The following explains some concepts and/or terms related in the method, the device and the terminal for reporting capability information provided by the embodiment of the present application.

Codebook-based physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) transmission mode:

the network side configures an uplink sounding reference signal (Sounding Reference Signal, SRS resource sets, each containing at least one SRS resource) for a user equipment UE (may also be referred to as a terminal) based on codebook transmission, the UE transmits SRS according to the configured at least one SRS resource, so that the network side obtains an uplink channel expected by the UE by receiving the SRS transmitted by the UE, determines a beam, a precoding matrix, a modulation and coding scheme (Modulation and coding scheme, MCS) and the like of the UE based on PUSCH transmission based on the uplink channel, and notifies the UE by scheduling downlink control information (Downlink Control Information, DCI) of the PUSCH.

Then, the UE receives DCI scheduling PUSCH and selects one precoding matrix for scheduled PUSCH transmission from a predefined codebook based on a transmission precoding matrix index (Transmitted Precoding Matrix Index, TPMI) field indicated in the DCI. And the UE performs precoding on uplink data according to the indicated TPMI and then maps the uplink data to corresponding PUSCH resources for transmission. An example of the indication of TPMI indicated in DCI is shown in table 1 below.

Table 1 precoding information and number of layers for 4 antenna ports, maximum Rank (Rank) =2 or 3 when the transform precoder (transform precoder) is disabled.

PUSCH transmission mode based on non-codebook:

the network side configures SRS resource sets for UE based on non-codebook transmission, and each SRS resource set contains at least one SRS resource. Firstly, UE detects NZP CSI-RS (Non-Zero Power channel state information-Reference Signal) sent by a network side on Non-Zero Power (NZP) channel state information (Channel State Information, CSI) -Reference Signal (Reference Signal) resources configured by the network side to obtain downlink channel state information. The downstream channel information may be approximately equivalent to upstream channel information in terms of channel reciprocity. The UE calculates a candidate precoding matrix for uplink transmission according to the uplink channel information, and performs precoding and sending on SRS based on the precoding matrix in the candidate precoding matrix, and the network side further determines the precoding matrix used for PUSCH transmission according to the SRS after the precoding is measured, and informs the UE through DCI of the scheduling PUSCH.

Specifically, the network side may select a subset corresponding to an SRS resource index from a predefined SRI index table, that is, an SRI group, based on the SRS resource indication (SRS resource indicator, SRI) field of the DCI to notify the UE of a precoding matrix adopted by the precoding of the PUSCH, where an indication example is as shown in table 2 below.

Terminals with different capabilities can quickly and accurately transmit.

The embodiment of the application provides a capability information reporting method, and fig. 3 shows a flow chart of the capability information reporting method provided by the embodiment of the application. As shown in fig. 3, the method for reporting capability information provided by the embodiment of the present application may include the following steps 301 and 302.

Step 301, the terminal acquires terminal capability information.

And 302, the terminal reports the terminal capability information.

Wherein the terminal capability information includes at least one of: antenna coherence capability information, full power transmission capability information, and association relation information between an antenna port and a phase tracking reference signal PT-RS port.

In the embodiment of the application, the antenna coherence capability information is used for indicating the antenna coherence capability of the terminal, the full power transmission capability information is used for indicating the full power transmission capability of the terminal, and the association relationship information is used for indicating the association relationship between the antenna port of the terminal and the PT-RS port of the terminal.

It should be noted that, the coherence according to the embodiments of the present application may be understood as correlation, correlation degree, or mutual calibration capability (for example, the coherent antenna is a mutually calibrated antenna).

Alternatively, in the embodiment of the present application, the terminal capability information may be preconfigured, predefined, agreed-on by protocol, or sent by other devices.

Optionally, in the embodiment of the present application, the terminal may report the terminal capability information to the network side device (network side), so that the network side device schedules the terminal to transmit based on the terminal capability information.

The capability information reporting method provided by the embodiment of the application is described in detail below by taking the case that the terminal capability information at least comprises antenna coherence capability information, full power transmission capability information or association relation information between an antenna port and a phase tracking reference signal PT-RS port as an example.

