[0063] 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.

[0064] 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.

[0066] To facilitate understanding of the technical solutions of the embodiments of the present application, the relevant technologies of the embodiments of the present application are described below. The following relevant technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the protection scope of the embodiments of the present application.

[0067] 1. Multi-antenna (panel) / TRP transmission:

[0068] If the terminal is configured with multiple antennas (panels) or antenna ports and supports simultaneous transmission of uplink information to multiple TRPs on multiple antennas or antenna ports, multiple uplink information can be sent on multiple panels at the same time to improve the uplink spectrum efficiency. Figure 1 is a schematic diagram of the multi-antenna / TRP transmission scenario. As shown in Figure 1, the uplink transmission of multiple antennas / TRPs can be scheduled through a single downlink control information (DCI) or through multiple DCIs. The multiple PUSCHs sent by the UE are in a unified transmission configuration indicator (TCI) scenario. The multiple PUSCHs are associated with different TCI states and may not overlap, partially overlap, or completely overlap in the time domain.

[0069] The backhaul connection between TRPs can be ideal or non-ideal. In an ideal backhaul, TRPs can exchange information quickly and dynamically. In a non-ideal backhaul, due to the large delay, TRPs can only exchange information quasi-statically.

[0070] 2. Processing of multiple PUCCHs overlapping in the time domain, or PUCCH and PUSCH overlapping in the time domain:

[0071] In a multi-TRP scenario, in order to remove restrictions on system scheduling flexibility, multiple PUCCHs associated with different spatial information may be allowed to be transmitted simultaneously, or PUCCHs and PUSCHs associated with different spatial information may be allowed to be transmitted simultaneously. Figure 2A is a schematic diagram of a scenario in which multiple PUCCHs are transmitted simultaneously. As shown in Figure 2A, a terminal device transmits PUCCHs to different TRPs simultaneously through different antennas (panels) / beams, where PUCCH#1 is associated with antenna 1 / beam 1, and PUCCH#1 is associated with antenna 2 / beam 2. Figure 2B is a schematic diagram of a scenario in which PUCCH and PUSCH are transmitted simultaneously. As shown in Figure 2B, a terminal device transmits PUCCH and PUSCH to different TRPs simultaneously through different antennas (panels) / beams, where PUCCH is associated with antenna 1 / beam 1, and PUSCH is associated with antenna 2 / beam 2.

[0072] The aforementioned "simultaneous transmission" may refer to transmission in a time domain overlapping manner or within a first time unit; wherein time domain overlap may include complete overlap or partial overlap. For example, when a terminal device transmits PUCCH and PUSCH simultaneously, this may mean that the PUCCH and PUSCH transmitted by the terminal device completely overlap or partially overlap in the time domain, or that the terminal device transmits PUCCH and PUSCH within a first time unit. The first time unit may be a pre-set time period or a fixed-length time period.

[0073] FIG3 is a schematic flow chart of a communication method 300 according to an embodiment of the present application. The method may optionally be applied to the system shown in FIG1 , FIG2A , or FIG2B , but is not limited thereto. The method includes at least part of the following contents.

[0074] S310. The terminal device determines a multiplexing mode according to at least one of the configuration information of the first higher layer parameter and the configuration information of the first transmission mode.

[0075] S320. The terminal device transmits UCI carried by one or more PUCCHs according to the multiplexing method.

[0076] The multiplexing method may include: whether to use PUSCH to transmit UCI carried by one or more PUCCHs, which PUSCH(s) to use to transmit UCI carried by which PUCCH(s), and how to handle PUCCHs that are not transmitted by PUSCH. Accordingly, the terminal device may transmit UCI carried by one or more PUCCHs according to the multiplexing method. When the UCI carried by one or more PUCCHs is transmitted by PUSCH, the one or more PUCCHs may not be sent.

[0077] The communication method proposed in the embodiment of the present application can solve the problem of multiplexing UCI when multiple PUCCHs are sent simultaneously, or when PUCCH and PUSCH are sent simultaneously, by determining the multiplexing mode based on the configuration information of the first high-level parameter and the configuration information of the first transmission mode, and transmitting the UCI carried by one or more PUCCHs according to the multiplexing mode. Among them, the terminal device can determine the corresponding multiplexing mode based on the configuration information of the first high-level parameter and / or the configuration information of the first transmission mode; for example, the multiplexing mode can be any one of the first mode, the second mode, the third mode, the fourth mode, the fifth mode, and the sixth mode. The above-mentioned various modes are described in detail below.

[0078] In some implementations, the configuration information of the first transmission mode may include:

[0079] The terminal device is configured to use the first transmission mode; or,

[0080] The terminal device is not configured as the first transmission mode.

[0081] The first transmission mode may include: PUCCH and PUSCH associated with different spatial information can be sent simultaneously.

[0082] In some implementations, the configuration information of the first higher layer parameter may include a first value or a second value.

[0083] In one example, the first high-level parameter includes: Hybrid Automatic Repeat ReQuest (HARQ) feedback mode configuration (ackNackFeedbackMode); the configuration information of the HARQ feedback mode configuration may include: separate feedback (separate) or joint feedback (joint), where separate feedback (separate) can be the first value and joint feedback (joint) can be the second value.

[0084] In some embodiments, the terminal device determines that one or more PUCCHs and one or more PUSCHs overlap in the time domain or are sent within a first time unit; wherein,

[0085] The one or more PUCCHs include one or more PUCCHs transmitted based on the same or different spatial information;

[0086] The one or more PUSCHs include one or more PUSCHs transmitted based on the same or different spatial information.

[0087] In some embodiments, the plurality of PUCCHs includes one or more of the following:

[0088] Multiple PUCCHs scheduled by a single DCI and transmitted in a single frequency network (SFN);

[0089] Multiple PUCCHs scheduled by a single DCI and transmitted in a space division multiplexing (SDM) manner;

[0090] Multiple PUCCHs scheduled by multiple DCIs.

[0091] In addition, in some implementations, the multiple PUCCHs may include: multiple PUCCHs associated with different spatial information, or multiple PUCCHs associated with the same spatial information.

[0092] In some embodiments, the plurality of PUSCHs includes one or more of the following:

[0093] Multiple PUSCHs scheduled by multiple DCIs;

[0094] One or more PUSCHs scheduled by a single DCI;

[0095] One or more configured grants PUSCH.

[0096] Specifically, the terminal device determines that the multiple PUSCHs to be transmitted may include multiple PUSCHs scheduled by DCI, or include multiple Configured grant PUSCHs, or include at least one PUSCH scheduled by DCI and at least one Configured grant PUSCH. Among them, when the terminal device determines that there are multiple PUSCHs scheduled by DCI among the multiple PUSCHs to be transmitted, the multiple PUSCHs may be scheduled by a single DCI (that is, the multiple PUSCHs are scheduled by the same DCI) or by multiple DCIs (that is, the multiple PUSCHs are scheduled by multiple different DCIs).

[0097] The one or more configured PUSCH grants may be type 1 configured PUSCH grants and / or type 2 configured PUSCH grants. The time domain resources, frequency domain resources, spatial information, etc. of the type 1 configured PUSCH grants may be configured via RRC signaling, and transmission may be triggered via DCI signaling. The time domain resources, frequency domain resources, spatial information, etc. of the type 2 configured PUSCH grants may be configured via RRC signaling.

