Abstract: This document describes techniques and apparatuses for distributed network cellular identity management. In particular, a distributed-network cellular-identity-management (DNCIM) server includes a lookup table that stores and relates together a user-equipment (UE) public key associated with a UE private key, a core-network (CN) public key associated with a CN private key, and a subscriber identity. Using the DNCIM server, the UE and an authentication server respectively generate two different (e.g., asymmetric) cipher keys based on the UE private key and the CN public key, and the UE public key and the CN private key. The UE and the authentication server can also authenticate one another by referencing information in the lookup table of the DNCIM server. Using these cipher keys, the UE and the authentication server can establish secure communications with each other.

Abstract: This document describes methods, devices, systems, and means for user-equipment-coordination-set (404) control aggregation that facilitates more efficient control-plane signaling in comparison to conventional wireless communication systems. Overhead for control-plane signaling is reduced by communicating reports and control commands for the multiple user equipments (110) in the user-equipment-coordination-set (404) in a single message instead of communicating a single control message for each user equipment (110). Additionally, the user-equipment-coordination-set (404) uses joint-reception and joint-transmission, to increase the reliability of communicating reports and control commands, especially in the case of challenging radio communication conditions between a base station (121) and an individual UE (110) located near the edge of a cell provided by the vase station.

Abstract: Techniques and apparatuses are described for enabling base stations (121, 122) to coordinate for canceling cross-link interference (380). The techniques and apparatuses described herein overcome challenges that a single base station (121) might otherwise face in trying to compensate a reception (131) by the base station (121) for cross-link interference (382) from a transmission (132) by another base station (122). The techniques and apparatuses described herein enable the base stations (121, 122) to form coordination sets to exchange information to enable the base stations (121, 122) to accurately reconstruct cross-link interference (380) and ultimately cancel the cross-link interference (380) to improve link quality.

Abstract: This document describes monitoring and managing wireless backhaul integrated with mobile access in fifth generation new radio (5G NR) wireless networks. The techniques described employ an Integrated Backhaul-Access and Mobility Function (IB-AMF) to enable authorization of a base station to access a 5G network through another base station. The techniques described also monitor channel conditions and traffic loads to manage backhaul links and facilitate handovers of base station backhaul connections between other base stations.

Abstract: The present disclosure describes techniques and systems for wireless communications between a base station [120] and a user equipment [110] using an enhanced radio-resource control idle mode. The described techniques and systems enable a user equipment [110] to receive a radio-resource control release message [410] that includes a cell radio-network temporary-identifier and, in response, enter [415] the enhanced radio-resource control idle mode. While in the enhanced radio-resource control idle mode, the user equipment [110] may receive a message [420] in accordance with the cell radio-network temporary-identifier and present the received message.

Abstract: Techniques and apparatuses are described for machine-learning architectures for simultaneous connection to multiple carriers. In implementations, a network entity determines at least one deep neural network (DNN) configuration for processing information exchanged with a user equipment (UE) over a wireless communication system using carrier aggregation that includes at least a first component carrier and a second component carrier. At times, the at least one DNN configuration includes a first portion for forming a first DNN at the network entity, and a second portion for forming a second DNN at the UE. The network entity forms the first DNN based on the first portion and communicates an indication of the second portion to the UE. The network entity directs the UE to form the second DNN based on the second portion, and uses the first DNN to exchange, over the wireless communication system, the information with the UE using the carrier aggregation.

Abstract: The present disclosure describes techniques and systems for user device-initiated low-latency data transmissions to reduce a latency in transmitting low-latency data. These techniques may include a user device that autonomously determines to transmit low-latency data, then transmits the low-latency data over one or more resources of a wireless network for which transmission of the low-latency data is not scheduled.

Abstract: This document describes techniques and devices for communication of dual connectivity (DC) capability by user equipment (110) to a base station (120) and a core network (150) using signaling of a modification of the DC capability of the UE (110) at the physical layer (306) or the media access control layer (308) to reduce the latency of communicating the modification of the DC capability as compared to using Radio Resource Control layer (322) signaling. Signaling a modification of DC capability at the physical layer (306) or media access control layer (308) enables the UE (110) to more quickly respond to issues detected by the UE (110), such as thermal management or in-device coexistence interference, that may be mitigated by discontinuing DC communications.

Abstract: This document describes improvements in mobility management for user equipment (110) between a cellular network (202) and a WLAN network (206). A Cellular-WLAN Mobility Function (210) is introduced to manage routing of packet data over the cellular network (202) and the WLAN network (206) to the user equipment (110). The CWMF (210) enables the transfer of packet data context between the cellular network (202) and the WLAN network (206), improved handovers between the cellular network (202) and the WLAN network (206), Quality of Service (QoS) management of the WLAN network (206), and aggregation of cellular and WLAN bandwidths to improve data throughput for user equipment 110.

Abstract: This document describes mobility management of edge computing resources in fifth generation new radio (5G NR) wireless networks. The techniques described enable authorizing user devices to access edge compute servers that execute applications for the user device. The techniques described also enable the migration of applications of user devices between edge compute servers based on mobility changes of user devices in a wireless network, such as handovers of a user device between base stations in the wireless network.
