Abstract
Official abstract text for this publication.
A method and apparatus for indicating slot format information is disclosed. The method comprising: t receiving a RRC (radio resource control) signaling indicating a time domain starting position of a slot format information and determining the time domain starting position based on the RRC signaling.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of an integrated access and backhaul (IAB) node for indicating slot format information, the method comprising: receiving the slot format information indicating time domain resources of a slot format used for: downlink reception on a first link between the IAB node and a parent node of the IAB node; uplink transmission on the first link between the IAB node and the parent node; flexible communication on the first link between the IAB node and the parent node; and downlink or uplink communication on a second link between the IAB node and a child node of the IAB node or a third link between the IAB node and a serving user equipment (UE) of the IAB node; determining whether the downlink or uplink communication of the indicated time domain resources are for the second link between the IAB node and the child node, or the third link between the IAB node and the UE; and determining whether each time domain resource of the indicated time domain resources is for downlink communication, or uplink communication. 2. The method of claim 1 , wherein the slot format information comprises at least one format for one or more symbols of one or more slots. 3. The method of claim 2 , wherein a symbol group size is indicated by a radio network temporary identifier of downlink control information. 4. The method of claim 2 , wherein a symbol group size is indicated by a starting position of a payload of a cell in downlink control information. 5. The method of claim 2 , wherein a symbol group size is indicated by a symbol when downlink control information is detected. 6. The method of claim 2 , further comprising reserving rows in a table used for each group size, and different rows in the table are associated with different group sizes. 7. A integrated access and backhaul (IAB) node for indicating slot format information, the IAB node comprising: at least one memory; and at least one processor coupled with the at least one memory and configured to cause the IAB node to: receive the slot format information indicating time domain resources of a slot format used for: downlink reception on a first link between the IAB node and a parent node of the IAB node; uplink transmission on the first link between the IAB node and the parent node; flexible communication on the first link between the IAB node and the parent node; and downlink or uplink communication on a second link between the IAB node and a child node of the IAB node or a third link between the IAB node and a user equipment (UE) of the IAB node; determine whether the downlink or uplink communication of the indicated time domain resources are for the second link between the IAB node and the child node, or the third link between the IAB node and the UE; and determine whether each time domain resource of the indicated time domain resources is for downlink communication, or uplink communication. 8. The IAB node of claim 7 , wherein the slot format information comprises at least one format for one or more symbols of one or more slots. 9. The IAB node of claim 8 , wherein a symbol group size is indicated by a radio network temporary identifier of downlink control information. 10. The IAB node of claim 8 , wherein a symbol group size is indicated by a starting position of a payload of a cell in downlink control information.
