Description

USER EQUIPMENT AND METHOD FOR SELECTING AMONG MORE THAN ONE TRIGGERED PCELLS AND PSCELLS FOR CONDITIONAL HANDOVERTECHNICAL FIELDThe present disclosure relates to wireless communication systems, and in particular, to selecting cells during handover in wireless communication systems.BACKGROUNDIn a typical wireless communication network, wireless devices, also known as wireless communication devices, mobile stations, stations (STA) and / or User Equipment (UE), communicate via a Wide Area Network or a Local Area Network such as a Wi-Fi network or a cellular network comprising a Radio Access Network (RAN) part and a Core Network (CN) part. The RAN covers a geographical area which is divided into service areas or cell areas, which may also be referred to as a beam or a beam group, with each service area or cell area being served by a radio network node such as a radio access node e.g., a Wi-Fi access point, a Base Station (BS) or a radio base station (RBS), which in some networks may also be denoted, for example, a Base Station (BS), a NodeB, eNodeB (eNB), or gNodeB (gNB) as denoted in Fifth Generation (5G) telecommunications. A service area or cell area is a geographical area where radio coverage is provided by the radio network node. The radio network node communicates over an air interface operating on a radio frequency with the wireless devices within the range of the radio network node.3rd Generation Partnership Project (3GPP) is the standardization body for specifying the standards for the cellular system evolution, e.g., including 3G, 4G, 5G and the future evolutions. Specifications for Evolved Universal Terrestrial Radio Access (E- UTRA) and Evolved Packet System (EPS) have been completed within the 3GPP. In 4G also called a Fourth Generation (4G) network, EPS is core network and E-UTRA is radio access network. In 5G, 5GC is core network, NR is radio access network. As a continued network evolution, the new release of 3GPP specifies a 5G network also referred to as 5G New Radio (NR) and 5G Core (5GC).Frequency bands for 5G NR are being separated into two different frequency ranges, Frequency Range 1 (FR1) and Frequency Range 2 (FR2). FR1 comprises sub-6 GHz frequency bands. Some of these bands are bands traditionally used by legacy standards but have been extended to cover potential new spectrum offerings from 410 MHz to 7125 MHz. FR2 comprises frequency bands from 24.25 GHz to 52.6 GHz. Bands in this millimeter wave range have shorter range but higher available bandwidth than bands in the FR1.Multi-antenna techniques may significantly increase the data rates and reliability of a wireless communication system. For a wireless connection between a single user, such as UE, and a base station (BS), the performance is in particular improved if both the transmitter and the receiver are equipped with multiple antennas, which results in a Multiple-Input Multiple-Output (MIMO) communication channel. This may be referred to as Single-User (SU)-MIMO. In the scenario where MIMO techniques is used for the wireless connection between multiple users and the base station, MIMO enables the users to communicate with the base station simultaneously using the same time-frequency resources by spatially separating the users, which increases further the cell capacity. This may be referred to as Multi-User (MU)-MIMO. Note that MU-MIMO may benefit when each UE only has one antenna. The cell capacity can be increased linearly with respect to the number of antennas at the BS side. Due to that, more and more antennas are employed in BS. Such systems and / or related techniques are commonly referred to as massive MIMO.Conditional Handover (CHO)In rel-16 CHO was standardized. In CHO, the UE is configured with execution conditions and handover target configurations. The UE monitors the execution conditions and when the conditions are fulfilled, the UE applies the configuration of the target cell. The target configuration was prepared in advance, which makes the execution of the handover faster and with less risk of failures. When the UE executes the CHO or a regular handover, all (other) conditional reconfigurations are released. Figure 1a shows a signaling diagram of a CHO execution.Conditional Primary Secondary Cell (PSCell) Change (CPC)A solution for CPC procedure was also standardized in 3GPP Rel-16. Therein a UE operating in Multi-Radio Dual Connectivity (MR-DC) receives in a conditional reconfiguration one or multiple Radio Resource Control (RRC) Reconfigurations, e.g., an RRCReconfiguration message, containing a Secondary Cell Group (SCG) configuration, e.g., a secondaryCellGroup of Information Element (IE) CellGroupConfig, with a reconfigurationWithSync that is stored and associated with an execution condition, e.g., a condition like an A3 / A5 event configuration, so that one of the stored messages is only applied upon the fulfillment of the execution condition e.g., associated with the serving PSCell, upon which the UE would perform PSCell change, e.g., in case it finds a neighbour cell that is better than the current special cell (SpCell) of the SCG. Only intra-Secondary Node (SN) CPC without Master Node (MN) involvement is standardized in 3GPP Rel-16, i.e., for cases where the (candidate) target PSCells are located in the current serving SN.Similar to conditional handover, in case a random access was performed for a target PSCell and the UE was configured with CPC, the UE then releases all the conditional reconfigurations that it has stored.Conditional PSCell Addition (CPA) and inter-SN CPCIn 3GPP rel-17 solutions for CPA and inter-SN CPC are being discussed and introduced. The CPA procedure is used for adding a PSCell and / or SCG to the configuration for a UE that is currently only configured with a Master Cell Group (MCG), when associated execution conditions are fulfilled. CPA is initiated by the MN by requesting an SCG configuration, which is to be provided as part of a conditional reconfiguration to the UE, from a (candidate) target SN (T-SN), and then sending it in a conditional reconfiguration to the UE together with the associated execution conditions.Inter-SN CPC can be initiated either by the MN or by the source SN (S-SN), where the signaling towards the source SN and the (candidate) target SNs, as well as towards the UE, in both cases is handled by the MN.CHO with secondary nodeIn 3GPP rel-17, the possibility to configure CHO with a target configuration containing an SCG was introduced. This is described in 3GPP TS 37.340 v 17.3.0, chapter 10.19, and shown in Figures 1 b-c:10.19.2 MR-DC with 5GCThe Conditional Handover with Secondary Node procedure is used for configuration and execution of CHO with SN. This procedure includes the cases where the SN is kept, changed or added. If the SN is kept, the UE context at the SN is kept. If the SN is changed, the UE context at the source SN is moved to the target SN.CHO with candidate SCGAs mentioned above, in rel-17 the configuration of a target candidate cell, e.g., condRRCReconfig of IE OCTET STRING (CONTAINING RRCReconfiguration, within a CHO configuration, e.g., the IE Conditional Reconfiguration as defined in 3GPP TS 38.331 v 17.3.0, may include an SCG configuration, to be applied by the UE when the executioncondition for CHO is fulfilled. The network configures a specific PSCell for a target candidate cell configuration and the UE applies the configuration for the PSCell, and possibly associated SCG SCell(s), when the CHO condition(s) are fulfilled. In rel-17 there are no execution conditions related to the PSCell.In the rel-18 work item for mobility enhancements, one objective is to configure CHO with candidate SCG wherein the UE receives, in addition to the CHO execution condition(s) related to the MCG e.g., CHO candidate cell an offset better than the PCell, execution condition(s) related to the SCG, in addition to the CHO execution condition(s).The following agreements have been made in RAN2 related to this objective:In RAN2#119:• Observation: Current RAN2 Stage-3 specifications can support CHO including target MCG and target SCG in Rel-17.• CHO configuration referring to or including CPC / CPA configuration (intended to be applicable together) can be supported.• FFS: When triggering CHO, UE perform CPC / CPA configuration to start CPC / CPA evaluation, FFS if CHO evaluation and CPC / CPA evaluation is concurrent or sequential.In RAN2#120:• Execution order: the UE doesn’t execute CPC / CPA unless CHO condition is fulfilled (regardless parallel or sequential evaluation).In RAN2#121:• RAN2 agrees to support the simultaneous evaluation of CHO and CPC in Rel- 18.• The UE should not need to unpack any of the nested conditionalconfiguration containers in order to measure, acc to agreement aboveIn RAN2#121bis:For the CHO+CPC case:• When both CHO and CPC conditions are met, both CHO and CPC cell change is executed.• Baseline: The UE waits until both CHO and CPC conditions are met (always), (furthermore, it is assumed that if needed the network can provide acomplementary CHO-only configuration, to avoid failures in deployments where failure would otherwise be likely to happen).• Alternative: FFS if When CHO condition is met, but CPC condition is not met, CHO execution is triggered (and somehow source SCG can be released). IF allowed in the new configuration the UE may continue evaluation of CPC / CPA conditions.In RAN2#122:• [■ ■ ■]• P9: The execution conditions associated with one CHO container includes both CHO execution condition(s) and CPA / CPC execution condition(s), i.e. triggering conditions on both candidate PCell and candidate PSCell.• P10: If there are multiple candidate PSCells associated with one candidate PCell, the NW can provide multiple CHO configurations for the same candidate PCell, i.e. each one contains one MCG configuration (for the same candidate PCell) and one SCG configuration (for different candidate PSCell).• P12: When the CPA / CPC execution condition is met but no CHO execution condition is met, the UE continues to evaluate both CHO and CPA / CPC execution conditions.• For CHO+CPC we only consider execution when BOTH conditions are met.(When the CHO execution condition is met but no CPC execution condition is met, if there is an available CHO-only or Rel-17 CHO with SCG configuration for which the CHO condition is met, the UE performs the CHO-only or Rel-17 CHO with SCG execution, and THUS the network can handle such situation by providing proper configurations).SUMMARYThe disclosed subject matter describes how a UE selects one of the triggered PCells and the least one of the associated triggered PSCells as the selected cells for conditional reconfiguration execution.Some embodiments provide a method for operating a user equipment, UE, for conditional handover, CHO.

A candidate target PCell may also be referred to as target PCell, candidate PCell or CHO candidate cell. One or more candidate PCells may be triggerede.g., candidate PCell which has their CHO execution condition fulfilled and / or multiple triggered candidate PSCells.For example, the UE may be configured as follows:Candidate PCell A: o Associated Candidate PSCell X1 o Associated Candidate PSCell X2 o Associated Candidate PSCell X3Candidate PCell B: o Associated Candidate PSCell Y1 o Associated Candidate PSCell Y2 o Associated Candidate PSCell Y3Candidate PCell C: o No associated PSCellCandidate PCell D: o Associated PSCellIn this example, there is at least one PCell (C) which does not have any associated candidate PSCell and a candidate PCell (D) with an associated PSCell, but not a candidate PSCell, since there is no CPC execution conditions associated to it.There may be a case in which PCell A and PCell B are triggered candidate PCells, i.e. , multiple triggered candidate PCells fulfilling the CHO execution condition(s), having candidates PSCells X1 and X2 also being triggered candidate PSCells associated with A, and candidates PScells Y1, Y2, Y3 being triggered candidate PSCells associated with B.There may also be a case in which PCell C and / or PCell B are also triggered candidate PCells, or only one triggered candidate PCell, e.g., cell A, and multiple of its associated as triggered candidate PSCells, e.g., candidate PSCell X1 and candidate X2.Upon receiving a configuration of one or more candidate target PCells, with at least one of these candidate PCells being associated with one or more candidate PSCells, the UE evaluates the condition of each candidate target PCell, which may be called a CHO execution condition, and the condition of each associated candidate PSCell, which may be called a CPC execution condition. In a first case, when one of the candidate PCells fulfils an associated PCell execution condition, and one of its associated candidate PSCells fulfils the associated PSCell execution condition, the UE executes both CHO and CPC, i.e., the UE need to apply the conditional reconfiguration of the corresponding candidate PCell and the corresponding candidate PSCell, e.g., a single RRCReconfiguration message comprising an MCG configuration and an SCG configuration. However, there are other cases which may happen in which the UE is required to perform a cell selection for the PCell and / or the associated PSCell.Up to Rel-17, when only CHO is configured i.e., no association between a candidate PCell and one or more candidate PSCells, the UE performs CHO execution when a candidate PCell fulfills the CHO execution condition, that possibly having a PSCell associated or not, without a CPC execution condition associated. When multiple candidates fulfill the CHO execution conditions, i.e., when there are multiple triggered candidate PCells, the UE selects one of these triggered candidate PCells, but as there is no CPC condition, the PSCell(s) would not be taken into account.With the introduction in Rel-18 of the scenarios described above, e.g., at least one candidate target PCell associated with one or more candidate PSCells, e.g., with multiple triggered PSCell(s) in particular, it is not obvious how the UE should select a triggered PCell and / or associated triggered PSCell. The existing text in the latest version of the running Change Request (CR) for RRC specifications is shown below (R2-2304928): ******************************************************************************************[...]5.3.5.13.5 Conditional reconfiguration executionThe UE shall:1> if more than one triggered PCell and / or more than one triggered PSCell exists:2> select one of the triggered PCells and / or one of the triggered PSCells as the selected cell(s) for conditional reconfiguration execution;1> else:2> consider the triggered PCell and / or the triggered PSCell as the selected cell(s) for conditional reconfiguration execution;1> for the selected cell(s) of conditional reconfiguration execution:2> apply the stored condRRCReconfig of the selected cell and perform the actions as specified in 5.3.5.3.up to UE implementation which one to select, e.g. the UE considers beams and beam quality to select one of the triggered cells for execution.******************************************************************************************As can be seen above, the criteria for selecting a PCell and / or PSCell is not specified in RRC.According to an embodiment herein, a method performed by a UE e.g., for selecting at least one cell for conditional reconfiguration in a wireless communications network is provided. The method comprises e.g., any one or more out of:The UE 121 receives, from a network node, one or more configurations for conditional reconfiguration. The one or more configurations are related to one or more candidate PCells. At least one of the one or more candidate PCells is associated with one or more candidate PSCells.Upon fulfillment of one or more handover execution conditions, the UE determines one or more triggered candidate PCells and / or one or more triggered candidate PSCells.The UE selects any one or more out of: A PCell from the triggered candidate PCells according to one or more rules of a first type, a PSCell from the triggered candidate PSCells according to one or more rules of a second type, and a PCell from the triggered candidate PCells and a PSCell from the triggered candidate PSCells according to one or more rules of a third typeAccording to another embodiment herein, a UE e.g., configured to select at least one cell for conditional reconfiguration in a wireless communications network. The UE is further configured to e.g., any one or more out of:Receive, from a network node, one or more configurations for conditional reconfiguration. The one or more configurations are adapted to be related to one or more candidate PCells. At least one of the one or more candidate PCells is adapted to be associated with one or more candidate PSCells.Upon fulfillment of one or more handover execution conditions, the determine a plurality of triggered candidate PCells and / or one or more triggered candidate PSCells.Select any one or more out of: A PCell from the triggered candidate PCells according to one or more rules of a first type, a PSCell from the triggered candidate PSCells according to one or more rules of a second type, and a PCell from the triggered candidate PCells and a PSCell from the triggered candidate PSCells according to one or more rules of a third type.Embodiments herein may bring the advantage of an improved mechanism for UE behavior during conditional reconfiguration, such as CHO, SPS. This by, upon fulfillmentof a CHO execution condition, when the UE has CHO at least one candidate PCell that is associated with one or more candidate PSCells, the UE selects and one or more configurations to be applied, e.g., a candidate PCell and a candidate PSCell and respective CHO candidate PCell configuration and a PSCell configuration. The selection is based on different rules that is described in more details below.Figure 2 is a schematic overview depicting a wireless communications network 100, wherein embodiments herein may be implemented. The