Method for Configuring Resource, Method for Receiving Downlink Control Information, and Terminal Device

A method for receiving downlink control information comprising:

• blindly detecting, by a machine type communication user equipment, control information scrambled by a random access radio network temporary identity in multiple enhanced physical downlink control channel resources of a narrowband downlink transmission channel resource, wherein the multiple enhanced physical downlink control channel resources and one physical downlink data channel resource constitute the narrowband downlink transmission channel resource, and wherein the multiple enhanced physical downlink control channel resources jointly control the one physical downlink data channel resource;
• and
• receiving, by the machine type communication user equipment, downlink control information in an enhanced physical downlink control channel resource where the blindly-detected control information is located.

A method for transmitting downlink control information comprising sending downlink control information scrambled by a system information radio network temporary identity or a paging radio network temporary identity to a machine type communication user equipment in multiple enhanced physical downlink control channel resources, wherein the multiple enhanced physical downlink control channel resources and one physical downlink data channel resource constitute a narrowband downlink transmission channel resource, and wherein the multiple enhanced physical downlink control channel resources jointly control the one physical downlink data channel resource.

A communication apparatus for configuring a narrowband downlink transmission channel resource, the apparatus comprising:

• a first configuring unit configured to separate one narrowband downlink transmission channel resource from a system downlink data channel resource, so that a machine type communication user equipment receives downlink control information or downlink data information using the narrowband downlink transmission channel resource;
• and
• a second configuring unit configured to divide the narrowband downlink transmission channel resource into one physical downlink data channel resource and multiple enhanced physical downlink control channel resources, wherein the multiple enhanced physical downlink control channel resources jointly control the one physical downlink data channel resource.

A terminal device comprising:

• a blind-detecting unit configured to blindly detect, by a machine type communication user equipment, control information scrambled by a random access radio network temporary identity in multiple enhanced physical downlink control channel resources of a narrowband downlink transmission channel resource, wherein the multiple enhanced physical downlink control channel resources and one physical downlink data channel resource constitute the narrowband downlink transmission channel resource, and wherein the multiple enhanced physical downlink control channel resources jointly control the one physical downlink data channel resource;
• and
• a receiving unit configured to receive, by the machine type communication user equipment, downlink control information in an enhanced physical downlink control channel resource where the blindly-detected control information is located.

An apparatus for transmitting downlink control information comprising a first sending unit configured to send downlink control information scrambled by a system information radio network temporary identity or a paging radio network temporary identity to a machine type communication user equipment in multiple enhanced physical downlink control channel resources, wherein the multiple enhanced physical downlink control channel resources and one physical downlink data channel resource constitute a narrowband downlink transmission channel resource, and wherein the multiple enhanced physical downlink control channel resources jointly control the one physical downlink data channel resource.
