Description

Method and device for interference measurement

This application claims the priority of a Chinese patent application filed with the Chinese Patent Office on April 10, 2019, with the application number 201910285888.0 and the application name "Method and Apparatus for Interference Measurement", the entire content of which is incorporated into this application by reference.

Technical field

This application relates to the field of communications, and more specifically, to a method and device for interference measurement.

Background technique

High-frequency communication can be used in the fifth generation (5G) communication system, that is, ultra-high frequency band (>6GHz) signals are used to transmit data. One of the main problems of high-frequency communication is that the signal energy decreases sharply as the signal transmission distance increases, resulting in a short signal transmission distance. In order to overcome this problem, high-frequency communication uses beam technology to perform weighting processing through a large-scale antenna array to concentrate the signal energy in a small range to form a beam-like signal called beam, thereby increasing the transmission distance .

When the high-frequency communication adopts the beam technology, the network equipment can generate different transmission beams, pointing to different transmission directions. Specifically, the network device may determine which transmission beam is used to send data to the terminal device through the result of beam measurement performed by the terminal device. Among them, the basic process of beam measurement includes: first, the network device configures multiple measurement resources for measuring the quality of the transmission beam to the terminal device, and each resource corresponds to a transmission beam; secondly, the network device corresponds to each resource The transmission beam of the resource sends the measurement signal on the resource particle corresponding to the resource; then, the terminal device measures the measurement signal sent on the resource particle corresponding to each resource to determine the quality of the beam corresponding to each resource; finally, the terminal device will be able to The index of the resource corresponding to the beam used for sending data is reported to the network device. That is to say, based on the above beam measurement result, the network device determines the index of part or all of the resources from the multiple configured measurement resources, and determines that the transmission beam corresponding to the part or all of the resources can be used to send data. Further, in order to prevent the network equipment from using two transmitting beams with strong mutual interference (interference) to respectively transmit data for multiple terminal devices, it is also necessary to know the interference between the transmitting beams.

Existing communication technology provides a solution for measuring the quality of transmission beams and the interference information between the transmission beams. This solution configures multiple channel measurement resources for beam quality measurement through a network device, and the same number of channel measurement resources as the channel measurement resources. The interference measurement resource set for interference measurement, each interference measurement resource set is used to measure the interference information of one channel measurement resource, thereby measuring the interference information of all configured channel measurement resources. This solution can realize the measurement of beam interference information, but there are too many interference measurement resource sets that need to be configured, resulting in too much configuration resource overhead. Therefore, how to achieve beam quality and interference measurement with lower overhead is a problem to be solved urgently.

As shown in FIG. 1, the system 100 includes a network device 102, and the network device 102 may include one antenna or multiple antennas. For example,

antennas

104, 106, 108, 110, 112, and 114. In addition, the network device 102 may additionally include a transmitter chain and a receiver chain.

Those of ordinary skill in the art can understand that both the transmitter chain and the receiver chain may include multiple components related to signal transmission and reception (for example, a processor, modulator, multiplexer, demodulator, demultiplexer, or Antenna, etc.).

The network device 102 may communicate with terminal devices (for example, the terminal device 116 and the terminal device 122 shown in FIG. 1). However, it is understood that the network device 102 can communicate with any number of terminal devices similar to the terminal device 116 or the terminal device 122. The

terminal devices

116 and 122 may be various devices that communicate with the network device 102. For example, the terminal device 116 may be a cellular phone, a smart phone, a portable computer, a handheld communication device, a handheld computing device, a satellite radio device, a global positioning system, or a PDA. And/or any other suitable device for communicating on the wireless communication system 100.

As shown in FIG. 1, the terminal device 116 communicates with

antennas

112 and 114. Among them, the

antennas

112 and 114 transmit information to the terminal device 116 through the forward link (also referred to as the downlink) 118, and receive information from the terminal device 116 through the reverse link (also referred to as the uplink) 120.

In addition, the terminal device 122 communicates with the

antennas

104 and 106. Wherein, the

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

For example, the antenna group may be designed to communicate with terminal devices in a sector of the area covered by the network device 102. The network device can transmit signals to all terminal devices in its corresponding sector through a single antenna or multi-antenna transmit diversity. When the network device 102 communicates with the

terminal devices

116 and 122 through the

forward links

118 and 124, respectively, the transmitting antenna of the network device 102 can also use beamforming to improve the signal-to-noise ratio of the

forward links

In addition, compared with the way a network device sends signals to all of its terminal devices through a single antenna or multi-antenna transmit diversity, when the network device 102 uses beamforming to send signals to

terminal devices

116 and 122 that are randomly dispersed in the relevant coverage area, Mobile devices in neighboring cells will experience less interference.

At a given time, the network device 102, the terminal device 116, or the terminal device 122 may be a wireless communication sending device and/or a wireless communication receiving device. When sending data, the wireless communication sending device can encode the data for transmission. Specifically, the wireless communication sending device can acquire (for example, generate, receive from other communication devices, or store in a memory, etc.) a certain number of data bits to be sent to the wireless communication receiving device through a channel. Such data bits may be included in a transmission block (or multiple transmission blocks) of data, and the transmission block may be segmented to generate multiple code blocks.

In addition, the communication system 100 may be a PLMN network, a D2D network, an M2M network, an IoT network or other networks. FIG. 1 is only a simplified schematic diagram of an example. The communication system shown in FIG. 1 may also include other network devices and/or other networks. The terminal equipment is not shown in Figure 1 for simplicity. For example, the communication system shown in Figure 1 can be a network device communicating with multiple terminal devices, that is, a single network device can transmit data or control signaling to a single or multiple terminal devices; or, the communication system shown in Figure 1 It may be that multiple network devices communicate with one terminal device, that is, multiple network devices can also simultaneously transmit data or control signaling for a single terminal device.

It should be understood that FIG. 1 is only a simple schematic diagram, which is used to illustrate the applicable scenarios of the interference measurement method provided in the embodiment of the present application, and does not constitute any limitation to the present application.

Below, in order to facilitate the understanding of the interference measurement method provided in the embodiments of the present application, a few basic concepts are first introduced.

1. Beam.

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

Wherein, the transmitting beam may refer to the distribution of signal strength in different directions in space after a signal is transmitted through the antenna, and the receiving beam may refer to the signal strength distribution of the wireless signal received from the antenna in different directions in space. In addition, beam types include: wide beams, narrow beams or other types of beams. Existing communication systems stipulate that beams can be formed by beamforming technology or other technologies. The beamforming technology can specifically be digital beamforming technology, analog beamforming technology, or hybrid digital/analog beamforming technology.

Exemplarily, the existing agreement stipulates that there is a one-to-one correspondence between beams and resources. For example, when performing beam measurement, the quality of the beam corresponding to a certain resource can be measured by measuring the reference signal transmitted on the resource particle corresponding to a certain resource. Similarly, when the quality of multiple beams needs to be measured, the network device can configure multiple resources corresponding to the multiple beams to the terminal device, and send reference signals through the resource particles corresponding to the multiple resources, and the terminal device measures the reference Signals and feedback the measured quality of different resources, and the network equipment knows the quality of the beams corresponding to the different resources. For another example, when performing data transmission, the beam information can be indicated by the resource corresponding to the beam. Specifically, the network device uses the transmission configuration information (TCI) in the downlink control information (downlink control information, DCI). Field to indicate the information of the physical downlink shared channel (PDSCH) beam of the terminal device.

Exemplarily, multiple beams having the same or similar communication characteristics may be regarded as one beam. One or more antenna ports can be included in a beam for transmitting data channels, control channels, and sounding signals. One or more antenna ports forming a beam can also be regarded as an antenna port set.