communications network 100 comprises one or more RANs and one or more CNs. The communications network 100 may use 5G NR but may further use a number of other different technologies, such as, 6G, Wi-Fi, (LTE), LTE-Advanced, Wideband Code Division Multiple Access (WCDMA), Global System for Mobile communications / enhanced Data rate for GSM Evolution (GSM / EDGE), or Ultra Mobile Broadband (UMB), just to mention a few possible implementations.Network nodes, such as a radio network node, operate in the wireless communications network 100. Each of the radio network nodes e.g. provides a number of cells, e.g., PCells and PSCells, and may use these cells for communicating with other network nodes. Each of the radio network nodes may be a transmission and reception point e.g. a network node, a radio access network node such as a base station, a radio base station, a NodeB, an evolved Node B (eNB, eNodeB, eNode B), an NR / g Node B (gNB), a base transceiver station, a radio remote unit, an Access Point Base Station, a base station router, a transmission arrangement of a radio base station, a stand-alone access point, a Wireless Local Area Network (WLAN) access point, an Access Point Station (AP STA), an access controller, a UE acting as an access point or a peer in a Device to Device (D2D) communication, or any other network unit capable of communicating with a UE served by the radio network node depending e.g. on the radio access technology and terminology used.UEs, such as a UE 121, operate in the communications network 100. The UE 121 may e.g. be an NR device, a mobile station, a wireless terminal, an internet of things (loT) device, an enhanced Machine Type Communication (eMTC) device, an NR RedCap device, a CAT-M device, a Vehicle-to-everything (V2X) device, Vehicle-to-Vehicle (V2V) device, a Vehicle-to-Pedestrian (V2P) device, a Vehicle-to-lnfrastructure (V2I) device, a Vehicle-to-Network (V2N) device, a Wi-Fi device, an LTE device, a non-access point (non-AP) STA, a STA, that communicates via a base station, and one or more Access Networks (AN), e.g. RAN, to one or more core networks (CN). It should be understood bythe skilled in the art that the term UE relates to a non-limiting term which means any UE, terminal, wireless communication terminal, user equipment, (D2D) terminal, or node e.g. smart phone, laptop, mobile phone, sensor, relay, mobile tablets or even a small base station communicating within a cell.The wireless communications network 100 further comprises a network node 110. The network node 110 may e.g., be a radio network node 110 or a core network node 110.Methods herein may in one aspect be performed by the UE 121. As an alternative, a Distributed Node (DN) and functionality, e.g. comprised in a cloud 190 as shown in Figure 1, may be used for performing or partly performing the methods of embodiments herein.The cloud 190 may comprise a cloud network infrastructure. A cloud network infrastructure may e.g. be a collection of hardware and software elements such as computing power, networking, storage, and virtualization resources needed to enable cloud computing in a wireless communications network such as e.g. the communications network 100.Examples of embodiment herein, provides methods for a UE conditional reconfiguration procedure, e.g., when one or more candidate PCells and / or candidate PSCells are triggered. This may e.g., be achieved by one or more measures as exemplified below:- The UE 121 receives one or more candidate target PCells for CHO with at least one of the configured candidate PCells being associated with one or more candidate PSCells. This may be received from the network, such as the network node 110.- The UE 121 determines that there is one or more triggered candidate PCells and / or multiple triggered candidate PSCells in response to the fulfillment of CHO and / or CPC / CPA execution conditions, and performs one or more of: i) Selecting a PCell among multiple triggered candidate PCells when there are multiple triggered candidate PCells, according to one or more rules of a first type. ii) Selecting a PSCell among multiple triggered candidate PSCells when there are multiple triggered candidate PSCells, according to one or more rules of a second type. iii) Selecting both a PCell, among multiple triggered candidate PCells and a PSCell among multiple triggered candidate PSCells according to one or more rules of a third type.According to some examples of embodiment herein, the UE 121 may receive from the network, such as the network node 110 one or more of:- At least one candidate target PCells for CHO not being associated with one or more candidate PSCells, and / or- at least one candidate PCells for CHO being associated with a PSCell, but without a CPC execution condition associated to it.According to some examples of embodiment herein, the one or more rules of a first type may be based on one or more of:- One or more measurements, e.g., cell based RSPR, RSRQ, SINR of the triggered PCell(s) and / or the source PCell.- Traffic demands at the UE e.g., for uplink (UL) or for Downlink (DL) and / or the need for establishing Dual Connectivity (DC) at the CHO execution.- Timing and / or order in which execution conditions were fulfilled.- One or more configurations of one or more PSCells associated to one or more of the triggered candidate PCells.- The presence, or absence, of a triggered PSCell associated to at least one of the triggered PCell(s)The presence, or absence, of a PSCell associated to at least one of the triggered candidate PCells.Any other rules for selecting a PCell as exemplified below.According to some examples of embodiment herein, the one or more rules of a second type may be based on one or more of:- One or more measurements, e.g. cell based Reference Received Power (RSRP), Reference Signal Received Quality (RSRQ), Signal to Interference and Noise Ration (SINR) of the triggered candidate PSCells and / or the source PSCell if configured.- Timing and / or order in which execution conditions were fulfilled.- A random access related configuration in at least one of the triggered candidate PSCells e.g., Contention Free Random Access (CFRA), Random Access Channel (RACH) less (RACH-less), 2-steps RACH.- An SCG state associated to the SCG of at least one of the triggered candidate PSCells e.g., deactivated SCG, or activated SCG.- The frequency, e.g., Synchronization Signaling Block (SSB) frequency, of at least one of the triggered candidate PSCells, e.g., in relation to the frequency, e.g., SSB frequency, of the source PSCell if configured.- The subcarrier spacing of at least one of the triggered candidate PSCells, e.g., in relation to the subcarrier spacing of the source PSCell if configured.- Any other rules for selecting a PSCell as exemplified below.According to some examples of embodiment herein, the one or more rules of a third type may be based on one or more of rules for selecting a PCell and a PSCell as exemplified below.According to some examples of embodiment herein, in response to selecting a PCell and / or a PSCell, the UE 121 may access the PCell and / or the PSCell, wherein accessing may comprise one or more of:- The UE 121 initiating a random access procedure with the selected PCell and / or the selected PScell. The random access procedure may comprise transmitting a preamble to a Physical Random Access Channel (PRACH) resource of the selected PSCell and / or a PRACH resource of the selected PCell.- The UE 121 may apply an RRC Reconfiguration associated to the selected PCell and / or the selected PSCell, e.g., an RRC Reconfiguration comprising an MCG configuration in which the selected PCell configuration is included and / or an RRC configuration comprising an SCG configuration in which the selected PSCell configuration is included.- The UE 121 may transmit measurements and scheduling requests to the selected PCell and / or to the selected PSCell, wherein the measurements may comprise RSRP, RSRQ, SINT values.A number of embodiments will now be described, some of which may be seen as alternatives, while some may be used in combination.A method according to embodiments will now be described from the view of the UE121 together with Figure 3. Figure 3 depicts example embodiments of a method performed by the UE121, e.g., for selecting at least one cell for conditional reconfiguration in the wireless communications network 100. The method comprises any one or more of the following actions, which actions may be taken in any suitable order.Action 301The UE 121 receives, from the network node, one or more configurations for conditional reconfiguration. The one or more configurations are related to one or more candidate PCells. At least one of the one or more candidate PCells are associated with one or more candidate PSCells. Each of the one or more candidate PCells may be associated with a CHO execution condition, being an example of a handover execution condition. Each of the one or more candidate PSCells may be associated with a CPC and / or a CPA execution condition, being examples of a handover execution condition. In some embodiments the UE receives a conditional reconfiguration message, where the conditional reconfiguration message configures the UE with a plurality of candidate target PCells and their associated candidate PSCells.Action 302In some embodiments, the UE 121 evaluates the one or more handover execution conditions. This may comprise determining that one or more handover execution conditions are fulfilled.Action 303Upon fulfillment of one or more handover execution conditions, the UE 121 determines one or more triggered candidate PCells and / or one or more triggered candidate PSCells. A triggered candidate PCell and / or triggered candidate PSCell may be associated with a fulfilled handover execution condition. The one or more triggered candidate PSCells may be different PSCells, where each PSCell is associated one or more of the candidate PCells. The one or more triggered PSCells may be the same PSCell, the PSCell is associated one or more of the candidate PCells.In other words, the UE 121 determines one or more triggered candidate PCells and / or a plurality of triggered candidate PSCells, where the plurality of PSCells are the same PSCell associated to one or more of the triggered candidate PCells, or the plurality of PSCells are different PSCells where each of the plurality of PSCells are associated to one or more of the triggered candidate PCells.Action 304The UE 121 selects any one or more out of:- A PCell from the triggered candidate PCells according to one or more rules of a first type,- a PSCell from the triggered candidate PSCells according to one or more rules of a second type, and- a PCell from the triggered candidate PCells and a PSCell from the triggered candidate PSCells according to one or more rules of a third type.Specifically, in response to there being more than one triggered PCell having at least one associated triggered PSCell, selecting one of the triggered PCells and the least one of the associated triggered PSCells as the selected cells for conditional reconfiguration execution, where the selected cells are selected based on one or more rulesExamples of the rules of the first type, the second type and the third type are explained in more details below.Action 305In some embodiments, the UE 121 access the selected PCell and / or PSCell.The accessing may comprise one or more of:- The UE 121 initiating a random access procedure with the selected PCell and / or the selected PScell, e.g., by transmitting a preamble to a PRACH resource of the selected PSCell and a PRACH resource of the selected PCell;- The UE 121 applying an RRC Reconfiguration associated to the selected PCell and the selected PSCell, e.g. an RRC Reconfiguration comprising an MCG configuration in which the selected PCell configuration is included and an SCG configuration in which the selected PSCell configuration is included.The UE 121 transmitting measurements and scheduling requests to the selected PCell and / or to the selected PSCell, wherein measurements comprise RSRP, RSRQ and / or SINR values.Embodiments herein such as the embodiments mentioned above will now be further described and exemplified. The text below is applicable to embodiments herein and may be combined with any suitable embodiment described above.In the disclosure the term “PSCell target candidate cell” should be interpreted in the same manner as terms like PSCell candidate, candidate PSCell, PSCell candidate cell, target PSCell candidate, etc. That refers to a cell which is meant to operate as a PSCell when the UE executes a CHO for a CHO target candidate cell which has an associated PSCell target candidate. The term “SCG candidate” or candidate SCG may also be used for a similar meaning, wherein an SCG contains a PSCell and may contain further Secondary serving cells for the candidate SCG. The terms PSCell candidate and SCG candidate in that sense may be used interchangeably, since a candidate SCG contains a PSCell (and possibly one or more SCell(s) associated to it). A Secondary Cell Group(SCG) corresponds to, for a UE configured with dual connectivity, the subset of serving cells comprising of the PSCell and zero or more secondary cells. A Primary SCG Cell (PSCell), for dual connectivity operation, corresponds to the SCG cell in which the UE performs random access when performing the Reconfiguration with Sync procedure. During the CHO execution together with an associated candidate PSCell, a PSCell is either added (in this case this would be a CPA execution) or changed (in this case we typically called it CPC execution). For that reason, we could generically call that a CPC execution or CPAC execution or CPC / CPA execution. Similarly, the execution conditions associated to the candidate PSCell may be simply called a PSCell execution condition or CPC execution condition, or CPAC execution condition, or CPA / CPA execution condition.In the context of embodiments herein, an associated CPC / CPA execution condition corresponds to at least a condition (configured as one or more measurement identifiers associated to a measurement configuration) which the UE evaluates (e.g. an event A3 / A5 / A4 associated to the one or more measurement identifiers of the measurement configuration) when configured with a CHO target candidate cell with an associated target candidate PSCell.Embodiments herein is applicable at least for the case that a UE is configured with at least one CHO target candidate cell with at least one associated candidate PSCell, and the UE evaluates the fulfillment of CHO execution condition(s) (one or more measld(s) and associated measurement configuration for these measld(s)), and CPC / CPA execution condition(s) (one or more measld(s) and associated measurement configuration for these measld(s)), wherein a PScell target candidate configuration is associated with (e.g. dependent) of the CHO target candidate configuration e.g. SCG configuration inside the RRC Reconfiguration message associated to the PCell target candidate. This “dependency” between a CHO target candidate cell (and its CHO target candidate cell configuration) may be indicated to the UE in different signaling alternatives, so that the PScell target candidate configuration is either within a CPC configuration within the CHO target candidate cell configuration, or as a candidate PSCell configuration configured with the CHO target candidate cell configuration (i.e. in the same IE as the CHO target candidate configuration, but not within the CHO target candidate configuration).A candidate PSCell associated with a candidate PCell comprises a candidate PSCell configuration, or an SCG configuration, associated with a candidate PCell configuration, which may be with or without an associated CPC execution condition. In the case where there is no CPC execution condition associated it may simply be said that a candidate PCell has an associated PSCell, and in the case there is a CPC executioncondition associated it may simply be said that a candidate PCell has an associated candidate PSCell, or in both cases we may refer to a candidate PSCell.As mentioned above, embodiments herein provides methods for the UE 121 to select a PCell, e.g., from one or more triggered candidate PCells, for CHO execution and / or to select a PSCell, e.g., from multiple triggered candidate PSCells, for CPC / CPA execution in the scenario described above when at least one candidate PCell has its CHO execution condition fulfilled. There may be different scenarios which leads the UE 121 to perform the cell selection as provided by the method, which relates to the CHO and / or CPA / CPC execution conditions being fulfilled, such as: a) The CHO and the CPC / CPA conditions are both fulfilled for the at least one candidate PCell associated to a candidate PSCell. b) The CHO conditions are fulfilled, but not the CPC / CPA conditions. c) The CPC / CPA conditions are fulfilled, but not the CHO conditions. d) Multiple candidate PCells for CHO fulfil the conditions for CHO. e) Multiple candidate PSCells for CPC / CPA fulfil the conditions for CPC / CPA.It has been agreed in the options b) and c), the UE 121 waits with any execution, i.e., both the conditions for CHO and CPC / CPA need to be fulfilled before the UE 121 performs any conditional reconfiguration for the case of CHO with associated CPC / CPA. Examples of embodiment herein provides mechanisms for the two last different cases, i.e., options d) and e), where multiple candidate cells for either CHO or CPC / CPA, or both, fulfil the conditions.For the different options, the method may comprise the UE 121 receiving a reconfiguration message, e.g., an RRCReconfiguration message, including a CHO configuration, wherein the CHO configuration comprises at least: i) A CHO candidate PCell configuration, e.g., embedded RRCReconfiguration to be applied upon CHO execution, and ii) a CHO execution condition associated with the CHO candidate PCell configuration.The CHO candidate PCell configuration