20140086141 | WIRELESS COMMUNICATIONS SYSTEM AND METHOD - A wireless communications system includes a base station, a plurality of intermediate devices and a terminal device. The base station is operable to wirelessly transmit downlink signals to the terminal device, the downlink signals including terminal control signals identifying one of the intermediate devices as a target device to which the terminal device is to direct uplink signals intended for the base station. The terminal device wirelessly transmits the uplink signals to the base station via the intermediate device identified by the terminal control signals. In this way, downlink communications may be provided directly from the base station to the terminal device, including control signals which instruct the terminal device where to send uplink data. This enables the base station to directly control scheduling of uplink communications, and in particular to define the uplink route from the terminal device to the base station via one or more intermediate devices. | 03-27-2014 |
20140133335 | WIRELESS COMMUNICATIONS SYSTEM AND METHOD - A wireless communications system includes a base station, a plurality of intermediate devices, and a terminal device. Downlink communications may be provided directly from the base station to the terminal device, including control signals which instruct the terminal device where to send uplink data. This enables the base station to directly control scheduling of uplink communications, and in particular to define an uplink route from the terminal device to the base station via one or more intermediate devices. Power is conserved at the terminal device on the uplink because a lower power transmission can be used which although insufficient to reach the base station can reach the intermediate device. The terminal device is not required to determine the uplink path itself and therefore does not require complex, expensive, and power consuming control logic. | 05-15-2014 |
20140146738 | TELECOMMUNICATIONS APPARATUS AND METHODS - A method of communicating data between a base station and a plurality of terminal devices in a wireless telecommunications system is described. The method comprises transmitting data from the base station to the plurality of terminal devices in a multicast transmission and transmitting response signals from the terminal devices to the base station to indicate whether or not the respective terminal devices have successfully received the multicast transmission. The use of a multicast transmission provides an efficient mechanism for communicating the same data to a plurality of terminal device, for example as might be desired in a machine-type communication network. In combination with this, the use of individual response signals, such as ACK/NACK signalling, from the terminal devices allows the base station, or other entity, to track which terminal devices have indicated successful receipt of the multicast transmission, and to instigate an appropriate re-transmission protocol accordingly. | 05-29-2014 |

20140185575 | MOBILE COMMUNICATIONS SYSTEM, INFRASTRUCTURE EQUIPMENT, MOBILE COMMUNICATIONS TERMINAL AND METHOD TO COMMUNICATE USER DATA WITHIN AN UPLINK RANDOM ACCESS CHANNEL - A mobile communications terminal for communicating data to/from one or more base stations of a mobile communications network, the one or more base stations being arranged to provide a radio interface to communicate with mobile communications terminals. The mobile communications terminal being arranged to communicate with the one or more base stations via the radio interface, the communicating including using an uplink random access channel of the radio interface to transmit random access messages to the one or more base stations and communicating user data via the uplink random access channel by transmitting one or more of the random access messages at a selected timing within the uplink random access channel, the timing being selected by the first mobile communications terminal to represent at least part of the user data. | 07-03-2014 |
20140192764 | MOBILE COMMUNICATIONS SYSTEM, INFRASTRUCTURE EQUIPMENT, MOBILE COMMUNICATIONS TERMINAL AND METHOD TO COMMUNICATE USER DATA WITHIN AN UPLINK RANDOM ACCESS CHANNEL - A mobile communications system for communicating data to/from mobile communications terminals, the system including: one or more base stations configured to provide a radio interface to communicate data with mobile communications terminals; and one or more mobile communications terminals configured to communicate data with the one or more base stations via the radio interface, and wherein a mobile communication terminal is arranged to use an uplink random access channel to transmit random access messages to the one or more base stations. A first mobile communications terminal is configured to communicate user data via the uplink random access channel by transmitting one or more of the random access messages at a selected timing within the uplink random access channel, the timing being selected by the first mobile communications terminal to represent at least part of the user data. | 07-10-2014 |
20140194133 | ALLOCATING RESOURCES AND TRANSMITTING DATA IN MOBILE TELECOMMUNICATION SYSTEMS COMPRISING MACHINE TYPE COMMUNICATION APPLICATIONS - A method of communicating data in a wireless telecommunications system between plural base stations and plural terminal devices using plural Orthogonal Frequency Division Multiplex, OFDM, sub-carriers spanning a first frequency bandwidth. The method includes: communicating data between a first base station and a first terminal device using a first group of the OFDM sub-carriers distributed across the first frequency bandwidth, communicating data between a second base station, geographically separated from the first base station, and a second terminal device using a second group of the OFDM sub-carriers distributed across a second frequency bandwidth, and communicating control-plane data between the first base station and the first terminal device using a combination of the first and second groups of the OFDM sub-carriers. Guard regions may be provided in the frequency domain between frequencies of transmissions associated with the first base station and frequencies of transmissions associated with the second base station. | 07-10-2014 |
20150189660 | COMMUNICATIONS DEVICE AND METHOD - A mobile communications system communicates data to/from mobile communications devices, and provides a wireless access interface communicating data to/from the mobile communications devices, on a downlink first carrier providing plural communications resource elements across a first frequency range for communicating data, and within a second frequency range within and smaller than the first frequency range. The wireless access interface includes plural time divided sub-frames, each sub-frame including plural communications resource elements of the first frequency range and plural communications resource elements of the second frequency range. By arranging for a narrow band control channel to be within a virtual carrier and to communicate control information to both first full capability communications devices and second reduced capability communications devices, the second reduced capability devices can access the narrow band control channel which is shared with the first full-capability mobile devices, to make use of communications resources available to the communications system. | 07-02-2015 |
