Description

[0001] FIRST WIRELESS DEVICE, NETWORK NODE, AND METHODS PERFORMED THEREBY, FOR HANDLING ONE OR MORE WAKE-UP SIGNALS

[0002] TECHNICAL FIELD

[0003] The present disclosure relates generally to a first wireless device and methods performed thereby for handling one or more wake-up signals. The present disclosure also generally relates to a network node and methods performed thereby for handling the one or more wakeup signals.

[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 Base Transceiver Station (BTS), 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] LP-WUS / WUR

[0009] A low power wake-up receiver (LP-WUR) or wake-up receiver(WUR), also referred to as ‘wake-up radio’, may be understood to involve use of a low-power receiver in UEs, which may detect a low power wake-up signal (LP-WUS) or a Wake-up signal (WUS) that may be understood to be specially designed to be highly energy efficient. The WUS may be used to activate the main receiver, that is, the baseband / Radio Frequency (RF) / less power efficient receiver, to carry out more complex communication or sensory functions. Typical actions after activation may be reception of an incoming paging indication on the Physical downlink Control Channel (PDCCH) during paging occasions (PO), further scheduling communication on the Physical downlink Shared Channel (PDSCH). As 5G-Advanced transitions to Sixth Generation (6G) in the next decade, there is a stated intention to introduce sensory functions into cellular radios capable of functionality that may allow environmental awareness, mapping, and the detection of objects or motion. The WUR may be mainly useful in lowering energy consumption and improving device battery life or trading off reduction of latency, through shorter discontinuous reception intervals, for fixed energy consumption by preventing more complex functions from operating unless needed.

[0010] Figure 1 is a schematic diagram illustrating location of a LP-WUS 11 , indicated by “WUS” in Figure 1 , and the paging occasion 12, indicated by “PO” in Figure 1 , to which it is associated. PO 12 that do not carry a paging indication, as indicated by the white PO boxes, may be understood to not be preceded by reception of an LP-WUS 11 , as indicated by the white WUS boxes, whereas a PO 12 carrying a paging indication, as indicated by the black PO box, may be understood to be preceded by reception of an LP WUS 11 , as indicated by the black WUS box. The WUR may have some or all of following characteristics. One characteristic may be extremely low power, simple and low-cost receiver architecture, relaxed requirements, noisier, that is, less accurate, clock or oscillator. Another characteristic may be significant power saving gain by maximizing the time in which the main receiver may be in the sleep mode. Yet another characteristic may be that they may be enablers for zero energy / battery-less devices, and energy harvesting operations. Yet another characteristic may be compromised coverage due to lower receiver sensitivity.

[0011] As an example, Figure 2 shows a dedicated wake up radio (WUR) may be used for monitoring a wake-up signal (WUS). Once the WUR detects the WUS as one likely addressed to itself, it may activate the main receiver, that is, the baseband / RF / less power efficient receiver, to detect further incoming messages. Thus, the main receiver may go to sleep mode and save power until it may be triggered by WUR. The ultra-low-power and low-complexity implementation may be understood to be the consequence of the design of the WUS, which may be understood to be based on simple modulation schemes, such as On-Off Keying (OOK), Frequency Shift Keying (FSK), or Phase Shift Keying (PSK), that may be easy to detect with minimum digital processing. The WUS may be itself transmitted using an Orthogonal Frequency Division Multiplexing (OFDM)- based transmitter from the network using equipment that may be shared with the base station for cellular communication.

[0012] Figure 2 is a schematic diagram illustrating a dedicate wake-up radio accompanying the main receiver; the figure is illustrative and does not represent a typical implementation; for instance, the antenna and some components in the RF front-end may be shared.

[0013] In Rel-18, there has been rather large interest to introduce WUR for NR, with an ambition for achieving more significant energy efficiency improvement compared to approaches already specified in earlier releases. As explained above, the only specification support needed to be able to use a WUR in the UE, may be the specification of a WUS and a sufficient time gap between the WUS and the PDCCH in the PO, to allow the UE to start up the main receiver. Therefore, the main difference to Rel-17 Paging Early Indication (PEI) may be understood to be that the WUS in Rel-18 may be required to not be PDCCH-based, that is, that PDCCH may be understood to not be the physical channel used for wake up indication, and allow for a simpler and low power receiver, that is, WUR with simple modulation and detection techniques, e.g., using OOK modulation and non-coherent detection.

[0014] In Rel-18, a study item on “low-power wake-up signal and receiver for NR” was approved.

[0015] The benefit of WUR may be understood to be to reduce the energy consumption of the receiver, such that unless there is any paging and data for the UE, it may remain in a power saving state. This may be understood to extend the battery life of the device, or alternatively enable shorter downlink latency, e.g., shorter DRX, at a fixed battery life.

[0016] The Rel-18 study item on “low-power wake-up signal and receiver for NR” is completed and the technical report is provided in: TR 38.869, v. 0.4.0, “Study on low-power Wake-up Signal and Receiver for NR” [2], Subsequently, there will be Rel-19 Work Item to specify the various design aspects of WUS / WUR. For Rel-19, a work item has been agreed to specify the wake-up signal for both Radio Resource Control (RRC) Idle / lnactive and RRC Connected states: RP-234056, New WID: Low-power wake-up signal and receiver for NR (LP WUS / WUR) [3], OOK-based and OFDM-based WUR low power receiver such as a wake-up receiver (WUR) may be understood to be expected to have limited capabilities in terms of supported modulation schemes, synchronization, and receiver architecture. For example, the WUR may only support a simple modulation scheme such as OOK and employ time domain envelope detection. Nevertheless, in some other cases, a low power wake-up receiver may be more capable, e.g., capable of receiving an OFDM-based signal or both OOK-based and OFDM-based signals. Specifically, there may be the following types of WUR. One type may be an OOK-based WUR, which may be understood to support OOK modulation and employ time domain envelope detection. It may require new low-power synchronization signal (LP-SS) for synchronization and measurements. LP-SS may use OOK waveform potentially with overlaid OFDM sequences. Another type may be an OFDM-based WUR, which may be understood to be a more capable receiver that may receive OFDM-based signals such as Primary Synchronization Signal (PSS) / Secondary Synchronization Signal (SSS), and capable of processing In-phase / Quadrature (l / Q) samples. For synchronization, existing PSS / SSS may be used. It may be noted that in NR, the synchronization signal block, SS block or SSB, may consist of primary and secondary synchronization signals, PSS and SSS, and Physical Broadcast Channel (PBCH). In addition, in yet another type of WUR, a UE may support both OOK WUR and OFDM WUR.

[0017] A UE may implement just one type of WUR, e.g., OOK-based or OFDM-based, or both types. The latter may be motivated by the better performance and coverage but slightly higher power of the OFDM-WUR. A gNB may have to support different UEs with supporting different WUR types. An illustrative figure for the unified LP-WUS design is shown in Figure 3. Figure 3 is a schematic diagram illustrating a unified LP-WUS design. As depicted in Figure 3, a gNB may support one UE supporting OOK-based WUR, and another UE supporting OFDM-based WUR, and transmit a unified LP-WUS.

