Description
Technical Field
The present invention relates to the field of wireless communication technologies, and in particular, to a method and an apparatus for interference measurement.
Background
In a dynamic TDD (Time Division duplex) system, if a base station side acquires CLI (Cross Link Interference) information between terminals, it can be helpful for operations such as dynamic resource allocation and cooperative scheduling, thereby improving system performance. Currently, in the prior art, two methods are mainly provided for CLI measurement reporting between UE and UE (user and user): the method is based on a measurement reporting mode of SRS-RSRP (SRS Reference Signal Receiving Power) and RSSI (Received Signal Strength Indicator). Wherein, RSRP refers to a linear average value of received signal power on all REs (resource elements) carrying reference signals; RSSI is the linear average of the power of all signals (including reference and data signals, adjacent interference signals, noise signals, etc.) received in Symbol, and is the received signal strength indicator.
Interference measurement reporting based on SRS-RSRP requires configuring a specific Reference signal for an interferer UE, for example, by configuring SRS (Sounding Reference signal) for interference measurement.
However, according to the existing 5G NR (New Radio, New air interface) standard, in the prior art, RSSI is usually calculated by RSRP, RSRQ (Reference Signal Received Quality) is calculated by further combining RSRP, and then reported by layer 1, and RSRP or RSRQ is mainly reported when layer 1 reports. But the RSSI may contain both co-cell interference and different-cell interference. For interference management of dynamic TDD, cross-link interference between users expected to be reached is relatively high.
In summary, no scheme for measuring cross link interference between users exists in the prior art.

Detailed Description
In the communication process, interference information often exists, so that the communication quality of a communication channel between a base station and a terminal is reduced, even communication cannot be performed, and if the base station side acquires the cross link interference information between the terminals, the base station side can contribute to operations such as dynamic resource allocation and cooperative scheduling, so that the system performance is improved.
In the prior art, two modes are mainly provided for CLI measurement reporting between UE and UE: and a measurement reporting mode based on SRS-RSRP and RSSI. RSRP refers to the linear average of the received signal power over all REs carrying reference signals; RSSI is the linear average of the power of all signals (including reference and data signals, adjacent interference signals, noise signals, etc.) received in Symbol, and is the received signal strength indicator.
Interference measurement reporting based on SRS-RSRP requires configuring a specific Reference signal for an interferer UE, for example, by configuring SRS (Sounding Reference signal) for interference measurement.
However, according to the existing 5G NR (New Radio, New air interface) standard, in the prior art, RSSI is usually calculated by RSRP, RSRQ (Reference Signal Received Quality) is calculated by further combining RSRP, and then reported by layer 1, and RSRP or RSRQ is mainly reported when layer 1 reports. But the RSSI may contain both co-cell interference and different-cell interference. For interference management of dynamic TDD, cross-link interference between users expected to be reached is relatively high.
The embodiment of the invention provides an interference measurement method and device, relates to network side equipment for configuring interference measurement resources for a terminal and the terminal for performing interference measurement, and can realize inter-user CLI measurement when the uplink and downlink transmission directions between a service cell of the terminal and an adjacent cell are inconsistent.
In the embodiment of the invention, the RSSI is redefined. Wherein, the L1-RSSI comprises a linear average value of the power of all signals (including reference signals and data signals, adjacent cell interference signals, noise signals and the like) received by all REs carrying the ZP CSI-RS; alternatively, the L1-RSSI comprises a linear average of the power of all signals (including reference signals and data signals, neighbor interference signals, noise signals, etc.) received on all REs carrying Ratematch patterns.
Some of the words that appear in the text are explained below:
(1) in the embodiments of the present application, the term "plurality" means two or more, and other terms are similar thereto.
(2) "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.
(3) In the embodiment of the application, "ZP CSI-RS" is mainly used for rate matching in the prior art and can be reused as interference measurement in the invention.
(4) In the embodiment of the present application, "Ratematch Pattern" is mainly used for rate matching in the prior art, that is, a user is in an idle state on a resource receiving the Ratematch, and can be reused as interference measurement in the present invention.
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, an embodiment of the present invention provides a method for interference measurement, where the method includes:
a terminal 100, configured to determine an interference measurement resource configured by a network side device, where the interference measurement resource is a resource carrying a zero power reference signal; the terminal carries out interference measurement on the interference measurement resource;
a network side device 101, configured to determine a zero-power reference signal resource that can be multiplexed as an interference measurement resource; and the network side equipment configures the interference measurement resource for the terminal so that the terminal performs interference measurement on the interference measurement resource.
