For example, the UE can act as a scheduling entity, providing sidelink signals between UEs in V2X or D2D, etc. For example, cellular phones and cars communicate with each other using sidelink signals. Cellular phones and smart home devices communicate without relaying communication signals through a base station.

[0037] The network device in this application embodiment can be a device for communicating with a terminal device. This network device can also be called an access network device or a wireless access network device, such as a base station. In this application embodiment, the network device can refer to a radio access network (RAN) node (or device) that connects the terminal device to the wireless network. A base station can broadly encompass, or be replaced by, various names including: NodeB, evolved NodeB (eNB), next-generation NodeB (gNB), relay station, transmitting and receiving point (TRP), transmitting point (TP), master MeNB, auxiliary SeNB, multi-mode radio (MSR) node, home base station, network controller, access node, wireless node, access point (AP), transmission node, transceiver node, baseband unit (BBU), remote radio unit (RRU), active antenna unit (AAU), remote radio head (RRH), central unit (CU), distributed unit (DU), positioning node, etc. A base station can be a macro base station, micro base station, relay node, donor node, or similar, or a combination thereof.

[0041] It should be understood that all or part of the functions of the communication device in this application can also be implemented by software functions running on hardware, or by virtualization functions instantiated on a platform (e.g., a cloud platform).

[0042] RRM measurement configuration

[0043] Terminal equipment can perform RRM measurements according to the measurement configuration of RRM measurement. The measurement configuration of RRM measurement can include intra-frequency measurement configuration, inter-frequency measurement configuration, and inter-radio access technology (inter-RAT) measurement configuration. Inter-RAT measurement configuration can also be referred to as or understood as inter-system measurement configuration.

[0044] Same-frequency measurement configurations can be used for same-frequency measurements. Same-frequency measurement means that the frequency point measured by the terminal device is the same as the frequency point (center frequency) of the serving cell of the terminal device. Different-frequency measurement configurations can be used for different-frequency measurements. Different-frequency measurement means that the frequency point measured by the terminal device is different from the frequency point of the serving cell of the terminal device. Different-system measurement configurations can be used for different-system measurements. Different-system measurement means that the frequency point measured by the terminal device is in a different system than the frequency point of the serving cell of the terminal device. Figures 2 to 4 show the measurement types corresponding to different measurement reference signals. Figures 2 and 3 are examples of measurement types corresponding to the synchronization signal block (SSB) as the measurement reference signal. In the examples of Figures 2 and 3, the measurements of cell 1 and cell 2 by the terminal device are same-frequency measurements, while the measurement of cell 3 by the terminal device is a different-frequency measurement. Figure 4 is an example of the measurement type corresponding to the channel state information reference signal (CSI-RS) as the measurement reference signal. In the example in Figure 4, the measurements taken by the terminal device for cell 1 and cell 2 are in-frequency measurements, while the measurements taken by the terminal device for cell 3 are out-of-frequency measurements.

[0045] The measurement configuration for RRM measurements may include one or more of the following: measurement target, reporting configuration, measurement identifier, reference signal configuration, measurement interval (gap) configuration, etc. In some embodiments, the reporting configuration can be used to configure the relevant settings for the terminal device to report measurement results. For example, the reporting configuration may include one or more of the following: reporting type (such as periodically triggered reporting, event-triggered reporting), condition-triggered configuration, cell global identifier (CGI) reporting, etc.

[0046] In some embodiments, the measurement configuration for RRM measurements can be carried in radio resource control (RRC) signaling. For example, a network device can send the RRM measurement configuration to a terminal device via RRC signaling over the air interface. The terminal device can then measure the cell signal based on this configuration and report the measurement results to the network device according to the reporting configuration, allowing the network device to make decisions such as handover. It should be noted that the embodiments of this application do not limit the measurement quantities measured by the terminal device. Exemplarily, the measurement quantities measured by the terminal device may include one or more of the following: reference signal received power (RSRP), reference signal received quality (RSRQ), and signal to interference plus noise ratio (SINR).

[0047] To facilitate understanding, the following example uses the NR system to illustrate the measurement configuration for RRM measurements. In the NR system, the measurement configuration for RRM measurements can be indicated using the parameter MeasConfig. As one implementation, MeasConfig can be configured via RRC signaling Measgapconfig and MeasObjectNR(MO), i.e., gap configuration and MO addition.

[0048] MeasConfig includes information such as: measurement target (measObject), reporting configuration (reportConfig), measurement identifier (measId), reference signal configuration (s-MeasureConfig), and measurement interval configuration (measGapConfig). The specific information elements included in MeasConfig are shown below.

[0049] The specific information elements included in the reporting configuration (reportConfig) in the NR system are shown below.

[0050] RRM measurement reference signal

[0051] For wireless mobile communication systems, accurate measurement of cell quality and beam quality is fundamental to the effective execution of radio resource management and mobility management. For 5G NR, two main types of reference signals (RS) are currently considered for measurement: SSB and CSI-RS.

[0052] For SSB measurements, network devices can configure SSB measurement resources (i.e., SSB-based measurement configurations) for terminal devices via higher-layer signaling, enabling the terminal devices to perform corresponding measurement operations. The SSB-based measurement configurations configured by the network device for the terminal device are shown in Figure 5. As shown in Figure 5, the network device can configure one or more SSB-based measurement configurations for the terminal device. Each SSB-based measurement configuration may include one or more of the following configurations: SSB frequency point, SSB subcarrier spacing, SSB measurement timing configuration (SMTC), and reference signal configuration. It should be understood that SSB-based measurement configurations may include other configurations besides those listed above; these other configurations will not be detailed in this embodiment.

[0053] The SSB frequency point mentioned above refers to the center frequency point location of the SSB to be measured.

[0054] The aforementioned SSB subcarrier spacing refers to the subcarrier spacing information of the SSB. This application does not limit the SSB subcarrier spacing in its embodiments. For example, the SSB subcarrier spacing may include one of the following: 15kHz, 30kHz, 60kHz, 120kHz, etc.

