Abstract: Methods and apparatus are disclosed for monitoring a Maintenance Association (MA) for Connectivity Fault Management (CFM) in a network supporting Equal Cost Multiple Paths (ECMP). A set of ECMP paths is generated for sending data between endpoints in the network. Furthermore, a set of ECMP MAs is created that are used for monitoring the generated ECMP paths between the endpoints. The created set of ECMP MAs is subsequently used for sending monitoring packets. ECMP path MAs therefore conform to existing CFM operation and are compatible with both ECMP point to point path MAs and ECMP multipoint path MAs.

Abstract: In a cellular communication system, pre-coding MIMO parameters are assigned for transmission of device-to-device (D2D) signals between D2D mobile devices to minimize interference at unintended recipient devices (receiving proximate devices). The pre-coding MIMO parameters are transmitted from a base station to a transmitting D2D mobile device over a subset of defined downlink cellular communication resources defined by a communication specification for downlink transmission from base stations to mobile wireless devices. The pre-coding MIMO parameters are determined based on channel characteristics of at least an Interference channel where the Interference channel is between a D2D transmitting device and a proximate receiving mobile device (unintended recipient device). The pre-coding MIMO parameters are determined to facilitate interference management at the receiving proximate mobile device when the pre-coded transmission signal is received through the interference channel.
