Description

Communication method, device and system

Technical Field

The embodiment of the application relates to the field of communication. And more particularly, to a communication method, apparatus, and system.

Background

During signal transmission, out-of-band leakage (out of band emission) and spurious leakage (spurious emission) generally exist in component carriers (component carrier, CCs), and particularly on CCs with frequency domains closely spaced may generate strong adjacent band (inter band) interference due to the out-of-band leakage, and a communication device may fail to receive signals on the CCs. To avoid such interference, users receiving signals on adjacent frequencies may be spatially isolated by scheduling, which requires measuring distances and Path Loss (PL) between users. The current New Radio (NR) protocol defines a measurement mechanism for inter-user interference that can be used to calculate the path loss. However, in the interference measurement process, the receiving users of the sounding reference symbols (sounding reference symbol, SRS) need to measure all transmitting users of the SRS, which causes large power consumption and signaling overhead, and affects measurement efficiency.

Therefore, how to reduce the power consumption and signaling overhead of interference measurement and improve the measurement efficiency is a problem to be solved.

The terminal is connected with the wireless access network equipment in a wireless mode, and the wireless access network equipment is connected with the core network in a wireless or wired mode. The core network device and the radio access network device may be separate physical devices, or may integrate the functions of the core network device and the logic functions of the radio access network device on the same physical device, or may integrate the functions of part of the core network device and part of the radio access network device on one physical device. The terminals and the radio access network device may be connected to each other by wired or wireless means. Fig. 1 is only a schematic diagram, and other network devices may be further included in the communication system, for example, a wireless relay device and a wireless backhaul device may also be included, which are not shown in fig. 1.

The radio access network device may be a base station (base station), an evolved NodeB (eNodeB), a transmission and reception point (transmission reception point, TRP), a next generation NodeB (gNB) in a fifth generation (5th generation,5G) mobile communication system, a next generation base station in a sixth generation (6th generation,6G) mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system, etc.; the present application may also be a module or unit that performs a function of a base station part, for example, a Central Unit (CU) or a Distributed Unit (DU).

Of course, communication between 110a and 120i may be performed via an interface protocol between base stations, and in this case, 120i is also a base station with respect to 110 a. Thus, both the base station and the terminal may be collectively referred to as a communication device, 110a and 110b in fig. 1 may be referred to as a communication device having base station functionality, and 120a-120j in fig. 1 may be referred to as a communication device having terminal functionality.

Wherein, in the embodiments of the present application, the term "wireless communication" may also be simply referred to as "communication".

In order to facilitate understanding of the aspects of the embodiments of the present application, a description will be made of related concepts.

1. Channel state information reporting configuration (CSI-ReportConfig): the method is mainly used for configuring parameters related to channel state reporting, such as reporting types, reported measurement indexes and the like. Reporting a configuration identifier (reportConfigId), which is an identifier (Id) number of the CSI-ReportConfig, for marking the CSI-ReportConfig; a channel measurement resource (resource-Reference Signal, CSI-RS) resource for configuring channel state information-Reference Signal (CSI-RS) resources of channel measurement, associated to resource configuration by CSI-resource configuration id; interference measurement resources (CSI-IM-resources forinterference), resources of CSI-RS configured for interference measurement, are associated to the resource configuration by CSI-ResourceConfigId.

Optionally, parameters related to CSI reporting may include CSI reporting type (reportConfigType), CSI reporting amount (reportquality), etc., where CSI reporting type may be classified into periodic, semi-persistent, and aperiodic reporting; the network device may be configured by different reporting amounts, so that the terminal device reports different CSI, including CSI-RS resource indication (CSI-RS resource indicator, CRI), rank Indicator (RI), precoding matrix indication (Pre-coding Matrix Indicator, PMI), channel quality indication (Channel Quantity Indicator, CQI), and so on.

2. Channel state information resource configuration (CSI-ResourceConfig): resource-related information for configuring CSI measurements. May include reporting resource identification (CSI-ResourceConfigId) and/or resource-binding queues (CSI-RS-resourcesitsist), etc. Wherein, CSI-ResourceConfigId is used to mark the CSI-ResourceConfig; the CSI-RS-resourcesist may include a set of resources for channel measurements and a set of resources for interference measurements.

