    Abstract: A wireless access point serves dynamic direction-of-arrival reception. An access point radio wirelessly receives a wireless signal that transports time-domain data. Access point circuitry determines uplink utilization for the access point radio. The circuitry transforms the time-domain data into frequency-domain data. The circuitry filters the frequency-domain data for one direction-of-arrival responsive to the uplink utilization. The circuitry synthesizes the time-domain data from the filtered frequency-domain data. The radio wirelessly receives another wireless signal that transports additional time-domain data. The circuitry determines a higher uplink utilization for the access point radio. The circuitry transforms the additional time-domain data into additional frequency-domain data. The circuitry filters the additional frequency-domain data for multiple directions-of-arrival responsive to the higher uplink utilization. The circuitry synthesizes the additional time-domain data from the filtered additional frequency-domain data.

    Abstract: A mobile communication device that performs self-testing. The device comprises a radio transceiver, a non-transitory memory, a processor, and a self-testing application stored in the non-transitory memory. When executed by the processor the self-testing application determines a location of the device, after determining the device location and within a predefined period of time, establishes a communication session via the radio transceiver with a self-test analysis server, and receives a self-test manifest from the self-test analysis server, where the self-test manifest identifies a self-test. The application further performs the self-test identified by the manifest, logs results of the self-test, stores the logged results in a memory of the device, transmits the logged results and the location of the device to the self-test analysis server, after transmitting the logged results and location of the mobile communication device, deletes the logged results from the mobile communication device, and closes the communication session.

    Abstract: Central Unit (CU) circuitry in a wireless data network serves wireless User Equipment (UE) with an integrated Packet Data Convergence Protocol (PDCP). The CU circuitry receives downlink data from a Fifth Generation New Radio (5GNR) Service Data Adaption Protocol (SDAP) component. The CU circuitry executes the integrated PDCP to route the downlink data from the 5GNR SDAP component to an Institute of Electrical and Electronic Engineers 802.11 (WIFI) Radio Link Control (RLC) component. The CU circuitry receives uplink data from the WIFI RLC component. The CU circuitry executes the integrated PDCP to route the uplink data from the WIFI RLC receive memory to the 5 GNR SDAP component.

    Abstract: In a wireless network, a Distributed Unit (DU) receives Uplink (UL) data from User Equipment (UE) and a Central Unit (CU) receives Downlink (DL) data for the UE. When DL-centric applications in the UE use the DL, the CU executes most network applications and the DU executes a few network applications. When the DL-centric applications use the UL, the DU executes the network applications and the CU transfers the UL data to the core. When UL-centric applications in the UE use the DL, the CU routes the DL data to the DU, and the DU executes the network applications. When the UL-centric applications use the UL, the DU executes a few network applications and the CU executes most network applications to route the data to the core. Advantageously, the DU and the CU are optimized to process UL/DL data for a user application based on whether the user application is UL-centric or DL-centric.

    Abstract: A wireless access point uses both Carrier Aggregation (CA) and Multi-User Multiple Input Multiple Output (MU-MIMO). In the wireless access point, processing circuitry determines when Radio Frequency (RF) signal strength for a User Equipment (UE) exceeds a CA threshold. Transceiver circuitry transfers data to the UE over wireless CA links when the RF signal strength exceeds the threshold. The transceiver circuitry transfers data to the UE over different wireless links when the RF signal strength does not exceed the threshold. The processing circuitry determines MU-MIMO load on the wireless access point. The processing circuitry increases the CA threshold when the MU-MIMO load increases. The processing circuitry decreases the CA threshold when the MU-MIMO load decreases.

    Abstract: A wireless relay receives user data from User Equipment (UE). In the wireless relay, a Proxy Mobile Internet Protocol (PMIP) Media Access Gateway (MAG) compresses the user data and transfers a PMIP packet having a packet header and the compressed user data. In the wireless relay, relay equipment compresses the packet header and wirelessly transmits the PMIP packet. A wireless network node wirelessly receives the PMIP packet, decompresses the packet header, and transfers the PMIP packet to a network gateway. In the network gateway, a PMIP Local Mobility Anchor (LMA) receives the PMIP packet, decompresses the user data, and transfers the user data.
