Abstract: Various methods and devices are provided to address the need for improved dual connectivity. For example, a network node (500) in a primary network includes a processing unit (501) and an interface unit (510), which includes a network interface (511) for communication with other network devices. The processing unit is communicatively coupled to the interface unit and configured to receive, from a user equipment (UE) via the interface unit, a secondary Internet Protocol (IP) address for the UE, the secondary IP address being associated with a secondary network of the UE. The processing unit is also configured to initiate via the interface unit the establishment of at least one tunnel to bridge the network node and the UE via the secondary network.

Abstract: Embodiments are described herein to provide improvements to known network interference cancellation techniques. One general approach involves a first network node attempting (801) to decode a received signal which includes signaling from a first wireless device transmission and at least one interfering transmission. If the first network node is unsuccessful in attempting to decode the received signal, it is determined (802) whether it would be cost effective to obtain decoded signaling from a serving network node of a wireless device that corresponds to the at least one interfering transmission. If (803) it is determined to be cost effective, the decoded signaling that corresponds to the at least one interfering transmission is requested.

Abstract: The present disclosure generally discloses an interference mitigation capability. The present disclosure discloses use of dirty paper coding in a wireless communication network in order to mitigate interference in the wireless communication network. The wireless communication network may be a heterogeneous wireless communication network, where heterogeneity may be based on wireless access device technology type, wireless access device transmit power, or the like. For example, the wireless communication network may be a heterogeneous wireless communication network including a first type of wireless access device (e.g., a small cell device, such as a metro cell, microcell, picocell, femtocell, or the like) and a second type of wireless access device (e.g., a large cell device, such as a macro cell), where the first type of wireless access device is configured to use dirty paper coding to mitigate interference from the second type of wireless access device.
