Abstract

Poor transmission reliability is identified in a data channel. Multiple frequency carriers are used to transmit different sets of data within the data channel. A frequency bin is assigned to each frequency carrier. The frequency bins are used to provide data to each frequency carrier. A transmission power assigned to each frequency carrier may be insufficient to overcome noise in the data channel when all the frequency bins are used to transfer data concurrently. The number of frequency bins associated with frequency carriers of the data channel are reduced. Power is increased to the available frequency bins to improve transmission reliability. The available frequency bins are allocated across the data channel according to a pattern used to spread allocated transmission power across the data channel. The frequency bin pattern is rotated among available frequency bins of the data channel, allowing different frequency bins to be used for each transmission. Accordingly, a power spectral density associated with the transmissions remains within a nominal power spectral density.
