Description

Technical Field

[0001] This disclosure relates to the field of communication technology, and in particular to a method, apparatus and storage medium for reporting measurement reports of user equipment. 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 candidate cell configuration information set by the network and reports the results. The network then determines whether cell handover needs to be triggered based on the reported Layer 1 measurements and instructs the UE to perform the handover process via Layer 2 signaling (Media Access Control Unit MAC CE). Compared to traditional handover processes based on Layer 3 measurement reporting, the LTM process does not support event-triggered measurement reporting, and periodic reporting incurs unnecessary signaling overhead. To further improve the performance of the LTM mechanism and reduce the signaling overhead of Layer 1 L1 measurement reporting, 3GPP will conduct research on event-triggered L1 measurement and reporting mechanisms in Release 19 to enhance LTM performance. Summary of the Invention

[0048] The technical solutions of this disclosure will be further described in detail below with reference to the accompanying drawings and embodiments.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] To address the aforementioned issues, this disclosure proposes a method, apparatus, and storage medium for reporting measurement reports from user equipment, enabling more flexible L1 measurement reporting, resolving the resource shortage problem of UCI-based reporting, saving uplink UCI resources, and achieving flexible reporting.

[0053] Flowcharts of some embodiments of the user equipment measurement report reporting method disclosed herein are as follows: Figure 1 As shown.

[0054] In step S11, the user equipment performs an L1 measurement.

[0055] In step S12, if the L1 measurement reporting conditions are met, an L1 measurement report is sent via MAC CE.

[0056] In some embodiments, the L1 measurement report carries the L1 measurement results of candidate cells that meet the L1 measurement reporting conditions. In some embodiments, the L1 measurement results of candidate cells that do not meet the L1 measurement reporting conditions are not carried in the L1 measurement report. This helps to reduce resource overhead while facilitating the network side to quickly locate candidate cells that meet the L1 measurement reporting conditions, thereby improving the convenience and efficiency of network side processing.

[0057] In some embodiments, each MAC CE carries only the L1 measurement results of one candidate cell, which reduces the amount of information that a single message needs to carry and the amount of resources required, while facilitating analysis and use by the network side.

[0058] In some embodiments, the L1 measurement report may carry not only the L1 measurement results of candidate cells that meet the L1 measurement reporting conditions, but also the measurement results of the serving cell. In related technologies, the measurement results of the serving cell can only be reported simultaneously in the L1 measurement report when the serving cell is configured as a candidate cell. By using the method in this embodiment, carrying the measurement results of the serving cell in event-triggered L1 measurement reports helps the network side understand the current L1 measurement results of the corresponding serving cell (or reference cell) in the relevant event, thereby facilitating network side decision-making and improving the convenience, efficiency, and accuracy of network side processing.

[0059] In some embodiments, the candidate cell measurement results carried in the L1 measurement report may involve one or more beams of the candidate cell. If only one beam is involved, then the 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.

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

[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... maxThen, 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 above embodiment, the event-triggered L1 measurement report is carried through MAC CE, avoiding the occupation of uplink UCI resources. While solving the problem of UCI resource shortage, it avoids the restriction of messages by using UCI reporting, and improves the flexibility of L1 measurement reporting.

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

[0066] The first indication field indicates the candidate cell corresponding to the L1 measurement report, for example, carrying information related to the candidate cell ID;

[0067] A second indication field indicating whether one or more beams of candidate cells are carried in the MAC CE and the corresponding L1 measurement results, for example, 0 and 1 values ​​occupying a predetermined space, the number of 1 (or 0) corresponding to the candidate beams related to the measurement results carried in the MAC CE;

[0068] A third indication field that indicates a candidate beam of a candidate cell, such as a unique identifier for the candidate beam;

[0069] The fourth indication field indicates the L1 reference signal received power RSRP corresponding to the candidate beam indicated in the third indication field.

[0070] The MAC CE in the above embodiment can facilitate network-side identification and reading of L1RSRP, thereby improving the reliability of network-side reading.

[0071] In some embodiments, the length of the first indication field is matched with the upper limit of the number of LTM candidate cells, thereby achieving a unique identifier for the candidate cells and improving the accuracy of the network side in determining candidate cells.

[0072] 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.

[0073] In some embodiments, the measurement result carried in the MAC CE is obtained by measuring the SSB as a reference signal. The third 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 fourth indication field indicates the L1 RSRP corresponding to the SSB-based reference signal index value in the third indication field, thereby facilitating accurate interpretation of the measurement results by the network side. The length occupied by the third indication field matches the number of SSB resources in the resource set configured by the network side.

