Description

Data sending and receiving device and method Technical Field

[0001] The embodiments of the present application relate to the field of communication technologies. Background Art

[0002] During the standardization process of Release 17 (Rel-17), the 3GPP standardization organization carried out standardization-related work on the unified transmission configuration indication (TCI). Among them, unified TCI includes single TRP (sTRP) unified TCI, that is, there is one TCI state in one transmission direction, corresponding to one TRP, and multiple TRP (mTRP) unified TCI, that is, there are two TCI states in one transmission direction, corresponding to two TRPs.

[0003] In previous standardization work, the transmission of the physical downlink shared channel (PDSCH), physical downlink control channel (PDCCH), physical uplink shared channel (PUSCH), and physical uplink control channel (PUCCH) based on mTRP was standardized. Among them, mTRP transmission includes mTRP transmission based on single DCI (sDCI) and mTRP transmission based on multiple DCI (mDCI).

[0004] Currently, 3GPP is standardizing simultaneous transmission multi-panel (STxMP) in Rel-18. STxMP is designed based on the mTRP unified TCI framework.

[0005] It should be noted that the above introduction to the technical background is only for the convenience of providing a clear and complete description of the technical solutions of this application and for the convenience of understanding by those skilled in the art. It cannot be considered that the above technical solutions are well known to those skilled in the art simply because these solutions are explained in the background technology part of this application.

[0006] Summary of the Invention

[0007] In Rel-18, standardization work on STxMP based on mTRP (single DCI) will continue. For STxMP, PUSCH transmission based on STxMP may include different specific transmission schemes, such as: simultaneous multi-panel transmission (STxMP) spatial division multiplexing (SDM) scheme, simultaneous multi-panel transmission (STxMP) single frequency network (SFN) scheme, etc. In addition, when the terminal device is configured with STxMP, the terminal device may also use the sTRP scheme or time division multiplexing (TDM) scheme to send uplink data.

[0008] STxMP supports uplink data transmission based on dynamic authorization and configured authorization. For traditional configured authorization, such as the configured authorization before the introduction of Rel-18 STxMP, the terminal device can use the configured grant (CG) to send uplink data (for example, the uplink data is PUSCH or UL-SCH). In the configuration of the configured authorization, the terminal device is pre-configured with the configured grant occasion, which is always reserved for possible uplink transmission. When there is uplink data to be sent, the terminal device can independently select the configured grant occasion to send it. Since there is no need to wait for uplink scheduling from the network device, the configured authorization can achieve faster uplink transmission. For example, the configured authorization includes configured grant Type 1 (configured grant Type 1) and configured grant Type 2 (configured grant Type 2). After the Radio Resource Control (RRC) signaling configures the configured grant type 1, the terminal device can use the configured grant occasion for uplink transmission. After the RRC signaling configures the configuration authorization type 2, it needs to be activated through downlink control information (DCI) before the terminal device can use the configuration authorization opportunity for uplink transmission.

[0009] In Rel-18, the terminal device can perform STxMP transmission based on the configuration authorization. For example, the terminal device is configured with two transmission precoding matrix indication information (TPMI, Transmission Precoding Matrix Indicator) and / or SRS resource indication information (SRI, SRS Resource Indicator), and the terminal device uses the two TPMIs and / or SRIs to send configured grant Type 1 PUSCH to two TRPs respectively.

[0010] The inventors found that for the configured grant Type 1 PUSCH under mTRP unified TCI, it can be configured with two TPMIs and / or two SRIs, and can be configured to apply the first TCI state and / or the second TCI state. It can also be configured to use the SDM scheme or the SFN scheme, etc., thereby generating a variety of possible configuration combinations.

[0011] For some specific configuration combinations, there is still undefined device behavior in how to transmit the configured grant Type 1 PUSCH: for example, when the terminal device is configured to apply the first TCI sate or the second TCI state, which of the two TPMI and / or SRI should the terminal device use is a technical problem that needs to be solved; for example, when the terminal device is configured to use the SDM scheme, how the terminal device determines which phase tracking reference signal (PT-RS) ports are actually applied, and how to determine which demodulation reference signal (DMRS) port an actually applied phase tracking reference signal (PT-RS) port is associated with are technical problems that need to be solved.

[0012] If the above technical problem is not resolved, the terminal device and the network device may have inconsistent understandings of the configuration parameters actually used for configured grant Type 1 PUSCH transmission, resulting in uplink data transmission failure.

[0013] To address at least one of the above issues, embodiments of the present application provide a data transmission and data reception apparatus and method. When a terminal device is configured to transmit a PUSCH using the first TCI state or the second TCI state, the terminal device transmits the PUSCH based on the first TPMI and / or the first SRI. This avoids ambiguity between the terminal device and the network device regarding the transmission parameters actually applied to the configured grant Type 1 PUSCH, thereby avoiding PUSCH transmission failures and enabling reliable transmission of uplink data.

[0014] According to one aspect of an embodiment of the present application, a data sending method is provided, which is applied to a terminal device, and the method includes:

[0015] The first transmission configuration indication state (TCI state) and / or the second transmission configuration indication state (TCI state) are configured to apply;

[0017] In which, when the first transmission configuration indication state (TCI state) or the second transmission configuration indication state (TCI state) is configured to send the PUSCH, the PUSCH is sent according to the first transmission precoding matrix indication information (TPMI, Transmission Precoding Matrix Indicator) and / or the first SRS resource indication information (SRI, SRS Resource Indicator).

[0018] According to another aspect of an embodiment of the present application, a data receiving method is provided, which is applied to a network device, and the method includes:

[0019] Configuring the terminal device to apply a first transmission configuration indication state (TCI state) and / or a second transmission configuration indication state (TCI state);

[0021] According to another aspect of an embodiment of the present application, a data sending apparatus is provided, configured in a terminal device, wherein the data sending apparatus includes:

[0022] a first configuration unit configured to apply a first transmission configuration indication state (TCI state) and / or a second transmission configuration indication state (TCI state);

[0023] a sending unit configured to send a physical uplink shared channel (PUSCH) corresponding to a configuration grant type 1 according to the first transmission configuration indication state (TCI state) and / or the second transmission configuration indication state (TCI state);

[0024] In which, when the first configuration unit is configured to apply the first transmission configuration indication state (TCI state) or the second transmission configuration indication state (TCI state) to send the physical uplink shared channel (PUSCH), the sending unit sends the physical uplink shared channel (PUSCH) according to the first transmission precoding matrix indication information (TPMI) and / or the first SRS resource indication information (SRI).

[0025] According to another aspect of an embodiment of the present application, a data receiving device is provided, configured in a network device, the data receiving device comprising:

[0026] a second configuration unit configured to configure the terminal device to apply a first transmission configuration indication state (TCI state) and / or a second transmission configuration indication state (TCI state);

[0028] One of the beneficial effects of the embodiments of the present application is that, when a terminal device is configured to transmit a PUSCH using the first TCI state or the second TCI state, the terminal device transmits the PUSCH according to the first TPMI and / or the first SRI. This avoids ambiguity between the terminal device and the network device regarding the transmission parameters actually applied to the configured grant Type 1 PUSCH, thereby avoiding PUSCH transmission failure and enabling reliable transmission of uplink data.

[0056] The following describes the scenarios of the embodiments of the present application through examples, but the present application is not limited thereto.

[0057] Figure 1 is a schematic diagram of a communication system according to an embodiment of the present application, and Figure 2 is another schematic diagram of a communication system according to an embodiment of the present application. Figures 1 and 2 schematically illustrate a situation using a terminal device and a network device as an example. As shown in Figures 1 and 2, communication system 100 may include a first TRP 101, a second TRP 102, and a terminal device 103. The first TRP 101 and the second TRP 102 may be network devices. For simplicity, Figures 1 and 2 illustrate only two network devices and one terminal device as an example, but the embodiments of the present application are not limited thereto.

[0058] In the embodiment of the present application, existing services or future services can be transmitted between the first TRP 101, the second TRP 102, and the terminal device 103. For example, these services may include but are not limited to: enhanced mobile broadband (eMBB), massive machine type communication (mMTC), and ultra-reliable and low-latency communication (URLLC), etc.

[0059] Rel-16 standardized PDSCH transmission based on mTRP, and Rel-17 standardized PDCCH, PUSCH, and PUCCH transmission based on mTRP. mTRP transmission includes mTRP transmission based on sDCI (single DCI) and mTRP transmission based on mDCI (multiple DCI). For sDCI mTRP, one DCI schedules the uplink and downlink transmissions of two TRPs, which is more suitable for situations where the backhaul between TRPs is ideal. For mDCI mTRP, two TRPs use two DCIs to schedule the uplink and downlink transmissions of their respective TRPs, which is more suitable for situations where the backhaul between TRPs is not ideal.

[0060] Standardization work on STxMP will continue in Rel-18. STxMP is based on the mTRP unified TCI framework.

[0061] In mTRP unified TCI, for a particular transmission direction (uplink or downlink), the terminal device maintains two TCI states. These two TCI states are called indicated TCI states and are indicated by the network device through the MAC Control Element (MAC CE) and / or DCI.

[0062] FIG1 shows an example of uplink and downlink links in the mTRP scenario according to an embodiment of the present application; FIG2 shows another example of uplink and downlink links in the mTRP scenario according to an embodiment of the present application.

