Abstract

Embodiments of the invention provide a flexible feedback framework that can operate in different scenarios, such as heterogeneous network deployments in which multiple transmit points, at least one containing a closely spaced antenna array group (CSAG), cooperate to provide macro diversity transmissions. Antenna information is sent to a UE, the antenna information comprising information indicating a grouping of antennae in a CSAG of one or more of the transmit points. For example, the antenna information may indicate for each CSAG, the antenna array block size, CSI-RS port configuration or/and whether the CSAG is a uniform linear array or a cross-polarized array. The UE takes into account the antenna information when selecting a precoding matrix W1 of a first codebook for a long-term precoder and also when selecting a precoding matrix W2 of a second codebook for a short-term precoder, also known as a sub-band precoder. Alternatively, components of the matrices may be selected rather than the matrices themselves, for example amplitude weight parameters, alpha, in the case of W1 or transmit point related combiners ck in the case of W2..
