Background

In some communication systems, for example, new radio access technology (NR) of the fifth generation (5G) communication system, in order to combat path loss in high frequency scenarios, gain may be obtained through beamforming. Specifically, the network device may send a measurement signal through different reference signal resources, the terminal device may report a part of the reference signal resources with a larger reference signal received power to the network device through beam measurement, and the network device may select one or more corresponding beams in the part of the reference signal resources to perform data transmission. In the packet reporting mode, the terminal device reports two reference signal resources that can be received by the terminal device at the same time, and the network device uses the two reference signal resources to transmit data to the terminal device at the same time.

However, in some scenarios, such as a multi-user multi-input multi-output (MU-MIMO) scenario, the network device may want to acquire more information about the two reference signal resources, so as to perform beam management more reasonably and improve efficiency of multi-user transmission.

The application provides a measurement reporting method and a communication device, and by reporting interference information of channel resources, network equipment can perform reasonable interference management and improve the efficiency of multi-user transmission.

In a first aspect, a measurement reporting method is provided, where the method includes: the terminal equipment receives measurement configuration information sent by the network equipment; the terminal equipment determines n target channel resources which can be simultaneously received by the terminal equipment and determines interference information corresponding to the n target channel resources according to the measurement configuration information, wherein n is more than or equal to 2 and is a positive integer; and the terminal equipment reports the indexes of the n target channel resources and the interference information corresponding to the n target channel resources.

In a second aspect, a measurement reporting method is provided, where the method includes: the network equipment sends measurement configuration information to the terminal equipment; the network device receives indexes of n target channel resources reported by the terminal device and interference information corresponding to the n target channel resources, the n target channel resources can be received by the terminal device at the same time, n is not less than 2, and n is a positive integer.

Wherein the measurement configuration information may indicate N channel resources and M interference resources. For example, the measurement configuration information may include indexes of the N channel resources and indexes of the M channel resources. Wherein N is a positive integer greater than or equal to 2, and M is a positive integer. The N target channel resources belong to the N channel resources.

The measurement configuration information may also include one or more of the following: the method includes a method for calculating the number N of channel resources to be reported (N is greater than or equal to 2 and less than N, and N is an integer), the number M of interference resources to be reported (M is greater than or equal to 1 and less than or equal to M, and M is an integer), the type of the interference resources to be reported, and the signal to interference plus noise ratio (SINR) or a reporting format of a measurement result. The reporting format of the measurement result may include a reporting arrangement of the interference resources and/or a reporting arrangement of the equivalent SINR, that is, what arrangement the interference resources are reported in, and what arrangement the equivalent SINR is reported in. The information may be defined by a protocol or may be a default value, which is not limited in the present application.

Wherein, the type of the interference resource may be a strong interference resource or a weak interference resource. The strong interference resource refers to a resource with strong interference (e.g., a small equivalent SINR) caused by n target channel resources (i.e., n channel resources reported by the terminal device). The weak interference resource refers to a resource that causes weak interference (e.g., the equivalent SINR is large) to the n target channel resources.

According to the measurement reporting method provided by the application, the terminal equipment can determine the interference information corresponding to the n target channel resources according to the measurement configuration information sent by the network equipment, and based on the interference information, the network equipment can carry out reasonable interference management, so that the efficiency of multi-user transmission is improved. For example, the interference information may include an index of an interference resource with a large interference degree (for example, a small equivalent SINR) to the n target channel resources, so that when the network device performs multi-user transmission, it may try to avoid using the target channel resource and the interference resource reported by the terminal device at the same time. For another example, the interference information may include an index of an interference resource with a small interference degree (for example, a large equivalent SINR) to the n target channel resources, so that when the network device performs multi-user transmission, the target channel resource and the interference resource reported by the terminal device may be used at the same time.

In a third aspect, a measurement reporting method is provided, where the method includes: the method comprises the steps that terminal equipment receives first measurement configuration information sent by network equipment; the terminal equipment determines n target channel resources which can be simultaneously received by the terminal equipment according to the first measurement configuration information, wherein n is more than or equal to 2 and is a positive integer; the terminal equipment receives second measurement configuration information sent by the network equipment; and the terminal equipment determines the interference information corresponding to the n target channel resources according to the second measurement configuration information.

The first measurement configuration information may indicate N channel resources, for example, the first measurement configuration information may include indexes of the N channel resources. Wherein N is a positive integer greater than or equal to 2. The N target channel resources belong to the N channel resources.

The second measurement configuration information may indicate M interference resources, for example, the first measurement configuration information may include indexes of the M interference resources. Wherein M is a positive integer.

The first measurement configuration information may further include the number N of channel resources to be reported (N is greater than or equal to 2 and less than N, and N is an integer). It should be understood that the number n of channel resources to be reported may also be specified by a protocol or adopt a default value, which is not limited in this application.

The second quantity configuration information may also include one or more of: the number M of the interference resources to be reported (M is more than or equal to 1 and less than or equal to M, and M is an integer), the type of the interference resources to be reported, and a signal to interference plus noise ratio (SINR) calculation method or a measurement result reporting format. The reporting format of the measurement result may include a reporting arrangement of the interference resources and/or a reporting arrangement of the equivalent SINR, that is, what arrangement the interference resources are reported in, and what arrangement the equivalent SINR is reported in. The information may be defined by a protocol or may be a default value, which is not limited in the present application.

