To facilitate understanding of the technical solutions of the embodiments of the present application, the following describes the technical solutions related to the embodiments of the present application.

With people's pursuit of speed, delay, high-speed mobility, energy efficiency and the diversity and complexity of business in future life, the ^3rd Generation Partnership Project (3GPP) international standards organization began to develop 5G . The main application scenarios of 5G are: Enhanced Mobile Broadband (eMBB), Ultra Reliable Low Latency Communication (URLLC), and massive Machine Type Communication (mMTC).

On the one hand, eMBB still aims at users obtaining multimedia content, services and data, and its demand is growing rapidly. On the other hand, since eMBB may be deployed in different scenarios, such as indoors, urban areas, and rural areas, the capabilities and requirements vary greatly, so it cannot be generalized, and detailed analysis must be combined with specific deployment scenarios. Typical applications of URLLC include: industrial automation, electric power automation, telemedicine operations (surgery), traffic safety guarantee, etc. The typical characteristics of mMTC include: high connection density, small data volume, delay-insensitive services, low cost and long service life of modules, etc.

In the early deployment of NR, it is difficult to obtain complete NR coverage, so the typical network coverage is wide-area LTE coverage and NR island coverage mode. Moreover, a large number of LTE deployments are below 6GHz, and there is very little spectrum below 6GHz that can be used for 5G. Therefore, NR must study the spectrum application above 6GHz, while the coverage of high frequency bands is limited and the signal fades quickly. At the same time, in order to protect mobile operators' investment in LTE in the early stage, a working mode of tight interworking between LTE and NR is proposed.

In order to realize 5G network deployment and commercial application as soon as possible, 3GPP first completed the first 5G version, namely LTE-NR Dual Connectivity (LTE-NR Dual Connectivity, EN-DC). In EN-DC, the LTE base station serves as the master node (Master Node, MN), and the NR base station serves as the secondary node (Secondary Node, SN), connecting to the evolved packet core network (Evolved Packet Core network, EPC). In the later stage of R15, other dual connectivity (Dual Connectivity, DC) modes will be supported, namely NR-LTE Dual Connectivity (NR-LTE Dual Connectivity, NE-DC), 5GC-EN-DC, NR DC. In NE-DC, the NR base station acts as the MN, and the LTE base station acts as the SN, connecting to the 5G core network (5GC). In 5GC-EN-DC, the LTE base station acts as the MN, and the NR base station acts as the SN, connecting to the 5GC. In NR DC, the NR base station acts as the MN, and the NR base station acts as the SN, connecting to the 5GC.

The technical solutions of the embodiments of the present application can be applied not only to a dual connectivity architecture (such as an MR-DC architecture), but also to a multiple connectivity (Multiple Connectivity, MC) architecture. Typically, the MC architecture can be an MR-MC architecture.

NR can also be deployed independently. NR will be deployed on high frequencies in the future. In order to improve coverage, in 5G, the mechanism of beam sweeping is introduced to meet the coverage requirements (use space for coverage and time for space), as shown in Figure 2. After the introduction of beam sweeping, a synchronization signal needs to be sent in each beam direction. The 5G synchronization signal is given in the form of a synchronization signal block (SS/PBCH Block, SSB), including the primary synchronization signal (Primary Synchronization Signal, PSS), A secondary synchronization signal (Secondary Synchronization Signal, SSS) and a physical broadcast channel (Physical Broadcast Channel, PBCH), as shown in FIG. 3 . The synchronization signal of 5G appears periodically in the time domain in the form of a synchronization signal burst set (SS burst set). As shown in FIG. 4 , the period of the SS burst set can also be called the period of the SSB.

The number of beams (beams) actually transmitted by each cell is determined by the configuration on the network side, but the frequency point where the cell is located determines the maximum number of beams that can be configured, as shown in Table 1 below.

Frequency Range L (the maximum number of beams) (2.4)GHz or less 4 3(2.4)GHz—6GHz 8 6GHz—52.6GHz 64

Table 1

In radio resource management (Radio Resource Management, RRM) measurement, the measured reference signal may be SSB, that is, measure the SSS signal in SSB or the demodulation reference signal (Demodulation Reference Signal, DMRS) signal of PBCH to obtain beam measurement results and Cell measurement results. In addition, a terminal device in a radio resource control (Radio Resource Control, RRC) connected state may also configure a channel status indicator reference signal (Channel Status Indicator Reference Signal, CSI-RS) as a reference signal for cell measurement.

