In order to facilitate understanding of the technical solutions of the embodiments of the present application, the relevant technologies of the embodiments of the present application are described below. The following related technologies can be optionally combined with the technical solutions of the embodiments of the present application, and they all belong to the embodiments of the present application. protected range.

low capability terminal equipment

The NR system is mainly designed to support enhanced mobile ultra-broadband (eMBB) services. Its main technology is to meet the needs of high speed, high spectrum efficiency, and large bandwidth. In fact, in addition to eMBB services, there are other types of services that have different requirements from eMBB services in terms of speed, bandwidth, power consumption, cost, etc., such as massive machine-type communications (mMTC). ) business, the typical characteristics of mMTC business include: high connection density, small data volume, insensitivity to delay, low cost and long service life of the module. The terminal equipment that supports these services has lower capabilities than the terminal equipment that supports eMBB services, such as the supported bandwidth is reduced, the processing time is relaxed, the number of antennas is reduced, the maximum modulation order is relaxed, etc., the capabilities of the terminal equipment that support these services can be reduced. Terminal devices are referred to as low-capability terminal devices (RedCap UE), such as sensors, video surveillance equipment, wearable devices, etc.

In order for the NR system to better support other types of services besides eMBB services, the NR system needs to be optimized for these services and the terminal equipment that supports these services.

The NR system supports broadband transmission. In the FR1 frequency band, the maximum bandwidth of a single carrier can reach 100MHz, and in the FR2 frequency band, the maximum bandwidth of a single carrier can reach 400MHz. Broadband transmission can significantly increase the peak rate supported by terminal equipment and shorten data transmission delays, but it also brings about problems such as increased terminal equipment cost and significantly increased power consumption. For low-capacity terminal equipment, it is more necessary to consider the cost and power consumption of the terminal equipment. For this reason, the relevant technology defines that in the FR1 frequency band, the maximum bandwidth supported by low-capability terminal equipment is reduced to 20MHz. In the FR2 frequency band, the maximum bandwidth supported by low-capability terminal equipment is reduced to 20MHz. The maximum supported bandwidth is reduced to 100MHz. In order to further reduce the cost and power consumption of low-capability terminal equipment, related technologies consider further reducing the maximum bandwidth supported by low-capability terminal equipment to 5MHz in the FR1 frequency band.

RRM measurement

For wireless mobile communication systems, accurate measurement of cell quality and beam quality is the basis for effective implementation of wireless resource management and mobility management. For 5G NR, two major types of reference signals are currently considered as measurement reference signals, namely synchronization signal and physical broadcast channel block (Synchronization Signal/PBCH Block, SSB) and channel state information reference signal (Channel-state information, CSI-RS).

For SSB-based measurement, the network configures SSB measurement resources to the terminal device through high-level signaling, so that the terminal device can perform corresponding measurement operations. For example, the SSB measurement configuration includes: SSB frequency point, SSB subcarrier spacing, SSB measurement time configuration (SSB Measurement Timing Configuration, SMTC) configuration, reference signal configuration, etc. Among them, the SSB frequency point is the center frequency point of the SSB to be measured. The SSB subcarrier spacing is the subcarrier spacing of the SSB to be measured. SMTC configuration is the time domain resource configuration information of SSB measurement, which is mainly used to configure a set of measurement time windows (called SMTC windows) based on SSB measurement. The SSB configuration may further include an SSB to be measured indication (ssb-ToMeasure), etc. The SSB to be measured indication uses a bitmap to indicate the location information of the actually transmitted SSB in the SSB burst set. The terminal device can clearly know which SSB is to be measured through the SSB to be measured indication. The SSB candidate locations actually send SSB, and which SSB candidate locations do not send SSB. The terminal device does not need to perform measurements at locations where SSB is not sent, thereby achieving energy saving for the terminal device.

SSB includes Primary Synchronization Signal (PSS), Secondary Synchronization Signal (SSS) and Physical Broadcast Channel (PBCH). The frequency domain resources of SSB occupy 20 RBs. In the FR1 frequency band, the sub-carrier spacing of SSB is 15kHz or 30kHz, and in the FR2 frequency band, the sub-carrier spacing of SSB is 60kHz or 120kHz. The bandwidth corresponding to the frequency domain resources of SSB is related to the number of RBs occupied by it and the subcarrier spacing. Specifically, the bandwidth corresponding to the frequency domain resources of SSB = the number of RBs occupied by the frequency domain resources of SSB × the subcarrier spacing of SSB × 12. For example: Taking the subcarrier spacing of SSB as an example, the bandwidth corresponding to the frequency domain resources of SSB is 3.6MHz. Another example: Taking the subcarrier spacing of SSB as an example, the bandwidth corresponding to the frequency domain resources of SSB is 7.2MHz.

