Description

Data sending and receiving method and device Technical Field

[0001] The embodiments of the present application relate to the field of communication technologies. Background Art

[0002] During the standardization process for Release 18 (Rel-18), the 3GPP standardization organization conducted research on Layer 1 / Layer 2 Triggered Mobility (LTM). The goal of Rel-18 LTM is to reduce handover interruptions by performing cell handovers based on Layer 1 / Layer 2 signaling (Layer 1 / Layer 2 triggered), thereby enabling faster handovers from the serving cell (source cell) to the target cell.

[0003] It should be noted that the above introduction to the technical background is only for the convenience of providing a clear and complete description of the technical solutions of this application and for the convenience of understanding by those skilled in the art. It cannot be considered that the above technical solutions are well known to those skilled in the art simply because these solutions are explained in the background technology part of this application.

[0004] Summary of the Invention

[0005] Rel-18 studies Layer 1 / Layer 2 Triggered Mobility (LTM). For Rel-18 LTM, the goal is to reduce handover interruption through cell switching based on Layer 1 / Layer 2 signaling (Layer 1 / Layer 2 triggered), so as to switch from the serving cell (source cell) to the target cell faster. The target cell is the cell after switching, which can be a serving cell or a non-serving cell. Handover interruption refers to the time from the terminal device receiving the cell switch command to the first successful completion of uplink or downlink transmission between the terminal device and the target cell. Compared with the traditional cell switching based on Layer 3 signaling, the cell switching based on Layer 1 / Layer 2 signaling can further reduce handover interruption. To achieve cell switching based on layer 1 / layer 2, the terminal device measures multiple candidate cells, for example, measures the layer 1-reference signal receiving power (L1-RSRP) of the system synchronization block (SSB); and reports the measurement results to the source cell, for example, sends a channel state information report (CSI report). The source cell indicates to the terminal device which candidate cell to switch to through a cell switching command (the indicated candidate cell becomes the target cell); and indicates the beam used for uplink and downlink transmission in the target cell after switching, for example, the transmission configuration indication state (TCI state). The source cell, candidate cell, and target cell in Rel-18 LTM all support the Rel-17 unified TCI state (unified TCI). Therefore, the aforementioned indicated TCI state is the unified TCI state.

[0006] In addition, in Rel-18 LTM, the candidate cell configuration (candidate cell configuration), measurement configuration and reporting configuration (CSI report configuration) are provided by the source cell to the terminal device before the cell switching command. The candidate cell configuration includes the Radio Resource Control (RRC) configuration applied by the terminal device after switching to the target cell, that is, the RRC configuration of the target cell. The terminal device can immediately apply the RRC configuration of the target cell after the cell switching, thereby quickly completing the successful uplink or downlink transmission with the target cell; the measurement configuration mainly includes the configuration of the measurement reference signal (such as SSB); the CSI report configuration configures the information required for reporting. For a specific RRC signaling structure, for example, the CSI report configuration is included in the serving cell configuration, and the measurement configuration is located outside the serving cell configuration and the candidate cell configuration.

[0007] The inventors discovered that: in order to support Rel-18 LTM, a CSI report for cell switching purposes was introduced in Rel-18 LTM, which is referred to as LTM CSI report. In contrast to the LTM CSI report is the traditional CSI report, wherein, for the traditional CSI report, one CSI report is associated with one priority value, and different CSI reports are associated with different priority values. When the terminal device needs to select a part of CSI reports to be sent from multiple CSI reports according to a priority rule, the terminal device selects a part of CSI reports with higher priority. The configuration of the CSI report is provided to the terminal device, for example, the LTM CSI report and the traditional CSI report are configured independently.

[0008] Since Rel-18 LTM newly introduces LTM CSI reports, how to determine the priority of LTM CSI reports (including how to determine the priority value of LTM CSI reports and how to determine the priority between LTM CSI reports and traditional CSI reports) is a problem that needs to be solved.

[0009] To address at least one of the above problems, embodiments of the present application provide a method and apparatus for sending and receiving data.

[0020] a determining unit, configured to determine a priority of the first channel state information report and / or the second channel state information report;

[0021] A first sending unit is configured to send the first channel state information report and / or the second channel state information report according to a determined priority.

[0022] According to another aspect of an embodiment of the present application, a data receiving device is provided, configured in a network device, the data receiving device comprising:

[0023] a second configuration unit configured to configure a first channel state information report and / or a second channel state information report to a terminal device, wherein the first channel state information report is related to layer 1 / layer 2 triggered mobility, and the second channel state information report is not related to layer 1 / layer 2 triggered mobility; wherein the terminal device determines a priority of the first channel state information report and / or the second channel state information report;

[0024] A second receiving unit receives the first channel state information report and / or the second channel state information report sent by the terminal device according to the determined priority.

Unless otherwise specified herein, "device" can refer to either network equipment or terminal equipment.

[0058] The following describes the scenarios of the embodiments of the present application through examples, but the present application is not limited thereto.

[0059] Figure 1 is a schematic diagram of a communication system according to an embodiment of the present application, which schematically illustrates a situation taking a terminal device and a network device as an example. As shown in Figure 1 , a communication system 100 may include a first network device 101, a second network device 102, and a terminal device 103. For simplicity, Figure 1 only illustrates two network devices and one terminal device as an example, but the embodiment of the present application is not limited to this.

[0060] For example, the first network device 101 is the serving cell (source cell) of the terminal device 103 , and the second network device 102 is the cell after switching (target cell) of the terminal device 103 .

