[0100] In the prior art, mobility management typically involves a base station switching the target cell based on the Layer 3 (L3) measurement results reported by the terminal. Then, in the target cell, based on the beam management reporting results, the base station configures the Transmission Configuration Indicator (TCI) state via a Radio Resource Control (RRC) reconfiguration message, enabling the terminal to select an appropriate downlink beam for data reception. This beam management, such as L1 Reference Signal Received Power (RSRP) and L1 Signal to Interference plus Noise Ratio (SINR), is performed only within the serving cell; the terminal does not need to perform beam management-related measurements on neighboring cells.

[0101] To reduce the latency and signaling overhead caused by cell switching, one research direction is to develop L1-based inter-cell mobility. L1-based inter-cell mobility can be understood as the upper layer being unaware of the lower layer-based cell switching or beam switching toward neighboring cells. L1-based inter-cell mobility requires the terminal to perform L1 measurements and reports on neighboring cells (non-serving cells) / adjacent frequencies. Based on different terminal implementations, a mainstream implementation method is to integrate the L1 measurement module into the demodulation module. However, this method is limited by factors such as cost and complexity and can usually only support scenarios with good synchronization or a very limited number of neighboring cells that support L1 measurement. However, mobility scenarios require the terminal to be able to perform L1 measurements on multiple frequencies / cells. In other words, the mobility multi-frequency / cell measurement requirements conflict with the terminal's L1 measurement capabilities, resulting in a mismatch between the mobility multi-frequency / cell measurement requirements and the terminal's L1 measurement capabilities.

[0102] Based on this, in various embodiments of the present disclosure, the terminal performs L1 measurement and / or sends first information and / or second information to the network side, wherein the first information is related to the reception time difference and the second information is related to reporting and / or measurement; the network side receives the first information and / or second information sent by the terminal. In the above scheme, the terminal sends the first information and / or second information to the network side, which allows the network side to filter the cells / frequencies subsequently used for L1 measurement based on the first information and / or second information, making the L1 measurement more focused, so that the terminal uses its limited L1 measurement capabilities for the measurement of potential target cells, thereby improving the matching degree between the mobility multi-frequency / cell measurement requirements and the terminal's L1 measurement capabilities.

[0103] The present disclosure will be described in further detail below with reference to the accompanying drawings and embodiments.

[0104] The present disclosure provides a measurement method, which is applied to a terminal, also known as a user equipment (UE). As shown in FIG1 , the method includes:

[0105] Step 101: Perform L1 measurement; and / or

[0106] Sending first information to the network, wherein the first information is related to the reception time difference; and / or

[0107] Second information is sent to the network, where the second information is related to reporting and / or measurement.

[0108] Here, the L1 measurement includes at least one of L1-RSRP and L1-Signal to Interference plus Noise Ratio (SINR). In other words, the L1 measurement includes L1-RSRP measurement and / or L1-SINR measurement.

[0109] L1 measurements include at least one of intra-frequency L1 measurements and inter-frequency L1 measurements. L1 measurements are related to L1 / L2 triggered mobility (LTM). L1 / L2 triggered mobility can be described as layer 1 measurements for L1 / L2 triggered mobility. L1 / L2 can also be described as L1-L2.

[0110] The network can be described as network-side equipment or network equipment, which includes base stations.

[0111] The reception time difference is the time difference between the terminal receiving two cells, or it can be described as the difference in the reception time of the two cells, or it can be described as the time difference between the terminal receiving different cells. The reception time difference can also be extended to the time difference of more than two cells. The reception time difference can also be described as the time difference between cells. The reception time difference includes at least the reception time difference between the neighboring cell (or described as the target cell) and the serving cell (usually used in the same-frequency scenario), the time difference between two cells at the same frequency (or described as the time difference between the target cell and the reference cell, usually used in different-frequency scenarios, or described as the reception time difference between cells at the same frequency). That is, the reception time difference includes at least the reception time difference between the neighboring cell and the serving cell, and / or the time difference between two cells at the same frequency. In the same-frequency scenario or the same-frequency measurement scenario, the reception time difference can include the reception time difference between the neighboring cell and the serving cell, and / or the time difference between the neighboring cell and the serving cell at the same frequency; the reception time difference between the neighboring cell and the serving cell can be described as the reception time difference between the target cell and the serving cell. In inter-frequency scenarios or inter-frequency measurement scenarios, the reception time difference includes the time difference between two cells on the same frequency. The time difference between two cells on the same frequency can also be described as the reception time difference between the target cell and the reference cell. Two cells can also be described as more than one cell.