Wherein, the type of the interference resource may be a strong interference resource or a weak interference resource. The strong interference resource refers to a resource with strong interference to n target channel resources (i.e., n channel resources reported by the terminal device). The weak interference resource refers to a resource which causes weak interference to the n target channel resources.

According to the measurement reporting method provided by the application, the terminal device can determine the interference information corresponding to the n target channel resources according to the first measurement configuration information and the second measurement configuration information sent by the network device, and based on the interference information, the network device can perform reasonable interference management, so that the efficiency of multi-user transmission is improved. For example, the interference information may include an index of an interference resource with a large interference degree (for example, a small equivalent SINR) to the n target channel resources, so that when the network device performs multi-user transmission, it may try to avoid using the target channel resource and the interference resource reported by the terminal device at the same time. For another example, the interference information may include an index of an interference resource with a small interference degree (for example, a large equivalent SINR) to the n target channel resources, so that when the network device performs multi-user transmission, the target channel resource and the interference resource reported by the terminal device may be used at the same time.

With reference to the first aspect to the fourth aspect, in some possible implementations, the interference information includes indexes of m interference resources, and/or equivalent SINRs of the n target channel resources under interference of each of the m interference resources, where m is a positive integer.

For example, the interference information may include only indexes of m interference resources; or, when the network device can identify which interference resource the equivalent SINR reported by the terminal device corresponds to, the interference information may only include the equivalent SINR of the n target channel resources under the interference of each interference resource in the m interference resources; alternatively, the interference information may include indexes of the m interference resources and equivalent SINRs of the n target channel resources under interference of each of the m interference resources.

Signaling overhead can be saved by reporting only the indexes of m interference resources. By reporting the equivalent SINR under the interference of each interference resource in the m interference resources, the network device can perform more reasonable beam management according to the equivalent SINRs, and provide multi-user transmission efficiency.

With reference to the first aspect to the fourth aspect, in some possible implementations, the interference information may include indexes of m interference resources, and/or SINRs of each target channel resource of the n target channel resources under interference of each interference resource of the m interference resources.

It should be understood that, the SINR of each target channel resource in the n target channel resources under the interference of each interference resource in the m interference resources, or the SINR of each target channel resource in the n target channel resources under the interference of each interference resource in the m interference resources, refers to n × m SINR calculated by taking each target channel resource in the n target channel resources as a channel and taking any interference resource k as interference. That is, for the interfering resource k, there is one SINR for each target channel resource.

With reference to the first aspect to the fourth aspect, in some possible implementations, the equivalent SINRs of the n target channel resources under the interference of any one interference resource k of the m interference resources may be at least one of:

the sum of SINRs of the n target channel resources under the interference of the interference resource k;

the maximum value of the SINR of the n target channel resources under the interference of the interference resource k;

the minimum value of SINR of the n target channel resources under the interference of the interference resource k; alternatively, the first and second electrodes may be,

and the average value of the SINRs of the n target channel resources under the interference of the interference resource k.

With reference to the first aspect, in certain implementations of the first aspect, the measurement configuration information includes indexes of M interference resources, where the M interference resources include the M interference resources, M is less than or equal to M, and M is an integer. And the terminal device determines the interference information corresponding to the n target channel resources according to the measurement configuration information, including: the terminal equipment determines n M SINRs of the n target channel resources under the interference of each interference resource in the M interference resources respectively; the terminal equipment determines M equivalent SINRs of the n target channel resources under the interference of each interference resource according to n × M SINRs of the n target channel resources under each interference resource; and the terminal equipment determines the interference information corresponding to the n target channel resources according to the M equivalent SINRs of the n target channel resources under the interference of each interference resource.

With reference to the third aspect, in some implementations of the third aspect, the second measurement configuration information includes indexes of M interference resources, where the M interference resources include the M interference resources, M ≦ M, and M is an integer. And the terminal device determines the interference information corresponding to the n target channel resources according to the second measurement configuration information, including: the terminal equipment determines n M SINRs of the n target channel resources under the interference of each interference resource in the M interference resources respectively; the terminal equipment determines M equivalent SINRs of the n target channel resources under the interference of each interference resource according to n × M SINRs of the n target channel resources under each interference resource; and the terminal equipment determines the interference information corresponding to the n target channel resources according to the M equivalent SINRs of the n target channel resources under the interference of each interference resource.

Illustratively, the terminal device may calculate the equivalent SINR by adopting any one of the following methods:

A. summation principle

That is, the equivalent SINR of the n target channel resources under the interference of any interference resource r in the M interference resources is equal to the sum of the SINR of the n target channel resources under the interference of the M channel resources.

Through the summation principle, the equivalent SINR can reflect the interference of the interference resource r to multiple target channel resources. For example, if the interference resource r has less interference to each target channel resource, the SINR of each target channel will be greater, and the equivalent SINR calculated by the summation principle is also greater. The interference magnitude of the interference resource r to each target channel resource can be determined through the equivalent SINR.

B. Principle of minimum

That is, the equivalent SINR of the n target channel resources under the interference of the interference resource r is equal to the minimum value of the SINR of the n target channel resources under the interference of the M channel resources, respectively.

When data is transmitted using a plurality of beams, if a plurality of beams transmit the same data, in order to ensure transmission reliability, data transmission may be performed based on the minimum value among SINRs of all beams, such as selecting a Modulation and Coding Scheme (MCS). In this case, the minimum SINR value of each beam is a key index for really determining the data transmission performance. In this case, the performance is best by adopting the minimum value principle to judge the interference of the interference resource k to the multiple target channel resources.