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

2. Resources

In beam measurement, the resource index can be used to uniquely identify the beam corresponding to the resource. The resource can be an uplink signal resource or a downlink signal resource. Uplink signals include but are not limited to: sounding reference signal (SRS) and demodulation reference signal (DMRS); downlink signals include but are not limited to: channel state information reference signal (CSI) -RS), cell specific reference signal (cell specific reference signal, CS-RS), UE specific reference signal (user equipment specific reference signal, US-RS), demodulation reference signal (demodulation reference signal, DMRS), and synchronization signal /Physical broadcast channel block (synchronization system/physical broadcast channel block, SS/PBCH block). Among them, the SS/PBCH block may be referred to as a synchronization signal block (synchronization signal block, SSB) for short.

The network equipment configures resources through radio resource control (radio resource control, RRC) signaling. In terms of configuration structure, a resource is a data structure, including: related parameters of the uplink/downlink signal corresponding to the resource, such as the type of uplink/downlink signal, the resource element that carries the uplink/downlink signal, and the transmission time of the uplink/downlink signal Sum period, the number of ports used to transmit uplink/downlink signals, etc. Each uplink/downlink signal resource has a unique index to identify the uplink/downlink signal resource. It should be understood that the index of the resource may also be referred to as the identifier of the resource, which is not limited in the embodiment of the present application.

3. Beam measurement

Beam measurement is a measurement process defined in the existing agreement, which mainly includes the following four steps:

Step 1: The network device sends measurement configuration information to the terminal device. The measurement configuration information is sent by the network device to the terminal device through RRC signaling, and mainly includes two parts: resource configuration information and report configuration information. Resource configuration information is information related to measurement resources, and is configured in the protocol through a three-level structure (resource Config-resource Set-resource). The network device can configure one or more resource configurations for the terminal device (resource Config can also be written as resource Setting), each resource configuration includes one or more resource sets, and each resource set can include one or more resources. Each resource configuration, resource set, or resource includes its own index. In addition, the measurement configuration information also includes some other parameters, such as the period of the resource and the signal type corresponding to the resource.

Reporting configuration information means that after the terminal device performs a measurement, the measurement result reports related information, which is configured through the report Config in the protocol. The network device can configure one or more report Config for the terminal device, and each report Config includes report-related information such as report indicators, report time, report period, and report format. In addition, the report configuration also includes the resource configuration index, which is used to indicate the result of the report is measured by measuring what resource configuration.

Step 2: The network device sends a downlink signal on the resource particle corresponding to the resource configured by the resource configuration information, so that the terminal device can determine the quality of each resource (beam) by measuring the downlink signal, which can also be understood as determining the beam corresponding to each resource the quality of.

Step 3: The terminal device measures the downlink signal according to the measurement configuration information.

Step 4: The terminal device sends a beam measurement report to the network device. The beam measurement report may include the index of one or more resources, the quality of the resources, and so on. Table 1 is the report format adopted by the beam measurement in the R15 protocol. Among them, the CRI (CSI-RS Index) field and the SSBRI (SSB Resource Index) field are used to indicate the resource index to be reported. CRI and/or SSBRI can be reported. In Table 1

with

Is the length of the CRI field and the SSBRI field. RSRP is the quality of resources. RSRP reporting adopts a differential reporting criterion, that is, the best resource RSRP (RSRP field in Table 1) is reported in 7-bit quantization, while other RSRP (differential RSRP in Table 1) fields are reported in 4-bit quantization.

The above measurement results may be carried in a physical uplink control channel (PUCCH) or a physical uplink shared channel (PUSCH).

Table 1

Illustrating the foregoing beam measurement process as an example, FIG. 2 is a schematic diagram of a communication system 200 for performing beam measurement. It includes a network device 201, a terminal device 202, multiple transmitting beams, and receiving beams corresponding to the transmitting beams.

As shown in FIG. 2, the network device 201 can generate different transmission beams that point to different transmission directions. The specific transmission beam used for data transmission is determined by the result of the transmission beam measurement. As shown in FIG. 2, first, the network device configures multiple measurement resources (resources for short) for the terminal device through measurement configuration information, and each resource corresponds to a transmission beam (that is, the above step 1). For each resource, the network device transmits the measurement signal on the resource particle corresponding to the resource through its corresponding transmit beam (ie, the above step 2), and the terminal device receives the measurement sent on the transmit beam through a receive beam corresponding to the transmit beam To determine the quality of the transmission beam (resource) by measuring the measurement signal sent by each transmission beam, such as measuring the Reference Signal Receiving Power (RSRP) of each measurement signal (that is, step 3 above). By measuring the RSRP of the measurement signal corresponding to each beam, the terminal device selects one or more resources with the largest RSRP, and reports the index of the one or more resources and the corresponding RSRP to the network device (ie, step 4 above). The network device then selects one or more resources (transmit beams) from them for data transmission.

For each transmit beam, the terminal device will also determine an optimal receive beam for receiving the signal on the transmit beam. The determination of the receive beam is also determined by the above-mentioned similar beam measurement process. This application does not limit how The determination of the receiving beam may be determined by multiplexing the receiving beam determination scheme in the existing protocol, and the determination of the receiving beam will not be described in detail below.

4. Measure interference.

It should be understood that the beam measurement process based on the RSRP of the measurement signal shown in FIG. 2 has a problem: the terminal device cannot feed back the interference information between the transmission beams. For example, which transmit beams have strong interference. Furthermore, the network equipment does not know the interference between multiple transmission beams, and when the network equipment transmits data to multiple terminal devices through multiple transmission beams in the same time slot, it is possible to use two transmissions with strong mutual interference. The beam is used for transmission, resulting in data transmission errors, thereby reducing the efficiency of data transmission between network devices and multiple terminal devices. In order to measure the interference information between the transmitted beams, 3GPP R16 introduces layer 1-signal to interference plus noise ratio (L1-SINR) measurement in the beam measurement, which is fed back by measuring and reporting L1-SINR Situation of interference between transmit beams. For example, the network device configures a channel measurement resource set {#1, #2, #3, #4} and an interference measurement resource set {#5, #6, #7, #8}, and the channel measurement resource set is The measurement signal sent by the transmit beam corresponding to the resource of the, determine the channel measurement resources used for data transmission (such as resources #1 and #2), and then calculate by measuring the measurement signal sent by the transmit beam corresponding to the resource in the interference measurement resource set L1-SINR of channel measurement resources (such as resources #1 and #2). Optionally, measuring the interference between the beams corresponding to a certain channel measurement resource and a certain interference measurement resource includes: first, the terminal device uses a receiving beam to receive the measurement signal sent by the sending beam corresponding to the channel measurement resource, and calculate The first signal energy of the measurement signal; second, the same number of received reports is used to receive the measurement signal sent by the transmission beam corresponding to the interference measurement resource, and the second signal energy of the measurement signal is calculated; finally, the sum of the first signal energy is calculated The ratio of the energy of the second signal is referred to as the interference between the beams corresponding to the channel measurement resource and the interference measurement resource respectively. After the terminal device performs beam quality measurement and inter-beam interference measurement, it reports the index of the channel measurement resource and the L1-SINR of the channel measurement resource to the network device. The calculation of the L1-SINR may use a single interference measurement resource as interference, or all configured interference measurement resources may be used as interference for calculation. For example, the L1-SINR of channel measurement resource #1 under the interference of all interference measurement resources can be expressed as (the energy of the measured signal transmitted by the beam corresponding to resource #1 divided by the energy of the measured signal transmitted by the beam corresponding to resource #5-#8 with):

When measuring the L1-SINR of a channel measurement resource, the receiving beam of the channel measurement resource needs to be used to measure the interference measurement resource, that is, the channel measurement resource and the interference measurement resource need to be measured on the same receiving beam to calculate the channel measurement L1-SINR of the resource. Therefore, when the L1-SINRs of multiple channel measurement resources need to be measured, the receiving beams corresponding to the multiple channel measurement resources need to be used to measure the interference information measurement resources of the multiple channel measurement resources. However, for terminal devices with poor hardware capabilities, generally only a single receive beam can be used for measurement. If the interference measurement resource is configured only once, the terminal device can only measure the L1-SINR of a single channel measurement resource, and cannot calculate multiple channels. Measure the L1-SINR of the resource.

