Joint-processing, including joint-transmission and/or joint-reception, by a user equipment-coordination set on behalf of a single user equipment, or by an Active Coordination Set of base stations with the single user equipment, can improve the link budget of Random Access Channel communications and facilitate network access for a user equipment at a greater distance from a base station or in the face of challenging channel conditions.

Abstract: Techniques and apparatuses are described for secondary cell-user equipment (SC-UE) handovers. In aspects, a base station provides, as a primary cell, primary cell services to a first group of user equipments (UEs) in a first base station-user equipment dual connectivity (BUDC) group. In implementations, the base station determines to perform an SC-UE handover that disconnects a first UE from a first secondary cell-user equipment (SC-UE) that provides a first secondary cell to the first BUDC group and connects the first UE to a second SC-UE that provides a second secondary cell to a second BUDC group. The base station directs the first SC-UE to release the first UE from the first BUDC group, and communicates, as the primary cell, control-plane information or user-plane data with one or more UEs in the first group of UEs that remain in the first BUDC group.

Abstract: Techniques and apparatuses are described for user equipment-coordination set, UECS, hybrid automatic repeat request, HARQ, that establish a HARQ timeline that is specific to the capabilities of a respective UECS. Compared to a single user equipment, UE, the HARQ timeline for a UECS depends on a number of factors, such as the joint processing capability in the UECS, latency of communication over a local wireless network between the UEs in the UECS, or the like. Based on its capabilities, the UECS can request uplink and/or downlink processing delay times or a UECS-specific HARQ timeline from a base station. The base station grants the uplink and/or downlink processing delay times or the UECS-specific HARQ timeline to the UECS in a layer-1, layer-2, or a layer-3 control message. The use of a UECS-specific HARQ timeline increases the reliability of HARQ signaling for uplink and downlink communication between the UECS and a base station.

Abstract: Techniques and apparatuses are described for enabling user equipment to coordinate for interference cancelation. In some aspects, base stations form a user equipment coordination set by pairing a UE of a base station with another UE of another base station. The UE receives, from the other UE, information regarding an uplink transmission of the other UE to the other base station, the information including I/Q samples for the uplink transmission. Based on the received information, the UE can model interference from the uplink transmission of the other UE to a reception of a downlink transmission by the base station to the UE. After the UE receives the downlink transmission, the UE cancels, based on the modeling of the interference, the interference to the received downlink transmission from the uplink transmission of the other UE. By so doing, receiver performance or link quality of the interference-canceling UE can be improved.

Abstract: This document describes techniques and devices for determining a machine-learning architecture for network slicing. A user equipment (UE) and a network-slice manager communicate with each other to determine a machine-learning (ML) architecture, which the UE then employs to wirelessly communicate data for an application. In particular, the UE selects a machine-learning architecture that provides a quality-of-service level requested by an application. The network-slice manager accepts or rejects the request based on one or more available end-to-end machine-learning architectures associated with a network slice that supports the quality-of-service level requested by the application. By working together, the UE and the network-slice manager can determine an appropriate machine-learning architecture that satisfies a quality-of-service level associated with the application and forms a portion of an end-to-end machine-learning architecture that meets the quality-of-service requested by the application.

Abstract: The present disclosure describes techniques and systems for user device-initiated bandwidth requests. In some aspects, a user device determines conditions related to communicating with a base station over a wireless connection. The user device selects, based on the determined conditions, a frequency bandwidth for communicating with the base station. The user device then transmits, to the base station, a request to communicate over the selected frequency bandwidth. In some implementations, the user device may receive, in response to transmitting the request, a resource grant allocating at least a portion of the selected frequency bandwidth for communicating over the wireless connection.

Abstract: The subject matter described herein provides systems and techniques to automatically configure a proximal device, such as a smart watch, a tablet, or any other smart device, based on configuration information sent from the user equipment (UE) to the proximal device when the local communications connection, such as a wireless connection, between the devices is weak. If it is determined that there is a weak local communications connection between the UE and the proximal device the UE may automatically send network configuration information to the proximal device. If it is determined that there is a weak local communications connection between the UE and the proximal device the UE may automatically turn on its mobile hotspot, and automatically send the mobile hotspot configuration information to the proximal device.

Abstract: This document describes techniques and apparatuses for optimizing a cellular network using machine learning. In particular, a network-optimization controller uses machine learning to determine an optimized network-configuration parameter that affects a performance metric of the cellular network. To make this determination, the network-optimization controller requests and analyzes gradients determined by one or more user equipments, one or more base stations, or combinations thereof. By using machine learning, the network-optimization controller identifies different optimized network-configuration parameters associated with different local optima or global optima of an optimization function, and selects a particular optimized network-configuration parameter that is appropriate for a given environment. In this manner, the network-optimization controller dynamically optimizes the cellular network to account for both short-term and long-term environmental changes.

The user device then receives a paging channel communication on the beam provided by the base station.

Abstract: The present disclosure describes techniques and systems for user device-initiated requests for resource configuration. In some aspects, a user device can detect one or more conditions related to communicating with a base station over a wireless connection. The user device selects, based on the conditions, a numerology configuration for communicating with the base station. The user device then transmits a request indicating the selected numerology configuration to the base station, which can then allocate resources to the user device based on the request. This may allow the user device to influence a resource configuration that is better suited for communication over one or more channels of the wireless connection.

Abstract: This document describes techniques and devices for controlling radar transmissions within a licensed frequency band. In particular, a network is given control over whether or not a user equipment 110 transmits a radar signal within at least a portion of one or more licensed frequency bands associated with coverage of the network.

Abstract: The present disclosure describes methods and apparatuses for beamforming for communication over preferred resources of a wireless network. A user device receives a signal from a plurality of antenna arrays of one or more base stations. The signal is transmitted, by the base stations, over a set of dedicated communication resources of a wireless network. Each of the base stations may dedicate a same set of resource elements for narrow-band communication with user devices outside of a standard range of a single antenna array. The user device determines a quality of the signal received over the dedicated communication resources and generates an index to identify preferred resources for communicating with the one or more base stations. The user device then communicates the index to the base stations to enable the base stations to establish a narrow-band wireless connection with the user device.
