Carry out the scheme that the present invention will be described in detail embodiment provides with reference to the sending method shown in table 1 and Fig. 2 a and 2b.
The first situation, when the detection interval of second communication node is the detection interval shown in table 1, if DCI1 The detection interval that is formed for { 1~search space of search space 4 } shown in table 1 of detection interval in, then the detection interval of DCI2 Also in the detection interval formed for { 1~search space of search space 4 } shown in table 1.
The second situation, when the detection interval of second communication node is the detection interval shown in table 1, if DCI1 The detection interval that is formed for { 1~search space of search space 4 } shown in table 1 of detection interval in, then the detection interval of DCI2 The time-frequency code resource occupied for the search space in DCI1 is { ECCn~ECCEn+15 } as shown in Table 1, but the polymerization of DCI2 Degree can be different with DCI1, for example the degree of polymerization of DCI2 is { 4,8 }, or the degree of polymerization of DCI2 is { 1,2,5 }.
The third situation, when the detection interval of second communication node is the detection interval shown in table 1, if DCI1 The detection interval that is formed for { 1~search space of search space 4 } shown in table 1 of detection interval in, then the detection interval of DCI2 The proper subclass for the time-frequency code resource { ECCn~ECCEn+15 } as shown in Table 1 occupied for the search space in DCI1, preferably In the detection interval of DCI2 search space where DCI1.If terminal (the second communication node) detects DCI1 in search space 2, then the detection space of DCI2 only include search space 2.
Further, the candidate outside candidate control channel shared by DCI1 is removed in search space where DCI2 occupies DCI1 Control channel, such as DCI1 occupy the candidate control channel 1 in search space 2, then the detection space of DCI2 is by search space 2 Remaining candidate control channel 2~6 form, or at this time DCI2 detection space be search space 2 in remaining candidate control The running time-frequency resource that channel 2~6 occupies is formed, but the degree of polymerization of DCI2 can not be 2.
4th kind of situation, when the detection interval of second communication node is the detection interval shown in table 1, if DCI1 The detection interval that is formed for { 1~search space of search space 4 } shown in table 1 of detection interval in, then the detection interval of DCI2 The proper subclass for the time-frequency code resource { ECCn~ECCEn+15 } as shown in Table 1 occupied for the search space in DCI1, further Ground, the search space where DCI2 are determined according to the corresponding channel coding rates of DCI1.
Wherein, the channel coding rate of DCI2 is more than or equal to the corresponding channel coding rates of DCI1, according to DCI2's Channel coding rate determines the degree of polymerization where DCI2, and then determines search space, for example detects the channel coding speed of DCI2 Rate is r1, and channel coding rate r21, r22, r23, the r24 of 1,2,4,8 corresponding DCI2 of the degree of polymerization, wherein r21, r22 are both greater than R1, then the detection space of DCI2 be made of the corresponding search space of the degree of polymerization { 4,8 }.This, which allows for DCI1 and DCI2, to have There is similar code rate.
From the above description, it will be seen that DCI1 and DCI2 share detection interval, or (the two-stage control of shared search space Channel processed is located in identical search space), while reducing terminal detection control channel complexity, realize dynamic transfer mode Switching, efficiently uses control channel resource, this is because：Terminal first detects it signal in space and carries out equalizing demodulation, this Signal after a little equalizing demodulations can be used for decoding DCI1 and DCI2, so that new equalizing demodulation will not be carried out for DCI2.
