The communication system 100 may include a network device 110, which may be a device that communicates with a terminal 120 (or a communication terminal, terminal).

[0038] It should be understood that the terms "system" and "network" are often used interchangeably in this document. The term "and / or" in this document merely describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. Furthermore, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0039] To facilitate understanding of the technical solutions in the embodiments of this application, the technical solutions related to the embodiments of this application will be described below.

[0040] With people's pursuit of speed, latency, high-speed mobility, and energy efficiency, and the increasing diversity and complexity of business in future life, the third-generation partnership program (3GPP) is therefore being developed. rd The Generation Partnership Project (3GPP) international standards organization has begun developing 5G. The main application scenarios for 5G are: Enhanced Mobile Broadband (eMBB), Ultra Reliable Low Latency Communication (URLLC), and Massive Machine Type Communication (mMTC).

[0041] On the one hand, eMBB still aims to provide users with multimedia content, services, and data, and its demand is growing rapidly. On the other hand, because eMBB may be deployed in different scenarios, such as indoors, urban areas, and rural areas, its capabilities and needs vary considerably. Therefore, generalizations cannot be made; a detailed analysis based on the specific deployment scenario is necessary. Typical applications of URLLC include industrial automation, power automation, remote medical operations (surgery), and traffic safety assurance. Typical characteristics of mMTC include high connection density, small data volume, latency-insensitive services, low module cost, and long service life.

[0042] In the early stages of NR deployment, complete NR coverage was difficult to achieve, so typical network coverage consisted of wide-area LTE coverage and isolated NR coverage. Furthermore, a large portion of LTE deployment was below 6 GHz, leaving very little spectrum available for 5G below 6 GHz. Therefore, NR had to explore spectrum applications above 6 GHz, but high-frequency band coverage was limited and signal fading was rapid. Simultaneously, to protect mobile operators' initial investments in LTE, a tight interworking mode between LTE and NR was proposed.

[0043] To expedite 5G network deployment and commercial applications, 3GPP first completed the first 5G release, LTE-NR Dual Connectivity (EN-DC). In EN-DC, the LTE base station acts as the Master Node (MN), and the NR base station acts as the Secondary Node (SN), connecting to the Evolved Packet Core network (EPC). Later in Release 15, other Dual Connectivity (DC) modes will be supported, namely NR-LTE Dual Connectivity (NE-DC), 5GC-EN-DC, and 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 both the MN and SN, connecting to the 5GC.

[0044] The technical solutions of this application can be applied not only to dual-connectivity architectures (such as MR-DC architecture) but also to multiple-connectivity (MC) architectures. Typically, the MC architecture can be an MR-MC architecture.

[0045] NR can also be deployed independently. NR will be deployed at high frequencies in the future. To improve coverage, 5G introduces a beam sweeping mechanism to meet coverage requirements (trading space for coverage, and time for space), such as... Figure 2 As shown. After introducing beam sweeping, a synchronization signal needs to be transmitted in each beam direction. The 5G synchronization signal is given in the form of a synchronization signal block (SS / PBCH Block, SSB), which includes the primary synchronization signal (PSS), the secondary synchronization signal (SSS), and the physical broadcast channel (PBCH), as shown. Figure 3 As shown, 5G synchronization signals appear periodically in the time domain in the form of synchronization signal burst sets (SSburst sets), such as... Figure 4 As shown, the period of the SS burst set can also be called the period of the SSB.

[0046] The actual number of beams transmitted in each cell is determined by the network-side configuration, but the frequency of the cell determines the maximum number of beams that can be configured, as shown in Table 1 below.

[0047] (2.4) GHz and below 4 3(2.4) GHz—6 GHz 8 6GHz—52.6GHz 64

[0048] Table 1

[0049] In Radio Resource Management (RRM) measurements, the reference signal for measurement can be the SSB (Self-Signal Block), i.e., the SSS signal within the SSB, or the Demodulation Reference Signal (DMRS) signal of the PBCH, to obtain beam measurement results and cell measurement results. Furthermore, terminal equipment in Radio Resource Control (RRC) connection state can also configure the Channel Status Indicator Reference Signal (CSI-RS) as the reference signal for cell measurements.

[0050] For SSB-based measurements, the actual transmission location of the SSB in each cell may differ, and the period of the SS burst set may also vary. Therefore, to save energy for terminal devices during measurement, the network side configures an SSB measurement timing configuration (SMTC) for the terminal devices. The SMTC can be understood as the measurement window for the SSB; the terminal device only needs to perform measurements within the SMTC. Figure 5 As shown.

