DOWNLINK DATA RECEPTION OPERATION - A simplified explanation of the abstract

This abstract first appeared for US patent application 17754458 titled 'DOWNLINK DATA RECEPTION OPERATION

Simplified Explanation

Embodiments of the present disclosure relate to downlink data reception operation in a user equipment (UE) with a baseband processor.

• Receiving Downlink Control Information (DCI) through multiple beams from at least one TRP
• Determining a DCI transmission scheme (SFN, non-SFN, hybrid) based on upper layer signaling
• Checking if the received DCI indicates a Transmission Configuration Indicator (TCI) for PDSCH reception
• Selecting a TCI for PDSCH reception based on the determined DCI transmission scheme and candidate TCIs associated with Control Resource Sets (CORESETs)

• • Potential Applications:**

- 5G and future wireless communication systems - Mobile devices and networks - Internet of Things (IoT) devices

• • Problems Solved:**

- Efficient downlink data reception in a multi-beam communication environment - Optimizing PDSCH reception based on DCI transmission scheme and TCI indication

• • Benefits:**

- Improved data reception performance - Enhanced utilization of multiple beams for communication - Flexibility in selecting TCI for PDSCH reception based on DCI transmission scheme

Original Abstract Submitted

Embodiments of the present disclosure relate to downlink data reception operation. According to embodiments of the present disclosure, a baseband processor of a user equipment (UE) is configured to perform operations comprising receiving Downlink Control Information (DCI) through more than one beams from at least one from at least one TRP; determining a DCI transmission scheme for the received DCI, wherein the DCI transmission scheme is configured by an upper layer signaling, and wherein the DCI transmission scheme is one of a Single Frequency Network (SFN) scheme, a non-SFN scheme, and a hybrid scheme, wherein the DCI is transmitted using both SFN scheme and non-SFH scheme in the hybrid scheme; determining whether the received DCI indicates a Transmission Configuration Indicator (TCI) for PDSCH reception from the at least one TRP or not. The operations further comprise in accordance with a determination that the received DCI fails to indicate the TCI and based on the determined DCI transmission scheme, selecting at least one TCI for the PDSCH reception from candidate TCIs configured for one or more Control Resource Sets (CORESETs) associated with the DCI.
