[0042] For example, a communication system 100 used in an embodiment of the present application is shown in FIG1 . The communication system 100 may include a network device 110, which may be a device that communicates with a terminal device 120 (or a communication terminal or terminal). The network device 110 may provide communication coverage for a specific geographic area and may communicate with terminal devices within the coverage area.

[0044] Optionally, the communication system 100 may further include other network entities such as a network controller and a mobility management entity, which is not limited in the embodiment of the present application.

[0045] It should be understood that in the embodiments of the present application, a device having a communication function in a network / system may be referred to as a communication device. Taking the communication system 100 shown in FIG1 as an example, the communication device may include a network device 110 and a terminal device 120 having a communication function. The network device 110 and the terminal device 120 may be the specific devices described above and will not be described in detail here. The communication device may also include other devices in the communication system 100, such as a network controller, a mobility management entity, and other network entities, which are not limited in the embodiments of the present application.

[0046] It should be understood that the terms "system" and "network" are often used interchangeably herein. The term "and / or" is simply a description of an association between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " generally indicates that the related objects are in an "or" relationship.

[0047] It should be understood that the "indication" mentioned in the embodiments of this application can be a direct indication, an indirect indication, or an indication of an association. For example, "A indicates B" can mean that A directly indicates B, for example, B can be obtained through A; it can also mean that A indirectly indicates B, for example, A indicates C, and B can be obtained through C; it can also mean that there is an association between A and B.

[0048] In the description of the embodiments of the present application, the term "corresponding" may indicate a direct or indirect correspondence between the two, or an association relationship between the two, or a relationship between indication and being indicated, configuration and being configured, etc.

[0049] In the embodiments of the present application, "pre-defined" may be implemented by pre-storing corresponding codes, tables, or other methods that can be used to indicate relevant information in a device (e.g., a terminal device or a network device). The present application does not limit the specific implementation method. For example, pre-defined may refer to information defined in a protocol.

[0050] In the embodiments of the present application, the "protocol" may refer to a standard protocol in the communication field, for example, it may include an LTE protocol, an NR protocol, and related protocols used in future communication systems, and this application does not limit this.

[0051] To facilitate a better understanding of the embodiments of the present application, a transmission scheme of multiple downlink transmission reception points (TRP) related to the present application is described.

[0052] The NR system introduces non-coherent transmission based on downlink and uplink of multiple TRPs. The ideal backhaul connection between TRPs can be ideal or non-ideal. Under ideal backhaul, TRPs can exchange information quickly and dynamically. Under non-ideal backhaul, TRPs can only exchange information quasi-statically due to the large delay. In downlink non-coherent transmission, multiple TRPs can use different control channels to independently schedule multiple physical downlink shared channels (PDSCH) of a terminal, or use the same control channel to schedule the transmission of different TRPs, where the data of different TRPs use different transmission layers. The latter can only be used in the case of ideal backhaul.

[0053] The network device can schedule the terminal device to transmit the Physical Uplink Shared Channel (PUSCH) to two TRPs through a single downlink control information (DCI). The PUSCH transmitted to the two TRPs can be configured with independent transmission parameters, such as beams and precoding matrices, and the number of transmission layers of the PUSCH transmitted to the two TRPs is the same. In some scenarios, the PUSCH transmitted to the two TRPs is transmitted in a time division multiplexing (TDM) manner. The PUSCH transmitted by the terminal device to different TRPs is aligned with the corresponding TRP for simulated beamforming, thereby distinguishing different PUSCHs through the spatial domain and providing uplink spectrum efficiency. For codebook-based PUSCH transmission, the single DCI needs to include two sounding reference signal resource indicator (SRS resource indicator, SRI) fields and two precoding information and layer number (Precoding information and number of layers) fields, where the network device configures two sounding reference signal resource sets (SRS resource set) SRS, and the first SRI field and the second SRI field correspond to two SRS resource sets, which are used to indicate the beam direction of the PUSCH transmitted to the two TRPs. The second precoding information and layer number field only needs to indicate the precoding information, and the number of layers defaults to the same as the number of layers indicated by the first precoding information and layer number field. For non-codebook-based PUSCH transmission, the single DCI needs to include two SRI fields, where the first SRI field is used to indicate the beam direction and number of transmission layers of the PUSCH, and the second SRI field is used to indicate the beam direction of the PUSCH, and the number of transmission layers field is the same as the number of transmission layers indicated by the first SRI. In the above description, the beam direction of the PUSCH is the same as the beam direction of the SRS resource indicated by the SRI.

[0054] The network device can also schedule the terminal device to transmit PUSCH to two TRPs through multiple DCIs. The multiple DCIs can be carried by different control resource sets (CORESETs). Specifically, the network device side configures multiple CORESET groups, and each TRP is scheduled using the CORESET in its own CORESET group, that is, different TRPs can be distinguished by the CORESET group. For example, the network device can configure a CORESET group index for each CORESET, and different indexes correspond to different TRPs.

[0055] In some scenarios, PDSCHs from two TRPs scheduled by single DCI (s-DCI) can be distinguished by the transmission configuration indicator (TCI) state (TCI state). One state of the TCI information field in DCI can be mapped to up to two TCI states, and each TCI state corresponds to one of the PDSCHs transmitted using frequency-division multiplexing (FDM) or spatial division multiplexing (SDM).

