[0050] Figure 1The block diagram of a wireless communication system to which the embodiments of the present application can be applied is shown. The wireless communication system includes a terminal 11 and a network-side device 12.

As long as the same technical effect is achieved, the base station is not limited to a specific technical term. It should be noted that in the embodiments of this application, only the base station in the NR system is taken as an example for introduction, and the specific type of the base station is not limited.

[0051] To facilitate a clearer understanding of the technical solutions provided by the embodiments of this application, some related knowledge is introduced as follows.

[0052] Traditional Radio Resource Management (RRM) measurements include Layer 3 (L3) measurements and Layer 1 (L1) measurements. The UE needs to report the L3 results to the base station based on the L3 measurements. Then, based on the L3 measurement results, the base station indicates and achieves cell changes (here, generally referring to handover, redirection, secondary cell addition / activation, primary-secondary cell addition / activation, etc.). During or after this process, the base station can, as needed, further issue an L1 measurement configuration on this cell to instruct the UE to perform L1 measurements. Traditionally, L1 measurements are mainly used for beam management.

[0053] Due to the existence of massive antenna array technology in the 5rd Generation Mobile Communication (5G), operations such as beam management are defined in the 5G standard. The network needs to configure the UE to perform L1 measurements and determine the optimal uplink and downlink beam pairing based on the L1 reports after the UE completes the measurements, so as to achieve the theoretical limit performance. To a certain extent, this process makes it necessary for the network and the UE to conduct multiple rounds of information collection and interaction during the cell change process to reach the theoretical performance limit. Such multiple rounds of information collection and interaction often require a relatively long time. Therefore, when the UE switches frequently in the medium and high-speed mobile state, the UE often fails to reach the limit performance in most of the cells it experiences, resulting in losses in spectral efficiency and user experience.

[0054] To shorten the information interaction duration between the base station and the UE, a key means to improve performance is to establish a link with the target cell in advance before the handover, that is, to complete the beam management process in advance and minimize the interruption of real-time communication with the source cell during this process.

[0055] When the system configures L1 measurements for the target cell, similar to L3 measurements, the system may further configure L1 measurements for intra-frequency or inter-frequency deactivated SCell. If the configured L1 measurement is outside the current activated (Bandwidth Part, BWP), the UE needs a measurement gap to perform the configured L1 measurement. Generally, the system will configure multiple measurement objects for the UE, and some of the measurement objects that require a measurement gap need to share the measurement gap configured by the system.

[0056] For the scenario where both L1 and L3 measurements are configured for a certain deactivated Scell, the corresponding L3 measurement requirements can follow the current L3 measurement performance indicators of the deactivated SCell. However, due to the existence of L1 measurements, the current L3 performance measurement indicators can be greatly optimized. At the same time, the measurement requirements for L1 also need to be clearly defined.

[0057] For a deactivated SCell, if L1 and L3 measurements are both configured, for the L3 measurement, according to the current performance metrics, the measurement delay is relatively large; since the L1 measurement is configured, frequent L1 measurements prevent the terminal from entering deep sleep, resulting in a relatively low power saving gain for the terminal. Therefore, a new measurement method is needed to solve this problem. At the same time, using the new method to reduce the delay will also have an impact on the terminal interruption, and corresponding solutions are also required. Based on the new method, the performance metrics for the L1 measurement of the deactivated SCell also need to be determined.

[0058] The following will, in conjunction with the accompanying drawings, through some embodiments and their application scenarios, elaborate on the SCell measurement methods, apparatuses, terminals, and network-side devices provided by the embodiments of the present application.

[0059] Figure 2 is one of the flow diagrams of the SCell measurement method provided by the embodiments of the present application. This method is applied to a terminal, such as Figure 2 shown. This method includes step 201 and step 202, where:

[0060] Step 201: The terminal performs an L1 measurement on the first frequency point of the first SCell;

[0061] Step 202: The terminal performs an L3 measurement on the second frequency point of the first SCell;

[0062] wherein, the first frequency point and the second frequency point are respectively associated with the same target physical frequency point of the first SCell, and the target physical frequency point is configured with both L1 measurement and L3 measurement.

