Description
Technical field
The present invention relates to a kind of frequency multiplexing technique, especially a kind of sending, receiving method of up-link information and transmission, receiving terminal.
Background technology
In orthogonal frequency division multiplex OFDM (Orthogonal Frequency Division Multiplexing) system, OFDM is by being decomposed into data flow the experimental process data flow, each sub data flow has lower bit rate like this, and each sub data flow is modulated to the transmission that walks abreast on the corresponding subcarrier respectively then.It is pointed out that be not only between each subcarrier of OFDM mutually orthogonal, and have 1/2 overlapping.
In the LTE system, take into full account peak-to-average force ratio PAPR (the Peak Average Power Ratio) problem of user terminal UE (User Equipment), that is to say that the instantaneous value of the output signal of transmitter has bigger fluctuation.This will require more intrasystem parts, and for example power amplifier, A/D, D/A converter etc. have very big linear dynamic range.And conversely, the non-linear of these parts also can produce nonlinear distortion to the bigger signal of dynamic range, and the harmonic wave that is produced can cause the phase mutual interference of subchannel, thereby influences the performance of ofdm system.
Uplink multi-address has finally been selected the multiplexing multiple access SC-FDMA of single carrier frequency division (Single Carrier-Frequency Division Multiple Access) in the LTE system, and very important reasons is the PAPR problem.Because the information symbol of single-carrier system is (or some the simple distortion) that directly is modulated on the time domain, so its PAPR is lower, review multicarrier system, owing to have a plurality of carrier waves to transmit information symbol simultaneously at one time, and the information symbol of each carriers carry is separate, so PAPR is bigger, generally than the big 2-3dB of single-carrier system.High PAPR has increased the requirement to the power amplifier linearity, and this point is especially unfavorable to UE, so more satisfactory scheme of uplink multi-address is the single-carrier system of band Cyclic Prefix, i.e. SC-FDMA.
LTE system, LTE-A system, IMT-Advanced system all are based on OFDM (OrthogonalFrequency Division Multiplexing) technology, it in ofdm system the data mode of time-frequency bidimensional, for the power saving of UE end, control channel adopts TDM (Time DivisionMultiplex) mode usually, that is to say that control channel and Traffic Channel separate in time, 14 OFDM symbols are for example arranged in a subframe, preceding 3 OFDM symbols are as control channel, and back 11 OFDM symbols are as Traffic Channel.
At first the control channel with present LTE system is that example describes.For example in the LTE system, Downlink Control Information mainly comprises following content:
1) CCFI (control channel format indicator): control channel form indication;
2) DL grant (downlink grant): descending scheduling authorization message;
3) UL grant (Uplink Grant): uplink scheduling authorization information;
4) HI (HARQ Indicator): HARQ (Hybrid Automatic Repeat Request) indication;
The design of control channel is to be made of different parts as can be seen, and each part all has its specific function.For convenience of description, define several terms and agreement below,
1) indicating several OFDM symbols to be used for control channel is CCFI, independent with CCE; HI is also independent with CCE;
2) be called CCE (Control channels elements) control channel unit at the continuous L of a frequency domain subcarrier, CCE can comprise DL grant and UL grant;
3) all CCE are QPSK (Quadrature Phase Shift Keying) modulation;
4) each control channel is by a CCE or CCE constitutes;
5) each UE can monitor a series of candidate control channels;
6) number of candidate control channel is the maximum times of blind Detecting;
7) number of candidate control channel is greater than the number of CCE;
8) transmitting-receiving two-end provides several combinations, for example has only 1,2,4,8 CCE to combine the control channel as the candidate;
9) the corresponding different coding speed of 1,2,4,8 combination difference;
In Node-B (Node B, also be the base station) end, chnnel coding is carried out in the control information of each UE respectively, carry out the QPSK modulation then, carry out the mapping of CCE to RE, carry out going out after the IFFT conversion emission, suppose that this moment, control channel was made of 32 CCE, after receiving terminal carries out the FFT conversion, UE begins to carry out blind Detecting (promptly respectively to CCE0 from being combined as 1 CCE, CCE1, ..., CCE31 carries out blind Detecting), if UE_ID does not monitor success, then carry out blind Detecting (promptly respectively to [CCE0CCE1] from being combined as 2 CCE, [CCE2CCE3], ..., [CCE30CCE31]), and the like.If all do not listen to the UE_ID that is complementary with oneself in whole blind detection process, illustrating does not have one's own control signaling to assign this moment, and then UE switches to sleep pattern; If listen to the UE_ID that is complementary with oneself, afterwards according to the corresponding business information of control signal demodulation.
At present, for the multi-access mode research based on ofdm system is a focus, but the Notification Method research for multiple multi-access mode is less, with the LTE system is example (having only a kind of multi-access mode in the system at present), the LTE system descending adopts orthogonal frequency division multiplexing multiple access OFDMA (Orthogonal Frequency Division Multiple Access) at present, the multiplexing multiple access SC-FDMA of up employing single carrier frequency division, but can not be applicable to well that (LTE-Advanced system and IMT-Advanced system have proposed to use the demand of multiple multi-access mode to multiple access in new system, uplink multi-address mode as the candidate can be the multiplexing multiple access SC-FDMA of single carrier frequency division, orthogonal frequency division multiplexing multiple access OFDMA, the multiplexing multiple access clustered of the single carrier frequency division of sub-clustering SC-FDMA, N the multiplexing multiple access N of single carrier frequency division x SC-FDMA arranged side by side etc.), how transmitting-receiving two-end knows this moment or next which kind of multi-access mode that adopts constantly so, and this is this invention problem that will solve just.
