Description

Technical Field

[0001] This application claims priority to Chinese Patent Application No. 202111414184.2, titled "Method and Apparatus for Channel State Information (CSI) Reporting", filed with the China National Intellectual Property Administration on November 25, 2021, which is hereby incorporated by reference in its entirety into this document.

Background Art

[0003] 5G (5th Generation) communication systems impose higher requirements on system capacity, spectral efficiency, and other aspects. In the case of an FDD (Frequency-Division Duplexing) Massive MIMO (Multiple Input Multiple Output) system, obtaining downlink CSI (Channel State Information) is one of the important factors for ensuring the operation of the system. For example, a base station requires CSI for reconfiguring downlink channels and precoding matrices. Different from a TDD (Time-Division Duplexing) system, in an FDD system, there is a large frequency interval between the uplink channel and the downlink channel, and the uplink channel and the downlink channel are not completely reciprocal. As a result, an FDD system cannot obtain a complete downlink channel through uplink channel estimation. This is not possible. In conventional FDD systems, terminal devices use the CSI of the downlink channel. We need to provide feedback to the local authorities.

[0004] However, terminal devices only support one type of CSI reporting. Flexibility of CSI reporting To improve this, the trigger mechanism for CSI reporting needs to be redesigned. [Overview of the Initiative]

[0086] The protocol randomly combines three types of CSI-RS resource delivery and CSI reporting. Please note that they cannot be combined. Combinations of CSI-RS resource delivery and CSI reporting types. The combinations are shown in Table 1.

[0087] [Table 1]

[0088] Below, with reference to Figures 3, 4, and 5, we will discuss three types: periodic, semi-permanent, and This section will specifically explain the meanings of "periodic" and "non-periodic."

[0089] Figure 3 is a schematic diagram of the coordination process between semi-persistent CSI-RS distribution and semi-persistent CSI reporting.

[0090] More specifically, the process shown in Figure 3 involves semi-persistent CSI-RS delivery and semi-persistent CSI-RS delivery in PUSCH. This is an example of a persistent CSI report.

[0091] As shown in Figure 3, the collaborative process includes the following steps.

[0095] Specifically, the first MAC-CE message triggers CSI-RS resource distribution. This is the case. As an optional choice, the first MAC-CE message is CSI-RS resource The first MAC-CE message indicates the configuration information for the CSI-RS resource. This triggers CSI-RS resource distribution by default.

[0096] Specifically, semi-persistent CSI-RS delivery triggers or turns on CSI-RS resource delivery. The first MAC-CE message to enable the first CSI-RS resource distribution, and then The CSI-RS resource cycles based on the period configured using the first MAC-CE message. CSI-RS resources, which are delivered regularly and periodically, use separate MAC-CE messages. It does not need to be turned on by the network device turning off CSI-RS resource distribution. Until you turn off CSI-RS resource distribution using the second MAC-CE message, CSI -This means that the periodic delivery of RS resources will cease.

[0097] 3. The network device uses the first downlink control information DCI to perform CSI reporting. Turn on your terminal device to perform the action.

[0098] Specifically, the first DCI is intended to trigger a CSI report. (Optional) The first DCI will provide the CSI reporting configuration information. This instruction means that CSI reporting will be triggered by default.

[0099] Specifically, semi-persistent CSI reporting is the first step in triggering or turning on CSI reporting. The first CSI report is turned on using the DCI message, and then the first DCI is used Based on the configured period, CSI reports are submitted periodically, and the periodically submitted CSIs are separate. It does not need to be turned on using DCI messages, and network devices do not need to report CSI The periodic CSI will continue until you turn off the CSI reporting using the second DCI message to turn it off. This means that reporting will stop.

[0100] Specifically, this relates to CSI reporting configuration information or fields included in the first DCI. The details are shown in Figure 4. Figure 4 shows the configuration information for semi-persistent CSI-RS based semi-persistent CSI reporting. This is a schematic diagram of the configuration process.

[0102] To be more specific, the first DCI is for turning on CSI reporting. The first DCI turns on CSI reporting by instructing the CSI reporting configuration information. In other words, The terminal device then receives the first DCI and, through the instructions within the first DCI, receives the CSI report configuration information. Obtaining the information and CSI reporting configuration information means that CSI reporting is turned on by default. do.

