[0002] Reducing antenna power in 5G (5th Generation Mobile Communication Technology) networks is an important direction for reducing overall network energy consumption. By flexibly shutting down antenna ports and adjusting antenna transmit power, the network energy consumption of base station signals can be reduced as much as possible.

[0003] In order to achieve this function, multiple CSI-RS patterns and transmit powers can be configured in one CSI-RS (Channel State Information-ReferenceSignal) resource configuration (CSI-RS Resource Configuration), so that the base station can make timely adjustments to the transmit antenna distribution and power. In order to improve configuration efficiency, a mechanism for simultaneously configuring, measuring and reporting multiple CSI-RS resources is introduced.

[0036] The technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present disclosure and its application or use. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0037] The present disclosure provides an information reporting indication method, which is combined with Figure 1 Give a description.

[0038] Figure 1 The following is a flowchart of some embodiments of the method for indicating information reporting of the present disclosure. Figure 1 As shown, the method of this embodiment includes: steps S102 to S104.

[0039] In step S102, the base station sends CSI reporting configuration information to the terminal, and correspondingly, the terminal receives the CSI reporting configuration information sent by the base station.

[0040] In some embodiments, the CSI reporting configuration information may be a CSI reporting configuration (CSI-ReportConfig) IE (Information Element) in RRC (Radio Resource Control) signaling.

[0041] In some embodiments, the CSI reporting configuration information includes: first indication information, used to indicate whether the measurement result of each measurement information of multiple CSI-RSs is jointly reported.

[0042] The measurement results of various measurement information of CSI-RS (also referred to as fields to be measured, measurement content, etc.) can be collectively referred to as CSI, including: CRI (CSI-RS Resource Indicator), RI (Rank Indicator), PMI (Precoding Matrix Indicator), CQI (Channel Quality Indicator), etc., and reference can be made to existing standards, not limited to the examples given. The base station can configure multiple CSI-RS resources for the terminal and send CSI-RS. The terminal performs measurements on multiple CSI-RS resources to obtain measurement results of various measurement information, that is, obtains various CSIs and reports them to the base station.

[0043] Various measurement information of CSI-RS can be configured through the reportQuantity information element. For example, reportQuantity can be configured as "none", "cri-RI-PMI-CQI", "cri-RI-i1", "cri-RI-i1-CQI", etc., and can refer to existing standards, but is not limited to the examples given.

[0044] Joint reporting can also be called shared reporting, that is, multiple measurement results are jointly reported using a shared value. For example, the CRI of multiple CSI-RSs are jointly reported using a shared value, and the CQI of multiple CSI-RSs are jointly reported using another shared value.

[0045] The first indication information is used to indicate whether the measurement result of each measurement information in the reporting quantity (reportQuantity) information elements of the multiple CSI-RSs is jointly reported.

[0046] In some embodiments, the length of the first indication information is determined according to the number of measurement information items in the reportQuantity information element. For example, when reportQuantity is configured as 'cri-RI-PMI-CQI', the length of the first indication information is 4 bits.

[0047] In some embodiments, the first indication information is indicated in a bitmap manner, and the length of the bitmap is determined by the number of measurement information items in the reported quantity cell. Each bit in the bitmap of the first indication information corresponds to each measurement information item in the reported quantity cell. The bits corresponding to each measurement information item in the reported quantity cell are arranged in the order of each measurement information item in the reported quantity cell. Each bit indicates whether the measurement result of the corresponding measurement information is reported jointly.

[0048] For example, when reportQuantity is configured as 'cri-RI-PMI-CQI', the length of the first indication information is 4 bits, and each bit represents whether cri, RI, PMI, and CQI are reported in a joint reporting manner. For example, when each bit is 1, it indicates that it is reported in a joint reporting manner, and when it is 0, it indicates that it is reported in an independent reporting manner. If cri, RI, and PMI are all reported in a joint reporting manner, and CQI is reported in an independent reporting manner, the first indication information can be configured as 1110.

[0049] In some embodiments, the first indication information is configured in a reporting format information element. A new ReportFormat (reporting format) IE may be added and configured in a CSI reporting configuration (CSI-ReportConfig) IE to carry the first indication information.

[0050] In some embodiments, when the CSI reporting configuration information includes multiple sub-configuration information, the first indication information includes first indication information corresponding to each sub-configuration information, which is used to indicate whether the measurement result of each measurement information of the CSI-RS corresponding to each sub-configuration information is jointly reported.

[0051] To facilitate specific configuration of the system, a sub-configuration method may be introduced in the CSI reporting configuration, where each sub-configuration has the same characteristics (such as the number of antenna ports) to improve the efficiency of the reporting configuration.

[0052] If there is sub-configuration information in the CSI reporting configuration information, a first indication information (ReportFormat IE) is configured for each sub-configuration information. Of course, a first indication information can also be used to indicate a reporting mode applicable to CSI-RS in multiple sub-configuration information.

