Search space determination

摘要

Embodiments of the present disclosure describe apparatuses, systems, methods, and articles of manufacture for identifying search space candidates that may be used in the transmission of downlink control information. Other embodiments may be described and claimed.

主权项

1. An apparatus comprising:
an encoder configured to:
determine a set of search space candidates of an enhanced-physical downlink control channel (E-PDCCH) based on an aggregation level of downlink control information (DCI), predetermined spacing between adjacent search space candidates, and a number of virtual resource blocks (VRBs) of the E-PDCCH, the set of search space candidates to be potential bearers of DCI;select one or more VRBs from the set of search space candidates; andencode DCI onto the selected VRBs; and a mapper configured to map the VRBs of the E-PDCCH to physical resource blocks (PRBs) for transmission to a user equipment in a downlink frame, wherein the predetermined spacing is to provide an even distribution of the search space candidates across VRBs of the E-PDCCH to enable a frequency scheduling gain.
