Patent number: 9820295Abstract: Coordination information for controlling base-station-to-base-station interference is transmitted from one radio network node (900) (e.g., an LTE eNodeB) to another, using certain parts of the TDD subframe. One example method, as might be implemented in a radio network node (900) such as an LTE eNodeB, includes the generating (1010) of a TDD coordination signal and the transmitting (1020) of the TDD coordination signal to one or more other radio network nodes.

Patent number: 9781037Abstract: Systems, methods, and computer-readable media provide for collection of statistics relating to network traffic between virtual machines (VMs) in a network. In an example embodiment, a virtual switch hosted on a physical server provides network address information of VMs deployed on the physical server to a virtual switch controller. The controller collects this network address information from each virtual switch under its control, and distributes the aggregate address information to each switch. In this manner, the controller and each switch within the controller's domain can learn the network address information of each VM deployed on physical servers hosting switches under the controller's control. Each virtual switch can determine a classification of a frame passing through the switch (e.g., intra-server, inter-server and intra-domain, or inter-domain traffic), and statistics relating to the traffic.Type: GrantFiled: September 15, 2015Date of Patent: October 3, 2017Assignee: Cisco Technology, Inc.Inventors: Suraj Nellikar, Maithili Narasimha

Patent number: 9762359Abstract: There is provided a method, a user equipment and a base station that is capable of enhancing network throughput by efficiently transmitting E-DCH HARQ Acknowledgement Indicator Channel (E-HICH) information in the radio network. The method comprises combining previous E-HICH information with current E-HICH information when a transmission interval of the previous E-HICH information fully overlaps with a compressed mode gap, and transmitting the combined E-HICH information in a transmission interval of the current E-HICH information. The UE is configured to transmit uplink data even if it is determined that the E-HICH information of the uplink data will not be received before a next uplink transmission interval. Both the previous E-HICH information and the current E-HICH information will be received in the transmission interval of the current E-HICH information. Therefore, the network throughput is effectively enhanced.Type: GrantFiled: January 10, 2013Date of Patent: September 12, 2017Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventor: Guowei Zhu
