Abstract: Techniques for communicating on multiple carriers in a wireless communication network are described. In an aspect, different transmit power levels may be used for different carriers to mitigate interference. A first base station may be assigned one or more carriers among multiple carriers available for communication. A second base station may be assigned one or more carriers not assigned to the first base station. Each base station may communicate on each assigned carrier at a first (e.g., full) transmit power level and may communicate on each unassigned carrier at a second (e.g., lower) transmit power level lower. The first and second base stations may belong in different power classes or support different association types. In another aspect, control information may be sent on a designated carrier to support communication on multiple carriers. In yet another aspect, a base station may broadcast bar information indicating the status of carriers.

Abstract: In one embodiment, an autonomous system border router (ASBR) advertises a same forwarding label for received advertised routes of a merging context that were advertised with a same forwarding label for the ASBR to use when sending corresponding packets. An ASBR receives via a routing protocol from a particular router in the same autonomous system, a plurality of same-labeled received routes advertised with a same first forwarding label within a merging context. In response to each of the plurality of same-labeled received routes having the same first forwarding label to use to forward packets to the particular router and being in the same merging context, the ASBR determines a merged forwarding label and advertises to a peer ASBR in another autonomous system (AS) each of the plurality of same-labeled received routes with the merged forwarding label for the peer ASBR to use to forward packets to the ASBR.

Abstract: The disclosure describes techniques that enable a network device to determine a confidence level for a network alarm and provide information indicative of the confidence level to other devices. For example, a network device may experience any number of conditions that cause the network device to output an alarm. In addition to or instead of simply sending out the alarm, the network device may perform operations to determine a confidence level associated with the alarm. For instance, the network device may determine whether the conditions that caused the alarm continue or whether the conditions can be validated. The network device may output information indicative of the confidence level.

Abstract: A Common Public Radio Interface (CPRI) link involves using a protocol stack having a CPRI layer and an emulation layer to emulate a point to point link, to enable the CPRI link to operate over a packet switched network. The emulation layer can be a pseudowire emulation which encapsulates multiple CPRI frames in a packet with overhead. A multiplexing layer such as Internet Protocol (IP) or Multiprotocol Label Switching (MPLS) can be used, for sending the packet over an Ethernet network. The usual need for a point to point infrastructure for the CPRI link can be avoided and the CPRI link can be implemented over more complex but usually cheaper packet networks, thus reducing costs or enabling more widespread application over existing packet networks. This applies whether the packet network is dedicated to the CPRI link, or shared with other packets. It can be useful for distributed radio base stations.
