Description

Methods and apparatus for receiving and transmitting 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 18 (NR Rel-18), 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] Beam management includes: spatial domain beam prediction and temporal beam prediction. The network device can configure a set of beams (i.e., reference signals) for measurement (e.g., set B) for the terminal device, and measurements for set B are used as input to AI / ML functions / models. The network device can also configure a set of beams (i.e., reference signals) for prediction (e.g., set A), for example, set A can be used for inference.

[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] In scenarios where AI / ML functions or models are used for beam management, performance monitoring can be performed on the AI / ML functions or models to check their performance, thereby facilitating the control of the AI / ML functions or models. This control may be, for example, at least one of activation, deactivation, selection, switching, and fallback of the AI / ML function or model.

[0007] 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

[0008] For beam management of AI / ML functions or models on the network device side, the network device sends reference signals to the terminal device to obtain ground truth data.

[0013] Receive the reference signal from the first resource set and / or the reference signal from the resource set used for inference.

[0014] The terminal device measures the first resource set to obtain ground truth data.

[0015] The device on the terminal side measures the second resource set, and the measurement result is sent to the device on the network side as input for the artificial intelligence model or function.

[0016] The device on the terminal side does not measure the third resource set, which is used for the output of the artificial intelligence model or function to predict the beam.

[0017] According to another aspect of the embodiments of this application, an apparatus for receiving a reference signal is provided. The apparatus is applied to a terminal device side, and the network device side apparatus is configured with an artificial intelligence model or function for beam management, wherein the beam management includes time-domain beam prediction. The apparatus for receiving the reference signal includes a second communication unit, which is configured to:

[0018] A first resource set configured by the network device side for performance monitoring, and / or a resource set for inference, wherein the resource set for inference includes a second resource set (Set B), or the resource set for inference includes the second resource set (Set B) and a third resource set (Set A); and

[0019] Receive the reference signal from the first resource set and / or the reference signal from the resource set used for inference.

[0061] First aspect of the embodiments

[0062] This application provides a method for receiving a reference signal, which will be described from the perspective of a terminal device.

[0063] Figure 2 is a schematic diagram of a method for receiving a reference signal according to an embodiment of this application. As shown in Figure 2, the method for receiving a reference signal includes:

[0064] 201. A first resource set configured by a device on the network device side for performance monitoring, and / or a resource set for inference, wherein the resource set for inference includes a second resource set (Set B), or the resource set for inference includes the second resource set (Set B) and a third resource set (Set A);

[0065] 202. Receive the reference signal from the first resource set and / or the reference signal from the resource set used for inference.

[0066] In the report transmission method shown in Figure 2, the device on the network equipment side is configured with an artificial intelligence model or function for beam management. Performance monitoring refers to monitoring the performance of the artificial intelligence model or function for beam management, and inference refers to using the artificial intelligence model or function for beam management to perform beam management, which may include, for example, spatial domain beam prediction (i.e., BM Case-1) or temporal beam prediction (i.e., BM Case-2).

[0067] The devices on the network equipment side may include network devices or servers on the network equipment side. The devices on the terminal equipment side may include terminal devices or servers on the terminal equipment side.

[0068] In this application, the terminal device can measure a first resource set to obtain ground truth data. The terminal device sends the measurement results for the first resource set to a network device, which then calculates the performance metrics of the AI ​​model or function used for beam management based on these measurement results. The terminal device can also measure a second resource set, and the measurement results are sent to the network device as input to the AI ​​model or function. For example, the second resource set could be Set B. The terminal device does not measure a third resource set, which is used as the output of the AI ​​model or function to predict beams. For example, the third resource set could be Set A.

[0069] For the first resource set, the second resource set, or the third resource set, each resource set may include, for example, one or more resources, such as channel state information reference signals (CSI-RS) resources.

[0070] The method for receiving reference signals according to this application will now be described with reference to different embodiments.

[0071] Example 1

[0072] In Embodiment 1, beam management includes, for example, spatial domain beam prediction (i.e., BM case-1), and an artificial intelligence model or function for beam management is configured in a device on the network device side.

[0073] In some examples of Embodiment 1, for the inference process, the terminal device is configured with a second resource set but not a third resource set. The terminal device measures the second resource set (i.e., measures the resources within the second resource set) and reports the measurement results to the network device.

