In order 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 the pursuit of speed, delay, high speed mobility, energy efficiency and diversity and complexity of future life business, the third generation partnership project (3 ^rd Generation Partnership Project,3 GPP) international standards organization began developing 5G. The main application scenario of 5G is: enhanced mobile ultra-wideband (Enhance Mobile Broadband, emmbb), low latency high reliability communications (Ultra Reliable Low Latency Communication, URLLC), large scale machine type communications (massive Machine Type Communication, mctc).

On the one hand, embbs still target users to obtain multimedia content, services and data, and their demand is growing very rapidly. On the other hand, since an eMBB may be deployed in different scenarios, such as indoors, urban, rural, etc., its capabilities and requirements are also quite different, so that detailed analysis must be performed in connection with a specific deployment scenario, not in general. Typical applications of URLLC include: industrial automation, electric power automation, remote medical operation (surgery), traffic safety guarantee and the like. Typical characteristics of mctc include: high connection density, small data volume, delay insensitive traffic, low cost and long service life of the module, etc.

At early deployment of NRs, full NR coverage is difficult to acquire, so typical network coverage is wide area LTE coverage and island coverage mode of NRs. And a large amount of LTE is deployed below 6GHz, and the frequency spectrum below 6GHz which can be used for 5G is few. NR must study spectral applications above 6GHz while high-band coverage is limited and signal fading is fast. Meanwhile, in order to protect the mobile operators from early investment in LTE, a tightly matched (tight interworking) working mode between LTE and NR is proposed.

To enable 5G network deployment and commercial applications as soon as possible, 3GPP first completes the first 5G release, LTE-NR dual connectivity (LTE-NR Dual Connectivity, EN-DC). In EN-DC, an LTE base station serves as a Master Node (MN), and an NR base station serves as a Secondary Node (SN), and is connected to an evolved packet core (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, an NR base station serves as MN, and an LTE base station serves as SN, and is connected to a 5G core network (5 GC). In 5GC-EN-DC, an LTE base station is used as an MN, an NR base station is used as an SN, and the 5GC is connected. In NR DC, NR base station is as MN, NR base station is as SN, and 5GC is connected.

The technical solution of the embodiments of the present application may be applied not only to a dual-connection architecture (such as an MR-DC architecture), but also to a multi-connection (Multiple Connectivity, MC) architecture, which may typically be an MR-MC architecture.

NR can also be deployed independently. NR will be deployed in the future at high frequencies, and in order to improve coverage, in 5G, the requirements of coverage (coverage with space and space with time) are met by introducing a beam scanning (beam scanning) mechanism, as shown in fig. 2. After the introduction of beam sweep, a synchronization signal needs to be transmitted in each beam direction, and the synchronization signal of 5G is given in the form of a Synchronization Signal Block (SSB) including a primary synchronization signal (Primary Synchronisation Signal, PSS), a secondary synchronization signal (Secondary Synchronisation Signal, SSs), and a physical broadcast channel (Physical Broadcast Channel, PBCH), as shown in fig. 3. The synchronization signal of 5G occurs periodically in the time domain in the form of a synchronization signal burst (SS burst set), and as shown in fig. 4, the period of SS burst set may also be referred to as the period of SSB.

The number of beams (beams) actually transmitted by each cell is determined by the network side configuration, 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 (maximum beam number)
(2.4) GHz or lower	4
3(2.4)GHz—6GHz	8
6GHz—52.6GHz	64

TABLE 1

In radio resource management (Radio Resource Management, RRM) measurements, the measured reference signals may be SSBs, i.e. the SSS signals in the SSBs or the demodulation reference signals (Demodulation Reference Signal, DMRS) signals of the PBCH are measured to obtain beam measurements as well as cell measurements. In addition, the terminal device in a radio resource control (Radio Resource Control, RRC) connected state may also configure a channel state indication reference signal (Channel Status Indicator Reference Signal, CSI-RS) as a reference signal for cell measurement.

The actual transmission position of SSB may be different for each cell for SSB-based measurements, as may the period of SS burst set. So in order for the terminal device to save energy during the measurement, the network side configures the terminal device with SSB measurement timing configuration (SS/PBCH block measurement timing configuration, SMTC), which can be understood as the measurement window of SSB, and the terminal device only needs to perform measurement in SMTC, as shown in fig. 5.

Since the location of the SSB actually transmitted by each cell may be different, in order for the terminal device to find the location of the SSB actually transmitted as soon as possible, the network side may also configure the terminal device with the location of the SSB actually transmitted measured by the terminal device, for example, a union of the locations of the SSBs actually transmitted by all the measurement cells, as shown in table 2 below. As an example, at 3-6GHz, the length of the bitmap is 8 bits, and assuming that the 8-bit length bitmap is 10100110, the terminal device only needs to measure SSBs with

SSB indexes

0,2,5,6 in candidate locations of 8 SSBs.

TABLE 2

For the power saving of the terminal equipment, the concept of SCG deactivation was introduced. After SCG deactivation, the downlink timing relationship between the terminal device and PSCell may not be maintained. And the terminal equipment needs to measure the measurement of the SN configuration, and for the measurement configuration of the SN configuration, the SMTC is generally configured for a measurement object, so that the terminal equipment can quickly search a measured cell and a measured SSB position in the measurement process, and the purpose of saving power of the terminal equipment is achieved. In the measurement configuration of the SN configuration, the time domain position of SMTC of the measurement object is determined based on the downlink timing of the PSCell.

