Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

Referring to fig. 1, a schematic diagram of a system architecture according to an embodiment of the present application is shown. The system architecture may include: a terminal device 10 and a network device 20.

The number of terminal devices 10 is typically plural, and one or more terminal devices 10 may be distributed within a cell managed by each network device 20. The terminal device 10 may include various handheld devices, in-vehicle devices, wearable devices, computing devices, or other processing devices connected to a wireless modem, as well as various forms of User Equipment (UE), mobile Station (MS), and the like, having wireless communication capabilities. For convenience of description, in the embodiment of the present application, the above-mentioned devices are collectively referred to as a terminal device.

The network device 20 is a means deployed in the access network to provide wireless communication functionality for the terminal device 10. The network device 20 may include various forms of macro base stations, micro base stations, relay stations, access points, and the like. The names of network device-capable devices may vary in systems employing different radio access technologies, for example in 5G NR systems, called gndeb or gNB. As communication technology evolves, the name "network device" may change. For convenience of description, in the embodiment of the present application, the above-mentioned devices for providing the terminal device 10 with the wireless communication function are collectively referred to as a network device.

The "5G NR system" in the embodiments of the present disclosure may also be referred to as a 5G system or an NR system, but a person skilled in the art may understand the meaning thereof. The technical scheme described in the embodiment of the disclosure can be applied to a 5G NR system and also can be applied to a subsequent evolution system of the 5G NR system.

SRS: the method is used for uplink channel information acquisition, downlink channel information acquisition and uplink beam management. The NR system manages and configures SRS in the manner of SRS resource set. Depending on the use, the network device may configure the terminal device with multiple SRS resource sets, each SRS resource set including one or more SRS resources, each SRS resource containing 1, 2, or 4 ports. The configuration information of each SRS resource set includes a usage indication, which may be configured as "beam management", "codebook", "non-codebook" or "antenna switching", and is used for uplink beam management, uplink channel information acquisition based on a codebook, uplink channel information acquisition based on a non-codebook uplink transmission scheme, and downlink channel information acquisition based on SRS antenna switching, respectively.

Codebook transmission scheme

The uplink transmission scheme based on the codebook is a multi-antenna transmission technology for determining an uplink transmission precoding matrix based on a fixed codebook. The uplink transmission scheme based on the codebook in the NR system has the following flow:

the UE transmits an SRS for codebook-based uplink transmission scheme CSI (Channel State Information ) acquisition to the base station.

The base station performs uplink channel detection according to SRS sent by the UE, performs resource scheduling on the UE, determines SRS resources corresponding to uplink transmission, the number of layers of uplink transmission and a precoding matrix, further determines MCS (Modulation and Coding Scheme, modulation coding mode) registration of uplink transmission according to the precoding matrix and channel information, and then notifies the UE of PUSCH resource allocation and corresponding MCS, transmission precoding matrix indication (Transmitted Precoding Matrix Indicator, TPMI), the number of transmission layers and corresponding SRS resource indication.

The UE carries out modulation coding on the data according to the MCS indicated by the base station, determines a precoding matrix and a transmission layer number used during data transmission by utilizing the indicated SRI, the indicated TPMI and the indicated transmission layer number, and further carries out precoding and transmission on the data, and a demodulation pilot signal of the PUSCH and the data of the PUSCH adopt the same precoding mode.

And the base station estimates an uplink channel according to the demodulation pilot frequency channel and performs data detection.

Before R16 (Release 16) and R16, the NR system allows the base station to configure at most one SRS resource set for UE to acquire CSI based on codebook uplink, where at most two SRS resources may be configured in the SRS resource set, and the two SRS resources include the same SRS antenna port number. Since the enhancement of PUSCH based on MTRP is introduced in R17 (Release 17), starting from R17, the NR system allows the base station to configure at most two SRS resource sets for UE to acquire CSI based on codebook uplink, and there is no limitation on whether the number of resources that can be contained in the two resource sets is the same in R17. The base station indicates SRS resources corresponding to the PUSCH to the UE through SRI field (SRI domain) in the DCI, so as to assist the UE to determine antennas, analog beamforming and the like used for PUSCH transmission according to the SRS resources selected by the base station. Since the number of SRS resources configured by the base station for different uplink transmission schemes may be different, determining the number of bits corresponding to the SRI based on the uplink transmission scheme may reduce the overhead of the SRI. The size of the SRI information and the size of the SRS resource for indicating the PUSCH in the uplink scheduling information depend on the number of SRS resources configured for the uplink transmission mode corresponding to the PUSCH. When the base station configures only one SRS resource for one uplink transmission mode of the UE, the PUSCH under the uplink transmission scheme corresponds to the SRS resource, and the SRI information domain does not exist in the uplink scheduling information.

