Loop dampening in a computer network
In one embodiment, when a packet is received at a device in a network, the device may determine whether a time-to-live (ttl) value of the packet has expired. If the ttl value has not expired, the device forwards the packet to a next-hop device in the network.

Method of determining a channel state in coordinated multipoint transmission
In order to reduce the feedback overhead of channel state information in coordinated multipoint (comp) transmission, the present invention provides a method of determining a channel state in the comp transmission, wherein the serving base station receives first channel state information with the serving base station and second channel state information with each of coordinated base stations, fed back by a user equipment; informing each coordinated base stations of the corresponding second channel state information; precoding a first reference signal according to the first channel state information, and sending the precoded first reference signal to the user equipment on the communication resource commonly used with the coordinated base station, wherein the first reference signal is superimposed with precoded second reference signals respectively sent by each of coordinated base stations; receiving third channel state information fed back by the user equipment according to the superimposed reference signal, and determining a channel state of the coordinated multipoint transmission corresponding to the user equipment, according to the first, second and third channel state information.. .

Measurement of nodes in coordinated multipoint (comp) systems
Technology for enabling radio resource management (rrm) measurements in coordinated multi-point (comp) transmission and reception is disclosed. One method comprises sending, from an evolved node b (enb) to a user equipment (ue), an information element (ie) containing a list of measurement objects that define configurations of channel state information reference signal (csi-rs) based rrm measurements.

Method and system for implementing video conference and broadband mobile hotspot device
A method and system for implementing a video conference and a broadband mobile hotspot device are disclosed in the present document. The method includes: each broadband mobile hotspot device participating in the conference sending a local panorama video image and voice signals to a multipoint conference server; the multipoint conference server sending the received panorama video images and voice signals to other broadband mobile hotspot devices participating in the conference except a sender; and after receiving panorama video images and voice signals of the other broadband mobile hotspot devices participating in the conference, each broadband mobile hotspot device participating in the conference mosaicking the local panorama video image and the received panorama video images as a conference panorama video image, and synchronizing the conference panorama video image with the received voice signals to send to a terminal device participating in the conference under the broadband mobile hotspot device..
