Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of communication, and particularly relates to a CSI reporting method and device, a terminal, a network device and a storage medium. BACKGROUND

[0002] In the 3rd Generation Partnership Project (3GPP) protocol, only reporting of channel state information (CSI) based on reference signal measurement is currently supported, and different CSI reports have different priorities. When multiple time-frequency resources required for sending CSI reports overlap in the time domain on one carrier, according to the time-domain periodicity of the multiple CSI reports and the type of the carried channel, the CSI report with high priority is preferentially sent. If the multiple CSI reports have different time-domain periodicity and the type of the carried channel, the CSI report with low priority is not reported; otherwise, the CSI report with low priority and the CSI report with high priority are multiplexed into the same time-frequency resource for reporting.

[0003] In the New Radio (NR) protocol standardization stage of the 17th version (Rel-17) of the 3GPP protocol (Rel-17 corresponds to a protocol version of the NR protocol), in order to support the base station to quickly obtain the channel state change, reporting of CSI based on physical downlink shared channel (PDSCH) decoding needs to be supported.

[0004] However, the prior art does not define the priority of the CSI report based on PDSCH decoding, so when the time-frequency resources required for reporting the multiple CSI reports including at least one CSI report based on PDSCH decoding overlap in the time domain, it is impossible to determine which CSI reports are not reported, which may affect the stability of wireless communication. SUMMARY

[0044] In order to make the technical solutions in the embodiments of the present application clearer, the accompanying drawings needed to be used in the embodiments or prior art description will be briefly introduced. Obviously, the accompanying drawings in the following description are only some embodiments of the present application, and other accompanying drawings can be obtained by those skilled in the art without any creative effort on the basis of these accompanying drawings.

[0045] The terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned accompanying drawings are used to distinguish different objects, and are not used to describe a specific order. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, software, product or device including a series of steps or units is not limited to the listed steps or units, but can optionally include steps or units not listed or can optionally include other steps or units inherent to the process, method, product or device.

[0046] Reference to“an embodiment” herein means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment. The appearances of the phrase“in one embodiment” in various places in the specification are not necessarily referring to the same embodiment, nor are they necessarily all directed to the same embodiment, nor are they necessarily all directed to a single embodiment.

[0047] In one carrier in the existing protocol, when multiple time-frequency resources required for sending CSI reports overlap in the time domain, high-priority CSI reports are preferentially sent, and the priority of the CSI reports is determined according to the time-domain periodicity of the multiple CSI reports and the type of the channel carrying the CSI reports. If the multiple CSI reports have different time-domain periodicities and types of the channel carrying the CSI reports, low-priority CSI reports are not reported; otherwise, low-priority CSI reports are multiplexed into the same time-frequency resource as high-priority CSI reports for reporting.

[0048] The priority of the CSI report of the serving cell can be represented by the following formula: Pri iCSI (y, k, c, s) = 2 · N cells · M s · y + N cells · M s · k + M s · c + s; wherein Pri iCSI (y, k, c, s) is the priority (Priority, referred to as Pri) value of the i th CSI report; N cells represents the maximum number of supported configured serving cells; M srepresents the maximum number of CSI reports supported by the configuration; y = 0, 1, 2, 3. Wherein, when y = 0, it represents that the type of the bearing channel of the CSI report and the reported time domain periodicity are physical uplink shared channel (PUSCH) bearing and aperiodic respectively; when y = 1, it represents that the type of the bearing channel of the CSI report and the time domain periodicity are PUSCH channel bearing and semi-persistent (SP) respectively; when y = 2, it represents that the type of the bearing channel of the CSI report and the time domain periodicity are physical uplink control channel (PUCCH) bearing and semi-persistent respectively; when y = 3, it represents that the type of the bearing channel of the CSI report and the time domain periodicity are PUCCH channel bearing and periodic. k = 0, 1. Wherein, k = 0 represents that the content of the CSI report includes reference signal receiving power (RSRP) and / or signal to interference plus noise ratio (SINR); k = 1 represents that the content of the CSI report includes channel quality indication (CQI), rank indication (RI), and precoding matrix indicator (PMI). c represents the service cell identification (ID) where the reference signal corresponding to the CSI report is located; s represents the report identification (ID) of the CSI report. The smaller the value of the priority of the CSI report is, the higher the corresponding priority is.