[0051] Since the actual location of the transmitted SSB may differ in each cell, the network side configures the terminal device with the actual SSB transmission location measured by the terminal device to help it quickly locate the transmitted SSB. For example, this could be the union of the actual SSB transmission locations of all measured cells, as shown in Table 2. As an example, in the 3-6 GHz range, the bitmap length is 8 bits. Assuming the 8-bit bitmap is 10100110, the terminal device only needs to measure the SSBs with indices 0, 2, 5, and 6 from the eight candidate SSB locations.

[0052]

[0053] Table 2

[0054] To save energy in terminal devices, the concept of SCG deactivation is introduced. After SCG deactivation, the downlink timing relationship between the terminal device and the PSCell may become unmaintainable. The terminal device needs to perform measurements configured by the SN. For SN-configured measurements, an SMTC is typically configured for the measured object as well. This allows the terminal device to quickly search for the measured cell and SSB location during the measurement process, thus saving power. In the SN-configured measurement settings, the time-domain location of the measured object's SMTC is determined based on the downlink timing of the PSCell.

[0055] However, after SCG deactivation, if the terminal device loses the downlink timing of PSCell (i.e., the downlink timing relationship between terminal devices cannot be maintained), the terminal device cannot determine the location of SMTC in the time domain. How the terminal device performs SN configuration measurements needs to be clearly defined. Therefore, the following technical solution based on embodiments of this application is proposed.

[0056] Figure 6 This is a schematic flowchart of the measurement method provided in the embodiments of this application, as shown below. Figure 6 As shown, the measurement method includes the following steps:

[0057] Step 601: When the terminal device loses downlink timing of PSCell, the terminal device determines the measurement mode for the first measurement configuration; wherein, the first measurement configuration is the measurement configuration configured by the SN, and the PSCell is the primary cell in the SCG corresponding to the SN.

[0058] In some optional embodiments, the technical solutions of this application can be applied to a dual-connectivity architecture. The dual-connectivity architecture includes a MN and a SN, wherein the cell group corresponding to the MN is called an MCG, the MCG includes one primary cell (PCell) and one or more secondary cells (SCells), and the cell group corresponding to the SN is called an SCG, the SCG includes one PSCell, and optionally, one or more SCells. The MN can configure measurement configurations for the terminal device; specifically, the PCell configures measurement configurations for the terminal device. The SN can also configure measurement configurations for the terminal device; specifically, the PSCell configures measurement configurations for the terminal device. The measurement configurations configured for the terminal device by the MN and SN are independent of each other.

[0059] In some optional embodiments, the technical solutions of this application can be applied to a multi-connection architecture. The difference from a dual-connection architecture is that a multi-connection architecture includes one MN and multiple SNs, where MN and SNs can be referred to the description of the aforementioned dual-connection architecture.

[0060] In this embodiment of the application, the first measurement configuration is the measurement configuration configured by the SN, and the SN can send the first measurement configuration to the terminal device through the RRC connection reconfiguration message.

[0061] In some optional embodiments, the first measurement configuration includes: a measurement object list, a measurement reporting list, and a measurement list. 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 is configured. The time-domain position of this 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.

[0062] It should be noted that the "downlink timing" in the embodiments of this application can also be referred to as "reference timing".

[0063] In this embodiment, the SCG on the SN side can be in an active or deactivated state. After the SCG is deactivated, all cells in the SCG are in a deactivated state, thereby achieving energy saving for the terminal device. After the SCG is deactivated, the terminal device will lose downlink timing of the PSCell. Specifically, the terminal device receives second indication information, which is used to instruct the SCG to be deactivated, wherein after the SCG is deactivated, the terminal device loses downlink timing of the PSCell.

[0064] Here, the downlink timing of PSCell is used by the terminal device to determine the time domain location of SMTC, and then perform measurements within the SMTC window based on the time domain location of SMTC. If the terminal device loses the downlink timing of PSCell, the measurement method configured for SN will be one of the following.

[0065] (i) The terminal device determines that it will not perform the measurement for the first measurement configuration.

[0066] Specifically, when the terminal device loses the downlink timing of PSCell, the terminal device does not perform measurements for which PSCell is used as a reference timing, that is, it does not perform measurements of the first measurement configuration (i.e., measurements of the SN configuration).

