Abstract

A method for configuring at least one component carrier (CC) for a physical downlink shared channel (PDSCH). The method includes receiving a CC configuration using a signaling protocol, wherein the CC is assigned using a semi-static configuration. Also included is a user equipment (UE) comprising a processor configured to receive a CC configuration for at least one CC for a PDSCH using a signaling protocol, wherein the CC is assigned using a semi-static configuration. Also included is an access node comprising a processor configured to transmit a CC configuration for at least one CC for a PDSCH using a signaling protocol, wherein the CC is assigned using a semi-static configuration.
