Abstract: A method for wireless communication between user equipments (UEs) and a base station in a wireless communication system that supports a first UE using a single band and a second UE using multiple bands is provided. In the method, UE receives, from the base station, resource allocation information including information regarding a downlink component carrier (CC) and an uplink CC allocated to the UE, receives the allocated downlink CC, and transmits the allocated uplink CC by applying a cell ID thereto. The allocated downlink CC is one of downlink CCs to which different cell IDs are applied, pairs of CCs are predefined by associating uplink CCs respectively with downlink CCs in order to support the first UE. When the allocated downlink and uplink CCs do not belong to the pairs of CCs, the applied cell ID is a cell ID of a downlink CC that is paired with the allocated uplink CC in the predefined pairs of CCs.

Abstract: A method for efficiently transmitting and receiving control information through a Physical Downlink Control Channel (PDCCH) is provided. When a User Equipment (UE) receives control information through a PDCCH, the received control information is set to be decoded in units of search spaces, each having a specific start position in the specific subframe. Here, a modulo operation according to a predetermined first constant value (D) is performed on an input value to calculate a first result value, and a modulo operation according to a predetermined first variable value (C) corresponding to the number of candidate start positions that can be used as the specific start position is performed on the calculated first result value to calculate a second result value and an index position corresponding to the second result value is used as the specific start position. Transmitting control information in this manner enables a plurality of UEs to efficiently receive PDCCHs without collisions.

Abstract: A method of mapping symbols of a physical control format indicator channel (PCFICH) is described. A start position of a resource element to map the symbols for the PCFICH is determined by flooring a value, obtained by multiplying the number of resource blocks by a variable proportional to a symbol index for the PCFICH and then dividing the multiplied result by 2, wherein the resource blocks are transmitted in downlink. The symbols are mapped in the start position. Therefore, a problem of wasting resource elements or not being able to implement mapping can be solved by applying a simple mapping rule while mapping symbols of the PCFICH.
