As a TP detects a random access signal on a random access resource, it (and/or other entities in the wireless network) can deduce that the random access resource belonged to the set of allowed random access resources selected by the device, in various embodiments. In various embodiments, depending on the random access mappings, a TP (and the wireless network) can also make further deductions, for example about the measurement results, service requirements or other aspects taken into account in the random access mapping. In one embodiment, a TP (and the wireless network) can deduce that a measurement result for the measurement RS transmitted by the TP is the highest among the measurement results for the measurement RSs using the same sync reference.
In other words, a TP (and the wireless network) obtains certain knowledge immediately after a random access signal detection. In various state of the art and other wireless systems, this knowledge may not be available immediately after a random access signal detection, but is available much later, typically after first responding that the random access signal was successfully received and subsequently receiving further information from the device.
