[------Start of Text Proposal------]
6.12.2.2.2.2.x Forwarding of MAC messages to and from the HR-BS
A forwarding HR-MS shall forward power and measurement control and related messages from the HR-BS to the forwarded HR-MS and measurement results from the forwarded HR-MS to the HR-BS.
6.12.2.2.2.2.yMeasurements used for HR-MS power control
The HR-BS may request HR-MS that have a direct link to other HR-MS to perform the following measurements and report their results. In addition the HR-BS may define conditions for event based reporting. The allowed conditions for event based reporting are the same as for the corresponding measurements performed on HR-BS signals.
Average CINR_C mean is the average CINR of an HR-MS with which the reporting HR-MS has a direct communication link;
RSSI_C mean is the received signal strength from the HR-MS
BLER_C is the average BLER of a channel received from the HR-MS.
These measurements are requested and reported according to AAI.
6.2.3.65.xx AAI-HR-PCC
The AAI-HR-PCC message shall be used by an HR-MS receiving transmission from another in order to control its power.
Message AAI-HR-PCC
Field / Size [bits] / Value / description / ConditionsIoT_C / 7 / IoT value for control channels, quantized in 0.5 dB steps as IoT level from 0 dB to 63.5 dB
Offset_C / 6 / Offset value for control channels, represents the value among -15.5 to 16 dB with 0.5 dB step
IoT_D / 7 / IoT value for data channels, quantized in 0.5 dB steps as IoT level from 0 dB to 63.5 dB
Offset_D / 6 / Offset value for data channels, represents the value among -15.5 to 16 dB with 0.5 dB step
