Technique for providing a physical uplink shared channel bitstream

A technique for providing a Physical Uplink Shared Channel (PUSCH) bitstream is provided. A method implementation of this technique comprises the steps of obtaining encoded user data, interleaving the encoded user data, scrambling the interleaved encoded user data, and adding downlink feedback information to the scrambled encoded user data. The downlink feedback information may be at least one of information relating to a sub-frame reception status of the encoded user data and information relating to a number of transmission layers being able to be received under current channel conditions, in particular Rank Indication (RI) information.
