a second cell, which may be a neighboring cell 122. That is, neighboring cell to the first cell 121.

[0107] As radio network nodes, any of the first network node 111 and the second network node 112 may be of different classes, such as, e.g., macro base station, home base station or pico base station, based on transmission power and thereby also cell size. In some examples, any of the first network node 111 and the second network node 112 may serve receiving nodes with serving beams. Any of the first network node 111 and the second network node 112 may support one or several communication technologies, and its name may depend on the technology and terminology used. Any of the radio network nodes that may be comprised in the communications network 100 may be directly connected to one or more core networks, e.g., to one or more network nodes in the one or more core networks, such as a virtual network node.

[0108] A plurality of wireless devices may be located in the wireless communication network 100, whereof a wireless device 130, is depicted in the non-limiting example of Figure 8. The wireless device 130 comprised in the wireless communications network 100 may be a wireless communication device such as a 5G User Equipment (UE) or nUE, or a UE, which may also be known as e.g., mobile terminal, wireless terminal and / or mobile station, a mobile telephone, cellular telephone, or laptop with wireless capability, just to mention some further examples. The wireless device 130 may be, for example, portable, pocket-storable, hand-held, computer- comprised, or a vehicle-mounted mobile device, enabled to communicate voice and / or data, via the RAN, with another entity, such as a server, a laptop, a Personal Digital Assistant (PDA), or a tablet, Machine-to-Machine (M2M) device, a sensor, loT device, NB-loT device, device equipped with a wireless interface, such as a printer or a file storage device, modem, or any other radio network unit capable of communicating over a radio link in a communications system. The wireless device 130 comprised in the wireless communications network 100 may be enabled to communicate wirelessly in the wireless communications network 100. The communication may be performed e.g., via a RAN, and possibly the one or more core networks, which may be comprised within the wireless communications network 100. The wireless device 130 may be configured to communicate within the wireless communications network 100 with the first network node 111 over a first link 141 , e.g., a radio link. The first network node 111 may be configured to communicate within the wireless communications network 100 with the second network node 112 over a second link 142, e.g., a radio link or a wired link. The wireless device 130 may be configured to communicate within the wireless communications network 100 with the second network node 112 over a third link 143, e.g., a radio link.

[0121] The report may comprise an indication. The indication, which may be referred to herein as a “third indication”, or simply “indication”, may be comprised in the information, be the same as the information, or be separate from the information.

[0122] The indication indicates that the one or more first measurements have been made with a wake-up receiver (WUR).

[0123] In some embodiments, the information may indicate one or more of the following: that low power wake-up signal (WUS) may be being monitored, first time information of WUR operation, second time information of low power synchronization signal (LP-SS), third time information of synchronization signal block (SSB), location information at a time of measurement, signal strength of the one or more radio signals, whether at least a subset of the one or more radio signals may be from a neighboring cell 122, that the signal strength may be of WUS, that the WUR may be a first On / Off keying (OOK) based WUR or a second Orthogonal Frequency Division Multiplexing (OFMD) based WUR, that WUS measurements may correspond to the first OOK-based WUR or to the second OFDM-based WUR, that the wireless device 130 may be entering or exiting WUR operation, that the signal strength may exceed a threshold, that the signal strength may be under the threshold, a first condition used to trigger WUS monitoring, a second condition to stop WUS monitoring, a first failure of LP-SS measurement or synchronization, a second failure of SSB measurement or synchronization, a time of transition from sleep state to WUS detection, and that WUS may have been detected in absence of a following Physical Downlink Control Channel (PDCCH), or Paging Early indication (PEI).

For example, the wireless device 130 may add additional information in the report than that indicated as second information in the second indication. That is, additional information than that requested by the first network node 111 to report. This may be for example, since the wireless device 130 may be configured by a different network node than the first network node 111 the wireless device 130 send the report to. Any reference to “information” in the description of Figures 9-14 herein, if not preceded by “first” or “second”, may be understood to refer to the third information.

[0135] According to examples herein, the wireless device 130, e.g., a WUR UE, may be configured to provide logged reports, e.g., based on periodic WUR measurements of LP-SS and events such as the wireless device 130 moving in and out of WUR coverage, WUR entry and / or exit, and / or immediate WUR MDT reports upon LP-WUS detection, e.g., reporting the RSRP measured by WUR at the time of LP-WUS reception; “and / or” meaning the mechanisms may be configured independently.

[0136] In some embodiments, the second indication may indicate at least one of the following: i) whether the information may have to be logged, obtained or both, periodically or based on one or more events, ii) to only collect information pertaining to WUS, iii) to only perform one or more measurements, e.g., the one or more first measurements, on WUS, iv) to only report the one or more first measurements when operating with one of the WUR and MR, v) to only log, obtain or both the one or more measurements, e.g., the one or more first measurements, when operating with the WUR, and vi) to only log, obtain or both, one or more second measurements when operating with MR.

[0137] The configuration indicated by the second indication in this Action 902 may comprise signalling to configure UEs such as the wireless device 130 to perform the WUR-specific MDT reporting, either logged reporting or immediate reporting as shown below, see next section.

[0138] Example related to the configuration

[0139] In an example of embodiments herein, the wireless device 130 enabled with the WUS operation, may log the WUS related information and measurements in a report upon receiving a first configuration from a network node such as the first network node 111. The first configuration may comprise one or more of the following.

[0140] According to one option, the first configuration may comprise an indication, e.g., a fourth indication, indicating the wireless device 130 to log the WUS related information. The (fourth) indication may explicitly indicate the type of the WUS, e.g., OOK based and / or OFDM based, measurement and information to be logged.

[0141] According to another option, the first configuration may comprise an indication, e.g., a fourth indication indicating whether the WUS related information and measurements may have to be logged periodically or based on an event and / or threshold. In some examples, the threshold may be related to the RSRP measurements of the WUS signals. In a non-limiting example, the network, e.g., the first network node 111 , may configure the wireless device 130 to log the WUS related measurements, e.g., RSRP, if the measured RSRP is below or above a certain configured threshold. In another non-limiting example, the network, e.g., the first network node 111 , may configure the wireless device 130 to log the WUS related measurements, e.g., RSRP, if the measured RSRP may be in between a lower threshold and upper thresholds configured by the network, e.g., the first network node 111 , e.g., RSRP_thr_1 < measured_RSRP of WUS < RSRP_thr_2.

[0142] In an example, the network, e.g., the first network node 111 , may configure the wireless device 130, to only collect the measurement and information associated to the WUS signals. In this example, the wireless device 130 may not need to collect the MDT measurements for the other radio resources e.g., neighboring cells measurements.

[0143] In an example of embodiments herein, the wireless device 130 may receive a second configuration from a network node, e.g., the first network node 111. The second configuration may comprise an indication, e.g., a fifth indication, to log information and measurement only when the wireless device 130 may be operating in MR mode.

[0144] In one example, if the first configuration may not be provided to the wireless device 130 or if the second configuration may not contain any configuration for the wireless device 130 to log the information and measurements while operating in WUS operation, the wireless device 130 may consider itself to be configured to not log information and measurements when operating in WUS operation.

[0145] In an example of embodiments herein, the wireless device 130 may be configured with the first and the second configuration. In such case, the wireless device 130 may log information and measurements associated to WUS operation when operating in WUS mode, and information and measurements associated to MR operation when operating in MR mode. In such case, the wireless device 130 may include in the report information and measurements associated to WUS operation and information and measurements associated to MR operation in separate information elements, or it may include an indication, that is, the third indication, indicating whether certain information and / or measurements may be associated to WUS or MR operations at a given point in time.

[0146] In some examples of the method of any of the previous methods, the indication, e.g., the third indication, that the information and measurements were logged when operating in MR or WUR mode or were not logged when operating in MR or WUR mode may be indicated per serving cell or camping cell, or neighboring, non-serving or non-camping cell.

