Description

Methods and apparatus for configuring reference signals, and communication systems Technical Field

[0001] The embodiments of this application relate to the field of communication technology. Background Technology

[0002] In the new Radio Release 14 (NR Rel-14), artificial intelligence or machine learning (AI / ML) for the air interface was investigated. AI / ML can be used for the following use cases: Channel State Information (CSI) feedback enhancement, beam management, and positioning enhancement. CSI feedback enhancement can include CSI prediction and CSI compression; beam management can include spatial domain beam prediction (i.e., BM case-1) and temporal beam prediction (i.e., BM case-2); positioning enhancement can include direct positioning and AI / ML-assisted positioning.

[0003] The network device can configure a set of beams (i.e., reference signals) (e.g., set B) for measurement by the terminal device, and the measurement (i.e., measurement result) for set B is used as input to the AI / ML function / model. The network device can also configure a set of beams (i.e., reference signals) (e.g., set A) for prediction by the terminal device, for example, set A can be used for inference operations.

[0004] In some sub-use cases, a two-sided model can be used, meaning the AI / ML function or model resides on both the terminal device side and the network device side. In other sub-use cases, a one-sided model can be used, meaning the AI / ML function or model resides either on the terminal device side or on the network device side. For beam management, the AI / ML model can reside on both the terminal device side and / or on the network device side.

[0005] In CSI prediction, AI / ML functions or models can be configured on the terminal device side. The terminal device can measure the reference signal on one or more time instances in the observation window and predict the CSI on one or more time instances in the future prediction window.

[0006] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this application and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this application. Summary of the Invention

[0007] In version 19 (Rel-19), for AI / ML functions or models set on the terminal device side, it has been agreed that for inference operations, separate resource sets will be configured for set A and set B, and set A will not be measured by the terminal device. Furthermore, set A and set B are configured with different resource settings; for example, different resource settings could be different CSI ResoluceConfig IDs, as shown in Table 1 below.

[0008] Table 1

[0009] In the prior art, in any slot, the number of active Channel State Information Reference Signal Resources (CSI-RS resources) or active CSI-RS ports in the active bandwidth portion (active BWP) of the terminal device will not exceed the reporting capacity. Non-zero power (NZP) CSI-RS resources are active for the duration defined in Table 2 below.

[0010] Table 2

[0011] If a CSI-RS resource is referenced N times by one or more CSI report settings, then the CSI-RS resource and the CSI-RS ports within the CSI-RS resource are counted N times.

[0012] The inventors of this application have discovered that, for beam management based on AI / ML functions or models, since the terminal device does not measure the set A used for inference, it is necessary to clarify that the channel state information reference signal resources (CSI-RS resources) in the set A used for inference are not counted as active resources or active ports; in addition, how to indicate the set A used for inference and / or the resource settings of set A is also an issue that needs to be clarified.

[0013] To address at least one of the aforementioned problems, embodiments of this application provide a method, apparatus, and communication system for configuring reference signals. In this method, for inference operations of an artificial intelligence model or function, channel state information reference signal resources (CSI-RS resources) in a first set of reference signals are not counted as activated resources or activated ports. Thus, a clear processing method is available for counting activated resources or activated ports related to set A during inference operations.

[0014] According to one aspect of the embodiments of this application, an apparatus for configuring reference signals is provided, applied to a terminal device, wherein at least one of the terminal device and a network device is configured with an artificial intelligence model or function for beam management, the apparatus comprising:

[0015] A first receiver is configured with a first reference signal set (Set A) and a second reference signal set (Set B), respectively.

[0016] The resource settings of the first reference signal set and the resource settings of the second reference signal set are configured using different Channel State Information Resource Configuration Identifiers (CSI-ResourceConfigId).

[0017] For the reasoning operation of the artificial intelligence model or function, the channel state information reference signal resources (CSI-RS resources) in the first reference signal set are not counted as active resources or active ports.

[0018] According to another aspect of the embodiments of this application, an apparatus for configuring reference signals is provided, applied to a network device, wherein at least one of the network device and a terminal device is configured with an artificial intelligence model or function for beam management, the apparatus comprising:

[0019] A first transmitter configures a first reference signal set (Set A) and a second reference signal set (Set B) to the terminal device, wherein the resource settings of the first reference signal set and the resource settings of the second reference signal set are configured using different Channel State Information Resource Configuration Ids (CSI-ResourceConfigId).

