[STDS-802-16] [MMR-AH-UM] The separation of control and data in relaying



All,

 

Do we want to talk about the separation of control and data in relaying? That is, the control information (preamble, MAP, and etc.) from BS is directly transmitted to MS without relay involved. And data is relayed for throughput enhancement. This is dedicated for throughput enhancement relay, where MS is located within the coverage of BS to get the BS broadcast information directly. This broadcast information is always transmitted with the most robust modulation scheme (which has the highest possible reach).

 

The separation of control and data may provide some advantages:

1, Simple RS design: all the control and scheduling functions are located in BS, and RS only takes responsibility of data forwarding under BS coordination.

2, Bandwidth saving: RS does not need to forward these broadcast information

3, No delay for MAP information: if RS is required for relaying MAP or other control messages to MS, some extra delay is inevitable.

4, easy handover within one BS coverage.

 

Best Regards,

 

Gang Shen

All,

Do we want to talk about the Relay separation/isolation between Rx to Tx: in Frequency, Time, Space (antenna directivity or physical separation) or any mixed between them? The type of isolation will enforce the relay coverage gain (or interference), delay, cost etc. this will lead to the best fit for each coverage area type, this will lead to the question if we want one size (solution) that feet all? If we want to keep this question open then we have to reflect that in the document.

Jerry and all,

 

My comments are:

 

a) Uniformity of titles in 3.1-3.4

I do not feel uniformity of title in section 3.

So my suggestion is

 3.1 Outdoor coverage ....

 3.2 In-building coverage ....

 3.3 Temporally coverage ...

 3.4 Mobile platform coverage ....

 

Can we say RS characteristics in this section

since they are missing in the crrent version?

 

b) 4. Performance objective

Is it possible to describe in general way

why performance enhancement is expected ?

For example,

 - Link is divided into shorter ranges by RSs to increase received signal strength

 - RSs are located selecting better condition of field strength for both receiving and transmitting

 - RS decodes information and re-transmits it with certain delay and frequency scheduling

    to obtain better performance. Interference mitigation is expected.

 - etc.

 

Best Regards,

Asa

Dear Ad Hoc participants,

 

As we discussed in the previous meeting the next meeting of the Multihop Relay Usage Model Ad Hoc Group will occur on Thursday June 1,  06:00 – 08:00 PDT (13:00 – 15:00 UTC). (At the meeting we will discuss varying the meeting times to accommodate people’s schedules).

 

The bridge for the meeting is 916-356-2663, Bridge: 1, Passcode: 8272405.

 

I have updated the draft to include modifications to the outline that we agreed to in the May 25 meeting and to incorporate some preliminary text into the sections (based on content from session 43 contributions). I encourage participants to review the draft and to discuss the draft via email before the meeting. I will send out an agenda for the meeting on Wednesday. The new draft is in the temp directory in the upload server in the following location: C80216j-06_UMAHtemp_r1.doc .

 

I look forward to a productive discussion and to making progress toward our goal of creating a harmonized contribution.

 

Best Regards,

Jerry Sydir
