     TECHNICAL FIELD 
     This application relates to the field of communications technologies, and in particular, to an uplink transmission method and apparatus, an uplink receiving method and apparatus, a device, and a storage medium. 
     BACKGROUND 
     In some communications systems, a terminal usually needs to send uplink control information (UCI) to a network-side device. Further, an uplink skipping (UL skipping) function may be configured in some scenarios. For a carrier on which the uplink skipping function is enabled by the terminal, uplink transmission on the carrier is sent only when data is transmitted at a medium access control (MAC) layer of the carrier. In this case, the network-side device does not know whether the terminal sends uplink transmission on some carriers, that is, the network-side device is not sure of whether the terminal sends uplink transmission on some carriers. In this case, in a case that the terminal is configured with a plurality of carriers and the uplink skipping function is enabled on all the plurality of carriers, the network-side device cannot determine a specific carrier on which uplink control information is to be transmitted. Therefore, the network-side device may need to perform blind detection on the plurality of carriers to receive the uplink control information, resulting in high complexity of blind detection by the network-side device.

     The following describes in detail an uplink transmission method and apparatus, an uplink receiving method and apparatus, a device, and a storage medium provided in the embodiments of this application with reference to the accompanying drawings and by using specific embodiments and application scenarios thereof. 
       FIG.  2    is a flowchart of an uplink transmission method according to an embodiment of this application. The method is applied to a terminal, and as shown in  FIG.  2   , includes the following steps. 
     Step  201 : In a case that an uplink control channel conflicts with an uplink data channel, perform multiplexing transmission for uplink control information and uplink transmission. 
     A transmission resource of the uplink transmission and a transmission resource of the uplink control channel overlap, and the uplink transmission meets a preset condition. 
     That the uplink control channel conflicts with the uplink data channel may be that the transmission resource of the uplink control channel conflicts with a transmission resource of the uplink data channel, for example, some resources overlap, or all resources overlap. 
     The uplink transmission and the uplink data channel may belong to one carrier or different carriers. That the transmission resource of the uplink transmission and the transmission resource of the uplink control channel overlap may be that the transmission resource of the uplink transmission and the transmission resource of the uplink control channel partially or completely overlap. 
     The preset condition is known to a network-side device. For example, the preset condition may be agreed upon in a protocol, configured by the network-side device for the terminal, or pre-negotiated upon by the terminal and the network-side device, or the like. 
     It should be noted that, in this embodiment of this application, the uplink transmission may be understood as an uplink signal, for example, uplink data (for example, data information) or an uplink report, for example, an uplink signal transmitted through a physical uplink shared channel (PUSCH). 
     In addition, the uplink control channel in this embodiment of this application may be a physical uplink control channel (PUCCH). 
     Further, the terminal may generate the uplink control information before performing step  201 . 
     In this embodiment of this application, because multiplexing transmission is performed for the uplink control information and the uplink transmission that meets the preset condition, the network-side device can obtain the uplink control information by performing blind detection on the uplink transmission that meets the preset condition, thereby reducing complexity of blind detection by the network-side device. Further, when sending the uplink control information, the terminal does not need to determine a specific carrier on which data is transmitted at a MAC layer, but directly multiplexes the uplink control information to the uplink transmission that meets the preset condition, thereby reducing complexity of multiplexing the uplink control information and the uplink transmission by the terminal. 
     For example, when the terminal is configured with one or more (M, where M&gt;2) carriers, when a resource conflict occurs between the uplink control channel and an uplink DG or CG data channel, and when the network-side device enables (or referred to as enabling) an uplink transmission skipping (UL skipping) function in an uplink data channel of one or N (1&lt;N≤M) carriers of the terminal, the network-side device can still determine a specific carrier on which the uplink control information is multiplexed to an uplink data channel, to reduce blind detection by the network-side device, and reduce complexity of multiplexing the uplink control information and the uplink transmission by the terminal. 
     In addition, this embodiment of the application may be applied to a dynamic grant (DG) or configured grant (CG) scenario. For example, the uplink transmission may be DG uplink transmission or CG uplink transmission. 
     In an optional implementation, in a case that the uplink data channel is a dynamic grant, the preset condition includes: 
     a carrier to which the uplink transmission belongs is a carrier on which an uplink skipping (UL skipping) function is prohibited from being enabled or is not configured, where 
     the carrier on which the uplink skipping function is prohibited from being enabled or is not configured includes at least one of the following: 
     a primary carrier or a carrier with the smallest carrier index in a carrier group. 
     The primary carrier may include at least one of the following: 
     a primary cell (PCell) or a primary secondary cell (PSCell). 
     The carrier with the smallest carrier index in the carrier group may be an active carrier with the smallest carrier index number in the carrier group. In addition, the carrier group may be a cell group. 
     For example, when the terminal is configured with carrier aggregation and is configured with a PCell and a PUCCH SCell, the first PUCCH cell group needs to include a PCell, but cannot include a PUCCH SCell, where the smallest carrier index number in the first PUCCH cell group corresponds to the PCell, and the index number may be 0; and the second PUCCH cell group includes carriers other than all carriers in the first PUCCH cell group, where a correspondence of the smallest carrier index number in the second PUCCH cell group depends on the smallest value of all carrier index numbers in the second PUCCH cell group. 