[0074] In some embodiments, the measurement result carried in the MAC CE is obtained by measuring CSI-RS as a reference signal. The third 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 fourth indication field indicates the L1 RSRP corresponding to the CSI-RS-based reference signal index value in the third indication field. This facilitates accurate determination of the reference signal type by the network side and accurate interpretation of the measurement results. The length occupied by the third indication field matches the number of CSI-RS resources in the resource set configured by the network side.

[0075] In some embodiments, the second indication field indicates, via a bitmap, whether the MAC CE carries indications of one or more beams of the candidate cell and the corresponding L1 measurement results. This method improves the accuracy of the indication and enhances processing efficiency.

[0076] The second indicator field indicates the number of identifiers carrying candidate beams and corresponding L1 measurement results, the same as the number of the third and fourth indicator fields. The third and fourth indicator fields correspond one-to-one, and can be grouped together as a set. The MAC CE carries a combination of one or more third and fourth indicator fields, which helps improve the convenience and accuracy of network-side reading.

[0077] In some embodiments, the MAC CE further includes a fifth indication field indicating the type of reference signal on which the L1 measurement report is based. When the reference signal is an SSB, the third 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 fourth indication field indicates the L1 RSRP corresponding to the SSB-based reference signal index value in the third indication field; when the reference signal is a CSI-RS, the third 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 fourth indication field indicates the L1 RSRP corresponding to the CSI-RS-based reference signal index value in the third indication field.

[0078] 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.

[0079] In some embodiments, the MAC CE also includes reserved bits for byte alignment within the MAC CE.

[0080] In some embodiments, a schematic diagram of the MAC CE in the UE measurement report reporting method of this disclosure is shown below. Figures 2A-2D As shown in 3A and 3B.

[0081] Option 1-1. Figures 2A-2D As shown in the image.

[0082] For a single candidate cell, a MAC CE format is designed, which can be used to report measurement results based on SSB or CSI-RS. The MAC CE contains one or more of the following fields. In Scheme 1-1, the first field corresponds to the first indication field in the embodiment shown above, the second field corresponds to the fifth indication field, the third field corresponds to the second indication field, the fourth field corresponds to the third indication field, and the fifth field corresponds to the fourth indication field.

[0083] (1) First field: This field indicates the candidate cell corresponding to the L1 measurement result reported in the current MAC CE. The value of this field plus one equals the reported LTM candidate cell ID. The LTM candidate cell ID is configured by the network side via RRC signaling (e.g., the candidate cell ID corresponding to ltm-CandidateId); it occupies [number of bits]. 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. Figures 2A-2D The given example uses the first field, which occupies 3 bits.

[0084] (2) Second field: Used to indicate whether the L1 measurement result reported in the current MAC CE 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.

[0085] (3) Third field: Indicates whether the MAC CE contains the reference signal index number of the corresponding candidate beam and the corresponding L1 measurement result via bitmap; for example, Bi indicates whether the reference signal indicated by the i-th SSB-index or the i-th CSI-RS index indicated in the fourth field and the corresponding L1 measurement result exist in the MAC CE, where i is the identifier of the bit in the third field, and i is a natural number less than or equal to the bit length of the third field. Taking the above report of L1 measurement results based on SSB as an example, if B1 is 1, it means Figure 2A The first SSB-index field (i.e., byte 2, Oct 2) and the corresponding L1 RSRP field (i.e., byte 3, Oct 3) exist; setting the B2 field to 0 indicates that... Figure 2A The second SSB-index field (i.e., byte 4, Oct 4) and the corresponding L1RSRP field (i.e., byte 5, Oct 5) 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 can be reported by a single candidate cell in the event-triggered L1 measurement report set on the network side. Figure 2A , 2B In the example where a single candidate cell can report a maximum of 4 beams, Bi occupies 4 bits. When the number of candidate beams reported by a single candidate cell in the event-triggered L1 measurement report set by the network side is greater than 4 bits, it can be configured as follows: Figure 2C , 2D As shown in the diagram.

[0086] (4) Fourth 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 LTM candidate cell, occupying 100 bits. N maxThis represents the maximum number of SSBs or NZP CSI-RS resources supported by the network 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 diagram, 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 represent the value of that index.)

[0087] (5) Fifth field: Indicates the L1 RSRP of the corresponding SSB-index or CSI-RS index indicated in the fourth field; 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, in order to further save signaling overhead, differential RSRP can also be reported. The 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.

[0088] Considering byte alignment principles, additional reserved bits R are used for bits less than 8 bits.

[0089] In the above scheme, the MAC CE can optionally carry measurement information based on SSB reference signal or measurement information based on CSI-RS reference signal, which is identified by the second field, making it convenient for the network side to identify and improving the flexibility and compatibility of the UE.

