Technical field

The embodiments of this application relate to the field of communications. In particular, it relates to a communication method, device and system.

Background technique

During the signal transmission process, there are generally out-of-band emissions and spurious emissions in component carriers (CCs), especially on CCs that are closely spaced in the frequency domain. External leakage produces strong intraband interference, and communication equipment may fail to receive signals on the CC. In order to avoid such interference, users receiving signals on adjacent channels can be spatially isolated through scheduling, which requires measuring the distance and path loss (PL) between users. The current new radio (NR) protocol defines a measurement mechanism for interference between users, which can be used to calculate path loss. However, during the interference measurement process, the receiving user of the sounding reference symbol (SRS) needs to measure all the sending users of SRS, which will cause large power consumption and signaling overhead and affect the measurement efficiency.

Therefore, how to reduce the power consumption and signaling overhead of interference measurement and improve measurement efficiency is an issue that needs to be solved urgently.

In order to facilitate understanding of the solutions of the embodiments of the present application, relevant concepts are explained.

1. Channel status information report configuration (CSI-ReportConfig): Mainly used to configure parameters related to channel status reporting, such as reporting type, reported measurement indicators, etc. Among them, the reporting configuration identification (reportConfigId) is the identification (identity, Id) number of the CSI-ReportConfig, used to mark the CSI-ReportConfig; the channel measurement resources (resourcesForChannelMeasurement) are used to configure the channel state information-reference signal for channel measurement. (CSI-Reference Signal, CSI-RS) resources, which are associated to resource configuration through CSI-ResourceConfigId; interference measurement resources (CSI-IM-RessourcesForInterference), which configure CSI-RS resources for interference measurement, are associated to CSI-ResourceConfigId. Resource allocation.

Optionally, parameters related to CSI reporting can include CSI reporting type (reportConfigType), CSI reporting quantity (reportQuantity), etc. CSI reporting types can be divided into periodic, semi-persistent and aperiodic reporting; network devices can report through different Report quantity configuration allows terminal devices to report different CSI, including CSI-RS resource indicator (CRI), rank indicator (RI), and pre-coding matrix indicator (Pre-coding Matrix Indicator, PMI) , Channel Quality Indicator (Channel Quantity Indicator, CQI), etc.

2. Channel state information resource configuration (CSI-ResourceConfig): used to configure resource-related information for CSI measurement. It may include reporting resource identification (CSI-ResourceConfigId) and/or resource combination queue (CSI-RS-ResourceSetList), etc. The CSI-ResourceConfigId is used to mark the csi-ResourceConfig; the CSI-RS-ResourceSetList may include a resource set used for channel measurement and a resource set used for interference measurement.

3. Channel state information (CSI): The signal passes from the transmitter to the receiver through the wireless channel. During the receiving process, fading may occur due to scattering, reflection, and attenuation of energy with distance. CSI is used to characterize wireless channels and can include CQI, PMI, CRI, synchronization signal and physical broadcast channel block (SSB resource indicator, SSBRI), layer indicator (synchronization signal and physical broadcast channel block, SSB), and layer indicator. , LI), RI, at least one of L1-reference signal received power (RSRP) and L1-signal to interference plus noise ratio (SINR). CSI can be sent by the terminal device to the network device through the physical uplink control channel (PUCCH) or the physical uplink share channel (PUSCH).

4. CSI report: The CSI report is sent by the terminal to the base station and is used by the network device to learn the channel status when it sends downlink information to the terminal device. One CSI report is used to instruct the terminal device to feedback one CSI. Different CSIs can correspond to different frequency bands, different transmission assumptions or different reporting modes.

Generally speaking, a CSI report can be associated with one reference signal resource for channel measurement and one or more reference signal resources for interference measurement. A CSI report corresponds to a transmission resource, that is, the time-frequency resource used by the terminal device to send the CSI.

5. Reference signal: It is a known signal provided by the transmitter to the receiver for channel estimation or channel detection. In embodiments of the present application, the reference signal can be used for channel measurement, interference measurement, etc., such as measuring parameters such as reference signal receiving quality (RSRQ), SINR, CQI, and/or PMI.

