1. A method for use in a base station, the method comprising:
- a) transmitting on a first control channel, to a wireless device, first scheduling information for a control message, first radio resources of said first control channel in a subframe in a plurality of subframes starting from the first OFDM symbol of said subframe;
b) transmitting, to said wireless device, said control message comprising configuration parameters of second radio resources of a second control channel, said second radio resources comprising multiple sets of resource blocks in a subset of subframes in said plurality of subframes, said control message indicating;
i) said subset of subframes; and
ii) a first starting OFDM symbol of both said second control channel and a data channel in said subset of subframes; and
c) transmitting, to said wireless device, second scheduling information on said second control channel for a packet transmitted on said data channel; and
wherein said configuration parameters comprise an array of parameters, each element in said array comprising frequency resource parameters for a set of resource blocks in said multiple sets of resource blocks.

Abstract
A base station transmits on a first control channel first scheduling information for a control message. First radio resources of the first control channel start from the first symbol of each subframe in a plurality of subframes. 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 in the plurality of subframes. The control message indicates the subset of subframes and a starting symbol of the second control channel. The base station transmits second scheduling information on the second control channel.
