A wireless telecommunication system comprises a base station arranged to communicate messages to one or more terminal devices over a radio interface. The radio interface has a radio frame structure comprising a plurality of subframes, wherein a message may be transmitted in accordance with a first transmission scheme using transmission resources in a first number of radio subframes (e.g. one subframe) or transmitted in accordance with a second transmission scheme using transmission resources in a second number of radio subframes (e.g. with repeat transmissions in a plurality of subframes). The message is transmitted in association with an identifier to indicate a terminal device to which the message is addressed. A characteristic for the identifier, for example a value or control region search space for the identifier, is dependent on whether the message is to be transmitted in accordance with the first transmission scheme or the second transmission scheme. A terminal device to which the message is addressed determines the transmission scheme from the characteristic of the identifier and receives the message accordingly.
A method of operating a base station for communicating a message to one or more terminal devices in a wireless telecommunications system over a radio interface having a radio frame structure comprising a plurality of subframes, wherein the message may be transmitted in accordance with a first transmission scheme using transmission resources in a first number of radio subframes or transmitted in accordance with a second transmission scheme using transmission resources in a second number of radio subframes, wherein the second number is greater than the first number, wherein the one or more terminal devices in the wireless telecommunications system comprise a first set of terminal devices and a second set of terminal devices, and wherein the message is transmitted in accordance with the first transmission scheme or the second transmission scheme in dependence on whether the terminal device to which the message is to be transmitted is a member of the first set of terminal devices or the second set of terminal devices, wherein the first transmission scheme comprises a first number of repetitions and the second transmission scheme comprises a second number of repetitions different from the first number of repetitions.
A base station for communicating a message to one or more terminal devices in a wireless telecommunications system over a radio interface having a radio frame structure comprising a plurality of subframes, wherein the base station comprises a controller unit and a transceiver unit configured to operate together such that the message may be transmitted in accordance with a first transmission scheme using transmission resources in a first number of radio subframes or transmitted in accordance with a second transmission scheme using transmission resources in a second number of radio subframes, wherein the second number is greater than the first number, wherein the one or more terminal devices in the wireless telecommunications system comprise a first set of terminal devices and a second set of terminal devices, and wherein the message is transmitted in accordance with the first transmission scheme or the second transmission scheme in dependence on whether a terminal device to which the message is to be transmitted is a member of the first set of terminal devices or the second set of terminal devices, wherein the first transmission scheme comprises a first number of repetitions and the second transmission scheme comprises a second number of repetitions different from the first number of repetitions.
Circuitry for a base station communicating a message to one or more terminal devices in a wireless telecommunications system over a radio interface having a radio frame structure comprising a plurality of subframes, wherein the circuitry comprises a controller element and a transceiver element configured to operate together such that the message may be transmitted in accordance with a first transmission scheme using transmission resources in a first number of radio subframes or transmitted in accordance with a second transmission scheme using transmission resources in a second number of radio subframes, wherein the second number is greater than the first number, wherein the one or more terminal devices in the wireless telecommunications system comprise a first set of terminal devices and a second set of terminal devices, and wherein the message is transmitted in accordance with the first transmission scheme or the second transmission scheme in dependence on whether a terminal device to which the message is to be transmitted is a member of the first set of terminal devices or the second set of terminal devices, wherein the first transmission scheme comprises a first number of repetitions and the second transmission scheme comprises a second number of repetitions different from the first number of repetitions.
A method of operating a terminal device for receiving a message from a base station in a wireless telecommunications system over a radio interface having a radio frame structure comprising a plurality of subframes, wherein the message may be transmitted by the base station in accordance with a first transmission scheme using transmission resources in a first number of radio subframes or transmitted by the base station in accordance with a second transmission scheme using transmission resources in a second number of radio subframes, wherein the second number is greater than the first number, and wherein a plurality of terminal devices in the wireless telecommunications system comprise a first set of terminal devices and a second set of terminal devices, and wherein the message is transmitted in accordance with the first transmission scheme or the second transmission scheme in dependence on whether the terminal device to which the message is to be transmitted is a member of the first set of terminal devices or the second set of terminal devices, wherein the first transmission scheme comprises a first number of repetitions and the second transmission scheme comprises a second number of repetitions different from the first number of repetitions.