[0090] Option 1-2. Figure 3A , 3B As shown in the image.

[0091] For a single candidate cell, 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, such as... Figure 3A , 3B As shown in the diagram. In Scheme 1-2, the first field corresponds to the first indicator field in the embodiment shown above, the second field corresponds to the second indicator field, the third field corresponds to the third indicator field, and the fourth field corresponds to the fourth indicator field.

[0092] MAC CE used for reporting L1 measurement results based on SSB, such as Figure 3A As shown, it contains at least one or more of the following fields.

[0093] (1) First field: This field indicates the candidate cell corresponding to the L1 measurement result reported in the current MAC CE. The value of this field plus one equals the reported LTM candidate cell ID. The LTM candidate cell ID is configured by the network side via RRC signaling (e.g., the candidate cell ID corresponding to ltm-CandidateId); it occupies [number of bits]. 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. Figure 3A The given example uses 3 bits.

[0094] (2) Second field: This field uses a bitmap to indicate whether the MAC CE contains the reference signal index number of the corresponding candidate beam and the corresponding L1 measurement result. For example, Bi indicates whether the reference signal of the i-th SSB-index indicated in the third field and the corresponding L1 measurement result exist in the MAC CE. For example, if the B1 field is set to 1, it means that the first SSB-index field (i.e., the 2nd byte, Oct 2) and the L1 RSRP field corresponding to the first SSB-index (i.e., the 3rd byte, Oct 3) in Figure 5 exist; if the B2 field is set to 0, it means that the second SSB-index field (i.e., the 4th byte, Oct 4) and the L1 RSRP field corresponding to the second SSB-index (i.e., the 5th byte, Oct 5) in Figure 5 do not exist. The bitmap method allows for flexible reporting of L1 measurement results for different numbers of beams under a single candidate cell. The number of bits occupied by the Bi field depends on the maximum number of candidate beams that can be reported by a single candidate cell in the event-triggered L1 measurement report set by the network side. Figure 3A In the example where a single candidate cell can report a maximum of 5 beams, Bi occupies 5 bits. When the number of candidate beams reported by a single candidate cell in the event-triggered L1 measurement report set by the network side exceeds 5 bits, it can be referenced... Figure 2C , 2D The second field is carried in a similar manner as shown.

[0095] (3) Third field: Indicates the index value of the SSB-based reference signal contained in the LTM CSI resource set for L1 measurement corresponding to a single LTM candidate cell, occupying 100 bits. N maxThis represents the number of SSBs in a resource set supported by the network side. For example, if each SSB-based resource set currently supports a maximum of 64 SSBs, then the ssb-index is (0~63), which can be indicated by 6 bits. Considering MAC CE byte alignment, 2 reserved bits are added, represented by R.

[0096] (4) Fourth field: Indicates the L1 RSRP of the corresponding SSB-index indicated in the third field; the L1 RSRP field is the reference signal received power value of the corresponding SSB-based L1 measurement, occupying 7 bits. Furthermore, in order to further save signaling overhead, differential RSRP can also be reported. The differential RSRP is the reference signal received power value of the CSI-RS or SSB-based L1 measurement quantized to 4 bits, and the reference RSRP is the largest L1-RSRP value in the relevant L1-RSRP reporting entry.

[0097] Considering byte alignment principles, additional reserved bits R are used for bits less than 8 bits.

[0098] MAC CE used for reporting L1 measurement results based on CSI-RS, such as Figure 3B As shown, it contains at least one or more of the following fields:

[0099] (1) First field: This field indicates the candidate cell corresponding to the L1 measurement result reported in the current MAC CE. The value of this field plus one equals the reported LTM candidate cell ID. The LTM candidate cell ID is configured by the network side via RRC signaling (e.g., the candidate cell ID corresponding to ltm-CandidateId); it occupies [number of bits]. 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. Figure 3B The given example uses 3 bits.

