Description

[Technical Field]

[0001] This invention relates to the technology field of communications. [Background technology]

[0002] As a crucial component in building new global infrastructure, 5G communication networks have experienced rapid growth worldwide in recent years. With the widespread adoption of 5G across various industries and its application in a wide range of regions, there is a demand for extremely high data rates and high-density networks to support more advanced services. As a result, power consumption of 5G equipment is increasing as more antennas, wider bandwidth, and more frequency bands are used.

[0003] According to data statistics from telecommunications carriers, the average power consumption of a single 5G base station is more than three times that of an LTE base station. Approximately half of the cost for telecommunications carriers deploying 5G networks is electricity. More importantly, 5G base stations still have a considerable power consumption overhead even during periods of low traffic / service activity. Therefore, energy conservation in the network is of great importance for improving environmental sustainability, reducing environmental impact (e.g., reducing greenhouse gas emissions), and lowering operating costs. Energy conservation in 5G networks is a challenge that needs to be addressed.

[0004] To achieve energy savings in networks, Rel-18 includes an agenda item on network energy saving for the study of various energy-saving technologies. In the discussions, network energy-saving technologies can be categorized into types such as time-domain, frequency-domain, spatial-domain, and energy-domain energy saving. Examples of spatial-domain energy saving include dynamic adjustment of antenna count, energy-domain energy saving includes dynamic adjustment of data transmission power, and time-domain energy saving includes the introduction of cell DTX / DRX technology. By utilizing various energy-saving technologies, significant energy savings can be achieved in network equipment.

[0005] Note that the introduction of the above background art is for clearly and completely explaining the technical solution of the present invention and for facilitating understanding by those skilled in the art. These technical solutions are described in the background art of the present invention and shall not be construed as well-known to those skilled in the art.

Summary of the Invention

Problems to be Solved by the Invention

[0006] However, the inventor has discovered the following. That is, it may have an adverse effect in some scenarios where wireless communication is applied (for example, the power-saving mode). For example, when the network device dynamically adjusts the number of antennas or the transmission power, a change in the corresponding channel may occur. Therefore, the channel state information (CSI) report from the terminal device may be inaccurate or untimely, and ultimately may affect the transmission performance.

[0007] When the network device adjusts the antenna settings (for example, for the purpose of power saving), the network device triggers / instructs / activates the terminal device to report N pieces of CSI out of L pieces of CSI, where N <L. How the network device makes a CSI instruction to cause the terminal device to transmit a multi-CSI CSI report is currently an important problem that needs to be solved.

[0028] The following describes a scenario of an embodiment of the present invention through examples, but the present invention is not limited thereto.

[0029] Figure 1 shows a communication system in an embodiment of the present invention, illustrating an example using terminal equipment and network equipment. As shown in Figure 1, the communication system 100 may include network equipment 101 and terminal equipment 102 and 103. For convenience, Figure 1 uses two terminal devices and one network device as examples, but embodiments of the present invention are not limited to these.

[0030] In embodiments of the present invention, existing or future operational tasks may be transmitted between the network device 101 and terminal devices 102 and 103. For example, these tasks include, but are not limited to, eMBB (enhanced Mobile Broadband), mMTC (massive Machine Type Communication), and URLLC (Ultra-Reliable and Low-Latency Communication).

[0031] Although Figure 1 shows that both terminal devices 102 and 103 are within the coverage of network device 101, the present invention is not limited to this. Both terminal devices 102 and 103 may be outside the coverage of network device 101, or one terminal device 102 may be within the coverage of network device 101 and the other terminal device 103 may be outside the coverage of network device 101.

[0032] In embodiments of the present invention, the upper-layer signaling may be, for example, radio resource control (RRC) signaling, referred to as an RRC message, and including, for example, MIB, system information, and dedicated RRC messages; or referred to as an RRC IE (RRC information element). The upper-layer signaling may further be, for example, MAC (Medium Access Control) signaling, or referred to as a MAC CE (MAC control element). However, the present invention is not limited to these.

[0033] In mobile communication systems, terminal devices typically measure channel state information (CSI) based on instructions and settings from network devices, and then report the measured CSI to the network devices. When scheduling for the terminal devices, the network devices refer to the CSI to schedule the terminal devices to transmit using appropriate resources and transmission methods. Different terminal devices may go through different physical channel conditions, and by employing a CSI feedback mechanism, resources can be utilized rationally and efficiently, thereby improving the overall efficiency of network transmission.

[0034] In the NR's CSI feedback mechanism, terminal equipment measures and reports a reference signal based on the CSI settings. The CSI may include CQI (Channel Quality Indicator), PMI (Precoding Matrix Indicator), Channel Measurement Reference Signal Resource Indicator (CSI-RS Resource Indicator, CRI), Synchronization signal / physical broadcast channel (SS / PBCH) block resource indicator (SS / PBCH Resource Indicator, SSBRI), layer indicator (LI), and rank indicator (RI).

[0035] In the NR's CSI reporting framework, CSI reports are associated with CSI resources. CSI reports may be configured in three types: periodic CSI reports (P-CSI), transmitted only on the Physical Uplink Control Channel (PUCCH); semi-persistent CSI reports (SP-CSI), transmitted on the PUCCH or Physical Uplink Shared Channel (PUSCH); and aperiodic CSI reports (AP-CSI), transmitted only on the PUSCH.

[0036] First, we will explain semi-persistent CSI based on PUSCH (or semi-persistent CSI delivered by PUSCH, hereinafter abbreviated as PUSCH semi-persistent CSI).

[0037] In the CSI feedback framework, network devices configure a set of trigger states for terminal devices using the RRC upper-layer parameter CSI-SemiPersistentOnPUSCH-TriggerStateList, and each trigger state corresponds to one CSI reporting setting. Network devices activate or deactivate a trigger state using the CSI request field (also called the CSI request area) in the DCI, and there may be multiple push-based SP-CSIs that are active at the same time. A terminal device (UE) does not expect to receive a DCI that is scrambled by SP-CSI-RNTI, and that DCI is activating a semi-permanent CSI report with the same CSI-reportconfigid that was activated by the previous DCI.

[0038] Based on the order of the trigger states set in CSI-SemiPersistentOnPUSCH-TriggerStateList, the codepoint in the CSI request field in DCI is mapped to the SP-CSI trigger state; for example, codepoint "0" is mapped to the trigger state at the first position. Regarding the activation or deactivation of a semi-persistent CSI, the terminal device can verify the DCI's PDCCH only when the following conditions are met, i.e., - The CRC parity check bits of the DCI format are scrambled using SP-CSI-RNTI, which is provided by the higher-layer parameter sp-CSI-RNTI; and - The settings for the special fields in the DCI format are as shown in Table 1 or Table 2 below.

[0039] Table 1 shows specific fields for PDCCH validation of semi-persistent CSI activation.

[0040] [Table 1] Table 2 shows the specific fields for PDCCH verification of semi-persistent CSI deactivation.

[0041] [Table 2] If verification is successful, the terminal device considers the information in the DCI format to be a valid activation or deactivation of semi-persistent CSI transmission based on PUSCH, and activates or deactivates the CSI reporting setting indicated by the CSI request field in the DCI. If verification fails, the terminal device considers that one mismatched CRC has been detected in the DCI format.

[0042] For example, the terminal device receives the trigger state list CSI-SemiPersistentOnPUSCH-TriggerStateList set by RRC. The terminal device receives DCI format 0_1 / 0_2. If the DCI format is scrambled by SP-CSI-RNTI and the special fields in DCI Format 0_1 ​​are activations corresponding to semi-persistent CSIs, the terminal device obtains the CSI report config ID based on the CSI trigger state corresponding to the codepoint in the CSI request field, and determines the CSI report that needs to be activated.

[0043] For example, a terminal device receives DCI format 0_1 / 0_2. If the DCI format is scrambled by SP-CSI-RNTI and the special fields in DCI Format 0_1 ​​are deactivations corresponding to semi-persistent CSIs, the terminal device obtains a CSI report config ID based on the CSI trigger state corresponding to the codepoint in the CSI request field, and determines which CSI report needs to be deactivated.

[0044] The CSI-SemiPersistentOnPUSCH-TriggerStateList IE is used to set a trigger state list for semi-persistent CSI reporting on terminal devices. For example, it may be as shown in Table 3 below.

[0045] Table 3 shows the CSI-SemiPersistentOnPUSCH-TriggerStateList IE.

[0046] [Table 3] The following describes non-periodic CSI based on PUSCH (or non-periodic CSI carried by PUSCH, hereinafter abbreviated as PUSCH non-periodic CSI).

[0047] In the CSI feedback framework, network devices configure a set of trigger states for terminal devices using the RRC upper-layer parameter CSI-AperiodicTriggerStateList, and each trigger state may correspond to multiple CSI reporting settings. Network devices activate one trigger state using the CSI request field in DCI.

[0048] The CSI-AperiodicTriggerStateList IE is used to configure an aperiodic trigger state list for terminal equipment. Each code point in the DCI field "CSI request" is associated with one trigger state. When a value associated with a trigger state is received, the terminal equipment measures CSI-RS, CSI-IM and / or SSB (reference signal) and performs an aperiodic report at L1 based on all entries in associatedReportConfigInfoList for that trigger state.

[0049] Table 4 shows the CSI-AperiodicTriggerStateList IE.

[0050] [Table 4] The following describes semi-persistent CSI based on PUCCH (or semi-persistent CSI delivered by PUCCH, hereinafter abbreviated as PUCCH semi-persistent CSI).

[0051] For PUCCH semi-persistent CSIs, the PUCCH resource for transmitting CSI reports is configured by reportConfigType. PUCCH semi-persistent CSIs are activated by an activation command, which selects one semi-persistent reporting configuration for PUCCH for use by the terminal device. The terminal device transmits a PUCCH with HARQ-ACK information in slot n, corresponding to the PDSCH carrying the activation command, in slot n+3N. slot subframe,μ Starting from the first slot after that, the specified semi-persistent reporting settings should be applied, where μ is the SCS setting for PUCCH.

