Abstract
A wireless telecommunications system including at least one base station, a first terminal device and a second terminal device, wherein the first terminal device is a terminal device of a first type and the second terminal device is a terminal device of a second type, the second type being different from the first type, and wherein the at least one base station is configured to communicate data which is specific to the first terminal device in a synchronous manner and to communicate data which is specific to the second terminal device in a non-synchronous manner.
Claims20
A terminal device for communicating in a wireless telecommunications system, the terminal device being not synchronized to a radio frame structure, the terminal device comprising:
- circuitry configured to:
- receive a transmission from the wireless telecommunications system in a non-synchronous manner;
- search the transmission for a predefined signature sequence, the predefined signature sequence being associated with data that is specific to the terminal device;
- determine, based on whether the predefined signature sequence is found in the transmission, whether the transmission is intended for the terminal device;
- and
- extract, when the transmission is determined to be intended for the terminal device, the data that is specific to the terminal device from the transmission.
A method for communicating in a wireless telecommunication system, the terminal device being not synchronized to a radio frame structure, the method comprising:
- receiving, by a terminal device, a transmission from the wireless telecommunications system in a non-synchronous manner;
- searching the transmission for a predefined signature sequence, the predefined signature sequence being associated with data that is specific to the terminal device;
- determining, by the terminal device and based on whether the predefined signature sequence is found in the transmission, whether the transmission is intended for the terminal device;
- and
- extracting, by the terminal device when the transmission is determined to be intended for the terminal device, the data that is specific to the terminal device from the transmission.
An integrated circuit for use in a terminal device that communicates in a wireless telecommunications system, the terminal device being not synchronized to a radio frame structure, the integrated circuit comprising:
- circuitry configured to cause the terminal device to:
- receive a transmission from the wireless telecommunications system in a non-synchronous manner;
- search the transmission for a predefined signature sequence, the predefined signature sequence being associated with data that is specific to the terminal device;
- determine, based on whether the predefined signature sequence is found in the transmission, whether the transmission is intended for the terminal device;
- and
- extract, when the transmission is determined to be intended for the terminal device, the data that is specific to the terminal device from the transmission.
