Description

TITLEMETHODS FOR MEASUREMENT REPORTING VIA CONFIGURATION UPDATETECHNICAL FIELD[1] Some example embodiments may generally relate to mobile or wireless telecommunication systems, such as 3rdGeneration Partnership Project (3GPP) Long Term Evolution (LTE), 5thgeneration (5G) radio access technology (RAT), new radio (NR) access technology, 6thgeneration (6G), and / or other communications systems. For example, certain example embodiments may relate to systems and / or methods for supporting periodic and semi-persistent (SP) reporting on physical uplink control channel (PUCCH).BACKGROUND[2] In 3GPP, layer 1 (Ll) / layer 2 (L2) triggered mobility (LTM) is a cell switch procedure, wherein the serving cell (e.g, primary cell (PCell) or primary secondary cell (PS Cell)) of a UE may be switched by the network by sending an LTM cell switch command. An LTM switch command may be delivered by medium access control (MAC) signaling using a MAC control element (CE). Thus, changing between cells may currently be performed without using radio resource control (RRC) signaling as a L3 based handover. LTM cell switch decisions may be based on measurements (e.g, LI measurements) that may be performed and reported (e.g, LI measurement report) by the UE. Measurements and reporting may be based on LTM candidate cell configurations provided by the network for one or more LTM candidate cells. LTM candidate cells may include neighboring cells and / or any current serving cells of the UE (e.g, SCells). Improvements in the LTM procedures and techniques are desired.SUMMARY[3] In accordance with some example embodiments, a method may include transmitting, by a network entity, an indication of at least one resource configurationand at least one reporting configuration for reporting measurements configured for LTM.

[0025] It will be readily understood that the components of certain example embodiments, as generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of some example embodiments of systems, methods,apparatuses, and computer program products for supporting periodic and SP reporting on PUCCH is not intended to limit the scope of certain example embodiments, but is instead representative of selected example embodiments.

[0026] Before the cell switch, a network may optionally activate one or more transmission configuration indicator (TCI) states for one or more candidate cells. Once a candidate cell TCI state is activated, the UE may track the timing of the activated TCI states. The UE may also perform early uplink (UL) synchronization before the cell switch (if requested by the network).

[0027] FIG. 1 depicts an example LTM procedure. At step 1, the UE may transmit a MeasurementReport message to the gNB (z.e., base station). The gNB may determine to configure LTM and initiate candidate cells preparation. At step 2, the gNB may transmit an RRCReconfiguration message to the UE, including the LTM candidate cell configurations of at least one candidate cell. At step 3, the UE may store the LTM candidate cell configurations, and transmit an RRCReconfigurationComplete message to the gNB.

[0028] At step 4a, the UE may perform DL synchronization with candidate cells before receiving the cell switch command. At step 4b, the UE may perform early timing advance (TA) acquisition with candidate cells requested by the network before receiving the cell switch command. For example, this may be performed via contention free random access (CFRA) triggered by a physical downlink control channel (PDCCH) order from the source cell. The UE may then transmit a preamble towards the indicated candidate cell. In order to minimize the data interruption of the source cell due to CFRA towards the candidate cells, the UE may not receive a random access response (RAR) for the purpose of TA value acquisition. The TA value of the candidate cell may be indicated in the cell switch command. The UE may not maintain the TA timer for the candidate cell, and may instead rely on network implementation to guarantee the TA validity.

[0029] At step 5, the UE may perform LI measurements on the configured candidate cells, and may transmit lower-layer measurement reports to the gNB. Measurements, such as LI measurements, may be performed according to the configuration in RRCreconfiguration at step 2. At step 6, the gNB may determine to execute cell switch to a target cell, and may transmit a MAC CE triggering cell switch by including the candidate configuration index of the target cell. The UE may switch to the target cell and apply the configuration indicated by candidate configuration index.

