[0020] Turning to FIG. 1 , this figure shows a block diagram of one possible and non-limiting example in which the examples may be practiced. A user equipment (UE) 110, radio access network (RAN) node 170, and network element(s) 190 are illustrated. In the example of FIG. 1, the user equipment (UE) 110 is in wireless communication with a wireless network 100. A UE is a wireless device that can access the wireless network 100. The UE 110 includes one or more processors 120, one or more memories 125, and one or more transceivers 130 interconnected through one or more buses 127. Each of the one or more transceivers 130 includes a receiver, Rx, 132 and a transmitter, Tx, 133. The one or more buses 127 may be address, data, or control buses, and may include any interconnection mechanism, such as a series of lines on a motherboard or integrated circuit, fiber optics or other optical communication equipment, and the like. A “circuit” may include dedicated hardware or hardware in association with software executable thereon. The one or more transceivers 130 are connected to one or more antennas 128. The one or more memories 125 include computer program code 123. The UE 110 includes a module 140, comprising one of or both parts 140-1 and / or 140-2, which may be implemented in a number of ways. The module 140 may be implemented in hardware as module 140-1, such as being implemented as part of the one or more processors 120. The module 140-1 may be implementedalso as an integrated circuit or through other hardware such as a programmable gate array. In another example, the module 140 may be implemented as module 140-2, which is implemented as computer program code 123 and is executed by the one or more processors 120. For instance, the one or more memories 125 and the computer program code 123 may be configured to, with the one or more processors 120, cause the user equipment 110 to perform one or more of the operations as described herein. The UE 110 communicates with RAN node 170 via a wireless link 111.

[0021] The RAN node 170 in this example is a base station that provides access by wireless devices such as the UE 110 to the wireless network 100. The RAN node 170 may be, for example, a base station for 5G, also called New Radio (NR). In 5G, the RAN node 170 may be a NG-RAN node, which is defined as either a gNB or a ng-eNB. A gNB is a node providing NR user plane and control plane protocol terminations towards the UE, and connected via the NG interface to a 5GC (such as, for example, the network element(s) 190). The ng-eNB is a node providing E- UTRA user plane and control plane protocol terminations towards the UE, and connected via the NG interface to the 5GC. The NG-RAN node may include multiple gNBs, which may also include a central unit (CU) (gNB-CU) 196 and distributed unit(s) (DUs) (gNB-DUs), of which DU 195 is shown. Note that the DU may include or be coupled to and control a radio unit (RU). The gNB- CU is a logical node hosting RRC, SDAP and PDCP protocols of the gNB or RRC and PDCP protocols of the en-gNB that controls the operation of one or more gNB-DUs. The gNB-CU terminates the Fl interface connected with the gNB -DU. The Fl interface is illustrated as reference 198, although reference 198 also illustrates a link between remote elements of the RAN node 170 and centralized elements of the RAN node 170, such as between the gNB-CU 196 and the gNB-DU 195. The gNB-DU is a logical node hosting RLC, MAC and PHY layers of the gNB or en-gNB, and its operation is partly controlled by gNB-CU. One gNB-CU supports one or multiple cells. One cell is supported by only one gNB-DU. The gNB-DU terminates the Fl interface 198 connected with the gNB-CU. Note that the DU 195 is considered to include the transceiver 160, e.g., as part of a RU, but some examples of this may have the transceiver 160 as part of a separate RU, e.g., under control of and connected to the DU 195. The RAN node 170 may also be an eNB (evolved NodeB) base station, for LTE (long term evolution), or any other suitable base station, access point, access node, or node.

[0022] The RAN node 170 includes one or more processors 152, one or more memories 155, one or more network interfaces (N / W I / F(s)) 161, and one or more transceivers 160 interconnected through one or more buses 157. Each of the one or more transceivers 160 includes a receiver, Rx, 162 and a transmitter, Tx, 163. The one or more transceivers 160 are connected to one or more antennas 158. The one or more memories 155 include computer program code 153. The CU 196 may include the processor(s) 152, memories 155, and network interfaces 161. Note that the DU 195 may also contain its own memory / memories and processor(s), and / or other hardware, but these are not shown.