[0098] In addition, in some implementations, the multiple PUSCHs may include: multiple PUSCHs associated with different spatial information, or multiple PUSCHs associated with the same spatial information.

[0099] When the terminal device determines that one or more PUCCHs overlap with one or more PUSCHs in the time domain or are sent within the first time unit, the terminal device can determine the multiplexing method of the UCI carried by the one or more PUCCHs based on at least one of the configuration information of the first high-level parameters and the configuration information of the first transmission method, and transmit according to the multiplexing method.

[0100] Specifically, the above situation can be divided into the following three situations:

[0101] Case 1: The terminal device determines that one PUCCH and multiple PUSCHs overlap in the time domain, or one PUCCH and multiple PUSCHs are sent within the first time unit.

[0102] Case 2: The terminal device determines that multiple PUCCHs and one PUSCH overlap in the time domain, or multiple PUCCHs and one PUSCH are sent within the first time unit.

[0103] Case 3: The terminal device determines that multiple PUCCHs and multiple PUSCHs overlap in the time domain, or multiple PUCCHs and multiple PUSCHs are sent within the first time unit.

[0104] In the above three cases, the terminal device determines the multiplexing mode of the UCI carried by the PUCCH as follows:

[0105] (1) Case 1: The terminal device determines that one PUCCH and multiple PUSCHs overlap in the time domain, or one PUCCH and multiple PUSCHs are sent within the first time unit. The overlap in the time domain may include complete overlap or partial overlap.

[0106] (1) In case 1, the terminal device determines the multiplexing mode according to at least one of the configuration information of the first higher layer parameter and the configuration information of the first transmission mode, which may include:

[0107] When the terminal device is configured as the first transmission mode and the terminal device is configured for PUSCH transmission scheduled by multiple DCIs (enableSTx2PofmDCI is configured), determining the multiplexing mode is: multiplexing the UCI carried by the PUCCH into the first PUSCH;

[0108] The spatial information associated with the PUCCH is the same as the spatial information associated with the first PUSCH, and the multiple PUSCHs include the first PUSCH.

[0109] The above-mentioned multiplexing method can be called the first method.

[0110] According to the first method, the terminal device can transmit the multiple PUSCHs, the first PUSCH among the multiple PUSCHs transmits the UCI carried by the PUCCH, and does not transmit the PUCCH.

[0111] For example, when the terminal device determines to transmit PUCCH#1, PUSCH#1, PUSCH#2, and PUSCH#3, and the spatial information associated with PUCCH#1 is the same as the spatial information associated with PUSCH#1, if the terminal device determines that the corresponding multiplexing mode is the first mode based on the configuration information of the first transmission mode, the terminal device transmits PUSCH#1, PUSCH#2, and PUSCH#3, where PUSCH#1 transmits the UCI carried by PUCCH#1, and the terminal device does not transmit PUCCH#1.

[0112] In the first approach, the spatial information may include one or more of the following:

[0113] Joint TCI status;

[0114] Uplink (UL) TCI status;

[0115] Control resource collection group index;

[0116] Sounding Reference Signal (SRS) resource set;

[0117] Reference signals corresponding to spatial relationships;

[0118] Reference signal corresponding to type D quasi-co-located (QCL);

[0119] Antenna panel identification;

[0120] TRP index;

[0121] Beam index.

[0122] In the first approach, the terminal device can simultaneously transmit PUCCH and PUSCH associated with different spatial information, without considering the configuration of the first higher-layer parameter. UCI is directly multiplexed according to the first approach, which simplifies UCI multiplexing. Furthermore, UCI is multiplexed based on spatial information without discarding UCI, ensuring the complete transmission of all information.

[0123] (2) In case 1, the terminal device determines the multiplexing mode according to at least one of the configuration information of the first higher layer parameter and the configuration information of the first transmission mode, which may include:

[0124] When the terminal device is not configured as the first transmission mode and the terminal device is configured for PUSCH transmission with multiple DCI scheduling (enableSTx2PofmDCI is configured), the multiplexing mode is determined as follows:

[0125] If the configuration information of the first high-layer parameter is a first value, multiplexing the UCI carried by the PUCCH into a first PUSCH; wherein the spatial information associated with the PUCCH is the same as the spatial information associated with the first PUSCH, and the multiple PUSCHs include the first PUSCH;

[0126] If the configuration information of the first higher layer parameter is a second value, the UCI carried by the PUCCH is multiplexed into the second PUSCH.

[0127] In one example, the spatial information may include one or more of the following:

[0128] Joint TCI status;

[0129] UL TCI status;

[0130] Control resource collection group index;

[0131] SRS resource collection;

[0132] Reference signals corresponding to spatial relationships;

[0133] Reference signal corresponding to type D QCL;

[0134] Antenna panel identification;

[0135] TRP index;

[0136] Beam index.

[0137] In one example, the second PUSCH may include one or more of the following:

[0138] The PUSCH associated with the first joint TCI state / uplink (UL) TCI state among multiple PUSCHs;

[0139] The PUSCH with the smallest antenna panel identifier or TRP index among multiple PUSCHs; for example, the PUSCH with an antenna panel or TRP index of 0;

[0140] The PUSCH with the smallest SRS resource set index among multiple PUSCHs; for example, the PUSCH with an SRS resource set index of 0;

[0141] The PUSCH with the smallest reference signal resource index or reference signal resource set index associated with multiple PUSCHs; for example, the PUSCH with a reference signal resource index or reference signal resource set index of 0

[0142] The PUSCH with the smallest control resource set (CORESET) group index among multiple PUSCHs; for example, the PUSCH with a CORESET group index of 0;

[0143] The PUSCH that starts sending earliest among multiple PUSCHs;

[0144] The earliest scheduled PUSCH among multiple PUSCHs;

[0145] The PUSCH with the highest modulation and coding scheme (MCS) level among multiple PUSCHs.

[0146] The above multiplexing method can be called the second method.

[0147] According to the second method, the terminal device can transmit the multiple PUSCHs, and the first PUSCH or the second PUSCH among the multiple PUSCHs transmits the UCI carried by the PUCCH, and does not transmit the PUCCH.

[0148] In the second mode, when the terminal device is not configured with the first transmission mode, if the backhaul between multiple TRPs is not ideal, the UCI multiplexing can be simplified directly according to the second mode. In addition, UCI multiplexing based on spatial information can ensure the complete transmission of all information. When the terminal device is not configured with the first transmission mode, if the backhaul between multiple TRPs is ideal, it only needs to be multiplexed into one target PUSCH, which is simpler to implement. The PUSCH with the highest MCS level of the modulation and coding scheme is more reliable as the second PUSCH to carry UCI. The earliest scheduled PUSCH among multiple PUSCHs is used as the second PUSCH, so that UCI can be transmitted as early as possible, shortening the transmission delay.

[0149] (2) Case 2: The terminal device determines that multiple PUCCHs and one PUSCH overlap in the time domain, or multiple PUCCHs and one PUSCH are sent within the first time unit. The overlap in the time domain may include complete overlap or partial overlap.

[0150] (1) In case 2, the terminal device determines the multiplexing mode according to at least one of the configuration information of the first higher layer parameter and the configuration information of the first transmission mode, which may include:

[0151] When the terminal device is configured in the first transmission mode, determining the multiplexing mode is: multiplexing the UCI carried by the first PUCCH into the PUSCH;

[0152] The spatial information associated with the first PUCCH is the same as the spatial information associated with the PUSCH, and the multiple PUCCHs include the first PUCCH.

