Description

1.1.1 Technical Field

[0002] The present application relates to the field of wireless communications, and in particular to a measurement method, device, terminal, and storage medium. 1.1.2 Background Technology

[0004] In related technologies, terminals perform mobility behaviors such as cell reselection and handover based on measurements of synchronization signal blocks (SSBs) or channel state information-reference signals (CSI-RSs). These measurements require specific specifications for terminal behavior, latency, and accuracy. For example, when measuring SSBs at a specific frequency, a terminal must meet certain measurement latency requirements.

[0005] In the carrier aggregation (CA) scenario, the measurement time required by the terminal for multiple carriers is related to the number of carriers. The more carriers there are, the longer the measurement time.

[0006] In high-speed rail scenarios, high-speed movement is very sensitive to measurement latency, so new measurement methods need to be introduced to meet the needs of high-speed movement. 1.1.3 Summary of the invention

[0162] The present application will be described in further detail below with reference to the accompanying drawings and embodiments.

[0163] In the CA scenario, the measurement time required by the terminal for multiple secondary carriers is related to the number of secondary carriers. The more secondary carriers there are, the longer the measurement time.

[0164] In related technologies, terminal measurements in Carrier Amplification (CA) scenarios are based on the measurement duration of a single carrier, simply multiplied by the number of secondary component carriers (SCCs). The greater the number of secondary carriers, the longer the measurement time. However, in high-speed train (HST) scenarios (where speeds meet certain thresholds, such as 350 km / h or 500 km / h), this approach cannot meet the mobility requirements of high-speed trains (HSTs), as high-speed mobility is highly sensitive to measurement latency. Therefore, new measurement methods are needed to improve terminal measurement performance, specifically targeting high-speed mobility.

[0165] Based on this, in various embodiments of the present application, the time domain position relationship of the reference signals between different carriers and the reference signal configuration of the auxiliary carrier (such as whether the measurement is a measurement requiring a measurement interval or a measurement not requiring a measurement interval) are utilized to regulate the measurement behavior of the terminal.

[0166] The embodiment of the present application provides a measurement method, which is applied to a terminal, such as Figure 1 As shown, the method includes:

[0167] Step 101: perform measurement based on a first factor; the first factor is associated with at least one of first information and second information; the first information represents the time domain position relationship of the reference signal of the carrier, that is, the first information represents the time domain position relationship of the reference signals of different carriers; the second information represents the number of carriers.

[0168] In practical applications, the reference signal may include at least one of the following:

[0169] SSB;

[0170] CSI-RS;

[0171] PRS.

[0172] The reference signal may also be referred to as a reference symbol.

[0173] The solution of the embodiments of the present application can be applied to CA, dual connectivity (DC), or multi-connectivity scenarios. DC scenarios include EN-DC, NE-DC, and NR-DC. In these scenarios, the carrier can include a primary carrier and / or a SCC. The SCC can also be described as a secondary cell (SCell), and the carrier can also be described as a cell.

[0174] The solution of the embodiment of the present application can also be applied to the measurement of at least one of the following systems:

[0175] Same frequency system;

[0176] Different frequency system;

[0177] Different system.

[0178] In these scenarios, the carrier can also be described as a measurement target (MO) or frequency point. When the carrier is described as a frequency point, the frequency point includes: same-frequency frequency point, different-frequency frequency point, different-system frequency point, and auxiliary carrier measurement frequency point.

[0179] Here, in actual application, the carrier may be configured through higher layer signaling such as radio resource control (RRC) signaling.

[0180] There are many possibilities for the time domain position relationship of the measurement reference signals, such as complete time domain overlap, partial time domain overlap, and no time domain overlap.

[0181] Therefore, the time domain position relationship of the reference signals of different carriers includes at least one of the following:

[0182] The time domains completely overlap;

[0183] The time domain partially overlaps;

[0184] The time domains do not overlap at all.

[0185] Here, in combination with different types of reference signals, the first factor satisfies at least one of the following:

[0186] Association with SMTC, specifically association with SMTC of different carriers, which can also be called association with the time domain position of SSB;

[0187] Correlation with the time domain position of the CSI-RS, specifically correlation with the time domain position of the CSI-RS of different carriers;

[0188] Correlation with the time domain position of SMTC and CSI-RS, specifically correlation with the time domain position of SMTC and CSI-RS of different carriers;

[0189] Correlation with the time domain position of the PRS, specifically correlation with the PRS of different carriers;

[0190] Correlation with the time domain positions of SMTC and PRS, specifically correlation with the time domain positions of SMTC and PRS of different carriers;

[0191] The time domain positions of the CSI-RS and PRS are associated with each other, specifically, the time domain positions of the CSI-RS and PRS of different carriers are associated with each other.

[0192] In the embodiment of the present application, SMTC may also be referred to as SSB.

[0193] In the high-speed rail scenario, it is necessary to reduce the measurement delay. Therefore, it is possible to consider parallel processing of carriers with non-overlapping time domain positions. In addition, the specific implementation of the terminal can be further considered.

[0194] Based on this, in one embodiment, when the first factor is associated with SMTC, the first factor includes at least one of the following:

[0195] The difference between the twelfth value and the number of carriers that do not overlap with the SMTC;

[0196] The difference between the thirteenth value and the number of carriers whose SMTC time domain interval is greater than and / or equal to the first threshold;

[0197] At least two of the following numbers or the sum of at least two of the following numbers: the number of SMTC completely overlapping carriers; the number of SMTC partially overlapping carriers; the number of carriers whose SMTC time domain interval is less than and / or equal to the second threshold; here, the first factor may also only include the number of carriers whose SMTC time domain interval is less than the second threshold and the number of carriers whose SMTC time domain interval is equal to the second threshold, or the first factor may only include the sum of the number of carriers whose SMTC time domain interval is less than the second threshold and the number of carriers whose SMTC time domain interval is equal to the second threshold.

