Description

PUSCH repeated transmission method and terminal equipment

Technical Field

The present invention relates to the field of communications, and in particular, to a PUSCH repeated transmission method, a terminal device, and a computer readable storage medium.

Background

In the prior art, downlink control information (Downlink Control Information, DCI) for scheduling a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) includes a sounding reference signal (Sounding Reference Signal, SRS) resource indication (Sounding Reference Signal Resource Indicator, SRS Resource Indicator, SRI) field and a transmit precoding matrix indication (Transmit Precoding Matrix Indicator, TPMI) field, and a terminal device obtains a single beam and a precoding matrix based on the indicated SRI and TPMI, so as to be used for PUSCH transmission. If PUSCH is configured for repeated transmissions, the transmit beams and precoding matrices used for different repeated transmissions are the same, both from the SRI domain and TPMI domain.

In order to further improve the reliability of uplink transmission by using multiple transmission and reception points (Transmission and Reception Point, TRP), new Radio (NR) introduces uplink retransmission based on multiple TRP, i.e. different retransmission can be sent to different TRP, as shown in fig. 1, which is a schematic diagram of PUSCH retransmission based on multiple TRP in one implementation. Since the channels corresponding to different TRPs are different, different repeated transmissions need to employ the transmission parameters (e.g., transmit beams and/or precoding matrices) corresponding to the channels for best transmission performance. However, in the existing protocol, the SRI domain and the TPMI domain can only obtain a single beam and a precoding matrix, and cannot match with respective channels of two TRPs at the same time, thereby affecting the performance of uplink transmission.

Detailed Description

The following description of the technical solutions according to the embodiments of the present invention will be given with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to fall within the scope of the invention.

The terms related to the embodiments of the present application will be briefly described as follows:

1. uplink codebook transmission and non-codebook transmission

When the terminal device transmits uplink data (physical uplink shared channel (Physical Uplink Shared Channel, PUSCH)), precoding processing is required for the uplink data to obtain uplink precoding gain. The precoding process is generally divided into two parts: analog domain processing and digital domain processing. Analog domain processing maps radio frequency signals onto physical antennas for transmitted analog signals, typically using beamforming. The digital domain processing is generally performed on a baseband for digital signals, and a precoding matrix is adopted to precode the digital signals, so that data of a transmission layer is mapped to a radio frequency port. Because of the limited number of radio frequency channels of the terminal device, two processing modes are generally adopted at the same time, namely, the digital signal is precoded, and then the analog signal is shaped by adopting wave beams. PUSCH transmissions are classified into codebook-based transmissions and non-codebook-based transmissions, depending on the precoding scheme.

In the uplink codebook-based precoding manner, the network side configures a set of sounding reference signal (Sounding Reference Signal, SRS) resources dedicated for codebook transmission for the terminal device. The terminal equipment sends SRS on a plurality of SRS resources in the set, the SRS on each SRS resource adopts different beams, the network side selects the best SRS resource from the SRS resources for obtaining uplink channel state indication (Channel State Information, CSI), and simultaneously indicates the resource index to the terminal equipment through SRS resource indication (Sounding Reference Signal Resource Indicator, SRS Resource Indicator, SRI), so that the terminal equipment adopts the corresponding beam of the SRS resource to carry out analog beamforming on data. Meanwhile, the network side indicates Rank Indicator (RI) and sends precoding matrix Indicator (Transmit Precoding Matrix Indicator, TPMI, also referred to as PMI) through downlink control information (Downlink Control Information, DCI), and the terminal device determines an uplink precoding matrix corresponding to the TPMI from the codebook according to the RI and the TPMI. Fig. 2 is a schematic diagram of a codebook-based PUSCH transmission in one implementation.

For some terminal devices supporting reciprocity of uplink and downlink channels, a precoding mode based on a non-codebook can be supported. The terminal equipment can obtain uplink channel information by utilizing the downlink channel information, so that uplink analog beam forming and/or digital precoding are performed, and at the moment, the network side does not need to indicate the related information of the precoding matrix any more, so that the cost of DCI can be reduced. Specifically, the network side firstly transmits a channel state information reference signal (Channel State Information Reference Signal, CSI Reference Signal, CSI-RS), so that the terminal device determines beams and precoding matrices of N layers based on the CSI-RS. The terminal device uses the N layer beams and the precoding matrix to transmit N single-port SRS resources (i.e., N SRS ports), where the N SRS resources are configured as one SRS resource set for non-codebook transmission. The network side receives the SRS resources, then measures, selects the best K SRS resources and indicates the corresponding SRI to the terminal equipment, and the terminal equipment determines the adopted transmission layer number, precoding matrix and analog beam according to the SRI. The indicated number of SRS resources is the number of transmission layers, and the precoding matrix and the analog beam adopted by the corresponding SRS resources are the precoding matrix and the beam adopted by the corresponding layer of data. At this time, RI and PMI need not be indicated in DCI. Fig. 3 is a schematic diagram of PUSCH transmission based on a non-codebook in one implementation.

