Abstract: An apparatus and method providing feedback on channel conditions in a wireless telecommunications system including a base station to communicate with plural terminals device using frequencies spanning a system frequency bandwidth. At least one terminal device is a reduced capability terminal device including a tuneable transceiver configured to receive downlink transmissions from the base station using only a restricted frequency bandwidth smaller than and within the system frequency bandwidth. The reduced capability terminal device is configured to communicate information derived from measurements of channel conditions to the base station. The information may include an indication of measured channel conditions for different frequency locations, or an indication of one or more frequency locations for which corresponding measurement of channel conditions meet a pre-defined selection criterion. The base station subsequently schedules downlink transmissions for the terminal device in a manner that takes account of the information received from the terminal device.

Abstract: A method of operating first and second terminal devices for transmitting data in a device-to-device communication mode in a wireless telecommunications system supporting communications on a first carrier operating over a first frequency band and a second carrier operating over a second frequency band. The first terminal device transmits control signalling on the first carrier and this is received by the second terminal device. The control signalling comprises an indication of an allocation of radio resource blocks on the second carrier to be used for transmitting user-plane data from the first terminal device to the second terminal device. The first terminal device then proceeds to transmit the user-plane data to the second terminal device on the second carrier using the radio resource blocks on the second carrier identified by the control signalling. The control signalling may also provide an indication of an allocation of radio resource blocks on the first carrier to be used for transmitting user-plane data to the second terminal device.

Abstract: A method of reducing interference comprises estimating an interference level in a mobile network. In the event that the interference level is detected as being above a satisfactory threshold, the method comprises selecting an infrastructure unit of one or more infrastructure units which is currently operating as one of a base station or an uplink and downlink relay node configured to relay uplink and downlink transmissions, and configuring the infrastructure unit to operate as an uplink relay node such that it does not send downlink signals. In the event that the interference level is detected as being below a satisfactory threshold, the method comprises selecting an infrastructure unit currently operating as an uplink relay node such that it does not send downlink signals, and configuring the infrastructure unit to operate as one of a base station or an uplink and downlink relay node configured to relay uplink and downlink transmissions.

Abstract: A method of operating a first terminal device to transmit data to a second terminal device by performing device-to-device communication includes selecting radio resources, on which to transmit the data based on a priority status associated with the data, whereby certain radio resource are reserved for use in association with data classified as high priority. A method of operating the second terminal device to receive data from the first terminal device includes: receiving data from the first terminal device using the selected radio resources; determining if another terminal device is transmitting data on a radio resource which is not selected for transmitting data by the first terminal device and which is reserved for transmitting data classified as having a high priority; and, if so, stopping reception of data from the first terminal device on the selected radio resources and instead seeking to receive further transmissions from the other terminal device.

Abstract: A wireless telecommunications system including a base station and a terminal device and employing a radio interface having a downlink radio frame structure including radio subframes including an arrangement of reference symbols for channel estimation. The base station is configured to determine a period of time for which certain terminal device specific data are not scheduled for transmission to the terminal device and to communicate this information to the terminal device through selective suppression of at least one reference symbol. Different reference symbol(s) may be suppressed to indicate different periods of time. The terminal device is configured to monitor the reference symbols transmitted by a base station to identify where reference symbols are suppressed, to determine a period of time for which the terminal device is not expected to receive certain types of data and enter a reduced activity mode for that period to conserve processing and power resources.

Abstract: A method of paging in a wireless telecommunications system. A core network element selects a base station from plural base stations including a tracking area to have primary responsibility for paging a terminal device and conveys an indication of the terminal device to the selected base station. Each base station maintains a paging database identifying one or more terminal devices for which it has a responsibility for paging. When a terminal device is to be paged, the core network element transmits a paging request to the plural base stations including the tracking area. The respective base stations then determine whether to onward transmit a paging message for the terminal device based on a comparison between an identifier for the terminal device being paged with entries in their paging database, and if the comparison indicates it has responsibility for paging the terminal device, it will transmit a paging message accordingly.

Abstract: A wireless telecommunication system includes base stations for communicating with terminal devices. One or more base stations support a power boost operating mode in which a base station's available transmission power is concentrated in a subset of its available transmission resources to provide enhanced transmission powers as compared to transmission powers on these transmission resources when the base station is not operating in the power boost mode. A base station establishes an extent to which one or more base stations in the wireless telecommunications system support the power boost operating mode conveys an indication of this to a terminal device. The terminal device receives the indication and uses the corresponding information to control its acquisition of a base station of the wireless telecommunication system, for example by taking account of which base stations support power boosting and/or when power boosting is supported during a cell attach procedure.
