Abstract
The invention relates to a method, apparatus and system for configuring control channels in a mobile communication network and a mobile station. In order to suggest another improved scheme for configuring control channels, in particular control channels related to the transmission of user data the invention suggests aligning the size of the control channel information of different formats to an equal number of coded control channel information bits and/or modulation symbols for each control channel. The control channels may comprise scheduling related control information. According to another aspect of the invention, a more flexible solution is proposed that may allow for taking different geometries of mobile stations within a cell into account. Similar to the aspect above, the size of the control channel information is aligned by means of modulation and/or coding, however the control channel information is aligned to one out of a set of numbers of coded control channel information bits and/or modulation symbols for each control channel.

47. A method for transmitting control information of a plurality of control information formats on control channels in a mobile communication system, wherein each of the control channels is configured according to one of a plurality of control information formats differing in their number of bits, the method comprising:
-
coding the control information of the control channels to generate coded control information bits, modulating the coded control information bits of the control channels using a given modulation scheme to generate modulated control information, and transmitting the modulated control information of a respective control channels on physical resource elements, the coding step is generating for each control channel a number of coded control information bits that is an integer multiple of a smallest allowed number of coded control information bits for all control information formats. - View Dependent Claims (48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60)

61. A base station for transmitting control information of a plurality of control information formats on control channels in a mobile communication system, wherein each of the control channels is configured according to one of plural control information formats differing in their number of bits, wherein the base station comprises:
-
a coder that codes the control information of the control channels to thereby generate coded control information bits, a modulator that modulates the coded control information bits of the control channels using a given modulation scheme to generate modulated control information, and a transmitting entity that transmits for a respective control channel its modulated control information on physical resource elements, the coder is adapted to generate a number of coded control information bits that is an integer multiple of a smallest allowed number of coded information bits for all control information formats.

62. A mobile station for receiving control information of a plurality of control information formats on control channels in a mobile communication system, wherein each of the control channels is configured according to one of plural control information formats differing in their number of bits, wherein the mobile station comprises:
-
a receiver that receives a number of physical resource elements comprising modulated control information of at least one of the control channels, a demodulator that demodulates the modulated control information of the at least one control channel using a given modulation scheme to obtain coded control information bits of the control channels, and a decoder that decodes the coded control information bits of the at least one control channel, the demodulator is adapted to obtain a number of coded control information bits that is an integer multiple of a smallest allowed number of coded control information bits for all control information formats. - View Dependent Claims (63)