[0023] The RAN node 170 includes a module 150, comprising one of or both parts 150-1 and / or 150-2, which may be implemented in a number of ways. The module 150 may be implemented in hardware as module 150-1, such as being implemented as part of the one or more processors 152. The module 150-1 may be implemented also as an integrated circuit or through other hardware such as a programmable gate array. In another example, the module 150 may be implemented as module 150-2, which is implemented as computer program code 153 and is executed by the one or more processors 152. For instance, the one or more memories 155 and the computer program code 153 are configured to, with the one or more processors 152, cause the RAN node 170 to perform one or more of the operations as described herein. Note that the functionality of the module 150 may be distributed, such as being distributed between the DU 195 and the CU 196, or be implemented solely in the DU 195.

[0024] The one or more network interfaces 161 communicate over a network such as via the links 176 and 131. Two or more gNBs 170 may communicate using, e.g., link 176. The link 176 may be wired or wireless or both and may implement, for example, an Xn interface for 5G, an X2 interface for LTE, or other suitable interface for other standards.

[0025] The one or more buses 157 may be address, data, or control buses, and may include any interconnection mechanism, such as a series of lines on a motherboard or integrated circuit, fiber optics or other optical communication equipment, wireless channels, and the like. For example, the one or more transceivers 160 may be implemented as a remote radio head (RRH) 195 for ETE or a distributed unit (DU) 195 for gNB implementation for 5G, with the other elementsof the RAN node 170 possibly being physically in a different location from the RRH / DU, and the one or more buses 157 could be implemented in part as, for example, fiber optic cable or other suitable network connection to connect the other elements (e.g., a central unit (CU), gNB-CU) of the RAN node 170 to the RRH / DU 195. Reference 198 also indicates those suitable network link(s).

[0026] It is noted that description herein indicates that “cells” perform functions, but it should be clear that equipment which forms the cell will perform the functions. The cell makes up part of a base station. That is, there can be multiple cells per base station. For example, there could be three cells for a single carrier frequency and associated bandwidth, each cell covering one-third of a 360 degree area so that the single base station’s coverage area covers an approximate oval or circle. Furthermore, each cell can correspond to a single carrier and a base station may use multiple carriers. So if there are three 120 degree cells per carrier and two carriers, then the base station has a total of 6 cells.

[0027] The wireless network 100 may include a network element or elements 190 that may include core network functionality, and which provides connectivity via a link or links 181 with a further network, such as a telephone network and / or a data communications network (e.g., the Internet). Such core network functionality for 5G may include access and mobility management function(s) (AMF(s)) and / or user plane functions (UPF(s)) and / or session management function(s) (SMF(s)). Such core network functionality for LTE may include MME (Mobility Management Entity) / SGW (Serving Gateway) functionality. These are merely illustrative functions that may be supported by the network element(s) 190, and note that both 5G and LTE functions might be supported. The RAN node 170 is coupled via a link 131 to a network element 190. The link 131 may be implemented as, e.g., an NG interface for 5G, or an SI interface for LTE, or other suitable interface for other standards. The network element 190 includes one or more processors 175, one or more memories 171, and one or more network interfaces (N / W I / F(s)) 180, interconnected through one or more buses 185. The one or more memories 171 include computer program code 173. The one or more memories 171 and the computer program code 173 are configured to, with the one or more processors 175, cause the network element 190 to perform one or more operations.

[0028] The wireless network 100 may implement network virtualization, which is the process of combining hardware and software network resources and network functionality into a single, software -based administrative entity, a virtual network. Network virtualization involves platform virtualization, often combined with resource virtualization. Network virtualization is categorized as either external, combining many networks, or parts of networks, into a virtual unit, or internal, providing network-like functionality to software containers on a single system. For example, a network may be deployed in a tele cloud, with virtualized network functions (VNF) running on, for example, data center servers. For example, network core functions and / or radio access network(s) (e.g. CloudRAN, O-RAN, edge cloud) may be virtualized. Note that the virtualized entities that result from the network virtualization are still implemented, at some level, using hardware such as processors 152 or 175 and memories 155 and 171, and also such virtualized entities create technical effects.

