Benefits of technology

[0017]The base station may be operable to transmit, using radio resources of the subordinate carrier, second acquisition information required for a terminal device of the second type to receive the subordinate carrier downlink and camp on to the subordinate carrier. The second acquisition information may be transmitted on predetermined radio resour

Problems solved by technology

While this solution is viable, the simple scheduling approach places some restrictions on the MTC subordinate carrier that can be realised.

Embodiment Construction

Network Structure

[0040]Embodiments of the present invention are described herein with particular reference to an example implementation in a wireless communication system having carriers based around the 3GPP Long Term Evolution (LTE) standard.

[0041]FIG. 1 schematically shows an example architecture of an LTE system. The LTE system is provided by a telecommunications network operator to allow parties to communicate. As shown in FIG. 1, mobile communications devices designated as user equipment (UE) 105 are arranged to communicate data to and from base stations (transceiver stations) 101 which are frequently referred to in LTE as E-UTRAN NodeBs (e-nodeB). Each of the base stations 101 comprises a transceiver unit 103 enabling communication of data to and from a plurality of mobile communication devices via a radio interface. The e-nodeBs 101 are connected to a serving gateway S-GW 104 and to a mobility management entity (MME) 107. The S-GW 104 is arranged to perform routing and manag...

Abstract

Wirelessly communicating with a first type of terminal device and a second type of terminal device is disclosed. The first type of terminal device may have a host carrier having radio resource segments distributed in time. Each radio resource segment may provide radio resources across a first frequency band. A second type of terminal device may also communicate, within a second frequency band, using a subordinate carrier comprising resources that are a subset of the host carrier radio resource segments. The second frequency band may be narrower than and contained within the first frequency band.

Description

FIELD OF THE INVENTION[0001]The present invention relates to wireless communications systems and methods, and in particular to a system, method, base station and terminal device for communicating using a subordinate carrier of a host carrier.BACKGROUND OF THE INVENTION[0002]Mobile communication systems have evolved over the past ten years or so from the GSM System (Global System for Mobile communications) to the 3G system and now include packet data communications as well as circuit switched communications. The third generation partnership project (3GPP) is developing a fourth generation mobile communication system referred to as Long Term Evolution (LTE) in which a core network part has been evolved to form a more simplified architecture based on a merging of components of earlier mobile radio network architectures and a radio access interface which is based on Orthogonal Frequency Division Multiplexing (OFDM) on the downlink and Single Carrier Frequency Division Multiple Access (S...
