1. A method of transmission of transmission data from a first wireless station comprising first transmitter and a second transmitter to a second wireless station comprising a first receiver and a second receiver, comprising:
in the absence of detection of a failure of a radio link, de-multiplexing the transmission data between first data and second data at the first wireless station, transmitting the first data via only a first radio link from the first transmitter to the first receiver using a first subset of first radio resource blocks and transmitting the second data via only a second radio link from the second transmitter to the second receiver using a second subset of the first radio resource blocks, and aggregating the first data and the second data at the second wireless station to produce the transmission data, wherein the first subset of radio resource blocks does not include radio resource blocks from the second subset of radio resource blocks, and the second subset of radio resource blocks does not include radio resource blocks from the first subset of radio resource blocks;
monitoring the first radio link and the second radio link for a fault condition comprising a failure of the first radio link or the second radio link; and
dependent on the failure of the first radio link being detected, operating the second radio link from the second transmitter to the second receiver using a combination of the first and second subsets of the first radio resource blocks to transmit the transmission data, maintaining data capacity in the fault condition,
dependent on the failure of the second radio link being detected, operating the first radio link from the first transmitter to the first receiver using a combination of the first and second subsets of the first radio resource blocks to transmit the transmission data, maintaining data capacity in the fault condition.
