1. A method for transmission on an unlicensed spectrum in a UE, comprising:Step A: receiving a higher layer signaling to obtain S and V, wherein the S is L configuration information, the V is N logical information, each of the configuration information comprises a carrier index and a working frequency band, and each of the logical information comprises at least one of the following:
a carrier logical index;
an antenna information, wherein the antenna information comprises a transmission mode; and
a cross carrier information, wherein the cross carrier information comprises a serving cell index;
Step B: receiving a first DCI, wherein the first DCI comprises a virtual index, a physical index and a scheduling information, and the scheduling information comprises a DMRS cyclic shift indication; and
Step C: transmitting a first uplink data from the working frequency band of a first configuration information in a given sub frame according to the scheduling information of the first DCI;
wherein, the first DCI complies with a configuration of a first logical information, the first logical information is that one logical information of the V with the carrier logical index being equal to the virtual index of the first DCI; all the working frequency bands of the S belong to the unlicensed spectrum, the L is a positive integer, the N is a positive integer not greater than L, and the first configuration information is that one configuration information of the S with the carrier index being equal to the physical index of the first DCI.