[0056] Due to the different spatial positions of different TRPs, the large-scale characteristics of the channels corresponding to each TRP are significantly different. Therefore, when multiple TRPs are transmitted jointly, it is necessary to indicate the quasi-co-located (QCL) information corresponding to each TRP separately. In some cases, one state of the TCI information field in the DCI only corresponds to one TCI state. In order to support transmission based on multiple TRPs, the Media Access Control Control Element (MAC CE) signaling is enhanced, that is, one state of the TCI information field in the DCI can be mapped to at most two TCI states. If the TCI information field indicated in the DCI indicates two TCI states, the PDSCH associated with the first TCI state will be transmitted using the DMRS port indicated in the first Code Division Multiplexing (CDM) group, and the PDSCH associated with the second TCI state will be transmitted using the DMRS port indicated in the second CDM group. The beam direction of the PDSCH is the same as the beam direction of the synchronization signal block (SSB) or the channel state information reference signal (CSI-RS) corresponding to the TCI state.

[0057] The configuration and indication of TCI status includes three steps: Radio Resource Control (RRC) configuration, MAC CE activation, and DCI indication. The specific process is as follows:

[0058] The RRC configures a maximum of M TCI states for the terminal through PDSCH configuration (PDSCH-Config), where the value of M is determined by the UE capability and the maximum value of M can be 128.

[0059] The MAC CE activates up to eight TCI state groups for mapping to the 3-bit TCI information field in the DCI. Each TCI state group activated by the MAC CE can contain one or two TCI states. If the higher-layer parameter configuration DCI includes a TCI indication field, DCI format 1_1 can indicate a TCI state group from the TCI state groups activated by the MAC. If the higher-layer parameter configuration DCI does not include a TCI indication field or data is scheduled using DCI format 1_0, the DCI will not include a TCI state indication field.

[0060] Among them, a TCI state can include the following configurations:

[0061] TCI state ID, used to identify a TCI state;

[0062] QCL information 1;

[0063] QCL information 2.

[0064] Among them, a QCL information contains the following information:

[0065] QCL type configuration, which can be one of QCL type A, QCL type B, QCL type C, and QCL type D;

[0066] The QCL reference signal configuration includes the cell ID where the reference signal is located, the Band Width Part (BWP) ID, and the reference signal information (which can be the Channel State Information Reference Signal (CSI-RS) resource ID or the Synchronization Signal Block (SSB) index).

[0067] The definitions of different QCL type configurations are as follows:

[0068] 'QCL-TypeA': {Doppler shift, Doppler spread, average delay, delay spread};

[0069] 'QCL-TypeB': {Doppler shift, Doppler spread};

[0070] 'QCL-TypeC': {Doppler shift, average delay};

[0071] 'QCL-TypeD': {Spatial Rx parameter}.

[0072] To facilitate a better understanding of the embodiments of the present application, the transmission scheme of the uplink multi-TRP or antenna panel related to the present application is described.

[0073] If a terminal device is configured with multiple panels and supports simultaneous uplink information transmission on multiple panels, multiple uplink information can be sent simultaneously on multiple panels, as shown in Figure 2, to improve uplink spectrum efficiency. Uplink transmission of multiple panels or TRPs can be scheduled via a single DCI or multiple DCIs. The multiple PUSCHs sent by the terminal device can be in a unified TCI (unified TCI state) scenario. Multiple PUSCHs are associated with different TCI states and can be non-overlapping, partially overlapping, or completely overlapping in the time domain.

[0074] In some scenarios, terminal devices also need to transmit unscheduled PUSCH, such as Type 1 unscheduled PUSCH or Type 2 unscheduled PUSCH. Type 1 unscheduled PUSCH is configured via RRC and does not require DCI detection. Type 2 unscheduled PUSCH is scheduled and configured via RRC and activated and deactivated via DCI. In this case, how to transmit unscheduled PUSCH is an urgent problem that needs to be solved.

[0075] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The above related technologies can be combined arbitrarily with the technical solutions of the embodiments of the present application as optional solutions, and all of them fall within the scope of protection of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0076] FIG3 is a schematic interaction diagram of a wireless communication method 200 according to an embodiment of the present application. As shown in FIG3 , the method 200 includes at least part of the following:

[0077] S210, the terminal device sends one or more scheduling-free physical uplink shared channels PUSCH, wherein the multiple scheduling-free PUSCHs are associated with different spatial parameters.

[0079] For example, when the terminal device sends a scheduling-free PUSCH, the scheduling-free PUSCH may be a type 1 or type 2 scheduling-free PUSCH.

[0080] For another example, when the terminal device sends multiple scheduling-free PUSCHs, the multiple scheduling-free PUSCHs may include type 1 scheduling-free PUSCHs and / or type 2 scheduling-free PUSCHs. That is, the multiple scheduling-free PUSCHs may all be type 1 scheduling-free PUSCHs, or may all be type 2 scheduling-free PUSCHs, or may include both type 1 scheduling-free PUSCHs and type 2 scheduling-free PUSCHs.

[0081] In some embodiments, the spatial parameter may refer to a spatial setting or a spatial relation for PUSCH transmission.

[0082] In some embodiments, the spatial parameters include, but are not limited to, at least one of the following:

[0083] Reference signal set information, Transmission Configuration Indicator (TCI) status information, antenna panel information, control resource set group (coresetPoolIndex) information, beam information.

[0086] In some embodiments, the CORESET group information may include a control resource set pool index (coresetPoolIndex).

[0088] In the embodiment of the present application, the beam may also be referred to as a spatial domain filter (Spatial domain filter or Spatial domain filter), or a spatial receive parameter (Spatial Rx parameter).

[0093] In some embodiments, the association of PUSCH and antenna panel information may refer to:

[0094] The PUSCH is transmitted through the antenna panel indicated by the antenna panel information.

