Abstract
A transmission timing determining method and apparatus are provided, to determine a transmission timing of an IAB node. The method is applied to a first node, and a second node may be an upper-level node or a donor node of the first node. The method includes: The first node receives control information from the second node, where the control information includes scheduling information of uplink transmission, and the control information includes first scrambling information. The first node determines a first timing type associated with the first scrambling information. The first node determines a transmission timing of the uplink transmission based on the first timing type.
Claims17
A transmission timing determining method, comprising:
- receiving, by a first node, configuration information from a second node, wherein the configuration information comprises an association relationship between a time unit index and a timing type;
- determining, by the first node based on the association relationship, a first timing type associated with a first time unit;
- and
- determining, by the first node based on the first timing type, a transmission timing for performing uplink transmission in the first time unit,
- wherein the time unit index is an index determined at a reference subcarrier spacing;
- and
- the determining, by the first node based on the association relationship, a first timing type associated with a first time unit comprises:
- determining, by the first node, the first timing type associated with the first time unit based on the reference subcarrier spacing, a subcarrier spacing corresponding to the first time unit, and the association relationship.
An apparatus, comprising:
- a transceiver;
- a processor;
- and
- a non-transitory computer-readable storage medium storing a program to be executed by the processor, the program comprising instructions to:
- receive configuration information from a second node, wherein the configuration information comprises an association relationship between a time unit index and a timing type;
- and
- determine, based on the association relationship, a first timing type associated with a first time unit, and determine, based on the first timing type, a transmission timing for performing uplink transmission in the first time unit,
- wherein the time unit index is an index determined at a reference subcarrier spacing;
- and
- the program including instructions to:
- determine the first timing type associated with the first time unit based on the reference subcarrier spacing, a subcarrier spacing corresponding to the first time unit, and the association relationship.
A non-transitory computer readable storage medium, storing computer instructions that, when executed by an apparatus, cause the apparatus to perform:
- receiving configuration information, wherein the configuration information comprises an association relationship between a time unit index and a timing type;
- determining based on the association relationship, a first timing type associated with a first time unit;
- and
- determining based on the first timing type, a transmission timing for performing uplink transmission in the first time unit,
- wherein the time unit index is an index determined at a reference subcarrier spacing, and
- the determining, by the first node based on the association relationship, a first timing type associated with a first time unit comprises:
- determining, by the first node, the first timing type associated with the first time unit based on the reference subcarrier spacing, a subcarrier spacing corresponding to the first time unit, and the association relationship.