1. The terminal capability information may include at least antenna coherence capability information.

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

(1) the number (also called number, number) of antenna ports in the coherent antenna port group of the terminal, (2) a combination (set) of antenna port identifications in the coherent antenna port group of the terminal, (3) a grouping manner of the coherent antenna port group of the terminal, and (3) two groups of antenna port coherence types of the terminal.

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

For example, in the above (2), as shown in fig. 4, it is assumed that the terminal includes 8 antenna ports, and antenna port identifications of the 8 antenna ports are respectively: 1000. 1001, 1002, 1003, 1004, 1005, 1006 and 1007, wherein the combination of antenna port identifications in the coherent antenna port group of the terminal may comprise at least a partial combination of: combination 1{1000, 1004, 1001, 1005}, combination 2{1002, 1006, 1003, 1007}, combination 3{1001, 1005, 1002, 1006}; alternatively, as shown in fig. 4 (b), the combination of antenna port identifications in the coherent antenna port group of the terminal may include at least a partial combination of: 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}.

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

It will be appreciated 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 2,4,6 or 8 antenna ports of the terminal are a group of coherent antenna ports.

Alternatively, for a terminal supporting 8-antenna transmission, 2 antenna ports, 4 antenna ports, and 6 antenna ports as a set of coherent antenna ports may also be described as partially coherent; a group of 8 antenna ports that are coherent may also be described as being fully coherent.

Optionally, in the embodiment of the present application, for a precoding matrix with 2 antenna ports being a group of coherent antenna ports, only two elements are non-zero in a column of the precoding matrix at maximum.

Optionally, in the embodiment of the present application, for a precoding matrix with 2 antenna ports as a group of coherent antenna ports, only four elements are non-zero in a column of the precoding matrix at maximum.

It may be understood that, in the embodiment of the present application, the network side device configures precoding of uplink transmission of the terminal that meets the capability according to the capability (for example, antenna coherence capability information) reported by the terminal.

Optionally, in the embodiment of the present application, each of the foregoing (1) and (2) may indicate the number of antenna ports in each group of coherent antenna ports supported by the terminal.

Optionally, in the embodiment of the present application, if the terminal reports that 4 antenna ports are supported as a group of coherent antenna ports, the method indicates that: the terminal supports 2 antenna ports as a group of coherent antenna ports at the same time, or the terminal supports all the antenna ports incoherently at the same time;

if the terminal reports that 6 antenna ports are supported as a group of coherent antenna ports, the method indicates that: the terminal supports 2 and/or 4 antenna ports as a group of coherent antenna ports at the same time, or the terminal supports all the antenna ports incoherently at the same time;

if the terminal reports that 8 antenna ports are supported as a group of coherent antenna ports, the method indicates that: the terminal supports at least one of 2 antenna ports, 4 antenna ports and 6 antenna ports as a set of coherent antenna ports at the same time, or the terminal supports all antenna ports incoherently at the same time.

It should be noted that, in the embodiment of the present application, the antenna ports are incoherent, which is understood that no calibration (or no calibration is required) between the antenna ports.

Optionally, in an embodiment of the present application, the grouping manner may include at least one of the following: the 2 antenna ports are a group of coherent antenna ports; the 4 antenna ports are a set of coherent antenna ports.

Optionally, in an embodiment of the present application, the grouping manner may include at least one of the following: the 2 antenna ports are a group of coherent antenna ports; the 4 antenna ports are a group of coherent antenna ports, the 6 antenna ports are a group of coherent antenna ports, and the 8 antenna ports are a group of coherent antenna ports.

Optionally, in the embodiment of the present application, if the terminal supports 6 antenna transmission, the grouping manner may include at least one of the following:

1) The 6 antenna ports are divided into 3 groups of coherent antenna ports, wherein each group of coherent antenna ports comprises 2 antenna ports.

2) The 6 antenna ports are divided into 2 groups of coherent antenna ports, wherein 1 group of coherent antenna ports comprises 2 antenna ports, and the other 1 group of coherent antenna ports comprises 4 antenna ports.