In the method, the network side equipment determines the zero power reference signal resource which can be reused as the interference measurement resource, configures the interference measurement resource for the terminal, and then the terminal determines the interference measurement resource configured by the network side equipment and performs interference measurement on the interference measurement resource. Therefore, the network side device firstly determines the zero power reference signal resource which can be reused as the interference measurement resource, and then configures the specific zero power reference signal resource for interference measurement to the terminal, so that the terminal takes the received zero power reference signal resource which can be reused by the cell as the interference measurement resource, and performs interference measurement on the resource to obtain the interference measurement information. Therefore, when the uplink and downlink transmission directions between the service cell of the terminal and the adjacent cell are not consistent, the interference measurement of the terminal obtains the cross link interference between the terminal and the user of the adjacent cell, thereby obtaining the cross link interference between the users.
The zero power reference signal refers to that information sent by the base station of the local cell and received on the RE of the reference signal is zero, that is, on the current zero power reference signal resource, the behavior of the UE is in an idle state, and no measurement or any signal reception is performed.
Optionally, the zero-power reference signal includes, but is not limited to, a ZP CSI-RS and/or a Ratematch signal.
In particular implementations, the zero-power reference signals that can be multiplexed as interference measurement resources include, but are not limited to, ZP CSI-RS and/or Ratematch signals. The power of the cell signal received on the RE of the ZP CSI-RS and/or Ratematch signal is zero, that is, the RE of the ZP CSI-RS and/or Ratematch signal is in an idle state, so that after the network side device configures the ZP CSI-RS resource and/or Ratematch resource which can be reused as interference measurement resource to the terminal, if the uplink and downlink transmission directions between the serving cell of the terminal and the adjacent cell are not consistent, the cross link interference between the terminal and the user of the adjacent cell is obtained, thereby providing a scheme for measuring the cross link interference between users.
The two resources will be separately explained below.
Firstly, multiplexing the ZP CSI-RS resource as an interference measurement resource.
In specific implementation, the network side device determines a ZP CSI-RS resource that can be multiplexed as an interference measurement resource, where the interference measurement resource is a resource that carries part or all of the ZP CSI-RS resource.
Optionally, the network side device configures, for the terminal, a ZP CSI-RS resource that can be reused as an interference measurement resource in the ZP CSI-RS resources by configuring a parameter value used for indicating whether the ZP CSI-RS resource can be reused as an interference measurement.
Correspondingly, the terminal determines whether the corresponding ZP CSI-RS resource can be multiplexed as an interference measurement resource according to a parameter value used for indicating whether the ZP CSI-RS resource can be multiplexed as the interference measurement resource in the ZP CSI-RS resource configured by the network side equipment.
In the method, network side equipment configures ZP CSI-RS resources which can be multiplexed as interference measurement according to parameter values which are configured in high-level signaling and used for indicating whether the ZP CSI-RS resources can be multiplexed as interference measurement or not; correspondingly, the terminal determines whether the corresponding resource can be multiplexed as the interference measurement resource according to the parameter value which is configured by the received high-level signaling and used for indicating whether the resource can be multiplexed as the interference measurement resource. Therefore, the terminal can further select the ZP CSI-RS resource for interference measurement after determining the ZP CSI-RS resource which can be reused as the interference measurement resource, and finally realize the interference measurement on the ZP CSI-RS resource, so that the cross link interference between the terminal and the adjacent cell users is obtained.
For example: when a ZP CSI-RS resource is configured in a high-level signaling, introducing an enumeration type parameter 1 for indicating whether the ZP CSI-RS resource can be used for interference measurement or not, and when the value is on, indicating that the ZP CSI-RS resource can be used for interference measurement; and when the value is off, the ZP CSI-RS resource can not be used for interference measurement.
Further, after configuring and determining all ZP CSI-RS resources that can multiplex interference measurement resources, and before performing interference measurement, the network side device also configures interference measurement resources for performing interference measurement for the terminal, so that the terminal performs interference measurement on the interference measurement resources.
The manner in which the network side device continues to configure the interference measurement resource for the terminal is various, and will be described separately below.
And (I) the network side equipment configures interference measurement resources for the terminal through RRC signaling.
Optionally, the network side device configures an interference measurement period for the terminal through RRC signaling.
