Re: [802.3_EPOC] Meeting Notes from Today's EPOC Topics Meeting



Joe, sorry I couldn't the call due to a conflict (weekly).  I would like to make a suggestion to build consensus on the following "consensus challenge items". 

 

There are dependencies among the items and they are of different nature - some items are features (capabilities required by the MSOs to offer a specific service), some are necessary standard changes required to support certain features, and some are performance.

 

For example, below are some of the dependencies:

3)/7)/10)/13) (OFDMA for upstream) è 6/8/14/15

With such dependencies, we should understand what features are in scope for EPOC TF - in particular, 3), 7), 10), 17. Before these are settled, other items such as 6, 9, 11, 12, 14, 15, 16, will be just moving targets.

 

My 2c.

 

Best, Rick

 

1)      RF Bandwidth - haven't yet pinned down the width

2)      FDD Downstream - OFDM initially

3)      Bonding approach for DS: Should it happen higher in another device, Mac, or PHY?

4)      Rate adaptation: what layer of PHY should it occur in?

5)      FEC: Need channel model for progress

6)      MPCP changes: to what extent does it need to be extended

7)      Adaptive bit rate loading

8)      PHY link (discovery and startup)

9)      Complexity of HW scaling with bandwidth: 

10)   TDD

11)   Coding efficiency: gain vs. cost

12)   Synch in terms of time/frequency

13)   OFDM Numerology/FFT size/symbol size/CP size

14)   Framing structure

15)   MAC layer efficiency

16)   PHY efficiency

17)   Energy efficiency

Team,

 

Please find attached my notes from today's EPOC Topics meeting. 

 

On the call it was agreed that this meeting remains a good forum for discussion of EPOC topics; we will continue meeting on a weekly basis.
