Abstract
A plurality of the same signals to be repetitively transmitted over multiple subframes are multiplied, in each subframe, by one of components of one sequence of a plurality of orthogonal sequences orthogonal to each other thereby generating a transmission signal. The generated transmission signal is transmitted.
Claims20
A terminal comprising:
- a generator that generates a transmission signal repetitively over multiple subframes by multiplying, in each subframe, a signal by one of components of one sequence of a plurality of first sequences orthogonal to each other;
- and
- a transmitter that transmits the transmission signal over the multiple subframes,
- wherein
- the plurality of first sequences are respectively associated with terminal IDs, and
- the generator sets, as the one sequence used by the terminal, a sequence included in the plurality of first sequences and corresponding to a terminal ID indicated by a base station.

A transmission method comprising:
- generating a transmission signal repetitively over multiple subframes by multiplying, in each subframe, a signal by one of components of one sequence of a plurality of first sequences orthogonal to each other;
- and
- transmitting the transmission signal over the multiple subframes,
- wherein
- the plurality of first sequences are respectively associated with terminal IDs, and

A base station comprising:
- a receiver that receives a signal repetitively transmitted over multiple subframes from a terminal, the signal having been multiplied by the terminal, in each subframe, by one of components of one sequence of a plurality of first sequences orthogonal to each other;
- and
- a combiner that generates a combined signal by combining signals of the multiple subframes using the one sequence,
- wherein
- the plurality of first sequences are respectively associated with terminal IDs, and
- the one sequence used by the terminal and used in the generating step is a sequence included in the plurality of first sequences and corresponding to a terminal ID notified to the terminal by the base station.

A reception method comprising:
- receiving a signal repetitively transmitted over multiple subframes from a terminal, the signal having been multiplied by the terminal, in each subframe, by one of components of one sequence of a plurality of first sequences orthogonal to each other;
- and
- generating a combined signal by combining signals of the multiple subframes using the one sequence,
- wherein
- the plurality of first sequences are respectively associated with terminal IDs, and
- the one sequence used by the terminal and used in the generating step is a sequence included in the plurality of first sequences and corresponding to a terminal ID associated with the terminal.