[0018] To improve the coverage and interference mitigation, the gNB may transmit the unified WUS with beam sweeping, which may be detected by OOK WUR and OFDM WUR, e.g., as shown in Figure 4. Figure 4 is a schematic diagram illustrating beam sweeping for WUS. As illustrated in Figure 4, a gNB may perform beam sweeping for WUS by transmitting one beam, Beam 1 , at time 1 , another beam, Beam 2 at time 2, and yet another beam, Beam 3, at time 3. Different beams may refer to different spatial filter settings, e.g., Spatial Reception parameters, applied by the multi-antenna system of gNB or UE for transmitting or receiving LP-WUS. For example, if Beam X corresponds to SSB X and Beam Y corresponds to SSB Y, then the UE may use the same Spatial Reception parameters it may use for receiving SSB X for LP- WUS / LP-SS reception using Beam X. Similarly, it may use the same Spatial Reception parameters it may use for receiving SSB Y for LP-WUS / LP-SS reception using Beam Y.

[0047] DETAILED DESCRIPTION

[0048] As part of the development of embodiments herein, one or more challenges with the existing technology will first be identified and discussed.

[0049] Detailed design for efficient monitoring of LP-WUS using LP-WUS monitoring occasions (MOs) is lacking in existing technology.

[0050] 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 methods for monitoring of low power wake-up signal.

[0051] 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.

[0052] Figure 5 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, or a newer system with equivalent functionality, such as, e.g., a 6G system. 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 for Machines (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 Licensed Assisted Access (LAA), Enhanced LAA (eLAA), Further Enhanced LAA (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 Machine Type Communication (MTC), Enhanced MTC (eMTC), Internet of Things (loT) and / or NarrowBand loT (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.

[0053] 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 5. In some embodiments, the wireless communications network 100 may comprise a second network node 112, as depicted in the non-limiting example of panel b) in Figure 5. Herein any of the first network node 111 and the second network node 112 may be referred to as network node 111, 112.

[0054] 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.

[0055] In some embodiments, the second network node 112 may be another network node, such as e.g., an operation and management system (GAM) or Service Management and Orchestration (SMO) or a core network node, e.g., Access and Mobility Management Function (AMF).

[0056] 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. 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 5, the first network node 111 serves a cell 120.

[0057] 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.

[0058] A plurality of wireless devices 130 may be located in the wireless communication network 100. A first wireless device 131 is depicted in the non-limiting example of Figure 5, which may be one of the wireless devices 130. Any of the wireless devices 130 comprised in the wireless communications network 100, such as the first wireless device 131, 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 first wireless device 131 may be, for example, portable, pocket-storable, handheld, 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. Any of the wireless devices 130 comprised in the wireless communications network 100, such as the first wireless device 131, 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.

[0059] The first wireless device 131 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. Any of the wireless devices 130 may be configured to communicate within the wireless communications network 100 with the first network node 111 over a respective link, e.g., a radio link, which is not depicted in Figure 5 to simplify the figure. 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 first wireless device 131 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.

In Figure 6 optional actions may be represented with dashed lines.

[0071] Action 601

[0072] In this Action 601 , the first wireless device 131 may obtain information. The obtaining in this Action 601 may be, e.g., receiving, and may be performed, e.g., via the first link 141 , or it may be retrieving, e.g., from a memory of the first wireless device 131 , or a combination of both.

[0073] The obtaining in this Action 601 may be from higher layer signalling.

[0074] The obtaining in this Action 601 may be from the first network node 111 , or from the second network node 112 operating in the wireless communications network 100.

[0075] The first wireless device 131 may have to monitor, as described later in Action 603, one or more WLISs transmitted by the first network node 111 in one or more monitoring occasions and according to one or more characteristics.

[0076] The information may indicate the one or more characteristics. The one or more characteristics may, for example, comprise a first number of monitoring occasions.

[0077] The one or more WLISs may be one or more low power wake-up signals (LP-WLIS).

[0078] The information may be configuration information, e.g., WUS or LWLIS configuration information.

[0079] The information may comprise at least one of first information and second information. The first information may indirectly indicate the one or more characteristics. The second information may directly indicate the one or more characteristics.

[0080] The one or more characteristics may comprise a first start of at least one monitoring occasion of the one or more monitoring occasions.

[0081] As mentioned earlier, the usage of “first”, “second”, “third” and / or “fourth” herein may be understood to be an arbitrary way to denote different elements or entities, and may be understood to not confer a cumulative or chronological character to the nouns they modify, unless otherwise noted, based on context.

[0082] Particularly, the “first” start may be understood to be one of several starts described herein. The first start may be understood to refer, particularly, to the start of at least one monitoring occasion (MO), of the one or more monitoring occasions, that the first wireless device 131 may be interested in determining, e.g., calculating.

[0083] UEs monitoring a PO may be divided into multiple UE subgroups. In some examples, the first information may comprise a second number of subgroups, e.g., N-sg, e.g., of wireless devices 130, in a paging occasion (PO). The PO may be associated with / corresponding to the one or more monitoring occasions.

[0084] In some embodiments, the first information, e.g., WUS or LWUS configuration information, may comprise one or more of the following options.

[0085] According to one option, the first information may comprise one or more thresholds, e.g., sg-thresh1 , sg-thresh2. The one or more thresholds may be used herein in some calculations of the one or more characteristics, as described later in relation to some examples. According to another option, the first information may comprise a third number of transmitted Synchronization Signal Blocks (SSBs) or beams. As explained earlier, in order to improve the coverage and interference mitigation, a gNB such as the first network node 111, may transmit a unified WUS with beam sweeping, which may be detected by OOK WUR and OFDM WUR. Different beams may refer to different spatial filter settings, e.g., Spatial Reception parameters, applied by the multi-antenna system of gNB or UE for transmitting or receiving LP- WUS. For example, if Beam X corresponds to SSB X and Beam Y corresponds to SSB Y, then the first wireless device 131 , e.g., a UE, may use the same Spatial Reception parameters it may use for receiving SSB X for LP-WUS / LP-SS reception using Beam X. Similarly, it may use the same Spatial Reception parameters it may use for receiving SSB Y for LP-WUS / LP-SS reception using Beam Y.

The second offset, which may be referred to herein as e.g., Tdur, may be, between the third start of the LO and the first start of the at least one monitoring occasion of the one or more monitoring occasions; the second offset may be at least based on a first duration of at least one other monitoring occasion, which may be referred to herein as a ’’first” monitoring occasion, prior to the at least one monitoring occasion of the one or more monitoring occasions.

[0089] The second offset may include a second duration of monitoring occasions in the LO that may be prior to the at least one monitoring occasion of the one or more monitoring occasions.

[0090] In some one or more additional options of the one or more options recited above, the first information, e.g., WUS or LWUS configuration information, may comprise one of more of the following: the second number of subgroups, e.g., N-sg, e.g., of wireless devices 130, in the PO, a length of the one or more monitoring occasions, and a duration of the one or more monitoring occasions.

[0091] In some embodiments, at least one monitoring occasion of the one or more monitoring occasions may be associated to a Kth transmitted Synchronization Signal Block (SSB). The Kth transmitted SSB may belong to a set of transmitted SSBs. K may be an integer index K=1 ,2, ... S. S may be a fifth number of transmitted SSBs in the set of transmitted SSBs. The fifth number may be the same, or different, than the third number.

The MO duration may be understood to be an example of the duration of the one or more monitoring occasions.

[0094] The one or more characteristics may further comprise one or more of the following. According to one option, the one or more characteristics may further comprise the first number of monitoring occasions. According to another option, the one or more characteristics may further comprise an arrangement of the one or more monitoring occasions, e.g., in a low power wake-up signal occasion, such as in the LO associated with the one or more monitoring occasions. The arrangement may be understood to refer to an organization of the one or more MOs, e.g., a specific arrangement pattern of LP-WLIS MOs in the LO. According to another option, the one or more characteristics may further comprise a format for detection of the one or more WUSs.

