Abstract: Apparatuses, methods, and systems are disclosed for directional LBT procedure for DRS transmission. One apparatus (800) includes a processor (805) and a transceiver (825) that is operable on unlicensed spectrum. The processor (805) indicates (905) block locations within a Discovery Reference Signal ("DRS") transmission window for a plurality of candidate 5 Synchronization Signal/Physical Broadcast Channel ("SS/PBCH") blocks. The processor (805) performs (910) a Listen-Before-Talk ("LBT") procedure for a plurality of DRS transmissions within a DRS transmission window and controls the transceiver (825) to transmit (915) – for a given spatial direction – a SS/PBCH block upon successful LBT for the given spatial direction.

Abstract: 本公开涉及通信技术领域，尤其涉及一种信道监听的指示方法、装置及存储介质。所述方法包括：用户设备接收下行控制信息，所述下行控制信息用于指示是否停止监听物理下行控制信道和/或停止监听所述物理下行控制信道的时长。本公开实施例通过将指示物理下行控制信道监听行为切换的信息与当前的下行控制信息进行合并，完成物理下行控制信道监听状态的切换指示，进而使得用户设备根据下行控制信息的指示对物理下行控制信道进行监听或者停止监听，无需监听每个物理下行控制信道，降低了用户设备的功耗，优化了对物理下行控制信道的监听行为。

Abstract: Certain aspects of the present disclosure provide techniques for low power channel sensing for pedestrian user equipments (P-UEs). A method that may be performed by a UE (e.g., such as a P-UE) includes determining a level of channel congestion for a channel during a first sensing duration. The method includes determining a second sensing duration and a transmission duration based on the level of channel congestion for the channel determined from the first sensing duration. The method includes sensing the channel for the second sensing duration. The method includes transmitting on the channel for the transmission duration.

Abstract: Configurations for configured grant (CG) in new radio unlicensed (NR-U) systems is disclosed. CG configurations may, based on a periodicity, be provided either using a bitmap, shorter periodicity, or resource indicator value (RIV) signaling of start/end symbols, longer periodicity. Such CG configurations configure M sets of time division resource allocations. CG configuration may include common start/end symbols from for all contiguous allocations in one configuration. Common LBT starting points may be defined for all configured slots as indicated through a bitmap. The CG configuration allows for mini- and full slot configurations, in which the mini-slots are configured within the already configured CG slots. Repetition configurations include a type 1 for coverage and a type 2 for faster retransmission and reduced downlink feedback information (DPI) overhead. With multiple UEs, a UE identifier is added to the uplink control information (UCI). UEs may further ramp up power in the absence of DPI.
