METHODS AND APPARATUS OF TWO STAGE DOWNLINK CONTROL INFORMATION - A simplified explanation of the abstract

This abstract first appeared for US patent application 18331290 titled 'METHODS AND APPARATUS OF TWO STAGE DOWNLINK CONTROL INFORMATION

Simplified Explanation

The patent application describes methods and devices for transmitting and receiving downlink control information (DCI) in a wireless network. Here is a simplified explanation of the abstract:

  • The invention introduces a two-stage process for transmitting DCI in a wireless network.
  • In the first stage, a DCI is transmitted that explicitly indicates the scheduling information of a second stage DCI.
  • The second stage DCI is then transmitted in a physical downlink shared channel (PDSCH) according to the scheduling information.
  • The first PDSCH is a physical channel that does not transmit any data.
  • The receiving apparatus does not need to perform blind decoding of the second stage DCI because it already knows its location from the scheduling information.

Bullet points:

  • Two-stage process for transmitting downlink control information (DCI) in a wireless network.
  • First stage DCI explicitly indicates the scheduling information of a second stage DCI.
  • Second stage DCI is transmitted in a physical downlink shared channel (PDSCH).
  • The first PDSCH is a physical channel without data transmission.
  • Receiving apparatus does not need to perform blind decoding of the second stage DCI.
  • Location of the second stage DCI is known from the scheduling information.


Original Abstract Submitted

Methods for transmitting and receiving downlink control information (DCI) are provided along with corresponding network devices and apparatus. A first stage DCI is transmitted that explicitly indicates a scheduling information of a second stage DCI. The second stage DCI is transmitted in a first physical downlink shared channel (PDSCH), consistent with the scheduling information. The first PDSCH is a physical channel without data transmission. The receiving apparatus does not need to perform blind decoding of the second stage DCI because it is aware of its location from the scheduling information.
