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.

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) GHzLower part(s)	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 power during 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 a 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

In some mobility scenarios, for example, a handover procedure, a primary and Secondary Cell (Primary Secondary Cell, PSCell) adding procedure, a PSCell changing procedure, a Secondary Cell (SCell) adding procedure, an SCell changing procedure, a redirection procedure, etc., the network device may configure SMTC for the terminal device when searching for the target Cell, and the purpose of accelerating the search for the target Cell may be achieved through SMTC.

However, in the case where the network device does not configure SMTC of the target cell for the terminal device, it is clear how to achieve fast search of the target cell. For this reason, the following technical solutions of the embodiments of the present application are proposed.

In the technical solution of the embodiment of the present application, in the case where the network device does not configure SMTC of the target cell for the terminal device, the SMTC configured in the RRM measurement configuration (hereinafter referred to as the first measurement configuration) and the measurement object in which the target cell has the same SSB frequency point and/or SSB subcarrier spacing is used as the SMTC used for searching the target cell.

In the RRM measurement configuration, in order to finely measure the measurement of the corresponding cell of the serving frequency point, an additional SMTC is configured in addition to the original SMTC in the configuration of a measurement object, where the additional SMTC is associated with a physical cell identifier (Physical Cell Identity, PCI) list, and is used to indicate which cells of the frequency point can be used for measurement. The following table 3 gives the configuration contents of the measurement object (measObjectNR) of the NR frequency points, where "SMTC1" corresponds to the original SMTC and "SMTC2" corresponds to the additional SMTC.

TABLE 3 Table 3

In the case where 2 SMTCs are configured in the configuration of one measurement object, it is necessary to specify which SMTC is used as the SMTC used for the target cell search.

Fig. 6 is a flowchart of a method for determining SMTC according to an embodiment of the present application, as shown in fig. 6, where the method for determining SMTC includes the following steps:

step 601: the method comprises the steps that terminal equipment receives a first RRC message sent by network equipment, wherein the first RRC message carries configuration information of a target cell; and if the configuration information of the target cell does not comprise the SMTC configuration of the target cell, the terminal equipment determines a first measurement object with an association relation with the target cell from the first measurement configuration, wherein the first measurement object is associated with the first SMTC configuration and the second SMTC configuration.

In this embodiment of the present application, the network device is an access network element, and optionally, the network device may be a base station.

In this embodiment, the first measurement configuration is received by the terminal device before the first RRC message.

In some alternative embodiments, the first measurement configuration is an RRM measurement configuration. The RRM measurement configuration may refer to the description of the related art scheme described above. For ease of understanding, some descriptions will be made herein of RRM measurement configurations, which include configurations of one or more measurement objects, SSB frequency point information, SSB subcarrier spacing information, and 1 or 2 SMTC configurations for each measurement object's configuration. It should be noted that some measurement objects will be associated with 1 SMTC configuration (i.e. the configuration of the measurement object includes 1 SMTC configuration), and some measurement objects will be associated with 2 SMTC configurations (i.e. the configuration of the measurement object includes 2 SMTC configurations, for example, table 3 illustrates an example of 2 SMTC configurations).

In the embodiment of the present application, SMTC is configured to determine a time window for measuring SSB, and SMTC may be understood as an SSB measurement window, and description of SMTC may be replaced by an SMTC window. In some alternative embodiments, the SMTC configuration comprises at least one of the following information: the period of SMTC, the length of SMTC, the bias of SMTC. Wherein the offset of the SMTC is used to determine the starting location of the SMTC.

The measurement (i.e., search) of one cell is performed by measuring the SSB of the cell. In order to enable the terminal device to quickly search for the target cell, the target cell may be searched based on one SMTC configuration, specifically, the terminal device searches for an SSB corresponding to the target cell in the corresponding SMTC according to the SMTC configuration.

