Method and device for allocating resources in multiple frequency band system

A user equipment (UE) for simultaneously receiving information from a plurality of frequency bands in an advanced wireless mobile communication system configured to use the plurality of frequency bands,

• wherein each frequency band in the plurality of frequency bands has a respective bandwidth for a conventional wireless communication system, the UE comprising:
• a radio frequency (RF) module;
• and a processor electrically connected to the RF module, wherein the processor receives and detects a resource indication value (RIV), indicating a start index (S) of consecutive virtual resource blocks (VRBs) allocated to the UE and a length (L) of the consecutive VRBs, through the RF module,
• wherein the detected RIV indicates that no resource is allocated to the UE within one frequency band in the plurality of frequency bands,
• wherein the detected RIV, indicating that no resource is allocated to the UE, is greater than a maximum value usable as an RIV allocated to other UE adapted for the conventional communication system and adapted for receiving information from only one frequency band.

A base station for simultaneously transmitting information from a plurality of frequency bands in an advanced wireless mobile communication system configured to use the plurality of frequency bands, wherein each frequency band in the plurality of frequency bands has a respective bandwidth for a conventional wireless communication system, the base station comprising:

• a radio frequency (RF) module;
• and
• a processor electrically connected to the RF module,
• wherein the processor transmits a resource indication value (RIV), indicating a start index (S) of consecutive virtual resource blocks (VRBs) allocated to a user equipment (UE) configured to simultaneously receiving information from the plurality of frequency bands and a length (L) of the consecutive VRBs, through the RF module,
• wherein the transmitted RIV indicates that no resource is allocated to the first UE within the one frequency band in the plurality of frequency bands, and
• wherein the transmitted RIV, indicating that no resource is allocated to the first UE, is greater than a maximum value usable as an RIV allocated to other UE adapted for the conventional communication system and adapted for receiving information from only one frequency band.