[0095] In some embodiments, associating the PUSCH with the control resource set group information may refer to:

[0096] The CORESET group indicated by the control resource set group information is the CORESET group configured by the higher layer signaling for resources to send PUSCH.

[0097] In some embodiments, associating uplink information with beam information may include:

[0098] The PUSCH is transmitted through the beam indicated by the beam information.

[0099] In some embodiments, multiple scheduling-free PUSCHs associated with different spatial parameters may refer to:

[0100] Multiple scheduling-free PUSCHs are associated with multiple spatial parameters, where each scheduling-free PUSCH is associated with one spatial parameter, and different scheduling-free PUSCHs are associated with different spatial parameters. For example, the multiple scheduling-free PUSCHs include a first PUSCH and a second PUSCH, where the first PUSCH is associated with a first spatial parameter, and the second PUSCH is associated with a second spatial parameter, and the first spatial parameter and the second spatial parameter are different.

[0101] In some embodiments, the first spatial parameter includes at least one of the following:

[0102] First reference signal set, first TCI state, first antenna panel (e.g., panel1), first CORESET group, first beam.

[0103] In some embodiments, the second spatial parameter includes at least one of the following:

[0104] Second reference signal set, second TCI state, second antenna panel (e.g., panel2), second CORESET group, second beam.

[0105] Embodiment 1: multiple scheduling-free PUSCHs are configured using the same high-layer parameter.

[0106] For example, the transmission parameters of the multiple scheduling-free PUSCHs may be configured through the same high-level parameter. Specifically, for example, the transmission parameters of the multiple scheduling-free PUSCHs may be carried in one information element (IE).

[0107] For another example, the spatial parameters of the multiple scheduling-free PUSCHs may be configured through the same high-level parameter. Specifically, for example, the spatial parameters of the multiple scheduling-free PUSCHs may be carried in one IE.

[0108] For another example, the transmission parameters and spatial parameters of the multiple scheduling-free PUSCHs may be configured through the same high-level parameter. Specifically, for example, the transmission parameters and spatial parameters of the multiple scheduling-free PUSCHs may be carried in one IE.

[0109] Optionally, the transmission parameters of the scheduling-free PUSCH include but are not limited to at least one of the following:

[0110] PUSCH time domain offset, PUSCH time domain allocation information, PUSCH frequency domain allocation information, PUSCH antenna port, PUSCH precoding information and number of layers.

[0111] In some embodiments, multiple scheduling-free PUSCHs are associated with different SRS resource set indices (SRS-ResourceSetId).

[0112] For example, multiple unscheduled PUSCHs include n unscheduled PUSCHs, where the SRS resource set indexes associated with the n unscheduled PUSCHs are index 0, index 1, ..., index n-1, which can also be recorded as the first SRS resource set, ..., the nth SRS resource set.

[0113] In some embodiments, multiple scheduling-exempt PUSCHs overlap in the time domain.

[0114] For example, multiple unscheduled PUSCHs include two unscheduled PUSCHs, recorded as the first PUSCH and the second PUSCH. Then, the overlap of multiple unscheduled PUSCHs in the time domain may include the overlap of the time domain resources of the first PUSCH and the time domain resources of the second PUSCH. For example, the time domain symbols occupied by the first PUSCH and the second PUSCH overlap.

[0115] In some embodiments, the time domain resources of the first PUSCH are configured by first time domain resource configuration information (timeDomainAllocation), and the time domain resources of the second PUSCH are configured by second time domain resource configuration information (timeDomainAllocation2).

[0116] The time domain resources configured by the first time domain resource configuration information and the second time domain resource configuration information overlap, for example, the time domain symbols overlap.

[0117] In some embodiments, the frequency domain resources of the first PUSCH are configured by first frequency domain resource configuration information (frequencyDomainAllocation), and the frequency domain resources of the second PUSCH are configured by second frequency domain resource configuration information (frequencyDomainAllocation2).

[0118] In some embodiments, the precoding information and number of layers of multiple scheduling-free PUSCHs are configured separately.

[0119] For example, multiple scheduling-free PUSCHs include a first PUSCH and a second PUSCH, the precoding information and number of layers of the first PUSCH are configured through first precoding and layer configuration information (precodingAndNumberOfLayers), and the precoding information and number of layers of the second PUSCH are configured through second precoding and layer configuration information (precodingAndNumberOfLayers2).

[0120] In some embodiments, precoding and layer number information of the first PUSCH are associated with a first SRS resource set, and precoding and layer number information of the second PUSCH are associated with a second SRS resource set.

[0121] Optionally, the sum of the number of transmission layers configured by the first precoding and layer configuration information and the second precoding and layer configuration information does not exceed 4, or the sum of the number of transmission layers configured by the first precoding and layer configuration information and the second precoding and layer configuration information does not exceed 2.

[0122] In some embodiments, SRS resource indicators (srs-ResourceIndicator) of multiple scheduling-free PUSCHs are configured separately.

[0123] For example, the multiple scheduling-free PUSCHs include a first PUSCH and a second PUSCH, the SRS resources corresponding to the first PUSCH are configured through a first SRS resource indication, and the SRS resources corresponding to the second PUSCH are configured through a second SRS resource indication.

[0124] The first SRS resource indication is used to indicate a first SRS resource, and the second SRS resource indication is used to indicate a second SRS resource. The first SRS resource indicated by the first SRS resource indication belongs to a first SRS resource set, and the second SRS resource indicated by the second SRS resource indication belongs to a second SRS resource set.

