The network element may be virtual or physical. The core network may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC).

[0164] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution provided by the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution provided by the embodiment of the present disclosure is also applicable to similar technical problems.

[0165] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1A , or a portion thereof, but are not limited thereto.

[0167] FIG1B shows a mapping relationship between a UCI bit sequence and a corresponding CSI report. In FIG1B , the UCI bit sequence starts from the low bit (a0 (2) ) to the high bit (a A-1 2)) increases. The index number of the CSI report may be positively correlated with the index number of the CSI report configuration corresponding to the CSI report.

[0168] In the message structure of the UCI sending the CSI report shown in FIG1B , a CSI report is completely mapped to the UCI.

[0169] For some types of CSI-reports, the payload of the CSI-report is relatively large. In this case, the CSI-report can be sent in two parts, that is, the payload of the CSI-report to be reported is divided into two parts.

[0170] When the CSI-report is divided into two parts, the mapping relationship between the CSI-report and the bit sequence is shown in Figure 1C. In the content shown in Figure 1C, similar to the mapping relationship in Figure 1B, the index number of the CSI report configuration corresponding to the CSI-report is mapped to the UCI bit sequence.

[0171] Figure 1C shows a mapping relationship between a UCI bit sequence and a corresponding CSI report. In Figure 1C, the UCI is mapped to the CSI report in parts. For example, the UCI shown in Figure 1C is mainly mapped to part 2 of the CSI report and when mapping, the UCI bit sequence is also mapped from the low bit (a0) to the high bit (a1). A-1 ) increases. The index number of the CSI report may be positively correlated with the index number of the CSI report configuration corresponding to the CSI report.

[0172] Furthermore, when there are insufficient CSI resources for transmitting the CSI-report, the terminal may discard part (or omit) or all of part 2 and send only part 1 (part 1) of the CSI-report to the network device. Sending only part 1 of the UCI may be as shown in FIG1D .

[0173] Figure 1D shows a mapping relationship between a UCI bit sequence and a corresponding CSI report. In Figure 1D, the UCI is mapped to the CSI report in parts. For example, the UCI shown in Figure 1C mainly maps to part 1 of the CSI report and when mapping, the UCI bit sequence is also mapped from the low bit (a0) to the high bit (a1). A-1 ) increases. The index number of the CSI report may be positively correlated with the index number of the CSI report configuration corresponding to the CSI report.

[0174] In order to improve the flexibility of downlink channel measurement and to improve the efficiency of terminal sending CSI-report, the information processing method or CSI report transmission method provided in the embodiment of the present disclosure supports network equipment to configure multiple sub-configurations and supports the terminal to selectively report some sub-CSI reports.

[0175] FIG2 is an interactive diagram illustrating an information processing method according to an embodiment of the present disclosure. As shown in FIG2 , the present disclosure embodiment relates to an information processing method for a communication system 100, the method comprising:

[0176] S2101: The network device sends at least one CSI report configuration.

[0177] In some embodiments, the network device sends a Radio Resource Control (RRC) message, wherein the RRC message includes a CSI reporting configuration.

[0178] In some embodiments, the at least one CSI reporting configuration includes one or more sub-CSI reporting configurations.

[0179] The sub-CSI report configuration corresponds to a downlink transmission mode of the network device. In some embodiments, different sub-CSI report configurations correspond to different downlink transmission modes.

[0180] In some embodiments, the network device sends part or all of the sub-report configurations corresponding to the downlink transmission mode to the UE based on the supported downlink transmission mode.

[0181] In some embodiments, the downlink transmission mode of the network device is related to the SD used for downlink transmission or the transmit power. For example, different downlink transmission modes have different SDs. For another example, different downlink transmission modes have different transmit powers.

[0182] In some embodiments, the network device may first determine the downlink transmission mode supported by the UE, and send part or all of the sub-report configurations corresponding to the downlink transmission mode to the UE.

[0183] In some embodiments, the CSI sub-report configuration may include one or more of the following:

[0184] Transmission parameters of the measured reference signal, including but not limited to time-frequency resource location, whether beam transmission is used, and / or transmission direction when beam transmission is used;

[0185] Indication of the reported quantity.

[0186] In some embodiments, the reporting amounts defined by different sub-configurations may be the same or different.

[0187] In some embodiments, a network device may send one or more CSI reporting configurations. Different CSI reporting configurations may correspond to different CSI resource configurations. Multiple CSI reporting configurations may correspond to the same CSI resource configuration. CSI reporting configurations may include semi-static CSI reporting configurations, dynamic CSI reporting configurations, and / or periodic CSI reporting configurations. A dynamic CSI reporting configuration may also be referred to as an aperiodic CSI reporting configuration. Different CSI reporting configurations may have different identifiers.

[0188] In some embodiments, each CSI report configuration may be associated with a CSI resource configuration. A CSI resource configuration may include information about one or more CSI resources for a terminal to send a CSI report.

[0189] In some embodiments, the CSI reporting configuration may include at least one of the following:

[0190] Time-frequency resource information of the measured reference signal;

[0191] Indication of the reported quantity.

[0192] Of course, the above is only an example of CSI report configuration, and the specific implementation is not limited to this example.

[0193] In some embodiments, multiple sub-configurations in a CSI reporting configuration may be sorted from small to large or from large to small according to the sub-configuration index numbers.

[0194] In some embodiments, multiple sub-configurations in a CSI reporting configuration may be sorted from high to low or from low to high according to the sub-configuration priority.

[0195] S2102: The terminal performs channel measurement to obtain a measurement result.

[0196] In some embodiments, the terminal performs CSI-Reference Signal (CSI-RS) measurement according to one or more sub-configurations to obtain a measurement result.

[0197] In some embodiments, the measurement results may include but are not limited to at least one of the following: Channel Quality Indication (CQI); Rank Indication (RI); Precoding Matrix Indicator (PMI); Signal to Interference plus Noise Ratio (SINR) of CSI-RS.

[0198] The channel measurement performed by the terminal may be performed in the order of the sub-configurations.

[0199] In some embodiments, the terminal may perform channel measurement based on all or none of the sub-configurations, for example, performing channel measurement on the first M sub-configurations with the highest measurement priority.

[0200] In some embodiments, the terminal may perform channel measurement according to a sub-configuration corresponding to a downlink transmission mode that the terminal can select to support.