[0063] In the unified TCI solution under the mTRP scenario in Rel-18, for the terminal device 103 (UE 103), there is a downlink and an uplink corresponding to each TRP, and there are a total of 4 links between the UE and the two TRPs. For example, there is a downlink (hereinafter referred to as the first downlink) and an uplink (hereinafter referred to as the first uplink) between UE 103 and the first TRP 101, and there is a downlink (hereinafter referred to as the second downlink) and an uplink (hereinafter referred to as the second uplink) between UE 103 and the second TRP 102 to provide QCL references for the transmission of their corresponding links.

[0064] In mTRP transmission, when the high-level parameter unifiedTCI-StateType takes the value of 'separate', as shown in Figure 1, the TCI states corresponding to the above four links are {first downlink TCI state (DL TCI state 1), second downlink TCI state (DL TCI state 2), first uplink TCI state (UL TCI state 1), second uplink TCI state (UL TCI state 2)}, which can provide QCL references for the first downlink, second downlink, first uplink, and second uplink, respectively.

[0065] In mTRP transmission, when the high-level parameter unifiedTCI-StateType takes the value of 'joint', as shown in Figure 2, the TCI states corresponding to the above four links are {first joint TCI state (Joint TCI state 1), second joint TCI state (Joint TCI state 2)}, where the first joint TCI state can provide QCL reference for the first downlink and the first uplink, and the second joint TCI state can provide QCL reference for the second downlink and the second uplink.

[0066] Therefore, for uplink transmission, the two indicated TCI states are "first uplink TCI state and second uplink TCI state", or "first combined TCI state and second combined TCI state"; for downlink transmission, the two indicated TCI states are "first downlink TCI state and second downlink TCI state", or "first combined TCI state and second combined TCI state".

[0067] For certain channels or signals, such as PDCCH, PUCCH, configured grant, etc., the terminal device can be configured to use "the first TCI state, or the second TCI state", or to use "the first TCI state and the second TCI state".

[0068] In the sDCI mTRP scenario, STxMP PUSCH transmission supports the STxMP SDM scheme and the STxMP SFN scheme.

[0069] FIG3 is a schematic diagram of sending a PUSCH according to the STxMP SDM scheme according to an embodiment of the present application; FIG4 is a schematic diagram of sending a PUSCH according to the STxMP SFN scheme according to an embodiment of the present application.

[0070] For example, in the mTRP scenario, the terminal device is configured with two panels to send PUSCH to the first TRP101 and the second TRP102 respectively.

[0071] As shown in Figure 3, when the terminal device sends uplink data according to the STxMP SDM scheme, the uplink data (UL-SCH 1) is carried by PUSCH 1, and the uplink data (UL-SCH 1) is divided into two parts, for example, called the first part of uplink data (1st part of UL-SCH 1) and the second part of uplink data (2nd part of UL-SCH 1); for example, the first part of uplink data (1st part of UL-SCH 1) is sent on the first panel, and the second part of uplink data (2nd part of UL-SCH 1) is sent on the second panel. The first part of uplink data (1st part of UL-SCH 1) and the second part of uplink data (2nd part of UL-SCH 1) are sent on the same time-frequency resources, may have different numbers of layers, and may correspond to different DMRS ports.

[0072] As shown in Figure 4, when the terminal device sends uplink data according to the STxMP SFN scheme, uplink data 1 (UL-SCH 1) is carried by PUSCH 1, and uplink data 1 (UL-SCH 1) is divided into two copies and sent through the first panel and the second panel respectively. The content sent on each panel is UL-SCH 1. For example, the (UL-SCH 1) sent on the first panel and the second panel occupies the same time-frequency resources, has the same number of layers, and uses the same DMRS port.

[0073] For PUSCH transmission, in addition to using the above-mentioned SDM scheme and SFN scheme, the terminal device can also use the sTRP scheme for uplink transmission. Figure 5 is a schematic diagram of an embodiment of the present application sending PUSCH according to the sTRP scheme. For example, as shown in Figure 5, the terminal device sends PUSCH to a TRP. As the most traditional PUSCH transmission scheme, the standardization of the sTRP scheme began in Rel-15.

[0074] For PUSCH transmission, in addition to using the above-mentioned SDM scheme and SFN scheme, the terminal device can also use the TDM scheme for uplink transmission. Figure 6 is a schematic diagram of an embodiment of the present application sending PUSCH according to the TDM scheme. For example, as shown in Figure 6, the terminal device sends PUSCH to the first TRP at the first uplink transmission opportunity, sends PUSCH to the second TRP at the second uplink transmission opportunity, and so on. Rel-17 standardizes the TDM scheme.

[0075] STxMP supports uplink data transmission based on dynamic authorization and configured authorization. For traditional configured authorization, such as the configured authorization before the introduction of Rel-18 STxMP, the terminal device can use the configured grant (CG) to send uplink data (for example, the uplink data is PUSCH or UL-SCH). In the configuration of the configured authorization, the terminal device is pre-configured with the configured grant occasion, which is always reserved for possible uplink transmission. When there is uplink data to be sent, the terminal device can independently select the configured grant occasion to send it. Since there is no need to wait for uplink scheduling from the network device, the configured authorization can achieve faster uplink transmission. For example, the configured authorization includes configured grant Type 1 (configured grant Type 1) and configured grant Type 2 (configured grant Type 2). After the Radio Resource Control (RRC) signaling configures the configured grant type 1, the terminal device can use the configured grant occasion for uplink transmission. After the RRC signaling configures the configuration authorization type 2, it needs to be activated through downlink control information (DCI) before the terminal device can use the configuration authorization opportunity for uplink transmission.

[0076] In Rel-18, the terminal device can perform STxMP transmission based on the configuration authorization. For example, the terminal device is configured with two transmission precoding matrix indication information (TPMI, Transmission Precoding Matrix Indicator) and / or SRS resource indication information (SRI, SRS Resource Indicator), and the terminal device uses the two TPMIs and / or SRIs to send configured grant Type 1 PUSCH to two TRPs respectively.

[0077] The inventors found that for the configured grant Type 1 PUSCH under mTRP unified TCI, it can be configured with two TPMIs and / or two SRIs, and can be configured to apply the first TCI state and / or the second TCI state, and can also be configured to use the SDM scheme or the SFN scheme, thereby generating a variety of possible configuration combinations.

[0078] For some specific configuration combinations, there is still undefined device behavior in how to transmit configured grant Type 1 PUSCH: for example, when the terminal device is configured to apply the first TCI state or the second TCI state, which of the two TPMI and / or SRI should the terminal device use is a technical problem that needs to be solved; for example, when the terminal device is configured to use the SDM solution, how the terminal device determines which phase tracking reference signal (PT-RS) ports are actually applied, and how to determine which demodulation reference signal (DMRS) port an actually applied phase tracking reference signal (PT-RS) port is associated with is a technical problem that needs to be solved. If the above technical problems are not solved, the terminal device and the network equipment will have inconsistent understandings of the configuration parameters actually used for configured grant Type 1 PUSCH transmission, resulting in uplink data transmission failure.

[0079] To address at least one of the above problems, embodiments of the present application provide a data sending and receiving device and method.

[0080] Embodiments of the first aspect

[0081] An embodiment of the present application provides a data sending method, which is applied on a terminal device side.

[0082] FIG7 is a schematic diagram of a data transmission method according to an embodiment of the present application. As shown in FIG7 , the method includes:

[0083] 701, the terminal device is configured to apply a first transmission configuration indication state (TCI state) and / or a second transmission configuration indication state (TCI state);

[0084] 702. The terminal device sends a PUSCH corresponding to the configured authorization type 1 according to the first transmission configuration indication state (TCI state) and / or the second transmission configuration indication state (TCI state); wherein, when the first transmission configuration indication state (TCI state) or the second transmission configuration indication state (TCI state) is configured to send the PUSCH, the PUSCH is sent according to the first transmission precoding matrix indication information (TPMI, Transmission Precoding Matrix Indicator) and / or the first SRS resource indication information (SRI, SRS Resource Indicator).

[0085] This can avoid ambiguity between the terminal device and the network device in understanding the transmission parameters actually applied to the configured grant Type 1 PUSCH, thereby avoiding PUSCH transmission failure and achieving reliable transmission of uplink data.

[0086] It is worth noting that FIG7 above is merely a schematic illustration of an embodiment of the present application, using a terminal device as an example, but the present application is not limited thereto. For example, the execution order of the various operations may be appropriately adjusted, other operations may be added or some operations may be reduced, and the objects of the aforementioned operations may be adjusted. Those skilled in the art may make appropriate modifications based on the above description, and are not limited to the description of FIG7 above.

[0087] In some embodiments, the "first TCI state" and the "second TCI state" include one of the "uplink TCI state", the "joint TCI state", and the "downlink TCI state"; the "uplink TCI state", the "joint TCI state", and the "downlink TCI state" can be indicated by the "joint DL / UL TCI state" or the "separate DL / UL TCI state"; the "DL TCI state" can be the "DL only TCI state" or the "joint TCI state"; the "UL TCI state" can be the "UL only TCI state" or the "joint TCI state". The above is only an exemplary description, and the embodiments of the present application are not limited to this.

