Abstract
Official abstract text for this publication.
The present invention relates to a method and a communication network node for enabling automatic optimization of a random access preamble format usage in a communication network system. The network comprises the communication network node serving at least one cell to which user equipments are accessing. A random access preamble format is set for each cell and comprises a random access sequence length, T SEQ , and a random access preamble cyclic prefix length, T CP . First, the random access sequence length, T SEQ is selected and then the random access preamble cyclic prefix length, T CP is selected. Based on the selected random access sequence length, T SEQ and random access preamble cyclic prefix length, T CP , which random access preamble format to use in said cell is selected.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of enabling automatic optimization of a random access preamble format usage in a communication network system comprising a communication network node serving at least one cell to which user equipments are accessing, wherein a random access preamble format is set for said at least one cell and comprises a random access sequence length, T SEQ , and a random access preamble cyclic prefix length, T CP , the method comprising the steps of: the network node selecting said random access sequence length, T SEQ ; the network node selecting said random access preamble cyclic prefix length, T CP ; and based on said selected random access sequence length, T SEQ and random access preamble cyclic prefix length, T CP , the network node selecting which random access preamble format to use in said at least one cell, wherein said network node selects said random access preamble cyclic prefix length, T CP , based on said selected random access sequence length, T SEQ . 2. The method according to claim 1 , wherein said selected random access preamble format is selected from a plurality of predefined random access preamble formats.
