Description

Measurement configuration method and device, terminal equipment and network equipment

Technical Field

The embodiment of the application relates to the technical field of mobile communication, in particular to a measurement configuration method and device, terminal equipment and network equipment.

Background

For measurements based on Synchronization Signal Blocks (SSBs), the actual transmission position of SSBs per cell may be different, as may the period of the synchronization signal burst set (SS burst set). So, in order to save energy in the measurement process, the network side configures the SSB measurement timing configuration (SSB Measurement Timing Configuration, SMTC) for the terminal device, and the terminal device only needs to perform measurement in the SMTC window.

To meet the cell measurement requirements of different SSB periods, an additional SMTC configuration is introduced, the original SMTC configuration being suitable for cells with shorter SSB periods, and the newly introduced SMTC configuration being suitable for cells with longer SSB periods. On the other hand, only one SSB measurement (SSB-tomeure) configuration is currently configured on the standard, and is used for indicating an index (index) set of SSBs to be measured in the SMCT window. But for two SMTC configurations, how to use SSB measurement configurations has not been clear.

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.

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 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 appears periodically in the time domain in the form of SS burst set, as shown in fig. 4.

The number of actually transmitted beams of each cell is determined by the configuration of 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 (maximum beam number)
		up to 3(2.4)GHz	4
3(2.4)GHz—6GHz	8
		6GHz—52.6GHz	64

TABLE 1

In radio resource management (Radio Resource Management, RRM) measurements, the measurement signals may be SSB measurements, i.e. SSS signals in SSB or demodulation reference signal (Demodulation Reference Signal, DMRS) signals of 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 SS burst set period. So in order for the terminal device to save energy during the measurement process, the network side configures the terminal device with SMTC, and the terminal device only needs to perform measurement within the SMTC window, 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 actually measured SSB transmission location, e.g. the union of the SSB actually transmitted locations of all measurement cells, e.g. at 3-6GHz, the bit map (bitmap) is indicated: 10100110, which is used to inform the terminal device to make measurements only on SSBs with SSB index 0,2,5,6 in the candidate locations of 8 SSBs. The configuration of the bit map is shown in table 2 below:

TABLE 2

For the idle (idle) state, the measurement configuration in the inactive (inactive) state comes from the network system broadcast configuration. These configuration information are configured with cell granularity (per cell), such as a list of measured inter-frequency points, as shown in table 3 below:

TABLE 3 Table 3

The measurement configuration for the connection state is configured by radio resource control (Radio Resource Control, RRC) dedicated signaling.

Currently, only one SMTC is configured for each frequency layer in a system broadcast. But considering that the cell deployed by the current frequency layer has a macro cell (mainly meeting the coverage requirement) and a small cell (mainly meeting the capacity requirement). For small cells that meet capacity requirements, the period of SSB is typically longer (e.g., SSB period is 160 ms), while for macro cells that meet coverage requirements, SSB is typically shorter (e.g., SSB period is 20 ms). If only one SMTC is configured, the period of the SMTC window is typically configured to be 160ms. Since the 160ms SMTC window ensures that SSBs of all cells can be measured. However, such SMTC configurations may cause cell reselection delays for cells with shorter SSB periods, which may affect traffic performance. An additional SMTC configuration is introduced in R16 to meet the cell measurement requirements of different SSB periods. The newly introduced SMTC configuration is applicable to cells with longer SSB periods and the original SMTC configuration is applicable to cells with shorter SSB periods. Alternatively, the newly introduced SMTC configuration is used to determine a SMTC window for a longer period, and the original SMTC configuration is used to determine a SMTC window for a shorter period.

Only one SSB-tomecure (abbreviated SSB measurement configuration) is currently configured on the standard for indicating the index set of SSBs measured within the SMCT window. But currently it is not clear how to use SSB measurement configurations for two SMTC configurations. On the other hand, if two SMTC configurations use the same SSB measurement configuration, the terminal device is caused to measure an unnecessary SSB, resulting in an increase in power consumption. For the terminal equipment in the connection state, the network side also configures two SMTC configurations, and also configures one SSB-tomecure, and the above problems also exist in the terminal equipment in the connection state. In order to determine which SSB measurement configuration each of the two SMTC configurations uses, the following technical solutions of the embodiments of the present application are presented.

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

step 601: the method comprises the steps that terminal equipment receives first configuration information sent by network equipment, wherein the first configuration information comprises configuration of at least one frequency layer; each of the at least one frequency layer comprises a first SMTC configuration and a second SMTC configuration in its configuration; wherein the configuration of each of the at least one frequency layer further comprises one or two SSB measurement configurations, the one or two SSB measurement configurations being used to determine a set of SSBs that need to be measured within a first SMTC window and a set of SSBs that need to be measured within a second SMTC window.

