Abstract: The invention relates to a method in a first communication device of receiving control information over a radio channel from a second communication device. The first communication device receives a subframe over the radio channel, and determines whether the subframe is a downlink subframe with downlink assignment intended for the first communication device by reading data in the subframe. That being the case, the first communication device decodes data within the subframe, and determines whether any data packet being sent from the second communication device before the subframe has been missed by analyzing an indicator associated to the subframe in the data. The indicator provides knowledge about previous downlink subframes with downlink assignment intended for the first communication device.

Abstract: A technique for operating a network node in a heterogeneously deployed network comprising network nodes of different nominal transmit powers and at least partially overlapping coverage areas is described. A method implementation of this technique comprises a step of operating the network node in a base mode in which the network node is configured to transmit terminal-specific demodulation reference signals for a first set of terminal devices. The method comprises the further step of selectively activating or deactivating operation of the network node in a Single Frequency Network (SFN) mode in which the network node is configured to transmit, for a second set of terminal devices, the same cell-specific reference nodes as a another network node of the heterogeneously deployed network that has a larger nominal transmit power.

Abstract: Some embodiments herein relate to method in a user equipment (10) for determining a transmit power to be used by the user equipment when transmitting in a radio communications network, which user equipment (10) is served by a radio network node (12,12') in the radio communications network. The user equipment (10) receives, from the radio network node (12,12'), an indication indicating a set of power control parameters out of multiple sets of power control parameters, which multiple sets of power control parameters are stored at the user equipment (10). The user equipment (10) determines a transmit power based on the indicated set of power control parameters.

Abstract: A first communication device (10) and a method in a first communication device for receiving control information and data over a radio channel from a second communication device are disclosed. The first communication device comprises a receiving arrangement (103) adapted to receive a subframe of a radio frame, and a control unit (101) arranged to determine whether the subframe is a subframe with downlink resource assignment intended for the first communication device. When that being the case, the control unit is further arranged to determine whether any downlink assignement for data, that has been scheduled in and sent from the second communication device previous the subframe, has been missed by analysing an indicator associated to the subframe. The indicator is arranged to provide information of previous subframe with downlink resource assignments intended for the first communication device. A second communication device (20) and a method in a second communication device for transmitting control information and data over a radio channel to a first communication device in a subframe with a downlink resource assignment intended for the first communication device are disclosed. The second communication device comprises a control unit (201) arranged to add an indicator to the subframe arranged to provide information of previous subframes with a downlink resource assignment intended for the first communication device in the control information to the first communication device, and a transmitting arrangement (205) arranged to transmit the control information and data with the subframe to the first communication device.

Abstract: La présente invention utilise des ressources spécifiques à un utilisateur, telles qu'allouées sur la liaison montante, pour transporter un ou plusieurs signaux de référence de sondage (srs) spécifiques à une antenne. Cette technique permet par exemple à un équipement d'utilisateur (ue) configuré pour un fonctionnement de liaison montante en mode entrée multiple/sortie multiple (mimo) d'envoyer de façon avantageuse des srs spécifiques à une antenne dans le cadre des ressources accordées allouées à l'ue via un ou plusieurs octrois de liaison montante programmés. Ainsi, à l'intérieur des ressources accordées allouées par un octroi de liaison montante donné, un ue utilise au moins une partie de ces ressources pour envoyer des srs spécifiques à une antenne plutôt que pour envoyer des données de liaison montante (trafic utilisateur). La présente invention comprend donc, dans un ou plusieurs modes de réalisation, un procédé, au niveau de l'ue, de transmission de srs spécifiques à une antenne pour deux antennes d'émission de liaison montante ou plus. Le procédé comprend la transmission d'un signal de référence de sondage spécifique à une antenne pour au moins une des antennes d'émission de liaison montante à l'intérieur d'une ressource accordée allouée à l'équipement d'utilisateur pour une transmission de données de liaison montante programmée.