For SSB-based measurement, the actual transmission position of the SSB of each cell may be different, and the period of the SS burst set may also be different. Therefore, in order for the terminal equipment to save energy during the measurement process, the network side configures the SSB measurement timing configuration (SS/PBCH block measurement timing configuration, SMTC) for the terminal equipment. measurement, as shown in Figure 5.

Since the location of the SSB actually transmitted by each cell may be different, in order to allow the terminal device to find the location of the actual SSB transmitted as soon as possible, the network side will also configure the terminal device with the actual SSB transmission location measured by the terminal device, for example, all The union of the SSB actual transmission positions of the measured cells is shown in Table 2 below. As an example, at 3-6GHz, the length of the bitmap is 8 bits, assuming that the bitmap of the 8-bit length is 10100110, then the terminal device only needs to index 0, 2, 5, 6 for the SSBs in the candidate positions of the 8 SSBs SSB to do the measurement.

Table 2

To save energy for terminal equipment, the concept of SCG deactivation is introduced. After the SCG is deactivated, the downlink timing relationship between the terminal equipment and the PSCell may not be maintained. The terminal equipment needs to measure the measurement of the SN configuration. For the measurement configuration of the SN configuration, SMTC is generally configured for the measurement object. The purpose is to allow the terminal equipment to quickly search for the measured cell and the measured SSB position during the measurement process. purpose of electricity. In the measurement configuration of the SN configuration, the time domain position of the SMTC of the measurement object is determined based on the downlink timing of the PSCell.

However, after the SCG is deactivated, if the terminal device loses the downlink timing of the PSCell (that is, the downlink timing relationship between the terminal device and the terminal device cannot be maintained), the terminal device cannot determine the position of the SMTC in the time domain. It needs to be clarified how the end device performs the measurement of the SN configuration. To this end, the following technical solutions of the embodiments of the present application are proposed.

Fig. 6 is a schematic flow chart of the measurement method provided by the embodiment of the present application. As shown in Fig. 6, the measurement method includes the following steps:

Step 601: When the terminal device loses the downlink timing of the PSCell, the terminal device determines the measurement method for the first measurement configuration; wherein the first measurement configuration is a measurement configuration configured by the SN, and the PSCell is the SN The corresponding primary cell in the SCG.

In some optional embodiments, the technical solutions of the embodiments of the present application may be applied to a dual connectivity architecture. The dual connectivity architecture includes one MN and one SN. The cell group corresponding to the MN is called MCG. MCG includes a primary cell (PCell) and one or more secondary cells (SCell). The cell group corresponding to SN is called SCG. SCG It includes a PSCell, and optionally, also includes one or more SCells. The MN can configure the measurement configuration for the terminal device, specifically, the PCell configures the measurement configuration for the terminal device. The SN may also configure the measurement configuration for the terminal device, specifically, the PSCell configures the measurement configuration for the terminal device. The measurement configurations configured by the MN and SN for the terminal equipment are independent of each other.

In some optional embodiments, the technical solutions of the embodiments of the present application may be applied to a multi-connection architecture. The difference from the dual connectivity architecture is that the multi-connectivity architecture includes one MN and multiple SNs. For the MNs and SNs, refer to the description of the aforementioned dual connectivity architecture.

In the embodiment of the present application, the first measurement configuration is a measurement configuration configured by the SN, and the SN may send the first measurement configuration to the terminal device through an RRC connection reconfiguration message.

In some optional embodiments, the first measurement configuration includes: a measurement object list, a measurement report list and a measurement list. Wherein, the measurement list includes at least one measurement id, and each measurement id is associated with a measurement object and a measurement report. For a measurement object, an SMTC configuration will be configured for it, and the time domain position of the SMTC configuration is determined based on the downlink timing of the PSCell, that is, the time domain position of the SMTC can be determined based on the downlink timing of the PSCell.

It should be noted that the "downlink timing" in the embodiment of the present application may also be referred to as "reference timing".

