technical field

The present invention relates to the technical field of wireless communication, and in particular, to a method and device for interference measurement.

Background technique

In a dynamic TDD (Time Division Duplexing) system, if the base station side learns the 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. At present, there are mainly two methods for CLI measurement reporting between UE-UE (user and user) in the prior art: based on SRS-RSRP (SRS Reference Signal Receiving Power, sounding reference signal received power) and RSSI (Received Signal Receiving Power) Strength Indicator, received signal strength) measurement reporting method. Among them, RSRP refers to the linear average value of signal power received on all REs (resource elements, resource elements) carrying reference signals; RSSI refers to all signals (including reference signals and data signals) received in the Symbol (symbol) , adjacent cell interference signal, noise signal, etc.) linear average value, referring to the received signal strength indication.

SRS-RSRP-based interference measurement reporting needs to configure a specific reference signal for the interferer UE, for example, by configuring an SRS (Sounding Reference Symbol, sounding reference signal) for interference measurement.

However, according to the existing 5G NR (New Radio, new air interface) standard, RSSI is usually obtained by RSRP calculation in the prior art, and RSRQ (Reference Signal Received Quality, reference signal received quality) is calculated in further joint RSRP, and then Layer 1 reporting, and reporting at layer 1 mainly reports RSRP or RSRQ. However, this RSSI may contain both the same cell interference and the different cell interference. For the interference management of dynamic TDD, the cross-link interference between users is expected to be obtained.

To sum up, there is no solution for measuring cross-link interference between users in the prior art.

RSRP refers to the linear average value of the signal power received on all REs carrying the reference signal; RSSI refers to the power of all signals (including reference and data signals, adjacent cell interference signals, noise signals, etc.) received in the Symbol. Linear average, referring to the received signal strength indication.

SRS-RSRP-based interference measurement reporting needs to configure a specific reference signal for the interferer UE, for example, by configuring an SRS (Sounding Reference Symbol, sounding reference signal) for interference measurement.

However, according to the existing 5G NR (New Radio, new air interface) standard, RSSI is usually obtained by RSRP calculation in the prior art, and RSRQ (Reference Signal Received Quality, reference signal received quality) is calculated in further joint RSRP, and then Layer 1 reporting, and reporting at layer 1 mainly reports RSRP or RSRQ. However, this RSSI may include both the same cell interference and the different cell interference.

A network-side device 101, configured to determine a zero-power reference signal resource that can be multiplexed as an interference measurement resource; the network-side device configures the interference measurement resource for the terminal, so that the terminal is on the interference measurement resource Perform interference measurements.

In the above method, the network side device determines zero-power reference signal resources that can be multiplexed as interference measurement resources, and configures the interference measurement resources for the terminal, then the terminal determines the interference measurement resources configured by the network side device, and configures the interference measurement resources in the The interference measurement is performed on the interference measurement resource. In this way, the network-side device first determines the zero-power reference signal resources that can be multiplexed as interference measurement resources, and then configures the terminal with specific zero-power reference signal resources for interference measurement, so that the terminal can reuse the received cell. The used zero-power reference signal resources are used as interference measurement resources, and interference measurement is performed on the resources to obtain interference measurement information. In this way, when the uplink and downlink transmission directions between the serving cell of the terminal and the adjacent cells are inconsistent, the terminal interference measurement obtains the cross-link interference between the terminal and the users of the adjacent cells, so that the cross-link interference between users can be obtained. plan.

In a specific implementation, the zero-power reference signals that can be multiplexed into interference measurement resources include, but are not limited to, ZP CSI-RS and/or Ratematch signals. The signal power of the local cell received on the REs of the ZP CSI-RS and/or Ratematch signals is all zero, that is, the REs of the ZP CSI-RS and/or Ratematch signals are all in an idle state. After multiplexing the ZP CSI-RS resources and/or Ratematch resources as interference measurement resources, if the uplink and downlink transmission directions between the serving cell of the terminal and the adjacent cells are inconsistent, what is obtained is the intersection between the terminal and the users of the adjacent cells. link interference, thus providing a solution for measuring cross-link interference between users.

The two resources will be described separately below.

1. Multiplexing ZP CSI-RS resources into interference measurement resources.

In a specific implementation, the network side device determines ZP CSI-RS resources that can be multiplexed as interference measurement resources, wherein the interference measurement resources are part or all of the resources that carry the ZP CSI-RS resources.

Correspondingly, the terminal determines whether the corresponding ZP CSI-RS resource can be multiplexed as interference measurement according to the parameter value in the ZP CSI-RS resource configured by the network side device for indicating whether it can be multiplexed as interference measurement. resource.