6. Reference signal resources: including at least one of time-frequency resources, antenna ports, power resources, scrambling codes and other resources of the reference signal. The network device may send a reference signal to the terminal device based on the reference signal resource, and accordingly, the terminal device may receive the reference signal based on the reference signal resource.

The reference signal involved in the embodiment of this application may include one or more of the following reference signals: channel state information reference signal (channel state information-reference signal, CSI-RS), SSB or sounding reference signal (sounding reference signal, SRS) . Correspondingly, the reference signal resources may include CSI-RS resources, SSB resources or SRS resources. In some cases, SSB can also refer to SSB resources.

7. Complementary time-division duplex mode (time-division duplex, TDD) (complementary TDD) frame structure: two sets of downlink (D) and uplink (U) subframes with complementary frame structures, such as a section of D:U=4 :1, a section is D:U=1:4, and the complementary frame structure enables U and D resources to be called on each orthogonal frequency division multiplexing symbol (OS).

8.CC: Carrier unit used for carrier aggregation (CA). For example, the maximum bandwidth of each CC can be 20MHz. Each CC can correspond to an independent cell (cell), and each CC can have a corresponding index. For example, the primary CC index is fixed at 0, and the index of the secondary CC of each UE can be controlled through the UE-specific radio resource ( radio resource control, RRC) signaling configuration. The CCs aggregated by a certain UE usually come from the same eNodeB.

During the signal transmission process, there will generally be out-of-band leakage and spurious leakage in CCs. Especially on CCs with close frequency domain spacing, strong adjacent-channel interference will be generated due to out-of-band leakage. Signals received on this CC may fail. The following takes an industrial scenario as an example to describe this. With the development of NR, the expansion of industrial scenarios and the evolution of needs, indoor deployment in factories needs to meet the needs of mixed services. Hybrid services currently include two categories: uplink centric broadband communication (UCBC), such as industrial camera-related services; ultra-reliable and ultra-low latency communications (URLLC), such as robotic arm grasping Hand control related business. When deploying these two types of scenarios in the same area, due to the scarcity of spectrum, it may be necessary to configure adjacent channels within one bandwidth (band). For UCBC services, uplink services account for a relatively high proportion, so more uplink subframe resources are required in the frame structure (such as D:U=1:4 or 3:7), where D represents downlink and U represents uplink. In addition, since URLLC needs to ensure service transmission delay, it needs to adopt the ultra-wideband complementary time division duplex mode (intra band complementary TDD) frame structure. An example of a frame structure is shown in Figure 2. In the figure, CC1, CC2 and CC4 are occupied by UCBC services, and CC3 and CC5 are configured with intraband complementary TDD to support URLLC services. For this kind of scenario, take the transmission from a UCBC terminal of CC4 as an example. During transmission, in addition to the valid signal within the CC4 bandwidth, the transmitted signal has out-of-band leakage and spurious leakage. Since the frequency domain separation between CC4 and CC5 is very close, the out-of-band leakage generated by CC4 will leak to CC5, causing strong adjacent-channel leakage interference to users who are receiving signals on the D subframe of CC5, thus reducing the SINR of the user. , resulting in the user possibly failing to receive the signal. Since CC3 and CC5 transmit URLLC services, URLLC services have the characteristics of low latency and high reliability. This failure to receive signals will have a serious negative impact on the business.

In order to deal with such interference, UCBC users and URLLC users need to be spatially isolated through scheduling (such as scheduling distant users to transmit at the same time), and the frequency domain needs to be spread out (such as scheduling distant users Transmit on CC4 which is close to CC5, and schedule users who are close to CC1 and CC2 which are far away from CC5 for transmission). In order to achieve this effect, the distance and path loss between scheduled users need to be measured. Among them, the path loss can be calculated through interference measurement. For example, the current NR protocol defines a measurement mechanism for interference between users, and interference measurement can be performed based on cross-link interference SRS (CLI-SRS). Specifically, the cell configures sending users to send measurement signals, and configures receiving users to receive on corresponding time-frequency code resources. By receiving user measurements, the SRS-RSRP of the SRS sequence sent on this bandwidth is obtained, or the received signal strength indication (CLI-RSSI) of this measurement bandwidth. The measured SRS-RSRP and CLI-RSSI are reported by the receiving user according to the cell's reporting configuration. The cell then obtains the CLI-SRS transmit power of the sending user and the SRS-RSRP and CLI-RSSI reported by the receiving user. Calculate the path loss between the sending user and the receiving user. In the ultra-bandwidth (intraBand) scenario, the number of large-capacity users is 100+, and the number of URLLC users reaches 900. The interaction process between the cell, sending users (URLLC user group) and receiving users (UCBC user group) can be shown in Figure 3:

Step 301: The URLLC cell configures SRS resources to the URLLC user group.

