Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a PUSCH transmission method, apparatus and storage medium. Background Technology

[0002] In wireless communication systems, Physical Uplink Shared Channel (PUSCH) transmission can be scheduled using Downlink Control Information (DCI) or authorized based on semi-static signaling configuration. In the 3rd Generation Partnership Project (3GPP) New Radio (NR) system, DCI formats 0_0, 0_1, and 0_2 can all be used to schedule PUSCH transmission.

[0003] In a Multiple-Transmission and Reception Point (M-TRP) scenario, when the PUSCH is transmitted in M-TRP and the PUSCH scheduled by the DCI format corresponding to the PUSCH is configured for Single-Transmission and Reception Point (S-TRP) transmission, the network device can only configure one Sounding Reference Signal (SRS) resource set for the PUSCH scheduled by the DCI format, thus preventing the PUSCH from being transmitted in M-TRP.

[0158] Figure 6 This is the second schematic diagram of the structure of the PUSCH transmission device provided in the embodiments of this application. Detailed Implementation

[0159] To better describe the technical solutions in the embodiments of this application, relevant knowledge is introduced below.

[0160] (1) PUSCH transmission

[0161] In wireless communication systems, PUSCH transmission can be scheduled via DCI or configured with grant based on semi-static signaling. Configuration grant based on semi-static signaling is also known as configuration grant, no-scheduling, no-grant, no-scheduling grant, and non-dynamic grant. Correspondingly, PUSCH based on semi-static signaling configuration grant is also called configured grant (CG) PUSCH, grant-less / grant-free PUSCH, no-scheduling PUSCH, no-scheduling grant PUSCH, and uplink transmission without dynamic grant.

[0162] (2) PUSCH transmission scheme

[0163] In the 3GPP NR system, DCI format 0_0, DCI format 0_1, and DCI format 0_2 can all be used to schedule PUSCH transmissions. For ease of description, PUSCHs with configured licensing are referred to as CG PUSCHs below. CG PUSCHs include two licensing schemes: Type 1 and Type 2. The actual uplink licensing for Type 1 is provided through Radio Resource Control (RRC) signaling, while the actual uplink licensing for Type 2 is provided through the Physical Downlink Control Channel (PDCCH).

[0164] (3) PUSCH transmission mode

[0165] PUSCH supports two transmission schemes: codebook-based transmission and non-codebook-based transmission. When the parameter txConfig in the PUSCH configuration control element (PUSCH-Config Information Element, PUSCH-Config IE) is configured as "codebook", PUSCH transmission is configured as codebook-based; when the parameter txConfig in the PUSCH-Config IE is set to "nonCodebook", PUSCH transmission is configured as non-codebook-based. If the higher-level parameter txConfig is not configured, PUSCH transmission is not expected to be scheduled via DCI format 0_1.

[0166] (4) PUSCH transmission parameters

[0167] Network devices can configure the precodingAndNumberOfLayers field for CG Type 1 PUSCH via RRC signaling to indicate the corresponding precoding and / or layer number for CG Type 1 PUSCH transmission; and configure the srs-ResourceIndicator field to indicate the corresponding SRS resource for CG Type 1 PUSCH transmission.

[0168] (5) PUSCH time domain allocation table

[0169] The Time Domain Allocation List (TDRA) for PUSCH is given in 3GPP TS 38.214. When the field `pusch-TimeDomainAllocationListDCI-0-1` is not configured, the `pusch-TimeDomainAllocationList` field applies to DCI format 0_0 and DCI format 0_1. The fields `pusch-TimeDomainAllocationListDCI-0-2-r16`, `pusch-TimeDomainAllocationListDCI-0-1-r16`, or `pusch-TimeDomainAllocationListForMultiPUSCH-r16` will not be configured simultaneously with the `pusch-TimeDomainAllocationList` field by the network.

[0170] (6) PUSCH transmission parameter determination process

[0171] Network devices configure corresponding SRS resource sets for PUSCHs scheduled for DCI format 0_1 ​​and DCI format 0_2 respectively via RRC signaling. CG Type 1 PUSCHs use the SRS resource set corresponding to the PUSCHs scheduled for DCI format 0_1 ​​configured by the network device. After determining the SRS resource set corresponding to a CG Type 1 PUSCH, the network device can instruct the actual transmission of the corresponding SRS resources within that SRS resource set. This further enables the terminal (User Equipment, UE) to determine the precoding and / or layer number of the CG Type 1 PUSCH transmission based on the SRS resources actually transmitted by the CG Type 1 PUSCH.

[0172] In M-TRP scenarios, when a CG Type 1 PUSCH is transmitted via M-TRP, and a PUSCH scheduled by DCI format 0_1 ​​is configured for S-TRP transmission, the network device only configures one SRS resource set for the DCI format 0_1 ​​scheduled PUSCH. Using this as the SRS resource set for the CG Type 1 PUSCH will prevent the CG Type 1 PUSCH from being transmitted via M-TRP. Existing technologies cannot determine the SRS resource set, precoding and / or layer number, and SRS resources for CG Type 1 PUSCH transmission in M-TRP scenarios.

[0173] To address the aforementioned problems in the existing technology, embodiments of this application provide a PUSCH transmission method, apparatus, and storage medium. The terminal device determines one or more SRS resource sets corresponding to the PUSCH by configuring a first SRS resource set with a first parameter and / or configuring a second SRS resource set with a second parameter, so that when the PUSCH scheduled by DCI format0_1 can only be S-TRP transmission, the PUSCH can also be M-TRP transmission.

[0174] In the embodiments of this application, the term "and / or" describes the relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. The character " / " generally indicates that the preceding and following associated objects have an "or" relationship.

[0175] In the embodiments of this application, "first" and "second" are used to distinguish similar objects, rather than to describe a specific order or sequence.

[0176] In this application, "determining B based on A" means that factor A must be considered when determining B. It is not limited to "B can be determined based solely on A," but should also include: "determining B based on A and C," "determining B based on A, C, and E," "determining C based on A, and further determining B based on C," etc. Additionally, it can include using A as a condition for determining B, for example, "when A satisfies the first condition, B is determined using the first method"; another example, "when A satisfies the second condition, B is determined," etc.; another example, "when A satisfies the third condition, B is determined based on the first parameter," etc. Of course, it can also be a condition where A is a factor in determining B, for example, "when A satisfies the first condition, C is determined using the first method, and B is further determined based on C," etc.

[0177] In the embodiments of this application, the term "multiple" refers to two or more, and other quantifiers are similar.

[0178] The technical solutions provided in this application can be applied to various systems, especially 5G systems. For example, applicable systems include Global System for Mobile Communication (GSM), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA) General Packet Radio Service (GPRS), Long Term Evolution (LTE), LTE Frequency Division Duplex (FDD), LTE Time Division Duplex (TDD), Long Term Evolution Advanced (LTE-A), Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX), and 5G New Radio (NR). All of these systems include terminal equipment and network equipment. The system may also include a core network component, such as the Evolved Packet System (EPS) or the 5G system (5GS).

[0179] The terminal devices involved in the embodiments of this application can be devices that provide voice and / or data connectivity to users, handheld devices with wireless connectivity, or other processing devices connected to a wireless modem. The names of the terminal devices may differ in different systems; for example, in a 5G system, a terminal device can be called User Equipment (UE). Wireless terminal devices can communicate with one or more core networks (CNs) via a Radio Access Network (RAN). Wireless terminal devices can be mobile terminal devices, such as mobile phones (or "cellular" phones) and computers with mobile terminal devices, for example, portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile devices that exchange voice and / or data with the RAN. Examples include Personal Communication Service (PCS) phones, cordless phones, Session Initiated Protocol (SIP) phones, Wireless Local Loop (WLL) stations, and Personal Digital Assistants (PDAs). Wireless terminal equipment can also be referred to as a system, subscriber unit, subscriber station, mobile station, mobile station, remote station, access point, remote terminal, access terminal, user terminal, user agent, or user device, but this application embodiment does not limit the terminology.

