Description

Communication method and device

Technical Field

The present application relates to the field of communications technologies, and in particular, to a communication method and apparatus.

Background

Fifth generation mobile communication system (5)^thgeneration, 5G) employs analog beam based high frequency communication. The network device needs to employ a particular beam to transmit data for a particular user. This beam is called a service beam. Before data transmission, the network device needs to acquire Channel Quality Information (CQI) of a service beam to decide what modulation to useCoding techniques are used to transmit data. When the network device antenna has multiple channels, the network device may transmit data simultaneously for multiple users via multiple beams. As shown in the diagram of fig. 1, when receiving data through a serving beam, a user also receives signals of other beams, thereby causing interference to its data transmission. This interference is called intra-cell interference and the other beams are called interfering beams. The network device needs to obtain the intra-cell interference information to avoid strong interference caused by signals on a plurality of beams transmitted simultaneously, thereby ensuring efficient data transmission. The interference information in the cell is obtained by the channel measurement and reporting of the terminal equipment.

In the prior art, a method for measuring channel quality information under interference of a specific interference beam is to measure a channel CQI under interference of the specific interference beam by configuring a resource for channel measurement and a resource for interference measurement for a UE, so as to obtain interference information. For example, the base station configures one resource #1 for channel measurement and a plurality of resources #2, #3, #4 for interference measurement to the UE. Each resource is associated with a respective beam. For example, the relationship is: resource # 1-beam a, resource # 2-beam b, resource # 3-beam c, resource # 4-beam d. Then, with the above configuration, the base station can obtain the channel CQI of beam a while under the interference of beam b, beam c, and beam d. The method defaults to using all interference resources to calculate the channel CQI, but cannot calculate the channel CQI under the interference of each interference wave beam; and can only be used for measuring CQI information under interference, but can not obtain other interference measurement results.

Another way may be to implement separate measurement of the channel CQI under the interference of each interfering beam. The technique employs multiple sets of configurations to measure CQI under interference from various interfering beams. For example, the base station configures multiple sets of measurement configuration information for the UE, which are respectively: channel resource #1+ interference resource #2, channel resource #1+ interference resource 3, and channel resource #1+ interference resource 4. The UE performs the three sets of configurations respectively, and may measure CQI information under interference of each interference beam respectively. However, this method is expensive in measurement, and a set of measurement configuration information needs to be configured for each interference beam. In addition, it can only be used to measure CQI information under interference, but cannot obtain other interference measurement results.

Therefore, the configuration of the measurement resources for performing interference measurement is relatively fixed, the obtained interference information is relatively single, and the network device cannot flexibly perform interference avoidance scheduling according to the interference measurement result, so that the data transmission performance is improved.

Detailed Description

Fig. 2 presents a schematic view of a communication system to which the present application relates. The communication system may include at least one network device 100 (only 1 shown) and one or more terminal devices 200 connected to the network device 100.

The embodiments of the present application do not limit the specific technologies and the specific device forms used by the network devices.

The terminal device 200 is a device with a wireless transceiving function, and can be deployed on land, including indoors or outdoors, hand-held, worn or vehicle-mounted; can also be deployed on the water surface, such as a ship and the like; and may also be deployed in the air, such as airplanes, balloons, satellites, and the like.

The embodiments of the present application do not limit the application scenarios. A terminal device may also sometimes be referred to as a User Equipment (UE), an access terminal device, a UE unit, a mobile station, a remote terminal device, a mobile device, a terminal (terminal), a wireless communication device, a UE agent, a UE device, or the like.

It should be noted that the terms "system" and "network" in the embodiments of the present invention may be used interchangeably. The "plurality" means two or more, and in view of this, the "plurality" may also be understood as "at least two" in the embodiments of the present invention. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" generally indicates that the preceding and following related objects are in an "or" relationship, unless otherwise specified.

The following explains several terms that may be referred to by embodiments of the present application:

beam (beam): a beam means that the energy of the radio signal is concentrated in a small area, thereby forming an effect similar to a light beam. High frequencies transmit signals through the beam, which may increase the transmission distance of the signals. The beams are generated by beam forming techniques, which include digital beam forming techniques, analog beam forming techniques, and hybrid digital/analog beam forming techniques. Beams generated by digital beamforming techniques are referred to as digital beams, while beams generated by analog beamforming techniques are referred to as analog beams.

Serving beam (serving beam): the network device schedules beams for data transmission to the terminal device.

Interference beam (interference beam): other beams, which are scheduled with the serving beam, may interfere with the data on the serving beam.

Channel measurement (CSI acquisition): the quality of the service beam is measured, including channel state information-reference resource index (CRI), Rank Indication (RI), Precoding Matrix Indication (PMI), LI, i1, CQI, and the like.

Interference measurement (Interference measure): and measuring information of the interference beam, wherein the information comprises the identification of the strong interference beam/resource, the identification of the weak interference beam/resource, the CQI of the service beam under the interference of the interference beam and the like.

In the present application, a resource has a correspondence with a beam.

Interference measurements are required prior to data transmission. One existing method is to configure a UE with a resource for channel measurement and a resource for interference measurement to measure a channel CQI under interference of a specific interference beam, so as to obtain interference information. For example, the base station configures one resource #1 for channel measurement and a plurality of resources #2, #3, #4 for interference measurement to the UE. Each resource is associated with a respective beam. For example, the relationship is: resource # 1-beam a, resource # 2-beam b, resource # 3-beam c, resource # 4-beam d. Then, with the above configuration, the base station can obtain the channel CQI of beam a while under the interference of beam b, beam c, and beam d. A first drawback of this method is that it is not possible to calculate the channel CQI under interference of each interference beam separately, by default, by using all interference resources to calculate the channel CQI. The second disadvantage is that the method can only be used for measuring CQI information under interference, but cannot obtain other interference information such as interference beam ID.

Another existing method is to use multiple sets of configurations to measure the CQI under interference from each interfering beam. For example, the base station configures multiple sets of measurement configuration information for the UE, which are respectively: channel resource #1+ interference resource #2, channel resource #1+ interference resource 3, and channel resource #1+ interference resource 4. The UE performs the three sets of configurations respectively, and may measure CQI information under interference of each interference beam respectively. The first disadvantage of this method is that the measurement overhead is large, and a set of measurement configuration information is configured for each interference beam. In addition, it can only be used for measuring CQI information under interference, but cannot obtain other interference information such as interference beam ID.

Fig. 3 is a flowchart illustrating a communication method according to an embodiment of the present application, which can be applied to the communication system. Wherein:

s101, the network equipment sends a reference signal to the terminal equipment. The terminal device receives reference signals from the network device on a plurality of measurement resources.

The network equipment transmits reference signals through a plurality of beams, and the terminal equipment receives the reference signals transmitted through the service beams and carries out channel measurement. Meanwhile, the terminal device may also receive reference signals transmitted by other beams, which are interference beams. Here, the beam corresponds to the configured measurement resource.

Further, before S101, the method further includes the following steps: and the network equipment sends the measurement resource configuration information and/or the measurement report configuration information to the terminal equipment. The terminal device receives the measurement resource configuration information and/or measurement reporting configuration (reportConfig) information. Specifically, the network device may perform configuration of measurement resources and measurement reports through a high-level signaling.

Wherein the configured measurement resources include one or more of: the first resource for channel measurement, one or more second resources for intra-cell interference measurement, and a third resource for inter-cell interference measurement.

The second resource may specifically be an interference measurement based on a non-zero power channel state information-reference signal (NZP CSI-RS); the third resource may specifically be an interference measurement based on channel state information-interference management (CSI-IM).

For example, as shown in table 1 below, the measurement resource configuration information includes: resource setting #1, resource setting #2, and resource setting # 3. Resource setting #1 is used for channel measurement, resource setting #2 is used for CSI-IM based interference measurement, and resource setting #3 is used for NZP CSI-RS based interference measurement. That is, resource #1 is configured for channel measurement, resource #2 is configured for inter-cell interference measurement, and resources #3 to #6 are configured for intra-cell interference measurement.

Table 1 configuration of measurement resources

Resource setting #1	Resource #1
		Resource setting #2	Resource #2
Resource setting #3	Resource #3, resource #4, resource #5, resource #6

Wherein the measurement reporting configuration information includes one or more of the following information: indication of channel quality information calculation principle, measurement reporting amount (report quality), type of interference resource, number of reported interference resources, and interference degree information of the strong interference resource and/or the weak interference resource.

The network device can modify the existing reporting quantity and configure the terminal device to report the reporting quantity. Or, instead of modifying the existing reporting amount, a field may be specifically added to the measurement reporting configuration information to indicate whether the terminal device reports the interference measurement resource CRI, or to indicate how the terminal device calculates the CQI.

In this embodiment, the channel quality information is calculated without considering the energy on the configured second resource when calculating the CQI. The calculation principle is used to constrain the behavior of the terminal device.

In one implementation, the protocol may add a field in the measurement report configuration information to indicate the calculation principle of the channel quality information. If the channel quality information calculation principle field is configured to X, then the energy of all second resources is not accounted for in the calculation of the channel quality information and the terminal device needs to determine the identity of the strong/weak interference resource from the configured one or more second resources. Wherein, the value of X can be set according to the requirement.