[0061] For traditional CSI reports, each CSI report is associated with a priority value. Different CSI reports are associated with different priority values, with smaller priority values ​​indicating higher priority. When a terminal device needs to select a subset of CSI reports to send based on a priority rule, the terminal device selects CSI reports in ascending order of priority values, i.e., it selects the CSI reports with higher priorities.

[0062] For example, for traditional CSI reports, a CSI report has a priority, which is used in the priority rules. Based on the priority rules, the terminal device preferentially sends CSI reports with higher priorities, or ignores (omit) or discards CSI reports with lower priorities. A CSI report is associated with a priority value, and the priority can be determined based on the priority value. The smaller the priority value, the higher the priority. A CSI report includes CSI part 1, or includes CSI part 1 and CSI part 2.

[0063] Figure 2 is a schematic diagram of a conventional CSI report according to an embodiment of the present application. For example, a terminal device needs to send multiple CSI reports simultaneously, and the priority of the CSI reports increases from bottom to top. If a portion of the CSI reports needs to be sent, the terminal device selects the CSI reports with the highest priority to send.

[0064] For example, for the same CSI report, the priorities of CSI part 1, wideband CSI part 2, even subband CSI part 2, and odd subband CSI part 2 decrease in descending order. For example, as shown in FIG2 , for CSI report #1, CSI part 1 has a higher priority than wideband CSI part 2, higher than even subband CSI part 2, and higher than odd subband CSI part 2. For different CSI reports, a CSI report with a smaller priority value has a higher priority. For example, as shown in FIG2 , CSI part 1 of CSI report #1 has a smaller priority value than CSI part 1 of CSI report #2, so CSI report #1 has a higher priority. In other words, for CSI part 1 of different CSI reports, the priority is determined according to the priority value; the smaller the priority value, the higher the priority. The CSI mapping order (i.e., the order in which each part of the CSI is arranged in the terminal device report) is also obtained according to the order of high to low priority as shown in FIG2 .

[0065] The inventors discovered that since Rel-18 LTM introduced LTM CSI reporting and LTM CSI reporting and traditional CSI reporting are configured independently, determining the priority of LTM CSI reporting (including determining the priority value of LTM CSI reporting and determining the priority difference between LTM CSI reporting and traditional CSI reporting) is a problem that needs to be solved.

[0066] For example, if the priority value of the LTM CSI report is calculated using the method for calculating the priority value of the traditional CSI report, ambiguity will arise when determining the priority size. For traditional CSI reports, the CSI report configuration identifiers of different CSI reports are different, and the priority values ​​calculated based on different CSI report configuration identifiers are also different. However, the LTM CSI report and the traditional CSI report are configured independently, and the CSI report configuration identifiers of the LTM CSI report and the traditional CSI report can both start from zero. Therefore, it is possible that the LTM CSI report and the traditional CSI report have the same CSI report configuration identifier, and the priority value calculated based on the same CSI report configuration identifier is also the same. If the terminal device needs to send an LTM CSI report and a traditional CSI report at the same time, and needs to choose one of the LTM CSI report and the traditional CSI report with the same priority value to send, there is ambiguity in the question of which CSI report to select, because at this time the priority size cannot be determined based on the priority value. If the terminal device and the network device have inconsistent understandings on which CSI report to select, the transmission of the entire CSI report (including other uplink control information (UCI) multiplexed therewith) may fail.

[0067] To address at least one of the above problems, embodiments of the present application provide a method and apparatus for sending and receiving data.

[0068] Embodiments of the first aspect

[0069] An embodiment of the present application provides a data sending method, which is applied on a terminal device side.

[0070] FIG3 is a schematic diagram of a data transmission method according to an embodiment of the present application. As shown in FIG3 , the method includes:

[0071] 301, a terminal device is configured with a first CSI report and / or a second CSI report, wherein the first CSI report is related to Layer 1 / Layer 2 Triggered Mobility (L1 / L2 Triggered Mobility, LTM), and the second CSI report is not related to Layer 1 / Layer 2 Triggered Mobility (LTM);

[0072] 302. The terminal device determines a priority of the first CSI report and / or the second CSI report;

[0073] 303. The terminal device sends the first CSI report and / or the second CSI report according to the determined priority.

[0074] The terminal device is configured with a first CSI report and / or a second CSI report, determines a priority for the first CSI report and / or the second CSI report, and transmits the first CSI report and / or the second CSI report based on the determined priority. This avoids ambiguity in determining the priority of the CSI report, thereby avoiding CSI report transmission failures caused by this.

[0075] It is worth noting that FIG3 above is merely a schematic illustration of an embodiment of the present application, using a terminal device as an example, but the present application is not limited thereto. For example, the execution order of the various operations may be appropriately adjusted, other operations may be added or some operations may be reduced, and the objects of the aforementioned operations may be adjusted. Those skilled in the art may make appropriate modifications based on the above description, and are not limited to the description of FIG3 above.

[0076] In some embodiments, terms such as "transmission configuration indication state (TCI state)" and "beam" can be used interchangeably; "cell" can be equivalently replaced by "carrier" or "component carrier"; "TCI state pool" can be equivalently replaced by "TCI state set" or "TCI state list"; the above is only an exemplary description, and the embodiments of the present application are not limited to this.

[0077] In some embodiments, before receiving a cell switch command, the terminal device is configured with one or more candidate cells and provided with configuration information related to the candidate cells; the cell switch command then instructs the terminal device to switch to one or more of the candidate cells (i.e., target cells).

[0078] In some embodiments, the cell to which the terminal device belongs before cell switching is called a "serving cell" or a "source cell," and the cell to which the terminal device belongs after cell switching is called a target cell; for example, the "serving cell" sends a switching command (cell switch command) to the terminal device, for example, the switching command (cell switch command) is carried by a media access control layer control element (MAC CE). Thus, the cell switching is indicated by layer 1 or layer 2 signaling, so that the terminal device can quickly switch cells. For example, the MAC CE format corresponding to the switching command (cell switch command) can refer to the existing technology, and this application does not limit this.

