1. An apparatus comprising:
a processor that:
maps, at the apparatus, each random access preamble sequence of a plurality of random access preamble sequences to corresponding indication information, wherein the indication information indicates at least two features selected from a group comprising a transmission resource assignment, a new data indicator, a transmit power control command, a modulation and coding scheme reference signal, and an acknowledgement and non-acknowledgement resource assignment corresponding to a respective random access preamble sequence of the plurality of random access preamble sequences;
generates a random access preamble sequence of the plurality of random access preamble sequences to establish a random access channel for an uplink transmission, wherein the random access preamble sequence implicitly indicates the indication information corresponding to the random access preamble sequence; and
a transmitter that:
transmits the random access preamble sequence to a base station; and
without receiving a response from the base station to the transmission of the random access preamble sequence, transmits uplink information separate from the random access preamble sequence based on the indication information in the random access preamble sequence.
