Description

Technical Field

[0001] Some example embodiments may generally relate to mobile or wireless communication systems, such as 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE), 5th Generation (5G) Radio Access Technology (RAT), New Radio (NR) Access Technology, 6th Generation (6G) and / or other communication systems. For example, some example embodiments may relate to systems and / or methods for supporting periodic and semi-persistent (SP) reporting on the Physical Uplink Control Channel (PUCCH). Background Technology

[0002] In 3GPP, Layer 1 (L1) / Layer 2 (L2) triggered mobility (LTM) is a cell handover procedure in which the UE's serving cell (e.g., primary cell (PCell) or primary / secondary cell (PSCell)) can be switched by the network by sending an LTM cell handover command. The LTM handover command can be delivered via Media Access Control (MAC) signaling using a MAC Control Element (CE). Therefore, cell handovers can currently be performed without using Radio Resource Control (RRC) signaling as an L3-based handover. LTM cell handover decisions can be based on measurements (e.g., L1 measurements) that can be performed and reported by the UE (e.g., L1 measurement reports). Measurements and reporting can be based on an LTM candidate cell configuration provided by the network for one or more LTM candidate cells. LTM candidate cells can include the UE's neighboring cells and / or any currently serving cell (e.g., SCell). Improvements to LTM procedures and technologies are expected. Summary of the Invention

[0025] It is readily understood that, as generally described and illustrated in the accompanying drawings, components of certain example embodiments can be arranged and designed in a variety of different configurations. Therefore, 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 rather represents selected example embodiments.

[0026] Prior to cell handover, the network may optionally activate one or more Transport Configuration Indicator (TCI) states for one or more candidate cells. After a candidate cell TCI state is activated, the UE can track the timing of the activated TCI state. The UE may also perform early uplink (UL) synchronization prior to cell handover (if requested by the network).

[0027] Figure 1 An example LTM procedure is described. At step 1, the UE can send a message to the gNB (i.e., the base station). MeasurementReport The gNB can determine the LTM configuration and initiate candidate cell preparation. In step 2, the gNB can send a message to the UE. RRCReconfiguration The message includes the LTM candidate cell configuration of at least one candidate cell. In step 3, the UE can store the LTM candidate cell configuration and send it to the gNB. RRCReconfigurationComplete information.

[0028] At step 4a, the UE may perform DL synchronization with the candidate cell before receiving the cell handover command. At step 4b, the UE may perform early timing advance (TA) acquisition of the candidate cell requested by the network before receiving the cell handover command. For example, this may be performed via 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. To minimize data interruption to the source cell due to CFRA to the candidate cell, the UE may not receive a random access response (RAR) to acquire the TA value. The TA value of the candidate cell may be indicated in the cell handover command. The UE may not maintain a TA timer for the candidate cell, but may rely on the network implementation to ensure TA validity.

[0029] At step 5, the UE can perform L1 measurements on the configured candidate cells and send a low-layer measurement report to the gNB. At step 2, measurements, such as L1 measurements, can be performed according to the configuration in the RRC reconfiguration. At step 6, the gNB can determine to perform a cell handover to the target cell and can send a MAC CE that triggers the cell handover by including the candidate configuration index of the target cell. The UE can then handover to the target cell and apply the configuration indicated by the candidate configuration index.

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

[0031] At step 8, the UE can complete the LTM cell handover process (e.g., by sending a message to the target cell). RRCReconfigurationComplete (Message). If the UE has already performed the RA procedure in step 7, the UE can consider the LTM execution to have been successfully completed when the random access procedure is successfully completed. For LTM without a random access channel (RACH), the UE can consider the LTM execution to have been successfully completed when it determines that the network has successfully received its first UL data. The UE can determine the successful reception of its first UL data by receiving the PDCCH of the UE's Cell Radio Network Temporary Identifier (C-RNTI) in the addressing target cell, which can schedule new transmissions after the first UL data. It should be noted that for subsequent LTM cell handovers, steps 4-8 can be performed multiple times using the LTM candidate cell configuration provided in step 2.

