Data transmission in a wireless communication system with reduced latency

A wireless communication system, comprising a receiver, wherein the receiver, includes:

• one or more antennas for receiving a data signal;
• and
• a signal processor for processing the data signal,
• wherein the data signal comprises at least one data signal block, the data signal block having a number of symbols in the time domain and a number of sub-carriers in the frequency domain,
• wherein the data signal block comprises a control region to provide control data to the receiver and a payload region to provide payload data to the receiver,
• wherein payload data is allocated to the control region of the data signal block,
• wherein the control data is provided in a control message,
• wherein the payload data is not part of the control message but is located at different parts of the control region,
• wherein the control data includes first data indicating the one or more parts of the control region to which the payload data is allocated, and second data indicating how the payload data at the different parts of the control region is to be processed, the second data including information about the modulation and additional information for processing the user payload data provided at the different parts of the control region, and
• wherein the additional information includes one or more of the following:
• precoding information, a downlink assignment index, DAI, an uplink transmission power indication comprising a TPC command, a transport block to codeword swap flag,
• wherein the control region of the data signal block includes information indicating a receiver to which the payload data is directed, and
• wherein the information indicating the receiver to which the payload data is directed is separate from the control data.

A method, comprising:

• receiving and processing, by a receiver a data signal, the data signal comprising at least one data signal block, the data signal block having a number of symbols in the time domain and a number of sub-carriers in the frequency domain,
• wherein the data signal block comprises a control region to provide control data to the receiver and a payload region to provide payload data to the receiver, and
• wherein payload data is allocated to the control region of the data signal block,
• wherein the control data is provided in a control message,
• wherein the payload data is not part of the control message but is located at different parts of the control region,
• wherein the control data includes first data indicating the one or more parts of the control region to which the payload data is allocated, and second data indicating how the payload data at the different parts of the control region is to be processed, the second data including information about the modulation and additional information for processing the user payload data provided at the different parts of the control region, and
• wherein the additional information includes one or more of the following:
• precoding information, a downlink assignment index, DAI, an uplink transmission power indication comprising a TPC command, a transport block to codeword swap flag,
• wherein the control region of the data signal block includes information indicating a receiver to which the payload data is directed, and
• wherein the information indicating the receiver to which the payload data is directed is separate from the control data.