[0030] At step 7, if UE does not have valid TA of the target cell, the UE may perform the random access procedure towards the target cell.

[0031] At step 8, the UE may complete the LTM cell switch procedure (e.g, by sending RRCReconfigurationComplete message to target cell). If the UE has performed a RA procedure in step 7, the UE may consider that LTM execution is successfully completed when the random access procedure is successfully completed. For LTM without random access channel (RACH), the UE may consider that LTM execution is successfully completed when the UE determines that the network has successfully received its first UL data. The UE may determine successful reception of its first UL data by receiving a PDCCH addressing the UE’s cell-radio network temporary identifier (C-RNTI) in the target cell, which may schedule a new transmission following the first UL data. It is noted that steps 4-8 may be performed multiple times for subsequent LTM cell switch using the LTM candidate cell configurations provided at step 2.

[0032] In LTM, the UE may perform a MAC reset. Using RRC signalling, the network may control whether the UE performs radio link control (RLC) reestablishment and packet data convergence protocol (PDCP) data recovery during cell switching. The PDCP data recovery procedure may be applied to the RLC acknowledge mode (AM) data radio bearers (DRBs) for inter-distributed unit (DU) LTM cell switch.

[0033] For LTM, information about measurement resources (e.g, synchronization signal block (SSB) or CSI-RS) from LTM candidate cells may be provided to the UE so that the UE can make measurements. The UE may also be configured with LI measurement reporting configuration where the UE can report the measurements. For LTM, periodic and SP report on PUCCH, SP reporting on physical uplink shared channel (PUS CH), and aperiodic report on PUS CH may be supported.

[0034] Each reporting setting (e.g, LTM-CSI-ReportConfig may be associated with a LTM resource configuration for channel measurement, and may contain the parameters for time-domain behavior provided by Itm-ReportConfigType {i.e., periodic, SP report on PUCCH, SP report on PUSCH, aperiodic report on PUSCH), the number of candidate cells and the number of reference signals per candidate cell provided by noOfReportedCells, and noOfReportedRS-PerCell, respectively, including LI measurement results associated with a current special cell (SpCell) if spCelllnclusion is configured.

[0035] The time domain behavior of an LTM-CSI-ReportConfig may be indicated by the higher layer parameter Itm-ReportConfigType, and may be set to 'aperiodic', 'semiPersistentOnPUCCH', ' semiP ersistentOnPUS CH', or 'periodic.' For 'periodic' and 'semiPersistentOnPUCCH' / ' semiP ersistentOnPUS CH' channel state information (CSI) reporting, the configured periodicity and slot offset may apply in the numerology of the UL bandwidth part (BWP) in which the CSI report is configured to be transmitted on.

[0036] A set of LTM CSI report configurations containing one or more CSI reporting configurations (e.g, LTM-CSI-ReportConfigC), separately from the legacy CSI reporting configuration i.e., used for serving cell beam management and CSI acquisition), may be configured. Each of the CSI reporting configurations (z. e. , LTM and legacy) may have its own identifier (ID) space (e.g, report configuration identity), running from 0 to a predetermined number. As an example, legacy CSI reporting may refer to CSI reporting (serving cell CSI reporting).

[0037] The UE may be configured with one or more CSI reporting configurations, where each reporting configuration may include a LTM CSI resource configuration containing the information of resources to be used for channel measurements (e.g, Ll-reference signal received power (RSRP) measurements). A LTM resource configuration may contain SSBs from one or more candidate cells. For each reporting configuration, the UE may be configured to report M beams from each of the L configured candidate cells i.e., each LTM CSI Resource Setting (LTM-CSI- ResourceConfig) may contain configuration of a LTM-CSI-SSB-ResourceSet whichincludes a list of Z > 1 synchronization signal (SS)Zphysical broadcast channel (PBCH) blocks indices (given by Itm-CSI-SSB-ResourceList) and a list of Z LTM- Candidatelds (given by Itm-CandidatelDList) referring to candidate cells associated with the SS / PBCH block indices). For each candidate cell, the UE may determine the time domain behavior of a SS / PBCH block resource from ssb-Periodicity and ssb- PositionsInBurst. The frequency domain behavior of a SS / PBCH block resource may be determined by the higher layer parameters subCarrierSpacing, ssbFrequency.

