Description

Technical Field

[0001] The present invention relates to the technical field of communications.

Background Art

[0002] In a New Radio (NR) system, a user measures the current channel based on channel state information (CSI) resource settings and CSI report settings set on the network device side, and uses uplink control information (UCI) in the uplink channel (for example, Physical Uplink Control Channel PUCCH, Physical Uplink Shared Channel PUSCH) to carry the channel state information and perform feedback of the report.

[0003] The multi-transmission reception point (M-TRP) cooperative transmission scheme is an important technology for improving the throughput of cell-edge users in the NR system and providing a more balanced service quality for the serving cell. The M-TRP transmission scheme can be broadly classified into two types, namely, the coherent joint transmission (C-JT) scheme and the non-coherent joint transmission (NC-JT) scheme. The specific implementation difference between the two lies in the different mapping relationships from the layer to multiple TRPs. In the C-JT scheme, all Physical Downlink Shared Channel / Demodulation Reference Signal (PDSCH / DMRS) ports jointly transmitted from multiple transmission reception points (TRPs) perform coherent transmission with signals from multiple TRPs. In the NC-JT scheme, the PDSCH / DMRS ports are transmitted from each TRP respectively.

[0004] FIG. 1 is a diagram showing single-point transmission, coherent joint transmission, and non-coherent joint transmission. A in FIG. 1 corresponds to single-point transmission, B in FIG. 1 corresponds to C-JT transmission, and C in FIG. 1 corresponds to NC-JT.

[0005] In Rel-15 / 16, all users report CSI based on a single-transmission reception point (S-TRP) scheme, which includes precoding matrix indicators (PMI), rank indicators (RI), layer indicators (LI), channel quality indicators (CQI), etc. Rel-17 supports enhanced CSI resource configuration and reporting for the NC-JT scheme, allowing terminal equipment to perform joint channel measurements based on reference signals transmitted by M transmission points based on NC-JT transmission, and report M PMIs, M RIs, M LIs, N CQIs (N=1 for single codewords, N=2 for dual codewords), etc. Currently, only CSI reporting under the 'type I single-panel' codebook configuration is supported.

[0006] In coherent joint transmission, each data layer is mapped to multiple TRPs / panels participating in coordination by a weighted vector, and this scheme is equivalent to concatenating multiple submatrices to form a higher-dimensional virtual matrix. Therefore, the C-JT transmission scheme can achieve higher forming / precoding / multiplexing gains and significantly improve the throughput of cell edge users and the average throughput of the cell.

[0007] The above-mentioned introduction of background art is intended to clearly and completely explain the proposed technical aspects of the present invention and to make them easily understandable to those skilled in the art. These technical aspects, as described in the background art of the present invention, should not be construed as being well-known to those skilled in the art. [Overview of the project] [Problems that the invention aims to solve]

[0008] According to the data / reference signal transmission and mapping characteristics in the CJT transmission scheme, terminal equipment must perform joint channel measurements based on reference signals transmitted by K multi-transmission points based on C-JT transmission, and also need to provide joint feedback of single CSI information such as PMI, RI, LI, and CQI.

[0009] However, currently, the CSI feedback mechanism in the Rel-15 to Rel-17 standards cannot be applied to CSI feedback in the C-JT transmission scheme. In other words, the CSI feedback from terminal equipment cannot accurately and completely reflect the real channel quality traversed by the C-JT resource port, which reduces the accuracy and reliability of data scheduling. This can lead to decreased data transmission performance and reduced throughput for both single users and the entire network.

[0010] For example, in conventional technology, information such as part II reporting field information and bit width in the CSI reporting field under CJT joint transmission is not defined, and therefore, network equipment cannot accurately receive and demodulate part II information based on the joint coherent transmission scheme. Also, for example, when terminal equipment receives all part I information based on the joint coherent transmission scheme, the reporting priority (priority) of part I information is not defined, so when the code rate is higher than a predetermined maximum code rate, network equipment cannot determine omit information based on the priority definition, and as a result, it is not possible to accurately receive and demodulate some of the CSI information, which greatly affects the accuracy and completeness of measurement reports and makes it impossible to guarantee data transmission performance.

