Data Transmission Method and Apparatus

A data transmission method, comprising:

• sending first configuration information to a second node, wherein the first configuration information indicates at least one of a first time-domain resource or a first frequency-domain resource, wherein at least one of the first time-domain resource or the first frequency-domain resource carries first data and a first reference signal, and wherein the first reference signal is a demodulation reference signal of the first data;
• and
• receiving the first reference signal on a second time-frequency resource,
• wherein the second time-frequency resource does not overlap a third time-frequency resource, and
• wherein the third time-frequency resource is for carrying atleast one of second data or a control-type signal.

An apparatus, comprising:

• a non-transitory storage medium configured to store program instructions
• a processor coupled to the non-transitory storage medium and configured to execute the program instructions that cause the apparatus to:
• receive first configuration information from a first node, the first configuration information indicates at least one of a first time-domain resource or a first frequency-domain resource, wherein at least one of the first time-domain resource or the first frequency-domain resource is for carrying first data and a first reference signal, and wherein the first reference signal is a demodulation reference signal of the first data;
• and
• transmit the first reference signal on a second time-frequency resource,
• wherein the second time-frequency resource does not overlap a third time-frequency resource, and
• wherein the third time-frequency resource is for carrying at least one of second data or a control-type signal.
