Description

Channel state information acquisition method and related equipment

Technical Field

The present application relates to the field of communications technologies, and in particular, to a method for acquiring channel state information and a related device.

Background

The fifth generation mobile communication system (5 th generation, 5G) adopts high frequency communication, and one of the main problems of the high frequency communication is that the signal energy is sharply reduced along with the transmission distance, so that the signal transmission distance is short. In order to overcome the problem, the high-frequency communication adopts an analog beam technology, and the large-scale antenna array is used for weighting processing, so that the signal energy is concentrated in a smaller range to form a signal similar to a light beam, and the transmission distance is increased. The communication method using the beam can solve the problem of short transmission distance, but also faces the problem that the high frequency signal is easily blocked and the signal intensity attenuation is large. In order to solve the problem, a multi-beam joint transmission mode can be adopted, so that a plurality of beams can serve one terminal, and the influence on the transmission performance due to signal attenuation of a single beam is avoided.

The multi-beam joint transmission approach requires the base station to select appropriate transmission parameters based on the channel state information of multiple beams. However, in the current channel measurement mode, the channel state information is obtained by the terminal device by measuring the resources configured for each beam, that is, the channel state information of each resource reported by the terminal device cannot support the multi-beam joint transmission mode well. Therefore, how to perform joint measurement on resources respectively configured by multiple beams is an urgent problem to be solved.

Disclosure of Invention

The application provides a method and related equipment for acquiring channel state information, which are beneficial to performing joint measurement on a plurality of resources, resource sets or resource configuration to acquire corresponding channel state information.

In a first aspect, the present application provides a method for acquiring channel state information, where in the acquiring method, a network device may send first measurement configuration information to a terminal device, and then the network device may receive the first channel state information sent by the terminal device according to the first measurement configuration information. Wherein, the first measurement configuration information comprises a first resource configuration and a first reporting configuration; the first resource configuration comprises a first identifier and a second identifier; the first identifier is used for indicating the first resource configuration, the first resource set or the first resource; the second identifier is used to indicate a second resource configuration, a second resource set, or a second resource. Wherein the first resource configuration, the first resource set, or the first resource is associated with the second resource configuration, the second resource set, or the second resource, respectively. Therefore, based on the association relationship, it is beneficial for the terminal device to jointly determine the channel state information for multiple resource configurations, resource sets and/or resources.

In this application, a terminal device is a device with communication functionality, which may also be referred to as a terminal, and may include a handheld device with wireless communication functionality, a vehicle-mounted device, a wearable device, a computing device or other processing device connected to a wireless modem, etc. The terminal devices in different networks may be called different names, for example: a terminal, a User Equipment (UE), a mobile station, a subscriber unit, a station, a cellular telephone, a personal digital assistant, a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless telephone, a wireless local loop station, etc. The terminal equipment can be referred to as a wireless terminal and a wired terminal. The wireless terminal may refer to a device that provides voice and/or data connectivity to a user, a handheld device having wireless connection capability, or other processing device connected to a wireless modem that may communicate with one or more core networks via a Radio Access Network (RAN).

Referring to fig. 1, fig. 1 is an architecture diagram of a communication system according to an embodiment of the present disclosure. Specifically, as shown in fig. 1, the communication system may include a terminal device and a network device, and the terminal device and the network device may communicate through the communication system. In order to increase the signal transmission distance, the terminal device and the network device may use a beam mode to concentrate the signal energy in a smaller range, so as to form a signal similar to a light beam, thereby increasing the transmission distance.

At present, based on the communication system shown in fig. 1, in the transmission of a downlink signal, a network device selects, through a beam management process, multiple beams with better quality for use in communication between the network device and a terminal device, but because a channel state changes faster in a communication process, when the multiple beams are used, the network device further needs to configure measurement configuration information for the multiple beams, so that the terminal device can calculate and report channel state information of each beam based on the measurement configuration information, and thus, the network device can select an appropriate transmission parameter based on the channel state information of each beam to perform data transmission.

Therefore, the present application provides a method for acquiring channel state information, where there is an association relationship between resource allocation, resource set, resource or reporting configuration in multiple measurement configuration information configured by a network device. For example, the network device sends first measurement configuration information to the terminal device, where a first resource configuration in the first measurement configuration information may include a first identifier and a second identifier; the first resource allocation, the first resource set or the first resource indicated by the first identifier is respectively associated with the second resource allocation, the second resource set or the second resource indicated by the second identifier. Therefore, through the associated resource allocation, resource set, resource or reporting allocation, the associated resource allocation, resource set, resource or reporting allocation is beneficial to jointly determining the channel state information by the terminal equipment.

The following explains the method for acquiring the channel state information with reference to the drawings.

Herein, the first, second, third, fourth and various numerical numbers are merely for convenience of description and are not intended to limit the scope of the embodiments of the present invention.

Herein, the first measurement configuration information, the second measurement configuration information, the third measurement configuration information, the fourth measurement configuration information, and the fifth measurement configuration information all include two parts, which are resource configuration and reporting configuration, respectively. As shown in fig. 2, the measurement configuration information configured for the beam 1 and the beam 2 by the network device includes resource configuration ResourceConfig and reporting configuration ReportConfig. The Resource configuration is related to measurement resources, one Resource configuration ResourceConfig may include one or more Resource sets, one Resource set may include one or more Resource sets, and one Resource is an independent configuration unit and includes parameters related to a measurement signal sent by a network device to a terminal device, such as a type, a time-frequency position, and a period of the measurement signal. The reporting configuration is a relevant configuration related to reporting of the channel state information, that is, reporting the channel state information measured based on the resource in the resource configuration based on what criteria, such as reporting content, reporting period, reporting resource, and the like. The reporting configuration is associated with a specific resource configuration to indicate that the reported channel state information is obtained by measuring resources in the resource configuration based on the reporting configuration.

The Channel state information includes one or more of a Rank Indicator (RI), a Precoding Matrix Indicator (PMI), a Channel Quality Indicator (CQI), a Reference Signal Receiving Power (RSRP), and a Signal to Interference plus Noise Ratio (SINR) of a Channel.

Referring to fig. 3a, fig. 3a is a schematic flowchart illustrating a method for acquiring channel state information according to an embodiment of the present disclosure. As shown in fig. 3a, the method for acquiring channel state information may include the following steps:

101. the network equipment sends first measurement configuration information to the terminal equipment; the terminal equipment receives first measurement configuration information sent by the network equipment.

Wherein the first measurement configuration information includes: a first resource allocation and a first reporting allocation. The first resource configuration comprises a first resource set, the first resource set comprising a first resource; the second resource configuration includes a second set of resources, the second set of resources including a second resource. The first resource configuration comprises a first identifier and a second identifier; wherein the first identifier is used for indicating a first resource configuration, a first resource set or a first resource; the second identifier is used for indicating a second resource configuration, a second resource set or a second resource; the first resource configuration, the first resource set or the first resource indicated by the first identifier is respectively associated with the second resource configuration, the second resource set or the second resource indicated by the second identifier.

102. The terminal equipment sends first channel state information to the network equipment according to the first measurement configuration information; the network equipment receives first channel state information sent by the terminal equipment.

It can be seen that, in the method for acquiring channel state information shown in fig. 3a, the network device can notify the terminal device of the association between the two resource configurations, resource sets, or resources, so that it is beneficial for the terminal device to jointly determine the channel state information for the two resource configurations, resource sets, or resources.

Referring to fig. 3b, in the method for acquiring channel state information shown in fig. 3b, compared with fig. 3a, in 101, the network device may further send second measurement configuration information to the terminal device, where the second measurement configuration information includes a second resource configuration and a second reporting configuration; correspondingly, the terminal device receives the second measurement configuration information, and in 102, the terminal device further sends second channel state information to the network device according to the second measurement configuration information.

Wherein, the first RI in the first channel state information is the same as the second RI in the second channel state information.

It can be seen that in the method for acquiring channel state information shown in fig. 3b, the network device configures the first resource configuration, the first resource set, or the first resource in the first resource configuration, associates with the second resource configuration, the second resource set, or the second resource, and the RI in the first channel state information and the RI in the second channel state information reported by the terminal device are the same, so that it is beneficial to selecting the same data stream when the beams corresponding to the two measurement configuration information transmit the same data, and it is beneficial to improving the transmission performance of the channel.