[0198] Here, in actual application, the twelfth value and the thirteenth value refer to the total number of carriers. Here, the total number of carriers may include the sum of at least two of the number of carriers that do not overlap with SMTC, the number of carriers that overlap with SMTC, and the number of carriers that partially overlap with SMTC.

[0199] Here, the number of carriers may be the number of carriers configured by the network. The carriers may include at least one of the following:

[0200] Carrier based on SSB measurements;

[0201] Carrier based on CSI-RS measurements;

[0202] Carrier based on PRS measurements.

[0203] The first threshold and the second threshold can be set as needed.

[0204] The network side may indicate the first threshold and / or the second threshold to the terminal through signaling, such as RRC signaling, a medium access control (MAC) control element (CE) or downlink control information (DCI), or may pre-define the first threshold and / or the second threshold, thereby pre-setting the first threshold and / or the second threshold in the terminal.

[0205] In one embodiment, when the first factor is associated with the time domain position of the CSI-RS, the first factor includes at least one of the following:

[0206] The difference between the fourteenth value and the number of carriers where the CSI-RS does not overlap;

[0207] The difference between the fifteenth value and the number of carriers whose CSI-RS time domain interval is greater than and / or equal to the third threshold;

[0209] Here, in actual application, the fourteenth value and the fifteenth value refer to the total number of carriers. Here, the total number of carriers may include at least two numbers of the number of carriers that do not overlap with the CSI-RS, the number of carriers that overlap with the CSI-RS, and the number of carriers that partially overlap with the CSI-RS.

[0210] Here, the number of carriers may be the number of carriers configured by the network. The carriers may include at least one of the following:

[0211] Carrier based on SSB measurements;

[0212] Carrier based on CSI-RS measurements;

[0213] Carrier based on PRS measurements.

[0214] The third threshold and the fourth threshold can be set as needed.

[0215] The network side may indicate the third threshold and / or fourth threshold to the terminal through signaling, such as RRC signaling, MAC CE or DCI, or may predefine the third threshold and / or fourth threshold, thereby pre-setting the third threshold and / or fourth threshold in the terminal.

[0216] In one embodiment, when the first factor is associated with the time domain position of the SMTC and the CSI-RS, the first factor includes at least one of the following:

[0217] The difference between the sixteenth value and the number of non-overlapping carriers; the non-overlapping carriers include carriers whose SMTC and CSI-RS time domains do not overlap;

[0218] The difference between the total number of CA secondary carriers and the number of secondary carriers whose time domain interval is greater than and / or equal to the fifth threshold; the time domain interval includes the time domain interval of SMTC and CSI-RS;

[0220] Here, in actual application, the sixteenth value refers to the total number of carriers. Here, the total number of carriers may include at least two numbers of the number of carriers that completely overlap with the time domain of SMTC and CSI-RS, the number of carriers that completely do not overlap with the time domain of SMTC and CSI-RS, and the number of carriers that partially overlap with the time domain of SMTC and CSI-RS.

[0226] The network side may indicate the fifth threshold and / or sixth threshold to the terminal through signaling, such as RRC signaling, MAC CE or DCI, or may predefine the fifth threshold and / or sixth threshold, thereby presetting the fifth threshold and / or sixth threshold in the terminal.

[0227] The carrier in which SMTC and CSI-RS do not overlap in time domain refers to the carrier in which SMTC and CSI-RS do not overlap in time domain; accordingly, the time domain interval between SMTC and CSI-RS refers to the time domain interval between SMTC and CSI-RS; the time domain complete overlap between SMTC and CSI-RS refers to the carrier in which the time domain between SMTC and CSI-RS completely overlaps; the carrier in which SMTC and CSI-RS partially overlap in time domain refers to the carrier in which the time domain between SMTC and CSI-RS partially overlaps.

[0228] In one embodiment, when the first factor is associated with the time domain position of the PRS, the first factor includes at least one of the following:

[0229] The difference between the seventeenth value and the number of carriers where the PRS does not overlap;

[0232] Here, in actual application, the seventeenth value and the eighteenth value refer to the total number of carriers. Here, the total number of carriers may include the sum of at least two of the number of carriers that completely overlap with the PRS time domain, the number of carriers that completely do not overlap with the PRS time domain, and the number of carriers that partially overlap with the PRS time domain.

[0233] Here, the number of carriers may be the number of carriers configured by the network. The carriers may include at least one of the following:

[0234] Carrier based on SSB measurements;

[0236] Carrier based on PRS measurements.

[0237] The thirteenth threshold and the fourteenth threshold can be set as needed.

[0238] The network side may indicate the thirteenth threshold and / or the fourteenth threshold to the terminal through signaling, such as RRC signaling, MAC CE or DCI, or may predefine the thirteenth threshold and / or the fourteenth threshold, thereby pre-setting the thirteenth threshold and / or the fourteenth threshold in the terminal.

