    Abstract: Embodiments disclosed herein relate to Random Access Channel (RACH) optimization and Automatic Neighbor Relation (ANR) use cases and requirements for 5G networks. For example, embodiments disclosed herein automatically configure RACH parameters and neighbor relations for 5G networks that can generate biggest saving in resource utilization for mobile operators. The RACH optimization disclosed herein can automatically configure the RACH parameters in a cell to achieve the optimal RACH performance by reducing the network access and handoff time, and minimize the failures. The Automatic Neighbor Relation (ANR) management disclosed herein can automatically create and update the neighbor relations that can generate biggest saving in resource utilization for mobile operators.

    Abstract: Technology for a user equipment (UE), operable for monitoring a physical downlink control channel (PDCCH) is disclosed. The UE can monitor a downlink (DL) control channel for DL control information (DCI) at a predetermined monitoring occasion, wherein the predetermined monitoring occasion has a periodicity of P slots or P symbols with an offset Os. The UE can monitor a downlink (DL) control channel for DL control information (DCI) at a predetermined monitoring occasion, wherein Os has an offset with respect to a first slot in subframe number zero (SFN #0). The UE can monitor a downlink (DL) control channel for DL control information (DCI) at a predetermined monitoring occasion, wherein P is a positive integer greater than zero.

    Abstract: Disclosed are embodiments of a user equipment (UE) configured to communicate in a 5G network and to perform authentication between an edge enabler client (EEC) of the UE and an edge configuration server (ECS) or an edge enabler server (EES) based on an architecture for authentication and key management for applications (AKMA). The techniques include performing primary authentication with the 5G network to obtain a KAUSF; generating a KAKMA and an A-KID; providing to the EEC the KAKMA and an EEC identifier (ID) for the EEC to generate a Kedge, the KAKMA and the EEC ID being used by the EEC to compute a MACEEC; and sending to the ECS or the EES an application registration request, the application registration request including the EEC ID, the MACEEC, and the A-KID.

    Abstract: The present disclosure generally relates to user interfaces and techniques for managing audio exposure using a computer system (e.g., an electronic device). In accordance with some embodiments, the electronic device displays a graphical indication of a noise exposure level over a first period of time with an area of the graphical indication that is colored to represent the noise exposure level, the color of the area transitioning from a first color to a second color when the noise exposure level exceeds a first threshold. In accordance with some embodiments, the electronic device displays noise exposure levels attributable to a first output device type and a second output device type and, in response to selecting a filtering affordance, visually distinguishes a set of noise exposure levels attributable to the second output device type.

    Abstract: Aspects of the subject technology relate to electronic devices having speakers and airflow sensors for the speakers. In one or more implementations, the airflow sensor may be formed, in part, by a mesh structure that spans a port in a housing of the electronic device. In one or more implementations, the airflow sensor may be formed, in part, by an exposed portion of a conductive trace of the speaker.

    Abstract: Systems and methods provide for enhanced HARQ-ACK feedback for PDSCH repetition transmission. A UE is configured to provide feedback ACK for PDSCH with repetitions less than scheduled repetition numbers. In response, the network adapts the PDSCH repetition numbers according to the channel condition to further optimize the overall system spectrum efficiency.

    Abstract: Embodiments described herein provide for a multi-device context store in which context attributes of multiple devices can be synchronized. A first device can transmit a predicate to a second device, where the predicate includes a condition associated with an attribute of a multi-device context store. Upon the occurrence of the condition at the second device, a notification and/or context update can be sent by the second device to the first device. The predicate can also include a code block to be executed upon the occurrence of the condition.