In the following embodiment of the present application, a network device notifies a terminal device of possible implementation manners of the first resource configuration, the first resource set, or the first resource, which are respectively associated with a second resource configuration, a second resource set, or a second resource, through that a first resource configuration includes a first identifier and a second identifier; and the terminal device determines possible implementation manners of the first channel state information and the second channel state information, and relevant explanation is made. In the embodiment of the present application, a beam 1 configures first measurement configuration information, and a beam 2 configures second measurement configuration information. In the present application, the naming of the field, such as Association relationship, and the naming of the first indication information, such as Association Pattern, are only used for illustrative purposes, and are not used to limit the specific naming of these contents, and the actual naming of the field, the first indication information, and the like may be in other naming manners.

1.1, the first identifier is used for indicating a first resource configuration; the second identifier is used for indicating a second resource configuration; the first resource configuration and the second resource configuration are associated;

in the embodiment of the present application, in the first measurement configuration information, the first reporting configuration is configured to report first channel state information determined according to the first resource configuration; in the second measurement configuration information, the second reporting configuration is configured to report second channel state information determined according to the second resource configuration.

In the following, an alternative embodiment of how the network device notifies the terminal device of the association relationship between the first resource configuration and the second resource configuration is described.

In an optional implementation manner, the manner in which the network device notifies the terminal device of the association relationship between the first resource configuration and the second resource configuration may be: the first resource configuration comprises a first identifier and a second identifier; the first identification is used for indicating a first resource configuration; the second identifier is used for indicating an identifier of a second resource configuration associated with the first resource configuration. For example, as shown in fig. 4a, the first identifier idoffourceconfig 1 and the second identifier idoffourceconfig 2 are included in the first resource configuration ResourceConfig1, where the ideofresourceconfig 2 is an identifier of the second resource configuration. In this way, the terminal device may determine that the first resource configuration is associated with the second resource configuration according to the first identifier and the second identifier in the first resource configuration.

In another optional implementation manner, the manner in which the network device notifies the terminal device of the association relationship between the first resource configuration and the second resource configuration may also be: the first resource configuration includes a first identifier and an association field, and the association field includes the second identifier. For example, as shown in fig. 4b, the first resource configuration ResourceConfig1 includes a first identifier idofffig 1 and an association relationship field associationrelationship; the association relation field includes a second identifier IDofResourceConfig2, and the ideofresourceconfig 2 is an identifier of the second resource configuration, so that the terminal device can determine that the first resource configuration is associated with the second resource configuration. That is, the association field is used to indicate that the resource configuration identified by the identifier contained therein is associated with the first resource configuration identified by the first identifier.

How to determine the first channel state information and the second channel state information when the first resource configuration is associated with the second resource configuration is described below. For example, a first RI, a first PMI, a first CQI, and a first SINR in the first channel state information have a corresponding association with a second RI, a second PMI, a second CQI, and a second SINR in the second channel state information, respectively. The association manner is a constraint relationship between the first channel state information and the second channel state information respectively corresponding to the resource configuration having the association relationship.

In an optional implementation manner, the determining, by the terminal device, the same first RI and second RI includes: the terminal equipment respectively calculates a fifth RI which can be supported by the first resource configuration and a sixth RI which can be supported by the second resource configuration; and the terminal equipment determines a uniform RI according to the fifth RI and the sixth RI, and the uniform RI is used as the first RI and the second RI. Wherein, the terminal device determines a uniform RI according to the fifth RI and the sixth RI, including: the terminal equipment determines a maximum value from the fifth RI and the sixth RI as a uniform RI; or the terminal equipment determines a minimum value from the fifth RI and the sixth RI as a uniform RI; or, the terminal device determines a value between the fifth RI and the sixth RI, for example, an average value of the fifth RI and the sixth RI as a uniform RI; and so on.

In another optional embodiment, the first PMI and the second PMI are determined based on the same RI value, and the first channel state information includes the first PMI; the second channel state information includes the second PMI. That is, the terminal device may determine a PMI selection range based on the same RI value, for example, the determined first RI and second RI, and select a first PMI for the first resource configuration and a second PMI for the second resource configuration from the PMI selection range, respectively.

In yet another optional embodiment, a first PMI and a second PMI are orthogonal, and the first channel state information includes the first PMI; the second channel state information includes the second PMI. That is, the terminal device may determine the first PMI selection range according to the first resource configuration; determining a second PMI selection range according to the second resource configuration; the first PMI selected by the terminal device from the first PMI selection range is orthogonal to the second PMI selected from the second PMI selection range.

In yet another alternative embodiment, the first CQI and the second CQI are determined based on the same RI value, and the first channel state information includes the first CQI; the second channel state information includes the second CQI. That is, the terminal device calculates a first CQI for the first resource configuration and a second CQI for the second resource configuration based on the same RI value, such as the first RI and the second RI described above.

In yet another optional embodiment, the first SINR and the second SINR are determined based on the same RI value, and the first channel state information includes the first SINR; the second channel state information includes the second SINR. That is, the terminal device calculates a first SINR for the first resource configuration and a second SINR for the second resource configuration based on the same RI, such as the first RI and the second RI described above.

In yet another optional implementation manner, the network device may further explicitly notify the terminal device of the association manner of the first channel state information and the second channel state information. For example, the first resource configuration further includes first indication information, where the first indication information is used to indicate one or more of the following information: the first and second RIs are the same; the first PMI and the second PMI are determined based on the same RI value; the first PMI and the second PMI are orthogonal; the first CQI and the second CQI are determined based on the same RI value; and, the first SINR and the second SINR are determined based on the same RI value.

Optionally, the association relation field in the first resource configuration may include the second identifier and the first indication information. For example, as shown in fig. 4c, compared with fig. 4b, the association relation field further includes first indication information AssociationPattern1. As can be seen, in this embodiment, the terminal device may determine, according to the association relation field, the resource configuration associated with the first resource configuration, and the association manner between the first channel state information of the first resource configuration and the channel state information of the associated resource configuration.

How the first indication information indicates one or more of the above information is exemplarily set forth below. The first indication information may be a value field, and each specific value represents one or more specific association modes.

For example, if the value of the first indication information is A1, the first indication information represents RI association, and the first indication information is used to indicate at least one of the following information: the first RI and the second RI are the same, the first PMI and the second PMI are determined based on the same RI value, the first PMI and the second PMI are orthogonal, the first CQI and the second CQI are determined based on the same RI value, and the first SINR and the second SINR are determined based on the same RI value.

For another example, if the value of the first indication information is A2, the PMI association is indicated, and the first indication information is used to indicate at least one of the following information: the first PMI and the second PMI are determined based on the same RI value, and the first PMI and the second PMI are orthogonal.

For another example, if the value of the first indication information is A3, the CQI is associated, and the first indication information is used to indicate that the first CQI and the second CQI are determined based on the same RI value.

For another example, if the value of the first indication information is A4, which indicates SINR association, the first indication information is used to indicate that the first SINR and the second SINR are determined based on the same RI value.

For another example, when the value of the first indication information is A5, the first indication information indicates that the RI, the PMI, and the CQI are related, that is, the first indication information indicates that the first RI and the second RI are the same, the first PMI and the second PMI are determined based on the same RI value, the first PMI and the second PMI are orthogonal, and the first CQI and the second CQI are determined based on the same RI value.

A1 to A5 may be any integer.

To sum up, in the embodiment of the present application, the network device may notify the terminal device of the association between the first resource configuration and the second resource configuration and the association manner indicated by the first indication information through the various embodiments described above; when the terminal device determines the first channel state information and the second channel state information, each channel state information may satisfy one or more of the following information: the first RI and the second RI are the same, the first PMI and the second PMI are determined based on the same RI value, the first PMI and the second PMI are orthogonal, the first CQI and the second CQI are determined based on the same RI value, and the first SINR and the second SINR are determined based on the same RI value. Therefore, in the embodiment of the present application, the terminal device may report the same RI that both resources in the two resource configurations can support, so as to effectively support that two beams corresponding to the two resource configurations transmit the same data stream, without affecting transmission performance. In addition, each channel state information simultaneously satisfies one or more information, and the transmission performance can be further improved when the same data is transmitted by multiple beams simultaneously.