Step 302: The URLLC cell sends the SRS resource location information to the UCBC cell.

Step 303: The UCBC cell configures the SRS-RSRP measurement configuration and reporting configuration for URLLC users 1 to 32 to the UCBC users.

Step 304: URLLC users 1 to 32 send SRS to UCBC users.

Step 305: The UCBC user sends the measurement results for URLLC users 1 to 32 to the UCBC cell.

Step 306: The UCBC cell configures the SRS-RSRP measurement configuration and reporting configuration for URLLC users 33 to 64 to the UCBC users.

Step 307: URLLC users 33 to 64 send SRS to UCBC users.

Step 308: The UCBC user sends the measurement results for URLLC users 33 to 64 to the UCBC cell.

By analogy, the UCBC user sends the measurement results for URLLC users 869 to 900 to the UCBC cell.

The cell configuration resources, configuration measurement configuration and reporting configuration in the above steps can be understood as the basis for managing the cell. Station configures resources, configures measurement configuration and reporting configuration. Among them, the measurement configuration can indicate the time starting position and duration of this measurement, the frequency domain starting position and duration, the periodicity/triggering of the measurement, and other characteristics. When the SRS on the transmitting side is configured for periodic transmission, the corresponding measurement configuration is configured according to the corresponding period and offset. The reporting configuration is divided into two types of measurement quantities: SRS-RSRP and CLI-RSSI. The configured reporting method is separate (choice) reporting. The user reports the measurement results that are higher than the threshold. The CLI-RSSI in the reporting content includes the corresponding RSSI. The identification of the measurement resource (rssi-ResourceId-r16). SRS-RSRP contains the identification of the measurement resource (SRS-ResourceId) corresponding to the RSRP. These identifications are consistent with the resource identification configured in the measurement configuration. The network device can Determine which measurement resource the measurement result is based on the identification. Reporting configurations can be divided into two categories: periodic reporting and event reporting. When the user under test performs measurements and adopts the periodic reporting configuration, the measurement results between the last report and the current report are reported. The measurement results all correspond to the SRS/RSSI-ResourceId of a location; when the user under test performs measurements, the event is used When reporting the configuration, the report is triggered when the user under test has an event that satisfies i1 on the measured resource, and the reported content carries the SRS/RSSI-ResourceId.

In the above scenario, each UCBC user needs to measure 900 URLLC users. Assuming that only one antenna of the URLLC (corresponding to one time-frequency comb resource) is measured, 900 sets of measurement configurations need to be issued. The current protocol only supports 32 RSRPs. /The length of 64 RSSIs (corresponding to the UE’s measurement capability definition). These measurements can be delivered in a sequence in an RRC signaling. Each sequence can indicate up to 32 RSRP measurements or 64 RSSIs. Measurement related configuration. For each UCBC user, if the path loss between UEs needs to be measured based on RSRP, the corresponding measurement signaling carries the measurement configuration of 32 users in a single piece, and approximately 29 pieces of signaling need to be received continuously. Assume that URLLC users send SRS in a 5ms cycle. After the measurement configuration and reporting configuration of UCBC users are issued, the SRS is measured and reported within 2.5ms on average. The total time of a measurement round is: 29*2.5≈75ms. There is a large Issue overhead and report overhead. Moreover, the current measurement configuration only indicates a certain starting position in the frequency domain. When there are many users to be measured, each user needs to configure the measurement configuration of all users on the opposite side in a time-sharing manner, considering that the user's measurement capabilities are limited. , it also requires time-sharing and user-based delivery of measurement configuration, resulting in complex measurement configuration and high signaling and reporting overhead.

