Abstract: A method in a communication node for mapping symbols of an Enhanced Physical Downlink Control Channel EPDCCH message is provided. The EPDCCH comprises one or more aggregation levels. For each aggregation level an EPDCCH message is constituted by a set of Control Channel Elements eCCEs. Each eCCE is mapped to a set of multiple enhanced Resource Element Groups eREGs wherein each eREG is a group of Resource Elements REs in a Physical Resource Block PRB pair. The communication node maps the symbols of the EPDCCH message to the set of REs that constitutes the multiple eREGs that the set of eCCEs correspond to. The order in which the EPDCCH symbols are mapped to the set of REs is dependent on the aggregation level. Publ.

Abstract: 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.

Abstract: In one aspect the teachings herein provide a system and method for reusing the PUCCH format 3 to address the new HARQ ACK feedback cases encountered in Rel 11 where different UL/DL configurations are involved in the CA configuration of a UE such as Rel 11 interband TDD CA with different UL/DL configurations on different bands. The various embodiments illustrated by way of example in this disclosure enable reliable and efficient HARQ ACK feedback for Rel 11 TDD CA without a substantial increase in specification and implementation complexity.

Abstract: Some embodiments provide a method for transmitting a downlink control channel in at least one block of resources. The downlink control channel comprises a set of resource element groups. The method may be executed by a transmitting node e.g. an eNB. The transmitting node first determines whether to transmit the downlink control channel using localized or distributed transmission. Responsive to determining to use localized transmission the transmitting node performs the transmission such that all resource element groups in the set that are comprised in the same block of resources are mapped to the same antenna port and the antenna port depends on which subset of resource element groups in the block of resources are used for the downlink control channel.

Abstract: A new uplink control channel capability is introduced to enable a mobile terminal to simultaneously report multiple packet receipt status bits and channel condition bits. In an example embodiment implemented in a mobile terminal the mobile terminal (first determines (1310) that channel state information and hybrid ARQ ACK/NACK bits corresponding to a plurality of downlink subframes or a plurality of downlink carriers or both are scheduled for transmission in an uplink subframe. The mobile terminal then determines (1320) whether the number of the hybrid ARQ ACK/NACK bits is less than or equal to a threshold number. If so the mobile terminal transmits (1330) both the channel state information and the hybrid ARQ ACK/NACK bits in physical control channel resources of the first uplink subframe on a single carrier. In some embodiments the number of the hybrid ARQ ACK/NACK bits considered in the previously summarized technique represents a number of ACK/NACK bits after ACK/NACK bundling.