In the embodiment of the present application, in a mobility scenario, a network device configures configuration information of a target cell for a terminal device, and if the configuration information of the target cell includes SMTC configuration of the target cell, the terminal device determines to search for SMTC used by the target cell according to the SMTC configuration; if the configuration information of the target cell does not include the SMTC configuration of the target cell, the terminal device determines a first measurement object having an association relationship with the target cell from the first measurement configuration, and further determines SMTC used for searching the target cell according to the SMTC configuration of the first measurement object.

A description is given below of how to determine a first measurement object having an association relationship with the target cell from a first measurement configuration.

In some optional embodiments, the first RRC message is an RRC release message, where the RRC release message carries SSB frequency point information and/or SSB subcarrier spacing information of the target cell. And the terminal equipment determines a measurement object with the SSB frequency point and/or the SSB subcarrier interval from a first measurement configuration according to the SSB frequency point information and/or the SSB subcarrier interval information of the target cell, and the measurement object is used as a first measurement object.

In the RRC redirection process, the network device sends an RRC release message to the terminal device, where the RRC release message carries configuration information of the target cell, and the configuration information of the target cell includes: SSB frequency point information and SSB subcarrier spacing information of the target cell. And under the condition that the configuration information of the target cell does not contain the SMTC configuration, the terminal equipment determines a measurement object with the SSB frequency point and/or the SSB subcarrier interval from the RRM measurement configuration according to the SSB frequency point information and/or the SSB subcarrier interval information of the target cell. In one example, the content carried in the RRC release message is referred to table 4 below.

TABLE 4 Table 4

Referring to table 4, the terminal device acquires SSB frequency point information of the target cell according to the following information paths in the RRC release message:

RedirectedCarrierInfo→CarrierInfoNR→carrierFreq。

referring to table 4, the terminal device acquires SSB subcarrier spacing information to the target cell according to the following information paths in the RRC release message:

RedirectedCarrierInfo→CarrierInfoNR→ssbSubcarrierSpacing。

and the terminal equipment determines a measurement object, such as MeasObjectNR, with the same frequency point and subcarrier spacing in the RRM measurement configuration according to the acquired SSB frequency point information and/or SSB subcarrier spacing information of the target cell.

In some optional embodiments, the first RRC message is an RRC reconfiguration message, where the RRC reconfiguration message carries SSB frequency point information and/or SSB subcarrier spacing information of the target cell. And the terminal equipment determines a measurement object with the SSB frequency point and/or the SSB subcarrier interval from a first measurement configuration according to the SSB frequency point information and/or the SSB subcarrier interval information of the target cell, and the measurement object is used as a first measurement object.

In a handover procedure (such as an NR PCell handover procedure, an NR PSCell handover procedure), an NR PSCell addition procedure, or a PSCell change procedure, or an SCell addition procedure, or an SCell change procedure, etc., the network device sends an RRC reconfiguration message to the terminal device, where the RRC reconfiguration message carries configuration information of a target cell, where the configuration information of the target cell includes: SSB frequency point information and SSB subcarrier spacing information of the target cell. And under the condition that the configuration information of the target cell does not contain the SMTC configuration, the terminal equipment determines a measurement object with the SSB frequency point and/or the SSB subcarrier interval from the RRM measurement configuration according to the SSB frequency point information and/or the SSB subcarrier interval information of the target cell. In one example, the content carried by the RRC reconfiguration message is referred to table 5 below.

TABLE 5

Referring to table 5, the terminal device acquires SSB frequency point information of the target cell according to the following information paths in the RRC reconfiguration message:

ServingCellConfigCommo→DownlinkConfigCommon→FrequencyInfoDL→absoluteFrequencySSB。

referring to table 5, the terminal device acquires SSB subcarrier spacing information to the target cell according to the following information paths in the RRC reconfiguration message:

CellGroupConfig→SpCellConfig→ReconfigurationWithSync→ServingCe llConfigCommon→ssbSubcarrierSpacing。

Step 602: the terminal device determines a target SMTC configuration from the first SMTC configuration and the second SMTC configuration, the target SMTC configuration being used to determine an SMTC to use for searching the target cell.

