Description

Technical Field

[0001] This disclosure relates to the field of communication technology, and in particular to a measurement report reporting method, apparatus and storage medium. Background Technology

[0002] To further reduce handover latency, signaling overhead, and downtime, 3GPP introduced the LTM (L1 / L2 Triggered Mobility) mechanism in Release 18. The UE (User Equipment) performs Layer 1 measurements based on the candidate cell configuration information configured by the network and reports the results. The network determines whether cell handover needs to be triggered based on the reported Layer 1 measurement results and instructs the UE to perform the cell handover process via Layer 2 signaling (Media Access Control Unit MAC CE).

[0003] Compared to the handover process based on the Layer 3 measurement reporting mechanism, the LTM process does not support event-triggered measurement reporting, and periodic reporting would cause unnecessary signaling overhead. In order to further improve the performance of the LTM mechanism and reduce the signaling overhead of the Layer 1 L1 measurement reporting mechanism, 3GPP will conduct research on event-triggered L1 measurement and reporting mechanisms in Release 19 to improve the performance of LTM. Summary of the Invention

[0050] The technical solutions of this disclosure will be further described in detail below with reference to the accompanying drawings and embodiments.

[0051] In related technologies, the UE reports L1 measurement results of LTM candidate cells via UCI (Uplink Control Information). The network side configures the number of candidate cells that the UE can report and the number of reference signal measurement results that can be reported for each candidate cell.

[0052] According to the network configuration, each L1 measurement report submitted by the UE contains a fixed number of L1 measurement results. Even if the signal quality of some candidate cells is not good enough, the UE still needs to submit the relevant measurement results according to the network configuration, which will result in a waste of uplink resources.

[0053] After introducing an event-triggered L1 measurement reporting mechanism, using the aforementioned L1 measurement reporting methods, such as the existing UCI-based method for reporting LTM candidate cell L1 measurement results, the UE still needs to report a fixed number of candidate cell measurement results. This leads to problems such as a shortage of uplink UCI resources and the need for a fixed format for the reported content. Furthermore, based on the measurement results reported by the UE, the network cannot directly and quickly determine which candidate cells meet the event triggering conditions, thus hindering timely handover decisions and impacting LTM performance. Moreover, reporting measurement results that do not meet the triggering conditions also wastes uplink resources and incurs unnecessary overhead.

[0054] To address the aforementioned issues, this disclosure proposes a measurement report submission method, apparatus, and storage medium, enabling more flexible L1 measurement reporting, resolving the resource shortage problem of UCI-based reporting, saving uplink UCI resources, and achieving flexible reporting.

[0055] Flowcharts of some embodiments of the user equipment measurement report reporting method disclosed herein are as follows: Figure 1 As shown.

[0056] In step S11, the user equipment performs an L1 measurement.

[0057] In step S12, if the L1 measurement reporting conditions are met, an L1 measurement report is sent via MAC CE. The L1 measurement report has the ability to carry the L1 measurement results of multiple candidate cells and can flexibly carry the L1 measurement results of at least one candidate cell according to actual needs.

[0058] In some embodiments, the L1 measurement report carries the L1 measurement results of at least one candidate cell that meets the L1 measurement reporting conditions, thereby facilitating the network side to obtain the measurement result information of the candidate cells that meet the L1 measurement reporting conditions. In some embodiments, the L1 measurement report may carry the L1 measurement results of candidate cells that do not meet the L1 measurement reporting conditions, thereby facilitating the network side to understand the status of the candidate cells and update or modify the candidate cells in a timely manner.

[0059] In some embodiments, the number of candidate cells that meet the L1 measurement reporting conditions can be greater than 1. The L1 measurement report can carry the L1 measurement results of each candidate cell that meets the L1 measurement reporting conditions, thereby improving the flexibility and reliability of the network side in making LTM handover judgments and managing candidate beams, and improving network performance and user experience.

[0060] In some embodiments, an upper limit can be set on the number of candidate beams reported by a single candidate cell, that is, the upper limit of beams involved in a single MACCE for a single candidate cell.

[0061] If the number of candidate beams in a candidate cell that meet the L1 measurement reporting conditions is greater than or equal to the upper limit N of the number of candidate beams reported by a single candidate cell. max Then, N is selected from the candidate beams that meet the L1 measurement reporting conditions. max The measurement results of each candidate beam are reported, thereby ensuring that the measurement results of candidate beams that meet the L1 measurement reporting conditions are fully reported while limiting resource consumption. In some embodiments, candidate beams can be selected randomly; in other embodiments, candidate beams can be selected in descending order of measurement results.

[0062] If the number of candidate beams in a candidate cell that meet the L1 measurement reporting conditions is less than the upper limit N of the number of candidate beams reported by a single candidate cell. max Then, the measurement results of all candidate beams that meet the L1 measurement reporting conditions can be reported, so that the measurement results of candidate beams that meet the L1 measurement reporting conditions are fully reported.

[0063] In some embodiments, if the number of candidate beams in a candidate cell that meet the L1 measurement reporting conditions is less than the upper limit N of the number of candidate beams reported by a single candidate cell... max Then, the L1 measurement results corresponding to each candidate beam that meets the L1 measurement reporting conditions can be reported, as well as the L1 measurement results corresponding to at least one beam that does not meet the L1 measurement reporting conditions or the L1 measurement results corresponding to at least one beam that is not configured for event-triggered reporting. In some embodiments, if the number of candidate beams that meet the L1 measurement reporting conditions in a candidate cell is less than the upper limit N of the number of candidate beams reported by a single candidate cell... max This allows for the reporting of L1 measurement results for each candidate beam that meets the L1 measurement reporting conditions, the L1 measurement results for at least one beam that does not meet the L1 measurement reporting conditions, and the L1 measurement results for at least one beam that is not configured for event-triggered reporting. This method fully utilizes the space in the MAC CE that can carry measurement results, providing more information to the network side and facilitating network-side decision-making.

[0064] Based on the method in the embodiments described above, event-triggered L1 measurement reports are carried through MAC CEs, avoiding the occupation of uplink UCI resources. This solves the problem of UCI resource scarcity while avoiding restrictions on packets using UCI reporting, thus improving the flexibility of L1 measurement reporting. MAC CEs can carry measurement results from multiple candidate cells, thereby improving the flexibility and reliability of LTM handover judgment and candidate beam management on the network side, and enhancing network performance and user experience.

[0065] In some embodiments, the MAC CE can indicate and carry the measurement results of the candidate cell through multiple indication fields. The MAC CE may include at least one of the following:

[0066] The sixth indication field of a candidate beam for a candidate cell;

[0067] The seventh indication field indicates the L1 reference signal received power RSRP corresponding to the candidate beam indicated in the sixth indication field.

[0068] This method allows the transmission of candidate beam indication information and the measured RSRP, facilitating the network side to determine the measurement results and the corresponding reference signal.

[0069] In addition to the sixth and seventh indication fields, MAC CE can also use multiple indication fields to indicate and carry the measurement results of candidate cells.

[0070] For example, MAC CE includes at least one of the following:

[0071] The first indication field indicates the candidate cell corresponding to the L1 measurement result carried in the MAC CE;

[0072] For each candidate cell, a second indication field indicates whether the MAC CE carries the L1 measurement results of one or more beams of the corresponding candidate cell.

[0073] The MAC CE in the above embodiment facilitates the network side to identify candidate cells and candidate beams of candidate cells, and then reads the corresponding L1 measurement results, thereby improving the accuracy of network side information identification.

[0074] In some embodiments, the second indication fields corresponding to different candidate cells are spaced apart by at least one L1 measurement result corresponding to a candidate cell. The second indication fields and corresponding measurement results of different cells exist in the MAC CE structure in a continuous manner with the second indication fields corresponding to the same candidate cell and the sixth and seventh indication fields. For example, they are arranged in the order of the second indication field of candidate cell X → L1 measurement result corresponding to candidate cell X → second indication field of candidate cell Y → L1 measurement result corresponding to candidate cell Y... This helps the network side to continuously read information for a single candidate cell.

[0075] In some embodiments, the second indication field corresponding to each candidate cell occupies the same length, and the second indication fields are arranged in the order of the corresponding candidate cell identifiers, so that information of the same type is arranged continuously, for example, in the order of the second indication field of candidate cell X → the second indication field of candidate cell Y... → the L1 measurement result corresponding to candidate cell X → the L1 measurement result corresponding to candidate cell Y...

[0076] In some embodiments, the first indication field indicates the candidate cell corresponding to the L1 measurement result carried by the MAC CE through a bitmap. This method can improve the accuracy of the indication and improve processing efficiency.

[0077] In some embodiments, the second indication field indicates the candidate beam corresponding to the L1 measurement result carried by the MAC CE through a bitmap, thereby improving the accuracy of the indication and improving processing efficiency.

[0078] In some embodiments, the length of the first indication field is matched with the maximum number of candidate cell IDs that can be configured on the network side, such as the length being equal to the number of candidate cell IDs that can be configured on the network side, thereby improving the matching degree and reliability of the system.

[0079] In some embodiments, the length of the second indication field is matched with the upper limit of the number of candidate beams reported by a single candidate cell, thereby improving the matching degree between different fields of MAC CE and avoiding network-side leakage and over-identification of measurement information.

