Title:
DEMODULATION REFERENCE SIGNAL (DMRS) BUNDLING IN SLOT AGGREGATION AND SLOT FORMAT CONSIDERATIONS FOR NEW RADIO
Document Type and Number:
WIPO Patent Application WO/2019/140342
Kind Code:
A1
Abstract:
Certain aspects of the present disclosure relate to communication systems, and more particularly, to techniques for time domain bundling of demodulation reference signals (DMRSs) in slot aggregation. An exemplary method generally includes detecting one or more conditions in at least one of a plurality of aggregated slots that indicate the at least one of the aggregated slots is not configured as a downlink-only slot, wherein each slot comprises a plurality of symbols, in response to the detection, determining whether to bundle demodulation reference signals (DMRSs) received across one or more of the aggregated slots, and performing channel estimation based on the determination.
