As long as the same technical effect is achieved, the base station is not limited to specific technical vocabulary. It should be noted that in the embodiment of the present application, only the base station in the NR system is used as an example for introduction, and the specific type of the base station is not limited.

[0053] In order to facilitate a clearer understanding of the technical solutions provided by the embodiments of the present application, some relevant knowledge is first introduced as follows.

[0054] Traditional Radio Resource Management (RRM) measurements include Layer 3 (L3) and Layer 1 (L1) measurements. Based on the L3 measurements, the UE reports the L3 results to the base station. The base station then instructs and implements cell changes (generally referring to handover, redirection, secondary cell loading / activation, primary / secondary cell loading / activation, etc.) based on the L3 measurement results. During or after this process, the base station can, as needed, further issue L1 measurement configurations on the cell, instructing the UE to perform L1 measurements. Traditionally, L1 measurements are primarily used for beam management.

[0055] Due to the presence of large-scale antenna array technology in the 5th Generation Mobile Communication (5G), the 5G standard defines operations such as beam management. The network needs to configure the UE to perform L1 measurements and determine the optimal uplink and downlink beam pairing based on the L1 report after the UE completes the measurement, thereby achieving the theoretical performance limit. This process, to a certain extent, requires multiple rounds of information collection and interaction between the network and the UE during the cell change process to achieve the theoretical performance limit. Such multiple rounds of information collection and interaction often take a relatively long time. Therefore, when the UE switches frequently in a medium-to-high-speed mobile state, the UE often cannot achieve the maximum performance in most of the cells it passes through, resulting in a loss of spectrum efficiency and a loss of user experience.

[0056] In order to shorten the information exchange time between the base station and the UE and improve performance, a key means is to establish a link with the target cell in advance before switching, that is, to complete the beam management process in advance and minimize the interruption of real-time communication in the source cell during this process.

[0057] When the system configures L1 measurements for the target cell, similar to L3 measurements, the system may further configure L1 measurements for deactivated SCells (intra-frequency or inter-frequency). If the configured L1 measurement is outside the currently activated Bandwidth Part (BWP), the UE requires a measurement gap to perform the configured L1 measurement. Generally, the system configures multiple measurement objects for the UE, some of which require measurement gaps and need to share the system-configured measurement gaps.

[0058] In scenarios where both L1 and L3 measurements are configured for a deactivated Scell, the corresponding L3 measurement requirements can follow the current deactivated SCell L3 measurement performance indicators. However, due to the presence of L1 measurements, the current L3 performance measurement indicators can be significantly optimized. At the same time, the L1 measurement requirements also need to be clearly defined.

[0059] For deactivated SCells, if both L1 and L3 measurements are configured, the current performance metrics for L3 measurements show significant measurement latency. Furthermore, frequent L1 measurements prevent the terminal from entering deep sleep, resulting in lower power savings. Therefore, a new measurement method is needed to address this issue. However, while this new method reduces latency, it also impacts terminal outages, requiring a corresponding solution. Based on this new method, performance metrics for L1 measurements on deactivated SCells also need to be determined.

[0060] The Scell ​​measurement method, apparatus, terminal, and network-side equipment provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings through some embodiments and their application scenarios.

[0061] FIG2 is a flow chart of a Scell ​​measurement method according to an embodiment of the present application. The method is applied to a terminal. As shown in FIG2 , the method includes steps 201 and 202, wherein:

[0062] Step 201: A terminal performs L1 measurement on a first frequency point of a first Scell.

[0063] Step 202: The terminal performs L3 measurement on the second frequency of the first Scell.

[0064] 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.

[0065] Optionally, the first Scell ​​may include at least one of the following: a deactivated Scell; a dormant Scell; or a specific Scell.

[0066] For example, when a first Scell ​​is in a deactivated state or a dormant state, if both L1 measurement and L3 measurement are configured for the same target physical frequency of the first Scell, for the target physical frequency, in this embodiment of the present application, L1 is used as the first frequency of the first Scell ​​and L3 is used as the second frequency of the first Scell. Both the first frequency and the second frequency are associated with the target physical frequency, that is, L1 and L3 are each processed as a single logical frequency. The terminal performs L1 measurement on the first frequency and L3 measurement on the second frequency.

[0067] Optionally, the network-side device sends configuration information to the terminal, where the configuration information includes at least one of the following:

[0068] 1) the first frequency point used for the L1 measurement;

[0069] 2) the second frequency point used for the L3 measurement;

[0070] Optionally, the configuration information further includes: indication information, which is used to indicate that the first frequency point and the second frequency point are respectively associated with the target physical frequency point.

