Description

A method for determining measurement indicators, a communication node, a storage medium, and a program product. Technical Field

[0001] This application relates to the field of communication technology, and in particular to a method for determining measurement indicators, a communication node, a storage medium, and a program product. Background Technology

[0002] With operators increasingly focusing on base station energy consumption, base station energy saving has gradually become a priority in NR evolution. Based on current standard discussions, on-demand synchronization signal and physical broadcast channel block (on-demand SSB) is a candidate base station energy-saving technology that may be widely adopted in the future. On-demand SSB can be applied to secondary carriers in multi-carrier configurations and can be applied to various stages of the secondary carrier's lifecycle. When a terminal performs mobility measurements based on on-demand SSB, unlike ordinary SSB which can continuously receive signals once configured, on-demand SSB is dynamically or semi-statically activated and deactivated by the base station according to demand. Terminal measurement requires searcher resources. How to determine measurement indicators based on dynamically or semi-statically activated and deactivated on-demand SSB, so as to coordinate limited searcher resources holistically and better utilize them for all measurement objects, is a problem that needs to be solved.

[0019] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be arbitrarily combined with each other.

[0020] In New Radio (NR) systems, SSB signals serve as a broadcast signal and are widely used for time-frequency synchronization detection, channel quality detection, and mobility measurement. Traditionally, SSB signals are transmitted periodically by the base station on specific frequencies or in specific cells. To achieve energy savings for base stations, one approach is to break away from the traditional SSB transmission method, allowing the base station to dynamically or semi-statically activate and deactivate SSBs based on user needs, transmitting SSBs only periodically during activation periods, rather than through long-term periodic broadcasts. This flexibility in SSB transmission reduces unnecessary signal interference and resource waste, while also achieving energy savings on the base station side.

[0021] When applying on-demand SSB in multi-carrier scenarios, it is currently mainly used in secondary cells (SCells), and two application modes have been proposed: Mode 1 is the independent application of on-demand SSB, where only on-demand SSB transmission occurs on the target SCell, without traditional continuous synchronization signals and physical broadcast channel blocks (always-on SSB) transmission. Mode 2 involves joint transmission of on-demand SSB and traditional always-on SSB. To achieve energy saving on the base station side, the transmission period of traditional always-on SSB may be relatively long, thus relying on on-demand SSB to reduce latency for specific processes.

[0022] Limited by the terminal's baseband processing capabilities, regardless of whether the terminal performs Radio Resource Management (RRM) measurements based on Channel State Information Reference Signal (CSI-RS) or SSB, when the terminal needs to perform measurements on serving cells and neighboring cells at multiple frequency points, the number of frequency points or RSs that the terminal can simultaneously perform measurements must be determined based on the maximum number of searchers the terminal supports. Currently, the NR system assumes that the terminal supports a maximum of two searchers, and the NR protocol provides a specific method for allocating these two searchers among multiple Measurement Objects (MOs): Considering the criticality of measurements on the Primary Secondary Cell (PCell), the first searcher is independently allocated to SSB and CSI-RS measurements on the PCell. The second searcher is shared for measurements on all other frequency points, cells, and Radio Access Technologies (RATs) except the PCell. The way the Searcher allocates all the MOs to be measured will affect the calculation of the carrier-specific scaling factor (CSSF). The calculated CSSF, as a scaling factor, will ultimately affect the measurement period of each MO, that is, determine the measurement duration for a certain frequency point, cell or RAT.

[0023] Depending on the measurement type, CSSF is divided into two categories: CSSF_within gap, which performs measurements within the gap, and CSSF_outside gap, which performs measurements outside the gap. Furthermore, for each MO i to be measured, CSSF_... within gap,i And / or CSSF_outside gap,i. A larger CSSF value leads to longer cell detection and RRM measurement times for the terminal. Taking RRM measurement as an example, the impact of CSSF value on RRM measurement time can be seen as follows.

[0024] Table 1 shows the measurement period for intra-frequency measurements without gaps, including various methods for calculating the measurement period.

[0025] Table 1

[0026] Figure 1 is a flowchart of a measurement index determination method according to an embodiment. As shown in Figure 1, the measurement index determination method described in this embodiment is applied to a first communication node, and the method includes steps S110-S130:

[0027] S110, Receive configuration information for on-demand measurement signals.

[0028] Among them, the on-demand measurement signal can refer to the on-demand measurement signal; the configuration information can be information that configures the frequency, period, etc. of the on-demand measurement signal. For example, the frequency, carrier, cell, etc. of the on-demand measurement signal can be configured through the configuration information, and the period of the on-demand measurement signal can also be configured through the configuration signal, and so on.

[0029] The configuration information for on-demand measurement signals can be generated and sent by the second communication node. This configuration information can be generated based on information such as service type and requirements. The first communication node can receive the configuration information for on-demand measurement signals according to the agreed communication method.

[0030] S120. Receive activation information for the on-demand measurement signal and determine the activation state of the on-demand measurement signal based on the activation information.

[0031] Activation information can be understood as information related to activation operations, such as activating or deactivating on-demand measurement signals; activation information can be activation commands, deactivation commands, etc. The activation state can be activated or inactive, where inactive can be deactivated or not activated at all. On-demand measurement signals in an inactive state do not perform corresponding measurement operations.

[0032] After configuring the on-demand measurement signal, the first communication node can receive the activation information of the on-demand measurement signal and determine the activation status of the on-demand measurement signal based on the indication of the activation information. The configuration of the on-demand measurement signal only needs to be performed once. After the configuration is completed, the activation information of this on-demand measurement signal can be received at different times. That is, the activation information can be received multiple times according to actual business needs. For example, the activation information is received at time T1, and the activation status is determined to be active according to the indication of the activation information; the activation information is received at time T2, and the activation status is determined to be deactivated according to the indication of the activation information; the activation information is received again at time T3, and the activation status is determined to be active according to the indication of the activation information, thus realizing the switching of the activation status of the on-demand measurement signal.

[0033] S130. Determine the impact of the activation status on the measurement indicators based on the configuration information, and determine the measurement indicators based on the determination results.

[0034] The judgment result can be either "affects the measurement index," "does not affect the measurement index," or "affects the measurement index," "does not affect the measurement index," and so on. The measurement index can be parameters such as CSSF, measurement cycle, and measurement duration.

[0035] Based on the configuration information, determine the frequency, carrier, cell, and other information configured for the on-demand measurement information; determine whether the corresponding frequency, carrier, cell, etc., for the on-demand measurement information were originally configured with corresponding measurement signals, and determine the impact of the activation state on the measurement indicators based on whether measurement signals were configured; for example, if measurement signals were configured, determine the impact on the measurement indicators based on the type, frequency, activation state, etc. of the measurement signals, which may or may not affect the measurement indicators. Based on the determination result, determine whether the on-demand measurement signals affect the calculation of the measurement indicators. If they do not affect the calculation, the measurement indicators are directly determined; if they do affect the calculation, the on-demand measurement signals are considered, and the measurement indicators are calculated based on the on-demand measurement signals.

[0036] The measurement index determination method provided in this application embodiment receives configuration information of on-demand measurement signals; receives activation information of the on-demand measurement signals; determines the activation state of the on-demand measurement signals based on the activation information; judges the impact of the activation state on the measurement index based on the configuration information; and determines the measurement index based on the judgment result. This solves the problem of not being able to determine measurement indexes based on on-demand measurement signals. By receiving configuration information of on-demand measurement signals, determining how to configure the on-demand measurement signals, determining the activation state of the on-demand measurement signals based on the activation information, judging whether the activation state has an impact on the measurement index based on the configuration information, and finally determining the measurement index based on the judgment result, the method achieves the purpose of determining measurement indexes based on on-demand measurement signals, so as to coordinate limited searcher resources as a whole through measurement indexes.

