    摘要： According to some embodiments, a method in a wireless device comprises: receiving (1162) a control channel that includes control information that indicates a set of time and frequency resources allocated for the wireless device to receive a data transmission, wherein the set comprises (i) a first subset (14) of the indicated set of time and frequency resources allocated for the data transmission overlaps with time and frequency resources in one or more control regions (10a) and (ii) a second subset (12) of time and frequency resources from one or more control resource regions excluded for the data transmission; and receiving (1166) the data transmission in the first subset of time and frequency resources allocated for data transmission.

    摘要： A base station (300), a wireless device (302) and methods therein for supporting radio communication, wherein the base station (300) employs carrier aggregation with multiple carriers serving a primary cell, PCell, and at least one secondary cell, SCell. The base station (300) signals (3:3) an SCell status to the wireless device (302), the SCell status indicating whether the at least one SCell will be in active state where the base station (300) transmits downlink signals on a carrier serving the at least one SCell, or in inactive state where the base station (300) does not transmit downlink signals on the carrier serving the at least one SCell. Thereby, the wireless device (302) can adapt its behaviour depending on the signalled SCell status, e.g. by turning off its receiver and not perform any signal measurements when the SCell is in inactive state.

    摘要： Systems and methods relating to transmit power control are disclosed. In some embodiments, a method of operation of a radio access node for providing transmit power control commands to a wireless device for uplink (UL) transmission on a cell that operates in an unlicensed frequency spectrum is provided. The method comprises indicating, for the cell that operates in the unlicensed frequency spectrum, a dynamic Transmit Power Control (TPC) command using a downlink (DL) control channel which indicates a DL-UL allocation of upcoming subframes in the cell that operates in the unlicensed frequency spectrum. In some embodiments, the DL control channel is a common DL control channel. In some other embodiments, the DL channel is a common Physical Downlink Control Channel (PDCCH).
