Method and apparatus for reference signal selection in a cellular system
First Claim
1. A method for selecting a reference signal to be transmitted by a cell of a multi-cell wireless communication system, the method comprising the steps of:
- selecting, by the cell, a first reference signal used to identify the cell from a predetermined limited set of reference signals for transmission on a first channel resource;
transmitting the first reference signal on the first channel resource;
selecting, by the cell, a second reference signal used to identify the cell from the predetermined limited set of reference signals for transmission on a second channel resource; and
transmitting the second reference signal on the second channel resource.

Abstract
In a wireless communication system, a method and apparatus for reference signal selection is disclosed. In accordance with the preferred embodiment of the present invention, a first reference signal in a first cell is pseudo-randomly selected from a predetermined limited set of reference signals for transmission on a first channel resource. A second reference signal in the cell is pseudo-randomly selected from the predetermined limited set of reference signals for transmission on a second channel resource, where the predetermined limited set of reference signals is common among the first cell and at least a second cell.