[0147] Action 903

[0148] In this Action 903, wireless device 130 may receive one or more radio signals. The one or more radio signals, may be, e.g., broadcasted SSB, LP-SS, or LP-WUS. The receiving in this Action 903 may be, e.g., from the first network node 111.

[0149] The receiving, e.g., detecting, in this Action 903 may be performed, e.g., via the first link

[0150] 141.

[0151] Action 904

[0152] In this Action 904, wireless device 130 may obtain, log or both, the first information.

[0153] The obtaining, logging or both in this Action 904 may be based on the received one or more radio signals.

[0154] The obtaining, logging or both in this Action 904 may be performed, e.g., via the first link 141.

[0155] In an example according to embodiments herein, a method may be performed by the wireless device 130, e.g., a wireless terminal or a so-called a user equipment (UE). The method may comprise logging one or more measurements and / or first information concerning the WUS operation optimizations.

[0156] The method may comprise the wireless device 130 logging and performing data collection, of periodic measurements and events, and the associated reporting, which reporting will be described in Action 905.

[0157] In some embodiments, the information may indicate one or more of the following. This may be understood to apply to embodiments related to the measurement, in this Action 904, and / or report, in Action 905. In the following description of this Action 904, “information” may be understood to apply as well to first information.

[0158] According to an option, the information may indicate that low power (LP) wake-up signal (WUS) may be being monitored. For example, the wireless device 130 may log and perform data collection on whether LP-WUS may be being monitored by the wireless device 130 or not. For example, the wireless device 130 may log and perform data collection on whether e.g., the wireless device 130 may be in WUR operation, or whether legacy paging may be being monitored, e.g., PDCCH+PDSCH using MR. In another example, the information may indicate whether the wireless device 130 may be using the WUR+PEI feature combination and monitored both LP- WUS and PEI. In yet another example, the information may indicate that WUS detected but not the associated PDCCH, e.g., suspected LP-WUS false alarm.

[0159] According to another option, the information may indicate the first time information of WUR operation. For example, the wireless device 130 may include time information on when the wireless device 130 may have been in WUR operation. This information may for example be used in combination with logs of transmitted LP-WUS by the network, e.g., the first network node 111 , to deduce that LP-WUS was transmitted to the wireless device 130 but not successfully received by the wireless device 130, e.g., LP-WUS misdetection, and that the RSRP threshold for WUR operation entry may need to be modified. In some examples, the wireless device 130 may perform the one or more second measurements on the one or more radio signals. The wireless device 130 may use MR, e.g., the MR, to perform the one or more second measurements.

[0160] In another example that may involve immediate WUR MDT reporting, e.g., of UE experience upon LP-WLIS reception or event, the information may indicate whether LP-WLIS may be monitored by the wireless device 130 or not, e.g., wireless device 130 in WUR operation, or legacy paging monitored, e.g., PDCCH+PDSCH using MR. In a particular example, the indication may include time information on when the wireless device 130 may have been in WUR operation.

[0161] According to another option, the information may indicate the second time information of LP-SS. The second time information of LP-SS may comprise time information at LP-SS measurement, for OOK-based WUR.

[0162] It may be noted that time information may be absolute, e.g., clock time, or relative, e.g., given by Hyper System Frame Number (H-SFN), System Frame Number (SFN), and subframe number

[0163] According to another option, the information may indicate the third time information of SSB. The third time information of SSB may be collected using WUR. The third information of SSB may comprise time information at SSB measurement, e.g., for OFDM-based WUR.

[0164] In another example, the information may indicate time information at LP-WUS reception and / or detection.

[0165] According to another option, the information may indicate the location information at the time of measurement. The location information at the time of measurement may refer to measurement collected using WUR. The location information at the time of measurement may comprise, for example, a) location of the wireless device 130 at the time of LP-SS measurement, e.g., for OOK-based WUR, b) location of the wireless device 130 at the time of SSB measurement, e.g., for OFDM-based WUR, c) location of the wireless device 130 at the time of LP-WUS reception and / or detection.

[0166] According to another option, the information may indicate the signal strength of the one or more radio signals. The signal strength of the one or more radio signals may comprise, for example, a) RSRP measured by WUR on LP-SS at the time of measurement, e.g., for OOK- based WUR, b) RSRP measured by WUR on SSB at the time of measurement, e.g., for OFDMbased WUR, c) RSRP measured by WUR on LP-SS at the time of LP-WUS reception, for OOK- based WUR, d) RSRP measured by WUR on SSB at the time of LP-WUS reception, for OFDMbased WUR, e) RSRP measured by MR on SSB at the time of LP-WUS reception, potentially mapped to WUR performance, e.g., estimated LP-SS and / or LP-WUS reception performance.

[0167] RSRP may be the most likely metric to be adopted for the WUR reporting, but may be interchangeable with any other signal strength, or quality, measure such as Received Signal Strength Indicator (RSSI), Reference Signal Received Quality (RSRQ), Signal to Interference and Noise Ratio (SINR), etc.

[0168] According to another option, the information may indicate whether at least a subset of the one or more radio signals may be from the neighboring cell 122. This may comprise for example, whether the wireless device 130 may detect WUS-related signals from neighboring cells and which cells those may be. In one example this may be a list of neighboring cells where the wireless device 130 may detect an OOK-based WUS. In another example, this may be a list of neighboring cells where the wireless device 130 may detect LP-SS. In another example, this may be a list of neighboring cells where the wireless device 130 may detect an OFDM-based WUS. In one example, the wireless device 130 may further log the detected signal strength of any of the signals in the above examples. This information may be logged in the list together with information about the cell.

[0169] According to another option, the information may indicate that the signal strength may be of WUS. This may be indicated by an indication, e.g., a sixth indication, and / or flag indicating whether the collected RSRP measurements may be associated to the WUS signals or it may be one or more legacy RSRP measurements performed as part of cell selection and / or reselection procedure.

[0170] According to another option, the information may indicate that the WUR may be the first OOK based WUR or the second OFMD based WUR. This may be indicated by an indication, e.g., the third indication, and / or flag indicating whether the WUS related measurements may be associated to the OOK-based WUR or OFDM based WUR.

[0171] According to another option, the information may indicate that WUS measurements may correspond to the first OOK-based WUR or to the second OFDM-based WUR.

[0172] According to another option, the information may indicate that the wireless device 130 may be entering or exiting WUR operation.

[0173] According to another option, the information may indicate the that the signal strength may exceed the threshold.

[0174] According to another option, the information may indicate that the signal strength may be under the threshold. For example, the information may indicate that the WUR RSRP of the wireless device 130 may be moving above or below a preconfigured threshold, combined with the time information, location, measured RSRP, etc.

[0175] According to another option, the information may indicate the first condition used to trigger WUS monitoring. For example, the information may indicate the previous entry condition the wireless device 130 may have used to trigger WUS monitoring. Especially in case there may be multiple configured conditions, and the wireless device 130 may use different triggering conditions. Alternatively, a list of A / previous used entry conditions. According to another option, the information may indicate the second condition to stop WUS monitoring. For example, the information may indicate the previous exit conditions the wireless device 130 may have used to stop WUS monitoring. Especially in case there may be multiple configured conditions, and the wireless device 130 may use different triggering conditions. Alternatively, a list of A / previous used exit conditions. It may be understood here that “N” may be used herein to refer to different numbers in different examples.

[0176] According to another option, the information may indicate the first failure of LP-SS measurement or synchronization. For example, this may include reporting of LP-SS WUR measurement or synchronization failures, e.g., for OOK-based WUR. In more detail configured values for a timer, T, or a number of failed attempts, N, or a combination of a number of failed attempts within a certain time, may be used to define when UEs such as the wireless device 130 may have to report a failure. Further, the wireless device 130 may report the number of failures within a certain, fixed or configurable, time period.

