Abstract
Aspects of the present disclosure provide techniques and apparatus for enhanced control channel element (ECCE) based physical downlink shared channel (PDSCH) resource allocation for long-term evolution (LTE). A method is provided for wireless communications by a user equipment (UE). The method generally includes determining resources assigned for a data channel, based on a resource granularity associated with a control channel and processing the data channel transmissions in a subframe based on the determination. The data channel may comprise a PDSCH. According to certain aspects, the UE may receive downlink control information (DCI) having a number of bits indicating VRBs assigned for PDSCH. Each VRB may include ECCEs from the same or different enhanced resource element group (EREG). ECCEs may span multiple PRB pairs or the same PRB pair. The UE may perform rate matching around enhanced physical downlink control channel (EPDCCH) overlapping assigned PDSCH resources.