Transmission scheme for non-codebook

The non-codebook transmission scheme is different from the codebook-based transmission scheme in that its precoding is not limited to a limited candidate set based on a fixed codebook, and the UE determines an uplink precoding matrix based on channel reciprocity. If the channel reciprocity is good enough, the UE can obtain better uplink precoding, and compared with the codebook-based transmission scheme, the overhead of precoding indication can be saved, and better performance can be obtained. The uplink transmission scheme based on the codebook in the NR system has the following flow:

the UE measures the downlink reference signals, obtains candidate uplink precoding matrixes, and sends the precoding matrixes to the base station after precoding SRS used for a non-codebook uplink transmission scheme by using the uplink precoding matrixes.

And the base station performs uplink channel detection according to the SRS sent by the UE, performs resource scheduling on the UE, determines SRS resources corresponding to uplink transmission, MCS levels of the uplink transmission and the like, and informs the UE. Wherein, the SRS resource corresponding to the uplink transmission is indicated to the UE through the SRI.

And the UE carries out modulation coding on the data according to the MCS sent by the base station, determines the precoding and the transmission layer number of the data by utilizing the SRI, and carries out data transmission after the precoding on the data. The same precoding mode is adopted for the PUSCH demodulation pilot frequency and the data of the PUSCH under the non-codebook uplink transmission scheme.

And the base station estimates an uplink channel according to the demodulation pilot frequency signal and performs data detection.

In the R16 and the version before R16, for the non-codebook uplink transmission scheme, the base station may configure 1 SRS resource set for uplink CSI acquisition for the UE, where 1-4 SRS resources are included, and each SRS resource includes 1 SRS port. The SRI may indicate one or more SRS resources for use in the determination of PUSCH precoding. The SRS resource number indicated by the SRI is the stream number of the PUSCH transmission, and the transmission layer of the PUSCH corresponds to the SRS resource indicated by the SRI one by one.

Indication of SRI in downlink control channel:

when the network side schedules the PUSCH through the DCI0-1 or the DCI0-2, the corresponding SRS resource is indicated through the SRI domain. When the network side configures uplink transmission as codebook transmission, the size of SRI domain is [ log ] ₂ (N _SRS )]bit, where N _SRS For the number of SRS resources, if the number of SRS resources configured at the network side is 1, there will be no SRI field in DCI0-1 or DCI 0-2. When the network side configures uplink transmission to be non-codebook transmission, the size of SRI domain is as followsWherein L is _max For the maximum number of transmission layers configurable by the terminal equipment, k is 1 to the maximum number of transmission layers configurable by the terminal, if the number of SRS resources configured by the network side is 1, no SRI domain exists in DCI0-1 or DCI 0-2.

Uplink power control and uplink power control indication:

the uplink power control mainly comprises an open loop power control part, a closed loop power control part and other adjustment amounts. The open loop parameters of the PUSCH power control mainly comprise P0 and alpha values, PL is path loss estimation, and the path loss estimation is estimated through a downlink reference signal. alpha is a partial path loss compensation factor, and the value range is 0 to 1. f (l) is closed loop power control, and is dynamically indicated by DCI. Wherein the open loop parameters P0 and alpha of the PUSCH power control are configured in pairs, which is called P0-PUSCH-alpha set.

