Title
(EN) MEASUREMENT OF POWER LEVEL OF DEMODULATION REFERENCE SIGNAL PRIOR TO BLIND DECODING OF ASSOCIATED PHYSICAL DOWNLINK CONTROL CHANNEL
Abstract
(EN)

A scheduled entity measures a power level of a demodulation reference signal (DMRS) prior to blind decoding a physical downlink control channel (PDCCH) candidate associated with the DMRS. The scheduled entity performs blind decoding of the PDCCH candidate if the power level is above a predetermined threshold or foregoes blind decoding if the power level is below the predetermined threshold. A scheduling entity transmits a blind decoding configuration setting to the scheduled entity. The scheduling entity enables, via the blind decoding configuration setting, measurement, at the scheduled entity, of power levels of a plurality of DMRSs prior to blind decoding a plurality of respective PDCCH candidates associated with the plurality of DMRSs. Only PDCCH candidates associated with DMRSs having power levels that are above the predetermined threshold are blind decoded. A predetermined number of PDCCH candidates are scheduled for blind decoding. Blind decoding stops when the predetermined number is reached.
