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.
Claims20
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.

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.
