Description

Channel state information reporting method, configuration method and device Technical Field

[0001] The present application relates to the field of communications. Background Art

[0002] 5G NR supports Channel State Information (CSI) reporting. For example, a CSI report may include at least one of a CSI-RS Resource Indicator (CRI), an SSB Resource Indicator (SSBRI), L1-RSRP, and L1-SINR, that is, a beam-related report. The terminal device sends a beam report to the network device, and the network device can perform beam management based on it, for example, indicating a better beam for the terminal device. When the terminal device sends the CSI report is determined by the network device. The network device can configure periodic CSI reporting so that the terminal device sends CSI reports periodically; the network device can configure semi-persistent CSI reporting. After the semi-persistent CSI reporting is activated by the network device, the terminal device sends the CSI report periodically; the network device can configure aperiodic CSI reporting. After the aperiodic CSI reporting is triggered by the network device, the terminal device sends a CSI report once. The CSI report includes measurement results for the serving cell. Rel-17 adds support for ICBM (Inter Cell Beam Management). In ICBM, the CSI report can include measurement results for non-serving cells, so that the network equipment can instruct the terminal device to use the beam of the non-serving cell, but the terminal device does not switch to the non-serving cell.

[0003] Rel-18 adds support for LTM CSI reports. Rel-18 supports LTM (L1 / L2 Triggered Mobility). In LTM, terminal devices can send LTM CSI reports. Rel-18's LTM CSI reports include SSBRI and L1-RSRP. Unlike the traditional CSI reports mentioned above, LTM CSI reports include measurement results for candidate cells. The network equipment can determine the beam to be used in the candidate cell for the terminal device based on this, and indicate the beam to the terminal device before switching to the candidate cell, so that the terminal device can quickly apply the appropriate beam for data transmission after switching. In other words, in LTM, the terminal device switches to the candidate cell and uses the beam of the candidate cell after switching. Similarly, the terminal device can send LTM CSI reports in a periodic, semi-continuous, or non-periodic manner.

[0004] It should be noted that the above introduction to the technical background is merely for convenience, to provide a clear and complete description of the technical solutions of this application and to facilitate understanding by those skilled in the art. It should not be assumed that the above technical solutions are well known to those skilled in the art simply because they are described in the background technology section of this application.

[0005] Summary of the Invention

[0006] In the upcoming Rel-19, further enhancements to CSI reporting and LTM CSI reporting will be introduced, namely, support for event-triggered CSI reporting and event-triggered LTM CSI reporting. Event-triggered CSI reporting and event-triggered LTM CSI reporting correspond to traditional CSI reporting and LTM CSI reporting, respectively. Unlike the traditional reporting mentioned above, for event-triggered reporting, when the terminal device sends the report is determined by the terminal device, that is, through event triggering. In other words, the terminal device only sends the report when necessary, so that the report can be sent more promptly. In addition, since unnecessary reports are avoided, the reporting overhead can also be reduced. How to support event-triggered CSI reporting and event-triggered LTM CSI reporting is a problem that needs to be solved. At present, 3GPP has just approved the establishment of Rel-19 and has not yet started to discuss the relevant technical details of event-triggered CSI reporting and event-triggered LTM CSI reporting.

[0007] The inventors have discovered that a terminal device may be configured with one or more network device-scheduled reports (“CSI reports” and “LTM CSI reports” are collectively referred to as “network device-scheduled reports”). For example, for network device-scheduled reports, different reports may be associated with different CSI measurement resources, and / or have different report types (periodic, non-periodic, semi-continuous). Existing standards define the priorities of network device-scheduled reports, so that the priority relationship between network device-scheduled reports can be determined. Similarly, a terminal device may be configured with one or more event-triggered reports (“event-triggered CSI reports” and “event-triggered LTM CSI reports” are collectively referred to as “event-triggered reports”). For example, different event-triggered reports are associated with different CSI measurement resources, and / or are associated with different events, and / or are associated with different report quantities.

[0008] Determining the priority of event-triggered reports, including determining the priority relationship between event-triggered reports and reports scheduled by network devices, and determining the priority relationship between event-triggered reports themselves, are all issues that need to be addressed. For example, if a terminal device needs to select between an event-triggered report and a report scheduled by a network device ("reports scheduled by network devices" and "event-triggered reports" are collectively referred to as "reports") to send, the question of which report is prioritized is a question that needs to be addressed. Otherwise, the terminal device and the network device may have inconsistent understandings of which report to send, resulting in the failure of the entire report transmission.