[0153] The above multiplexing method can be called the third method.

[0154] According to the third method, the terminal device can transmit the PUSCH, which transmits the UCI carried by the first PUCCH. The terminal device also transmits other PUCCHs except the first PUCCH.

[0155] For example, when the terminal device determines to transmit PUCCH#1, PUCCH#2, PUCCH#3, and PUSCH#1, and the spatial information associated with PUCCH#1 is the same as the spatial information associated with PUSCH#1, if the terminal device determines that the corresponding multiplexing mode is the third mode based on the configuration information of the first transmission mode, the terminal device transmits PUSCH#1, PUCCH#2, and PUCCH#3, where PUSCH#1 transmits the UCI carried by PUCCH#1, and the terminal device does not transmit PUCCH#1.

[0156] In the first approach, the spatial information may include one or more of the following:

[0157] Joint TCI status;

[0158] UL TCI status;

[0159] Control resource collection group index;

[0160] SRS resource collection;

[0161] Reference signals corresponding to spatial relationships;

[0162] Reference signal corresponding to type D QCL;

[0163] Antenna panel identification;

[0164] TRP index;

[0165] Beam index.

[0166] (2) Under the second scenario, the terminal device determines the multiplexing mode according to at least one of the configuration information of the first higher layer parameter and the configuration information of the first transmission mode, which may include:

[0167] When the terminal device is not configured for the first transmission mode, if the configuration information of the first higher-layer parameter is the first value, there are at least the following three possibilities:

[0168] The first possibility is that the terminal device does not expect this situation to occur, so the terminal device may determine that this situation is an error case.

[0169] Possibility 2: The terminal device determines that the multiplexing mode is to multiplex the UCI carried by the first PUCCH into the PUSCH, and not transmit other PUCCHs except the first PUCCH among the multiple PUCCHs;

[0170] The spatial information associated with the first PUCCH is the same as the spatial information associated with the PUSCH, and the multiple PUCCHs include the first PUCCH.

[0171] The third possibility: when the priority corresponding to the priority indexes of multiple PUCCHs is higher than the priority corresponding to the priority index of the PUSCH, determine to transmit the multiple PUCCHs and not transmit the PUSCH; when the priority corresponding to the priority indexes of the multiple PUCCHs is lower than or equal to the priority corresponding to the priority index of the PUSCH, multiplex the UCI carried by the first PUCCH into the PUSCH, and do not transmit other PUCCHs except the first PUCCH in the multiple PUCCHs; wherein the spatial information associated with the first PUCCH is the same as the spatial information associated with the PUSCH, and the multiple PUCCHs include the first PUCCH.

[0172] In a case where the terminal device is not configured as the first transmission mode, if the configuration information of the first high-layer parameter is the second value, UCI carried by multiple PUCCHs is multiplexed into the PUSCH.

[0173] The above-mentioned multiplexing method can be called the fourth method.

[0174] In the fourth mode, the terminal device can determine the multiplexing mode according to the physical channel priority, thereby ensuring the transmission of high-priority channels and guaranteeing the integrity of information transmission to a certain extent.

[0175] (3) Case 3: The terminal device determines that multiple PUCCHs and multiple PUSCHs overlap in the time domain, or that multiple PUCCHs and multiple PUSCHs are sent within the first time unit. The overlap in the time domain may include complete overlap or partial overlap.

[0176] In case 3, the multiplexing mode is related to the configuration information of the first higher layer parameter and has nothing to do with the configuration information of the first transmission mode. An example is as follows:

[0177] (1) Under case 3, when the configuration information of the first high-layer parameter is the first value, the multiplexing mode is determined as follows: UCI carried by one or more PUCCHs in the multiple PUCCHs is multiplexed into the first PUSCH corresponding to the PUCCH;

[0178] The spatial information associated with the PUCCH is the same as the spatial information associated with the first PUSCH corresponding to the PUCCH, and the multiple PUSCHs include the first PUSCH.

[0179] In one example, the spatial information may include one or more of the following:

[0180] Joint TCI status;

[0181] UL TCI status;

[0182] Control resource collection group index;

[0183] SRS resource collection;

[0184] Reference signals corresponding to spatial relationships;

[0185] Reference signal corresponding to type D QCL;

[0186] Antenna panel identification;

[0187] TRP index;

[0188] Beam index.

[0189] The above method can be called the fifth method.

[0190] According to the fifth manner, the terminal device uses PUSCH to transmit the UCI carried by the PUCCH corresponding to the PUSCH, instead of transmitting the PUCCH corresponding to the PUSCH.

[0191] For example, when a terminal device determines to simultaneously transmit PUCCH#1, PUCCH#2, PUSCH#1, and PUSCH#2, and the spatial information associated with PUCCH#1 is the same as the spatial information associated with PUSCH#1, and the spatial information associated with PUCCH#2 is the same as the spatial information associated with PUSCH#2, that is, the first PUSCH corresponding to PUCCH#1 is PUSCH#1, and the first PUSCH corresponding to PUCCH#2 is PUSCH#2, when the configuration information of the first high-layer parameter is the first value, the terminal device determines the multiplexing mode as follows: multiplexing the UCI carried by PUCCH#1 into the corresponding PUSCH#1, and multiplexing the UCI carried by PUCCH#2 into the corresponding PUSCH#2. According to this multiplexing mode, the terminal device only transmits PUSCH#1 and PUSCH#2, and does not transmit PUCCH#1 and PUCCH#2.

[0192] The above method can be called the fifth method.

[0193] According to the fifth approach, the terminal device uses the PUSCH to transmit the UCI carried by the PUCCH corresponding to the PUSCH, instead of transmitting the PUCCH corresponding to the PUSCH. Using the fifth approach, the terminal device can multiplex the UCI based on spatial information to ensure complete transmission of all information.

[0194] (2) Under situation 3, when the configuration information of the first high-level parameter is the second value, the terminal device determines the multiplexing mode as follows: multiplexing the UCI carried by one or more PUCCHs in the multiple PUCCHs into the second PUSCH. For example, multiplexing the UCI carried by all PUCCHs in the multiple PUCCHs into the second PUSCH.

[0195] The second PUSCH may include one or more of the following:

[0196] The PUSCH associated with the first joint TCI state / uplink (UL) TCI state among multiple PUSCHs;

[0197] The PUSCH with the smallest antenna panel identifier or TRP index among multiple PUSCHs; for example, the PUSCH with an antenna panel or TRP index of 0;

[0198] The PUSCH with the smallest SRS resource set index among multiple PUSCHs; for example, the PUSCH with an SRS resource set index of 0;

[0199] The PUSCH with the smallest reference signal resource index or reference signal resource set index associated with multiple PUSCHs; for example, the PUSCH with a reference signal resource index or reference signal resource set index of 0

[0200] The PUSCH with the smallest CORESET group index among multiple PUSCHs; for example, the PUSCH with a CORESET group index of 0;

[0201] The PUSCH that starts sending earliest among multiple PUSCHs;

[0202] The earliest scheduled PUSCH among multiple PUSCHs;

[0203] The PUSCH with the highest modulation and coding scheme (MCS) level among multiple PUSCHs.

[0204] The above multiplexing method can be called the sixth method.

