Abstract

Official abstract text for this publication.

A method is described for a specific user equipment (UE) to perform a random access to a Node-B within a cell in which a plurality of UEs are located together. The method includes receiving system information for at least one of a basic sequence index and a length of a zero correlation zone (ZCZ) from the Node-B, and transmitting a preamble sequence to the Node-B over a random access channel. The preamble sequence is generated from constant amplitude zero auto-correlation (CAZAC) sequences distinguishable by at least one of the basic sequence index and a length of a cyclic shift (CS) applied to the preamble sequence. The length of the CS applied to the preamble sequence is given by one among a plurality of application lengths determined based on the length of the ZCZ, wherein a number of the plurality of lengths are differently given based on a type of the specific UE, and wherein the system information is the same for all the UEs within the cell regardless of the types of UEs.

First claim

Opening claim text (preview).

What is claimed is: 1. A method for a specific user equipment (UE) to perform a random access to a Node-B within a cell in which a plurality of UEs are located together, the method comprising: receiving system information for at least one of a basic sequence index and a length of a zero correlation zone (ZCZ) from the Node-B; and transmitting a preamble sequence to the Node-B over a random access channel, wherein the preamble sequence is generated from constant amplitude zero…
