Abstract
A mobile communication system having a plurality of predefined cells that are mutually adjacent, comprises a spare cell that covers a boundary region of the plurality of predefined cells. The plurality of predefined cells use a predetermined frequency band and a first radio frame. The spare cell uses a second radio frame having a configuration different from the first radio frame so as to share the predetermined frequency band with the plurality of predefined cells through a time division.
Claims7
A mobile communication system having a plurality of predefined cells that are mutually adjacent, comprising:
- a spare cell that covers a boundary region of the plurality of predefined cells, wherein
- the plurality of predefined cells use a predetermined frequency band and a first radio frame, and
- the spare cell uses a second radio frame having a configuration different from the first radio frame so as to share the predetermined frequency band with the plurality of predefined cells through a time division.
A base station having a plurality of predefined cells that are mutually adjacent, comprising:
- a spare cell that covers a boundary region of the plurality of predefined cells, wherein
- the plurality of predefined cells use a predetermined frequency band and a first radio frame, and
- the spare cell uses a second radio frame having a configuration different from the first radio frame so as to share the predetermined frequency band with the plurality of predefined cells through a time division.
A user terminal in a mobile communication system having a plurality of predefined cells that are mutually adjacent, comprising:
- a control unit that controls to perform non-CoMP communication with a spare cell when the plurality of predefined cells and the spare cell that covers the boundary region belong to the same base station if the user terminal is positioned in the boundary region of the plurality of predefined cells, wherein
- the plurality of predefined cells use a predetermined frequency band and a first radio frame, and
- the spare cell uses a second radio frame having a configuration different from the first radio frame so as to share the predetermined frequency band with the plurality of predefined cells through a time division.
