Support of time-frequency interleaving (for improved performance in time/frequency selective channels)

[jordijoangimenez]

Problem description

Time-frequency interleavers are a basic building block of most modern broadcast standards, and its inclusion in a system drastically improves performance in time and/or frequency selective channels.

The interleavers described in the 5G-MAG Report "Time and Frequency Interleaving for broadcast services in 3GPP Systems" have been designed with the objective of keeping maximum commonality with respect to current 3GPP specifications (e.g. by leveraging the HARQ operation to build a time interleaver) in order to ease implementation. The performance gains of these techniques have been captured for different scenarios alongside the drastic performance improvements of the 5G Broadcast system.

Suggested solution description

Incorporating time-frequency interleavers in future releases of 3GPP and ETSI 103 720.

If 3GPP approves a WI dealing with this, it can be referenced in the ETSI document (for information).
