Description

Method and device for interference measurement

Technical Field

The present application relates to the field of communications, and more particularly, to a method and apparatus for interference measurement.

Background

In the fifth generation (5th generation, 5G) communication system, high frequency communication may be adopted, that is, signals in the ultra high frequency band (>6GHz) are adopted to transmit data. One of the major problems with high frequency communications is: the signal energy drops sharply as the signal transmission distance increases, resulting in a short signal transmission distance. In order to overcome the problem, the high-frequency communication adopts a beam technology, and the large-scale antenna array is used for weighting processing, so that the signal energy is concentrated in a smaller range to form a signal similar to a light beam, namely a beam, thereby improving the transmission distance.

When the high-frequency communication adopts the beam technology, the network equipment can generate different sending beams and point to different transmission directions. Specifically, the network device may determine which transmission beam to use to transmit data to the terminal device through the result of beam measurement performed by the terminal device. The basic flow of beam measurement comprises the following steps: firstly, network equipment configures a plurality of measurement resources for measuring the quality of a transmission beam to terminal equipment, wherein each resource corresponds to one transmission beam; secondly, for each resource network device, transmitting a measurement signal on the resource particle corresponding to the resource through the corresponding transmission beam; then, the terminal equipment measures the measurement signal sent on the resource particle corresponding to each resource, thereby determining the quality of the wave beam corresponding to each resource; finally, the terminal device reports the index of the resource corresponding to the beam which can be used for transmitting data to the network device. That is, according to the result of the beam measurement, the network device determines an index of a part or all of the resources from the configured multiple measurement resources, and determines that the transmission beam corresponding to the part or all of the resources can be used for transmitting data. Further, in order to avoid the network device using two transmission beams with strong mutual interference (interference) to transmit data for multiple terminal devices, interference between the transmission beams needs to be known.

The prior art provides a scheme for measuring quality of transmission beams and interference information between transmission beams, where a network device configures multiple channel measurement resources for beam quality measurement and interference measurement resource sets for interference measurement, which are the same in number as the channel measurement resources, and each interference measurement resource set is used to measure interference information of one channel measurement resource, so as to measure interference information of all configured channel measurement resources. The scheme can realize the measurement of the beam interference information, but the set of interference measurement resources needing to be configured is too many, so that the configuration resource overhead is too large. Therefore, how to measure the quality of the beam and the interference with low overhead is an urgent problem to be solved.

In addition, various storage media described herein can represent one or more devices and/or other machine-readable media for storing information. The term "machine-readable storage medium" can include, without being limited to, wireless channels and various other media capable of storing, containing, and/or carrying instruction(s) and/or data.

As shown in fig. 1, the system 100 includes a network device 102, and the network device 102 may include 1 antenna or multiple antennas. Such as

antennas

104, 106, 108, 110, 112, and 114. Additionally, network device 102 may additionally include: a transmitter chain and a receiver chain.

It will be appreciated by those of ordinary skill in the art that the transmitter and receiver chains can each comprise a plurality of components associated with signal transmission and reception (e.g., processors, modulators, multiplexers, demodulators, demultiplexers, antennas, etc.).

Network device 102 may communicate with terminal devices, such as terminal device 116 and terminal device 122 shown in fig. 1. However, it is understood that network device 102 may communicate with any number of terminal devices similar to terminal device 116 or terminal device 122.

End devices

116 and 122 may be various devices that communicate with network device 102, for example, end device 116 may be a cellular phone, a smart phone, a laptop, a handheld communication device, a handheld computing device, a satellite radio, a global positioning system, a PDA, and/or any other suitable device for communicating over wireless communication system 100.

As shown in fig. 1, terminal device 116 is in communication with

antennas

112 and 114. Where

antennas

112 and 114 transmit information to terminal device 116 over a forward link (also called a downlink) 118 and receive information from terminal device 116 over a reverse link (also called an uplink) 120.

In addition, terminal device 122 is in communication with

antennas

104 and 106 transmit information to terminal device 122 over forward link 124 and receive information from terminal device 122 over reverse link 126.

For example, in a Frequency Division Duplex (FDD) system. For example, forward link 118 may use a different frequency band than reverse link 120, and forward link 124 may use a different frequency band than reverse link 126.

As another example, in Time Division Duplex (TDD) systems and full duplex (full duplex) systems, forward link 118 and reverse link 120 may utilize a common frequency band and forward link 124 and reverse link 126 may utilize a common frequency band.

Each antenna (or group of antennas consisting of multiple antennas) and/or area designed for communication is referred to as a sector of network device 102.

For example, antenna groups may be designed to communicate to terminal devices in a sector of the areas covered by network device 102. A network device may transmit signals to all terminal devices in its corresponding sector through single-antenna or multi-antenna transmit diversity. During communication by network device 102 with

terminal devices

116 and 122 over

forward links

118 and 124, respectively, the transmitting antennas of network device 102 may also utilize beamforming to improve signal-to-noise ratio of

forward links

118 and 124.

Moreover, mobile devices in neighboring cells can experience less interference when network device 102 utilizes beamforming to transmit to

terminal devices

116 and 122 scattered randomly through an associated coverage area, as compared to a manner in which the network device transmits signals to all of its terminal devices through single-antenna or multi-antenna transmit diversity.

At a given time, network device 102, terminal device 116, or terminal device 122 may be a wireless communication transmitting apparatus and/or a wireless communication receiving apparatus. When sending data, the wireless communication sending device may encode the data for transmission. Specifically, the wireless communication transmitting device may obtain (e.g., generate, receive from other communication devices, or save in memory, etc.) a number of data bits to be transmitted over the channel to the wireless communication receiving device. Such data bits may be contained in a transport block (or multiple transport blocks) of data, which may be segmented to produce multiple code blocks.

Moreover, the communication system 100 may be a PLMN network, a D2D network, an M2M network, an IoT network, or other networks, fig. 1 is a simplified schematic diagram of an example, and the communication system shown in fig. 1 may further include other network devices and/or other terminal devices, which are not shown in fig. 1 for simplicity. For example, the communication system shown in fig. 1 may be a network device communicating with a plurality of terminal devices, that is, a single network device may transmit data or control signaling to a single or a plurality of terminal devices; alternatively, the communication system shown in fig. 1 may be a plurality of network devices communicating with one terminal device, that is, a plurality of network devices may also transmit data or control signaling for a single terminal device at the same time.

It should be understood that fig. 1 is a simple schematic diagram for illustrating a scenario in which the method for interference measurement provided in the embodiment of the present application is applicable, and does not constitute any limitation to the present application.

In the following, to facilitate an understanding of the method of interference measurement provided in the embodiments of the present application, several basic concepts are first introduced.

1. The beam.

High-frequency communication can be adopted in the 5G system, namely, signals of an ultra-high frequency band (>6GHz) are adopted to transmit data. One of the main problems of high frequency communication is that signal energy drops sharply with signal transmission distance, resulting in short signal transmission distance. Therefore, the high-frequency communication adopts the analog beam technology, and the large-scale antenna array is used for weighting processing, so that the signal energy is concentrated in a smaller range to form a signal (called analog beam, beam for short) similar to a light beam, and the transmission distance is increased. The representation of a beam in the NR protocol may be a spatial domain filter, or a so-called spatial filter or spatial parameter. Specifically, a beam for transmitting a signal may be referred to as a transmission beam (Tx beam), and the Tx beam may also be referred to as a spatial domain transmission filter (spatial domain transmission filter) or a spatial transmission parameter (spatial transmission parameter); the beam used for receiving the signal may be referred to as a reception beam (Rx beam), and the Rx beam may also be referred to as a spatial domain receive filter (spatial Rx parameter) or a spatial Rx parameter.

The transmission beams may refer to signal strength distributions formed in different spatial directions after signals are transmitted by the antennas, and the reception beams may refer to signal strength distributions of wireless signals received from the antennas in different spatial directions. Further, the beam types include: wide beam, narrow beam, or other types of beams. In the existing communication system, it is specified that a beam can be formed through a beamforming technology or other technologies, where the beamforming technology may specifically be a digital beamforming technology, an analog beamforming technology, or a hybrid digital/analog beamforming technology.

Illustratively, existing protocols provide for a one-to-one correspondence between beams and resources. For example, when performing beam measurement, the quality of a beam corresponding to a certain resource may be measured by measuring a reference signal transmitted on a resource element corresponding to the resource. Similarly, when the quality of multiple beams needs to be measured, the network device may configure multiple resources corresponding to the multiple beams to the terminal device, and send a reference signal through the resource granules corresponding to the multiple resources, and the terminal device measures the reference signal and feeds back the measured quality of different resources, so that the network device knows the quality of the beams corresponding to different resources. For example, when performing data transmission, the beam information may be indicated by a resource corresponding to the beam, and specifically, the network device indicates information of a Physical Downlink Shared Channel (PDSCH) beam of the terminal device by using a Transmission Configuration Information (TCI) field in Downlink Control Information (DCI).

Illustratively, a plurality of beams having the same or similar communication characteristics may be considered as one beam. One or more antenna ports may be included in a beam for transmitting data channels, control channels, sounding signals, and the like. The one or more antenna ports forming one beam may also be seen as one set of antenna ports.

In the embodiment of the present application, a beam refers to a transmission beam of a network device, unless otherwise specified. In beam measurement, each beam of the network device corresponds to one resource, so that the beam corresponding to the resource can be uniquely identified by the index of the resource. Since there is a one-to-one correspondence between resources and beams, the following briefly introduces the concept of resources involved in the present application.

2. Resource(s)

In the beam measurement, a beam corresponding to a resource can be uniquely identified by an index of the resource. The resource may be a resource of an uplink signal or a resource of a downlink signal. Uplink signals include, but are not limited to: a Sounding Reference Signal (SRS), a demodulation reference signal (DMRS); downlink signals include, but are not limited to: a channel state information reference signal (CSI-RS), a cell specific reference signal (CS-RS), a UE specific reference signal (US-RS), a demodulation reference signal (DMRS), and a synchronization signal/physical broadcast channel block (SS/PBCH block). The SS/PBCH block may be referred to as a Synchronization Signal Block (SSB) for short.

The network device configures the resources through Radio Resource Control (RRC) signaling. In the configuration structure, a resource is a data structure including: the relevant parameters of the uplink/downlink signals corresponding to the resource, such as the type of the uplink/downlink signals, the resource granules for carrying the uplink/downlink signals, the sending time and period of the uplink/downlink signals, the number of ports used for sending the uplink/downlink signals, and the like. The resource of each uplink/downlink signal has a unique index to identify the resource of the uplink/downlink signal. It should be understood that the index of the resource may also be referred to as an identifier of the resource, and the embodiment of the present application does not limit this.