In the above method, the network side device configures the ZP CSI-RS resources that can be multiplexed as interference measurement through the parameter value configured in the high-level signaling to indicate whether it can be multiplexed as interference measurement; Correspondingly, the terminal will The parameter value configured by the high layer signaling to indicate whether it can be multiplexed as interference measurement, and determine whether the corresponding resource can be multiplexed as interference measurement resource. In this way, the terminal can further select the ZP CSI-RS resources for interference measurement from the ZP CSI-RS resources that can be multiplexed as interference measurement resources, and finally realize the interference measurement on the ZP CSI-RS resources. The obtained It is the cross-link interference between the terminal and the adjacent cell users.

For example: when configuring ZP CSI-RS resources in high-layer signaling, an enumerated parameter 1 is introduced to indicate whether the ZP CSI-RS resources can be used for interference measurement. When the value is on, it indicates that the ZP CSI-RS resources are available. For interference measurement; when the value is off, it indicates that the ZP CSI-RS resource cannot be used for interference measurement.

Further, after configuring and determining all the ZP CSI-RS resources that can multiplex the interference measurement resources, the network side device will also configure the interference measurement resources for the terminal before performing the interference measurement, so that the terminal can perform the interference measurement. Interference measurements are performed on the interference measurement resources.

Wherein, the interference measurement period is the same as the bearer ZP CSI-RS resource period; or the interference measurement period is an integer multiple of the bearer ZP CSI-RS resource period.

In this way, a suitable interference measurement period can be set as required in the specific implementation process.

Example 1: As shown in Figure 2, the network side equipment is configured with periodic ZP CSI-RS resources with a period of 1 slot, and the ZP CSI-RS resources can be multiplexed into interference measurement resources. The interference measurement period is the same as the ZP CSI-RS resource period. If they are consistent, the terminal performs interference measurement on the ZP CSI-RS resources of each time slot.

is the number of subframes in a slot.

Among them, the corresponding time slot of the terminal is affected by the system parameter μ.

Example 3: As shown in Figure 4, the device on the network side activates the terminal to perform an interference measurement on the ZP CSI-RS resource through MAC-CE signaling. The UE receives the MAC-CE signaling in slot n, and then the terminal in slot n After +5, start to do 1 interference measurement on the ZP CSI-RS resource.

Optionally, after configuring the interference measurement resource and the number of times of interference measurement for the terminal through MAC CE signaling, if the number of times of interference measurement is 1, the interference measurement may also be moved to the last time slot for operation.

As shown in Figure 6, the device on the network side activates the terminal to perform an interference measurement on the ZP CSI-RS resource through the MAC-CE signaling. The UE receives the MAC-CE signaling in slot n, and then the terminal slot in the last time slot. An interference measurement is performed on n+6.

Optionally, the network side device sends an activation measurement indication through a 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 indication sent by the network side device through the MAC CE.

In the specific implementation, when the terminal receives the activation measurement indication sent by the network side device through the MAC CE, it prepares to perform interference measurement on the configured interference measurement resources, and continues to perform interference measurement on each Interference measurement is performed on the ZP CSI-RS resources of the slot.

Further, when the terminal receives the signaling sent by the network side device indicating to stop the interference measurement, the terminal stops the interference measurement.

Optionally, the network side device sends a deactivation measurement indication through a MAC CE, so that the terminal stops performing interference measurement on the configured interference measurement resource.

Correspondingly, after receiving the deactivation measurement indication 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, through the above method, the network side device can flexibly instruct the terminal to perform interference measurement when needed, and at the same time can instruct the terminal to stop the interference measurement. In this way, the number of measurements can be minimized while meeting the requirements of interference measurement, and the number of measurements of the terminal can be reduced to the greatest extent possible. energy loss.

For example, as shown in Figure 5, the network side device activates the terminal to perform interference measurement on ZP CSI-RS resources through MAC-CE signaling, the UE receives the activation measurement instruction at slot n, and starts at slot n+5 in the reusable Perform interference measurement on ZP CSI-RS resources for interference measurement resources;

The network side device sends the deactivation measurement indication to the terminal through MAC-CE signaling. After the terminal receives the deactivation measurement indication in slot n+6, the terminal stops performing interference measurement on the ZP CSI-RS resources in slot n+9.

(4) After configuring the ZP CSI-RS resources multiplexed as interference measurement resources for the terminal, the network side device sends DCI signaling to the terminal to instruct the terminal to perform interference measurement on the configured ZP CSI-RS resources.

Optionally, if the network side device sends ZP CSI-RS resources on PDSCH scheduled in multiple time slots, and each time slot includes ZP CSI-RS resources that can be multiplexed as interference measurement resources, the network side device The terminal is instructed through DCI to perform interference measurement on the interference measurement resource of the last time slot.

The interference measurement is performed on the interference measurement resource, thereby effectively reducing the power consumption of the terminal.