That is to say, compared with the prior art in which the network device directly limits the terminal device to report the specific RI without knowing the RI that can be supported by the resource in each resource configuration, in the embodiment of the present application, the terminal device may determine a uniform RI after respectively measuring the RI that can be supported by the resource in each resource configuration based on the association relationship of the resource configurations, thereby comprehensively considering the capability of each channel, and avoiding the problems of channel waste capability or low transmission reliability caused by blindly limiting the specific RI. In addition, the embodiment of the application can report the corresponding PMI, CQI, SINR and the like in combination with the same RI, thereby further improving the reliability of transmission.

In addition, in the second measurement configuration information sent by the network device to the terminal device, the second resource configuration may also have the first identifier, the association relation field, the first indication information, and the like described in the above various embodiments, so that the terminal device determines another resource configuration associated with the second resource configuration identified by the second identifier, such as the first resource configuration identified by the first identifier; and determining channel state information for each associated resource configuration. That is, the second resource configuration may or may not include the first identifier, the association relation field, the first indication information, and the like. For example, as shown in fig. 4d, compared with fig. 4c, the second resource configuration ResourceConfig2 includes a second identifier and an association relationship field associationrelationship, and the association relationship field includes a first identifier idourceconfig 1 and first indication information AssociationPattern1. That is, when the second resource configuration includes other identifiers, such as the first identifier, besides the second identifier of the terminal device, the terminal device may determine the resource configuration associated with the second resource configuration, such as the first resource configuration, based on the other identifiers, such as the first identifier. When the second resource configuration does not include other identifiers except the second identifier of the terminal device, the terminal device may determine that the first resource configuration is associated with the second resource configuration according to the second identifier in the first resource configuration because the first resource configuration includes the second identifier.

It should be understood that the above description describes a related case where the first resource configuration is associated with the second resource configuration, and the embodiments of the present application can also be adapted to a case where the first resource configuration is associated with a plurality of resource configurations, resource sets and/or resources, so as to effectively support multiple beams transmitting the same data. For example, the first resource allocation may further include a plurality of other identifiers similar to the second identifier, and each resource allocation, resource set, or resource identified by the other identifiers is respectively associated with the first resource allocation; and each resource configuration, resource set or resource identified by the other identifier also has a corresponding reporting configuration, which is used for reporting the respective channel state information. As another example, a plurality of other identifiers similar to the second identifier may be located in the association field of the first resource configuration. Accordingly, the embodiments of the terminal device determining the channel state information corresponding to each of the plurality of associated resource configurations, resource sets, and/or resources are also the same as the above embodiments. Therefore, although the first identifier and the second identifier are mainly described herein, the embodiments described herein are also applicable to a case where more than two resource configurations, resource sets or resource associations are provided, and in particular, they are not described in detail herein.

1.2, the first identifier is used for indicating a first resource set; the second identification is used for indicating a second resource set; the first resource set is associated with the second resource set;

this embodiment differs from the embodiment described in 1.1 in that the first identity and the second identity are identified at different levels, e.g. the first identity and the second identity are identities of resource sets, not identities of resource configurations. And, the first resource set identified by the first identifier and the second resource set identified by the second identifier are respectively located in different resource configurations, for example, the first resource configuration includes the first resource set, and the second resource configuration includes the second resource set. The first channel state information is determined according to the first set of resources and reported according to the first measurement configuration information or the first reporting configuration. The second channel state information is determined according to the second set of resources and reported according to the second measurement configuration information or the second reporting configuration.

Similarly, the way in which the network device notifies the terminal device of the association relationship between the first resource set and the second resource set is similar to the embodiment described in 1.1 above, except that in 1.2, the first identifier and the second identifier are located in the first resource set in the first resource configuration, and in 1.2, the association relationship field is included in the first resource set. In this way, the terminal device may determine the resource set associated with the first resource set based on the identity contained in the first resource set.

For example, in this embodiment, the way for the network device to notify the terminal device of the association relationship between the first resource set and the second resource set by using the first resource configuration may be: as shown in fig. 5a, the first resource configuration ResourceConfig1 includes a first resource set ResourceSet1, and the second resource configuration ResourceConfig2 includes a second resource set ResourceSet2; and the first resource set includes a first identifier and a second identifier in resource set1, where the first identifier idoffresourceset 1 is an identifier of the first resource set, and the second identifier idoffresourceset 2 is an identifier of the second resource set, so that the terminal device determines the second resource set associated with the first resource set according to the identifier included in the first resource set. Special association fields may also be employed to inform the association between resource sets. As shown in fig. 5b, compared with fig. 5a, the first resource set1 includes a first identity idoffourceset 1 and an association relationship field associationrelationship, which includes a second identity idoffourceset 2; thus, the terminal device may determine the second resource set associated with the first resource set according to the second identifier included in the associationrelationship.

Similarly, after determining that the first resource set is associated with the second resource set, the terminal device may further determine an association manner of the first channel state information and the second channel state information. For example, besides the RI in the first channel state information and the RI in the second channel state information are the same, other parameters in the first channel state information and the second channel state information may also have corresponding association manners. For example, a first PMI, a first CQI and/or a first SINR in the first channel state information and a second PMI, a second CQI and/or a second SINR in the second channel state information have a corresponding association. Optionally, the first channel state information and the second channel state information satisfy at least one of the following association modes: the first RI and the second RI are the same, the first PMI and the second PMI are determined based on the same RI value, the first PMI and the second PMI are orthogonal, the first CQI and the second CQI are determined based on the same RI value, and the first SINR and the second SINR are determined based on the same RI value.

Specifically, the embodiment in which the terminal device determines the association manners may be described with reference to 1.1, and is different from 1.1 in that 1.1 is the first channel state information and the second channel state information determined for the first resource configuration and the second resource configuration, and the embodiment is the first channel state information and the second channel state information determined for the first resource set and the second resource set.

Similarly, as in 1.1 above, the terminal device may further determine, according to the first indication information, an association manner between the first channel state information and the second channel state information. For example, as shown in fig. 5c, compared with fig. 5b, the association relation field association relationship further includes first indication information association pattern1, where the association pattern1 is used to indicate the association manner of the first channel state information and the second channel state information, so that the terminal device determines the second resource set associated with the first resource set according to the idoffourceset 2 and the association pattern1 in the association relationship of the first resource set ResourceSet 1.

According to the embodiment of the application, the RI reported by the measurement of the associated resource sets is the same through the associated resource sets, so that the multi-beam transmission of the same data is effectively supported. In addition, other parameters simultaneously satisfy one or more constraint relations, and the transmission performance can be further improved while the multi-beam simultaneously transmits the same data.

That is to say, compared with the prior art in which the network device directly limits the terminal device to report a specific RI without knowing the RI that can be supported by the resource in each resource set, the terminal device may determine a uniform RI after measuring the RI that can be supported by the resource in each resource set based on the association of the resource sets, thereby comprehensively considering the capability of each channel and avoiding the problems of channel waste capability or low transmission reliability caused by blindly limiting the specific RI. In addition, the embodiment of the present application may also report the corresponding PMI, CQI, SINR, and the like in combination with the same RI, thereby further improving the reliability of transmission.

Similarly, as described in the above 1.1, in the second measurement configuration information sent by the network device to the terminal device, the second resource set may also have the first identifier, the association relation field, the first indication information, and the like described in the foregoing various embodiments, so that the terminal device determines another resource set associated with the second resource set identified by the second identifier, such as the first resource set identified by the first identifier; and determining channel state information for each associated set of resources. That is, the second resource configuration may or may not include the first identifier, the association relation field, the first indication information, and the like described above; when the second resource configuration includes other identifiers, such as the first identifier, besides the second identifier, the terminal device may determine, based on the other identifiers, such as the first identifier, a resource set associated with the second resource set, such as the first resource set; when the second resource configuration does not include other identifiers except the second identifier, the terminal device can still determine that the first resource set is associated with the second resource set according to the first resource set because the first identifier and the second identifier are included in the first resource set. Optionally, the second resource set association relationship field may also include the first identifier and the first indication information, where the first indication information is used to indicate an association manner of channel state information between associated resource sets, for example, as shown in fig. 5d, compared with fig. 5c, the second resource set2 further includes an association relationship field association relationship, and the association relationship field includes the first identifier idoffourceset 1 and the first indication information association pattern1.

