      proposal 1:
      - for 1/2 lamda spaced antennas, several seperated wider beam can formed, thus it enables:
      1. CQI and codebook vector is less varying (hundreds of ms);
      2. multiple beams with 1 beam per SS. (for thinner beam, it is unlikely to find 4 SSs);
      4. multiplexing number < Nt. When a beam in fixed beam grid is selected, the neighbour beams nearby in two sides will be set to null for inter-beam interference avoidance.
      5. the point 4 above will lead to dynamic interference problem;

      - Why???: common pilots approach significantly saves radio resources

      proposal 2:
      multiplexing by both spatial beamforming and polarization:
      - such as two closely spaced cross-polarized antenna pairs

      persistent scheduling support for VoIP upto 200 simuteneous users (25 ms per frame):
      persistent allocation IE in MAP (normal/compressed/sub-MAP, DL/UL).
      however, there will be loss on multi-user diversity.

      Personally I prefer Moto's proposal which piggyback the persistent allocation/de-allocation info in DSA/DSD. Since it use unicast and per burst AMC, it enjoys higher SE.

      Samsung's Pattern is the worst. Since they put the pilots too close, the t-f position far from pilots has too week correlation with pilots and so is worse performance. Pilot should be placed uniformly.

      If I brought AP, why should I pay for the Wireless Access Provider?
      If I have paid for the access, why should I investigate on infrastracture myself, but not by wireless operator?

      I won't buy femtocell unless operator pay me!!!

  • require smaller cells and lower power to reduce interference and increase the total data throughput not per cell but per square mile
  • Which makes one wonder: Why is a data-centric company like Google even interested?
  • simply bidding to make sure some of its open access requirements are imposed on an eventual winner, which will only happen under FCC rules if the bidding for that C Block goes to at least $4.6 billion
  • trade that block to Sprint/Nextel for some of that company’s 2.5-GHz WiMAX licenses
  • The thought of unused or underused spectrum got the juices flowing at companies including Intel, Microsoft and Philips, who banded together to propose that they be allowed to offer unlicensed data service in so-called “white space” within and between existing broadcast frequencies—piggybacking, as it were, on the bandwidth allocated to TV broadcasters and wireless providers.