[0095] In some embodiments, one or more of the following may apply. According to one option, the one or more WUSs may be one or more low power wake-up signals (LP-WUS), and according to another option, the format for detection of the one or more WUSs may be one of: On / Off keying (OOK), and Orthogonal Frequency Division Multiplexing (OFDM).

[0101] The second number of subgroups, e.g., N-sg, may be configured by higher layers, that is, by higher layer signalling, e.g., by the first network node 111.

[0102] In some embodiments, the second offset may be determined by the first wireless device 131 based on one or more of the following options. According to one option, the second offset may be determined by the first wireless device 131 based on the MO duration used by the first wireless device 131 for monitoring in Action 603 the one or more WLISs in the one or more monitoring occasions. The MO duration may be determined from higher later signalling. According to another option, the second offset may be determined by the first wireless device 131 based on a sixth number of monitoring occasions from the third start of the LO associated with the one or more monitoring occasions until and including the monitoring occasions that correspond to a K-1th transmitted SSB, the K-1th transmitted SSB belonging to the set of transmitted SSBs.

[0106] According to another option, the higher layer signaling may include a Radio Resource Control (RRC) parameter indicating a seventh number of radio frames between the third start of the LO and the associated PO.

[0107] In some examples, e.g., of a first group of examples, the one or more characteristics may comprise the first number of monitoring occasions. In some of such examples, the determining in this Action 602 of the one or more characteristics may comprise determining the first number of monitoring occasions based on the second number of subgroups of wireless devices 130 in the PO in relation to the one or more thresholds.

Such examples may be combined with any of the examples described under the heading Second group of examples.

[0109] In some examples, e.g., of a third group of examples, the one or more characteristics may comprise the first start of the at least one of the one or more monitoring occasions. In some of such examples, the determining in this Action 602 of the one or more characteristics may comprise determining the first start of the at least one of the one or more monitoring occasions corresponding to one of the transmitted SSBs or beams. Such examples may be combined with any of the examples described under the heading Third group of examples.

[0114] Action 603

[0115] In this Action 603, first wireless device 131 monitors one or more WLISs.

[0116] The one or more WLISs are transmitted by the first network node 111.

[0117] The monitoring in this Action 603 is in the one or more monitoring occasions. The monitoring in this Action 603 is in the one or more monitoring occasions and according to the one or more characteristics. As stated earlier, the one or more characteristics comprise the first start of the at least one monitoring occasion of the one or more monitoring occasions. The one or more characteristics are determined by the first wireless device 131 based on: i) the first offset between the second start of the paging frame associated with the PO associated with the one or more monitoring occasions and the third start of the LO associated with the one or more monitoring occasions, and ii) the second offset between the third start of the LO and the first start of the at least one monitoring occasion of the one or more monitoring occasions. The second offset is at least based on the first duration of at least one other monitoring occasion prior to the at least one monitoring occasion of the one or more monitoring occasions.

[0118] In some examples, one or more of the following may apply: the one or more WLISs may be one or more low power wake-up signals (LP-WLIS), and the format for detection of the one or more WLISs may be one of: OOK, and OFDM.

[0119] Monitoring of LP-WUS

[0120] Monitoring of LP-WUS may generally imply actions performed by the first wireless device 131 to detect or decode an LP-WUS. The first wireless device 131 may attempt to detect LP- WUS in a set of time / frequency resources. The time resources may be OFDM symbols, and the frequency resources may be physical resource blocks (PRBs) or subcarriers within the PRBs. The time resources may also be referred to in terms of LP-WUS monitoring occasions (MOs). The first wireless device 131 may typically determine LP-WUS information upon successful detection / decoding of LP-WUS. Based on LP-WUS information, the first wireless device 131 may determine whether to monitor paging PDCCH in one or more subsequent paging occasions (POs) associated with the detected LP-WUS. The first wireless device 131 may typically determine whether it is being paged or not based on information scheduled by a paging PDCCH.

[0121] As stated earlier, UEs monitoring a PO may be divided into multiple UE subgroups. For example, LP-WUS information may be wake-up indication for one or more subgroups that a UE may belong to. If the first wireless device 131 determines that LP-WUS information indicates ‘wake up’ for its subgroup(s), it may monitor one or more POs associated with the LP-WUS and if LP-WUS information does not indicate ‘wake up’ for its subgroup(s), it may skip monitoring the associated one or more POs. This may enable energy efficient UE operation.

[0122] Indication of ‘wake-up’ via LP-WUS information may for example be successful decoding of one or more code-points decoded from LP-WUS or successful decoding that one or more bit positions in a bitmap decoded from LP-WUS are set to a specific bit-value, e.g., T. The one or more code-points may be associated to the one or more subgroups that the first wireless device 131 may belong to, e.g., ‘code-point based’ LP-WUS information. The one or more bit positions in the bitmap may be associated to the one or more subgroups that the first wireless device 131 may belong to, e.g., ‘bitmap based’ LP-WUS information.

[0123] LP-WUS occasions (LOs) may be defined for LP-WUS monitoring. Each LO may have one or more LP-WUS monitoring occasions (MOs) where first wireless device 131 may monitor for LP-WUS transmission in each of the LP-WUS MOs. Different LP-WUS MOs may correspond to different beams in multi-beam operation. The first wireless device 131 may monitor LOs with a configured periodicity. The MOs may typically comprise time resources, such as OFDM symbols or slots or subframes or frames as defined for NR. In an LP-WLIS MO, the first wireless device 131 may attempt to detect LP-WLIS to decode LP-WLIS information. The LP-WLIS information may be code-point based or bitmap based as described above. An LP-WLIS MO may comprise a set of OFDM symbols. LP-WLIS information may be encoded and transmitted, e.g., by the first network node 111 , e.g., a gNB, or received, e.g., by the first wireless device 131 , on the set of OFDM symbols. For example, LP-WLIS information may be encoded and transmitted, e.g., by the first network node 111 , e.g., a gNB, or received, e.g., by the first wireless device 131 , on one or more repetitions of resource allocation units (RAlls), where each RAU may comprise a set of OFDM symbols, e.g., according to the procedures described in an unpublished document.

[0124] For the below examples, the signaling indicating the second number of subgroups (N_sg) may for example comprise RRC parameter(s) sent in a system information block (SIB). The second number of subgroups N_sg may be a total number of subgroups for both core network (ON) assigned subgrouping, if any, and UE_ID based subgrouping, if any, in a PO. Alternately, N_sg may be number of subgroups for UE_ID based subgrouping in a PO.

[0125] Higher layer signaling in the below examples may refer to RRC signaling which may include broadcast signaling such as SIB.

[0126] First group of Examples

[0127] In an example of the first group of examples, the first wireless device 131 may receive signaling indicating the second number of subgroups (N_sg). The first wireless device 131 may monitor for LP-WLIS in one or more MOs where the number of MOs (N_mos) monitored for LP- WUS by the first wireless device 131 may be based on the second number of subgroups.

[0128] In one example, the first wireless device 131 may monitor for LP-WLIS in only one MO if the number of subgroups is smaller than or equal to a first threshold (sg-thresh1) and may monitor for LP-WLIS in multiple MOs if the number of subgroups is larger than the first threshold. The first threshold may be a predefined value or may be determined by the first wireless device 131 based on higher layer signaling. For example, sg-thresh1=8 and if N_sg is indicated to be larger than 8, the first wireless device 131 may monitor multiple MOs, e.g., K1_MOs=2, 4 MOs where K1_MOs may be predefined or determined from higher layer signalling; otherwise, the first wireless device 131 may monitor only one MO.

