In some embodiments, a measurement RS corresponds to a set of allowed random access resources. The device selects the union of the sets of allowed random access resources for the measurement RS's with measurement results within a certain range of the highest measurement result.
        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, the combined measurement result(s) that are within a certain range of the highest are used to select a set of allowed random access resources in such embodiments.
        In some embodiments, multiple measurement RS corresponds 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. In such embodiments, the device selects the union of the sets of allowed random access resources for the measurement RS's with measurement results within a certain range of the highest measurement result.