[0009] In order to solve one or more of the above problems, embodiments of the present application provide a channel state information reporting method, configuration method, and apparatus.

[0060] The following describes various implementations of the present application in conjunction with the accompanying drawings. These implementations are merely illustrative and are not intended to limit the present application.

[0061] Embodiments of the first aspect

[0062] An embodiment of the present application provides a channel state information reporting method, which is applied to a terminal device, such as the terminal device 102 in Figure 1.

[0063] In the embodiments of the present application, “CSI report” and “LTM CSI report” are collectively referred to as “report scheduled by network device”, “event-triggered CSI report” and “event-triggered LTM CSI report” are collectively referred to as “event-triggered report”, and “network device-scheduled report” and “event-triggered report” are collectively referred to as “report”.

[0064] For example, the report includes at least one of: a CSI report, an LTM CSI report, an event-triggered CSI report, and an event-triggered LTM CSI report.

[0065] For example, the event-triggered report includes at least one of an event-triggered CSI report and an event-triggered LTM CSI report; and the report scheduled by the network device includes at least one of a CSI report and an LTM CSI report.

[0066] In the embodiment of the present application, "event-triggered report" is also referred to as "event-triggered report".

[0067] In the embodiment of the present application, “event triggered” may be replaced by “UE initiated” or “event driven”.

[0068] FIG2 is a schematic diagram of a channel state information reporting method according to an embodiment of the present application. As shown in FIG2 , the method includes:

[0069] 201: The terminal device receives configuration information; and

[0070] 202: The terminal device sends at least one of an event-triggered CSI report, a CSI report, an event-triggered LTM CSI report, and an LTM CSI report, where the priority of the event-triggered CSI report is higher than the priority of the CSI report.

[0071] In operation 201, for example, a terminal device receives configuration information from a network device, where the configuration information is configuration information about CSI reporting.

[0072] For example, the configuration information includes at least one of the following configuration information:

[0073] Event triggers CSI resource configuration;

[0074] Event-triggered CSI reporting configuration;

[0075] Event triggers LTM CSI resource configuration;

[0076] Event-triggered LTM CSI report configuration;

[0077] CSI resource allocation;

[0078] CSI report configuration;

[0079] LTM CSI resource configuration;

[0080] LTM CSI reporting configuration.

[0081] In operation 202, the terminal device sends at least one of an event-triggered CSI report, a CSI report, an event-triggered LTM CSI report, and an LTM CSI report. For example, the terminal device sends at least one of an event-triggered CSI report, a CSI report, an event-triggered LTM CSI report, and an LTM CSI report according to the above configuration information.

[0082] When sending at least one of an event-triggered CSI report, a CSI report, an event-triggered LTM CSI report, and an LTM CSI report, the sending is performed based on a priority of the event-triggered report. For example, the sending is performed based on a priority relationship between the event-triggered report and a report scheduled by the network device and / or a priority relationship between the event-triggered reports.

[0083] In some embodiments, "high priority" means "given priority", for example, report A has a higher priority than report B, which means: between report A and report B, report A is given priority in being sent.

[0084] In some embodiments, event-triggered reporting has a higher priority than network device scheduling.

[0085] For example, the priority of an event-triggered CSI report is higher than the priority of a CSI report. Both CSI reports and event-triggered CSI reports are used for intra-cell and inter-cell beam management. A terminal device can be configured with a CSI report and an event-triggered CSI report at the same time. A CSI report is a report scheduled by a network device, and an event-triggered CSI report is a report initiated by a terminal device. Since the terminal device can know the beam change before the network device, the report initiated by the terminal device can notify the beam change more timely and accurately. Therefore, the event-triggered CSI report takes precedence over the CSI report. For example, when the terminal device needs to choose one to send between an event-triggered CSI report and a CSI report, the terminal device sends an event-triggered CSI report instead of a CSI report, that is, the event-triggered CSI report is sent first.

