Abstract: The present invention is concerned with different novel concepts for reducing latency in data transmission. These concepts may be exploited by a transceiver configured to perform wireless data communication with a third party device by aggregating time division duplex carriers having different temporal distribution of uplink times and downlink times. These concepts may further be exploited by an apparatus configured to perform data transmission or reception via allocations of transmission resources of aggregated carriers in units of transmission time intervals into which the aggregated carriers are subdivided, wherein the aggregated carriers are temporally subdivided into the transmission time intervals in a temporal grid, respectively, wherein the aggregated carriers' grids are temporally mutually offset.

Abstract: The transmission of data signals transmitted by a plurality of transmitters may be rendered more efficient by combining multi-user superposition coding with appropriate phase shift estimation at the receiver so that phase shift compensation at the transmitter's side may lead to a superposition of the data signals which may be demapped correctly so as to obtain information data per data signal. Owing to the combination, the concept is applicable to typical uplink situations or downlink situations of separate contributing BSs: contrary to the simple downlink situation where the data signals stem from one BS and are superimposed in one domain, namely the base station's domain, the data signals to be superimposed stem from separate transmitters, such as user entities or mobile terminals in the typical uplink situation, or different base stations in the downlink situation.
