[0053] Before the embodiments of the present application are described, the related art will be briefly introduced as follows:

[0054] 1. On-demand SSB

[0055] A new network energy saving technology is proposed in the related art. The network side device can send SSB on demand, that is, on-demand synchronized signal block (OD-SSB). Before the introduction of OD-SSB, the network side device sends SSB according to the pre-configured period for UE to perform cell search and synchronization. After the introduction of OD-SSB, the network side device can not continuously send SSB on some cells and frequency points, that is, in the case that there is no UE accessing the frequency point, the SSB is completely stopped, and is sent again when there is a real demand.

[0056] For example, for the inter-frequency deployment scenario shown in FIG. 2, the network side device can perform SSB transmission on the first frequency point f1 according to the traditional behavior, according to the pre-configured period, for UE to perform cell search and synchronization. When the number of users in the cell is large, only based on the carrier corresponding to f1 to perform coverage cannot meet the multi-user communication demand, causing communication congestion, the network side device can consider further activating the carrier corresponding to the second frequency point f2. At this time, OD-SSB can be transmitted on f2. When the number of users decreases, the network can stop transmitting OD-SSB. Since SSB no longer needs to be transmitted according to the period, in the time when OD-SSB is not transmitted, the network can completely close the carrier corresponding to f2 and the related radio frequency devices, achieving the purpose of network energy saving.

[0057] For example, for the inter-frequency deployment scenario shown in FIG. 2, another method to achieve network energy saving is that, assuming that on the carrier corresponding to the third frequency point f3, the network side device transmits ordinary SSB according to a longer period, for example, with a period of 160 ms. When the number of users in the cell increases, the network needs to speed up the process of measurement and secondary cell activation process of each UE user in the cell corresponding to f3, so as to achieve fast radio resource management and improve network efficiency. In this case, the network can transmit a SSB with a denser period on the second frequency point f2, that is, OD-SSB. When the number of users on the cell is small, the SSB with a denser period on f2 can be closed, so as to achieve the purpose of network energy saving.

[0058] 2. In general carrier aggregation technology, deactivation of secondary cell measurement

[0059] The UE itself also has energy saving needs. In the related art, in the UE measurement behavior and measurement index definition of 5G NR, for an inactive secondary cell, the network side device additionally configures a measurement cycle (MeasCycleSCell) of the deactivated secondary cell for the UE, and the UE can perform measurement on the deactivated SCell according to the cycle without performing measurement according to the SSB cycle. The measurement cycle of the deactivated secondary cell is configured under the measurement object configuration of layer 3 (L3) measurement, and takes effect only when the object corresponds to the frequency layer of the secondary cell SSB. The minimum value of the measurement cycle of the deactivated secondary cell is 160sf, that is, 160ms, which is much larger than the general SSB cycle, that is, 20ms. According to the protocol definition, at this time, the L3 measurement of the deactivated secondary cell belongs to the intra-frequency measurement, and no gap is required. In other words, although the UE has the radio frequency capability necessary for carrier aggregation, that is, the interruption of uplink and downlink transmission of the serving cell when measuring the frequency point corresponding to the secondary cell can be greatly reduced (even to 0 in some scenarios), but the UE activates the radio frequency link and baseband reception corresponding to the secondary cell, which still brings additional power consumption. From the perspective of UE energy efficiency, performing L3 measurement similar to measurement behavior in discontinuous reception (DRX) on the secondary cell can greatly reduce the UE power consumption overhead.

[0060] From the perspective of network energy saving, the network side device sends SSB on demand. The design of MeasCycleSCell is based on the assumption that the network side device is always sending SSB, and the UE only needs to measure a subset containing a part of the SSB. From the respective energy saving perspectives, there is a certain conflict in the design ideas. Therefore, a new measurement scheme needs to be proposed to ensure network energy saving, UE energy saving, and fast activation of the secondary cell.

[0061] 3. Cell search module in the UE

[0062] In the general UE implementation of 5G NR, a dedicated cell search module (that is, Searcher) is implemented to search for a cell synchronization signal. Before cell search, the time and frequency synchronization information of the cell may be completely missing. The network side device can give some basic synchronization information through some configuration signaling, such as the approximate position of the SS / PBCH block measurement timing configuration (SMTC) and the approximate position of the SSB corresponding to a certain sequence number, etc., but the actual reception timing of each SSB needs to be obtained through the cell search module.

[0063] Therefore, the cell search module is generally based on multiple fast Fourier transform (FFT) windows. Through multiple searches in the time domain and the frequency domain, optimal time-frequency domain synchronization is obtained. Even for the serving cell, it is possible to lose synchronization due to a too low signal to noise ratio (SNR). Once synchronization is lost, the way to recover synchronization generally needs to rely on cell search and measurement with multiple FFT windows.