C. Principle of maximum value

That is, the equivalent SINR of the n target channel resources under the interference of the interference resource r is equal to the maximum SINR of the n target channel resources under the interference of the M channel resources, respectively.

When data is transmitted using a plurality of beams, if the plurality of beams transmit different data, in order to improve transmission throughput, data transmission may be performed based on a maximum value among SINRs of all the beams, such as selecting a Modulation and Coding Scheme (MCS). In this case, the maximum SINR of each beam is the key index for really determining the data transmission performance. In this case, the performance is best when the maximum principle is adopted to determine the interference of the interference resource k to the multiple target channel resources.

D. Principle of mean value

The equivalent SINRs of the n target channel resources under the interference of the interference resource r are equal to the average value of the SINRs of the n target channel resources under the interference of the M channel resources respectively. The average may be a linear average or a non-linear average, such as an equivalent average calculated based on a log-log function.

Through the average value principle, the equivalent SINR can reflect the interference level of the interference resource k to multiple target channel resources. For example, if the interference of the interference resource k to each target channel resource is small, the SINR of each target channel is large, and the equivalent SINR calculated by the average principle is also large. The interference magnitude of the interference resource k to each target channel resource can be determined through the equivalent SINR.

The SINR sum or the average value may be calculated in dB, or may be calculated as a linear value.

It should be understood that the terminal device may also determine the equivalent SINR in other manners, which is not limited in this application.

With reference to the first aspect to the fourth aspect, in some possible implementation manners, the M equivalent SINRs corresponding to the M interference resources are the maximum or minimum M equivalent SINRs among the M equivalent SINRs corresponding to the M interference resources.

Specifically, the M interference resources reported by the terminal device may be M interference resources with the smallest corresponding equivalent SINR among the M interference resources, or may be M interference resources with the largest corresponding equivalent SINR among the M interference resources. Specifically, whether the interference resource with the larger equivalent SINR or the interference resource with the smaller equivalent SINR is reported may be configured by the network device or may be specified by a default protocol.

If the m interference resources are interference resources with smaller equivalent SINR, then the network device may avoid using the target channel resources and the interference resources reported by the terminal device at the same time as much as possible when performing multi-user transmission. The interference information is an index of the interference resource with a larger equivalent SINR, so that the network device can simultaneously use the target channel resource and the interference resource reported by the terminal device when performing multi-user transmission. Therefore, through the interference information reported by the terminal equipment, the network equipment can carry out reasonable interference management and improve the efficiency of multi-user transmission.

With reference to the first aspect or the third aspect, in some implementation manners, the reporting, by the terminal device, interference information corresponding to the n target channel resources includes: and the terminal equipment reports the interference information corresponding to the n target channel resources according to the increasing or decreasing arrangement sequence of the m equivalent SINRs corresponding to the m interference resources.

Accordingly, with reference to the second aspect or the fourth aspect, in some implementation manners, the interference information corresponding to the n target channel resources is reported according to an increasing or decreasing ranking order of the m equivalent SINRs corresponding to the m interference resources.

For example, the terminal device may report the indexes of the m interference resources according to an increasing or decreasing ranking order of the m equivalent SINRs corresponding to the m interference resources. Further, the terminal device may also report the equivalent SINRs corresponding to the m interference resources according to an increasing or decreasing ranking order of the m equivalent SINRs corresponding to the m interference resources, that is, report the equivalent SINRs of the n target channel resources under the interference of each interference resource in the m interference resources.

Further, the index of the interference resource and the SINR (equivalent SINR or SINR of each target channel) corresponding to the interference resource may be arranged in a cross manner, that is, the index of each interference resource and the SINR corresponding to the interference resource are arranged together, or may not be arranged in a cross manner, that is, the indexes of all the interference resources are arranged together and all the SINRs are arranged together.

With reference to the first aspect or the third aspect, in some implementation manners, the reporting, by the terminal device, interference information corresponding to the n target channel resources includes: and the terminal equipment reports m equivalent SINRs corresponding to the m interference resources by adopting a differential reporting criterion.

Correspondingly, with reference to the second aspect or the fourth aspect, in some implementation manners, the m equivalent SINRs corresponding to the m interference resources are reported by using a differential reporting criterion.

And the m equivalent SINRs are reported through a difference criterion, so that the signaling overhead can be saved.

Thus, network device 110 and terminal device 120 may communicate via multiple antenna techniques.

It should be understood that the network device in the wireless communication system is a device deployed in a radio access network to provide wireless communication functions for terminal devices. Network devices include, but are not limited to: evolved Node B (eNB), Radio Network Controller (RNC), Node B (Node B, NB), Base Station Controller (BSC), Base Transceiver Station (BTS), Home Base Station (e.g., Home evolved NodeB, or Home Node B, HNB), BaseBand Unit (Base band Unit, BBU), Access Point (AP) in Wireless Fidelity (WIFI) system, etc., and may also be 5G, such as NR, gbb in system, or TRP, transmission Point (TRP or TP), one or a group of antennas (including multiple antennas, NB, or a transmission panel) of a Base Station in 5G system, such as a baseband unit (BBU), or a Distributed Unit (DU), etc. The network device may also be a wireless controller in a Cloud Radio Access Network (CRAN) scenario.