is associated with a candidate PSCell, or SCG, configuration, also referred to here as a CPC and / or CPA configuration. The CPC / CPA configuration comprises: i) A CPC / CPA candidate PSCell configuration, e.g., candidate SCG configuration, andii) an associated CPC / CPA execution condition, e.g., one or more measlds associated with the CPC / CPA target candidate configuration.The UE 121 may evaluate whether the CHO execution condition is fulfilled and / or evaluating whether the CPA / CPC execution condition is fulfilled.At least one CHO candidate PCell configuration needs to contain an associated candidate PSCell with an associated CPC / CPA execution condition, i.e. , the UE 121 may receive other CHO candidate configurations without any candidate PSCells associated, and consequently without CPC / CPA execution conditions, or, other CHO candidate PCell configurations with a PSCell associated, but without CPC / CPA execution conditions. In that case, the method may comprise the UE selecting a PCell among triggered candidate PCells based on the presence or absence of an associated candidate PSCell or an associated PSCell.According some examples, the UE 121 is configured with one or more candidate PCells, each with a CHO execution condition, and at least one of the candidate PCells has at least one associated candidate PSCell, each with an associated CPC / CPA execution condition. Then, the UE 121 may evaluate the fulfillment of the configured CHO execution conditions and the CPC / CPA execution conditions. There may be different outcomes out of this CHO and CPC condition evaluations and there may be different UE actions depending on the outcome, as shown below.In the context of the embodiments herein, a triggered candidate PCell, or a triggered PCell, is a PCell which fulfills its associated CHO execution condition, and a triggered candidate PSCell, or a triggered PSCell, is a PSCell which fulfills its associated CPC / CPA execution condition.Hence, there may be multiple triggered candidate PCells, leading to the need for the UE 121 to select a PCell according to embodiments herein. The UE 121 may select one of the candidate PCells taking into account the presence of at least one of the triggered candidate PCells being configured with an associated candidate PSCell.One triggered candidate PCell, multiple associated triggered candidate PSCellsAccording to an example of embodiments herein, there may be one triggered candidate PCell with multiple associated triggered candidate PSCells. In such an example, since there is a single triggered candidate PCell, that is the PCell the UE 121 selects. The UE 121 selects one of the triggered candidate PSCells based on one of more rules of a second type.According to this example, in response to evaluating the CHO and / or CPC execution conditions, the UE 121 determines that there is one triggered candidate PCell, e.g., the CHO execution condition for that candidate PCell is fulfilled for one of the CHO configurations, and multiple associated CPA / CPC triggered candidate PSCells, for example, CPC / CPA execution conditions are fulfilled for multiple of the CPC / CPA configurations, i.e., for multiple of the candidate PSCells. In response to that, the UE 121 selects the triggered candidate PCell as the PCell and selects one of the triggered candidate PSCells for the conditional reconfiguration, e.g. CPC or CPA, execution, based on at least one of the following rules or a combination of the following rules, also referred as rules of a second type.In one rule, the UE selects the PSCell with the highest measurement quantity among the multiple triggered candidate PSCells, e.g., the highest RSRP, RSRQ and / or SINR. There may be different manners for the UE 121 to determine the actual measurement quantity that is used for the selection.In one option, the measurement quantity which is used is pre-defined, e.g.,RSRP. For example, when the pre-defined quantity is RSRP, the UE 121 selects the PSCell with the highest RSRP value. The UE would require RSRP measurements for the triggered candidate PSCells associated with the triggered candidate PCell. One sub-option is that the UE selects the PSCell among the triggered candidate PSCell for which measurements on the measurement quantity, e.g., pre-defined, are available. For example, when there are triggered candidate PSCells X1 , X2 and X3, but RSRP values are available only for X1 and X2, the UE selects between X1 and X2 the PSCell with highest RSRP value.In one option, when there are RSRP values available for the triggered candidate PSCells, the UE 121 selects the PSCell with highest RSRP. Otherwise, when RSRP is not available for at least one cell, and RSRQ values are available for all the triggered candidate PSCells, the UE 121 selects the PSCell with highestRSRQ. Otherwise, when RSRQ is not available for at least one cell, and SINR values are available for all the triggered candidate PSCells, the UE 121 selects the PSCell with highest SINR. These situations may occur depending on what has been configured as trigger quantity for the different candidate PSCells.In one option, the measurement quantity the UE 121 uses for selecting the PSCell is the measurement quantity configured as trigger quantity for the CPC / CPA execution condition, for example, the measurement quantityconfigured in the IE MeasTriggerQuantityOffset for CondEvent A3 or CondEvent A5, as defined in 3GPP TS 38.331 v 17.3.0, or the IE MeasTriggerQuantity for CondEvent A4, assuming that the same quantity is used in the CPC / CPA execution conditions for the different triggered candidate PSCells across the multiple Measurement identities associated. One advantage of such approach would be that the UE 121 choses a cell which the UE 121 would rank on top in a measurement report triggered by a measurement event A3, Event A3, as defined in 3GPP TS 38.331 v 17.3.0).In one option, when one type of measurement quantity values are comparable within a range, while another type of measurement quantity values are beyond another range, the better measurement quantity beyond the range is selected by the UE 121 after ranking the triggered candidate PSCells according to that measurement quantity. For example, the UE 121 have RSRP and RSRQ measurements available for triggered candidate PSCells X1 and X2, as follows:RSRP(X1) just slightly better to RSRP(X2), e.g., within 3dB, but RSRQ(X1) much lower RSRQ(X2), e.g., beyond 10dB. The UE 121 selects PSCell X2 based on the measurement quantity RSRQ.MeasTriggerQuantity : : = CHOICE { rsrp RSRP-Range , rsrq RSRQ-Range , s inr SINR-Range}MeasTriggerQuantityOffset : : = CHOICE { rsrp INTEGER ( -30 . . 30 ) , rsrq INTEGER ( -30 . . 30 ) , s inr INTEGER ( -30 . . 30 )In one option, when the UE 121 is configured with a CPC / CPA execution condition associated with more than one measurement identifier, e.g., CPC / CPA execution condition defined as two instances of the IE MeasID, the measurement quantity the UE uses for selecting the PSCell is the measurement quantity configured as trigger quantity of the first MeasID instance for the CPC / CPA execution condition. For example, when the measurement quantity configured in the IE MeasTriggerQuantityOffset, for A3 or A5, or the IE MeasTriggerQuantity, for A4, for the first MeasID is RSRP, the UE 121 uses RSRP.In one option, the measurement quantity the UE 121 uses for selecting the PSCell is a measurement quantity configured as a trigger quantity for the CHO execution condition which has been fulfilled for the selected PCell. For example, when the measurement quantity configured in the IE MeasTriggerQuantityOffset, for CondEvent A3 or Cond Event A5, for the first and / or the second and / or the n-th measurement identifier of the CHO execution condition is set to RSRP, the UE 121 selects the PSCell among the triggered candidate PSCells with highest RSRP. For example, when the measurement quantity configured in the IE MeasTriggerQuantityOffset, for CondEvent A3 or Cond Event A5, for the first and / or the second and / or the n-th measurement identifier of the CHO execution condition is set to RSRQ, the UE 121 selects the PSCell among the triggered PSCell with highest RSRQ.In one rule, the UE 121 selects the PSCell with the measurement quantity with least fluctuation among the multiple triggered candidate PSCells, e.g., least fluctuated RSRP, least fluctuated RSTQ, or least fluctuated SINR. The different manners for the UE 121 to determine the actual measurement quantity used for the selection are similar as above for the highest measurement quantity selection criteria.In one rule, the UE 121 selects the PSCell based on multiple measurement quantities, e.g., the UE selects the PSCell among the triggered candidate PSCells with the strongest RSRP and strongest RSRQ. Thanks to that, the UE 121 selects a PSCell which is the strongest based on multiple measurement quantities. However, when a first PSCell has the strongest RSRP and a second PSCell has the strongest RSRQ, one of the quantities may take precedent, e.g., the UE selects the PSCell with strongest RSRP.In one rule, the UE 121 selects the PSCell among the triggered candidate PSCell based on the cell selection criterion. For example, the UE 121 selects a PSCell which fulfills the cell seletion criterion S, e.g., according to cell selection parameters of the source PCell or the selected PCell among the triggered candidate PCells. When multiple triggered candidate PSCells fulfill the criterion S, as defined in 3GPP TS 38.304 v 17.3.0, the UE 121 may use one of the other rules disclosed herein. In other words, the criterion S may be a pre-requisite for the PScell to be selectable, in addition to be a triggered cell.In one rule, the UE 121 selects the PSCell among the triggered candidate PSCell based on a cell re-selection criterion. For example, the UE 121 selects a PSCell which the UE 121 would have selected for camping in case the UE 121 would have the option to camp among the triggered candidate PSCells, e.g., by applying a ranking function, asdefined in 3GPP TS 38.304 v 17.3.0 for cell reselection. In one option, the cell re-selection parameters for the PSCell selection are the parameters for the source PCell, or for the selected candidate PCell the UE 121 selects among the triggered candidate PCell.In one rule, the UE 121 selects the PSCell among the triggered candidate PSCell based on an MCG measurement configuration of the selected PCell. The selected PCell has an associated MeasConfig, including one or more reporting configurations, e.g., instances of the ReportConfig NR IE, wherein there may be configurations of an A4 event for triggering the UE 121 to report measurements, e.g., RSRP, RSRQ and / or SINR, of cells which may be configured for Carrier Aggregation and / or Dual connectivity, e.g., as PSCells. In one option the UE 121 selects the PSCell among the triggered candidate PSCells which also fulfill an A4 condition, e.g., RSRP of the PSCell higher than a threshold, configured for an event A4 in the MCG MeasConfig of the selected PCell. When multiple of the triggered PSCell also fulfill the event A4 of the MCG MeasConfig of the selected PCell, one or more of the other rules may be used for selecting a single PSCell. Thus, this rule may be used to pre-select a sub-set of selectable PSCells among the triggered candidate PSCells.In one rule, the UE 121 selects the PSCell among the triggered candidate PSCells based on the timing or order in which the CPC / CPA execution condition has been fulfilled. The UE 121 selects a PCell with multiple associated triggered candidate PSCells, but the order in which the PSCells have been fulfilled may have differ.In one example, the UE 121 may be configured with a candidate PCell A and C, with PCell A associated with candidate PScell X1 and candidate PScell X2. Then, if the CPA / CPC condition for the candidate PSCell X2 is fulfilled at time instance to, and the CPA / CPC condition for the candidate PSCell X1 is fulfilled at time instance tO+T, and the condition for the PCell A is fulfilled later, at tO+T 1 (with T1 >T0), and both PSCell X1 and PCSell X2 remain fulfilled at time tO+T1 , the UE 121 selects the PSCell X2. This since that is the cell which has been fulfilled for longer period and is also the cell which has been fulfilled first among the triggered candidate PSCells of the selected PCell A.In another example, the UE 121 may be configured with a candidate PCell A and C, with A associated with candidate PSCell X1 and candidate PSCell X2. Then, if the CPA / CPC condition for the PSCell X2 is fulfilled at time instance to, and the CPA / CPC condition for the PSCell X1 is fulfilled at time instance tO+T, and the condition for the PCell A is fulfilled later, at tO+T 1 (with T1>T0), and bothX1 and X2 remain fulfilled at time t0+T1, the UE selects the PSCell X1. This since that is the cell which has been fulfilled the latest among the triggered candidate PSCells of the selected PCell A and may be the cell which tends to have the condition fulfilled for longer.In one rule, the UE 121 selects the PSCell among the triggered candidate PSCells based on beam measurement of the triggered candidate PSCells.- A beam measurement in this context may correspond to a measurement on a Reference Signal and / or a synchronization signal which is transmitted in a spatial direction and associated with a cell e.g., encoding a physical cell identity. An example of a beam measurement is an SSB measurement, e.g., SS-RSRP, L1-RSRP, SS-RSRQ, SS-SINR, CSI-RSRP, CSI-RSRQ and / or CSI-SINR, as defined in 3GPP TS 38.215 v 17.3.0.In one option, the UE 121 selects the PSCell with the highest number of beams whose measurements are above a threshold.- Assuming SSB measurements, the UE 121 selects the PSCell among the triggered candidate PSCells with the highest number of SS-RSRP, or L1- RSRP, measurements above a threshold. In a sub-option, the threshold may be a threshold configured in the selected PCell configuration, such as: i) the SSB threshold in the random-access configuration of the selected PCell, e.g., rsrp-ThresholdSSB, or ii) the SSB threshold in the random-access configuration of the respective PSCell configuration, or iii) the SSB threshold in a measurement object configuration of the MCG measurement configuration of the selected PCell, for the measurement object associated with the SSB frequency of the corresponding triggered candidate PSCell for number of SSB measurements are being calculated.In one option, the UE 121 selects the PSCell with the beam with the highest beam measurement, according to a measurement quantity, e.g., RSRP, is the highest.For example, if there are two triggered candidate PSCells associated with the selected PCell, and the triggered candidate PSCell X1 has as its highest SSB measurement SS-RSRP(XI) and the triggered candidate PSCell X2 has as its highest SSB measurement SS-RSRP(X2), and SS-RSRP(X2) > SS-RSRP(XI), the UE 121 selects the triggered PSCell X2.In one rule, the UE 121 selects the PSCell among the triggered candidate PSCells based on the presence and / or absence of contention-free random access (CFRA) configurations.In one option, the UE 121 selects the PSCell which has a CFRA, when a single triggered candidate PSCell has a CFRA configuration among the triggered candidate PSCell associated with the selected PCell.In one option, the UE 121 pre-selects the PSCells which have CFRA configurations, and selects the PSCell according to one or the other rules herein, when multiple triggered PSCell have CFRA configurations. In other words, the UE 121 selects PCells only among the ones with CFRA configurations.One benefit here is that the UE would select a PSCell offering better chances to have a faster access and lower interruption time, as CFRA is faster than a contention based random access procedure.In one rule, the UE selects the PSCell among the triggered candidate PSCells based on the presence and / or absence of 2-steps random access (2-step RACH) configurations.In one option, the UE 121 selects the PSCell which has a 2-step RACH configuration, when a single triggered candidate PSCell has a 2-step RACH configuration among the triggered candidate PSCell associated with the selected PCell.In one option, the UE 121 pre-selects the triggered candidate PSCells which have 2-step RACH configurations, and selects a PSCell according to one or the other rules defined herein, when multiple triggered PSCell have 2-step RACH configurations. In other words, the UE 121 selects PSCell only among the ones with 2-step RACH configurations.One benefit here is that the UE 121 would select a PSCell offering better chances to have a faster access and lower interruption time, as 2-step RACH is faster than the 4-steps RACH.In one rule, the UE 121 selects the PSCell among the triggered candidate PSCells based on the presence and / or absence of a RACH-less configuration.In one option, the UE 121 selects the PSCell which has a RACH-less configuration, when a single triggered PSCell has a RACH-less configuration among the triggered candidate PSCells associated with the selected PCell. In one option, the UE 121 pre-selects the triggered candidate PSCells which have RACH-less configurations, and selects the PSCell according to one or the other rules defined herein, when multiple triggered candidate PSCell have RACH-less configurations. In other words, the UE 121 selects PSCells only among the ones with RACH-less configurations.In the case of RACH-less configuration, the UE 121 accesses the selected cell with the transmission of a scheduling request over Physical Uplink Control Channel (PUCCH) and / or a transmission on physical Uplink Shared Channel (PUSCH) based on a pre-configured Uplink grant.One benefit here is that the UE 121 would select a PSCell offering better chances to have a faster access with lower signalling overhead, and lower interruption time, as RACH-less is faster than any other form of random access.In one rule, the UE 121 selects the PSCell among the triggered candidate PSCells based on the SCG state which is configured for the triggered candidate PSCell, e.g,. deactivated SCG, or activated SCG.