INDICATION OF POWER BOOSTING FOR PHYSICAL DOWNLINK CONTROL CHANNEL AND ITS IMPACT ON SEARCH SPACE

Abstract:

Aspects presented herein may improve the efficiency of power boosting of PDCCH by a base station and the blind PDCCH detection/decoding performed by a UE. In one aspect, the UE receives, from a base station, a power boost indication for a PDCCH. The UE determines at least one search space based on the power boost indication from the base station. The UE monitors for the PDCCH with the indicated power boost from the base station in the at least one search space. In another aspect, a base station transmits, to a UE, a power boost indication for a PDCCH. The base station applies a power boost to the PDCCH. The base station transmits the PDCCH with the power boost to the UE.
