Abstract

A base station transmits on a first control channel first scheduling information for a control message. The base station transmits the control message configuring second radio resources of a second control channel. The second radio resources comprise resource blocks in a subset of subframes. The control message indicates the subset of subframes and a starting symbol of the second control channel and a data channel. The base station transmits second scheduling information on the second control channel.
