In accordance with aspects of the disclosure, a method, apparatus, and computer program product are provided for wireless communication. The method, apparatus, and computer program product, in an implementation, may be configured to provide separate control channels for each of downlink grant information and uplink grant information, encode the control channels with an identifier known only to receiving nodes that are configured to decode the control channels with the identifier, and convey information to the receiving nodes that the identifier is known to the receiving nodes. The method, apparatus, and computer program product, in an implementation, may be configured to determine an aggregation level of a common search space related to common control resources, wherein the aggregation level is less than four, and receive control data from one or more candidates in the common search space that include contiguous control channel elements according to the aggregation level. |

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. |
