Certain aspects of the present disclosure relate to techniques for control channel resource mapping with transmit diversity. In an aspect, a method for wireless communications is provided with includes transmitting a signal associated with a downlink control channel, where the downlink control channel spans at least one group of resource elements (REs), and the group of REs indicates a first orthogonal resource to be used by a user equipment (UE). The method also includes signaling a second orthogonal resource to be used by the UE.