- The usage of such options for deactivated SCG state may be based on a further criterion, e.g., the UE 121 selects the PSCell with deactivated SCG when the battery is lower than a pre-defined threshold and / or when the traffic demands are low and / or if there is a risk for the UE 121 to become overheated.In one option, the UE 121 selects the triggered PSCell whose SCG state is set to deactivated, when a single triggered PSCell has its SCG state set to deactivated.In one option, the UE 121 pre-selects the PSCells whose SCG is set to deactivated, and further selects the PSCell according to one or the other rules defined herein, when multiple triggered PSCells have the SCG set to deactivated. In other words, the UE 121 selects PCells only among the ones with SCG state set to deactivated.- The usage of such options for activated SCG state may be based on a further criterion, e.g., the UE 121 selects the PSCell with activated SCG when the battery is higher than a pre-defined threshold and / or when the traffic demands are high.In one option, the UE 121 selects the PSCell whose SCG state is set to activated, when a single triggered candidate PSCell has its SCG state set to activated.In one option, the UE 121 pre-selects the PSCells whose SCG is set to activated, and further selects the PSCell according to one or the other rules defined herein, when multiple triggered PSCells have the SCG set to activated. In other words, the UE 121 selects PCells only among the ones with SCG state set to deactivated.In one rule, the UE 121 selects the PSCell among the triggered candidate PSCells with the greatest margin to the execution trigger conditions. Different potential target cells may have different execution trigger conditions.For example, when triggered candidate PSCells X1 and X2 are both triggered cells according to an A4 criterion for RSRP, both have an RSRP above the Cond Event A4 threshold. However, assuming that PSCell X1 is more above the threshold than the PSCell X2, the UE 121 selects PSCell X1.In one rule, the UE 121 selects the PSCell among the triggered candidate PSCells in the same frequency as the frequency of the source PSCell, assuming the UE 121 is in DC when the CHO and CPC / CPA execution conditions are fulfilled.In one example, the UE 121 is in DC with a source PCell with SSB frequency F0 and a PSCell with SSB frequency F1 , so the UE 121 selects the PSCell with the same SSB frequency F1, among the triggered candidate PSCells, assuming they are not in the same SSB frequency F1. When multiple triggered candidate PSCells are in the same frequency as the source PSCell, e.g., SSB frequency F1 , the UE 121 pre-selects the triggered cells in the same frequency as the source PSCell as selectable PSCells and possibly apply one or more of the other rules defined herein to further select the PSCell for the CPC / CPA execution.Being in the same frequency may comprise one or more of:Having the same frequency band.Having the same SSB frequency.Having the same sub-carrier spacing.Having both the same sub-carrier spacing and SSB frequency.Having the same point A reference frequency.Being an intra-frequency neighbour.In one rule, the UE 121 selects the PSCell among the triggered candidate PSCells in a different frequency as the frequency of the source PSCell, assuming the UE 121 is in DC when the CHO and / or CPC / CPA execution conditions are fulfilled.In one option, the selection follows cell reselection priorities set in the system information of the selected PCell.In one rule, the UE 121 selects the PSCell among the triggered candidate PSCells in the same SCG state, e.g. deactivated or activated, as the SCG state of the source PSCell, assuming the UE 121 is in DC when the CHO and / or CPC / CPA execution conditions are fulfilled.In one example, the UE 121 is in DC with a source PCell and a source PSCell with deactivated SCG, so the UE 121 selects the PSCell whose SCG state is set to deactivated, among the triggered candidate PSCells, assuming they are not with deactivated SCG. When multiple triggered candidate PSCells are with deactivated SCG the UE 121 pre-selects the triggered cells in the same SCG state as the source PSCell as selectable PSCells and possibly apply one of the other rules defined herein to further select the PSCell for the CPC / CPA execution.According to some examples of embodiments, in response to evaluating the CHO and CPC / CPA execution conditions, the UE 121 determines that there are multiple triggered candidate PCells, e.g. the CHO execution condition for that candidate PCell is fulfilled for multiple CHO configurations, so the UE 121 first selects a PCell among the triggered candidate PCells and determines that for that selected PCell that there are multiple associated CPA / CPC triggered candidate cells. Thus, in response to that, the UE 121 selects one of the triggered candidate PSCells for the conditional reconfiguration execution, e.g. CPA and / or CPC execution, based on at least one of the rules defined above, such as the second type of rules, or a combination of these following rules.One example of how this may be modelled in the RRC specifications is shown below, wherein the rules defined above represent the UE implementation steps (not specified):5.3.5.13.5 Conditional reconfiguration executionThe UE shall:1> if there is at least one triggered PCell with an associated triggered PSCell (CHO with associated CPC):2> if more than one triggered PCell exists:3> select one of the triggered PCells as the selected cell for conditional reconfiguration execution;2> else:3> consider the triggered PCell as the selected cell for conditional reconfiguration execution;2> if more than one triggered PSCell exists for the selected PCell:3> select one of the triggered PSCells as the selected cell for conditional reconfiguration execution;2> else:3> consider the triggered PSCell as the selected cell for conditional reconfiguration execution;2>for the selected PCell and the selected PSCell, if any, for conditional reconfiguration execution:2> apply the stored condRRCReconfig of the selected PCell and the selected PSCell, if any, and perform the actions as specified in 5.3.5.3; l>else (only CHO or only CPC):2> if more than one triggered cell exists:3> select one of the triggered cells as the selected cell for conditional reconfiguration execution;2> else:3> consider the triggered cell as the selected cell for conditional reconfiguration execution;2> for the selected cell of conditional reconfiguration execution:3> apply the stored condRRCReconfig of the selected cell and perform the actions as specified in 5.3.5.3;NOTE: If multiple NR cells are triggered in conditional reconfiguration execution, it is up to UE implementation which one to select, e.g. the UE considers beams and beam quality to select one of the triggered cells for execution.******************************************************************************************Upon selecting a PCell and an associated PScell the UE 121 may determine the stored RRC configuration, e.g. stored RRCReconfiguration message, associated with the selected PCell and the selected PSCell, and the UE 121 applies the determined stored RRC configuration. Upon applying the configuration, the UE 121 accesses the selected PCell, by performing random access, and possibly perform random access to the selected PSCell.In response to selecting a PCell and / or a PSCell, the accessing may comprise one or more of:- The UE 121 initiating a random access procedure with the selected PCell and / or the selected PScell, e.g., by transmitting a preamble to a PRACH resource of the selected PSCell and a PRACH resource of the selected PCell;The UE 121 applying an RRC Reconfiguration associated to the selected PCell and the selected PSCell, e.g. an RRC Reconfiguration comprising an MCG configuration in which the selected PCell configuration is included and an SCG configuration in which the selected PSCell configuration is included.- The UE 121 transmitting measurements and scheduling requests to the selected PCell and / or to the selected PSCell, wherein measurements comprise RSRP, RSRQ and / or SINR values.Multiple triggered PCells, one triggered PSCellAccording to an example of embodiments herein, there may be multiple triggered candidate PCells with one associated triggered candidate PSCells. In such an example, the UE 121 selects a triggered candidate PCell among multiple triggered candidate PCells, wherein multiple of the triggered candidate PCells have a single associated candidate PSCell which is also a triggered PSCell. There may be different sub-cases, such as: f) The multiple triggered candidate PCells have the same associated triggered PSCell. g) The multiple triggered candidate PCells have different associated triggered PSCell.In the case f), the UE 121 considers the triggered candidate PSCell as the selected PSCell and selects a PCell for CHO execution among the triggered candidate PCells according to the one or more rules of a first type. In the case g) the UE 121 needs to select a PCell and a PSCell, wherein the one or more rules of the first type based onwhich the UE 121 performs the selection of the PCell among the triggered PCells, may take into account the associated triggered PSCells.In one example, to illustrate the sub-case f) in the UE 121 is configured with candidate PCell A and candidate PCell B, as well as candidate PCell C and candidate PCell D, and at least one candidate PSCell X1 which is the same for both. Then, as a result of the evaluation of the CHO and CPC / CPA execution conditions, the candidate PCell A and the candidate PCell B are triggered, while the associated candidate PSCell X1 also triggered, as follows:- Triggered candidate PCell A:- Associated triggered candidate PSCell X1- Associated Candidate PSCell X2- Associated Candidate PSCell X3Candidate A without PSCellCandidate A with PSCell- Triggered candidate PCell B:- Associated triggered candidate PSCell X1- Associated Candidate PSCell Y1- Associated Candidate PSCell Y2- Associated Candidate PSCell Y3Candidate B without PSCellCandidate B with SCGCandidate PCell C:Candidate C without PSCellCandidate A with PSCellCandidate PCell D:- Associated Candidate PSCell Z1- Associated Candidate PSCell Z2Configuration without any candidate PSCell associatedIn one example, to illustrate the sub-case g) the UE 121 is configured with candidate PCell A and candidate PCell B, as well as candidate PCell C and candidate PCell D, and the associated triggered candidate PSCell for A is PSCell X1 , and the associated triggered candidate PSCell for B is PSCell Y1, as follows:Triggered candidate PCell A:- Associated triggered candidate PSCell X1- Associated candidate PSCell X2- Associated candidate PSCell X3Candidate A without PSCellCandidate A with PSCell- Triggered candidate PCell B:- Associated triggered candidate PSCell Y1- Associated candidate PSCell Y2- Associated candidate PSCell Y3Candidate B without PSCellCandidate B with SCGCandidate PCell C:Candidate C without PSCellCandidate A with PSCellCandidate PCell D:- Associated candidate PSCell Z1- Associated candidate PSCell Z2Configuration without any associated candidate PSCellAccording to some examples of embodiments, in response to evaluating the CHO and / or CPC / CPA execution conditions, the UE 121 determines that there are multiple triggered candidate PCells, e.g., the CHO execution condition for these candidate PCells are fulfilled for multiple of the CHO configurations, and, for at least one of the triggered candidate PCells, one associated CPA / CPC triggered candidate PSCells.When that triggered PSCell is the same for the triggered PCells, the UE 121 selects the triggered candidate PSCell as the PSCell for the conditional reconfiguration execution, e.g., CPC / CPA, and selects one of the triggered candidate PCells for the conditional reconfiguration execution, e.g., CHO. When there are different triggered candidate PSCells for the triggered candidate PCells, the UE 121 first selects the PCell for the conditional reconfiguration execution, and, selects as PSCell for CPC / CPA execution the triggered candidate PSCell associated to the selected PCell The selection of a PCell is based on at least one of the following rules or a combination of rules, also referred as rules of a first type:In one rule, the UE 121 selects the PCell with the highest measurement quantity among the multiple triggered candidate PCells, e.g., highest RSRP, highest RSRQ and / orhighest SINR. There may be different manners for the UE 121 to determine the actual measurement quantity that is used for the selection.In one option, the measurement quantity which is used is pre-defined, e.g.,RSRP. For example, when the pre-defined quantity is RSRP, the UE 121 selects the PCell with the highest RSRP value. The UE 121 would require RSRP measurements for the triggered candidate PCells associated with the triggered candidate PSCell. One sub-option is that the UE 121 selects the PCell among the triggered candidate PCell for which measurements on the measurement quantity, e.g., pre-defined, are available. For example, when there are triggered candidate PCells A, B and C but RSRP values are available only for A and B, the UE 121 selects between A and B the PCell with highest RSRP value.In one option, when there are RSRP values available for the triggered candidate PCells, the UE 121 selects the PCell with highest RSRP. Otherwise, when RSRP is not available for at least one cell, and RSRQ values are available for all the triggered candidate PCells, the UE 121 selects the PCell with highestRSRQ. Otherwise, when RSRQ is not available for at least one cell, and SINR values are available for all the triggered candidate PCells, the UE 121 selects the PCell with highest SINR. These situations may occur depending on what has been configured as trigger quantity for the different candidate PCells.In one option, the measurement quantity the UE 121 uses for selecting the PCell is the measurement quantity configured as trigger quantity for the CPC / CPA execution condition, for example, the measurement quantity configured in the IE MeasTriggerQuantityOffset, for CondEvent A3 or CondEvent A5, as defined in 3GPP TS 38.331 v 17.3.0, or the IE MeasTriggerQuantity, for A4, assuming that the same quantity is used in the CPC / CPA execution conditions for the different triggered candidates PCells across the multiple Measurement identities associated. One advantage of such approach would be that the UE 121 choses a cell which the UE 121 would rank on top in a measurement report triggered by a measurement event A3, Event A3, as defined in 3GPP TS 38.331 v 17.3.0.In one option, the measurement quantity is the measurement quantity producing largest difference in values after ranking the triggered candidate PCells according to that measurement quantity. For example, UE 121 have RSRP and RSRQ measurements available for triggered candidate PCells A and A as follows:RSRP(A) just slightly better to RSRP(B), but RSRQ (A) much lower RSRQ (B). The UE 121 selects PCell B, measurement quantity used would be RSRQ in that case.MeasTriggerQuantity : : = CHOICE { rsrp RSRP-Range , rsrq RSRQ-Range , sinr SINR-Range}MeasTriggerQuantityOf f set : : = CHOICE { rsrp INTEGER ( -30 . . 30 ) , rsrq INTEGER ( -30 . . 30 ) , s inr INTEGER ( -30 . . 30 )In one option, when the UE 121 is configured with a CHO execution condition associated with more than one measurement identifier, e.g., CHO execution condition defined as two instances of the IE MeasID, the measurement quantity the UE 121 uses for selecting the PCell is the measurement quantity configured as trigger quantity of the first MeasID instance for the CHO execution condition. For example, when the measurement quantity configured in the IE MeasTriggerQuantityOffset, for A3 or A5, or the IE MeasTriggerQuantity, for A4, for the first MeasID is RSRP, the UE 121 uses RSRP.In one rule, the UE 121 selects the PCell based on multiple measurement quantities, e.g., the UE 121 selects the PCell among the triggered candidate PCells with the strongest RSRP and strongest RSRQ. Thanks to that, the UE 121 selects a PCell which is the strongest based on multiple measurement quantities. However, when a first PCell has the strongest RSRP and a second PCell has the strongest RSRQ, one of the quantities take precedent, e.g., the UE 121 selects the PCell with strongest RSRP.In one rule, the UE 121 selects the PCell among the triggered candidate PCells based on a cell selection criterion. For example, the UE 121 selects a PCell which fulfills the cell selection criterion S, e.g. according to cell selection parameters of the source PCell or the selected PCell among the triggered candidate PCells. When multiple triggered candidate PCells fulfill the criterion S, e.g., as defined in TS 38.304, the UE 121 may use one of the other rules disclosed herein. In other words, the criterion S is a prerequisite for the PCell to be selectable, in addition to be a triggered cell.In one rule, the UE 121 selects the PCell among the triggered candidate PCells based on a cell re-selection criterion. For example, the UE 121 selects a PCell which the UE 121 would have selected for camping in case the UE 121 would have the option to camp among the triggered candidate PCells, by applying a ranking function, as defined in 3GPP TS 38.304 v 17.3.0 for cell reselection. In one option, the cell re-selection parameters for the PCell selection are the parameters for the source PCell, or for the selected PCell the UE 121 selects among the triggered candidate PCells.In one rule, the UE 121 selects the PCell among the triggered candidate PCells based on the timing or order in which the CHO execution condition has been fulfilled. The UE 121 selects a PCell based on the order in which the execution conditions have been fulfilled for the triggered candidate PCells. In one example, the UE 121 selects the triggered PCell for which the CHO execution condition was fulfilled first, and one benefit of that is that the UE 121 can executes CHO and / or CPC / CPA faster, which reduces the possibility of a radio link failure in the source PCell, which improves the overall mobility robustness. In another example the UE 121 selects the triggered PCell for which the CHO execution condition was fulfilled the last, i.e. , the most recent, so the benefit is that the latest cell fulfilling the condition is a potential candidate even if the UE 121 would have move to another cell, so it may be worth selecting that one otherwise a handover would follow from the CHO execution, leading to more signaling.In one rule, the UE 121 selects the PCell among the triggered candidate PCells based on the beam measurements of the triggered candidate PCells.