Further, the technical solutions of the embodiments of the present application can be applied to multi-carrier transmission system using the non-orthogonal multiple access technology, for example, Orthogonal Frequency Division Multiplexing (OFDM), Filter Bank Multi-Carrier (FBMC), Generalized Frequency Division Multiplexing (GFDM), Filtered-OFDM (F-OFDM) system, and the like, using the non-orthogonal multiple access technology. 
     A terminal device in the embodiments of the present application may refer to a User Equipment (UE), an access terminal, a subscriber unit, a subscriber station, a mobile radio station, a mobile station, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent or a user apparatus. An access terminal may be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with a wireless communication function, a computing device or other processing devices, in-vehicle devices, wearable devices connected to wireless modems, a terminal device in future 5G network or a terminal device in a future evolved Public Land Mobile Network (PLMN), and the like, which is not limited in the embodiments of the present application. 
     A network device in the embodiments of the present application may be a device for communicating with the terminal device, where the network device may be a base station (Base Transceiver Station, BTS) in GSM or CDMA, or may be a base station (NodeB, NB) in a WCDMA system, the network device may also be an evolutional base station (Evolutional NodeB, eNB or eNodeB) in the LTE system, and may also be a wireless controller in a Cloud Radio Access Network (CRAN) scenario, or the network device may be a relay station, an access point, an in-vehicle device, a wearable device, and a network device in the future 5G network or a network device in the future evolved PLMN network, which is not limited in the embodiments of the present application. 
       FIG.  1    is a schematic diagram of an application scenario according to an embodiment of the present application. A communication system in  FIG.  1    may include a terminal device  10  and a network device  20 . The network device  20  is configured to provide communication services for the terminal device  10  and access a core network. The terminal device  10  accesses the network by searching for a synchronization signal, a broadcast signal, and the like sent by the network device  20 , thereby performing communication with the network. Arrows shown in  FIG.  1    may represent uplink/downlink transmissions through a cellular link between the terminal device  10  and the network device  20 . 
     SPS is different from dynamic scheduling in that it can semi-persistently configure a radio resource and periodically allocate the resource to a fixed UE. Briefly, once a resource in a scheduling unit is allocated to a UE by an eNodeB, the UE can receive or send data on a fixed resource in each scheduling unit. The SPS does not need to send Downlink Control Information (DCI) to the UE in each scheduling unit, thus reducing overhead of control signaling. 
     In the LTE, the SPS resource allocated by the network device to the terminal device covers an entire system bandwidth. In NR, a system bandwidth supported by the terminal is much larger than the maximum system bandwidth of 20 MHz supported by the terminal in the LTE. For some terminals, due to limited capabilities, it is not always possible to support the full system bandwidth. In order to improve scheduling efficiency, a concept of BWP is introduced in the NR, and BWP is a concept of frequency domain dimension. Different BWPs may be different in at least one of the following parameters: numerology, a center frequency point, and a bandwidth. In a RRC connection state, the network can configure one or more BWPs for the terminal. At one point in time, the terminal can only support one activated BWP. The so-called activation of a BWP means that the terminal can receive a signal in a frequency band specified by a BWP, the signal including data transmission, a system message, and the like. 
     Since different BWPs have different frequency bands, the SPS resource allocated by the network is of course not applicable to all BWPs. Therefore, the corresponding SPS resource should be respectively allocated for each BWP. When a certain BWP is activated, how the terminal device obtains the SPS resource within the BWP is a problem that needs to be solved. 
       FIG.  2    shows a schematic block diagram of a method  100  for transmitting data in an embodiment of the present application. As shown in  FIG.  2   , the method  100  includes parts or all of the following contents: 
     S 110 , a terminal device receives first indication information sent by a network device, where the first indication information indicates that data is capable of being transmitted on a semi-persistent scheduling resource within a first bandwidth part BWP of at least one BWP and where the first BWP is in an active state; 
     S 120 , the terminal device determines the semi-persistent scheduling resource within the first BWP according to the first indication information; and 
     S 130 , the terminal device performs data transmission on the semi-persistent scheduling resource within the first BWP with the network device. 
     Specifically, the network device may configure one or more BWPs for the terminal device, and can configure different SPS resources for each BWP. For example, at least one of a frequency domain location of the SPS resource or a period of the SPS resource may be configured under each BWP. When the terminal device determines which BWP is in the active state, the network device may send trigger information to the terminal device to trigger the terminal device to determine a SPS resource within a corresponding BWP. The trigger information is namely the above indication information, which may be configured to activate the SPS resource within the BWP, or configured to inform the terminal device that data is capable of being transmitted on the SPS resource within the BWP. The terminal device obtains location information of the SPS resource within the BWP according to the trigger information, and then the terminal device is capable of receiving or sending data on the SPS resource. 