[0112] The report can be described as a measurement report or a report of measurement results, including at least the report of L1 measurement results. The report includes at least the report of L1 measurement results. The cell can be identified by the physical cell identifier (PCI), the frequency can be identified by the absolute radio frequency channel number (ARFCN), and the SSB can be identified by the SSB index.

[0113] Considering that the L1 measurement of neighboring cells of some terminals is limited by factors such as cost and complexity, it can usually only support scenarios with good synchronization, or the number of neighboring cells supported by L1 measurement is very limited. Based on this, in order to facilitate the network to screen cells or frequencies for L1 measurement and enable the terminal to use the limited L1 measurement capability for measurement of potential target cells, in one embodiment, the first information is used to indicate at least one of the following:

[0114] The terminal supports receiving time difference greater than CP;

[0115] The terminal does not support receiving time difference greater than CP;

[0116] The terminal supports receiving time difference less than or equal to CP;

[0117] The terminal supports simultaneous measurement of asynchronous cells;

[0118] The terminal does not support simultaneous measurement of asynchronous cells;

[0119] The terminal supports simultaneous L1 measurement of cells with a reception time difference greater than CP;

[0120] The terminal does not support simultaneous L1 measurement of cells whose reception time difference is greater than the CP.

[0121] Whether a terminal supports reception time differences greater than the CP, supports simultaneous measurement of asynchronous cells, and supports simultaneous L1 measurement of cells with reception time differences greater than the CP depends on the terminal's implementation algorithm and processing capabilities. Different terminals perform different L1 measurement methods, which can affect the performance of the L1 measurement supported by the terminal, such as the number of cells measured, measurement latency, scheduling opportunities (scheduling opportunities can also be described as scheduling idle time), and measurement restrictions. If a terminal supports reception time differences greater than the CP, it can be assumed that the terminal supports at least two Fast Fourier Transforms (FFTs) and can simultaneously measure at least two cells, eliminating the need to filter L1 measurements through L3 measurements. If a terminal does not support reception time differences greater than the CP (or is described as supporting reception time differences no greater than the CP), it can be assumed that the terminal only has one FFT and can only measure one cell at a time. Measurements of multiple cells must be performed serially, resulting in significant measurement latency. The receiving time difference information is reported to the network, which can assist the network in determining the measurement delay of the terminal and how to perform data scheduling, etc.; the receiving time difference information includes at least one of the following: the terminal supports a receiving time difference greater than CP, the terminal does not support a receiving time difference greater than CP, the terminal supports a receiving time difference less than or equal to CP, the terminal supports simultaneous L1 measurement of cells with a receiving time difference greater than CP, and the terminal does not support simultaneous L1 measurement of cells with a receiving time difference greater than CP.

[0122] The terminal supports a reception time difference greater than the CP, which can also be described as the terminal supports measuring a cell whose reception time difference is greater than the CP.

[0123] The simultaneous measurement of asynchronous cells can also be described as the simultaneous measurement of asynchronous cells at the same frequency. If the terminal supports the simultaneous measurement of asynchronous cells, the measurement can be completed faster and the measurement delay can be reduced compared to not supporting the simultaneous measurement of asynchronous cells.

[0124] The terminal supports simultaneous L1 measurement of cells whose reception time difference is greater than the CP. It can also be described as the terminal supporting simultaneous L1 measurement of cells whose reception time difference is greater than the CP, or as the terminal supporting simultaneous L1 measurement of cells when the reception time difference between the cells is greater than the CP length, or as the terminal supporting simultaneous L1 measurement of cells when the reception time difference between the cells is greater than the CP.

[0125] It should be noted that the reception time difference is related to at least one of the following: cell synchronization status (whether the cell is a synchronous cell), transmission delay from the cell to the terminal, or transmission delay difference.