[0052] Figure 2 shows a PUCCH SP-CSI reporting activation / deactivation MAC CE in an embodiment of the present invention, which is labeled by a MAC subheader with one LCID. As shown in Figure 2, the MAC CE has a fixed size of 16 digits (bits) and includes the following fields, namely: -Service Cell ID: This field represents the identifier (ID) of the service cell to which MAC CE applies, and the field length is 5 digits (bits); -BWP ID: This field represents the UL BWP to which MAC CE applies and is the code point of the DCI bandwidth portion indicator field. The field length of the BWP ID is two digits; -S i : Represents the activation / deactivation state of semi-persistent CSI reporting settings in CSI-reportconfigtoaddmodlist. S0 indicates a reporting setting and includes specifying the PUCCH resource for SP CSI reporting in BWP that has the lowest CSI-reportconfigid in the list where the type setting is semiPersistentOnPUCCH; S1 indicates a reporting setting and includes specifying the PUCCH resource for SP CSI reporting in BWP that has the second lowest CSI-reportconfigid; others can be inferred from this. MAC entities are S when the number of reporting settings in the list where the type setting is semiPersistentOnPUCCH in BWP is specified to be less than i+1. i Ignore the field. S i Setting the field to 1 indicates that the corresponding semi-persistent CSI reporting setting is activated. i Setting the field to 0 indicates that the corresponding semi-persistent CSI reporting setting is deactivated; and -R: This is a spare bit and is set to 0.

[0053] The above describes exemplary examples of semi-sustaining CSI based on PUSCH, non-periodic CSI based on PUCCH, and semi-sustaining CSI based on PUCCH, but the embodiments of the present invention are not limited to these.

[0054] The inventors have discovered the following: In order to achieve energy savings in the network, network equipment needs to adjust antenna settings, such as the number of antenna elements and antenna ports, to serve terminal equipment based on the real-time needs of network operations. To ensure that network equipment can acquire CSIs in real time and accurately, one viable scheme is for terminal equipment to simultaneously report multiple CSIs corresponding to different antenna setting schemes at the time of reporting. However, how network equipment can issue CSI instructions to terminal equipment to cause terminal equipment to report multiple CSIs remains an unresolved issue. The following explanation will use an energy-saving scenario as an example, but the present invention is not limited to this and can be applied to any scenario involving channel status information reporting.

[0055] <Example of the first side view> An embodiment of the present invention provides a method for indicating channel status information, which will be explained from the perspective of the terminal device. Figure 3 is a diagram showing the method for indicating channel status information in an embodiment of the present invention. As shown in Figure 3, the method includes the following, namely, 301: A terminal device receives a channel status information (CSI) reporting setting, the channel status information (CSI) reporting setting is associated with L CSIs, the channel status information (CSI) reporting setting includes S sub-settings, of which 1 ≤ S ≤ L, and one of the S sub-settings corresponds to at least one channel status information (CSI); and 302: The terminal device receives instruction information, and the instruction information is used to trigger / instruct / activate at least one of the S sub-settings.

[0056] Figure 3 above is provided to illustrate an embodiment of the present invention, but the present invention is not limited thereto. For example, the execution order between each operation can be appropriately adjusted, or several other operations can be appropriately added or removed. Those skilled in the art can make appropriate modifications based on the above description, without being limited to the description in Figure 3.

[0057] In some embodiments, the number of semi-persistent CSI reporting settings based on PUSCH, including at least one sub-setting, is H, and / or the number of aperiodic CSI reporting settings based on PUSCH, including at least one sub-setting, is Q, and / or the number of semi-persistent CSI reporting settings based on PUCCH, including at least one sub-setting, is R, where H, Q, and R are positive integers.

[0058] For example, the number H of semi-persistent CSI reporting settings based on PUSCH that include at least one sub-setting is 1, and / or the number Q of aperiodic CSI reporting settings based on PUSCH that include at least one sub-setting is 1, and / or the number R of semi-persistent CSI reporting settings based on PUCCH that include at least one sub-setting is 1.

[0059] In some embodiments, one CSI reporting setting includes P CSI sub-settings, each of which corresponds to one CSI, for example, one spatial domain / energy domain adjustment mode. A terminal device can report N CSIs at one CSI reporting time, and these N CSIs are associated with N CSI sub-settings out of the P sub-settings.

[0060] The terminal device reports a CSI report at the CSI reporting time, and the CSI report includes the first CSI, second CSI, ..., nth CSI, each corresponding to sub-setting 1, sub-setting 2, ..., sub-setting N of the CSI, and different sub-settings correspond to different spatial domain / energy domain adjustment modes.

[0061] Taking N=4 as an example, the CSI report includes four CSIs: the first CSI (CSI with sub-setting 1) corresponds to the spatial domain adjustment mode of the CSI-RS32 port, the second CSI (CSI with sub-setting 2) corresponds to the spatial domain adjustment mode of the 16 port, the third CSI (CSI with sub-setting 3) corresponds to the spatial domain adjustment mode of the 8 port, and the fourth CSI (CSI with sub-setting 4) corresponds to the spatial domain adjustment mode of the 4 port.

[0062] In some embodiments, the first CSI is a CSI baseline. For example, if the CSI-RS resource set includes multiple resources and each resource is associated with at least one spatial domain adjustment mode, each resource is associated with four spatial domain adjustment modes, the four spatial domain adjustment modes correspond to 32 ports, 16 ports, 8 ports, and 4 ports, respectively, and the 16 ports, 8 ports, and 4 ports are subsets of the 32 ports. In other words, the resources associated with the second, third, and fourth CSIs are subsets of the resources associated with the first CSI, and some information from the second, third, and fourth CSIs can be obtained from the first CSI, so the first CSI becomes a CSI baseline.

[0063] In the embodiments of the present invention, for the sake of explanation, the first CSI, second CSI, ..., nth CSI can be replaced with the CSIs of sub-setting 1, sub-setting 2, ..., sub-setting N. The sub-settings can be replaced with groups, configurations, modes, patterns, sub-groups, sub-modes, sub-patterns, and so on.

[0064] In some embodiments, the sub-configuration includes at least one piece of information, namely, parameter N1; parameter N2; parameter Ng; codebook subset restriction; and port information, the port information being used to indicate a portion of the Channel Status Information Reference Signal (CSI-RS) resources associated with the Channel Status Information (CSI) reporting configuration.

[0065] For example, port information is in the form of a bitmap that indicates a subset of ports, where each bit in the bitmap represents one port, one code division multiplexing (CDM) group, or a predefined group of ports.

[0066] In some embodiments, the maximum number of sub-configurations included in the CSI report configuration can be set by an RRC parameter, for example, maxNrOfSubConfig, which is included in Multiplicity and type constraint definitions or CSI-ReportConfig.

[0067] In some embodiments, the sub-configuration is included in the sub-configuration information (e.g., sub-config) of the channel status information (CSI) reporting configuration, or in the codebook configuration information (e.g., codebook config) of the channel status information (CSI) reporting configuration, or in the parameter configuration information (e.g., N1-N2 config) of the channel status information (CSI) reporting configuration.

[0068] For example, a CSI reporting configuration may include a sub-config list, where one sub-config in the list contains codebook configuration information (codebook config or codebook Type or codebook subset restrictions, N1, N2, and Ng) and / or port information, or a CSI reporting configuration may include P sub-configs, i.e., sub-config 1 to sub-config P, where each sub-config contains codebook configuration information (codebook config or codebook Type or codebook subset restrictions) and / or port information.

[0069] Furthermore, for example, the codebook config in the CSI reporting settings includes codebook config 1 to codebook config P, each corresponding to P sub-configurations. One of the codebook configs from codebook config 1 to codebook config P includes information such as codebook subset restrictions, N1, N2, and Ng. The port information indicated by the port subset does not need to be obtained through explicit instruction information, but can be obtained through other predefined or implicit methods.

[0070] Furthermore, for example, the codebook config in the CSI reporting configuration includes N1-N2 1 to N1-N2 P, each corresponding to P sub-configurations, and one of the codebook configurations from codebook configuration 1 to codebook configuration P contains information such as N1, N2, and Ng. The port information indicated by the port subset does not need to be obtained by explicit instruction information, but can be obtained by other predefined or implicit methods. In the CSI reporting configuration, only one common codebook subset restriction parameter is set, and the codebook subset restriction information for each sub-configuration can be obtained from the shared codebook subset restriction parameter based on the N1, N2, and Ng parameters.

[0071] A CSI report configuration includes P sub-configurations, a CSI report may include P-1 sub-configurations / codebook configuration indexes / indicators / information, a sub-configuration list may include P-1 sub-configurations, or a codebook configuration list may include P-1 codebook configurations. Each of the aforementioned P-1 sub-configurations / codebook configuration indexes / indicators / information, or P-1 sub-configurations, or P-1 codebook configurations corresponds to P-1 sub-configurations, and the resource configuration and codebook configuration included in the CSI report configuration are one sub-configuration, thus resulting in a CSI report configuration containing P sub-configurations.

[0072] Alternatively, the CSI report setting may include P sub-settings, the CSI report may include P sub-setting / codebook setting indexes / indicators / information, or the sub-setting list may include P sub-settings, or the codebook setting list may include P codebook settings, and one of the P sub-setting / codebook setting indexes / indicators / information or the P sub-settings or the P codebook settings is a resource setting and a codebook setting included in the CSI report setting, thereby the CSI report setting includes P sub-settings.

[0073] In the embodiments of the present invention, the terms “index,” “label,” and “information” are interchangeable, and the present invention is not limited thereto.

[0074] In some embodiments, the channel status information (CSI) reporting setting may be set by radio resource control (RRC) signaling, and the instruction information may be DCI or MAC CE. The instruction information is used to instruct a terminal device to report a CSI report at the CSI reporting time, and the CSI report includes N CSIs, i.e., the first CSI, the second CSI, ..., the nth CSI, in other words, the CSI of sub-setting 1, the CSI of sub-setting 2, ..., the CSI of sub-setting N.

