    Abstract: Systems, devices, and techniques for wideband operations in unlicensed spectrum are described. A described technique receiving, by a user equipment (UE), a schedule for transmitting on a Physical uplink shared channel (PUSCH) over at least a portion of a plurality of listen-before-talk (LBT) subbands of a bandwidth part (BWP) in an unlicensed spectrum. The scheduled PUSCH bandwidth indicated by the schedule can be greater than a unit bandwidth of a LBT subband. The technique includes performing, by the UE, a LBT procedure on each scheduled LBT subband of the plurality of LBT subbands, each of the scheduled LBT subbands being associated with the scheduled PUSCH bandwidth. The technique includes performing, by the UE, a PUSCH transmission in accordance with the schedule that uses one or more of the scheduled LBT subbands that have passed the LBT procedure.

    Abstract: Systems and methods for determining channel raster(s) and synchronization signal raster(s) for New Radio (NR) unlicensed spectrum are disclosed herein. For each of a plurality of data objects an NR channel raster position is determined using Absolute Radio Frequency Channel Number (NR-ARFCN) numbers. For each corresponding NR channel, Global Synchronization Channel Numbers (GSCNs), a number of Physical Resource Blocks (PRBs) based on channel subcarrier spacing (SCS), NR channel raster position placement, channel edges, synchronization signal and physical broadcast channel (SSB) edges, and an SSB raster position are calculated. The plurality of data objects may then be down selected based on e.g., corresponding Long Term Evolution (LTE) channel raster positions and/or entries of a second plurality of data objects calculated for NR channels that use a second SCS.

    Abstract: Technology for a user equipment (UE), operable for monitoring a physical downlink control channel (PDCCH) is disclosed. The UE can monitor a downlink (DL) control channel for DL control information (DCI) at a predetermined monitoring occasion, wherein the predetermined monitoring occasion has a periodicity of P slots or P symbols with an offset Os. The UE can monitor a downlink (DL) control channel for DL control information (DCI) at a predetermined monitoring occasion, wherein Os has San offset with respect to a first slot in subframe number zero (SFN #0). The UE can monitor a downlink (DL) control channel for DL control information (DCI) at a predetermined monitoring occasion, wherein P is a positive integer greater than zero.

    Abstract: Techniques discussed herein can facilitate transmission and reception of group common PDCCH (Physical Downlink Control Channel) for NR (New Radio). One example embodiment employable by a UE (User Equipment) comprises processing circuitry configured to: process higher layer signaling that configures a set of combinations for slot formats for the UE; detect, via blind decoding on at least a portion of a control resource set, a DCI (Downlink Control Information) message that indicates a combination for slot formats of the set of combinations for slot formats via a SFI (slot format indicator); and determine a slot format for one or more slots based on the indicated combination for slot formats, wherein the slot format indicates, for each symbol of the one or more slots, whether that symbol is DL (Downlink), UL (Uplink), or a flexible symbol in the slot format.

    Abstract: Systems and methods are provided for increasing paging opportunities when the unlicensed band is used. A user equipment (UE) may determine a plurality of different paging occasions (POs) to monitor per DRX cycle. The plurality of different POs corresponds to beam sweep repeats for a first set of UEs in an unlicensed band from a base station in a wireless network. The UE monitors the plurality of different POs to receive the paging message from the base station. The plurality of different POs may include respective physical downlink control channel (PDCCH) monitoring occasions. The plurality of different POs may include at least two consecutive POs associate with the first set of UEs within a same paging frame. Alternatively, the plurality of different POs may include at least two non-consecutive POs associated with the first set of UEs separated by at least cycle one other PO associated with a second set of UEs.
