Abstract
Provided are a timing determination method and device, a communication node and a storage medium. The timing determination method includes: determining a timing parameter; and determining transmission timing of a target node according to the timing parameter, where the transmission timing includes at least one of a time difference between first timing and second timing, downlink transmit timing (DTT) or uplink transmit timing (UTT).
Claims19
A timing determination method, comprising:
- determining a timing parameter;

- determining transmission timing of a target node according to the timing parameter, wherein the transmission timing comprises at least one of:
- a time difference between first timing and second timing, downlink transmit timing (DTT) or uplink transmit timing (UTT);
- wherein the time difference between first timing and second timing refers to a time difference between the DTT of a serving cell and downlink receive timing (DRT) of an integrated access and backhaul (IAB) node, the DTT refers to DTT of the IAB node, and the UTT refers to UTT of the IAB node;
- wherein the transmission timing comprises a timing argument;
- wherein the timing argument is determined according to at least one of the following manners:
- Tdelta=(Ndelta+Tdelta·Gstep)·Tc;
- Tdelta=(−NTA,offset/2+Ndelta+Tdelta·Gstep)·Tc;
- or
- Tdelta=(NTA,offset/2+Ndelta+Tdelta·Gstep)·Tc;
- wherein Tdelta denotes the timing argument, NTA denotes a timing advance adjustment number or a timing lag adjustment number, NTA,offset denotes a timing advance offset or a timing lag offset, Tc denotes a time unit, Tdelta denotes a timing argument index value, Ndelta denotes a timing argument offset, and Gstep denotes a timing argument granularity.
A communication node, comprising a memory, a processor and a computer program stored in the memory and executable by the processor, wherein the processor, when executing the computer program, implements a timing determination method, wherein the timing determination method comprises:

- and
- determining transmission timing of a target node according to the timing parameter, wherein the transmission timing comprises at least one of:
- a time difference between first timing and second timing, downlink transmit timing (DTT) or uplink transmit timing (UTT);
- wherein the time difference between first timing and second timing refers to a time difference between the DTT of a serving cell and downlink receive timing (DRT) of an integrated access and backhaul (IAB) node, the DTT refers to DTT of the IAB node, and the UTT refers to UTT of the IAB node;
- wherein the transmission timing comprises a timing argument;
- wherein the timing argument is determined according to at least one of the following manners:
- Tdelta=(Ndelta+Tdelta·Gstep)·Tc;