[0080] In the same MAC CE, the second indication fields corresponding to different candidate cells occupy the same length, and the second indication fields corresponding to different candidate cells are arranged in the order of the identifiers of their respective candidate cells, thereby facilitating the network side to identify the candidate cells corresponding to the second indication fields. In some embodiments, the order of the candidate cell identifiers can be a predetermined order value, such as arranging them in order from smallest to largest (or from largest to smallest); the order of the candidate cell identifiers can be configured by the network side.

[0081] For example, MAC CE includes at least one of the following:

[0082] A third indication field that indicates the number of candidate cells corresponding to the L1 measurement results carried in the MAC CE;

[0083] The fourth indication field indicates the identifier of the candidate cell corresponding to the L1 measurement results carried in the MAC CE.

[0084] This method allows the network side to easily determine the number of candidate cells corresponding to the MAC CE based on the third indication field, and further read the identifier of the candidate cells based on this number, avoiding the network side from missing or over-identifying the identifiers of candidate cells. This approach can reduce the bit length required to indicate candidate cells, making it easier to shorten the signaling length and reduce the signaling burden.

[0085] In some embodiments, at least one L1 measurement result corresponding to a candidate cell is spaced between the fourth indication fields corresponding to different candidate cells. The fourth indication fields and corresponding measurement results of different cells exist in the MAC CE structure in a continuous manner with the fourth indication fields and the sixth and seventh indication fields corresponding to the same candidate cell. For example, they are arranged in the order of the fourth indication field of candidate cell X → L1 measurement result corresponding to candidate cell X → fourth indication field of candidate cell Y → L1 measurement result corresponding to candidate cell Y... This helps the network side to continuously read information for a single candidate cell.

[0086] For example, MAC CE includes:

[0087] The fifth indication field indicates whether the L1 measurement results of one or more beams for each candidate cell are carried in the MAC CE.

[0088] In this way, the fifth indication field can carry both the candidate cell and the indication information of the candidate cell's beam. Based on this field, the network side can determine whether the MAC CE includes the L1 measurement results for each beam of each candidate cell, thereby improving the network side's reading efficiency.

[0089] In some embodiments, the length of the fifth indication field is matched with the upper limit of the number of supported candidate cells. The fifth indication field includes indications of the beams of a predetermined number (which may be the upper limit of the nominal number) of candidate cells. The indications are sorted in a predetermined order according to the identifiers of the corresponding candidate cells (e.g., arranged in order from smallest to largest or from smallest). The length of the fifth indication field corresponding to each candidate cell is the same. The network side can determine the correspondence between each bit in the fifth indication field and the candidate cells according to the sorting of the candidate cells, and then determine whether to carry the measurement results of one or more candidate beams of the candidate cells according to the information carried by each bit.

[0090] In some embodiments, the length of the fifth indication field matches the number of candidate cells configured on the network side. The length of the fifth indication field in the MAC CE can be flexibly adjusted through network-side configuration, which facilitates flexible control of the L1 measurement report length and reduces signaling burden. In this embodiment, the fifth indication field only indicates whether the MAC CE carries the L1 measurement results of one or more beams of the candidate cells configured on the network side. The indication is sorted according to the corresponding candidate cell identifiers in a predetermined order (e.g., from smallest to largest, or from smallest to largest). The length of the fifth indication field is the same for each candidate cell configured on the network side. The network side can determine the correspondence between each bit in the fifth indication field and the candidate cells configured on the network side based on the order of the candidate cells, and then determine whether to carry the measurement results of one or more candidate beams of the candidate cells based on the information carried by each bit.

[0091] In some embodiments, the measurement result carried in the MAC CE is obtained by measuring the SSB as a reference signal. In this case, the sixth indication field indicates the candidate beam of the candidate cell using the reference signal index value of the SSB-based synchronization signal and physical broadcast channel block included in the Layer 1 Layer 2 triggered mobility LTM CSI resource set for L1 measurement. The seventh indication field indicates the L1 RSRP corresponding to the SSB-based reference signal index value in the sixth indication field, thus facilitating accurate interpretation of the measurement results by the network side. The length occupied by the sixth indication field matches the number of SSB resources in the resource set configured by the network side.

[0092] In some embodiments, the measurement result carried in the MAC CE is obtained by measuring CSI-RS as a reference signal. The sixth indication field indicates the candidate beam of the candidate cell using the reference signal index value of the CSI-RS based on channel state information contained in the LTM CSI resource set used for L1 measurement. The seventh indication field indicates the L1 RSRP corresponding to the CSI-RS-based reference signal index value in the sixth indication field. This facilitates the network side in accurately determining the type of reference signal and interpreting the measurement results accurately. The length of the sixth indication field matches the number of CSI-RS resources configured in the resource set on the network side.

[0093] In the second and fifth indication fields mentioned above, for the same candidate cell, the number of candidate beams carrying measurement reports is the same as the number of the sixth and seventh indication fields. The sixth and seventh indication fields correspond one-to-one, and can be grouped together as one sixth and one seventh indication field. The MAC CE carries a combination of one or more sixth and seventh indication fields, which helps to improve the convenience and accuracy of network-side reading.

[0094] In some embodiments, the MAC CE further includes an eighth indication field indicating the type of reference signal on which the L1 measurement report is based. When the reference signal is an SSB, the sixth indication field indicates the SSB-based reference signal index value included in the LTM CSI resource set for L1 measurement of the candidate beam, and the seventh indication field indicates the L1 RSRP corresponding to the SSB-based reference signal index value in the sixth indication field; when the reference signal is a CSI-RS, the sixth indication field indicates the CSI-RS-based reference signal index value included in the LTM CSI resource set for L1 measurement of the candidate beam, and the seventh indication field indicates the L1 RSRP corresponding to the CSI-RS-based reference signal index value in the sixth indication field.

[0095] In this way, a single message body can carry measurement information based on both SSB reference signals and CSI-RS reference signals, and is identified by the fifth indication field, which facilitates network-side identification and improves the flexibility and compatibility of the UE.

[0096] In some embodiments, the MAC CE also includes reserved bits for byte alignment within the MAC CE.

[0097] In some embodiments, corresponding to the MAC CE carrying measurement results of at least one candidate cell as shown above, an exemplary schematic diagram of the MAC CE in the measurement report reporting method of this disclosure is shown below. Figure 2A-2B As shown in 3A-3C, when the reporting conditions for L1 measurement reports are met, the UE reports L1 measurement reports for LTM using the following variable-length MAC CE format, which includes at least one of the L1 measurement results based on SSB or CSI-RS for one or more LTM candidate cells.

[0098] Option 1-1, such as Figure 2A-2B As shown, a MAC CE format is designed for multiple candidate cells, which can be used to report measurement results based on SSB or CSI-RS. Multiple candidate cells can report different types of L1 measurement results, i.e., it supports mixed reporting of L1 measurement results from multiple candidate cells based on SSB and CSI-RS. The reported content must include at least one of the following:

[0099] (1) Relevant indication information indicating the L1 measurement results of multiple candidate cells included in the current MAC CE, wherein the method for indicating multiple candidate cells includes at least one of the following:

[0100] •1-1.1 The bitmap method is used to indicate whether the current MAC CE contains the L1 measurement results of the corresponding candidate cell.

[0101] •1-1.2 By reporting the number of candidate cells and the corresponding candidate cell ID, the current MAC CE is used to indicate the number of reported candidate cells and the specific candidate cells.

[0102] (2) Based on the multiple candidate cell information indicated in the MAC CE, the MAC CE also includes one or more L1 measurement result reporting entries for candidate cells. For each reported measurement result reporting entry for a candidate cell, at least one of the following indication fields is included: the reporting amount of the L1 measurement result of the candidate cell (indicating based on either SSB or CSI-RS RSRP), the reported candidate beam information, and the corresponding L1 measurement result.

[0103] In scheme 1-1.1, a bitmap indication method is used, and the MAC CE contains one or more of the following fields, such as... Figure 2A As shown in the figure. In this embodiment, the first field corresponds to the first indicator field mentioned above, the second field corresponds to the second indicator field, the third field corresponds to the eighth indicator field, the fourth field corresponds to the sixth indicator field, and the fifth field corresponds to the seventh indicator field.

[0104] (1) First field: This field, using a bitmap, indicates whether the L1 measurement results of the corresponding candidate cell are reported in the current MAC CE. For example, if Ci is set to 1, it means that the L1 measurement results of candidate cell i are reported, i.e., the MAC CE includes an entry for the L1 measurement results of a single candidate cell corresponding to candidate cell i; if Ci is set to 0, it means that the L1 measurement results of candidate cell i are not reported, i.e., the MAC CE does not contain an entry for the L1 measurement results of a single candidate cell corresponding to candidate cell i. Here, i can directly indicate the candidate cell ID i, or indicate the i-th candidate cell ID after all candidate cell IDs configured by the current UE are arranged in ascending or descending order. The candidate cell ID is configured by the network side through RRC signaling (such as the candidate cell ID corresponding to ltm-CandidateId). The number of bits occupied by the first field depends on the maximum number of candidate cell IDs that can be configured by the network side; this embodiment uses 8 bits as an example for explanation.

[0105] (2) One or more entries for reporting L1 measurement results of a single candidate cell, each entry including at least one or more of the following fields.

[0106] • Second field: Used to indicate whether the L1 measurement result reported in the current entry for a single candidate cell is based on SSB or CSI-RS, occupying 1 bit; for example, if this field is 1, it means that the measurement result is reported based on SSB, and if this field is 0, it means that the L1 measurement result is reported based on CSI-RS; or, if this field is 0, it means that the measurement result is reported based on SSB, and if this field is 1, it means that the L1 measurement result is reported based on CSI-RS.