[0079] In some embodiments, the first CSI report is related to Layer 1 / Layer 2 Triggered Mobility (LTM), and the second CSI report is not related to Layer 1 / Layer 2 Triggered Mobility (LTM). For example, the first CSI report is a CSI report related to LTM, such as a CSI report performed for LTM purposes (cell handover purposes), and the first CSI report may also be referred to as an LTM CSI report; the second CSI report is a CSI report unrelated to LTM, that is, a CSI report performed for non-LTM purposes, and the second CSI report may also be referred to as a legacy CSI report.

[0080] The following describes how the terminal device is configured with the first CSI report and / or the second CSI report:

[0081] In some embodiments, the method further includes: 304, the terminal device receives configuration information, wherein the configuration information configures the first CSI report (CSI report) and / or the second CSI report (CSI report). In some embodiments, the configuration information is carried by an RRC message.

[0082] For example, the "serving cell" of the terminal device sends the configuration information through an information element (IE) in an RRC message, and the terminal device is configured with the first CSI report and / or the second CSI report according to the configuration information.

[0083] For example, the configuration information is carried through an IE in an RRC message. For example, the "serving cell" can configure the first CSI report and the second CSI report through the same IE in the configuration information, or the "serving cell" can configure the first CSI report and the second CSI report through different IEs in the configuration information. This application does not limit this.

[0084] The following Table 1 illustrates an example of configuring the first CSI report and the second CSI report through different IEs in the configuration information.

[0085] Table 1

[0086] For example, Table 1 is the specific IE content of the configuration information of an embodiment of the present application; as shown in Table 1, the configuration information includes at least a first CSI report configuration (LTM-CSI-ReportConfig) and a second CSI report configuration (CSI-ReportConfig).

[0087] For example, the terminal device is configured with a first CSI report through a first CSI report configuration (LTM-CSI-ReportConfig), and the first CSI report is a CSI report related to LTM, for example, a CSI report performed for LTM purposes (cell switching purposes), and the terminal device may be provided with multiple first CSI report configurations, each first CSI report configuration is associated with a CSI report configuration identifier (LTM-CSI-ReportConfigId), for example, the first CSI report may also be referred to as an LTM CSI report; for example, the terminal device is configured with a second CSI report through a second CSI report configuration (CSI-ReportConfig), and the second CSI report is a CSI report unrelated to LTM, that is, a CSI report performed for non-LTM purposes, and the terminal device may be provided with multiple second CSI report configurations, each second CSI report configuration is associated with a CSI report configuration identifier (CSI-ReportConfigId), for example, the second CSI report may also be referred to as a traditional CSI report.

[0088] In some embodiments, a first CSI report and / or a second CSI report is associated with a priority value. For example, each CSI report is associated with a priority value, the first CSI report is associated with a first priority value, i.e., the first priority value of the first CSI report, and the second CSI report is associated with a second priority value, i.e., the second priority value of the second CSI report.

[0089] In some embodiments, the priority of the first CSI report and / or the second CSI report is determined based on at least one of: a first priority value of the first CSI report; a second priority value of the second CSI report; or a first rule.

[0090] In some embodiments, the smaller the first priority value, the higher the priority of the corresponding first CSI report, and / or the smaller the second priority value, the higher the priority of the corresponding second CSI report.

[0091] For example, within the first CSI report or the second CSI report, the smaller the first priority value, the higher the priority of the corresponding first CSI report; or the smaller the second priority value, the higher the priority of the corresponding second CSI report:

[0092] For example, within the first CSI report, the value range of the first priority value is an integer from 0 to N. As the first priority value increases, the priority of the corresponding first CSI report decreases. For example, the priority of the first CSI report with the first priority value of "n1" is higher than that of the first CSI report with the first priority value of "n2", where n1 < n2; the method for determining the priority within the second CSI report is similar to that within the first CSI report and will not be repeated here.

[0093] The above method is also applicable to determining the priority between the first CSI report and the second CSI report. For example, between the first CSI report and the second CSI report: the smaller the first priority value, the higher the priority of the corresponding first CSI report, and the smaller the second priority value, the higher the priority of the corresponding second CSI report.

[0094] For example, between the first CSI report and the second CSI report, when the first priority value and the second priority value are different, for example, the priority of the first CSI report with the first priority value of "n1" is higher than that of the second CSI report with the second priority value of "m1", where n1 < m1; the case where the first priority value and the second priority value are the same will be introduced in detail later and will not be repeated here.

[0095] In some embodiments, sending the first CSI report and / or the second CSI report includes: sending the CSI report with a higher priority among the first CSI report and the second CSI report.

[0096] For example, the terminal device needs to send multiple CSI reports including the first CSI report and the second CSI report at the same time and needs to select a part of the CSI reports for sending. For example, the terminal device selects 5 CSI reports out of 10 CSI reports including the first CSI report and the second CSI report for reporting. During the process of selecting a specific CSI report, for example, when selecting the 5th of the 5 CSI reports to be reported, if the terminal device needs to select one CSI report to send between the first CSI report and the second CSI report, the terminal device selects the CSI report with a higher priority for sending.

[0097] Figure 4 illustrates an example of simultaneously and non-simultaneously sending a first CSI report and a second CSI report in an embodiment of the present application. For example, as shown in the left figure of Figure 4 , a terminal device may need to simultaneously send multiple CSI reports, including the first CSI report and the second CSI report, in the time domain. For example, as shown in the right figure of Figure 4 , a terminal device may also send multiple CSI reports, including the first CSI report and the second CSI report, at different times in the time domain.

