Question: How does a UE derive the downlink pathloss reference RSRP for TA validation when nrofSS-BlocksToAverage or absThreshSS-BlocksConsolidation is not present?
Option 1: The UE derives the downlink pathloss reference RSRP as the linear average of all beam measurement quantity values.
Option 2: The UE derives the downlink pathloss reference RSRP as the highest beam measurement quantity value above a certain threshold.
Option 3: The UE derives the downlink pathloss reference RSRP as the highest beam measurement quantity value.
Option 4: The UE derives the downlink pathloss reference RSRP as the sum of all beam measurement quantity values.
Explanation: According to the specification, when nrofSS-BlocksToAverage or absThreshSS-BlocksConsolidation is not present, the UE shall derive the downlink pathloss reference RSRP for TA validation as the highest beam measurement quantity value. This ensures that the UE uses the strongest signal for pathloss reference derivation.
