Data transmission method, network device, and terminal

A terminal, comprising:

• a processor, configured to obtain a time-frequency resource used to transmit uplink data, wherein the time-frequency resource is at least one time-frequency resource block selected from a plurality of time-frequency resource blocks, each of the plurality of time-frequency resource blocks is corresponding to one piece of configuration information, and the configuration information comprises at least identification information of the corresponding time-frequency resource block used to transmit uplink data, and
• select the at least one time-frequency resource block from the plurality of time-frequency resource blocks based on a previous corresponding statistical success rate of transmission;
• and
• a transceiver, configured to transmit the uplink data on the at least one selected time-frequency resource block based on configuration information of the at least one time-frequency resource block selected by the processor, wherein the identification information is a start position or an index number of the corresponding time-frequency resource block or the identification information corresponds to one or more groups of terminals or one or more sub-bands, wherein each of the plurality of time-frequency resource blocks occupies a same bandwidth, or at least two of the plurality of time-frequency resource blocks occupy different bandwidths.

A chip, comprising at least one processor and an interface, wherein

• the processor is configured to obtain a time-frequency resource used to transmit uplink data, wherein the time-frequency resource comprises a plurality of time-frequency resource blocks, the information about the time-frequency resource comprises configuration information corresponding to each time-frequency resource block, and the configuration information comprises at least identification information of the corresponding time-frequency resource block used to transmit uplink data;
• and
• the processor is further configured to:
• when the uplink data needs to be sent, select at least one time-frequency resource block from the plurality of time-frequency resource blocks based on a previous corresponding statistical success rate of transmission, and provide the at least one selected time-frequency resource block for a transceiver through the interface, wherein the identification information is a start position or an index number of the corresponding time-frequency resource block or the identification information corresponds to one or more groups of terminals or one or more sub-bands, wherein each of the plurality of time-frequency resource blocks occupies a same bandwidth, or at least two of the plurality of time-frequency resource blocks occupy different bandwidths.
