    Abstract: A user equipment device operating in a cellular communications system includes a neighbor cell searcher configured to receive a first reference signal transmitted from a base station of a first cell of the cellular communications system and determine first channel information associated with the first cell, and receive a second reference signal transmitted from a base station of a second cell of the cellular communications system and determine second channel information associated with the second cell. A channel estimator is configured to generate correlations between times and frequencies associated with reception of the first reference signal and the second reference signal, and generate a channel estimate corresponding to the first reference signal based on the first channel information, the second channel information, and the correlations.

    Abstract: Some of the embodiments of the present disclosure provide a method for reducing interference feedback in a mobile device operating in a wireless system employing coordinated transmission. The method comprises the mobile device establishing a plurality of channels with a plurality of base stations. The plurality of base stations includes a serving base station and one or more interfering base stations. The method further comprises the mobile device reporting, to the serving base station, reduced feedback information including a vector approximation of a feedback matrix associated with an interfering channel established with an interfering base station. Other embodiments are also described and claimed.
