The at least one user-specific RS is configured to be transmitted in a pattern. The at least one user-specific RS is transmitted to a UE. The pattern of the at least one user-specific RS includes at least one over-the-edge RS transmitted outside of the PRB allocation. A UE receives at least one user-specific RS in a pattern, and performs channel estimation based on the at least one user-specific RS. At least part of the at least one user-specific RS is in a PRB allocation of the UE and the pattern of the at least one user-specific RS in - cludes at least one over-the-edge RS received outside of the PRB allocation of said UE. 111111111111110111011111111111010111110 011101111111111101111101111111110111111