[0201] In some embodiments, the sub-configuration received by the terminal may be a periodic sub-configuration, and the terminal periodically performs channel measurement according to the received one or more sub-configurations to obtain a measurement result.

[0202] In some embodiments, the sub-configuration received by the terminal may be a semi-static sub-configuration configured by the network device. In this case, the network device also receives a Media Access Control (MAC) Control Element (CE) sent by the network device.

[0203] In some embodiments, the MAC CE is used to activate or deactivate one or more sub-configurations received by the terminal.

[0204] In some embodiments, the MAC CE is used to activate or deactivate one or more sub-configurations in the activated CSI reporting configuration.

[0205] In some embodiments, the terminal performs channel measurement according to the activated sub-configuration in the activated CSI reporting configuration, obtains the measurement result of the activated sub-configuration, and constructs a sub-CSI report.

[0206] In some embodiments, the CSI reporting configuration received by the terminal may be a dynamic CSI reporting configuration. The terminal may also receive scheduling information sent by the network device. This scheduling information may be carried by downlink control information (DCI). Channel measurement is performed based on the scheduled subconfiguration in the subconfiguration of the CSI reporting configuration scheduled by the DCI to obtain a measurement result.

[0207] S2103: Determine the selected sub-configuration.

[0208] Exemplarily, step S2103 is an optional step.

[0209] In some embodiments, if there is one CSI reporting configuration mapped to one CSI resource, a sub-configuration is directly selected from the CSI reporting configuration to determine the selected sub-configuration.

[0210] The CSI resource here is the resource for sending the current UCI.

[0211] In some embodiments, the CSI resources may include a physical uplink control channel (PUCCH) and / or a physical uplink shared channel (PUSCH).

[0212] In some embodiments, when the CSI resources associated with each sub-configuration are insufficient to map all sub-CSI reports, it is necessary to select sub-CSI reports of some sub-configurations and map them to the UCI carried by the CSI resources.

[0213] In some embodiments, for example, in order to reduce the power consumption of the terminal during measurement, a sub-configuration may be selected before performing channel measurement, that is, part of the sub-configuration may be selected for channel measurement.

[0214] In some embodiments, in order to reduce signaling overhead, the terminal may also select a sub-configuration after completing the measurement, and then use UCI to carry the sub-CSI report of the selected sub-configuration.

[0215] In some embodiments, the terminal may determine the selected sub-configuration based on one or more of the priority of the sub-configuration in the CSI report configuration, the capability information of the terminal, and the load information of the terminal.

[0216] In some embodiments, the terminal may determine the priority of the CSI reporting configuration and / or sub-configuration according to a predefined calculation method.

[0217] In some embodiments, the capability information of the terminal may indicate the downlink reception-related capability of the terminal.

[0218] Exemplarily, the capability information of the terminal indicates at least one of the following:

[0219] Whether the terminal supports the spatial element for downlink transmission;

[0220] Downlink transmission power supported by the terminal;

[0221] Whether the terminal supports dynamic adjustment of downlink transmission power (spatial adaptation, SD).

[0222] In some embodiments, the load information of the terminal may include the load rate of the terminal and / or the load amount of the terminal.

[0223] In some embodiments, the terminal may also determine the sub-configuration based on parameters such as the quality of the currently detected wireless channel, and the specific implementation is not limited to the above examples.

[0224] In some embodiments, the selected sub-configuration is determined based on the priority of each sub-configuration in the CSI reporting configuration.

[0225] In some embodiments, if there are multiple CSI reporting configurations mapped to the same CSI resource, the selected CSI reporting configuration may be determined according to the priorities of the multiple CSI reporting configurations.

[0226] In some embodiments, when the number of bits required for the CSI reports of multiple CSI report configurations mapped to the same CSI resource is greater than the number of bits of the UCI carried by the CSI resource, the priorities of the multiple CSI report configurations mapped to the same CSI resource can be determined, and the CSI report of the CSI report configuration with a higher priority is selected to be mapped to the UCI. Only then will the CSI report be mapped to the CSI report configuration in the UCI be the selected CSI report configuration.

[0227] In one embodiment, the measurement results of the selected CSI reporting configuration are added to the UCI.

[0228] In some embodiments, the measurement results of the CSI reporting configuration that is not necessarily selected are not added to the UCI, that is, the terminal discards the measurement results of the CSI reporting configuration that is not selected.

[0229] In one embodiment, the selected CSI reporting configuration is less than or equal to the number of CSI reporting configurations in one CSI resource mapping.

[0230] In some embodiments, after the selected CSI reporting configuration is determined, the selected sub-configuration is determined according to the priority of the sub-configurations in the selected CSI reporting configuration.

[0231] In some embodiments, when the number of UCI bits cannot carry the measurement results of all subconfigurations of the selected CSI reporting configuration, the subconfiguration with the highest priority is determined as the selected subconfiguration based on the priority of the subconfigurations in the selected CSI reporting configuration.

[0232] In some embodiments, the selected subconfiguration may be a subconfiguration whose measurement results are selected to be added to the UCI.

[0233] In some embodiments, the number of subconfigurations selected in a CSI reporting configuration is less than or equal to the number of subconfigurations included in a CSI reporting configuration.

[0234] In some embodiments, the priority of a selected sub-configuration in a CSI reporting configuration is higher than the priority of an unselected sub-configuration in a CSI reporting configuration.

[0235] In some embodiments, priority may be indicated by a priority value, with a smaller priority value indicating a higher priority.

[0236] The above is an example in which the terminal determines the selected sub-configuration according to the priority of the sub-configuration, and the specific implementation is not limited to this example.

[0237] In some embodiments, the terminal may ignore the priorities of the various CSI reporting configurations and directly determine the selected sub-configuration based on the priorities of the various sub-configurations.

[0238] In some embodiments, the subconfiguration corresponding to the downlink transmission mode supported by the terminal may be selected as the subconfiguration.

[0239] In some embodiments, when the load rate of the terminal is greater than or equal to a specified threshold, one or more sub-configurations corresponding to the downlink transmission mode most frequently used by the terminal are selected as the selected sub-configurations.