[0037] In some embodiments, determining the impact of the activation status on the measurement metrics based on configuration information includes at least one of the following:

[0038] Based on the configuration information, determine the frequency corresponding to the on-demand measurement signal. If the frequency has a measurement signal of the same type as the on-demand measurement signal, determine that the activation state has no impact on the measurement index.

[0039] Based on the configuration information, determine the carrier or cell corresponding to the on-demand measurement signal. If the carrier or cell has a measurement signal of the same type as the on-demand measurement signal and is configured on a different frequency and meets the first condition, determine that the activation state has no impact on the measurement indicators.

[0040] Based on the configuration information, determine the carrier or cell corresponding to the on-demand measurement signal. If the carrier or cell has a measurement signal of the same type as the on-demand measurement signal but is configured on a different frequency and does not meet the first condition, determine the impact of the activation state on the measurement indicators.

[0041] Based on the configuration information, determine the frequency corresponding to the on-demand measurement signal. If the frequency does not have a measurement signal of the same type as the on-demand measurement signal, determine the impact of the activation state on the measurement indicators.

[0042] The first condition can be understood as a condition used to determine the impact of the activation state on the measurement index. The first condition can be set according to information such as the activation state, the time domain corresponding to the on-demand measurement signal, and the time domain corresponding to the measurement signal.

[0043] On-demand measurement signals can be configured on frequencies, carriers, or cells. The configuration information is analyzed to determine the corresponding frequency, carrier, or cell for the on-demand measurement signal. The frequency corresponding to the on-demand measurement signal is determined based on the configuration information. It is then determined whether this frequency has a measurement signal of the same type as the on-demand measurement signal. If so, the frequency has a measurement signal of the same type as the on-demand measurement signal, and the activation state does not affect the measurement indicators. If not, the frequency does not have a measurement signal of the same type as the on-demand measurement signal, and the activation state affects the measurement indicators. The carrier or cell corresponding to the on-demand measurement signal is determined based on the configuration information. If this carrier or cell has a measurement signal of the same type as the on-demand measurement signal but is configured on a different frequency, it is determined whether a first condition is met. If the first condition is met, the activation state does not affect the measurement indicators; if the first condition is not met, the activation state affects the measurement indicators.

[0044] In some embodiments, the frequency has a measurement signal of the same type as the on-demand measurement signal, including at least one of the following:

[0045] The frequency has a measurement signal, and the measurement signal is of the same type as the on-demand measurement signal;

[0046] The frequency has measurement target configuration information, and the measurement target configuration information contains a measurement signal of the same type as the on-demand measurement signal.

[0047] The measurement target configuration information, also known as the MO configuration information, can include multiple measurement signals of different types. If a frequency already has measurement target configuration information (meaning it already exists at that frequency), it is determined whether the measurement target configuration information contains a measurement signal of the same type as the on-demand measurement signal. If so, the frequency is considered to have a measurement signal of the same type as the on-demand measurement signal. Alternatively, if both conditions are met, the frequency is determined to have a measurement signal of the same type as the on-demand measurement signal.

[0048] In some embodiments, the carrier or cell has a measurement signal of the same type as the on-demand measurement signal and is configured at a different frequency, including at least one of the following:

[0049] The carrier or cell has a measurement signal of the same type as the on-demand measurement signal, and the measurement signal and the on-demand measurement signal are configured on different frequencies;

[0050] The carrier or cell has measurement target configuration information, which includes measurement signals of the same type as the on-demand measurement signals, but the measurement signals are configured on different frequencies than the on-demand measurement signals.

[0051] If a carrier or cell has a measurement signal, determine whether the measurement signal on the carrier or cell is of the same type as the on-demand measurement signal. If they are the same, determine the frequency configured for the measurement signal of the same type as the on-demand measurement signal. If the frequency of the measurement signal of the same type as the on-demand measurement signal is different from the frequency of the on-demand measurement signal, then the carrier or cell is considered to have a measurement signal of the same type as the on-demand measurement signal but configured on a different frequency. If a carrier or cell has measurement target configuration information, i.e., measurement target configuration information originally existed on that carrier or cell, determine whether the measurement target configuration information contains a measurement signal of the same type as the on-demand measurement signal. If it does, determine the frequency configured for the measurement signal of the same type as the on-demand measurement signal. If the frequency of the measurement signal of the same type as the on-demand measurement signal is different from the frequency of the on-demand measurement signal, then the carrier or cell is considered to have a measurement signal of the same type as the on-demand measurement signal but configured on a different frequency.

[0052] In some embodiments, the first condition includes at least one of the following:

[0053] The activation state is active and the time domain overlaps between the on-demand measurement signal and the measurement signal.

[0054] The activation state is active and the on-demand measurement signal and the measurement signal do not overlap in the time domain;

[0055] The on-demand measurement signals and the overall measurement signals are counted together.

[0056] Among them, counting the on-demand measurement signal and the measurement signal as a whole can be done by counting the on-demand measurement signal and the measurement signal as a whole as 1.

[0057] In some embodiments, the method further includes at least one of the following:

[0058] On-demand measurement signals have higher priority than measurement signals, and on-demand measurement signals are received at overlapping times.

[0059] Select the signal to be received from the on-demand measurement signal and the measurement signal, and receive the signal to be received when they overlap.

[0060] In this context, the signal to be received can be understood as the signal that needs to be received. When the activation state is active and the on-demand measurement signal and the measurement signal overlap in the time domain, since only one signal can be received at a time, one signal can be selected from the on-demand measurement signal and the measurement signal for reception. The signal can be selected based on priority: if the priority of the on-demand measurement signal is higher than that of the measurement signal, the on-demand measurement signal is received during the overlapping time; if the priority of the on-demand measurement signal is not higher than that of the measurement signal, the measurement signal is received during the overlapping time. Alternatively, a signal can be manually selected from the on-demand measurement signal and the measurement signal as the signal to be received, and received during the overlapping time. For example, a signal can be randomly selected from the on-demand measurement signal and the measurement signal, or a signal can be selected according to certain rules or indication information, etc.

[0061] In some embodiments, the on-demand measurement signal includes at least one of the following:

[0062] Synchronization signals and physical broadcast channel blocks;

[0063] Master synchronization signal;

[0064] Auxiliary synchronization signal;

[0065] Channel state information reference signal;

[0066] Track the reference signal;

[0067] Data and demodulation reference signal.

[0068] In some embodiments, the measurement signal includes at least one of the following:

[0069] Synchronization signals and physical broadcast channel blocks;

[0070] Master synchronization signal;

[0071] Auxiliary synchronization signal;

[0072] Channel state information reference signal;

[0073] Track the reference signal;

[0074] Data and demodulation reference signal.

[0075] Both on-demand measurement signals and measurement signals can include at least one of the following: synchronization signals and physical broadcast channel blocks (SSBs), primary synchronization signals (PSS), secondary synchronization signals (SSS), channel state information reference signals (CSI-RS), tracking reference signals (TRS), and demodulation reference signals (DMRS).

[0076] In some embodiments, the measurement index is determined based on the judgment result, including at least one of the following:

[0077] When the activation state affects the measurement index and the activation state is active, the frequency configured corresponding to the on-demand measurement signal is used as the frequency to be measured, the on-demand measurement signal is used as the signal to be measured, and the measurement index is determined according to the first rule.

[0078] When the activation state affects the measurement index, or when the activation state is inactive and there is no signal to be measured at the frequency configured for the on-demand measurement signal, the measurement index is determined according to the second rule.

[0079] In this context, both the first and second rules can be understood as methods for determining measurement indicators, and both rules can be predetermined. The frequency to be measured can be understood as the frequency at which the measurement needs to be performed, i.e., at which frequency the measurement will be performed; the signal to be measured can be understood as the signal at which the measurement will be performed.

