Abstract
The purpose of the invention is to realize appropriate random-access procedures in accordance with propagation delay between a terminal and a base station. A terminal (100) comprises a wireless transmission unit (104) that transmits random-access channel signals, and a control unit (108) that controls settings related to the transmission of signals in the random-access channel on the basis of availability of position information indicating the position of a communication partner of the terminal 100 and the position of the terminal 100.
Claims13
A transmission apparatus, comprising:
- transmission circuitry, which, in operation, transmits a signal of a random access channel;
- and
- control circuitry, which, in operation, controls a configuration relevant to the transmission of the signal in the random access channel based on availability of positional information, the positional information indicating a position of a communication partner of the transmission apparatus and a position of the transmission apparatus, wherein (i) when the positional information is unavailable, the control circuitry uses a first resource configuration in the random access channel and (ii) when the positional information is available, the control circuitry uses a second resource configuration in the random access channel.
A reception apparatus, comprising:
- reception circuitry, which, in operation, receives a signal of a random access channel;
- and
- control circuitry, which, in operation, controls reception of the signal based on a configuration relevant to a transmission of the signal in the random access channel, the configuration being associated with availability of positional information indicating a position of a communication partner and a position of the reception apparatus, wherein (i) when the positional information is unavailable, a first resource configuration is used in the random access channel and (ii) when the positional information is available, a second resource configuration is used in the random access channel.
A transmission method performed by a transmission apparatus, the transmission method comprising:
- controlling a configuration relevant to a transmission of a signal in a random access channel based on availability of positional information indicating a position of the transmission apparatus and a position of a communication partner of the transmission apparatus, wherein (i) when the positional information is unavailable, the a first resource configuration is used in the random access channel and (ii) when the positional information is available, a second resource configuration is used in the random access channel;
- and
- transmitting the signal of the random access channel.
A reception method by a reception apparatus, the reception method comprising:
- controlling reception of a signal based on a configuration relevant to a transmission of the signal in a random access channel, the configuration being associated with availability of positional information indicating a position of the reception apparatus and a position of a communication partner of the reception apparatus, wherein (i) when the positional information is unavailable, a first resource configuration is used in the random access channel and (ii) when the positional information is available, a second resource configuration is used in the random access channel;
- and
- receiving the signal of the random access channel.
