The invention provides a
resource allocation control method, device and
system, wherein the method comprises the steps that: a primary
base station obtains indication information used for indicating transmitted buffer data; the primary
base station obtains the resource state indication information of the primary
base station and the resource state indication information of a secondary base
station; according to the resource state indication information of the primary base
station and the resource state indication information of the secondary base
station, the primary base station determines a first physical resource used for
processing the buffer data in the primary base station, and a second physical resource used for
processing the buffer data in the secondary base station; the primary base station notifies the secondary base station to reserve the second physical resource; therefore, the secondary base station sends a second scheduling command corresponding to the second physical resource to a terminal; and the primary base station sends a first scheduling command corresponding to the first physical resource to the terminal. By means of the
resource allocation control method, device and
system provided by the invention, the problem that the
resource utilization rate is relatively low due to the fact that carrier aggregation is carried out between cells in the related technology can be solved; and thus, the
resource utilization rate when carrier aggregation is carried out between the cells is increased.