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

If the terminal supports 8-antenna transmission, the grouping manner may include at least one of the following:

1) The 8 antenna ports are divided into 2 groups of coherent antenna ports, wherein each group of antenna ports comprises 4 antenna ports.

2) The 8 antenna ports are divided into 4 groups of coherent antenna ports, wherein each group of coherent antenna ports comprises 2 antenna ports.

3) The method comprises the steps of grouping 8 antenna ports into 3 groups of coherent antenna ports, wherein 2 groups of coherent antenna ports respectively comprise 2 antenna ports, and 1 group of coherent antenna ports respectively comprise 4 antenna ports.

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

It should be noted that the antenna port identifiers of the antenna ports in each group of coherent antenna ports may be continuous or discontinuous.

Illustratively, taking the example that the antenna port identifications of the antenna ports in each group of the coherent antenna ports are continuous and the 8 antenna ports are divided into 3 groups of the coherent antenna ports, assuming that the 8 antenna ports are arranged in order of increasing antenna port identifications, then:

1) The first 4 antenna ports are a first group of coherent antenna ports, the 5 th antenna port and the 6 th antenna port are a second group of coherent antenna ports, and the 7 th antenna port and the 8 th antenna port are a third group of coherent antenna ports; i.e. 4+2+2. Or alternatively, the process may be performed,

2) The first 2 antenna ports are a first group of coherent antenna ports, the 3 rd to 6 th antenna ports are a second group of coherent antenna ports, and the 7 th and 8 th antenna ports are a third group of coherent antenna ports; i.e. 2+4+2. Or alternatively, the process may be performed,

3) The first 2 antenna ports are a first group of coherent antenna ports, the 3 rd antenna port and the 4 th antenna port are a second group of coherent antenna ports, and the 5 th to 8 th antenna ports are a third group of coherent antenna ports; i.e. 2+4.

Optionally, in an embodiment of the present application, each of the two sets of antenna port coherence types may include at least one of the following: fully coherent, partially coherent, incoherent.

In the embodiment of the present application, if the coherence type of a group of antenna ports is complete coherence, it indicates that the coherence between all antenna ports in the group of antenna ports meets a preset coherence condition, for example, the correlation degree between all antenna ports in the group of antenna ports is greater than or equal to a preset correlation degree value; if the coherence type of the antenna ports is partial coherence, the coherence between the partial antenna ports in the antenna ports satisfies a preset coherence condition, for example, the correlation degree between the partial antenna ports in the antenna ports is greater than or equal to a preset correlation degree value; if the coherence type of a group of antenna ports is incoherent, it indicates that the coherence between all antenna ports in the group of antenna ports does not satisfy a preset coherence condition, for example, the correlation degree between all antenna ports in the group of antenna ports is smaller than a preset correlation degree value.

Optionally, the two sets of antenna port coherence types may include any of the following:

{ fully coherent, fully coherent };

{ partially coherent, partially coherent };

{ incoherent, incoherent };

{ all coherent, partially coherent and incoherent, all coherent, partially coherent, incoherent };

{ partially coherent and incoherent, partially coherent and incoherent };

{ all coherent and partially coherent, incoherent, partially coherent and incoherent };

{ partially coherent and incoherent, fully coherent, partially coherent and incoherent }.

2. The terminal capability information at least comprises full power transmission capability information

Optionally, the full power transmission capability information may include at least one of: and a candidate set of the number of antenna ports configured by SRS resources and a precoding matrix group supporting full-power transmission of the terminal.

It should be noted that, in the embodiment of the present application, the power amplifying device corresponding to each antenna/antenna port in the terminal may be non-ideal. When the power amplifying means corresponding to each antenna/antenna port in the terminal may be non-ideal, the terminal may be considered to be transmitting simultaneously for multiple antenna ports, and full power of the terminal may be achieved. Therefore, the terminal can report a plurality of precoding matrixes supporting simultaneous transmission of antenna ports lower than the full power, so as to indicate that the terminal precodes uplink data and adopts the antenna ports to achieve maximum transmission power for simultaneous transmission, and the total transmission power of the terminal can achieve the full power of the terminal, namely the full power transmission can be achieved.