[0086] For example, the priority of an event-triggered LTM CSI report is higher than the priority of an LTM CSI report. Both LTM CSI reports and event-triggered LTM CSI reports are used for cell handover. A terminal device can be configured with both LTM CSI reports and event-triggered LTM CSI reports. Because the terminal device can know about inter-cell beam changes before the network device, reports initiated by the terminal device can notify inter-cell beam changes more promptly and accurately. Therefore, event-triggered LTM CSI reports take precedence over LTM CSI reports.

[0087] In some embodiments, the priority of LTM CSI reporting is higher than the priority of event-triggered CSI reporting.

[0088] LTM CSI reports are used for cell switching. Event-triggered CSI reports are used for intra-cell and inter-cell beam association, but are not used for cell switching purposes. LTM CSI reports are configurable. If cell switching is not required, the network device does not need to configure LTM CSI reports for the terminal device. The reason why the network device configures LTM CSI reports for the terminal device is that it believes that the terminal device is likely to need to perform cell switching. Once the network device configures the terminal device to send LTM CSI reports, it means that cell switching is the current main purpose. Therefore, LTM CSI reports used for cell switching should take precedence over event-triggered CSI reports that are not used for cell switching. For example, when the terminal device needs to choose between an event-triggered CSI report and an LTM CSI report to send, the terminal device gives priority to sending the LTM CSI report.

[0089] In some embodiments, the priority corresponds to a priority value, and the smaller the priority value, the higher the priority.

[0090] For example, a report has a priority value, and a report with a smaller priority value takes precedence over a report with a larger priority value. The "report" here can be at least one of an event-triggered CSI report, a CSI report, an event-triggered LTM CSI report, and an LTM CSI report.

[0091] For example, a CSI report triggered by an event with a small priority value takes precedence over a CSI report triggered by an event with a large priority value, or a CSI report triggered by an event with a small priority value takes precedence over a CSI report triggered by a large priority value, or a CSI report triggered by an event with a small priority value takes precedence over a CSI report triggered by a large priority value, or a CSI report triggered by an event with a small priority value takes precedence over a CSI report triggered by an event with a large priority value.

[0092] However, in some embodiments, the larger the priority value, the higher the priority.

[0093] The following describes in detail how to determine the priority values ​​of different types of reports.

[0094] In some embodiments, the priority value of the event triggering the CSI report and the priority value of the CSI report are determined according to at least one of the first parameter, the second parameter, the third parameter, and the fourth parameter.

[0095] The first parameter is determined according to the report type, the second parameter is determined according to the report quantity, the third parameter is determined according to the cell index, and the fourth parameter is determined according to the report configuration number.

[0096] The report configuration number (ID) may also be referred to as the report configuration identification.

[0097] For example, the priority value of the event-triggered CSI report and the priority value of the CSI report are determined according to y, k, c, and s, where y is determined according to the report type, k is determined according to the report quantity, c is determined according to the cell index, and s is determined according to the report configuration number.

[0098] In some embodiments, the value of the first parameter of the event-triggered CSI report is different from the value of the first parameter of the CSI report.

[0099] For example, the y value of the event-triggered CSI report and the CSI report are different.

[0100] In some embodiments, the event-triggered CSI reporting configuration used to configure the event-triggered CSI reporting and the CSI reporting configuration used to configure the CSI reporting are numbered uniformly.

[0101] For example, the s configured by the event triggering CSI report is in the interval [0, M s -1] are numbered uniformly.

[0102] The following is a specific explanation using an example.

[0103] For example, the priority value of the event-triggered CSI report and the priority value of the CSI report are both determined according to formula (1). iCSI (y,k,c,s)=M k ·M c ·M s y+M c ·M s k+M s ·c+s (1)

[0104] Wherein, y represents the report type. For example, for event-triggered CSI reporting, y=0; for CSI reporting, y>0. CSI reporting includes aperiodic CSI reporting, semi-persistent CSI reporting, and periodic CSI reporting. More specifically, for aperiodic CSI reporting carried by the Physical Uplink Shared Channel (PUSCH), y=1; for semi-persistent CSI reporting carried by PUSCH, y=2; for semi-persistent CSI reporting carried by the Physical Uplink Control Channel (PUCCH), y=3; for periodic CSI reporting carried by PUCCH, y=4;