Correspondingly, the terminal performs interference measurement on the interference measurement resource configured by the network side equipment according to the interference measurement period configured by the network side equipment through the RRC signaling.
In specific implementation, the network side device configures an interference measurement period to the terminal through RRC signaling, and then the terminal receives the RRC signaling and then analyzes the RRC signaling to obtain the interference measurement period configured by the network side device, and performs periodic interference measurement on the configured ZP CSI-RS resource that can be reused as an interference measurement resource according to the obtained interference measurement period.
Wherein the interference measurement period is the same as the ZP-bearing CSI-RS resource period; or the interference measurement period is an integral multiple of the ZP-bearing CSI-RS resource period.
Therefore, the adaptive interference measurement period can be set according to the requirement in the specific implementation process.
Example 1: as shown in fig. 2, the network side device configures a periodic ZP CSI-RS resource with a period of 1slot, and the ZP CSI-RS resource can be multiplexed as an interference measurement resource, and if the interference measurement period is consistent with the ZP CSI-RS resource period, the terminal performs interference measurement on the ZP CSI-RS resource of each slot.
Example 2: as shown in fig. 3, the network side device configures a periodic ZP CSI-RS resource with a period of 1slot, and the ZP CSI-RS resource can be multiplexed as an interference measurement resource, and the interference measurement period is twice the period of the ZP CSI-RS resource, so that the terminal performs interference measurement on the ZP CSI-RS resource of the corresponding slot at intervals of one slot.
And (II) the network side equipment configures interference measurement resources for the terminal through MAC CE signaling.
Optionally, the network side device configures the number of times of measurement for the terminal through the MAC CE.
Correspondingly, the terminal performs interference measurement on the interference measurement resource configured by the network side equipment according to the measurement times configured by the network side equipment through the MAC CE.
In the method, the network side equipment configures the measurement times for the terminal through the MAC CE, and after receiving the MAC CE signaling configured with the measurement times, the terminal analyzes the configured measurement times and performs interference measurement on the determined interference measurement resource according to the configured measurement times.
Further, there is a delay from when the terminal receives the MAC CE signaling of the network side device to when the terminal responds to the MAC CE signaling to perform interference measurement.
Optionally, after receiving, in slot n, an activation measurement indication sent by the network side device through the MAC CE, the terminal is configured to send, in slot n, an activation measurement indication sent by the network side device through the MAC CEThen, interference measurement is carried out on the interference measurement resources;
Wherein, the corresponding time slot of the terminal is affected by the system parameter mu.
Example 3: as shown in fig. 4, the network side device activates the terminal to perform interference measurement on the ZP CSI-RS resource for 1 time through MAC-CE signaling, the UE receives the MAC-CE signaling in slot n, and then the terminal starts to perform interference measurement on the ZP CSI-RS resource for 1 time after slot n + 5.
Optionally, after configuring the interference measurement resource and the interference measurement times for the terminal through the MAC CE signaling, when the interference measurement times are 1, the interference measurement may be moved to the last timeslot for operation.
As shown in fig. 6, the network side device activates the terminal to perform interference measurement on the ZP CSI-RS resource for 1 time through the MAC-CE signaling, the UE receives the MAC-CE signaling in slot n, and then the terminal performs interference measurement on the last slot n +6 for one time.
And thirdly, after the ZP CSI-RS resource multiplexed as the interference measurement resource is configured for the terminal, the network side equipment sends an MAC-CE signaling to the terminal to indicate the terminal to carry out interference measurement on the configured ZP CSI-RS resource.
Optionally, the network side device sends an activation measurement instruction through the MAC CE, so that the terminal performs interference measurement on the configured interference measurement resource.
Correspondingly, the terminal performs interference measurement on the interference measurement resource configured by the network side device after receiving the activation measurement instruction sent by the network side device through the MAC CE.
In specific implementation, when the terminal receives an activation measurement instruction sent by the network side equipment through the MAC CE, the terminal prepares to perform interference measurement on the configured interference measurement resource, and continues to perform interference measurement on the ZP CSI-RS resource of each timeslot before receiving no other instruction sent by the network side equipment.
Further, when the terminal receives a signaling indicating to stop the interference measurement sent by the network side device, the interference measurement is stopped.
Optionally, the network side device sends a measurement deactivation instruction through the MAC CE, so that the terminal stops performing interference measurement on the configured interference measurement resource.
Correspondingly, after receiving the measurement deactivation instruction sent by the network side device through the MAC CE, the terminal stops performing interference measurement on the interference measurement resource configured by the network side device.