3. Channel state information (channel state information, CSI): during the transmission of a signal from a transmitting end to a receiving end over a wireless channel, fading occurs due to the possibility of scattering, reflection and attenuation of energy with distance. The CSI is used to characterize the wireless channel and may include at least one of CQI, PMI, CRI, synchronization signal and physical broadcast channel block (synchronization signal and physical broadcast channel block, SSB) resource indication (SSB resource indicator, SSBRI), layer Indication (LI), RI, L1-reference signal received power (reference signal received power, RSRP), and L1-signal-to-interference and noise ratio (signal to interference plus noise ratio, SINR). CSI may be transmitted by the terminal device to the network device over a physical uplink control channel (physical uplink control channel, PUCCH) or a physical uplink shared channel (physical uplink share channel, PUSCH).

CSI report (CSI report): the CSI report is sent by the terminal to the base station, and is used for the network device to learn the channel state when the network device sends downlink information to the terminal device. The 1 CSI report is used to instruct the terminal device to feed back 1 CSI, and different CSI may correspond to different frequency bands, different transmission hypotheses or different reporting modes.

In general, one CSI report may be associated with 1 reference signal resource for channel measurement, and may also be associated with 1 or more reference signal resources for interference measurement. One CSI report corresponds to one transmission resource, i.e. a time-frequency resource used by the terminal device to transmit the CSI.

5. Reference signal: is a known signal provided by the transmitting end to the receiving end for channel estimation or channel sounding. In the embodiment of the application, the reference signal may be used for channel measurement, interference measurement, etc., such as measuring parameters of reference signal received quality (reference signal receiving quality, RSRQ), SINR, CQI, PMI, etc.

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

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

7. Complementary time-division duplex (TDD) (complementary TDD) frame structure: two sets of frame structures with complementary downlink (D) and uplink (U) sub-frame ratios, for example, one set of frame structures is D: u=4:1, and one set of frame structures is D: u=1:4, and U and D resources are available for call on each orthogonal frequency division multiplexing symbol (orthogonal frequency division multiplexingsymbol, OS) through the complementary frame structures.

Cc: the carrier unit for carrier aggregation (carrier aggregation, CA), for example, may have a maximum bandwidth of 20MHz per CC. Each CC may correspond to an independent cell (cell), each CC may have a corresponding index, for example, a primary CC index is fixed to 0, and the index of each UE's secondary CC may be configured through UE-specific radio resource control (radio resource control, RRC) signaling. The CCs aggregated by a UE are typically from the same eNodeB.

In the signal transmission process, out-of-band leakage and spurious leakage generally exist in the CC, especially on the CC with a relatively close frequency domain interval, stronger adjacent frequency interference can be generated due to the out-of-band leakage, and the signal receiving on the CC may fail. This is stated below taking an industrial scenario as an example. With the development of NR, industrial scene expansion and demand evolution, factory indoor deployment needs to meet the demands of mixed services. Hybrid traffic currently includes two classes: upstream ultra-wideband communication (uplink centric broadband communication, UCBC), such as industrial camera related services; ultra-high reliability ultra-low latency communications (ultra reliable low latency communications, URLLC), such as gripper control related traffic of robotic arms. When deployed in the same area for both types of scenarios, it may be necessary to configure with the adjacent frequency within one bandwidth (band) due to the scarcity of the spectrum. For UCBC traffic, the uplink (uplink) traffic occupies a relatively high amount, so more uplink subframe resources (e.g., D: u=1:4 or 3:7) are needed in the frame structure, where D represents downlink and U represents uplink. In addition, since the URLLC needs to guarantee service transmission delay, an ultra-wideband complementary time division duplex mode (intra band complementary TDD) frame structure needs to be adopted. An example of a frame structure is shown in fig. 2, where CC1, CC2 and CC4 are occupied by UCBC traffic, and CC3 and CC5 are configured with intraband complementary TDD for supporting URLLC traffic. For such a scenario, taking one UCBC terminal transmission of CC4 as an example, when transmitting, the transmitted signal has out-of-band leakage and spurious leakage in addition to the valid signal within the CC4 bandwidth. Because the frequency domains of the CC4 and the CC5 are closely spaced, the out-of-band leakage generated by the CC4 can leak to the CC5, and stronger adjacent frequency leakage interference is generated for a user receiving signals on the D sub-frame of the CC5, so that the SINR of the user is reduced, and the user is likely to fail to receive the signals. Because the transmission of CC3 and CC5 is the URLLC service, the URLLC service has the characteristics of low delay and high reliability, and the failure of the received signal can have serious negative influence on the service.