[0064] For a multi-frequency deployment scenario, the network side device generally configures the UE with serving cell measurement. For carrier aggregation, different types of serving cells also have differences in the use of the cell search module. According to the definition of the UE measurement index in the current 5G NR, it is generally assumed that the UE is equipped with 2 Searchers. For the primary cell center (PCC) frequency point corresponding to the primary cell (PCell), it is generally assumed that a Searcher is separately occupied, and for the serving cell measurement of the primary secondary cell (PSCell) and the secondary cell (SCell), another Searcher is generally shared.

[0065] In view of this, the embodiments of the present application provide a measurement method, a measurement configuration method, an apparatus and a communication device to solve the problem of how the terminal performs measurement in the case that the secondary cell is not activated.

[0066] The measurement method and the measurement configuration method provided by the embodiments of the present application will be described in detail in combination with the drawings, some embodiments and application scenarios.

[0067] FIG. 3 shows a flowchart of a measurement method provided by an embodiment of the present application. As shown in FIG. 3, the measurement method comprises the following steps:

[0068] Step 301: In the case that a target secondary cell is not activated, a terminal determines a first time length;

[0069] Step 302: The terminal performs measurement of SSB according to a first period within the first time length;

[0070] Step 303: In the case that the first time length is exceeded and the target secondary cell transmits SSB, the terminal performs measurement of the target secondary cell according to a second period;

[0071] The first period is N times of the period of the SSB, the time length of the second period is greater than the time length of the first period, and N is greater than or equal to 1.

[0072] The time length of the first period can be understood as a minimum interval for the UE to perform measurement. When N is equal to 1, the time length of the first period is an interval between two adjacent SSBs sent by the network side device; when N is greater than 1, the time length of the first period is greater than an interval between two adjacent SSBs sent by the network side device. N can be an integer or a non-integer, and embodiments of the present application do not limit this. In particular, when N is a non-integer, an even multiple of N can be an integer, for example, N can be 1.5 or 2.5, etc.

[0073] The time length of the second period can be understood as an interval between two adjacent secondary cell measurements performed by the UE for an inactivated secondary cell. The interval is generally greater than an interval between two adjacent SSBs. The interval is generally determined based on RRC configuration issued by the network side device.

[0074] The time length of the second period is greater than the time length of the first period, which can be understood as that when the first period is used to perform measurement, the terminal performs secondary cell SSB measurement at a denser period, and when the second period is used to perform measurement, the terminal performs secondary cell SSB measurement at a sparser period.

[0075] The measurement of the SSB performed by the terminal within the first time length can include L3 measurement and / or L1 measurement. The measurement of the target secondary cell performed by the terminal beyond the first time length can include L3 measurement and / or L1 measurement.

[0076] Here, the L1 measurement generally refers to SSB measurement configured under channel state information (CSI) measurement configuration. The UE reports the measurement result through a physical uplink control channel (PUCCH).

[0077] Here, the L3 measurement generally refers to SSB or SMTC-based measurement configured under L3 measurement object configuration. The main purpose of the measurement here is to obtain L3 reference signal received power (L3-RSRP). The measurement result generally undergoes a filtering process configured by L3, and compared with L1 measurement, generally needs to detect the reference signal (such as a neighbor cell) of the corresponding cell at a lower signal-to-noise ratio.

[0078] In the embodiments of the present application, when the target secondary cell is not activated, the terminal determines a first time length; the terminal performs measurement of the SSB according to a first period within the first time length; when the first time length is exceeded and the target secondary cell transmits the SSB, the terminal performs measurement of the target secondary cell according to a second period; wherein the first period is N times of the period of the SSB, the time length of the second period is greater than the time length of the first period, and N is greater than or equal to 1. In this way, by performing measurement of the SSB with a smaller period (i.e. the first period) within the first time length, the terminal can achieve efficient measurement of the SSB, and by performing measurement of the secondary cell with a larger period (i.e. the second period) when the first time length is exceeded, the energy consumption of the terminal can be reduced. Therefore, the embodiments of the present application can not only guarantee network energy saving, but also guarantee UE energy saving. Moreover, since efficient measurement of the SSB can be achieved, the rapid activation of the secondary cell can also be guaranteed.

[0079] In some embodiments, the SSB is an on-demand SSB (OD-SSB).

[0080] It should be noted that the SSB can also be a synchronization signal block without a physical broadcast channel (PBCH) in 6G, or any other type of synchronization signal block, such as a non-on-demand synchronization signal block in 5G.

[0081] In some embodiments, in the first period, N = 1 or 1.5.

[0082] Or,

[0083] The second period is a secondary cell measurement period pre-configured by the network side device.

[0084] For example, the second period is the period of MeasCycleSCell pre-configured by the network side device, i.e. the UE directly determines based on the RRC configuration issued by the network.

[0085] In the embodiments of the present application, the length of the first time length can be pre-defined by a protocol or determined based on network configuration.