[0205] According to the sixth method, the terminal device can use one PUSCH (i.e., the second PUSCH) to transmit the UCI carried by multiple PUCCHs, and the terminal device does not transmit the multiple PUCCHs. Using the sixth method, the terminal device only needs to multiplex the UCI carried by all PUCCHs into one target PUSCH (i.e., the second PUCCH), which is simpler to implement. The PUSCH with the highest MCS level is more reliable as the target PUSCH to carry UCI. The earliest scheduled PUSCH among multiple PUSCHs is used as the target PUSCH, so that the UCI can be transmitted as early as possible, shortening the transmission delay.

[0206] In addition, in some embodiments, for the above three situations, the terminal device may send a first capability of the terminal device to the network device before determining the multiplexing mode. The first capability is used to indicate that the terminal device supports simultaneous transmission of PUCCH and PUSCH associated with different spatial information. The network device may include one or more of a base station, a TRP, an access point, etc.

[0207] Furthermore, the terminal device may receive configuration information of the first transmission mode sent by the network device. When configuring the terminal device for the first transmission mode, the network device may perform the configuration based on whether the terminal device has the first capability. For example, if the terminal device has the first capability, that is, the terminal device supports the simultaneous transmission of PUCCH and PUSCH associated with different spatial information, the network device may configure the first transmission mode for the terminal device, or may not configure the first transmission mode for the terminal device. If the terminal device does not have the first capability, that is, the terminal device does not support the simultaneous transmission of PUCCH and PUSCH associated with different spatial information, the network device may not configure the first transmission mode for the terminal device.

[0208] The network device may use high-layer parameters or a Media Access Control Control Element (MAC CE) to send configuration information of the first transmission mode to the terminal device. In one example, the terminal device receives the configuration information of the first transmission mode sent by the network device, including:

[0209] The terminal device receives a second high-level parameter or MAC CE sent by the network device, where the second high-level parameter or MAC CE carries configuration information of the first transmission mode.

[0210] For example, the second high-level parameter includes one or more of the following:

[0211] PUCCH configuration;

[0212] PUCCH resources;

[0213] PUCCH resource group;

[0214] TCI status;

[0215] TCI uplink status;

[0216] PUSCH configuration.

[0217] In addition, in some embodiments, for the above three situations, the terminal device can send the second capability of the terminal device to the network device before determining the multiplexing method. The second capability is used to indicate that the terminal device supports the simultaneous transmission of multiple PUCCHs associated with different spatial information.

[0218] Furthermore, the terminal device may receive configuration information of the second transmission mode sent by the network device, where the configuration information of the second transmission mode indicates that the terminal device is configured for the second transmission mode, or the configuration information of the second transmission mode indicates that the terminal device is not configured for the second transmission mode. In one example, the second transmission mode includes: multiple PUCCHs associated with different spatial information can be transmitted simultaneously.

[0219] For example, if the terminal device has the second capability, that is, the terminal device supports the simultaneous transmission of multiple PUCCHs associated with different spatial information, and the terminal device reports the second capability to the network device, the network device may configure the second transmission mode for the terminal device, or not configure the second transmission mode for the terminal device. If the terminal device does not have the second capability, that is, the terminal device does not support the simultaneous transmission of multiple PUCCHs associated with different spatial information, the network device may not configure the second transmission mode for the terminal device.

[0220] For example, in the above-mentioned third mode, if the terminal device is pre-configured as the second transmission mode by the network device, the terminal device can determine that the multiplexing mode is the third mode, that is, the UCI carried by the PUCCH with the same spatial information associated with the PUSCH in multiple PUCCHs is multiplexed into the PUCSH, and the PUCCH with different spatial information associated with the PUSCH in multiple PUCCHs is not processed.

[0221] The network device may use high-layer parameters or MAC CE to send configuration information of the second transmission mode to the terminal device. In one example, the terminal device receives the configuration information of the second transmission mode sent by the network device, including:

[0222] The terminal device receives a third high-level parameter or MAC CE sent by the network device, where the third high-level parameter or MAC CE carries configuration information of the second transmission mode.

[0223] For example, the third high-level parameter includes one or more of the following:

[0224] PUCCH configuration;

[0225] PUCCH resources;

[0226] PUCCH resource group;

[0227] TCI status;

[0228] TCI uplink status.

[0229] An embodiment of the present application also proposes a communication method, which is applied to a network device and can configure different first high-level parameters and first transmission modes for a terminal device, and receive UCI sent by the terminal device according to the multiplexing mode corresponding to the first high-level parameters and the first transmission mode.

[0328] The network device in the embodiment of the present application may be a base station, a TRP, an access point (Access Pint) or other devices.

[0329] For a specific example of the network device executing method 400 of this embodiment, reference can be made to the relevant description of the network device in the above method 300, which will not be repeated here for the sake of brevity.

[0330] The following describes the embodiments of the present application in detail with reference to the accompanying drawings.

[0331] In an embodiment of the present application, the terminal device determines that one or more PUCCHs and one or more PUSCHs overlap in the time domain or are sent within a first time unit; wherein,

[0332] One or more PUCCHs include one or more PUCCHs transmitted based on the same or different spatial information.

[0333] The one or more PUSCHs include one or more PUSCHs transmitted based on the same or different spatial information.

[0334] The overlap in the time domain may include complete overlap or partial overlap in the time domain.

[0335] In the above-mentioned case, the terminal device determines the multiplexing mode of the UCI carried by one or more PUCCHs based on the configuration information of the first high-level parameters and at least one of the configuration information of the first transmission mode. The multiplexing mode can be called the target mode, and the terminal device transmits the UCI carried by one or more PUCCHs according to the target mode.

[0336] For different scenarios of PUCCH and PUSCH, the specific description is shown in Examples 1 to 3. In the following embodiments, the terminal device is specifically a UE. The network device may include a base station, a TRP or an access point (Access Pint) and other devices.

[0337] Example 1:

[0338] When a PUCCH and multiple PUSCHs overlap in the time domain or are transmitted within the first time unit, including when a PUCCH associated with one spatial information and multiple PUSCHs associated with multiple different spatial information transmitted simultaneously overlap in the time domain or are transmitted within the first time unit, the overlap in the time domain can be understood as complete overlap or partial overlap in the time domain.

[0339] Figure 5A is a schematic diagram of a PUCCH and multiple PUSCHs completely overlapping in the time domain, Figure 5B is a schematic diagram of a PUCCH and multiple PUSCHs partially overlapping in the time domain, and Figure 5C is a schematic diagram of a PUCCH and multiple PUSCHs being sent in the first time unit.

[0340] The multiple PUSCHs include multiple PUSCHs transmitted simultaneously based on different spatial information.

[0341] The multiple PUSCHs may be PUSCHs scheduled by different downlink control information (DCI), or PUSCHs scheduled by one DCI, or configured grant PUSCHs.

[0342] That is, multiple PUSCHs may all be DCI-scheduled PUSCHs, or all be configured grant PUSCHs, or some may be DCI-scheduled PUSCHs and the other may be configured grant PUSCHs. Multiple DCI-scheduled PUSCHs may be scheduled by different DCIs or by one DCI.

[0343] The UE determines the multiplexing mode of the UCI as a target mode, which may be a first mode or a second mode.

[0344] The first mode: When the UE is configured for the first transmission mode and the UE is configured for multi-DCI scheduled PUSCH transmission (enableSTx2PofmDCI is configured), the UE multiplexes the UCI into the PUSCH with the same spatial information associated with the PUCCH.

[0345] The first transmission mode is that PUCCH and PUSCH associated with different spatial information can be sent simultaneously.