[0107] • The third field: Indicates via bitmap whether the current entry for a single candidate cell contains the reference signal index number of the candidate beam and the corresponding L1 measurement result for that candidate cell; for example, Bi indicates whether the reference signal and corresponding L1 measurement result indicated by the i-th SSB-index or i-th CSI-RS index of the candidate cell, as indicated in the fourth field, exist in the current entry. Taking the reporting of L1 measurement results based on SSB as an example, setting the B1 field to 1 indicates... Figure 1 The first SSB-index field (i.e., byte 3, Oct 3) and the corresponding L1 RSRP field (i.e., byte 4, Oct 4) exist; setting the B2 field to 0 indicates that... Figure 1 The second SSB-index field (i.e., the 5th byte, Oct 5) and the second SSB-

[0108] The L1 RSRP field corresponding to the index (i.e., the 6th byte, Oct 6) does not exist. Using a bitmap approach, L1 measurement results for different numbers of beams within a single candidate cell can be flexibly reported. The number of bits occupied by the Bi field depends on the maximum number of candidate beams that a single candidate cell can report in the L1 measurement report as set by the network side. In this embodiment, taking a maximum of 4 beams reported by a single candidate cell as an example, Bi occupies 4 bits.

[0109] • Fourth field: Indicates the index value of the reference signal based on SSB or CSI-RS contained in the LTMCSI resource set for L1 measurement corresponding to a single candidate cell, occupying 100 bits. N maxThis represents the maximum number of SSBs or NZP CSI-RS resources supported by the network side in a resource set. For example, if each SSB-based resource set currently supports a maximum of 64 SSBs, then the ssb-index is (0~63), occupying 6 bits for indication. Considering MAC CE byte alignment, 2 reserved bits are added, denoted by R. For example, for L1 measurement based on CSI-RS, each resource set supports a maximum of 192 NZPCSI-RS resources, then the CSI-RS index is (0~191), occupying 8 bits for indication. (In this embodiment, SSB-Index1 or CSI-RSIndex1 indicates the first SSB reported in the current entry for a single cell.)

[0110] The index or the first CSI-RS index does not necessarily mean that the index value is 1.

[0111] • Fifth field: Indicates the corresponding SSB-index or CSI-index indicated in the fourth field.

[0112] The L1 RSRP of the RS index; the L1 RSRP field is the reference signal received power value of the corresponding L1 measurement based on SSB or CSI-RS, occupying 7 bits. Furthermore, to further save signaling overhead, differential RSRP can also be reported. Differential RSRP is the reference signal received power value of the L1 measurement based on SSB or CSI-RS quantized to 4 bits, and the reference RSRP is the largest L1-RSRP value in the relevant L1-RSRP reporting entry.

[0113] • Considering byte alignment principles, additional reserved bits R are used for bits less than 8 bits.

[0114] Scheme 1-1.2 adopts the method of reporting the number of candidate cells and the corresponding candidate cell IDs. The MAC CE contains one or more of the following fields, such as... Figure 2B As shown. In this embodiment, the first field corresponds to the third indicator field mentioned above, the second field corresponds to the fourth indicator field, the third field corresponds to the fifth indicator field, the fourth field corresponds to the second indicator field, the fifth field corresponds to the sixth indicator field, and the sixth field corresponds to the seventh indicator field.

[0115] (1) First field: This field indicates the number of candidate cells reported in the current MAC CE minus 1; that is, if this field is set to 0, the number of candidate cells reported is 1; if this field is set to 1, the number of candidate cells reported is 2, and so on. This field occupies 100 bits. Where L maxThis represents the maximum number of configurable LTM candidate cells supported by the network side. For example, if a maximum of 8 LTM candidate cells are supported, this field occupies 3 bits; if a maximum of 16 LTM candidate cells are supported, this field occupies 4 bits, and so on. In this embodiment, a maximum of 8 candidate cells are configured, occupying 3 bits, as an example.

[0116] (2) One or more entries for reporting L1 measurement results of a single candidate cell, each entry including at least one or more of the following fields.

[0117] • Second field: Used to indicate the candidate cell corresponding to the L1 measurement result reported in the current entry. The value of this field plus one equals the reported LTM candidate cell ID;

[0118] The LTM candidate cell ID is configured by the network side via RRC signaling (e.g., LTM-).

[0119] CandidateId corresponds to the candidate cell ID; the number of bits occupied is...

[0120] Where L max This represents the maximum number of configurable LTM candidate cells supported by the network side. For example, if a maximum of 8 LTM candidate cells are supported, this field occupies 3 bits; if a maximum of 16 LTM candidate cells are supported, this field occupies 4 bits, and so on.

[0121] In this embodiment, a maximum of 8 candidate cells are configured, occupying 3 bits, as an example.

[0122] • Third field: Used to indicate whether the L1 measurement result reported in the current entry for a single candidate cell is based on SSB or CSI-RS, occupying 1 bit; for example, if this field is 1, it means that the measurement result is reported based on SSB, and if this field is 0, it means that the L1 measurement result is reported based on CSI-RS; or, if this field is 0, it means that the measurement result is reported based on SSB, and if this field is 1, it means that the L1 measurement result is reported based on CSI-RS.

[0123] • Fourth field: Indicates, via bitmap, whether the current entry for a single candidate cell contains the reference signal index number of the candidate beam for that candidate cell and the corresponding L1 measurement result; for example, Bi indicates whether the reference signal and corresponding L1 measurement result indicated by the i-th SSB-index or i-th CSI-RS index of the candidate cell, as indicated in the first field, exist in the current entry. The above reporting is based on CSI-

[0124] Taking the L1 measurement result of RS as an example, if the B1 field is set to 1, it indicates that the first CSI in Figure 2 is...

[0125] The RS index field (i.e., byte 3, Oct 3) and the L1 RSRP field (i.e., byte 4, Oct 4) corresponding to the first CSI-RS index exist; setting the B2 field to 0 indicates that... Figure 1 The second CSI-RS index field (i.e., byte 5, Oct 5) and the corresponding L1 RSRP field (i.e., byte 6, Oct 6) do not exist. Using a bitmap approach, L1 measurement results for different numbers of beams within a single candidate cell can be flexibly reported. The number of bits occupied by the Bi field depends on the maximum number of candidate beams that a single candidate cell can report in the L1 measurement report as set by the network side. In this embodiment, taking a maximum of 4 beams reported by a single candidate cell as an example, Bi occupies 4 bits.

[0126] • Fifth field: Indicates the index value of the reference signal based on SSB or CSI-RS contained in the LTM CSI resource set for L1 measurement corresponding to a single candidate cell, occupying 100 bits. N max This represents the maximum number of SSBs or NZP CSI-RS resources supported by the network side in a resource set. For example, if each SSB-based resource set currently supports a maximum of 64 SSBs, then the SSB-index is (0-63), requiring only 6 bits for indication. Considering MAC CE byte alignment, two reserved bits are added, denoted by R. For example, for L1 measurement based on CSI-RS, each resource set supports a maximum of 192 NZPCSI-RS resources, then the CSI-RS index is (0-191), requiring only 8 bits for indication. (In this embodiment, SSB-Index1 or CSI-RS...)

[0127] Index1 indicates the first SSB reported in the current entry for a single cell.

[0128] The index or the first CSI-RS index does not necessarily mean that the index value is 1.

[0129] • Sixth field: Indicates the corresponding SSB-index or CSI-index indicated in the fifth field.

[0130] The L1 RSRP of the RS index; the L1 RSRP field is the reference signal received power value of the corresponding L1 measurement based on SSB or CSI-RS, occupying 7 bits. Furthermore, to further save signaling overhead, differential RSRP can also be reported. Differential RSRP is the reference signal received power value of the L1 measurement based on SSB or CSI-RS quantized to 4 bits, and the reference RSRP is the largest L1-RSRP value in the relevant L1-RSRP reporting entry.

[0131] • Considering byte alignment principles, additional reserved bits R are used for bits less than 8 bits.

[0132] Option 1-2 as follows Figures 3A-3C As shown, for reporting L1 measurement results from multiple candidate cells, two types of MACCEs are designed, one for reporting SSB-based measurement results and the other for reporting CSI-RS-based measurement results. Different LCID or eLCID values ​​are introduced to identify the MACCE for reporting SSB-based L1 measurement results or CSI-RS-based L1 measurement results, respectively. When multiple candidate cells report the same type of L1 measurement results, the reported content must include at least one of the following:

[0133] (1) Relevant indication information indicating the L1 measurement results of multiple candidate cells included in the current MAC CE, wherein the method for indicating multiple candidate cells includes at least one of the following:

[0134] •1-2.1 The bitmap method is used to indicate whether the current MAC CE contains the L1 measurement results of the corresponding candidate cell.

[0135] • 1-2.2 The method of superimposing a beam bitmap on a candidate cell bitmap indicates whether the current MAC CE contains the L1 measurement results of the corresponding candidate cell; the length of the beam bitmap depends on the cell bitmap and only contains the corresponding candidate beam information of the candidate cell indicated by the cell bitmap.

[0136] •1-2.3 By using a fixed number of beam bitmaps, it indicates whether the current MAC CE contains L1 measurement results of the corresponding beams of multiple candidate cells.

