Method and apparatus for allocating time-frequency resource

Embodiments of the present application provide a method and an apparatus for allocating time-frequency resource in a frequency-band in a cell. The method includes: configuring three types of time-frequency resource including a first type of time-frequency resource in a first time period, a second type of time-frequency resource in a second time period, and a third type of time-frequency resource in a third time period; allocating the first type of time-frequency resource to one or more CCUs using the first RAT to perform data transmission and one or more CCUs using the second RAT to perform data transmission; allocating the second type of time-frequency resource to one or more CEU using the first RAT to perform data transmission; allocating the third type of time-frequency resource to one or more CEU using the second RAT to perform data transmission. The present application improves an overall throughput capacity in the cell.
