摘要： A method and base station for forming an OFDM signal from a baseband signal includes a partitioning unit configured to partition a block of baseband signal samples into sub-blocks. A sub-carrier mapper maps the sub-blocks onto adjacent sub-carrier blocks of an OFDM multi-carrier to form corresponding unprefixed OFDM symbols. A cyclic prefix adder adds a cyclic prefix to each mapped sub-block to form prefixed OFDM symbols. Phase compensations force the unprefixed OFDM symbol part of all subsequently up-converted prefixed OFDM symbols to start at the same phase. Up-converters up-convert the phase compensated prefixed OFDM symbols to respective radio frequency bands having center frequencies and bandwidths that preserve the OFDM multi-carrier structure. A combiner combines the up-converted phase compensated prefixed OFDM symbols into an OFDM signal.

摘要： The present invention relates to radio base stations including a standardized interface CPRI between a Radio Equipment (RE) and a Radio Equipment Controller (REC). The present invention also relates to a method. The problem addressed is how to convey calibration information from the RE to the REC, when the capacity is occupied by radio IQ samples. The solution is to suppress the IQ samples to get capacity for the calibration information. Various embodiments of the invention focus on reducing the negative impact the suppression of IQ data may have on detecting the signals received.

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.