[0080] The determination is based on the judgment result to determine whether the activation state affects the measurement index. If the activation state affects the measurement index, it is determined whether the activation state is active or inactive. If the activation state affects the measurement index and the activation state is active, the frequency configured corresponding to the on-demand measurement signal is taken as the frequency to be measured, and the on-demand measurement signal is taken as the signal to be measured. When determining the measurement index, the first rule is used to determine the measurement index based on the frequency to be measured and the signal to be measured. For example, when calculating the measurement index, there are other signals besides the on-demand measurement signal, i.e., besides the frequency to be measured and the signal to be measured, there are other frequencies and signals to be measured. The measurement index is calculated based on all the signals and frequencies to be measured, according to the method for determining measurement indexes in related technologies. If the activation state affects the measurement index, it is determined whether the activation state is active or inactive. If the activation state is inactive and the frequency configured corresponding to the on-demand measurement signal does not have a signal to be measured, then it can be considered that one signal to be measured has been reduced, and the measurement index can be determined according to the second rule. The measurement index can be a parameter such as measurement period, measurement duration, CSSF, etc., and the calculation method may differ for different parameter values.

[0081] In some embodiments, the measurement index is determined according to a first rule, including at least one of the following:

[0082] Measurement parameters are determined based on a rule that adds 1 to the carrier-specific scaling factor.

[0083] Measurement parameters are determined based on the rule that the carrier-specific scaling factor is equal to 1.

[0084] In determining the measurement indicators, a carrier-specific scaling factor is added by 1 or set to 1, and the measurement indicators are calculated accordingly. For example, the CSSF is added by 1, and information such as the measurement period, measurement duration, detection duration, and synchronization signal index acquisition duration are calculated based on the obtained CSSF. One or more of these information, such as the measurement period, measurement duration, detection duration, and synchronization signal index acquisition duration, are used as measurement indicators. The measurement duration can be calculated based on the CSSF and corresponding tables, for example, according to Table 1 in the embodiments of this application. The determined measurement indicators can be measurement indicators for on-demand measurement signals or measurement indicators for other measurement signals.

[0085] In some embodiments, the measurement metrics are determined based on a rule that a carrier-specific scaling factor equals 1, including:

[0086] During the fast measurement window while the on-demand measurement signal remains active, the measurement parameters of the on-demand measurement signal are determined based on the rule that the carrier-specific scaling factor equals 1.

[0087] During the fast measurement window when the on-demand measurement signal is held active, the on-demand measurement signal can be considered to have the highest priority and is measured first. Therefore, the measurement index of the on-demand measurement signal is determined based on the rule that the carrier-specific scaling factor is equal to 1.

[0088] For example, during the calculation of measurement metrics, if the activation state affects the measurement metrics and the activation state is active, the CSSF of both the on-demand measurement signal and other measurement signals is incremented by 1. Based on this, the measurement metrics of the on-demand measurement signal and other measurement signals are calculated separately. If the activation state affects the measurement metrics and the activation state is active, during the fast measurement window when the on-demand measurement signal remains active, the CSSF of the on-demand measurement signal is equal to 1, and the CSSF of other measurement signals is incremented by 1. Based on this, the measurement metrics of the on-demand measurement signal and other measurement signals are calculated separately. Here, the other measurement signals can be measurement signals configured in other MOs.

[0089] In some embodiments, determining the measurement index according to the second rule includes:

[0090] The measurement parameters are determined based on the rule of reducing the carrier-specific scaling factor by 1.

[0091] In determining the measurement indicators, the carrier-specific scaling factor is reduced by 1, and the measurement indicators are calculated based on this. For example, the CSSF is reduced by 1, and information such as the measurement period, measurement duration, detection duration, and synchronization signal index acquisition duration are calculated based on the obtained CSSF. One or more of the information such as the measurement period, measurement duration, detection duration, and synchronization signal index acquisition duration are used as measurement indicators. The measurement duration can be calculated based on the CSSF and the corresponding table. For example, the measurement duration is calculated according to Table 1 in the embodiments of this application.

[0092] In some embodiments, the method further includes:

[0093] When neighbor cell measurements are required at the frequency of the on-demand measurement signal, determine the measurement type of the neighbor cell measurement.

[0094] To determine whether neighbor cell measurement is necessary at the frequency of the on-demand measurement signal, for example, the serving cell corresponding to the on-demand measurement signal or the measurement signal at the serving cell's frequency can be used. If it is determined that neighbor cell measurement is necessary at the frequency of the on-demand measurement signal, the measurement type of the neighbor cell measurement is determined based on the activation status of the on-demand measurement signal, the measurement signal at the serving cell, and other information. The measurement type can be same-frequency measurement, different-frequency measurement, etc.

[0095] In some embodiments, the method further includes at least one of the following:

[0096] Based on the configuration information, determine the serving cell or the frequency corresponding to the serving cell that corresponds to the on-demand measurement signal. If there is no measurement signal of the same type as the on-demand measurement signal on the serving cell or the frequency corresponding to the serving cell, and the measurement target is configured on the frequency of the on-demand measurement signal, determine to perform neighbor cell measurement.

[0097] Based on the configuration information, determine the serving cell or the frequency corresponding to the serving cell for the on-demand measurement signal. If there is a measurement signal configuration of the same type as the on-demand measurement signal on the serving cell or the frequency corresponding to the serving cell, but the frequency of the configured measurement signal is different from the frequency of the on-demand measurement signal, determine to perform neighbor cell measurement.

[0098] Analyze the configuration information to determine the serving cell or frequency corresponding to the on-demand measurement signal. If the serving cell or frequency does not have a measurement signal of the same type as the on-demand measurement signal (i.e., the serving cell or frequency configured with the on-demand measurement signal did not originally have a measurement signal of the same type as the on-demand measurement signal), and if a measurement target is configured on the frequency of the on-demand measurement signal, then neighbor cell measurement is determined to be performed; if the serving cell or frequency originally had a measurement signal of the same type as the on-demand measurement signal, and the frequency of the configured measurement signal is different from the frequency of the on-demand measurement signal, then neighbor cell measurement is determined to be performed. Alternatively, if multiple conditions above are met, then neighbor cell measurement is determined to be performed.

[0099] In some embodiments, determining the measurement type of neighboring cell measurements includes at least one of the following:

[0100] The measurement type of the neighboring cell measurement was determined to be a same-frequency measurement;

[0101] When the activation state is active, the measurement type of the neighboring cell measurement is determined to be a same-frequency measurement;

[0102] If the activation status is inactive, the measurement type of the neighboring cell measurement is determined to be inter-frequency measurement;

[0103] If the frequency of the neighboring cell measurement is the same as the frequency of the measurement signal on the serving cell corresponding to the on-demand measurement signal, the measurement type is determined to be co-frequency measurement.

[0104] When the frequency of the neighboring cell measurement differs from the frequency of the measurement signal on the serving cell corresponding to the on-demand measurement signal, the measurement type is determined to be inter-frequency measurement.

[0105] If the frequency of the neighboring cell measurement is different from the frequency of the measurement signal on the serving cell corresponding to the on-demand measurement signal and the activation status is inactive, the measurement type is determined to be inter-frequency measurement.

[0106] If the frequency of the neighboring cell measurement is different from the frequency of the measurement signal on the serving cell corresponding to the on-demand measurement signal and the activation status is active, the measurement type is determined to be co-frequency measurement.

