FIELD: communication technology.
SUBSTANCE: invention relates to communication technology and can be used in wireless communication systems. Disclosed are a data transmission method, a terminal device and a network device. According to the method, the terminal determines the first part of the frequency bandwidth and the second part of the frequency bandwidth. The terminal device uses the first part of the bandwidth for data transmission and measurement for radio resource management (RRM) on the basis of a specific time domain resource and uses the second part of the bandwidth for data transmission on the basis of other time domain resources. Since the part of the frequency bandwidth that is used for data transmission and measurement for radio resource management is different from the part of the frequency bandwidth that is used only for data transmission, the terminal device can efficiently transmit data in the corresponding part of the frequency bandwidth and at the same time fulfill the measurement requirements for radio resource management.
EFFECT: invention improves data transmission efficiency.