[0103] In this embodiment of the present application, turning on CSI reporting triggers CSI reporting. Please note that it may also be called by this name. As long as the meaning of the expression is the same, this name is the original This embodiment of the application is not specifically limited.

[0104] Specifically, the CSI Request field uses the codepoint configuration. And in the semiPersistentOnPUSCHTriggerStateList It is associated with the trigger state.

[0105] The CSI Request field can occupy up to 6 bits, and the upper layer parameter reporting trigger size Note that it is configured using (reportTriggerSize). 6 bits is semiPers istentOnPUSCH-TriggerStateList can be associated with up to 64 different trigger states, and further It can be associated with 64 types of CSI reporting configuration information.

[0106] As an example, not an exhaustive one, if the CSI Request field has 6 bits that are 000000, The corresponding value can be 0. In this case, the CSI Request field is sem by codepoint. Trigger State 1 in iPersistentOnPUSCHTriggerStateList may be associated with TriggerState 1 The semiPersistentOnPUSCHTriggerStateList contains a correspondence between bit values ​​and trigger states. Please note that this is applicable.

[0107] Specifically, it relates to each TriggerState in semiPersistentOnPUSCHTriggerStateList. The CSI-ReportConfigId (CSI-ReportConfigId) of the attached CSI report configuration information is CSI-Repo The rtConfigId is used to associate the CSI reporting configuration information CSI-ReportConfig. tConfig specifically includes the CSI reporting cycle (ReportSlotConfig) and the CSI reporting time domain offset. ReportSlotOffsetList, CSI-RS Resource Configuration This includes, among others.

[0108] Specifically, the first DCI is Time Domain Resource Allocation. The ssignment field further includes the Time domain resource assignment field. Using the codepoint configuration, isolate one of the aforementioned reportSlotOffsetLists, Determine the time domain offset of the CSI report based on the values ​​in the list. Optionally, the time domain can be selected. The region offset is the sum of n slots after DCI has been received in the slot. Often, that slot is when the first CSI report is executed.

[0109] According to the steps described above, the following CSI report configuration information is obtained, namely, the time domain of the CSI report. You can obtain the header, CSI-RS resource configuration, and CSI reporting cycle.

[0110] If the CSI report is a semi-permanent CSI report on PUCCH, use MAC-CE message CS Please note that reporting needs to be turned on or triggered. This is optional. The CSI report configuration information is indicated using MAC-CE information.

[0111] In this embodiment of the present application, a CSI report on PUSCH is used as an example for illustrative purposes. Please note that the method steps of this embodiment of the present application are also suitable for CSI reporting on PUCCH. This may be used. This is not limited to the present embodiment of this application.

[0112] 4. The terminal device performs CSI reporting based on the configuration of the first DCI.

[0113] The terminal device has time domain offset in the CSI reporting configuration information configured using the first DCI. Perform the first CSI report based on the first DCI, and then perform the CSI report configured using the first DCI. Please understand that CSIs will be reported periodically based on the reporting cycle in the notification configuration information.

[0114] 5. The network device sends a second DCI to the terminal device to turn off CSI reporting. I believe.

[0115] 6. The network device uses the second MAC-CE message to turn off CSI-RS distribution. To do this, a notification is sent to the terminal device.

[0116] Figure 5 is a schematic diagram of the configuration process for configuration information of semi-persistent CSI-RS-based non-periodic CSI reporting. As shown in Figure 5, non-periodic CSI reporting is enabled or disabled using a third DCI. The trigger is activated, and the specific steps are similar to those shown in Figure 3.

[0117] Specifically, the third DCI is DCI format 0_1 ​​or DCI format 0_2 information. Often, the third DCI also includes the CSI Request field.

[0118] Specifically, the CSI Request field is a non-periodic trip by the configuration of the codepoint. Associated with the trigger state TriggerState in the state list aperiodicTriggerStateList. .

[0119] Note that the specific description of the CSI Request field is the same as the description corresponding to Figure 4. Please do so. In this embodiment of the present application, further details will not be described again here.