[0055] The aforementioned SMTC refers to the time-domain resource configuration information for SSB measurements. Network devices can configure one or more SMTCs (such as a first SMTC, a second SMTC, etc.) for terminal devices within a single measurement configuration. SMTCs are primarily used to configure a set of measurement time windows based on SSB measurements. Network devices can configure (or adjust) parameters such as the size, position, and period of this measurement time window for the terminal device through the SMTC. For example, referring to Figure 6, the network device can configure the size (e.g., 5 milliseconds), period (e.g., 40 milliseconds), and time-domain position of this measurement time window through the SMTC. It should be noted that SSBs other than those configured by the terminal device are not considered for RRM measurements.

[0056] The aforementioned reference signal configuration may include an SSB configuration and / or a CSI-RS configuration. In an SSB-based measurement configuration, the reference signal configuration includes an SSB configuration. This SSB configuration may include one or more of the following indication information: SSB indication to be measured, auxiliary timing information indication, and received signal strength indication (RSSI) measurement configuration.

[0057] RRM measurement interval

[0058] RRM measurement gaps (or simply gaps) can be used by terminal devices to perform RRM measurements, such as inter-frequency RRM measurements. In some embodiments, the configuration of the gap is related to the frequency range (FR) supported by the terminal device. Taking an NR system as an example, the operating frequency range of the terminal device includes not only FR1 below 6 GHz but also the millimeter-wave band FR2 above 6 GHz. Depending on whether the terminal device supports FR1 / FR2, the gap can include gaps per terminal device (per UE) and gaps per FR, that is, gaps can include gapFR1, gapFR2, and gapUE.

[0059] In some embodiments, the terminal device also introduces an independent gap capability indicator, which can be used to indicate whether gaps of different frequency ranges can be configured, for example, whether gaps per FR1 / per FR2 can be configured. In some embodiments, if the terminal device supports the independent gap capability, then the corresponding FR1 and FR2 measurements of the terminal device can be performed independently and without affecting each other.

[0060] In some embodiments, capability indication can be provided via the parameter independentGapConfig.

[0061] The parameter configuration for RRM measurement intervals generally includes one or more of the following parameters: measurement gap length, measurement gap repetition period, measurement gap timing advance, and gap offset. Measurement gap length (MGL) characterizes the length of the measurement interval. Measurement gap repetition period (MGRP) characterizes the period of the measurement interval. Measurement gap timing advance (MGTA) characterizes the timing advance of the measurement interval. Gap offset characterizes the time-domain offset of the measurement interval, with a value ranging from 0 to MGRP-1.

[0062] The value ranges of each parameter in the RRM measurement interval configuration are shown in Table 1. As shown in Table 1, the value ranges for MGL are 1.5 milliseconds (ms), 3 ms, 3.5 ms, 4 ms, 5.5 ms, and 6 ms. The value ranges for MGRP are 20 ms, 40 ms, 80 ms, and 160 ms. The value range for MGTA is 0 ms, 0.25 ms, and 0.5 ms. The interval offset ranges from 0 to 159, and the maximum value of the interval offset does not exceed the configured MGRP.

[0063] Table 1

[0064] The terminal device can determine (e.g., calculate) the system frame number (SFN) and subframe number of the first subframe in each measurement interval based on the RRM measurement interval parameter configuration. Here, SFN mod T = FLOOR(gapOffset / 10), T = MGRP / 10, and subframe number = gapOffset mod 10. The terminal device needs to initiate the measurement before the MGTA in the first subframe of that measurement interval.

[0065] RRM measurement intervals can correspond to one or more gap patterns, which can be used to indicate RRM measurement interval configurations. For example, one gap pattern can correspond to one MGL and one MGRP. As shown in Figure 7, in the NR system, RRM measurement intervals can include 24 gap patterns, of which gap patterns 0-11 can be used for FR1 measurement interval configurations, and gap patterns 12-23 can be used for FR2 measurement interval configurations.

[0066] RRM measurement time requirements

[0067] The RRM measurement time requirements for terminal devices may differ depending on their RRC state. The following sections describe the RRM measurement time requirements for terminal devices in RRC idle / inactive states and RRC connected states. First, we will describe the RRM measurement time requirements for terminal devices in RRC idle / inactive states.

[0068] For terminal devices in the RRC idle / inactive state, performing RRM measurements can be used for cell reselection. The types of RRM measurements for terminal devices in the RRC idle / inactive state are described below with reference to Figure 8.

[0069] Figure 8 illustrates the NR system (or E-UTRA) as an example. As shown in Figure 8, taking mobility in the RRC idle state under the standalone network deployment mode as an example, the measurement types can be divided according to the relationship between the measurement frequency and the frequency of the serving cell: measurement and evaluation of serving cell, measurements of intra-frequency NR( / E-UTRA) cells, measurements of inter-frequency NR( / E-UTRA) cells, and measurements of inter-RAT NR( / E-UTRA) cells.

[0070] Serving cell measurement and evaluation refers to measuring the frequency of the serving cell, i.e., the frequency of the current serving terminal device. Taking Figure 8 as an example, serving cell measurement and evaluation may include the measurement of frequency 1 (f1) / frequency 2 (f2) of NR terminal device 1, or the measurement of frequency 1' (f1') of NR terminal device 2, or the measurement of frequency 4 (f4) of dual-connectivity terminal device in NR system or frequency 5 (f5) in E-UTRA system.

[0071] Intra-frequency measurement, also known as intra-band measurement, refers to measuring different frequency points within the same frequency band. Taking Figure 8 as an example, intra-band measurement can include the measurement of f1 and f1' by a terminal device (such as terminal device 1 or terminal device 2) in NR cell 1.

[0072] Inter-band cell measurement, also known as inter-frequency measurement, refers to measuring different frequency points within different frequency bands. Taking Figure 8 as an example, inter-band cell measurement can include the measurement of f3 / f4 by terminal device 2.

