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 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.

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.

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: The present disclosure describes techniques and systems for wireless communication via a mobile relay. These techniques may include a user device that determines that a transceiver is unavailable for communicating with a base station via a wireless connection. The user device then uses a mobile relay to communicate with the base station while the transceiver is unavailable. The mobile relay may be used for transmitting or receiving data from the base station. Additionally or alternatively, the mobile relay may participate in the wireless connection as an external resource of the mobile device or may establish an independent wireless connection with the 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.

A user equipment (110) uses an ACS for joint wireless communication between the user equipment (110) and multiple base stations (120) included in the ACS. The user equipment (110) receives a resource configuration for an ACS Disengaged-mode Reference Signal (ADRS). The user equipment (110) transitions to a disengaged mode (424) and receives the ADRS. The user equipment (110) determines that an updated ACS is required, transmits a message or a sounding signal indicating the need for the updated ACS, and in response, receives the updated ACS from a master base station (121).

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 methods, devices, systems, and means for an active coordination set for mobility management. A user equipment (110) evaluates a link quality measurement for one or more base stations (120) and determines to include at least a first base station of the base stations (120) in an Active Coordination Set (ACS). The user equipment (110) sends a message, including an indication to add the at least first base station (120) to the ACS, to an ACS Server (520) that causes the ACS Server (520) to store the ACS for the user equipment (110) and send a copy of the stored ACS to a master base station (121). The user equipment (110) communicates via one or more of the base stations (120) included in the ACS.

The described systems and methods include the UE determining that wireless-communication interferences proximate to the UE violate a criterion and sending, to the base station, a listen-before-talk request message that includes LBT control parameters. The base station then configures its wireless-communication components to perform downlink transmissions to the user equipment in a listen-before-talk mode that conforms to the LBT control parameters.

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. With this control, the network can balance the use of the licensed frequency band for wireless communication operations and radar-based applications. The network can further control operations of the user equipment 110's radar system to control an amount of interference that is present within the licensed frequency band. With permission from the network via a radar grant message 524, the radar system can utilize frequencies within the licensed frequency band for radar-based applications, such as gesture recognition, presence detection, collision avoidance, and so forth.
