    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 utilising the given transmission resource using the second transmission power according to the determination.

    Abstract: Systems and techniques for joint transmission cooperative multi-point. A set of n CSI reference signal resources are to be measured by a user device. The n CSI reference signal resources include at least one CSI reference signal resource spanning over at least two transmission points. Channel state information feedback corresponding to each CSI reference signal resource is configured. Upon receiving CSI from the user device, at least one precoder is selected for coherent joint cooperative multipoint transmission based on inter-transmission point phase relationship information. A co-phasing factor is derived from transmitted precoders over a cross-cell CSI reference signal resource, the derivation including transmission of reference signals using first and second precoding vectors on two ports, computation of a third vector using feedback based on the precoded reference signals, and computation of the co-phasing factor based on the first, second, and third vectors.

    Abstract: A method comprises defining (401), in a network node (e NB), scheduled downlink carriers from a list of configured downlink carriers. 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) defines (401) the downlink assignment index for each other scheduled carrier having a higher carrier index from the list of configured carriers. The network node (e NB) transmits (402) to a terminal device (UE) a control message corresponding to each scheduled carrier, the control message indicating a downlink assignment scheduling a physical downlink shared channel, and comprising the defined downlink assignment index. 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: When triggering a user equipment (UE) to send a reference signal (SRS) the network configures the UE with multiple parameter sets, each having a timing indication. The UE's resource allocation grants multiple uplink (UL) subframes and identifies/selects one of those parameter sets. The timing indication of the selected set identifies one of the granted UL subframes, in one embodiment by counting only among the allocated/granted shortened UL subframes. This triggers the UE to send SRS in that identified shortened UL subframe. In one embodiment if no UL subframes in the grant are shortened this triggers the UE to send SRS in a subframe previous to all the allocated/granted multiple UL subframes. The same mechanism can be used to trigger feedback reports such as aperiodic channel state information or block ACK/NACK reports, where the different UL signaling being triggered is requested in the network's resource allocation to the UE.