[0107] When determining the measurement type of a neighboring cell measurement, it can be determined based on the activation state or not. For example, regardless of whether the on-demand measurement signal is activated, as long as the on-demand measurement signal is configured on that frequency, the measurement type of the neighboring cell measurement is intra-frequency measurement. Alternatively, the measurement type can be determined based on the activation state: when the activation state is active (i.e., during the period when the on-demand measurement signal is activated on the frequency), the measurement type of the neighboring cell measurement is intra-frequency measurement; when the activation state is inactive (i.e., during the period when the measurement signal is deactivated or has not yet been activated), the measurement type of the neighboring cell measurement is inter-frequency measurement. Alternatively, the measurement type can be determined based on the frequency: when the frequency of the neighboring cell measurement is the same as the frequency of the measurement signal on the serving cell, the measurement type is determined to be intra-frequency measurement; when the frequency of the neighboring cell measurement is different from the frequency of the measurement signal on the serving cell, the measurement type is determined to be intra-frequency measurement. Or, the measurement type can be determined based on both the frequency and the activation state: when the frequency of the neighboring cell measurement is different from the frequency of the measurement signal on the serving cell and the activation state is inactive, the measurement type is determined to be inter-frequency measurement; when the frequency of the neighboring cell measurement is different from the frequency of the measurement signal on the serving cell and the activation state is active, the measurement type is determined to be intra-frequency measurement. Among them, the serving cell refers to the serving cell configured corresponding to the on-demand measurement signal, that is, the serving cell configured with the on-demand measurement signal.

[0108] In some embodiments, the method further includes:

[0109] If the second condition is met, determine whether neighboring cell measurements at the frequency of the on-demand measurement signal are performed within the gap.

[0110] The second condition can be understood as a condition used to trigger the determination of whether the neighbor cell measurement is performed within the gap; the second condition can be set according to the type, frequency, serving cell, and frequency range of the on-demand measurement signal.

[0111] A second condition is predetermined. If the second condition is met, it is further determined whether the neighboring cell measurement at the frequency of the on-demand measurement signal is performed within the gap.

[0112] In some embodiments, the second condition includes at least one of the following:

[0113] According to the configuration information, the on-demand measurement signal corresponds to a service cell or the frequency range of the service cell does not have a measurement signal of the same type as the on-demand measurement signal.

[0114] The on-demand measurement signal is determined based on the configuration information and corresponds to the serving cell or the serving cell has a measurement signal of the same type as the on-demand measurement signal but configured at a different frequency.

[0115] In some embodiments, determining whether a neighboring cell measurement at the frequency of the on-demand measurement signal is performed within the gap includes at least one of the following:

[0116] If the frequency of the on-demand measurement signal completely includes the frequency of the measurement signal in the neighboring cell, it is determined that the neighboring cell measurement is not performed within the gap;

[0117] If the frequency of the on-demand measurement signal does not fully encompass the frequency of the measurement signal in the neighboring cell, it is determined that the neighboring cell measurement will be performed within the gap.

[0118] If the frequency of the on-demand measurement signal completely includes the frequency of the measurement signal of the neighboring cell and the activation state is active, it is determined that the neighboring cell measurement is not performed within the gap;

[0119] If the frequency of the on-demand measurement signal completely includes the frequency of the measurement signal of the neighboring cell measurement and the activation state is inactive, it is determined that the neighboring cell measurement is performed within the gap.

[0120] If the frequency of the on-demand measurement signal does not completely encompass the frequency of the measurement signal in the neighboring cell and the activation state is active, it is determined that the neighboring cell measurement is performed within the gap.

[0121] If the activation state is inactive, it is determined that neighbor cell measurements are performed within the gap.

[0122] The phrase "not fully included" refers to either including or excluding the frequencies of neighboring cell measurement signals. Specifically, it means that the frequency of the on-demand measurement signal may or may not include the frequencies of neighboring cell measurement signals. Whether a neighboring cell measurement is performed within a gap can be determined based on the activation state, the frequency of the on-demand measurement signal, and the frequency of the measurement signal. Neighbor cell measurement can be related to the frequency of the on-demand measurement signal and the frequency at which the measurement signal is located, but is independent of the activation state. For example, if the frequency of the on-demand measurement signal completely includes the frequency at which the neighbor cell measurement signal is located, it is determined that the neighbor cell measurement will not be performed within the gap; if the frequency of the on-demand measurement signal does not completely include the frequency at which the neighbor cell measurement signal is located, it is determined that the neighbor cell measurement will be performed within the gap. Alternatively, neighbor cell measurement can be related to the frequency of the on-demand measurement signal, the frequency at which the measurement signal is located, and the activation state. If the frequency of the on-demand measurement signal completely includes the frequency at which the neighbor cell measurement signal is located, and the activation state of the on-demand measurement signal is active, it is determined that the neighbor cell measurement will not be performed within the gap; if the activation state of the on-demand measurement signal is inactive, it is determined that the neighbor cell measurement will be performed within the gap. Alternatively, if the activation state is inactive, it is determined that the neighbor cell measurement will be performed within the gap.

[0123] In some embodiments, the method further includes:

[0124] If the measurement type of the neighboring cell measurement for the frequency of the on-demand measurement signal is same-frequency measurement and the third condition is met, then the neighboring cell measurement is performed.

[0125] The third condition is: there are no neighboring cells with the frequencies of the main cell or main auxiliary cell to be measured within the same frequency band.

[0126] The third condition is used to determine whether to perform neighbor cell measurements. On-demand measurement signals may affect neighbor cell measurements, for example, whether to perform them. The third condition is that there are no neighbor cell measurements of the primary or secondary cell frequencies to be measured within the same frequency band. If the measurement type of the neighbor cell measurement at the frequency of the on-demand measurement signal is a co-frequency measurement, the decision to perform the neighbor cell measurement is based on the third condition. If the third condition is met, i.e., there are no neighbor cell measurements of the primary or secondary cell to be measured within the same frequency band, then the neighbor cell measurement is determined to be necessary. For neighbor cell measurements at the frequency of the on-demand measurement signal that are of inter-frequency measurement, this neighbor cell measurement is ultimately required, and no decision on whether to perform it is unnecessary.

[0127] When neighboring cell measurements exist within the same frequency band at the frequency of the primary or secondary cell to be measured, the neighboring cell measurements at the frequency of the primary or secondary cell to be measured can be considered to have higher priority than the neighboring cell measurements, and the neighboring cell measurements at the frequency of the primary or secondary cell to be measured should be performed first.

[0128] In some embodiments, the frequency band is a frequency range.

[0129] In some embodiments, the method further includes:

[0130] During the activation of the on-demand measurement signal, a fast measurement is performed within the fast measurement window based on the on-demand measurement signal cycle configuration. After the fast measurement window, measurements are performed based on the periodic secondary cell measurement cycle.

[0131] The fast measurement window can be understood as a time window, i.e., a period of time. The fast measurement window can be pre-configured, for example, by its size, start time, end time, etc. During the activation of the on-demand measurement signal, fast measurements are performed within a fast measurement window based on the on-demand measurement signal cycle configuration. After the fast measurement window, measurements are performed based on the periodic secondary cell measurement cycle. For example, the size and start time of the fast measurement window are determined, and the position of the fast measurement window is determined based on the start time and the size of the fast measurement window. Fast measurements are performed within the fast measurement window based on the on-demand measurement signal cycle configuration. After the fast measurement window, measurements are performed based on the periodic secondary cell measurement cycle. The size and start time of the fast measurement window can be determined based on configuration information, or based on indication information, preset rules, etc.

[0132] In some embodiments, on-demand measurement signals are preferentially measured within a fast measurement window.

[0133] Within the fast measurement window, the on-demand measurement signal has a higher priority than other measurement signals and is therefore executed first. That is, the first communication node prioritizes the on-demand measurement signal for measurement within the fast measurement window.