     The carrier on which the uplink skipping function is prohibited from being enabled or is not configured may be understood as follows: The uplink skipping function of the terminal cannot be enabled (or referred to as being enabled) on the primary carrier and/or the carrier with the smallest carrier index. 
     In this implementation, because the carrier to which the uplink transmission belongs is a carrier on which the uplink skipping function is prohibited from being enabled or is not configured, the network-side device can obtain the uplink control information by performing blind detection only on the carrier, so that complexity of blind detection by the network-side device can be reduced. Further, because the carrier to which the uplink transmission belongs is a carrier on which the uplink skipping function is prohibited from being enabled or is not configured, the terminal does not need to determine a specific carrier on which data is transmitted at a MAC layer. A reason is that, for the carrier on which the uplink skipping function is prohibited from being enabled or is not configured, the terminal may directly perform multiplexing transformation for the uplink control information and uplink transmission on the carrier. 
     Further, in this implementation, the carrier to which the uplink transmission belongs may be the same as the carrier to which the uplink data channel belongs, or the uplink transmission may be dynamic grant uplink transmission. 
     In an optional implementation, the preset condition includes: 
     the uplink transmission is uplink transmission scheduled by the network-side device. 
     The uplink transmission scheduled by the network-side device may be dynamic grant or configured grant uplink transmission scheduled by the network-side device. 
     The uplink transmission scheduled by the network-side device may be that the terminal receives a scheduling message sent by the network-side device, and generates the uplink transmission based on the scheduling message. 
     Further, the uplink transmission scheduled by the network-side device may be uplink transmission scheduled when the network-side device is not sure of whether uplink transmission is sent on one or more carriers. For example, the network-side device is not sure of whether uplink transmission is sent on a carrier, of the terminal, on which the uplink skipping function is enabled, and schedules the uplink transmission, so that the terminal performs multiplexing transmission for the uplink control information and the uplink transmission. For another example, the network-side device is not sure of whether uplink transmission is sent on a configured grant carrier of the terminal, and schedules the uplink transmission, so that the terminal performs multiplexing transmission for the uplink control information and the uplink transmission. 
     In this implementation, because multiplexing transmission is performed for the uplink control information and the uplink transmission scheduled by the network-side device, the terminal does not need to determine a specific carrier on which data is transmitted at a MAC layer, thereby reducing complexity of multiplexing the uplink control information and the uplink transmission by the terminal. In addition, the network-side device can directly perform blind detection on the uplink transmission to obtain the uplink control information, thereby further reducing complexity of blind detection by the network-side device. 
     Optionally, the uplink data channel is a dynamic grant or a configured grant. 
     In a case that the uplink data channel is a configured grant, the uplink transmission may be dynamic grant or configured grant uplink transmission. For example, for a configured grant carrier, when the network-side device is not sure of whether uplink transmission is performed on a configured grant of the carrier, the network-side device may schedule determined uplink transmission on a dynamic or configured grant of the carrier or another carrier, so that the terminal multiplexes the uplink control information to the determined uplink transmission. 
     In a case that the uplink data channel is a dynamic grant, the uplink transmission may be configured grant or dynamic grant uplink transmission. 
     Optionally, in a case that the uplink data channel is a dynamic grant, the terminal enables an uplink skipping function on at least one carrier, and the uplink data channel belongs to the carrier on which the uplink skipping function is enabled. 
     In this implementation, the network-side device can schedule the uplink transmission when the uplink data channel of the carrier on which the uplink skipping function is enabled conflicts with the uplink control channel. For example, when the network-side device cannot determine whether uplink transmission is performed on the carrier, of the terminal, on which the uplink skipping function is enabled, and a resource conflict occurs between the resource of the uplink control channel and the indeterminate uplink transmission, the network-side device schedules uplink transmission, where the network-side device determines that the uplink transmission is to be sent by the terminal. An uplink data channel occupied by the uplink transmission overlaps the resource of the uplink control channel, so that the uplink control information is multiplexed to the determined uplink transmission. 
     Further, in this implementation, the carrier, of the terminal, on which the uplink skipping function is prohibited from being enabled or is not configured may include at least one of the following: 
     a primary carrier or a carrier with the smallest carrier index in a carrier group. 
     In this implementation, the uplink transmission scheduled by the network-side device may be dynamic grant uplink transmission, for example, dynamic grant uplink transmission on the carrier on which the uplink skipping function is prohibited from being enabled or is not configured. Certainly, this is not limited, and the uplink transmission scheduled by the network-side device may be alternatively configured grant uplink transmission. 
     Optionally, the carrier to which the uplink transmission belongs is the same as or different from the carrier to which the uplink data channel belongs. 