[0105] k represents the reported amount, M k -1 indicates the maximum value of k (0≤k≤Mk -1). For example, for a report carrying L1-RSRP or L1-SINR (Signal to Interference plus Noise Ratio), k=0, for a report not carrying L1-RSRP or L1-SINR, k=1, and M k =2. In the description of formula (1), the “report” mentioned can be an event-triggered CSI report or a CSI report. For example, for an event-triggered CSI report, k=0, for a CSI report, for a report carrying L1-RSRP or L1-SINR, k=0, for a report not carrying L1-RSRP or L1-SINR, k=1, and M k =2;

[0106] c represents the cell index, M c -1 indicates the maximum value of c (0≤c≤M c -1). For example, M c It is the parameter maxNrofSrevingCells configured by the higher layers, i.e. the maximum number of serving cells. For example, c means that the report includes the measurement results for cell c, i.e. the measurement resources associated with the report are in cell c. For example, c means the cell where the report is located, i.e. the report is sent on cell c;

[0107] s represents the report configuration number (report configuration ID), M s -1 indicates the maximum value of s (0≤s≤M s -1). For example, for event-triggered CSI reporting or CSI reporting, s is the parameter CSI-ReportConfigId configured by the higher layer, M s It is the parameter maxNrofCSI-ReportConfigurations configured by the higher layer, that is, the event-triggered CSI report configuration and the CSI report configuration are numbered uniformly. In other words, the report configuration number of the event-triggered CSI report or the CSI report is determined by CSI-ReportConfigId, where 0≤CSI-ReportConfigId≤maxNrofCSI-ReportConfigurations-1.

[0108] In some embodiments, the priority value of the event-triggered CSI report is determined according to at least one of a fifth parameter and a sixth parameter, wherein the fifth parameter is determined according to the cell index and the sixth parameter is determined according to the report configuration number;

[0109] The priority value of the CSI report is determined according to at least one of the seventh parameter, the eighth parameter, the ninth parameter, and the tenth parameter, wherein the seventh parameter is determined according to the report type, the eighth parameter is determined according to the report amount, the ninth parameter is determined according to the cell index, and the tenth parameter is determined according to the report configuration number.

[0110] For example, the priority value of the event-triggered CSI report is determined according to c0 and s0, where c0 is determined according to the event-triggered CSI report cell index, and s0 is determined according to the event-triggered CSI report configuration identifier; the priority value of the CSI report is determined according to y1, k1, c1, and s1, where y1 is determined according to the CSI report type, k1 is determined according to the CSI report amount, c1 is determined according to the CSI report cell index, and s1 is determined according to the CSI report configuration identifier.

[0111] In some embodiments, the event-triggered CSI reporting configuration used to configure the event-triggered CSI report and the CSI reporting configuration used to configure the CSI report are numbered independently.

[0112] For example, the event triggers CSI report configuration s0 in the interval Internal number, CSI report configuration s1 in the interval Internal number.

[0113] The following is a detailed description using another example.

[0114] For example, the priority value of the event-triggered CSI report and the priority between the event-triggered CSI reports are determined according to formula (2).

[0115] Wherein, s0 represents the event-triggered CSI report configuration identifier (event-triggered CSI report configuration ID), Indicates the maximum value of s0 For example, for event-triggered CSI reporting, s0 is the parameter EventTriggered-CSI-ReportConfigId configured in the higher layer. It is the parameter maxNrofeventTriggered-CSI-ReportConfigurations configured by the higher layer. According to the definition of s0, the event-triggered CSI report configuration and the CSI report configuration are numbered independently;

[0116] c0 represents the cell index, Indicates the maximum value of c For example, This is the parameter maxNrofSrevingCells configured by higher layers, which is the maximum number of serving cells. For example, c0 indicates that the report includes measurement results for cell c0, meaning that the measurement resources associated with the report are within cell c0. For example, c0 indicates the cell in which the report is located, meaning that the report is sent on cell c0.

[0117] For example, an event-triggered CSI report takes precedence over a CSI report, and the priority value of the CSI report and the priority between CSI reports are determined according to formula (3).