[0071] After receiving the configuration information from the network-side device, the terminal performs L1 measurement on the first frequency of the first Scell ​​and performs L3 measurement on the second frequency of the first Scell ​​based on the configuration information.

[0072] In an embodiment of the present application, the same target physical frequency of the first Scell ​​is configured with L1 measurement and L3 measurement at the same time. For the target physical frequency, L1 is used as the first frequency of the first Scell, and L3 is used as the second frequency of the first Scell, and both the first frequency and the second frequency are associated with the target physical frequency, that is, L1 and L3 are respectively processed as a logical frequency. The terminal performs L1 measurement on the first frequency and L3 measurement on the second frequency, thereby realizing L1 measurement and L3 measurement of the first SCell for which L1 and L3 measurements are simultaneously configured.

[0073] Optionally, the terminal receives a measurement request from a network-side device, the measurement request instructing 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.

[0074] Optionally, the terminal reports an L1 measurement result to a network-side device based on the L1 measurement; and the terminal reports an L3 measurement result to a network-side device based on the L3 measurement.

[0075] Optionally, the performance indicator of the L1 measurement includes a first scaling factor; and / or the performance indicator of the L3 measurement includes a second scaling factor.

[0076] To determine the maximum measurement time for L1 and L3 measurements, a first scaling factor for the L1 and L3 performance indicators is calculated. The maximum measurement time for L1 and L3 measurements is then determined based on the first scaling factor and the second scaling factor, respectively.

[0077] The maximum measurement time is the maximum time allowed for a terminal to complete cell discovery and measurement when performing L1 / L3 measurements on the corresponding frequency. It is a boundary condition that the relevant measurement process processing module must consider during internal processing. It should be noted that the terminal does not always complete the corresponding measurement within the maximum measurement time; in other words, the terminal can complete the measurement early.

[0078] Optionally, the first scaling factor and the second scaling factor are determined according to at least one of the following:

[0079] Case 1: For the case where gap measurement is required for L1 frequency (i.e., the first frequency), but gap measurement is not required for L3 frequency (i.e., the second frequency): the first scaling factor is based on the carrier-specific scaling factor (CSSF) in the gap. within_gap,i ) is determined; the second scaling factor is determined according to the gap outside CSSF (CSSF outside_gap,i ) is determined. Here, i represents a measurement object (MO).

[0080] The maximum measurement time for L1 / L3 measurements is calculated as follows: The first scaling factor for the L1 measurement performance indicator is in CSSF within_gap,i The second scaling factor in the L3 measurement performance indicator is calculated in CSSF outside_gap,i Then, the longest measurement time of the L1 measurement is determined based on the first scaling factor, and the longest measurement time of the L3 measurement is determined based on the second scaling factor.

[0081] Case 2: For the L1 frequency point (i.e., the first frequency point), gap measurement is not required, but the L3 frequency point (i.e., the second frequency point) requires gap measurement: the first scaling factor is based on the CSSF outside_gap,i Determine the second scaling factor according to CSSF within_gap,i Sure.

[0082] Case 3: For the case where both L1 frequency point (i.e., the first frequency point) and L3 frequency point (i.e., the second frequency point) need gap measurement: the first scaling factor is based on CSSF within_gap,i Determine the second scaling factor according to CSSF within_gap,i Sure.

[0083] The maximum measurement time for L1 / L3 measurements is calculated as follows: The first scaling factor for the L1 measurement performance indicator is calculated based on the CSSF within_gap,i Determine that the second scaling factor in the L3 measurement performance indicator is based on the CSSF within_gap,i Then, a maximum measurement time of the L1 measurement is determined based on the first scaling factor, and a maximum measurement time of the L3 measurement is determined based on the second scaling factor.

[0084] If the reference signal periods of L1 and L3 measurements are exactly the same, then both will be used in calculating CSSF. within_gap,i In this scenario, for frequency range 2 (FR2), L3 measurements and L1 measurements must be time-shared. The time-shared measurement factor between L1 and L3 must also be considered when determining the maximum measurement time.

[0085] Case 4: For the case where both L1 frequency point (i.e., the first frequency point) and L3 frequency point (i.e., the second frequency point) do not require gap measurement: the first scaling factor is based on CSSF outside_gap,i Determine the second scaling factor according to CSSF outside_gap,i Sure.

