摘要:
A method in a network node for transmitting an enhanced Control CHannel, eCCH, to a user equipment in a telecommunications system. The eCCH comprises control information to the user equipment in at least one Control Channel Element, CCE. The at least one CCE maps to a number of resource elements comprised in at least one enhanced resource element group. The at least one enhanced resource element group is comprised in at least one resource block in a time-frequency Orthogonal Frequency Division Multiplexing, OFDM, grid. The network node decides to use a CCE aggregation level that is smaller than the smallest CCE aggregation level of a physical downlink control channel, PDCCH, for a first eCCH. The network node then modulates the first eCCH by using a higher order modulation than Quadrature Phase Shift Keying, QPSK, modulation, when the smaller CCE aggregation level is used for the first eCCH. Then, the network node maps the modulated first eCCH to the at least one enhanced resource element group of resource elements in the at least one resource block, and transmits the mapped first eCCH to the user equipment. A network node, a method in user equipment and a user equipment are also provided.
