METHOD AND APPARATUS FOR MULTI-CELL SCHEDULING AND HARQ-ACK TRANSMISSION IN WIRELESS COMMUNICATION SYSTEM - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18305767 Titled 'METHOD AND APPARATUS FOR MULTI-CELL SCHEDULING AND HARQ-ACK TRANSMISSION IN WIRELESS COMMUNICATION SYSTEM'
Simplified Explanation
This abstract describes a method used by a user equipment (UE) in a communication system, specifically in a 5th generation (5G) or 6th generation (6G) system, to support higher data transmission rates. The method involves the UE receiving downlink control information (DCI) from a base station, which schedules a set of physical downlink shared channels (PDSCHs) across multiple cells. The UE then identifies the timing value for hybrid automatic repeat request-acknowledgement (HARQ-ACK) feedback based on the DCI. It also identifies a reference uplink slot based on the PDSCH that ends last among the set of PDSCHs in multiple cells. Using the HARQ-ACK feedback timing value and the reference uplink slot, the UE identifies an uplink slot for transmitting the HARQ-ACK information of the set of PDSCHs in multiple cells. Finally, the UE transmits a physical uplink control channel (PUCCH) containing the HARQ-ACK information to the base station in the identified uplink slot.
Original Abstract Submitted
The disclosure relates to a 5th generation (5G) or 6th generation (6G) communication system for supporting a higher data transmission rate. In accordance with an aspect of the disclosure, A method performed by a user equipment (UE) in a communication system is provided. The method includes receiving, from a base station, downlink control information (DCI) scheduling a set of physical downlink shared channels (PDSCHs) in multiple cells, identifying a hybrid automatic repeat request-acknowledgement (HARQ-ACK) feedback timing value based on the DCI, identifying a reference uplink slot based on a PDSCH ending last among the set of PDSCHs in multiple cells, identifying an uplink slot for HARQ-ACK information of the set of PDSCHs in multiple cells based on the HARQ-ACK feedback timing value and the reference uplink slot, and transmitting, to the base station, a physical uplink control channel (PUCCH) including the HARQ-ACK information in the uplink slot.
