For example, in NR, especially when the communication frequency band is in Frequency Range 2 (for example, above 6 GHz), since the high-frequency channel attenuates quickly, in order to ensure the coverage range, beam-based transmission and reception can be used.

In some embodiments of the present disclosure, in order to realize transmission of multiple transmission and reception points (Multi-Transmission Reception Point, M-TRP), multiple TRPs can send signals to a terminal device at the same time or the terminal device can send signals to multiple TRPs at the same time.

In some embodiments, the terminal device may feedback at least one group based on the measurement result of the physical layer reference signal receiving power (Layer 1 Reference Signal Receiving Power, L1-RSRP) of the reference signal corresponding to the reference signal resource, and the beams corresponding to the two reference signal resources in each group are beams that the terminal supports simultaneous reception and/or that the terminal supports simultaneous transmission. Optionally, the terminal device may report a group-based physical layer reference signal receiving power report (group based L1-RSRP report) and feedback the above-mentioned at least one group through the group-based L1-RSRP report.

It should be noted that the beam in the embodiments of the present disclosure may also be called beam, Quasi-Colocation (QCL) Type D, spatial setting, spatial filter, spatial relationship information (spatial relation info), spatial RX parameters, spatial Tx parameter, Transmission Configuration Indication (TCI) state, etc., and the embodiments of the present disclosure are not limited to this.

In some embodiments, the terminal device may report the L1-RSRP corresponding to the reference signal resources in each group. However, if the difference in L1-RSRP between the two beams is very large, the probability of actually using the beam with a smaller absolute value of L1-RSRP is very small. In addition, if the two beams are transmitted at the same time, they may interfere with each other. For example, when the two beams are used in a non-TDM (Time Division Multiplexing) manner, that is, when the two beams are used in FDM (Frequency Division Multiplexing) or SDM (Space Division Multiplexing), the two beams may interfere with each other when transmitted simultaneously.

FIG2A is an interactive schematic diagram of a measurement method according to an embodiment of the present disclosure. The method may be performed by the above communication system. As shown in FIG2A , the method may include:

Step S2101: The network device sends fifth information to the terminal device.

In some embodiments, the terminal device may receive the fifth information. For example, the terminal device may receive the fifth information sent by the network device.

In some embodiments, the fifth information can be used to configure multiple reference signal resources, and the multiple reference signal resources are used for the terminal to measure, and determine at least one reference signal resource group for reporting. A reference signal resource group may include reference signal resource identifiers of multiple reference signal resources, and one reference signal resource corresponds to at least one beam, and the beams corresponding to the multiple reference signal resources are beams supported by the terminal device for receiving and/or sending. Exemplarily, the beams corresponding to the multiple reference signal resources are beams supported by the terminal device for simultaneous reception and/or transmission. For example, the terminal device can simultaneously receive, simultaneously transmit, or simultaneously receive and transmit through multiple beams. Among them, the terminal supports simultaneous reception and/or transmission, including terminals based on the same or different spatial filters.

In some embodiments, the network device may send a fifth message, and the fifth message may include the fifth information. For example, the network device may send the fifth message to the terminal device. Optionally, the terminal device may receive the fifth message.

The fifth message may include at least one of a radio resource control RRC (Radio Resource Control) message, a media access control control element MAC CE (Medium Access Control Control Element), downlink control information DCI (Downlink Control Information) or other messages sent by the network device to the terminal device.

In some embodiments, step S2101 can be omitted, and the terminal device can autonomously implement the function indicated by the fifth information, or the above function is default or by default.

Step S2102: The terminal device sends fourth information to the network device.

In some embodiments, the network device may receive the fourth information. For example, the network device may receive the fourth information sent by the terminal device.

In some embodiments, the fourth information can be used to determine the above-mentioned at least one reference signal resource group, a reference signal resource group may include reference signal resource identifiers of multiple reference signal resources, one reference signal resource corresponds to at least one beam, and the beams corresponding to multiple reference signal resources can be used for simultaneous reception and/or transmission.

In some embodiments, the fourth information may also include L1-RSRP corresponding to each reference signal resource in at least one reference signal resource group.

In some embodiments, the fourth information may be used to determine a beam supporting reception and/or transmission.

In some embodiments, the fourth information may be used to determine a beam supporting simultaneous reception and/or transmission.

In some embodiments, the fourth information may be used to determine at least two reference signal resources that can form a group, that is, to determine which two reference signal resources can form a group.

