EPDCCH MOBILE COMMUNICATIONS SYSTEM NETWORK ELEMENT AND METHOD FOR RESOURCE ALLOCATION ON A VIRTUAL CARRIER FOR MACHINE-TYPE COMMUNICATIONS WITH A NARROW BAND EPDCCH

摘要

The mobile communication system communicates data to / from mobile communication devices. The mobile communication system provides a wireless access interface for communicating data to / from mobile communication devices, the wireless access interface providing a first carrier on the downlink, the first carrier for a first frequency range to communicate data. Providing a plurality of communication resource elements over a second frequency range within a first frequency range and less than the first frequency range. The wireless access interface provided by the base stations includes a plurality of time division subframes, each subframe including a plurality of communication resource elements in a first frequency range and a plurality of communication resource elements in a second frequency range, each of The subframe of is a first wideband control channel in a portion of each subframe having a bandwidth substantially corresponding to the first frequency range, and a bandwidth in the second portion of each subframe and less than the first wideband control channel. And a second narrowband control channel having a duration of the second narrowband control channel in the subframe is greater than the duration of the first wideband control channel in the subframe. The second narrowband control channel is configured to communicate control information to both the first mobile communication devices and the second mobile communication devices, and forms part of the plurality of communication resource elements of the second frequency range of the second carrier. . By configuring the narrowband control channel within the virtual carrier and enabling the control information to communicate to both the first full capacity mobile communication devices and the second reduced capacity mobile communication devices, the second reduced capacity devices It can access a narrowband control channel shared with the devices. This configuration allows more communication resources available to the communication system to be used.
