Data Transmission Method and Apparatus

A data transmission method, wherein the method comprises:

• sending first configuration information to a second node, wherein the first configuration information indicates at least one of time domain resource or frequency domain resource of a first time-frequency resource;
• sending second configuration information to the second node, wherein the second configuration information is used to indicate whether segmentation of a data packet on a first logical channel is allowed, the first logical channel corresponds to a second time-frequency resource, and the second time-frequency resource is comprised in the first time-frequency resource;
• and
• receiving first data from the second node by using the first time-frequency resource.

A data transmission apparatus, comprising:

• one or more processors, and
• a non-transitory storage medium in communication with the one or more processors, wherein the non-transitory storage medium stores program instructions that, when executed by the one or more processors, cause the apparatus to:
• receive first configuration information from a first node, wherein the first configuration information indicates at least one of time domain resource or frequency domain resource of a first time-frequency resource;
• obtain first information corresponding to a first logical channel, wherein the first information is used to indicate whether segmentation of a data packet on the first logical channel is allowed, the first logical channel corresponds to a second time-frequency resource, and the second time-frequency resource is comprised in the first time-frequency resource;
• and
• send first data to the first node by using the first time-frequency resource.

• a non-transitory storage medium in communication with the one or more processors, wherein the non-transitory storage medium stores program instructions that, when executed by the one or more processors, cause the apparatus to:
• send first configuration information to a second node, wherein the configuration information is used to configure a first time-frequency resource;
• send second configuration information to the second node, wherein the second configuration information is used to indicate whether segmentation of a data packet on a first logical channel is allowed, the first logical channel corresponds to a second time-frequency resource, and the second time-frequency resource is comprised in the first time-frequency resource;
• and