It should be understood that the L1-SINR used to refer to the signal-to-interference and noise ratio is only an example, and the specific English abbreviation of the signal-to-interference and noise ratio is not limited in this application. For example, L1-SINR may also be called SINR, CSI-SINR, SSB-SINR, L1-CSI-SINR or L1-SSB-SINR, etc.

The foregoing briefly introduces the applicable scenarios of the interference measurement method provided in the embodiments of this application, and several basic concepts involved in this application. In order to facilitate the understanding of the beneficial effects that the interference measurement method provided in the embodiments of this application can bring compared with the interference measurement method specified in the existing protocol, the following briefly introduces an interference measurement method specified in the existing protocol with reference to FIG. 3 .

Figure 3 is a schematic diagram of a method of interference measurement. Including multiple transmitting beams and receiving beams corresponding to the transmitting beams.

The interference measurement method shown in FIG. 3 implements L1-SINR measurement of multiple channel measurement resources by configuring multiple interference measurement resource sets (the interference measurement resource set may include one or more interference measurement resources). As shown in Figure 3, the network device configures multiple channel measurement resources and multiple 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 equipment uses the receiving beams of each channel measurement resource to measure the resources in each interference measurement resource set, and then calculates the L1-SINR of each channel measurement resource.

That is to say, the network device using the interference measurement method shown in FIG. 3 needs to configure multiple interference measurement resource sets for the terminal device, and the number of interference measurement resource sets is equal to the number of resources in the channel measurement resource set. For example, if the channel measurement resource set configured by the network device for the terminal device includes 10 resources, it is necessary to configure 10 interference measurement resource sets for the terminal device, and the resource overhead is very large.

In order to solve the shortcomings of the interference measurement method shown in FIG. 3, this application proposes an interference measurement method. The number of interference measurement resource sets configured for the terminal device through the network device is smaller than the channel configured by the network device for the terminal device. Measure the number of resources to achieve the purpose of saving resource overhead. The interference measurement method provided by the embodiment of the present application will be described in detail below in conjunction with FIG. 4 to FIG. 6.

FIG. 4 is a schematic diagram of an interference measurement method provided by an embodiment of the present application. Including network equipment, terminal equipment and S110-S140.

S110: The network device sends measurement configuration information to the terminal device.

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

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

It should be understood that the above-mentioned instruction information can be sent to the terminal device as separate signaling, or carried in the signaling that other network devices need to send to the terminal device. It is not limited to be carried in the above-mentioned measurement configuration information and sent to the terminal. equipment.

It should also be understood that this application only limits the measurement configuration information to include a channel measurement resource set, K interference measurement resource sets, and indication information, but it does not limit the measurement configuration information to only include the above information. For example, the measurement configuration information may also include reported configuration information, and the reported configuration information is used to configure related information about the measurement result sent by the terminal device to the network device.

It should also be understood that the resources (resources in the channel measurement resource set and resources in the interference measurement resource set) in this application correspond to beams one-to-one, so when the full text involves measurement resources, resource quality, and resource interference information, it can also It is described as measuring the beam corresponding to the resource, the quality of the beam corresponding to the resource, and the interference of the beam corresponding to the resource. Unless otherwise specified in the embodiment, the “beam” referred to in this application refers to a transmission beam.

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

It should also be understood that in order to better save resource overhead, the above K can be set to 1, and the network device or protocol can specify that the terminal device only needs to report the index of one resource and the resource and one interference resource set. Interference between resources, which are used to send data.

Each interference measurement resource set in the above K interference measurement resource sets may include at least one resource, and each resource in the interference measurement resource set corresponds to a transmission beam; similarly, each resource in the channel measurement resource set Corresponds to a transmit beam. In other words, the quality of the measurement resource involved in this application can be understood as measuring the quality of the beam corresponding to the resource; and the interference information of a certain resource in the measurement channel measurement resource set can be understood as corresponding to the same receiving beam The transmission beam corresponding to the resource and the interference between the transmission beam corresponding to at least one resource in the interference measurement resource set.

For example, resource #1 in the channel measurement resource set and interference measurement resource set #1 in the K interference measurement resource sets have the same receiving beam. Among them, interference measurement resource set #1 includes {resource #2, resource #3, resource #4, resource #5}, that is, the interference of resource #1 can be understood as the transmission beam corresponding to resource #1, which is similar to resource #2, Interference between at least one transmission beam corresponding to at least one of resource #3, resource #4, and resource #5.

It should be understood that, before the network device determines a resource for sending data, the network device usually configures a channel measurement resource set including M resources to the terminal device. 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 K resources with better quality to send data, that is to say, the number of resources used by the network device to send data is usually Will be less than the number of resources included in the channel measurement resource set configured by the network device.

It can be seen from S110 that the number of interference measurement resource sets configured in the embodiment of this application is equal to the number of resources in the channel measurement resource set reported by the terminal device, and the resources in the channel measurement resource set reported by the terminal device The number of is smaller than the total number of resources included in the channel measurement resource set configured by the 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 that compared with the interference measurement method shown in FIG. 3, To achieve the purpose of reducing resource overhead, it should be understood that if the interference measurement method shown in FIG. 3 is followed, the network device needs to configure M interference measurement resource sets, and the interference measurement method provided in the embodiment of this application is applied to reduce The overhead of MK interference measurement resource sets is reduced.

Further, the types of resources included in the channel measurement resource set in this application may be CS-RS resources, US-RS resources, DMRS resources, SSB resources, and channel status information interference measurement (Channel Status Information) introduced in the basic concepts above. -Interference Measurement, CSI-IM) resource, zero power channel state information reference signal (ZP CSI-RS) resource or non-zero power channel state information reference signal (none zero power channel state information reference signal) , NZP (CSI-RS) resources, etc., may also be other types of resources, which are not listed here, and can refer to the regulations on the types of resources included in the channel measurement resource set in the existing protocol.

Further, the resources included in the interference measurement resource set involved in this application mainly refer to NZP CSI-RS resources. In order to facilitate understanding of the resources in the interference measurement resource set described later in this application, the interference measurement resource set can be directly The resources included in the resource set are understood as NZP CSI-RS resources. Among them, the role of NZP CSI-RS resources is mainly used to measure channel interference, which means that after the development of communication technology, the resources for measuring channel interference may no longer only include the interference measurement of resource type NZP CSI-RS resources The resource set may also include other types of resources that can be used for channel interference measurement. This application mainly discusses NZP CSI-RS resources. Other resources that may be used for channel interference measurement are similar to NZP CSI-RS resources. Refer to the NZP CSI-RS resource configuration described in this application, which will not be repeated here.

It should be understood that this application only limits that the measurement configuration information sent by the network device needs to include the aforementioned channel measurement resource set and K NZP CSI-RS resource sets, and there is no restriction on whether the measurement configuration information includes other resource sets. For example, the aforementioned measurement configuration information also includes a CSI-IM resource set, and the resources included in the CSI-IM resource set are used for measuring noise interference, which is different from the aforementioned NZP CSI-RS resource used for measuring channel interference. In other words, the network device can also configure one or more CSI-IM resource sets for the terminal device to measure noise interference. This application mainly considers the measurement of channel interference information, so it mainly involves how to configure the NZP CSI-RS resource set and the number of NZP CSI-RS resource sets. There are no restrictions on the types and number of other resource sets that can be configured. , Do not repeat it.