To cope with such interference, it is necessary to spatially isolate UCBC users and URLLC users by scheduling (e.g., schedule users farther away to transmit at the same time), and to perform frequency domain pulling (e.g., schedule users farther away to transmit on CC4 closer to CC5, and schedule users closer to transmit on CCs 1 and 2 farther away from CC 5). To achieve this, the distance and path loss between scheduled users need to be measured. The path loss can be calculated through interference measurement. For example, current NR protocols define a measurement mechanism of inter-user interference, which may be based on cross-link interference SRS (cross-link interference SRS, CLI-SRS) for interference measurements. Specifically, the cell configures a transmitting user to transmit a measurement signal, and configures a receiving user to receive the measurement signal on a corresponding time-frequency code resource. The SRS-RSRP of the SRS sequence transmitted over the segment of bandwidth, or the received signal strength indication (CLI received signal strength indication, CLI-RSSI) of the segment of measurement bandwidth, is obtained by receiving the user measurement. And reporting the SRS-RSRP and the CLI-RSSI obtained by measurement by a receiving user according to the reporting configuration of the cell, and calculating the path loss between the transmitting user and the receiving user by the cell through the acquired CLI-SRS transmitting power of the transmitting user and the SRS-RSRP and the CLI-RSSI reported by the receiving user. In the ultra bandwidth (intraBand) scenario, the interaction flow of the large-capacity user number 100+, URLLC user number up to 900, cell, transmitting user (URLLC user group) and receiving user (UCBC user group) may be as shown in fig. 3:

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

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

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

Step 304: the URLLC users 1 to 32 transmit SRS to UCBC users.

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

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

Step 307: the URLLC users 33 to 64 transmit SRS to UCBC users.

Step 308: the UCBC user sends measurements for the URLLC users 33-64 to the UCBC cell.

And so on until the UCBC user sends measurements for the URLLC users 869-900 to the UCBC cell.

The cell configuration resources, the configuration measurement configuration and the reporting configuration in the above steps can be understood as the base station configuration resources, the configuration measurement configuration and the reporting configuration for managing the cell. The measurement configuration may indicate, among other features, the time start position and duration of the present measurement, the frequency domain start position and duration, and the periodicity/triggerability of the measurement. When the SRS configuration on the transmitting side is periodic transmission, the corresponding measurement configuration is configured according to the corresponding period and offset (offset). Reporting configurations fall into two types of measurement quantities: the method comprises the steps that SRS-RSRP and CLI-RSSI are reported in a separated (choice) mode, a user reports measurement results higher than a threshold value, the CLI-RSSI in the report content comprises identifiers (rsti-resource-r 16) of measurement resources corresponding to the RSSI, the SRS-RSRP comprises identifiers (SRS-resource-id) of the measurement resources corresponding to the RSRP, the identifiers are consistent with the resource identifiers configured in the measurement configuration, and network equipment can determine which measurement result of the measurement resources is according to the identifiers after receiving the report results. Reporting configurations can be divided into two categories, periodic reporting and event (event) reporting. When the user to be measured performs measurement and adopts periodic reporting configuration, reporting the measurement results between the last reporting and the current reporting, wherein the measurement results correspond to SRS/RSSI-resource information of one position; when the user to be tested performs measurement and event reporting configuration is adopted, the user to be tested triggers reporting when the i1 event is met on the measured resource, and the reporting content carries SRS/RSSI-resource eid.

