Referring to fig. 1, an embodiment of the present application provides a PUSCH transmitting method, including:

step 101: the terminal receives first configuration information from the network equipment, wherein the first configuration information comprises C _SRS 、B _SRS And a first configuration parameter;

step 102: terminal according to C _SRS And B _SRS Determining the SRS bandwidth of the sounding reference signal;

step 103: the terminal determines pre-coding granularity according to the first configuration information;

step 104: the terminal determines PUSCH sending precoding according to the SRS bandwidth and the precoding granularity;

in the embodiment of the application, the terminal is configured according to the network equipment C _SRS 、B _SRS And the first configuration parameter is used for determining the SRS bandwidth and the precoding granularity and determining PUSCH sending precoding according to the SRS bandwidth and the precoding granularity. Realizing bandwidth and network configuration according to SRSAnd determining the pre-coding granularity of the sub-band for sending the PUSCH according to the parameters, thereby realizing the pre-coding sending of the PUSCH by the uplink sub-band and improving the throughput of uplink data transmission.

Specifically, the terminal is according to C _SRS And B _SRS Determining SRS bandwidth, SRS transmission bandwidth and frequency domain position etc. from C _SRS And B _SRS The parameters are configured. C _SRS Indicating the configured wideband bandwidth for the UE, B _SRS Indicating the narrowband bandwidth, B _SRS =0 represents that SRS transmission bandwidth is wideband, B _SRS The SRS transmission bandwidth greater than 0 is a narrow band determined by m _ SRS, x.

In particular, it can be according to C in the aforementioned Table 1 _SRS And B _SRS The corresponding relation with the SRS bandwidth is determined, namely the terminal only needs to acquire the C configured by the network _SRS And B _SRS The corresponding SRS bandwidth can be directly determined.

In a possible implementation manner, the terminal determines the precoding granularity according to the first configuration information, which specifically includes two manners:

the first method is as follows: the terminal determines the precoding granularity according to a first formula, wherein the first formula is as follows:

N＝N1×4；

wherein N is precoding granularity, and N1 is a first configuration parameter.

In this embodiment of the present application, the precoding granularity is specifically configured as a multiple of 4, and is used to represent a multiple of 4 Physical Resource Blocks (PRBs), the network device configures the specific multiple N1, that is, a first configuration parameter, and the network configuration N1 is an integer greater than 0, so that the precoding granularity is N1 × 4 PRBs, for example: n1=1, then the precoding granularity is 4 PRBs, N1=2, then the precoding granularity is 8 PRBs. In this way, the terminal can directly determine the precoding granularity according to N1 configured by the network.

The second method comprises the following steps: the terminal determines the pre-coding granularity according to a second formula, wherein the second formula is as follows:

n is upward or toTaking the whole;

wherein N is precoding granularity, m _ SRS, x is SRS bandwidth, and x is B _SRS N1 is a first configuration parameter.

In the embodiment of the present application, the precoding granularity is specifically calculated by using the SRS bandwidth and the first configuration parameter, the calculation result is rounded up or down, and the maximum value of N1 depends on the value of m _ SRS.

In particular, when network configuration B _SRS When =0, the SRS transmission bandwidth is represented by C _SRS It is determined that the SRS bandwidth and position of each SRS transmission are the same, and the network configuration precoding granularity in such configuration may be a multiple of 4 PRBs (N1 × 4) or N = (m _ SRS,0/m 1) rounding down or rounding up.

When the network is configured B _SRS >At 0 time, from C _SRS And B _SRS The configuration determines the SRS bandwidth transmitted each time, and in such configuration, the network configures the precoding granularity to be a multiple of 4 PRBs (N2 × 4) or N = (m _ SRS, x/m 2) round-bottom or round-top, where x =1 or 2 or 3.

The network can configure a parameter corresponding to B _SRS =0 and B _SRS >0, e.g. network configuration, indicates a parameter A, when A equals 0, indicates B _SRS =0, when A equals 1 represents B _SRS >0; or the network may configure two parameters for B _SRS =0 and B _SRS >0, e.g. network configuration parameters B and C, representing B when the network indicates B _SRS =0, representing B when the network indicates C _SRS >0。

It should be noted that N1, N2, m1, and m2 are only used for distinguishing descriptions, and are specifically the first configuration parameter N1 configured when the network is configured.

In some embodiments, according to C _SRS 、B _SRS And the first configuration parameter terminal can determine the pre-coding granularity and the corresponding pre-coding sub-band quantity.

Example 1: network configuration C for terminal _SRS ＝62,B _SRS =0, when m _ SRS,0=272, that is to say the SRS bandwidth is 272 PRBs, if N1 is equal to 2, the precoding granularity is equal to 8, and there are 34 precodes in totalSub-bands.

Example 2: network configuration C for terminal _SRS ＝62,B _SRS =0, when m _ SRS,0=272, i.e. the SRS bandwidth is 272 PRBs, assuming N1=10, then N =272/10, the lower integer is equal to 27, i.e. the precoding granularity is 27 PRBs, but the last precoded subband has only 2 PRBs, and there are 11 precoded subbands.