T38.331, wherein SRI-PUSCH-PowerControlId is obtained from SRI field in DCI, when DCI0-1 and DCI0-2 perform PUSCH scheduling, if there is SRI field, a unique SRI-PUSCH-PowerControlId value can be obtained, and according to this ID value, a unique PUSCH-PatholossReference RS-Id and P0-PUSCH-AlphaSetId can be obtained. In the R16 and R16 previous versions, if the SRI field does not exist, then P0 and alpha take the P0 and alpha values in the first P0-PUSCH-alpha set. The path loss estimation is based on RS (Reference Signal) resources corresponding to a pusch-pathassreference RS-Id of 0.

In R17, since the repeated transmission of PUSCH based on MTRP is introduced, there are two SRS resource sets at this time, when there is only one SRS resource in both SRS resource sets, there may be no SRI field in the PDCCH at this time, and at this time, it is required to explicitly define the open loop power control parameter of PUSCH when the PUSCH is transmitted through the SRS resources in both SRS resource sets.

Referring to fig. 2, a flowchart of a method for determining a power control parameter according to an embodiment of the present application is shown, and the method may be applied to the system architecture shown in fig. 1. The method comprises the following steps.

In step 210, the network device configures at least two SRS resource sets for the terminal device, where each SRS resource set corresponds to a power control parameter set, and each power control parameter set includes at least one group of power control parameters.

The network device configures a first SRS resource set and a second SRS resource set for the terminal device.

The first set of SRS resources includes at least one SRS resource. Illustratively, the first SRS resource set includes at least first SRS resources.

The first SRS resource set corresponds to a first power control parameter set including at least one set of power control parameters corresponding to the first SRS resource set. The first set of power control parameters illustratively includes a first set of power control parameters. The set of power control parameters includes an open loop power control portion, a closed loop power control portion, and other adjustment amounts, wherein the open loop power control portion includes P0, an alpha value, and a reference signal for path loss estimation.

In an alternative embodiment, the target power control parameter corresponding to the first SRS resource set is obtained from the first power control parameter set.

The second set of SRS resources includes at least one SRS resource. Illustratively, the second SRS resource set includes at least the second SRS resource.

The second SRS resource set corresponds to a second power control parameter set including at least one set of power control parameters corresponding to the second SRS resource set. The second set of power control parameters illustratively includes a second set of power control parameters.

For example, the power control parameters in the first power control parameter set and the second power control parameter set may be the same or different. For example, the first set of power control parameters may be the same as the second set of power control parameters, or the first set of power control parameters may be different from the second set of power control parameters.

In an alternative embodiment, the target power control parameter corresponding to the second SRS resource set is obtained from the second power control parameter set.

The foregoing "first" and "second" are used for distinguishing two identical nouns only, and do not denote a sequential relationship. For example, any one set of power control parameters in the first set of power control parameters may be referred to as a first set of power control parameters.

For example, in the embodiment of the present application, only the network device configures the first SRS resource set and the second SRS resource set for the terminal device to exemplify, and of course, the network device may also configure more SRS resource sets for the terminal device, for example, configure three SRS resource sets, four SRS resource sets, or more. For the case of configuring more SRS resource sets, the method for determining the target power control parameter by the terminal device may be similar to the method for determining the power control parameter of the first SRS resource set or the method for determining the power control parameter of the second SRS resource set provided in the embodiments of the present application.

Illustratively, the network device transmits the configured at least two SRS resource sets to the terminal device.

Step 220, the terminal device receives at least two SRS resource sets configured by the network device, where each SRS resource set corresponds to at least one set of power control parameters.

In step 230, the terminal device determines the target power control parameter in at least two power control parameter sets corresponding to at least two SRS resource sets.

The terminal device may determine, according to at least one of the SRI domain and the agreed rule, a target power control parameter from at least two power control parameter sets corresponding to at least two SRS resource sets.

Wherein, the rule is a rule agreed in the communication protocol. The SRI field is included in DCI transmitted by the network device.

Illustratively, the rule may be to determine the z-th group of power control parameters in the power control parameter set as the target power control parameter, and z may be any positive integer, for example, z takes 1.

For example, a target power control parameter for a set of SRS resources (e.g., a first set of SRS resources) may be determined from a set of power control parameters corresponding to the set of SRS resources (e.g., the first set of SRS resources) based on the agreed rule. The target power control parameters for the SRS resource set (e.g., the first SRS resource set) may also be determined from power control parameter sets corresponding to other SRS resource sets (e.g., the second SRS resource set) based on the agreed rule.

The target power control parameter is used for setting a power value of the PUSCH through the target SRS resource. For example, when the network device indicates that PUSCH is transmitted through a plurality of SRS resources on a plurality of SRS resource sets, the terminal device needs to determine a target power control parameter corresponding to each SRS resource set respectively, so as to use the SRS resources specified by the network device in the SRS resource set to perform PUSCH transmission according to the target power control parameter.

The target power control parameters include at least one set of power control parameters. Illustratively, the number of target power control parameters depends on the number of SRS resource sets used by PUSCH. For example, when the number of SRS resource sets used by PUSCH is 1, the target power control parameter includes one set of power control parameters, and when the number of SRS resource sets used by PUSCH is 2, the target power control parameter includes two sets of power control parameters.

For example, the terminal device determines, according to DCI sent by the network device, an SRS resource set (target SRS resource set) used for the current PUSCH transmission and an SRS resource (target SRS resource) in the SRS resource set, and determines a set of power control parameters (target power control parameters) from at least one set of power control parameters (power control parameter set) corresponding to the target SRS resource set.

In step 240, the terminal device performs PUSCH transmission through a target SRS resource according to the target power control parameter, where the target SRS resource includes SRS resources in at least one SRS resource set of the at least two SRS resource sets.

And the terminal equipment sets a power value when carrying out PUSCH transmission through the target SRS resources in the corresponding target SRS resource set according to the target power control parameter, and carries out PUSCH transmission.

In step 250, the network device receives PUSCH transmission performed by the terminal device through the target SRS resource according to the target power control parameter, where the target power control parameter is determined by the terminal device in at least one set of power control parameters, and the target SRS resource includes SRS resources in at least one SRS resource set of at least two SRS resource sets.

In summary, in the method provided in this embodiment, after receiving at least two SRS resource sets configured by the network device, a set of target power control parameters is determined from at least one set of power control parameters corresponding to the SRS resource sets, and PUSCH transmission is performed on the corresponding target SRS resources according to the target power control parameters. When PUSCH transmission is performed based on MTRP, the terminal device can determine the power control parameters which are finally used for at least one group of power control parameters corresponding to the two SRS resource sets respectively, and further perform PUSCH transmission on SRS resources according to the power control parameters.

For example, taking an example that an SRS resource set configured by a network device includes a first SRS resource set and a second SRS resource set, a method for determining a power control parameter provided in the present application is described.

Different determining modes aiming at target power control parameters, different SRS resource quantity in SRS resource sets configured by network equipment, different SRS resource sets indicated by DCI and used for PUSCH, different transmission times of PUSCH indicated by DCI can be obtained, and various embodiments can be obtained.

1. The determination mode of the target power control parameter comprises the following steps:

(1.1) determining a target power control parameter according to the SRI domain;

(1.2) determining target power control parameters according to the agreed rules;

(1.3) determining target power control parameters according to the SRI domain and the constraint rules.

In the related art, when the number of SRS resources contained in the SRS resource set is greater than 1, an SRI domain corresponding to the SRS resource set exists in the DCI; when the number of SRS resources contained in the SRS resource set is equal to 1, an SRI domain corresponding to the SRS resource set does not exist in the DCI.

In this embodiment of the present application, when the number of SRS resources included in the SRS resource set is equal to 1, there may be an SRI domain corresponding to the SRS resource set in DCI, or there may not be an SRI domain corresponding to the SRS resource set. When the SRI domain corresponding to the SRS resource set exists in the DCI, the terminal equipment determines the target power control parameter based on the SRI domain, and when the SRI domain corresponding to the SRS resource set does not exist in the DCI, the terminal equipment determines the target power control parameter based on the agreed rule.

In the embodiment of the present application, when the number of SRS resources included in the SRS resource set is greater than 1, an SRI domain corresponding to the SRS resource set exists in the DCI, and at this time, the terminal device determines a target power control parameter based on the SRI domain.