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

It should also be understood that, in this application, there is no limitation on the specific embodiment of the foregoing resource set in the protocol, and the foregoing channel measurement resource set configured by the network device for the terminal device may be included in a channel measurement resource set. For example, a resource set may refer to a resource set, that is, a network device sends measurement configuration information to a terminal device. The measurement configuration information includes a channel measurement resource set and K NZP CSI-RS resource sets, and a number of NZP CSI-RS resource sets. The number is equal to the number of channel measurement resource indexes in one channel measurement resource set to be reported. Specifically, K NZP CSI-RS resource sets can be configured in one resource setting, or K NZP CSI-RS resource sets It can also be configured in multiple resource settings. Among them, the representation of resource setting in the protocol can also be resource Config, and the representations of resource setting and resource Config in the protocol can be replaced; for example, resource set can refer to resource setting, That is, the network device sends measurement configuration information to the terminal device. The measurement configuration information includes a channel measurement resource setting and K NZP CSI-RS resource settings, the number of NZP CSI-RS resource settings and a channel measurement resource setting that needs to be reported The number of channel measurement resource indexes is equal.

Specifically, in order to realize that the terminal device first measures the quality of the resources in the channel measurement resource set configured by the network device, and then measures the interference information of the K resources after determining the above K resources according to the measurement results. Wherein, measuring the interference information of the K resources is performed based on one or more resources in a set of interference resources satisfying quasi-co-location of the K resources as interference sources. In terms of time, the resources in the above-mentioned channel measurement resource set and the resources in the above-mentioned 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 situations listed below. Species:

X is a positive integer, and the value of X may be specified by the protocol, or may be reported by the 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 can be any of the following situations:

The time slot S _CMR where the last resource in time is located in the channel measurement resource set and the time slot S _IMR where the earliest one resource in time is located among all the resources included in the K interference measurement resource sets satisfy the following relationship:

S _IMR -S _CMR >=Th _{slot_1}

Th _{slot_1} is the first slot threshold, a positive integer, and the unit is a slot. It means that the time slot in which the resource in the channel measurement resource set is located is at least Th _{slot_1} time slot apart from the measurement time of all resources included in the K interference measurement resource set.

The symbol F _CMR where the last resource in time is located in the channel measurement resource set and the symbol F _IMR where the earliest resource in time is located among all the resources included in the K interference measurement resource sets satisfy the following relationship:

It means that the time slot in which the resource in the channel measurement resource set is located is at least Th _{symbol_1} symbols apart from the measurement time of all resources included in the K interference measurement resource set.

Channel resource set measurement time slot where the measured set of _S CMR_set set of resources and interfere with any of the K interference measurement resources where the set _S IMR_set slot set to satisfy the following relation:

S _{IMR_set} -S _{CMR_set} >=Th _{slot_1}

Th _{slot_1} is the first slot threshold, a positive integer, and the unit is a slot.

F _{IMR_set} -F _{CMR_set} >= Th _{symbol_1}

Th _{symbol_1} is the first symbol threshold, which is a positive integer and the unit is a symbol.

Specifically, in order to implement the terminal device to measure the interference information of K resources respectively, the K interference resource sets corresponding to the K resources need to meet a certain second time relationship, for example, the second time relationship may be as listed below Any of the situations:

The last time slot in the time unit where the resource in the previous interference measurement resource set is located in the two arbitrarily adjacent interference measurement resource sets in time of the K interference measurement resource sets is larger than the last time slot in the next interference measurement resource set. The first time slot in the time slot where the resource is located is at least Y time slots earlier;

Y is a positive integer, and the value of Y can be specified by the protocol, or can be reported by the 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 can be any of the following situations:

The time slot S _{IMR_before} where the last resource in the time slot S _{IMR_before} of the previous interference measurement resource set in the two interference measurement resource sets adjacent in time is located and the K interference measurement resource sets are in time The time slot S _{IMR_after} where the earliest one resource in the next interference measurement resource set in any two adjacent interference measurement resource sets is located satisfies the following relationship:

S _{IMR_after} -S _{IMR_before} >=Th _{slot_2}

Th _{slot_2} is the second slot threshold, a positive integer, and the unit is a slot.

K interference measurement resource sets are arbitrarily in time, the symbol F _{IMR_before} of the last interference measurement resource set in the previous interference measurement resource set in time, and the K interference measurement resource sets are arbitrary in time The symbol F _{IMR_after} of the earliest one resource in the next interference measurement resource set in two adjacent interference measurement resource sets satisfies the following relationship:

F _{IMR_after} -F _{IMR_before} >=Th _{symbol_2}

Th _{symbol_2} is the second symbol threshold, which is a positive integer and the unit is a symbol.

The time slot set S _{IMR_before_set} where the previous interference measurement resource set is located in the two interference measurement resource sets that are arbitrarily adjacent in time and the two interference measurement resource sets that are arbitrarily adjacent in time The time slot set S _{IMR_after_set} in which the next interference measurement resource set in the interference measurement resource set is located satisfies the following relationship:

S _{IMR_after_set} -S _{IMR_before_set} >=Th _{slot_2}

The symbol set F _{IMR_before_set} where the previous interference measurement resource set is located in the two interference measurement resource sets that are arbitrarily adjacent in time and the two interference measurement resource sets that are arbitrarily adjacent in time The symbol set F _{IMR_after_set} where the next interference measurement resource set in the measurement resource set is located satisfies the following relationship:

F _{IMR_after_set} -F _{IMR_before_set} >=Th _{symbol_2}

Specifically, for the resources included in the periodic or semi-persistent (semi-persistent, SP) channel measurement resource set or the resources included in the interference measurement resource set, the resources included in the channel measurement resource set can be implemented by configuring the value of the parameter periodicityAndOffset Time relationship with the resources included in the interference measurement resource set; for the resources included in the aperiodic channel measurement resource set or the resources included in the interference measurement resource set, the above-mentioned channel measurement can be implemented by configuring the value of the parameter aperiodicTriggeringOffset The time relationship between the resources included in the resource set and the resources included in the interference measurement resource set. That is, when the network device configures the time relationship between the channel measurement resource set and the interference measurement resource set, the parameter periodicityAndOffset or the aperiodicTriggeringOffset of the channel measurement resource set and the interference measurement resource set can be configured to meet the above time relationship.

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

Further, after performing the above S110, in order to enable the terminal device to measure the quality of the resources included in the channel measurement resource set, and determine the specific K resources to be reported according to the quality measurement results of the resources in the channel measurement resource set. For which K resources in the channel measurement resource set, 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, and the first measurement signal is used to measure the quality of the resource; further After determining the K resources to be reported, the terminal device also needs to measure the interference information of the K resources. That is to say, the network device needs to send the second measurement signal to the terminal device according to the resource configuration of the K interference measurement resource set , The second measurement signal is used to measure the interference information of the resource. That is to execute S120, the network device sends a measurement signal to the terminal device, and the measurement signal includes the first measurement signal and the second measurement signal described above.

The network device sends M first measurement signals to the terminal device according to the configuration of each resource in the channel measurement resource set. The first measurement signal is used to measure the quality of the resource for sending the first measurement signal; the network device sends the first measurement signal according to the K The configuration of the resources in each interference measurement resource set in the interference measurement resource set sends K second measurement signal sets to the terminal device. The first measurement signal and the second measurement signal set are used to measure the transmission of the second measurement signal set. The interference between at least one resource in the interference measurement resource set and the resource corresponding to the first measurement signal received by the receiving beam of the second measurement signal set.

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

Specifically, the main process that the terminal device can measure the quality of the resource and the interference information of the resource includes the following steps:

Step 1: The network device respectively sends M first measurement signals to the terminal device according to the resource configuration of the M resources in the channel measurement resource set.

Step 2: 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, the RSRP of the M first measurement signals are respectively measured, and the quality of the M resources for respectively sending the M first measurement signals is judged based on the RSRP of the M first measurement signals.

