Abstract
In a wireless communication terminal that performs repetition transmission in which predetermined data is repeatedly transmitted, a wireless communication unit receives continuation information which is information on continuation of the repetition transmission before and after handover, and a control unit performs the repetition transmission after the handover based on the continuation information.
Claims16
A communication device that performs repetition transmission in which predetermined data is repeatedly transmitted, the communication device comprising:
- a wireless communication unit that receives continuation information which is information on continuation of the repetition transmission before and after handover of the communication device from a first base station device to a second base station device, wherein the continuation information includes request information requesting transmission of data identical to the predetermined data, which has been transmitted to the first base station device as a handover source before the handover, to the second base station device as a handover destination after the handover;
- and
- a control unit that continues the repetition transmission after the handover based on the continuation information by repeatedly transmitting, to the second base station device after the handover, the same predetermined data that have been repeatedly transmitted to the first base station device before the handover.
A base station device that communicates with a terminal device, which performs repetition transmission in which same data is repeatedly transmitted, the base station device comprising:
- a processor that generates continuation information which is information on continuation of the repetition transmission before and after handover of the terminal device from the base station device to a second base station device, based on which the terminal device repeatedly transmits, to the second base station device after the handover, the same predetermined data that have been repeatedly transmitted to the base station device before the handover, wherein the continuation information includes request information requesting transmission of data identical to the predetermined data, which has been transmitted to the base station device as a handover source before the handover, to the second base station device as a handover destination after the handover;
- and
- a wireless communication module that transmits the continuation information to the terminal device.
A data transmission method of a communication device that performs repetition transmission in which identical data is repeatedly transmitted, the data transmission method comprising:
- receiving continuation information which is information on continuation of the repetition transmission before and after handover of the communication device from a first base station device to a second base station device, wherein the continuation information includes request information requesting transmission of data identical to the predetermined data, which has been transmitted to the first base station device as a handover source before the handover, to the second base station device as a handover destination after the handover;
- and
- continuing the repetition transmission after the handover based on the continuation information by repeatedly transmitting, to the second base station device after the handover, the same predetermined data that have been repeatedly transmitted to the first base station device before the handover.
A communication method of a base station device that communicates with a terminal device which performs repetition transmission in which same data is repeatedly transmitted, the communication method comprising:
- generating continuation information which is information on continuation of the repetition transmission before and after handover of the terminal device from the base station device to a second base station device, based on which the terminal device repeatedly transmits, to the second base station device after the handover, the same predetermined data that have been repeatedly transmitted to the base station device before the handover, wherein the continuation information includes request information requesting transmission of data identical to the predetermined data, which has been transmitted to the base station device as a handover source before the handover, to the second base station device as a handover destination after the handover;
- and
- transmitting the continuation information to the terminal device.