- A beam measurement in this context may correspond to a measurement on a Reference Signal and / or a synchronization signal which is transmitted in a spatial direction and associated with a cell e.g., encoding a physical cell identity. An example of a beam measurement is an SSB measurement, e.g., SS-RSRP, L1-RSRP, SS-RSRQ, SS-SINR, CSI-RSRP, CSI-RSRQ, CSI-SINR, as defined in 3GPP TS 38.215 v 17.3.0.In one option, the UE 121 selects the PCell with the highest number of beams whose measurements are above a threshold.Assuming SSB measurements, the UE 121 selects the PCell among the triggered candidate PCells with the highest number of SS-RSRP, or L1- RSRP, measurements above a threshold.In one option, the UE 121 selects the PCell with the beam with the highest beam measurement, according to a measurement quantity, e.g., RSRP.In one rule, the UE 121 selects the PCell among the triggered candidate PCells based on the presence and / or absence of CFRA configurations.In one option, the UE 121 selects the triggered PCell which has a CFRA configuration, when a single triggered candidate PCells has a CFRA configuration among the triggered candidate PCells.In one option, the UE 121 pre-selects the triggered candidate PCells which have CFRA configurations, and selects the PCell according to one or the other rules herein, when multiple triggered candidate PCells have CFRA configurations. In other words, the UE 121 selects PCells only among the ones with CFRA configurations.One benefit here is that the UE 121 would select a PCell offering better chances to have a faster access and lower interruption time, as CFRA is faster than a contention based random access procedure.In one rule, the UE 121 selects the PCell among the triggered candidate PCells based on the presence and / or absence of 2-step RACH configurations.In one option, the UE 121 selects the PCell which has a 2-step RACH configuration, when a single triggered candidate PCells has a 2-step RACH configuration among the triggered candidate PCells.In one option, the UE 121 pre-selects the triggered candidate PCells which have 2-step RACH configurations, and selects the PCell according to one or the other rules defined in this section, when multiple triggered PCells have 2-step RACH configurations. In other words, the UE 121 selects PCells only among the ones with 2-step RACH configurations.One benefit here is that the UE 121 would select a PCell offering better chances to have a faster access and lower interruption time, as 2-step RACH is faster than the 4-steps RACH.In one rule, the UE 121 selects the PCell among the triggered candidate PCells based on the presence and / or absence of a RACH-less configuration.In one option, the UE 121 selects the triggered PCell which has a RACH-less configuration, when there is a single triggered PCell with a RACH-less configuration among the triggered candidate PCells.In one option, the UE 121 pre-selects the triggered candidate PCells which have RACH-less configurations, and selects the PCell according to one or the other rules defined herein, when multiple triggered candidate PCells have RACH-less configurations. In other words, the UE 121 selects PCells only among the ones with RACH-less configurations.In the case of RACH-less the UE 121 accesses the selected cell with the transmission of a scheduling request over PUCCH and / or a transmission on physical Uplink Shared Channel PUSCH based on a pre-configured Uplink grant.In one option, where there are more than one triggered PCell that has a RACH- less configuration, the UE 121 selects the triggered PCells that has a preconfigured Uplink grant, or a resource for transmission of a scheduling request, that occurs first. In other words, the UE 121 selects the PCell where the UE 121 can perform an uplink transmission first, i.e. with the least delay.One benefit here is that the UE 121 would select a PCell offering better chances to have a faster access with lower signalling overhead, and lower interruption time, as RACH-less is faster than any other form of random access.In one rule, the UE 121 selects the PCell among the triggered candidate PCells based on one or more configurations and / or one or more parameters of a triggered PSCell associated to a triggered PCell.In this case, the UE 121 selects a PCell among triggered candidate PCells based on their candidate PSCell. In some cases, it is better to select a PCell based on what benefits their associated triggered candidate PSCells may provide.In one example, the UE 121 selects the PCell among the triggered candidate PCells where the SCG which is configured for the associated triggered candidate PSCells has the highest number of associated SCG SCells, so that higher data rates can be achieved.In one example, the UE 121 selects the PCell among the triggered candidate PCells where the SCG which is configured for the associated triggered candidate PSCell has the highest number of MIMO layers.In one example, the UE 121 selects the PCell among the triggered candidate PCells where the SCG which is configured for the associated triggered candidate PSCell provides lowest energy consumptionIn one rule, the UE 121 selects the PCell among the triggered candidate PCells based on the SCG state which is configured for the associated triggered candidate PSCell, e.g., deactivated SCG, or activated SCG.The usage of such options for deactivated SCG state may be based on a further criterion, e.g., the UE 121 selects the PCell for which the PSCell has deactivated SCG when the battery is lower than a pre-defined threshold and / or when the traffic demands are low.The usage of such options for activated SCG state may be based on a further criterion, e.g., the UE 121 selects the PCell for which the PSCell has activated SCG when the battery is higher than a pre-defined threshold and / or when the traffic demands are high.In other words, the selection is based on the SCG state that is set in the configuration, for that PCell, for the associated triggered candidate PSCell.In one example, the multiple triggered candidate PCells may each have a single PSCell.In one rule, the UE 121 selects the PCell among the triggered candidate PCells with the greatest margin to the execution trigger conditions. Different potential target cells may have different execution trigger conditions.For example, when triggered candidate PCells A and B are both triggered cells according to an A3 criterion for RSRP, both have an RSRP above the Cond Event A3 threshold. However, assuming that PCell A is more above the threshold than the PCell B, the UE 121 selects PCell A.In one rule, the UE 121 selects the PCell among the triggered candidate PCells in the same frequency as the frequency of the source PCell.Being in the same frequency may comprise one or more of:Having the same frequency band.Having the same SSB frequency.Having the same sub-carrier spacing.Having both the same sub-carrier spacing and SSB frequency.Having the same point A reference frequency.Being an intra-frequency neighbour.In one rule, the UE 121 selects the PCell among the triggered candidate PCells where the triggered candidate PSCell is in the same PSCell frequency as the frequency of the source PSCell.In this case, it may be the case that both triggered candidate PCells have the same frequency as the source PCell, but the UE 121 is in DC with a source PSCell in a frequency F0, while one of the associated triggered candidate PSCells is also in frequency F0, while the other is not. The UE 121 would select the PCell whose associated triggered candidate PSCell has the same frequency as the source PSCell frequency, so an intra-frequency PCell and PSCell change is triggered during the CHO and CPC executions. This case is limited to CHO with CPC, and not applicable for CPA.Notice that being in the same frequency may comprise one or more of:Having the same frequency band.Having the same SSB frequency.Having the same sub-carrier spacing.Having both the same sub-carrier spacing and SSB frequency.Having the same point A reference frequency.Being an intra-frequency neighbour.In one rule, the UE 121 selects the PCell among the triggered candidate PCells in a different frequency as the frequency of the source PCell.In one option, the selection follows cell reselection priorities set in the system information of the selected PCell.In one rule, the UE 121 selects the PCell among the triggered candidate PCells whose triggered PSCell is in a different PSCell frequency as the frequency of the source PSCell.Notice that being in the same frequency may comprise one or more of: Having the same frequency band.Having the same SSB frequency.Having the same sub-carrier spacing.Having both the same sub-carrier spacing and SSB frequency.Having the same point A reference frequency.Being an intra-frequency neighbour.In a special sub-case there are multiple triggered candidate PCells for the UE 121 to perform cell selection of a PCell from, however, each of these multiple triggered candidate PCells have a different associated triggered candidate PSCells, as shown in an example below, similar to sub-case g:Triggered candidate PCell A:- Associated triggered candidate PSCell X1- Associated candidate PSCell X3- Triggered candidate PCell B:- Associated triggered candidate PSCell X2Candidate PCell C:No associated PScellAccording to examples of embodiments herein, in response to evaluating the CHO and CPC / CPA execution conditions, the UE 121 determines that there is a first triggered PSCell associated to a first triggered PCell and a second triggered PSCell associated to a second triggered PSCell wherein the first and second triggered PSCells are different for different triggered PCells. The UE 121 selects one of the triggered PCells based on one or more of the following rules, in addition to the rules above:In one rule, the UE 121 selects the PCell among the triggered candidate PCells for which the associated triggered PSCell is the same as the source PSCell.In this case, the UE 121 is in DC with a source PCell and a source PSCell, and, for some candidate PCells the associated PSCell or associated candidate PSCell is the same as the source PSCell. When the CHO and / or CPC / CPA execution conditions are fulfilled, there are multiple triggered candidate PCells. In that case the UE 121 selects the PCell based on the multiple triggered candidate PSCells, by selecting the PCell whose PScell is the same as the source PSCell, so that the execution of conditional reconfiguration leads to fewer disruptions, as the PSCell would remain the same.In one rule, the UE 121 selects the PCell which has no conditions for associated PSCells and the UE 121 executes CHO only.In one rule, the UE 121 selects the PCell which has an associated PSCell for which the conditions are fulfilled, i.e. CHO with associated CPC / CPA is prioritized over execution of CHO only.In one rule, the UE 121 selects the PCell which has a PSCell, for which the PCell and the PSCell has a certain band combination.In one set of rules, the UE 121 selects the PCell which has a certain PSCell, i.e., based on one or more properties of the associated PSCells, which may be with or without a CPC / CPA execution condition. The certain PSCell may be the PSCell that fulfil any of the rules listed above, e.g.:Selecting the PCell which has the strongest target PSCell considering a radio related measurement, e.g., based on strongest RSRP, RSRQ, SINR and / or highest increase of those.Selecting the PCell with the PSCell based on multiple triggering quantities, the UE 121 selects the PCell with among the triggered PCells with the strongest RSRP and strongest RSRQ.Selecting the PCell with the PSCell based on the cell selection / cell reselection criteria.Selecting the cells based on timing. The cells that first fulfilled the conditions are chosen.Selecting the PCell with the PSCell with highest triggering quantity.Selecting the PCell with the PSCell with the highest number beams above a threshold.Selecting the PCell with the PSCell based on the greatest margin to the execution trigger conditions. Different potential target cells may have different execution trigger conditions.Selecting the PCell with the PSCell based on if there is contention free random access in the cell.In one rule, the UE 121 selects the PCell with a PSCell depending on the presence and / or absence of 2-steps RACH configurations.In one rule, the UE 121 selects the PCell with a PSCell based on the presence and / or absence of a RACH-less configuration.In one rule, the UE 121 selects the PCell with a PSCell in the same frequency as the frequency of the source PSCell.In one rule, the UE 121 selects the PCell with a PSCells in a different frequency as the frequency of the source PSCell.In one rule, the UE 121 selects the PCell with a certain PSCell based on the SCG state which is configured for the triggered PSCell, e.g., deactivated SCG, or activated SCG, same as the current SCG state.In one rule, the UE 121 selects the PCell for which an associated PSCell is the same as the source PSCell, i.e. , as the current serving PSCell before execution of the CHO.- Any of the rules of the second type.Multiple triggered PCells, only a subset of those PCells has an associated PSCell / SCG configurationIn some examples, the UE 121 is configured with multiple candidate PCells for which the execution conditions are fulfilled, i.e., candidate PCells that are triggered, and only a subset of those triggered candidate PCells has a configuration that includes an associated PSCell / SCG configuration. In other words, the configuration for one or more of the triggered candidate PCells includes an associated PSCell / SCG configuration whereas the configuration for one or more of the triggered candidate PCells does not include any associated PSCell / SCG configuration, i.e., it only includes a target MCG configuration.That a triggered candidate PCell has an associated PSCell / SCG configuration may correspond to e.g.:That the CHO configuration for the triggered candidate PCells, to be applied at fulfillment of the associated CHO execution conditions, includes a target MCG configuration for the PCell and a target SCG configuration for the associated PSCell, i.e., there are no execution conditions associated to the associated PSCell.That conditional reconfiguration for the triggered candidate PCell have associated execution conditions for the associated PSCell. The target configuration, which consist of both a target MCG configuration for the PCell and a target SCG configuration for the associated PSCell, is then to be applied when both the execution conditions for the PCell and the execution conditions for the associated PSCell are fulfilled.In one rule, the UE 121 selects the PCell among the triggered candidate PCells for which the configuration includes an associated PSCell / SCG configuration.The selection may thus comprise that the UE 121 selects a triggered candidate PCell for which the configuration includes both an MCG configuration and an SCG configuration, with or without associated execution conditions for the PSCell, instead of a triggered candidate PCell with a configuration that only comprises the MCG configuration for the PCell.In one example, this selection may be based on a further criterion, e.g., that the UE 121 battery level is higher than a pre-defined threhsold and / or when the traffic demands are high and / or that there is no current risk for the UE 121 to become overheated.In one rule, the UE 121 selects the PCell among the triggered PCells for which the configuration does not include any associated PSCell / SCG configuration.The selection may thus consist of that the UE 121 selects a triggered candidate PCell with a configuration that only includes the MCG configuration for the PCell instead of a triggered candidate PCell for which the configuration includes both an MCG configuration and an SCG configuration, with or without associated execution conditions for the PSCell.In one example, this selection may be based on a further criterion, e.g., that the UE 121 battery is lower than a pre-defined threshold and / or when the traffic demands are low and / or if there is a risk for the UE 121 to become overheated.In one rule, the UE 121 selects the PCell among the triggered candidate PCells for which the configuration includes an associated triggered candidate PSCellIn one example, the UE 121 is configured with at least one configuration for a triggered candidate PCell and an associated triggered candidate PSCell and at least one configuration for a triggered candidate PCell and with an associated target SCG, and the UE 121 selects the PCell for which there is also an associated triggered candidate PSCell, i.e., for which there are execution conditions that are fulfilled.In one rule, the UE 121 selects the PCell among the triggered candidate PCells for which the configuration includes a target SCG configuration, without any associated execution conditions for the PSCell.In one example, the UE 121 is configured with at least one configuration for a triggered candidate PCell and an associated triggered candidate PSCell and at least one configuration for a triggered candidate PCell