[0134] In some embodiments, the size of the rapid measurement window is determined according to at least one of the following:

[0135] The first time refers to the time when the first communication node completes cell detection and cell deactivation measurement for the first cell;

[0136] The second time is the time when the first communication node completes the deactivation cell measurement under the condition that the fourth condition is met;

[0137] The third time is the time when the first communication node completes the deactivation cell measurement and reports the deactivation cell measurement report.

[0138] The minimum values ​​at the first and third times;

[0139] The minimum values ​​of the second and third times;

[0140] Configuration information for the quick measurement window.

[0141] The fast measurement window can be determined based on any of the above methods, such as based on a first time, a second time, a third time, the minimum value between the first and third times, the configuration information of the fast measurement window, or a combination of the above methods, etc. The first time is the time it takes for the first communication node to complete cell detection and measurement of the deactivated cell; that is, the first time equals the time it takes for the first communication node to complete cell detection plus the time it takes to measure the deactivated cell. The second time is the time it takes for the first communication node to complete the deactivated cell measurement when the fourth condition is met. The third time is the time it takes for the first communication node to complete the deactivated cell measurement and report the deactivated cell measurement report.

[0142] In some embodiments, the starting point of the rapid measurement window is determined according to at least one of the following:

[0143] The moment when the first communication node receives the activation information of the on-demand measurement signal;

[0144] The moment when the first communication node receives the activation information of the on-demand measurement signal for the first time;

[0145] The moment when the first communication node receives the activation information of the on-demand measurement signal and completes the processing;

[0146] The moment when the first communication node receives the activation information of the on-demand measurement signal and completes the processing for the first time.

[0147] For example, the starting point of the fast measurement window can be the moment when the first communication node receives the activation information of the on-demand measurement signal, or the N1 time units after the moment when the first communication node receives the activation information of the on-demand measurement signal; or the starting point of the fast measurement window can be the moment when the first communication node receives the on-demand measurement signal for the first time after receiving the activation information of the on-demand measurement signal; or the starting point of the fast measurement window can be the N2 time units after the moment when the first communication node receives the activation information of the on-demand measurement signal for the first time; or the starting point of the fast measurement window can be the moment when the first communication node receives the activation information of the on-demand measurement signal and completes the processing, or the starting point of the fast measurement window can be the N3 time units after this moment; or the starting point of the fast measurement window can be the moment when the first communication node receives the activation information of the on-demand measurement signal and completes the processing, or the starting point of the fast measurement window can be the N4 time units after this moment, and so on. The time unit can be a time unit such as millisecond, microsecond, nanosecond, or a time unit such as a wireless frame, subframe, time slot, or OFDM symbol. The values ​​of N1, N2, N3, and N4 can be the same or different.

[0148] In some embodiments, the fourth condition includes at least one of the following:

[0149] Within the set time frame, the first communication node performs cell detection on the deactivated cell;

[0150] Within the frequency band where the deactivated cell is located, there exists another active primary cell;

[0151] Within the frequency band where the deactivated cell is located, there exists another active primary and secondary cell;

[0152] Within the frequency band where the deactivated cell is located, there exists another auxiliary cell that is in an active state;

[0153] Within the frequency band of the deactivated cell, there exists another active main cell, and the frequency range of the main cell and the frequency range of the deactivated cell are continuous in the frequency domain.

[0154] Within the frequency band of the deactivated cell, there exists another active primary and secondary cell, and the frequency ranges of the primary and secondary cell and the deactivated cell are continuous in the frequency domain.

[0155] Within the frequency band of the deactivated cell, there exists another active auxiliary cell, and the frequency range of the auxiliary cell and the frequency range of the deactivated cell are continuous in the frequency domain.

[0156] In some embodiments, the set time range is determined based on at least one of the following:

[0157] Predefined;

[0158] Configure according to the third configuration information.

[0159] In some embodiments, the third configuration information is semi-static configuration information.

[0160] In some embodiments, the time required to complete cell detection for deactivating a cell includes at least the time required for the first communication node to perform N measurements based on the on-demand measurement signal.

[0161] In some embodiments, N is determined according to at least one of the following:

[0162] Predefined;

[0163] Configure according to the first configuration information.

[0164] In some embodiments, the first configuration information is semi-static configuration information.

[0165] The size of N can be predefined or configured based on the first configuration information. For example, the first communication node receives the first configuration information and configures the size of N based on the first configuration information. Alternatively, it can be determined based on both the predefined value and the first configuration information. For example, multiple values ​​of N can be predefined and numbered, and the value of N can be determined based on the number of the value indicated by the first configuration information.

[0166] In some embodiments, the time required to complete the deactivation cell measurement includes at least the time required for the first communication node to perform M measurements based on the on-demand measurement signal;

[0167] In some embodiments, M is determined according to at least one of the following:

[0168] Predefined;

[0169] Configure according to the second configuration information.

[0170] In some embodiments, the second configuration information is semi-static configuration information.

[0171] The size of M can be predefined or configured based on the second configuration information. For example, the first communication node receives the second configuration information and configures the size of M based on the second configuration information. Alternatively, it can be determined based on both the predefined and the second configuration information. For example, multiple values ​​of M are predefined and numbered, and the value of M is determined based on the number of the value indicated by the second configuration information.

[0172] In some embodiments, the activation information includes at least one of the following:

[0173] Activation command;

[0174] Deactivate command;

[0175] Activation time.

[0176] An activation command can be used to instruct the on-demand measurement signal to be activated, and a deactivation command can be used to instruct the on-demand measurement signal to be deactivated. The activation and deactivation of the on-demand measurement signal can also be controlled by the activation command and the activation time. For example, the activation information includes an activation command and an activation time t. After receiving the activation information, the first communication node activates the on-demand measurement signal based on the activation command. The activation state of the on-demand measurement signal is activated. After a duration of t, it is automatically deactivated, and the activation state is updated to inactive.

[0177] In some embodiments, the activation time includes at least one of the following:

[0178] The duration of the active state;

[0179] The number of times a signal is sent during activation is measured on demand.

[0180] In some embodiments, the measurement metrics include at least one of the following:

[0181] Same frequency measurement duration;

[0182] Inter-frequency measurement duration;

[0183] Community testing duration;

[0184] Synchronization signal detection duration;

[0185] Synchronization signal index acquisition duration;

[0186] Acquisition time of inter-frequency synchronization signal index.

[0187] The measurement index determination method provided in this application receives activation information of on-demand measurement signals, determines the activation state of the on-demand measurement signals based on the activation information (activation state can be active or inactive), judges the impact of the activation state on the measurement index based on configuration information (activation state can affect the measurement index or not), and determines the measurement index based on the judgment result, thus solving the problem of not being able to determine measurement indexes based on on-demand measurement signals. In the process of determining measurement indexes, the impact of on-demand measurement signals is considered, achieving the purpose of determining measurement indexes based on on-demand measurement signals, so as to coordinate limited searcher resources as a whole through measurement indexes. The method also considers the impact of on-demand measurement signals to determine whether to perform neighbor cell measurements, the measurement type of neighbor cell measurements, and whether neighbor cell measurements are performed within the interval. The method provided in this application can analyze the impact of on-demand measurement signals on measurement indexes, neighbor cell measurements, etc., after configuring on-demand measurement signals, perform resource coordination, rationally plan resources, and improve resource utilization efficiency.

[0188] Figure 2 is a flowchart of another method for determining measurement indicators according to an embodiment. As shown in Figure 2, the method for determining measurement indicators according to this embodiment is applied to a second communication node, and the method includes steps S210-S220:

[0189] S210. Send configuration information for on-demand measurement signals.

[0190] The second communication node can generate configuration information for on-demand measurement signals and send it to the first communication node. This configuration information can be generated based on service type, requirements, or other information, or according to certain rules. The second communication node can send the configuration information for on-demand measurement signals according to agreed-upon communication methods.