[0073] Inter-system measurement (i.e., cross-system measurement) refers to measuring the frequency points of networks with different standards, such as measuring the frequency points of different standards like GSM / WCDMA / E-UTRA / NR. Taking Figure 8 as an example, inter-system measurement can include the measurement of f5 in the E-UTRA system by terminal device 1 or terminal device 2.

[0074] Figure 9 shows the measurement time window of a terminal device in an idle or inactive state. As can be seen from Figure 9, the measurement time window of a terminal device in an idle or inactive state needs to satisfy T... detect T measure T evaluate Measurement time requirements. The following example uses same-frequency measurement in an NR system to illustrate the T... detect T measure T evaluate The parameters will be introduced, and the corresponding T values ​​for other measurement types will also be discussed. detect T measure T evaluate The definitions of other parameters are similar and will not be repeated here.

[0075] In intra-frequency measurement scenarios, the terminal device can identify new intra-frequency cells and measure the synchronization signal RSRP (SS-RSRP) and synchronization signal RSRQ (SS-RSRQ) at a specified frequency. The terminal device can then evaluate whether a newly detectable intra-frequency cell meets the cell reselection criteria. The detection time of the terminal device is T. detect,NR_Intra The terminal equipment can measure the SS-RSRP and SS-RSRQ of intra-frequency cells, with a measurement period of T. measure,NR_Intra .

[0076] In some embodiments, for co-frequency cells that have been detected but not yet reselected, the terminal device should evaluate the measurement data of the cell for filtering within the Tevaluate,NR_Intra time period.

[0077] In some embodiments, the terminal device needs to filter the SS-RSRP and SS-RSRQ (at least two sets) of each measured co-frequency cell, and these at least two sets of measurements should be spaced at least T apart. measure,NR_Intra / 2 This period of time.

[0078] In some embodiments, if the serving cell indicates (e.g., in the measurement and control system information) that the terminal device undergoing cell reselection does not perform neighbor cell measurements, then the terminal device does not consider the frequency point measurement of neighbor cells.

[0079] For terminal devices in RRC connected state, the measurement types performed by the terminal device can include same-frequency measurement, different-frequency measurement, and different-system measurement. Among these, for same-frequency measurement, the RRM measurement of the terminal device can include measurements requiring a gap and measurements without a gap. Table 2 shows the measurement period corresponding to FR1 measurements without a gap. Table 3 shows the measurement period corresponding to FR1 measurements with a gap. As can be seen from Tables 2 and 3, the measurement periods corresponding to measurement scenarios without a gap and measurement scenarios with a gap are different. Taking the FR1 scenario without configured discontinuous reception (DRX) as an example, the measurement period corresponding to the scenario without a gap is max(200ms, ceil(5*Kp)*SMTC period)*CSSF. intra The measurement period for scenarios requiring a gap is max(200ms, 5*max(MGRP, SMTC period))*CSSF. intra .

[0080] Table 2

[0081] Table 3

[0082] As can be seen from the above description, terminal equipment can scale the RRM measurement time. Taking SSB-based measurements as an example, measurement time scaling can be divided into two categories: one is measurement time scaling applicable only to measurements without gaps, and this scaling factor is characterized by Kp; the other is time scaling applicable to multi-carrier measurements within and outside gaps for terminal equipment with carrier aggregation capabilities, and this scaling factor is characterized by the carrier-specific scaling factor (CSSF). The CSSF can be applied to relax the measurement time (including cell identification and measurement period) for various intra-frequency or inter-frequency measurements.

[0083] In some embodiments, the measurement time scaling is to meet certain measurement accuracy requirements (such as the measurement accuracy of RSRP, RSRQ, and SINR). Among them, when the terminal device performs intra-frequency measurement or inter-frequency measurement, it needs to obtain sufficient reference signal samples within the unit measurement time, and report the relevant measurement results to the network device after evaluating them. Since the intra-frequency measurement or inter-frequency measurement supports measurements with or without configuring gaps, therefore, the corresponding SMTC and gaps may not completely overlap. FIG. 10 shows the relationship between SMTC and gaps. It can be seen from FIG. 10 that SMTC and gaps may completely overlap, partially overlap, or not overlap.

[0084] Considering the overlapping relationship between the current SMTC and the gaps configured by the network device (such as per-terminal-device or per-FR gaps), there are three cases of non-overlap, complete overlap, or partial overlap between the length (and / or period) of the measurement reference signal and the length (and / or period) of the gaps. Therefore, the measurement period needs to define different requirements for scaling time respectively to meet the measurement accuracy requirements.

[0085] In some embodiments, the definition of the measurement time scaling factor Kp applicable to intra-frequency measurement (or inter-frequency measurement) without gaps satisfies the following conditions. If the SMTC is entirely within the gap or entirely outside the gap, then the intra-frequency measurement without measuring the gap is either entirely within the gap or entirely outside the gap, and no additional relaxation is required, that is, Kp = 1. If the SMTC and the gap partially overlap and the SMTC period < MGRP, then the intra-frequency measurement without gaps needs to lengthen the measurement time to ensure a sufficient number of samples of the measurement reference signal. In this case, the lengthening factor Kp = 1 / (1 - (SMTC period / MGRP)). For the case where the SMTC and the gap partially overlap and the SMTC period > MGRP, the protocol does not clearly define the time requirements for the terminal device to measure, which belongs to the scope of terminal device implementation.

[0086] In some embodiments, for the time scaling of multi-carrier measurements inside and outside the gap, according to the measurements outside the gap and the measurements inside the gap (including intra-frequency measurement or inter-frequency measurement), the time scaling factor can be divided into CSSF outside_gap and CSSF within_gap .

[0087] CSSF outside_gap is applicable to terminal devices that allow measurements outside the gap. CSSF outside_gap refers to the relaxation adjustment of the measurement time of the terminal device when the SMTC configured for the measurement without gaps of the terminal device partially overlaps or does not overlap with the gap configured for the current terminal device.

