AI Technical Summary

Technical Problem

Existing 5G mobile communication systems still lack sufficient methods to improve communication efficiency in the uplink, especially in the processing of multi-slot transport blocks, where there is a trade-off between processing latency and decoding performance.

Method used

In multi-timeslot transmission, the control circuit determines the reading position of the encoded data of the signal by using a rate matching method with variable redundancy version positions based on the reading position of the encoded data in multiple intervals within the time domain resources of the signal transmission, thereby improving communication efficiency.

Benefits of technology

It effectively reduces terminal processing latency, improves uplink communication efficiency, reduces the risk of degradation in decoding performance, and simplifies the complexity of conflict handling.

Abstract

A communication device includes: control circuitry that decides, based on an amount of resources that does not depend on a reading result of coded data in a second interval that is earlier than a first interval among a plurality of intervals within a time-domain resource allocated to a signal transmission, a reading position of the coded data of the signal in the first interval; and transmission circuitry that transmits the signal based on the reading position.