[0032] In LTM, the UE can perform a MAC reset. Using RRC signaling, the network can control whether the UE performs Radio Link Control (RLC) re-establishment and Packet Data Convergence Protocol (PDCP) data recovery during cell handover. The PDCP data recovery process can be applied to RLC Acknowledgment Mode (AM) Data Radio Bearer (DRB) for inter-Distributed Cell (DU) LTM cell handover.

[0033] For LTM, information about measurement resources (e.g., Synchronization Signal Block (SSB) or CSI-RS) from LTM candidate cells can be provided to the UE so that the UE can perform measurements. The UE can also be configured with an L1 measurement reporting configuration, in which the UE can report measurements. For LTM, periodic SP reporting on the PUCCH, SP reporting on the Physical Uplink Shared Channel (PUSCH), and non-periodic reporting on the PUSCH can be supported.

[0034] Each reporting setting (e.g., LTM-CSI-ReportConfig This can be associated with the LTM resource configuration used for channel measurements, and can accordingly include... ltm-ReportConfigType The parameters for the provided time-domain behavior (i.e., periodicity, SP reporting on PUCCH, SP reporting on PUSCH, and non-periodic reporting on PUSCH) are provided by... noOfReportedCell and noOfReportedRS-PerCell The corresponding number of candidate cells and the number of reference signals for each candidate cell are provided, including L1 measurements associated with the current special cell (SpCell) (if...). spCellInclusion (Configured).

[0035] LTM-CSI-ReportConfig The temporal behavior can be determined by higher-level parameters. ltm-ReportConfigType The indicator can be set to 'aperiodic', 'semiPersistentOnPUCCH', 'semiPersistentOnPUSCH', or 'periodic'. For 'periodic' and 'semiPersistentOnPUCCH' / 'semiPersistentOnPUSCH' Channel State Information (CSI) reporting, the configured period and slot offset can be applied to the digital technology on which the CSI report is configured to be transmitted in the UL bandwidth portion (BWP).

[0036] A set of LTM CSI reporting configurations can be configured, which contains one or more CSI reporting configurations (e.g., LTM-CSI- ReportConfigThis configuration is separate from the traditional CSI reporting configuration (i.e., used for serving cell beam management and CSI acquisition). Each CSI reporting configuration (i.e., LTM and traditional) can have its own identifier (ID) space (e.g., report configuration identifier), from 0 to a predetermined number. For example, traditional CSI reporting could refer to CSI reporting (serving cell CSI reporting).

[0037] The UE can be configured with one or more CSI reporting configurations, where each reporting configuration can include an LTM CSI resource configuration containing information about resources to be used for channel measurements (e.g., L1-Reference Received Power (RSRP) measurements). The LTM resource configuration can contain SSBs from one or more candidate cells. For each reporting configuration, the UE can be configured to report M beams (i.e., each LTM CSI resource setting) from each of the L configured candidate cells. LTM-CSI-ResourceConfig ) can contain LTM-CSI-SSB-ResourceSet The configuration of this resource set includes a list of Z≥1 Synchronization Signal (SS) / Physical Broadcast Channel (PBCH) block indices (by... ltm-CSI-SSB-ResourceList (Given) and Z LTM-CandidateId The list (by) ltm-CandidateIDList (Given), its reference is the candidate cell associated with the SS / PBCH block index). For each candidate cell, the UE can, according to ssb-Periodicity and ssb- PositionsInBurst The temporal behavior of SS / PBCH block resources is determined. The frequency domain behavior of SS / PBCH block resources can be determined using higher-level parameters. subCarrierSpacing , ssbFrequency To determine.

[0038] If the UE is configured with LTM-CSI-ReportConfig And if the UE is configured with spCellInclusion Then the UE can report in a single reporting instance. noOfReportedRS-PerCell A different SSBRI For the current SpCell, and noOfReportedCells -1 candidate cells from the candidate cells. Otherwise, the UE can report in a single reporting instance. noOfReportedRS-PerCell Two different SS / PBCH block resource indicators (SSBRI) are used for noOfReportedCell For each of the candidate cells, SSBRI k ( k ≥0) corresponds to the corresponding LTM- CSI-SSB-ResourceSet Related ltm-CSI-SSB-ResourceList The configuration of the ( k +1) entry.

