Abstract: A user equipment (UE) may receive information, via radio resource control (RRC) signaling, regarding a search space of a physical downlink control channel (PDCCH) for obtaining downlink control information (DCI) from a radio access network (RAN) node. Based on a slot format (SF) index in the DCI, the UE may determine a slot format for communicating with the RAN node, and communicate with the RAN node in accordance with the slot format. Additionally, a UE may communicate UE capability information, which may include a maximum number of blind decode attempts (BDAs), to the RAN node. The UE may determine shortened channel control elements (sCCEs) to be used, by the RAN node, to transmit shortened downlink control information (sDCI) via a shortened physical downlink control channel (sPDCCH), obtain sDCI by monitoring the sPDCCH in accordance with the determined sCCEs, and communicate with the RAN node in accordance with the sDCI.

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.
