[0030] Figure 2 It is a schematic flowchart of a method for transmitting an uplink channel with multiple beams provided by an embodiment of the present invention. The method is applied to a terminal device, and the method can be as follows.

[0031] Step 210, receive configuration information, where the configuration information includes multiple uplink beam information for the uplink channel; the multiple uplink beam information has an associated relationship with the relevant parameters of the uplink channel.

[0032] The network-side device configures multiple uplink beam information for the terminal device for the uplink channel.

[0033] The following will respectively introduce in detail two aspects: the network-side device configures multiple uplink beam information for the physical uplink shared channel (PUSCH) and the network-side device configures multiple uplink beam information for the physical uplink control channel (PUCCH).

[0034] The first aspect: The network-side device configures multiple uplink beam information for the PUSCH.

[0035] In the embodiments of the present invention, receiving the configuration information includes:

[0036] Receive downlink control information (DCI), where the DCI is used to indicate configuration information.

[0037] The network device indicates configuration information to the terminal device through the DCI for scheduling PUSCH, and the configuration information is used to configure multiple uplink beam information for PUSCH.

[0038] Specifically, the DCI includes at least one sounding reference signal resource indicator (SRI) signaling field;

[0039] The ways for the DCI to indicate configuration information include at least one of the following:

[0040] One SRI signaling field indicates multiple resource indication information, where each resource indication information in the multiple resource indication information indicates one uplink beam information;

[0041] Multiple SRI signaling fields indicate multiple resource indication information, where each SRI signaling field in the multiple SRI signaling fields indicates at least one resource indication information, and each resource indication information in the at least one resource indication information indicates one uplink beam information.

[0042] Among them, the resource indication information includes at least one of the following:

[0043] Channel state information reference signal resource indicator (CRI), synchronization signal block resource indicator (SSBRI), SRI.

[0044] In an embodiment, the DCI includes one SRI signaling field. Regardless of the number of bits of the SRI signaling field, the DCI uses the SRI signaling field to indicate multiple resource indication information, where each resource indication information in the multiple resource indication information indicates one uplink beam information.

[0045] For example, a DCI1 for scheduling a PUSCH by a network-side device includes an SRI signaling field. The number of bits in the SRI signaling field is 3 bits (bit). Then, the SRI signaling field can have 8 SRI signaling field values (000 to 111), which respectively correspond to 8 SRI code points (codepoint). The network-side device has pre-determined multiple resource indication information corresponding to each SRI codepoint: SRI codepoint 000 corresponds to two resource indication information: CRI1 and CRI2, SRI codepoint 001 corresponds to two resource indication information: CRI3 and SSBRI2, and so on.

[0046] After the terminal device receives DCI1, if the SRI codepoint of the SRI signaling field in DCI1 is 001, the terminal device can determine that the network-side device has configured two uplink beam information for the PUSCH, which are respectively: the uplink beam information indicated by CRI3 and the uplink beam information indicated by SSBRI2.

[0047] In another embodiment, a DCI includes an SRI signaling field. The SRI signaling field can be divided into multiple parts. The DCI uses each of the multiple parts to respectively indicate at least one resource indication information, where each resource indication information in the at least one resource indication information indicates an uplink beam information.

[0048] For example, a DCI2 for scheduling a PUSCH by a network-side device includes an SRI signaling field. The number of bits in the SRI signaling field is 9 bit. The network-side device divides the SRI signaling field into three parts: the first part is the first three bits, the second part is the middle three bits, and the third part is the last three bits.

[0049] Each of the three parts of the SRI signaling field can have 8 SRI signaling field values (000 to 111), which respectively correspond to 8 SRI codepoint. The SRI signaling field values of the three parts of the SRI signaling field together constitute an SRI signaling field of the SRI signaling field, and the one SRI signaling field corresponds to one SRI codepoint.

[0050] The network-side device has pre-determined multiple resource indication information corresponding to each SRI codepoint in each part of the three parts of the SRI signaling field.