[0129] In another example, N_mos may be as shown in Table 1 below, where sg-thresh1 and sg- thresh2 may be threshold values for N_sg which may be predefined or configured or may be determined by the first wireless device 131 based on higher layer signaling. Figure 8 illustrates this example.

[0130] Figure 8 is a schematic diagram illustrating LP-WLIS MOs associated with a PO.

[0131] Table 1.

[0132] In another example, the number of MOs (N_mos) monitored for LP-WLIS by the first wireless device 131 may be based on higher layer signaling indicating a number of monitoring occasions, where the candidate values of higher layer signaling may be restricted such that the first wireless device 131 may monitor for LP-WLIS in only one MO if N_sg <= sg-thresh1 and may monitor LP-WLIS in multiple MOs if N_sg > sg-thresh1.

[0133] In another example, the number of MOs (N_mos) monitored for LP-WLIS by the first wireless device 131 may be based on higher layer signaling indicating a number, e.g., the first number, of monitoring occasions, where the candidate values of higher layer signaling may be restricted such that the first wireless device 131 may monitor for LP-WLIS in only one MO if N_sg <= sg-thresh1 and may monitor LP-WLIS in one or multiple MOs if N_sg > sg-thresh1.

[0134] Enabling LP-WLIS reception by UEs in several MOs may improve latency performance, e.g., gNB may have more opportunities to send WUS in LO without postponing to next LO, and may increase gNB flexibility. However, WUR decoding complexity and power consumption may increase with monitoring in multiple MOs. The approaches in this section may enable an efficient trade-off by increasing the WUS MOs monitored by the LP-WUR only for certain cases. When the second number of subgroups increases, the probability for the first network node 111, e.g., the gNB, to send WUS for more than one subgroup may increase. Increasing the LP-WUS MOs based on number of subgroups may provide an efficient mechanism to achieve such a tradeoff.

[0135] Second group of Examples

[0136] In an example of the second group of examples, the first wireless device 131 may receive signaling indicating the second number of subgroups (N_sg). The first wireless device 131 may monitor for LP-WUS in an MO where the start of the MO, e.g., the first start, may be based on the second number of subgroups (N_sg) and a subgroup index (ue-sgid) of a subgroup that the first wireless device 131 may belong to. In some cases, the start of the MO, e.g., the first start, may be based on one of N_sg or ue-sgid.

[0137] In one example, the first wireless device 131 may determine that the first start of the MO is at a first location with respect to the associated PO, e.g., a first OFDM symbol position or a slot or frame, if the second number of subgroups (N_sg) is smaller than or equal to a first threshold, e.g., sg-thresh21 , and if the second number of subgroups is larger than the first threshold, the first wireless device 131 may select the first start of the MO to be either the first location or a second location, e.g., a second OFDM symbol position or a slot or frame, based on the subgroup index (ue-sgid) of the subgroup that the first wireless device 131 may belong to. The first threshold may be a predefined value or may be determined by the first wireless device 131 based on higher layer signaling.

[0138] If N_sg > sg-thresh21, in one example, the first wireless device 131 may use a mathematical function, e.g., a modulo function, that may take ue-sgid as an input to select the first start of the MO between the first location and the second location. For example, sg- thresh21=16 and if N_sg>16 is indicated, the first wireless device 131 may select the first location if its ue-sgid is an even number and the second location if its us-sgid is an odd number. Figure 9 illustrates this example, where L1 is the first location and L2 is the second location.

[0139] Figure 9 is a schematic diagram illustrating a start location of a LP-WLIS MO associated with a PO.

[0140] In another example, the first wireless device 131 may use a sub-group index threshold to select the first start of the MO to be either the first location or the second location. For example, if Nsg > sg-thresh21 is indicated, the first wireless device 131 may select the second location if ue-sgid is greater than or equal to ceil(Nsg / 2)-1 and may select the first location otherwise.

[0141] The first wireless device 131 may monitor one or more MOs associated to a PO. The first start of the MO discussed in this example may refer to the start of the first MO of the one or more MOs associated to the PO.

[0142] In another example, the LP-WLIS may provide bitmap-based LP-WLIS information. For such cases, the association between bit positions in a bitmap and ue-sgid may be based on the starting position of the MO in which the LP-WLIS may be monitored.

[0143] For an example, where N_sg=16, UEs may be assigned a ue-sgid between 0 and Nsg- 1=15. UEs with ue-sgid 0,1, 2, 3, 4, 5, 6, 7, that is, ue-sgid <= ceil(Nsg / 2)-1, may select the first start of MO to be the first location and UEs with ue-sgid 8,9,10,11,12,13,14,15, that is, ue-sgid > ceil(Nsg / 2)-1, may select the first start of MO to be the second location. Then bitmap based LP- WUS information may be such that, when the first start of MO is at the first location, the first bit position of the bitmap may correspond to ue-sgid 0, second bit position of the bitmap may correspond to ue-sgid 1 and so on and the last bit position of the bitmap may correspond to ue- sgid 7; while when the first start of MO is at the second location, the first bit position of the bitmap may correspond to ue-sgid 8, second bit position of the bitmap corresponds to ue-sgid 9 and so on and the last bit position of the bitmap may correspond to ue-sgid 15.

[0144] Having separate LP WUS MOs based on ue-sgid may reduce WUR complexity, e.g., the first wireless device 131 may have to monitor a shorter bitmap in its MO. However, it may also increase network (NW) overhead as the first network node 111 may have to transmit WUS in multiple MOs. Enabling additional MO starting locations only when N_sg is large may enable efficient trade-off between WUR complexity and NW overhead.

[0145] Third group of Examples

[0146] In an example of the third group of examples, the first wireless device 131 may monitor in one or more LP-WLIS MOs associated with a PO.

[0147] The PO may be a set of 'S*X ' consecutive PDCCH monitoring occasions where 'S' may be the number of actual transmitted SSBs and X may be the number of PDCCH monitoring occasions per SSB in the PO. S may be determined from a higher layer parameter indicating SSB positions in an SSB burst, e.g., ssb-PositionsInBurst in SIB1. X may be determined from another higher layer parameter, e.g., nrofPDCCH-MonitoringOccasionPerSSB-InPO, and may have a default value 1 if the parameter is not configured. The [x*S+K]th PDCCH monitoring occasion for paging in the PO may correspond to the Kth transmitted SSB, where x=0,1 ,... ,X-1 , K=1 ,2,... ,S. The S actual transmitted SSBs may each correspond to different beams and the [x*S+K]th PDCCH monitoring occasion for paging in the PO may correspond to the Kth beam of S beams.

[0148] The one or more LP-WLIS MOs associated with the PO may be S*Y LP-WLIS MOs. The S*Y LP-WLIS MOs may be considered to belong to a LP-WLIS occasion (LO) associated with the PO. The LP-WLIS MOs in the LO may be monitored such that corresponding to each transmitted SSB, or beam, of the S transmitted SSBs, LP-WLIS in Y MOs may be monitored. This may imply each set of Y MOs of the S*Y MOs may correspond to one transmitted SSB, or beam, of the S transmitted SSBs, or beams. In some cases, S may also be determined from a number of beams used for transmitting a low-power synchronization signal (LP-SS).