In order to reduce the measurement complexity and improve the measurement efficiency, an embodiment of the present application proposes a communication method, as shown in Figure 4. The method may include the following steps:

Step 401: The first network device sends the first measurement configuration information and the second measurement configuration information to the first terminal device. Correspondingly, the first terminal device receives the first measurement configuration information and the second measurement configuration information.

The first measurement configuration information may be used to measure cross-link interference received signal strength indication CLI-RSSI of the first resource. For example, the first measurement configuration information may include information of the first resource. For example, the first resource The information may be the starting position and length of the first resource in the frequency domain, or the information of the first resource may be the starting position and ending position of the first resource in the frequency domain. The first measurement information may also include the starting position and duration of this CLI-RSSI measurement in the time domain, or the first measurement information may include the starting position and duration of this CLI-RSSI measurement in the time domain. The end position, in other words, the first measurement information may include the time of this CLI-RSSI measurement. The first measurement information may also include that this CLI-RSSI measurement is a periodic measurement, or that this CLI-RSSI measurement is an event measurement.

The second measurement configuration information may be used to measure the sounding reference symbol reference signal received power SRS-RSRP of the second resource. For example, the second measurement configuration information may include the information of the second resource. For example, the information of the second resource may be The starting position and length of the second resource in the frequency domain, or the information about the second resource may be the second resource The starting and ending positions in the frequency domain. The second measurement information may also include the starting position and duration of this SRS-RSRP measurement in the time domain, or the second measurement information may include the starting position and duration of this SRS-RSRP measurement in the time domain. The end position, in other words, the second measurement information may include the time of this SRS-RSRP measurement. The second measurement information may also include that this SRS-RSRP measurement is a periodic measurement, or that this SRS-RSRP measurement is a triggered measurement.

The above-mentioned second resource and the first resource may be the same, or the second resource may be a part of the first resource.

Among them, the first resource and the second resource are the same, which can be understood as the time-frequency position of the first resource and the time-frequency position of the second resource are exactly the same. For example, as shown in (a) in Figure 5, the first resource The resources corresponding to the second resource in the time domain completely overlap, and the resources corresponding to the second resource in the frequency domain also completely overlap.

The second resource is a part of the first resource, which can be understood to mean that the time-frequency position of the second resource is within the time-frequency range of the first resource. For example, the resources corresponding to the second resource in the time domain are within the range of the resources corresponding to the first resource in the time domain, and the resources corresponding to the first resource and the second resource in the frequency domain are the same. For example, as shown in Figure As shown in (b) in 5, the starting position S2 of the resource corresponding to the second resource in the time domain is the same as the starting position S1 of the resource corresponding to the first resource in the time domain, but the second resource is in the time domain. The end position E2 of the corresponding resource is before the end position E1 of the resource corresponding to the first resource in the time domain. For example, the resources corresponding to the second resource in the frequency domain are within the range of the resources corresponding to the first resource in the frequency domain, and the resources corresponding to the second resource and the first resource in the time domain are the same. For example, as shown in Figure As shown in (c) in 5, the starting position S2 of the resource corresponding to the second resource in the frequency domain is after the starting position S1 of the resource corresponding to the first resource in the frequency domain, and the second resource is in the frequency domain. The end position E2 of the corresponding resource is before the end position E1 of the resource corresponding to the first resource in the frequency domain. It should be understood that Figure 5 is only an example and not a limitation. For example, the second resource may be a part of the first resource, or the resource corresponding to the second resource in the frequency domain may be the resource corresponding to the first resource in the frequency domain. within the range, and the resource corresponding to the second resource in the time domain is within the range of the resource corresponding to the first resource in the time domain. This is not limited in the embodiment of the present application. In other words, the second resource is a non-empty subset of the first resource, for example, the time domain resource corresponding to the second resource is a non-empty subset of the time domain resource corresponding to the first resource, and/or, the The frequency domain resources corresponding to the second resource are a non-empty subset of the frequency domain resources corresponding to the first resource.

In one possible implementation, the first resource and the second resource are carriers. In another possible implementation, the first resource and the second resource are partial bandwidth parts (BWP). Or, the first resource is a carrier, and the second resource is a carrier. The resource is BWP, and vice versa. Alternatively, the first resource and the second resource may also be RBG-level or RB-level resources, which is not limited in this embodiment of the present application.

