Abstract
The disclosure relate to interference coordination in wireless communications. A first level station can obtain information for interference coordination with a second level station to protect the second level station from interference in arrangement where the second level station provides a smaller coverage area than the first level station and is at least partially located in the area of the first level station. Use of directional antenna beams by the first level station and/or communications by the second level station can then be controlled accordingly.
Claims21
A method for interference coordination in wireless communications, comprising:
- obtaining information by a first level station for interference coordination with a second level station to protect the second level station from interference by the first level station, the second level station providing a smaller coverage area than the first level station and being at least partially located in the area of the first level station, and
- controlling use of directional antenna beams by the first level station according to the information.
A method for interference coordination in wireless communications, comprising:
- sending and/or receiving information by a second level station for interference coordination by means of directional antenna beams by a first level station, the second level station providing a smaller coverage area than the first level station and being at least partially located in the area of the first level station, the information regarding interference by the first level station in the area of the second level station, and
- controlling communication by the second level station according to the information.
An apparatus for a first level station in a wireless system where at least a second level station is provided, the second level station providing a smaller coverage area than the first level station and being at least partially located in the area of the first level station, the apparatus comprising at least one processor, and at least one memory including computer program code, wherein the at least one memory and the computer program code are configured, with the at least one processor, to
- obtain information by the first level station for interference coordination with the second level station to protect the second level station from interference by the first level station, and
- control use of directional antenna beams by the first level station according to the information.
An apparatus for a second level station in a wireless system where at least a first level station is provided, the second level station providing a smaller coverage area than the first level station and being at least partially located in the area of the first level station, the apparatus comprising at least one processor, and at least one memory including computer program code, wherein the at least one memory and the computer program code are configured, with the at least one processor, to
- cause sending and/or receiving of information by the second level station for interference coordination by means of directional antenna beams by first level station, the information regarding interference by the first level station in the area of the second level station, and
- control communication by the second level station according to the information.