Since the information of the RRC layer eventually becomes or is converted from the information of the PHY layer, the higher layer signaling, such as the RRC layer signaling, may also be considered to be transmitted by the DU or the DU + CU under this architecture.

Before describing the embodiments of the present application, a brief description of several terms referred to in the present application will be provided.

1. Wave beam

A beam may be a spatial domain filter, or referred to as a spatial filter or spatial parameter. A beam for transmitting a signal may be referred to as a transmission beam (Tx beam), or may be referred to as a spatial domain transmission filter (spatial transmission filter) or a spatial transmission parameter (spatial transmission parameter); the beam used for receiving the signal may be referred to as a reception beam (Rx beam), or may be referred to as a spatial domain receive filter (spatial Rx parameter) or a spatial Rx parameter.

The transmit beam may refer to a distribution of signal strengths formed in different spatial directions after the signal is transmitted through the antenna, and the receive beam may refer to a distribution of signal strengths of the wireless signal received from the antenna in different spatial directions.

Further, the beam may be a wide beam, or a narrow beam, or other type of beam. The technique of forming the beam may be a beamforming technique or other technique. The beamforming technology may specifically be a digital beamforming technology, an analog beamforming technology, or a hybrid digital/analog beamforming technology.

The beam generally corresponds to the resource, for example, when the beam measurement is performed, the network device measures different beams through different resources, the terminal device feeds back the measured quality of the resource, and the network device knows the quality of the corresponding beam. In data transmission, the beam information is also indicated by its corresponding resource. For example, the network device indicates the information of the terminal device PDSCH beam through the resources in the TCI of the DCI.

Alternatively, a plurality of beams having the same or similar communication characteristics are regarded as one beam. One or more antenna ports may be included in a beam for transmitting data channels, control channels, sounding signals, and the like. The one or more antenna ports forming one beam may also be seen as one set of antenna ports.

In the embodiment of the present application, a beam refers to a transmission beam of a network device, unless otherwise specified. In beam measurement, each beam of the network device corresponds to one resource, so that the beam corresponding to the resource can be uniquely identified by the index of the resource.

2. Resource and index of resource

Channel resources: which may also be referred to as Channel Measurement Resource (CMR), refers to a measurement signal resource used for channel measurement.

The channel resources may include at least one of synchronization signal/physical broadcast channel block (SS/PBCH block) resources and non-zero power channel state information reference signal (NZP CSI-RS) resources. The SS/PBCH block may be referred to as a Synchronization Signal Block (SSB) for short.

It should be understood that the channel resource may also be other measurement signal resources, such as demodulation reference signal (DMRS) resources, cell specific reference signal (CS-RS) resources, UE specific reference signal (US-RS) resources, and other reference signal resources defined in existing protocols and in future protocols, which are not limited in this application.

Interference resources: which may also be referred to as Interference Measurement Resource (IMR), refers to a measurement signal resource used for interference measurement.

The interference resources may include at least one of channel state information interference measurement (CSI-IM) resources and NZP CSI-RS resources.

It should be understood that the interference resource may also be a reference signal resource in an existing protocol such as a DMRS resource, a CS-RS resource, or an US-RS, and other reference signal resources defined in a future protocol, which is not limited in this application.

A resource may be uniquely identified by an index of the resource. The index of a resource may also be referred to as an identification of the resource. For example, the identifier of the CSI-RS resource may be a CSI-RS resource identifier (CRI), the identifier of the SSB resource may be an SSB resource identifier (SSBRI), and the identifier of the Sounding Reference Signal (SRS) may be an SRS Resource Index (SRI).

In the prior art, a network device may send a measurement signal through different channel resources, a terminal device may report a portion of channel resources with a large reference signal received power to the network device through beam measurement, and the network device may select one or more corresponding beams of the portion of channel resources to perform data transmission. In the packet reporting mode, the terminal device reports two channel resources that can be received by the terminal device at the same time, and the network device simultaneously uses the beams corresponding to the two channel resources to perform data transmission on the terminal device.

However, in some scenarios, such as a multi-user multi-input multi-output (MU-MIMO) scenario, the network device may want to acquire more information about the two channel resources, so as to perform beam management more reasonably and improve the efficiency of multi-user transmission.

In view of this, the present application provides a measurement reporting method, by which a network device can obtain common interference information of multiple channel resources (i.e., multiple target channel resources) that can be simultaneously received and reported by a terminal device, so that based on the interference information, the network device can perform reasonable interference management, and improve efficiency of multi-user transmission. For example, the interference information may indicate an interference resource with a large interference degree to the multiple target channel resources, so that when the network device performs multi-user transmission, the interference resources reported by the terminal device may be avoided as much as possible. For another example, the interference information may indicate an interference resource with a smaller interference degree to the multiple target channel resources, so that when the network device performs multi-user transmission, the interference resources reported by the terminal device may be used as much as possible.

Fig. 2 is an exemplary flow chart of a measurement reporting method 200 provided herein. The method includes S210 to S240. The respective steps will be explained below. It should be understood that, in the method embodiments described below, only the network device and the terminal device are taken as examples of execution subjects, and the network device may also be replaced by a chip configured in the network device, and the terminal device may also be replaced by a chip configured in the terminal device.

S210, the network equipment sends the measurement configuration information to the terminal equipment. Accordingly, the terminal device receives the measurement configuration information sent by the network device.