[0191] S220. Send activation information for on-demand measurement signal so that the first communication node determines the activation state of on-demand measurement signal based on activation information, judges the impact of activation state on measurement index based on configuration information, and determines measurement index based on judgment result.

[0192] The second communication node generates and sends activation information for the on-demand measurement signal. This activation information can be generated according to certain rules or methods. The second communication node indicates the activation status of the on-demand measurement signal through this activation information. The configuration of the on-demand measurement signal can be performed only once. After configuration, the activation information can be sent at different times, meaning it can be sent multiple times based on actual business needs. For example, activation information can be sent at time T1, indicating the on-demand measurement signal is active; at time T2, activation information can be sent, indicating the on-demand measurement signal is deactivated; and at time T3, activation information can be sent again. The activation status of the on-demand measurement signal is switched based on the activation information. The first communication node determines the activation status of the on-demand measurement signal based on the activation information, judges the impact of the activation status on the measurement indicators based on the configuration information, and determines the measurement indicators based on the judgment result.

[0193] The measurement index determination method provided in this application embodiment sends configuration information for on-demand measurement signals and activation information for on-demand measurement signals, so that the first communication node determines the activation state of the on-demand measurement signals based on the activation information, judges the impact of the activation state on the measurement index based on the configuration information, and determines the measurement index based on the judgment result. This solves the problem of not being able to determine measurement indexes based on on-demand measurement signals. By sending configuration information for on-demand measurement signals, the method instructs how to configure the on-demand measurement signals, and sends activation information for on-demand measurement signals, the method indicates the activation state of the on-demand measurement signals. The first communication node judges whether the activation state affects the measurement index based on the configuration information, and finally determines the measurement index based on the judgment result. This achieves the purpose of determining measurement indexes based on on-demand measurement signals, so as to coordinate limited searcher resources as a whole through measurement indexes.

[0194] In some embodiments, the activation information includes at least one of the following:

[0195] Activation command;

[0196] Deactivate command;

[0197] Activation time.

[0198] In some embodiments, the activation time includes at least one of the following:

[0199] The duration of the active state;

[0200] The number of times a signal is sent during activation is measured on demand.

[0201] In some embodiments, the on-demand measurement signal includes at least one of the following:

[0202] Synchronization signals and physical broadcast channel blocks;

[0203] Master synchronization signal;

[0204] Auxiliary synchronization signal;

[0205] Channel state information reference signal;

[0206] Track the reference signal;

[0207] Demodulation reference signal.

[0208] In some embodiments, the method further includes:

[0209] Send at least one of the following messages:

[0210] Configuration information for the quick measurement window;

[0211] First configuration information;

[0212] Second configuration information;

[0213] Third configuration information.

[0214] In some embodiments, the measurement metrics include at least one of the following:

[0215] Same frequency measurement duration;

[0216] Inter-frequency measurement duration;

[0217] Community testing duration;

[0218] Synchronization signal detection duration;

[0219] Synchronization signal index acquisition duration;

[0220] Acquisition time of inter-frequency synchronization signal index.

[0221] The process of determining measurement indicators is illustrated through the following examples:

[0222] Taking the first communication node as the terminal and the second communication node as the base station as an example, the following operations that the terminal can perform can all be performed by the first communication node, and the operations that the base station can perform can all be performed by the second communication node.

[0223] Example 1:

[0224] The base station can activate or deactivate the on-demand measurement signal on a specific serving cell or frequency point via RRC signaling, MAC CE, or DCI. With the activation and deactivation of the on-demand measurement signal, the number of serving cells, frequencies, or MOs to be measured by the User Equipment (UE) will change, and the corresponding CSSF calculation will be updated. The terminal should use the updated CSSF calculation to determine the corresponding scaling factor value, thereby determining the measurement duration of the serving cell, frequency point, and MO to be measured. At least one of the following methods can be used to determine the CSSF:

[0225] 1) If the frequency at which the on-demand measurement signal is activated or deactivated already has a measurement RS or MO configuration, and the measurement RS and the on-demand measurement signal are of the same type, or the MO configuration includes an RS of the same type as the on-demand measurement signal, then the activation or deactivation of the on-demand measurement signal will not affect the CSSF determination. Specifically, the CSSF can be either CSSF_within gap or CSSF_outside gap.

[0226] 2) If the carrier or cell where the activation or deactivation of the on-demand measurement signal occurs already has a measurement RS or MO configuration, and the measurement RS and the on-demand measurement signal are of the same type, or the MO configuration includes an RS of the same type as the on-demand measurement signal, and the measurement RS and the on-demand measurement signal are configured on different frequencies, or the RS and on-demand measurement signals included in the MO configuration are configured on different frequencies, then the activation or deactivation of the on-demand measurement signal will not affect the CSSF determination. Specifically, the CSSF can be CSSF_within gap or CSSF_outside gap.

[0227] 2.1) When an on-demand measurement signal is activated, during the period the on-demand measurement signal remains active, if the on-demand measurement signal overlaps with the RS in the measurement RS or MO configuration in the time domain, then in the overlapping occasion, the priority of the on-demand measurement signal is higher than that of the RS in the measurement RS or MO configuration, and the UE can choose to receive only the on-demand measurement signal in the overlapping occasion. Alternatively,

[0228] 2.2) The base station ensures that the activated on-demand measurement signal does not overlap with the RS in the measurement RS or MO configuration in the time domain. When calculating the CSSF, the on-demand measurement signal and the RS in the measurement RS or MO configuration are counted as a whole as 1. Alternatively,

[0229] 2.3) When an on-demand measurement signal is activated, if the on-demand measurement signal overlaps with the RS in the measurement RS or MO configuration in the time domain during the period the on-demand measurement signal remains active, then the UE will choose to receive only one of the signals during the overlap.

[0230] 2.4) When an on-demand measurement signal is activated, within the fast measurement window during the on-demand measurement signal's active period, if the on-demand measurement signal overlaps in the time domain with other RSs configured by the MO, then in the overlapping occasion, the on-demand measurement signal has the highest priority, and the UE only receives the on-demand measurement signal. Outside the fast measurement window during the on-demand measurement signal's active period, the UE falls back to receiving on-demand measurement signals using the secondary cell measurement cycle (measCycleSCell). If the on-demand measurement signal overlaps in the time domain with other RSs configured by the MO, then in the overlapping occasion, the UE automatically selects to receive only one of the signals.

[0231] 3) If the carrier or cell where the activation or deactivation of the on-demand measurement signal occurs already has a measurement RS or MO configuration, and the measurement RS and the on-demand measurement signal are of the same type, or the MO configuration includes an RS of the same type as the on-demand measurement signal, and the measurement RS and the on-demand measurement signal are configured on different frequencies, or the RS and on-demand measurement signals included in the MO configuration are configured on different frequencies, then the activation or deactivation of the on-demand measurement signal will affect the CSSF determination. Specifically, the CSSF can be CSSF_within gap or CSSF_outside gap. Specifically:

[0232] 3.1) When an on-demand measurement signal is activated, the frequency is treated as a new frequency to be measured, and the on-demand measurement signal is treated as a new signal to be measured; the CSSF calculation increments by 1. Alternatively,

[0233] 3.2) When an on-demand measurement signal is deactivated, if there is no longer a measurement signal at the frequency of the on-demand measurement signal, the CSSF calculation should be reduced by 1.

