Abstract: Systems, apparatuses, methods, and computer-readable media are provided for a user equipment (UE) device that includes one or more processors configured to identify a search space for physical downlink control channel (PDCCH) candidates by: determining whether the search space is a group common search space or a UE specific search space; determining a number of PDCCH candidates per aggregation level (AL); determining a PDCCH monitoring periodicity and a PDCCH monitoring offset for the search space, each including a plurality of slots; determining monitored slots in the monitoring periodicity; determining, for each monitored slot, a monitoring pattern including a set of selected symbols; and determining a set of monitoring occasions corresponding to the set of selected symbols in each monitored slot of each monitoring periodicity. The one or more processors are configured to decode downlink signals received in the set of monitoring occasions to search for PDCCH information for the UE.

Abstract: User equipment (UE) includes processing circuitry coupled to memory. To configure the UE for multi-transmission reception point (TRP) reception, the processing circuitry is to decode radio resource control (RRC) signaling. The RRC signaling includes configuration information configuring a plurality of transmission configuration indication (TCI) states. A media access control (MAC) control element (CE) is decoded, where the MAC CE indicates multiple active TCI states of the configured plurality of TCI states. Multiple received beams are determined using the multiple active TCI states. Downlink information is decoded, where the downlink information originates from multiple TRPs and is received via the determined multiple receive beams associated with the multiple active TCI states.

Abstract: A device of a New Radio (NR) User Equipment (UE), a system, a method and a machine-readable medium. The device includes a radio frequency (RF) interface, and a processing circuitry coupled to the RF interface, the processing circuitry to: decode a message from a NR Node B (gNodeB), the message corresponding to a unicast message or to a broadcast message and being received through a Universal Mobile Telecommunications System (UMTS) interface (Uu interface), the message further including reference time information; and determine a reference time from the reference time information, the reference time to be used by higher layers of the UE.