[0137] (2) Based on the multiple candidate cell information indicated in the MAC CE, the MAC CE also includes one or more L1 measurement result reporting entries for candidate cells. For each reported measurement result reporting entry for a candidate cell, at least one of the following indication fields is included: the reported candidate beam information and the corresponding L1 measurement result.

[0138] Scheme 1-2.1 adopts a bitmap indication method. The MAC CE contains one or more of the following fields, such as... Figure 3A As shown, (a) and (b) respectively illustrate MAC CE formats for reporting L1 measurement results based on SSB and for reporting L1 measurement results based on CSI-RS. In these embodiments, the first field corresponds to the first indication field, the second field corresponds to the second indication field, the third field corresponds to the sixth indication field, and the fourth field corresponds to the seventh indication field.

[0139] (1) First field: This field, using a bitmap, indicates whether the L1 measurement results of the corresponding candidate cell have been reported in the current MAC CE. The specific method is similar to the method of using a bitmap to indicate multiple candidate cells in Scheme 1-1, and will not be described in detail here.

[0140] (2) One or more entries for reporting L1 measurement results of a single candidate cell, each entry including at least one or more of the following fields.

[0141] • Second field: Indicates, via bitmap, whether the current entry for a single candidate cell contains the reference signal index number of the candidate beam and the corresponding L1 measurement result for that candidate cell. For MAC CEs reporting L1 measurement results based on SSB, Bi indicates whether the reference signal indicated by the i-th SSB-index of the candidate cell and the corresponding L1 measurement result, as indicated in the third field, exist in the current entry; for MAC CEs reporting L1 measurement results based on CSI-RS, Bi indicates whether the reference signal indicated by the i-th CSI-RS index of the candidate cell and the corresponding L1 measurement result, as indicated in the third field, exist in the current entry. Taking the MAC CE reporting L1 measurement results based on SSB as an example, setting B1 to 1 indicates that the first SSB-index field (i.e., the 3rd byte, Oct 3) and the corresponding L1RSRP field (i.e., the 4th byte, Oct 4) in Figure 3-(a) exist; setting B2 to 0 indicates that the second SSB-index field (i.e., the 5th byte, Oct 5) and the corresponding L1 RSRP field (i.e., the 6th byte, Oct 6) in Figure 3-(a) do not exist. Alternatively, it indicates whether the reference signal indicated by the i-th CSI-RS index and the corresponding L1 measurement result exist in the current entry. The number of bits occupied by the Bi field depends on the maximum number of candidate beams that a single candidate cell can report in the L1 measurement report set by the network side. In some embodiments, taking a single candidate cell supporting a maximum of 4 beams as an example, Bi occupies 4 bits.

[0142] • Third field: Indicates the index value of the reference signal based on SSB or CSI-RS contained in the LTM CSI resource set for L1 measurement corresponding to a single candidate cell, occupying 100 bits. N max This represents the maximum number of SSBs or NZP CSI-RS resources supported by the network side in a resource set. For example, if each SSB-based resource set currently supports a maximum of 64 SSBs, then the SSB-index is (0~63), requiring only 6 bits for indication. Considering MAC CE byte alignment, two reserved bits are added, denoted by R. For example, for L1 measurements based on CSI-RS, each resource set supports a maximum of 192 NZPCSI-RS resources, then the CSI-RS index is (0~191), requiring 8 bits for indication. (In this embodiment, SSB-Index1 or CSI-RS Index1 indicates the first SSB-index or the first CSI-RS index reported in the current entry for a single cell, and does not imply that the index value is 1.)

[0143] • Fourth field: Indicates the corresponding SSB-index or CSI-index indicated in the third field.

[0144] The L1 RSRP of the RS index; the L1 RSRP field is the reference signal received power value of the corresponding L1 measurement based on SSB or CSI-RS, occupying 7 bits. Furthermore, to further save signaling overhead, differential RSRP can also be reported. Differential RSRP is the reference signal received power value of the L1 measurement based on SSB or CSI-RS quantized to 4 bits, and the reference RSRP is the largest L1-RSRP value in the relevant L1-RSRP reporting entry.

[0145] • Considering byte alignment principles, additional reserved bits R are used for bits less than 8 bits.

[0146] Scheme 1-2.2 adopts a candidate cell bitmap overlay beam bitmap indication method. The MAC CE contains one or more of the following fields, such as... Figure 3B As shown, the left portion and the right portion (i.e. Figure 3B Example (b) of the document provides MAC CE formats for reporting L1 measurement results based on SSB and for reporting L1 measurement results based on CSI-RS. In this example, the first field corresponds to the first indication field, the second field corresponds to the second indication field, the third field corresponds to the sixth indication field, and the fourth field corresponds to the seventh indication field.

[0147] (1) The first field: In a bitmap manner, it is used to indicate whether the L1 measurement results of the corresponding candidate cell are reported in the current MAC CE. The specific method is similar to the method of using a bitmap to indicate multiple candidate cells in Solution 1-1, and will not be elaborated here.

[0148] (2) The second field: In a bitmap manner, it indicates whether the reference signal index number of the candidate beam of the relevant candidate cell and the corresponding L1 measurement results are included in the current MAC CE. When the first field indicates that there are measurement results of the candidate cell, the second field includes the corresponding Bi field of the candidate cell; the number of bits occupied by the Bi field of a single candidate cell is the same, depending on the maximum number of candidate beams reported for a single candidate cell in the L1 measurement report set by the network side. Taking the example that a single candidate cell supports reporting up to 4 beams at most, then the Bi corresponding to a single candidate cell occupies 4 bits. The total number of bits occupied by the second field depends on the number of candidate cells indicated to exist in the first field. When the first field indicates that the current MAC CE includes the measurement results of 1 candidate cell, the second field occupies 4 bits. When the first field indicates that the current MAC CE includes the measurement results of 2 candidate cells, the second field occupies 8 bits, and so on. The Bi fields of multiple candidate cells are arranged in ascending or descending order of the candidate cell IDs indicated to exist (i.e., x > y > z or x < y < z in Figure 4). The specific indication method of the Bi field is similar to the indication method of Bi in the second field of Embodiment 1 of Solution 1-2, and will not be elaborated here.

[0149] (2) One or more entries (Entries) for reporting the L1 measurement results of a single candidate cell, and each entry includes at least one or more of the following fields.

[0150] · The third field: It indicates the index value of the reference signal based on SSB or CSI-RS included in the LTMCSI resource set for L1 measurement corresponding to a single candidate cell, and the number of bits occupied is N max is the maximum value of the number of SSBs in a resource set supported by the network side or the number of NZP CSI-RS resources; for example, currently each resource set based on SSB supports up to 64 SSBs, then ssb-index is (0~63), and 6 bits are occupied to indicate. Considering the byte alignment of the MAC CE, 2 reserved bits are supplemented and represented by R; for example, for L1 measurement based on CSI-RS, each resource set supports up to 192 NZP CSI-RS resources, then CSI-RS index is (0~191), and 8 bits are occupied to indicate. (In the embodiments of the present disclosure, SSB-Index1 or CSI-RSIndex1 indicates the first SSB reported in the entry for the current single cell)

[0151] The index or the first CSI-RS index does not necessarily mean that the index value is 1.

[0152] • Fourth field: Indicates the corresponding SSB-index or CSI-index indicated in the third field.

[0153] The L1 RSRP of the RS index; the L1 RSRP field is the reference signal received power value of the corresponding L1 measurement based on SSB or CSI-RS, occupying 7 bits. Furthermore, to further save signaling overhead, differential RSRP can also be reported. Differential RSRP is the reference signal received power value of the L1 measurement based on SSB or CSI-RS quantized to 4 bits, and the reference RSRP is the largest L1-RSRP value in the relevant L1-RSRP reporting entry. Considering byte alignment principles, supplementary reserved bits R are used for bits less than 8 bits.

[0154] Scheme 1-2.3 uses a fixed number of beam bitmaps for indication. The MAC CE contains one or more of the following fields, such as... Figure 3C As shown, (a) and (b) respectively illustrate MAC CE formats for reporting L1 measurement results based on SSB and for reporting L1 measurement results based on CSI-RS. In these embodiments, the first field corresponds to the fifth indication field, the second field corresponds to the sixth indication field, and the third field corresponds to the seventh indication field.

[0155] (1) First field: This field, using a bitmap, indicates whether the L1 measurement results of the corresponding candidate cell are reported in the current MAC CE. For Bi-m, i represents the candidate cell ID i, or the i-th candidate cell ID after all candidate cell IDs configured by the current UE are sorted in ascending or descending order; m represents the m-th beam reported by candidate cell i. For example, if Bi-m is set to 1, it means that the L1 measurement results of candidate cell i are reported, that is, the MAC CE includes an entry for the L1 measurement results of a single candidate cell corresponding to candidate cell i, and the entry reports the measurement results of the m-th candidate beam of candidate cell i; if Bi-m is set to 0, it means that the MAC CE does not include the L1 measurement results of the m-th beam of candidate cell i. If at least one field in the Bi-m field of a single candidate cell is indicated as 1, it means that the current MAC CE reports the measurement results of that candidate cell; if all fields in the Bi-m field of a single candidate cell are 0, it means that the current MAC CE does not report the measurement results of that candidate cell. The number of bits occupied by the Bi-m field of a single candidate cell is the same, depending on the maximum number of candidate beams that a single candidate cell can report in the L1 measurement report set by the network side. The total number of bits occupied by the first field is equal to the product of the maximum number of candidate cell IDs that can be configured by the network side and the maximum number of candidate beams that a single candidate cell can report in the L1 measurement report set by the network side. In this embodiment, taking 8 candidate cells as an example, and a single candidate cell supporting a maximum of 4 beams to report, the Bi-m field corresponding to a single candidate cell occupies 4 bits, and the total number of bits occupied by the first field is 32.