In specific implementation, by the method, the network side device can flexibly instruct the terminal to perform interference measurement when needed, and can instruct the terminal to stop the interference measurement, so that the interference measurement requirement can be met, the measurement times can be reduced to the maximum extent, and the energy loss of the terminal can be reduced.
For example: as shown in fig. 5, the network side device activates the terminal to perform interference measurement on the ZP CSI-RS resource through MAC-CE signaling, the UE receives an activation measurement instruction at slot n, and starts to perform interference measurement on the ZP CSI-RS resource reusable as an interference measurement resource at slot n + 5;
and the network side equipment sends a deactivation measurement instruction to the terminal through MAC-CE signaling, and after the terminal receives the deactivation measurement instruction at slot n +6, the terminal stops performing interference measurement on ZP CSI-RS resources of slot n + 9.
And (IV) after the ZP CSI-RS resource multiplexed as the interference measurement resource is configured for the terminal, the network side equipment sends DCI signaling to the terminal to indicate the terminal to carry out interference measurement on the configured ZP CSI-RS resource.
Optionally, if the network side device sends ZP CSI-RS resources on the multi-slot scheduled PDSCH and each slot includes ZP CSI-RS resources that can be multiplexed as interference measurement resources, the network side device instructs the terminal to perform interference measurement on the interference measurement resources of the last slot through DCI.
Correspondingly, if the terminal receives ZP CSI-RS resources sent by PDSCH scheduled by the network side equipment through DCI indication and each time slot contains ZP CSI-RS resources which can be multiplexed as interference measurement resources, the terminal carries out interference measurement on the interference measurement resources of the last time slot.
According to the method, when the network side equipment sends the ZP CSI-RS resource through the PDSCH which is scheduled by the multi-time slot, and each time slot contains the ZP CSI-RS resource which can be reused as the interference measurement resource, the interference measurement can be carried out only on the interference measurement resource of the last time slot, and therefore the power consumption of the terminal is effectively reduced.
As shown in fig. 6, the network side device triggers the terminal to perform interference measurement through DCI signaling, and after the terminal receives the measurement deactivation indication in slot n, the terminal performs interference measurement on the ZP CSI-RS resource of the last slot n + 6.
And secondly, multiplexing the Ratematch resource into an interference measurement resource.
In specific implementation, the network side device determines a Ratematch resource that can be multiplexed as an interference measurement resource, where the interference measurement resource is a part or all of a resource carrying the Ratematch resource.
Optionally, the network side device configures, for the terminal, a Ratematch resource that can be reused as an interference measurement resource in Ratematch resources by configuring a parameter value that is used to indicate whether the resource can be reused as the interference measurement in the Ratematch resources.
Correspondingly, the terminal determines whether the corresponding Ratematch resource can be multiplexed as the interference measurement resource according to a parameter value used for indicating whether the Ratematch resource can be multiplexed as the interference measurement in the Ratematch resource configured by the network side device.
In the method, the network side equipment configures the Ratematch resource which can be multiplexed as interference measurement according to the parameter value which is configured in the high-level signaling and used for indicating whether the parameter value can be multiplexed as interference measurement; correspondingly, the terminal determines whether the corresponding resource can be multiplexed as the interference measurement resource according to the parameter value which is configured by the received high-level signaling and used for indicating whether the resource can be multiplexed as the interference measurement resource. Therefore, the terminal can further select the Ratematch resource for performing interference measurement in determining the Ratematch resource which can be multiplexed as the interference measurement resource, and finally, the interference measurement is performed on the Ratematch resource, so that the cross link interference between the terminal and the adjacent cell is obtained.
For example: when the RateMatch pattern is configured in the high-level signaling, a new high-level parameter is introduced to indicate whether the RateMatch resource corresponding to the RateMatchPattern Id can be reused as interference measurement.
For example, enumeration type high-level parameter interference CLI-info is introduced, the value of the enumeration type high-level parameter interference CLI-info is { on, off }, and corresponding behaviors on the RateMatch resources are determined by judging the value of the received interference CLI-info at the UE end.
Namely, when the value of the interference CLI-info is on, the UE is indicated to carry out interference measurement on the RateMatch pattern; and when the value of the interference CLI-info is off, indicating that the UE performs Ratematch on the Ratematch pattern.
Further, after configuring and determining the Ratematch resources that can multiplex the interference measurement resources, the network side device also configures the interference measurement resources for performing interference measurement for the terminal before performing interference measurement, so that the terminal performs interference measurement on the interference measurement resources.
