US 2020/0008235 A1 · PDCCH WITH REPETITION

Abstract

Certain aspects of the present disclosure provide techniques for physical downlink control channel (PDCCH) with repetitions, including techniques for signaling the number of PDCCH repetitions, the hybrid automatic repeat request (HARD) timeline processing with PDCCH repetitions, and the demodulation reference signal (DMRS) structure for the repeated PDCCH. A method for wireless communications, by a user equipment (UE), includes determining a number of repetitions of a PDCCH. Each of the PDCCH repetitions has a same downlink control information (DCI) payload, a same aggregation level, and/or a grant for a same data channel allocation. The method includes monitoring for the PDCCH based on the determined number of repetitions.