[0038] If a UE is configured with an LTM-CSI-ReportConfig, and if the UE is configured with spCelllnclusion, the UE may report in a single reporting instance noOfReportedRS-PerCell different SSBRI for the current SpCell, and each of the noOfReportedCells -1 candidate cells. Otherwise, the UE may report in a single reporting instance noOfReportedRS-PerCell different SS / PBCH block resource indicator (SSBRI) for each of the noOfReportedCell candidate cells, wherein SSBRI k k > 0) corresponds to the configured (£+1 )-th entry of the associated Itm-CSI-SSB- ResourceList in the corresponding LTM-CSI-SSB-ResourceSet.

[0039] If spCelllnclusion is configured, SSB resources in Itm-CSI-SSB-ResourceList associated with the current SpCell may be the entries where physical cell identity (PCI) and frequency information e.g, given by SSB frequency) of the associated candidate cell (given in Itm-CandidateldList) is equal to the PCI and frequency information (given by SSB frequency) of the current SpCell.

[0040] For gNB scheduled LI measurement reporting for Rel-18, LTM may support reporting as UCI; similarly, SP reporting may be supported on PUS CH, and aperiodic reporting may be supported on PUSCH. In a single report instance, reports for serving cells and candidate cells for intra-frequency and / or inter-frequency may be included.

[0041] For beam selection for SSB based Ll-RSRP measurement reports, beam selection may be performed across the L cells from configured (or activated, if introduced) cells (z. e. , M beams for each of the L cells). M x L beams may be reported in a single report instance. Maximum values of M and L may be based on UE capability, and at least M x L=4 may be supported as a UE capability. The values of M and L may be configured in the UE in the reporting configuration. In addition,periodic and SP reporting on PUCCH may be supported for gNB scheduled Ll- measurement reporting. For the beam selection for SSB based Ll-RSRP measurement report, the inclusion of current SpCell in the LI measurement report may be configurable.

[0042] For beam selection for SSB based Ll-RSRP measurement report, for the value of M, L, the RRC configured candidate values may be M = 1, 2, 3, 4, and L = 1, 2, 3, 4. The UE capability may determine the maximum values of M*L and combination of M and L.

[0043] Absolute values and differential values may be used for Ll-RSRP reporting. For absolute Ll-RSRP, the Ll-RSRP value may quantized to a 7 -bit value in the range [-140, -44] decibel-milliwatts (dBm) with 1 decibel (dB) step size. For differential Ll-RSRP, the Ll-RSRP value may be quantized to a 4-bit value, where the differential Ll-RSRP value may be computed with 2 dB step size from a reference Ll-RSRP value.

[0044] SSBRI among configured candidate cells may be included for each Ll-RSRP report. The bit size of SSBRI may be [log2( / CsSSB)l, where / CsSSBis the number of configured SSBs in the corresponding resource set for the report. The following format may be used for reporting:

[0045] Information element (IE) LTM-CSI-ReportConfig may be used to configure reports on the cell in which the LTM-CSI-ReportConfig is included. IE LTM-CSI- ReportConfig may be configured as follows:- ASN1START- TAG-LTM-CSI-REPORTCONFIG-STARTLTM-CSI-ReportConfig-rl8 ::= SEQUENCE {Itm-CSI-ReportConfigld-rl 8 LTM-CSI-ReportConfigld-rl 8 ltm-ResourcesForChannelMeasurement-rl8 LTM-CSI-ResourceConfigId-rl8 ltm-ReportConfigType-rl8 CHOICE { periodic-rl8 SEQUENCE { reportSlotConfig-rl 8 CSI- ReportPeriodicity AndOffset, pucch-CSI-ResourceList-rl8 SEQUENCE (SIZE (L.maxNrofBWPs)) OF PUCCH-CSI-Resource}, semiPersistentOnPUCCH-rl8 SEQUENCE {reportSlotConfig-rl 8 CSI- ReportPeriodicity AndOffset, pucch-CSI-ResourceList-rl8 SEQUENCE (SIZE (L.maxNrofBWPs)) OF PUCCH-CSI-Resource},},Itm-ReportContent-rl 8 LTM-ReportContent-rl 8LTM-ReportContent-rl8 ::= SEQUENCE { noOfReportedCells-rl8 ENUMERATED {nl,n2,n3,n4} noOfReportedRS-PerCell-rl8 ENUMERATED {nl,n2,n3,n4} spCellInclusion-rl8 ENUMERATED {true} OPTIONAL, - Need R}- TAG-LTM-CSI-REPORTCONFIG-STOP- ASN1STOP

[0046] LTM-CSI-ReportConfig may also include the following field descriptions:

[0047] The IE LTM-CSI-ResourceConfig may define a group of one or more CSI resources for an LTM candidate cell configuration. IE LTM-CSI-ResourceConfig may be configured as follows:- ASN1START- TAG-LTM-CSI-RESOURCECONFIG-STARTLTM-CSI-ResourceConfig-rl8 ::= SEQUENCE { ltm-CSI-ResourceConfigId-rl8 LTM-CSI-ResourceConfigld-rl 8, ltm-CSI-SSB-ResourceSet-r!8 LTM-CSI-SSB-ResourceSet-rl8,LTM-CSI-SSB-ResourceSet-rl8 ::= SEQUENCE { ltm-CSI-SSB-ResourceSetId-rl8 LTM-CSI-SSB-ResourceSetId-rl8, ltm-CSI-SSB-ResourceList-rl8 SEQUENCE (SIZE (l..maxNrofLtmCSI-SSB-ResourcesPerSet-rl8)) OF SSB-Index,Itm-CandidateldList-rl 8 SEQUENCE (SIZE (l..maxNrofLtmCSI-SSB-ResourcesPerSet-rl8)) OF LTM-Candidateld-rl8- TAG-LTM-CSI-RESOURCECONFIG-STOP- ASN1STOP

[0048] IE LTM-CSI-ResourceConfig may also include the following field descriptions:

[0049] For SP reporting on PUCCH, the PUCCH resource used for transmitting the CSI report may be configured by reportConfigType. SP reporting on PUCCH may be activated by an activation command, which may select one of the SP reporting settings for use by the UE on the PUCCH. When the UE would transmit a PUCCH with hybrid automatic repeat request (HARQ)-acknowledgement (ACK) information in slot n corresponding to the physical data shared channel (PDSCH) carrying the activation command, the indicated SP reporting setting may be applied starting from the first slot that is after slot n +where p is the subcarrier spacing (SCS) configuration for the PUCCH.

[0050] A UE may perform SP CSI reporting on the PUCCH applied starting from the first slot that is after slot n + 3Nslot subframe, p when the UE would transmit a PUCCH with HARQ-ACK information in slot n corresponding to the PDSCH carrying the activation command, where p is the SCS configuration for the PUCCH. The activation command may contain one or more reporting settings where the associated CSI resource settings are configured.

[0051] FIG. 2 illustrates an example of a SP CSI reporting on PUCCH activation / deactivation MAC CE. The SP CSI reporting on PUCCH activation / deactivation MAC CE may be identified by a MAC subheader with logical channel ID (LCID) of value 25. It may have a fixed size of 16 bits, and include several fields, such as serving cell ID. This field may indicate the identity of the serving cell for which the MAC CE applies; the length of the field may be 5 bits. The MAC subheader may alsoinclude a BWP ID field indicating a UL BWP for which the MAC CE applies as the codepoint of the DCI bandwidth part indicator field; the length of the BWP ID field may be 2 bits. The MAC subheader may also include a Si field indicating the activation / deactivation status of the SP CSI report configuration within csi- ReportConfigToAddModList. So may refer to the report configuration which may include PUCCH resources for SP CSI reporting in the indicated BWP, and may have the lowest CSI-ReportConfigld within the list with type set to semiP ersistentOnPUCCH, Si to the report configuration which includes PUCCH resources for SP CSI reporting in the indicated BWP and has the second lowest CSI- ReportConfigld, and so on. If the number of report configurations within the list with type set to semiP ersistentOnPUCCH in the indicated BWP is less than i + 1, MAC entity may ignore the Si field. The Si field may be set to 1 to indicate that the corresponding SP CSI report configuration may be activated. The Si field may be set to 0 to indicate that the corresponding SP CSI report configuration i shall be deactivated. The MAC subheader may also include a reserved bit R set to 0.

[0052] The reporting configuration for a LTM report {e.g. , including the configuration of SpCell inclusion (SpCelllnclnsion)) indicating whether current SpCell measurements to be included in the report or not, and the associated resource configuration which may include the resource signal information of one or more candidate cells to be considered for measurement and reporting, may be provided in the RRC configuration. There may be a limited number of RRC configured report configurations for dynamically activated / triggered LTM reporting {e.g, SP reporting on PUCCH (up to 4), SP reporting on PUS CH, aperiodic reporting). As the UE moves, there may be a need to update the configuration of a RRC configured reporting configuration {e.g, the candidate cells to be considered for measurement and reporting). With a limited number of RRC configured report configurations, any update may require RRC reconfiguration, which is a slower process.

[0053] Certain example embodiments described herein may have various benefits and / or advantages to overcome the disadvantages described above. For example, certain example embodiments may provide solutions for the UE to dynamically update theresource configuration for a CSI report configuration for LTM. Thus, certain example embodiments discussed below are directed to improvements in computer-related technology.

[0054] Certain example embodiments may enable dynamically updating resource configurations, including configurations containing the reference signal resource from one or more candidate cells to be considered for measurement and reporting, for one or more (e.g, LTM) CSI reporting configurations. Some example embodiments may be provided for SP (e.g, LTM) CSI reporting on PUCCH, SP (e.g, LTM) CSI reporting on PUSCH, and / or aperiodic reporting on PUSCH. In any of the example embodiments described herein, updating resource configurations for reporting configurations may be provided for serving cell CSI reporting (e.g, for beam management). Various example embodiments may be used for and / or applied to various CSI reporting configurations (e.g, A / SP / P CSI reporting on PUCCH, A / SP / P LTM CSI reporting on PUCCH, A / SP / P CSI reporting on PUSCH, A / SP / P LTM CSI reporting on PUSCH).

[0055] FIG. 3 illustrates an example of a signaling diagram 300 for supporting periodic and SP reporting on PUCCH. UE 320 may be similar to UE 820, and source cell 330, CU 340, and target cell 350 may be similar to NE 810, as illustrated in FIG. 8, according to certain example embodiments.

[0056] At operation 301, UE 320 may transmit L3 measurements to CU 340.

[0057] At operation 302, source cell 330 and CU 340 may perform LTM preparation, including preparing LTM resource configurations and / or LTM report configurations.

[0058] At operation 303, CU 340 may transmit to UE 320 an RRC reconfiguration message.

[0059] At operation 304, UE 320 may transmit an RRC reconfiguration complete message to CU 340.

[0060] At operation 305, source cell 330 may transmit, to UE 320, a MAC CE LTM SP on PUCCH activation of a first report configuration indicating no changes to resource configuration.

[0061] At operation 306, UE 320 may consider SSBs of source cell 330, CU 340, and / or target cell 350 for measurements and / or reporting.