[0049] Please refer to Figure 1 , Figure 1 is a schematic diagram of the CSI report priority in the prior art; wherein, along the Y axis direction, each parameter for determining the priority of the CSI report of the service cell is represented, when the CSI report is borne by the PUSCH, aperiodic (that is, 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), then the value of c is determined by obtaining the service cell identification (the identification can be 0, 1, … n, n is a positive integer), and the value of s is determined by obtaining the CSI report ID (the ID can be 0, 1, … m, m is a positive integer). When y = 1, 2, 3, the values of each parameter in the formula can also be determined according to the foregoing method. The priority corresponding to each parameter changes from high to low along the X axis direction.

[0050] In the New Radio (NR) protocol standardization phase of the 17th version (Rel-17) of the 3GPP protocol (Rel-17 corresponds to a protocol version of the NR protocol), in order to support the base station to quickly obtain the channel state change, it is necessary to support the reporting of CSI based on PDSCH decoding. Considering introducing PDSCH decoding based CSI information feedback, the feedback parameter is denoted as deltaX. Specifically, the CSI report can contain one or more of CQI, SINR or MCS. Therefore, on one carrier, there can be both CSI reports based on reference signal measurement and CSI reports based on PDSCH decoding.

[0051] Currently, the prior art does not define the priority of the PDSCH decoding based CSI report, so when the time-frequency resources required by multiple CSI reports including at least one PDSCH decoding based CSI report overlap in the time domain, it is not determined which CSI reports are not reported, which can affect the stability of wireless communication.

[0052] Based on the above problems, the embodiment of the present application provides a CSI reporting method, which is described in detail as follows.

[0053] The embodiments of the present application are described in combination with terminals and network devices. The following is a specific introduction.

[0054] Specifically, the terminal in the embodiment of the present application can be a user equipment (UE), an access terminal, a user unit, a user station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a user terminal, a smart terminal, a wireless communication device, a user agent or a user device. The terminal can also be a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a relay device, a vehicle-mounted device, a wearable device, a terminal in a next-generation communication system such as an NR network, or a terminal in a future evolved public land mobile network (PLMN), etc., which is not limited specifically.

[0055] Further, the terminal can be deployed on land, including indoor or outdoor, handheld, wearable or vehicle-mounted; can be deployed on the water surface (such as ships, etc.); and can also be deployed in the air (such as airplanes, balloons and satellites, etc.).

[0056] Further, the terminal can be a mobile phone, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a vehicle-mounted device in self driving, a wireless terminal device in remote medical, a wireless terminal device in smart grid, a wireless terminal device in transportation safety, a wireless terminal device in smart city, or a wireless terminal device in smart home, etc.

[0057] Specifically, the network device in the embodiments of the present application can be a base transceiver station (BTS) in a global system of mobile communication (GSM) communication system or a code division multiple access (CDMA) communication system, a base station (nodeB, NB) in a wideband code division multiple access (WCDMA) communication system, an evolved node B (eNB or eNodeB) in a long term evolution (LTE) communication system, or a base station (gNB) in a new radio (NR) communication system. The network device can also be an access point (AP) in a wireless local area network (WLAN), a relay station, a network device in a future evolved PLMN network, or a network device in an NTN communication system, etc.

[0058] In combination with the above description, please refer to Figure 2 , Figure 2 A CSI reporting method provided by the embodiments of the present application is shown in Figure 2 , which includes steps S201 to S203, and the details are as follows.

[0059] S201, a terminal receives first configuration information, the first configuration information is used to configure a plurality of channel state information (CSI) reports, and the plurality of CSI reports include at least one CSI report based on physical downlink shared channel (PDSCH) decoding.

[0060] The implementation manner of the terminal receiving the first configuration information can be that the terminal receives the first configuration information from the network device.

[0061] Specifically, the first configuration information can be configured by at least one of radio resource control (RRC) dedicated signaling, a medium access control control element (MAC CE), and system broadcast information.

[0062] It should be noted that the embodiments of the present application consider that the network device sends the first configuration information to the terminal by at least one of RRC dedicated signaling, a MAC CE, and system broadcast information, so as to realize that when time-frequency resources required for reporting a plurality of CSI reports including PDSCH decoding-based CSI reports overlap in the time domain, the understanding of the terminal and the network device in terms of CSI report reporting is consistent, and the stability of wireless communication is ensured.

