Abstract: A user equipment (UE) receives a resource allocation for a shared channel transmission that includes mapping modulated symbols of a transport block with a single dedicated hybrid automatic repeat request (HARQ) process number across resource elements for N consecutive slots of the resource allocation, wherein N is at least two. The UE may also receive, from a base station, a demodulation reference signal (DMRS) triggering (DMRS-T) value indicating a DMRS pattern to be used for a physical downlink shared channel (PDSCH) transmission, wherein the PDSCH transmission includes mapping modulated symbols of a transport block with a single dedicated hybrid automatic repeat request (HARQ) process number across resource elements for N consecutive slots of a PDSCH resource allocation, wherein N is at least two and measure transmitted DMRS based on the DMRS pattern corresponding to the DMRS-T value.

Abstract: A cell performs beam management operations for a user equipment (UE). The cell transmits a first group of multiple reference signals via a first transmission reception point (TRP) to a user equipment (UE), transmits a second group of multiple reference signals via a second different TRP to the UE, receives an indication that the UE has selected a first beam associated with one of the multiple reference signals of the first group and a second beam associated with one of the multiple reference signals of the second group and transmits downlink data to the UE using the first beam and the second beam.

Abstract: Beam failure recovery (BFR) in a multiple Downlink Control Information (mDCI) mode may include receiving, by a user equipment (UE), a Downlink Reference Signal (DL RS) set from a next generation Node B (gNB). The DL RS set may be associated with a link between the UE and the gNB and indicate beam failure detection (BFD) is to be performed for the link. The BFR may further include performing, by the UE, a beam failure detection (BFD) for the link using the DL RS set, and performing, by the UE, a candidate beam detection (CBD) for the link, the CBD determining a candidate beam for the link by determining a beam having a reference signal receiving power (RSRP) that is larger than an RSRP threshold. The BFR may further include transmitting, by the UE, a beam failure recovery request (BFRQ) indicating the link to the gNB.

Abstract: A base station communicates with a first user equipment (UE) and a second UE. The base station determines a first configuration for the first UE for a channel state information reference signal (CSI-RS) on a symbol, schedules a data transmission for the second UE on the symbol where the CSI-RS is configured so that the CSI-RS and the data transmission collide on the symbol and determines a second configuration for the first UE when the CSI-RS and the data transmission collide on the symbol.