As shown in Figure 6, the network side device triggers the terminal to perform interference measurement through DCI signaling. After the terminal receives the deactivation measurement indication in slot n, the terminal performs interference measurement on the ZP CSI-RS resource of slot n+6 in the last time slot. .

2. Multiplexing Ratematch resources into interference measurement resources.

In a 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 the resources in the Bearing Ratematch resource.

Optionally, the network-side device configures the Ratematch resources in the Ratematch resources that can be multiplexed as interference measurement resources by configuring a parameter value in the Ratematch resources for indicating whether multiplexing can be used as interference measurement resources.

Correspondingly, the terminal determines whether the corresponding Ratematch resource can be multiplexed as an interference measurement resource according to a parameter value in the Ratematch resource configured by the network-side device for indicating whether it can be multiplexed as an interference measurement resource.

In the above method, the network side device configures the Ratematch resource that can be multiplexed as interference measurement through the parameter value configured in the high-level signaling to indicate whether it can be multiplexed as interference measurement; Correspondingly, the terminal will The configured parameter value to indicate whether it can be multiplexed as interference measurement, and determine whether the corresponding resource can be multiplexed as interference measurement resource. In this way, the terminal can further select the Ratematch resource for interference measurement from the Ratematch resource that can be multiplexed as the interference measurement resource, and finally implement the interference measurement on the Ratematch resource. Cross link interference.

For example, when the high-layer signaling configures the RateMatch pattern, a new high-layer parameter is introduced to indicate whether the RateMatch resource of the corresponding RateMatchPatternId can be multiplexed as interference measurement.

For example, an enumerated high-level parameter interference CLI-info is introduced, and its value is {on, off}, and the UE determines the corresponding behavior on the RateMatch resource by judging the value of the received interference CLI-info.

That is, when the value of the interference CLI-info is on, it means that the UE performs interference measurement on this RateMatch pattern; when the value of the interference CLI-info is off, it means that the UE performs a Ratematch on this RateMatch pattern.

Further, after configuring and determining all the Ratematch resources that can reuse the interference measurement resources, the network side device will also configure the interference measurement resources for the terminal before performing the interference measurement, so that the terminal can perform the interference measurement in the said terminal. The interference measurement is performed on the interference measurement resource.

There are various ways in which the network side device continues to configure the interference measurement resource for the terminal, which will be described separately below.

(1) 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.

Wherein, the interference measurement period is the same as the bearer Ratematch resource period; or the interference measurement period is an integer multiple of the bearer Ratematch resource period.

In this way, a suitable interference measurement period can be set as required in the specific implementation process.

Example 1: As shown in Figure 7, the network side device is configured with periodic Ratematch resources with a period of 1 slot, and the Ratematch resources can be multiplexed into interference measurement resources. The interference measurement period is the same as the Ratematch resource period. Interference measurement is performed on the Ratematch resource of the slot.

Example 2: As shown in Figure 8, the network-side device is configured with periodic Ratematch resources with a period of 1 slot, and the Ratematch resources can be multiplexed into interference measurement resources, and the interference measurement period is twice the Period of the Ratematch resources. Interference measurement is performed on the Ratematch resource of the corresponding time slot at an interval of one time slot.

(2) The network-side device configures interference measurement resources for the terminal through MAC CE signaling.

Optionally, the network side device configures the number of measurements for the terminal through the MAC CE.

Correspondingly, the terminal performs interference measurement on the interference measurement resource configured by the network side device according to the measurement times configured by the network side device through the MAC CE.

In the above method, the network side device configures the number of measurements for the terminal through the MAC CE, and after receiving the MAC CE signaling configured with the number of measurements, the terminal parses to obtain the number of measurements configured, and performs on the determined interference measurement resource according to the number of measurements configured. Interference measurement.

Further, there is a delay when the terminal receives the MAC CE signaling of the network side device to the time when the terminal performs interference measurement in response to the MAC CE signaling.

之后干扰测量资源上进行干扰测量；Optionally, after the terminal receives the activation measurement indication sent by the network side device through the MAC CE at slot n,

Then, perform interference measurement on the interference measurement resource;

为一个时隙中的子帧数。in,

is the number of subframes in a slot.

Among them, the corresponding time slot of the terminal is affected by the system parameter μ.

Example 3: As shown in Figure 9, the network side device activates the terminal to perform two interference measurements on the Ratematch resource through MAC-CE signaling, the UE receives the MAC-CE signaling in slot n, and then the terminal after slot n+5 Start to perform three interference measurements on the Ratematch resource.

(3) After configuring the Ratematch resource multiplexed as the interference measurement resource for the terminal, the network side device sends a MAC-CE signaling to the terminal to instruct the terminal to perform interference measurement on the configured Ratematch resource.

Optionally, the network side device sends an activation measurement indication through a 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 indication sent by the network side device through the MAC CE.

