Abstract: A user equipment (UE) may include one or more processors that are configured to cause UE capability information to be communicated to a radio access network (RAN) node, regarding a maximum number of blind decode attempts (BDAs) supported by the UE. The one or more processors are configured to determine, based on the maximum BDAs, 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) and obtain sDCI by monitoring the sPDCCH in accordance with the determined sCCEs.

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: Embodiments of a User Equipment (UE), Generation Node-B (gNB) and methods of communication are disclosed herein. The UE may attempt to decode sidelink synchronization signals (SLSSs) received on component carriers (CCs) of a carrier aggregation. In one configuration, synchronization resources for SLSS transmissions may be aligned across the CCs at subframe boundaries in time, restricted to a portion of the CCs, and restricted to a same sub-frame. The UE may, for multiple CCs, determine a priority level for the CC based on indicators in the SLSSs received on the CC. The UE may select, from the CCs on which one or more SLSSs are decoded, the CC for which the determined priority level is highest. The UE may determine a reference timing for sidelink communication based on the one or more SLSSs received on the selected CC.

Abstract: A scrambling sequence generation method is disclosed for reference signals, data, and downlink and uplink control channels. The scrambling sequence generation method determines an initial seed value used to calculate the scrambling sequence. The initial seed value is based on different parameters relating to the to be transmitted signals, and some of these parameters are explicitly defined for New Radio.
