A method in a network node for transmitting control information to a user equipment in a telecommunications system, which control information is scheduled in time intervals of a downlink shared data channel, wherein the control information is allocated resource elements of the downlink shared data channel in resource blocks of a time-frequency Orthogonal Frequency Division Multiplexing, OFDM, grid, the method comprising - determining (1005; 1101) for a time interval, T sub-frame, a set of user equipments for which control information is scheduled in the time interval, T sub-frame; - selecting (1005; 1102) for a user equipment comprised in the determined set of user equipments, at least one group of user equipments, PSIG, amongst one or more groups of user equipments, PSIGs, to which the user equipment is assigned; wherein when the user equipment is assigned to more than one PSIG said selecting further comprises: selecting the PSIG which comprises the highest number of user equipments for which control information are scheduled in the time interval, T sub-frame, or selecting the PSIG based on the transmission mode of the control information or on resource elements allocated to the control information; - preparing (1005; 1103) a group signal, PSICH, corresponding to the selected one group of user equipments, PSIG, by allocating resource elements of the downlink shared data channel in the resource blocks of the time interval, T sub-frame, to the group signal, PSICH; and - transmitting (1006; 1104) the prepared group signal, PSICH, in the allocated resource elements of the downlink shared data channel in the time interval, T sub-frame, to the user equipment wherein the group signal, PSICH, enables the user equipment to determine whether the control information that is allocated resource elements in the time interval, T sub-frame, is intended for the user equipment or not; and wherein a location of the allocated resource elements in the PSICH, and/or the selected PSIG, indicate a subset of blind decoding options for the control information to the user equipment. - determining (1005; 1101) for a time interval, T sub-frame, a set of user equipments for which control information is scheduled in the time interval, T sub-frame; - selecting (1005; 1102) for a user equipment comprised in the determined set of user equipments, at least one group of user equipments, PSIG, amongst one or more groups of user equipments, PSIGs, to which the user equipment is assigned; wherein when the user equipment is assigned to more than one PSIG said selecting further comprises: selecting the PSIG which comprises the highest number of user equipments for which control information are scheduled in the time interval, T sub-frame, or selecting the PSIG based on the transmission mode of the control information or on resource elements allocated to the control information; - preparing (1005; 1103) a group signal, PSICH, corresponding to the selected one group of user equipments, PSIG, by allocating resource elements of the downlink shared data channel in the resource blocks of the time interval, T sub-frame, to the group signal, PSICH; and - transmitting (1006; 1104) the prepared group signal, PSICH, in the allocated resource elements of the downlink shared data channel in the time interval, T sub-frame, to the user equipment wherein the group signal, PSICH, enables the user equipment to determine whether the control information that is allocated resource elements in the time interval, T sub-frame, is intended for the user equipment or not; and wherein a location of the allocated resource elements in the PSICH, and/or the selected PSIG, indicate a subset of blind decoding options for the control information to the user equipment.