In the specific implementation, when the terminal receives the activation measurement indication sent by the network side device through the MAC CE, it prepares to perform interference measurement on the configured interference measurement resources, and continues to perform interference measurement on each Interference measurement is performed on the Ratematch resource of the time slot.

Further, when the terminal receives the signaling sent by the network side device indicating to stop the interference measurement, the terminal stops the interference measurement.

Optionally, the network side device sends a deactivation measurement indication through a MAC CE, so that the terminal stops performing interference measurement on the configured interference measurement resource.

Correspondingly, after receiving the deactivation measurement indication 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, through the above method, the network side device can flexibly instruct the terminal to perform interference measurement when needed, and at the same time can instruct the terminal to stop the interference measurement. In this way, the number of measurements can be minimized while meeting the requirements of interference measurement, and the number of measurements of the terminal can be reduced to the greatest extent possible. energy loss.

For example, as shown in Figure 10, the network side device activates the terminal to perform interference measurement on the Ratematch resource through MAC-CE signaling, the UE receives the activation measurement instruction in slot 1, and starts to perform the interference measurement on the Ratematch resource in slot 5;

The device on the network side sends the deactivation measurement indication to the terminal through MAC-CE signaling. After the terminal receives the deactivation measurement indication in slot 10, the terminal stops performing interference measurement on slot 14 and subsequent Ratematch resources.

(4) After configuring the Ratematch resources multiplexed as interference measurement resources for the terminal, the network side device sends DCI signaling to the terminal to instruct the terminal to perform interference measurement on the configured Ratematch resources.

Optionally, if the network-side device sends Ratematch resources on PDSCH scheduled in multiple time slots, and each time slot includes Ratematch resources that can be multiplexed as interference measurement resources, the network-side device indicates to the terminal through DCI. The interference measurement is performed on the interference measurement resource of the last slot.

Correspondingly, if the terminal receives a Ratematch resource indicated by the network side device through the DCI to be sent on the PDSCH scheduled in multiple time slots, and each time slot includes a Ratematch resource that can be multiplexed as an interference measurement resource, the terminal The interference measurement is performed on the interference measurement resource of the last slot.

(5) After the network side device configures multiple Ratematch resources for the terminal, it instructs the terminal to perform interference measurement on the configured Ratematch resources by sending DCI signaling to the terminal.

Optionally, the network side device indicates the information that triggers the Ratematch resource through the DCI, so that the terminal determines the Ratematch resource that can be multiplexed as the interference measurement resource in the corresponding Ratematch group according to the information that triggers the Ratematch resource, and configures it in the corresponding Ratematch group. The interference measurement is performed on the determined interference measurement resource.

Correspondingly, after receiving the information that the network-side device instructs to trigger the Ratematch resource through the DCI, the terminal determines, according to the information that triggers the Ratematch resource, the Ratematch resource that can be multiplexed as the interference measurement resource in the corresponding Ratematch group; The terminal performs interference measurement on the determined interference measurement resource.

In a specific implementation, after the network-side device configures multiple Ratematch resources for the terminal, the multiple Ratematch resources can be grouped, and the information that triggers the Ratematch resources is indicated through the DCI, so as to realize the control of multiple multiplexed resources at the same time.

As shown in Figure 12, when the base station configures the Ratematch resources, the Ids of the Ratematch resources contained in the Ratematch resource group 1 are Id1 and Id2 respectively, and the Ids contained in the Ratematch resource group 2 are Id3. The Ratematch resources of Id1 and Id3 can be duplicated. It is used for interference measurement, and by setting the Rate matching indicator2bit (a 2-bit rate matching indicator), it indicates whether the two sets of Ratematch resources are used for interference measurement, and when the values of the Ratematching indicator 2bit in the DCI take the following values, the specific operations are as follows: Show:

When the value is 11, both Ratematch resource group 1 and Ratematch resource group 2 are triggered to perform interference measurement;

When the value is 10, only Ratematch resource group 2 is triggered for interference measurement;

When the value is 01, only Ratematch resource group 1 is triggered for interference measurement;

When the value is 00, neither Ratematch resource group 1 nor Ratematch resource group 2 triggers interference measurement.

In the specific implementation, the device on the network side in slot 2 triggers the information of the Ratematch resource through the DCI, and the terminal determines that the value of the Rate matching indicator2bit is 11 according to the information that triggers the Ratematch resource, so the UE simultaneously triggers the RateMatch pattern Id1 and Id3 corresponding to the RateMatchPatternGroup1 and RateMatchPatternGroup2 of the UE. interference measurement.

In addition, the ZP CSI-RS resource and the Ratematch resource are simultaneously used as interference measurement resources that can be multiplexed. In this case, the instruction for triggering the terminal to perform interference measurement needs to be common to both.