Example 3: network configuration C for terminal _SRS ＝62,B _SRS =1, when m _ SRS,1=68, that is to say the SRS bandwidth is 68 PRBs, assuming N1=4, then N =68/4, the lower integer is equal to 17, that is, the precoding granularity is 17 PRBs, and there are 16 precoding subbands in total.

Example 4: network configuration C for terminal _SRS ＝62,B _SRS =3, when m _ SRS,3=4, that is to say the SRS bandwidth is 4 PRBs, assuming that if N1 is equal to 4, the precoding granularity is equal to 16 PRBs (multiple of 4), for a total of 272/16=17 precoded subbands.

In a possible implementation manner, the determining, by the terminal, the PUSCH transmission precoding according to the SRS bandwidth and the precoding granularity includes:

(1) The terminal divides the SRS into a plurality of pre-coding sub-bands according to the SRS bandwidth and the pre-coding granularity;

(2) And the terminal determines the PUSCH sending precoding according to the position relation between the plurality of precoding sub-bands and the frequency domain resources of the PUSCH.

In the embodiment of the application, the SRS is sub-band divided according to the determined precoding granularity, and then the PUSCH sending precoding is determined according to the position of the PUSCH frequency domain resource configured by the network.

Wherein, the PUSCH frequency domain resource of the network scheduling terminal may be dynamically indicated in the DCI.

Specifically, depending on whether the frequency domain resource starting position and ending position of the PUSCH overlap with the boundary of the precoding subband, the following cases may be included:

(1) Under the condition that the initial position and the end position of the frequency domain resource of the PUSCH are overlapped with the boundary of the pre-coding sub-band, the terminal divides the frequency domain resource of the PUSCH into a plurality of frequency domain resource sub-bands according to the pre-coding granularity and in a corresponding mode of aligning with the pre-coding sub-band, wherein the frequency domain resource sub-bands of the initial position and the end position are equal to the pre-coding granularity;

in the embodiment of the application, the starting position and the ending position of the frequency domain resource of the PUSCH are both overlapped with the boundary of the precoding sub-band, at this time, the frequency domain resource of the PUSCH is divided into a plurality of frequency domain resource sub-bands according to the precoding granularity, the frequency domain resource sub-bands and the precoding sub-bands are aligned one by one, and the PUSCH can be determined to send precoding only according to the alignment mode.

(2) Under the condition that the starting position and/or the ending position of the frequency domain resource of the PUSCH are/is not overlapped with the boundary of the pre-coding sub-band, the terminal divides the frequency domain resource of the PUSCH into a plurality of frequency domain resource sub-bands according to the pre-coding granularity and in a corresponding mode aligned with the pre-coding sub-band, wherein the frequency domain resource sub-bands of the starting position and/or the ending position are smaller than the pre-coding granularity;

in the embodiment of the present application, the non-overlapping case specifically includes: the starting positions are not overlapped, and the ending positions are overlapped; or the starting positions are overlapped, and the ending positions are not overlapped; alternatively, neither the start position nor the end position overlap. For the non-overlapping situation, the terminal divides the frequency domain resource of the PUSCH into a plurality of frequency domain resource subbands according to the pre-coding granularity and in a corresponding manner aligned with the pre-coding subbands, it should be noted that because the starting position and/or the ending position are/is not overlapped with the boundaries of the pre-coding subbands, when dividing the frequency domain resource of the PUSCH, the frequency domain resource of the middle position needs to be divided according to the pre-coding granularity and in a corresponding manner aligned with the pre-coding subbands, and for the frequency domain resource subbands of the starting position and/or the ending position, the division is smaller than the pre-coding granularity, and the PUSCH can be determined to transmit pre-coding subsequently only in an aligned manner.

Referring to fig. 2a, taking a case that the starting position and the ending position are not overlapped as an example, wherein 4 frequency domain resource subbands divided in the middle of the frequency domain resource of the PUSCH are aligned with the precoding subbands, precoding used by the 4 frequency domain resource subbands is determined according to the aligned precoding subbands, 2 frequency domain resource subbands at the starting position and the ending position are less than precoding granularity, and the used precoding is also determined according to the corresponding precoding subbands.

(3) When the frequency domain resources of the PUSCH include a plurality of discontinuous sub-frequency domain resources, and the starting position and the ending position of one or more sub-frequency domain resources overlap with the boundary of the pre-coding sub-band, for example, that the starting position and the ending position of a part of the sub-frequency domain resources possibly overlap with the boundary of the pre-coding sub-band, and the starting position and the ending position of another part of the sub-frequency domain resources do not overlap with the boundary of the pre-coding sub-band, the terminal divides each sub-frequency domain resource into a plurality of frequency domain resource sub-bands according to the pre-coding granularity in a corresponding manner aligned with the pre-coding sub-band, wherein the frequency domain resource sub-band of the starting position and the ending position of each sub-frequency domain resource is equal to the pre-coding granularity;

the PUSCH frequency domain resources dynamically scheduled by the network may be discontinuous, and for each discontinuous sub-frequency domain resource, it is also necessary to determine the transmission precoding corresponding to the frequency domain resource subband of each sub-frequency domain resource according to whether the starting position and the ending position of the sub-frequency domain resource overlap.