[0180] The network device involved in this application embodiment can be a base station, which may include multiple cells providing services to terminals. Depending on the specific application, a base station may also be called an access point, or a device in an access network that communicates with a wireless terminal device through one or more sectors on the air interface, or other names. The network device can be used to exchange received air frames with Internet Protocol (IP) packets, acting as a router between the wireless terminal device and the rest of the access network, where the rest of the access network may include an Internet Protocol (IP) communication network. The network device can also coordinate the attribute management of the air interface. For example, the network equipment involved in the embodiments of this application can be a base transceiver station (BTS) in a Global System for Mobile Communications (GSM) or Code Division Multiple Access (CDMA) system, a NodeB in a Wide-band Code Division Multiple Access (WCDMA) system, an evolved Node B (eNB or e-NodeB) in a Long Term Evolution (LTE) system, a 5G base station (gNB) in a Next Generation System, a Home evolved Node B (HeNB), a relay node, a Femto, a Pico, etc., and is not limited in the embodiments of this application. In some network structures, the network equipment may include centralized unit (CU) nodes and distributed unit (DU) nodes, and the centralized unit and distributed unit may also be geographically separated.

[0181] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0182] Figure 1 This is one of the flowcharts illustrating the PUSCH transmission method provided in the embodiments of this application, such as... Figure 1As shown, this application provides a PUSCH transmission method, the execution subject of which can be a terminal (User Equipment, UE), and the method includes at least the following steps:

[0183] Step 101: Determine the target SRS resource set based on the first SRS resource set configured by the first parameter and / or the second SRS resource set configured by the second parameter. The target SRS resource set is one or more SRS resource sets corresponding to PUSCH.

[0184] Specifically, the terminal determines the target SRS resource set based on the first SRS resource set configured by the first parameter and / or the second SRS resource set configured by the second parameter. The first parameter can be the higher-level parameter srs-ResourceSetToAddModList, and the second parameter can be the higher-level parameter srs-ResourceSetToAddModListDCI-0-2.

[0185] The network device configures the SRS resource set for the PUSCH scheduled by DCI format 0_1, which is the first SRS resource set included in the first parameter srs-ResourceSetToAddModList. The network device configures the SRS resource set for the PUSCH scheduled by DCI format 0_2, which is the second SRS resource set included in the second parameter srs-ResourceSetToAddModListDCI-0-2.

[0186] When the PUSCH is transmitted or received in S-TRP mode, the target SRS resource set is one SRS resource set corresponding to that PUSCH. When the PUSCH is transmitted or received in M-TRP mode, the target SRS resource set is multiple SRS resource sets corresponding to that PUSCH.

[0187] Optionally, the terminal determines the time-domain resources corresponding to the PUSCH transmission based on the number of sets in the first SRS resource set and / or the second SRS resource set.

[0188] The PUSCH transmission method provided in this application embodiment allows the terminal to determine one or more SRS resource sets corresponding to the PUSCH by configuring a first SRS resource set with a first parameter and / or configuring a second SRS resource set with a second parameter, so that when the PUSCH scheduled by DCI format0_1 can only be S-TRP transmission, the PUSCH can also be M-TRP transmission.

[0189] Optionally, the terminal also receives SRS resource indication information sent by the network, which indicates SRS resources from the target SRS resource set. Based on the SRS resource indication information, the UE can determine the SRS resource corresponding to the PUSCH, and thus further determine the precoding and / or transport layer number corresponding to the PUSCH.

[0190] Optionally, PUSCH satisfies the first condition, which includes:

[0191] PUSCH is configured with target information that indicates at least one of the following:

[0192] PUSCH transmit or receive modes;

[0193] PUSCH is associated with multiple TRPs;

[0194] PUSCH is associated with multiple precoding and / or layers;

[0195] The second precoding and / or layer number associated with PUSCH;

[0196] PUSCH is associated with multiple SRS resources;

[0197] The second set of SRS resources associated with PUSCH;

[0198] PUSCH is associated with multiple sets of power control parameters;

[0199] The second set of power control parameters associated with PUSCH;

[0200] PUSCH is associated with multiple spatially related parameters;

[0201] The second set of spatially related parameters associated with PUSCH;

[0202] PUSCH is associated with multiple TCI states;

[0203] The second set of TCI states associated with PUSCH.

[0204] Optionally, the power control parameters include at least one of the following:

[0205] Parameters used to indicate the road loss reference signal;

[0206] Power control parameter p0;

[0207] Alternatively, path loss compensation factor alpha.

[0208] Specifically, the terminal can determine one or more SRS resource sets corresponding to a PUSCH based on whether the network device has configured target information for the PUSCH.

[0209] When the network device has configured target information for PUSCH, the terminal uses the first method to determine the target SRS resource set; when the network device has not configured target information for PUSCH, the terminal uses the other method to determine the target SRS resource set.

[0210] The target information is used to indicate at least one of the following:

[0211] The sending or receiving mode of PUSCH, for example, the network device is configured to send PUSCH as S-TRP or M-TRP transmission;

[0212] PUSCH is associated with multiple Transmission Reception Points (TRPs);

[0213] PUSCH is associated with multiple precoding and / or layer numbers. For example, a network device may configure two pieces of information for PUSCH to indicate the number of precoding and / or transmission layers (e.g., precodingAndNumberOfLayers and precodingAndNumberOfLayers2 are configured at the same time; or precoding and precoding2 are configured at the same time).

[0214] The second precoding and / or layer number associated with PUSCH, for example, the network device configures precodingAndNumberOfLayers2 for PUSCH;

[0215] PUSCH is associated with multiple SRS resources. For example, a network device may configure two pieces of information for PUSCH to indicate SRS resources (e.g., srsResourceIndicator and srsResourceIndicator2 are configured at the same time).

[0216] The second set of SRS resources associated with PUSCH, such as ResourceIndicator2 configured for PUSCH by the network device;

[0217] PUSCH is associated with multiple sets of power control parameters. For example, network devices may configure two sets of information for PUSCH to indicate power control parameters (e.g., pathlossReferenceIndex and pathlossReferenceIndex2 are configured at the same time; or p0-PUSCH-Alpha and p0-PUSCH-Alpha2 are configured at the same time).

[0218] The second set of power control parameters associated with PUSCH, such as pathlossReferenceIndex2 and / or p0-PUSCH-Alpha2 configured for PUSCH by the network device;

[0219] PUSCH is associated with multiple spatially related parameters, which are used to indicate the spatial filtering of PUSCH. For example, network devices configure SpatialRelationInfo and / or SpatialRelationInfo2 for PUSCH.

[0220] The second set of spatially related parameters associated with PUSCH, such as SpatialRelationInfo2 configured by the network device for PUSCH;

[0221] PUSCH is associated with multiple Transmission Configuration Indication (TCI) states, which are used to indicate the quasi-colocation (QCL) relationship of PUSCH.

[0222] The second set of TCI states associated with PUSCH.

[0223] The power control parameters include at least one of the following: a parameter used to indicate the path loss reference signal; a power control parameter p0; or a path loss compensation factor alpha.

[0224] Optionally, the target SRS resource set is determined based on the first SRS resource set configured with the first parameter and / or the second SRS resource set configured with the second parameter, including at least one of the following:

[0225] When the number of sets in the first SRS resource set is N, the target SRS resource set is determined based on the first SRS resource set;

[0226] When the number of sets in the first SRS resource set is 1 and the number of sets in the second SRS resource set is N, the target SRS resource set is determined based on the second SRS resource set.

[0227] When the number of sets in the first SRS resource set is 1 and the number of sets in the second SRS resource set is 1, the target SRS resource set is determined based on the first SRS resource set.