and with an associatedtarget SCG, and the UE 121 selects the PCell for which the configuration has an associated target SCG, i.e., for which no associated execution conditions are configured.Multiple conditional reconfigurations, which fulfil the condition(s), for the same PCell, with difference in associated PSCellIn some examples, the UE 121 is configured with multiple conditional reconfigurations for the same candidate PCell. The different conditional configurations may e.g., comprise one or more conditional configuration that comprises an associated PSCell, i.e., with associated execution conditions for the associated PSCell, one or more conditional configurations comprising a target MCG configuration, for the PCell, and a target SCG configuration, for an associated PSCell, but without any execution conditions for the associated PSCell, and one or more conditional configuration that only comprises a target MCG configuration for the PCell.One or more of the conditional reconfigurations for the UE 121 may have all the associated execution conditions fulfilled at the same time, i.e., the associated execution conditions for the PCell and, if present, for the associated PSCell. Both the PCell and, if configured with execution conditions, the PSCell would then be considered as triggered candidate cells.In one set of rules, the UE 121 is configured with one or more conditional reconfigurations for the same PCell that each include an associated PSCell. where both the PCell and the associated PSCells are triggered candidate cells, and one or more conditional reconfiguration for the same PCell that does not include any associated PSCell, and where the PCell is a triggered candidate cell.In one rule, the UE 121 selects the configuration for the PCell among the configurations that have an associated PSCell, and for which both the PCell and the PSCell are triggered candidate cells.In one example, the selection of a configuration that includes an associated PSCell may be based on a further criterion, e.g., that the UE 121 battery level is higher than a pre-defined threshold and / or when the traffic demands are high and / or that there is no current risk for the UE 121 to become overheated.In one rule, the UE 121 selects the configuration for the PCell among the configurations that do not include any associated PSCell.In one example, the selection of a configuration that does not include any associated PSCell, even when there are other configurations that include anassociated triggered PSCell, may be based on a further criterion, e.g., that the UE 121 battery is lower than a pre-defined threshold and / or when the traffic demands are low and / or if there is a risk for the UE to become overheated.Multiple triggered PCells, multiple triggered PSCellsAccording to an example of embodiments herein, there may be multiple triggered candidate PCells and multiple triggered candidate PSCells. In response to evaluating the CHO and CPC / CPA execution conditions, the UE 121 determines that there are multiple triggered candidate PCells, e.g., the CHO execution condition for these candidate PCells are fulfilled for multiple of the CHO configurations, and multiple associated CPA / CPC triggered candidate PSCells, e.g., CPC / CPA execution conditions are fulfilled for multiple of the CPC / CPA configurations, i.e. for multiple of the target candidate PSCells. In response to that the UE 121 selects the PCell and selects the PSCell for the conditional reconfiguration execution, there are different options:In one option, the UE 121 first selects the PCell and then selects the PSCell or, alternatively, first selects a PSCell and then selects a PCell. The selection of the PCell and the PSCell are done independently of each other. The selection of the PCell may be done according to one or multiple of the rules first type. The selection of the PSCell may be done according to one or multiple of the rules of the second type.In another option, the UE 121 selects the PCell and the PSCell as a joint selection, i.e., the selection of the PCell is impacted by the selection of the PSCell or the selection of the PSCell is impacted by the selection of the PCell.In one rule, the UE 121 selects the PCell among the triggered candidate PCells which has the same PSCell as the source PSCell, assuming the UE 121 is in DC when the CHO and / or CPC execution conditions are fulfilled.In one rule, the UE 121 selects the PCell which has no conditions for associated PSCells, i.e., the UE 121 executes CHO only.In one rule, the UE 121 selects the PCell which has an associated PSCell for which the conditions are fulfilled, i.e., CHO with associated CPC / CPA is prioritized over execution of CHO only.In one rule, the UE 121 selects the PCell which has an associated PSCell, for which the PCell and the PSCell has a certain band combination.In one option the UE 121 selects a PCell which has a certain associated PSCell.The certain PSCell may be the PSCell that fulfil any of the rules listed above, e.g.: Selecting the PCell which has the strongest target PSCell considering a radio related measurement, e.g., based on strongest RSRP, RSRQ, SINR and / or highest increase of those.Selecting the PCell with the PSCell based on multiple triggering quantities, the UE 121 selects the PCell with a PSCells with the strongest RSRP and strongest RSRQ.Selecting the PCell with the PSCell based on the cell selection / cell reselection criteria.Selecting the cells based on timing. The cells that first fulfilled the conditions are chosen.Selecting the PCell with the PSCell with highest triggering quantity.Selecting the PCell with the PSCell with the highest number beams above a threshold.Selecting the PCell with the PSCell based on the greatest margin to the execution trigger conditions. Different potential target cells may have different execution trigger conditions.Selecting the PCell with a certain PSCell based on if there is contention free random access in the PSCell.In one rule, the UE 121 selects the PCell with a certain PSCell depending on the presence and / or absence of 2-step RACH configurations for the PSCell.In one rule, the UE 121 selects the PCell with a certain PSCell based on the presence and / or absence of a RACH-less configuration for the PSCell.In one rule, the UE 121 selects the PCell with a PSCell in the same frequency as the frequency of the source PSCell.In one rule, the UE 121 selects the PCell with a PSCells in a different frequency as the frequency of the source PSCell.In one rule, the UE 121 selects the PCell with a certain PSCell based on the SCG state which is configured for the triggered PSCell, e.g., deactivated SCG or activated SCG, same as the current SCG state.In another option, the selection of the PSCell is impacted by the selection of the PCell, e.g., the UE 121 selects a PSCell which has a certain PCell. The certain PCell may be the PCell that fulfil any of the rules e.g.:Selecting the PSCell which has the strongest target PCell considering a radio related measurement, e.g., based on strongest RSRP, RSRQ, SINR and / or highest increase of those.Selecting the PSCell with the PCell based on multiple triggering quantities, the UE 121 selects the PSCell with a PCell with the strongest RSRP and strongest RSRQ.Selecting the PSCell with the PCell based on the cell selection / cell reselection criteria.Selecting the cells based on timing. The cells that first fulfilled the conditions are chosen.Selecting the PSCell with the PCell with highest triggering quantity.Selecting the PSCell with the PCell with the highest number beams above a threshold.Selecting the PSCell with the PCell based on the greatest margin to the execution trigger conditions. Different potential target cells may have different execution trigger conditions.Selecting the PSCell with the PCell based on if there is contention free random access in the PCell.In one rule, the UE 121 selects the PSCell with a certain PCell depending on the presence and / or absence of 2-steps RACH configurations for the PCell.In one rule, the UE 121 selects the PSCell with a certain PCell based on the presence and / or absence of a RACH-less configuration for the PCell.In one rule, the UE 121 selects the PSCell with a PCell in the same frequency as the frequency of the source PCell.In one rule, the UE 121 selects the PSCell with a PCells in a different frequency as the frequency of the source PCell.Testing of criteria used in the UEThe UE 121 selects one of multiple PSCells based on one or more rules. When the rules are related to measurements, one way to test is to configure the UE 121 to perform periodic measurements reports, e.g., with Measurement Objects associated with the same frequencies as the PSCells associated with the CHO configuration, with a shortperiodicity, while the UE 121 is configured with CHO comprising associated PSCell configurations. Thus, the UE 121 would constantly report the situation of these PSCells, right before the moment the UE 121 needs to select these PSCells. At the same time, the lab set may configure PSCell with different qualities, to observe how the UE 121 is performing the selection.Another possibility is to configure event triggered measurement reports, with triggering conditions so that the report is sent earlier than the fulfillment of the CHO execution condition.Another possibility is to configure the measurement reports in the target configuration, so that the UE 121 reports the PSCell qualities available only after the UE 121 selects the PScell and PCell.One possibility to test the selection criteria used in the UE 121 could be to configure MeasurementReport to be sent for the same event with the same triggering conditions, but with a slightly shorter timeToTrigger. The UE 121 can be moved towards the target PCell and target PSCell to trigger the sending of MeasurementReport and the execution of CHO and CPC / CPA. The MeasurementReport message comprising the measurement results will be received slightly before the execution of the conditional reconfiguration as the timeToTrigger is shorter, but the measurements will show what the UE 121 used as input to the selection of cells as the same events with the same triggering conditions were configured. That means that the measurements in the MeasurementReport message may be used to check what selection criteria the UE 121 used.From a testing point of view to identify the criteria for selecting PCell and / or PSCell as one of the triggered cells the following steps can be considered, by identifying the triggered cell list first, then the selected cell for CHO and CPC / CPA.The current procedure for the conditional reconfiguration evaluation procedure is defined in 3GPP TS 38.331 v 17.3.0 as following.5.3.5.13.4 Conditional reconfiguration evaluationThe UE shall: l>for each condReconfigld within the VarConditionalReconfig'.[...]2>for each measld included in the measIdList within VarMeasConfig indicated in the condExecutionCond or condExecutionCondSCG associated with condReconfigld:[...]3>if the condEventld , associated with condEventA3 , condEventA4 or condEventA5, and if the entry condition(s) applicable for this event associated with the condReconfigld, i.e. the event corresponding with the condEventld(s) of the corresponding con dTriggerConfig within VarConditionalReconfig, is fulfilled for the applicable cells for all measurements after layer 3 filtering taken during the corresponding timeToTrigger defined for this event within the VarConditionalReconfig'.4> consider the event associated with that measld to be fulfilled;[...]2> if event(s) associated with all measldffi) within condTriggerConfig for a target candidate cell within the stored condRRCReconfig are fulfilled:3> consider the target candidate cell within the stored condRRCReconfig, associated with that condReconfigld, as a triggered cell;3>initiate the conditional reconfiguration execution, as specified in 5.3.5.13.5;NOTE 1 : Up to 2 Measld can be configured for each condReconfigld.

For more than one triggered cell exists it’s up to the UE implementation to select one cell for execution.5.3.5.13.5 Conditional reconfiguration executionThe UE shall:l>if more than one triggered cell exists:2> select one of the triggered cells as the selected cell for conditional reconfiguration execution; l>else:2> consider the triggered cell as the selected cell for conditional reconfiguration execution; l>for the selected cell of conditional reconfiguration execution:2> apply the stored condRRCReconfig of the selected cell and perform the actions as specified in 5.3.5.3;NOTE: If multiple NR cells are triggered in conditional reconfiguration execution, it is up to UE implementation which one to select e.g. the UE considers beams and beam quality to select one of the triggered cells for execution.The selected cell for the CHO / CPC / CPA execution may be identified by the UE 121 “accessing” a PCell or PSCell and not “accessing” the other triggered cells.The accessing of the PCell or PSCell includes at least one of the following UE 121 actions:The UE 121 initiating a random access procedure with the PScell, comprising transmitting a preamble to a PRACH resource of the PSCell and / or transmitting a message 3, e.g. for contention resolution;The UE 121 applying an SCG configuration associated with the selected PSCell, e.g., RRCReconfiguration, and transmitting an RRCReconfigurationComplete, e.g., included in an RRCReconfigurationComplete to a network node operation as Master Node.The UE 121 transmitting measurements and scheduling requests to the PSCell, where measurements include reported RSRP, RSRQ, etc.Test scenarios for identifying the selection criterionExample 1 . Selection criteria is based on strongest RSRP for PSCellServing Cell PCell + PSCell on Band 1 and Band 76 in NR.Neighboring cells are multiple PSCells on Band 77 and Band 78 with different power levels but constantly e.g., 5dB in step between Band 77 and Band 78 than Band 76. When Both 77 and Band 78 are the PSCell is within the multiple triggered cells for CHO.Configure the UE 121 to perform periodic measurements reports, e.g., with Measurement Objects associated with the same frequencies as the PSCells associated with the CHO configuration, with a short periodicity, while the UE 121 is configured with CHO including associated PSCell configurations. Thus, the UE 121 would constantly report the situation of these PSCells, right before the moment the UE needs to select these PSCells.- The UE 121 would report RSRP for both PCell and PSCell and 2 neighbor cells before the CHO execution.- Track the PSCell after the CHO execution if it has the strongest RSRP.Another possibility is to configure event triggered measurement reports, with triggering conditions so that the report is sent earlier than the fulfillment of the CHO execution condition.Another possibility is to configure the measurement reports in the target configuration, so that the UE reports these PSCell qualities available only after the UE 121 selects the PScell and PCell.Example 2. Selection criteria is based on the least fluctuated RSRP for PSCell Serving Cell PCell + PSCell on Band 1 and Band 76 in NR.Neighboring cells are multiple PSCells on Band 77 and Band 78 with different power level patterns with fluctuations. Band 76 still has constant power level.- Apply a signal generator or power envelope with a power level pattern with different fluctuations. Band 77 has a power level in STD 10dB higher than Band 76 but fluctuation with 5dB as MSE in time with same pattern in change, e.g., every 5ms. Band 78 has a power level in STD 7dB higher but no fluctuation.When Both 77 and Band 78 are the PSCell is within the multiple triggered cells for CHO.Configure the UE 121 to perform periodic measurements reports, e.g., with Measurement Objects associated with the same frequencies as the PSCells associated with the CHO configuration, with a short periodicity, while the UE 121 is configured with CHO including associated PSCell configurations. Thus, the UE 121 would constantly report the situation of these PSCells, right before the moment the UE 121 needs to select these PSCells.The UE 121 would report RSRP for both PCell and PSCell and 2 neighbor cells before the CHO execution.Track the PSCell after the CHO execution if it has the least fluctuated RSRPExample 3. Selection criteria is based on when the reported RSRP of the triggered PSCells are comparable within a range, e.g., 3dB, while the reported RSRQ of the triggered PSCells are beyond another range, e.g. 10dB, the better RSRQ is selected by the UE for PSCell CHO execution.Serving Cell PCell + PSCell on Band 1 and Band 76 in NR.Neighboring cells are multiple PSCells on Band 77 and Band 78 with different power level patterns. For example, setting 2dB difference constantly between Band 77 and Band 78 where Band 77 is higher than Band 78 and both are higher than Band 76. When Both 77 and Band 78 are the PSCell is within the multiple triggered cells for CHO.- Apply a signal generator or power envelope with a power level pattern with different bandwidth. Band 77 has a lower RSRQ with 11 dB lower than Band 78.When Both 77 and Band 78 are the PSCell is within the multiple triggered cells for CHO.Configure the UE to perform periodic measurements reports, e.g., with Measurement Objects associated with the same frequencies as the PSCells associated with the CHO configuration, with a short periodicity, while the UE is configured with CHO including associated PSCell configurations. Thus, the UE 121 would constantly report the situation of these PSCells, right before the moment the UE 121 needs to select these PSCells.- The UE 121 would report RSRP amd RSRQ for both PCell and PSCell and 2 neighbor cells before the CHO execution.- Track the PSCell after the CHO execution if it’s Band 78 chosen for the CHO execution, as the selection criteria specified.Figure 4 shows an example of arrangement in the UE 121.The UE 121 may comprise an input and output interface 400 configured to communicate with each other.