3. Beam measurement

The beam measurement is a measurement process defined in the existing protocol, and mainly comprises the following four steps:

step one, the network equipment sends measurement configuration information to the terminal equipment. The measurement configuration information is sent to the terminal device by the network device through the RRC signaling, and mainly includes two parts: resource configuration information and reporting configuration information. The resource allocation information is information related to measurement resources, and is configured by a three-level structure (resource configuration) -resource Set-resource (resource) in the protocol. The network device may configure one or more resource configurations (resourceConfig can also be written as resourceSetting) for the terminal device, each resource configuration including one or more resource sets, each resource set may include one or more resources. Each resource configuration, resource set or resource includes an index of its own. In addition, the measurement configuration information also includes some other parameters, such as the period of the resource, the signal type corresponding to the resource, and the like.

Reporting configuration information refers to reporting relevant information of a measurement result after the terminal device performs measurement, and configuring the measurement result in a protocol through reporting configuration (reportConfig). The network device may configure one or more reportconfigs for the terminal device, where each reportConfig includes information related to reporting, such as a reporting index, reporting time, a reporting period, and a reporting format. In addition, the reporting configuration further includes an index of the resource configuration, which is used to indicate what resource configuration the reported result is measured by.

Step two, the network device sends downlink signals on the resource particles corresponding to the resources configured by the resource configuration information, so that the terminal device determines the quality of each resource (beam) by measuring the downlink signals, and can also be understood as determining the quality of the beam corresponding to each resource.

And step three, the terminal equipment measures the downlink signal according to the measurement configuration information.

And step four, the terminal equipment sends a beam measurement report to the network equipment. The beam measurement report may include an index of one or more resources, a quality of the resources, and the like. Table 1 shows the reporting format used for beam measurement in the R15 protocol. The CRI (CSI-RS Index) field and the ssbri (ssb Resource Index) field are used to indicate the Resource Index to be reported. The CRI and/or SSBRI may be reported. In Table 1

And

is the length of the CRI field and SSBRI field. RSRP is the quality of the resource. The RSRP is reported by using a differential reporting criterion, that is, the RSRP of the best resource (RSRP field in table 1) is reported by using 7-bit quantization, and other RSRP (differential RSRP field in table 1) fields are reported by using 4-bit quantization.

The measurement result may be carried in a Physical Uplink Control Channel (PUCCH) or a Physical Uplink Shared Channel (PUSCH).

TABLE 1

To illustrate the beam measurement process described above, fig. 2 is a schematic diagram of a communication system 200 for performing beam measurements. Including network device 201, terminal device 202, a plurality of transmit beams, and receive beams corresponding to the transmit beams.

As shown in fig. 2, the network device 201 may generate different transmit beams pointing in different transmission directions. The specific transmit beam used for data transmission is determined by the results of the transmit beam measurements. As shown in fig. 2, first, the network device configures a plurality of measurement resources (resources for short) for the terminal device through the measurement configuration information, where each resource corresponds to one transmission beam (i.e., step one above). For each resource, the network device transmits a measurement Signal on the resource element corresponding to the resource through the transmission beam corresponding to the network device (i.e., step two above), and the terminal device receives the measurement Signal transmitted on one transmission beam through the reception beam corresponding to the transmission beam and measures the measurement Signal transmitted by each transmission beam to determine the quality of the transmission beam (resource), such as measuring the Reference Signal Receiving Power (RSRP) of each measurement Signal (i.e., step three above). By measuring the RSRP of the measurement signal corresponding to each beam, the terminal device selects one or more resources with the maximum RSRP, and reports the index of the one or more resources and the corresponding RSRP to the network device (i.e., step four above). The network device then selects one or more resources (transmit beams) from among them for data transmission.

For each transmit beam, the terminal device may further determine an optimal receive beam for receiving a signal on the transmit beam, and the determination of the receive beam is also determined through the similar beam measurement process described above, which is not limited in the application to how to determine the receive beam may be determined by multiplexing a scheme for determining the receive beam in the existing protocol, and details on the determination of the receive beam are not described below.

4. Interference is measured.

It will be appreciated that the beam measurement procedure based on RSRP of the measurement signals shown in figure 2 has a problem: the terminal device cannot feed back interference information between the transmission beams. E.g., which transmit beams have stronger interference between them. Furthermore, the network device does not know the interference between the multiple transmission beams, and when the network device transmits data to multiple terminal devices through the multiple transmission beams in the same time slot, the network device may adopt two transmission beams with strong mutual interference for transmission, which may cause data transmission errors, thereby reducing the efficiency of data transmission between the network device and the multiple terminal devices. In order to measure interference information between transmission beams, 3GPP R16 introduces measurement of layer-to-layer signal to interference and noise ratio (L1-SINR) in beam measurement, and feeds back the interference between transmission beams by measuring and reporting L1-SINR. For example, the network device configures one set of channel measurement resources { #1, #2, #3, #4} and one set of interference measurement resources { #5, #6, #7, #8}, determines channel measurement resources (e.g., resources #1 and #2) for data transmission by measuring measurement signals transmitted by transmission beams corresponding to resources in the set of channel measurement resources, and calculates L1-SINR of the channel measurement resources (e.g., resources #1 and #2) by measuring measurement signals transmitted by transmission beams corresponding to resources in the set of interference measurement resources. Optionally, the measuring interference between beams respectively corresponding to a certain channel measurement resource and a certain interference measurement resource includes: firstly, the terminal equipment receives a measuring signal sent by a sending wave beam corresponding to the channel measuring resource by adopting a receiving wave beam, and calculates first signal energy of the measuring signal; secondly, receiving a measurement signal sent by a sending wave beam corresponding to the interference measurement resource by adopting the same receiving report, and calculating second signal energy of the measurement signal; and finally, calculating the ratio of the first signal energy to the second signal energy, which is called the interference between the beams respectively corresponding to the channel measurement resource and the interference measurement resource. After the terminal equipment carries out beam quality measurement and inter-beam interference measurement, the index of the channel measurement resource and the L1-SINR of the channel measurement resource are reported to the network equipment. The L1-SINR may be calculated by using a single interference measurement resource as interference, or may be calculated by using all configured interference measurement resources as interference. For example, the L1-SINR of the channel measurement resource #1 under the interference of all interference measurement resources can be expressed as (the measurement signal energy transmitted by the beam corresponding to the resource #1 is divided by the measurement signal energy transmitted by the beam corresponding to the resources #5- # 8):

when measuring the L1-SINR of a channel measurement resource, it is necessary to measure the interference measurement resource using the receive beam of the channel measurement resource, that is, the channel measurement resource and the interference measurement resource need to be measured based on the same receive beam, so as to calculate the L1-SINR of the channel measurement resource. Therefore, when L1-SINR of a plurality of channel measurement resources needs to be measured, it is necessary to use the receiving beams corresponding to the plurality of channel measurement resources to measure the interference information measurement resources of the plurality of channel measurement resources. However, for a terminal device with poor hardware capability, generally, only a single receiving beam can be used for measurement, and if the interference measurement resource is configured only once, the terminal device can only measure L1-SINR of a single channel measurement resource, and cannot calculate L1-SINR of multiple channel measurement resources.

It should be understood that the above-mentioned reference to the signal to interference plus noise ratio by L1-SINR is only an example, and the specific english abbreviation form of the signal to interference plus noise ratio is not limited in this application. For example, L1-SINR may also be referred to as SINR, CSI-SINR, SSB-SINR, L1-CSI-SINR, L1-SSB-SINR, or the like.

The foregoing briefly introduces a scenario in which the method for interference measurement provided by the embodiments of the present application can be applied, and several basic concepts involved in the present application. In order to facilitate understanding of the beneficial effects that the method for measuring interference provided by the embodiment of the present application can bring compared with the method for measuring interference specified by the existing protocol, a method for measuring interference specified in the existing protocol is briefly described below with reference to fig. 3.

Fig. 3 is a schematic diagram of a method of interference measurement. Including a plurality of transmit beams and receive beams corresponding to the transmit beams.

The method for measuring interference shown in fig. 3 implements L1-SINR measurement of multiple channel measurement resources by configuring multiple interference measurement resource sets (which may include one or more interference measurement resources). As shown in fig. 3, the network device configures a plurality of channel measurement resources and a plurality of interference measurement resource sets for the terminal device. The number of interference measurement resource sets is equal to the number of channel measurement resources in the channel measurement resource set. The terminal device measures the resources in each interference measurement resource set by using the receiving beams of each channel measurement resource, i.e. the L1-SINR of each channel measurement resource can be calculated.

That is, the network device needs to configure multiple interference measurement resource sets for the terminal device by using the interference measurement method shown in fig. 3, where the number of the interference measurement resource sets is equal to the number of resources in the channel measurement resource set. For example, the channel measurement resource set configured by the network device for the terminal device includes 10 resources, and thus 10 interference measurement resource sets need to be configured for the terminal device, which results in a large resource overhead.

In order to solve the defects of the interference measurement method shown in fig. 3, the present application provides an interference measurement method, where the number of interference measurement resource sets configured for the terminal device by the network device is smaller than the number of channel measurement resources configured for the terminal device by the network device, so as to achieve the purpose of saving resource overhead. The method for interference measurement provided by the embodiment of the present application is described in detail below with reference to fig. 4 to 6.

Fig. 4 is a schematic diagram of an interference measurement method according to an embodiment of the present application. Including network devices, terminal devices, and S110-S140.

S110, the network equipment sends the measurement configuration information to the terminal equipment.

The measurement configuration information includes a channel measurement resource set, K interference measurement resource sets, and indication information, where the indication information is used to indicate that the number of resources in the channel measurement resource set reported by the terminal device is K, where K is a positive integer.

The channel measurement resource set configured by the network device includes M resources, where M is an integer greater than K. The M resources may belong to one or more channel measurement resource sets, that is, a channel measurement resource set in this application may refer to one channel measurement resource set or may refer to a channel measurement resource set composed of multiple channel measurement resource sets.

It should be understood that the above-mentioned indication information may be sent to the terminal device as a separate signaling, or may be carried in a signaling that is required to be sent to the terminal device by another network device, and is not limited to be carried in the above-mentioned measurement configuration information and sent to the terminal device.

It should also be understood that the present application only defines that the channel measurement resource set, the K interference measurement resource sets and the indication information are included in the measurement configuration information, but the measurement configuration information is not limited to include only the above information. For example, the measurement configuration information may further include reporting configuration information, where the reporting configuration information is used to configure information related to a measurement result sent by the terminal device to the network device.

It should also be understood that, in the present application, resources (resources in a channel measurement resource set, resources in an interference measurement resource set) correspond to beams one to one, and therefore, when the measurement resources, the quality of the resources, and the interference information of the resources are referred to throughout, they can also be described as measuring beams corresponding to the resources, the quality of beams corresponding to the resources, and the interference of beams corresponding to the resources. In the embodiments, the term "beam" is used to refer to a transmission beam without particular description.

