The CU-DU structure can separate the protocol layer of the access network device. Some protocol layer functions are centrally controlled by the CU, while the remaining part or all protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.

[0278] In some embodiments, the core network equipment may be a single device, including a first network element, a second network element, etc., or it may be multiple devices or a group of devices, each including all or part of the first network element, the second network element, etc. Network elements may be virtual or physical.

[0282] During RRM measurement, the network device configures the terminal device to perform signal quality measurements on multiple carriers. The terminal device performs signal quality measurements on multiple carriers according to the network device's configuration, obtains the measurement results, and sends the measurement results to the network device.

[0283] In some embodiments, the terms "component carrier (CC)," "cell," "frequency carrier," and "carrier frequency" can be used interchangeably.

[0284] In some embodiments, terms such as “send,” “transmit,” “report,” “distribute,” “transfer,” “bidirectional transmission,” “send and / or receive” can be used interchangeably.

[0285] The measurement results are used to evaluate the connection quality between terminal devices and network devices. When a terminal device moves between different cells or sectors, the network device can determine the most suitable target cell for handover based on the measurement results sent by the terminal device.

[0286] When a terminal device is configured to perform RRM measurements on cells corresponding to different carriers, the terminal device needs to perform sequential measurements on each carrier. After completing the signal quality measurement on one carrier, the terminal device can switch to another carrier to continue the signal quality measurement. The measurement report can only be sent to the network device after the terminal device has completed the signal quality measurements on all carriers, resulting in a significant measurement delay. This measurement delay represents the time from when the terminal device begins performing signal quality measurements on a carrier to when it sends the measurement report to the network device. If the measurement delay is significant, the network device may miss the optimal time for handover decisions, leading to data transmission failure.

[0287] To address the aforementioned problems, this disclosure provides a communication method, terminal device, network device, communication equipment, communication system, storage medium, and program product. The terminal device, based on its signal quality prediction capability, performs signal quality measurement on at least one first carrier to obtain a first measurement result, and performs signal quality prediction on at least one second carrier to obtain a predicted second measurement result. The terminal device then sends the first and second measurement results to the network device. Since the second measurement result is obtained by the terminal device predicting the signal quality of at least one second carrier, the terminal device does not need to sequentially perform signal quality measurements on the second carriers, reducing the time required for the terminal device to obtain the second measurement result, and thus reducing the measurement latency of the terminal device.

[0288] The following detailed description, with reference to the accompanying drawings, describes the communication methods, terminal equipment, network equipment, communication equipment, communication systems, storage media, and program products provided in this disclosure.

[0289] In some embodiments, for RRM measurement, if the network device is configured with N carriers, the terminal device will perform signal quality measurements on these carriers in sequence, wherein these N carriers are specified in the carrier specific scaling factor (CSSF) parameter.

[0290] In some embodiments, the network device configures a measurement object (MO) for the terminal. Based on the MO, the CSSF (the carrier to be measured), the reference signal type to be measured on the carrier, and the configuration resources to be measured on the carrier can be determined. The reference signal type may include, for example, CSI-RS, SSB, etc., and the configuration resources may include, for example, time-domain resources and / or frequency-domain resources.

[0291] The method for determining the intra-frequency measurement period without MG can be found in Table 1.

[0292] Table 1

[0293] In Table 1, TSSB_measurement_period_intra represents the intra-frequency measurement period, max() indicates taking the maximum value in the parentheses, and K p As a shared factor, the SMTC period is the SSB-based measurement time configuration (SMTC) period, CSSF. intra For intra-frequency measurements without MG, ceil represents the rounding up factor. Regarding the SMTC period, if different SMTC periods are configured for different cells, the SMTC period mentioned in Table 1 refers to the SMTC period used by the cell corresponding to the measured carrier. Table 1 provides examples of the measurement periods corresponding to different Discontinuous Reception (DRX) periods.

[0294] The calculation method for the carrier scaling factor without MG in standalone (SA) scenarios can be found in Table 2.

[0295] Table 2

[0296] In some embodiments, for FR1+FR2 carrier aggregation (CA), only one FR1 operating band and one FR2 operating band are included.

[0297] In some embodiments, the selection of the FR2 secondary component carrier (SCC) for which neighbor cell measurements are required follows clause 9.2.3.2.

[0298] In some embodiments, if only one secondary cell is configured, and there is no inter-frequency MO without MG, and only SSB-based L3 measurements are configured on the secondary carrier, then CSSF outside_gap,i =1; If only one secondary cell is configured, and there is no cross-frequency MO without MG, and L3 measurements based on SSB and / or CSI-RS are configured on the secondary carrier, then CSSF outside_gap,i =2.

[0299] In some embodiments, Y represents the number of cross-frequency MOs in the measured MG-free configuration; otherwise, Y is 0.

[0300] In some embodiments, the inter-band CA of FR2 includes only two NR FR2 operating frequency bands.

[0301] In some embodiments, if the primary component carrier (PCC) is configured with L3 measurements based on SSB and / or CSI-RS, then N PCC_CSIRS =1; otherwise, N PCC_CSIRS =0.

[0302] In some embodiments, N SCC_CSIRS This indicates the number of secondary cells configured with L3 measurements based on SSB and / or CSI-RS.

[0308] Referring to Figure 2a, which is an exemplary interactive schematic diagram of a communication method provided according to an embodiment of the present disclosure. As shown in Figure 2a, the communication method includes the following steps:

[0309] Step S201: The terminal device sends its signal quality prediction capability to the network device.

[0310] In some embodiments, the signal quality prediction capability of a terminal device refers to the terminal device's ability to predict the signal quality of a carrier wave using artificial intelligence (AI). When a terminal device possesses signal quality prediction capability, it can predict the measurement results of another portion of the carrier waves based on the measurement results of one portion.

[0311] Please refer to Figure 2b, which is an exemplary schematic diagram illustrating the principle of AI-based carrier signal quality prediction according to an embodiment of this disclosure. As shown in Figure 2b, the configured carriers include CC1, CC2, CC3, ..., CC x CC x+1 CC x+2 ..., CC y Let x and y be positive integers. If the signal quality prediction capability of the terminal device indicates that the terminal device can predict the signal quality of y carriers based on the measurement results of x carriers, then the input of the AI ​​model can include: the measurement results of CC1, the measurement results of CC2, ..., CC x The measurement results. Then, the AI ​​model uses the measurement results of CC1, CC2, ..., CC... x The measurement results are used to predict signal quality, therefore the output of the AI ​​model can include CC. x+1 Measurement results, CC x+2 Measurement results, ..., CC y The measurement results.

[0312] In some embodiments, the carrier measurement results may include at least one of reference signal received power (RSRP), reference signal received quality (RSRQ), and signal to interference plus noise ratio (SINR).

[0313] Taking CC1 in Figure 2b as an example, the measurement results of CC1 can include RSRP obtained by performing signal quality measurement on CC1, that is, the measured RSRP corresponding to CC1; the measurement results of CC1 can include RSRQ obtained by performing signal quality measurement on CC1, that is, the measured RSRQ corresponding to CC1; the measurement results of CC1 can include SINR obtained by performing signal quality measurement on CC1, that is, the measured SINR corresponding to CC1.