In the embodiment of the application, the network equipment sends the first configuration information to the terminal equipment, and correspondingly, the terminal equipment receives the first configuration information sent by the network equipment. Further optionally, the network device may be a base station, such as a gNB.

In the embodiment of the application, the terminal equipment can be in an idle state or an inactive state or a connection state. The following describes the technical scheme of the embodiment of the present application in detail with reference to different RRC states.

The terminal equipment is in an idle state or a non-activated state.

The network equipment sends a system broadcast message to the terminal equipment, and correspondingly, the terminal equipment receives the system broadcast message sent by the network equipment, wherein the system broadcast message carries the first configuration information. Further optionally, the system broadcast message includes at least one of: SIB2, SIB4.

Here, the first configuration information is a configuration for an idle state or an inactive state. The first configuration information includes a configuration of at least one frequency layer, where each of the at least one frequency layer includes a first SMTC configuration and a second SMTC configuration.

In the embodiment of the present application, the first SMTC configuration is used for determining a first SMTC window, and specifically, the first SMTC configuration may include period information of the first SMTC window, size information of the first SMTC window, offset information of the first SMTC window, and the like. Similarly, the second SMTC configuration is configured to determine a second SMTC window, and in particular, the second SMTC configuration may include period information of the second SMTC window, size information of the second SMTC window, offset information of the second SMTC window, and the like.

In actual implementation, the first SMTC configuration is an original SMTC configuration, and the second SMTC configuration is an additional SMTC configuration that is newly introduced. Optionally, the first SMTC configuration is adapted for cells having a longer SSB period and the second SMTC configuration is adapted for cells having a shorter SSB period. Specifically, cells are grouped according to SSB periods, cells with longer SSB periods are grouped into one group, and cells with shorter SSB periods are grouped into another group. Here, the longer SSB period and the shorter SSB period may be divided by one threshold, for example, division in which the SSB period is greater than the threshold is divided into longer SSB periods, and division in which the SSB period is less than or equal to the threshold is divided into shorter SSB periods.

In an alternative embodiment, the first SMTC configuration carries first indication information, where the first indication information is used to indicate a first cell list for performing SSB measurements using a first SMTC window; and/or, the second SMTC configuration carries second indication information, said second indication information being used for indicating a second cell list for performing SSB measurements using a second SMTC window.

For example: the first cell list includes identification information of one or more cells having a longer SSB period, and the second cell list includes identification information of one or more cells having a shorter SSB period. Wherein one or more cells with longer SSB periods perform SSB measurements using a first SMTC window and one or more cells with shorter SSB periods perform SSB measurements using a second SMTC window.

In the embodiment of the present application, the SSB measurement configuration includes a first bitmap, each bit in the first bitmap corresponds to one SSB index, and the value of the bit is used to indicate whether the SSB indicated by the SSB index corresponding to the bit needs to be measured. For example, the first bit map is 10100110, which is used to inform the terminal device to measure only SSBs with SSB index 0,2,5,6 in candidate locations of 8 SSBs.

How the terminal device determines the SSB set to be measured is described below in connection with two cases, one SSB measurement configuration and two SSB measurement configurations, respectively.

1) In the case that one SSB measurement configuration is included in the configuration of each of the at least one frequency layer, the first SSB measurement configuration is used by the terminal device to determine the set of SSBs that need to be measured within the first SMTC window and the second SMTC window.

If the terminal device performs SSB measurement in a first SMTC window, the terminal device determines an SSB set to be measured in the first SMTC window based on the one SSB measurement configuration; if the terminal device performs SSB measurements within a second SMTC window, the terminal device determines a set of SSBs that need to be measured within the second SMTC window based on the one SSB measurement configuration.

In particular implementations, in SIB2 and/or SIB4, two SMTC configurations (i.e., a first SMTC configuration and a second SMTC configuration) are configured in the configuration of each frequency layer. Each of the two SMTC configurations is configured with a cell list that specifies cells that can be measured using the SMTC window corresponding to that SMTC configuration. SIB2 includes an intra-frequency configuration (intra-frequency configuration), and SIB4 includes an inter-frequency configuration (inter-frequency configuration). Further, when one SSB-tomecure is configured in the configuration of each frequency layer in SIB2 and/or SIB4, the terminal device uses SSB-tomecure to constrain the SSB index set of measurement when performing measurement in two SMTC windows, respectively, and configuration information of SSB-tomecure is shown in table 4 below.

TABLE 4 Table 4

2) In the case that two SSB measurement configurations are included in the configuration of each of the at least one frequency layer, the two SSB measurement configurations include a first SSB measurement configuration and a second SSB measurement configuration, the first SSB measurement configuration being used by the terminal device to determine a set of SSBs that need to be measured within a first SMTC window; the second SSB measurement configuration is for the terminal device to determine a set of SSBs that need to be measured within a second SMTC window.