Specifically, when the terminal uses each number of antenna ports in the candidate set to transmit/transmit simultaneously, the terminal can realize full power transmission. When the terminal adopts the antenna ports corresponding to the non-zero transmitting power in each precoding matrix in the precoding matrix group supporting the full-power transmission of the terminal to transmit/transmit simultaneously, the terminal can realize the full-power transmission.

It should be noted that, in the embodiment of the present application, each row of the precoding matrix corresponds to one antenna port of the terminal.

Optionally, in the embodiment of the present application, the candidate set includes a plurality of antenna port numbers, and after the terminal reports the terminal capability information including the candidate set, the network side device may configure the antenna ports for SRS resources of the terminal based on at least a part of the antenna port numbers in the candidate set.

Optionally, in an embodiment of the present application, the candidate set includes at least one of the following a to h:

a，{1，6}；

b，{1，2，6}；

c，{1，4，6}；

d，{1，2，4，6}；

e，{1，8}；

f，{1，2，8}；

g，{1，4，8}；

h，{1，2，4，8}。

optionally, any of a, b, c, d may be reported for a terminal supporting 6 antenna transmission; any one of e, f, g, h may be reported for a terminal supporting 8 antenna transmission.

Optionally, in the embodiment of the present application, the terminal includes a plurality of SRS resources, and the number of antenna ports configured by the network side device for each SRS resource may be one number in the candidate set.

The network side equipment can configure different numbers of antenna ports in the candidate set for different SRS resources; or, the network device may configure the same number of antenna ports in the candidate set for different SRS resources, and may specifically be determined according to the actual use requirement.

For example, when the network side configures two SRS resources for the terminal, one SRS resource configures 8 antenna ports, and the other SRS resource configures 4 antenna ports. If the 8 antenna ports of the terminal cannot achieve full power transmission by adopting incoherent precoding, when the network side device indicates that the SRS resources of the 4 antenna ports are scheduled to transmit PUSCH, the terminal may virtualize the 8 antennas (for example, the antenna ports of the 8 antennas) of the terminal through techniques such as antenna virtualization, for example, two antennas correspond to one SRS resource (that is, one SRS resource is simultaneously transmitted by adopting 2 antenna ports), so as to achieve full power transmission.

For another example, assume that the candidate set includes b as described above: {1,2,6}, then: if the terminal includes 2 SRS resources, namely SRS resource 1 and SRS resource 2, then:

1) The network side equipment can configure 1 antenna port for SRS resource 1 and 2 antenna ports for SRS resource 2; i.e., different SRS resources configure different numbers of antenna ports in the candidate set. Or alternatively, the process may be performed,

2) The network side device may configure 2 antenna ports for SRS resource 1, and configure 2 antenna ports for SRS resource 2, i.e. the same number of antenna ports in different SRS resource configuration candidate sets.

Optionally, in the embodiment of the present application, the network side device may configure the same antenna port or different antenna ports for different SRS resources.

It can be understood that, in the embodiment of the present application, for the precoding matrix supporting the full power transmission of the terminal, 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, where the transmission power of the precoded uplink data can reach the full power.

Optionally, in the embodiment of the present application, the precoding matrix group supporting full power transmission of the terminal may include at least one of the following:

i) The first precoding matrix group, the first precoding matrix group may include: precoding matrixes adopted when the terminal supports 6-antenna transmission and supports 2 antenna ports as a group of coherent antenna ports, wherein the precoding matrixes in a first precoding matrix group satisfy the following conditions: the antenna ports corresponding to the non-zero transmit power are the same.

Optionally, in an embodiment of the present application, the precoding matrix in the first precoding matrix group may include at least one of the following:

it should be noted that, the precoding matrix groups supporting the full power transmission of the terminal may include one or more first precoding matrix groups.

ii) a second set of precoding matrices, the second set of precoding matrices may comprise: precoding matrixes adopted when the terminal supports 6-antenna transmission and supports 4 antenna ports as a group of coherent antenna ports, wherein the precoding matrixes in the second precoding matrix group satisfy the following conditions: the antenna ports corresponding to the non-zero transmit power are the same.