SSBs appear periodically in the time domain in the form of SSB burst sets, and each SSB burst set can contain one or more SSBs. The terminal device performs SSB measurements within the SMTC window, which appears periodically in the time domain. For example, as shown in Figure 2, each SSB burst set contains 8 SSBs, and the SSB transmission period is the time interval between two adjacent SSBs with the same SSB index. The SSB transmission period, SMTC window size, and SMTC window period are all adjustable.

For CSI-RS-based measurements, the network configures one or more CSI-RS resources through higher-layer signaling for terminal equipment to perform measurements. Specifically, first, in units of cells, high-layer signaling configures cell-level CSI-RS configuration parameters, such as cell ID, cell measurement bandwidth, measurement density, measurement resource list and other information. In addition, since each cell can be configured with multiple CSI-RS resources, the high-level signaling further configures the configuration information of each CSI-RS resource level, such as the CSI-RS index of the CSI-RS resource and the time occupied by the CSI-RS resource. domain and/or frequency domain resource information, sequence generation methods, etc.

Exemplarily, the configuration information of CSI-RS used for RRM measurement may include the content shown in Table 1 below:

Table 1

Among them, subcarrierSpacing is used to configure the subcarrier spacing of CSI-RS. nrofPRBs is used to configure the number of RBs occupied by CSI-RS frequency domain resources. startPRB is used to configure the starting RB occupied by the frequency domain resources of CSI-RS. In the FR1 frequency band, the candidate values for the subcarrier spacing of the CSI-RS are: 15kHz, 30kHz, and 60kHz, and the candidate values for the number of RBs occupied by the frequency domain resources of the CSI-RS are: 24, 48, 96, 192, 264. In the FR2 frequency band, the candidate values for the subcarrier spacing of the CSI-RS are: 60kHz and 120kHz, and the candidate values for the number of RBs occupied by the frequency domain resources of the CSI-RS are: 24, 48, 96, 192, and 264. The bandwidth corresponding to the frequency domain resources of CSI-RS is related to the number of RBs occupied by it and the subcarrier spacing. Specifically, the bandwidth corresponding to the frequency domain resources of CSI-RS = the number of RBs occupied by the frequency domain resources of CSI-RS × CSI- The subcarrier spacing of RS is ×12. For example: assuming that the number of RBs occupied by the CSI-RS frequency domain resources is 24 and the subcarrier spacing of the CSI-RS is 15 kHz, the corresponding bandwidth of the CSI-RS frequency domain resources is 4.32 MHz.

In the above solution, the frequency range corresponding to the FR1 frequency band can be from 410MHz to 7.125GHz, and the frequency range corresponding to the FR2 frequency band can be from 24.25GHz to 52.6GHz. Of course, the frequency ranges corresponding to the FR1 frequency band and the FR2 frequency band can also be adjusted.

For low-capacity terminal devices, the maximum bandwidth supported is very limited. Using the current configuration method of measuring reference signals may cause the bandwidth of the reference signal to exceed the maximum bandwidth supported by low-capability terminal equipment, causing low-capacity terminal equipment to be unable to implement RRM measurements.

To this end, the following technical solutions of the embodiments of the present application are proposed. In the technical solution of the embodiment of the present application, the configuration of the reference signal (hereinafter referred to as the measurement reference signal) used for RRM measurement takes into account the limitations of the bandwidth capability of the terminal equipment, so that the bandwidth corresponding to the frequency domain resource of the measurement reference signal is less than or equal to the terminal equipment. The maximum bandwidth supported or the bandwidth corresponding to the BWP that the terminal device works on.

In order to facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The above related technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the protection scope of the embodiments of the present application. The embodiments of this application include at least part of the following content.

Application example one

For CSI-RS-based RRM measurement, the CSI-RS configured by the network device may be the CSI-RS of the current cell or the CSI-RS of the adjacent cell. Whether it is the CSI-RS of this cell or the CSI-RS of neighboring cells, the network equipment needs to consider the maximum bandwidth supported by the terminal equipment in this cell when configuring the number of RBs and subcarrier spacing corresponding to the frequency domain resources of the CSI-RS. capabilities or the bandwidth of the BWP working in this cell, the configured number of RBs and subcarrier spacing need to meet the following conditions: the bandwidth corresponding to the CSI-RS frequency domain resources determined based on the number of RBs and subcarrier spacing is less than or equal to the terminal equipment in this cell. The maximum bandwidth supported by the cell or the bandwidth of the BWP working in this cell. In particular, for the situation where the CSI-RS configured by the network device is the CSI-RS of the neighboring cell, the terminal device does not access the neighboring cell, nor is it configured with the BWP of the neighboring cell, but is configured with CSI-RS resources. The corresponding number of RBs and subcarrier spacing. Here, when configuring the subcarrier spacing corresponding to the CSI-RS resource, you need to consider whether the neighboring cell supports the subcarrier spacing. When the network device configures the subcarrier spacing of the CSI-RS resource, in addition to the need In addition to meeting the above conditions, neighboring cells also need to support subcarrier spacing.