[0063] Further, the system broadcast information can include system information block (SIB) information.

[0064] S202, the terminal determines priorities of the plurality of CSI reports.

[0065] The plurality of CSI reports are CSI reports of a serving cell. The serving cell refers to a cell that establishes a communication connection with a connected state user or a cell that performs data communication.

[0066] S203, the terminal sends part or all of the plurality of CSI reports according to the priorities of the plurality of CSI reports.

[0067] The implementation manner of the terminal sending part or all of the plurality of CSI reports according to the priorities of the plurality of CSI reports can be that the terminal sends part or all of the plurality of CSI reports to the network device according to the priorities of the plurality of CSI reports.

[0068] It can be seen that the terminal reports the plurality of CSI reports to the network device according to the configuration of the network device. When the terminal reports the plurality of CSI reports, the order or importance information of the reporting can be determined according to the priorities of the CSI reports.

[0069] It can be seen that, in the embodiment of the present application, the terminal first receives the first configuration information, the first configuration information is used for configuring a plurality of channel state information (CSI) reports, the plurality of CSI reports include at least one CSI report based on physical downlink shared channel (PDSCH) decoding, then determines the priority of the plurality of CSI reports, and finally transmits part or all of the plurality of CSI reports according to the priority of the plurality of CSI reports. Compared with the prior art, by the method, when the required time-frequency resources for reporting the plurality of CSI reports including at least one CSI report based on PDSCH decoding overlap in the time domain, the terminal can report part or all of the plurality of CSI reports based on the priority of the plurality of CSI reports, and the reliability of wireless communication is ensured.

[0070] In combination with the above description, the first configuration information will be specifically introduced in the embodiments of the present application.

[0071] In one possible embodiment, the implementation manner of the step S203 that the terminal transmits part or all of the plurality of CSI reports according to the priority of the plurality of CSI reports can be that, on a single carrier, when the time-frequency resources occupied by the plurality of CSI reports overlap in the time domain, the terminal transmits part or all of the plurality of CSI reports according to the priority of the plurality of CSI reports.

[0072] Specifically, on a single carrier, when the time-frequency resources occupied by the plurality of CSI reports overlap in the time domain, the terminal can transmit at least one high-priority CSI report with a priority in the first n positions in the plurality of CSI reports according to the priority of the plurality of CSI reports, or can transmit at least one CSI report except for the CSI report with a priority in the last m positions in the plurality of CSI reports, and correspondingly, can not transmit the at least one CSI report with a priority in the last m positions in the plurality of CSI reports. m and n are not specifically limited, and m and n are positive integers. n or m is pre-set according to needs, and n or m is not specifically limited.

[0073] For example, when n is 1, that is, on a single carrier, when the time-frequency resources occupied by the plurality of CSI reports overlap in the time domain, the terminal can transmit the CSI report with the highest priority in the plurality of CSI reports according to the priority of the plurality of CSI reports.

[0074] For another example, when n is 3, that is, on a single carrier, when the time-frequency resources occupied by the plurality of CSI reports overlap in the time domain, the terminal can transmit the CSI report with a high priority in the first 3 positions in the plurality of CSI reports according to the priority of the plurality of CSI reports.

[0075] For example, when m is 1, i.e. on a single carrier, when the time-frequency resources occupied by the multiple CSI reports overlap in time domain, the terminal can send the CSI reports other than the CSI report with the lowest priority according to the priorities of the multiple CSI reports.

[0076] For another example, when m is 2, i.e. on a single carrier, when the time-frequency resources occupied by the multiple CSI reports overlap in time domain, the terminal can send the CSI reports other than the two CSI reports with the lowest priorities according to the priorities of the multiple CSI reports.

