1. A method of wireless communication, the method comprising:

  • allocating a first physical resource region for transmitting downlink grant information in a data region of a subframe, wherein the first physical resource region spans a first number of resource blocks in the subframe;

    encoding a first control channel for the downlink grant information; and

    interleaving the first control channel within the first physical resource region by a first interleaver corresponding to the first number of resource blocks, wherein the first number of resource blocks of the first physical resource region is determined by a user equipment (UE) through blind decoding with respect to multiple interleaver-candidates, each of the multiple interleaver-candidates corresponding to a different number of the resource blocks;

    allocating a second physical resource region for transmitting uplink grant information in the data region of the subframe, wherein the second physical resource region is disjoint from the first physical resource region;

    encoding a second control channel for the uplink grant information; and

    interleaving the second control channel within the second physical resource region by a second interleaver;

    wherein the second interleaver is a shifted version of the first interleaver.