[0177] According to another option, the information may indicate the second failure of SSB measurement or synchronization. For example, this may include reporting of SSB WUR measurement or synchronization failures, e.g., for OFDM-based WUR. In more detail, configured values for a timer, T, or a number of failed attempts, N, or a combination of a number of failed attempts within a certain time, may be used to define when UEs such as the wireless device 130 may have to report a failure. Further, the wireless device 130 may report the number of failures within a certain, fixed, or configurable, time period.

[0178] According to another option, the information may indicate the time of transition from sleep state to WUS detection. For example, this may include transition time from the sleep state of the UEs, such as the wireless device 130, upon LP-WUS detection.

[0179] In some examples, the first information indicating whether the wireless device 130 may be using the WUR+PEI feature combination and monitored both LP-WUS and PEI.

[0180] According to another option, the information may indicate that WUS may have been detected in absence of the following PDCCH or PEI. For example, this may include the first information indicating that a) WUS detected but not the associated PDCCH, e.g., suspected LP- WUS false alarm, b) WUS detected but not PEI, for WUR+PEI feature combination.

[0181] In an example, the network, e.g., the first network node 111 , may configure the wireless device 130, to only collect the measurement and information associated to the WUS signals. In this example, the wireless device 130 may not need to collect the MDT measurements for the other radio resources e.g., neighboring cells measurements. In one example, in response to receiving the above first configuration, the wireless device 130 may start logging the WUS related information and measurements according to the first configuration upon entering the WUR operation mode, and may stop the logging of the WUS related information and measurements upon exiting the WUR operation mode, e.g. upon entering the MR mode. In one dependent example, the wireless device 130 may not stop the logging of the WUS related information, rather the wireless device 130 may not log information and measurements if the wireless device 130 is in MR mode at a given point in time, e.g., at the point of time in which the wireless device 130 may be configured to perform the measurement, e.g. periodic measurement, and it may log again information and measurements if the wireless device 130 is back in WUR operation mode. For example, the wireless device 130 may indicate in the logged measurement results that the wireless device 130 may not have performed any measurement at a given point in time, with the cause being the wireless device 130 in MR mode.

[0182] In response to receiving the above second configuration, the wireless device 130 may start logging information and measurements according to the second configuration upon entering the MR operation mode, and may stop the logging upon exiting the MR operation mode, e.g., entering the WUR operation mode. In legacy, a UE may be configured for logged MDT, it may just start logging and it may continue until it may be in a configured area for logged MDT, irrespective of its receiver status. Here instead, with this example, the network (NW), e.g., the first network node 111 , may have at least the flexibility to configure the wireless device 130, such that it may not log anything if operating under WUR. In one dependent example, the wireless device 130 may not stop the logging upon entering the WUR operation mode, rather the wireless device 130 may not log information and measurements if the wireless device 130 is in WUR mode at a given point in time, e.g., at the point of time in which the wireless device 130 may be configured to perform the measurement, e.g., periodic measurement, and it may log again information and measurements if the wireless device 130 is back in MR operation mode. For example, the wireless device 130 may indicate in the logged measurement results that the wireless device 130 may not have performed any measurement at a given point in time, with the cause being the wireless device 130 in WUR mode.

[0183] As stated earlier, in an example of embodiments herein, the wireless device 130 may be configured with the first and the second configuration. In such case, the wireless device 130 may log information and measurements associated to WUS operation when operating in WUS mode, and information and measurements associated to MR operation when operating in MR mode. In such case, the wireless device 130 may include in the report information and measurements associated to WUS operation and information and measurements associated to MR operation in separate information elements, or it may include an indication, as an example of the third indication, indicating whether certain information and / or measurements may be associated to WUS or MR operations at a given point in time.

[0184] Action 905

[0185] In this Action 905, wireless device 130 sends the report, e.g., a WUR MDT report. The report comprises the information. The information one or more of: pertains, indicates, characterizes, and is about the one or more first measurements. The one or more first measurements may be understood to be the one or more measurements the wireless device 130 may report in this Action 905. The information may be WUR-specific information. That is the report may carry WUR-specific information.

[0186] The one or more first measurements have been performed by the wireless device 130, on one or more radio signals. The one or more radio signals may have been sent by the first network node 111.

[0187] The sending in this Action 905 is to the first network node 111 operating in the wireless communications network 100.

[0188] The report is of one of Minimization of Drive tests and Self-Organizing networks.

[0189] The report comprises the indication, that is, the third indication.

[0190] The (third) indication indicates that the one or more first measurements have been made with a wake-up receiver (WUR). The (third) indication may be an explicit, indication. In some examples, the indication may be implicit.

[0191] In some examples wherein the report may indicate the one or more first measurements and the one or more second measurements, the (third) indication may indicate that the one or more measurements have been made with the WUR or with the MR.

[0192] In one example, the WUR MDT report may be optional, e.g., in some instances, and may not be sent if MR is used for measurements and downlink monitoring, e.g., WUR operation may be implicit from the inclusion of the report. In one example, the (third) indication may be a flag indication or bit indication to inform the network, e.g., the first network node 111 , if the MDT report may be based on WUR measurement or, e.g., in examples wherein the report may indicate the one or more first measurements and the one or more second measurements, MR measurement, e.g., reusing the legacy MDT reporting format, this may be achieved with the extension of a 1 -bit indication, see example below. If the wireless device 130 is capable of both OOK-based WUR operation and OFDM-based WUR operation, a multibit indication may be used to further distinguish this, e.g., 2-bit indication if measurement may be done by MR, OOK-based WUR, OFDM-based WUR, or spare value. Also the number of receiving antenna branches used, if the wireless device 130 is monitoring both LP-WUS and PEI, e.g., feature combination, and other information may be other potential additional information, requiring more signalling bits in the extension.

[0193] The report sent may comprise one or more of: the obtained, logged or both second information, and a subset of the first information. The information included in the report may be referred to as “third information”.

[0194] Herein, MDT may be used as the example, but MDT may be understood to be closely related to Self-Organizing Networks (SON) reporting and therefore MDT may be understood to be interchangeable by SON reports above. In another example, the above information and measurements related to the WUS may be logged in the random access report if the wireless device 130, after receiving and / or detecting a WUS signal or signals may perform a random access procedure.

[0195] Embodiments herein may comprise changes and extensions to MDT UE reporting, see section below.

[0196] In some embodiments, the (third) information may indicate one or more of the following: that low power wake-up signal (WUS) may be being monitored, the first time information of WUR operation, the second time information of low power synchronization signal (LP-SS), the third time information of synchronization signal block (SSB), the location information at the time of measurement, the signal strength of the one or more radio signals, whether at least the subset of the one or more radio signals may be from the neighboring cell 122, that the signal strength may be of WUS, that the WUR may be the first OOK based WUR or the second OFMD based WUR, that WUS measurements may correspond to the first OOK-based WUR or to the second OFDM-based WUR, that the wireless device 130 may be entering or exiting WUR operation, that the signal strength may exceed the threshold, that the signal strength may be under the threshold, the first condition used to trigger WUS monitoring, the second condition to stop WUS monitoring, the first failure of LP-SS measurement or synchronization, the second failure of SSB measurement or synchronization, the time of transition from sleep state to WUS detection, and that WUS may have been detected in absence of the following PDCCH, or PEI.

[0197] As a particular example of that the (third) information may indicate that low power WUS may be being monitored, a 1-bit indication, as an example of the third indication, may indicate that the MDT report may be based on WUR measurement, potentially more bits adding details on: OFMD- based WUR, OOK-based WUR, number (Nr) of receiving antenna branches, etc.

[0198] Any of the examples described earlier, e.g., in relation to Action 904, may be included in the report.

[0199] In some embodiments, one of the following may apply. According to an option, the wireless device 130 may refrain from sending a report, e.g., a second report, on one or more second measurements performed of the one or more radio signals; the wireless device 130 may refrain from sending the report on the one or more second measurements with the proviso the wireless device 130 may have used the MR to perform the one or more second measurements. In one example, the WUR MDT report may be optional, e.g., in some instances, and it may be not sent if MR may be used for measurements and downlink monitoring, e.g., WUR operation may be implicit from the inclusion of the report.

