A method for establishing multiple radio connections by a user equipment (UE) is described. The method includes receiving a first physical downlink control channel (PDCCH) that includes a first cyclic redundancy check (CRC) scrambled by a first cell radio network temporary identifier (C-RNTI) in a primary radio connection. The method also includes decoding the first PDCCH. The method also includes receiving a second PDCCH that includes a second CRC scrambled by a second C-RNTI in a secondary radio connection. The method also includes decoding the second PDCCH.