[0029] It may also be noted that operations of example embodiments of the present disclosure may be carried out by a plurality of cooperating devices (e.g. cRAN).

[0030] The computer readable memories 125, 155, and 171 may be of any type suitable to the local technical environment and may be implemented using any suitable data storage technology, such as semiconductor based memory devices, flash memory, magnetic memory devices and systems, optical memory devices and systems, fixed memory and removable memory. The computer readable memories 125, 155, and 171 may be means for performing storage functions. The processors 120, 152, and 175 may be of any type suitable to the local technical environment, and may include one or more of general purpose computers, special purpose computers, microprocessors, digital signal processors (DSPs) and processors based on a multicore processor architecture, as non-limiting examples. The processors 120, 152, and 175 may be means for performing functions, such as controlling the UE 110, RAN node 170, and other functions as described herein.

[0031] In general, the various example embodiments of the user equipment 110 can include, but are not limited to, cellular telephones such as smart phones, tablets, personal digital assistants (PDAs) having wireless communication capabilities, portable computers having wirelesscommunication capabilities, image capture devices such as digital cameras having wireless communication capabilities, gaming devices having wireless communication capabilities, music storage and playback appliances having wireless communication capabilities, Internet appliances permitting wireless Internet access and browsing, tablets with wireless communication capabilities, as well as portable units or terminals that incorporate combinations of such functions.

[0032] Having thus introduced one suitable but non-limiting technical context for the practice of the example embodiments of the present disclosure, example embodiments will now be described with greater specificity.

[0033] Features as described herein may generally relate to beam management (BM). Beam management may relate to beam prediction in the time and / or spatial domain for overhead and latency reduction, beam selection accuracy improvement, etc. Beam management procedures may be supported with one or more transmission and / or reception points (TRP) of a serving cell. Beam management may include triggering beam switch and / or cell switch procedures in response to measurement(s) of current and / or new beams, reference signals, or cells.

[0034] Features as described herein may generally relate to UE initiated or event driven reporting with respect to beam management (BM), which may be referred to as UE-initiated beam management (UEIBM). The UE-initiated TCI-state / beam reporting feature may refer to the case where the UE may be configured with at least one event / condition, and then the UE may start TCI- state beam reporting if this at least one event / condition occurs or is satisfied. Rel-19 MIMO work item description (RP-234007) is as follows: In R19 multiple input multiple output (MIMO) Phase5 enhancements, one of the objectives is the UE event driven reporting (RP-234007):“...Specify enhancement to facilitate UE-initiated / event-driven beam management for reducing overhead and / or latency, assuming the unified TCI while leveraging (as much as possible) legacy CSI measurement and reporting configuration frameworks, targeting FR2 and sTRP with intra- and inter-cell beam managementUL signaling content(s) (and procedure(s) as required) for UE-initiated / event- driven beam reporting facilitating fast beam switchingUL signaling medium / container considering the UE-initiated / event-driven nature of the UL transmission, designed primarily for the purpose of beam reporting...”

[0035] In the present disclosure, the terms “event triggered”, “event driven” and “event based” may be used interchangeably.

[0036] Rel-17 has introduced the “unified” transmission configuration indicator (TCI) framework, where TCI states providing quasi co-location (QCL) assumptions for the reception of downlink (DL) signals and channels can also be used to provide spatial sources for the transmission of UL signals and channels to determine an uplink (UL) transmission (TX) spatial filter. Eurthermore, the unified TCI framework defines the concept of an indicated TCI state. That means that one or multiple (in case of multi-TRP for instance) of the configured TCI states is / are indicated TCI state(s) at a time. The indicated TCI state can be a joint DL and UL TCI state or separate DL and separate UL TCI states.

[0037] A UE may be configured with a plurality of transmission configuration indicator (TCI) states. Of those configured TCI states, a subset may be activated, such that the UE may be prepared to start tracking / monitoring the reference signals associated with the activated TCI states. Of those activated TCI states, one or more TCI states may be indicated. The UE may then be configured to transmit or / and receive a signal or channel using the indicated TCI state(s).