[0067] (ii) The first measurement configuration includes at least the configuration information of the first measurement object; the second measurement configuration contains a second measurement object that is associated with the first measurement object, and the second measurement configuration is the measurement configuration of the master node MN; the terminal device determines the measurement method for the first measurement object as the first measurement method, wherein the first measurement method includes: the terminal device performs a measurement for the first measurement object based on the SMTC configuration corresponding to the second measurement object.

[0068] In an alternative approach, the correlation refers to the fact that the synchronization signal block SSB frequency point and / or subcarrier spacing of the measurement objects are the same.

[0069] Here, the SMTC configuration corresponding to the second measurement object is used to determine the first SMTC. The time domain position of the first SMTC is determined based on the downlink timing of the PCell. The PCell is the primary cell in the primary cell group (MCG) corresponding to the MN. The first SMTC is the SMTC used by the first measurement object to perform the measurement.

[0070] Specifically, when the terminal device loses downlink timing of the PSCell, the SMTC corresponding to the second measurement object (which has the same SSB frequency and subcarrier spacing as the first measurement object) in the measurement configuration (i.e., the second measurement configuration) used by the terminal device for measuring the first measurement object is selected as the SMTC used for measuring the first measurement object. Here, the second measurement object in the measurement configuration of the MN configuration is, for example, measObjectNR.

[0071] (iii) The first measurement configuration includes at least the configuration information of the first measurement object; the terminal device determines the measurement method for the first measurement object as the second measurement method, wherein the second measurement method includes: the terminal device performs a measurement for the first measurement object based on the first SSB cycle.

[0072] In some alternative embodiments, the first SSB period is 5ms or 10ms.

[0073] Specifically, when the terminal device loses the downlink timing of PSCell, the terminal device assumes that the SSB period is 5ms and performs the measurement for the first measurement object according to the 5ms SSB period.

[0074] It should be noted that the SSB period can also be called the period of the SS burst set.

[0075] In an optional embodiment, the method further includes: the terminal device receiving first indication information, the first indication information being used to indicate that the measurement method for the first measurement object is either the first measurement method in the above scheme or the second measurement method in the above scheme.

[0076] The above-described technical solutions of this application embodiment can be embodied in the following Table 3:

[0077]

[0078] Table 3

[0079] (iv) The first measurement configuration includes at least the configuration information of the 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 measurement configuration; the terminal device determines that the measurement method for the third measurement object is relaxation measurement.

[0080] In an alternative approach, the correlation refers to the fact that the synchronization signal block SSB frequency point and / or subcarrier spacing of the measurement objects are the same.

[0081] Here, when the SCG is deactivated, the measurements configured by the SN can be relaxed, thereby saving power for the terminal device. Specifically, if the SSB frequency and / or subcarrier spacing of a measurement object configured by the SN is the same as the SSB frequency and / or subcarrier spacing of a measurement object configured by the MN, then the measurement object configured by the SN cannot be relaxed for measurement. If the SSB frequency and / or subcarrier spacing of a measurement object configured by the SN is different from the SSB frequency and / or subcarrier spacing of all measurement objects configured by the MN, then the measurement object configured by the SN can be relaxed for measurement.

[0082] In this embodiment of the application, relaxation of measurement can be achieved, but is not limited to, by extending the measurement period of SSB.

[0086] In some alternative embodiments, the determining unit 701 is configured to determine that a measurement for the first measurement configuration is not performed.

[0088] The determining unit 701 is used to determine that the measurement method for the first measurement object is a first measurement method, wherein the first measurement method includes: the terminal device performing a measurement for the first measurement object based on the SMTC configuration corresponding to the second measurement object.

[0089] In some alternative embodiments, the SMTC configuration corresponding to the second measurement object is used to determine the first SMTC. The time domain location of the first SMTC is determined based on the downlink timing of the PCell, where the PCell is the primary cell in the MCG corresponding to the MN, and the first SMTC is the SMTC used by the first measurement object to perform the measurement.

[0091] The determining unit 701 is used to determine that the measurement method for the third measurement object is relaxation measurement.

[0093] In some alternative embodiments, the first measurement configuration includes at least the configuration information of the first measurement object;

[0094] The determining unit 701 is used to determine that the measurement method for the first measurement object is a second measurement method, wherein the second measurement method includes: the terminal device performing a measurement for the first measurement object based on a first SSB cycle.