[0228] When the number of sets in the first SRS resource set is 1 and the number of sets in the second SRS resource set is 1, it is not expected that the network device will be configured with target information.

[0229] Where N is an integer greater than or equal to 2.

[0230] Specifically, when the terminal determines that the network device has configured target information for PUSCH, the terminal device determines the target SRS resource set based on the number of sets in the first SRS resource set and / or the number of sets in the second SRS resource set.

[0231] Taking PUSCH as an example, with CG Type 1 PUSCH, the first parameter being srs-ResourceSetToAddModList, and the second parameter being srs-ResourceSetToAddModListDCI-0-2, we will explain further.

[0232] If the CG Type 1 PUSCH is configured for S-TRP transmission (or only one precoding and / or layer number is configured, or no second precoding and / or layer number is configured, or only one SRS resource is configured, or no second set of SRS resources is configured, or only one set of power control parameters is configured, or no second set of power control parameters is configured, or only one space-related information parameter is configured, or no second set of space-related information parameters is configured, or only one Transmission Configuration Indicator (TCI) state is configured, or no second set of TCI states is configured), then the target SRS resource set is determined based on the first SRS resource set configured with the first parameter and / or the second SRS resource set configured with the second parameter, including at least one of the following:

[0233] ① If the number of sets in the first SRS resource set is N, and N is greater than or equal to 2, it means that srs-ResourceSetToAddModList includes multiple SRS resource sets. The terminal device determines the target SRS resource set based on the first SRS resource set. For example, the target SRS resource set is the SRS resource set with the smallest identifier (Identity, ID) in the first SRS resource set. Another example is that the target SRS resource set is the SRS resource set with the largest ID in the first SRS resource set.

[0234] ② If the number of sets in the first SRS resource set is 1 and the number of sets in the second SRS resource set is N, where N is greater than or equal to 2, it means that the first SRS resource set can be used for S-TRP transmission of CG Type 1 PUSCH, and the second SRS resource set can also be used for S-TRP transmission of CG Type 1 PUSCH.

[0235] ③ If the number of sets in the first SRS resource set is 1 and the number of sets in the second SRS resource set is 1, the first SRS resource set can be used for S-TRP transmission of CG Type 1 PUSCH.

[0236] If the CG Type 1 PUSCH is configured for M-TRP transmission (or configured with 2 precoding and / or layers, or configured with a second precoding and / or layers, or configured with 2 SRS resources, or configured with a second set of SRS resources, or configured with 2 sets of power control parameters, or configured with a second set of power control parameters, or configured with 2 spatially related parameters, or configured with a second set of spatially related parameters, or configured with 2 Transmission Configuration Indicator (TCI) states, or configured with a second set of TCI states), then the target SRS resource set is determined based on the first SRS resource set configured with the first parameter and / or the second SRS resource set configured with the second parameter, including at least one of the following:

[0237] ① If the number of sets in the first SRS resource set is N, and N is greater than or equal to 2, it means that srs-ResourceSetToAddModList includes multiple SRS resource sets, and the terminal determines the target SRS resource set based on the first SRS resource set. For example, the target SRS resource set is multiple SRS resource sets in the first SRS resource set.

[0238] ② If the number of elements in the first SRS resource set is 1, and the number of elements in the second SRS resource set is N, where N is greater than or equal to 2, then the first SRS resource set cannot be used for M-TRP transmission of CG Type 1 PUSCH. If CG Type 1 PUSCH is configured for M-TRP transmission, multiple SRS resource sets in the second SRS resource set configured by the second parameter can be used as the target SRS resource set.

[0239] ③ If the number of elements in both the first and second SRS resource sets is 1, it indicates that the current configuration does not support M-TRP transmission of CG Type 1 PUSCH. S-TRP transmission of CG Type 1 PUSCH can be performed using the first SRS resource set. In this case, the terminal may consider this configuration incorrect, or the terminal may not expect the network device to configure the target information.

[0240] The PUSCH transmission method provided in this application embodiment allows the terminal to determine one or more SRS resource sets corresponding to the PUSCH by configuring target information for the PUSCH in the network device, through the first SRS resource set configured by the first parameter and / or the second SRS resource set configured by the second parameter, so that the PUSCH scheduled by DCI format0_1 can only be transmitted for S-TRP, and the PUSCH can also be transmitted for M-TRP.

[0241] Optionally, the target SRS resource set is determined based on the first SRS resource set configured with the first parameter and / or the second SRS resource set configured with the second parameter, including at least one of the following:

[0242] When the number of sets in the first SRS resource set is M, the target SRS resource set is determined to be one or M SRS resource sets in the first SRS resource set.

[0243] When the number of sets in the first SRS resource set is 1 and the number of sets in the second SRS resource set is M, the target SRS resource set is determined to be either M SRS resource sets in the second SRS resource set or 1 SRS resource set in the first SRS resource set.

[0244] If the number of sets in the first SRS resource set is 1 and the number of sets in the second SRS resource set is 1, then the target SRS resource set is determined to be one SRS resource set in the first SRS resource set.

[0245] When the number of sets in the first SRS resource set is 1 and the number of sets in the second SRS resource set is 1, it is not expected that the network device will be configured with target information.

[0246] Where M is an integer greater than or equal to 2.

[0247] Specifically, when the terminal determines that the network device has configured target information for PUSCH, the terminal determines the target SRS resource set based on the number of sets in the first SRS resource set and / or the number of sets in the second SRS resource set.

[0248] Taking PUSCH as an example, with CG Type 1 PUSCH, the first parameter being srs-ResourceSetToAddModList, and the second parameter being srs-ResourceSetToAddModListDCI-0-2, we will explain further.

[0249] If the CG Type 1 PUSCH is configured for S-TRP transmission or is not configured with target information (e.g., only one precoding and / or layer number is configured, or no second precoding and / or layer number is configured, or only one SRS resource is configured, or no second set of SRS resources is configured, or only one set of power control parameters is configured, or no second set of power control parameters is configured, or only one space-related information parameter is configured, or no second set of space-related information parameters is configured, or only one Transmission Configuration Indicator (TCI) status is configured, or no second set of TCI status is configured), then the target SRS resource set is determined based on the first SRS resource set configured with the first parameter and / or the second SRS resource set configured with the second parameter, including at least one of the following:

[0250] ① If the number of sets in the first SRS resource set is M, and M is greater than or equal to 2, it means that srs-ResourceSetToAddModList includes multiple SRS resource sets, and the terminal determines that the target SRS resource set is one of the SRS resource sets in the first SRS resource set.

[0251] In the case of multiple SRS resource sets within the first SRS resource set, each SRS resource set has an SRS resource set ID, and all SRS resources within an SRS resource set are associated with the same TRP. Therefore, the target SRS resource set can be determined by the ID of the SRS resource set in the first SRS resource set that meets preset conditions. For example, the target SRS resource set is the SRS resource set with the smallest ID in the first SRS resource set. Another example is that the target SRS resource set is the SRS resource set with the largest ID in the first SRS resource set.

[0252] ② If the number of sets in the first SRS resource set is 1 and the number of sets in the second SRS resource set is M, where M is greater than or equal to 2, it means that one SRS resource set in the first SRS resource set can be used for S-TRP transmission of CG Type 1 PUSCH, and one SRS resource set in the second SRS resource set can also be used for S-TRP transmission of CG Type 1 PUSCH.

[0253] ③ If the number of sets in the first SRS resource set is 1 and the number of sets in the second SRS resource set is 1, an SRS resource set in the first SRS resource set can be used for S-TRP transmission of CG Type 1 PUSCH, and the target SRS resource set is an SRS resource set in the first SRS resource set.