2. Uplink repeated transmission

In order to improve the transmission reliability of PUSCH, new Radio (NR) introduces repeated transmission of PUSCH, that is, PUSCH carrying the same data is transmitted multiple times through different time-frequency resources/antennas/redundancy versions, so as to obtain diversity gain and reduce false detection probability (BLER). Specifically, the retransmission may be performed in different time slots, as shown in fig. 4, which is a schematic diagram of PUSCH retransmission based on time slots in one implementation. May be performed in different orthogonal frequency division multiplexing (Orthogonal Frequency Division Multiple, OFDM) symbols, as shown in fig. 5, which is a schematic diagram (intra-slot or cross-slot) of PUSCH retransmission based on OFDM symbols in one implementation. Or may be performed on multiple panels (antenna panels), as shown in fig. 6, which is a schematic diagram of PUSCH retransmission based on multiple TRP/panels in one implementation. For multi-slot or multi-symbol repeated transmission, one DCI may schedule multiple PUSCHs to transmit on consecutive multiple slots or multiple OFDM symbols, carrying the same data but employing different redundancy versions. At this time, the receiving ends of the different repeated transmissions may be the same transmission receiving point (Transmission and Reception Point, TRP) or different TRP. For multi-Panel repetition, PUSCHs carrying the same data are simultaneously and respectively transmitted on different Panels, and a receiving end can be the same TRP or different TRPs.

In the following, by way of example, the technical solution of the present invention is further described, as shown in fig. 8, which is a schematic diagram of an embodiment of a PUSCH retransmission method in the embodiment of the present invention, and may include:

801. the terminal equipment respectively determines transmission parameters used by different repeated transmissions of the PUSCH according to different parts of first information indicated by one SRI domain or one TPMI domain, wherein the one SRI domain and the one TPMI domain are contained in scheduling information of the PUSCH, and the transmission parameters comprise at least one of transmission layer number, precoding matrix, antenna port, transmitting wave beam and transmitting power.

802. And the terminal equipment respectively carries out repeated transmission of the PUSCH for multiple times according to the transmission parameters.

Optionally, the PUSCH scheduling information includes DCI for scheduling the PUSCH.

It can be understood that the terminal device determines the transmission parameters used for different repeated transmissions of PUSCH according to different parts in the first information indicated by one SRI field or one TPMI field. May include, but is not limited to, the following:

implementation 1:

the first information is two TPMI indicated by the one TPMI domain, each TPMI indicates a precoding matrix, and the terminal device determines first transmission parameters used for different repeated transmissions of the PUSCH according to the two TPMI, where the first transmission parameters include at least one of the transmission layer number, the precoding matrix and the transmission power.

1) Optionally, the two precoding matrices indicated by the two TPMI belong to the same codebook subset.

Optionally, the codebook subset is a full-correlation codebook subset, a partial-correlation codebook subset or an uncorrelated codebook subset.

Alternatively, the codebook subset may be indicated to the terminal by higher layer signaling.

Alternatively, the full correlation codebook subset may comprise a partial correlation codebook subset and a non-correlation codebook subset, and the partial correlation codebook subset may comprise the non-correlation codebook subset.

In such an implementation, the indication content of the one TPMI domain may be limited, thereby reducing the indication signaling overhead of the TPMI domain.

2) Optionally, the number of transmission layers (i.e. the number of columns of the matrix) corresponding to the precoding matrices indicated by the two TPMI is the same.

3) Optionally, the one TPMI field indicates both the transport layer number and the TPMI. I.e., the one TPMI field may indicate both the number of transport layers and the TPMI. The one TPMI field may also be referred to as precoding information and transport layer number indication field at this time.

4) Optionally, the two TPMI corresponding to different values of the one TPMI domain are notified to the terminal device through a higher layer signaling, or are pre-agreed by the terminal device and the network device. For example: is pre-defined by the terminal and the base station.

