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 user equipment (UE) is configured to receive a system information block (SIB) from a base station, wherein a dedicated set of physical random access channel (PRACH) resources for redcap devices are explicitly configured in the SIB and transmit, in response to the SIB, an indication to the base station that the UE is a reduced capability (redcap) device.

Abstract: Systems, methods, and apparatuses disclosed herein can operate on an unlicensed spectrum. These systems, methods, and apparatuses can perform a first listen-before-talk (LBT) operation of a LBT protocol in a first slot from among multiple slots to determine whether the unlicensed spectrum is unoccupied. Thereafter, these systems, methods, and apparatuses can transmit an uplink (UL) transmission in other slots from among the plurality of slots in response to the unlicensed spectrum being unoccupied. Otherwise, these systems, methods, and apparatuses can perform a second LBT operation in a second slot from among the plurality of slots in response to the unlicensed spectrum being occupied.

Abstract: Systems, devices, and techniques for user equipment (UE) power control are described. A described technique includes receiving, by a UE, a discontinuous receiving (DRX) configuration from a base station; monitoring, by the UE on a physical downlink control channel (PDCCH), for downlink control information (DCI) messages outside of a DRX active time, the DCI messages being of a predetermined format that is configured to provide wake-up signaling; receiving, by the UE, a DCI message outside of the DRX active time, the DCI message being of the predetermined format; and determining, by the UE, whether to wake-up based on the received DCI message.

Abstract: Systems, methods, and apparatuses are provided for determining a number of physical downlink control channel (PDCCH) candidates and non-overlapped control channel elements (CCEs) for a UE configured with a plurality of component carriers having more than one subcarrier spacing (SCS). The plurality of component carriers are assigned to a number of cell groups. Each cell group includes a scheduling component carrier providing scheduling information for the other component carriers in the cell group. A reference slot window is selected based on an SCS of component carriers assigned to each cell group. And a number of PDCCH candidates and non-overlapped CCEs per the reference slot window are determined based on a number of and SCS of the component carriers in each cell group. Control information in a downlink radio frame is monitored by the UE based on the number of PDCCH candidates and non-overlapped CCEs.

Abstract: The disclosure describes configuration schemes for secondary cell (SCell), bandwidth part (BWP) and physical resource block (PRB) indexing. An apparatus of user equipment (UE) for BWP activation and deactivation operation is disclosed, The apparatus includes baseband circuitry that includes a radio frequency (RF) interface, and one or more processors. The one or more processors are to receive radio resource control (RRC) data via the RF interface, configure a timer for a BWP according to the RRC data, and trigger the timer for the BWP in response to detection of an event associated with an access node after the BWP has been activated.

Abstract: A user equipment (UE) is configured to change a transmission configuration indicator (TCI) state. The receives, from the base station, a network flag indicating a transmission configuration indicator (TCI) state change configuration for the network, determines a time span for continuing to use a current TCI state prior to switching to a new TCI state based on the network flag and switches to the new TCI state after the time span.

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.
