  2. Resolution toComment #143 (CSMA/CA) & Comment #318(CAP) NICT

  3. Comment #143 • Subclause: 8.4.2(pp.43, l.46) • Comment: There are different factors that implies the CSMA/CA mechanism in the 60GHz band. The current definition does not address such important things like directed antennas, beamforming etc. It may happen that the CSMA/CA need changes to make it work in 60GHz band • SuggestedRemedy: Provide verified definition for CSMA/CA like mechanism for 60GHz band • Resolution: No change required. • Beamforming: According to the employed antenna directivities, CAP may be distributed into S-CAPs (CAPs for several directional antennas) each of which enables CSMA/CA mechanism in each direction • Interference mitigation: Co-channel interference due to antenna directionality may be mitigated by using peer discovery

  4. Comment #318 • Subclause: 8.16.2.3(pp.57, l.3) • Comment: CP is only limited to same mmWave PHY mode as the beacons with not limitation on rate and direction. • SuggestedRemedy: Mandate the use of common rate (quasi)-Omni only for CP accessing • Resolution: Reject comment. No need to limit common rate (quasi)-omni only for CP. CP is divided into S-CAP, where directional antenna is allowed, which enables to flexibly use all available transmissions.