In another implementation, a special field may not be set to indicate the principle of calculating the channel quality information, but if the measurement report is configured as one or more of the following reports, the energy of all the second resources is not included in the calculation of the channel quality information, and the terminal device needs to determine the identity of the strong/weak interference resource from the configured one or more second resources. I.e. the calculation of channel quality information does not account for energy on all second resources when measurement reports are configured as one or more of said measurement reports.

Wherein the measurement reports include one or more of: CRI, RI, PMI, LI, i1, CQI, or identification of interfering resources.

In particular, the measurement reports may be any combination of these reports. For example, it may be any combination of the following:

channel measurement resource CRI-RI-i 1-interference measurement resource CRI;

channel measurement resource CRI-RI-i 1-CQI-interference measurement resource CRI;

channel measurement resource CRI-RI-CQI-interference measurement resource CRI;

channel measurement resource CRI-RI-PMI-CQI-interference measurement resource CRI;

channel measurement resource CRI-i 1-CQI-interference measurement resource CRI;

channel measurement resource CRI-RI-LI-PMI-CQI-interference measurement resource CRI.

For the above calculation principle, in other words, if the reporting amount in the measurement reporting configuration information configured by the upper layer is configured as any one of the following combinations: CRI-RI-PMI-CQI-interference measurement resource CRI, CRI-RI-i 1-interference measurement resource CRI, CRI-RI-i 1-CQI-interference measurement resource CRI, CRI-RI-CQI-interference measurement resource CRI, or CRI-RI-LI-PMI-CQI-interference measurement resource CRI, then the second resource is not counted as interference in CQI when the terminal device calculates CQI (or only the first resource and the third resource are considered when the terminal device calculates CQI).

Or, if the reporting amount in the measurement reporting configuration information configured by the upper layer includes the interference measurement resource CRI, the second resource is not included as interference in the CQI when the terminal device calculates the CQI (or only the first resource and the third resource are considered when the terminal device calculates the CQI).

The types of the interference resources include strong interference resources and weak interference resources. The network device configures the terminal device to report the type of the interference resource when the terminal device performs measurement reporting.

For the determination of the type of the interference resource, if the report amount in the measurement report configuration information configured by the upper layer is configured as any one of the following combinations: CRI-RI-PMI-CQI-interference measurement resource CRI, CRI-RI-i 1-interference measurement resource CRI, CRI-RI-i 1-CQI-interference measurement resource CRI, CRI-RI-CQI-interference measurement resource CRI, or CRI-RI-LI-PMI-CQI-interference measurement resource CRI, the terminal device needs to determine the CRI of the strong interference resource or the weak interference resource through the configured first resource, second resource, and/or third resource. I.e. when measurement reports are configured as one or more of said measurement reports, determining an identification of strong interfering resources and/or an identification of weak interfering resources by said one or more second resources.

Or, if the reporting amount in the measurement reporting configuration information configured by the upper layer includes the interference measurement resource CRI, the terminal device needs to determine the CRI of the strong interference resource or the weak interference resource through the configured first resource, second resource and/or third resource.

The network device may also configure the number of interference resources reported by the terminal device, that is, the number of strong interference resources and/or the number of weak interference resources. The identity of the interfering resources in the measurement report may be one or more.

In addition, the network device may also configure the interference degree information of the strong interference resource and/or the weak interference resource reported by the terminal device. The interference level information may be the above RSRP or RSRQ.

S102, the terminal device measures the energy of the reference signal on each resource.

The terminal equipment receives the reference signals on a plurality of measurement resources, and obtains the energy transmitted by the network equipment through the wave beams. The terminal device measures the energy of the reference signal on each resource. The measured energy may be represented in various forms, such as Reference Signal Receiving Power (RSRP) or Reference Signal Receiving Quality (RSRQ).

S103, the terminal equipment determines channel quality information according to the energy measured on the first resource and the energy measured on the third resource.

In this embodiment, interference energy on the interference measurement resource based on the NZP CSI-RS is not considered. Taking the above configured resources as an example, the CQI obtained according to formula 1 is:

wherein, P_channelRefers to the measured energy, P, on the first resource (e.g., resource #1 above)_CSI-IMRefers to the measured energy on the third resource (e.g., resource #2 above).

In another embodiment, if the report amount in the measurement report configuration information configured by the upper layer is configured as any one of the following combinations: CRI-RI-PMI-CQI-interference measurement resource CRI, CRI-RI-i 1-interference measurement resource CRI, CRI-RI-i 1-CQI-interference measurement resource CRI, CRI-RI-CQI-interference measurement resource CRI, or CRI-RI-LI-PMI-CQI-interference measurement resource CRI, then when calculating CQI, the energy mean of all configured second resources is counted as interference energy into CQI. Or if the reporting quantity in the measurement reporting configuration information configured by the upper layer includes the interference measurement resource CRI, when the CQI is calculated, the energy average value of all the configured second resources is taken as the interference energy to be added into the CQI. I.e. the energy of all second resources is averaged and calculated into the CQI.

S104, the terminal device determines a strong interference resource and/or a weak interference resource in the one or more second resources according to the energy measured on the first resource and the energy measured on the one or more second resources.

The method comprises the step of determining the type and the identification of an interference wave beam from an NZP CSI-RS interference measurement resource. Specifically, the CQI or RSRQ may be used. For example, the CQI or RSRQ is calculated using the energy on each interference resource, respectively, and then it is determined which interference measurement resource corresponds to a strong/weak interference beam according to the value of the CQI or RSRQ. The application does not limit the specific comparison index and method.

As an implementation, calculating a ratio of the energy measured on the first resource to the energy measured on each second resource to obtain a plurality of energy ratios; and comparing the plurality of energy ratios, taking the second resource corresponding to the maximum energy ratio as a strong interference resource, and taking other second resources except the strong interference resource as weak interference resources.

For example, the interference degree of each beam corresponding to the NZP CSI-RS interference measurement resource to the service beam corresponding to the channel measurement resource can be estimated by formula 2:

suppose RSRQ_3-1>RSRQ_4-1It means that the interference caused by the beam corresponding to resource #3 is smaller than the interference caused by the beam corresponding to resource # 3.

As another implementation manner, the second resource corresponding to the energy ratio value with the energy ratio value greater than or equal to the set value is used as a strong interference resource, and other second resources except the strong interference resource are used as weak interference resources.

As another implementation, the energy ratio R1 of the first resource and the third resource is calculated first, i.e. the first resource/the third resource; reintroducing the energy of the second resource to calculate R2 ═ the first resource/(the second resource + the third resource); and judging whether the second resource is a strong interference resource or a weak interference resource according to the values of R2 and R1. Strong interference determination conditions: R1-R2> X, X is a threshold value in dB; if the interference judging condition is: R1-R2< Y, which is the threshold value, in dB.

Of course, the method is not limited to the above method of determining the strong/weak interference resources.

S105, the terminal equipment reports one or more of the following information to the network equipment: the channel quality information, an identification of the strong interference resource, and/or an identification of the weak interference resource. The network equipment receives one or more kinds of information reported by the terminal equipment.

In this embodiment, the terminal device feeds back the CQI and the identifier of the interference resource through a specific reporting format. The current protocol does not support the reporting of the identifier of the interference resource, so that an identifier field of the interference resource needs to be newly added in the existing reporting format.

When a terminal device uses a Physical Uplink Control Channel (PUCCH)/Physical Uplink Shared Channel (PUSCH) to report CSI reports and an identifier of an interference resource, a protocol needs to support a reporting format corresponding to the various reporting amounts, taking CRI-RI-PMI-CQI-CRI as an example, and the reporting format is shown in table 2 below:

table 2 report format

Wherein the content of the first and second substances,

refers to the number of resources for measuring interference based on NZP CSI-RS,

refers to the number of resources based on channel measurements. The bit lengths are exemplary.

Further, the reporting format of the terminal device may also support reporting of CRI of multiple interference resources, for example: the method comprises the steps that a terminal device reports a measurement result through a message format of PDCCH or PDSCH, wherein the message format comprises one or more interference measurement resources CRI, the channel measurement resources CRI-PMI-CQI-first interference measurement resources CRI-second interference measurement resources CRI ….

Further, reporting of interference degrees such as multiple RSRQs can be supported, for example, reporting of a measurement result by a terminal device through a message format of PDCCH or PDSCH, where the message format includes one or more interference measurement resources CRI and RSRPs corresponding to the respective interference measurement resources CRI, is performed by a terminal device including channel measurement resources CRI-RI-PMI-CQI-first interference measurement resource CRI-RSRQ corresponding to the first interference measurement resource CRI-second interference measurement resource CRI-and RSRQ … corresponding to the second interference measurement resource CRI. After the network equipment obtains the reported interference degree information, the scheduling can be more accurately carried out, and the scheduling to the strong interference wave beam is avoided.

The present application does not exclude the terminal device from reporting in other uplink transmission manners, for example, using encapsulated data units such as MAC-CE.