[0126] To facilitate the network side in screening cells or frequencies for L1 measurement, so that the terminal can use limited L1 measurement capabilities for measuring potential target cells, in one embodiment, the first information is used to indicate at least one of the following:

[0127] Perform L1 measurement on N cells whose reception time difference is greater than CP at the same time, where N is an integer greater than 1;

[0128] L1 measurement is performed on the same symbol for N cells whose reception time difference is greater than CP, where N is an integer greater than 1.

[0129] Simultaneous L1 measurement of N cells with a reception time difference greater than CP can also be described as: supporting simultaneous L1 measurement of more than one cell with a reception time difference greater than CP, or as supporting simultaneous L1 measurement of more than one cell when the reception time difference between the cells is greater than the CP length, or as supporting simultaneous L1 measurement of more than one cell when the reception time difference between the cells is greater than the CP, or as supporting simultaneous L1 measurement of more than one cell when the reception time difference between the cells is greater than the CP length, or as supporting simultaneous L1 measurement of more than one cell by the terminal when the reception time difference between the cells is greater than the CP length, or as supporting simultaneous L1 measurement of more than one cell by the terminal when the reception time difference between the cells is greater than the CP.

[0130] To facilitate the network side in screening cells or frequencies for L1 measurement, in one embodiment, the second information includes at least one of the following:

[0131] The maximum number of cells measured;

[0132] The maximum number of frequency points to be measured;

[0133] The maximum number of cells reported;

[0134] The maximum number of beams reported;

[0135] The maximum value of the product of the number of reported cells and the number of beams;

[0136] the number of cells measured;

[0137] The number of measured frequencies;

[0138] The number of reported cells;

[0139] Number of beams reported.

[0140] Here, the terminal may report measurement capabilities and / or reporting capabilities to the network. The measurement capabilities may include at least one of the following: the maximum number of measured cells, the maximum number of measured frequencies, the number of measured cells, and the number of measured frequencies. The reporting capabilities may include at least one of the following: the maximum number of reported cells, the maximum number of reported beams, the maximum product of the number of reported cells and the number of beams, the number of reported cells, and the number of reported beams.

[0141] The maximum number of measured cells can be described as the maximum number of measured cells, or as the maximum number of cells measured for Layer 1 (L1). Furthermore, the maximum number of measured cells can also be understood as the number of cells supported by the terminal for L1 measurement, or represented by the maximum number of cells supported by the terminal for L1 measurement; because the terminal processing capability is limited and L1 measurements of a large number of cells cannot be performed, this information (the maximum number of measured cells) can be used to inform the network of the number of cells supported by the terminal for Layer 1 measurement. The number of cells configured by the network cannot exceed the maximum number of measured cells. The maximum number of measured cells can also be described as: the maximum number of candidate cells configured by RRC for L1-RSRP measurement.

[0142] The maximum number of measured frequencies can be described as the maximum number of measured frequencies, the maximum number of L1 measurement frequencies, or the maximum number of frequencies supported by the terminal for L1 measurement. Because terminals have limited processing capabilities and cannot perform L1 measurements on a large number of frequencies, this information (the maximum number of measured frequencies) notifies the network of the number of frequencies supported by the terminal for Layer 1 measurement. The number of frequencies configured by the network cannot exceed this value. The maximum number of measured frequencies can also be described as the maximum number of frequencies configured by RRC for L1-RSRP measurement.

[0143] The maximum number of reported cells can be described as the maximum number of reported cells supported, or as the maximum number of cells supported in one report. When the terminal reports the measurement results of L1 measurement, the maximum number of reported cells can be understood as: the maximum number of cells supported by the terminal for L1 reporting. For example, if the maximum value of the reported number of cells is M, it can be understood that the number of cells reported by the terminal for L1 measurement does not exceed M. Due to resource and signaling overhead limitations, the terminal does not necessarily need to report all the cell results of the measured cells. For example, if P cells are measured, the terminal will only report the results of M cells at most, M≤P. This information (the maximum number of reported cells) can assist the network in knowing the number of cells that the terminal can report, and then perform corresponding resource configuration.