It should also be understood that the above-mentioned channel measurement resource set includes information such as index, period, and type of each resource in the channel measurement resource set; similarly, the above-mentioned K interference measurement resource sets include information such as an index, a period, and a type of each resource included in each of the K interference measurement resource sets.

It should also be understood that, in order to better save resource overhead, the value of K may be 1, and then the network device or the protocol may specify that the terminal device only needs to report the index of 1 resource and the interference between the resource and the resource in 1 set of interference resources, where the resource is used for sending data.

Each of the K interference measurement resource sets may include at least one resource, and each resource in the interference measurement resource sets corresponds to one transmission beam; similarly, each resource in the channel measurement resource set corresponds to one transmission beam. That is to say, the quality of a measurement resource referred to in the present application may be understood as measuring the quality of a beam corresponding to the resource; and measuring interference information of a certain resource in the channel measurement resource set, which may be understood as interference between a transmission beam corresponding to the resource corresponding to the same receiving beam and a transmission beam corresponding to at least one resource in the interference measurement resource set.

For example, resource #1 in the set of channel measurement resources has the same receive beam as interference measurement resource set #1 in the K sets of interference measurement resources. The interference measurement resource set #1 includes { resource #2, resource #3, resource #4, and resource #5}, that is, the interference of resource #1 can be understood as the interference between the transmission beam corresponding to resource #1 and at least one transmission beam corresponding to at least one of resource #2, resource #3, resource #4, and resource # 5.

It will be appreciated that prior to the network device determining the resources for transmitting data, the network device will typically configure the terminal device with a set of channel measurement resources comprising M resources. The terminal device selects the K resources with better quality in the channel measurement resource set to report to the network device, that is, the network device selects the K resources with better quality to send data, that is, the number of the last resources used by the network device to send data is usually less than the number of resources included in the channel measurement resource set configured by the network device.

As can be seen from S110, in the embodiment of the present application, the number of interference measurement resource sets configured is equal to the number of resources in a channel measurement resource set reported by a terminal device, and the number of resources in the channel measurement resource set reported by the terminal device is less than the number of resources included in the channel measurement resource set configured by a network device. That is to say, in the embodiment of the present application, the number of interference measurement resource sets configured by the network device is smaller than the number of resources in the channel measurement resource set configured by the network device, so as to achieve the purpose of reducing resource overhead compared with the interference measurement method shown in fig. 3, it should be understood that, if according to the interference measurement method shown in fig. 3, the network device needs to configure M interference measurement resource sets, and by applying the interference measurement method provided in the embodiment of the present application, the overhead of M-K interference measurement resource sets is reduced.

Further, the types of the resources included in the Channel Measurement resource set in the present application may be CS-RS resources, US-RS resources, DMRS resources, SSB resources, Channel state Information-Interference Measurement (CSI-IM) resources, zero power Channel state Information reference signal (ZP CSI-RS) resources or non-zero power Channel state Information reference signal (NZP CSI-RS) resources, which are introduced in the foregoing basic concept, and may also be other types of resources, which are not listed here, and refer to the specification of the types of the resources included in the Channel Measurement resource set in the existing protocol.

Further, the resources included in the interference measurement resource set in the present application mainly refer to NZP CSI-RS resources, and in order to facilitate understanding of the resources in the interference measurement resource set, the resources included in the interference measurement resource set may be directly understood as NZP CSI-RS resources. The NZP CSI-RS resources are mainly used for measuring interference of a channel, that is, after a communication technology is developed, resources for measuring interference of a channel may not include only an interference measurement resource set with a resource type of NZP CSI-RS resources any more, and may also include other types of resources capable of being used for channel interference measurement.

It should be understood that, the present application only defines that the measurement configuration information sent by the network device needs to include the above-mentioned channel measurement resource set and K NZP CSI-RS resource sets, and is not limited to whether other resource sets are included in the measurement configuration information. For example, the measurement configuration information further includes a CSI-IM resource set, where resources included in the CSI-IM resource set are used for measuring interference of noise, and are different from the NZP CSI-RS resources used for measuring channel interference. That is, the network device may also configure one or more CSI-IM resource sets for the terminal device to measure interference of noise. In the present application, measurement of channel interference information is mainly considered, so how to configure the NZP CSI-RS resource sets and the number of the NZP CSI-RS resource sets are mainly involved, and the types and the number of other resource sets that can be configured are not limited and are not described again.

It should also be understood that, in the present application, there is no limitation on how many NZP CSI-RS resources are specifically included in the NZP CSI-RS resource set, that is, one NZP CSI-RS resource set includes at least one NZP CSI-RS resource.

It should also be understood that, in the present application, the specific implementation form of the above-mentioned resource set in the protocol is not limited, and the channel measurement resource set configured for the terminal device by the above-mentioned network device may be included in one channel measurement resource set. For example, the resource set may refer to resource sets, that is, the network device sends measurement configuration information to the terminal device, where the measurement configuration information includes one channel measurement resource set and K NZP CSI-RS resource sets, and the number of the NZP CSI-RS resource sets is equal to the number of channel measurement resource indexes in the one channel measurement resource set that needs to be reported, specifically, the K NZP CSI-RS resource sets may be configured in one resource setting, or the K NZP CSI-RS resource sets may also be configured in multiple resource settings, where a representation of the resource setting in the protocol may also be resource configuration, and a representation of the resource setting and the resource configuration in the protocol may also be replaced; for example, the resource set may refer to resource setting, that is, the network device sends measurement configuration information to the terminal device, where the measurement configuration information includes one channel measurement resource setting and K NZP CSI-RS resource setting, and the number of the NZP CSI-RS resource setting is equal to the number of channel measurement resource indexes in the one channel measurement resource setting that needs to be reported.

Specifically, in order to implement that the terminal device measures the quality of the resources in the channel measurement resource set configured by the network device, and then determines the K resources according to the measurement result, the interference information of the K resources is measured. And measuring the interference information of the K resources based on one or more resources in an interference resource set of which the K resources meet the quasi co-location as interference sources. In terms of time, the resources in the channel measurement resource set and the resources in the K interference measurement resource sets need to satisfy a certain first time relationship, for example, the first time relationship may be any one of the following cases:

X is a positive integer, and the value of X may be specified by a protocol, or may be reported by a terminal device or determined by other values reported by the terminal device.

Alternatively, the first time relationship is expressed in the form of a formula, which may be any one of the following enumerated cases:

time slot S of the last resource in time in the channel measurement resource set_CMRAnd a time slot S in which the earliest resource in time is located among all resources included in the K interference measurement resource sets_IMRThe following relationship is satisfied:

S_IMR-S_CMR>＝Th_{slot_1}

Th_{slot_1}is the first slot threshold, which is a positive integer and has the unit of a slot. Representing resources in a set of channel measurement resourcesAt least Th apart from the measurement time of all resources comprised in the set of K interference measurement resources_{slot_1}And a time slot.

Symbol F of last resource in time in channel measurement resource set_CMRAnd a symbol F in which the earliest resource in time among all resources included in the K interference measurement resource sets is located_IMRThe following relationship is satisfied:

F_IMR-F_CMR>＝Th_{symbol_1}

Th_{symbol_1}is a first sign threshold, which is a positive integer in units of signs. At least interval Th between time slot for resource in channel measurement resource set and measurement time of all resources in K interference measurement resource sets_{symbol_1}A symbol.

Time slot set S in channel measurement resource set_{CMR_set}And a time slot set S in which any one interference measurement resource set in the K interference measurement resource sets is positioned_{IMR_set}The following relationship is satisfied:

S_{IMR_set}-S_{CMR_set}>＝Th_{slot_1}

Th_{slot_1}is the first slot threshold, which is a positive integer and has the unit of a slot.

Symbol set F in channel measurement resource set_{CMR_set}And a symbol set F where any one interference measurement resource set in the K interference measurement resource sets is located_{IMR_set}The following relationship is satisfied:

F_{IMR_set}-F_{CMR_set}>＝Th_{symbol_1}

Th_{symbol_1}is a first sign threshold, which is a positive integer in units of signs.

Specifically, in order to implement that the terminal device measures interference information of K resources respectively, K interference resource sets corresponding to the K resources respectively need to satisfy a certain second time relationship, for example, the second time relationship may be any one of the following enumerated cases:

the last time slot in the time unit where the resource in the former interference measurement resource set is located in the two adjacent interference measurement resource sets in the K interference measurement resource sets in terms of time is at least Y time slots earlier than the first time slot in the time slot where the resource in the latter interference measurement resource set is located;

Y is a positive integer, and the value of Y may be specified by a protocol, or may be reported by a terminal device or determined by other values reported by the terminal device.

Alternatively, the second time relationship is expressed in the form of a formula, which may be any one of the following enumerated cases:

time slot S where the last resource in the previous interference measurement resource set in the two adjacent interference measurement resource sets in any time of the K interference measurement resource sets is located_{IMR_before}And a time slot S in which the earliest resource in time is positioned in the subsequent interference measurement resource set in the two interference measurement resource sets which are adjacent to the K interference measurement resource sets in any time_{IMR_after}The following relationship is satisfied:

S_{IMR_after}-S_{IMR_before}>＝Th_{slot_2}

Th_{slot_2}is the second slot threshold, which is a positive integer and has the unit of slot.

The last resource in the previous interference measurement resource set of two adjacent interference measurement resource sets in any time of the K interference measurement resource sets is positionedSymbol F_{IMR_before}And a symbol F in which the earliest resource in time is located in the next interference measurement resource set in the two interference measurement resource sets which are adjacent to the K interference measurement resource sets in any time_{IMR_after}The following relationship is satisfied:

F_{IMR_after}-F_{IMR_before}>＝Th_{symbol_2}

Th_{symbol_2}is a second sign threshold, which is a positive integer in sign.

Time slot set S where the former interference measurement resource set in two adjacent interference measurement resource sets in any time of K interference measurement resource sets_{IMR_before_set}And a time slot set S in which the next interference measurement resource set in the two interference measurement resource sets which are adjacent to the K interference measurement resource sets in any time is positioned_{IMR_after_set}The following relationship is satisfied:

S_{IMR_after_set}-S_{IMR_before_set}>＝Th_{slot_2}

Symbol set F where the former interference measurement resource set in two adjacent interference measurement resource sets in any time of K interference measurement resource sets is located_{IMR_before_set}And a symbol set F where the latter interference measurement resource set in the two interference measurement resource sets which are adjacent to the K interference measurement resource sets in any time is located_{IMR_after_set}The following relationship is satisfied:

F_{IMR_after_set}-F_{IMR_before_set}>＝Th_{symbol_2}

Th_{symbol_2}is a second sign threshold, which is a positive integer in units of signs.