[0039] If spCellInclusion is configured, then the cells associated with the current SpCell... ltm-CSI-SSB- ResourceList The SSB resources in the data can be the associated candidate cells (in ltm-CandidateIdList The entries whose Physical Cell Identifier (PCI) and Frequency Information (e.g., given by the SSB frequency) are equal to the PCI and Frequency Information (e.g., given by the SSB frequency) of the current SpCell.

[0040] For Rel-18 gNB scheduling L1 measurement reporting, LTM can support reporting as UCI; similarly, SP reporting can be supported on the PUSCH, and aperiodic reporting can also be supported on the PUSCH. A single report instance can include reports for serving cells and candidate cells within and / or between frequencies.

[0041] For beam selection in SSB-based L1-RSRP measurement reporting, beam selection can be performed in L cells out of the configured (or, if introduced, active) cells (i.e., each of the L cells has M beams). M×L beams can be reported in a single reporting instance. The maximum values ​​of M and L can be based on UE capabilities, and at least M×L=4 can be supported as a UE capability. The values ​​of M and L can be configured in the UE's reporting configuration. Furthermore, for L1 measurement reporting scheduled by gNB, periodicity on PUCCH and SP reporting can be supported. For beam selection in SSB-based L1-RSRP measurement reporting, the inclusion of the current SpCell in the L1 measurement report is configurable.

[0042] For beam selection in L1-RSRP measurement reporting based on SSB, the candidate values ​​for M and L in the RRC configuration can be M=1, 2, 3, 4, and L=1, 2, 3, 4. The UE capability can determine M. The maximum value of L and the combination of M and L.

[0043] 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] dBm, with a step size of 1 dB. 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 based on a reference L1-RSRP value, with a step size of 2 dB.

[0044] Each L1-RSRP report may include the SSBRIs from the configured candidate cells. The bit size of the SSBRI can be... ,in This refers to the number of SSBs configured in the corresponding resource set for this report. The following format can be used for reporting:

[0048] IE LTM-CSI-ResourceConfig The following fields may also be included in the description:

[0049] For SP reporting on PUCCH, the PUCCH resource used to send CSI reports can be accessed via... reportConfigType The SP reporting on the PUCCH can be activated by an activation command, which selects one of the SP reporting settings for the UE to use on the PUCCH. When the UE transmits a PUCCH with Hybrid Automatic Repeat Request (HARQ) Acknowledgment (ACK) information in slot n corresponding to the Physical Data Sharing Channel (PDSCH) carrying the activation command, the indicated SP reporting settings can be configured from the slot. The first time slot thereafter is applied, where µ is the subcarrier spacing (SCS) configuration for PUCCH.

[0050] When the UE transmits a PUCCH with HARQ-ACK information in slot n corresponding to the PDSCH carrying the activation command, the UE can perform a switch from slot n. n + 3Nslotsubframe, SPCSI reporting on the PUCCH begins in the first time slot following μ, where µ is the SCS configuration for the PUCCH. The activation command can contain one or more reporting settings, where the associated CSI resource settings are configured.

[0051] Figure 2The illustration shows an example of SP CSI reporting activation / deactivation of MAC CE on a PUCCH. SP CSI reporting activation / deactivation of MAC CE on a PUCCH can be identified by a MAC subheader with a Logical Channel ID (LCID) value of 25. It can be a fixed 16-bit size and include several fields, such as the Serving Cell ID. This field indicates the identifier of the serving cell to which the MAC CE applies; the field length can be 5 bits. The MAC subheader can also include a BWP ID field, which indicates the UL BWP to which the MAC CE applies, as a code point in the DCI Bandwidth Part Indicator field; the BWP ID field length can be 2 bits. The MAC subheader can also include S... i This field indicates csi-ReportConfigToAddModList The activation / deactivation status of the internal SPCSI reporting configuration.