In an alternative implementation manner, when the SRI domain corresponding to the SRS resource set exists in the DCI, the terminal device may also determine the target power control parameter based on the agreed rule.

2. The number of SRS resources in the SRS resource set configured by the network equipment comprises:

(2.1) the number of SRS resources in the first SRS resource set is 1 and the number of SRS resources in the second SRS resource set is 1;

(2.2) the number of SRS resources in the first SRS resource set is 1 and the number of SRS resources in the second SRS resource set is at least two;

(2.3) the number of SRS resources in the first SRS resource set is at least two and the number of SRS resources in the second SRS resource set is at least two.

In the case of (2.3), when the number of SRS resources in the SRS resource set is greater than 1 due to the related art, there is an SRI field corresponding to the SRS resource set in the DCI. Therefore, in the case of (2.3), the DCI may include a first SRI field corresponding to the first SRS resource set and a second SRI field corresponding to the second SRS resource set, and at this time, the terminal device determines target power control parameters corresponding to the two SRS resource sets based on the two SRI fields, respectively.

In an optional implementation manner, when the DCI includes a first SRI field corresponding to the first SRS resource set and a second SRI field corresponding to the second SRS resource set, the terminal device may also determine target power control parameters corresponding to the two SRS sets based on a rule.

The present embodiment only exemplifies the cases of (2.1) and (2.2), but does not specify the case of (2.3).

3. The SRS resource set for PUSCH indicated by DCI, and the number of transmissions of PUSCH are different from each other including:

(3.1) performing a single transmission of PUSCH using the first SRS resource on the first SRS resource set;

(3.2) performing PUSCH retransmission using the first SRS resource on the first SRS resource set;

(3.3) performing PUSCH retransmission using the first SRS resource on the first SRS resource set and the second SRS resource on the second SRS resource set.

Based on the description of the situation of the SRS resource quantity in the SRS resource set configured for the network device in the 2 nd item, the following description is given:

the first SRS resource set contains only one SRS resource, i.e., the first SRS resource.

The second SRS resource set may include only one SRS resource, i.e., the second SRS resource; the second set of SRS resources may also include at least two SRS resources.

The following description is made, by way of example, for both cases (3.1) and (3.2):

the first SRS resource set indicates an SRS resource set with 1 SRS resource number in a plurality of SRS resource sets configured by the network device. For example, when the network device configures two SRS resource sets with SRS resource number 1: the first SRS resource set in both cases (3.1) and (3.2) may be either SRS resource set 1 or SRS resource set 2.

Based on the permutation and combination of the above several cases, the following ten exemplary embodiments are given:

the DCI indicates a single transmission of PUSCH through a first SRS resource in a first SRS resource set; and determining a target power control parameter according to a first SRI domain corresponding to the first SRS resource set in the DCI.

(II) DCI indicates that the repeated transmission of the PUSCH is carried out through the first SRS resource in the first SRS resource set; and determining a target power control parameter according to a first SRI domain corresponding to the first SRS resource set in the DCI.

(III) DCI indicates that the repeated transmission of the PUSCH is performed through the first SRS resource in the first SRS resource set and the second SRS resource in the second SRS resource set; and determining a target power control parameter according to a first SRI domain corresponding to the first SRS resource set in the DCI, and determining the target power control parameter according to a second SRI domain corresponding to the second SRS resource set in the DCI.

The SRI field may or may not include a second SRI field corresponding to the second SRS resource set. The second SRI field is for indicating a target power control parameter in a second power control parameter set.

For example, the DCI is used to indicate PUSCH is a transmission based on a first SRS resource in a first SRS resource set.

In step 2221, the terminal device receives DCI sent by the network device, where the DCI is used to schedule PUSCH and the DCI includes an SRI field.

In step 251, the receiving terminal device performs PUSCH transmission through the first SRS resource according to the first set of power control parameters.