The interference measurement resource and the interference wave beam have a corresponding relation, and the network equipment can correspond to the identifier of the specific wave beam only by determining the identifier of the interference resource and feeding the identifier back to the network equipment by the terminal equipment.

As can be seen from the above description, the terminal device reports channel quality information (without counting intra-cell interference) and an identifier of an interference resource (including an identifier of a strong interference and/or a weak interference resource) through measurement configuration, and the network device performs interference avoidance scheduling according to the channel quality information reported by the terminal device and the identifier of the interference resource, so as to avoid strong interference between beams simultaneously scheduled. And when scheduling, excluding strong interference pairing or prioritizing a plurality of interference pairing. Thus, the interference between the simultaneously scheduled multiple beams is weak, and the actual channel quality information is closer to the reported channel quality information (without accounting for intra-cell interference). The channel quality information (not accounting for intra-cell interference) is therefore matched to the actual channel quality, improving the accuracy of the network device scheduling.

According to the current standard, after the terminal device is configured with the interference beam resource, the energy of all the second resources is taken into the CQI by default, while the calculation of the CQI of the embodiment does not take the energy of the second resources into account, and the identity of the strong interference resource and/or the weak interference resource is determined. It is therefore possible to add such measurement behavior related descriptions in the protocol.

According to the communication method and the communication device provided by the embodiment of the application, the network equipment can be supported to carry out interference avoidance scheduling by configuring the channel quality information reported by the terminal equipment and the identification of the interference resource, and strong interference between beams scheduled at the same time is avoided.

In the prior art, a network device configures a resource (e.g., resource #1) for channel measurement, one or more resources (e.g., resource #3 to resource #6, specifically NZP CSI-RS resources) for intra-cell interference measurement, and a resource (e.g., resource #2, specifically NZP CSI-IM resources) for inter-cell interference measurement for a terminal device. The beams associated with these several resources in the cell may all interfere with the serving beam corresponding to resource # 1. The beam associated with the inter-cell resource (resource #2) may cause white noise interference to the service beam corresponding to resource # 1. Therefore, the terminal device calculates the channel quality information of the service beam under the influence of the interference beams in these cells according to equation 3 as shown below:

wherein, P_channelIs the signal energy on the resource used for channel measurement (resource #1) which characterizes the signal strength of the serving beam. P_NZPIMRIs the signal energy on the resource for intra-cell interference measurement, if multiple resources for interference measurement are configured, the signal energy on all interference measurement resources need to be accumulated (resource # 3-resource # 6). P_CSI-IMIs based on other interference energy of CSI-IM (resource #2), including, for example, white noise and interference of other cells.

The existing scheme calculates the CQI by means of the superimposed interference. That is, if multiple interference resources are configured, the terminal device may calculate all the energy on all the interference resources into the CQI, and calculate one CQI. Therefore, if the network device wants to measure CQIs respectively affected by multiple interference beams, the terminal device needs to be configured to perform multiple measurements, which increases the measurement overhead.

The application also provides another communication method and device, and the network equipment can measure and report the channel quality information under each interference hypothesis through one-time configuration, so that the resource overhead is low; when scheduling transmission is carried out, the scheduled wave beams can be determined according to the obtained channel quality information under each interference hypothesis, so that the scheduling efficiency and flexibility are improved.

Fig. 4 is a flowchart of another communication method provided in the embodiment of the present application, which can be applied to the communication system shown in fig. 2. Wherein:

s201, the network equipment sends a reference signal to the terminal equipment. The terminal device receives reference signals from the network device on a plurality of measurement resources.

Wherein the measurement resources include one or more of: the first resource for channel measurement, one or more second resources for intra-cell interference measurement, and a third resource for inter-cell interference measurement.

Further, before S201, the method further includes the following steps: and sending measurement resource configuration information and/or measurement report configuration information to the terminal equipment. And the terminal equipment receives the measurement resource configuration information and/or the measurement reporting configuration information.

The network device configures a resource (e.g., resource #1) for channel measurement, one or more resources (e.g., resource #3 to resource #6, specifically NZP CSI-RS resources) for intra-cell interference measurement, and a resource (e.g., resource #2, specifically NZP CSI-IM resources) for inter-cell interference measurement for the terminal device. The beams associated with these several resources in the cell may all interfere with the serving beam corresponding to resource # 1. The beam associated with the inter-cell resource (resource #2) may cause white noise interference to the service beam corresponding to resource # 1.

Specifically, when the network device is configured, as shown in table 1, the measurement resource configuration information includes a configuration resource #1 for measurement of a channel, a configuration resource #2 for interference measurement based on CSI-IM, and configuration resources #3 to #6 for interference measurement based on NZP CSI-RS.

In addition, the measurement reporting configuration information includes one or more of the following information: the channel quality information calculates an indication of a principle, or a measurement report.

Wherein the measurement reports include one or more of: channel state information-reference resource index CRI, rank indication RI, precoding matrix indication PMI, LI, i1, channel quality information CQI or identification of interference resources.

In this embodiment, the CQI calculation principle is to calculate the energy of the interference resources in each cell into the CQI and calculate a plurality of CQIs when calculating the CQI.

S202, the terminal device measures the energy of the reference signal on each resource.

The terminal equipment receives the reference signals on a plurality of measurement resources, and obtains the energy transmitted by the network equipment through the wave beams. The terminal device measures the energy of the reference signal on each resource. The measured energy may be represented in various forms, for example, it may be RSRQ.

S203, the terminal device determines the channel quality information corresponding to each second resource according to the energy measured on the first resource, the energy measured on each second resource and the energy measured on the third resource.

And the terminal equipment respectively calculates the energy on each second resource into the CQI to obtain the CQI under each interference hypothesis.

Taking the above specific configuration example, the terminal device needs to calculate channel quality information corresponding to 4 resources for interference measurement: { CQI_3-1,CQI_4-1,CQI_5-1,CQI_6-1The calculation formula is shown in the following formula 4:

wherein, i may be 3, 4, 5, 6.

According to the current standard, after the terminal device is configured with resources for interference measurement, it will default to calculating the channel quality information in the prior art manner, instead of calculating the channel quality information separately with each interference resource. There is therefore a need to add such measurement behavior related descriptions to the protocol.

And S204, the terminal equipment reports the identifier of each second resource and the channel quality information corresponding to each second resource to the network equipment. And the network equipment receives the reported identifier of each second resource and the channel quality information corresponding to each second resource.

And the terminal equipment feeds back the CQI under each interference hypothesis and the identification of the second resource corresponding to each CQI. In the prior art, one reporting only includes one CQI, so this embodiment needs to expand the CQI field of the reporting format to multiple CQI fields. In addition, each CQI field corresponds to an interference resource ID field. As shown in table 3 below.

And the terminal equipment feeds back the CQI corresponding to each interference resource through a specific reporting format. The current standard does not support reporting multiple CQIs at one time, so the current reporting format needs to be modified.

The measurement report quantity configured by the network equipment comprises one or more of the following report quantities: CRI, RI, PMI, LI, i1, CQI, or identification of interfering resources. Any combination of these reported amounts is possible. For example, the following combinations are possible:

channel measurement resource CRI-RI-i 1-interference measurement resource CRI

Channel measurement resource CRI-RI-CQI-interference measurement resource CRI

Channel measurement resource CRI-RI-PMI-CQI-interference measurement resource CRI

Channel measurement resource CRI-i 1-CQI-interference measurement resource CRI

Channel measurement resource CRI-RI-LI-PMI-CQI-interference measurement resource CRI

Further, reporting of multiple CQI and interference measurement resources, CRI, may be supported, for example: channel measurement resource CRI-RI-PMI-first CQI-first interference measurement resource CRI-second CQI-second interference measurement resource CRI …

When the terminal device uses PUCCH/PUSCH to report CSI and/or beam, the protocol needs to support a reporting format corresponding to the various reported amounts, taking channel measurement resource CRI-RI-PMI-CQI-interference measurement resource CRI as an example, the reporting format is shown in table 3:

table 3 report format of report volume

Wherein the content of the first and second substances,

refers to the number of resources based on channel measurements. Bit thereinThe lengths are exemplary.

The present embodiment enables the terminal device to measure the channel quality information under the interference of the specific beam by configuring the resource for interference measurement. In the prior art, when a network device configures a plurality of interference measurement resources for a terminal device, the terminal device calculates energy on all interference resources into a CQI, and reports one CQI. In this embodiment, energy on each interference resource is calculated into CQI, and multiple CQIs are reported.

In this embodiment, the terminal device can measure and report the CQIs corresponding to the multiple interference beams through one configuration, whereas in the prior art, the terminal device needs to be configured multiple times and report the CQIs multiple times, which results in high resource overhead.

According to the communication method provided by the embodiment of the application, the network equipment can measure and report the channel quality information under each interference hypothesis through one-time configuration, so that the resource overhead is low; when scheduling transmission is carried out, the scheduled wave beams can be determined according to the obtained channel quality information under each interference hypothesis, so that the scheduling efficiency and flexibility are improved.

