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: Some embodiments of this disclosure include apparatuses and methods for multiplexing uplink (UL) and/or downlink (DL) data transmission packets in user equipment (UE). In some embodiments, the UE may receive a resource configuration from a network node including one or more parameters for establishing a communication channel. The UE may receive a command from the network node indicating a UL grant for packet transmission from the UE. While preparing to transmit a first packet corresponding to the UL grant, the UE may receive a second packet having a higher priority designation, wherein the second packet includes an overlapping symbol with the first packet. The UE may transmit the second packet in view of this higher priority.

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: Methods and systems are provided for communicating in a wireless network based on a prioritization status. User equipment can receive a first signal that includes an indicator. The UE can determine a prioritization status for a second signal based on the prioritization indicator. The UE can communicate, with one or more radio access networks (RANs) of a network, the second signal, where the timeline of the second signal can be out of order respective of other signals communicated by the UE and the wireless network. The second signal can include data transmitted by an ultra-reliable low latency communication (URLLC) service. The UE can communicate the second signal out of order with respect to one or more additional signals. The UE, based on the indicator, can communicate hybrid automated repeat request (HARQ) feedback before a HARQ feedback timeline of a non-urgent transmission.