[0062] At operation 307, UE 320 may transmit L 1 measurement reporting to source cell 330. For example, UE 320 may transmit selected measurements for source cell 330, CU 340, and target cell 350.

[0063] At operation 308, source cell 330 may transmit to UE 320 a MAC CE SP on PUCCH activation of reporting configuration 1, indicating a change to a resource configuration, and that either source cell 330 or target cell 350 should be selected.

[0064] In certain example embodiments, the signaling to activate, update, and / or trigger a dynamic LTM CSI reporting may be used to dynamically update the resource configuration for the one or more reports being activated / triggered. The signaling may also be used to deactivate at least one (or all) reporting configurations. In various example embodiments, the CSI reporting may include reporting one or more of channel quality indicator (CQI), precoding matrix indicator (PMI), CSI-RS resource indicator (CRI), SS / PBCH block resource indicator (SSBRI), layer indicator (LI), rank indicator (RI), Ll-RSRP, Ll-signal-to-interference-plus-noise ratio (SINR), or Capability Index.

[0065] In some example embodiments, when the signaling of SP reporting on PUCCH for LTM is conveyed in a MAC CE (z.e., a field in a MAC CE indicates whether the activation / deactivation of one or more SP reporting configuration applies for LTM configuration or serving cell configuration), the MAC CE (z.e., SP LTM CSI reporting on PUCCH activation / deactivation MAC CE) may be used to dynamically update the configuration of the resource configuration (e.g, reference signal resource to be considered for measurement and reporting) of one or more SP reporting configurations being activated.

[0066] In various example embodiments, resources of one or more LTM candidate cells may be removed (configured for not considering) for measurement and reporting from the RRC configured resource configuration set associated with a SP CSI reporting being activated. For example, for a SP CSI reporting on PUCCH configuration, an associated resource configuration in RRC configuration may contain [SSB 1 of cell 1, SSB 2 ofcell 1, SSB 1 of cell 2, SSB 2 of cell 3, SSB 3 of cell 3, SSB 4 of cell 3], With a MAC CE SP LTM CSI activation / deactivation command, the resource configuration may be updated to [SSB 1 of cell 2, SSB 2 of cell 3, SSB 3 of cell 3, SSB 4 of cell 3] by indicating the removal of cell 1. Thus, UE 320 may only consider indicated resources of cell 2 and cell 3 for measurement and reporting.

[0067] FIG. 3 illustrates an example where new bit fields Ci (Co to C7) may be added. Each bit field may indicate a configuration for a candidate cell (e.g, Cnrepresents the configuration for candidate cell ‘n’ (LTM Candidate Cell ID = n)). Alternatively, the candidate cells IDs may be mapped to the Cn(e.g, starting from Co) fields in order of the LTM candidate IDs (e.g, ascending order). In one example, if the value of any Ci bit field (i = 0 to 7) is set to a first value (e.g, ‘0’), then resources of that candidate cell may not be considered for measurement and reporting, regardless of whether any resources are present or not in the resource configuration). In one example, if the value of any Ci bit field (e.g. , i = 0 to 7) is set to a first value (e.g. , ‘0’), then resources of that candidate cell may not be considered for measurement and reporting (z. e. , the resources corresponding to candidate cells may be configured by RRC but activated using the Ci field(s)). Otherwise, if the value of any Ci field (i = 0 to 7) is set to a second value (e.g, ‘ 1’), then there may be no change in the resource configuration associated with candidate cell provided in the RRC configuration. Alternatively, if the value of any Ci field (i = 0 to 7) is set to a second value (e.g, ‘ 1’), and there is a corresponding RRC configuration for the resources, then the resource configuration associated with candidate cell provided in the RRC configuration may be considered for measurement and reporting. Thus, if the value of the Ci field (i = 0 to 7) is set to a ‘ 1 ’ and resource of candidate cell Ci is included in the resource configuration, then those resources may be considered for measurement and reporting, and if resource of candidate cell Ci is not included in the resource configuration, then those resources may not be considered for measurement and reporting. In some alternative example embodiments, each Ci field may correspond to configured resource configurations (e.g, RRC configured). For example, a first C field, such as Co, of Ci fields may correspond to a first RRC configuration of resources, and a second C field, such asCi, of Ci fields may correspond to a second RRC configuration of resources. The first and second resource configurations may include one or more DL RS (e.g, SSB and / or CSI-RS) of one or more cells (e.g, LTM candidate cells, serving cells).

