Abstract: A base station determines a first set of PUCCH resources to use for a first set of UEs to send acknowledgment information to the base station for a first group of DL subframes. The first set of PUCCH resources starts at a first index. The base station determines a second set of PUCCH resources to use for a second set of UEs to send acknowledgment information to the base station for a second group of DL subframes. The second set of PUCCH resources starts at a second index. The UEs in the first set only use the first set of PUCCH resources. The UEs in the second set use the first and second sets of PUCCH resources. For an UL reception, acknowledgement information is received from the first UEs using the first set of PUCCH resources and from the second UEs using the first and second sets of PUCCH resources.

Abstract: The disclosure relates to methods and apparatuses for feedback messaging in a communication system. A station can include into a scheduling information entity an indication of aperiodic feedback messaging on a physical uplink control channel and dynamically send the scheduling information entity with the indication to a communication device configured for periodic feedback messaging to trigger aperiodic feedback messaging by the communication device on the physical uplink control channel. Upon receiving the scheduling information entity the device can determine that it includes the indication and in response to the determining send at least one aperiodic feedback message on the physical uplink control channel.

Abstract: The application relates to channel state feedback reporting in wireless communication networks and in particular to modifications of the procedure for reporting CSI as specified by section 7.2 of 3GPP TS 36.213 V10.3.0. and the corresponding RRC protocol as specified by 3GPP TS 36.331 V10.2.0. The current cycle for CSI measurement and reporting is such that the UE performs separate CSI measurements for each report. However, the coverage area of CSI measurement reporting is lower than other uplink reporting such as e.g. ACK/NACK on PUCCH which supports subframe repetition, leading to an imbalance. Therefore, it is rather clear that it is highly beneficial to support coverage extension for CSI reports. The issue then arises as to how to realize the CSI coverage enhancement on top of existing/evolving CSI reporting framework. The application proposes to realize said CSI coverage enhancement by reporting (450) the same CSI report multiple times from the UE (110) to an eNB (220).

Abstract: Disclosed are a method and a corresponding apparatus relating to wireless telecommunication systems and more particularly to efficient resource allocation schemes supporting transmission of multiple periodic channel state information (CSI) reports on the physical uplink control channel (PUCCH) during the same subframe while maintaining single carrier properties of the transmitted signal. The method includes determining that at least two reports to be transmitted on an uplink resource collide with respect to the uplink resource, applying at least one resource selection policy to the at least two reports and selecting a resource to be used for transmitting a plurality of the at least two reports.
