Abstract: Systems, methods, and processing nodes for communicating with a wireless device via at least two access nodes include communicating with a wireless device via at least two access nodes includes receiving, at a relay access node coupled to a donor access node, downlink data intended to be transmitted to an end-user wireless device attached to the relay access node; determining that a signal condition at the relay access node meets a criteria; and in response to determining that the signal condition meets the criteria, forwarding the downlink data to the donor access node. The donor access node transmits the downlink data to the end-user wireless device, and the relay access node maintains a control channel with the end-user wireless device.

Abstract: Mitigating interference in such potential interference areas of a wireless communication network includes determining that a first sector associated with a first wireless air interface and configured with a first subcarrier spacing is facing a second sector associated with a second wireless air interface and configured with a second subcarrier spacing, wherein the first and second subcarrier spacings are different, and assigning resources towards the second sector in a different order than resources assigned to the first sector.

Abstract: Systems, methods, and processing nodes for communicating with a wireless device via at least two access nodes include receiving, at a gateway node, data addressed to a first network address of the wireless device, transmitting, via a donor access node, a first portion of the data within a first bearer addressed to a second network address of the wireless device, and transmitting, via a relay access node wirelessly coupled to the donor access node, a second portion of the data within a second bearer addressed to a third network address of the wireless device.

Abstract: Scheduling full-duplex transmissions includes configuring adjacent time slots of an air interface resource with different ratios of uplink portions, downlink portions, and flexible portions, scheduling transmissions in each adjacent time slot based on whether or not the transmissions are latency-sensitive or delay-sensitive or control transmissions. The uplink portions, downlink portions, and flexible portions comprise symbols within time slots of a subframe, and can vary based on a numerology. The flexible portions are symbols configured to simultaneously transmit uplink data and downlink data.

Abstract: Dual connectivity operations described herein include splitting a PDU into at least first and second portions of data addressed to or from first and/or second network addresses of a wireless device respectively, and modifying a source/destination address of the second portion of data from the first network address to the second network address in the downlink direction, and from the second network address to the first network address in the uplink direction. Uniquely-marked bearers set up between relay access nodes and donor access nodes (and gateways associated therewith) enable transmission of portions of data to and from the different network addresses.

Abstract: Systems, methods, and processing nodes are related to preventing message overloading in a wireless network. The method includes establishing, by the access node, the wireless connection with the wireless device. The method also includes forwarding, from the access node to a controller node, a network connection message from the wireless device. The network connection message requests connection to network services of the wireless network. Additionally, the method includes receiving, at the access node from the controller node, a message indicating that the wireless device is denied access to the network services. Also, the method includes terminating, at the access node, the wireless connection with the wireless device in response to receiving the message. The method further includes limiting, at the access node, an establishment of future wireless connections with the wireless device in response to receiving the message.