In the embodiment of the present application, the SCG on the SN side can be in the activated state or the deactivated state. After the SGC is deactivated, all the cells in the SGC are in the deactivated state, so as to realize the purpose of energy saving of the terminal equipment. After the SCG is deactivated, the terminal equipment will lose the downlink timing of the PSCell. Specifically, the terminal device receives second indication information, where the second indication information is used to instruct deactivation of the SCG, wherein after the SCG is deactivated, the terminal device loses the downlink timing of the PSCell.

Here, the downlink timing of the PSCell is used by the terminal equipment to determine the time domain position of the SMTC, and then perform measurement within the SMTC window according to the time domain position of the SMTC. If the terminal device loses the downlink timing of the PSCell, the measurement mode configured for the measurement of the SN configuration is one of the following.

(1) The terminal device determines not to perform the measurement for the first measurement configuration.

Specifically, when the terminal device loses the downlink timing of the PSCell, the terminal device does not perform measurement on using the PSCell as a reference timing, that is, does not perform the measurement of the first measurement configuration (that is, the measurement of the SN configuration).

(2) The first measurement configuration includes at least the configuration information of the first measurement object; there is a second measurement object associated with the first measurement object in the second measurement configuration, and the second measurement configuration is the main The measurement configuration configured by the node MN; the terminal device determines that the measurement method for the first measurement object is the first measurement method, wherein the first measurement method includes: the terminal device corresponds to The SMTC is configured to perform measurements on the first measurement object.

In an optional manner, the association relationship refers to that the SSB frequency points and/or subcarrier intervals of the measurement objects are the same.

Here, the SMTC configuration corresponding to the second measurement object is used to determine the first SMTC, and the time domain position of the first SMTC is determined based on the downlink timing of the PCell, and the PCell is the primary cell group MCG corresponding to the MN. In the primary cell, the first SMTC is the SMTC used by the first measurement object to perform measurement.

Specifically, when the terminal device loses the downlink timing of the PSCell, the terminal device uses the measurement configuration configured by the MN for the first measurement object (that is, the second measurement configuration), the SSB frequency point of the first measurement object is the same and the subcarrier The SMTC corresponding to the second measurement object with the same interval is used as the SMTC used to measure the first measurement object. Here, the second measurement object in the measurement configuration configured by the MN is, for example, measObjectNR.

(3) The first measurement configuration includes at least configuration information of a first measurement object; the terminal device determines that the measurement method for the first measurement object is a second measurement method, where the second measurement method includes: The terminal device performs measurement on the first measurement object based on the first SSB period.

In some optional embodiments, the first SSB period is 5ms or 10ms.

Specifically, when the terminal device loses the downlink timing of the PSCell, the terminal device assumes that the SSB period is 5ms, and performs measurement on the first measurement object according to the 5ms SSB period.

It should be noted that the SSB period may also be referred to as the period of the SS burst set.

In an optional manner, the method further includes: the terminal device receiving first indication information, where the first indication information is used to indicate that the measurement method for the first measurement object is the first measurement in the above solution The method or the second measurement method in the above scheme.

The foregoing technical solutions of the embodiments of the present application can be embodied by the contents shown in the following table 3:

table 3

(4) The first measurement configuration includes at least configuration information of a third measurement object; there is no measurement object associated with the third measurement object in the second measurement configuration, and the second measurement configuration is an MN configuration The measurement configuration; the terminal device determines that the measurement mode for the third measurement object is relaxed measurement.

In an optional manner, the association relationship refers to that the SSB frequency points and/or subcarrier intervals of the measurement objects are the same.

Here, when the SCG is deactivated, the measurement of the SN configuration can be relaxed, so as to achieve the purpose of power saving of the terminal equipment. Specifically, if the SSB frequency point and/or subcarrier spacing of a certain measurement object configured by the SN is the same as the SSB frequency point and/or subcarrier spacing of a certain measurement object configured by the MN, the measurement object configured by the SN cannot perform Relax measurement. If the SSB frequency and/or subcarrier spacing of a certain measurement object configured by the SN is different from the SSB frequency and/or subcarrier spacing of all measurement objects configured by the MN, the measurement object configured by the SN can perform relaxed measurement.

In the embodiment of the present application, the relaxation measurement may be implemented by, but not limited to, the following: prolonging the measurement period of the SSB.