Specifically, for a resource included in a set of periodic or semi-persistent (SP) channel measurement resources or a resource included in a set of interference measurement resources, a time relationship between the resource included in the set of channel measurement resources and the resource included in the set of interference measurement resources may be implemented by configuring a value of a parameter periodicityAndOffset; for the resources included in the aperiodic set of channel measurement resources or the resources included in the set of interference measurement resources, the time relationship between the resources included in the set of channel measurement resources and the resources included in the set of interference measurement resources may be implemented by configuring the value of the parameter aperiodictriggergingoffset. That is, the time relationship between the configured channel measurement resource set and the interference measurement resource set, the time relationship may be satisfied by configuring the parameter periodicityAndOffset or aperiodictriggergeringoffset of the channel measurement resource set and the interference measurement resource set.

It should be understood that, in this application, in order to implement that the terminal device reports the index of the K resources in the channel measurement resource set and reports the K resource interferences, the network device needs to satisfy a time relationship when configuring the above-mentioned channel measurement resource set and K interference measurement resource sets, but if the network device configures the channel measurement resource set and the interference measurement resource set for other purposes (which is not discussed in this section), the time relationship between the channel measurement resource set and the interference measurement resource set may also be that a time unit of a resource included in the interference measurement resource set is earlier than a time unit of a resource included in the channel measurement resource set in a time domain. For example, the time slot or symbol in which the last resource of the resources included in the K interference measurement resource sets is located is Q time slots or symbols earlier than the time slot or symbol in which the earliest resource of the resources included in the channel measurement resource sets is located, where Q is a positive integer.

Further, after the step S110 is executed, in order to enable the terminal device to measure the quality of the resources included in the channel measurement resource set, and determine, according to the quality measurement result of the resources in the channel measurement resource set, which K resources in the channel measurement resource set are specifically the K resources, the network device needs to send a first measurement signal to the terminal device according to the configuration of the resources in the channel measurement resource set, where the first measurement signal is used to measure the quality of the resources; further, after determining the K resources that need to be reported, the terminal device needs to measure interference information of the K resources, that is, the network device needs to send a second measurement signal to the terminal device according to the configuration of the resources of the K interference measurement resource sets, where the second measurement signal is used to measure interference information of the resources. That is, S120 is executed, the network device sends a measurement signal to the terminal device, where the measurement signal includes the first measurement signal and the second measurement signal.

The network equipment respectively sends M first measurement signals to the terminal equipment according to the configuration of each resource in the channel measurement resource set, wherein the first measurement signals are used for measuring the quality of the resource for sending the first measurement signals; the network device sends K second measurement signal sets to the terminal device according to the configuration of resources in each interference measurement resource set in the K interference measurement resource sets, and the first measurement signal and the second measurement signal set are used for measuring interference between at least one resource in the interference measurement resource set which sends the second measurement signal set and resources corresponding to the first measurement signal received by a receiving beam which receives the second measurement signal set.

Further, after performing S120, the terminal device needs to receive and measure the first measurement signal and the second measurement signal, that is, performing S130, the terminal device measures the quality of the resource and the interference information of the resource.

Specifically, the main process of the terminal device capable of measuring the quality of the resource and the interference information of the resource includes the following steps:

the method comprises the following steps: the network device sends M first measurement signals to the terminal device according to the resource allocation of M resources in the channel measurement resource set.

Step two: after receiving the M first measurement signals according to the receiving beams corresponding to the M resources, the terminal device measures the M first measurement signals respectively. For example, RSRPs of the M first measurement signals are measured, and qualities of the M resources that transmit the M first measurement signals, respectively, are determined based on the RSRPs of the M first measurement signals.

Step three: the terminal device selects the relevant information of the K resources that need to be reported to the network device in the channel measurement resource set according to the measurement results of the M first measurement signals, for example, it is determined that the relevant information of the K resources corresponding to the K first measurement signals with better quality in the M first measurement signals needs to be reported. The related information of the K resources includes an index of each resource in the K resources, RSRP of K first measurement signals corresponding to the K resources, and the like, and the index of the resource specified according to the existing protocol may be CRI or SSBRI, and it should be understood that the index of the resource in this application may also be referred to as an identifier of the resource and other names.

It should be understood that, how to determine the quality of the resource according to the first measurement signal sent on each resource in the measurement channel measurement resource set is specified in the existing protocol, which is not described herein again, and the method specified in the existing protocol may be reused for measurement.

Exemplarily, the terminal device determining which K resources of M resources included in the channel measurement resource set need to be reported may be any one of the following possibilities:

1) the terminal equipment determines the quality of each resource in the M resources according to the result of measuring the first measuring signal, and after the quality of each resource is sequentially sequenced from good to bad (no resource with the same quality), the first K resources are regarded as K resources needing to be reported.

For example, there are 10(M) resources, and the terminal device measures the first measurement signals received on the 10 resources respectively, and knows that RSRPs of the first measurement signals received on the 10 resources are 10, 9, 8, 7, 6, 5, 4, 3, 2, and 1 respectively. When the indication information indicates that the terminal device needs to report information of 5(K) resources, the terminal device reports indexes of the first 5 resources of which RSRPs of the first measurement signal are 10, 9, 8, 7, and 6, respectively, and RSRPs (10, 9, 8, 7, and 6) corresponding to the 5 resources.

2) And the terminal equipment determines the quality of each resource in the M resources according to the result of measuring the first measuring signal, and sequences the quality of each resource from good to bad in sequence, wherein when the quality of a plurality of resources is the same, the resources in the plurality of resources are at adjacent positions in the sequence after the sequence is sequenced, and the first K resources are determined as K resources needing to be reported.

For example, there are 10(M) resources, and the terminal device measures the first measurement signals received on the 10 resources respectively, and knows that RSRPs of the first measurement signals received on the 10 resources are 10, 8, 5, 4, 3, 2, and 1 respectively. When the indication information indicates that the terminal device needs to report information of 5(K) resources, the terminal device reports an index of the first 5 resources of which RSRPs of the first measurement signal are 10, 8, and 8, respectively, and RSRPs corresponding to the 5 resources (10, 8, and 8).

Step four: after the terminal device determines the K resources to be reported, K L1-SINRs corresponding to the K resources are measured. The L1-SINR of the resource may also be referred to as SINR or CQI or RSRQ of the resource.

Specifically, the network device sends K second measurement signal sets to the terminal device according to the configuration of resources in the K interference measurement resource sets. The K resources are the same as the receiving beams corresponding to the K interference measurement resource sets; or the K resources and the K interference measurement resource sets have the same TCI state; or the K resources and the K sets of interference measurement resources have the same QCL hypothesis. The QCL Type may be Type D or Type a. The K resources correspond to the K interference measurement resource sets one by one, and the terminal equipment receives a second measurement signal set sent by the interference measurement resource set corresponding to the resources by adopting a receiving wave beam for receiving a first measurement signal. The terminal device may thus calculate the quality of the K resources and calculate the interference between the K resources and at least one resource in the K interference measurement resource sets, respectively. That is, the terminal device assumes that resources in the K interference measurement resource sets are Quasi co-located (QCLed) with the K resources to be reported, respectively.

Specifically, taking one of the K resources (resource #1) as an example, the following L1-SINR calculation method can be adopted to calculate the L1-SINR of resource # 1:

wherein P is₁Is the energy, P, of the first measurement signal of resource #1_interfThe signal energy of the second measurement signal set received by using the receiving beam corresponding to the resource #1, or the signal energy of the second measurement signal set transmitted by the interference measurement resource set having the same TCI state as the resource #1, or the interference measurement resource set having the same QCL hypothesis as the resource # 1. The signal energy of the second set of measurement signals may be the signal energy of one of the second set of measurement signals, or the signal energy of the second set of measurement signals may be the sum or linear average of the signal energies of all second measurement signals comprised in the second set of measurement signals. P_otherIs other interference energy, e.g. P_otherThe energy of a third measurement signal set sent to the terminal device according to the configuration of the resource in the CSI-IM resource set, or other energy except the signal energy of a first measurement signal corresponding to the NZP CSI-RS resource set, or other energy except the signal energy of a second measurement signal corresponding to the NZP CSI-RS interference measurement resource set. It should be understood that the L1-SINR calculation may not account for P as well_other。

It should be understood that the foregoing QCL assumption may refer to an index of a resource included in QCL-info of type D included in the TCI state of the resource in the channel measurement resource set, indicating that the resource corresponds to the same receive beam as the resource indicated by the resource index included in the QCL-info.

The K resources correspond to the K interference measurement resource sets one to one, and any one of the following correspondence modes may be adopted:

1) the K interference measurement resource sets are ordered according to the measured time sequence in the time domain and correspond to the K resources one by one according to the order of the indexes from small to large or from large to small;

for example, the terminal device measures the sequence of resource sets corresponding to 5 interference measurement resource sets (interference measurement resource set #1 to interference measurement resource set #5) as interference measurement resource set #1, interference measurement resource set #3, interference measurement resource set #5, interference measurement resource set #2, and interference measurement resource set # 4; the 5 resources (resource #1 to resource #5) are sorted into resource #1 to resource #5 according to the order of the indexes from small to large, and then the K resources correspond to the K interference measurement resource sets one by one as follows:

the interference measurement resource set #1 corresponds to the resource #1, the interference measurement resource set #3 corresponds to the resource #2, the interference measurement resource set #5 corresponds to the resource #3, the interference measurement resource set #2 corresponds to the resource #4, and the interference measurement resource set #4 corresponds to the resource # 5.

2) After the K interference measurement resource sets are sorted according to the measured time sequence in the time domain, the K interference measurement resource sets are in one-to-one correspondence with the K resource sets according to the sequence configured by the network device (namely, the sequence configured by each resource in the resource sets);

for example, the terminal device measures the sequence of resource sets corresponding to 5 interference measurement resource sets (interference measurement resource set #1 to interference measurement resource set #5) as interference measurement resource set #1, interference measurement resource set #3, interference measurement resource set #5, interference measurement resource set #2, and interference measurement resource set # 4; the allocation sequence of 5 resources (resource #1 to resource #5) is resource #1, resource #3, resource #5, resource #2, and resource #4, and then the one-to-one correspondence between K resources and K interference measurement resource sets is:

the interference measurement resource set #1 corresponds to the resource #1, the interference measurement resource set #3 corresponds to the resource #3, the interference measurement resource set #5 corresponds to the resource #5, the interference measurement resource set #2 corresponds to the resource #2, and the interference measurement resource set #4 corresponds to the resource # 4.