[0086] The first time length can be a protocol-defined determined value, which is independent of RRC configuration. Alternatively, the first time length is a value derived based on other configurations and / or UE states according to a protocol pre-defined rule.

[0087] Taking OD-SSB as an example, assuming that the configuration of the OD-SSB is within the current active bandwidth part (BWP) of the UE, the value of the first duration is 6400ms. If the OD-SSB is outside the current active BWP of the UE, the value of the first duration is 1600ms.

[0088] For example, assuming the SSB period of the OD-SSB configuration is 40ms, then the first duration includes at least N SSB periods, i.e., 40*N ms. N is a fixed value defined by the protocol.

[0089] The first duration can also be a value directly determined based on network configuration.

[0090] In some embodiments, the starting point of the first duration is the time when the SSB is activated. For example, the starting point of the first duration is the time when the UE receives the activation signaling of the SSB.

[0091] In some embodiments, the SSB is activated in at least one of the following ways:

[0092] The terminal receives a Radio Resource Control (RRC) message, which contains the activation signaling of the SSB;

[0093] The terminal receives an RRC reconfiguration message, which contains the configuration information of the measurement object (MO) where the SSB is located;

[0094] The terminal receives a Medium Access Control Element (MAC CE), which contains the activation signaling of the SSB;

[0095] The terminal receives Downlink Control Information (DCI), which includes the activation signaling of the SSB.

[0096] Taking OD-SSB as an example, the network-side device indicates to the UE via MAC CE or DCI that it has enabled OD-SSB transmission. After receiving the MAC CE or DCI, the UE enables OD-SSB reception. Here, OD-SSB reception may be used for synchronization or L1 / L3 measurements.

[0097] Here, the MAC CE or DCI belongs to downlink indication. In some embodiments, the activation signaling of the SSB corresponds to downlink scheduling based on group common DCI. That is, the downlink transmission carrying the indication is scheduled based on group common DCI.

[0098] In this way, the cell can activate all connected state UEs supporting and configured with the corresponding feature to perform OD-SSB measurement through one activation signaling. It should be noted that the synchronization here is also commonly referred to as a cell search process or a cell discovery process. The UE acquires coarse synchronization of all available cells by attempting multiple time-frequency synchronization windows to receive primary synchronization signals (PSS) and secondary synchronization signals (SSS).

[0099] In some embodiments, the terminal determines a first time length, including at least one of the following:

[0100] The terminal determines the transmission time length of the SSB as the first time length.

[0101] The terminal determines the timing time length corresponding to the first timer configured by the network side device as the first time length.

[0102] Taking OD-SSB as an example, the starting condition of the first timer can be that the UE receives DCI or MAC CE signaling indicating that the UE can start receiving OD-SSB. Before the first timer expires, the UE performs measurement according to the period of OD-SSB.

[0103] In some embodiments, in the case where the configuration information of the measurement target in which the SSB is located is included in the RRC reconfiguration message, the reporting event associated with the measurement target in which the SSB is located does not include an A6 event, or the measurement configuration of the measurement target in which the SSB is located includes configuration of the SSB period and does not include SMTC.

[0104] Taking OD-SSB as an example, the network side device can configure the resources of OD-SSB in RRC. These configuration signals do not directly indicate that the network side device has started transmitting OD-SSB. However, from the perspective of the UE, the UE can start reserving cell search resources for OD-SSB at the moment when the RRC configuration is received and the RRC signaling decoding is completed. The cell search resource can be understood as a certain time window in which the cell search module occupies the frequency layer corresponding to the OD-SSB to perform measurement.

[0105] In an implementation, the OD-SSB resource is configured by L3 measurement configuration, configured in L3 measurement object. Based on such configuration, the UE performs L3 measurement after receiving the activation signaling of the OD-SSB. In this way, considering that the OD-SSB is a SSB signal issued by a certain cell based on current service requirement, it is difficult to compare the serving cell and the neighbor cell in the frequency layer where the OD-SSB is issued. Therefore, the measurement object cannot contain A6 event, i.e. comparison between the secondary serving cell and the corresponding same-frequency neighbor cell, so that the invalid overhead caused by UE performing neighbor cell search can be effectively avoided in the state where the network has flexible requirement.

[0106] Based on the same consideration, the measurement object does not contain the configuration of SMTC (i.e. synchronization measurement time window). Here, the synchronization measurement time window configuration refers to the time window configured by the network side device for L3 cell search, in each time window, all cells corresponding to the SSB frequency point issue SSB for UE to perform cell search. Since it cannot be guaranteed that all cells issue SSB in the frequency point corresponding to the OD-SSB, in the L3 measurement object configuration, only the SSB period of the corresponding cell needs to be configured.