In some embodiments, the fourth information may be used to determine at least two reference signal resources that can be paired, that is, to determine which two reference signal resources can be paired.

In some embodiments, the fourth information may be a newly defined report.

In some embodiments, the name of the fourth information is not limited, for example, it can be "measurement report", "measurement information", etc.

In some embodiments, the fourth information may include reference signal resource identifiers (IDs) corresponding to at least two reference signal resources, respectively, and the at least two reference signal resources correspond to beams that the terminal device supports simultaneous reception and/or transmission.

In some embodiments, the terminal device may send a fourth message, and the fourth message may include the fourth information. For example, the terminal device may send the fourth message to the network device. Optionally, the network device may receive the fourth message.

The fourth message may include at least one of an RRC message, a MAC CE, uplink control information UCI (Uplink Control Information) or other messages sent by the terminal device to the network device.

In some embodiments, step S2102 may be omitted, and the content indicated by the fourth information is default or default.

Step S2103: The network device sends first information to the terminal device.

In some embodiments, the terminal device may receive the first information. For example, the terminal device may receive the first information sent by the network device.

In some embodiments, the first information may be used to configure multiple reference signal resources, and the multiple reference signal resources may be used by the terminal device to perform measurement and obtain measurement data. It should be noted that the multiple may be at least two.

For example, the terminal device may perform beam measurement based on at least two reference signal resources to obtain measurement data. The measurement data may be at least one of L1-RSRP and L1-SINR.

In some embodiments, the first information may be used to configure one or more reference signal resources, and the one or more reference signal resources may be used by the terminal device to perform measurements and obtain measurement data.

Optionally, the first information may also include resources used for interference measurement. In this way, the resources used for interference measurement may be acquired from the first information.

Optionally, the first information may further include the fifth information, or the first information may implement the function of the fifth information. For example, the first information may instruct the terminal device to report a beam that supports simultaneous reception and/or transmission. For another example, the first information may configure a measurement configuration for the terminal device, and the measurement configuration may be used to instruct the terminal device to report a beam that supports simultaneous reception and/or transmission. In this way, the first information may be used to instruct the terminal device to report a beam that supports simultaneous reception and/or transmission, or other separate information (such as the fifth information) may be used to instruct the terminal device to report a beam that supports simultaneous reception and/or transmission.

In some embodiments, the measurement data may include at least one of the following:

Physical layer reference signal received power (L1-RSRP);

Physical layer signal-to-interference-to-noise ratio (L1-SINR);

Physical layer reference signal receiving quality (Layer 1 Reference Signal Receiving Quality, L1-RSRQ).

In some embodiments, the above-mentioned multiple reference signal resources may belong to the same reference signal resource group.

In one implementation, the multiple reference signal resources in the first information belong to the same reference signal resource group, and the multiple reference signal resources within the same reference signal resource group may be reference signal resources that the terminal can support simultaneous reception and/or simultaneous transmission, such as the reference signal resource group that can support simultaneous reception and/or simultaneous transmission reported by the terminal in the fourth information; or the multiple reference signal resources within the same reference signal resource group are reference signal resources that the terminal cannot support simultaneous reception and/or simultaneous transmission, such as one reference signal resource group corresponds to one reference signal resource set, and one reference signal resource set corresponds to one TRP of the network device.

In one implementation, when multiple reference signal resources may belong to the same reference signal resource group, one reference signal resource group may correspond to one resource for interference measurement. That is, the same reference signal resource group shares one resource for interference measurement.

In one implementation, when multiple reference signal resources may belong to the same reference signal resource group, one reference signal resource in the reference signal resource group may correspond to one resource for interference measurement. For example, in the same reference signal resource group, different reference signal resources may correspond to different resources for interference measurement.

For example, the interference information obtained through the resource measurement may include interference from the first signal, the first signal does not include the beam corresponding to the reference signal resource in the reference signal resource group, and may include a beam or signal other than the beam corresponding to the reference signal resource in the reference signal resource group. In other words, the interference information obtained through the resource measurement includes interference other than the beam corresponding to the reference signal resource in the reference signal resource group.

In some other embodiments, the above-mentioned multiple reference signal resources may belong to different reference signal resource groups.

Optionally, when multiple reference signal resources belong to different reference signal resource groups, one reference signal resource may correspond to at least one resource for interference measurement. The resources for interference measurement corresponding to different reference signal resources may be different or the same.

