Abstract: A method comprises transmitting from a user device information on first and second hybrid automatic request acknowledgement bits and a scheduling request in a same transmission time interval. The information on said first and second hybrid automatic request acknowledgement bits and said scheduling request are transmitted via first and second physical resource blocks using one or more resources of a set of resources. At least one of the resources of the set of resources differs from the one or more resources of the set of resources used to transmit information on the first and second hybrid automatic request acknowledgement bits when there is no scheduling request.

The network node (e NB) defines (401) a downlink assignment index of the scheduled carrier having at least the lowest carrier index from the list of configured carriers, based on a total number of scheduled carriers.

The network node (e NB) receives (405) from the terminal device (UE), uplink control signalling indicating HARQ-ACKs related to physical downlink shared channels corresponding to the scheduled carriers.

Abstract: A radio network sends to a user equipment (UE) an indication that reduced processing time associated with a reduced search space is operational for the UE. The reduced search space is a sub-set of a larger search space associated with a non-reduced processing time. The network sends to the UE within the reduced search space downlink control information (DCI) in subframe N that allocates to the UE a radio resource. If the allocated radio resource is uplink, the network receives uplink data from the UE on the allocated radio resource in a subframe spaced from the subframe N an amount of the reduced processing time (N+reduced processing time); and/or if the allocated radio resource is downlink the network sends downlink data to the UE on the allocated radio resource in subframe N and receives from the UE in reply feedback (ACK/NACK) signaling in a subframe N+reduced processing time.

Abstract: Apparatuses and methods for transmission power control are disclosed. A given transmission resource and a first transmission power are determined (202, 204) for transmission. Prior to transmitting on the given transmission resource it is determined (206) whether the resource is occupied or unoccupied. Upon detecting that the resource is occupied, a second, reduced transmission power is determined (210) such that a transmission using the second, reduced transmission power would not render the resource as occupied. The determination of the second transmission power is based at least partially on a predetermined maximum transmission power reduction value. Transmission (212) is done utilizing the given transmission resource using the second transmission power according to the determination.
