    Abstract: Embodiments include a computer readable storage medium, a user equipment, a method and an integrated circuit that perform operations. The operations include receiving a plurality of control resource sets (CORESETs), selecting a CORESET, wherein the CORESET includes one or more active transmission configuration indicator (TCI) states and determining a default beam or a pathloss reference signal (RS) based on a TCI state. Further operations include receiving a beam indication for a physical downlink control channel (PDCCH), wherein the PDCCH is received via one or more CORESETS, each having a plurality of TCIs, determining if the PDCCH collides with a second signal and determining whether to (a) drop the PDCCH or the second signal or (b) base a quasi co-location (QCL) of one of the PDCCH or the second signal on a QCL of the other one of the second signal or the PDCCH.

    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: 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: Embodiments include a computer readable storage medium, a user equipment, a method and an integrated circuit that perform operations. The operations include receiving a downlink channel information (DCI) format 2_0 from a g-NodeB (gNB) connected to the 5G NR network, wherein the DCI format 2_0 includes channel occupancy time (COT) duration and a gap threshold value, determining if a nonzero power channel state information reference signal (NZP-CSI-RS) resource is valid, wherein the NZP-CSI-RS resource is valid if the NZP-CSI-RS resource is within the COT duration and if a gap between a last symbol of the DCI format 2_0 and a first symbol of the NZP-CSI-RS resource is greater than the gap threshold value.

    Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing mechanisms for managing dormant cell(s) within a set of cells for multi-cell scheduling. For example, a UE can be configured to receive information associated with a set of cells for multi-cell scheduling and determine a first reference cell based on the received information. The UE is further configured to determine a second reference cell for performing one or more of blind decode counting and control channel element counting in response to determining that the first reference cell is in a dormant mode. The UE is further configured to perform the one or more of blind decode counting and control channel element counting using the second reference cell.