[0086] Optionally, for a deactivated SCell frequency, if both inter-frequency L1 and inter-frequency L3 measurements are configured for that frequency, L1 and L3 are treated as one (logical) frequency. For L1 that requires a gap for measurement, L3 can be measured inside or outside the gap, and the first scaling factor is based on the CSSF. within_gap,i It is determined that the L1 measurement is a candidate for measurement within the target gap, that is, the L1 measurement needs to be added to the candidate objects using the target gap.

[0087] Optionally, in the case where the L1 frequency point does not require gap measurement, L3 can be measured inside or outside the gap, the first scaling factor is determined according to the gap outside CSSF, and the L1 measurement is used as a candidate for the target gap outside measurement. outside_gap,i Considering L1 measurement, the specific example is as follows:

[0088] For inter-frequency L1 measurement without gap measurement, CSSF outside_gap,i It can be calculated using the following formula:

[0089] 1) For the frequency range 1 carrier aggregation (FR1 only CA) scenario, CSSF outside_gap,i =N SCC_SSB +Y+2xN SCC_CSIRS+ N SCC_L1

[0090] 2) For the FR2 only intra band CA scenario, CSSF outside_gap,i =N SCC_SSB +Y+2x N SCC_CSIRS+ N SCC_L1

[0091] 3) For the FR2 only inter band CA scenario, CSSF outside_gap,i =2×(N SCC_SSB +Y+2x N SCC_CSIRS -1-N SCC_CSIRS_FR2_NCM ) + N SCC_L1

[0092] 4) For FR1+FR2 CA (FR1 Primary cell (Pcell) scenario, CSSF outside_gap,i =2×(N SCC_SSB +Y+2x N SCC_CSIRS -1-N SCC_CSIRS_FR2_NCM ) + N SCC_L1

[0093] 5) For FR1+FR2 CA (FR2 PCell) scenarios, CSSF outside_gap,i =N SCC_SSB +Y+2x N SCC_CSIRS+ N SCC_L1 .

[0094] Among them, N SCC_L1 The number of gap inter-frequency L1 measurements (e.g. the number of configured inter-frequency L1 measurements without MG that are being measured outside of MG);

[0095] N SCC_SSB The number of SCells configured with SSB-based L3 measurement (e.g., Number of configured SCell(s) with only SSB-based L3 measurement configured, which is measured without MG);

[0096] Y is the number of inter-frequency measurement objects (MO) measured 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);

[0097] N SCC_CSIRSThe number of SCells configured with either SSB-based and CSI-RS-based L3 measurement or only CSI-RS-based L3 measurement configured (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);

[0098] N SCC_CSIRS_FR2_NCM Equal to 1 if FR2 SCC (where neighbor cell measurement is required), is with either both SSB and CSI-RS configured or only CSI-RS measurement configured; otherwise, N SCC_CSIRS_FR2_NCM =0).

[0099] Optionally, the gap used in the L1 measurement and / or L3 measurement is mainly a network controlled small gap (NCSG). For L1 measurement, or when configuring both L1 measurement and L3 measurement, whether a gap is required can be notified to the network side device by means of capability reporting.

[0100] The terminal sends capability information to the network device; wherein the capability information includes at least one of the following:

[0101] 1) L1 measurement requires a gap.

[0102] It should be noted that 'L1 measurement requires gap' means that for L1 measurement, the terminal reports capability information to the frequency layer of the first Scell, indicating that the network needs to configure a corresponding gap when the terminal performs L1 measurement of a deactivated / dormant SCell or a neighboring cell.

[0103] 2) L1 measurement requires network control small gap NCSG.

[0104] 3) No gap is required for L1 measurement.

[0105] It should be noted that "no gap required for L1 measurement" means that for L1 measurement, the terminal reports capability information to the frequency layer of the first Scell, indicating that the terminal does not need to measure gaps when performing L1 measurement on deactivated / dormant SCells or neighboring cells. For example, the terminal reports "nogap-noncsg" through NeedforNCSG.

[0106] Optionally, when 'L1 measurement does not require a gap', the terminal may not report capability information, implicitly indicating that the terminal does not need to measure a gap when performing L1 measurement of a deactivated / sleep SCell or a neighboring cell.

[0107] 4) L3 measurement requires a gap.

[0108] 5) L3 measurement requires NCSG.

[0109] 6) No gap is required for L3 measurement.

[0110] It should be noted that "no gap required for L3 measurement" means that for L3 measurement, the terminal reports capability information to the frequency layer of the first Scell, indicating that the terminal does not need to measure gaps when performing L3 measurements on deactivated / dormant SCells or neighboring cells. For example, the terminal reports "nogap-noncsg" through the NeedforNCSG message.

