Random Access Resource Information Based on Network Slices
A first base station having a first cell may receive, from a second base station having a second cell, one or more messages comprising first random access parameters for a first network slice of the second cell, second random access parameters for a second network slice of the second cell, and priority information indicating that the first network slice has a higher priority than the second network slice. After receiving the one or more messages, the first base station transmits, to one or more wireless devices, random access parameters of the first cell of the first base station.