Step 3: The terminal device selects the K resource related information that needs 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, determines that the quality of the M first measurement signals is better The related information of the K resources corresponding to the K first measurement signals of, needs to be reported. Among them, the related information of the K resources includes the index of each of the K resources, the RSRP of the K first measurement signals corresponding to the K resources, and other related information. According to the existing protocol, the resource index may be CRI or SSBRI, it should be understood that the resource index in this application can also be referred to as resource identifier and other names.

It should be understood that the existing protocol stipulates how the terminal device determines the quality of the resource according to the first measurement signal sent on each resource in the measurement channel measurement resource set. This is not repeated in this application, and the existing protocol can be reused Perform the measurement in the prescribed method.

Exemplarily, it may be any of the following possibilities for the terminal device to determine which of the M resources included in the channel measurement resource set to report related information of which K resources:

1) The terminal device determines the quality of each of the M resources according to the result of measuring the first measurement signal, and ranks the quality of each resource from good to bad (there is no resource with the same quality), and then ranks in the top K Of resources are identified as K resources to be reported.

For example, there are a total of 10 (M) resources. The terminal device measures the first measurement signal received on the 10 resources, and learns that the RSRP of the first measurement signal received on the 10 resources is 10, 9, and respectively. 8, 7, 6, 5, 4, 3, 2, 1. When the above-mentioned indication information indicates that the terminal device needs to report information about 5 (K) resources, the RSRP of the first measurement signal reported by the terminal device is the index of the first 5 resources of 10, 9, 8, 7, and 6, respectively. RSRP (10, 9, 8, 7, 6) corresponding to 5 resources.

2) The terminal device determines the quality of each of the M resources according to the result of measuring the first measurement signal, and sorts the quality of each resource from good to bad. When the quality of multiple resources is the same, the multiple resources The resources in are in adjacent positions in the sequence after sorting, and the top K resources are identified as K resources to be reported.

For example, there are a total of 10 (M) resources, and the terminal device measures the first measurement signal received on the 10 resources, and learns that the RSRP of the first measurement signal received on the 10 resources is 10, 10, and 10, respectively. 10, 8, 8, 5, 4, 3, 2, 1. When the above-mentioned indication information indicates that the terminal device needs to report information about 5 (K) resources, the RSRP of the first measurement signal reported by the terminal device is the index of the first 5 resources of 10, 10, 10, 8, and 8, respectively. RSRP (10, 10, 10, 8, 8) corresponding to 5 resources.

Step 4: After the terminal device determines the K resources to be reported, it measures the K L1-SINRs corresponding to the K resources. Among them, the L1-SINR of the resource may also be referred to as the 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 the resources in the K interference measurement resource sets. The above 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 interference measurement resource sets have the same TCI state Have the same QCL assumptions. The QCL type can be Type D or Type A. The K resources are in one-to-one correspondence with the K interference measurement resource sets, and the terminal device uses the receiving beam for receiving the first measurement signal to receive the second measurement signal set sent by the interference measurement resource set corresponding to the resource. Therefore, the terminal device can 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. That is, the terminal device assumes that the resources in the K interference measurement resource sets are quasi-colocated (QCLed) respectively with the K resources to be reported.

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

Where P ₁ is the energy of the first measurement signal of resource #1, and P _interf is the signal energy of the second measurement signal set received by the receiving beam corresponding to resource #1, or the energy of the second measurement signal set that has the same TCI state as resource #1 The interference measurement resource set, or the signal energy of the second measurement signal set sent by the interference measurement resource set with the same QCL assumption as resource #1. The signal energy of the second measurement signal set may be the signal energy of a second measurement signal in the second measurement signal set, or the signal energy of the second measurement signal set may be all the first measurement signals included in the second measurement signal set. 2. The sum or linear average of the signal energy of the measurement signal. P _other is other interference energy, for example, P _other is the CSI-IM resource set configured by the network device, and the signal energy of the third measurement signal set sent to the terminal device according to the resource configuration in the CSI-IM resource set, or NZP Energy other than the signal energy of the first measurement signal corresponding to the CSI-RS resource set, or energy other than the signal energy of the second measurement signal corresponding to the NZP CSI-RS interference measurement resource set. It should be understood that the calculation of L1-SINR may not be included in P _other .

It should be understood that the above QCL assumption may refer to the index of the resource included in the QCL-info of type D included in the TCI state of the resource in the channel measurement resource set, indicating that the resource and the resource index indication included in the QCL-info The resources correspond to the same receiving beam.

Further, after the terminal device completes the above measurement, it needs to send the measurement result to the network device, that is, execute S140. Among them, the measurement result is the quality information and interference information of the K resources in the above-mentioned channel measurement resource set, and the interference information of the K resources may be the signal to interference plus noise ratio of the K resources. , SINR), or channel quality information (channel quantity information, CQI) of K resources, or reference signal received quality (RSRQ) of K resources, or L1-SINR of K resources.

Exemplarily, the measurement result includes: the index of the K resources in the channel measurement resource set and at least one of the signal-to-noise-to-interference ratio SINR of the K resources, the channel quality information CQI, and the reference signal reception quality RSRQ. Further, the measurement result also includes information such as RSRP of K resources and an index of resources in the interference measurement resource set corresponding to the K resources.

Exemplarily, the above-mentioned measurement configuration information further includes report configuration information. Specifically, the report 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 existing protocols can be called report Config. For example, a network device can configure one or more report Configs for a terminal device. Each report Config includes reporting indicators, reporting time, reporting period, and Reporting format and other information related to reporting, where the reporting index refers to the index that needs to be reported by the terminal device, such as RSRP and/or CRI. In addition, the reported configuration also includes an index of resource configuration (resource setting or resource Config), which is used to indicate which resource configuration the terminal device measures. For example, the reported configuration in this application includes the resource configuration of the K interference measurement resource sets mentioned above. And the 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 set and the channel measurement resource set belong to one resource configuration, the report configuration includes the resource configuration index.

It should be understood that this application mainly involves the improvement of the report Quantity included in the reported configuration information in the existing protocol, and there is no restriction on other parameters that need to be included in the reported configuration information specified in the existing protocol, and will not be repeated .

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

1) The report Quantity may include signal to interference plus noise ratio (SINR) and resource index (cri or ssb index) but not 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, one implementation of the measurement result sent by the terminal device to the network device in S140 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, but not the channel measurement resource index (cri or ssb index). For example, the report Quantity is configured as RSRP-SINR or SINR-RSRP. At this time, one implementation 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 based on different resources.

3) The report Quantity may include SINR but not RSRP and resource index (cri or ssb index). For example, the report Quantity is configured as 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 and the RSRP corresponding to each resource and the L1-SINR corresponding to each resource.

5) Report Quantity can include SINR and interference measurement resource index (cri or ssb index) (index cri-SINR can be reported), for example, 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 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, used for L1-SINR calculation) The index of the resource in the interference measurement resource set). Another implementation is that the terminal device reports 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), instead of reporting the channel measurement resource index of. (The sequence of parameters is not limited)

6) Report Quantity can include one of SINR and interference measurement resource index (cri or ssb index). For example, 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 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, used for L1-SINR calculation) The index of the resource in the interference measurement resource set); another implementation is that the terminal device reports the L-SINR corresponding to each resource and the interference measurement resource index (for example, the resource in the interference measurement resource set used for L1-SINR calculation) Index) instead of reporting the resource index.

In the method flow shown in FIG. 4, the network device configures the channel measurement resource set and the K interference measurement resource sets to the terminal device through measurement configuration information, the channel measurement resource set includes M resources, and the network device instructs The information indicates that the terminal device reports K resources in the channel measurement resource set. 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. Therefore, compared with the method shown in FIG. 3 according to the process, the purpose of saving resources and expenses is achieved. Further, in order to further save resource overhead, the network device may also configure L interference measurement resource sets, and L is a positive integer less than K. The following describes in detail in conjunction with FIG. 5, how the network device configures the channel measurement resource set and L interference measurement resource sets for the terminal device.