For example, the network device configures the number of RBs corresponding to the frequency domain resources of the CSI-RS through the nrofPRBs parameter, and configures the subcarrier spacing corresponding to the frequency domain resources of the CSI-RS through the subcarrierSpacing parameter. The candidate values of nrofPRBs and/or the candidate values of subcarrierSpacing are updated relative to the existing technology and are used to meet the RRM measurement of low-capability terminals.

Taking the maximum supported bandwidth of 5MHz for low-capability terminals as an example, the bandwidth corresponding to the frequency domain resource of CSI-RS configured by the network device is less than or equal to 5MHz. In the FR1 frequency band, candidate values for subcarrierSpacing include: 15kHz, 30kHz, and 60kHz, and candidate values for nrofPRBs include: 24, 12, and 4. The combined value of the number of RBs and subcarrier spacing includes the following options: {24 RBs, 15kHz}, {12 RBs, 15kHz}, {4 RBs, 15kHz}, {12 RBs, 30kHz}, {4 RBs , 30kHz}, {4 RB, 60kHz}. It can be seen that the number of combined value options has been greatly increased, which is beneficial to the implementation of CSI-RS measurement.

As an example: The candidate values of the modified nrofPRBs are shown in Table 2 below, including three values: size4, size12, and size24.

Table 2

Taking the maximum supported bandwidth of 20MHz for a low-capacity terminal as an example, the bandwidth corresponding to the frequency domain resource of CSI-RS configured by the network device is less than or equal to 20MHz. In the FR2 frequency band, candidate values for subcarrierSpacing include: 60kHz, 120kHz, and candidate values for nrofPRBs include: 24, 12, and 4. The combined value of the number of RBs and subcarrier spacing includes the following options: {24 RBs, 60kHz}, {12 RBs, 60kHz}, {4 RBs, 60kHz}, {12 RBs, 120kHz}, {4 RBs ,120kHz}.

Application example two

For RRM measurements based on SSB, when configuring the subcarrier spacing corresponding to the SSB frequency domain resources, the network device needs to consider the maximum bandwidth capability supported by the terminal device or the bandwidth of the working BWP. The configured subcarrier spacing needs to meet the following conditions: The bandwidth corresponding to the frequency domain resources of the SSB determined based on the number of RBs and the subcarrier spacing is less than or equal to the maximum bandwidth supported by the terminal device or the bandwidth of the working BWP. The subcarrier spacing corresponding to the frequency domain resources of SSB can be independently configured or preset. The number of RBs corresponding to the frequency domain resources of SSB is fixed to 20.

For example, the network device configures the subcarrier spacing corresponding to the frequency domain resource of the SSB through the ssbSubcarrierSpacing parameter. The candidate value of ssbSubcarrierSpacing is used to meet the RRM measurement of low-capability terminals.

Taking the maximum supported bandwidth of 5MHz for low-capability terminals as an example, the bandwidth corresponding to the frequency domain resource of SSB configured by the network device is less than or equal to 5MHz. In the FR1 frequency band, the number of RBs corresponding to the SSB frequency domain resources is fixed to 20, and the candidate value of the subcarrier spacing corresponding to the SSB frequency domain resources is 15 kHz. It should be noted that ssbSubcarrierSpacing can take the default value of 15kHz, or this information indication is not required.

Taking the maximum supported bandwidth of 20MHz for low-capability terminals as an example, the bandwidth corresponding to the SSB frequency domain resources configured by the network equipment is less than or equal to 20MHz. In the FR2 frequency band, the number of RBs corresponding to the frequency domain resources of SSB is fixed to 20, and the candidate value of the subcarrier spacing corresponding to the frequency domain resources of SSB is 60kHz. It should be noted that ssbSubcarrierSpacing can take the default value of 60kHz, or this information indication is not required.

As an example: the configuration information of ssbSubcarrierSpacing is shown in Table 3 below.

table 3

The maximum bandwidth or the bandwidth corresponding to the BWP that the terminal device works on. In this way, the RRM measurement of the measurement reference signal by the terminal device can be successfully implemented.