[0020] For the reasoning operation of the artificial intelligence model or function, the channel state information reference signal resources (CSI-RS resources) in the first reference signal set are not counted as active resources or active ports.

[0021] One of the beneficial effects of this application embodiment is that, for the inference operation of an artificial intelligence model or function, the channel state information reference signal resources (CSI-RS resources) in the first reference signal set are not counted as active resources or active ports. Thus, there is a clear processing method for counting active resources or active ports related to set A in the inference operation.

[0058] First aspect of the embodiments

[0059] This application provides a method for configuring a reference signal, which will be described from the perspective of a terminal device.

[0060] Figure 2 is a schematic diagram of a method for configuring a reference signal according to an embodiment of this application. As shown in Figure 2, the method for configuring a reference signal includes:

[0061] 201. The terminal device is configured with a first reference signal set and a second reference signal set respectively. The resource settings of the first reference signal set and the resource settings of the second reference signal set are configured through different channel state information resource configuration identifiers. For the inference operation of the artificial intelligence model or function, the channel state information reference signal resources (CSI-RS resources) in the first reference signal set are not counted as activated resources or activated ports.

[0062] In this application, at least one of the terminal device and the network device is configured with an artificial intelligence model or function for beam management. The beam management can be spatial domain beam prediction (i.e., BM case-1) or temporal beam prediction (i.e., BM case-2).

[0063] Artificial intelligence functionality or model refers to an AI / ML feature or feature group enabled by configuration, where the configuration is supported based on conditions indicated by the capabilities of the end device.

[0064] For example, an AL / ML function or model can be one or more functions or models, or it can be one or more logical models, or it can be one or more sub-functions, or it can be one or more features, or it can be one or more feature groups.

[0065] In this application, the first reference signal set is, for example, set A (Set A), or referred to as set A (Set A) for inference; the second reference signal set is, for example, set B (Set B).

[0066] The operation 201 of this application will now be described through several embodiments.

[0067] Example 1

[0068] In the first alternative scheme, the resource setting of the first reference signal set is configured through a first radio resource control parameter (RRC parameter), which is configured in the channel state information report configuration (CSI-ReportConfig), wherein the channel state information reference signal resources in the first reference signal set are associated with the resource setting.

[0069] In some examples, the first radio resource control parameter can be a new radio resource control parameter, such as resourcesForInference or resourcesForChannelMeasurement2. The channel state information reference signal resources (CSI-RS resources) in the first reference signal set are associated with the resource settings of the first reference signal set. For example, the CSI-RS resources associated with the resource settings configured through resourcesForInference or resourcesForChannelMeasurement2 are the CSI-RS resources in the first reference signal set. These CSI-RS resources are not measured by the terminal device and are not included in the active resources or active ports.

[0070] In the second alternative scheme, the Channel State Information Report Configuration (CSI-ReportConfig) includes multiple resource settings for channel measurement, among which the resource settings for the first reference signal set are preset or configured. Specifically, the channel state information reference signal resources in the first reference signal set are associated with the resource settings of the first reference signal set.

[0071] In some examples, the Channel State Information Reporting (CSI-ReportConfig) configuration includes a list of resource settings for channel measurements, which may include, for example, two or more CSI-ResourceConfigIds. Among these resource settings, the resource settings for the first reference signal set are pre-set or configured; for example, the first CSI-ResourceConfigId, the second CSI-ResourceConfigId, or a CSI-ResourceConfigId with a specific ID (e.g., maximum ID, minimum ID, etc.) corresponds to the first reference signal set.

[0072] In a third alternative scheme, the resource settings of the first reference signal set include a second radio resource control parameter (RRC parameter), which indicates that the channel state information reference signal resources (CSI-RS resources) in the resource settings are not counted as active resources or active ports.

[0073] In some examples, the second radio resource control parameter may be a new radio resource control parameter introduced for the resource configuration of the first reference signal set. This new radio resource control parameter may be added to CSI-ResourceConfig, and may be, for example, transmissionOff. This new radio resource control parameter may indicate that the resource set included in the resource configuration (i.e., the first reference signal set) is not measured by the terminal device and is not counted as an active resource or active port.