[0098] For example, “the terminal device needs to simultaneously send multiple CSI reports including a first CSI report and a second CSI report” includes “the terminal device simultaneously sends multiple CSI reports including a first CSI report and a second CSI report on one cell”.

[0099] For example, when a terminal device needs to simultaneously send multiple CSI reports including a first CSI report and a second CSI report in the time domain, the terminal device needs to determine the priority of the first CSI report and the second CSI report. The following describes how to determine the "CSI report with a higher priority between the first CSI report and the second CSI report":

[0100] For example, the terminal device determines the priority of the first CSI report and / or the second CSI report according to the first priority value of the first CSI report, the second priority value of the second CSI report, and the first rule.

[0101] In some embodiments, the first rule includes: when the first priority value is the same as the second priority value, the priority of the first CSI report corresponding to the first priority value is higher than the priority of the second CSI report corresponding to the second priority value; or, when the first priority value is the same as the second priority value, the priority of the second CSI report corresponding to the second priority value is higher than the priority of the first CSI report corresponding to the first priority value.

[0102] The following is an example of "when the first priority value and the second priority value are the same, the priority of the first CSI report corresponding to the first priority value is higher than the priority of the second CSI report corresponding to the second priority value":

[0103] For example, since the first CSI report and the second CSI report are configured independently, it is possible that the first priority value is the same as the second priority value. When the terminal device needs to select one CSI report (a CSI report with a higher priority) from the first CSI report and the second CSI report to send, for example, when the first CSI report and the second CSI report need to be sent at the same time, only one of the CSI reports can be selected to send. Since the priority of the first CSI report and the second CSI report cannot be determined according to the size of the priority value at this time, the terminal device can follow the default first rule; for example, when the first priority value is the same as the second priority value, the terminal device always believes that the priority of the first CSI report corresponding to the first priority value is higher than the priority of the second CSI report corresponding to the second priority value, for example, it believes that the CSI report related to LTM has a higher priority, and thus selects the first CSI report to send; when the first priority value is different from the second priority value, the CSI report with a smaller priority value still has a higher priority.

[0104] In this way, the priority between the first CSI report and the second CSI report can be determined, and the ambiguity problem caused when determining the priority of the CSI report is solved.

[0105] Figure 5 is an example diagram of determining the priorities of the first and second CSI reports according to an embodiment of the present application. As shown in Figure 5, for example, the first priority value of the first CSI report is the same as the second priority value of the second CSI report. Since the priority values ​​of first CSI report #1 and second CSI report #3 are the same, first CSI report #1 takes precedence over second CSI report #3; since second CSI report #3 has a lower priority value than first CSI report #2, second CSI report #3 takes precedence over first CSI report #2; and since first CSI report #2 has a lower priority value than second CSI report #4, first CSI report #2 takes precedence over second CSI report #4. Thus, it can be determined that the priority of the first and second CSI reports is, from high to low, first CSI report #1, second CSI report #3, first CSI report #2, and second CSI report #4.

[0106] The following is an example of "when the first priority value and the second priority value are the same, the second CSI report corresponding to the second priority value has a higher priority than the first CSI report corresponding to the first priority value":

[0107] For example, since the first CSI report and the second CSI report are configured independently, it is possible that the first priority value and the second priority value are the same. When the terminal device needs to select one CSI report (a CSI report with a higher priority) from the first CSI report and the second CSI report to send, for example, when the first CSI report and the second CSI report need to be sent at the same time, only one of the CSI reports can be selected to send. Since the priority of the first CSI report and the second CSI report cannot be determined according to the size of the priority value at this time, the terminal device can follow the default first rule; for example, when the first priority value and the second priority value are the same, the terminal device always believes that the priority of the second CSI report corresponding to the second priority value is higher than the priority of the first CSI report corresponding to the first priority value, for example, it believes that the CSI report that is not related to LTM has a higher priority, and thus selects the second CSI report to send; when the first priority value and the second priority value are different, the CSI report with a smaller priority value still has a higher priority.

[0108] For example, still taking Figure 5 as an example, the priority of the first CSI report and the second CSI report is in the order of second CSI report #3, first CSI report #1, first CSI report #2, and second CSI report #4 from high to low.

[0109] In this way, the priority between the first CSI report and the second CSI report can be determined, and the ambiguity problem caused when determining the priority of the CSI report is solved.

[0110] In some embodiments, the first rule includes: considering the priority of the first CSI report to be higher than the priority of the second CSI report, or considering the priority of the second CSI report to be higher than the priority of the first CSI report.

[0111] For example, the terminal device may follow a default first rule, such as, between a first CSI report and a second CSI report, the terminal device always considers the first CSI report to have a higher priority than the second CSI report; for example, the terminal device always considers the CSI report associated with LTM to have a higher priority; and, within a first CSI report or a second CSI report, the priority of the first CSI report or the second CSI report is still determined according to the first priority value or the second priority value. For example, among multiple first CSI reports, the smaller the first priority value, the higher the priority of the corresponding first CSI report; and among multiple second CSI reports, the smaller the second priority value, the higher the priority of the corresponding second CSI report.

[0112] For example, still taking Figure 5 as an example, the priority of the first CSI report and the second CSI report is in the order of first CSI report #1, first CSI report #2, second CSI report #3, and second CSI report #4 from high to low.

[0113] In this way, the priority between the first CSI report and the second CSI report can be determined, and the ambiguity problem caused when determining the priority of the CSI report is solved.