[0038] A UE can be configured with up to 128 TCI states. The gNB configures the UE via RRC signaling with TCI states, where each TCI state may have one or two source reference signals (RS) that provide quasi co-location (QCL) parameters for the target RS, with only one RS providing QCL type D per TCI state. QCL information may also be used for beam indication provided by the gNB to configure the UE with a transmit / receive beam to be used for downlink and uplink.

[0039] A working assumption is that UE-initiated or event-driven beam reporting is performed via mode A or mode B:“...Working AssumptionOn beam report transmission procedure for UE-initiated / event-driven beam reportingFor mode-A, at least support one-bit indication in the first PUCCH channel to request a resource for a second UL channel to carry beam report.In such case, a periodic PUCCH resource (with PUCCH format 0 / 1) is configured by dedicated RRC signaling.For mode-B, at least support one-bit indication in the first PUCCH channel to notify a second UE channel to carry beam report.In such case, a periodic PUCCH resource (with PUCCH format 0 / 1) is configured by dedicated RRC signaling.FFS: Whether / how to support multi-bit indication in the first PUCCH for mode-A and mode-B, e.g., when multi-event(s) are approved.FFS: details on the dedicated RRC signalingAbove applies at least for the single CC case...”

[0040] Mode A may be comprise dynamic scheduling of uplink control information (UCI) by the gNB, while Mode B may be comprise UE in pre-configured resources for the second UE channel. Modes A and B are further described with reference to FIGs. 2 and 3.

[0041] Various events may trigger UEIBM, including but not limited to Event 2, Event 1, and Event 7. In Event-2, the quality of at least one new beam, such as Ll-RSRP, becomes a “threshold value” better than the current beam. Event-2 has been agreed as an event that can trigger a UEIBM report. For example, the network may configure the UE with a certain threshold, for example 3 dB, and when the UE measures a new beam to have a Ll-RSRP which is 3 dB better than the Ll-RSRP of the current beam, then a UEIBM report may be triggered. In Event- 1, the quality of the current beam is worse than a certain threshold. Event- 1 may be used to avoid costly procedures like BFR. In Event-7, the quality of at least one new beam, such as Ll-RSRP, becomesa threshold value better than the RS derived from the activated TCI state with the M-th best quality. Event-7 may be used to update the active TCI state list.

[0042] The content of a report triggered by an event detected by the UE may include reporting of one or more beams (e.g. measurements of the one or more beams), including the beam that triggered the report (e.g. beam for which the measurements met the criteria for triggering a report). For example, the UL signal content of the UEIBM report with Event-2 with Ll-RSRP as quality metric may comprise N beams, where N is greater than or equal to 1, where N may be configured by the network. At least one of the N reported beams satisfies the condition of Event- 2. Additionally, the UE may also report the current beam (e.g. measurements of the current beam).

[0043] An agreement has been made regarding reference signal (RS) measurement of a current beam in order to detect Event 2 for triggering reporting for beam management:“...AgreementRegarding RS measurement for the current beam for Event 2, for Option-2a, support the both schemes as follows.Scheme- 1: RS for current beam is the QCL RS in the indicated TCI stateFFS: Whether / How to handle the case if only one TRS is configured in the indicated TCI state.Scheme-2: the RS for current beam is the SSB which is QCLed with the QCL RS in the indicated TCI state.Enabling one of either Scheme- 1 or Scheme-2 is selected by NW.FFS: The above selection is via an explicit RRC parameter or an implicit manner, e.g., if the RS(s) for new beam are CSI-RS, Scheme- 1 is enabled; otherwise, Scheme-2 is enabled.(Working Assumption) Enabling of either Scheme- 1 or Scheme-2 should ensure the same RS type for RS measurement for current beam and new beam.The above QCL RS is the RS w.r.t. QCL-TypeD, if there are two QCL RSs in the indicated TCI state...”

[0044] For Event-2, the UE monitors the current beam and a certain number of new beams. More specifically, the UE monitors the RS for the current beam that is related to the indicated TCI state. The RS may be the actual RS in the indicated TCI state, or the RS may be the synchronization signal block (SSB) which is QCLed with the actual RS in the indicated TCI state. The RS(s) for the new beam(s) may be explicitly configured by the network via RRC.

