Method and device binding resource blocks used in wireless communications

A method and apparatus for binding resource block (RB) for a change in wireless communication bandwidth scenes. For the case of forming the coordinated multi-point apparatus (CoMP) set in a plurality of access points, the access point may be configured to transmit to the device of the pre-encoded using a common RB bundling size, in another aspect, the device is assigned to the case where the bandwidth and bandwidth extension, or may be separately determined for the bandwidth and the bandwidth extension jointly RB bundling size. RB bundling size can be determined based on bandwidth or bandwidth and bandwidth extension.