[0144] The maximum value of the reported number of beams can be described as the maximum value of the number of beams supported for reporting, or as the maximum value of the number of beams supported in one report. The maximum value of the reported number of beams includes at least the maximum value of the reported number of beams for each cell and the maximum value of the reported number of beams for M cells. The terminal reports the measurement results of the L1 measurement, and the maximum value of the reported number of beams can be understood as: the maximum number of beams supported by the terminal for L1 reporting. For example, if the value of the maximum number of reported beams is L, it can be understood that the number of beams reported by the terminal for L1 measurement does not exceed L. Due to resource and signaling overhead limitations, the terminal does not necessarily need to report all the L1-RSRPs of the measured beams. This information (the maximum value of the reported number of beams) can assist the network in knowing the number of cells that the terminal can report, and then perform corresponding resource configuration.

[0145] The maximum value of the product of the reported number of cells and the number of beams is not necessarily the product of the "maximum value of the reported number of cells" and the "maximum value of the reported number of beams", and may be smaller than the product of the two.

[0146] The number of cells measured can be described as the number of cells for L1-RSRP measurement, or the number of neighboring cells for L1-RSRP measurement. The number of cells measured includes at least one of the number of cells with the same frequency and the number of cells with different frequencies.

[0147] To facilitate the network in screening cells or frequencies for L1 measurement, in one embodiment, the second information includes at least one of the following:

[0148] RSRP;

[0149] SSB index;

[0150] CSI-RS index;

[0151] Cell ID.

[0152] Here, the measurement report or measurement result reported by the terminal to the network may include at least one of the following: RSRP, SSB index, CSI-RS index, and cell identifier.

[0153] RSRP includes absolute RSRP and / or differential RSRP. Absolute RSRP is generally the highest RSRP. Differential RSRP is the difference between the RSRP of other beams and the highest RSRP. This solution can reduce the number of bits required for information reporting and reduce signaling overhead.

[0154] The SSB index can be described as a resource indicator (SSBRI, SS / PBCH Block Resource Indicator) or as an SSB number. Specifically, the SSB number can be the number of a total of K beams in M ​​cells.

[0155] The cell identifier may be a PCI.

[0156] In one embodiment, performing L1 measurement includes at least one of the following:

[0157] Perform L3 measurements;

[0158] Perform L3 reporting;

[0159] Report L3 measurement results.

[0160] Here, to address the mismatch between the mobility multi-frequency / cell measurement requirements and the terminal's L1 measurement capabilities, L3 measurements are used to filter subsequent L1 measurements, reducing the targets for L1 measurements (targets can be described as measurement targets). The targets include the number of cells, frequencies, and beams, making the L1 measurements more focused and using the terminal's limited measurement capabilities for the measurement of potential target cells. The benefits of this solution are: the network can configure multiple candidate cells, but the terminal can first perform L3 measurements. After screening based on the L3 results (either based on the terminal's autonomous determination or based on network instructions), the terminal further converges on potential candidate targets for L1 measurements. L3 measurements can also be described as Radio Resource Management (RRM) measurements, or mobility measurements, or as measurements of measurement targets or measurement objects (MOs). MOs can also be described as frequencies.

[0161] It should be noted that the module performing L3 measurements in a terminal is typically independent of the demodulation module. L3 measurements of neighboring cells are not subject to strict timing synchronization constraints and can also support L3 measurements of multiple cells. The module performing L1 measurements in a terminal can be integrated into the demodulation module. The L3 measurement results can include at least one of the Reference Signal Receiving Quality (RSRQ), RSRP, and SINR of the measurement target or target (cell, frequency, beam).

[0162] When the terminal performs L3 measurement of mobility triggered by L1 and obtains L3 measurement results, or when the terminal performs L3 reporting and / or reports L3 measurement results, the terminal can autonomously determine the cell or frequency for performing L1 measurement based on the L3 measurement results. Based on this, in one embodiment, performing L1 measurement includes at least one of the following:

[0163] Perform L1 measurement on cells or frequencies where the L3 measurement result is greater than or equal to the first threshold;

[0164] L1 measurement is performed on cells or frequencies where the L3 signal quality of the neighboring cell is at least a second threshold higher than the signal quality of the serving cell.