[0314] Taking the carrier as CC in Figure 2b y For example, CC y The measurement results can include the CC y The RSRP obtained from signal quality prediction, i.e., CC y Corresponding predicted RSRP; CC y The measurement results can include the CC y The RSRQ obtained by performing signal quality prediction, i.e., CC y Corresponding predicted RSRQ; CC y The measurement results can include the CC y SINR obtained by signal quality prediction, i.e., CC y The corresponding predicted SINR.

[0315] In the example in Figure 2, the inputs to the AI ​​model include the measured RSRP corresponding to CC1, the measured RSRP corresponding to CC2, ..., CC x The corresponding measured RSRP and the output of the AI ​​model include CC. x+1 Corresponding predicted RSRP, CC x+2 The corresponding predicted RSRP, ..., CC y The corresponding predicted RSRP.

[0316] In some embodiments, the terminal device sends capability information to the network device, which is used to indicate the terminal device's signal quality prediction capability.

[0317] In some embodiments, the names of information, etc., are not limited to the names described in the embodiments. Terms such as "information", "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "domain", "field", "symbol", "symbol", "codebook", "codeword", "codepoint", "bit", "data", "program", and "chip" can be used interchangeably.

[0318] In some embodiments, the capability information includes at least one of the following:

[0319] The first number of carrier waves measured by the terminal device;

[0320] The second number of carriers predicted by the terminal device;

[0321] The sum of the first and second quantities;

[0322] The ratio of the first quantity to the second quantity;

[0323] The ratio of the first quantity to the sum;

[0324] The ratio of the second quantity to the sum.

[0325] The first quantity refers to the number of carriers actually used for signal quality measurement by the terminal device during RRM measurement. The second quantity refers to the number of carriers used for signal quality prediction by the terminal device during RRM measurement. The sum of the first and second quantities represents the total number of carriers configured by the terminal device during RRM measurement, including both the number of carriers used for signal quality measurement and the number used for signal quality prediction. The ratio of the first and second quantities, which is the ratio between the number of carriers used for signal quality measurement and the number used for signal quality prediction, allows the network device to determine the measurement results obtained for each of the first number of carriers measured and to predict the measurement results for the second number of carriers. The ratio of the first quantity to the sum, which is the ratio of the number of carriers used for signal quality measurement to the total number of carriers configured, allows the network device to determine the final measurement result for each of the first number of carriers measured and ultimately, the total number of carriers whose measurement results can be obtained. The second quantity is the ratio of the sum to the number of carriers used by the terminal device for signal quality prediction to the total number of configured carriers. Based on this ratio, the network device can determine how many of the total number of configured carriers can be measured using signal quality prediction.

[0326] The configuration carriers shown in Figure 2b include CC1, CC2, CC3, ..., CC x CC x+1 CC x+2 ..., CC y For example, the carriers used by the terminal equipment to actually perform signal quality measurements include CC1, CC2, CC3, ..., CC x Therefore, the first quantity is x, and the carriers used by the terminal device for signal quality prediction include CC. x+1 CC x+2 ..., CC y Therefore, the second quantity is (yx), the sum of the first and second quantities is y, and the ratio of the first and second quantities is x / (yx). The ratio of the first quantity to the sum is x / y, and the ratio of the second quantity to the sum is (yx) / y.

[0327] In step S202, the terminal device performs signal quality measurement on at least one first carrier to obtain a first measurement result based on its signal quality prediction capability, and performs signal quality prediction on at least one second carrier to obtain a predicted second measurement result.

[0328] In some embodiments, the terminal device performs signal quality measurements on at least one first carrier, and the resulting first measurement result includes the measurement results for each first carrier. Specifically, for each first carrier, the measurement result may include at least one of the measured RSRP, the measured RSRQ, and the measured SINR corresponding to the first carrier. For each second carrier, the measurement result may include at least one of the predicted RSRP, the predicted RSRQ, and the predicted SINR corresponding to the second carrier.

[0329] In some embodiments, the terminal device performs signal quality prediction on at least one second carrier based on a first measurement result to obtain a second measurement result. For example, if at least one first carrier includes CC1, CC2, CC3, and CC4, and at least one second carrier includes CC5 and CC6, then the terminal device performs signal quality prediction on CC5 and CC6 based on the measurement results of CC1, CC2, CC3, and CC4, and the obtained second measurement result includes the measurement results of CC5 and CC6.

[0330] In some embodiments, the terminal device performs signal quality prediction on at least one second carrier based on the measurement results of a portion of the first carriers in the first measurement result, to obtain a second measurement result. For example, if at least one first carrier includes CC1, CC2, CC3, and CC4, and at least one second carrier includes CC5 and CC6, then the terminal device performs signal quality prediction on CC5 and CC6 based on the measurement results of CC1, CC2, and CC3, and the obtained second measurement result includes the measurement results of CC5 and CC6. That is, for any one of the first carriers, the measurement result of that first carrier may or may not be used for signal quality prediction.

[0331] In some embodiments, the signal quality prediction capability of the terminal device includes a first prediction capability and / or a second prediction capability.

[0332] In some embodiments, the first prediction capability is the terminal device's prediction capability for measurement without MG (Meaning Gauge). Based on the first prediction capability, the terminal device can perform signal quality measurement on a first type of measurement carrier and predict signal quality on a first type of prediction carrier. Both the first type of measurement carrier and the first type of prediction carrier are carriers configured for signal quality measurement without MG. For any carrier configured for signal quality measurement without MG, since its frequency point is located on the active bandwidth part (BWP), the terminal device does not need to configure MG when performing signal quality measurement on that carrier.

[0333] In some embodiments, the CSSF in a signal quality measurement scenario without MG is denoted as CSSF. outside_gap According to CSSF outside_gap The number of carriers configured with signal quality measurement without MG can be determined (this number is denoted as d, where d is a positive integer). Then, the terminal device can perform signal quality measurement on d1 of these carriers based on the first prediction capability, obtain the measurement results of d1 carriers, and perform signal quality prediction on (d-d1) of these carriers, obtain the measurement results of (d-d1) carriers.

[0334] Specifically, for a carrier configured with signal quality measurement without MG, the first number of carriers measured by the terminal device is d1, the second number of carriers predicted by the terminal device is (d-d1), the sum of the first and second numbers is d, the ratio of the first and second numbers is d1 / (d-d1), the ratio of the first number to the sum is d1 / d, and the ratio of the second number to the sum is (d-d1) / d. Optionally, the first prediction capability can be indicated by at least one of the following: d1, (d-d1), d, d1 / (d-d1), d1 / d, (d-d1) / d.

[0335] In some embodiments, a carrier for signal quality measurement without MG is configured, including at least one of the following: a secondary carrier for signal quality measurement based on SSB is configured; a carrier for signal quality measurement at different frequencies without MG is configured; a carrier for signal quality measurement at different systems without MG is configured.

[0336] In some embodiments, the first predictive capability is used to indicate at least one of the following:

[0337] a. The terminal equipment's ability to predict signal quality based on SSB.

[0338] In some embodiments, the network device is configured with an auxiliary carrier for SSB-based signal quality measurement, including a first auxiliary carrier and a second auxiliary carrier of the terminal device. The terminal device has the ability to predict the SSB-based signal quality and can predict the measurement result of the second auxiliary carrier based on the measurement result of the first auxiliary carrier and / or the measurement result of the main carrier.

