    • 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.
    • 一种用于向电信系统中的用户设备发送增强型控制信道eCCH的网络节点中的方法。 eCCH包括至少一个控制信道元素CCE中的用户设备的控制信息。 至少一个CCE映射到包括在至少一个增强的资源元素组中的多个资源元素。 所述至少一个增强型资源元素组包括在时频正交频分复用OFDM,网格中的至少一个资源块中。 网络节点决定使用小于第一eCCH的物理下行链路控制信道PDCCH的最小CCE聚合级别的CCE聚合级别。 然后,当较小的CCE聚合级别用于第一eCCH时,网络节点通过使用比正交相移键控QPSK调制更高阶调制来调制第一eCCH。 然后,网络节点将调制的第一eCCH映射到至少一个资源块中的资源元素的至少一个增强资源元素组,并将映射的第一eCCH发送给用户设备。 还提供了网络节点,用户设备中的方法和用户设备。

    • A method in a network node for transmitting control information to a user equipment in a telecommunications system is provided. The control information is scheduled in time intervals of a downlink shared data channel, wherein the control information is allocated resource elements in resource blocks of a time-frequency Orthogonal Frequency Division Multiplexing, OFDM, grid in the time intervals in which the control information is scheduled. The network node determines for a time interval, a set of user equipments for which control information is scheduled in the time interval. Also, it selects for a user equipment comprised in the determined set of user equipments, at least one group of user equipments amongst one or more groups of user equipments to which the user equipment is assigned. It also prepares a group signal corresponding to the selected one group of user equipments by allocating resource elements in the resource blocks of the time interval to the group signal. Furthermore, the network node transmits the prepared group signal in the allocated resource element in the time interval to the user equipment such that the user equipment is enabled to determine whether the control information that is allocated resource elements in the time interval is intended for the user equipment or not. A network node, a method in user equipment and a user equipment are also provided.

    • A transmitting node uses different reference signal sequences for different types of enhanced control channels. An example method begins with generating (1410) a first reference signal sequence, from a first initialization value, and generating (1420) a second reference signal sequence, from a second initialization value. These reference signal sequences are associated with two corresponding enhanced control transmissions. A first enhanced control channel and reference symbols taken from the first reference signal sequence are transmitted (1430), using first time-frequency resources and a first set of transmission points or a first set of antenna ports or both, and a second enhanced control channel and reference symbols taken from the second reference signal sequence are also transmitted (1440), using a differing second set of transmission points and/or a differing second set of antenna ports and/or a differing second set of time-frequency resources, in the same subframe or group of subframes.
