Abstract
Based on measurement reports reported to a base station by a plurality of UEs, the base station or a data system may dynamically configure a location of a physical random access control channel (PRACH) defined by the base station such that the PRACH is located in an optimal location. In one example, a data system may receive a plurality of subband CQI reports that includes one or more subband CQI values reported to the base station by each of a plurality of UEs served by the base station. The data system may determine, based on the plurality of subband CQI reports, that a particular range of resource blocks has a highest reported downlink air interface quality. And the data system may cause the base station define a PRACH instance in the particular range of resource blocks for carrying random access requests from the plurality of UEs to the base station.