[0114] For example, the terminal device may follow a default first rule, such as, between a first CSI report and a second CSI report, the terminal device always considers the second CSI report to have a higher priority than the first CSI report; for example, the terminal device considers that a CSI report not related to LTM always has a higher priority; and, within a first CSI report or a second CSI report, the priority of the first CSI report or the second CSI report is still determined according to the size of the first priority value or the second priority value. For example, among multiple first CSI reports, the smaller the first priority value, the higher the priority of the corresponding first CSI report; and among multiple second CSI reports, the smaller the second priority value, the higher the priority of the corresponding second CSI report.

[0115] For example, still taking Figure 5 as an example, the priority of the first CSI report and the second CSI report is in the order of second CSI report #3, second CSI report #4, first CSI report #1, and first CSI report #2 from high to low.

[0116] In this way, the priority between the first CSI report and the second CSI report can be determined, and the ambiguity problem caused when determining the priority of the CSI report is solved.

[0117] In some embodiments, being configured with the first CSI report (CSI report) and / or the second CSI report (CSI report) includes: not desiring to configure the first CSI report and the second CSI report with the same priority value.

[0118] For example, the statement "the terminal device does not expect to be configured with the first CSI report and the second CSI report having the same priority value" can also be replaced by "the terminal device expects to be configured with the first CSI report and the second CSI report having different priority values" or "the network device does not configure / schedule / indicate the first CSI report and the second CSI report having the same priority value" or "the serving cell does not configure / schedule / indicate the first CSI report and the second CSI report having the same priority value"; for example, "the first CSI report and the second CSI report having the same priority value" means that the first priority value (priority value) of the first CSI report is equal to the second priority value (priority value) of the second CSI report.

[0119] For example, the priority values ​​of the first CSI report and the second CSI report depend on the CSI report configuration. For example, for the configuration shown in Table 1, the terminal device does not expect to be provided with a first CSI report configuration (LTM-CSI-ReportConfig) and a second CSI report configuration (CSI-ReportConfig) such that the first priority value is the same as the second priority value. In the case where the first priority value is different from the second priority value, the CSI report with a smaller priority value has a higher priority. Thus, by restricting the configuration of the first CSI report and the second CSI report with the same priority value for the terminal device, the ambiguity problem caused by determining the priority of the CSI report is resolved.

[0120] For another example, the priority values ​​of the first CSI report and the second CSI report depend on one or more parameters related to the CSI report configuration (or in the CSI report configuration). When at least one of the parameters is configured differently, the priority values ​​of the two CSI reports are different.

[0121] For example, the one or more parameters related to the CSI report configuration (or in the CSI report configuration) include at least a "CSI report configuration identifier (CSI report configuration ID)".

[0122] In some embodiments, being configured with the first CSI report (CSI report) and / or the second CSI report (CSI report) includes: not expecting to be configured with the first CSI report and the second CSI report having the same CSI report configuration identifier (CSI report configuration ID).

[0123] In some embodiments, not expecting the first CSI report and the second CSI report to be configured with the same priority value includes: not expecting the first CSI report and the second CSI report to be configured with the same CSI report configuration identifier (CSI report configuration ID).

[0124] For example, the statement “the terminal device does not expect to be configured with the first CSI report and the second CSI report having the same CSI report configuration identifier (CSI report configuration ID)” can also be replaced with “the terminal device expects to be configured with the first CSI report and the second CSI report having different CSI report configuration identifiers (CSI report configuration IDs)” or “the network device does not configure / schedule / indicate the first CSI report and the second CSI report having the same CSI report configuration identifier (CSI report configuration ID)” or “the serving cell does not configure / schedule / indicate the first CSI report and the second CSI report having the same CSI report configuration identifier (CSI report configuration ID)”.

[0125] For example, “a first CSI report and a second CSI report having the same priority value” means that a first priority value of the first CSI report is equal to a second priority value of the second CSI report.

[0126] For example, the one or more parameters related to the CSI report configuration (or in the CSI report configuration) include at least a "CSI report configuration ID." When the "CSI report configuration ID" of the first CSI report and the second CSI report are configured with different values, the first priority value of the first CSI report is different from the second priority value of the second CSI report. When the first priority value and the second priority value are different, the CSI report with a smaller priority value has a higher priority.

[0127] For example, for the configuration shown in Table 1, such as "maxNrofLTMCSI-ReportConfigurations" = "maxNrofCSI-ReportConfigurations" = N, then the maximum number of the first CSI report and the second CSI report is the same. By configuring different "CSI report configuration identifiers" for the terminal device, the total number of the first CSI report and the second CSI report does not exceed N, that is, it is still equal to the maximum number of CSI reports (N) before the introduction of LTM, and thus there is no need to introduce new terminal device capabilities; without restricting "configuring different "CSI report configuration identifiers" for the terminal device", the total number of the first CSI report and the second CSI report can reach a maximum of 2N, and new terminal device capabilities need to be introduced to support higher complexity.

[0128] Therefore, by limiting the configuration of the first CSI report and the second CSI report for the terminal device to correspond to different "CSI report configuration identifiers", the ambiguity problem caused by determining the priority of the CSI report is solved while further reducing the complexity of the terminal device, avoiding requiring the terminal device to support more CSI reports and avoiding the introduction of new terminal device capabilities.

[0129] In some implementations, sending the first CSI report and / or the second CSI report includes not expecting to send the first CSI report and the second CSI report simultaneously.

[0130] In some implementations, not expecting to send the first CSI report and the second CSI report simultaneously includes: not expecting to send the first CSI report and the second CSI report simultaneously on a cell.