As can be seen from the above embodiments, when the terminal device is configured with one resource for channel measurement and one or more resources for interference measurement, the terminal device has multiple CQI calculation criteria: the calculation of the channel quality information does not account for the energy on all second resources ("criterion one"), the channel quality information for all interference superpositions ("criterion two") is calculated, and the corresponding channel quality information under the respective interference hypotheses ("criterion three") is calculated.

Which calculation criterion the terminal device specifically adopts may be indicated by the network device.

One way to implement this is that the network device indicates, in the measurement configuration, which CQI calculation criterion the terminal device employs, by means of a special field. As shown in table 4 below:

table 4 indicating CQI calculation criteria by special fields

Field of calculation criteria	Means of	Behavior of terminal device
			0	Criterion one	Computing CQI and Strong/Weak interference Beam IDs
1	Criterion three	Respectively calculating CQI corresponding to each interference wave beam
			2	Criterion two	Computing CQI for all interference beam superposition

By adopting the indication method, the indication is clear.

Another way of implementing this is by not having a dedicated field, but by having an implicit indication of the field already present.

One implicit indication method is to indicate by the number of configured interference measurement resources. As shown in table 5 below:

TABLE 5 implicit indication method based on interference measurement resources

Another implicit indication method is by reporting amount. When the report amount includes the interference measurement resource CRI (ID of the interference resource), the terminal device adopts the calculation criterion one. Otherwise, adopting the calculation method of the criterion two.

By adopting the implicit indication method, the overhead of indication information can be saved.

The present application further provides another communication method and apparatus, which can simultaneously determine a resource (i.e., a service beam) for channel measurement and measure corresponding channel quality information, thereby simplifying a procedure and improving scheduling efficiency.

Fig. 5 is a flowchart illustrating another communication method according to an embodiment of the present application, which can be applied to the communication system shown in fig. 2. Wherein:

s301, the network equipment sends a reference signal to the terminal equipment. The terminal device receives reference signals from the network device on a plurality of measurement resources.

The network equipment transmits the reference signal through a plurality of beams, and the terminal equipment receives the reference signal through the beams corresponding to a plurality of measurement resources.

Further, before S301, the method further includes: and sending measurement resource configuration information and/or measurement report configuration information to the terminal equipment. And the terminal equipment receives the measurement resource configuration information and/or the measurement reporting configuration information.

Wherein the measurement resources include one or more of: a plurality of first resources for channel measurement and/or intra-cell interference measurement, and a second resource for inter-cell interference measurement.

In this embodiment, the network device does not explicitly indicate the resources for channel measurement and the resources for interference measurement when making the measurement resource configuration.

For example, the measurement resource configuration of the network device is shown in table 6 below:

TABLE 6 resource setting

Resource setting #1	Resource #1, resource #2, resource #3, resource #4
		Resource setting #2	Resource #5

The resource configuration comprises the following steps: and configuring resources # 1-4 for channel measurement and interference measurement based on NZP CSI-RS, and configuring resource #5 for interference measurement based on CSI-IM.

In addition, the measurement reporting configuration information includes one or more of the following information: an indication of the channel quality information calculation principle.

In this embodiment, the CQI calculation principle is to calculate the CQI by superimposing all the interferences together, or calculate the CQI corresponding to each interference hypothesis.

S302, the terminal device measures the energy of the reference signal on each resource.

S303, the terminal device determines channel quality information corresponding to each first resource by using each first resource as a resource for channel measurement.

And the terminal equipment takes each first resource as a resource corresponding to the service beam and takes other first resources as intra-cell interference resources, calculates CQI and obtains a plurality of CQI. In the above resource configuration example, the calculation formula is shown in formula (5):

calculating CQI according to formula 4_#1. Computing resources in the same way#2 to #4 are CQIs for serving the resources corresponding to the beams. Four CQIs are thus obtained: { CQI_#1,CQI_#2,CQI_#3,CQI_#4}。

S304, the terminal device selects the first resource corresponding to the maximum value in the plurality of channel qualities as the resource for channel measurement.

And selecting a first resource corresponding to the maximum CQI from the plurality of CQIs as a resource for channel measurement, wherein a beam corresponding to the first resource is a service beam.

E.g. CQI_#1Which is the largest of the four CQIs, the terminal device selects the beam corresponding to resource #1 as the serving beam and the other beams as the interfering beams.

S305, the terminal device reports the identifier and the channel quality information of the first resource selected as the channel measurement to the network device. The network device receives an identification and channel quality information selected as a first resource for channel measurement.

The terminal device selects the beam corresponding to resource #1 as a service beam and the other beams as interference beams. The terminal device reports the ID of resource #1 and the corresponding CQI_#1。

According to the communication method provided by the embodiment of the application, the resource (namely, the service beam) for channel measurement and the corresponding channel quality information can be determined at the same time, the process is simplified, and the scheduling efficiency is improved.

Please refer to fig. 14, which is a flowchart illustrating another communication method according to an embodiment of the present application. Wherein:

s401, the network equipment sends measurement configuration information. The terminal device receives the measurement configuration information.

The acquisition of the interference measurement results is obtained by measurement. The network device configures corresponding measurement configuration information to the terminal device, informs the terminal device what pilot frequency resource to measure, and how to report the measurement result after the measurement. And the terminal equipment measures and reports the interference measurement result according to the measurement configuration information configured by the network equipment. The measurement configuration information includes measurement resource configuration information and measurement reporting configuration information. Other information may also be included.

The measurement resource configuration information divides the measurement resources into three levels: resource setting, resource set, and resource. The network device may configure one or more resource setting for the terminal device, where each resource setting may include one or more resource sets, and each resource set may include one or more resources. Each resource is a measurement pilot resource. Each resource has an ID, which is called CRI (CSI-RS Index) when the resource is of the type NZP CSI-RS, and ssb Index when the resource is of the type SS block.

Wherein the measurement configuration resources include measurement resources for interference measurement and measurement resources for channel measurement. The measurement resource used for interference measurement is one or more measurement resources in the same measurement resource set configured by the measurement configuration information, or one or more measurement resources in different measurement resource sets configured by the measurement configuration information. The terminal device may explicitly indicate the resources for measurement according to a field in the measurement configuration information, or may implicitly indicate the resources for measurement in another manner.

The measurement reporting configuration information includes resource setting, reporting amount, RSRQ calculation indication, CRI type, CRI number, channel measurement indication, reporting frequency domain configuration, reporting time domain configuration, reporting period, and carrier frequency of measurement associated with the measurement reporting configuration. Wherein the RSRQ calculation indication is used for instructing the terminal equipment to calculate the RSRQ by adopting the indicated RSRQ calculation method. The CRI type is used for indicating the CRI type to be reported by the terminal equipment, and comprises one or more of the following types: a channel measurement resource CRI and an interference measurement resource CRI. The CRI number is used for indicating the CRI number of the interference measurement resource to be reported by the terminal equipment. The channel measurement indication is used for indicating the CQI calculation method adopted by the terminal equipment.

Specifically, each measurement reporting configuration is associated with one or more resource setting for indicating what resource is used to measure the required reporting amount. For example, the aperiodic measurement reporting configuration may associate three resource setting, the first is NZP CSI-RS resource setting for channel measurement, the second is CSI-IM resource setting for interference measurement, and the third is NZP CSI-RS resource setting for interference measurement. The present application may refer to two terms-a channel measurement resource identification and an interference measurement resource identification. The channel measurement resource identifier refers to a CSI-RS resource identifier (CRI) or an SSB resource identifier (SSB index) for channel measurement; similarly, the interference measurement resource identifier may be a resource CRI or SSB index for interference measurement. In addition, the "measurement resource set" or "resource set" referred to in the present application may specifically refer to resource setting or resource set or other resource combination manner.

S402, the network equipment sends a reference signal based on the measurement configuration information. And the terminal equipment receives the reference signal.

And the network equipment configures the measurement resource for the terminal equipment, and then transmits the reference signal based on the measurement resource. In this embodiment, the resource may correspond to a beam. The network device transmits a reference signal on one or more measurement resources, and the terminal device receives the reference signal through the one or more measurement resources.

And S403, the terminal equipment carries out interference measurement on the reference signal based on the measurement configuration information.

Specifically, the terminal device performs interference measurement on the reference signal according to the report quantity required by the measurement report configuration, and obtains a measurement result on the indicated resource.

For example, the terminal device calculates RSRQ of reference signals received on one or more measurement resources according to an RSRQ calculation indication included in the measurement configuration information. The RSRQ calculation indication may include a plurality of RSRQ calculation methods. When measuring RSRQ, a resource identity for calculating RSRQ may also be determined.

For another example, the terminal device calculates CQI of the reference signal received on the one or more measurement resources according to the channel measurement indication included in the measurement configuration information. When measuring CQI, the resource identity used for calculating CQI may also be determined.

And S403, the terminal equipment reports the interference measurement result.

And the terminal equipment reports the interference measurement result obtained by measurement. The interference measurements include one or more of: RSRP, RSRQ, RSSI, CQI, SINR, PMI, LI, il, channel measurement resource identification, interference measurement resource identification. And the network equipment receives the interference measurement result reported by the terminal equipment.

