Channel interleaving structure for a wireless communication system

Abstract

Systems and methodologies are described that facilitate employing a hybrid transmission structure in a wireless communication environment. Each transport block (e.g., MAC PDU) can be split into multiple code blocks. Moreover, each of the code blocks can be further divided into two or more code block segments. Further, code block segments from a given code block can be transmitted over a channel during disparate time slots of a subframe. Also, within a given subframe, code block segments corresponding to differing code blocks can be transmitted sequentially in time. Utilization of the foregoing can enable employment of a pipelined decoder structure at a receiver while allowing for optimization of time / frequency diversity.

A typical wireless communication system or network may support multiple users accessing one or more shared resources (eg, bandwidth, transmit po...

AI Technical Summary

Problems solved by technology

However, the time diversity of some traditional transmission structures is poor, especially when the channel conditions change rapidly (for example, fast fading channels due to the high-speed movement of wireless communication devices, ...), the problem is particularly prominent

In addition, some other commonly used transmission structures have poor frequency diversity

Also, some typical transmission structures cause decoder-related delays (e.g., decoding of multiple code blocks starts after the subframe in which reception of these multiple code blocks is completed simultaneously)