If the terminal device performs SSB measurement in a first SMTC window, the terminal device determines an SSB set to be measured in the first SMTC window based on a first SSB measurement configuration; if the terminal device performs SSB measurement in a second SMTC window, the terminal device determines an SSB set to be measured in the second SMTC window based on a second SSB measurement configuration; wherein the two SSB measurement configurations include the first SSB measurement configuration and the second SSB measurement configuration.

In particular implementations, in SIB2 and/or SIB4, two SMTC configurations (i.e., a first SMTC configuration and a second SMTC configuration) are configured in the configuration of each frequency layer. Each of the two SMTC configurations is configured with a cell list that specifies cells that can be measured using the SMTC window corresponding to that SMTC configuration. SIB2 includes an intra-frequency configuration (intra-frequency configuration), and SIB4 includes an inter-frequency configuration (inter-frequency configuration). Further, in addition to configuring one SSB-tomeure, one SSB-tomeur (e.g., SSB-tomeur 2) is additionally configured in the configuration of each frequency layer in SIB2 and/or SIB4, the terminal device uses the SSB-tomeure corresponding to each to restrict the SSB index set of measurement when performing measurement in two SMTC windows respectively. The SSB-measure IE (for carrying the first SSB measurement configuration) is used to restrict the SSB index set of measurements, for example when the terminal device performs measurements within the SMTC window of the SMTC IE (for carrying the first SMTC configuration) configuration. The SSB-tomecure 2 IE (for carrying the second SSB measurement configuration) is used to constrain the SSB index set of measurements when the terminal device performs measurements within the SMTC window of the SMTC2-LP IE (for carrying the second SMTC configuration) configuration. Further, if SSB-tomecure 2 is not configured, the terminal device uses SSB-tomecure to restrict the SSB set that performs measurements in SMTC window configured by the SMTC2-LP IE. If the SSB-ToMessaure is also not configured, the terminal device measures all SSBs, and specific configuration information is shown in Table 5 below.

TABLE 5

The terminal equipment is in an activated state

The network equipment sends an RRC message to the terminal equipment, and correspondingly, the terminal equipment receives the RRC message sent by the network equipment, wherein the RRC message carries the first configuration information.

Here, the first configuration information is a configuration for an active state. The first configuration information includes a configuration of at least one frequency layer, where each of the at least one frequency layer includes a first SMTC configuration and a second SMTC configuration.

In particular, in the measurement configuration of the connection state, two SMTC configurations (i.e., a first SMTC configuration and a second SMTC configuration) are configured in the configuration of each measurement object. Each of the two SMTC configurations is configured with a cell list that specifies cells that can be measured using the SMTC window corresponding to that SMTC configuration. Further, when an SSB signal is configured in the configuration of the measurement object and one SSB-ToMeasure is configured in the configuration of the SSB signal, when the terminal device performs measurement in two SMTC windows respectively, the SSB-ToMeasure is used to restrict the SSB index set of the measurement, and configuration information of the SSB-ToMeasure is shown in the following tables 6 and 7.

/>

TABLE 6

TABLE 7

In particular, in the measurement configuration of the connection state, two SMTC configurations (i.e., a first SMTC configuration and a second SMTC configuration) are configured in the configuration of each measurement object. Each of the two SMTC configurations is configured with a cell list that specifies cells that can be measured using the SMTC window corresponding to that SMTC configuration. Further, when the SSB signal is configured in the configuration of the measurement object and two SSB-tomeasures (i.e., SSB-tomeasures and SSB-tomeasures 2) are configured in the configuration of the SSB signal, when the terminal device performs measurement in two SMTC windows, respectively, the terminal device uses the SSB-tomeasures corresponding to each to restrict the SSB index set of the measurement. The SSB-measure IE (for carrying the first SSB measurement configuration) is used to restrict the SSB index set of measurements, for example when the terminal device performs measurements within the SMTC window of the SMTC1 IE (for carrying the first SMTC configuration) configuration. The SSB-tomecure 2 IE (for carrying the second SSB measurement configuration) is used to constrain the SSB index set of measurements when the terminal device performs measurements within the SMTC window of the SMTC2 IE (for carrying the second SMTC configuration) configuration. Further, if SSB-tomeure 2 is not configured, the terminal device uses SSB-tomeure to restrict SSB sets that perform measurements in SMTC windows configured by the SMTC2 IE. If the SSB-tomecure is not configured either, the terminal device measures all SSBs, and specific configuration information is shown in table 8 below.

TABLE 8

By the technical scheme of the embodiment of the application, the corresponding ssb-ToMessaure is configured for each SMTC window, so that the purpose of saving power of terminal equipment is achieved. On the other hand, for different SSB-tomecure configuration cases (for example, SSB-tomecure is not configured, or 1 SSB-tomecure is configured, or 2 SSB-tomecure is configured), SSBs that need to be measured in two SMTC windows are respectively defined.