[0165] Here, the terminal can determine, based on the L3 measurement result, the cell or frequency whose L3 measurement result is greater than or equal to the first threshold, and perform L1 measurement on the cell or frequency whose L3 measurement result is greater than or equal to the first threshold. For the cell or frequency whose L3 measurement result is less than the first threshold, the terminal does not perform L1 measurement. The cell can be described as a neighboring cell, a co-frequency neighboring cell, a different-frequency neighboring cell, or as a candidate cell for L1-triggered mobility, where the candidate cell is a cell other than the serving cell. The frequency can be described as a frequency of a co-frequency neighboring cell, a frequency of a different-frequency neighboring cell, or as a candidate frequency for L1-triggered mobility, where the candidate frequency is a frequency other than the serving cell.

[0166] The terminal may also determine, based on the L3 measurement results, cells or frequencies where the L3 signal quality of the neighboring cell is at least higher (high can be described as higher or more) than the signal quality of the serving cell by a second threshold, and perform L1 measurement on cells or frequencies where the L3 signal quality of the neighboring cell is at least higher than the signal quality of the serving cell by the second threshold. For cells where the L3 signal quality of the neighboring cell is lower than the signal quality of the serving cell by the second threshold, the terminal does not perform L1 measurement.

[0167] In order to successfully perform L1-RSRP measurement and minimize data packet loss during the L1-RSRP measurement to improve data transmission reliability, in one embodiment, the method further includes at least one of the following:

[0168] Not receiving PDCCH and / or PDSCH and / or CSI-RS for tracking and / or CSI-RS for CQI on SSBs configured for L1-RSRP measurement;

[0169] Do not transmit PUSCH and / or PUCCH and / or SRS on SSBs configured for L1-RSRP measurement;

[0170] Not receiving the PDCCH and / or PDSCH and / or CSI-RS for tracking and / or CSI-RS for CQI on a symbol preceding the SSB configured for L1-RSRP measurement;

[0171] Do not transmit PUSCH and / or PUCCH and / or SRS in the symbol preceding the SSB configured for L1-RSRP measurement;

[0172] Not receiving the PDCCH and / or PDSCH and / or CSI-RS for tracking and / or CSI-RS for CQI on a symbol following the SSB configured for L1-RSRP measurement;

[0173] The PUSCH and / or PUCCH and / or SRS are not transmitted on a symbol following the SSB configured for L1-RSRP measurement.

[0174] Here, in the prior art, the terminal only performs L1-RSRP measurement on the serving cell, which does not affect data scheduling. Data scheduling includes at least one of the following: PDSCH reception, PDCCH reception, CSI-RS reception, PUCCH transmission, PUSCH transmission, and SRS transmission. However, LTM L1-RSRP measures L1-RSRP on neighboring cells, which include co-frequency neighboring cells and inter-frequency neighboring cells. Since different cells arrive at the terminal at different times and have different beam directions, data scheduling of the serving cell may not be performed when performing L1-RSRP measurement of neighboring cells. This embodiment specifies the locations where the terminal can not transmit or receive data, and also assists the network in determining the locations where data scheduling is not performed.

[0175] The SSB configured for L1-RSRP measurement may be described as an SSB configured for L1-RSRP measurement. The L1-RSRP measurement may also be described as an LTM L1-RSRP measurement.

[0176] The symbol can be described as an Orthogonal Frequency Division Multiplexing (OFDM) symbol.

[0177] Receiving PDCCH and / or PDSCH and / or CSI-RS for tracking and / or CSI-RS for CQI can be understood as receiving at least one of PDCCH, PDSCH, CSI-RS for tracking, and CSI-RS for CQI.

[0178] Sending PUSCH and / or PUCCH and / or SRS may be understood as sending at least one of PUSCH, PUCCH and SRS.

[0179] After the terminal reports the L3 measurement result related to L1 mobility to the network, the network device also indicates to the terminal the cell, frequency or SSB for performing L1 measurement. Based on this, in one embodiment, the method further includes:

[0180] Receive third information sent by the network, where the third information includes at least one of a cell identifier, a frequency point, and a synchronization signal block SSB for performing L1 measurement.