[0234] 4) If the activation or deactivation of the on-demand measurement signal did not originally involve a measured RS or MO configuration at that frequency, and the measured RS and the on-demand measurement signal are of the same type, and the MO configuration includes an RS of the same type as the on-demand measurement signal, then the activation or deactivation of the on-demand measurement signal will affect the CSSF determination. Specifically, the CSSF can be either CSSF_within gap or CSSF_outside gap. Specifically:

[0235] 4.1) When an on-demand measurement signal is activated, the frequency is treated as a new frequency to be measured, and the on-demand measurement signal is treated as a new signal to be measured; the CSSF calculation increments by 1. Alternatively,

[0236] 4.2) When an on-demand measurement signal is deactivated, if there is no longer a measurement signal at that frequency, the CSSF calculation should be decremented by 1.

[0237] 4.3) When an on-demand measurement signal is activated, during the fast measurement window while the on-demand measurement signal remains active, it is treated as a newly added measurement signal. The UE prioritizes measuring this on-demand measurement signal, while measurement signals configured by other MOs have lower priority. Therefore, for the determination of the measurement index of this on-demand measurement signal, the CSSF value is set to 1. For the determination of the measurement index of measurement signals configured by other MOs, the CSSF calculation is incremented by 1.

[0238] 4.4) Once an on-demand measurement signal is activated, outside the fast measurement window during the period when the on-demand measurement signal remains active, the terminal measures the on-demand measurement signal based on the measurement cycle measCycleSCell. For the determination of the measurement parameters of this on-demand measurement signal, the CSSF calculation, based on the cycle measCycleSCell, takes into account this on-demand measurement signal and measurement signals from other MO configurations.

[0239] The RS type mentioned above can be any type of RS used to perform measurements, such as CSI-RS, SSB, or Sounding Reference Signal (SRS).

[0240] In some embodiments, CSSF is used to determine measurement metrics.

[0241] In some embodiments, the measurement metrics include at least one of the following:

[0242] Same frequency measurement duration;

[0243] Inter-frequency measurement duration;

[0244] Community testing duration;

[0245] Synchronization signal detection duration;

[0246] Synchronization signal index acquisition duration;

[0247] Acquisition time of inter-frequency synchronization signal index.

[0248] Example 2:

[0249] A terminal performs mobility management measurements on a specific frequency. Based on the relationship between this frequency, the serving cell frequency, and the numberology, it determines whether a measurement based on a certain RS (Radio Recognition) on that frequency is a co-frequency or inter-frequency measurement. The specific cell detection and RRM (Radio Recognition Management) measurement metrics differ for co-frequency and inter-frequency measurements. Therefore, it is necessary to clarify the impact of on-demand measurement signal activation and deactivation on the classification of neighbor cell measurements on a given frequency as either co-frequency or inter-frequency measurements.

[0250] 1. If the serving cell configured with an on-demand measurement signal, or if the serving cell's corresponding frequency did not originally have a measurement RS configuration, and the measurement RS and the on-demand measurement signal are of the same type, then if an MO is configured on that frequency, the terminal needs to perform neighborhood cell measurements on that frequency.

[0251] How exactly is neighborhood cell measurement defined at this frequency, including at least one of the following methods:

[0252] 1) Regardless of whether the on-demand measurement signal is activated, as long as the on-demand measurement signal is configured on this frequency, then the neighbor cell measurement on this frequency is a co-frequency measurement. The terminal's neighbor cell measurement on this frequency must meet the co-frequency measurement criteria, specifically including cell detection criteria, RRM measurement criteria, etc. The on-demand measurement signal and the neighbor cell measurement are based on the same type of RS.

[0253] 2) During the period when the on-demand measurement signal is active at this frequency, the neighbor cell measurement at this frequency is a same-frequency measurement. The terminal's neighbor cell measurement at this frequency must meet the same-frequency measurement criteria, specifically including cell detection criteria, RRM measurement criteria, etc. The on-demand measurement signal and the neighbor cell measurement are based on the same type of RS; during the period when the on-demand measurement signal is deactivated or not yet activated, the neighbor cell measurement at this frequency is an inter-frequency measurement. The terminal's neighbor cell measurement at this frequency must meet the inter-frequency measurement criteria, specifically including cell detection criteria, RRM measurement criteria, etc. The on-demand measurement signal and the neighbor cell measurement are based on the same type of RS.

[0254] 2. If the serving cell with an on-demand measurement signal has an always-on measurement RS configuration, and the configured on-demand measurement signal and always-on measurement RS are configured on different frequencies, then the terminal can determine whether the neighborhood cell measurement is a same-frequency or different-frequency measurement based on the always-on measurement RS or the on-demand measurement signal. At least one of the following methods can be used:

[0255] 1) Neighbour cell measurements that are configured on the same frequency as the always-on measurement RS on the serving cell are defined as co-frequency measurements. Terminal measurements of neighbor cells on this frequency must meet co-frequency measurement criteria, specifically including cell detection criteria, RRM measurement criteria, etc. The on-demand measurement signal and the neighbor cell measurement are based on the same type of RS.

[0256] 2) For neighbor cell measurements configured on a different frequency than the always-on measurement RS on the serving cell, they are configured on the same frequency as the on-demand measurement signal. Regardless of whether the on-demand measurement signal is activated, neighbor cell measurements on this frequency are considered co-frequency measurements. The terminal's neighbor cell measurements on this frequency must meet co-frequency measurement criteria, specifically including cell detection criteria, RRM measurement criteria, etc. The on-demand measurement signal and the neighbor cell measurement are based on the same type of RS.

[0257] 3) For neighbor cell measurements configured on a different frequency than the always-on measurement RS on the serving cell, they are configured on the same frequency as the on-demand measurement signal. During the period when the on-demand measurement signal is active on that frequency, the neighbor cell measurement on that frequency is a co-frequency measurement. The terminal's neighbor cell measurement on that frequency must meet co-frequency measurement criteria, specifically including cell detection criteria, RRM measurement criteria, etc. The on-demand measurement signal and the neighbor cell measurement are based on the same type of RS; during the period when the on-demand measurement signal is deactivated or not yet activated, the neighbor cell measurement on that frequency is an inter-frequency measurement. The terminal's neighbor cell measurement on that frequency must meet inter-frequency measurement criteria, specifically including cell detection criteria, RRM measurement criteria, etc. The on-demand measurement signal and the neighbor cell measurement are based on the same type of RS.

[0258] Furthermore, once it is determined whether the neighbor cell measurement at a certain frequency is a same-frequency measurement or a different-frequency measurement, it is still necessary to further determine whether the measurement requires the use of a gap (measurement with in gap) or can be performed without the use of a gap (measurement without gap).

[0259] 1. If a serving cell with an on-demand measurement signal is configured, or if there is no RS configured for always-on measurement on the corresponding frequency of the serving cell, and the measurement RS and the on-demand measurement signal are of the same type, at least one of the following methods shall be used to determine whether the neighborhood cell measurement on the corresponding frequency of the serving cell needs to be performed within the gap:

[0260] 1) As long as the on-demand measurement signal is configured, regardless of whether the on-demand measurement signal is activated, if the frequency of the neighborhood cell measurement signal is completely covered by the on-demand measurement signal, the terminal can perform the measurement of the neighborhood cell measurement signal without the aid of a gap; conversely, if the frequency of the neighborhood cell measurement signal is not completely covered by the on-demand measurement signal, the terminal needs to use a gap to perform the measurement of the neighborhood cell measurement signal.

[0261] 2) It is necessary to determine whether the on-demand measurement signal is activated.

[0262] (I) During the period when the on-demand measurement signal is activated or deactivated, if the neighborhood cell measurement signal is completely covered by the on-demand measurement signal in frequency, the terminal can perform the measurement of the neighborhood cell measurement signal without the aid of a gap. If the neighborhood cell measurement signal is not covered by the on-demand measurement signal in frequency or is only partially covered, the terminal needs to use a gap to perform the measurement of the neighborhood cell measurement signal.