[0240] In some embodiments, when the terminal's load rate is greater than or equal to a specified threshold, the X sub-configurations with the highest priority are selected as the sub-configurations. In some embodiments, when the terminal's load rate is less than a specified threshold, the Y sub-configurations with the highest priority are selected as the sub-configurations. In some embodiments, Y may be greater than X, and both X and Y are positive integers.

[0241] S2104: Send UCI.

[0242] In some embodiments, the terminal sends the UCI to the network device.

[0243] In some embodiments, UCI is transmitted to the network device on the CSI resources indicated by the CSI resource configuration associated with the CSI reporting configuration. In some embodiments, UCI is transmitted to the network device on the PUCCH resources indicated by the CSI resource configuration associated with the CSI reporting configuration. In some embodiments, UCI is transmitted to the network device on the PUSCH resources indicated by the CSI resource configuration associated with the CSI reporting configuration.

[0244] In some embodiments, a UCI includes one or more CSI reports (CSI-reports). A CSI report may include one or more sub-CSI reports. A sub-CSI report corresponds to a sub-configuration. A CSI report corresponds to a CSI report.

[0245] In some embodiments, one or more CSI reports in a UCI correspond to a selected subconfiguration in a selected CSI reporting configuration. Corresponding to the subconfiguration here may be a measurement result obtained by performing channel measurement according to the subconfiguration.

[0246] In one embodiment, a sub-CSI report may include one or more measurement results. The multiple measurement results may be associated with different reporting quantities, or associated with the same reporting quantity.

[0247] In one embodiment, the sub-CSI-report includes one or more measurement results, and the one or more measurement results correspond to the selected sub-configuration. That is, the measurement results included in the UCI are measurement results obtained by performing channel measurement according to the selected sub-configuration.

[0248] Among them, the measurement results or sub-CSI-report in the sub-CSI-report can have multiple mapping methods or arrangement methods, so that the network device can determine the correspondence between the sub-CSI-report and the sub-configuration (sub-csi-report-configuration or subconfiguration), and then determine the downlink channel estimation of different downlink transmission modes.

[0249] For ease of explanation, the following text takes the CSI-report without the two-part CSI-report transmission method as an example. The information processing method provided in the embodiments of the present disclosure is also applicable to the two-part CSI-report method.

[0250] The mapping order or arrangement may include a first order and / or a second order.

[0251] In some embodiments, the first order is related to the sub-configuration. In some embodiments, the first order is used to arrange or map sub-CSI-reports or measurement results within a CSI-report.

[0252] For example, the first order is determined based on the index number of the sub-configuration, or in other words, the first order corresponds to the index number of the sub-configuration. For another example, the first order is determined based on the priority of the sub-configuration, or in other words, the first order corresponds to the priority of the sub-configuration.

[0253] In some embodiments, the first order includes one of the following:

[0254] The priorities of multiple sub-CSI-reports are from high to low;

[0255] The priorities of multiple sub-CSI-reports are from low to high;

[0256] The index numbers of multiple sub-CSI-reports are from large to small;

[0257] The index numbers of the sub-CSI-reports are from small to large.

[0258] The priority of the sub-CSI-report here may be the priority of the sub-configuration corresponding to the sub-CSI-report.

[0259] The index number of the sub-CSI-report here may be the index of the sub-configuration corresponding to the sub-CSI-report.

[0260] In some embodiments, the first order may be related to the priority of the selected sub-configuration.

[0261] In some embodiments, the first order may be related to the size of the index number of the selected sub-configuration.

[0262] In some embodiments, the first order may be an order of priority from high to low for the selected sub-configurations.

[0263] In some embodiments, the first order may be an order from low to high priority of the selected sub-configurations.

[0264] In some embodiments, the first order may be an order from largest to smallest index number of the selected sub-configuration.

[0265] In some embodiments, the first order may be an ascending order of the index numbers of the selected sub-configurations.

[0266] In some embodiments, the sub-CSI reports of multiple sub-configurations of the same selected CSI reporting configuration are arranged in the UCI from largest to smallest according to the index numbers of the multiple sub-configurations.

[0267] In some embodiments, sub-CSI reports of multiple sub-configurations of the same CSI reporting configuration are arranged in the UCI according to the priorities of the multiple sub-configurations from low to high.

[0268] In some embodiments, the first order is determined based on the CSI reporting configuration.

[0269] For example, when one UCI includes CSI reports corresponding to two or more CSI report configurations, the first order is determined based on the priority of the CSI-report, or the first order is determined based on the index number of the CSI-report.

[0270] A sub-CSI-report belongs to a CSI-report.

[0271] The UCI includes one or more CSI-reports, wherein a sub-CSI-report belongs to one CSI-report.

[0272] In some embodiments, the first order is based on the priority determination of the CSI-reports and includes: the priorities of the multiple CSI-reports are from high to low, or the priorities of the multiple CSI-reports are from high to low.

[0273] In some embodiments, the first order is determined based on the index number of the CSI-report, including: the index numbers of the multiple CSI-reports are from large to small, or the index numbers of the multiple CSI-reports are from small to large.

[0274] In this way, before mapping the sub-CSI-report corresponding to the sub-configuration in the UCI, the mapping order of multiple CSI-reports is determined first, and then the sub-CSI-report corresponding to the sub-configuration in one CSI-report is mapped.

[0275] In some embodiments, the third order is related to the sub-configuration. In some embodiments, the third order is used to determine the mapping of measurement results in sub-CSI reports of different sub-configurations.

[0276] In some embodiments, the first order includes one of the following:

[0277] The index numbers of the multiple sub-configurations corresponding to the measurement results are from large to small;

[0278] The index numbers of the multiple sub-configurations corresponding to the measurement results are from small to large;

[0279] The priorities of multiple sub-configurations corresponding to the measurement results are from high to low;

[0280] The priorities of the multiple sub-configurations corresponding to the measurement results are from low to high.

[0281] The sub-CSI report corresponding to one sub-configuration may include one or more measurement results. For example, the sub-CSI report may include multiple measurement results such as PMI, RI and / or CQI.

[0282] In some embodiments, the same measurement results of multiple sub-configurations can be mapped to UCIs based on the sub-configuration index and / or priority. For example, the importance of PMI may be higher than that of RI and / or CQI. In this case, the PMIs of all selected sub-configurations can be preferentially mapped to UCIs. When mapping multiple PMIs, they can be sorted and mapped based on the index and / or priority of the selected sub-configurations. The sorting and mapping method can be from large to small index number, from small to large index number, from high to low priority, or from low to high priority.

[0283] In some embodiments, measurement results of multiple sub-configurations of the same selected CSI reporting configuration are arranged in the UCI according to the index numbers of the multiple sub-configurations from largest to smallest.

[0284] In some embodiments, measurement results of multiple sub-configurations of the same CSI reporting configuration are arranged in the UCI according to the priorities of the multiple sub-configurations from low to high.

[0285] In some embodiments, the UCI may include a first result and a second result.

[0286] In some embodiments, the first result may be a measurement result related to the common reporting quantity among the measurement results of multiple sub-configurations of a selected CSI reporting configuration.

[0287] In some embodiments, the second result may be a measurement result that is not related to the common reporting quantity among the measurement results of multiple sub-configurations of a selected CSI reporting configuration.

[0288] In some embodiments, the common reporting amount may be a reporting amount configured for multiple sub-configurations. For example, if the selected sub-configuration 1 and sub-configuration 2 both have reporting amounts for the precoding matrix index, then the reporting amount for the precoding matrix index is the common reporting amount.

[0289] In some embodiments, the reported amount may be a measurement object indicated by the CSI report configuration that requires the measurement value to be carried in the CSI report. The reported amount may also be a measurement object indicated by the sub-configuration that requires the measurement value to be carried in the sub-CSI report.

[0290] In some embodiments, a common reporting quantity may be a reporting quantity directly included in a CSI reporting configuration and not specific to any sub-configuration. For example, if reporting quantity A is included in a CSI reporting configuration but not in any sub-configuration, and the measurement results of any sub-configuration in the CSI reporting configuration are selected for reporting via UCI, the measurement results of reporting quantity A will be reported along with the measurement results of the independent reporting quantities of that sub-configuration. This reporting quantity A is the common reporting quantity.

[0291] In some embodiments, a possible situation is that the sub-CSI-reports corresponding to multiple sub-configurations only contain measurement results related to the common reporting quantity. In this case, there may be only the first result. In this case, the first result can be directly mapped to the UCI. The order of mapping the measurement results corresponding to different sub-configurations of a common reporting quantity to the UCI can refer to the third order. For example, the measurement results of different common reporting quantities can be mapped to the UCI according to the importance or priority of the reporting quantity, for example, from high to low priority, from low to high, from large to small importance, or from small to large importance. Importance can be determined by whether the subsequent encoding and decoding of service data by the terminal and network equipment is indispensable. For example, in this case, the importance of PMI may be higher than the importance of RI. The priority of the common reporting quantity can be pre-configured.

[0292] In some embodiments, the measurement result not related to the common reporting amount may be: a measurement result related to the dedicated reporting amount of the selected sub-configuration.

[0293] In some embodiments, the first result related to the publicly reported quantity may include a measurement result of the publicly reported quantity.

[0294] In some embodiments, the second result not related to the public reporting amount may include a measurement result of the non-public reporting amount. For example, the measurement result of the non-public reporting amount may include a measurement result of the selected sub-configuration-specific reporting amount.

[0295] In some embodiments, the first result is ranked before the second result in the UCI.

[0296] In some embodiments, the second result is placed in the UCI before the first result.

[0297] For example, if the bit is ranked higher in the UCI, it is mapped to the bit ranked higher in the UCI, and if the bit is ranked lower in the UCI, it is mapped to the bit ranked lower in the UCI.

[0298] The present disclosure provides an information processing method, which can be executed by a terminal, including:

[0299] Send a CSI report according to a predefined order of mapping the channel state information CSI to the bit sequence in the uplink control information UCI; wherein the CSI report includes: a sub-CSI report associated with a sub-configuration in the CSI report configuration, wherein the CSI is carried in the UCI.

[0300] That is, the terminal sends a CSI report via UCI, and the CSI report contains sub-CSI reports corresponding to the sub-configuration. The mapping relationship between the CSI report and the UCI bit sequence is performed in a predefined order.

[0301] Exemplarily, the predefined order includes at least one of the following:

[0302] A first order is used for mapping CSI associated with a subconfiguration of the CSI reporting configuration and the bit sequence;

[0303] or,

[0304] The second order is used for mapping the CSI associated with multiple sub-configurations of the CSI reporting configuration and the bit sequence.

[0305] Illustratively, the first sequence may have at least one of the following characteristics:

[0306] A mapping order between the bit sequence and the sub-CSI reports associated with the multiple sub-configurations of the same CSI reporting configuration is related to the index size of the sub-configurations;

[0307] The mapping order between the bit sequence and the sub-CSI reports associated with the multiple sub-configurations of the same CSI report configuration is related to the size of the priority parameter of the sub-configuration.

[0308] Furthermore, mapping the sub-CSI reports in the CSI report to the UCI based on the first order may adopt at least one of the following methods:

[0309] The mapping order between the bit sequence and the CSI associated with the multiple subconfigurations of the same CSI reporting configuration is: the indexes of the subconfigurations corresponding to the bit sequence from front to back are from large to small, or the indexes of the subconfigurations corresponding to the bit sequence from front to back are from small to large;

[0310] The mapping order between the bit sequence and the sub-CSI reports associated with multiple sub-configurations of the same CSI report configuration is: the bit sequence corresponds to the priority parameters of the sub-configurations from small to large from front to back, or the bit sequence corresponds to the priority parameters of the sub-configurations from large to small from front to back.

[0311] Further, mapping the CSI report to the UCI based on the second order may include: the mapping order between the bit sequence and the sub-CSI reports associated with the sub-configurations of the multiple CSI report configurations is related to the priority parameter size of the CSI report configuration, or the mapping order between the bit sequence and the sub-CSI reports associated with the sub-configurations of the multiple CSI report configurations is related to the index number size of the CSI report configuration.

[0312] In some embodiments, the size of the priority parameter of the CSI reporting configuration and / or sub-configuration is negatively correlated with the level of the priority.

[0313] In some embodiments, the mapping order between the bit sequence and the sub-CSI reports associated with the sub-configurations of the multiple CSI reporting configurations is related to the size of the priority parameter of the CSI reporting configuration, including:

[0314] The mapping order between the bit sequence and the sub-CSI reports associated with the sub-configurations of the multiple CSI report configurations is: the bit sequence corresponds to the priority parameters of the multiple CSI report configurations from small to large from front to back, or the bit sequence corresponds to the priority parameters of the multiple CSI report configurations from large to small from front to back.

[0315] In some embodiments, the CSI report includes a measurement result of at least one common reporting quantity of the CSI reporting configuration, the measurement result of the common reporting quantity is sent based on the CSI corresponding to the CSI reporting configuration, and / or,

[0316] The CSI report includes a measurement result of at least one non-public reporting quantity of the CSI reporting configuration corresponding to at least one sub-configuration, and the measurement result of the non-public reporting quantity corresponding to a sub-configuration is sent based on the sub-CSI report corresponding to the sub-configuration.

[0317] In some embodiments, different sub-configurations correspond to the same public reporting amount; the sub-configurations correspond to non-public reporting amounts.

[0318] As shown in FIG3 , an embodiment of the present disclosure provides an information processing method executed by a terminal. The method may include:

[0319] S3101: Receive one or more CSI report configurations.

[0320] In some embodiments, the terminal receives a CSI report configuration sent by a network device.

[0321] In some embodiments, the CSI reporting configuration includes one or more sub-configurations, wherein the sub-configurations correspond to downlink transmission modes of the network device.

[0322] In some embodiments, different downlink transmission modes may correspond to different spatial elements and / or transmit powers of the network device.

[0326] In some embodiments, channel measurement is performed according to the CSI reporting configuration to obtain a measurement result.

[0327] In some embodiments, status measurement is performed according to a sub-configuration of the CSI reporting configuration to obtain a measurement result.

[0331] In some embodiments, the terminal may determine the selected CSI reporting configuration and the selected sub-configuration according to the priority of the CSI reporting configuration and the priority of each sub-configuration in the CSI reporting configuration.

[0332] In some embodiments, the optional method of S3103 can refer to any optional method of S2103 in the corresponding example of Figure 2.

[0333] S3104: Send UCI.

[0334] In some embodiments, the optional method of S3104 can refer to any optional method of S2104 in the corresponding embodiment of Figure 2.

[0335] In some embodiments, the terminal sends the UCI to the network device.

[0336] In some embodiments, the UCI is sent to the network device on the CSI resources indicated by the CSI resource configuration associated with the CSI reporting configuration.

[0337] In some embodiments, the UCI is sent to the network device on a PUCCH resource indicated by a CSI resource configuration associated with the CSI reporting configuration.

[0338] In some embodiments, the UCI is sent to the network device on a PUSCH resource indicated by a CSI resource configuration associated with the CSI reporting configuration.

[0339] In some embodiments, the UCI includes one or more CSI reports (CSI-reports).

[0340] In some embodiments, one or more CSI reports in the UCI correspond to a selected subconfiguration in the selected CSI reporting configuration. Corresponding to the subconfiguration here may be a measurement result obtained by performing channel measurement according to the subconfiguration.

[0341] In one embodiment, a CSI report may include one or more measurement results. The multiple measurement results may be associated with different reporting quantities, or associated with the same reporting quantity.

[0342] In one embodiment, the CSI-report includes one or more measurement results, and the one or more measurement results correspond to the selected sub-configuration. That is, the measurement results included in the UCI are measurement results obtained by performing channel measurement according to the selected sub-configuration.

[0343] The terminal sends UCI, and the network device receives UCI.

[0344] In one embodiment, the CSI report carried by the UCI corresponds to multiple sub-CSI report configurations, and the measurement results of the multiple sub-CSI reports are arranged in the UCI in a first order.

[0345] In some embodiments, the first order may be related to the priority of the selected sub-configuration.

[0346] In some embodiments, the first order may be related to the size of the index number of the selected sub-configuration.

[0347] In some embodiments, the first order may be an order of priority from high to low for the selected sub-configurations.

[0348] In some embodiments, the first order may be an order from low to high priority of the selected sub-configurations.

[0349] In some embodiments, the first order may be an order from largest to smallest index number of the selected sub-configuration.

[0350] In some embodiments, the first order may be an ascending order of the index numbers of the selected sub-configurations.

[0351] In some embodiments, the first order is determined based on the priority of the CSI-report, or the first order is determined based on the index number of the CSI-report.

[0352] In some embodiments, UCI includes one or more CSI-reports, wherein a sub-CSI-report belongs to one CSI-report.

[0353] In some embodiments, the first order is based on the priority determination of the CSI-report and includes: the priority of the plurality of CSI-reports is from high to low, or the priority of the plurality of CSI-reports is from high to low;

[0354] The first order is determined based on the index number of the CSI-report, including: the index numbers of multiple CSI-reports are from large to small, or the index numbers of multiple CSI-reports are from small to large.

[0355] In one embodiment, the CSI report carried by the UCI corresponds to the same selected CSI report configuration, and the measurement results of the selected sub-configuration may also be arranged in the second order.

[0356] In some embodiments, measurement results of multiple sub-configurations of the same selected CSI reporting configuration are arranged in the UCI according to the index numbers of the multiple sub-configurations from largest to smallest.

[0357] In some embodiments, measurement results of multiple sub-configurations of the same CSI reporting configuration are arranged in the UCI according to the priorities of the multiple sub-configurations from low to high.

[0358] In some embodiments, the UCI may include a first result and a second result.

[0359] In some embodiments, the first result may be a measurement result related to the common reporting quantity among the measurement results of multiple sub-configurations of a selected CSI reporting configuration.

[0360] In some embodiments, the second result may be a measurement result that is not related to the common reporting quantity among the measurement results of multiple sub-configurations of a selected CSI reporting configuration.

[0361] In some embodiments, the first result is ranked before the second result in the UCI.

[0362] In some embodiments, the second result is placed in the UCI before the first result.

[0363] For example, if the bit is ranked higher in the UCI, it is mapped to the bit ranked higher in the UCI, and if the bit is ranked lower in the UCI, it is mapped to the bit ranked lower in the UCI.

[0364] In some embodiments, a possible situation is that the sub-CSI-reports corresponding to multiple sub-configurations only contain measurement results related to the common reporting quantity. In this case, there may be only the first result. In this case, the first result can be directly mapped to the UCI. The order in which the measurement results corresponding to different sub-configurations of a common reporting quantity are mapped to the UCI can refer to the second order. For example, the measurement results of different common reporting quantities can be mapped to the UCI according to the importance or priority of the reporting quantity, for example, from high to low priority, from low to high, from large to small importance, or from small to large importance. Importance can be determined by whether the subsequent encoding and decoding of service data by the terminal and network equipment is indispensable. For example, in this case, the importance of PMI may be higher than the importance of RI. The priority of the common reporting quantity can be pre-configured.

[0365] It is worth noting that an embodiment may include steps S3101, S3102, and S3104, that is, S3103 is an optional step. For example, channel measurement is performed according to the sub-configuration in each CSI reporting configuration to obtain a measurement result, and the measurement result is sent on the UCI.

[0366] It is worth noting that one embodiment may include steps S3102, S3103, and S3104, i.e., step S3101 is optional. For example, if the terminal has pre-received multiple CSI reporting configurations or is aware of each CSI reporting configuration according to a protocol agreement, the terminal may not receive the CSI reporting configuration from the network side or may not receive the CSI reporting configuration from the network side every time.

[0367] In some embodiments, the message structure of the UCI may be any one of those shown in FIG. 5A to FIG. 5C .

[0368] As shown in Figure 5A, UCI is used to carry sub-CSI reports of multiple sub-configurations of one or more CSI reporting configurations. The sub-CSI reports of multiple sub-configurations in the same CSI reporting configuration may include one or more measurement results. The sub-CSI reports may be indexed from small to large in the order of the low bit (a0) to the high bit (a1) of the UCI bit sequence. A-1 ) bitmap. In FIG5A , sub-CSI reports belonging to different CSI reports are marked with different shades of gray. For example, the first sub-CSI report (sub-CSI1) and the last sub-CSI report belong to different CSI reports.

[0369] As shown in Figure 5B, UCI is used to carry sub-CSI reports of multiple sub-configurations of multiple CSI report configurations. Multiple sub-CSI reports can be mapped from the low bits of UCI to the high bits according to the priority of the CSI report configuration or the size of the index. The measurement results of the sub-configurations of the same CSI report configuration can be mapped from the low bits (a0) to the high bits (a1) of the bit sequence of the sub-CSI report and the UCI according to the size of the sub-configuration index number or the priority. A-1 ) bitmap.

[0370] As shown in Figure 5C , the UCI may include: measurement results of the commonly reported quantities in the sub-CSI reports of multiple sub-configurations (i.e., first results) and measurement results of each sub-configuration (i.e., second results). The first results may be mapped preferentially to the lower-order bits of the UCI, followed by the second results. If the UCI needs to carry measurement results for multiple CSI reporting configurations, this may be determined based on the index number size and / or priority level of the CSI reporting configurations.

[0371] The terminal and network device can predefine the mapping order in which the measurement results of the CSI reporting configuration and / or sub-configuration are mapped to the UCI. In this way, after the terminal sends the UCI, the network device correctly decodes the UCI according to the predefined mapping order. Using this predefined mapping order can minimize the bit overhead of the UCI.

[0372] In some embodiments, the UCI further comprises at least one of the following:

[0373] The first field is used to indicate the order of one or more CSI-reports in the UCI;

[0374] The second field is used to indicate the identifier of the CSI report configuration and / or the identifier of the corresponding sub-configuration corresponding to one or more CSI-reports;

[0375] The third field is used to indicate an unselected CSI reporting configuration;

[0376] The fourth field is used to indicate unselected sub-configuration.

[0377] By carrying any of the above fields, network devices can be assisted in fast decoding.

[0378] The present disclosure provides an information processing method, which can be executed by a terminal, including:

[0379] A network device receives uplink control information (UCI) sent by a terminal, wherein the UCI includes a channel state information (CSI) report determined based on a predefined order; the CSI report includes a sub-CSI report associated with a sub-configuration in a CSI report configuration, and the predefined order is a mapping order between the UCI bit sequence and the CSI.

[0380] That is, the terminal sends a CSI report via UCI, which contains sub-CSI reports corresponding to the sub-configuration. The mapping relationship between the CSI report and the UCI bit sequence is performed in a predefined order. At this time, the network device will receive the corresponding UCI.

[0381] Exemplarily, the predefined order includes at least one of the following:

[0382] A first order is used for mapping CSI associated with a subconfiguration of the CSI reporting configuration and the bit sequence;

[0383] or,

[0384] The second order is used for mapping the CSI associated with multiple sub-configurations of the CSI reporting configuration and the bit sequence.

[0385] Illustratively, the first sequence may have at least one of the following characteristics:

[0387] The mapping order between the bit sequence and the sub-CSI reports associated with the multiple sub-configurations of the same CSI report configuration is related to the size of the priority parameter of the sub-configuration.

[0388] Furthermore, mapping the sub-CSI reports in the CSI report to the UCI based on the first order may adopt at least one of the following methods:

[0389] The mapping order between the bit sequence and the CSI associated with the multiple subconfigurations of the same CSI reporting configuration is: the indexes of the subconfigurations corresponding to the bit sequence from front to back are from large to small, or the indexes of the subconfigurations corresponding to the bit sequence from front to back are from small to large;

[0390] The mapping order between the bit sequence and the sub-CSI reports associated with multiple sub-configurations of the same CSI report configuration is: the bit sequence corresponds to the priority parameters of the sub-configurations from small to large from front to back, or the bit sequence corresponds to the priority parameters of the sub-configurations from large to small from front to back.

[0391] Further, mapping the CSI report to the UCI based on the second order may include: the mapping order between the bit sequence and the sub-CSI reports associated with the sub-configurations of the multiple CSI report configurations is related to the priority parameter size of the CSI report configuration, or the mapping order between the bit sequence and the sub-CSI reports associated with the sub-configurations of the multiple CSI report configurations is related to the index number size of the CSI report configuration.

[0392] In some embodiments, the size of the priority parameter of the CSI reporting configuration and / or sub-configuration is negatively correlated with the level of the priority.

[0393] In some embodiments, the mapping order between the bit sequence and the sub-CSI reports associated with the sub-configurations of the multiple CSI reporting configurations is related to the size of the priority parameter of the CSI reporting configuration, including:

[0394] The mapping order between the bit sequence and the sub-CSI reports associated with the sub-configurations of the multiple CSI report configurations is: the bit sequence corresponds to the priority parameters of the multiple CSI report configurations from small to large from front to back, or the bit sequence corresponds to the priority parameters of the multiple CSI report configurations from large to small from front to back.

[0395] In some embodiments, the CSI report includes a measurement result of at least one common reporting quantity of the CSI reporting configuration, the measurement result of the common reporting quantity is sent based on the CSI corresponding to the CSI reporting configuration, and / or,

[0396] The CSI report includes a measurement result of at least one non-public reporting quantity of the CSI reporting configuration corresponding to at least one sub-configuration, and the measurement result of the non-public reporting quantity corresponding to a sub-configuration is sent based on the sub-CSI report corresponding to the sub-configuration.

[0397] In some embodiments, different sub-configurations correspond to the same public reporting amount; the sub-configurations correspond to non-public reporting amounts.

[0398] As shown in FIG4 , an embodiment of the present disclosure provides an information processing method, which is executed by a network device. The method may include:

[0399] S4101: Send CSI report configuration.

[0400] In some embodiments, the network device may include an access network device, which may include but is not limited to a serving base station of the terminal.

[0418] For example, the uplink data structure may refer to the description of UCI in the embodiment corresponding to FIG. 2 , or may refer to FIG. 5A to FIG. 5C .

[0419] In some embodiments, the plurality of sub-CSI-reports are arranged in a UCI in a first order; the first order corresponds to the sub-configuration; the first order is used to determine the ordering of the sub-CSI-reports in the UCI;

[0420] The first order includes:

[0421] The priorities of multiple sub-CSI-reports are from high to low, or,

[0422] Priority of multiple sub-CSI-reports from low to high, or

[0423] The index numbers of multiple sub-CSI-reports are from large to small, or,

[0424] The index numbers of multiple sub-CSI-reports are from small to large, or,

[0425] The first order is determined based on the priority of the CSI-report, or,

[0426] The first order is determined based on the index number of the CSI-report,

[0427] The UCI includes one or more CSI-reports, wherein a sub-CSI-report belongs to one CSI-report.

[0429] The third order includes:

[0430] The index numbers of the multiple sub-configurations corresponding to the measurement results are from large to small, or,

[0431] The index numbers of the multiple sub-configurations corresponding to the measurement results are from small to large, or,

[0432] The priority of the measurement results is from high to low, or,

[0433] The priority of the measurement results is from low to high, or,

[0434] The measurement results of multiple sub-configurations of the same selected CSI reporting configuration include a first result related to the common reporting quantity and a second result not related to the common reporting quantity; the first result is sorted before the second result in the UCI, or the second result is sorted before the first result in the UCI.

[0435] When a CSI report configuration contains multiple reporting sub-configurations, a UCI bit mapping scheme with the sub-CSI corresponding to the sub-configuration as the granularity is designed to improve terminal CSI reporting efficiency and achieve consistent understanding between the terminal and the base station.

[0436] Terminal side:

[0437] Under the condition that a CSI report config contains multiple reporting sub-configurations, the terminal determines the mapping rule of CSI resources and performs CSI reporting.

[0438] CSI mapping (mapping) with sub-CSI report as the granularity is introduced. The sub-CSI report corresponds to a specific CSI, and the CSI includes one or more sub-CSI reports.

[0439] A first order is defined, and the terminal determines a mapping order of at least one sub-CSI report corresponding to the same CSI report based on the first order.

[0440] Exemplarily, the sub-configuration index numbers corresponding to the sub-CSI reports correspond one to one in ascending order (or from large to small).

[0441] Exemplarily, priority parameters corresponding to the sub-CSI reports correspond one to one in an ascending order (or a descending order).

[0442] A second order is defined, and the terminal determines a mapping order of sub-CSI reports corresponding to different CSI reports based on the second order.

[0443] Exemplarily, under the condition that the CSI priority value corresponding to the first sub-CSI report is smaller than the CSI priority value corresponding to the second sub-CSI report, the mapping order of the first sub-CSI report is superior to that of the second sub-CSI report.

[0444] If the corresponding reporting quantity (quantity or metric) is reported based on a sub-configuration, the terminal reports based on the sub-CSI report corresponding to the sub-configuration;

[0445] If the corresponding reporting amount is reported based on the CSI reporting configuration, that is, the reporting amounts of different sub-configurations corresponding to the same CSI reporting configuration are the same, the terminal reports based on the CSI reporting configuration;

[0446] Base station side:

[0447] Under the condition that a CSI reporting configuration includes multiple reporting sub-configurations, the base station determines a mapping rule for the CSI bits and receives a CSI reporting result from the terminal.

[0448] CSI mapping with sub-CSI reports as the granularity is introduced. A sub-CSI report corresponds to a specific CSI, and CSI contains one or more sub-CSI reports:

[0449] A first order is defined, and the base station determines a mapping order of at least one sub-CSI report corresponding to the same CSI report based on the first order;

[0450] Exemplarily, the sub-configuration index numbers corresponding to the sub-CSI reports correspond one to one in ascending order (or from large to small).

[0451] Exemplarily, priority parameters corresponding to the sub-CSI reports correspond one to one in an ascending order (or a descending order).

[0452] A second order is defined, and the base station determines a mapping order of sub-CSI reports corresponding to different CSI reports based on the second order.

[0453] Exemplarily, under the condition that the CSI priority value corresponding to the first sub-CSI report is smaller than the CSI priority value corresponding to the second sub-CSI report, the mapping order of the first sub-CSI report is superior to that of the second sub-CSI report.

[0454] If the corresponding reporting quantity is reported based on the sub-configuration, the terminal sends a sub-CSI report based on the sub-configuration.

[0455] If the corresponding reporting metric is reported based on the CSI reporting configuration, that is, the terminal reports based on the CSI reporting configuration, the common reporting metric may be sent by the terminal based on the CSI report.

[0456] The terminal supports the Network Energy Saving (NES) feature. To support measurement reporting of multiple spatial patterns (SDs) and / or multiple power standards, NES supports sub-CSI reporting of multiple sub-configurations for the same CSI report configuration. Compared to one CSI report configuration corresponding to one CSI, one CSI report configuration associated with NES corresponds to multiple sub-configurations, and each sub-configuration corresponds to a sub-CSI report, which can effectively improve the performance of dynamic CSI measurement reporting.

[0457] Under the condition of configuring multiple sub-configurations, the embodiments of the present disclosure primarily consider the sub-configuration-based configuration of the first reported quantity in some specific CSI reporting quantities. For example, different sub-configurations correspond to different first reported quantities (CSI quantities), and / or under the condition that the specific reported quantity (assuming it is the second reported quantity) is based on the CSI report configuration, for example, the second reported quantities corresponding to different sub-configurations are the same, designing rules to determine the resource mapping method for different CSI quantities.

[0458] The embodiment of the present disclosure takes the UCI mapping of CSI on PUCCH as an example to illustrate the solution of the present invention. Other application scenarios are also within the scope of the solution of the present invention and will not be described in detail here.

[0459] Implementation 1: For a CSI report corresponding to a CSI report, which includes multiple sub-CSI reports corresponding to sub-configurations, the mapping order between the sub-CSI reports and the UCI bits is shown in FIG5C .

[0460] 1.1: In one possible implementation, if a second reporting metric exists, the second reporting metric corresponds to a different sub-configuration of the same CSI report and is reported based on CSI report #1, i.e., it corresponds to the common metric shown in FIG5C . If the second reporting metric does not exist, or the second reporting metric is still reported based on a sub-configuration, CSI report #1 shown in FIG5C does not exist, or the percentage of the second reporting metric is 0.

[0461] 1.2: In one possible implementation, there is a first reporting amount, and the first reporting amount corresponding to different sub-configurations is different, and / or the first reporting amount is reported based on the sub-configuration. Then, the first reporting amount is included in sub-CSI#1…sub-CSI Ni shown in Figure 5C, corresponding to sub-configuration#1,….sub-config#Ni; wherein Ni is the number of sub-configurations actually configured in CSI report#i, or Ni is the maximum number of sub-configurations that can be configured in CSI report#i.

[0462] 1.3: In one possible implementation, sub-CSI reports corresponding to different sub-configurations corresponding to the same CSI report are mapped one-to-one with UCI bits based on a first order. For example, the sub-configuration index numbers corresponding to the sub-CSI are mapped one-to-one with the UCI bits in an ascending order (from large to small); the sub-configuration index numbers are based on a higher-layer parameter configuration;

[0463] 1.4: A possible implementation manner is that the sub-CSI reports corresponding to different sub-configurations corresponding to the same CSI report are mapped one-to-one with the UCI bits based on the first order. Exemplarily, the order of the priorities corresponding to the sub-CSI reports from high to low (from low to high) is mapped one-to-one with the order of the UCI bits from low to high. The priorities corresponding to the sub-CSI reports are based on a predefined method or a high-layer parameter configuration. Exemplarily, the priorities corresponding to the sub-CSI reports are positively correlated with the index numbers corresponding to the sub-configurations corresponding to the sub-CSI reports. That is, the higher the priority corresponding to the sub-CSI report, the higher the priority of the sub-CSI report. The priority may be indicated by an index or value of the priority. The larger the index or value of the priority, the lower the priority, i.e., a negative correlation.

[0464] 1.5: In one possible implementation, sub-CSI reports corresponding to different sub-configurations corresponding to different CSI reports are mapped one-to-one to UCI bits based on the second order. For example, if the priority value of the CSI report corresponding to the first sub-CSI report is lower than the priority value of the CSI report corresponding to the second sub-CSI report, the first sub-CSI report is mapped prior to the second sub-CSI report. As shown in Figure 5C, any sub-CSI report corresponding to CSI report #1 is mapped prior to any sub-CSI report corresponding to CSI report #2.

[0465] In the embodiments of the present disclosure, some or all of the steps and their optional implementations may be arbitrarily combined with some or all of the steps in other embodiments, or may be arbitrarily combined with the optional implementations of other embodiments.

[0466] In the embodiments of the present disclosure, some or all of the steps and their optional implementations may be arbitrarily combined with some or all of the steps in other embodiments, or may be arbitrarily combined with the optional implementations of other embodiments.

For example, an apparatus is provided, comprising units or modules for implementing each step performed by a terminal in any of the above methods. For another example, another apparatus is provided, comprising units or modules for implementing each step performed by a network device (e.g., an access network device or a core network device) in any of the above methods.

[0468] It should be understood that the division of the various units or modules in the above devices is merely a division of logical functions. In actual implementation, they may be fully or partially integrated into a physical entity, or they may be physically separated. In addition, the units or modules in the device may be implemented in the form of a processor calling software: for example, the device includes a processor, the processor is connected to a memory, and the memory stores instructions. The processor calls the instructions stored in the memory to implement any of the above methods or implement the functions of the various units or modules of the above devices, wherein the processor is, for example, a general-purpose processor, such as a central processing unit (CPU) or a microprocessor, and the memory is a memory within the device or a memory outside the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits, and the functions of some or all of the units or modules can be realized by designing the hardware circuits. The above-mentioned hardware circuits can be understood as one or more processors; for example, in one implementation, the above-mentioned hardware circuit is an application-specific integrated circuit (ASIC), which realizes the functions of some or all of the above units or modules by designing the logical relationship of the components in the circuit; for example, in another implementation, the above-mentioned hardware circuit can be realized by a programmable logic device (PLD). Taking a field programmable gate array (FPGA) as an example, it can include a large number of logic gate circuits, and the connection relationship between the logic gate circuits is configured by configuring the configuration file, thereby realizing the functions of some or all of the above units or modules. All units or modules of the above devices can be realized in the form of software called by the processor, or in the form of hardware circuits, or in part by the form of software called by the processor, and the rest by hardware circuits.

[0469] In the embodiments of the present disclosure, a processor is a circuit with signal processing capabilities. In one implementation, the processor can be a circuit with instruction reading and execution capabilities, such as a central processing unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationship of a hardware circuit. The logical relationship of the above-mentioned hardware circuit is fixed or reconfigurable. For example, the processor is a hardware circuit implemented by an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document to implement the hardware circuit configuration can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. In addition, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a neural network processing unit (NPU), a tensor processing unit (TPU), a deep learning processing unit (DPU), etc.