[0339] In some embodiments, the number of first secondary carriers can be one or more, and the number of second secondary carriers can be one or more.

[0340] In some embodiments, at least one first carrier includes a first secondary carrier and / or a primary carrier, and at least one second carrier includes a second secondary carrier. The measurement results of the first secondary carrier and / or the primary carrier are used to predict the measurement results of the second secondary carrier. The first secondary carrier and the second secondary carrier are secondary carriers configured with SSB-based signal quality measurement. The terminal device's ability to predict SSB-based signal quality is defined as follows: the terminal device's ability to predict SSB-based signal quality under a first condition, wherein the first condition includes at least one of the following conditions 1.1 to 1.11:

[0341] Condition 1.1: The frequency points of the first auxiliary carrier, the primary carrier, and the second auxiliary carrier are all within FR1.

[0342] In some embodiments, the frequency point of the carrier refers to the center frequency point of the carrier. If the frequencies of the first auxiliary carrier, the primary carrier, and the second auxiliary carrier are all within FR1, it means that the center frequencies of the first auxiliary carrier, the primary carrier, and the second auxiliary carrier are all within FR1. When the frequencies of the first auxiliary carrier, the primary carrier, and the second auxiliary carrier are all within FR1, it corresponds to the CA case only within FR1.

[0343] Condition 1.2: The frequency points of the first auxiliary carrier, the primary carrier, and the second auxiliary carrier are in the same frequency band within FR2.

[0344] When the frequency points of the first auxiliary carrier, the primary carrier, and the second auxiliary carrier are all in the same frequency band within FR2, it corresponds to the case of in-band CA of only FR2.

[0345] Condition 1.3: The frequency points of the first auxiliary carrier and the second auxiliary carrier are in different frequency bands within FR2.

[0346] When the frequency points of the first auxiliary carrier and the second auxiliary carrier are in different frequency bands within FR2, it corresponds to the case of inter-band CA of only FR2.

[0347] Condition 1.4: The frequency points of the primary carrier and the secondary carrier are in different frequency bands within FR2.

[0348] When the frequencies of the primary carrier and the secondary carrier are in different frequency bands within FR2, it corresponds to the case of inter-band CA of only FR2.

[0349] Condition 1.5: The frequency points of the first auxiliary carrier and the second auxiliary carrier are both within FR2, and the frequency point of the main carrier is within FR1.

[0350] When the frequencies of the first and second auxiliary carriers are both within FR2, and the frequency of the primary carrier is within FR1, it corresponds to the CA case of FR1+FR2, where the frequency of the primary carrier is within FR1.

[0351] Condition 1.6: The frequency points of the first auxiliary carrier and the second auxiliary carrier are both within FR1, and the frequency point of the main carrier is within FR2.

[0352] When the frequencies of the first and second auxiliary carriers are both within FR1, and the frequency of the primary carrier is within FR2, it corresponds to the CA case of FR1+FR2, where the frequency of the primary carrier is within FR2.

[0353] Condition 1.7: The cell corresponding to the first secondary carrier and the cell corresponding to the second secondary carrier have a co-location relationship.

[0354] In some embodiments, there is an overlap in coverage area between the cell corresponding to the first secondary carrier and the cell corresponding to the second secondary carrier, which can determine that the cell corresponding to the first secondary carrier and the cell corresponding to the second secondary carrier have a co-location relationship.

[0355] Condition 1.8: The power difference between the cell corresponding to the first secondary carrier and the cell corresponding to the second secondary carrier is less than or equal to the first power difference threshold.

[0356] In some embodiments, the terminal device can determine the RSRP value of the cell corresponding to the first secondary carrier based on the historical measurement results of the first secondary carrier, and determine the RSRP value of the cell corresponding to the second secondary carrier based on the historical measurement results of the second secondary carrier, thereby obtaining the power difference value based on these two RSRP values. Then, the power difference value is compared with a first power difference threshold to determine whether the power difference value is less than or equal to the first power difference threshold. If the power difference value is less than or equal to the first power difference threshold, it indicates that the RSRP value of the cell corresponding to the first secondary carrier is relatively close to the RSRP value of the cell corresponding to the second secondary carrier, and therefore the measurement result of the second secondary carrier can be predicted based on the measurement result of the first secondary carrier.

[0357] In some embodiments, the first power difference threshold may be a preset power difference threshold or a power difference threshold configured by the network device.

[0358] Condition 1.9: The round-trip delay between the cell corresponding to the first secondary carrier and the cell corresponding to the second secondary carrier is less than or equal to the first round-trip delay threshold.

[0359] In some embodiments, the round-trip delay between the cell corresponding to the first secondary carrier and the cell corresponding to the second secondary carrier can be the total time required for the signal to travel from the cell corresponding to the first secondary carrier to the cell corresponding to the second secondary carrier, and then from the cell corresponding to the second secondary carrier back to the cell corresponding to the first secondary carrier. The terminal device can compare this round-trip delay with a first round-trip delay threshold. If the round-trip delay is less than or equal to the first round-trip delay threshold, it indicates that the distance between the cell corresponding to the first secondary carrier and the cell corresponding to the second secondary carrier is small. Therefore, the measurement result of the second secondary carrier can be predicted based on the measurement result of the first secondary carrier.

[0360] In some embodiments, terms such as “moment,” “point in time,” “time,” and “time location” can be used interchangeably, as can terms such as “duration,” “segment,” “time window,” “window,” and “time.”

[0361] In some embodiments, the first round-trip delay threshold may be a preset round-trip delay threshold or a round-trip delay threshold configured by the network device.

[0362] Condition 1.10: The spatial correlation between the cell corresponding to the first secondary carrier and the cell corresponding to the second secondary carrier is greater than or equal to the first spatial correlation threshold.

[0363] In some embodiments, the spatial correlation between the cell corresponding to the first secondary carrier and the cell corresponding to the second secondary carrier can be the degree of similarity or correlation between the reference signals on the first secondary carrier and the reference signals on the second secondary carrier in terms of spatial location. If the spatial correlation is greater than or equal to a first spatial correlation threshold, it indicates that the reference signals on the first secondary carrier and the reference signals on the second secondary carrier are highly similar or correlated in spatial location, and therefore the measurement results of the second secondary carrier can be predicted based on the measurement results of the first secondary carrier.

[0364] In some embodiments, the first spatial correlation threshold may be a preset spatial correlation threshold or a spatial correlation threshold configured by the network device.

[0365] Condition 1.11: The spectral correlation between the first secondary carrier and the second secondary carrier is greater than or equal to the first spectral correlation threshold.

[0366] In some embodiments, the spectral correlation between carriers refers to the degree of similarity in spectral shape, frequency distribution, and energy distribution between different carriers in the frequency domain. If the spectral correlation between the first auxiliary carrier and the second auxiliary carrier is greater than or equal to the first spectral correlation threshold, it indicates that the first auxiliary carrier and the second auxiliary carrier are highly similar in spectral shape, frequency distribution, and energy distribution. Therefore, the measurement results of the second auxiliary carrier can be predicted based on the measurement results of the first auxiliary carrier.

[0367] In some embodiments, the first spectrum correlation threshold may be a preset spectrum correlation threshold or a spectrum correlation threshold configured by the network device.