It should be understood that the first network device in step 401 may be the aforementioned radio access network device or core network device, and the first terminal device may be the aforementioned terminal device. For example, the first network device and the first terminal device may be communication devices in an industrial scenario. For example, the first network device may be a network device of a UCBC cell, and the first terminal device may be a terminal device in a UCBC user group. It should also be understood that the first terminal device may include at least one terminal device. For example, the first terminal device may be multiple UCBC terminal devices, which is not limited in this embodiment of the present application.

Step 402: The first terminal device measures the first resource according to the first measurement configuration information and obtains the first CLI-RSSI.

For example, the first terminal device measures the first resource within the measurement time range indicated by the first measurement configuration information, and obtains the first CLI-RSSI.

It should be understood that before the first terminal device makes measurements, the first terminal device also receives the SRS. The SRS may be from the second terminal device. One possible way is that the second terminal device periodically sends SRS to the first terminal device. The period in which the second terminal device sends SRS to the first terminal device may be configured by the second network device, for example, the second The network device sends RRC signaling to the second terminal device, where the RRC signaling includes the SRS transmission cycle and offset. Another possible way is that the second terminal device sends the SRS to the first terminal device in a triggered manner. For example, the second network device notifies the second terminal device to immediately measure the uplink channel information on a certain resource of the cell, or, When the second network device notifies the second terminal device to immediately measure inter-cell/intra-cell interference information on a certain resource, the second terminal device may send an SRS to the first terminal device.

Optionally, when the first CLI-RSSI is greater than or equal to the first threshold, the first terminal device sends the first CLI-RSSI to the first network device, and correspondingly, the first network device receives the first CLI-RSSI.

The first threshold may be indicated by the first network device to the first terminal device. The first threshold may also be predefined, which is not limited in the embodiments of this application.

Step 403: When the first CLI-RSSI is greater than or equal to the first threshold, the first terminal device measures the second resource according to the second measurement configuration information and obtains the first SRS-RSRP.

That is to say, the size of the first CLI-RSSI can be used as a judgment condition for whether the first terminal device measures the second resource. For example, when the first CLI-RSSI is greater than or equal to the first threshold, the first terminal device measures the second resource; when the first CLI-RSSI is less than the first threshold, the first terminal device does not measure the second resource. It should be understood that the first measurement configuration information and/or the second measurement configuration information in step 401 may be sent together or sent separately. For example, the first network device first sends the first measurement configuration information to the first terminal device. When the first terminal device determines that the first CLI-RSSI is greater than or equal to the first threshold, the first terminal device may send indication information to the first network device. The indication information It is used to indicate that the first terminal device needs to measure RSRP, and the first network device sends second measurement configuration information according to the indication information. Alternatively, the first network device may send the first measurement configuration information and the second measurement configuration information to the first terminal device. When the first terminal device determines that it is not necessary to measure RSRP, it may ignore the information about the second resource in the second measurement configuration information. information, that is to say, in this case, the resource indicated by the resource information included in the second measurement configuration information is not used for RSRP measurement. Of course, it can be understood that whether the second resource is used for RSRP measurement is only for this time. The measurement process does not limit the use of the resource.

Optionally, the first network device may send first indication information to the first terminal device, where the first indication information is used to indicate whether to perform SRS-RSRP measurement based on the measurement result of CLI-RSSI measurement. For example, whether to perform the SRS-RSRP measurement may be determined according to the measurement result of the CLI-RSSI measurement according to the identification information of the first resource and the identification information of the second resource. For example, the first indication information may be a coupling of the identification information of the first resource and the identification information of the second resource, such as adding the identification information of the second resource to the identification information of the first resource, or adding the identification information of the second resource to the identification information of the second resource. The identification information of the first resource is added to the identification information. The identification information of the first resource may be a resource identification (Identity document, ID) of the first resource. For example, the ID of the first resource may be CLI-ResourceId. The identification information of the second resource may be the resource ID of the second resource. For example, the ID of the second resource may be SRS-ResourceId. Then, the first indication information may be to add the ID of the second resource (SRS-ResourceId) to the configuration information RSSI-ResourceConfigCLI of the first resource, or to add the ID of the first resource to the configuration information SRS-ResourceConfigCLI of the second resource. (CLI-ResourceId). It can be understood that the first indication information may be carried in the RRC signaling in step 402 and sent to the first terminal device together with the configuration information of the first resource and the configuration information of the second resource. It should also be understood that the first network device and the first terminal device may be predefined. When the first terminal device determines that the configuration information of the first resource includes the ID of the second resource, or when the first terminal device determines the ID of the second resource, When the configuration information includes the ID of the first resource, the first terminal device determines whether to perform SRS-RSRP measurement according to the measurement result of CLI-RSSI measurement.