[0088] When a terminal device has carrier aggregation (CA) capability, it is assumed that the terminal device can handle measurements of a maximum of two carriers simultaneously. When the terminal device needs to simultaneously measure the same, different, or different system frequencies of multiple carriers, a scaling factor (CSSF) for the measurement time can be defined based on the number of carriers being measured. outside_gap This is used to relax the measurement time for measurements at the same or different frequencies. Taking the independent network deployment mode as an example, Table 4 gives the corresponding measurement time relaxation factor (CSSF) on the FR1 or FR2 primary or secondary carriers. outside_gap For requirements under other modes, please refer to section 9.1.5.1 of TS 38.133.

[0089] Table 4

[0090] CSSF within_gap This method is applicable to measurements where the terminal equipment requires a gap configuration, or to measurements at the same or different frequency points that do not require a gap. In cases where the configured SMTC completely overlaps with the gap configuration of the current PE terminal equipment or per FR, the measurement time of the terminal equipment is relaxed and adjusted. The gap-sharing scheme (measGapSharingScheme) configured on the current terminal equipment, and the number of same-frequency or different-frequency measurement objects that need to be measured within the gap, jointly determine the CSSF. within_gap For example, when the gap sharing scheme is evenly distributed, the scaling factors for same-frequency and different-frequency measurements are the same, and the CSSF corresponding to measurement object i is... within_gap,i This represents the maximum number of objects (max(M)) configured in the same gap as the measured object i within 160ms (maximum {160 / MGRP-1} gaps). tot,i,j The product of ()) and Ri, where Ri represents the ratio of the number of gaps configured for the measurement object i to the number of gaps removed for positioning measurements used in a specific configuration. It should be noted that these positioning measurement gaps are considered separately (related specific configuration requirements can be found in section 9.1.5.2 of protocol specification TS 38.133). Similarly, when configuring other measurement gap sharing schemes, the scaling factors for corresponding same-frequency and different-frequency (or different-system) measurement times can be obtained, and then the measurement time scaling (CSSF) within the gap for same-frequency and different-frequency (or different-system) measurement objects can be calculated separately. within_gap .

[0091] Some RRM measurements are based on activation or trigger signals. How to configure such measurement processes is a problem that needs to be solved. To address the above problem, the embodiments of this application are described in detail below.

[0092] Figure 11 is a schematic flowchart of a communication method provided in one embodiment of this application. The method in Figure 11 is described from the perspective of the interaction between a terminal device and a network device. The terminal device and network device can be, for example, the terminal device and network device described in Figure 1.

[0093] Referring to Figure 11, in step S1110, the terminal device receives a first configuration message sent by the network device. The first configuration message can be used to trigger a first signal. Alternatively, the first configuration message can be used to configure the first signal. Or, the first configuration message can be used to activate the first signal. The first configuration message can be, for example, an RRC message, a media access control element (MAC CE), or downlink control information (DCI). For example, the first configuration information can be called an activation indication for the first signal. Based on the first configuration message, the first signal can be activated on demand, allowing the terminal device to perform measurements as needed, which helps to save energy. It should be understood that after the network device sends the first configuration message to the terminal device, the network device can begin sending the first signal to the terminal device.

[0094] A first signal can be used by the terminal device to perform (or initiate) a first measurement. This first signal can be, for example, a reference signal (RS), or other types of signals that can be used by the terminal device for measurement. For example, the first signal can be an SSB.

[0095] The first signal is sent upon configuration, triggering, or activation by the first configuration message; therefore, the first signal can be called an on-demand (OD) signal. For example, the first signal could be OD-RS. Exemplarily, the first signal could be OD-SSB.

[0096] The first measurement mentioned above can be, for example, a fast measurement or a fast-mode measurement. It should be understood that the first measurement can be a measurement performed by the terminal device for a specific cell. For example, the first measurement can be a measurement performed by the terminal device for a secondary cell (SCell). For example, the secondary cell may be in a deactivated state, and the first measurement is used to determine whether the secondary cell is activated. Exemplarily, the first measurement is a fast measurement performed by the terminal device on a deactivated secondary cell, and this fast measurement is initiated based on the activation of the OD-SSB. Alternatively, the first measurement can also be a measurement performed by the terminal device for a primary secondary cell (PSCell).

[0097] It should be understood that the first measurement mentioned in the embodiments of this application can be a layer-1 measurement or a layer-3 measurement.

[0098] The first measurement can be performed within a first time window. The first time window refers to the time window used to perform the first measurement. For example, this first time window is called a fast window or a fast mode window. The length of the first time window can be set such that the terminal device measures a sufficient number of first signals to meet the corresponding measurement requirements. As one implementation, it can be specified that the network device does not allow the activation of first signals (such as OD-SSBs) within the time range corresponding to the first time window, so that the terminal device measures a sufficient number of first signals to meet the corresponding measurement requirements. The length of the first time window can, for example, be determined based on the number of first signals (such as OD-SSBs). Taking Figure 12 as an example, the network device can send an OD-SSB activation command to the terminal device to trigger the terminal device to perform a fast measurement within the fast window.

[0099] In some implementations, the terminal device can receive a second configuration message (or a first time window configuration message) sent by the network device. The second configuration message can be an RRC message, or the second configuration information can be a MAC CE or DCI. This second configuration message can be used to configure one or more of the following: the length of the first time window and / or the period of the first time window. The definition of the length of the first time window is given above. The period of the first time window can be used to indicate the time interval between two adjacent first time windows. Therefore, the period of the first time window can also be called the interval of the first time window. In cases where multiple first measurements are required (or where there are multiple shots within the first time window), configuring the period of the first time window can help the terminal device quickly determine the temporal location of the next shot of the first window.

[0100] The second configuration information may include time-domain location information for one or more first time windows. When multiple first time windows are configured in the second configuration information, the terminal device can perform multiple first measurements within these multiple first time windows, which helps the network device make better decisions. The one or more first time windows may be part or all of the first time windows within a period of the first time window. For example, the one or more first time windows may include the first first time window and / or the second first time window within a period of the first time window. Alternatively, the one or more first time windows may include each first time window within a period of the first time window.