In the embodiment of the application, the terminal device may determine the target SMTC configuration in the following manner.

Mode one

In some optional embodiments, if the frequency point of the target cell is the same as the frequency point of the original serving cell and/or the physical cell identifier PCI of the target cell belongs to the PCI list associated with the second SMTC configuration, the terminal device determines the second SMTC configuration as the target SMTC configuration. And if the frequency point of the target cell is different from the frequency point of the original service cell and/or the PCI of the target cell does not belong to the PCI list associated with the second SMTC configuration, the terminal equipment determines the first SMTC configuration as the target SMTC configuration.

For example: taking the first measurement object as MeasObjectNR as an example, configuration information of the MeasObjectNR includes a smtc1 configuration and a smtc2 configuration; if the frequency point of the target cell is the same as the frequency point of the serving cell before the RRC release message is received and/or the PCI of the target cell is in a PCI list associated with the SMTC2, the SMTC2 in the MeasObjectNR is used as a target SMTC; otherwise, use SMTC1 in MeasObjectNR as the target SMTC.

For example: taking the first measurement object as MeasObjectNR as an example, configuration information of the MeasObjectNR includes a smtc1 configuration and a smtc2 configuration; if the frequency point of the target cell is the same as the frequency point of the source cell or the original serving cell, and/or if the PCI of the target cell (i.e., the physiocellid configured in ServingCellConfigCommo in table 5) is in the PCI list associated with SMTC2, then use SMTC2 in MeasObjectNR as the target SMTC; otherwise, use SMTC1 in MeasObjectNR as the target SMTC.

In the foregoing solution, the second SMTC configuration is at least used for determining a period of the second SMTC, the first SMTC configuration is at least used for determining a period of the first SMTC, and the period of the second SMTC is smaller than the period of the first SMTC.

As an example, the first SMTC corresponds to SMTC1 in table 3, the second SMTC corresponds to SMTC2 in table 3, and the period of SMTC2 is smaller than that of SMTC1, in other words, the period of SMTC2 is shorter than that of SMTC1, so that a target cell can be found faster by searching according to SMTC 2.

In this embodiment of the present application, after determining the target SMTC configuration in the above manner, the terminal device determines, based on the target SMTC configuration, an SMTC used for searching the target cell, and searches the target cell using the SMTC.

Mode two

In some alternative embodiments, the terminal device defaults to determining the first SMTC configuration as a target SMTC configuration.

Here, regardless of the mobility scenario, if the network device does not configure SMTC configuration of the target cell, the terminal device performs search for the target cell using SMTC configuration corresponding to SMTC1 configured in the measurement object having the same SSB frequency point and SSB subcarrier spacing as the target cell.

In the above scheme, if the terminal device does not determine the first measurement object having the association relationship with the target cell from the first measurement configuration, the terminal device searches the target cell according to a default SMTC configuration. Here, the default SMTC configuration is used to determine a default SSB period, and the terminal device may search for the target cell according to the default SSB period. As an example, the default SSB period is, for example, 5ms. Of course, the default SSB period may also be other values, and the protocol may specify the value of the default SSB period.

In the technical scheme of the embodiment of the application, it is clear how the terminal equipment determines the measurement object according to the SSB frequency point and the SSB subcarrier interval, and further obtains the target SMTC configuration according to the configuration of the measurement object, thereby achieving the purpose of quickly searching the target cell according to the target SMTC configuration.

In some optional embodiments, the determining unit 702 is configured to determine the first SMTC configuration as the target SMTC configuration if the frequency point of the target cell and the frequency point of the original serving cell are different and/or the PCI of the target cell does not belong to the PCI list associated with the second SMTC configuration.

In some alternative embodiments, the determining unit 702 is configured to determine the first SMTC configuration as the target SMTC configuration by default.

In some alternative embodiments, the second SMTC configuration is used at least to determine a period of the second SMTC, the first SMTC configuration is used at least to determine a period of the first SMTC, and the period of the second SMTC is less than the period of the first SMTC.
