Random access method, radio communication terminal device, receiving method, and base station apparatus |
摘要 |
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. |

1. A terminal apparatus comprising:
a receiver configured to receive control information transmitted from a base station apparatus; signal generating circuitry configured to generate, based on received information from the base station apparatus, a random access signal requesting service from the base station apparatus and including a number of duplicated random access sequences, where the number of duplicated random access sequences is based on the control information received in advance from the base station apparatus; 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 any of the duplicated random access sequences has been received at the base station apparatus. |
