METHODS, APPARATUS AND COMPUTER-READABLE MEDIA RELATED TO REPORTING CONFIGURATIONSTechnical field

[0001] Embodiments of the disclosure relate to wireless communication, and particularly to methods, apparatus and computer-readable media for configuring measurement reports in a wireless network.BackgroundL1 / L2 Triggered Mobility (LTM)

[0002] 5G NR defines L1 / L2 triggered mobility (LTM) to reduce the handover latency in the legacy L3 handover by leveraging lower layer signaling. LTM is specified as a lower layer mobility procedure in Rel-18 in which a network node (e.g., gNB) receives measurement report(s), sent by a user equipment (UE), using LI signaling. The LI -measurement reports are utilized by the network to make different mobility-related decisions such as the LTM cell switch execution to another target cell by sending an LTM cell switch MAC control element (MAC CE) command. The step-by-step process for LTM is shown in Figure 1, and summarized below:1. The UE sends Measurement report(s) for the measurements performed on one or more cells to the gNB. Based on the received measurement report(s), the gNB decides to configure one or more LTM candidate cell(s). This procedure is referred to as LTM preparation.2. The gNB transmits a radio resource control (RRC) Reconfiguration message to the UE including the LTM candidate configuration(s).3. The UE stores the LTM candidate configuration(s) and responds to gNB with an RRC Reconfiguration Complete message.4a. The UE may perform an early DL synchronization with the LTM candidate cell(s) before LTM cell switch execution. The DL pre-synchronization is performed upon reception of a “Candidate Cell TCI States Activation / Deactivation MAC CE” by the UE for the transmission configuration indication (TCI) states in the configured LTM candidate cell(s). Since the DL synchronization is already acquired before the LTM cell switch, the UE is not required to wait for performing synchronization signal block (SSB) reference signal (RS) measurements after moving to the target cell which consequently reduces the mobility interruption.4b. The UE may also perform uplink (UL) pre-synchronization with the LTM candidate cell(s) if it receives the physical downlink control channel (PDCCH) order for early timing advance (TA) acquisition for those candidate cells. This means that the delay occurring in the random-access procedure after the baseline L3-moblity can be reduced from the overall mobility interruption in LTM.5. The UE performs LI measurements on the configured LTM candidate cell(s) and transmits LI measurement reports to the gNB. LI measurement should be performed for the LTM candidate cell(s) which were configured in step 2.6. The gNB decides to execute cell switch to a candidate target cell and transmits a MAC CE triggering cell switch by including the candidate configuration index of the LTM target cell. The UE switches to the target cell and applies the LTM candidate configuration indicated by candidate configuration index.7. The UE performs the random-access procedure towards the target cell if UE does not have valid TA of the target cell. Otherwise, if the UE receives a valid TA value in LTM cell switch command using early TA acquisition method in step 4b, the UE is not required to perform random-access. Moreover, if the target cell TCI state, which is included in the LTM Cell Switch MAC CE, is different from the TCI state activated in early DL synchronization, the UE may experience some delay in synchronization with the new TCI.8. The UE completes the LTM cell switch procedure by sending RRC Reconfiguration Complete message to target cell. If the UE has performed a random-access procedure in step 7, the UE considers that LTM cell switch execution is successfully completed when the random-access procedure is successfully completed. For RACH-less LTM, the UE considers that LTM cell switch execution is successfully completed when the UE determines that the network has successfully received its first UL data [1], Figure 1 depicts the overall procedure for LTM.LTM Measurement Report Scheduling in Rel-18

[0003] Rel-18 LTM defines four different types of measurement reporting related to the LTM procedures (e.g., early synchronization, LTM cell switch) provided in LTM reporting configuration. In Rel-18 LTM, periodic reporting on physical uplink control channel (PUCCH), semi-persistent reporting on PUCCH, semi-persistent reporting on physical uplink shared channel (PUSCH), and aperiodic reporting methods are mentioned (see 3GPP TS 38.331 V18.0.0 ). All these measurement reports are carried via uplink control information(UCI). The following extract from 3GPP TS 38.331 V18.0.0 shows the LTM measurement report configurations for each of these reporting types:LTM-CSI-ReportConfig-rl8 ::= SEQUENCE {Itm-CSI-ReportConfigld-r 18 LTM-CSI-ReportConfigld-rl 8,Itm-ResourcesForChannelMeasurement-rl 8 LTM-CSI-ResourceConfigld-rl 8, Itm-ReportConfigType-rl 8 CHOICE {periodic-rl 8 SEQUENCE {reportSlotConfig-rl 8 CSI-ReportPeriodicityAndOffset, pucch-CSI-ResourceList-rl 8 SEQUENCE (SIZE (L.maxNroffiWPs)) OF PUCCH-CSI-ResourcesemiPersistentOnPUCCH-rl 8 SEQUENCE {reportSlotConfig-rl 8 CSI-ReportPeriodicityAndOffset, pucch-CSI-ResourceList-rl 8 SEQUENCE (SIZE (l. maxNroffiWPs)) OF PUCCH-CSI-ResourcesemiPersistentOnPUSCH-rl 8 SEQUENCE {reportSlotConfig-rl 8 CSI-ReportPeriodicityAndOffset, reportSlotOffsetList-r 18 SEQUENCE (SIZE (1.. maxNrofUL- Allocations-rl 6)) OF INTEGER (0..128),reportSlotOffsetListDCI-O-2-r 18 SEQUENCE (SIZE (1.. maxNrofUL- Allocations-rl 6)) OF INTEGER (0..128),reportSlotOffsetListDCI-O- 1 -r 18 SEQUENCE (SIZE (1.. maxNrofUL- Allocations-rl 6)) OF INTEGER (0..128),pOalpha PO-PUSCH-AlphaSetldaperiodic-r!8 SEQUENCE {reportSlotOffsetList-r 18 SEQUENCE (SIZE (1.. maxNrofUL- Allocations-rl 6)) OF INTEGER (0..128),reportSlotOffsetListDCI-O-2-r 18 SEQUENCE (SIZE (1.. maxNrofUL- Allocations-rl 6)) OF INTEGER (0..128),reportSlotOffsetListDCI-O- 1 -r 18 SEQUENCE (SIZE (1.. maxNrofUL- Allocations-rl 6)) OF INTEGER (0..128)Itm-ReportContent-r 18 LTM-ReportContent-r 18,LTM-ReportContent-r 18 ::= SEQUENCE {nrOfReportedCells-r!8 ENUMERATED {nl,n2,n3,n4}, nrOfReportedRS-PerCell-r!8 ENUMERATED {nl,n2,n3,n4}, spCelllnclusion-rl 8 ENUMERATED {true}

[0004] As indicated above, the periodic report in LTM can only be carried via PUCCH and the associated PUCCH resource configuration for report transmission, reporting periodicity, and offset are provided via RRC configuration in the serving cell. The semi-persistent report in LTM can be carried via PUSCH or PUCCH, and the transmission of a semi-persistent report is activated via medium access control (MAC) control element (CE). Aperiodic reports in LTM can only be carried via PUSCH and the transmission of the aperiodic LTM CSI report is polled via downlink control information (DCI) (see 3GPP TS 38.331, V18.0.0).Event-Triggered Reporting in LTM Rel-19

[0005] The Rel-19 work item for LTM aims to remove the limitations in Rel-18 LTM. Some of the objectives for the Rel. 19 WID “NR mobility enhancements Phase 4” (3GPP RP-241515) are set out below:Measurements related enhancements for purpose of supporting LTM: [RAN2, RANI]• Measurement related enhancements are applicable to Intra-CU MCG / SCG LTM and Inter-CU MCG / SCG LTM• Specify necessary components to support event triggered LI measurement reporting [RAN2, RANI],• Specify support for CSI-RS measurements for LTM procedures and enable CSI-RS based beam management [RANI]• Specify CSI acquisition on candidate cell(s) based on CSI-RS before or during LTM cell switch [RANI]

[0006] As part of the “Measurements-related enhancements” in LTM, Rel-19 LTM defines “Event-triggered Ll-Reporting” in LTM to address the following issues:• Excessive energy consumption at the UE due to high reporting overhead in periodic and semi-persistent LI -report types in LTM.• Inefficient use of UL resources in periodic and semi-persistent LI -report types in LTM.• If the reporting interval in the periodic and semi -persistent LI -reports is increased in LTM to enhance energy and UL resource efficiency, it may result in handover failures and / or radio link failures (RLF) due to delayed updates in the channel quality at the network.• Aperiodic LI -report in LTM may result in RLF if the report is not requested by the network in a timely manner.

[0007] There currently exist certain challenges. In the L3 measurement and reporting framework, cell-level measurements trigger the L3 event for handover and it is possible to include the individual beam measurements from the triggering cell within the L3 measurement report, in addition to the cell-level measurements. The reporting of beam-level measurements provides the network with information about the individual beam quality in the cell which triggered the event and hence the measurement report.

[0008] According to the most recent agreements in LTM Rel-19 “Measurement-related enhancements” WI, it is possible to report on the LTM candidate cell beam(s) or reference signal(s) which do not fulfill the event condition(s) and that a maximum of N beams can be included, which are a part of LTM resource configuration for the given LTM event, as mentioned below:1. For event-triggered LI LTM measurement reporting, max N is total number of all beams included into MR MAC CE.2. For event-triggered LI LTM measurement reporting, network controls if the beam(s) not satisfying the event could be reported according to N beams in measurement report MAC CE.

[0009] According to this agreement, when an LI event condition is fulfilled and the UE is triggered to send a LI measurement report, the network can control if the beams which have not fulfilled any event are to be included or not, but the agreement does not describe how. In other words, it is not agreed which LTM candidate cell beam(s) and / or LTM candidate cells should be reported given that those beam(s) did not fulfil the event condition but are still a part of the measurement resource configuration, associated to the triggering event. If the aforementioned information is reported without clearly specifying how, this may cause different problems:• The UE may report beam(s) which have not fulfilled event condition(s) with a particularly low measurement quantity, and this means that the network cannot use these measurement results to trigger a mobility procedure. The result is that the cell switch of the UE may be delayed, and the number of failures may increase. To further elaborate, if there are no rules to select proper non-triggered beams, the UE may leave out of the LTM measurement report good beams which could have otherwise been selected by the network for contention-free random access, and / or for provisioning of an UL grant in the case of a RACH-less LTM Cell Switch, in response to the LTM measurement report.• The UE may decide to report beams which have not fulfilled event condition(s) by leaving out of the LTM measurement report the beam(s) which has actually fulfilled the event condition(s) i.e., triggered beams. In this case, the content of the report will not be optimal, and the UE may not provide meaningful information thus leading to sub-optimal decisions in case the network triggers a mobility procedure.• If the UE reports a large number of beams which have not fulfilled an event condition(s), the size of the report may also be quite large, and this may increase the signaling overhead and waste radio resources for transmitting the report.• If the UE reports non-triggered beams together with triggered beams, i.e., the beam(s) which fulfil the event condition(s), the network cannot determine whether a certain beam is triggered or non-triggered, since there may be non-triggered beams with good radio conditions (e.g., high LI RSRP) which do not fulfill the condition because the quality was not high during the time-to-trigger (TTT) duration.• If the UE has no information available from the network to report on the nontriggered beam(s), then there is no additional information provided to the network about the other beam(s)’ quality for the LTM candidate cell whose beam / reference signal triggered the LTM event.Summary

[0010] Certain aspects of the disclosure and their embodiments may provide solutions to these or other challenges. The proposed solution describes the methods at the UE in which the UE receives (from a first network node e.g., source gNodeB, a source Distributed Unit, a source Centralized Unit) in an LTM reporting configuration one or more parameters based on which the UE determines how to include in an LTM measurement report one or more nontriggered beams or reference signals (RS), e.g., synchronization signal block (SSB)-RS / channel state information (CSI)-RS. In this context, non-triggered beams are the beams of LTM candidate cells which do not fulfil the condition(s) for time-to-trigger (TTT) duration defined for an LTM event which triggered the LTM measurement report, such that the beams / reference signals belong to the LTM measurement resource configuration which is associated to the given event.

