Abstract: This document describes techniques that enable fast data-rate scaling. Using the described techniques, a user equipment (110) can detect trigger events that may be addressed by a data rate adjustment (402). In response to the trigger event, the user equipment can determine a data-rate scaling factor (404). The user equipment can transmit the data-rate scaling factor to a base station (120) that is providing a data rate negotiated between the user equipment and the base station and cause the base station to provide an adjusted data rate that is based at least in part on the data-rate scaling factor (406). When the data-rate scaling factor is transmitted via a Random Access Channel or a Physical Random Access Channel, the user equipment may adjust the data rate without waiting for an uplink grant, which can enable the user equipment to quickly mitigate operating conditions such as low battery capacity.

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, elements of a resource configuration for communicating with the base station. The user device then transmits a request indicating the selected elements of the resource configuration to the base station, which can then allocate resources to the user device based on the request. The elements of the resource configuration selected by the user device may include one or more of numerology configuration, mini-slot configuration, or a schedule for uplink and downlink OFDM symbols within a resource of the wireless network. 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: The present disclosure describes methods and apparatuses for opportunistic 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.

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 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.

The techniques described enable the use of WLAN network slices (216c) with cellular networks (202) and mobility management of user equipment (102) between cellular networks (202) and WLAN networks (206). An Access and Mobility Function-Aggregation Proxy (AMF-AP) (218) connects one or more WLAN networks (206) to the cellular core network (110) of a network operator via the Access and Mobility Function (AMF) (212) in the core network (110). The AMF-AP (218) acts as a proxy and a firewall to protect the AMF (212) and other entities in the cellular core network (110) from malicious actors.

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.

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.

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: The present disclosure describes techniques and systems for post-grant beam tracking. These techniques may include a user device receiving a pilot transmission between receiving an uplink grant and transmitting associated data. The pilot transmission may assist the user device in selecting a transmission configuration, such as selection of a beam or selection of transmitting antennas, for transmitting the associated data. Further, the user device may receive the pilot transmission, from a base station, over a beam tracking pilot channel of a wireless connection with the base station.

Abstract: The present disclosure describes methods and apparatuses for user device-requested downlink pilots. Downlink pilots can be used by the user device to estimate a channel over which the user device receives data from a base station, thus improving error rates for decoding the data. Some examples of downlink pilots include demodulation reference signals (DM-RS), channel state reference signals (CS-RS), or sounding reference signals (SRS). By enabling the user device to request downlink pilots, the base station can transmit downlink pilots that are customized to provide reference signals with desired characteristics, such as positions within a frequency-time domain of the channel over which the user device receives data from the base station. The customized downlink pilots can enable the user device to better use reference signals to successfully receive and decode data from the base station.

The user device determines a current operating condition for a wireless communication link and based on the current operating condition, selects a configuration for one or more air interface resources, each air interface resource being selected to transmit a phase-tracking reference signal. The user device transmits a request that includes the selected configuration to a base station and receives, from the base station, the one or more air interface resources that each includes a phase-tracking reference signal.

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 methods, devices, systems, and means for user equipment-initiated beam search for fifth generation new radio. A user equipment (110) determines that a first beam being used for wireless communication between the user equipment (110) and a base station (121) is unsatisfactory for communication. The user equipment (110) transmits uplink beam-scan pilots that cause the base station (121) to select a second beam for wireless communication. The user equipment (110) receives a beam scan response message from the base station (121) and establishes wireless communication with the base station (121) on a second beam based on information included in the received beam scan response message.