[0346] Figure 6 is a schematic diagram of the first method according to an embodiment of the present application. In Figure 6, PUCCH, PUSCH#1, and PUSCH#2 are sent simultaneously, wherein the spatial information associated with the PUCCH is the same as the spatial information associated with PUSCH#1. When the UE is configured as the first transmission mode, and the UE is configured for multi-DCI scheduled PUSCH transmission, the UE determines that the multiplexing method is the first method; according to the first method, the UE sends PUSCH#1 and PUSCH#2, the UE does not send PUCCH, and uses PUSCH#1 to transmit the UCI carried by the PUCCH. Figure 6 is an example of the complete overlap of PUCCH, PUSCH#1, and PUSCH#2 in the time domain. For the case where PUCCH, PUSCH#1, and PUSCH#2 partially overlap in the time domain, or are sent within the first time unit, the multiplexing method is the same as shown in Figure 6.

[0347] The spatial information may include one or more of the following:

[0348] Joint TCI state or UL TCI state, or,

[0349] Controls the resource collection group index (CoresetPoolIndex), or,

[0350] Sounding reference signal (SRS) resource set, or,

[0351] Reference signals corresponding to spatial relationships, such as SRS, CSI-RS, DMRS, SSB, etc.

[0352] Reference signal corresponding to type D QCL.

[0353] Antenna panel identification or TRP index;

[0354] Beam index.

[0355] In this example, when the first transmission mode is configured, the UE does not need to pay attention to the configuration of the first higher layer parameter and directly multiplexes the UCI carried by the PUCCH according to the first mode.

[0356] Before the UE is configured as the first transmission mode, the process may further include: the UE reporting a first capability, where the first capability may also be referred to as a first UE capability.

[0357] The first UE capability is used to indicate that the UE supports simultaneous transmission of PUCCH and PUSCH associated with different spatial information, including at least the following three cases:

[0358] (1) The first UE capability is applicable to the scenario where both PUCCH and PUSCH are scheduled via multiple DCIs; or

[0359] (2) The first UE capability is applicable to a PUCCH that is a PUCCH sent using an SDM scheme and scheduled by a single DCI or a PUCCH sent using an SFN scheme, and a PUSCH that is a plurality of PUSCHs scheduled by multiple DCIs; or

[0360] (3) The first UE capability is applicable to a case where the PUCCH is a plurality of PUCCHs scheduled by multiple DCIs, and the PUSCH is a PUSCH sent by a single DCI and transmitted in an SDM scheme or a PUSCH sent in an SFN scheme.

[0361] With the first approach, when a UE can simultaneously transmit PUCCHs associated with different spatial relationships, the UCI carried by the PUCCHs can be multiplexed directly using the first approach, regardless of the configuration of the first higher-layer parameter. This simplifies the UCI multiplexing method. Furthermore, spatially-based UCI multiplexing ensures the complete transmission of all information.

[0362] Second mode: When the UE is not configured for the first transmission mode and the UE is configured for PUSCH transmission with multiple DCI scheduling (enableSTx2PofmDCI is configured):

[0363] The UE is not configured with the first transmission mode, which can be understood as the UE not supporting the first UE capability, or the UE supports the first UE capability but the network device is not configured with the first transmission mode.

[0364] If the first higher layer parameter is configured as the first value, the UE multiplexes the UCI into the PUSCH having the same spatial information as that associated with the PUCCH.

[0365] The first high-level parameter is used by the UE to determine whether the backhaul between multiple TRPs is ideal or non-ideal. The first high-level parameter is the HARQ feedback mode configuration, namely, ackNackFeedbackMode. The first value is used to determine whether the backhaul between multiple TRPs is non-ideal. This can be understood as the high-level parameter ackNackFeedbackMode being configured to the first value, separate.

[0366] The first high-layer parameter is used by the UE to determine a UCI multiplexing mode. The first value is used to determine the multiplexing mode: the UE multiplexes the UCI into the PUSCH with the same spatial information as that associated with the PUCCH.

[0367] In this case, when the UE is not configured with the first transmission mode, if the backhaul between multiple TRPs is non-ideal, the UCI carried by the PUCCH can be directly multiplexed according to the second mode, which can simplify the UCI multiplexing process. In addition, UCI multiplexing based on spatial information can ensure the complete transmission of all information.

[0368] If the first higher layer parameter is configured as the second value, the UE multiplexes the UCI into the target PUSCH.

[0369] The target PUSCH is the PUSCH associated with the first joint / UL TCI state; or,

[0370] The target PUSCH is a PUSCH with a smaller associated antenna panel identifier or TRP index, for example, the antenna panel identifier or TRP index is 0; or,

[0371] The target PUSCH is a PUSCH with a smaller associated SRS resource set index, for example, the SRS resource set index is 0; or,

[0372] The target PUSCH is a PUSCH with a smaller associated reference signal resource index or reference signal resource set index, for example, an index or set index of 0; or

[0373] The target PUSCH is a PUSCH with a smaller associated CORESET group index, for example, the CORESET group index is 0; or

[0374] The target PUSCH is the PUSCH that starts sending earliest among multiple PUSCHs, or,

[0375] The target PUSCH is the earliest scheduled PUSCH among multiple PUSCHs, or,

[0376] The target PUSCH is the PUSCH with the highest modulation and coding scheme (MCS) level among multiple PUSCHs.

[0377] The first high-level parameter is used by the UE to determine whether the backhaul between multiple TRPs is ideal or non-ideal. The first high-level parameter is the HARQ feedback mode configuration, namely ackNackFeedbackMode. The second value is used to determine whether the backhaul between multiple TRPs is ideal. This can be understood as the high-level parameter ackNackFeedbackMode being configured to the second value joint.

[0378] The first high-layer parameter is used by the UE to determine a UCI multiplexing mode, and the second value is used to determine a multiplexing mode in which the UE multiplexes the UCI into a target PUSCH.

[0379] In this case, multiplexing only requires one target PUSCH, making implementation simpler. Using the PUSCH with the highest MCS level as the target PUSCH increases the reliability of carrying UCI. Using the earliest scheduled PUSCH among multiple PUSCHs as the target PUSCH allows for earlier UCI transmission, shortening UCI transmission latency.

[0380] Example 2:

[0381] When multiple PUCCHs overlap with one PUSCH in the time domain or are transmitted within the first time unit, where the multiple PUCCHs are multiple PUCCHs that are transmitted based on different spatial information and are transmitted in SFN mode with a single DCI schedule, or the multiple PUCCHs are PUCCHs that are transmitted based on different spatial information and are transmitted with multiple DCI schedules, or the multiple PUCCHs are PUCCHs that are transmitted based on different spatial information and are transmitted in SDM mode with a single DCI schedule. Among the multiple PUCCHs, the spatial information associated with one of the PUCCHs is the same as the spatial information associated with the PUSCH. The overlap in the time domain can be understood as complete overlap or partial overlap in the time domain.

[0382] Figure 7A is a schematic diagram of multiple PUCCHs and one PUSCH completely overlapping in the time domain, Figure 7B is a schematic diagram of multiple PUCCHs and one PUSCH partially overlapping in the time domain, and Figure 7C is a schematic diagram of multiple PUCCHs and one PUSCH being sent in the first time unit.

[0383] The PUCCH may be triggered by one or more PDCCHs, and the PDCCH may carry DCI format 1-1 or 1-2; or the PUCCH is a PUCCH configured through RRC signaling.