Wherein the measurement configuration information may indicate N channel resources and M interference resources. For example, the measurement configuration information may include indexes of the N channel resources and indexes of the M channel resources. Wherein N is a positive integer greater than or equal to 2, and M is a positive integer greater than or equal to 1. The N channel resources and the M channel resources may be the same plurality of resources. For example, the network device configures multiple resources, and when the terminal device uses one of the resources as a channel resource, the other resources may be used as interference resources. The N channel resources and the M channel resources may also be different resources, and the application does not limit whether the N channel resources and the M channel resources are the same.

The measurement configuration information may also include other information related to measurement configuration, such as information about time domain transmission characteristics of the N channel resources and the M channel resources, and the number of ports used, and the like, which may specifically refer to the specification of the existing protocol and the future protocol, and is not described herein again. It should be understood that the transmission characteristics of a resource (e.g., channel resource and/or mutual interference resource) refer to whether the resource is transmitted periodically, non-continuously, or non-periodically.

Illustratively, the N channel resources and the M channel resources may be configured by a three-level structure (resource configuration-resource set-resource). That is, the network device may configure one or more resource configurations for the terminal device, each resource configuration comprising one or more resource sets, each resource set may comprise one or more channel resources and/or interference resources. Each resource allocation/resource set/resource includes an index of the resource allocation/resource set/resource. It should be understood that the present application does not limit the configuration manner of the information related to the measurement resource.

In a possible implementation manner, the measurement configuration information may further include related information reported by the measurement result. For example, the measurement configuration information may include one or more of: the method comprises the steps of reporting the number N of channel resources to be reported (N is more than or equal to 2 and less than or equal to N, and N is an integer), reporting the number M of interference resources to be reported (M is more than or equal to 1 and less than or equal to M, and M is an integer), the type of the interference resources to be reported, a calculation method of equivalent SINR (signal to interference plus noise ratio) or a reporting format of a measurement result. The reporting format of the measurement result may include a reporting arrangement of the interference resources and/or a reporting arrangement of the equivalent SINR, that is, what arrangement the interference resources are reported in, and what arrangement the equivalent SINR is reported in.

It should be noted that the above-mentioned related information reported with the measurement result may also be specified by a protocol or adopt a default value, which is not limited in this application.

Wherein, the type of the interference resource may be a strong interference resource or a weak interference resource.

The strong interference resource refers to a resource with strong interference to n target channel resources (that is, n channel resources reported by the terminal device), for example, an interference resource with a small corresponding equivalent SINR, and the index reporting the strong interference resource can notify the network device which beams corresponding to the resources will cause strong interference to beams corresponding to the n target channel resources, so that when multi-user transmission is performed, the target channel resources and the interference resources reported by the terminal device can be avoided as much as possible. For example, resource 3 is strong interference to resources 1 and 2, when the network device uses the beams corresponding to resources 1 and 2 to transmit data for terminal device 1, the beam corresponding to resource 3 may not be used simultaneously to transmit data for other users, otherwise, strong interference may be caused to terminal device 1.

The weak interference resource refers to a resource with weak interference to the n target channel resources, for example, an interference resource with a corresponding larger equivalent SINR. Reporting the index of the weak interference resource can inform the network device which beams corresponding to the resources cause little interference to the beams corresponding to the n target channel resources, and the target channel resources and the interference resources reported by the terminal device can be used simultaneously when multi-user transmission is carried out. For example, resource 3 is weak interference to resource 1 and resource 2, and when the network device uses the beam corresponding to resources 1 and 2 to transmit data for terminal device 1, the beam corresponding to resource 3 may be used to transmit data for other users, thereby improving transmission performance.

It should be understood that the measurement configuration information may also include other information related to reporting of the measurement result, for example, information such as reporting period, and the like, and specifically refer to the specification of the existing protocol or the future protocol.

S220, the network device sends a reference signal (or called a measurement signal) according to the measurement configuration information. Accordingly, the terminal device receives the reference signal according to the measurement configuration information.

Specifically, the network device may send the reference signal corresponding to each configured resource according to the measurement configuration information. And the terminal equipment receives corresponding reference signals on each resource configured by the network equipment according to the measurement configuration information.

For how the network device sends the reference signal according to the measurement configuration information and how the terminal device receives the reference signal according to the measurement configuration information, reference may be specifically made to the prior art, which is not described herein again.

S230, the terminal device determines n target channel resources that can be simultaneously received by the terminal device and interference information corresponding to the n target channel resources according to the measurement configuration information.

For example, the terminal device may obtain N Reference Signal Receiving Powers (RSRPs) by measuring reference signals respectively received on N channel resources, where N channel resources of the N channel resources that are simultaneously received by the terminal device and have the maximum corresponding N RSRPs may be determined as the N target channel resources, or the terminal device may determine N channel resources of the N channel resources that are simultaneously received by the terminal device and have the maximum corresponding N RSRPs greater than a preset threshold as the N target channel resources, or the terminal device may determine the N target channel resources in other manners. It should be understood that the present application is not limited to the specific manner in which the terminal device determines the n target channel resources.

For example, the interference information may include indexes of m interference resources and/or equivalent SINRs of the n target channel resources under interference of each of the m interference resources.

For example, the interference information may include an index of m interference resources, and/or an SINR of each of the n target channel resources under interference of each of the m interference resources.

In a possible implementation manner, the equivalent SINRs of the n target channel resources under the interference of any interference resource k in the m interference resources may be at least one of the following:

For example, suppose that the n target channel resources are channel resource 1 and channel resource 2, the m interference resources are interference resource 3 and interference resource 4, SINR1_ k represents SINR of channel resource 1 under interference of interference resource k, and similarly SINR2_ k represents SINR of channel resource 2 under interference of interference resource k. Then, the equivalent SINR of channel resource 1 and channel resource 2 under the interference of interfering resource 3 may be at least one of the following: SINR1_3+ SINR2_3, max (SINR1_3, SINR2_3), min (SINR1_3, SINR2_3), or avg (SINR1_3, SINR2_ 3). Accordingly, the equivalent SINR of channel resource 1 and channel resource 2 under interference of interfering resource 4 may be at least one of: SINR1_4+ SINR2_4, max (SINR1_4, SINR2_4), min (SINR1_4, SINR2_4), or avg (SINR1_4, SINR2_ 4). Where max (i, j) represents taking the maximum value of i and j, min (i, j) represents taking the minimum value of i and j, and avg (i, j) represents taking the average value of i and j.

The SINR sum or the average value may be calculated in dB, or may be calculated as a linear value. For example, SINR1_3 and SINR2_3 are 10dB and 20dB, respectively, and the corresponding linearity values are 10 and 100, respectively. If the calculation is performed in dB, the SINR1_3+ SINR2_3 is 30dB, and avg (SINR1_3, SINR2_3) is 15 dB. If the linear value is used for calculation, the SINR1_3+ SINR2_3 is 110, and avg (SINR1_3, SINR2_3) is 55 dB.

And S240, the terminal equipment reports the measurement result.

The measurement result may include indexes of the n target channel resources and interference information corresponding to the n target channel resources. Further, the measurement result may further include RSRPs corresponding to the n target channel resources, respectively.

In a possible implementation manner, in S230, the terminal device may determine the interference information corresponding to the n target channel resources by:

(1) the terminal device determines SINRs of the n target channel resources under the interference of each interference resource in the M channel resources.

For example, the n target channel resources are resource 1 and resource 2, and the M channel resources are resources 3 to 10. The terminal equipment can respectively calculate the SINR of the channel resource 1 under the interference of the interference resources 3-10, and similarly, calculate the SINR of the channel resource 2 under the interference of the interference resources 3-10.

(2) And the terminal equipment determines the equivalent SINR of the n target channel resources under the interference of each interference resource according to the SINR of the n target channel resources under each interference resource.

Specifically, for any interference resource r in the M channel resources, the terminal device may calculate equivalent SINRs of the n target channel resources under the interference of the interference resource r.

It should be understood that the SINR of the n target channel resources under the interference of the interference resource r refers to a plurality of SINRs calculated by using each target channel resource of the n target channel resources as a channel and using the interference resource r as interference. That is, for the interference resource r, there is one SINR for each target channel resource.

Illustratively, the equivalent SINR may be calculated by any one of the following methods, i.e., the equivalent SINR calculation method may be any one of the following methods. As described above, which equivalent SINR calculation method is specifically adopted may be configured by the measurement configuration information, or may be specified by a protocol. In the following, the n target channel resources are mainly taken as two resources (i.e., channel resource 1 and channel resource 2) as an example, but it should be understood that the application does not limit the number of the target channel resources. In the following description, the SINR of channel resource 1 under the interference of interference resource r is represented by SINR1_ r, and similarly, the SINR of channel resource 2 under the interference of interference resource r is represented by SINR2_ r.

A. Summation principle

That is, the equivalent SINR of the n target channel resources under the interference of the interference resource r is equal to the sum of the SINR of the n target channel resources under the interference of the M channel resources, respectively.

For example, the equivalent SINR of the n target channel resources under interference of interference resource 3 is equal to SINR1_3+ SINR2_3, and the equivalent SINR of the n target channel resources under interference of interference resource 4 is equal to SINR1_4+ SINR2_ 4. It can be understood that if (SINR1_3+ SINR2_3) > (SINR1_4+ SINR2_4), it means that interference resource 3 causes less interference to channel resources 1 and 2 than interference resource 4.

B. Principle of minimum

For example, the equivalent SINR of the n target channel resources under interference of interference resource 3 is equal to min (SINR1_3, SINR2_3), and the equivalent SINR of the n target channel resources under interference of interference resource 4 is equal to min (SINR1_4, SINR2_ 4). It can be understood that if min (SINR1_3, SINR2_3) > min (SINR1_4, SINR2_4), it means that interference resource 3 causes less interference to channel resources 1 and 2 than interference resource 4.

C. Principle of maximum value

For example, the equivalent SINR of the n target channel resources under interference of interference resource 3 is equal to max (SINR1_3, SINR2_3), and the equivalent SINR of the n target channel resources under interference of interference resource 4 is equal to max (SINR1_4, SINR2_ 4). It can be understood that if max (SINR1_3, SINR2_3) > max (SINR1_4, SINR2_4), it means that interference resource 3 causes less interference to channel resources 1 and 2 than interference resource 4.

D. Principle of mean value

For example, the equivalent SINR of the n target channel resources under interference of interference resource 3 may be equal to avg (SINR1_3, SINR2_3), and the equivalent SINR of the n target channel resources under interference of interference resource 4 may be equal to avg (SINR1_4, SINR2_ 4). It can be understood that avg (SINR1_3, SINR2_3) > avg (SINR1_4, SINR2_4) indicates that interference resource 3 causes less interference to channel resources 1 and 2 than interference resource 4.