An example of adding the ID of the second resource (SRS-ResourceId) to the configuration information RSSI-ResourceConfigCLI of the first resource is given below.

Among them, srs-ResourceId SRS-ResourceId and SEQUENCE(SIZE(1..maxNrofIncludedSRS))OF SRS-ResourceId are the IDs of the second resource. It can be understood that the configuration information may include IDs of resources corresponding to multiple SRSs.

An example of adding the ID of the first resource (CLI-ResourceId) to the configuration information SRS-ResourceConfigCLI of the second resource is given below.

Among them, rssi-ResourceId-r16 RSSI-ResourceId-r16 is the ID of the resource corresponding to RSSI.

Optionally, when the first SRS-RSRP is greater than or equal to the second threshold, the first terminal device may send the first SRS-RSRP to the first network device, and correspondingly, the first network device receives the first SRS-RSRP. . The second threshold may be indicated by the first network device to the first terminal device, or the second threshold may be predefined, which is not limited in this embodiment of the present application.

In a possible implementation, the first threshold and/or the second threshold may be indicated by the first network device through reporting configuration information (reportQuantityCLI).

The first network device indicating the threshold by reporting the configuration information can be divided into the following two situations.

Case 1: The first network device indicates the first threshold and the second threshold in periodically reporting configuration information. An example of periodically reporting configuration information is given below.

Among them, CLI-RSSI-Threshold-r16 MeasTriggerQuantityCLI-r16 is the first threshold, and SRS-RSRP-Threshold-r16 MeasTriggerQuantityCLI-r16 is the second threshold.

Case 2: The first network device indicates the first threshold and the second threshold in the trigger/event (event) reporting configuration information. An example of the triggering reporting configuration information is given below.

Among them, i1-CLI-RSSI-Threshold-r16 MeasTriggerQuantityCLI-r16 is the first threshold, and i1-SRS-RSRP Threshold-r16 MeasTriggerQuantityCLI-r16 is the second threshold.

Further, the reported configuration information may also instruct CLI-RSSI and SRS-RSRP to be reported in combination. For example, the first network device sends the reporting configuration information to the first terminal device, and the first terminal device sends the measured CLI-RSSI and SRS-RSRP to the first network device according to the reporting configuration information. The SRS-RSRP may correspond to the CLI-RSSI. For example, the resources corresponding to the SRS-RSRP are part or all of the resources corresponding to the CLI-RSSI. An example of the reported configuration information is given below.

Among them, cli-rssi-rsrp-combined is the instruction to report the combination of CLI-RSSI and SRS-RSRP.

This method can be understood as explicitly instructing the first terminal device to report a combination of CLI-RSSI and SRS-RSRP through signaling. The aforementioned reported configuration information includes the first threshold and the second threshold, which can be understood as implicitly instructing the first terminal device to report CLI-RSSI and SRS-RSRP in combination. For example, the first terminal device and the first network device may predefine that when the first terminal device receives the first threshold and the second threshold, when reporting after the measurement is completed, the CLI-RSSI and SRS-RSRP need to be reported together. . Among them, combined with reporting, it can be understood that both CLI-RSSI and SRS-RSRP are reported. Alternatively, the first network device and the first terminal device may be predefined. When the first terminal device reports after the measurement is completed, it needs to report the CLI-RSSI and SRS-RSRP together. The embodiments of the present application do not limit this.

It should also be understood that the order of step 402 and step 403 is not limited. For example, the first terminal device may report the first CLI-RSSI before acquiring the first SRS-RSRP, or may report the first CLI-RSSI after acquiring the first SRS-RSRP. For example, the first SRS-RSRP and The first CLI-RSSI combination is reported.

