Description

Technical Field

[0001] In 3GPP, Layer 1 (L1) / Layer 2 (L2) triggered mobility (LTM) is a cell switching procedure in which the serving cell of a UE (e.g., a primary cell (PCell) or a primary secondary cell (PSCell)) can be switched by the network by sending an LTM cell switching command. The LTM switching command can be delivered via MAC signaling using a media access control (MAC) control element (CE). Therefore, changes between cells can currently be performed without using radio resource control (RRC) signaling as with L3-based switching. LTM cell switching decisions can be based on measurements (e.g., L1 measurements) that the UE can perform and report (e.g., L1 measurement reports). The measurements and reports can be based on LTM candidate cell configurations provided by the network for one or more LTM candidate cells. LTM candidate cells can include neighboring cells of the UE and / or any current serving cell (e.g., S cell (SCell)). Improvements to LTM procedures and techniques are needed. Background Art

[0002] Examples of mobile or wireless telecommunication systems may include radio frequency (RF) 5G RAT, Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (UTRAN), LTE Evolved UTRAN (E-UTRAN), LTE Advanced (LTE-A), LTE-A Pro, NR access technology and / or MulteFire Alliance. 5G wireless system refers to the next generation (NG) radio system and network architecture. 5G systems are typically built on 5G NR, but 5G (or NG) networks can also be built on E-UTRA radio. It is expected that NR can support service categories such as enhanced mobile broadband (eMBB), ultra-reliable low-latency communication (URLLC) and massive machine type communication (mMTC). NR is expected to deliver extreme broadband, ultra-robust, low-latency connectivity and large-scale networking to support the Internet of Things (IoT). The next generation radio access network (NG-RAN) represents a radio access network (RAN) for 5G, which can provide radio access for NR, LTE and LTE-A. Note that a node in 5G that provides radio access functions to user equipment (e.g., similar to a Node B in UTRAN or an evolved Node B (eNB) in LTE) may be referred to as a next-generation Node B (gNB) when built on an NR radio, and may be referred to as a next-generation eNB (NG-eNB) when built on an E-UTRA radio.

[0027] It will be readily appreciated that the components of certain exemplary embodiments as generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations. Therefore, the following detailed description of some exemplary embodiments of systems, methods, apparatuses, and computer program products for supporting aperiodic, periodic, and SP reporting on PUCCH / PUSCH or using MAC CE is not intended to limit the scope of certain exemplary embodiments, but is representative of selected exemplary embodiments.

[0028] In 3GPP, LTM is a cell switching procedure in which the serving cell of a UE (e.g., a primary cell (PCell) or a primary secondary cell (PSCell)) can be switched by the network by sending an LTM cell switching command. The LTM switching command can be delivered via MAC signaling using MACCE. Therefore, changes between cells can currently be performed without RRC signaling as with L3-based switching. LTM cell switching decisions can be based on measurements (e.g., L1 measurements) that the UE can perform and report (e.g., L1 measurement reports). The measurements and reports can be based on the LTM candidate cell configuration provided by the network for one or more LTM candidate cells. LTM candidate cells can include neighboring cells of the UE and / or any current serving cell (e.g., SCell).

[0029] Before cell switching, the network may optionally activate one or more transmission configuration indicator (TCI) states of one or more candidate cells. Once the candidate cell TCI states are activated, the UE may track the timing of the activated TCI states. The UE may also perform early uplink (UL) synchronization before cell switching (if requested by the network).

[0030] Figure 1 An example of an LTM process is described. In step 1, the UE may send a MeasurementReprot message to the gNB (i.e., base station). The gNB may determine to configure LTM and initiate candidate cell preparation. In step 2, the gNB may send an RRCReconfiguration message to the UE, including an LTM candidate cell configuration for at least one candidate cell. In step 3, the UE may store the LTM candidate cell configuration and send an RRCReconfigurationComplete message to the gNB.

[0031] In step 4a, the UE may perform DL synchronization with the candidate cell before receiving the cell switching command. In step 4b, the UE may perform early timing advance (TA) acquisition with the candidate cell requested by the network before receiving the cell switching command. For example, this can be performed by a contention-free random access (CFRA) triggered by a physical downlink control channel (PDCCH) command from the source cell. The UE may then send a preamble to the indicated candidate cell. In order to minimize data interruption of the source cell due to CFRA toward the candidate cell, the UE may not receive a random access response (RAR) for TA value acquisition purposes. The TA value of the candidate cell may be indicated in the cell switching command. The UE may not maintain a TA timer for the candidate cell and may instead rely on network implementation to ensure TA validity.