[0100] (2) Second field: Indicates whether the MAC CE contains the reference signal index number of the corresponding candidate beam and the corresponding L1 measurement result via bitmap method; for example, Bi indicates whether the reference signal of the i-th CSI-RS Index indicated in the third field and the corresponding L1 measurement result exist in the MAC CE. For example, if the B1 field is set to 1, it means that the first CSI-RS-index field (i.e., the 2nd byte, Oct 2) and the L1 RSRP field (i.e., the 3rd byte, Oct 3) corresponding to the first CSI-RS-index in Figure 6 exist; if the B2 field is set to 0, it means that the second CSI-RS index field (i.e., the 4th byte, Oct 4) and the L1 RSRP field (i.e., the 3rd byte, Oct 5) corresponding to the second CSI-RS-index in Figure 6 do not exist. Through bitmap method, it is possible to flexibly report the L1 measurement results of different numbers of beams under a single candidate cell. The number of bits occupied by the Bi field depends on the maximum number of candidate beams reported by a single candidate cell in the event-triggered L1 measurement report set by the network side. Figure 3B In the example where a single candidate cell can report a maximum of 5 beams, Bi occupies 5 bits. When the network side's event-triggered L1 measurement report specifies a maximum of 4 candidate beams reported by a single candidate cell, it can refer to... Figure 2C , 2D The second field is carried in a similar manner as shown.

[0101] (3) Third field: Indicates the index value of the CSI-RS-based reference signal contained in the LTM CSI resource set for L1 measurement corresponding to a single LTM candidate cell, occupying 100 bits. N max This represents the number of CSI-RS in a resource set supported by the network side. For example, for L1 measurements based on CSI-RS, if each resource set supports a maximum of 192 NZP CSI-RS resources, then the CSI-RS index is (0~191), occupying 8 bits for indication.

[0102] (4) Fourth field: Indicates the L1 RSRP corresponding to the CSI-RS-index indicated in the third field; the L1 RSRP field is the reference signal received power value of the corresponding CSI-RS-based L1 measurement, occupying 7 bits. Furthermore, in order to further save signaling overhead, differential RSRP can also be reported. The differential RSRP is the reference signal received power value of the CSI-RS-based L1 measurement quantized to 4 bits, and the reference RSRP is the largest L1-RSRP value in the relevant L1-RSRP reporting entry.

[0103] Considering byte alignment principles, additional reserved bits R are used for bits less than 8 bits.

[0104] In Schemes 1-1 and 1-2 above, the number of bits occupied by the corresponding indicator fields will change depending on the maximum number of configurable LTM candidate cells supported by the network side and the maximum number of candidate beams that can be reported for a single LTM candidate cell. When the number of bits is not a multiple of 8 bits, relevant reserved bits need to be added to ensure byte alignment, taking into account the byte alignment principle. The position of the reserved bits is not limited.

[0105] Based on the MAC CE reporting format in Schemes 1-1 and 1-2, the UE can flexibly report one or more candidate beam L1 measurement results not exceeding the network-side limit, according to the maximum number of candidate beams allowed to be reported by a single candidate cell as set by the network side.

[0106] Based on schemes 1-1 and 1-2, the system can support UEs in reporting only L1 measurement results for beams that meet the event triggering conditions, or in reporting L1 measurement results for beams that do not meet the triggering conditions or are not configured for event-triggered reporting. For a candidate cell, when the relevant beam quality (L1 RSRP based on CSI-RS or SSB) of that cell meets the event-based triggering conditions, the UE prioritizes reporting the L1 RSRP of the beams in that cell that meet the triggering reporting conditions. The system is further supported when the number of beams meeting the triggering conditions is greater than or equal to the maximum number N of reference signals (RS) reported by each cell in a single L1 measurement report entry configured on the network side. max When this happens, the UE can prioritize reporting the relevant L1 RSRP of the corresponding beam with better beam quality, that is, report the top N candidate cells. max The L1 RSRP corresponding to the best quality beam; when the number of beams satisfying the triggering condition is less than N. max When a UE reports the L1 RSRP of a candidate cell that meets the triggering conditions, it can also choose to report the L1 RSRP of other beams that do not meet the triggering reporting conditions or the L1 RSRP of other beams that are not configured for event-triggered reporting (the specifics may depend on the base station configuration).

[0107] Therefore, based on Scheme 1-1 and Scheme 1-2, flexible reporting of L1 measurement results in the LTM mechanism can be achieved. For example, it can support reporting only event-triggered L1 measurement results, or it can support mixed reporting of event-triggered L1 measurement results and regular L1 measurement results used for LTM, to assist the network side in making LTM decisions.

[0108] 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:

[0109] The sixth indication field indicates the type of the serving cell in the L1 measurement results. The type of serving cell includes primary cell PCell or primary-secondary cell PSCell.

[0110] Indicates the seventh indication field of the L1 RSRP of the serving cell.

[0111] 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.

[0112] 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 described above, so as to realize the synchronous reporting of the measurement results of the candidate cell and the serving cell. The seventh indication field is based on the same type of reference signal as the L1RSRP in the fourth indication field above, so that the measurement results in the same MAC CE are based on the same type of reference signal, reducing the measurement pressure on the network side and the UE side.