[0063] Optionally, the first SCell may include at least one of the following: a deactivated SCell; a dormant SCell; a specific SCell.

[0064] For example, in the case where the first SCell is in a deactivated state or a dormant state, if the same target physical frequency point of the first SCell is configured with both L1 measurement and L3 measurement, for this target physical frequency point, in the embodiments of the present application, L1 is used as the first frequency point of the first SCell, L3 is used as the second frequency point of the first SCell, and the first frequency point and the second frequency point are both associated with the target physical frequency point, that is, L1 and L3 are respectively treated as a logical frequency point. The terminal performs an L1 measurement on the first frequency point and an L3 measurement on the second frequency point.

[0065] Optionally, the network-side device sends configuration information to the terminal, and the configuration information includes at least one of the following:

[0066] 1) The first frequency point for the L1 measurement;

[0067] 2) The second frequency point for the L3 measurement;

[0068] Optionally, the configuration information further includes: indication information for indicating that the first frequency point and the second frequency point are respectively associated with the target physical frequency point.

[0069] After the terminal receives the configuration information from the network-side device, based on the configuration information, the terminal performs L1 measurement on the first frequency point of the first Scell and performs L3 measurement on the second frequency point of the first Scell.

[0070] In an embodiment of the present application, the same target physical frequency point of the first Scell is simultaneously configured with L1 measurement and L3 measurement. For this target physical frequency point, L1 is used as the first frequency point of the first Scell, L3 is used as the second frequency point of the first Scell, and both the first frequency point and the second frequency point are associated with the target physical frequency point, that is, L1 and L3 are respectively treated as a logical frequency point. The terminal performs L1 measurement on the first frequency point and performs L3 measurement on the second frequency point, so as to implement L1 measurement and L3 measurement on the first SCell that is simultaneously configured with L1 and L3 measurements.

[0071] Optionally, the terminal receives a measurement request from the network-side device, and the measurement request instructs the terminal to perform the L1 measurement and the L3 measurement. Then, the terminal triggers the L1 measurement and the L3 measurement based on the measurement request.

[0072] Optionally, the terminal reports the L1 measurement result to the network-side device based on the L1 measurement; the terminal reports the L3 measurement result to the network-side device based on the L3 measurement.

[0073] Optionally, the performance index of the L1 measurement includes a first scaling factor; and / or, the performance index of the L3 measurement includes a second scaling factor.

[0074] In order to determine the longest measurement time of the L1 measurement and the longest measurement time of the L3 measurement, first calculate the first scaling factor of the L1 measurement performance index and the second scaling factor in the L3 measurement performance index. Then, determine the longest measurement time of the L1 measurement based on the first scaling factor, and determine the longest measurement time of the L3 measurement based on the second scaling factor.

[0075] The longest measurement time refers to the maximum time allowed for the terminal to complete the L1 / L3 measurement of the corresponding frequency point for cell discovery and cell measurement. It is a boundary condition that the relevant measurement process module needs to consider during internal processing. It should be noted that the terminal does not always complete the corresponding measurement according to the longest measurement time. That is to say, the terminal can complete the measurement in advance.

[0076] Optionally, the first scaling factor and the second scaling factor are determined according to at least one of the following:

[0077] Case 1: For the case where gap measurement is required for the L1 frequency point (i.e., the first frequency point) and no gap measurement is required for the L3 frequency point (i.e., the second frequency point): The first scaling factor is determined according to the Carrier-Specific Scaling Factor (CSSF) (CSSF within_gap,i ) within the gap; the second scaling factor is determined according to the CSSF (CSSF outside_gap,i ) outside the gap. Here, i represents a certain measurement object (MO).

[0078] The longest measurement time for L1 / L3 measurement is calculated as follows: The first scaling factor of the L1 measurement performance index is calculated in the CSSF within_gap,i . The second scaling factor in the L3 measurement performance index is considered in the CSSF outside_gap,i . Then, the longest measurement time for L1 measurement is determined based on the first scaling factor, and the longest measurement time for L3 measurement is determined based on the second scaling factor.