[0118] Where y1 represents the CSI report type. For example, for aperiodic CSI reporting carried by PUSCH, y1=0; for semi-persistent CSI reporting carried by PUSCH, y1=1; for semi-persistent CSI reporting carried by PUCCH, y1=2; for periodic CSI reporting carried by PUCCH, y1=3;

[0119] The definitions of k1, c1, and s1 are similar to those of k, c, and s, respectively, except that they are defined only for CSI reporting (only within the CSI reporting scope). In addition, according to the definition of s1, event-triggered CSI reporting configurations are numbered independently from CSI reporting configurations.

[0120] In some embodiments, the mapping order of the reports is determined according to the priority, or when the reporting code rate is higher than a threshold, a portion of the reports to be sent is determined according to the priority.

[0121] The report includes at least one of an event-triggered CSI report, a CSI report, an event-triggered LTM CSI report, and an LTM CSI report.

[0122] For example, the priority or priority value of a report is used to determine the mapping order of the report, or to omit a portion of the reports when the report code rate is higher than a threshold. For example, an uplink transmission can carry multiple reports. When multiple reports are multiplexed onto PUCCH or PUSCH for transmission, the multiple reports can be arranged in order of priority from high to low (i.e., the mapping order is determined by the priority), and the terminal device sends all reports. For example, when multiple reports are multiplexed onto PUCCH or PUSCH for transmission, the code rate of the report may be higher than a certain threshold, resulting in a failure in the transmission of the report. In this case, the terminal device can select a portion of the reports to send in order of priority from high to low, that is, ignore (not send) the remaining reports, thereby ensuring that the code rate of the report is less than or equal to the threshold, thereby ensuring the reliability of the transmission.

[0123] In some embodiments, when the event-triggered CSI report and the CSI report associated with the same group of CSI measurement resources need to be sent simultaneously, the event-triggered CSI report is sent and the CSI report is not sent, and / or, when the event-triggered LTM CSI report and the LTM CSI report associated with the same group of LTM CSI measurement resources need to be sent simultaneously, the event-triggered LTM CSI report is sent and the LTM CSI report is not sent.

[0124] For example, when an event-triggered CSI report and a CSI report associated with the same set of CSI measurement resources need to be sent simultaneously, the terminal device only sends the event-triggered CSI report and does not send the CSI report. Similarly, this can be extended to the case of sending event-triggered LTM CSI reports and LTM CSI reports.

[0125] For example, Figure 3 is a schematic diagram of an event-triggered CSI report and the association between the CSI report and the CSI resource configuration according to an embodiment of the present application. In addition, the following is an example of the association relationship between the report configuration and the resource configuration.

[0126] As shown in Figure 3 and the above example, an event-triggered CSI report (configured by EventTriggered-CSI-ReportConfig) and a CSI report (configured by CSI-ReportConfig) are associated with the same CSI resource configuration, which is configured by CSI-ResourceConfig. The CSI resource configuration ID (CSI-ResourceConfigId) is #n.

[0127] Figure 4 is a schematic diagram illustrating the relationship between resources used to transmit an event-triggered CSI report and a CSI report in an embodiment of the present application. As shown in Figure 4, the resources used to transmit the event-triggered CSI report and the CSI report overlap in the time domain and / or frequency domain. The CSI report in Figure 4 is a periodic CSI report carried by the PUCCH.

[0128] According to Figures 3 and 4 and the above examples, the terminal device needs to send a CSI report at the same time as the event-triggered CSI report, that is, send two reports. However, because both the event-triggered CSI report and the CSI report report measurement results for the same set of CSI resources (corresponding to the same CSI resource configuration), the information reported by the two reports is duplicated or redundant. Therefore, the terminal device can send only one report instead of two reports.

[0129] Figure 5 is a schematic diagram of a priority-based report transmission mechanism according to an embodiment of the present application. As shown in Figure 5 , considering that event-triggered CSI reports take precedence over CSI reports, the terminal device only transmits event-triggered CSI reports and does not transmit CSI reports.

[0130] In some embodiments, event-triggered CSI reports and / or event-triggered LTM CSI reports are sent via DCI scheduling.

[0131] For example, an event-triggered CSI report or an event-triggered LTM CSI report is sent via a DCI-scheduled PUSCH. For example, after an event occurs, the terminal device notifies the network device, which then schedules the terminal device to send a PUSCH via DCI. The event-triggered report is included in the PUSCH and sent. The term "event-triggered report" refers to an event-triggered CSI report or an event-triggered LTM CSI report, collectively referred to as "event-triggered report."