[0368] b. The terminal equipment's ability to predict the quality of signals from different frequency points without MG.

[0369] In some embodiments, the network device is configured with a carrier for measuring the signal quality of an inter-frequency point without MG, including a first inter-frequency point carrier and a second inter-frequency point carrier of the terminal device. The terminal device has the ability to predict the signal quality of an inter-frequency point without MG and can predict the measurement result of the second inter-frequency point carrier based on the measurement result of the first inter-frequency point carrier.

[0370] In some embodiments, the number of first inter-frequency carriers can be one or more, and the number of second inter-frequency carriers can also be one or more. That is, the correspondence between the first inter-frequency carriers and the second inter-frequency carriers can be one-to-one, one-to-many, many-to-one, or many-to-many.

[0371] In some embodiments, at least one first carrier includes a first inter-frequency carrier, at least one second carrier includes a second inter-frequency carrier, the measurement result of the first inter-frequency carrier is used to predict the measurement result of the second inter-frequency carrier, and the first inter-frequency carrier and the second inter-frequency carrier are carriers configured with inter-frequency signal quality measurement without MG.

[0372] The terminal device's ability to predict the quality of inter-frequency signals without MG is defined as follows: Under a second condition, the terminal device's ability to predict the quality of inter-frequency signals without MG, wherein the second condition includes at least one of the following conditions 2.1 to 2.5:

[0373] Condition 2.1: The cell corresponding to the first inter-frequency carrier and the cell corresponding to the second inter-frequency carrier have a co-location relationship.

[0374] In some embodiments, the cell corresponding to the first inter-frequency carrier and the cell corresponding to the second inter-frequency carrier have overlapping coverage areas, which indicates that the cells corresponding to the first inter-frequency carrier and the second inter-frequency carrier have a co-location relationship. Therefore, the measurement results of the second inter-frequency carrier can be predicted based on the measurement results of the first inter-frequency carrier.

[0375] Condition 2.2: The power difference between the cell corresponding to the first inter-frequency carrier and the cell corresponding to the second inter-frequency carrier is less than or equal to the second power difference threshold.

[0376] In some embodiments, the terminal device can obtain the RSRP value on the cell corresponding to the first inter-frequency carrier and the RSRP value on the cell corresponding to the second inter-frequency carrier, thereby obtaining the power difference between the cell corresponding to the first inter-frequency carrier and the cell corresponding to the second inter-frequency carrier based on these two RSRP values. These two RSRP values ​​can be obtained from historical measurements by the terminal device. The terminal device then compares this power difference with a second power difference threshold to determine whether the power difference is less than or equal to the second power difference threshold. If the power difference is less than or equal to the second power difference threshold, it indicates that the RSRP values ​​on the cell corresponding to the first inter-frequency carrier and the cell corresponding to the second inter-frequency carrier are relatively close, and therefore the measurement result of the second inter-frequency carrier can be predicted based on the measurement result of the first inter-frequency carrier.

[0377] In some embodiments, the second power difference threshold may be a preset power difference threshold or a power difference threshold configured by the network device.

[0378] Condition 2.3: The round-trip delay between the cell corresponding to the first inter-frequency carrier and the cell corresponding to the second inter-frequency carrier is less than or equal to the second round-trip delay threshold.

[0379] In some embodiments, the round-trip delay between the cell corresponding to the first inter-frequency carrier and the cell corresponding to the second inter-frequency carrier can be the total time required for a signal to travel from the cell corresponding to the first inter-frequency carrier to the cell corresponding to the second inter-frequency carrier, and then back from the cell corresponding to the second inter-frequency carrier to the cell corresponding to the first inter-frequency carrier. The terminal device can compare this round-trip delay with a second round-trip delay threshold. If the round-trip delay is less than or equal to the second round-trip delay threshold, it indicates that the distance between the cell corresponding to the first inter-frequency carrier and the cell corresponding to the second inter-frequency carrier is small. Therefore, the measurement result of the second inter-frequency carrier can be predicted based on the measurement result of the first inter-frequency carrier.

[0380] In some embodiments, the second round-trip delay threshold may be a preset round-trip delay threshold or a round-trip delay threshold configured by the network device.

[0381] Condition 2.4: The spatial correlation between the cell corresponding to the first inter-frequency carrier and the cell corresponding to the second inter-frequency carrier is greater than or equal to the second spatial correlation threshold.

[0382] In some embodiments, the spatial correlation between the cell corresponding to the first inter-frequency carrier and the cell corresponding to the second inter-frequency carrier can be the degree of similarity or correlation between the reference signal on the first inter-frequency carrier and the reference signal on the second inter-frequency carrier in terms of spatial location. If the spatial correlation is greater than or equal to a second spatial correlation threshold, it indicates that the reference signal on the first inter-frequency carrier and the reference signal on the second inter-frequency carrier have a high degree of similarity or correlation in spatial location, and therefore the measurement result of the second inter-frequency carrier can be predicted based on the measurement result of the first inter-frequency carrier.

[0383] In some embodiments, the second spatial correlation threshold may be a preset spatial correlation threshold or a spatial correlation threshold configured by the network device.

[0384] Condition 2.5: The spectral correlation between the first and second different frequency carriers is greater than or equal to the second spectral correlation threshold.

[0385] In some embodiments, if the spectral correlation between the first inter-frequency carrier and the second inter-frequency carrier is greater than or equal to the second spectral correlation threshold, it indicates that the first inter-frequency carrier and the second inter-frequency carrier are highly similar in terms of spectral shape, frequency distribution, and energy distribution. Therefore, the measurement result of the second inter-frequency carrier can be predicted based on the measurement result of the first inter-frequency carrier.

[0386] In some embodiments, the second spectrum correlation threshold may be a preset spectrum correlation threshold or a spectrum correlation threshold configured by the network device.

[0387] c. The ability of terminal equipment to predict the signal quality of heterogeneous systems without MG.

[0388] In some embodiments, the network device is configured with a carrier for measuring the inter-system signal quality without MG, including a first inter-system carrier and a second inter-system carrier of the terminal device. The terminal device has the ability to predict the inter-system signal quality without MG and can predict the measurement result of the second inter-system carrier based on the measurement result of the first inter-system carrier.

[0389] In some embodiments, the correspondence between the first heterogeneous system carrier and the second heterogeneous system carrier can be one-to-one, one-to-many, many-to-one, or many-to-many.

[0390] In some embodiments, at least one first carrier includes a first inter-system carrier, at least one second carrier includes a second inter-system carrier, the measurement result of the first inter-system carrier is used to predict the measurement result of the second inter-system carrier, and the first inter-system carrier and the second inter-system carrier are carriers configured with inter-system signal quality measurement without MG.

[0391] The predictive capability of the terminal device for the signal quality of a heterogeneous system without MG is defined as follows: under a third condition, the predictive capability of the terminal device for the signal quality of a heterogeneous system without MG, wherein the third condition includes at least one of the following conditions 3.1 to 3.5:

[0392] Condition 3.1: The cells corresponding to the first inter-system carrier and the cells corresponding to the second inter-system carrier have a co-location relationship.

[0393] In some embodiments, if the coverage areas of the cell corresponding to the first inter-system carrier and the cell corresponding to the second inter-system carrier overlap, it can be determined that the cells corresponding to the first inter-system carrier and the cells corresponding to the second inter-system carrier have a co-location relationship. Therefore, the measurement results of the second inter-system carrier can be predicted based on the measurement results of the first inter-system carrier.