[0181] Here, the terminal may receive the third information sent by the network before performing L1 measurement.

[0182] As an implementation method, the network can select the N cells / frequencies / beams with the best RSRP / SINR / RSRQ based on the L3 measurement results reported by the terminal, and configure them for the terminal to perform L1 measurement for mobility. As an implementation method, in addition to referring to the L3 measurement results reported by the terminal, the network can also consider factors such as capacity and load to determine the M cells / frequencies / beams to configure for the terminal for L1 measurement. In other words, if a cell / frequency / beam has good channel conditions but a high corresponding load, the network may not select this cell / frequency / beam for the terminal to perform L1 measurement.

[0183] In the disclosed embodiment, the network directly indicates to the terminal the cell identifier and / or frequency and / or SSB for L1 measurement based on the L3 measurement result. The terminal does not need to filter the cell, frequency and SSB for L1 measurement based on the L3 measurement result, which can reduce the data processing amount of the terminal.

[0184] In one embodiment, the method further comprises:

[0185] Receive fourth information sent by the network, where the fourth information includes at least one of the following:

[0186] The correspondence between SSB index and cell identifier;

[0187] The correspondence between CSI-RS index and cell identifier.

[0188] Here, the terminal may receive the fourth information sent by the network before performing L1 measurement.

[0189] The correspondence between the SSB index and the cell identifier can also be described as a mapping between the SSB index and the cell identifier, or the correspondence between the SSB and the cell identifier, or the association between the SSB index and the cell identifier. The cell identifier can be described as the physical cell identifier of the cell configured as the LTM candidate. The SSB index is used to indicate the SSB resource from the LTM candidate cell. The SSB can also be described as the SS / PBCH block. The correspondence between the SSB index and the cell identifier includes: the cell identifier corresponds to or is associated with a first index (or is described as a first identifier) ​​(for example, the first index can be a number 1, 2, 3, ..., and so on. The first index corresponding to or associated with cell identifier_3 is 1, the first index corresponding to or associated with cell identifier_8 is 2, ..., and so on), and the first index or first identifier corresponds to or is associated with an SSB index (for example, the first value in the first index list (for example, the first value is 1) corresponds to the first value in the SSB resource list (for example, SSB index_1); the second value in the first index list (for example, the second value is 2) corresponds to the second value in the SSB resource list (for example, SSB index 3); ..., and so on). This method realizes the correspondence or association between the SSB index and the cell identifier (for example, taking the above example, the association between cell identifier_3 and SSB index_1 is realized, and the association between cell identifier_8 and SSB index_3 is realized). This method can reduce the signaling overhead while realizing the correspondence between the SSB index and the cell identifier (because the cell identifier or description is a physical cell identifier, it occupies more signaling overhead than a simple digital index). Specifically, the network is configured with M cells (the PCI of different cells is different), and each cell corresponds to P beams. Then the network uniformly numbers the total number of M×P SSBs, for example, using SSBRI to identify the SSB.

[0190] Table 1 shows an example of a mapping relationship between SSB and SSBRI of PCI1.

[0191] Table 1

[0192] Table 2 shows an example of the mapping relationship between SSB and SSBRI of PCI2.

[0193] Table 2

[0194] It should be noted that when the terminal obtains the fourth information, the corresponding cell identifier may not be reported when the terminal subsequently reports the measurement result, which can reduce the reporting overhead of the terminal. The terminal can know which beam of which cell the SSB (or beam) belongs to based on the SSBRI. The RSRP corresponding to the SSBRI is the measurement result of the corresponding beam of the corresponding cell.

[0195] Since L3 measurements of L1-triggered mobility and L3 measurements for handover will compete for measurement resources, in order to facilitate the network to know whether the terminal supports the use of L3 measurement results in L1 reporting, so that the network can tend to instruct the terminal's behavior according to actual needs, in one embodiment, the method further includes:

[0196] Sending fifth information to the network, where the fifth information is used to indicate at least one of the following:

[0197] Support for using L3 measurement results in L1 reporting;

[0198] The use of L3 measurement results in L1 reporting is not supported.