[0120] Unlike the configuration of semi-persistent CSI reports, the CSI Request field is 6 bits of 000000. If it has a corresponding value that can be 0, it means that the CSI report will not be performed. Alternatively, if 6 bits are 000001 and the corresponding value can be 1, the CSI Request field The codepoint sets the trigger state 1 in aperiodicTriggerStateList to TriggerState 1. Please pay particular attention to the possible connections.

[0121] The process of associating TriggerState with CSI-ReportConfigId corresponds to Figure 4. Please note that this is the same as described. In this embodiment of the present application, further details are provided here. I will not explain further. Use CSI-ReportConfigId to enter the CSI Request fee into CSI-ReportConfig. Please note that "Rudo" may be associated with this.

[0122] Specifically, CSI-ReportConfig is a CSI reporting time domain offset. (reportSlotOffsetList), CSI-RS resource configuration list CSI-RS-ResourceSetList This includes, etc. Similar to the explanation in Figure 4, the third DCI is Time Domain Resource Allocation (Tim The field further includes Time domain resource assignment. The nment field is one of the reportSlotOffsetList using the codepoint configuration. Separate one value and determine the time domain offset of the CSI report in the list.

[0123] Specifically, TriggerState further includes the resource configuration value ResourceSet, and CSI- Resources within RS-ResourceSetList are associated using ResourceSet, which means that this time This is the CSI-RS resource configuration CSI-RS-ResourceSet for the CSI report.

[0124] According to the steps described above, the following CSI report configuration information is obtained, namely, the time domain of the CSI report. You can obtain the header and CSI-RS resource configuration.

[0125] In some embodiments, the configuration process is based on the contents included in the CSI report configuration information. Therefore, it can be determined that the type of CSI report is an aperiodic CSI report.

[0126] Specifically, non-periodic CSI reporting uses a third DCI to turn on CSI reporting. This means that CSI reporting was turned on only once, and there have been no periodic CSI reports since then.

[0127] Refer to the relevant explanations in Figures 3, 4, and 5 for semi-persistent CSI-RS resource delivery, semi-permanent Continuous CSI reporting and aperiodic CSI reporting are described below. This section briefly explains source distribution, periodic CSI-RS resource distribution, and periodic CSI reporting. .

[0128] Aperiodic CSI-RS resource distribution is similar to aperiodic CSI reporting, and this is the network The device uses a third MAC-CE message to turn on CSI-RS distribution only once, and then Please understand that this means there will be no periodic CSI-RS broadcasts.

[0129] Periodic CSI-RS resource distribution and periodic CSI reporting are performed using DCI or MAC-CE messages. It does not need to be turned on, and it has a preset period and a preset time domain offset. Please understand that periodic distribution or reporting will be necessary based on this.

[0130] By sending downlink control information once, one CSI report or one type of CSI is generated. As explained above, it is possible to trigger or turn on reporting only.

[0131] Figure 6 is a schematic diagram of an example of a method for triggering a CSI report according to one embodiment of this application. As shown in 6, method 600 includes the following steps:

[0132] S610: The network device transmits downlink control information to the terminal device.

[0133] Accordingly, terminal devices receive downlink control transmitted by network devices. Receive information.

[0134] Specifically, the downlink control information is used to trigger N CSI reports. The downlink control information is for turning on N CSI reports, where N is 1 or less. It is a large positive integer.

[0135] In other words, downlink control information is used to trigger multiple CSI reports. .

[0136] In some embodiments, downlink control information indicates N CSI reporting configuration information, N CSI report configuration information entries correspond one-to-one with N CSI reports.

[0137] As an optional choice, the downlink control information instructs N CSI reporting configuration information. This means that N CSI reports are triggered or turned on.

[0138] In other words, the terminal device receives downlink control information, and the downlink control information Based on the instructions, obtain N CSI report configuration information. This is because N CSI reports are by default This means that it is triggered or turned on. Furthermore, the CSI report contains the corresponding CSI report configuration information. It is executed using the report.

[0139] To be more specific, the contents of the CSI report configuration information are: Reporting cycle, time domain offset, measurement resources, and reporting content. It includes one or more of the following.

[0140] The contents of the N CSI report configuration information items are all different, and can be chosen arbitrarily. Therefore, at least one of the contents of the N CSI report configuration information items is different.

[0141] Specifically, the reporting cycle may be the same as the semi-permanent CSI reporting cycle described above.