[0156] (2) One or more entries for reporting L1 measurement results of a single candidate cell, each entry including at least one or more of the following fields.

[0157] • Second field: Indicates the index value of the reference signal based on SSB or CSI-RS contained in the LTMCSI resource set for L1 measurement corresponding to a single candidate cell, occupying 100 bits. N max This represents the maximum number of SSBs or NZP CSI-RS resources supported by the network side in a resource set. For example, if each SSB-based resource set currently supports a maximum of 64 SSBs, then the ssb-index is (0~63), occupying 6 bits for indication. Considering MAC CE byte alignment, 2 reserved bits are added, denoted by R. For example, for L1 measurement based on CSI-RS, each resource set supports a maximum of 192 NZPCSI-RS resources, then the CSI-RS index is (0~191), occupying 8 bits for indication. (In this embodiment, SSB-Index1 or CSI-RSIndex1 indicates the first SSB reported in the current entry for a single cell.)

[0158] The index or the first CSI-RS index does not necessarily mean that the index value is 1.

[0159] • Third field: Indicates the corresponding SSB-index or CSI-index indicated in the second field.

[0160] The L1 RSRP of the RS index; the L1 RSRP field is the reference signal received power value of the corresponding L1 measurement based on SSB or CSI-RS, occupying 7 bits. Furthermore, to further save signaling overhead, differential RSRP can also be reported. Differential RSRP is the reference signal received power value of the L1 measurement based on SSB or CSI-RS quantized to 4 bits, and the reference RSRP is the largest L1-RSRP value in the relevant L1-RSRP reporting entry.

[0161] • Considering byte alignment principles, additional reserved bits R are used for bits less than 8 bits.

[0162] Based on the above schemes 1-1 and 1-2, the L1 measurement results can be flexibly reported in the LTM mechanism. The L1 measurement results of multiple candidate cells that meet the triggering conditions can be reported based on MAC CE, ensuring that the UE reports effective L1 measurement reports in a timely manner, saving unnecessary overhead and terminal power consumption, and assisting the network side in LTM handover decision and candidate beam management, thereby improving network performance and user experience.

[0163] In some embodiments, in addition to carrying the L1 measurement results of candidate cells that meet the L1 measurement reporting conditions, the L1 measurement report may also carry the measurement results of the serving cell.

[0164] In related technologies, L1 measurement reports can only simultaneously report the measurement results of the serving cell when the serving cell is configured as a candidate cell. For event-triggered L1 measurement reports, the network side understands the current L1 measurement results of the serving cell corresponding to the relevant event, which helps assist the base station in making decisions. Based on conventional serving cell CSI reporting, it is difficult to guarantee that the measurement results of the candidate cell and the current reference serving cell reach the base station simultaneously, which will bring additional processing latency. Furthermore, for different candidate cells (such as candidate cell 1 and candidate cell 2), the network side may configure the same event criteria (such as the beam quality of the candidate cell being higher than threshold 1 and the beam quality of the serving cell being lower than threshold 2). When both candidate cell 1 and candidate cell 2 meet the event criteria, the L1 measurement results of candidate cell 1 and 2 can be reported through a single MAC CE. Furthermore, for candidate cells 1 and 2, the event criteria configured by the network side are associated with the same serving cell (such as PCell), so the measurement results of PCell can be reported in the same MAC CE, thereby better assisting the network side in LTM decision-making and beam management.

[0165] In some embodiments, the L1 measurement report may carry the L1 measurement results of one serving cell, which may be a PCell or a PSCell. In some embodiments, the L1 measurement report may carry the L1 measurement results of multiple serving cells, i.e., carrying the measurement results of both PCell and PSCell, thereby increasing the amount of information available to the network side, facilitating network side decision-making, and improving the convenience, efficiency, and accuracy of network side processing.

[0166] In some embodiments, the L1 measurement result of a single serving cell in the L1 measurement report can be the L1 measurement result of a single beam, i.e., the L1 measurement result of the serving beam. In some embodiments, the L1 measurement result of a single serving cell in the L1 measurement report can include the L1 measurement results of multiple beams, such as including the L1 measurement results of at least one other beam in addition to the L1 measurement results of the serving beam, thereby increasing the amount of information that the network side can obtain and facilitating network side decision-making.

[0167] In some embodiments, the measurement results for each candidate cell carried in the L1 measurement report may involve one or more beams of that candidate cell. If only one beam is involved, then that beam is a candidate beam that meets the L1 measurement reporting conditions, thereby ensuring that the network side receives the measurement results of the candidate beam that meets the L1 measurement reporting conditions while minimizing the amount of reported information; if multiple beams are involved, then at least one candidate beam that meets the L1 measurement reporting conditions is included among the multiple beams, thereby facilitating the provision of more reference information about the candidate cell to the network side.

[0168] In some embodiments, the MAC CE can indicate and carry the measurement results of the serving cell through multiple indication fields. The information related to the measurement results of the serving cell carried in the MAC CE includes at least one of the following:

[0169] The ninth indication field indicates the type of the serving cell in the L1 measurement results, including primary cell PCell or primary-secondary cell PSCell.

[0170] Indicates the tenth indication field of the L1 RSRP of the serving cell.

[0171] The MAC CE in the above embodiment can facilitate the network side to identify and read the L1 RSRP of the serving cell, thereby improving the reliability of the network side's reading.

[0172] The MAC CE carrying the measurement results of the serving cell may also include fields related to the measurement results of the candidate cell in any of the embodiments above, so as to realize the synchronous reporting of the measurement results of the candidate cell and the serving cell.

[0173] In some embodiments, the ninth indication field occupies 1 bit. For example, setting this field to 0 indicates reporting the measurement result of PCell, and setting it to 1 indicates reporting the measurement result of PSCell; or, setting this field to 1 indicates reporting the measurement result of PCell, and setting it to 0 indicates reporting the measurement result of PSCell.

[0174] In some embodiments, the tenth indication field occupies 7 bits to carry the L1 RSRP of the serving cell's beam. In some embodiments, the tenth indication field occupies 4 bits to carry the differential RSRP, thereby further saving signaling overhead. The differential RSRP is a 4-bit reference signal received power value based on SSB or CSI-RS L1 measurement, and the reference RSRP is the largest L1-RSRP value in the relevant L1-RSRP reporting entry. If the ninth indication field indicates a PCell, then the field corresponds to the reference signal received power value based on SSB or CSI-RS L1 measurement of the serving beam of the PCell; if the ninth indication field indicates a PSCell, then the field corresponds to the reference signal received power value based on SSB or CSI-RS L1 measurement of the serving beam of the PSCell; whether it is based on SSB or CSI-RS depends on the indication of the second indication field.

[0175] In some embodiments, the L1 measurement result of the serving cell carried in the MAC CE is the L1 measurement result of the current serving beam of the serving cell, that is, the tenth indication field mentioned above only carries the L1 measurement result of the current serving beam.

[0176] In some embodiments, the L1 measurement results of the serving cell carried in the MAC CE are L1 measurement results of multiple beams of the serving cell, which may include the L1 measurement results of the current serving beam. The tenth indication field carries the L1 measurement results of multiple serving beams, thereby increasing the amount of information about the serving cell that the network side can obtain, which facilitates network side decision-making.

[0177] In some embodiments, the MAC CE also includes at least one of the following:

[0178] The twelfth indication field indicates whether multiple beams of the serving cell are carried and the corresponding L1 measurement results;

[0179] The thirteenth indication field of a beam in the indicating service cell.

[0180] Based on this embodiment, the MAC CE can carry L1 measurement reports of multiple beams of the serving cell and identify them through the twelfth and thirteenth indication fields, which facilitates the network side to identify the correspondence between measurement results and beams, thereby improving the convenience and reliability of decision-making.

[0181] In some embodiments, the thirteenth indication field indicates the beam of the serving cell through the SSB-based reference signal index value in the CSI resource set corresponding to the serving cell, and the tenth indication field indicates the L1 RSRP corresponding to the SSB-based reference signal index value in the thirteenth indication field.

[0182] In some embodiments, the thirteenth indication field indicates the beam of the serving cell based on the reference signal index value of CSI-RS in the CSI resource set corresponding to the serving cell, and the tenth indication field indicates the L1RSRP corresponding to the reference signal index value of CSI-RS in the thirteenth indication field.

[0183] In some embodiments, the indication field for the serving cell in the MAC CE further includes an eleventh indication field indicating the type of reference signal on which the L1 measurement report of the serving cell is based. The type of reference signal includes SSB or CSI-RS. This indication field is similar to the eighth indication field mentioned above, except that it corresponds to the cell type; the eighth indication field corresponds to a candidate cell, and the eleventh indication field corresponds to the serving cell. If the eleventh indication field indicates that the type of reference signal is SSB, then the thirteenth indication field indicates the beam of the serving cell based on the SSB-based reference signal index value in the CSI resource set corresponding to the serving cell, and the tenth indication field indicates the L1 RSRP corresponding to the SSB-based reference signal index value in the thirteenth indication field. If the eleventh indication field indicates that the type of reference signal is CSI-RS, then the thirteenth indication field indicates the beam of the serving cell based on the CSI-RS-based reference signal index value in the CSI resource set corresponding to the serving cell, and the tenth indication field indicates the L1 RSRP corresponding to the CSI-RS-based reference signal index value in the thirteenth indication field.

