    摘要： A repeater device (R) for use in a radio communication system comprises a detector (44), arranged for detecting any existence of radio signaling to and/or from a user terminal being situated in a vicinity of the repeater device (R). The repeater device (R) further comprises an amplifier arrangement (46), arranged for amplifying uplink and/or downlink traffic and means (48) for activating the amplifier arrangement. The means (48) for activating the amplifier arrangement is arranged for activating the amplifier arrangement (46) as a response to an existence of the radio signaling. A method for controlling operation of a repeater in radio communication system comprises detecting, in the repeater, of radio signaling to and/or from a user terminal being situated in a vicinity of the repeater. Amplification in the repeater is activated as a response to an existence of the radio signaling and uplink and/or downlink traffic is amplified.

    摘要： A method performed by a master node, for handling Bluetooth connections to slave devices is provided. The master node allocates to a first group, a first set of channels, and to a second group a second set of channels. The first set of channels relates to a first part of a frequency band supported by the master node, and the second set of channels relates to a second part of the frequency band that is different from the first part of the frequency band. The master node assigns to the first group, a first connection between the master node and a first slave device, to use channels comprised in the first set of channels. The master node then attenuates for the connection in the first group, signals relating to any other group being allocated a set of channels, including the second group.

    摘要： A transmitting node and a method therein for controlling a transmission rank in a wireless communications system. The wireless communications system comprises the transmitting node and a receiving node. The transmitting node is configured to transmit on multiple antennas according to the transmission rank. The transmitting node allocates one or more first transmission resources between the transmitting node and the receiving node to operate according to a first transmission rank, and one or more second transmission resources between the transmitting node and the receiving node to operate according to a second transmission rank. When a performance of the second transmission rank outperforms a performance of the first transmission rank, the transmitting node configures at least one of the one or more first transmission resources to operate according to the second transmission rank.

    摘要： The present invention increases the interference diversity in systems with the frame structure described above by using frequency hopping sequences that are selected considering characteristics of the channel relating to how the channel varies. According to a first embodiment, the channel characteristics relate to channel coherence time and according to a second embodiment, the channel characteristics relate to channel coherence bandwidth. For channels with long coherence times, the transmission hops back and forth several times during a TTI on the different available frequencies. For channels with wide coherence bandwidths, hopping may be performed between the frequency used by the reference signals and its neighbor frequencies. For channels with both long coherence times and wide coherence bandwidths, a combination may be used.