[0125] In some embodiments, the phase-tracking reference signals (PTRS) port index (e.g., ptrs-PortIndex) associated with the first SRS resource is different from the PTRS port index (e.g., ptrs-PortIndex2) associated with the second SRS resource. In some embodiments, the multiple scheduling-free PUSCHs include at least one codebook-based PUSCH and / or at least one non-codebook-based PUSCH. That is, the multiple scheduling-free PUSCHs may all be codebook-based PUSCHs, may all be non-codebook-based PUSCHs, may be partly codebook-based PUSCHs, and may partly be non-codebook-based PUSCHs.

[0126] Optionally, when multiple scheduling-free PUSCHs include a non-codebook-based PUSCH, such as the first PUSCH, the PTRS ports associated with one or more SRS resources corresponding to the first PUSCH are the same, that is, correspond to the same ptrs-PortIndex.

[0127] In some embodiments, multiple unscheduled PUSCHs are associated with corresponding PTRSs, such as a first PTRS and a second PTRS. The port of the first DMRS associated with the port of the first PTRS is determined according to a predefined rule. The port of the second DMRS associated with the port of the second PTRS is determined according to a predefined rule.

[0128] In some implementations, the predefined rule is to apply the association relationship between the PTRS and the DMRS corresponding to the preset state in the PTRS-DMRS association information field in the DCI. The preset state can be any state. For example, the port of the first DMRS associated with the port of the first PTRS is determined according to the state '0' or state '00' in the PTRS-DMRS association information field. For example, the port of the second DMRS associated with the port of the second PTRS is determined according to the state '1' or state '01' or state '11' in the PTRS-DMRS association information field. Optionally, the correspondence between the state value of the PTRS-DMRS association information field and the DMRS port associated with the PTRS port can be as shown in Table 1 or Table 2.

[0129] In other implementations, the predefined rule is to apply a default DMRS port. For example, the first DMRS port associated with the first PTRS port is the first DMRS port associated with PTRS port 0, or the first DMRS port associated with the first PTRS port is the first DMRS port associated with PTRS port 0 and the first DMRS port associated with PTRS port 1. For example, the second DMRS port associated with the second PTRS port is the second DMRS port associated with PTRS port 0, or the second DMRS port associated with the second PTRS port is the second DMRS port associated with PTRS port 0 and the second DMRS port associated with PTRS port 1.

[0130] Optionally, the port of the first DMRS is different from the port of the second DMRS.

[0133] In some embodiments, the maximum number of transmission layers corresponding to the multiple scheduling-free PUSCHs is configured separately. In this case, the maximum number of transmission layers corresponding to the multiple scheduling-free PUSCHs can be the same or different.

[0134] In other embodiments, the maximum number of transmission layers corresponding to multiple scheduling-free PUSCHs is configured through the same high-layer parameter.

[0135] In this case, the maximum number of transmission layers corresponding to the multiple scheduling-free PUSCHs may be the same.

[0136] Therefore, when multiple scheduling-free PUSCHs are all type 1 scheduling-free PUSCHs, an embodiment of the present application provides a method for configuring the transmission parameters of the multiple PUSCHs, for example, using independent precoding information and number of layers, using an independent maximum number of transmission layers configuration or the same maximum number of transmission layers configuration, etc.

[0137] In some embodiments, multiple scheduling-free PUSCHs include a first PUSCH and a second PUSCH, the first PUSCH is associated with a first SRS resource set, the second PUSCH is associated with a second SRS resource set, the first SRS resource set is associated with a first control resource set, the second SRS resource set is associated with a second control resource set, and the index of the first control resource set is different from the index of the second control resource set.

[0138] In some embodiments, the index of the first control resource set and the index of the second control resource set are predefined or configured by the network device.

[0139] For example, if the index of the first control resource set and the index of the second control resource set can be predefined, the first SRS resource set is associated with the control resource set with an index of 0, and the second SRS resource set is associated with the control resource set with an index of 1.

[0140] For another example, if the index of the first control resource set and the index of the second control resource set are configured by the network device, the index of the control resource set associated with the SRS resource set can be configured in the configuration information of the SRS resource set, or both the control resource set index and the associated SRS resource set index can be configured in the configured uplink grant (ConfiguredUplinkGrant).

[0141] The following describes the RRC structure design for carrying transmission parameters and spatial parameters of multiple scheduling-free PUSCHs with reference to specific examples.

[0142] Example 1:

[0143] Among them, srs-ResourceSetId is used to configure the SRS resource set of the first PUSCH, and srs-ResourceSetId2 is used to configure the SRS resource set of the second PUSCH; timeDomainOffset is used for the time domain offset of the first PUSCH, and timeDomainOffset2 is used to configure the time domain offset of the second PUSCH; timeDomainAllocation is used to configure the time domain allocation of the first PUSCH, and timeDomainAllocation2 is used to configure the time domain allocation of the second PUSCH; frequencyDomainAllocation is used to configure the frequency domain allocation of the first PUSCH, and frequencyDomainAllocation2 is used to configure the time domain allocation of the second PUSCH; frequencyDomainAllocation is used to configure the frequency domain allocation of the first PUSCH, and frequencyDomainAllocation2 is used to configure the time domain allocation of the second PUSCH. omainAllocation2 is used to configure the frequency domain allocation of the second PUSCH; antennaPort is used to configure the antenna port of the first PUSCH, and antennaPort2 is used to configure the antenna port of the second PUSCH; precodingAndNumberOfLayers is used to configure the precoding information and number of layers of the first PUSCH, and precodingAndNumberOfLayers2 is used to configure the precoding information and number of layers of the second PUSCH; srs-ResourceIndicator is used to configure the SRS resources corresponding to the first PUSCH, and srs-ResourceIndicator2 is used to configure the SRS resources corresponding to the second PUSCH.