It should be noted that, optionally, when determining the SINR of one channel resource under interference of one interference resource, the receiving beam of the receiving channel resource should be the same as the receiving beam of the receiving interference resource. And if the SINR is different, the terminal is considered to be incapable of measuring the corresponding SINR. For example, if the receiving beams of the two channel resources 1 and 2 are beam 1 and beam 2, and the receiving beam of the interference resource #3 is beam 1, the terminal device can only measure the SINR of channel resource 1 under the interference of interference resource 3, but cannot measure the SINR of channel resource 2 under the interference of interference resource 3. The receiving beam used for receiving a certain resource may be determined by the terminal device according to the measurement configuration information of the network device, or may be autonomously determined by the terminal device, which is not limited in this application.

If the terminal device cannot measure SINRi _ r of a certain channel resource i under the interference of the interference resource r, the SINRi _ r may not be considered when calculating the equivalent SINRs of the n target channel resources under the interference of the interference resource r. For example, for channel resources 1 and 2, the terminal device measures SINR1_3 of channel resource 1 under interference of interfering resource 3, but cannot measure SINR2_3 of channel resource 2 under interference of interfering resource 3. If the minimum rule is adopted, the equivalent SINR is the minimum value of all SINRs in { SINR1_3, SINR2_3} except SINR2_ 3. If the maximum value principle is adopted, the equivalent SINR is the maximum value of all SINRs in { SINR1_3, SINR2_3} except SINR2_ 3. If the average rule is adopted, the equivalent SINR is the average of all SINRs in { SINR1_3, SINR2_3} except SINR2_ 3.

(3) The terminal device may determine interference information corresponding to the n target channel resources according to the equivalent SINR of the n target channel resources under the interference of each interference resource.

For example, after determining the equivalent SINR of the n target channel resources under the interference of each interference resource in the M channel resources, the terminal device may determine the interference information corresponding to the n target channel resources by combining the type of the interference resource to be reported. Here, the interference information corresponding to the n target channel resources may include indexes of the m interference resources, and further may further include an equivalent SINR of the n target channel resources under interference of each of the m interference resources or an SINR of each of the n target channel resources under interference of each of the m interference resources. Or, if the network device can identify the interference resource to which the equivalent SINR reported by the terminal device or the SINR is, the terminal device may not report the indexes of the m interference resources.

Illustratively, the M interference resources are M interference resources corresponding to M equivalent SINRs with the largest (or smallest) equivalent SINRs among a plurality of equivalent SINRs corresponding to M channel resources. That is, the equivalent SINR of the n target channel resources under the interference of any one of the M interference resources is greater than (or less than) the equivalent SINR of the n target channel resources under the interference of any one of the M channel resources except the M interference resources.

For example, if the type of the interference resource configured by the network device and reported by the terminal device is a strong interference resource, the M interference resources are M interference resources corresponding to the M smallest equivalent SINRs among the M equivalent SINRs corresponding to the M channel resources. If the type of the interference resource configured by the network device and reported by the terminal device is a weak interference resource, the M interference resources are M interference resources corresponding to the maximum M equivalent SINRs among the M equivalent SINRs corresponding to the M channel resources.

For example, if the terminal device needs to report 3 interference resources with the strongest interference degree (i.e., M is 3), and the size relationship of the equivalent SINRs of the n target channel resources under the interference of each interference resource in the M channel resources is as follows: the equivalent SINR of the n target channel resources under the interference of the

interference resources

3, 4, and 5 is smaller than the equivalent SINR of the n target channel resources under the interference of other interference resources, and then the terminal device may report the

interference resources

3, 4, and 5. Further, the terminal device may also report equivalent SINRs corresponding to the

interference resources

3, 4, and 5, respectively, or the terminal device may report SINRs of the channel resources 1 and 2 under the interference of the

interference resources

3, 4, and 5, respectively, that is, each reported interference resource corresponds to two SINRs.

In a possible implementation manner, in S240, the terminal device may report the interference information corresponding to the n target channel resources according to an increasing or decreasing ranking order of the m equivalent SINRs corresponding to the m interference resources.

For example, the terminal device may report the indexes of the m interference resources according to an increasing or decreasing ranking order of the m equivalent SINRs corresponding to the m interference resources. Further, the terminal device may also report the equivalent SINRs corresponding to the m interference resources according to an increasing or decreasing ranking order of the m equivalent SINRs corresponding to the m interference resources, that is, report the equivalent SINRs of the n target channel resources under the interference of each interference resource in the m interference resources. Or, the terminal device may also report the SINR of each target channel resource in the n target channel resources under the interference of each interference resource in the m interference resources according to the ascending or descending ranking order of the m equivalent SINRs corresponding to the m interference resources. The index of the interference resource and the SINR (equivalent SINR or SINR of each target channel) corresponding to the interference resource may be arranged in a cross manner, that is, the index of each interference resource and the SINR corresponding to the interference resource are arranged together, or may not be arranged in a cross manner, that is, the indexes of all interference resources are arranged together and all SINRs are arranged together.

Fig. 3 and 4 respectively show schematic diagrams of a reporting format. It should be understood that fig. 3 and 4 are only described by taking two target channel resources (i.e., channel resource 1 and channel resource 2) and two interference resources (i.e., m is 2, and m interference resources are interference resource 3 and interference resource 4) as examples, and the number of reported channel resources and the number of interference resources are not limited in this application.