[0074] In the fourth alternative scheme, at least one parameter in the resource settings of the first reference signal set includes a first value, wherein if the parameter in the resource settings takes the first value or if the parameter is not configured, the channel state information reference signal resources (CSI-RS resources) in the resource settings are not counted as active resources or active ports.

[0075] In some examples, a new value (i.e., a first value) can be introduced into the resource settings of the first reference signal set. For example, a new value can be introduced into the resource type parameter (resourceType) in the resource settings (e.g., the new value is virtualResource). For the resource settings of the first reference signal set, when the value of the resourceType parameter is set to virtualResource, it means that the resource set included in the resource settings (i.e., the first reference signal set) is not measured by the terminal device and is not counted as an active resource or an active port.

[0076] In other examples, if a parameter in the resource settings of the first reference signal set (e.g., the parameter resource type) is not configured, it means that the resource set included in that resource setting (i.e., the first reference signal set) is not measured by the terminal device and is not counted as an active resource or active port.

[0077] In the fifth alternative scheme, the resource set used for the first reference signal set includes a third radio resource control parameter (RRC parameter) that indicates that the channel state information reference signal resources (CSI-RS resources) in the resource set are not counted as active resources or active ports.

[0078] In some examples, a new Radio Resource Control (RRC) parameter can be introduced into the resource set of the first reference signal set. This new RRC parameter (e.g., a third RRC parameter) is, for example, resourceSetForInference. This new RRC parameter (e.g., resourceSetForInference) can be added to the Non-Zero Power Channel State Information Reference Signal Resource Set (NZP-CSI-RS-ResourceSet) and / or Channel State Information Synchronization Signal Block Resource Set (CSI-SSB-ResourceSet) for the first reference signal set, indicating that this resource set (i.e., the first reference signal set) is not measured by the terminal device and is not counted as an active resource or active port.

[0079] In the sixth alternative scheme, the Channel State Information Reference Signal Resources (CSI-RS resources) used for the first reference signal set include a fourth Radio Resource Control (RRC) parameter, which indicates that the CSI-RS resources are not counted as active resources or active ports, or, when the fourth RRC parameter is not configured, indicates that the CSI-RS resources are not counted as active resources or active ports.

[0080] In some examples, a new Radio Resource Control (RRC) parameter can be introduced into the Channel State Information Reference Signal Resources (CSI-RS resources) of the first reference signal set. This new RRC parameter (e.g., a fourth RRC parameter) could be, for example, forInference. For instance, this new RRC parameter forInference is added to the Non-Zero Power Channel State Information Reference Signal Resources (NZP-CSI-RS-Resource) for the first reference signal set, indicating that this resource is not measured by the terminal device and is not counted as an active resource or active port.

[0081] In other examples, certain parameters in the channel state information reference signal resource (e.g., NZP-CSI-RS-Resource) corresponding to the first reference signal set may not be configured. For example, the parameter resource mapping in the NZP-CSI-RS-Resource corresponding to the first reference signal set may not be configured, indicating that the resource is not measured by the terminal device and is not counted as an active resource or active port.

[0082] In the seventh alternative scheme, the first set of reference signals is configured using a first channel state information reference signal type (CSI-RS type).

[0083] In some examples, a new Channel State Information Reference Signal type (CSI-RS type) can be introduced for the first reference signal set. This new CSI-RS type can be, for example, a Virtual CSI-RS-Resource Set and / or a Virtual CSI-RS-Resource. For instance, the CSI-RS-Resource configured via Virtual-CSI-RS-ResourceSet and / or Virtual-CSI-RS-Resource is not measured by the terminal device and is not counted as an active resource or active port.

[0084] In the eighth alternative scheme, the reference signals in the first reference signal set are configured as zero-power channel state information reference signals (zero-power CSI-RS). The zero-power CSI-RS can be, for example, a zero-power CSI-RS resource set (ZP-CSI-RS-ResoruceSet) and / or a zero-power CSI-RS resource (ZP-CSI-RS-Resource).

[0085] In the ninth alternative, the terminal device's capability related to activated resources or activated ports is extended to be related to the number of resources in the first reference signal set. For example, if the terminal device's original counting capability for activated resources is to count a maximum of M activated resources, and the number of resources in the first reference signal set is N, then the terminal device's counting capability for activated resources or activated ports will be extended to count a maximum of M+N activated resources or activated ports.

