摘要： A wireless communication system includes a first wireless communication node for transmitting a data signal that is sent to a second wireless communication node by skywave propagation over at least two different data transmission paths. The first data transmission path includes at least one reflection point where the data signal is reflected by the atmosphere and the second data transmission path includes more reflection points than the first data transmission path. The data signal that travelled along the first data transmission path is decoded before the data signal that travelled along the second data transmission path.

摘要： A method of receiving a reference signal by a user equipment. A first channel state information-reference signal (CSI-RS) configuration related to a discovery of a transmission point is received. A second CSI-RS configuration related to a CSI measurement is received. A CSI-RS according to the first CSI-RS configuration or the second CSI-RS configuration is received. Feedback information is transmitted to a base station. If the CSI-RS has been received according to the first CSI-RS configuration, the feedback information includes information on a CSI-RS received strength. If the CSI-RS has been received according to the second CSI-RS configuration, the feedback information includes a result of the CSI measurement.

摘要： A method of wirelessly communicating a screen image between a mobile device and a base station coupled to a display terminal includes receiving, at the mobile device, electromagnetic (“EM”) radiation emitted from a base station and incident upon an antenna of the mobile device. A screen image generated by the mobile device is encoded onto a backscatter channel of the EM radiation by modulating an impedance of the antenna. The screen image is transmitted from the mobile device to the base station for display on a display terminal coupled to the base station.

摘要： A communication system uses multiple communications links, preferably links that use different communications media. The multiple communications links may include a high latency/high bandwidth link using a fiber-optic cable configured to carry large volumes of data but having a high latency. The communications links may also include a low latency/low bandwidth link implemented using skywave propagation of radio waves and configured to carry smaller volumes of data with a lower latency across a substantial portion of the earth's surface. The two communications links may be used together to coordinate various activities such as the buying and selling of financial instruments.

摘要： The invention discloses a random access method and apparatus so as to perform random access for a User Equipment (UE) with a plurality of aggregated cells in a carrier aggregation-enabled LTE-A system. The method includes: determining a secondary cell configured for a UE and obtaining random access related parameter preset for the secondary cell; and sending the random access related parameter to the UE to instruct the UE to initiate random access procedure over the secondary cell corresponding to the random access related parameter. The inventive method achieves the purpose of enabling the UE to be synchronized with the network side by performing random access over a specified cell, having the UE maintain uplink synchronization with the network side in the configured secondary cell and ensuring the overall performance of the system.