[0053] For example, the base station configures 3 CSI-RS resources with a port number of 16 and 3 CSI-RS with a port number of 32 for the terminal. In the CSI reporting configuration, the 3 CSI-RS resources with a port number of 16 can be attributed to the same sub-configuration A, and the 3 CSI-RS with a port number of 32 can be attributed to the same sub-configuration B. In the CSI reporting configuration, when reportQuantity is configured as "cri-RI-PMI-CQI", the first indication information (ReportFormat IE) of sub-configuration A is configured as "1111", indicating that the cri, RI, PMI, and CQI of the 3 CSI-RS in sub-configuration A are all reported in a joint reporting manner, and the first indication information (ReportFormat IE) of sub-configuration B is configured as "1100", indicating that the cri and RI of the 3 CSI-RS in sub-configuration B are reported in a joint reporting manner, and PMI and CQI are reported in an independent reporting manner.

[0054] In some embodiments, the CSI reporting configuration information includes: second indication information, used to indicate whether the CSI of multiple CSI-RSs is reported jointly. That is, the second indication information is used to indicate whether the measurement results of part or all of the measurement information of multiple CSI-RSs are reported in a joint reporting manner. The second indication information can be configured separately or together with the first indication information. That is, the CSI reporting configuration information can include only the first indication information or the second indication information, or can include the first indication information and the second indication information.

[0055] For example, when the second indication information is configured separately, it is used to indicate whether the measurement results of all measurement information of multiple CSI-RS (all CSI) are reported in a joint reporting manner. For example, when the second indication information is configured as 1, it indicates that the measurement results of all measurement information of multiple CSI-RS are reported jointly, and when the second indication information is configured as 0, it indicates that the measurement results of all measurement information of multiple CSI-RS are not reported jointly, but reported in an independent reporting manner.

[0056] For example, when the second indication information and the first indication information are configured together, the second indication information is used to indicate whether the measurement results of part or all of the measurement information of multiple CSI-RSs (part or all of the CSI) are reported in a joint reporting manner. For example, when one or more measurement results of each of the measurement information of multiple CSI-RSs indicated by the first indication information are jointly reported, the second indication information is configured to be 1 (first value), indicating that the CSI of multiple CSI-RSs is jointly reported, otherwise the second indication information is configured to be 0 (second value).

[0057] When the second indication information and the first indication information are configured together, the priority of the second indication information is higher than that of the first indication information. That is, as long as the first indication information (ReportFormat) is configured, the terminal is required to report the measurement result with reference to the indication of ReportFormat.

[0058] In some embodiments, the second indication information is configured in a shared reporting flag information element. A new ShareReportFlag IE (shared reporting flag information element) may be added to the CSI reporting configuration (CSI-ReportConfig) IE to carry the second indication information. If the specific value of the second indication information is not configured, it may default to 0 (the second value), indicating that the CSI of multiple CSI-RSs is not reported in a joint reporting manner, but in an independent reporting manner.

[0059] In some embodiments, when the CSI reporting configuration information includes multiple sub-configuration information, the second indication information includes second indication information corresponding to each sub-configuration information, which is used to indicate whether the CSI (partial or all measurement results) of the CSI-RS corresponding to each sub-configuration information is reported in a joint reporting manner.

[0060] If a sub-configuration method is introduced in the CSI reporting configuration, a second indication information (ShareReportFlag IE) may be configured for each sub-configuration to take effect on the CSI-RS in the sub-configuration; or the same ShareReportFlag IE may be configured for the entire CSI-ReportConfig IE, and all CSI measurements in the configuration shall be reported with reference to this indication.

[0061] In some embodiments, the CSI reporting configuration information includes: third indication information, the third indication information is used to indicate the CSI-RS corresponding to the CSI that can be jointly reported. The CSI-RS corresponding to the CSI that can be jointly reported can form a reporting group (Report Group), that is, the CSI (measurement results of measurement information) of multiple CSI-RS in the reporting group can be reported in a jointly reporting manner.

[0062] The third indication information may be configured in a bitmap manner, a list manner, etc., and is not limited to the examples given. For example, the third indication information is configured in a bitmap manner, and each bit in the bitmap of the third indication information corresponds to multiple CSI-RSs one by one.

[0063] The third indication information adopts a bitmap to indicate all CSI-RS contained in each configuration / sub-configuration. The CSI-RS ID can be sorted in sequence, and the order of each bit in the bitmap is consistent with the order of the corresponding CSI-RS. For example, for each test result that can be reported, a bitmap with a length equal to the length of the CSI-RS is configured, corresponding to the corresponding CSI-RS ID from the highest bit to the lowest bit. For each bit set to 1, it means that the CSI of the corresponding CSI-RS can be reported jointly, and if it is 0, it means that the CSI of the corresponding CSI-RS still needs to be reported separately.