[0132] In some embodiments, event-triggered CSI reporting is carried by UCI or MAC-CE, and / or event-triggered LTM CSI reporting is carried by UCI or MAC-CE.

[0133] For example, the event-triggered report is carried by the UCI, and the UCI is multiplexed onto a PUSCH without UL-SCH for transmission.

[0134] For example, the event-triggered report is carried by the UCI, and the UCI is multiplexed onto the PUSCH with UL-SCH for transmission.

[0135] For example, the event triggering report is carried by MAC-CE, and MAC-CE is included in PUSCH and sent.

[0136] The following is a specific explanation using an example.

[0137] For example, the terminal device needs to send the following four types of reports at the same time:

[0138] The event triggers CSI report R1;

[0139] CSI report R2, where R2 and R1 are associated with the same set of CSI measurement resources;

[0140] CSI report R3, where R3 and R1 are associated with two different sets of CSI measurement resources;

[0141] LTM CSI Report R4;

[0142] Because R2 and R1 are associated with the same set of CSI measurement resources, the terminal device does not send R2. Regardless of whether the reported bit rate is above the threshold, the terminal device does not send R2. If the reported bit rate is above the threshold, the terminal device selects the report to send from R1, R3, and R4 in descending order of priority until the reported bit rate reaches the maximum while meeting the condition of being less than or equal to the threshold. The priority of R1, R3, and R4 is in the following order: R4 > R1 > R3.

[0143] In some embodiments, the CSI measurement resources associated with the event-triggered CSI report are different from the CSI measurement resources associated with the CSI report, and / or the CSI measurement resources associated with the event-triggered LTM CSI report are different from the CSI measurement resources associated with the LTM CSI report.

[0144] For example, the terminal device does not expect to be configured with event-triggered CSI reports and CSI reports associated with the same CSI resource configuration ID.

[0145] For example, the terminal device does not expect to be configured with event-triggered LTM CSI reports and LTM CSI reports associated with the same CSI resource configuration ID.

[0146] In this way, the situation where the relationships shown in FIG. 3 and FIG. 4 occur simultaneously can be avoided, and thus there is no need to define terminal device behavior for this situation.

[0147] In some embodiments, event-triggered reports do not always take precedence over reports scheduled by the network device. Instead, they may take precedence over reports scheduled by the network device when certain conditions are met. For example, when the reporting volume is the same, event-triggered CSI reports may take precedence over CSI reports, and / or, when the reporting volume is the same, event-triggered LTM CSI reports may take precedence over LTM CSI reports.

[0148] For example, event-triggered CSI reporting does not always take precedence over CSI reporting. It only takes precedence over CSI reporting when the reporting volume of event-triggered CSI reporting and CSI reporting is the same. Similarly, this can be extended to determining the priority of event-triggered LTM CSI reporting and LTM CSI reporting.

[0149] FIG6 is a schematic diagram of another embodiment of the channel state information reporting method of the present application. As shown in FIG6, the method includes:

[0150] 601: The terminal device receives configuration information; and

[0151] 602: The terminal device sends at least one of an event-triggered CSI report, a CSI report, an event-triggered LTM CSI report, and an LTM CSI report.

[0152] In which, when the first preset condition is met, the priority of the event-triggered CSI report is higher than the priority of the CSI report, and / or, when the second preset condition is met, the priority of the event-triggered LTM CSI report is higher than the priority of the LTM CSI report.

[0153] In some embodiments, the priority of the LTM CSI report is higher than the priority of the event-triggered CSI report.

[0154] In some embodiments, the first preset condition is that the event-triggered CSI report is the same as the reporting amount of the CSI report, and / or the second preset condition is that the event-triggered LTM CSI report is the same as the reporting amount of the LTM CSI report.

[0155] As can be seen from the above embodiment, the priority of an event-triggered CSI report is higher than the priority of a CSI report. The priority of an LTM CSI report is higher than the priority of an event-triggered CSI report. Priority is determined based on a priority value. The priority value of an event-triggered CSI report and the priority value of a CSI report can be calculated jointly or independently. This avoids ambiguity in determining the priority level of a report, thereby preventing report transmission failures caused by this.