The manner in which the network side device continues to configure the interference measurement resource for the terminal is various, and will be described separately below.
And (I) the network side equipment configures interference measurement resources for the terminal through RRC signaling.
Optionally, the network side device configures an interference measurement period for the terminal through RRC signaling.
Correspondingly, the terminal performs interference measurement on the interference measurement resource configured by the network side equipment according to the interference measurement period configured by the network side equipment through the RRC signaling.
In specific implementation, the network side device configures an interference measurement period to the terminal through the RRC signaling, and then the terminal receives the RRC signaling and then analyzes the RRC signaling to obtain the interference measurement period configured by the network side device, and performs periodic interference measurement on the configured Ratematch resource that can be reused as the interference measurement resource according to the obtained interference measurement period.
Wherein the interference measurement period is the same as the Ratematch bearing resource period; or the interference measurement period is integral multiple of the Ratematch bearing resource period.
Therefore, the adaptive interference measurement period can be set according to the requirement in the specific implementation process.
Example 1: as shown in fig. 7, the network side device configures a periodic Ratematch resource with a period of 1slot, and the Ratematch resource may be multiplexed as an interference measurement resource, and if the interference measurement period is consistent with the period of the Ratematch resource, the terminal performs interference measurement on the Ratematch resource of each slot.
Example 2: as shown in fig. 8, the network side device configures a periodic Ratematch resource with a period of 1slot, and the Ratematch resource may be multiplexed as an interference measurement resource, and the interference measurement period is twice as long as the period of the Ratematch resource, so that the terminal performs interference measurement on the Ratematch resource of the corresponding slot every other slot.
And (II) the network side equipment configures interference measurement resources for the terminal through MAC CE signaling.
Optionally, the network side device configures the number of times of measurement for the terminal through the MAC CE.
Correspondingly, the terminal performs interference measurement on the interference measurement resource configured by the network side equipment according to the measurement times configured by the network side equipment through the MAC CE.
In the method, the network side equipment configures the measurement times for the terminal through the MAC CE, and after receiving the MAC CE signaling configured with the measurement times, the terminal analyzes the configured measurement times and performs interference measurement on the determined interference measurement resource according to the configured measurement times.
Further, there is a delay from when the terminal receives the MAC CE signaling of the network side device to when the terminal responds to the MAC CE signaling to perform interference measurement.
Optionally, after receiving, in slot n, an activation measurement indication sent by the network side device through the MAC CE, the terminal is configured to send, in slot n, an activation measurement indication sent by the network side device through the MAC CEThen, interference measurement is carried out on the interference measurement resources;
Wherein, the corresponding time slot of the terminal is affected by the system parameter mu.
Example 3: as shown in fig. 9, the network side device activates the terminal to perform interference measurement on the Ratematch resource 2 times through MAC-CE signaling, the UE receives the MAC-CE signaling in slot n, and then the terminal starts to perform interference measurement on the Ratematch resource 3 times after slot n + 5.
And thirdly, after configuring the Ratematch resource multiplexed as the interference measurement resource for the terminal, the network side equipment sends MAC-CE signaling to the terminal to indicate the terminal to perform interference measurement on the configured Ratematch resource.
Optionally, the network side device sends an activation measurement instruction through the MAC CE, so that the terminal performs interference measurement on the configured interference measurement resource.
Correspondingly, the terminal performs interference measurement on the interference measurement resource configured by the network side device after receiving the activation measurement instruction sent by the network side device through the MAC CE.
In specific implementation, when the terminal receives an activation measurement instruction sent by the network side device through the MAC CE, the terminal prepares to perform interference measurement on the configured interference measurement resource, and continues to perform interference measurement on the Ratematch resource of each timeslot until no other instruction sent by the network side device is received.
Further, when the terminal receives a signaling indicating to stop the interference measurement sent by the network side device, the interference measurement is stopped.
Optionally, the network side device sends a measurement deactivation instruction through the MAC CE, so that the terminal stops performing interference measurement on the configured interference measurement resource.
Correspondingly, after receiving the measurement deactivation instruction sent by the network side device through the MAC CE, the terminal stops performing interference measurement on the interference measurement resource configured by the network side device.
In specific implementation, by the method, the network side device can flexibly instruct the terminal to perform interference measurement when needed, and can instruct the terminal to stop the interference measurement, so that the interference measurement requirement can be met, the measurement times can be reduced to the maximum extent, and the energy loss of the terminal can be reduced.
