Abstract
A transmission angle control device in a wireless communication system based on a TDD scheme includes: an interference signal detection unit that detects a level of interference on a second base station caused by a signal transmitted by a first base station based on a received signal received from the second base station and that outputs the interference level as an interference information signal; and a transmission angle determining unit that adjusts a transmission angle of a signal transmitted by the first base station in a vertical direction according to the interference information signal.

A transmission angle control device in a wireless communication system based on a TDD (Time Division Duplex) scheme, the device comprising:
- an interference signal detection unit that detects a level of interference on a second base station caused by a signal transmitted by a first base station based on a received signal received from the second base station and that outputs the interference level as an interference information signal;
- and
- a transmission angle determining unit that adjusts a transmission angle of a signal transmitted by the first base station in a vertical direction according to the interference information signal.
A transmission angle control method in a wireless communication system based on a TDD (Time Division Duplex) scheme, the method comprising:
- detecting a level of interference on a second base station caused by a signal transmitted by a first base station based on a received signal received from the second base station;
- and
- adjusting a transmission angle of a signal transmitted by the first base station in a vertical direction according to the interference level.
A non-transitory computer-readable recording medium, storing a program that causes a computer provided in a first base station in a wireless communication system based on a TDD (Time Division Duplex) scheme to execute:
- detecting a level of interference on a second base station caused by a signal transmitted by the first base station based on a received signal received from the second base station;
- and
- adjusting a transmission angle of a signal transmitted by the first base station in a vertical direction according to the interference level.
