US Patent 11683739 Radio link aggregation

A network device distributes a plurality of symbol blocks, received via a plurality of input streams, to a plurality of output links comprised in a defined connection according to a mapping of the symbol blocks to the output links. Responsive to an input stream of the plurality of input streams being empty such that an expected symbol block is not received, the network device distributes idle data to the output link mapped to the expected symbol block to maintain the mapping of the symbol blocks to the output links. The network device transmits the symbol blocks and idle data over the defined connection via the plurality of output links and according to the distribution.