[0142] As an optional choice, N CSI reports are multiple semi-permanent CSI reports with different reporting cycles. It may include.

[0143] As an optional step, the step of determining the reporting cycle is the semi-permanent CSI reporting described above. This may be a step to determine the reporting cycle.

[0144] As an optional step, the step for determining the reporting cycle can instead be reset. Other decision steps may also be possible.

[0145] As an optional feature, the reporting cycle can be set to ReportSlotConf, in accordance with existing protocols. It may be configured using ig.

[0146] Specifically, the time domain offset is the time domain offset of the semi-persistent CSI report mentioned above. It may be a set, or the time domain offset is the time domain of the aperiodic CSI report described above. A regional offset is also acceptable.

[0147] As an optional step, the step of determining the time-domain offset is the semi-permanent step described above. This may be a step in determining the time domain offset of a periodic or nonperiodic CSI report.

[0148] As an optional step, the step of determining the time-domain offset can instead be, Other decision steps may also be included.

[0149] As an optional choice, the time-domain offset is, in accordance with existing protocols, repo It may also be configured using rtSlotOffset.

[0150] Specifically, the measurement resources are the CSI-RS resource configuration for the semi-persistent CSI reporting mentioned above. It may be, or the measurement resources may be the CSI-RS resource configuration for the aperiodic CSI report described above. That's fine.

[0151] As an optional choice, determining the measurement resources is related to the semi-permanent CSI reporting mentioned above. Alternatively, this may involve determining the CSI-RS resource configuration for non-periodic CSI reporting.

[0152] As an optional step, the step of determining the measurement resources is instead reset. Other decision-making steps may also be taken.

[0153] As an optional choice, in accordance with existing protocols, the measurement resources are (semi-persistent) CSI-RS resource Config (for CSI reporting) or CSI (for non-periodic CSI reporting) -RS-ResourceSet may be used for configuration.

[0154] To be more specific, the report content is the same as that of the CSI report.

[0155] As an optional choice, the structure of the CSI report content is one bit within the downlink control information. The report content may be completed using the instruction field.

[0156] As an optional choice, the structure of the CSI report content is related to downlink control information. This may be completed using the 1-bit reporting content indicator field within the attached trigger state. .

[0157] As an optional choice, the structure of the CSI report content can be configured using other configurations in CSI-ReportConfig. It may be configured using the parameter, reportQuantity. Specifically, If reportQuantity is set to "cri-RI-PMI-CQI", the terminal device will default Short-term reports are submitted via the platform, and the report contents include RI (Rank Indicator) and PMI (Precode). ng Matrix Indicator (precoding matrix indicator), and CQI (Channel Quality Indicator). This includes dicators (channel quality indicators). Optionally, the reporting content can be CRI (CSI). -Includes RS Resource Indicator (CSI-RS resource indicator). reportQuantity is " If set to "cri-PMI", the terminal device will perform long-term reporting by default, and within the report The content is PMI. Optionally, the reporting content may also include CRI.

[0158] As an example, not an limitation, this embodiment of the present application reflects differences in the naming of the reported content. Therefore, two types of CSI reports with different reporting content are called long-term CSI reports and short-term CSI reports, respectively. (This book uses two types of report content as examples for explanation, but there are three or more types.) (If there is a report, a different name may be used.)

[0159] The name is merely for the purpose of facilitating description and distinction, and the name is used in this embodiment of the present application. Please understand that it is not limited.

[0160] In this embodiment of the present application, long-term semi-permanent CSI reporting, short-term semi-permanent CSI reporting, and short-term This section primarily explains aperiodic CSI reporting.

[0161] It should be understood that there may be other combinations of CSI reports. This is not limited to this implementation form of the present application.

[0162] Optionally, the 1-bit report content can indicate a name corresponding to the report content .

[0163] Corresponding to the above example, the 1-bit report content indication field can indicate whether the CSI report is long-term or short-term , and the terminal device determines the report content by default.

[0164] For example, if the 1-bit value corresponding to the report content indication field is 0, it means a long-term report . If the 1-bit value corresponding to the report content indication field is 1, it means a short-term report . The terminal device reports based on the report content corresponding to long-term and short-term.

[0165] Optionally, the 1-bit report content indication field can indicate the specific report content of the CSI report .

