Claim Text:
1. A method of allocating root sequences to access nodes in a wireless communication system, comprising: determining a first coverage radius of a first access node and a first neighbor list, the first neighbor list comprising second access nodes which are each a neighbor access node of the first access node; determining a second coverage radius and a second neighbor list of each of the second access nodes; selecting an access node comprising a largest coverage radius from among the first access node and the second access nodes; calculating a number of root sequences required for the selected access node based on the coverage radius of the selected access node; and assigning root sequences to the selected access node according to the number of root sequences required such that root sequences are assigned to the selected access node prior to the access node that is not selected from among the first and second access nodes based on the largest coverage radius for the selected access node, wherein the assigned root sequences are used to generate preambles that wireless devices transmit to the selected access node to gain access to the wireless communication system.
