Abstract
A method for transmission of control data to a user equipment in a mobile telecommunication system, wherein the method comprises sending control data to the user equipment in a data transmission, and performing, by the user equipment, a blind decoding of transmission elements within the data transmission in order to detect the control data in a data region in the data transmission.
Claims14
A method for transmission of control data to a user equipment in a mobile telecommunication system, wherein the method comprises:
- sending control data to the user equipment in a data transmission, wherein the data transmission has a first control data region and a second control data region, wherein the first control data region and the second control data region are located in a data region of the data transmission and the data transmission is free of a control region in the data transmission preceding the data region, wherein the first control data region comprises common control data for different user equipments, and wherein the second control data region comprises user-equipment-specific control data for said user equipment;
- performing, by the user equipment, a blind decoding of transmission elements within the data transmission in order to detect the control data in the data region in the data transmission.
A user equipment for a mobile telecommunication system, wherein control data is to be transmitted to the user equipment in the mobile telecommunication system, wherein the user equipment comprises:
- a receiver adapted to receive control data in a data transmission, wherein the data transmission has a first control data region and a second control data region, wherein the first control data region and the second control data region are located in a data region of the data transmission and the data transmission is free of a control region in the data transmission preceding the data region, wherein the first control data region comprises common control data for different user equipments, and wherein the second control data region comprises user-equipment-specific control data for said user equipment;
- and
- a decoder for performing a blind decoding of transmission elements in the data region within the data transmission in order to detect the control data in the data transmission.
A control node for a mobile telecommunication system, wherein the control node comprises:
- a transmitter for sending control data to a user equipment in a data transmission, wherein the data transmission has a first control data region and a second control data region, wherein the first control data region and the second control data region are located in a data region of the data transmission and the data transmission is free of a control region in the data transmission preceding the data region, wherein the first control data region comprises common control data for different user equipments, and wherein the second control data region comprises user-equipment-specific control data for said user equipment;
- an encoder for encoding of transmission elements within the data transmission in order to enable the user equipment to detect the control data in the data region in the data transmission by a blind decoding of the transmission elements.
A mobile telecommunication system for transmission of control data, wherein the mobile telecommunication system comprises
- a user equipment, the user equipment comprising:
- a receiver adapted to receive control data in a data transmission, wherein the data transmission has a first control data region and a second control data region, wherein the first control data region and the second control data region are located in a data region of the data transmission and the data transmission is free of a control region in the data transmission preceding the data region, wherein the first control data region comprises common control data for different user equipments, and wherein the second control data region comprises user-equipment-specific control data for said user equipment;
- and
- a decoder for performing a blind decoding of transmission elements in the data region within the data transmission in order to detect the control data in the data transmission, and
- a control node, the control node comprising:
- a transmitter for sending control data to a user equipment in the data transmission;
- and
- an encoder for encoding of transmission elements within the data transmission in order to enable the user equipment to detect the control data in the data region in the data transmission by a blind decoding of the transmission elements,
- wherein the control data is to be transmitted from the control node to the user equipment.