[0184] In some embodiments, corresponding to the above-described MAC CE carrying measurement results of at least one candidate cell and measurement results of a serving cell, the MAC CE in the measurement report reporting method of this disclosure can, for example, be as shown in various embodiments of Scheme 2 below.

[0185] Option 2: As Figures 4A-4B 5A-5B Figure 6 ,as well as Figures 7A-7C As shown, a variable-length MAC CE is used to report the L1 measurement results of multiple candidate cells and the L1 measurement results of a single serving cell.

[0186] In Scheme 2, the event criteria configured for multiple candidate cells are associated with the same serving cell.

[0187] When the L1 measurement reporting conditions are met, the UE reports the MAC CE used for the L1 measurement report for LTM, which includes at least one of the following: L1 measurement results based on SSB of the LTM candidate cell and the corresponding serving cell that meet the reporting conditions, or L1 measurement results based on CSI-RS of the LTM candidate cell and the corresponding serving cell that meet the reporting conditions.

[0188] The specific format and content include at least one of the following:

[0189] (1) The MAC CE includes at least one of the following: serving cell and related beam indication field, reference signal index number corresponding to the serving cell beam and corresponding L1 measurement result field; candidate cell and related beam indication field, reference signal index number corresponding to the candidate cell beam and corresponding L1 measurement result field.

[0190] (2) The reporting of beamforming results for the serving cell includes at least one of the following:

[0191] • The serving cell only reports the measurement results of the current serving beam, that is, the serving cell only reports the measurement results of 1 beam;

[0192] • The service area reported multiple beam measurement results.

[0193] (3) For the reporting of beam results of candidate cells, a similar method to that in Scheme 1 is adopted, and will not be repeated here;

[0194] (4) For multiple candidate cells and their corresponding serving cells, the design of MAC CE can also be considered:

[0195] • One MAC CE format, suitable for reporting based on SSB or CSI-

[0196] The measurement results of RS; multiple candidate cells and associated serving cells need to report the same type of measurement results (based on SSB or based on CSI-RS); MAC CE can also simultaneously report the measurement results of other candidate cells that are not configured to be triggered by events or the measurement results of candidate cells that are not associated with serving cells in other configured event criteria (such as the event criterion configured for candidate cells being that the candidate cell beam is higher than the threshold value), and can report different types of measurement results, thereby achieving flexible reporting.

[0197] Two types of MAC CEs are used to report measurement results based on SSB or CSI-RS, respectively. Different LCID or eLCID values ​​are introduced to identify the MAC CE reporting L1 measurement results based on SSB or L1 measurement results based on CSI-RS. Each MAC CE can also simultaneously report measurement results of other candidate cells that are not configured with event triggering or other candidate cell measurement results that are not associated with the serving cell in the configured event criteria (e.g., the event criterion configured for the candidate cell is that the candidate cell beam is above a threshold), but these must be of the same type.

[0198] This enables flexible reporting.

[0199] Option 2-1 Figure 4A , 4B As shown, only the current serving beam measurement results of the serving cell are reported. For multiple candidate cells and their corresponding serving cells, one MAC CE format is used, which can be applied to reporting measurement results based on SSB or CSI-RS. The MAC CE contains one or more of the following fields. In this embodiment, the first field corresponds to the ninth indication field mentioned above, the second field corresponds to the eleventh indication field, and the third field corresponds to the tenth indication field.

[0200] (1) First field: used to indicate whether the serving cell in the L1 measurement results reported in the current MAC CE corresponds to PCell or PSCell; it occupies 1 bit; for example, if this field is set to 0, it means that the measurement results of PCell are reported, and if it is set to 1, it means that the measurement results of PSCell are reported; or, if this field is set to 1, it means that the measurement results of PCell are reported, and if it is set to 0, it means that the measurement results of PSCell are reported.

[0201] (2) Second field: This field is used to indicate whether the measurement results reported in the current MAC CE are L1 measurement results based on SSB or CSI-RS, and it occupies 1 bit. For example, if this field is 1, it means that the measurement results are reported based on SSB, and if this field is 0, it means that the L1 measurement results are reported based on CSI-RS. Alternatively, if this field is 0, it means that the measurement results are reported based on SSB, and if this field is 1, it means that the L1 measurement results are reported based on CSI-RS.

[0202] (3) Third field: Indicates the L1 RSRP of the serving cell; occupies 7 bits; if the first field indicates PCell, then this field corresponds to the reference signal received power value of the serving beam of PCell based on SSB or CSI-RS L1 measurement; if the first field indicates PSCell, then this field corresponds to the reference signal received power value of the serving beam of PSCell based on SSB or CSI-RS L1 measurement; based on SSB or based on CSI-RS depends on the indication of the second field.

[0203] (4) The relevant fields of the candidate cell are similar to those in Scheme 1, and will not be repeated here.

[0204] Down Figures 4A-4B The document presents various MAC CE implementations for reporting measurement results of multiple candidate cells and a single serving cell, wherein the candidate cell reporting methods correspond to several different methods in Scheme 1.

[0205] Option 2-2. Figures 5A-5B As shown, the serving cell reports multiple beam measurement results. For multiple candidate cells and their corresponding serving cells, a MAC CE format is designed, applicable to reporting measurement results based on SSB or CSI-RS. The MAC CE includes one or more of the following fields. In this embodiment, the first field corresponds to the ninth indication field mentioned above, the second field corresponds to the eleventh indication field, the third field corresponds to the twelfth indication field, the fourth field corresponds to the thirteenth indication field, and the fifth field corresponds to the tenth indication field.

[0206] (1) First field: used to indicate whether the serving cell in the L1 measurement results reported in the current MAC CE corresponds to PCell or PSCell; it occupies 1 bit; for example, if this field is set to 0, it means that the measurement results of PCell are reported, and if it is set to 1, it means that the measurement results of PSCell are reported; or, if this field is set to 1, it means that the measurement results of PCell are reported, and if it is set to 0, it means that the measurement results of PSCell are reported.

[0207] (2) Second field: This field is used to indicate whether the measurement results reported in the current MAC CE are L1 measurement results based on SSB or CSI-RS, and it occupies 1 bit. For example, if this field is 1, it means that the measurement results are reported based on SSB, and if this field is 0, it means that the L1 measurement results are reported based on CSI-RS. Alternatively, if this field is 0, it means that the measurement results are reported based on SSB, and if this field is 1, it means that the L1 measurement results are reported based on CSI-RS.

[0208] (3) Third field: Indicates whether the MAC CE contains the L1 measurement result entry corresponding to the serving cell via a bitmap method; for example, Pi indicates whether the reference signal indicated by the i-th SSB-index or the i-th CSI-RS index of the serving cell and the corresponding L1 measurement result exist in the MAC CE. Taking the reporting of L1 measurement results based on SSB as an example, setting the P1 field to 1 indicates that... Figure 5A -(a) The first SSB-index field (i.e., byte 3, Oct 3) and the corresponding L1 RSRP field (i.e., byte 4, Oct 4) of the first SSB-index exist; setting the P2 field to 0 indicates that... Figure 5A In (a), the second SSB-index field (i.e., byte 5, Oct 5) and the corresponding L1RSRP field (i.e., byte 6, Oct 6) do not exist. Using a bitmap method, L1 measurement results for different numbers of beams under the serving cell can be flexibly reported. The number of bits occupied by the Pi field depends on the network-side configuration. In this embodiment, taking a single cell supporting a maximum of 4 beams for reporting as an example, Pi occupies 4 bits.

[0209] (4) The L1 measurement result entries corresponding to the serving cell shall include at least the following fields:

[0210] • Fourth field: Indicates the index value of the reference signal based on SSB or CSI-RS contained in the CSI resource set corresponding to the serving cell, occupying 100 bits.

[0211] N maxThis represents the maximum number of SSBs or NZP CSI-RS resources supported by the network side in a resource set. For example, if each SSB-based resource set currently supports a maximum of 64 SSBs, then the SSB-index is (0~63), requiring only 6 bits for indication. Considering MAC CE byte alignment, two reserved bits are added, denoted by R. For example, for L1 measurements based on CSI-RS, each resource set supports a maximum of 192 NZP CSI-RS resources, then the CSI-RS index is (0~191), requiring 8 bits for indication. (In the example below, SSB-Index1 or CSI-RS Index1 indicates the first SSB-index or the first CSI-RS index reported in the MAC CE, and does not mean that the index value is 1.)

[0212] • Fifth field: Indicates the L1 RSRP corresponding to the SSB-index or CSI-RS index indicated in the fourth field; the L1 RSRP field is the reference signal received power value based on the corresponding SSB-index or CSI-RS L1 measurement, occupying 7 bits. Furthermore, to further save signaling overhead, differential RSRP can also be reported. The differential RSRP is quantized to 4 bits based on the SSB-index or CSI-RS index.

[0213] The RSRP is the reference signal received power value measured by L1, and the reference RSRP is the largest L1-RSRP value in the relevant L1-RSRP reported entry. Considering byte alignment principles, supplementary reserved bits R are used for bits less than 8 bits.

