Abstract: Resources for reference signalling on at least one component carrier of a plurality of aggregated component carriers can be determined by a station. Information indicative the at least one component carrier and the associated resources is then communicated to another station for configuration of the other station. A trigger is then sent for reference signalling, and in response to the trigger, at least one reference signal is sent from the other station using the indicated at least one component carrier and resources.

Abstract: Various communication systems may benefit from appropriate handling of uplink communications. For example, certain wireless communication systems may benefit from an uplink coverage extension for unlicensed band operation. A method can include configuring a first interlace having a first starting physical resource block. The method can also include configuring a second interlace having a second starting physical resource block offset from the first physical resource block. The method can further include transmitting or receiving a signal based on a combination of the first interlace and the second interlace. The combination can include at least one cluster but less than two clusters in each measurement interval.

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.

Abstract: A method for network synchronization of a first network element is provided, comprising: receiving, from each of at least two synchronization candidate network elements, a first synchronization accuracy value; determining, for each of the at least two synchronization candidate network elements, a signal quality indicator; determining for each synchronization candidate network element a second synchronization accuracy value based on the signal quality indicator and the first synchronization accuracy value related to the synchronization candidate network element, and selecting a synchronizing network element, for synchronizing the first network element to, from the at least two synchronization candidate network elements, based on the determined second synchronization accuracy values. The present disclosure enhances the performance of RIB network synchronization by indicating an estimate of an accumulated synchronization error magnitude. The indication is beneficial for RIB source network element or source cell selection and it could help to make the topology of synchronized network elements/cells more reasonable.

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 an 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.