[0075] Figure 4 is another diagram showing a method for indicating channel state information in an embodiment of the present invention. As shown in Figure 4, the method includes the following: 401: A terminal device receives a channel status information (CSI) reporting setting, the channel status information (CSI) reporting setting is associated with L CSIs, the channel status information (CSI) reporting setting includes S sub-settings, of which 1 ≤ S ≤ L, and one of the S sub-settings corresponds to at least one channel status information (CSI); and 402: The terminal device receives instruction information, and the instruction information is used to trigger (instruct / activate) at least one of the S sub-settings.

[0076] As shown in Figure 4, the method further includes the following: CD, 403: The terminal device performs channel measurements based on M sub-settings out of S sub-settings that have been triggered / instructed / activated; and 404: The terminal device transmits a channel status information (CSI) report, and the channel status information (CSI) report contains N channel status information (CSIs), of which the M sub-settings correspond to N channel status information (CSIs), and 1 ≤ M ≤ N.

[0077] Figure 4 above is provided to illustrate an embodiment of the present invention, but the present invention is not limited thereto. For example, the execution order between each operation can be appropriately adjusted, or several other operations can be appropriately added or removed. Those skilled in the art can make appropriate modifications based on the above description, without being limited to the description in Figure 4.

[0078] In some embodiments, the channel status information (CSI) reporting setting is for physical uplink shared channel (PUSCH) semi-persistent CSI reporting (PUSCH semi-persistent CSI reporting). The RRC can configure a first trigger / indication / activation state list, which contains a set of X1 trigger (indication / activation) states.

[0079] In some embodiments, the first trigger / indication / activation state list of PUSCH semi-persistent CSI reporting is S sub-configurations in the CSI reporting configuration, and one trigger / indication / activation state in the list is one sub-configuration. Alternatively, one trigger (indication / activation) state in the list is associated with one CSI reporting configuration, that is, one trigger (indication / activation) state in the list is associated with and includes one related reporting configuration information, and the related reporting configuration information may be associated with at least one sub-configuration, that is, the related reporting configuration information includes one related sub-configuration list.

[0080] For example, sub-config 1 to sub-config S or codebook config 1 to codebook config S in the CSI reporting configuration are S sub-configurations, and each trigger / indication / activation is one sub-configuration. When one sub-configuration corresponds to one CSI, X = S = L; when one sub-configuration corresponds to multiple CSIs, X = S < L. Thereby, the overhead of RRC signaling can be reduced, and there is no need to set the trigger / indication / activation (state) list separately.

[0081] In some embodiments, the first trigger / indication / activation state list of PUSCH semi-persistent CSI reporting is an existing IE or a newly defined IE, and one trigger (indication / activation) state in the list is associated with at least one CSI reporting configuration index and / or at least one sub-configuration. Alternatively, one trigger (indication / activation) state in the list is associated with one CSI reporting configuration, that is, one trigger (indication / activation) state in the list is associated with and includes one related reporting configuration information, and the related reporting configuration information may be associated with at least one sub-configuration, that is, the related reporting configuration information includes one related sub-configuration list.

[0082] For example, the first trigger / indication / activation state list for a PUSCH semi-persistent CSI report may reuse an existing IE (e.g., CSI-SemiPersistentOnPUSCH-TriggerStateList), with a new parameter added to each trigger state in the list, the parameter being used to associate with a sub-configuration or CSI-RS resource, such as associatedsub ConfigInfo or associatedResourceConfigInfo. The parameter type or value may be a sub-configuration index or a CSI-ResourceConfig index, the sub-configuration index being an index of one of S sub-configurations in the CSI reporting configuration, and the sub-configuration index may be a positive integer.

[0083] The newly added parameter (associatedSubConfigInfo or associatedResourceConfigInfo) is optional. For example, when the trigger state is used only for activating / deactivating CSI reporting, the newly added parameter (associatedSubConfigInfo or associatedResourceConfigInfo) is not set, and / or when the trigger state is used for activating / deactivating CSI reporting and triggering / indicating / activating sub-configurations, the newly added parameter (associatedSubConfigInfo or associatedResourceConfigInfo) is set, and the trigger state is associated with CSI-ReportConfigId and also with sub-configurations or CSI-ResourceConfig. Thus, the primary trigger / indication / activation state list for PUSCH semi-persistent CSI reporting is used for activating / deactivating CSI reporting as well as for triggering / indicating / activating sub-configurations.

[0084] Table 5 shows one example of a trigger / indication / activation state list for PUSCH semi-persistent CSI reporting.

[0085] [Table 5] Table 6 shows another example of a trigger / indication / activation status list for PUSCH semi-persistent CSI reporting.

[0086] [Table 6] Furthermore, for example, the primary trigger / indicator / activation state list for PUSCH semi-persistent CSI reporting may be a newly defined list, for example, named CSI-SemiPersistentOnPUSCH-TriggerStateList-r18, or CSI-SemiPersistentOnPUSCH-subConfig-TriggerStateList, or NES-sub-CSI-SemiPersistent OnPUSCH-TriggerStateList, and one trigger / indicator / activation state in the list may be associated with one CSI reporting configuration and / or at least one CSI-RS resource configuration index and / or at least one sub-configuration, and the primary trigger / indicator / activation state list can be used to activate / deactivate CSI reporting as well as to trigger / indicate / activate sub-configurations.

[0087] Table 7 shows another example of a trigger / indication / activation status list for PUSCH semi-persistent CSI reporting.

[0088] [Table 7] In the above examples of IE reuse and new IE definitions, some trigger / indicator / activation states in the primary trigger state list of a PUSCH semi-persistent CSI report are associated with the CSI reporting settings index and used for activating / deactivating the CSI report, while other trigger / indicator / activation states in the list are associated with the CSI reporting settings index and / or sub-settings and can be used simultaneously for activating and deactivating the CSI reporting settings associated with the trigger / indicator / activation states, and for triggering / indicating / activating sub-settings in the CSI reporting settings, or may be used only for triggering / indicating / activating sub-settings. This allows for saving RRC overhead by sharing the primary trigger / indicator / activation state list for CSI activation / deactivation and sub-setting triggering / indicating / activating.

[0089] Furthermore, for example, the primary trigger / indicator / activation state list for PUSCH semi-persistent CSI reporting is a newly defined IE, where one trigger / indicator / activation state in the list is associated with one CSI reporting setting index and at least one sub-setting, and is used for triggering / indicating / activating the sub-setting in the CSI reporting setting. Thus, CSI-SemiPersistentOn PUSCH-TriggerStateList is used for activating / deactivating CSI reporting, and the primary trigger / indicator / activation state list is used for triggering / indicating / activating the sub-setting.

[0090] Furthermore, for example, the primary trigger / indication / activation state list for PUSCH semi-persistent CSI reporting is a newly defined IE, where one trigger / indication / activation state in the list is associated with at least one sub-configuration and is used for triggering / indicating / activating the at least one sub-configuration. In this method, there is no need to indicate the CSI reporting configuration index, as there is only one CSI reporting configuration, network devices and terminal devices tacitly know the CSI reporting index, or the CSI reporting configuration index is indicated by other RRC lists and DCI areas, so there is no need to indicate the CSI reporting configuration index here. Thus, the CSI-SemiPersistentOnPUSCH-TriggerStateList can be used for activating / deactivating CSI reporting, and the primary trigger / indication / activation state list can be used for triggering / indicating / activating sub-configurations.

[0091] In the embodiments described above, one trigger / indication / activation state in the first trigger / indication / activation state list may be associated with one CSI reporting setting index and / or at least one sub-setting, the sub-setting may be a sub-setting (index) in the CSI reporting setting, a codebook setting (index), port subset instruction information (index), n1-n2 setting (index), a CSI-RS resource index, etc., and each sub-setting related parameter is associated with one spatial domain / energy domain adjustment element mode.

[0092] For example, one trigger / indicator / activation state in the first trigger / indicator / activation state list is associated with one CSI reporting setting index and at least one sub-setting, and when the trigger / indicator / activation state is activated, it indicates that the at least one sub-setting in the CSI reporting setting is triggered / indicated / activated, or that the CSI reporting setting index is activated and the at least one sub-setting in the CSI reporting setting is triggered / indicated / activated.

[0093] Furthermore, for example, if one trigger / instruction / activation state in the first trigger / instruction / activation state list is associated with at least one sub-configuration piece of information, it indicates that the at least one sub-configuration is triggered / instructed / activated.

[0094] Furthermore, for example, one trigger / indication / activation state in the first trigger / indication / activation state list is associated with at least one CSI-RS resource index. For example, one CSI-RS resource set contains multiple resources, each resource corresponding to one sub-configuration, i.e., one spatial domain / energy domain element tuning mode, and one trigger / indication / activation state is associated with at least one CSI-RS resource index. When the trigger / indication / activation state is activated, it indicates that the corresponding at least one sub-configuration is triggered / indicated / activated.

[0095] The above provides an illustrative explanation of CSI reporting settings; the following provides an illustrative explanation of instruction information.

[0096] In some embodiments, the instruction information is downlink control information (DCI). The downlink control information (DCI) is user-specific, and the downlink control information is scrambled by a first RNTI. The first RNTI may be an RNTI related to network energy saving, different from SP-CSI-RNTI or C-RNTI, or the first RNTI may be SP-CSI-RNTI or C-RNTI.

[0097] For example, dedicated RNTIs for network energy saving, such as NES-RNTI and NES-SP-CSI-RNTI, may be newly defined. Details on how these RNTIs are generated can be found in the related technologies, and these newly defined RNTIs may also be used for other functions. Furthermore, for example, the first RNTI may be an existing SP-CSI-RNTI or C-RNTI.

[0098] In some embodiments, the downlink control information (DCI) is in DCI format 0_1 ​​or DCI format 0_2, and the CSI request field and / or first trigger / indication / activation field (which may be abbreviated as the first indication field, e.g., a sub-CSI indication field) in the downlink control information (DCI) are used to activate one CSI report and / or indicate at least one of the multiple sub-settings.

[0099] For example, the DCI format can reuse the existing DCI format (0_1, 0_2), the DCI area may reuse the existing CSI request area, or other idle areas in the DCI format, and the DCI's first trigger / indicator / activation field may be the CSI request area or another existing area. The maximum bit width of the CSI request area is fixed at 6, and the bit width of the DCI area determines the number of active states in the first trigger / indicator / activation state list. Alternatively, the first trigger / indicator / activation field may be a part of the CSI request area, and this first trigger / indicator / activation field may be used simultaneously for CSI activation / deactivation and sub-setting trigger / indicator / activation.