[0113] In some embodiments, if the MAC CE includes the aforementioned fifth indication field, which identifies the type of reference signal on which the measurement results carried in the MAC CE are based, then the type of reference signal on which the L1 RSRP of the serving cell is based matches the type of reference signal indicated in the fifth indication field, thereby facilitating the network side to correctly identify and process the measurement results.

[0114] 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 seventh indication field mentioned above only carries the L1 measurement result of the current serving beam.

[0115] 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 aforementioned seventh 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.

[0116] In some embodiments, the sixth 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.

[0117] In some embodiments, the seventh indication field occupies 7 bits to carry the L1 RSRP of the serving cell's beam. In some embodiments, the seventh 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 sixth 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 sixth 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.

[0118] In some embodiments, the indication field for the serving cell in the MAC CE further includes at least one of the following:

[0119] The eighth indication field indicates whether multiple beams of the serving cell are carried and the corresponding L1 measurement results. The length of the eighth indication field matches the upper limit of the number of beams reported by a single cell, so that the network side can clearly determine the number of beams related to the measurement report carried in the MAC CE and read the information of the corresponding length.

[0120] The ninth indication domain of a beam in the indicating service cell.

[0121] In this embodiment, the MAC CE has the ability to identify the number of beams related to the measurement results carried and to identify the serving beam, thereby facilitating the network side to accurately and quickly identify the L1 RSRP of the serving cell beam and improving the accuracy of information transmission and network side information reading.

[0122] In some embodiments, the eighth indication field uses a bitmap to indicate whether it carries indications of multiple beams of the serving cell and the corresponding L1 measurement results. This method can improve the accuracy of the indication and improve processing efficiency.

[0123] The eighth indication field carries the number of identifiers for the serving cell's beam and the corresponding L1 measurement results, the same as the number of the ninth and seventh indication fields. The ninth and seventh indication fields correspond one-to-one. Since the ninth and seventh indication fields are in a one-to-one correspondence, they can be grouped together. The MAC CE carries one or more combinations of the ninth and seventh indication fields, which improves the convenience and accuracy of network-side reading.

[0124] 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 ninth indication field indicates the serving cell beam using the SSB-based reference signal index value included in the LTM CSI resource set used for L1 measurement. The seventh indication field indicates the L1RSRP corresponding to the SSB-based reference signal index value in the ninth indication field, thereby facilitating accurate interpretation of the measurement results by the network side. The length occupied by the ninth indication field matches the number of SSB resources in the resource set configured by the network side.

[0125] In some embodiments, the measurement result carried in the MAC CE is obtained by measuring CSI-RS as a reference signal. The ninth indication field indicates the serving cell beam using the CSI-RS-based reference signal index value included 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 ninth indication field, thereby facilitating accurate interpretation of the measurement results by the network side. The length occupied by the ninth indication field matches the number of CSI-RS resources in the resource set configured by the network side.

[0126] In some embodiments, the MAC CE also includes reserved bits for byte alignment within the MAC CE.

[0127] In some embodiments, a schematic diagram of the MAC CE in the UE measurement report reporting method of this disclosure is shown below. Figures 4A-4B As shown in 5A-5B, 6A-6B, and 7A-7B, by using a variable-length MAC CE to simultaneously report the L1 measurement results of a single candidate cell and the L1 measurement results of the current serving cell, the network side can understand the measurement results of the candidate cell and the current L1 measurement results of the corresponding serving cell in related events, thereby assisting the base station in making decisions. Based on conventional serving cell CSI reporting, it cannot be guaranteed that the measurement results of the candidate cell and the current reference serving cell will reach the base station simultaneously, resulting in additional processing latency. The method in this embodiment can better assist the network side in LTM decision-making and beam management.

[0128] When the reporting conditions for L1 measurement reports are met, the UE reports the L1 measurement reports for LTM using the following MAC CE format, which includes at least one of the following: LTM candidate cells and corresponding serving cells based on SSB L1 measurement results that meet the reporting conditions, or LTM candidate cells and corresponding serving cells based on CSI-RS L1 measurement results that meet the reporting conditions. The specific format and content include any one of the following schemes 2-1 to 2-4.

[0129] Option 2-1. Figure 4A , 4B As shown in the image.

[0130] The serving cell only reports the measurement results of the current serving beam. For a single candidate cell and its corresponding serving cell, 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 Scheme 2-1, the first field corresponds to the sixth indication field in the embodiment shown above, the second field corresponds to the fifth indication field, the third field corresponds to the seventh indication field, the fourth field corresponds to the first indication field, the fifth field corresponds to the second indication field, the sixth field corresponds to the third indication field, and the seventh field corresponds to the fourth indication field.

[0131] (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.