In the above scenario, each UCBC user needs to measure 900 URLLC users, and assuming that only 1 antenna (corresponding to one time-frequency comb code resource) of the URLLC is measured, 900 sets of measurement configurations need to be issued, and the current protocol only supports lengths of 32 RSRP/64 RSSI (corresponding to the measurement capability definition of the UE), and these measurements may be issued in a sequence (sequence) manner in one RRC signaling, where each sequence may indicate a maximum of 32 RSRP measurements or relevant configurations of 64 RSSI measurements. For each UCBC user, if the path loss between UEs needs to be measured based on RSRP, the corresponding measurement signaling single bearer 32 users' measurement configuration needs to continuously receive about 29 signaling. Assuming that the URLLC user transmits SRS according to the period of 5ms, after the measurement configuration and the reporting configuration of the UCBC user are issued, the SRS is measured within 2.5ms on average and then reported, and the total time of one round of measurement is 29×2.5×75ms, so that larger issuing cost and reporting cost exist. In addition, only a certain frequency domain starting position is indicated in the existing measurement configuration, under the condition that a plurality of users to be measured are needed, each user needs to configure measurement configuration of all the users on the opposite side in a time-sharing manner, and considering that the measurement capability of the users is limited, the users need to issue the measurement configuration in a time-sharing manner and in a time-sharing manner, so that the measurement configuration is complex, and the signaling issuing and reporting costs are high.

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

step 401: the first network device transmits the first measurement configuration information and the second measurement configuration information to the first terminal device, and 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 a cross-link interference received signal strength indicator CLI-RSSI of the first resource, for example, the first measurement configuration information may include information of the first resource, for example, the information of the first resource may be a starting position and a length of the first resource in a frequency domain, or the information of the first resource may be a starting position and an ending position of the first resource in the frequency domain. The first measurement information may further include a start position and a duration of the CLI-RSSI measurement in the time domain, or the first measurement information may include a start position and an end position of the CLI-RSSI measurement in the time domain, in other words, a time of the CLI-RSSI measurement may be included in the first measurement information. The first measurement information may also include the CLI-RSSI measurement as a periodic measurement or the CLI-RSSI measurement as a trigger (event) measurement.

The second measurement configuration information may be used to measure a sounding reference symbol reference signal received power SRS-RSRP of the second resource, for example, the second measurement configuration information may include information of the second resource, for example, the information of the second resource may be a start position and a length of the second resource in a frequency domain, or the information of the second resource may be a start position and an end position of the second resource in the frequency domain. The second measurement information may further include a start position and a duration of the SRS-RSRP measurement in the time domain, or the second measurement information may include a start position and an end position of the SRS-RSRP measurement in the time domain, in other words, a time of the SRS-RSRP measurement may be included in the second measurement information. The second measurement information may also include the SRS-RSRP measurement this time as a periodic measurement or the SRS-RSRP measurement this time as a triggered measurement.

The second resource and the first resource may be the same, or the second resource may be part of the first resource.

The first resource and the second resource are identical, and it may be understood that the time-frequency position of the first resource and the time-frequency position of the second resource are identical, for example, as shown in (a) in fig. 5, the corresponding resources of the first resource and the second resource in the time domain completely overlap, and the corresponding resources in the frequency domain also completely overlap.

The second resource is part of the first resource, and it can be understood that the time-frequency position of the second resource is within the time-frequency range of the first resource. Illustratively, 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, and the first resource is the same as the resource corresponding to the second resource in the frequency domain, for example, as shown in (b) of fig. 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 ending position E2 of the resource corresponding to the second resource in the time domain is before the ending position E1 of the resource corresponding to the first resource in the time domain. Illustratively, the second resource is identical to the first resource in the time domain within the range of the first resource in the frequency domain, for example, as shown in fig. 5 (c), the starting position S2 of the second resource in the frequency domain is after the starting position S1 of the first resource in the frequency domain, and the ending position E2 of the second resource in the frequency domain is before the ending position E1 of the first resource in the frequency domain. It should be understood that fig. 5 is only an example and not limited, and for example, the second resource is a part of the first resource, where the resource corresponding to the second resource in the frequency domain is within the range of the resource corresponding to the first resource in the frequency domain, 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, which is not limited in the embodiment of the present application. In other words, the second resource is a non-null subset of the first resource, such as the time domain resource corresponding to the second resource is a non-null subset of the time domain resource corresponding to the first resource, and/or the frequency domain resource corresponding to the second resource is a non-null subset of the frequency domain resource corresponding to the first resource.

One possible implementation, the first resource and the second resource are carriers, and another possible implementation, the first resource and the second resource are partial Bandwidth (BWP), or the first resource is a carrier, and the second resource is BWP, or vice versa.