[0149] A [y*S+K]th LP-WLIS MO of the S*Y MOs may correspond to the Kth transmitted SSB, where y=0,1 ,... ,Y-1 , K=1 ,2,... ,S. Y may be a number greater than equal to 1.

[0150] The first wireless device 131 may determine the starting location of [y*S+K]th LP-WLIS MO corresponding to a PDCCH monitoring occasion that may correspond to Kth transmitted SSB in the PO based on the following: a) the first offset, e.g., Toffset, between the second start of the PO and the associated LO with S*Y MOs. The first offset may be a time offset. The first offset may comprise radio frames, subframes, slots or OFDM symbols. The first offset may be determined by the first wireless device 131 based on higher layer signaling. The higher layer signaling may include an RRC parameter indicating a number radio frames between the start of the LO and the associated PO, b) the second offset (Tdur) between the start of the LO and the start of the [y*S+K]th LP-WUS MO. The second offset may be a time offset. The second offset may comprise subframes, slots or OFDM symbols.

[0151] The second offset may include the time duration from the first LP-WUS MO of the LO until (and including) the [y*S+K]-1th LP-WUS MO.

[0152] The second offset may be determined by the first wireless device 131 based on one or more of the following: i) MO duration, which may be a configured number of OFDM symbols or slots and determined from higher layer signalling; ii) number of MOs from the first LP-WLIS MO of the LO until (and including) the [y*S+K]-1th LP-WLIS MO; iii) Relative SSB position of the Kth transmitted SSB in an SSB burst; iv) UL slots or other time domain resources, e.g., OFDM symbols, not used for LP-WLIS transmission between the first LP-WLIS MO of the LO and the [y*S+K]th LP-WUS MO.

[0153] In an example, Y may be predefined or determined by the first wireless device 131 via higher layer signaling. In an example, Y may be determined by the first wireless device 131 using the procedures described for determining N_mos, that is, number of monitoring occasions for LP-WUS, in the examples of the First group of examples.

[0154] In an example, the starting location of [y*S+K]th LP-WUS MO may be determined by the first wireless device 131 by additionally using the procedures described for determining starting MO position in the examples of the Second group of examples.

[0155] This may enable efficient beam formed LP-WUS transmissions, especially for the case with enhanced coverage for LP-WUS, for example, where LP-WUS transmissions may span one or multiple slots.

[0156] More generally, in an example, the first wireless device 131 may acquire higher layer signaling comprising: i) LP-WUS configuration information, containing one or more of the following: a parameter indicating the second number of subgroups associated with a PO, a parameter indicating the first offset between the second start of a paging occasion / frame and the third start of a LP-WUS occasion, one or more parameters indicating the length / duration of a LP-WUS monitoring occasion, a parameter to identify the number of LP-WUS monitoring occasions associated with an SSB of the SSB burst; ii) information about the number of transmitted SSBs in a SSB burst. The first wireless device 131 may determine one or more LP- WUS monitoring occasion(s) associated with PO PDCCH monitoring occasion corresponding to a K-th transmitted SSB of an SSB burst based on the following: the first offset, the second offset (Tdur) between the third start of the LO and the start of the [y*S+K]th LP-WUS MO. The first wireless device 131 may then monitor for the LP-WUS in at least one or more LP-WUS monitoring occasion(s) associated with the K-th SSB of the transmitted SSB burst.

[0157] Figure 10 is a schematic diagram illustrating a start location of a LP-WUS MO for a multibeam scenario. The first start, the second start and the third start, as used herein, as well as the one or more MOs are indicated in the example of Figure 10.

[0158] Fourth group of Examples

[0159] In an example of the fourth group of examples, the first wireless device 131 may monitor one or more LP-WUS MOs associated with a PO where the first start of the MO may be based at least on a subgroup index (ue-sgid) of a subgroup that the first wireless device 131 may belong to. The PO may be a set of 'S*X ' consecutive PDCCH monitoring occasions where 'S' may be the number of actual transmitted SSBs and X may be the number of PDCCH monitoring occasions per SSB in the PO. Additional details of the PO may be according to the description in the examples of the third group of examples.

[0160] The one more LP-WLIS MOs associated with the PO may be S*(Nseg*Y) LP-WLIS MOs. Nseg may be understood as a parameter for organizing MOs. How to use the parameter is explained below. The S*(Nseg*Y) LP-WLIS MOs may be considered to belong to a LP-WLIS occasion (LO) associated with the PO. The LP-WLIS MOs in the LO may be monitored such that corresponding to each transmitted SSB, or beam, of the S transmitted SSBs, LP-WLIS in Y MOs may be monitored. This may imply that each set ofY MOs of the S*(Nseg*Y) MOs may correspond to one transmitted SSB of the S transmitted SSBs, or beams. In some cases, S may also be determined from a number of beams used for transmitting a low-power synchronization signal (LP-SS).

[0161] Nseg may be an integer number. Nseg may be determined by the first wireless device 131 based on higher layer signaling.

[0162] In one example, Nseg may be configured by a higher layer parameter.

[0163] In another example, Nseg may be determined based on the second number of subgroups (N_sg). E.g., Nseg=1 if N_sg<= sg-thresh21 and a number greater than one otherwise.

[0164] In another example, the LP-WLIS may provide bitmap-based LP-WLIS information and Nseg may be determined based on a bitmap length determined by the first wireless device 131. For example, if length of bitmap is B bits then Nseg = ceil (N_sg / B).

[0165] In some cases, the first wireless device 131 may be considered to select an LP-WLIS MO from Nseg candidate LP WUS MOs where the selection may be based on ue-sgid.

[0166] Operating the system with Nseg > 1 may help reduce WUR complexity, e.g., by reducing decoding overhead to detect the LP-WLIS information from a bitmap of length B<N_sg bits as opposed to a long bitmap of length N_sg bits. This may be especially relevant when N_sg is large e.g., >4 bits, in which case the bitmap length may be capped to 4 bits.

[0167] A [y*Nseg*S+ J + (K-1)*Nseg]th LP-WLIS MO of the LO may correspond to the Kth transmitted SSB, where y=0, 1 , ... ,Y-1 and Y may be a number greater than or equal to 1. K=1 ,2,... ,S. J=1 , 2,... Nseg where Nseg may be a number greater than or equal to 1.

[0168] Figure 11 is a schematic diagram illustrating ordering of LP-WLIS MOs in LO for a multibeam scenario. Figure 11 illustrates a non-limiting example of ordering of LP-WUS MOs in LO for a multibeam scenario for a case when Nseg=2. In the figure, the MOs containing ‘SEGT illustrate MOs with J=1 and MOs containing ‘SEG2’ illustrate MOs with J=2. The MOs containing ‘beamK’ illustrate the one or more LP-WUS MOs corresponding to a PDCCH monitoring occasion that may correspond to Kth transmitted SSB in the PO. The first wireless device 131 may determine the starting location of [y*Nseg*S+ J + (K- 1)*Nseg]th LP-WLIS MO corresponding to a PDCCH monitoring occasion that may correspond to Kth transmitted SSB in the PO based on the following: a) the first offset (Toffset) between the second start of the PO and the associated LO; The first offset may be a time offset; The first offset may comprise radio frames, subframes, slots or OFDM symbols; The first offset may be determined by the first wireless device 131 based on higher layer signaling; The higher layer signaling may include a RRC parameter indicating a number radio frames between the third start of the LO and the associated PO; b) the second offset (Tdur) between the third start of the LO and the start of the of [y*Nseg*S+ J + (K-1)*Nseg]th LP-WUS MO. The second offset may be a time offset. The second offset may comprise subframes, slots or OFDM symbols.