In addition, when reporting the interference measurement result, for example, reporting RSRQ or CQI, the terminal device may adopt a differential reporting mode to save the reporting overhead.

According to the communication method provided by the embodiment of the application, the terminal equipment carries out interference measurement and reporting according to actual measurement configuration, measurement resources and interference measurement results for the interference measurement can be flexibly configured, and the network equipment can flexibly carry out interference avoidance scheduling according to the interference measurement results, so that the data transmission performance is improved.

The following describes the interference measurement and reporting process in detail by taking RSRQ, interference measurement resource identifier, and CQI measurement and reporting as examples. For the measurement and reporting of other interference measurement results, reference may be made to the embodiments of the present application.

Please refer to fig. 15, which is a flowchart illustrating another communication method according to an embodiment of the present application.

In this embodiment, the terminal device may measure RSRQ based on one or more resources in the same resource set or one or more resources in different resource sets, and according to the RSRQ calculation indication, when calculating the RSRQ of one resource, respectively calculate RSRQ by taking all signals on all other resources in the resource set where the resource is located as interference, or respectively calculate RSRQ by taking the signals on the other resources as interference, or calculate RSRQ without taking the signals on the other resources as interference. And the terminal equipment reports the calculated RSRQ and/or the corresponding interference measurement resource identifier. The network equipment can perform interference avoidance scheduling according to the received RSRQ and/or the corresponding interference measurement resource identifier, and the data transmission performance is improved.

Specifically, the method comprises the following steps:

s501, the network equipment sends measurement configuration information. The measurement configuration information includes measurement resource configuration information and measurement reporting configuration information. The terminal device receives the measurement configuration information.

In the measurement resource configuration information, the measurement resources are configured into a three-level structure: resource setting-resource set-resource. The network device may configure one or more resource setting for the terminal device, where each resource setting includes one or more resource sets, and each resource Set may include one or more resources. Each resource may also contain one or more ports (ports).

The measurement report configuration information includes information related to measurement report, including one or more of the following: one or more resource setting and/or resource set and/or resource associated with the measurement reporting configuration, a report quantity (report quality), an RSRQ calculation indication, a reporting frequency domain configuration, a reporting time domain configuration, a reporting period, a measured carrier frequency, and the like. The reported quantity may include RSRQ and/or interference measurement resource identifier (may be CRI or ssbinder), and may further include one or more of the following information: channel measurement resource identification (which may be CRI or SSB index), RSRP, RSSI, SINR, CQI, PMI, LI, il, etc.

S502, the network equipment sends a reference signal based on the measurement resource configuration information. The terminal device receives the reference signal.

S503, the terminal equipment determines the report amount according to the measurement configuration information. The reported quantity comprises: RSRQ and/or interference measurement resource identity, and/or one or more of the following: channel measurement resource identification, RSRP, RSSI, SINR, CQI, PMI, LI, il, etc.

Specifically, the reporting amount may be decided by measuring the reporting amount in the reporting configuration information or other implicit manners. For example, as shown in table 7, the network device may configure the following reporting amounts or combinations of the reporting amounts through a high-level signaling to instruct the terminal device to report the corresponding reporting amounts:

TABLE 7

And S504, the terminal equipment measures the RSRQ according to the RSRQ calculation instruction.

When the report quantity configured by the network device includes RSRQ report, the terminal device should use the measurement resource set associated with the measurement report information to measure RSRQ. The resources used to measure RSRQ may be one or more resources within the same set of resources or one or more resources within different sets of resources. The resource set types here include: a set of channel measurement resources, a set of CSI-IM interference measurement resources, and a set of NZP-CSI-RS interference measurement resources.

One possible scenario is: the terminal device measures RSRQ, associates or configures a resource set (which may be a resource setting or resource set or resource composed of CSI-RS resource and/or SSB resource, but may be other resource sets), measures RSRQ according to measurement configuration information, and reports the measurement result. At this time, the terminal device may calculate RSRQ of the configured measurement resources within the set according to the configured RSRQ calculation indication. The RSRQ calculation indication is for instructing the terminal device to calculate RSRQ using the indicated RSRQ calculation method.

The RSRQ calculation method comprises one or more of the following methods:

The RSRQ is a ratio of a reference signal power to be measured to an interference power in a measurement range, and a specific calculation method thereof may be defined by referring to the following:

RSRQ＝N*RSRP/RSSI

where N is the number of Resource Blocks (RBs) for RSSI measurement. RSRP is a linear average of the measured power (in watts, W) on the Resource Elements (REs) that carry the measurement reference signal (which may be CSI-RS or secondary synchronization signal SSS). The embodiment does not limit the RSRP calculation method, and may adopt a method of a current protocol, or adopt other methods. The RSSI is a linear average of the total received power over N RBs (including co-channel serving cell and non-serving cell interference, adjacent channel interference, thermal noise, etc.) used for measuring the RSSI in the OFDM symbol including the measurement reference signal resource within the measurement bandwidth and the measurement time. The definition of RSSI is merely an example description and is not limited to the manner described above.

The RSRQ calculation method will be described below by way of example.

The network equipment configures reference signal resource sets of [ CSI-RS resource # a, CSI-RS resource # b and CSI-RS resource # c ], and requires the terminal equipment to report RSRQ measurement results.

The terminal device measures Reference Signal Received Power (RSRP) of CSI-RS resource # a, CSI-RS resource # b, and CSI-RS resource # c, respectively.

The terminal device measures corresponding interference powers (RSSIs) of the CSI-RS resource # a, the CSI-RS resource # b and the CSI-RS resource # c, respectively, and calculates RSRQ.

Taking CSI-RS resource # a as an example, the specific measurement methods may be as follows:

1) the RSSI measurement of CSI-RS resource # a may be performed within the RB in which CSI-RS resource # a is located. The RSRQ of the CSI-RS resource # a is the ratio of the RSRP and the RSSI.

2) The RSSI measurement of the CSI-RS resource # a is carried out in the RB where the CSI-RS resource # a is located, interference power RSSIa is obtained, the number Na of the interfered RB resources is measured, RSSIb and RSSIc are obtained in the same way, and the number Nb and Nc of the interference RB resources are measured respectively. For CSI-RS resource # a, a plurality of RSRQs may be calculated, in this case RSRQa, b and RSRQa, c, which are the ratios of their RSRPs to other RSSIs in the set, for example:

RSRQ_a,b＝(N_a+N_b)*RSRP_a/(RSSI_a+RSSI_b)

RSRQ_a,c＝(N_a+N_c)*RSRP_a/(RSSI_a+RSSI_c)

or

RSRQ_a,b＝RSRP_a/(RSSI_a/N_a+RSSI_b/N_b)

RSRQ_a,c＝RSRP_a/(RSSI_a/N_a+RSSI_c/N_c)

For each measured RSRQ of CSI-rsresources, the UE may report together, or select one or more of them to report, and may also report and calculate an interference measurement resource CRI or RS-ID corresponding to the RSRQ.

3) The RSSI measurement of the CSI-RS resource # a is carried out in the RB where the CSI-RS resource # a is located, and the RSSI measurement of the interference power is obtained_aMeasuring the number of interfered RB resources N_aObtaining RSSI in the same way_bAnd RSSI_cMeasured RB numbers are respectively N_bAnd N_cIf so, the RSRQ of the CSI-RS resource # a is;

(N_a+N_b+N_c)*RSRP_a/(RSSI_a+RSSI_b+RSSI_c)

or

RSRP_a/(RSSI_a/N_a+RSSI_b/N_b+RSSI_c/N_c)

Note that the RSSI_b/cThe method may include the signal power of the reference signal resource b/c in the measurement set and the interference power on the measurement resource corresponding to the reference signal resource, may also include only the interference power on the measurement resource corresponding to the reference signal resource without including the signal power of the reference signal resource b/c in the measurement set, and may also include only the signal power of the reference signal resource b/c in the measurement set.

4) The RSSI of the CSI-RS resource # a is the sum of the signal powers of the reference signal resources within the measurement set other than the CSI-RS resource # a.

5) The RSSI measurement of the CSI-RS resource # a is measured on the RB where all reference signal resources in the [ CSI-RS resource # a, CSI-RS resource # b and CSI-RS resource # c ] are located; one possible solution is that the RSSI of CSI-RS resource # a should not contain the signal power of the reference signal resource in the measurement set; alternatively, the RSSI of the CSI-RS resource # a should contain the signal power of the reference signal resources in the measurement set other than CSI-RS resource # a. When the RBs where the resources in the reference signal resource set are overlapped, the N value during RSRQ calculation may correspond to the number of non-overlapping RBs occupied by the resource set, or may correspond to the sum of the number of RBs occupied by each resource in the resource set, that is, N is the number of RBs occupied by CSI-RS resource # a + the number of RBs occupied by CSI-RS resource # b + the number of RBs occupied by CSI-RS resource # c.

The interference measurement range may be an RB in which a single measurement resource is located, or may be a continuous bandwidth occupied by a single measurement resource (from an initial RB of a measurement resource to a continuous bandwidth containing all measurement resources), or a maximum value of the RB or continuous bandwidth occupied by all the single measurement resources in the resource set, or an RB or continuous bandwidth occupied by all the measurement resources in the resource set as a whole. The bandwidth may be measured in RB, RE, or Hz.