[0101] The time-domain location information of the one or more first time windows may include or indicate one or more of the following: the time-domain start position (or origin, or start time) of the one or more first time windows, the time-domain end position (or end point, or end time) of the one or more first time windows, and the time offset associated with the time-domain start position of the one or more first time windows.

[0102] For example, the one or more first time windows may include a second first time window within the period of the first time window. The time-domain start position of the second first time window may be determined based on one or more of the following: the time-domain start position of the first first time window within the period of the first time window, the period of the first time window, the time offset, and the transmission time of the first signal.

[0103] In one implementation, the time-domain starting position of the second first time window is determined based on the first time-domain position. The first time-domain position refers to the time-domain position obtained by adding one period of the first time-domain period to the time-domain starting position of the first first time window. For example, the time-domain starting position of the second first time window is this first time-domain position.

[0104] In another implementation, the time-domain start position of the second first time window is determined based on the first time-domain position and a time offset. For example, the time-domain start position of the second first time window is equal to the sum of the first time-domain position and the time offset, or the time-domain start position of the second first time window is equal to the difference between the first time-domain position and the time offset. This application does not specifically limit the unit or definition of the time offset. For example, the time offset can be tms (t is a positive integer greater than or equal to 1). Alternatively, the time offset can include one or more transmission cycles of the first signal. Or, the time offset can include one or more symbols. Or, in some implementations, the time offset can be the time offset of the second first time window relative to the transmission time of the second configuration message.

[0105] In some implementations, the terminal device may receive a third configuration message (or resource configuration message for the first signal) sent by the network device. This third configuration information may, for example, be an RRC message. This third configuration message can be used to configure one or more of the following: the time-domain position of the first signal, the frequency-domain position of the first signal, the spatial position of the first signal, the index of the first signal, and measurement time information for the second measurement.

[0106] Taking the first signal as OD-SSB as an example, the third configuration message can be used to configure one or more of the following: SSB frequency, SSB periodicity (e.g., 5 to 160 ms), SSB burst positioning, and SSB index.

[0107] The second measurement mentioned above refers to a different measurement from the first measurement. For example, the first measurement is a fast measurement or a fast-mode measurement, while the second measurement can be a slow measurement. Exemplarily, the first measurement is a fast measurement or a fast-mode measurement performed by the terminal device when deactivating a secondary cell; the second measurement is a measurement associated with the meascycleScell ​​performed by the terminal device when deactivating a SCell. Alternatively, both the first and second measurements can be measurements for a PSCell. It should be understood that the second measurement mentioned in the embodiments of this application can be a layer 1 measurement or a layer 3 measurement.

[0108] The measurement timing information mentioned above for the second measurement may include, for example, the time-domain measurement period for the second measurement. This measurement timing information for the second measurement may include one or more of the following: SSB measurement timing configuration (SMTC), SCell measurement period (meascycleScell, used to configure the time period for SCell to perform measurements in a deactivated state), or discontinuous reception (DRX). The time-domain measurement period for the second measurement may, for example, be 160 ms.

[0109] In some implementations, after the first configuration message configures, triggers, or activates the first signal, the terminal device can receive the first signal according to the third configuration message. For example, the first configuration message is a MAC CE or DCI, and the third configuration message is an RRC message. The terminal device can first receive the RRC message, at which point the first signal is in a deactivated state. After receiving the MAC CE or DCI (indicating that the first signal is activated), the terminal device receives the first signal according to the time-domain measurement period configured in the RRC message.

[0110] In some implementations, the terminal device receives a fourth configuration message (or a deactivation message for the first signal) sent by the network device. This fourth configuration message can be an RRC message, a MAC CE, or a DCI. The fourth configuration message can be used to deactivate or reconfigure the first signal. For example, the fourth configuration message is a MAC CE, and the first signal is OD-SSB. The terminal device receives this MAC CE sent by the network device, which indicates that OD-SSB is deactivated.

[0111] This application does not specifically limit the method for determining the start time of the first measurement in its embodiments. In some implementations, the start time of the first measurement is determined based on one or more of the following: the transmission time (or reception time) of the first configuration message, the processing time of the terminal device, and a first time window (which can be configured based on the second configuration information mentioned above, as described above). The processing time of the terminal device may include one or more of the following: signaling processing time after the terminal device receives the first configuration message (such as MAC CE), baseband processing time, and measurement preparation time. For example, after receiving the first configuration message (such as MAC CE), the terminal device waits for signaling processing, baseband processing, and preparation time before starting to receive and measure the first first signal, thereby performing the first measurement. Alternatively, the terminal device may perform the first measurement according to a first time window (e.g., starting the first measurement at the beginning of the first time window).

[0112] In some implementations, the measurement time of the first measurement mentioned above needs to meet a first measurement time requirement (or first measurement delay requirement). This first measurement time requirement can be determined based on one or more of the following: a first time window (the time window for performing the first measurement), N transmission periods of the first signal (N is a positive integer greater than or equal to 1), and a first threshold value (which can be determined based on protocol predefined information, preconfiguration information, and / or network device configuration information, for example, 200ms). In one implementation, the first measurement time requirement is determined based on at least two of the first time window, N transmission periods of the first signal, and the first threshold value. For example, the first measurement time requirement is determined based on the maximum value of at least two of the first time window, N transmission periods of the first signal, and the first threshold value. Exemplarily, the first measurement time requirement is determined based on the first time window, N transmission periods of the first signal, and the first threshold value, such as the maximum value of the first time window, N transmission periods of the first signal, and the first threshold value. As a more concrete example, assuming the first signal is OD-SSB, the first threshold value is 200ms, and the first measurement is a fast measurement, then the measurement time (or measurement delay) for the terminal device to perform the fast measurement needs to satisfy the maximum value of N OD-SSB cycles, 200ms, and the time window of the fast measurement.