Alternatively, in an embodiment, each value of the one TPMI domain may correspond to one or two TPMI. For example, one part of the values of one TPMI field corresponds to one TPMI (0-7 in table 1 below), and the other part corresponds to two TPMI (8-15 in table below). When the one TPMI field indicates one TPMI, the precoding matrix indicated by the one TPMI is applied to all repeated transmissions of the PUSCH; when the one TPMI field indicates two TPMI, the precoding matrices indicated by the two TPMI are applied to different repeated transmissions of the PUSCH, for example, an odd number of repeated transmissions and an even number of repeated transmissions use different precoding matrices therein. The invention mainly aims at the condition that the value corresponds to two TPMI.

Alternatively, the higher layer signaling may be RRC signaling or MAC layer signaling. For example, assuming that the possible values of the one TPMI domain are 0-15, the TPMI corresponding to the different values may be as shown in table 1 below:

indication value of TPMI domain	Corresponding TPMI
0	0 (number of transmission layers 1)
1	1 (number of transmission layers 1)
2	2 (number of transmission layers 1)
3	3 (number of transmission layers 1)
4	4 (number of transmission layers 1)
5	5 (number of transmission layers 1)
6	0 (number of transmission layers is 2)
7	1 (number of transmission layers is 2)
8	{0,1} (number of transmission layers is 1)
9	{0,2} (number of layers of transmission is 1)
10	{0,3} (number of layers of transmission is 1)
11	{1,2} (number of layers of transmission is 1)
12	{1,3} (number of layers of transmission is 1)
13	{2,3} (number of layers of transmission is 1)
14	{4,5} (number of layers of transmission is 1)
15	{0,1} (number of layers of transmission is 2)

and the terminal equipment determines the transmission power or the transmission power scaling factor of the primary repeated transmission according to the TPMI corresponding to the primary repeated transmission of the PUSCH. The correspondence between different TPMI and transmission power (or transmission power scaling factor) may be pre-defined by the terminal and the network device, or may be pre-notified to the terminal device by the network device.

Optionally, the terminal device performs multiple repeated transmissions of the PUSCH according to the transmission parameter, and may include: and the terminal equipment performs repeated transmission of the PUSCH for a plurality of times according to the first transmission parameter, wherein the first transmission parameter comprises the transmission layer number and/or the precoding matrix.

For example, an odd number of repeated transmissions and an even number of repeated transmissions use different precoding matrices therein; alternatively, the first two repeated transmissions and the second two repeated transmissions use different precoding matrices, and so on.

I.e. the terminal device may use different parts of the first precoding matrix as the second precoding matrix used for different repeated transmissions of said PUSCH. Optionally, the terminal uses the number of columns of the second precoding matrix as the number of transmission layers of the PUSCH. For example, a first portion of the first precoding matrix is used as a precoding matrix for the odd number of repeated transmissions of the PUSCH; a second portion (different from the first portion) of the first precoding matrix is used as a precoding matrix for the even number of repeated transmissions of the PUSCH. The number of columns of the first part and the second part are the same, which indicates the number of transmission layers of the PUSCH. Specifically, at least three modes can be adopted:

1) The terminal equipment uses the front N/2 columns and the rear N/2 columns of the precoding matrix as the precoding matrices used for different repeated transmission of the PUSCH respectively. For example, the first N/2 columns of the first precoding matrix are used as partially repeated precoding matrices, and the last N/2 columns are used as other repeated precoding matrices.

Optionally, the number of transmission layers of the PUSCH is N/2.

Optionally, each column of the precoding matrix corresponds to one transmission layer.

Illustratively, if the PUSCH is a single layer transmission of 2 antenna ports, the one TPMI field may indicate one codeword from a codebook of a double layer transmission of 2 antenna ports, where the codeword has 2 columns of precoding vectors. Wherein the first and second columns of precoding vectors are used for different repeated transmissions, respectively. The method can be used for 4-port PUSCH transmission as well. For example, one precoding matrix indicated by the TPMI field is

The terminal device can

And

for different repeated transmissions.

2) The terminal equipment uses the first M/2 rows and the last M/2 rows of the precoding matrix as the precoding matrices used by different repeated transmissions of the PUSCH respectively. For example, the first M/2 rows of the first precoding matrix are used as partially repeated precoding matrices, and the later M/2 columns are used as other repeated precoding matrices.

Optionally, the number of transmission layers of the PUSCH is equal to the number of columns of the one precoding matrix.

Optionally, each row of the precoding matrix corresponds to one antenna port.