[0107] In some embodiments, the terminal performs measurement of the target secondary cell in the first time period according to a first period, including:

[0108] In the case where the first time period is less than a first threshold, the terminal performs measurement of the target secondary cell in the first time period according to the first period;

[0109] The method further includes:

[0110] In the case where the first time period is greater than or equal to the first threshold, the terminal performs measurement of the target secondary cell in the first time period according to the second period.

[0111] For example, if the terminal determines that the first time period is less than the first threshold, the terminal performs measurement in the first time period according to the period of the OD-SSB; if the first time period is greater than or equal to the first threshold, the terminal performs measurement in the first time period according to the MeasCycleSCell period.

[0112] The specific value of the first threshold can be determined according to the time for the UE to complete cell search and cell measurement under a certain signal-to-noise ratio condition using MeasCycleSCell as the measurement period. The typical condition of the signal-to-noise ratio is -3dB or -6dB.

[0113] That is, in the case that the first duration is greater than or equal to the first threshold, the first duration is large enough, i.e., the SSB measurement time configured by the network device for the terminal is enough, and then the terminal can perform SSB measurement in a more sparse period, which can further reduce the SSB measurement energy consumption of the terminal.

[0114] In some embodiments, the method further includes:

[0115] The terminal stops timing of the first duration in the case that the MAC CE or the DCI used to indicate that the SSB is to be deactivated is received.

[0116] That is, if the network device directly issues the MAC CE or the DCI signaling to inform the UE that the OD-SSB is deactivated, it means that the network device no longer sends the OD-SSB, and the timing of the first duration is also stopped accordingly.

[0117] When the first duration expires, if the network device does not deactivate the OD-SSB through the MAC CE or the DCI or the RRC signaling, the UE can no longer use the OD-SSB period to measure the target secondary cell, but use the measurement period of MeasCycleSCell (i.e., the second period) to measure the target secondary cell. In this way, the UE will not use the OD-SSB period to measure the secondary cell for an unlimited time. When the UE falls back to the measurement period of MeasCycleSCell, the network device can choose to deactivate the OD-SSB to achieve network energy saving. Of course, if there is indeed a UE that successfully accesses the secondary cell, the network device can also choose not to deactivate the OD-SSB, but for the UE that has not successfully accessed, a more relaxed measurement behavior can be used to achieve the purpose of saving UE power consumption.

[0118] In some embodiments, the method further includes:

[0119] The terminal determines a second duration;

[0120] In the second duration, the terminal does not need to activate the first duration based on the activation signaling of the SSB.

[0121] Here, for the network device to configure the first duration by configuring the first timer, activating the first duration can be understood as starting the timing of the first timer.

[0122] In this implementation, the UE starts the timing of the first duration and also starts the timing of the second duration.

[0123] If the UE receives new SSB activation signaling (such as MAC CE or DCI signaling) after the first time length, if the second time length is still being counted, the UE still performs the measurement of the OD-SSB according to the MeasCycleSCell; if the second time length has stopped counting, the UE can perform the measurement of the OD-SSB according to the OD-SSB period.

[0124] Through the implementation, the network side device can be effectively prevented from frequently issuing MAC CE or DCI to trigger the UE to restart the encryption measurement based on the OD-SSB, so as to ensure the energy saving of the terminal.

[0125] In some embodiments, the starting point of counting of the second time length is the time point at which the SSB is activated.

[0126] In some embodiments, the terminal determines the second time length, including:

[0127] The terminal determines the counting time length corresponding to the second timer configured by the network side device as the second time length.

[0128] The second time length is determined based on the configuration of the network side device. Specifically, the network side device configures a second timer, and before the second timer expires, the UE does not need to activate the first time length based on the OD-SSB activation signaling, that is, before the second timer expires, the UE does not need to start the first timer based on the OD-SSB activation signaling.

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

[0130] The terminal, within a third time length after reporting the measurement result of the SSB, if receiving the activation signaling of the target secondary cell, performs the activation of the target secondary cell according to the activation condition of the target secondary cell in the known state.

[0131] The activation condition may, for example, be a protocol-defined maximum activation time length of the UE, that is, the UE needs to complete the activation of the target secondary cell within the maximum activation time length. The starting point of the activation time length is the time at which the UE receives the secondary cell activation signaling.

[0132] In this implementation, assuming that the reporting of the SSB measurement result occurs before the issuance of the target secondary cell activation signaling, if the interval between the issuance time of the target secondary cell activation signaling and the completion time of the measurement reporting is less than the third time length, regardless of whether there is the transmission of the OD-SSB within the third time length, the UE considers the target secondary cell to be a known secondary cell, that is, the activation time length of the target secondary cell adopts the activation time length in the known state (or known condition) of the target secondary cell.

[0133] In some embodiments, the method further includes:

[0134] If the target secondary cell is configured with both layer 3 measurement reporting and layer 1 measurement reporting, the terminal reports the measurement result of the SSB on a physical uplink shared channel (PUSCH) corresponding to layer 3 measurement reporting after obtaining the measurement result of the SSB, and reports the measurement result of the SSB on a PUCCH corresponding to layer 1 measurement reporting.