[0088] In some embodiments, a TCI state is equivalent to at least one of the following: a panel; a transmission reception point (TRP); an SRS resource set; or a CORESET set. For example, "the terminal device is configured to apply the first transmission configuration indication state (TCI state) or the second transmission configuration indication state (TCI state) to send" is equivalent to "the terminal device is configured to apply the first panel or the second panel to send," etc., and the examples are not listed here.

[0089] In some embodiments, configured grant Type 1 (configured grant Type 1) can be replaced with type 1 configured grant (Type 1 configured grant); "PUSCH corresponding to configured grant Type 1" can be replaced with (PUSCH corresponding to configured grant Type 1); RRC parameters can be replaced with higher-layer parameters; TPMI can be replaced with "TPMI and rank"; PT-RS refers to uplink PT-RS; DM-RS refers to uplink DM-RS, etc. This application does not limit this.

[0090] In some implementations, "PUSCH" corresponds to (is equivalent to) "uplink data" corresponds to (is equivalent to) "UL-SCH", etc., and this application does not limit this.

[0091] In some implementations, "one TRP" is associated with "one SRS resource set," "one UL TCI state," "one SRS resource," "one TPMI," and "one uplink transmission." For example, for Rel-18 STxMP, one panel can be associated with one TRP, which in turn can be associated with one SRS resource set, one TCI state, one SRS resource, one TPMI, and one uplink transmission.

[0092] For example, the terms "TRP" and "SRS resource set" are interchangeable; the terms "TRP" and "CSI-RS resource set" are interchangeable; the terms "corresponding," "associated," and "including" are interchangeable; and the terms "PUSCH," "PUSCH transmission," and "PUSCH sending" are interchangeable.

[0093] In some embodiments, the terminal device further receives first configuration information. For example, the first configuration information is "ConfiguredGrantConfig", where the "ConfiguredGrantConfig" may include a parameter "rrc-ConfiguredUplinkGrant", where both "rrc-ConfiguredUplinkGrant" and "ConfiguredGrantConfig" are RRC parameters.

[0094] In some embodiments, the terminal device may be configured by the first configuration information to apply the first TCI state and / or the second TCI state to send a PUSCH configured with grant type 1.

[0095] For example, the terminal device is configured by the field "applyIndicatedTCIState" in the RRC parameter "ConfiguredGrantConfig" to apply the first TCI state and / or the second TCI state to send a PUSCH configured with grant type 1. For example, the field "applyIndicatedTCIState" can be configured in "ConfiguredGrantConfig" or "rrc-ConfiguredUplinkGrant".

[0096] Table 1 is an example of the field “applyIndicatedTCIState” in the RRC parameter “ConfiguredGrantConfig” of this application.

[0097] Table 1

[0098] For example, Table 1 "ConfiguredGrantConfig" corresponds to the first configuration information of this application, and the field "applyIndicatedTCIState" can take the values ​​of "the first", "the second", or "both".

[0099] For example, when the value in the field "applyIndicatedTCIState" is configured as "the first", it indicates that the terminal device applies the first TCI state; when the value in the field "applyIndicatedTCIState" is configured as "the second", it indicates that the terminal device applies the second TCI state; when the value in the field "applyIndicatedTCIState" is configured as "both", it indicates that the terminal device applies the first TCI state and the second TCI state; thus, through the first configuration information, the terminal device is configured to apply the first TCI state and / or the second TCI state.

[0100] In some embodiments, when the terminal device is configured to apply the first TCI state or the second TCI state to send a PUSCH configured with authorization type 1, when the terminal device is configured to apply the first TCI state to send PUSCH, the terminal device sends PUSCH according to the first TPMI and / or the first SRI; when the terminal device is configured to apply the second TCI state to send PUSCH, the terminal device still sends PUSCH according to the first TPMI and / or the first SRI.

[0101] For example, the "first TPMI and / or first SRI" is one of two TPMIs and / or two SRIs configured for the terminal device, where the two TPMIs and / or two SRIs configured for the terminal device correspond to the first TCI state and the second TCI state, respectively. For example, the "first TPMI and / or first SRI" of the two TPMIs and / or two SRIs may be predefined as the "first TPMI and / or first SRI," or the "second TPMI and / or second SRI" of the two TPMIs and / or two SRIs may be predefined as the "first TPMI and / or first SRI," and so on. This application does not limit this.

[0102] In some embodiments, the PUSCH includes a non-codebook based PUSCH or a codebook based PUSCH.

[0103] For example, for codebook-based PUSCH transmission, the terminal device sends PUSCH according to the "first TPMI and the first SRI"; for non-codebook-based PUSCH transmission, the terminal device sends PUSCH according to the first SRI; and for the relevant content of "non-codebook-based PUSCH, codebook-based PUSCH", reference can be made to the prior art, and this application is not limited to this.

[0104] In some embodiments, when the terminal device is configured to apply the first transmission configuration indication state (TCI state) or the second transmission configuration indication state (TCI state) to send the PUSCH: the first transmission precoding matrix indication information (TPMI) is configured by a first parameter (precodingAndNumberOfLayers), and / or the first SRS resource indication information (SRI) is configured by a second parameter (srs-ResourceIndicator).

[0105] For example, when the value of the field "applyIndicatedTCIState" in the aforementioned first configuration information is configured as "the first" or "the second", the terminal device sends PUSCH according to the first TPMI and / or the first SRI, wherein the first TPMI is configured through the RRC parameter: the first parameter (precodingAndNumberOfLayers), and the first SRI is configured through the RRC parameter: the second parameter (srs-ResourceIndicator).

[0106] In some embodiments, when the terminal device is configured to apply the first transmission configuration indication state (TCI state) or the second transmission configuration indication state (TCI state) to send the PUSCH: the terminal device is configured with the first parameter (precodingAndNumberOfLayers) and / or the second parameter (srs-ResourceIndicator), or, the terminal device is configured with the first parameter (precodingAndNumberOfLayers) and the third parameter (precodingAndNumberOfLayers2), and / or, the terminal device is configured with the second parameter (srs-ResourceIndicator) and the fourth parameter (srs-ResourceIndicator2).

[0107] For example, when the value of the field "applyIndicatedTCIState" in the aforementioned first configuration information is configured as "the first" or "the second", the terminal device is configured with the first parameter (precodingAndNumberOfLayers) and / or the second parameter (srs-ResourceIndicator).

[0108] For example, for codebook-based PUSCH transmission, the terminal device is configured with a first parameter (precodingAndNumberOfLayers) and a second parameter (srs-ResourceIndicator); for non-codebook-based PUSCH transmission, the terminal device is configured with a second parameter (srs-ResourceIndicator).

[0109] In some embodiments, when the terminal device is configured to apply the first TCI state to send PUSCH, the terminal device sends PUSCH according to the first TPMI and / or the first SRI; when the terminal device is configured to apply the second TCI state to send PUSCH, the terminal device sends PUSCH according to the second TPMI and / or the second SRI.

[0110] For example, the terminal device is configured with a first parameter (precodingAndNumberOfLayers) and a third parameter (precodingAndNumberOfLayers2), and / or the terminal device is configured with a second parameter (srs-ResourceIndicator) and a fourth parameter (srs-ResourceIndicator2); for example, when the value of the field "applyIndicatedTCIState" is configured as "the first", the terminal device uses the first parameter (precodingAndNumberOfLayers) and / or the second parameter (srs-ResourceIndicator) to send PUSCH, and when the value of the field "applyIndicatedTCIState" is configured as "the second", the terminal device uses the third parameter (precodingAndNumberOfLayers2) and / or the fourth parameter (srs-ResourceIndicator2) to send PUSCH.

[0111] Table 2 schematically illustrates the first parameter and the second parameter.

[0112] For example, as shown in Table 2, the first configuration information "ConfiguredGrantConfig" includes a parameter "rrc-ConfiguredUplinkGrant", and the parameter "rrc-ConfiguredUplinkGrant" includes a first parameter (precodingAndNumberOfLayers) and a second parameter (srs-ResourceIndicator).

[0113] For example, as shown in Table 2, when the value of the field "applyIndicatedTCIState" in the aforementioned first configuration information is configured as "the first" or "the second", the terminal device uses the first parameter (precodingAndNumberOfLayers) and / or the second parameter (srs-ResourceIndicator) in Table 2 to send PUSCH.

[0114] For example, the first parameter (precodingAndNumberOfLayers) is an integer ranging from 0 to 63, the second parameter (srs-ResourceIndicator) is an integer ranging from 0 to 15, etc. For the specific content of the first parameter (precodingAndNumberOfLayers) and the second parameter (srs-ResourceIndicator), please refer to the prior art, and this application does not limit this.

[0115] Table 2

[0116] Table 3 provides another schematic description of the first parameter and the second parameter.

[0117] For example, as shown in Table 3, the first configuration information "ConfiguredGrantConfig" includes the parameter "rrc-ConfiguredUplinkGrant", and the parameter "rrc-ConfiguredUplinkGrant" includes the first parameter (precodingAndNumberOfLayers), the second parameter (srs-ResourceIndicator), the third parameter (precodingAndNumberOfLayers2), and the fourth parameter (srs-ResourceIndicator2).

[0118] For example, when the value of the field "applyIndicatedTCIState" in the aforementioned first configuration information is configured as "the first" or "the second", the terminal device is configured with the first parameter (precodingAndNumberOfLayers) and the third parameter (precodingAndNumberOfLayers2), and / or, the terminal device is configured with the second parameter (srs-ResourceIndicator) and the fourth parameter (srs-ResourceIndicator2).

