Title:
TECHNIQUES FOR UPLINK CONTROL INFORMATION (UCI) BASED UPLINK PREEMPTION INDICATION TRANSMISSIONS
Document Type and Number:
WIPO Patent Application WO/2021/036961
Kind Code:
A1
Abstract:
Aspects described herein relate to uplink control information (UCI) based uplink preemption indication. In one example, a first node such as an integrated access and backhaul (IAB) node may determine that data having a priority level is to be transmitted on an uplink communication channel to a second node. The first node transmits UCI including a preemption indication representing a punctured uplink transmission of the data to the second node after transmission of the data. In another example, a first node such as a parent node in an IAB system may receive, from an IAB node, UCI including a preemption indication representing a punctured uplink reception of the data. In both examples, the UCI may be associated with a preemption indication cycle representing a number of time or frequency resources.