In some embodiments, the reference signal resources included in different reference signal resource groups are not completely the same. For example, the reference signal resources in different reference signal resource groups may include at least one different reference signal resource.

In one implementation, the two reference signal resource groups may include completely different reference signal resources. For example, the first reference signal resource group includes a first reference signal resource and a second reference signal resource, and the second reference signal resource group may include a third reference signal resource and a fourth reference signal resource.

In one implementation, the two reference signal resource groups may include some of the same reference signal resources. For example, the first reference signal resource group includes the first reference signal resource and the second reference signal resource, and the second reference signal resource group may include the first reference signal resource and the third reference signal resource.

In some embodiments, the network device may send a first message, and the first message may include the first information. For example, the network device may send the first message to the terminal device. Optionally, the terminal device may receive the first message.

The first message may include at least one of an RRC message, a MAC CE, a DCI, or other messages sent by a network device to a terminal device.

In some embodiments, step S2103 can be omitted, and the terminal device can autonomously implement the function indicated by the first information, or the above function is default or by default.

Step S2104: The network device sends second information to the terminal device.

In some embodiments, the terminal device may receive the second information. For example, the terminal device may receive the second information sent by the network device.

In some embodiments, the second information may configure resources used for interference measurement. The resources used for interference measurement may be reference signal resources used for interference measurement, or may be other wireless resources used for interference measurement.

In some embodiments, the name of the second information is not limited, and may be, for example, "measurement configuration", "configuration information", "interference measurement configuration information", etc.

Optionally, when the first information includes resources used for interference measurement, the second information may not need to be sent.

Optionally, the terminal device may perform measurement based on the resources used for interference measurement to obtain interference information, and the interference information may be interference in a physical layer signal to interference plus noise ratio (Layer 1 Signal to Interference plus Noise Ratio, L1-SINR).

In some embodiments, the resource for interference measurement may include at least one of the following:

Interference Measurement Resource (IMR);

Non-Zero-Power Channel State Information Reference Signal (NZP CSI-RS) resources.

In one implementation, the IMR may be a zero-power channel state information reference signal (ZP CSI-RS) resource.

In some embodiments, a reference signal resource group corresponds to a resource for interference measurement. For example, the interference information obtained by the resource measurement may include interference from a first signal, and the first signal does not include a beam corresponding to a reference signal resource in the reference signal resource group, and may include a beam or signal other than the beam corresponding to the reference signal resource in the reference signal resource group. In other words, the interference information obtained by the resource measurement includes interference other than the beam corresponding to the reference signal resource in the reference signal resource group.

In some other embodiments, a reference signal resource of a reference signal resource group corresponds to a resource for interference measurement. For example, the interference information obtained by measuring the resource may include interference from a second signal, the second signal including interference other than the beam corresponding to the specific reference signal resource, but not including the beam corresponding to the specific reference signal resource, the specific reference signal resource being the reference signal resource corresponding to the resource. That is, the interference information obtained by measuring the resource may include interference other than the beam corresponding to the reference signal resource, that is, may include interference from beams corresponding to other reference signal resources in the reference signal resource group.

In some embodiments, step S2104 can be omitted, and the terminal device can autonomously implement the function indicated by the second information, or the above function is default or by default.

In some embodiments, when the measurement data of the terminal device includes L1-SINR, the network device may send the second information, and the terminal device may also obtain resources for interference measurement. Conversely, when the measurement data does not include L1-SINR (for example, only includes L1-RSRP), the terminal device does not need to obtain resources for interference measurement, and the network device may not need to send the second information.

Step S2105: The terminal device obtains measurement data.

In some embodiments, the terminal device may perform measurements and obtain measurement data.

In one implementation, the terminal device may perform measurements based on the multiple reference signal resources to obtain measurement data. For example, the terminal device may perform beam measurements on beams corresponding to the multiple reference signal resources to obtain at least one of L1-RSRP, L1-SINR, and L1-RSRQ.

Step S2106: The terminal device sends third information to the network device.

In some embodiments, the network device may receive the third information. For example, the network device may receive the third information sent by the terminal device.

In some embodiments, the third information may be used to report measurement data. The measurement data may include at least one of L1-RSRP, L1-SINR, and L1-RSRQ.

