    Abstract: A signal having a frame structure is transmitted and received in a cell by a first base station, the structure of the frame having a downlink frame part and an uplink frame part. Each frame part has the ability of carrying at least one data region allocated to at least one user or broadcasted for the traffic flow between the telecommunication network and the user terminal via the first base station. The downlink frame part has an overhead part with at least synchronization or system information. The frame structured signal is transmitted periodically Frame N, Frame N+1, Frame N+2, Frame N+3 with a normal interval defined by the system. The system during, a power saving mode, increases the interval between at least a first and the next following second frame structured signal to a power saving interval.

    Abstract: Method of communicating frames of digital data by OFDM modulated signals comprising a first plurality of payload carrying sub-channels and a second plurality of pilot carrying sub-channels, whereby consecutive frames of payload data is are associated with a given pilot configuration and transmitted. Prior to the transmission of a frame of payload data, each of the plurality of pilot configurations are evaluated with regard to PAPR, whereby the pilot configuration being associated with the lowest PAPR value is beingchosen for transmission.

    Abstract translation: 通过OFDM调制信号来传送数字数据帧的方法，该OFDM调制信号包括承载子信道的第一多个有效负载和第二多个导频携带子信道，由此连续的有效载荷数据帧与给定的导频配置相关联并发送。 在传输有效载荷数据帧之前，针对PAPR评估多个导频配置中的每一个，由此与最低PAPR值相关联的导频配置被选择用于传输。

    Abstract: La presente invención se refiere a un método para ahorrar energía en un sistema de telecomunicación con por lo menos una primera estación de base para permitir comunicación dentro de una célula. Una señal 23 que tiene una estructura de marco es transmitida y recibida en la célula por la primera estación de base, la estructura del marco comprende una parte de marco de enlace descendente 15 y una parte de marco de enlace ascendente 16. Cada parte de marco 15, 16 tiene la capacidad de llevar por lo menos una región de datos 19, 21 asignada a por lo menos un usuario o difundida para el flujo de tráfico entre la red de telecomunicación y la terminal de usuario a través de la primera estación de base. La parte de marco de enlace descendente 15 comprende una parte de carga de protocolo con por lo menos una información de sincronización 17 o una información de sistema 18. La señal con estructura de marco 23 es transmitida periódicamente Marco N, Marco N+1, Marco N+2, Marco N+3 con un intervalo normal definido por el sistema. El método se caracteriza particularmente porque durante un modo de ahorro de energía el sistema incrementa el intervalo entre por lo menos una primera señal con estructura de marco 23 y la segunda señal siguiente con estructura de marco 23 a un intervalo de ahorro de energía.