[0135] As an implementation manner, assuming that the measurement can be reported on both L1 and L3, the UE reports on the resource of the first arrival of the PUSCH and the PUCCH on the primary cell. Specifically, assuming that the PUSCH is scheduled first, and the UE does not have a periodic PUCCH resource available when the PUSCH is scheduled, the UE reports on the PUSCH. Assuming that the PUCCH resource has arrived before the PUSCH is scheduled, the UE reports on the PUCCH.

[0136] As another implementation manner, assuming that the measurement can be reported on both L1 and L3, the UE reports on both the PUSCH and the PUCCH on the primary cell. In this case, assuming that the measurement and / or reporting occurs after the target secondary cell activation signaling is issued, there are two ways to calculate the target secondary cell activation time, which are described as follows.

[0137] In some embodiments, the method further includes:

[0138] If the measurement result of the SSB is reported during the activation process of the target secondary cell, and the terminal completes the layer 1 measurement reporting and the reception of the target signaling before the layer 3 measurement reporting, the terminal counts a fourth time length into the activation time length of the target secondary cell, and does not count a fifth time length into the activation time length of the target secondary cell.

[0139] Alternatively,

[0140] If the measurement result of the SSB is reported during the activation process of the target secondary cell, the terminal counts both the fifth time length and a sixth time length into the activation time length of the target secondary cell.

[0141] The fourth time length is a time length for waiting for layer 3 measurement reporting, the fifth time length is a time length for waiting for reception of the target signaling, and the sixth time length is a time length corresponding to the earlier one of the layer 3 measurement reporting and the layer 1 measurement reporting.

[0142] The target signaling includes at least one of the following:

[0143] Signaling for activating transmission configuration indicator (TCI) sent by a network-side device;

[0144] Signaling for configuring periodic channel state information (CSI) measurement sent by a network-side device;

[0145] Signaling for activating semi-static CSI measurement sent by a network-side device.

[0146] The CSI measurement described above is mainly channel quality indicator (CQI) measurement.

[0147] It should be noted that, for the mode before "or", if the corresponding target signaling is received after layer 3 reporting, the duration for which the corresponding terminal waits for the target signaling described above still needs to be included in the activation duration of the target secondary cell.

[0148] For the mode after "or", the duration for which the UE waits for the target signaling described above (i.e., the fifth duration) is included in the SCell activation duration, and the starting point is the earlier one of the time of L3 reporting and the time of L1 reporting.

[0149] The above is a method embodiment on the terminal side, and a method embodiment on the network-side device is described below.

[0150] FIG. 4 shows a flowchart of a measurement configuration method provided by an embodiment of the present application. As shown in FIG. 4, the measurement configuration method includes the following steps:

[0151] Step 401: A network-side device configures a first timer for a terminal, and the timing duration of the first timer is a first duration;

[0152] Wherein, within the first duration, measurement of a synchronization signal block (SSB) is performed at a first period; when the first duration is exceeded and the target secondary cell sends an SSB, measurement of the target secondary cell is performed at a second period;

[0153] The first period is N times of the period of the SSB, the time length of the second period is greater than the time length of the first period, and N is greater than or equal to 1.

[0154] In some embodiments, step 401 includes:

[0155] The network-side device configures a first timer for the terminal when it is necessary to activate a target secondary cell.

[0156] The network-side device can configure the first timer before activating the target secondary cell (i.e., before issuing the target secondary cell activation signaling), or can configure the first timer when activating the target secondary cell (i.e., when issuing the target secondary cell activation signaling), for example, carrying the configuration information of the first timer in the target secondary cell activation signaling. That is, the network-side device configures the first timer for the terminal no later than the time when the network-side device activates the target secondary cell.

[0157] In some embodiments, the SSB is an on-demand issued synchronization signal block (OD-SSB).

[0158] In some embodiments, in the first period, N = 1 or 1.5.

[0159] Or,

[0160] The second period is a secondary cell measurement period pre-configured by the network-side device.

[0161] In some embodiments, the starting point of the first timer is the time point when the SSB is activated.

[0162] In some embodiments, the method further comprises:

[0163] The network-side device configures a second timer for the terminal, and the timing duration of the second timer is a second duration.

[0164] In the second duration, the first timer does not need to be activated based on the activation signaling of the SSB.

[0165] In some embodiments, the starting point of the second timer is the time point when the SSB is activated.

[0166] The related description of the embodiments of the present application can be referred to the related description of the method embodiments of FIG. 3, and the same technical effects can be achieved. To avoid repetition, this will not be described here.

[0167] The following provides a plurality of specific embodiments to exemplarily illustrate the schemes of the embodiments of the present application.

