Abstract

This application provides a method for configuring a transmission direction of a time-frequency resource, and an apparatus. A terminal device receives first configuration information sent by a first access network device and/or second configuration information sent by a second access network device, and transmits data based on the first configuration information and/or the second configuration information. The first configuration information includes configuration information of a transmission direction of the first access network device in at least one resource unit, the second configuration information includes configuration information of a transmission direction of the second access device in at least one resource unit, and the at least one resource unit includes at least one of a frequency domain unit, a time domain unit, and a space domain unit.
