摘要： The invention relates to a method in a radio base station for scheduling data transmissions to a user equipment in a first cell. The radio base station is comprised in a telecommunications network comprising at least the first cell and a second cell wherein the radio base station serves at least the first cell. A transmission time of the first cell is divided into a first radio frame comprising a first number of subframes synchronised to a clock. A transmission time of the second cell is divided into a second radio frame comprising an equal number of subframes of equal time length as the first radio frame. The second radio frame is being synchronised to the same clock as the first radio frame. The radio base station receives a first data transmission to be transmitted the user equipment in the first cell, schedules the first data transmission to a minimum of subframes of a first radio frame of the first cell, and transmits the first radio frame offset in time in relation to a second radio frame of the second cell for minimizing simultaneously data transmissions within the cells.

摘要： A data communication scheduling system (300) of a radio base station (100) serving multiple cells (10-30) comprises multiple radio equipment, REs, (101-103) and antenna interfaces (115, 125, 135) connectable to antennas (110, 120, 130). In order to reduce the power consumption, only a subset of the RE (101) is active, while the other REs (102, 103) are turned off. A transmitter controller (155) is arranged for controlling the active RE (101) to be shared among multiple cells (10-30) during a radio frame (40) so that each cell (10-30) is guaranteed at least one sub frame (50-58) for downlink transmission. A receiver antenna system multiplexer(140) selectively interconnects the active RE (101) with the antenna interfaces (115, 125, 135) according to the operation of a receiver controller (145). Consequently, the RE (101) becomes connected to different antenna interfaces (115, 125, 135) during different sub frames (50-58) to thereby allow each cell (10-30) at least one assigned uplink sub frame (53-55) in the radio frame (40) at a predefined sub frame distance after the at least one downlink sub frame (50-52) assigned to the same cell (10-30).

摘要： In cellular radio systems it is a problem to provide service to UE (user equipment) on the cell border. In systems that apply a frequency re-use of one, and OFDM access technology, the uplink direction need be improved. One embodiment of this application relates to a radio base station that is equipped with one or more FFT processor/s in addition to the FFT-processor that is adapted for being adjusted to the timed aligned arrival of signals from UE served by the radio base station. The additional FFT processor/s is adapted for being adjusted to the arrival of one or more signals from UE that are served by other radio base station/s. The radio base station is further adapted to send Fourier processed signal information relating to the UE of the other radio base station/s and thereby assist the other radio base station in signal reception. The application also relates to a method for assisting another radio base station in signal reception, and to a method for receiving assistance from another radio base station in signal reception.

摘要： In a radio communication network there are a number of radio base stations, at least one of which belongs to a first radio access network and manages at least one active cell serving user equipment. It is determined whether a passive other cell of a radio base station belonging to a second overlapping radio access network should be activated based on information representative of radio access preferences of the user equipment (S1). When it is determined that the passive other cell should be activated, the passive cell is requested to be activated by causing the corresponding radio base station belonging to the second overlapping radio access network to start transmission of cell-defining information (S2).

摘要： A radio communication network (1) comprises at least a radio base station (10) serving an active cell (15) and a radio base station (20, 30, 40) having a passive cell (25, 35, 45) and does not transmit any cell-defining information for the passive cell (25, 35, 45). User equipment (100) receives random access enabling information applicable to the passive cell (25, 35, 45) from the radio base station (10) serving the active cell (15). The user equipment (100) uses this information for compiling and transmitting a random access to the radio base station (20, 30, 40) of the passive cell (25, 35, 45). Upon reception of the random access, the radio base station (20, 30, 40) activates its passive cell (25, 35, 45) and starts transmission of cell-defining information for the now activated cell (25, 35, 45) to assist user equipment (10) in finding the cell (25, 35, 45) for radio communication service.

摘要： A method of amplifying signals for transmission includes generating a signal in each of a plurality of subsystems. The subsystems each implement one of a plurality of radio access networks such that at least two different radio access networks are implemented. The method further includes amplifying signals generated by the subsystems with a power amplifier capable of amplifying input signals to a maximum power. The method also includes generating in each subsystem a power demand indicative of a power requested by that subsystem. Additionally, the method includes assigning a portion of the maximum power to each subsystem based upon the demands.

摘要： Buffer circuitry receives data to be processed by electronic circuitry using a first clock signal associated with a first clock domain. The buffered data is output using a second clock signal associated with a second clock domain. The buffering of the data is associated with a buffering delay. Counting circuitry receives at a start count input a write timing signal associated with the first clock domain and with writing data to the buffer circuitry. The counting circuitry receives at a stop count input a read timing signal associated with the second clock domain and with reading data from the buffer circuitry. A count value accumulated between receiving the write timing signal and the read timing signal corresponds to the buffering delay. Control circuitry performs a control operation based on the count value.

摘要： A method for combining signals being conveyed across a digital interface is disclosed. In one embodiment, a subharmonic of a frequency is superimposed on asynchronous data. The subharmonic can be used to carry a frequency reference across the digital interface. In another embodiment, a time stamp algorithm is used to carry a time reference from a master circuit to a slave circuit across a digital interface. The transmission delay between the master circuit and slave circuit is measured. The master circuit transmits time correction messages to the slave circuit, based on the time the correction message is transmitted plus the transmission delay. In another embodiment, a reset signal is carried across a digital interface by discontinuing the transfer of a frequency reference for a predetermined time. A lowpass filter can be used at the receiving side of the interface to recognize the absence of the frequency reference and initiate a reset procedure at that side.