[0045] An agreement has been made regarding reference signal measurement of a new beam in order to detect Event 2 for triggering reporting for beam management:“...AgreementRegarding RS measurement for the new beam for Event 2, at least Option-3 a is supportedOption-3a (explicit manner): The RS(s) for new beam(s) are explicitly configuredFFS: Option-3b / 3cOption-3b: The RS(s) for new beam(s) are implicitly derived from QCL RS(s) of activated TCI state(s).Option-3c: The RS(s) for new beam(s) are implicitly derived from QCL RS(s) of TCI state(s) in a configured subset of the legacy RRC-configured TCI state list...”

[0046] An agreement has been made with respect to the layer 1 reference signal received power (Ll-RSRP) report format for UE-initiated or event-driven beam reporting:“...AgreementOn UE-initiated / e vent-driven beam reporting, regarding Ll-RSRP report format Option- 3 depending on Event-2, for a report instance where N > 1 beam(s) are reported, the following is supported.RRC can enable or disable whether current beam is always reportedWhen enabled by RRC, the current beam + N beams from the measurement RSs for new beam(s) are reportedNote: The reported current beam is NOT counted in the N reported beams.When disabled by RRC, N beams are reported...”

[0052] Referring now to FIG. 2, illustrated is an example of UEIBM mode A (e.g. dynamically scheduled resources for UCI transmission). In mode A, the transmission of an event triggered report (230) is preceded by an uplink indication (e.g. via first physical uplink control channel (PUCCH)) (210). The network requests the event triggered report via downlink control information (DCI) (e.g. indication in the DCI) that includes a UL grant for the event triggered report (220). The UE provisions the event triggered report on the provided UL grant associated with the DCI indication (230).

[0053] Referring now to FIG. 3, illustrated is an example of UEIBM mode B (e.g. preconfigured resources for UCI transmission). In mode B, the transmission of an event triggered report (320) is preceded by an uplink indication (310). The event triggered report (320) is provided on the pre -provisioned UL grant (i.e. periodical grant). The indication (310) may be referred as a “first PUCCH” transmission, and it indicates that the UE provides the event triggered report on the associated UL resource / grant.

[0054] Example embodiments of the present disclosure may be applicable in the case of Mode A and / or Mode B operation.

[0055] The timing for secondary cell activation / deactivation is described as follows in 3GPP TS 38.213 at 3.1:“...Timing for secondary cell activation / deactivationWith reference to slots for PUCCH transmissions, when a UE receives in a PDSCH an activation command [11, TS 38.321] for a secondary cell ending in slot n, the UE applies the corresponding actions in [11, TS 38.321] no later than the minimum requirement defined in [10, TS 38.133] and no earlier than slot n+k, except for the following: the actions related to CSI reporting on a serving cell that is active in slot n+k the actions related to the sCellDeactivationTimer associated with the secondary cell [11, TS 38.321] that the UE applies in slot n+k the actions related to CSI reporting on a serving cell which is not active in slot n+k that the UE applies in the earliest slot after n+k in which the serving cell is active.The value of k is m + 3 ^s^frame’^ _|_ p where slot n+m is a slot indicated for PUCCH transmission with HARQ-ACK information for the PDSCH reception as described inclause 9.2.3 and Ng^rame,tlis a number of slots per subframe for the SCS configuration p of the PUCCH transmission as defined in [4, TS 38.211].With reference to slots for PUCCH transmissions, if a UE receives a deactivation command [11, TS 38.321] for a secondary cell ending in slot n, the UE applies the corresponding actions in [11, TS 38.321] no later than the minimum requirement defined in [10, TS 38.133], except for the actions related to CSI reporting on an activated serving cell which the UE applies in slot n+k.If the sCellDeactivationTimer associated with the secondary cell expires in slot n, the UE applies the corresponding actions in [11, TS 38.321] no later than the minimum requirement defined in [10, TS 38.133], except for the actions related to CSI reporting on an activated serving cell which the UE applies in the first slot that is after slot n + 3 ■ N^b rame,flwhere p is the SCS configuration for PDSCH reception on the secondary cell.1> else if an SCell Activation / Deactivation MAC CE or an Enhanced SCell Activation / Deactivation MAC CE is received deactivating the SCell; or1> if the sCellDeactivationTimer associated with the activated SCell expires; or1> if the SCG associated with the activated SCell is deactivated:2> deactivate the SCell according to the timing defined in TS 38.213 [6];2> stop the sCellDeactivationTimer associated with the SCell;2> stop the bwp-InactivityTimer associated with the SCell;2> deactivate any active BWP associated with the SCell;2> clear any configured downlink assignment and any configured uplink grant Type 2 associated with the SCell respectively;2> clear any PUSCH resource for semi-persistent CSI reporting associated with the SCell;2> suspend any configured uplink grant Type 1 associated with the SCell;2> flush all HARQ buffers associated with the SCell;2> cancel, if any, triggered consistent LBT failure for the SCell.1> if PDCCH on the activated SCell indicates an uplink grant or downlink assignment; or1> if PDCCH on the Serving Cell scheduling the activated SCell indicates an uplink grant or a downlink assignment for the activated SCell; or1> if a MAC PDU is transmitted in a configured uplink grant and LBT failure indication is not received from lower layers; or1> if a MAC PDU is received in a configured downlink assignment:2> restart the sCellDeactivationTimer associated with the SCell.1> if the SCell is deactivated:2> not transmit SRS on the SCell;2> not report CSI for the SCell;2> not transmit on UL-SCH on the SCell;2> not transmit on RACH on the SCell;2> not monitor the PDCCH on the SCell;2> not monitor the PDCCH for the SCell;2> not transmit PUCCH on the SCell;2> if the SCell is configured as a scheduled cell in MC-DCI-SetOfCells and with the search space for DCI to schedule multiple cells (as specified in TS 38.213 [6]) of the same searchSpaceld as the serving cell in which MC- DCI-SetOfCells containing the SCell is configured:3> not monitor the PDCCH for scheduling multiple cells (as specified in TS 38.213 [6]) for the set of cells vaMC-DCI-SetOfCells including the SCell...”

[0056] The UE event triggered reporting may be configured to support carrier aggregation operation. Currently, only single component carrier (CC) operation has been agreed or captured in the discussions. In carrier aggregation, the UE may be configured with one or more secondary / serving cells (SCells) in addition to the primary cell (PCell). Both a PCell and an SCell may be considered serving cells.

[0057] The SCell may be a downlink only cell and it may not be used to carry PUCCH signaling. In this case, the UEIBM signaling, via the first PUCCH channel, and the event triggered CSI report may be carried on another serving cell uplink (such as PCell).

[0058] The network may configure the SCell deactivation based on its implementation. The UE may receive the SCell deactivation command at any point during the communication, or the deactivation may be based on the expiry of a sCellDeactivationTimer (at the UE side).

[0059] As noted above, the current actions the UE is configured to perform are as follows in the event a SCell is deactivated: sounding reference signals (SRS) may not be transmitted on the SCell; channel state information (CSI) may not be reported for the SCell; the uplink shared channel (UL-SCH) may not be transmitted on the SCell; the random access channel (RACH) may not betransmitted on the SCell; the physical downlink control channel (PDCCH) may not be monitored on the SCell; the physical downlink control channel (PDCCH) may not be monitored for the SCell; and / or signaling on the physical uplink control channel (PUCCH) may not be transmitted on the SCell.

[0060] In an example embodiment, if the UE receives an SCell deactivation command for at least one secondary cell for which the UE is configured with event triggered reporting, the UE may be configured to, for example, stop evaluation of the criteria for event triggered reporting associated with the deactivated SCell. In other words, the UE may stop, or not continue, or not start, or not perform determining whether the criteria for triggering a reporting event (e.g. event 1 , 2, 7, etc.) has occurred.

[0061] In an example embodiment, if the UE receives an SCell deactivation command for at least one secondary cell for which the UE is configured with event triggered reporting, the UE may be configured to, for example, stop measurement of the RS set associated with event triggered reporting configuration for the SCell. In other words, the UE may stop, or not continue, or not start, performing measurements on one or more RS or beams that were indicated for detecting a reporting event (e.g. event 1, 2, 7, etc.).

