Abstract
Multi-beam uniform coverage in a coverage cell(s) in a wireless communications system (WCS) is provided. The WCS includes a number of wireless devices that are typically mounted on a fixed structure to provide coverage for user devices. Each wireless device includes one or more antenna arrays. Each antenna array is controlled via a set of codewords to form one or more RF beams to each cover a respective area in a coverage cell. The codewords are predetermined based on fairness and/or leakage constraints such that the RF beams can be formed in desired geometric shapes and steered toward desired directions to provide a uniform coverage in the coverage cell. By forming the RF beams based on the codewords predetermined based on fairness and/or leakage constraints, it is possible to ensure an equal RF power signal level inside the coverage cell and/or reduced power leakage outside the coverage cell.