In this embodiment of the application, the starting position and the ending position of each sub-frequency domain resource are overlapped with the boundary of a precoding subband, and at this time, the frequency domain resource of the PUSCH is divided into a plurality of frequency domain resource subbands for each sub-frequency domain resource according to the precoding granularity by referring to the processing method in (1), the frequency domain resource subbands and the precoding subbands are aligned one to one, and it is only necessary to determine that the PUSCH transmits precoding in an aligned manner.

(4) Under the condition that the frequency domain resources of the PUSCH comprise a plurality of discontinuous sub-frequency domain resources, and the starting position and/or the ending position of one or more sub-frequency domain resources are not overlapped with the boundaries of the pre-coding sub-bands, the terminal divides each sub-frequency domain resource into a plurality of frequency domain resource sub-bands according to the pre-coding granularity and a corresponding mode aligned with the pre-coding sub-bands, wherein the frequency domain resource sub-bands of the starting position and/or the ending position of each sub-frequency domain resource are smaller than the pre-coding granularity;

in the embodiment of the present application, the starting position and/or the ending position of each sub-frequency domain resource does not overlap with the boundary of the precoding sub-band, and in this case, reference may be made to the processing manner in (2) above.

Specifically, referring to fig. 2b, a case that the starting position and the ending position of each sub-frequency domain resource are not overlapped is taken as an example, wherein the frequency domain resource of the PUSCH includes two discontinuous sub-frequency domain resources.

For each sub-frequency domain resource, the frequency domain resource sub-band divided in the middle is aligned with the pre-coding sub-band, the pre-coding used by the frequency domain resource sub-band is determined according to the aligned pre-coding sub-band, the frequency domain resource sub-bands at the starting position and the ending position are smaller than the pre-coding granularity, and the used pre-coding is also determined according to the corresponding pre-coding sub-band.

(5) Under the condition that the starting position and/or the ending position of the frequency domain resource of the PUSCH are/is not overlapped with the boundary of the pre-coding sub-band, the terminal divides the frequency domain resource of the PUSCH into a plurality of frequency domain resource sub-bands according to the pre-coding granularity, wherein the pre-coding sub-band corresponding to each frequency domain resource sub-band is determined according to the offset between the starting position of the frequency domain resource of the PUSCH and the boundary of the pre-coding sub-band, and the frequency domain resource sub-band at the ending position is smaller than or equal to the pre-coding granularity.

In the embodiment of the application, for the case that the starting position and/or the ending position do not overlap with the boundary of the precoding sub-band, the terminal performs frequency domain resource sub-band division according to the precoding granularity from the starting position, that is, it is ensured that the frequency domain resource sub-band of the starting position is equal to the precoding granularity, and the frequency domain resource sub-band of the ending position is less than or equal to the precoding granularity. When the transmission precoding is determined, the precoding subband corresponding to each frequency domain resource subband is determined according to the offset between the starting position of the frequency domain resource of the PUSCH and the boundary of the precoding subband.

Specifically, referring to fig. 2c, there is an offset between the starting position of the frequency domain resource and the boundary of the precoding sub-band, and after the frequency domain resource sub-bands are divided according to the precoding granularity, each frequency domain resource sub-band can find its corresponding transmission precoding according to the offset.

It should be noted that, for a special scenario, if the starting position of the frequency domain resource is exactly at the boundary position of two precoding sub-bands, when selecting to send precoding, it may be determined which precoding is specifically selected through network side configuration or protocol convention.

(6) Under the condition that the starting position and/or the ending position of one or more sub-frequency domain resources are not overlapped with the boundary of a pre-coding sub-band, the terminal divides each sub-frequency domain resource into a plurality of frequency domain resource sub-bands according to the pre-coding granularity, wherein the pre-coding sub-band corresponding to each frequency domain resource sub-band is determined according to the offset between the starting position of each sub-frequency domain resource and the boundary of the pre-coding sub-band, and the frequency domain resource sub-band at the ending position is smaller than or equal to the pre-coding granularity.

In this embodiment of the present application, for the case that PUSCH frequency domain resources dynamically scheduled by a network are discontinuous, and a starting position and/or an ending position of each sub-frequency domain resource is not overlapped with a boundary of a precoding subband, at this time, the processing manners (4) and (5) may be combined, and for each sub-frequency domain resource, a terminal performs frequency domain resource subband division according to precoding granularity from the starting position, that is, it is ensured that the frequency domain resource subband at the starting position is equal to the precoding granularity, and the frequency domain resource subband at the ending position is less than or equal to the precoding granularity. When the pre-coding is determined to be sent, the pre-coding sub-band corresponding to each frequency domain resource sub-band is determined according to the offset between the initial position of the sub-frequency domain resource and the boundary of the pre-coding sub-band.