It should also be understood that the above steps only take the first terminal device as an example for description. There may be multiple terminal devices in the communication system, and the above method can be applied to each terminal device. This is not limited in the embodiments of the present application.

In this method, the first terminal device determines whether to measure the SRS-RSRP after judging the size of the CLI-RSSI. For example, the SRS-RSRP is measured only when the CLI-RSSI is greater than or equal to the first threshold. This method avoids a large number of invalid measurements, reduces the power consumption of terminal devices and network devices, and improves the efficiency of interference measurement.

The above method saves the measured power consumption of the terminal device. The embodiment of the present application proposes another communication method, which saves the signaling overhead of the network device. This is explained in detail below. As shown in Figure 6, the method may include the following steps:

Step 601: The first network device sends second instruction information to the first terminal device, and correspondingly, the first terminal device receives the second instruction information.

The second indication information is used to indicate the third resource and resource unit. For example, the second indication information may indicate the starting position and the ending position of the third resource, or the second indication information may indicate the starting position and the length of the third resource, or the second indication information may indicate the starting position and the length of the third resource. The end position of the third resource and the length of the third resource. The second indication information may be carried in the measurement configuration information. For the measurement configuration information, refer to the relevant description of the first measurement configuration information and/or the second measurement configuration information in step 401, which will not be described again.

In one possible implementation, the above resource unit is a measurement granularity, for example, the subband measurement granularity of CLI-RSSI. The measurement granularity may be in units of physical resource blocks (PRBs), that is to say, the measurement granularity in the frequency domain. For example, the measurement granularity may be 4 PRBs. The resource unit may also have other names, such as resource granularity or resource subset, etc., which are not limited in the embodiments of this application. An example in which the second indication information is carried in the measurement configuration information is as follows.

Among them, PRBGranu INTEGER(4..maxNrofPhysicalResourceBlocksPlus1) is the configuration of measurement granularity.

In another possible implementation, the second indication information is a bitmap. For example, the second indication information indicates a period (ie, measurement granularity) of the resource to be measured through bits. For example, as shown in (a) of FIG. 7 , the second indication information indicates, through a bitmap, a period of the resource on the third resource to be measured for RSRP (ie, resource T). Correspondingly, an example of the second indication information is as follows.

Configuration for measuring granularity.

Or, as shown in (b) of FIG. 7 , the first network device indicates the starting position and the ending position of a cycle of the resource to be measured for RSRP through a bit pattern.

Alternatively, the first network device indicates the length of each resource of the resources to be measured RSRP through bits. Correspondingly, an example of the second indication information is as follows.

Among them, MeasurePRB SEQUENCE{

NrofPRBsSegment1INTEGER(4..maxNrofPhysicalResourceBlocksPlus1),

NrofPRBsSegment2INTEGER(4..maxNrofPhysicalResourceBlocksPlus1),

…

} is the configuration of the length of N fourth resources.

It should be understood that the above is only an example of the way in which the second indication information indicates the resource unit or the fourth resource, and is not a limitation. Other equivalent alternative ways should also be within the protection scope of this application.

Optionally, the first network device may also send third indication information to the first terminal device, and correspondingly, the first terminal device receives the third indication information.

The third indication information may be used to indicate the fifth resource. The fifth resource is the resource to be measured. For example, the entire fifth resource can be a resource used by the first terminal device to perform CLI-RSSI measurement. The fifth resource can be a part of the above-mentioned N fourth resources. M is less than N. , or the fifth resource may be all the above-mentioned N fourth resources, M equal to N. For example, the third indication information may indicate the starting position and the ending position of the third resource and the fifth resource; or the third indication information may indicate the starting position and the ending position of the fifth resource; or the second indication information The length of the third resource and the fifth resource may be indicated. The manner in which the third indication information indicates the third resource may refer to the above-mentioned manner in which the second indication information indicates the third resource, which will not be described again.

Step 602: The first terminal device performs measurement on each of the N fourth resources and obtains N measurement results.

