Link Adaptation Within Transport Blocks

For a network node in wireless communication with a UE, filling a TB such that at least two data with different reliability requirements are mapped to separate CBs. The network node applies different MCSs to at least the separate CBs comprising the data with different reliability requirements within the transport block. The network node transmits the TB toward the UE after the different MCSs have been applied. The UE can use a similar technique in UL in order to transmit. The UE may also receive the TB from the network node. The UE decodes and performs error checking of the CBs based on the corresponding MCSs that were applied.