[0239] In one embodiment, when the first factor is associated with the time domain position of the SMTC and the PRS, the first factor includes at least one of the following:

[0240] The difference between the nineteenth value and the number of non-overlapping carriers; the non-overlapping carriers include carriers whose SMTC and PRS time domains do not overlap;

[0241] The difference between the total number of CA secondary carriers and the number of secondary carriers whose time domain interval is greater than and / or equal to the fifteenth threshold; the time domain interval includes the time domain interval of SMTC and PRS;

[0242] At least two of the following numbers or the sum of at least two of the following numbers: the number of carriers with complete time domain overlap of SMTC and PRS, the number of carriers with partial time domain overlap of SMTC and PRS, the number of carriers with a time domain interval of SMTC and PRS less than and / or equal to the sixteenth threshold; here, the first factor may also only include the sum of the number of carriers with a time domain interval of MTC and PRS less than the sixteenth threshold and the number of carriers with a time domain interval of MTC and PRS equal to the sixteenth threshold, or the first factor may only include the number of carriers with a time domain interval of MTC and PRS less than the sixteenth threshold and the number of carriers with a time domain interval of MTC and PRS equal to the sixteenth threshold.

[0243] Here, in actual application, the nineteenth value refers to the total number of carriers. Here, the total number of carriers may include the sum of at least two of the number of carriers that completely overlap with the time domain of SMTC and PRS, the number of carriers that completely do not overlap with the time domain of SMTC and PRS, and the number of carriers that partially overlap with the time domain of SMTC and PRS.

[0244] Here, the number of carriers may be the number of carriers configured by the network. The carriers may include at least one of the following:

[0245] Carrier based on SSB measurements;

[0246] Carrier based on CSI-RS measurements;

[0247] Carrier based on PRS measurements.

[0248] The fifteenth threshold and the sixteenth threshold can be set as needed.

[0249] The network side may indicate the fifteenth threshold and / or the sixteenth threshold to the terminal through signaling, such as RRC signaling, MAC CE or DCI, or may predefine the fifteenth threshold and / or the sixteenth threshold, thereby pre-setting the fifteenth threshold and / or the sixteenth threshold in the terminal.

[0250] The carrier in which SMTC and PRS do not overlap in time domain refers to the carrier in which SMTC and PRS do not overlap in time domain; accordingly, the time domain interval between SMTC and PRS refers to the time domain interval between SMTC and PRS; the time domain complete overlap between SMTC and PRS refers to the carrier in which the time domain between SMTC and PRS completely overlaps; the carrier in which SMTC and PRS partially overlap in time domain refers to the carrier in which the time domain between SMTC and PRS partially overlaps.

[0251] In one embodiment, when the first factor is associated with the time domain positions of the CSI-RS and the PRS, the first factor includes at least one of the following:

[0252] The difference between the twentieth value and the number of non-overlapping carriers; the non-overlapping carriers include carriers whose CSI-RS and PRS time domains do not overlap;

[0253] The difference between the total number of CA secondary carriers and the number of secondary carriers whose time domain interval is greater than and / or equal to the seventeenth threshold; the time domain interval includes the time domain interval of CSI-RS and PRS;

[0254] At least two of the following numbers or the sum of at least two of the following numbers: the number of carriers where CSI-RS and PRS completely overlap in time domain, the number of carriers where CSI-RS and PRS partially overlap in time domain, and the number of carriers where the time domain interval between CSI-RS and PRS is less than and / or equal to the eighteenth threshold; here, the first factor may also include only the sum of the number of carriers where the time domain interval between CSI-RS and PRS is less than the eighteenth threshold and the number of carriers where the time domain interval between CSI-RS and PRS is equal to the eighteenth threshold, or the first factor may include only the number of carriers where the time domain interval between CSI-RS and PRS is less than the eighteenth threshold and the number of carriers where the time domain interval between CSI-RS and PRS is equal to the eighteenth threshold.

[0255] Here, in actual application, the twentieth value refers to the total number of carriers, where the total number of carriers may include the sum of at least two of the number of carriers that completely overlap with the time domain of CSI-RS and PRS, the number of carriers that completely do not overlap with the time domain of CSI-RS and PRS, and the number of carriers that partially overlap with the time domain of CSI-RS and PRS.

[0256] Here, the number of carriers may be the number of carriers configured by the network. The carriers may include at least one of the following:

[0257] Carrier based on SSB measurements;

[0258] Carrier based on CSI-RS measurements;

[0259] Carrier based on PRS measurements.

[0260] The seventeenth threshold and the eighteenth threshold can be set as needed.

[0261] The network side may indicate the seventeenth threshold and / or the eighteenth threshold to the terminal through signaling, such as RRC signaling, MAC CE or DCI, or may predefine the seventeenth threshold and / or the eighteenth threshold, thereby pre-setting the seventeenth threshold and / or the eighteenth threshold in the terminal.

[0262] The carrier in which the CSI-RS and PRS do not overlap in time domain refers to the carrier in which the time domain between CSI-RS and PRS does not overlap; accordingly, the time domain interval between CSI-RS and PRS refers to the time domain interval between CSI-RS and PRS; the time domain of CSI-RS and PRS completely overlaps refers to the carrier in which the time domain between CSI-RS and PRS completely overlaps; the carrier in which the time domain of CSI-RS and PRS partially overlaps refers to the carrier in which the time domain between CSI-RS and PRS partially overlaps.

[0263] Here, considering that the same network can serve multiple scenarios simultaneously, different factors can be considered in different scenarios, resulting in different values ​​of the first factor. For example, different first factor values ​​are used for enhanced mobile broadband (eMBB) services, ultra-reliable and low-latency communication (URLLC) services, and massive machine type communication (mMTC) services. For example, different first factor values ​​are used for high-speed rail (i.e. high-speed) scenarios and non-high-speed rail (i.e. non-high-speed) scenarios.