Illustratively, if the PUSCH is a single layer transmission of 2 antenna ports, the one TPMI domain may indicate one codeword from a codebook of single layer transmissions of 4 antenna ports, the codeword being a precoding matrix of 4 rows and 1 column. The precoding vectors obtained in the first two rows and the last two rows are respectively used for different repeated transmissions. The method can be equally used for PUSCH transmission for 4 port 2 layers. For example, one TPMI domain indicates a precoding matrix of

The precoding matrices obtained by the first 1 column in the first two rows and the last 1 column in the last two rows are respectively used for different repeated transmissions. For example, one precoding matrix indicated by the TPMI field is

for different repeated transmissions.

Optionally, the second transmission parameter may further include other parameters such as transmission power.

Alternatively, different portions of the one precoding matrix may correspond to different PUSCH transmission powers or transmission power scaling factors.

and the terminal equipment determines the transmission power or the transmission power scaling factor of the primary repeated transmission according to the partial precoding matrix of the one precoding matrix corresponding to the primary repeated transmission of the PUSCH. The correspondence between the different parts of the one precoding matrix and the transmission power (or the transmission power scaling factor) may be pre-defined by the terminal and the network device or pre-notified to the terminal device by the network device.

Optionally, the terminal device performs multiple repeated transmissions of the PUSCH according to the transmission parameter, and may include: and the terminal equipment performs repeated transmission of the PUSCH for a plurality of times according to the second transmission parameters, wherein the second transmission parameters comprise the transmission layer number and/or the precoding matrix.

For example, an odd number of repeated transmissions and an even number of repeated transmissions are precoded using different portions of the first precoding matrix; alternatively, the first and second duplicate transmissions are precoded using different portions of the first precoding matrix, and so on.

In the embodiment of the invention, the terminal equipment can obtain two precoding matrixes according to one precoding matrix indicated by one TPMI domain and is used for different PUSCH repeated transmissions, so that channels between different TRPs are respectively matched, and the performance of uplink multi-TRP diversity transmission is improved.

Implementation 3:

the first information is two SRIs indicated by one SRI field, each SRI indicates one SRS resource in different SRS resource sets, and the terminal device determines third transmission parameters used by different repeated transmissions of PUSCH according to the two SRIs, where the third transmission parameters include at least one of the transmission beam, the antenna port, and the transmission power.

It can be appreciated that each SRI indicates one of the different SRS resource sets, i.e., a first SRI of the two SRIs to indicate one of the first SRS resource set (referred to as a first SRS resource) and a second SRI to indicate one of the second SRS resource set (referred to as a second SRS resource). The first SRS resource set and the second SRS resource set may be preconfigured to the terminal device.

In one embodiment, when one value of one SRI field indicates two SRIs, one SRI may not indicate any SRS resource, which indicates that the corresponding SRS resource set is not used, where all repeated transmissions use another SRI to determine a transmit beam and/or an antenna port, so as to achieve the effect of dynamically switching between the two SRIs. Because different SRIs correspond to different TRP (time-resolved power) receiving, dynamic switching between two TRP receiving points can be supported, and the current best TRP is flexibly selected as the receiving point, so that better transmission performance is achieved.

Optionally, the embodiment of the present invention may be used for PUSCH transmission based on a Codebook, that is, the foregoing first SRS resource set and the second SRS resource set are SRS resource sets for uplink Codebook transmission (that is, a user parameter of the SRS resource set is configured as a Codebook).

Optionally, the terminal device may determine a transmit beam, an antenna port, or a transmit power used for different repeated transmissions of the PUSCH by:

1) And the terminal equipment takes the sending beam used by SRS resources indicated by SRI corresponding to the primary repeated transmission of the PUSCH as the sending beam of the primary repeated transmission.

It can be appreciated that each repeated transmission of the PUSCH uses the same transmit beam as the SRS resource indicated by the SRI corresponding to the repeated transmission. For example, the partial repeated transmissions of PUSCH correspond to the first SRI, and these repeated transmissions use the same transmit beam as the first SRS resource indicated by the first SRI; the other repeated transmissions correspond to the second SRI, and the repeated transmissions use the same transmit beam as the second SRS resources indicated by the second SRI. In the embodiment of the present invention, the transmission beam may also be referred to as a spatial domain transmission filter or a spatial filter.

2) And the terminal equipment takes the port number of SRS resources indicated by SRI corresponding to the one-time repeated transmission of the PUSCH as the port number of the one-time repeated transmission.