[0100] The first trigger / indicator / activation state list set by RRC is an existing IE (e.g., CSI-Semi PersistentOnPUSCH-TriggerStateList) or a newly defined IE (e.g., CSI-Semi PersistentOnPUSCH-TriggerStateList-r18), where one of the trigger / indicator / activation states in the list is associated with one CSI reporting setting, and one of the trigger / indicator / activation states is associated with one CSI reporting setting and / or at least one sub-setting.

[0101] If the CSI request area is associated with a CSI reporting setting index that has only one trigger state indicated, the activation / deactivation of the CSI report is performed, but the trigger / indication / activation of the sub-settings is not performed.

[0102] When the trigger state indicated by the CSI request area is associated with the CSI reporting setting and sub-settings, if the CSI reporting is not activated, the CSI reporting is activated, and the trigger / indication / activation of the sub-settings in the CSI reporting setting is performed, and if the CSI reporting setting is not activated, the adjustment / update / re-indication of the sub-settings of the CSI reporting setting is performed, and the updated sub-settings overwrite the previously indicated sub-settings.

[0103] When the trigger state indicated by the CSI request area is associated only with sub-configurations, it indicates that there is only one CSI reporting configuration that configures multiple sub-configurations. Based on the RRC's CSI reporting configuration information, terminal and network devices know the CSI reporting configuration index which includes multiple sub-configurations, and therefore terminal devices can trigger / indicate / activate the sub-configurations.

[0104] Furthermore, for example, the first trigger / indication / activation field of DCI is a newly defined domain, e.g., CSI-request-r18, and this newly defined domain is used simultaneously for activating / deactivating the CSI report and triggering / indicating / activating the sub-configuration. The bit width of the domain may be larger in order to be used simultaneously for activating / deactivating the CSI and triggering / indicating / activating the sub-configuration, thereby making the triggering / indication / activation of the sub-configuration more flexible and unrestricted.

[0105] The first trigger / indicator / activation state list set by RRC is either an existing IE (e.g., CSI-Semi PersistentOnPUSCH-TriggerStateList) or a newly defined IE (e.g., CSI-Semi PersistentOnPUSCH-TriggerStateList-r18), where one of the trigger / indicator / activation states in the list is associated with one CSI reporting setting, and one of the trigger / indicator / activation states is associated with one CSI reporting setting and at least one sub-setting.

[0106] If the trigger state indicated by CSI request-r18 is associated only with the CSI reporting settings index, the activation / deactivation of the CSI report will be performed, but the trigger / indication / activation of the sub-settings will not be performed.

[0107] If the trigger state indicated by CSI request-r18 is associated with a CSI reporting setting and sub-settings, and the CSI reporting is not activated, the CSI reporting is activated, and the sub-settings in the CSI reporting setting are triggered / indicated / activated. If the CSI reporting setting is activated, the sub-settings of the CSI reporting setting are adjusted / updated / re-indicated, and the updated sub-settings overwrite the previously indicated sub-settings.

[0108] When the trigger state indicated by CSI request-r18 is associated only with sub-configurations, it indicates that there is only one CSI reporting configuration that configures multiple sub-configurations. Based on the RRC's CSI reporting configuration information, terminal devices and network devices know the CSI reporting configuration index that contains multiple sub-configurations, and therefore the terminal devices perform the trigger / instruction / activation of the sub-configurations in the CSI reporting configuration.

[0109] In the example above, one list set by RRC + one domain in DCI is used for activating / deactivating CSI and triggering / indicating / activating sub-configurations.

[0110] Furthermore, for example, the DCI's primary trigger / indication / activation field is a newly defined domain. The existing CSI request domain and the newly defined domain jointly trigger / indicate / activate N1 sub-settings out of S sub-settings in the CSI reporting configuration. Of these, the CSI request domain is used for activating / deactivating CSI reporting, while the newly defined domain is used to trigger / indicate / activate sub-settings in the CSI reporting configuration index where the CSI request has been activated.

[0111] For example, in the case of a CSI request area + a newly defined DCI area, the newly defined DCI area will be all zeros or invalid values, and will perform activation / deactivation of the CSI, but will not perform trigger / instruction / activation of the sub-settings.

[0112] Furthermore, for example, in the case of a CSI request area + a newly defined DCI area, if the newly defined DCI area is a non-zero or valid value and the CSI report is not activated, the system will activate / deactivate the CSI report and trigger / instruct / activate the sub-settings. If the CSI report is activated, the system will adjust / update / re-instruct the sub-settings of the CSI report settings, and the updated sub-settings will override the previously instructed sub-settings.

[0113] In the example above, RRC may configure two lists: one the original CSI-SemiPersistent OnPUSCH-TriggerStateList and the other the newly defined list. The two domains in DCI are the original CSI request and the newly defined DCI domain. The CSI request domain is used for activating / deactivating the CSI, and the newly defined DCI domain is used for triggering / indicating / activating sub-configurations.

[0114] In some embodiments, for semi-persistent CSI reporting based on PUSCH, a CSI request field and / or a first trigger / indication / activation field (e.g., sub-CSI indication field) in the downlink control information (DCI) are used to activate / deactivate at least one CSI report and / or indicate at least one of the multiple sub-settings, based on a special field in the DCI.

[0115] In some embodiments, the special field in the downlink control information (DCI) is one or more existing domains in the DCI (e.g., HARQ process number and / or Redundancy Version), and includes a semi-persistent CSI activation / deactivation PDCCH verification domain.

[0116] In some embodiments, the special field in the downlink control information (DCI) is a region related to network energy saving, distinct from the semi-persistent CSI activation / deactivation PDCCH verification region.

[0117] For example, the first specific field of a valid trigger / indication / activation PDCCH verification is used to verify the trigger / indication / activation of a PUSCH semi-persistent CSI subconfiguration. If the verification is successful, the terminal device (UE) considers the information in the DCI format to be a valid trigger / indication / activation of the PUSCH semi-persistent CSI subconfiguration. If the verification fails, the UE considers that one mismatched CRC has been detected in the DCI format.

[0118] The first specific field may be the domain for semi-persistent CSI activation PDCCH verification (e.g., HARQ process number and / or Redundancy version), and the existing CSI activation specific field may be used as is, as shown in Table 1. The first specific field may also be a newly defined domain and is used to verify the trigger / indication / activation of the PUSCH semi-persistent CSI sub-configuration.

[0119] Furthermore, for example, the first specific field of the valid release / deactivation PDDCH verification is used to verify the release / deactivation of the PUSCH semi-persistent CSI sub-configuration trigger / instruction / activation command. If the verification is successful, the terminal device (UE) considers the information in the DCI format to be a valid release / deactivation of the valid trigger / instruction / activation command for the PUSCH semi-persistent CSI sub-configuration. If the verification fails, the UE considers that one mismatched CRC has been detected in the DCI format.

[0120] The first specific field may be the domain for semi-persistent CSI deactivation PDCCH verification (e.g., HARQ process number and / or Modulation and coding scheme and / or Resource block assignment and / or Redundancy version), and the existing CSI deactivation specific field may be used as is, as shown in Table 2. The first specific field may also be a newly defined domain and is used to verify the release / deactivation of the trigger / instruction / activation command for the PUSCH semi-persistent CSI sub-configuration.

[0121] All valid triggers / indicators / activators and valid releases of the sub-configurations for the PUSCH semi-persistent CSI may have specific fields, and the valid trigger / indicator / activator specific field and the valid release / deactivation specific field may have the same setting value or different setting values.

[0122] Alternatively, a valid trigger / instruction / activation of a sub-configuration of a PUSCH semi-persistent CSI has a specific field, while a valid release / deactivation does not have a specific field; that is, it is not necessary to set a specific field for a valid release / deactivation. For example, deactivating a CSI represents a valid release / deactivation of a sub-configuration that is being triggered / instructed / activated.

[0123] Alternatively, all valid triggers / indicators / activations and valid releases of sub-configurations for PUSCH semi-persistent CSIs do not have specific fields, i.e., none of them require setting specific fields. At least in the following cases, no valid triggers / indicators / activations and valid releases require specific fields, i.e., In a single DCI, it is possible to activate a semi-persistent CSI reporting setting index and simultaneously trigger / instruct / activate S sub-settings within the activated CSI reporting setting. In such cases, the DCI is scrambled using SP-CSI-RNTI, and specific fields in the DCI are specific fields for semi-persistent CSI activation PDCCH verification in existing standards (protocols). When a CSI is deactivated, specific fields in the DCI are specific fields for semi-persistent CSI deactivation PDCCH verification in existing protocols, representing the effective release / deactivation of the sub-settings.

[0124] In some embodiments, the size / number of bits of the first trigger / indication / activation field (e.g., sub-CSI indication field) in the downlink control information (DCI) is predefined or set by RRC signaling.

[0125] For example, when the first trigger / indicator / activation field of a DCI is a newly defined DCI area, the first trigger / indicator / activation size is used to determine the bit width of the first trigger / indicator / activation field of the DCI, and the method for determining the first trigger / indicator / activation size may be as follows.

[0126] For example, determined by a predefined scheme, the first trigger / indicator / activation size is X, where X is a positive integer greater than 0, for example, the first trigger / indicator / activation size is 8, meaning the DCI's first trigger / indicator / activation field is 8 bits.

[0127] Furthermore, for example, the first trigger / indicator / activation size is set by RRC and / or the maximum value of the first trigger / indicator / activation size is set by RRC, for example, the first trigger / indicator / activation size is determined by the higher-level parameter nes-ReportTriggerSize, and the maximum value of the first trigger / indicator / activation size is determined by the higher-level parameter max-nes-ReportTriggerSize.

[0128] Furthermore, for example, the first trigger / indicator / activation size is set by RRC and / or the maximum value of the first trigger / indicator / activation size is set by a predefined method. For example, the maximum value of the first trigger / indicator / activation size is predefined to be 6, and the first trigger / indicator / activation size is determined by the higher-level parameter nes-ReportTriggerSize, which may be set to a positive integer between 0 and 6.