However, after SCG deactivation, if the terminal device loses the downlink timing of PSCell (i.e., the downlink timing relationship between the terminal device and the terminal device cannot be maintained), the terminal device cannot determine the SMTC position in the time domain. The measurement of how the terminal device performs the SN configuration needs to be explicit. For this reason, the following technical solutions of the embodiments of the present application are proposed.

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

step 601: under the condition that terminal equipment loses the downlink timing of a PSCell, the terminal equipment determines a measurement mode aiming at first measurement configuration; the first measurement configuration is configured as measurement configuration of SN configuration, and the PSCell is a primary cell in the SCG corresponding to the SN.

In some alternative embodiments, the technical solutions of the embodiments of the present application may be applied to a dual connection architecture. The dual connectivity architecture comprises a MN and a SN, wherein the cell group corresponding to the MN is referred to as MCG, the MCG comprises a primary cell (PCell) and one or more secondary cells (scells), the cell group corresponding to the SN is referred to as SCG, and the SCG comprises a PSCell and optionally one or more scells. The MN may configure a measurement configuration for the terminal device, in particular, the PCell configures a measurement configuration for the terminal device. The SN may also configure a measurement configuration for the terminal device, specifically, the PSCell configures a measurement configuration for the terminal device. The measurement configurations of the MN and SN for the terminal device configuration are independent of each other.

In some alternative 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 a plurality of SNs, which refer to the description of the dual connectivity architecture described above.

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

In some alternative embodiments, the first measurement configuration comprises: the system comprises a measurement object list, a measurement report list and a measurement list. The measurement list comprises at least one measurement id, and each measurement id is associated with one measurement object and one measurement report. For a measurement object, an SMTC configuration is configured, 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 may be determined based on the downlink timing of the PSCell.

The "downlink timing" in the embodiment of the present application may also be referred to as "reference timing".

In the embodiment of the application, the SCG on the SN side can be in an activated state or a deactivated state, and after the SGC is deactivated, all cells in the SGC are in the deactivated state, so that the purpose of saving energy of the terminal equipment is achieved. After SCG deactivation, the terminal device may lose the PSCell downlink timing. Specifically, the terminal device receives second indication information, where the second indication information is used to indicate the SCG to deactivate, and after the SCG is deactivated, the terminal device loses the downlink timing of the PSCell.

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

The terminal device determines not to perform measurements for the first measurement configuration.

Specifically, after the terminal device loses the downlink timing of the PSCell, the terminal device does not perform measurement for reference timing using the PSCell, i.e., does not perform measurement of the first measurement configuration (i.e., measurement of the SN configuration).

(II) the first measurement configuration at least comprises configuration information of a first measurement object; a second measurement object with an association relation with the first measurement object exists in a second measurement configuration, wherein the second measurement configuration is configured by a master node MN; the terminal device determines that a measurement mode aiming at the first measurement object is a first measurement mode, wherein the first measurement mode comprises: the terminal device performs measurement for the first measurement object based on SMTC configuration corresponding to the second measurement object.

In an alternative manner, the association relationship refers to: the SSB frequency points and/or the subcarrier intervals of the synchronous signal blocks of the measuring objects are the same.

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

Specifically, after the terminal device loses the downlink timing of the PSCell, in a measurement configuration (i.e., a second measurement configuration) configured by the terminal device and for the first measurement object, SMTC corresponding to a second measurement object having the same SSB frequency point and the same subcarrier spacing of the first measurement object is used as SMTC for measuring the first measurement object. Here, the second measurement object in the measurement configuration of the MN configuration is, for example, measObjectNR.

(III) the first measurement configuration at least comprises configuration information of a first measurement object; the terminal device determines that the measurement mode aiming at the first measurement object is a second measurement mode, wherein the second measurement mode comprises: the terminal device performs measurement for the first measurement object based on a first SSB period.

In some alternative 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 for the first measurement object according to the SSB period of 5 ms.

Note that the SSB period may also be referred to as a period of SS burst set.

In an alternative, the method further comprises: the terminal device receives first indication information, where the first indication information is used to indicate that a measurement mode for the first measurement object is a first measurement mode in the above scheme or a second measurement mode in the above scheme.

The above technical solution of the embodiments of the present application may be represented by the following contents shown in table 3:

TABLE 3 Table 3

(fourth) the first measurement configuration includes at least configuration information of a third measurement object; in a second measurement configuration, there is no measurement object having an association relationship with the third measurement object, the second measurement configuration being a MN configured measurement configuration; the terminal device determines that the measurement mode for the third measurement object is a relaxation measurement.

Here, after the SCG is deactivated, the measurement of the SN configuration may be relaxed, thereby achieving the purpose of saving power for the terminal device. Specifically, if the SSB frequency points and/or subcarrier spacing of a certain measurement object configured by the SN is the same as the SSB frequency points and/or subcarrier spacing of a certain measurement object configured by the MN, the measurement object configured by the SN cannot perform a relaxation measurement. If the SSB frequency points and/or subcarrier spacing of a certain measurement object configured by the SN is different from the SSB frequency points and/or subcarrier spacing of all measurement objects configured by the MN, the measurement object configured by the SN can perform relaxation measurement.

In embodiments of the present application, relaxation measurements may be achieved, but are not limited to, by: the measurement period of SSB is prolonged.