[0011] The method discloses different options for the one or more parameters, on how the UE determines to include the non-triggered beams, and what the UE includes in the LTM measurement report.

[0012] According to a main embodiment of the method, the one or more parameters received by the UE, in the LTM reporting configuration, comprise at least one threshold value for selecting ‘good’ non-triggered beams so the UE includes non-triggered beams having a measurement quantity (e.g., LI RSRP) that is above the threshold. Then, the UE includes the triggered beams up to another parameter defines as the maximum number of beams to include (‘N’) and, when the number of triggered beams for that LTM measurement reporting is lower than ‘N’, the UE further includes in the LTM measurement report one or more ’good’ nontriggered beams, up to ‘N’. For example, when the UE includes KI triggered beams in the LTM measurement report and K1<=N, the UE includes K2 non-triggered ‘good’ beams (K1+K2=N) i.e., the K2 non-triggered beams having the measurement quantity (e.g., LI RSRP) above the threshold. In one option, the UE receives in the LTM reporting configuration a single threshold, which is associated to multiple reference signals (e.g., SSB and CSI-RS) for beams transmitted by the network; in another option, the UE receives a threshold per reference signal in which beams are transmitted by the network e.g., one threshold for selecting beams transmitted on SSBs, and another threshold for beams transmitted on CSI-RSs.

[0013] According to the method, the UE includes at least one non-triggered beam in the LTM measurement report i.e., the UE includes a resource indication for that non-triggered beam, such as a resource indication (e.g., SSB resource indicator or a CSI-RS resource indicator) which indicates the index of the reference signal and the associated LTM candidate cell, and an indication that such beam is a non-triggered beam e.g., a tag and / or a label and / or a bit and / or a flag in the LTM measurement report and possibly a measurement information, such as LI -RSRP value or differential LI -RSRP value.

[0014] Embodiments of the present disclosure also include a method at a first network node (a source gNodeB, a source Distributed Unit, a source Centralized Unit) which transmits to the UE an LTM reporting configuration which configures an event or criteria to send an LTM measurement report for the beams / reference signals which neither trigger the LTM measurement reporting nor fulfil the given LTM event condition(s) for the given TTT, wherein the LTM reporting configuration includes one or more parameters based on which the UE determines how to include in an LTM measurement report one or more non-triggered beams or reference signals (RS), e.g., synchronization signal block (SSB)-RS / channel state information (CSI)-RS.

[0015] The method at the first network node comprises the first network node receiving an LTM measurement report and including at least one non-triggered beam (e.g., a resourceindicator, like an SSBRI, associated to a reference signal in which a beam is transmitted by the network) and an indication that such non-triggered beam is a non-triggered beam e.g., SSBRI associated to a flag indicating this is non-triggered.

[0016] One aspect of the disclosure provides a method performed by a wireless device. The method comprises receiving, from a network node of a network, one or more configurations. The one of more configurations comprise at least one LTM candidate cell configuration for at least one LTM candidate cell, a measurement configuration indicating resources on which the wireless device is to perform measurements, and a reporting configuration for reporting measurement values obtained in accordance with the measurement configuration. The reporting configuration indicates one or more criteria for determining whether to include one or more triggering measurement values and / or one or more non-triggering measurement values in measurement reports. The method further comprises: performing measurements in accordance with the measurement configuration to obtain measurement values; detecting, using the measurement values, an event that triggers transmission of a measurement report; and transmitting, to the network, a measurement report. The measurement report comprises indications of one or more of the measurement values selected for inclusion in the measurement report according to the reporting configuration.

[0017] Another aspect of the disclosure provides a method performed by a network node of a network. The method comprises: transmitting, to a wireless device, one or more configurations. The one of more configurations comprise at least one LTM candidate cell configuration for at least one LTM candidate cell, a measurement configuration indicating resources on which the wireless device is to perform measurements, and a reporting configuration for reporting measurement values obtained in accordance with the measurement configuration. The reporting configuration indicates one or more criteria for determining whether to include one or more triggering measurement values and / or one or more non-triggering measurement values in measurement reports.

[0018] Further aspects of the disclosure provide apparatus and computer-readable media for performing the methods set out above.

[0019] Certain embodiments may provide one or more of the following technical advantage(s). For example, embodiments (e.g., methods) provided in the present disclosure offer the following advantages:• Selecting only ‘good’ non-triggered beams is beneficial since reporting on the bad quality non-triggered beam(s) is not useful for the network and would represent onlyunnecessary overhead in LTM measurement reporting. On the other hand, reporting nontriggered beams of an LTM candidate cell which is a potential candidate for an LTM Cell Switch may be useful since network may allocate multiple beams (e.g., SSBs) with contention free random access resources (in case of a contention free LTM Cell Switch) and / or provide for multiple beams, triggered and / or non-triggered, multiple UL grant(s) (if enabled to be provided dynamically in an LTM Cell Switch).• UE reports the remaining beams of good enough quality to inform the network about more stable beams in the LTM cell which in turn enables the network to perform early UL / DL synchronization as well as the LTM cell switch to the LTM candidate cells with overall better and more stable cell quality.• Indicating in the LTM measurement report that a beam which is included is a nontriggered beam is beneficial because a non-triggered beam may have a good quality but for an insufficient duration i.e. for the duration of the time-to-trigger, so that the network should know whether that has been confirmed to be a stable beam or not necessarily (in case a non-triggered beam has good quality, but is not necessarily a triggered beam).Brief Description of the Drawings

[0029] Some of the embodiments contemplated herein will now be described more fully with reference to the accompanying drawings. Embodiments are provided by way of example to convey the scope of the subject matter to those skilled in the art.Initial Description

[0030] The method disclosed is applicable for LTM, thus the text refers to the term “L 1 / L2 based inter-cell mobility (LTM)” as defined in Release 18, though it interchangeably also uses the terms L1 / L2 mobility, Ll-mobility, LI based mobility, Ll / L2-centric inter-cell mobility, L1 / L2 inter-cell mobility Ll / L2-Triggered Mobility (LTM), Lower-layer triggered Mobility or simply LTM, as more widely used. The basic principle is that the UE receives a lower layer signaling from the network (e.g., a MAC Control Element - MAC CE) indicating to the UE a change (or switch or activation) of its serving cell (i.e., PCell or PSCell), wherein a lower layer signaling is a message / signaling carried via a lower layer protocol, which may be referred as a L1 / L2 inter-cell mobility execution command or LTM cell switch command. Before the UE receives the LTM cell switch command, the UE is configured by the network with one or more LTM candidate cell configurations (e.g., reception of an RRC Reconfiguration message, with at least one LTM candidate cell configuration). An LTM candidate cell configuration may include parameters in the IE CellGroupConfig per candidate cell and / or an embedded RRC Reconfiguration per LTM candidate cell. An LTM configuration may include one or multiple of the following type of elements where each element contains a configuration of one aspect of LTM, for example as follows:• LTM candidate cell configuration(s),• Inter-CU LTM candidate cell configuration(s),• Lower layer information, such as physical layer configuration, MAC layer configuration or RLC layer configuration, Cell Group configuration, serving cell configuration.• Higher layer information, such as RRC protocol parameters, such as timer values, PDCP layer configuration, radio bearer configuration or measurement configuration • Configuration of measurements for LTM• Configuration for measurement reports for LTM• CSI resource configuration(s) for LTM• CSI report configuration for LTM• Configurations of early synchronization procedures, such aso Configurations for DL pre-sync for LTM, such as configurations for early TCI state activationo Configurations for UL pre-sync for LTM, such as configurations for reception of PDCCH ordered triggered preamble transmission and reception of TA. • Configurations for the execution of an LTM cell switch procedure for a given LTM candidate cell configuration or inter-CU LTM candidate cell configuration (e.g., whether to perform random access procedure, whether to perform RLC reestablishment, or MAC reset, or PDCP recovery), a timer value, configured UL grants, dedicated RA preambles.• A configuration which the UE utilizes to start to operate accordingly when it performs an LTM cell switch procedure to an LTM candidate cell which is controlled by a different base station, e.g. gNB, from the current source base station e.g. serving gNB of the UE.• Information to perform security key refresh, e.g. the RRC IE MasterKey Update or a RRC IE RadioBearerConfig that includes SecurityConfig withS ecurity AlgorithmC onfig.• Indication to perform a full configuration, e.g. the RRC field fullConfig.• Indication to perform L2 re-establishment, such as an indication to perform PDCP reestablishment for one or multiple bearers.

[0031] An LTM candidate cell may refer to a cell for which the UE may be configured to perform lower layer measurements, such as Layer 1 (LI) reference signal received power (RSRP), on the synchronization signal block (SSB) and / or channel state information reference signal (CSI-RS), e.g., LTM CSI measurements. Lower layer measurements are measurements reported to support lower layer procedures like beam management, TCI state activations / deactivations, early timing advance (TA) acquisition, and link adaptation, and they aren't filtered based on Layer 3 (L3) parameters, though there may (or may not) be some filtering of these measurements based on lower layer parameters. The UE reports these measurements, and the network takes an informed decision on which beam (e.g., TCI state) and / or cell the UE is to be switched to. In the case of an LTM fast failure recovery, when a failure is detected, the UE selects a cell and when the cell is an LTM candidate cell the UE does not have to perform re-establishment, but instead performs an LTM cell switch towardsthe selected LTM candidate cell e.g., by applying the LTM candidate cell configuration associated to the selected LTM candidate cell.

[0032] An LTM cell switch procedure or LTM execution procedure may be triggered in the UE by reception of an LTM cell switch command (e.g., LTM Cell Switch MAC CE), or alternatively, triggered in response to the detection of a failure (in case of LTM fast failure recovery). The text refers to an LTM candidate cell, which is a cell the UE is configured with when configured with Ll / L2-triggered mobility. That is a cell the UE can move to in an LTM cell switch procedure, upon reception of an LTM cell switch command. These cells may also be termed as candidate cell(s), candidates, candidate target cell, implied target cell, mobility candidates, non-serving cells, additional cells, or deactivated cells etc. An LTM candidate cell might also pertain to a candidate cell in a 5G Radio Access Technology like NR or a future 6G Radio Access Technology.

[0033] The reference signals on which lower layer measurements are performed may be provided in the LTM CSI-SSB Resource Set, under LTM CSI Resource Configuration. A resource identifier for a reference signal resource, such as a serving cell or an LTM candidate cell SSB-Index or CSI-RS-Resource ID, uniquely identifies the resource in the LTM configuration and among all the serving and LTM candidate cells. The resource identifier can be understood by both the UE and the serving gNB. In the context of LTM, the reference signal resource identifier is described by the field LTM-CSI-SSB-ResourceSet in TS 38.331 V18.2.0: LTM-CSI-SSB-ResourceSet-rl8 ::= SEQUENCE {ltm-CSI-SSB-ResourceList-r!8 SEQUENCE (SIZE (L.maxNrofLTM-CSI-SSB-ResourcesPerSet-rl8)) OF SSB-Index,ltm-Candidate!dList-rl8 SEQUENCE (SIZE (L.maxNrofLTM-CSI-SSB-ResourcesPerSet-rl8)) OF LTM-Candidateld-rl 8,

[0034] In the example, the ith position of the list in the field Itm-CSI-SSB-ResourceList indicates the SSB ID of the reference signal resource, while the same ith position of the list in the field Itm-CandidateldList indicates to which LTM candidate configuration index the SSB belongs.

[0035] According to the method, the ‘measurement configuration’ may correspond to an LTM resource configuration (and / or a resource set configuration). The UE may receive this configuration in an RRC Reconfiguration (or RRC Resume) message, wherein each ‘LTM resource’ to be measured and to be possibly reported (depending on further rules of the method) corresponds to a Reference Signal indication (e.g., an SSB index and / or a CSI-RS resourceindication) and its associated LTM Candidate Identity (ID), to indicate a specific RS (e.g., SSB index) of an LTM candidate.