[0384] The spatial information configuration associated with the PUCCH resources corresponding to the multiple PUCCHs is to apply multiple spatial information.

[0385] The UCI carried by the PUCCH may include HARQ, and / or CSI, and / or Selective Repeat (SR).

[0386] The UE determines that the multiplexing mode of the UCI is a target mode, which is the third mode or the fourth mode.

[0387] The third mode: When the UE is configured with the first transmission mode, the UE multiplexes the UCI carried by the PUCCH with the same spatial information as the PUSCH in multiple PUCCHs into the PUSCH with the same spatial information, and does not process the PUCCH with different spatial information from the PUSCH in multiple PUCCHs.

[0388] Figure 8 is a schematic diagram of the third method of an embodiment of the present application. In Figure 8, PUCCH#1, PUCCH#2, and PUSCH#1 are transmitted simultaneously, wherein the spatial information associated with PUCCH#1 is the same as the spatial information associated with PUSCH#1. When the UE is configured as the first transmission mode, the UE determines that the multiplexing mode is the third mode; according to the third mode, the UE transmits PUSCH#1 and PUCCH#2, the UE does not transmit PUCCH#1, and uses PUSCH#1 to transmit the UCI carried by PUCCH#1. That is, the UCI carried by PUCCH#1 is multiplexed into PUSCH#1, and the UE can transmit PUCCH#2 and PUSCH#1 simultaneously without transmitting PUCCH#1. Figure 8 is an example of the case where PUCCH#1, PUCCH#2, and PUSCH#1 completely overlap in the time domain. For the case where PUCCH#1, PUCCH#2, and PUSCH#1 partially overlap in the time domain, or are transmitted within the first time unit, the multiplexing mode is the same as shown in Figure 8.

[0389] Before the UE is configured as the first transmission mode, the process may further include: the UE reporting a first capability, where the first capability may also be referred to as a first UE capability.

[0390] The first UE capability is used to indicate that the UE supports simultaneous transmission of PUCCH and PUSCH associated with different spatial information, including at least the following three cases:

[0391] (1) The first UE capability is applicable to the scenario where both PUCCH and PUSCH are scheduled via multiple DCIs; or

[0392] (2) The first UE capability is applicable to a PUCCH that is a PUCCH sent using an SDM scheme and scheduled by a single DCI or a PUCCH sent using an SFN scheme, and a PUSCH that is a plurality of PUSCHs scheduled by multiple DCIs; or

[0393] (3) The first UE capability is applicable to a case where the PUCCH is a plurality of PUCCHs scheduled by multiple DCIs, and the PUSCH is a PUSCH sent by a single DCI and transmitted in an SDM scheme or a PUSCH sent in an SFN scheme.

[0394] The network device may configure the first transmission mode for the UE or not configure the first transmission mode for the UE based on the first UE capability reported by the UE. For example, if the UE has the first UE capability, the network device may configure the first transmission mode for the UE or not configure the first transmission mode for the UE. If the UE does not have the first UE capability, the network device does not configure the first transmission mode for the UE.

[0395] Before the UE is configured as the first transmission mode, the method may further include: the UE is configured as the second transmission mode

[0396] The second transmission mode is that multiple PUCCHs associated with different spatial information scheduled by multiple DCIs can be sent simultaneously.

[0397] Before the UE is configured as the second transmission mode, the method further includes: the UE reports a second capability, which may also be referred to as a second UE capability;

[0398] The second UE capability is that the UE supports simultaneous transmission of multiple PUCCHs associated with different spatial information scheduled by multiple DCIs.

[0399] The network device may configure the second transmission mode for the UE or not configure the second transmission mode for the UE based on the second UE capability reported by the UE. For example, if the UE has the second UE capability, the network device may configure the second transmission mode for the UE or not configure the second transmission mode for the UE. If the UE does not have the second UE capability, the network device does not configure the second transmission mode for the UE.

[0400] In the scenario of this embodiment, when the UE supports the first capability, PUCCH / PUSCH associated with different coreset Pool Indexes are allowed to overlap in the time domain or be sent within the first time unit.

[0401] The fourth method:

[0402] When the UE is not configured with the first transmission mode:

[0403] (1) If the first high-level parameter is configured as the first value, there are several possibilities:

[0404] The first possibility is that the UE does not expect this situation and can treat it as an error case.

[0405] The second possibility is that the UCI carried by the PUCCH associated with the same spatial information is multiplexed into the PUSCH, and the PUCCH with spatial information different from that of the PUSCH is not transmitted.

[0406] This situation may be applicable to PUCCHs that are sent in SFN / SDM manner and are scheduled by a single DCI and multiple PUCCHs.

[0407] For PUCCHs scheduled with a single DCI, only the UCI carried by one of the PUCCHs is sent, and the PUCCH corresponding to the other spatial relationship is discarded. Although this reduces the diversity gain of PUCCH transmission, the probability that the base station can correctly receive the UCI carried by the PUCCH is relatively high, and the correct transmission of PUSCH is guaranteed.

[0408] Figure 9A is a schematic diagram of the fourth method of an embodiment of the present application. In Figure 9A, PUCCH#1, PUCCH#2, and PUSCH#1 are transmitted simultaneously, where the spatial information associated with PUCCH#1 is the same as the spatial information associated with PUSCH#1. When the UE is not configured for the first transmission mode, the UE determines that the multiplexing mode is the fourth mode; according to the fourth mode, the UE transmits PUSCH#1, does not transmit PUCCH#1 and PUCCH#2, and uses PUSCH#1 to transmit the UCI carried by PUCCH#1. In other words, the UCI carried by PUCCH#1 is multiplexed into PUSCH#1, and the UE transmits PUSCH#1 without transmitting PUCCH#1 and PUCCH#2. Figure 9A is an example of a situation where PUCCH#1, PUCCH#2, and PUSCH#1 completely overlap in the time domain. For situations where PUCCH#1, PUCCH#2, and PUSCH#1 partially overlap in the time domain or are transmitted within the first time unit, the multiplexing mode is the same as shown in Figure 9A.

[0409] The third possibility: If the priority corresponding to the priority indexes of multiple PUCCHs is higher than the priority corresponding to the priority index of PUSCH, the PUSCH is discarded and only multiple PUCCHs are transmitted; if the priority corresponding to the priority indexes of multiple PUCCHs is lower than or equal to the priority corresponding to the priority index of PUSCH, the UCI carried by the PUCCH associated with the same spatial information is multiplexed into the PUSCH, and the PUCCH with different spatial information from the PUSCH is not transmitted.

[0410] Figure 9B is a second schematic diagram of the fourth method of an embodiment of the present application. In Figure 9B, PUCCH#1, PUCCH#2, and PUSCH#1 are transmitted simultaneously, where the priority corresponding to the priority index of PUCCH#1 is the same as the priority corresponding to the priority index of PUCCH#2. If the priority corresponding to the priority index of PUCCH#1 / PUCCH#2 is higher than the priority corresponding to the priority index of PUSCH#1, PUSCH#1 is discarded and only multiple PUCCHs are transmitted, such as only PUCCH#1 and PUCCH#2 in Figure 9B. If the priority corresponding to the priority index of PUCCH#1 / PUCCH#2 is lower than or equal to the priority corresponding to the priority index of PUSCH#1, the UCI carried by the PUCCH associated with the same spatial information is multiplexed into the PUSCH, and PUCCHs with different spatial information from the PUSCH are not transmitted. Taking Figure 9B as an example, if the spatial information associated with PUCCH#1 is the same as the spatial information associated with PUSCH#1, and the spatial information associated with PUCCH#2 is different from the spatial information associated with PUSCH, the UCI carried by PUCCH#1 is multiplexed onto the PUSCH, and the UE transmits PUSCH#1 carrying the UCI. The UE does not transmit PUCCH#1 or PUCCH#2. Figure 9B illustrates the case where PUCCH#1, PUCCH#2, and PUSCH#1 completely overlap in the time domain. If PUCCH#1, PUCCH#2, and PUSCH#1 partially overlap in the time domain, or are transmitted within the first time unit, the multiplexing method shown in Figure 9B is the same.