[0254] If the CG Type 1 PUSCH is configured for M-TRP transmission or is configured with target information (e.g., configured for M-TRP transmission, or configured with two precoding and / or layer numbers, or configured with a second precoding and / or layer number, or configured with two SRS resources, or configured with a second set of SRS resources, or configured with two sets of power control parameters, or configured with a second set of power control parameters, or configured with two spatially related parameters, or configured with a second set of spatially related parameters, or configured with two Transmission Configuration Indicator (TCI) states, or configured with a second set of TCI states), then the target SRS resource set is determined based on the first SRS resource set configured with the first parameter and / or the second SRS resource set configured with the second parameter, including at least one of the following:

[0255] ① If the number of sets in the first SRS resource set is M, and M is greater than or equal to 2, it means that srs-ResourceSetToAddModList includes multiple SRS resource sets, and the terminal can determine that the target SRS resource set is the M SRS resource sets in the first SRS resource set.

[0256] ② If the number of sets in the first SRS resource set is 1, and the number of sets in the second SRS resource set is M, where M is greater than or equal to 2, it means that the first SRS resource set cannot be used for M-TRP transmission of CG Type 1 PUSCH. The terminal can determine that the target SRS resource set is M SRS resource sets in the second SRS resource set.

[0257] ③ If the number of elements in both the first and second SRS resource sets is 1, it indicates that the current configuration does not support M-TRP transmission of CG Type 1 PUSCH. S-TRP transmission of CG Type 1 PUSCH can be performed using the first SRS resource set. In this case, the terminal can consider this configuration incorrect, and the terminal device does not expect the network device to configure the target information.

[0258] Optionally, if the number of sets in the first SRS resource set and the number of sets in the second SRS resource set are both 1, the network device should not configure target information for PUSCH, such as pathlossReferenceIndex2, ResourceIndicator2, p0-PUSCH-Alpha2, or precodingAndNumberOfLayers2.

[0259] The PUSCH transmission method provided in this application embodiment allows the terminal to determine one or more SRS resource sets corresponding to the PUSCH by configuring target information for the PUSCH in the network device, through the first SRS resource set configured by the first parameter and / or the second SRS resource set configured by the second parameter, so that when the PUSCH scheduled by DCI format0_1 can only be transmitted for S-TRP, the PUSCH can also be transmitted for M-TRP.

[0260] Optionally, if no target information is configured for PUSCH, the target SRS resource set is determined based on the first SRS resource set configured with the first parameter and / or the second SRS resource set configured with the second parameter, including:

[0261] The target SRS resource set is determined based on the first SRS resource set.

[0262] Specifically, when the terminal determines that the network device has not configured target information for PUSCH, the terminal determines the target SRS resource set based on the first SRS resource set. The target SRS resource set can be one or more SRS resource sets in the first SRS resource set.

[0263] Optionally, if the PUSCH is configured for S-TRP transmission or no target information is configured, even if both the first and second parameters configure SRS resource sets, one SRS resource set from the first SRS resource set can be used for S-TRP transmission of the PUSCH. If the PUSCH is configured for M-TRP transmission, the terminal can use multiple SRS resource sets from the first SRS resource set for M-TRP transmission of the PUSCH.

[0264] Optionally, the method further includes:

[0265] Determine the number of third parameters corresponding to PUSCH, where the third parameters indicate at least one of the following:

[0266] PUSCH transmit or receive modes;

[0267] PUSCH associated TRP;

[0268] PUSCH associated precoding and / or layer number;

[0269] SRS resources associated with PUSCH;

[0270] PUSCH-related power control parameters;

[0271] Spatial information associated with PUSCH;

[0272] The TCI state associated with PUSCH.

[0273] Optionally, the power control parameters include at least one of the following:

[0274] Parameters used to indicate the road loss reference signal;

[0275] Power control parameter p0;

[0276] Alternatively, path loss compensation factor alpha.

[0277] Specifically, before determining the target SRS resource set based on the first SRS resource set configured with the first parameter and / or the second SRS resource set configured with the second parameter, the terminal may also determine the number of the third parameters corresponding to the PUSCH.

[0278] The third parameter is used to indicate at least one of the following:

[0279] The sending or receiving mode of PUSCH, for example, the network device is configured to send PUSCH as S-TRP or M-TRP transmission;

[0280] The TRP associated with PUSCH is as follows: when PUSCH is transmitted as an S-TRP, PUSCH is associated with one TRP; when PUSCH is transmitted as an M-TRP, PUSCH is associated with multiple TRPs.

[0281] The precoding and / or layer number associated with PUSCH, for example, the network device is configured with two pieces of information indicating the precoding and / or transmission layer number for PUSCH (e.g., precodingAndNumberOfLayers and precodingAndNumberOfLayers2 are configured at the same time; or, for example, precoding and precoding2 are configured at the same time).

[0282] The SRS resource associated with PUSCH, for example, the network device configures two pieces of information for PUSCH to indicate the SRS resource (e.g., ResourceIndicator and ResourceIndicator2 are configured at the same time);

[0283] PUSCH associated power control parameters, such as network devices configuring two sets of information for PUSCH to indicate power control parameters (e.g., configuring pathlossReferenceIndex and pathlossReferenceIndex2 simultaneously; or, for example, configuring p0-PUSCH-Alpha and p0-PUSCH-Alpha2 simultaneously).

[0284] Spatial-related information associated with PUSCH, spatial-related information parameters are used to indicate spatial filtering of PUSCH, such as network devices configuring SpatialRelationInfo and / or SpatialRelationInfo2 for PUSCH;

[0285] The TCI state associated with PUSCH is used to indicate the QCL relationship of PUSCH.

[0286] The power control parameters include at least one of the following: a parameter used to indicate the path loss reference signal; a power control parameter p0; or a path loss compensation factor alpha.

[0287] Optionally, determining the target SRS resource set based on the first SRS resource set configured with the first parameter and / or the second SRS resource set configured with the second parameter includes:

[0288] The target SRS resource set is determined based on the first SRS resource set and / or the second SRS resource set, as well as the number of the third parameter.

[0289] Specifically, the terminal can determine the SRS resource set corresponding to PUSCH based on the number of the third parameter.

[0290] The terminal can determine the target SRS resource set based on the number of the third parameter and the number of the first SRS resource set.

[0291] The terminal can also determine the target SRS resource set based on the number of the third parameter, the number of the first SRS resource set, and the number of the second SRS resource set.

[0292] When the number of third parameters configured in the network device is 1, the terminal can use one method to determine the target SRS resource set; when the number of third parameters configured in the network device is multiple, such as 2, the terminal can use another method to determine the target SRS resource set.

[0293] The PUSCH transmission method provided in this application embodiment allows the terminal to determine the target SRS resource set by configuring a first SRS resource set with a first parameter and / or configuring a second SRS resource set with a second parameter, as well as the number of a third parameter. This enables PUSCH to perform M-TRP transmission even when the PUSCH scheduled by DCI format0_1 can only be S-TRP transmission.

[0294] Optionally, the number of the third parameter is X, and the target SRS resource set is determined based on the first SRS resource set and / or the second SRS resource set, and the number of the third parameter, including at least one of the following:

[0295] If the number of sets in the first SRS resource set is greater than X, the target SRS resource set is determined based on the first SRS resource set.

[0296] If the number of sets in the first SRS resource set is equal to X, then the target SRS resource set is determined based on the first SRS resource set.

[0297] If the number of items in the first SRS resource set is less than X, the target SRS resource set is determined based on the SRS resources in the first SRS resource set and other SRS resources outside the first SRS resource set.

[0298] If the number of sets in the second SRS resource set is greater than X and the number of sets in the first SRS resource set is less than X, then the target SRS resource set is determined based on the second SRS resource set.

[0299] If the number of sets in the second SRS resource set is equal to X and the number of sets in the first SRS resource set is less than X, then the target SRS resource set is determined based on the second SRS resource set.