[0036] According to the method, a measurement configuration (i.e. resource configuration, resource set configuration) may be associated with a reporting configuration (or LTM reporting configuration), by including within a reporting configuration an indication of a resource configuration (or a resource set configuration). For example, when the reporting configuration is configured in the IE LTM-ReportConfig, the instance of the IE LTM-ReportConfig includes a resource configuration (or resource set configuration) identifier, pointing to the associated measurement configuration.

[0037] According to the method, the ‘measurement reporting configuration’, or simply “reporting configuration” may correspond to an LTM reporting configuration the UE receives in an RRC Reconfiguration (or RRC Resume) message, in which an event for triggering an LTM measurement report (e.g. over MAC CE and / or UCI) is configured. An event, for example, can be defined as “a measurement quantity (e.g., LI RSRP) of an SSB (or CSI-RS or beam) of an LTM candidate cell becomes an offset better than the same measurement quantity (e.g. LI RSRP) of a serving SSB (e.g. SSB of the PCell associated to an activated and / or indicated TCI state)”. The actual SSBs of the LTM candidate cell(s) to be measured are configured in the measurement configuration (or resource set or resource configuration) associated to that LTM reporting configuration. It could also be said that the event definition is like one or more conditions to be evaluated. As per Rel-18 LTM, the different types of measurement reports in LTM include periodic reporting, semi-persistent reporting, and aperiodic reporting. However, Rel-19 also introduces event-triggered report type in LTM which is transmitted upon the fulfilment of the associated event condition(s).

[0038] An LI event type in LTM may refer to a class of events, e.g. LTM2, LTM3, LTM4, LTM5. An LI event or event instance is an instance of an event type, e.g. an LTM3 event configured with certain parameters like offset, threshold, time-to-trigger (TTT) etc., and associated with an LTM resource configuration. An LI event identifier uniquely identifies an event instance and can be understood by both the UE and the serving gNB. The condition(s) defined in the LTM events are also referred to as triggering condition(s), event condition(s), LTM event condition(s), event trigger condition(s) or simply trigger condition(s) in the text.

[0039] A measurement quantity may refer to any one or more of:• Ll-RSRP from SS-RSRP or CSI-RSRP, or• LI- signal-to-interference and noise ratio (SINR) from SS-SINR or CSI-SINR, or• LI- reference signal received quality (RSRQ) from SS-RSRQ or CSI-RSRQ,

[0040] The measurement quantity value may refer to the value which the UE reports for the measurement quantity (e.g., of an SSB or a CSI-RS resource). In Rel-18 LTM Ll-reporting, the measurement quantity is primarily the SS-RSRP for the LTM measurement resource with the highest measurement and differential SS-RSRP value(s) with respect to the highest SS-RSRP measurement. A triggering measurement quantity value for an event may be a measurement quantity value that meets the conditions for the event (e.g., throughout the TTT duration) and hence triggers the UE to send the measurement report. A non-triggering measurement quantity value for an event may be a measurement quantity value that does not meet the conditions for the event (e.g., throughout the TTT duration) and hence does not trigger the UE to send the measurement report.

[0041] The text of the present disclosure uses different terms for LTM reports, which include lower layer report, lower layer measurement report, lower layer reporting, LI -report, LI -measurement report, LI event triggered measurement report, Ll-reporting, LTM measurement report interchangeably without any loss of meaning. For the event-triggered LTM reports, the text of the present disclosure uses the terms event-triggered LI -report, event-triggered LI -measurement report, event-triggered lower layer measurement report, event-triggered lower layer reporting, event-triggered Ll-reporting, LI -measurement report, LI event triggered measurement report, LTM measurement report, LTM event triggered measurement report interchangeably.

[0042] The text uses the term “cell” to identify a location (or coverage) on which the UE is located. However, the term “cell” can also be exchanged without any loss of meaning with the terms “radio resources”, “beams”, “TCI state”, or “tracking reference signal (TRS)”. This is just to clarify that embodiments of the present disclosure do not necessarily target specifically a scenario where there is a cell, but rather when a UE uses a set of source radio resources and switches to a target set of radio resources. In such a case, “radio resource” can also identify a set of configurations, field, parameters, or ASN.1 structures or IES. The text also uses the terms like non-fulfilling beams or non-fulfilling reference signals which are the SSB-RS / CSI-RS which do not fulfil the condition(s) defined for the given LTM event. Moreover, the text uses the term “first network node” to refer to a source cell / serving cell / source gNB-DU / S-DU.

[0043] In the context of the present disclosure, a “triggered resource” may refer to a resource of a triggered LTM candidate cell (e.g., a beam, a cell, a reference signal, a synchronization signal, etc.,) which fulfills a triggering condition (which may also be referredto herein as a “triggering criterion”) for transmitting an LTM measurement report. For example, one or more measurements performed on the resource may fulfill the triggering condition. A triggered resource may have been configured as part of the LTM resource configuration and associated to an LTM candidate cell.

[0044] In the context of the present disclosure, a “triggered cell” may refer to a triggered LTM candidate cell, which is an LTM candidate cell for which a beam, or Reference Signal (e.g. CSI-RS, SSB) or Synchronization Signal (e.g., SSB) transmitted in a beam, fulfill a triggering condition for transmitting a measurement report. A triggered LTM candidate cell may have been configured as part of the LTM resource configuration.

[0045] For example, in the context of the present disclosure, a “triggered beam” may refer to a beam of a triggered LTM candidate cell (e.g., a beam, or a Reference Signal (e.g. CSI-RS, SSB) or Synchronization Signal (e.g. SSB) transmitted in a beam, etc.,) which fulfills a triggering condition for transmitting an LTM measurement report. A triggered beam may have been configured as part of the LTM resource configuration and associated to an LTM candidate cell.

[0046] In the context of the present disclosure, a “non-triggered resource” may refer to a resource of a triggered LTM candidate cell (e.g., a beam, a cell, a reference signal, a synchronization signal, etc.,) which does not fulfill a triggering condition for transmitting an LTM measurement report. For example, one or more measurements performed on the resource may not fulfill the triggering condition. A non-triggered resource may have been configured as part of the LTM resource configuration and associated to an LTM candidate cell.

[0047] In the context of the present disclosure, a “non-triggered cell” may refer to a nontriggered LTM candidate cell, which is a cell for which any resource (e.g., beam, Reference Signal (e.g. CSI-RS, SSB) or Synchronization Signal (e.g. SSB) transmitted in a beam, etc.) does not fulfill the triggering condition the UE is configured with, for transmitting an LTM measurement report. A non-triggered LTM candidate cell may have been configured as part of the LTM resource configuration.

[0048] In the context of the present disclosure, a “non-triggered beam” may refer to a beam, or Reference Signal (e.g., CSI-RS, SSB) or Synchronization Signal (e.g., SSB) transmitted in a beam, which does not fulfill a triggering condition for transmitting an LTM measurement report. A non-triggered beam may have been configured as part of the LTM resource configuration and associated to an LTM candidate cell. In other words, for a given LTM measurement report, triggered to be transmitted according to a specific triggeringcondition configured in a specific reporting configuration, the non-triggered beam is a beam which does not fulfill that condition.

[0049] Figure 2 depicts a method in accordance with particular embodiments. The method may be performed by a wireless device (e.g. UE 412, station 512 or wireless device 600 as described later with reference to Figures 4, 5 and 6 respectively). In embodiments of Figure 2, the method may incorporate any of the embodiments discussed below in the section entitled “UE-related embodiments”. It is noted that Figure 2 discloses a complementary method to the one illustrated in Figure 3.

[0050] The method begins at step 202, in which the wireless device receives, from a network node (e.g., a RAN node) of a network, one or more configurations.

[0051] The one of more configurations comprise at least one LTM candidate cell configuration for at least one LTM candidate cell.

[0052] The one or more configurations comprise a measurement configuration (which may be referred to herein as a “LTM measurement resource configuration”) indicating resources on which the wireless device is to perform measurements. For example, the resources may include any one or more of: beams, reference signals (e.g., corresponding to beams), and cells (e.g., the at least one LTM candidate cell and / or a serving cell of the wireless device). The measurement configuration may be associated with and / or specific to the LTM candidate cell configuration.

[0053] The one or more configurations also comprise a reporting configuration (which may be referred to herein as a “LTM reporting configuration”) (e.g., associated with and / or specific to a particular cell of the wireless device) for reporting measurement values obtained in accordance with the measurement configuration. The reporting configuration may indicate one or more criteria for determining whether to include one or more triggering measurement values (also referred to herein as triggering measurement quantity values, as defined above) and / or one or more non-triggering measurement values in measurement reports (also referred to herein as non-triggering measurement quantity values, as defined above).

[0054] In the context of the present disclosure, a non-triggering measurement value may be a measurement value that is not associated with an event triggering transmission of the first measurement report. Similarly, a triggering measurement value may be a measurement value that is associated with an event triggering transmission of the first measurement report.

[0055] The one or more criteria may indicate that non-triggering measurement values are prohibited from inclusion in the measurement report. In this case, a wireless device reportingin accordance with the reporting configuration would not select any non-triggering measurement values for inclusion in a measurement report triggered for transmission to the network.

[0056] In other examples, the one or more criteria may indicate that non-triggering measurement values are to be included in the measurement report (e.g., allowed to be included in the measurement report). In this case, a wireless device may, as part of its selection of measurement values to be included in the measurement report in accordance with the reporting configuration, select non-triggering measurement values for inclusion in the measurement report.

[0057] The way in which the wireless device may be configured (via the reporting configuration) to select non-triggering measurement values for inclusion in the measurement report is discussed below. See embodiments A1-A9 below for more details.

[0058] For example, the reporting configuration may indicate (as part of the one or more criteria) instructions for how the wireless device is to report non-triggering measurement values. A number of examples of such indicated instructions are provided below. It should be appreciated that in embodiments of the present disclosure, the one or more criteria may include any one (or combination of) the following example indications.• In an example, the one or more criteria may indicate a (e.g., maximum, minimum, and / or specific) number of measurement values to be included in the measurement report (e.g., parameter ‘TV5discussed below).• In an example, the one or more criteria may indicate a (e.g., maximum, minimum, and / or specific) number of non-triggering measurement values to be included in the measurement report (e.g., parameters ‘N , ‘7V2’, ‘N3’ etc., discussed below).• In an example, the one or more criteria may indicate a (e.g., maximum, minimum, and / or specific) number of triggering measurement values to be included in the measurement report.• In an example, the one or more criteria may indicate a (e.g., maximum, minimum, and / or specific) number of resources for which measurement values are to be included in the measurement report (e.g., nrOfReportedCell, nrOfReportedBeamsPerCell, discussed below).• In an example, the one or more criteria may indicate a (e.g., maximum, minimum, and / or specific) number of non-triggering measurement values,obtained for a given non-triggering resource, that are to be included in the measurement report.• In an example, the one or more criteria may indicate a (e.g., maximum, minimum, and / or specific) number of non-triggering resources for which nontriggering measurement values are to be included in the measurement report (e.g., nrOfNonTriggeredCells discussed below)..• In an example, the one or more criteria may indicate a (e.g., maximum, minimum, and / or specific) number of triggering resources for which triggering measurement values are to be included in the measurement report.

[0059] The reporting configuration may indicate any one of fields, data locations, and a number of triggering and / or non-triggering measurement values that are to be used in the measurement report for any one or more of the following:- indicating (e.g., implicitly or explicitly) whether one or more of the measurement values included in the measurement report are non-triggering measurement values;- indicating (e.g., implicitly or explicitly) whether one or more of the measurement values included in the measurement report are triggering measurement values;- reporting triggering measurement values;- reporting non-triggering measurement values;- indicating (e.g., implicitly or explicitly) one of the at least one LTM candidate cell and / or a serving cell of the wireless device that is associated with a respective measurement value of the one or more measurement values.