It should be understood that the first network apparatus in step 401 may be the aforementioned radio access network device or core network device, and the first terminal apparatus 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 appreciated that the first terminal device may include at least one terminal device, and illustratively the first terminal device may be a plurality of UCBC terminal devices, as embodiments of the present application are not limited in this regard.

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

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

It should be appreciated that the first terminal device also receives the SRS prior to the first terminal device measurement. The SRS may be from the second terminal apparatus. In one possible manner, the second terminal apparatus periodically transmits the SRS to the first terminal apparatus. The period in which the second terminal apparatus transmits the SRS to the first terminal apparatus may be configured by the second network apparatus, for example, the second network apparatus transmits RRC signaling including a transmission period of the SRS and offset (offset) to the second terminal apparatus. In another possible manner, the second terminal device may transmit the SRS to the first terminal device in a triggered manner (event), for example, when the second network device notifies the second terminal device to instantaneously measure uplink channel information on a certain resource of the own cell, or when the second network device notifies the second terminal device to instantaneously measure inter-cell/intra-cell interference information on a certain resource, the second terminal device may transmit the 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.

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

Step 403: and when the first CLI-RSSI is greater than or equal to a first threshold value, the first terminal device measures second resources according to the second measurement configuration information, and acquires a first SRS-RSRP.

That is, the size of the first CLI-RSSI may 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 transmitted together or may be transmitted separately. For example, the first network device may send first measurement configuration information to the first terminal device, where the first terminal device determines that the first CLI-RSSI is greater than or equal to the first threshold, and may send indication information to the first network device, where the indication information 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. In addition, the first network device may send the first measurement configuration information and the second measurement configuration information to the first terminal device, and when the first terminal device determines that RSRP is not required to be measured, the first terminal device may ignore information about the second resource in the second measurement configuration information, that is, in this case, the resource indicated by the resource information included in the second measurement configuration information is not used for RSRP measurement, and of course, it is understood that whether the second resource is used for RSRP measurement is only for this measurement procedure and is not a limitation on the use of the resource.

Alternatively, the first network device may transmit first indication information for indicating whether to perform SRS-RSRP measurement according to a measurement result of CLI-RSSI measurement to the first terminal device. For example, whether to perform SRS-RSRP measurement may be determined according to the measurement result of CLI-RSSI measurement according to the identification information of the first resource and the identification information indication 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 first resource to the identification information of the second resource. The identification information of the first resource may be a resource identification (Identity document, ID) of the first resource, and the ID of the first resource may be CLI-resource ID, for example. The identification information of the second resource may be a resource ID of the second resource, and for example, the ID of the second resource may be SRS-resource ID. Then, the first indication information may be adding the ID (SRS-ResourceId) of the second resource to the configuration information RSSI-resourceconfgcli of the first resource, or adding the ID (CLI-ResourceId) of the first resource to the configuration information SRS-resourceconfgcli of the second resource. It may be appreciated 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, and the first terminal device determines whether to perform SRS-RSRP measurement according to a measurement result of CLI-RSSI measurement when the first terminal device determines that the ID of the second resource is included in the configuration information of the first resource or when the first terminal device determines that the ID of the first resource is included in the configuration information of the second resource.

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

Wherein SRS-ResourceId SRS-ResourceId and SEQUENCE (SIZE (1. Maxnroflncluddsrs)) OF SRS-ResourceId is the ID OF the second resource. It can be appreciated that the configuration information can include IDs of resources corresponding to the plurality of SRS.

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

/>

Wherein RSSI-resource-r 16 RSSI-resource-r 16 is the ID of the resource to which the RSSI corresponds.

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 by the embodiment of the present application.

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

The first network device may be further classified into the following two cases by reporting the configuration information indication threshold.

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

Wherein CLI-RSSI-Threshold-r16 MeasTriggerQuantunityCLI-r 16 is a first Threshold, SRS-RSRP-Threshold-r16 MeasTriggerQuantunityCLI-r 16 is a second Threshold.

Case 2: the first network device indicates the first threshold and the second threshold in triggered/event (event) reporting configuration information, an example of which is given below.