[0300] If the number of sets in the first SRS resource set is less than X, and the number of sets in the second SRS resource set is less than X, then the target SRS resource set is determined based on the first SRS resource set.

[0301] Where X is an integer greater than or equal to 2.

[0302] Specifically, if the number of the third parameter is X, where X is an integer greater than or equal to 2, it indicates that PUSCH is configured for M-TRP transmission. The terminal determines the target SRS resource set based on the number of the third parameter, combined with the number of the first SRS resource set and / or the number of the second SRS resource set.

[0303] Taking PUSCH as an example, with CG Type 1 PUSCH, the first parameter being srs-ResourceSetToAddModList, and the second parameter being srs-ResourceSetToAddModListDCI-0-2, we will explain further.

[0304] If the number of the third parameter is X, where X is an integer greater than or equal to 2, it indicates that the CG Type 1 PUSCH is configured for M-TRP transmission, and the target SRS resource set is determined based on the first SRS resource set and / or the second SRS resource set, and the number of the third parameter, including at least one of the following:

[0305] ① If the number of sets in the first SRS resource set is greater than X, it means that the SRS resources in the first SRS resource set support M-TRP transmission using CG Type 1 PUSCH. The terminal determines the target SRS resource set based on the first SRS resource set. In this case, even if the network device configures other SRS resource sets with a number greater than or equal to X, the terminal can still use the SRS resources in the first SRS resource set for M-TRP transmission.

[0306] ② If the number of sets in the first SRS resource set is equal to X, it means that the SRS resources in the first SRS resource set support M-TRP transmission using CG Type 1 PUSCH, and the terminal determines the target SRS resource set based on the first SRS resource set. In this case, even if the number of sets in other SRS resource sets configured by the network device is greater than or equal to X, the terminal can still use the SRS resources in the first SRS resource set for M-TRP transmission.

[0307] ③ If the number of elements in the first SRS resource set is less than X, it indicates that the SRS resources in the first SRS resource set are insufficient to complete the M-TRP transmission of CG Type 1 PUSCH. The M-TRP transmission of CG Type 1 PUSCH can be performed using SRS resources in the first SRS resource set and other SRS resources outside the first SRS resource set. Optionally, the other SRS resources outside the first SRS resource set can be SRS resources in the second SRS resource set.

[0308] ④ If the number of sets in the second SRS resource set is greater than X, and the number of sets in the first SRS resource set is less than X, it means that the SRS resources in the first SRS resource set are insufficient to complete the M-TRP transmission of CG Type 1 PUSCH, but the SRS resources in the second SRS resource set support the completion of M-TRP transmission of CG Type 1 PUSCH. The terminal can determine the target SRS resource set based on the second SRS resource set.

[0309] ⑤ If the number of sets in the second SRS resource set is equal to X, and the number of sets in the first SRS resource set is less than X, it means that the SRS resources in the first SRS resource set are insufficient to complete the M-TRP transmission of CG Type 1 PUSCH, but the SRS resources in the second SRS resource set support the completion of M-TRP transmission of CG Type 1 PUSCH. The terminal can determine the target SRS resource set based on the second SRS resource set.

[0310] ⑥ If the number of elements in both the first and second SRS resource sets is less than X, it indicates that neither the SRS resources in the first nor the second SRS resource sets are sufficient to complete the M-TRP transmission of CG Type 1 PUSCH. The terminal can determine the target SRS resource set based on the first SRS resource set, or the terminal device can consider this configuration incorrect and not expect the network device to configure X third parameters. For example, the terminal device may use all SRS resources in the first SRS resource set for M-TRP transmission, and also use other SRS resources, such as those in the second SRS resource set, for M-TRP transmission.

[0311] Optionally, the number of third parameters configured by the network device for PUSCH should be less than or equal to the maximum value of the number of the first SRS resource set and the number of the second SRS resource set.

[0312] For example, when the number of sets in the first SRS resource set and the number of sets in the second SRS resource set configured by the network device are both 1, the number of third parameters configured by the network device for PUSCH should not be greater than 1.

[0313] For example, when the number of sets in the first SRS resource set configured by the network device is 3 and the number of sets in the second SRS resource set is 2, the number of third parameters configured by the network device for PUSCH should not be greater than 3.

[0314] The PUSCH transmission method provided in this application embodiment allows the terminal to determine the target SRS resource set by judging the relationship between the first SRS resource set configured by the first parameter and / or the second SRS resource set configured by the second parameter and the number of the third parameter, so that when the PUSCH scheduled by DCI format0_1 can only be S-TRP transmission, the PUSCH can also be M-TRP transmission.

[0315] Optionally, the number of the third parameter is Y, and the target SRS resource set is determined based on the first SRS resource set and / or the second SRS resource set, and the number of the third parameter, including at least one of the following:

[0316] If the number of sets in the first SRS resource set is greater than Y, the target SRS resource set is determined to be Y SRS resource sets in the first SRS resource set;

[0317] If the number of sets in the first SRS resource set is equal to Y, then the target SRS resource set is determined to be Y SRS resource sets in the first SRS resource set.

[0318] If the number of resources in the first SRS resource set is less than Y, the target SRS resource set is determined to be a set consisting of some or all of the SRS resources in the first SRS resource set and other SRS resources outside the first SRS resource set.

[0319] If the number of sets in the second SRS resource set is greater than Y, and the number of sets in the first SRS resource set is less than Y, then the target SRS resource set is determined to be Y SRS resource sets in the second SRS resource set.

[0320] If the number of sets in the second SRS resource set is equal to Y, and the number of sets in the first SRS resource set is less than Y, then the target SRS resource set is determined to be Y SRS resource sets in the second SRS resource set.

[0321] If the number of sets in the first SRS resource set is less than Y, and the number of sets in the second SRS resource set is less than Y, then the target SRS resource set is determined to be the first SRS resource set.

[0322] If the number of sets in the first SRS resource set is less than Y, and the number of sets in the second SRS resource set is less than Y, it is not expected that the network device will be configured with Y third parameters.

[0323] Where Y is an integer greater than or equal to 2.

[0324] Specifically, if the number of the third parameter is Y, where Y is an integer greater than or equal to 2, it indicates that PUSCH is configured for M-TRP transmission. The terminal device determines the target SRS resource set based on the number of the third parameter, combined with the number of the first SRS resource set and / or the second SRS resource set.

[0325] Taking PUSCH as an example, with CG Type 1 PUSCH, the first parameter being srs-ResourceSetToAddModList, and the second parameter being srs-ResourceSetToAddModListDCI-0-2, we will explain further.

[0326] If the number of the third parameter is Y, where Y is an integer greater than or equal to 2, it indicates that the CG Type 1 PUSCH is configured for M-TRP transmission. The target SRS resource set is determined based on the first SRS resource set and / or the second SRS resource set, and the number of the third parameter, including at least one of the following:

[0327] ① If the number of sets in the first SRS resource set is greater than Y, it means that the SRS resources in the first SRS resource set support M-TRP transmission via CG Type 1 PUSCH, and the terminal determines that the target SRS resource set can be Y SRS resource sets in the first SRS resource set.

[0328] ② If the number of SRS resource sets in the first SRS resource set is equal to Y, it means that the SRS resources in the first SRS resource set support M-TRP transmission using CG Type 1 PUSCH. The terminal device determines that the target SRS resource set can be all SRS resource sets in the first SRS resource set, i.e., Y SRS resource sets. In this case, even if the number of other SRS resource sets configured by the network device is greater than or equal to Y, the terminal can still use the SRS resources in the first SRS resource set for M-TRP transmission.

[0329] ③ If the number of elements in the first SRS resource set is less than Y, it indicates that the SRS resources in the first SRS resource set are insufficient to complete the M-TRP transmission of CG Type 1 PUSCH. The M-TRP transmission of CG Type 1 PUSCH can be performed using the first SRS resource set and other SRS resources outside the first SRS resource set. The terminal determines that the target SRS resource set can be a set consisting of some or all of the SRS resources in the first SRS resource set and other SRS resources outside the first SRS resource set. Optionally, the other SRS resources outside the first SRS resource set can be SRS resources in the second SRS resource set.

