Abstract: Cuando un UE en una primera celda que opera en una primera frecuencia intenta descubrir otro UE en una segunda celda que opera en una segunda frecuencia, el UE en la primera celda puede necesitar monitorear constantemente la comunicación en la segunda frecuencia para descubrir el UE en la segunda. celular, lo que puede no ser deseable. De acuerdo con un aspecto de la descripción, el aparato recibe, en una primera frecuencia de un primer canal desde una primera estación base que da servicio a una primera celda, información de descubrimiento asociada con una segunda frecuencia de un segundo canal correspondiente a una segunda celda, donde la primera la frecuencia es una frecuencia de enlace descendente (DL) y la segunda frecuencia es una frecuencia de enlace ascendente (UL). El aparato descubre, en base a la información de descubrimiento recibida, uno o más UE en la segunda frecuencia del segundo canal. (Traducción automática con Google Translate, sin valor legal)

Abstract: Low latency enhancements for communication systems, including autonomous driving and/or selection scenarios, are provided. A method for communication includes monitoring communication resources in a communication system, determining a set of candidate resources to use for subsequent transmission of information within a time window such that the time window is minimized based on a desired communication latency parameter that considers at least one or more of communication channel congestion and a priority of transmission, determining a set of lowest energy resources from the set of candidate resources, selecting a low energy resource from the set of lowest energy resources, and transmitting data on the selected low energy resource. Other aspects, embodiments, and features are also claimed and described.

Abstract: Certain aspects of the present disclosure provide techniques for half-duplex handling with system-wide feedback resources. Embodiments include determining, for a first feedback resource corresponding to a first time period, that the wireless node has a scheduled feedback transmission and a scheduled feedback reception on shared frequency resources. Embodiments include selecting one of the scheduled feedback transmission or the scheduled feedback reception based on a rule. Embodiments include using the feedback resource to perform the selected one of the scheduled feedback transmission or the scheduled feedback reception.

Abstract: Improvements may be made for the Channel Busy Ratio, CBR, based congestion control considering different technologies, types of radio resources, and priorities of different packets. The apparatus may be a User Equipment, UE. The UE determines an energy-based channel busy ratio (CBR) based on a number of probes on a set of radio resources having respective energy levels greater than an energy threshold. The UE performs congestion control based on the energy-based CBR by adjusting at least one transmission parameter of one or more transmission parameters or transmission power of the UE based on the energy-based CBR.The adjusting may be carried out taking into account a usage limit, or CBR limit. In addition, the UE may detect that a second technology different from a first technology is also using the channel, and in addition consider a decode-based CBR for the purpose.

Abstract: Methods, systems, and devices for wireless communications are described. A first device may identify that a first set of transmission resources in a transmission time interval (TTI) has a higher priority at a second device than a second set of transmission resources in the TTI. The first device may identify that a message is to be transmitted from the first device to the second device via the TTI and process the message into a bit sequence based on the identification of the second set of transmission resources in the TTI, where the processing increases a likelihood that systematic bits of the message are received at the second device despite presence of the second set of transmission resources in the TTI. The first device may transmit the bit sequence to the second device via the TTI.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems (e.g., sidelink systems, such as vehicle-to-everything (V2X) systems), wireless devices may perform dynamic resource reservations to schedule packet transmissions (e.g., data packet transmissions). Different packets may correspond to different priority levels. To support flexible resource reservation for high priority packets, wireless devices may implement techniques for preempting lower priority reservations. For example, a wireless device may identify reservations for transmitting different packets during a same transmission time interval (TTI). The device may determine whether a first or second packet has a higher relative priority and may communicate in the V2X system during the TTI according to the relative priorities. For example, a device that reserved the TTI for the lower priority packet may refrain from transmitting the packet during the TTI, while a device that reserved the TTI for the higher priority packet may transmit the packet.
