Methods, systems, and devices for interleaved mapping are described. In some implementations, a transmitting device identifies a set of virtual resource blocks (VRBs) corresponding to at least one code block to be transmitted to a receiving device. The transmitting device may determine that a quantity of VRBs to be transmitted to the receiving device is different than a quantity of entries within a regular interleaving matrix. Thus, the transmitting device may map each of the VRBs to a physical resource block (PRB) according to an irregular interleaving matrix to generate at least one interleaved code block. The transmitting device may transmit the interleaved code block to the receiving device. The receiving device may receive the interleaved code block and identify the PRBs associated with the interleaved code block. The receiving device may map each PRB within the interleaved code block to a VRB according to an irregular deinterleaving matrix.

Methods for interleaved mapping

A base station maps code blocks of a transport block of a transport block size (TBS) for a channel using tone-level interleaving or resource element (RE)-level interleaving. Then, the base station can transmit the code blocks of the transport block of the TBS for the channel. A UE may receive the channel from the base station and de-interleave the received tones of the channel in a frequency domain to obtain the code blocks of the transport block having the TBS for the channel.