[0062] In an example embodiment, if the UE receives an SCell deactivation command for at least one secondary cell for which the UE is configured with event triggered reporting, the UE may be configured to, for example, stop measurement of the RS associated with the indicated transmission configuration indicator (TCI) state for the event triggered reporting configuration for the SCell. In other words, the UE may stop, or not continue, or not start, performing measurements on one or more RS or beams that were indicated for detecting a reporting event (e.g. event 1, 2, 7, etc.).

[0063] In an example embodiment, if the UE receives an SCell deactivation command for at least one secondary cell for which the UE is configured with event triggered reporting, the UE may be configured to, for example, if the first PUCCH transmission has been triggered (is pending) for the deactivated SCell, cancel or not send the PUCCH transmission on the serving cell where it hasbeen triggered (e.g. on the primary cell or another scell such as PUCCH Scell). In an example embodiment, the event which has been triggered for the SCell may be considered / marked not valid, or may be cancelled. In an example embodiment, the UE may cancel the triggering (e.g. the UE may set the PUCCH transmission to a pending state although event has been triggered) or cancel pending (i.e. the PUCCH transmission is pending but not yet transmitted) transmission of the first PUCCH transmission / signal associated with the event triggered reporting for the SCell.

[0064] In an example embodiment, if the UE has transmitted a first PUCCH signal indicating the reporting event for the deactivated SCell, and has not yet received the DCI command requesting event triggered CSI report associated with the first PUCCH signal (e.g. in Mode A), the UE may determine that it is not required to provision an event triggered report associated with the SCell. Additionally or alternatively, the UE may determine that the event triggered reporting is / has been completed (or cancelled) for the reporting procedure for the reporting configuration (e.g. the UE may stop the MAC / PHY procedure for the event triggered reporting).

[0065] In an example embodiment, if the UE has transmitted the first PUCCH signal indicating the reporting event for the deactivated SCell, the UE may cancel or not send any further transmissions of the first PUCCH channel.

[0066] In an example embodiment, if the UE has transmitted a first PUCCH signal indicating the reporting event for the deactivated SCell, and has received the DCI command requesting the CSI report (e.g. in Mode A), the UE may not be required to provide the CSI report on the allocated UL-SCH resource (UL grant).

[0067] In an example embodiment, if the UE has transmitted a first PUCCH signal indicating the reporting event for the deactivated SCell, and has received the DCI command requesting the CSI report (e.g. in Mode A), and the UE is configured to multiplex the CSI report with other UL- SCH transmission, the UE may be configured to provide the CSI report on the allocated UL-SCH resource (UL grant). In other words, the UL report may only be transmitted to the NW if there is scheduled, for another serving cell, another transmission with which the UL report associated with the deactivated SCell may be multiplexed. In this case, the NW may expect the UE to multiplexthe report associated with the deactivated SCell on UL resources. In an example embodiment, the report content may be the latest measurements. Alternatively, the UE may set the RSRP values and / or resource indicators to values determined by the UE (implementation), (e.g. default or predefined values or set to non-valid values for LI reporting).

[0068] In an example embodiment, the deactivation of the SCell may cause the UE to stop the prohibit timer, if configured for associated with the first PUCCH signal.

[0069] In an example embodiment, the deactivation of the SCell may cause the UE to reset the counter associated with the event evaluation(e.g. clear the value of the counter) for determining whether the event triggered reporting is to be triggered associated with the reporting configuration for the SCell. As an example a counter may be used to count event instances (such as Event-2). When the certain number e.g. one or a configured number of events have been counted, the event triggered report may be triggered.

[0070] In an example embodiment, if the first PUCCH signal is associated with multiple event indications, the event indication associated with the reporting configuration for the deactivated SCell may not be included to the first PUCCH signal, but the pending transmission may not cancelled, or the triggering may not be cancelled. In other words, information associated with the deactivated SCell may be excluded from the PUCCH transmission.

[0071] In an example embodiment, if the UE receives the deactivation command (e.g. MAC CE) or determines that a certain SCell is to be deactivated, the UE may determine to not evaluate, or stop evaluating, the event and / or criteria for the event associated with the SCell.