[0200] According to another option, the report may indicate the one or more second measurements performed by the wireless device 130 with MR, e.g., the MR. In some embodiments, the sending in this Action 905 of the report may be one of: immediate and logged. Such embodiments may comprise examples of immediate WUR MDT reporting, e.g., of wireless device 130 experience upon LP-WLIS reception or event. In such examples, according to one option, the (third) indication may indicate whether LP-WLIS may be monitored by the wireless device 130 or not, e.g., wireless device 130 in WUR operation, or legacy paging monitored, e.g., PDCCH+PDSCH using MR, e.g., in the examples wherein the report may indicate the one or more first measurements performed with the WUR and the one or more second measurements performed by the wireless device 130 with the MR. In some examples, the (third) indication may include time information on when the wireless device 130 may have been in WUR operation. In one example, the WUR MDT report may be optional, e.g., in some instances, and may not be sent if MR is used for measurements and downlink monitoring, e.g., WUR operation may be implicit form the inclusion of the report. In some examples, the (third) indication may indicate whether the wireless device 130 may be using the WUR+PEI feature combination and monitored both LP-WUS and PEI. According to other options, the (third) indication may indicate one or more of: time information at LP-WUS reception and / or detection, location of the wireless device 130 at the time of LP-WUS reception and / or detection, RSRP measured by WUR on LP-SS at the time of LP-WUS reception, for OOK-based WUR, RSRP measured by WUR on SSB at the time of LP-WUS reception, for OFDM-based WUR, RSRP measured by MR on SSB at the time of LP-WUS reception, potentially mapped to WUR performance, e.g., estimated LP-SS and / or LP-WUS reception performance, WUS detected but not the associated PDCCH, e.g., suspected LP-WUS false alarm, WUS detected but not PEI, for WUR+PEI feature combination.

[0201] In some examples, the (third) indication may comprise reporting of the events, for example, the wireless device 130 entering or exiting WUR operation, combined with the time information, location, measured RSRP, etc. above.

[0202] In an addition to the above, the RSRP may be only reported if it may be with in a fixed or configurable delta from the RSRP-threshold configured for the WUR entry condition. The rationale for this may be understood to be to avoid unnecessary UL reporting and that the reports may be mainly of interest when the RSRP may be high enough such that the wireless device 130 may be using WUR for DL monitoring, but low enough that it may be problematic. In one example, RSRP reporting may be conditional on that the wireless device 130 may be in WUR operation and that the measured RSRP may be less than the WUR entry RSRP-threshold plus the new delta value, e.g., RSRPMeas RSRP-rhreshoid + RSRPoeita.

[0203] As stated earlier, in an example of embodiments herein, the wireless device 130 may be configured with the first and the second configuration. In such case, the wireless device 130 may log information and measurements associated to WUS operation when operating in WUS mode, and information and measurements associated to MR operation when operating in MR mode. In such case, the wireless device 130 may include in the report (third) information and measurements associated to WUS operation and (third) information and measurements associated to MR operation in separate information elements, or it may include an indication, that is, the third indication, indicating whether certain information and / or measurements may be associated to WUS or MR operations at a given point in time.

[0204] Signalling

[0205] In one example, the above changes to the MDT reporting format may be captured as an extension of the UElnformationReponse message (changes indicated in bold and underlined font).

[0216] The flag wurOperation may be included to indicate that the logged measurements logged at this time may be associated to measurements the wireless device 130 performed while in WUR operation mode. This method may be applicable in case for example, the wireless device 130 may be configured to perform information and measurement logging while in WUR operation mode. In another example of embodiments herein, the flag wurOperation may be included to indicate that the wireless device 130 may not have performed measurements at this time, since the wireless device 130 may have been in WUR operation mode. This method may be applicable in case for example, the wireless device 130 may need to not perform measurement logging while in WUR operation mode.

This method may be applicable in case for example, the wireless device 130 may be configured to perform information and measurement logging while in MR operation mode, and WUR operation mode.

[0218] In another example of embodiments herein, the flag mrOperation may be included to indicate that the wireless device 130 may not have performed measurements at this time, since the wireless device 130 may have been in MR operation mode. This method may be applicable in case for example, the wireless device 130 may need to not perform measurement logging while in MR operation mode.

[0219] In yet another example of embodiments herein, the said flags may be always in relationship to measured performed in the serving and / or camping cell, e.g., the wireless device 130 may indicate whether the measurements performed in the serving and / or camping may have been performed by the wireless device 130 while in MR or WUR operation mode. In another example, the said flags may also be associated to one or more of the neighbouring cells. For example, the wireless device 130 may indicate the list of cells for which the measurements may have been performed according to the WUR operation mode, and the list of cells for which the measurements may have been performed according to the MR operation mode.

[0509] Further Extensions And Variations

[0510] Figure 14 shows an example of a communication system 1400 in accordance with some embodiments.

[0511] In the example, the communication system 1400, such as the wireless communications network 100, includes a telecommunication network 1402 that includes an access network 1404, such as a radio access network (RAN), and a core network 1406, which includes one or more core network nodes 1408. The access network 1404 includes one or more access network nodes, such as the first network node 111 and / or the second network node 112 in some examples, such as network nodes 1410a and 1410b (one or more of which may be generally referred to as network nodes 1410), or any other similar 3rdGeneration Partnership Project (3GPP) access nodes or non-3GPP access points. Moreover, as will be appreciated by those of skill in the art, a network node is not necessarily limited to an implementation in which a radio portion and a baseband portion are supplied and integrated by a single vendor. Thus, it will be understood that network nodes include disaggregated implementations or portions thereof. For example, in some embodiments, the telecommunication network 1402 includes one or more Open-RAN (ORAN) network nodes. An ORAN network node is a node in the telecommunication network 1402 that supports an ORAN specification (e.g., a specification published by the O-RAN Alliance, or any similar organization) and may operate alone or together with other nodes to implement one or more functionalities of any node in the telecommunication network 1402, including one or more network nodes 1410 and / or core network nodes 1408.

[0512] Examples of an ORAN network node include an open radio unit (0-Rll), an open distributed unit (O-DU), an open central unit (O-CU), including an O-CU control plane (O-CU-CP) or an O- Cll user plane (O-CU-UP), a RAN intelligent controller (near-real time or non-real time) hosting software or software plug-ins, such as a near-real time control application (e.g., xApp) or a non- real time control application (e.g., rApp), or any combination thereof (the adjective “open” designating support of an ORAN specification). The network node may support a specification by, for example, supporting an interface defined by the ORAN specification, such as an A1 , F1 , W1 , E1 , E2, X2, Xn interface, an open fronthaul user plane interface, or an open fronthaul management plane interface. Moreover, an ORAN access node may be a logical node in a physical node. Furthermore, an ORAN network node may be implemented in a virtualization environment (described further below) in which one or more network functions are virtualized. For example, the virtualization environment may include an O-Cloud computing platform orchestrated by a Service Management and Orchestration Framework via an O-2 interface defined by the O- RAN Alliance or comparable technologies. The network nodes 1410 facilitate direct or indirect connection of user equipment (UE), such as by connecting UEs 1412a, 1412b, 1412c, and 1412d (one or more of which may be generally referred to as UEs 1412) to the core network 1406 over one or more wireless connections. Any of the UEs 1412a, 1412b, 1412c, and 1412d are examples of the wireless device 130.

[0513] Example wireless communications over a wireless connection include transmitting and / or receiving wireless signals using electromagnetic waves, radio waves, infrared waves, and / or other types of signals suitable for conveying information without the use of wires, cables, or other material conductors. Moreover, in different embodiments, the communication system 1400 may include any number of wired or wireless networks, network nodes, UEs, and / or any other components or systems that may facilitate or participate in the communication of data and / or signals whether via wired or wireless connections. The communication system 1400 may include and / or interface with any type of communication, telecommunication, data, cellular, radio network, and / or other similar type of system.