[0119] For example, for codebook based PUSCH transmission, the terminal device is configured with the first parameter (precodingAndNumberOfLayers) and the third parameter (precodingAndNumberOfLayers2), and the terminal device is configured with the second parameter (srs-ResourceIndicator) and the fourth parameter (srs-ResourceIndicator2); for non-codebook based PUSCH transmission, the terminal device is configured with the second parameter (srs-ResourceIndicator) and the fourth parameter (srs-ResourceIndicator2).

[0120] For example, as shown in Table 3, when the value of the field "applyIndicatedTCIState" in the aforementioned first configuration information is configured as "the first" or "the second", the terminal device only uses the first parameter (precodingAndNumberOfLayers) and / or the second parameter (srs-ResourceIndicator) to send PUSCH, and the terminal device ignores the third parameter (precodingAndNumberOfLayers2) and the fourth parameter (srs-ResourceIndicator2); or, when the value of the field "applyIndicatedTCIState" in the aforementioned first configuration information is configured as "the first" or "the second", the terminal device only uses the third parameter (precodingAndNumberOfLayers2) and / or the fourth parameter (srs-ResourceIndicator2) to send PUSCH, and the terminal device ignores the first parameter (precodingAndNumberOfLayers) and the second parameter (srs-ResourceIndicator).

[0121] For example, the first parameter (precodingAndNumberOfLayers) and the third parameter (precodingAndNumberOfLayers2) are integers ranging from 0 to 63; the second parameter (srs-ResourceIndicator) and the fourth parameter (srs-ResourceIndicator2) are integers ranging from 0 to 15, etc. For the specific contents of the first parameter (precodingAndNumberOfLayers), the second parameter (srs-ResourceIndicator), the third parameter (precodingAndNumberOfLayers2) and the fourth parameter (srs-ResourceIndicator2), please refer to the prior art, and this application does not limit this.

[0122] Table 3

[0123] Therefore, according to the first configuration information shown in Tables 1 to 3, the first transmission precoding matrix indication information (TPMI) and / or the first SRS resource indication information (SRI) can be configured. Therefore, when the terminal device is configured to apply the first transmission configuration indication state (TCI state) or the second transmission configuration indication state (TCI state) to send PUSCH, the terminal device can accurately send the PUSCH according to the first transmission precoding matrix indication information (TPMI) and / or the first SRS resource indication information (SRI).

[0124] In some embodiments, the terminal device is also configured with two SRS resource sets (SRS resource sets); wherein, when the terminal device is configured to apply the first transmission configuration indication state (TCI state) to send the PUSCH: the first transmission precoding matrix indication information (TPMI) and / or the first SRS resource indication information (SRI) are associated with the first SRS resource set (SRS resource set); when the terminal device is configured to apply the second transmission configuration indication state (TCI state) to send the PUSCH: the first transmission precoding matrix indication information (TPMI) and / or the first SRS resource indication information (SRI) are associated with the second SRS resource set (SRS resource set).

[0125] In some embodiments, the terminal device further receives third configuration information. For example, the third configuration information is the parameter "SRS-Config", such as the parameter "srs-ResourceSetToAddModList" in the parameter "SRS-Config", or the parameter "srs-ResourceSetToAddModListDCI-0-2" configuring the two SRS resource sets.

[0126] For example, the terminal device is configured with two SRS resource sets. When the value of the field "applyIndicatedTCIState" in the aforementioned first configuration information is configured as "the first", the first transmission precoding matrix indication information (TPMI) and / or the first parameter (precodingAndNumberOfLayers) and / or the second parameter (srs-ResourceIndicator) of the first SRS resource indication information (SRI) are configured to be associated with the first SRS resource set of the two SRS resource sets. When the value of the field "applyIndicatedTCIState" in the aforementioned first configuration information is configured as "the second", the first transmission precoding matrix indication information (TPMI) and / or the first parameter (precodingAndNumberOfLayers) and / or the second parameter (srs-ResourceIndicator) of the first SRS resource indication information (SRI) are configured to be associated with the second SRS resource set of the two SRS resource sets.

[0127] For example, the first parameter (precodingAndNumberOfLayers) and / or the second parameter (srs-ResourceIndicator) are associated with one of the aforementioned SRS resource sets, indicating that the second parameter (srs-ResourceIndicator) indicates one or more SRS resources in the certain SRS resource set, and / or, the PUSCH sent by the terminal device using the first parameter (precodingAndNumberOfLayers) and the SRS resource indicated by the second parameter (srs-ResourceIndicator) sent by the terminal device use the same antenna port (PUSCH antenna port).

[0128] Thus, the terminal device can determine the SRS resource set (SRS resource set) and the corresponding SRS resources corresponding to sending the PUSCH, so that the PUSCH can be sent accurately.

[0129] In some embodiments, when the terminal device is configured to apply a first transmission configuration indication state (TCI state) and a second transmission configuration indication state (TCI state) to send the PUSCH, the PUSCH is sent according to the first transmission precoding matrix indication information (TPMI) and the second transmission precoding matrix indication information (TPMI), and / or according to the first SRS resource indication information (SRI) and the second SRS resource indication information (SRI).

[0130] For example, as shown in Table 1, when the value in the field "applyIndicatedTCIState" is configured as "both", it indicates that the first TCI state and the second TCI state are applied to send a PUSCH configured with grant type 1.

[0131] For example, for codebook based PUSCH transmission, the terminal device sends PUSCH according to the "first TPMI, second TPMI, first SRI and second SRI"; for non-codebook based PUSCH transmission, the terminal device sends PUSCH according to the first SRI and the second SRI.

[0132] In some embodiments, when the terminal device is configured to apply the first transmission configuration indication state (TCI state) and the second transmission configuration indication state (TCI state) to send the PUSCH: the first transmission precoding matrix indication information (TPMI) is configured by a first parameter (precodingAndNumberOfLayers), and the second transmission precoding matrix indication information (TPMI) is configured by a third parameter (precodingAndNumberOfLayers2); and / or, the first SRS resource indication information (SRI) is configured by a second parameter (srs-ResourceIndicator), and the second SRS resource indication information (SRI) is configured by a fourth parameter (srs-ResourceIndicator2).

[0133] For example, as shown in Table 1, when the value in the field "applyIndicatedTCIState" is configured as "both", the first TPMI is configured through the RRC parameter: the first parameter (precodingAndNumberOfLayers), the first SRI is configured through the RRC parameter: the second parameter (srs-ResourceIndicator), the second TPMI is configured through the RRC parameter: the third parameter (precodingAndNumberOfLayers2), and the second SRI is configured through the RRC parameter: the fourth parameter (srs-ResourceIndicator2).

[0134] In some embodiments, when the terminal device is configured to apply the first transmission configuration indication state (TCI state) and the second transmission configuration indication state (TCI state) to send the PUSCH: the terminal device is configured with the first parameter (precodingAndNumberOfLayers) and the third parameter (precodingAndNumberOfLayers2), and / or, the terminal device is configured with the second parameter (srs-ResourceIndicator) and the fourth parameter (srs-ResourceIndicator2).

[0135] For example, as shown in Table 1, when the value in the field "applyIndicatedTCIState" is configured as "both", for codebook based PUSCH transmission, the terminal device is configured with the first parameter (precodingAndNumberOfLayers) and the third parameter (precodingAndNumberOfLayers2), and the terminal device is configured with the second parameter (srs-ResourceIndicator) and the fourth parameter (srs-ResourceIndicator2); for non-codebook based PUSCH transmission, the terminal device is configured with the second parameter (srs-ResourceIndicator) and the fourth parameter (srs-ResourceIndicator2).

[0136] For example, Table 1 and Table 3 are still used to illustrate this. When the value in the field "applyIndicatedTCIState" in Table 1 is configured as "both", the terminal device uses the first parameter (precodingAndNumberOfLayers) and the third parameter (precodingAndNumberOfLayers2) shown in Table 3, and / or, the second parameter (srs-ResourceIndicator) and the fourth parameter (srs-ResourceIndicator2) to send the PUSCH.

[0137] Therefore, according to the first configuration information shown in Tables 1 to 3, the first transmission precoding matrix indication information (TPMI) and / or the first SRS resource indication information (SRI) can be configured. Therefore, when the terminal device is configured to apply the first transmission configuration indication state (TCI state) and the second transmission configuration indication state (TCI state) to send PUSCH, the terminal device can accurately send the PUSCH according to the first transmission precoding matrix indication information (TPMI) and the second transmission precoding matrix indication information (TPMI), and / or the first SRS resource indication information (SRI) and the second SRS resource indication information (SRI).

[0138] In some embodiments, the terminal device is also configured with two SRS resource sets (SRS resource sets); wherein, when the terminal device is configured to apply a first transmission configuration indication state (TCI state) and a second transmission configuration indication state (TCI state) to send the PUSCH: the first transmission precoding matrix indication information (TPMI) and / or the first SRS resource indication information (SRI) is associated with the first SRS resource set of the two SRS resource sets (SRS resource sets); and the second transmission precoding matrix indication information (TPMI) and / or the second SRS resource indication information (SRI) is associated with the second SRS resource set of the two SRS resource sets (SRS resource sets).

[0139] For example, the two SRS resource sets are still configured through the parameter "srs-ResourceSetToAddModList" in the aforementioned third configuration information (parameter "SRS-Config"), or the parameter "srs-ResourceSetToAddModListDCI-0-2".