[0411] This situation may be applicable to the case where multiple PUCCHs are PUCCHs scheduled by multiple DCIs.

[0412] Determining the multiplexing method based on the physical channel priority can ensure the transmission of high-priority channels and guarantee the integrity of information transmission to a certain extent.

[0413] (2) If the first higher layer parameter is configured as the second value, the UCI carried by multiple PUCCHs are multiplexed into the PUSCH.

[0414] In this example, the UE is not configured with the first transmission mode, which can be understood as the UE not supporting the first UE capability; or it can be understood as the UE supporting the first UE capability, but the network device does not configure the first transmission mode for the UE.

[0415] Figure 9C is a schematic diagram of the third fourth mode of an embodiment of the present application. In Figure 9C, PUCCH#1, PUCCH#2, and PUSCH#1 are transmitted simultaneously, wherein the spatial information associated with PUCCH#1 is the same as the spatial information associated with PUSCH#1, and the spatial information associated with PUCCH#2 is different from the spatial information associated with PUSCH#1. When the UE is not configured for the first transmission mode, the UE determines that the multiplexing mode is the fourth mode; according to the fourth mode, the UE transmits PUSCH#1, the UE does not transmit PUCCH#1 and PUCCH#2, and uses PUSCH#1 to transmit the UCI carried by PUCCH#1 and the UCI carried by PUCCH#2. In other words, the UCI carried by PUCCH#1 and the UCI carried by PUCCH#2 are both multiplexed into PUSCH#1, and the UE transmits PUSCH#1 and does not transmit PUCCH#1 and PUCCH#2. Figure 9C is an example of PUCCH#1, PUCCH#2, and PUSCH#1 completely overlapping in the time domain. For the case where PUCCH#1, PUCCH#2, and PUSCH#1 partially overlap in the time domain, or are sent within the first time unit, the multiplexing method is the same as that shown in Figure 9C.

[0416] In this case, when the backhaul between multiple TRPs is ideal, it is only necessary to put all the UCI carried by the multiplexed PUCCH into one PUSCH, which is simpler to implement.

[0417] Example 3:

[0418] In this embodiment, the multiplexing mode may only be related to the first higher layer parameter and may be unrelated to the first UE capability / first transmission mode.

[0419] In this embodiment, multiple PUCCHs and multiple PUSCHs overlap in the time domain or are transmitted within the first time unit, wherein the multiple PUCCHs may be multiple PUCCHs transmitted based on different spatial information and scheduled by multiple DCIs, and the multiple PUSCHs may be multiple PUSCHs transmitted based on different spatial information and scheduled by multiple DCIs. Overlap in the time domain may include partial overlap or complete overlap. Figure 10 is a schematic diagram of complete overlap of multiple PUCCHs and multiple PUSCHs in the time domain.

[0420] Among them, the multiple PUSCHs include multiple PUSCHs transmitted simultaneously based on different spatial information. The multiple PUSCHs can be PUSCHs scheduled by different downlink control information (DCI), or PUSCHs scheduled by one DCI, or configured grant PUSCHs. That is, the multiple PUSCHs can all be PUSCHs scheduled by DCI, or all be configured grant PUSCHs, or some can be PUSCHs scheduled by DCI and the other can be configured grant PUSCHs. For multiple PUSCHs scheduled by DCI, they can be scheduled by different DCIs or by one DCI.

[0421] The multiple PUCCHs are multiple PUCCHs transmitted in an SFN manner based on different spatial information and scheduled by a single DCI, or the multiple PUCCHs are PUCCHs transmitted in an SDM manner based on different spatial information and scheduled by multiple DCIs, or the multiple PUCCHs are PUCCHs transmitted in an SDM manner based on different spatial information and scheduled by a single DCI.

[0422] The UE determines the multiplexing mode of the UCI as a target mode, which is the fifth mode.

[0423] Fifth mode: If the first high-layer parameter is configured as the first value, the UE multiplexes the UCI associated with the target spatial information into the PUSCH associated with the same target spatial information, where the target spatial information is any one of the spatial information associated with multiple PUCCHs or PUSCHs.

[0424] Figure 11 is a schematic diagram of the fifth mode of an embodiment of the present application. In Figure 11, PUCCH#1, PUCCH#2, PUSCH#1, and PUSCH#2 are transmitted simultaneously, wherein the spatial information associated with PUCCH#1 is the same as the spatial information associated with PUSCH#1, and the spatial information associated with PUCCH#2 is the same as the spatial information associated with PUSCH#2. When the first high-layer parameter of the UE is configured to the first value, the UE determines that the multiplexing mode is the fifth mode; according to the fifth mode, the UE transmits PUSCH#1 and PUSCH#2, the UE does not transmit PUCCH#1 and PUCCH#2, and uses PUSCH#1 to transmit the UCI carried by PUCCH#1, and uses PUSCH#2 to transmit the UCI carried by PUCCH#2. That is, the UCI carried by PUCCH#1 is multiplexed into PUSCH#1 associated with the same spatial information, and the UCI carried by PUCCH#2 is multiplexed into PUSCH#2 associated with the same spatial information. The UE can send PUSCH#1 and PUSCH#2 simultaneously, without sending PUCCH#1 and PUCCH#2. Figure 11 illustrates the case where PUCCH#1, PUCCH#2, PUSCH#1, and PUSCH#2 completely overlap in the time domain. If PUCCH#1, PUCCH#2, PUSCH#1, and PUSCH#2 partially overlap in the time domain, or are sent within the first time unit, the multiplexing method shown in Figure 11 is the same.

[0425] This multiplexing method can multiplex UCI according to spatial information to ensure the complete transmission of all information.

[0426] Sixth mode: If the first high-level parameter is configured as the second value, the terminal device multiplexes the UCI carried by multiple PUCCHs into one PUSCH, such as multiplexing into a target PUSCH. The target PUSCH may include one or more of the following:

[0427] Associated with the first joint / UL TCI state PUSCH; or,

[0428] The PUSCH with a smaller associated antenna panel identifier or TRP index, for example, the antenna panel identifier or TRP index is 0; or

[0429] A PUSCH with a smaller associated SRS resource set index, such as an SRS resource set index of 0; or

[0430] The PUSCH with the smaller associated reference signal resource index or reference signal resource set index, for example, the index or set index is 0; or

[0431] The PUSCH with a smaller CORESET group index, for example, CORESET group index 0; or

[0432] The earliest PUSCH to start transmission among multiple PUSCHs, or

[0433] The earliest scheduled PUSCH among multiple PUSCHs, or

[0434] The PUSCH with the highest MCS level among multiple PUSCHs.

[0435] Figure 12 is a schematic diagram of the sixth mode of an embodiment of the present application. In Figure 12, PUCCH#1, PUCCH#2, PUSCH#1, and PUSCH#2 are sent simultaneously. When the first high-layer parameter of the UE is configured as the second value, the UE determines that the multiplexing mode is the sixth mode; according to the sixth mode, the UE sends PUSCH#1 and PUSCH#2, and the UE does not send PUCCH#1 and PUCCH#2; in the example shown in Figure 12, PUSCH#1 is the target PUSCH, then the UE uses PUSCH#1 to transmit the UCI carried by PUCCH#1 and the UCI carried by PUCCH#2. That is to say, the UCI carried by PUCCH#1 and the UCI carried by PUCCH#2 are both multiplexed in the target PUSCH, and the UE can send PUSCH#1 and PUSCH#2 at the same time, and does not send PUCCH#1 and PUCCH#2. Figure 12 is an example of PUCCH#1, PUCCH#2, PUSCH#1, and PUSCH#2 completely overlapping in the time domain. For the case where PUCCH#1, PUCCH#2, PUSCH#1, and PUSCH#2 partially overlap in the time domain or are sent within the first time unit, the multiplexing method is the same as shown in Figure 12.

[0436] This approach simplifies implementation by multiplexing UCI carried by multiple PUCCHs into a single target PUSCH. Using the PUSCH with the highest MCS level as the target PUSCH for UCI transmission improves reliability. Using the earliest scheduled PUSCH among multiple PUSCHs as the target PUSCH allows for earlier UCI transmission, shortening transmission latency.

[0437] Example 4:

[0438] In the aforementioned embodiments 1 to 3, the network device configures the first transmission mode and the second transmission mode for the UE. This embodiment introduces a configuration method for the first transmission mode and the second transmission mode, which can be applied to embodiments 1 to 3.

[0439] (1) Configuration of the first transmission mode:

[0440] The first configuration method: The configuration information of the first transmission mode is carried in the high-level parameter PUCCH-Config. For example, the configuration is performed by enumeration. For example, if the first transmission mode in the high-level parameter PUCCH-Config is configured as true (true), it means that the UE is configured as the first transmission mode; if the first transmission mode in the high-level parameter PUCCH-Config is configured as false (false) or the first transmission mode is not configured, it means that the UE is not configured as the first transmission mode. Alternatively, if the first transmission mode in the high-level parameter PUCCH-Config is configured as false (false), it means that the UE is configured as the first transmission mode; if the first transmission mode in the high-level parameter PUCCH-Config is configured as true (true), it means that the UE is not configured as the first transmission mode. An example of configuring the first transmission mode of the high-level parameter PUCCH-Config is as follows:

[0441] The configuration is performed using PUCCH-Config, which has a wider range of configurations. All resources included in the PUCCH-Config can be configured with the first transmission mode.

[0442] The second configuration method: The configuration information of the first transmission mode is carried in the high-level parameter PUCCH-resource or PUCCH-ResourceGroup. For example, the configuration is performed by enumeration. For example, if the first transmission mode in the high-level parameter PUCCH-resource or PUCCH-ResourceGroup is configured as true (true), it means that the UE is configured as the first transmission mode; if the first transmission mode in the high-level parameter PUCCH-resource or PUCCH-ResourceGroup is configured as false (false) or the first transmission mode is not configured, it means that the UE is not configured as the first transmission mode. Alternatively, if the first transmission mode in the high-level parameter PUCCH-resource or PUCCH-ResourceGroup is configured as false (false), it means that the UE is configured as the first transmission mode; if the first transmission mode in the high-level parameter PUCCH-resource or PUCCH-ResourceGroup is configured as true (true), it means that the UE is not configured as the first transmission mode. An example of configuring the first transmission mode of the high-level parameter PUCCH-ResourceGroup is as follows:

[0443] The high-level parameter PUCCH-resource is used for configuration, and the first transmission mode can be configured with resource as the granularity, and different configurations can be performed on different resources.

[0444] An example of configuring the first transmission mode using the higher-layer parameter PUCCH-ResourceGroup is as follows:

[0445] The high-level parameter PUCCH-ResourceGroup is used for configuration. The configuration range is larger than that of using PUCCH-resource and smaller than that of using PUCCH-Config, and can be flexibly configured.

[0446] The third configuration method: the configuration information of the first transmission mode is carried in the high-level parameter TCI-State. For example, the configuration is performed by enumeration. For example, if the first transmission mode in the high-level parameter TCI-State is configured as true (true), it means that the UE is configured as the first transmission mode; if the first transmission mode in the high-level parameter TCI-State is configured as false (false) or the first transmission mode is not configured, it means that the UE is not configured as the first transmission mode. Alternatively, if the first transmission mode in the high-level parameter TCI-State is configured as false (false), it means that the UE is configured as the first transmission mode; if the first transmission mode in the high-level parameter TCI-State is configured as true (true), it means that the UE is not configured as the first transmission mode.

[0447] The fourth configuration method: the configuration information of the first transmission mode is carried in the high-level parameter TCI-UL-State. For example, the configuration is performed by enumeration. For example, if the first transmission mode in the high-level parameter TCI-UL-State is configured as true (true), it means that the UE is configured as the first transmission mode; if the first transmission mode in the high-level parameter TCI-UL-State is configured as false (false) or the first transmission mode is not configured, it means that the UE is not configured as the first transmission mode. Alternatively, if the first transmission mode in the high-level parameter TCI-UL-State is configured as false (false), it means that the UE is configured as the first transmission mode; if the first transmission mode in the high-level parameter TCI-UL-State is configured as true (true), it means that the UE is not configured as the first transmission mode.

[0448] In the fifth configuration method, the configuration information of the first transmission mode is carried in a MAC CE. For example, the MAC CE is carried in a MAC CE with a unified TCI state activation / deactivation. The MAC CE structure includes one or more of the following:

[0449] The first transmission mode; 1 bit can be used to indicate

[0450] Serving cell ID;

[0451] Downlink BWP ID;

[0452] Uplink BWP ID;

[0453] The number indication field of the TCI status corresponding to the TCI codepoint;

[0454] Unified TCI status / downlink TCI status, or uplink TCI status;

[0455] TCI status ID;

[0456] Reserved bit.

[0457] In association with the unified TCI state, when two TCI states are configured, the configuration state of the first transmission mode can be adjusted more flexibly compared to RRC signaling.

[0458] The sixth configuration method: the configuration information of the first transmission mode is carried in PUSCH-Config. For example, the configuration is performed by enumeration. For example, if the first transmission mode in the high-level parameter PUSCH-Config is configured as true (true), it means that the UE is configured as the first transmission mode; if the first transmission mode in the high-level parameter PUSCH-Config is configured as false (false) or the first transmission mode is not configured, it means that the UE is not configured as the first transmission mode. Alternatively, if the first transmission mode in the high-level parameter PUSCH-Config is configured as false (false), it means that the UE is configured as the first transmission mode; if the first transmission mode in the high-level parameter PUSCH-Config is configured as true (true), it means that the UE is not configured as the first transmission mode. An example of configuring the first transmission mode of the high-level parameter PUSCH-Config is as follows:

[0459] (2) Configuration of the second transmission mode:

[0460] The first configuration method: carried in the higher-layer parameter PUCCH-Config;

[0461] The second configuration method: carried in the higher-layer parameters PUCCH-resource or PUCCH-ResourceGroup;

[0462] The third configuration method: carried in the high-level parameter TCI-State;
