## Abstract

Provided are methods and corresponding apparatuses for allocation of resource blocks. A method for allocation of resource blocks comprises receiving, from a base station, information regarding a measurement location at which at least one identified resource block has been measured; and using, based upon a current location of a mobile relay node and the measurement location, the at least one identified resource block for communication between the mobile relay node and at least one user equipment connected therewith, wherein the at least one identified resource block is not used for communication between the base station and at least one user equipment connected therewith at the measurement location and a measurement of the at least one identified resource block is below a predetermined threshold. With the claimed inventions, interference in the high speed railway communication could be ameliorated and the spectrum efficiency would be improved.