[0330] ④ If the number of sets in the second SRS resource set is greater than Y, and the number of sets in the first SRS resource set is less than Y, it means that the SRS resources in the first SRS resource set are insufficient to complete the M-TRP transmission of CG Type 1 PUSCH, but the SRS resources in the second SRS resource set support the completion of M-TRP transmission of CG Type 1 PUSCH. The terminal determines that the target SRS resource set can be Y SRS resource sets in the second SRS resource set.

[0331] ⑤ If the number of sets in the second SRS resource set is equal to Y, and the number of sets in the first SRS resource set is less than Y, it means that the SRS resources in the first SRS resource set are insufficient to complete the M-TRP transmission of CG Type 1 PUSCH, but the SRS resources in the second SRS resource set support the completion of M-TRP transmission of CG Type 1 PUSCH. The terminal device determines that the target SRS resource set can be Y SRS resource sets in the second SRS resource set.

[0332] ⑥ If the number of elements in both the first and second SRS resource sets is less than Y, it indicates that neither the SRS resources in the first nor the second SRS resource sets are sufficient to complete the M-TRP transmission for CG Type 1 PUSCH. The terminal determines that the target SRS resource set can be the first SRS resource set, or it can be a set consisting of all or part of the SRS resources in the first SRS resource set and other SRS resources outside the first SRS resource set. Alternatively, the terminal may consider this configuration to be an error, and the terminal device does not expect the network device to configure Y third parameters. For example, the terminal may use all the SRS resources in the first SRS resource set for M-TRP transmission, and also use other SRS resources, such as those in the second SRS resource set, for M-TRP transmission.

[0333] Optionally, the number of third parameters configured by the network device for PUSCH should be less than or equal to the maximum value of the number of the first SRS resource set and the number of the second SRS resource set.

[0334] The PUSCH transmission method provided in this application embodiment involves a terminal determining a target SRS resource set by judging the relationship between the first SRS resource set configured by the first parameter and / or the second SRS resource set configured by the second parameter and the number of the third parameter used to characterize the transmission or reception mode of the PUSCH. This ensures that when the PUSCH scheduled by DCI format0_1 can only be transmitted for S-TRP, the PUSCH can also be transmitted for M-TRP.

[0335] Optionally, the number of the third parameter is 1, and the target SRS resource set is determined based on the first SRS resource set and / or the second SRS resource set, and the number of the third parameter, including:

[0336] The target SRS resource set is determined to be one of the SRS resource sets in the first SRS resource set that meets the preset conditions.

[0337] Specifically, when the number of the third parameter is 1, for example, if p0-PUSCH-Alpha is indicated but p0-PUSCH-Alpha2 is not indicated, it indicates that PUSCH is configured for S-TRP transmission, and the terminal device determines the target SRS resource set as an SRS resource set that meets the preset conditions in the first SRS resource set. The preset conditions can be the SRS resource set with the smallest ID, the SRS resource set with the largest ID, etc.

[0338] For example, when the number of the third parameter is 1, the terminal device determines the SRS resource set with the smallest ID in the first SRS resource set as the target SRS resource set.

[0339] For example, when the number of the third parameter is 1, the terminal device determines the SRS resource set with the largest ID in the first SRS resource set as the target SRS resource set.

[0340] Optionally, the first SRS resource set is the SRS resource set corresponding to DCI format 0_1; and / or

[0341] The second SRS resource set is the SRS resource set corresponding to DCI format 0_2.

[0342] Specifically, the network device configures the SRS resource set for the PUSCH scheduled by DCI format 0_1, which is the first SRS resource set included in the first parameter srs-ResourceSetToAddModList. The network device configures the SRS resource set for the PUSCH scheduled by DCI format 0_2, which is the second SRS resource set included in the second parameter srs-ResourceSetToAddModListDCI-0-2.

[0343] Optionally, the method further includes:

[0344] The maximum number of layers corresponding to PUSCH is determined based on the target layer number parameter. The target layer number parameter is either the first layer number parameter or the second layer number parameter. The first layer number parameter is used to indicate the maximum number of layers corresponding to DCI format 0_1, and the second layer number parameter is used to indicate the maximum number of layers corresponding to DCI format 0_2.

[0345] Specifically, the maximum number of layers that PUSCH can be indicated is the maximum number of layers corresponding to the DCIformat of the SRS resource set corresponding to PUSCH. The first layer number parameter and the second layer number parameter are different parameters, and their values ​​can be the same or different.

[0346] Optionally, when the target SRS resource set is all or part of the SRS resource set in the first SRS resource set, the maximum number of layers corresponding to PUSCH is determined based on a first layer parameter. The first layer parameter indicates the maximum number of layers corresponding to DCI format 0_1, and the maximum number of layers corresponding to PUSCH should not be greater than the maximum number of layers corresponding to DCI format 0_1. The first layer parameter is, for example, maxRank.

[0347] Optionally, when the target SRS resource set is all or part of the SRS resource set in the second SRS resource set, the maximum number of layers corresponding to PUSCH is determined based on a second layer parameter. This second layer parameter indicates the maximum number of layers corresponding to DCI format 0_2, and the maximum number of layers corresponding to PUSCH should not exceed the maximum number of layers corresponding to DCI format 0_2. For example, the second layer parameter is maxRankDCI-0-2-r16.

[0348] Optionally, when the PUSCH is configured for S-TRP transmission or is not configured with target information (e.g., only one precoding and / or layer number is configured, or no second precoding and / or layer number is configured, or only one SRS resource is configured, or no second set of SRS resources is configured, or only one set of power control parameters is configured, or no second set of power control parameters is configured, or only one space-related information parameter is configured, or no second set of space-related information parameters is configured, or only one Transmission Configuration Indicator (TCI) state is configured, or no second set of TCI states is configured), the method for determining the maximum number of layers corresponding to the PUSCH includes: the maximum number of layers corresponding to the PUSCH is determined based on the first layer number parameter.

[0349] Optionally, if the PUSCH is configured for M-TRP transmission or configured with target information (e.g., configured for M-TRP transmission, or configured with two precoding and / or layer numbers, or configured with a second precoding and / or layer number, or configured with two SRS resources, or configured with a second set of SRS resources, or configured with two sets of power control parameters, or configured with a second set of power control parameters, or configured with two spatially related parameters, or configured with a second set of spatially related parameters, or configured with two Transmission Configuration Indicator (TCI) states, or configured with a second set of TCI states), the method for determining the maximum number of layers corresponding to the PUSCH includes at least one of the following:

[0350] ① If the number of sets in the first SRS resource set is M, and M is greater than or equal to 2, the maximum number of layers corresponding to PUSCH is determined based on the first layer number parameter (e.g., maxRank).

[0351] ② If the number of sets in the first SRS resource set is 1, and the number of sets in the second SRS resource set is M, where M is greater than or equal to 2, the maximum number of layers corresponding to PUSCH is determined based on the second layer number parameter (e.g., maxRankDCI-0-2-r16).

[0354] ② If the number of sets in the first SRS resource set is 1, and the number of sets in the second SRS resource set is greater than or equal to M, and M is greater than or equal to 2, the maximum number of layers corresponding to PUSCH is determined based on the second layer number parameter (e.g., maxRankDCI-0-2-r16).

