Integrated circuit for random access method and apparatus

摘要

Integrated circuitry for use in a mobile radio station includes a receiver that receives control information and a data processor coupled to the receiver. The data processor provides a number of different sequences that are derived from a base sequence. The different derived sequences are respectively associated with different amounts of data or reception qualities, have different cyclic shifts, and are arranged in an increasing order of the cyclic shifts. The data processor randomly selects a sequence from a subset of the derived sequences. The subset of derived sequences depends on the control information.

1. Integrated circuitry comprising:
a receiver configured to receive control information, and a data processor, coupled to the receiver, configured to: provide a number of different sequences that are derived from base sequence, where different derived sequences are respectively associated with different amounts of data or reception qualities, have different cyclic shifts, and are arranged in an increasing order of the cyclic shifts, and randomly select a sequence from a subset of the derived sequences, wherein the subset of derived sequences depends on the control information.