[0264] In actual application, when measuring based on the first factor, the measurement behavior of the terminal may be defined as follows:

[0265] The measurement of multiple target carriers needs to be completed within a certain time, which is related to factors such as the measurement time of a single carrier and the first factor.

[0266] In actual application, the terminal needs to first determine the first factor and then perform measurement based on the first factor.

[0267] Based on this, in one embodiment, if Figure 1 As shown, the method may further include:

[0268] Step 100: Determine the first factor.

[0269] The terminal may determine the first factor based on time domain location information of measurement reference signals of different carriers. In other words, the terminal determines the first factor based on time domain location information of reference signals.

[0270] The terminal may also determine the first factor according to network information, for example, the network side indicates the first factor through signaling such as RRC signaling, MAC CE or DCI.

[0271] Here, when the terminal determines the first factor according to the time domain position information of the reference signals of different carriers, the first factor may be determined in the above manner.

[0272] Specifically, in one embodiment, when non-overlapping carriers exist among the carriers (i.e., carriers that do not overlap in the time domain), the first factor is determined to be a first value. In actual applications, when non-overlapping carriers exist among the carriers, the value of the first factor can be the first value, and the first value can be the difference included in the first factor. For example, assuming there are 9 carriers and the number of non-overlapping carriers is 4, in this case, according to the sum of the difference and / or number included in the first factor, the value of the first factor is 9-4=5.

[0273] In practical applications, when the above method is used to directly determine the value of the first factor, while it can improve measurement performance (i.e., reduce measurement latency), it may also increase the complexity of terminal measurement. Therefore, to balance measurement performance and terminal implementation complexity, the value of the first factor may not be the sum of the differences and / or numbers included in the above first factor.

[0274] Based on this, in one embodiment, when there is a carrier whose time domain interval is greater than or equal to a sixth threshold among the carriers, the first factor is determined to be the second value.

[0275] Among them, for the second value, it is different from the sum of the difference and / or number contained in the above-mentioned first factor in the same case, but a certain amplification is performed on this basis, which can also be understood as relaxation. For example, assuming that there are 9 carriers, the number of carriers with a time domain interval greater than and / or equal to the first threshold is 5, and among these 5 carriers, there is a carrier with a time domain interval greater than or equal to the sixth threshold. At this time, when the sum of the difference and / or number contained in the above-mentioned first factor is used, the value of the first factor can be obtained as 9-5=4, but considering the complexity of the terminal measurement implementation, that is, considering the implementation capability of the terminal, thereby reducing the complexity of the terminal implementation, the value of the first factor can be 5.

[0276] In actual application, the second value can be indicated by the network side (it can also be understood as being notified by the network side), for example, the network side indicates the second value to the terminal through RRC signaling, MAC CE or DCI, etc., or it can be pre-defined and thus pre-set in the terminal, or it can be determined by the terminal itself.

[0277] The sixth threshold may also be indicated by the network side, for example, the network side indicates the sixth threshold to the terminal through RRC signaling, MAC CE or DCI, that is, the terminal receives the sixth threshold, or it may be predefined and thus pre-set in the terminal.

[0278] In one embodiment, when non-overlapping carriers exist among the carriers and the number of non-overlapping carriers meets a seventh threshold, the first factor is determined to be a third value.

[0279] The third value differs from the use of the sum of the differences and / or numbers included in the first factor in the same scenario. Instead, it is amplified to some extent, which can also be understood as relaxation. For example, assuming there are 9 carriers, the number of non-overlapping carriers is 5, which is greater than 3 (i.e., the seventh threshold). In this case, using the sum of the differences and / or numbers included in the first factor, the value of the first factor can be 9-5=4. However, considering the complexity of terminal measurement implementation, i.e., considering the terminal's implementation capabilities, thereby reducing the complexity of terminal implementation, the value of the first factor can be 5.

[0280] In actual application, the third value can be indicated by the network side, for example, the network side indicates the third value to the terminal through signaling such as RRC signaling, MACCE or DCI, or it can be predefined and thus pre-set in the terminal, or it can be determined by the terminal itself.

[0281] The seventh threshold may also be indicated by the network side, for example, by the network side indicating the seventh threshold to the terminal through RRC signaling, MAC CE, or DCI, i.e., the terminal receives the seventh threshold. The seventh threshold may also be predefined and thus pre-set in the terminal. The seventh threshold may be in the form of an integer or a ratio, such as the ratio of the number of non-overlapping carriers to the total number of carriers.

[0282] In one embodiment, when there are carriers with a time domain interval greater than or equal to a sixth threshold, and the number of carriers with a time domain interval greater than or equal to the sixth threshold meets an eighth threshold, the first factor is determined to be a fourth value.

[0283] Among them, for the fourth value, unlike the use of the sum of the differences and / or numbers included in the above-mentioned first factor in the same situation, a certain amplification is performed on this basis, which can also be understood as relaxation. For example, assuming there are 9 carriers, the number of carriers with time domain intervals greater than and / or equal to the first threshold is 5, and among these 5 carriers, there are carriers with time domain intervals greater than or equal to the sixth threshold, the number is 3, which is greater than 2 (i.e., the eighth threshold). At this time, when the sum of the differences and / or numbers included in the above-mentioned first factor is used, the value of the first factor can be obtained as 9-5=4. However, considering the complexity of terminal measurement implementation, that is, considering the implementation capability of the terminal, thereby reducing the complexity of terminal implementation, the value of the first factor can be 6.

[0284] In actual application, the fourth value can be indicated by the network side, for example, the network side indicates the fourth value to the terminal through RRC signaling, MAC CE or DCI, etc., or it can be predefined and thus pre-set in the terminal, or it can be determined by the terminal itself.

