Abstract: Techniques are described for wireless communication at a wireless device. One method includes identifying a priority of the wireless device for a transmission interval of a radio frequency spectrum band shared by a plurality of network operating entities; identifying an absence of a predetermined transmission type in each of a number of clear channel assessment (CCA) slots of the transmission interval, in which each of the number of CCA slots is associated with a higher priority than the identified priority of the wireless device; and communicating over the radio frequency spectrum band based at least in part on the identified absence of the predetermined transmission type in each of the number of CCA slots associated with the higher priority than the priority of the wireless device.

Abstract: Aspects of the disclosure relate to wireless communication systems configured to share a shared spectrum with one or more other systems (e.g., other operator networks utilizing the same radio access technology, and/or other networks utilizing different radio access technologies). Coexistence between the different systems on the shared spectrum may be provided by utilizing a technology-neutral signature waveform such as a signature sequence or discovery signal. The signature sequence may be used for resource reservation, scheduling, and coordination among disparate systems operating on a shared spectrum. Other aspects, embodiments, and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless node may receive stress beacons on a channel. Each stress beacon may include an indication of an allowable interference level for a corresponding wireless node that transmitted the stress beacon on the channel. The wireless node may update a backoff window for the channel based on the allowable interference levels indicated in the stress beacons.

Abstract: Various aspects described herein relate to techniques of spectrum sharing in beacon-assisted multi-tier wireless communications systems (e.g., 5G New Radio). A method of spectrum sharing in multi-tier wireless communications is provided that may include generating, at a first apparatus, a beacon signal including information of spectrum usage, wherein the information includes at least one or more of a pilot reference, resources allocation, one or more usage entities, or one or more sharing parameters, and sending the beacon signal to at least a second apparatus, wherein the first apparatus and the second apparatus are in a same tier or different tiers.

Abstract: Techniques for synchronization on a shared communication medium are disclosed. An access point may select, for example, a common sequence, frequency, and time for a first synchronization signal that is coordinated with one or more other access points. The access point may then transmit the first synchronization signal in accordance with the common sequence, frequency, and time. An access terminal may receive, from an access point, a first synchronization signal having a first sequence and a second synchronization signal having a second sequence. The access terminal may then determine an offset in time between the first synchronization signal and the second synchronization signal, and determine a cell identifier group associated with the access point based on the offset.

Abstract: TDD devices may transmit using multiple antennas. First and second antennas having first and second receive conditions may receive a communication. In an aspect, first and second transmit conditions for the first and second antennas may be determined based on the first and second receive conditions. In an aspect, the first and second transmit conditions may be compared to select the first or second antenna for transmissions. In an aspect, the first and second receive conditions may be compared to select the first or second antenna for transmissions. In an aspect, first and second transmission conditioning values, which may determine transmission powers, may be determined based on the first and second receive conditions. A first transmission chain, associated with an active RAT or carrier, and a second transmission chain, associated with an inactive RAT or carrier, may be activated to send transmissions from the first and second antennas.

Abstract: The present disclosure describes methods and apparatuses for improved transport block decoding in devices capable of wireless communication, which may include user equipment and network entities. For example, the present disclosure presents methods and apparatuses for decoding a code block from a plurality of code blocks corresponding to a transport block, obtaining a reliability indicator that identifies a reliability of the decoding of the code block, comparing the reliability indicator to a reliability threshold, and determining whether to decode a subsequent code block from the plurality of code blocks based on the comparing. Furthermore, these methods and apparatuses may include determining not to decode at least one subsequent code block of the transport block where the comparing indicates that the reliability indicator is less than the reliability threshold. As such, device power is not unnecessarily consumed by decoding likely superfluous code blocks.
