Abstract: An infrastructure equipment as part of a mobile communications network receives an indication that data is to be transmitted to one of communications devices. In response the infrastructure equipment transmits a first paging message to the communications device to indicate the communications device is to receive the data via a wireless access interface. If a response to the transmitted first paging message is not received within a predetermined time, then if the infrastructure equipment can use a power boosting mode, to transmit the first paging message with a boosted power, or if the infrastructure equipment cannot use a power boosted mode for transmitting, to transmit a second paging message to one or more communications apparatus which can operate as a relay node for the communications device. The second paging message identifies the relay node and the communications device for which the infrastructure equipment is to transmit the data.

Abstract: A method of operating a relay device to receive data from one or more terminal devices and relay the data to a base station in a wireless telecommunications system. The method includes receiving plural blocks of data from one or more terminal devices at different times. Each block of data is received in association with an indication of a time by which the block of data should be transmitted to the base station. The block of data are buffered at the relay node that determines earliest time by which one of the received blocks of data should be transmitted to the base station and transmits the plurality of blocks of data to the base station together in advance of this earliest time. The method reduces signalling overhead associated with transmissions from the relay device to the base station while helping to ensure data is not delayed at the relay node for longer than is acceptable for the data.

Abstract: A white space entity reserves spectrum in white space from a reservation system. Consequently, the white space entity may utilize television bands that are unused at a specified time period and geo-location in order to support different services such as wireless audio transmission, networking, video surveillance, and video conferencing. The white space entity requests reservation of spectrum resources from the reservation system by sending a reservation request. The request includes request parameters that may include geo-location, model number or manufacture code number, priority of entity, reservation time period, and maximum power level. The reservation system consequently verifies the request from the priority of the white space entity and the availability of white space spectrum for the desired time period. The white space entity then extracts confirmation parameters from a reservation confirmation message and subsequently transmits on white spectrum in accordance with the parameters.