[0394] Condition 3.2: The power difference between the cell corresponding to the first inter-system carrier and the cell corresponding to the second inter-system carrier is less than or equal to the third power difference threshold.

[0395] In some embodiments, the terminal device can obtain the RSRP value on the cell corresponding to the first inter-system carrier and the RSRP value on the cell corresponding to the second inter-system carrier, thereby obtaining the power difference between the cell corresponding to the first inter-system carrier and the cell corresponding to the second inter-system carrier based on these two RSRP values. These two RSRP values ​​can be obtained from historical measurements by the terminal device. The terminal device then compares this power difference with a third power difference threshold. If the power difference is less than or equal to the third power difference threshold, it indicates that the RSRP values ​​on the cell corresponding to the first inter-system carrier and the cell corresponding to the second inter-system carrier are relatively close. Therefore, the measurement result of the second inter-system carrier can be predicted based on the measurement result of the first inter-system carrier.

[0396] In some embodiments, the third power difference threshold may be a preset power difference threshold or a power difference threshold configured by the network device.

[0397] Condition 3.3: The round-trip delay between the cell corresponding to the first inter-system carrier and the cell corresponding to the second inter-system carrier is less than or equal to the third round-trip delay threshold.

[0398] In some embodiments, the round-trip delay in condition 3.3 can be the total time required for a signal to travel from the cell corresponding to the first inter-system carrier to the cell corresponding to the second inter-system carrier, and then from the cell corresponding to the second inter-system carrier back to the cell corresponding to the first inter-system carrier. If the round-trip delay is less than or equal to a third round-trip delay threshold, it indicates that the distance between the cell corresponding to the first inter-system carrier and the cell corresponding to the second inter-system carrier is small, and therefore the measurement result of the second inter-system carrier can be predicted based on the measurement result of the first inter-system carrier.

[0399] In some embodiments, the third round-trip delay threshold may be a preset round-trip delay threshold or a round-trip delay threshold configured by the network device.

[0400] Condition 3.4: The spatial correlation between the cell corresponding to the first inter-system carrier and the cell corresponding to the second inter-system carrier is greater than or equal to the third spatial correlation threshold.

[0401] In some embodiments, the spatial correlation between the cell corresponding to the first inter-system carrier and the cell corresponding to the second inter-system carrier can be the degree of similarity or correlation between the reference signals on the first inter-system carrier and the reference signals on the second inter-system carrier in terms of spatial location. If the spatial correlation is greater than or equal to a third spatial correlation threshold, it indicates that the reference signals on the first inter-system carrier and the reference signals on the second inter-system carrier are highly similar or correlated in terms of spatial location, and therefore the measurement results of the second inter-system carrier can be predicted based on the measurement results of the first inter-system carrier.

[0402] In some embodiments, the third spatial correlation threshold may be a preset spatial correlation threshold or a spatial correlation threshold configured by the network device.

[0403] Condition 3.5: The spectral correlation between the first and second inter-system carriers is greater than or equal to the third spectral correlation threshold.

[0404] In some embodiments, if the spectral correlation between the first inter-system carrier and the second inter-system carrier is greater than or equal to the third spectral correlation threshold, it indicates that the first inter-system carrier and the second inter-system carrier are highly similar in terms of spectral shape, frequency distribution, and energy distribution. Therefore, the measurement results of the second inter-system carrier can be predicted based on the measurement results of the first inter-system carrier.

[0405] In some embodiments, the third spectrum correlation threshold may be a preset spectrum correlation threshold or a spectrum correlation threshold configured by the network device.

[0406] In some embodiments, the second prediction capability is the terminal device's prediction capability for measurements within the MG. Based on the second prediction capability, the terminal device can perform signal quality measurements on a second type of measurement carrier and predict signal quality on a second type of prediction carrier. Both the second type of measurement carrier and the second type of prediction carrier are carriers configured for signal quality measurement within the MG. For any carrier configured for signal quality measurement within the MG, since its frequency point is not located on the active BWP, the terminal device needs to perform signal quality measurements within the configured MG when performing signal quality measurements on that carrier.

[0407] In some embodiments, the CSSF in the signal quality measurement scenario within the MG is denoted as CSSF. within_gap According to CSSF within_gap If the number of carriers configured for signal quality measurement within the MG is determined (denoted as d, where d is a positive integer), then the terminal device can perform signal quality measurement on d1 of these carriers based on the second prediction capability, obtain the measurement results of d1 carriers, and perform signal quality prediction on (d-d1) of these carriers, obtain the measurement results of (d-d1) carriers.

[0408] Specifically, for a carrier configured with signal quality measurement within the MG, the terminal device measures a first number of carriers as d1, predicts a second number of carriers as (d-d1), the sum of the first and second numbers is d, the ratio of the first and second numbers is d1 / (d-d1), the ratio of the first number to the sum is d1 / d, and the ratio of the second number to the sum is (d-d1) / d. Optionally, the second prediction capability can be indicated by at least one of the following: d1, (d-d1), d, d1 / (d-d1), d1 / d, (d-d1) / d.

[0409] In some embodiments, a carrier for signal quality measurement within the MG is configured, including at least one of the following: a carrier for L3 measurement based on the Channel State Information Reference Signal (CSI-RS) within the MG is configured; a carrier for L3 measurement based solely on the SSB within the MG is configured; or a carrier for L1 measurement based on the SSB within the MG is configured.

[0410] In some embodiments, the second predictive capability is used to indicate at least one of the following df:

[0411] d. The terminal equipment's ability to predict the quality of L3 signals based on CSI-RS.

[0412] In some embodiments, the network device is configured with a carrier for L3 measurement based on CSI-RS within the MG. This L3 measurement based on CSI-RS within the MG can include L3 measurement based solely on CSI-RS within the MG, or it can include L3 measurement based on both CSI-RS and SSB within the MG. In other words, for a carrier configured with L3 measurement based on CSI-RS within the MG, the reference signal used by the terminal device for measurement / prediction on that carrier can be CSI-RS, or it can be both CSI-RS and SSB.

[0413] In some embodiments, the carriers in the L3 measurement based on CSI-RS within the MG include a third carrier and a fourth carrier. The terminal device has the ability to predict the quality of the L3 signal based on CSI-RS and can predict the measurement result of the fourth carrier based on the measurement result of the third carrier.

[0426] In some embodiments, if condition 4.5 is met, it means that the distance between the cell corresponding to the third carrier and the cell corresponding to the fourth carrier is small, so the measurement result of the fourth carrier can be predicted based on the measurement result of the third carrier.

[0427] In some embodiments, the fourth round-trip delay threshold may be a preset round-trip delay threshold or a round-trip delay threshold configured by the network device.

[0428] Condition 4.6: The spatial correlation between the cell corresponding to the third carrier and the cell corresponding to the fourth carrier is greater than or equal to the fourth spatial correlation threshold.

[0429] In some embodiments, if condition 4.6 is met, it indicates that the cell corresponding to the third carrier and the cell corresponding to the fourth carrier are highly similar or correlated in spatial location, so the measurement result of the fourth carrier can be predicted based on the measurement result of the third carrier.

