Abstract
Random access technology is provided for establishing an individual channel between a radio communication terminal device and a base station device in a short time and a radio communication terminal device executing the random access method. A RACH sub-channel allocation unit allocates a transmission packet input from a replication unit to an arbitrary sub-carrier at the RACH arbitrary time slot at random. An allocation unit judges whether an overlap is generated in the allocation result obtained by the RACH sub-channel allocation unit.

Claim
1. A terminal apparatus comprising:
a receiver configured to receive information transmitted from a base station apparatus;
signal generating circuitry configured to generate, based on a predetermined number, a random access signal requesting service from the base station apparatus and comprised of data units which are successive in a time domain and which include a data unit and at least one duplication of the data unit,
wherein the data units are identical in number to the predetermined number; and
a transmitter configured to transmit the random access signal, from the terminal apparatus to the base station apparatus over a random access channel without waiting for a response from the base station apparatus to confirm whether the data unit or the duplication of the data unit has been received at the base station apparatus,
wherein the transmitted random access signal includes the data unit and the at least one duplication of the data unit in different time slots.
2. The terminal apparatus in claim 1, wherein the random access channel includes one or more of time slot, frequency, or spreading code.
3. The terminal apparatus in claim 1, wherein the random access channel is associated with radio resources, and wherein the transmitter is configured to transmit the random access signal using a radio resource selected at random from radio resource candidates.
4. The terminal apparatus in claim 1, wherein the receiver is configured to receive the predetermined number from the base station apparatus.
5. The terminal apparatus in claim 1, wherein the data unit and the duplication of the data unit are consecutive in the time domain.
6. The terminal apparatus in claim 1, wherein the transmitter is configured to transmit the random access signal on at least two consecutive time slots.
7. A method comprising:
receiving in a terminal information transmitted from a base station;
generating, based on a predetermined number, a random access signal requesting service for the terminal from the base station and comprised of data units which are successive in a time domain and which include a data unit and at least one duplication of the data unit,
wherein the data units are identical in number to the predetermined number; and
transmitting the random access signal, from the terminal apparatus to the base station over a random access channel without waiting for a response from the base station to confirm whether the data unit or the duplication of the data unit has been received at the base station,
wherein the transmitted random access signal includes the data unit and the at least one duplication of the data unit in different time slots.
8. The method in claim 7, wherein the random access channel includes one or more of time slot, frequency, or spreading code.
9. The method in claim 7, wherein the random access channel is associated with radio resources, and wherein the transmitter is configured to transmit the random access signal using a radio resource selected at random from radio resource candidates.
10. The method in claim 7, wherein the receiver is configured to receive the predetermined number from the base station.
11. The method in claim 7, wherein the data unit and the duplication of the data unit are consecutive in the time domain.
12. The method in claim 7, wherein the transmitter is configured to transmit the random access signal on at least two consecutive time slots.