The above scheme describes an example of an RB where the measurement resource is located, and the same method can be extended to an RE, a symbol, and a sub-band where the measurement resource is located, and the corresponding number of the measurement resource can also be changed to the number of the corresponding RE, symbol, and sub-band. In addition, the number of measurement resources in each RSRQ may be eliminated. Or, like RSSI_x/N_xMay also be replaced by an integral quantity (e.g. an average amount of interference over the measurement resources).

And S505, the terminal equipment reports the RSRQ of a specific quantity to the network equipment according to the RSRQ reporting number configured by the network equipment or the RSRQ reporting number default to the protocol.

Assuming that the number of reports is k, one reporting method is to report k RSRQs (which may also include CRI or SSB index of measurement resources corresponding to the reported RSRQs) with the largest value to the network device. In another reporting mode, reporting of multiple RSRQs may adopt a differential reporting mode or other modes. A differential reporting method is characterized in that a field with the length of x bits is used for representing the maximum RSRQ, and fields with k-1 y bits are used for respectively representing the difference value between the residual k-1 RSRQ and the maximum RSRQ. The values of x and y are not limiting and can be any positive integer. The report of the RSRQ can be carried out by a PUSCH or PUCCH channel and adopting a specific report format. One possible reporting format is shown in table 8:

TABLE 8

The reporting format is only used for explaining the bit length of the field corresponding to each reported quantity, and does not limit the reported quantities to be reported together, nor the number of each reported quantity therein. The RSRQ field indicates one of the RSRQs (e.g., the maximum RSRQ), and the Differential RSRQ indicates the difference between the RSRQ and the maximum RSRQ.

The above methods are all described with the measurement resource being CSI-RS, but in practice, the measurement reporting method is not limited to CSI-RS resources, and when the measurement resource is SSB, the measurement reporting method may also be used.

According to the communication method provided by the embodiment of the application, the terminal device can measure the interference between the beams and report the interference to the network device in an RSRQ mode. Therefore, the beams with small interference can be selected for data transmission according to the RSRQ, and the performance of data transmission is improved.

Please refer to fig. 16, which is a flowchart illustrating another communication method according to an embodiment of the present application.

In this embodiment, the terminal device determines, according to the measurement configuration information, a type of the reported CRI (that is, the channel measurement resource CRI, the interference measurement resource CRI, or both of them are reported), and/or a number of the reported interference measurement resources CRI, and/or a resource set used for selecting the interference measurement resources CRI.

The reported CRI type and number can be indicated in a number of ways.

Specifically, the method comprises the following steps:

s601, the network equipment sends measurement configuration information to the terminal equipment, wherein the measurement configuration information comprises measurement resource configuration information and measurement reporting configuration information. The terminal device receives the measurement configuration information.

The configuration of the measurement resources can refer to the foregoing embodiments.

The measurement report configuration information includes information related to measurement report, including one or more of the following: the measurement report configures one or more associated resource sets, report amount, reported CRI type, reported interference measurement resource CRI quantity, and the like.

S602, the network equipment sends a reference signal to the terminal equipment according to the measurement configuration information. The terminal device receives the reference signal.

And S603, the terminal equipment determines the CRI reporting criterion according to the measurement configuration information.

The network equipment displays or implicitly indicates a CRI reporting criterion according to a certain field in the measurement configuration information, wherein the CRI reporting criterion comprises a reported CRI type, and/or a reported interference measurement resource CRI quantity, and/or a resource set selected by the interference measurement resource CRI.

Wherein the CRI type can be determined by one or more of the following:

1) the reported CRI type (channel measurement resource CRI, interference measurement resource CRI, or both reported) is determined by the CRI type indication field configured by the measurement configuration information. For example, the indication method shown in table 9 is adopted (the correspondence between the following field values and the field meanings may be arbitrary, and the following is only an example):

table 9 illustrates a CRI type determination method

2) And determining the reported CRI type by measuring the quantity of the measurement resource sets configured by the configuration information.

3) And indicating the CRI type to be reported based on the report quantity contained in the measurement report configuration. For example, the indication method shown in table 10 is used to indicate:

another CRI type determination method exemplified in table 10

Wherein cri denotes the NZP CSI-RS resource index used for channel measurement, crin denotes the NZP CSI-RS resource index comprising a plurality of NZP CSI-RS resource indexes which can be used for channel and interference measurement, and cri-intf denotes the NZP CSI-RS resource index used for interference measurement. Here, the three abbreviated forms of cri, crin, and cri-intf are merely examples for explaining the above three functions, and the specific representation is not limited to the three abbreviated forms.

The number of interference measurement resources CRI included in the interference measurement result is one or more; determining the number of interference measurement resources, CRIs, to be reported by one or more of the following methods:

1) and the CRI quantity indication field configured based on the measurement configuration information indicates or determines the reported CRI quantity. For example, a number of channel measurement resources CRI to be reported, or a number of interference measurement resources CRI, or a sum of the numbers of the channel measurement resources CRI and the interference measurement resources CRI is indicated by a number of CRI field; or the number of interference measurement resources CRI to be reported is indicated by the number of channel measurement resources CRI, for example, for each channel measurement resource CRI, at most k corresponding interference measurement resources CRI are reported, k may be any positive integer.

2) The number of resource setting configured based on the measurement configuration information implicitly indicates the CRI type to be reported, and/or the number of interference measurement resources CRI to be reported, and/or the resource setting selected for the interference measurement resources CRI. For example, when the type of the measurement reporting configuration is aperiodic and the number of associated resource setting is x, the ith (i < ═ x) resource setting is used for selecting the interference measurement resource CRI; or the type of the measurement reporting configuration is periodic or semi-static, and when the number of the associated resource setting is y, the jth (j < ═ y) resource setting is used for selecting the interference measurement resource CRI; or when the number of resource setting associated with the measurement reporting configuration is z, the kth (k < ═ z) resource setting is used for selecting the interference measurement resource CRI. x, y, z may be any positive integer.

3) And indicating the number of the interference measurement resources CRI to be reported based on the resource number in the resource setting selected for the interference measurement resources CRI. For example, when the resource number in the resource setting selected for the interference measurement resource CRI is K, reporting all the K interference measurement resources CRI, and reporting the K interference measurement resources CRI in a sorted manner according to the interference strength. Or only K (K < K) interference measurement resources CRI are reported, K being calculated by K.

4) And determining the number of the interference measurement resources CRI to be reported by measuring the reporting quantity configured by the configuration information.

In addition, if the interference measurement resource CRI needs to be reported, the measurement resource set selected by the interference measurement resource CRI is determined according to the measurement resource set quantity configured by the measurement configuration information. Specifically, the terminal device may select one or more interference resources from corresponding pilot resources to report in one or more of the following manners:

selecting CRI of k interference resources causing strongest interference to channel resources as reported interference measurement resource CRI;

selecting CRI of k interference resources causing the weakest interference to channel resources as reported interference measurement resource CRI;

the CRI of k interference resources with strongest signal energy received by a receiving beam of the channel resource (specified by QCL relationship) is used as a reported interference measurement resource CRI;

the CRI of k interference resources with the weakest signal energy received by a receiving beam of the channel resource (specified by QCL relationship) is used as a reported interference measurement resource CRI;

and selecting the CRI of all configured interference resources as the reported interference measurement resource CRI.

And S604, the terminal equipment determines a reporting mode of the CRI according to the measurement configuration information and reports the CRI.

When a plurality of CRIs need to be reported, each CRI in the reporting format can be arranged according to a protocol default rule or a mode of displaying a notification by a network device through a high-level signaling.

For example, when a plurality of interference measurement resources CRI need to be reported, the reporting may be ordered according to interference strength. The sorting mode can be ascending or descending. Specifically, the terminal device reports k interference measurement resources CRI in k fields, the interference strength of the interference measurement resource CRI represented by the first field is strongest, and the interference strengths of the interference measurement resources CRI represented by subsequent fields are sequentially reduced; or the interference strength of the interference measurement resource CRI represented by the first field is weakest, and the interference strength of the interference measurement resource CRI represented by the subsequent fields is sequentially enhanced.

For another example, when multiple channel measurement resources CRI need to be reported, each channel measurement resource CRI in the reporting format may be reported in order of channel quality (e.g., CQI/RSRP/RSSI/SINR/SNR size). The sorting mode can be ascending or descending. For example, the terminal device reports k channel measurement resources CRI in k fields, the channel quality of the channel measurement resource CRI indicated by the first field is the best, and the channel quality of the channel measurement resource CRI indicated by the subsequent fields is reduced in sequence; or the channel quality of the channel measurement resource CRI indicated by the first field is the worst, and the channel quality of the channel measurement resource CRI indicated by the subsequent field is enhanced in turn.