[0051] The first part of the SRI signaling field: SRI codepoint 000 corresponds to two resource indication information: CRI1 and CRI2, SRI codepoint 001 corresponds to one resource indication information: SSBRI2, and so on;

[0052] The second part of the SRI signaling field: SRI codepoint 100 corresponds to two resource indication messages: CRI3 and CRI4, SRI codepoint 111 corresponds to two resource indication messages: SSBRI1 and SSBRI3, etc.;

[0053] The third part of the SRI signaling field: SRI codepoint 101 corresponds to two resource indication messages SRI1 and SRI2, SRI codepoint 110 corresponds to two resource indication messages: SRI3 and SRI4, etc.

[0054] After the terminal device receives DCI2, if the SRI codepoint of the SRI signaling field in DCI2 is 001111101, that is, the SRI codepoint of the first part of the SRI signaling field is 001, the SRI codepoint of the second part is 111, and the SRI codepoint of the third part is 101.

[0055] Then the terminal device can determine that the network side device has configured five uplink beam messages for the PUSCH, which are: the uplink beam message indicated by SSBRI2, the uplink beam message indicated by SSBRI1, the uplink beam message indicated by SSBRI3, the uplink beam message indicated by SRI1, and the uplink beam message indicated by SRI2.

[0056] In another embodiment, the DCI includes multiple SRI signaling fields, and the DCI uses each SRI signaling field in the multiple SRI signaling fields to respectively indicate at least one resource indication message, where each resource indication message in the at least one resource indication message indicates an uplink beam message.

[0057] For example, the DCI3 for the network side device to schedule the PUSCH includes three SRI signaling fields: the first SRI signaling field, the second SRI signaling field, and the third SRI signaling field. The number of bits of each SRI signaling field is 3 bits (that is, the DCI2 includes a 9-bit SRI signaling field), then each SRI signaling field can have 8 SRI signaling field values (000 to 111), respectively corresponding to 8 SRI codepoints.

[0058] The network side device has pre-determined at least one resource indication message corresponding to each SRI codepoint in each SRI signaling field.

[0059] In the first SRI signaling field, SRI codepoint 000 corresponds to two resource indication messages: CRI1 and CRI2, SRI codepoint 001 corresponds to one resource indication message: SRI2, etc.;

[0060] In the second SRI signaling field, SRI codepoint 100 corresponds to two resource indication messages: CRI3 and SSBRI1, SRI codepoint 111 corresponds to two resource indication messages: SRI1 and SSBRI2, and so on;

[0061] In the third SRI signaling field, SRI codepoint 101 corresponds to one resource indication message: SRI3, SRI codepoint 110 corresponds to two resource indication messages: CRI4 and SSBRI3, and so on.

[0062] After the terminal device receives DCI3, if the SRI codepoint in the first SRI signaling field in DCI3 is 000, the SRI codepoint in the second SRI signaling field is 111, and the SRI codepoint in the third SRI signaling field is 101, then the terminal device can determine that the network side device has configured five uplink beam messages for the PUSCH, which are respectively: the uplink beam message indicated by CRI1, the uplink beam message indicated by CRI2, the uplink beam message indicated by SRI1, the uplink beam message indicated by SSBRI2, and the uplink beam message indicated by SRI3.

[0063] In the embodiment of the present invention, before receiving DCI, it further includes:

[0064] Receiving a radio resource control (RRC) signaling, where the RRC signaling is used to configure the spatial relation information of the PUSCH, or is used to configure the spatial relation of the sounding reference signal (SRS) resource.

[0065] The network side device configures the spatial relation of the PUSCH or configures the spatial relation of the SRS resource for the terminal device through the RRC signaling, and further configures multiple uplink beam messages for the PUSCH in the DCI scheduling the PUSCH, where the multiple uplink beam messages configured for the PUSCH in the DCI are determined according to the spatial relation of the PUSCH configured by the RRC signaling, or are determined according to the spatial relation of the SRS resource configured by the RRC signaling.