     In this implementation, the network-side device can schedule uplink transmission on a carrier that is the same as or different from the carrier to which the uplink data channel belongs, to improve flexibility of scheduling. In addition, the uplink skipping function may not be enabled or configured on the carrier to which the uplink transmission belongs, or the uplink skipping function is enabled on the carrier to which the uplink transmission belongs. For example, the uplink transmission scheduled by the network-side device may be scheduling of a PUSCH on any carrier on which the uplink skipping function is not enabled. 
     Optionally, in a case that the carrier to which the uplink transmission belongs is the same as the carrier to which the uplink data channel belongs, the uplink skipping function is enabled on the carrier to which the uplink transmission belongs; or 
     in a case that the carrier to which the uplink transmission belongs is different from the carrier to which the uplink data channel belongs, the uplink skipping function is not enabled or configured on the carrier to which the uplink transmission belongs, or the uplink skipping function is enabled on the carrier to which the uplink transmission belongs. 
     For example, the uplink transmission may be uplink transmission triggered on any carrier, or the uplink transmission may be scheduling of a PUSCH on any carrier on which uplink skipping is not enabled or is not configured. 
     It should be noted that, if the uplink data channel is configured grant uplink data channel, in a case that the carrier to which the uplink transmission belongs is the same as the carrier to which the uplink data channel belongs, the carrier to which the uplink transmission belongs may be alternatively a carrier on which the uplink skipping function is not enabled or is not configured. 
     Optionally, the uplink transmission includes: 
     aperiodic channel state information (A-CSI). 
     For example, the network-side device may schedule the terminal to send the A-CSI on any carrier. This can reduce complexity of blind detection by the network-side device and reduce complexity of multiplexing the uplink control information and the uplink transmission by the terminal, and can further enable the terminal to report channel state information in a timely manner. 
     It should be noted that, in this embodiment of this application, the uplink transmission is not limited to the A-CSI, and may be alternatively information that may be reported by another terminal, or may be uplink transmission filled with a preset bit or a PUSCH scheduled on any other carrier on which uplink skipping is not enabled or is not configured. 
     For example, for a configured grant carrier, when the network-side device is not sure of whether uplink transmission is performed on a configured grant of the carrier, the network-side device may schedule determined uplink transmission on the carrier or another carrier, so that the terminal multiplexes the uplink control information to the determined uplink transmission. The uplink transmission may be A-CSI of a triggered uplink data channel, or may be a DG PUSCH scheduled on a carrier on which the uplink skipping function is not enabled or is not configured. 
     In an optional implementation, the preset condition includes: 
     the uplink transmission is a configured grant. 
     In this implementation, the uplink control information can be directly multiplexed to uplink transmission of a configured grant carrier. In addition, the uplink transmission and the uplink data channel belong to one carrier, that is, the uplink control information and the uplink transmission are multiplexed in the uplink data channel for transmission. 
     Optionally, the uplink transmission includes: 
     uplink transmission generated in a case that data transmission is performed on the carrier to which the uplink transmission belongs; or 
     uplink transmission generated in a case that no data transmission is performed on the carrier to which the uplink transmission belongs. 
     In this implementation, regardless of whether configured grant data transmission is performed, a MAC layer of the terminal generates a MAC protocol data unit PDU and delivers the PDU to a physical layer. The physical layer multiplexes the uplink control information to the configured grant uplink data channel, that is, multiplexes the uplink control information to the uplink transmission. 
     In this implementation, the uplink transmission can be generated in a case that data transmission is performed or no data transmission is performed on the carrier to which the uplink transmission belongs. This can reduce complexity of multiplexing the uplink control information and the uplink transmission by the terminal, and reduce complexity of blind detection by the network-side device. 
     Optionally, the uplink transmission includes: 
     uplink transmission generated on a carrier with the smallest carrier index among a plurality of carriers in a case that the plurality of carriers are configured with configured grants; or 
     uplink transmission generated on a target configured grant of one carrier in a case that the one carrier is configured with a plurality of configured grants. 
     It should be noted that the uplink transmission generated herein may be uplink transmission generated in a case that data transmission is performed or no data transmission is performed on the carrier. 
     The target configured grant may include at least one of the following configured grants of the one carrier: 
     a configured grant with the smallest index, a configured grant with the earliest transmission start time, or a configured grant with the latest transmission start time. 
     In this implementation, if the terminal configures configured grants on a plurality of carriers, the uplink transmission can be generated on the carrier with the smallest carrier index value, for example, a CG PUSCH. In addition, if the terminal configures a plurality of configured grants on one carrier, the uplink transmission can be generated on at least one of a configured grant with the smallest index value, a configured grant with the earliest transmission start time, or a configured grant with the latest transmission start time, for example, a CG PUSCH. 
     In this embodiment of this application, in a case that the uplink control channel conflicts with the uplink data channel, multiplexing transmission is performed for the uplink control information and the uplink transmission, where the transmission resource of the uplink transmission and the transmission resource of the uplink control channel overlap, and the uplink transmission meets the preset condition. Because the uplink transmission meets the preset condition, the network-side device can obtain the uplink control information by detecting only the uplink transmission that meets the preset condition, to reduce complexity of blind detection by the network-side device.

     Optionally, in a case that the uplink data channel is a dynamic grant, the preset condition includes:
