  • Publication number: 20170288822
    Abstract: A method performed by a network node for managing transmission of Cell Reference Symbols, CRS, wherein the network node 110 operates one or more cells and the network node 110is configured to transmit the CRS in a first bandwidthmode. When the network node 110 has identified a cell 130 which is not actively serving any UEs 120, also referred to as an empty cell, the network node 110 applies(302) a reduced CRS bandwidth mode in the first cell 130 in relation to the first bandwidthmode. By applying (302) a reduced CRS bandwidth mode in the empty cell 130, the overall interference of the CRS from the empty cell 130 is reduced, thereby enhancing the performance in cells actively serving UEs 120.

  • Patent number: 8797957
    Abstract: A terminal (e.g., mobile communication device, UE) and a method are described herein for allocating a soft buffer after interacting with a network node (e.g., base station, eNB). In addition, a network node (e.g., base station, eNB) and a method are described herein that facilitates robust operations during a reconfiguration period while a terminal allocates a soft buffer located therein.

  • Patent number: 8412117
    Abstract: A filter arrangement (EFM) comprises a first terminal (T1) arranged for handling duplex radio antenna feeder signals for at least two transceiver modules (10, 20), a second terminal (T2) arranged for handling at least duplex signals for a first transceiver module (10), a third terminal (T3) arranged for outputting a first multi carrier power amplifier system input signal, said input signal representing a transmit signal from said first transceiver module (10), a fourth terminal (T4) arranged for receiving a multi carrier power amplifier system output signal, said output signal comprising an amplified representation of the transmit signals from said at least two transceiver modules, and wherein said first and said second terminal (T1, T2) are connected via first single filter means (RX), said second and said third terminal (T2, T3) are connected via second single filter means (TX1), said fourth and said first terminal (T4, T1) are connected via third single filter means (TX2).

  • Publication number: 20110143766
    Abstract: In a wireless communication system, a base station adaptively schedule CQI reports form mobile stations. By adaptively prioritizing the CQI report from the mobile station against the uplink traffic and control data, the CQI reporting rate avoids unnecessary overhead in the uplink while maintaining good performance. The CQI reports are requested in response to a calculated weighting factor which is based on channel coherence time that can be estimated by the base station. The adaptivity in the CQI reporting allows achieving an optimal tradeoff between uplink traffic data and downlink control feedback signaling.