[0066] In the embodiment of the present invention, the manner in which the RRC signaling configures the spatial relation of the PUSCH includes at least one of the following:

[0067] The RRC signaling includes a Physical Uplink Shared Channel Spatial Relation Information (PUSCH-Spatial RelationInfo), and the PUSCH-Spatial Relation Info includes multiple resource indication information;

[0068] The RRC signaling includes multiple PUSCH-Spatial Relation Info, and each PUSCH-Spatial Relation Info in the multiple PUSCH-Spatial Relation Info includes at least one resource indication information.

[0069] In an embodiment, the terminal device receives RRC signaling sent by the network side device. The RRC signaling includes a PUSCH-Spatial Relation Info, and the PUSCH-Spatial Relation Info includes three resource indication information: CRI1, SRI2, and SSBRI2.

[0070] When the network side device schedules the PUSCH subsequently, it can indicate the PUSCH-Spatial Relation Info through the DCI for scheduling the PUSCH, so as to configure three uplink beam information for the PUSCH, namely: the uplink beam information indicated by CRI1, the uplink beam information indicated by SRI2, and the uplink beam information indicated by SSBRI2.

[0071] In another embodiment, the terminal device receives RRC signaling sent by the network side device. The RRC signaling includes two PUSCH-Spatial Relation Info: the first PUSCH-Spatial Relation Info and the second PUSCH-Spatial Relation Info. Among them, the first PUSCH-Spatial Relation Info includes two resource indication information: SRI1 and SSBRI1, and the second PUSCH-Spatial Relation Info includes three resource indication information: CRI1, SRI2, and SSBRI2.

[0072] When the network - side device schedules the PUSCH subsequently, it can indicate the first PUSCH - Spatial Relation Info and the second PUSCH - Spatial Relation Info through the DCI for scheduling the PUSCH, so as to configure five uplink beam information for the PUSCH, which are respectively: the uplink beam information indicated by SRI1, the uplink beam information indicated by SSBRI1, the uplink beam information indicated by CRI1, the uplink beam information indicated by SRI2, and the uplink beam information indicated by SSBRI2.

[0073] In the embodiments of the present invention, the ways of configuring the Spatial Relation of the SRS resource by RRC signaling include at least one of the following:

[0074] The RRC signaling configures a sounding reference signal spatial relation information (SRS - SpatialRelation Info) for each SRS resource, where the SRS - Spatial Relation Info includes multiple resource indication information.

[0075] The RRC signaling configures multiple SRS - Spatial Relation Info for each SRS resource, where each SRS - Spatial Relation Info in the multiple SRS - Spatial Relation Info includes at least one resource indication information.

[0076] In an embodiment, the network - side device configures the SRS resource for the terminal device. The terminal device receives the RRC signaling sent by the network - side device. The RRC signaling configures an SRS - Spatial Relation Info for each SRS resource, and the SRS - Spatial Relation Info includes multiple resource indication information.

[0077] For example, the network - side device configures an SRS - Spatial RelationInfo for the first SRS resource through the RRC signaling, and the SRS - Spatial Relation Info includes two resource indication information: CRI1 and CRI2.

[0078] When the network - side device schedules the PUSCH subsequently, it can indicate the first SRS resource through the DCI for scheduling the PUSCH, and thus determine that the network - side device configures two uplink beam information for the PUSCH according to the SRS - Spatial Relation Info of the first SRS resource configured by the RRC signaling for the first SRS resource, which are respectively: the uplink beam information indicated by CRI1 and the uplink beam information indicated by CRI2.

[0079] In another embodiment, the network-side device configures SRS resources for the terminal device. The terminal device receives the RRC signaling sent by the network-side device, and the RRC signaling configures at least one SRS-Spatial Relation Info for each SRS resource, and each SRS-Spatial Relation Info in the at least one SRS-Spatial Relation Info includes at least one resource indication information.

