Abstract
Systems and methods for reducing signaling overhead between an Integrated Access and Backhaul (IAB) node and its parent node when switching between timing alignment cases are disclosed. In some embodiments, the method comprises sending one or more sets of desired numbers of guard symbols for two or more timing switching groups, respectively. The method further comprises receiving one or more sets of provided numbers of guard symbols for the two or more timing switching groups, respectively and determining available time resources for uplink transmission and/or downlink reception in two adjacent time units based on one of the one or more sets of provided numbers of guard symbols for one of the two or more timing switching groups that corresponds to timing alignment cases used in the two adjacent time units.