[0168] Embodiment 1

[0169] As shown in FIG. 5a, the following steps are included:

[0170] Step 1: The network-side device configures the resources of the OD-SSB in RRC. These configuration signals do not directly indicate that the network-side device has started to send the OD-SSB. But from the perspective of the UE, the UE can start to reserve the cell search resources for the OD-SSB at the time when the RRC configuration is received and the RRC signaling decoding is completed.

[0171] The configuration of the OD-SSB resource includes two specific implementations:

[0172] The first implementation is through L3 measurement configuration, which is configured in the L3 measurement object. Based on such configuration, the UE performs L3 measurement after receiving the activation signaling of the OD-SSB. In this implementation, considering that the OD-SSB is a SSB signal issued by a cell based on current service requirements, it is difficult to compare the serving cell and the neighboring cell at the frequency layer where the OD-SSB is issued. Therefore, the measurement object cannot include A6 events, i.e., the comparison between the secondary serving cell and the corresponding same-frequency neighboring cell, so as to effectively avoid the invalid overhead caused by the UE performing neighboring cell search in the state where the network has flexible requirements.

[0173] In addition, optionally, based on the same consideration, there is no SMTC, i.e., synchronization measurement time window configuration, in the measurement object. The synchronization measurement time window configuration refers to a time window configured by a network device for L3 cell search, in which all cells corresponding to the SSB frequency point issue SSBs for UE cell search. Since all cells cannot be guaranteed to issue SSBs on the frequency point corresponding to the OD-SSB, only the SSB period of the corresponding cell needs to be configured in the L3 measurement object configuration.

[0174] The second implementation is through L1 measurement configuration, which is configured in the CSI measurement reporting configuration. At this time, the network device needs to configure the L1 reporting of the corresponding secondary cell. The uplink transmission carrying the L1 reporting is completed in the primary cell (PCell) or the primary secondary cell (PSCell).

[0175] Step 2: The network device indicates that the network device has started transmitting the OD-SSB through MAC CE or DCI. After completing the reception of the MAC CE or DCI, the UE starts receiving the OD-SSB. Here, the reception of the OD-SSB can be used for synchronization or L1 / L3 measurement.

[0176] Here, the MAC CE or DCI indication is a downlink indication. In particular, the downlink transmission carrying the indication is scheduled based on group common DCI. In this way, the cell can activate all connected state UEs that support and are configured with the corresponding characteristics through one activation signaling to perform OD-SSB measurement.

[0177] It should be noted that synchronization, also commonly referred to as cell search process or cell discovery process, is a process in which the UE attempts to receive the primary synchronization signal (PSS) and the secondary synchronization signal (SSS) in multiple time-frequency synchronization windows to obtain coarse synchronization of all available cells.

[0178] Here, L1 measurement generally refers to SSB measurement under the configuration of CSI measurement configuration. UE reports the measurement result on PUCCH.

[0179] Here, L3 measurement generally refers to SSB or SMTC based measurement under the configuration of L3 measurement object configuration. The main purpose of the measurement here is to obtain L3-RSRP. The measurement result generally undergoes filtering process configured by L3, and compared with L1 measurement, the corresponding cell reference signal (such as neighbor cell) needs to be detected at a lower signal-to-noise ratio.

[0180] Step 3: UE performs the above measurement, including cell search, L1 measurement or L3 measurement, in the first time length based on the period of OD-SSB.

[0181] In particular, the first time length can be a protocol defined fixed value, which is irrelevant to RRC configuration.

[0182] In particular, the first time length can also be a value derived based on other configurations and / or UE state according to a protocol predefined rule.

[0183] For example, assuming that the configuration of OD-SSB is in the current active BWP of UE, the value of the first time length is 6400 ms, and assuming that the OD-SSB is outside the current active BWP of UE, the value of the first time length is 1600 ms.

[0184] For example, assuming that the SSB period of the configuration of OD-SSB is 40 ms, the first time length includes at least N SSB periods, i.e. 40*N ms. The N is a protocol defined fixed value.

[0185] In particular, the first time length can also be a value directly determined based on network side device configuration, i.e. the network side device configures a first timer, and the starting condition of the first timer is that UE receives DCI or MAC CE signaling indicating that UE can start receiving OD-SSB. Before the first timer expires, UE performs measurement according to the period of OD-SSB. In particular, the configuration of the first timer can be given in RRC signaling for configuring OD-SSB measurement, or can be directly carried by activation signaling of OD-SSB.

[0186] In particular, in the present scheme, the confirmation method of the end point of the first time length further includes:

[0187] If UE receives MAC CE or DCI signaling indicating that the OD-SSB of UE will be deactivated, UE stops the timing of the first time length or stops the first timer.

[0188] That is, if the network side device directly issues a MAC CE or DCI signaling to inform the UE that the OD-SSB is deactivated, and the network side device no longer sends the OD-SSB, the timing of the first duration also stops accordingly.