[0080] For example, the network-side device configures two SRS-Spatial RelationInfos for the first SRS resource through RRC signaling: the first SRS-Spatial Relation Info and the second SRS-Spatial Relation Info, where the first SRS-Spatial Relation Info includes two resource indication information: CRI1 and CRI2, and the second SRS-Spatial Relation Info includes one resource indication information: SRI1;

[0081] The RRC signaling configures two SRS-Spatial Relation Infos for the second SRS resource: the third SRS-Spatial Relation Info and the fourth SRS-Spatial Relation Info, where the third SRS-Spatial Relation Info includes two resource indication information: SSBRI1 and SSBRI2, and the fourth SRS-Spatial Relation Info includes two resource indication information: SRI2 and SRI3.

[0082] When the network - side device schedules the PUSCH subsequently, it can indicate the first SRS resource and the second SRS resource through the DCI for scheduling the PUSCH. Thus, according to the first SRS - Spatial Relation Info and the second SRS - Spatial Relation Info configured for the first SRS resource according to the RRC signaling, and the third SRS - Spatial Relation Info and the fourth SRS - Spatial Relation Info configured for the second SRS resource according to the RRC signaling, it is determined that the network - side device configures seven uplink beam information for the PUSCH, which are respectively: the uplink beam information indicated by CRI1, the uplink beam information indicated by CRI2, the uplink beam information indicated by SRI1, the uplink beam information indicated by SSBRI1, the uplink beam information indicated by SSBRI2, the uplink beam information indicated by SRI2, and the uplink beam information indicated by SRI3.

[0083] Second aspect: The network - side device configures multiple uplink beam information for the PUCCH.

[0084] The ways for the network - side device to configure multiple uplink beam information for the PUCCH include at least two of the following.

[0085] The first way:

[0086] In the embodiments of the present invention, receiving configuration information includes:

[0087] Receiving DCI, where the DCI is used to indicate the configuration information.

[0088] The network - side device indicates the configuration information to the terminal device through the DCI, and the configuration information is used to configure multiple uplink beam information for the PUCCH.

[0089] Specifically, the DCI includes at least one signaling field;

[0090] The ways for the DCI to indicate the configuration information include at least one of the following:

[0091] One signaling field indicates one Physical Uplink Control Channel Spatial Relation Information (PUCCH - Spatial Relation Info), where the PUCCH - Spatial Relation Info indicates multiple resource indication information, and each resource indication information in the multiple resource indication information indicates one uplink beam information;

[0092] At least one signaling field indicates multiple PUCCH-Spatial Relation Info, where each PUCCH-Spatial Relation Info among the multiple PUCCH-Spatial Relation Info indicates at least one resource indication information, and each resource indication information among the at least one resource indication information indicates one uplink beam information.

[0093] The network device configures multiple uplink beam information for PUCCH through DCI.

[0094] In one embodiment, the DCI in which the network device configures multiple uplink beam information for PUCCH includes a signaling field. Regardless of the number of bits of the signaling field, the DCI uses this signaling field to indicate one PUCCH-Spatial Relation Info, where this PUCCH-Spatial Relation Info indicates multiple resource indication information, and each resource indication information among the multiple resource indication information indicates one uplink beam information.

[0095] For example, DCI1 in which the network device configures multiple uplink beam information for PUCCH includes a signaling field, and the number of bits of this signaling field is 3 bits. Then this signaling field can have 8 signaling field values (000 to 111), corresponding to 8 code points respectively. The network device has pre-determined one PUCCH-Spatial Relation Info corresponding to each code point, and multiple resource indication information indicated by each PUCCH-Spatial Relation Info: code point 000 corresponds to the first PUCCH-Spatial Relation Info, and the first PUCCH-Spatial Relation Info indicates two resource indication information: CRI1 and CRI2; code point 001 corresponds to the second PUCCH-Spatial Relation Info, and the second PUCCH-Spatial Relation Info indicates two resource indication information: SSBRI1 and SRI1, etc.