For example: as shown in fig. 10, the network side device activates the terminal to perform interference measurement on the Ratematch resource through MAC-CE signaling, and the UE receives the activation measurement indication at slot 1 and starts interference measurement on the Ratematch resource at slot 5;
the network side equipment sends a measurement deactivation instruction to the terminal through MAC-CE signaling, and after the terminal receives the measurement deactivation instruction at slot 10, the terminal stops performing interference measurement on slot 14 and subsequent Ratematch resources.
And (IV) after configuring the Ratematch resource multiplexed as the interference measurement resource for the terminal, the network side equipment sends DCI signaling to the terminal to indicate the terminal to perform interference measurement on the configured Ratematch resource.
Optionally, if the network side device sends Ratematch resources on the multi-slot scheduled PDSCH and each slot includes a Ratematch resource that can be multiplexed as an interference measurement resource, the network side device instructs the terminal to perform interference measurement on the interference measurement resource of the last slot through the DCI.
Correspondingly, if the terminal receives the Ratematch resources sent by the PDSCH scheduled in the multi-slot by the network side device through the DCI indication, and each slot includes the Ratematch resources that can be multiplexed as interference measurement resources, the terminal performs interference measurement on the interference measurement resources of the last slot.
According to the method, when the network side equipment transmits the Ratematch resource through the PDSCH scheduled by the multi-time slot, and each time slot contains the Ratematch resource which can be multiplexed as the interference measurement resource, the interference measurement can be performed only on the interference measurement resource of the last time slot, and therefore the power consumption of the terminal is effectively reduced.
As shown in fig. 11, the network side device triggers the terminal to perform interference measurement through DCI signaling, and after the terminal receives the measurement deactivation indication in slot 1, the terminal performs interference measurement on the Ratematch resource in the last slot 14.
And fifthly, after the network side equipment configures a plurality of Ratematch resources for the terminal, the DCI signaling is sent to the terminal to indicate the terminal to carry out interference measurement on the configured Ratematch resources.
Optionally, the network side device indicates, through the DCI, information for triggering a Ratematch resource, so that the terminal determines, according to the information for triggering the Ratematch resource, a Ratematch resource that can be reused as an interference measurement resource in a corresponding Ratematch group, and performs interference measurement on the determined interference measurement resource.
Correspondingly, after receiving the information that the network side equipment triggers the Ratematch resources through the DCI indication, the terminal determines the Ratematch resources which can be multiplexed as interference measurement resources in the corresponding Ratematch group according to the information that the Ratematch resources are triggered; and the terminal carries out interference measurement on the determined interference measurement resource.
In specific implementation, after the network side device configures a plurality of Ratematch resources for the terminal, the plurality of Ratematch resources may be grouped, and meanwhile, information of the Ratematch resources is triggered through DCI indication, and control over the plurality of multiplexing resources is simultaneously achieved.
As shown in fig. 12, when the base station configures a Ratematch resource, ids of the Ratematch resources included in the Ratematch resource group1 are Id1 and Id2, respectively, and ids included in the Ratematch resource group2 are Id3, where the Ratematch resources of Id1 and Id3 can be reused as interference measurement, and a Rate matching indicator2bit (2-bit Rate matching indicator) is set to indicate whether two sets of Ratematch resources perform interference measurement, respectively, and when the values of the Rate matching indicator2bit in DCI take the following values, specific operations are as follows:
when the value is 11, triggering a Ratematch resource group1 and a Ratematch resource group2 to carry out interference measurement;
when the value is 10, only triggering a Ratematch resource group2 to carry out interference measurement;
when the value is 01, only triggering the Ratematch resource group1 to carry out interference measurement;
when the value is 00, neither the Ratematch resource group1 nor the Ratematch resource group2 triggers the interference measurement.
In a specific implementation, the slot2 network side device triggers information of a Ratematch resource through DCI, and the terminal determines that a value of a Rate matching indicator2bit is 11 according to the information of the triggered Ratematch resource, so that the UE is triggered to perform interference measurement on Ratematch pattern Id1 and Id3 corresponding to Ratematch pattern group1 and Ratematch pattern group2 at the same time.
In addition, the ZP CSI-RS resource and the Ratematch resource are also used as the reusable interference measurement resource, and at this time, the instruction for instructing the trigger terminal to perform interference measurement needs to be common to both.