[0189] Step 4: When the first duration expires, and the network side device does not deactivate the OD-SSB through a MAC CE or DCI or RRC signaling, the UE no longer uses the OD-SSB period to measure the secondary cell, but uses the MeasCycleSCell to measure the secondary cell.

[0190] Based on the above Step 3 and Step 4 design, the UE will not use the OD-SSB period to measure the secondary cell for an infinite time. In this way, when the UE falls back to MeasCycleSCell, the network side device can choose to deactivate the OD-SSB to achieve network energy saving. Of course, if there is indeed a UE that successfully accesses the secondary cell, the network side device can also choose not to deactivate the OD-SSB, but for UEs that have not successfully accessed, a more relaxed measurement behavior can be used to achieve the purpose of saving UE power consumption.

[0191] Step 5: UE reports L1 or L3 measurement results. Here, further consider the timing relationship between SCell activation and OD-SSB measurement activation, including the following options:

[0192] Option A: OD-SSB measurement occurs before the UE receives the SCell activation signaling, and the reporting also occurs before the SCell activation, that is, it is the L1 / L3 measurement for deactivating the SCell. The network side device determines whether to activate the SCell according to the measurement results reported by the UE.

[0193] Option B: OD-SSB measurement occurs before the UE receives the SCell activation signaling, but reporting occurs after the SCell activation signaling, that is, reporting is triggered by the SCell activation signaling.

[0194] Option C: OD-SSB measurement occurs after the UE receives the SCell activation signaling, and reporting also occurs after the SCell activation signaling. That is, the SCell activation signaling directly triggers the measurement and reporting of the OD-SSB.

[0195] For the above three options, assuming that the UE obtains L1 and / or L3 measurement results in Step 3 or Step 4, the UE reports on the corresponding primary cell.

[0196] In particular, one optional implementation is that, assuming the measurement can be reported at L1 or L3, the UE reports on the resource of the first arrival between PUSCH and PUCCH on the primary cell. Specifically, assuming that PUSCH is scheduled first, and there is no periodic PUCCH resource available to the UE when PUSCH is scheduled, the UE reports L3 on PUSCH. Assuming that the PUCCH resource has arrived before PUSCH is scheduled, the UE reports L1 on PUCCH.

[0197] In particular, another optional implementation is that, assuming the measurement can be reported at L1 or L3, the UE reports on the resource of the first arrival between PUSCH and PUCCH on the primary cell. Specifically, assuming that the measurement and / or reporting occurs after the secondary cell activation signaling is issued, there are two implementation options for the calculation of the secondary cell activation duration:

[0198] Option 1: As shown in FIG. 5b, the secondary cell activation duration only includes the duration of L3 measurement reporting (i.e., the fourth duration), and assuming that the L1 reporting and TCI activation are completed before the L3 reporting, the UE waits for the duration of the following target signaling (i.e., the fifth duration), which is not included in the secondary cell activation duration: (including the corresponding item duration as 0)

[0199] the signaling for activating TCI issued by the network side device;

[0200] the signaling for configuring periodic channel state information (CSI) measurement issued by the network side device;

[0201] the signaling for activating semi-static CSI measurement issued by the network side device.

[0202] Obviously, if the corresponding target signaling is received after the L3 reporting, the duration of the UE waiting for the target signaling still needs to be included in the activation duration of the secondary cell.

[0203] Option 2: As shown in FIG. 5c, the secondary cell activation duration only includes the duration of the earlier one of L3 reporting and L1 reporting (i.e., the sixth duration), and the UE waits for the duration of the following target signaling (i.e., the fifth duration), which is included in the starting point of the SCell activation duration: (including the corresponding item duration as 0)

[0204] the signaling for activating TCI issued by the network side device;

[0205] the signaling for configuring periodic channel state information (CSI) measurement issued by the network side device;

[0206] the signaling for activating semi-static CSI measurement issued by the network side device.

[0207] Step 6: Assuming that the measurement reporting in Step 5 occurs before the auxiliary cell activation signaling is issued, if the interval between the auxiliary cell activation signaling issuance time and the measurement reporting completion time is less than a third time length, the UE considers the corresponding auxiliary cell to be a known auxiliary cell, regardless of whether there is OD-SSB transmission within the third time length, i.e., the auxiliary cell activation time length adopts the time length under the known auxiliary cell condition.

[0208] It should be noted that all the above-mentioned auxiliary cell activation time lengths are the maximum time lengths allowed by the protocol for the UE to perform. In actual operation, the actual auxiliary cell activation time length of the UE can be less than or equal to the time length, but cannot be longer than the time length. The specific time length is not limited by the present application.

[0209] Embodiment 2

[0210] As shown in FIG. 6, the following steps are included:

[0211] Steps 1 to 2: Same as Embodiment 1, which will not be repeated.