It should be understood that the above description describes a related case where a first resource set is associated with a second resource set, and the embodiments of the present application can also be adapted to a case where the first resource set is associated with a plurality of resource sets, resource configurations, and/or resources. For example, the first resource set may further include other identifiers similar to the second identifier, and the resource sets, resource configurations, and/or resources identified by the other identifiers are also associated with the first resource set identified by the first identifier; and the resource configuration identified by the other identifier or the resource configuration to which the identified resource set and/or resource respectively belong also has corresponding reporting configuration for reporting the respective channel state information. For another example, a plurality of other identifiers similar to the second identifier may be located in the association relationship field of the first resource set; accordingly, the embodiments of the terminal device for determining the associated resource sets, resource configurations and/or channel state information corresponding to the resources are also the same as the embodiments described above. Thus, although the first and second identifiers are primarily discussed herein, the same is true for a plurality of similar second identifiers.

1.3, the first identifier is used for indicating a first resource; the second identification is used for indicating a second resource; associating a first resource with a second resource

This embodiment differs from the embodiments described in 1.1 and 1.2 in that the first identifier and the second identifier are identified at different levels, i.e. the first identifier and the second identifier are identifiers of resources. The first resource and the second resource are respectively located in different resource configurations, for example, the first resource configuration includes the first resource, and the second resource configuration includes the second resource. Therefore, in step 102, the first csi is determined according to the first resource and reported according to the first measurement configuration information or the first reporting configuration. Similarly, the second channel state information is determined according to the second resource and reported according to the second measurement configuration information or the second reporting configuration.

Similarly, the way in which the network device notifies the terminal device of the association relationship between the first resource and the second resource is similar to the embodiment described in 1.1 above, except that the first identifier and the second identifier are located in the first resource in 1.3, and the association relationship field in 1.3 is included in the first resource. In this way, the terminal device may determine the second resource associated with the first resource according to the identifier and/or association relation field contained in the first resource.

For example, as shown in fig. 6a, the first Resource1 includes the first identifier idoffresource 1 and the second identifier idoffresource 2, where the first identifier idoffresource 1 is an identifier of the first Resource itself, and the second identifier idoffresource 2 is an identifier of the second Resource; in this way, the terminal device may determine the second resource associated with the first resource according to the second identifier included in the first resource. As shown in fig. 6b, the first Resource1 includes a first identifier idoffresource 1 and an association relation field association relation, which includes a second identifier idoffresource 2, that is, the difference from fig. 6a is that the second identifier is located in the association relation field of the first Resource, so that the terminal device can determine the second Resource associated with the first Resource according to the second identifier included in the association relation.

Similarly, the terminal device determines that the first resource is associated with the second resource based on the various embodiments described above, and may also determine an association manner of the first channel state information and the second channel state information. For example, besides the same RI in the first channel state information and the second channel state information, there may be a corresponding association manner in other parameters in the first channel state information and the second channel state information. For example, a first PMI, a first CQI, and/or a first SINR in the first channel state information may be associated with a second PMI, a second CQI, and/or a second SINR in the second channel state information. Optionally, the first channel state information and the second channel state information satisfy one or more of the following association modes: the first RI and the second RI are the same, the first PMI and the second PMI are determined based on the same RI value, the first PMI and the second PMI are orthogonal, the first CQI and the second CQI are determined based on the same RI value, and the first SINR and the second SINR are determined based on the same RI value. Specifically, the embodiment in which the terminal device determines the association manners is similar to the embodiment described in 1.1, except that 1.1 is the first channel state information and the second channel state information determined for the first resource configuration and the second resource configuration, and the embodiment is the first channel state information and the second channel state information determined for the first resource and the second resource.

Similarly, as in 1.1 above, the terminal device may further determine, according to the first indication information, an association manner between the first channel state information and the second channel state information. As shown in fig. 6c, the difference from fig. 6b is that the associationrelationship further includes first indication information AssociationPattern1; in this way, the terminal device can specify the second resource and the association method associated with the first resource based on the second identifier and the first instruction information included in the association relationship.

According to the embodiment of the application, the RI reported by the associated resource measurement is the same through the associated resources, so that the multi-beam transmission of the same data is effectively supported. In addition, other parameters simultaneously satisfy one or more constraint relations, and the transmission performance can be further improved while the multi-beam simultaneously transmits the same data.

Compared with the prior art, the network equipment directly limits the terminal equipment to report the specific RI under the condition that the RI which can be supported by each resource is unknown, the terminal equipment can respectively measure the RI which can be supported by each resource based on the resource association and then determine a uniform RI, thereby comprehensively considering the capacity of each channel and avoiding the problems of channel waste capacity or low transmission reliability and the like caused by blindly limiting the specific RI. In addition, the embodiment of the present application may report the corresponding PMI, CQI, SINR, and the like in combination with the same RI, thereby further improving the reliability of transmission.

Similarly, as described in the above 1.1, in the second measurement configuration information sent by the network device to the terminal device, the second resource may also have the first identifier, the association relation field, the first indication information, and the like described in the above various embodiments, so that the terminal device determines other resources associated with the second resource identified by the second identifier, such as the first resource identified by the first identifier, and determines channel state information of each associated resource. That is, the second resource may or may not include the first identifier, the association relation field, the first indication information, and the like described above; when the second resource includes other identifiers, such as the first identifier, besides the second identifier, the terminal device may determine, based on the other identifiers, such as the first identifier, a resource associated with the second resource, such as the first resource; when the second resource does not include any identifier other than the second identifier, the terminal device can still determine that the first resource is associated with the second resource according to the first resource because the first resource includes the first identifier and the second identifier. Optionally, the second Resource may include an association relation field, and the association relation field may include a first identifier and first indication information, where the first indication information is used to indicate an association manner of channel state information between associated resources, for example, as shown in fig. 6d, compared with fig. 6c, the second Resource2 further includes its own identifier, that is, a second identifier, and an association relation field association relationship, and the association relation field includes a first identifier IDofResource1 and first indication information association pattern1.

It should be understood that the above description explains the relevant case of associating the first resource with the second resource, and the embodiments of the present application can also be adapted to the case of associating the first resource with a plurality of resources. For example, the first resource may further include other identifiers similar to the second identifier, and the resources identified by the other identifiers are also associated with the first resource identified by the first identifier; and the resource configuration to which the resource identified by the other identifier respectively belongs also has a corresponding reporting configuration, and is used for reporting the respective channel state information. For another example, the identifier included in the first resource may include other identifiers in addition to the second identifier, and the processing method for the resource identified by the other identifiers is the same as the second identifier. For another example, more other identifiers similar to the second identifier may be located in the association field of the first resource. Accordingly, the embodiments in which the terminal device identifies the channel state information corresponding to each resource associated with the terminal device are also the same as the above embodiments. Therefore, although the first identifier and the second identifier are mainly described herein, the same applies to a plurality of similar second identifiers.

1.4, the first identifier is used for indicating a first resource set; the second identification is used for indicating a second resource; associating the first resource set with the second resource

This embodiment differs from the embodiment described in 1.1 in that the first identity and the second identity are identified at different levels, i.e. the first identity is an identity of a set of resources and the second identity is an identity of a resource. The first resource set and the second resource are respectively located in different resource configurations, for example, the first resource configuration includes the first resource set, the second resource configuration includes the second resource set, and the second resource set includes the second resource. In step 102, the first channel state information is determined according to the first resource set and reported according to the first measurement configuration information or the first reporting configuration. The second channel state information is determined according to the second resource and reported according to the second measurement configuration information or the second reporting configuration.

Similarly, the way in which the network device notifies the terminal device of the association relationship between the first resource set and the second resource may also be similar to the implementation manner described in 1.1 above, except that in 1.4, the first identifier and the second identifier are located in the first resource set, and the association relationship field in 1.4 is included in the first resource set. In this way, the terminal device may determine a resource set, a resource or a resource configuration, etc. associated with the first resource set according to the identifier and/or the association relation field included in the first resource set.