In some embodiments, the name of the third information is not limited, for example, it can be "measurement report", "group-based measurement report", "group-based L1-RSRP report (group based L1-RSRP)", "group-based L1-SINR report (L1-SINR beam report)", "group-based L1-RSRQ report (L1-RSRQ beam report)", etc.

In some embodiments, the third information may be newly defined information or a report.

In some embodiments, the third information may also include the fourth information, or the third information may implement the function of the fourth information. For example, the third information may also be used to determine a beam that supports simultaneous reception and/or transmission.

In some embodiments, the third information may include report information corresponding to at least one beam group. A beam group may include one or more beams. The beam corresponding to the reference signal resource in a beam group is a beam that the terminal can support simultaneous reception and/or simultaneous transmission.

In one implementation, the report information may include at least one of the following:

Reference signal resource group identifier;

reference signal resource identifiers corresponding to at least two reference signal resources respectively;

Measurement data corresponding to at least two reference signal resources respectively (e.g., L1-RSRP, L1-SINR, L1-RSRQ);

Indication information, the indication information is used to indicate that the terminal device supports the use of at least two beams to simultaneously receive and/or transmit, and the at least two beams are beams corresponding to at least two reference signal resources in a beam group.

Optionally, the at least two reference signal resources may belong to the same reference signal resource group, or may belong to different reference signal resource groups.

In some embodiments, a reference signal resource group may include two reference signal resources, and a beam group may include two reference signal resources corresponding to a reference signal resource group. In this way, the above report information may only include the reference signal resource group identifier and the measurement data corresponding to at least two reference signal resources, without reporting the reference signal resource identifier.

In some embodiments, the terminal device is only configured with two reference signal resources, and the report information may only include measurement data corresponding to the two reference signal resources respectively.

In some embodiments, the at least two reference signal resources configured by the terminal device belong to the same reference signal resource group identifier, and the report information may only include the reference signal resource identifiers corresponding to the at least two reference signal resources respectively, and the measurement data corresponding to the at least two reference signal resources respectively.

In some embodiments, at least two reference signal resources configured by the terminal device belong to different reference signal resource group identifiers, and the report information may include the reference signal resource identifier, the reference signal resource group identifier, and measurement data corresponding to the reference signal resources respectively.

In some embodiments, the above indication information is an optional field. For example, the report information may not include the above indication information, and the default terminal device supports the use of at least two beams to simultaneously receive and/or transmit, and the at least two beams are beams corresponding to at least two reference signal resources in a beam group.

In some embodiments, the report information may only include the above-mentioned indication information.

In some embodiments, the report information satisfies at least one of the following conditions:

The value of the measurement data corresponding to the first reference signal resource is an absolute value, and the values of the measurement data corresponding to other reference signal resources except the first reference signal resource are relative values, where the relative value is a difference between the measurement data corresponding to other reference signal resources and the measurement data corresponding to the first reference signal resource, and the measurement data corresponding to the first reference signal resource is the reference signal resource with the largest measurement data among the multiple reference signal resources included in the report information;

The measurement data corresponding to the reference signal resource is greater than or equal to the first threshold value. For example, the measurement data corresponding to each reference signal resource in the report information is greater than or equal to the first threshold value;

The report information corresponding to a beam group includes multiple reference signal resources, and the difference between the measurement data corresponding to any two reference signal resources in a beam group is less than or equal to a first difference threshold. For example, the difference between the measurement data corresponding to any two reference signal resources in a beam group is less than or equal to the first difference threshold.

In some embodiments, the report information may further include a first identifier. The first identifier may be used to indicate the first reference signal resource identifier and/or a reference signal resource group identifier corresponding to the first reference signal resource.

Optionally, the first identifier may be used to indicate the first reference signal resource, that is, to indicate a reference signal resource with the largest measurement data.

For example, the first identifier may include a first reference signal resource identifier, and the first reference signal resource identifier is an identifier of a first reference signal resource.

For another example, the first identifier may include a reference signal resource group identifier corresponding to the first reference signal resource. For example, if the reference signal resource group includes only one first reference signal resource, the first reference signal resource identifier may not be required.

For another example, the first identifier may include the above-mentioned first reference signal resource identifier and a reference signal resource group identifier.

In some embodiments, if the smaller measurement data in the beam group is less than the first threshold value, the report information of the beam group may only include report information corresponding to one reference signal resource. For example, the report information of the beam group may only include a reference signal resource identifier and measurement data corresponding to one reference signal resource.

In some embodiments, if the difference in measurement data corresponding to any two reference signal resources in a beam group is greater than a first difference threshold, the report information of the beam group may only include report information corresponding to one reference signal resource. For example, the report information of the beam group may only include the reference signal resource identifier and measurement data corresponding to the reference signal resource with the largest measurement data.

In one implementation, the first threshold value may be a value configured by the terminal device, a value configured by the network device and sent to the terminal device, or a value determined according to a protocol, which is not limited in the embodiments of the present disclosure.

In one implementation, the first difference threshold may be a value configured by the terminal device, a value configured by the network device and sent to the terminal device, or a value determined according to a protocol, and this disclosure embodiment is not limited thereto.

In some embodiments, at least one beam group in the above-mentioned third information may include a first beam group, and the first beam group may include a first beam and a second beam, the first beam corresponds to a first reference signal resource, and the second beam corresponds to a second reference signal resource, the first reference signal resource is a reference signal resource with the largest measurement data among multiple reference signal resources measured and reported by the terminal, and the second reference signal resource is a reference signal resource with the largest measurement data among at least one third reference signal resource, and the third reference signal resource is a reference signal resource among multiple reference signal resources measured and reported by the terminal that can be received and/or sent simultaneously with the first reference signal resource.

In some other embodiments, at least one beam group in the above-mentioned third information may include the above-mentioned first beam group and second beam group, the second beam group may include a fourth beam and a fifth beam, the fourth beam corresponds to a fourth reference signal resource, the fifth beam corresponds to a fifth reference signal resource, the fourth reference signal resource is a reference signal resource with the largest measurement data among multiple reference signal resources measured and reported by the terminal, excluding the first reference signal resource and the second reference signal resource, the fifth reference signal resource is a reference signal resource with the largest measurement data among at least one sixth reference signal resource, and the sixth reference signal resource is a reference signal resource among multiple reference signal resources measured and reported by the terminal, excluding the first reference signal resource and the second reference signal resource.

By analogy, at least one beam group in the third information may include a first beam group, a second beam group, a third beam group, ..., an Nth beam group. Among them, a beam group may include two beams (referred to as a first beam and a second beam), and the reference signal resource corresponding to the first beam of the Nth beam group is a reference signal resource with the largest measurement data among multiple reference signal resources measured and reported by the terminal, excluding reference signal resources in the first N-1 beam groups. For example, the reference signal resource corresponding to the first beam of the first beam group is a reference signal resource with the largest measurement data, and the reference signal resource corresponding to the third beam group is a reference signal resource with the largest measurement data excluding reference signal resources in the first and second beam groups. The second beam in each beam group can be received and/or transmitted simultaneously with the first beam, and the measurement data of the reference signal resource corresponding to the second beam is the maximum value of the measurement data among the reference signal resources corresponding to at least one beam that can be received and/or transmitted simultaneously with the first beam, excluding reference signal resources in the N-1 beam groups.

In some embodiments, the terminal device may send a third message, and the third message may include the third information. For example, the terminal device may send the third message to the network device. Optionally, the network device may receive the third message.

The third message may include at least one of an RRC message, a MAC CE, a UCI, or other messages sent by the terminal device to the network device.

By adopting the above method, the resources used for terminal device measurement can be flexibly configured, thereby improving the effectiveness and accuracy of measurement reporting information.

The method involved in the embodiment of the present disclosure may include at least one of the above steps S2101 to S2106. For example, step S2103 can be implemented as an independent embodiment, step S2106 can be implemented as an independent embodiment, step S2103+S2105 can be implemented as an independent embodiment, step S2103+S2106 can be implemented as an independent embodiment, step S2103+S2105+S2106 can be implemented as an independent embodiment, step S2103+S2104 can be implemented as an independent embodiment, step S2103+S2104+S2106 can be implemented as an independent embodiment, step S2101+S2103 can be implemented as an independent embodiment, step S2103+S2104+S2106 can be implemented as an independent embodiment. 101+S2103+S2106 can be implemented as an independent embodiment, step S2101+S2102+S2103 can be implemented as an independent embodiment, step S2101+S2102+S2103+S2106 can be implemented as an independent embodiment, step S2101+S2103+S2104 can be implemented as an independent embodiment, step S2101+S2103+S2104+S2106 can be implemented as an independent embodiment, but S2101+S2102+S2103+S2104+S2106 can be implemented as an independent embodiment, but is not limited to this.

For example, in step S2101, the network device sends the fifth information to the terminal device, and the fifth information configures multiple reference signal resources, and configures the terminal device to report the reference signal resource group that supports simultaneous reception. In step S2102, the terminal device can determine at least one reference signal resource group that supports simultaneous reception based on the reference signal resources configured by the fifth information, and report it to the network device through the fourth information. For example, the reference signal resource group may include resource A and resource B. In step S2103, the network device determines resource A and resource B, and sends the reference signal and interference measurement resource corresponding to resource A and resource B through the first information, indicating that the terminal reports the L1-SINR when resource A and resource B are a beam group, that is, reports the L1-SINR when the beams corresponding to resource A and resource B are simultaneously received and/or simultaneously sent. Optionally, the network device may not send the interference measurement resource in step S2103, but send the interference measurement resource in step S2104.

For another example, in step S2101, the network device sends the fifth information to the terminal device, and the fifth information configures multiple reference signal resources, and configures the terminal device to report the reference signal resource group that supports simultaneous reception. In step S2102, the terminal device can determine at least one reference signal resource group that supports simultaneous reception based on the reference signal resources configured by the fifth information and report it to the network device through the fourth information. The reference signal resource group includes resources A and resources B, and the L1-RSRP corresponding to resources A and B respectively. In step S2103, the network device determines resources A and resources B, and configures resources A and resources B and interference measurement resources through the first information, and instructs the terminal to report the L1-SINR when resources A and resources B are a beam group, that is, to report the L1-SINR when the beams corresponding to resources A and resources B are simultaneously received and/or sent simultaneously.

For another example, in step S2103, the network device sends first information to the terminal device, where the first information configures multiple reference signal resources, and the multiple reference signal resources include at least one reference signal resource group, and each reference signal resource group is a beam group that the terminal device can support simultaneous reception and/or simultaneous transmission. In step S2105, the terminal device determines the L1-SINR corresponding to the reference signal resource identifier contained in the beam group corresponding to the reference signal resource group based on the at least one reference signal resource group configured by the first information, and in step S2106, the terminal device can report the L1-SINR based on the third information.

For another example, in step S2103, the network device sends first information to the terminal device, where the first information configures multiple reference signal resources, the multiple reference signal resources include two reference signal resource sets, and different reference signal resource sets correspond to different TRPs. In step S2106, the terminal device determines the beam groups that can be simultaneously received and/or simultaneously transmitted by at least one terminal device based on the multiple reference signal resources configured by the first information, and reports the reference signal resource identifiers contained in the beam groups and the corresponding L1-SINRs.

In some embodiments, the above steps S2101 to S2106 can be executed in a swapped order or simultaneously. For example, S2103 and S2104 can be executed in a swapped order or simultaneously.

In some embodiments, the above steps S2101 to S2106 are all optional steps.

In some embodiments, reference may be made to other optional implementations described before or after the specification corresponding to FIG. 2A .

FIG2B is an interactive schematic diagram of a measurement method according to an embodiment of the present disclosure. As shown in FIG2B , an embodiment of the present disclosure relates to a measurement method, which may be performed by a communication system, and the method may include:

Step S2201: The network device sends first information to the terminal device.

The optional implementation of step S2201 can refer to the optional implementation of step S2103 in FIG. 2A and other related parts in the embodiment involved in FIG. 2A , which will not be described in detail here.

Optionally, the above beam supports simultaneous reception, supports simultaneous transmission, or supports simultaneous reception and transmission, which can be indicated by the network device, that is, instructing the terminal device to report which group, or can also be reported by the terminal device in a beam report.

In one implementation, the reference signal resources of different reference signal resource groups include at least one different reference signal resource.

In one implementation, each reference signal resource group corresponds to a reference signal resource for interference measurement, wherein the interference corresponds to a reference signal resource for interference measurement, that is, the interference includes interference outside the beam corresponding to the reference signal resource in this reference signal resource group.

In one implementation, each reference signal resource in each reference signal resource group may correspond to a reference signal resource for interference measurement. Optionally, interference measurement is required only for situations where L1-SINR needs to be measured, and L1-RSRP does not need interference measurement. Among them, the reference signal resources corresponding to different interference measurements respectively may include interference other than the beam corresponding to the reference signal resource, that is, it may include interference of beams corresponding to other reference signal resources in the reference signal resource group.

