Technical field

The present invention relates to the communications field, sending method and device in particular to a kind of instruction, The method of reseptance and device of instruction.

Background technology

In the wireless communication system of reality, because the radio propagation path between base station and terminal is easy Influenceed by environment, wireless channel has very big randomness.Therefore, in order to accurate in terminal The true signal for recovering base station and sending, it is necessary to which it is more accurate to be carried out to the channel information between base station and user Estimation, utilize estimation channel information calculate status information (Channel State Information, letter Referred to as CSI), and the CSI of calculating is fed back, base station carries out the scheduling of user according to the CSI of user feedback, And transmit data.Wherein, CSI includes：Channel quality indication (CQI) information (Channel quality indication, Referred to as CQI), precoding matrix indicators (Precoding Matrix Indicator, referred to as PMI) With order designator (Rank Indicator, referred to as RI).And still further aspect, with the channel of estimation The channel of the data area of transmission is estimated, is easy to be demodulated data and detect.

In Long Term Evolution (Long Term Evolution, LTE) version of early stage, such as (the letters of Release 8 Referred to as Rel-8) in version, terminal generally use public reference signal (Common Reference Signal, Referred to as CRS) CSI estimations are carried out, and terminal estimates DSCH Downlink Shared Channel also based on CRS The channel information of (Physical Downlink Shared Channel, PDSCH), and to transmission Data are demodulated.Strengthen (Long Term Evolution-Advanced, LTE A) in Long Term Evolution Rel-10 versions in, in order that terminal can carry out estimation and anti-to the antenna port of up to 8 The CSI of the bigger bandwidth of feedback, introduces new RS, i.e. channel state information reference signals (Channel State Information Reference Signal, CSI-RS), the CSI-RS newly introduced is sent out by base station Send, dedicated for carrying out the reference signal of channel measurement, the frequency pilot sign that terminal is sent based on base station CSI estimations are carried out, obtain letter of the different dual-mode antennas in the channel matrix H of different running time-frequency resource positions Breath, it can then be based on channel matrix H and carry out CSI quantizations and feedback.And introduce demodulation reference Signal (Demodulation Reference Signal, referred to as DMRS) is used to estimate descending share The channel of channel, and the data of transmission are demodulated.Both it is used for CSI with the CRS in earlier version Estimation is again different for signal demodulation, and DMRS and PDSCH has used identical precoding here, So as to which base station need not equally need to notify terminal to prelist used in it to the base station of Rel-8 versions again Code, on the one hand saves downlink signaling expense, also can preferably support the multiple-input and multiple-output of multi-user.
