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: Methods and apparatus are disclosed for a UE and its serving base station in 5G NR systems to signal channel scan or channel sensing to allow channel occupancy time (COT) sharing before transmissions. The COT sharing may be initiated by the base station or by the UE by asserting a CCA indication to enable channel sensing by a UE or base station, respectively. When the UE receives and decodes the asserted CCA indication during downlink transmission, the UE may perform channel sensing during a short interframe space (SIFS) between the downlink transmission and a scheduled uplink transmission. When the UE detects that the sensed RF energy across an intended transmission band is greater than an energy detect threshold, the UE may refrain from transmitting during the scheduled uplink transmission. Otherwise or when the CCA indication is de-asserted, the UE may transmit during the scheduled uplink transmission without performing channel sensing.

Abstract: The present application relates to wireless devices and components including apparatus, systems, and methods for time-domain resource allocation for configured grant transmissions in New Radio (NR) systems operating on unlicensed spectrum. In some embodiments, a user equipment may be configured with periodicity, bitmap information, duration information, or slot-offset information to facilitate the time-domain resource allocation.

Abstract: The present application relates to wireless devices, and more particularly to apparatus, systems, and methods for multiplexing Configured Grant (CG) transmissions in New Radio (NR) systems operating on unlicensed spectrum. In one embodiment, a method for signaling a wireless system is disclosed, comprising: determining, by a user equipment (UE), that a physical uplink control channel (PUCCH) overlaps with a configured grant (CG) physical uplink shared channel (PUSCH) within a PUCCH group; multiplexing uplink control information (UCI) with a CG UCI based on the determination; and transmitting, by the UE to the wireless system, the multiplexed UCI with the CG UCI.

Abstract: A user equipment (UE), or other network component can operate to configure channel occupancy time (COT) sharing in random access procedures involving the unlicensed spectrum. At least some of the messages for the procedures can share a COT by configuring one or more gaps or listen-before-talk (LBT) procedures based on the gap or whether the COT sharing is UE or gNB initiated. Some configurations can depend on a location in the random access procedure that COT sharing is acquired.

Abstract: A user equipment (UE), or other network component can operate to generate listen-before-talk (LBT) operations in order to manage power consumption by configuring the discontinuous reception (DRX) in a dynamic manner. The UE can configure an extended active time for the DRX based on whether the LBT is successful and an acquisition channel indication from a base station, e.g., a next generation NodeB (gNB). The UE can operate aperiodic wakeup occasions with or independently of periodic DRX on-durations to better manage power while monitoring a channel for unlicensed carrier communications.

Abstract: Apparatuses of wireless communication devices are disclosed. An apparatus of a user equipment includes one or more processors configured to start a first timer responsive to detection of a Radio Link (RL) failure, start a second timer and trigger a beam recovery procedure one or more times responsive to expiry of the first timer if RL recovery is not detected, and start a third timer and attempt to find a suitable cell for Radio Resource Control (RRC) connection reestablishment responsive to one or more expiries of the second timer if RL recovery fails. The one or more processors are also configured to go to an RRC idle or inactive state responsive to expiry of the third timer if a suitable cell for RRC connection reestablishment is not found.

Abstract: Embodiments of the present disclosure describe apparatuses, methods and machine-readable storage medium for Reference Signal Received Power (RSRP) measurement and allocation of Downlink (DL) transmission resources. A user equipment (UE) may detect a first Synchronization Signal/Physical Broadcast Channel (SS/PBCH) block, and determine a subcarrier spacing (SCS) thereof. Mapping the first SS/PBCH block to OFDM symbols may be dependent on the SCS and a first SS/PBCH block index of the first SS/PBCH block. The UE may determine, based on the first SS/PBCH block and the SCS, a number of symbols of the slot or the slot pair for a CORESET for reception of a DL control channel associated with Remaining Minimum System Information (RMSI). The UE may decode the DL control channel in the CORESET. The DL control channel may be configured to indicate a DL data channel carrying the RMSI associated with the first SS/PBCH block.