[0032] In step 5, the UE may perform L1 measurements on the configured candidate cells and may send a low layer measurement report to the gNB. In step 2, measurements, such as L1 measurements, may be performed according to the RRC reconfiguration. In step 6, the gNB may determine to perform a cell handover to the target cell and may send a MAC CE triggering a cell handover by including a candidate configuration index of the target cell. The UE may switch to the target cell and apply the configuration indicated by the candidate configuration index.

[0033] In step 7, if the UE does not have a valid TA for the target cell, the UE may perform a random access procedure for the target cell.

[0034] In step 8, the UE may complete the LTM cell switching procedure (e.g., by sending an RRCReconfigurationComplete message to the target cell). If the UE performed the RA procedure in step 7, the UE may consider the LTM execution to be successfully completed when the random access procedure is successfully completed. For LTM without a random access channel (RACH), the UE may consider the LTM execution to be successfully completed when the UE determines that the network has successfully received its first UL data. The UE may determine the successful reception of its first UL data by receiving a PDCCH addressed to the cell radio network temporary identifier (C-RNTI) of the UE in the target cell, which may schedule new transmissions after the first UL data. Note that steps 4-8 may be performed multiple times for subsequent LTM cell switching using the LTM candidate cell configuration provided in step 2.

[0035] In LTM, the UE can perform a MAC reset. Using RRC signaling, the network can control whether the UE performs radio link control (RLC) reestablishment and packet data convergence protocol (PDCP) data recovery during cell handover. The PDCP data recovery procedure can be applied to RLC acknowledged mode (AM) data radio bearer (DRB) for distributed unit (DU) LTM cell switching.

[0036] For LTM, information about measurement resources (e.g., synchronization signal blocks (SSBs) 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 an L1 measurement report configuration, in which the UE may report measurements. For LTM, periodic and SP reporting on PUCCH, SP reporting on the physical uplink shared channel (PUSCH), and aperiodic reporting on PUSCH may be supported.

[0037] Each reporting setting (e.g., LTM-CSI-ReportConfig) can be associated with an LTM resource configuration for channel measurement and can include parameters for time domain behavior (i.e., periodic, SP reporting on PUCCH, SP reporting on PUSCH, non-periodic reporting on PUSCH) provided by ltm-ReportConfigType, the number of candidate cells and the number of reference signals for each candidate cell provided by noOfReportedCells and noOfReportedRS-PerCell, respectively, and if spCellInclusition is configured, the L1 measurement results associated with the current special cell (SpCell).

[0038] The time domain behavior of LTM-CSI-ReportConfig may be indicated by the higher layer parameter ltm-ReportConfigType and may be set to "aperiodic", "semiPersistentOnPUCCH", "semiPersistentOnPUSCH" or "periodic". For "periodic" and "semiPersistentOnPUCCH" / "semiPersistentOnPUSCH" CSI reports, the configured periodicity and slot offset may be applied to the parameter set in which the CSI report is configured to be sent as the UL bandwidth part (BWP).

[0039] A set of LTM CSI reporting configurations containing one or more CSI reporting configurations (e.g., LTM-CSI-ReportConfigs) may be configured separately from the legacy CSI reporting configurations (i.e., for serving cell beam management and CSI acquisition). Each CSI reporting configuration (i.e., LTM and legacy CSI) may have its own identifier (ID) space (e.g., reporting configuration identifier), from 0 to a predetermined number. As an example, a legacy CSI report may refer to a CSI report (serving cell CSI report).

[0040] The UE may be configured with one or more CSI reporting configurations, where each reporting configuration may include an LTM CSI resource configuration containing information of resources to be used for channel measurements (e.g., L1-reference signal received power (RSRP) measurements). The 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 a configuration of an LTM-CSI-SSB-ResourceSet, which includes a list of Z ≥ 1 synchronization signal (SS) / physical broadcast channel (PBCH) block indices (given by the ltm-CSI-SSB-ResourceList) and a list of Z LTM-CandidateIDs (given by the ltm-CandidateID List) relating to the candidate cells associated with the SS / PBCH block indices). For each candidate cell, the UE may determine the time domain behavior of the SS / PBCH block resources based on the ssb-Periodicity and ssb-PositionsInBurst. The frequency domain behavior of the SS / PBCH block resources may be determined by higher layer parameters subCarrierSpacing (subcarrier spacing), ssbFrequency (ssb frequency).

[0041] If the UE is configured with LTM-CSI-ReportConfig and if the UE is configured with spCellInclusion, the UE may report noOfReportedRS-PerCell different SSBRIs for the current SpCell and each of NoOfReportedCells-1 candidate cells in a single reporting instance. Otherwise, the UE may report noOfReportedRS-PerCell different SS / PBCH block resource indicators (SSBRIs) for each of NoOfReportedCells candidate cells in a single reporting instance, where SSBRI k (k≥0) corresponds to the configured (k+1)th entry of the associated ltm-CSI-SSB-ResourceList in the corresponding LTM-CSI-SSB-ResourceSet.

