Description

Technical Field

[0001] The present invention relates to the field of communications, and in particular to a CSI reporting method and device, a storage medium, a terminal, and a network device. Background Art

[0002] In the 3rd Generation Partnership Project (3GPP) protocol, only the measurement and reporting of the channel state information (CSI) of the serving cell is currently supported, and different CSI reports have different priorities. When multiple CSI reports need to start occupying the CSI calculation resources of the user equipment (UE) at the same time, when the CSI calculation resources cannot meet the calculation requirements of the multiple CSI reports, the CSI report with a high priority is calculated first, and whether the CSI report with a low priority is calculated depends on the size of the remaining CSI calculation resources.

[0003] In the standardization stage of the New Radio (NR) protocol of version 17 (Rel-17) of the 3GPP protocol (Rel-17 corresponds to a protocol version of the NR protocol), in order to support fast cell switching of terminals and uplink and downlink data communication between terminals and non-serving cells, it is necessary to support the measurement and reporting of CSI for non-serving cells.

[0037] In the prior art, the priority of CSI reports for non-service cells is not defined. When the CSI reports for non-service cells and the CSI reports for service cells need to occupy CSI calculation resources or the time-frequency resources required for reporting overlap in the time domain, it is impossible to determine which CSI reports are not calculated or reported, which may affect the stability of wireless communication.

[0038] Specifically, during the NR protocol standardization phase of Rel-17, on one carrier, there may be both CSI reports for serving cells and CSI reports for non-serving cells. When the CSI reports for non-serving cells and the CSI reports for serving cells need to occupy CSI calculation resources or report the required time-frequency resources at the same time and overlap in the time domain, a new CSI report priority needs to be defined, and which CSI reports are not calculated or reported are determined according to the new CSI report priority.

[0039] In addition, on a carrier in the existing protocol, when multiple time-frequency resources required for sending CSI reports overlap in the time domain, a high-priority CSI report is sent first, and the priority of the CSI report is determined according to the time-domain periodicity of the multiple CSI reports and the type of the bearer channel. If the multiple CSI reports have different time-domain periodicities and bearer channel types, the low-priority CSI report is not reported; otherwise, the low-priority CSI report is multiplexed with the high-priority CSI report in the same time-frequency resource for reporting.

[0040] The priority of the CSI report of the serving cell can be expressed by the following formula: iCSI (y,k,c,s)=2·N cells ·M s y+N cells ·M s ·k+M s ·c+s; among them, Pri iCSI (y, k, c, s) is the priority (Pri) value of the i-th CSI report; N cells Indicates the maximum number of service cells supported for configuration; M sIndicates the maximum number of CSI reports supported for configuration; y=0,1,2,3. When y=0, it indicates that the type of bearer channel for CSI report and the time domain periodicity of reporting are Physical Uplink Shared Channel (PUSCH) bearer and aperiodic respectively; when y=1, it indicates that the type of bearer channel for CSI report and the time domain periodicity are PUSCH bearer and semi-persistent (SP) respectively; when y=2, it indicates that the type of bearer channel for CSI report and the time domain periodicity are Physical Uplink Control Channel (PUCCH) bearer and semi-persistent respectively; when y=3, it indicates that the type of bearer channel for CSI report and the time domain periodicity are PUCCH bearer and periodic respectively. k=0,1. Among them, k=0 means that the content of the CSI report includes the reference signal receiving power (RSRP) and / or the signal to interference plus noise ratio (SINR); k=1 means that the content of the CSI report includes the channel quality indication (CQI), rank indication (RI), and precoding matrix indication (PMI). c represents the identification (ID) of the serving cell where the reference signal corresponding to the CSI report is located; s represents the identification (ID) or index value (index) of the CSI report. The smaller the value of the priority of the CSI report, the higher the corresponding priority.