[0144] Example 2:

[0145] Among them, srs-ResourceSetId is used to configure the SRS resource set of the first PUSCH, and srs-ResourceSetId2 is used to configure the SRS resource set of the second PUSCH; coresetPoolIndex1 is used to configure the control resource set group of the first PUSCH, and coresetPoolIndex2 is used to configure the control resource set group of the second PUSCH; timeDomainOffset is used for the time domain offset of the first PUSCH, and timeDomainOffset2 is used to configure the time domain offset of the second PUSCH; timeDomainAllocation is used to configure the time domain allocation of the first PUSCH, and timeDomainAllocation2 is used to configure the time domain allocation of the second PUSCH; frequencyDomainA llocation is used to configure the frequency domain allocation of the first PUSCH, frequencyDomainAllocation2 is used to configure the frequency domain allocation of the second PUSCH; antennaPort is used to configure the antenna port of the first PUSCH, antennaPort2 is used to configure the antenna port of the second PUSCH; precodingAndNumberOfLayers is used to configure the precoding information and number of layers of the first PUSCH, precodingAndNumberOfLayers2 is used to configure the precoding information and number of layers of the second PUSCH; srs-ResourceIndicator is used to configure the SRS resources corresponding to the first PUSCH, and srs-ResourceIndicator2 is used to configure the SRS resources corresponding to the second PUSCH.

[0146] Example 3:

[0147] Among them, srs-ResourceSetId is used to configure the SRS resource set of the first PUSCH, and srs-ResourceSetId2 is used to configure the SRS resource set of the second PUSCH; coresetPoolIndex1 is used to configure the control resource set group associated with the SRS resource set of the first PUSCH, and coresetPoolIndex2 is used to configure the control resource set group associated with the SRS resource set of the second PUSCH.

[0148] It should be noted that in the above examples, Example 1 and Example 3 can be used in combination, that is, the terminal device can obtain the transmission parameters and spatial parameters corresponding to the first PUSCH and the second PUSCH according to the parameters in Example 1 and Example 3. Example 2 can be used alone, that is, the terminal device can obtain the transmission parameters and spatial parameters corresponding to the first PUSCH and the second PUSCH according to the parameters in Example 2.

[0149] Therefore, when multiple scheduling-free PUSCHs are all type 1 scheduling-free PUSCHs, an embodiment of the present application provides a method for configuring the spatial parameters of the multiple PUSCHs, and the spatial parameters of the multiple PUSCHs and the transmission parameters of the multiple PUSCHs can be associated, or can be configured independently, thereby improving the flexibility of the configuration.

[0150] Embodiment 2: Multiple scheduling-free PUSCHs are configured through different higher layer parameters.

[0151] For example, the multiple scheduling-free PUSCHs include a first PUSCH and a second PUSCH, the transmission parameters and spatial parameters of the first PUSCH are configured by first high-level parameters, and the transmission parameters and high-level parameters of the second PUSCH are configured by second high-level parameters.

[0152] Optionally, when the multiple scheduling-free PUSCHs are respectively configured through multiple high-level parameters, the multiple scheduling-free PUSCHs configured by the multiple high-level parameters may have the characteristics described in Example 1.

[0153] For example, multiple scheduling-free PUSCHs are associated with different SRS resource set indexes.

[0154] For another example, multiple scheduling-free PUSCHs overlap in the time domain.

[0155] For another example, the precoding information and number of layers of multiple scheduling-free PUSCHs are independently configured.

[0156] For another example, SRS resource indicators of multiple scheduling-free PUSCHs are configured separately.

[0157] For another example, the multiple scheduling-free PUSCHs may include at least one codebook-based PUSCH and / or at least one non-codebook-based PUSCH.

[0158] For another example, the maximum number of transmission layers corresponding to multiple scheduling-free PUSCHs may be configured separately, or may be configured through the same high-layer parameter.

[0159] The following describes the RRC structure design for carrying transmission parameters and spatial parameters of multiple scheduling-free PUSCHs with reference to specific examples.

[0160] Example 4:

[0161] Among them, the multiple unscheduled PUSCHs include a first PUSCH and a second PUSCH, rrc-ConfiguredUplinkGrant1 is used to configure the transmission parameters and spatial parameters of the first PUSCH, and rrc-ConfiguredUplinkGrant2 is used to configure the transmission parameters and spatial parameters of the second PUSCH. The functions of the parameters included in rrc-ConfiguredUplinkGrant1 refer to the relevant description in Example 1. For the sake of brevity, they are not repeated here. The functions of the parameters included in rrc-ConfiguredUplinkGrant2 refer to the relevant description in Example 1. For the sake of brevity, they are not repeated here.

[0162] Example 5:

[0163] Among them, the multiple unscheduled PUSCHs include a first PUSCH and a second PUSCH, rrc-ConfiguredUplinkGrant1 is used to configure the transmission parameters and spatial parameters of the first PUSCH, and rrc-ConfiguredUplinkGrant2 is used to configure the transmission parameters and spatial parameters of the second PUSCH. The functions of the parameters included in rrc-ConfiguredUplinkGrant1 refer to the relevant description in Example 2, which is not repeated here for the sake of brevity. The functions of the parameters included in rrc-ConfiguredUplinkGrant2 refer to the relevant description in Example 2, which is not repeated here for the sake of brevity.

[0164] Example 6:

[0165] Among them, srs-ResourceSetId is used to configure the SRS resource set of the first PUSCH, and srs-ResourceSetId2 is used to configure the SRS resource set of the second PUSCH; coresetPoolIndex1 is used to configure the control resource set group associated with the SRS resource set of the first PUSCH, and coresetPoolIndex2 is used to configure the control resource set group associated with the SRS resource set of the second PUSCH.