[0166] Since some of the report content of the preceding CSI report can provide basic information for the subsequent CSI report, it should be noted that the accuracy of pre-coding matrix reconstruction or channel reconstruction performed by the network device is improved.

[0167] In this embodiment of the present application, the report content of the long-term CSI report is preferentially set to provide measurement information for the short-term CSI report .

[0168] Therefore, in some implementations, in order to provide basic information for the short-term CSI report, ​​By configuring a time-domain offset, the reporting time of the long-term CSI report is the same as the reporting time of the short-term CSI report. It will be set to occur earlier than the notification time.

[0169] For example, DCI can trigger both long-term semi-permanent CSI reporting and short-term semi-permanent CSI reporting simultaneously. In this case, the network device, during configuration, has a time domain offset for short-term semi-permanent CSI reporting. This constitutes a time-domain offset for long-term semi-permanent CSI reports that falls short of the specified time.

[0170] As another example, DCI can simultaneously track both long-term semi-permanent CSI reports and short-term aperiodic CSI reports. If this occurs, the network device will turn off the time domain of short-term non-periodic CSI reporting during configuration. This constitutes a time-domain offset for long-term semi-permanent CSI reports that do not meet the requirements for a set.

[0171] As an optional choice, in the case of semi-permanent CSI reporting, long-term refers to long-term semi-permanent CSI reporting. This can mean a long reporting cycle, while "short" refers to a short reporting cycle for short-term semi-permanent CSI reports. This could mean...

[0172] As an optional choice, "long term" means that the reported content must be measured over a long period of time. It could mean that, as an optional choice, it needs to be measured for the purpose of reporting. The measured quantity may change slowly. Short term, on the other hand, means that the reported content is measured in the short term. This could mean that it is necessary to measure for the content of the report. The required measurement quantity can change rapidly.

[0173] Therefore, reports that address long-term needs to be submitted once over a long period, and short-term reports need to be submitted once over a long period. The corresponding reports must be submitted at least once in a short period of time.

[0174] Note that the long or short term can be relative to the period.

[0175] For example, when the long term and the short term correspond to the reporting period of semi-persistent CSI reports, a period threshold is set If the reporting period of the semi-persistent CSI report exceeds the period threshold, the period is long. If the reporting period of the semi-persistent C SI report does not exceed or is equal to the threshold, the period is short. <00,00952>

[0176] By way of example and not limitation, the report content indication field may be combined with the configuration of reportQuantity to determine the report content.

[0177] For example, in the case of a spatial frequency joint-based CJT (Coherent Joint Transmission) transmission solution, when reportQuantity is set to "cri-RI-PMI-CQ I" to indicate a long-term CSI report, the terminal device reports information regarding the spatial frequency joint base, and when reportQuantity is set to "cri-RI-PMI-CQI" to indicate a short-term C<, SI report, the terminal device reports the superimposed coefficient information. For example, when information regarding the spatial frequency joint base is reported in a long-term CSI report, the short-term CSI report obtains and reports the superimposed coefficient information based on the spatial frequency joint base reported in the long-term CSI report, so that the reported superimposed coefficient is more accurate.

[0178] According to the method provided in this embodiment of the present application, both the long-term CSI report and the short-term CSI report are

[0179] ​​​When triggered or turned on simultaneously, the contents of the first reported long-term CSI will be the same as the contents of the short-term CSI report. We can provide some information for that purpose. You can choose which information to use; this information is basic information. As a result, precoding matrix reconstruction or The accuracy of channel reconstruction improves.

[0180] In this embodiment of the present application, the CSI reporting configuration described in Figures 3, 4, and 5 is The decision-making step serves as the basis for improvements to achieve the solution of this embodiment of the present application. Please note that this is used as an example to illustrate a solution. To use.

[0181] To the extent that the solution of this embodiment of the present application can be achieved, the reporting structure of the CSI report is determined. It is understood that other reset steps are within the scope of protection of this embodiment of the present application. This is not specifically limited to this embodiment of the present application.

[0182] As an example, not an exhaustive one, if N is 2, then the two CSI reports are each long-term semi-permanent CSIs. Let's assume there are reports and short-term / semi-permanent CSI reports.

[0183] The solution of this embodiment of the present application will be described below with reference to Figure 7, using an example.