For example, the network device configures two SRS resources set (corresponding to SRS resource set0 and SRS resource set 1), where only one SRS resource is contained in each of SRS resource set0 and SRS resource set 1. When the network equipment is scheduled by the DCI, the DCI comprises 2 SRI domains, and each SRI domain corresponds to one SRS resource set configured by the network equipment. The network device sets a value (e.g., 1) in the SRI field, where the value is used to indicate the identification of the power control parameter (corresponding to the RRC configured SRI-PUSCH-powercontrol id) of the PUSCH during SRS resource transmission through the SRS resource set corresponding to the SRI field. And the terminal equipment receives the PDCCH for scheduling the PUSCH, and determines the scheduled PUSCH as a resource based on a certain SRS resource set to transmit according to the PDCCH. The terminal equipment obtains the value in the SRI domain indicated by the DCI, and determines a unique group of power control parameters (SRI-PUSCH-PowerControl) from a plurality of groups of power control parameters (list of SRI-PUSCH-PowerControl) corresponding to the resource set according to the value of the SRI domain corresponding to the resource set. And when the terminal equipment performs PUSCH transmission through SRS resources in the SRS resource set, setting the power of the PUSCH according to the power control parameter and performing single TRP transmission.

If the SRS resource set indicated by the DCI and used for PUSCH transmission only includes at least 2 SRS resources, the terminal device determines a target power control parameter during PUSCH transmission based on a value of the SRI domain indicated by the DCI and at least one group of power control parameters corresponding to the SRS resource set. And the terminal equipment performs PUSCH transmission according to SRS resources, power control parameters and the like indicated by the network equipment.

Referring to fig. 4, a flowchart of a method for determining a power control parameter according to an embodiment of the present application is shown, and the method may be applied to the system architecture shown in fig. 1. The method comprises the following steps.

Illustratively, the at least two SRS resource sets include a first SRS resource set having a number of SRS resources of 1 and a second SRS resource set having a number of SRS resources of 1 or more.

The SRI domain includes a first SRI domain corresponding to the first SRS resource set.

For example, the DCI is used to indicate PUSCH as a repeated transmission based on the first SRS resource in the first SRS resource set.

In step 2231, the terminal device determines, based on the DCI, that the scheduled PUSCH is a repeated transmission based on the first SRS resource in the first SRS resource set.

In step 243, the terminal device performs PUSCH retransmission through the first SRS resource according to the first set of power control parameters.

For example, the repeated transmission refers to at least two PUSCH transmissions by the terminal device through the first SRS resource.

In step 253, the network device receives repeated PUSCH transmission by the terminal device through the first SRS resource according to the first set of power control parameters.

In summary, in the method provided in this embodiment, by configuring the first SRI field corresponding to the first SRS resource set in the DCI, determining the first set of power control parameters corresponding to the first SRS resource set according to the first SRI field, and using the first SRS resource of the first SRS resource set according to the first set of power control parameters according to the indication of the DCI, performing PUSCH retransmission.

Referring to fig. 5, a flowchart of a method for determining a power control parameter according to an embodiment of the present application is shown, and the method may be applied to the system architecture shown in fig. 1. The method comprises the following steps.

Illustratively, the at least two SRS resource sets include a first SRS resource set and a second SRS resource set. The number of SRS resources in the first set of SRS resources is 1 and the number of SRS resources in the second set of SRS resources is 1 or more.

The network device configures two SRS resource sets for uplink transmission of the terminal device. At least one of the resource sets contains only 1 SRS resource.

The terminal device receives 2 SRS resource sets configured by the network device, wherein at least one of the resource sets contains only 1 SRS resource.

The SRI domain includes a first SRI domain corresponding to the first SRS resource set and a second SRI domain corresponding to the second SRS resource set.

For example, the DCI is used to indicate PUSCH as a repeated transmission based on a first SRS resource in a first SRS resource set and a second SRS resource in a second SRS resource set.

For example, the network device performs PUSCH scheduling through DCI, where the PUSCH scheduling is scheduling for repeated transmission based on SRS resources in the two SRS resource sets. Two SRI domains exist in the DCI, which are respectively used for indicating uplink power control parameters of PUSCH transmission when scheduling is performed based on SRS resources in corresponding resource sets. The SRI field corresponding to the SR resource set, which only contains 1 SRS resource, occupies at least 1bit.