[0077] In a possible embodiment, the step S202 includes that the terminal determines the priority of the plurality of CSI reports according to the following rules: the priority of a first sub-rule is higher than the priority of a second sub-rule, the priority of the second sub-rule is higher than the priority of a third sub-rule, the priority of the third sub-rule is higher than the priority of a fourth sub-rule, the priority of the fourth sub-rule is higher than the priority of a fifth sub-rule; or, the priority of the first sub-rule is higher than the priority of a sixth sub-rule, the priority of the sixth sub-rule is higher than the priority of the fourth sub-rule, the priority of the fourth sub-rule is higher than the priority of the fifth sub-rule; or, the priority of the second sub-rule is higher than the priority of the first sub-rule, the priority of the first sub-rule is higher than the priority of the third sub-rule, the priority of the third sub-rule is higher than the priority of the fourth sub-rule, the priority of the fourth sub-rule is higher than the priority of the fifth sub-rule; wherein the first sub-rule includes that the priority of a CSI report with a channel type of a physical uplink shared channel (PUSCH) and a time domain periodicity of aperiodic is higher than the priority of a CSI report with the channel type of the PUSCH and a time domain periodicity of semi-persistent, the priority of the CSI report with the channel type of the PUSCH and the time domain periodicity of semi-persistent is higher than the priority of a CSI report with a channel type of a physical uplink control channel (PUCCH) and a time domain periodicity of semi-persistent, the priority of the CSI report with the channel type of the PUCCH and the time domain periodicity of semi-persistent is higher than the priority of a CSI report with the channel type of the PUCCH and a time domain periodicity of periodic; the second sub-rule includes that the priority of a CSI report with content of deltaX is higher than the priority of a CSI report with content of a reference signal received power (RSRP) and / or a signal to interference noise ratio (SINR), the deltaX being a feedback parameter of the PDSCH decoding based CSI information; the third sub-rule includes that the priority of a CSI report with content of the RSRP and / or the SINR is higher than the priority of a CSI report with content of at least one of a channel quality indicator (CQI), a rank indication (RI), and a precoding matrix indication (PMI); the fourth sub-rule includes that the priority of a CSI report with a cell index value of a cell where a signal or a channel is measured is smaller is higher than the priority of a CSI report with a cell index value of a cell where a signal or a channel is measured is larger; the fifth sub-rule includes that the priority of a CSI report with a report index value is smaller is higher than the priority of a CSI report with a report index value is larger; and the sixth sub-rule includes that the priority of a CSI report with content of the RSRP and / or the SINR is higher than the priority of a CSI report with content of the deltaX, the priority of the CSI report with content of the deltaX is higher than the priority of a CSI report with content of at least one of the CQI, the RI, and the PMI.

[0078] The bearer channel type is a channel type that carries the CSI report, and the channel type includes a PUSCH and a PUCCH. The time domain periodicity refers to a time domain periodicity of a resource of a time domain periodicity channel state information reference signal (CSI-RI), and the time domain periodicity includes periodicity, aperiodicity, and semi-persistent.

[0079] The deltaX can be a deltaCQI or a delta MCS (Modulation and Coding Scheme).

[0080] It should be noted that the CSI report including the deltaX is a PDSCH decoding-based CSI report, and the CSI report including at least one of the RSRP, the SINR, the CQI, the RI, and the PMI is a reference signal measurement-based CSI report.

[0081] The network device can pre-set and inform the terminal of the priority of the CSI report including one of the deltaX, the RSRP, the SINR, the CQI, the RI, and the PMI, so that the network device and the terminal have consistent understanding of the priority of the CSI report including the deltaX, the RSRP, the SINR, the CQI, the RI, and the PMI.

[0082] The cell index of the serving cell can be a cell identifier (CID) of the serving cell, or can be determined according to a cell global identifier (CGI).

[0083] In a specific implementation, the network device can pre-encode and inform the terminal of an index value of each CSI report in the plurality of CSI reports, so that the network device and the terminal have consistent understanding of the index value of the CSI report.

[0084] It should be noted that the cell index of the serving cell, the reporting index value of the CSI report, the bearer channel type, the time domain periodicity, and the high-low relationship of the content and the priority of the CSI report include but are not limited to the above examples.

[0085] Specifically, the implementation manner of the terminal determining the priority of the plurality of CSI reports can be that the terminal selects the sub-rules in a descending order of the priority of the sub-rules to determine the priority of the plurality of CSI reports.