[0169] The second offset may include the time duration from the first LP-WUS MO of the LO until (and including) the of [y*Nseg*S+ J + (K-1)*Nseg] -1th LP-WUS MO. The second offset may be determined by the first wireless device 131 based on one or more of the following: i) subgroup index (ue-sgid) of a subgroup that the first wireless device 131 may belong to; For example, the first wireless device 131 may select the value of J from 1 ,2,... Nseg based on its ue-sgid; For example, the first wireless device 131 may select the value of J based on one or more of Nseg, N_sg and ue-sgid; For example, J=MOD (ue_sgid, Nseg) where MOD() may be the modulo function; ii) MO duration, which may be a configured number of OFDM symbols or slots and determined from higher layer signaling; iii) number of MOs from the first LP-WUS MO of the LO until, and including, the [y*Nseg*S+ J + (K-1)*Nseg] -1th LP-WUS MO; iv) relative SSB position of the Kth transmitted SSB in a SSB burst; v) UL slots or other time domain resources, e.g., OFDM symbols, not used for LP-WUS transmission between the first LP-WUS MO of the LO and the [y*Nseg*S+ J + (K-1)*Nseg]th LP-WUS MO.

[0170] In an example, Y may be predefined or determined by the first wireless device 131 via higher layer signaling. In an example, Y may be determined by the first wireless device 131 using the procedures described for determining N_mos, that is, number of monitoring occasions for LP- WUS, in the examples of the First group of examples.

[0171] In an example, the starting location of [y*Nseg*S+ J + (K-1)*Nseg]th LP-WUS MO may be determined by the first wireless device 131 by additionally using the procedures described for determining the starting MO position in the examples of the Second group of examples.

[0172] These approaches may be understood to enable efficient beam formed LP-WUS transmissions, especially for the case with enhanced coverage for LP-WUS, for example, where LP-WUS transmissions may span one or multiple slots.

[0173] Fifth group of Examples

[0174] In an example of the fifth group of examples, the first wireless device 131 may monitor one or more LP-WUS MOs associated with a PO, where the starting position of the one or more MO(s) may be determined by the first wireless device 131 based on a waveform type of LP-WUS used by the UE for LP-WLIS monitoring. The waveform type of LP-WLIS may be, for example, OOK- based LP-WUS or OFDM-based LP-WUS.

[0175] Figure 12 is a schematic diagram illustrating an arrangement of LP-WUS MOs in LO for different LP-WUS waveform types. Figure 12 shows a non-limiting example arrangement of LP- WUS MOs in LO for OFDM-based and OOK-based LP-WUS.

[0176] The first wireless device 131 may additionally use the procedures described in the examples of the Third group of examples or the examples of the Fourth group of examples above to determine the starting position of the one or more MO(s).

[0177] In one example, the first wireless device 131 may use procedures described in the examples of the Fourth group of examples and may determine the starting position of [y*Nseg*S+ J + (K- 1)*Nseg]th LP-WUS MO corresponding to a PDCCH monitoring occasion that may correspond to Kth transmitted SSB in the PO based on the following: i) the first offset (Toffset) between the second start of the PO and the associated LO as described in the examples of the Third group of examples, e.g., assuming Nseg=1 , J=0, or the examples of the Fourth group of examples; The Toffset value may be the same for both OOK-based and OFDM-based LP-WUS monitoring; For example, a common RRC parameter indicating a number of radio frames between the start of the LO and the associated PO may be provided by higher layers for both OOK-based and OFDMbased LP-WUS monitoring and the first wireless device 131 may use that parameter to determine Toffset; ii) the second offset (Tdur) between the third start of the LO and the start of the of [y*Nseg*S+ J + (K-1)*Nseg]th LP-WUS MO. For determining Tdur, the first wireless device 131 may use the procedures described in the examples of the Third group of examples, e.g., assuming Nseg=1 , J=0, or the examples of the Fourth group of examples, with following additional aspects. The first wireless device 131 may determine Y additionally based on waveform-type used for LP- WUS monitoring. For example, based on separate higher layer parameters for OOK-based and OFDM-based LP-WUS monitoring.

[0178] The first wireless device 131 may determine Nseg additionally based on waveform-type used for LP-WUS monitoring. For example, based on separate higher layer parameters for OOK- based and OFDM-based LP-WUS monitoring. For example, based on a waveform-type specific sg-thresh21 value.

[0179] The first wireless device 131 may determine MO duration additionally based on waveformtype used for LP-WUS monitoring.

[0180] Sixth group of Examples

[0181] In an example of the sixth group of examples, the first wireless device 131 may receive signaling indicating the second number of subgroups (N_sg) and may monitor LP WUS in one or more LP-WUS MOs where the format of LP-WUS information may be based on the second number of subgroups. For example, if N_sg <= threshl , the first wireless device 131 may monitor the LP WUS MOs to detect LP WUS information with a bitmap format, e.g., to detect ‘bitmap based’ LP-WLIS information as discussed above. If N_sg > threshl , the first wireless device 131 may monitor the LP WUS MOs to detect LP-WLIS information with a format other than bitmap, e.g., ‘code-point’ based LP-WLIS information as discussed above. ‘threshT may be understood to be a number greater than 1 and may be a predefined integer value. For example, 8. The first wireless device 131 monitoring of LP WUS MOs may be additionally according one or more of the several examples discussed above.

[0182] To keep a good balance between LP-WUS payload size and flexibility of addressing multiple UE subgroups, an appropriate choice between bitmap and codepoint approaches may be required. When monitoring for LP-WUS in an MO, the first wireless device 131 may look for codepoint(s) or bitmap carried in the LP-WUS payload and may trigger a subsequent paging monitoring if its subgroup is indicated by the codepoint(s) or in the bitmap. More detailed analysis on codepoint vs. bitmap for LP-WUS transmission is provided in [9], Whether the codepoint or bitmap is used may be configured by the network.

[0183] If a codepoint based approach is used for UE subgroup indication, e.g., option 2 or option 3 from RAN1#117 agreement (the agreement states: “For RRC idle / inactive state, down-select among the following options for at least indicating subgroup information using LP-WUS: A) Option 1: A LP-WUS indicates a bitmap with each bit corresponding to one subgroup ofN subgroups for part of, one or more PO(s), e.g., N is 8~16, 24; Number of information bits for a LP-WUS is at least N, single LP-WUS to wake up one or more subgroups, b) Option 2 A LP-WUS indicates a codepoint value corresponding to one or more subgroup(s) from N subgroups for part of, one or more POs, e.g., N is 8-256; Number of information bits fora LP-WUS is at least ceil (log2(X1)), where X1 is the number of codepoints indicating one or more subgroups. X1 is reported by companies, X1 could be smaller, equal to or larger than N, c) Option 3: A LP-WUS indicates multiple codepoint values with each corresponding to one or more subgroup(s) from N subgroups for part of, one or more POs, e.g., N is 8-256; Number of information bits for a LP-WUS is at least K*ceil (log2(X2)), where X2 is the number of codepoints indicating one or more subgroups. X2 is reported by companies, X2 could be smaller, equal to or larger than N; K is the number of multiple codepoint values in a LP-WUS where K is larger than 7”), LP-WUS monitoring on multiple MOs (K>1 MOs) by the first wireless device 131 may be needed especially to cover scenarios with higher paging load or large number of subgroups [9], Having a large K however may increase WUR power consumption.

