1. A method comprising:
monitoring a physical downlink control channel of a cell for downlink control information; and
in response to detecting the downlink control information, determining whether a field of the downlink control information indicates that a reduced capability user equipment is supported in the cell,
in response to the field of the downlink control information not indicating reduced capability support:
determining whether the field of the downlink control information comprises cell reselection assistance information;
in response to determining that the field of the downlink control information comprises cell reselection assistance information, performing a search using the cell reselection assistance information to locate a reduced capability supported cell; and
in response to determining that the field of the downlink control information does not comprise cell reselection assistance information, performing a search without using assistance information to locate a reduced capability supported cell.
