Abstract: The present disclosure describes techniques and systems for handing over a connection of a user device, within a wireless network, based on qualities of downlink signals and qualities of uplink signals. These techniques and systems include a base station and a neighboring base station negotiating handover parameters, based on the qualities of downlink signals as detected by a user device and the qualities of uplink signals as detected by the base station and the neighboring base station. The base station and neighboring base station negotiate the handover parameters via an interface connecting the base station to the neighboring base station.

Abstract: This document describes techniques and apparatuses for a Fifth Generation New Radio (5G NR) enhanced Physical Downlink Control Channel (PDCCH). These techniques include a user device transmitting a request to a base station for a UE-specific PDCCH format. In aspects, the user device transmits an uplink Radio Resource Control (RRC) message or a Medium Access Control (MAC) Control Element (CE). The base station can then grant the user device a particular PDCCH format, based on the request, by using downlink RRC messages or a MAC CE. This allows the user device to identify the UE-specific PDCCH format and an appropriate aggregation level with which to decode messages on the PDCCH. These techniques reduce the amount of power consumed when decoding the messages on PDCCH in comparison to conventional techniques that rely on blind decoding.

Abstract: Techniques and apparatuses are described for neural network formation configuration feedback for wireless communications. A network entity (base station 120, core network server 302) determines a set (sets 2002, 2104) of deep neural network reference signals to send on a physical channel for measuring performance of deep neural networks, and/or a set of neural network formation configurations (sets 2004, 2106). The network entity communicates indications (indications 2030, 2102) of the set of neural network formation configurations and the set of deep neural network reference signals to a user equipment (UE 110). The network entity initiates transmission of each deep neural network reference signal of the set, and directs the user equipment to measure (outputs 2032, 2034, 2036, 2124, 2128, 2132) performance of a set of deep neural networks formed using the set of neural network formation configurations, and select one of the set of neural network formation configurations.

Abstract: This document describes techniques and apparatuses for base station location authentication. In particular, a base-station-location server 264 provides protection against a Global Navigation Satellite System (GNSS) spoofing attack or a cellular-network spoofing attack by auditing processed locations 504 of base stations 120 within a cellular network. The base-station-location server 264 maintains a list of authenticated base stations, generates a security key 321 for a base station 120 that is authenticated, and sends the security key 321 to the base station 120 in an authentication message 522. The authenticated base station 120 uses the security key 321 to generate an encrypted positioning reference signal that protects timing information and/or a location 504 of the base station 120. The encrypted positioning reference signal also enables a user equipment (UE) to determine that the base station 120 is authenticated by the base-station-location server 264.

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: The present disclosure describes methods and apparatuses for inter-radio access technology carrier (RAT) aggregation. In aspects, a user device (102) establishes a wireless link (106) for communicating with one or more base stations (104, 202) via a first component carrier (214) and a second component carrier (208, 220). The first component carrier uses a (RAT) having a first transmission time interval (TTI) and the second component carrier uses a second RAT having a second, different TTI. The user device receives user plane data via the second component carrier and analyzes the user plane data to determine whether data packets of the user plane data were successfully or unsuccessfully received by the user device (804, 806). The user device then transmits, via a next available uplink subframe or time slot of the first component carrier of the first RAT, a feedback communication based on which data packets were successfully received (808).

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: The present disclosure describes techniques and systems for beam search pilots for paging channel communications. In some aspects, a user device receives, from a base station of a wireless network, a beam search pilot on a beam. The user device determines that a signal quality of the beam search pilot meets a signal quality threshold. Based on this determination, the user device transmits, to the base station, an indication that the beam search pilot meets the signal quality threshold. The user device then receives a paging channel communication on the beam provided by the base station.

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: This document describes improvements in mobility for user equipment (UE) (110) between cellular and Wireless Local Area Networks (WLAN) (170) in fifth generation new radio (5G NR) wireless networks, as well as 3rd Generation Partnership Project Long-Term Evolution (3GPP LTE) or Evolved Universal Terrestrial Radio Access (E-UTRA) networks. A cellular-WLAN network interface is introduced to monitor and manage WLAN networks (170) and Access Points (160), and to facilitate handoffs of UE (110) between WLAN APs (160), between WLAN networks (170), and between WLAN networks (170) and cellular networks (140). The cellular-WLAN network interface enables an Access and Mobility Function (220) in a 5G network or a Mobility Management Entity (330) in an E-UTRA network to request information from UE (110) and WLAN APs (160), manage the operating configuration of WLAN APs (160), and initiate UE (110) handoffs.