[0129] In some embodiments, the number of bits in the first trigger / instruction / activation field is log2X, where X is the number of trigger (instruction / activation) states. Of these, the number of bits corresponds to the trigger (instruction / activation) states in the order of their positions.

[0130] For example, the codepoints of the first trigger / instruction / activation field in the downlink control information are mapped to trigger (instruction / activation) states according to the order of the trigger state positions, and of these, codepoint "0" or codepoint "1" is mapped to the trigger / instruction / activation state at the first position.

[0131] For example, the first trigger / indicator / activation state list has a total of X rows, with each row corresponding to one trigger / indicator / activation state. The bit width of the first trigger / indicator / activation field in the DCI is log2X. Based on the order of the positions of the trigger states set in the trigger / indicator / activation state list, the codepoint of the first trigger / indicator / activation field in the DCI is mapped to the trigger / indicator / activation state in the list; for example, codepoint "0" or codepoint "1" is mapped to the trigger / indicator / activation state at the first position.

[0132] In some embodiments, the first trigger / indication / activation field (sub-CSI indication field) in the downlink control information (DCI) is a bitmap. The number of bits in the first trigger / indication / activation field is X, where X is the number of trigger / indication / activation states or the number of sub-settings in the CSI reporting settings, and the position of the bits corresponds in order to the trigger / indication / activation states or sub-settings. The MSB to LSB of the bitmap correspond to the first to last trigger / indication / activation states in the first trigger / indication / activation state list or to the first to last sub-settings in the CSI reporting settings, where 1 represents the trigger / indication / activation of the sub-setting and 0 represents the release / deactivation / deactivation of the sub-setting.

[0133] The DCI area and mapping have been explained illustratively above; further explanations will be provided below through examples.

[0134] In some embodiments, for example, the first trigger / indicator / activation state list set by RRC is an existing IE (e.g., CSI-Semi PersistentOnPUSCH-TriggerStateList) or a newly defined IE (e.g., CSI-Semi PersistentOnPUSCH-TriggerStateList-r18), one trigger / indicator / activation state in the list is associated with one CSI reporting setting and / or at least one sub-setting, in other words, some trigger / indicator / activation states in the list are associated with a CSI reporting setting index, and other trigger / indicator / activation states are associated with a CSI reporting setting index and / or at least one sub-setting, the DCI format reuses an existing DCI format (0_1,0_2), the first trigger / indicator / activation field of the DCI is a CSI request field or a newly defined field (e.g., CSI request field-r18), reusing an existing DCI field, and codepoint "0" or "1" maps to the first trigger / indicator / activation state.

[0135] In the case of SP-CSI activation, for example, the terminal device receives DCI 0_1 / 0_2. The terminal device activates the aforementioned CSI reporting setting if the DCI format is scrambled by SP-CSI-RNTI, the special fields in DCI Format 0_1 / 0_2 correspond to semi-persistent CSI activation PDCCH verification specific fields, the CSI request field or a newly defined field (e.g., CSI request field-r18) activates one trigger / indication / activation state, and the trigger / indication / activation state is associated with one CSI reporting setting index.

[0136] In the case of SP-CSI deactivation, for example, the terminal device receives DCI 0_1 / 0_2. The terminal device deactivates the aforementioned CSI reporting setting if the DCI format is scrambled by SP-CSI-RNTI, the special fields in DCI Format 0_1 / 0_2 correspond to semi-persistent CSI deactivation PDCCH verification specific fields, the CSI request field or a newly defined field (e.g., CSI request field-r18) corresponds to one trigger / indication / activation state, and the trigger / indication / activation state is associated with one CSI reporting setting index.

[0137] In the case of CSI activation + sub-configuration trigger / instruct / activation, for example, the terminal device receives DCI 0_1 / 0_2. If the DCI format is scrambled by SP-CSI-RNTI, the special fields in CI Format 0_1 ​​correspond to the semi-persistent CSI activation PDCCH verification specific field, the CSI request field or a newly defined field (e.g., CSI request field-r18) corresponds to one trigger / instruct / activation state, and the trigger / instruct / activation state is associated with one CSI reporting configuration index and at least one sub-configuration, the terminal device activates the CSI reporting configuration and triggers / instructs / activates the at least one sub-configuration in that CSI reporting configuration. CSI deactivation or the next trigger / instruct / activation of a sub-configuration represents a valid release / deactivation of the trigger / instruct / activation information for the current sub-configuration.

[0138] In the case of triggering / instructing / activating a sub-configuration after CSI activation, for example, the terminal device receives DCI format 0_1. If the DCI format is scrambled by SP-CSI-RNTI, the special fields in DCI Format 0_1 ​​are semi-persistent CSI activation PDCCH verification specific fields, the CSI request area corresponds to one trigger / instruction / activation state, and the trigger / instruction / activation state is associated with one CSI reporting configuration index and at least one sub-configuration, and the CSI reporting configuration was activated at a previous time using DCI scrambled by SP-CSI-RNTI, and the sub-configuration is triggered / instructed / activated at the same time as the CSI activation, the terminal device triggers / instructs / activates the sub-configuration in the CSI reporting configuration at the current time, and the trigger / instruction / activation information for the current sub-configuration overwrites the previous sub-configuration trigger / instruction / activation information. Deactivating CSI or triggering / instructing / activating the next sub-configuration indicates a valid release / deactivation of the current sub-configuration's trigger / instruction / activation information.

[0139] For example, at time T1, if the terminal device receives DCI format 0_1 ​​scrambled by SP-CSI-RNTI, the special field is the CSI semi-persistent CSI activation PDCCH verification specific field, and the trigger / instruction / activation state corresponding to the CSI request area is associated with {CSI report config1, 32 port CSI-RS subconfiguration, 16 port CSI-RS subconfiguration}, then the terminal device activates CSI report config1 and instructs 32 port CSI-RS and 16 port subconfigurations.

[0140] At time T2, the terminal device receives DCI format 0_1 ​​scrambled by SP-CSI-RNTI, the special field is the CSI semi-persistent CSI activation PDCCH verification specific field, the trigger / instruction / activation state corresponding to the CSI request area is associated with {CSI report config1, 8-port CSI-RS sub-configuration, 4-port CSI-RS sub-configuration}, and if the terminal device confirms that CSI report config1 has been activated, the terminal device re-instructs the sub-configurations of CSI report config1, updating / adjusting the 32-port CSI-RS and 16-port sub-configurations to the 8-port CSI-RS and 4-port CSI-RS sub-configurations.

[0141] In the case of re-triggering / instructing / activating sub-configurations after CSI activation, for example, the terminal device receives DCI format 0_1. When the DCI format is scrambled by SP-CSI-RNTI, and the special fields in DCI Format 0_1 ​​are trigger / instruction / activation fields for sub-configurations that are different from the semi-persistent CSI activation / deactivation PDCCH verification specific fields, and the CSI request area or a newly defined area (e.g., CSI request field-r18) corresponds to one trigger / instruction / activation state, and the trigger / instruction / activation state is associated with one CSI reporting setting index and at least one sub-configuration, and the CSI reporting setting was activated at some previous time using DCI scrambled by SP-CSI-RNTI, and trigger / instruction / activation is performed on the sub-configuration simultaneously with the activation of the CSI, the terminal device will trigger / instruction / activate the sub-configuration in the CSI reporting setting at the current time, and the trigger / instruction / activation information for the current sub-configuration will overwrite the previous sub-configuration trigger / instruction / activation information. Deactivating CSI or triggering / instructing / activating the next sub-configuration indicates a valid release / deactivation of the current sub-configuration's trigger / instruction / activation information.

[0142] In the case of triggering / instructing / activating a sub-configuration after CSI activation, for example, the terminal device receives DCI format 0_1. If the DCI format is scrambled by a newly defined RNTI for network energy saving, for example NES-RNTI, and the CSI request field or a newly defined field (for example CSI request field-r18) corresponds to one trigger / instruction / activation state, and the trigger / instruction / activation state is associated with one CSI reporting setting index and at least one sub-configuration, and the CSI reporting setting was activated at a previous time using DCI scrambled by SP-CSI-RNTI, and the trigger / instruction / activation is performed simultaneously with the CSI reporting activation for a sub-configuration, the terminal device will trigger / instruct / activate the sub-configuration in the CSI reporting setting at the current time, and at this time the trigger / instruction / activation information for the current sub-configuration will overwrite the trigger / instruction / activation information for the previous sub-configuration. Deactivating CSI or triggering / instructing / activating the next sub-configuration indicates a valid release / deactivation of the current sub-configuration's trigger / instruction / activation information.

[0143] As a result, the activation / deactivation of CSIs and the triggering / indicating / activating of sub-configurations share a single RRC configuration list and DCI area. This allows for the indication of multiple sub-configurations and multiple CSIs within the DCI area's triggering / indicating / activation mechanism, providing greater flexibility in instruction and saving DCI and RRC overhead.

[0144] In some embodiments, for example, RRC sets a primary trigger / indicator / activation state list, the list being a newly defined IE, e.g., CSI-SemiPersistentOnPUSCH-subConfig-TriggerStateList or NES-sub-CSI-Semi PersistentOnPUSCH-TriggerStateList, where one trigger / indicator / activation state in the list is associated with one CSI reporting configuration index and / or at least one subconfiguration, and RRC sets CSI-SemiPersistentOnPUSCH-TriggerStateList, DCI Format reuses the existing DCI format (0_1,0_2), the primary trigger / indicator / activation field of the DCI is a newly defined DCI area, the existing CSI-Semi PersistentOnPUSCH-TriggerStateList and CSI request field are used for activating / deactivating CSI reporting, and the primary trigger / indicator / activation state list and primary trigger / indicator / activation field are used for triggering / indicating / activating subconfigurations.