[0132] (2) Second field: Used to indicate whether the L1 measurement result reported in the current MAC CE 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.

[0133] (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.

[0134] (4) Fourth field: Used to indicate the candidate cell corresponding to the L1 measurement result reported in the current MAC CE. The value of this field plus one equals the reported LTM candidate cell ID; the LTM 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 is 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. Figures 4A-4B The given example uses 3 bits.

[0135] (5) Fifth field: Indicates, via bitmap, whether the MAC CE contains the reference signal index number of the corresponding candidate beam and the corresponding L1 measurement result; for example, Bi indicates whether the reference signal indicated by the i-th SSB-index or the i-th CSI-RS index indicated in the sixth field 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 B1 field to 1 indicates that... Figure 4A The first SSB-index field (i.e., byte 3, Oct 3) and the corresponding L1RSRP field (i.e., byte 4, Oct 4) of the first SSB-index exist; setting the B2 field to 0 indicates that... Figure 4A The second SSB-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 can be reported by a single candidate cell in the event-triggered L1 measurement report set on the network side. Figure 4A In the example where a single candidate cell can report a maximum of 4 beams, Bi occupies 4 bits. When the network side's event-triggered L1 measurement report specifies a maximum number of candidate beams reported by a single candidate cell that exceeds 4 bits, refer to... Figure 2C , 2D The second field is carried in a similar manner as shown.

[0136] (6) Sixth 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 LTM candidate cell, occupying 100 bits. Nmax represents the maximum number of SSBs or NZP CSI-RS resources supported by the network 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 NZP CSI-RS resources, then the CSI-RS index is (0-191), requiring only 8 bits for indication. Figure 4B As shown in the illustration. (In the illustrated embodiment, 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.)

[0137] (7) Seventh field: Indicates the L1 RSRP of the corresponding SSB-index or CSI-RS index indicated in the sixth field; 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. The 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 the byte alignment principle, a supplementary reserved bit R is used for bits less than 8 bits.

[0138] Option 2-2. Figure 5A , 5B As shown in the image.

[0139] The serving cell reports multiple beam measurement results. For a single candidate cell and its corresponding serving cell, 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 Scheme 2-2, the first field corresponds to the sixth indicator field in the embodiment shown above, the second field corresponds to the fifth indicator field, the third field corresponds to the eighth indicator field, the fourth field corresponds to the ninth indicator field, and the fifth field corresponds to the seventh indicator field. Fields six through nine are used to report multiple candidate beam measurement results for a single candidate cell, similar to the method for fields four through seven in Scheme 2.1, and will not be repeated here.

[0140] (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.

[0141] (2) Second field: Used to indicate whether the L1 measurement result reported in the current MAC CE 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.

[0142] (3) Third field: Indicates whether the MAC CE contains the reference signal index number of the serving cell beam and the corresponding L1 measurement result via bitmap method; for example, Pi indicates whether the reference signal and the corresponding L1 measurement result indicated by the i-th SSB-index or i-th CSI-RS index of the serving cell indicated in the fourth field 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 The first SSB-index field (i.e., byte 2, Oct 2) and the corresponding L1 RSRP field (i.e., byte 3, Oct 3) of the first SSB-index exist; setting the P2 field to 0 indicates that... Figure 5B The second SSB-index field (i.e., byte 4, Oct 4) and the corresponding L1 RSRP field (i.e., byte 5, Oct 5) do not exist. Using a bitmap method, L1 measurement results for different numbers of beams within the serving cell can be flexibly reported. The number of bits occupied by the Pi field depends on the network-side configuration. Figure 5A , 5B In this example, taking a single cell as an example where it supports reporting a maximum of 4 beams, Pi occupies 4 bits. When the number of serving cell beams reported is greater than 4 bits, refer to... Figure 2C , 2D The processing methods described herein will not be elaborated upon further.

[0143] (4) 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. Nmax represents the maximum number of SSBs or NZP CSI-RS resources supported by the network 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 NZP CSI-RS resources, then the CSI-RSindex is (0~191), requiring 8 bits for indication. (In the embodiment shown in the figure, 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.)

[0144] (5) Fifth field: Indicates the L1 RSRP corresponding to the SSB-index or CSI-RS index indicated in the third field; 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. The 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 the byte alignment principle, a supplementary reserved bit R is used for bits less than 8 bits.

[0145] Option 2-3. Figure 6A , 6B As shown in the image.