For example, as shown in fig. 7a, a first resource set ResourceSet1 includes the first identifier IDofResourceSet1 and a second identifier IDofResource2, the first identifier is an identifier of the first resource set itself, and the second identifier is an identifier of the second resource, so that the terminal device may determine the associated resource or/and resource set according to the identifier included in the first resource set. As shown in fig. 7b, the difference from fig. 7a is that the first resource set1 further includes an association relation field association relation, and the second identifier is located in the association relation field, that is, the association relation field association relation includes the second identifier IDofResource2, so that the terminal device determines the resource, the resource configuration, or the resource set associated with the first resource set according to the identifier included in the association relation field association relation.

Similarly, the terminal device determines that the first resource set is associated with the second resource based on the various embodiments described above, and may also determine an association manner of the first channel state information and the second channel state information. Besides the RI in the first channel state information and the RI in the second channel state information are the same, other parameters in the first channel state information and the second channel state information may also have corresponding association manners. For example, a first PMI, a first CQI, and/or a first SINR in the first channel state information may be associated with a second PMI, a second CQI, and/or a second SINR in the second channel state information. Optionally, parameters in the first channel state information and the second channel state information satisfy one or more of the following association modes: the first RI and the second RI are the same, the first PMI and the second PMI are determined based on the same RI value, the first PMI and the second PMI are orthogonal, the first CQI and the second CQI are determined based on the same RI value, and the first SINR and the second SINR are determined based on the same RI value. Specifically, the terminal device determines the above-mentioned association manners in an embodiment, which may be described with reference to 1.1 above, and differs from 1.1 in that 1.1 is first channel state information and second channel state information determined for a first resource configuration and a second resource configuration, where in this embodiment, the first channel state information is determined for a first resource set and the second channel state information is determined for a second resource.

Similarly, as in 1.1 above, the terminal device may further determine, according to the first indication information, an association manner between the first channel state information and the second channel state information. As shown in fig. 7c, compared with fig. 7b, the association relation field association relationship further includes first indication information association pattern, where the association pattern is used to indicate the association manner of the first channel state information and the second channel state information, so that the terminal device determines the resource, the resource set or the resource configuration associated with the first resource set and the association manner according to the association relationship in the resource set 1.

Therefore, the embodiment of the present application may not only report the same RI that both the first resource set and the second resource can support, thereby facilitating that when two beams corresponding to the first resource set and the second resource respectively transmit the same data stream, the transmission performance is not affected. In addition, other parameters simultaneously satisfy one or more constraint relations, so that the transmission performance can be further improved while the multi-beam simultaneously transmits the same data. Similarly, in the embodiment of the present application, based on the association between the first resource set and the second resource, the terminal device may measure the RIs that can be supported by the first resource set and the second resource, respectively, and then determine a uniform RI after the RI that can be supported by the second resource is measured, so as to comprehensively consider the capabilities of each channel, and avoid the problems of channel waste capability or low transmission reliability caused by blindly limiting a specific RI. In addition, the embodiment of the application can report the corresponding PMI, CQI, SINR and the like in combination with the same RI, thereby further improving the reliability of transmission.

In addition, similarly, as described in the above 1.1, in the second measurement configuration information sent by the network device to the terminal device, the second resource may also have the first identifier, the association relation field, the first indication information, and the like described in the foregoing various embodiments, so that the terminal device determines another resource set associated with the second resource identified by the second identifier, for example, the first resource set identified by the first identifier, and determines the channel state information of the associated resource set and the resource. That is, the second resource may or may not include the first identifier, the association relation field, the first indication information, and the like. For example, when the second resource includes other identifiers, such as the first identifier, besides the second identifier of the terminal device itself, the terminal device may determine a resource set, such as the first resource set, associated with the second resource based on the other identifiers, such as the first identifier; when the second resource does not include other identifiers except the second identifier of the terminal device, the terminal device can still determine that the first resource set is associated with the second resource according to the first resource set because the first resource set includes the first identifier and the second identifier. Optionally, the second Resource may also include a second identifier of the second Resource and an association relation field, where the association relation field may include a first identifier and first indication information, and the first indication information is used to indicate an association manner of channel state information between the associated Resource set and the Resource, for example, as shown in fig. 7d, compared with fig. 7c, the second Resource2 further includes an association relation field association relationship, and the association relation field includes the first identifier IDofResourceSet1 and the first indication information association pattern1.

It should be understood that the above description describes a related case where a first resource set is associated with a second resource, and the embodiments of the present application can also be adapted to a case where the first resource set is associated with a plurality of resources, resource configurations, and/or resource sets. For example, the first resource set may further include other identifiers similar to the second identifier, and the resources, resource configurations, and/or resource sets identified by the other identifiers are also associated with the first resource set identified by the first identifier; and the resource allocation identified by the other identifier and/or the resource allocation to which the identified resource and/or resource set respectively belongs have corresponding reporting configurations, so as to report the corresponding channel state information. As another example, more other identifiers similar to the second identifier may be located in the association relationship field of the first set of resources. Therefore, the first identifier and the second identifier are mainly described herein, but the embodiments described herein are also applicable to more than two resource configurations, resource sets, and resource associations, and are not described in detail herein.

It can be seen that, 1.4, the first identifier is an identifier of a resource set, the second identifier is an identifier of a resource, and the resource set and the resource can be associated with each other; 1.1-1.3 above all refer to the same level of association, for example, the first resource configuration is associated with the second resource configuration, the first resource set is associated with the second resource set, and the first resource is associated with the second resource. Therefore, in the embodiment of the present application, association between different levels is also possible, and a configuration manner or a notification manner of the association, and a manner how the terminal device determines the corresponding channel state information are also similar to those described in above 1.1-1.4, and are not described in detail here. In addition, the number of the associated resources, resource sets, or resource configurations may also be multiple, and the terminal device may report the corresponding channel state information by using the reporting configuration corresponding to the resource configuration to which each resource, resource set belongs, or report the corresponding channel state information by using the reporting configuration corresponding to each resource configuration.

Referring to fig. 8, fig. 8 is a flowchart illustrating a method for acquiring channel state information according to another embodiment of the present application. The difference between the acquiring method described in fig. 8 and fig. 3a and 3b is that in the embodiment of the present application, one third channel state information may be reported for multiple associated resources or resource sets, and all the channel state information does not need to be reported for each resource or resource set, so that uplink resources can be saved. Specifically, the method for acquiring the channel state information shown in fig. 8 may include:

201. the network equipment sends third measurement configuration information to the terminal equipment; and the terminal equipment receives the third measurement configuration information sent by the network equipment.

Wherein the third measurement configuration information comprises: a third resource configuration and a third reporting configuration; the third resource configuration comprises a third identifier and a fourth identifier; the third identification is used for indicating a third resource set or a third resource; the fourth identification is used for indicating a fourth resource set or a fourth resource; the third set of resources or the third resource associated with the fourth set of resources or the fourth resource; the third resource configuration includes the third resource set and the fourth resource set, the third resource set includes the third resource, and the fourth resource set includes the fourth resource;

202. the terminal equipment determines third channel state information and sends the third channel state information according to the third measurement configuration information; and the network equipment receives the third channel state information sent by the terminal equipment.

The third channel state information is determined by the terminal device according to the third resource set or the third resource and the fourth resource set or the fourth resource, that is, in the embodiment of the present application, only one channel state information needs to be reported for a plurality of resource sets or resources, so that a problem of high resource overhead caused by reporting channel state information for each resource set or resource respectively is avoided. That is to say, the embodiment of the application can reduce the number of reported channel state information and save uplink resources.

In the following embodiment of the present application, the network device notifies the terminal device of a possible implementation manner of an association relationship between the third resource set or the third resource and the fourth resource set or the fourth resource, respectively; and the terminal device determines a possible implementation manner of the third channel state information according to the associated third resource set or third resource and the fourth resource set or fourth resource, and performs related explanation.

2.1, the third identifier is used for indicating a third resource set; the fourth identification is used for indicating a fourth resource set; the third set of resources is associated with the fourth set of resources;

in this embodiment, the third resource configuration includes a third resource set and a fourth resource set, the third channel state information is determined according to the third resource set and the fourth resource set, and the terminal device reports the third channel state information by using a third reporting configuration.

