1. A method comprising:receiving, by a first base station:
first configuration information indicating a starting symbol parameter that is indicative of a start, in at least one subframe, of a first physical downlink control channel associated with the first base station; and
second configuration information indicating that the first physical downlink control channel is to be transmitted by the first base station in fewer than all resource blocks of the at least one subframe;
receiving, by a second base station, the first configuration information; and
transmitting, by the second base station, a second physical downlink control channel using second radio resources that are configured, based on the first configuration information, to manage overlap with first radio resources of the first physical downlink control channel.