[0011] In view of at least one of the above-mentioned problems or other similar problems, embodiments of the present invention provide a method and apparatus for transmitting and receiving channel state information and a communication system, wherein the set information of the reporting area information of channel state information part II (CSI part II) is determined based on M CSIRS resources relating to K CSIRS resources, and the CSI reporting priority is determined based on the set information, thereby enabling network equipment to accurately receive and demodulate the CSI it receives, thereby improving the accuracy and completeness of measurement reports and ensuring data transmission performance. [Means for solving the problem]

[0012] According to one aspect of the embodiment of the present invention, a channel state information transmitting device is provided, which is applied to terminal equipment, and the device is A first receiver that receives a first channel status information reference signal (CSIRS) resource setting transmitted by a network device, wherein the first CSIRS resource setting includes at least a first resource set, and the first resource set has K CSIRS resources, where K is a natural number of 2 or more; and A first processor that determines the CSI reporting priority based on a set of reporting domain information of at least part II of the channel state information (CSI part II), wherein the set of reporting information is determined based on M CSIRS resources relating to the K CSIRS resources, where M is a natural number less than or equal to K, and the first processor generates CSIs based at least on the CSI reporting priority.

[0013] According to another aspect of the embodiments of the present invention, a channel state information receiving device is provided, which is applied to network equipment, and the device is A second transmitter that transmits a first channel status information reference signal (CSIRS) resource setting to a terminal device, wherein the first CSIRS resource setting includes at least a first resource set, and the first resource set has K CSIRS resources, where K is a natural number greater than or equal to 2; and The terminal device includes a second receiver that receives CSIs generated based on CSI reporting priority, Of these, the CSI reporting priority is determined based on a set of reporting domain information of at least part II of the channel status information (CSI part II), and the set of reporting domain information is determined based on M CSIRS resources relating to the K CSIRS resources, where M is a natural number less than or equal to K. [Effects of the Invention]

[0014] The advantageous effects of the embodiment of the present invention are at least as follows: the set information of the reporting area information of channel state information part II (CSI part II) is determined based on M CSIRS resources relating to K CSIRS resources, and the CSI reporting priority is determined based on this set information. As a result, network equipment can accurately receive and demodulate the CSI it receives, thereby improving the accuracy and completeness of measurement reports and ensuring data transmission performance.

[0030] The following describes a scenario of an embodiment of the present invention through examples, but the present invention is not limited thereto.

[0031] Figure 2 shows a communication system in an embodiment of the present invention, illustrating an example with terminal equipment and network equipment. As shown in Figure 2, the communication system 100 may include network equipment 201 and terminal equipment 202. For convenience, Figure 1 uses only one terminal device as an example, but embodiments of the present invention are not limited to this.

[0032] In embodiments of the present invention, existing business (traffic / services) or future business that can be implemented may be transmitted and received between the network device 201 and the terminal device 202. For example, these business operations may include, but are not limited to, eMBB (enhanced Mobile Broadband), mMTC (massive Machine Type Communication), URLLC (Ultra-Reliable and Low-Latency Communication), etc.

[0033] Among these, terminal device 202 may transmit data to network device 201, and may employ, for example, an authorized (licensed) or unauthorized (unlicensed) transmission method. Network device 201 may receive data transmitted by one or more terminal devices 202 and provide feedback to terminal device 202, such as acknowledgment (ACK) / non-acknowledgment (NACK) information, and terminal device 202 may, based on the feedback information, confirm the completion of the transmission process, or perform a new data transmission again, or retransmit the data.

[0034] In each embodiment of the present invention, "reporting" may refer to the act (operation) of a terminal device transmitting information to a network device. For example, "a terminal device reporting a CSI" may refer to the terminal device transmitting a CSI to a network device.

[0035] Figure 3 illustrates how the NR system performs decoupling based on CSI measurement and CSI feedback. As shown in Figure 3, each terminal device can configure N (N≧1) reporting settings and M (M≧1) resource settings. Each reporting setting is associated with at least one resource setting and is used for channel measurement and interference measurement. For each bandwidth portion (BWP), N≦12 and M≦28.

[0036] CSI resource settings are used for interference measurement (CSI-IM / NZP CSI-RS) and CSI acquisition (NZP CSI-RS). Each resource setting contains S resource sets. Each resource set contains Ks CSI-RS resources.

[0037] The CSI reporting method is set as one of AP, P, and SP. Of these, method AP may include one or more resource sets. Methods P and SP may include only one resource set when used for CSI acquisition.

[0038] The CSI reporting settings are used to configure the CSI parameters (report quantity), CSI type (Type I or Type II), codebook parameter settings, CSI reporting time domain actions, frequency domain granularity of precoding matrix indicators (PMI) and channel quality indicators (CQI), measurement constraint settings, and CSI reporting bandwidth.

[0039] The report quantity parameters supported by NR include 'none', 'cri-RI-PMI-CQI', 'cri-RI-i1', 'cri-RI-i1-CQI', 'cri-RI-CQI', 'cri-RSRP', 'cri-SINR', 'ssb-Index-RSRP', 'ssb-Index-SINR' or 'cri-RI-LI-PMI-CQI', etc.

