Abstract: There may be a gap between the time a beam pair link (BPL) impacted by a beam failure (BF) event is deactivated and the time a replacement BPL is activated and becomes fully functional at a UE. The gap may be called a blackout period. A base station may not know the blackout period and may continue transmitting to the UE on the impacted BPL during the blackout period. This may result in a transmission failure. Disclosed herein are apparatus and methods for determining a blackout period associated with a beam failure (BF) event and communicating a blackout indication to a base station, the blackout indication including the blackout period.

Abstract: Wireless communications systems and methods related to providing user interfaces to inform a user of an antenna signal blockage at a wireless communication device are provided. A wireless communication device receives information associated with at least one antenna of the wireless communication device indicating that a signal path of the at least one antenna is at least partially blocked by an object. The wireless communication device outputs, via a user interface of the wireless communication device, an indication that the signal path of the at least one antenna is at least partially blocked.

Abstract: A beam failure caused by an event initiated by the UE such as folding of the UE or shutting down of a UE antenna penal may be predictable. Accordingly, the UE may declare a beam failure detection (BFD) without going through a potentially long detection procedure. Disclosed herein are apparatus and methods for detecting beam failure and terminating BFD earlier than the current DFD process would have. The method may include identifying a beam failure (BF) event at the UE that impacts at least one beam pair link (BPL) and communicating a request to an associated base station to stop communicating on an impacted beam pair link, without going through an entire BFD process.

Abstract: Methods, systems, and devices are described for wireless communication at a user equipment (UE). A wireless communications system may improve UE discovery latency by dynamically selecting and switching beam forming codebooks at the millimeter wave base station and the wireless device. Selecting an optimal beam forming codebook may allow the wireless communication system to improve link margins between the base station without compromising resources. In some examples, a wireless device may determine whether the received signals from the millimeter wave base station satisfy established signal to noise (SNR) thresholds, and select an optimal beam codebook to establish communication. Additionally or alternately, the wireless device may further signal the selected beam codebook to the millimeter wave base station and direct the millimeter wave base station to adjust its codebook based on the selection.

Abstract: A method, an apparatus, and a computer program product for operating a user equipment (UE) are provided. The apparatus determines a first coarse set of beamforming paths between the UE and a first millimeter wave base station (mmW-BS), receives on a first set of narrow beamforming paths close to a first beamforming path within the first coarse set of beamforming paths, requests the first mmW-BS to transmit on a second set of narrow beamforming paths close to a second beamforming path within the first coarse set of beamforming paths when a signal quality of the first beamforming path and the first set of narrow beamforming paths are less than a first threshold, and communicates through one of the second beamforming path or a path within the second set of narrow beamforming paths.

Abstract: Técnicas para la comunicación inalámbrica. Un método para la comunicación inalámbrica en un equipo de usuario (UE) puede incluir la recepción de una secuencia de formación de haces transmitida por un dispositivo de acceso a la red en una pluralidad de haces de transmisión, la identificación, con base, por lo menos en parte, en la secuencia de formación de haces recibida, de uno o más conjuntos de múltiples haces que son compatibles con por lo menos una configuración para el enrutamiento de señales entre submatrices de antenas del UE y las unidades transceptoras (TXRU) del UE, y la transmisión, al dispositivo de acceso a la red, de una indicación de los uno o más conjuntos identificados de múltiples haces. Un método para la comunicación inalámbrica en el dispositivo de red puede incluir la transmisión de la secuencia de formación de haces, la recepción de la indicación, y la selección, con base, por lo menos en parte, en la indicación recibida, de conjunto de múltiples haces de los uno o más conjuntos de múltiples haces para utilizarlos para comunicarse con el UE.
