1. A wireless device comprising:
- a receive unit; and
a processor; and
the receive unit and the processor are configured to receive control data via control channels over at least a first communication channel or a second communication channel, the control data including a first assignment of downlink resources for the first communication channel and a second assignment of downlink resources for the second communication channel;
wherein the first communication channel and the second communication channel have different carrier frequencies;
wherein the first assignment of downlink resources indicates assigned orthogonal frequency division multiple access (OFDM) subcarriers of the first communication channel and the second assignment of downlink resources indicates assigned OFDM subcarriers of the second communication channel; and
the receive unit and the processor are further configured to receive downlink data on the assigned OFDM subcarriers of the first communication channel and the assigned OFDM subcarriers of the second communication channel;
wherein at least a portion of the downlink data is received at least in part simultaneously on the first communication channel and the second communication channel; and
the processor is configured to combine at least a portion of the received downlink data from the first communication channel and the second communication channel to produce data for a single service.

Abstract
Multiple channels are aggregated. In an example embodiment, first data is transmitted on a first channel to a wireless device, and second data is simultaneously transmitted on a second channel to the wireless device. The first data and the second data are transmitted in a coordinated manner by aggregating the first channel and the second channel. Various example channel characteristics and combinations thereof are described. Different data allocation options for aggregated channels are described. Other alternative implementations are also presented herein.