[0074] In some other examples of Embodiment 1, for the inference process, the terminal device side is configured with a second resource set and a third resource set. The terminal device side does not measure the third resource set, but measures the second resource set (i.e., measures the resources in the second resource set) and reports the measurement results to the network device side.

[0075] The second and third resource sets can be independent of each other. Furthermore, the second and third resource sets can be configured using the same resource settings or different resource settings.

[0076] In Embodiment 1, for performance monitoring, the device on the terminal device side can be configured with a first resource set. Resources in this first resource set (e.g., CSI-RS) are sent to the device on the terminal device side and measured by the device on the terminal device side.

[0077] Among them, the beam corresponding to the first resource set is the same as the beam corresponding to the third resource set (i.e., the first resource set is the same as the third resource set), or the beam corresponding to the first resource set is a subset of the beam corresponding to the third resource set (i.e., the first resource set is a subset of the third resource set), or the first resource set is a dedicated resource set(s)

[0078] In the first alternative scheme of Embodiment 1:

[0079] The network device-side apparatus configures a dedicated resource set for performance monitoring (i.e., the first resource set is a dedicated resource set) for the terminal device-side apparatus, and configures a dedicated reporting configuration for the terminal device-side apparatus. For example, the terminal device-side apparatus is configured with independent Channel State Information (CSI) reporting configurations for inference and for performance monitoring, wherein the CSI reporting configurations for inference and for performance monitoring may be associated or unassociated.

[0080] In the second alternative scheme of Embodiment 1:

[0081] The network device-side apparatus configures a dedicated resource set for performance monitoring (i.e., the first resource set is a dedicated resource set) for the terminal device-side apparatus, and configures channel state information (CSI) reports for inference and channel state information (CSI) reports for performance monitoring through the same reporting configuration.

[0082] In the third alternative scheme of Embodiment 1:

[0083] The first resource set and the resource set for inference are configured with the same Channel State Information (CSI) report configuration, and the Channel State Information (CSI) report for inference and the Channel State Information (CSI) report for performance monitoring are configured with different report configurations.

[0084] In the fourth alternative scheme of Embodiment 1:

[0085] The first resource set and the resource set for inference are configured using the same Channel State Information (CSI) report configuration, and the Channel State Information (CSI) report for inference and the Channel State Information (CSI) report for performance monitoring are configured using the same report configuration.

[0086] In some examples of Example 1, the following schemes may be used when reporting measurement results for performance monitoring:

[0087] Send beam ID(s), for example, report only beam IDs, where the beam ID can be the reference signal identifier of the strongest one or the K strongest beams, where K is a natural number; or

[0088] Transmit beam ID(s) and Layer 1 Reference Signal Received Power (L1-RSRP), wherein the beam ID can be the reference signal identifier of the strongest beam or the K strongest beams, where K is a natural number.

[0089] For example, when reporting beam ID(s) and Layer 1 Reference Signal Received Power (L1-RSRP), if the report is made for all beams in the first resource set, the report of the measurement results for performance monitoring includes the Layer 1 Reference Signal Received Power (L1-RSRP) of all beams in the first resource set and a beam ID, wherein the beam ID corresponds to the beam with the largest Layer 1 Reference Signal Received Power (L1-RSRP) measured in the first resource set.

[0090] In the above scheme, it is configurable whether to report only the beam identifier or to report both the L1-RSRP and the beam identifier.

[0091] In some examples of Embodiment 1, when reporting measurement results for performance monitoring, the reporting of these measurement results may use either a first report quantity or a second report quantity. The first report quantity may be a new report quantity; the second report quantity may be a reused traditional report quantity, which differs from the first report quantity.

[0092] In some examples of Embodiment 1, the transmission timing of the first resource set may or may not be associated with the transmission timing of the second resource set, wherein the association may be predefined or configured in an explicit or implicit manner.

[0093] For example, the transmission timing of the first resource set is associated with the transmission timing of the nearest second resource set, and the transmission timing of the first resource set is before or after the transmission timing of the nearest second resource set, wherein the transmission timing of the nearest second resource set is determined based on a specific symbol in the first resource set and / or a specific symbol in the second resource set, the specific symbol being the first symbol, the last symbol, or an intermediate symbol.