Among them, the N fourth resources are respectively subsets of the third resources. In other words, the N fourth resources occupy the third resources and do not overlap, or the third resources are divided into N fourth resources. The size of each of the N fourth resources may be the same as the resource unit. It can be understood that the first terminal device can divide the third resource in step 801 into N fourth resources according to the resource unit. For example, the first terminal device may perform the operation in the frequency domain according to the resource unit. The third resource is evenly divided into lengths, as shown in (a) in Figure 8, N is 5, and the third resource is evenly divided into five equal parts.

In another example, the first terminal device can divide the third resource into multiple unequal parts according to the length of the resource unit in the frequency domain. For example, N is 3, and the multiple resources have no intersection with each other, as shown in Figure 8 As shown in (b), the third resource is divided into fourth resource 1, fourth resource 2 and fourth resource 3, where the length of the fourth resource 1 in the frequency domain is the length of the resource unit in the frequency domain. The length of resource 2 in the frequency domain is twice the length of the resource unit in the frequency domain, and the length of the fourth resource 3 in the frequency domain is three times the length of the resource unit in the frequency domain. The embodiments of the present application do not limit this.

It can be understood that, before determining the N fourth resources according to the resource units, the first terminal device may determine the resource units according to the second indication information. For example, the first terminal device may determine the resource units according to the second indication information, or, The bit pattern determines the resource unit.

The above N is an integer greater than or equal to 2, that is to say, the first terminal device has at least two resources for performing measurement. In other words, the first terminal device divides the third resource into at least two parts. The measurement performed by the first terminal device may be at least one of CLI-RSSI measurement or SRS-RSRP measurement. For example, N is 2, and the two fourth resources can be divided into fourth resource A and fourth resource B. The first terminal device can perform CLI-RSSI measurement on the fourth resource A, and the first terminal device can also perform CLI-RSSI measurement on the fourth resource A. SRS-RSRP measurement is performed on the fourth resource A. Of course, the first terminal device may also perform CLI-RSSI measurement and SRS-RSRP measurement on the fourth resource A. The fourth resource B is similar to the fourth resource A and will not be described again.

It can be understood that before the first terminal device performs the measurement, the first terminal device also receives the SRS. The SRS may be from the second terminal device. Specifically, reference may be made to the relevant description of step 403, which will not be described again. In this method, the first terminal device may be one of the aforementioned terminal devices, and the first network device may be one of the aforementioned network devices.

It should also be understood that the first terminal device may also include multiple terminal devices, and the second indication information may be multiple indication information corresponding to the multiple terminal devices. For example, each indication information in the multiple indication information corresponds to a Terminal Equipment. The second instruction information is carried in the measurement configuration information, and the first network device sends a plurality of measurement configuration information to a plurality of terminal devices, and the plurality of measurement configuration information corresponds to the plurality of terminal devices one-to-one. In a possible way, when the second indication information directly indicates the resource unit, the first network device may also indicate the order of multiple terminal devices, so that the multiple terminal devices determine the resources for performing SRS-RSRP measurement respectively, or, A network device may also indicate the start position or end position of resources for performing SRS-RSRP measurement corresponding to multiple terminal devices, or the first network device may predefine the resources for performing SRS-RSRP measurement with multiple terminal devices. The sequence is not limited in the embodiments of this application.

In another possible way, when the first network device indicates the starting position and the resource unit of the second resource, the first terminal device can be in the indicated frequency domain starting position + n * resource unit ~ frequency domain starting position + (n+1)* resource unit, or the corresponding sub-band position on the bitmap is measured, threshold determined and reported.

Optionally, the method may also include step 803: the first terminal device sends the second SRS-RSRP and the index of the sixth resource in the fifth resource to the first network device.

The sixth resource is a resource for the first terminal device to perform SRS-RSRP measurement. The sixth resource is part of the fifth resource. The first terminal device obtains at least two SRS-RSRPs after performing SRS-RSRP measurements on multiple (at least two) sixth resources. In one possible implementation, the first terminal device reports the SRS-RSRP to the first network device. RSRP, the index of the resource corresponding to the SRS-RSRP in the fifth resource is also reported, so that the first network device can easily obtain the correspondence between the SRS-RSRP and multiple measurement resources. In another possible implementation, the first terminal device may report SRS-RSRP in order, and the order may be the order of multiple sixth resources in the fifth resource.