3) After the K interference measurement resource sets are sequenced according to the measured time sequence in the time domain, the K interference measurement resource sets correspond to the K resources one by one from small to large or from large to small according to the measured resource (beam) quality (such as RSRP);

for example, the terminal device measures the sequence of resource sets corresponding to 5 interference measurement resource sets (interference measurement resource set #1 to interference measurement resource set #5) as interference measurement resource set #1, interference measurement resource set #3, interference measurement resource set #5, interference measurement resource set #2, and interference measurement resource set # 4; the quality (RSRP size) of the resources corresponding to the 5 resources (resource #1 to resource #5) is 5, 2, 4, 1, and 3, respectively, and resource # 1-resource # 3-resource # 5-resource # 2-resource #4 is obtained by sorting from large to small, and then the one-to-one correspondence between the K resources and the K interference measurement resource sets is as follows:

4) After the K interference measurement resource sets are sorted according to the measured time sequence in the time domain, the K interference measurement resource sets correspond to the K resources one to one according to the reporting (sorting required) arrangement sequence of the resources;

for example, the terminal device measures the sequence of resource sets corresponding to 5 interference measurement resource sets (interference measurement resource set #1 to interference measurement resource set #5) as interference measurement resource set #1, interference measurement resource set #3, interference measurement resource set #5, interference measurement resource set #2, and interference measurement resource set # 4; the terminal device reports 5 resources (resource #1 to resource #5) in the sequence of resource #1 to resource #3 to resource #5 to resource #2 to resource #4, and then the one-to-one correspondence between K resources and K interference measurement resource sets is:

the resource #1 corresponds to the interference measurement resource set #1, the resource #3 corresponds to the interference measurement resource set #3, the resource #5 corresponds to the interference measurement resource set #5, the resource #2 corresponds to the interference measurement resource set #2, and the resource #4 corresponds to the interference measurement resource set # 4.

5) The K interference measurement resource sets correspond to the K resources one by one according to the sequence of the indexes from large to small or from small to large and the sequence of the indexes from small to large;

for example, 5 interference measurement resource sets (interference measurement resource set #1 to interference measurement resource set # 5); the 5 resources (resource #1 to resource #5) are sorted into resource #1 to resource #5 according to the order of the indexes from small to large, and then the K resources correspond to the K interference measurement resource sets one by one as follows:

the interference measurement resource set #1 corresponds to the resource #1, the interference measurement resource set #2 corresponds to the resource #2, the interference measurement resource set #3 corresponds to the resource #3, the interference measurement resource set #4 corresponds to the resource #4, and the interference measurement resource set #5 corresponds to the resource # 5.

6) The K interference measurement resource sets correspond to the K resources one by one according to the sequence of the indexes from large to small or from small to large and the sequence configured by the network equipment (namely the sequence configured by each resource in the resource sets);

for example, 5 interference measurement resource sets (interference measurement resource set #1 to interference measurement resource set # 5); the allocation sequence of 5 resources (resource #1 to resource #5) is resource #1, resource #3, resource #5, resource #2, and resource #4, and then the one-to-one correspondence between K resources and K interference measurement resource sets is:

the interference measurement resource set #1 corresponds to the resource #1, the interference measurement resource set #2 corresponds to the resource #3, the interference measurement resource set #3 corresponds to the resource #5, the interference measurement resource set #4 corresponds to the resource #2, and the interference measurement resource set #5 corresponds to the resource # 4.

7) The K interference measurement resource sets correspond to the K resources one by one from small to large or from large to small according to the measured resource (beam) quality (such as RSRP) according to the sequence from large to small or from small to large of the indexes;

for example, 5 interference measurement resource sets (interference measurement resource set #1 to interference measurement resource set # 5); the quality (RSRP size) of the resources corresponding to the 5 resources (resource #1 to resource #5) is 5, 2, 4, 1, and 3, respectively, and resource # 1-resource # 3-resource # 5-resource # 2-resource #4 is obtained by sorting from large to small, and then the one-to-one correspondence between the K resources and the K interference measurement resource sets is as follows:

8) The K interference measurement resource sets correspond to the K resources one by one according to the sequence of the indexes from large to small or from small to large and the reporting (ordering required) arrangement sequence of the resources;

for example, 5 interference measurement resource sets (interference measurement resource set #1 to interference measurement resource set # 5); the terminal device reports 5 resources (resource #1 to resource #5) in the sequence of resource #1 to resource #3 to resource #5 to resource #2 to resource #4, and then the K resources correspond to the K interference measurement resource sets one to one as follows:

9) The K interference measurement resource sets are ordered according to the sequence configured by the network equipment (such as the sequence in the interference measurement resource set list), and are in one-to-one correspondence with the K resources after being ordered according to the sequence from small index to large index or from large index to small index;

for example, the 5 interference measurement resource sets (interference measurement resource set #1 to interference measurement resource set #5) are arranged in the order of interference measurement resource set #1, interference measurement resource set #3, interference measurement resource set #5, interference measurement resource set #2, and interference measurement resource set # 4; the 5 resources (resource #1 to resource #5) are sorted into resource #1 to resource #5 according to the order of the indexes from small to large, and then the one-to-one correspondence between the K resources and the K interference measurement resource sets is as follows:

10) The K interference measurement resource sets are ordered according to the sequence configured by the network device (for example, the sequence in the interference measurement resource set list), and correspond to the K resources one to one according to the sequence configured by the network device (that is, the sequence configured by each resource in the resource set);

for example, the 5 interference measurement resource sets (interference measurement resource set #1 to interference measurement resource set #5) are arranged in the order of interference measurement resource set #1, interference measurement resource set #3, interference measurement resource set #5, interference measurement resource set #2, and interference measurement resource set # 4; the allocation sequence of 5 resources (resource #1 to resource #5) is resource #1, resource #3, resource #5, resource #2, and resource #4, and then the one-to-one correspondence between K resources and K interference measurement resource sets is:

11) The K interference measurement resource sets are ordered according to the sequence configured by the network equipment (such as the sequence in the interference measurement resource set list), and are in one-to-one correspondence with the K resources from small to large or from large to small according to the measured resource (beam) quality (such as RSRP);

for example, the 5 interference measurement resource sets (interference measurement resource set #1 to interference measurement resource set #5) are arranged in the order of interference measurement resource set #1, interference measurement resource set #3, interference measurement resource set #5, interference measurement resource set #2, and interference measurement resource set # 4; the quality (RSRP) of the resources corresponding to the 5 resources (resource #1 to resource #5) is 5, 2, 4, 1, and 3, respectively, and resource #1 to resource #3 to resource #5 to resource #2 to resource #4 are obtained by sorting from large to small, so that the one-to-one correspondence between the K resources and the K interference measurement resource sets is as follows:

12) The K interference measurement resource sets are ordered according to the precedence order configured by the network device (for example, the precedence order in the interference measurement resource set list), and correspond to the K resources one to one according to the reporting (ordering required) arrangement order of the resources;

for example, the 5 interference measurement resource sets (interference measurement resource set #1 to interference measurement resource set #5) are arranged in the order of interference measurement resource set #1, interference measurement resource set #3, interference measurement resource set #5, interference measurement resource set #2, and interference measurement resource set # 4; the terminal device reports 5 resources (resource #1 to resource #5) in the sequence of resource #1 to resource #3 to resource #5 to resource #2 to resource #4, and then the K resources correspond to the K interference measurement resource sets one to one as follows:

Further, after the terminal device completes the above measurement, it needs to send the measurement result to the network device, i.e. S140 is executed. The measurement result is the quality information and the interference information of the K resources in the channel measurement resource set, and the interference information of the K resources may be a signal to interference plus noise ratio (SINR) of the K resources, or a Channel Quality Information (CQI) of the K resources, or a Reference Signal Received Quality (RSRQ) of the K resources, or an L1-SINR of the K resources.

Illustratively, the measurement results include: and at least one of the indexes of the K resources in the channel measurement resource set, the signal-to-noise-and-interference ratios SINR, the channel quality information CQI and the reference signal received quality RSRQ of the K resources. Further, the measurement result further includes: RSRP of the K resources, and indexes of resources in the interference measurement resource set corresponding to the K resources.

For example, the measurement configuration information further includes reporting configuration information, and specifically, the reporting configuration information is used to indicate how the terminal device performs measurement and what needs to be reported by the terminal device. Reporting configuration information in an existing protocol may be referred to as reporting configuration (reportConfig), for example, a network device may configure one or more reportconfigs for a terminal device, where each reportConfig includes reporting-related information such as a reporting index, reporting time, a reporting period, and a reporting format, where the reporting index refers to an index that needs to be reported by the terminal device, such as RSRP and/or CRI. In addition, the reporting configuration further includes an index of resource configuration (resource setting or resource Config) for indicating which resource configuration the terminal device measures, for example, the reporting configuration includes an index of the resource configuration to which the K interference measurement resource sets belong and an index of the resource configuration to which the channel measurement resource set composed of M channel measurement resources belongs; or, if the K interference measurement resource sets and the channel measurement resource set belong to one resource configuration, the reporting configuration includes the index of the resource configuration.

It should be understood that, the present application mainly relates to an improvement of a report Quantity (report Quantity) included in reporting configuration information in an existing protocol, and other parameters that need to be included in reporting configuration information specified by the existing protocol are not limited and are not described again.

Exemplarily, the report Quantity in the embodiment of the present application may be configured as at least one of the following possibilities:

1) the report quality may include a signal to interference plus noise ratio (SINR) and a resource index (cri or ssb index) without including RSRP. For example, the report Quantity is configured as ssb-Index-SINR or cri-SINR or ssb-Index-L1-SINR or cri-L1-SINR. At this time, in S140, one implementation manner of the measurement result sent by the terminal device to the network device is that the terminal device only reports the resource index and the L1-SINR corresponding to each resource.

2) The report Quantity may include SINR and RSRP, and not include a channel measurement resource index (cri or ssb index). For example, the report Quantity is configured to RSRP-SINR or SINR-RSRP. At this time, one implementation manner of the measurement result sent by the terminal device to the network device in S140 is that the terminal device only reports the L1-RSRP corresponding to each resource and the L1-SINR corresponding to each resource. The reported L1-RSRP and L1-SINR can be measured based on the same resource or different resources.

3) The report Quantity may include SINR without RSRP and resource index (cri or ssb index). For example, the report Quantity is configured to SINR or L1-SINR. At this time, one implementation manner of the measurement result sent by the terminal device to the network device in S140 is that the terminal device only reports the L1-SINR corresponding to each resource.

4) The report Quantity may include SINR, RSRP, and channel measurement resource index (cri or ssb index). For example, the report Quantity is configured as ssb-Index-RSRP-SINR or cri-RSRP-SINR or ssb-Index-SINR-RSRP or cri-SINR-RSRP. At this time, one implementation manner of the measurement result sent by the terminal device to the network device in S140 is that the terminal device reports the resource index, the RSRP corresponding to each resource, and the L1-SINR corresponding to each resource.