[0040] CSI types include 'typeI Single-Panel', 'typeI Multi-Panel', 'typeII', 'typeII-PortSelection', 'typeII-r16', 'typeII-PortSelection-r16', 'typeII-PortSelection-r17', etc.

[0041] Furthermore, in CSI reports based on 'typeII-r16' and 'typeII-PortSelection-r17', only broadband parameter information can be reported via the physical uplink control channel (PUCCH), and if subband codebook parameter information exists, it can be reported only via the physical uplink sharing channel (PUSCH), which may be further divided into Part I and Part II. For example, as shown in Table 1 below.

[0042] [Table 1] In CSI reports based on 'typeII-r16', PMI W can be represented by W1, W2, and Wf.

[0043] The terminal device reports L spatial base vectors W1 and Mv frequency domain base vectors Wf, and must calculate a combined coefficient W2 based on the selected SD-FD, which consists of amplitude / phase coefficient. Therefore, Part II information can be divided into information fields X1 and X2. Specifically, these are as follows:

[0044] 1) Information fields X1: Includes SD selected beam and strongest coefficient indication (SCI); a) SD Selected Beams i1,1,i1,2: W1 is divided into N1N2O1O2 beams, all beams are first divided into (O1O2) sets of blocks, the terminal equipment first selects one best set of blocks i1,1, each set of blocks contains N1N2 beams, and then selects L best beams i1,2; b) Maximum non-zero coefficient indication i1,8,l: Based on the maximum number of non-zero coefficients K0 in the network device settings, the terminal needs to report the actual number of non-zero coefficients KNZ. For layer 1, the number is equal to the total actual number of non-zero coefficients KNZ. Therefore, the overhead of the maximum non-zero coefficient indication is

[0045]

number

[0046]

number

[0047] 2) Information fields X2: Includes FD base vector, amplitude / phase indicators, and bitmap indicator; a) Non-zero coefficient indicators i1,7,l (bitmap indicators): The non-zero coefficient indicators employ the most direct scheme, with each layer using a 2LM bit bitmap for the indicators; b) Mv base vectors are selected from the FD base vector indications i1, 5, i1, 6, l:N3, and a cyclic shift is performed on the frequency domain base vector so that the first frequency domain base vector becomes essential (corresponding to the strongest coefficient), and the remaining base vectors are obtained from N3-1 candidate base vectors. Therefore, the feedback overhead is,

[0048]

number

[0049] The bit widths of information fields X1 and X2 are as shown in Table 2 (Table 6.3.2.1.2-1A: PMI of codebookType=typeII-r16).

[0050] [Table 2] In CSI reports based on TIFF2026508843000158.tif45168'typeII-r16', Part II information is grouped into sets, such as G0, G1, and G2. The information included in each set is as follows:

[0051] G0 (Group 0): SD selected beams i1,1,i1,2, strongest coefficient indications i1,8, l (Information fields X1); G1 (Group 1): Base vector indicators i1, 5, i1, 6, l,

[0059] In CSI reporting based on 'typeII-r16', Part II information is grouped, and then reported according to the group priority. For example, starting from the lowest priority, CSI reports are omitted until the code rate of the CSI report is less than or equal to the code rate set by the higher-level parameter (the higher-level parameter is, for example, maxCodeRate). The group priorities are shown, for example, in Table 5.2.3-1: Priority reporting levels for Part 2 CSI.

[0060] [Table 3] In each of the following embodiments of the present invention, at least a portion of the CSI is ignored, which may also be referred to as omitting or dropping at least a portion of the CSI; in other words, ignored, omitted, and dropped are interchangeable, and any of these three terms can correspond to omit.

[0061] Furthermore, in the following embodiments of the present invention, the uppercase letter K has the same meaning as the lowercase letter k.

[0062] <Example of the first side view> In conventional technologies, for example, in the current Uplink Control Information (UCI) reporting based on 'typeII-r16' and 'typeII-PortSelection-r17', the part II reporting area information and bit width in the CSI reporting area under CJT joint transmission are not defined. Therefore, when network equipment receives part II information based on the joint coherent transmission scheme, it may not be able to receive and demodulate it accurately. Furthermore, when terminal equipment receives all part II information based on the joint coherent transmission scheme, if the reporting priority of part II information is not currently defined, and the code rate at that time exceeds the maximum code rate that can be set, the network equipment may not be able to ignore the information based on the defined priority. As a result, it may not be able to receive and demodulate some of the CSI information accurately, which significantly affects the accuracy and completeness of the measurement report and makes it impossible to guarantee data transmission performance.

[0063] To solve the above-mentioned problems or at least similar problems, a method for transmitting channel state information is provided in an embodiment of the first aspect of the present invention, which is applied to a terminal device. In the following description, the terminal device may be, for example, terminal device 302 in Figure 3, and the network device communicating with the terminal device may be, for example, network device 301 in Figure 3.

[0064] Figure 4 shows a method for transmitting channel state information in an embodiment of the first aspect of the present invention. As shown in Figure 4, the method includes the following, namely, Operation 401: A terminal device receives a first channel status information reference signal (CSIRS) resource setting transmitted by a network device, the first CSIRS resource setting includes at least a first resource set, the first resource set has K CSIRS resources, where K is a natural number greater than or equal to 2; Operation 402: The terminal device determines the CSI reporting priority based on a set of reporting area information of at least part II of the channel state information (CSI part II), the set of reporting information is determined based on M CSIRS resources relating to the K CSIRS resources, where M is a natural number less than or equal to K; and Operation 403: The terminal device generates a CSI based at least on the CSI reporting priority.

[0065] In this invention, since K CSIRS resources can correspond to K transmission points (TRPs) in a coherent joint transmission (C-JT) scheme, the channel status information transmission method of this invention can be applied to CSI reporting under a C-JT transmission scheme.

[0066] In some embodiments, the M CSIRS resources relate to the K CSIRS resources related to operation 401, for example, the M CSIRS resources are M of the K CSIRS resources.

[0067] The M CSIRS resources are the best (most superior) resources among the K CSIRS resources, and for example, the best resources include the following, namely, The first number of resources prior to the maximum reference signal receiving power (RSRP), where the first number is less than or equal to M; and / or RSRP is a second number of resources greater than or equal to a predetermined threshold, and the second number is less than or equal to M; and / or The third number of resources prior to the minimum block error rate (BLER), where the third number is M or less; and / or BLER is a fourth quantity of resources below a predetermined threshold, and the fourth quantity is M or less.

[0068] In operation 403, the terminal device generating a CSI based on at least the CSI reporting priority includes the terminal device omitting at least a portion of the CSI based on the CSI reporting priority. For example, when the code rate of a CSI report is greater than or equal to the code rate set by the layer parameter (e.g., the upper layer parameter is maxCodeRate), the terminal device may omit, ignore, or drop some CSI reports according to the CSI reporting priority (e.g., the reporting priority of CSI part I), starting from the lowest priority, until "code rate of CSI report ≤ code rate set by the number of upper layer parameters (e.g., the upper layer parameter is maxCodeRate)".

[0069] In operation 402 of the present invention, the terminal device determines the CSI reporting priority based on the set information of reporting area information of part II of the channel state information (CSI part II).

[0070] In some embodiments of operation 402, the M resource index value j may be sorted in the following order: Of the M resources, the first-order (j=1) CSIRS resource corresponds to the Strongest coefficient Indicator (SCI) in the Reported PMI (Precoding Matrix Indicator), and / or, the second to the Mth-order (j=2,3,4,…,M) CSIRS resources of the M resources may be sorted according to the strengths for determining the amplitude merge coefficient in the Reported PMI (Precoding Matrix Indicator), for example, the strengths for determining the amplitude merge coefficient in the Reported PMI.

[0071] In some embodiments of operation 402, the set information includes a first set (e.g., G0) of information, a second set (e.g., G1) of information, and a third set (e.g., G2) of information.

[0072] The aforementioned Group 1, Group 2, and Group 3 can be divided into multiple groups.

[0073] When the codebook type of channel state information part II (CSI part II) is set to mode 1, grouping method 1a can be adopted, and in grouping method 1a, The information in the first set (G0) includes the following, namely, Codebook parameters for determining the spatial domain beam selection result corresponding to each of the M CSIRS resources, wherein the parameters are i1, 1, j, i1, 2, j, of which j = 1, 2, ..., M; and / or The codebook parameters for determining the strongest coefficient selection result corresponding to the M CSIRS resources are i1, 8, l, of which l = 1, ..., υ, where υ is the number of transmission layers and relates to the rank indication in part I of the channel state information; The information for Group 2 (G1) includes the following, namely, Instruction information for determining the frequency domain base vector of each of the M CSIRS resources, the instruction information being, for example, i1,5,j,i1,6,l,j; and / or The preceding X1 high-priority non-zero coefficients i1,7,l,j are used to determine each of the M CSIRS resources; and / or Information for determining the reference merger coefficients i2, 3, l corresponding to the M CSIRS resources mentioned above. and / or The preceding Y1 high-priority codebook parameters i2,4,l,j are used to determine the difference amplitude merging coefficient of each CSIRS resource among the M CSIRS resources; and / or The preceding Z1 high-priority codebook parameters i2,5,l,j are used to determine the phase merge coefficient of each CSIRS resource among the M CSIRS resources; and / or i1,9,l,j-1 are frequency domain offset information relative to the strongest resource, used to determine each CSIRS resource among the M resources mentioned above. Of these, X1, Y1, and Z1 are all natural numbers; The third set of information includes the following, namely, X2 low-priority non-zero coefficients i1, 7, l, j for determining each of the M CSIRS resources; and / or The following Y2 low-priority codebook parameters i2,4,l,j are used to determine the difference amplitude merging coefficient of each CSIRS resource among the M CSIRS resources; and / or The following are two low-priority codebook parameters i2, 5, l, and j for determining the phase merger coefficient of each CSIRS resource among the M CSIRS resources: Of these, X2, Y2, and Z2 are all natural numbers.

[0074] In some examples, The value of X1 is determined based on a predetermined number of index values ​​that are sorted in order from low to high, and the first number is

[0106] In some embodiments, the bit widths of the Part II codebook parameters based on the CJT transmission scheme are as shown in Table 4.

[0107] [Table 4] In TIFF2026508843000190.tif60167 operation 402, the priority order can be determined based on the grouping method described above.

[0108] In several embodiments, a priority order 1 can be adopted for grouping methods 1a, 1b, 2a, and 2b, for example, G0 > G1 > G2, and in this priority order 1, The priority of the first set of information (G0) corresponding to each of the M CSIRS resources is higher than the priority of the second set of information corresponding to each of the M CSIRS resources; The priority of the second set of information corresponding to each of the M CSIRS resources is higher than the priority of the third set of information corresponding to each of the M CSIRS resources. In the first set of information, the priority of the information corresponding to each of the M CSIRS resources is determined based on the priority of each CSIRS resource; and / or In the second set of information, the priority of the information corresponding to each of the M CSIRS resources is determined based on the priority of each CSIRS resource; and / or In the third set of information, the priority of the information corresponding to each of the M CSIRS resources is determined based on the priority of each CSIRS resource.

[0109] In some embodiments, a priority order 2 can be adopted for the grouping method 3. For example, in this priority order 2, The priority for information on Group Zero (G0) is the highest; The priority of the first set of information (G10~GM0) and the second set of information (G11~GM1) corresponding to the (j+1)th resource among the M CSI-RS resources is higher than the priority of the first set of information (G10~GM0) and the second set of information (G11~GM1) corresponding to the (j-1)th resource, and among these, 1 ≤ j ≤ M; and The priority of the first set of information (G10~GM0) corresponding to the j-th resource is higher than the priority of the second set of information (G11~GM1).

[0110] For example, in priority order 2, the priority order of each pair from highest to lowest is as follows: G0>G10>G11>G20>G21>…>GM0>GM1 And among them, G0 represents the first set of information corresponding to each of the M CSIRS resources; G10, ..., GM0 represent the first set of information corresponding to each of the M CSIRS resources; and G11, ..., GM1 represent a second set of information corresponding to each of the M CSIRS resources.

[0111] In some embodiments, a priority order 3 can be adopted for the grouping method 4. For example, in this priority order 3, The priority for information on Group Zero (G0) is the highest; The priority of the first set of information (G10~GM0), the second set of information (G11~GM1), and the third set of information (G12~GM2) corresponding to the (j+1)th resource among the M CSI-RS resources is higher than the priority of the first set of information (G10~GM0), the second set of information (G11~GM1), and the third set of information (G12~GM2) corresponding to the (j-1)th resource, and among these, 1 ≤ j ≤ M; and The priority of the first set of information (G10~GM0) corresponding to the j-th resource is higher than the priority of the second set of information (G11~GM1), and the priority of the second set of information (G11~GM1) is higher than the priority of the third set of information (G12~GM2).

[0112] For example, in priority order 3, the priority order of each pair from highest to lowest is as follows: G0>G10>G11>G12>G20>G21>G22>…>GM0>GM1>GM2 And among them, G10, ..., GM0 represent the first set of information corresponding to each of the M CSIRS resources; G11, ..., GM1 represent a second set of information corresponding to each of the M CSIRS resources; and G12, ..., GM2 represent third-set information corresponding to each of the M CSIRS resources.
