Patent ID: 8588195

Claim:
A data transmission method, comprising: determining, at the network side, a plurality of Modulation and Coding Schemes, MCSs, required for the same transport channel onto which a plurality of types of logical channels are mapped, and notifying a user equipment of a corresponding relationship between the logical channels and the MCSs; and modulating and encoding, at the network side, data of the logical channels mapped onto the transport channel according to the required MCSs, and transmitting the data to the user equipment over the transport channel, wherein notifying the user equipment of the corresponding relationship between the logical channels and the MCSs comprises: determining, at the network side, one or more types of specific logical channels among the plurality of types of logical channels mapped onto the same transport channel; transmitting, at the network side, a corresponding relationship between the specific logical channel(s) and an MCS(s) or an index(es) of the MCS(s) to the user equipment over a Broadcast Control channel, BCCH; and transmitting, at the network side, a corresponding relationship between the other logical channels mapped onto the same transport channel than the specific logical channel(s) and MCSs to the user equipment over the specific logical channel(s).
