Abstract: Methods, systems, and devices for wireless communications are described. A base station may configure a user equipment (UE) with a multiple listen-before-talk (LBT) bandwidths, where each LBT bandwidth is associated with one or more downlink control channel candidates of a search space for a control resource set. The UE may monitor the LBT bandwidths during a wakeup signal period for a wakeup signal from the base station. The UE may be configured with a total number of blind hypotheses in the set of blind hypotheses which is equal to or greater than a total number of LBT bandwidths. The UE may determine whether to wake up and monitor an on duration of a discontinuous reception cycle based on detection of the wakeup signal.

Abstract: Wireless communications systems and methods related to autonomous sidelink communication in a radio frequency band (e.g., in a shared spectrum or an unlicensed spectrum) shared by multiple network operating entities are provided. A first user equipment (UE) performs a listen-before-talk (LBT) in a shared radio frequency band based on a first starting point of a plurality of starting points within an LBT gap duration. The first UE transmits, to a second UE, a first sidelink communication in the shared radio frequency band based on the LBT, the first sidelink communication including first sidelink control information (SCI) and first sidelink data.

Abstract: Aspects of the present disclosure provide techniques for design of synchronization signals for narrowband operation and other clean-slate, OFDM based systems such as enhanced component carrier (eCC) systems. An example method is provided for operations which may be performed by a BS to generate and transmit a dual-layer PSS, and correspondingly, techniques for a UE to detect the dual-layer PSS. The PSS may be generated utilizing a binary code cover and at least one sequence applied to a number of symbols within one or more subframes of a frame.

Abstract: Aspects presented herein provide for dual connectivity with a standalone service provider in the unlicensed spectrum. A first base station may receive, from a UE, an indication of a capability for standalone operation in a first RAT that utilizes an unlicensed frequency spectrum and a dual connectivity capability involving the first RAT and a second RAT that utilizes a licensed frequency spectrum, wherein dual connectivity comprises the UE being connected to a master base station on a first frequency and a secondary base station on a second frequency at a same time. The first base station may signal a first set of procedures for dual connectivity when the level of support at the first base station is at higher layers of the first RAT and may signal a second set of procedures when the level of support at the first base station extends to lower layers of the first RAT.

Abstract: Methods, systems, and devices are described for hierarchical communications and low latency support within a wireless communications system. An eNB and/or a UE may be configured to operate within the wireless communications system which is at least partially defined through a first layer with first layer transmissions having a first subframe type and a second layer with second layer transmissions having a second subframe type. The first subframe type may have a first round trip time (RTT) between transmission and acknowledgment of receipt of the transmission, and the second layer may have a second RTT that is less than the first RTT. Subframes of the first subframe type may be multiplexed with subframes of the second subframe type, such as through time division multiplexing. In some examples symbols of different duration may be multiplexed such that they different symbol durations coexist.

Abstract: New radio (NR) unlicensed (NR-U) operations are discussed with channel occupancy time (COT) multiple downlink-uplink switching opportunities supported by an active channel indication. A network node that initiates a COT for transmissions may identify a within-channel occupancy time (COT) scheduled downlink-uplink switching configuration. After beginning transmissions on the COT, the node receives an active channel indication from one or more additional network nodes. In response to the active channel indication, the node may then perform communications with the node from which the active channel indication is received according to the within-COT scheduled downlink-uplink switching configuration for the current COT on a shared communication channel.