[0514] The wireless device 130, exemplified in Figure 14 as the UEs 1412 may be any of a wide variety of communication devices, including wireless devices arranged, configured, and / or operable to communicate wirelessly with any of the first network node 111 and / or the second network node 112 in some examples, exemplified in Figure 14 as network nodes 1410 and other communication devices. Similarly, the network nodes 1410 are arranged, capable, configured, and / or operable to communicate directly or indirectly with the UEs 1412 and / or with other network nodes or equipment in the telecommunication network 1402 to enable and / or provide network access, such as wireless network access, and / or to perform other functions, such as administration in the telecommunication network 1402.

[0515] In the depicted example, the core network 1406 connects the network nodes 1410 to one or more host computing systems, such as host 1416. These connections may be direct or indirect via one or more intermediary networks or devices. In other examples, network nodes may be directly coupled to hosts. The core network 1406 includes one more core network nodes (e.g., core network node 1408) that are structured with hardware and software components. Features of these components may be substantially similar to those described with respect to the UEs, network nodes, and / or hosts, such that the descriptions thereof are generally applicable to the corresponding components of the core network node 1408. Example core network nodes include functions of one or more of a Mobile Switching Center (MSC), Mobility Management Entity (MME), Home Subscriber Server (HSS), Access and Mobility Management Function (AMF), Session Management Function (SMF), Authentication Server Function (AUSF), Subscription Identifier Deconcealing function (SIDF), Unified Data Management (UDM), Security Edge Protection Proxy (SEPP), Network Exposure Function (NEF), and / or a User Plane Function (UPF). The host 1416 may be under the ownership or control of a service provider other than an operator or provider of the access network 1404 and / or the telecommunication network 1402. The host 1416 may host a variety of applications to provide one or more service. Examples of such applications include live and pre-recorded audio / video content, data collection services such as retrieving and compiling data on various ambient conditions detected by a plurality of UEs, analytics functionality, social media, functions for controlling or otherwise interacting with remote devices, functions for an alarm and surveillance center, or any other such function performed by a server.

[0516] As a whole, the communication system 1400 of Figure 14 enables connectivity between the UEs, network nodes, and hosts. In that sense, the communication system may be configured to operate according to predefined rules or procedures, such as specific standards that include, but are not limited to: Global System for Mobile Communications (GSM); Universal Mobile Telecommunications System (UMTS); Long Term Evolution (LTE), and / or other suitable 2G, 3G, 4G, 5G standards, or any applicable future generation standard (e.g., 6G); wireless local area network (WLAN) standards, such as the Institute of Electrical and Electronics Engineers (IEEE) 802.11 standards (WiFi); and / or any other appropriate wireless communication standard, such as the Worldwide Interoperability for Microwave Access (WiMax), Bluetooth, Z-Wave, Near Field Communication (NFC) ZigBee, LiFi, and / or any low-power wide-area network (LPWAN) standards such as LoRa and Sigfox.

[0517] In some examples, the telecommunication network 1402 is a cellular network that implements 3GPP standardized features. Accordingly, the telecommunications network 1402 may support network slicing to provide different logical networks to different devices that are connected to the telecommunication network 1402. For example, the telecommunications network 1402 may provide Ultra Reliable Low Latency Communication (URLLC) services to some UEs, while providing Enhanced Mobile Broadband (eMBB) services to other UEs, and / or Massive Machine Type Communication (mMTC) / Massive loT services to yet further UEs.

[0518] In some examples, the UEs 1412 are configured to transmit and / or receive information without direct human interaction. For instance, a UE may be designed to transmit information to the access network 1404 on a predetermined schedule, when triggered by an internal or external event, or in response to requests from the access network 1404. Additionally, a UE may be configured for operating in single- or multi-RAT or multi-standard mode. For example, a UE may operate with any one or combination of Wi-Fi, NR (New Radio) and LTE, i.e. being configured for multi-radio dual connectivity (MR-DC), such as E-UTRAN (Evolved-UMTS Terrestrial Radio Access Network) New Radio - Dual Connectivity (EN-DC).

[0519] In the example, the hub 1414 communicates with the access network 1404 to facilitate indirect communication between one or more UEs (e.g., UE 1412c and / or 1412d) and network nodes (e.g., network node 1410b). In some examples, the hub 1414 may be a controller, router, content source and analytics, or any of the other communication devices described herein regarding UEs. For example, the hub 1414 may be a broadband router enabling access to the core network 1406 for the UEs. As another example, the hub 1414 may be a controller that sends commands or instructions to one or more actuators in the UEs. Commands or instructions may be received from the UEs, network nodes 1410, or by executable code, script, process, or other instructions in the hub 1414. As another example, the hub 1414 may be a data collector that acts as temporary storage for UE data and, in some embodiments, may perform analysis or other processing of the data. As another example, the hub 1414 may be a content source. For example, for a UE that is a VR device, display, loudspeaker, or other media delivery device, the hub 1414 may retrieve VR assets, video, audio, or other media or data related to sensory information via a network node, which the hub 1414 then provides to the UE either directly, after performing local processing, and / or after adding additional local content. In still another example, the hub 1414 acts as a proxy server or orchestrator for the UEs, in particular if one or more of the UEs are low energy loT devices.

[0520] The hub 1414 may have a constant / persistent or intermittent connection to the network node 1410b. The hub 1414 may also allow for a different communication scheme and / or schedule between the hub 1414 and UEs (e.g., UE 1412c and / or 1412d), and between the hub 1414 and the core network 1406. In other examples, the hub 1414 is connected to the core network 1406 and / or one or more UEs via a wired connection. Moreover, the hub 1414 may be configured to connect to an M2M service provider over the access network 1404 and / or to another UE over a direct connection. In some scenarios, UEs may establish a wireless connection with the network nodes 1410 while still connected via the hub 1414 via a wired or wireless connection. In some embodiments, the hub 1414 may be a dedicated hub - that is, a hub whose primary function is to route communications to / from the UEs from / to the network node 1410b. In other embodiments, the hub 1414 may be a non-dedicated hub - that is, a device which is capable of operating to route communications between the UEs and network node 1410b, but which is additionally capable of operating as a communication start and / or end point for certain data channels.

[0521] Figure 15 shows a UE 1500 in accordance with some embodiments. The UE 1500 presents additional details of some embodiments of the UE 1412 of Figure 1 . As used herein, a UE refers to a device capable, configured, arranged and / or operable to communicate wirelessly with network nodes and / or other UEs. Examples of a UE include, but are not limited to, a smart phone, mobile phone, cell phone, voice over IP (VoIP) phone, wireless local loop phone, desktop computer, personal digital assistant (PDA), wireless cameras, gaming console or device, music storage / playback device, wearable terminal device, wireless endpoint, mobile station, tablet, laptop, laptop-embedded equipment (LEE), laptop-mounted equipment (LME), an Augmented Reality (AR) or Virtual Reality (VR) device, wireless customer-premise equipment (CPE), vehicle, vehicle-mounted or vehicle embedded / integrated wireless device, etc. Other examples include any UE identified by the 3rd Generation Partnership Project (3GPP), including a narrow band internet of things (NB-loT) UE, a machine type communication (MTC) UE, and / or an enhanced MTC (eMTC) UE.

[0522] A UE may support device-to-device (D2D) communication, for example by implementing a 3GPP standard for sidelink communication, Dedicated Short-Range Communication (DSRC), vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), or vehicle-to-everything (V2X). In other examples, a UE may not necessarily have a user in the sense of a human user who owns and / or operates the relevant device. Instead, a UE may represent a device that is intended for sale to, or operation by, a human user but which may not, or which may not initially, be associated with a specific human user (e.g., a smart sprinkler controller). Alternatively, a UE may represent a device that is not intended for sale to, or operation by, an end user but which may be associated with or operated for the benefit of a user (e.g., a smart power meter).