[0094] For example, the transmission timing of the first resource set is associated with the transmission timing of the nearest second resource set, and the transmission timing of the first resource set is before or after the transmission timing of the nearest second resource set. The time interval between the transmission timing of the first resource set and the transmission timing of the nearest second resource set is within a predetermined time window. The transmission timing of the nearest second resource set is determined based on specific symbols in the first resource set and / or specific symbols in the second resource set; these specific symbols can be the first symbol, the last symbol, or an intermediate symbol. Furthermore, if there is no transmission timing of the nearest second resource set within the predetermined time window, the measurement results corresponding to the transmission timing of the first resource set will not be used for performance indicator calculations.

[0095] Example 2

[0096] In Embodiment 2, beam management includes, for example, time-domain beam prediction (i.e., BM case-2), and an artificial intelligence model or function for beam management is configured in a device on the network device side.

[0097] In some examples of Embodiment 2, for the inference process, the terminal device is configured with a second resource set but not a third resource set. The terminal device measures the second resource set (i.e., measures the resources within the second resource set) and reports the measurement results to the network device.

[0098] In some other examples of Embodiment 2, for the inference process, the terminal device side is configured with a second resource set and a third resource set. The terminal device side does not measure the third resource set, but measures the second resource set (i.e., measures the resources in the second resource set) and reports the measurement results to the network device side.

[0099] The second and third resource sets can be independent of each other. Furthermore, the second and third resource sets can be configured using the same resource settings or different resource settings.

[0100] In some examples of Embodiment 2, the second resource set may be configured with a periodic or semi-persistent resource set.

[0101] For example, the second resource set is configured as a periodic or semi-persistent resource set that is transmitted over multiple time instances. In addition, multiple time offsets can be configured for the first resource set, such as a list of time offsets.

[0102] For example, the second resource set is configured with multiple periodic or semi-persistent resource sets, where one periodic or semi-persistent resource set corresponds to one time instance.

[0103] In some other examples of Embodiment 2, the second resource set is configured as an aperiodic resource set, or the second resource set does not support being configured as an aperiodic resource set.

[0104] For example, the second resource set can be configured as an aperiodic resource set, which is transmitted across multiple time instances. Furthermore, this aperiodic resource set can be configured with multiple aperiodicTriggeringOffset values, each corresponding to a time instance. Triggering refers to transmitting resources from the aperiodic resource set within the corresponding time instance.

[0105] For example, the second resource set can be configured with multiple aperiodic resource sets, where each aperiodic resource set corresponds to a time instance. These multiple aperiodic resource sets are triggered by the same downlink control information (DCI) or by at least two different downlink control information. Triggering means that the downlink control information (DCI) triggers the transmission of resources within the aperiodic resource set.

[0106] In Example 2, when configuring a third resource set, multiple third resource sets can be configured, and each third resource set corresponds to a point in time within a prediction window. The number of resources in each third resource set can be the same or different.

[0107] In Embodiment 2, for performance monitoring, the device on the terminal device side can be configured with a first resource set. The resources in this first resource set (e.g., CSI-RS) are sent to the device on the terminal device side and measured by the device on the terminal device side.

[0108] Among them, the beam corresponding to the first resource set is the same as the beam corresponding to the third resource set (i.e., the first resource set is the same as the third resource set), or the beam corresponding to the first resource set is a subset of the beam corresponding to the third resource set (i.e., the first resource set is a subset of the third resource set), or the first resource set is a dedicated resource set(s)

[0109] In some examples, the first resource set can be configured to be transmitted over one or more time instances, which may be explicitly configured, implicitly configured, or predefined.

[0110] For example, a first resource set can be configured to be transmitted across multiple time instances, and the first resource set can be configured with multiple time offsets (e.g., a list of time offsets can be configured with multiple time offsets).

[0111] For example, multiple first resource sets can be configured, and each first resource set corresponds to one time instance. These multiple first resource sets are configured within the same Channel State Information Resource Configuration (CSI-ResourceConfig). For instance, if there are four prediction time instances (i.e., #1, #2, #3, and #4) within the prediction window, two first resource sets can be configured to transmit in time instances #1 and #2, respectively.

[0112] In the first alternative scheme of Embodiment 2:

[0113] The network device-side apparatus configures a dedicated resource set for performance monitoring (i.e., the first resource set is a dedicated resource set) for the terminal device-side apparatus, and configures a dedicated reporting configuration for the terminal device-side apparatus. For example, the terminal device-side apparatus is configured with independent Channel State Information (CSI) reporting configurations for inference and for performance monitoring, wherein the CSI reporting configurations for inference and for performance monitoring may be associated or unassociated.

[0114] In the second alternative scheme of Embodiment 2:

[0115] The network device-side apparatus configures a dedicated resource set for performance monitoring (i.e., the first resource set is a dedicated resource set) for the terminal device-side apparatus, and configures channel state information (CSI) reports for inference and channel state information (CSI) reports for performance monitoring through the same reporting configuration.

[0116] In the third alternative scheme of Embodiment 2:

[0117] The first resource set and the resource set for inference are configured with the same Channel State Information (CSI) report configuration, and the Channel State Information (CSI) report for inference and the Channel State Information (CSI) report for performance monitoring are configured with different report configurations.

[0118] In the fourth alternative scheme of embodiment 2:

[0119] The first resource set and the resource set for inference are configured using the same Channel State Information (CSI) report configuration, and the Channel State Information (CSI) report for inference and the Channel State Information (CSI) report for performance monitoring are configured using the same report configuration.

[0120] In some examples of Example 2, the following schemes may be used when reporting measurement results for performance monitoring:

[0121] Send beam ID(s), for example, report only beam IDs, where the beam ID can be the reference signal identifier of the strongest one or the K strongest beams, where K is a natural number; or

[0122] Transmit beam ID(s) and Layer 1 Reference Signal Received Power (L1-RSRP), wherein the beam ID can be the reference signal identifier of the strongest beam or the K strongest beams, where K is a natural number.

[0123] For example, when reporting beam ID(s) and Layer 1 Reference Signal Received Power (L1-RSRP), if the report is made for all beams in the first resource set, the report of the measurement results for performance monitoring includes the Layer 1 Reference Signal Received Power (L1-RSRP) of all beams in the first resource set and a beam ID, wherein the beam ID corresponds to the beam with the largest Layer 1 Reference Signal Received Power (L1-RSRP) measured in the first resource set.

[0124] In the above scheme, it is configurable whether to report only the beam identifier or to report both L1-RSRP and the beam identifier.

[0125] In some examples of Embodiment 2, when reporting measurement results for performance monitoring, the reporting of these measurement results may use either a first report quantity or a second report quantity. The first report quantity may be a new report quantity; the second report quantity may be a reused traditional report quantity, which differs from the first report quantity.

[0126] In Example 2, when reporting measurement results for performance monitoring, a performance monitoring report may include measurement results for one time instance or measurement results for multiple time instances. Information about the time instances may be reported explicitly or implicitly in the report.

[0127] In some cases, when reporting Layer 1 Reference Signal Received Power (L1-RSRP), the device on the terminal equipment side can transmit the Layer 1 Reference Signal Received Power (L1-RSRP) in differential form.

[0128] In other examples, if a report contains measurements for multiple time instances, differential form of Layer 1 reference received power (L1-RSRP) can be applied to those multiple time instances, wherein the Layer 1 reference received power used for reference in differential form of Layer 1 reference received power (L1-RSRP) comes from the strongest beam measured at the multiple time instances.

[0129] In some examples of Embodiment 2, the transmission timing of the first resource set may or may not be associated with the transmission timing of the second resource set, wherein the association may be predefined or configured in an explicit or implicit manner.

[0130] For example, the transmission timing of the first resource set is associated with the transmission timing of the nearest second resource set, and the transmission timing of the first resource set is before or after the transmission timing of the nearest second resource set, wherein the transmission timing of the nearest second resource set is determined based on a specific symbol in the first resource set and / or a specific symbol in the second resource set, the specific symbol being the first symbol, the last symbol, or an intermediate symbol.

[0131] For example, the transmission timing of the first resource set is associated with the transmission timing of the nearest second resource set, and the transmission timing of the first resource set is before or after the transmission timing of the nearest second resource set. The time interval between the transmission timing of the first resource set and the transmission timing of the nearest second resource set is within a predetermined time window. The transmission timing of the nearest second resource set is determined based on specific symbols in the first resource set and / or specific symbols in the second resource set; these specific symbols can be the first symbol, the last symbol, or an intermediate symbol. Furthermore, if there is no transmission timing of the nearest second resource set within the predetermined time window, the measurement results corresponding to the transmission timing of the first resource set will not be used for performance indicator calculations.
