CROSS-REFERENCE TO RELATED APPLICATIONS This is a continuation application of U.S. application Ser. No. 18/332,664, filed on Jun. 9, 2023, which is a continuation application of U.S. application Ser. No. 17/537,479, filed on Nov. 29, 2021, which is a continuation application of U.S. application Ser. No. 16/626,232, filed on Dec. 23, 2019, which is a national phase of International Patent Application No. PCT/CN2017/096910, filed on Aug. 10, 2017, the contents of which are hereby incorporated by reference in their entireties. TECHNICAL FIELD The disclosure relates to the field of communication, and more particularly, to a method for wireless communication, a network device and a terminal device. BACKGROUND In a new radio (NR) system, a physical downlink control channel (PDCCH) is transmitted in a control resource set (CORESET). At the present phase, a terminal device may uniformly monitor a CORESET to receive a PDCCH. However, such a CORESET monitoring mechanism is inflexible. In some circumstances, it is not required, for example, in a multi-beam system, for a terminal device to keep monitoring a CORESET at the same frequency. In such case, uniform monitoring for the CORESET may cause additional unnecessary complexity and power consumption of the terminal device. Therefore, how to flexibly configure a PDCCH monitoring manner is a problem urgent to be solved. SUMMARY A method for wireless communication, a network device and a terminal device are provided according to the embodiments of the disclosure. The network device may configure a time-domain position of a first resource for transmitting a PDCCH on time slot level, and may also configure a time-domain position of the first resource for transmitting the PDCCH on a symbol level. Therefore, a terminal device is not required to monitor the PDCCH on the first resource in each time slot, thereby reducing energy consumption of the terminal device. According to a first aspect, a method for wireless communication is provided according to an embodiment of the disclosure, which may include the following operations. Configuration information is sent to a terminal device. The configuration information is used to configure a time-domain position of a first resource, and the first resource is used to transmit a physical downlink control channel. The configuration information includes first configuration information and second configuration information. The first configuration information indicates at least one first time-domain unit, and each first time-domain unit includes the first resource. The second configuration information indicates at least one second time-domain unit in the first time-domain unit indicated by the first configuration information. Each second time-domain unit includes a part or all of the first resource. The physical downlink control channel is transmitted to the terminal device on the first resource. Optionally, the first time-domain unit is a time-domain unit on a time slot level, and the second time-domain unit is a time-domain unit on a symbol level. Optionally, a time-domain position, indicated by the configuration information, of the first resource may be a time-domain starting position of the first resource. Accordingly, in the method for wireless communication according to the embodiments of the disclosure, a network device configures the first resource for transmitting the physical downlink control channel at different levels through the first configuration information and the second configuration information, to implement a flexible PDCCH monitoring. Therefore, the terminal device is not required to monitor the PDCCH on the first resource in each time slot, thereby reducing energy consumption of the terminal device. Optionally, in an implementation of the first aspect, the first time-domain unit may include at least one time slot. Optionally, in an implementation of the first aspect, the second time-domain unit may include at least one symbol. Optionally, in an implementation of the first aspect, the first configuration information indicates an occurrence period of the first time-domain unit, or, the first configuration information indicates a time-domain position of the at least one first time-domain unit in a first time period. Optionally, in an implementation of the first aspect, in response to that the first configuration information indicates the at least one first time-domain unit through the time-domain position in the first time period, the time-domain position in the first time period may include a set of time-domain positions of all of the first time-domain unit in the first time period. Optionally, in an implementation of the first aspect, the second configuration information indicates an occurrence period of the second time-domain unit, or, the second configuration information indicates a time-domain position of the at least one second time-domain unit in the first time-domain unit.
