Abstract: Wireless communications systems and methods related to improving detectability of interference management signals are provided. A first wireless communication device communicates, with a second wireless communication device, a first reservation signal indicating a reservation for a first transmission slot in a spectrum accessed by a plurality of network operating entities. The first wireless communication device and the second wireless communication device are associated with a first network operating entity of a plurality of network operating entities. The first reservation signal includes a duration based on a power class associated with the first network operating entity. The first wireless communication device communicates, with the second wireless communication device, a first communication signal in the first transmission slot.

Abstract: Techniques for synchronization across transmitting nodes of a same public land mobile network (PLMN) operator using a shared radio frequency spectrum band may include initiating, at a first wireless node, a listen-before-talk (LBT) procedure for access to the shared radio frequency spectrum band, and identifying that a second wireless node associated with a same PLMN operator as the first wireless node has won contention for the shared radio frequency spectrum band. The first wireless node may discontinue the LBT procedure and initiate an auxiliary transmission using the shared radio frequency spectrum band concurrently with a primary transmission of the second wireless node.

Abstract: Autonomous uplink (AUL) for wideband new radio (NR) unlicensed (NR-U) operations is disclosed. For user equipments (UEs) that have been configured for AUL transmissions and have received an activation signal to activate the AUL capabilities, further indications may be used to enable AUL transmissions on AUL transmission opportunities (TxOPs) that overlap the timing of a current TxOP reserved by a serving base station, but that are allocated outside of the resources reserved for the current TxOP. A UE that identifies a desired, next AUL TxOP that overlaps the current base station-initiated TxOP duration, but is allocated for resources outside of the current TxOP resources determines whether it has obtained an enablement indication either directly from the serving base station or implicitly, based on current conditions at the UE. When the UE determines that it has obtained an enabling indication, it may then perform AUL transmissions via the overlapping AUL TxOP.

Abstract: Aspects of the present disclosure relate to wireless communications and, more particularly, to synchronization for standalone long term evolution (LTE) broadcast. In one aspect, a method is provided which may be performed by a wireless device such as a base station (BS). The method generally includes providing unicast coverage to one or more user equipments (UEs) in a unicast coverage area within a larger coverage area, transmitting unicast data in one or more subframes, and transmitting synchronization signals within one or more of the broadcast subframes, wherein the broadcast signals are transmitted as single frequency network (SFN) transmissions synchronized with transmissions from one or more other base stations providing unicast coverage within the larger coverage area.

Abstract: Techniques are described for preempting resource allocations to one or more UEs in the event that delay sensitive data is received. A resource allocation of a number of symbols may be granted to a first user equipment (UE) for first associated data to be transmitted. Subsequently, data may be received for a second UE that is more delay sensitive than the first data. The resource allocation to the first UE may be preempted, and resources allocated to the second UE for the second data within a variable length transmission time interval (TTI) of the resource allocation to the first UE. UEs may monitor for preemption during transmissions to other UEs in order to receive new resource grants associated with the preempted resource grant. Whether a UE monitors transmissions for preemption may be determined based on a quality or service (QoS) of the UE.

Abstract: Wireless communication systems and methods related to spectrum use negotiations are provided. A first wireless communication device transmits, to a controlling entity of a spectrum, a spectrum use request for a local operator to use the spectrum for a time period. The first wireless communication device receives, from the controlling entity, a spectrum use grant indicating that the local operator is promoted from a first priority to a second priority for accessing the spectrum during the time period. The first wireless communication device communicates with a second wireless communication device in the spectrum during the time period based on the second priority, where at least the first wireless communication device or the second wireless communication device is associated with the local operator.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitter device may determine that a communication is to be transmitted on a shared spectrum during a channel access interval not reserved for the communication. The transmitter device may determine, based at least in part on determining that the communication is to be transmitted, that a detection power of a listen-before-talk (LBT) operation satisfies a threshold. The transmitter device may transmit, after a coordinated rate control region and based at least in part on the detection power of the LBT operation satisfying the threshold, a reservation request signal associated with the communication. The transmitter device may transmit the communication before an end of the channel access interval based at least in part on a response to the reservation request signal. Numerous other aspects are provided.

Abstract: Techniques are described for wireless communication. A first method includes transmitting a first signal to indicate accessing a first channel in a radio frequency spectrum band, and transmitting information with the first signal in the radio frequency spectrum band. A second method includes winning contention to access a radio frequency spectrum band, and after the winning contention to access the radio frequency spectrum band, transmitting a first signal to align a starting point of a second signal with a reference boundary associated with the radio frequency spectrum band. A third method includes winning contention to access a radio frequency spectrum band during a first frame period, the first frame selected from a plurality of different frame periods, and transmitting a signal at a periodicity during one or more subframes of the first frame period for each of the plurality of different frame periods.
