EFFICIENT DIRECT ACCESS SIGNALING BASED ON AN EXPRESSION OF THE ALLOCATION OF A FIRST-TO-USE DIRECT ACCESS RESOURCE IN RELATION TO A UPLINK DATA TRANSFER BLOCK

摘要

The invention relates to devices and methods for transmitting data on a radio channel comprising to jointly encode (S4) a preamble format with a first random access configuration, forming an extended random access configuration. The extended random access configuration is then transmitted (S6) on the radio channel.