[0430] In some embodiments, the fourth spatial correlation threshold may be a preset spatial correlation threshold or a spatial correlation threshold configured by the network device.

[0431] Condition 4.7: The spectral correlation between the third carrier and the fourth carrier is greater than or equal to the fourth spectral correlation threshold.

[0432] In some embodiments, if condition 4.7 is met, it indicates that the third carrier and the fourth carrier are highly similar in terms of spectral shape, frequency distribution, and energy distribution, and therefore the measurement results of the fourth carrier can be predicted based on the measurement results of the third carrier.

[0433] In some embodiments, the fourth spectrum correlation threshold may be a preset spectrum correlation threshold or a spectrum correlation threshold configured by the network device.

[0434] e. The ability of terminal equipment to predict the quality of L3 signals based solely on SSB.

[0435] In some embodiments, the network device is configured with carriers for L3 measurements based solely on SSB within the MG. These carriers for L3 measurements based on CSI-RS within the MG include a fifth carrier and a sixth carrier. The terminal device has the capability to predict the L3 signal quality based solely on SSB, and can predict the measurement results of the sixth carrier based on the measurement results of the fifth carrier.

[0436] In some embodiments, the number of fifth carriers can be one or more, and the number of sixth carriers can be one or more.

[0437] In some embodiments, at least one first carrier includes a fifth carrier, at least one second carrier includes a sixth carrier, the measurement result of the fifth carrier is used to predict the measurement result of the sixth carrier, and the fifth and sixth carriers are carriers configured for L3 measurement based solely on SSB within the MG;

[0438] The terminal device's ability to predict L3 signal quality based solely on SSB is defined as follows: Under the fifth condition, the terminal device's ability to predict L3 signal quality based solely on SSB includes at least one of the following conditions 5.1 to 5.7:

[0442] Condition 5.3: The cell corresponding to the fifth carrier and the cell corresponding to the sixth carrier have a co-location relationship.

[0443] In some embodiments, there is an overlap in coverage area between the cell corresponding to the fifth carrier and the cell corresponding to the sixth carrier, which indicates that the cell corresponding to the fifth carrier and the cell corresponding to the sixth carrier have a co-location relationship.

[0444] Condition 5.4: The power difference between the cell corresponding to the fifth carrier and the cell corresponding to the sixth carrier is less than or equal to the fifth power difference threshold.

The difference between the two values ​​is the power difference in condition 5.4. If the power difference is less than or equal to the fifth power difference threshold, the terminal device can predict the measurement result of the sixth carrier based on the measurement result of the fifth carrier.

[0446] In some embodiments, the fifth power difference threshold may be a preset power difference threshold or a power difference threshold configured by the network device.

[0447] Condition 5.5: The round-trip delay between the cell corresponding to the fifth carrier and the cell corresponding to the sixth carrier is less than or equal to the fifth round-trip delay threshold.

[0448] In some embodiments, if condition 5.5 is met, it means that the distance between the cell corresponding to the fifth carrier and the cell corresponding to the sixth carrier is small, so the measurement result of the sixth carrier can be predicted based on the measurement result of the fifth carrier.

[0449] In some embodiments, the fifth round-trip delay threshold may be a preset round-trip delay threshold or a round-trip delay threshold configured by the network device.

[0450] Condition 5.6: The spatial correlation between the cell corresponding to the fifth carrier and the cell corresponding to the sixth carrier is greater than or equal to the fifth spatial correlation threshold.

[0451] In some embodiments, if condition 5.6 is met, it indicates that the cell corresponding to the fifth carrier and the cell corresponding to the sixth carrier are highly similar or correlated in spatial location, so the measurement result of the sixth carrier can be predicted based on the measurement result of the fifth carrier.

[0452] In some embodiments, the fifth spatial correlation threshold may be a preset spatial correlation threshold or a spatial correlation threshold configured by the network device.

[0453] Condition 5.7: The spectral correlation between the fifth and sixth carriers is greater than or equal to the fifth spectral correlation threshold.

[0454] In some embodiments, if condition 5.7 is met, it indicates that the fifth carrier and the sixth carrier are highly similar in terms of spectral shape, frequency distribution, and energy distribution, and therefore the measurement results of the sixth carrier can be predicted based on the measurement results of the fifth carrier.

[0455] In some embodiments, the fifth spectrum correlation threshold may be a preset spectrum correlation threshold or a spectrum correlation threshold configured by the network device.

[0456] f. The terminal equipment's ability to predict the quality of L1 signals based on SSB.

[0457] In some embodiments, the network device is configured with carriers for SSB-based L1 measurement within the MG. The carriers for SSB-based L1 measurement within the MG include a seventh carrier and an eighth carrier. The terminal device has the capability to predict the quality of the SSB-based L1 signal and can predict the measurement result of the eighth carrier based on the measurement result of the seventh carrier.

[0458] In some embodiments, the number of seventh carriers can be one or more, and the number of eighth carriers can be one or more.

[0459] In some embodiments, at least one first carrier includes a seventh carrier, at least one second carrier includes an eighth carrier, the measurement result of the seventh carrier is used to predict the measurement result of the eighth carrier, and the seventh and eighth carriers are carriers configured for L1 measurement based on SSB within the MG;

[0460] The terminal device's predictive capability for SSB-based L1 signal quality is defined under the sixth condition, where the sixth condition includes at least one of the following conditions 6.1 to 6.7:

[0461] Condition 6.1: The frequencies of the seventh carrier and the eighth carrier are both within the same frequency band.

[0462] Condition 6.2: The frequency points of the seventh carrier and the eighth carrier are in different frequency bands.

[0463] In some embodiments, the frequency point of the seventh carrier may refer to the center frequency point of the seventh carrier, and the frequency point of the eighth carrier may refer to the center frequency point of the eighth carrier.

[0464] Condition 6.3: The cell corresponding to the seventh carrier and the cell corresponding to the eighth carrier have a co-location relationship.

[0465] In some embodiments, there is an overlap in coverage area between the cell corresponding to the seventh carrier and the cell corresponding to the eighth carrier, which indicates that the cell corresponding to the seventh carrier and the cell corresponding to the eighth carrier have a co-location relationship.

[0466] Condition 6.4: The power difference between the cell corresponding to the seventh carrier and the cell corresponding to the eighth carrier is less than or equal to the sixth power difference threshold.

[0467] In some embodiments, the terminal device can pre-measure the signal quality of the seventh and eighth carriers to obtain the RSRP value of the cell corresponding to the seventh carrier and the RSRP value of the cell corresponding to the eighth carrier, respectively. The difference between the two values ​​is the power difference in condition 6.4. If the power difference is less than or equal to the sixth power difference threshold, the terminal device can predict the measurement result of the eighth carrier based on the measurement result of the seventh carrier.

[0468] In some embodiments, the sixth power difference threshold may be a preset power difference threshold or a power difference threshold configured by the network device.

[0469] Condition 6.5: The round-trip delay between the cell corresponding to the seventh carrier and the cell corresponding to the eighth carrier is less than or equal to the sixth round-trip delay threshold.

[0470] In some embodiments, if condition 6.5 is met, it means that the distance between the cell corresponding to the seventh carrier and the cell corresponding to the eighth carrier is small, so the measurement result of the eighth carrier can be predicted based on the measurement result of the seventh carrier.

