In some embodiments, a device obtains multiple different kinds of measurement results for a measurement RS, for example, RSRP and expected spectral efficiency. In some such embodiments, the multiple different kinds of measurement results may be combined into a combined measurement result. Then, which combined measurement result that is highest is used to select a set of allowed random access resources.
In some embodiments, multiple measurement RS's correspond to a set of allowed random access resources, where the multiple measurement RS's are used to obtain a measurement result. In some embodiments, different sets of multiple measurement RS's correspond to different sets of allowed random access resources. The set of allowed random access resources for the multiple measurement RS's with highest measurement result is selected, in various embodiments.
In some embodiments, a device obtains multiple different kinds of measurement results for multiple measurement RS (that correspond to a set of allowed random access resources), for example supported transmission rank and expected spectral efficiency on each supported layer. In some such embodiments, the multiple different kinds of measurement results may be combined into a combined measurement result. Then, the combined measurement result that is highest may be used to select a set of allowed random access resources.
In some embodiments, the measurement RS with highest measured RSRP is used to select a set of allowed random access resources.
In some embodiments, a set of allowed random access resources is selected only if the highest result is above a threshold.
