  • Patent number: 10374770
    Abstract: Embodiments of the present disclosure provide an uplink information demodulation method, an apparatus, and an uplink information demodulation system. and relate to the field of communications technologies. After an MCS index is selected for a terminal device, reduction processing is performed on the MCS index according to a preset MCS index reduction exponent, a reduced MCS index is indicated to the terminal device, frequency offset estimation is performed on the terminal device by using a recorded historical frequency offset value, and a PUSCH sent by the terminal device according to the reduced MCS index is demodulated after the frequency offset estimation. A frequency offset value is determined by using the prerecorded historical frequency offset value, so that the frequency offset value does not need to be determined in an existing manner of adding a DM-RS symbol to a 0.5-millisecond TTI.

  • Patent number: 10250685
    Abstract: Techniques for creating layer 2 (L2) extension networks are disclosed. One embodiment permits an L2 extension network to be created by deploying, configuring, and connecting a pair of virtual appliances in the data center and the cloud so that the appliances communicate via secure tunnels and bridge networks in the data center and the cloud. A pair of virtual appliances are first deployed in the data center and the cloud, and secure tunnels are then created between the virtual appliances. Thereafter, a stretched network is created by connecting a network interface in each of the virtual appliances to a respective local network, configuring virtual switch ports to which the virtual appliances are connected as sink ports that receive traffic with non-local destinations, and configuring each of the virtual appliances to bridge the network interface therein that is connected to the local network and tunnels between the pair of virtual appliances.

  • Patent number: 10236934
    Abstract: Embodiments of the invention provide multiple cyclic prefix lengths for either both the data-payload and frame control header or only the data payload. Frame control header (FCH) and data symbols have an associated cyclic prefix. A table is transmitted in the FCH symbols, which includes a cyclic prefix field to identify the cyclic prefix length used in the data payload. A receiver may know the cyclic prefix length used in the FCH symbols in one embodiment. In other embodiments, the receiver does not know the FCH cyclic prefix length and, therefore, attempts to decode the FCH symbols using different possible cyclic prefix lengths until the FCH symbols are successfully decoded.
