Virtual resource block to physical resource block mapping in new radio

A method for wireless communications performed by a user equipment (UE), comprising:

• determining an interleaved mapping that maps an interleaving unit of N consecutive virtual resource blocks (VRBs) to N consecutive physical resource blocks (PRBs), wherein N is greater than one, wherein each PRB comprises a plurality of resource elements, wherein the interleaved mapping maps each interleaving unit of a plurality of interleaving units to a corresponding PRB bundle of a plurality of PRB bundles, wherein each PRB bundle of the plurality of PRB bundles has N PRBs, and wherein indices of the N consecutive VRBs are different from indices of the N consecutive PRBs;
• receiving a grant allocating the interleaving unit of N consecutive VRBs from a base station (BS), wherein the grant allocates the plurality of the interleaving units;
• and
• communicating with the BS via the N consecutive PRBs mapped to the N consecutive VRBs of the interleaving unit.

An apparatus for wireless communications, comprising:

• a processor configured to:
• determine an interleaved mapping that maps an interleaving unit of N consecutive virtual resource blocks (VRBs) to N consecutive physical resource blocks (PRBs), wherein N is greater than one, wherein each PRB comprises a plurality of resource elements, wherein the interleaved mapping maps each interleaving unit of a plurality of interleaving units to a corresponding PRB bundle of a plurality of PRB bundles, wherein each PRB bundle of the plurality of PRB bundles has N PRBs, and wherein indices of the N consecutive VRBs are different from indices of the N consecutive PRBs;
• transmit a grant allocating the interleaving unit of N consecutive VRBs to a user equipment (UE), wherein the grant allocates the plurality of the interleaving units;
• and
• communicate with the UE via the N consecutive PRBs mapped to the N consecutive VRBs of the interleaving unit;
• and
• a memory coupled with the processor.