[0060] In some examples, the one or more criteria may include reporting criteria (e.g., a reporting threshold or a reporting offset with respect to a measurement value for a resource serving the wireless device). If anon-triggering measurement value fulfils the reporting criteria (e.g., meets the reporting threshold or falls within the range defined by the reporting offset), the non-triggering measurement value may be considered eligible for inclusion in the measurement report and / or have a higher priority for inclusion in the measurement report over non-triggering measurement values that did not fulfil the reporting requirement.

[0061] The reporting criteria may be associated with a signal quality (e.g., Ll-RSRP) indicated by the non-triggering measurement value. In this case, non-triggering measurement values that meet signal quality criteria (e.g., high signal quality) may be included in the measurement report.

[0062] The reporting criteria may be defined relative to triggering criteria (e.g., a triggering threshold or a triggering offset with respect to a measurement value for a resource serving the wireless device) which, upon fulfilment by at least one of the measurement values, triggers transmission of the measurement report. This triggering criteria is discussed in more detail below, with reference to step 206.

[0063] The one or more criteria may indicate that triggering measurement values are to be prioritized for inclusion in the measurement report over non-triggering measurement values. In such cases, the wireless device may utilise the indicated instructions above when selecting whether certain triggering and non-triggering measurement values are to be included in the measurement report. For example, the wireless device may first select triggering measurements for inclusion in the measurement report according to the one or more criteria discussed above. Then, if the one or more criteria allow (e.g., are not violated as a result), the wireless device may select one or more non-triggering measurement values for inclusion in the measurement report. See embodiment A4 below for more details.

[0064] The one or more criteria may indicate that non-triggering measurement values of a first type are to be prioritized for inclusion in the measurement report over non-triggering measurement values of a second type). The non-triggering measurement values of the first type may be prioritized for inclusion in the measurement report over the non-triggering measurement values of the second type based on any one of more of:• the non-triggering measurement values of the first type indicating a higher signal quality (e.g., Ll-RSRP) than the non-triggering measurement values of the second type (e.g., based on the non-triggering measurement values of the first type having a higher ranking than non-triggering measurement values of the second type, wherein the ranking is based on indicated signal quality of the non-triggering measurement value);• an activation of a first TCI state(s) corresponding to the non-triggering measurement values of the first type and / or an activation of the second TCI state(s) corresponding to the non-triggering measurement values of the second type (e.g., based on the first TCI state(s) being activated and the second TCI state(s) not being activated); and• a synchronization state of a first resource corresponding to the non-triggering measurement value of the first type and / or a synchronization state of a second resource corresponding to the non-triggering measurement value of the secondtype (e.g., based on the first resource being in uplink synchronization and the second resource not being in uplink synchronization).

[0065] It should be noted that the one or more configurations may be transmitted to the wireless device, from the network node, in the same message (e.g., in an RRC message or any other suitable message). Alternatively, the one or more configurations may be included in a plurality of messages sent from the network node. For example, individual configurations (or part thereof) may be included in respective ones of the plurality of messages. In other examples, more than one configuration (or parts thereof) may be included in respective ones of the plurality of messages.

[0066] Returning to Figure 2, at step 204, the method comprises performing measurements in accordance with the measurement configuration to obtain measurement values (e.g., LI measurement values).

[0067] At step 206, the method comprises detecting, using the measurement values, an event (e.g., an LI event) that triggers transmission of a measurement report. In some examples, the event may comprise triggering criteria (e.g., the triggering threshold or the triggering offset) being fulfilled by at least one of the measurement values. That is, a measurement value for a resource may meet the triggering threshold or fall within a range defined by the triggering offset.

[0068] The method of Figure 2 may further comprise the wireless device selecting one or more measurement values for inclusion in a measurement report according to the reporting configuration (e.g., based on the priority of the one or more measurement values for inclusion in the measurement report).

[0069] At step 208, the method comprises transmitting, to the network, the measurement report. The measurement report comprises indications of the one or more of the measurement values selected for inclusion in the measurement report according to the reporting configuration.

[0070] For example, the measurement report may be transmitted to the same network node from which the wireless device received the one or more configurations. Alternatively, the measurement report may be transmitted to a different network node (i.e., a network node that did not transmit the one or more configurations).

[0071] Figure 3 depicts a method in accordance with particular embodiments. The method may be performed by a network node (e.g. network node 410, access point 510 or network node 700 as described later with reference to Figures 4, 5 and 7 respectively). In embodimentsof Figure 3, the method may incorporate any of the embodiments discussed below in the section entitled “network-related embodiments”. The method of Figure 3 describes steps taken by a network node (e.g., a network node serving the wireless device), and in some embodiments these steps correspond to the complementary method described above with respect to Figure 2 but from the network node’s perspective. Accordingly the reader is directed towards the description above for further detail regarding the method of Figure 3.

[0072] The method begins at step 302, in which the network node transmits, to a wireless device, one or more configurations. It is noted that step 302 corresponds to step 202 in Figure 2.

[0073] The one or more configurations comprise at least one LTM candidate cell configuration for at least one LTM candidate cell.

[0074] The one or more configurations comprise a measurement configuration indicating resources on which the wireless device is to perform measurements. For example, the resources may include any one or more of: beams, reference signals (e.g., corresponding to beams), and cells (e.g., the at least one LTM candidate cell and / or a serving cell of the wireless device). The measurement configuration may be associated with and / or specific to the LTM candidate cell configuration.

[0075] The one or more configurations also comprise a reporting configuration (e.g., associated with and / or specific to a particular cell of the wireless device) for reporting measurement values (e.g., LI measurement values) obtained in accordance with the measurement configuration. The reporting configuration may indicate one or more criteria for determining whether to include one or more triggering measurement values (also referred to herein as triggering measurement quantity values, as defined above) and / or one or more nontriggering measurement values in measurement reports (also referred to herein as nontriggering measurement quantity values, as defined above).

[0076] As discussed above, in the context of the present disclosure, a non-triggering measurement value may be a measurement value that is not associated with an event triggering transmission of the first measurement report. Similarly, a triggering measurement value may be a measurement value that is associated with an event triggering transmission of the first measurement report.

[0077] The one or more criteria may indicate that non-triggering measurement values are prohibited from inclusion in the measurement report. In this case, a wireless device reporting in accordance with the reporting configuration would not select any non-triggeringmeasurement values for inclusion in a measurement report triggered for transmission to the network.

[0078] In other examples, the one or more criteria may indicate that non-triggering measurement values are to be included in the measurement report (e.g., allowed to be included in the measurement report). In this case, a wireless device may, as part of its selection of measurement values to be included in the measurement report in accordance with the reporting configuration, select non-triggering measurement values for inclusion in the measurement report.

[0079] The way in which the network node may configure the wireless device (via the reporting configuration) to select non-triggering measurement values for inclusion in the measurement report is discussed below. Embodiments B1-B8 below also provide additional details.

[0080] For example, the reporting configuration may indicate (as part of the one or more criteria) instructions for how the wireless device is to report non-triggering measurement values. A number of examples of such indicated instructions are provided below. It should be appreciated that in embodiments of the present disclosure, the one or more criteria may include any one (or combination) of the following example indications.• In an example, the one or more criteria may indicate a (e.g., maximum, minimum, and / or specific) number of measurement values to be included in the measurement report.• In an example, the one or more criteria may indicate a (e.g., maximum, minimum, and / or specific) number of non-triggering measurement values to be included in the measurement report.• In an example, the one or more criteria may indicate a (e.g., maximum, minimum, and / or specific) number of triggering measurement values to be included in the measurement report.• In an example, the one or more criteria may indicate a (e.g., maximum, minimum, and / or specific) number of resources for which measurement values are to be included in the measurement report.• In an example, the one or more criteria may indicate a (e.g., maximum, minimum, and / or specific) number of non-triggering measurement values, obtained for a given non-triggering resource, that are to be included in the measurement report.• In an example, the one or more criteria may indicate a (e.g., maximum, minimum, and / or specific) number of non-triggering resources for which nontriggering measurement values are to be included in the measurement report.• In an example, the one or more criteria may indicate a (e.g., maximum, minimum, and / or specific) number of triggering resources for which triggering measurement values are to be included in the measurement report.

[0081] The reporting configuration may indicate any one of fields, data locations, and a number of triggering and / or non-triggering measurement values that are to be used in the measurement report for any one or more of the following:- indicating (e.g., implicitly or explicitly) whether one or more of the measurement values included in the measurement report are non-triggering measurement values;- indicating (e.g., implicitly or explicitly) whether one or more of the measurement values included in the measurement report are triggering measurement values;- reporting triggering measurement values;- reporting non-triggering measurement values; and- indicating (e.g., implicitly or explicitly) one of the at least one LTM candidate cell and / or a serving cell of the wireless device that is associated with a respective measurement value of the one or more measurement values.

[0082] In some examples, the one or more criteria may include reporting criteria (e.g., a reporting threshold or a reporting offset with respect to a measurement value for a resource serving the wireless device). If anon-triggering measurement value fulfils the reporting criteria (e.g., meets the reporting threshold or falls within the range defined by the reporting offset), the non-triggering measurement value may be considered eligible for inclusion in the measurement report and / or have a higher priority for inclusion in the measurement report over non-triggering measurement values that did not fulfil the reporting requirement.

[0083] The reporting criteria may be associated with a signal quality (e.g., Ll-RSRP) indicated by the non-triggering measurement value. In this case, non-triggering measurement values that meet signal quality criteria (e.g., high signal quality) may be included in the measurement report.

[0084] The reporting criteria may be defined relative to triggering criteria (e.g., a triggering threshold or a triggering offset with respect to a measurement value for a resource serving the wireless device) which, upon fulfilment by at least one of the measurement values,triggers transmission of the measurement report. This triggering criteria is discussed in more detail above, with reference to step 206.

[0085] The one or more criteria may indicate that triggering measurement values are to be prioritized for inclusion in the measurement report over non-triggering measurement values. In such cases, the wireless device may utilise the indicated instructions above when selecting whether certain triggering and non-triggering measurement values are to be included in the measurement report. For example, the wireless device may first select triggering measurements for inclusion in the measurement report according to the one or more criteria discussed above. Then, if the one or more criteria allow (e.g., are not violated as a result), the wireless device may select one or more non-triggering measurement values for inclusion in the measurement report. See embodiment B4 below for more details.

[0086] The one or more criteria may indicate that non-triggering measurement values of a first type are to be prioritized for inclusion in the measurement report over non-triggering measurement values of a second type). The non-triggering measurement values of the first type may be prioritized for inclusion in the measurement report over the non-triggering measurement values of the second type based on any one of more of:• the non-triggering measurement values of the first type indicating a higher signal quality (e.g., Ll-RSRP) than the non-triggering measurement values of the second type (e.g., based on the non-triggering measurement values of the first type having a higher ranking than non-triggering measurement values of the second type, wherein the ranking is based on indicated signal quality of the non-triggering measurement value);• an activation of a first TCI state(s) corresponding to the non-triggering measurement values of the first type and / or an activation of the second TCI state(s) corresponding to the non-triggering measurement values of the second type (e.g., based on the first TCI state(s) being activated and the second TCI state(s) not being activated); and• a synchronization state of a first resource corresponding to the non-triggering measurement value of the first type and / or a synchronization state of a second resource corresponding to the non-triggering measurement value of the second type (e.g., based on the first resource being in uplink synchronization and the second resource not being in uplink synchronization).

[0087] It should be noted that the one or more configurations may be transmitted to the wireless device, from the network node, in the same message (e.g., in an RRC message or any other suitable message). Alternatively, the one or more configurations may be included in a plurality of messages sent from the network node. For example, individual configurations (or part thereof) may be included in respective ones of the plurality of messages. In other examples, more than one configuration (or parts thereof) may be included in respective ones of the plurality of messages.

[0088] Transmission of the one or more configurations to the wireless device may cause the wireless device to select one or more measurement values for inclusion in a measurement report according to the reporting configuration (e.g., based on the priority of the one or more measurement values for inclusion in the measurement report).

[0089] At step 304, the method comprises receiving, from the wireless device, the measurement report responsive to the wireless device detecting, using measurement values (e.g., LI measurement values) obtained by the wireless device, an event (e.g., an LI event) that triggers transmission of the measurement report. The measurement report may comprise indications of one or more of the measurement values selected for inclusion in the measurement report according to the reporting configuration. It is noted that step 304 corresponds to step 208 in Figure 2.UE-related Embodiments

[0090] Features of the embodiments below may be incorporated into the methods of Figure 2 and 3.AL Methods at a User Equipment (UE), which is configured with at least a LTM candidate cell (e.g., one or more LTM cells), and a LTM measurement resource configuration which indicates a set of reference signals to measure (e.g., each indicated by an SSB index and its associated LTM candidate cell ID) and an LTM reporting configuration configuring one or more LI events (or in more general terms, an event-triggered LTM measurement report), each of them with one or more conditions to be evaluated by the UE, the method comprising:• Performing measurements on one or more beams i.e., on reference signals (e.g., SSB(s) of an LTM candidate cell and / or of a serving cell) according to the measurement configuration that the UE receives.• When conditions are fulfilled for an event, determining to transmit an event-triggered LTM measurement report according to one or more (but not limited to) of the following options:olf the measurement quantity measured on the reference signals (which may be considered beams) which have not fulfilled an event condition, e.g., Ll-RSRP, is above a thresholdo And if less than N triggered beams have been included in the measurement report and this means that there is room to include more beams, wherein / Vis a maximum number of beams the UE is to report.o Transmitting an event-triggered measurement report by including a sub-set of beams which have not fulfilled any event condition(s).A2. The method in Al wherein each non-triggered beam to be included is explicitly indicated in the event-triggered measurement report.• In one example, for each beam included in the report there a field which indicates its status. This means that the field may be a bit which is set to 1 to indicate that this beam is a beam which has not fulfilled any event condition and 0 to indicate that this beam has fulfilled an event condition. The value of the field could be also something like “event fulfilled”, “event not fulfilled”, “yes”, “no” and any other time which help to distinguish a beam which has fulfilled an event condition from the one that it didn’t.• In one option, the beams which have not fulfilled any event condition are included in a particular location of the report (e.g., a specific set of OCTETS in the MAC CE of the report in which the UE includes information on the non-triggered beams, like a measurement information and an identification of the beam). For instance, if the report can include maximum N beams, the beams which did not fulfilled any event conditions are included starting from position 1 to N / 2 or from position N / 2 to N. A3. The method in Al or A2, wherein the report configuration received by the UE may include a “secondary threshold” or “secondary offset” based on which the UE determines the inclusion in the event-triggered measurement report of the beams which have not fulfilled the event condition(s).• In one option, the threshold indicates that if the measurement quantity measured on beams which have not fulfilled the event condition(s) is above the threshold, then thisbeam which have not fulfilled event condition(s) should be included in the report. In other words, UE includes a secondary “detection” threshold value to be applied, such that the secondary “detection” threshold is different from the threshold defined for the LTM event. For example, for the event LTM4, the threshold for triggering the event condition is above -90dBm RSRP but the secondary “detection” threshold is -HOBm RSRP.• In one option, the threshold indicates that if the measurement quantity measured on beams which have not fulfilled the event condition(s) is below the threshold, then the beams which have not fulfilled event condition(s) should be included in the report.• In another option, the threshold is a structure which include two different field (e.g., threshold! and threshold ) and this indicates that if the measurement quantity measured on the beams which have not fulfilled event condition(s) is above the threshold 1 and below the threshold?, then the beams which have not fulfilled event condition(s) should be included in the report.• In another option, the received reporting configuration at the UE includes a secondary “offset” value to be applied, such that the secondary “offset” is different from the offset for the LTM event, e.g., for the event LTM3, the offset for triggering the event condition is above 3dB RSRP difference between the LTM candidate cell beam and the serving beam but the beams which have not fulfilled the event condition but are ?dB higher than the serving beam are reported.• In another option, the received reporting configuration at the UE includes a secondary “offset” value to be applied, such that the secondary “offset” is different from the offset for the LTM event. Such a secondary offset is used by the UE to determine which beams are to be included in the measurement report. In some embodiments, the UE includes only those beams that are within the secondary offset range from the strongest beam measurement on the corresponding frequency. In some other embodiments, the UE includes only those beams that are within the secondary offset range from the strongest beam measurement that has been included in the measurement report as part of the triggered beam / cell list.• Such a secondary threshold or secondary offset could be configured differently for different measurement objects i.e., if the UE is triggering a measurement report based on A3 like event (i.e., neighbor becomes offset better than the serving), then the UE has both the serving cell related beam measurements which could be on onefrequency and the neighbor cell related beam measurements which could be on another frequency. In such a scenario, the UE could use one secondary threshold or secondary offset to decide which non-triggered beams to include on the serving cell’s frequency and another secondary threshold or secondary offset to decide which nontriggered beams to include on the neighbor cell’s frequency.A4. The method in any one of Al to A3, wherein a UE, upon triggering the LTM measurement report, determines the triggered beams (i.e., triggered reference signal(s)) which fulfill the event (i.e., the condition associated to the event) and includes them in the measurement report (in the LTM measurement report, e.g., over a MAC CE), up to the maximum number of beams (e.g., parameter ‘TV’ configured at the UE by the network, in the reporting configuration based on which the UE has triggered the LTM measurement report). When the number of triggered beams does not exceed the value of ‘N’, the UE also includes non-triggered beams (i.e., one or more beam(s) not fulfilling the event).• In one option, that is also up to N.• In one option, the UE receives a separate indication regarding the inclusion of nontriggered beams such that the beams belong to one or more LTM candidate cell(s) which had triggered beams (i.e., triggered LTM candidate cell(s)). That would indicate to the network, in the report, more beams of the cells which are good candidates for an LTM Cell switch.• In another option, the UE receives a separate indication about the inclusion of nontriggered beams such that the beams belong to the other LTM cells which are not the triggered cells i.e., beam of LTM candidate cell(s) for which none of the beams triggered the event for that LTM measurement report. That would indicate to the network, in the report, cells which are not good candidates for an LTM Cell switch.• In another option, the UE receives a separate parameter / VI (i.e., not TV) indicating a maximum number of non-triggered beams to be reported.• In another option, the UE receives a separate parameter N2 (i.e., not TV) indicating a maximum number of non-triggered beams of non-triggered LTM candidate cells to be reported.• In another option, the UE receives a separate parameter TV3 (i.e., not TV) indicating a maximum number of non-triggered beams of triggered LTM candidate cells to bereported, such that one or more triggered beam(s) from the triggered LTM candidate cells are also included in the LI measurement report.• In another option, the non-triggered beam(s) are reported in the decreasing order of their measurement quality, i.e., if a given beam has higher RSRP / RSRQ / SINR than the other remaining non-fulfilling beam(s), it is prioritized for the reporting.• In one option, the UE explicitly receives an indication to include X beam(s) which have not fulfilled any event condition, on top of the N beams which have fulfilled the event condition(s).A5. The method in any one of Al to A4, wherein a UE receives, in an LTM reporting configuration (e.g., in an instance of the IE LTM-ReportConfig) an event configuration, a parameter N indicating a maximum number of beams to report, and a threshold. When the event is fulfilled, the UE includes in the LTM measurement report triggered by the fulfilled event the triggered beams up to the value N.• When there are more triggered beams than N, the UE ranks the triggered beams in terms of a measurement quantity (e.g., trigger quantity, LI RSPR, etc.) and includes the top N according to the rank. In other words, the UE includes the N strongest triggered beams according to the measurement quantity e.g., LI RSRP.• When there are less triggered beams than N the UE includes one or more remaining beams (non-triggered beam) up to N for which a measurement quantity (trigger quantity in the event configuration e.g., LI RSRP) is above the configured threshold. In this case, N is interpreted as the maximum number of beams to report, including both triggered and non-triggered, and regardless of which LTM candidate cell the beams are associated to.• In another option, the UE receives an indication to not include non-triggered beam(s) / reference signal(s) measurements, given that the number of beam(s) / reference signal(s) which fulfil the event condition(s) exceeds N, i.e., the maximum possible number of beam(s) / reference signal(s) within the MAC CE report.A6. The method in any one of Al to A5, wherein the UE is configured with a threshold and the number of beams X which have not fulfilled the event conditions and the UE reporting only the number Y of beams’ which have not fulfilled the event condition(s) and whose measurement quantity (e.g., measured RSRP) is above the configured threshold.• In one option, the number of reported beams Y which have not fulfilled the event condition is equal to X• In one option, the number of reported beams Y which have not fulfilled the event condition is less thanA7. The method in any one of Al to A6, wherein the UE is only reports on the non-triggered beams, whether the beams belong to the triggered LTM candidate cell or the non-triggered LTM candidate cell, given that the available UL grant for sending the LTM measurement report is large enough to send the non-triggered beams.A8. The method in any one of Al to A7, wherein the UE only indicates the number of nontriggered beam, such that the beams do not fulfill the event conditions, but the beams fulfill the “secondary threshold” or “secondary offset” criteria.• In one option, the number of the non-triggered beams is reported over the entire measurement resource configuration which is associated to the triggering event. • In another option, the number of the non-triggered beams is reported per each triggered and non-triggered LTM candidate cell.• In another option, the number of the non-triggered beams is reported only for the triggered or non-triggered LTM candidate cells.A9.

[0091] In one embodiment, for a given instance of LTM reporting configuration (configuring event triggered LTM measurement reporting, which may be simply called a reporting configuration), when the event triggered LTM measurement reporting is triggered, the UE determines one or more triggered cells to include in the LTM measurement report, up to a value of a first parameter e.g., nrOfReportedCells, wherein the triggered cells are among the LTM candidate cell(s) in the LTM resource configuration associated to the instance of LTM reporting configuration.• In one option, when the number of triggered cells is equal than the value of the first parameter, the UE includes them in the LTM measurement report.• In one option, when the number of triggered cells is lower than the value of the first parameter, the UE includes them in the LTM measurement report.oln one sub-option, after including the triggered cells (i.e. , LTM candidate cells for which beams fulfill the associated condition), the UE further includes one or more non-triggered cells.■ In one option, the UE includes one or more non-triggered cells together with the included triggered cells, so that the total number of included cells is up to the value of the first parameter.■ In one option, the UE includes the strongest non-triggered cells according to the same trigger quantity used for the triggered cells (e.g., LI RSRP), together with the included triggered cells, so that the total number of included cells is up to the value of the first parameter. This is important when the number of non-triggered cells (in the associated resource configuration), together with the included triggered cells exceeds the value of the first parameter.• In one option, when the number of triggered cells is higher than the value of the first parameter the UE includes the strongest triggered cells according to a trigger quantity (E.g. LI RSRP), up to the value of the first parameter.

[0092] In one embodiment, for a given instance of LTM reporting configuration (configuring event triggered LTM measurement reporting), when the event triggered LTM measurement reporting is triggered, the UE determines one or more non-triggered cells to include in the LTM measurement report, up to a value of a second parameter e.g.nrOfNonTriggeredCells, wherein the non-triggered cells are among the LTM candidate cell(s) in the LTM resource configuration associated to the instance of LTM reporting configuration.• In one option, when the number of non-triggered cells is lower or equal than the value of the second parameter, the UE includes them in the LTM measurement report.• In one option, when the number of non-triggered cells is higher than the value of the second parameter, the UE includes them in the LTM measurement report, the UE includes the strongest non-triggered cells according to a trigger quantity (e.g. LI RSRP), up to the value of the second parameter.• In one option, when the number of non-triggered cells is higher than the value of the second parameter, the UE includes them in the LTM measurement report, the UE includes the strongest non-triggered cells according to a trigger quantity (e.g. LI RSRP), up to the value of the second parameter, wherein the UE includes the cells for which the strongest beam is above a first threshold (i. e. , beams whose trigger quantity, e.g., LI RSRP; is above the threshold).