[0131] For example, “the terminal device does not expect to send the first CSI report and the second CSI report at the same time” includes: “the terminal device does not expect to send the first CSI report and the second CSI report at the same time on one cell”.

[0132] For example, the statement "the terminal device does not expect to send the first CSI report and the second CSI report at the same time" can also be replaced by "the terminal device is not scheduled to send the first CSI report and the second CSI report at the same time" or "the terminal device expects (expects) not to send the first CSI report and the second CSI report at the same time" or "the network device does not configure / schedule / instruct to send the first CSI report and the second CSI report at the same time" or "the serving cell does not configure / schedule / instruct to send the first CSI report and the second CSI report at the same time".

[0133] For example, still taking Figure 4 as an example, "the terminal device does not expect to send the first CSI report and the second CSI report at the same time" includes that the terminal device does not expect to send the first CSI report and the second CSI report according to the example shown in the left figure of Figure 4; or, "the terminal device does not expect to send the first CSI report and the second CSI report at the same time" includes that the network device is scheduled to send the first CSI report and the second CSI report according to the example shown in the right figure of Figure 4.

[0134] For example, the network device indicates the sending of the first CSI report and the second CSI report in the time domain through dynamic signaling (e.g., MAC Control Element (MAC CE) or downlink control information (DCI)) or through semi-static signaling (e.g., RRC message).

[0135] Because ambiguity in determining the priority of CSI reports may arise only when a terminal device needs to send a first CSI report and a second CSI report simultaneously, and the first and second CSI reports have the same priority value, by restricting scheduling so that the terminal device does not need to send the first and second CSI reports simultaneously, the terminal device does not need to compare the priorities of the first and second CSI reports, thereby resolving the ambiguity in determining the priority of CSI reports. Among multiple first CSI reports, or among multiple second CSI reports, the CSI report with a smaller priority value still has a higher priority.

[0136] In some embodiments, sending the first CSI report and / or the second CSI report includes not expecting to send the first CSI report and the second CSI report having the same priority value at the same time.

[0137] In some embodiments, not expecting the first CSI report and the second CSI report having the same priority value to be sent simultaneously includes not expecting the first CSI report and the second CSI report having the same priority value to be sent simultaneously on a cell.

[0138] For example, the statement "the terminal device does not expect to simultaneously send the first CSI report and the second CSI report having the same priority value" can also be replaced by "the terminal device is not scheduled to simultaneously send the first CSI report and the second CSI report having the same priority value" or "the network device does not configure / schedule / instruct to simultaneously send the first CSI report and the second CSI report having the same priority value" or "the serving cell does not configure / schedule / instruct to simultaneously send the first CSI report and the second CSI report having the same priority value".

[0139] For example, “a first CSI report and a second CSI report having the same priority value” means that a first priority value of the first CSI report is equal to a second priority value of the second CSI report.

[0140] For example, by restricting scheduling so that a terminal device does not need to simultaneously transmit a first CSI report and a second CSI report having the same priority, ambiguity in determining the priorities of the first and second CSI reports is avoided. For example, the first and second CSI reports may have the same priority value and may be scheduled simultaneously, but the terminal device will not be scheduled to simultaneously transmit the first and second CSI reports having the same priority value. Even if the priority values ​​are different, the CSI report with the lower priority value still has a higher priority.

[0141] For example, "the terminal device does not expect to simultaneously send the first CSI report and the second CSI report having the same priority value" includes that the network device can schedule the simultaneous sending of the first CSI report and the second CSI report, for example, the network device instructs the simultaneous sending of the first CSI report and the second CSI report through dynamic signaling (for example, MAC Control Element (MAC CE) or downlink control information (DCI)) or through semi-static signaling (for example, RRC message), wherein the priority values ​​corresponding to the first CSI report and the second CSI report sent simultaneously are different, that is, the first priority value of the first CSI report is different from the second priority value of the second CSI report.

[0142] Since ambiguity in determining the priority of CSI reports may only occur when a terminal device needs to send the first CSI report and the second CSI report at the same time, and the priority values ​​of the first CSI report and the second CSI report are the same, therefore, by restricting the scheduling so that the terminal device does not need to send the first CSI report and the second CSI report with the same priority value at the same time, that is, the priorities of the first CSI report and the second CSI report sent by the terminal device at the same time will not be ambiguous, the ambiguity problem caused by determining the priority of CSI reports is solved. In the case of different priority values, the CSI report with a smaller priority value still has a higher priority.

[0143] In some embodiments, sending the first CSI report and / or the second CSI report includes: not expecting to send the first CSI report and the second CSI report having the same CSI reporting configuration identifier at the same time.

[0144] In some implementations, not expecting to send the first CSI report and the second CSI report with the same CSI report configuration identifier at the same time includes: not expecting to send the first CSI report and the second CSI report with the same CSI report configuration identifier on a cell at the same time.

[0145] For example, when the "CSI report configuration identifier" is different, the priority value of the corresponding CSI report is different; in the case of different priority values, the CSI report with a smaller priority value still has a higher priority; for example, the statement "the terminal device does not expect to simultaneously send the first CSI report and the second CSI report with the same CSI report configuration identifier" can also be replaced by "the terminal device is not scheduled to simultaneously send the first CSI report and the second CSI report with the same CSI report configuration identifier" or "the network device does not configure / schedule / instruct to simultaneously send the first CSI report and the second CSI report with the same CSI report configuration identifier" or "the service cell does not configure / schedule / instruct to simultaneously send the first CSI report and the second CSI report with the same CSI report configuration identifier".

[0146] In some implementations, not expecting to simultaneously send the first CSI report and the second CSI report having the same priority value includes: not expecting to simultaneously send the first CSI report and the second CSI report having the same CSI report configuration identifier.

