Detailed Description
The present application will be described in further detail with reference to the accompanying drawings and examples.
First, problems with AI-based beam management in the related art are described in connection with an exemplary application scenario.
Typical use cases of AI-based beam management are beam prediction/tracking at high speed movement, possibly including both time-and space-dimensional beam prediction. Wherein, the time dimension beam prediction means that the measured beam quality is used for predicting the beam quality in a future period of time; spatial dimension beam prediction refers to predicting unmeasured beam quality using measured beam quality.
For example, as shown in fig. 1, for conventional beam tracking (i.e., non-AI beam tracking), the beam tracking frequency may be set to be once every 20 milliseconds (ms), and the User Equipment (UE) measures the reporting portion beam quality each time in accordance with a configuration of the network side, such as CSI reporting configuration (CSI-ReportConfig). In this case, when performing AI-based beam prediction, the time interval between beam tracking adjacent sampling points (i.e., measurement moments) may be set to 100 milliseconds (ms), and the UE may predict the quality of the best beam among the partial beams in the next 900ms or the quality of the best beam among all the beams in the next 900ms based on the partial beam quality measured at the consecutive two sampling points. The UE may then send a beam report to the network side in a specific transmission manner.
As can be seen from the above description, when the UE performs AI-based beam prediction, it is required to measure beam quality at a plurality of consecutive sampling points, that is, measure a reference signal resource set multiple times, and report the measurement result and/or the prediction result to the network side. Here, the reference signal resource sets measured at a plurality of consecutive sampling points can be considered to constitute a combination (bundle) of the reference signal resource sets.
However, the information reporting framework (such as CSI reporting framework) in the related art only supports measurement of the reference signal resource set once per reference signal resource allocation period/measurement, and does not support allocation of the bundle-based reference signal resource set measurement. Moreover, the network side can only instruct the UE to report the beam quality in the past time which has been measured, but cannot instruct the UE to report the beam quality in a future period of time, i.e. cannot instruct the UE to report the predicted reference signal resource quality.
In summary, the related art does not define how the UE measures and reports when performing AI-based beam management.
Based on this, in various embodiments of the present application, an information reporting framework (such as a CSI reporting framework) in the related art is enhanced to indicate bundle-based reference signal resource set measurements and/or beam quality reporting for a future period of time. The network side may configure an identification range of a reference signal resource (i.e., a beam) reported by the terminal at a first time, so that the terminal can report a reference signal resource quality (i.e., a beam quality) which is not measured by itself and is based on AI prediction at the first time, i.e., report a beam prediction result based on a spatial dimension of AI, thereby implementing AI-based beam management. The network side can configure the time range of the reference signal resource quality reported by the terminal, so that the terminal can predict and report the reference signal resource quality in a future period of time based on the AI, namely report the beam prediction result based on the time dimension of the AI, and the beam management based on the AI is realized. The network side can configure the terminal to measure the first reference signal resource set at N times (N is an integer greater than or equal to 1), so that the terminal can measure the reference signal resource set N times in each reference signal configuration period, namely, the measurement of the reference signal resource set based on bundle is realized; further, AI-based beam management can be performed using the measurement results of the bundle-based reference signal resource set, such as time-dimensional beam prediction and/or space-dimensional beam prediction using the measurement results of the bundle-based reference signal resource set.
The embodiment of the application provides a configuration method, which is applied to a terminal and comprises the following steps:
receiving configuration information sent by a network side, wherein the configuration information comprises at least one of the following components:
first information indicating that a first set of reference signal resources is measured at N times, N being an integer greater than or equal to 1;
the second information indicates the identification range of the reference signal resource reported at the first moment;
and third information, wherein the third information indicates the time range of the reported reference signal resource quality.
In practical application, the terminal may also be referred to as UE, and may also be referred to as a user.
In practical application, the type of the reference signal corresponding to the first reference signal resource set may be set according to requirements, for example, CSI-RS, SRS, SSB, etc., and the embodiment of the present application does not limit the type of the reference signal resource.
Based on this, in an embodiment, the reference signals corresponding to the first set of reference signal resources include at least one of:
CSI-RS；
SRS；
SSB。
in practical application, based on the type of the reference signal corresponding to the first reference signal resource set, the network side may send the configuration information through different Information Elements (IEs). For example, in the case that the type of the reference signal corresponding to the first reference signal resource set includes CSI-RS, the network side may send the configuration information through an IE in CSI-ReportConfig; in other words, the network side may carry the configuration information to the terminal sending the IE in CSI-ReportConfig, CSI-ReportConfig.
In practical application, the quality of the reference signal resource may be understood as the quality of the corresponding reference signal, i.e. the beam quality, such as at least one of parameters including Reference Signal Received Power (RSRP), received Signal Strength Indicator (RSSI), and signal-to-noise ratio (SNR), which may be specifically set according to the needs, and the type of the parameter reflecting the quality of the reference signal resource is not limited in the embodiment of the present application.