[0068] At operation 309, UE 320 may consider given SSBs of source cell 330, CU 340, and target cell 350 for measurements and / or reporting.

[0069] At operation 310, UE 320 may transmit to source cell 330 LI measurement reporting, including selected measurements for source cell 330 or target cell 350.

[0070] In certain example embodiments with more than one (SP) reporting configuration being activated, a common bit set may be used to update the resource configurations for multiple reporting configurations (e.g, the same configuration to be used for all reporting configurations being activated). Alternatively, different resource configurations may be configured for and / or associated with one or more reporting configurations in separate messages.

[0071] Some example embodiments may include a field including a corresponding set of Ci fields associated with the activation / deactivation fields (fields So. . .Si in FIG. 4). The indication provided by the Ci fields may configure the candidate cell configurations (e.g, for resource configuration) for the associated reporting configuration.

[0072] In various example embodiments, a separate set of bit fields (one for each reporting configuration) may be used for each reporting configuration to update the resource configuration independently, as illustrated in FIG. 5. For example, the Ci field may be used to indicate whether measurements associated with resource configuration / candidate cell Ci should (always) be included in the report. For example, if the value of Ci field is set to ‘1’, UE 320 may be required to report at least one measurement associated with resource configuration / candidate cell Ci in each report associated with the reporting configuration being activated. As an example, each reporting configuration for which the activation is provided or updated (e.g, the Si field in the FIG. 5) may include a bit field including one or more resource configuration activation / deactivation fields (e.g, the octet including Ci fields). The resource configuration fields (e.g, octet including of Ci) for the reporting configurations that are not indicated to be updated (e.g, the Si field is set to first value‘0’) may not be present. In some examples, the resource configuration fields (e.g, octets) may be listed in the order of Si fields for which the update is indicated (e.g, bit is set to second value ‘ 1’). Alternatively, the resource configuration fields may be fixed.

[0073] As another example, in addition to candidate cells, an additional field may be used to indicate whether a resource (e.g, DL RS, SSB, or CSI-RS index) given in the resource configuration is to be considered or not for measurement and reporting.

[0074] In certain example embodiments, for SP LTM CSI reporting on PUSCH, the DCI (e.g, an existing DCI format used to schedule uplink or downlink transmissions or a new CI format that includes one or more fields used for activating / deactivating SP CSI reporting and / or updating resource configurations for reporting) activating or deactivating an SP LTM CSI reporting on PUSCH may be used to update the resource configuration of the SP LTM CSI reporting configuration(s) being activated. For example, a bit field in the DCI (e.g, 8 bit field) may be used to select / update the candidate cells to be considered from the given resource configuration for measurement and reporting. The DCI format that provides the selection / update of resource configurations and / or update of reporting configurations may or may not schedule any transmissions.

[0075] According to some example embodiments, for aperiodic CSI reporting on PUSCH, the DCI (e.g, the DCI format used for enabling an aperiodic CSI reporting trigger state) enabling an aperiodic LTM CSI reporting on PUSCH may be used to update the reporting configuration of the aperiodic LTM CSI reporting configuration s) being enabled. For example, a bit field in the DCI (e.g, 8 bit field) may be used to select / update the candidate cells to be considered from the given resource configuration for measurement and reporting.
