摘要： A method in a user equipment for estimating a channel upon receiving an enhanced control channel, eCCH, from a network node in a telecommunications system. The eCCH is distributed over multiple resource block pairs, wherein each of the multiple resource block pairs comprises a number of resources. Each resource is associated with a respective antenna port. The user equipment identifies an antenna port being associated with more than one resource. The more than one resource is present in different resource block pairs of the multiple resource block pairs over which the eCCH is distributed. The identifying is based on how the eCCH is mapped to the multiple resource block pairs. Also, the user equipment estimates the downlink channel for the eCCH based on the identified antenna port in the more than one resource in the multiple resource block pairs. A user equipment, a method in network node and a network node are also provided.

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.

摘要： 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.

摘要： Devices and methods for transmitting information in resource blocks between a base station and one or more communication devices are disclosed. In each resource block (RB) used for a data or control channel transmission, a plurality of non-over!apping regions of resource elements (REs) are defined. Each region is associated with one or multiple unique reference symbols (RSs), and may be further associated with one or more antenna ports. When user equipment (UE) demodulates the information it receives in a particuiar region of an RB, it uses the RS and/or antenna port associated with that region. The RS and/or antenna port information may be used, for example, to estimate a channel of the communication network or to demodulate and decode the data contained within the associated regions.

摘要： 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.
