Abstract: A User Equipment (UE) can receive Downlink Control Information (DCI) from a base station. The DCI can contain a Channel State Information (CSI) request on a physical control channel in a subframe of a first serving cell. The CSI request can direct the UE to perform CSI measurements for at least one aperiodic Channel State Information Reference Signal (CSI-RS) of a second serving cell. The UE can ascertain CSI-RS resources in a subframe of the second serving cell based on at least the DCI contents. The UE can determine CSI based on the ascertained CSI-RS resources. The UE can send the determined CSI to the base station.

Abstract: Operational and environmental efficiency in virtual radio access networks (VRANs) can be improved by offloading data traffic and/or control signaling between physical transmit points (TPs) of a virtual TP. This may allow one or more physical TPs of the virtual TP to be muted in the downlink or uplink direction, thereby reducing energy consumption. The offloading may be performed during relatively short time-intervals such that physical TP are muted for one or more transmission time intervals (TTIs) before being re-activated. The offloading may also be implemented over longer time-intervals in accordance with a traffic engineering (TE) policy. Further it is possible to re-activate a de-activated downlink transmitter of physical TP by monitoring wireless signals via an activated receiver of the physical TP.

Abstract: A method of self-healing a communication network is described herein. In particular, a plurality of message addresses can be registered with a publisher, and notifications from the publisher for the message addresses can be received. In addition, the notifications received from the publisher for the message addresses can be time-stamped. A notification interval for the message addresses can be monitored in which the interval may be based on a predetermined amount of time. The time-stamps of the received notifications can be compared to the notification intervals to determine whether a disruption in the receipt of the notifications for at least some of the message addresses has occurred. If a disruption has been determined to have occurred, the message addresses that have been affected by the disruption can be deleted. The deleted message addresses can then be re-registered with the publisher to restore the receipt of the notifications from the publisher for the affected message addresses.

Abstract: A method allows each individual node in the multi-node computing system to detect the topology of the computing system. Each individual node detects its own connections with neighboring nodes directly connected to the individual node, and sends out a topology packet on all of its interfaces with a local topology change indicator that increments with each topology packet sent out. Each individual node stores their own topology table with an entry for each node from which it has received a topology packet, including the local topology change number which enables the node to determine whether a received topology packet is more recent than data already stored in the topology table. Each node updates its topology table with new topology data, forwards new topology data, and sends back acknowledgements to a source node only upon receiving acknowledgements from all other nodes.