[0285] The eighth threshold may also be indicated by the network side, for example, the network side indicates the eighth threshold to the terminal through RRC signaling, MAC CE, or DCI, that is, the terminal receives the eighth threshold, or may be predefined and thus pre-set in the terminal. The eighth threshold may be in the form of an integer or a ratio, such as the ratio of the number of carriers whose time domain interval is greater than or equal to the sixth threshold to the total number of carriers.

[0286] In one embodiment, when there are overlapping carriers among the carriers and the number of overlapping carriers meets a ninth threshold, the first factor is determined to be a fifth value.

[0287] Among them, the fifth value is different from the use of the sum of the differences and / or numbers included in the first factor in the same situation. Instead, it is amplified to a certain extent on this basis, which can also be understood as relaxation. For example, assuming there are 9 carriers, there are carriers with time domain overlap, and the number of overlapping carriers is 4, which is greater than 2 (i.e., the ninth threshold). At this time, when the sum of the differences and / or numbers included in the first factor is used, the value of the first factor can be 4. However, considering the complexity of terminal measurement implementation, that is, considering the terminal's implementation capabilities, thereby reducing the complexity of terminal implementation, the value of the first factor can be 6.

[0288] In actual application, the fifth value can be indicated by the network side, for example, the network side indicates the fifth value to the terminal through RRC signaling, MAC CE or DCI, etc., or it can be predefined and thus pre-set in the terminal, or it can be determined by the terminal itself.

[0289] The ninth threshold may also be indicated by the network side, for example, by the network side indicating the ninth threshold to the terminal through RRC signaling, MAC CE, or DCI, i.e., the terminal receives the ninth threshold. The ninth threshold may also be predefined and thus pre-set in the terminal. The ninth threshold may be in the form of an integer or a ratio, such as the ratio of the number of overlapping carriers to the total number of carriers.

[0290] In actual application, when the terminal determines the first factor based on the time domain position information of the measurement reference signals of different carriers, since it takes a certain amount of time for the terminal to process the reference signal, if the two reference signals are close to each other in the time domain, the terminal may not be able to process the second reference signal (the one that comes later in time based on the time sequence), and the measurement performance of both reference signals may not be guaranteed. Therefore, the network side can indicate the carriers that the terminal can measure simultaneously and / or which carriers do not overlap in the time domain, thereby ensuring the measurement performance of the terminal.

[0291] Based on this, in one embodiment, the method may further include:

[0292] receiving third information;

[0293] The first factor is determined using the third information.

[0294] The third information may include at least one of the following:

[0295] Time domain interval threshold of SMTC;

[0296] CSI-RS time domain interval threshold;

[0297] Time domain interval threshold of SMTC and CSI-RS;

[0298] Time domain interval threshold of PRS;

[0299] Time domain separation threshold of SMTC and PRS;

[0300] Time domain separation threshold of CSI-RS and PRS.

[0301] Specifically, the third information indicated by the network side is received. In actual application, the network side may indicate the third information to the terminal through RRC signaling, MAC CE or DCI.

[0302] The time domain interval threshold of the SMTC refers to the time domain interval threshold between SMTCs. When the time domain interval between two SMTCs is greater than or equal to the threshold, it can be considered that the two SMTCs are completely non-overlapping, or it can be understood that the terminal can independently process the two SMTCs, that is, measure the two SMTCs separately, that is, the terminal can measure the two SMTCs simultaneously.

[0303] The CSI-RS time domain interval threshold refers to the time domain interval threshold between CSI-RSs. When the time domain interval of two CSI-RSs is greater than or equal to the threshold, it can be considered that the two CSI-RSs are completely non-overlapping, or it can be understood that the terminal can independently process the two CSI-RSs, that is, measure the two CSI-RSs separately, that is, the terminal can measure the two CSI-RSs simultaneously.

[0304] The time domain interval threshold of the SMTC and CSI-RS refers to the time domain interval threshold between SMTC and CSI-RS. When the time domain interval between SMTC and CSI-RS is greater than or equal to the threshold, it can be considered that the two reference signals SMTC and CSI-RS are completely non-overlapping, or it can be understood that the terminal can independently process the two SMTC and CSI-RS, that is, measure SMTC and CSI-RS separately, and the terminal can measure the two SMTC and CSI-RS at the same time.

[0305] The time domain interval threshold of the PRS refers to the time domain interval threshold between the PRSs. When the time domain interval of two PRSs is greater than or equal to the threshold, it can be considered that the two PRSs are completely non-overlapping, or it can be understood that the terminal can independently process the two PRSs, that is, measure the two PRSs separately, that is, the terminal can measure the two PRSs simultaneously.

[0306] The time domain interval threshold of the SMTC and PRS refers to the time domain interval threshold between the SMTC and the PRS. When the time domain interval between the SMTC and the PRS is greater than or equal to the threshold, it can be considered that the two reference signals SMTC and PRS are completely non-overlapping, or it can be understood that the terminal can independently process the two SMTC and PRS, that is, measure the SMTC and PRS separately, and the terminal can measure the two SMTC and PRS simultaneously.

[0307] The time domain interval threshold of the CSI-RS and PRS refers to the time domain interval threshold between the CSI-RS and the PRS. When the time domain interval between the CSI-RS and the PRS is greater than or equal to the threshold, it can be considered that the two reference signals of the CSI-RS and the PRS are completely non-overlapping, or it can be understood that the terminal can independently process the two CSI-RS and PRS, that is, measure the CSI-RS and PRS separately, and the terminal can measure the two CSI-RS and PRS simultaneously.

[0308] The value of the above time domain interval threshold may be different according to different implementations of the terminal.

[0309] In actual application, the network side may send measurement delay related information to the terminal. The measurement delay related information may be understood as the time within which the network expects the terminal to complete the measurement of N frequency points, where N is an integer greater than or equal to 1.

[0310] Based on this, in one embodiment, the method may further include:

[0311] Receive delay measurement information sent by the network side;

[0312] The received measurement delay related information is used to determine the measurement duration for completing the measurement, that is, the measurement duration for completing the measurement expected by the network side.

[0313] The network side may broadcast the delay measurement related information, or may send the delay measurement related information to the terminal through RRC signaling.

[0314] After the terminal learns the network's expected measurement duration, the network will not schedule the terminal while the terminal is performing the measurement, allowing the network to schedule the terminal in a timely manner. In other words, when the terminal and the network share the same understanding of the measurement duration, they can assist the network in scheduling.

[0315] The delay measurement related information may include a measurement duration (also referred to as a delay measurement duration, which is not limited in this embodiment of the application), that is, the network side indicates the measurement duration. The measurement duration may vary depending on different terminal implementations.

[0316] In actual application, the measurement duration may be determined by reducing the measurement duration, the first factor, the measurement duration of a single carrier, a reference period, and other factors.

[0317] In practical applications, the total measurement time is related to at least one of the following factors:

[0318] number of samples;

[0319] Reference signal;

[0320] MGRP;

[0321] Number of frequency points.

[0322] Based on this, in one embodiment, the measurement duration is determined by one of the following formulas:

[0323] N1 x A x N2;

[0324] N1 x max (A, B ) x N2;

[0325] N1 x max (A, N3*B) x N2;

[0326] max(T1,N1 * C)*N2;

[0327] max(T1,N1 * max(B,C))*N2;

[0328] N1 * B*N2;

[0329] max(T1,N1 * max(C,D))*N2;

[0330] max(T1,N1 * max(A,C,D))*N2;

[0331] Wherein, N1, N2, and N3 are integers greater than or equal to 1; T1 is a constant; A represents the secondary carrier measurement period (measCycleSCell in English); B represents the discontinuous reception cycle period; C represents the reference signal measurement period (also called the reference signal period); D represents the MGRP; and max() represents the maximum value function.

[0332] N1 is associated with at least one of the following factors:

[0333] number of samples;

[0334] The positional relationship between SMTC and MGRP (complete overlap, partial overlap, and no overlap);

[0335] SMTC is related to the positional relationship of reference symbols (also called reference signals) used for Radio Link Monitor (RLM), Beam Failure Detection (BFD), Candidate Beam Detection (CBD), or Layer 1 Reference Signal Received Power (L1-RSRP).

[0336] That is to say, in actual application, the value of N1 can be determined according to at least one of the above factors.

[0337] N2 is related to the number of frequency points and / or the number of secondary carriers, etc. That is, in actual application, the value of N2 can be determined according to the number of frequency points and / or the number of secondary carriers, etc.

[0338] N3 is a predefined integer. In actual application, N3 can be determined in combination with the implementation of the terminal (that is, the processing capability of the terminal).

[0339] T1 is a fixed value, a fixed duration, such as 200ms, 600ms, or 800ms. The value of T1 can be set as needed.

[0340] In actual applications, considering the differences in terminal processing capabilities (mainly baseband processing capabilities), the network side can configure the terminals differently, such as configuring different thresholds and different measurement delay-related information.

[0341] Based on this, in one embodiment, the method may further include:

[0342] Report the terminal's capabilities to the network; the capabilities include at least one of the following:

[0343] whether the terminal supports carrier measurement based on the first factor;

[0344] The frequency points or frequency band combinations or CA combinations supported by the terminal and measured based on the first factor;

[0345] The time interval that needs to be satisfied between the time domains of the measurement reference signals of the multiple carriers supported by the terminal and completed within the first duration;

[0346] The time domain interval of SMTCs that the terminal can measure simultaneously;

[0347] The time domain interval of the CSI-RS measurement window that the terminal can measure simultaneously;

[0348] The time domain interval of the SMTC and CSI-RS measurement window that the terminal can simultaneously measure;

[0349] The time domain interval of the PRS that can be measured simultaneously by the terminal;

[0350] The time domain interval of the SMTC and PRS measurement window that the terminal can simultaneously measure;

[0351] The terminal can simultaneously measure the CSI-RS and PRS measurement windows in the time domain.

[0352] The first duration can be set as needed.

[0353] The carrier measurement may include intra-frequency measurement, inter-frequency measurement, inter-system measurement, CA measurement, DC or multi-connection measurement, SCC measurement, etc.

[0354] For frequency band combinations, the terminal may not support the relevant solution for all frequency band combinations, so the terminal can report the frequency band combinations that support the solution. In this way, after the network side learns this information, when it comes to measuring the frequency points in the frequency band combinations supported by the terminal, it can instruct the terminal to adopt the solution of the embodiment of the present application. When measuring the frequency points in the frequency band combinations that the terminal does not support, the terminal can perform the measurement based on the non-enhanced solution, that is, not using the solution of the embodiment of the present application for measurement.

[0355] Regarding the time domain interval reported by the terminal, in related technologies, the measurement of SMTC and / or CSI-RS at different frequencies is performed serially. In the embodiments of the present application, the terminal reports the time domain interval. To reduce the measurement duration, the measurement of certain frequencies that meet the time domain interval reported by the terminal (i.e., meet the time domain conditions for terminal reporting) can be performed in parallel or partially serially based on the first factor.

[0356] Here, for example, for the serial mode, assume that completing the measurement of one frequency requires five samples, with each sampling interval being T (T can be the SMTC period or the CSI-RS period). If measurements are performed on P frequency points, the duration to complete the P frequency point measurements is: 5*T*P. (As for the period of 5*T*N, whether the terminal completes the measurement of each frequency point sequentially before measuring the next frequency point (for example, after sampling F1 five times, then sampling F2 five times, and so on), or performs measurements in an interspersed manner (for example, sampling F1 once, F2 once, until Fn once, and then F1 once, etc.), it depends entirely on the terminal implementation.

[0357] The solution provided in this embodiment of the present application is to reduce measurement time by performing parallel or partially serial measurements on certain frequencies based on the first factor. For parallel measurement, the total time required to complete measurements on P frequencies is 5*T (applicable to scenarios where the SMTC periods and / or SMTC offsets for the P frequencies are the same). Alternatively, the total time required to complete measurements on P frequencies can be max(5*T1, 5*T2, …, 5*Tn), applicable to scenarios where the SMTC periods for the P frequencies are different (T1, T2, …, Tn are the SMTC periods for different frequencies). The partially serial solution is applicable to scenarios where the SMTCs of different frequencies have a certain time domain offset, preventing simultaneous reception by the terminal. Alternatively, even if the SMTCs have the same or similar time domain offsets, the terminal needs to cache and process them sequentially due to limited processing capabilities. For measurements on P frequencies, the total measurement time for the partially serial solution is slightly longer than that for the parallel solution, but shorter than that for the fully serial solution.

[0358] That is to say, in the solution adopted in the embodiment of the present application, the terminal performs parallel measurement (for example, considering complete non-overlap in the time domain and / or the processing capability of the terminal) or partial serial measurement on the carrier based on the first factor.

[0359] The measurement method provided in the embodiment of the present application is that the terminal performs measurement based on a first factor; the first factor is associated with at least one of the first information and the second information; the first information represents the time domain position relationship of the reference signal of the carrier; the second information represents the number of carriers. The solution provided in the embodiment of the present application takes into account the time domain position relationship of the reference signals between different carriers, so that in high-speed mobile scenarios, the measurement delay can be reduced during measurement and the terminal measurement performance can be improved.

[0360] The embodiment of the present application also provides a measurement method, which is applied to a terminal, such as Figure 2 As shown, the method includes:

[0361] Step 201: perform measurement based on a second factor; the second factor is associated with secondary carrier measurement.

[0362] In one embodiment, the terminal measures the secondary carrier based on the second factor.

[0363] The solution of the embodiment of the present application can be applied to CA, dual connection or multi-connection scenarios.

[0364] In the high-speed rail scenario, it is necessary to reduce the measurement delay. Considering that there are measurements that require measurement intervals and measurements that do not require measurement intervals, a second factor is introduced. Therefore, the second factor is specifically associated with whether a measurement requires a measurement interval.

[0391] Here, when the total number of secondary carriers includes only the number of secondary carriers whose SMTC and measurement interval completely overlap, the value of the second factor is defined as 1. When the total number of secondary carriers includes only the number of secondary carriers whose SMTC and measurement interval partially overlap, the value of the second factor is defined as 1.

[0411] Secondary carrier based on SSB measurement;

[0412] Secondary carrier based on CSI-RS measurement;

[0413] Secondary carrier based on PRS measurement.

[0414] Here, considering that the same network can serve multiple scenarios simultaneously, different factors can be considered in different scenarios, resulting in different values ​​for the first factor. For example, different first factor values ​​are used for eMBB services, URLLC services, and mMTC services; for example, different second factor values ​​are used for high-speed rail (i.e., high-speed) scenarios and non-high-speed rail (i.e., non-high-speed) scenarios.

[0415] In actual application, when measuring based on the first factor, the measurement behavior of the terminal may be defined as follows:

[0416] The measurement of multiple target carriers needs to be completed within a certain time, which is related to factors such as the measurement time of a single carrier and the second factor.

[0417] In actual application, the terminal needs to first determine the second factor and then perform measurement based on the first factor.

[0418] Based on this, in one embodiment, if Figure 2 As shown, the method may further include:

[0419] Step 200: Determine the second factor.

[0420] Specifically, the terminal may determine the second factor based on whether the terminal has a measurement requiring a measurement interval; the terminal may also determine the second factor based on whether the terminal has a measurement of a secondary carrier whose reference signal and measurement interval completely overlap; the terminal may also determine the second factor based on network information.

[0421] The determining of the second factor according to whether the terminal performs measurement requiring a measurement interval means that the terminal autonomously determines whether the second factor is required and a value of the second factor if the second factor is required, based on at least one of the following:

[0422] Whether the measurement target or carrier (including PCC and / or SCC) requires a measurement gap;

[0423] The number of carriers (including PCC and / or SCC) that require measurement intervals;

[0424] The number of carriers (including PCC and / or SCC) that do not require a measurement gap.

[0425] And the value of the second factor in the scenario where the second factor is needed.

[0426] Accordingly, the terminal autonomously determines the second factor according to whether the terminal has a measurement of a secondary carrier whose reference signal and measurement interval completely overlap.

[0427] Here, the reference signal includes at least one of the following:

[0428] SSB;

[0429] CSI-RS;

[0430] PRS.

[0431] Acquiring the second factor according to network information means that the network side indicates the value of the second factor. The network side may indicate the second factor through signaling, such as RRC signaling, MAC CE, or DCI.

[0432] When the terminal autonomously determines the second factor, the second factor may be determined in the above manner.