[0140] For example, when the terminal device is configured with two SRS resource sets and the value in the field "applyIndicatedTCIState" is configured as "both", the first parameter (precodingAndNumberOfLayers) and / or the second parameter (srs-ResourceIndicator) of the first transmission precoding matrix indication information (TPMI) and / or the first SRS resource indication information (SRI) are configured to be associated with the first SRS resource set of the two SRS resource sets, and the third parameter (precodingAndNumberOfLayers2) and / or the fourth parameter (srs-ResourceIndicator2) of the second transmission precoding matrix indication information (TPMI) and / or the second SRS resource indication information (SRI) are configured to be associated with the second SRS resource set of the two SRS resource sets.

[0141] Thus, the terminal device can determine the SRS resource set (SRS resource set) and the corresponding SRS resources corresponding to sending the PUSCH, so that the PUSCH can be sent accurately.

[0142] In some embodiments, the terminal device is further configured with a multi-panel scheme; or, the terminal device is not configured with a multi-panel scheme; wherein the multi-panel scheme indicates the use of a spatial division multiplexing (SDM) scheme or a single frequency network (SFN) scheme.

[0143] For example, the terminal device uses a multi-panel scheme (multipanelScheme) to indicate the use of a spatial division multiplexing (SDM) scheme or a single frequency network (SFN) scheme to send PUSCH, corresponding to the use of the STxMP SDM scheme and the STxMP SFN scheme shown in Figures 3 and 4 to send PUSCH. For the specific transmission process of the PUSCH, please refer to the previous part of the specification and will not be repeated here.

[0144] In some implementations, the terminal device further receives fourth configuration information. For example, the fourth configuration information is an RRC parameter "multipanelScheme", which can be configured as an SDM scheme (SDMScheme) or an SFN scheme (SFNScheme).

[0145] Table 4 provides a schematic illustration of the fourth configuration information. As shown in Table 4, the RRC parameter "multipanelScheme" corresponds to the fourth configuration information of the present application, and the value of "multipanelScheme" can be "SDMScheme" or "SFNScheme".

[0146] Table 4

[0147] In some implementations, the terminal device may not be configured with the RRC parameter multipanelScheme.

[0148] In some embodiments, when the terminal device is configured to apply the first transmission configuration indication state (TCI state) or the second transmission configuration indication state (TCI state) to send the PUSCH, the terminal device does not expect to be configured with a multi-panel scheme.

[0149] For example, the statement "the terminal device does not expect to be configured with a multi-panel scheme (multipanel Scheme)" can be replaced with "the terminal device is not configured or is not scheduled for a multi-panel scheme (multipanel Scheme)", and can also be replaced with "the terminal device does not receive the fourth configuration information", and can also be replaced with "the network device does not configure or schedule a multi-panel scheme (multipanel Scheme)", and can also be replaced with "the network device does not send the fourth configuration information", etc. This application does not impose any restrictions on this.

[0150] In some implementations, the terminal device is configured with a multi-panel scheme (multipanelScheme) by the second configuration information (PUSCH-Config), or the terminal device is configured with a multi-panel scheme (multipanelScheme) by the first configuration information (ConfiguredGrantConfig).

[0151] For example, a multi-panel scheme (multipanelScheme) is configured in the first configuration information "ConfiguredGrantConfig", or a multi-panel scheme (multipanelScheme) is configured in the second configuration information "PUSCH-Config"; for the specific content of the first configuration information "ConfiguredGrantConfig", please refer to the aforementioned part of the specification and the prior art, and this application does not limit this, and for the specific content of the second configuration information "PUSCH-Config", please refer to the prior art, and this application does not limit this.

[0152] In some embodiments, when the terminal device is configured to apply the first transmission configuration indication state (TCI state) or the second transmission configuration indication state (TCI state) to send the PUSCH: the terminal device is configured with a multi-panel scheme; or, when the terminal device is not configured with a multi-panel scheme, the PUSCH is sent according to a single transmission reception point (sTRP) scheme; and / or, when the terminal device is configured to apply the first transmission configuration indication state (TCI state) and the second transmission configuration indication state (TCI state) state) when the PUSCH is sent: when the terminal device is configured with a multi-panel scheme (multipanelScheme) and the multi-panel scheme (multipanelScheme) indicates the use of the spatial division multiplexing (SDM) scheme, the PUSCH is sent according to the spatial division multiplexing (SDM) scheme; when the terminal device is configured with a multi-panel scheme (multipanelScheme) and the multi-panel scheme (multipanelScheme) indicates the use of the single frequency network (SFN) scheme, the PUSCH is sent according to the single frequency network (SFN) scheme; when the terminal device is not configured with a multi-panel scheme (multipanelScheme), the PUSCH is sent according to the time division multiplexing (TDM) scheme.

[0153] For example, when the value in the field "applyIndicatedTCIState" is configured as "the first" or "the second", regardless of whether the terminal device is configured with "multipanelScheme", the terminal device uses the sTRP scheme to send PUSCH. For example, the terminal device uses the sTRP scheme shown in Figure 5 to send PUSCH, which is not repeated here.

[0154] For example, using the sTRP solution includes at least one of the following: using an SRS resource set; using a TPMI and / or an SRI. An SRS resource set can be the first SRS resource set or the second SRS resource set, a TPMI can be the first TPMI or the second TPMI, and an SRI can be the first SRI or the second SRI.

[0155] For example, in the case where the value in the field "applyIndicatedTCIState" is configured as "both", if the terminal device is configured with "multipanelScheme" and "multipanelScheme" is configured as "SDMScheme", the terminal device uses the SDM scheme to send PUSCH; and if the terminal device is configured with "multipanelScheme" and "multipanelScheme" is configured as "SFNScheme", the terminal device uses the SFN scheme to send PUSCH; if the terminal device is not configured with "multipanelScheme", the terminal device uses the TDM scheme to send PUSCH.

[0156] For example, using the SDM scheme includes at least one of the following: using two SRS resource sets; using two TPMIs and / or two SRIs; applying a first TPMI and / or a first SRI to a portion of a transmission layer of a PUSCH at one transmission opportunity, and applying a second TPMI and / or a second SRI to another portion of the transmission layer of the PUSCH at the same transmission opportunity. For example, the terminal device transmits a PUSCH using the SDM scheme shown in FIG3 , which is not repeated here.

[0157] For example, using the SFN scheme includes at least one of the following: using two SRS resource sets; using two TPMIs and / or two SRIs; applying a first TPMI and / or a first SRI to all transmission layers of a PUSCH at a transmission opportunity, and applying a second TPMI and / or a second SRI to all transmission layers of the PUSCH at the transmission opportunity. For example, a terminal device transmits a PUSCH using the SFN scheme shown in FIG4 , and a repeated description thereof is not provided here.

[0158] For example, using a TDM scheme includes at least one of the following: using two SRS resource sets; using two TPMIs and / or two SRIs; applying a first TPMI and / or a first SRI to all transmission layers of a PUSCH at a transmission timing associated with a first SRS resource set, and applying a second TPMI and / or a second SRI to all transmission layers of a PUSCH at a transmission timing associated with a second SRS resource set. For example, a terminal device transmits a PUSCH using the TDM scheme shown in FIG6 , which is not repeated here.

[0159] As a result, the device behavior for configured grant Type 1 PUSCH transmissions is accurately defined for each configuration combination. This avoids ambiguity between terminal devices and network equipment regarding the transmission parameters actually applied to configured grant Type 1 PUSCH, thereby preventing PUSCH transmission failures and enabling reliable uplink data transmission.

[0160] The following details how a terminal device determines the association between a PT-RS port and a DM-RS port, and how a terminal device determines the number of PT-RS ports actually used.

[0161] Regarding "How does the terminal device determine the association relationship between the PT-RS port and the DM-RS port":

[0162] In some embodiments, when the terminal device is configured to apply a first transmission configuration indication state (TCI state) or a second transmission configuration indication state (TCI state) to send the PUSCH, and when the terminal device is configured with a multipanel scheme (multipanelScheme) and the multipanel scheme (multipanelScheme) indicates the use of the spatial division multiplexing (SDM) scheme, the association relationship between the PT-RS port and the DM-RS port includes: PT-RS port 0 is associated with the first scheduled DM-RS port, or, PT-RS port 0 is associated with the first DM-RS port sharing the PT-RS port 0, and PT-RS port 1 is associated with the first DM-RS port sharing the PT-RS port 1.

[0163] Therefore, when a terminal device is configured to apply the first or second TCI state and transmit PUSCH using the SDM scheme, the association between the PT-RS port and the DM-RS port can be determined according to predefined rules. This avoids ambiguity between the terminal device and network equipment in understanding the transmission parameters actually applied to the configured grant Type 1 PUSCH, thereby preventing PUSCH transmission failures and enabling reliable transmission of uplink data.

[0164] For example, when the value in the field "applyIndicatedTCIState" is configured as "the first" or "the second" and the terminal device is configured with "multipanelScheme" and "multipanelScheme" is configured as "SDMScheme", the association relationship between the PT-RS port and the DM-RS port is determined in the following first manner: PT-RS port 0 is associated with the first scheduled DM-RS port.