[0146] For scenarios involving simultaneous reporting of measurement results from the serving cell and a single candidate cell, 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. The serving cell only reports the L1 measurement results of its current serving beam. In schemes 2-3, the first field corresponds to the sixth indicator field in the above-described embodiment, the second field corresponds to the seventh indicator field, and the third to sixth fields are used to report multiple candidate beam measurement results of a single candidate cell. The method for the first to fourth fields of the MAC CE used to report L1 measurement results based on SSB in scheme 1.2 is similar and will not be repeated here.

[0147] The MAC CE used to report L1 measurement results based on SSB must contain at least one or more of the following fields, such as Figure 6A As shown.

[0148] (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.

[0149] (2) Second 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 L1 measurement based on SSB of the serving beam of PCell; if the first field indicates PSCell, then this field corresponds to the reference signal received power value of the L1 measurement based on SSB of the serving beam of PSCell.

[0150] (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 reporting the first to fourth fields of MAC CE based on SSB L1 measurement results in Scheme 1.2, it will not be described again.

[0151] The MAC CE used for reporting CSI-RS-based L1 measurement results must contain at least one or more of the following fields, such as: Figure 6B As shown.

[0152] (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.

[0153] (2) Second 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 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 CSI-RS L1 measurement.

[0154] (3) Third to sixth fields: used to report the measurement results of multiple candidate beams of a single candidate cell. The method is similar to the first to fourth fields of MAC CE used to report the L1 measurement results based on CSI-RS in Scheme 1.2, and will not be repeated here.

[0155] Option 2-4. Figure 7A , 7B As shown in the diagram. For scenarios where both serving cell and single candidate cell measurement results are reported simultaneously, 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. The serving cell can report L1 measurement results from multiple beams. In schemes 2-4, the first field corresponds to the sixth indication field in the above-described embodiment, the second field corresponds to the eighth indication field, the third field corresponds to the ninth indication field, the fourth field corresponds to the seventh indication field, and the fifth to eighth fields are similar to the first to fourth fields of the MAC CEs used for reporting L1 measurement results based on SSB in schemes 1-2, and will not be described again.

[0156] The MAC CE used for reporting SSB-based L1 measurement results must contain at least one or more of the following fields, such as Figure 7A As shown.

[0157] (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.

[0158] (2) Second field: Indicates whether the MAC CE contains the reference signal index number of the serving cell beam and the corresponding L1 measurement result via bitmap method; for example, Pi indicates whether the reference signal of the i-th SSB-index of the serving cell indicated in the third field and the corresponding L1 measurement result exist in the MAC CE. For example, if the P1 field is set to 1, it means that... Figure 7A The first SSB-index field (i.e., byte 2, Oct 2) and the corresponding L1 RSRP field (i.e., byte 3, Oct 3) exist; setting the P2 field to 0 indicates that... Figure 7A The second SSB-index field (i.e., byte 4, Oct 4) and the corresponding L1 RSRP field (i.e., byte 5, Oct 5) do not exist. Using a bitmap method, L1 measurement results for different numbers of beams within the serving cell can be flexibly reported. The number of bits occupied by the Pi field depends on the network-side configuration. Figure 7A In this example, taking a single cell as an example where it supports reporting a maximum of 4 beams, Pi occupies 4 bits. When the number of serving cell beams reported exceeds 4 bits, a method such as... Figure 2C , 2D Similar methods will not be described again.

[0159] (3) Third field: Indicates the index value of the SSB-based reference signal contained in the CSI resource set corresponding to the serving cell, occupying 100 bits. Nmax is the number of SSBs in a resource set supported by the network side; for example, if the current support is a maximum of 64 SSBs per SSB-based resource set, then the ssb-index is (0~63), which can be indicated by 6 bits. Considering MAC CE byte alignment, 2 reserved bits are added, represented by R.

[0160] (iv) Fourth field: Indicates the L1 RSRP corresponding to the SSB-index indicated in the third field; the L1 RSRP field is the reference signal received power value of the corresponding SSB-based L1 measurement, occupying 7 bits. Furthermore, to further save signaling overhead, differential RSRP can also be reported. The differential RSRP is the reference signal received power value of the SSB-based L1 measurement 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, a supplementary reserved bit R is used for bits less than 8 bits.

[0161] (5) Fields 5 to 8: Similar to the first to fourth fields of the MAC CE used to report L1 measurement results based on SSB in Scheme 1-2, and will not be described again.

[0162] The MAC CE used for reporting CSI-RS-based L1 measurement results must contain at least one or more of the following fields, such as: Figure 7B As shown.

[0163] (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.