[0113] The first measurement has been described in detail above. In addition to the first measurement, the terminal device can also perform a second measurement after the first time window (fast measurement window) ends (or after the first measurement ends). Alternatively, during an activation / deactivation process of the first signal (such as OD-SSB), a second measurement can be performed after the first time window. The second measurement mentioned here refers to a different measurement from the first measurement. For example, the first measurement may be a fast measurement or a fast-mode measurement, while the second measurement can be a slow measurement (such as a measurement based on the meascycleScell ​​configured by the network device). For instance, the first measurement is a fast measurement or a fast-mode measurement performed by the terminal device during the deactivation of the SCell, and the second measurement is a slow measurement performed by the terminal device during the deactivation of the SCell according to the meascycleScell ​​configured by the network device. After the first time window (fast measurement window), if the OD-SSB is still active from the terminal device's perspective, the terminal device can continue to perform the second measurement (such as a slow measurement) to meet the measurement requirements of traditional deactivation secondary cells. Taking Figure 12 as an example, the network device can send an OD-SSB activation command to the terminal device to trigger the terminal device to perform a fast measurement (corresponding to the first measurement) within a fast window. After the first measurement, since the OD-SSB is still active, the terminal device can continue to perform a slow measurement (corresponding to the second measurement), which can be performed within a slow window (or slow measurement window). This slow window can be, for example, equal to N1 * measCycleSCell (N1 is a positive integer greater than or equal to 1).

[0114] After the first time window ends, the terminal device can perform the second measurement if the first condition is met. The first condition can include one or more of the following: after the first time window ends, the first signal is not deactivated (or the first signal is still being transmitted); a second signal exists that can be used for the second measurement. For example, the first condition could include that the first signal is not deactivated after the first time window ends. In this case, the terminal device can continue to perform the second measurement based on the first signal. Alternatively, if the first signal is deactivated after the first time window ends, but a second signal exists that can be used for the second measurement (such as an always-on second measurement reference signal), the terminal device can also continue to perform the second measurement.

[0115] In some implementations, the measurement time of the second measurement mentioned above needs to meet a second measurement time requirement (or a second measurement latency requirement). This second measurement time requirement can be determined based on one or more of the following: M time-domain measurement periods for the second measurement (M being a positive integer greater than or equal to 1), and a second threshold value. The time-domain measurement period for the second measurement can be, for example, the time-domain measurement period configured by the third configuration information mentioned above, such as SMTC, meascycleScell, or DRX.

[0116] As mentioned earlier, after receiving the first configuration information, the terminal device performs a first measurement and / or a second measurement. In some implementations, the terminal device may be allowed to stop the measurement (first measurement and / or second measurement) if certain conditions (hereinafter referred to as the second condition) are met. The second condition can be set according to the actual situation, and the specific implementation of the second condition will be illustrated in detail below.

[0117] In one implementation, the second condition is associated with whether the first signal is deactivated. For example, if the first signal is deactivated (the first signal can be deactivated based on the aforementioned fourth configuration message, which could be, for example, MAC CE or DCI), the terminal device can be allowed to stop the measurement. For example, as mentioned earlier, after the first time window, the terminal device can continue to perform the second measurement. During the execution of the second measurement, if the first signal is deactivated (e.g., upon receiving the aforementioned fourth configuration message), the terminal device can stop the measurement (the second measurement). In this case, the terminal device's measurement does not need to meet any measurement time requirements (or measurement latency requirements). After the first signal is deactivated, the network device may still send a second signal (e.g., always on signal). In this case, as a possible implementation, the terminal device chooses to stop the measurement even if the network device is still sending the second signal. Alternatively, as another possible implementation, if the second signal exists, the terminal device can continue to perform the second measurement. Or, as yet another possible implementation, if the first signal is deactivated but the second signal exists, whether to continue performing the second measurement can be determined by the implementation of the terminal device.

[0118] In another implementation, the second condition is associated with the period of the first time window (the first time window and its period are described above and will not be detailed here). For example, if the measurement time (or measurement delay of the second measurement) of a second measurement performed after the first measurement (or after the first time window) reaches a first time (a time determined based on the period of the first time window, such as equal to the end time of the first time window plus the time corresponding to the period of the first time window), the terminal device can be allowed to stop the measurement. Exemplarily, if the end time of the first time window plus the measurement time of the second measurement exceeds the first time (such as equal to the end time of the first time window plus the time corresponding to the period of the first time window), the terminal device is allowed to stop the measurement. In this case, the measurement by the terminal device does not need to meet any measurement time requirement (or measurement delay requirement).

[0119] In another implementation, the second condition is associated with the first time interval. The first time interval can be determined based on protocol predefined information, preconfiguration information, and / or network device configuration information (such as RRC messages). This first time interval can, for example, be the same as or different from the period of the first time window mentioned above. Alternatively, the first time interval can be equal to x seconds (x is a positive integer greater than or equal to 1) or equal to y DRX cycles (y is a positive integer greater than or equal to 1). For example, the first time interval can be equal to max(5s, 5 * DRX cycles), i.e., the maximum of 5s and 5 DRX cycles. The first time interval can be a time threshold, or it can be determined based on the duration of a timer. For example, if the measurement time (or measurement delay of the second measurement) of a second measurement performed after the first measurement (or after the first time window) reaches the second time (the time determined based on the first time interval), the terminal device is allowed to stop the measurement. In this case, the terminal device's measurement does not need to meet any measurement time requirement (or measurement delay requirement). As mentioned above, the first signal can be an OD-SSB, and the first measurement can be used to deactivate the SCell measurement. In this scenario, the first time interval can be understood as the expected time gap between the activation command of the first signal (corresponding to the first configuration message mentioned above) and the activation command of the secondary cell. The specific reasons for this stipulation are as follows: The introduction of OD-SSB is for network energy saving. However, from the perspective of the terminal device, the dynamic activation, transmission, and deactivation of the first signal (such as OD-SSB) may not bring much network energy saving gain. Instead, it may cause the terminal device to consume more energy due to the need to continuously perform RF and baseband on / off operations. After the terminal device performs a rapid measurement, it can send a measurement report to the network device. After receiving the measurement report, the network device can decide whether to immediately activate the SCell or deactivate the OD-SSB to save energy. If the time interval between the SCell activation command and the OD-SSB activation command is very large, then this setting is meaningless from both the perspective of network energy saving and terminal device energy saving. Based on the above considerations, this embodiment proposes the aforementioned first time interval. If no SCell activation command is received after the first time interval (which can be called the maximum time interval, such as max(5s, 5*DRX period)) from the OD-SSB activation command, the terminal device is allowed to stop the measurement until the next first time window arrives.