It can be appreciated that the number of antenna ports used for each repeated transmission of the PUSCH is equal to the number of ports of SRS resources indicated by the SRI to which the repeated transmission corresponds. For example, if the partial repeated transmissions of PUSCH correspond to the first SRI, then the number of antenna ports used for these repeated transmissions is equal to the number of ports of the first SRS resource; and if the other repeated transmissions correspond to the second SRI, the number of antenna ports used by the repeated transmissions is equal to the number of ports of the second SRS resource. The terminal may further determine the codebook used based on the number of antenna ports.

3) And at least one value of the SRI domain corresponds to two groups of PUSCH power control parameters, and the two groups of PUSCH power control parameters are respectively used for determining the transmission power of different repeated transmissions of the PUSCH. Specifically, at least one value of the one SRI field corresponds to two sets of PUSCH power control parameters, and the terminal device determines, from the two sets of PUSCH power control parameters, a PUSCH power control parameter used for the one repetition transmission according to an SRI corresponding to the one repetition transmission of the PUSCH; and determining the sending power of the repeated transmission according to the PUSCH power control parameter. I.e. the two sets of PUSCH power control parameters are used for determining the transmit power used for different repeated transmissions of the PUSCH, respectively.

Two possible configuration scenarios are considered below:

i. a partial value of one SRI field may indicate one SRI and other values may indicate two SRIs.

In one embodiment, if a certain value of one SRI field indicates two SRIs, the value corresponds to two sets of PUSCH power control parameters, which are used to determine the transmission power of different repeated transmissions, respectively. If a certain value of an SRI field indicates an SRI, the value corresponds to a set of PUSCH power control parameters, and all repeated transmissions use the set of power control parameters to determine the transmit power.

In another embodiment, if each value of one SRI field corresponds to two sets of PUSCH power control parameters, when a certain value indicates two SRIs, the two sets of PUSCH power control parameters are respectively used to determine the transmission power of different repeated transmissions; when a certain value indicates an SRI, the terminal uses one of the two sets of PUSCH power control parameters to determine the transmit power of all repeated transmissions, e.g., the first set of power control parameters therein. Under some special configurations, for example, when a certain value indicates two SRIs but one SRI does not indicate any SRS resource, the terminal device determines the transmission power of all the repeated transmissions using the PUSCH power control parameter corresponding to the other SRI.

For example, the value range of the one SRI field is 0-7, where the values 4-7 indicate two SRIs, and each value of these values corresponds to two sets of PUSCH power control parameters, and the terminal device determines the power control parameters used by the repeated transmission according to the SRIs corresponding to the repeated transmission. If the partial repeated transmissions of the PUSCH correspond to the first SRI therein, the transmit powers of these repeated transmissions are determined according to a first set of power control parameters; if the partial repeated transmissions of the PUSCH correspond to the second SRI therein, the transmit power of these repeated transmissions is determined according to a second set of power control parameters.

ii. All values of one SRI field may indicate one SRI or both SRIs, whichever is used depends on the configuration of the higher layer signaling. If the higher layer signaling configures one SRI domain to only indicate one SRI, each value of the SRI domain corresponds to a group of PUSCH power control parameters; if one SRI field is configured by the higher layer signaling to indicate two SRIs, each value of the SRI field may correspond to two sets of PUSCH power control parameters. The terminal equipment determines which group of power control parameters is the power control parameters used by the repeated transmission according to the SRI corresponding to the repeated transmission.

In an embodiment, two sets of PUSCH power control parameters corresponding to different values of one SRI domain may be configured to the terminal device through higher layer signaling.

Optionally, the terminal device performs multiple repeated transmissions of the PUSCH according to the transmission parameter, and may include: and the terminal equipment respectively carries out repeated transmission of the PUSCH for multiple times according to the third transmission parameter.

For example, the odd and even number of repeated transmissions use different transmit beams and/or antenna ports; alternatively, the first and second duplicate transmissions use different transmit beams and/or antenna ports, and so on.

In the embodiment of the invention, the terminal equipment obtains two groups of sending beams and/or antenna ports according to two SRIs indicated by one SRI domain and is used for different PUSCH repeated transmission, so that channels between different TRPs are respectively matched, and the performance of uplink multi-TRP diversity transmission is improved.

Implementation 4:

and the terminal equipment respectively determines third transmission parameters used by different repeated transmissions of the PUSCH according to the two SRI sets, wherein the third transmission parameters comprise at least one of the sending beam, the antenna port, the transmission layer number and the sending power.

Optionally, the two SRI sets include a first SRI set indicating one or more single-port SRS resources in a third SRS resource set and a second SRI set indicating one or more single-port SRS resources in a fourth SRS resource set. That is, a first set of two SRI sets indicates one or more single-port SRS resources in a third SRS resource set, and a second set indicates one or more single-port SRS resources in a fourth SRS resource set. The third SRS resource set and the fourth SRS resource set may be preconfigured to the terminal device.

In some embodiments, one SRI set may not include any SRI, i.e. no SRS resource is indicated, which indicates that the corresponding SRS resource set is not used, and at this time, all repeated transmissions use another SRI set to determine the transmission parameters, so as to achieve the effect of dynamically switching between the two SRI sets. Because different SRI sets correspond to different TRP (radio resource control) receiving points, dynamic switching between two TRP receiving points can be supported, and the current best TRP is flexibly selected as the receiving point, so that better transmission performance is achieved.

Alternatively, one or more SRIs may be included in each SRI set, and the number of SRIs included in the two SRI sets is the same.

Optionally, the embodiment of the present invention may be used for PUSCH transmission based on a codebook, that is, the aforementioned third SRS resource set and fourth SRS resource set are SRS resource sets for uplink non-codebook transmission (the user parameter of the sets is configured as a non codebook).

Alternatively, one or more SRIs may be included in each SRI set, and the number of SRIs included in both SRI sets is the same.

Optionally, at least one value of the one SRI field respectively corresponds to two SRI sets, and the two SRI sets are notified to the terminal device through a high-layer signaling, or are pre-agreed by the terminal device and the network device.

It will be appreciated that the two SRI sets corresponding to different values of the one SRI domain may be signaled to the terminal device by the MAC layer, or may be pre-defined by the terminal device and the network device (e.g. base station). For example, the network device may notify the terminal of the SRI set corresponding to each value of the SRI domain through the following table, or the terminal and the network device may have a predetermined correspondence (one SRI set in one of the brackets) as follows table. In some embodiments, different values may correspond to different numbers of SRI sets; in other embodiments, all values correspond to the same number of SRI sets, and whether the number of SRI sets is 1 or 2 is preconfigured by higher layer signaling.

TABLE 3 Table 3

Optionally, the determining, by the terminal device, a transmission beam, an antenna port, a transmission layer number, or a transmission power used for different repeated transmissions of the PUSCH may be one of the following manners:

1) Optionally, the terminal device uses the number of SRIs included in each SRI set as the number of transmission layers used for different repeated transmissions of the PUSCH. The number of SRIs contained in each SRI set is the number of transmission layers of the PUSCH. Further, the number of SRIs does not exceed 2.

2) Optionally, the terminal device uses the SRI set corresponding to the PUSCH one-time repeated transmission, and the indicated transmission beams used by each SRS resource respectively as the transmission beams used by each transmission layer of the one-time repeated transmission.

It can be appreciated that each transmission layer of each retransmission of the PUSCH uses the same transmit beam with each SRS resource indicated by the SRI set corresponding to the retransmission. For example, each repeated transmission of PUSCH comprises two transmission layers, wherein a partial repeated transmission corresponds to a first set of SRIs indicating two single-port SRS resources, the first transmission layer of these repeated transmissions using the same transmit beam as the first SRS resource therein and the second transmission layer using the same transmit beam as the second SRS resource therein. The same method is used for repeated transmissions corresponding to the second set of SRIs.

3) Optionally, the terminal device uses the SRI set corresponding to the one repetition transmission of the PUSCH and the antenna ports of the indicated one or more SRS resources as the antenna ports of each transmission layer for transmitting the one repetition transmission.

It can be appreciated that each repeated transmission of the PUSCH uses the same antenna port as the SRS resource indicated by the SRI set corresponding to the repeated transmission. For example, each repeated transmission of PUSCH includes two transmission layers, where a portion of the repeated transmissions correspond to a first set of SRIs indicating two single-port SRS resources, and each of these repeated transmissions uses the same antenna port as the two SRS resources (i.e., a first transmission layer uses the same antenna port as the first SRS resource and a second transmission layer uses the same antenna port as the second SRS resource). The same method is used for repeated transmissions corresponding to the second set of SRIs.