In the following, an alternative embodiment of how the network device associates the third resource set with the fourth resource set and notifies the terminal device of the association is described.

In an optional implementation manner, the manner in which the network device notifies the terminal device of the association relationship between the third resource set and the fourth resource set may be: the third resource set comprises the third identifier and a fourth identifier; optionally, the fourth resource set may also include the third identifier and the fourth identifier at the same time, and the terminal device may determine, according to the identifier included in the third resource set, a resource set associated with the third resource set, and/or determine, according to the identifier included in the fourth resource set, a resource set associated with the fourth resource set. For example, as shown in fig. 9a, the third resource set ResourceSet3 includes the third identifier idofresourcset 3 and the fourth identifier idofresourcset 4, and the third identifier idofresourcset 3 is an identifier of the third resource set, the terminal device may determine that the third resource set is associated with the fourth resource set. For another example, the fourth resource set resourcset 4 may also include a third identifier idoffourceset 3 and a fourth identifier idofforset 4, where the fourth identifier idoffourceset 4 is an identifier of the fourth resource set, and similarly, the terminal device may determine that the third resource set is associated with the fourth resource set.

In another optional implementation manner, the manner in which the network device notifies the terminal device of the association relationship between the third resource set and the fourth resource set may further be: at least one of the third resource set and the fourth resource set comprises an association relation field, and the association relation field comprises a non-self identification. For example, as shown in fig. 9b, the third resource set ResourceSet3 includes a third identifier idofforset 3 and an association field associationrequest, and the third identifier idoffset 3 is an identifier of the third resource set, and the associationrequest includes a fourth identifier idoffesoset 4, that is, an identifier of the fourth resource set. Thus, the terminal device may determine that the third set of resources is associated with the fourth set of resources. For another example, the fourth resource set ResourceSet4 contains a fourth identifier IDofResourceSet4 and an association relationship field association relationship, but the association relationship contains a third identifier IDofResourceSet3, so that the terminal device can determine that the third resource set is associated with the fourth resource set based on ResourceSet3 and/or ResourceSet 4.

In the following, how the terminal device determines the third channel state information when the terminal device associates the third resource set with the fourth resource set through the above-mentioned various optional embodiments is described.

In an optional implementation manner, the third channel state information includes a third CQI, where the third CQI is a CQI corresponding to the third resource set and the fourth resource set, that is, the terminal device determines the third CQI according to the third resource set and the fourth resource set. Optionally, the determining, by the terminal device, the third CQI according to the third resource set and the fourth resource set includes: the terminal equipment determines a seventh CQI and an eighth CQI, wherein the seventh CQI is a CQI obtained by independent measurement of the third resource set; the eighth CQI is a CQI independently measured by the fourth resource set; and the terminal equipment determines the third CQI according to the seventh CQI and the eighth CQI.

Wherein, the determining, by the terminal device, the third CQI according to the seventh CQI and the eighth CQI may be: the terminal device selects a maximum value, a minimum value, an average value, a value obtained by rounding up the average value, or a value obtained by rounding down the average value from the seventh CQI and the eighth CQI as a third CQI. Optionally, when the third CQI is a maximum value or a minimum value of the seventh CQI and the eighth CQI, the third channel state information further includes an identifier of a resource set corresponding to the maximum value or the minimum value.

In another optional implementation, the third channel state information includes a third SINR, where the third SINR is an SINR corresponding to the third resource set and the fourth resource set. That is, the terminal device determines the third SINR from the third set of resources and the fourth set of resources. Optionally, the determining, by the terminal device, the third SINR according to the third resource set and the fourth resource set includes: the terminal equipment determines a seventh SINR and an eighth SINR, wherein the seventh SINR is obtained by independent measurement of the third resource set; the eighth SINR is an SINR obtained by independent measurement of the fourth resource set; and the terminal equipment determines the third SINR according to the seventh SINR and the eighth SINR.

Wherein, the terminal device determines the third SINR according to the seventh SINR and the eighth SINR, and may be: the terminal device selects, as the third SINR, a maximum value, a minimum value, an average value, a value obtained by rounding up the average value, or a value obtained by rounding down the average value from among the seventh SINR and the eighth SINR. Optionally, when the third SINR is a maximum value or a minimum value of the seventh SINR and the eighth SINR, the third channel state information further includes an identifier of a resource set corresponding to the maximum value or the minimum value.

In another optional implementation manner, the third channel state information includes the third RSRP, and the third RSRP is an RSRP corresponding to the third resource set and the fourth resource set. That is, the terminal device determines the third RSRP from the third set of resources and the fourth set of resources. Optionally, the determining, by the terminal device, the third RSRP according to the third resource set and the fourth resource set includes: the terminal equipment determines a seventh RSRP and an eighth RSRP, wherein the seventh RSRP is the RSRP obtained by independent measurement of the third resource set; the eighth RSRP is an RSRP measured independently by the fourth resource set; and the terminal equipment determines the third RSRP according to the seventh RSRP and the eighth RSRP.

The determining, by the terminal device, the third RSRP according to the seventh RSRP and the eighth RSRP may be: and the terminal equipment selects a maximum value, a minimum value, an average value, a value obtained by rounding up the average value or a value obtained by rounding down the average value from the seventh RSRP and the eighth RSRP as a third RSRP. Optionally, when the third RSRP is a maximum value or a minimum value of the seventh RSRP and the eighth RSRP, the third channel state information further includes an identifier of a resource set corresponding to the maximum value or the minimum value.

In yet another alternative embodiment, the network device may also explicitly notify the terminal device of the association manner. For example, the third resource configuration further includes second indication information, where the second indication information is used to indicate one or more of the following information: a third CQI is a CQI corresponding to the third resource set and the fourth resource set, and the third channel state information includes the third CQI; a third SINR is SINRs corresponding to the third resource set and the fourth resource set, where the third channel state information includes the third SINR; and a third RSRP is an RSRP corresponding to the third resource set and the fourth resource set, and the third channel state information includes the third RSRP.

The second indication information may be located in a third resource set and a fourth resource set, or in an association relationship field of the third resource set and the fourth resource set. As shown in fig. 9c, compared with fig. 9b, the association relation field associationrelationship may further include second indication information AssociationPattern2, so that the terminal device may determine the associated resource set and the associated manner according to the association relation field. Similarly, the second indication information may also be a numerical value for indicating one or more of the above information.

For example, if the value of the second indication information is B1, the CQI association is indicated, and the third channel state information includes a unique third CQI, which is determined according to the third resource set and the fourth resource set; when the second indication information is a B2 value, the SINR association is represented, and the third channel state information comprises a unique third SINR and is determined according to a third resource set and a fourth resource set; when the second indication information is a B3 value, the RSRP association is represented, and the third channel state information comprises a unique third RSRP which is determined according to a third resource set and a fourth resource set; and when the second indication information is a B4 value, the CQI correlation and the SINR correlation are represented, and the third channel state information comprises a unique third CQI and a unique third SINR. Optionally, the second indication information may be further used to indicate that the third channel state information includes an identifier of the third resource set or the fourth resource set. Specifically, how the terminal device determines the one or more information according to the second indication information may refer to the relevant operation of the terminal device, and will not be described in detail here.

It should be understood that, the above description explains the relevant case of associating the third resource set with the fourth resource set, and the embodiments of the present application can also be adapted to the case of multiple resource sets and/or resource associations. For example, the identifier included in the third resource set may include, in addition to the fourth identifier, other identifiers, and the resource set or resource identified by the other identifiers is also associated with the third resource set. As another example, the other identifier may be located in an association field of a third set of resources. Accordingly, the embodiments of the terminal device for determining one piece of channel state information for each associated resource set and/or resource are also the same as the above embodiments, and are not described in detail here.

2.2 the third identifier is used for indicating a third resource, the fourth identifier is used for indicating a fourth resource, and the third resource is associated with the fourth resource;

the difference between this embodiment and the previous embodiment is that the third resource configuration includes a third resource and a fourth resource, the third channel state information is determined according to the third resource and the fourth resource, and the terminal device reports the third channel state information according to the third reporting configuration.

