    摘要: A relay node, time division duplex communication system and communication method are disclosed. The communication system comprises a base station, mobile stations and the relay node. The relay node will not be in receiving and transmitting state synchronously. The communication method comprises that the relay node receives a first signal from the base station in a predetermined downlink subframe of a frame and transmits a second signal to the base station in a predetermined uplink subframe of the frame, wherein the first signal is a response signal for the second signal or the second signal is a response signal for the first signal

    摘要: In one embodiment, a method of streaming media includes partitioning a media stream to be transmitted into a first stream of media segments at a media server. The first stream of the media segments has a first sequence. An index table is generated to identify the first sequence of the first stream of the media segments. The index table is encrypted using a key. A second stream of the media segments is generated. The second stream has a second sequence, which is random relative to the first sequence. The encrypted index table and a transcoded media stream having the second stream of the media segments are transmitted.

    摘要: Oxazolidinium compounds are formed by the reaction of a halohydrin or an epoxide with a secondary amine and an aldehyde or a ketone. The oxazolidinium compounds are formed directly and do not require the reaction of a pre-formed oxazolidine with an alkylating agent. The compounds are useful as gas hydrate inhibitors in oil and gas production and transportation.
