Note: UML part has been executed. TR document paragraph is still to be written.
Adding a new symbolRateReductionFactor:Integer attribute to the TypeDefinitions::TransmissionModeType data type to express the reduced symbol rate applied e.g. with ¼ BPSK (symbolRateReductionFactor = 4) and ½ BPSK (symbolRateReductionFactor = 2).
Defining the default value of TypeDefinitions::TransmissionModeType::symbolRateReductionFactor == 1.
Adding the following comment to the symbolRateReductionFactor: "Reduction factor for the symbol rate. Example: value would be 4 for 1/4BPSK."
Adding a new transmissionModeName:String attribute to the TypeDefinitions::TransmissionModeType data type to allow naming of the transmission mode by the vendor.
Adding AirInterface::AirInterfaceConfiguration::_transmissionModeMin and AirInterface::AirInterfaceConfiguration::_transmissionModeMax attributes according to issue#15 for configuring the symbolRateReductionFactor.
Adding an AirInterface::AirInterfaceStatus::_transmissionModeCur attribute according to issue#14 for expressing the operational status of the symbolRateReductionFactor.
Defining the TypeDefinitions::timeXStatesType data type and adding the TypeDefinitions::AirInterfacePerformanceType::timeXStatesList attribute according to issue#15 for expressing the performance values.
Adding a paragraph to TR-532 that explains the behavior in regards to characteristics (e.g. channel bandwidth) that are not recorded as a performance value by the device.
The current ONF TR-532 1.0 model doesn’t foresee on AirInterfacePerformanceType the dedicated attributes for ¼ BPSK and ½ BPSK modulation value as for the other modulations (like time2States and so on), to report the time the radio interface (MW-AirInterface_Pac instance) stays on ¼ BPSK or on ½ BPSK modulation values.
The request is to manage also these Counters.
Mainly, the idea is to replace with a list the whole set of counters of the number of seconds the device operated a specific transmission-mode .
A list entry is composed by a key and a counter (as in the figure 1). The key references a valid transmission mode.
In the list are created only the entries related to the transmission-mode whose channel-bandwidth matches the one set in air-configuration.
The following figure shows the transition from the air-interface performance defined by the current model to the proposed structure.