When the channel measurement resource CRI and the interference measurement resource CRI are reported together, the reporting format may be reported according to a channel-first and interference-second ordering manner, or an interference-first and channel-second ordering manner, or a channel-interference-channel-interference intersection manner. For example, to report x channel measurement resources CRI and y interference measurement resources CRI, x channel measurement resources CRI may be arranged first and then y interference measurement resources CRI are arranged in the report format, or y interference measurement resources CRI may be arranged first and then x channel measurement resources CRI are arranged, or the x channel measurement resources CRI and the y interference measurement resources CRI are arranged in a cross manner, for example, each channel measurement resource CRI and its corresponding interference measurement resource CRI are continuously arranged as a group CRI, and each group CRI is continuously arranged according to a group.

Reporting of one or more CRI may be performed via a PUSCH or PUCCH channel, using a specific reporting format. One possible reporting format is shown in table 11:

TABLE 11

The reporting format is only used for explaining the bit length of the field corresponding to each reported quantity, and does not limit the reported quantities to be reported together, nor the number of each reported quantity therein. Wherein the channel measurement resource CRI corresponds

Refers to the number of resources in some or all of the configured resource setting for channel measurement, or the number of resources in some or all of the configured resource sets for channel measurement. Wherein interference measurement resource CRI corresponds

Refers to the number of resources in some or all of the configured resource setting for interference measurement, or the number of resources in some or all of the configured resource sets for interference measurement.

The above methods are all described by taking the measurement resource as CSI-RS, and the reported interference ID is the interference measurement resource CRI. In practice, the measurement reporting method is not limited to CSI-RS resources, and the measurement resources may be SSBs. And when the resource is measured, the corresponding reported quantity is the channel measurement resource CRI, the channel SSB-index and the interference SSB-index when the resource is interfered.

According to the communication method provided by this embodiment, the terminal device may report one or more interference measurement resources CRI and/or channel measurement resources CRI, which is convenient for the network device to identify the interference strength of each beam to the channel, thereby avoiding mutual interference between beams and improving the performance of data transmission.

Please refer to fig. 17, which is a flowchart illustrating another communication method according to an embodiment of the present application.

In this embodiment, one or more CQIs of a certain type or multiple types may be reported. The type of CQI reported and the number of CQIs may be determined in a variety of ways.

Specifically, the method may comprise the steps of:

s701, the network equipment sends measurement configuration information. The measurement configuration information comprises measurement resource configuration information and measurement reporting configuration information. The terminal device receives the measurement configuration information.

The configuration of the measurement resources can refer to the foregoing embodiments, and is not described herein again.

The measurement report configuration information includes information related to measurement report, including one or more of the following: the measurement reporting configuration is associated with one or more measurement resource sets, a channel state information measurement indication (csimasurementindex), a report quality (report quality), a reported CQI number, and the like. Here, the channel state information may be CQI or SINR. The measurement reporting configuration information may also include other information, not limited to the ones listed herein. The channel state information measurement indicates a calculation method for indicating CQI and/or SINR employed by the terminal device.

S702, the network equipment sends a reference signal according to the measurement configuration information. The terminal device receives the reference signal.

S703, the terminal device determines a CQI and/or SINR calculation criterion according to the channel measurement indication field, the measurement resource set number and/or the reported quantity in the measurement configuration information, and calculates the CQI and/or SINR. In the following, the CQI is taken as an example to illustrate a specific CQI calculation criterion, and the calculation criterion described below is also applicable to SNR calculation and reporting.

Specifically, one or more of the following methods may be employed:

1) and indicating resources for CQI calculation in a display mode based on a channel state information measurement indication field contained in the measurement reporting configuration. For example, the indication method shown in table 12 may be employed:

TABLE 12

2) And determining resources for CQI calculation based on the reported quantity contained in the measurement reporting configuration. For example, the indication method shown in table 13 is employed:

watch 13

3) And determining resources for CQI calculation based on the number of measurement resource sets associated with the measurement reporting configuration. . Specifically, one or more of the following methods may be employed:

when the number of the resource sets associated with the measurement reporting configuration is greater than 3 (for example, 4), calculating CQI based on the first three resource sets; specifically, the first resource set is used for channel measurement, the second resource set is used for CSI-IM based interference measurement, and the third resource set is used for NZP CSI-RS based interference measurement; all the other resource sets are not used for reporting CQI calculation, and the specific other resource sets can be used for interference resource identification measurement;

further, the CQI calculation method based on the specified resource set may adopt a default rule, or may be notified by the network device through high-layer signaling. For example,

when calculating n (n > ═ 1) CQIs based on one NZP CSI-RS resource set, the terminal device may select the y-th resource in the x-th resource set in the resource set as a channel measurement resource and an interference measurement resource by default to calculate CQIs; the terminal device may also select the y-th resource in the x-th resource set in the resource set as a channel measurement resource by default, and calculate the CQI by using one or more other resources in the resource set as an interference measurement resource;

when calculating n (n > ═ 1) CQIs based on one NZP CSI-RS resource set and one CSI-IM resource set, the terminal device may select the y-th resource in the x-th resource set in the resource set as a channel measurement resource by default, and one or more resources contained in the CSI-IM resource set are used as interference measurement resources to calculate CQIs; the terminal device may also select the y-th resource in the x-th resource set in the resource set as a channel measurement resource by default, and one or more resources in the resource set and one or more resources contained in the CSI-IM resource set are used as interference measurement resources to calculate the CQI.

When calculating n (n > ═ 1) CQIs based on the two NZP CSI-RS resource sets, the terminal device may select, by default, the y-th resource in the x-th resource set in one of the resource sets as a channel measurement resource, and calculate CQIs using one or more resources included in the other resource set as interference measurement resources;

when calculating n (n > ═ 1) CQIs based on two NZP CSI-RS resource sets and one CSI-IM resource set, the terminal device may select the y-th resource in the x-th resource set in one of the resource sets as a channel measurement resource by default, and calculate the CQI by using one or more resources included in the other two resource sets as an interference measurement resource.

The pilot resources measured by the above CQI calculation may be derived from one or more resource sets, or one or more resources.

The resource for interference measurement and the resource for channel measurement may be the same resource belonging to the same resource set or resource set, may also be different resources belonging to the same resource set or resource set, and may also be different resources belonging to different resource sets or resource sets;

the multiple resources for interference measurement may belong to the same resource set or resource set (resource set), or may belong to different resource sets or resource sets (resource sets). It should be noted that the above criterion for calculating CQI may also be used for calculating SINR.

S704, the terminal equipment determines the quantity of CQI to be reported according to the measurement reporting configuration and reports the CQI.

Specifically, the terminal device may display, according to a CQI report number indication field in the measurement report configuration, a CQI number indicating the number of CQIs to be reported. The terminal device may also determine the number of CQIs to be reported according to the number of resources included in the configured resource setting for channel measurement.

When reporting multiple CQIs, the pilot resources measured by multiple CQI calculations may originate from the same resource of the same resource set or resource set, may originate from different resources of the same resource set or resource set, or may originate from different resources of different resource sets or resource sets;

the CQIs based on the same resource set or the same resources of the resource set may be CQI values measured by using a plurality of resources as channel measurement resources and as interference measurement resources, respectively; specifically, when 2 CQIs are reported, a first CQI value is generated based on the channel measurement of resource # a and the interference measurement of resource # b, and a second CQI value is generated based on the channel measurement of resource # b and the interference measurement of resource # a.

The multiple CQIs based on different resources of the same resource set or resource set may be CQI values measured by using multiple resources as channel measurement resources and all the other resources as interference measurement resources, respectively; specifically, when 2 CQIs are reported, a first CQI value is generated based on channel measurement of resource # a and interference measurement based on (resource # b, resource # c), and a second CQI value is generated based on channel measurement of resource # b and interference measurement based on (resource # a, resource # c).

The CQI values of the different resources based on the different resource sets or resource sets may be CQI values measured for the interference measurement resources based on multiple resources (resource # a, resource # b) of the same resource set respectively as the channel measurement resources and the resources (resource # c, resource # d) of other resource sets; specifically, when 2 CQIs are reported, a first CQI value is generated based on channel measurement of resource # a and interference measurement based on (resource # c, resource # d), and a second CQI value is generated based on channel measurement of resource # b and interference measurement based on (resource # c, resource # d).

When reporting the CQI, the CRI of the interference resource adopted by the CQI calculation can be reported simultaneously, and the CQI can also be reported independently.

When reporting multiple CQIs, a differential reporting method may be employed. Assuming that the number of CQIs to be reported is k, one differential reporting is to represent the maximum CQI by a field of x bits, and to represent the difference between the remaining k-1 CQIs and the maximum CQI by fields of k-1 y bits, respectively, where the values of x and y are not limited and may be any positive integer.

The CQI may be reported in a specific reporting format via a PUSCH or PUCCH channel. One possible reporting format is shown in table 14 below:

TABLE 14

The reporting format is only used for explaining the bit length of the field corresponding to each reported quantity, and does not limit the reported quantities to be reported together, nor the number of each reported quantity therein. Wherein, the CQI field indicates one of the CQIs (e.g., the CQI with the largest value), and the Differential CQI indicates the difference between the CQI and the other CQIs. Wherein the channel measurement resource CRI corresponds

Refers to the number of resources in some or all resource sets configured for channel measurement, or the number of resources in some or all resource sets configured for channel measurement. Wherein interference measurement resource CRI corresponds

Refers to the number of resources in some or all resource sets configured for interference measurement, or the number of resources in some or all resource sets configured for interference measurement.