[0355] Optionally, if the network device is configured with maxRankDCI-0-2-r16, when the SRS resource set corresponding to the CG PUSCH transmission is the SRS resource set configured in ResourceSetToAddModList (i.e., the first SRS resource set), the number of layers that the CG PUSCH transmission can indicate is determined according to maxRank in PUSCH-Config, and the number of layers of the CG PUSCH transmission should not be greater than maxRank; when the SRS resource set corresponding to the CG PUSCH transmission is the SRS resource set configured in srs-ResourceSetToAddModListDCI-0-2, the number of layers that the CG PUSCH can indicate is determined according to maxRankDCI-0-2-r16 in PUSCH-Config, and the number of layers of the CG PUSCH transmission should not be greater than maxRankDCI-0-2-r16.

[0356] Optionally, the method further includes:

[0357] The bit width and / or encoding method of the first indication parameter are determined based on the maximum number of layers indicated by the target layer parameter, and / or the bit width and / or encoding method of the second indication parameter are determined based on the maximum number of layers indicated by the target layer parameter. The first indication parameter is used to indicate the SRS resource corresponding to the PUSCH, and the second indication parameter is used to indicate the precoding and / or layer number corresponding to the PUSCH.

[0358] Specifically, the terminal determines the bit width and / or encoding method of the first indication parameter based on the maximum number of layers corresponding to the SRS resource set corresponding to the PUSCH, and / or determines the bit width and / or encoding method of the second indication parameter based on the maximum number of layers corresponding to the SRS resource set corresponding to the PUSCH.

[0359] The first indicator parameter is an SRS resource indicator parameter, used to indicate the SRS resource corresponding to the PUSCH; the second indicator parameter is a precoding and / or layer number indicator parameter, used to indicate the precoding and / or layer number corresponding to the PUSCH. The first indicator parameter is, for example, the parameter `srs-ResourceIndicator` in `rrc-ConfiguredUplinkGrant`, and the second indicator parameter is, for example, the parameter `precodingAndNumberOfLayers` in `rrc-ConfiguredUplinkGrant`.

[0360] Optionally, the method further includes:

[0363] The first indicator parameter is an SRS resource indicator parameter, used to indicate the SRS resource corresponding to PUSCH, such as the parameter srs-ResourceIndicator in rrc-ConfiguredUplinkGrant.

[0364] Optionally, the bit width and / or encoding method of the first indication parameter are determined based on the number of SRS resources included in one SRS resource set in the target SRS resource set. The first indication parameter is used to indicate the SRS resource corresponding to the PUSCH.

[0365] Optionally, the target SRS resource set is a set of SRS resources corresponding to PUSCH during transmission.

[0366] Specifically, after the terminal determines the target SRS resource set corresponding to the PUSCH, the PUSCH can be transmitted using the target SRS resource set or other SRS resources outside the target set during the actual transmission process.

[0367] Optionally, the first SRS resource set and / or the second SRS resource set are SRS resource sets corresponding to the transmission mode of PUSCH.

[0368] Specifically, the first SRS resource set and / or the second SRS resource set are SRS resource sets corresponding to the transmission mode of PUSCH. The transmission mode of PUSCH is either codebook or non-codebook.

[0369] For example, when PUSCH is configured for codebook-based transport, a CG Type 1 PUSCH transport corresponds to an SRS resource set whose purpose type is configured as "codebook" included in srs-ResourceSetToAddModList or srs-ResourceSetToAddModListDCI-0-2.

[0370] For example, when PUSCH is configured for non-codebook-based transport, a CG Type 1 PUSCH transport corresponds to an SRS resource set included in srs-ResourceSetToAddModList or srs-ResourceSetToAddModListDCI-0-2 whose usage type is configured as "nonCodebook".

[0371] Optionally, the maximum value of the number of sets in the first SRS resource set and the number of sets in the second SRS resource set is greater than or equal to the number of third parameters configured by the network device for PUSCH.

[0376] For example, PUSCH scheduled by DCI format 0_0, PUSCH scheduled by DCI format 0_1, PUSCH scheduled by DCI format 0_2, etc.

[0377] Optionally, the PUSCH transmission method provided in this application embodiment can be applied to repeatedly transmitted PUSCH, such as PUSCH repeatedly transmitted in multiple sub-slots in the 3GPP NR system, i.e., PUSCH with repetition type B repetition scheme; or PUSCH repeatedly transmitted in multiple slots in the 3GPP NR system, i.e., PUSCH with repetition type A repetition scheme.

[0378] Optionally, the PUSCH transmission method provided in this application embodiment can also be applied to non-repeating PUSCH, or to PUSCH that is repeatedly transmitted in the frequency domain, or to PUSCH that is repeatedly transmitted in the spatial domain.

[0379] The PUSCH transmission method provided in this application embodiment allows the terminal to determine one or more SRS resource sets corresponding to the PUSCH based on whether the network device has configured target information for the PUSCH, or based on the number of third parameters configured by the network device, combined with the number of sets of the first SRS resource set and / or the number of sets of the second SRS resource set, so that when the PUSCH scheduled by DCIformat0_1 can only be transmitted for S-TRP, the PUSCH can also be transmitted for M-TRP.

[0447] Optionally, the number of the third parameter is 1, and there is a correspondence between the target SRS resource set and the first SRS resource set configured by the first parameter and / or the second SRS resource set configured by the second parameter, including:

[0448] The target SRS resource set is an SRS resource set that meets the preset conditions in the first SRS resource set.

The first number of layers parameter is used to indicate the maximum number of layers corresponding to DCI format 0_1, and the second number of layers parameter is used to indicate the maximum number of layers corresponding to DCI format 0_2.

[0452] Specifically, when the target SRS resource set is all or part of the SRS resource set in the first SRS resource set, the network device determines the target layer number parameter as the first layer number parameter, which is used to indicate the maximum layer number corresponding to DCI format 0_1.

[0453] When the target SRS resource set is all or part of the SRS resource set in the second SRS resource set, the network device determines the target layer number parameter as the second layer number parameter.

[0457] Optionally, the bit width and / or encoding method of the SRS resource indication information are determined based on the number of SRS resources in the target SRS resource set.

[0458] Optionally, the network device transmits PUSCH according to the SRS resource indication information.

[0459] The relevant methods and preset conditions provided in this application can be found in the above method embodiments, and will not be repeated here.

[0460] The technical solutions of the embodiments of this application are further described below through several specific examples.

[0461] Example 1:

[0462] For CG Type 1 PUSCH, when the PUSCH transmission is configured as codebook / non-codebook, for example, when the parameter txConfig in PUSCH-ConfigIE is configured as "Codebook" / "nonCodebook", the PUSCH transmission method includes at least one of the following:

[0463] Case 1: When `rrc-ConfiguredUplinkGrant` in `ConfiguredGrantConfig` specifies `pathlossReferenceIndex2`:

[0464] ① If srs-ResourceSetToAddModList includes two SRS resource sets whose usage is configured as "codebook" / "non-codebook", then CG Type 1 PUSCH corresponds to the two SRS resource sets included in the higher-level parameter srs-ResourceSetToAddModList whose usage is configured as "codebook" / "non-codebook".

[0465] ② If srs-ResourceSetToAddModList includes one SRS resource set whose purpose is configured as "codebook" / "non-codebook", and srs-ResourceSetToAddModListDCI-0-2 includes two SRS resource sets whose purpose is configured as "codebook" / "non-codebook", then the CG Type 1 PUSCH transmission corresponds to the two SRS resource sets whose purpose is configured as "codebook" / "non-codebook" included in the higher-layer parameter srs-ResourceSetToAddModListDCI-0-2.

[0466] ③ When srs-ResourceSetToAddModList includes one SRS resource set whose purpose is configured as "codebook" / "non-codebook", and srs-ResourceSetToAddModListDCI-0-2 includes one SRS resource set whose purpose is configured as "codebook" / "non-codebook", this configuration can be considered an error case. The UE does not expect pathlossReferenceIndex2 / precodingAndNumberOfLayers2 / srs-ResourceIndicator2 to be configured in rrc-ConfiguredUplinkGrant IE in ConfiguredGrantConfig.