[0166] It should be noted that in the above examples, Example 4 and Example 6 can be used in combination, that is, the terminal device can obtain the transmission parameters and spatial parameters corresponding to the first PUSCH and the second PUSCH according to the parameters in Example 4 and Example 6. Example 5 can be used alone, that is, the terminal device obtains the transmission parameters and spatial parameters corresponding to the first PUSCH and the second PUSCH according to the parameters in Example 5.

[0167] Therefore, when multiple scheduling-free PUSCHs are all type 1 scheduling-free PUSCHs, an embodiment of the present application provides a method for configuring the spatial parameters of the multiple PUSCHs, and the spatial parameters of the multiple PUSCHs and the transmission parameters of the multiple PUSCHs can be associated, or can be configured independently, thereby improving the flexibility of the configuration.

[0168] In some embodiments of the present application, when the terminal device has configuration information of multiple scheduling-free PUSCHs (that is, the terminal device has multiple scheduling-free configuration information), the method 200 further includes:

[0169] Determine, according to the first instruction information of the network device, to send a PUSCH without scheduling, or switch to sending a PUSCH without scheduling; or,

[0170] When a preset condition is met, it is determined to send a PUSCH without scheduling, or switched to sending a PUSCH without scheduling.

[0171] The one PUSCH exempted from scheduling is associated with the first spatial parameter or the second spatial parameter, that is, the one PUSCH exempted from scheduling may be the first PUSCH or the second PUSCH.

[0172] In some embodiments, the terminal device has configuration information of multiple scheduling-free PUSCHs, which may include:

[0173] The terminal device receives configuration information of multiple unscheduled PUSCHs configured by the network device. That is, the configuration information of the multiple unscheduled PUSCHs can be configured by the network device. For example, the network device can configure the configuration information through RRC parameters, and the RRC parameters can be, for example, configured grant configuration (ConfiguredGrantConfig) or RRC configured uplink grant (rrc-ConfiguredUplinkGrant).

[0174] In some embodiments, the multiple scheduling-free configuration information is used to configure the transmission of multiple scheduling-free PUSCHs, and the multiple scheduling-free configuration information is associated with different spatial parameters, that is, the multiple scheduling-free PUSCHs are associated with different spatial parameters. In other words, the terminal device needs to transmit multiple scheduling-free PUSCHs through different spatial parameters. The scheduling-free configuration information is a semi-static configuration. The terminal device can transmit multiple scheduling-free PUSCHs based on the multiple scheduling-free configuration information within a period of time. When the terminal device receives the first indication information of the network device, or when the terminal device determines that the preset conditions are met, the terminal device can switch to sending a scheduling-free PUSCH, for example, based on one of the multiple scheduling-free configuration information, to transmit the corresponding scheduling-free PUSCH.

[0175] It should be noted that the terminal device switches to sending only one unscheduled PUSCH relative to the terminal device's last transmission. If the terminal device's last transmission was based on multiple unscheduled PUSCH transmissions based on multiple unscheduled configuration information, then upon receiving the first indication information or judging that the preset conditions are met, the terminal device can switch to sending only one unscheduled PUSCH. If the terminal device's last transmission was also a unscheduled PUSCH transmission, the terminal device may not perform the switch.

[0176] Therefore, in an embodiment of the present application, when the terminal device needs to send multiple unscheduled PUSCHs, the terminal device can send only one unscheduled PUSCH according to the instructions of the network device or its own judgment, or, in other words, terminate (drop) the transmission of some unscheduled PUSCHs.

[0177] In some embodiments, when the terminal device has configuration information of multiple type 1 unscheduled PUSCHs, the terminal device switches to sending a unscheduled PUSCH according to the first indication information of the network device, or switches to sending a unscheduled PUSCH when a preset condition is met.

[0178] For example, the terminal device is configured with multiple scheduling-free configuration information, and the multiple scheduling-free configuration information is used to configure the transmission of multiple type 1 scheduling-free PUSCHs, wherein the multiple scheduling-free configuration information is associated with different spatial parameters, that is, the multiple type 1 scheduling-free PUSCHs are associated with different spatial parameters. Within a period of time, the terminal device transmits multiple type 1 scheduling-free PUSCHs based on the multiple scheduling-free configuration information. When the terminal device receives the first indication information of the network device, or when the terminal device determines that the preset conditions are met, the terminal device can switch to sending a scheduling-free PUSCH, for example, based on one of the multiple scheduling-free configuration information, the corresponding type 1 scheduling-free PUSCH is transmitted.

[0179] The network device determines whether multiple spatial parameters can be used to transmit multiple scheduling-free PUSCHs. In this way, the network device can determine whether the terminal device uses multiple spatial parameters to transmit multiple scheduling-free PUSCHs or uses a single spatial parameter to transmit one scheduling-free PUSCH based on system performance. The terminal device only needs to transmit according to the instructions of the network device, which is conducive to reducing the implementation complexity of the terminal device.

[0180] In some embodiments, the first indication information is carried in downlink signaling, and the downlink signaling may be DCI or MAC CE, etc.

[0181] It should be understood that the present application does not limit the specific indication method of the first indication information. For example, the first indication information can be used to indicate the PUSCH that needs to terminate transmission, or the PUSCH that does not need to terminate transmission, or the transmission status corresponding to each PUSCH in multiple non-scheduled PUSCHs, such as whether the transmission needs to be terminated or whether to continue transmission.

