  • This abstract for appeared for patent application number 18326121 Titled 'APPARATUS AND METHOD FOR COMMUNICATING TWO STAGE DCI'

Simplified Explanation

This abstract describes a method and apparatus for receiving downlink control information (DCI) in a wireless communication system. The method involves scrambling a first stage DCI using a radio network temporary identifier (RNTI) in a physical downlink control channel (PDCCH). The first stage DCI explicitly indicates the scheduling information of a second stage DCI. The second stage DCI is then sent in a first physical downlink shared channel (PDSCH), which is a physical channel without data transmission. The second stage DCI has a specific format, and the apparatus obtains this format based on the first stage DCI and the second DCI. This approach allows for flexibility in the formats of the second stage DCI.


Original Abstract Submitted

A method in an apparatus for receiving downlink control information (DCI) are provided. A first stage DCI is scrambled by a radio network temporary identifier (RNTI) in a physical downlink control channel (PDCCH), wherein the first stage DCI explicitly indicating a scheduling information of a second stage DCI. The second stage DCI is sent in a first physical downlink shared channel (PDSCH), the first PDSCH is a physical channel without data transmission. The second stage DCI has a second stage DCI format, and the apparatus obtains the at least one second stage DCI format based on at least one of the first stage DCI and the second DCI. This allows a lot of flexibility in formats of the second stage DCI.
