Patent ID: 8824306

Claim:
A method of enabling auto-tuning of preamble sequences used during random access procedures, comprising: using an initial set of random access channel preamble sequences in one cell of a radio base station; identifying potentially conflicting random access channel preamble sequences between neighbours of said radio base station; collecting statistics on random access channel usage and information on the identified random access channel preamble sequences potentially conflicting between neighbours of said radio base station; optimizing said set of random access channel preamble sequences using said collected statistics; and replacing said initial set of random access channel preamble sequences with said optimized set of random access channel preamble (RACP) sequences, wherein the initial set of RACP sequences includes at least one RACP sequence that is not included in the optimized set of RACP sequences and said radio base station is configured such that only the optimized set of random access channel preamble sequences is used in said cell as a result of the replacing step being performed.