[0433] Specifically, in one embodiment, when there is a secondary carrier that requires a measurement interval or there is a measurement of a secondary carrier whose reference signal and the measurement interval completely overlap, the second factor is determined to be the sixth value. Here, the value of the second factor is the sixth value, and the sixth value can be the difference and / or number contained in the second factor in the above-mentioned high-speed rail scenario. Exemplarily, assuming that the total number of secondary carriers is 3 and the number of secondary carriers that require a measurement interval is 1, the value of the second factor can be 3-1=2. For another example, assuming that the total number of secondary carriers is 3, the number of SMTC secondary carriers and the number of secondary carriers whose measurement interval completely overlaps are 1, the value of the second factor can be 3-1=2.

[0434] In practical applications, directly determining the value of the second factor using the above method can improve measurement performance (i.e., reduce measurement latency), but may also increase terminal measurement complexity. Therefore, to balance measurement performance and terminal implementation complexity, the value of the second factor may not be the difference and / or number included in the above second factor.

[0435] Based on this, in one embodiment, when there is a secondary carrier requiring a measurement gap or there is measurement of a secondary carrier whose reference signal and measurement gap completely overlap, and the number of secondary carriers requiring a measurement gap meets the tenth threshold, the second factor is determined to be the seventh value.

[0436] The seventh value differs from the difference and / or number included in the second factor in the same scenario. Instead, it is amplified to some extent, which can also be understood as relaxation. For example, here, the second factor is the sixth value, which can be the difference and / or number included in the second factor in the high-speed rail scenario. For example, assuming the total number of secondary carriers is 3 and the number of secondary carriers requiring measurement intervals is 1, then, according to the difference and / or number included in the second factor, the second factor value can be 3-1=2. However, considering the complexity of terminal measurement implementation, i.e., considering the terminal's implementation capabilities, thereby reducing terminal implementation complexity, the second factor value can be 3. For another example, assuming the total number of secondary carriers is 3 and the number of secondary carriers whose number of SMTC secondary carriers and measurement intervals completely overlap is 2, then, according to the difference and / or number included in the second factor, the second factor value can be 1. However, considering the complexity of terminal measurement implementation, i.e., considering the terminal's implementation capabilities, thereby reducing terminal implementation complexity, the second factor value can be 2.

[0437] In actual application, the seventh value can be indicated by the network side (it can also be understood as being notified by the network side), for example, the network side indicates the seventh value to the terminal through RRC signaling, MAC CE or DCI, etc., or it can be pre-defined and thus pre-set in the terminal, or it can be determined by the terminal itself.

[0438] The tenth threshold may also be indicated by the network side, for example, the network side indicates the tenth threshold to the terminal through RRC signaling, MAC CE or DCI, that is, the terminal receives the tenth threshold, or it may be predefined and thus pre-set in the terminal.

[0439] When the secondary carrier measurement period (measCycleSCell) is large and there are many measurement opportunities (SMTC, CSI-RS, measurement gap (MG, PRS)) within the secondary carrier measurement period, the positional relationship between the reference signal and the MGRP does not need to be considered.

[0440] Based on this, in one embodiment, the second factor includes at least one of the following:

[0441] When the secondary carrier measurement period is greater than or equal to the eleventh threshold, the second factor is equal to the eleventh value;

[0442] When the secondary carrier measurement period is less than or equal to the twelfth threshold, the second factor is equal to E / (E-(C / D)); wherein C represents the reference signal measurement period; D represents the MGRP; and E represents the eleventh value.

[0443] Among them, when the secondary carrier measurement period is greater than or equal to the eleventh threshold, it means that the measurement opportunities are relatively few, so the secondary carrier is measured as much as possible in each measurement period; when the secondary carrier measurement period is less than or equal to the twelfth threshold, it means that the measurement opportunities are relatively many.

[0444] The eleventh threshold and the twelfth threshold can be set as needed. The eleventh threshold can be indicated by the network side, such as the network side indicating the eleventh threshold to the terminal through RRC signaling, MAC CE or DCI, that is, the terminal receives the eleventh threshold, or it can be pre-defined and thus pre-set in the terminal; accordingly, the twelfth threshold can be indicated by the network side, such as the network side indicating the twelfth threshold to the terminal through RRC signaling, MAC CE or DCI, that is, the terminal receives the twelfth threshold, or it can be pre-defined and thus pre-set in the terminal.

[0445] In actual application, the value of the eleventh value can be 1.

[0446] In actual applications, considering the differences in terminal processing capabilities (mainly baseband processing capabilities), the network side can configure the terminals differently, such as configuring different thresholds and different second factor values.

[0447] Based on this, in one embodiment, the method may further include:

[0448] Report the terminal's capabilities to the network; the capabilities include at least one of the following:

[0449] whether the terminal supports measurement based on the second factor;

[0450] a frequency point or frequency band combination or carrier aggregation combination supported by the terminal and measured based on the second factor.

[0451] That is to say, the solution adopted in the embodiment of the present application is similar to the measurement based on the first factor. The terminal performs parallel measurement (for example, considering whether a measurement interval and / or the processing capability of the terminal is required) or partial serial measurement on the carrier based on the second factor, thereby reducing the total measurement time.

[0452] In the measurement method provided in the embodiment of the present application, the terminal performs measurement based on a second factor; the second factor is associated with the secondary carrier measurement. The solution provided in the embodiment of the present application takes into account the reference signal configuration of the secondary carrier, thereby reducing the measurement delay during measurement in high-speed mobile scenarios and improving the terminal measurement performance.