[0042] If spCellInclusion is configured, the SSB resources in the ltm-CSI-SSB-ResourceList associated with the current SpCell can be an entry where the physical cell identifier (PCI) and frequency information (e.g., given by the SSB frequency) of the associated candidate cell (given in the ltm-CandidateId List) are equal to the PCI and frequency information (given by the SSB frequency) of the current SpCell.

[0043] For L1 measurement reporting scheduled by gNB in ​​Rel-18, LTM can support reporting as UCI; similarly, SP reporting can be supported on PUSCH, and aperiodic reporting can be supported on PUSCH. In a single reporting instance, reports for serving cells and candidate cells for intra-frequency and / or inter-frequency can be included.

[0044] For beam selection for SSB based L1-RSRP measurement reporting, beam selection may be performed across L cells from the configured (or activated, if introduced) cells (i.e., M beams for each of the L cells). M×L beams may be reported in a single reporting instance. The maximum values ​​of M and L may be based on UE capabilities, and at least M×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. Additionally, periodic and SP reporting on PUCCH for gNB scheduled L1-measurement reporting may be supported. For beam selection for SSB based L1-RSRP measurement reporting, it is configurable to include the current SpCell in the L1 measurement report.

[0045] For beam selection based on SSB-based L1-RSRP measurement report, for the values ​​of M and L, the RRC configuration candidate values ​​can be M=1, 2, 3, 4, and L=1, 2, 3, 4. The UE capability can determine the maximum value of M*L and the combination of M and L.

[0046] Absolute and differential values ​​can be used for L1-RSRP reporting. For absolute L1-RSRP, the L1-RSRP value can be quantized as a 7-bit value in the range of [-140, -44] decibel milliwatts (dBm) with a 1 decibel (dB) step size. For differential L1-RSRP, the L1-RSRP value can be quantized as a 4-bit value, where the differential L1-RSRP value can be calculated from the reference L1-RSRP value in 2dB steps.

[0047] For each L1-RSRP report, the SSBRI of the configured candidate cells may be included. The bit size of the SSBRI may be in is the number of SSBs configured in the corresponding resource set for reporting. The following formats can be used for reporting:

[0048]

[0049]

[0050] The information element (IE) LTM-CSI-ReportConfig may be used to configure a report on the cell in which the LTM-CSI-ReportConfig is included. The IE LTM-CSI-ReportConfig may be configured as follows:

[0051]

[0052] LTM-CSI-ReportConfig may also include the following field descriptions:

[0053]

[0054] IE LTM-CSI-ResourceConfig can define one or more CSI resource groups for LTM candidate cell configuration. IE LTM-CSI-ResourceConfig can be configured as follows:

[0055]

[0056] IE LTM-CSI-ResourceConfig may also include the following field descriptions:

[0057]

[0058]

[0059] For SP reporting on PUCCH, the PUCCH resource used to send CSI reports can be configured by reportConfigType. SP reporting on PUCCH can be activated by an activation command, which can select one of the SP reporting settings for the UE to use on PUCCH. When the UE is to send a PUCCH with hybrid automatic repeat request (HARQ)-acknowledgement (ACK) information in the time slot n corresponding to the physical data shared channel (PDSCH) carrying the activation command, it can select from the time slot The indicated SP reporting setting applies starting from the first time slot after (subframe), where μ is the subcarrier spacing (SCS) configuration of PUCCH.

[0060] When the UE will send a PUCCH with HARQ-ACK information in slot n corresponding to the PDSCH carrying the activation command, the UE may perform SP CSI reporting on the PUCCH that applies starting from the first slot after slot n+3Nslot subframe,μ, where μ is the SCS configuration of the PUCCH. The activation command will contain one or more report settings with the associated CSI resource settings configured.

[0061] Figure 2 An example of an activation / deactivation MAC CE for SP CSI reporting on PUCCH is shown. The activation / deactivation MAC CE for SP CSI reporting on PUCCH can be identified by a MAC subheader with a logical channel ID (LCID) value of 25. It can have a fixed size of 16 bits and include several fields, such as serving cell ID: this field can indicate the identification of the serving cell to which the MAC CE applies; the length of this field can be 5 bits. The MAC subheader can also include a BWP ID field, which indicates that the MAC CE applies the UL BWP as the code point of the DCI bandwidth part indicator field; the length of the BWPID field can be 2 bits. The MAC subheader can also include an S-ReportConfigToAddModList field indicating the activation / deactivation status of the SP CSI reporting configuration within the csi-ReportConfigToAddModList. i field. S0 refers to a reporting configuration that may include PUCCH resources for SP CSI reporting in the indicated BWP and may have the lowest CSI-ReportConfigId in the list with its type set to Semi PersistentOnPUCCH, S1 refers to a reporting configuration that includes PUCCH resources for SP CSI reporting in the indicated BWP and has the second lowest CSI-ReportConfigId, and so on. If the number of reporting configurations in the list with the type set to SemiPersistentOnPUCCH in the indicated BWP is less than i+1, the MAC entity may ignore the S field. i Field. i The S field may be set to 1 to indicate that the corresponding SP CSI reporting configuration may be activated. i The field may be set to 0 to indicate that the corresponding SP CSI reporting configuration i should be deactivated. The MAC subheader may also include a reserved bit R set to 0.