Fig. 5 is a schematic diagram of another interference measurement method provided by an embodiment of the present application. Including network equipment, terminal equipment 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. The indication information is used to instruct the terminal device to report that the number of resources in the channel measurement resource set is K, where: K is an integer greater than 1, and L is a positive integer less than K.

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

It should also be understood that this application only limits the first measurement configuration information to include a channel measurement resource set, L interference measurement resource sets and indication information, but it does not limit the first measurement configuration information to only include the above-mentioned information. For example, It includes reported configuration information, which is used to configure related information about the measurement results sent by the terminal device to the network device.

It should also be understood that the foregoing channel measurement resource set includes information such as the index, period, and type of each resource in the channel measurement resource set; similarly, the foregoing L interference measurement resource sets include the L interferences. Information such as the index, period, and type of each resource included in each interference measurement resource set in the measurement resource set.

Each interference measurement resource set in the foregoing L interference measurement resource sets may include at least one resource, and each resource in the interference measurement resource set corresponds to a transmission beam; similarly, each resource in the channel measurement resource set Corresponds to a transmit beam. In other words, the quality of the measurement resource involved in this application can be understood as measuring the quality of the beam corresponding to the resource; and the interference information of a certain resource in the measurement channel measurement resource set can be understood as corresponding to the same receiving beam The transmission beam corresponding to the resource and the interference between the 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 resource for sending data, the network device usually configures a channel measurement resource set including M resources to the terminal device. In the embodiment shown in FIG. 5, M may be greater than or equal to K. Integer. The terminal device selects K resources with better quality in the channel measurement resource set and reports to the network device, that is, the network device selects K resources with better quality to send data, that is to say, the number of resources used by the network device to send data will usually be It is 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 the number of interference measurement resource sets configured in the embodiment of this application is less than the number of resources in the channel measurement resource set reported by the terminal device, and the resources in the channel measurement resource set reported by the terminal device The number of is smaller than the total number of resources included in the channel measurement resource set configured by the 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 that compared with the interference measurement method shown in FIG. 3, To achieve the purpose of reducing resource overhead, it should be understood that if the interference measurement method shown in FIG. 3 is followed, the network device needs to configure M interference measurement resource sets, and the interference measurement method provided in the embodiment of this application is applied to reduce The overhead of ML interference measurement resource sets is reduced.

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 this application are similar to those described in FIG. 4, and will not be repeated here.

It should be understood that this application only limits that the first measurement configuration information sent by the network device needs to include the aforementioned channel measurement resource set and L NZP CSI-RS resource sets, and it does not matter whether the first measurement configuration information includes other resource sets. limit. For example, similar to the measurement configuration information described in FIG. 4, the first measurement configuration information shown in FIG. 5 may also include a CSI-IM resource set. For the specific description of the CSI-IM resource set, refer to the description of the CSI-IM resource set in FIG. 4, which will not be repeated here.

It should also be understood that this application does not limit the specific manifestation of the above-mentioned resource set in the protocol, and the specific possible form has been described in detail in FIG. 4, and will not be repeated here.

Specifically, in order to realize that the terminal device first measures the quality of the resources in the channel measurement resource set configured by the network device, and then determines the above K resources according to the measurement results, then measures at least L of the K resources Interference information. Wherein, measuring the interference information of at least L of the K resources is performed based on one or more resources in the set of interference resources whose at least L resources satisfy quasi-colocation as interference sources. In terms of time, the resources in the foregoing channel measurement resource set and the resources in the foregoing 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 situations listed below. Species:

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

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

The time slot set in which the channel measurement resource set is located is at least X time slots earlier than any one of the L time slot sets in which 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 symbol set in 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 can be any of the following situations:

The time slot S _CMR where the last resource in time is located in the channel measurement resource set and the time slot S _IMR where the earliest resource in time is located among all the resources included in the L interference measurement resource sets satisfy the following relationship:

S _IMR -S _CMR >=Th _{slot_3}

Th _{slot_3} is the third slot threshold, a positive integer, and the unit is a slot.

The symbol F _CMR where the last resource in time is located in the channel measurement resource set and the symbol F _IMR where the earliest resource in time is located among all the resources included in the L interference measurement resource sets satisfy the following relationship:

F _IMR -F _CMR >= Th _{symbol_3}

Th _{symbol_3} is the third symbol threshold, which is a positive integer and the unit is a symbol.

Channel resource set measurement time slot where the measured set of _S CMR_set set of resources and interfere with any one of the L interference measurement resources where the set _S IMR_set slot set to satisfy the following relation:

S _{IMR_set} -S _{CMR_set} >=Th _{slot_3}

Measuring channel symbols where the resource set and a set of the L _F CMR_set interference measurement resource set to any one interfering symbol set _F IMR_set measurement set where resources satisfy the following relationship:

F _{IMR_set} -F _{CMR_set} >= Th _{symbol_3}

Specifically, in order to realize that the terminal device separately measures the interference information of at least L resources among the K resources, the set of L interference resources needs to satisfy a certain fourth time relationship, for example, the fourth time relationship may be the following cases Any of:

The last time slot in the time unit where the resource in the previous interference measurement resource set is located in the two arbitrarily adjacent interference measurement resource sets in time for the L interference measurement resource sets is larger than the last time slot in the next interference measurement resource set. The first time slot in the time slot where the resource is located is at least Y time slots earlier;

The last symbol in the symbol where the resource in the previous interference measurement resource set is located in the two arbitrarily adjacent interference measurement resource sets in time of the L interference measurement resource sets is shorter than the resource in the next interference measurement resource set. The first symbol in the symbols is at least Y symbols earlier;

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

In the L different symbol sets where the L interference measurement resource sets are located, at least Y symbols are spaced between every two symbol sets.

Alternatively, the fourth time relationship is expressed in the form of a formula, which can be any of the following situations:

The L interference measurement resource sets are arbitrarily adjacent in time in the previous interference measurement resource set in the previous interference measurement resource set, the time slot S _{IMR_before} where the last resource in time is located and the L interference measurement resource sets are in time The time slot S _{IMR_after} where the earliest one resource in the next interference measurement resource set in any two adjacent interference measurement resource sets is located satisfies the following relationship:

S _{IMR_after} -S _{IMR_before} >=Th _{slot_4}

Th _{slot_4} is the fourth slot threshold, a positive integer, and the unit is a slot.

L interference measurement resource sets are arbitrarily adjacent in time in the previous interference measurement resource set in the previous interference measurement resource set, the symbol F _{IMR_before} where the last resource in time is located and the L interference measurement resource sets are arbitrary in time The symbol F _{IMR_after} of the earliest one resource in the next interference measurement resource set in two adjacent interference measurement resource sets satisfies the following relationship:

F _{IMR_after} -F _{IMR_before} >= Th _{symbol_4}

Th _{symbol_4} is the fourth symbol threshold, which is a positive integer and the unit is a symbol.

S _{IMR_after_set} -S _{IMR_before_set} >=Th _{slot_4}

F _{IMR_after_set} -F _{IMR_before_set} >=Th _{symbol_4}

Specifically, for the resources included in the periodic or semi-persistent (semi-persistent, SP) channel measurement resource set or the resources included in the interference measurement resource set, the channel measurement resource set can be included in the channel measurement resource set by configuring the value of the parameter periodicity and offset. The time relationship between the resources and the resources included in the interference measurement resource set; for the resources included in the aperiodic channel measurement resource set or the resources included in the interference measurement resource set, you can configure the parameter aperiodic triggering offset To realize the time relationship between the resources included in the channel measurement resource set and the resources included in the interference measurement resource set.