[0199] Here, the terminal may send the fifth information to the network before performing L1 measurement.

[0200] L1 reporting can be described as L1 measurement reporting. If the fifth information indicates that the terminal supports the use of L3 measurement results in L1 reporting, the terminal may prioritize L3 measurements for L1-triggered mobility. If the fifth information indicates that the terminal does not support the use of L3 measurement results in L1 reporting, the terminal prioritizes L3 measurements for handover. Supporting the use of L3 measurement results in L1 reporting can be understood as reporting L3 measurement results in L1 measurement reporting.

[0201] The number of frequencies, cells, or beams supported by the terminal for L3 measurement of handover far exceeds the number of frequencies, cells, or beams for L3 measurement of L1-triggered mobility (possibly 1 or 2). Taking frequency as an example, the number of frequencies supported by the terminal for L3 measurement of handover is at least 7, and the number of frequencies supported by the terminal for L3 measurement of L1-triggered mobility is 1 or 2. Since the L3 measurement of L1-triggered mobility and the L3 measurement for handover will compete for measurement resources, the network can tend to instruct the behavior of the terminal based on the fifth information. For example, when the mobility demand is high (needs to be completed quickly), the network can instruct the terminal to prioritize completing the L3 measurement of L1-triggered mobility. When the robustness requirement is high, the network can instruct the terminal to prioritize completing the L3 measurement for handover.

[0202] In some embodiments, the method further comprises:

[0203] Sixth information sent by the network is received, where the sixth information is used to indicate that the measurement target is used for L1 measurement.

[0204] Here, the terminal may receive sixth information sent by the network before performing L1 measurements. The sixth information may be issued based on the fifth information or before the terminal performs L1 measurements. The fifth information may be reported to the network before the terminal performs L1 measurements. The sixth information may also be used to indicate that the measurement target is for L3 measurements of L1-triggered mobility. It should be noted that the sixth information may also include the priority of L3 measurements for handovers and the priority of L3 measurements for L1-triggered mobility.

[0205] The measurement target can be described as a measurement object. The measurement target includes at least one of a cell identifier, a frequency point, and an SSB.

[0206] When the sixth information is received, the terminal performs L1 measurement based on the first information. Based on this, in one embodiment, the method further includes:

[0207] Prioritize measurement of measurement targets used for L1 measurement.

[0208] Here, prioritizing measurement of measurement targets for L1 measurement can be understood as: when measurement targets include measurement targets for L3 measurement and measurement targets for L1 measurement, prioritizing measurement of measurement targets for L1 measurement. In other words, the priority of measurement targets for L1 measurement is higher than the priority of measurement targets for L3 measurement. A measurement target for L1 measurement can be understood as a measurement target for L3 measurement of L1-triggered mobility, or a measurement target that supports both L1 and L3 measurements. A measurement target for L3 measurement can be understood as a measurement target for L3 measurement used for handover, or a measurement target that supports L3 measurement but not L1 measurement.

[0209] For example, when the network is configured with multiple measurement targets, a measurement target for L1 measurement can be determined from the measurement targets configured in the network, and L3 measurement of the measurement target for L1 measurement can be performed preferentially to obtain an L3 measurement result, thereby reducing the need for subsequent L1 measurement based on the L3 measurement result.

[0210] Correspondingly, an embodiment of the present disclosure further provides a measurement method, which is applied to a network. The network can be described as a network device, a network-side device, and a base station. As shown in FIG2 , the method includes:

[0211] Step 201: Receive first information and / or second information sent by a terminal.

[0212] The first information is related to the reception time difference, and the second information is related to reporting and / or measurement.

[0213] The first information may be used to indicate at least one of the following:

[0214] The terminal supports receiving time difference greater than CP;

[0215] The terminal does not support receiving time difference greater than CP;

[0216] The terminal supports receiving time difference less than or equal to CP;

[0217] The terminal supports simultaneous measurement of asynchronous cells;

[0218] The terminal does not support simultaneous measurement of asynchronous cells;

[0219] The terminal supports simultaneous L1 measurement of cells with a reception time difference greater than CP;

[0220] The terminal does not support simultaneous L1 measurement of cells whose reception time difference is greater than the CP.