[0184] Figure 7 shows a configuration of long-term semi-permanent CSI reporting and short-term semi-permanent CSI reporting according to one embodiment of this application. This is a schematic diagram of an example of the process. As shown in Figure 7, this process is as follows: This includes the following steps.

[0185] This process further includes downlink control information to turn off CSI reporting. In the process description, downlink control information for turning on or triggering CSI reporting The report is downlink control information included in method 600, which is the first downlink control The first DCI is limited to information and optional. It is used to turn off CSI reporting. The downlink control information is limited to the second downlink control information and can be selected arbitrarily. Therefore, it is the second DCI.

[0186] 1. Network devices use RRC signaling to terminal devices via CSI-RS or It sends configuration information for the CSI report.

[0187] For a detailed explanation of this step, please refer to Step 1 in Figure 3. I will not explain it again.

[0188] 2. The network device uses the first MAC-CE message to deliver CSI-RS. Therefore, the terminal device is notified, and based on the configuration of the first MAC-CE message, the CSI-RS resource We will distribute the S.

[0189] For a detailed explanation of this step, please refer to Step 2 in Figure 3. I will not explain it again.

[0190] 3. The network device uses the first downlink control information to perform long-term semi-persistent CS Trigger the terminal device to perform both I reporting and short-term semi-permanent CSI reporting.

[0191] The network device is sending first downlink control information to the terminal device. In between, terminal devices perform both long-term semi-persistent CSI reporting and short-term semi-persistent CSI reporting. Please note that this will trigger the event.

[0192] Figure 7 shows that the time domain offset between long-term semi-permanent CSI reports and short-term semi-permanent CSI reports is different. Yes. Specifically, the reporting date for the first long-term semi-permanent CSI report is the same as the reporting date for the first short-term semi-permanent CSI report. This is earlier than the reporting date of the follow-up CSI report.

[0193] As an optional choice, the time domain offset for long-term semi-permanent CSI reporting is short-term semi-permanent. The time domain offset for the CSI report is insufficient.

[0194] 4. The terminal device will perform long-term, semi-permanent CSI reporting based on the CSI measurement results.

[0195] 5. The terminal device will perform short-term, semi-permanent CSI reporting based on the CSI measurement results.

[0196] As shown in Figure 7, terminal devices perform long-term semi-permanent CSI reporting based on measurement results. Short-term and semi-permanent CSI reports will be performed separately.

[0197] As an optional choice, the reporting cycle for long-term semi-permanent CSI reports is the same as that for short-term semi-permanent CSI reports. It is longer than the reporting cycle.

[0198] In step 3, the network device uses the first downlink control information , trigger terminal devices to perform long-term semi-persistent CSI reporting and short-term aperiodic CSI reporting. In this step, the terminal device will report the measurement results and the long-term semi-permanent CSI report. Based on the period, long-term semi-permanent CSI reports are periodically performed, and short-term aperiodic CSI reports are performed step by step. It is reported only once when triggered in step 3, and is not reported periodically in this step. Please understand this.

[0199] Please understand that Figure 7 provides N combinations of CSI reports. In other combinations... Adaptation reporting can also be performed by referring to this process. This is an implementation of the present application. Not limited by form.

[0200] 6. The network device sends second downlink control information to the terminal device. Turn off both long-term semi-permanent CSI reporting and short-term semi-permanent CSI reporting.

[0201] 7. The network device turns off CSI-RS distribution using the second MAC-CE message. do.

[0202] See Table 1. As long as the N types of CSI reports can match the types of CSI-RS deliveries, Therefore, the CSI-RS distribution in this step does not need to be semi-permanent. This is the practical application of this application. Not limited by the form of application.

[0203] Below, we will explain how downlink control information triggers N CSI reports, or how This explains in detail how the Unlink control information instructs the reporting configuration of N CSI reports. .

[0204] In some embodiments, the network device contains N downlink control information. Set the instruction information. The N instruction information corresponds one-to-one with the N trigger states in the trigger state list. Correspondingly, one trigger state corresponds to one CSI reporting configuration information.

[0205] As an option, N instruction information can be selected to match the N trigger states in the trigger state list. A one-to-one correspondence means that N instruction pieces correspond to N trigger states in a single trigger state list. It is acceptable for there to be a one-to-one correspondence.

