[0031] This application provides a measurement method, such as... Figure 1 As shown, when applied to a terminal, the method may include:
[0032] S101. Receive first information, the first information representing the mapping of a port set on different frequency domain resources; measure the mapped port set on different frequency domain resources; and / or determine second information by at least one of the following methods: receive second information, the protocol predefines second information; the second information represents the mapping of a port set on different time domain resources; measure the mapped port set on different time domain resources.
[0033] The measurement method proposed in this application can be applied to CSI prediction model monitoring scenarios, or to other scenarios where the terminal needs to measure the PMI of all ports. The specific method can be selected according to the actual situation, and this application does not impose any specific limitations.
[0034] It should be noted that CSI prediction is based on antenna spatial correlation. An AI model can be applied to the CSI prediction process. The main process involves first measuring the PMI of a subset of ports, then inputting these PMIs into the AI model to predict the PMI of all ports. For the AI model used for CSI prediction, the training samples can be the PMIs of all ports at a given time. During training, the PMIs of a small number of ports are used as input to the AI model, and the PMIs of all ports are used as labels for the AI model's output. The parameters of the AI model can be continuously updated using gradient descent until the error between the AI model's output and the labels is less than a threshold. At this point, the AI model converges, and the aforementioned CSI prediction process can be performed using the AI model.
[0035] It should be noted that the CSI-predicted model monitoring scenario is triggered by events such as the number of NACK responses exceeding a threshold after the aforementioned AI model has been inferring for a period of time. At this point, it is necessary to obtain the actual PMI of all ports to calculate the monitoring Key Performance Indicator (KPI). When the monitoring KPI falls below the threshold, the terminal or network will trigger a model update / model switch / rollback to traditional beam management.
[0036] In this embodiment, the port set of the terminal can be mapped to different frequency domain resources and / or different time domain resources to achieve the measurement mapping of sparsity of the terminal on different time domain resources and / or different frequency domain resources, thereby obtaining the total port PMI in the time domain or frequency domain.
[0037] In one embodiment, assuming that the CSI changes differently on different frequency domain resources, the sparsity of different ports can be mapped to different frequency domain resources. For the mapping of the port set on different frequency domain resources, the terminal can obtain it from the received first information. Then, the terminal measures the mapped port set on different frequency domain resources.
[0038] In the embodiments of this application, the frequency domain resources can be RB, resource element (RE), etc., and the specific selection can be made according to the actual situation. The embodiments of this application do not make specific limitations.
[0039] In one embodiment, the network device is configured to transmit multiple reference signals on different ports on different frequency domain resources. The first information indicated accordingly includes: the correspondence between the reference signals and the port set and / or the mapping density of the reference signals in the frequency domain. The mapping density of the reference signals in the frequency domain is used to determine the frequency domain resources on which the reference signals are mapped.
[0040] It should be noted that the correspondence between the reference signal and the port set can be one-to-one or one-to-many, and the specific choice can be made according to the actual situation. This application embodiment does not make specific limitations.
[0041] In the embodiments of this application, the mapping density of the reference signal in the frequency domain is a value greater than 0 and less than 0.5.
[0042] Optionally, when the mapping density of the reference signal in the frequency domain is 0.2, it means that the reference signal is mapped once for every 5 frequency domain resources; when the mapping density of the reference signal in the frequency domain is 0.25, it means that the reference signal is mapped once for every 4 frequency domain resources; and when the mapping density of the reference signal in the frequency domain is 0.33, it means that the reference signal is mapped once for every 3 frequency domain resources.
[0043] For example, let's take the frequency domain resource RB as an example for the following explanation. With a frequency domain mapping density of 0.25 for the reference signal, when the terminal monitors a 32-port PMI, one reference signal (RS) maps to port 32. The frequency domain range corresponding to RS is RB1-RB50, mapped once every four RBs, onto the first RB in ascending frequency domain order within each group of four RBs, i.e., RB1, RB5, RB9, RB13, ..., RB49. In this case, the frequency domain resources mapped by RS are RB1, RB5, RB9, RB13, ..., RB49.
[0044] For example, when a terminal monitors a 32-port PMI, for four RSs, the frequency domain range of each RS is RB1-RB50. If the mapping density of the reference signal in the frequency domain is 0.25, then RS1 is mapped to RB4k+1, corresponding to ports 1-8; RS2 is mapped to RB4k+2, corresponding to ports 9-16; RS3 is mapped to RB4k+3, corresponding to ports 17-24; and RS4 is mapped to RB4k+4 (k is an integer), corresponding to ports 25-32. Accordingly, the first information will include the mapping density of RS in the frequency domain (0.25) and the port corresponding to each RS; that is, RS1 corresponds to ports 1-8, RS2 corresponds to ports 9-16, RS3 corresponds to ports 17-24, and RS4 corresponds to ports 25-32.
