Title:
ＰＤＳＣＨダイバーシティをシグナリングするためのシステム及び方法
Document Type and Number:
Japanese Patent JP7228693
Kind Code:
B2
Abstract:
Systems and methods for signaling for Physical Downlink Shared Channel (PDSCH) diversity are provided. In some embodiments, a method performed by a wireless device for receiving a plurality of downlink transmissions includes determining an association between one or more Demodulation Reference Signal (DMRS) ports and one or more associated Redundancy Values (RVs). The method also includes receiving the plurality of downlink transmissions using the association. In some embodiments, this enables a single Downlink Control Information (DCI) to be used to schedule different redundancy versions of the same transport block from the different Transmission/Reception Points (TRPs) which helps improve reliability of decoding a transmission successfully within stringent latency requirements.
