Title:
METHOD AND APPARATUS FOR SUPPORTING POWER SHARING AND CONTROL BETWEEN IAB LINKS IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/060232
Kind Code:
A1
Abstract:
A method and apparatus for supporting power sharing and/or control between integrated access and backhaul (IAB) links in a wireless communication system is provided. When a first node (e.g., IAB node) performs a downlink (DL) transmission to a wireless device (e.g., user equipment (UE)) based on a DL resource and an uplink (UL) transmission to a second node (e.g., another IAB node and/or donor node) based on a UL resource at a same time interval, the DL resource and the UL resource are separated by at least one guard physical resource block (PRB) in a frequency domain.
