    Abstract: Methods and devices are provided whereby scrambling codes can be set in an improved way. In accordance with one embodiment a method is provided in a User Equipment for generating a second scrambling code or a second scrambling code group. The UE is configured for multi carrier operation receiving downlink transmission from a Universal Mobile Telecommunications System Terrestrial Radio Access Network on a set of at least two downlink carriers including an anchor carrier and at least a first secondary carrier. The method comprises determining a first scrambling code or a first scrambling code group associated with a first cell on the anchor carrier; and deriving a second scrambling code or a second scrambling code group associated with a second cell on said first secondary carrier using a predefined rule defining the relation between the second scrambling code or second scrambling code group and the first scrambling code or scrambling code group. Hereby interference suppression / cancellation processing is enabled in a receiver of a UE on secondary cells in multi-carrier scenarios that do not transmit the SCH, while minimizing the need for overhead in terms of signaling of the scrambling codes for neighbouring cells in a UTRAN system. Methods and devices for E-UTRAN are also described.

    Abstract: A method of operating a network node arranged for cellular communication is disclosed. The network node is capable to operate according to a Radio Access Technology, RAT. The method comprises checking whether a channel in an unlicensed band is clear. If found that the channel is clear, the method proceeds with transmitting a reservation signal on the channel, transmitting data on the channel, and releasing the channel. The transmitting of the reservation signal further includes embedding information related to the transmitting entity and embedding information about scheduled recipient or recipients. The reservation signal may also include embedded information about a duration or end of the intended transmission. Methods for network nodes and communication devices, computer programs, network nodes and communication device are also disclosed.

    Abstract: Método ejecutado por un primer dispositivo de comunicaciones (101) que opera en una red de comunicaciones inalámbricas (100). El primer dispositivo de comunicaciones (101) determina (1101) uno o más parámetros para transmitir por un canal de control de enlace ascendente en una banda sin licencia a un segundo dispositivo de comunicaciones (102). El segundo dispositivo de comunicaciones (102) opera en la red de comunicaciones inalámbricas (100). El uno o más parámetros comprenden una indicación de una duración de un período de detección de canal. El primer dispositivo de comunicaciones (101) después transmite (1102) por el canal de control de enlace ascendente al segundo dispositivo de comunicaciones (102), aplicando el uno o más parámetros determinados. De acuerdo con un método ejecutado por el segundo dispositivo de comunicaciones (102) que opera en la red de comunicaciones inalámbricas (100), el segundo dispositivo de comunicaciones (102) determina (1301) uno o más parámetros. El segundo dispositivo de comunicaciones (102) después inicia la transmisión (1302) del uno o más parámetros determinados al primer dispositivo de comunicaciones (101).

    Abstract: Methods and devices are provided wherein a user equipment transmits using at least two uplink transmit antennas and receives a set of control signals in the downlink direction from a cellular network. The user equipment estimates a received signal quality for each control signal in said set of control signals and determines, based on said received signal quality, which control signals that have been reliably received. The user equipment derives one or more parameters related to the uplink transmit diversity operation using a subset of control signals from the set of control signals, said subset only including control signals determined as reliably received; and transmits in the uplink direction applying the derived one or more parameters to control the uplink transmit diversity operation. The accuracy of the transmit diversity parameter values derived/set by the UE can be improved. This will enhance the performance of the uplink transmit diversity and will also reduce interference to the neighbor cells.