It should be understood that, in this application, in order to enable the terminal device to report the index of the K resources in the channel measurement resource set and report the interference information of at least L resources in the K resources, the network device configures the channel measurement resource set and L When a set of interference measurement resources, the time relationship needs to be satisfied, 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 can still be Yes, the time unit of the resource included in the interference measurement resource set is earlier than the time of the resource included in the channel measurement resource set in the time domain. For example, in the time domain, the time slot or symbol of the last resource of the resources included in the L interference measurement resource sets is y time slots or symbols earlier than the time slot or symbol of the earliest resource included in the channel measurement resource set. y is a positive integer.

Further, after performing the above-mentioned S210, in order to enable the terminal device to measure the quality of the resources included in the above-mentioned channel measurement resource set, and determine the specific K resources that need to be reported according to the quality measurement results of the resources in the channel measurement resource set. For which K resources in the channel measurement resource set, 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, and the first measurement signal is used to measure the quality of the resource; further After determining the K resources that need to be reported, the terminal device also needs to measure the interference information of at least L of the K resources. That is to say, the network device needs to report to the terminal device according to the resource configuration of the L interference measurement resource set. Send a second measurement signal, where the second measurement signal is used to measure the interference information of the resource. That is to execute S220, the network device sends a measurement signal to the terminal device, and the measurement signal includes the first measurement signal and the second measurement signal described above.

Further, after performing S220, the terminal device needs to receive and measure the above-mentioned first measurement signal and the second measurement signal, that is, perform S230, and the terminal device measures the quality of the resource and the interference information of the resource.

Step 2: After the terminal device measures the M first measurement signals according to the M first measurement signals corresponding to the M resources, respectively. For example, the RSRP of the M first measurement signals are respectively measured, and the quality of the M resources for respectively sending the M first measurement signals is judged based on the RSRP of the M first measurement signals.

Step 4: After the terminal device determines the K resources to be reported, the K L1-SINRs corresponding to at least L of the K resources are measured. Among them, the L1-SINR of the resource may also be referred to as the SINR or CQI or RSRQ of the resource. The network device sends L second measurement signal sets to the terminal device according to the configuration of the resources in the L interference measurement resource sets.

As a possible implementation, when K resources correspond to K receive beams, and the K receive beams are different, the terminal device can calculate that L of the K resources are different from the set of L interference measurement resources. Interference between at least one resource. The L resources in the K resources are respectively the same as the receiving beams corresponding to the L interference measurement resource sets; in other words, the L resources in the K resources have the same TCI state as the L interference measurement resource sets; or The L resources among the K resources respectively have the same QCL hypothesis as the L interference measurement resource set sets. The QCL type can be Type D or Type A. The L resources are in one-to-one correspondence with the L interference resource sets, and the terminal device uses a receiving beam corresponding to a certain resource among the L resources to receive the L second measurement signal sets corresponding to the interference measurement resource set corresponding to the resource. Therefore, the terminal device can calculate the quality of the K resources, and calculate the interference between the L resources in the K resources and at least one resource in the set of L interference measurement resources. That is, the terminal device assumes that the resources in the L interference measurement resource sets and the L resources in the K resources to be reported are QCLed.

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

As a possible implementation, when multiple resources in the K resources correspond to the same receiving beam, the terminal device can calculate that more than L resources (P resources) among the K resources and L interference measurement For interference between at least one resource in the resource set, P is an integer greater than L and less than K. P resources in K resources are the same as the receiving beams corresponding to L interference measurement resource sets; or P resources in K resources and L interference measurement resource sets have the same TCI state; or K The P resources in the resources and the L interference measurement resource sets have the same QCL hypothesis. The QCL type can be Type D or Type A. The P resources correspond to the L interference measurement resource sets, at least one interference measurement resource set in the L interference measurement resource sets corresponds to multiple resources, and the terminal device receives the receiving beams corresponding to the multiple resources to receive the multiple resources The second measurement signal set corresponding to the corresponding interference measurement resource set. Therefore, the terminal device can calculate the quality of the K resources, and calculate the interference between the P resources in the K resources and at least one resource in the set of L interference measurement resources. That is, the terminal device assumes that the resources in the L interference measurement resource sets and the P resources among the K resources to be reported are QCLed.

Exemplarily, the foregoing terminal device determining the L resources from the K resources may be selecting the L resources with the largest resource quality (for example, the RSRP of the first measurement signal) among the K resources. As shown in Table 2, assuming L=3, the three determined resources are resource #1, resource #2, and resource #3. The terminal device uses receiving beam #1, receiving beam #2, and receiving beam #2 to receive the three resources respectively. Three sets of second measurement signals corresponding to two sets of interference resources.

Exemplarily, the foregoing terminal device determining the L resources from the K resources may be selected to receive the largest resources of the L RSRPs with different beams among the K resources. As shown in Table 2, assuming L=3, the three determined resources are resource #1, resource #2, and resource #4 (receive beams of resource #2 and resource #3 are the same and the resource quality ratio of resource #2 The quality of resource #3 is good, so resource #3 is skipped), and the terminal equipment uses receiving beam #1, receiving beam #2, and receiving beam #3 to respectively receive the three second measurement signal sets corresponding to the three interference resource sets .

The foregoing L resources correspond to L interference measurement resource sets one-to-one, which is similar to the one-to-one correspondence between K resources and K interference measurement resource sets shown in FIG. 4, and will not be repeated here;

The foregoing P resources correspond to L interference measurement resource sets. At least one interference measurement resource set in the L interference measurement resource sets may correspond to multiple resources. Specifically, the above-mentioned one-to-one correspondence is changed to one-to-many. , Which is similar to the one-to-one correspondence between K resources and K interference measurement resource sets shown in FIG. 4, and will not be repeated here.

L receiving beams determined based on L resources, or L resources and L interference measurement resource sets have the same TCI state, or L resources and L interference measurement resource sets have the same QCL assumption, QCL type It can be Type D or Type A. Measure L interference measurement resource sets separately. When L receive beams correspond to L resources, the L1-SINR of L resources can be calculated, or when L receive beams correspond to P resources, P can be calculated. L1-SINR of each channel measurement resource.

For example, in Table 2, the receiving beams corresponding to resource #2 and resource #3 are the same (receiving beam #2), so when receiving beam #2 is used to receive the second measurement signal set corresponding to an interference measurement resource set, you can Calculate the L1-SINR of resource #2 and resource #3.

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

As a possible implementation, the measurement result includes: the index of the K resources in the channel measurement resource set and the signal-to-noise-to-interference ratio SINR of the L resources in the K resources, the channel quality information CQI, and the reference signal reception quality RSRQ At least one of them. Further, the measurement result also includes information such as RSRP of K resources, and an interference measurement resource set corresponding to L of the K resources.

As a possible implementation, the measurement result includes: the index of the K resources in the channel measurement resource set and the signal-to-noise-to-interference ratio SINR of the P resources among the K resources, the channel quality information CQI, and the reference signal reception quality RSRQ At least one of them. Further, the measurement result also includes information such as RSRP of K resources, and interference measurement resource sets corresponding to P resources among the K resources.

When the number of L1-SINR measured is less than K, it means that some resources have no L1-SINR measurement result. At this time, one implementation is to report only the index of the resource with the L1-SINR measurement result and the corresponding L1-SINR. That is, the indexes of at least L resources among the K resources and the corresponding L1-SINR are reported. Another implementation is to report the measured L1-SINR (that is, report the index of the resource regardless of whether there is a corresponding L1-SINR). It is possible to report only the L1-SINR of at least L of the K resources. It is also possible to report all L1-SINR measured, 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, the receiving For beam measurement, an interference measurement resource set, or an interference measurement resource set with the same TCI state, or an interference measurement resource set with the same QCL assumption is determined to determine an interference measurement resource set, and L1-SINRs of multiple resources can be calculated. At this time, the number of L1-SINR measured is greater than L, and all L1-SINRs are reported.