[0182] In some specific embodiments, the n states of the first indication information correspond to n unscheduled PUSCH transmissions, and each state is used to indicate that the corresponding PUSCH transmission is a PUSCH transmission that needs to be terminated, where n is a positive integer greater than 1.

[0183] For example, the multiple unscheduled PUSCHs are the first PUSCH and the second PUSCH, and the first indication information may be 1 bit, used to indicate two states, namely 0 and 1, wherein the two states are used to indicate that the first PUSCH needs to be suspended and the second PUSCH needs to be suspended. For example, state 0 is used to indicate that the first PUSCH needs to be suspended, and state 1 is used to indicate that the second PUSCH needs to be suspended.

[0184] For another example, the multiple unscheduled PUSCHs are the first PUSCH, the second PUSCH, the third PUSCH, and the fourth PUSCH. The first indication information can be 2 bits, used to indicate four states, namely 00, 01, 10, and 11. The four states are used to indicate that the first PUSCH needs to be suspended, the second PUSCH needs to be suspended, the third PUSCH needs to be suspended, and the fourth PUSCH needs to be suspended. For example, state 00 is used to indicate that the first PUSCH needs to be suspended, state 01 is used to indicate that the second PUSCH needs to be suspended, state 10 is used to indicate that the third PUSCH needs to be suspended, and state 11 is used to indicate that the fourth PUSCH needs to be suspended.

[0185] In some embodiments, the first indication information indicates, through bit mapping, the PUSCHs that need to be terminated, or the PUSCHs that do not need to be terminated, or the PUSCHs that need to continue to be transmitted among multiple non-scheduled PUSCHs.

[0186] For example, multiple unscheduled PUSCHs include a first PUSCH and a second PUSCH. The first indication information can be 2 bits (B1B0), the first bit (B0) is used to indicate whether the first PUSCH needs to be terminated, and the second bit (B1) is used to indicate whether the second PUSCH needs to be terminated. As an example, B0 is set to 1, indicating that the first PUSCH needs to be terminated, and B0 is set to 0, indicating that the first PUSCH does not need to be terminated, or needs to continue transmission. B1 is set to 1, indicating that the second PUSCH needs to be terminated, and B1 is set to 0, indicating that the second PUSCH does not need to be terminated, or needs to continue transmission.

[0187] For another example, multiple unscheduled PUSCHs include a first PUSCH, a second PUSCH, a third PUSCH, and a fourth PUSCH. The first indication information can be 4 bits (B3 to B0), B0 is used to indicate whether the first PUSCH needs to be terminated, B1 is used to indicate whether the second PUSCH needs to be terminated, B2 is used to indicate whether the third PUSCH needs to be terminated, and B3 is used to indicate whether the fourth PUSCH needs to be terminated. As an example, B0 is set to 1, indicating that the first PUSCH needs to be terminated, and B0 is set to 0, indicating that the first PUSCH does not need to be terminated, or needs to continue transmission. B1 is set to 1, indicating that the second PUSCH needs to be terminated, and B1 is set to 0, indicating that the second PUSCH does not need to be terminated, or needs to continue transmission. B2 is set to 1, indicating that the third PUSCH needs to be terminated, and B2 is set to 0, indicating that the third PUSCH does not need to be terminated, or needs to continue transmission. B3 is set to 1, indicating that the fourth PUSCH needs to be terminated, and B3 is set to 0, indicating that the fourth PUSCH does not need to be terminated, or needs to continue transmission.

[0188] In some embodiments of the present application, the method 200 further includes:

[0189] Determine whether a preset condition is met based on the first information, wherein the first information includes but is not limited to at least one of the following:

[0190] The power of multiple unscheduled PUSCHs;

[0191] Timing advance of multiple unscheduled PUSCHs;

[0192] The length of time that multiple unscheduled PUSCHs overlap in the time domain;

[0193] Interference between multiple unscheduled PUSCHs;

[0194] Signal quality of multiple unscheduled PUSCHs.

[0195] The terminal device determines whether to use multiple spatial parameters to transmit multiple unscheduled PUSCHs. On the one hand, this is beneficial to reducing the signaling overhead of the network device. On the other hand, the terminal device determines whether to use multiple spatial parameters to transmit multiple unscheduled PUSCHs based on the first information, which is beneficial to ensuring the transmission performance of the PUSCH.

[0196] In some embodiments, the preset condition includes but is not limited to at least one of the following:

[0197] A difference in power of the multiple non-scheduled PUSCHs is greater than or equal to a first threshold;

[0198] A difference between the timing advances of the multiple unscheduled PUSCHs is greater than or equal to a second threshold;

[0199] The number of symbols overlapping in the time domain by the multiple scheduling-free PUSCHs is greater than or equal to a third threshold;

[0200] A difference or a ratio between the intensity of a first PUSCH among the multiple non-scheduled PUSCHs and the intensity of interference caused by a second PUSCH on the first PUSCH is less than or equal to a fourth threshold;

[0201] A difference or a ratio between the strength of the second PUSCH among the multiple non-scheduled PUSCHs and the strength of interference caused by the first PUSCH on the second PUSCH is less than or equal to a fifth threshold;

[0202] The interference between the multiple scheduling-free PUSCHs is greater than or equal to a sixth threshold;

[0203] A difference or a ratio of signal qualities of the multiple scheduling-free PUSCHs is greater than or equal to a seventh threshold.

[0204] The power of PUSCH can reflect the interference of the transmission of this PUSCH on the transmission of other PUSCHs. When the difference or ratio of the PUSCH power between two PUSCHs is large, it means that the transmission of the PUSCH with higher power has greater interference with the PUSCH with lower power. In this case, switching to sending only one PUSCH without scheduling, for example, only sending the PUSCH with higher power, or only sending the PUSCH with lower power, is beneficial to improving transmission performance.