5) The report Quantity may include SINR and interference measurement resource Index (cri or ssb Index) (Index cri-SINR may be reported), e.g., configured as ssb-Index-SINR-interference measurement resource Index or cri-SINR-interference measurement resource Index or SINR-interference measurement resource Index. At this time, one implementation manner of the measurement result sent by the terminal device to the network device in S140 is that the terminal device reports the resource index and the L-SINR corresponding to each resource and the interference measurement resource index (for example, the index of the resource in the interference measurement resource set used for L1-SINR calculation). Another way to achieve this is that the terminal device reports the L-SINR corresponding to each resource and an interference measurement resource index (e.g., an index of a resource in an interference measurement resource set used for L1-SINR calculation), but does not report an index of a channel measurement resource. (precedence of parameters is not limiting)

6) The report Quantity may include one of SINR and interference measurement resource Index (cri or ssb Index), e.g., report Quantity is configured as ssb-Index-SINR, cri-SINR, ssb-Index-interference measurement resource Index, cri-interference measurement resource Index, ssb-Index-RSRP-SINR, cri-RSRP-SINR, ssb-Index-RSRP-interference measurement resource Index, or cri-RSRP-interference measurement resource Index. At this time, one implementation manner of the measurement result sent by the terminal device to the network device in S140 is that the terminal device reports the resource index, the L-SINR corresponding to each resource, and the interference measurement resource index (for example, an index of a resource in an interference measurement resource set used for L1-SINR calculation); another way to achieve this is that the terminal device reports the L-SINR corresponding to each resource and an interference measurement resource index (e.g., an index of a resource in an interference measurement resource set used for L1-SINR calculation), but does not report the index of the resource.

In the method flow shown in fig. 4, the network device configures a channel measurement resource set and the K interference measurement resource sets to the terminal device through the measurement configuration information, where the channel measurement resource set includes M resources, and the network device instructs the terminal device to report the K resources in the channel measurement resource set through the indication information. That is, in the method flow shown in fig. 4, the number of resources in the channel measurement resource set reported by the terminal device is equal to the number of interference measurement resource sets configured by the network device. Thus, compared with the method shown in fig. 3, the purpose of saving resources and spending is achieved. Further, in order to save more resource overhead, the network device may further configure L interference measurement resource sets, where L is a positive integer smaller than K. In the following, how the network device configures the terminal device with the channel measurement resource set and the L interference measurement resource sets is described in detail with reference to fig. 5.

Fig. 5 is a schematic diagram of another interference measurement method provided in an embodiment of the present application. Including network devices, terminal devices, and S210-S240.

S210, the network device sends first measurement configuration information to the terminal device.

The first measurement configuration information includes a channel measurement resource set, L interference measurement resource sets, and indication information, where the indication information is used to indicate that the number of resources in the channel measurement resource set reported by the terminal device is K, where K is an integer greater than 1, and L is a positive integer smaller than K.

It should be understood that the indication information may be sent to the terminal device as a separate signaling, or may be carried in a signaling that another network device needs to send to the terminal device, and is not limited to be carried in the first measurement configuration information.

It should also be understood that, in the present application, it is only limited that the first measurement configuration information includes a channel measurement resource set, L interference measurement resource sets, and indication information, but the first measurement configuration information is not limited to include only the above information, and for example, reporting configuration information may also be included, where the reporting configuration information is used to configure information about a measurement result sent by the terminal device to the network device.

It should also be understood that the above-mentioned channel measurement resource set includes information such as index, period, and type of each resource in the channel measurement resource set; similarly, the above-mentioned L interference measurement resource sets include information such as an index, a period, and a type of each resource included in each of the L interference measurement resource sets.

Each of the above-mentioned L interference measurement resource sets may include at least one resource, and each resource in the interference measurement resource set corresponds to one transmission beam; similarly, each resource in the channel measurement resource set corresponds to one transmission beam. That is, the quality of the measurement resource referred to in the present application may be understood as measuring the quality of the beam corresponding to the resource; and measuring interference information of a certain resource in the channel measurement resource set, which may be understood as interference between a transmission beam corresponding to the resource corresponding to the same receiving beam and a transmission beam corresponding to at least one resource in the interference measurement resource set.

It should be understood that before the network device determines the resources for transmitting data, the network device will generally configure the terminal device with a channel measurement resource set including M resources, where M may be an integer greater than or equal to K in the embodiment shown in fig. 5. The terminal device selects the K resources with better quality in the channel measurement resource set to report to the network device, that is, the network device selects the K resources with better quality to send data, that is, the number of the last resources used by the network device to send data is usually less than the number of resources included in the channel measurement resource set configured by the network device.

It can be seen from S210 that, in this embodiment of the present application, the number of interference measurement resource sets configured is smaller than the number of resources in a channel measurement resource set reported by a terminal device, and the number of resources in the channel measurement resource set reported by the terminal device is smaller than the number of resources included in the channel measurement resource set configured by a network device in total. That is to say, in the embodiment of the present application, the number of interference measurement resource sets configured by a network device is smaller than the number of resources in a channel measurement resource set configured by the network device, so as to achieve the purpose of reducing resource overhead compared with the method for interference measurement shown in fig. 3, it should be understood that, if the network device needs to configure M interference measurement resource sets according to the method for interference measurement shown in fig. 3, the method for interference measurement provided in the embodiment of the present application reduces the overhead of M-L interference measurement resource sets.

Further, the types of resources included in the channel measurement resource set and the types of resources included in the interference measurement resource set in the present application are similar to those described in fig. 4, and are not described herein again.

It should be understood that, the present application only limits that the above-mentioned channel measurement resource set and L NZP CSI-RS resource sets need to be included in the first measurement configuration information sent by the network device, and there is no limitation on whether other resource sets are included in the first measurement configuration information. For example, similar to the measurement configuration information described in fig. 4, the first measurement configuration information shown in fig. 5 may further include a CSI-IM resource set. For the specific description of the CSI-IM resource set, reference is made to the description of the CSI-IM resource set in fig. 4, which is not repeated herein.

It should also be understood that the specific implementation form of the resource set in the protocol is not limited in this application, and the specific possible form has been described in detail in fig. 4, and is not described herein again.

Specifically, in order to implement that the terminal device measures the quality of the resources in the channel measurement resource set configured by the network device, and then determines the K resources according to the measurement result, the terminal device measures the interference information of at least L resources in the K resources. Wherein, measuring the interference information of at least L resources in the K resources is performed based on one or more resources in an interference resource set in which the at least L resources satisfy quasi co-location as interference sources, respectively. In terms of time, the resources in the channel measurement resource set and the resources in the L interference measurement resource sets need to satisfy a certain third time relationship, for example, the third time relationship may be any one of the following cases:

the last time slot in the time slots in which the resources in the channel measurement resource set are located is at least X time slots earlier than the first time slot in the time slots in which the resources in the L interference measurement resource sets are located;

the last symbol in the symbols where the resources in the channel measurement resource set are located is at least X symbols earlier than the first symbol in the symbols where the resources in the L interference measurement resource sets are located;

the time slot set where the channel measurement resource set is located is at least X time slots earlier than any one of the L time slot sets where the L interference measurement resource sets are located;

the symbol set in which the channel measurement resource set is located is at least X symbols earlier than any one of the L symbol sets in which the L interference measurement resource sets are located.

Alternatively, the third time relationship is expressed in the form of a formula, which may be any one of the following enumerated cases:

time slot S of the last resource in time in the channel measurement resource set_CMRAnd a time slot S in which the earliest resource in time is located among all the resources included in the L interference measurement resource sets_IMRThe following relationship is satisfied:

S_IMR-S_CMR>＝Th_slot_3

Th_{slot_3}is a third time slot threshold, which is a positive integer and has a unit of time slot.

Symbol F of last resource in time in channel measurement resource set_CMRAnd a symbol F in which the earliest resource in time is located among all resources included in the L interference measurement resource sets_IMRThe following relationship is satisfied:

F_IMR-F_CMR>＝Th_{symbol_3}

Th_{symbol_3}is a third sign threshold, which is a positive integer in units of signs.

Time slot set S in channel measurement resource set_{CMR_set}And a time slot set S in which any one interference measurement resource set in the L interference measurement resource sets is positioned_{IMR_set}The following relationship is satisfied:

S_{IMR_set}-S_{CMR_set}>＝Th_{slot_3}

Th_{slot_3}is the third slot threshold, which is a positive integer and has the unit of slot.

Symbol set F in channel measurement resource set_{CMR_set}And a symbol set F in which any one interference measurement resource set in the L interference measurement resource sets is positioned_{IMR_set}The following relationship is satisfied:

F_{IMR_set}-F_{CMR_set}>＝Th_{symbol_3}

Specifically, in order to enable the terminal device to measure the interference information of at least L resources of the K resources, the L sets of interference resources need to satisfy a certain fourth time relationship, for example, the fourth time relationship may be any one of the following enumerated cases:

the last time slot in the time unit where the resource in the former interference measurement resource set is located in the two interference measurement resource sets which are adjacent to each other in time in the L interference measurement resource sets is at least Y time slots earlier than the first time slot in the time slot where the resource in the latter interference measurement resource set is located;

the last symbol in the symbol where the resource in the former interference measurement resource set is located in any two adjacent interference measurement resource sets in the L interference measurement resource sets in terms of time is at least Y symbols earlier than the first symbol in the symbol where the resource in the latter interference measurement resource set is located;

at least Y time slots are arranged between every two time slot sets in L different time slot sets where the L interference measurement resource sets are located;

at least Y symbols are arranged between every two symbol sets in L different symbol sets where the L interference measurement resource sets are located.

Alternatively, the fourth time relationship is expressed in the form of a formula, which may be any one of the following enumerated cases:

time slot S where the last resource in time in the former interference measurement resource set of two interference measurement resource sets which are adjacent to each other in time in L interference measurement resource sets in time is located_{IMR_before}And the time slot S in which the earliest resource in time is positioned in the subsequent interference measurement resource set in the two interference measurement resource sets which are randomly adjacent in time to the L interference measurement resource sets_{IMR_after}The following relationship is satisfied:

S_{IMR_after}-S_{IMR_before}>＝Th_{slot_4}

Th_{slot_4}is a fourth slot threshold, which is a positive integer and has a unit of slot.

Symbol F of last resource in time in former interference measurement resource set in two adjacent interference measurement resource sets in time of L interference measurement resource sets_{IMR_before}And a symbol F in which the earliest resource in time is located in the subsequent interference measurement resource set in two interference measurement resource sets which are adjacent to the L interference measurement resource sets in any time_{IMR_after}The following relationship is satisfied:

F_{IMR_after}-F_{IMR_before}>＝Th_{symbol_4}

Th_{symbol_4}is a fourth sign threshold, which is a positive integer in units of signs.

