Subject: IEEE 802.16 Ad-hoc for LE Co-existence
Importance: High


Dear Colleagues,

At the closing Plenary of IEEE 802.16 Session #30, we have
 decided to set up an Ad-Hoc correspondence group for
 study of co-existence in below 11GHz LE (License Exempt)
 bands and make a recommendation to the WG, at May 802.16
 meeting.

I would propose, as charter for this group:

1. Identification of scenarios in which interference between cells
 can cause disruption in service; will be taken into account both
 "access providers" installations and private networks;

2. Identification of techniques which may mitigate the problem,
 such as dynamic frequency selection, time co-ordination,
 creation of interference free periods, etc;

3. Identification of minimum set of interoperability requirements that
 will reduce the service disruption problems.

I would propose to adopt as parameters for this study, to be agreed
 by the Ah-hoc group:

- Operating frequency: 5.8GHz, under FCC UNII rules;
- System architecture: P-MP;
- BST antennae: omni, sectorial;
- SS antennae: omni, directional;
- Behaviour under interference: according to radio parameters specified
 in 802.16-REVd.

- Co-ordination assumptions:
        - none
            - frame duration and start time synch
        - Rx/Tx duty cycle alignment
        - air protocol
        -etc.

In order to kick-off this activity, please let me know if you wish
 to participate. I will create a special e-mail list.

Regards,

Marianna