[0062] For LTM, a set of LTM CSI reporting configurations separate from the legacy CSI reporting configurations used for intra-cell / inter-cell beam management and serving cell CSI acquisition (i.e., the legacy CSI reporting for serving cells in this document) may support Rel-18 LTM. The LTM CSI reporting configuration and the legacy CSI reporting configuration may have their own (i.e., independent) configuration identifier space to indicate the corresponding reporting configurations (i.e., the LTM-CSI-ReportConfigId (LTM-CSI-reporting configuration Id) used to specifically represent the LTM CSI reporting configuration has a value from 0 to a maximum value (M1 = maximum number of LTM CSI reporting configurations), and the CSI-ReportConfigId (CSI-reporting configuration Id) used to specifically represent the legacy CSI reporting configuration has a value from 0 to a maximum value (M2 = maximum number of CSI reporting configurations).

[0063] Semi-persistent reporting on PUCCH for CSI reporting of both LTM and serving cell (e.g., legacy or beam managed) may be supported. For serving cell semi-persistent reporting on PUCCH, a MAC-CE may be used for activation / deactivation of semi-persistent reporting on PUCCH by indicating the CSI reporting configuration ID or multiple IDs to be activated and / or deactivated. If the same MAC-CE command is used for LTM semi-persistent reporting on PUCCH, the UE may not be able to determine whether a given MAC-CE is a serving cell (i.e., legacy) CSI report or for LTM CSI reporting. In various example embodiments, a legacy CSI report may refer to a CSI report (e.g., a serving cell CSI report).

[0064] A reporting configuration for LTM reporting is provided in the RRC configuration (e.g., including a configuration for SpCellInclusion indicating whether the current SpCell measurement is to be included in the report, and an associated resource configuration including resource signal information of one or more candidate cells to be considered for measurement and reporting). In addition, there may be a limited number of RRC configured reporting configurations for dynamically activated / triggered LTM reporting (SP reporting on PUCCH (e.g., up to 4), SP reporting on PUSCH, non-periodic reporting). When the UE moves, the configuration of the RRC configured reporting configuration may need to be updated. In the case of a limited number of RRC configured reporting configurations, any update may require RRC reconfiguration, which is a slower process.

[0065] Certain exemplary embodiments described herein may have various benefits and / or advantages to overcome the above disadvantages. For example, certain exemplary embodiments may provide a solution for a UE to determine whether a given MAC-CE for activation / deactivation of SP CSI reporting on a PUCCH (or PUSCH) is for serving cell CSI reporting or for LTM CSI reporting. In addition, some exemplary embodiments may dynamically update the reporting configuration of the CSI reporting configuration for LTM. Therefore, certain exemplary embodiments discussed below are directed to improvements in computer-related technologies.

[0066] Certain example embodiments may provide a signaling method to indicate to a UE whether activation / deactivation of one or more SP reports on a PUCCH configuration applies to an LTM reporting configuration or a serving cell reporting configuration (e.g., a traditional report for serving cell CSI). Some example embodiments may also provide a signaling method to dynamically update a reporting configuration for LTM CSI reporting (i.e., a configuration for including current serving cell (e.g., SpCell) measurements in each report, a configuration for one or more LTM CSI reporting configurations to be activated / triggered). In addition, various example embodiments may provide a method for determining whether to perform or not perform reporting on one or more SP reporting configurations for legacy serving cell BM / CSI when one or more LTM SP reports on a PUCCH are activated or deactivated. In various example embodiments, the CSI report may include reporting one or more of the following: 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), L1-RSRP, L1-SINR signal interference plus noise ratio, or Capability Index.

[0067] Figure 5 An example of a signaling diagram 500 for an activation / deactivation MAC CE with a serving cell / LTM (S / L) field is shown. According to certain example embodiments, UE 510 may be similar to UE 1020, and source cell 520, CU 530, and target cell 540 may be similar to NE 1010, such as Fig.10 As shown in . S / L or S / L field may refer to serving cell CSI report / LTM CSI report.

[0068] At operation 501 , the CU 530 may transmit an RRC reconfiguration message to the UE 510 .

[0069] At operation 502 , the UE 510 may transmit an RRC reconfiguration complete message to the CU 530 .

[0070] At operation 503, the source cell 520 may send a MAC CE to the UE 510, with one or more report configurations S0 ... S i Activation of SP on the PUCCH of the UE, where the S / L field can be set to a value indicating LTM. Alternatively, the S / L field (or a field in a downlink control message, such as a MAC CE) can be set to a value indicating a serving cell CSI report.

[0071] In various example embodiments, SP reporting, PUCCH and / or PUSCH CSI reporting may be used (ie, PUCCH and PUSCH may be used interchangeably). Alternatively, SP reporting may be used for MAC CE CSI reporting.

[0072] In any examples herein, CSI reporting herein may refer to any time type, such as semi-persistent, periodic, or aperiodic.

[0073] In certain example embodiments, signaling for SP reporting on PUCCH for LTM (i.e., activation and / or deactivation of reporting configurations) may be transmitted in a MAC CE, wherein a field in the MAC CE indicates whether the activation / deactivation of one or more SP reporting configurations is applicable to an LTM reporting configuration or a serving cell reporting configuration (e.g., for legacy reporting of serving cell beam management (BM) and CSI). For example, an identifier may be used to specifically identify an activation / deactivation MAC-CE command for SP LTM CSI reporting on PUCCH. A special logical channel ID (LCID) and / or a special extended LCID (eCCID) may be used in the MAC subheader to specifically indicate that the MAC CE is for activation / deactivation of SP LTM CSI reporting on PUCCH. For example, an LCID value different from the LCID used for SP CSI reporting on legacy PUCCH may indicate that the MAC CE is for LTM CSI reporting. Therefore, the UE can read the (e)LCID field of the MAC CE to determine whether the activation or deactivation of the reporting configuration (or any other information provided by the MAC CE) is for serving cell CSI reporting or for LTM CSI reporting.

[0074] Alternatively, a field in a downlink control message (e.g., DCI / MAC CE) may be used, such as Figure 3The bit field shown in (e.g., S / L) is used to distinguish whether the MAC CE is used for traditional SP CSI reporting or for LTM SP CSI reporting. If the field indicates S (or indicates a first value or indicates a value indicating serving cell beam management), the activation / deactivation can be used for serving cell beam management (e.g., for intra-cell / inter-cell beam management or / and CSI acquisition). Alternatively, if the field indicates L (or indicates a second value or indicates a value indicating LTM), the activation / deactivation can be used for LTM CSI reporting. S can be represented by 0 (e.g., the first value) and L can be represented by "1" (e.g., the second value), or vice versa. A field in a downlink control message (e.g., DCI or MAC CE message) may include a field indicating whether the information provided by the control message (e.g., DCI or MAC CE) is for traditional CSI reporting or LTM CSI reporting.

[0075] At operation 504, the UE 510 may determine that the S / L field value indicates LTM, and may apply the reporting configuration to one or more reporting configurations S0 . . . S i .

[0076] In certain example embodiments, when UE 510 determines that a given MAC-CE is an activation / deactivation MAC-CE command for (SP) LTM CSI reporting on PUCCH, UE 510 may determine S i The field indicates the activation / deactivation status of the SP CSI reporting configuration within the RRC configured reporting configuration list for LTM (e.g., ltm-csi-ReportConfigToAddModeList). S0 may refer to a reporting configuration that may include PUCCH resources for SP CSI reporting in the indicated BWP and may have the lowest reporting configuration identifier (LTM-CSI-ReportConfigId in the list with type set to semiPersistentOnPUCCH), S1 may be set to a reporting configuration that includes PUCCH resources for SP CSI reporting in the indicated BWP and has the second lowest reporting configuration identifier (LTM-CSI-ReportConfigId), and so on. If the number of reporting configurations in the list (type set to SemiPersistentOnPUCCH) in the indicated BWP is less than i+1, the MAC entity may ignore the S i Field. S is set to 1 i The field may indicate that the corresponding SP CSI reporting configuration i may be activated. The Si field may be set to 0 to indicate that the corresponding SP CSI reporting configuration i may be deactivated.

[0077] At operation 505, UE 510 may send a (L1) measurement report to source (serving) cell 520, which may be based on one or more reporting configurations S0 ... S i of.

[0078] Figure 6A-6B An example of a signaling diagram 600 for SP cell inclusion (with activation / deactivation MAC CE of SP) is shown. According to certain exemplary embodiments, UE 610 may be similar to UE 1020, and source cell 620, CU 630, and target cell 640 may be similar to NE 1010, such as Fig.10 as shown in .

[0079] At operation 601 , the CU 630 may transmit an RRC reconfiguration message to the UE 610 .

[0080] At operation 602 , the UE 610 may transmit an RRC reconfiguration complete message to the CU 630 .

[0081] Certain example embodiments may include signaling configured to control the inclusion of SpCell measurements and / or reporting of SpCell measurements in a reporting configuration or multiple configurations. In some example embodiments, the signaling (i.e., control message) for activating / deactivating, triggering and / or updating LTM CSI reporting may also include an indication configured to (dynamically) control / change the reporting configuration (i.e., control / change the reported information) for being activated / triggered. In some example embodiments, the indication may indicate whether SpCell measurements are included for one or more activated CSI reporting configurations. In various exemplary embodiments, the inclusion or control of the inclusion of SpCell measurements or SpCell information in the reporting configuration may be indicated by a field in a downlink control message. For example, the field may be present in a MAC CE or a DCI message. For example, at operation 603, the source cell 620 may send a MAC CE for SP activation on the PUCCH for the reporting configuration to the UE 610. For example, S0 may be related to the first LTM reporting configuration, and S1 may be related to the second LTM reporting configuration. The SP field may be set to a value indicating SpCellInclusion. At operation 604, the UE 610 may determine an SP field value for indicating SpCellInclusion, and may apply a reporting configuration S0 including SpCell measurements. Alternatively, the UE 610 may apply reporting configuration S0 without SpCell measurements (e.g., if the SP field is included). At operation 605, the UE 610 may send an L1 measurement report to the source cell 620 according to reporting configurations S1 and S2, including SpCell measurements for S0. As an example, there may be a field (e.g., an SP field or any field providing functionality) in a downlink control message that changes an RRC configuration value or an interpretation of an RRC configuration value of at least one parameter related to SpCell inclusion in a reporting configuration.

[0082] In various example embodiments, for SP LTM CSI reporting on PUCCH, MAC CE signaling of SP LTM CSI reporting on PUCCH (i.e., SP LTM CSI reporting activation / deactivation MAC CE on PUCCH) may be used to update the reporting configuration of the activated SP LTM CSI reporting configuration. As an example, a field in the MAC CE may be used to update the SpCellInclusion configuration of one or more activated SP reporting configurations, such as Figure 4. In some example embodiments, the SP field (or any field that controls the inclusion of SpCell measurements in one or more reporting configurations) may be referred to as a configuration-included field. The configuration-included field may control the inclusion of SpCell reports for one or more reporting configurations activated by the same message that includes the configuration-included field. In the RRC configuration, the configuration of the SP report may be configured with SpCellInclusion. The UE may be expected to report current SpCell measurements in each report associated with the reporting configuration; however, the SpCellInclusion may be changed (e.g., removed or caused not to apply the configuration by the UE) with the MAC CE activation of the SP report. Therefore, it may not be expected that the UE 610 reports current SpCell measurements in each report associated with the reporting configuration (for which the SpCell inclusion is configured to not be enabled or not "true"). In the RRC message, the configuration-included field may be configured to include SpCell measurements for one or more (or specific) reporting configurations.

[0083] like Figure 4 As shown, a field (e.g., a one-bit field) in the MAC CE can be used to switch the configuration of SpCellInclusion. If the value of the field (i.e., the SP field) is set to a first value (e.g., "1"), the RRC configuration of SpCellInclusion can be switched between configured and unconfigured. Otherwise, if the value of the field (i.e., the SP field) is set to a second value (e.g., "0"), the RRC configuration of SpCellInclution can remain the same.

[0084] In certain example embodiments, in the event that more than one SP reporting configuration is activated, this field may be interpreted as a common configuration for updating the SpCellInclusion configuration for multiple reporting configurations (e.g., being activated). In some example embodiments, a separate field (i.e., bit) may be used for each reporting configuration to independently update the SpCellInclusion configuration. In some example embodiments, there may be at least one field for controlling the activation / deactivation fields associated with each reporting configuration (e.g., S i field) associated with the SpCell contained.

[0085] In some example embodiments, the MAC CE may include a field including a corresponding SP field associated with the activation / deactivation field (e.g., Figure 4 The indication provided by the SP field may configure the SpCell inclusion for the associated reporting configuration.

[0086] In some exemplary embodiments, the RRC configuration may indicate whether the SpCell inclusion may be changed by a (further) downlink control message (eg, MAC CE or DCI).

[0087] In some example embodiments, a message providing control information (such as a MAC or DCI) may control the inclusion of SpCell measurements for a measurement report. If the field is set to a first value (e.g., "0") or a value indicating that SpCell inclusion is not configured, the UE may not report SpCell measurements in the measurement report. If the field is set to a second value (e.g., "0") or a value indicating that SpCell inclusion is configured, the UE may report SpCell measurements in the measurement report.

