Description
Technical field
The present invention relates to the communications field, in particular to a kind of control channel self adaptation launching technique and device.
Background technology
LTE (Long-Term Evolution, Long Term Evolution)/LTE-Advanced system and IMT-Advanced (International Mobile Telecommunications, international mobile communication) system all is with OFDM (Orthogonal Frequency DivisionMultiplexing, OFDM) technology is the basis, in ofdm system, it is the data mode of time-frequency bidimensional, for UE (User Equipment, subscriber equipment) end power saving, control channel adopts TDM (Time Division Multiplex usually, time division multiplexing) mode, that is, control channel and Traffic Channel are separated in time, for example, 14 OFDM symbols are arranged in a subframe, and preceding 3 OFDM symbols are as control channel, and back 11 OFDM symbols are as Traffic Channel.
In existing system, the user who often allow to insert is more, and at first the control channel with present LTE system is that example describes.In the LTE system, descending control signaling mainly comprises following content:
1) CCFI (Control Channel Format Indicator, the indication of control channel form);
2) DL Grant (Down Link Grant, descending scheduling mandate);
3) UL Grant (Up Link Grant, uplink scheduling authorization);
4) HI:HARQ indication (Hybrid Automatic Repeat Request Indication mixes automatic repeat requests indication);
As can be seen, the design of control channel is to be made of different parts, and each part all has its specific function.For convenience of description, define several terms and agreement below:
1) CCFI promptly indicates several OFDM symbols to be used for control channel, and is independent with CCE (ControlChannels Elements, control channel unit); HI is also independent with CCE;
2) be called CCE at the continuous L of a frequency domain subcarrier, CCE can comprise DL Grant and UL Grant;
3) all CCE are the QPSK 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 has been stipulated several combinations, for example has only 1,2,4,8 CCE to combine as the candidate control channel;
9) the corresponding different coding speed of 1,2,4,8 combination difference;
Fig. 1 is the schematic diagram according to the transmitter architecture of correlation technique, as shown in Figure 1, hold at Node-B (enode), each UE (UE1 to UEn) control signaling is carried out chnnel coding respectively, carry out the QPSK modulation then, carry out CCE to RE (ResourseElement, subcarrier) forms E-CCFI, carry out the subcarrier mapping then, space diversity, carry out IFFT (Inverse Fast Fourier Transform, inverse-Fourier transform) adds CP, parallel/serial DAC, and launch, suppose that this moment, control channel was made of 16 CCE, receiving terminal carries out FFT (Fast Fourier Transform, Fourier transform) after, UE begins to carry out blind Detecting (promptly respectively to CCE1 from being combined as 1 CCE, CCE2, ..., CCE16 carries out blind Detecting), if UE_ID does not monitor success, then carry out blind Detecting (promptly respectively to [CCE1 CCE2] from being combined as 2 CCE, [CCE3 CCE4], ..., [CCE15CCE16]), 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.Because it is travel through all CCE combined situation, too much for the blind Detecting number of times of some UE as can be seen.
In LTE/LTE-Advanced and IMT-Advanced system, support QPSK, 16QAM, 64QAM modulation system, and much all be identical in the modulation system of a plurality of UE of synchronization, if all launch this information in the control signaling of each UE, so just increased the expense of control signaling.But can be placed on E-CCFI (Enhanced-Control Channel Format Indicator to what have an identical modulation system, strengthen the indication of control channel form) lining, content in the E-CCFI comprises the maximum sequence number of the CCE of professional modulation system and correspondence, transmitting terminal only is mapped in the UE that each has the identical services modulation system in the corresponding CCE serial number range deserved CCE, can reduce the blind Detecting time like this; And the CCE of the identical more UE of modulation system this moment is placed on front or centre or back, can further reduces the blind Detecting time of most of UE like this.E-CCFI promptly reduces the control signaling consumption, and can reduce number of times, reduction UE end handling process and the power loss of UE end blind Detecting to a certain extent.
Fig. 2 is that as shown in Figure 2, the control information form of expanding among the E-CCFI is made of two parts according to the schematic diagram of the E-CCFI composition of correlation technique, professional maximum sequence number of CCE and the indication of professional modulation system of adopting different modulation systems respectively, wherein,
CCFI: the number that is used to indicate the shared OFDM symbol of control channel;
N1: the maximum sequence number of CCE under following/up M1 modulation system;
M1: the modulation system of following/Traffic Channel that up frequency of utilization is the highest;
N2: the maximum sequence number of CCE under following/up M2 modulation system;
M2: down/modulation system of the Traffic Channel that up frequency of utilization is time high;
N3: the maximum sequence number of CCE under following/up the 3rd kind of modulation system;
N4: on/descending m1 modulation system under the maximum sequence number of CCE;
M1: on/modulation system of the Traffic Channel that descending frequency of utilization is the highest;
N5: on/descending m2 modulation system under the maximum sequence number of CCE;
M2: on/modulation system of the Traffic Channel that descending frequency of utilization is time high;
N6: on/descending the 3rd kind of modulation system under the maximum sequence number of CCE.
In realizing process of the present invention, the inventor finds that there are the following problems at least in the prior art: at present, the signaling consumption of research control to(for) content, the method for salary distribution, the minimizing of control signaling is a focus, but, do not consider effective control channel self adaptation emission, for example, CCFI is all the time in emission in the original system, or the E-CCFI control information is all the time in emission in the improved system, but, launch the self adaptation emission of CCFI structure and E-CCFI structure in other words at the control information self adaptation of expanding among the E-CCFI and do not carry out discussing and research.
