Description

Method and equipment for reporting interference measurement

Technical Field

The present invention relates to the field of wireless communications technologies, and in particular, to a method and apparatus for reporting interference measurement.

Background

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 the communication cannot be performed, and if the base station side acquires the cross link interference information between the terminals, the base station side can be beneficial to operations such as dynamic resource allocation, cooperative scheduling and the like, so that the system performance is improved.

Currently, two main approaches are given for cross-link interference measurement reporting between UEs-UEs (user equipments): based on the measurement reporting mode of SRS-RSRP (Reference Signal Receiving Power, reference signal received power) and layer-one RSSI (Received Signal Strength Indicator, received signal strength). The CLI (Cross Link Interference ) measurement report based on SRS-RSRP needs to configure a specific measurement reference signal for the interference source UE, and the corresponding interfered UE needs to configure an interference measurement resource for CLI measurement, so that the measurement reference signal and measurement resource configuration cost is large; another measurement reporting mode based on layer one RSSI is defined according to the existing NR standard, and the function of layer one RSSI is to calculate RSRQ (Reference Signal Received Quality, RSRQ, reference signal receiving quality) by combining RSRP, and is mainly used for a higher layer, and when reporting layer 1, the RSRP or RSRQ is mainly reported, and there is no specific reporting mode corresponding to layer one RSSI.

For interference management of dynamic TDD (Time Division Duplexing, time division duplex), cross link interference information between cells is obtained, and meanwhile cross link interference between users is expected to be obtained, and layer-one RSSI measurement is mainly implemented by measuring on interference measurement resources configured by interfered UEs, and does not depend on configuration of measurement reference signals, so that the interference management requirement of dynamic TDD is met, but no specific reporting mode corresponding to RSSI exists at present. In addition, although the RSSI value may be calculated according to the relation between the RSSI and the RSRP, RSRQ in the existing measurement reporting manner, the RSSI may include both the same-cell interference measured by using the NZP CSI-RS and different-cell interference measured by using the CSI-IM.

In summary, there is currently no method for reporting interference measurement for RSSI.

Detailed Description

For the purpose of promoting an understanding of the principles and advantages of embodiments of the invention, reference will now be made in detail to the embodiments of the invention, some but not all of which are illustrated in the accompanying drawings. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are intended to be within the scope of the embodiments of the present invention.

Some words appearing hereinafter are explained:

(1) The term "plurality" in the embodiments of the present application means two or more, and other adjectives are similar thereto.

(2) "and/or", describes an association relationship of an association object, and indicates that there may be three relationships, for example, a and/or B, and may indicate: a exists alone, A and B exist together, and B exists alone. The character "/" generally indicates that the context-dependent object is 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 multiplexed into interference measurement in the invention.

(4) In this embodiment, "Ratematch Pattern" is mainly used for rate matching in the prior art, that is, the user is in a null state on the resource that receives rateatch, and may be multiplexed into interference measurement in the present invention.

In the prior art, a rateratch of a CSI-RS for a PDSCH (Physical Downlink Shared Channel ) has been defined in NR to avoid interference when neighbor cells perform operations such as channel measurement on the same RE (resource element). That is, if the RE resource can receive the neighbor cell user or base station information, the information received on the RE resource can be regarded as interference, and thus the interference measurement operation can be completed. If the interference information is determined by completing RSRP measurement according to the prior art, the corresponding measurement reference signals are required to be configured by the neighboring cell UE, the measurement reference signals and the measurement resource configuration overhead are larger, and by performing RSSI measurement on the RE resource, the measurement reference signal configuration is not required, and the interference measurement operation is completed more simply.

However, according to the definition of the RSSI in the existing protocol, only the RSSI is measured at present, but no interference reporting is performed, so the embodiment of the present invention provides a method for reporting layer-one RSSI interference measurement.

As shown in fig. 1, an embodiment of the present invention provides a first interference measurement system, which includes:

the terminal 100 is configured to perform layer-one RSSI interference measurement to obtain interference measurement information; and reporting the obtained interference measurement information corresponding to the layer-one RSSI to network side equipment through a transceiver.

The network side device 101 is configured to receive interference measurement information reported by the terminal through the transceiver; and performing interference deletion or interference suppression according to the interference measurement information.

By the method, the interference measurement information is obtained by the terminal through the layer one RSSI interference measurement, and the obtained interference measurement information corresponding to the layer one RSSI is reported to the network side equipment, so that the network side equipment performs interference deletion or interference suppression according to the interference measurement information.

