1. A method for determining ePDCCH-based downlink control information at a user equipment, the method comprising:
receiving a control signaling from an eNB, wherein the control signaling comprises at least one ePDCCH set and corresponding configuration information thereof; determining candidate resource index information based on the control signaling based on a predetermined hash function
{(Yk+m)mod [NeREG,kn/LeREG]+Dm,L,K}+ieREG,L·[NeREG,kn/LeREG] where Yk=(A·Yk-1)mod D,
where NeREG,kn is the total configured eREG—enhanced-Resource Element Group—number of the specific UE,LeREG is the eREG number for each aggregation level L,Dm,L,K=m·{[NeCCE,kn/LeREG]/M(L)},ieREG,L=0, 1, . . . , LeREG−1 is the corresponding value for each aggregation level L depending on the eCCE—enhanced-Control Channel Element—definition,M(L) is the candidate number for each aggregation level L,Dm,L,K is the offset value to allocate all candidates evenly into all available eREGs, andan eCCE—enhanced-control Channel Element—location offset information SeCCEL=[NeCCE,K/M(L)]where SeCCEL is the location offset information for each aggregation level, NeCCE,K is the total number of eCCEs available, and M(L) is the candidate number for each Aggregation Level; performing DCI blind detection operation based on the candidate resource index information, so as to obtain downlink control information corresponding to the control signaling. |