[0041] See also Figure 1 , Figure 1 This is a schematic diagram of a CSI report priority of a serving cell in the prior art; wherein, along the Y-axis direction, various parameters for determining the priority of the CSI report of the serving cell are represented. When the CSI report is carried by PUSCH and is non-periodic (i.e., corresponding to y=0), the value of k can be determined according to the content of the CSI report (RSRP or SINR or CQI, RI or PMI), and then the serving cell identifier (the identifier can be 0, 1, ...n, n is a positive integer) is obtained to determine the value of c, and the CSI report ID (the ID can be 0, 1, ...m, m is a positive integer) is obtained to determine the value of s. When y=1, 2, 3, the values ​​of the various parameters in the formula can also be determined according to the aforementioned method. The priority corresponding to each parameter changes from high to low along the X-axis direction.

[0042] See also Figure 2 , an embodiment of the present invention provides a CSI reporting method, Figure 2 The method may be executed by a terminal, such as a UE, and the method includes steps S201 to S203, which are described in detail as follows.

[0043] Step S201: upon receiving a configuration for calculating and reporting CSI reports of multiple cells, determining a priority of the CSI reports, wherein the multiple cells include at least one non-serving cell.

[0044] In this embodiment, a network device (including a base station (such as a gNB, eNB, etc.) or an access point (AP for short) can configure the UE so that the UE calculates and reports multiple CSI reports including non-serving cells. Optionally, the network device sends the configuration to the UE via Radio Resource Control (RRC) signaling.

[0045] Optionally, the multiple cells may include multiple non-service cells, and the multiple cells may also include one or more service cells and one or more non-service cells. Among them, for a connected user, a cell with which a communication connection is established or a cell with which data communication is performed is called a service cell, and a cell with which a communication connection is not established or a cell with which data communication is not performed is called a non-service cell.

[0046] Step S202: Calculate the CSI reports of the multiple cells according to the priorities of the CSI reports.

[0047] Step S203: reporting the CSI reports of the multiple cells according to the priorities of the CSI reports.

[0048] The UE calculates and reports the CSI reports of the multiple cells to the network device according to the configuration of the network device. When the UE calculates and reports the CSI reports of the multiple cells, the order or importance of calculation and reporting can be determined according to the priorities of the CSI reports.

[0049] Optionally, the step S202 of calculating the CSI reports of the multiple cells according to the priority of the CSI reports includes: when the CSI reports of the multiple cells need to occupy CSI calculation resources at the same time, preferentially calculating high-priority CSI reports according to the size of the CSI calculation resources.

[0050] Further, when the CSI reports of the multiple cells need to occupy CSI calculation resources at the same time, if the local CSI calculation resources of the UE are insufficient to calculate the CSI reports of the multiple cells at the same time, the CSI reports with higher priorities may be calculated first, and the calculated CSI reports may be reported to the network device first. Alternatively, the CSI reports of one or more cells with the lowest priority among the CSI reports of the multiple cells may not be calculated.

[0051] Optionally, step S203 of reporting the CSI reports of the multiple cells according to the priority of the CSI reports includes: on a single carrier, when the time-frequency resources occupied by the CSI reports of the multiple cells overlap in the time domain, preferentially reporting the CSI reports with higher priorities.

[0052] Furthermore, on a single carrier, when the time-frequency resources occupied by the CSI reports of the multiple cells overlap in the time domain, the CSI reports with higher priorities may be reported to the network device first, or the CSI reports of one or more cells with the lowest priority among the CSI reports of the multiple cells may not be reported.

[0053] pass Figure 1 The method described above enables the terminal and the base station to have consistent understanding of the calculation and reporting of the CSI report when the CSI report for the non-serving cell and the CSI report for the serving cell need to occupy CSI calculation resources or the time-frequency resources required for reporting overlap in the time domain, thereby ensuring the stability of wireless communication.