In the embodiment of the invention, the terminal performs the layer-one RSSI interference measurement to obtain the interference measurement information, and mainly performs the layer-one RSSI interference measurement on the interference measurement resources configured by the network side equipment. Wherein the interference measurement resources are part or all of the resources carrying the ZP CSI-RS and/or part or all of the resources carrying ratematch pattern.

In the embodiment of the present invention, the layer-one RSSI is redefined.

Specifically, the terminal determines a linear average of all signal powers received on a resource multiplexed as interference measurement in a resource carrying ZP CSI-RS or ratematch pattern as a layer-one RSSI.

In the process that the network side equipment configures the interference measurement resources for the terminal for interference measurement, the network side equipment configures the interference measurement resources for the terminal through parameter values in high-layer signaling, wherein the parameter values are used for indicating whether the parameter values can be multiplexed into the interference measurement resources.

For example, when the network side equipment configures the ZP CSI-RS resource, an enumeration parameter 1 is introduced to indicate whether the ZP CSI-RS resource is available for interference (including CLI) measurement, and when the value of the enumeration parameter is on, the enumeration parameter is used to indicate that the ZP CSI-RS resource is available for interference (including CLI) measurement; taking off indicates that the ZP CSI-RS resource is not available for interference (including CLI) measurements.

After receiving the interference measurement resource sent by the network side, the terminal determines whether the corresponding resource is the interference measurement resource according to the parameter value which is configured by the network side equipment through a higher layer and used for indicating whether the resource can be multiplexed into the interference measurement.

For example, the interference measurement resource received by the terminal is ZP CSI-RS resource, and the terminal determines whether multiplexing as interference measurement is possible according to the configuration of the enumeration parameter 1 of the ZP CSI-RS resource. If the parameter value of the enumeration parameter 1 is on, the interference measurement resource can be multiplexed, the terminal performs interference measurement on the corresponding ZP CSI-RS resource, and calculates an interference report value; and if the parameter value of the enumeration parameter 1 is off, indicating that the interference measurement resources can not be multiplexed, and not performing interference measurement.

By the method, when the network side equipment configures the interference measurement resources, the parameter value used for indicating whether the interference measurement resources can be multiplexed into the interference measurement resources is increased, so that the terminal can determine whether the interference measurement resources can be multiplexed through the parameter value after receiving the interference measurement resources sent by the network side equipment.

In the embodiment of the present invention, after determining that the interference measurement resource is reusable, the terminal performs layer one RSSI interference measurement on the reusable interference measurement resource, and reports the interference measurement information obtained based on the layer one RSSI interference measurement, where the reporting manner is different and may be divided into different situations, which are described below respectively.

The specific reporting mode is selected, and the protocol between the network side equipment and the terminal can be determined.

Case 1: the terminal takes the layer one RSSI as the interference measurement information.

That is, when the terminal performs layer one RSSI interference measurement on the reusable resource, a layer one RSSI value is calculated and reported to the network side device as interference measurement information.

Case 2: the terminal takes the determined difference value between the layer one RSSI and a target value as the interference measurement information, wherein the target value is reported layer one RSSI or RSRP.

For example, the terminal selects a maximum layer one RSSI value from the 5 reported layer one RSSI values as a target value, and assumes that the 5 reported layer one RSSI values are 8, 9, 6, 7, and 5, where the maximum layer one RSSI value is 9, so that the target value is 9, after determining the target value, when the terminal performs layer one RSSI interference measurement on the reusable resource, the terminal calculates that the layer one RSSI value is 7, and a difference value between the calculated layer one RSSI value and the target value is 2, and according to the reporting manner of case 2, the difference value 2 is reported to the network side device as interference measurement information.

Through the reporting mode of the case 2, the differential value is reported each time, so that resources are saved and system overhead is reduced compared with the method for directly reporting the RSSI value of a specific layer one.

Case 3: the terminal uses information for representing the magnitude relation between the layer-one RSSI and a set threshold value as the interference measurement information.

For example, a threshold is set, and the magnitude relation between the layer one RSSI value obtained by performing the layer one RSSI interference measurement and the threshold is represented by 1 bit, and the layer one RSSI value obtained by performing the layer one RSSI interference measurement is greater than or equal to the threshold assuming that the value of 1 bit is 1, and the layer one RSSI value obtained by performing the layer one RSSI interference measurement is less than the threshold assuming that the value of 1 bit is 0. For example, the set threshold is 7, and the layer one RSSI value obtained by the terminal performing the layer one RSSI interference measurement is 8 and greater than the threshold, so that the information of the magnitude relation between the layer one RSSI and the set threshold is 1 is used as the interference measurement information to report to the network side device.

