Decision

Analysis resulted in changing into unidirectional objects would (if possible) not be backward compatible.

Unidirectional objects will not to be part of TR-532 v1.1

Issue#25 remains open

Background

When radio is equipped with single transmitter and 2 receivers

  • two possible solutions presented in the proposals

  • decision to stick with the 'solution 2' with 2 airInterface and to work to a 'clean' solution to introduce unidirectional objects; this would cover the case of space diversity and future scenarios of P2MP

  • the  proposal would be that the new solution would be added to the current one (possibly marked as 'deprecated')
  • in order to start this analysys it is needed to go through the model and identify the parameters that are applicable to TX and RX


A table comparing the TX and RX classes have been discussed:

Proposals for sorting airInterface attributes into TX and RX classes

    In the WT call of 18/4 it has been decided to have a modified proposal from Thorsten to address the cases of bidirectional parameters; deadline moved to 25/4

  2. Giorgio Cazzaniga

    In the WT call of 2/5 it has been verified that there are still pending the actions; deadline moved to 25/5 after modelling session in Italy

    What about the proposal to have additional attributes ?

    • for capability class, to report if the second receiver on the air-interface is supported (receiverDivIsAvailable ? ) ,
    • for configuration class, to enable (combinerControl?)  the feature and to activate/deactivate (receiverDivIsOn ?) the second receiver )
    • for status class, to report the current signal received on the Diversity receiver (rxDixLevelCur?)
    • for performanceType class , to report the value of Performance Dara referring to Diversity receiver (rxDixLevelMin, rxDixLevelMax, rxDixLevelAvg ?)
