Abstract: An example method for routing IPv6 link-local addresses in a network environment is provided and includes receiving a packet at a first switch from an attached first host in a virtual local area network (VLAN) associated with a virtual routing and forwarding (VRF) instance of a network environment, where the packet is destined to an Internet Protocol version 6 (IPv6) link-local address of a remote second host in the VLAN, and routing the packet at Layer 3 to a second switch, to which the second host is attached. In specific embodiments, the second switch routes the packet at Layer 3 to the second host if the VRF does not include duplicate IPv6 link-local addresses corresponding to the IPv6 link-local address of the second host; the second switch bridges the packet at Layer 2 to the second host if the VRF includes at least one duplicate IPv6 link-local address.

Abstract: A mobile terminal monitors a candidate set (Candidate Set) of L1/L2 control information. However, when a base station carries out signaling of a candidate set to each of all mobile terminals, the load on the base station from the viewpoint of radio resources becomes large. Furthermore, the amount of processing in performing a blind detection of each mobile terminal also increases. Therefore, the base station carries out a process of performing grouping of the above-mentioned mobile terminal which is a destination of transmission of the above-mentioned L1/L2 control signal, a process of allocating an L1/L2 control signal to be transmitted to a predetermined mobile terminal to the control channel elements included in a group to which the predetermined mobile terminal is belonging on the basis of attribution information about the mobile terminal.

Abstract: In one embodiment, a region anchor node may receive a unicasted route request (RREQ) for a target node. The region anchor node may then flood the RREQ to a region within which it resides. Subsequently, the region anchor node may receive one or more reactive routing route replies (RREPs) returned by the target node within the region. Based on the RREPs, the region anchor node may build one or more region routes from the region anchor node to the target node, and returns the one or more region routes to the originator node to cause the originator node to concatenate the one or more region routes and the unicast route of the original RREQ to form a path from the originator node to the target node.

Abstract: A base station communicates with a terminal, for which an uplink component carrier and downlink component carriers are configured. The base station adjusts a payload size of control information, transmitted in a downlink control channel, based on a basic payload size, and maps the control information onto a search space in at least one of the downlink component carriers. The basic payload size of the control information mapped onto a search space in a primary downlink component carrier is based on a number of information bits obtained from a bandwidth of the primary downlink component carrier, and on a number of information bits obtained from a bandwidth of the uplink component carrier. The basic payload size of the control information mapped onto a search space in a non-primary downlink component carrier is based on a number of information bits obtained from a bandwidth of the non-primary downlink component carrier.

Abstract: Systems and methods for selectively enabling Robust Header Compression (RoHC) for Voice over Internet Protocol (VoIP) calls in a cellular communications network are disclosed. In one embodiment, a data radio bearer for a VoIP call is established between a base station and a mobile terminal. During the VoIP call, a radio frequency parameter for the data radio bearer is monitored. When the radio frequency parameter for the data radio bearer satisfies a predefined coverage-based condition, the base station enables RoHC for the VoIP call. In one preferred embodiment, the radio frequency parameter is a Signal-to-Interference-plus-Noise Ratio (SINR) for the data radio bearer for the VoIP call, and the predefined coverage-based condition is a predefined SINR threshold below which the base station enables RoHC. By enabling RoHC in this manner, RoHC resources are selectively made available for those VoIP calls that will benefit most from increased cell coverage provided by RoHC.