Optionally, the reference signal resource for interference measurement may include an IMR (interference measurement resource), for example, a ZP CSI-RS. The reference signal resource for interference measurement may also include an NZP CSI-RS resource for interference measurement.

In some embodiments, the terminal device may report third information, which may include at least one of group based L1-RSRP beam report and group based L1-SINR beam report.

In some embodiments, the third information (group based L1-RSRP/L1-SINR beam report) reported by the terminal device includes at least one beam group, and the information of each beam group includes at least one of the following: a reference signal resource ID corresponding to the reference signal resource, a reference signal resource group ID, and measurement data corresponding to each reference signal resource ID (for example, at least one of L1-RSRP and L1-SINR).

In one implementation, the reference signal resources included in each beam group are from the same reference signal resource group.

Optionally, if each reference signal resource group contains two reference signal resources, and the beam group also contains two reference signal resources corresponding to the reference signal resource group, then it is only necessary to report the reference signal resource group ID and the L1-RSRP/L1-SINR corresponding to each reference signal resource, and there is no need to report the reference signal resource ID.

In some embodiments of the present disclosure, the two reference signal resources belong to different reference signal resource groups, which may also be referred to as a reference signal resource subset, a reference signal resource set, or a reference signal resource pair.

In one implementation, each reference signal resource may correspond to a reference signal resource used for interference measurement.

In one implementation, the third information (group based L1-RSRP/L1-SINR beam report) reported by the terminal device may include at least one beam group, and the information of each beam group includes at least one of the following: a reference signal resource ID corresponding to the reference signal resource, a reference signal resource group ID, and measurement data corresponding to each reference signal resource ID (for example, at least one of L1-RSRP and L1-SINR).

In one implementation, the reference signal resources included in each beam group come from different reference signal resource groups.

In some embodiments, the reference signal resource used for interference measurement may be configured through the first information, or configured based on other information (eg, the second information).

In some embodiments, the third information may satisfy at least one of the following conditions:

The value of the maximum measurement data (such as L1-RSRP or L1-SINR) in all beam groups reports its absolute value, and other measurement data reports the relative value between the maximum measurement data value and the maximum measurement data value. Optionally, the third information may need to indicate a reference signal resource identifier (ID) or a group identifier (ID) corresponding to the maximum measurement data value;

In each beam group, the smaller measurement data is greater than or equal to the first threshold value. Otherwise, the beam group only contains beam group information corresponding to one reference signal resource;

In each beam group, the difference between two measurement data must be less than or equal to the first difference. Otherwise, the beam group only includes beam group information corresponding to one reference signal resource.

In some embodiments, at least one beam group in the third information may include a first beam group, the first beam group includes a first reference signal resource with the largest measurement data among all fed-back beam groups, and the second reference signal resource in the first beam group is: one with the largest measurement data among multiple reference signal resources that can be received and/or sent simultaneously with the first reference signal resource;

Optionally, at least one of the beam groups in the third information may also be a third reference signal resource corresponding to the larger measurement data contained in the second beam group, and its measurement data should be the largest measurement data (which may be larger or smaller than the second reference signal resource) among all the beam groups fed back except the measurement data of the first reference signal resource. Similarly, the fourth reference signal resource in the second beam group should be the largest one among the multiple reference signal resources that can be received and/or sent simultaneously with the third reference signal resource except the first and second reference signal resources.

Likewise, optionally, other beam groups included in the at least one beam group in the third information may be similarly included.

In some embodiments, when two reference signal resources correspond to the same reference signal resource group, the network device determines that the two reference signal resources correspond to beams that the terminal device can support simultaneous reception and/or simultaneous transmission, which may include at least one of the following:

Method 1: Determined based on the third information reported by the terminal device (group based L1-RSRP beam report).

Method 2: Based on a newly defined report (such as the fourth information) of the terminal device, the report may only report which two reference signal resources may be a group or a pair. The terminal device may obtain based on the output of the AI model.

For example, the terminal device may report at least two reference signal resource IDs, where the two reference signal resource IDs correspond to beams that the terminal device supports simultaneous reception and/or simultaneous transmission.

Accordingly, the network device needs to configure the measurement configuration, which can instruct the terminal device to report beams that support simultaneous reception, or beams that support simultaneous transmission, or beams that support simultaneous reception and transmission.

By adopting the above method, group based L1-RSRP beam report or group based L1-SINR beam report can be implemented, which can improve the effectiveness and accuracy of beam reporting information in multi-TRP scenarios.