[0086] Example 2

[0087] In Embodiment 2, for inference operations, a first reference signal set (e.g., Set A) and a second reference signal set (e.g., Set B) are configured as independent resource sets. The resource settings for the first and second reference signal sets are configured using different Channel State Information Resource Configuration Ids (CSI-ResourceConfigId). The terminal device does not perform measurements on the first reference signal set.

[0088] In some implementations, when the first reference signal set and the second reference signal set are different: the terminal device does not measure or count the channel state information reference signal resources in the first reference signal set as active resources or active ports; in addition, the terminal device measures and counts the channel state information reference signal resources in the second reference signal set as active resources or active ports.

[0089] In other implementations, when the second set of reference signals is a subset of the first set of reference signals:

[0090] The channel state information reference signal resources in the second reference signal set are included in the activated resources or activated ports, while the channel state information reference signal resources in the first reference signal set other than the second reference signal set are not included in the activated resources or activated ports; or, the channel state information reference signal resources in the second reference signal set are included in the activated resources or activated ports, while the channel state information reference signal resources in the first reference signal set are not included in the activated resources or activated ports.

[0091] In other embodiments, when the second reference signal set is a subset of the first reference signal set, the first and second reference signal sets can be configured with reference signal resources (e.g., CSI-RS resources), and some resources in the first and second reference signal sets can be mapped to the same downlink transmit beam (DL Tx Beam). Specifically, when counting active resources or active ports, channel state information reference signal resources in the first reference signal set are not counted as active resources or active ports, while channel state information reference signal resources in the second reference signal set are counted as active resources or active ports.

[0092] Example 3

[0093] In Embodiment 3, the terminal device is configured with a third set of reference signals for performance monitoring of the artificial intelligence model or function. Specifically, for the artificial intelligence model or function on the terminal device side, the performance monitoring can be UE-assisted monitoring and / or NW-side monitoring; for the artificial intelligence model or function on the network device side, the performance monitoring can be NW-side monitoring.

[0094] The channel state information reference signals in the third reference signal set are configured for measurement by the terminal device to obtain ground truth data and / or calculate performance metrics. Furthermore, the channel state information reference signal resources in the third reference signal set are included in the list of active resources or active ports. The third reference signal set is the same as the first reference signal set, or it is a subset of the first reference signal set, or it is different from the first reference signal set, or it is a dedicated resource set(s).

[0095] In the first embodiment, the resource setting ID of the third reference signal set may be the same as or different from the resource setting ID of the first reference signal set. The resource setting ID of the third reference signal set may be, for example, CSI-ResourceConfigId.

[0096] In the second embodiment, the resource setting of the third reference signal set is set by either a first parameter or a second parameter. The first parameter can be an existing parameter in the standard, such as resourcesForChannelMeasurement; the second parameter can be a new parameter introduced into the resource setting of the third reference signal set, such as resourcesForMonitoring.

[0097] In the third embodiment, the resource set of the third reference signal set is the same as the resource set of the first reference signal set, or the resource set of the third reference signal set is different from the resource set of the first reference signal set.

[0098] In the fourth embodiment, when the third reference signal set and the first reference signal set are configured through different resource sets, the mapping relationship between the beam corresponding to the third reference signal set and the beam corresponding to the first reference signal set is explicitly or implicitly defined or configured.

[0099] In Example 1 of the fourth embodiment, the number of resources in the third reference signal set is the same as the number of resources in the first reference signal set. The resources in the third reference signal set are mapped one-to-one with the resources in the first reference signal set. This one-to-one mapping can be a sequential mapping; for example, the first resource in the third reference signal set is mapped to the first resource in the first reference signal set, the second resource in the third reference signal set is mapped to the second resource in the first reference signal set, and so on.

[0100] In Example 2 of the fourth embodiment, the number of resources in the third reference signal set is the same as the number of resources in the first reference signal set. The resources included in the third reference signal set are the same as those included in the first reference signal set; for example, the same CSI-RS resources are included in both the third and first reference signal sets.

