Abstract: Disclosed are systems and methods for generating a bit-indexed forwarding table (BIFT) that includes a plurality of entries, each of which corresponds to a bit position of a number of bit positions. Each such bit position represents an egress network node of a plurality of egress network nodes. The BIFT is generated from an existing BIFT that includes a number of existing BIFT entries. Further, the generating configures the BIFT to be used in forwarding a packet to one or more of the egress nodes, based at least in part on a bit string in the packet. In one embodiment, the generating includes selecting a bit position of the plurality of bit positions as a selected bit position, creating an entry of the plurality of entries, and converting an existing BIFT entry of the plurality of existing BIFT entries to the entry of the plurality of entries.

Abstract: Functionality for creating a bit routing table for use in a bit-indexed explicit replication (“BIER”) environment in disclosed herein. In one embodiment, this functionality includes receiving information from a host, and determining whether the information comprises a MAC address that is a bit-indexed explicit replication (“BIER”) MAC address. In response to determining that the information comprises a BIER MAC address, this functionality creates an entry corresponding to the MAC address in a bit routing table. This functionality also analyzes the information to determine a bit position that is associated with the host, and also determines a port via which the host is reachable. The functionality updates the bit routing table by storing information identifying the bit position and the port in the entry, such that the bit position and the port both correspond to the MAC address. This functionality can be used to route packets in a BIER environment.

Abstract: Various systems and methods for performing bit indexed explicit replication (BIER) using IPv6. For example, one method involves receiving, at a node, a packet that includes an IP header. The packet also includes a multicast forwarding entry. The method also involves comparing the multicast forwarding entry with forwarding information stored by the node and selecting a neighbor based on the comparing. The method further includes forwarding the packet to the neighbor.

Abstract: A wireless communication base station device which makes it possible to provide a base station, terminal and CCE allocation method capable of reducing the number of times blind decoding of a terminal is performed, without increasing the CCE block rate, even when a plurality of unit bands are set in a terminal. In this device, a search space setting section (103) sets in each of a plurality of unit bands a common search space in respect of a terminal which is communicating using the plurality of unit bands and other terminals, and sets in each of the plurality of unit bands an individual search space in respect of the terminal. An allocation section (106) allocates control information solely to CCEs within the common search spaces set in specified unit bands among the plurality of unit bands, or solely to CCEs within individual search spaces set in specified unit bands.

Abstract: For paging user devices that are link budget limited (LBL), a base station transmits a special ID that is used by said devices to identify a paging frame and/or a paging occasion. When transmitting a paging message for an LBL device, the base station may use: (a) larger aggregation and larger CFI (than conventionally allowed) and (b) a larger number of resource blocks (than conventionally allowed) for paging payload. If paging messages for LBL devices saturate the paging frame capacity, the base station may allocate a plurality of special IDs. If paging messages for LBL devices and/or other data transfers saturate network capacity, at least a subset of the LBL devices may be directed to enter a connected-state discontinuous reception (DRX) mode, wherein those devices will remain in connected mode and periodically check for resource allocations. Paging payload information may be repeatedly transmitted in successive subframes, to support soft combining.
