摘要： Embodiments herein relate to a method for controlling transmit power of a mobile terminal. The method is performed by a mobile terminal in a dual connectivity mode wherein the mobile terminal is configured to support two or more contemporaneous links, including a first link and a second link, with two or more wireless network access points. The mobile terminal independently calculates a respective unscaled uplink transmission power level for each link, based on a corresponding link-specific value. The mobile terminal calculates a respective scaling factor for each link based on a total-power constraint and on one or more of the following: uplink resource allocation to each link, such that the scaling factor for the first link allocated more resources than the second link is larger than the scaling factor for the second link, link quality for each link, such that the scaling factor for the first link having a better link quality than the second link is larger than the scaling factor for the second link, uplink buffer state for each link, such that the scaling factor for the first link having more uplink data to be sent than the second link is larger than the scaling factor for the second link, and priority for each link, such that the scaling factor for the first link having a higher priority than the second link is larger than the scaling factor for the second link. The mobile terminal further applies the respective scaling factor to each respective unscaled uplink transmission power level, to obtain corresponding scaled power levels. The mobile terminal furthermore transmits over the two or more contemporaneous links at the respective scaled power levels.

摘要： A radio node (705, 711) is configured to transmit, within a guard band of a first radio access technology (RAT), a radio signal (709) according to a second RAT. The radio node (705, 711) determines, based on a channel bandwidth (731) of the first RAT, one or more transmit parameters for transmission of the radio signal (709) according to the second RAT within the guard band of the first RAT, for transmission of the radio signal (709) to comply with emission limits for the first RAT. The one or more transmit parameters include a frequency position of the radio signal (709) within the guard band for the first RAT. The radio node (705, 711) also configures the radio node (705, 711) with the one or more transmit parameters for transmitting the radio signal (709) according to the second RAT within the guard band of the first RAT.

Related UEs, methods of operating a UE, and network nodes are also disclosed.

摘要： Techniques are provided to ensure that a terminal device is able to perform measurements efficiently when an on/off scheme is used by network nodes, particularly in a heterogeneous network environment. An example method, implemented in a network node, comprises obtaining a discovery signal window pattern, the discovery signal window pattern defining one or more discovery signal windows during which each of a plurality of cells is to transmit a corresponding discovery signal, and sending an indication of the discovery signal window pattern to a terminal device.

摘要： A base station in a communications network broadcasts a cell-specific instruction to a plurality of mobile terminals in a cell served by the base station. The cell-specific instruction indicates that an uplink symbol has been semi-statically configured for aperiodic sounding reference signal (SRS) transmission over multiple subsequent subframes. The base station dynamically determines that a first mobile terminal of the plurality of mobile terminals is to use the uplink symbol for SRS transmission in a given one of the multiple subsequent subframes. In response, the base station signals a first terminal-specific instruction to the first mobile terminal. The first terminal-specific instruction is distinct from the cell-specific instruction and indicates that the first mobile terminal is to use the uplink symbol for SRS transmission in the given subframe.
