Abstract
Official abstract text for this publication.
A method is provided for performing a random access procedure by a Node-B with a specific user equipment (UE) within a cell in which a plurality of UEs are located together. The Node-B transmits a random access procedure configuration including a basic sequence index related with a random access channel and zero correlation zone (ZCZ) configuration. The Node-B receives a random access preamble corresponding to the random access procedure configuration from the UE over the random access channel. A length of a cyclic part and a length of a sequence part of the random access preamble are differently given based on the random access procedure configuration. The random access preamble is generated from Constant Amplitude Zero Auto-Correlation (CAZAC) sequences based on the basic sequence index by applying a length of a cyclic shift according to the ZCZ configuration.
First claim
Opening claim text (preview).
What is claimed is: 1 . A method for performing a random access procedure by a Node-B with a specific user equipment (UE) within a cell in which a plurality of UEs are located together, the method comprising: transmitting, by the Node-B, a random access procedure configuration including a basic sequence index related with a random access channel and zero correlation zone (ZCZ) configuration; and receiving, by the Node-B, a random access preamble corresponding to the random access procedure configuration from the UE over the random access channel, wherein a length of a cyclic part and a length of a sequence part of the random access preamble are differently given based on the random access procedure configuration, wherein the random access preamble is generated from Constant Amplitude Zero Auto-Correlation (CAZAC) sequences based on the basic sequence index by applying a length of a cyclic shift according to the ZCZ configuration. 2 . The method of claim 1 , wherein the random access procedure configuration is based on a location of each UE within the cell. 3 . The method of claim 1 , wherein random access procedure configuration is transmitted over a broadcast channel (BCH). 4 . A Node-B for performing a random access procedure with a specific user equipment (UE) within a cell in which a plurality of UEs are located together, the Node-B comprising: a radio frequency (RF) unit; and a processor, wherein the processor is configured to: transmit, via the RF unit, a random access procedure configuration including a basic sequence index related with a random access channel and zero correlation zone (ZCZ) configuration; and receive, via the RF unit, a random access preamble corresponding to the random access procedure configuration from the UE over the random access channel, wherein a length of a cyclic part and a length of a sequence part of the random access preamble are differently given based on the random access procedure configuration, wherein the random access preamble is generated from Constant Amplitude Zero Auto-Correlation (CAZAC) sequences based on the basic sequence index by applying a length of a cyclic shift according to the ZCZ configuration.
