stds-80220-requirements: Antenna Diversity Requirement, 4.1.13


yuza@NEC-i

I fully agree with Mr Shigeru Kimura's comment on August 8th,
with same rationale.

It is enough to require of antenna diversity in section 4.1.13
Support for Multi Antenna Capabilities.


Section 4.1.13 - Antenna Diversity(Rev.7)

  Proposed New text
  N/A(Delete section)


Shigeru's comment--------

  Section 4.1.12 - Antenna Diversity

  Current text

  At a minimum, both the Base Station and the Mobile Terminal shall
  provide two element diversity. Diversity may be an integral part of
  an advanced antenna solution.
  Proposed New text
  N/A(Delete section)

  Rationale

  Support for multiple antenna capability is described section 4.1.11.
  Section 4.1.12 defines a minimum antenna number for
  Base Station and Mobile Terminal.
  There is a contradiction between 4.1.11 and 4.1.12.
  Only  section  4.1.11  description is enough for multiple antenna
capability I
  think.
  And the antenna number of Mobile Terminal should not be defined in the
  Requirements Document.
  The important thing is the system performance with cost.

Dear ALL

  This is Shigeru Kimura.


  I want to propose to remove the section 4.1.12 of Rev 5.





  Section 4.1.12 - Antenna Diversity


  Current text

  At a minimum, both the Base Station and the Mobile Terminal shall
  provide two element diversity. Diversity may be an integral part of
  an advanced antenna solution.
  Proposed New text
  N/A(Delete section)


  Rationale

  Support for multiple antenna capability is described section 4.1.11.
  Section 4.1.12 defines a minimum antenna number for
  Base Station and Mobile Terminal.
  There is a contradiction between 4.1.11 and 4.1.12.
  Only  section  4.1.11  description is enough for multiple antenna
capability I
  think.
  And the antenna number of Mobile Terminal should not be defined in the
  Requirements Document.
  The important thing is the system performance with cost.

  Thank you.
