INTER-CELL INTERFERENCE CANCELLATION AT A MOBILE TERMINAL USING SIGNALED INFORMATION

Title:

INTER-CELL INTERFERENCE CANCELLATION AT A MOBILE TERMINAL USING SIGNALED INFORMATION

Document Type and Number:

WIPO Patent Application WO/2013/133747

Kind Code:

A3

Abstract:

In MU-MIMO scenarios, a target mobile terminal (220) can be exposed to data streams intended for other mobile terminals (222). If the target mobile terminal (220) is capable of interference cancellation, then a serving base station (210) can provide the target mobile terminal (220) with interference information so that the target mobile terminal (220) can efficiently cancel interferences due to these interfering data streams. The interference information includes one or more configuration information, each of which characterizes a related interfering data stream. The serving base station (210) provides the interference information over one or more radio resources that are exclusive allocated to the target mobile terminal (220) or are allocated for common listening. The serving base station (210) exchanges configuration information with neighboring base stations (212) over inter-BS links (250). The inter-BS links (250) use resources that are different from the radio resources used between the base stations (210, 212) and the mobile terminals (220, 222).