     Therefore, according to the method for transmitting data in the embodiment of the present application, in a case that a BWP is activated, the obtaining of the SPS resource under the BWP is triggered by the network device, which is beneficial to improving the accuracy of data transmission. 
     In an embodiment of the present application, the at least one BWP is a plurality of BWPs, and the first indication information further indicates that an operating BWP of the terminal device is switched from a second BWP of the plurality of BWPs to the first BWP. 
     In an embodiment of the present application, the at least one BWP is a plurality of BWPs, and before the terminal device receives the first indication information sent by the network device, the method further includes: the terminal device receives second indication information sent by the network device, where the second indication information indicates that an operating BWP of the terminal device is switched from a second BWP of the plurality of BWPs to the first BWP. 
     When the network device configures a plurality of BWPs for the terminal device, the network device may cause the terminal device to switch between a plurality of BWPs by sending an instruction to the terminal device, that is, by deactivating the current one BWP and activating another BWP. 
     Such indication manner may include RRC signaling, Downlink Control Information (DCI), or Media Access Control (MAC) signaling, and the like. Alternatively, the terminal device can also be configured with a timer, that is, it can be switched between different BWPs according to a certain time rule. When the network device indicates a switch to the terminal device, that is, information of a BWP to be activated may be informed, for example, the information may be an identifier, or may be at least one of a central frequency point, bandwidth information, or numerology of the BWP to be activated. 
     The indication information for triggering the terminal device to obtain the SPS resource within the corresponding BWP may multiplex the indication information for activating the BWP, or may be different bits in a piece of information with respect to the indication information for activating the BWP, or may be two separate information, which is not limited in the embodiments of the present application. 
     When the indication information for triggering the terminal device to obtain the SPS resource in the corresponding BWP is different from the indication information for activating the BWP, the two indication information may be sent to the terminal device through the above RRC signaling, DCI, or MAC signaling. 
     In an embodiment of the present application, after the terminal device receives the second indication information and before the terminal device receives the first indication information, the semi-persistent scheduling resource within the first BWP is in an inactive state. 
     Each time the terminal device activates one BWP, the data can be transmitted on the SPS resource in the corresponding BWP only in a case that the first indication information is received. Otherwise, when activating a BWP, the terminal device can consider that the SPS resource within the BWP is prohibited from use, that is, in the inactive state. 
     When the terminal device switches from one BWP to another BWP, the SPS resource within a previous BWP may be in the active state, that is, the data is capable of being transmitted on the SPS resource within the previous BWP, and the SPS resource in the previous BWP may also be in the inactive state. In other words, when an operating BWP of the terminal device is the previous BWP, the SPS resource in the previous BWP is prohibited from transmitting data. 
     In an embodiment of the present application, the terminal device determining the semi-persistent scheduling resource within the first BWP according to the first indication information includes the terminal device determining a frequency domain location of the semi-persistent scheduling resource within the first BWP according to the first indication information; and where the terminal device performing the data transmission on the semi-persistent scheduling resource within the first BWP includes: the terminal device performing the data transmission on the semi-persistent scheduling resource within the first BWP with the network device at a pre-configured period. 
     As mentioned above, the SPS resource is a semi-persistently configured fixed frequency band, and the fixed frequency band resource is periodically allocated to a fixed UE. Then, in an embodiment of the present application, after the terminal device determines the current operating BWP, the terminal device may first determine the frequency domain location of the SPS resource corresponding to the operating BWP, and then the terminal device may periodically perform data transmission on the SPS resource. The period may be configured by the network device or may be pre-stored in the terminal device according to a protocol agreement. 
     In an embodiment of the present application, the SPS resource may be an uplink resource, that is, a resource configured to transmit uplink data, or may be a downlink resource, that is, a resource configured to transmit downlink data. 
     In an embodiment of the present application, the determining, by the terminal device, the semi-persistent scheduling resource within the first BWP according to the first indication information includes: determining the semi-persistent scheduling resource within the first BWP according to a pre-configuration by the network device after receiving the first indication information sent by the network device. 
     Specifically, the network device may configure the SPS resources within the different BWPs in advance, for example, may configure a period, a frequency domain resource, or may also be various parameters such as Modulation and Coding Scheme (MCS) for transmitting data, and the like, for the terminal device through a RRC signaling.
