摘要： The present invention relates to a method and a device for time synchronization of an RBS which has lost its GPS signal. The method in the time synchronization device comprises retrieving from the first radio base station a first timing advance value (710) used by the user equipment to adjust its transmission timing before the handover, and a measurement of a reception timing (720) of a random access preamble. The random access preamble is transmitted from the user equipment to the second radio base station during synchronization. The method also comprises retrieving (730) from the second radio base station a second timing advance value used by the user equipment to adjust its transmission timing after the handover, and determining (740) a time synchronization offset between the first and second radio base station based on the retrieved first timing advance value, the second timing advance value, and the measurement of the reception timing.

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 synchronized 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 synchronized 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 supporting radio base station (100) comprises an IQ sample provider (110) for extracting, in a selected subset of the available frequency band (A) and/or from a selected subset of the available antennas (B), so-called complementary IQ samples based on received radio signals including a radio signal originating from an uplink transmission of at least one UE served by a serving radio base station (200). The supporting radio base station (100) comprises an IQ sample transmitter (120) for transmitting the complementary IQ samples to the serving radio base station (200) to enable the serving radio base station to decode user data of the uplink transmission based on the complementary IQ samples together with own IQ samples provided by the serving radio base station (200). This will provide significant savings of bit rate for the exchange of IQ samples between the radio base stations.

摘要： The invention relates to an arrangement (130) in a radio base station (10) for handling data traffic within a cell of the radio base station (10), which radio base station (10) is comprised in a telecommunications network. The arrangement comprises a determining unit (131) arranged to determine a maximum power, which maximum power indicates available power to radio base station (10). In addition, the arrangement comprises a comparing unit (132) arranged to compare the maximum power to a threshold power value, and a handling unit (133) arranged to handle data traffic served by the radio base station (10) according to a shaper rule when the maximum power is below the first threshold power value. The shaper rule is defined to handle data traffic in such a way that an amount of data traffic transmitted over a time period is reduced consuming less power of the radio base station (10) than if the data traffic is handled according to a basic rule when the maximum power is above the threshold power value.