[0523] The UE 1500 includes processing circuitry 1502 that is operatively coupled via a bus 1504 to an input / output interface 1506, a power source 1508, a memory 1510, a communication interface 1512, and / or any other component, or any combination thereof. Certain UEs may utilize all or a subset of the components shown in Figure 15. The level of integration between the components may vary from one UE to another UE. Further, certain UEs may contain multiple instances of a component, such as multiple processors, memories, transceivers, transmitters, receivers, etc.

[0524] The processing circuitry 1502 is configured to process instructions and data and may be configured to implement any sequential state machine operative to execute instructions stored as machine-readable computer programs in the memory 1510. The processing circuitry 1502 may be implemented as one or more hardware-implemented state machines (e.g., in discrete logic, field-programmable gate arrays (FPGAs), application specific integrated circuits (ASICs), etc.); programmable logic together with appropriate firmware; one or more stored computer programs, general-purpose processors, such as a microprocessor or digital signal processor (DSP), together with appropriate software; or any combination of the above. For example, the processing circuitry 1502 may include multiple central processing units (CPUs).

[0525] In the example, the input / output interface 1506 may be configured to provide an interface or interfaces to an input device, output device, or one or more input and / or output devices. Examples of an output device include a speaker, a sound card, a video card, a display, a monitor, a printer, an actuator, an emitter, a smartcard, another output device, or any combination thereof. An input device may allow a user to capture information into the UE 1500. Examples of an input device include a touch-sensitive or presence-sensitive display, a camera (e.g., a digital camera, a digital video camera, a web camera, etc.), a microphone, a sensor, a mouse, a trackball, a directional pad, a trackpad, a scroll wheel, a smartcard, and the like. The presence-sensitive display may include a capacitive or resistive touch sensor to sense input from a user. A sensor may be, for instance, an accelerometer, a gyroscope, a tilt sensor, a force sensor, a magnetometer, an optical sensor, a proximity sensor, a biometric sensor, etc., or any combination thereof. An output device may use the same type of interface port as an input device. For example, a Universal Serial Bus (USB) port may be used to provide an input device and an output device.

[0526] In some embodiments, the power source 1508 is structured as a battery or battery pack. Other types of power sources, such as an external power source (e.g., an electricity outlet), photovoltaic device, or power cell, may be used. The power source 1508 may further include power circuitry for delivering power from the power source 1508 itself, and / or an external power source, to the various parts of the UE 1500 via input circuitry or an interface such as an electrical power cable. Delivering power may be, for example, for charging of the power source 1508. Power circuitry may perform any formatting, converting, or other modification to the power from the power source 1508 to make the power suitable for the respective components of the UE 1500 to which power is supplied.

[0527] The memory 1510 may be or be configured to include memory such as random access memory (RAM), read-only memory (ROM), programmable read-only memory (PROM), erasable programmable read-only memory (EPROM), electrically erasable programmable read-only memory (EEPROM), magnetic disks, optical disks, hard disks, removable cartridges, flash drives, and so forth. In one example, the memory 1510 includes one or more application programs 1514, such as an operating system, web browser application, a widget, gadget engine, or other application, and corresponding data 1516. The memory 1510 may store, for use by the UE 1500, any of a variety of various operating systems or combinations of operating systems.

[0528] The memory 1510 may be configured to include a number of physical drive units, such as redundant array of independent disks (RAID), flash memory, USB flash drive, external hard disk drive, thumb drive, pen drive, key drive, high-density digital versatile disc (HD-DVD) optical disc drive, internal hard disk drive, Blu-Ray optical disc drive, holographic digital data storage (HDDS) optical disc drive, external mini-dual in-line memory module (DIMM), synchronous dynamic random access memory (SDRAM), external micro-DIMM SDRAM, smartcard memory such as tamper resistant module in the form of a universal integrated circuit card (UICC) including one or more subscriber identity modules (SIMs), such as a USIM and / or ISIM, other memory, or any combination thereof. The UICC may for example be an embedded UICC (eUlCC), integrated UICC (iUICC) or a removable UICC commonly known as ‘SIM card.’ The memory 1510 may allow the UE 1500 to access instructions, application programs and the like, stored on transitory or non- transitory memory media, to off-load data, or to upload data. An article of manufacture, such as one utilizing a communication system may be tangibly embodied as or in the memory 1510, which may be or comprise a device-readable storage medium.

[0529] The processing circuitry 1502 may be configured to communicate with an access network or other network using the communication interface 1512. The communication interface 1512 may comprise one or more communication subsystems and may include or be communicatively coupled to an antenna 1522. The communication interface 1512 may include one or more transceivers used to communicate, such as by communicating with one or more remote transceivers of another device capable of wireless communication (e.g., another UE or a network node in an access network). Each transceiver may include a transmitter 1518 and / or a receiver 1520 appropriate to provide network communications (e.g., optical, electrical, frequency allocations, and so forth). Moreover, the transmitter 1518 and receiver 1520 may be coupled to one or more antennas (e.g., antenna 1522) and may share circuit components, software or firmware, or alternatively be implemented separately.

[0530] In the illustrated embodiment, communication functions of the communication interface 1512 may include cellular communication, Wi-Fi communication, LPWAN communication, data communication, voice communication, multimedia communication, short-range communications such as Bluetooth, near-field communication, location-based communication such as the use of the global positioning system (GPS) to determine a location, another like communication function, or any combination thereof. Communications may be implemented in according to one or more communication protocols and / or standards, such as IEEE 802.11 , Code Division Multiplexing Access (CDMA), Wideband Code Division Multiple Access (WCDMA), GSM, LTE, New Radio (NR), UMTS, WiMax, Ethernet, transmission control protocol / internet protocol (TCP / IP), synchronous optical networking (SONET), Asynchronous Transfer Mode (ATM), QUIC, Hypertext Transfer Protocol (HTTP), and so forth.

[0531] Regardless of the type of sensor, a UE may provide an output of data captured by its sensors, through its communication interface 1512, via a wireless connection to a network node. Data captured by sensors of a UE can be communicated through a wireless connection to a network node via another UE. The output may be periodic (e.g., once every 15 minutes if it reports the sensed temperature), random (e.g., to even out the load from reporting from several sensors), in response to a triggering event (e.g., when moisture is detected an alert is sent), in response to a request (e.g., a user initiated request), or a continuous stream (e.g., a live video feed of a patient).

[0532] As another example, a UE comprises an actuator, a motor, or a switch, related to a communication interface configured to receive wireless input from a network node via a wireless connection. In response to the received wireless input the states of the actuator, the motor, or the switch may change. For example, the UE may comprise a motor that adjusts the control surfaces or rotors of a drone in flight according to the received input or to a robotic arm performing a medical procedure according to the received input.

[0533] A UE, when in the form of an Internet of Things (loT) device, may be a device for use in one or more application domains, these domains comprising, but not limited to, city wearable technology, extended industrial application and healthcare. Non-limiting examples of such an loT device are a device which is or which is embedded in: a connected refrigerator or freezer, a TV, a connected lighting device, an electricity meter, a robot vacuum cleaner, a voice controlled smart speaker, a home security camera, a motion detector, a thermostat, a smoke detector, a door / window sensor, a flood / moisture sensor, an electrical door lock, a connected doorbell, an air conditioning system like a heat pump, an autonomous vehicle, a surveillance system, a weather monitoring device, a vehicle parking monitoring device, an electric vehicle charging station, a smart watch, a fitness tracker, a wearable for tactile augmentation or sensory enhancement, a water sprinkler, an animal- or item-tracking device, a sensor for monitoring a plant or animal, an industrial robot, an Unmanned Aerial Vehicle (UAV), and any kind of medical device, like a heart rate monitor or a remote controlled surgical robot. A UE in the form of an loT device comprises circuitry and / or software in dependence of the intended application of the loT device in addition to other components as described in relation to the UE 1500 shown in Figure 15.