[0165] For example, "the first scheduled DM-RS port" refers to the first DM-RS port among the DM-RS ports used to configure the PUSCH of grant type 1. For configuring grant type 1, the parameters required for uplink transmission (including the DM-RS port) are configured in a semi-static manner. Among the one or more configured DM-RS ports, the first DM-RS port is associated with PT-RS port 0. For example, the expression "the first scheduled DM-RS port" can also be replaced with "the first DM-RS port", etc., and this application is not limited to this.

[0166] For example, when the value in the field "applyIndicatedTCIState" is configured as "the first" or "the second" and the terminal device is configured with "multipanelScheme" and "multipanelScheme" is configured as "SDMScheme", the association relationship between the PT-RS port and the DM-RS port is determined in the following second manner: PT-RS port 0 is associated with the first DM-RS port sharing PT-RS port 0, and PT-RS port 1 is associated with the first DM-RS port sharing PT-RS port 1.

[0167] For example, the DM-RS ports that share a PT-RS port are determined according to the following second approach: PUSCH antenna ports 1000 and 1002 share PT-RS port 0, and PUSCH antenna ports 1001 and 1003 share PT-RS port 1; one or more DM-RS ports transmitted via PUSCH antenna ports 1000 and 1002 share PT-RS port 0, and one or more DM-RS ports transmitted via PUSCH antenna ports 1001 and 1003 share PT-RS port 1. For example, regarding how to determine which DM-RS ports are transmitted via PUSCH antenna ports 1000 and 1002, and which DM-RS ports are transmitted via PUSCH antenna ports 1001 and 1003, reference can be made to the prior art, and this application does not impose any limitation thereto. For example, the term "DM-RS port" described above can also be replaced with "transport layer," etc., and this application does not impose any limitation thereto.

[0168] In some embodiments, the association relationship between the PT-RS port and the DM-RS port also includes: when the terminal device is configured as 1 PT-RS port by the fifth parameter, the PT-RS port 0 is associated with the first scheduled DM-RS port; and / or, when the terminal device is configured as 2 PT-RS ports by the fifth parameter, the PT-RS port 0 is associated with the first DM-RS port sharing the PT-RS port 0, and the PT-RS port 1 is associated with the first DM-RS port sharing the PT-RS port 1.

[0169] For example, the fifth parameter is "maxNrofPorts", which is configured in the RRC parameter "PTRS-UplinkConfig" and indicates the maximum number of PT-RS ports. For example, the RRC parameter "PTRS-UplinkConfig" also includes a sixth parameter "maxNrofPortsforSDM", which indicates the maximum number of PT-RS ports applied to the SDM scheme, wherein the fifth parameter "maxNrofPorts" and the sixth parameter "maxNrofPortsforSDM" are different parameters.

[0170] For example, when the terminal device is configured with "maxNrofPorts" as 1 PT-RS port, when the value in the field "applyIndicatedTCIState" is configured as "the first" or "the second" and the terminal device is configured with "multipanelScheme" and "multipanelScheme" is configured as "SDMScheme", the association relationship between the PT-RS port and the DM-RS port is determined according to the first method described above.

[0171] For example, when the terminal device is configured with 2 PT-RS ports by "maxNrofPorts", when the value in the field "applyIndicatedTCIState" is configured as "the first" or "the second" and the terminal device is configured with "multipanelScheme" and "multipanelScheme" is configured as "SDMScheme", the association relationship between the PT-RS port and the DM-RS port is determined according to the second method described above.

[0172] Therefore, when the terminal device is configured to apply the first TCI state or the second TCI state and use the SDM scheme to send PUSCH, the association relationship between the PT-RS port and the DM-RS port can be determined according to predefined rules.

[0173] In some embodiments, when the terminal device is configured to apply a first transmission configuration indication state (TCI state) and a second transmission configuration indication state (TCI state) to send the PUSCH, and when the terminal device is configured with a multipanel scheme (multipanelScheme) and the multipanel scheme (multipanelScheme) indicates the use of the spatial division multiplexing (SDM) scheme, the association relationship between the PT-RS port and the DM-RS port includes: PT-RS port 0 is associated with the first scheduled DM-RS port, or PT-RS port 0 is associated with the first scheduled DM-RS port corresponding to the first transmission precoding matrix indication information (TPMI) and / or the first SRS resource indication information (SRI), and PT-RS port 1 is associated with the first scheduled DM-RS port corresponding to the second transmission precoding matrix indication information (TPMI) and / or the second SRS resource indication information (SRI).

[0174] For example, when the value in the field "applyIndicatedTCIState" is configured as "both" and the terminal device is configured with "multipanelScheme" and "multipanelScheme" is configured as "SDMScheme", the association relationship between the PT-RS port and the DM-RS port is determined according to the following third method: PT-RS port 0 is associated with the first scheduled DM-RS port.

[0175] For example, when the value in the field "applyIndicatedTCIState" is configured as "both" and the terminal device is configured with "multipanelScheme" and "multipanelScheme" is configured as "SDMScheme", the association relationship between the PT-RS port and the DM-RS port is determined according to the following fourth method: PT-RS port 0 is associated with the first scheduled DM-RS port corresponding to the first TPMI and / or the first SRI, and PT-RS port 1 is associated with the first scheduled DM-RS port corresponding to the second TPMI and / or the second SRI. For how to determine which DM-RS ports correspond to the first TPMI and / or the first SRI, and which DM-RS ports correspond to the second TPMI and / or the second SRI, please refer to the prior art in the SDM scheme, and this application does not limit this. For example, the above-mentioned expression of "the first scheduled DM-RS port" can also be replaced with "the first DM-RS port", etc., and this application does not limit this.

[0176] For example, when the value in the field "applyIndicatedTCIState" is configured as "both" and the terminal device is configured with "multipanelScheme" and "multipanelScheme" is configured as "SDMScheme", the association relationship between the PT-RS port and the DM-RS port is determined according to the third method or the fourth method mentioned above; in cases other than the above two cases, the association relationship between the PT-RS port and the DM-RS port is determined according to the first method or the second method described above.

[0177] In some embodiments, the association relationship between the PT-RS port and the DM-RS port also includes: when the terminal device is configured as 1 PT-RS port by the sixth parameter, the PT-RS port 0 is associated with the first scheduled DM-RS port; and / or, when the terminal device is configured as 2 PT-RS ports by the sixth parameter, the PT-RS port 0 is associated with the first scheduled DM-RS port corresponding to the first transmission precoding matrix indication information (TPMI) and / or the first SRS resource indication information (SRI), and the PT-RS port 1 is associated with the first scheduled DM-RS port corresponding to the second transmission precoding matrix indication information (TPMI) and / or the second SRS resource indication information (SRI).

[0178] For example, the sixth parameter is the aforementioned parameter "maxNrofPortsforSDM".

[0179] For example, when the terminal device is configured with "maxNrofPortsforSDM" as 1 PT-RS port, when the value in the field "applyIndicatedTCIState" is configured as "both" and the terminal device is configured with "multipanelScheme" and "multipanelScheme" is configured as "SDMScheme", the association relationship between the PT-RS port and the DM-RS port is determined according to the third method described above.

[0180] For example, when the terminal device is configured with 2 PT-RS ports by "maxNrofPortsforSDM", the value in the field "applyIndicatedTCIState" is configured as "both" and the terminal device is configured with "multipanelScheme" and "multipanelScheme" is configured as "SDMScheme", the association relationship between the PT-RS port and the DM-RS port is determined according to the fourth method described above.

[0181] Therefore, when the terminal device is configured to apply the first TCI state and the second TCI state and use the SDM scheme to send PUSCH, the association relationship between the PT-RS port and the DM-RS port can be determined according to predefined rules.

[0182] Regarding "How does the terminal device determine the number of PT-RS ports actually used?"

[0183] In some embodiments, when the terminal device is configured to apply the first transmission configuration indication state (TCI state) or the second transmission configuration indication state (TCI state) to send the PUSCH, the number of PT-RS ports actually applied is determined based on the first transmission precoding matrix indication information (TPMI) and / or the first SRS resource indication information (SRI).

[0184] This allows the determination of the number of PT-RS ports actually used when a terminal device is configured to transmit PUSCH using either the first or second TCI state. This prevents ambiguity between the terminal device and network equipment regarding the transmission parameters actually used for the configured grant Type 1 PUSCH, thereby preventing PUSCH transmission failures and enabling reliable uplink data transmission.

[0185] For example, the expression "the number of PT-RS ports actually used" can be replaced with "the actual number of PT-RS ports" and the like, and this application does not impose any limitation on this.

[0186] For example, when the value in the field "applyIndicatedTCIState" is configured as "the first" or "the second", the actual number of PT-RS ports applied is determined according to the first parameter (precodingAndNumberOfLayers) and / or the second parameter (srs-ResourceIndicator).

[0187] For example, when the value in the field "applyIndicatedTCIState" is configured as "the first" or "the second" and the terminal device is configured with "multipanelScheme" and "multipanelScheme" is configured as "SDMScheme", the actual number of PT-RS ports applied is determined according to the first parameter (precodingAndNumberOfLayers) and / or the second parameter (srs-ResourceIndicator).

[0188] In some embodiments, when the PUSCH is a non-codebook based PUSCH, the number of PT-RS ports actually used is determined according to the first SRS resource indication information (SRI), and / or, when the PUSCH is a partially coherent, codebook based PUSCH, the number of PT-RS ports actually used is determined according to the first transmission precoding matrix indication information (TPMI), and / or, when the PUSCH is a non-coherent, codebook based PUSCH, the number of PT-RS ports actually used is determined according to the first transmission precoding matrix indication information (TPMI).