[0471] In some embodiments, the sixth round-trip delay threshold may be a preset round-trip delay threshold or a round-trip delay threshold configured by the network device.

[0472] Condition 6.6: The spatial correlation between the cell corresponding to the seventh carrier and the cell corresponding to the eighth carrier is greater than or equal to the sixth spatial correlation threshold.

[0473] In some embodiments, if condition 6.6 is met, it indicates that the cell corresponding to the seventh carrier and the cell corresponding to the eighth carrier are highly similar or correlated in spatial location, so the measurement result of the eighth carrier can be predicted based on the measurement result of the seventh carrier.

[0474] In some embodiments, the sixth spatial correlation threshold may be a preset spatial correlation threshold or a spatial correlation threshold configured by the network device.

[0475] Condition 6.7: The spectral correlation between the seventh and eighth carriers is greater than or equal to the sixth spectral correlation threshold.

[0476] In some embodiments, if condition 6.7 is met, it indicates that the seventh carrier and the eighth carrier are highly similar in terms of spectral shape, frequency distribution, and energy distribution, and therefore the measurement results of the eighth carrier can be predicted based on the measurement results of the seventh carrier.

[0477] In some embodiments, the sixth spectrum correlation threshold may be a preset spectrum correlation threshold or a spectrum correlation threshold configured by the network device.

[0478] Step S203: Send the first measurement result and the second measurement result to the network device.

[0479] After the terminal device performs signal quality measurements on at least one first carrier to obtain a first measurement result, and performs signal quality prediction on at least one second carrier to obtain a predicted second measurement result, the terminal device sends the first measurement result and the second measurement result to the network device. Correspondingly, the network device receives the first measurement result and the second measurement result.

[0480] In some embodiments, the terminal device may send a measurement report to the network device, the measurement report including a first measurement result and a second measurement result. Correspondingly, the network device receives the measurement report sent by the terminal device and obtains the first and second measurement results from the measurement report.

[0481] In some embodiments, the measurement delay corresponding to the first measurement result and the second measurement result is less than the first delay, wherein the measurement delay is the time required to obtain the first measurement result and the second measurement result, and the first delay is the time required to perform signal quality measurements on the first carrier and the second carrier. If the network device is configured to measure at least one first carrier and at least one second carrier, then the measurement delay refers to the time required for the terminal device to obtain the first measurement result and the second measurement result from the start of signal quality measurement on at least one first carrier.

[0482] In some embodiments, if the terminal device needs to perform signal quality measurements on at least one first carrier, the time required for the terminal device to obtain the first measurement result is equal to the sum of the time required for the terminal device to measure each of the first carriers. The time required for the terminal device to measure different first carriers may be the same or different. The time required for the terminal device to measure different first carriers is related to the measurement type configured for the first carrier and the corresponding measurement period.

[0483] In some embodiments, the terminal device may perform signal quality prediction on at least one second carrier to obtain a second measurement result. Since the second measurement result is obtained by signal quality prediction through an AI model, the time required for the terminal device to obtain the second measurement result can be considered to be zero.

[0484] In some embodiments, if signal quality measurements are performed on the first carrier and the second carrier, the first delay includes the time required for the terminal device to measure the first carrier and the time required for the terminal device to measure the second carrier.

[0485] In some embodiments, the first measurement result is used to predict the signal quality of at least one second carrier, and the measurement delay and the first delay satisfy the following relationship: measurement delay = first delay * [M0 / (M0+N0)], where M0 is the number of at least one first carrier and N0 is the number of at least one second carrier.

[0486] In some embodiments, at least one first carrier includes M first-type measurement carriers, and at least one second carrier includes N first-type prediction carriers. The M first-type measurement carriers and the N first-type prediction carriers are both carriers configured with signal quality measurement without MG. The measurement results of the M first-type measurement carriers are used to predict the measurement results of the N first-type prediction carriers.

[0487] In this case, the measurement delay includes a first duration required to acquire the measurement results of M type I measurement carriers and N type I prediction carriers, the first delay includes a second duration required to measure the M type I measurement carriers and N type I prediction carriers, and the first duration is related to M, N and the second duration, where M and N are both positive integers.

[0488] In some embodiments, the first duration is the product of the second duration and the first ratio, where the first ratio is M / (M+N). For example, the terminal device has a first prediction capability, which can obtain measurement results for M first-type measurement carriers by performing signal quality measurements on M first-type measurement carriers. Then, based on the measurement results of the M first-type measurement carriers, the terminal device predicts the measurement results for N first-type prediction carriers. The first ratio M / (M+N) indicates the first prediction capability.

[0489] In some embodiments, carriers for signal quality measurement without MG are configured, and their measurement periods are equal. Therefore, the time required for the terminal device to measure each first-type measurement carrier and each second-type prediction carrier is equal. Let T be the time required for the terminal device to measure one first-type measurement carrier, then the first time is M*T, and the second time is (M+N)*T, satisfying that the first time is the product of the second time and the first ratio.

[0490] In some embodiments, the first duration and the second duration satisfy the following equations (1) and (2), respectively: T1=[M1 / (M1+N1)]*T SCC_SSB +[M2 / (M2+N2)]*T Y +[M3 / (M3+N3)]*T Z (1) T2=T SCC_SSB +T Y +T Z (2)

[0491] Where T1 is the first duration, T2 is the second duration, M1 is the number of auxiliary carriers configured with SSB-based signal quality measurement among the M first-type measurement carriers, M2 is the number of carriers configured with non-MG inter-frequency signal quality measurement among the M first-type measurement carriers, M3 is the number of carriers configured with non-MG inter-system signal quality measurement among the M first-type measurement carriers, M = M1 + M2 + M3; N1 is the number of auxiliary carriers configured with SSB-based signal quality measurement among the N first-type prediction carriers, N2 is the number of carriers configured with non-MG inter-frequency signal quality measurement among the N first-type prediction carriers, N3 is the number of carriers configured with non-MG inter-system signal quality measurement among the N first-type prediction carriers, N = N1 + N2 + N3. T SCC_SSB The duration T required for the terminal device to measure (M1+N1) secondary carriers configured with SSB-based signal quality measurement Y The duration T required for a terminal device to measure the signal quality of (M2+N2) carriers configured without MG at different frequencies is given by the measurement method. Z The duration required for measuring the signal quality of (M3+N3) heterogeneous systems configured without MG for terminal equipment.

[0492] In some embodiments, at least one first carrier includes P second-type measurement carriers, and at least one second carrier includes Q second-type prediction carriers. Both the P second-type measurement carriers and the Q second-type prediction carriers are carriers configured with signal quality measurements within the MG. The measurement results of the P second-type measurement carriers are used to predict the measurement results of the Q second-type prediction carriers.

[0493] In this case, the measurement delay includes a third duration required to acquire the measurement results of P type II measurement carriers and Q type II prediction carriers, and the first delay includes a fourth duration required to measure the P type II measurement carriers and Q type II prediction carriers. The third duration is related to P, Q and the fourth duration, where P and Q are both positive integers.

[0494] In some embodiments, the third duration is the product of the fourth duration and the second ratio, where the second ratio is P / (P+Q). For example, the terminal device has a second prediction capability, which can obtain the measurement results of P second-type measurement carriers by performing signal quality measurements on P second-type measurement carriers. Then, based on the measurement results of the P second-type measurement carriers, the terminal device predicts the measurement results of Q second-type prediction carriers.