[0111] Optionally, the capability information occupies one information field, indicating that L1 measurement and L3 measurement simultaneously meet any of the following requirements: gap requirement, NCSG requirement, or gap requirement. That is, the gap requirement for L1 measurement and L3 measurement (gap requirement, NCSG requirement, or gap requirement) is simultaneously indicated through one field.

[0112] Alternatively, the capability information occupies two information fields, respectively indicating whether L1 measurement and L3 measurement require a gap.

[0113] For example, if two fields are used to indicate whether a gap is required for L1 measurement and L3 measurement for deactivated SCell, the signaling may be as follows:

[0114] In the prior art, the maximum measurement time for L3 measurements of the first deactivated Scell ​​is determined by the value of the measurement cycle (measCycleSCell). This is introduced to provide the terminal with sufficient time to enter (deep) sleep between two deactivated SCell measurements. The design concept is to trade a longer measurement delay for terminal power savings. However, if L1 measurements are configured for the deactivated Scell, and L1 measurements generally require frequent execution to achieve timely handover, the terminal cannot enter deep sleep.

[0115] In order to solve this problem, in the Scell ​​measurement method provided in an embodiment of the present application, in situation 4, when no gap measurement is required for 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 of the deactivated first Scell, the maximum 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 according to the configured L3 MeasCycleScell, which can greatly reduce the deactivated SCell L3 measurement delay.

[0116] Optionally, a. the performance indicator of the L1 measurement is determined according to the SSB period of the measurement object, and the performance indicator of the L3 measurement is determined according to the SMTC period of the measurement object;

[0117] Alternatively, b. the performance index of the L1 measurement and the performance index of the L3 measurement are both determined according to the SSB period of the measurement object. The SSB periods of the serving cell and the neighboring cell requiring L1 measurement are always equal.

[0118] Optionally, if for a certain deactivated SCell frequency point, neither the configured L1 nor the configured L3 requires gap measurement, the measurement time and related performance indicators of L3 and L1 are determined according to the SSB.

[0119] In the prior art, the performance indicators 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 measurement delay to save power in the terminal.

[0121] Among them, T PSS / SSS_sync_intraIndicates the detection time of PSS / SSS (synchronization signal) of the same frequency in the synchronous state; Ceil is the ceil function; K p Indicates the scaling factor of the SSB frequency to be measured without the need for a measurement gap; CSSF intra Indicates the scaling factor of a specific carrier on the same frequency.

[0122] In the Scell ​​measurement method provided in the embodiment of the present application, the deactivated SCell L3 measurement can be performed based on the SSB (instead of measCycleSCell), thereby reducing the deactivated SCell L3 measurement delay. The relevant performance indicators can be replaced by the SSB of the measurement object instead of measCycleSCell, as shown in Table 2, where T SSB is the SSB period of the measurement object.

[0123] Table 2 Time period

[0124] Optionally, an embodiment of the present application provides a method for determining interruption caused by measurement when L1 / L3 measurement is configured for a deactivated SCell:

[0125] If both L1 and L3 measurements are configured for a deactivated SCell frequency, the performance indicator of the L1 measurement is determined based on the SSB period of the measurement object, and the performance indicator of the L3 measurement is determined based on the SMTC period of the measurement object; or if both the performance indicator of the L1 measurement and the performance indicator of the L3 measurement are determined based on the SSB period of the measurement object, the interruption of the L1 / L3 measurement is determined as follows:

[0126] The L1 measurement and the L3 measurement satisfy at least one of the following:

[0127] 1) The network does not configure a measurement period for the first Scell, and neither the L1 measurement nor the L3 measurement is interrupted.

[0128] For example, the system is not configured with measCycleSCell. In this case, L1 and L3 measurements are not interrupted, thereby improving system throughput.

[0129] 2) The network is configured with a measurement period for the first Scell, and neither the L1 measurement nor the L3 measurement generates interruption.

[0130] For example, if the system still configures measCycleSCell, the L3 measurement period is not based on measCycleSCell due to the use of methods a or b above. Therefore, even if measCycleSCell is greater than or equal to 640ms, L3 measurement will not be interrupted. In this case, L1 measurement will not be interrupted either, thus improving system throughput.

[0131] In other words, if both L1 and L3 are configured for a deactivated SCell frequency and gap measurements are not required, L3 and L1 measurements can be performed based on the SSB cycle, or L1 measurements can be performed using the SSB cycle and L3 measurements using the SMTC cycle. In this case, regardless of whether the system is configured with measCycleSCell, because the SSB or SMTC value will be less than 640ms, it is possible to ensure that L1 and L3 measurements of the deactivated SCell do not cause interruptions.
