Abstract: Aspects of the present disclosure provide a mechanism for rate-matching between overlapping resource block (RB) sets within a transmission time interval (TTI). A physical downlink control channel (PDCCH) carrying downlink control information (DCI) including a downlink assignment for scheduling a physical downlink shared channel (PDSCH) may be received by a user equipment (UE) within the TTI.