Referring to fig. 3 and fig. 4, the terminal device reports SINR of channel resources 1 and 2 under interference of interference resource 3, respectively, and SINR of channel resources 1 and 2 under interference of interference resource 3, respectively. It should be understood that the SINR of channel resources 1 and 2 under interference from interfering resource 3 may be replaced by the equivalent SINR of channel resources 1 and 2 under interference from interfering resource 3, and the SINR of channel resources 1 and 2 under interference from interfering resource 4 may be replaced by the equivalent SINR of channel resources 1 and 2 under interference from interfering resource 4. In fig. 3, the indexes of the interference resources and the SINRs corresponding to the interference resources are arranged in a cross manner, and in fig. 4, the indexes of the interference resources and the SINRs corresponding to the interference resources are not arranged in a cross manner.

Further, when reporting the SINR corresponding to the interference resource, for example, when reporting the equivalent SINR corresponding to the interference resource or the SINR of each target channel under interference of the interference resource, reporting may be performed by using a differential reporting criterion.

For example, if the equivalent SINR corresponding to the interference resource is to be reported, the equivalent SINR corresponding to different interference resources adopts a differential reporting criterion. Namely, the first equivalent SINR is reported by using x bits (bit), and the residual equivalent SINR is reported by using y (y < x) bits. x bits directly quantize the first equivalent SINR, and y bits quantize the difference value between each other equivalent SINR and the first equivalent SINR. The first equivalent SINR may be the largest equivalent SINR, the smallest equivalent SINR, or the first equivalent SINR. The values of x and y may be any value, for example, x-4 and y-2.

For example, fig. 5 shows a schematic diagram of a reporting format. It should be understood that fig. 5 only illustrates reporting two target channel resources (i.e., channel resource 1 and channel resource 2) and two interference resources (i.e., m is 2, and m interference resources are interference resource 3 and interference resource 4) as an example, and the number of reported channel resources and the number of interference resources are not limited in the present application. Referring to fig. 5, the first equivalent SINR is an equivalent SINR of channel resources 1 and 2 under interference of interference resource 3, and the equivalent SINR of channel resources 1 and 2 under interference of interference resource 3 is greater than the equivalent SINR of channel resources 1 and 2 under interference of interference resource 4. The second equivalent SINR is a difference between the first SINR and an equivalent SINR of channel resources 1 and 2 under interference of interference resource 4, and the equivalent SINR of channel resources 1 and 2 under interference of interference resource 4 is equal to the difference between the first equivalent SINR and the second equivalent SINR.

For another example, if the SINR of each target channel under interference of the interference resource needs to be reported, then a plurality of SINRs corresponding to the same interference resource are reported differentially. That is, the first SINR is reported by x bits, and the remaining SINRs are reported by y (y < x) bits. x bits directly quantize the first SINR, and y bits quantize the difference value of each other SINR and the first SINR. The first SINR may be the largest SINR of the two SINRs, may be the smallest SINR, or may be the first SINR. The values of x and y may be any value, for example, x-4 and y-2.

For example, fig. 6 shows a schematic diagram of a reporting format. It should be understood that fig. 6 is only described by taking two target channel resources (i.e., channel resource 1 and channel resource 2) and two interference resources (i.e., m is 2, and m interference resources are interference resource 3 and interference resource 4) as examples, and the number of reported channel resources and the number of interference resources are not limited in the present application. Referring to fig. 6, SINR of channel resources 1 and 2 under interference of interference resource 3 is reported in a differential manner, and SINR of channel resources 1 and 2 under interference of interference resource 4 is reported in a differential manner.

For another example, if the SINR of each target channel under interference of the interference resources is to be reported, the SINR of the same target channel under interference of different interference resources is reported differentially. The first SINR is reported by x bits, and the rest SINRs are reported by y (y < x) bits. x bits directly quantize the first SINR, and y bits quantize the difference value of each other SINR and the first SINR. The first SINR is an SINR ranked first in a reporting format.

For example, fig. 7 shows a schematic diagram of a reporting format. It should be understood that fig. 7 only illustrates reporting two target channel resources (i.e., channel resource 1 and channel resource 2) and two interference resources (i.e., m is 2, and m interference resources are interference resource 3 and interference resource 4) as an example, and the number of reported channel resources and the number of interference resources are not limited in the present application. Referring to fig. 7, SINR of channel resource 1 under interference of

interference resources

3 and 4 is reported in a differential manner, and SINR of channel resource 2 under interference of

interference resources

3 and 4 is reported in a differential manner.

The method provided by the present application is mainly described above by taking interference information as an equivalent SINR as an example. It should be noted that, in specific implementation, the SINR may be replaced by RSRQ or CQI or other parameters. Those skilled in the art will be able to determine the equivalent RSRQ and equivalent CQI from the prior art and the above description related to SINR.

In addition, it should be further noted that, in this embodiment, through one measurement configuration, the terminal device may determine n target channel resources that can be simultaneously received by the terminal device and interference information corresponding to the n target channel resources. In addition to this, the network device may also configure, through multiple measurement configurations, the terminal device to respectively report the n target channel resources that can be simultaneously received by the terminal device and the interference information corresponding to the n target channel resources. For example, through the first measurement configuration, the terminal device measures and reports the n target channel resources. Then, through the second measurement configuration, the terminal device further measures and reports the interference information corresponding to the n target channel resources determined in the previous step. In this embodiment, the n target channel resources and the interference information corresponding to the n target channel resources may be determined by the above-described method, and are not described herein again.