[0206] As an option, N instruction information can be selected to match the N trigger states in the trigger state list. A one-to-one correspondence means that N instruction information corresponds to N trigger states in N trigger state lists. A one-to-one correspondence is also acceptable.

[0207] Specifically, N instruction information corresponds to N trigger state lists, and N instruction information Each instruction in the report corresponds to one trigger state in the corresponding trigger state list.

[0208] The trigger state list may be the aforementioned semiPersistentOnPUSCHTriggerStateList, Alternatively, it could be the aforementioned aperiodicTriggerStateList, or a trigger that is reset. Please note that a state list (TriggerStateList) is also acceptable.

[0209] The trigger state may be the aforementioned TriggerState, or the trigger state that is reset. Please note that this is acceptable.

[0210] This embodiment of the present application uses a solution that involves minimal modifications to an existing protocol. This will be explained using an example. However, this is not limited to this embodiment of the present application. .

[0211] As an arbitrary choice, each of the N instruction pieces corresponds to one CSI request instruction field. It may include "do".

[0212] The CSI request instruction field may be the same as the setting of the CSI request field described above. Alternatively, please note that it may be an instruction field that is reset. This embodiment of the application is not limited to this.

[0213] As an arbitrary choice, each of the N instruction pieces is a time-domain offset instruction piece. It also includes field.

[0214] The time domain offset assignment field is the aforementioned Time domain resource assignment. The field settings may be the same as, or the time domain offset assignment field may be It should be noted that this may also be an instruction field that is reset. This embodiment is not limited to this.

[0215] As an optional choice, each of the N instruction pieces will have a report content instruction field. It also includes.

[0216] Specifically, the Report Content Instructions field indicates the content of the CSI report, or The report content instruction field indicates whether the CSI report is long-term or short-term. For the meaning of "period," please refer to the explanation above, and we will not explain it in detail again here.

[0217] The report content instruction field may be optionally included in the trigger state. .

[0218] In the following, with reference to Figure 8, and Figures 9A and 9B, N instruction information forms N CSI report structures. Explain how to direct the generated information or how to trigger N CSI reports. ru.

[0219] We will use an example where N is equal to 2 to illustrate this point.

[0220] It should be noted that when N is greater than 2, the explanation can be made by referring to the step where N is equal to 2. In this embodiment of the present application, further details will not be described.

[0221] Figure 8 shows a configuration of long-term semi-permanent CSI reporting and short-term semi-permanent CSI reporting according to one embodiment of this application. This is a schematic diagram illustrating one example of the process.

[0222] Figures 9A and 9B show long-term semi-permanent CSI reporting and short-term aperiodic CSI reporting according to one embodiment of the present application. This is a schematic diagram illustrating an example of the process that constitutes the advertisement.

[0223] As shown in Figure 8, and in Figures 9A and 9B, specifically, each instruction is The process of determining the reporting structure of the CSI report using the information is explained in the same way as in Figures 3, 4, and 5. It seems so.

[0224] Specifically, the trigger state TriggerState in the trigger state list indicates each instruction It is associated with the codepoint configuration of the CSI Request field in the information. It can be selected arbitrarily. The trigger state list may be semiPersistentOnPUSCHTriggerStateList. ggerState is associated with one CSI-ReportConfig and is a Time domain resource assignment. In collaboration with nt, we have developed configuration information for semi-persistent CSI reporting, specifically ReportSlotConfig, ReportS Determine the lotOffset and CSI-RS ResourceConfig.

[0225] Alternatively, the trigger state TriggerState in the trigger state list is within the respective instruction information. It is associated with the codepoint configuration of the CSI Request field. Optionally, The trigger state list may be aperiodicOnPUSCHTriggerStateList. TriggerState is, Associated with one CSI-ReportConfig, Time domain resource assignment field In cooperation with the ResourceSet within the TriggerState associated with each CSI Request, aperiodic CS I. Determine the configuration information of the report, specifically ReportSlotOffset and CSI-RS-ResourceSet. do.

[0226] As an optional choice, you can select from within each instruction information, or corresponding to each instruction information. The TriggerState further includes a field indicating the content of the report.

[0227] Please understand that the field indicating the content of the report may be a CSI-TypeIndicate.

