Data and control multiplexing for uplink data transmission method and device

An uplink data transmission device comprising:

• a processor;
• a receiver;
• and
• wherein the receiver is configured to cooperate with the processor to:
• receive a control symbol sent by a terminal device using a control time-frequency resource,
• wherein the control symbol is generated from control information according to encoding and modulation schemes at the terminal device,
• wherein the control information indicates data encoding and modulation schemes at the terminal device,
• wherein the control information is an index value associated with the data encoding and modulation schemes,
• wherein the control information is determined according to a one-to-one mapping relationship between parameter sets and index values,
• wherein each parameter set comprises an encoding scheme and a modulation scheme, and
• wherein any two parameter sets are different in at least one of the encoding scheme and the modulation scheme,
• wherein the control time-frequency resource belongs to a transmission resource for uplink transmission,
• wherein the transmission resource further comprises a data time-frequency resource, and
• wherein the control time-frequency resource and the data time-frequency resource are different;
• the processor is configured to:
• demodulate and decode the control symbol according to the encoding and modulation schemes at the terminal device to obtain the control information;
• and
• decode, according to the control information, a data symbol to obtain uplink data,
• wherein the data symbol is received from the terminal device through the data time-frequency resource.