[0534] As yet another specific example, in an loT scenario, a UE may represent a machine or other device that performs monitoring and / or measurements, and transmits the results of such monitoring and / or measurements to another UE and / or a network node. The UE may in this case be an M2M device, which may in a 3GPP context be referred to as an MTC device. As one particular example, the UE may implement the 3GPP NB-loT standard. In other scenarios, a UE may represent a vehicle, such as a car, a bus, a truck, a ship and an airplane, or other equipment that is capable of monitoring and / or reporting on its operational status or other functions associated with its operation.

[0535] In practice, any number of UEs may be used together with respect to a single example. For example, a first UE might be or be integrated in a drone and provide the drone’s speed information (obtained through a speed sensor) to a second UE that is a remote controller operating the drone. When the user makes changes from the remote controller, the first UE may adjust the throttle on the drone (e.g. by controlling an actuator) to increase or decrease the drone’s speed. The first and / or the second UE can also include more than one of the functionalities described above. For example, a UE might comprise the sensor and the actuator, and handle communication of data for both the speed sensor and the actuators.

[0536] Figure 16 shows a network node 1600 in accordance with some embodiments. As used herein, network node refers to equipment capable, configured, arranged and / or operable to communicate directly or indirectly with a UE and / or with other network nodes or equipment, in a telecommunication network. Examples of network nodes include, but are not limited to, access points (APs) (e.g., radio access points), base stations (BSs) (e.g., radio base stations, Node Bs, evolved Node Bs (eNBs) and NR NodeBs (gNBs)), O-RAN nodes or components of an O-RAN node (e.g., O-RU, O-DU, O-CU).

[0537] Base stations may be categorized based on the amount of coverage they provide (or, stated differently, their transmit power level) and so, depending on the provided amount of coverage, may be referred to as femto base stations, pico base stations, micro base stations, or macro base stations. A base station may be a relay node or a relay donor node controlling a relay. A network node may also include one or more (or all) parts of a distributed radio base station such as centralized digital units, distributed units (e.g., in an O-RAN access node) and / or remote radio units (RRUs), sometimes referred to as Remote Radio Heads (RRHs). Such remote radio units may or may not be integrated with an antenna as an antenna integrated radio. Parts of a distributed radio base station may also be referred to as nodes in a distributed antenna system (DAS).

[0538] Other examples of network nodes include multiple transmission point (multi-TRP) 5G access nodes, multi-standard radio (MSR) equipment such as MSR BSs, network controllers such as radio network controllers (RNCs) or base station controllers (BSCs), base transceiver stations (BTSs), transmission points, transmission nodes, multi-cell / multicast coordination entities (MCEs), Operation and Maintenance (O&M) nodes, Operations Support System (OSS) nodes, Self-Organizing Network (SON) nodes, positioning nodes (e.g., Evolved Serving Mobile Location Centers (E-SMLCs)), and / or Minimization of Drive Tests (MDTs).

[0539] The network node 1600 includes a processing circuitry 1602, a memory 1604, a communication interface 1606, and a power source 1608. The network node 1600 may be composed of multiple physically separate components (e.g., a NodeB component and a RNC component, or a BTS component and a BSC component, etc.), which may each have their own respective components. In certain scenarios in which the network node 1600 comprises multiple separate components (e.g., BTS and BSC components), one or more of the separate components may be shared among several network nodes. For example, a single RNC may control multiple NodeBs. In such a scenario, each unique NodeB and RNC pair, may in some instances be considered a single separate network node. In some embodiments, the network node 1600 may be configured to support multiple radio access technologies (RATs). In such embodiments, some components may be duplicated (e.g., separate memory 1604 for different RATs) and some components may be reused (e.g., a same antenna 1610 may be shared by different RATs). The network node 1600 may also include multiple sets of the various illustrated components for different wireless technologies integrated into network node 1600, for example GSM, WCDMA, LTE, NR, WiFi, Zigbee, Z-wave, LoRaWAN, Radio Frequency Identification (RFID) or Bluetooth wireless technologies. These wireless technologies may be integrated into the same or different chip or set of chips and other components within network node 1600.

[0540] The processing circuitry 1602 may comprise a combination of one or more of a microprocessor, controller, microcontroller, central processing unit, digital signal processor, application-specific integrated circuit, field programmable gate array, or any other suitable computing device, resource, or combination of hardware, software and / or encoded logic operable to provide, either alone or in conjunction with other network node 1600 components, such as the memory 1604, to provide network node 1600 functionality.

[0541] In some embodiments, the processing circuitry 1602 includes a system on a chip (SOC). In some embodiments, the processing circuitry 1602 includes one or more of radio frequency (RF) transceiver circuitry 1612 and baseband processing circuitry 1614. In some embodiments, the radio frequency (RF) transceiver circuitry 1612 and the baseband processing circuitry 1614 may be on separate chips (or sets of chips), boards, or units, such as radio units and digital units. In alternative embodiments, part or all of RF transceiver circuitry 1612 and baseband processing circuitry 1614 may be on the same chip or set of chips, boards, or units.

[0542] The memory 1604 may comprise any form of volatile or non-volatile computer-readable memory including, without limitation, persistent storage, solid-state memory, remotely mounted memory, magnetic media, optical media, random access memory (RAM), read-only memory (ROM), mass storage media (for example, a hard disk), removable storage media (for example, a flash drive, a Compact Disk (CD) or a Digital Video Disk (DVD)), and / or any other volatile or non-volatile, non-transitory device-readable and / or computer-executable memory devices that store information, data, and / or instructions that may be used by the processing circuitry 1602. The memory 1604 may store any suitable instructions, data, or information, including a computer program, software, an application including one or more of logic, rules, code, tables, and / or other instructions capable of being executed by the processing circuitry 1602 and utilized by the network node 1600. The memory 1604 may be used to store any calculations made by the processing circuitry 1602 and / or any data received via the communication interface 1606. In some embodiments, the processing circuitry 1602 and memory 1604 is integrated.

[0543] The communication interface 1606 is used in wired or wireless communication of signaling and / or data between a network node, access network, and / or UE. As illustrated, the communication interface 1606 comprises port(s) / terminal(s) 1616 to send and receive data, for example to and from a network over a wired connection. The communication interface 1606 also includes radio front-end circuitry 1618 that may be coupled to, or in certain embodiments a part of, the antenna 1610. Radio front-end circuitry 1618 comprises filters 1620 and amplifiers 1622. The radio front-end circuitry 1618 may be connected to an antenna 1610 and processing circuitry 1602. The radio front-end circuitry may be configured to condition signals communicated between antenna 1610 and processing circuitry 1602. The radio front-end circuitry 1618 may receive digital data that is to be sent out to other network nodes or UEs via a wireless connection. The radio front-end circuitry 1618 may convert the digital data into a radio signal having the appropriate channel and bandwidth parameters using a combination of filters 1620 and / or amplifiers 1622. The radio signal may then be transmitted via the antenna 1610. Similarly, when receiving data, the antenna 1610 may collect radio signals which are then converted into digital data by the radio front-end circuitry 1618. The digital data may be passed to the processing circuitry 1602. In other embodiments, the communication interface may comprise different components and / or different combinations of components.

[0544] In certain alternative embodiments, the network node 1600 does not include separate radio front-end circuitry 1618, instead, the processing circuitry 1602 includes radio front-end circuitry and is connected to the antenna 1610. Similarly, in some embodiments, all or some of the RF transceiver circuitry 1612 is part of the communication interface 1606. In still other embodiments, the communication interface 1606 includes one or more ports or terminals 1616, the radio frontend circuitry 1618, and the RF transceiver circuitry 1612, as part of a radio unit (not shown), and the communication interface 1606 communicates with the baseband processing circuitry 1614, which is part of a digital unit (not shown).

