Abstract: A terminal random access procedure is improved by allowing a mobile terminal to correctly map signature indexes onto cyclic shifted Zadoff-Chu (ZC) sequences when the deployed cells support a high-speed mobility by informing a mobile terminal whether a cell supports high-speed mobility.

Abstract: A method for generating an uplink transmission burst includes using one or more symbols to define the uplink transmission burst, and forming a preamble portion and a payload portion for the uplink transmission burst. The preamble portion is formed using at least a portion of one or more of the symbols, such that the preamble portion includes a signature that is defined in a predetermined signature set. The payload portion is formed using at least a portion of one or more of the symbols. Typically, at least a portion of the preamble portion and at least a portion of the payload portion are formed using the same symbol.

Abstract: Methods for allocating and choosing dedicated signatures for random access are provided. Options for allocating dedicated signatures include allocating the dedicated signature from the unused space of the random signature root index when there is unused space and allocating more dedicated signatures from the same root index using the same time/frequency resources if additional signatures are needed, and reserving some preambles from the contention-based random access preambles from both sets of preambles. The present invention also proposes that the dedicated signatures be reserved in each of two sets of preambles.