[0072] In an example embodiment, the event triggered reporting configuration may be associated with an SCell or a particular cell based on the association of reference signals if the at least one resource configuration for evaluation of a new RS / beam is associated with an SCell. Additionally or alternatively, the event triggered reporting configuration may be associated with an SCell or a particular cell based on the association of reference signals if the at least one new RS / beam in the resource configuration for evaluation is associated with the SCell.

[0073] In an example embodiment, any of the embodiments may be limited to specific cells, i.e. some example embodiments may be applied to specific cell such as PCell. As an example, if the uplink signaling and event triggered reporting is associated PCell, the UE may perform one or more of the actions described herein.

[0074] In an example embodiment, the first PUCCH signal may refer to a scheduling request ID associated with event triggered reporting (configuration). Additionally or alternatively, the first PUCCH signal may refer to a PUCCH format carrying information associated with event triggered reporting (configuration). In some examples, different PUCCH formats may be associated with or configured as the first PUCCH signal. As an example, some PUCCH formats may carry single bit information, while some other PUCCH formats may carry multiple bits.

[0075] In an example embodiment, any of the above actions may be performed if the deactivation is determined to be valid after slot X of receiving the command. In other words, any actions occurring before the slot X and between the reception of the deactivation command may be performed. As an example, actions occurring (that would occur) after the slot X may not be performed. As an example, if the DCI may schedule event triggered reporting to be performed after X, but the scheduling DCI may be sent before X, in this case the UE may not transmit report. Alternatively, the event may be triggered, but if the first PUCCH transmission is after X, the PUCCH may be cancelled.

[0076] In an example embodiment, if the UE determines that the SCelldeactivation timer is expiring, or the cell is deactivated on the slot n and the first PUCCH signal / transmission is pending for transmission after slot n, the PUCCH transmission may be cancelled.

[0077] In an example embodiment, if the UE determines that the SCelldeactivation timer is expiring, or the cell is deactivated on the slot n and the first PUCCH transmission is pending for transmission after slot n + S_slots (e.g. 3 slots), the PUCCH transmission may be cancelled. The variable "S_slots” may be determined based, for example, on UE configuration, NW signaling, etc.

[0078] In an example embodiment, if the UE determines that the SCelldeactivation timer is expiring, or the cell is deactivated on the slot n and the CSI report is scheduled / pending for transmission after slot n + S_slots (e.g. 3 slots), the CSI report may be cancelled.

[0079] Referring now to FIG. 4, illustrated is a flow chart illustrating UE behavior according to example embodiments of the present disclosure. At 410, the UE may receive a configuration for UE event triggered reporting for at least one Scell. The configuration may comprise at least one PUCCH resource associated with at least one serving cell other than the at least one SCell.

[0080] At 420, the UE may perform event evaluation for event triggered reporting for the at least one SCell. For example, the UE may measure one or more beams or reference signals and determine whether a metric, for example a condition associated with a Ll-RSRP value threshold is met for triggering beam management reporting.

[0081] At 430, the UE may determine that the at least one SCell is deactivated, for example based on a command or a timer.

[0082] At 440, the UE may determine to cancel at least one of CSI reporting, or uplink transmission (e.g. PUCCH transmission), on the at least one serving cell other than the deactivated SCell.

The example method 500 may include: determining to deactivate a secondary cell configured to a user equipment, wherein the user equipment is configured with at least one serving cell and the secondary cell, wherein the user equipment is configured to transmit an event based report, with respect to the secondary cell, to the at least one serving cell; and based on the determining to deactivate the secondary cell, at least one of: cancelling evaluation of criteria for triggering the event based report; cancelling measurement of a set of reference signals associated with triggering the event based report; resetting a counter associated with triggering the event based report; cancelling measurement of one or more reference signals associated with a transmission configuration indicator state associated with the secondary cell; cancelling an event triggering the event based report; cancelling transmission, to the at least one serving cell, of an uplink indication of the eventbased report; stopping a prohibit timer associated with transmission of the uplink indication; or cancelling transmission, to the at least one serving cell, of the event based report, 520.
