A method for operating a UE includes receiving, by the UE during an initial access sequence, a plurality of first inbound beams each transmitted by a communications controller in a different transmit direction over a first carrier, where the first inbound beams have a different subcarrier frequency range from each other, generating values of a receive metric in accordance with the first inbound beams, selecting one of the first inbound beams in accordance with the receive metric values, transmitting, by the UE, an indication of the selected first inbound beam, and receiving, by the UE, a second inbound beam transmitted by the communications controller in a transmit direction in accordance with the indication of the selected first inbound beam, where the second inbound beam has a second subcarrier frequency range of the first carrier that is different than a first subcarrier frequency range of the selected first inbound beam. |