In the embodiment of the present invention, when the terminal performs layer one RSSI interference measurement on the reusable resource, after calculating the layer one RSSI value, there are situations that the layer one RSSI value is not reported to the network side device, and several kinds of situations are described below.

No report case 1: and after the terminal determines that the interference change is in the interference fluctuation range according to the layer-one RSSI interference measurement information, stopping reporting the interference measurement information to the network side equipment.

Specifically, the terminal determines that the interference change exceeds the interference fluctuation range according to the layer one RSSI interference measurement information, and stops reporting the interference measurement information to the network side device after determining that the interference change is in the interference fluctuation range according to the layer one RSSI interference measurement information, wherein the interference change is a difference value between the layer one RSSI interference measurement information and a target value.

For example, the target value is set to 8, the interference fluctuation range is set to 0-4, the layer one RSSI value obtained by the terminal performing the layer one RSSI interference measurement is set to 9, so as to obtain the interference variation as the difference value 1 between the layer one RSSI interference measurement information and the target value, and the interference variation is known to be within the interference fluctuation range, so that the reporting of the interference measurement information to the network side device is stopped.

No report case 2: and after the terminal determines that the layer one RSSI is larger than a set threshold, stopping reporting the interference measurement information to the network side equipment.

For example, a threshold is set, where the threshold is 7, if the layer one RSSI value obtained by the terminal performing the layer one RSSI interference measurement is 8 and is greater than the threshold, so that the information of the layer one RSSI of 8 is used as interference measurement information to report to the network side device, and if the layer one RSSI value obtained by the terminal performing the layer one RSSI interference measurement is 6 and is greater than the threshold, the terminal does not report.

After the terminal reports the interference measurement information to the network side device, the network side device receives the interference measurement information reported by the terminal, so that the network side device performs interference deletion or interference suppression according to the interference measurement information.

The network side device performs interference deletion or interference suppression in different subsequent manners according to different received interference measurement information, which are described below.

Mode 1: if the interference measurement information is layer one RSSI, the network side equipment performs interference deletion or interference suppression according to the layer one RSSI;

mode 2: if the interference measurement information is a difference value between the layer one RSSI and the target value, the network side equipment determines the layer one RSSI according to the preset target value and the difference value, and performs interference deletion or interference suppression according to the layer one RSSI.

Assuming that the target value determined by the network side device and the terminal is 7, the difference value is the difference between the layer one RSSI and the target value, and the interference measurement information received by the network side device and sent by the terminal is 2, the network side device may determine that the layer one RSSI value is 9 according to the target value 7, and the network side device performs interference deletion or interference suppression.

If the network side device and the terminal agree on the received information about the size relationship between the layer one RSSI and the set threshold, the network side device may determine whether to perform interference deletion or interference suppression according to the received information about the size relationship between the layer one RSSI and the set threshold reported by the terminal.

Specifically, if the interference measurement information is information for representing a magnitude relation between the layer one RSSI and the set threshold, the network side device determines that interference deletion or interference suppression is required after determining that the layer one RSSI is greater than the set threshold according to the received information, and if determining that the layer one RSSI is less than the threshold, determines that interference deletion or interference suppression is not required.

The method comprises the steps of setting a threshold, using 1 bit to represent the magnitude relation between a layer one RSSI value obtained by carrying out layer one RSSI interference measurement and the threshold, using 1 bit to represent that the layer one RSSI value obtained by carrying out layer one RSSI interference measurement is larger than or equal to the threshold when the value of the 1 bit is 1, and using 1 bit to represent that the layer one RSSI value obtained by carrying out layer one RSSI interference measurement is smaller than the threshold when the value of the 1 bit is 0. And if the network side equipment receives that the interference measurement information reported by the terminal is 1, the layer one RSSI value is larger than a threshold value, and interference deletion or interference suppression is needed.

In the embodiment of the invention, after the network side equipment determines that interference deletion or interference suppression is required according to the received information for representing the magnitude relation between the layer one RSSI and the set threshold, the network side equipment can send an instruction for reporting the interference measurement information in the mode 1 or the mode 2 to the terminal, so that the network side equipment determines the specific layer one RSSI according to the interference measurement information after receiving the interference measurement information reported in the mode 1 or the mode 2 by the terminal, and performs interference deletion or interference suppression.

In some possible implementations, aspects of a method for reporting interference measurements provided by the embodiments of the present invention may also be implemented in the form of a program product, which includes program code for causing a computer device to perform the steps of the method for reporting interference measurements according to the various exemplary embodiments of the present invention as described in this specification, when the program code is run on the computer device.