If the type in the indicated BWP is set to... semiPersistentOnPUCCH If the number of report configurations in the list is less than i+1, then the MAC entity can ignore S. i Field. S i The field can be set to 1 to indicate that the corresponding SP CSI report configuration can be activated. i The field can be set to 0 to indicate that the corresponding SP CSI report configuration i should be deactivated. The MAC subheading may also include a reserved bit R that is set to 0.

[0052] The reporting configuration for LTM reports can be provided in the RRC configuration (e.g., including the configuration included in SpCell). SpCellInclusion This configuration indicates whether the current SpCell measurement should be included in the report; and the associated resource configuration, which may include resource signaling information for one or more candidate cells to be considered for measurement and reporting. For dynamically activated / triggered LTM reporting (e.g., SP reporting on PUCCH (up to 4), SP reporting on PUSCH, aperiodic reporting), a limited number of RRC reporting configurations may exist. As the UE moves, the RRC reporting configuration may need to be updated (e.g., the candidate cells to be considered for measurement and reporting). Due to the limited number of RRC reporting configurations, any update may require RRC reconfiguration, which is a slow process.

[0053] Some of the example embodiments described herein may have various benefits and / or advantages to overcome the aforementioned disadvantages. For example, some example embodiments may provide a solution for the UE to dynamically update the resource configuration for CSI reporting configuration used in LTM. Therefore, some example embodiments discussed below are intended to improve computer-related technologies.

[0054] For one or more (e.g., LTM) CSI reporting configurations, certain example embodiments may enable dynamic updates of resource configurations, including configurations containing reference signal resources from one or more candidate cells considered for measurement and reporting. 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, updated resource configurations for reporting configurations may be provided for serving cell CSI reporting (e.g., for beam management). Various example embodiments may be used 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] Figure 3 An example of signaling diagram 300 for supporting periodicity and SP reporting on PUCCH is illustrated. According to certain example embodiments, such as... Figure 8 As shown, UE 320 can be similar to UE 820, and source cell 330, CU 340 and target cell 350 can be similar to NE 810.

[0056] At operation 301, UE 320 can send L3 measurements to CU 340.

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

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

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

[0060] At operation 305, source cell 330 can send a MAC CE to UE 320 to activate the LTM SP first report configuration on PUCCH, indicating that the resource configuration has not changed.

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

[0062] At operation 307, UE 320 can send L1 measurement reports to source cell 330. For example, UE 320 can send selected measurements of source cell 330, CU 340, and target cell 350.

[0063] At operation 308, source cell 330 may send a MAC CE to UE 320 to activate SP reporting configuration 1 on PUCCH, which indicates that the resource configuration has changed and that source cell 330 or target cell 350 should be selected.

[0064] In some example embodiments, signaling for activating, updating, and / or triggering dynamic LTM CSI reporting can be used to dynamically update the resource configuration of one or more reports that are being activated / triggered. This signaling can also be used to deactivate at least one (or all) reporting configurations. In various example embodiments, CSI reporting 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 Signal-to-Interference-plus-Noise Ratio (SINR), or... CapabilityIndex .

[0065] In some example embodiments, when signaling for SP reporting on the PUCCH for LTM is communicated in the MAC CE (i.e., a field in the MAC CE indicates whether activation / deactivation of one or more SP reporting configurations applies to the LTM configuration or the serving cell configuration), the MAC CE (i.e., the SP LTM CSI reporting activation / deactivation MAC CE on the PUCCH) can be used to dynamically update the resource configuration (e.g., to take into account the reference signal resources used for measurement and reporting) of one or more SP reporting configurations that are currently active.

[0066] In various example embodiments, resources from one or more LTM candidate cells can be removed (configured to be disregarded) from the resource configuration set of the RRC configuration associated with the active SP CSI reporting for measurement and reporting. For example, for an SP CSI reporting configuration on a PUCCH, the associated resource configuration in the RRC configuration may include [SSB 1 of cell 1, SSB 2 of cell 1, SSB 1 of cell 2, SSB 2 of cell 3, SSB 3 of cell 3, SSB 4 of cell 3]. Using the MAC CE SPLTM CSI activation / deactivation command, the resource configuration can 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. Therefore, UE 320 can consider only the indicated resources of cell 2 and cell 3 for measurement and reporting.

[0067] Figure 3 The diagram illustrates where a new bit field C can be added. i Examples (C0 to C7). Each bit field can indicate the configuration of the candidate cell (e.g., C...). n This represents the configuration of candidate cell 'n' (LTM candidate cell ID=n)). Alternatively, candidate cell IDs can be mapped to C in the order of LTM candidate IDs (e.g., ascending order). n (For example, starting with C0) fields. In one example, if any C i If the value of the bit field (i=0 to 7) is set to the first value (e.g., '0'), then the resources of that candidate cell may not be considered for measurement and reporting, regardless of whether any resources exist in the resource configuration. In one example, if any C i If the value of a bit field (e.g., i = 0 to 7) is set to a first value (e.g., '0'), then the resources of that candidate cell may not be considered for measurement and reporting (i.e., the resources corresponding to the candidate cell can be configured by RRC, but using (multiple) C... i (Fields to activate). Otherwise, if any C i If the value of the field (i=0 to 7) is set to the second value (e.g., '1'), the resource configuration associated with the candidate cell provided in the RRC configuration may remain unchanged. Alternatively, if any C i If the value of the field (i=0 to 7) is set to the second value (e.g., '1'), and the resource has a corresponding RRC configuration, then the resource configuration associated with the candidate cell provided in the RRC configuration can be considered for measurement and reporting. Therefore, if C i The value of field (i=0 to 7) is set to '1', and candidate cell C iIf the resources are included in the resource configuration, then these resources can be considered for measurement and reporting, while if candidate cell C i If resources are not included in the resource configuration, then those resources used for measurement and reporting cannot be considered. In some alternative example embodiments, each C i Fields can correspond to configured resource settings (e.g., RRC configuration). For example, C i The first C field (such as C0) can correspond to the first RRC configuration of the resource, while C i The second C field (such as C1) of the field may correspond to the second RRC configuration of the resource. The first resource configuration and the second resource configuration may include one or more DL RSs (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 a given SSB of source cell 330, CU 340 and target cell 350 for measurement and / or reporting.

[0069] At operation 310, UE 320 can send L1 measurement reports to source cell 330, including selected measurements for source cell 330 or target cell 350.

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

[0071] Some example implementations may include a field that includes an activation / deactivation field ( Figure 4 A set of corresponding fields C (S0...S1) in the database. i Fields. By C i The field provides indications for configuring candidate cell configurations (e.g., for resource configuration) for the associated reporting configuration.

[0072] In various example embodiments, such as Figure 5 As shown, a separate set of bit fields (one per reporting configuration) can be used for each reported configuration to update resource configurations independently. For example, C i This field can be used to indicate resource configuration / candidate cell C i Should related measurements (always) be included in the report? For example, if C iIf the field value is set to '1', the UE 320 may need to report the resource configuration / candidate cell C in each report associated with the currently active reporting configuration. i At least one associated measurement. As an example, for each reporting configuration that is provided or updated and activated (e.g., Figure 5 S in i The field may include a bit field, which includes one or more resource configuration activation / deactivation fields (e.g., including C). i The field's octet (bytes). No indication was given of the reporting configuration to be updated (e.g., S). i Resource configuration fields (e.g., including C) where the field is set to the first value '0'. i The octet (e.g., octet) may not exist. In some examples, resource configuration fields (e.g., octets) may be updated according to the S specified in the instructions. i The fields are listed in order (e.g., bits are set to the second value '1'). Alternatively, resource configuration fields can be fixed.

[0073] As another example, in addition to candidate cells, additional fields can be used to indicate whether resources given in the resource configuration (e.g., DL RS, SSB, or CSI-RS indexes) should be considered for measurement and reporting.

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

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