1. A method comprising:
- a) receiving, by a base station, a first radio resource control (RRC) message from a wireless device on a primary carrier in a plurality of carriers, said first RRC message comprising one or more parameters indicating whether said wireless device supports an enhanced physical downlink control channel (ePDCCH);
b) transmitting, by said base station, selectively and if said one or more parameters indicates support of said ePDCCH, at least one second RRC message configured to cause, in said wireless device, configuration of;
i) first radio resources of a first ePDCCH of a first carrier, said first radio resources comprising one or more sets of resource blocks in a subset of subframes in a plurality of subframes, said at least one second RRC message indicating;
(1) a starting OFDM symbol of said first ePDCCH in said subset of subframes;
(2) a frequency allocation for said first ePDCCH in terms of resource blocks in said subset of subframes; and
(3) a configuration of said subset of subframes in which said first radio resources of said first ePDCCH are configured; and
ii) second radio resources of a first data channel of said first carrier to start from said starting OFDM symbol in said subset of subframes;
c) transmitting first transmission format and scheduling information by said base station on said first ePDCCH in a first subframe of said subset of subframes, said first transmission format and said scheduling information being for one or more first data packets transmitted on said first data channel of said first carrier; and
d) transmitting said one or more first data packets by said base station to said wireless device on said first data channel in said first subframe according to said first transmission format and said scheduling information.

Abstract
A base station receives a first radio resource control (RRC) message comprising parameter(s) indicating whether a wireless device supports an enhanced physical downlink control channel (ePDCCH). The base station transmits a second RRC message causing configuration of first radio resources of a first ePDCCH and second radio resources of a first data channel. The second RRC message indicates a frequency allocation for the first ePDCCH in terms of resource blocks in a subset of subframes. The base station transmits scheduling information on the first ePDCCH in a first subframe.

9. A wireless device comprising:
-
a) one or more communication interfaces; b) one or more processors; and c) memory storing instructions that, when executed, cause said wireless device to; i) transmit a first radio resource control (RRC) message to a base station, said first RRC message comprising one or more parameters indicating whether said wireless device supports an enhanced physical downlink control channel (ePDCCH); ii) receive at least one second RRC message causing, in said wireless device, configuration of; (1) first radio resources of a first ePDCCH of a first carrier, said first radio resources comprising one or more sets of resource blocks in a subset of subframes in a plurality of subframes, said at least one second RRC message indicating; (a) a starting OFDM symbol of said first ePDCCH in said subset of subframes; (b) a frequency allocation for said first ePDCCH in terms of resource blocks in said subset of subframes; and (c) a configuration of said subset of subframes in which said first radio resources of said first ePDCCH are configured; and (2) second radio resources of a first data channel of said first carrier to start from said starting OFDM symbol in said subset of subframes; iii) receive first transmission format and scheduling information from said base station on said first ePDCCH in a first subframe of said subset of subframes, said first transmission format and said scheduling information being for one or more first data packets transmitted on said first data channel of said first carrier; and iv) receive said one or more first data packets from said base station on said first data channel in said first subframe employing said first transmission format and said scheduling information. - View Dependent Claims (10, 11, 12, 13)