[0189] For example, when the value in the "applyIndicatedTCIState" field is configured as "the first" or "the second": for non-codebook-based PUSCH, the actual number of PT-RS ports used is determined based on the second parameter (srs-ResourceIndicator); for partially coherent, codebook-based PUSCH, the actual number of PT-RS ports used is determined based on the first parameter (precodingAndNumberOfLayers); for non-coherent, codebook-based PUSCH, the actual number of PT-RS ports used is determined based on precodingAndNumberOfLayers. For how to determine the actual number of PT-RS ports based on the first parameter (precodingAndNumberOfLayers) and / or the second parameter (srs-ResourceIndicator), reference may be made to the prior art, and this application does not impose any restrictions thereon.

[0190] The above describes how a terminal device determines the association between a PT-RS port and a DM-RS port and determines the number of PT-RS ports for actual application. Based on the above, several examples are given below.

[0191] For example, assuming that the "multipanelScheme" is configured as SDMScheme, the value in "applyIndicatedTCIState" is configured as "the second", and the fifth parameter (maxNrofPorts) is configured as 2:

[0192] For PUSCH with codebook-based configuration grant type 1, when "applyIndicatedTCIState" is configured as "the second", the terminal device determines the precoding matrix according to the first parameter (precodingAndNumberOfLayers). Assume that the determined precoding matrix is The terminal device determines that the DM-RS ports to be used are 0 to 3 according to the first configuration information (ConfiguredGrantConfig); when the fifth parameter (maxNrofPorts) is configured to 2, the association relationship between the PT-RS port and the DM-RS port is: PT-RS port 0 is associated with the first DM-RS port shared by PT-RS port 0, and PT-RS port 1 is associated with the first DM-RS port shared by PT-RS port 1; DM-RS ports 0 and 1 are sent through PUSCH antenna ports 1000 and 1002, and therefore share PT-RS port 0; DM-RS ports 2 and 3 are sent through PUSCH antenna ports 1001 and 1003, and therefore share PT-RS port 1; according to the first parameter (precodingAndNumberOfLayers), it can be seen that the transmitted DM-RS port is associated with two PT-RS ports, so the actual number of PT-RS ports is 2; according to the association relationship between the PT-RS port and the DM-RS port, PT-RS port 0 is associated with DM-RS port 0, and PT-RS port 1 is associated with DM-RS port 2.

[0193] For example, assuming that the "multipanelScheme" is configured as SDMScheme, the value in "applyIndicatedTCIState" is configured as "the second", and the fifth parameter (maxNrofPorts) is configured as 2:

[0194] For PUSCH with codebook-based configuration grant type 1, when "applyIndicatedTCIState" is configured as "the second", the terminal device determines the precoding matrix according to the first parameter (precodingAndNumberOfLayers). Assume that the determined precoding matrix is The terminal device determines that the DM-RS ports to be used are 0 and 1 according to the first configuration information (ConfiguredGrantConfig); when the fifth parameter (maxNrofPorts) is configured to 2, the association relationship between the PT-RS port and the DM-RS port is: PT-RS port 0 is associated with the first DM-RS port shared by PT-RS port 0, and PT-RS port 1 is associated with the first DM-RS port shared by PT-RS port 1; DM-RS ports 0 and 1 are sent through PUSCH antenna ports 1001 and 1003, and therefore share PT-RS port 1; according to the first parameter (precodingAndNumberOfLayers), it can be seen that the transmitted DM-RS port is associated with one PT-RS port, so the number of PT-RS ports actually used is 1 (although the fifth parameter (maxNrofPorts) is configured to 2); according to the association relationship between the PT-RS port and the DM-RS port, it can be seen that PT-RS port 1 is associated with DM-RS port 0.

[0195] For example, assuming that the "multipanelScheme" is configured as SDMScheme, the value in "applyIndicatedTCIState" is configured as "the second", and the fifth parameter (maxNrofPorts) is configured as 1:

[0196] For PUSCH with codebook-based configuration grant type 1, when "applyIndicatedTCIState" is configured as "the second", the terminal device determines the precoding matrix according to the first parameter (precodingAndNumberOfLayers). Assume that the determined precoding matrix is The terminal device determines that the DM-RS port to be used is 0 according to the first configuration information (ConfiguredGrantConfig); when the fifth parameter (maxNrofPorts) is configured to 1, the association relationship between the PT-RS port and the DM-RS port is: PT-RS port 0 is associated with the first scheduled DM-RS port; when the fifth parameter (maxNrofPorts) is configured to 1, the number of PT-RS ports actually used is 1; according to the association relationship between the PT-RS port and the DM-RS port, it can be seen that PT-RS port 0 is associated with DM-RS port 0.

[0197] For example, when "multipanelScheme" is configured as SDMScheme and the value in the field "applyIndicatedTCIState" is configured as "both", the association relationship between the PT-RS port and the DM-RS port is determined according to the third or fourth method described above; when "multipanelScheme" is configured as SDMScheme and the value in "applyIndicatedTCIState" is configured as "the first" or "the second", the association relationship between the PT-RS port and the DM-RS port is determined according to the first or second method described above; when "multipanelScheme" is configured as SFNScheme, the association relationship between the PT-RS port and the DM-RS port is determined according to the first or second method described above; when the terminal device is not configured with "multipanelScheme", the association relationship between the PT-RS port and the DM-RS port is determined according to the first or second method described above. For example, the association relationship between the PT-RS port and the DM-RS port is determined according to the first method, which can also be referred to as the association relationship between the PT-RS port and the DM-RS port. The "value" in Table 5 below (corresponding to "Table 7.3.1.1.2-25" in the standard) is determined by a row corresponding to "0". The association relationship between the PT-RS port and the DM-RS port is determined according to the second method, which can also be referred to as the association relationship between the PT-RS port and the DM-RS port. The "value of MSB" and "value of" in Table 6 below (corresponding to "Table 7.3.1.1.2-26" in the standard) are determined. The association relationship between the PT-RS port and the DM-RS port is determined according to the third method, which can also be referred to as the association relationship between the PT-RS port and the DM-RS port is determined by the row corresponding to the "value" value of "0" in the following Table 5 (corresponding to "Table 7.3.1.1.2-25" in the standard). The association relationship between the PT-RS port and the DM-RS port is determined according to the fourth method, which can also be referred to as the association relationship between the PT-RS port and the DM-RS port is determined by the row corresponding to the "value of MSB" and "value of LSB" values ​​​​of "00" in the following Table 7 (corresponding to "Table 7.3.1.1.2-25a" in the standard).

[0198] For example, the English description and modifications in the corresponding standard are as follows:

[0199] “For codebook or non-codebook based UL transmission,the association between UL PT-RS port(s)and DM-RS port(s)is signalled by PTRS-DMRS association field(s)in DCI format 0_1 and DCI format 0_2.Except for the case when the higher layer parameter multipanelScheme is configured, for a PUSCH corresponding to a configured grant Type 1 transmission,the UE may assume the association between UL PT-RS port(s)and DM-RS port(s)defined by value 0 in Table 7.3.1.1.2-25,value"00"in Table 7.3.1.1.1.2-26 described in Clause 7.3.1 of[5,TS38.212].[For a PUSCH corresponding to a configured grant Type 1 transmission and when the higher layer parameter multipanelScheme is set to‘SFNscheme’,the UE may assume the association between UL PT-RS port(s)and DM-RS port(s)defined by value 0 in Table 7.3.1.1.2-25or value"00"in Table 7.3.1.1.1.2-26 described in Clause 7.3.1 of[5,TS38.212].For a PUSCH corresponding to a configured grant Type 1 transmission When the higher layer parameter multipanelScheme is set to ‘sdmscheme’ and the higher layer parameter applyIndicatedTCIState in ConfiguredGrantConfig is set to ‘both’, the UE may assume the association between UL PT-RS port(s) and DM-RS port(s) defined by value 0 in Table 7.3.1.1.2-25 or value "00" in Table 7.3.1.1.1.2-25a described in Clause 7.3.1 of [5,TS38.212]. For a PUSCH corresponding to a configured grant Type 1 transmission, when the higher layer parameter multipanelScheme is set to ‘sdmscheme’ and the higher layer parameter applyIndicatedTCIState in ConfiguredGrantConfig is set to ‘the first’ or ‘the second’, the UE may assume the association between UL PT-RS port(s) and DM-RS port(s) defined by value 0 in Table 7.3.1.1.2-25 or value "00" in Table 7.3.1.1.1.2-26 described in Clause 7.3.1 of [5,TS38.212].

[0200] Table 5: PTRS-DMRS association for UL PTRS port 0 or Second PTRS-DMRS association

[0201] (Table 7.3.1.1.2-25: PTRS-DMRS association or Second PTRS-DMRS association for UL PTRS port 0)

[0202] Table 6: PTRS-DMRS association of UL PTRS port 0 or actual UL PTRS port

[0203] (Table 7.3.1.1.2-25A:PTRS-DMRS association for UL PTRS port 0 or for the actual UL PT-RS port)

[0204] For example, the "SRS resource indicator field and / or Precoding information and number of layers" shown in Table 6 corresponds to the "second parameter and / or first parameter" mentioned in this application; the "Second SRS resource indicator field and / or Second Precoding information field" corresponds to the "fourth parameter and / or third parameter" mentioned in this application.

