AI Technical Summary

Technical Problem

In cellular communication systems, the transmission of PUSCH requested by PHICH may not be transmitted due to scheduling conflicts with PUSCH scheduled by the uplink grant, leading to inefficiencies in processing time and communication efficiency.

Method used

A terminal apparatus and base station apparatus are designed to manage HARQ processes in parallel, with the HARQ entity indicating non-adaptive retransmissions and setting ACKs in a state variable HARQ_FEEDBACK, allowing for efficient communication by adjusting transmission timing to avoid collisions and optimize processing time.

Benefits of technology

This solution enables efficient communication by ensuring that HARQ processes can manage collisions and adjust transmission timing, thereby improving the overall communication efficiency between the terminal apparatus and the base station apparatus.

Abstract

A terminal apparatus includes a medium access control layer processing unit configured to manage a HARQ process, and a physical layer processing unit configured to perform processing associated with a PUSCH transmission on a physical layer. A first HARQ process configured for the terminal apparatus determines whether or not to indicate to the physical layer processing unit to generate a transmission of the first HARQ process, based at least on whether or not the transmission of the first HARQ process and a transmission of a second HARQ process occur in the same transmission time. The transmission of the second HARQ process is scheduled so as to use short processing time.
