Multiple Timing Advance Groups for Integrated Access and Backhaul

Abstract: a method can include receiving, by an integrated access and backhaul (iab) node, a timing case indication medium access control (mac) control element (ce) for a first cell associated with at least two timing advance groups (tags). the timing case indication mac ce can indicate a transmission timing mode. the method can also include selecting a first tag from the at least two tags to apply the transmission timing mode. the method can further include transmitting an uplink signal using an uplink transmission time determined based on the transmission timing mode applied to the first tag.
