Enhanced control channel for a wireless device
First Claim
Patent Images
1. A method for use in a wireless device, the method comprising:
- a) transmitting a first radio resource control (RRC) message comprising a parameter indicating whether said wireless device supports an enhanced physical downlink control channel (ePDCCH);
b) receiving, if said parameter indicates support of said ePDCCH, a second RRC message causing configuration of;
i) first radio resources of a first ePDCCH comprising one or more sets of resource blocks in a subset of subframes in a plurality of subframes, said second RRC message indicating;
(1) a starting OFDM symbol of said first ePDCCH in said subset of subframes; and
(2) 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 to start from said starting OFDM symbol in said subset of subframes; and
c) receiving on said first ePDCCH scheduling information for a packet transmitted on said first data channel.

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. The base station transmits scheduling information on the first ePDCCH.

8. 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 comprising a parameter indicating whether said wireless device supports an enhanced physical downlink control channel (ePDCCH); ii) receive, if said parameter indicates support of said ePDCCH, a second RRC message causing configuration of; (1) first radio resources of a first ePDCCH comprising one or more sets of resource blocks in a subset of subframes in a plurality of subframes, said second RRC message indicating; (a) a starting OFDM symbol of said first ePDCCH in said subset of subframes; and (b) 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 to start from said starting OFDM symbol in said subset of subframes; and iii) receive on said first ePDCCH scheduling information for a packet transmitted on said first data channel. - View Dependent Claims (9, 10, 11, 12, 13)

14. A base station comprising:
-
a) one or more communication interfaces; b) one or more processors; and c) memory storing instructions that, when executed, cause said base station to; i) receive a first radio resource control (RRC) message comprising a parameter indicating whether a wireless device supports an enhanced physical downlink control channel (ePDCCH); ii) transmit, if said parameter indicates support of said ePDCCH, a second RRC message causing, in said wireless device, configuration of; (1) first radio resources of a first ePDCCH comprising one or more sets of resource blocks in a subset of subframes in a plurality of subframes, said second RRC message indicating; (a) a starting OFDM symbol of said first ePDCCH in said subset of subframes; and (b) 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 to start from said starting OFDM symbol in said subset of subframes; and iii) transmit on said first ePDCCH scheduling information for a packet transmitted on said first data channel. - View Dependent Claims (15, 16, 17, 18, 19, 20)