[0145] In either case, the first trigger / indicator / activation field may be a codepoint with a bit width of log2X, where X is the number of trigger / indicator / activation states or the number of rows in the first trigger / indicator / activation state list, and codepoint "0" or "1" is mapped to the trigger / indicator / activation state at the first position, and is mapped according to the order in which the trigger / indicator / activation state index in the first trigger / indicator / activation state list is arranged in ascending order, or the first trigger / indicator / activation field (NES sub-CSI indication field) may be a bitmap with a bit width of X, where X is the number of trigger / indicator / activation states or the number of rows in the first trigger / indicator / activation state list, and is arranged according to the ascending order in which the trigger / indicator / activation state index in the first trigger / indicator / activation state list, and the MSB or LSB of the bitmap corresponds to the first to last trigger / indicator / activation state.

[0146] In the case of SP-CSI activation, for example, the terminal device receives DCI 0_1. If the DCI format is scrambled by SP-CSI-RNTI, the special fields in DCI Format 0_1 ​​correspond to the activation of a semi-persistent CSI, and the newly defined first trigger / indication / activation field (NES sub-CSI indication field) is all zeros, an invalid value, or another reference value, the terminal device performs the CSI activation operation and determines the CSI report that needs to be activated based on the CSI request field.

[0147] In the case of SP-CSI deactivation, for example, the terminal device receives DCI 0_1. If the DCI format is scrambled by SP-CSI-RNTI, the special fields in DCI Format 0_1 ​​correspond to the deactivation of semi-persistent CSI, and the newly defined DCI field (NES sub-CSI indication field) is all zeros, invalid values, or other reference values, the terminal device performs the CSI deactivation operation and determines the CSI report that needs to be deactivated based on the CSI request field.

[0148] In the case of SP-CSI activation + sub-configuration trigger / indication / activation, for example, the terminal device receives DCI 0_1. If the DCI format is scrambled by SP-CSI-RNTI, the special fields in DCI Format 0_1 ​​correspond to the activation of semi-persistent CSI, and the newly defined first trigger / indication / activation field (NES sub-CSI indication field) is a non-zero valid value, the terminal device activates semi-persistent CSI reporting based on the CSI reporting configuration index corresponding to the CSI request area, and also triggers / indicates / activates sub-configurations based on the newly defined first trigger / indication / activation field (NES sub-CSI indication field), that is, it triggers / indicates / activates sub-configurations in the CSI reporting configuration activated by the CSI request area.

[0149] In the case of triggering / instructing / activating a sub-configuration after SP-CSI activation, for example, the terminal device receives DCI 0_1. If the DCI format is scrambled by SP-CSI-RNTI, the special fields in DCI Format 0_1 ​​correspond to the activation of a semi-persistent CSI, and the newly defined first trigger / instruction / activation field (NES sub-CSI indication field) is a non-zero valid value, the terminal device obtains the CSI reporting configuration index based on the CSI request area and performs triggering / instructing / activating the sub-configuration based on the newly defined first trigger / instruction / activation field (NES sub-CSI indication field). If the CSI reporting configuration was activated at a previous time using DCI scrambled by SP-CSI-RNTI, and triggering / instructing / activating a sub-configuration is performed simultaneously with the CSI reporting activation, the triggering / instructing / activating information for the current sub-configuration overwrites the previous sub-configuration triggering / instruction / activation information. Deactivating CSI or triggering / instructing / activating the next sub-configuration indicates a valid release / deactivation of the current sub-configuration's trigger / instruction / activation information.

[0150] For example, at time T1, the terminal device receives DCI 0_1 signaling scrambled by SP-CSI-RNTI, the CSI request area corresponds to CSI report config 1, the newly defined first trigger / indication / activation field (NES sub-CSI indication field) indicates the 32 / 16 port subconfiguration out of the four types of subconfigurations (32 / 16 / 8 / 4 port), and the specific field is the CSI activation PDCCH verification specific field. In this case, the terminal device activates CSI report config 1 based on the above signaling and triggers / indicates / activates two of the four types of subconfigurations (32 port and 16 port subconfigurations).

[0151] At time T2, CSI report config 1 is still in the activation period, the terminal device receives DCI 0_1 signaling scrambled by SP-CSI-RNTI, the CSI request area corresponds to CSI report config 1, the newly defined first trigger / indication / activation field (NES sub-CSI indication field) indicates the 8-port subconfiguration out of the four types of subconfigurations (32 / 16 / 8 / 4 ports), and the specific field is the CSI activation PDCCH verification specific field. In this case, based on the above signaling, the terminal device determines that one of the four types of subconfigurations (the 8-port subconfiguration) is triggered / indicated / activated, and does not need to perform any processing for CSI activation.

[0152] In the case of triggering / indicating / activating a sub-configuration after SP-CSI activation, for example, the terminal device receives DCI 0_1. If the DCI format is scrambled by SP-CSI-RNTI, and the special fields in DCI Format 0_1 ​​are trigger / indicating / activating fields for the sub-configuration that are different from the semi-persistent CSI activation / deactivation PDCCH verification specific fields, and the newly defined first trigger / indicating / activating field (NES sub-CSI indication field) is a non-zero valid value, then the terminal device obtains the CSI reporting configuration index based on the CSI request area and triggers / indicates / activates the sub-configuration based on the newly defined first trigger / indicating / activating field (NES sub-CSI indication field). If the aforementioned CSI reporting setting was activated at a previous time using DCI scrambled by SP-CSI-RNTI, and a trigger / instruction / activation is performed on a sub-setting simultaneously with the CSI reporting activation, the trigger / instruction / activation information for the current sub-setting will overwrite the previous sub-setting trigger / instruction / activation information. Deactivation of the CSI or the next trigger / instruction / activation of the sub-setting represents a valid release / deactivation of the current sub-setting's trigger / instruction / activation information.

[0153] In the case of triggering / instructing / activating a sub-configuration after SP-CSI activation, for example, the terminal device receives DCI 0_1. If the DCI format is scrambled by a newly defined RNTI related to network energy saving, for example NES-RNTI, and the newly defined first trigger / instruction / activation field (NES sub-CSI indication field) is a non-zero valid value, the terminal device obtains the CSI reporting configuration index based on the CSI request area and performs the trigger / instruction / activation of the sub-configuration based on the newly defined first trigger / instruction / activation field (NES sub-CSI indication field). If the CSI reporting configuration was activated using DCI scrambled by SP-CSI-RNTI at a previous time, and the trigger / instruction / activation of the sub-configuration is performed simultaneously with the CSI reporting activation, the trigger / instruction / activation information for the current sub-configuration overwrites the previous sub-configuration trigger / instruction / activation information. Deactivating CSI or triggering / instructing / activating the next sub-configuration indicates a valid release / deactivation of the current sub-configuration's trigger / instruction / activation information.

[0154] In some embodiments, the terminal device receives a first DCI scrambled by SP-CSI-RNTI, the CSI request area of ​​the first DCI is associated with a semi-persistent CSI report having the same indicator as the CSI report setting, and the semi-persistent CSI report is activated using a previously received second DCI scrambled by SP-CSI-RNTI, in which case the first DCI is used to re-trigger / indicate / activate the sub-setting during the activation period of the semi-persistent CSI report.

[0155] In some embodiments, the current trigger / instruction / activation information for the sub-configuration overrides the previous trigger / instruction / activation for the sub-configuration, and after the semi-persistent CSI reporting is deactivated, the trigger / instruction / activation information for the sub-configuration is released / deactivated.

[0156] According to the provisions of the existing protocol, a UE is not expected to receive a DCI scrambled with SP-CSI-RNTI activating one semi-persistent CSI report with the same CSI-ReportConfigId as in a semi-persistent CSI report which is activated by a previously received DCI scrambled with SP-CSI-RNTI.

[0157] In the above embodiment, one UE can receive a DCI scrambled by SP-CSI-RNTI, the CSI request area of ​​the DCI is associated with a semi-persistent CSI report having the same CSI-ReportConfigId, and the semi-persistent CSI report is activated using a previously received DCI scrambled by SP-CSI-RNTI. The transmission act is not used for activating the semi-persistent CSI report, but rather for re-triggering / indicating / activating a sub-configuration of the CSI report activation period. This allows the DCI area triggering / indicating / activating mechanism to indicate multiple sub-configurations and multiple CSIs each time, providing high flexibility in indication, fewer bits in the DCI area, and low overhead.

[0158] In some embodiments, a CSI reporting configuration is associated with L CSIs, the CSI report includes S sub-configurations, e.g., sub-config 1 to sub-config L or codebook config 1 to codebook config L, where one sub-configuration corresponds to one CSI and S=L, the primary trigger / indicator / activation state list is the S sub-configurations of the CSI reporting configuration and X=S=L, the DCI format reuses the existing DCI format (0_1,0_2), the primary trigger / indicator / activation field of the DCI is a newly defined DCI area, the existing CSI-Semi PersistentOnPUSCH-TriggerStateList and CSI request field are used for activating / deactivating the CSI report, and the list of S sub-configurations and the primary trigger / indicator / activation field in the CSI reporting configuration are used for triggering / indicating / activating the sub-configurations.

[0159] In either case, the first trigger / indicator / activation field may be a codepoint with a bit width of log2X, where X is the number of trigger / indicator / activation states or the number of rows in the first trigger / indicator / activation state list, codepoint "0" or "1" is mapped to the trigger / indicator / activation state at the first position, and is mapped sequentially in the order arranged according to the ascending order of the trigger / indicator / activation state index in the first trigger / indicator / activation state list, or the first trigger / indicator / activation field (NES sub-CSI indication field) may be a bitmap with a bit width of X, where X is the number of trigger / indicator / activation states or the number of rows in the first trigger / indicator / activation state list, is arranged according to the ascending order of the trigger / indicator / activation state index in the first trigger / indicator / activation state list, and the MSB to LSB of the bitmap corresponds to the first to the last trigger / indicator / activation state.

[0160] The above provides an illustrative example of PUSCH's semi-persistent CSI reporting. For example, one set of trigger / indicator / activation states is a primary trigger / indicator / activation state list setting configured by the upper layer, of which the primary trigger / indicator / activation field in DCI is merged with the primary RNTI to trigger / indicate / activate at least one of the trigger states. According to the primary mapping scheme, the primary trigger / indicator / activation field in DCI is mapped to the trigger / indicator / activation state in the primary trigger / indicator / activation state list configured by the upper layer.

[0161] For example, the first trigger / instruction / activation state list is used to configure / instruct the CSI reporting settings and / or sub-settings of terminal equipment, each row in the first trigger / instruction / activation state list is one trigger / instruction / activation state, and there are a total of X rows, i.e., X trigger / instruction / activation states, each trigger state is associated with at least one CSI reporting setting and / or at least one sub-setting.

[0162] The first trigger / indicator / activation field in the DCI is merged with the first RNTI to trigger / indicate / activate at least one of its trigger states, in other words, to trigger / indicate / activate N1 sub-settings out of the CSI reporting setting and / or S sub-settings. The bit width of the first trigger / indicator / activation field is determined by the first trigger / indicator / activation size.

[0163] For the triggering / indication / activation of the PUSCH semi-persistent CSI sub-setting, the UE can verify the PDCCH on the DCI only when the following conditions are met: the CRC parity check bits of the DCI format are scrambled by the first RNTI provided by the upper layer, and / or the DCI format special area is the first special area setting.

[0164] If validation is successful, the UE considers the information in the DCI format to be a valid trigger / indication / activation and / or release / deactivation of the PUSCH semi-persistent CSI sub-configuration, and the UE triggers / indicates / activates or deactivates / releases the sub-configuration indicated by the first trigger / indication / activation field in the DCI. If validation fails, the UE considers that one mismatched CRC has been detected in the DCI format.

[0165] The following provides an illustrative example of the PUSCH non-periodic CSI report, omitting the explanation of the same content as above. For the second trigger / indication / activation state list, second trigger / indication / activation field, and second mapping method described below, please refer to the first trigger / indication / activation state list, first trigger / indication / activation field, and first mapping method described above.

[0166] For example, a set of trigger / instruction / activation states is a second trigger / instruction / activation state list setting configured by the upper layer, and of these, the second trigger / instruction / activation field in DCI triggers / instructs / activates at least one of the trigger states. According to the second mapping scheme, the second trigger / instruction / activation field in DCI is mapped to the trigger / instruction / activation state in the second trigger / instruction / activation state list configured by the upper layer.

[0167] In some embodiments, the secondary trigger / indication / activation state list for PUSCH non-periodic CSI reporting is an existing IE or a newly defined IE, and one trigger (indication / activation) state in the list is associated with at least one CSI reporting setting index and / or at least one sub-setting. That is, one trigger (instruction / activation) state in the list includes one associated report configuration list (associatedReportConfigInfoList) and one associated sub-configuration list (associated ReportConfigInfoList), or one trigger (instruction / activation) state in the list is associated with at least one CSI report configuration, that is, one trigger (instruction / activation) state in the list includes one associated report configuration list (associatedReportConfigInfoList), the report configuration list is at least one associated report configuration (associatedReportConfigInfo), one associated report configuration in the at least one associated report configuration is associated with at least one sub-configuration, that is, one associated report configuration in the at least one associated report configuration includes one associated sub-configuration list, for example, associatedSubConfigInfoList.

[0168] The second trigger / indicator / activation state list for PUSCH non-periodic CSI reporting is used to set up a set of trigger / indicator / activation states, where one trigger / indicator / activation state in the list is associated with at least one CSI reporting setting index and / or at least one sub-setting. Alternatively, one trigger (indicator / activation) state in the list is associated with at least one CSI reporting setting, i.e., one trigger (indicator / activation) state in the list includes associated related reporting setting information, where the associated reporting setting information may be associated with at least one sub-setting, i.e., the associated reporting setting information includes one associated sub-setting list.

[0169] In some embodiments, the second trigger / indicator / activation state list for PUSCH non-periodic CSI reporting consists of S sub-configurations in the CSI reporting configuration, where each trigger / indicator / activation state in the list is one sub-configuration, of which X=S, for example, sub-config 1 to sub-config S or codebook config 1 to codebook config S in the CSI reporting configuration consists of S sub-configurations.

[0170] In some embodiments, the second trigger / indication / activation state list for PUSCH aperiodic CSI reporting may reuse an existing IE, e.g., CSI-AperiodicTriggerStateList, or it may be a newly defined IE, e.g., CSI-AperiodicTriggerStateList-r18, where each trigger state may be associated with at least one CSI reporting setting and / or at least one sub-setting. Alternatively, one trigger (indication / activation) state may be associated with at least one CSI reporting setting, i.e., one trigger (indication / activation) state in the list may include associated information on at least one related reporting setting, and the related reporting setting information may be associated with at least one sub-setting, i.e., the related reporting setting information includes a list of related sub-settings.

[0171] The aforementioned sub-setting information may be sub-setting (index), codebook setting (index), port subset instruction information (index), n1-n2 setting (index), etc., and each sub-setting related parameter is associated with one spatial domain / energy domain adjustment element mode.

[0172] Table 8 shows one example of a trigger / indication / activation state list for PUSCH aperiodic CSI reporting.

[0173] [Table 8] TIFF2026516474000010.tif68161 For example, the first trigger / indicator / activation state list based on PUSCH semi-persistent CSI reports and the second trigger / indicator / activation state list based on PUSCH aperiodic CSI reports may be the same list; that is, one list contains both semi-persistent CSI report information and aperiodic CSI report information.

[0174] In some embodiments, the DCI's second trigger / indicator / activation field is used to indicate at least one trigger / activation / state in the second trigger / indicator / activation state list set by the RRC, and is used for activating / deactivating and / or triggering / indicating / activating sub-settings of CSI reports.

[0175] For example, an existing DCI format (0_1,0_2) can be reused, and an existing DCI area (CSI request) can be reused, with the second trigger / indicator / activation field of the DCI being the CSI request area.

[0176] Furthermore, for example, the DCI's second trigger / indication / activation field is a newly defined DCI area. The existing CSI request area is used for activating / deactivating CSI reports, while the newly defined DCI area is used for triggering / indicating / activating sub-configurations.

[0177] Furthermore, for example, the first trigger / indication / activation field of DCI based on PUSCH semi-sustained CSI reporting and the second trigger / indication / activation field of DCI based on PUSCH aperiodic CSI reporting may be in the same DCI region, that is, distinguished by scrambling by different RNTIs, being aperiodic CSI reporting when scrambling by C-RNTI and semi-sustained CSI reporting when scrambling by SP-CSI-RNTI, or the first trigger / indication / activation field of DCI based on PUSCH semi-sustained CSI reporting and the second trigger / indication / activation field of DCI based on PUSCH aperiodic CSI reporting may be in different DCI regions. In some embodiments, the second trigger / indication / activation state list set by the RRC is an existing IE (e.g., CSI-AperiodicTriggerStateList) or a newly defined IE (e.g., CSI-AperiodicTriggerStateList-r18), and one trigger / indication / activation state in the list is associated with at least one CSI reporting setting and / or at least one sub-setting, i.e., some trigger / indication / activation states in the list are associated only with the CSI reporting setting index, and other trigger / indication / activation states are associated with the CSI reporting setting index and / or sub-settings, and an existing DCI format (0_1,0_2) may be reused, the second trigger / indication / activation field of the DCI is a CSI request field or a newly defined DCI area (e.g., CSI request field-r18), and the second trigger / state / indication state list and the second trigger / indication / indication field are used for activating CSI reporting and triggering / indicating / activating sub-settings. The newly defined second trigger / instruction / activation field has a bit width of log2X, where codepoint "0" or "1" is mapped to the trigger / instruction / activation state at the first position, where X is the number of trigger / instruction / activation states or the number of rows in the first trigger / instruction / activation state list.

[0178] When AP-CSI is activated, for example, the terminal device receives DCI 0_1. The newly defined DCI field (NES sub-CSI indication field) is all zeros or invalid values, in which case the terminal device determines the CSI report that needs to be activated based on the CSI request field.

[0179] When AP-CSI is activated and a sub-configuration is triggered / instructed / activated, for example, the terminal device receives DCI 0_1. The newly defined DCI field (NES sub-CSI indication field) is a valid non-zero value, in which case the terminal device activates semi-persistent CSI reporting based on the CSI reporting configuration index corresponding to the CSI request field, and also triggers / instructs / activates the sub-configuration based on the newly defined DCI field (NES sub-CSI indication field).

[0180] In some embodiments, for example, RRC sets a second trigger / indication / activation state list, the list being a newly defined IE, e.g., CSI-Aperiodic-subConfig-TriggerStateList or NES-sub-CSI-Aperiodic OnPUSCH-TriggerStateList, where two trigger / indication / activation states in the list are associated with a CSI reporting configuration index and / or at least one subconfiguration, and RRC sets CSI-AperiodicOnPUSCH-TriggerStateList, DCI Format reuses the existing DCI format (0_1,0_2), the second trigger / indication / activation field of the DCI is a newly defined DCI area, the existing CSI-AperiodicOnPUSCH-TriggerStateList and CSI request field are used for CSI reporting activation, and the second trigger / indication / activation state list and second trigger / indication / activation field are used for subconfiguration trigger / indication / activation. In either case, the second trigger / indicator / activation field may be a codepoint with a bit width of log2X, where X is the number of trigger / indicator / activation states or the number of rows in the first trigger / indicator / activation state list, codepoint "0" or "1" is mapped to the trigger / indicator / activation state at the first position, and is mapped sequentially in the order arranged according to the ascending order of the trigger / indicator / activation state index in the second trigger / indicator / activation state list, or the second trigger / indicator / activation field (NES sub-CSI indication field) may be a bitmap with a bit width of X, where X is the number of trigger / indicator / activation states or the number of rows in the first trigger / indicator / activation state list, is arranged according to the ascending order of the trigger / indicator / activation state index in the second trigger / indicator / activation state list, and the MSB to LSB of the bitmap corresponds to the first to the last trigger / indicator / activation state.

[0181] When AP-CSI is activated, for example, the terminal device receives DCI 0_1. The newly defined DCI field (NES sub-CSI indication field) is all zeros or invalid values, in which case the terminal device determines the CSI report that needs to be activated based on the CSI request field.

[0182] When AP-CSI is activated and a sub-configuration is triggered / instructed / activated, for example, the terminal device receives DCI 0_1. The newly defined DCI field (NES sub-CSI indication field) is a valid non-zero value, in which case the terminal device activates semi-persistent CSI reporting based on the CSI reporting configuration index corresponding to the CSI request field, and also triggers / instructs / activates the sub-configuration based on the newly defined DCI field (NES sub-CSI indication field).

[0183] In some embodiments, a CSI reporting configuration is associated with L CSIs, the CSI report includes S sub-configurations, e.g., sub-config 1 to sub-config L or codebook config 1 to codebook config L, where one sub-configuration corresponds to one CSI and S=L, the second trigger / indication / activation state list is the S sub-configurations of the CSI reporting configuration and X=S=L, the DCI format reuses the existing DCI format (0_1,0_2), the second trigger / indication / activation field of the DCI is a newly defined DCI area, the existing CSI-AperiodicOnPUSCH-TriggerStateList and CSI request field are used for activating the CSI report, and the list of S sub-configurations and the second trigger / indication / activation field in the CSI reporting configuration are used for triggering / indicating / activating the sub-configurations. In either case, the second trigger / indicator / activation field may be a codepoint with a bit width of log2X, where X is the number of trigger / indicator / activation states or the number of rows in the first trigger / indicator / activation state list, codepoint "0" or "1" is mapped to the trigger / indicator / activation state at the first position, and is mapped sequentially in the order arranged according to the ascending order of the trigger / indicator / activation state index in the first trigger / indicator / activation state list, or the second trigger / indicator / activation field (NES sub-CSI indication field) may be a bitmap with a bit width of X, where X is the number of trigger / indicator / activation states or the number of rows in the second trigger / indicator / activation state list, is arranged according to the ascending order of the trigger / indicator / activation state index in the second trigger / indicator / activation state list, and the MSB to LSB of the bitmap corresponds to the first to the last trigger / indicator / activation state.

[0184] When AP-CSI is activated, for example, the terminal device receives DCI 0_1. The newly defined DCI field (NES sub-CSI indication field) is all zeros or invalid values, in which case the terminal device determines the CSI report that needs to be activated based on the CSI request field.

[0185] When AP-CSI is activated and a sub-configuration is triggered / instructed / activated, for example, the terminal device receives DCI 0_1. The newly defined DCI field (NES sub-CSI indication field) is a valid non-zero value, in which case the terminal device activates semi-persistent CSI reporting based on the CSI reporting configuration index corresponding to the CSI request field, and also triggers / instructs / activates the sub-configuration based on the newly defined DCI field (NES sub-CSI indication field).

[0186] The following explains the case of group-wide signaling.

[0187] In some embodiments, the downlink control information (DCI) is group common signaling, and the downlink control information is scrambled by a second RNTI. The group common signaling includes multiple blocks, each corresponding to one terminal device. The group common signaling is used to trigger / instruct / activate a sub-configuration of at least one terminal device.

[0188] In some embodiments, the block is used to indicate the CSI reporting setting index of the terminal device and / or at least one sub-setting. In the block, a codepoint or a bitmap is used to indicate the sub-setting, and the number of bits / positions corresponds in order to the trigger (indication / activation) state. The bit width of the block is related to the number of sub-settings of the terminal device and / or the bit width of the CSI reporting setting index.

[0189] For example, DCI Format 2_X is used to notify the sub-setting information of N out of L sub-settings in one or more terminal device CSI reports, where N < L, each sub-setting is associated with one CSI, and the terminal device reports N CSIs based on DCI Format 2_X.

[0190] For example, the following information adopts DCI Format 2_X, and the CRC is scrambled and transmitted by a second RNTI (e.g., nes-RNTI), that is, Block 1, Block 2,..., Block N.

[0191] In some embodiments, the second RNTI is determined based on a first parameter, the size of the valid payload of the downlink control information is determined by a fourth parameter, the start position of the corresponding block information in the downlink control information (DCI) of the terminal device is determined by a second parameter, the bit width of the corresponding block in the downlink control information (DCI) of the terminal device is determined based on a third parameter, and the bit width of the CSI reporting setting index of the terminal device is determined based on a fifth parameter.

[0192] For example, the starting position of a block is determined by a second parameter (e.g., nes-PositionDCI-2-6) set by the upper layer for the terminal device. When the terminal device is configured with a second RNTI (e.g., nes-RNTI) and dci-Format2-X by the upper layer parameters, the upper layer sets up one block for the terminal device, and the field contents of that block include at least one of the following: -CSI reporting setting index-Ybit, where Y is determined by a predefined set, for example, Y=2, or the size of Y is determined using the fifth parameter of the upper layer; and - This is a trigger / instruction / activation instruction for a sub-setting. The bit width of the bitmap is determined based on the third parameter of the higher layer, where each bit corresponds to one sub-setting and is arranged in ascending order according to the sub-setting index in the CSI reporting settings. The MSB to LSB of the bitmap corresponds to the first to last setting. Of these, 1 represents activation and 0 represents deactivation.

[0193] The size of DCI Format 2_X is indicated by a fourth parameter in the upper layer (e.g., sizeDCI-2-X). DCI Format 2_X is used by terminal equipment to monitor DCI Format 2_X, for example, the DCI Format 2_X is related to network energy saving and / or to a CSI reporting configuration that includes L sub-configurations, where X may be a positive integer greater than 6.

[0194] In some embodiments, the first parameter is the RNTI value for scrambling the CRC of DCI Format 2-X for network energy saving; the second parameter is the starting position of the CSI reporting setting index and / or sub-setting trigger / indicator / activation indicator in DCI Format 2-X; the third parameter is used to indicate the bit width of the sub-setting trigger / indicator / activation indicator information, i.e., the number of sub-settings, where each bit corresponds to one sub-setting; the fourth parameter is used to indicate the size of DCI Format 2_X; and the fifth parameter is used to determine the size of Y mentioned above.

[0195] In some embodiments, terminal devices with network energy saving functions enabled can detect DCI format 2_X upon PDCCH reception. For example, the terminal device determines the RNTI of DCI format 2_X based on the first parameter, monitors the DCI format 2_X on the active DL BWP of the PCell or SpCell by monitoring the PDCCH using DCI format 2-X, determines the size of the valid payload of DCI format 2_X based on the fourth parameter, determines the position of the terminal device's information in DCI format 2_X based on the second parameter, determines the size of Y based on the fifth parameter or a predefined rule, the Y bits are used to determine the CSI reporting setting index, the fifth parameter determines that when the value of Y is equal to 0, there is no CSI reporting setting index information in the current DCI format, and determines the bit width of the bitmap based on the third parameter, i.e., determines the number of sub-settings in the CSI reporting setting. The bitmap is located after the CSI reporting settings index information (if the CSI reporting settings index information is set), the size of the bitmap is equal to the number of sub-settings, each bit corresponds to one sub-setting, a 1 in the bitmap indicates activation of the sub-setting, and a 0 indicates deactivation.

[0196] The following describes the case of PUCCH semi-persistent CSI reporting, and the description of the same content as above is omitted. For the following third trigger / indication / activation state list, etc., the aforementioned first trigger / indication / activation state list can be referred to.

[0197] In some embodiments, the channel state information (CSI) report configuration is for physical uplink control channel (PUCCH) semi-persistent CSI reporting. The indication information is a medium access control (MAC) control element (CE), and the MAC CE activates or deactivates at least one sub-configuration among the plurality of sub-configurations.

[0198] For example, the trigger / indication / activation MAC CE of the sub-configuration of the PUCCH semi-persistent CSI reporting configuration may be identified by a MAC sub-header with one LCID. For example, there is one fixed bit width, and the size of the bit width is the first bit width parameter, including the following fields, namely, - Service cell ID: This field represents the identifier of the service cell to which the MAC CE is applied. The field length is 5 digits; - BWP ID: This field represents the UL BWP to which the MAC CE is applied and is the code point of the DCI bandwidth part indication field. The BWP ID field length is 2 digits; -S i : Represents the activation and release / usage stop / deactivation states of the trigger / indication / activation of the sub-configuration in the third trigger / indication / activation list of the semi-persistent CSI report carried by PUCCH. S0 indicates the sub-configuration and has the lowest CSI-ReportConfigId in the third trigger / indication / activation list, S1 indicates the sub-configuration and has the second lowest CSI-ReportConfigId in the third trigger / indication / activation list, and the others can be analogized based on this. When the number of sub-configurations in the third trigger / indication / activation list is smaller than i + 1, the MAC entity ignores the S i field. S iSetting the field to 1 indicates that the sub-setting of the corresponding semi-persistent CSI reporting setting is triggered / indicated / activated. i Setting a field to 0 indicates that the sub-setting of the corresponding semi-persistent CSI reporting setting is released / disabled / deactivated; and -R: This is a spare digit and is set to 0.

[0199] The first bit width parameter may be determined by a predefined method, for example, the first bit width parameter = X, where X = 16, or the first bit width parameter may be determined by the RRC upper layer parameter.

[0200] In some embodiments, the RRC configures a third trigger / indicator / activation list, where each row in the third trigger / indicator / activation list corresponds to one CSI reporting settings index and / or at least one CSI-RS resource index or at least one sub-setting.

[0201] For example, the third trigger / indicator / activation state list for PUCCH semi-persistent CSI reporting consists of S sub-configurations in the CSI reporting configuration, where each row in the list is one sub-configuration, and where X=S, for example, sub-config 1 to sub-config S or codebook config 1 to codebook config S in the CSI reporting configuration consists of S sub-configurations.

[0202] Furthermore, for example, the third trigger / instruction / activation state list for PUCCH semi-persistent CSI reporting reuses an existing IE, e.g., CSI-reportconfigtoaddmodlist or some CSI-reportconfigtoaddmodlist, where each row in the list is at least one sub-configuration and X=S.

[0203] Furthermore, for example, the trigger / instruction / activation (state) list for PUCCH semi-persistent CSI reporting is a newly defined IE, e.g., NES-sub-CSI-SemipersistentOnPUCCHList, where each row may be one sub-setting and X=S.