[0212] In the process of performing Step 3, the UE starts timing of a second time length in addition to timing of a first time length. All other details of Step 3 are the same as those of Embodiment 1 and will not be repeated.

[0213] The specific details of Step 4 are also the same as those of Embodiment 1. This embodiment focuses on the assumption that after Step 4, the UE receives a new MAC CE or DCI signaling. For this case, the UE needs to restart the timing of the first time length according to Embodiment 1. For Embodiment 2, Step 4A is entered:

[0214] Step 4A: Assuming that the UE finds that the second time length is still timing during the process of receiving the MAC CE or DCI, the UE still performs the measurement of the OD-SSB according to MeasCycleSCell. Assuming that the second time length has stopped timing during the process of receiving the MAC CE or DCI, Step 3 is performed.

[0215] Through such a design, it is possible to effectively avoid the network side device frequently issuing the MAC CE or DCI to trigger the UE to restart the encryption measurement based on the OD-SSB.

[0216] In addition, optionally, in Embodiment 2, the second MAC CE or DCI and the third MAC CE or DCI can also be encryption measurement indications issued through scheduling DCI, and are not limited to OD-SSB activation signaling.

[0217] In particular, the configuration of the second timer can be given in RRC signaling configured for OD-SSB measurement, or directly carried by activation signaling of OD-SSB.

[0218] In particular, in the embodiment, the method for confirming the end point of the second time length further comprises:

[0219] If the UE receives MAC CE or DCI signaling indicating that the OD-SSB of the UE is to be deactivated, the UE will not stop the timing of the second time length.

[0220] Embodiment 3

[0221] As shown in FIG. 7, the method comprises the following steps:

[0222] Steps 1 to 2: In the embodiment, the steps can be combined. After receiving the RRC signaling, the UE obtains the activation information of the OD-SSB after decoding the RRC signaling. The UE does not need to obtain any additional activation information of the OD-SSB through additional signaling. The network side device can activate the timing or re-timing of the first time length through MAC CE signaling or DCI. Whether the RRC signaling or the DCI or the MAC CE and the like underlying signaling is received, the timing of the first time length can be activated.

[0223] Similarly, in the embodiment, the deactivation of the OD-SSB can also be performed based on the RRC signaling, rather than being deactivated based on the DCI or the MAC CE. In the embodiment, the method for confirming the end point of the second time length further comprises:

[0224] If the UE receives RRC signaling indicating that the OD-SSB of the UE is to be deactivated, the UE will not stop the timing of the second time length.

[0225] The other steps of the embodiment are the same as those of Embodiment 2, and will not be described herein.

[0226] Embodiment 4

[0227] As shown in FIG. 8, most of the embodiment is the same as Embodiment 2, and the difference lies in that:

[0228] Step 2: The network side device indicates the network side device to start transmitting the OD-SSB through the MAC CE or the DCI. In the indication, the network side device indicates the transmission time of the OD-SSB of the UE, or the number of transmitted SSBs based on the RRC configuration or the dynamic indication of the MAC CE and the DCI.

[0229] Optionally, the UE can determine the transmission time as the first time length when determining the first time length. That is, the UE does not consider the OD-SSB to be in a transmitting state after the first time length and before receiving the next OD-SSB triggering signaling.

[0230] In particular, the measurement method for determining the OD-SSB further includes that if the length of the first time length is less than a first threshold, the UE performs measurement with a period of the OD-SSB. If the length of the first time length is greater than or equal to the first threshold, the UE performs measurement with the MeasCycleSCell.

[0231] For example, the specific value of the first threshold can be determined according to the time for the UE to complete the cell search and cell measurement under a certain signal-to-noise ratio condition using the MeasCycleSCell as the measurement period. The typical condition of the signal-to-noise ratio is -3 dB or -6 dB.

[0232] In summary, the embodiments of the present application can achieve efficient SSB-based measurement, which can reduce the energy consumption of the network and ensure that the UE energy consumption does not increase significantly due to network energy saving.

[0233] The embodiments of the present application can also be used for a synchronization signal block without PBCH in 6G or any other type of synchronization signal block, such as a non-on-demand synchronization signal block in 5G. When used for non-OD-SSB, the network side device can always transmit the SSB, but the measurement or reporting is based on MAC CE triggering. At this time, the embodiments of the present application are still applicable to options B and C.

[0234] The measurement method provided by the embodiments of the present application can be executed by a measurement device. In the embodiments of the present application, the measurement device is taken as an example to illustrate the measurement device provided by the embodiments of the present application.

As an example, the measurement device can be a communication device or a component in a communication device, such as a chip. The communication device can be a terminal, a network side device, a server, or the like. For example, the terminal can include but is not limited to the types of the terminal 11 listed above, the network side device can include but is not limited to the types of the network side device 12 listed above, and the embodiments of the present application are not limited in particular.