[0079] Case 2: For the case where no gap measurement is required for the L1 frequency point (i.e., the first frequency point) and gap measurement is required for the L3 frequency point (i.e., the second frequency point): The first scaling factor is determined according to the CSSF outside_gap,i , and the second scaling factor is determined according to the CSSF within_gap,i .

[0080] Case 3: For the case where gap measurement is required for both the L1 frequency point (i.e., the first frequency point) and the L3 frequency point (i.e., the second frequency point): The first scaling factor is determined according to the CSSF within_gap,i , and the second scaling factor is determined according to the CSSF within_gap,i .

[0081] The longest measurement time for L1 / L3 measurement is calculated as follows: The first scaling factor of the L1 measurement performance index is determined according to the CSSF within_gap,i , and the second scaling factor in the L3 measurement performance index is determined according to the CSSF within_gap,i . Then, the longest measurement time for L1 measurement is determined based on the first scaling factor, and the longest measurement time for L3 measurement is determined based on the second scaling factor.

[0082] If the reference signal periods of the L1 measurement and the L3 measurement are exactly the same, then when calculating the CSSF within_gap,i they can be combined, that is, regarded as a single frequency layer for calculation. In this scenario, for Frequency Range 2 (FR2), time-division measurements of the L3 measurement and the L1 measurement need to be performed. When determining the longest measurement time, the time-division sharing measurement factor between L1 and L3 also needs to be considered.

[0083] Case 4: For the case where neither the L1 frequency point (i.e., the first frequency point) nor the L3 frequency point (i.e., the second frequency point) requires gap measurement: The first scaling factor is determined according to the CSSF outside_gap,i and the second scaling factor is determined according to the CSSF outside_gap,i

[0084] Optionally, for a certain deactivated SCell frequency point, if this frequency point is configured with both inter-frequency L1 and inter-frequency L3 measurements, L1 and L3 are each treated as a (logical) frequency point; for the case where L1 requires a gap for measurement, L3 can be measured either within or outside the gap at this time. The first scaling factor is determined according to the CSSF within_gap,i and the L1 measurement is used as a candidate for measurement within the target gap, that is, the L1 measurement needs to be added to the candidates for using this target gap.

[0085] Optionally, for the case where the L1 frequency point does not require a gap for measurement, L3 can be measured either within or outside the gap at this time. The first scaling factor is determined according to the CSSF outside the gap, and the L1 measurement is used as a candidate for measurement outside the target gap. Considering the L1 measurement in the CSSF outside_gap,i can be as follows for example:

[0086] For the case where the inter-frequency L1 measurement does not require a gap for measurement, the CSSF outside_gap,i can be calculated using the following formula:

[0087] 1) For the scenario of Frequency Range 1 carrier aggregation (FR1 only CA), CSSF outside_gap,i = N SCC_SSB + Y + 2xN SCC_CSIRS+ N SCC_L1

[0088] 2) For the scenario of FR2 intra-band carrier aggregation (FR2 only intra band CA), CSSF outside_gap,i = N SCC_SSB + Y + 2x N SCC_CSIRS+ N SCC_L1 ​

[0089] 3) For the scenario of FR2 only inter band CA, CSSF outside_gap,i = 2×(N SCC_SSB + Y + 2x N SCC_CSIRS - 1 - N SCC_CSIRS_FR2_NCM ) + N SCC_L1

[0090] 4) For the scenario of FR1+FR2 CA (FR1 Primary cell (Pcell)), CSSF outside_gap,i = 2×(N SCC_SSB + Y + 2x N SCC_CSIRS - 1 - N SCC_CSIRS_FR2_NCM ) + N SCC_L1

[0091] 5) For the scenario of FR1+FR2 CA (FR2 PCell), CSSF outside_gap,i = N SCC_SSB + Y + 2x N SCC_CSIRS+ N SCC_L1 。

[0092] Where, N SCC_L1 is the number of inter-frequency L1 measurements outside the gap (e.g., the number of configured inter-frequency L1 measurement without MG that are being measured outside of MG);

