Title:
METHOD AND APPARATUS FOR SETTING SLOT FORMAT FOR IAB NODE
Document Type and Number:
WIPO Patent Application WO/2020/262982
Kind Code:
A1
Abstract:
In the present specification, settings for a link direction and link availability of a time resource for a DU child link may be referred to as DU setting. The resource types from an IAB node DU perspective are UL, DL, and F, and the settings for availability may be classified into NA, hard resources, and soft resources, respectively. Specifically, the IAB node may receive resource setting information, wherein the resource setting information may include link direction information and availability information. The link direction information may indicate whether the type of a specific resource is UL, DL, or F, and the availability information may indicate whether a specific resource is a hard resource, an NA resource, or a soft resource. Considering the feature of sharing resources in a TDM scheme between a MT and a DU in the IAB node, the present specification proposes a feature to be had by a slot format setting for the IAB node.