[0214] (5) The relevant fields of the candidate cell are similar to those in Scheme 1, and will not be repeated here.

[0215] Down Figures 5A-5B The document presents various MAC CE implementations for reporting measurement results of multiple candidate cells and a single serving cell, wherein the candidate cell reporting methods correspond to several different methods in Scheme 1.

[0216] Option 2-3. Figure 6 As shown, the serving cell only reports the measurement results of the current serving beam. For multiple candidate cells and their corresponding serving cells, two types of MAC CEs are designed to report measurement results based on SSB or CSI-RS, respectively. Different LCID or eLCID values ​​are introduced to identify the MAC CEs reporting L1 measurement results based on SSB or L1 measurement results based on CSI-RS, respectively. Since the serving cell only reports the L1 measurement results of the current serving beam, the MAC CE must include at least the following fields. In this embodiment, the first field corresponds to the ninth indication field mentioned above, and the second field corresponds to the tenth indication field.

[0217] (1) The L1 measurement result entry for the current serving beam of the serving cell shall include at least the following fields:

[0218] • First field: Used to indicate whether the serving cell in the L1 measurement results reported in the current MAC CE corresponds to PCell or PSCell; occupies 1 bit; for example, setting this field to 0 indicates that the measurement results of PCell are reported, and setting it to 1 indicates that the measurement results of PSCell are reported; or, setting this field to 1 indicates that the measurement results of PCell are reported, and setting it to 0 indicates that the measurement results of PSCell are reported.

[0219] • Second field: Indicates the L1 RSRP of the serving cell; occupies 7 bits; if the first field indicates PCell, this field corresponds to the reference signal received power value of the serving beam of PCell based on SSB (or CSI-RS) L1 measurement; if the first field indicates PSCell, this field corresponds to the reference signal received power value of the serving beam of PSCell based on SSB (or CSI-RS) L1 measurement.

[0220] (3) The relevant fields of the candidate cell are similar to those in Scheme 1, and will not be repeated here.

[0221] Figure 6 Examples of MAC CE reporting L1 measurement results based on SSB and MAC CE reporting L1 measurement results based on CSI-RS are given in (b) and (a), respectively.

[0222] Option 2-4. Figures 7A-7C As shown, the serving cell reports multiple beam measurement results. For multiple candidate cells and their corresponding serving cells, two types of MAC CEs are designed to report measurement results based on SSB or CSI-RS, respectively. Different LCID or eLCID values ​​are introduced to identify the MAC CEs reporting L1 measurement results based on SSB or L1 measurement results based on CSI-RS. Since the serving cell can report L1 measurement results for multiple beams, the MAC CE must include at least the following fields. In this embodiment, the first field corresponds to the ninth indication field mentioned above, and the second field corresponds to the twelfth indication field.

[0223] (1) First field: used to indicate whether the serving cell in the L1 measurement results reported in the current MAC CE corresponds to PCell or PSCell; it occupies 1 bit; for example, if this field is set to 0, it means that the measurement results of PCell are reported, and if it is set to 1, it means that the measurement results of PSCell are reported; or, if this field is set to 1, it means that the measurement results of PCell are reported, and if it is set to 0, it means that the measurement results of PSCell are reported.

[0224] (2) Second field: Indicates whether the MAC CE contains the L1 measurement result entry corresponding to the serving cell via a bitmap method; for example, Pi indicates whether the reference signal indicated by the i-th SSB-index (or i-th CSI-RS index) of the serving cell and the corresponding L1 measurement result exist in the MAC CE. Taking the reporting of SSB-based L1 measurement results as an example, setting the P1 field to 1 indicates that... Figure 7A (a) The first SSB-index field (i.e., byte 3, Oct 3) and the corresponding L1 RSRP field (i.e., byte 4, Oct 4) of the first SSB-index exist; setting the P2 field to 0 indicates that... Figure 7A In (a), the second SSB-index field (i.e., byte 5, Oct 5) and the corresponding L1RSRP field (i.e., byte 6, Oct 6) do not exist. Using a bitmap method, L1 measurement results for different numbers of beams under the serving cell can be flexibly reported. The number of bits occupied by the Pi field depends on the network-side configuration. In this embodiment, taking a single cell supporting a maximum of 4 beams for reporting as an example, Pi occupies 4 bits.

[0225] (3) The fields included in the L1 measurement result entries corresponding to the serving cell are similar to those in Scheme 2-2, and will not be repeated here.

[0226] (4) The relevant fields of the candidate cell are similar to those in Scheme 1, and will not be repeated here.

[0227] Figures 7A-7C The document presents various MAC CE implementations for reporting measurement results of multiple candidate cells and a single serving cell, wherein the candidate cell reporting methods correspond to several different methods in Scheme 1.

[0228] In some embodiments, with Figures 7A-7C Part (a): Taking the MAC CE used to report L1 measurement results based on SSB as an example, the MAC CE contains at least one or more of the following fields, wherein the first field corresponds to the ninth indication field and the second field corresponds to the tenth indication field.

[0229] (1) First field: used to indicate whether the serving cell in the L1 measurement results reported in the current MAC CE corresponds to PCell or PSCell; it occupies 1 bit; for example, if this field is set to 0, it means that the measurement results of PCell are reported, and if it is set to 1, it means that the measurement results of PSCell are reported; or, if this field is set to 1, it means that the measurement results of PCell are reported, and if it is set to 0, it means that the measurement results of PSCell are reported.

[0230] (2) Second field: Indicates the L1 RSRP of the serving cell; occupies bit; if the first field indicates PCell, then this field corresponds to the reference signal received power value of the serving beam of PCell based on SSB L1 measurement; if the first field indicates PSCell, then this field corresponds to the reference signal received power value of the serving beam of PSCell based on SSB L1 measurement.

[0231] (3) Fields 3 to 6: Used to report the measurement results of multiple candidate beams of a single candidate cell. Similar to the method of the first to fourth fields of MAC CE used to report the L1 measurement results based on SSB in Scheme 1-2, the multi-beam measurement results of the candidate cell are carried in the manner of Scheme 1-2.1, 1-2.2 and 1-2.3 respectively. They will not be described in detail here.

[0232] In the embodiment shown in Scheme 2 above, L1 measurement results of multiple candidate cells and L1 measurement results of a single serving cell are reported through a single MAC CE, wherein the event criteria configured for multiple candidate cells must be associated with the same serving cell. When candidate cells associated with different serving cells simultaneously meet the reporting conditions for L1 measurement reports, Scheme 2 requires reporting to multiple MAC CEs. To address this issue, in some embodiments of the measurement report reporting method disclosed herein, the MAC CE can carry L1 measurement results of one or more beams of multiple serving cells. The indication field for the serving cell in the MAC CE further includes:

[0233] The fourteenth indication field indicates the number of serving cells corresponding to the L1 measurement results carried.

[0234] The number of serving cells can be one, namely PCell or PSCell; or two, namely PCell and PSCell.

[0235] Based on the method in this embodiment, by designing a variable-length MAC CE, the L1 measurement results of multiple candidate cells and multiple serving cells are reported. This enables a single MAC CE to carry the L1 measurement results of different serving cells when candidate cells are associated with different serving cells, thereby further improving information transmission efficiency and reducing signaling burden.

[0236] In some embodiments, when the number of serving cells corresponding to the L1 measurement results carried in the fourteenth indication field is greater than 1, the ninth indication field indicates the serving cell type corresponding to the first (or second) serving cell in the L1 measurement results, which can be specifically determined according to network side configuration or pre-specified.

[0237] In some embodiments, the number of twelfth indication fields is the same as the number of serving cells, and the twelfth indication fields corresponding to different serving cells are located in the same or adjacent fields, and the arrangement order is the same as the arrangement order of the tenth indication fields carrying the L1 RSRP of the corresponding serving cell. The twelfth indication field indicates whether it carries the indication of multiple beams of the serving cell and the corresponding L1 measurement results.

[0238] In some embodiments, when the L1 measurement reporting conditions are met, the UE reports the L1 measurement report for LTM using the following MAC CE format, including at least one set of LTM candidate cells and corresponding serving cells L1 measurement results based on SSB that meet the reporting conditions, or one set of LTM candidate cells and corresponding serving cells L1 measurement results based on CSI-RS that meet the reporting conditions.

[0239] Option 3: The specific format and content of the MAC CE carrying L1 measurement results of one or more beams of multiple serving cells include at least one of the following.

[0240] (1) The MAC CE includes at least the number of reported serving cells, the relevant beam indication domain of each serving cell and one or more candidate cells associated with it, and the corresponding L1 measurement results.

[0241] (2) The beamforming results for each serving cell shall be reported, including at least one of the following:

[0242] • The serving cell only reports the measurement results of the current serving beam, that is, the serving cell only reports the measurement results of 1 beam;

[0243] • The service area reported multiple beam measurement results.

[0244] (3) For the reporting of beam results of candidate cells, a similar method to that in Scheme 1 is adopted, which will not be repeated here.

[0245] (4) For multiple candidate cells and their corresponding serving cells, the design of MAC CE can also be considered:

[0246] • One MAC CE format, suitable for reporting based on SSB or CSI-

[0247] The measurement results of RS; multiple candidate cells and associated serving cells need to report the same type of measurement results (based on SSB or based on CSI-RS); MAC CE can also simultaneously report the measurement results of other candidate cells that are not configured to be triggered by events or the measurement results of candidate cells that are not associated with serving cells in other configured event criteria (such as the event criterion configured for candidate cells being that the candidate cell beam is higher than the threshold value), and can report different types of measurement results, thereby achieving flexible reporting.

[0248] Two types of MAC CEs are used to report measurement results based on SSB or CSI-RS, respectively. Different LCID or eLCID values ​​are introduced to identify the MAC CEs reporting L1 measurement results based on SSB or L1 measurement results based on CSI-RS. Each MAC CE can also simultaneously report other candidate cell measurement results that are not configured with event triggers or other candidate cell measurement results that are not associated with the serving cell in the configured event criteria (e.g., the event criterion configured for the candidate cell is that the candidate cell beam is above a threshold value), but the same type of measurement results must be reported, thus achieving flexible reporting.

[0249] (5) Methods for indicating multiple serving cells include: indicating the number of serving cells reported in the current MAC CE (1 or 2) and indicating the type of serving cell (PCell or PSCell).

[0250] For situations where the serving cell reports a single or multiple beams, defines one type of MAC CE to support the reporting of different measurements (based on SSB or CSI-RS), or defines two types of MAC CE to report measurement results based on SSB or CSI-RS respectively.

[0251] Figures 8A-8H A specific implementation of the MAC CE format in Scheme 3 is given. In each embodiment, the MAC CE includes at least one or more fields from the following fields, wherein the first field corresponds to the fourteenth indication field and the second field corresponds to the ninth indication field.

[0252] (1) First field: Used to indicate the number of serving cells involved in the L1 measurement results reported in the current MAC CE; considering that the LTM mechanism currently only supports changing the PCell or changing the PSCell, the serving cells involved include the PCell and PSCell. In this embodiment, 1 bit is used as an example. The value of this field plus 1 is the number of serving cells reported in the MAC CE. That is, if this field is 0, it means that the L1 measurement results of 1 serving cell are reported; if this field is 1, it means that the L1 measurement results of 2 serving cells are reported.

[0253] (2) Second field: used to indicate whether the L1 measurement result of the first group of serving cells reported in the current MAC CE is PCell or PSCell; for example, if this field is set to 0, it means that the measurement result of the first group of serving cells reported is PCell, and if this field is 1, it means that the measurement result of the first group of serving cells reported is PSCell; or, if this field is set to 0, it means that the measurement result of the first group of serving cells reported is PSCell, and if this field is set to 1, it means that the measurement result of the first group of serving cells reported is PCell.

[0254] (3) Other fields: The relevant beam indication fields and corresponding L1 measurement results for each serving cell and one or more candidate cells associated with it, including at least one of the following:

[0255] • The L1 measurement result entries for the service cell are similar to those in Scheme 2, and will not be described again.

[0256] • The L1 measurement result entries for candidate cells are similar to those in Scheme 1 and will not be described again.

[0257] In some embodiments, when the MAC CE includes a first indication field (such as schemes 1-1.1, 1-2.1, 1-2.2), if the number of serving cells corresponding to the L1 measurement results carried by the fourteenth indication field is greater than 1, then the first indication field indicating the candidate cells corresponding to the L1 measurement results carried by the MAC CE corresponds one-to-one with the serving cells.

[0258] In some embodiments, when the MAC CE includes a third indication field (such as Scheme 1-1.2), if the number of serving cells corresponding to the L1 measurement results carried by the fourteenth indication field is greater than 1, then the third indication field indicating the number of candidate cells corresponding to the L1 measurement results carried by the MAC CE corresponds one-to-one with the serving cells.

[0259] In some embodiments, when the MAC CE includes a fifth indication field (such as Scheme 1-2.3), if the number of serving cells corresponding to the L1 measurement results indicated by the fourteenth indication field is greater than 1, then the fifth indication field indicating whether the MAC CE carries the L1 measurement results of one or more beams of each candidate cell corresponds one-to-one with the serving cell.

[0260] Based on the method in the embodiments shown above, the first, third, and fifth indication fields used to indicate the candidate cell can correspond one-to-one with the serving cell, thereby facilitating the network side to identify the correspondence between the candidate cell and the serving cell and making correct decisions on the network side.

[0261] In some embodiments, the first indication field, the third indication field, or the fifth indication field corresponding to different serving cells are located in the same or adjacent fields, and the arrangement order is the same as the arrangement order of the sixth indication field carrying the corresponding serving cell L1 RSRP. After receiving the message, the network side can determine all candidate cells by reading consecutive or closely spaced fields, and then determine the corresponding serving cell according to the order, thereby improving information reading efficiency.

[0262] Figures 8A-8H This is a schematic diagram of an embodiment of Scheme 3. This example is not a complete example of MAC CE in Scheme 3, but only an example of some cases.

[0263] In Scheme 3-1, such as Figure 8A As shown, the serving cell reports single-beam L1 measurement results based on SSB or CSI-RS in one MAC CE format.

[0264] In Scheme 3-2, such as Figure 8B As shown, the serving cell reports a single beam and defines one MAC CE format to report L1 measurement results based on SSB or CSI-RS;

[0265] In scheme 3-3, such as Figure 8C As shown, the serving cell reports multi-beam and defines one MAC CE format to report L1 measurement results based on SSB or CSI-RS;

[0266] In schemes 3-4, such as Figure 8D As shown, the serving cell reports multi-beam and defines one MAC CE format to report L1 measurement results based on SSB or CSI-RS;

[0267] In options 3-5, such as Figure 8E As shown, the serving cell reports single-beam and defines two MAC CE formats to report L1 measurement results based on SSB or CSI-RS respectively;

[0268] In schemes 3-6, such as Figure 8F As shown, the serving cell reports multi-beam and defines two MAC CE formats to report L1 measurement results based on SSB or CSI-RS respectively;

[0269] In schemes 3-7, such as Figure 8G As shown, the serving cell reports multi-beam and defines two MAC CE formats to report L1 measurement results based on SSB or CSI-RS respectively;

[0270] In schemes 3-8, such as Figure 8H As shown, the serving cell reports multi-beam and defines two MAC CE formats to report L1 measurement results based on SSB or CSI-RS respectively.

[0271] In some embodiments, the twelfth indication field corresponding to the same serving cell is located in the same or adjacent field as the first indication field, such as schemes 3-3, 3-6, and 3-8. The main difference between these three schemes is whether they include the CSI-RS / SSB identifier and the identification method of the candidate cell RSRP. For details, please refer to the embodiments in schemes 1 and 2.

[0272] In some embodiments, the twelfth indication field and the third indication field corresponding to the same serving cell are located in the same or adjacent fields, as shown in Schemes 3-4.

[0273] In some embodiments, the third indication field is located between the ninth and tenth indication fields, as shown in Scheme 3-2.

[0274] In some embodiments, the first indication field and the tenth indication field corresponding to the same serving cell are located in the same or adjacent fields, as shown in Scheme 3-1.

[0275] In some embodiments, the fields in which the first indication field corresponding to different serving cells is located are the same or adjacent, and the first indication field is located after the tenth indication field, as shown in Schemes 3-5.

[0276] In some embodiments, the fields in which the fifth indication field corresponding to different serving cells is located are the same or adjacent, and the fifth indication field is located after the tenth indication field, wherein the first indication field indicates the candidate cell corresponding to the L1 measurement result carried in the MAC CE, as shown in Schemes 3-7.

[0277] Based on the MAC CE in the embodiment of Scheme 3, it is possible to report the L1 measurement results of candidate cells and the L1 measurement results of at least one serving cell through a single MAC CE. By carrying the L1 measurement results of different serving cells through a single MAC CE, information transmission efficiency can be further improved and signaling burden can be reduced.

[0278] This disclosure also proposes a measurement report reporting device, in some embodiments, such as Figure 9 As shown in the image.

[0279] Measurement unit 91 is capable of performing Layer 1 (L1) measurements on user equipment.

[0280] The sending unit 92 can send an L1 measurement report via the MAC CE when it determines that the L1 measurement reporting conditions are met. The L1 measurement report has the capability to carry the L1 measurement results of multiple candidate cells, and can flexibly carry the L1 measurement results of at least one candidate cell according to actual needs. The sending unit 92 can execute the method in any embodiment of step S12 above. In some embodiments, the MAC CE can be as shown in any embodiment above.

[0281] The measurement report reporting device disclosed herein can carry event-triggered L1 measurement reports through a MAC CE, avoiding the occupation of uplink UCI resources. This addresses the issue of UCI resource scarcity while avoiding restrictions on packets via UCI reporting, thus improving the flexibility of L1 measurement reporting. The MAC CE can carry measurement results from multiple candidate cells, thereby improving the flexibility and reliability of LTM handover decisions and candidate beam management on the network side, ultimately enhancing network performance and user experience.

[0282] A schematic diagram of one embodiment of the measurement report reporting device disclosed herein is shown below. Figure 10As shown, the measurement report reporting device includes a memory 1001 and a processor 1002. The memory 1001 can be a disk, flash memory, or any other non-volatile storage medium. The memory stores instructions from the corresponding embodiments of the measurement report reporting method described above. The processor 1002 is coupled to the memory 1001 and can be implemented as one or more integrated circuits, such as a microprocessor or microcontroller. The processor 1002 executes the instructions stored in the memory, improving the flexibility of L1 measurement result reporting.
