INDICATING E-DCH RESOURCES FOR E-RACH. |
摘要 |
<p>In UMTS WCDMA a new RACH-based uplink is being discussed. The request for uplink transmission resource is made using a mechanism based on the conventional RACH. The main difference from the conventional RACH is that the data transmission uses a high-speed uplink packet data channel, known as Enhanced Dedicated Channel (E-DCH), instead of a single short message associated directly with the RACH preamble. One proposed scheme for indicating the E-DCH resources to be used creates a link between the values of each of a group of multiple signatures sent on the AICH (to acknowledge the E-RACH access) and a specific set of E-DCH parameters defined in a table. We propose to signal the set of resources to be used independently from acknowledging the E-RACH access. One possible method is to transmit information in the unused portion of the AICH (corresponding to 1024 chips every slot) indicating the resource set.</p> |