[0101] In Example 3 of the fourth embodiment, the number of resources in the third reference signal set is less than the number of resources in the first reference signal set; for example, the third reference signal set is a subset of the first reference signal set. In the configuration of the third reference signal set, a new RRC parameter can be introduced to indicate the mapping between the beam corresponding to the third reference signal set and the beam corresponding to the first reference signal set (or, the new RRC parameter to indicate the mapping between resources in the third reference signal set and resources in the first reference signal set). For example, a list of resource IDs can be configured, the size of which is equal to the number of resources in the third reference signal set. The resource IDs in this list can correspond to resources in the first reference signal set, and the resources in the third reference signal set can be mapped one-to-one to the resources in the first reference signal set indicated by the resource IDs in this list. This one-to-one mapping can be a sequential mapping. The list can be configured in the Channel State Information Report Configuration (CSI-ReportConfig) corresponding to the third reference signal set, or in the resource settings (CSI-ResourceConfig) corresponding to the third reference signal set, or in the Non-Zero Power Channel State Information Reference Signal Resource Set (NZP-CSI-RS-ResourceSet) and / or the Channel State Information Synchronization Signal Block Resource Set (CSI-SSB-ResourceSet) corresponding to the third reference signal set.

[0102] In Example 4 of the fourth embodiment, the number of resources in the third reference signal set is less than the number of resources in the first reference signal set; for example, the third reference signal set is a subset of the first reference signal set. The resources in the third reference signal set are also included in the first reference signal set.

[0103] In the fifth embodiment, the second reference signal set is included in the report configuration for performance monitoring, or the second reference signal set is not included in the report configuration for performance monitoring.

[0104] Example 4

[0105] In Embodiment 4, for inference operations, a first reference signal set (e.g., Set A) and a second reference signal set (e.g., Set B) are configured as independent resource sets. The resource settings for the first and second reference signal sets are configured using different Channel State Information Resource Configuration Ids (CSI-ResourceConfigId). The terminal device does not perform measurements on the first reference signal set.

[0106] In some cases, for the transmission of the Physical Downlink Shared Channel (PDSCH), rate matching or no rate matching is performed on the channel state information reference signal resources of the first reference signal set.

[0107] In other examples, for the transmission of the Physical Downlink Shared Channel (PDSCH), it is determined whether to perform rate matching on the channel state information reference signal resources of the first reference signal set, based on the time-domain characteristics of the inference operation or the time-domain characteristics of the second reference signal set.

[0108] For example, if the inference operation or the second reference signal set is periodic or semi-persistent, then rate matching is performed on the channel state information reference signal resources of the first reference signal set for Physical Downlink Shared Channel (PDSCH) transmission; as another example, if the inference operation or the second reference signal set is aperiodic, then rate matching is not performed on the channel state information reference signal resources of the first reference signal set for Physical Downlink Shared Channel (PDSCH) transmission.

[0109] Example 5

[0110] In Embodiment 5, the terminal device is configured with a third set of reference signals for performance monitoring of the artificial intelligence model or function. Specifically, for the artificial intelligence model or function on the terminal device side, the performance monitoring can be UE-assisted monitoring and / or NW-side monitoring; for the artificial intelligence model or function on the network device side, the performance monitoring can be NW-side monitoring.

[0111] The channel state information reference signals in the third reference signal set are configured for measurement by the terminal device to obtain ground truth data and / or calculate performance metrics. Furthermore, the channel state information reference signal resources in the third reference signal set are included in the list of active resources or active ports. The third reference signal set is the same as the first reference signal set, or it is a subset of the first reference signal set, or it is different from the first reference signal set, or it is a dedicated resource set(s).

[0112] In some cases, for the Physical Downlink Shared Channel (PDSCH), rate matching may or may not be performed on the channel state information reference signal resources of the third reference signal set.

[0113] In other examples, for the Physical Downlink Shared Channel (PDSCH), it is determined whether to perform rate matching on the channel state information reference signal resources of the third reference signal set based on the time-domain characteristics of the resource set of the third reference signal set.

[0114] For example, if the third reference signal set is periodic or semi-persistent, then rate matching is performed on the channel state information reference signal resources of the third reference signal set for Physical Downlink Shared Channel (PDSCH) transmission; as another example, if the third reference signal set is aperiodic, then rate matching is not performed on the channel state information reference signal resources of the third reference signal set for Physical Downlink Shared Channel (PDSCH) transmission.
