Abstract: 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.

Abstract: Methods, systems, and devices for wireless communications are described Techniques described may be utilized to avoid errors caused by resource allocation calculations, which may be indicated via higher layer signaling and/or determined within DCI. A base station may transmit downlink control information indicating resource allocation types to avoid errors. In other cases, the UE and/or base station may designate a particular resource block group size to avoid the potential errors. The UE and/or base station may calculate a number of resource blocks groups for a bandwidth part and allocate the size of the resource block group based on the calculation. The UE and/or base station may conduct a comparison between a bandwidth part size and a resource block group size to determine whether to designate a different resource block group size to avoid the errors. Similar techniques may be utilized in allocating resources for precoding resource block groups.
