Abstract: A method is provided to establish a path in an optical domain to couple first and second IP routing domains for use by a VPN. A network controller (NC) receives an optical path setup command and, in response, determines an optical path ID identifying an optical path. The NC sends a mapping command to a domain controller (DC) associated with the first IP routing domain and receives routing information that includes a VPN label. The NC sends a forwarding command including the routing information to a DC associated with the second IP routing domain, the forwarding command configured to cause a termination point in the second IP routing domain to forward a packet to the optical path when the packet comprises elements of the routing information.

Abstract: Methods and apparatus for operating a virtual node in a LAG that includes a first virtual node and a second virtual node are disclosed. The first virtual node includes at least a first fellow node and a second fellow node. In one exemplary method, the first fellow node receives, from the second virtual node, first control information comprising a system ID and first configuration information associated with the LAG. The first control information is compared with reference configuration information representing previously established expected configuration information associated with the LAG. Based on that comparison, and at least one additional criterion, a split brain condition may be determined to exist in the LAG. In a complementary fashion, a fellow node of the second virtual node may be configured to alter its transmitted configuration information depending on whether it is able to communicate with its fellow node in the second virtual node.

Abstract: A scheduling apparatus and a scheduling method, wherein the amount of signaling for frequency resource allocation information can be reduced while maintaining system throughput performance. In a base station apparatus (100), a scheduling section (113) allocates frequency resources to frequency allocation target terminals based on set frequency allocation units, and a frequency allocation parameter setting section (112) adjusts the set frequency allocation units set in the scheduling section (113) based on cluster numbers. Due to this, in each cluster number, frequency resources can be allocated based on the most suitable frequency allocation units with respect to the signaling bit number. As a result, the amount of signaling for frequency resource allocation information can be reduced. Further, system throughput can be maintained by making the cluster number, which is a parameter having little effect on system throughput, a setting parameter for frequency allocation units.

Abstract: Certain aspects of the present disclosure relate to techniques for reducing the decoding complexity for low cost devices (e.g., low cost UEs). One technique may include simplifying the PDCCH format. This may include generating a compact DCI format for transmitting DCI to a low cost device. The compact DCI format may correspond to at least one standard DCI format used by a regular UE and may comprise a reduced number of bits when compared to the standard DCI format. Another technique may include reducing the number of blind decodes. This technique may include selecting a set of resources for transmitting DCI from a limited set of decoding candidates, such that a receiving low cost device need only perform blind decodes for the limited set of decoding candidates.

Abstract: Devices and methods for synchronized group messaging in a wireless communication system are described. Multicast transmissions, such as those in a dense network, can cause significant medium usage because same multicast packet is likely sent by multiple APs at different time. Medium usage in such implementations may be redundant. As such, the transmission medium is not used optimally. Devices and methods which coordinate and align group messages (e.g., multicast packets) amongst APs are described. Each AP may be configured to transmit identical packets at the same time. Therefore, medium usage can be reduced, while the range can be extended due to accumulated energy from APs.