[0064] For example, the base station configures 3 CSI-RS resources with a port number of 16 for the terminal. In the CSI reporting configuration, these 3 CSI-RS resources can be attributed to the same sub-configuration. For the 3 CSI-RS in the sub-configuration, the CSI of CSI-RS#1 and #2 can be reported jointly, and the CSI of CSI-RS#3 can be reported independently, then the third indication information can be configured as "110".

[0065] For another example, the third indication information is configured in a list format, where the list includes the IDs of the CSI-RSs corresponding to the CSIs that can be jointly reported.

[0066] A list is used to indicate the CSI-RS IDs that can be jointly reported for each test result to be reported. For CSI-RS not included in the list, its CSI measurement result is reported separately.

[0067] In some embodiments, a group report ID may be configured for each CSI-RS. For example, the third indication information includes a group report ID corresponding to each CSI-RS, and the CSI of CSI-RS with the same group report ID can be jointly reported.

[0068] The third indication information may be configured separately, or may be configured together with the first indication information, or may be configured together with the second indication information. That is, the CSI reporting configuration information may include one or more of the first indication information, the second indication information, and the third indication information.

[0069] For example, when the third indication information is configured separately, the third indication information may be used by default to indicate that measurement results of all measurement information of CSI-RSs corresponding to the CSI that can be jointly reported are jointly reported.

[0070] For example, when the third indication information and the first indication information are configured together, the third indication information is used for the CSI-RS corresponding to the CSI that can be jointly reported, and the first indication information is used to indicate whether the measurement result of each measurement information of the CSI-RS corresponding to the CSI that can be jointly reported is reported jointly.

[0071] For example, when the third indication information and the second indication information are configured together, the third indication information is used for the CSI-RS corresponding to the CSI that can be jointly reported, and the second indication information is used to indicate whether the CSI of the CSI-RS corresponding to the CSI that can be jointly reported is jointly reported.

[0072] For example, when the third indication information, the second indication information and the first indication information are configured together, the third indication information is used for the CSI-RS corresponding to the CSI that can be jointly reported, the second indication information is used to indicate whether the CSI of the CSI-RS corresponding to the CSI that can be jointly reported is jointly reported, and the first indication information is used to indicate whether the measurement result of each measurement information of the CSI-RS corresponding to the CSI that can be jointly reported is jointly reported.

[0073] In some embodiments, when the CSI-RS configured for the terminal is a semi-persistent or aperiodic CSI-RS, the base station may further send fourth indication information to the terminal to indicate whether the terminal reports according to the CSI reporting configuration information. The fourth configuration information may be carried by DCI (Downlink Control Information, downlink control information) / MAC (Media Access Control, media access control) CE (Control Element, control element).

[0074] For semi-persistent and non-periodic CSI-RS, if the first indication information is configured, when it is activated by DCI / MAC CE, an additional 1-bit 'GroupReportAct' field switch can be added to indicate whether to perform joint reporting or independent reporting according to the CSI reporting configuration information. If it is 1, it will be reported according to the configuration parameters in the CSI reporting configuration, and if it is 0, each measurement result will still be reported independently.

[0075] For example, the base station configures three CSI-RS resources with a port number of 16 for the terminal. In the CSI reporting configuration, these three CSI-RS resources can be attributed to the same sub-configuration. In the CSI reporting configuration, when ReportQuantity is configured as 'cri-RI-PMI-CQI', if ShareReportFlag is configured to 1, the terminal can use joint reporting of CSI measurement results at this time; further configure ReportFormat = '1111', which means that the measurement results of each measurement information are jointly reported. Further configure ReportGroup = '110', then in the final CSI report, the CSI of CSI-RS#1 and #2 are reported jointly, and the CSI of CSI-RS#3 is reported separately.

[0076] Since it is semi-persistent CSI, 1-bit GroupReportAct=1 may be configured in the activation DCI to activate the configuration in this CSI reporting configuration information.

[0077] In step S104, the terminal reports measurement results of multiple CSI-RSs to the base station according to the CSI reporting configuration information. Correspondingly, the base station receives measurement results of multiple CSI-RSs reported by the terminal according to the CSI reporting configuration information.

[0078] In the above embodiment, the base station sends CSI reporting configuration information to the terminal, including first indication information for indicating whether the measurement results of each measurement information of multiple CSI-RS are reported jointly. The present disclosure introduces a joint reporting mechanism, and the base station can instruct the terminal to use a joint reporting method for the measurement results of each measurement information of multiple CSI-RS, so that the measurement results of multiple CSI-RS can be reported jointly using a shared value, and it is no longer necessary to report the measurement results of each measurement information of each CSI-RS separately, which reduces the overhead caused by reporting the measurement results of multiple CSI-RS when reporting CSI and reduces resource consumption. Thereby promoting the practical application of network energy-saving technology based on multi-CSI feedback.

[0084] In some embodiments, the first indication information is configured in a bitmap manner, and the length of the bitmap is determined by the number of items of measurement information in the reporting quantity information element.

[0085] In some embodiments, each bit in the bitmap of the first indication information corresponds one-to-one to each item of measurement information in the reporting quantity information element.