[0045] In one embodiment, the network device is configured to send a reference signal on different ports on different frequency domain resources. The first information indicated accordingly includes: port set configuration and / or port set mapping density in the frequency domain, the port set mapping density in the frequency domain being used to determine the frequency domain resources mapped by the port set.
[0046] In this embodiment of the application, the mapping density of the port set in the frequency domain is a value greater than 0 and less than 0.5.
[0047] For example, the terminal monitors a 32-port PMI, and the network device is configured with four port sets containing ports 1-8, 9-16, 17-24, and 25-32, respectively. The density of the port sets in the frequency domain mapping is 0.25. Then, RB 4k+1 corresponds to ports 1-8, RB 4k+2 corresponds to ports 9-16, RB 4k+3 corresponds to ports 17-24, and RB 4k+4 (where k is a positive integer) corresponds to ports 25-32.
[0048] It should be noted that, based on the two embodiments described above, the terminal reports the PMI of all ports.
[0049] In another embodiment, assuming that CSI changes slowly over time, different port sparsity can be mapped to different time-domain resources. For the mapping of port set on different time-domain resources, the terminal can obtain it from the received second information and / or the second information predefined by the protocol. Then, the terminal measures the mapped port set on different time-domain resources.
[0050] In the embodiments of this application, the time-domain resources may specifically be time slots, symbols, periods, etc., and the specific ones can be selected according to the actual situation. The embodiments of this application do not impose specific limitations.
[0051] In one embodiment, based on the idea of associating a reference signal with different ports at different periods, the network device does not indicate the specific associated port, but directly instructs the terminal to use the same receiving port to perform measurements at different times. The second information received by the terminal includes the number of ports corresponding to the reference signal; and / or, third information, which is used to instruct the terminal to use the same receiving port to perform measurements in different time domain resources.
[0052] For example, if a terminal needs to monitor the PMI of 32 ports, and the base station configures a reference signal with a number of 8 ports, and instructs the terminal to use the same receiving port for measurement on different time domain resources, then the terminal measures the PMI of ports 1-8 in the first cycle, ports 9-16 in the second cycle, ports 17-24 in the third cycle, and ports 25-32 in the fourth cycle.
[0053] Furthermore, the terminal performs a report once after measuring the PMI of the port number in each cycle.
[0054] In one embodiment, based on the idea of associating all ports with a reference signal, the protocol predefines and / or the network device configures the set of ports measured at different times, that is, the correspondence between the port set and time-domain resources. The second information received by the terminal includes at least one of the following:
[0055] Port set configuration;
[0056] The correspondence between port sets and time-domain resources;
[0057] The third information is used to instruct the terminal to use the same receiving port for measurement in different time domain resources;
[0058] The fourth information is used to instruct the terminal to report the port identifier or port set identifier.
[0059] In this embodiment, the port identifier can be a port indicator, port index, bitmap, etc., and the specific one can be selected according to the actual situation. This embodiment does not impose any specific limitations.
[0060] In one embodiment, the second information predefined by the protocol includes: the correspondence between port sets and time-domain resources.
[0061] It should be noted that the correspondence between the above port set and time domain resources can be configured by network devices or predefined by protocols. The specific choice can be made according to the actual situation, and this application embodiment does not impose specific limitations.
[0062] For example, when a terminal monitors a 32-port PMI, the network device configures a reference signal containing 32 ports, and configures port sets 1-4 to contain ports 1-8, 9-16, 17-24, and 25-32, respectively. The network device configures or predefines the protocol to allow the terminal to measure port set 1 in the 4k+1 period, port set 2 in the 4k+2 period, port set 3 in the 4k+3 period, and port set 4 in the 4k+4 period. The network device instructs the terminal to use the same receiving port for measurements across different time-domain resources and instructs the terminal to report port identifiers or port set identifiers.
[0063] Understandably, based on the changing trends of CSI in the frequency and / or time domains, the port set is mapped to different frequency and / or time domain resources. The terminal can measure the mapped port set on different time and / or different frequency domain resources to obtain the PMI of all ports in the time or frequency domains, without having to measure the PMI of all ports in the frequency domain, thus reducing the terminal's measurement overhead.
[0064] Based on the above embodiments, this application also proposes a measurement method applied to network devices, such as... Figure 2 As shown, the method includes:
[0065] S201. Configure first information, which represents the mapping of the port set on different frequency domain resources; and / or configure second information, which represents the mapping of the port set on different time domain resources.
[0066] It should be noted that network devices can configure the first information and / or the second information through higher-level signaling such as Radio Resource Control (RRC).
[0067] In one embodiment, assuming that the CSI changes differently on different frequency domain resources, different port sparsity can be mapped to different frequency domain resources. For the mapping of port sets on different frequency domain resources, the network device can instruct the terminal by configuring first information. Then, the terminal measures the mapped port sets on different frequency domain resources.
[0068] In the embodiments of this application, the frequency domain resources can be RB, RE, etc., and the specific ones can be selected according to the actual situation. The embodiments of this application do not impose specific limitations.
[0069] In one embodiment, the network device is configured to send multiple reference signals to different ports on different frequency domain resources. The first information indicated accordingly includes: the correspondence between the reference signals and the port set and / or the mapping density of the reference signals in the frequency domain, wherein the mapping density of the reference signals in the frequency domain is used to determine the frequency domain resources on which the reference signals are mapped.
[0070] It should be noted that the correspondence between the reference signal and the port set can be one-to-one or one-to-many, and the specific choice can be made according to the actual situation. This application embodiment does not make specific limitations.
[0071] In the embodiments of this application, the mapping density of the reference signal in the frequency domain is a value greater than 0 and less than 0.5.
[0072] In one embodiment, the network device is configured to send a reference signal on different ports on different frequency domain resources, and the first information indicated accordingly includes: port set configuration and / or port set mapping density in the frequency domain, the port set mapping density in the frequency domain being used to determine the frequency domain resources mapped by the port set.
[0073] In this embodiment of the application, the mapping density of the port set in the frequency domain is a value greater than 0 and less than 0.5.
[0074] It should be noted that, based on the two embodiments described above, the terminal reports the PMI of all ports.
[0075] In another embodiment, assuming that CSI changes slowly over time, different port sparsity can be mapped to different time-domain resources. For the mapping of port sets on different time-domain resources, the network device can instruct the terminal by configuring second information. Then, the terminal measures the mapped port sets on different time-domain resources.
[0076] In the embodiments of this application, the time-domain resources may specifically be time slots, symbols, periods, etc., and the specific ones can be selected according to the actual situation. The embodiments of this application do not impose specific limitations.
[0077] In one embodiment, based on the idea of associating a reference signal with different ports at different periods, the network device does not indicate the specific associated port, but directly instructs the terminal to use the same receiving port to perform measurements at different times. The corresponding second information configured by the network device includes: the number of ports corresponding to the reference signal; and / or, third information, which is used to instruct the terminal to use the same receiving port to perform measurements in different time domain resources.
[0078] In one embodiment, based on the idea of associating all ports with a reference signal, the network device configures the set of ports measured at different times, that is, the correspondence between the port set and time-domain resources. The second information configured by the network device includes at least one of the following:
[0079] Port set configuration;
[0080] The mapping between port set identifiers and time-domain resources;
[0081] The third information is used to instruct the terminal to use the same receiving port for measurement in different time domain resources;
[0082] The fourth information is used to instruct the terminal to report the port identifier or port set identifier.
[0083] In this embodiment, the port identifier can be a port indicator, port index, bitmap, etc., and the specific one can be selected according to the actual situation. This embodiment does not impose any specific limitations.
[0084] Furthermore, after configuring the first and / or second information on the network device, the terminal performs port measurements, and then the network device receives at least one of the following pieces of information reported by the terminal:
[0085] Port identifier,
[0086] Port set identifier,
[0087] Rank Indication (RI)
[0088] PMI,
[0089] Channel Quality Indicator (CQI).
[0090] It should be noted that the CSI reported by the terminal to the network device consists of CQI, PMI, and RI. Correspondingly, for the port sets measured and mapped by the terminal in different time domain resources or different frequency domain resources, the terminal can also report the measured port identifier and / or port set identifier to the network device. The specific selection can be made according to the actual situation, and this application embodiment does not impose specific limitations.
[0091] Understandably, based on the changing trends of CSI in the frequency and / or time domains, the port set is mapped to different frequency and / or time domain resources. The terminal can measure the mapped port set on different time and / or different frequency domain resources to obtain the PMI of all ports in the time or frequency domains, without having to measure the PMI of all ports in the frequency domain, thus reducing the terminal's measurement overhead.