4) At least one value of the one SRI domain corresponds to two groups of PUSCH power control parameters, and the terminal equipment determines the PUSCH power control parameters used for the primary repeated transmission from the two groups of PUSCH power control parameters according to the SRI set corresponding to the primary repeated transmission of the PUSCH; and determining the sending power of the repeated transmission according to the PUSCH power control parameter. I.e. the two sets of PUSCH power control parameters are used for determining the transmit power of different repeated transmissions of the PUSCH, respectively. Specifically, the following embodiments may be adopted:

i. In one embodiment, if a certain value of one SRI field indicates two SRI sets, the value corresponds to two sets of PUSCH power control parameters, which are used to determine the transmission power of different repeated transmissions, respectively. If a certain value of an SRI field indicates an SRI set, the value corresponds to a set of PUSCH power control parameters, and all repeated transmissions use the set of power control parameters to determine the transmit power. For example, the value range of the one SRI field is 0-7, where the values 4-7 indicate two SRI sets, and each value of these values corresponds to two sets of PUSCH power control parameters, and the terminal device determines the power control parameters used by the repeated transmission according to the SRI set corresponding to the repeated transmission. If the partial repeated transmissions of the PUSCH correspond to the first set of SRIs therein, the transmit powers of these repeated transmissions are determined according to a first set of power control parameters; if the partial repeated transmissions of the PUSCH correspond to the second set of SRIs therein, the transmit power of these repeated transmissions is determined according to a second set of power control parameters.

ii. In another embodiment, if each value of one SRI field corresponds to two sets of PUSCH power control parameters, when a certain value indicates two SRI sets, the two sets of PUSCH power control parameters are respectively used to determine the transmission power of different repeated transmissions; when a certain value indicates one SRI set, the terminal device uses one of the two sets of PUSCH power control parameters to determine the transmission power of all repeated transmissions, e.g. the first set of power control parameters therein. Under some special configurations, for example, when a certain value indicates two SRI sets but one of the SRI sets does not indicate any SRIs, the terminal device uses PUSCH power control parameters corresponding to the other SRI set to determine the transmission power of all repeated transmissions.

in another embodiment, all values of one SRI field may indicate one set of SRIs, or both sets of SRIs, whichever is employed depends on the configuration of the higher layer signaling. If the SRI domain is configured by the high-layer signaling, only one SRI set is indicated, each value of the one SRI domain corresponds to a group of PUSCH power control parameters; if the higher layer signaling configures the SRI field to indicate two SRI sets, each value of the one SRI field may correspond to two sets of PUSCH power control parameters. The terminal equipment determines which group of power control parameters is the power control parameters used by the repeated transmission according to the SRI set corresponding to the repeated transmission.

Optionally, two sets of PUSCH power control parameters corresponding to different values of one SRI domain may be configured to the terminal device through higher layer signaling.

Optionally, the terminal device performs multiple repeated transmissions of the PUSCH according to the transmission parameter, and may include: and the terminal equipment respectively carries out repeated transmission of the PUSCH for multiple times according to the fourth transmission parameter.

For example, the odd number of repeated transmissions and the even number of repeated transmissions use different transmission parameters; alternatively, the first two repeated transmissions and the second two repeated transmissions use different transmission parameters, and so on.

In the embodiment of the invention, the terminal equipment can obtain two groups of transmission parameters according to two SRI sets indicated by one SRI domain for different PUSCH repeated transmission, so that channels between different TRPs are respectively matched, and the performance of uplink multi-TRP diversity transmission is improved.

In the above-mentioned embodiment of the present invention, by redefining the existing SRI domain or TPMI domain, on the premise of not increasing DCI signaling overhead, transmission parameters used for repeated transmission of PUSCH are indicated respectively, and different transmission parameters may be adopted for different repeated transmissions, so as to ensure that the transmission parameters of each repeated transmission are matched with corresponding channels, and achieve better transmission performance. The terminal equipment can obtain two groups of transmission parameters according to one SRI domain or TPMI domain for different repeated transmission, so that the channels between different TRPs are respectively matched, and the performance of uplink multi-TRP diversity transmission is improved.

Corresponding to the above-mentioned at least one method applied to the embodiment of the terminal device, the embodiment of the present application further provides one or more terminal devices. The terminal device of the embodiment of the application may implement any implementation manner of the above method. As shown in fig. 9, which is a schematic diagram of an embodiment of a terminal device in an embodiment of the present invention, the terminal device is illustrated by using a mobile phone as an example, and may include: radio Frequency (RF) circuitry 910, memory 920, input unit 930, display unit 940, sensor 950, audio circuitry 960, wireless fidelity (wireless fidelity, wiFi) module 970, processor 980, and power source 990.