[0093] In one embodiment, for a given instance of LTM reporting configuration (configuring event triggered LTM measurement reporting), when the event triggered LTM measurement reporting is triggered, the UE determines one or more triggered cells to include in the LTM measurement report, up to a value of a first parameter e.g. nrOfReportedCells, wherein the triggered cells are among the LTM candidate cell(s) in the LTM resource configuration associated to the instance of LTM reporting configuration, AND the UE determines one or more non-triggered cells to include in the LTM measurement report, up to a value of a second parameter e.g. nrOfNonTriggeredCells, wherein the non-triggered cells are among the LTM candidate cell(s) in the LTM resource configuration associated to the instance of LTM reporting configuration.• In one option, when the number of triggered cells is equal than the value of the first parameter, the UE includes them in the LTM measurement report, and when the number of non-triggered cells is lower or equal than the value of the second parameter, the UE includes them in the LTM measurement report.• In one option, when the number of triggered cells is lower than the value of the first parameter, the UE includes them in the LTM measurement report and when the number of non-triggered cells is lower than the value of the second parameter, the UE includes them in the LTM measurement report.

[0094] In one embodiment, the UE indicates in the LTM measurement report that a cell is a non-triggered cell, e.g., using a flag or a tag in the report.Selecting the triggered and non-triggered beams to include

[0095] In one embodiment, for a given instance of LTM reporting configuration (configuring event triggered LTM measurement reporting, which may be simply called a reporting configuration), when the event triggered LTM measurement reporting is triggered, the UE determines one or more triggered beams of triggered cells to include in the LTM measurement report, up to a value of a third parameter e.g., nrOfReportedBeamsPerCell. When for each triggered cell included in the LTM measurement report, the number of triggered beams does not exceed the value of the third parameter, the UE further includes non-triggered beams up to the value of the third parameter for the included triggered cells.

[0096] According to a main embodiment of the method, the one or more parameters received by the UE, in the LTM reporting configuration, comprise at least one “secondary” threshold or offset value for selecting ‘good’ non-triggered beams so the UE includes nontriggered beams having a measurement quantity (e.g., LI RSRP) which is above the secondary threshold. Then, the UE includes the triggered beams up to another parameter defined as the maximum number of beams to include ( ’) and, when the number of triggered beams for that LTM measurement reporting is lower than ‘TV’, the UE further includes in the LTM measurement report one or more ’good’ non-triggered beams, up to W’.• In one option the parameter is a “secondary” threshold (or offset w.r.t the serving beam), wherein the UE includes the non-triggered beam when that is above that threshold.• In another option, the parameter is an indication indicating the UE to include nontriggered beams of triggered LTM candidate cells only. In other words, when the LI LTM measurement report is triggered, the UE first includes the triggered beams (i.e., one or more beams fulfilling the event). When the number of triggered beams (e.g., KI), of a triggered LTM cell, is smaller than the maximum allowed number of beams allowed to be included in the LI LTM measurement report (e.g., KKN), the UE includes one or more non-triggered beams of the triggered LTM candidate cell (i.e., an LTM candidate cell from which the beam has triggered the event) up to N.• In another option, the first parameter is the indication indicating the UE to include non-triggered beams of triggered LTM candidate cells only, and a second parameter isa “secondary” threshold (or offset w.r.t the serving beam). When the LI LTM measurement report is triggered, the UE first includes the triggered beams (i.e., one or more beams fulfilling the event). When the number of triggered beams (e.g., KI), of a triggered cell, is smaller than the maximum allowed number of beams allowed to be included in the LI LTM measurement report (e.g., K1<N), the UE includes one or more non-triggered beams of the triggered LTM candidate cell (i.e., an LTM candidate cell from which the beam has triggered the event) for which a measurement (e.g., Ll-RSRP) is above the threshold, up to N.• In another option, the parameter is an indication indicating the UE to include nontriggered beams of non-triggered LTM candidate cells. In other words, when the LI LTM measurement report is triggered, the UE first includes the triggered beams (i.e., one or more beams fulfilling the event). When the number of triggered beams (e.g., KI), of a triggered cell, is smaller than the maximum allowed number of beams allowed to be included in the LI LTM measurement report (e.g., K1<N), the UE includes one or more non-triggered beams of the triggered LTM candidate cell (i.e., an LTM candidate cell from which the beam has triggered the event) up to N. If there are still remaining beams which may be reported, the UE includes one or more non-triggered beams of non-triggered LTM candidate cell(s) (i.e., an LTM candidate cell from which the beam has triggered the event) up to N.• In another option, the parameter is an indication of a maximum number of nontriggered beams of a triggered LTM candidate cell the UE may include in the LI LTM measurement report.• In another option, the parameter is an indication of a maximum number of nontriggered beams of non-triggered LTM candidate cell(s) the UE may include in the LI measurement report.Network-related Embodiments

[0097] It is noted that features of the embodiments below may be incorporated into the methods of Figure 2 and 3.BL A method at a first network node e.g., a source gNB-DU, a source gNB-CU, a source gNB, to configure a UE with at least a LTM candidate cell (e.g., one or more LTM cells), and a LTM measurement resource configuration which indicates a set of reference signals to measure (e.g., each indicated by an SSB index and its associated LTM candidate cell ID) andan LTM reporting configuration configuring one or more LI events (or in more general terms, an event-triggered LTM measurement report), each of them with one or more conditions to be evaluated by the UE, the method comprising:• The UE performing measurements on one or more beams i.e., on reference signals (e.g., SSB(s) of an LTM candidate cell and / or of a serving cell) according to the measurement configuration that the UE is configured with.• When conditions are fulfilled for an event, configuring the UE to transmit an event- triggered LTM measurement report according to one or more (but not limited to) of the following options:olf the measurement quantity measured on the reference signals (which may be considered beams) which have not fulfilled an event condition, e.g., Ll-RSRP, is above a thresholdo And if less than N triggered beams are to be included in the measurement report and this means that there is room to include more beams, wherein / Vis a maximum number of beams the UE is to report.o Configuring the transmission of an event-triggered measurement report by including a sub-set of beams which have not fulfilled any event condition(s).B2. The method in Bl wherein the network configuration provided by the network node explicitly indicates the inclusion of non-triggered beams in the event-triggered measurement report.• In one example, for each beam included in the report there a field which indicates its status. This means that the field may be a bit which is set to 1 to indicate that this beam is a beam which has not fulfilled any event condition and 0 to indicate that this beam has fulfilled an event condition. The value of the field could be also something like “event fulfilled”, “event not fulfilled”, “yes”, “no” and any other time which help to distinguish a beam which has fulfilled an event condition from the one that it didn’t.• In one option, the beams which have not fulfilled any event condition are configured to be included in a particular location of the report (e.g., a specific set of OCTETS in the MAC CE of the report in which the UE includes information on the non-triggered beams, like a measurement information and an identification of the beam). For instance, if the report can include maximum N beams, the beams which did notfulfilled any event conditions are to be included starting from position 1 to N / 2 or from position N / 2 to N.B3. The method in Bl or B2, wherein the report configuration provided by the network may include a “secondary threshold” or “secondary offset” based on which the UE determines the inclusion in the event-triggered measurement report of the beams which have not fulfilled the event condition(s).• In one option, the threshold indicates that if the measurement quantity measured on beams which have not fulfilled the event condition(s) is above the threshold, then this beam which have not fulfilled event condition(s) should be included in the report. In other words, the network indicates to include a secondary “detection” threshold value to be applied, such that the secondary “detection” threshold is different from the threshold defined for the LTM event. For example, for the event LTM4, the threshold for triggering the event condition is above -90dBm RSRP but the secondary “detection” threshold is -1 lOBm RSRP.• In one option, the threshold indicates that if the measurement quantity measured on beams which have not fulfilled the event condition(s) is below the threshold, then the beams which have not fulfilled event condition(s) should be included in the report.• In another option, the configured threshold is a structure which includes two different field (e.g., threshold! and threshold2) and this indicates that if the measurement quantity measured on the beams which have not fulfilled event condition(s) is above the threshold 1 and below the threshold2, then the beams which have not fulfilled event condition(s) should be included in the report.• In another option, the reporting configuration provided by the network includes a secondary “offset” value to be applied, such that the secondary “offset” is different from the offset for the LTM event, e.g., for the event LTM3, the offset for triggering the event condition is above 3dB RSRP difference between the LTM candidate cell beam and the serving beam but the beams which have not fulfilled the event condition but are 2dB higher than the serving beam are reported.• In another option, the received reporting configuration at the UE includes a secondary “offset” value to be applied, such that the secondary “offset” is different from the offset for the LTM event. Such a secondary offset is used by the UE to determine which beams are to be included in the measurement report. In some embodiments, theUE includes only those beams that are within the secondary offset range from the strongest beam measurement on the corresponding frequency. In some other embodiments, the UE includes only those beams that are within the secondary offset range from the strongest beam measurement that has been included in the measurement report as part of the triggered beam / cell list.• Such a secondary threshold or secondary offset could be configured differently for different measurement objects i.e., if the UE is triggering a measurement report based on A3 like event (i.e., neighbor becomes offset better than the serving), then the UE has both the serving cell related beam measurements which could be on one frequency and the neighbor cell related beam measurements which could be on another frequency. In such a scenario, the UE could use one secondary threshold or secondary offset to decide which non-triggered beams to include on the serving cell’s frequency and another secondary threshold or secondary offset to decide which nontriggered beams to include on the neighbor cell’s frequency.B4. The method in any one of Bl to B3, wherein the network configures a UE to include the triggered beams (i.e., triggered reference signal(s)), which fulfill the event (i.e., the condition associated to the event) in the measurement report (in the LTM measurement report, e.g., over a MAC CE), up to the maximum number of beams (e.g., parameter ‘TV’ configured at the UE by the network, in the reporting configuration. When the number of triggered beams does not exceed the value of ‘N’, the network configures the UE to include non-triggered beams (i.e., one or more beam(s) not fulfilling the event).• In one option, that is also up to N.• In one option, the network sends a separate indication to the UE regarding the inclusion of non-triggered beams such that the beams belong to one or more LTM candidate cell(s) which had triggered beams (i.e., triggered LTM candidate cell(s)).• In another option, the network sends a separate indication to the UE about the inclusion of non-triggered beams such that the beams belong to the other LTM cells which are not the triggered cells i.e., beam of LTM candidate cell(s) for which none of the beams triggered the event for that LTM measurement report.• In another option, the network configures the UE with a separate parameter / VI (i.e., not TV) indicating a maximum number of non-triggered beams to be reported.• In another option, the network configures the UE with a separate parameter N2 (i.e., not TV) indicating a maximum number of non-triggered beams of non-triggered LTM candidate cells to be reported.• In another option, the network configures the UE with a separate parameter N3 (i.e., not TV) indicating a maximum number of non-triggered beams of triggered LTM candidate cells to be reported, such that one or more triggered beam(s) from the triggered LTM candidate cells are also included in the LI measurement report.• In another option, the network configures to report the non-triggered beam(s) in the decreasing order of their measurement quality, i.e., if a given beam has higher RSRP / RSRQ / SINR than the other remaining non-fulfilling beam(s), it is prioritized for the reporting.• In one option, the network explicitly sends an indication to the UE for including X beam(s) which have not fulfilled any event condition, on top of the N beams which have fulfilled the event condition(s).B5. The method in any one of Bl to B4, wherein the network configures the UE, in an LTM reporting configuration (e.g., in an instance of the IE LTM-ReportConfig) an event configuration, a parameter TV indicating a maximum number of beams to report, and a threshold. When the event is fulfilled, the network configures the UE to include up to the value TV in the LTM measurement report triggered by the fulfilled event the triggered beams.• When there are more triggered beams than TV, the network indicates to rank the triggered beams in terms of a measurement quantity (e.g., trigger quantity, LI RSPR, etc.) and include the top TV beams according to the rank. In other words, the UE is configured to include the TV strongest triggered beams according to the measurement quantity e.g., LI RSRP.• When there are less triggered beams than TV the network indicates to include one or more remaining beams (non-triggered beam) up to TV for which a measurement quantity (trigger quantity in the event configuration e.g., LI RSRP) is above the configured threshold. In this case, TV is interpreted as the maximum number of beams to be reported, including both triggered and non-triggered, and regardless of which LTM candidate cell the beams are associated to.• In another option, the network sends an indication to the UE to not include nontriggered beam(s) / reference signal(s) measurements, given that the number ofbeam(s) / reference signal(s) which fulfil the event condition(s) exceeds N, i.e., the maximum possible number of beam(s) / reference signal(s) within the MAC CE report.B6. The method in any one of Bl to B5, wherein the network configures the UE with a threshold and the number of beams X which have not fulfilled the event conditions and the UE reporting only the number Y of beams’ which have not fulfilled the event condition(s) and whose measurement quantity (e.g., measured RSRP) is above the configured threshold.• In one option, the number of reported beams Y which have not fulfilled the event condition is equal to X• In one option, the number of reported beams Y which have not fulfilled the event condition is less than AB7. The method in any one of Bl to B6, wherein the network configures the UE to only report on the non-triggered beams, whether the beams belong to the triggered LTM candidate cell or the non-triggered LTM candidate cell, given that the available UL grant for sending the LTM measurement report is large enough to send the non-triggered beams.B8. The method in any one of Bl to B7, wherein the network configures the UE to indicate the number of non-triggered beam only, such that the beams do not fulfill the event conditions, but the beams fulfill the “secondary threshold” or “secondary offset” criteria.• In one option, the number of the non-triggered beams to be reported is configured over the entire measurement resource configuration which is associated to the triggering event.• In another option, the number of the non-triggered beams to be reported is configured per each triggered and non-triggered LTM candidate cell.• In another option, the number of the non-triggered beams to be reported is configured only for the triggered or non-triggered LTM candidate cells.