The above methods are all described with the measurement resource being CSI-RS, but actually, the measurement reporting method is not limited to CSI-RS resources, and when the measurement resource is SSB, the method may also be used to perform measurement reporting of CQI.

According to the communication method provided by the embodiment, the network equipment can flexibly instruct the terminal equipment to calculate the CQI according to a specific method, so that the network equipment can obtain different types of CQI for different purposes. For example, the network device may obtain a CQI without intra-cell interference for interference avoidance scheduling, or obtain a CQI accounting for specific beam interference for specific beam pairing scheduling, so that the network device may adapt to different data transmission scenarios by using different schedules, thereby improving data transmission performance.

The above description for CQI also applies to SINR; specifically, a signal-to-noise and interference ratio (SINR) is determined based on the received power of the channel measurement resource and the interference and noise power of the interference measurement resource, and the CQI value is an mcs (modulation and code scheme) indication corresponding to the SINR.

Please refer to fig. 18, which is a flowchart illustrating another communication method according to an embodiment of the present application.

In this embodiment, the terminal device reports the channel measurement resource CRI, the interference measurement resource CRI, and the CQI. The network equipment can perform interference avoidance scheduling according to the channel measurement resource CRI, the interference measurement resource CRI and the CQI, and improve the data transmission performance.

The CRI and CQI calculation criteria can refer to the foregoing embodiments.

Specifically, the method may comprise the steps of:

s801, the network equipment sends measurement configuration information. The measurement configuration information comprises measurement resource configuration information and measurement reporting configuration information. The terminal device receives measurement configuration information.

The measurement report configuration information includes information related to measurement report, including one or more of the following: the measurement reporting configuration is associated with one or more resource sets, a channel state information measurement indicator (csimasurementindicator), a reporting amount (report qualification), and the like. The measurement report information may also include other information, not limited to the ones listed herein.

S802, the network equipment sends a reference signal according to the measurement configuration information. The terminal device receives the reference signal.

S803, the terminal device determines, according to the measurement report configuration information, a report channel measurement resource identifier (may be CRI or SSB-index), an interference resource identifier (may be CRI or SSB-index), and a CQI, and may also report one or more of the following measurement quantities: RSRP, RSSI, SINR, CQI, PMI, LI, RI, il.

Specifically, one or more of the following measurement and reporting behaviors may be decided by measuring information (e.g., channel state information measurement indication, reporting amount information) included in the reporting configuration information or in other implicit manners: whether to report a plurality of resource identifiers, the type of each resource identifier (which may be a channel measurement resource identifier or an interference resource identifier), a CQI calculation criterion, an SINR calculation criterion, and the like.

In the following, CQI is taken as an example, and the description of CQI calculation and reporting is also applicable to SNR calculation and reporting.

1) Determining one or more of the following measurement and reporting behaviors based on a channel state information measurement indication contained in measurement reporting configuration information: whether to report a plurality of resource identifiers, meaning of each resource identifier (which may be a channel measurement resource identifier or an interference resource identifier), and a calculation method of reporting the CQI, for example, an indication method shown in table 15 is adopted:

watch 15

Specifically, the resource identifier may be a CRI or an SSB-index; the reported channel measurement resource CRI and the interference measurement resource CRI may be one or multiple, and the specific number of reported CRIs may be indicated by the network device through a high-layer configuration signaling (for example, a new field "NumofCRI" is defined in the reporting configuration information) or through another implicit manner (for example, an uplink resource format for reporting measurement feedback in the reporting configuration information).

The details of the above CQI calculation method (method one, method two, and method three) are as follows:

the method comprises the following steps:

when the measurement resource configuration is that two resource setting are configured for a user, the first resource setting is used for channel measurement, and the second resource setting is used for interference measurement;

when the measurement resource configuration is that three resource setting are configured for the user, the first resource setting is used for channel measurement, the second resource setting is used for CSI-IM based interference measurement, and the third resource setting is used for NZP CSI-RS based interference measurement.

The second method comprises the following steps:

when the measurement resource configuration is that two resource setting are configured for a user, the first resource setting is used for channel measurement, and the second resource setting is used for reporting resource identification measurement and interference measurement;

when the measurement resource configuration is that three resource setting are configured for a user, the first resource setting is used for channel measurement, the second resource setting is used for CSI-IM based interference measurement, and the third resource setting is used for NZP CSI-RS based interference measurement and reporting resource identification measurement.

The third method comprises the following steps:

when the measurement resource configuration is that two resource setting are configured for a user, the first resource setting is used for channel measurement and interference measurement, and the second resource setting is used for reporting resource identification measurement;

when the measurement resource configuration is that three resource setting are configured for a user, the first resource setting is used for channel measurement, the second resource setting is used for CSI-IM based interference measurement, and the third resource setting is used for NZP CSI-RS based reporting resource identification measurement.

The method four comprises the following steps:

when the measurement resource configuration is that four resource setting are configured for a user, the first resource setting is used for channel measurement, the second resource setting is used for CSI-IM based interference measurement, the third resource setting is used for NZP CSI-RS based interference measurement, and the fourth resource setting is used for reporting resource identification measurement.

2) Deciding one or more of the following measuring and reporting behaviors based on the number of Resource settings associated with the measurement reporting configuration: whether to report a plurality of resource identifiers, meaning of each resource identifier (which can be a channel measurement resource identifier or an interference resource identifier), and a calculation method of reporting CQI. For example, when the number of Resource setting associated with the measurement reporting configuration is 4, reporting one or more interference measurement resources CRI; and calculating and reporting the CQI based on the method four.

3) Deciding one or more of the following measurement and reporting behaviors based on the number of resources associated with the measurement reporting configuration: whether to report a plurality of resource identifiers, meaning of each resource identifier (which can be a channel measurement resource identifier or an interference resource identifier), and reporting a CQI calculation method; for example, when Resource setting for channel measurement only contains one Resource and the corresponding Resource only contains one Resource, reporting an interference measurement Resource CRI; the Resource setting associated with the reporting configuration may be one or more, and the Resource setting used for reporting the Resource identifier measurement may be CSI-IM or NZP CSI-RS; the reporting configuration type can be non-periodic (AP), periodic (AP) or semi-Static (SP); the CQI may be calculated by method one, method two, method three, or method four.

The method for determining the interference resource identifier can be independently decided by a terminal, and can also be notified by network equipment through high-level signaling display; for example, the terminal device may autonomously decide which interference resource identifiers to report based on the following methods:

1) selecting j interference resource identifiers with strongest interference;

based on the interference measurement of the interference measurement resource CRI and the SINR obtained by the channel measurement of the channel measurement resource, the SNR obtained by comparing with the channel measurement resource independently is decreased by an interference resource ID which is larger than a certain threshold; or

And based on the MCS corresponding to the SINR obtained by the interference measurement of the interference measurement resource CRI measurement resource and the channel measurement of the channel measurement resource, the MCS corresponding to the SNR obtained by the channel measurement resource alone is reduced by more than a certain threshold of the interference resource ID.

2) Selecting j interference resource identifiers with weakest interference;

Wherein the value of j is greater than or equal to 1 and less than or equal to the number of configured interference measurement resources. That is, at least one resource identifier can be reported, and at most all resource identifiers can be reported.

S804, the terminal equipment reports the resource identifiers of the specific quantity to the network equipment according to the measurement reporting configuration configured by the network equipment.

The resource identifiers can be reported in a default mode, or in a specific mode of high-level signaling display notification by the network equipment; the reporting of the multiple resource identifiers may be ordered according to the interference strength to the channel measurement resource (the ordering may be in an increasing order or a decreasing order), may adopt a differential reporting mode, or other methods. Each resource identifier corresponds to a field with the length of x bits, and the bit length corresponding to each resource identifier can be the same or different; the reporting of the multiple resource identifiers can be carried out by adopting a specific reporting format through a PUSCH or PUCCH channel.

One possible reporting format is shown in table 16 below:

TABLE 16

The reporting format is only used for explaining the bit length of the field corresponding to each reported quantity, and does not limit the reported quantities to be reported together, nor the number of each reported quantity therein. Wherein, the CRI field indicates one of the resource identifications (e.g. channel measurement resource identification), and the Differential CRI indicates the difference value between the resource identification and other resource identifications.

The resource identifier may be a CRI or an SSB-index; when only one resource identifier is reported, the resource identifier can be a channel measurement resource identifier or an interference resource identifier; the reported n (n > -2) resource identifiers may be n channel measurement resource identifiers, or n interference resource identifiers, or a combination of k (k > -1) channel measurement resource identifiers and j (j > -1) interference resource identifiers, where k + j ═ n.

According to the communication method provided by the embodiment, the network device can simultaneously indicate the interference measurement resource CRI reporting criterion and the CQI or SINR calculating criterion with little configuration overhead to acquire specific CRI information and CQI or SINR information.