[0147] For example, the statement “the terminal device does not expect to simultaneously send the first CSI report and the second CSI report having the same priority value” can also be replaced by “the terminal device does not expect to simultaneously send the first CSI report and the second CSI report having the same CSI report configuration identifier”.

[0148] Since ambiguity in determining the priority of the CSI report may only occur when the terminal device needs to send the first CSI report and the second CSI report at the same time, and the priority values ​​of the first CSI report and the second CSI report are the same, therefore, by restricting the scheduling so that the terminal device does not need to send the first CSI report and the second CSI report with the same CSI report configuration identifier (that is, with the same priority value) at the same time, that is, the priorities of the first CSI report and the second CSI report sent by the terminal device at the same time will not be ambiguous, the ambiguity problem caused by determining the priority of the CSI report is solved. In the case of different priority values, the CSI report with a smaller priority value still has a higher priority.

[0149] In some embodiments, the first priority value and / or the second priority value is determined based on at least one of: a CSI report configuration identifier; a serving cell index; a CSI report quantity; a CSI report configuration type; or whether the CSI report is related to LTM.

[0150] In some embodiments, the first priority value and / or the second priority value is determined based on a parameter representing a CSI report configuration identifier, a parameter representing a serving cell index, a parameter representing a CSI report amount, and a parameter representing a CSI report configuration type.

[0151] The first priority value and the second priority value are represented as Pri CSI ,Pri CSI Determine according to the following formula (1): Pri CSI (y,k,c,s)=M k ·N cells ·M s y+N cells ·M s k+M s ·c+s (1)

[0152] in,

[0153] -y represents the CSI reporting configuration type. For example, for aperiodic CSI reporting carried by the Physical Uplink Shared Channel (PUSCH), y = 0; for semi-persistent CSI reporting carried by PUSCH, y = 1; for semi-persistent CSI reporting carried by the Physical Uplink Control Channel (PUCCH), y = 2; for periodic CSI reporting carried by PUCCH, y = 3.

[0154] -k indicates the CSI report amount, M k -1 represents the maximum value of k. For example, for CSI reports carrying L1-RSRP or L1-SINR (Signal to Interference plus Noise Ratio), k = 0; for CSI reports not carrying L1-RSRP or L1-SINR, k = 1; Here M k =2.

[0155] -c indicates the serving cell index, N cells -1 represents the maximum value of c. For example, c represents the cell where the CSI report is located, that is, the CSI report is sent on the serving cell c; N cells It is the parameter maxNrofSrevingCells configured by the higher layer, that is, the maximum number of serving cells.

[0156] -s indicates the CSI report configuration flag, M s -1 indicates the maximum value of s. For example, as shown in Table 1, for the first CSI report, s is the parameter LTM-CSI-ReportConfigId configured by the higher layer, M s is the parameter maxNrofLTMCSI-ReportConfigurations configured by the higher layer; for the second CSI report, s is the parameter CSI-ReportConfigId configured by the higher layer, M s It is the parameter maxNrofCSI-ReportConfigurations configured by the higher layer.

[0157] FIG6 is an example diagram illustrating how to determine a first priority value and / or a second priority value according to an embodiment of the present application. For example, formula (1) can be represented as a tree diagram as shown in FIG6 , where a CSI report corresponds to a bottom-level branch in the diagram and has a priority value; for example, both the first priority value and the second priority value can be determined according to formula (1).

[0158] For example, the first priority value or the second priority value is determined according to FIG6 and the formula (1), according to M s The value range of the first priority value and the second priority value may be the same. The priority of the first CSI report and the second CSI report can be determined according to the following first rule. For example, the first rule includes: when the first priority value and the second priority value are the same, the priority of the first CSI report corresponding to the first priority value is higher than the priority of the second CSI report corresponding to the second priority value, or when the first priority value and the second priority value are the same, the priority of the second CSI report corresponding to the second priority value is higher than the priority of the first CSI report corresponding to the first priority value. In the case where the priority values ​​are different, the CSI report with the smaller priority value still has a higher priority.

[0159] In this way, the priority values ​​of the first CSI report and the second CSI report can be determined, which solves the ambiguity problem caused when determining the priority of the CSI report.

[0160] In some embodiments, the first priority value or the second priority value is determined based on a parameter representing a CSI report configuration identifier, a parameter representing a serving cell index, a parameter representing a CSI report amount and / or whether the CSI report is related to LTM, and a parameter representing a CSI report configuration type.

[0161] The first priority value and the second priority value are represented as Pri CSI ,Pri CSI Determine according to the following formula (2): Pri CSI (y,k,c,s)=M k ·N cells ·M s y+N cells ·M s k+M s ·c+s (2)

[0162] in,

[0163] -k indicates the amount of CSI reports and / or whether the CSI reports are related to LTM, M k -1 represents the maximum value of k. For example, for CSI reports that carry L1-RSRP or L1-SINR and are not related to LTM, k = 1; for CSI reports that do not carry L1-RSRP or L1-SINR and are not related to LTM, k = 2; for CSI reports that are related to LTM, k = 0; Here M k=3. This application does not impose any restrictions on which type of CSI report corresponds to which value of k. For example, the three types of CSI reports mentioned above may also be: k=0 for a CSI report that carries L1-RSRP or L1-SINR and is not related to LTM, k=1 for a CSI report that does not carry L1-RSRP or L1-SINR and is not related to LTM, and k=2 for a CSI report that is related to LTM. For example, k may also take other values, which are not listed here one by one.

[0164] -The definitions of other parameters are the same as those in formula (1).

[0165] FIG7 is another example diagram for determining a first priority value and / or a second priority value according to an embodiment of the present application. Formula (2) can be represented as a tree diagram of FIG7 . Both the first priority value and the second priority value can be determined according to Formula (2). The difference from Formula (1) is that Formula (2) expands the range of k, thereby adding a new branch for the first CSI report.

[0166] For example, the first priority value or the second priority value is determined in accordance with FIG7 and the method shown in formula (2). As a result, the first CSI report and the second CSI report will not have the same priority value, thereby resolving the ambiguity problem caused by determining the priority of the CSI reports. In the case of different priority values, the CSI report with a smaller priority value has a higher priority.

[0167] In some embodiments, the first priority value or the second priority value is determined based on a parameter representing a CSI report configuration identifier, a parameter representing a serving cell index, a parameter representing a CSI report amount, a parameter representing a CSI report configuration type, and a parameter representing whether the CSI report is related to LTM.

[0168] The first priority value and the second priority value are represented as Pri CSI ,Pri CSI Determine according to the following formula (3): Pri CSI (y,k,c,s)=M y ·M k ·N cells ·M s ·x+M k ·N cells ·M s y+N cells ·M s k+M s · c+s (3)

[0169] in,

[0170] -x indicates whether the CSI report is related to LTM. For example, when the CSI report is not related to LTM (traditional CSI report), x = 0; when the CSI report is related to LTM (LTM CSI report), x = 1. This application does not restrict which CSI report corresponds to which value of x. For example, the two CSI reports mentioned above may also be: x = 1 for the traditional CSI report and x = 0 for the LTM CSI report. For example, x may also take other values, which are not listed here one by one.

[0171] -M y -1 represents the maximum value of y. For example, the definition of y is the same as formula (1), M y =4.

[0172] -The definitions of other parameters are the same as those in formula (1).

[0173] FIG8 is another example diagram of determining the first priority value and / or the second priority value according to an embodiment of the present application. Formula (3) can be expressed as a tree diagram of FIG8. Both the first priority value and the second priority value can be determined according to Formula (3).

[0174] For example, the first priority value or the second priority value is determined in the manner shown in FIG8 and formula (3). Formula (3) introduces a new parameter x, thereby adding a new branch to the first CSI report. As a result, the first CSI report and the second CSI report will not have the same priority value, thereby resolving the ambiguity problem caused by determining the priority of the CSI report.

[0175] In Figure 8, the newly introduced parameter x is located in the first branch (counting from top to bottom). When the parameter x is located in the first branch, Pri CSI Determined according to formula (3); similarly, parameter x can be located in the second, third, fourth, and fifth branches.

[0176] The following is a schematic illustration of the situations where the parameter x is located in different branches:

[0177] FIG9 is another example diagram of determining the first priority value and / or the second priority value according to an embodiment of the present application. As shown in FIG9 , when the parameter x is located in the second branch, Pri CSI Determined according to formula (4); Pri CSI (y,k,c,s)=M x ·M k ·N cells ·M s y+M k ·N cells ·M s x+N cells ·M s k+Ms · c+s (4)

[0178] in,

[0179] -M x -1 represents the maximum value of x. For example, the definition of x is the same as formula (3), M x =2.

[0180] -The definitions of other parameters are the same as those in formula (3).

[0181] When the parameter x is in the third branch, Pri CSI Determined according to formula (5); Pri CSI (y,k,c,s)=M k ·M x ·N cells ·M s y+M x ·N cells ·M s k+N cells ·M s ·x+M s · c+s (5)

[0182] When the parameter x is in the fourth branch, Pri CSI Determined according to formula (6); Pri CSI (y,k,c,s)=M k ·N cells ·M x ·M s y+N cells ·M x ·M s k+M x ·M s c+M s · x+s (6)

[0183] When the parameter x is in the fifth branch, Pri CSI Determine according to formula (7): Pri CSI (y,k,c,s)=M k ·N cells ·M s ·M x y+N cells ·M s ·M x k+M s ·M x c+Mx · s+x (7)

[0184] For example, for formulas (5)-(7), the definition of the parameters is the same as that of formula (4); for example, formulas (4)-(7) are variations of formula (3). Thus, after determining the first priority value and / or the second priority value according to formulas (4)-(7), the first CSI report and the second CSI report will not have the same priority value, thereby resolving the ambiguity problem caused when determining the priority of the CSI report.

[0185] For example, the first priority value of the first CSI report and the second priority value of the second CSI report are determined according to the above formula. For example, the first priority value and the second priority value determined according to formula (1) may be the same, and the first priority value and the second priority value determined according to formulas (2)-(7) will not be the same.

[0186] For example, for formula (1), when the determined first priority value is the same as the second priority value, ambiguity will arise in determining the priority. The ambiguity problem generated when determining the priority of the CSI report is solved by using the method described above. For example, the priority of the first CSI report is defined as higher by the first rule, or the priority of the second CSI report is defined as higher by the first rule. For example, the first rule includes: when the first priority value is the same as the second priority value, the priority of the first CSI report corresponding to the first priority value is higher than the priority of the second CSI report corresponding to the second priority value, or when the first priority value is the same as the second priority value, the priority of the second CSI report corresponding to the second priority value is higher than the priority of the first CSI report corresponding to the first priority value. For formulas (2)-(7), since the determined first priority value and the second priority value are not the same, no ambiguity will arise when determining the "priority of the first CSI report and the second CSI report". According to the principle that "the smaller the priority value of the CSI report, the higher the priority of the CSI report", the "priority of the first CSI report and the second CSI report" can be determined. The ambiguity problem generated when determining the priority of the CSI report is solved by formulas (2)-(7).
