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: 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.

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: 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: Disclosed is a method for use in a radio communications system including multiple radio base stations and multiple radio terminals. The method includes determining a first positioning reference signal for a first cell associated with a first radio base station that is based on a first identifier associated with the first cell and determining a second positioning reference signal for a second cell associated with a second radio base station that is based on a second identifier associated with the second cell. A radio terminal is capable of detecting the first and second positioning reference signals. Information is obtained in a positioning reference signal that the first and second base stations transmitted a same cell identifier and different positioning reference signals. Based on that obtained information, a collision is determined between the first and second cell identifiers. The collision is then resolved by associating a different, non-conflicting cell identifier to either of the first cell or the second cell.
