Abstract: Efficient encoding techniques are described for encoding resource allocation data to be signalled to a user device. In one encoding technique one or more frequency blocks are assigned to a user device and a plurality of resource blocks within the assigned frequency blocks are allocated to the user device. The assignment of frequency blocks and the resource block allocation are encoded separately and signalled to the user device. On receipt of the signalled information the user device interprets the frequency block assignment and uses this when interpreting the resource block allocation.

Abstract: The teachings herein present a method and apparatus that implement and use a factorized precoder structure that is advantageous in terms of performance and efficiency. In particular, the teachings presented herein disclose an underlying precoder structure that allows for certain codebook reuse across different transmission scenarios, including for transmission from a single Uniform Linear Array (ULA) of transmit antennas and transmission from cross-polarized subgroups of such antennas.