[0088] According to various example embodiments, if the SP field is set to a first value (e.g., "1"), all reporting configurations that are activated and have SpCell inclusion configured (e.g., by RRC) may include SpCell measurements in the report. Alternatively, if the SP field is set to a second value (e.g., "0"), all reporting configurations that are activated and have SpCell inclusion configured may not include SpCell measurements in the report. Furthermore, deactivation of a reporting configuration may reset any dynamically configured SpCell inclusion parameters.

[0089] In certain example embodiments, for SP LTM CSI reporting on PUSCH, a DCI (e.g., an existing DCI format for scheduling uplink or downlink transmission or a new CI format including one or more fields for activating / deactivating SP CSI reporting) that activates or deactivates SP LTM CSI reporting on PUSCH may be used to update the reporting configuration of the activated SP LTM CSI reporting configuration. For example, a field (e.g., a one-bit field) in the DCI may be used to switch the RRC configuration of SpCellInclusion.

[0090] In some example embodiments, for aperiodic CSI reporting on PUSCH, a DCI that enables aperiodic LTM CSI reporting on PUSCH (e.g., a DCI format for enabling aperiodic CSI reporting triggering state) may be used to update the reporting configuration of the enabled aperiodic LTM CSI reporting configuration. For example, a field in the DCI (e.g., a one-bit field) may be used to switch / modify / change the RRC configuration of SpCellInclusion. A DCI format that provides selection / update of resource configuration and / or update of reporting configuration may or may not schedule any transmission.

[0091] Some exemplary embodiments may not include SpCell information to be reported. For example, at operation 606, the source cell 620 may send a MAC CE for reporting configuration on the PUCCH for SP activation to the UE 610, which may include S0 for LTM reporting configuration 1 and S1 for LTM reporting configuration 2. The SP field may be set to a value indicating that no SpCell is included. At operation 607, the UE 610 may determine the SP field value for indicating that no SpCell is included, and may apply reporting configurations S0 and S1 without including SpCell measurements. At operation 608, the UE 610 may send a (L1) measurement report to the source cell 620 according to reporting configurations S1 and S2 without including SpCell measurements.

[0092] In some example embodiments, the fields included in the configuration (in the control message) may refer to control information included in the control message (provided by the network). The control configuration includes SpCell information in a measurement report for one or more reporting configurations (e.g., includes SpCell measurement results).

[0093] In various example embodiments, a dependency between a serving cell SP report on the PUCCH and an LTM SP report on the PUCCH may be captured. Similarly, the dependency may apply to a serving cell (SP) report on the PUSCH and an LTM (SP) report on the PUSCH. For example, activation of at least one SP LTM CSI reporting configuration on the PUCCH may trigger deactivation of at least one or all serving cell SP CSI reporting configurations of the serving cell (e.g., on the same BWP), where the SP reporting configuration is associated with reporting of reference signals configured for LTM candidate cell measurements. Similarly, deactivation of some or all (e.g., if at least one is activated) SP LTM CSI reporting configurations on the PUCCH may trigger activation of at least one or all previously configured legacy SP reporting configurations of the serving cell (e.g., on the same BWP), where the SP reporting configuration is associated with reporting of reference signals configured for LTM candidate cell measurements (i.e., LTM SP reports on the PUCCH).

[0094] Figure 7 An example of a signaling diagram 700 for LTM / legacy dependency is shown. According to certain exemplary embodiments, UE 710 may be similar to UE 1020, and source cell 720, CU 730, and target cell 740 may be similar to NE 1010, such as Fig.10 as shown in .

[0095] At operation 701, the CU 730 may send an RRC reconfiguration message to the UE 710, which may indicate an LTM reporting configuration for an SP on a PUCCH on an LTM resource configuration and / or a serving cell report for an SP on a PUCCH on a serving cell resource configuration.

[0096] At operation 702 , the UE 710 may transmit an RRC reconfiguration complete message to the CU 730 .

[0097] At operation 703 , the source cell 720 may transmit, to the UE 710 , SP activation on MAC CEPUCCH for reporting configuration of serving cell reporting.

[0098] At operation 704, the UE 710 may send an L1 measurement report to the source cell 720 according to the serving cell report.

[0099] At operation 705 , the source cell 720 may transmit SP activation on MAC CEPUCCH for the reporting configuration of LTM reporting configuration 1 to the UE 710 .

[0100] At operation 706, the UE 710 may determine that the SP on the PUCCH is activated for the reporting configuration for the RS configuration for the LTM L1 measurement. For example, the UE 710 may determine to deactivate / suspend the serving cell reporting configuration 1.

[0101] In some example embodiments, activation of at least one SP reporting configuration on the PUCCH may trigger suspension of at least one or all serving cell SP CSI reporting configurations of the serving cell (e.g., on the same BWP), where the SP reporting configuration is associated with reporting a reference signal configured for LTM candidate cell measurements. The suspension may cause the UE to maintain the previous activation but suspend reporting (and measurements associated with the reporting). The network may configure whether serving cell SP CSI reporting should be deactivated / suspended. In various example embodiments, the dependency between LTM and serving cell CSI reporting may be configured by the network.

[0102] In various example embodiments, if activation of at least one SP LTM CSI report causes UE 710 to activate more than a maximum number of SP reporting configurations (e.g., the maximum number of simultaneously active SP reporting configurations or the maximum number of simultaneous CSI reports per BWP / CC), UE 710 may determine to deactivate the serving cell SP reporting configurations on the PUCCH of the serving cell, starting with the highest configuration ID until the maximum number is reached.

[0103] In certain example embodiments, SP reporting activation for LTM may cause the UE to deactivate serving cell SP CSI reporting.

[0104] In certain example embodiments, when signaling of SP reporting on PUCCH for LTM is transmitted in a MAC CE (i.e., a field or header in the MAC CE / DCI indicates whether activation / deactivation of one or more SP reporting configurations applies to the LTM configuration or the serving cell configuration), in the case where the activation indication is for LTM, the UE 710 may interpret one or more fields associated with SP reporting on PUCCH configuration for LTM, and the UE 710 may assume that the serving cell SP configuration is deactivated (until activated again) or suspended (until LTM SP reporting is deactivated). Otherwise, in the case where the field indicates for the serving cell, the UE 710 may assume that the serving cell SP CSI reporting configuration is activated, indicated by one or more other fields, and deactivate all LTM SPs on the PUCCH configuration.

[0105] At operation 707 , the UE 710 may send an L1 measurement report to the source cell 720 according to the LTM report configuration 1 .

[0136] As shown in 1012 and 1022, at least one memory may be provided in one or more devices. The memory may be fixed or removable. The memory may include computer program instructions or computer codes contained therein. The memories 1012 and 1022 may be any suitable storage device independently, such as a non-transient computer readable medium. The term "non-transient" as used herein may correspond to the limitations of the medium itself (i.e., tangible, non-signal), rather than limitations on data storage persistence (e.g., random access memory (RAM) versus read-only memory (ROM)). A hard disk drive (HDD), random access memory (RAM), flash memory or other suitable memory may be used. The memory may be combined on a single integrated circuit as a processor, or may be separated from one or more processors. In addition, the computer program instructions stored in the memory and that may be processed by the processor may be any suitable form of computer program code, such as a compiled or interpreted computer program written in any suitable programming language.

Transceivers 1013 and 1023 may be transmitters, receivers, both transmitters and receivers, or units or devices that may be configured for both transmission and reception.

[0139] The memory and the computer program instructions may be configured to, together with a processor for a specific device, cause a hardware device such as a UE to perform the above-described process (ie, Figure 5-9 ). Thus, in some example embodiments, a non-transitory computer-readable medium may be encoded with computer instructions that, when executed in hardware, perform a process such as one of the processes described herein. Alternatively, some example embodiments may be performed entirely in hardware.

[0140] In certain example embodiments, the apparatus may include a Figure 5-9 As used in this application, the term "circuit" may refer to one or more or all of the following: (a) a hardware-only circuit implementation (such as an implementation in analog and / or digital circuits only), (b) a combination of hardware circuits and software, such as (as applicable): (i) a combination of analog and / or digital hardware circuits and software / firmware, and (ii) a hardware processor (including a digital signal processor) with software, software, and any portion of memory that work together to enable a device such as a mobile phone or server to perform various functions, and (c) a hardware circuit and / or processor, such as a microprocessor or a portion of a microprocessor, which requires software (e.g., firmware) to operate, but when software is not required to operate, the software may not be present. This definition of circuit applies to all uses of the term in this application, including in any claims. As a further example, as used in this application, the term circuit also covers an implementation of a hardware circuit or processor (or multiple processors) or a portion of a hardware circuit or processor and its (or their) accompanying software and / or firmware. The term circuitry also covers, for example and if applicable to a particular claim element, a baseband integrated circuit or a processor integrated circuit for a mobile device or a similar integrated circuit in a server, cellular network device, or other computing or networking device.

[0141] Fig.11 Examples of 5G network and system architectures according to certain exemplary embodiments are shown. Multiple network functions are shown, which can be implemented as software operating as part of a network device or dedicated hardware, as a network device itself or dedicated hardware, or as virtual functions operating as a network device or dedicated hardware. Fig.11 The NE and UE shown in the figure may be similar to NE 1010 and UE 1020, respectively. The user plane function (UPF) may provide services such as intra-RAT and inter-RAT mobility, routing and forwarding of data packets, inspection of packets, user plane quality of service (QoS) processing, buffering of downlink packets and / or triggering of downlink data notifications. The application function (AF) may primarily interface with the core network to facilitate application use of service routing and interact with the policy framework.