[0495] In some embodiments, the third duration and the fourth duration satisfy the following equations (3) and (4), respectively: T3=[P1 / (P1+Q1)]*T with_CRI-RS +[P2 / (P2+Q2)]*T SSB_only+[P3 / (P3+Q3)]*T L1_SSB (3) T4=T with_CRI-RS +T SSB_only +T L1_SSB (4)

[0496] Where T3 is the third duration, T4 is the fourth duration, P1 is the number of third carriers, P2 is the number of fifth carriers, P3 is the number of seventh carriers, and P = P1 + P2 + P3; Q1 is the number of fourth carriers, Q2 is the number of sixth carriers, Q3 is the number of eighth carriers, and Q = Q1 + Q2 + Q3. with_CRI-RS For the terminal device to measure (P1+Q1) carriers configured with CSI-RS-based L3 measurements within the MG, T SSB_only The duration required for the terminal device to measure (P2+Q2) carriers configured with L3 measurements based solely on SSB within the MG, T Z The duration required to measure (P3+Q3) carriers configured with SSB-based L1 measurements within the MG for the terminal device.

[0497] In some embodiments, the network device can make cell handover decisions or cell reselection decisions based on the first measurement result and the second measurement result. Taking the measurement result as the RSRP value as an example, a higher RSRP value generally indicates a stronger signal and better connection quality, so the network device can hand the terminal device to the corresponding cell based on the RSRP value. A lower RSRP value generally indicates a weaker signal and poorer connection quality, allowing the network device to measure stronger signals in neighboring cells and improve the connection performance of the terminal device.

[0498] The communication method involved in the embodiments of this disclosure may include at least one of steps S201 to S203. For example, step S201 may be implemented as a standalone embodiment, step S202+S203 may be implemented as a standalone embodiment, or step S201+S202+S203 may be implemented as a standalone embodiment, but is not limited thereto.

[0499] In some embodiments, steps S201 and S202 may be performed in a different order or simultaneously, and steps S201 and S203 may be performed in a different order or simultaneously. Steps S201 and S203 are optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0500] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.

[0501] Referring to Figure 3, Figure 3 is an exemplary interactive schematic diagram of a communication method provided according to an embodiment of the present disclosure. As shown in Figure 3, the communication method includes the following steps:

[0502] Step S301: Based on the signal quality prediction capability of the terminal device, perform signal quality measurement on at least one first carrier to obtain a first measurement result, and perform signal quality prediction on at least one second carrier to obtain a predicted second measurement result.

[0503] The signal quality prediction capability of a terminal device refers to the terminal device's ability to predict the signal quality of a carrier. If the terminal device has the signal quality prediction capability, it can predict the measurement results of another part of the carrier based on the measurement results of a part of the carrier. The measurement results of the carrier include at least one of the following: RSRP, RSRQ, and SINR of the reference signal on the carrier.

[0504] At least one first carrier and at least one second carrier are carriers configured for the network device. Since the terminal device has signal quality prediction capabilities, it only needs to perform signal quality measurement on at least one first carrier to obtain a first measurement result. Then, it performs signal quality prediction on at least one second carrier to obtain a second measurement result.

[0505] In some embodiments, the terminal device can perform signal quality prediction on at least one second carrier based on the first measurement result to obtain the predicted second measurement result. That is, all the measurement results of at least one first carrier (i.e., the first measurement result) are used to perform signal quality prediction on at least one second carrier.

[0506] In some embodiments, the terminal device may perform signal quality prediction on at least one second carrier based on the measurement results of a portion of the first carriers, thereby obtaining a predicted second measurement result. That is, only a portion of the measurement results of the first carriers is used to perform signal quality prediction on at least one second carrier.

[0507] In some embodiments, the signal quality prediction capability of the terminal device can be indicated by at least one of the following: the number of at least one first carrier, the number of at least one second carrier, the ratio of the number of at least one first carrier to the number of at least one second carrier, the ratio of the number of at least one first carrier to the total number of carriers, and the ratio of the number of at least one second carrier to the total number of carriers, wherein the total number of carriers is the sum of the number of at least one first carrier and the number of at least one second carrier.

[0508] In some embodiments, the terminal device may pre-send the signal quality prediction capability to the network device. Based on the signal quality prediction capability, the network device can configure time-frequency domain resources for at least one first carrier without configuring time-frequency domain resources for at least one second carrier. Then, based on the time-frequency domain resources configured for at least one first carrier, the terminal device performs signal quality measurements on at least one first carrier to obtain a first measurement result, and performs signal quality prediction on at least one second carrier to obtain a predicted second measurement result.

[0509] Step S302: Send the first measurement result and the second measurement result to the network device.

[0510] After obtaining the first and second measurement results, the terminal device completes the measurement / prediction of all carriers. Therefore, the terminal device sends the first and second measurement results to the network device. The time required for the terminal device to acquire the first and second measurement results is the measurement delay of the terminal device. This measurement delay is mainly determined by the time required for the terminal device to perform signal quality measurements on at least one first carrier. Since the terminal device does not need to perform signal quality measurements on at least one second carrier, but obtains the second measurement result through signal quality prediction, the time required for the terminal device to acquire the second measurement result is very small and can be ignored. Therefore, the measurement delay of the terminal device is less than the time required for the terminal device to perform signal quality measurements on at least one first carrier and at least one second carrier.

[0511] In some embodiments, the first measurement result and the second measurement result can be carried in a measurement report. That is, the terminal device sends a measurement report to the network device, and the measurement report includes the first measurement result and the second measurement result.

[0512] This disclosure also proposes an apparatus (also referred to as a communication device, etc.) for implementing any of the above methods. For example, an apparatus is proposed that includes units or modules for implementing the steps performed by the terminal device in any of the above methods. Furthermore, another apparatus is proposed that includes units or modules for implementing the steps performed by the network device (e.g., access network device, core network functional node, core network device, etc.) in any of the above methods.

[0513] It should be understood that the division of units or modules in the above device is only a logical functional division. In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units or modules in the device can be implemented by a processor calling software: for example, the device includes a processor connected to a memory containing instructions. The processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of the units or modules in the above device. The processor can be, for example, a general-purpose processor, such as a Central Processing Unit (CPU) or a microprocessor, and the memory can be internal or external to the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits. The functionality of some or all of the units or modules can be achieved through the design of these hardware circuits, which can be understood as one or more processors. For example, in one implementation, the hardware circuit is an application-specific integrated circuit (ASIC). The functionality of some or all of the units or modules is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a programmable logic device (PLD). Taking a field-programmable gate array (FPGA) as an example, it can include a large number of logic gates. The connection relationships between the logic gates are configured through configuration files, thereby achieving the functionality of some or all of the units or modules. All units or modules of the above device can be implemented entirely through processor-called software, entirely through hardware circuits, or partially through processor-called software with the remaining parts implemented through hardware circuits.

[0514] In this embodiment, the processor is a circuit with signal processing capabilities. In one implementation, the processor can be a circuit with instruction read and execute capabilities, such as a Central Processing Unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. The logical relationships of the aforementioned hardware circuits are fixed or reconfigurable.