/>

Wherein i1-CLI-RSSI-Threshold-r16 MeasTriggerQuantunityCLI-r 16 is a first Threshold, and i1-SRS-RSRP Threshold-r16 MeasTriggerQuantunityCLI-r 16 is a second Threshold.

Further, the reporting configuration information may also indicate that CLI-RSSI and SRS-RSRP are reported in combination. Illustratively, the first network device transmits reporting configuration information to the first terminal device, and the first terminal device transmits the measured CLI-RSSI and SRS-RSRP to the first network device according to the reporting configuration information. The SRS-RSRP may correspond to CLI-RSSI, and for example, the SRS-RSRP corresponds to a part or all of the CLI-RSSI corresponding resources. An example of this reporting configuration information is given below.

The CLI-rsi-RSRP-combined is an indication reported by the combination of the CLI-RSSI and the SRS-RSRP.

This approach can be understood as explicitly instructing the first terminal device to combine reporting CLI-RSSI and SRS-RSRP by signaling. The reporting configuration information includes a first threshold and a second threshold, which can be understood as implicitly indicating the first terminal device to combine the reported CLI-RSSI and SRS-RSRP. For example, the first terminal device and the first network device may be predefined, and when the first terminal device receives the first threshold value and the second threshold value, and reports after the measurement is completed, the CLI-RSSI and SRS-RSRP are required to be reported in combination. Wherein, the combined report can be understood as the report of both CLI-RSSI and SRS-RSRP. Or, the first network device and the first terminal device may be predefined, and when the first terminal device reports after the measurement is completed, the CLI-RSSI and SRS-RSRP need to be reported in combination. The embodiment of the present application is not limited thereto.

It should also be appreciated that the order of steps 402 and 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, report the first SRS-RSRP and the first CLI-RSSI in combination.

It should also be understood that the above steps are only described by taking the first terminal device as an example, and that there may be a plurality of terminal devices in the communication system, and the above method may be applied to each terminal device, which is not limited by the embodiment of the present application.

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

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

step 601: the first network device transmits second instruction information to the first terminal device, and the first terminal device receives the second instruction information correspondingly.

The second indication information is used to indicate a third resource and a resource unit. For example, the second indication information may indicate a start position and an end position of the third resource, or the second indication information may indicate a start position and a length of the third resource, or the second indication information may indicate an end position and a length of the third resource. The second indication information may be carried in measurement configuration information, and the measurement configuration information may refer to the description related to the first measurement configuration information and/or the second measurement configuration information in step 401, which is not described herein.

One possible implementation, the resource unit is a measurement granularity, such as a subband measurement granularity of CLI-RSSI. The measurement granularity may be in units of physical resource blocks (physical resource block, PRBs), that is to say in the frequency domain, for example the measurement granularity may be 4 PRBs. The resource unit may also be referred to by other names, such as granularity of resources or subset of resources, etc., which are not limited by the embodiments of the present application. One example of the second indication information carried on the measurement configuration information is as follows.

Wherein PRBGranu inter (4..maxnrof physical resource blocks plus 1) is the configuration of the measurement granularity.

Yet another possible implementation, the second indication information is a bit pattern (bitmap). Illustratively, the second indication information indicates one period (i.e., measurement granularity) of the resource to be measured by a bit. Illustratively, as shown in (a) of fig. 7, the second indication information indicates one period of the resource (i.e., resource T) of the RSRP to be measured on the third resource by the bitmap. Correspondingly, one example of the second indication information is as follows.

/>

Configuration for measuring granularity.

Alternatively, as shown in (b) of fig. 7, the first network device indicates the start position and the end position of one cycle of the resource of the RSRP to be measured by the bit pattern.

Still alternatively, the first network device indicates the length of each resource of the resources of the RSRP to be measured by a bit. Correspondingly, one example of the second indication information is as follows.

Therein, measurePRB SEQUENCE {

NrofPRBsSegment1 INTEGER(4..maxNrofPhysicalResourceBlocksPlus1),

NrofPRBsSegment2 INTEGER(4..maxNrofPhysicalResourceBlocksPlus1),

…

I.e. the configuration of the length of the N fourth resources.

It should be understood that the foregoing is merely an example of the manner in which the second indication information indicates the resource unit, or the fourth resource is indicated, and that other equivalent alternatives are also within the scope of the present application.

