SLOT POSITION OFFSETS ASSOCIATED WITH A DOWNLINK CONTROL INFORMATION IN A PHYSICAL DOWNLINK SHARED CHANNEL - A simplified explanation of the abstract
- This abstract for appeared for patent application number 18335871 Titled 'SLOT POSITION OFFSETS ASSOCIATED WITH A DOWNLINK CONTROL INFORMATION IN A PHYSICAL DOWNLINK SHARED CHANNEL'
Simplified Explanation
The abstract describes a method used by a base station (BS) to transmit control information to a user equipment (UE). The control information is divided into two parts: the Physical Downlink Control Channel (PDCCH) and the Physical Downlink Shared Channel (PDSCH). The PDCCH includes a first part of the control information (DCI), while the PDSCH includes a second part of the DCI (referred to as a 2-part DCI).
In this method, the first grant associated with the second part of the DCI is offset from the slot position of the second part. Additionally, a second grant associated with the second part of the DCI is offset from the slot position to which the first grant is offset. This offsetting allows for efficient transmission of the control information.
Another aspect of this method involves grouping two or more grants together, and then mapping the respective group to a Physical Uplink Control Channel (PUCCH). This grouping and mapping further enhances the transmission efficiency of the control information.
Original Abstract Submitted
In an aspect, a PDCCH and a PDSCH are transmitted by a BS to a UE, whereby the PDCCH includes a first DCI part and the PDSCH includes a second DCI part (e.g., a 2-part DCI). In an example a first grant associated with the second DCI part is offset relative to a slot position of the second DCI part, whereas a second grant associated with the second DCI part is offset relative to the slot position to which the first grant is offset. In another aspect, two or more grants are grouped together, with the respective group being mapped to a PUCCH.