The reporting format of the resource index and L1-SINR can adopt the arrangement shown in Table 3, that is, each resource is adjacent to its L1-SINR. The corresponding L1-SINR position behind the channel measurement resource (such as resource #3) without the L1-SINR measurement result is left blank. When multiple L1-SINRs are to be reported for each resource, the multiple L1-SINRs and the index of the resource are adjacent in the reporting format.

The index resource index may also be arranged adjacently, and all L1-SINRs may be arranged adjacently for reporting. The L1-SINR field corresponding to the channel measurement resource without the L1-SINR measurement result can be filled with a special value, such as 0.

Exemplarily, the above-mentioned first measurement configuration information further includes report configuration information. Specifically, the report configuration information is used to indicate how the terminal device performs measurement and what needs to be reported by the terminal device. The configuration information reported in the existing protocol can be called report Config. For example, the network device can configure one or more report Config for the terminal device. Each report Config includes the report index, report time, report period and report format. Report related information, where the reported index refers to the index that needs to be reported by the terminal device, such as RSRP and/or CRI. In addition, the reported configuration also includes an index of resource configuration (resource setting or resource Config), which is used to indicate which resource configuration the terminal device measures. For example, the reported configuration in this application includes the resource configuration to which the aforementioned L interference measurement resource sets belong And the index of the resource configuration to which the channel measurement resource set composed of M channel measurement resources belongs; or, if the above-mentioned L interference measurement resource sets and channel measurement resource sets belong to one resource configuration, the reported configuration includes the resource configuration index.

Exemplarily, the report Quantity in this embodiment can be configured into any form of report Quantity shown in FIG. 4, which is not repeated here.

In the method flow shown in Figures 4 and 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 respectively. The channel measurement resource set includes M resources, and the network device passes The indication information instructs the terminal device to report K resources in the channel measurement resource set. That is, in the method procedures 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 instruction of the network device. Further, considering that the network device may have determined which K resources in a channel measurement resource set are used for sending data through other means, but cannot determine the interference between the K resources and other resources, the network device can directly Configure the K resources and K interference measurement resource sets to determine the interference information of the K resources. The following describes in detail with reference to FIG. 6 how the network device configures K resources and L interference measurement resource sets for the terminal device.

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

S310: The network device sends second measurement configuration information to the terminal device.

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

It should be understood that in the embodiment shown in FIG. 6, before S310, the network device knows which K resources are used to send data. Specifically, the network device may be determined according to the measurement result of the historical terminal device.

In the embodiment shown in FIG. 6, the network device determines that the resources used to send data are the above-mentioned K resources through the historical measurement results, that is to say, when the channel measurement resource set is currently configured, the network device has learned that it is used to send data When configuring the channel measurement resource set, the network device can directly form a channel measurement resource set and configure the K interference measurement resource sets mentioned above to the terminal device when configuring the channel measurement resource set.

In this implementation manner, the network device knows the resources used for data transmission in advance, so the network device does not need to configure M resources when configuring the channel measurement resource set for the terminal device, which further reduces the resource overhead. For example, the network device allocates 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 based on the historical measurement result, the network device determines 2 resources for data transmission Under the premise of resources, only the two resources and two interference measurement resource sets need to be configured, thereby reducing the overhead of interference measurement resources.

It should be understood that this application only limits the second measurement configuration information to include K resources and K interference measurement resource sets, but it does not limit the second measurement configuration information to only include the above information. For example, it may also include report configuration information. The reported configuration information is used to configure the related information of the measurement result sent by the terminal device to the network device.

It should be understood that this application only limits that the second measurement configuration information sent by the network device needs to include the above K resources and K NZP CSI-RS resource sets, and there is no restriction on whether the second measurement configuration information includes other resource sets. . For example, similar to the measurement configuration information described in FIG. 4, the second measurement configuration information shown in FIG. 6 may also include a CSI-IM resource set. For the specific description of the CSI-IM resource set, refer to the description of the CSI-IM resource set in FIG. 4, which will not be repeated here.

Specifically, in order to implement the terminal device to measure the interference information of K resources separately, the K interference resource sets need to satisfy a certain fifth time relationship. For example, the fifth time relationship may be any of the following cases :

The last time slot in the time unit where the resource in the previous interference measurement resource set is located in the two arbitrarily adjacent interference measurement resource sets in time of the K interference measurement resource sets is larger than the last time slot in the next interference measurement resource set. The first time slot in the time slot where the resource is located is at least X time slots earlier;

The last symbol in the symbol where the resource in the previous interference measurement resource set is located in the two adjacent interference measurement resource sets adjacent in time in the K interference measurement resource sets is shorter than the resource in the next interference measurement resource set. The first symbol in the symbols is at least X symbols earlier;

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

In the K different symbol sets where the K interference measurement resource sets are located, at least X symbols are spaced between every two symbol sets.

Alternatively, the fifth time relationship is expressed in the form of a formula, which can be any of the following situations:

S _{IMR_after} -S _{IMR_before} >=Th _{slot_5}

Th _{slot_5} is the fifth slot threshold, a positive integer, and the unit is a slot.

F _{IMR_after} -F _{IMR_before} >= Th _{symbol_5}

Th _{symbol_5} is the fifth symbol threshold, which is a positive integer and the unit is a symbol.

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 has known K resources for sending data, so there is no need to limit the time relationship between the K resources and the aforementioned K interference resource sets, because the K resources The resource must be earlier in time than the above K interference resource sets.

Further, after performing the above S310, in order for 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 set, namely In step 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 described above.

Among them, the network device sends K first measurement signals to the terminal device according to the configuration of the above K resources; the network device sends to the terminal device respectively according to the configuration of the resources in each interference measurement resource set in the K interference measurement resource sets K second measurement signal sets, where the first measurement signal and the second measurement signal set are used to measure at least one resource in the interference measurement resource set that sends the second measurement signal set, and the information received by the receiving beam receiving the second measurement signal set Interference between resources corresponding to the first measurement signal.

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

Specifically, what the terminal device can measure the interference information of the resource may be that after the terminal device determines the K resources that need to be reported, it measures the K L1-SINRs corresponding to the K resources. Among them, the L1-SINR of the resource may also be referred to as the 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 the resources in the K interference measurement resource sets. The above 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 interference measurement resource sets have the same TCI state Have the same QCL assumptions. The QCL type can be Type D or Type A. The K resources are in one-to-one correspondence with the K interference measurement resource sets, and the terminal device uses the receiving beam for receiving the first measurement signal to receive the second measurement signal set sent by the interference measurement resource set corresponding to the resource. Therefore, the terminal device can 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 set. That is, the terminal device assumes that the resources in the K interference measurement resource sets are quasi-coordinated QCLed with the K resources to be reported.

The K resources mentioned above correspond to the K interference measurement resource sets in a one-to-one relationship, which are similar to those shown in FIG. 4 and will not be described here.

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

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

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

2) The terminal device reports the L1-SINR corresponding to the K resources according to the configuration order of the K resources;

3) When multiple L1-SINRs need to be reported for one, the multiple L1-SINRs are arranged in ascending order or descending order. The terminal device may also report the index of the resource in the interference measurement resource set used 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, measure at least L of the K resources based on the L interference measurement resource sets. The interference information of is similar to the interference information of at least L of the K resources measured on the basis of the L interference measurement resource sets in FIG. 5, which will not be illustrated here.

It should be understood that in the foregoing method embodiments, the size of the sequence numbers of the foregoing processes does not mean the order of execution, and the execution order of the processes should be determined by their functions and internal logic, and should not correspond to the implementation process of the embodiments of this application. Constitute any limitation.
