Abstract:
A method of operating a terminal device and network infrastructure equipment in a wireless telecommunications system for communicating on a primary cell supporting a primary component carrier on radio resources within a first frequency band and a secondary cell supporting a secondary component carrier on radio resources within a second frequency band. The infrastructure equipment establishes plural configuration settings for the secondary carrier based on measurements of radio usage in the second frequency band which are conveyed to the terminal device. The terminal device makes channel quality measurements for the secondary component carrier according to the different configuration settings and reports these to the infrastructure equipment. Based on these measurements of channel quality for the different configurations, the infrastructure equipment selects one of the configuration settings, and conveys an indication of this to the terminal device in association with an allocation of transmission resources on the secondary component carrier.
Abstract:
A method of operating a terminal device and a base station in a wireless telecommunications system to communicate with one another using a primary component carrier operating on radio resources within a first frequency band and a secondary component carrier operating on radio resources within a second frequency band. The terminal device makes measurements of radio usage in the second frequency band, e.g. by other devices which are not part of the wireless telecommunications system but which can also use radio resources within the second frequency band. The terminal device transmits an indication of the measurements to the base station, and on the basis if this the base station establishes a configuration setting for the secondary component carrier, for example in terms of frequency resources to use for the secondary component carrier. The configuration setting is associated with a validity period during which the base station communicates data to the terminal device using the primary component carrier and the secondary component carrier operating in accordance with its configuration setting. When the validity period expires, the terminal device again measures and reports on radio usage so the base station can determine an updated configuration setting for the secondary component carrier that takes account of any changes in radio usage during the validity period.
Abstract:
A network element forming a mobile communications network, and configured to provide a wireless access interface to one or more communications devices and to transmit downlink data to and receive uplink data from the communications devices via the wireless access interface. The downlink resources extend across a predetermined bandwidth and are time divided into plural timeframes. The network element includes a transmitter, and controller configured to control the transmitter to transmit control data to the communications devices in resources of a control channel formed from plural control channel modules formed from only part of the predetermined bandwidth and mutually exclusive from parts of the predetermined bandwidth from which the other control channel modules are formed. The plural control channel modules allow the control channel to be varied in bandwidth and adapted to the structure of the communications network, the communications devices being served and traffic conditions in the communications network.

Abstract:
A mobile communications network includes one or more network elements providing a wireless access interface for communications devices. The wireless access interface provides plural communications resource elements across a host frequency bandwidth, and includes, within the host frequency bandwidth, first communications resource elements within a first frequency bandwidth for allocation preferably to reduced capability devices to receive signals representing the data transmitted by the transmitter unit within the first bandwidth forming a first virtual carrier, the reduced capability devices each having a receiver bandwidth which is greater than or equal to the first frequency bandwidth but less than the host frequency bandwidth. Communications devices of different capabilities can be allocated communications resources within different frequency ranges according to their capability, which can relieve congestion on a centre frequency of communications resources in which communications devices with a minimum bandwidth capability must receive communications resources for receiving down link signals.

A communications device transmitting/receiving signals to/from a mobile communications network includes one or more network elements providing a wireless access interface for the communications device. The wireless access interface includes plural communications resource elements across a host frequency range of a host carrier, and a first section of the communications resources within a first frequency range for preferable allocation to reduced capability devices forming a first virtual carrier and a second section of the communications resources within a second frequency range for preferable allocation to the reduced capability devices forming a second virtual carrier. Each of the first and second frequency ranges is within the host frequency range. The communications device is configured with a reduced capability to receive the signals only within a frequency bandwidth less than the host frequency range and equal to at least one of the first frequency range or the second frequency range.
