Abstract: A periodic quiet interval is provided for base stations attempting to access a shared transmission medium in NR-U. The base station activates a quiet interval at a periodic interval and transmits on the medium based on the quiet interval. The base station may reduce a Tx power, not transmit, and/or may increase a minimum value of a contention window for BEB during the quiet interval. The base station may receive a request from a second base station to activate the quiet interval, and may determine if a Tx power of the base station is larger than the maximum Tx power of the second base station. The base station may also receive the request as relayed through a UE. The quiet interval can thus ameliorate a starvation effect of BEB in NR-U by allowing base stations with smaller Tx power greater opportunity to control the medium while maintaining BEB in NR-U.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a device may select a plurality of channel access intervals during which the device is associated with a priority condition relative to another device for communications by the device, wherein each of the plurality of channel access intervals includes a respective contention interval and a respective transmission opportunity; and may transmit, during a contention interval of a first channel access interval of the plurality of channel access intervals, a signal that includes: channel occupancy information for the device for a first transmission opportunity of the first channel access interval, and information that identifies at least a portion of one or more subsequent channel access intervals, of the plurality of channel access intervals, associated with the device. Numerous other aspects are provided.

Abstract: Various aspects described herein relate to communicating in a wireless network. A resource grant comprising an indicator of whether to transmit a demodulation reference signal (RS) for an uplink control channel or an uplink data channel can be received from a network entity. It can be determined whether to transmit the RS in at least one transmission time interval (TTI) based at least in part on the indicator.

Abstract: Techniques for uplink transmission management in a wireless communications system are described herein. An example method may include receiving an explicit uplink grant that indicates one or more implicit uplink grants. In an aspect, the example method may include performing a first clear channel assessment (CCA) in response to the explicit uplink grant in a first time slot. In another aspect, the example method may include, if the first CCA fails, sequentially performing one or more additional CCAs respectively in one or more time slots subsequent to the first time slot in response to the one or more implicit uplink grants, and transmitting the PDU over the unlicensed or shared spectrum and in a time slot subsequent to the time slot in which one of the one or more additional CCAs succeeds.

Abstract: Wireless communications systems and methods related to reclaiming of resources in a shared frequency spectrum shared by multiple operators are provided. A first wireless communication device associated with a first operator of a plurality of operators identifies a transmission opportunity in a shared frequency spectrum shared by the plurality of operators, wherein the first operator has priority among the plurality of operators for accessing the shared frequency spectrum in the transmission opportunity. The first wireless communication device communicates with a second wireless communication device associated with the first operator, in the transmission opportunity without a prior reservation of the transmission opportunity.