In actual use, the identification of the reference signal resource may include an ID (i.e., index) of the reference signal resource.
In practical application, the network side can send the configuration information through RRC signaling.
Based on this, in an embodiment, the receiving the configuration information sent by the network side may include:
and receiving RRC signaling, wherein the RRC signaling comprises the configuration information.
In practical application, the measuring the first reference signal resource set at N times may be understood as measuring N first reference signal resource sets, in other words, the network side may use the reference signal resource set as a basic unit, and repeatedly send the first reference signal resource set N times as the first reference signal resource set bundle.
Based on this, in an embodiment, the first information may include fourth information and fifth information; the fourth information characterizes the number of times N of repeated transmission of the first reference signal resource set; the fifth information characterizes a time interval of the first set of reference signal resources when two adjacent transmissions are repeated (i.e., a time interval between two adjacent ones of the N times).
In practical application, it may be understood that N is the number of the first reference signal resource sets included in the first reference signal resource set bundle, and the value of N may be set according to the requirement, which is not limited in the embodiment of the present application.
In practical application, when the network side configures the first information, reference signal resources may also be used as basic units; in other words, the network side may repeatedly send the reference signal resources in the first reference signal resource set N times, so as to achieve the same effect as that of sending the first reference signal resource set bundle.
Based on this, in an embodiment, the first information may include sixth information and seventh information; the sixth information characterizes the number of times N of repeated transmission of the reference signal resources in the first reference signal resource set; the seventh information characterizes a time interval of reference signal resources in the first set of reference signal resources when two adjacent transmissions are repeated (i.e., a time interval between two adjacent ones of the N times).
In practical application, the first information may be understood as a time domain resource position of a first reference signal resource set that needs to be measured by the terminal configured at the network side.
In practical application, all reference signal resources in the first reference signal resource set repeatedly sent by the network side may need to be measured; in other words, the terminal may measure all of the reference signal resources in the first set of reference signal resources at each of the N times.
In practical applications, it is considered that, along with the movement of the terminal, the terminal may not receive the partial reference signal corresponding to the first reference signal resource set, or the received partial reference signal has poor quality (such as weak signal strength). Therefore, in order to save resources, the network side may configure the terminal to measure only part of the reference signal resources in the first reference signal resource set that the network side repeatedly transmits at different times, i.e. to measure the same or different subset of the first reference signal resource set at each of the N times.
Based on this, in an embodiment, in a case where the configuration information includes the first information, the method may further include:
and receiving tenth information sent by the network side, wherein the tenth information indicates at least one reference signal resource in the first reference signal resource set.
In practical applications, the tenth information may indicate that at least one reference signal resource in one first reference signal resource set is measured, i.e. a reference signal resource that needs to be measured at one of the N times. Specifically, in the case where the tenth information is received before receiving the reference signal corresponding to one of the first reference signal resource sets in the first reference signal resource set bundle, the tenth information may indicate at least one reference signal resource in the first reference signal resource set measured at the next measurement time.
In practical application, the tenth information may also indicate at least one reference signal resource to be measured at each of the N times, where the at least one reference signal resource to be measured at each time may be the same or different.
In practical application, the network side can indicate the reference signal resource through the reference signal resource identifier. Illustratively, the reference signal resource identification may include at least one of:
CSI-RS identification (such as ID);
SRS identification;
SSB identification.
In practical application, the network side may also indicate the reference signal resource through a Bitmap (Bitmap). Illustratively, assume a Bitmap form of 1100, the first set of reference signal resources includes four reference signal resources, and the IDs of the four reference signal resources are 0, 2, 4, 6, respectively; the terminal only needs to measure two reference signal resources of the first reference signal resource set ID of 0 and 2 at the corresponding time.
In practical application, the network side can send the tenth information through the MAC CE.
Based on this, in an embodiment, the receiving tenth information sent by the network side may include:
and receiving a MAC CE, wherein the MAC CE comprises the tenth information.
In practical application, the network side may also send the tenth information through DCI.
Based on this, in an embodiment, the receiving tenth information sent by the network side may include:
and receiving DCI, wherein the DCI comprises the tenth information.
In practical application, when the network side configures the identification range of the reference signal resource reported by the terminal at the first moment, the network side can indicate the reference signal resource set and the optimal beam quantity required to be reported.
Based on this, in an embodiment, the second information may include at least one of:
a second set of reference signal resources;
the reference signal resource quality satisfies a number of reference signal resources of the first condition.
In practical application, the terminal may perform beam prediction based on the second information and based on the spatial dimension of AI, that is, based on AI and measured reference signal resources at the first time, predict quality of unmeasured reference signal resources in the combined set of the first reference signal resource set and the second reference signal resource set.
In practical application, the second reference signal resource set may include all reference signal resources that the terminal needs to predict based on AI; in other words, the second set of reference signal resources may include all reference signal resources in the first set of reference signal resources, and the terminal other than all reference signal resources in the first set of reference signal resources may need AI-prediction-based reference signal resources.
In practical application, the second reference signal resource set may also include reference signal resources that need to be predicted based on AI, except for the reference signal resources that need to be measured by the terminal configured by the network side; in other words, the second set of reference signal resources may only contain reference signal resources that the terminal needs to be AI-prediction-based, except for all reference signal resources in the first set of reference signal resources.
In practical application, the number of reference signal resources whose reference signal resource quality satisfies a first condition may be understood as the number of optimal beams that the terminal needs to report at the first time; in other words, the first condition may characterize that the measured or predicted reference signal resource quality is optimal in a union of the first set of reference signal resources and the second set of reference signal resources.
In practical application, in the case that the configuration information includes the second information, the configuration information may further include eleventh information indicating that beam prediction of AI-based spatial dimensions is turned on.
In practical application, in the case that the configuration information does not include the second information, the configuration information may further include twelfth information indicating that the beam prediction of the AI-based spatial dimension is not turned on. At this time, the terminal may use a conventional beam management method, that is, only measure and report the reference signal resources (such as the first reference signal resource set) configured on the network side and required to be measured.
In practical application, the terminal may report, to the network side, the quality of the reference signal resource measured in a past time range, such as the quality of the first reference signal resource set measured in past N times, based on the third information.
In practical application, the terminal may also perform beam prediction based on the time dimension of AI based on the third information, that is, predict the quality of reference signal resources of a plurality of sampling points (i.e., prediction moments) in the future.
In practical application, the network side can indicate the time range of the reported reference signal resource quality to the terminal through the number of the predicted time and the time interval between two adjacent predicted time.
Based on this, in an embodiment, the third information may include the number of times M and a time interval between two adjacent times among M times, M being an integer greater than or equal to 1.
In practical application, the terminal may predict and report the reference signal resource quality of M future times from the time corresponding to the last reference signal resource in the first reference signal resource set bundle according to the third information.
In practical application, the network side can indicate the time range of the reported reference signal resource quality to the terminal through the time interval between two adjacent prediction moments and the prediction duration.
Based on this, in an embodiment, the third information may include a first duration and a first time interval.
In actual application, the terminal may predict, according to the third information, the quality of the reference signal resource when reaching the first time interval each time in a first time length in the future from the time corresponding to the last reference signal resource in the first reference signal resource set bundle; in other words, the terminal may divide the first time period by the first time period to obtain the number M of predicted time periods, that is, the time period between two adjacent time periods in the M time periods is the first time period, and predict and report the reference signal resource quality of the M time periods in the future from the time period corresponding to the last first reference signal resource set in the first reference signal resource set bundle according to the third information.
In practical application, when the network side indicates the time range of the reported reference signal resource quality to the terminal through the number of the predicted time and the time interval between two adjacent predicted time, the starting time of the time range can also be indicated.
Based on this, in an embodiment, the third information may include eighth information, the number M of times, M being an integer greater than or equal to 1, and a time interval between adjacent two times among M times; the eighth information characterizes a time offset of a first time instant from a second time instant of the M time instants.
Here, the first time of the M times may be understood as a starting time of a time range of the reference signal resource quality reported by the terminal.
In practical application, when the network side indicates the time range of the reported reference signal resource quality to the terminal through the time interval between two adjacent predicted moments and the predicted duration, the starting moment of the time range can also be indicated.
Based on this, in an embodiment, the third information may include ninth information, a first duration, and a first time interval; the ninth information characterizes a time offset of a start time of the first duration relative to a second time.
Here, the starting time of the first duration may be understood as a starting time of a time range of the reference signal resource quality reported by the terminal.
In practical application, the second time may include a time corresponding to a first reference signal resource in the first reference signal resource set bundle; in other words, the starting moment of beam prediction based on the time dimension of AI can be obtained by adding the time offset represented by the eighth information or the ninth information to the time domain resource position of the reference signal resource sent by the network side for the first time in the first reference signal resource set bundle.
In practical application, the second time may include a time corresponding to a last reference signal resource in the first reference signal resource set bundle; in other words, the starting moment of beam prediction based on the time dimension of AI can be obtained by adding the time offset represented by the eighth information or the ninth information to the time domain resource position of the reference signal resource transmitted by the network side in the first reference signal resource set bundle for the last time.
In practical application, in the case that the configuration information includes the third information, the configuration information may further include thirteenth information indicating that the beam prediction based on the AI-based time dimension is turned on.
In practical application, in the case that the configuration information does not include the third information, the configuration information may further include fourteenth information indicating that the AI-based time dimension beam prediction is not turned on. At this time, the terminal may measure and report the reference signal resource (for example, the first reference signal resource set) configured by the network side and required to be measured.
In practical application, the terminal can measure and/or predict according to the configuration information and send a measurement result and/or a prediction result to the network side.
For example, assuming that the base station has eight transmission beams and the terminal has two reception beams, as shown in fig. 2, when performing non-AI beam tracking, the network side may configure a CSI-RS resource set of CSI-ReportConfig (i.e., the first reference signal resource set) to include four reference signals/transmission beams (i.e., four CSI-RS resources), and configure a transmission period of the CSI-RS resource set to be 20ms. When performing AI-based beam prediction, the network side may configure a CSI-RS resource set of CSI-ReportConfig (i.e., the first reference signal resource set) to include four reference signals/transmit beams (i.e., four CSI-RS resources), where the IDs of the four CSI-RS resources are assumed to be 0, 2, 4, and 6, respectively, and the CSI-RS resource set period is 1 second(s). And, the network side may configure the fourth information to be 2 and the fifth information to be 100 slots (assuming 1 slot=1 ms); namely, two CSI-RS resource sets form a bundle in each CSI-RS resource set period, and the time interval between the two CSI-RS resource sets is 100 time slots; the terminal needs to measure all CSI-RS resources within the two CSI-RS resource sets.
If the terminal receives a partial signal corresponding to the CSI-RS resource set (i.e., receives the tenth information) indicated by the MAC CE or the DCI before receiving the signal corresponding to the CSI-RS resource set at a certain moment, for example, the received MAC CE or the DCI includes a Bitmap with 1100, only the CSI-RS resources with ID 0 and 2 in the resource set are measured at the moment.
Assuming beam prediction in the spatial dimension is turned on (i.e. the configuration information includes the eleventh information), the network side may indicate the second reference signal resource set by configuring the reference signal resource set identifier, and may configure the number of reference signal resources whose reference signal resource quality satisfies the first condition to be 4; at this time, it is assumed that IDs of eight CSI-RS resources included in the second reference signal resource set are respectively 0 to 7, and the terminal needs to predict and report the quality of 4 optimal beams in the eight CSI-RS resources with the IDs of 0 to 7 at each sampling point moment.
Assuming beam prediction in the on-time dimension (i.e. the configuration information includes the thirteenth information), the network side may configure the value of M to 45, and configure the time interval between two adjacent time instants of 45 time instants to 20; at this time, the terminal needs to predict and report beam quality of 45 sampling points in the future from the last CSI-RS resource in the CSI-RS resource set bundle, and the time interval between two adjacent sampling points is 20 slots (i.e. 20 ms).
Assuming beam prediction in the on-time dimension, the network side may also configure the first time length to 900 and configure the first time interval to 20; at this time, the terminal needs to predict and report beam quality within 900ms in the future from the last CSI-RS resource in the CSI-RS resource set bundle, and the time interval between two adjacent sampling points is 20ms.
Correspondingly, the embodiment of the application also provides a configuration method which is applied to the network equipment (particularly can comprise a base station) and comprises the following steps:
transmitting configuration information to the terminal, wherein the configuration information comprises at least one of the following components:

the second information indicates the identification range of the reference signal resource reported at the first moment;
and third information, wherein the third information indicates the time range of the reported reference signal resource quality.
Wherein in an embodiment, in a case that the configuration information includes the first information, the method may further include:
tenth information is sent to the terminal, the tenth information indicating at least one reference signal resource in the first set of reference signal resources.
In an embodiment, the sending tenth information to the terminal may include:

The scheme provided by the embodiment of the application enhances an information reporting framework (such as a CSI reporting framework) in the related technology so as to indicate the measurement of the reference signal resource set based on bundle and/or the beam quality reporting of a future period of time. The network side may configure an identification range of a reference signal resource reported by the terminal at a first time, so that the terminal can report the quality of the reference signal resource which is not measured by itself based on AI prediction at the first time, that is, report a beam prediction result based on the spatial dimension of the AI, thereby realizing beam management based on the AI. The network side can configure the time range of the reference signal resource quality reported by the terminal, so that the terminal can predict and report the reference signal resource quality in a future period of time based on the AI, namely report the beam prediction result based on the time dimension of the AI, and the beam management based on the AI is realized. The network side can configure the terminal to measure the first reference signal resource set at N times (N is an integer greater than or equal to 1), so that the terminal can measure the reference signal resource set N times in each reference signal configuration period, namely, the measurement of the reference signal resource set based on bundle is realized; further, AI-based beam management can be performed using the measurement results of the bundle-based reference signal resource set, such as time-dimensional beam prediction and/or space-dimensional beam prediction using the measurement results of the bundle-based reference signal resource set.