Alternatively, 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 a fifth resource. The fifth resource is a resource to be measured, for example, the whole of the fifth resource may be a resource of the first terminal device performing CLI-RSSI measurement, the fifth resource may be a part of the N fourth resources, M is smaller than N, or the fifth resource may be all of the N fourth resources, and M is equal to N. For example, the third indication information may indicate a start position and an end position of the third resource and the fifth resource; alternatively, the third indication information may indicate a start position and an end position of the fifth resource; alternatively, the second indication information may indicate lengths of the third resource and the fifth resource. The method for indicating the third resource by the third indication information may refer to the method for indicating the third resource by the second indication information, which is not described herein.

Step 602: the first terminal apparatus performs measurement on each of the N fourth resources, and acquires N measurement results.

The N fourth resources are 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. Each of the N fourth resources may be the same size as a resource unit. It may be appreciated that the first terminal apparatus may divide the third resource in step 801 into N fourth resources according to the resource unit. For example, the first terminal apparatus may equally divide the third resource according to the length of the resource unit in the frequency domain, and as shown in (a) of fig. 8, N is 5, and the third resource is equally divided into five equal parts.

As yet another example, the first terminal apparatus may divide the third resource into unequal multiples, for example, N is 3, according to the length of the resource unit in the frequency domain, and the multiple resources are mutually disjoint, as shown in (b) of fig. 8, the third resource is divided into a fourth resource 1, a fourth resource 2, and a fourth resource 3, wherein 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 the fourth resource 2 in the frequency domain is 2 times the length of the resource unit in the frequency domain, and the length of the fourth resource 3 in the frequency domain is 3 times the length of the resource unit in the frequency domain. The embodiment of the present application is not limited thereto.

It may be appreciated that the first terminal apparatus may determine the resource unit according to the second indication information before determining the N fourth resources according to the resource unit, for example, the first terminal apparatus may determine the resource unit according to the resource unit included in the second indication information, or the bit pattern.

The N is an integer greater than or equal to 2, that is, at least two resources are used for the first terminal device to perform measurement. In other words, the first terminal apparatus divides the third resource into at least 2 parts. The measurement performed by the first terminal device may be at least one of a CLI-RSSI measurement or an SRS-RSRP measurement. For example, N is 2, the two fourth resources may be divided into a fourth resource a and a fourth resource B, the first terminal device may perform CLI-RSSI measurement on the fourth resource a, the first terminal device may also perform SRS-RSRP measurement on the fourth resource a, and 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 appreciated that the first terminal apparatus also receives the SRS before the first terminal apparatus performs the measurement. The SRS may be from the second terminal apparatus. Specifically, reference may be made to the description of step 403, which will not be repeated. The first terminal device in the method may be one of the terminal apparatuses described above, and the first network device may be one of the network apparatuses described above.

It should also be understood that the first terminal apparatus may further include a plurality of terminal devices, and the second indication information may be a plurality of indication information corresponding to the plurality of terminal devices, for example, each of the plurality of indication information corresponds to one terminal device. The second indication information is carried in measurement configuration information, 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 by one. In a possible manner, when the second indication information directly indicates the resource unit, the first network apparatus may further indicate an order of the plurality of terminal devices, so that the plurality of terminal devices determine resources for performing SRS-RSRP measurement respectively, or the first network apparatus may further indicate a start position or an end position of the resources for performing SRS-RSRP measurement corresponding to the plurality of terminal devices, or the first network apparatus may predefine an order of the resources for performing SRS-RSRP measurement with the plurality of terminal devices, which is not limited in the embodiment of the present application.

In another possible manner, when the first network device indicates the starting position and the resource unit of the second resource, the first terminal device may perform measurement, threshold decision and reporting at the indicated frequency domain starting position+n×resource unit to the indicated frequency domain starting position + (n+1) ×resource unit, or the corresponding subband position on the bitmap.

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

Wherein 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 acquires at least two SRS-RSRP after performing SRS-RSRP measurement on a plurality of (at least two) sixth resources, and when the first terminal device reports the SRS-RSRP to the first network device, the first terminal device reports the index of the resource corresponding to the SRS-RSRP in the fifth resource at the same time, so that the first network device is convenient to acquire the correspondence between the SRS-RSRP and the plurality of measurement resources.