For example, the terminal device receives DCI of a scheduled PUSCH, where the scheduled PUSCH is repeated for one or more SRS resources in 2 SRS resource sets configured based on the network device.

In step 2232, the terminal device determines, based on the DCI, that the scheduled PUSCH is a repeated transmission based on the first SRS resource in the first SRS resource set and the second SRS resource in the second SRS resource set.

The target power control parameters include a first group of power control parameters corresponding to the first SRS resource set and a second group of power control parameters corresponding to the second SRS resource set.

Illustratively, the second set of power control parameters is a target power control parameter corresponding to the second SRS resource set.

For example, the terminal device determines, through two SRI fields in the same DCI, a power control parameter of the terminal when uplink repeated transmission is performed based on SRS resources in the two SRS resource sets. The terminal acquires index of the SRI domain and a group of uplink power control sets corresponding to SRS resource sets corresponding to the SRI domain to determine parameters related to power control, wherein the parameters comprise reference symbols of P0, alpha and path loss and index values of closed loop power control parameters.

In step 242, the terminal device performs PUSCH retransmission through the first SRS resource according to the first set of power control parameters and through the second SRS resource according to the second set of power control parameters.

The target SRS resources include a first SRS resource in the first SRS resource set and a second SRS resource in the second SRS resource set.

For example, the terminal device sets power values when PUSCH transmission is performed through SRS resources in the corresponding SRS resource set according to uplink power control parameters indicated by the network device, and performs PUSCH transmission.

In step 252, the network device receives repeated PUSCH transmission by the terminal device through the first SRS resource according to the first set of power control parameters and through the second SRS resource according to the second set of power control parameters.

Illustratively, the network device performs PUSCH detection based on the scheduled resources.

For example, the network device configures two SRS resource sets (corresponding to SRS resource set0 and SRS resource set 1), where only one SRS resource is contained in each of SRS resource set0 and SRS resource set 1. When the network equipment is scheduled by the DCI, the DCI comprises 2 SRI domains, and each SRI domain corresponds to one SRS resource set configured by the network equipment. The network device sets a value (e.g., 1) in the SRI field, where the value is used to indicate the identification of the power control parameter (corresponding to the RRC configured SRI-PUSCH-powercontrol id) of the PUSCH during SRS resource transmission through the SRS resource set corresponding to the SRI field. And the terminal equipment receives the PDCCH for scheduling the PUSCH, and determines the scheduled PUSCH as the resource based on the two SRS resource sets to carry out repeated transmission according to the PDCCH. The terminal equipment obtains the value in the SRI domain indicated by the DCI, and determines a unique group of power control parameters (SRI-PUSCH-PowerControl) according to the value of the SRI domain corresponding to the resource set and a plurality of groups of power control parameters (list of SRI-PUSCH-PowerControl) corresponding to the resource set. The terminal equipment sets the power of the PUSCH according to the power control parameter when the PUSCH is transmitted through the SRS resources in the SRS resource set, and determines a unique group of power control parameters according to the value of the SRI domain corresponding to the resource set and a plurality of groups of power control parameters corresponding to the resource set when the PUSCH is transmitted through the SRS resources in another SRS resource set.

There is no SRI field in the DCI. The network equipment sets the power of the PUSCH according to a first group of power control parameters in at least one group of power control parameters respectively corresponding to the two SRS resource sets by specifying the SRI-free domain in advance.

For example, the terminal receives DCI of a scheduled PUSCH, and the scheduled PUSCH is repeatedly transmitted for SRS resources in 2 SRS resource sets configured based on the network device.

Step 235, the terminal device determines an x-th group of power control parameters in a first power control parameter set corresponding to the first SRS resource set as a first group of power control parameters according to a first stipulation rule, wherein x is a positive integer; and determining a y-th group of power control parameters in a second power control parameter set corresponding to the second SRS resource set as a second group of power control parameters according to a third stipulated rule, wherein y is a positive integer.

When the network equipment schedules through the DCI, the DCI comprises no SRI domain.