[0184] If bitmap-based approach, option 1 from RAN1#117 agreement, is used then UE monitoring of multiple MOs may not be needed as wake-up indication for several UE subgroups may be sent in one MO using the bitmap. However, if the number of subgroups is large, long bitmaps may result in large WUS payload, e.g., 32 bit bitmap for 32 subgroups, which may be understood to increase WUS overhead and impact coverage [9], It may also impact UE complexity depending on the type of decoding used by the first wireless device 131. To avoid this, the bitmaps may have to be segmented to cover smaller subsets of UEs, e.g., two bitmaps each covering half the UE subgroups. This may be understood to effectively segment the MOs, that is., UEs may need to monitor only the MOs in which the smaller bitmap corresponding to their subgroup may be expected. Even for codepoint based approach, such segmentation may be needed to reduce the MOs monitored by each UE, e.g., UE subgroups split into two halves with each half monitoring two MOs instead of all UEs monitoring four MOs.

[0185] In summary, segmentation of MOs in a LO, based on UE subgroup index, may be needed if LP-WUS operation with higher paging load and large number of subgroups per PO is to be supported.

[0186] Figure 13 is a schematic diagram depicting LP-WUS monitoring for the multi-beam scenario with two UE subgroup segments. Figure 13 illustrates segmented MOs for multibeam scenario with N beams, and UEs split into two segments Seg1 and Seg2 with each UE monitoring two MOs (MO1 , MO2).

[0187] Action 604

[0188] In this Action 604, first wireless device 131 may monitor a channel. The channel may be, e.g., a Physical Downlink Control Channel (PDCCH).

[0189] The monitoring in this Action 604 may be, e.g., via the first link 141.

[0190] The monitoring in this Action 604 may be based on whether or not the one or more WUSs may have been detected by the monitoring 603 in the one or more monitoring occasions.

[0191] In some embodiments, the monitoring in this Action 604 of the PDCCH based on whether or not the one or more WUSs have been detected by the monitoring of Action 603 in the one or more monitoring occasions may further comprise monitoring a first PDCCH corresponding to the Kth transmitted SSB based on whether or not the one or more WUSs have been detected by the monitoring in Action 603 in the at least one monitoring occasion of one or more monitoring occasions corresponding to the Kth transmitted SSB.

[0192] In some of the second set of examples, the one or more characteristics may be derived from the second number of subgroups, e.g., N-sg, e.g., of wireless devices 130, in the paging occasion, PO, e.g., the second number of subgroups, e.g., N-sg, e.g., being configured by higher layers.

[0227] Several embodiments are comprised herein. It should be noted that the examples herein are not mutually exclusive. One or more embodiments may be combined, where applicable. All possible combinations are not described to simplify the description. 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. The detailed description of some of the following corresponds to the same references provided above, in relation to the actions described for the first wireless device 131 and will thus not be repeated here. For example, the information may be, e.g., WUS or LWLIS configuration information.

[0228] The first wireless device 131 is configured to perform the monitoring in Action 603, e.g., by means of a processing circuitry 1401 within the first wireless device 131 configured to, monitor the one or more WLISs configured to be transmitted by the first network node 111.

[0481] Further Extensions And Variations

[0482] Figure 18 shows an example of a communication system 1800 in accordance with some embodiments.

[0483] In the example, the communication system 1800, such as the wireless communications network 100, includes a telecommunication network 1802 that includes an access network 1804, such as a radio access network (RAN), and a core network 1806, which includes one or more core network nodes 1808, such as the network node 112, e.g., the second network node 112, in some examples. The access network 1804 includes one or more access network nodes, such as the network node 111 , e.g., the first network node 111 , in other examples, such as network nodes 1810a and 1810b (one or more of which may be generally referred to as network nodes 1810), 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 1802 includes one or more Open-RAN (ORAN) network nodes. An ORAN network node is a node in the telecommunication network 1802 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 1802, including one or more network nodes 1810 and / or core network nodes 1808.

[0484] 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 1810 facilitate direct or indirect connection of user equipment (UE), such as by connecting UEs 1812a, 1812b, 1812c, and 1812d (one or more of which may be generally referred to as UEs 1812) to the core network 1806 over one or more wireless connections. Any of the UEs 1812a, 1812b, 1812c, and 1812d are examples of the first wireless device 131.

[0485] 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 1800 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 1800 may include and / or interface with any type of communication, telecommunication, data, cellular, radio network, and / or other similar type of system.

[0486] The first wireless device 131 , exemplified in Figure 18 as the UEs 1812 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 network node 111 , e.g., the first network node 111 , exemplified in Figure 18 as network nodes 1810 and other communication devices. Similarly, the network nodes 1810 are arranged, capable, configured, and / or operable to communicate directly or indirectly with the UEs 1812 and / or with other network nodes or equipment in the telecommunication network 1802 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 1802.

[0487] In the depicted example, the core network 1806 connects the network nodes 1810 to one or more host computing systems, such as host 1816. 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 1806 includes one more core network nodes (e.g., core network node 1808) 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 1808. 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).

[0488] The host 1816 may be under the ownership or control of a service provider other than an operator or provider of the access network 1804 and / or the telecommunication network 1802. The host 1816 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.

[0489] As a whole, the communication system 1800 of Figure 18 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.

[0490] In some examples, the telecommunication network 1802 is a cellular network that implements 3GPP standardized features. Accordingly, the telecommunications network 1802 may support network slicing to provide different logical networks to different devices that are connected to the telecommunication network 1802. For example, the telecommunications network 1802 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.

[0491] In some examples, the UEs 1812 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 1804 on a predetermined schedule, when triggered by an internal or external event, or in response to requests from the access network 1804. 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).

[0492] In the example, the hub 1814 communicates with the access network 1804 to facilitate indirect communication between one or more UEs (e.g., UE 1812c and / or 1812d) and network nodes (e.g., network node 1810b). In some examples, the hub 1814 may be a controller, router, content source and analytics, or any of the other communication devices described herein regarding UEs. For example, the hub 1814 may be a broadband router enabling access to the core network 1806 for the UEs. As another example, the hub 1814 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 1810, or by executable code, script, process, or other instructions in the hub 1814. As another example, the hub 1814 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 1814 may be a content source. For example, for a UE that is a VR device, display, loudspeaker, or other media delivery device, the hub 1814 may retrieve VR assets, video, audio, or other media or data related to sensory information via a network node, which the hub 1814 then provides to the UE either directly, after performing local processing, and / or after adding additional local content. In still another example, the hub 1814 acts as a proxy server or orchestrator for the UEs, in particular if one or more of the UEs are low energy loT devices.

[0493] The hub 1814 may have a constant / persistent or intermittent connection to the network node 1810b. The hub 1814 may also allow for a different communication scheme and / or schedule between the hub 1814 and UEs (e.g., UE 1812c and / or 1812d), and between the hub 1814 and the core network 1806. In other examples, the hub 1814 is connected to the core network 1806 and / or one or more UEs via a wired connection. Moreover, the hub 1814 may be configured to connect to an M2M service provider over the access network 1804 and / or to another UE over a direct connection. In some scenarios, UEs may establish a wireless connection with the network nodes 1810 while still connected via the hub 1814 via a wired or wireless connection. In some embodiments, the hub 1814 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 1810b. In other embodiments, the hub 1814 may be a non-dedicated hub - that is, a device which is capable of operating to route communications between the UEs and network node 1810b, but which is additionally capable of operating as a communication start and / or end point for certain data channels.