Time slot set S where the former interference measurement resource set in two adjacent interference measurement resource sets in any time of the L interference measurement resource sets is located_{IMR_before_set}And a time slot set S in which the next interference measurement resource set in the two interference measurement resource sets which are adjacent to the L interference measurement resource sets in any time is positioned_{IMR_after_set}The following relationship is satisfied:

S_{IMR_after_set}-S_{IMR_before_set}>＝Th_{slot_4}

Symbol set F where the former interference measurement resource set in two adjacent interference measurement resource sets in any time of L interference measurement resource sets_{IMR_before_set}And a symbol set F where the latter interference measurement resource set in the two interference measurement resource sets which are adjacent to the L interference measurement resource sets in any time is located_{IMR_after_set}The following relationship is satisfied:

F_{IMR_after_set}-F_{IMR_before_set}>＝Th_{symbol_4}

Specifically, for a resource included in a periodic or semi-persistent (SP) set of channel measurement resources or a resource included in a set of interference measurement resources, a time relationship between the resource included in the set of channel measurement resources and the resource included in the set of interference measurement resources may be achieved by configuring values of parameters periodicity and offset; for a resource included in the aperiodic set of channel measurement resources or a resource included in the set of interference measurement resources, the time relationship between the resource included in the set of channel measurement resources and the resource included in the set of interference measurement resources can be realized by configuring the value of the aperiodic triggering offset.

It should be understood that, in order to implement that the terminal device reports the index of K resources in the channel measurement resource set and reports the interference information of at least L resources in the K resources in the present application, the network device needs to satisfy a time relationship when configuring the channel measurement resource set and the L interference measurement resource sets, but if the network device configures the channel measurement resource set and the interference measurement resource set for other purposes, the time relationship between the channel measurement resource set and the interference measurement resource set may also be that a time unit in which a resource included in the interference measurement resource set is located is earlier than a time unit in which a resource included in the channel measurement resource set is located in a time domain. For example, the time slot or symbol in which the last resource of the resources included in the L interference measurement resource sets is located is y time slots or symbols earlier than the time slot or symbol in which the earliest resource of the resources included in the channel measurement resource sets is located, and y is a positive integer.

Further, after the step S210 is executed, in order to enable the terminal device to measure the quality of the resources included in the channel measurement resource set, and determine, according to the quality measurement result of the resources in the channel measurement resource set, which K resources in the channel measurement resource set specifically need to be reported, the network device needs to send a first measurement signal to the terminal device according to the configuration of the resources in the channel measurement resource set, where the first measurement signal is used to measure the quality of the resources; further, after determining the K resources that need to be reported, the terminal device needs to measure interference information of at least L resources in the K resources, that is, the network device needs to send a second measurement signal to the terminal device according to the configuration of the resources of the L interference measurement resource sets, where the second measurement signal is used to measure interference information of the resources. That is, the step S220 is executed, in which the network device sends a measurement signal to the terminal device, where the measurement signal includes the first measurement signal and the second measurement signal.

The network equipment respectively sends M first measurement signals to the terminal equipment according to the configuration of each resource in the channel measurement resource set, wherein the first measurement signals are used for measuring the quality of the resource sending the first measurement signals; the network device sends K second measurement signal sets to the terminal device according to the configuration of resources in each interference measurement resource set in the K interference measurement resource sets, and the first measurement signal and the second measurement signal set are used for measuring interference between at least one resource in the interference measurement resource set which sends the second measurement signal set and resources corresponding to the first measurement signal received by a receiving beam which receives the second measurement signal set.

Further, after performing S220, the terminal device needs to receive and measure the first measurement signal and the second measurement signal, i.e. performing S230, the terminal device measures the quality of the resource and the interference information of the resource.

Step two: and the terminal equipment respectively measures the M first measurement signals according to the M first measurement signals corresponding to the M resources. For example, RSRPs of the M first measurement signals are measured, and qualities of the M resources that transmit the M first measurement signals, respectively, are determined based on the RSRPs of the M first measurement signals.

Step four: after the terminal device determines K resources to be reported, K L1-SINRs corresponding to at least L resources in the K resources are measured. The L1-SINR of the resource may also be referred to as SINR or CQI or RSRQ of the resource. And the network equipment sends L second measurement signal sets to the terminal equipment according to the configuration of the resources in the L interference measurement resource sets.

As a possible implementation manner, when the K resources correspond to K receiving beams respectively, and the K receiving beams are different, the terminal device may calculate interference between L resources of the K resources and at least one resource of the L interference measurement resource set sets respectively. L resources in the K resources are respectively the same as the receiving wave beams corresponding to the L interference measurement resource set; or L resources of the K resources have the same TCI state as the L interference measurement resource set sets, respectively; or L resources of the K resources have the same QCL hypothesis as the L sets of interference measurement resources, respectively. The QCL Type may be Type D or Type a. The L resources correspond to the L interference resource sets one by one, and the terminal equipment receives L second measurement signal sets corresponding to the interference measurement resource set corresponding to the resource by adopting a receiving beam corresponding to a certain resource in the L resources. Thus, the terminal device can calculate the quality of the K resources and calculate the interference between L resources of the K resources and at least one resource of the L interference measurement resource sets. That is, the terminal device assumes that resources in the L interference measurement resource sets and L resources in the K resources to be reported are QCLed respectively.

For example, K is equal to 3(3 resources are resource #1 to resource #3), L is equal to 2(2 interference measurement resource sets are interference measurement resource set #1 and interference measurement resource set #2), and the terminal device determines that the related information of resource #1 and resource #2 needs to be reported to the network device according to the first measurement signal #1 to the first measurement signal #2 corresponding to the measurement resource #1 to the resource # 3. The interference measurement resource set #1 is quasi co-located with the resource #1, that is, SINR or CQI or RSRQ of the resource #1 is determined based on one or more resources in the interference measurement resource set #1 as an interference source; the quasi-co-location of the interference measurement resource set #2 with the resource #2, i.e. SINR or CQI or RSRQ of the resource #2, is determined based on one or more resources in the interference measurement resource set #2 as interference sources.

As a possible implementation manner, when multiple resources of the K resources correspond to the same receiving beam, the terminal device may calculate interference between more than L resources (P resources) of the K resources and at least one resource of the L interference measurement resource sets, where P is an integer greater than L and smaller than K. P resources in the K resources are the same as the receiving wave beams corresponding to the L interference measurement resource set sets; or P resources of the K resources and L interference measurement resource set sets have the same TCI state; or P resources of the K resources have the same QCL assumption as the L sets of interference measurement resources. The QCL Type can be Type D or Type A. The P resources correspond to the L interference measurement resource sets, at least one of the L interference measurement resource sets corresponds to a plurality of resources, and the terminal device receives a second measurement signal set corresponding to the interference measurement resource set corresponding to the plurality of resources by receiving a reception beam corresponding to the plurality of resources. Thus, the terminal device can calculate the quality of the K resources and calculate the interference between P resources of the K resources and at least one resource of the L interference measurement resource sets. That is, the terminal device assumes that resources in the L interference measurement resource sets and P resources in the K resources to be reported are QCLed, respectively.

Exemplarily, the determining, by the terminal device, L resources from the K resources may be selecting L resources with the largest resource quality (e.g., RSRP of the first measurement signal) from the K resources. As shown in table 2, assuming that L is 3, the three identified resources are resource #1, resource #2, and resource #3, and the terminal device receives three second measurement signal sets corresponding to the three interference resource sets using reception beam #1, reception beam #2, and reception beam #2, respectively.

For example, the terminal device may determine L resources from the K resources, and select the maximum L RSRPs with different receive beams from the K resources. As shown in table 2, assuming that L is 3, the three identified resources are resource #1, resource #2, and resource #4 (the reception beams of resource #2 and resource #3 are the same, and the resource quality of resource #2 is better than the quality of resource #3, so resource #3 is skipped), the terminal device receives three second measurement signal sets corresponding to the three interference resource sets using reception beam #1, reception beam #2, and reception beam #3, respectively.

The above L resources correspond to the L interference measurement resource sets one to one, and are similar to the one to one correspondence between the K resources and the K interference measurement resource sets shown in fig. 4, and are not described herein again;

the P resources correspond to the L interference measurement resource sets, and at least one of the L interference measurement resource sets corresponds to multiple resources, specifically, the one-to-one correspondence is changed into one-to-many correspondence, which is similar to the one-to-one correspondence between the K resources and the K interference measurement resource sets shown in fig. 4, and details are not repeated here.

Based on the L receiving beams determined by the L resources, or the L resources and the L interference measurement resource sets have the same TCI state, or the L resources and the L interference measurement resource sets have the same QCL assumption, and the QCL Type may be Type D or Type a. L interference measurement resource sets are respectively measured, and when L receiving beams respectively correspond to L resources, L1-SINR of the L resources can be calculated, or when the L receiving beams correspond to P resources, L1-SINR of the P channel measurement resources can be calculated.

For example, in table 2, since the reception beams corresponding to the signal resource #2 and the resource #3 are the same (reception beam #2), when the second measurement signal set corresponding to one interference measurement resource set is received using the reception beam #2, the L1-SINR of the resource #2 and the resource #3 can be calculated.

Further, after the terminal device completes the above measurement, it needs to send the measurement result to the network device, i.e. S240 is executed. The measurement result is the quality information and the interference information of the K resources in the channel measurement resource set, and the interference information of the K resources may be SINR of the K resources, or CQI of the K resources, or RSRQ of the K resources, or L1-SINR of the K resources.

As a possible implementation, the measurement result includes: and at least one of the indexes of the K resources in the channel measurement resource set, and the signal-to-noise-and-interference ratios SINR, channel quality information CQI, and reference signal received quality RSRQ of the L resources in the K resources. Further, the measurement result further includes: RSRP of K resources, interference measurement resource sets corresponding to L resources of the K resources, and the like.

As a possible implementation, the measurement result includes: and at least one of the indexes of the K resources in the channel measurement resource set, and the signal-to-noise-and-interference ratios SINRs, channel quality information CQIs, and reference signal received quality RSRQ of the P resources in the K resources. Further, the measurement result further includes: RSRP of K resources, interference measurement resource set corresponding to P resources of the K resources, and the like.

When the measured L1-SINR quantity is less than K, it means that the partial resource has no L1-SINR measurement result. At this point, one implementation is to report only the index of the resource with the L1-SINR measurement and the corresponding L1-SINR. That is, the indexes of at least L resources in the K resources and the corresponding L1-SINR are reported. Another way to achieve this is to report the measured L1-SINR (i.e., the index of the resource is reported regardless of whether there is no corresponding L1-SINR). The L1-SINR for at least L of the K resources may be reported only. All L1-SINRs measured in the above report may also be obtained, that is, when multiple resources correspond to the same receiving beam, or the multiple resources have the same TCI state, or the multiple resources have the same QCL hypothesis, one interference measurement resource set is measured through the receiving beam, or the interference measurement resource set having the same TCI state, or the interference measurement resource set having the same QCL hypothesis determines the interference measurement resource set, and L1-SINRs of the multiple resources may be calculated. And reporting all L1-SINRs when the measured L1-SINR quantity is larger than L.

