Abstract: In a first subframe, data is sent by a network node in a DL shared channel and a timing indicator is sent in a PDCCH to UE, the timing indicator indicating an offset relative to the first subframe the UE should use in order to determine a second subframe to use to send, in a PUCCH, acknowledgement information for the data received in the DL shared channel of the first subframe. The acknowledgement information is received by the network node from the UE in the PUCCH of the second subframe. The UE receives the data and timing indicator and determines the second subframe using at least the timing indicator. The UE transmits the acknowledgement information in the PUCCH of the second subframe. Apparatus, computer programs and products, and methods are disclosed.

Abstract: Systems, methods, apparatuses, and computer program products for the transmission of uplink (UL) control information via unlicensed spectrum are provided. One method includes dynamically allocating, by a network node, control channel resources for transmitting of uplink control information (UCI). The method may also include scheduling a user equipment with multiple transmission opportunities for each hybrid automatic repeat request (HARQ) acknowledgement/non-acknowledgement (A/N) on the control channel in multiple uplink subframes.

Abstract: Systems, methods, apparatuses, and computer program products for aperiodic channel state information (CSI) reporting for enhanced carrier aggregation are provided. One method includes transmitting, by a network node, a configuration of at least two aperiodic channel state information (A-CSI) reporting modes per one or more configured downlink (DL) component carriers (CC) to at least one user equipment. The method may also include transmitting an aperiodic channel state information (A-CSI) trigger to the at least one user equipment. The transmitting of the A-CSI trigger may cause the at least one user equipment to dynamically switch between the two configured aperiodic channel state information (A-CSI) reporting modes.