[0054] In one embodiment, Figure 2Determining the priority of the CSI report in step S201 includes: determining the priority of the CSI report according to at least one of rule one, rule two, rule three, rule four and rule five; wherein, rule one includes: the priority of the CSI report whose bearer channel type is PUSCH and whose time domain periodicity is non-periodic>the priority of the CSI report whose bearer channel type is PUSCH and whose time domain periodicity is semi-continuous>the priority of the CSI report whose bearer channel type is PUCCH and whose time domain periodicity is semi-continuous>the priority of the CSI report whose bearer channel type is PUCCH and whose time domain periodicity is periodic; Rule 2 includes: the priority of the CSI report including RSRP and / or SINR>the priority of the CSI report including at least one of CQI, RI, PMI; the rule 3 includes: the priority of the CSI report of the non-service cell is higher / lower than the priority of the CSI report of the serving cell; the rule 4 includes: determining the priority of the CSI report of the serving cell according to the index of the serving cell, and determining the priority of the CSI report of the non-service cell according to the physical layer cell index of the non-service cell; the rule 5 includes: determining the priority of the CSI report according to the index value of the CSI report.

[0055] Among them, the type of the bearer channel is the channel type of the CSI report that carries the report, and the channel type includes PUSCH and PUCCH. The time domain periodicity of the resource (Resource) of the time domain periodic Channel State Information Reference Signal (CSI-RI), the time domain periodicity includes periodic, non-periodic and semi-continuous. The type and time domain periodicity of the bearer channel of the non-service cell can refer to the relevant explanation of the type and time domain periodicity of the bearer channel of the service cell in the existing protocol, and this application will not repeat it.

[0056] The index of the serving cell may be a cell identifier (Cell Identifier, CID for short) of the serving cell, or may be determined according to a cell global identifier (Cell Global Identifier, CGI for short).

[0057] Optionally, the smaller the index of the serving cell, the higher the priority of the CSI report of the serving cell.

[0058] Optionally, the physical layer cell index of the non-serving cell is also called the physical cell identity (PCI). The smaller the PCI of the non-serving cell is, the higher the priority of its CSI report is.

[0059] Optionally, the smaller the index value of the CSI report, the higher the priority of the CSI report. That is, the network side may encode the index value of the CSI report and inform the UE so that the two have the same understanding of the index value of the CSI report.

[0060] It should be noted that the relationship between the index of the serving cell, the physical cell identifier of the non-serving cell, and the index value of the CSI report and the priority of the CSI report includes but is not limited to the above examples.

[0061] Optionally, determining the priority of the CSI report according to at least one of Rule 1, Rule 2, Rule 3, Rule 4 and Rule 5 includes: selecting rules in sequence according to the priority order of the rules to determine the priority of the CSI report.

[0062] Optionally, the priority order of the rules from high to low includes: Rule 1, Rule 2, Rule 3, Rule 4, Rule 5, or Rule 1, Rule 3, Rule 2, Rule 4, Rule 5, or Rule 3, Rule 1, Rule 2, Rule 4, Rule 5.

[0063] That is, the priority order of the rules includes: Rule 1>Rule 2>Rule 3>Rule 4>Rule 5; or, Rule 1>Rule 3>Rule 2>Rule 4>Rule 5; or, Rule 3>Rule 1>Rule 2>Rule 4>Rule 5.

[0064] In this embodiment, by defining the priority of CSI reports of non-service cells and serving cells, the UE can determine the priority of CSI reports of multiple cells. When the CSI report for the non-service cell and the CSI report for the serving cell need to occupy CSI calculation resources at the same time or the time-frequency resources required for reporting overlap in the time domain, the terminal and the base station maintain a consistent understanding of the calculation and reporting of the CSI report, thereby ensuring the stability of wireless communication.

[0065] See also Figure 3 The embodiment of the present invention also provides another CSI reporting method, which is executed by the network device side and includes:

[0067] Step S302, determining the priority of the CSI report;

[0068] Step S303: receiving the CSI report reported by the terminal according to the priority of the CSI report.

[0069] If the network device sends the configuration to the terminal, the network device also needs to determine the priorities of the CSI reports of multiple cells according to the method corresponding to the terminal side to determine which cells' CSI reports the terminal reports, so as to accurately receive these CSI reports.

[0070] Optionally, the CSI report reported by the terminal includes: when the CSI reports of the multiple cells need to occupy CSI calculation resources at the same time, the terminal preferentially calculates a high-priority CSI report according to the size of the CSI calculation resources.

[0073] Optionally, the smaller the index of the serving cell, the higher the priority of the CSI report of the serving cell.
