Aperiodic CSI over multi-TRP pusch

Abstract

Systems and methods for aperiodic Channel State Information (CSI) over multi-Transmission / Reception Point (TRP) Physical Uplink Shared Channel (PUSCH) are provided. In some embodiments, a method performed by a wireless device for providing feedback includes: repeating PUSCH over multiple M>1 PUSCH occasions with P spatial relations and / or Uplink Transmission Configuration Indicator (TCI) states; and multiplexing Aperiodic CSI (A-CSI) with PUSCH on N>=1 PUSCH transmission occasions wherein N includes at least one PUSCH transmission occasion associated with each of the P spatial relations or UL TCI states. This may enable improved A-CSI reliability in multiTRP scenarios. By repeating A-CSI (multiplexed with PUSCH or not multiplexed with PUSCH) over multiple TRPs, the reliability of A-CSI can be improved since the ACSI can be received by at least one TRP. This method is particularly beneficial in FR2 cases where the channel between a TRP and a UE can experience channel blocking.