[0205] For example, the power of the first PUSCH is P11 and the power of the second PUSCH is P22. The terminal device can switch to sending only one unscheduled PUSCH, for example, only sending the first PUSCH or the second PUSCH, when the absolute value of the difference between P11 and P22 is greater than or equal to the first threshold, or when the ratio of P11 to P22 is greater than or equal to the first threshold, or when the ratio of P22 to P11 is greater than or equal to the first threshold.

[0206] In some embodiments, the first threshold is predefined or configured by the network device.

[0207] The difference in the timing advances (TAs) of multiple PUSCHs can reflect the timing synchronization between the multiple PUSCH transmissions. If the difference is large, for example, if it exceeds the length of the cyclic prefix (CP), performance loss may occur. In this case, the terminal device can switch to sending only one unscheduled PUSCH, for example, only sending PUSCHs with a larger timer advance, or only sending PUSCHs with a smaller timing advance, which is beneficial to improving transmission performance.

[0208] For example, the TA of the first PUSCH is TA1 and the TA of the second PUSCH is TA2. When the difference between TA1 and TA2 exceeds the second threshold or the difference between TA2 and TA1 exceeds the second threshold, the terminal device switches to sending only one unscheduled PUSCH, for example, only sending the first PUSCH or the second PUSCH.

[0209] In some embodiments, the second threshold is predefined or configured by the network device.

[0210] The length of time that multiple PUSCHs overlap in the time domain can refer to the number of overlapping symbols, for example. The longer the time that multiple PUSCHs overlap in the time domain, the greater the mutual interference. When the length of time that the multiple PUSCHs overlap is long, the terminal device switches to sending only one unscheduled PUSCH, for example, only sending the first PUSCH or the second PUSCH, which is beneficial to improving transmission performance.

[0211] For example, as shown in FIG4 , when the number of symbols overlapping between the first PUSCH and the second PUSCH is greater than a third threshold, the system switches to sending only one PUSCH, for example, sending only the first PUSCH or sending only the second PUSCH.

[0212] In some embodiments, the third threshold is predefined or configured by the network device.

[0213] When the interference between multiple unscheduled PUSCHs is large, the terminal device can switch to sending only one PUSCH, for example, sending only the first PUSCH or only the second PUSCH, which is beneficial to improving transmission performance.

[0214] The greater interference between PUSCHs here may refer to a greater interference intensity caused by the transmission of one PUSCH to the transmission of another PUSCH, or it may refer to a greater intensity of interference relative to the intensity of PUSCH transmission, for example, a greater difference between the intensity of interference and the intensity of PUSCH, or a greater ratio of the intensity of interference to the intensity of PUSCH.

[0215] In some embodiments, the interference of the first PUSCH on the second PUSCH is determined according to the SRS corresponding to the first PUSCH, or according to the signal quality and beam gain of the first PUSCH.

[0216] In some embodiments, the interference of the second PUSCH on the first PUSCH is determined according to the SRS corresponding to the second PUSCH, or according to the signal quality and beam gain of the second PUSCH.

[0217] In some embodiments, the signal quality of the PUSCH may include, but is not limited to, at least one of the following:

[0218] Reference Signal Receiving Power (RSRP), Reference Signal Receiving Quality (RSRQ), Signal to Interference plus Noise Ratio (SINR), Received Signal Strength Indication (RSSI).

[0219] For example, as shown in Figure 5, the power of the first PUSCH is P11, the power of the second PUSCH is P22, the interference of the first PUSCH to the second PUSCH is P12, and the interference of the second PUSCH to the first PUSCH is P21. The terminal device can switch to sending only one PUSCH, for example, only sending the first PUSCH or only sending the second PUSCH, when P12 is greater than the sixth threshold or P21 is greater than the sixth threshold, or P22 / P12 (or P22-P12) is less than or equal to the fifth threshold, or P11 / P21 (or P11-P21) is less than or equal to the fourth threshold.

[0220] In some embodiments, the fourth threshold is predefined or configured by the network device.

[0221] In some embodiments, the fifth threshold is predefined or configured by the network device.

[0222] In some embodiments, the sixth threshold is predefined or configured by the network device.

[0223] The signal quality of PUSCH can also reflect the degree of interference of the transmission of PUSCH on the transmission of other PUSCHs. A large difference in the signal quality of two PUSCHs indicates that the transmission of one PUSCH interferes more with the transmission of another PUSCH. Therefore, when the difference or ratio of the signal quality of the two PUSCHs is large, switching to sending only one PUSCH, for example, sending only the first PUSCH or only the second PUSCH, is beneficial to improving transmission performance.

[0224] For example, when the difference or ratio of the signal quality of the first PUSCH and the signal quality of the second PUSCH is greater than or equal to the seventh threshold, or when the difference or ratio of the signal quality of the second PUSCH and the signal quality of the first PUSCH is greater than or equal to the seventh threshold, switching to sending only the first PUSCH or sending only the second PUSCH is beneficial to improving transmission performance.

[0225] In some embodiments, the seventh threshold is predefined or configured by the network device.

[0226] In summary, in an embodiment of the present application, the terminal device can send one or more scheduling-free PUSCHs to the network device, wherein the terminal device can use different spatial parameters to send the multiple scheduling-free PUSCHs.

[0227] Furthermore, when the terminal device sends multiple scheduling-free PUSCHs, the multiple PUSCHs may be configured through the same high-level parameters, or may be configured through different high-level parameters.