The resource index and the reporting format of the L1-SINR may adopt the arrangement shown in table 3, that is, each resource is adjacent to its L1-SINR. The channel measurement resource without L1-SINR measurement (e.g., resource #3) is left empty with the corresponding L1-SINR location. When each resource is to report a plurality of L1-SINRs, the plurality of L1-SINRs are adjacent to the index of the resource in the reporting format.

Or adopting index resource index adjacent arrangement, and reporting in L1-SINR adjacent arrangement mode. The L1-SINR field corresponding to channel measurement resources without L1-SINR measurements may be filled with a special value, e.g., 0.

For example, the first measurement configuration information further includes reporting configuration information, and specifically, the reporting configuration information is used to indicate how the terminal device performs measurement and what needs to be reported by the terminal device. Reporting configuration information in an existing protocol may be referred to as report Config, for example, a network device may configure one or more report configs for a terminal device, where each report Config includes information related to reporting, such as a reporting index, reporting time, a reporting period, and a reporting format, and the reporting index refers to an index that needs to be reported by the terminal device, such as RSRP and/or CRI. In addition, the reporting configuration further includes an index of resource configuration (resource setting or resource Config) for indicating which resource configuration the terminal device measures, for example, the reporting configuration includes an index of resource configuration to which the L interference measurement resource sets belong and an index of resource configuration to which a channel measurement resource set formed by the M channel measurement resources belongs; or, if the L interference measurement resource sets and the channel measurement resource set belong to one resource configuration, the reporting configuration includes an index of the resource configuration.

For example, the report Quantity in this embodiment may be configured in any form of the report Quantity shown in fig. 4, and details thereof are not repeated here.

In the method flows shown in fig. 4 and fig. 5, the network device configures a channel measurement resource set to the terminal device through the measurement configuration information and the first measurement configuration information, where the channel measurement resource set includes M resources, and the network device instructs the terminal device to report K resources in the channel measurement resource set through the indication information. That is to say, in the method flows shown in fig. 4 and fig. 5, the terminal device needs to determine the number of resources in the reported channel measurement resource set through the indication of the network device. Further, considering that the network device may have determined, through other means, which K resources in one set of channel measurement resources are used for transmitting data, and only cannot determine interference between the K resources and other resources, the network device may directly configure the K resources and the K sets of interference measurement resources, and determine interference information of the K resources, which is described in detail below with reference to fig. 6, how the network device configures the K resources and the L sets of interference measurement resources for the terminal device.

Fig. 6 is a schematic diagram of another interference measurement method provided in an embodiment of the present application. Including network devices, terminal devices, and S310-S340.

And S310, the network equipment sends second measurement configuration information to the terminal equipment.

The second measurement configuration information includes K resources and K sets of interference measurement resources, where K is a positive integer.

It should be understood that in the embodiment shown in fig. 6, the network device knows which K resources are used for transmitting data before S310, and specifically, the network device may be determined according to the measurement results of the history terminal devices.

In the embodiment shown in fig. 6, the network device determines, through the history measurement, that resources used for sending data are the K resources, that is, when the channel measurement resource set is currently configured, the network device already knows which resources are the resources used for sending data, and when the channel measurement resource set is configured, the network device may directly configure the K resources into one channel measurement resource set and configure the K interference measurement resource sets to the terminal device.

In this implementation, the network device knows the resources used for data transmission in advance, and when the network device configures the channel measurement resource set to the terminal device, the network device does not need to configure M resources, thereby further reducing the resource overhead. For example, the network device configures 10 resources to the terminal device, the terminal device measures and reports 2 resource indexes, the network device knows that the 2 resources are used for data transmission, and only the 2 resources and 2 interference measurement resource sets need to be configured on the premise that the network device determines the 2 resources used for data transmission based on the historical measurement result, thereby reducing the overhead of interference measurement resources.

It should be understood that, in the present application, it is only limited that the second measurement configuration information includes K resources and K sets of interference measurement resources, but it is not limited that the second measurement configuration information includes only the above information, for example, reporting configuration information may also be included, where the reporting configuration information is used to configure information related to a measurement result sent by the terminal device to the network device.

Each of the K interference measurement resource sets may include at least one resource, and each resource in the interference measurement resource sets corresponds to one transmission beam; similarly, each resource in the channel measurement resource set corresponds to one transmission beam. That is, the quality of the measurement resource referred to in the present application may be understood as measuring the quality of the beam corresponding to the resource; and measuring interference information of a certain resource in the channel measurement resource set, which may be understood as interference between a transmission beam corresponding to the resource corresponding to the same receiving beam and a transmission beam corresponding to at least one resource in the interference measurement resource set.

It should be understood that, the present application only defines that the K resources and the K NZP CSI-RS resource sets need to be included in the second measurement configuration information sent by the network device, and is not limited to whether other resource sets are included in the second measurement configuration information. For example, similar to the measurement configuration information described in fig. 4, the second measurement configuration information shown in fig. 6 may further include a CSI-IM resource set. For the detailed description of the CSI-IM resource set, reference is made to the description of the CSI-IM resource set in fig. 4, which is not repeated herein.

Specifically, in order to enable the terminal device to measure the interference information of K resources respectively, the K sets of interference resources need to satisfy a certain fifth time relationship, for example, the fifth time relationship may be any one of the following enumerated cases:

the last time slot in the time unit where the resource in the former interference measurement resource set is located in the two adjacent interference measurement resource sets in the K interference measurement resource sets in terms of time is at least X time slots earlier than the first time slot in the time slot where the resource in the latter interference measurement resource set is located;

the last symbol in the symbol where the resource in the former interference measurement resource set is located in the two adjacent interference measurement resource sets in the K interference measurement resource sets in terms of time is at least X symbols earlier than the first symbol in the symbol where the resource in the latter interference measurement resource set is located;

at least X time slots are arranged between every two time slot sets in K different time slot sets where the K interference measurement resource sets are located;

at least X symbols are arranged between every two symbol sets in K different symbol sets where the K interference measurement resource sets are located.

Alternatively, the fifth time relationship is expressed in the form of a formula, which may be any one of the following enumerated cases:

time slot S of the last resource in the previous interference measurement resource set in two adjacent interference measurement resource sets in any time of K interference measurement resource sets_{IMR_before}And a time slot S in which the earliest resource in time is positioned in the subsequent interference measurement resource set in the two interference measurement resource sets which are adjacent to the K interference measurement resource sets in any time_{IMR_after}The following relationship is satisfied:

S_{IMR_after}-S_{IMR_before}>＝Th_{slot_5}

Th_{slot_5}is a fifth slot threshold, which is a positive integer and has a unit of slot.

K pieces of bean curdSymbol F of last resource in former interference measurement resource set in two interference measurement resource sets adjacent to each other in time_{IMR_before}And a symbol F in which the earliest resource in time is located in the next interference measurement resource set in the two interference measurement resource sets which are adjacent to the K interference measurement resource sets in any time_{IMR_after}The following relationship is satisfied:

F_{IMR_after}-F_{IMR_before}>＝Th_{symbol_5}

Th_{symbol_5}is a fifth sign threshold, which is a positive integer in units of signs.

S_{IMR_after_set}-S_{IMR_before_set}>＝Th_{slot_5}

F_{IMR_after_set}-F_{IMR_before_set}>＝Th_{symbol_5}

It should be understood that the network device in the embodiment shown in fig. 6 knows K resources for transmitting data, so there is no need to define the time relationship between the K resources and the above K sets of interfering resources, because the K resources are necessarily earlier in time than the above K sets of interfering resources.

Further, after performing S310, in order to enable the terminal device to measure the interference information of the K resources, the network device needs to send a measurement signal to the terminal device according to the configuration of the K resources and the resources in the K interference measurement resource sets, that is, performing S320, the network device sends a measurement signal to the terminal device, where the measurement signal includes the first measurement signal and the second measurement signal.

The network equipment respectively sends K first measurement signals to the terminal equipment according to the configuration of the K resources; the network device sends K second measurement signal sets to the terminal device according to the configuration of resources in each interference measurement resource set in the K interference measurement resource sets, and the first measurement signal and the second measurement signal set are used for measuring interference between at least one resource in the interference measurement resource set which sends the second measurement signal set and resources corresponding to the first measurement signal received by a receiving beam which receives the second measurement signal set.

Further, after performing S320, the terminal device needs to receive and measure the first measurement signal and the second measurement signal, that is, performing S330, the terminal device measures interference information of the resource.

Specifically, what the terminal device can measure the interference information of the resources may be that, after the terminal device determines K resources that need to be reported, K L1-SINRs corresponding to the K resources are measured, respectively. The L1-SINR of the resource may also be referred to as SINR or CQI or RSRQ of the resource.

Specifically, the network device sends K second measurement signal sets to the terminal device according to the configuration of resources in the K interference measurement resource sets. The K resources are the same as the receiving beams corresponding to the K interference measurement resource sets; or the K resources and the K interference measurement resource sets have the same TCI state; or the K resources and the K sets of interference measurement resources have the same QCL hypothesis. The QCL Type may be Type D or Type a. The K resources correspond to the K interference measurement resource sets one by one, and the terminal equipment receives a second measurement signal set sent by the interference measurement resource set corresponding to the resources by adopting a receiving wave beam for receiving a first measurement signal. The terminal device may thus calculate the quality of the K resources and calculate the interference between the K resources and at least one resource in the K interference measurement resource sets, respectively. That is, the terminal device assumes that resources in the K interference measurement resource sets and K resources to be reported are quasi co-located QCLed, respectively.

The K resources correspond to K sets of interference measurement resources one to one, and similar to the one shown in fig. 4, are not described one by one here.

Further, after the terminal device completes the above measurement, it needs to send the measurement result to the network device, i.e. S340 is executed. The measurement result is interference information of K resources in the above channel measurement resource set, and the interference information of K resources may be SINR of K resources, or CQI of K resources, or RSRQ of K resources, or L1-SINR of K resources.

Specifically, the L1-SINR for the terminal device to report at least K resources may be arranged and reported in a report format according to any one of the following manners:

1) the terminal equipment reports L1-SINR corresponding to the K resources according to the sequence of the K resource indexes from small to large or from large to small;

2) the terminal equipment reports L1-SINR corresponding to the K resources according to the configuration sequence of the K resources;

3) when a plurality of L1-SINRs need to be reported, the plurality of L1-SINRs are arranged from small to large or from large to small. The terminal device may also report the index of the resource in the interference measurement resource set for L1-SINR measurement.

It should be understood that, similar to that shown in fig. 5, in the method shown in fig. 6, the network device may configure L interference measurement resource sets, and specifically, interference information measured on at least L resources of the K resources based on the L interference measurement resource sets is similar to that measured on at least L resources of the K resources based on the L interference measurement resource sets in fig. 5, and is not illustrated here.

It should be understood that, in the foregoing method embodiments, the sequence numbers of the foregoing processes do not imply an order of execution, and the order of execution of the processes should be determined by functions and internal logic of the processes, and should not limit the implementation processes of the embodiments of the present application in any way.