The following describes the components of the mobile phone in detail with reference to fig. 9:

Typically, the RF circuitry 910 includes, but is not limited to, an antenna, at least one amplifier, a transceiver, a coupler, a low noise amplifier (low noise amplifier, LNA), a duplexer, and the like. In addition, the RF circuitry 910 may also communicate with networks and other devices via wireless communications.

Alternatively, the touch panel 931 may include two parts of a touch detection device and a touch controller. The touch detection device detects the touch azimuth of a user, detects a signal brought by touch operation and transmits the signal to the touch controller; the touch controller receives touch information from the touch detection device and converts it into touch point coordinates, which are then sent to the processor 980, and can receive commands from the processor 980 and execute them. In addition, the touch panel 931 may be implemented in various types such as resistive, capacitive, infrared, and surface acoustic wave. The input unit 930 may include other input devices 932 in addition to the touch panel 931. In particular, other input devices 932 may include, but are not limited to, one or more of a physical keyboard, function keys (e.g., volume control keys, switch keys, etc.), a trackball, mouse, joystick, etc.

The display unit 940 may include a display panel 941, and alternatively, the display panel 941 may be configured in the form of a liquid crystal display (liquid crystal display, LCD), an organic light-Emitting diode (OLED), or the like. Further, the touch panel 931 may overlay the display panel 941, and when the touch panel 931 detects a touch operation thereon or thereabout, the touch operation is transferred to the processor 980 to determine a type of touch event, and then the processor 980 provides a corresponding visual output on the display panel 941 according to the type of touch event. Although in fig. 9, the touch panel 931 and the display panel 941 are implemented as two separate components for the input and output functions of the mobile phone, in some embodiments, the touch panel 931 may be integrated with the display panel 941 to implement the input and output functions of the mobile phone.

The handset may also include at least one sensor 950, such as a light sensor, motion sensor, and other sensors. Specifically, the light sensor may include an ambient light sensor and a proximity sensor, wherein the ambient light sensor may adjust the brightness of the display panel 941 according to the brightness of ambient light, and the proximity sensor may turn off the display panel 941 and/or the backlight when the mobile phone moves to the ear. As one of the motion sensors, the accelerometer sensor can detect the acceleration in all directions (generally three axes), and can detect the gravity and direction when stationary, and can be used for applications of recognizing the gesture of a mobile phone (such as horizontal and vertical screen switching, related games, magnetometer gesture calibration), vibration recognition related functions (such as pedometer and knocking), and the like; other sensors such as gyroscopes, barometers, hygrometers, thermometers, infrared sensors, etc. that may also be configured with the handset are not described in detail herein.

Audio circuitry 960, speaker 961, microphone 962 may provide an audio interface between a user and a cell phone. Audio circuit 960 may transmit the received electrical signal converted from audio data to speaker 961, where it is converted to a sound signal by speaker 961 for output; on the other hand, microphone 962 converts the collected sound signals into electrical signals, which are received by audio circuit 960 and converted into audio data, which are processed by audio data output processor 980 for transmission to, for example, another cell phone via RF circuit 910 or for output to memory 920 for further processing.

WiFi belongs to a short-distance wireless transmission technology, and a mobile phone can help a user to send and receive emails, browse webpages, access streaming media and the like through a WiFi module 970, so that wireless broadband Internet access is provided for the user. Although fig. 9 shows a WiFi module 970, it is understood that it does not belong to the necessary constitution of the handset, and can be omitted entirely as needed within the scope of not changing the essence of the invention.

The processor 980 is a control center of the handset, connecting various parts of the entire handset using various interfaces and lines, performing various functions and processing data of the handset by running or executing software programs and/or modules stored in the memory 920, and invoking data stored in the memory 920, thereby performing overall monitoring of the handset. Optionally, processor 980 may include one or more processing units; preferably, the processor 980 may integrate an application processor with a modem processor, wherein the application processor primarily handles operating systems, user interfaces, applications programs, etc., and the modem processor primarily handles wireless communications. It will be appreciated that the modem processor described above may not be integrated into the processor 980.

The handset further includes a power supply 990 (e.g., a battery) for powering the various components, which may be logically connected to the processor 980 by a power management system, such as for performing charge, discharge, and power management functions via the power management system. Although not shown, the mobile phone may further include a camera, a bluetooth module, etc., which will not be described herein.