[0545] The antenna 1610 may include one or more antennas, or antenna arrays, configured to send and / or receive wireless signals. The antenna 1610 may be coupled to the radio front-end circuitry 1618 and may be any type of antenna capable of transmitting and receiving data and / or signals wirelessly. In certain embodiments, the antenna 1610 is separate from the network node 1600 and connectable to the network node 1600 through an interface or port.

[0546] The antenna 1610, communication interface 1606, and / or the processing circuitry 1602 may be configured to perform any receiving operations and / or certain obtaining operations described herein as being performed by the network node. Any information, data and / or signals may be received from a UE, another network node and / or any other network equipment. Similarly, the antenna 1610, the communication interface 1606, and / or the processing circuitry 1602 may be configured to perform any transmitting operations described herein as being performed by the network node. Any information, data and / or signals may be transmitted to a UE, another network node and / or any other network equipment.

[0547] The power source 1608 provides power to the various components of network node 1600 in a form suitable for the respective components (e.g., at a voltage and current level needed for each respective component). The power source 1608 may further comprise, or be coupled to, power management circuitry to supply the components of the network node 1600 with power for performing the functionality described herein. For example, the network node 1600 may be connectable to an external power source (e.g., the power grid, an electricity outlet) via an input circuitry or interface such as an electrical cable, whereby the external power source supplies power to power circuitry of the power source 1608. As a further example, the power source 1608 may comprise a source of power in the form of a battery or battery pack which is connected to, or integrated in, power circuitry. The battery may provide backup power should the external power source fail.

[0548] Embodiments of the network node 1600 may include additional components beyond those shown in Figure 16 for providing certain aspects of the network node’s functionality, including any of the functionality described herein and / or any functionality necessary to support the subject matter described herein. For example, the network node 1600 may include user interface equipment to allow input of information into the network node 1600 and to allow output of information from the network node 1600. This may allow a user to perform diagnostic, maintenance, repair, and other administrative functions for the network node 1600. In some embodiments providing a core network node, such as core network node 108 of FIG. 14, some components, such as the radio front-end circuitry 1618 and the RF transceiver circuitry 1612 may be omitted.

[0549] Figure 17 is a block diagram illustrating a virtualization environment 1700 in which functions implemented by some embodiments may be virtualized. In the present context, virtualizing means creating virtual versions of apparatuses or devices which may include virtualizing hardware platforms, storage devices and networking resources. As used herein, virtualization can be applied to any device described herein, or components thereof, and relates to an implementation in which at least a portion of the functionality is implemented as one or more virtual components. Some or all of the functions described herein may be implemented as virtual components executed by one or more virtual machines (VMs) implemented in one or more virtual environments 1700 hosted by one or more of hardware nodes, such as a hardware computing device that operates as a network node, UE, core network node, or host. Further, in embodiments in which the virtual node does not require radio connectivity (e.g., a core network node or host), then the node may be entirely virtualized. In some embodiments, the virtualization environment 1700 includes components defined by the O-RAN Alliance, such as an O-Cloud environment orchestrated by a Service Management and Orchestration Framework via an O-2 interface. Virtualization may facilitate distributed implementations of a network node, UE, core network node, or host.

[0550] Applications 1702 (which may alternatively be called software instances, virtual appliances, network functions, virtual nodes, virtual network functions, etc.) are run in the virtualization environment Q400 to implement some of the features, functions, and / or benefits of some of the embodiments disclosed herein.

[0551] Hardware 1704 includes processing circuitry, memory that stores software and / or instructions executable by hardware processing circuitry, and / or other hardware devices as described herein, such as a network interface, input / output interface, and so forth. Software may be executed by the processing circuitry to instantiate one or more virtualization layers 1706 (also referred to as hypervisors or virtual machine monitors (VMMs)), provide VMs 1708a and 1708b (one or more of which may be generally referred to as VMs 1708), and / or perform any of the functions, features and / or benefits described in relation with some embodiments described herein. The virtualization layer 1706 may present a virtual operating platform that appears like networking hardware to the VMs 1708. The VMs 1708 comprise virtual processing, virtual memory, virtual networking or interface and virtual storage, and may be run by a corresponding virtualization layer 1706. Different embodiments of the instance of a virtual appliance 1702 may be implemented on one or more of VMs 1708, and the implementations may be made in different ways. Virtualization of the hardware is in some contexts referred to as network function virtualization (NFV). NFV may be used to consolidate many network equipment types onto industry standard high volume server hardware, physical switches, and physical storage, which can be located in data centers, and customer premise equipment.

[0552] In the context of NFV, a VM 1708 may be a software implementation of a physical machine that runs programs as if they were executing on a physical, non-virtualized machine. Each of the VMs 1708, and that part of hardware 1704 that executes that VM, be it hardware dedicated to that VM and / or hardware shared by that VM with others of the VMs, forms separate virtual network elements. Still in the context of NFV, a virtual network function is responsible for handling specific network functions that run in one or more VMs 1708 on top of the hardware 1704 and corresponds to the application 1702.

[0553] Hardware 1704 may be implemented in a standalone network node with generic or specific components. Hardware 1704 may implement some functions via virtualization. Alternatively, hardware 1704 may be part of a larger cluster of hardware (e.g. such as in a data center or CPE) where many hardware nodes work together and are managed via management and orchestration 1710, which, among others, oversees lifecycle management of applications 1702. In some embodiments, hardware 1704 is coupled to one or more radio units that each include one or more transmitters and one or more receivers that may be coupled to one or more antennas. Radio units may communicate directly with other hardware nodes via one or more appropriate network interfaces and may be used in combination with the virtual components to provide a virtual node with radio capabilities, such as a radio access node or a base station. In some embodiments, some signaling can be provided with the use of a control system 1712 which may alternatively be used for communication between hardware nodes and radio units.

[0555] The wireless device 130 may comprise an arrangement as shown in Figure 12 or in Figure 15.

[0556] The first network node 111 embodiments relate to Figure 10, Figure 11, Figure 13, and Figures 14-17.

[0557] The first network node 111 may comprise an arrangement as shown in Figure 13 or in Figure 16 or in Figure 17. Although the computing devices described herein (e.g., UEs, network nodes) may include the illustrated combination of hardware components, other embodiments may comprise computing devices with different combinations of components. It is to be understood that these computing devices may comprise any suitable combination of hardware and / or software needed to perform the tasks, features, functions and methods disclosed herein. Determining, calculating, obtaining or similar operations described herein may be performed by processing circuitry, which may process information by, for example, converting the obtained information into other information, comparing the obtained information or converted information to information stored in the network node, and / or performing one or more operations based on the obtained information or converted information, and as a result of said processing making a determination. Moreover, while components are depicted as single boxes located within a larger box, or nested within multiple boxes, in practice, computing devices may comprise multiple different physical components that make up a single illustrated component, and functionality may be partitioned between separate components. For example, a communication interface may be configured to include any of the components described herein, and / or the functionality of the components may be partitioned between the processing circuitry and the communication interface. In another example, non-computationally intensive functions of any of such components may be implemented in software or firmware and computationally intensive functions may be implemented in hardware.

[0558] In certain embodiments, some or all of the functionality described herein may be provided by processing circuitry executing instructions stored on in memory, which in certain embodiments may be a computer program product in the form of a non-transitory computer-readable storage medium. In alternative embodiments, some or all of the functionality may be provided by the processing circuitry without executing instructions stored on a separate or discrete device- readable storage medium, such as in a hard-wired manner. In any of those particular embodiments, whether executing instructions stored on a non-transitory computer-readable storage medium or not, the processing circuitry can be configured to perform the described functionality. The benefits provided by such functionality are not limited to the processing circuitry alone or to other components of the computing device, but are enjoyed by the computing device as a whole, and / or by end users and a wireless network generally.