Similarly, the manner in which the network device notifies the terminal device of the association relationship between the third resource and the fourth resource may also be similar to the embodiment described in the above 2.1, except that the third resource set in the above 2.1 is modified into the third resource, and the fourth resource set is modified into the fourth resource. For example, the third resource includes an identifier of the fourth resource, and/or the fourth resource includes an identifier of the third resource. For another example, the third resource includes an association field, the association field includes an identifier of the fourth resource, and so on, which are not detailed here.

Similarly, when the terminal device determines that the third resource is associated with the fourth resource through the various optional embodiments described above, the terminal device may also refer to the embodiment in fig. 2.1, except that the third resource set in fig. 2.1 is modified into the third resource, and the fourth resource set is modified into the fourth resource. For example, a fourth CQI is a CQI corresponding to the third resource and the fourth resource, and the third channel state information includes the fourth CQI; a fourth SINR is an SINR corresponding to the third resource and the fourth resource, and the third channel state information includes the fourth SINR; and/or a fourth RSRP is an RSRP corresponding to the third resource and the fourth resource, and the third channel state information includes the fourth RSRP.

Similarly, the terminal device may also determine the third channel state information in an explicit manner. For example, the third measurement configuration information includes third indication information; the third indication information is used for indicating one or more of the following information: a fourth CQI is a CQI corresponding to the third resource and the fourth resource, and the third channel state information includes the fourth CQI; a fourth SINR is an SINR corresponding to the third resource and the fourth resource, and the third channel state information includes the fourth SINR; and a fourth RSRP is an RSRP corresponding to the third resource and the fourth resource, and the third channel state information includes the fourth RSRP. The third indication information may be located in the third resource and/or the fourth resource, or in an association relation field in the third resource and/or an association relation field in the fourth resource. Optionally, the third indication information may also be a numerical value used to indicate one or more of CQI association, SINR association, and RSRP association, and correspondingly, the third channel state information may include the fourth CQI, the fourth SINR, and/or the fourth RSRP.

It should be understood that the above description explains the relevant case of associating the third resource with the fourth resource, and the embodiment of the present application can also be adapted to the case of associating multiple resources. For example, the identifier included in the third resource may include, in addition to the fourth identifier, other identifiers, and the resource identified by the other identifiers is also associated with the third resource. As another example, the other identifier may be located in an association field of a third set of resources. Accordingly, the embodiments in which the terminal device determines one piece of channel state information for each associated resource are also the same as the embodiments described above, and detailed description thereof is omitted here.

Similarly, the above descriptions 2.1-2.2 all refer to the association between the same levels, for example, the third resource set is associated with the fourth resource set, and the third resource is associated with the fourth resource. Optionally, in this embodiment of the present application, different levels may also be associated with each other, and a configuration manner or a notification manner of the association relationship, and a manner of how the terminal device determines the corresponding channel state information are also similar to those described in the above 2.1 to 2.2, and are not described in detail here. In addition, the number of the associated resources and resource sets may also be multiple, and the terminal device may determine one channel state information for reporting multiple resources and/or resource sets, thereby saving signaling overhead.

Optionally, in 2.1 above, the fourth resource set or the fourth resource may include a third identifier and a fourth identifier, where the fourth identifier is an identifier of the fourth resource set or the fourth resource, and the third identifier is an identifier of a resource set or a resource associated with the fourth resource set or the fourth resource, for example, the identifier of the third resource set or the third resource, that is, the third identifier. Optionally, in 2.2, the fourth resource set or the fourth resource may include a fourth identifier and an association relation field, but the association relation field includes an identifier of the resource set or the resource associated with the fourth resource set or the fourth resource, such as a third identifier, so that the terminal device may determine the resource set or the resource associated with the fourth resource set or the fourth resource, such as the third resource set or the third resource, according to the association relation field in the fourth resource set or the fourth resource.

Optionally, the fourth resource set or the association relation field in the fourth resource may further include second indication information or third indication information, where the second indication information is used to indicate how to determine the channel state information of the associated resource set, and the third indication information is used to indicate how to determine the channel state information of the associated resource. For example, as shown in fig. 9d, compared with fig. 9c, the fourth resource set ResourceSet4 further includes an association relationship field associationrelationship, and the association relationship field includes a third identifier idovoreset 3 and second indication information AssociationPattern2.

Referring to fig. 10a, fig. 10a is a schematic flowchart illustrating a further method for acquiring channel state information according to an embodiment of the present application. Compared with the acquisition methods shown in fig. 3a and 3b, the acquisition method shown in fig. 10a is different in that the network device enables the terminal device to make each piece of channel state information satisfy a certain constraint relationship or association manner when reporting each piece of channel state information based on the associated reporting configuration through the associated reporting configuration. Specifically, as shown in fig. 10a, the method for acquiring channel state information may include:

301. the network equipment sends fourth measurement configuration information to the terminal equipment; the terminal device receives the fourth measurement configuration information.

The fourth measurement configuration information includes: a fourth resource configuration and a fourth reporting configuration. The fourth reporting configuration comprises a fifth identifier and a sixth identifier; the fifth identifier is used to indicate the fourth reporting configuration, that is, the fifth identifier is an identifier of the fourth reporting configuration; the sixth identifier is configured to indicate a fifth reporting configuration associated with the fourth reporting configuration, that is, the sixth identifier is an identifier of the fifth reporting configuration;

302. the terminal equipment sends fourth channel state information to the network equipment according to the fourth measurement configuration information; and the network equipment receives the fourth channel state information sent by the terminal equipment.

It can be seen that, in the method for acquiring channel state information shown in fig. 10a, the network device notifies the terminal device of the associated reporting configuration, which is beneficial for the terminal device to report the configuration based on the association, and each piece of reported channel state information may satisfy a certain constraint relationship or association manner.

Referring to fig. 10b again, compared with the method for acquiring channel state information shown in fig. 10a, in 301, the network device further sends fifth measurement configuration information to the terminal device; the terminal device also receives the fifth measurement configuration information. The fifth measurement configuration information includes a fifth resource configuration and a fifth reporting configuration. Correspondingly, in 302, the terminal device further sends fifth channel state information to the network device according to the fifth measurement configuration information; the network device also receives fifth channel state information sent by the terminal device.

Wherein the third RI and the fourth RI are the same; the fourth channel state information comprises the third RI; the fifth channel state information includes the fourth RI.

It can be seen that, in the method for acquiring channel state information shown in fig. 10b, through the associated reporting configurations, the RIs in the channel state information respectively reported by the associated reporting configurations are the same, so that the multi-beam transmission of the same data is effectively supported.

In the following embodiment of the present application, the network device notifies the terminal device of a possible implementation manner of association between the fifth reporting configuration and the sixth reporting configuration; and the terminal device determines possible implementation manners of the fourth channel state information and the fifth channel state information, and relevant explanations are made.

In an optional implementation manner, the manner in which the network device notifies the terminal device of the association relationship between the fourth reporting configuration and the fifth reporting configuration may be: the fourth reporting configuration comprises a fifth identifier and a sixth identifier, and/or the fifth reporting configuration comprises the fifth identifier and the sixth identifier, wherein the fifth identifier is an identifier of the fourth reporting configuration itself, and the sixth identifier is an identifier of the reporting configuration associated with the fourth reporting configuration, so that the terminal device determines the associated reporting configuration according to the identifier included in the fourth reporting configuration and/or the fifth reporting configuration. For example, as shown in fig. 11a, the fifth identifier idofportconfig 4 configures its own identifier for the fourth report, the sixth identifier idofportconfig 5 configures its own identifier for the fifth report, and the fourth report configuration ReportConfig4 includes the fifth identifier idofportconfig 4 and the sixth identifier idofportconfig 5. For another example, the fifth reporting configuration ReportConfig5 may also include a fifth identifier idoreportconfig 4 and a sixth identifier idoreportconfig 5. Thus, the terminal device may determine that the fourth reporting configuration is associated with the fifth reporting configuration.