Embodiments are provided by way of example to convey the scope of the subject matter to those skilled in the art.Figure 5 shows an example of a communication system QQ100 in accordance with some embodiments.In the example, the communication system QQ100 includes a telecommunication network QQ102 that includes an access network QQ104, such as a radio access network (RAN), and a core network QQ106, which includes one or more core network nodes QQ108 (being examples of the network node 110). The access network QQ104 includes one or more access network nodes, such as network nodes QQ110a and QQ110b (one or more of which may be generally referred to as network nodes QQ110 being examples of the network node 110), or any other similar 3rd Generation Partnership Project (3GPP) access nodes or non-3GPP access points. Moreover, as will be appreciated by those of skill in the art, a network node is not necessarily limited to an implementation in which a radio portion and a baseband portion are supplied and integrated by a single vendor. Thus, it will be understood that network nodes include disaggregated implementations or portions thereof. For example, in some embodiments, the telecommunication network QQ102 includes one or more Open-RAN (ORAN) network nodes. An ORAN network node is a node in the telecommunication network QQ102 that supports an ORAN specification (e.g., a specification published by the O-RAN Alliance, or any similar organization) and may operate alone or together with other nodes to implement one or more functionalities of any node in the telecommunication network QQ102, including one or more network nodes QQ110 and / or core network nodes QQ108.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 controlapplication (e.g., xApp) or a non-real time control application (e.g., rApp), or any combination thereof (the adjective “open” designating support of an ORAN specification). The network node may support a specification by, for example, supporting an interface defined by the ORAN specification, such as an A1 , F1 , W1, E1, E2, X2, Xn interface, an open fronthaul user plane interface, or an open fronthaul management plane interface. Moreover, an ORAN access node may be a logical node in a physical node. Furthermore, an ORAN network node may be implemented in a virtualization environment (described further below) in which one or more network functions are virtualized. For example, the virtualization environment may include an O-Cloud computing platform orchestrated by a Service Management and Orchestration Framework via an 0-2 interface defined by the O-RAN Alliance or comparable technologies. The network nodes QQ110 facilitate direct or indirect connection of user equipment (UE), such as by connecting UEs QQ112a, QQ112b, QQ112c, and QQ112d (one or more of which may be generally referred to as UEs QQ112 being examples of the UE 121) to the core network QQ106 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 QQ100 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 QQ100 may include and / or interface with any type of communication, telecommunication, data, cellular, radio network, and / or other similar type of system.The UEs QQ112 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 QQ110 and other communication devices. Similarly, the network nodes QQ110 are arranged, capable, configured, and / or operable to communicate directly or indirectly with the UEs QQ112 and / or with other network nodes or equipment in the telecommunication network QQ102 to enable and / or provide network access, such as wireless network access, and / or to perform other functions, such as administration in the telecommunication network QQ102.In the depicted example, the core network QQ106 connects the network nodes QQ110 to one or more hosts, such as host QQ116. These connections may be direct orindirect via one or more intermediary networks or devices. In other examples, network nodes may be directly coupled to hosts. The core network QQ106 includes one more core network nodes (e.g., core network node QQ108) that are structured with hardware and software components. Features of these components may be substantially similar to those described with respect to the UEs, network nodes, and / or hosts, such that the descriptions thereof are generally applicable to the corresponding components of the core network node QQ108. Example core network nodes include functions of one or more of a Mobile Switching Center (MSC), Mobility Management Entity (MME), Home Subscriber Server (HSS), Access and Mobility Management Function (AMF), Session Management Function (SMF), Authentication Server Function (ALISF), Subscription Identifier Deconcealing function (SIDF), Unified Data Management (UDM), Security Edge Protection Proxy (SEPP), Network Exposure Function (NEF), and / or a User Plane Function (UPF).The host QQ116 may be under the ownership or control of a service provider other than an operator or provider of the access network QQ104 and / or the telecommunication network QQ102, and may be operated by the service provider or on behalf of the service provider. The host QQ116 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.As a whole, the communication system QQ100 of Figure 5 enables connectivity between the UEs, network nodes, and hosts. In that sense, the communication system may be configured to operate according to predefined rules or procedures, such as specific standards that include, but are not limited to: Global System for Mobile Communications (GSM); Universal Mobile Telecommunications System (UMTS); Long Term Evolution (LTE), and / or other suitable 2G, 3G, 4G, 5G standards, or any applicable future generation standard (e.g., 6G); wireless local area network (WLAN) standards, such as the Institute of Electrical and Electronics Engineers (IEEE) 802.11 standards (WiFi); and / or any other appropriate wireless communication standard, such as the Worldwide Interoperability for Microwave Access (WiMax), Bluetooth, Z-Wave, Near Field Communication (NFC) ZigBee, LiFi, and / or any low-power wide-area network (LPWAN) standards such as LoRa and Sigfox.In some examples, the telecommunication network QQ102 is a cellular network that implements 3GPP standardized features. Accordingly, the telecommunications networkQQ102 may support network slicing to provide different logical networks to different devices that are connected to the telecommunication network QQ102. For example, the telecommunications network QQ102 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.In some examples, the UEs QQ112 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 QQ104 on a predetermined schedule, when triggered by an internal or external event, or in response to requests from the access network QQ104. 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).In the example, the hub QQ114 communicates with the access network QQ104 to facilitate indirect communication between one or more UEs (e.g., UE QQ112c and / or QQ112d) and network nodes (e.g., network node QQ110b). In some examples, the hub QQ114 may be a controller, router, content source and analytics, or any of the other communication devices described herein regarding UEs. For example, the hub QQ114 may be a broadband router enabling access to the core network QQ106 for the UEs. As another example, the hub QQ114 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 QQ110, or by executable code, script, process, or other instructions in the hub QQ114. As another example, the hub QQ114 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 QQ114 may be a content source. For example, for a UE that is a VR headset, display, loudspeaker or other media delivery device, the hub QQ114 may retrieve VR assets, video, audio, or other media or data related to sensory information via a network node, which the hub QQ114 then provides to the UE either directly, after performing local processing, and / or after adding additional local content. In still another example, the hub QQ114 acts as a proxy server or orchestrator for the UEs, in particular if one or more of the UEs are low energy loT devices.The hub QQ114 may have a constant / persistent or intermittent connection to the network node QQ110b. The hub QQ114 may also allow for a different communication scheme and / or schedule between the hub QQ114 and UEs (e.g., UE QQ112c and / or QQ112d), and between the hub QQ114 and the core network QQ106. In other examples, the hub QQ114 is connected to the core network QQ106 and / or one or more UEs via a wired connection. Moreover, the hub QQ114 may be configured to connect to an M2M service provider over the access network QQ104 and / or to another UE over a direct connection. In some scenarios, UEs may establish a wireless connection with the network nodes QQ110 while still connected via the hub QQ114 via a wired or wireless connection. In some embodiments, the hub QQ114 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 QQ110b. In other embodiments, the hub QQ114 may be a non-dedicated hub - that is, a device which is capable of operating to route communications between the UEs and network node QQ110b, but which is additionally capable of operating as a communication start and / or end point for certain data channels.Figure 6 shows a UE QQ200 in accordance with some embodiments. As used herein, a UE refers to a device capable, configured, arranged and / or operable to communicate wirelessly with network nodes and / or other UEs. Examples of a UE include, but are not limited to, a smart phone, mobile phone, cell phone, voice over IP (VoIP) phone, wireless local loop phone, desktop computer, personal digital assistant (PDA), wireless cameras, gaming console or device, music storage device, playback appliance, wearable terminal device, wireless endpoint, mobile station, tablet, laptop, laptop- embedded equipment (LEE), laptop-mounted equipment (LME), smart device, wireless customer-premise equipment (CPE), vehicle, vehicle-mounted or vehicle embedded / integrated wireless device, etc. Other examples include any UE identified by the 3rd Generation Partnership Project (3GPP), including a narrow band internet of things (NB-loT) UE, a machine type communication (MTC) UE, and / or an enhanced MTC (eMTC) UE.A UE may support device-to-device (D2D) communication, for example by implementing a 3GPP standard for sidelink communication, Dedicated Short-Range Communication (DSRC), vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), or vehicle-to-everything (V2X). In other examples, a UE may not necessarily have a user in the sense of a human user who owns and / or operates the relevant device. Instead, a UE may represent a device that is intended for sale to, or operation by, a human user butwhich may not, or which may not initially, be associated with a specific human user (e.g., a smart sprinkler controller). Alternatively, a UE may represent a device that is not intended for sale to, or operation by, an end user but which may be associated with or operated for the benefit of a user (e.g., a smart power meter).The UE QQ200 includes processing circuitry QQ202 that is operatively coupled via a bus QQ204 to an input / output interface QQ206, a power source QQ208, a memory QQ210, a communication interface QQ212, and / or any other component, or any combination thereof. Certain UEs may utilize all or a subset of the components shown in Figure QQ2. The level of integration between the components may vary from one UE to another UE. Further, certain UEs may contain multiple instances of a component, such as multiple processors, memories, transceivers, transmitters, receivers, etc.The processing circuitry QQ202 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 QQ210. The processing circuitry QQ202 may be implemented as one or more hardware-implemented state machines (e.g., in discrete logic, field-programmable gate arrays (FPGAs), application specific integrated circuits (ASICs), etc.); programmable logic together with appropriate firmware; one or more stored computer programs, general-purpose processors, such as a microprocessor or digital signal processor (DSP), together with appropriate software; or any combination of the above. For example, the processing circuitry QQ202 may include multiple central processing units (CPUs).In the example, the input / output interface QQ206 may be configured to provide an interface or interfaces to an input device, output device, or one or more input and / or output devices. Examples of an output device include a speaker, a sound card, a video card, a display, a monitor, a printer, an actuator, an emitter, a smartcard, another output device, or any combination thereof. An input device may allow a user to capture information into the UE QQ200. 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. Forexample, a Universal Serial Bus (USB) port may be used to provide an input device and an output device.In some embodiments, the power source QQ208 is structured as a battery or battery pack. Other types of power sources, such as an external power source (e.g., an electricity outlet), photovoltaic device, or power cell, may be used. The power source QQ208 may further include power circuitry for delivering power from the power source QQ208 itself, and / or an external power source, to the various parts of the UE QQ200 via input circuitry or an interface such as an electrical power cable. Delivering power may be, for example, for charging of the power source QQ208. Power circuitry may perform any formatting, converting, or other modification to the power from the power source QQ208 to make the power suitable for the respective components of the UE QQ200 to which power is supplied.The memory QQ210 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 QQ210 includes one or more application programs QQ214, such as an operating system, web browser application, a widget, gadget engine, or other application, and corresponding data QQ216. The memory QQ210 may store, for use by the UE QQ200, any of a variety of various operating systems or combinations of operating systems.The memory QQ210 may be configured to include a number of physical drive units, such as redundant array of independent disks (RAID), flash memory, USB flash drive, external hard disk drive, thumb drive, pen drive, key drive, high-density digital versatile disc (HD-DVD) optical disc drive, internal hard disk drive, Blu-Ray optical disc drive, holographic digital data storage (HDDS) optical disc drive, external mini-dual in-line memory module (DIMM), synchronous dynamic random access memory (SDRAM), external micro-DIMM SDRAM, smartcard memory such as tamper resistant module in the form of a universal integrated circuit card (UICC) including one or more subscriber identity modules (SIMs), such as a USIM and / or ISIM, other memory, or any combination thereof. The UICC may for example be an embedded UICC (eUlCC), integrated UICC (iUICC) or a removable UICC commonly known as ‘SIM card.’ The memory QQ210 may allow the UE QQ200 to access instructions, application programs and the like, stored on transitory or non-transitory memory media, to off-load data, or to upload data. An article ofmanufacture, such as one utilizing a communication system may be tangibly embodied as or in the memory QQ210, which may be or comprise a device-readable storage medium.The processing circuitry QQ202 may be configured to communicate with an access network or other network using the communication interface QQ212. The communication interface QQ212 may comprise one or more communication subsystems and may include or be communicatively coupled to an antenna QQ222. The communication interface QQ212 may include one or more transceivers used to communicate, such as by communicating with one or more remote transceivers of another device capable of wireless communication (e.g., another UE or a network node in an access network). Each transceiver may include a transmitter QQ218 and / or a receiver QQ220 appropriate to provide network communications (e.g., optical, electrical, frequency allocations, and so forth). Moreover, the transmitter QQ218 and receiver QQ220 may be coupled to one or more antennas (e.g., antenna QQ222) and may share circuit components, software or firmware, or alternatively be implemented separately.In the illustrated embodiment, communication functions of the communication interface QQ212 may include cellular communication, Wi-Fi communication, LPWAN communication, data communication, voice communication, multimedia communication, short-range communications such as Bluetooth, near-field communication, location-based communication such as the use of the global positioning system (GPS) to determine a location, another like communication function, or any combination thereof. Communications may be implemented in according to one or more communication protocols and / or standards, such as IEEE 802.11 , Code Division Multiplexing Access (CDMA), Wideband Code Division Multiple Access (WCDMA), GSM, LTE, New Radio (NR), UMTS, WiMax, Ethernet, transmission control protocol / internet protocol (TCP / IP), synchronous optical networking (SONET), Asynchronous Transfer Mode (ATM), QUIC, Hypertext Transfer Protocol (HTTP), and so forth.Regardless of the type of sensor, a UE may provide an output of data captured by its sensors, through its communication interface QQ212, via a wireless connection to a network node. Data captured by sensors of a UE can be communicated through a wireless connection to a network node via another UE. The output may be periodic (e.g., once every 15 minutes if it reports the sensed temperature), random (e.g., to even out the load from reporting from several sensors), in response to a triggering event (e.g., when moisture is detected an alert is sent), in response to a request (e.g., a user initiated request), or a continuous stream (e.g., a live video feed of a patient).As another example, a UE comprises an actuator, a motor, or a switch, related to a communication interface configured to receive wireless input from a network node via a wireless connection. In response to the received wireless input the states of the actuator, the motor, or the switch may change. For example, the UE may comprise a motor that adjusts the control surfaces or rotors of a drone in flight according to the received input or to a robotic arm performing a medical procedure according to the received input.A UE, when in the form of an Internet of Things (loT) device, may be a device for use in one or more application domains, these domains comprising, but not limited to, city wearable technology, extended industrial application and healthcare. Non-limiting examples of such an loT device are a device which is or which is embedded in: a connected refrigerator or freezer, a TV, a connected lighting device, an electricity meter, a robot vacuum cleaner, a voice controlled smart speaker, a home security camera, a motion detector, a thermostat, a smoke detector, a door / window sensor, a flood / moisture sensor, an electrical door lock, a connected doorbell, an air conditioning system like a heat pump, an autonomous vehicle, a surveillance system, a weather monitoring device, a vehicle parking monitoring device, an electric vehicle charging station, a smartwatch, a fitness tracker, a head-mounted display for Augmented Reality (AR) or Virtual Reality (VR), a wearable for tactile augmentation or sensory enhancement, a water sprinkler, an animal- or item-tracking device, a sensor for monitoring a plant or animal, an industrial robot, an Unmanned Aerial Vehicle (UAV), and any kind of medical device, like a heart rate monitor or a remote controlled surgical robot. A UE in the form of an loT device comprises circuitry and / or software in dependence of the intended application of the loT device in addition to other components as described in relation to the UE QQ200 shown in Figure QQ2.As yet another specific example, in an loT scenario, a UE may represent a machine or other device that performs monitoring and / or measurements, and transmits the results of such monitoring and / or measurements to another UE and / or a network node. The UE may in this case be an M2M device, which may in a 3GPP context be referred to as an MTC device. As one particular example, the UE may implement the 3GPP NB-loT standard. In other scenarios, a UE may represent a vehicle, such as a car, a bus, a truck, a ship and an airplane, or other equipment that is capable of monitoring and / or reporting on its operational status or other functions associated with its operation.In practice, any number of UEs may be used together with respect to a single use case. For example, a first UE might be or be integrated in a drone and provide the drone’s speed information (obtained through a speed sensor) to a second UE that is a remotecontroller operating the drone. When the user makes changes from the remote controller, the first UE may adjust the throttle on the drone (e.g. by controlling an actuator) to increase or decrease the drone’s speed. The first and / or the second UE can also include more than one of the functionalities described above. For example, a UE might comprise the sensor and the actuator, and handle communication of data for both the speed sensor and the actuators.Figure 7 shows a network node QQ300 in accordance with some embodiments. As used herein, network node refers to equipment capable, configured, arranged and / or operable to communicate directly or indirectly with a UE and / or with other network nodes or equipment, in a telecommunication network. Examples of network nodes include, but are not limited to, access points (APs) (e.g., radio access points), base stations (BSs) (e.g., radio base stations, Node Bs, evolved Node Bs (eNBs) and NR NodeBs (gNBs)), O- RAN nodes or components of an O-RAN node (e.g., O-RU, O-DU, O-CU).Base stations may be categorized based on the amount of coverage they provide (or, stated differently, their transmit power level) and so, depending on the provided amount of coverage, may be referred to as femto base stations, pico base stations, micro base stations, or macro base stations. A base station may be a relay node or a relay donor node controlling a relay. A network node may also include one or more (or all) parts of a distributed radio base station such as centralized digital units, distributed units (e.g., in an O-RAN access node) and / or remote radio units (RRUs), sometimes referred to as Remote Radio Heads (RRHs).

