Abstract:
In order to overcome problems that a UE may face in determining a default beam for communication with the base station during a COT, a method, apparatus, and computer-readable medium are provided for a base station to indicate to the UE which CORESET(s), QCL assumptions, UL resources, and/or spatial relationships are selected for a COT. A UE receives, from a base station, an indication corresponding to a COT. The indication is for at least one of a set of CORESETs, a set of QCL assumptions, a set of UL resources, or a set of spatial relations for determining a default beam. The UE determines the default beam from the base station for use during the COT based on the indication. The UE transmits or receives a transmission using the default beam.
Abstract:
Various aspects described herein relate to communicating using dynamic uplink and downlink transmission time interval (TTI) switching in a wireless network. A notification can be received from a network entity of switching a configurable TTI from downlink communications to uplink communications. The configurable TTI can be one of a plurality of TTIs in a frame structure that allows dynamic switching of configurable TTIs between downlink and uplink communications within a frame. Additionally, uplink communications can be transmitted to the network entity during the configurable TTI based at least in part on the notification.

Abstract:
Methods, systems, and devices are described for wireless communication. A device may use enhanced reporting mechanisms to support control information reporting on shared spectrum. In some cases, a device may utilize enhanced component carriers (eCCs) for data transmissions. In one example, the device may transmit control information (e.g., ACK/NACK, CSI, etc.) to a corresponding device using a CCA exempt transmission (CET). In another example, a device may report control information quasi-periodically. For instance, a device may be assigned a specified interval and a control feedback window for reporting control information (e.g., CSI). The window may provide a duration prior and subsequent to the specified interval during which a UE may transmit control information. For example, the device may perform a CCA reserving the channel for a duration that does not include the specified interval but may transmit feedback information based on determining the specified interval falls within the assigned window.
Abstract:
The disclosure provides for detecting interference in wireless communications. A wireless devices may receive an interfering signal on a portion of unlicensed spectrum. The wireless device may perform cyclic autocorrelation on the interfering signal to determine one or both of a cyclic prefix length and a symbol period. The wireless device may determine a radio access technology of the interfering signal based on one or both of the cyclic prefix length and the symbol period. In an aspect, the wireless device may further transmit an interference report including information regarding the interfering signal including the cyclic prefix length, symbol period, identified radio access technology, or packet length.
Abstract:
Methods, systems, and devices for wireless communication are described. A base station may employ a multiplexing configuration based on latency and efficiency considerations. The base station may transmit a resource grant, a signal indicating the length of a downlink (DL) transmission time interval (TTI), and a signal indicating the length of a subsequent uplink (UL) TTI to one or more user equipment (UEs). The base station may dynamically select a new multiplexing configuration by, for example, setting the length of an UL TTI to zero or assigning multiple UEs resources in the same DL TTI. Latency may also be reduced by employing block feedback, such as block hybrid automatic repeat request (HARQ) feedback. A UE may determine and transmit HARQ feedback for each transport block (TB) of a set of TBs, which may be based on a time duration of a downlink TTI.

Abstract:
Para superar los problemas que un UE puede enfrentar para determinar un haz predeterminado para comunicación con la estación base durante un COT, se proporciona un método, aparato y medio legible por computadora para que una estación base indique al UE qué CORESET, suposiciones QCL, recursos UL y/o relaciones espaciales se seleccionan para un COT. Un UE recibe, de una estación base, una indicación correspondiente a un COT. La indicación es para al menos uno de un conjunto de CORESET, un conjunto de suposiciones QCL, un conjunto de recursos UL o un conjunto de relaciones espaciales para determinar un haz predeterminado. El UE determina el haz predeterminado de la estación base para su uso durante el COT con base en la indicación. El UE transmite o recibe una transmisión usando el haz predeterminado