[0164] (2) Second field: Indicates whether the MAC CE contains the reference signal index number of the serving cell beam and the corresponding L1 measurement result via bitmap method; for example, Pi indicates whether the reference signal of the i-th CSI-RSIndex of the serving cell and the corresponding L1 measurement result indicated in the third field exist in the MAC CE. For example, if the P1 field is set to 1, it means that... Figure 7BThe first CSI-RS Index field (i.e., byte 2, Oct 2) and the corresponding L1 RSRP field (i.e., byte 3, Oct 3) of the first CSI-RS Index exist; setting the P2 field to 0 indicates that... Figure 7B The second CSI-RS Index field (i.e., byte 4, Oct4) and the corresponding L1 RSRP field (i.e., byte 5, Oct 5) do not exist. Using a bitmap method, L1 measurement results for different numbers of beams within the serving cell can be flexibly reported. The number of bits occupied by the Pi field depends on the network-side configuration. Figure 7B In this example, taking a single cell as an example where it can report a maximum of 4 beams, Pi occupies 4 bits. When the number of serving cell beams reported is greater than 4, the following can be used: Figure 2C , 2D Similar methods will not be described again.

[0165] (3) Third field: Indicates the index value of the reference signal based on CSI-RS contained in the CSI resource set corresponding to the serving cell, occupying 100 bits. Nmax is the number of CSI-RS in a resource set supported by the network side; for example, for L1 measurement based on CSI-RS, each resource set supports a maximum of 192 NZP CSI-RS resources, then the CSI-RSindex is (0~191), occupying 8 bits for indication.

[0166] (iv) Fourth field: Indicates the L1 RSRP of the corresponding CSI-RS index indicated in the third field; the L1 RSRP field is the reference signal received power value of the corresponding CSI-RS-based L1 measurement, occupying 7 bits. Furthermore, to further save signaling overhead, differential RSRP can also be reported. The differential RSRP is the reference signal received power value of the CSI-RS-based L1 measurement 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, a supplementary reserved bit R is used for bits less than 8 bits.

[0167] (5) Fifth to eighth fields: Similar to the first to fourth fields of the L1 measurement result MAC CE based on CSI-RS in Scheme 1-2, they will not be described again.

[0168] In schemes 2-1, 2-2, 2-3, and 2-4, the reporting methods and principles for candidate cell measurement results are the same as in schemes 1-1 and 1-2. Based on the reporting of candidate cell measurement results, schemes 2-1, 2-2, 2-3, and 2-4 further support the simultaneous reporting of the serving cell's measurement results, including two methods: reporting the measurement results of the serving cell's current serving beam and flexibly reporting the measurement results of multiple beams of the serving cell. This provides the network side with diversified measurement results, assisting the network side in making LTM handover decisions and beam management.

[0169] The measurement report reporting method described above has been improved by making the following improvements to MAC CE to enable the reporting of L1 measurement results for multiple beams in candidate cells.

[0170] • Introducing the SSB / CSI-RS indication field: This field is used to indicate whether the L1 measurement result reported by the current MAC CE is based on SSB or CSI-RS, occupying 1 bit; This enables the MAC CE to flexibly report measurement results based on different reference signals, saving LCID or eLCID resources.

[0171] • Introducing a candidate cell indication field: This field is used to indicate the candidate cell corresponding to the L1 measurement results reported in the current MAC CE. The definition of this field and the method for determining the number of bits it occupies are also specified.

[0172] • An indicator field is introduced, which uses a bitmap method to indicate whether the MAC CE contains the reference signal index number of the corresponding candidate beam and the corresponding L1 measurement result, so as to flexibly report the L1 measurement results of different numbers of beams under a single candidate cell.

[0173] • Introduce a reference signal index value indication field to indicate 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 LTM candidate cell.

[0174] • Introduce a measurement result indication field to indicate the reference signal received power value of L1 measurement based on SSB or CSI-RS corresponding to the candidate cell.

[0175] • By defining different MAC CEs, measurement results based on SSB or CSI-RS can be reported separately, and measurement results based on different reference signals can be indicated by different LCIDs or eLCIDs.

[0176] Further improvements were made to MAC CE to enable the simultaneous reporting of measurement results of the serving cell, in addition to reporting L1 measurement results of multiple beams in the candidate cell.

[0177] • Introducing the PCell / PSCell 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.

[0178] • Introduce a measurement result indication field to indicate the reference signal received power value of the L1 measurement based on SSB or CSI-RS corresponding to the serving cell.

[0179] • When reporting measurement results of multiple beams of the serving cell, an indication field is introduced. The bitmap method indicates whether the MAC CE contains the reference signal index number of the corresponding beam of the serving cell and the corresponding L1 measurement result, so as to flexibly report the L1 measurement results of different numbers of beams under a single candidate cell.

[0180] • Introduce a reference signal index value indication field to indicate 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 the serving cell.