[0467] Case 2: When pathlossReferenceIndex2 is not specified in ConfiguredGrantConfig:

[0468] CG Type 1 PUSCH transport corresponds to multiple SRS resource sets included in the higher-level parameter srs-ResourceSetToAddModList, whose purpose is configured as "codebook" / "non-codebook".

[0469] Case 3: When the rrc-ConfiguredUplinkGrant IE in ConfiguredGrantConfig includes two parameters used to indicate the path loss reference signal (e.g., indicating pathlossReferenceIndex and pathlossReferenceIndex2):

[0470] ① If srs-ResourceSetToAddModList includes two SRS resource sets whose purpose is configured as "codebook" / "non-codebook", then CG Type 1 PUSCH corresponds to the two SRS resource sets whose purpose is configured as "codebook" / "non-codebook" included in the higher-level parameter srs-ResourceSetToAddModList.

[0471] ② If srs-ResourceSetToAddModList includes one SRS resource set whose purpose is configured as "codebook" / "non-codebook", and srs-ResourceSetToAddModListDCI-0-2 includes two SRS resource sets whose purpose is configured as "codebook" / "non-codebook", then the CG Type 1 PUSCH transmission corresponds to the two SRS resource sets whose purpose is configured as "codebook" / "non-codebook" included in the higher-layer parameter srs-ResourceSetToAddModListDCI-0-2.

[0472] ③ If srs-ResourceSetToAddModList includes one SRS resource set whose purpose is configured as "codebook" / "non-codebook", and srs-ResourceSetToAddModListDCI-0-2 includes one SRS resource set whose purpose is configured as "codebook" / "non-codebook", this configuration can be considered an error, or the UE does not expect to include two parameters in ConfiguredGrantConfig to indicate p0 and / or alpha.

[0473] ④ When srs-ResourceSetToAddModList includes one SRS resource set whose purpose is configured as "codebook" / "non-codebook", and srs-ResourceSetToAddModListDCI-0-2 includes one SRS resource set whose purpose is configured as "codebook" / "non-codebook", then CG Type 1 PUSCH transmission corresponds to one SRS resource set whose purpose is configured as "codebook" / "non-codebook" included in the higher-level parameter srs-ResourceSetToAddModList. In this case, CG Type 2 PUSCH can only perform S-TRP transmission.

[0474] Case 4: When the rrc-ConfiguredUplinkGrant IE in ConfiguredGrantConfig includes one parameter to indicate the path loss reference signal (e.g., indicating pathlossReferenceIndex, but not pathlossReferenceIndex2):

[0475] A CG Type 1 PUSCH transfer corresponds to an SRS resource set (e.g., the SRS resource set with the lowest ID) included in the higher-level parameter srs-ResourceSetToAddModList, whose purpose is configured as "codebook" / "non-codebook".

[0476] Example 2:

[0477] For CG Type 2 PUSCH, when the PUSCH transmission is configured as codebook / non-codebook, for example, when the parameter txConfig in PUSCH-ConfigIE is configured as "Codebook" / "nonCodebook", the PUSCH transmission method includes at least one of the following:

[0478] Case 1: When p0-PUSCH-Alpha2 is specified in ConfiguredGrantConfig:

[0479] ① If srs-ResourceSetToAddModList includes two SRS resource sets whose purpose is configured as "codebook" / "non-codebook", then CG Type 2 PUSCH corresponds to the two SRS resource sets whose purpose is configured as "codebook" / "non-codebook" included in the higher-level parameter srs-ResourceSetToAddModList.

[0480] ② If srs-ResourceSetToAddModList includes one SRS resource set whose purpose is configured as "codebook" / "non-codebook", and srs-ResourceSetToAddModListDCI-0-2 includes two SRS resource sets whose purpose is configured as "codebook" / "non-codebook", then the CG Type 2 PUSCH transmission corresponds to the two SRS resource sets whose purpose is configured as "codebook" / "non-codebook" included in the higher-level parameter srs-ResourceSetToAddModListDCI-0-2.

[0481] ③ If srs-ResourceSetToAddModList includes one SRS resource set whose purpose is configured as "codebook" / "non-codebook", and srs-ResourceSetToAddModListDCI-0-2 includes one SRS resource set whose purpose is configured as "codebook" / "non-codebook", this configuration can be considered an error, or the UE does not expect p0-PUSCH-Alpha2 to be included in ConfiguredGrantConfig.

[0482] Case 2: When p0-PUSCH-Alpha2 is not specified in ConfiguredGrantConfig:

[0483] CG Type 2 PUSCH transport corresponds to multiple SRS resource sets included in the higher-level parameter srs-ResourceSetToAddModList, whose purpose is configured as "codebook" / "non-codebook".

[0484] Case 3: When ConfiguredGrantConfig includes two parameters to indicate p0 and / or alpha (e.g., indicating both p0-PUSCH-Alpha and p0-PUSCH-Alpha2):

[0485] ① If srs-ResourceSetToAddModList includes two SRS resource sets whose purpose is configured as "codebook" / "non-codebook", then CG Type 2 PUSCH corresponds to the two SRS resource sets whose purpose is configured as "codebook" / "non-codebook" included in the higher-level parameter srs-ResourceSetToAddModList.

[0486] ② If srs-ResourceSetToAddModList includes one SRS resource set whose purpose is configured as "codebook" / "non-codebook", and srs-ResourceSetToAddModListDCI-0-2 includes two SRS resource sets whose purpose is configured as "codebook" / "non-codebook", then the CG Type 2 PUSCH transmission corresponds to the two SRS resource sets whose purpose is configured as "codebook" / "non-codebook" included in the higher-level parameter srs-ResourceSetToAddModListDCI-0-2.

[0487] ③ If srs-ResourceSetToAddModList includes one SRS resource set whose purpose is configured as "codebook" / "non-codebook", and srs-ResourceSetToAddModListDCI-0-2 includes one SRS resource set whose purpose is configured as "codebook" / "non-codebook", this configuration can be considered an error, or the UE does not expect to include two parameters in ConfiguredGrantConfig to indicate p0 and / or alpha.

[0488] ④ When srs-ResourceSetToAddModList includes one SRS resource set whose purpose is configured as "codebook" / "non-codebook", and srs-ResourceSetToAddModListDCI-0-2 includes one SRS resource set whose purpose is configured as "codebook" / "non-codebook", then the CG Type 2 PUSCH transmission corresponds to one SRS resource set whose purpose is configured as "codebook" / "non-codebook" included in the higher-level parameter srs-ResourceSetToAddModList. In this case, CG Type 2 PUSCH can only perform S-TRP transmission.

[0489] Case 4: When ConfiguredGrantConfig includes a parameter that indicates p0 and / or alpha (e.g., p0-PUSCH-Alpha is indicated, but p0-PUSCH-Alpha2 is not), the CG Type 2 PUSCH transfer corresponds to one SRS resource set (e.g., the SRS resource set with the lowest ID) included in the higher-level parameter srs-ResourceSetToAddModList, whose purpose is configured as "codebook" / "non-codebook".

[0490] Example 3:

[0491] For CG Type 1 PUSCH, if maxRankDCI-0-2-r16 and maxRank are configured, when the SRS resource set corresponding to the CG Type 1 PUSCH transmission is the SRS resource set configured in ResourceSetToAddModList, the number of transmission layers for CG Type 1 PUSCH should not exceed maxRank; when the SRS resource set corresponding to the CG PUSCH transmission is the SRS resource set configured in srs-ResourceSetToAddModListDCI-0-2, the number of transmission layers for CG Type 1 PUSCH should not exceed maxRankDCI-0-2-r16.

[0492] If maxRank is configured but maxRankDCI-0-2-r16 is not configured, the number of transport layers for CG Type 1 PUSCH should not be greater than maxRank.