[0221] The first information may be used to indicate at least one of the following:

[0222] Perform L1 measurement on N cells whose reception time difference is greater than CP at the same time, where N is an integer greater than 1;

[0223] L1 measurement is performed on the same symbol for N cells whose reception time difference is greater than CP, where N is an integer greater than 1.

[0224] Here, when the terminal supports a reception time difference greater than the CP, the network may not send the third information and / or the sixth information to the terminal, that is, the terminal does not need to filter the L1 measurement through the L3 measurement. When the terminal does not support a reception time difference greater than the CP, or the terminal supports a reception time difference less than or equal to the CP, or the terminal does not support simultaneous measurement of asynchronous cells, the network needs to send the third information and / or the sixth information to the terminal, that is, the terminal needs to filter the L1 measurement through the L3 measurement.

[0225] The second information may include at least one of the following:

[0226] The maximum number of cells measured;

[0227] The maximum number of frequency points to be measured;

[0228] The maximum number of cells reported;

[0229] The maximum number of beams reported;

[0230] The maximum value of the product of the number of reported cells and the number of beams;

[0231] the number of cells measured;

[0232] The number of measured frequencies;

[0233] The number of reported cells;

[0234] Number of beams reported.

[0235] The second information may include at least one of the following:

[0236] RSRP;

[0237] SSB index;

[0238] CSI-RS index;

[0239] Cell ID.

[0240] In one embodiment, the method further comprises:

[0241] Sending third information to the terminal, where the third information includes at least one of a cell identifier, a frequency point, and an SSB for performing L1 measurement.

[0242] Here, the network may send third information to the terminal before the terminal performs L1 measurement. For example, upon receiving the measurement results of L3 measurement of L1-triggered mobility reported by the terminal, the network may filter out measurement targets for which L1 measurement is ultimately required based on the L3 measurement results, and send the third information to the terminal to reduce the need for L1 measurement. The measurement target includes at least one of a cell identifier, a frequency, and an SSB.

[0243] In order to facilitate the terminal to learn the correspondence between the SSB and / or CSI-RS and the cell, thereby reducing the reporting overhead of the terminal, in one embodiment, the method further includes:

[0244] Sending fourth information to the terminal, where the fourth information includes at least one of the following:

[0245] The correspondence between SSB index and cell identifier;

[0246] The correspondence between CSI-RS index and cell identifier.

[0247] Here, the network may send the fourth information to the terminal before the terminal performs L1 measurement.

[0248] In order to facilitate the network to know whether the terminal supports the use of L3 measurement results in L1 reporting, so that the network can tend to instruct the terminal's behavior according to actual needs. Based on this, in one embodiment, the method further includes:

[0249] receiving fifth information sent by the terminal, where the fifth information is used to indicate at least one of the following:

[0250] Support for using L3 measurement results in L1 reporting;

[0251] The use of L3 measurement results in L1 reporting is not supported.

[0252] Here, the fifth information may be sent by the terminal before performing L1 measurement. The network may determine, based on the fifth information, whether the terminal supports using L3 measurement results in L1 reporting, and decide whether to instruct the terminal to filter L1 measurement requirements through L3 measurement. If the terminal supports using L3 measurement results in L1 reporting, the terminal supports filtering L1 measurement requirements through L3 measurement.

[0253] To facilitate the terminal to perform L3 measurement of L1-triggered mobility, thereby reducing the need for subsequent L1 measurement based on the L3 measurement result, in one embodiment, the method further includes:

[0254] Sending sixth information to the terminal, where the sixth information is used to indicate that the measurement target is used for L1 measurement.

[0255] Here, the network may send the sixth information to the terminal before the terminal performs L1 measurement.

Furthermore, the measurement device and the measurement method embodiments provided in the above embodiments are based on the same concept.

[0326] Based on the hardware implementation of the above program modules, and in order to implement the method on the terminal side of the embodiment of the present disclosure, the embodiment of the present disclosure further provides a terminal, as shown in FIG5 , where the terminal 500 includes:
