[0023] The following explains some concepts and / or terms involved in the capability information reporting method, device and terminal provided in the embodiments of this application.

[0024] Codebook-based Physical Uplink Shared Channel (PUSCH) transmission mode:

[0025] The network side configures uplink sounding reference signals (SRS resource sets, each containing at least one SRS resource) for codebook-based transmission to the user equipment (UE). The UE transmits SRS according to at least one configured SRS resource, thereby obtaining the uplink channel desired by the UE by receiving the SRS transmitted by the UE. Based on this, the network side determines the beam, precoding matrix, modulation and coding scheme (MCS), etc., for the UE's transmission based on PUSCH, and notifies the UE by scheduling downlink control information (DCI) for PUSCH.

[0026] Then, the UE receives the DCI for scheduling the PUSCH and selects a precoding matrix from a predefined codebook for the scheduled PUSCH transmission based on the Transmitted Precoding Matrix Index (TPMI) field indicated in the DCI. The UE precodes the uplink data according to the indicated TPMI and maps it to the corresponding PUSCH resource for transmission. An example of the TPMI indicated in the DCI is shown in Table 1 below.

[0027] Table 1: Precoding information and number of layers for the 4 antenna ports. When the transform precoder is disabled, the maximum rank is 2 or 3.

[0028]

[0029]

[0030] Non-codebook-based PUSCH transmission mode:

[0031] The network configures SRS resource sets for the UE for non-codebook-based transmission, with each SRS resource set containing at least one SRS resource. First, the UE detects the NZPCSI-RS (Non-Zero Power Channel State Information-Reference Signal) transmitted by the network on the Non-Zero Power (NZP) Channel State Information (CSI)-Reference Signal resources configured by the network to obtain downlink channel state information. Based on channel reciprocity, this downlink channel information can be approximately equivalent to uplink channel information. The UE calculates candidate precoding matrices for uplink transmission based on the uplink channel information, precodes the SRS based on the precoding matrices in the candidate precoding matrices, and transmits it. The network further determines the precoding matrix used for PUSCH transmission based on the measured precoded SRS and notifies the UE through the DCI of PUSCH scheduling.

[0032] Specifically, the network side can select a subset of SRS resource indexes from a predefined SRI index table, i.e., an SRI group, based on the SRS resource indicator (SRI) field of DCI, to notify UEPUSCH of the precoding matrix used for precoding. An example of the indication is shown in Table 2 below.

[0035] The capability information reporting method, apparatus, and terminal provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0036] Currently, terminals support a maximum of 4 antennas for transmission. When 6 or 8 antennas are introduced in the future, to ensure that the network side schedules terminal transmission based on the terminal's capabilities, this application provides a method for terminal reporting capabilities when using 6, 8, or more antennas for transmission. This enables terminals with different capabilities to transmit quickly and accurately.

[0037] This application provides a method for reporting capability information. Figure 3 A flowchart illustrating a capability information reporting method provided in an embodiment of this application is shown. Figure 3 As shown, the capability information reporting method provided in this application embodiment may include the following steps 301 and 302.

[0038] Step 301: The terminal obtains terminal capability information.

[0039] Step 302: The terminal reports its capabilities.

[0040] The terminal capability information includes at least one of the following: antenna coherence capability information, full-power transmission capability information, and correlation information between the antenna port and the phase tracking reference signal PT-RS port.

[0041] In this embodiment, the antenna coherence capability information is used to indicate the antenna coherence capability of the terminal, the full power transmission capability information is used to indicate the full power transmission capability of the terminal, and the association relationship information is used to indicate the association relationship between the antenna port and the PT-RS port of the terminal.

[0042] It should be noted that the coherence described in the embodiments of this application can be understood as correlation, degree of correlation, or mutual calibration capability (for example, a coherent antenna is a mutually calibrated antenna).

[0043] Optionally, in this embodiment of the application, the aforementioned terminal capability information may be pre-configured, pre-defined, protocol-agreed, or sent by other devices.

[0044] Optionally, in this embodiment of the application, the terminal may report terminal capability information to the network-side device (network side) so that the network-side device can schedule the terminal to perform transmission based on the terminal capability information.

[0045] The following describes in detail the capability information reporting method provided in the embodiments of this application, taking as examples the terminal capability information including at least antenna coherence capability information, full power transmission capability information, or the correlation information between the antenna port and the phase tracking reference signal PT-RS port.

[0046] First, terminal capability information may include at least antenna coherence capability information.

[0047] Optionally, the antenna coherence capability information mentioned above may include at least one of the following (1) to (3):

[0048] (1) The number of antenna ports in the coherent antenna port group of the terminal (also known as quantity or number), (2) The combination (set) of antenna port identifiers in the coherent antenna port group of the terminal, (3) The grouping method of the coherent antenna port group of the terminal, (4) The coherence type of the two groups of antenna ports of the terminal.

[0049] For example, in (1) above, the number of antenna ports in each coherent antenna port group of the terminal can be 1, 2, 4, 6 or 8.

[0050] For example, in (2) above, such as Figure 4As shown, assume the terminal has 8 antenna ports, labeled 1000, 1001, 1002, 1003, 1004, 1005, 1006, and 1007. Figure 4 As shown in (a), the combination of antenna port identifiers in the coherent antenna port group of the terminal may include at least some of the following combinations: combination 1 {1000, 1004, 1001, 1005}, combination 2 {1002, 1006, 1003, 1007}, combination 3 {1001, 1005, 1002, 1006}; or, as Figure 4 As shown in (b), the combination of antenna port identifiers in the coherent antenna port group of the terminal may include at least some of the following combinations: combination 4 {1000, 1004, 1001, 1005}, combination 5 {1000, 1004, 1002, 1006}, combination 6 {1002, 1006, 1003, 1007} ​​and combination 7 {1001, 1005, 1003, 1007}.

[0051] Optionally, the terminal supports 6-antenna transmission, and the number of candidate antenna ports in the coherent antenna port group of the terminal is a subset of the set {2, 4, 6}; or, the terminal supports 8-antenna transmission, and the number of candidate antenna ports in the coherent antenna port group of the terminal is a subset of the set {2, 4, 6, 8}.

[0052] It can be understood that when the number of antenna ports in the coherent antenna port group of the terminal is 2, 4, 6 or 8, it means that the 2, 4, 6 or 8 antenna ports of the terminal form a coherent antenna port group.

[0053] Alternatively, for terminals that support 8-antenna transmission, a group of 2 antenna ports, 4 antenna ports, and 6 antenna ports can be described as partially coherent; a group of 8 antenna ports can be described as fully coherent.

[0054] Optionally, in this embodiment of the application, for a precoding matrix consisting of two antenna ports as a group of coherent antenna ports, a column of the precoding matrix has a maximum of only two non-zero elements.

[0055] Optionally, in this embodiment of the application, for a precoding matrix consisting of two antenna ports as a group of coherent antenna ports, a maximum of only four non-zero elements are present in a column of the precoding matrix.

[0056] It is understood that in this embodiment of the application, the network-side device configures the precoding of the uplink transmission of the terminal that meets the capabilities reported by the terminal (e.g., antenna coherence capability information).

[0057] Optionally, in the embodiments of this application, (1) and (2) above can both indicate the number of antenna ports in each group of coherent antenna ports supported by the terminal.

[0058] Optionally, in this embodiment of the application, if the terminal reports that it supports 4 antenna ports as a group of coherent antenna ports, it means that the terminal simultaneously supports 2 antenna ports as a group of coherent antenna ports, or the terminal simultaneously supports all antenna ports as incoherent.

[0059] If the terminal reports that it supports 6 antenna ports as a group of coherent antenna ports, it means that the terminal simultaneously supports 2 and / or 4 antenna ports as a group of coherent antenna ports, or the terminal simultaneously supports all antenna ports as incoherent.

[0060] If the terminal reports that it supports 8 antenna ports as a group of coherent antenna ports, it means that the terminal supports at least one of 2 antenna ports, 4 antenna ports, and 6 antenna ports as a group of coherent antenna ports, or the terminal supports all antenna ports as incoherent.

[0061] It should be noted that the incoherence of the antenna ports in this embodiment can be understood as the fact that no calibration is required between these antenna ports.

[0062] Optionally, in the embodiments of this application, the above grouping method may include at least one of the following: two antenna ports form a group of coherent antenna ports; four antenna ports form a group of coherent antenna ports.

[0063] Optionally, in the embodiments of this application, the above grouping method may include at least one of the following: 2 antenna ports as a group of coherent antenna ports; 4 antenna ports as a group of coherent antenna ports; 6 antenna ports as a group of coherent antenna ports; 8 antenna ports as a group of coherent antenna ports.

[0064] Optionally, in this embodiment of the application, if the terminal supports 6-antenna transmission, the above grouping method may include at least one of the following:

[0065] 1) Divide the 6 antenna ports into 3 groups of coherent antenna ports, with each group of coherent antenna ports including 2 antenna ports.

[0066] 2) Divide the 6 antenna ports into 2 groups of coherent antenna ports, one group of coherent antenna ports includes 2 antenna ports, and the other group of coherent antenna ports includes 4 antenna ports.

[0067] The grouping methods in 1) and 2) above can also be described as partially coherent.

[0068] If the terminal supports 8-antenna transmission, the above grouping method may include at least one of the following:

[0069] 1) Divide the 8 antenna ports into 2 groups of coherent antenna ports, with each group containing 4 antenna ports.

[0070] 2) Divide the 8 antenna ports into 4 groups of coherent antenna ports, with each group of coherent antenna ports including 2 antenna ports.

[0071] 3) Divide the 8 antenna ports into 3 groups of coherent antenna ports, where 2 groups of coherent antenna ports each contain 2 antenna ports, and 1 group of coherent antenna ports contains 4 antenna ports.

[0072] The grouping methods in 1), 2) and 3) above can also be described as partially coherent.

[0073] It should be noted that the antenna port identifiers in each group of coherent antenna ports can be continuous or discontinuous.

[0074] For example, assuming the antenna port identifiers of the antenna ports in each group of coherent antenna ports are consecutive, and the 8 antenna ports are divided into 3 groups of coherent antenna ports, and assuming the 8 antenna ports are arranged in ascending order of their antenna port identifiers, then:

[0075] 1) The first four antenna ports form the first group of coherent antenna ports, the fifth and sixth antenna ports form the second group of coherent antenna ports, and the seventh and eighth antenna ports form the third group of coherent antenna ports; that is, 4+2+2. Alternatively,

[0076] 2) The first two antenna ports form the first group of coherent antenna ports, the third to sixth antenna ports form the second group of coherent antenna ports, and the seventh and eighth antenna ports form the third group of coherent antenna ports; that is, 2+4+2. Alternatively,

[0077] 3) The first two antenna ports are the first group of coherent antenna ports, the third and fourth antenna ports are the second group of coherent antenna ports, and the fifth to eighth antenna ports are the third group of coherent antenna ports; that is, 2+2+4.

[0078] Optionally, in the embodiments of this application, each of the two sets of antenna port coherence types may include at least one of the following: fully coherent, partially coherent, or incoherent.

[0079] In this embodiment, if a group of antenna ports has a coherence type of fully coherent, it means that the coherence between all antenna ports in the group satisfies a preset coherence condition, for example, the correlation between all antenna ports in the group is greater than or equal to a preset correlation value; if a group of antenna ports has a coherence type of partially coherent, it means that the coherence between some antenna ports in the group satisfies a preset coherence condition, for example, the correlation between some antenna ports in the group is greater than or equal to a preset correlation value; if a group of antenna ports has a coherence type of incoherent, it means that the coherence between all antenna ports in the group does not satisfy the preset coherence condition, for example, the correlation between all antenna ports in the group is less than a preset correlation value.

[0080] Optionally, the coherence types of the two sets of antenna ports mentioned above may include any of the following:

[0081] {Completely coherent, completely coherent};

[0082] {Partially coherent, partially coherent};

[0083] {Incoherent, Incoherent};

[0084] {Fully coherent, partially coherent, and incoherent; fully coherent, partially coherent, and incoherent};

[0085] {Partially coherent and incoherent, partially coherent and incoherent};

[0086] {Fully coherent and partially coherent, incoherent, partially coherent and incoherent};

[0087] {Partially coherent and incoherent, fully coherent, partially coherent and incoherent}.

[0088] II. The terminal capability information should include at least full-power transmission capability information.

[0089] Optionally, the above-mentioned full-power transmission capability information may include at least one of the following: a candidate set of the number of antenna ports configured in the SRS resource configuration, and a precoding matrix group that supports full-power transmission of the terminal.

[0090] It should be noted that in this embodiment, the power amplification device corresponding to each antenna / antenna port in the terminal may be non-ideal. When the power amplification device corresponding to each antenna / antenna port in the terminal may be non-ideal, the terminal can assume that when multiple antenna ports transmit simultaneously, the terminal's full power can be achieved. Therefore, the terminal can report multiple precoding matrices that support simultaneous transmission of antenna ports below the full power, indicating that by precoding uplink data and simultaneously transmitting it using the maximum transmission power of these antenna ports, the terminal's total transmission power can reach its full power, thus achieving full-power transmission.

[0091] Specifically, the terminal can achieve full-power transmission when it uses each number of antenna ports in the candidate set to transmit simultaneously. The terminal can also achieve full-power transmission when it uses the antenna ports corresponding to the non-zero transmit power in each precoding matrix of the precoding matrix group that supports full-power transmission.

[0092] It should be noted that each row of the precoding matrix in this embodiment corresponds to an antenna port of the terminal.

[0093] Optionally, in this embodiment of the application, the candidate set includes multiple antenna port numbers. After the terminal reports terminal capability information including the candidate set, the network-side device can configure antenna ports for the terminal's SRS resources based on at least a portion of the antenna port numbers in the candidate set.

[0094] Optionally, in embodiments of this application, the candidate set includes at least one of the following a to h:

[0095] a, {1, 6};

[0096] b, {1, 2, 6};

[0097] c, {1, 4, 6};

[0098] d, {1, 2, 4, 6};

[0099] e, {1, 8};

[0100] f, {1, 2, 8};

[0101] g, {1, 4, 8};

[0102] h, {1, 2, 4, 8}.

[0103] Optionally, for terminals that support 6-antenna transmission, any one of a, b, c, and d can be reported; for terminals that support 8-antenna transmission, any one of e, f, g, and h can be reported.

[0104] Optionally, in this embodiment of the application, the terminal includes multiple SRS resources, and the number of antenna ports configured by the network-side device for each SRS resource can be one of the candidate sets.

[0105] Network-side devices can configure different numbers of antenna ports from the candidate set for different SRS resources; alternatively, network devices can configure the same number of antenna ports from the candidate set for different SRS resources, depending on actual usage requirements.

[0106] For example, when the network configures two SRS resources for the terminal, one with 8 antenna ports and the other with 4 antenna ports, if the terminal's 8 antenna ports cannot achieve full-power transmission using non-phase interference coding, then when the network device instructs the scheduling of the 4 antenna ports' SRS resources for PUSCH transmission, the terminal can use antenna virtualization and other technologies to virtualize the terminal's 8 antennas (e.g., the antenna ports of the 8 antennas). For example, two antennas can correspond to one SRS resource (i.e., using 2 antenna ports to transmit one SRS resource simultaneously) to achieve full-power transmission.

[0107] For example, assuming the candidate set includes b: {1, 2, 6}, then: if the terminal includes two SRS resources, SRS resource 1 and SRS resource 2, then:

[0108] 1) The network-side device can configure one antenna port for SRS resource 1 and two antenna ports for SRS resource 2; that is, different numbers of antenna ports in different SRS resource configuration candidate sets. Alternatively,

[0109] 2) The network-side device can configure 2 antenna ports for SRS resource 1 and 2 antenna ports for SRS resource 2, that is, the same number of antenna ports in different SRS resource configuration candidate sets.

[0110] Optionally, in this embodiment of the application, the network-side device can configure the same antenna port or different antenna ports for different SRS resources.

[0111] It is understood that in the embodiments of this application, for a precoding matrix that supports full-power transmission of the terminal, when the terminal uses the precoding matrix to precode the uplink data and maps the precoded uplink data to the uplink channel (e.g., PUSCH) resources configured on the network side for transmission, the transmission power of the precoded uplink data can reach full power.

[0112] Optionally, in this embodiment of the application, the precoding matrix group supporting full-power transmission of the terminal may include at least one of the following:

[0113] i) A first precoding matrix group, which may include: a precoding matrix used when the terminal supports 6-antenna transmission and supports 2 antenna ports as a group of coherent antenna ports, wherein the precoding matrices in the first precoding matrix group satisfy the following: the antenna ports corresponding to non-zero transmit power are the same.

[0121] ii) A second precoding matrix group, which may include: a precoding matrix used when the terminal supports 6-antenna transmission and supports 4 antenna ports as a group of coherent antenna ports, wherein the precoding matrices in the second precoding matrix group satisfy the following: the antenna ports corresponding to non-zero transmit power are the same.

[0122] Optionally, in embodiments of this application, the precoding matrix in the second precoding matrix group may include at least one of the following:

[0123]

[0124] Optionally, in the embodiments of this application, each precoding matrix in the second precoding matrix group may be multiplied by a normalization coefficient.

[0125] iii) The third precoding matrix group includes: the precoding matrix used when the terminal supports 8-antenna transmission and supports 2 antenna ports as a group of coherent antenna ports. The precoding matrices in the third precoding matrix group satisfy the following: the antenna ports corresponding to non-zero transmit power are the same.

[0126] Optionally, in embodiments of this application, the precoding matrix in the third precoding matrix group may include at least one of the following:

[0127]

[0128] Optionally, in embodiments of this application, the precoding matrix in the third precoding matrix group may include at least one of the following:

[0142]

[0143] It should be noted that each precoding matrix mentioned in the embodiments of this application can be multiplied by a normalization coefficient.

[0144] It is understood that in the embodiments of this application, if the terminal supports 6-antenna transmission, the precoding matrix group may include at least one of i and ii above; if the terminal supports 8-antenna transmission, the precoding matrix group may include at least one of iii and iiii above.

[0145] The capability reporting method provided in this application embodiment will be illustrated below with specific examples.

[0146] For example, for a terminal that supports 8-antenna transmission, the power amplifier corresponding to each antenna may be non-ideal. For example, the maximum output power of each antenna is 20dBm, while the full power transmission of the terminal is 23dBm. In this case, the terminal believes that 23dBm can be achieved when both antenna ports transmit at the same time, so it can report the precoding matrix that both antenna ports supporting 20dBm transmission power transmit at the same time: for example, matrix 1 and matrix 2 below.

[0147] In matrix 1, each element in a column corresponds to an antenna port. As can be seen from matrix 1, the modulus of the elements corresponding to the first and fifth antenna ports is 1. This indicates that after the terminal uses matrix 1 to precode the uplink data, both antenna ports reach the maximum transmit power of 20dBm and transmit simultaneously. In this case, the total power reaches 23dBm, which means full-power transmission is achieved.

[0148] Matrix 2 is a two-stream matrix, with each column corresponding to one stream (i.e., data stream). The first element of the first column of Matrix 2 is non-zero, indicating that the first stream of data is transmitted through the first antenna port. The fifth element of the second column of Matrix 2 is non-zero, indicating that the second stream of data is transmitted through the fifth antenna port. In this way, the sum of the transmission power of the two streams of data can also reach full power.

[0149] It is understandable that the antenna ports with non-zero transmit power in matrix 1 and matrix 2 are the same, namely the first antenna port and the fifth antenna port.

[0150] Matrix 1: Matrix 2:

[0151] For example, for a terminal that supports 8-antenna transmission, the terminal can achieve coherence of 4 antenna ports, and full power transmission can only be achieved when all 4 antenna ports send uplink data simultaneously. The terminal will report the precoding matrix of the 4 antennas sending data simultaneously: for example, matrix 1 and matrix 2 below.

[0152] As can be seen from matrix 3, the precoding elements corresponding to the 1st, 2nd, 4th and 5th antenna ports of the terminal are non-zero, indicating that when these four antenna ports transmit simultaneously, the sum of the transmission power can reach full power.

[0153] Matrix 4 is a 4-stream matrix, with each column corresponding to one stream. As can be seen from Matrix 4, the antenna ports of the terminal are incoherent and can transmit 4 streams of data simultaneously from the same 4 antenna ports to achieve full power.

[0154] Matrix 3: Matrix 4:

[0155] Third, the terminal capability information should include at least the association information between the antenna port and the PT-RS port.

[0156] Optionally, in this embodiment of the application, the aforementioned association information may include any of the following:

[0157] (1) The first antenna port group of the terminal shares the first PT-RS port, and the second antenna port group of the terminal shares the second PT-RS port; (2) A subset of the first antenna port group of the terminal shares the first PT-RS port, and a subset of the second antenna port group of the terminal shares the second PT-RS port. The antenna ports in different antenna port groups are different.

[0158] Optionally, in this embodiment of the application, the terminal includes two antenna port groups, namely a first antenna port group and a second antenna port group, and each antenna port group includes at least one antenna port.

[0159] Optionally, in the embodiments of this application, the first antenna port group and the second antenna port group can be any of the following: a coherent antenna port group or an incoherent antenna port group.

[0160] Optionally, in this embodiment of the application, the first PT-RS port and the second PT-RS port can be PT-RS port 0 or PT-RS port 1, and the first PT-RS port and the second PT-RS port are different.

[0161] The capability information reporting method provided in the embodiments of this application will be described exemplarily below.

[0162] For example, suppose the terminal includes 8 antenna ports, and the antenna port identifiers of these 8 antenna ports are 1000, 1001, 1002, 1003, 1004, 1005, 1006, and 1007, respectively. The first antenna port group is {1000, 1001, 1004, 1005}, and the second antenna port group is {1002, 1003, 1006, 1007}. Then:

[0163] The first antenna port group can share PT-RS port0, and the second antenna port group can share PT-RS port1; or, a subset of the first antenna port group can share PT-RS port0, and a subset of the second antenna port group can share PT-RS port1.

[0164] For example, suppose the terminal includes 6 antenna ports, and the antenna port identifiers of the 6 antenna ports are 1000, 1001, 1002, 1003, 1004 and 1005 respectively. The first antenna port group is {1000, 1003, 1001, 1004}, and the second antenna port group is {1002, 1005}. Then: the first antenna port group can share PT-RS port 0, and the second antenna port can share PT-RS port 1; or, a subset of the first antenna port group can share PT-RS port 0, and a subset of the second antenna port group can share PT-RS port 1.

[0165] Optionally, in this embodiment of the application, the terminal capability information may include multiple sets of capability information, each set of capability information corresponding to a target object of the terminal.

[0166] Optionally, in the embodiments of this application, the target object may include at least one of the following: antenna panel, Transmission Configuration Indicator (TCI) status, beam information, and SRS resources.

[0167] Optionally, in the embodiments of this application, for the above-mentioned multiple sets of capability information, in one approach, the information items in different sets of capability information are the same, but at least some of the capability information in different sets of capability information is different. In another approach, the information items in different sets of capability information are different.

[0168] It should be noted that in the embodiments of this application, each information item may include any one of the following: information item 1, information item 2, and information item 3.

[0169] Among them, information item 1 corresponds to the above-mentioned antenna coherence capability information, information item 2 corresponds to the above-mentioned full power transmission capability information, and information item 3 corresponds to the above-mentioned association relationship information between the antenna port and the PT-RS port.

[0170] It is understood that in the embodiments of this application, in one of the above methods, the terminal can report at least one of multiple sets of different capability information 1, multiple sets of different capability information 2, and multiple sets of different capability information 3 through the above multiple sets of capability information.

[0171] The following examples illustrate one of the above methods and another.

[0172] For example, in one of the above methods, assuming that the above multiple sets of capability information include 3 sets of capability information, then: the first set of capability information includes: the number of antenna ports in the coherent antenna port group of the terminal (i.e., information item 1) and the precoding matrix group (i.e., information item 2).

[0173] The second set of capability information includes: the combination of antenna port identifiers in the coherent antenna port group of the terminal (i.e., information item 1) and the precoding matrix group (i.e., information item 2);

[0174] The third set of capability information includes: the grouping method of the terminal's coherent antenna port groups and the coherence types of the two sets of antenna ports of the terminal (i.e., information item 1), and the precoding matrix group (i.e., information item 2). It can be seen that in the above method, at least one information type 1 in different sets of capability information corresponds to different information.

[0175] For example, in another approach described above, assuming that the multiple sets of capability information include three sets of capability information, then the first set of capability information may include antenna coherence capability information (i.e., information item 1), the second set of capability information may include full-power transmission capability information (i.e., information item 2), and the third set of capability information may include the association information between the antenna port and the PT-RS port (i.e., information item 3); that is, the information items in different sets of capability information are different.

[0176] Optionally, in this embodiment of the application, the terminal capability information may further include: the number of SRS resources that the terminal supports sending simultaneously (hereinafter referred to as the target number).

[0177] Optionally, in this embodiment of the application, the number of targets can be 6 or 8.

[0178] For example, if the terminal supports 6-antenna transmission, the number of the above targets is 6; or, if the terminal supports 8-antenna transmission, the number of the above targets is 8.

[0179] Optionally, in this embodiment of the application, the terminal may report capability information 1, capability information 2 and capability information 3 based on the codebook transmission mode, and report the target number based on the non-codebook transmission mode.

[0180] To facilitate understanding of the capability information reporting method provided in the embodiments of this application, the following example, using terminal capability information including antenna coherence capability information and full-power transmission capability information, will be used to illustrate the capability information reporting method provided in the embodiments of this application.

[0181] Example 1: The terminal supports 6-antenna transmission. Based on codebook transmission mode, the terminal can report two antenna ports as a group of coherent antenna ports (i.e., antenna coherence capability information, specifically: the grouping method of the terminal's coherent antenna port groups). Simultaneously, based on codebook transmission mode, it can report the precoding matrix group supporting full-power transmission as follows:

[0182]

[0183] Example 2: The terminal supports 6-antenna transmission. Based on codebook transmission mode, the terminal can report the number of coherent antenna ports (i.e., antenna coherence capability information, specifically the grouping method of the terminal's coherent antenna ports) that support a group of 4 antenna ports. It can also report the precoding matrix group that supports full-power transmission by the terminal based on codebook transmission mode.

[0184]

[0185] Example 3: The terminal supports 8-antenna transmission. Based on the codebook transmission mode, the terminal can report the number of coherent antenna ports (i.e., antenna coherence capability information, specifically: the terminal's coherent antenna port grouping) that supports two antenna ports per group, and based on the codebook transmission mode, report the precoding matrix group that supports full-power transmission by the terminal as follows:

[0186]

[0187] Example 4: The terminal supports 8-antenna transmission. The terminal can report that 4 antenna ports form a group of coherent antenna ports (i.e., antenna coherence capability information, specifically: the terminal's coherent antenna port grouping), and based on the codebook transmission mode, report the precoding matrix group that supports the terminal's full-power transmission as follows:

[0188]

[0189] It should be noted that the codebooks used in Examples 1 and 3 above are determined based on the 2Tx codebook corresponding to the uplink (UL), while the codebooks used in Examples 2 and 4 above are determined based on the 4Tx codebook corresponding to the UL.

[0190] In the capability information reporting method provided in this application embodiment, for terminals supporting 6, 8, or more antennas for transmission, the terminal can report its antenna coherence capability information, full-power transmission capability information, and the correlation information between the antenna port and the phase tracking reference signal (PT-RS) port to the network-side device. Therefore, the network-side device can schedule the terminal to perform transmission based on these reported capabilities. This enables the network-side device to transmit data to terminals supporting 6, 8, or more antennas.

[0191] Optionally, in this embodiment of the application, after step 302 above, the capability information reporting method provided in this embodiment of the application further includes the following steps 304 and 305.

[0192] Step 304: The terminal receives uplink transmission configuration or uplink transmission scheduling information.

[0193] Among them, the aforementioned uplink transmission configuration or uplink transmission scheduling information satisfies the aforementioned terminal capability information.

[0194] It is understood that in this embodiment of the application, the uplink transmission configuration or uplink transmission scheduling information is sent to the terminal by the network-side device after receiving the terminal capability information.

[0195] For example, after receiving terminal capability information, the network-side device can send uplink transmission configuration or uplink transmission scheduling information to the terminal after receiving the terminal's request to perform uplink transmission.

[0196] Step 305: The terminal performs uplink transmission according to the uplink transmission configuration or uplink transmission scheduling information.