[0228] The optional fields for the report content instruction are CSI-Request and Time domain. The `n` resource assignment field may be irrelevant.

[0229] As an optional choice, the report content instruction field can instead be "Time domain resource". This may be included in the ce assignment information, and may be newly included in the Time domain resource assignment information. This is an additional bit.

[0230] The steps described above are for determining the CSI report configuration information corresponding to each of the N instruction pieces. It repeats.

[0231] In some embodiments, the network device contains one downlink control information Set the instruction information. One instruction information corresponds to one trigger state set in the trigger state list. Corresponding. A trigger state set contains N trigger states, or a trigger state set contains N Includes a series of trigger states.

[0232] One trigger state corresponds to one CSI report configuration information.

[0233] The trigger state list may be the aforementioned semiPersistentOnPUSCHTriggerStateList, Alternatively, it could be the aforementioned aperiodicTriggerStateList, or a trigger that is reset. Note that it can also be a state list, TriggerStateList. The trigger state list is, It includes multiple trigger state sets, each trigger state set containing N trigger states.

[0234] The trigger state set may be a TriggerStatePair, and This can be a different name that is reset.

[0235] The fact that N trigger states can be considered to be in cascaded order means that the trigger state set is virtual Yes, and it should be noted that this actually consists of N consecutive trigger states. Trigger states This may be the aforementioned TriggerState, or it may be a trigger state that is reset. .

[0236] This embodiment of the present application uses a solution that involves minimal modifications to an existing protocol. This will be explained using an example. However, this is not limited to this embodiment of the present application. .

[0237] Optionally, one instruction information may include a CSI request instruction field.

[0238] The CSI request instruction field may be the same as the setting of the CSI request field described above. Alternatively, please note that it may be an instruction field that is reset. This embodiment of the application is not limited to this.

[0239] As an optional choice, one instruction information consists of N time-domain offset instruction fields. It may further include the following.

[0240] N time-domain offset instruction fields correspond one-to-one with N CSI reports, and N CS Please note that the time domain offset for each report should be indicated.

[0241] Specifically, N time-domain offset instruction fields correspond to N ReportSlotOffs Specify the values ​​in etLists or another time-domain offset list to be reset, respectively. .

[0242] As an optional choice, N time-domain offset indicator fields are one indicator information It may be included in the trigger state set associated with it.

[0243] As an optional choice, each of the N trigger states associated with a single instruction is: The time-domain offset indicator field may include a time-domain offset indicator field, and the time-domain offset indicator field is , indicates the time-domain offset of the CSI report corresponding to the time-domain offset instruction field. ru.

[0244] As an optional choice, the time of the CSI report that has the minimum time domain among the N CSI reports. Only the domain offset needs to be configured; other CSIs are sequential time-domain offsets. Based on this, the slots are sequentially shifted to the rear of the x slot.

[0245] As an optional choice, the time-domain offset corresponding to N CSI reports is the default. This may be the case, and does not need to be indicated by a time-domain offset indication field. Optional One of the options is that one instruction information can be N-1 relative time-domain offset instruction fields. It may include a field. The relative time domain offset indicator field is one CSI report Specify the time domain offset for N-1 CSI reports relative to the notification. The domain offset is indicated by a single time-domain offset indicator field. In other words, Then, one instruction piece indicates only the time domain offset of one CSI report, and not another CSI report. The time-domain offset of a report is a relative value to the time-domain offset of a single CSI report.

[0246] As an example, not an exhaustive one, if downlink control information instructs two CSI reports, specifically... In general, when instructing one long-term CSI report and one short-term CSI report, the long-term CSI report is the short-term CSI report. The report may be set to be earlier, and the relative time domain offset instruction field is set. Furthermore, the relative time domain offset indicator field may be 2 bits. In addition, relative time An inter-region offset instruction list is set, and this list may be included in the CSI reporting configuration. The elements within the string may be {X0, X1, X2, X3}. Relative time domain offset indication field. If the bit value of is 11, the value X3 in the instruction list is the time between the short-term CSI report and the long-term CSI report. The fact that the interdomain offset difference is X3 can be rephrased as the time domain offset of the short-term CSI report. This means that X3 is greater than the time domain offset of the long-term CSI report.