[0093] N SCC_SSB is the number of SCell(s) with SSB-based L3 measurement configured, (e.g., Number of configured SCell(s) with only SSB based L3 measurement configured, which is measured without MG);

[0094] Y is the number of configured inter-frequency measurement objects (MOs) outside the gap (e.g., the number of configured inter-frequency MOs without MG that are being measured outside of MG; otherwise, it is 0);

[0095] N SCC_CSIRSThe number of SCell(s) configured with either both SSB and CSI-RS based L3 measurement or only CSI-RS based L3 measurement (e.g., Number of configured SCell(s) with either both SSB and CSI-RS based L3 measurement configured or only CSI-RS based L3 measurement configured);

[0096] N SCC_CSIRS_FR2_NCM Is equal to 1 if FR2 Secondary Component Carrier (SCC), where neighbour cell measurement is required, is configured with both SSB and CSI-RS or only CSI-RS measurement; otherwise, N SCC_CSIRS_FR2_NCM = 0).

[0097] Optionally, the gap used for the L1 measurement and / or L3 measurement is mainly the network controlled small gap (NCSG). For the L1 measurement, or whether a gap is required when both L1 measurement and L3 measurement are configured, the terminal can report its capabilities to inform the network device.

[0098] The terminal sends capability information to the network device; wherein, the capability information includes at least one of the following:

[0099] 1) A gap is required for the L1 measurement.

[0100] It should be noted that 'a gap is required for the L1 measurement' means that for the L1 measurement, the terminal reports its capabilities to the frequency layer of the first SCell, indicating that the terminal needs the network to configure the corresponding gap when performing deactivation / sleep of the SCell or L1 measurement of the neighbouring cell.

[0101] 2) A network controlled small gap (NCSG) is required for the L1 measurement.

[0102] 3) A gap is not required for the L1 measurement.

[0103] It should be noted that the statement 'L1 measurement does not require a gap' means that for L1 measurement, the terminal reports its capability information to the frequency layer of the first SCell, indicating that the terminal does not require a measurement gap when performing deactivation / sleep of the SCell or L1 measurement of neighboring cells. For example, the terminal reports "nogap-noncsg" through NeedforNCSG.

[0104] Optionally, when 'L1 measurement does not require a gap', the terminal may also not report the capability information, implicitly indicating that the terminal does not require a measurement gap when performing deactivation / sleep of the SCell or L1 measurement of neighboring cells.

[0105] 4) L3 measurement requires a gap.

[0106] 5) L3 measurement requires NCSG.

[0107] 6) L3 measurement does not require a gap.

[0108] It should be noted that the statement 'L3 measurement does not require a gap' means that for L3 measurement, the terminal reports its capability information to the frequency layer of the first SCell, indicating that the terminal does not require a measurement gap when performing deactivation / sleep of the SCell or L3 measurement of neighboring cells. For example, the terminal reports "nogap-noncsg" through NeedforNCSG.

[0109] Optionally, the capability information occupies one information field, indicating that both L1 measurement and L3 measurement satisfy any one of the following: require a gap, require NCSG, or do not require a gap. That is, the requirement for a gap in both L1 measurement and L3 measurement (both require a gap, both require NCSG, or both do not require a gap) is indicated through 1 field.

[0110] Alternatively, the capability information occupies two information fields, respectively indicating whether L1 measurement and L3 measurement require a gap.

[0111] For example, if for the L1 measurement and L3 measurement of the deactivated SCell, two fields are used to respectively indicate whether L1 measurement and L3 measurement require a gap, the signaling can be as follows:

[0130] In the prior art, the determination of the longest measurement time for deactivating the L3 measurement of the first SCell depends on the value of the measurement period (measCycleSCell). The purpose of introducing it is to give the terminal relatively sufficient time so that the terminal can enter (deep) sleep during the measurements of 2 deactivated SCells. The design idea is to exchange a longer measurement delay for power saving of the terminal. However, if L1 measurement is configured for the deactivated SCell and the L1 measurement generally needs to be performed more frequently to achieve the purpose of timely handover, therefore, the terminal cannot enter deep sleep.