[0098] Figure 4 shows an example of a communication system 400 in accordance with some embodiments.

[0099] In the example, the communication system 400 includes a telecommunications network 402 that includes an access network 404, such as a radio access network (RAN), anda core network 406, which includes one or more core network nodes 408. The access network 404 includes one or more access network nodes or base stations of various types, access network nodes 410A and 410B are depicted (which may be collectively referred to as network nodes 410), or any other similar 3rdGeneration Partnership Project (3GPP) access nodes or non-3GPP access points (APs). Some embodiments of the access network 404 may include more than one access network technology. The network nodes 410 of access network 404 facilitate direct or indirect connection of wireless devices, also referred to as user equipments (UEs), such as by connecting UEs 412A, 412B, 412C, and 412D (one or more of which may be generally referred to as UEs 412) to the core network 406 over one or more wireless connections.

[0100] Moreover, 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 telecommunications network 402 includes one or more Open-RAN (ORAN) network nodes. An ORAN network node is a network node in the telecommunications network 402 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 network nodes to implement one or more functionalities of any network node in the telecommunications network 402, including one or more access network nodes 410 and / or core network nodes 408.

[0101] Examples of an ORAN network node include an open radio unit (O-RU), an open distributed unit (O-DU), an open central unit (O-CU), including an O-CU control plane (O-CU-CP) or an O-CU 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). An ORAN network node may support a specification by, for example, supporting an interface defined by the ORAN specification, such as an Al, Fl, Wl, El, E2, X2, Xn interface, an open fronthaul user plane interface, or an open fronthaul management plane interface. Moreover, an ORAN network 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 andOrchestration Framework via an 0-2 interface defined by the 0-RAN Alliance or comparable technologies.

[0102] The network nodes 410 facilitate direct or indirect connection of one or more UEs 412 to the core network 406 over one or more wireless connections. 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 400 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 400 may include and / or interface with any type of communication, telecommunication, data, cellular, radio network, and / or other similar type of system.

[0103] The UEs 412 may be any of a wide variety of communication devices, including wireless devices arranged, configured, and / or operable to communicate wirelessly with the network nodes 410 and other communication devices. Similarly, the network nodes 408, 410 are arranged, capable, configured, and / or operable to communicate directly or indirectly (e.g., via other devices of telecommunications network 402) with the UEs 412 and / or with other network nodes or equipment in the telecommunications network 402 to enable and / or provide network access, such as wireless network access, and / or to perform other functions, such as administration in the telecommunications network 402. More specifically, UEs 412 may send messages, data, and / or other signals to network nodes 408, 410 or other elements of the telecommunications network 402 by transmitting such signals to the relevant device directly without the signals passing through any intervening devices or by transmitting such signals to the relevant device indirectly through an intervening device (or multiple intervening devices) that then transmit the signal to the relevant device. Similarly, network nodes 408, 410 may send messages, data, and other signals to UEs 4122, other network nodes 408, 410, and other devices in telecommunications network 402 directly or indirectly. As one specific example, a core network node 108 may transmit a particular message to a UE 412 by transmitting the message to an access network node 410 that will then transmit the message to the intended UE 412. Similarly, a core network node 108 may receive a particular message from a UE 412 by receiving the message from an access network node 410 that itself received the message from the UE 412.

[0104] In the depicted example, the core network 406 connects elements of the access network 404 (e.g., one or more of the network nodes 410) to one or more host computing systems, such as host 416. 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 406 includes one or more core network nodes (e.g., core network node 408) of various types, one or more of which may be generally referred to as network nodes 408. Network nodes 408 are structured with hardware and software components. Features of these components may be substantially similar to those described with respect to the UEs, access network nodes, and / or hosts, such that the descriptions thereof are generally applicable to the corresponding components of the core network node 408. Example core network nodes provide 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 De-concealing function (SIDF), Unified Data Management (UDM), Security Edge Protection Proxy (SEPP), Network Exposure Function (NEF), and / or a User Plane Function (UPF).

[0105] The host 416 may be under the ownership or control of a service provider other than an operator or provider of the access network 404 and / or the telecommunications network 402. The host 416 may be operated by the service provider or on behalf of the service provider. The host 416 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.

[0106] As a whole, the communication system 400 of Figure 4 enables connectivity between the UEs, network nodes, and hosts. In that sense, the communication system 400 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 (Wi-Fi); and / or any other appropriate wireless communication standard, such as the Worldwide Interoperability for Microwave Access (Wi-Max), Bluetooth, Z-Wave, Near Field Communication (NFC) ZigBee, Li-Fi, and / or any low-power wide-area network (LPWAN) standards such as LoRa and Sigfox. Moreover, the communication system 400 may be configured to support multiple different standards, protocols, or other rule sets, with individual components supporting all of the relevant rule sets or with different components or sub-systems within the communication system 400 supporting different standards, protocols, or rule sets.

[0107] As one example, in certain embodiments, access network 404 may contain some access network nodes 410 that support 3GPP radio access technologies (RAT), such as LTE or NR, while other access network nodes 410 support (or the same access network nodes 410 additionally support) non-3GPP RATs, such as Wi-Fi or a proprietary RAT. As another example, telecommunications network 402 may support multiple generations of related communication standards (e.g., 4G and 5G 3GPP communication standards) and, as a result, may include an access network 104 and / or a core network 106 that supports multiple different standard generations or may include multiple access networks 104 and / or multiple core networks 106 with individual networks 104, 106 supporting different standard generations.

[0108] Telecommunications network 402 may support network slicing to provide different logical networks to different devices that are connected to the telecommunications network 402. For example, the telecommunications network 402 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.

[0109] In some examples, one or more of the UEs 412 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 404 on a predetermined schedule, when triggered by an internal or external event, or in response to requests from the access network 404. 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).

[0110] In the example, the hub 414 communicates with the access network 404 to facilitate indirect communication between one or more UEs (e.g., UE 412C and / or 412D) and network nodes (e.g., network node 410B). In some examples, the hub 414 may be a controller, router, content source and analytics, or any of the other communication devices described hereinregarding UEs. For example, the hub 414 may be a broadband router enabling access to the core network 406 for the UEs. As another example, the hub 414 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 410, or by executable code, script, process, or other instructions in the hub 414.

[0111] As another example, the hub 414 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 414 may be a content source. For example, for a UE that is a VR headset, display, loudspeaker or other media delivery device, the hub 414 may retrieve VR assets, video, audio, or other media or data related to sensory information via a network node, which the hub 414 then provides to the UE either directly, after performing local processing, and / or after adding additional local content. In still another example, the hub 414 acts as a proxy server or orchestrator for the UEs, in particular if one or more of the UEs are low energy loT devices.

[0112] The hub 414 may have a constant / persistent or intermittent connection to the network node 410B. The hub 414 may also allow for a different communication scheme and / or schedule between the hub 414 and UEs (e.g., UE 412C and / or 412D), and between the hub 414 and the core network 406. In other examples, the hub 414 is connected to the core network 406 and / or one or more UEs via a wired connection. Moreover, the hub 414 may be configured to connect to an M2M service provider over the access network 404 and / or to another UE over a direct connection. In some scenarios, UEs may establish a wireless connection with the network nodes 410 while still connected via the hub 414 via a wired or wireless connection. In some embodiments, the hub 414 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 410B. In other embodiments, the hub 414 may be a non-dedicated hub - that is, a device which is capable of operating to route communications between the UEs and network node 410B, but which is additionally capable of operating as a communication start and / or end point for certain data channels.

[0113] Figure 5 is another example of a communication system 500 according to some embodiments. As used herein, the communication system 500 includes multiple access points (APs) 510 (with four exemplary APs 510A, 510B, 510C, and 510D being depicted) and multiple wireless devices, referred to in the context of communication system 500 as stations (STAs) 512 (referred to individually as STA 512A, STA 512B, STA 512C, STA 512D, andSTA 512E). STA 512A is served by AP 510A in a first basic service set (BSS) 520A. STA 510B and STA 510C are served by AP 510B in a second BSS, BSS 520B. STA 512D is served by AP 510C in a third BSS, BSS 520C. STA 512E is served by AP 510D in a fourth BSS, BSS 520D. Stations 512 may be non-AP STAs and correspond to various kinds of wireless devices, for example, user terminals, such as mobile or stationary computing devices like smartphones, laptop computers, desktop computers, tablet computers, gaming devices, head-mounted displays (HMDs) for Augmented Reality (AR) or Virtual Reality (VR), or the like. Further, stations 512 could, for example, correspond to other kinds of equipment like smart home devices, printers, multimedia devices, data storage devices, or the like.

[0114] Each of STAs 512 may connect through a radio link to one of APs 510. For example, depending on location or channel conditions experienced by a given STA 512, the STA may select an appropriate AP and BSS for establishing the radio link. The radio link may be based on one or more orthogonal frequency-division multiplexing (OFDM) carriers from a frequency spectrum that is shared on the basis of a contention-based mechanism, e.g., an unlicensed or license exempt band like 2.4 GHz Industrial, Scientific, and Medical (ISM) band, the 5 GHz band, the 6 GHz band, or the 60 GHz band.

[0115] Each AP 510 may provide data connectivity to STAs 512 connected to a particular AP 510. As illustrated, APs 510 may be connected to adatanetwork 530. In this way, APs 510 may also provide data connectivity between STAs 512 and other entities, e.g., to one or more servers, service providers, data sources, data sinks, user terminals, or the like. Accordingly, the radio link established between a given STA 512 and its serving AP 510 may be used for providing various kinds of services to STA 512, e.g., a voice service, a multimedia service, or other data service. Such services may be based on applications that are executed on STA 512 and / or on a device linked to STA 512. By way of example, Figure 5 illustrates an application service platform 532 provided in data network 530. The application(s) executed on STA 512 and / or on one or more other devices linked to STA 512 may use the radio link for data communication with one or more other STA 512 and / or the application service platform 532, thereby enabling utilization of the corresponding service(s) at STA 512.

