Abstract: A user equipment (UE) device may communicate according to a new device category satisfying specified QoS (quality of service) requirements while also satisfying specified link budget requirements, and/or additional optimization requirements. The UE device may communicate with a cellular base station according to a first mode of operation associated with the new device category, and may switch to communicating with the cellular base station according to a second mode of operation associated with a second (pre-existing) device category in response to the link budget requirements exceeding a specified value and the quality of service requirements not being sensitive. The UE device may also switch to communicating with the cellular base station according to a third mode of operation associated with a third (pre-existing) device type in response to the link budget requirement not exceeding the specified value, or the QoS requirements being sensitive and a downlink throughput requirement exceeding a specified throughput value.

Abstract: Apparatuses, systems, and methods for a wireless device to detect intermodulation issues and configure a transmission scheme to remedy detected intermodulation issues. The wireless device may perform measurements on a downlink carrier while one uplink carrier is scheduled for the wireless device. The wireless device may also perform measurements on the downlink carrier while two uplink carriers are scheduled for the wireless device. The wireless device may provide information based on those measurements to a serving base station. The base station may determine that an intermodulation issue is occurring at the wireless device based on the information provided, and may configure the wireless device to use a single uplink carrier at a time based at least in part on the intermodulation issue.

Abstract: This disclosure relates to indicating capabilities of a user equipment to a base station while performing cellular communication. A user equipment (UE) may transmit capability information to a base station. The capability information may comprise a maximum transport block size (TBS) per transmission time interval (TTI) and an associated processing delay of the UE for a reference subcarrier spacing. Alternatively, the capability information may comprise a maximum throughput and associated processing delay of the UE. The base station may determine at least one of a maximum TBS per TTI or a number of parallel hybrid automatic repeat request (HARQ) processes to utilize in subsequent communications with the UE based on the capability information and a subcarrier spacing to be used for the subsequent communications.

Abstract: This disclosure relates to performing uplink cellular communication in unlicensed frequency bands using Wi-Fi preamble information. A wireless device may receive downlink control information from a cellular base station. The downlink control information may indicate an uplink transmit opportunity for licensed assisted access communication for the wireless device. A length of the uplink transmit opportunity may be determined. Licensed assisted access uplink communication may be performed during the uplink transmit opportunity. A Wi-Fi physical layer preamble may be transmitted as part of the licensed assisted access uplink communication. A type of the Wi-Fi physical layer preamble may depend at least in part on the length of the uplink transmit opportunity.

Abstract: A wireless communication device (UE) includes a cellular processor configured to conduct wireless communications according to a first radio access technology (RAT) in a first frequency band and in a second frequency band, wherein the first RAT is a cellular RAT, the first frequency band is in an unlicensed spectrum, and the second frequency band is in a licensed spectrum. In some embodiments, the apparatus includes a wireless local area network (WLAN) processor configured to conduct wireless communications according to a second RAT in the first frequency band. In some embodiments, the cellular processor and the WLAN processor are configured to couple to a common antenna for communications in the first frequency band. In some embodiments, the cellular processor may notify the WLAN processor when it is scanning and/or when it is assigned secondary component carriers in the first frequency band. In some embodiments, the WLAN processor may notify the cellular processor when it is transmitting. In some embodiments, the WLAN processor and/or the cellular processor may perform one or more actions in response to such notifications to improve coexistence in the first frequency band.

Abstract: Systems and methods that enhance radio link performance in a multi-carrier environment. A method may be performed by a UE that includes scanning a plurality of carrier components for a primary cell, determining a first bandwidth of the primary cell, scanning for a secondary cell, determining a second bandwidth of the secondary cell, determining a maximum aggregated bandwidth by combining the first bandwidth and the second bandwidth and when the maximum aggregated bandwidth exceeds a bandwidth capability of the UE, performing a cell selection procedure to select one of the primary cell or the secondary cell based on a higher of the first bandwidth and the second bandwidth.

The method can include an edge node in a wireless network sending a first RTP packet including a first real time data frame to a second edge node. The method can further include the edge node determining that a radio link condition is sufficient to support redundant transmission of real time data to the second edge node.