[0120] As an example, referring to Figure 13, after the network device sends an OD-SSB activation command to the terminal device, it begins OD-SSB transmission. Upon receiving the OD-SSB activation command, the terminal device also begins performing fast measurements within the fast window. After the fast window ends, the terminal device enters the slow window and begins slow measurements. The time range indicated by the dashed box in Figure 13 is the first time interval mentioned earlier, which represents the expected time interval between the OD-SSB activation command and the SCell activation command. As can be seen from Figure 13, the terminal device does not receive the SCell activation command within the first expected time interval. In this case, even if the OD-SSB is not deactivated, the terminal device stops measuring until the OD-SSB is activated (or reactivated) again.

[0121] It should be noted that the above provides several ways to implement the terminal device stopping measurement. These methods can be implemented individually or in combination. For example, the terminal device continues to perform a second measurement after the first time window. If the first signal is deactivated, and / or if the measurement time of the terminal device reaches the end time of the first time window plus the time corresponding to the first time interval, then the terminal device stops measuring.

[0122] The second time mentioned above could be, for example, the time corresponding to the increase of the first time interval from the start of the third time interval. This third time could be determined based on the activation time of the first signal (e.g., equal to the activation time of the first signal). Alternatively, the third time could also be determined based on the start time of the first time window (e.g., equal to the start time of the first time window). For example, starting from the third time, if the measurement time of the terminal device exceeds a time threshold (used to indicate the first time interval), the terminal device stops measuring. Or, starting from the third time, the terminal device starts a timer (the timing duration corresponding to the aforementioned first time interval); if the timer expires, the terminal device stops measuring.

[0123] In some implementations, the terminal device can receive a fifth configuration message (or a first time window reconfiguration message) sent by the network device. This fifth configuration message can be a MAC CE, an RRC message (such as an RRC reconfiguration message), or a DCI. This fifth configuration message is used to configure or reconfigure the first time window (for the first measurement, see previous section for details) after the first signal is triggered or activated and before it is deactivated. As described above, after the first signal is triggered or activated, the terminal device will perform the first measurement within the first time window. This fifth configuration message can reconfigure the first time window again before the first signal is deactivated. The terminal device can then perform the first measurement within this reconfigured first time window (e.g., according to a new OD-SSB cycle or a new SMTC cycle). This eliminates the need to trigger the first time window through the deactivation and reactivation of the first signal, saving signaling overhead and improving the efficiency of the first measurement. As mentioned above, the first measurement can be a SCell measurement. Therefore, the first measurement configured based on the fifth configuration message mentioned here can be called an SCell measurement based on SSB adaptation or an SCell measurement based on SMTC adaptation. It should be understood that the SSB adaptation scheme mentioned in the embodiments of this application can be applied to Layer 1 measurements or Layer 3 measurements. Similarly, the SMTC adaptation mentioned in the embodiments of this application can be applied to Layer 1 measurements or Layer 3 measurements.

[0124] The first time window (hereinafter referred to as time window 2) configured (or reconfigured) based on the fifth configuration message can have the same length or different lengths as the first time window (hereinafter referred to as time window 1) determined based on the first configuration message. The measurement time requirements that the terminal device needs to meet when performing the first measurement in time window 1 can be the same as or different from the measurement time requirements it needs to meet when performing the first measurement in time window 2. For example, the terminal device needs to meet new time measurement requirements when performing the first measurement in time window 2. These new time measurement requirements can be determined based on M new OD-SSB or SMTC cycles, Q milliseconds (Q is a positive integer greater than or equal to 1), and the length of the first time window configured by the network device. For example, the new time measurement requirements can be the maximum value among M new OD-SSB or SMTC cycles, Q milliseconds, and the length of the first time window configured by the network device.

[0125] Furthermore, in some implementations, the starting position of the first time window configured in the fifth configuration message mentioned above is associated with the starting position of the period of the first time window. For example, the starting position of the first time window configured in the fifth configuration message can be the time domain position corresponding to the first time window position determined by the first configuration message plus an integer multiple (one or more) of the period of the first time window.

[0126] To facilitate understanding, Figure 14 is used as an example to illustrate the adaptation scheme mentioned above. Referring to Figure 14, after the network device sends the OD-SSB activation command to the terminal device, it begins OD-SSB transmission. After receiving the OD-SSB activation command, the terminal device also begins performing fast measurements within the fast window. After the fast window ends, the terminal device enters the slow window and begins slow measurements. The time range indicated by the dashed box in Figure 14 is the first time interval mentioned earlier, which represents the expected time interval between the OD-SSB activation command and the SCell activation command. As can be seen from Figure 14, the terminal device does not receive the SCell activation command within the first expected time interval. In this case, even if the OD-SSB is not deactivated, the terminal device stops measuring. When the next fast window, defined by the fast window period, arrives, since the OD-SSB is still not deactivated, the network device can send an OD-SSB configuration command to the terminal device (corresponding to the fifth configuration message mentioned earlier). This OD-SSB configuration command can be used to reconfigure the fast window, thereby fully utilizing the OD-SSB for fast measurements before it is deactivated. Furthermore, Figure 14 illustrates two ways to define the expected time interval between the OD-SSB activation command and the SCell activation command, namely time interval X and time interval Y in Figure 14. The difference between these two definitions lies in the starting position of the expected time interval. The starting position of time interval X is the OD-SSB activation (or reactivation) command, while the starting position of time interval Y is the starting position of the fast window. As for the length of the expected time interval, it can be defined using a predefined threshold or a timer.

