Title:

ENODEB RESTRICTED BANWIDTH AND POWER BOOST OPERATION TO SUPPORT MTC DEVICES

Document Type and Number:

WIPO Patent Application WO/2014/170230

Kind Code:

A3

Abstract:

A wireless telecommunication system comprises base stations for communicating with terminal devices having limited capabilities, e.g. MTC 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. In a similar manner base stations determine their support of virtual carrier operation, i.e. operation on a subset of the bandwidth defined in LTE, and signal their support to the terminals.
