Abstract: A base station indicates a resource allocation for a shared channel transmission to a user equipment, wherein the shared channel 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 the resource allocation, wherein N is at least two. The base station may also transmit, to the UE, a demodulation reference signal (DMRS) triggering (DMRS-T) value indicating a DMRS pattern to be used for a physical downlink shared channel (PDSCH) transmission by a base station, 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 transmits 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: The techniques described herein may include solutions for using downlink control information (DCI) to indicate dormancy for secondary cells (SCells). For DCI without a specific field for indicating dormancy for SCells, one or more fields of the DCI may be repurposed to report SCell dormancy. Repurposed fields may be arranged according to radio resource control (RRC) configuration information, a most significant bit (MSB), a least significant bit (LSB), and/or one or more bits being directed to specific SCell dormancy with one or more other bits being directed to SCell group dormancy, subsets of SCells, and/or a pre-defined rule. These and many other features and examples are described herein.

Abstract: Systems, apparatus, methods, and computer programs for coordination of communications between user equipment (UE). In aspect, a method can include receiving, by UE-B, data transmitted by UE-A, the received data comprising stage 2 sidelink control information (SCI) and an inter-UE coordination (IUC) message, determining, by the UE-B, a number of N combinations of TRIV, FRIV, and periodicity in the stage 2 SCI based on at least a portion of the received data, determining, by the UE-B, a payload size of the stage 2 SCI based on the determined number of N combinations, and decoding, by the UE-B, inter-UE coordination (IUC) message comprising stage 2 SCI based on the determined payload size.

Abstract: Systems and method are provided for determining access link direction beams for smart repeaters (SMRs). An SMR may be configured with a set of SMR transmission beam indicator (TBI) state (SMR-TBI State) configurations. The SMR-TBI State configurations in the set respectively comprise an SMR-TBI State identifier (ID), a cell index, and a reference signal associated with a beam for an access link between the SMR and a user equipment (UE). The SMR may receive, through a backhaul link from a base station, an indication of one or more active SMR-TBI States. For at least one of the one or more active SMR-TBI States, the SMR may forward a signal between the base station and the UE using the beam associated with the reference signal in a corresponding SMR-TBI State configuration.
