Abstract: A radio network device is operative to transmit uplink data on a physical uplink shared channel aggregating two or more contiguous slots. The device is further operative to transmit, in addition to the uplink data, Uplink Control Information (UCI) in at least one of the aggregated slots. The UCI may comprise a HARQ ACK/NACK. The UCI is configured in response to Downlink Control Information (DCI) received from a serving network node. The DCI also includes a UL scheduling grant for the physical uplink channel.

The subcarriers may be non-contiguous. In slot aggregation, the UCI subcarriers may frequency hop from slot to slot. The UCI may be encoded differently in different slots, to facilitate early decoding by a receiver (which may, for example immediately prepare a re-transmission in the case of a NACK).

Abstract: A system and method to instruct a user equipment (UE) how Uplink Control Information (UCI) on a Physical Uplink Shared Channel (PUSCH) should be transmitted with carrier aggregation. A semi-static signaling of a UCI mapping bit (via a Radio Resource Control (RRC) parameter) is used by a base station such as an eNodeB to require the UE to transmit UCI using one of two pre-determined UCI transmission modes. The bit can be decided by the base station, considering, for example, the available bandwidth or quality of different Uplink Component Carriers (UL CCs) associated with the UE. This network-based solution allows the network to either configure a general rule of UCI transmission by the UE or to enforce the UCI transmission on the Uplink Primary cell (UL Pcell). Because of the rules governing abstracts, this abstract should not be used to construe the claims.