Optionally, in an embodiment of the present application, the precoding matrix in the second precoding matrix group may include at least one of the following:

alternatively, in the embodiment of the present application, each precoding matrix in the second precoding matrix group may be multiplied by one normalization coefficient.

iii) A third precoding matrix group, the third precoding matrix group comprising: the precoding matrix adopted when the terminal supports 8-antenna transmission and supports 2 antenna ports as a group of coherent antenna ports, and the precoding matrix in the third precoding matrix group satisfies: the antenna ports corresponding to the non-zero transmit power are the same.

Optionally, in an embodiment of the present application, the precoding matrix in the third precoding matrix group may include at least one of the following:

/>

iii) a fourth precoding matrix group, the fourth precoding matrix group comprising: the precoding matrix adopted when the terminal supports 8-antenna transmission and supports 4 antenna ports as a group of coherent antenna ports, and the precoding matrix in the fourth precoding matrix group satisfies: the antenna ports corresponding to the non-zero transmit power are the same.

The number of the fourth precoding matrix groups may be one or a plurality of.

Optionally, in an embodiment of the present application, the precoding matrix in the fourth precoding matrix group may include at least one of the following:

it should be noted that, each precoding matrix mentioned in the embodiment of the present application may be multiplied by a normalization coefficient.

It may be understood that, in the embodiment of the present application, the terminal supports 6 antenna transmission, and the precoding matrix group may include at least one of the foregoing i and ii; the terminal supports 8 antenna transmission, and the precoding matrix group may include at least one of iii and iii.

The capability reporting method provided by the embodiment of the application is exemplarily described below with reference to a specific example.

For example, for a terminal supporting 8-antenna transmission, the power amplifying device corresponding to each antenna may be non-ideal, for example, the output power corresponding to each antenna is at most 20dBm, and the full power transmission of the terminal is 23dBm, in which case, the terminal considers that when two antenna ports transmit simultaneously, the terminal may reach 23dBm, so that a precoding matrix that two antenna ports supporting 20dBm transmit simultaneously may be reported: such as matrix 1 and matrix 2 described below.

Each element in a column of elements in the matrix 1 corresponds to one antenna port, and it can be seen from the matrix 1 that the modulus of the element corresponding to the 1 st antenna port and the 5 th antenna port is 1, which indicates that after the terminal uses the matrix 1 to precode uplink data, the two antenna ports reach the maximum transmitting power, namely 20dBm, and transmit simultaneously, and in this case, the total power reaches 23dBm, namely, full power transmission is realized.

The matrix 2 is a two-stream matrix, each column corresponds to one stream (i.e. data stream), the first element of the matrix 2 in the first column is non-zero, which means that the first stream data is sent through the 1 st antenna port, the fifth element of the second column of the matrix 2 is non-zero, which means that the second stream data is sent through the fifth antenna port, so that the sum of the transmitting power of the two streams of data can reach full power.

It will be appreciated that the antenna ports for non-zero transmit power in matrix 1 and matrix 2 are identical, being the 1 st antenna port and the 5 th antenna port.

For another example, for a terminal supporting 8-antenna transmission, the terminal may implement 4-antenna port coherence, where the 4-antenna ports simultaneously transmit uplink data to achieve full power transmission, and the terminal may report a precoding matrix that is simultaneously transmitted by the 4 antennas: such as matrix 1 and matrix 2 described below.

From the matrix 3, it can be seen that the precoding element corresponding to the 1 st, 2 nd, 4 th and 5 th antenna ports of the terminal is non-zero, which means that when the four antenna ports transmit simultaneously, the sum of the transmitting power can reach the full power.

The matrix 4 is a 4-stream matrix, each column corresponds to one stream, and as can be seen from the matrix 4, the antenna ports of the terminal are incoherent, and 4-stream data can be sent by the same 4 antenna ports to realize simultaneous transmission, so that full power is achieved.