In another optional implementation manner, the manner in which the network device notifies the terminal device of the association relationship between the fourth reporting configuration and the fifth reporting configuration may be: the fourth reporting configuration comprises a fifth identifier and an association relation field, and the association relation field comprises a sixth identifier; and/or, the fifth reporting configuration includes a sixth identifier and an association relation field, but the association relation field includes the fifth identifier. The fifth identifier is an identifier of the fourth reporting configuration, and the identifier in the association relationship field is an identifier of the reporting configuration associated with the fourth reporting configuration. And the terminal equipment determines the associated reporting configuration according to the association relation field included in the fourth reporting configuration and/or the fifth reporting configuration. For example, as shown in fig. 11b, compared with fig. 11a, the sixth flag included in the fourth reporting configuration is located in the association relation field, that is, the fourth reporting configuration ReportConfig4 includes the fifth flag id of ReportConfig4 and the association relation field association relationship, and the sixth flag is included in the association relation field. For another example, the fifth reporting configuration report 5 also includes a fifth identifier idofportconfig 5 and an association relation field associationrelationship, but the association relation field includes a fifth identifier idofportconfig 4. Thus, the terminal device may determine that the fourth reporting configuration is associated with the fifth reporting configuration.

How to determine the fourth channel state information and the fifth channel state information when the terminal device determines that the fourth reporting configuration is associated with the fifth reporting configuration is similar to the 1.1 related embodiment shown in fig. 3a and 3b, but the difference is that in the 1.1 related embodiment shown in fig. 3a and 3b, the first resource configuration is replaced by the fourth resource configuration, the second resource configuration is replaced by the fifth resource configuration, the first channel state information is replaced by the fourth channel state information, and the second channel state information is replaced by the fifth channel state information. In the following, a brief description is given of how to determine the fourth channel state information and the fifth channel state information, and other relevant contents may refer to the relevant contents described in section 1.1 in the embodiments shown in fig. 3a and fig. 3 b.

In an optional implementation manner, when the terminal device determines that the fourth reporting configuration is associated with the fifth reporting configuration, the terminal device may determine that the fourth channel state information and the fifth channel state information satisfy at least one of the following conditions: the third RI is the same as the fourth RI; a third PMI and a fourth PMI are determined based on the same RI value, the fourth channel state information including the third PMI; the fifth channel state information includes the fourth PMI; a third PMI and a fourth PMI are orthogonal, the fourth channel state information including the third PMI; the fifth channel state information includes the fourth PMI; a fifth CQI and a sixth CQI are determined based on the same RI value, the fourth channel state information including the fifth CQI; the fifth channel state information comprises the sixth CQI; a fifth SINR and a sixth SINR are determined based on the same RI value, the fourth channel state information including the fifth SINR; the fifth channel state information includes the sixth SINR.

In another optional implementation manner, when the terminal device determines that the fourth reporting configuration is associated with the fifth reporting configuration, an explicit manner may also be used to determine an association manner that needs to be satisfied by the fourth channel state information and the fifth channel state information. For example, the association relation field in the fourth reporting configuration includes fourth indication information, where the fourth indication information is used to indicate one or more of the following information: the third RI is the same as the fourth RI; a third PMI and a fourth PMI are determined based on a same RI value, the fourth channel state information including the third PMI; the fifth channel state information includes the fourth PMI; a third PMI and a fourth PMI are orthogonal, the fourth channel state information including the third PMI; the fifth channel state information includes the fourth PMI; a fifth CQI and a sixth CQI are determined based on the same RI value, and the fourth channel state information includes the fifth CQI; the fifth channel state information comprises the sixth CQI; a fifth SINR and a sixth SINR are determined based on the same RI value, the fourth channel state information including the fifth SINR; the fifth channel state information includes the sixth SINR. Optionally, the fourth indication information may also be a numerical value, different values of the fourth indication information may be used to indicate one or more of RI association, PMI association, CQI association, SINR association, and RSRP association, and correspondingly, the fourth channel state information and the fifth channel state may satisfy the one or more information. In particular, reference may be made to the related explanation of the above first indication information, which is not described in detail here.

For example, as shown in fig. 11c, compared with fig. 11b, the association relationship field association relationship further includes fourth indication information association pattern4, so that the terminal device can determine, according to the association relationship field, a fifth reporting configuration and a relationship mode associated with the fourth reporting configuration.

To sum up, in the embodiments of the present application, the network device may notify the terminal device of the association between the fourth reporting configuration and the fifth reporting configuration through the various embodiments, or further notify the terminal device of the association manner indicated by the fourth indication information; when the terminal device determines the fourth channel state information and the fifth channel state information, each channel state information may satisfy one or more of the following information: the third RI and the fourth RI are the same, the third PMI and the fourth PMI are determined based on the same RI value, the third PMI and the fourth PMI are orthogonal, the second CQI and the fourth CQI are determined based on the same RI value, and the third SINR and the fourth SINR are determined based on the same RI value. Therefore, in the embodiment of the present application, the terminal device may report the same RI that can be supported by both resources in the resource configuration associated with the two reporting configurations, so as to effectively support that the two beams corresponding to the two reporting configurations transmit the same data stream, without affecting transmission performance. In addition, each channel state information can satisfy one or more information, and when the same data is transmitted by multiple beams at the same time, the transmission performance can be further improved.

That is to say, compared with the prior art in which the network device directly limits the terminal device to report a specific RI without knowing the RI that can be supported by the resource in the resource configuration associated with each reporting configuration, in this embodiment of the present application, the terminal device may determine a uniform RI after respectively measuring the RI that can be supported by the resource in the resource configuration associated with each reporting configuration based on the association relationship of the reporting configuration, thereby comprehensively considering the capability of each channel, and avoiding the problems of channel waste capability or low transmission reliability caused by blindly limiting the specific RI. In addition, the embodiment of the application can report the corresponding PMI, CQI, SINR and the like in combination with the same RI, thereby further improving the reliability of transmission.

In addition, the fifth reporting configuration may also have the fifth identifier, the association relation field, the fourth indication information, and the like described in the foregoing various embodiments, so that the terminal device determines another reporting configuration associated with the fifth reporting configuration, for example, the fourth reporting configuration identified by the fifth identifier; and determining channel state information of each associated reporting configuration, such as channel state information corresponding to the associated fourth reporting configuration and the associated fifth reporting configuration, respectively. That is, the fifth reporting configuration may or may not include the fifth identifier, the association relation field, the fourth indication information, and the like. For example, when the fifth reporting configuration includes other identifiers, such as the fifth identifier, besides the sixth identifier of the terminal device, the terminal device may determine, based on the other identifiers, such as the fifth identifier, the reporting configuration associated with the fifth reporting configuration, such as the fourth reporting configuration. When the fifth reporting configuration does not include other identifiers except the sixth identifier of the terminal device, because the fourth reporting configuration already includes the sixth identifier or also includes the first indication information, the terminal device may determine, according to these pieces of information of the fourth reporting configuration, that the fourth reporting configuration is associated with the fifth reporting configuration.

Optionally, the fifth reporting configuration may include a sixth identifier and an association relation field of the fifth reporting configuration, where the association relation field includes an identifier of the reporting configuration associated with the fifth reporting configuration, such as the fifth identifier, and fourth indication information, and thus, the terminal device may determine, based on the association relation field, the reporting configuration associated with the fifth reporting configuration and channel state information respectively corresponding to the associated reporting configuration. For example, as shown in fig. 11d, compared with fig. 11c, the fifth reporting configuration ReportConfig5 includes a sixth identifier idoreportconfig 5 and an association relation field associationrelationship, and the association relation field includes a fifth identifier idoreportconfig 4 and a fourth indication information AssociationPattern4.

It should be understood that, the above description explains a relevant case of associating the fourth reporting configuration with the fifth reporting configuration, and the embodiments of the present application can also be adapted to a case of associating multiple reporting configurations, so that multiple beams can be effectively supported to transmit the same data. For example, the fourth reporting configuration may further include a plurality of other identifiers similar to the sixth identifier, and each reporting configuration identified by the other identifiers is associated with the fourth reporting configuration, respectively; and each reporting configuration identified by the other identifier is used for reporting the respective channel state information. For another example, the plurality of other identifiers similar to the sixth identifier may be located in the association relation field of the fourth reporting configuration. Accordingly, the embodiments in which the terminal device determines the channel state information corresponding to each of the multiple associated reporting configurations are also the same as the above embodiments. Therefore, although the fifth identifier and the sixth identifier are mainly described herein, the embodiments described herein are also applicable to the case of associating more than two reporting configurations, and in particular, they are not described in detail herein.