[0116] Figure 6 shows a wireless device 600, which may be configured to operate in communication system 400 of Figure 4 or in communication system 500 of Figure 5. The wireless device 600 may be alternatively referred to as a UE 600, like a UE 412 within the context of communication system 400, or as a station (STA) 600 or as a non-access-point station (non-AP STA) 600, like a STA 512 within the context of the communication system500, in accordance with respective embodiments.

In other examples, wireless device 600 may not necessarily have a user in the sense of a human user who owns and / or operates the relevant device. Instead, wireless device 600 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, wireless device 600 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).

[0118] In particular embodiments, wireless device 600 includes processing circuitry 602 that is operatively coupled via a bus 604 to an input / output interface 606, a power source 608, a memory 610, a communication interface 612, and / or any other component, or any combination thereof. Certain embodiments of wireless device 600 may include all or a subset of the components shown in Figure 6. The level of integration between the components may vary from one embodiment of wireless device 600 to another. In general, in a particular embodiment of wireless device 600, processing circuitry 602, input / output interface 606, power source 608, memory 610, and communication interface 612 may, in whole or in part, represent or include physical components common to or shared by one or more of the other elements of wireless device 600. Further, certain embodiments of wireless devices 600 may contain multiple instances of a component, such as multiple processors, memories, transceivers, transmitters, receivers, etc.

[0119] The processing circuitry 602 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 610.

For example, the processing circuitry 602 may include multiple central processing units (CPUs). The processing circuitry 602 may be configured to cause the wireless device 600 to perform the methods as described with reference to Figure 2.

[0120] In the example, the input / output interface 606 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 wireless device 600. 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.

[0121] In some embodiments, the power source 608 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 to supply power to circuitry or to charge an associated battery. The power source 608 may further include power circuitry for delivering power from the power source 608 itself, and / or an external power source, to the various parts of wireless device 600 via input circuitry or an interface such as an electrical power cable. Power source 608 may perform any formatting, converting, or other modification to make accessible power suitable for the respective components of the wireless device 600 to which power is supplied.

[0122] The memory 610 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 610 includes one or more programs 614, such as an operating system, web browser application, a widget, gadget engine, or other application, and corresponding data 616. The memory 610 may store, for use by wireless device 600, any of a variety of various operating systems or combinations of operating systems.

[0123] The memory 610 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 (eUICC), integrated UICC (iUICC) or a removable UICC commonly known as ‘SIM card.’ The memory 610 may allow wireless device 600 to access instructions, 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 610, which may be or comprise a device-readable storage medium.

[0124] The processing circuitry 602 may be configured to communicate with an access network or other network via or using the communication interface 612. The communication interface 612 may comprise one or more communication subsystems and may include or be communicatively coupled to an antenna 622. The communication interface 612 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 wireless device or a network node in an access network). Each transceiver may include a transmitter 618 and / or a receiver 620 appropriate to provide network communications (e.g., optical, electrical, frequency allocations, and so forth). Moreover, the transmitter 618 andreceiver 620 may be coupled to one or more antennas (e.g., antenna 622) and may share circuit components, software or firmware, or alternatively be implemented separately.

[0125] In the illustrated embodiment, communication functions of the communication interface 612 may include cellular communication, Wi-Fi communication (e.g., according to an IEEE 802.11 family standard), 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 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 / intemet protocol (TCP / IP), synchronous optical networking (SONET), Asynchronous Transfer Mode (ATM), QUIC, Hypertext Transfer Protocol (HTTP), and so forth.

[0126] In particular embodiments, wireless device 600 may provide an output of data captured via a sensor, through its communication interface 612, via a wireless connection to a network node, and / or in any appropriate manner. Data captured by sensors of a wireless device 600 can be communicated through a wireless connection to a network node via another wireless device 600. In particular embodiments, such 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).

[0127] As another example, wireless device 600 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, wireless device 600 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.

[0128] Wireless device 600, 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, 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 connectedrefrigerator 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. In particular embodiments, wireless device 600 represents an loT device that 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 example embodiment of wireless device 600 shown in Figure 6.

[0129] As yet another specific example, in an loT scenario, wireless device 600 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 wireless device and / or a network node. Wireless device 600 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, wireless device 600 may implement the 3GPP NB-IoT standard. In other scenarios, wireless device 600 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.

[0130] In practice, any number of wireless devices 600 may be used together with respect to a single use case. For example, a first wireless device 600 might be or be integrated in a drone and provide the drone’s speed information (obtained through a speed sensor) to a second wireless device 600 that is a remote controller operating the drone. When a user makes changes from the remote controller, the first wireless device 600 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 wireless device 600 can also include more than one of the functionalities described above. For example, wireless device 600 might comprise the sensor and the actuator, and handle communication of data for both the speed sensor and the actuators.

[0131] Figure 7 shows a network node 700 in accordance with some embodiments. As used herein, network node refers to equipment capable, configured, arranged and / or operableto communicate directly or indirectly with a UE and / or with other network nodes or equipment, in a telecommunications network. In accordance with respective embodiments, network node 700 may be configured to operate in communication system 400 of Figure 4, like network nodes 408 or 410, or in communication system 500 of Figure 5, like an AP 510 or a station 512. 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).

[0132] Network nodes 700 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. Network node 700 may be a relay node or a relay donor node controlling a relay. Network nodes 700 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).

[0133] Other examples of network nodes 700 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).

[0134] In particular embodiments, network node 700 includes a processing circuitry 702, a memory 704, a communication interface 706, and a power source 708. In general, in a particular embodiment of network node 700, processing circuitry 702, memory 704, communication interface 706, and power source 708 may, in whole or in part, represent or include physical components common to or shared by one or more of the other elements of network node 700.

[0135] The network node 700 may be composed of multiple distinct network entities (e.g. , a NodeB entity and a RNC entity, or a BTS entity and a BSC entity, etc.), which may each have or utilize their own respective physical components. In certain scenarios in which thenetwork node 700 comprises multiple such entities (e.g., BTS and BSC), one or more of the separate entities 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 700 may be configured to support multiple radio access technologies (RATs). In such embodiments, some components may be duplicated (e.g., separate memories 704 or portions of memory 704 for different RATs) and some components may be reused (e.g., a same antenna 710 may be shared by different RATs). The network node 700 may also include multiple sets of the various illustrated components for different wireless technologies integrated into network node 700, for example GSM, WCDMA, LTE, NR, Wi-Fi (e.g., according to an IEEE 802.11 family standard), 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 700.

[0136] The processing circuitry 702 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 components, such as the memory 704, to provide network node 700 functionality. For example, the processing circuitry 702 may be configured to cause the network node 700 to perform the methods as described with reference to Figure 3.

[0137] In some embodiments, the processing circuitry 702 includes a system on a chip (SOC). In some embodiments, the processing circuitry 702 includes one or more of radio frequency (RF) transceiver circuitry 712 and baseband processing circuitry 714. In some embodiments, the RF transceiver circuitry 712 and the baseband processing circuitry 714 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 712 and baseband processing circuitry 714 may be on the same chip or set of chips, boards, or units.

The memory 704 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 702 and utilized by the network node 700. The memory 704 may be used to store any calculations made by the processing circuitry 702 and / or any data received via the communication interface 706. In some embodiments, the processing circuitry 702 and memory 704 is integrated.

[0139] The communication interface 706 is used in wired or wireless communication of signaling and / or data with UEs, other network nodes, and / or any other network equipment. In the illustrated embodiment, communication interface 706 comprises port(s) / terminal(s) 716 to send and receive data, for example to and from a network over a wired connection. In particular embodiments, network node 600 may be capable of wireless communication and communication interface 706 may also include radio front-end circuitry 718 that may be coupled to, or in certain embodiments a part of, an antenna 710. Particular embodiments of radio front-end circuitry 718 include filter(s) 720 and amplifier(s) 722. The radio front-end circuitry 718 may be connected to an antenna 710 and processing circuitry 702. The radio frontend circuitry may be configured to condition signals communicated between antenna 710 and processing circuitry 702. The radio front-end circuitry 718 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 718 may convert the digital data into a radio signal(s) having the appropriate channel and bandwidth parameters using a combination of filters 720 and / or amplifiers 722. The radio signal(s) may then be transmitted via the antenna 710. Similarly, when receiving data, the antenna 710 may collect radio signals which are then converted into digital data by the radio front-end circuitry 718. The digital data may be passed to the processing circuitry 702. In other embodiments, the communication interface may comprise different components and / or different combinations of components.

[0140] In certain alternative embodiments, network node 700 may be capable of wireless communication but does not include separate radio front-end circuitry 718, instead, the processing circuitry 702 includes radio front-end circuitry and is connected to the antenna 710. Similarly, in some embodiments, all or some of the RF transceiver circuitry 712 is part of the communication interface 706. In still other embodiments, the communication interface 706 includes one or more ports or terminals 716, the radio front-end circuitry 718, and the RF transceiver circuitry 712, as part of a radio unit (not shown), and the communication interface706 communicates with the baseband processing circuitry 714, which is part of a digital unit (not shown).

[0141] The antenna 710 may include one or more antennas, or antenna arrays, configured to send and / or receive wireless signals. The antenna 710 may be coupled to the radio front-end circuitry 718 and may be any type of antenna capable of transmitting and receiving data and / or signals wirelessly. In certain embodiments, the antenna 710 is separate from the network node 700 and connectable to the network node 700 through one or more interfaces or ports.

[0142] The antenna 710, communication interface 706, and / or the processing circuitry 702 may be configured to perform some or all of the receiving operations and / or obtaining operations described herein as being performed by the network node 700. Any information, data and / or signals may be received from a UE, another network node and / or any other network equipment. Similarly, the antenna 710, the communication interface 706, and / or the processing circuitry 702 may be configured to perform some or all of the transmitting or sending operations described herein as being performed by the network node 700. Any information, data and / or signals may be transmitted to a UE, another network node and / or any other network equipment.

[0143] The power source 708 provides power to the various components of network node 700 in a form suitable for the respective components (e.g., at a voltage and current level needed for each respective component). The power source 708 may further comprise, or be coupled to, power management circuitry to supply the components of the network node 700 with power for performing the functionality described herein. For example, the network node 700 may be connectable to an external power source (e.g., the power grid, an electricity outlet) via an input circuitry or interface such as an electrical cable, whereby the external power source supplies power to power circuitry of the power source 708. As a further example, the power source 708 may comprise a source of power in the form of a battery or battery pack which is connected to, or integrated in, power circuitry. The battery may provide backup power should the external power source fail.

[0144] Embodiments of the network node 700 may include additional components beyond those shown in Figure 7 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 700 may include user interface equipment to allow input of information into the network node 700 and to allow output of information from the network node 700. This may allow a user to perform diagnostic, maintenance, repair, and other administrative functions for the network node 700.

[0145] Figure 8 is a block diagram illustrating a virtualization environment 800 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 800 hosted by one or more of hardware nodes, such as a hardware computing device that operates as an access network node, UE, core network node, or host. Further, in embodiments in which a 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 800 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.

[0147] Hardware 804 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 806 (also referred to as hypervisors or virtual machine monitors (VMMs)), provide VM 808A and VM 808B (which may be collectively referred to as VMs 808), and / or perform any of the functions, features and / or benefits described in relation with some embodiments described herein. The virtualization layer 806 may present a virtual operating platform that appears like networking hardware to one or more of the VMs 808.

[0148] The VMs 808 comprise virtual processing, virtual memory, virtual networking or interface and virtual storage, and may be run by virtualization layer 806. Different embodiments of the instance of a virtual appliance 802 may be implemented on one or more of VMs 808, 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 maybe 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.

[0149] In the context of NFV, each of the VMs 808 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 808, and that part of hardware 804 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 of the VMs 808 on top of the hardware 804 and corresponds to an application 802.

[0150] Hardware 804 may be implemented in a standalone network node with generic or specific components. Hardware 804 may implement some functions via virtualization. Alternatively, hardware 804 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 810, which, among others, oversees lifecycle management of applications 802. In some embodiments, hardware 804 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 812 which may alternatively be used for communication between hardware nodes and radio units.
