Abstract
This disclosure provides an information transmission method and apparatus and communication system. The method includes: receiving, by a user equipment, indication information transmitted by a base station indicating that the user equipment is capable of using the sidelink in a case where the air-interface link is incapable of normally transmitting data; and using the sidelink by the user equipment to perform data transmission with another user equipment in the case where the air-interface link is incapable of normally transmitting data. Hence, even if in a case where an air-interface link is unable to transmit data normally, data information may be transmitted successfully in other links.
Claims15
An information transmission method, applicable to a user equipment capable of using an air-interface link and a sidelink to perform data transmission with another user equipment, the information transmission method comprising:
- receiving, by the user equipment, indication information transmitted by a base station indicating that the user equipment is capable of using the sidelink in a case where the air-interface link is incapable of normally transmitting data;
- and
- using the sidelink by the user equipment to perform data transmission with the another user equipment in the case where the air-interface link is incapable of normally transmitting data.
An information transmission apparatus, configured in a user equipment capable of using an air-interface link and a sidelink to perform data transmission with another user equipment, the information transmission apparatus comprising:
- an indication receiving unit configured to receive indication information transmitted by a base station indicating that the user equipment is capable of using the sidelink in a case where the air-interface link is incapable of normally transmitting data;
- and
- a data transmitting unit configured to use the sidelink to perform data transmission with the another user equipment in the case where the air-interface link is incapable of normally transmitting data.
A communication system, comprising a first user equipment and a second user equipment capable of using an air-interface link and a sidelink to perform data transmission, the communication system further comprising:
- a base station configured to transmit indication information to the first user equipment indicating that the first user equipment is capable of using the sidelink in a case where the air-interface link is incapable of normally transmitting data;
- wherein, the first user equipment is configured to use the sidelink to perform data transmission with the second user equipment in the case where the air-interface link is incapable of normally transmitting data.
