A method and apparatus for transmitting a downlink channel measurement reference signal and a method and apparatus for receiving the downlink channel measurement reference signal are provided in the present invention. The transmission method comprises the following steps: a network side determines other Orthogonal Frequency Division Multiplexing (OFDM) symbols except the OFDM symbols used for transmitting control signal, the OFDM symbols used for transmitting the Cell specific Reference Signal (CRS) and the OFDM symbols used for transmitting the Demodulation Reference Signal (DM-RS), and transmitting the downlink channel measurement reference signal (CSI-RS) on the determined other OFDM symbols. The specific solution that a transmitter transmits the downlink channel measurement reference signal and a UE receives the CSI-RS signal is provided by the present invention, and transmitter could transmit and receive the CSI-RS signal according to the solution provided by the present invention.

A method, a device and a system for indicating terminal specific Demodulation Reference Signal (DMRS) are provided by the invention. The method includes that: a network side creates signal indicating information, and sends the created signal indicating information to a terminal (S501); the terminal, according to Transmission Block (TB) indicating information of the TB and multiple bits control information which are included in the signal indicating information, confirms DMRS pattern information, antenna port information and a scrambling ID of a reference signal sequence (S502) allocated for itself. The method, the device and the system provide by the invention, compared to the prior art, reduce signaling overhead which indicates the terminal specific DMRS, thus reducing resources waste of the system.

A method, system and device for wireless communication are provided by the present invention. The method includes that: from the ending of the Transmit-Receive Guard interval (TRG) to the beginning of the Receive-Transmit Guard interval (RTG), an evolved Node B (eNB) carries Common Reference Signals (CRSs) or Demodulated Reference Signals (DMRSs) on the carriers are used for transmitting data signals and/or control signals to a Relay Node (RN); the RN demodulates, according to the CRSs or the DMRSs, the signals transmitted by the eNB; the TRG is the guard interval of the transition, for the RN, from transmitting signals to receiving signals over the backhaul link, and the RTG is the guard interval of the transition, for the RN, from receiving signals to transmitting signals over the backhaul link. The application of the present invention enables the RN to receive the data signals and/or control signals transmitted by the eNB correctly.

摘要:
The present invention relates to a touch positioning method and system as well as a display device. Said touch positioning method is applied to an optical touch screen comprising a touch detection area, two imaging devices, a light source and a reflector, the touch detection area and its mirror image touch detection area with regards to the reflector residing within field of view of each imaging device, the method comprising: obtaining location information of touch objects based on image data of an actual touch object and its mirror image touch object with regards to said reflector acquired by said two imaging devices, said touch objects comprise said actual touch object and virtual touch object; obtaining location information of said actual touch object from the location information of said touch objects based on the mirror image relation between said actual touch object and its mirror image touch object as well as the location information of said touch detection area. The present invention may avoid the presence of “ghost images” during the positioning of more than two touch objects and accurately locate where the touch objects reside.