[0127] Some embodiments described above define the period of a first time window (such as a fast measurement window). In some implementations, the interval between two adjacent first time windows can also be defined directly. The interval between two adjacent first time windows can be determined based on predefined protocol information. The interval between two adjacent first time windows can follow SCell's definition of an effective time window; for example, it can be defined as max(5s, 5*DRX periods), which is the maximum value among 5s and 5 DRX periods.

[0128] The embodiments of this application are described in more detail below with specific examples. It should be noted that the examples below are merely to help those skilled in the art understand the embodiments of this application, and are not intended to limit the embodiments of this application to the specific numerical values ​​or scenarios illustrated. Those skilled in the art can obviously make various equivalent modifications or variations based on the given examples, and such modifications or variations also fall within the scope of the embodiments of this application.

[0129] This example is used in at least the following four cases:

[0130] First: Scell ​​measurement based on multiple activations or deactivations of OD-SSB

[0131] Second: Measurement based on OD-SSB activation, reconfiguration, and deactivation

[0132] Third: Scell ​​measurement based on SSB adaptation

[0133] Fourth: Scell ​​measurement based on SMTC adaptation

[0134] This example can be followed as follows.

[0135] Step 1: The network device configures the frequency, period, and length of the OD-SSB via RRC. RRC also configures the length and / or period and / or time offset of the time window used for fast-mode measurements after each OD-SSB activation. RRC also configures the measurement threshold and / or timer. The threshold or timer can optionally be configured via RRC messages or predefined by the protocol.

[0136] Step 2: The network device issues a MAC CE, which contains an OD-SSB activation instruction.

[0137] Step 3: The terminal device performs fast-mode measurements based on the OD-SSB cycle. The measurement latency of the terminal device in fast mode must meet the longest of the following: N OD-SSB cycles and / or 200ms and / or the fast measurement window length requirement of the network configuration.

[0138] Step 4: After the fast measurement window, the terminal device enters the slow measurement and performs measurements according to the meascyclescell configured in the network.

[0139] a) One scenario is that the terminal device allows measurement to begin or stop only after receiving an OD-SSB deactivation command (optionally a MAC CE), reaching the time interval defined by the threshold, or the timer expires. In this case, the terminal device does not need to meet the SCell's measurement delay requirements. See Figure 13 for a detailed implementation.

[0140] (b) Another option is to use OD-SSB adaptation or SMTC adaptation. For example, referring to Figure 14, the network device sends an OD-SSB reconfiguration command (which can be a MAC CE or RRC reconfiguration message) to the terminal device. After receiving the OD-SSB reconfiguration command, the terminal device can perform measurements according to the new OD-SSB cycle or the new SMTC cycle. The new measurement time requirement must satisfy the longest of M new OD-SSB or SMTC cycles, and / or X ms, and / or the longest of the fast measurement window length requirements of the network configuration.

[0141] It should be understood that the threshold mentioned above can be defined as the duration of a pre-configuration after each OD-SSB activation or reconfiguration. Alternatively, the timer mentioned above can be defined as a timer that starts after each OD-SSB activation or reconfiguration. Following this definition, the time interval X in Figure 14 can be defined.

[0142] Alternatively, the threshold mentioned earlier can be a pre-configured duration after each fast measurement window starts. Or, the timer mentioned earlier can be defined as a timer that starts each time a fast measurement window arrives. Following this definition, the time interval Y in Figure 14 can be defined.

[0143] The method embodiments of this application have been described in detail above with reference to Figures 1 to 14. The apparatus embodiments of this application will be described in detail below with reference to Figures 15 to 17. It should be understood that the descriptions of the method embodiments correspond to the descriptions of the apparatus embodiments; therefore, any parts not described in detail can be referred to the preceding method embodiments.

[0144] Figure 15 is a schematic diagram of the structure of a communication device provided in an embodiment of this application. The communication device 1500 shown in Figure 15 can be the terminal device mentioned above. The communication device 1500 may include a communication unit 1510. The communication unit 1510 is used to receive a first configuration message sent by a network device, the first configuration message being used to trigger or activate a first signal, the first signal being used by the terminal device to perform a first measurement.

[0145] In some implementations, the communication unit 1510 is further configured to: receive a second configuration message sent by the network device, the second configuration message being configured to configure one or more of the following: the length of a first time window; the period of the first time window; time-domain location information of one or more first time windows; wherein the first time window is used to perform the first measurement.

[0146] In some implementations, the temporal location information of the one or more first time windows indicates one or more of the following: the temporal start position of the one or more first time windows; the temporal end position of the one or more first time windows; and the time offset associated with the temporal start position of the one or more first time windows.

[0147] In some implementations, the one or more first time windows include a second first time window within the period of the first time window, the time-domain start position of the second first time window being determined based on one or more of the following: the time-domain start position of the first first time window within the period of the first time window; the period of the first time window; and the time offset.

[0148] In some implementations, the time-domain starting position of the second first time window is the first time-domain position; or, the time-domain starting position of the second first time window is determined based on the first time-domain position and the time offset; wherein, the first time-domain position is the time-domain position obtained by adding the period of the first time window from the time-domain starting position of the first first time window.

[0149] In some implementations, the second configuration message is an RRC message.

[0150] In some implementations, the communication unit 1510 is further configured to: receive a third configuration message sent by the network device, the third configuration message being configured to configure one or more of the following: the time domain position of the first signal; the frequency domain position of the first signal; the spatial domain position of the first signal; and measurement time information for the second measurement.

[0151] In some implementations, the third configuration message is an RRC message.

[0152] In some implementations, the first configuration message is MAC CE or DCI.

[0153] In some implementations, the communication unit 1510 is further configured to: receive the first signal according to the third configuration message after the first configuration message triggers or activates the first signal.

[0154] In some implementations, the communication unit 1510 is further configured to: receive a fourth configuration message sent by the network device, the fourth configuration message being used to deactivate the first signal.