[0494] Figure 19 shows a UE 1900 in accordance with some embodiments. The UE 1900 presents additional details of some embodiments of the UE 1812 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.

[0495] 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).

[0496] The UE 1900 includes processing circuitry 1902 that is operatively coupled via a bus 1904 to an input / output interface 1906, a power source 1908, a memory 1910, a communication interface 1912, and / or any other component, or any combination thereof. Certain UEs may utilize all or a subset of the components shown in Figure 19. 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.

[0497] The processing circuitry 1902 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 1910. The processing circuitry 1902 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 1902 may include multiple central processing units (CPUs).

[0498] In the example, the input / output interface 1906 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 1900. 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.

[0499] In some embodiments, the power source 1908 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 1908 may further include power circuitry for delivering power from the power source 1908 itself, and / or an external power source, to the various parts of the UE 1900 via input circuitry or an interface such as an electrical power cable. Delivering power may be, for example, for charging of the power source 1908. Power circuitry may perform any formatting, converting, or other modification to the power from the power source 1908 to make the power suitable for the respective components of the UE 1900 to which power is supplied.

[0500] The memory 1910 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 1910 includes one or more application programs 1914, such as an operating system, web browser application, a widget, gadget engine, or other application, and corresponding data 1916. The memory 1910 may store, for use by the UE 1900, any of a variety of various operating systems or combinations of operating systems.

[0501] The memory 1910 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 1910 may allow the UE 1900 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 1910, which may be or comprise a device-readable storage medium.

[0502] The processing circuitry 1902 may be configured to communicate with an access network or other network using the communication interface 1912. The communication interface 1912 may comprise one or more communication subsystems and may include or be communicatively coupled to an antenna 1922. The communication interface 1912 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 1918 and / or a receiver 1920 appropriate to provide network communications (e.g., optical, electrical, frequency allocations, and so forth). Moreover, the transmitter 1918 and receiver 1920 may be coupled to one or more antennas (e.g., antenna 1922) and may share circuit components, software or firmware, or alternatively be implemented separately. In the illustrated embodiment, communication functions of the communication interface 1912 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.

[0503] Regardless of the type of sensor, a UE may provide an output of data captured by its sensors, through its communication interface 1912, 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).

[0504] 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.

[0505] 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 1900 shown in Figure 19.

[0506] 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.

[0507] 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.

[0508] Figure 20 shows a network node 2000 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).

[0509] 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). 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).

[0510] The network node 2000 includes a processing circuitry 2002, a memory 2004, a communication interface 2006, and a power source 2008. The network node 2000 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 2000 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 2000 may be configured to support multiple radio access technologies (RATs). In such embodiments, some components may be duplicated (e.g., separate memory 2004 for different RATs) and some components may be reused (e.g., a same antenna 2010 may be shared by different RATs). The network node 2000 may also include multiple sets of the various illustrated components for different wireless technologies integrated into network node 2000, 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 2000.

[0511] The processing circuitry 2002 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 2000 components, such as the memory 2004, to provide network node 2000 functionality.

[0512] In some embodiments, the processing circuitry 2002 includes a system on a chip (SOC). In some embodiments, the processing circuitry 2002 includes one or more of radio frequency (RF) transceiver circuitry 2012 and baseband processing circuitry 2014. In some embodiments, the radio frequency (RF) transceiver circuitry 2012 and the baseband processing circuitry 2014 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 2012 and baseband processing circuitry 2014 may be on the same chip or set of chips, boards, or units. The memory 2004 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 2002. The memory 2004 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 2002 and utilized by the network node 2000. The memory 2004 may be used to store any calculations made by the processing circuitry 2002 and / or any data received via the communication interface 2006. In some embodiments, the processing circuitry 2002 and memory 2004 is integrated.

[0513] The communication interface 2006 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 2006 comprises port(s) / terminal(s) 2016 to send and receive data, for example to and from a network over a wired connection. The communication interface 2006 also includes radio front-end circuitry 2018 that may be coupled to, or in certain embodiments a part of, the antenna 2010. Radio front-end circuitry 2018 comprises filters 2020 and amplifiers 2022. The radio front-end circuitry 2018 may be connected to an antenna 2010 and processing circuitry 2002. The radio front-end circuitry may be configured to condition signals communicated between antenna 2010 and processing circuitry 2002. The radio front-end circuitry 2018 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 2018 may convert the digital data into a radio signal having the appropriate channel and bandwidth parameters using a combination of filters 2020 and / or amplifiers 2022.

The digital data may be passed to the processing circuitry 2002. In other embodiments, the communication interface may comprise different components and / or different combinations of components.

[0514] In certain alternative embodiments, the network node 2000 does not include separate radio front-end circuitry 2018, instead, the processing circuitry 2002 includes radio front-end circuitry and is connected to the antenna 2010. Similarly, in some embodiments, all or some of the RF transceiver circuitry 2012 is part of the communication interface 2006. In still other embodiments, the communication interface 2006 includes one or more ports or terminals 2016, the radio frontend circuitry 2018, and the RF transceiver circuitry 2012, as part of a radio unit (not shown), and the communication interface 2006 communicates with the baseband processing circuitry 2014, which is part of a digital unit (not shown).

[0515] The antenna 2010 may include one or more antennas, or antenna arrays, configured to send and / or receive wireless signals. The antenna 2010 may be coupled to the radio front-end circuitry 2018 and may be any type of antenna capable of transmitting and receiving data and / or signals wirelessly. In certain embodiments, the antenna 2010 is separate from the network node 2000 and connectable to the network node 2000 through an interface or port.

[0516] The antenna 2010, communication interface 2006, and / or the processing circuitry 2002 may be configured to perform any receiving operations and / or certain obtaining operations described herein as being performed by the network node.

[0518] Embodiments of the network node 2000 may include additional components beyond those shown in Figure 20 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 2000 may include user interface equipment to allow input of information into the network node 2000 and to allow output of information from the network node 2000. This may allow a user to perform diagnostic, maintenance, repair, and other administrative functions for the network node 2000. In some embodiments providing a core network node, such as core network node 108 of FIG. 18, some components, such as the radio front-end circuitry 2018 and the RF transceiver circuitry 2012 may be omitted. Figure 21 is a block diagram illustrating a virtualization environment 2100 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 2100 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 2100 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.

[0519] Applications 2102 (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.

[0520] Hardware 2104 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 2106 (also referred to as hypervisors or virtual machine monitors (VMMs)), provide VMs 2108a and 2108b (one or more of which may be generally referred to as VMs 2108), and / or perform any of the functions, features and / or benefits described in relation with some embodiments described herein. The virtualization layer 2106 may present a virtual operating platform that appears like networking hardware to the VMs 2108.

[0521] The VMs 2108 comprise virtual processing, virtual memory, virtual networking or interface and virtual storage, and may be run by a corresponding virtualization layer 2106. Different embodiments of the instance of a virtual appliance 2102 may be implemented on one or more of VMs 2108, 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. In the context of NFV, a VM 2108 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 2108, and that part of hardware 2104 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 2108 on top of the hardware 2104 and corresponds to the application 2102.

[0522] Hardware 2104 may be implemented in a standalone network node with generic or specific components. Hardware 2104 may implement some functions via virtualization. Alternatively, hardware 2104 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 2110, which, among others, oversees lifecycle management of applications 2102. In some embodiments, hardware 2104 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 2112 which may alternatively be used for communication between hardware nodes and radio units.

[0523] 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.

[0524] 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.
