Abstract: Embodiments may be directed to techniques to determine physical downlink control channel (PDCCH) candidates to assign to a user equipment (UE) based on one or more aggregation levels, each PDCCH candidate in a highest aggregation level of the one or more aggregation levels assigned by a random distribution over a whole control channel element (CCE) domain, and each PDCCH candidate in one or more non-highest aggregation levels of the one or more aggregation levels assigned a random distribution over one or more CCEs utilized by PDCCH candidates of the highest aggregation level. Embodiments also include selecting at least one of the PDCCH candidates to utilize to send downlink control information (DCI) to the UE, and causing transmission of the DCI to the UE via the PDCCH candidates selected.