[0205] Table 7: PTRS-DMRS association or second PTRS-DMRS association for UL PTRS ports 0 and 1

[0206] (Table 7.3.1.1.2-26:PTRS-DMRS association or Second PTRS-DMRS association for UL PTRS ports 0 and 1)

[0207] For example, the expression "1st DMRS port which shares PTRS port 0" shown in Table 7 can also be replaced with "1st scheduled DMRS port which shares PTRS port 0", etc. The replacement methods for other contents shown in Table 7 are similar to the above contents and are not listed one by one here.

[0208] In some embodiments, when the terminal device is configured to apply the first transmission configuration indication state (TCI state) and the second transmission configuration indication state (TCI state) to send the PUSCH, the terminal device is configured with a multi-panel scheme (multipanelScheme) and the multi-panel scheme (multipanelScheme) indicates the use of the spatial division multiplexing (SDM) scheme, and the terminal device is configured with the sixth parameter (maxNrofPortsforSDM) as 2 PT-RS ports, the number of PT-RS ports actually applied is 2.

[0209] For example, the statement “the number of PT-RS ports actually used is 2” can also be replaced with “the actual number of PT-RS ports is 2”.

[0210] For example, when "multipanelScheme" is configured as SDMScheme and the value in the field "applyIndicatedTCIState" is configured as "both", if the sixth parameter "maxNrofPortsforSDM" is configured as 2 PT-RS ports, the actual number of PT-RS ports is 2.

[0211] Therefore, when the terminal device is configured to apply the first transmission configuration indication state (TCI state) and the second transmission configuration indication state (TCI state) to send the PUSCH, the actual number of PT-RS ports can be directly determined according to the sixth parameter "maxNrofPortsforSDM", and the device behavior of the terminal device is clearly defined. Therefore, it is possible to avoid ambiguity between the terminal device and the network device in the understanding of the transmission parameters actually applied to the configured grant Type 1 PUSCH, thereby avoiding PUSCH transmission failure and achieving reliable transmission of uplink data.

[0212] In some embodiments, the terminal device is configured with a first list (dl-OrJointTCI-StateList), and the terminal device has two indicated transmission configuration indication states (TCI states).

[0213] For example, the above description is applicable to terminal devices that support mTRP unified TCI. The conditions that the terminal device needs to meet to support mTRP unified TCI include: the terminal device is configured with the first list (dl-OrJointTCI-StateList) and has two indicated TCI states.

[0214] For example, "configured with dl-OrJointTCI-StateList" indicates that the terminal device supports unified TCI, and "the terminal device maintains two indicated TCI states" indicates that the terminal device supports mTRP unified TCI. The "two indicated TCI states" can be indicated by downlink DCI and / or MAC CE. For the downlink DCI and / or MAC CE, reference can be made to the relevant technologies in mTRP unified TCI, and this application does not impose any restrictions on this.

[0215] Therefore, when the terminal device is configured with the first list (dl-OrJointTCI-StateList) and the terminal device has two indicated transmission configuration indication states (TCI state), the transmission parameters actually applied to the configured grant Type 1 PUSCH can be determined according to the above method, thereby avoiding PUSCH transmission failure and achieving reliable transmission of uplink data.

[0216] The above embodiments are merely exemplary of the present invention, but the present invention is not limited thereto. Appropriate modifications may be made based on the above embodiments. For example, the above embodiments may be used alone, or one or more of the above embodiments may be combined.

[0217] As can be seen from the above embodiment, when the terminal device is configured to apply the first TCI state or the second TCI state to send PUSCH, the terminal device sends PUSCH according to the first TPMI and / or the first SRI. This can avoid ambiguity between the terminal device and the network device in understanding the transmission parameters actually applied to the configured grant Type 1 PUSCH, thereby avoiding PUSCH transmission failure and achieving reliable transmission of uplink data.

[0218] Embodiments of the second aspect

[0219] The embodiment of the present application provides a data receiving method, which is applied to a network device. The embodiment of the present application can be combined with the embodiment of the first aspect, or can be implemented independently. The contents that are the same as those of the embodiment of the first aspect are not repeated here.

[0220] FIG8 is a schematic diagram of a data receiving method according to an embodiment of the present application. As shown in FIG8 , the method includes:

[0221] 801, the network device configures the terminal device to apply a first transmission configuration indication state (TCI state) and / or a second transmission configuration indication state (TCI state);

[0222] 802. The network device receives a physical uplink shared channel (PUSCH) corresponding to configuration authorization type 1 sent by the terminal device; wherein, when the terminal device is configured to apply the first transmission configuration indication state (TCI state) or the second transmission configuration indication state (TCI state) to send the physical uplink shared channel (PUSCH), the terminal device sends the physical uplink shared channel (PUSCH) according to the first transmission precoding matrix indication information (TPMI, Transmission Precoding Matrix Indicator) and / or the first SRS resource indication information (SRI, SRS Resource Indicator).

[0223] Thus, when the terminal device is configured to apply the first TCI state or the second TCI state to send PUSCH, the terminal device sends PUSCH according to the first TPMI and / or the first SRI. This can avoid ambiguity between the terminal device and the network device in understanding the transmission parameters actually applied to the configured grant Type 1 PUSCH, thereby avoiding PUSCH transmission failure and achieving reliable transmission of uplink data.

[0224] It is worth noting that FIG8 above is merely a schematic illustration of an embodiment of the present application, and the present application is not limited thereto. For example, the execution order of the various operations may be appropriately adjusted, and other operations may be added or some operations may be reduced. Those skilled in the art may make appropriate modifications based on the above description, and are not limited to the description of FIG8 above.

[0225] In some embodiments, receiving the PUSCH corresponding to the configured authorization type 1 sent by the terminal device also includes: when the terminal device is configured to apply the first transmission configuration indication state (TCI state) and the second transmission configuration indication state (TCI state) to send the PUSCH, receiving the PUSCH sent by the terminal device according to the first transmission precoding matrix indication information (TPMI) and the second transmission precoding matrix indication information (TPMI), and / or according to the first SRS resource indication information (SRI) and the second SRS resource indication information (SRI).

[0226] In some embodiments, the method further includes: configuring a multi-panel scheme for the terminal device; or, not configuring a multi-panel scheme for the terminal device; wherein the multi-panel scheme indicates the use of a spatial division multiplexing (SDM) scheme or a single frequency network (SFN) scheme.

[0227] The above embodiments are merely exemplary of the present invention, but the present invention is not limited thereto. Appropriate modifications may be made based on the above embodiments. For example, the above embodiments may be used alone, or one or more of the above embodiments may be combined.

[0228] As can be seen from the above embodiment, when the terminal device is configured to apply the first TCI state or the second TCI state to send PUSCH, the terminal device sends PUSCH according to the first TPMI and / or the first SRI. This can avoid ambiguity between the terminal device and the network device in understanding the transmission parameters actually applied to the configured grant Type 1 PUSCH, thereby avoiding PUSCH transmission failure and achieving reliable transmission of uplink data.

[0229] Embodiments of the third aspect

[0230] The embodiment of the present application provides a data transmission device, which may be, for example, a terminal device, or one or more components or assemblies configured in the terminal device; in addition, the same contents as those in the embodiment of the first aspect are not repeated here.

[0231] FIG9 is a schematic diagram of a data transmission device according to an embodiment of the present application. As shown in FIG9 , the data transmission device 900 includes:

[0232] A first configuration unit 901, configured to apply a first transmission configuration indication state (TCI state) and / or a second transmission configuration indication state (TCI state);

[0233] a transmitting unit 902 configured to transmit a physical uplink shared channel (PUSCH) corresponding to a configuration grant type 1 according to the first transmission configuration indication state (TCI state) and / or the second transmission configuration indication state (TCI state);

[0234] In which, when the first configuration unit 901 is configured to apply the first transmission configuration indication state (TCI state) or the second transmission configuration indication state (TCI state) to send the physical uplink shared channel (PUSCH), the sending unit 902 sends the physical uplink shared channel (PUSCH) according to the first transmission precoding matrix indication information (TPMI) and / or the first SRS resource indication information (SRI).

[0235] Thus, when the terminal device is configured to apply the first TCI state or the second TCI state to send PUSCH, the terminal device sends PUSCH according to the first TPMI and / or the first SRI. This can avoid ambiguity between the terminal device and the network device in understanding the transmission parameters actually applied to the configured grant Type 1 PUSCH, thereby avoiding PUSCH transmission failure and achieving reliable transmission of uplink data.

[0236] In some embodiments, when the first configuration unit 901 is configured to apply a first transmission configuration indication state (TCI state) or a second transmission configuration indication state (TCI state) to send the physical uplink shared channel (PUSCH): the first transmission precoding matrix indication information (TPMI) is configured by a first parameter, and / or the first SRS resource indication information (SRI) is configured by a second parameter.

[0237] In some embodiments, when the first configuration unit 901 is configured to apply the first transmission configuration indication state (TCI state) or the second transmission configuration indication state (TCI state) to send the physical uplink shared channel (PUSCH): the terminal device is configured with the first parameter and / or the second parameter, or the terminal device is configured with the first parameter and the third parameter, and / or the terminal device is configured with the second parameter and the fourth parameter.