[0096] After the terminal device receives this DCI1, if the code point of this signaling field in DCI1 is 000, the terminal device can determine, according to the first PUCCH-Spatial Relation Info indicated by DCI, that the network device has configured two uplink beam information for PUCCH, which are respectively: the uplink beam information indicated by CRI1 and the uplink beam information indicated by CRI2.

[0097] In another embodiment, the DCI in which the network-side device configures multiple uplink beam information for the PUCCH includes multiple signaling domains, and the DCI uses at least one of the multiple signaling domains to indicate multiple PUCCH-Spatial Relation Info. Each PUCCH-Spatial Relation Info in the multiple PUCCH-Spatial Relation Info indicates at least one resource indication information, and each resource indication information in the at least one resource indication information indicates one uplink beam information.

[0098] For example, the DCI2 in which the network-side device configures multiple uplink beam information for the PUCCH includes one signaling domain, and the number of bits of this signaling domain is 3 bits. Then this signaling domain can have 8 signaling domain values (000 to 111), corresponding to 8 codepoints respectively. The network-side device has pre-determined multiple PUCCH-Spatial Relation Info corresponding to each codepoint, and multiple resource indication information indicated by each PUCCH-Spatial Relation Info: codepoint 000 corresponds to the first PUCCH-Spatial Relation Info and the second PUCCH-Spatial Relation Info. Among them, the first PUCCH-Spatial Relation Info indicates one resource indication information: CRI1, and the second PUCCH-Spatial Relation Info indicates one resource indication information: CRI2; codepoint 001 corresponds to the third PUCCH-Spatial Relation Info and the fourth PUCCH-Spatial Relation Info. Among them, the third PUCCH-Spatial Relation Info indicates two resource indication information: SSBRI1 and SRI1, and the fourth PUCCH-Spatial Relation Info indicates two resource indication information: SSBRI2 and SRI3, etc.

[0099] After the terminal device receives the DCI2, if the codepoint of this signaling domain in the DCI2 is 001, then the terminal device can determine that the network-side device has configured four uplink beam information for the PUCCH according to the third PUCCH-Spatial Relation Info and the fourth PUCCH-Spatial Relation Info indicated by the DCI2, which are respectively: the uplink beam information indicated by SSBRI1, the uplink beam information indicated by SRI1, the uplink beam information indicated by SSBRI2, and the uplink beam information indicated by SRI3.

[0100] For example, in DCI 3 in which the network - side device configures multiple uplink beam information for PUCCH, it includes two signaling fields: the first signaling field and the second signaling field. The number of bits of each signaling field is 3 bits (that is, DCI 2 includes a 6 - bit signaling field), so each signaling field can have 8 signaling field values (000 to 111), respectively corresponding to 8 codepoints.

[0101] The network - side device has pre - determined multiple PUCCH - Spatial Relation Info corresponding to each codepoint in each signaling field, and multiple resource indication information indicated by each PUCCH - Spatial Relation Info among multiple PUCCH - Spatial Relation Info corresponding to each codepoint in each signaling field.

[0102] In the first signaling field, codepoint 000 corresponds to two PUCCH - Spatial Relation Info: the first PUCCH - Spatial Relation Info and the second PUCCH - Spatial Relation Info. Among them, the first PUCCH - Spatial Relation Info indicates a resource indication information CRI1, and the second PUCCH - Spatial Relation Info indicates a resource indication information CRI2; codepoint 001 corresponds to two PUCCH - Spatial Relation Info: the third PUCCH - Spatial Relation Info and the fourth PUCCH - Spatial Relation Info. Among them, the third PUCCH - Spatial Relation Info indicates two resource indication information: SSBRI1 and SRI1, and the fourth PUCCH - Spatial Relation Info indicates a resource indication information: SSBRI2, etc.

[0103] In the second signaling field, codepoint 100 corresponds to two PUCCH-Spatial Relation Info: the fifth PUCCH-Spatial Relation Info and the sixth PUCCH-Spatial Relation Info. Among them, the fifth PUCCH-Spatial Relation Info indicates a resource indication information CRI3, and the second PUCCH-Spatial Relation Info indicates a resource indication information CRI4; codepoint 111 corresponds to two PUCCH-Spatial Relation Info: the seventh PUCCH-Spatial Relation Info and the eighth PUCCH-Spatial Relation Info. Among them, the seventh PUCCH-Spatial Relation Info indicates two resource indication information: SSBRI3 and SRI2, and the eighth PUCCH-Spatial Relation Info indicates a resource indication information: SRI3, etc.

[0104] After the terminal device receives the DCI3, if the codepoint of the first signaling field in the DCI3 is 000 and the codepoint of the second signaling field is 111, the terminal device can determine that the network side device has configured five uplink beam information for the PUCCH according to the first PUCCH-Spatial Relation Info, the second PUCCH-Spatial Relation Info, the seventh PUCCH-Spatial Relation Info, and the eighth PUCCH-Spatial Relation Info indicated by the DCI3, which are respectively: the uplink beam information indicated by CRI1, the uplink beam information indicated by CRI2, the uplink beam information indicated by SSBRI3, the uplink beam information indicated by SRI2, and the uplink beam information indicated by SRI3.

[0105] The second type:

[0106] In the embodiment of the present invention, receiving configuration information includes:

[0107] Receiving a high-layer signaling, where the high-layer signaling is used to indicate the configuration information;

[0108] The high-layer signaling includes at least one of the following: RRC signaling, Medium Access Control Control Element (MAC CE) signaling.

[0109] Specifically, the ways for the high-layer signaling to indicate the configuration information include at least one of the following:

[0110] One PUCCH-Spatial Relation Info indicates multiple resource indication information, where each resource indication information in the multiple resource indication information indicates one uplink beam information;

[0111] Multiple PUCCH-Spatial Relation Info indicate multiple resource indication information, where each PUCCH-Spatial Relation Info in the multiple PUCCH-Spatial Relation-Info indicates at least one resource indication information, and each resource indication information in the at least one resource indication information indicates one uplink beam information.

[0112] The network-side device configures multiple uplink beam information for the PUCCH through high-layer signaling (RRC signaling, MAC CE signaling).

[0113] In an embodiment, the terminal device receives the RRC signaling sent by the network-side device. The RRC signaling includes a PUCCH-Spatial Relation Info, and the PUCCH-Spatial Relation Info indicates two resource indication information: SRI1 and SSBRI1. Therefore, the terminal device can determine that the network-side device configures two uplink beam information for the PUCCH through the RRC signaling, which are respectively: the uplink beam information indicated by SRI1 and the uplink beam information indicated by SSBRI1.

[0114] In another embodiment, the terminal device receives the RRC signaling sent by the network-side device. The RRC signaling includes two PUSCH-Spatial Relation Info: the first PUSCH-Spatial Relation Info and the second PUSCH-Spatial Relation Info. Among them, the first PUSCH-Spatial Relation Info indicates one resource indication information: SRI1, and the second PUSCH-Spatial Relation Info indicates three resource indication information: CRI1, SRI2, and SSBRI2. Therefore, the terminal device can determine that the network-side device configures four uplink beam information for the PUCCH through the RRC signaling, which are respectively: the uplink beam information indicated by SRI1, the uplink beam information indicated by CRI1, the uplink beam information indicated by SRI2, and the uplink beam information indicated by SSBRI2.

[0115] In the embodiments of the present invention, the determination method of the association relationship between multiple uplink beam information and the relevant parameters of the uplink channel includes at least one of the following:

Then, the terminal device uses multiple uplink beam information to send PUSCH or PUCCH in sequence according to the preset beam usage order, so that the network - side device receives PUSCH or PUCCH using multiple uplink beam information in sequence according to the preset beam usage order.

[0355] The technical solution described in the embodiments of the present invention configures multiple uplink beam information for the uplink channel through configuration information.
