Abstract: The present disclosure describes techniques and systems to mitigate a power condition local to a user device by deactivating high-bandwidth transmission of data to the user device. While receiving multiple streams of data as part of high-bandwidth wireless communications, the user device determines a local power condition and sends a deactivation message that causes a base station to deactivate transmission of at least one of the multiple streams of data.

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.

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: The present disclosure describes techniques for, and systems that enable, inter-radio access technology spectrum sharing. For example, a wireless network provider can cause a legacy wireless network to share temporarily available communication resources with a new wireless network. By enabling the legacy wireless network to share its frequency spectrum with the new wireless network, the wireless network provider can temporarily expand a frequency spectrum of the new wireless network. By doing so, the wireless network can better utilize advantages of the new wireless network and provide a better experience to user devices equipped with the new communication technology.

Abstract: In aspects of downlink-only fifth generation new radio, a mobile communication device includes a radio frequency transceiver, a radio frequency receiver, and a processor and memory system to implement a radio control manager application that establishes an LTE anchor link with a base station using the LTE transceiver, establishes a 5G NR downlink from the base station to the mobile communication device using the radio frequency receiver, and manages the 5G NR downlink via an uplink of the LTE anchor link. In another aspect, a mobile communication device estimates channel conditions for a 5G NR downlink, selects a precoding matrix to beamform the 5G NR downlink, and provides an indication of the selected precoding matrix via the LTE anchor link.

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: The present disclosure describes methods and apparatuses for narrow-band communication. In some aspects, a base station determines a quantity of resource elements to allocate to a user device for wireless communication based on a state of the user device. The base station selects, from a resource block, resource elements for the user device that include the determined quantity of resource elements and a portion of subcarriers of the resource block. The base station then communicates, to the user device, an identification of the selected resource elements that includes respective frequencies and time locations of the selected resource elements within the resource block.

Abstract: Spectrum access allocation processes and systems are described in which multiple tiers of predetermined transmission powers are enforced, and where access is established by transmission at or below the lowest predetermined transmission power. The allocation processes include provisioning a wireless interface between a spectrum access system and a user equipment that is not registered with the spectrum access system. The wireless interface permits data transfer at or below a first predetermined power setting. A request to register the user equipment with the spectrum access system is transmitted to a spectrum access server. The spectrum access server receives a message from the spectrum access server indicating that the user equipment has been registered with the spectrum access system. The user equipment is controlled to transmit data at a second predetermined power setting that is greater than the first predetermined power setting.