[0263] (II) During the period when the on-demand measurement signal is not activated or is deactivated, the terminal needs to use the gap to perform the measurement of the neighborhood cell measurement signal.

[0264] 2. If a serving cell configured with an on-demand measurement signal also has an always-on RS, and the always-on RS and the on-demand measurement signal are of the same type but configured on different frequencies, then for neighbor cell measurements configured on the frequency of the on-demand measurement signal, at least one of the following methods should be used to determine whether the neighbor cell measurement on the corresponding frequency of the serving cell needs to be performed within the gap:

[0265] 1) As long as the on-demand measurement signal is configured, regardless of whether the on-demand measurement signal is activated, if the neighborhood cell measurement signal is completely covered by the on-demand measurement signal in terms of frequency, then the terminal can perform the measurement of the neighborhood cell measurement signal without the aid of gap.

[0266] 2) It is necessary to determine whether the on-demand measurement signal is activated.

[0267] (I) During the period when the on-demand measurement signal is activated or deactivated, if the neighborhood cell measurement signal is completely covered by the on-demand measurement signal in frequency, the terminal can perform the measurement of the neighborhood cell measurement signal without the aid of a gap. If the neighborhood cell measurement signal is not covered by the on-demand measurement signal in frequency or is only partially covered, the terminal needs to use a gap to perform the measurement of the neighborhood cell measurement signal.

[0268] (II) During the period when the on-demand measurement signal is not activated or is deactivated, the terminal needs to use the gap to perform the measurement of the neighborhood cell measurement signal.

[0269] Example 3:

[0270] When a terminal performs co-frequency neighbor cell measurements on only one serving cell or the frequency of the serving cell within a band in order to save power, if an on-demand measurement signal is configured on that band, the configuration of the on-demand measurement signal, or its activation / deactivation, may affect the terminal's selection of the target neighbor cell for measurement. Specifically, this includes at least one of the following methods:

[0271] 1. For a serving cell or frequency configured with an on-demand measurement signal, if no other always-on measurement signal is configured on the serving cell or frequency, then during the deactivation period of the on-demand measurement signal or before it is activated, the neighbor cell measurement on the serving cell frequency is an inter-frequency measurement, not a co-frequency measurement, and cannot be replaced by measurements of other frequencies on the band. The neighbor cell measurement on that frequency must be included when calculating the CSSF.

[0272] 2. For a serving cell or its frequency that is configured with an on-demand measurement signal, if no other always-on measurement signal is configured on the serving cell or its frequency, then during the period when the on-demand measurement signal is active, the neighbor cell measurement on the serving cell frequency is considered a co-frequency measurement. Its priority is lower than neighbor cell measurements on the PCell or PSCell frequencies within the same band. When there are no neighbor cells on the band with PCell or PSCell frequencies to be measured, the terminal can perform that neighbor cell measurement.

[0273] 3. For a serving cell or its frequency that has an on-demand measurement signal configured, if no other always-on measurement signal is configured on the serving cell or its frequency, the neighbor cell measurement on the serving cell frequency is considered a co-frequency measurement as long as the on-demand measurement signal is configured, regardless of whether the on-demand measurement signal is active. Its priority is lower than neighbor cell measurements on the PCell or PSCell frequencies within the same band. When there are no neighbor cells on the PCell or PSCell frequencies within the band to be measured, the terminal can perform the neighbor cell measurement.

[0274] 4. The neighborhood cell measurement is a heterogeneous frequency measurement and must always be performed.

[0275] Example 4:

[0276] For a deactivated SCell, to conserve power after the on-demand measurement signal is configured or activated, the terminal may not continuously perform fast measurements based on the on-demand measurement signal cycle configuration during the period the on-demand measurement signal is active. After the on-demand measurement signal is activated until it is deactivated, the terminal performs fast measurements based on the on-demand measurement signal cycle configuration within a fast measurement window. After this fast measurement window, the terminal continues to perform measurements based on the period `measCycleSCell`. The period `measCycleSCell` is the deactivation measurement cycle configured by the base station for the terminal for that deactivated SCell. The size of the fast measurement window is determined by at least one of the following methods:

[0277] 1. The time it takes for the terminal to complete cell detection and deactivation measurement of the cell.

[0278] 1) The time required to complete cell detection for deactivation includes at least the time required for the terminal to perform N measurements based on the on-demand measurement signal, and also takes into account CSSF. intra Factors and Kp factors, if CSSF intra If the factor is greater than 1, it will further amplify the detection time. Similarly, if the Kp factor is greater than 1, it will also further amplify the detection time. N is a positive integer, predefined by the system or semi-statically configured by the base station. For example, it can be represented as: T OD-RS_sync_intra =ceil(N×K) p )×on-demand periodicity×CSSF intra T OD-RS_sync_intra =N×K p ×on-demand periodicity×CSSF intra T OD-RS_sync_intra =N×on-demand periodicity×CSSF intra T OD-RS_sync_intra =max(T2,N×K) p ×on-demand periodicity)×CSSF intra T OD-RS_sync_intra =max(T2,ceil(N×K) p )×on-demand periodicity)×CSSF intra ;

[0279] The size of T2 is predefined by the system as a number of milliseconds, such as 100ms, 200ms, etc.; T OD-RS_sync_intra The on-demand periodicity is the time it takes for the terminal to complete cell detection and deactivation measurement of the cell.

[0280] 2) The time required to complete the cell deactivation measurement includes at least the time required for the terminal to perform M measurements based on the on-demand measurement signal, and also takes into account CSSF. intra Factors and Kp factors, if CSSF intra If the factor is greater than 1, then the factor will further amplify the measurement time. If the Kp factor is greater than 1, then the factor will also further amplify the measurement time. M is a positive integer, predefined by the system or semi-statically configured by the base station. For example, it can be expressed as: TOD-RS_measurement_period_intra=ceil(M×K p )×on-demand periodicity×CSSFintra ; TOD-RS_measurement_period_intra=M×K p ×on-demand periodicity×CSSF intra ; TOD-RS_measurement_period_intra=M×on-demand periodicity×CSSF intra ; TOD-RS_measurement_period_intra=max(T2,M×K p ×on-demand periodicity)×CSSF intra ; TOD-RS_measurement_period_intra=max(T2,ceil(M×K p )×on-demand periodicity)×CSSF intra ;

[0281] Wherein, TOD-RS_measurement_period_intra is the time required to complete the deactivation cell measurement.

[0282] 2. If the first condition is met, the terminal completes one deactivation cell measurement.

[0283] 3. The time when the terminal completes the deactivation cell measurement and reports the deactivation cell measurement report.

[0284] 4. Take the minimum value of any two time lengths in 1-3 above.

[0285] 5. The terminal is configured semi-statically by the base station.

[0286] In some embodiments, the first condition includes at least one of the following:

[0287] Within the most recent T1 duration, the terminal performed cell detection on the deactivated cell. T1 can be predefined by the system or semi-statically configured by the base station to the terminal; for example, T1 may be predefined as 5 seconds.

[0288] Within the frequency band where the deactivated cell is located, there exists another PCell, PSCell, or SCell that is in an active state.

[0289] Within the frequency band of the deactivated cell, there exists another PCell, PSCell, or SCell that is in an active state, and the frequency range of the PCell, PSCell, or SCell is continuous with the frequency range of the deactivated cell in the frequency domain.

[0290] In some embodiments, the starting point of the rapid measurement window is determined according to at least one of the following:

[0291] The moment when the terminal receives the activation information of the on-demand measurement signal;

[0292] The moment when the terminal first receives the on-demand measurement signal after receiving the activation information of the on-demand measurement signal;

[0293] The moment when the terminal receives the activation information of the on-demand measurement signal and completes processing;

[0294] The moment when the terminal receives the activation information of the on-demand measurement signal for the first time and completes the processing.