[0131] To solve this problem, in the SCell measurement method provided by the embodiments of the present application, in case 4, when no gap measurement is required for both the L1 frequency point (i.e., the first frequency point) and the L3 frequency point (i.e., the second frequency point) of the first SCell, if L1 measurement is configured or activated on the SSB frequency layer for deactivating the first SCell, the longest measurement time of the L3 measurement and the L1 measurement can be determined according to the synchronization signal / physical broadcast channel block (SSB) period of L1 or L3 or the radio resource management measurement timing configuration (SMTC) period based on SSB, rather than being determined according to the configured MeasCycleScell of L3. In this way, the L3 measurement delay of the deactivated SCell can be greatly reduced.

[0132] Optionally, a. The performance index of the L1 measurement is determined according to the SSB period of the measurement object, and the performance index of the L3 measurement is determined according to the SMTC period of the measurement object;

[0133] Or, b. The performance indexes of both the L1 measurement and the L3 measurement are determined according to the SSB period of the measurement object. For the serving cell and the neighboring cell that needs to perform L1 measurement, the SSB periods are always equal.

[0134] Optionally, if for a certain deactivated SCell frequency point, neither the configured L1 nor L3 requires gap measurement, the measurement time and related performance indexes of L3 and L1 are determined according to the SSB.

[0135] In the prior art, the performance metrics of deactivated SCell L3 measurements are shown in Table 1 and depend on the value of measCycleSCell. measCycleSCell is a system configuration used to control the measurement delay for power saving of the terminal.

[0136] Table 1 Time period

[0137]

[0138] Among them, T PSS / SSS_sync_intra represents the detection time of the same-frequency PSS / SSS (synchronization signal) in the synchronization state; Ceil is the ceil function; K p represents the scaling factor of the SSB frequency points to be measured without measurement gaps; CSSF intra represents the same-frequency specific carrier scaling factor.

[0139] In the Scell measurement method provided by the embodiments of the present application, the deactivated SCell L3 measurement can be performed based on the SSB (instead of measCycleSCell), achieving the purpose of reducing the deactivated SCell L3 measurement delay. The relevant performance metrics can use the SSB of the measurement object to replace measCycleSCell, as shown in Table 2, where T SSB is the SSB period of the measurement object.

[0140] Table 2 Time period

[0141]

[0142] Optionally, the embodiments of the present application provide a method for determining the interruption caused by measurement when simultaneously configuring L1 / L3 measurements for deactivated SCell:

[0143] If, for a certain deactivated SCell frequency point, when simultaneously configuring L1 / L3 measurements, the performance metrics of the L1 measurement are determined according to the SSB period of the measurement object, and the performance metrics of the L3 measurement are determined according to the SMTC period of the measurement object; or, when the performance metrics of the L1 measurement and the L3 measurement are both determined according to the SSB period of the measurement object, the interruption of the L1 / L3 measurement is determined as follows:

[0144] The L1 measurement and the L3 measurement satisfy at least one of the following:

[0145] 1) The network does not configure the measurement period of the first Scell, and neither the L1 measurement nor the L3 measurement generates an interruption.

[0146] For example, when the system does not configure measCycleSCell, neither the L1 measurement nor the L3 measurement generates an interruption, improving the system throughput.

[0147] 2) The network configures the measurement period of the first SCell, and neither the L1 measurement nor the L3 measurement generates an interruption.

[0148] For example, when the system still configures measCycleSCell, due to using the method a or b above, the L3 measurement period does not depend on measCycleSCell. Therefore, even if measCycleSCell >= 640 ms, the L3 measurement does not cause an interruption. At this time, the L1 measurement also does not cause an interruption, improving the system throughput.

[0149] That is to say, if for a certain deactivated SCell frequency point, when both L1 and L3 are configured and no gap measurement is required, the L3 and L1 measurements can be based on the SSB; or the L1 measurement uses the SSB period and the L3 measurement uses the SMTC period. At this time, regardless of whether the system configures measCycleSCell, since the SSB or SMTC value will be less than 640 ms, it can be required that the L1 and L3 measurements of the deactivated SCell do not cause an interruption.
