US 2026/0032678 A1 · DATA TRANSMISSION METHOD AND APPARATUS

Abstract

This application provides a data transmission method. In an example of the method, a terminal device receives scheduling information from a network device, where the scheduling information is used to schedule the terminal device to perform data transmission on a first transmission resource, a frequency domain resource of the first transmission resource is located on an uplink subband of an activated bandwidth part BWP of the terminal device, and the BWP further includes a downlink subband neighbor to the uplink subband. The terminal device performs data transmission on the first transmission resource based on a first transmitter requirement.