The network node QQ300 may be composed of multiple physically separate components (e.g., aNodeB component and a RNC component, or a BTS component and a BSC component, etc.), which may each have their own respective components. In certain scenarios in which the network node QQ300 comprises multiple separate components (e.g., BTS and BSC components), one or more of the separate components may be shared among several network nodes. For example, a single RNC may control multiple NodeBs. In such a scenario, each unique NodeB and RNC pair, may in some instances be considered a single separate network node. In some embodiments, the network node QQ300 may be configured to support multiple radio access technologies (RATs). In such embodiments, some components may be duplicated (e.g., separate memory QQ304 for different RATs) and some components may be reused (e.g., a same antenna QQ310 may be shared by different RATs). The network node QQ300 may also include multiple sets of the various illustrated components for different wireless technologies integrated into network node QQ300, for example GSM, WCDMA, LTE, NR, WiFi, Zigbee, Z-wave, LoRaWAN, Radio Frequency Identification (RFID) or Bluetooth wireless technologies. These wireless technologies may be integrated into the same or different chip or set of chips and other components within network node QQ300.The processing circuitry QQ302 may comprise a combination of one or more of a microprocessor, controller, microcontroller, central processing unit, digital signal processor, application-specific integrated circuit, field programmable gate array, or any other suitable computing device, resource, or combination of hardware, software and / or encoded logic operable to provide, either alone or in conjunction with other network node QQ300 components, such as the memory QQ304, to provide network node QQ300 functionality.In some embodiments, the processing circuitry QQ302 includes a system on a chip (SOC). In some embodiments, the processing circuitry QQ302 includes one or more of radio frequency (RF) transceiver circuitry QQ312 and baseband processing circuitry QQ314. In some embodiments, the radio frequency (RF) transceiver circuitry QQ312 and the baseband processing circuitry QQ314 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 QQ312 and baseband processing circuitry QQ314 may be on the same chip or set of chips, boards, or units.The memory QQ304 may comprise any form of volatile or non-volatile computer- readable memory including, without limitation, persistent storage, solid-state memory, remotely mounted memory, magnetic media, optical media, random access memory (RAM), read-only memory (ROM), mass storage media (for example, a hard disk),removable storage media (for example, a flash drive, a Compact Disk (CD) or a Digital Video Disk (DVD)), and / or any other volatile or non-volatile, non-transitory device- readable and / or computer-executable memory devices that store information, data, and / or instructions that may be used by the processing circuitry QQ302. The memory QQ304 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 QQ302 and utilized by the network node QQ300. The memory QQ304 may be used to store any calculations made by the processing circuitry QQ302 and / or any data received via the communication interface QQ306. In some embodiments, the processing circuitry QQ302 and memory QQ304 is integrated.The communication interface QQ306 is used in wired or wireless communication of signaling and / or data between a network node, access network, and / or UE. As illustrated, the communication interface QQ306 comprises port(s) / terminal(s) QQ316 to send and receive data, for example to and from a network over a wired connection. The communication interface QQ306 also includes radio front-end circuitry QQ318 that may be coupled to, or in certain embodiments a part of, the antenna QQ310. Radio front-end circuitry QQ318 comprises filters QQ320 and amplifiers QQ322. The radio front-end circuitry QQ318 may be connected to an antenna QQ310 and processing circuitry QQ302. The radio front-end circuitry may be configured to condition signals communicated between antenna QQ310 and processing circuitry QQ302. The radio front-end circuitry QQ318 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 QQ318 may convert the digital data into a radio signal having the appropriate channel and bandwidth parameters using a combination of filters QQ320 and / or amplifiers QQ322. The radio signal may then be transmitted via the antenna QQ310. Similarly, when receiving data, the antenna QQ310 may collect radio signals which are then converted into digital data by the radio front-end circuitry QQ318. The digital data may be passed to the processing circuitry QQ302. In other embodiments, the communication interface may comprise different components and / or different combinations of components.In certain alternative embodiments, the network node QQ300 does not include separate radio front-end circuitry QQ318, instead, the processing circuitry QQ302 includes radio front-end circuitry and is connected to the antenna QQ310. Similarly, in some embodiments, all or some of the RF transceiver circuitry QQ312 is part of the communication interface QQ306. In still other embodiments, the communication interfaceQQ306 includes one or more ports or terminals QQ316, the radio front-end circuitry QQ318, and the RF transceiver circuitry QQ312, as part of a radio unit (not shown), and the communication interface QQ306 communicates with the baseband processing circuitry QQ314, which is part of a digital unit (not shown).The antenna QQ310 may include one or more antennas, or antenna arrays, configured to send and / or receive wireless signals. The antenna QQ310 may be coupled to the radio front-end circuitry QQ318 and may be any type of antenna capable of transmitting and receiving data and / or signals wirelessly. In certain embodiments, the antenna QQ310 is separate from the network node QQ300 and connectable to the network node QQ300 through an interface or port.The antenna QQ310, communication interface QQ306, and / or the processing circuitry QQ302 may be configured to perform any receiving operations and / or certain obtaining operations described herein as being performed by the network node. Any information, data and / or signals may be received from a UE, another network node and / or any other network equipment. Similarly, the antenna QQ310, the communication interface QQ306, and / or the processing circuitry QQ302 may be configured to perform any transmitting operations described herein as being performed by the network node. Any information, data and / or signals may be transmitted to a UE, another network node and / or any other network equipment.The power source QQ308 provides power to the various components of network node QQ300 in a form suitable for the respective components (e.g., at a voltage and current level needed for each respective component). The power source QQ308 may further comprise, or be coupled to, power management circuitry to supply the components of the network node QQ300 with power for performing the functionality described herein. For example, the network node QQ300 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 QQ308. As a further example, the power source QQ308 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.Embodiments of the network node QQ300 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 nodeQQ300 may include user interface equipment to allow input of information into the network node QQ300 and to allow output of information from the network node QQ300. This may allow a user to perform diagnostic, maintenance, repair, and other administrative functions for the network node QQ300.Figure 8 is a block diagram of a host QQ400, which may be an embodiment of the host QQ116 of Figure QQ1, in accordance with various aspects described herein. As used herein, the host QQ400 may be or comprise various combinations hardware and / or software, including a standalone server, a blade server, a cloud-implemented server, a distributed server, a virtual machine, container, or processing resources in a server farm. The host QQ400 may provide one or more services to one or more UEs.The host QQ400 includes processing circuitry QQ402 that is operatively coupled via a bus QQ404 to an input / output interface QQ406, a network interface QQ408, a power source QQ410, and a memory QQ412. Other components may be included in other embodiments. Features of these components may be substantially similar to those described with respect to the devices of previous figures, such as Figures 14 and QQ3, such that the descriptions thereof are generally applicable to the corresponding components of host QQ400.The memory QQ412 may include one or more computer programs including one or more host application programs QQ414 and data QQ416, which may include user data, e.g., data generated by a UE for the host QQ400 or data generated by the host QQ400 for a UE. Embodiments of the host QQ400 may utilize only a subset or all of the components shown. The host application programs QQ414 may be implemented in a container-based architecture and may provide support for video codecs (e.g., Versatile Video Coding (VVC), High Efficiency Video Coding (HEVC), Advanced Video Coding (AVC), MPEG, VP9) and audio codecs (e.g., FLAG, Advanced Audio Coding (AAC), MPEG, G.711), including transcoding for multiple different classes, types, or implementations of UEs (e.g., handsets, desktop computers, wearable display systems, heads-up display systems). The host application programs QQ414 may also provide for user authentication and licensing checks and may periodically report health, routes, and content availability to a central node, such as a device in or on the edge of a core network. Accordingly, the host QQ400 may select and / or indicate a different host for over-the-top services for a UE. The host application programs QQ414 may support various protocols, such as the HTTP Live Streaming (HLS) protocol, Real-Time Messaging Protocol (RTMP), Real-Time Streaming Protocol (RTSP), Dynamic Adaptive Streaming over HTTP (MPEG-DASH), etc.Figure 9 is a block diagram illustrating a virtualization environment QQ500 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 QQ500 hosted by one or more of hardware nodes, such as a hardware computing device that operates as a network node, UE, core network node, or host. Further, in embodiments in which the virtual node does not require radio connectivity (e.g., a core network node or host), then the node may be entirely virtualized. In some embodiments, the virtualization environment QQ500 includes components defined by the O-RAN Alliance, such as an O- Cloud environment orchestrated by a Service Management and Orchestration Framework via an 0-2 interface.Applications QQ502 (which may alternatively be called software instances, virtual appliances, network functions, virtual nodes, virtual network functions, etc.) are run in the virtualization environment Q400 to implement some of the features, functions, and / or benefits of some of the embodiments disclosed herein.Hardware QQ504 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 QQ506 (also referred to as hypervisors or virtual machine monitors (VMMs)), provide VMs QQ508a and QQ508b (one or more of which may be generally referred to as VMs QQ508), and / or perform any of the functions, features and / or benefits described in relation with some embodiments described herein. The virtualization layer QQ506 may present a virtual operating platform that appears like networking hardware to the VMs QQ508.The VMs QQ508 comprise virtual processing, virtual memory, virtual networking or interface and virtual storage, and may be run by a corresponding virtualization layer QQ506. Different embodiments of the instance of a virtual appliance QQ502 may be implemented on one or more of VMs QQ508, and the implementations may be made indifferent ways. Virtualization of the hardware is in some contexts referred to as network function virtualization (NFV). NFV may be used to consolidate many network equipment types onto industry standard high volume server hardware, physical switches, and physical storage, which can be located in data centers, and customer premise equipment.In the context of NFV, a VM QQ508 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 QQ508, and that part of hardware QQ504 that executes that VM, be it hardware dedicated to that VM and / or hardware shared by that VM with others of the VMs, forms separate virtual network elements. Still in the context of NFV, a virtual network function is responsible for handling specific network functions that run in one or more VMs QQ508 on top of the hardware QQ504 and corresponds to the application QQ502.Hardware QQ504 may be implemented in a standalone network node with generic or specific components. Hardware QQ504 may implement some functions via virtualization. Alternatively, hardware QQ504 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 QQ510, which, among others, oversees lifecycle management of applications QQ502. In some embodiments, hardware QQ504 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 QQ512 which may alternatively be used for communication between hardware nodes and radio units.Figure 10 shows a communication diagram of a host QQ602 communicating via a network node QQ604 with a UE QQ606 over a partially wireless connection in accordance with some embodiments. Example implementations, in accordance with various embodiments, of the UE (such as a UE QQ112a of Figure 5 and / or UE QQ200 of Figure QQ2), network node (such as network node QQ110a of Figure 5 and / or network node QQ300 of Figure QQ3), and host (such as host QQ116 of Figure 5 and / or host QQ400 of Figure QQ4) discussed in the preceding paragraphs will now be described with reference to Figure QQ6.Like host QQ400, embodiments of host QQ602 include hardware, such as a communication interface, processing circuitry, and memory. The host QQ602 also includes software, which is stored in or accessible by the host QQ602 and executable by the processing circuitry. The software includes a host application that may be operable to provide a service to a remote user, such as the UE QQ606 connecting via an over-the-top (OTT) connection QQ650 extending between the UE QQ606 and host QQ602. In providing the service to the remote user, a host application may provide user data which is transmitted using the OTT connection QQ650.The network node QQ604 includes hardware enabling it to communicate with the host QQ602 and UE QQ606. The connection QQ660 may be direct or pass through a core network (like core network QQ106 of Figure QQ1) and / or one or more other intermediate networks, such as one or more public, private, or hosted networks. For example, an intermediate network may be a backbone network or the Internet.The UE QQ606 includes hardware and software, which is stored in or accessible by UE QQ606 and executable by the UE’s processing circuitry. The software includes a client application, such as a web browser or operator-specific “app” that may be operable to provide a service to a human or non-human user via UE QQ606 with the support of the host QQ602. In the host QQ602, an executing host application may communicate with the executing client application via the OTT connection QQ650 terminating at the UE QQ606 and host QQ602. In providing the service to the user, the UE's client application may receive request data from the host's host application and provide user data in response to the request data. The OTT connection QQ650 may transfer both the request data and the user data. The UE's client application may interact with the user to generate the user data that it provides to the host application through the OTT connection QQ650.The OTT connection QQ650 may extend via a connection QQ660 between the host QQ602 and the network node QQ604 and via a wireless connection QQ670 between the network node QQ604 and the UE QQ606 to provide the connection between the host QQ602 and the UE QQ606. The connection QQ660 and wireless connection QQ670, over which the OTT connection QQ650 may be provided, have been drawn abstractly to illustrate the communication between the host QQ602 and the UE QQ606 via the network node QQ604, without explicit reference to any intermediary devices and the precise routing of messages via these devices.As an example of transmitting data via the OTT connection QQ650, in step QQ608, the host QQ602 provides user data, which may be performed by executing a host application. In some embodiments, the user data is associated with a particular humanuser interacting with the UE QQ606. In other embodiments, the user data is associated with a UE QQ606 that shares data with the host QQ602 without explicit human interaction. In step QQ610, the host QQ602 initiates a transmission carrying the user data towards the UE QQ606. The host QQ602 may initiate the transmission responsive to a request transmitted by the UE QQ606. The request may be caused by human interaction with the UE QQ606 or by operation of the client application executing on the UE QQ606. The transmission may pass via the network node QQ604, in accordance with the teachings of the embodiments described throughout this disclosure. Accordingly, in step QQ612, the network node QQ604 transmits to the UE QQ606 the user data that was carried in the transmission that the host QQ602 initiated, in accordance with the teachings of the embodiments described throughout this disclosure. In step QQ614, the UE QQ606 receives the user data carried in the transmission, which may be performed by a client application executed on the UE QQ606 associated with the host application executed by the host QQ602.In some examples, the UE QQ606 executes a client application which provides user data to the host QQ602. The user data may be provided in reaction or response to the data received from the host QQ602. Accordingly, in step QQ616, the UE QQ606 may provide user data, which may be performed by executing the client application. In providing the user data, the client application may further consider user input received from the user via an input / output interface of the UE QQ606. Regardless of the specific manner in which the user data was provided, the UE QQ606 initiates, in step QQ618, transmission of the user data towards the host QQ602 via the network node QQ604. In step QQ620, in accordance with the teachings of the embodiments described throughout this disclosure, the network node QQ604 receives user data from the UE QQ606 and initiates transmission of the received user data towards the host QQ602. In step QQ622, the host QQ602 receives the user data carried in the transmission initiated by the UE QQ606.One or more of the various embodiments improve the performance of OTT services provided to the UE QQ606 using the OTT connection QQ650, in which the wireless connection QQ670 forms the last segment.In an example scenario, factory status information may be collected and analyzed by the host QQ602. As another example, the host QQ602 may process audio and video data which may have been retrieved from a UE for use in creating maps. As another example, the host QQ602 may collect and analyze real-time data to assist in controlling vehicle congestion (e.g., controlling traffic lights). As another example, the host QQ602may store surveillance video uploaded by a UE. As another example, the host QQ602 may store or control access to media content such as video, audio, VR or AR which it can broadcast, multicast or unicast to UEs. As other examples, the host QQ602 may be used for energy pricing, remote control of non-time critical electrical load to balance power generation needs, location services, presentation services (such as compiling diagrams etc. from data collected from remote devices), or any other function of collecting, retrieving, storing, analyzing and / or transmitting data.In some examples, a measurement procedure may be provided for the purpose of monitoring data rate, latency and other factors on which the one or more embodiments improve. There may further be an optional network functionality for reconfiguring the OTT connection QQ650 between the host QQ602 and UE QQ606, in response to variations in the measurement results. The measurement procedure and / or the network functionality for reconfiguring the OTT connection may be implemented in software and hardware of the host QQ602 and / or UE QQ606. In some embodiments, sensors (not shown) may be deployed in or in association with other devices through which the OTT connection QQ650 passes; the sensors may participate in the measurement procedure by supplying values of the monitored quantities exemplified above, or supplying values of other physical quantities from which software may compute or estimate the monitored quantities. The reconfiguring of the OTT connection QQ650 may include message format, retransmission settings, preferred routing etc.; the reconfiguring need not directly alter the operation of the network node QQ604. Such procedures and functionalities may be known and practiced in the art. In certain embodiments, measurements may involve proprietary UE signaling that facilitates measurements of throughput, propagation times, latency and the like, by the host QQ602. The measurements may be implemented in that software causes messages to be transmitted, in particular empty or ‘dummy’ messages, using the OTT connection QQ650 while monitoring propagation times, errors, etc.Although the computing devices described herein (e.g., UEs, network nodes, hosts) may include the illustrated combination of hardware components, other embodiments may comprise computing devices with different combinations of components. It is to be understood that these computing devices may comprise any suitable combination of hardware and / or software needed to perform the tasks, features, functions and methods disclosed herein. Determining, calculating, obtaining or similar operations described herein may be performed by processing circuitry, which may process information by, for example, converting the obtained information into other information, comparing the obtained information or converted information to information stored in the network node,and / or performing one or more operations based on the obtained information or converted information, and as a result of said processing making a determination. Moreover, while components are depicted as single boxes located within a larger box, or nested within multiple boxes, in practice, computing devices may comprise multiple different physical components that make up a single illustrated component, and functionality may be partitioned between separate components. For example, a communication interface may be configured to include any of the components described herein, and / or the functionality of the components may be partitioned between the processing circuitry and the communication interface.