[0086] Further, the terminal selects the sub-rules in order from high to low priority of the sub-rules to determine the priorities of the multiple CSI reports, including: the terminal determines the priorities of at least two first CSI reports according to the currently selected sub-rule, to obtain a target determination result, the at least two first CSI reports being CSI reports in the multiple CSI reports for which the priorities are not determined; if the target determination result includes at least two second CSI reports, the at least two second CSI reports being CSI reports in the at least two first CSI reports for which the priorities are not determined, then determining the priorities of the at least two second CSI reports according to a sub-rule of a next priority of the currently selected sub-rule.

[0087] In a specific implementation, the terminal selects the sub-rules in order from high to low priority of the sub-rules for the multiple CSI reports, and when the sub-rule of a higher priority cannot completely determine the priorities of all the CSI reports in the multiple CSI reports, determines the priorities of the CSI reports in the multiple CSI reports for which the priorities are not determined according to a sub-rule of a lower priority, until the priorities of all the CSI reports in the multiple CSI reports are determined.

[0088] In this embodiment, by defining the priorities of the CSI reports based on PDSCH decoding, the terminal can determine the priorities of the multiple CSI reports of the multiple serving cells including at least one CSI report based on PDSCH decoding, and when the required time-frequency resources for reporting the multiple CSI reports overlap in the time domain, the terminal and the network device can keep consistent understanding in terms of CSI report reporting, and the stability of wireless communication is ensured.

[0092] S303, the network device receives part or all of the multiple CSI reports according to the priorities of the multiple CSI reports.

[0093] In one possible example, the transmitting part or all of the multiple CSI reports according to the priority of the multiple CSI reports includes: on a single carrier, when time-frequency resources occupied by the multiple CSI reports overlap in time domain, transmitting part or all of the multiple CSI reports according to the priority of the multiple CSI reports.

[0094] In one possible example, the determining the priority of the plurality of CSI reports comprises determining the priority of the plurality of CSI reports according to the following rules: the priority of a first sub-rule is higher than the priority of a second sub-rule, the priority of the second sub-rule is higher than the priority of a third sub-rule, the priority of the third sub-rule is higher than the priority of a fourth sub-rule, the priority of the fourth sub-rule is higher than the priority of a fifth sub-rule; or, the priority of the first sub-rule is higher than the priority of a sixth sub-rule, the priority of the sixth sub-rule is higher than the priority of the fourth sub-rule, the priority of the fourth sub-rule is higher than the priority of the fifth sub-rule; or, the priority of the second sub-rule is higher than the priority of the first sub-rule, the priority of the first sub-rule is higher than the priority of the third sub-rule, the priority of the third sub-rule is higher than the priority of the fourth sub-rule, the priority of the fourth sub-rule is higher than the priority of the fifth sub-rule; wherein the first sub-rule comprises that the priority of a CSI report with a channel type of a physical uplink shared channel (PUSCH) and a time domain periodicity of aperiodic is higher than the priority of a CSI report with the channel type of the PUSCH and a time domain periodicity of semi-persistent, the priority of the CSI report with the channel type of the PUSCH and the time domain periodicity of semi-persistent is higher than the priority of a CSI report with a channel type of a physical uplink control channel (PUCCH) and a time domain periodicity of semi-persistent, the priority of the CSI report with the channel type of the PUCCH and the time domain periodicity of semi-persistent is higher than the priority of a CSI report with the channel type of the PUCCH and a time domain periodicity of periodic; the second sub-rule comprises that the priority of a CSI report with content of deltaX is higher than the priority of a CSI report with content of RSRP and / or SINR, the deltaX being a feedback parameter of the PDSCH decoding based CSI information; the third sub-rule comprises that the priority of the CSI report with the content of RSRP and / or SINR is higher than the priority of a CSI report with content of at least one of channel quality indicator (CQI), rank indicator (RI), and precoding matrix indicator (PMI); the fourth sub-rule comprises that the priority of a CSI report with a cell index value of a cell where a signal or a channel is measured is smaller is higher than the priority of a CSI report with a cell index value of a cell where a signal or a channel is measured is larger; the fifth sub-rule comprises that the priority of a CSI report with a report index value is smaller is higher than the priority of a CSI report with a report index value is larger; the sixth sub-rule comprises that the priority of the CSI report with the content of RSRP and / or SINR is higher than the priority of the CSI report with the content of deltaX, the priority of the CSI report with the content of deltaX is higher than the priority of the CSI report with the content of at least one of CQI, RI, and PMI.
