METHOD AND APPARATUS FOR USING DIFFERENT TIMING ADVANCES BASED ON DIFFERING RESOURCE TYPES
One method includes a node first receiving a first information block used for determining a first timing advance value; and then sending a target signal, wherein when the time domain resource occupied by the target signal belongs to a first time domain resource set, the first timing advance value is used for the sending timing of the target signal; and when the time domain resource for the target signal does not belong to the first time domain resource set, the first timing advance value is not used for the sending timing of the target signal. Embodiments improve the timing advance determination mode in a sub-band full multiplexing scenario, thereby improving the overall performance and flexibility of a system.
